Osnabrück’s so called “Green Fingers” – eleven landscape corridors reaching from the inner city into the region – structure the regional metropolis’ urban pattern. They supply the city centre with fresh air, serve as recreational destinations for the city’s inhabitants and provide space for close to the city agriculture and forestry. First defined in 1926, the Green Fingers have since been part of various planning documents and programs. However, these open spaces have been diminished bit by bit over time. The city’s growing need for land to build on had its impact just like the development of major traffic routes. On the one hand a lively debate has emerged: the Green Finger’s qualities, their ecological, aesthetical and cultural significance become increasingly important. Yet on the other hand decision makers still tend to put greenfield building activity first. A lot of efforts in striving for inner development are undermined by the ever growing demand for space. The urban sprawl continues, although various kinds of sanctuaries have been added to the urban and landscape planners’ equipment. The growing urban framework with its semidetached and single family houses does not come to a halt.
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.
Chitin is an abundant waste product from shrimp and mushroom industries and as such, an appropriate secondary feedstock for biotechnological processes. However, chitin is a crystalline substrate embedded in complex biological matrices, and, therefore, difficult to utilize, requiring an equally complex chitinolytic machinery. Following a bottom-up approach, we here describe the step-wise development of a mutualistic, non-competitive consortium in which a lysine-auxotrophic Escherichia coli substrate converter cleaves the chitin monomer N-acetylglucosamine (GlcNAc) into glucosamine (GlcN) and acetate, but uses only acetate while leaving GlcN for growth of the lysine-secreting Corynebacterium glutamicum producer strain. We first engineered the substrate converter strain for growth on acetate but not GlcN, and the producer strain for growth on GlcN but not acetate. Growth of the two strains in co-culture in the presence of a mixture of GlcN and acetate was stabilized through lysine cross-feeding. Addition of recombinant chitinase to cleave chitin into GlcNAc2, chitin deacetylase to convert GlcNAc2 into GlcN2 and acetate, and glucosaminidase to cleave GlcN2 into GlcN supported growth of the two strains in co-culture in the presence of colloidal chitin as sole carbon source. Substrate converter strains secreting a chitinase or a β-1,4-glucosaminidase degraded chitin to GlcNAc2 or GlcN2 to GlcN, respectively, but required glucose for growth. In contrast, by cleaving GlcNAc into GlcN and acetate, a chitin deacetylase-expressing substrate converter enabled growth of the producer strain in co-culture with GlcNAc as sole carbon source, providing proof-of-principle for a fully integrated co-culture for the biotechnological utilization of chitin.
High levels of meat consumption are increasingly being criticised for ethical, environmental, and social reasons. Plant-based meat substitutes have been with reservations identified as healthy sources of protein in comparison to meat. This alternative offers several social, environmental, and probably health benefits, and it may play a role in reducing meat consumption. However, there has been a lack of research on how specific meat substitute attributes can influence consumers to replace or partially replace meat in their diets. Research has demonstrated that, in many countries, consumers are highly attached to meat. They consider it to be an essential and integral element of their daily diet. For the consumers that are not interested in vegan or vegetarian alternatives to meat, so-called meathybrids could be a low-threshold option for a more sustainable food consumption behaviour. In meathybrids, only a fraction of the meat product (e.g., 20% to 50%) is replaced with plant-based proteins. In this paper, the results of an online survey with 500 German consumers are presented with a focus on preferences and attitudes relating to meathyrids. The results show that more than fifty percent of consumers substitute meat at least occasionally. Thus, approximately half of the respondents reveal an eligible consumption behaviour with respect to sustainability and healthiness to a certain degree. Regarding the determinants of choosing either meathybrid or meat, it becomes evident that the highest effect is exerted by the health perception. The healthier meathybrids are perceived, the higher is the choice probability. Thus, this egoistic motive seems to outperform altruistic motives, like animal welfare or environmental concerns, when it comes to choice for this new product category.
Current discussions about the concept of nutritional sustainability show a high complexity of this topic leading to many different definitions. Regarding communication issues of nutritional sustainability between actors of food chains this complexity should be reduced. One opportunity to tackle these challenges of reducing complexity might be the concept of ingredient branding. Therefore, the aim of this mini-review is the identification of conditions for ingredient branding application as a communication strategy for nutritional sustainability which might overcome challenges in communicating the complexity between the different stakeholders of supply chains. In doing so, the specific case of agrifood chains is discussed based on the selected characteristics of globalization, increasing consumer demands, foods incorporating credence attributes and price. Along the agrifood chain, a sourcing strategy reflecting nutritional and sustainable aspects might lead to an ingredient branding strategy implying a brand policy for a special ingredient within the final product which is an important component but cannot be clearly recognized by the user. A “nutritional sustainability inside” strategy should reflect the multifaceted information along the agrifood chain and should be based on standardized criteria for nutritional sustainability.
Integration of nutritional and sustainable aspects is a complex task tackled by a few scientific concepts. They include multiple dimensions and functions of food systems trying to provide solutions for harmonic co-evolution of humanity and planet Earth. “Nutritional Sustainability” is differentiated from other concepts which combine nutrition and sustainability as it not only sets environmental sustaining capacity as a baseline level for balanced nutrition, but also aims for the search of food system driving nodes. It does not aim for the support of solutions of producing enough or more food for increasing population (sustainable nutrition), neither does it contradict other similar concepts [sustainable nutrition security, nutritional life cycle assessment (LCA)]. However, it calls for more definite estimation of the carrying capacity of the environment on personal, local, and national levels for the development of more efficient solutions of nutrition balanced in the limits of environmental carrying capacity. The review is providing a few examples of advances in nutritional science (personalized nutrition, nutrigenetics), food technology (personalized food processing, food ecodesign), and food complex systems (artificial intelligence and gut microbiome), which have a great potential to progress sustainable food systems with Nutritional Sustainability set as a guiding concept.
Functional foods are still of increasing interest among the scientific community. Based on the extensive literature about functional foods, four main research areas can be identified: functional food innovation (1); the scientific background of the health benefits of functional foods (2); the regulation of functional foods (3); and consumer acceptance of functional foods (4). These research areas are not detached from each other, and each presents a consumer perspective. Although multifaceted studies focus on consumer acceptance of functional foods, literature regarding a structured framework of the determinants of functional food acceptance is limited. The aim of this review is to provide the reader with an overview of the recent literature on consumer attitudes towards functional foods and with an extensive structured framework of the determinants of functional food acceptance and their intertwined relationships. The scientific literature discusses a plethora of determinants of consumer acceptance of functional foods. These determinants can be categorized into consumer and market attributes, which show interwoven relationships with each other. On the one hand, consumer attributes are widely discussed in the literature, while on the other hand structured analyses of the market perspective are inadequately represented. Additionally, the ongoing development of new scientific findings regarding health benefits of different functional ingredients leads to a large amount of new functional food products in the market. Consequently, the research area of functional foods and in particular consumer acceptance of functional food innovation will remain an important research field in the coming years.
Convergence processes are based on the activity of distinct industry sectors showing cross-industry collaborations. The aim of this paper is to analyze cross-industry collaborations between the food and pharmaceutical sectors in the convergence area of functional foods. Selected companies from food (Nestlé/Danone) and pharmaceutical (Martek/Bayer HealthCare) sectors are analyzed using the determinants of motivation and industrial scope. The analysis shows that food companies are more active in cross-industry collaborations than pharmaceutical companies. The latter are more active at the front-end of the value chain focusing on research and development, and delivering their ingredients to food companies that due to their higher expertise in consumer marketing launch the products. While the first cross-industry collaborations were based on an exploration motivation, those that follow focus on exploitation. Acquisitions and licensing agreements are dominant in inside-out and outside-in processes, whereas strategic alliances and joint ventures are based on a coupled process between the food and pharmaceutical sectors.
The aim of this paper is to advance the research on innovation at the pharma-nutrition interface by analysing the three steps of science, technology and market convergence in the area of probiotics using a life cycle perspective. Results from a bibliometric analysis drawing upon 8245 scientific publications, 2082 patents and 1357 news reports focussing on product launch announcements from 1990 up to 2009 indicate that the proposed curve shapes of the life cycles in the theory based framework can be transferred to the case of probiotics. There is a time shift considering the life cycles showing the same activities of the industrial sectors at different moments of time. The food sector dominates the field of probiotics by driving science, technology and market convergence showing earlier activities in scientific publications, patents as well as product launches, while presenting a higher clockspeed between the different life cycle phases. While the food sector dominates product launches for food products containing probiotics, the pharmaceutical sector dominates the product launches of the supplement market. In addition, a clear trend towards industry convergence can be identified by the growing number of cross-industry activities.
The relevance of cross-industry innovation has increased in recent decades with a growing number of inter-industry fields emerging on the borderline between formerly distinct industries. The aim of this paper is to analyse industry convergence in four probiotics innovation value chains based on the following indicators: cross-industry relationships along the innovation value chain as well as knowledge, technological, regulatory and competence convergence. In so doing, the study delivers a framework of indicators for scrutinising industry convergence processes. In order to identify industry convergence, we analyse companies in the converging area of foods and drugs based on products containing the four bacteria strains: Lactobacillus caseii DN 114001, Bifidobacterium lactis Bb12, Lactobacillus acidophilus LA5 and Lactobacillus rhamnosus. Hence, the commercial availability of the strains on the market serves as a selection criterion. Altogether 12 companies stemming from four industrial backgrounds, food and agriculture (5), pharmaceutics (5), chemistry (1) and personal care (1), as well as one research organisation are identified. Cross-industry relationships occur along the innovation value chains of the four strains. Clear signs of knowledge and technological convergence are found as companies are not only publishing and patenting in the usual area of their own industrial field but also in the area of other industrial fields. Companies with different industrial backgrounds show activities in obtaining health claims indicating regulatory convergence. Companies' competence bases seem to converge as companies with different industrial backgrounds are involved in acquisitions, licencing agreements and strategic alliances (competence convergence). We contribute to the existing body of literature by assessing industry convergence from an innovation value chain perspective with a set of indicators reflecting the intensity of industry convergence. This framework of indicators stemming from literature has not yet been used in a combined comprehensive analysis. Furthermore, we tried to show the characteristics of strategic types driving industry convergence in probiotics.
What determines ingredient awareness of consumers? : A study on ten functional food ingredients
(2014)
Given the importance of consumer awareness of functional food ingredients for healthy food choices, the aim of this study is to explore consumers’ ingredient awareness and the determinants which influence the awareness about functional food ingredients.
A sample of 200 German consumers was interviewed via CATI (computer aided telephone interview) during September 2011. The participants have been asked about their specific awareness regarding to ten functional food ingredients. Likewise, determinants like health status and health motivation have been assessed and their influence on the construct “consumers’ ingredient awareness” has been tested by employing structural equation modeling.
The study shows that consumers’ ingredient awareness varies throughout the sample. Overall it can be stated, that 19% of consumer awareness about functional food ingredients is explained through the described model based on the following predictors: age, educational level, health status, health motivation and information strategies. Among these factors, consumers’ health motivation seems to have the highest relevance to explain consumer awareness. But also the determinants information strategies as well as the education show a significant influence on consumers’ ingredient awareness. As health motivation shows the highest impact on consumers’ ingredient awareness this study underlines the importance of prevention propensity for healthy food choices.
In the past few years, studies have been carried out to record and analyse the consumer behaviour of manual dishwashing. Manual dishwashing in households is performed in many ways that influence the use of resources. Furthermore, knowledge has been gained on the basis of experiments on how to optimize the use of resources in manual dishwashing. Optimization here means achieving the best possible cleaning performance with a minimum input of resources. This experimental knowledge, combined with the experience of everyday life, was transferred into Best Practice Tips.
The aim of this study is to verify whether it is possible to save resources while applying these Best Practice Tips in comparison with the consumers' previous behaviour.
In a laboratory study, 53 consumers from Europe (23 Germans, 30 other Europeans) were asked to apply the Best Practice Tips while washing up 12 place settings of dishes. The data gained were compared with that of previous studies recording consumers' everyday behaviour while washing up the same amount of dishes. The sample consisted of 113 European consumers and the sample of the second study consisted of 60 Europeans.
On average, the 53 test participants applying the Best Practice Tips used around 60% less water, 70% less energy and 30% less detergent compared with the average everyday behaviour the other subjects used. Additionally, they achieved a slightly better cleaning result. An evaluation questionnaire showed that the Best Practice Tips were, in general, highly accepted; however, some concerns were given about their exact application in everyday life. Because of the wide variation of washing-up habits and resource consumption among individuals, the confidence intervals of the studies are rather large. The results should therefore be seen as tendencies on how resource savings are possible when people are trained how to optimize resources in manual dishwashing. Nevertheless, this study should be the basis for further ones in which the learning is verified in everyday life and over a longer period of time.
USA als Vorbild?
(2013)
Das Gesundheitswesen in den Vereinigten Staaten bekannt für Spitzenforschung und High-end-Medizin. Auch für das Krankenhausmanagement lohnt der Blick über den großen Teich. Unsere Autorin hat im Rahmen eines Forschungsaufenthalts in New York Interviews mit Geschäftsführern und Mitarbeitern an verschiedenen Kliniken geführt. Ergebnis: In puncto Kostenmanagement zeigt sich, dass die Ressourceneffizienz vergleichsweise wenig ausgeprägt ist, die Rahmenbedingungen für eine hohe Prozesseffizienz hingegen vielfach gegeben sind.
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.
Evaporation from growing media significantly contributes to increasing the humidity in greenhouses. The effects of a pine bark mulch cover on substrate evaporation was evaluated with different pot experiments. The obtained data have been tested within the water balance model HYDRUS-1D, which was originally developed for mineral soils. Objective of this study was to test the performance of HYDRUS-1D to describe evaporation in plant containers and to evaluate the effect of pine bark as cover layer or layers within growing media. Application of pine bark in combination with peat substrate reduced evaporation up to 50% depending on position, thickness of mulch layer and water content of the substrate. The highest reduction in evaporation was measured in a dry substrate which is covered with 4 cm pine bark. The HYDRUS-1D model describes evaporation from growing media in combination with layers of pine bark correctly as long as hysteresis of the water retention curve and vapor flow is considered in the model.
Eine Woche vor Weihnachten 2008 startete die OMT-DVMT-Ausbildung 2008 – 2010 mit einem Kurswochenende und einer Supervision in München. Vor den 8 Studenten lagen 2 Jahre Ausbildung. Die Inhalte und die zu erbringenden Leistungen waren zwar bekannt, aber wie intensiv die Ausbildung sein sollte, zeigte sich erst im Laufe der Zeit. Da alle Teilnehmer im Berufsleben standen und durchaus auch ein Privatleben mit Kindern hatten, war die Fähigkeit zum Spagat zwischen der Weiterbildung und dem Rest des Lebens gefordert.
Langeweile kam nie auf, das Dozententeam lehrte und vertiefte übersichtlich wissenschaftliche und klinische Inhalte. Thomas Schöttker-Königer und Fiona Morrison referierten an mehreren Wochenenden über Evidence-based Medicine (EBM) und Statistik. Den Satz „Traue nur der Statistik, die du selber gefälscht hast”, kann mittlerweile jeder der Studenten gut nachvollziehen, zu viele Beispiele gibt es dazu in veröffentlichten Studien.
Ralf Schesser und Nina Gärtner-Tschacher vermittelten weiterführende und detaillierte Inhalte zum Schmerzmanagement und der Klassifikation von Rückenschmerzen. Abgerundet wurde die Ausbildung durch den ärztlichen Unterricht von Dr. Hans Knorr, einem Medical-Screening-Kurs von Debra Shirley von der University of Sydney und 4 intensiven Supervisionen, die Jan Herman van Minnen, Thomas Horre, Renate Wiesner, Trisha Davies-Knorr, Marc van Liebergen und John Langendoen-Sertel betreuten.
Ende Oktober fand dann die Abschlussprüfung in München statt. Die zu prüfenden Fächer Ärztlicher Unterricht, Verteidigung der Abschlussarbeit, Patientenbehandlung mit anschließender Diskussion und Technikprüfung verlangten den Studenten noch einmal hohe Konzentration und Geduld ab. Alle Prüfungen wurden am selben Tag von 8.00 bis 18.00 Uhr abgehalten. Schlussendlich konnte bei mehreren Gläsern alkoholhaltiger Erfrischungsgetränke ein überaus positives Resümee des mit Höhen und Tiefen gepflasterten Wegs zum OMT-Examen gezogen werden.
Die OMT-Ausbildung macht deutlich, wie wichtig und aktuell die Bedeutung der Verknüpfung von Wissenschaft und Klinik in der täglichen Arbeit ist. Sie sorgt für eine hochwertige Patientenversorgung und fördert die Qualität der Physiotherapie. Es ist zu hoffen, dass noch mehr Physiotherapeuten diesen Weg wählen und sich hochwertig weiterqualifizieren.
Naturentfremdung
(2018)
Kreditfinanzierungen im Krankenhauswesen werden u. a. aufgrund bestehender Investitionsstaus und aktueller Herausforderungen aus dem Umgang mit der COVID-19-Pandemie weiter an Bedeutung gewinnen. Der folgende Beitrag fasst die Ergebnisse einer Anfang 2019 veröffentlichten Dissertation zusammen: eine Bestandsaufnahme und Analyse der heutigen Finanzkommunikation zwischen Krankenhaus und Kreditinstitut, die bestehende Problemfelder und kritische Faktoren der Finanzkommunikation identifiziert und Handlungsempfehlungen für beide Parteien zur Verbesserung der Finanzkommunikation und zur Begegnung der Herausforderungen zukünftiger Kreditfinanzierungen ableitet.
Personalsicherung ist eine gesundheitspolitische und
krankenhausmanagementbezogene Aufgabe. Die Verbindung zwischen Politik und Management kann über geeignete externe, politische Rahmenbedingungen und interne, managementbezogene Struktur- und Steuerungsmaßnahmen hergestellt werden. Dabei stellt sich zur Zeit die Frage, inwieweit über Gesetze und Verordnungen Vorgaben zum Personalbedarf gemacht werden sollen. Aktuelle Diskussionen zum Spannungsfeld zwischen politischer Gestaltung und Freiräumen des Managements bis hin zur Frage, inwieweit der Personalbedarf in einem Preissystem adäquat abgebildet werden kann, bilden den Gegenstand dieses Beitrags.
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.
Krankenhauskultur – eine Frage der Entscheidung : Warum gelebte Werte und Normen entscheidend sind

Führung und Controlling : Ansatzpunkte zur Gestaltung der Beziehung von Manager und Controller
(2021)
Die Wirkkraft des Controllings setzt eine stabile, partnerschaftliche Zusammenarbeit von Manager und Controller voraus, die jedoch in der Praxis häufig nicht anzutreffen ist. Vielmehr ist die Arbeitsbeziehung durch unterschiedliche Positionen zum Führungsverständnis (Führung braucht Freiräume vs. Führung muss systematisiert und quantifiziert werden) und durch unterschiedliche Erwartungen an die Aufgabenerfüllung (Rollenbild des Controllers und des Managers) gekennzeichnet. Die unterschiedlichen Standpunkte und die daraus resultierenden dysfunktionalen Verhaltensweisen (z.B. Slack, Manipulation, Ressortegoismus) bzgl. des Controllings (z.B. keine Nachfrage nach oder Zurückhaltung von Informationen, Widerstand) führen zu Reibungsverlusten, denen entgegenzuwirken ist.
Je reibungsloser das Zusammenspiel von Management und Controlling, desto effektiver können die Entscheidungsprobleme des Krankenhausmanagements gelöst werden. In der Praxis treten allerdings regelmäßg Reibungsverluste in der Zusammenarbeit auf. Die Arbeitsbeziehung zwischen Controller und Manager ist häufig konfliktgeladen und wenig partnerschaftlich. Ursächlich für die negative Dynamik der Beziehung sind unterschiedliche Führungsentwürfe und Rollenbilder zum Controlling. Der Beitrag widmet sich den Anforderungen und der Struktur eines Controllings im Krankenhaus, das den Besonderheiten der Expertenorganisation gerecht werden kann.
Hintergrund
Sprunggelenksverletzungen (SGV) sind die häufigsten Verletzungen des muskuloskeletalen Systems. Neben Schmerz, Schwellung und Funktionseinschränkung werden Zusammenhänge zwischen einem Sprunggelenkstrauma und Veränderungen am Becken bzw. Sakroiliakalgelenk (SIG) diskutiert. In der vorliegenden Studie wird geprüft, ob Wechselwirkungen von SGV und Veränderungen am Becken bzw. SIG bestehen.
Material und Methoden
In dieser Querschnittsstudie ohne Verblindung wurden 18 Probanden mit SGV und 22 gesunde Probanden am Becken und SIG untersucht. Der Zustand nach der SGV wurde anhand des FAAM-G-Fragebogens ermittelt. Die Evaluation der Beckenposition erfolgte mit Photometrie. Dabei wurden die Referenzpunkte SIAS und SIPS zueinander verglichen. Am SIG erfolgten Schmerzprovokationstests, um Veränderungen am SIG zu ermitteln. Die in beiden Gruppen erhobenen Daten wurden statistisch ausgewertet und verglichen.
Ergebnisse
Der funktionelle Zustand der Sprunggelenke unterschied sich zwischen der Kontrollgruppe und der Experimentalgruppe signifikant. Die Unterschiede bei den photometrischen Ergebnissen waren für die Beckensymmetrie nicht signifikant (SIAS p = 0,426; SIPS p = 0,779). Hinsichtlich der Schmerzhaftigkeit des SIG zeigte sich ebenfalls kein signifikanter Unterschied (p = 0,477).
Schlussfolgerung
Es konnten keine Positionsveränderungen des Beckens infolge eines Sprunggelenktraumas beobachtet werden. Auch zeigten sich keine Assoziationen zwischen SGV und Becken- bzw. SIG-Position.
Vergleich der Effekte eines funktionellen Stabilisations- mit einem Standardtraining auf Schmerz, Funktion, Kinematik der unteren Extremität und des Rumpfes, Ausdauerfähigkeit der Rumpfmuskulatur und der Kraft der exzentrischen Kniegelenks- und Hüftmuskultur bei Frauen mit patellofemoralen Schmerzen.
Biomechanische Analysen sind in der Lage, menschliche Bewegungen valide und umfassend zu erfassen und auszuwerten. Neben den beiden großen Bereichen Kinetik und Kinematik bietet die Elektromyografie (EMG) eine zuverlässige Möglichkeit, die neuromuskuläre Aktivität zu analysieren. Mithilfe des EMG können neuromuskuläre Parameter erhoben werden, die präzise Aussagen beispielsweise zur inter- und intramuskulären Koordination, der Muskelfaserverteilung, des Ermüdungsverhaltens oder des Timings zulassen.
Für verlässliche Daten sind im klinischen Setting jedoch einige wichtige Faktoren zu berücksichtigen. Diese sind von großer Bedeutung und sollten vor einer Analyse beachtet werden. Daneben hängt ein effektiver Einsatz des EMG im klinischen Setting von der Integration in den Clinical-Reasoning-Prozess ab. Die jeweilige individuelle Patientensituation benötigt eine klare Fragestellung. Dazu kann auf ein Ebenenmodell aufgebaut werden, welches die biomechanischen Steuerungsgrößen in der klinischen Anwendung berücksichtigt.
Der Artikel stellt die physiologischen Grundlagen der Elektromyografie, die Einflüsse von Verletzungen auf die Muskelfaserzusammensetzung, die grundlegende Signalverarbeitung und Dateninterpretation, ein Ebenenmodell für die klinische Anwendung sowie Einsatzfelder in der Physiotherapie vor.
Das Forschungsprojekt „Dorfgemeinschaft 2.0“ hat zum Ziel, dem Bedürfnis der Bürger_innen nachzukommen, auch im Alter zu Hause wohnen bleiben zu können. Die Gesundheitsversorgung im ländlichen Raum steht im Mittelpunkt. Hierfür werden regional angepasste Lösungsstrategien anhand des Design Science Ansatzes entworfen und individuelle Wünsche und Bedarfe multiperspektivisch in den Blick genommen. Vier der so entstandenen Versorgungskonzepte werden als nutzerorientierte alltags und gesundheitsbezogene Ansätze vorgestellt. Zudem werden die angedachten Kommunikationsstrukturen und das Zusammenwirken der Konzepte als Versorgungsnetz auf dem virtuellen Dorfmarktplatz beschrieben.
Ziel des Beitrags ist die Identifikation von Problemen, Meta-Anforderungen und Designprinzipien für den Einsatz von Mixed und Virtual Reality Brillen zur Unterstützung nicht-ärztlichen Fachpersonals bei zahnmedizinischen Hausbesuchen. Im Rahmen von zwei Gruppendiskussionen und einem Experteninterview wurden zunächst mögliche Einsatzszenarien identifiziert. Anschließend wurde eine systematische Literaturrecherche in den Datenbanken CINAHL, Business Source Premier und MEDLINE durchgeführt. In der gefundenen Literatur konnten 14 Probleme bei der Anwendung von Mixed und Virtual Reality Brillen identifiziert werden. Darauf basierend wurden 14 Meta-Anforderungen abgeleitet und in fünf Designprinzipien zusammengefasst. Abschließend wurden die Ergebnisse mit den Spezifikationen der Microsoft HoloLens 2 abgeglichen, um eine Eignung für die Unterstützung der geplanten Hausbesuche festzustellen. Zudem wurde ein Umsetzungskonzept skizziert. Die Ergebnisse dienen als wichtige Empfehlungen für die praxisnahe Umsetzung zukünftiger Konzepte bezüglich der Anwendung von Mixed und Virtual Reality Brillen im (zahn-)medizinischen Kontext. Die Literaturrecherche zeigt eine Forschungslücke im Bereich zahnmedizinischer Hausbesuche auf. Die Ergebnisse dieses Beitrags schaffen daher eine solide Basis für die zukünftige Forschung.
Flexibility in planning through frequent amendments. The practice of land use planning in Germany
(2022)
How can formal planning deal with uncertainty and rapid change while maintaining high standards of procedural certainty? This paper, using Germany as an example, examines how municipalities handle this dilemma within their existing planning systems. Municipalities use different approaches, ranging from regular redrafting to comprehensive changes or regular amendments. Amendments and complementary informal plans are important components of flexibility in planning. We argue that the choice to make frequent amendments instead of redrafting the preparatory land-use plan does not necessarily lead to a loss of a city-wide, long-term perspective, provided amendments are prepared and justified using informal concepts.
Bericht über das 35. Symposium der Performing Arts Medicine Association in Snowmass, Colorado
(2018)
Objectives: Among varied challenges of COVID-19, challenges in food and nutrition security world-over are critical. We compared the nutritional policy responses in India and Germany since both countries differ on the Human Development Index, yet both have committed to the G20 common policy response to COVID-19, besides the comparability of two large and heterogeneously populated countries, both having democratic governments.
Methods: Policy research publications were reviewed using qualitative meta-policy approach. We used comparative case-study. Recent food and nutrition policies of G20 nations of India and Germany were evaluated.
Results: India has primarily targeted her public distribution system and Germany has primarily targeted her food markets in order to manage the food and nutrition security in response to COVID-19. Both countries are coordinating additional associated nutritional policies, policies and strategies to effect an integrated sectoral approach to COVID-19 management. Both are using corrective measures of the process management strategies as well. However, the Indian management of micronutrient security for her population has over COVID-19 times acerbated and the German loan management to nutrition and agricultural small-scale industry appears to be functioning sub-optimally.
Conclusions: Our analysis indicates both India and Germany have responded to COVID-19 in a timely and appropriate manner regarding the food and nutrition security measures. Even so not all measures employed to tackle COVID-19 food and nutrition security have been effectively implemented, It appears, that both countries are using integrated policy in their nutrition and food security response to COVID-19.
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.
The development of augmented reality glasses is still ongoing and faces barriers in diffusion and concerns about their impact on users, organizations and society. The study aims to find sufficient solutions for this struggling digital innovation and to provide guidance for the implementation of augmented reality glasses in design-oriented projects. During a 3-year consortium research, acceptance and privacy have been identified as major phenomena that influence the adoption of augmented reality glasses in the logistics domain. To forge ahead digital innovation research, the focus of the presented research lies on the diffusion of this technology with design knowledge for the development of augmented reality glasses-based systems. Evidence and artifacts contribute to the still limited knowledge of system design based on augmented reality glasses from a domain-specific instantiation and an implementation framework.

Europe's freshwater biodiversity under climate change: distribution shifts and conservation needs
(2014)
Aim
To assess the future climatic suitability of European catchments for freshwater species and the future utility of the current network of protected areas.
Location
Europe.
Methods
Using recently updated catchment-scale species data and climate projections from multiple climate models, we assessed the climate change threat by the 2050s for 1648 European freshwater plants, fishes, molluscs, odonates, amphibians, crayfish and turtles for two dispersal scenarios and identified hotspots of change at three spatial scales: major river basins, countries and freshwater ecoregions. We considered both common species and the often overlooked rare species. To set our findings within the context of current and future conservation networks, we evaluated the coverage of freshwater biodiversity by Europe's protected area network.
Results
Six per cent of common and 77% of rare species are predicted to lose more than 90% of their current range. Eight fish species and nine mollusc species are predicted to experience 100% range loss under climate change. As the most species-rich group, molluscs are particularly vulnerable due to the high proportion of rare species and their relatively limited ability to disperse. Furthermore, around 50% of molluscs and fish species will have no protected area coverage given their projected distributions.
Main conclusions
We identified the species most at threat due to projected changes in both catchment suitability and representation within the European protected area network. Our findings suggest an urgent need for freshwater management plans to facilitate adaptation to climate change.
The conservation of freshwater ecosystems has lagged behind that of marine and terrestrial ecosystems and often requires the integration of large-scale approaches and transboundary considerations. This study aims to set the foundations of a spatial conservation strategy by identifying the most important catchments for the conservation of freshwater biodiversity in Europe.
Using data on 1296 species of fish, mollusc, odonate and aquatic plant, and the key biodiversity area criteria (species Red List status, range restriction and uniqueness of species assemblages), we identified a network of Critical Catchments for the conservation of freshwater biodiversity. Applying spatial prioritisation, we show how the prioritised network differs from the ideal case of protecting all Critical Catchments and how it changes when protected areas are included, and we also identify gaps between the prioritised network and existing protected areas.
Critical Catchments (n = 8423) covered 45% of the area of Europe, with 766 qualifying (‘trigger’) species located primarily in southern Europe. The prioritised network, limited to 17% of the area of Europe, comprised 3492 catchments mostly in southern and eastern Europe and species targets were met for at least 96% of the trigger species.
We found the majority of Critical Catchments to be inadequately covered by protected areas. However, our prioritised network presents a possible solution to augment protected areas to meet policy targets while also achieving good species coverage.
Policy implications. While Critical Catchments cover almost half of Europe, priority catchments are mostly in southern and eastern Europe where the current level of protection is not sufficient. This study presents a foundation for a Europe-wide systematic conservation plan to ensure the persistence of freshwater biodiversity. Our study provides a powerful new tool for optimising investment on the conservation of freshwater biodiversity and for meeting targets set forth in international biodiversity policies, conventions and strategies.
Climate change is expected to exacerbate the current threats to freshwater ecosystems, yet multifaceted studies on the
potential impacts of climate change on freshwater biodiversity at scales that inform management planning are lacking. The aim of this study was to fill this void through the development of a novel framework for assessing climate
change vulnerability tailored to freshwater ecosystems. The three dimensions of climate change vulnerability are as
follows: (i) exposure to climate change, (ii) sensitivity to altered environmental conditions and (iii) resilience potential.
Our vulnerability framework includes 1685 freshwater species of plants, fishes, molluscs, odonates, amphibians, crayfish and turtles alongside key features within and between catchments, such as topography and connectivity. Several
methodologies were used to combine these dimensions across a variety of future climate change models and scenarios. The resulting indices were overlaid to assess the vulnerability of European freshwater ecosystems at the catchment scale (18 783 catchments). The Balkan Lakes Ohrid and Prespa and Mediterranean islands emerge as most
vulnerable to climate change. For the 2030s, we showed a consensus among the applied methods whereby up to 573
lake and river catchments are highly vulnerable to climate change. The anthropogenic disruption of hydrological
habitat connectivity by dams is the major factor reducing climate change resilience. A gap analysis demonstrated that
the current European protected area network covers <25% of the most vulnerable catchments. Practical steps need to
be taken to ensure the persistence of freshwater biodiversity under climate change. Priority should be placed on
enhancing stakeholder cooperation at the major basin scale towards preventing further degradation of freshwater
ecosystems and maintaining connectivity among catchments. The catchments identified as most vulnerable to climate
change provide preliminary targets for development of climate change conservation management and mitigation
strategies.
The distribution of a species along a thermal gradient is commonly approximated by a unimodal response curve, with a characteristic single optimum near the tempera‐ture where a species is most likely to be found, and a decreasing probability of occur‐rence away from the optimum. We aimed at identifying thermal response curves (TRCs) of European freshwater species and evaluating the potential impact of climate warming across species, taxonomic groups, and latitude. We first applied generalized additive models using catchment‐scale global data on distribution ranges of 577 freshwater species native to Europe and four different temperature variables (the current annual mean air/water temperature and the maximum air/water temperature of the warmest month) to describe species TRCs. We then classified TRCs into one of eight curve types and identified spatial patterns in thermal responses. Finally, we in‐tegrated empirical TRCs and the projected geographic distribution of climate warm‐ing to evaluate the effect of rising temperatures on species’ distributions. For the different temperature variables, 390–463 of 577 species (67.6%–80.2%) were char‐acterized by a unimodal TRC. The number of species with a unimodal TRC decreased from central toward northern and southern Europe. Warming tolerance (WT = maxi‐mum temperature of occurrence—preferred temperature) was higher at higher lati‐tudes. Preferred temperature of many species is already exceeded. Rising temperatures will affect most Mediterranean species. We demonstrated that fresh‐water species’ occurrence probabilities are most frequently unimodal. The impact of the global climate warming on species distributions is species and latitude depend‐ent. Among the studied taxonomic groups, rising temperatures will be most detri‐mental to fish. Our findings support the efforts of catchment‐based freshwater management and conservation in the face of global warming.
Niche-based species distribution models (SDMs) have become an essential tool in conservation and restoration planning. Given the current threats to freshwater biodiversity, it is of fundamental importance to address scale effects on the performance of niche-based SDMs of freshwater species’ distributions. The scale effects are addressed here in the context of hierarchical catchment ordering, considered as counterpart to coarsening grain-size by increasing grid-cell size. We combine fish occurrence data from the Danube River Basin, the hierarchical catchment ordering and multiple environmental factors representing topographic, climatic and anthropogenic effects to model fish occurrence probability across multiple scales. We focus on 1st to 5th order catchments. The spatial scale (hierarchical catchment order) only marginally influences the mean performance of SDMs, however the uncertainty of the estimates increases with scale. Key predictors and their relative importance are scale and species dependent. Our findings have useful implications for choosing proper species dependent spatial scales for river rehabilitation measures, and for conservation planning in areas where fine grain species data are unavailable.
Model-derived relationships between chlorophyll a (Chl-a) and nutrients and temperature have fundamental implications for understanding complex interactions among water quality measures used for lake classification, yet accuracy comparisons of different approaches are scarce. Here, we (1) compared Chl-a model performances across linear and nonlinear statistical approaches; (2) evaluated single and combined effects of nutrients, depth, and temperature as lake surface water temperature (LSWT) or altitude on Chl-a; and (3) investigated the reliability of the best water quality model across 13 lakes from perialpine and central Balkan mountain regions. Chl-a was modelled using in situ water quality data from 157 European lakes; elevation data and LSWT in situ data were complemented by remote sensing measurements. Nonlinear approaches performed better, implying complex relationships between Chl-a and the explanatory variables. Boosted regression trees, as the best performing approach, accommodated interactions among predictor variables. Chl-a–nutrient relationships were characterized by sigmoidal curves, with total phosphorus having the largest explanatory power for our study region. In comparison with LSWT, utilization of altitude, the often-used temperature surrogate, led to different influence directions but similar predictive performances. These results support utilizing altitude in models for Chl-a predictions. Compared to Chl-a observations, Chl-a predictions of the best performing approach for mountain lakes (oligotrophic–eutrophic) led to minor differences in trophic state categorizations. Our findings suggest that both models with LSWT and altitude are appropriate for water quality predictions of lakes in mountain regions and emphasize the importance of incorporating interactions among variables when facing lake management challenges.
Land cover change is a dynamic phenomenon driven by synergetic biophysical and socioeconomic effects. It involves massive transitions from natural to less natural habitats and thereby threatens ecosystems and the services they provide. To retain intact ecosystems and reduce land cover change to a minimum of natural transition processes, a dense network of protected areas has been established across Europe. However, even protected areas and in particular the zones around protected areas have been shown to undergo land cover changes. The aim of our study was to compare land cover changes in protected areas, non-protected areas, and 1 km buffer zones around protected areas and analyse their relationship to climatic and socioeconomic factors across Europe between 2000 and 2012 based on earth observation data. We investigated land cover flows describing major change processes: urbanisation, afforestation, deforestation, intensification of agriculture, extensification of agriculture, and formation of water bodies. Based on boosted regression trees, we modelled correlations between land cover flows and climatic and socioeconomic factors. The results show that land cover changes were most frequent in 1 km buffer zones around protected areas (3.0% of all buffer areas affected). Overall, land cover changes within protected areas were less frequent than outside, although they still amounted to 18,800 km2 (1.5% of all protected areas) from 2000 to 2012. In some parts of Europe, urbanisation and intensification of agriculture still accounted for up to 25% of land cover changes within protected areas. Modelling revealed meaningful relationships between land cover changes and a combination of influencing factors. Demographic factors (accessibility to cities and population density) were most important for coarse-scale patterns of land cover changes, whereas fine-scale patterns were most related to longitude (representing the general east/west economic gradient) and latitude (representing the north/south climatic gradient).

Thermal response curves that depict the probability of occurrence along a thermal gradient are used to derive various species’ thermal properties and abilities to cope with warming. However, different thermal responses can be expected for different portions of a species range. We focus on differences in thermal response curves (TRCs) and thermal niche requirements for four freshwater fishes (Coregonus sardinella, Pungitius pungitius, Rutilus rutilus, Salvelinus alpinus) native to Europe at (1) the global and (2) European continental scale. European ranges captured only a portion of the global thermal range with major differences in the minimum (Tmin), maximum (Tmax) and average temperature (Tav) of the respective distributions. Further investigations of the model-derived preferred temperature (Tpref), warming tolerance (WT = Tmax − Tpref), safety margin (SM = Tpref − Tav) and the future climatic impact showed substantially differing results. All considered thermal properties either were under- or overestimated at the European level. Our results highlight that, although continental analyses have an impressive spatial extent, they might deliver misleading estimates of species thermal niches and future climate change impacts, if they do not cover the full species ranges. Studies and management actions should therefore favor whole global range distribution data for analyzing species responses to environmental gradients.
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.

Mit der Akademisierung von praktischen Gesundheitsberufen stehen die Hochschulen und Universitäten gleichermaßen vor der Herausforderung, Pflege- und Therapiekräfte für ein noch nicht definiertes Berufsfeld zu qualifizieren. Die Wissenschaft hat die Fragen nach den genauen Inhalten und der Abgrenzung akademisierter Gesundheitsberufe zu anderen, seit langem etablierten Tätigkeitsbereichen in der Patientenversorgung zu beantworten und weiterführend zukünftigen Entwicklungen aufzuzeigen. Hier erwächst der Bedarf nach einer weitergehenden Arbeitsforschung in den akademisierten, praktischen Gesundheitsberufen. Der in diesem Beitrag vorgestellte Ansatz kombiniert die Weiterqualifizierung mit der Arbeitsforschung im Berufsfeld. Ziel ist es, Weiterbildungsmodule zu konzipieren, bei denen das praktische Arbeitsfeld mit den jeweiligen Inhalten der Module systematisch in Bezug gesetzt wird. Grundlage hierzu sind didaktische Ansätze der Theorie-Praxis-Relation aus dualen Studiengängen. Zentrales Instrument ist eine reflexionsorientierte Fallstudie, die von den Teilnehmern der Weiterbildung für jedes Modul erstellt wird, in der die Teilnehmer theoriebasierte Inhalte des Moduls aufgreifen und dazu nutzen, ihr jeweiliges praktisches Arbeitsfeld mit der fachlichen Perspektive des Moduls zu reflektieren. Die Teilnehmer werden so zu Praxisforschern und die Weiterbildung gleichzeitig zu einer wissenschaftlichen Berufsfeldreflexion, aus der die Praxis Impulse zur Weiterentwicklung erhält.
Das Gesundheitswesen steht vor zahlreichen Veränderungen. Dazu zählen auch sich wandelnde Kompetenzprofile. Auf Seiten der Hochschulen stellt sich neben den fachlichen Aspekten zukünftiger Kompetenzprofile verstärkt die Frage nach einer höheren systemischen Durchlässigkeit und damit auch nach einer optimalen Vernetzung hochschulischer und außerhochschulisch erworbener Kompetenzen. Insbesondere in den Gesundheitsfachberufen nehmen non-formal und informell erworbene Kompetenzen einen hohen Stellenwert ein. Somit stellt sich die Herausforderung, wie die Ausgestaltung eines hochschulischen Zertifikatsprogrammes erfolgen kann, das zum einen eine Qualifizierung auf akademischem Niveau bietet und gleichzeitig die bestehenden non-formal bzw. informell im Berufsfeld erworbenen Kompetenzen der Lernenden erfassen, bewerten und entsprechend zertifizieren kann. Zielstellung ist es letztendlich, die Gesamtkompetenz einer Person in einem klar umgrenzten thematischen Umfeld zu erfassen, wertzuschätzen“ bzw. zu bewerten und gezielt weiter zu entwickeln, wobei außerhochschulische Kompetenzen eine wichtige Rolle spielen. Die in diesem Rahmen zertifizierten Kompetenzen stehen in einem möglichen Folgeprozess für eine entsprechende Anrechnung zur Verfügung. Vorgestellt wird ein erster Prototyp, der sich insbesondere als eine Erweiterung bestehender Denkmodelle im Bereich der Anrechnung versteht.

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.
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.

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.
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.
