Guided by cultural labor economics, the paper analyzes the career paths of former actors from popular television soap operas, and addresses in particular, if and under which conditions such serial engagements may function as a stepping stone for a subsequent professional acting career. A novel database of 396 German artists with detailed and long-term biographical information is used for the quantitative empirical analyses. The results indicate that soaps, contrary to popular opinion, function as a stepping stone, especially for younger actors. However, soap engagements should be rather short but long enough to allow artists to play multiple roles in other shows or films besides being in the cast of a soap. While formal acting education does not influence soap actors’ future filmographies, there is evidence that it helps artists to find jobs in arts-related occupations such as voice acting. Finally, publicity and media presence foster a later acting career. Practical implications for artists and their managers are outlined, along with a discussion on the meaning of serials for the creation and commercialization of stars.
In this essential, Josef Gochermann provides a compendium of the essential elements of technology management and answers ten important questions on how to identify new technologies, properly evaluate relevant technologies, recognize opportunities and risks in time, and position yourself for technological success. He shows how to use technologies beneficially, make relevant technologies available at the right time, recognize the end of a technology's performance in time, and plan the use of technologies strategically and for the future.
Background: While health informatics recommendations on competencies and education serve as highly desirable corridors for designing curricula and courses, they cannot show how the content should be situated in a specific and local context. Therefore, global and local perspectives need to be reconciled in a common framework.
Objectives: The primary aim of this study is therefore to empirically define and validate a framework of globally accepted core competency areas in health informatics and to enrich this framework with exemplar information derived from local educational settings.
Methods: To this end, (i) a survey was deployed and yielded insights from 43 nursing experts from 21 countries worldwide to measure the relevance of the core competency areas, (ii) a workshop at the International Nursing Informatics Conference (NI2016) held in June 2016 to provide information about the validation and clustering of these areas and (iii) exemplar case studies were compiled to match these findings with the practice. The survey was designed based on a comprehensive compilation of competencies from the international literature in medical and health informatics.
Results: The resulting recommendation framework consists of 24 core competency areas in health informatics defined for five major nursing roles. These areas were clustered in the domains “data, information, knowledge”, “information exchange and information sharing”, “ethical and legal issues”, “systems life cycle management”, “management” and “biostatistics and medical technology”, all of which showed high reliability values. The core competency areas were ranked by relevance and validated by a different group of experts. Exemplar case studies from Brazil, Germany, New Zealand, Taiwan/China, United Kingdom (Scotland) and the United States of America expanded on the competencies described in the core competency areas.
Conclusions: This international recommendation framework for competencies in health informatics directed at nurses provides a grid of knowledge for teachers and learner alike that is instantiated with knowledge about informatics competencies, professional roles, priorities and practical, local experience. It also provides a methodology for developing frameworks for other professions/disciplines. Finally, this framework lays the foundation of cross-country learning in health informatics education for nurses and other health professionals.
Technological support options for the usage of Brazilian Açaí berries in the European Food Market
(2022)
The highly perishable fruit açaí grows on palm trees in northern Brazil and is colloquially known as a berry with high nutritional value. The seed of the drupe makes up around 85 percent of the fruits weight and only the pulp around the seed is used for human consumption. The manufacturing step after harvest includes the pulping and the preservation of the fruit. The preservation step is necessary, because the açaí pulp contains a high microbial load. There are several preservation processes including the use of chlorinated or ozonated water, alcoholic fermentation, pasteurization, freezing or dehydration. Those techniques are overall not very gentle and have the potential to leave residues in the final product, which can change its typical sensorial characteristics. Therefore, an experiment was conducted, to see if a relatively new gentle preservation method called PEF can reduce the microbial load in an açaí- smoothie.
For this purpose, a PEF-machine was built and verified based on the paper from HEINZ ET AL. [2003]. The self-built machine works efficiently, when there is a reduction of microorganisms like Escherichia coli in apple juice due to the induced Pulsed Electric Fields. If this is the case, the described experiment with açaí-smoothie can be carried out with the self-built PEF- machine. In this experiment the results of the validation of this PEF-machine were not comparable to those from the paper from HEINZ ET AL. [2003]. So, the self-built PEF-machine in Brazil did not work sufficiently. Hence, the experiment which should show that a reduction of microorganisms, such as Escherichia coli, in açaí-smoothie with PEF is possible, was performed in Germany. It was accrued out at ELEA with using the PEFPilotTM Dual. This experiment confirmed the assumption, that microorganisms can be reduced in açaí-smoothie with PEF. Escherichia coli was reduced by 2 logs, Saccharomyces cerevisiae by 3 logs and Lactobacillus plantarum by 6 logs. And a comparison between PEF and the known preservation methods for açaí showed that it can be a compatible alternative.
Moreover, the topic, how açaí fits into the European Food Market is answered within this paper. When offering açaí food products to the European population, ideas can be originated from the well-working Brazilian market. It can be helpful to mix açaí with known European fruits for a better acceptance by the people. Then açaí can help to meet the Europeans needs of the current time for fresh and healthy food, especially when preserved with PEF. Furthermore, it is important to work towards a sustainable supply chain system from the cultivation until the unloading at the destination in Europe. Sustainability is important for the integration in the European market, not only for environmental protection, but also in terms of social stability and marketing purposes. In addition, access requirements, further food-related regulations, and the seasonality of açaí present a major hurdle.
Building on this thesis, further papers shall be written, not only in the field of the preservation of the açaí pulp with PEF, but also in the direction of combined preservation methods for açaí, the sustainable usage of the açaí seeds, product innovations containing the Brazilian fruit or various market research.
By drawing on the two prevailing economic stardom theories, the paper investigates the sources of superstardom in the US movie industry. For the econometric analysis, we use income and popularity data of screen actresses and actors from the annual Celebrity 100 lists as published by Forbes Magazine. The empirical findings indicate that Hollywood, in contrast to other professional settings, supports two different types of stars. While 'talent stars' exploit acting merit, it is media exposure that drives the income of 'publicity stars'. Apparently, in the motion picture industry both underlying resources are equally important and equally valued. Based on these insights we develop concrete recommendations for the career management of artists and the management of film projects.
The increasing complexity of caseloads in SLT practice, e.g. due to higher comorbidity, lacking information or experience in the
treatment of complicated cases, calls for support from experienced as well as specialist practitioners from within the field - especially
for novice therapists. One way to tackle these challenges may be peer coaching and how it can be employed within the educational
and professional SLT setting.
Peer coaching was implemented across five semesters of a successive SLT study programme at a University of Applied Sciences in
Germany. The approach was embedded in a clinical reasoning seminar with 25 SLT students who each presented a challenging case
study from their current workload. All participants completed a short online survey to evaluate the feasibility of the team approach
within this setting as well as their personal benefit and development re. the discussed case studies.
Students felt encouraged by being able to share their experience and tackle actual challenges. They particularly valued receiving
answers from a broad range of other SLTs but also contributing to other students’ queries and providing practical solutions for
them. All participants felt that peer coaching was an appropriate approach for clinical reasoning to support their professional as well
as personal development. Other outcomes were a perceived increased ability to employ metacognitive reflection to be used with
their whole caseload but also a prospective need for further training. Some students suggested the employment of peer coaching
within their work setting.
In the educational as well as professional SLT setting, peer coaching can be successfully employed, triggering metacognitive
reflection re. practitioner’s thinking and acting, resulting in an increased awareness of needs and skills as part of the clinical
reasoning process.
Artificial intelligence (AI) promises transformative impacts on society, industry, and agriculture, while being heavily reliant on diverse, quality data. The resource-intensive "data
problem" has initialized a shift to synthetic data. One downside of synthetic data is known as the "reality gap", a lack of realism. Hybrid data, combining synthetic and real data, addresses this. The paper examines terminological inconsistencies and proposes a unified taxonomy for real, synthetic, augmented, and hybrid data. It aims to enhance AI training datasets in smart agriculture, addressing the challenges in the agricultural data landscape. Utilizing hybrid data in AI models offers improved prediction performance and adaptability.
The 3GPP release 16 integrates TSN functionality into 5G and standardizes various options for TSN time synchronization over 5G such as transparent mode and bridge mode. The time domains for the TSN network and the 5G network are kept separate with an option to synchronize either of the networks to the other. The TSN time synchronization over 5G is possible either by using the IEEE 1588 generalized Precision Time Protocol (gPTP) based on UDP/IP multicast or via IEEE 802.1AS based on Ethernet PDUs. The INET and Simu5G simulation frameworks, which are both based on the OMNeT++ discrete event simulator, are widely used for simulating TSN and 5G networks. The INET framework comprises the 802.1AS based time synchronization mechanism, and Simu5G provides the 5G user plane carrying IP PDUs. We modified the 802.1AS-based synchronization model of INET so that it works over UDP/IP. With that, it is possible to synchronize TSN slaves (connected to 5G UEs), across a 5G network, with a TSN master clock, present within a TSN network, that is connected to the 5G core network. Our simulation results show that 500 microseconds of synchronization accuracy can be achieved with the corrected asymmetric propagation delay of uplink and downlink between the gNodeB (gNB) and the User Equipment (UE). Furthermore, the synchronization accuracy can be improved if the delay difference between uplink and downlink is known.
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.

Sustainable Digital Entrepreneurship : Examining IT4Sustainability as Business Development Path
(2022)
There is an increasing interest within the field of Information Systems as well as political agendas to identify the potential of digital technologies to promote sustainable development. Nonetheless, sustainable entrepreneurship and digital entrepreneurship are widely treated separately within the literature, suggesting that there is little understanding of how entrepreneurs could employ digital technologies to promote sustainable development. Based on an empirical, qualitative research approach, relying on Grounded Theory methodology, this paper identifies characteristics of sustainable digital entrepreneurs. An investigation of the manifestations of the sustainable digital orientation reveals a rather diffuse understanding of the relation and potential synergy effects. In response to this gap, the paper presents examples on how sustainable digital entrepreneurs employ digital and disruptive technologies to tackle sustainability challenges (IT4Sustainability development path), including information and communication technology, such as digital platforms, artificial intelligence, or drone technology. The presented approaches range from second-mover approaches associated with low digital maturity limited to the business level to the development of new business models facilitating the sustainable transition of whole sectors. These insights are summarized in an IT4Sustainability maturity model, which presents different starting points for entrepreneurs. Relevant theoretical, practical, and policy implications are discussed, especially concerning the education on IT4Sustainability, including Corporate Digital Responsibility.
In recent years, various studies have highlighted the opportunities of artificial intelligence (AI) for our society. For example, AI solutions can help reduce pollution, waste, or carbon footprints. On the other hand, there are also risks associated with the use of AI, such as increasing inequality in society or high resource consumption for computing power. This paper explores the question how corporate culture influences the use of artificial intelligence in terms of sustainable development. This type of use includes a normative element and is referred to in the paper as sustainable artificial intelligence (SAI). Based on a bibliometric literature analysis, we identify features of a sustainability-oriented corporate culture. We offer six propositions examining the influence of specific manifestations on the handling of AI in the sense of SAI. Thus, if companies want to ensure that SAI is realized, corporate culture appears as an important indicator and influencing factor at the same time.
Die Ernährung ist für etwa 30 % des weltweiten Verbrauchs an natürlichen Ressourcen verantwortlich. Um die negativen Auswirkungen des Ernährungssektors auf die Umwelt und die Gesellschaft zu begrenzen, ist der Verbrauch und die Verarbeitung von Lebensmitteln mit vermeintlich geringen negativen Auswirkungen ein wichtiges Thema bei den Bemühungen um eine nachhaltige Entwicklung. In den Großküchen sind klar definierte Indikatoren zur Bewertung der Auswirkungen von Geschäftsaktivitäten erforderlich, um dieses Ziel zu erreichen. Die Forschungs- und Entwicklungsarbeiten im Rahmen des NAHGAST-Projekts liefern Grundlagen, die bei diesen Bemühungen eine wichtige Hilfe sein können. Es wurden zwei Versionen eines Bewertungsinstruments mit Indikatoren unterschiedlicher Komplexität (NAHGAST Meal-Basic und NAHGAST Meal-Pro) entwickelt, die von Küchenfachleuten verwendet werden können, um die Nachhaltigkeitsleistung ihrer Produkte - der angebotenen Mahlzeit - zu bestimmen. Eine sachkundige Auswahl von Indikatoren und eine Diskussion darüber, auf welche Prozesse und Auswirkungen sich dieser Indikator im weiteren Kontext bezieht, sind von wesentlicher Bedeutung und werden in diesem Papier erörtert. Darüber hinaus wurden bei der Auswahl der Indikatoren für den Zweck unserer Forschung bestimmte Kriterien gleichzeitig berücksichtigt: (1) Kommunizierbarkeit - Welche Informationen ein Indikator vermitteln kann und wie verständlich diese Informationen für verschiedene Akteure sind; (2) Machbarkeit und Datenverfügbarkeit: Gibt es genügend Daten für einen Indikator und ist es für die Unternehmen realistisch, diesen Indikator in ihre tägliche Arbeitspraxis zu integrieren? (3) Wissenschaftliche Relevanz: Ist der Indikator für die Nachhaltigkeitsbemühungen in größerem Maßstab und für entsprechende Diskussionen in der wissenschaftlichen Gemeinschaft relevant? Die Erkenntnisse aus diesen Überlegungen sind wertvoll für zukünftige Entwicklungen in der Nachhaltigkeitsbewertung in der Außer-Haus-Gastronomie. Das Instrument wurde zur Bewertung einer Reihe von Gerichten verwendet und die Ergebnisse werden als aussagekräftig erachtet. Allerdings dürfen Bewertungen jedoch nicht als genaue Messung, sondern nur als Annäherung an die Nachhaltigkeit von Speisen verstanden werden. Auf der Ebene der einzelnen Indikatoren ermöglichen sie eine detaillierte Analyse und gezielte Optimierung von Rezepten, während die aggregierten Ergebnisse in Form von Etiketten gut an die Kunden kommuniziert werden können. Defizite und Herausforderungen, wie sie in der Anwendungsphase des Projekts festgestellt wurden, zeigen jedoch Forschungslücken im weiteren Kontext auf. Abschließend werden weitere Schritte für eine Integration des Tools in Unternehmensprozesse und verbleibende Anpassungsmöglichkeiten für Unternehmen diskutiert.
The study aimed for the analysis of the impact of pulsed electric field (PEF) pre-treatment on convection (CD) and microwave (MW-CD) assisted air drying. Drying kinetics acceleration and retention of bioactive compounds of PEF pre-treated carrots and apples has been demonstrated. Moreover, the direct and indirect environmental energy impacts of CD and MW-CD technologies with consideration of bioactive compounds preservation has been evaluated. PEF assisted CD and MW-CD demonstrated lower energy use, especially for indirect energy consumption, in the case of carotenoids preservation in dried carrots.
German farmers are required by law to regularly self-assess the welfare of their animals. The project Q Check is aiming at developing a system that will assist farmers to objectively assess animal health and welfare in dairy cows. For this reason, a quarterly report will be compiled from animal-based key indicators to give an overview of the on-farm situation. The anonymised and aggregated reports can also be used for national animal welfare monitoring: Continuous collection of these key indicators enables the summary and publication of figures reflecting the current animal health and welfare status and progressions at federal state and at national level. Q Check is based on four data recording and analysis systems, which are already established in Germany and implemented on a national level. Out of these systems, the most suitable indicators to describe herd health have been selected by 215 experts within a twostage Delphi study. In addition, over 50 face-to-face interviews with stakeholders related to the German dairy sector have been performed in order to take into account the socio-scientific point of view. To complete the process, the selected indicators are currently being checked against mass data and hence tested for suitability regarding monitoring purposes. An automatic farm-specific evaluation of animal health, based on verified indicators, will provide support to farmers in fulfilling their legal requirements and in identifying weak points on the individual farms. A benchmarking system will be set up which will allow tracking the individual herd health indicators in the same farm in their course over time and compared with similar farms. These routinely provided horizontal and vertical statistics will facilitate targeted intervention and support objectified management decisions, implying that dairy farmers can benefit in several respects. In the course of the project, new tools for determining the risk of ketosis in the scope of milk recording will also be validated and implemented at national level to enhance monitoring of this major disease complex. The results of these nationwide, systematic investigations will contribute substantially to objectifying the discussion about the health and welfare situation of dairy cows.
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.
In einer konsumorientierten Kultur ein Leben der Suffizienz zu führen, ist vielleicht eines der ehrgeizigsten Experimente, die ein Mensch unternehmen kann. Um diese Herausforderung zu untersuchen, haben wir einen sozial-praktischen Ansatz gewählt. Dieser Artikel basiert auf 42 qualitativen Interviews, in denen die Befragten gefragt wurden, warum und wie sie sich in einer westlichen Infrastruktur und Kultur suffizient verhalten. Die Ergebnisse deuten darauf hin, dass Suffizienz-orientierte Menschen bei ihren ressourcenintensiven Handlungen auf bestimmte Bedeutungen in der Alltagspraxis zurückgreifen. Diese Bedeutungen umfassen eine Mischung aus umweltfreundlichen Einstellungen, positiven sozialen Absichten und/oder persönlichen Verpflichtungen zur Sparsamkeit. Darüber hinaus haben wir eine Reihe spezifischer Praktiken identifiziert, darunter Teilen, Recycling und Wiederverwendung, die für einen ressourcenschonenden Lebensstil nützlich sind. Für unsere Befragten sind viele dieser Suffizienz-Praktiken regelmäßig im täglichen Leben anzutreffen und wurden nur selten hinterfragt. Anhand einer zusätzlichen Umfrage zeigen wir, dass diese Routinen zu einem weniger ressourcenintensiven Lebensstil führen und wie es einer kleinen Gruppe von Menschen gelungen ist, sich Suffizienzpraktiken anzugewöhnen. Die Mehrheit sieht jedoch keine Notwendigkeit für eine häufigere Umsetzung solcher Routinen, da die täglichen Entscheidungsprozesse weitgehend auf den Konsum von Produkten ausgerichtet sind.
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.
Background
Citizen energy cooperatives (CECOs) are an important element for realising the transformation of the European energy system from a central system, dominated by a few market players to a decentralized system with the participation of many citizens, in which energy supply is largely based on renewable energy sources. This article identifies success factors that ensure a working organization that is capable of implementing projects to support the energy transition and improving the well-being of citizens.
Methods
The aim of this study is to identify success factors using the example of CECOs in north western Germany through a two-step process. The first step is a literature review to identify success factors of CECOs. Second, 12 semi-structured expert interviews with managers of CECOs are conducted and evaluated by means of a qualitative content analysis. The interviews identified the success factors and barriers of CECOs. The interviews were recorded and transcribed verbatim. The coding process was carried out using a qualitative data analysis software (ATLAS.ti 8.4.5,).
Results
The results show that three factors particular should be present, but can influence each other, to lead to successful CECOs: (1) the CECOs require business models with low complexity, as business models that span different stages of the value chain can overwhelm organizational managers. (2) Committed key individuals must be found and promoted. They need the support of the members. (3) Social and ecological principles are the core values of CECOs. The maintenance and strengthening of social–ecological credibility must be promoted in the public perception.
Conclusions
The results show that CECOs emerge from a strong social cohesion in a society. In addition, local "key individuals" need to be identified and supported. To this end, the framework conditions (e.g., policy, legislation, municipal support, etc.) must be adapted in such a way that these "key individuals" in CECOs are not overburdened. The analysis of the interviews also revealed that political or regulatory barriers are often cited as obstacles to the implementation of community energy projects.
This study identifies and evaluates factors for success in innovation work in the Bavarian dairy farming industry. The research is based on an analysis of innovation system theories and a comparison with innovation work in the Dutch dairy sector. Dutch dairy farming is characterized by high productivity and technical efficiency at the farm level. Moreover, important developments in dairy farming have originated in the Netherlands. Therefore, this study delves into the systemic background of the successful innovation work in the Netherlands and makes a comparison with Bavaria. The main result of this study is that innovation work in the Bavarian dairy farming sector is lacking in two respects: end-user (farmer) integration and within-sector cooperation.
Container-based lightweight buildings offer a high ecologic and economic potential when they are designed as nearly zero-energy container buildings (NZECBs). Thus, they are relevant to energy transition in achieving an almost climate-neutral building stock. This paper describes and applies design strategies for suitable building concepts and energy systems to be used in NZECBs for different climates. Therefore, different applications in representative climatic zones were selected. Initially, the global climate zones were characterized and analyzed with regard to their potential for self-sufficiency and renewable energies in buildings. The design strategies were further developed and demonstrated for three cases: a single-family house in Sweden, a multi-family house in Germany, and a small school building in rural Ethiopia. For each case, design guidelines were derived and building concepts were developed. On the basis of these input data, various energy concepts were developed in which solar and wind energy, as well as biomass, were integrated as renewable energy sources. All the concepts were simulated and analyzed with the Polysun® software. The various approaches were compared and evaluated, particularly with regard to energy self-sufficiency. Self-sufficiency rates up to 80% were achieved. Finally, the influence of different climate zones on the energy efficiency of the single-family house was studied as well as the influence of the size of battery storage and insulation.
Nitrogen (N) pollution of groundwater bodies is often a result of high livestock densities combined with use of mineral N fertilisers in Northwest Germany, specifically in combination with sandy soils and high amounts of precipitation. Organic agriculture is discussed as an alternative management practice reducing nitrogen losses due to area-based livestock densities and waiving of mineral N fertilisers. A field trial with integrated ceramic suction cups over three years showed potential for reduced N loads under conventional management specifically with organic fertilisation. Now, the field trial is under transition into organic farming with promising additional benefits for drinking water quality and the great potential to develop optimised N management strategies.
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.
Still Searching or Have You Found It Already? – Usability and Web Design of an Educational Website
(2018)
Background: Apart from a straight-forward and intuitive operability an appealing design determines the success of a website equally well. For this reason, the selection of images and navigation bars plays a determining role. The eye tracking method proved to be appropriate in order to verify the usability of websites. Objectives: The aim of the study was to improve the usability of the website of an educational institute for trainees as target group. Methods/Approach: For this purpose, the use of an eye-tracking technology was combined with a survey. The eye-tracking study was implemented task-oriented. Test persons were asked to search for particular courses within this institute. Results: This approach in combination with a subsequent questionnaire resulted in tangible indications of search patterns of the test group. Furthermore, their perception and their appraisal of the usability as well as the web design was analysed. Even though most tasks were accomplished effectively and efficiently with a positive user feedback, a potential for improvement was detected, in particular with regard to the images and the location of the search field. Conclusions: The selected choice of methods enables researchers and web designers to derive recommendations for the orientation, structure, optimisation and comprehensibility of a website.
background: Musculoskeletal problems (MP) are widespread in performing artists and are due to the special demands of instrument playing, singing or dancing. Additionally, various other factors might contribute to performance-related MP. To provide a specific physiotherapeutic management for performing artists it is important to gain information about the performing art, the individual demands and contributing factors. The subjective examination (SE) is the basis of the clinical reasoning process and the hypothesis forming for further clinical examination and biomechanical analysis. In the present protocol, the SE consists of a questionnaire-based section and an interview-based section and is part of the evaluation process of the neuromusculoskeletal examination of a performing artist specific reference laboratory.
purpose: To develop a standardized SE protocol divided into a questionnaire-based section (Part 1) via web application and an interview-based SE (Part 2) to address MP of performing artists.
methods: The questionnaires for part 1 were selected based on the expertise of the research group and the psychometric properties of each possible questionnaire. A common physiotherapeutic recording of findings which addresses the relevant questions of the SE of MP was used. To adapt the anamnesis to performing-associated MP questions specific to instrument playing, singing and dancing were selected on the basis of a literature search and the expertise of the research group.
summary of content/results: Part 1 consists of three topics. (1) information about the performing art, professional level and sociodemographic data, (2) information about pain and pain processing, and (3) the anatomical location of the main MP including a body region-specific questionnaire. Part 2 is based on the five aspects of clinical practice described by Maitland and the Musculoskeletal Clinical Translation Framework by Mitchell et al. The performing arts specific part is particularly focused on performing art specific considerations, physical and psychosocial contributing factors and art-specific activities.
significance: This standardized SE protocol should help clinicians evaluating the musculoskeletal health of performing artists in a standardized and specific way.
rationale: Musculoskeletal problems are widespread in performing artists and are due to the special demands of instrument playing, singing or dancing. Additionally, various other factors might contribute to performance-related musculoskeletal problems. In order to provide a specific physiotherapeutic management for performing artists, it is important to gain information about the performing art, the individual (biomechanical) demands and contributing factors. The subjective examination is the basis of the clinical reasoning process and the hypothesis forming, which is important for goal setting in further clinical examination and biomechanical analysis. In the present protocol, the subjective examination consists of a questionnaire based section and an interview based section and is part of the evaluation process of the neuromusculoskeletal examination of a performing artist specific reference laboratory.
purpose: The aim of this study was to develop a standardized protocol for an interview based subjective examination of performing artists with musculoskeletal problems. The results of this section of the subjective examination will be combined with the results of the questionnaire based subjective examination , in order to gather as much relevant information as possible to specifically address the individual’s musculoskeletal health status.
methods: A common physiotherapeutic recording of findings which addresses the relevant questions of the subjective examination of musculoskeletal problems was used. In order to adapt the anamnesis to performing-related musculoskeletal problems, questions specific to instrument playing, singing and dancing were selected on the basis of a literature search and the expertise of the research group.
results: The protocol is based on the five aspects of clinical practice described by Maitland and the Musculoskeletal Clinical Translation Framework by Mitchell et al. (2017) .The performing art specific questions especially address (1) performing art specific considerations including style, genre, education and professional level, practice habits, repertoire, and external factors, e.g. concert conditions, (2) performing art specific physical and psychosocial contributing factors, and (3) performing art specific activities which trigger the musculoskeletal problems and help to form hypotheses for the following clinical examination. Individual tracks lead through the subjective examination so that irrelevant questions are skipped depending on the kind of musculoskeletal problem and the performing art practiced by the individual client.
conclusions: A pretest of this standardized anamnesis protocol is ongoing in a special physiotherapy clinic for performing artists since spring 2022. In an iterative approach, the protocol will be continuously improved based on patient feedback and clinical considerations.
Background: Musculoskeletal problems (MP) are widespread in performing artists and are due to the special demands of instrument playing, singing or dancing. In order to specifically evaluate these problems, a reference laboratory is under development. The evaluation covers 4 steps: a subjective examination (SE) including (1) a questionnaire-based online survey and (2) an interview-based anamnesis. On the basis of the results of the SE, hypotheses are formed for (3) an individual musculoskeletal clinical examination and a (4) biomechanical analysis. Here, the focus is on the clinical examination.
Purpose: to develop a standardized protocol for a clinical examination addressing especially musculoskeletal problems in performing artists.
Methods: A common physiotherapeutic clinical examination should be supplemented with techniques, which are specific to performance-related musculoskeletal problems and/or their risk factors. The development was based on a literature search and the clinical expertise of the physiotherapeutic research group.
Summary of content/Results: The performing arts specific clinical examination includes the common analysis of posture as well as passive/active movement capacities and specific differentiating tests in relation to the signs and symptoms of the individual artist. The examination is supplemented by a functional demonstration focusing on the special demands of playing the respective instrument, while singing or dancing. Common overuse risk factors like hypermobility, special anthropometric data or an examination of the motor control of different body regions are addressed. Optional, the various parts of the examination process could be skipped, if not relevant for the individual artist.
Significance: This clinical examination protocol should help clinicians evaluating the musculoskeletal health of performing artists in a standardized and specific way.
Stakeholder relations and sustainability practices of US small and medium-sized manufacturers
(2012)
Purpose: The purpose of this paper is to investigate the adoption of sustainability practices by small and medium-sized manufacturing (SMM) firms, the ways these firms work with their stakeholders for social and environmental purposes, and the relationships between the adoption of sustainability practices, stakeholder interaction, and product and process innovation.
Design/methodology/approach: This paper uses data from telephone interviews with 296 companies, a sustainability typology, and descriptive and statistical regression analysis.
Findings: The majority of the firms are adopting sustainability practices at least to some degree,stakeholders such as community advocacy groups, employees, suppliers, customers, and the localmedia are influencing the adoption of sustainability practices, and firms with high adoption rates of environmental practices are more successful in product and process innovation.Practical implications– The results of this research can help firms and stakeholder groups with their joint efforts to develop sustainability strategies. Community advocacy groups, employees,suppliers, customers, and the local media are capable of motivating firms to give something back tothe communities in which they conduct their business.
Originality/value: This paper contributes new understanding of the adoption of sustainabilitypractices by SMM firms, the ways these firms work with their stakeholders for social and environmental purposes, and the relationships between the adoption of sustainability practices,stakeholder interaction, and product and process innovation.
Stainless steel made to rust: a robust water-splitting catalyst with benchmark characteristics
(2015)
The oxygen evolution reaction (OER) is known as the efficiency-limiting step for the electrochemical cleavage of water mainly due to the large overpotentials commonly used materials on the anode side cause. Since Ni–Fe oxides reduce overpotentials occurring in the OER dramatically they are regarded as anode materials of choice for the electrocatalytically driven water-splitting reaction. We herewith show that a straightforward surface modification carried out with AISI 304, a general purpose austenitic stainless steel, very likely, based upon a dissolution mechanism, to result in the formation of an ultra-thin layer consisting of Ni, Fe oxide with a purity >99%. The Ni enriched thin layer firmly attached to the steel substrate is responsible for the unusual highly efficient anodic conversion of water into oxygen as demonstrated by the low overpotential of 212 mV at 12 mA cm−2 current density in 1 M KOH, 269.2 mV at 10 mA cm−2 current density in 0.1 M KOH respectively. The Ni, Fe-oxide layer formed on the steel creates a stable outer sphere, and the surface oxidized steel samples proved to be inert against longer operating times (>150 ks) in alkaline medium. In addition Faradaic efficiency measurements performed through chronopotentiometry revealed a charge to oxygen conversion close to 100%, thus underpinning the conclusion that no “inner oxidation” based on further oxidation of the metal matrix below the oxide layer occurs. These key figures achieved with an almost unrivalled-inexpensive and unrivalled-accessible material, are among the best ever presented activity characteristics for the anodic water-splitting reaction at pH 13.
During recent decades, many studies have shown that the successful restoration of species-rich grasslands is often seed-limited because of depleted seed banks and limited seed dispersal in modern fragmented landscapes. In Europe, commercial seed mixtures, which are widely used for restoration measures, mostly consist of species and varieties of non-local provenance. The regional biodiversity of a given landscape, however, can be preserved only when seeds or plants of local provenance are used in restoration projects. Furthermore, the transfer of suitable target species of local provenance can strongly enhance restoration success.
We review and evaluate the success of currently used near-natural methods for the introduction of target plant species (e.g. seeding of site-specific seed mixtures, transfer of fresh seed-containing hay, vacuum harvesting, transfer of turves or seed-containing soil) on restoration sites, ranging from dry and mesic meadows to floodplain grasslands and fens. Own data combined with literature findings show species establishment rates during the initial phase as well as the persistence of target species during long-term vegetation development on restoration sites.
In conclusion, our review indicates that seed limitation can be overcome successfully by most of the reviewed measures for species introduction. The establishment of species-rich grasslands is most successful when seeds, seed-containing plant material or soil are spread on bare soil of ex-arable fields after tilling or topsoil removal, or on raw soils, e.g. in mined areas. In species-poor grasslands without soil disturbance and on older ex-arable fields with dense weed vegetation, final transfer rates were the lowest. For future restoration projects, suitable measures have to be chosen carefully from case to case as they differ considerably in costs and logistic effort. Long-term prospects for restored grassland are especially good when management can be incorporated in agricultural systems.
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 biennial plant Gentianella bohemica is a subendemic of the Bohemian Massif, where it occurs in seminatural grasslands. It has become rare in recent decades as a result of profound changes in land use. Using amplified fragment length polymorphisms (AFLP) fingerprint data, we investigated the genetic structure within and among populations of G. bohemica in Bavaria, the Czech Republic, and the Austrian border region. The aim of our study was (1) to analyze the genetic structure among populations and to discuss these findings in the context of present and historical patterns of connectivity and isolation of populations, (2) to analyze genetic structure among consecutive generations (cohorts of two consecutive years), and (3) to investigate relationships between intrapopulational diversity and effective population size (Ne) as well as plant traits. (1) The German populations were strongly isolated from each other (pairwise FST= 0.29–0.60) and from all other populations (FST= 0.24–0.49). We found a pattern of near panmixis among the latter (FST= 0.15–0.35) with geographical distance explaining only 8% of the genetic variance. These results were congruent with a principal coordinate analysis (PCoA) and analysis using STRUCTURE to identify genetically coherent groups. These findings are in line with the strong physical barrier and historical constraints, resulting in separation of the German populations from the others. (2) We found pronounced genetic differences between consecutive cohorts of the German populations (pairwise FST= 0.23 and 0.31), which can be explained by local population history (land use, disturbance). (3) Genetic diversity within populations (Shannon index, HSh) was significantly correlated with Ne (RS= 0.733) and reflected a loss of diversity due to several demographic bottlenecks. Overall, we found that the genetic structure in G. bohemica is strongly influenced by historical periods of high connectivity and isolation as well as by marked demographic fluctuations in declining populations.
There is clinical evidence that cervical lateral glide (CLG) improves neurodynamics and alleviates pain in patients who suffer from neurogenic arm pain. Cervical lateral flexion (CLF) is also a treatment method and a means of testing neurodynamics. However, for both techniques nerve movement has not yet been investigated using ultrasound imaging (US). The purpose of this study was to quantify median nerve movement in the arm during CLG and CLF. For this study 27 healthy participants were recruited. Longitudinal movement of the median nerve was measured using US during CLG and CLF with the shoulder in 30° abduction in the middle and distal forearm (Fad). Data could be obtained from 11 participants (6 women and 5 men, average age 25.6 years, ±2.25) at the middle forearm (Fam) and from 9 participants (5 women and 4 men, average age 27.2 years, ±2.75) at the Fad. When applying CLF, the median nerve moved 2.3 mm (SEM ± 0.1 mm) at the Fam. At the same measuring point the median nerve moved 3.3 mm (SEM ± 0.3 mm, p = 0.005) by applying CLG. At the Fad the difference between CLF and CLF amounted to 0.6 mm (CLF: 1.9 mm (SEM ± 0.2 mm, CLG: 2.5 mm (SEM ± 0.2 mm, p ≤ 0.05). The movements during CLG are larger than during CLF. This difference is statistically significant. However, the statistical relevance cannot be extrapolated to a clinical relevance.
Despite normal neurological bedside and electrodiagnostic, some patients with non-specific neck arm pain (NSNAP) have heightened nerve mechanosensitivity upon neurodynamic testing [1, 2]. It remains however unclear whether this is associated with a minor nerve injury. The aim of this study was to evaluate potential differences in somatosensory function among patients with unilateral NSNAP with and without positive neurodynamic tests and healthy controls.
Quantitative sensory testing was performed in 40 patients with unilateral NSNAP; 23 with positive upper limb neurodynamic tests (ULNTPOS) and 17 with negative neurodynamic tests (ULNTNEG). The protocol comprised thermal and mechanical detection and pain thresholds as well as mechanical pain sensitivity, wind-up ratio and dynamic mechanical allodynia. All parameters were measured in the maximal pain area on the affected side as well as over the corresponding area on the unaffected side. Symptom severity, functional deficits, psychological parameters, quality of life and sleep disturbance were also recorded.
Fifty-seven percent of patients with NSNAP had positive neurodynamic tests despite normal bedside neurological integrity tests and nerve conduction parameters. Clinical profiles did not differ between patient groups. Somatosensory profiling revealed a more pronounced loss of function phenotype in ULNTPOS patients compared to healthy controls. Hyperalgesia (cold, heat and pressure pain) was present bilaterally in both NSNAP group. The ULNTNEG subgroup represented an intermediate phenotype between ULNTPOS patients and healthy controls in both thermal and pressure pain thresholds as well as mechanical detection thresholds.
In conclusion, heightened nerve mechanosensitivity was present in over half of patients with NSNAP. Our data suggest that NSNAP presents as a spectrum with some patients showing signs suggestive of a minor nerve dysfunction.

Knowledge of the small-scale nutrient status of arable land is an important basis for optimizing fertilizer use in crop production. A mobile field laboratory opens up the possibility of carrying out soil sampling and nutrient analysis directly on the field. In addition to the benefits of fast data availability and the avoidance of soil material transport to the laboratory, it provides a future foundation for advanced application options, e.g. a high sampling density, sampling of small sub-fields or dynamic adaptation of the sampling line during field sampling. An innovative key component is the NUTRI-STAT ISFET sensor module. It measures values for the ions "NO3- ”, “H2PO4- " and "K+ " as well as the pH. The ISFET sensor module was specially developed for soil nutrient analysis. The phosphorus measurement was further developed for the project "soil2data". First results from the ISFET sensor module show a measurement signal settling time of significantly less than 100 seconds and a further consistent stable measurement signal. The measurement signal dynamics of approx. 58 mV per factor 10 of concentration change is given for the measured variables pH and K+. For the measured quantities of NO3- and H2PO4- , the measurement signal dynamics are lower.
Soil versus foliar iodine fertilization as a biofortification strategy for field-grown vegetables
(2015)
Iodine (I) biofortification of vegetables by means of soil and foliar applications was investigated in field experiments on a sandy loam soil. Supply of iodine to the soil in trial plots fertilized with potassium iodide (KI) and potassium iodate directly before planting (0, 1.0, 2.5, 7.5, and 15 kg I ha-1) increased the iodine concentration in the edible plant parts. The highest iodine accumulation levels were observed in the first growing season: In butterhead lettuce and kohlrabi the desired iodine content [50–100 μg I (100 g FM)-1] was obtained or exceeded at a fertilizer rate of 7.5 kg IO3--I ha-1 without a significant yield reduction or impairment of the marketable quality. In contrast, supplying KI at the same rate resulted in a much lower iodine enrichment and clearly visible growth impairment. Soil applied iodine was phytoavailable only for a short period of time as indicated by a rapid decline of CaCl2-extractable iodine in the top soil. Consequently, long-term effects of a one-time iodine soil fertilization could not be observed. A comparison between the soil and the foliar fertilization revealed a better performance of iodine applied aerially to butterhead lettuce, which reached the desired iodine accumulation in edible plant parts at a fertilizer rate of 0.5 kg I--I ha-1. In contrast, the iodine content in the tuber of sprayed kohlrabi remained far below the targeted range. The results indicate that a sufficient spreading of iodine applied on the edible plant parts is crucial for the efficiency of the foliar approach and leafy vegetables are the more suitable target crops. The low iodine doses needed as well as the easy and inexpensive application may favor the implementation of foliar sprays as the preferred iodine biofortification strategy in practice.
Spinach is a nitrogen (N)-demanding crop characterized by a shallow root architecture. Especially in the first weeks after sowing, significant N uptake is limited to the uppermost few centimetres of the soil. However, base fertilization is usually based on the soil mineral N (Nmin) concentration in the upper 30 cm. Therefore, the objective of this study was to examine whether the soil sample depth for calculating the base N fertilization can be reduced to the 0-15 cm layer. In seven field trials, conducted during spring, summer and autumn seasons, either a low or high base fertilization dose was applied at sowing. Until top dressing, soil samples were frequently taken in the upper 0-15 and 15-30 cm layers to determine the average Nmin concentration in each layer. Top dressing was applied when the first true leaves had unfurled. With this fertilizer application, the total N supply was aligned between both treatments based on the Nmin concentration in the upper 30 cm of the soil. Aboveground fresh and dry masses were determined after reaching a fresh mass yield of 15-20 t ha‑1 and related to the mean Nmin concentration in the first 3 to 4 weeks of cultivation between sowing and top dressing. It was shown that the Nmin concentration in the upper 0-15 cm of the soil highly reflects the base fertilization rate. By contrast, the Nmin concentration in the 15-30 cm layer remained unaffected. However, the Nmin concentration of both top soil layers can affect fresh and dry mass yield at harvest. Therefore, the entire 0-30 cm soil layer should be considered when calculating the base N fertilization rate in field-grown spinach. Measurements revealed that spinach fresh and dry masses were increased until the N availability of between 54 and 59 kg ha‑1 (0-30 cm) was reached at the seedlings stage, respectively.
The break-up of the Soviet Union in 1991 triggered cropland abandonment on a continental scale, which in turn ledto carbon accumulation on abandoned land across Eurasia. Previous studies have estimated carbon accumulationrates across Russia based on large-scale modelling. Studies that assess carbon sequestration on abandoned land basedon robust field sampling are rare. We investigated soil organic carbon (SOC) stocks using a randomized samplingdesign along a climatic gradient from forest steppe to Sub-Taiga in Western Siberia (Tyumen Province). In total, SOCcontents were sampled on 470 plots across different soil and land-use types. The effect of land use on changes in SOCstock was evaluated, and carbon sequestration rates were calculated for different age stages of abandoned cropland.While land-use type had an effect on carbon accumulation in the topsoil (0–5 cm), no independent land-use effectswere found for deeper SOC stocks. Topsoil carbon stocks of grasslands and forests were significantly higher thanthose of soils managed for crops and under abandoned cropland. SOC increased significantly with time sinceabandonment. The average carbon sequestration rate for soils of abandoned cropland was 0.66 Mg C ha1yr1(1–20 years old, 0–5 cm soil depth), which is at the lower end of published estimates for Russia and Siberia. Therewas a tendency towards SOC saturation on abandoned land as sequestration rates were much higher for recentlyabandoned (1–10 years old, 1.04 Mg C ha1yr1) compared to earlier abandoned crop fields (11–20 years old,0.26 Mg C ha1yr1). Our study confirms the global significance of abandoned cropland in Russia for carbonsequestration. Our findings also suggest that robust regional surveys based on a large number of samples advancemodel-based continent-wide SOC prediction.
This chapter examines the integration of Sustainable Development Goal 5 (SDG 5) into identity-based brand management by focusing on Dove’s brand management as a case study. The Dove “Real Beauty” campaign highlights the potential for brands to address gender equality and female empowerment by aligning with pro-female and feminist principles. A narrative literature review shows how the components of identity-based brand management have been observed in scholarly discussions. Despite mixed responses and criticisms, Dove initiated important conversations around beauty standards and gender equality. The chapter emphasizes the need for authenticity, sensitivity, and continuous improvement in integrating SDG 5 into brand management while acknowledging the potential risks and limitations of consumerist therapy and false hopes. Future research could therefore explore diverse brands, industries, and cultural contexts, as well as the role of intersectionality in identity-based brand management.

Small-fiber neuropathy and pain sensitization in survivors of pediatric acute lymphoblastic leukemia
(2018)
Background:
Chemotherapy-induced Peripheral Neuropathy (CIPN) of large-fibers affects up to 20% of survivors of pediatric acute lymphoblastic leukemia (ALL). We aimed to describe small-fiber toxicity and pain sensitization in this group.
Methods:
In a cross-sectional, bicentric study we assessed 46 survivors of pediatric ALL (Mean age: 5.7 ± 3.5 years at diagnosis, median 2.5 years after therapy; males: 28). Inclusion criteria: ≥6 years of age, ≥3 months after last administration of Vincristine, and cumulative dose of Vincristine 12 mg/m2. We used a reduced version of the Pediatric-modified Total Neuropathy Score (Ped-mTNS) as bedside test and Quantitative Sensory Testing (QST) for assessment of small- and large-fiber neuropathy as well as pain sensitization. We employed Nerve Conduction Studies (NCS) as the most accurate tool for detecting large-fiber neuropathy.
Results:
Fifteen survivors (33%) had abnormal rPed-mTNS values (≥4 points) and 5 survivors (11%) reported pain. In QST, the survivor group showed significant (p < 0.001) inferior large-fiber function and pain sensitization when compared to healthy matched peers. We identified deficits of vibration in 33 (72%) and tactile hypoesthesia in 29 (63%), hyperalgesia to blunt pressure in 19 (41%), increased mechanical pain sensitivity in 12 (26%) and allodynia in 16 (35%) of 46 survivors. Only 7 survivors (15%) had pathologic NCS.
Conclusion:
QST is a sensitive tool that revealed signs of large-fiber neuropathy in two thirds, small-fiber neuropathy and pain sensitization in one third of survivors. Prospective studies using QST in pediatric oncology may help to elucidate the pathophysiology of small-fiber neuropathy and pain sensitization as well as their relevance for quality of survival.
Background
The population-based mammography screening program (MSP) was implemented by the end of 2005 in Germany, and all women between 50 and 69 years are actively invited to a free biennial screening examination. However, despite the expected benefits, the overall participation rates range only between 50 and 55 %. There is also increasing evidence that belonging to a vulnerable population, such as ethnic minorities or low income groups, is associated with a decreased likelihood of participating in screening programs. This study aimed to analyze in more detail the intra-urban variation of MSP uptake at the neighborhood level (i.e. statistical districts) for the city of Dortmund in northwest Germany and to identify demographic and socioeconomic risk factors that contribute to non-response to screening invitations.
Methods
The numbers of participants by statistical district were aggregated over the three periods 2007/2008, 2009/2010, and 2011/2012. Participation rates were calculated as numbers of participants per female resident population averaged over each 2-year period. Bayesian hierarchical spatial models extended with a temporal and spatio-temporal interaction effect were used to analyze the participation rates applying integrated nested Laplace approximations (INLA). The model included explanatory covariates taken from the atlas of social structure of Dortmund.
Results
Generally, participation rates rose for all districts over the time periods. However, participation was persistently lowest in the inner city of Dortmund. Multivariable regression analysis showed that migrant status and long-term unemployment were associated with significant increases of non-attendance in the MSP.
Conclusion
Low income groups and immigrant populations are clustered in the inner city of Dortmund and the observed spatial pattern of persistently low participation in the city center is likely linked to the underlying socioeconomic gradient. This corresponds with the findings of the ecological regression analysis manifesting socioeconomically deprived neighborhoods as risk factors for low attendance in the MSP. Spatio-temporal surveillance of participation in cancer screening programs may be used to identify spatial inequalities in screening uptake and plan spatially focused interventions.
Recent real-time networking developments have enabled ultra reliability, very low latency and high data rates in wired networks. Wireless networking developments have also shown that they can achieve very high data rates with consistency, but they still lack in providing ultra reliability and extremely low latency. Time Sensitive Networking (TSN) developments have brought these capabilities in Industry automation and Automotive industry too. Although TSN is standardized for wired networks for a long time, for wireless networks it will be standardized within the IEEE 802.11be standard for Wi-Fi and 3GPP Release 17 for 5G in the near future. This paper provides an overview of TSN in wired and wireless networks with the aim of comparing different simulators and presenting their offered functionality and shortcomings. These tools can be used to make oneself familiar with TSN algorithms, standards, and for the development and testing of time sensitive networks. Afterwards, the paper discusses open research questions for using TSN over wireless networks.
SimBO is a flexible framework for optimizing discrete event-driven simulations (DES) using sequential optimization algorithms. While specifically designed for Bayesian Optimization (BO) in the context of DES, SimBO can be applied to any black-box problem with other optimization algorithms. The framework consists of four encapsulated components - the black-box problem, the sequential optimization algorithm, a database for experiment configuration and results, and a web-based graphical user interface - that communicate via well-defined interfaces. Each component can be run in different environments, allowing for cooperation between different hardware- and software configurations. In our research context, SimBO’s architecture enabled BO algorithms to be run on a high-performance cluster with GPU support, while the simulation is executed on a local Windows machine using the Simio simulation software. The framework’s flexibility also makes it suitable for evolving from a research-focused tool to a production-ready, cloud-based optimization tool for modern algorithms.
Apps have been attested to empower patients regarding disease self-management through numerous studies. However, it is still unclear what factors determine the perception of patients whether an app is a useful tool for this purpose. A multiple regression model that was informed by the Technology Acceptance Model (TAM 2) was tested based on the answers of 235 app users with Diabetes type 1 or 2. The model accounted for 59.2% of the variance of the perceived degree of self-management. Factors belonging to the relevance-usefulness-quality complex as well as factors reflecting the patient’s self-control were found to be significant in the model. Patient demographics, i.e. age, gender, app experience and type of Diabetes did not play any significant role. In conclusion, this study raises the question whether apps should be designed to strengthen self-management in the sense of self-control (e.g. own measurements, diary) as opposed to guiding and advice giving.
