Theater und Klinik! Zwei Wörter, die zunächst nicht zusammenpassen wollen. Das Forschungsprojekt „Entwicklung einer Systematik von theaterpädagogischen Arbeitsformaten“ untersuchte im ersten Halbjahr 2018, im Rahmen der „Theaterklinik Lingen“, in welchen Formaten sich gelingende theaterpädagogische Arbeit im Kosmos Krankenhaus konstituiert.
Der Beitrag beschäftigt sich mit der Wirksamkeit von Nudging, Boosting und Empowerment in der Gesundheitsvorsorge. Hierfür wurde die Einstellung von jungen, ernährungsbewussten
Studentinnen gegenüber vorgestellten Nudging-, Boostingund Empowerment-Maßnahmen zur gesünderen Ernährung untersucht.
Der vorliegende Aufsatz beschäftigt sich mit der Wirksamkeit von Nudging, Boosting und Empowerment in der Gesundheitsvorsorge. Hierfür wurde im Rahmen einer Bachelorarbeit eine Gruppendiskussion durchgeführt und die Einstellung von jungen, ernährungsbewussten Studentinnen gegenüber vorgestellten Nudging-, Boosting- und Empowerment-Maßnahmen zur gesünderen Ernährung untersucht. Die Diskussion wurde anhand einer qualitativen Inhaltsanalyse ausgewertet, und darauf aufbauend wurden theoretisch und empirisch fundierte Handlungsempfehlungen entwickelt. Die Ergebnisse der Untersuchung zeigen, dass keine der präsentierten Maßnahmen allein dazu motiviert, sich gesünder zu ernähren. Die Wirksamkeit hängt bei allen Konzepten maßgeblich von der Gestaltung der Maßnahmen, dem eigenen Aufwand und den mitgebrachten Voraussetzungen der Individuen ab. So greift der Nudge nicht mehr bei bereits bewussten Verbraucher*innen, und der Boost verzeichnet bei höherem eigenen Aufwand trotzdem keine deutlich höhere Wirksamkeit. Lediglich der Empowerment-Maßnahme wird eine langfristige Wirksamkeit zugeordnet, allerdings ist sie mit dem höchsten Aufwand verbunden. Auf Basis der Forschungserkenntnisse lässt sich schlussfolgern, dass ein Methoden-Mix aus kurzfristig und langfristig wirksamen kommunikativen Maßnahmen einen Weg darstellt, verschiedene Zielgruppen zu erreichen und zu gesünderer Ernährung zu motivieren.
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.
The ability of film stars to attract viewers is a widely accepted rationale for hiring expensive actors. However, the precise mechanisms behind this ‘drawing power’ remain unclear. By reviewing the existing literature, six possible antecedents of drawing power are identified. Artists with high acting abilities (i) increase a film’s artistic appeal, (ii) function as markers of quality and (iii) facilitate the matching process with the right audiences. Widely popular, commonly perceived as beautiful/handsome but often less talented actors, on the other hand, rather (iv) facilitate the marketing campaigns of films, (v) offer entertaining interactions with famous personalities and (vi) provide manifold opportunities for gossiping. Based on a discussion of the implications for theory and a preliminary analysis of a sample of Hollywood actors, managerial recommendations for those who have and those who depend on star drawing power are developed.
Die meisten börsennotierten Gesellschaften haben ein Risikofrüherkennungssystem, das vom Abschlussprüfer ohne den Verweis auf schwerwiegende Mängel testiert wird. Tatsächlich zeigen Studien, dass die in der Praxis implementierten Systeme häufig ungeeignet sind, um an sich erkennbare bestandsgefährdende Entwicklungen zu identifizieren. Dies liegt an methodischen Schwächen, z. B. an einer fehlenden Betrachtung der Liquiditätswirkung von Risiken, einer vernachlässigten Analyse von Extremrisiken und insb. am Fehlen einer Risikoaggregation, die auch Kombinationseffekte berücksichtigt. Bei Insolvenzen, wie hier im Beispiel von Gerry Weber, lässt sich bei Betrachtung des dokumentierten Risikomanagementsystems erkennen, dass die gesetzlichen Anforderungen nicht erfüllt wurden. Um solche „überraschenden Insolvenzen“ zu vermeiden, ist es erforderlich, bessere Verfahren zu implementieren und durch Prüfer testieren zu lassen, was bisher nicht konsequent geschieht. Der Beitrag schlägt ein einfaches aber umfassendes Prüfschema für Risikofrüherkennungssysteme vor, das sowohl intern als auch von externen Prüfern verwendet werden kann.
Over the past decade, the proliferation of entrepreneurial ventures and small firms with sustainable business models have pushed the sustainability agenda in the fashion industry. Despite prominent success stories, these companies often encounter significant operative challenges that hinder growth or even cause business failure. This paper adopts a qualitative research design and uses data gathered during 18 expert interviews with entrepreneurs and executive managers of 18 firms from 13 countries to identify and explore the dominant challenges that micro- and small-sized sustainable fashion companies struggle with. The results indicate that communicating with consumers is perceived as surprisingly difficult, especially because sustainable brands need to justify higher prices and explain the added benefits of their products. Second, resource constraints lead to operative friction and overburdening of the decision makers and their small management teams. Third, sustainable sourcing and production processes are economically difficult in an industry that continues to occupy a mass and low-cost logic. Against the background of these insights, a range of managerial recommendations are developed and contextualized in the framework of the Business Model Canvas. This novel approach makes the suggestions which are rooted in the resource-based view actionable and supports sustainable businesses to better manage their operations and achieve growth. For example, collaborative approaches with different stakeholders may mitigate constraints across all three identified problem areas.
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.
In this article, we build on Stigler and Becker’s (1977) “consumption capitaltheory” and propose a novel conceptualization of film quality for the analysisof motion picture franchises. Generally, this theorypredicts that the utilityconsumers derive from a particular goodor service increases with prior con-sumption. We test our theoretical conjectures by drawing on the population ofsequels that were running in the US between 1992 and 2011. The empiricalresults point to the explanatory power of the proposed framework. Filmexecutives may use our findings to improve the profitability of their sequelproductions. From a theoretical point of view, consumption capital theoryallows for a more refined analysis of sequel performance along differentdimensions. Moreover, it may provide a fruitful basis for the analysis of otherserial media content, including books, TV, music, and games.
The location of manufacturing is operationally and strategically important for multinational companies. The spatial dispersion of manufacturing is determined by firm-specific as well as external factors, both of which are subject to constant change. After decades of offshoring production, the paper uses interview data from UK high value manufacturing companies to explore the recent phenomenon of reshoring and the strategic and operational effects of manufacturing location. The analyses show that concentrating manufacturing in home countries enables firms to increase organizational agility and stimulate innovation. However, under certain conditions, firms also continue benefiting from the known advantages of offshoring. This underlines that there is no universal recommendation for improving competitiveness by a certain spatial configuration of manufacturing. Instead, firms need to consider their specific markets, competitive context, and capabilities when strategizing manufacturing location."
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.
How do companies decide where to locate their manufacturing? This study uses insights from manufacturing company executives collected by means of in-depth interviews with 50 manufacturers in the United Kingdom to develop an understanding of manufacturing location decision making. The findings indicate that companies derive competitive advantage from organizing manufacturing in different ways. Retaining or reshoring manufacturing to a company’s home country can enhance new product development, control of quality, product customization, delivery performance, and cost leadership. On the other hand, companies can enhance new product development, customization, and delivery performance for new markets, if production facilities are offshored to or in proximity to these locations. In addition, some companies use a hybrid approach of offshoring the production of some components or products for cost arbitrage while retaining or reshoring other components or products for advantages from value chain integration. Based on the findings of this study, a set of key manufacturing location questions are developed that should be considered by firms pondering onshore, offshore, reshore, or hybrid manufacturing location decisions.
Establishment of calcareous grassland on ex-arable fields by introducing target species is one of the most frequently used methods to restore the species assemblages of this highly endangered habitat type. The present study evaluates the long-term success of calcareous grassland restoration on former arable land in the vicinity of one of the oldest nature reserves in Bavaria, the “Garchinger Heide”. The restoration experiment combined different measures like topsoil removal, transfer of freshly cut seed-containing hay and additional sowing to the following variants in a 21-year experiment: (1) No topsoil removal, no hay transfer (control), (2) no topsoil removal with immediate hay transfer, (3) topsoil removal with immediate hay transfer and (4) topsoil removal with hay transfer 10 years after the start of restoration. Eleven Red List species which had not been transferred successfully were additionally sown after 9 to 19 years. Due to a limited availability of seeds, sowing of these species was mainly restricted to areas with topsoil removal, where better establishment was expected due to low vegetation cover. Five rare species with abundant seed production were also sown to plots without topsoil removal and hay transfer. The nature reserve served both as the donor area of the target species and as the reference to evaluate restoration success. Regarding aboveground biomass and total vegetation cover, greatest similarity to the donor site was observed on plots without topsoil removal. In contrast, the highest numbers of target species occurred on plots with topsoil removal, hay transfer and additional sowing. Similarity in species composition between restoration sites and the reference area increased over time, but species composition of restored sites did not fully reflect the reference after 21 years. One reason for the remaining dissimilarity was probably that topsoil removal favored stress tolerant species which were less common on the mature and more fine-grained soils of the nature reserve. Plots without topsoil removal still differed from the reference by their high vegetation cover and a significantly higher proportion of mesophytic grassland species. The study also showed that 19 Red List species were successfully established on the former arable fields, eight of them presumably by sowing. Nevertheless, various other rare species have not been observed yet. Results on functional traits characterizing environmental adaptation and reproduction also underlined the differences between restoration plots and the reference site. Our study presents a ʽdynamic restoration approachʼ where managers evaluated the original factorial treatments after a decade and modified them by additional treatments where development was sub-optimal. Such additional treatments may have confounded the experimental design, but from a management perspective proved to be a promising option to establish species rich grassland of high conservation value with a reasonable expenditure of time.
Conceptualising event value co-destruction and developing a future agenda for events research
(2021)
Purpose
Value co-destruction has received little attention in an event-related context. This appears surprising, given that the interactions among actors at an event may also reduce the value for other participants, stakeholders and that of the entire event or the event's service ecosystem. This paper first aims to conceptualise value co-destruction and to provide an overview of related research in an event context. Second, a future research agenda for value co-destruction processes in an event context is developed.
Design/methodology/approach
Journals of the “Scimago Journal and Country Rank” were systematically reviewed for the keywords “value co-destruction”, “value destruction” and “negative value co-creation”. A second literature review specifically aimed at the events context extended the search scope to non-Scimago journals, Google Scholar and Google Web using the same keywords. All identified articles were qualitatively analysed concerning (1) the conceptualisation of value co-destruction and (2) reasons for value co-destruction.
Findings
The review of previous research highlights a limited scope of analysis, a focus on value co-destruction as an outcome and on interactions at the meso-level. Based on these findings, a holistic definition of value co-destruction is proposed. The paper identifies two major directions for future studies on value co-destruction at events and suggests specific examples.
Originality/value
The paper contributes to a more holistic understanding of value co-creation and co-destruction in an event setting. For example, a clearer understanding of the interactions that reduce the overall value of an event may assist to better design valuable events in the future.

Wirtschaftsinformatik und Medizinische Informatik gehören zu den sogenannten Bindestrich-Informatik-Fächern, die sich mit der Anwendung der Methoden und Erkenntnisse der Informatik, aber auch mit der Weiterentwicklung solcher Methoden und Erkenntnisse für gewisse Anwendungsgebiete befassen. Auf einer Podiumsdiskussion der Jahrestagung 2018 der Deutschen Gesellschaft für Medizinische Informatik, Biometrie und Epidemiologie (GMDS) wurde für Wirtschaftsinformatik, Medizinische Informatik und Informatik analysiert wie sie zueinander stehen. Die Analyse erfolgte anhand von fünf Fragen:
1. Welche grundlegenden Ziele bestimmen die jeweilige wissenschaftliche Arbeit?
2. Wie ist der Praxisbezug ausgeprägt?
3. Inwieweit sind Besonderheiten von Medizin bzw. Ökonomie prägend für die jeweilige wissenschaftliche Arbeit?
4. Welche Rolle spielen Theoriefundierung und Evidenz?
5. Was können Wirtschaftsinformatik und Informatik von Medizinischer Informatik und Medizin lernen – und umgekehrt?
Die Analyse zeigt, dass die drei Disziplinen von einem systematischen wechselseitigen Austausch profitieren können. Das „Lernende Gesundheitssystem“ bietet Ansätze für einen entsprechenden Rahmen.
Background: For more than 30 years, there has been close cooperation between Japanese and German scientists with regard to information systems in health care. Collaboration has been formalized by an agreement between the respective scientific associations. Following this agreement, two joint workshops took place to explore the similarities and differences of electronic health record systems (EHRS) against the background of the two national healthcare systems that share many commonalities.
Objectives: To establish a framework and requirements for the quality of EHRS that may also serve as a basis for comparing different EHRS.
Methods: Donabedian's three dimensions of quality of medical care were adapted to the outcome, process, and structural quality of EHRS and their management. These quality dimensions were proposed before the first workshop of EHRS experts and enriched during the discussions.
Results: The Quality Requirements Framework of EHRS (QRF-EHRS) was defined and complemented by requirements for high quality EHRS. The framework integrates three quality dimensions (outcome, process, and structural quality), three layers of information systems (processes and data, applications, and physical tools) and three dimensions of information management (strategic, tactical, and operational information management).
Conclusions: Describing and comparing the quality of EHRS is in fact a multidimensional problem as given by the QRF-EHRS framework. This framework will be utilized to compare Japanese and German EHRS, notably those that were presented at the second workshop.
Objective: To pilot benchmark measures of health information and communication technology (ICT) availability and use to facilitate cross-country learning.
Materials and Methods: A prior Organization for Economic Cooperation and Development–led effort involving 30 countries selected and defined functionality-based measures for availability and use of electronic health records, health information exchange, personal health records, and telehealth. In this pilot, an Organization for Economic Cooperation and Development Working Group compiled results for 38 countries for a subset of measures with broad coverage using new and/or adapted country-specific or multinational surveys and other sources from 2012 to 2015. We also synthesized country learnings to inform future benchmarking.
Results: While electronic records are widely used to store and manage patient information at the point of care—all but 2 pilot countries reported use by at least half of primary care physicians; many had rates above 75%—patient information exchange across organizations/settings is less common. Large variations in the availability and use of telehealth and personal health records also exist.
Discussion: Pilot participation demonstrated interest in cross-national benchmarking. Using the most comparable measures available to date, it showed substantial diversity in health ICT availability and use in all domains. The project also identified methodological considerations (e.g., structural and health systems issues that can affect measurement) important for future comparisons.
Conclusion: While health policies and priorities differ, many nations aim to increase access, quality, and/or efficiency of care through effective ICT use. By identifying variations and describing key contextual factors, benchmarking offers the potential to facilitate cross-national learning and accelerate the progress of individual countries.
The demand for evidence-based health informatics and benchmarking of 'good' information systems in health care gives an opportunity to continue reporting on recent papers in the German journal GMS Medical Informatics, Biometry and Epidemiology (MIBE) here. The publications in focus deal with a comparison of benchmarking initiatives in German-speaking countries, use of communication standards in telemonitoring scenarios, the estimation of national cancer incidence rates and modifications of parametric tests. Furthermore papers in this issue of MIM are introduced which originally have been presented at the Annual Conference of the German Society of Medical Informatics, Biometry and Epidemiology. They deal as well with evidence and evaluation of 'good' information systems but also with data harmonization, surveillance in obstetrics, adaptive designs and parametrical testing in statistical analysis, patient registries and signal processing.
Objectives: eHealth and innovation are often regarded as synonyms - not least because eHealth technologies and applications are new to their users. This position paper challenges this view and aims at exploring the nature of eHealth innovation against the background of common definitions of innovation and facts from the biomedical and health informatics literature. A good understanding of what constitutes innovative eHealth developments allows the degree of innovation to be measured and interpreted.
Methods: To this end, relevant biomedical and health informatics literature was searched mainly in Medline and ACM digital library. This paper presents seven facts about implementing and applying new eHealth developments hereby drawing on the experience published in the literature.
Results: The facts are: 1. eHealth innovation is relative. 2. Advanced clinical practice is the yardstick. 3. Only used and usable eHealth technology can give birth to eHealth innovatio. 4. One new single eHealth function does not make a complex eHealth innovation. 5. eHealth innovation is more evolution than revolution. 6. eHealth innovation is often triggered behind the scenes; and 7. There is no eHealth innovation without sociocultural change.
Conclusions: The main conclusion of the seven facts is that eHealth innovations have many ingredients: newness, availability, advanced clinical practice with proven outcomes, use and usability, the supporting environment, other context factors and the stakeholder perspectives. Measuring eHealth innovation is thus a complex matter. To this end we propose the development of a composite score that expresses comprehensively the nature of eHealth innovation and that breaks down its complexity into the three dimensions: i) eHealth adoption, ii) partnership with advanced clinical practice, and iii) use and usability of eHealth. In order to better understand the momentum and mechanisms behind eHealth innovation the fourth dimension, iv) eHealth supporting services and means, needs to be studied. Conceptualising appropriate measurement instruments also requires eHealth innovation to be distinguished from eHealth sophistication, performance and quality, although innovation is intertwined with these concepts. The demanding effort for defining eHealth innovation and measuring it properly seem worthwhile and promise advances in creating better systems. This paper thus intends to stimulate the necessary discussion.

Innovation braucht Freiraum
(2016)
Innovationen sind positiv besetzt. Deshalb reicht es nicht aus, dass etwas „neu“ ist, es muss „innovativ“ sein. Viele verbinden das mit etwas Sensationellem, das große Aufmerksamkeit auf sich lenkt und das revolutionäre Veränderungen mit sich bringt – am besten schlagartig. Gerne werden auch alle technischen Neuerungen als Innovationen bezeichnet. Aber stimmt das denn auch?
Dienstleister oder Diktator?
(2016)
Die IT in der Rolle eines Dienstleisters zu sehen, ist an unseren Krankenhäusern leider selten Realität. Denn der IT-Diktator zieht gerne in Form überbordender IT-gestützter Dokumentation durch die Arzt- und Stationszimmer. Das sei dann dem „Diktat der DRG" geschuldet, so die Begründung. Aber muss das so sein?

Objective: The more people there are who use clinical information systems (CIS) beyond their traditional intramural confines, the more promising the benefits are, and the more daunting the risks will be. This review thus explores the areas of ethical debates prompted by CIS conceptualized as smart systems reaching out to patients and citizens. Furthermore, it investigates the ethical competencies and education needed to use these systems appropriately.
Methods: A literature review covering ethics topics in combination with clinical and health information systems, clinical decision support, health information exchange, and various mobile devices and media was performed searching the MEDLINE database for articles from 2016 to 2019 with a focus on 2018 and 2019. A second search combined these keywords with education.
Results: By far, most of the discourses were dominated by privacy, confidentiality, and informed consent issues. Intertwined with confidentiality and clear boundaries, the provider-patient relationship has gained much attention. The opacity of algorithms and the lack of explicability of the results pose a further challenge. The necessity of sociotechnical ethics education was underpinned in many studies including advocating education for providers and patients alike. However, only a few publications expanded on ethical competencies. In the publications found, empirical research designs were employed to capture the stakeholders’ attitudes, but not to evaluate specific implementations.
Conclusion: Despite the broad discourses, ethical values have not yet found their firm place in empirically rigorous health technology evaluation studies. Similarly, sociotechnical ethics competencies obviously need detailed specifications. These two gaps set the stage for further research at the junction of clinical information systems and ethics.
Der zunehmende Einsatz von Informations- und Kommunikationstechnologie im Gesundheitswesen verlangt auch von Angehörigen der Pflegeberufe Kompetenzen zur Nutzung der entsprechenden Systeme und Verfahren. Vor diesem Hintergrund haben sich die AG „Informationsverarbeitung in der Pflege“ der Deutschen Gesellschaft für Medizinische Informatik, Biometrie und Epidemiologie (GMDS), die Österreichische Gesellschaft für Pflegeinformatik (ÖGPI) und die Schweizerische Interessensgruppe Pflegeinformatik (IGPI) innerhalb des Schweizer Berufsverband der Pflegefachfrauen und Pflegefachmänner (SBK) entschlossen, gemeinsame Empfehlungen für benötigte Kernkompetenzfelder in Pflegeinformatik zu erarbeiten. Auf Basis einer iterativen multimethodischen Vorgehensweise unter Einbeziehung von einer großen Anzahl von Fachexperten aus Deutschland, Österreich und der Schweiz (D-A-CH) wurden 24 notwendige Felder von Kernkompetenzen definiert und deren Relevanz für fünf typische Berufsfelder in der Pflege bewertet. Damit liegt erstmalig eine wissenschaftlich fundierte Empfehlung für zu vermittelnde Kernkompetenzfelder in der Pflegeinformatik für verschiedene pflegerische Berufsfelder vor. Sie richtet sich an alle Personen mit Verantwortung für die Planung von Studium, Lehre, Aus- und Weiterbildung in der Pflege.
Benchmarking, sprich die Vergleichsanalyse von Prozessen mit festgelegtem Bezugswert, findet zunehmend Einzug in die Welt der Gesundheits-IT. Dabei spielen jedoch viele Faktoren zusammen, die einen einfachen Vergleich von IT-Kosten bei Weitem übersteigen. Eine Forschungsgruppe der Hochschule Osnabrück hat mit dem IT-Benchmark Gesundheitswesen ein Analysetool vorgelegt, das auch einen Länder- vergleich ermöglicht.
Background: IT adoption is a process that is influenced by different external and internal factors. This study aimed
1. to identify similarities and differences in the prevalence of medical and nursing IT systems in Austrian and German hospitals, and
2. to match these findings with characteristics of the two countries, in particular their healthcare system, and with features of the hospitals.
Methods: In 2007, all acute care hospitals in both countries received questionnaires with identical questions. 12.4% in Germany and 34.6% in Austria responded.
Results: The surveys revealed a consistent higher usage of nearly all clinical IT systems, especially nursing systems, but also PACS and electronic archiving systems, in Austrian than in German hospitals. These findings correspond with a significantly wider use of standardised nursing terminologies and a higher number of PC workstations on the wards (average 2.1 PCs in Germany, 3.2 PCs in Austria). Despite these differences, Austrian and German hospitals both reported a similar IT budget of 2.6% in Austria and 2.0% in Germany (median).
Conclusions: Despite the many similarities of the Austrian and German healthcare system there are distinct differences which may have led to a wider use of IT systems in Austrian hospitals. In nursing, the specific legal requirement to document nursing diagnoses in Austria may have stimulated the use of standardised terminologies for nursing diagnoses and the implementation of electronic nursing documentation systems. Other factors which correspond with the wider use of clinical IT systems in Austria are: good infrastructure of medical-technical devices, rigorous organisational changes which had led to leaner processes and to a lower length of stay, and finally a more IT friendly climate. As country size is the most pronounced difference between Germany and Austria it could be that smaller countries, such as Austria, are more ready to translate innovation into practice.
Hochschule und Universität Osnabrück haben mit regionalen Partnern (Stadt, Landkreis, Bistum, evangelisch-lutherischem Kirchenkreis, Kompetenzzentrum Gesundheitswirtschaft) die Grundsatzvereinbarung unterzeichnet, in Osnabrück einen Gesundheitscampus zu etablieren. Das Ziel ist, einen Ort zu schaffen, an dem Wissenschaft, Unternehmen der Gesundheitsversorgung, Träger von Gesundheitseinrichtungen und Politik zusammenkommen, um innovative Versorgungskonzepte für die Region zu erproben. „ROSE – das Lernende Gesundheitssystem in der Region Osnabrück-Emsland“ ist ein Großprojekt im Rahmen des Gesundheitscampus Osnabrück, das von dem Niedersächsischen Ministerium für Wissenschaft und Kultur (MWK) über 5 Jahre gefördert wird. Dabei wird das Prinzip des Lernens durch Feedback angewendet. Das bedeutet, dass durch Forschung in und mit der Praxis Evidenz im Sinne von practice-based evidence erzeugt wird, d.h. Evidenz für eine bessere Versorgungspraxis unter Berücksichtigung städtischer und ländlicher Strukturen. Dies hat zur Konsequenz, dass der Transferprozess zwischen Hochschule und Versorgungspraxis nicht am Ende sondern bereits am Anfang steht. Mit dem Ansatz einer wiederkehrenden Abfolge von Forschungsfragen und Analysen von Daten aus der Versorgungspraxis rekurriert ROSE auf das Prinzip des „Learning Health Care System“ (IOM, 2007). Im Rahmen von ROSE stimmen sich Hochschule und Universität Osnabrück ab, um die Ziele des Gesundheitscampus zu erreichen. Die geplante Umsetzung wird anhand eines Modells mit fünf Maßnahmen vorgestellt. Diese bauen auf der Vielfalt von bereits bestehenden Gesundheitsstudiengängen in Osnabrück auf und bringen Forschung, Nachwuchsförderung und Translation von Forschungsergebnissen zusammen.
The TIGER Initiative
(2016)
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.
Background: Clinical information logistics is the backbone of care workflows inside and outside of hospitals. Due to the great potential of health IT to support clinical processes its contribution needs to be regularly monitored and governed. IT benchmarks are a well-known instrument to optimise the availability and use of IT by guiding the decision making process. The aim of this study was to translate IT benchmarking results that were grounded on a hierarchical workflow scoring system into an appropriate visualisation concept.
Methods: To this end, a three-dimensional multi-level model was developed, which allowed the decomposition of the highly aggregated workflow composite score into score views for the individual clinical workflows concerned and for the descriptors of these workflows. Furthermore this multi-level model helped to break down the score views into single and multiple indicator views.
Results: The results could be visualised per hospital in comparison to the results of organisations of similar size and ownership (peer reference groups) and in comparison to different types of innovation adopters. The multi-level model was implemented in a benchmark of 199 hospitals and evaluated by the chief information officers. The evaluation resulted in high ratings for the comprehensibility of the different types of views of the scores and indicators.
Conclusions: The implementation of the multi-level model in a large benchmark of hospitals proved to be feasible and useful in terms of the overall structure and the different indicator views. There seems to be a preference for less complex and familiar views.
Menschen erzählen sich Geschichten, um sich etwas vorzustellen, sich eine Vision auszumalen und daraus etwas Neues, Besseres zu erbauen. Im Rahmen des Aufsatzes werden Geschichten über eine nachhaltige bzw. zukunftsfähige Lebensweise betrachtet. Diese realen (faktualen) Geschichten erzählen von Menschen und Organisationen, denen der Wandel zu einer nachhaltigen Lebens- und Wirtschaftsweise in ihrem Handlungsfeld gelingt und die andere zum Wandel ermutigen (als sogenannte Change Agents). Sie etablieren innerhalb der bestehenden Rahmenbedingungen neue Werte und Handlungsweisen und schaffen damit Reallabore, in denen „das Neue“ ausprobiert, angeschaut und weitererzählt werden kann. Der Aufsatz nimmt erzähltheoretische Grundlagen zur Hilfe und zeigt anhand eines Fallbeispiels, wie Geschichten das zunächst abstrakte Konzept Nachhaltigkeit konkret und anschaulich kommunizieren können. Die entsprechende narrativ-analytische Perspektive öffnet den Blick für die Werte und Prinzipien, die in Form von Narrativen (Erzählstrukturen) in einzelnen Geschichten und auch in Diskursen vermittelt werden. Für professionelle Kommunikatoren kann diese Perspektive ein Methodenansatz sein, um Veränderungsprozesse besser zu verstehen und das eigene Storytelling auf eine fundierte Basis zu heben.
Background
Diabetes mellitus is a major global health issue with a growing prevalence. In this context, the number of diabetic complications is also on the rise, such as diabetic foot ulcers (DFU), which are closely linked to the risk of lower extremity amputation (LEA). Statistical prediction tools may support clinicians to initiate early tertiary LEA prevention for DFU patients. Thus, we designed Bayesian prediction models, as they produce transparent decision rules, quantify uncertainty intuitively and acknowledge prior available scientific knowledge.
Method
A logistic regression using observational collected according to the standardised PEDIS classification was utilised to compute the six-month amputation risk of DFU patients for two types of LEA: 1.) any-amputation and 2.) major-amputation. Being able to incorporate information which is available before the analysis, the Bayesian models were fitted following a twofold strategy. First, the designed prediction models waive the available information and, second, we incorporated the a priori available scientific knowledge into our models. Then, we evaluated each model with respect to the effect of the predictors and validity of the models. Next, we compared the performance of both models with respect to the incorporation of prior knowledge.
Results
This study included 237 patients. The mean age was 65.9 (SD 12.3), and 83.5% were male. Concerning the outcome, 31.6% underwent any- and 12.2% underwent a major-amputation procedure. The risk factors of perfusion, ulcer extent and depth revealed an impact on the outcomes, whereas the infection status and sensation did not. The major-amputation model using prior information outperformed the uninformed counterpart (AUC 0.765 vs AUC 0.790, Cohen’s d 2.21). In contrast, the models predicting any-amputation performed similarly (0.793 vs 0.790, Cohen’s d 0.22).
Conclusions
Both of the Bayesian amputation risk models showed acceptable prognostic values, and the major-amputation model benefitted from incorporating a priori information from a previous study. Thus, PEDIS serves as a valid foundation for a clinical decision support tool for the prediction of the amputation risk in DFU patients. Furthermore, we demonstrated the use of the available prior scientific information within a Bayesian framework to establish chains of knowledge.
Multinational health IT benchmarks foster cross-country learning and have been employed at various levels, e.g. OECD and Nordic countries. A bi-national benchmark study conducted in 2007 revealed a significantly higher adoption of health IT in Austria compared to Germany, two countries with comparable healthcare systems. We now investigated whether these differences still persisted. We further studied whether these differences were associated with hospital intrinsic factors, i.e. the innovative power of the organisation and hospital demographics. We thus performed a survey to measure the “perceived IT availability” and the “innovative power of the hospital” of 464 German and 70 Austrian hospitals. The survey was based on a questionnaire with 52 items and was given to the directors of nursing in 2013/2014. Our findings confirmed a significantly greater IT availability in Austria than in Germany. This was visible in the aggregated IT adoption composite score “IT function” as well as in the IT adoption for the individual functions “nursing documentation” (OR = 5.98), “intensive care unit (ICU) documentation” (OR = 2.49), “medication administration documentation” (OR = 2.48), “electronic archive” (OR = 2.27) and “medication” (OR = 2.16). “Innovative power” was the strongest factor to explain the variance of the composite score “IT function”. It was effective in hospitals of both countries but significantly more effective in Austria than in Germany. “Hospital size” and “hospital system affiliation” were also significantly associated with the composite score “IT function”, but they did not differ between the countries. These findings can be partly associated with the national characteristics. Indicators point to a more favourable financial situation in Austrian hospitals; we thus argue that Austrian hospitals may possess a larger degree of financial freedom to be innovative and to act accordingly. This study is the first to empirically demonstrate the effect of “innovative power” in hospitals on health IT adoption in a bi-national health IT benchmark. We recommend directly including the financial situation into future regression models. On a political level, measures to stimulate the “innovative power” of hospitals should be considered to increase the digitalisation of healthcare.
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.
Background:
Chronic health conditions are on the rise and are putting high economic pressure on health systems, as they require well-coordinated prevention and treatment. Among chronic conditions, chronic wounds such as cardiovascular leg ulcers have a high prevalence. Their treatment is highly interdisciplinary and regularly spans multiple care settings and organizations; this places particularly high demands on interoperable information exchange that can be achieved using international semantic standards, such as Systematized Nomenclature of Medicine-Clinical Terms (SNOMED CT).
Objective:
This study aims to investigate the expressiveness of SNOMED CT in the domain of wound care, and thereby its clinical usefulness and the potential need for extensions.
Methods:
A clinically consented and profession-independent wound care item set, the German National Consensus for the Documentation of Leg Wounds (NKDUC), was mapped onto the precoordinated concepts of the international reference terminology SNOMED CT. Before the mapping took place, the NKDUC was transformed into an information model that served to systematically identify relevant items. The mapping process was carried out in accordance with the ISO/TR 12300 formalism. As a result, the reliability, equivalence, and coverage rate were determined for all NKDUC items and sections.
Results:
The developed information model revealed 268 items to be mapped. Conducted by 3 health care professionals, the mapping resulted in moderate reliability (κ=0.512). Regarding the two best equivalence categories (symmetrical equivalence of meaning), the coverage rate of SNOMED CT was 67.2% (180/268) overall and 64.3% (108/168) specifically for wounds. The sections general medical condition (55/66, 83%), wound assessment (18/24, 75%), and wound status (37/57, 65%), showed higher coverage rates compared with the sections therapy (45/73, 62%), wound diagnostics (8/14, 57%), and patient demographics (17/34, 50%).
Conclusions:
The results yielded acceptable reliability values for the mapping procedure. The overall coverage rate shows that two-thirds of the items could be mapped symmetrically, which is a substantial portion of the source item set. Some wound care sections, such as general medical conditions and wound assessment, were covered better than other sections (wound status, diagnostics, and therapy). These deficiencies can be mitigated either by postcoordination or by the inclusion of new concepts in SNOMED CT. This study contributes to pushing interoperability in the domain of wound care, thereby responding to the high demand for information exchange in this field. Overall, this study adds another puzzle piece to the general knowledge about SNOMED CT in terms of its clinical usefulness and its need for further extensions.
Der Kunde als Dienstleister: Akzeptanz und Gebrauchstauglichkeit von Smart Glasses im Self-Service
(2017)
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.
Der vorliegende Beitrag fokussiert die Bedeutung Nachhaltigkeitsorientierter Unternehmenskultur für den Einsatz von künstlicher Intelligenz im Marketing. Spezifischer skizzieren wir die Einflussmöglichkeiten auf den Einsatz nachhaltiger künstlicher Intelligenz zur Förderung des Sustainable Development Goals 12 (Nachhaltige/r Produktion & Konsum). In einem diskursiven Ansatz führt dieser Beitrag Erkenntnisse aus der Literatur zur nachhaltigkeitsorientierten Unternehmenskultur, nachhaltigen künstlicher Intelligenz und dem Nachhaltigkeitsmarketing zusammen und bildet diese mithilfe des St. Galler Managementmodells ab.
Information systems (IS) play a central role in promoting corporate sustainability and pro-environmental behavior. This study explores the use of mobile apps for fostering sustainability-oriented corporate culture. It accentuates issues relating to sustainability-oriented corporate culture (RQ1), app meta-requirements as a strategic approach to addressing these issues (RQ2), as well as design and implementation principles (RQ3). Referring to the literature on sustainability apps, gamification, and nudging, our qualitative research design combines an analysis of four corporate apps intending to promote sustainable behavior and expert interviews (Grounded Theory). The proposed framework supports the planning, realization, and monitoring of this targeted app use. Single cultural dimensions inform seven issues in culture development. Five meta-requirements address this multi-dimensionality, challenges provided by new digital working environments, and principles of Green IT. Four design principles support, extend, and integrate current knowledge on app features, nudging, and gamification. Five variables determine the app intervention and maturity level. We conclude that this targeted app use should intend to foster the sustainability orientation within all dimensions of corporate culture instead of being limited to promoting sustainable behavior.
Purpose
The purpose of this paper is to distinguish different types of sustainable digital entrepreneurs (SDEs) and explore their approaches toward enhancing organizational resilience.
Design/methodology/approach
Investigation of entrepreneur characteristics using Grounded Theory methodology; 12 semi-structured telephone interviews with (owner-)managers of digital-resilient small and medium-sized enterprises (SMEs) and start-ups in Germany; adaptation of a sustainability-digitalization-matrix for initial clustering; investigation of reoccurring patterns (within and between clusters) through variable-oriented content analysis; application of the capability-based conceptualization of organizational resilience for synthesis and extension.
Findings
First, the authors present a new typology of SDEs, including descriptions of the four main types (Process-Oriented System Thinker, Unconventional Strategist, Dynamic Visionary and Success-Oriented Opportunist). Second, the authors propose a conceptual framework with six success factors of organizational resilience. The framework accentuates the influence of SDEs on organizational culture and the macro-environment.
Practical implications
Digital sustainability and resilience are emerging management principles. The insights gained will allow (future) entrepreneurs to perform a self-assessment and replicate approaches toward enhancing SME resilience; for example, governing the co-creation of an organizational culture with a strong integrative view on sustainability and digitalization.
Originality/value
SMEs are characterized by high vulnerability and a reactive response to the disruptions caused by sustainability crises and digitalization. Blending sustainable and digital entrepreneurship at a micro-level, the authors identified the success factors underpinning organizational resilience that are associated with the characteristics of four types of SDEs.
In the race against climate change, small and medium-sized enterprises (SMEs) play a fundamental role. To clarify the contribution of corporate culture to SMEs' emission reduction, three perspectives can be useful: corporate culture as driver and barrier, current and planned corporate culture development actions, and the corporate culture profile as an outcome. As the first application of the extended Belief-Action-Outcome framework, this single case study exemplifies the role of corporate culture in an SME from the steel construction and manufacturing sector in Germany. The investigated SME has achieved emission reduction while increasing its revenue and is an early adopter of sustainable and digital development. The rich insights from an employee survey, semi-structured interviews, observation, and document analysis allowed us to outline an informed approach toward corporate culture development that emphasizes vision development of the desired corporate culture and the role of information systems for promoting emission reduction.
Social networking technologies such as social media, crowd concepts, or gamification represent key resources for the integration of customers, value network partners, and the community into sustainable business models. However, there is a lack of understanding of how sustainable enterprises apply such technologies. To close this gap, we propose a taxonomy of design options for social networking technologies in sustainable business models. Our taxonomy comprises eight dimensions that deal with relevant questions of the design of social networking technologies. When creating our taxonomy, we built on existing literature and use cases and involved experienced practitioners in the field of sustainable business models for the validation of our taxonomy. In this way, our study contributes to knowledge on the use of social networking technologies in sustainable business models and how such technologies influence the boundaries of sustainable business models. Likewise, we provide practical insights into the use of social networking technologies in sustainable business models.
A recently published study of high temperature nitridation of iron chromium aluminum alloys (FeCrAl) at 900°C in N2–H2 has redundantly shown the formation of locally confined corrosion pockets reaching several microns into the alloy. These nitrided pockets form underneath chromia islands laterally surrounded by the otherwise protective alumina scale. Chromia renders a nitrogen‐permeable defect under the given conditions and the presence of aluminum in the alloy. In light of these findings on FeCrAl, a focused ion beam–scanning electron microscope tomography study has been undertaken on an equally nitrided FeNiCrAl sample to characterize its nitridation corrosion features chemically and morphologically. The alloy is strengthened by a high number of chromium carbide precipitates, which are also preferential chromia formation sites. Besides the confirmation of the complete encapsulation of the corrosion pocket from the alloy by a closed and dense aluminum nitride rim, very large voids have been found in the said pockets. Furthermore, metallic particles comprising nickel and iron are deposited on top of the outer oxide scale above such void regions.
The political geography of central government debt has hardly been investigated. We propose a method for calculating implicit interregional transfers stemming from central government debt.
We apply this method to Belgium over the 1970-2016 period. The share of poorer Francophone Belgium in debt-financed central government spending was persistently larger than its share in central government revenue used to pay the resulting interest bills. The opposite holds for richer Flanders. Also, a primary deficit in one particular year leads to an interest bill in each of the following years as long as debt caused by that primary deficit is not repaid. All the above caused debt-related transfers from Flanders to Francophone Belgium of over 7% of Flemish GDP during many years.
Interregional interest transfers may also be large in the many other democracies suffering from both high central government debt and considerable geographic income disparities.
The size of these transfers may in turn explain the size and persistence of central government deficits. This is also because poorer, less densely populated regions such as Francophone Belgium tend to be overrepresented within central governments. This strengthens their ability to cause deficits.
We recommend more fiscal decentralisation or at least smaller central government deficits.
Bitte nicht stupsen?! Wahrnehmung und Akzeptanz verschiedener Nudges durch deutsche Staatsbürger
(2017)
Mithilfe von Nudges können Menschen in Entscheidungssituationen in eine bestimmte Richtung gesteuert werden, ohne ihre Wahlfreiheit zu verlieren. In den letzten Jahren erfolgte eine intensive Auseinandersetzung mit dem Thema, sowohl in der Wissenschaft als auch in der Öffentlichkeit. Nudges werden von vielen Experten sehr kritisch betrachtet. Doch wie beurteilen Bürger diese Art der Steuerung? Der Aufsatz beschäftigt sich mit der Wahrnehmung und Akzeptanz von Nudges durch deutsche Staatsbürger. In einer qualitativen Studie wurden drei Gruppendiskussionen durchgeführt, in denen sieben verschiedene Nudges vorgestellt wurden, um zu ergründen, wie einzelne Maßnahmen bewertet werden, inwieweit die Bewertung in Abhängigkeit von Themen und Maßnahmen variiert und welche Einflussfaktoren auf die Akzeptanz derartiger Maßnahmen feststellbar sind. Es konnten eine Reihe von Einflussfaktoren identifiziert werden, die eine Basis für weitere Untersuchungen darstellen und zudem Hinweise darauf geben, was bei der Konzeption von Nudges beachtet werden sollte, um die Zustimmung und Akzeptanz der Bürger zu sichern.
The influence of moderate electric fields (MEF) on thermally induced gelation and network structures of patatin enriched potato protein (PPI) was investigated. PPI solutions with 9 wt% protein (pH 7) and 25 mM NaCl were heated from 25 to 65 °C via OH (3–24 V/cm) or conventional heating (COV) at various come-up (240 s and 1200 s) and holding times (30 s and 600 s). Self-standing gels were produced but less proteins denatured when heated via OH. Further, SDS-PAGE and GPC measurements revealed more native patatin remaining after OH treatment. Scanning electron microscopy showed OH gels to have more gap-like structures and frayed areas than COV treated gels which resulted in lower water holding capacity. On molecular scale, less hydrophobic interactions were measured within the protein network and FTIR trials showed the MEF to affect beta-sheet structures. OH gels further showed lower rigidity and higher flexibility, thus, gelling functionality was affected via OH.
Ohmic heating (OH) is an alternative sustainable heating technology that has demonstrated its potential to modify protein structures and aggregates. Furthermore, certain protein aggregates, namely amyloid fibrils (AF), are associated with an enhanced protein functionality, such as gelation. This study evaluates how Ohmic heating (OH) influences the formation of AF structures from ovalbumin source under two electric field strength levels, 8.5 to 10.5 and 24.0–31.0 V/cm, respectively. Hence, AF aggregate formation was assessed over holding times ranging from 30 to 1200 sunder various environmental conditions (3.45 and 67.95 mM NaCl, 80, 85 and 90 °C, pH = 7). AF were formed under all conditions. SDS-PAGE revealed that OH had a higher tendency to preserve native ovalbumin molecules. Furthermore, Congo Red and Thioflavin T stainings indicated that OH reduces the amount of AF structures. This finding was supported by FTIR measurements, which showed OH samples to contain lower amounts of beta-sheets. Field flow fractioning revealed smaller-sized aggregates or aggregate clusters occurred after OH treatment. In contrast, prolonged holding time or higher treatment temperatures increased ThT fluorescence, beta-sheet structures and aggregate as well as cluster sizes. Ionic strength was found to dominate the effects of electric field strength under different environmental conditions.
The influence of oil content and droplet size of oil-in-water emulsions on the heat development in an ohmic heating system was investigated. The setup was run with constant power or voltage. Emulsions consisted of sunflower oil (10–50 wt%), aqua dest. (90–50 wt%) and whey protein isolate (1.25/ 2.5/ 3.75/ 5.0 and 6.25 wt%) Two different droplet size distributions were produced, large (d0.5 ≈ 2.0 μm) and small (d0.5 ≈ 0.3 μm), for each oil mass fraction. The emulsions were ohmically heated from 10 to 80 °C at a constant power of 3.0 kW and constant voltage of 15 V/cm. The electrical conductivity decreased with an increasing oil content, resulting in longer or shorter heating time for constant voltage or constant power input, respectively. The droplet size only affected the heating process at the highest oil content.
Industrial relevance
Emulsions occur in a wide range of food products (e.g. sauces, dressings, desserts) and have properties giving structure to the food system. Ohmic heating is an emerging thermal process with improved (e.g. faster or less energy required) heating characteristics. The influence of physical changes due to different droplet sizes are of interest because these might also affect the heating characteristic. In addition, the direct comparison of two different process regulations (constant power and constant voltage) indicate which set up is expedient to a successful heating process. This study aims to identify the influence of emulsion-induced structural changes and process changes on the heating rates, which is of interest for the food industry and the related machine building industry.
The present study investigates properties of heat-induced, self-standing gels of globular proteins. Native egg white protein (EWP) with 9,8 wt% protein and 0,395 wt% NaCl content was adjusted to pH = 7,0 and heated from 25 to 85 °C via Ohmic heating (OH) and conventional heating (COV) with respective come-up times (CUT, 240 and 1200 s) and holding times (HOLD, 30 and 900 s). Gels heated under OH showed lower denaturation levels and less water holding capacity. When HOLD was short, the firmness of OH gels exceeded COV gel firmness but deceeded at long HOLD. Similarly, at short HOLD OH samples presented higher hydrophobic interactions whereas at long HOLD COV gels showed more hydrophobic interactions. This correlated with changes of intermolecular beta-sheet structures which increased with HOLD at COV but decreased or remained unchanged during OH. Furthermore, as an SDS-PAGE revealed the main EWP, ovalbumin, did not fully denature when heated via OH, this lead to the assumption that the oscillatory electric field partially interferes the complete denaturation and development of intermolecular beta-sheet structures and hydrophobic interactions during thermal gelation of this protein. Scanning electron microscopy also showed deviances in network structures between OH and COV as COV gels exhibited a denser and OH gels a more open and porous network structure.
The current study presents a new class of functional derivatives (1–3) consisting of a dicationic viologen (4,4’-bipyridinium unit) (V21) capped by nucleobases thymine (NB1), adenine (NB2), thymine/adenine (NB1, NB2), and ion-paired with amphiphilic anion 3,4,5-tris(dodecyloxy)benzene sulfonate (DOBS-). The target of our work focuses on the design and synthesis of molecular building blocks in which three different functionalities are combined: chromophore (V21 unit), molecular recognition (NB unit), and thermotropic liquid crystal (DOBS unit). The resulted materials exhibit liquid crystalline properties at ambient temperature with significant particularities-induced by nucleobases in the mesogen structure. Structure–properties relationship study focuses on providing knowledge about (1) how the thermotropic, redox properties, thermochromism, or ionic conductive properties are influenced by the presence of purinic or pyrimidinic nucleobases, and (2) how effective is their ability to selfassembly by hydrogen bonding in nonpolar solvents. The presence of nucleobases has been proved to have a substantial impact on electron transfer rate during the reduction of viologen moieties by intermolecular aggregation. Ionic conductivity and thermochromic properties of derivatives 1–3 were investigated and compared to a non-containing nucleobase analog methyl viologen with 3,4,5 tris(dodecyloxy)benzene sulfonate anion (MV) as reference.
The objective of this review is a global assessment of the economics of second‐generation biorefineries, with a focus on the use of food waste and agricultural residues for chemical production by applying biotechnological processes. Analyses are conducted on feedstock and product distribution, applied economic models, and profitability figures for the period 2013–2018. In a study of 163 articles on different biorefinery systems, the production of chemicals is identified as the second major product class, after bioenergy. Bagasse and straw are frequently analyzed second‐generation feedstocks. Based on the evaluation of 22 articles, second‐generation biorefineries producing chemicals by applying biotechnological processes proves to be economically feasible. On average, both the internal rate of return (IRR) and the return on investment (ROI) are 20% and the payback period (PP) is 6 years. The cost share of feedstock in biorefineries is between 0–50%. The price of the end product and the fermentation yields have the most impact on profitability. The processing of food waste that has industrial and municipal origins appears more economical than the processing of agricultural residues. Scientists, policy makers and entrepreneurs with an appropriate risk tolerance are advised to pay particular attention to municipal food waste and the potential economic production of carboxylic acids. For various economic issues related to biorefineries, dynamic‐deterministic models are recommended, which can be extended by a stochastic model. This review provides an initial overview of the economic feasibility of second‐generation biorefineries. Further techno‐economic analyses are required to produce statistically significant statements on key profitability figures. © 2020 The Authors.

Background and Objectives
Despite the long-standing consensus on the importance of tumor size, tumor number and carcinoembryonic antigen (CEA) levels as predictors of long-term outcomes among patients with colorectal liver metastases (CRLM), optimal prognostic cut-offs for these variables have not been established.
Methods
Patients who underwent curative-intent resection of CRLM and had available data on at least one of the three variables of interest above were selected from a multi-institutional dataset of patients with known KRAS mutational status. The resulting cohort was randomly split into training and testing datasets and recursive partitioning analysis was employed to determine optimal cut-offs. The concordance probability estimates (CPEs) for these optimal cut offs were calculated and compared to CPEs for the most widely used cut-offs in the surgical literature.
Results
A total of 1643 patients who met eligibility criteria were identified. Following recursive partitioning analysis in the training dataset, the following cut-offs were identified: 2.95 cm for tumor size, 1.5 for tumor number and 6.15 ng/ml for CEA levels. In the entire dataset, the calculated CPEs for the new tumor size (0.52), tumor number (0.56) and CEA (0.53) cut offs exceeded CPEs for other commonly employed cut-offs.
Conclusion
The current study was able to identify optimal cut-offs for the three most commonly employed prognostic factors in CRLM. While the per variable gains in discriminatory power are modest, these novel cut-offs may help produce appreciable increases in prognostic performance when combined in the context of future risk scores.
Woran Manager scheitern
(2021)
Das Scheitern von Managern rückt vor allem dann in den Fokus der Öffentlichkeit, wenn es um millionenschwere Fehlentscheidungen geht oder prominente Personen betroffen sind. Derartige Fälle sind jedoch nur die Spitze des Eisbergs. Die Gründe für das Scheitern sind ebenso vielfältig wie die Maßnahmen dagegen.
Das Unternehmen "100 Worte Sprachanalyse" hat 2021 den "HR Startup Award" erhalten, der federführend vom Bundesverband der Personalmanager (BPM) verliehen wird. Überzeugt hat 100 Worte "mit dem Versprechen, den unbewussten Gender-Bias in Stellenanzeigen zu reduzieren und unterschiedliche Grundmotive von Bewerbergruppen zu erfassen", so die Initiatoren. Doch es bestehen berechtigte Zweifel daran, dass die Software dieses Versprechen einlösen kann.
Managementversagen (Derailment) findet seine Ursachen u. a. in den Merkmalen der betroffenen Führungskräfte. Die bisherige Forschung identifiziert zahlreiche Variablen, die sich auf Management-Skills, Führungsstil, soziale Kompetenzen, Persönlichkeit sowie subklinische Persönlichkeitsmerkmale beziehen. Neben einer Darstellung dieser Merkmale und der Diskussion bestehender Forschungsdefizite wird der Frage nachgegangen, welche Möglichkeiten die Personaldiagnostik zur Reduzierung des Problems bietet.
Bewerbungsunterlagen gehören zu den klassischen Instrumenten der Personalauswahl. Über die Validität ihrer einzelnen Elemente ist nur wenig bekannt. Der vorliegende Artikel liefert einen Überblick über vier aktuelle Studien, die sich mit der Validität verschiedener biographischer Daten beschäftigen: sportliche Aktivitäten, Führungserfahrung, Lücken im Lebenslauf und soziales Engagement. Während sich bei den ersten beiden Kriterien keine Hinweise auf eine nennenswerte Validität finden ließen, zeigte sich bei den beiden
verbleibenden Kriterien eine geringfügige Validität. Die Ergebnisse unterstreichen insgesamt die Erkenntnis, dass es sich bei der Sichtung der Bewerbungsunterlagen um eine Methode handelt, die in nur sehr eingeschränktem Maße verlässliche Informationen über einen Bewerber liefert. Es wird dafür plädiert, verstärkt Online-Testverfahren zur Vorauswahl der Bewerber einzusetzen.
In der Psychologie stehen Ehrgeiz, Ambition und Motivation als Synonyme
für den inneren Antrieb. Dieser ist Grundlage für die Leistungen und Anstrengungen, die aufgebracht werden, um Anerkennung – vor allem im Beruf – zu erhalten. Welche Motive dahinter stehen und welche Rolle sie spielen, um einen Bewerber und dessen soziale Kompetenzen einschätzen zu können, beschreibt für uns der Wirtschaftspsychologe, Prof. Dr. Uwe Peter Kanning.
