Institute
While the topic of artificial intelligence (AI) in multinational enterprises has been receiving attention for some time, small and medium enterprises (SMEs) have recently begun to recognize the potential of this new technology. However, the focus of previous research and AI applications has therefore mostly been on large enterprises. This poses a particular issue, as the vastly different starting conditions of various company sizes, such as data availability, play a central role in the context of AI. For this reason, our systematic literature review, based on the PRISMA protocol, consolidates the state of the art of AI with an explicit focus on SMEs and highlights the perceived challenges regarding implementation in this company size. This allowed us to identify various business activities that have been scarcely considered. Simultaneously, it led to the discovery of a total of 27 different challenges perceived by SMEs in the adoption of AI. This enables SMEs to apply the identified challenges to their own AI projects in advance, preventing the oversight of any potential obstacles or risks. The lack of knowledge, costs, and inadequate infrastructure are perceived as the most common barriers to implementation, addressing social, economic, and technological aspects in particular. This illustrates the need for a wide range of support for SMEs regarding an AI introduction, which covers various subject areas, like funding and advice, and differentiates between company sizes.
Purpose
This study operationalizes risks in stakeholder dialog (SD). It conceptualizes SD as co-produced organizational discourse and examines the capacities of organizers' and stakeholders' practices to create a shared understanding of an organization’s risks to their mutual benefit. The meetings and online forum of a German public service media (PSM) organization were used as a case study.
Design/methodology/approach
The authors applied corpus-driven linguistic discourse analysis (topic modeling) to analyze citizens' (n = 2,452) forum posts (n = 14,744). Conversation analysis was used to examine video-recorded online meetings.
Findings
Organizers suspended actors' reciprocity in meetings. In the forums, topics emerged autonomously. Citizens' articulation of their identities was more diverse than the categories the organizer provided, and organizers did not respond to the autonomous emergence of contextualizations of citizens' perceptions of PSM performance in relation to their identities. The results suggest that risks arise from interactionally achieved occasions that prevent reasoned agreement and from actors' practices, which constituted autonomous discursive formations of topics and identities in the forums.
Originality/value
This study disentangles actors' practices, mutuality orientation and risk enactment during SD. It advances the methodological knowledge of strategic communication research on SD, utilizing social constructivist research methods to examine the contingencies of organization-stakeholder interaction in SD.
While recent studies have demonstrated that events are fundamentally climate sensitive, this seems to not be fully considered in event research or corporate event practice. Thus, this study aims to identify the influencing factors that affect the acceptance of climate adaptation measures among decision-makers in the event industry. The analysis was divided into three main parts. First, the existing literature related to climate change in an events context was reviewed. Using 15 semi structured interviews, the findings from this review were then critically discussed with stakeholders in Germany involved in event planning. Finally, explicit climate adaptation measures were proposed and discussed. Based on all findings, there appears to be a low level of awareness of and interest in climate adaptation amongst German event industry players. There is an imminent need for further research on climate adaptation and for decision-makers to better prepare for climate change in order to counteract resulting negative impacts.

Das bedeutet die Baupläne und Zeichnungen werden frei zur Verfügung gestellt. Heimwerker und andere Interessierte sollen dadurch die Möglichkeit bekommen faserverstärkte Rohre eigenständig und günstig herzustellen. Die Entwicklung und Konstruktion der Wickelmaschine ist das Ergebnis einer Masterarbeit an der Hochschule Osnabrück.
Körperhaltung und Muskelspannung beeinflussen den Klang der Stimme. Aber gibt es auch einen Zusammenhang zwischen der motorischen Kontrolle der Nacken-, Gesichts- und Kieferregion und der Stimme? Die Pilotstudie mit 12 Sängerinnen ging dieser Frage nach und zeigt: Es ist sinnvoll, die motorische Kontrolle zu testen, wenn Patient*innen mit Stimmproblemen zur Physiotherapie kommen.
In modern times, closed-loop control systems (CLCSs) play a prominent role in a wide application range, from production machinery via automated vehicles to robots. CLCSs actively manipulate the actual values of a process to match predetermined setpoints, typically in real time and with remarkable precision. However, the development, modeling, tuning, and optimization of CLCSs barely exploit the potential of artificial intelligence (AI). This paper explores novel opportunities and research directions in CLCS engineering, presenting potential designs and methodologies incorporating AI. Combining these opportunities and directions makes it evident that employing AI in developing and implementing CLCSs is indeed feasible. Integrating AI into CLCS development or AI directly within CLCSs can lead to a significant improvement in stakeholder confidence. Integrating AI in CLCSs raises the question: How can AI in CLCSs be trusted so that its promising capabilities can be used safely? One does not trust AI in CLCSs due to its unknowable nature caused by its extensive set of parameters that defy complete testing. Consequently, developers working on AI-based CLCSs must be able to rate the impact of the trainable parameters on the system accurately. By following this path, this paper highlights two key aspects as essential research directions towards safe AI-based CLCSs: (I) the identification and elimination of unproductive layers in artificial neural networks (ANNs) for reducing the number of trainable parameters without influencing the overall outcome, and (II) the utilization of the solution space of an ANN to define the safety-critical scenarios of an AI-based CLCS.
Recording of Low-Oxygen Stress Response Using Chlorophyll Fluorescence Kinetics in Apple Fruit
(2023)
Long-term storage of apples (Malus x domestica, Borkh.) is increasingly taking place under Dynamic Controlled Atmosphere (DCA). The oxygen level is lowered to ≤ 1 kPa O2 and the apples are stored just above the Lower Oxygen Limit (LOL). Low oxygen stress during controlled atmosphere storage can lead to fermentation in apples if oxygen levels are too low. Chlorophyll fluorescence can be used to detect low-oxygen stress at an early stage during storage. The currently available non-imaging fluorescence systems often use the minimal fluorescence (Fo) parameter. In contrast, the use of chlorophyll fluorescence kinetics is insufficiently described. Therefore, this study aimed to gain more knowledge about the response of chlorophyll fluorescence kinetics to low oxygen stress in apples using a fluorescence imaging system. The results show that the kinetic fluorescence curves differ under aerobic and fermentation conditions. The fermentative conditions initiated a decrease in fluorescence intensity upon application of the saturation pulses during exposure to actinic light. This result was made at 18 °C and 2 °C ambient temperatures. Interestingly, the kinetic curve changed at 2 °C before fermentation products accumulated in the apples. Non-photochemical quenching (NPQ) decreased under fermentation conditions in the dark phase after relaxation. Upon entering the dark relaxation phase after Kautsky induction, ɸPSII began to increase. Under atmospheric oxygen conditions, ɸPSII reached values of 0.81 to 0.76, while under fermentation, ɸPSII values ranged from 0.57 to 0.44.
Hyperhydricity (HH) is one of the most important physiological disorders that negatively affects various plant tissue culture techniques. The objective of this study was to characterize optical features to allow an automated detection of HH. For this purpose, HH was induced in two plant species, apple and Arabidopsis thaliana, and the severity was quantified based on visual scoring and determination of apoplastic liquid volume. The comparison between the HH score and the apoplastic liquid volume revealed a significant correlation, but different response dynamics. Corresponding leaf reflectance spectra were collected and different approaches of spectral analyses were evaluated for their ability to identify HH-specific wavelengths. Statistical analysis of raw spectra showed significantly lower reflection of hyperhydric leaves in the VIS, NIR and SWIR region. Application of the continuum removal hull method to raw spectra identified HH-specific absorption features over time and major absorption peaks at 980 nm, 1150 nm, 1400 nm, 1520 nm, 1780 nm and 1930 nm for the various conducted experiments. Machine learning (ML) model spot checking specified the support vector machine to be most suited for classification of hyperhydric explants, with a test accuracy of 85% outperforming traditional classification via vegetation index with 63% test accuracy and the other ML models tested. Investigations on the predictor importance revealed 1950 nm, 1445 nm in SWIR region and 415 nm in the VIS region to be most important for classification. The validity of the developed spectral classifier was tested on an available hyperspectral image acquisition in the SWIR-region.
Dairy farming has been the subject of public debate on animal welfare for a number of years now. Animal welfare discussions on dairy farming often include the demand for more nature connectedness in this area. This study focuses on the divergent perspectives of consumers and scientists on the importance of more nature connectedness for animal welfare strategies in German dairy farming. Within Europe, Germany is the main producer of cow’s milk and an important industry in many rural areas in Germany is dairy farming. The insights presented are based on qualitative interviews with dairy farming and livestock researchers from Germany and Austria. A key finding of this study is that we need to look more closely at the actual content of nature claims in animal welfare debates. The scientists interviewed tend to see idealized conditions in animal welfare discussions with images of nature which in fact seldom lead to improved conditions in dairy farming and, even then, only to a limited extent. The scientists interviewed rate calls for more nature connectedness in dairy farming from the nonagricultural public as anti-modern, complexity-reducing, and normative. Nevertheless, some of the scientists interviewed did have valuable insights into the nonagricultural public’s criticism of dairy farming practices. These scientists argued, however, that animal welfare needs to differentiate between nature connectedness and the innate needs of cattle when it comes to animal welfare strategies. An important conclusion of the study is that more discussion formats are needed to promote the exchange of ideas between different social groups attempting to understand animal welfare in dairy farming.
Iron deficiency is still widespread as a major health problem even in countries with adequate food supply. It mainly affects women but also vegans, vegetarians, and athletes and can lead to various clinical pictures. Biofortification of vitamin C-rich vegetables with iron may be one new approach to face this nutritional challenge. However, so far, little is known about the consumer acceptance of iron-biofortified vegetables, particularly in developed countries. To address this issue, a quantitative survey of 1000 consumers in Germany was conducted. The results showed that depending on the type of vegetable, between 54% and 79% of the respondents were interested in iron-biofortified vegetables. Regression analysis showed a relationship between product acceptance, gender, and area of residence. In addition, relationships were found between consumer preferences for enjoyment, sustainability, and naturalness. Compared to functional food and dietary supplements, 77% of respondents would prefer fresh iron-rich vegetables to improve their iron intake. For a market launch, those iron-rich vegetables appear especially promising, which can additionally be advertised with claims for being rich in vitamin C and cultivated in an environmentally friendly way. Consumers were willing to pay EUR 0.10 to EUR 0.20 more for the iron-biofortified vegetables.
Background
The current development of sensor technologies towards ever more cost-effective and powerful systems is steadily increasing the application of low-cost sensors in different horticultural sectors. In plant in vitro culture, as a fundamental technique for plant breeding and plant propagation, the majority of evaluation methods to describe the performance of these cultures are based on destructive approaches, limiting data to unique endpoint measurements. Therefore, a non-destructive phenotyping system capable of automated, continuous and objective quantification of in vitro plant traits is desirable.
Results
An automated low-cost multi-sensor system acquiring phenotypic data of plant in vitro cultures was developed and evaluated. Unique hardware and software components were selected to construct a xyz-scanning system with an adequate accuracy for consistent data acquisition. Relevant plant growth predictors, such as projected area of explants and average canopy height were determined employing multi-sensory imaging and various developmental processes could be monitored and documented. The validation of the RGB image segmentation pipeline using a random forest classifier revealed very strong correlation with manual pixel annotation. Depth imaging by a laser distance sensor of plant in vitro cultures enabled the description of the dynamic behavior of the average canopy height, the maximum plant height, but also the culture media height and volume. Projected plant area in depth data by RANSAC (random sample consensus) segmentation approach well matched the projected plant area by RGB image processing pipeline. In addition, a successful proof of concept for in situ spectral fluorescence monitoring was achieved and challenges of thermal imaging were documented. Potential use cases for the digital quantification of key performance parameters in research and commercial application are discussed.
Conclusion
The technical realization of “Phenomenon” allows phenotyping of plant in vitro cultures under highly challenging conditions and enables multi-sensory monitoring through closed vessels, ensuring the aseptic status of the cultures. Automated sensor application in plant tissue culture promises great potential for a non-destructive growth analysis enhancing commercial propagation as well as enabling research with novel digital parameters recorded over time.
Klimabäume scheinen in der Mitte der Gesellschaft angekommen zu sein. Zahlreiche Empfehlungen finden sich in Onlinemedien und stellen die fünf oder zehn besten Baumarten vor. Dabei gibt es Schnittmengen. Interessanterweise enthält das Sortiment weitgehend bekannte und auch heute schon verwendete Arten. Es steht eine breite Palette an zukunftsfähigen Klimabäumen zur Verfügung, die teilweise noch gar nicht beachtet werden. In zwei Teilen sollen bekannte und weniger bekannte Klimabäume bezüglich ihrer Verwendbarkeit im urbanen Raum, ihrer Herkunft und ihres Ausbreitungspotenzials diskutiert werden.
Primary Liver Cancers : Connecting the Dots of Cellular Studies and Epidemiology with Metabolomics
(2023)
Liver cancers are rising worldwide. Between molecular and epidemiological studies, a research gap has emerged which might be amenable to the technique of metabolomics. This review investigates the current understanding of liver cancer’s trends, etiology and its correlates with existing literature for hepatocellular carcinoma (HCC), cholangiocarcinoma (CCA) and hepatoblastoma (HB). Among additional factors, the literature reports dysfunction in the tricarboxylic acid metabolism, primarily for HB and HCC, and point mutations and signaling for CCA. All cases require further investigation of upstream and downstream events. All liver cancers reported dysfunction in the WNT/β-catenin and P13K/AKT/mTOR pathways as well as changes in FGFR. Metabolites of IHD1, IDH2, miRNA, purine, Q10, lipids, phosphatidylcholine, phosphatidylethanolamine, acylcarnitine, 2-HG and propionyl-CoA emerged as crucial and there was an attempt to elucidate the WNT/β-catenin and P13K/AKT/mTOR pathways metabolomically.
Aims and Objectives:
Preventive home visits are a low-threshold counselling and support approach. They have been reported to achieve heterogeneous effects. However, preventive home visits have the potential to reduce the risk of becoming dependent on long-term care. The aim of this study is to investigate the effect of preventive home visits as a nursing intervention on health-related quality of life of older people in a longitudinal survey and to develop recommendations for which target groups preventive home visits have the highest benefit. The sample consisted of 75 people, aged between 65 and 85, who were able to understand and speak German, had not yet been eligible for benefits from the long-term care insurance and lived in the municipality under study.
Methodological Design and Justification:
A quantitative longitudinal study in order to investigate the effects of preventive home visits.
Ethical Issues and Approval:
There were no ethical concerns. Accordingly, ethical approval was granted.
Research Methods, Results and Conclusions:
The health-related quality of life was recorded four times between 01/2017 and 08/2020 with the Short-Form- Health- Survey- 12 and analysed using descriptive statistics. Results reveal that the physical health status cannot be easily influenced over a short period of time. The main effect, however, is that preventive home visits have a significant positive effect on the mental health status. The main topics during the home visits were mobility, nutrition and social participation. Increased knowledge and motivation for preventive behaviour extended the autonomy of older people. Accordingly, preventive home visits can support a self-determined life in a familiar environment. The results of the present study show that preventive home visits as a nursing intervention in rural areas are successful. In Germany, preventive home visits have not yet been implemented on a regular basis. In order to do so, a general definition of the concept is needed. Preventive home visits should be officially included in the regular health care services in Germany.
While developing traffic-based cognitive enhancement technology (CET), such as bike accident prevention systems, it can be challenging to test and evaluate them properly. After all, the real-world scenario could endanger the subjects’ health and safety. Therefore, a simulator is needed, preferably one that is realistic yet low cost. This paper introduces a way to use the video game Grand Theft Auto V (GTA V) and its sophisticated traffic system as a base to create such a simulator, allowing for the safe and realistic testing of dangerous traffic situations involving cyclists, cars, and trucks. The open world of GTA V, which can be explored on foot and via various vehicles, serves as an immersive stand-in for the real world. Custom modification scripts of the game give the researchers control over the experiment scenario and the output data to be evaluated. An off-the-shelf bicycle equipped with three sensors serves as a realistic input device for the subject’s movement direction and speed. The simulator was used to test two early-stage CET concepts enabling cyclists to sense dangerous traffic situations, such as trucks approaching from behind the cyclist. Thus, this paper also presents the user evaluation of the cycling simulator and the CET used by the subjects to sense dangerous traffic situations. With the knowledge of the first iteration of the user-centered design (UCD) process, this paper concludes by naming improvements for the cycling simulator and discussing further research directions for CET that enable users to sense dangerous situations better.
Semi-natural grasslands (SNGs) are an essential part of European cultural landscapes. They are an important habitat for many animal and plant species and offer a variety of ecological functions. Diverse plant communities have evolved over time depending on environmental and management factors in grasslands. These different plant communities offer multiple ecosystem services and also have an effect on the forage value of fodder for domestic livestock. However, with increasing intensification in agriculture and the loss of SNGs, the biodiversity of grasslands continues to decline. In this paper, we present a method to spatially classify plant communities in grasslands in order to identify and map plant communities and weed species that occur in a semi-natural meadow. For this, high-resolution multispectral remote sensing data were captured by an unmanned aerial vehicle (UAV) in regular intervals and classified by a convolutional neural network (CNN). As the study area, a heterogeneous semi-natural hay meadow with first- and second-growth vegetation was chosen. Botanical relevés of fixed plots were used as ground truth and independent test data. Accuracies up to 88% on these independent test data were achieved, showing the great potential of the usage of CNNs for plant community mapping in high-resolution UAV data for ecological and agricultural applications.
Dynamic Controlled Atmosphere-Chlorophyll Fluorescence storage (DCA-CF) uses a fluorescence-based measurement method to detect fermentation in apples (Malus × domestica BORKH.) caused by low-oxygen levels at an early stage. In recent years, it has been observed that individual apples of the same variety and origin can exhibit different fermentation behavior when stored under completely identical conditions. The causes of the different fermentation behavior must be found in order to be able to use DCA storage optimally. This study aimed to find the causes of the different fermentation behaviors of individual apples. Our results show that fruit ripeness can affect the lower oxygen limit (LOL), especially immediately after harvest, when the starch degradation in the fruit is not yet complete. A significant increase in the LOL was observed in ‘Elstar’ (2020: 0.3 kPa, 0.6 kPa, 0.9 kPa; 2021: 0.3 kPa, 0.4 kPa, 0.6 kPa). ‘Braeburn’ also exhibited this behavior regarding the LOL at a lower level. The LOL could not be identified for some of the fruit (varying from 12.5% to 41.7% of the examined apples) previously stored in Ultra Low Oxygen (ULO) storage for 4 months. Also, the chlorophyll content in the apple skin influences the fluorescence measurement method. Within 2 weeks, the chlorophyll content in the apple skin was halved. If the chlorophyll content drops, the reliability of the fluorescence measurement also decreases. It turned out that apples with an Fv/Fm < 0.7 were unsuitable for valid LOL identification.
Purpose
The purpose of this paper is to distinguish different types of sustainable digital entrepreneurs (SDEs) and explore their approaches toward enhancing organizational resilience.
Design/methodology/approach
Investigation of entrepreneur characteristics using Grounded Theory methodology; 12 semi-structured telephone interviews with (owner-)managers of digital-resilient small and medium-sized enterprises (SMEs) and start-ups in Germany; adaptation of a sustainability-digitalization-matrix for initial clustering; investigation of reoccurring patterns (within and between clusters) through variable-oriented content analysis; application of the capability-based conceptualization of organizational resilience for synthesis and extension.
Findings
First, the authors present a new typology of SDEs, including descriptions of the four main types (Process-Oriented System Thinker, Unconventional Strategist, Dynamic Visionary and Success-Oriented Opportunist). Second, the authors propose a conceptual framework with six success factors of organizational resilience. The framework accentuates the influence of SDEs on organizational culture and the macro-environment.
Practical implications
Digital sustainability and resilience are emerging management principles. The insights gained will allow (future) entrepreneurs to perform a self-assessment and replicate approaches toward enhancing SME resilience; for example, governing the co-creation of an organizational culture with a strong integrative view on sustainability and digitalization.
Originality/value
SMEs are characterized by high vulnerability and a reactive response to the disruptions caused by sustainability crises and digitalization. Blending sustainable and digital entrepreneurship at a micro-level, the authors identified the success factors underpinning organizational resilience that are associated with the characteristics of four types of SDEs.
In recent years, the issue of land consumption or land use has become increasingly important in many areas of our society. Logistics processes in particular take up a lot of space and have a significant impact on the environment. The question is how this use of land can be optimised. Based on a systematic literature review and interviews with experts in the period between May 2021 and July 2021, this paper presents indicators that constitute or influence space-efficient logistics in the context of cooperation. The results show that in addition to the established cooperation characteristics, there are other indicators that are directly related to land use. In the logistics sector, there is strong competitive pressure and, as a result, little trust between companies. It has been shown that with the help of a neutral moderator, the gap between trusting, land-efficient cooperation and one’s own entrepreneurial interests can be narrowed, and cooperation can be profitable for all participants. In addition, digitisation actually does not seem to be sufficient to meet the information needs of a cooperation. The exchange of information not only serves to automate processes, but also makes cooperation more transparent. It shows that legal and municipal requirements need to be developed. It also becomes clear that the indicators have a mutual influence on each other and cannot be considered in isolation when it comes to the actual implementation of a cooperation. By increasing the efficiency of cooperative processes and value creation, it offers the opportunity to make land use more sustainable.
In the race against climate change, small and medium-sized enterprises (SMEs) play a fundamental role. To clarify the contribution of corporate culture to SMEs' emission reduction, three perspectives can be useful: corporate culture as driver and barrier, current and planned corporate culture development actions, and the corporate culture profile as an outcome. As the first application of the extended Belief-Action-Outcome framework, this single case study exemplifies the role of corporate culture in an SME from the steel construction and manufacturing sector in Germany. The investigated SME has achieved emission reduction while increasing its revenue and is an early adopter of sustainable and digital development. The rich insights from an employee survey, semi-structured interviews, observation, and document analysis allowed us to outline an informed approach toward corporate culture development that emphasizes vision development of the desired corporate culture and the role of information systems for promoting emission reduction.
In view of the rapid depletion of natural resources and the associated overloading of the biological ecosystem, the concept of circular business models (CBMs) is increasingly discussed in the literature as well as in business practice. CBMs have the potential to significantly reduce the demand for natural resources. Despite their increasing relevance, the diffusion of CBMs in business practice is largely unexplored. Consequently, this article investigates the extent to which CBMs have already been adopted by large German companies. To answer this question, the annual and sustainability reports of the members of the DAX40 are analyzed for the presence of five specific types of CBMs. Data was gathered for the years 2015 and 2020 in order to describe the development over time. The results show an increasing prevalence of CBMs in the DAX companies. In addition, it is noticeable that CBM types that serve to close material cycles are implemented more frequently than those that decelerate material cycles. In particular Sharing Platforms and Product as a Service stand out due to comparatively low adoption. Potential reasons for these findings are discussed and managerial as well as policy implications suggested.
Die Verknappung der Ressource Fläche sowie der Umgang mit genutzten Flächen haben dazu beigetragen, dass in Deutschland zukünftig Landdegradationen verhindert werden sollen. Insbesondere die Logistikbranche trägt aufgrund ihres hohen Flächenverbrauchs zu dieser Entwicklung bei. Welche zukünftigen Möglichkeiten und Risiken der Land und Bodennutzung bestehen für den Logistiksektor?
Grasslands are ubiquitous globally, and their conservation and restoration are critical to combat both the biodiversity and climate crises. There is increasing interest in implementing effective multifunctional grassland restoration to restore biodiversity concomitant with above- and belowground carbon sequestration, delivery of carbon credits and/or integration with land dedicated to solar panels. Other common multifunctional restoration considerations include improved forage value, erosion control, water management, pollinator services, and wildlife habitat provisioning. In addition, many grasslands are global biodiversity hotspots. Nonetheless, relative to their impact, and as compared to forests, the importance of preservation, conservation, and restoration of grasslands has been widely overlooked due to their subtle physiognomy and underappreciated contributions to human and planetary well-being. Ultimately, the global success of carbon sequestration will depend on more complete and effective grassland ecosystem restoration. In this review, supported by examples from across the Western world, we call for more strenuous and unified development of best practices for grassland restoration in three areas of concern: initial site conditions and site preparation; implementation of restoration measures and management; and social context and sustainability. For each area, we identify the primary challenges to grassland restoration and highlight case studies with proven results to derive successful and generalizable solutions.
Advances in high-throughput DNA sequencing have propelled research into the human microbiome and its link to metabolic health. We explore microbiome analysis methods, specifically emphasizing metabolomics, how dietary choices impact the production of microbial metabolites, providing an overview of studies examining the connection between enterotypes and diet, and thus, improvement of personalized dietary recommendations. Acetate, propionate, and butyrate constitute more than 95% of the collective pool of short-chain fatty acids. Conflicting data on acetate’s effects may result from its dynamic signaling, which can vary depending on physiological conditions and metabolic phenotypes. Human studies suggest that propionate has overall anti-obesity effects due to its well-documented chemistry, cellular signaling mechanisms, and various clinical benefits. Butyrate, similar to propionate, has the ability to reduce obesity by stimulating the release of appetite-suppressing hormones and promoting the synthesis of leptin. Tryptophan affects systemic hormone secretion, with indole stimulating the release of GLP-1, which impacts insulin secretion, appetite suppression, and gastric emptying. Bile acids, synthesized from cholesterol in the liver and subsequently modified by gut bacteria, play an essential role in the digestion and absorption of dietary fats and fat-soluble vitamins, but they also interact directly with intestinal microbiota and their metabolites. One study using statistical methods identified primarily two groupings of enterotypes Bacteroides and Ruminococcus. The Prevotella-dominated enterotype, P-type, in humans correlates with vegetarians, high-fiber and carbohydrate-rich diets, and traditional diets. Conversely, individuals who consume diets rich in animal fats and proteins, typical in Western-style diets, often exhibit the Bacteroides-dominated, B-type, enterotype. The P-type showcases efficient hydrolytic enzymes for plant fiber degradation but has limited lipid and protein fermentation capacity. Conversely, the B-type features specialized enzymes tailored for the degradation of animal-derived carbohydrates and proteins, showcasing an enhanced saccharolytic and proteolytic potential. Generally, models excel at predictions but often struggle to fully elucidate why certain substances yield varied responses. These studies provide valuable insights into the potential for personalized dietary recommendations based on enterotypes

HRM processes are increasingly AI-driven, and HRM supports the general digital transformation of companies’ viable competitiveness. This paper points out possible positive and negative effects on HRM, workplaces, and workersorganizations along the HR processes and its potential for competitive advantage in regard to managerial decisions on AI implementation regarding augmentation and automation of work.
A systematic literature review that includes 62 international journals across different disciplines and contains top-tier academic and German practitioner journals was conducted. The literature analysis applies the resource-based view (RBV) as a lens through which to explore AI-driven HRM as a potential source of organizational capabilities.
The analysis shows four ambiguities for AI-driven HRM that might support sustainable company development or might prevent AI application: job design, transparency, performance and data ambiguity. A limited scholarly discussion with very few empirical studies can be stated. To date, research has mainly focused on HRM in general, recruiting, and HR analytics in particular.
The four ambiguities’ context-specific potential for capability building in firms is indicated, and research avenues are developed.
This paper critically explores AI-driven HRM and structures context-specific potential for capability building along four ambiguities that must be addressed by HRM to strategically contribute to an organization’s competitive advantage.
Hintergrund
Demografisch bedingt wird sich die Anzahl pflegebedürftiger Menschen weiter erhöhen. Tragende Säule der pflegerischen Versorgung sind ihre Angehörigen, die den Großteil der Pflegeaufgaben übernehmen. Dies hat jedoch oftmals Auswirkungen auf ihre eigene Gesundheit und ihr Wohlbefinden.
Methodisches Vorgehen
Mit dem Fragebogen zur Angehörigenresilienz und -belastung (FARBE) liegt ein Instrument vor, um sowohl die Resilienz als auch Belastung pflegender Angehöriger zu ermitteln. Der Fragebogen wurde im Rahmen der Pflegestudie des VdK-Sozialverbands genutzt und von 12.475 Angehörigen komplett ausgefüllt. Durch eine multiple lineare Regression wurden Einflüsse und ihre Wirkstärke auf die Resilienz und Belastung analysiert.
Ergebnisse
Angehörige von Menschen mit Demenz, Depression oder hohem Pflegegrad weisen eine stärkere Belastung auf. Demenz und Depression mindern zudem die Resilienz. Positiv wirkt sich die soziale Unterstützung aus. Ebenso bedingt ein höheres Alter eine stärkere Resilienz.
Schlussfolgerungen
Im Ergebnis dieser Arbeit gelang eine Identifikation von relevanten Einflussfaktoren. Dies ermöglicht, Unterstützungs- und Entlastungsangebote auf ihre Anwendung und Wirksamkeit zu überprüfen. Besondere Bedeutung haben Unterstützungsangebote für Angehörige von Menschen mit Demenz, Depression und/oder höheren Pflegegraden. Stressreduzierende Maßnahmen und das Bilden sozialer Netzwerke für Angehörige können weitere Maßnahmen zur Stärkung der Resilienz und Abschwächung von Belastung sein.
Die Autoren präsentieren einen innovativen Ansatz für Circular Economy (CE)-Strategien mit hohem Umweltpotenzial. Dieser Ansatz betont Verweigerung, Umdenken und Reduzieren, indem die Perspektive vom Verbraucher auf soziale Praktiken verschoben wird. Dabei wird Suffizienz als Schlüsselkonzept eingeführt, das entscheidend ist, um Umweltbelastungen durch CE zu reduzieren und die Transformation des Produktions- und Konsumsystems zu fördern. Die Autoren betonen, dass nachhaltige Kreislaufwirtschaft ohne Suffizienz nicht möglich ist.
Die Studie berichtet über einen Fall, in dem die Über-Verfügbarkeit durch das Konzept der Genügsamkeit ersetzt wurde. Die Autoren beobachten, wie Suffizienz in die Lebensstile der Teilnehmer integriert wird, insbesondere durch einen Farmboxing-Ansatz. Obwohl die Verallgemeinerung des Falls begrenzt ist, zeigt die Studie das Potenzial niedrigschwelliger Einführungen von Suffizienz, wie beispielsweise öffentlicher Raum für gärtnerische Aktivitäten.
Die Autoren betonen jedoch die Notwendigkeit weiterer empirischer Arbeit, um die Bedeutung von Suffizienz in verschiedenen sozialen Praktiken zu verstehen. Sie schlagen vor, dass der Zeitpunkt für solche Forschungen günstig ist, angesichts aktueller globaler Entwicklungen und der steigenden Nachfrage nach Strategien zur Ressourcenverringerung.
Die Studie identifiziert Herausforderungen, darunter unklare Faktoren, die nicht berücksichtigt wurden, wie die Rolle des sozialen Umfelds und die Übertragbarkeit der Ergebnisse auf andere Lebensbereiche. Die Autoren planen bereits eine Folgestudie mit quantitativen und qualitativen Analysen sowie Lebenszyklusanalysen.
Abschließend schlagen die Autoren vor, klare Definitionen für Wiederverwendung, Umdenken und Reduzierung zu entwickeln, basierend auf empirischen Daten und Beispielen sozialer Praktiken. Sie fordern auch dazu auf, Theorien sozialer Praktiken auf andere CE-Strategien anzuwenden, da soziale Praktiken nicht auf privaten Konsum beschränkt sind.
The BBI is a first step toward putting biodiversity conservation into practice in the OHC context. The results are consistent with studies related to nutrition However, the results also show that there is room for improvement and that there are further areas to be addressed. It is also clear that commercial kitchens currently have only limited room for maneuver. If OHC is to become more biodiversity-friendly, greater transparency is needed in terms of origin labels and species/variety identifiers, and a wide range of options will also be required in terms of procurement. That being the case, it is essential to focus on the entire value chain. Furthermore, in addition to the initial recommendations, much more knowledge is required about the impacts of farming methods and heritage varieties and species, as well as about the use of fish, other marine animals and game meat. In principle, however, the BBI can already be implemented in commercial kitchens by identifying recipe optimizations that kitchens can feasibly implement, that align with their budgets, and that maintain acceptance among patrons. In addition, this approach has the potential to be integrated into the assessment framework of the NAHGAST calculator, making it readily accessible and free for OHC facilities to use. In the OHC context in particular, this could be leveraged to drive sustainable change in the food system.
Leftovers lovers vs. haters: A latent class analysis on dinner leftover management behaviours
(2023)
Die Studie untersucht die Heterogenität im Umgang mit Speiseresten in Haushalten, insbesondere unter Verwendung von Mahlzeitensets mit angepassten Portions- und Zutatengrößen. Durch eine latenten Klassenanalyse werden Verbrauchersegmente identifiziert, wobei die positive Einstellung zu Essensresten und bewusster Umgang damit untersucht werden. Die Studie analysiert auch die Auswirkungen von Emotionen, persönlichen Normen, Intentionen und Essensbeschaffungsroutinen auf die Zugehörigkeit zu einem Resteverwertungssegment. Daten von 868 Haushalten aus sechs Ländern zeigen fünf Verbrauchersegmente mit Unterschieden in der Menge der Essensreste. Mahlzeitensets haben heterogene Auswirkungen, indem sie in einigen Segmenten die Menge der Essensreste verringern, in anderen jedoch nicht. Die Ergebnisse bieten neue Erkenntnisse über die Vielfalt im Umgang mit Speiseresten und liefern Implikationen für Theorie und Politik zur Reduzierung von Lebensmittelverschwendung im Haushalt.
In a protein reduction feeding trial (Study 1) on a commercial broiler farm in northern Germany, it was attempted to be shown that research results from station tests on protein reduction can be transferred to agricultural practice. In a second study, the limits of the N reduction were tested in a research facility. In Study 1, commercial standard feeds were fed to the control group (variant 1:210,000 animals; n = 5 barns). In the test group (variant 2:210,000 animals; n = 5 barns), the weighted mean crude protein (CP) content was moderately reduced by 0.3%. The nitrogen reduction in the feed did not affect performance (feed intake (FA), daily gain (DG), feed conversion (FCR)), but nitrogen conversion rate increased from approx. 61% to approx. 63%. The solid litter weight was reduced by 12% and nitrogen excretion by 9% (p < 0.05). Significantly healthier footpads were due to lower water intake (−4%; p < 0.05) and a numerically drier bedding. In Study 2, responses of treatments (1250 broiler per variant; n = 5) showed that sharper N-lowering (−1.5% CP; weighted average) did not impair performance either, but N-conversion improved and N-excretions decreased significantly. Converted to a protein reduction of one percentage point, the N excretions were able to be reduced by 22% in Study 1 and 18% in Study 2. Feeding trials in the commercial sector, such as the present Study 1, should convince feed mills and farmers to allow the latest scientific results to be used directly and comprehensively in commercial ration design.
Duckweed is gaining attention in animal nutrition and is considered as a potential alternative protein source for broiler chickens. In order to evaluate the nutritional value of duckweed, three individual batches were investigated. They consisted of a mixture of Lemna minuta and Lemna minor (A, 17.5% crude protein), Spirodela polyrhiza (B, 24.6% crude protein) and Lemna obscura (C, 37.0% crude protein). Treatment diets contained 50% batch A, 50% batch B, and 25, 50 and 75% of batch C. All diets were fed to broiler chickens (Ross 308) from an age of 21 to 27 days. Diets with a share of 50 and 75% of batch C led to decreased feed intake (109.3 and 74.9 g/day, respectively) compared to the control. Standardized ileal digestibility of crude protein and amino acids differed significantly between duckweed batches, at values for methionine between 49.9 and 90.4%. For all amino acids, batch A consistently had the lowest and batch C the highest digestibility. Batches had different tannin contents of 2943, 2890 and 303 mg/kg for batches A, B and C, respectively. The apparent ileal digestibility of phosphorus differed significantly between all batches (50.8–78.9%). Duckweed can be used as a protein feed for broiler chickens. However, a defined and stable biomass composition optimized for the requirements of broiler chickens is needed.
The present study aims to compare the effects of maternal and offspring treatment with 25-hydroxycholecalciferol (25-OHD3) and vitamin D3 on vitamin D status, mineral homoeostasis, bone metabolism and locomotion in the offspring. Either vitamin D3 (50 μg/kg diet) or 25-OHD3 (50 μg/kg diet) was supplemented to the gestation and lactation diets of 49 multiparous sows and/or to the diets of their growing offspring. Treatment of the sows did not affect plasma concentrations of 25-OHD3 of the offspring. Pigs fed 25-OHD3 had higher plasma concentrations of 25-OHD3 than pigs that received vitamin D3 during rearing and fattening. However, neither plasma concentrations of calcium, phosphate and bone markers during the observation period nor bone ash and bone mineral density at slaughter were clearly affected by the treatment. Maternal and offspring treatment with 25-OHD3 instead of vitamin D3 resulted in a slight reduction in the prevalence of leg swelling. In addition, more pigs walked with even steps and normal stride length. Further studies are needed to test whether the slight effects observed in the present experiment are reproducible and of relevance for animal health and welfare. In that case, the underlying mechanisms should be revealed in order to take advantage of potentially beneficial influences especially under certain feeding regimes.
Lahmheiten bilden bei Sauen und wachsenden Schweinen ein ernstzunehmendes Gesundheits- und Tierwohlproblem. Die Studie zeigte, dass der diätetische Einsatz von 25-Hydroxycholecalciferol im Austausch zum Vitamin D3 zu einer Reduktion von Bewegungsproblemen bei Sauen und wachsenden Schweinen geführt hat.

Der vorliegende Aufsatz untersucht den Einfluss körperorientierter Influencer-Kommunikation auf die Rezipienten. Hierfür wurde im Rahmen einer Bachelorarbeit ergründet, inwiefern die Inhalte zu Verhaltensänderungen führen und wie sie sich auf die Körperwahrnehmung der Rezipienten auswirken. Die Forschung fußt auf der Theorie des sozialen Vergleichs. In einer quantitativen Inhaltsanalyse wurde kategorisiert, welche körperorientierten Influencer-Inhalte die Probandinnen sehen. Auf dieser Grundlage bauen die anschließenden Leitfadeninterviews auf. Sie wurden mithilfe einer qualitativen Inhaltsanalyse ausgewertet. Die Erkenntnisse belegen Teile der Theorie des sozialen Vergleichs. Auch stimmen sie mit aktuellen Forschungsergebnissen überein, die den Einfluss körperorientierter Influencer-Kommunikation untersuchen. Die Probandinnen erfahren überwiegend aufwärtsgerichtete, soziale Vergleiche mit den Influencer-Inhalten. Sowohl bei Inhalten, die das geltende Schönheitsideal unterstreichen, als auch bei solchen, die Selbstliebe und Akzeptanz äußerlicher Makel kommunizieren. Die Inhalte beeinflussen Verhaltensweisen der Rezipienten, besonders hinsichtlich sportlicher Aktivitäten sowie dem Umgang mit dem eigenen Körper. Der Einfluss variiert von einer positiven bis zu einer deutlich negativen Wirkung. Abhängig ist dies von Inhaltsform und zugehöriger Vergleichsrichtung: Stark aufwärtsgerichtete Vergleiche haben einen deutlich negativeren Einfluss auf die Rezipienten, als nur leicht aufwärtsgerichtete oder gleichgestellte soziale Vergleiche. Diese extremen Aufwärtsvergleiche werden besonders von Influencer-Inhalten hervorgerufen, die das geltende Schönheitsideal verkörpern. Für die Praxis bedeuten die Ergebnisse, dass körperorientierte Kommunikation deutlich bewusster und mit Blick auf das Wohlbefinden der Rezipienten geschehen muss. Auch geben sie Anlass zu weiterer Forschung: Besonders interessant wäre es, den Abwärtsvergleich zu Influencern eingehender zu untersuchen.
In der digitalisierten Arbeitswelt ermöglichen neue und flexible Informations- und Kommunikationstechnologien (IKT) eine raum- und zeitunabhängige Erreichbarkeit (Albers, 2018). Während die „ständige“ Erreichbarkeit öffentlich kontrovers diskutiert wird, zeigt sich im Bereich des Kommunikationsmanagements, insbesondere hinsichtlich der Untersuchung von Agenturen, eine Forschungslücke (Röttger & Zielmann, 2009). Dieser Beitrag knüpft daran an und liefert empirische sowie praxisnahe Erkenntnisse zur arbeitsbezogenen erweiterten Erreichbarkeit. Mit dem Fokus auf Mitarbeitende in Kommunikationsagenturen wurde untersucht, wie ihre Erreichbarkeit ausfällt und welche Gestaltungsansätze sich im Arbeitskontext daraus ableiten. Zu ihrer Beantwortung wurden qualitative, leitfadengestützte Interviews mit Vollzeitbeschäftigten (n= 10) aus mittelgroßen Agenturen (Größe: 20 bis 50 Beschäftigte, n= 5) durchgeführt und ausgewertet. Die Interviewstudie analysiert Ausmaß, Ursachen, individuelle und betriebliche Umgangsweisen sowie darauf aufbauende Handlungsansätze. Die Ergebnisse verdeutlichen zwei Aspekte der erweiterten Erreichbarkeit in Agenturen: Individualität und Vielfalt. Innerhalb der Untersuchung kann verdeutlicht werden, dass die Erreichbarkeit auf einer Kombination vielfältiger Ursachen beruht. Für die Gestaltung der Erreichbarkeit leiten sich daraus relevante Implikationen ab: Statt verbindlicher Vorschriften sollte ein selbstbestimmtes, flexibles Arbeiten im Vordergrund stehen.
Der vorliegende Aufsatz setzt sich mit dem Hostile-Media-Phänomen auseinander, nach welchem Personen, die eine starke Einstellung bei einem Thema aufweisen, die mediale Berichterstattung dazu als tendenziell konträr zu ihrer eigenen Meinung wahrnehmen (Vallone et al., 1985). Der Effekt wird durch Merkmale der Quellenangabe verstärkt, die Gruppenzugehörigkeiten des Kommunikators suggerieren (Ariyanto et al., 2007; Arpan & Raney, 2003; Gunther & Liebhart, 2006; Gunther et al., 2016; Kim & Billings, 2017; Reid, 2012). Nun wird für diese Arbeit vermutet, dass das Alter – als natürliches Merkmal – in bestimmten Kontexten als Heuristik für die ideologische Perspektive des Kommunikators fungiert. Entsprechend, so die Annahme, werden junge Befürworter bei dem Thema „Fridays for Future“ einen jungen Kommunikator mit der In-Group und einen alten Kommunikator mit der Out-Group assoziieren. Die Zuordnung des Kommunikators zu der In-Group resultiert demnach in einer Assimilation mit den Inhalten. Wird der Artikel hingegen der Out-Group zugerechnet, sollten die Inhalte abgelehnt beziehungsweise als feindlich verzerrt wahrgenommen werden. In einer experimentellen Studie wurden 108 Studierende um die Einschätzung zu einem Kommentar über „Fridays for Future“ gebeten. Der ausgewogene Text wurde entweder einem vermeintlich jungen oder alten Autor zugeschrieben. Dem Kommentar in der Version ALT wurde von den jungen Befürwortern erwartungsgemäß weniger zugestimmt als dem identischen Inhalt in der Version JUNG. Allerdings konnten keine signifikanten Unterschiede zwischen den beiden Versionen bei der Einschätzung der Ausgewogenheit des Artikels festgestellt werden. Diese Arbeit wirft einen neuen Blickwinkel auf potenziell relevante Merkmale der Quellenangabe bei der Entstehung von Hostile-Media-Effekten und gibt damit Anreize für zukünftige Forschung in diesem Bereich.
Die vorliegende Studie beschäftigt sich mit dem Einfluss der Corona-Pandemie auf die Interne Unternehmenskommunikation in Kliniken und deren interne Positionierung. Dafür wurden sechs Expert:inneninterviews mit Verantwortlichen der Internen Unternehmenskommunikation in Kliniken geführt, die anschließend durch eine qualitative Inhaltsanalyse ausgewertet wurden. Die Untersuchung zeigt, dass die Corona-Pandemie aufgrund ihrer Kriseneigenschaften eine Chance für die Bedeutung der Internen Unternehmenskommunikation in den befragten Kliniken darstellt. Dazu stellt sich heraus, dass die Krise die hierarchische Einbindung, die finanziellen Ressourcen und die interne Akzeptanz der internen Kommunikationsverantwortlichen positiv beeinflusst. Auch wenn die Pandemie nicht auf alle Aspekte der internen Positionierung einwirkt, lässt sie sich als eine Chance für die Neupositionierung der Internen Unternehmenskommunikation identifizieren. Gerade mit ihrem Einfluss auf die interne Bedeutungswahrnehmung gelingt es der Krise, an einer wichtigen Stellschraube für die Verbesserung der internen Positionierung zu drehen.
Dieser Artikel setzt sich anhand eines Beispiels mit der Frage auseinander, welchen Beitrag soziale Medien für die Pflege des kollektiven Gedächtnisses leisten und welche Risiken mit dem Einsatz von sozialen Medien in der Erinnerungskultur einhergehen. Anhand des Instagram-Projekts @ichbinsophiescholl vom SWR und BR wurden die Vor- und Nachteile von sozialen Medien unter Berücksichtigung von wissenschaftlichen Publikationen diskutiert. Zehn Monate lang, von Mai 2021 bis Februar 2022, konnten Instagram-Nutzer das Leben einer fiktiven Sophie Scholl verfolgen. Durch Storytelling und die Kombination aus fiktiven und realen Inhalten versuchten die Projektverantwortlichen, die Geschichte der Widerstandskämpferin auf dem Instagram-Kanal @ichbinsophiescholl zu erzählen. Aufgrund von fehlenden Quellenangaben und dem Verzicht darauf, fiktive Inhalte kenntlich zu machen, wurde das Projekt kritisiert. Der Vorwurf, dass das Projekt ein falsches Bild von Sophie Scholl erschafft, wurde laut. Damit trifft die Sorge, dass in sozialen Medien nicht immer zwischen anerkannter Geschichtsdarstellung, Fiktion oder Unwahrheit unterschieden werden kann, auch auf @ichbinsophiescholl zu. Es ist noch ein langer Weg, bis solche Projekte einen wertvollen Beitrag zum Erhalt der Erinnerungskultur beitragen können, ohne Gefahr zu laufen, Geschichte falsch oder unangemessen darzustellen. Um herauszufinden, wie Erinnerungsprojekte aufgebaut sein müssen, um als sinnvoller Beitrag zum kollektiven Gedächtnis wahrgenommen zu werden und eine Balance zwischen dem aktuellen Zeitgeist und einer trivialisierenden Darstellung zu finden, werden weitere wissenschaftliche Untersuchungen benötigt.
In the context of the ongoing digitization of interdisciplinary subjects, the need for digital literacy is increasing in all areas of everyday life. Furthermore, communication between science and society is facing new challenges, not least since the COVID-19 pandemic. In order to deal with these challenges and to provide target-oriented online teaching, new educational concepts for the transfer of knowledge to society are necessary. In the transfer project “Zukunftslabor Gesundheit” (ZLG), a didactic concept for the creation of E-Learning classes was developed. A key factor for the didactic concept is addressing heterogeneous target groups to reach the broadest possible spectrum of participants. The concept has already been used for the creation of the first ZLG E-Learning courses. This article outlines the central elements of the developed didactic concept and addresses the creation of the ZLG courses. The courses created so far appeal to different target groups and convey diverse types of knowledge at different levels of difficulty.
Das Unternehmen "100 Worte Sprachanalyse" hat 2021 den "HR Startup Award" erhalten, der federführend vom Bundesverband der Personalmanager (BPM) verliehen wird. Überzeugt hat 100 Worte "mit dem Versprechen, den unbewussten Gender-Bias in Stellenanzeigen zu reduzieren und unterschiedliche Grundmotive von Bewerbergruppen zu erfassen", so die Initiatoren. Doch es bestehen berechtigte Zweifel daran, dass die Software dieses Versprechen einlösen kann.
Power consumption has become a major design constraint, especially for battery-powered embedded systems. However, the impact of software applications is typically considered in later phases, where both software and hardware parts are close to their finalization. Power-related issues must be detected in early stages to keep the development costs low, satisfy time-to-market, and avoid cost-intensive redesign loops. Moreover, the variety of hardware components, architectures, and communication interfaces make the development of embedded software more challenging. To manage the complexity of software applications, approaches such as model-driven development (MDD) may be used. This article proposes a power-estimation approach in MDD for software application models in early development phases. A unified modeling language (UML) profile is introduced to model power-related properties of hardware components. To determine the impact of software applications, we defined two analysis methods using simulation data and a novel in-the-loop concept. Both methods may be applied at different development stages to determine an energy trace, describing the energy-related behavior of the system. A novel definition of energy bugs is provided to describe power-related misbehavior. We apply our approach to a sensor node example, demonstrate an energy bug detection, and compare the runtime and accuracy of the analysis methods.
Who is more eager to use Gamification in Economic Disciplines? Comparison of Students and Educators
(2022)
Background: In this paper, the focus is on the application of digital and mobile technologies as supporting tools for the implementation of gamification in the field of education of future economists. Objectives: The paper's main objective is to explore whether educators and students are motivated and willing to apply additional technologies as main gamification components in their work and education. Moreover, the paper aims to assess how their more comprehensive application affects the quality of teaching, work flexibility, new learning opportunities, and outcomes. Methods/Approach: The survey method was used to collect answers from educators and students primarily interested in accounting, finance, trade and tourism from higher and secondary education institutions in Croatia, Poland, Serbia and Germany. Afterwards, the responses were compared using statistical methods. Results: Research results confirm that educators and students are willing to use gamification in teaching. Still, they also expressed the need for better administrative support in using particular e-learning tools. Surprisingly, educators are more eager to use gamification in their work than students. Conclusions: The study's general conclusion is that educators and students are both aware of the advantages of using e-learning tools provided through digital and mobile technologies and are eager to implement more gamification in the teaching process. However, continuous education in applying new digital technologies is needed on both sides.
Background
The aim of this qualitative study was to identify a practice level model that could explain a sustained change in nutritional behavior.
Methods
The study used three data inputs from four interviewees, one merged input from a married couple, as narrative interviews. The interviews were analyzed using grounded theory.
Results
Coexistence of a certain suffering and a triggering episode lead to the decision to change nutritional life-style by all interviewed. Maintenance of the self-determined newly learned nutritional behavior was supported by subject-related intrinsic motivation, the ability to reflect, and a low expectation of success from the behavioral change. Environment-related factors were identified as support from life-partner and peers. Subjects reported that the sustained nutritional behavior change impacted their holistic health through subject-perceived improved life quality, increase in the number of social contacts, and a change in personal attitudes and perception. The analysis remains limited, and at best hypothesis generating, in that only three data inputs from four interviewees were used.
Conclusion
In this hypothesis-generating narrative interview study of four study subjects, volition, personal decision making, and long-term motivation (though not external determination) seemed to sustain a change in newly learned nutritional behavior.

Hintergrund
Schmerz hat einen entscheidenden Einfluss auf die humane Lebensqualität. Allein eine Wissensvergrößerung über neurobiologische Vorgänge kann das subjektive Schmerzempfinden sowie psychometrische Variablen positiv beeinflussen. Es gibt verschiedene Formen der präoperativen Patientenedukation, welche u. a. zum Ziel haben, den postoperativen Schmerz zu erklären. Laut der aktuellen Literatur liegt einer präoperativen biomedizinischen Edukation eine geringe Evidenz zugrunde. Sie kann das präoperative Angst- und Stresslevel der Patienten steigern, was sich negativ auf das postoperative Outcome auswirkt. Im Gegensatz zur biomedizinischen Edukation betrachtet das neurobiologische Verständnis den postoperativen Schmerz unter den Gesichtspunkten der Plastizität des Nervensystems und bezieht Sensibilisierungsprozesse im zentralen und peripheren Nervensystem mit ein.
Ziel
Systematische Untersuchung von Kurz- und Langzeiteffekten einer neurobiologischen (Schmerz‑)Edukation bei Patienten vor einer Wirbelsäulenoperation
Material und Methoden
Bei der Literaturrecherche wurde nach dem PI(C)O(Population Intervention Comparison Outcome)‑Schema in den medizinischen Datenbanken gesucht. 83 Artikel kamen in die engere Auswahl. Entsprechend den Ein- und Ausschlusskriterien konnten letztendlich neun Artikel eingeschlossen werden.
Ergebnisse
Durch eine präoperative neurobiologische (Schmerz‑)Edukation können postoperative Katastrophisierungstendenzen sowie die postoperative Kinesiophobie positiv beeinflusst werden. Keinen Einfluss hat eine präoperative neurobiologische Edukation auf postoperativen Schmerz und Funktion. Inkonsistenz besteht bislang in der Herangehensweise der PNE (Pain Neuroscience Education).
Schlussfolgerung
Eine präoperative Reduktion von Angst und schmerzaufrechterhaltenden Faktoren v. a. auf psychologischer und sozialer Ebene hat einen positiven Effekt auf die postoperative subjektive Schmerzbewertung, was sich in einer Reduktion von Angst, Katastrophisierungstendenzen und einer geringeren Inanspruchnahme von postoperativen Leistungen im Gesundheitswesen widerspiegelt.
A systematic study was performed to understand the effects of the devulcanizing agent dibenzamido diphenyl disulfide (DBD) on the vulcanization and devulcanization process of a sulfur-cured ethylene-propylene-diene monomer (EPDM) rubber. The influence of DBD on vulcanization was investigated by mixing DBD with virgin rubber and curative system. The devulcanization of rubber waste was achieved with varying amounts of DBD ranging from 0.4 to 13.8 wt% and temperatures from 150 to 200°C. The quality of vulcanizates and devulcanizates was evaluated by rheometer tests, temperature scanning stress relaxation measurements, and analysis of mechanical properties. During vulcanization, DBD acts as an accelerator in the presence of sulfur. When accelerators are added, the scorch time increases, and the cure rate decreases. Thus, DBD acts as a retarder. In the presence of activators, DBD leads to a significant reduction of crosslink density. This results in composites with high elongation at break and poor compression set values. The efficiency of the devulcanization of rubber waste depends strongly on DBD concentration and temperature. The monosulfidic crosslinks are cleaved by low concentrations of DBD, while polysulfidic crosslinks require higher concentrations. These results show that DBD is effective as a devulcanizing agent and degrades the network below 200°C.
One challenge of the EU energy transition is the integration of renewable electricity generation in the distribution system. EU energy law proposes a possible solution by introducing “citizen energy communities” (Directive 2019/944/EU) which may be open for “cross-border participation”. This article proposes an innovative way of implementing such cross-border communities by linking distribution systems via a “switchable element”, a generation, storage, or consumption asset with a connection to each country. An optimization model has been developed to calculate the system cost savings of such a connection. Linking regions with complementary characteristics regarding electricity generation and demand via a switchable element leads to more efficient system utilization. Findings are relevant for the transposition of “citizen energy communities” in national laws.
Der vorliegende Beitrag untersucht die Forschungsfrage, inwiefern das coronabedingte Homeoffice Führungshandeln in Kommunikationsagenturen verändert hat und inwiefern diese Veränderungen dem Führungskonzept Digital Leadership entsprechen.
Im coronabedingten Homeoffice hat die Diskussion über „Digital Leadership“ als neues Führungskonzept veränderter Arbeitswelten weiter an Relevanz gewonnen (Amerland, 2021; Bitkom, 2021; Kollmann, 2020). Dennoch zeigt sich im Bereich des Kommunikationsmanagements insbesondere hinsichtlich der Untersuchung von Agenturen eine Forschungslücke zu Digital Leadership während der Coronakrise.
Obwohl Agenturen im Berufsfeld eine große Bedeutung zugeschrieben wird, werden diese in der Forschung wenig betrachtet (Röttger und Zielmann, 2009). Daher untersucht der vorliegende Beitrag die Forschungsfrage, inwiefern das coronabedingte Homeoffice Führungshandeln in Kommunikationsagenturen verändert hat und inwiefern diese Veränderungen dem Führungskonzept Digital Leadership entsprechen. Zur Untersuchung der Forschungsfrage wurden qualitative, leitfadengestützte Experteninterviews (N = 5) mit Führungskräften aus mittelgroßen Agenturen durchgeführt und mithilfe der qualitativen Inhaltsanalyse (Mayring, 2016) ausgewertet. Die Ergebnisse zeigen entgegen der Hypothese, dass das Führungshandeln in den befragten Agenturen bereits vor der Coronakrise dem Führungskonzept „Digital Leadership“ im Sinne des VOPA+-Modells von Petry (2016) entsprach. Einzelne Merkmale des Führungskonzeptes wie Agilität und Vernetzung wurden in weiten Teilen in den befragten Agenturen durch das coronabedingte Homeoffice allerdings katalysiert. Neben einer Verlagerung der Führung in den virtuellen Raum wurden auch Veränderungen im Führungshandeln in Form neuer Maßnahmen wie mehr Fürsorge, Kommunikation und Boundary Management festgestellt. Diese Veränderungen im Führungskonzept Digital Leadership können als Implikationen für Führungskräfte in einem Modellansatz zu „Digital Leadership im Homeoffice“ festgehalten werden. Post-Covid müssen Digital Leader ihr Führungskonzept zudem an die sich weiter verändernden Anforderungen hybrider Arbeitswelten adaptieren. An dieser Stelle wird der Bedarf an weiterführender Forschung zu Führungshandeln in hybriden Arbeitswelten, insbesondere im Bereich des Kommunikationsmanagements, deutlich.
Das Ziel des Artikels besteht darin, mögliche Einsatzfelder von Nudges im Boundary-Management zu erläutern sowie die Eignung von Self-Nudging zur Stärkung der Boundary-Management-Kompetenzen von mobil arbeitenden dual Studierenden zu diskutieren. Im Rahmen einer Masterarbeit wurden zu diesem Zweck im ersten Schritt mögliche Verbindungsoptionen zwischen den beiden Forschungsfeldern aus der Theorie abgeleitet und aufgezeigt, dass diverse Nudges im Boundary-Management denkbar sind. Im zweiten Schritt wurde eine empirische Untersuchung zur Erfassung der Auswirkung von Self-Nudging auf das Boundary-Verhalten von mobil arbeitenden dual Studierenden durchgeführt. Im Zuge einer einwöchigen Feldphase wurde ein Zeitmanagement-Nudge von sechs Versuchsteilnehmenden getestet und anschließend dessen Wirksamkeit mithilfe von qualitativen Leitfadeninterviews erfasst. Die Ergebnisse der qualitativen Inhaltsanalyse zeigen, dass das Self-Nudging zur Förderung des Boundary-Management- Bewusstseins beitrug sowie die Selbstkontrolle und Selbstsorge der dual Studierenden steigerte. Der Nudge regte zur Entwicklung neuer Boundary-Taktiken und eigener Self-Nudging-Konzepte an. Dennoch resultierten keine maßgeblichen Veränderungen im Boundary-Verhalten der dual Studierenden. Zusammenfassend ist das Self-Nudging zur präventiven Förderung des Boundary-Managements beim mobilen Arbeiten geeignet, jedoch nicht zur Behebung von bereits bestehenden Boundary-Konflikten. Zudem konnte aufgezeigt werden, dass bei der Konzeption und Gestaltung von Nudges im Boundary-Management eine Ausrichtung an den Boundary-Typen nicht ausreicht, da alle Teilnehmenden verschiedene Formen des Self-Nudgings favorisierten.
Dieser Aufsatz soll auf Grundlage einer quantitativen Online-Befragung diskutieren, inwiefern digitale Nudges zur Reduzierung der Smartphone-Nutzung als wirksam eingeschätzt werden und welche Mechanismen ihre eingeschätzte Wirkung beeinflussen.
Die COVID-19-Pandemie hat das Online- Verhalten der Deutschen noch einmal deutlich in die Höhe getrieben. Mit der gestiegenen medialen Internetnutzung (um 21 Minuten pro Tag) ist auch das Smartphone zu einem immer wichtigeren Begleiter im Alltag geworden. Doch immer mehr Menschen wollen einen Rückwärtsgang einlegen und bewusst ihr digitales Konsumverhalten einschränken. Da heutzutage vermehrt Entscheidungen auf digitalen Endgeräten getroffen werden, soll dieser Aufsatz auf Grundlage einer quantitativen Online-Befragung diskutieren, inwiefern digitale Nudges zur Reduzierung der Smartphone-Nutzung als wirksam eingeschätzt werden und welche (psychologischen) Mechanismen ihre eingeschätzte Wirkung beeinflussen. Mittels eines standardisierten Fragebogens wurden sowohl verschiedene Verhaltenstendenzen, die Smartphone-Sucht und die Art des Nudges als Einflussfaktoren auf die eingeschätzte Wirksamkeit digitaler Nudges als auch der Einfluss demographischer Merkmale (Geschlecht, Alter) auf die Tendenz zur Smartphone-Sucht analysiert. Die Ergebnisse zeigen, dass die eingeschätzte Wirksamkeit digitaler Nudges von vielen individuellen Faktoren abhängt, zum Beispiel, wie stark Personen zu einem Sucht-ähnlichen Nutzungsverhalten tendieren. Für das Kommunikationsmanagement bedeutet dies, dass zu Beginn der Konzeption und Platzierung von (digitalen) Nudges eine umfassende Zielgruppenanalyse notwendig ist, um zielgerichtet Verhalten zu beeinflussen.
Der Beitrag beschäftigt sich mit der Wirksamkeit von Nudging, Boosting und Empowerment in der Gesundheitsvorsorge. Hierfür wurde die Einstellung von jungen, ernährungsbewussten
Studentinnen gegenüber vorgestellten Nudging-, Boostingund Empowerment-Maßnahmen zur gesünderen Ernährung untersucht.
Der vorliegende Aufsatz beschäftigt sich mit der Wirksamkeit von Nudging, Boosting und Empowerment in der Gesundheitsvorsorge. Hierfür wurde im Rahmen einer Bachelorarbeit eine Gruppendiskussion durchgeführt und die Einstellung von jungen, ernährungsbewussten Studentinnen gegenüber vorgestellten Nudging-, Boosting- und Empowerment-Maßnahmen zur gesünderen Ernährung untersucht. Die Diskussion wurde anhand einer qualitativen Inhaltsanalyse ausgewertet, und darauf aufbauend wurden theoretisch und empirisch fundierte Handlungsempfehlungen entwickelt. Die Ergebnisse der Untersuchung zeigen, dass keine der präsentierten Maßnahmen allein dazu motiviert, sich gesünder zu ernähren. Die Wirksamkeit hängt bei allen Konzepten maßgeblich von der Gestaltung der Maßnahmen, dem eigenen Aufwand und den mitgebrachten Voraussetzungen der Individuen ab. So greift der Nudge nicht mehr bei bereits bewussten Verbraucher*innen, und der Boost verzeichnet bei höherem eigenen Aufwand trotzdem keine deutlich höhere Wirksamkeit. Lediglich der Empowerment-Maßnahme wird eine langfristige Wirksamkeit zugeordnet, allerdings ist sie mit dem höchsten Aufwand verbunden. Auf Basis der Forschungserkenntnisse lässt sich schlussfolgern, dass ein Methoden-Mix aus kurzfristig und langfristig wirksamen kommunikativen Maßnahmen einen Weg darstellt, verschiedene Zielgruppen zu erreichen und zu gesünderer Ernährung zu motivieren.
Mitarbeiterbezogene Erwartungen und Bedürfnisse in der internen Krisenkommunikation in Unternehmen
(2022)
Ziel dieses Beitrags ist es, zum Wissen über interne Krisenkommunikation beizutragen, indem die Erwartungen und Bedürfnisse von Mitarbeitenden im Kontext der Krisenkommunikation untersucht werden. Im ersten Schritt ergab eine Literaturrecherche, dass es in von Krisen betroffenen Organisationen zu einer Fokussierung auf externe Stakeholder kommt. Interne Stakeholder werden in Krisensituationen oft vernachlässigt. Zudem gibt es einen Mangel an empirischer Evidenz über die Erwartungen und Bedürfnisse der Mitarbeitenden. Diese wurden im zweiten Schritt in einer explorativen Onlineumfrage mit 37 Mitarbeitenden verschiedener Organisationen analysiert, um empirisch fundierte Hypothesen zu generieren. Es wurden 14 Hypothesen zu den Erwartungen und Bedürfnissen der Mitarbeitenden in der internen Krisenkommunikation entwickelt. Die Ergebnisse dieser Arbeit geben Anregungen für weitere Forschungen und sind limitiert durch den Umfang der Literaturrecherche und die Teilnehmenden der durchgeführten Befragung.
Obwohl sich die Anforderungen im Sport und dem Musizieren ähneln, ist die Musikerphysiotherapie längst nicht so entwickelt wie die Sportphysiotherapie. Dabei lassen sich die sogenannten „Performance-Related Musculoskeletal Disorders“ erfolgreich mit Manueller Therapie oder Physiotherapie, z. B. mit Hilfe einer Bewegungsanalyse, therapieren. Prof. Dr. med. Christoff Zalpour gibt einen Überblick über das Feld der Musikerphysiotherapie, deren Potenzial noch lange nicht vollends erschlossen ist.
Die Anforderungen an zukünftige Teilnehmende eines Arbeitsmarktes verändern sich. Das von Frithjof Bergmann begründete Prinzip der Neuen Arbeit (Bergmann, 2004) ist aktuell Gegenstand zahlreicher Diskussionen und Debatten über aktuelle und zukünftige Arbeitswelten. Die sich daraus ergebenden Kompetenzanforderungen passen mit der Lehre in Hochschulen wenig zusammen. Zunehmend werden agile Lernszenarien diskutiert.
Das Inverted Classroom Modell (ICM) erfreut sich seit einigen Jahren großer Beliebtheit in der Hochschullehre. Aus Studierendensicht ist die Teilnahme an einer ICM-Veranstaltung aber eine Herausforderung. Für ein erfolgreiches Lernen sind insbesondere personale Kompetenzen wie Selbstmotivation, Durchhaltevermögen und Selbstregulationskompetenz erforderlich (Pöpel & Morisse, 2019). Um diesem Umstand entgegenzuwirken, wurde vom Autor ICM mit Ideen aus Scrum für eine Informatik-Lehrveranstaltung kombiniert (siehe auch (Morisse & Heidemann, 2021)). Die Wirkung von Scrum kann sich nur entfalten, wenn die Arbeit in einzelne Sprints aufgeteilt wird und bei der Bearbeitung der Sprints auch die eigene Zusammenarbeit im Rahmen einer Retrospektive kritisch reflektiert wird. Zu diesem Zweck wird der gesamte Inhalt der Lehrveranstaltung in eine Anzahl von thematischen Blöcken aufgeteilt, die als Lehr- und Lerninhalte für die Lern-Sprints der Scrum-Umsetzung werden. Für jeden Themenblock müssen die theoretischen Inhalte erarbeitet sowie eine eigenständige Zusammenfassung formuliert werden. Ergänzend dazu wurde ein Software-Produkt definiert, in dessen Rahmen die theoretischen Inhalte einfließen konnten.
Die Durchführung eines Reviews und einer Retrospektive schließen bei Scrum einen Sprint ab. Genau dies lässt sich auch im Hochschulkontext sehr gut als Feedback-Instrument durchführen. Das Review bestand in der Inspektion der entwickelten Software. Mit der Retrospektive wird die eigene Zusammenarbeit im Team kritisch reflektiert. Ein besonderes Augenmerk verdient der kommunikative Stil zwischen Lehrenden und Studierenden. Bei einem Veranstaltungskonzept, welches getragen wird von Interaktion und Diskussion, kommt einer empathischen und wertschätzenden Kommunikation eine besondere Bedeutung zu. Das dies in der vorgestellten Veranstaltung scheinbar gelungen ist, zeigt das Zitat eines der teilnehmenden Studierenden „Ich freue mich immer auf die Review-Termine“. Zur Erinnerung: Das Review ist der Termin zur Vorstellung des erreichten Ergebnisses, also eher ein Prüfungs-Setting, bei dem Studierende ihre Arbeit präsentieren. Weitere positive Resonanzmerkmale durch die Studierenden waren die hoffnungsvollen Fragen, ob denn die Veranstaltungen im kommenden Semester auch nach ICMScrum organisiert sind.
The increasing diversity of cultural backgrounds offers potential for a more elaborated information processing, yet has been shown to be challenging for individuals, due to intergroup hostility, prejudices, and difficulties of intercultural communication. Current research thus focusses on the interaction of employees with different cultural heritages, as well as on their intergroup attitudes and competences. Thereby, leaders have been shown to shape the way diversity is considered in their teams in a top-down process. However, their perception of diversity as well as related challenges and chances are poorly investigated. The current paper thus aims to contribute to the understanding of leader’s perspective on and role in diversity-management by building on a comparative qualitative study with sixteen employees and twenty-two leaders. Research questions are how employees and leaders perceive cultural diversity from their specific point of view, which experiences are likely to contribute to their opinion on and perception of diversity and in how far do employees and leaders differ in these aspects. The results show that employees are aware of the topic of diversity in general but have poor competences in dealing with diversity in their daily working life. This seems to be associated with lack of experience with intercultural interaction and a lack of support from the respective organizations/leaders. Leaders are rarely aware of this lack of support. The results indicate that leaders’ experiences with cultural and age diversity, their identification with the company and previous diversity measures in the context of the companies’ policy towards diversity seem to be relevant for the formation of leaders’ attitudes. As a consequence, most participants focus on the question whether they do or do not want diversity within their teams and companies, while they actually fail to perceive the diversity that is already there.
Oleamide is used as a lubricant in the manufacturing and application of polypropylene (PP) medical devices. Samples of PP were prepared with 0, 1500, and 15 000 ppm oleamide content as lubricant. The samples were either left non-sterile, sterilized with ethylene oxide (ETO), γ-radiation (γ) or autoclaved (A) and stored for up to 4 weeks. To determine the oleamide bulk-to-surface distribution depending on sterilization method and storage time an extraction method and a washing technique were applied. The oleamide content was determined by gas chromatography (GC-FID) and compared with the coefficient of friction (COF). The COF dependent on the measured lubricant content at the surface. The content of lubricant on the surface depends on the type of sterilization: ETO increased the lubricant content to some extent, γ-sterilization and autoclaving reduced it. After storage, no migration of the lubricant to the surface could be detected.
Farmland bird populations are in a deep crisis across Europe. Agri-environment schemes (AES) were implemented by the European Union to stop and reverse the general decline of biodiversity in agricultural landscapes. In Germany, flower strips are one of the most common AES. Establishing high-quality perennial wildflower strips (WFS) with species-rich native forb mixtures from regional seed propagation is a recent approach, for which the effectiveness for birds has not yet been sufficiently studied. We surveyed breeding birds and vegetation on 40 arable fields with WFS (20 with single and 20 with aggregated WFS) and 20 arable fields lacking WFS as controls across Saxony-Anhalt (Germany). Additionally, vegetation composition, WFS quantity and landscape structure (e.g. distance to nearest woody element) were considered in our analyses. All WFS were established with species-rich native seed mixtures (30 forbs) in agricultural practice as AES. Arable fields with WFS had a higher species richness and territory density of birds than controls, confirming the effectiveness of this AES. A forb-rich vegetation was the main driver promoting birds. Flower strip quantity at the landscape level had positive effects only on bird densities, but also single WFS achieved benefits. A short distance from WFS to woody elements increased total bird species richness. However, the density of farmland birds, which are target species of these AES, were negatively affected by the proximity and proportion of woody elements in the vicinity. The effect of the proportion of non-intensively used open habitats and overall habitat richness was unexpectedly low in the otherwise intensively farmed landscape. Species-rich perennial WFS significantly promoted breeding birds. Successful establishment of WFS, resulting in high-quality habitats, a high flower strip quantity as well as implementation in open landscapes were shown to maximise the effectiveness for restoring declining and AES target farmland birds.
Adventitious root (AR) formation is the basis of vegetative propagation in rose, be it via stem cuttings or via stenting. During this process, wounding plays a pivotal role since cell reprogramming takes place at the tissue adjacent to the wound. We investigated the effects of wounding on AR formation on leafy single-node stem cuttings of the rose rootstock R. canina ‘Pfänder’ (codes R02-3 and R02-6) and the cut rose cultivar Rosa ‘Tan09283’ (Registration name ‘Beluga’). Laser wounding treatments were based on the assisted removal of tissue layers located in the bark. The positioning of wounding was studied based on two marking directions: along the cutting base (strip pattern) and around the cutting base (ring pattern). Additionally, the effects of external supply of indole-butyric acid (IBA 1 mg L-1) on rootingwere analyzed. Results showedthat inorder toremovespecific tissue layers, the calculation of the laser energy density (J cm-2) in terms of cutting diameter was necessary. Interestingly, the application of energy densities from 2.5 J cm-2 up to approximately 8.5 J cm-2 were sufficient to expose the tissue layers of epidermis up to regions of phloem. Regarding AR formation for R. canina ‘Pfänder’, characterized by a low rooting response, an increase in the rooting percentage was registered when the laser treatment eliminated the tissue up to phloem proximities. Analysis of the nodal position showed that bud location was a preferential place for AR formation independently of wounding treatment. In case of Rosa ‘Tan09283’, laser treatments did not reduce its high rooting capacity, but an apparent reduction in rooting quality due to an investment in tissue healing was observed when wounding reached deeper layers such as parenchyma and sclerenchyma. Results also showeda strongARformation directly fromwounded regions in case of Rosa ‘Tan09283’ specifically when the woundwas located below the axillary bud. In conclusion, wounding by assisted-elimination of layers by laser can induce positive effects on AR formation of single-node stemcuttings of the rose if energy applied is able to expose phloemproximities,a longitudinalorientation, and relative position to the axillary bud are considered.
Background
Spinach is a nitrogen (N) demanding crop with a weekly N uptake of up to 60 kg ha–1. Consequently, a high N supply is required, which can temporarily lead to high quantities of nitrate (NO3–) being at risk of leaching.
Aims
The objective of this study was to develop a N fertilization approach to reduce the risk of NO3– leaching in field-grown spinach production without adversely affecting crop yield and quality at an early and late harvest stage.
Methods
Ten fertilization trials were conducted to compare different base fertilization rates and splits of top dressings. For top dressings, granulated fertilizers or foliar sprays were used. In a further treatment, N supply was reduced by withholding the second top dressing of 50–70 kg ha−1.
Results
Nitrate concentration at risk of leaching was considerably reduced by decreasing the base fertilizer rate as well as by splitting the top dressing. However, at an early harvest stage, total aboveground dry mass was reduced by, on average, 6% by these measures across all seasons. In contrast, at a later harvest stage, spinach was less affected by the fertilizer schedule. Urea foliar sprays proved to be insufficient in promoting plant growth and caused leaf necrosis. A reduced N supply led to impaired plant growth and yellowish leaves in both spring and winter.
Conclusions
Base N fertilization of spinach is only required in spring, but not in other seasons. Despite slight yield reduction, the top dressing should be split to reduce the risk of NO3− leaching after an early harvest.
In open-field vegetable production, high quantities of soil mineral nitrogen (Nmin) and N-rich crop residues often remain in the field at harvest. After the harvest of crops in autumn, this N can lead to considerable nitrate (NO3−) losses during the subsequent winter leaching period. In four field trials, different tillage depths (3–4, 10, 30 cm) and dates (early autumn, late autumn, early spring) were investigated to reduce N losses after growing spinach in the autumn. In a further treatment, the nitrification inhibitor 3,4-Dimethylpyrazole phosphate (DMPP) was directly applied to the crop residues. Potential N losses were calculated by a balance sheet approach based on Nmin concentration (0–90 cm), measured N mineralization and N uptake by catch crops. By postponing the tillage date from early to late autumn or spring, resprouting spinach stubbles acted as a catch crop, reducing N losses by up to 61 kg ha−1. However, if the spinach biomass collapsed, the N losses increased by up to 33 kg ha−1 even without tillage. The application of DMPP as well as the tillage depth were less effective. Overall, postponing tillage to spring seems to be the most promising approach for reducing N losses during the off-season.
Hintergrund: Die Digitalisierung durchdringt mittlerweile alle Bereiche unseres Lebens und zunehmend auch das Handlungsfeld der Pflege. Mithilfe medial gestützter Lehrgestaltung können Lernende auf digitale Herausforderungen ihres Berufsalltags vorbereitet werden. Zudem müssen Pflegende über ein individuell und fallbezogen anwendbares Fachwissen verfügen, welches mittels des Konzeptes der hermeneutischen Fallarbeit vermittelt wird. Virtuelle Simulationen können authentische Fallszenarien darstellen und das konventionelle Konzept der Fallarbeit mit moderner Technik erweitern.
Ziel: Ziel der Recherche ist, national und international verwendete Arten digitaler und virtueller Medien in Verbindung mit der Methode der hermeneutischen Fallarbeit im Kontext der Gesundheitsbildung zu identifizieren und dessen Nutzen zu beschreiben.
Methoden: Es ist eine Literaturrecherche im Design eines systematischen Reviews in den Datenbanken CINAHL, MEDLINE via PubMed, Cochrane und Springer Link durchgeführt und mit dem Schneeballprinzip ergänzt worden.
Ergebnisse: Es wurden elf Publikationen eingeschlossen. Die Ergebnisse zeigen überwiegend positive Auswirkungen, die sich in elf Kategorien unterteilen lassen. Schlussfolgerung: Der Einsatz von virtuellen Patient_innen wird auch in der empirischen und mediendidaktischen
Forschung als ein effektives und effizientes Lernarrangement angesehen. Sowohl im positiven wie auch negativen Sinne, sind die Ergebnisse abhängig von der didaktisch-methodischen Aufarbeitung, dem Design der Lernmodule und der Qualität des Mediums wie auch der Lehre.
Freshwater ecosystems host disproportionately high numbers of species relative to their surface area yet are poorly protected globally. We used data on the distribution of 1631 species of aquatic plant, mollusc, odonate and fish in 18,816 river and lake catchments in Europe to establish spatial conservation priorities based on the occurrence of threatened, rangerestricted and endemic species using the Marxan systematic conservation planning tool. We found that priorities were highest for rivers and ancient lakes in S Europe, large rivers and lakes in E and N Europe, smaller lakes in NW Europe and karst/limestone areas in the Balkans, S France and central Europe. The a priori inclusion of well-protected catchments resulted in geographically more balanced priorities and better coverage of threatened (critically endangered, endangered and vulnerable) species. The a priori exclusion of well-protected catchments showed that priority areas that need further conservation interventions are in S and E Europe. We developed three ways to evaluate the correspondence between conservation priority and current protection by assessing whether a cathment has more (or less) priority given its protection level relative to all other catchments. Each method found that priority relative to protection was high in S and E Europe and generally low in NW Europe. The inclusion of hydrological connectivity had little influence on these patterns but decreased the coverage of threatened species, indicating a trade-off between connectivity and conservation of threatened species. Our results suggest that catchments in S and E Europe need urgent conservation attention (protected areas, restoration, management, species protection) in the face of imminent threats such as river regulation, dam construction, hydropower development and climate change. Our study presents continental-scale conservation priorities for freshwater ecosystems in ecologically meaningful planning units and will thus be important in freshwater biodiversity conservation policy and practice, and water management in Europe.
The energy transition can be mapped on four levels. While industry and the state should act on the national and international level, most of the energy transition is taking place at the regional and municipal levels. Here the small-scale and decentralized nature of the new energy world is reflected, where customized individual solutions are created.
Information systems (IS) play a central role in promoting corporate sustainability and pro-environmental behavior. This study explores the use of mobile apps for fostering sustainability-oriented corporate culture. It accentuates issues relating to sustainability-oriented corporate culture (RQ1), app meta-requirements as a strategic approach to addressing these issues (RQ2), as well as design and implementation principles (RQ3). Referring to the literature on sustainability apps, gamification, and nudging, our qualitative research design combines an analysis of four corporate apps intending to promote sustainable behavior and expert interviews (Grounded Theory). The proposed framework supports the planning, realization, and monitoring of this targeted app use. Single cultural dimensions inform seven issues in culture development. Five meta-requirements address this multi-dimensionality, challenges provided by new digital working environments, and principles of Green IT. Four design principles support, extend, and integrate current knowledge on app features, nudging, and gamification. Five variables determine the app intervention and maturity level. We conclude that this targeted app use should intend to foster the sustainability orientation within all dimensions of corporate culture instead of being limited to promoting sustainable behavior.
Der vorliegende Beitrag fokussiert die Bedeutung Nachhaltigkeitsorientierter Unternehmenskultur für den Einsatz von künstlicher Intelligenz im Marketing. Spezifischer skizzieren wir die Einflussmöglichkeiten auf den Einsatz nachhaltiger künstlicher Intelligenz zur Förderung des Sustainable Development Goals 12 (Nachhaltige/r Produktion & Konsum). In einem diskursiven Ansatz führt dieser Beitrag Erkenntnisse aus der Literatur zur nachhaltigkeitsorientierten Unternehmenskultur, nachhaltigen künstlicher Intelligenz und dem Nachhaltigkeitsmarketing zusammen und bildet diese mithilfe des St. Galler Managementmodells ab.
Das Ziel des Beitrags ist es, die Bedeutung von aktiven Kundinnen und Kunden für ein unterstützendes Marketing Management hin zu einer nachhaltigen Entwicklung am Beispiel der Energiewirtschaft aufzuzeigen. Das Menschenbild des homo sustinens kann von besonderer Relevanz sein, um aktive Kundinnen und Kunden im Marketing Management zu verstehen. Dem homo sustinens zugrundeliegend, der sich am Leitbild der Nachhaltigkeit orientiert, ergeben sich vielfältige Ansatzpunkte für den Austauschprozess mit aktiven Kundinnen und Kunden. Sie können befähigt, instrumentalisiert, unterstützt, erzogen oder optimiert werden.
Die Verschwendung von Lebensmitteln im Haushalt wird durch eine komplexe Reihe von routinemäßigen Verhaltensweisen bestimmt, und eine Unterbrechung dieser Routinen könnte zu einer Verringerung dieser enormen Menge an Lebensmittelabfällen führen. In der vorliegenden Studie wird eine solche Unterbrechung der Haushaltsroutinen untersucht: die Essensbox.
Das Potenzial von Essensboxen zur Verringerung verschiedener Arten von Lebensmittelabfällen in Haushalten wird zum ersten Mal in verschiedenen Ländern untersucht. Nachdem wir einen Rahmen für den Vergleich der Auswirkungen verschiedener Mahlzeitentypen auf die Lebensmittelverschwendung geschaffen haben, untersuchen wir anschließend die Auswirkungen einer abonnementbasierten Lebensmittelversorgung (d. h. Mahlzeitendosen) auf die gesamte Lebensmittelverschwendung sowie auf die verschiedenen Arten der Lebensmittelverschwendung: Zubereitung, Kochen und Tellerabfälle. Unser Datensatz enthält 8747 Beobachtungen von Mahlzeiten aus 955 Haushalten in sechs Ländern. Die Ergebnisse eines Bayes'schen Mehrebenen-Hurdle-Lognormal-Modells mit zufälligem Intercept zeigen, dass Essensboxen im Vergleich zu traditionell gekochten Mahlzeiten insgesamt zu einer Verringerung der gesamten Essensabfälle führen (38 % weniger). Mahlzeitendosen verringern vor allem das Auftreten und die Menge der verschwendeten Pfannen- und Topfgerichte (d. h. Kochabfälle) sowie die Menge der Mahlzeitenzubereitungsabfälle, führen jedoch im Vergleich zu herkömmlichen Mahlzeiten zu einem höheren Aufkommen von Zubereitungs- und Tellerabfällen. Dies zeigt, wie sich die Unterschiede zwischen den einzelnen Mahlzeiten auf die Lebensmittelabfälle in den Haushalten auswirken, ein Aspekt, der bisher in der Forschung wenig Beachtung gefunden hat. Während sich die meisten früheren Untersuchungen auf die gesamte Lebensmittelverschwendung in Haushalten konzentrierten, zeigt unsere Studie, dass die Unterscheidung zwischen verschiedenen Arten von Lebensmittelabfällen in Haushalten wichtige neue Erkenntnisse liefern kann.
Dieser Artikel befasst sich mit dem bundesweiten Niveau der Treibhausgas (THG)-Emissionen und des Ressourcenverbrauchs in der deutschen Gemeinschaftsverpflegung im Segment "Business" und deren Einsparpotenziale durch verschiedene Szenarien der ungestützten und gestützten Rezeptüberarbeitung. Unter "ungestützt" verstehen wir in dieser Arbeit die intuitive Optimierung von Rezepten durch die Mitarbeiter von Betrieben der Gemeinschaftsverpflegung. Die "unterstützten" Ansätze mussten dagegen bestimmte Zielvorgaben erfüllen, zum Beispiel der Deutschen Gesellschaft für Ernährung; engl. Deutschen Gesellschaft für Ernährung oder das nachhaltige Niveau. Konkret Konkret wird getestet, wie sich (A) eine ungestützte Rezeptüberarbeitung, (B) eine Rezeptüberarbeitung auf Basis von Ernährungsempfehlungen und (C) eine Rezeptüberarbeitung mit wissenschaftlicher Begleitung die Umweltauswirkungen eines Gerichtes beeinflussen. Als methodischer Rahmen diente eine Online-Befragung von Unternehmen der Gemeinschaftsverpflegung sowie eine Szenarioanalyse auf Menüebene und auf nationaler Ebene durchgeführt. Die Ergebnisse basieren zum einen auf empirischen Daten und zum anderen auf Hochrechnungen. Die Ergebnisse zeigen, dass die die bundesweite Umsetzung der Rezepturüberarbeitung nach wissenschaftlichen Vorgaben - wie konkrete Zielvorgaben für die THG Emissionen pro Portion - bis zu 44% des Ressourcenverbrauchs in der deutschen Betriebsgastronomie einsparen kann (das entspricht 3,4 Millionen Tonnen Ressourcen pro Jahr) und bis zu 40 % der THG-Emissionen (0,6 Millionen Tonnen THG-Emissionen pro Jahr) einsparen.
Der Schwerpunkt des vorliegenden Papiers liegt auf der Nachfrageseite. In realen Labors verwenden wir einen standardisierten empirischen Ansatz, um verschiedene Nudging-Maßnahmen aus dem Bereich der physischen Umwelt und des Entscheidungsprozesses der Verbraucher zu vergleichen. Wir vergleichen die Auswirkungen ein und derselben Maßnahme in verschiedenen Umgebungen und die Auswirkungen verschiedener, aufeinander folgender Nudging-Maßnahmen in derselben Umgebung. Die Daten wurden in acht Betriebs- und Schulkantinen in Deutschland in zwei Projektdurchläufen (2016/2017; 2019/2020) erhoben. Es wurde ein ähnliches Interventionskonzept angewandt. Die Vergleichbarkeit wurde durch eine harmonisierte Speisekarte gewährleistet. Die erste Iteration des Projekts ergab, dass nur ein Nudge (oberste Menüposition, +22,5 %) zu einem signifikanten Anstieg der Wahl nachhaltiger Lebensmittel führte, während die Ergebnisse der zweiten Iteration zeigten, dass alle Nudge-Interventionen (beste Thekenposition, +11,6 %; oberste Menüposition, +6,9 %; Etikett plus Informationen, +15,9 %) die Wahl der Verbraucher positiv beeinflussten. Mögliche Erklärungen wie die striktere Einhaltung des Versuchsplans in den Cafeterien, aber auch gesellschaftliche Entwicklungen wie das Aufkommen der Fridays for Future-Bewegung werden diskutiert. Da die Ergebnisse je nach Standort und Umfeld variieren, legen unsere Ergebnisse nahe, dass Nudges situativen Bedingungen angepasst werden müssen, um die höchste Wirksamkeit zu erzielen.
A project was initiated to apply dietary CP reduction under commercial conditions. The main objective was to demonstrate and validate that dietary CP can be reduced without compromising broiler performance in a production system which is already rather efficient. In addition, we wanted to demonstrate the potential of dietary CP reduction on reducing N-excretions especially in the context of German revised regulations and monitoring attempts. Finally, as previous research suggested, few further aspects such as impact of dietary CP reduction on litter quality and quantity, footpad health, change of ingredient inclusion levels and related impact on sustainability impact factors were evaluated.
To investigate the influence of two dietary sources of vitamin D on the vitamin D status, bone metabolism, welfare and birth progress of gestating and lactating sows, forty-nine multiparous sows were randomly assigned to one of two diets: “CON” (n = 25; 50 μg vitamin D3/kg feed) and “HYD” (n = 24; 50 μg 25-hydroxycholecalciferol/kg feed). The basal diets were protein- and phosphorus-reduced. The trial started on day 3 ante insemination of the sows and ended with weaning of the piglets on day 28 postpartum. Dietary supplementation of 25-hydroxycholecalciferol resulted in improved maternal vitamin D status (p < 0.001), fewer gait changes (p < 0.01) and longer standing time after feeding (day 5 ante partum; p < 0.05) compared to vitamin D3. However, the bone markers CrossLaps and osteocalcin were not affected. Overall, the present results suggest that sows fed 25-hydroxycholecalciferol instead of vitamin D3 showed improved locomotion and stance strength. However, this outcome is probably not related to altered bone metabolism. The underlying mechanisms must be investigated in further studies.
