Studien indizieren, dass die Generation Z, die sogenannten „Digital Natives“, einen leichten Zugang zu Informations- und Kommunikationstechnologien (IKT) hat. Zugleich attribuieren sich die Individuen dieser Generation auch selbst eine hohe IKT-Affinität. Diese Kombination legt gewisse Lehrmethoden (wie Selbststudium oder Projektarbeit) im Rahmen der Hochschullehre auch für ERP-Systeme nahe. An diesem Punkt setzt dieser Beitrag an und zeigt in einem Experiment anhand von zwei SAP-Lernumgebungen mit vier Studierendengruppen, dass die unreflektierte und implizite Annahme der hohen IKT-Affinität recht trügerisch und kontraproduktiv für die Lehre ist. Von Studierenden selbst gewählte Lernmethoden haben dabei das Nachsehen. Damit einhergehend führen mehrdimensionale Lehrmethoden zu messbar höheren Lernerfolgen. Theoretisch begleitet wird diese Arbeit vom Technology Acceptance Model (TAM).

Wie wirksam ist Mentoring?
(2022)
15 Minuten Wirtschaftspsychologie
Viele Arbeitgeber setzen Mentoring ein, um insbesondere neuen Mitarbeiterinnen und Mitarbeitern zu Helfen, damit sie ihren Weg im Unternehmen erfolgreich gehen. Die Forschung zeigt, dass Mentoring eine sinnvolle Methode ist, die durch gezielte Maßnahmen auch nennenswerte Effekte nach sich zieht.
Kolumne Wirtschaftspsychologie
Mit psychologischen Fakten und einer großen Portion Sarkasmus klärt Professor Uwe P. Kanning in seiner Kolumne über Mythen und Missstände im Bereich der Führung, Personalauswahl und Personalentwicklung auf. Heute seziert er die Methoden der allzu erfahrenen Interviewenden im Einstellungsgespräch und zeigt auf, welchen Schaden sie anrichten können.
The Corona pandemic confronted societies with several unexpected constraints that had the effect of making certain goods much scarcer than before. Withdrawal from Russian oil and gas supplies has a similar effect. Carbon abatement can also be seen as a deliberate choice to make certain goods scarc-er than they actually are. These parallels suggests that it may be worthwhile to take a close look at societies’ responses to all three challenges. This paper makes an attempt to synthetize empirical and theoretical insights regarding these scarcity shocks from a well-being perspective, i.e. replacing the prevalent welfare economic focus on production and consumption with a focus on sustainable well-being.
Taking the case of Germany, it will be argued that the observed responses to all three challenges reflect a focus on maintaining incomes and production and that therefore these responses risk being detrimental to sustainable wellbeing and even to economic stability. This is particularly relevant if carbon abatement requires not only transient material sacrifices but lasting and significant reduc-tions of consumption.
It will be argued that the impact of these new scarcities will be much less problematic in a society that acknowledges the priority of sustainable wellbeing over production and consumption measures. Such a society would still need to incur material sacrifices, but these need not translate into a loss of wellbeing if economic conditions and social norms adapt. This will also be more sustainable not only in terms of ecological impact, but also in terms of debt, inflation and inequality.
Im Zuge bildungspolitischer Änderungen haben Kindertagesstätten in den letzten Jahrzehnten einen Bedeutungswandel erfahren. Sie sind verstärkt zu Orten von Wissensproduktionen erklärt worden, an die hohe Erwartungen im Hinblick auf die Kompensation von ‚ungünstigen‘ Ausgangsvoraussetzungen von Kindern und ihren Übergang in die Grundschule gestellt werden. Dabei erfährt der Diskurs über ‚Sprachdefizite von Migrantenkindern‘ im Austausch zwischen frühpädagogischen Fachkräften und Lehrkräften eine besondere Gewichtung. Dies verdeutlichen Aussagen von Kindertagesstätten-Leitungskräften, die im Rahmen der Studie „Von Sprachdefiziten und anderen Mythen. Eine Studie zum Nicht-Verbleib von Elementarpädagoginnen und -pädagogen mit Migrationshintergrund“ befragt worden sind.
Der Beitrag setzt sich auf der Grundlage dieser Studie kritisch mit institutionell und strukturell gegebenen diskriminierenden und rassialisierenden Mechanismen und Praxen im Umgang mit Mehrsprachigkeit in der Elementarpädagogik auseinander. Ein Fokus wird auf die Analyse von Differenzkonstruktionen und Interaktionsprozessen zwischen pädagogischen Fachkräften mit und ohne ‚Migrationshintergrund‘ gelegt, die im Rahmen von quantitativen und qualitativen Ansätzen untersucht worden sind. Aus den Analysen lassen sich deutliche Indizien für diskriminierende Gruppenkonstruktionen und für eine fehlende Anerkennung der Mehrsprachigkeit von (angehenden) Fachkräften ableiten. Ausgehend von den Befunden werden Handlungsbedarfe für die elementarpädagogische Praxis formuliert.

In the context of the ongoing digitization of interdisciplinary subjects, the need for digital literacy is increasing in all areas of everyday life. Furthermore, communication between science and society is facing new challenges, not least since the COVID-19 pandemic. In order to deal with these challenges and to provide target-oriented online teaching, new educational concepts for the transfer of knowledge to society are necessary. In the transfer project “Zukunftslabor Gesundheit” (ZLG), a didactic concept for the creation of E-Learning classes was developed. A key factor for the didactic concept is addressing heterogeneous target groups to reach the broadest possible spectrum of participants. The concept has already been used for the creation of the first ZLG E-Learning courses. This article outlines the central elements of the developed didactic concept and addresses the creation of the ZLG courses. The courses created so far appeal to different target groups and convey diverse types of knowledge at different levels of difficulty.
Rationale
Playing the trombone can lead to playing-related musculoskeletal disorders (PRMD). Previous research suggests that professional trombonists predominantly struggle with PRMD on the left body side. An increasing volume leads to an increasing contact pressure on the mouthpiece of the trombone, but it is still unclear how the muscle activity relates to this and whether it differs in musicians with PRMD from those without PRMD.
Purpose
The purpose of this study was to investigate the relationship between the activity of different muscles of the left body side, the contact pressure on the mouthpiece and the volume level in healthy trombonists.
Methods
Six male healthy tenor trombonists were included in this study and run through a standardized protocol which consisted of playing a b-flat major scale with three different volume levels (pianissimo, mezzoforte, fortissimo). Analyzed parameters were (1) the activity of several muscles of the left body side (measured with surface electromyography), (2) the contact pressure on the mouthpiece (measured with a force sensor) and (3) the different volume levels.
Results
Analysis of variance reveals significant differences of the muscle activity for the three volume levels. Depending on the volume level and the selected muscle, results show very weak to moderate correlations between contact pressure on the mouthpiece and muscle activity (Spearman´s rho between .11 and .58). The strongest correlation across all muscles occurs during fortissimo playing.
Conclusions
These results show a relationship in healthy trombonists between volume level, contact pressure on the mouthpiece and muscle activity when playing a b-flat major scale. Future research should include trombonists with PRMD to enable comparison between PRMD and non-PRMD musicians.
Educational Objectives:
At the end of the presentation, the participants will be able to…
1. understand the relationship between muscle activity, contact pressure on the mouthpiece and volume when playing the trombone
2. recognize that there are different muscle activity patterns on the left body side when playing the trombone
3. understand that a comprehensive functional diagnosis is important in the management of musicians
This study describes the eHealth4all@eu course development pipeline that builds upon the TIGER educational recommendations and allows a systematic development grounded on scientific and field requirements of competencies, a case/problem-based pedagogical approach and finally results in the syllabus and the course content. The pipeline is exemplified by the course Learning Healthcare in Action: Clinical Data Analytics.
Background:
Neck pain is one of the most common musculoskeletal pains and among the fourth leading causes of years of life lost due to disability, following back pain, depression, and arthralgia. (1)
In the course of their lives, about 70% of all people will experience a clinically relevant episode of neck pain, (2) so finding a good therapy to treat it is of high interest. Aerobic exercise is associated with pain reduction in patients with different types of MSK pain. Recent studies have shown a positive impact of aerobic exercises on brain function, memory processing, cognition, and motor function. (3, 4)
Therefore, the influence of aerobic exercise on pain modulation seems to be of particular interest for individuals with chronic MSK pain, since brain imaging studies have shown that these patients have structural and functional changes, as well as abnormal brain features in various areas of the brain. The evidence regarding the effectiveness of aerobic exercise for neck pain seems limited and outdated.
Thus, a systematic review evaluating the effects of aerobic exercise in patients with neck pain is needed. Therefore, this review aims to investigate the effectiveness of aerobic exercise interventions when compared to other conservative and non-conservative interventions (e.g., localized exercises, medication, acupuncture, physical agents, manual therapy) to decrease pain intensity in people with neck pain.
Materials and methods:
Electronic literature searches were conducted in a total of six databases such as Medline, Embase, CINAHL, Cochrane Library, Web of Science, and Scopus. The review considered randomised controlled trials (RCTs) including patients over 18 years having musculoskeletal pain in the neck area. The Neck Pain Task Force's classification of pain severity describes four levels of neck pain, with the first three levels considered in this review. (5)These must be clinically diagnosed by a health care provider according to signs and symptoms or based on standardized criteria specific for each disease. Studies involving subjects with any pre-existing conditions, previous surgery, or pain not clearly related to the musculoskeletal system were excluded. No limits were applied in terms of sex, ethnicity, and living country. Data were extracted using a standardized data extraction form.
Methodological quality was determined using the Cochrane Collaboration Risk of Bias Tool (CCRBT) and the strength of the evidence with Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Data were extracted and evaluated by two independent reviewers.
Results:
A total of 21585 records were identified and screened independently for eligibility by two reviewers. A total of six unique studies, reported on ten manuscripts met the specified inclusion criteria. Different types of aerobic exercise were used in the studies. Studies included isolated and combined aerobic exercise using interventions such as cycling on an ergometer or walking outdoors at a moderate intensity. Comparison groups were for example strength training or education. The most common outcome was pain assessed with the Visual Analogue Scale (VAS) or the Nordic questionnaire.
The included studies had a high risk of bias and the overall quality of the evidence for this systematic review was considered low. There was high heterogeneity in the included studies regarding interventions applied and study results.
When looking at the effect of aerobic exercise versus control group or other intervention groups measured with VAS, it can be observed, that there was a great heterogeneity between studies results (different magnitudes and directions). Although none of the comparisons showed a statistically significant difference between aerobic exercise and control (MD 6.24 mm, 95% CI [-11.21; 23.96]) or active intervention groups (MD -9.52 mm, 95% CI [-18.48; -0.56]) on pain intensity; it seems that aerobic exercise is slightly better than a control group, and equally effective as other active treatments such as strength exercise or education.
In addition, when combined with other therapeutic modalities, aerobic exercise, could potentially help to reduce pain intensity (MD 7.71 mm, 95% CI [1.07; 14.35]). Especially in the long term, the combination of strength and aerobic exercise showed promising results. Statistically significant differences in favour of aerobic exercise for pre vs. three months follow up (MD 11.20 mm, 95% CI [2.85;19.55]) and pre vs. six moths follow up (MD 15.10 mm, 95% CI [6.99; 23.21]) were found.
Conclusions:
Although there is currently limited evidence on the effectiveness of aerobic exercise in individuals with chronic neck pain, aerobic exercise was found to not only reduce pain intensity, but also to improve disability as well as physical and emotional functioning. However, as the evidence is limited, low quality, and heterogeneous, further research is needed in this area to obtain more accurate results.
Introduction: Hamstring injuries are among the most common injuries in soccer players. Especially the danger of hamstring injuries increases in the final third of each half, with the biceps femoris muscle being highly susceptible, but currently there is no supporting evidence in soccer players. It is important to investigate to provide a basis for further clinical investigations in order to reduce the risk of hamstring injuries.
Objective: To investigate a soccer-specific muscle fatigue protocol has an effect on the activation patterns of the biceps and semitendinosus muscles and correlates with the subjectively perceived exertion of the soccer players.
Methods: 19 healthy soccer players aged 19 - 35 years were included and underwent a standardized procedure that included: (1) performance of the nordic hamstring curls (NHC) and a 10m sprint (pre-test), (2) a soccer-specific muscle fatigue loading protocol for 30 minutes with subsequent rating of perceived exertion (RPE), (3) re-assessed like pre-assessment (post- test). Electromyography (EMG) data were recorded the biceps and
semitendinosus muscles of both legs. Two parameters were analyzed: the peak amplitude during the NHC and the mean amplitude during the 10m sprint.
Results: The RPE score (9.5, p<0.001) and 10m sprint shows significant differences between pre- and post- test for the biceps (standing leg: -82.45, kicking leg: -81.77; p<0.01) and semitendinosus muscle (standing leg: -60.08, p=0.001); kicking leg: -65.30, p=0.03). Significant correlation exists between RPE score and biceps muscles at posttest (standing leg: r=-0.54, kicking leg: r=-0.51; p<0.05).
Conclusion: Muscle fatigue leads to significant changes in the activation behavior of the hamstring muscles. In particular, the biceps muscle shows a correlation with perceived exertion, the higher the exertion, the lower the muscle activity. This may help explain the higher prevalence of the biceps muscle in hamstring injuries and offers a basis for further clinical investigations
Sustainable Digital Entrepreneurship : Examining IT4Sustainability as Business Development Path
(2022)
There is an increasing interest within the field of Information Systems as well as political agendas to identify the potential of digital technologies to promote sustainable development. Nonetheless, sustainable entrepreneurship and digital entrepreneurship are widely treated separately within the literature, suggesting that there is little understanding of how entrepreneurs could employ digital technologies to promote sustainable development. Based on an empirical, qualitative research approach, relying on Grounded Theory methodology, this paper identifies characteristics of sustainable digital entrepreneurs. An investigation of the manifestations of the sustainable digital orientation reveals a rather diffuse understanding of the relation and potential synergy effects. In response to this gap, the paper presents examples on how sustainable digital entrepreneurs employ digital and disruptive technologies to tackle sustainability challenges (IT4Sustainability development path), including information and communication technology, such as digital platforms, artificial intelligence, or drone technology. The presented approaches range from second-mover approaches associated with low digital maturity limited to the business level to the development of new business models facilitating the sustainable transition of whole sectors. These insights are summarized in an IT4Sustainability maturity model, which presents different starting points for entrepreneurs. Relevant theoretical, practical, and policy implications are discussed, especially concerning the education on IT4Sustainability, including Corporate Digital Responsibility.
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.
Background
Citizen energy cooperatives (CECOs) are an important element for realising the transformation of the European energy system from a central system, dominated by a few market players to a decentralized system with the participation of many citizens, in which energy supply is largely based on renewable energy sources. This article identifies success factors that ensure a working organization that is capable of implementing projects to support the energy transition and improving the well-being of citizens.
Methods
The aim of this study is to identify success factors using the example of CECOs in north western Germany through a two-step process. The first step is a literature review to identify success factors of CECOs. Second, 12 semi-structured expert interviews with managers of CECOs are conducted and evaluated by means of a qualitative content analysis. The interviews identified the success factors and barriers of CECOs. The interviews were recorded and transcribed verbatim. The coding process was carried out using a qualitative data analysis software (ATLAS.ti 8.4.5,).
Results
The results show that three factors particular should be present, but can influence each other, to lead to successful CECOs: (1) the CECOs require business models with low complexity, as business models that span different stages of the value chain can overwhelm organizational managers. (2) Committed key individuals must be found and promoted. They need the support of the members. (3) Social and ecological principles are the core values of CECOs. The maintenance and strengthening of social–ecological credibility must be promoted in the public perception.
Conclusions
The results show that CECOs emerge from a strong social cohesion in a society. In addition, local "key individuals" need to be identified and supported. To this end, the framework conditions (e.g., policy, legislation, municipal support, etc.) must be adapted in such a way that these "key individuals" in CECOs are not overburdened. The analysis of the interviews also revealed that political or regulatory barriers are often cited as obstacles to the implementation of community energy projects.
Der Beitrag analysiert den Umgang mit der Covid-19-Pandemie innerhalb der Krankenhäuser und leitet davon Handlungsempfehlungen für das Krankenhausmanagement ab. Dabei geht es sowohl um die Organisation und Ausgestaltung der Patienten- und Personalsteuerung (vorgelagerte Notaufnahmen, Aufnahmestationen, Triage, Covid-19-Testung etc.) als auch um die sich durch die Kontaktbeschränkung ergebene Herausforderung im Umgang mit Besuchern und Lieferanten. Des Weiteren wird auch die betriebswirtschaftliche Steuerung in einer – in allen Belangen – ungewohnten Situation beleuchtet.
background: Musculoskeletal problems (MP) are widespread in performing artists and are due to the special demands of instrument playing, singing or dancing. Additionally, various other factors might contribute to performance-related MP. To provide a specific physiotherapeutic management for performing artists it is important to gain information about the performing art, the individual demands and contributing factors. The subjective examination (SE) is the basis of the clinical reasoning process and the hypothesis forming for further clinical examination and biomechanical analysis. In the present protocol, the SE consists of a questionnaire-based section and an interview-based section and is part of the evaluation process of the neuromusculoskeletal examination of a performing artist specific reference laboratory.
purpose: To develop a standardized SE protocol divided into a questionnaire-based section (Part 1) via web application and an interview-based SE (Part 2) to address MP of performing artists.
methods: The questionnaires for part 1 were selected based on the expertise of the research group and the psychometric properties of each possible questionnaire. A common physiotherapeutic recording of findings which addresses the relevant questions of the SE of MP was used. To adapt the anamnesis to performing-associated MP questions specific to instrument playing, singing and dancing were selected on the basis of a literature search and the expertise of the research group.
summary of content/results: Part 1 consists of three topics. (1) information about the performing art, professional level and sociodemographic data, (2) information about pain and pain processing, and (3) the anatomical location of the main MP including a body region-specific questionnaire. Part 2 is based on the five aspects of clinical practice described by Maitland and the Musculoskeletal Clinical Translation Framework by Mitchell et al. The performing arts specific part is particularly focused on performing art specific considerations, physical and psychosocial contributing factors and art-specific activities.
significance: This standardized SE protocol should help clinicians evaluating the musculoskeletal health of performing artists in a standardized and specific way.
rationale: Musculoskeletal problems are widespread in performing artists and are due to the special demands of instrument playing, singing or dancing. Additionally, various other factors might contribute to performance-related musculoskeletal problems. In order to provide a specific physiotherapeutic management for performing artists, it is important to gain information about the performing art, the individual (biomechanical) demands and contributing factors. The subjective examination is the basis of the clinical reasoning process and the hypothesis forming, which is important for goal setting in further clinical examination and biomechanical analysis. In the present protocol, the subjective examination consists of a questionnaire based section and an interview based section and is part of the evaluation process of the neuromusculoskeletal examination of a performing artist specific reference laboratory.
purpose: The aim of this study was to develop a standardized protocol for an interview based subjective examination of performing artists with musculoskeletal problems. The results of this section of the subjective examination will be combined with the results of the questionnaire based subjective examination , in order to gather as much relevant information as possible to specifically address the individual’s musculoskeletal health status.
methods: A common physiotherapeutic recording of findings which addresses the relevant questions of the subjective examination of musculoskeletal problems was used. In order to adapt the anamnesis to performing-related musculoskeletal problems, questions specific to instrument playing, singing and dancing were selected on the basis of a literature search and the expertise of the research group.
results: The protocol is based on the five aspects of clinical practice described by Maitland and the Musculoskeletal Clinical Translation Framework by Mitchell et al. (2017) .The performing art specific questions especially address (1) performing art specific considerations including style, genre, education and professional level, practice habits, repertoire, and external factors, e.g. concert conditions, (2) performing art specific physical and psychosocial contributing factors, and (3) performing art specific activities which trigger the musculoskeletal problems and help to form hypotheses for the following clinical examination. Individual tracks lead through the subjective examination so that irrelevant questions are skipped depending on the kind of musculoskeletal problem and the performing art practiced by the individual client.
conclusions: A pretest of this standardized anamnesis protocol is ongoing in a special physiotherapy clinic for performing artists since spring 2022. In an iterative approach, the protocol will be continuously improved based on patient feedback and clinical considerations.
Background: Musculoskeletal problems (MP) are widespread in performing artists and are due to the special demands of instrument playing, singing or dancing. In order to specifically evaluate these problems, a reference laboratory is under development. The evaluation covers 4 steps: a subjective examination (SE) including (1) a questionnaire-based online survey and (2) an interview-based anamnesis. On the basis of the results of the SE, hypotheses are formed for (3) an individual musculoskeletal clinical examination and a (4) biomechanical analysis. Here, the focus is on the clinical examination.
Purpose: to develop a standardized protocol for a clinical examination addressing especially musculoskeletal problems in performing artists.
Methods: A common physiotherapeutic clinical examination should be supplemented with techniques, which are specific to performance-related musculoskeletal problems and/or their risk factors. The development was based on a literature search and the clinical expertise of the physiotherapeutic research group.
Summary of content/Results: The performing arts specific clinical examination includes the common analysis of posture as well as passive/active movement capacities and specific differentiating tests in relation to the signs and symptoms of the individual artist. The examination is supplemented by a functional demonstration focusing on the special demands of playing the respective instrument, while singing or dancing. Common overuse risk factors like hypermobility, special anthropometric data or an examination of the motor control of different body regions are addressed. Optional, the various parts of the examination process could be skipped, if not relevant for the individual artist.
Significance: This clinical examination protocol should help clinicians evaluating the musculoskeletal health of performing artists in a standardized and specific way.
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.
Apps have been attested to empower patients regarding disease self-management through numerous studies. However, it is still unclear what factors determine the perception of patients whether an app is a useful tool for this purpose. A multiple regression model that was informed by the Technology Acceptance Model (TAM 2) was tested based on the answers of 235 app users with Diabetes type 1 or 2. The model accounted for 59.2% of the variance of the perceived degree of self-management. Factors belonging to the relevance-usefulness-quality complex as well as factors reflecting the patient’s self-control were found to be significant in the model. Patient demographics, i.e. age, gender, app experience and type of Diabetes did not play any significant role. In conclusion, this study raises the question whether apps should be designed to strengthen self-management in the sense of self-control (e.g. own measurements, diary) as opposed to guiding and advice giving.
Pandemie, Nachfrageschocks und Krieg können Unternehmen an den Rand Ihrer Überlebensfähigkeit treiben. Eine Stärkung der Resilienz und der Nachhaltigkeit ist nachweislich durch Digitalisierung möglich. Aber welche Aspekte der Digitalisierung sind für die unternehmerische Resilienz besonders relevant und werden in der Praxis zielorientiert verfolgt? Diese Arbeit nutzt einen Multimethodenansatz, bestehend aus einem systematischen Literaturreview sowie aus semi-strukturierten Experteninterviews, um die obigen Fragen zu adressieren. Die Ergebnisse indizieren, dass aktuell die drei Themenfelder Dynamic Pricing, Process Mining und Self-Service Reporting/BI besonderen Fokus genießen. Andere Themenfelder hingegen, wie Neurale Netze, Blockchain Technologie, Gamification oder Text Mining werden in der Literatur zwar intensiv diskutiert, finden in der Praxis allerdings nach wie vor selten Einzug.
With the start of the 21st century, patient safety as a topic of special interest has attracted increasing attention in both academia and clinical practice. As technology has continued to develop since then, questions and focal points surrounding the topic have also shifted. In particular, questions regarding the impact of digitalization on patient safety and its measurement are now of high interest. This work aims to develop a maturity assessment instrument in the form of a criteria set for measuring structural requirements for digital patient safety in hospitals. Based on the results of a literature review and a derivation of maturity objects (MO) from known maturity models, 64 criteria across 11 categories were developed. Written comments of two digital patient safety experts as well as subsequent interviews were used to evaluate and refine the criteria catalog. The resulting catalog offers hospitals guidance for detecting possible areas of structural improvements in their information systems with regard to patient safety and represents a unique instrument for assessing digital maturity in this particular area.
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.
This new edition of the classic textbook on health informatics provides readers in healthcare practice and educational settings with an unparalleled depth of information on using informatics methods and tools. However, this new text speaks to nurses and -- in a departure from earlier editions of this title -- to all health professionals in direct patient care, regardless of their specialty, extending its usefulness as a textbook. This includes physicians, therapists, pharmacists, dieticians and many others. In recognition of the evolving digital environments in all healthcare settings and of interprofessional teams, the book is designed for a wide spectrum of healthcare professions including quality officers, health information managers, administrators and executives, as well as health information technology professionals such as engineers and computer scientists in health care. The book is of special interest to those who bridge the technical and caring domain, particularly nurse and medical informaticians and other informaticians working in the health sciences. Nursing Informatics: An Interprofessional and Global Perspective contains real-life case studies and other didactic features to illustrate the theories and principles discussed, making it an ideal resource for use within health and nursing informatics curricula at both undergraduate and graduate level, as well as for workforce development. It honors the format established by the previous editions by including a content array and questions to guide the reader. Readers are invited to look out of the box through a dedicated global perspective covering health informatics applications in different regions, countries and continents.
Normative Orientierung

Rationale:
Neck pain is a large health problem worldwide and often seen in musicians [1, 2]. Neck pain can radiate into the arm due to various underlying pain types and pain mechanisms making it heterogeneous in clinical signs and symptoms [3-5]. On the one hand, patients may present with dominant nociceptive neck-arm pain caused by activation of the nociceptors in muscles, joints, ligaments, fascia, tendons and the connective tissues of a nerve [6, 7]. Activation of nociceptors in nerve connective tissues may cause clinical signs of heightened nerve mechanosensitivity what is per definition categorized as nociceptive pain [6, 8, 9]. On the other hand, patients may present with dominant neuropathic pain, defined as pain as a direct consequence of a lesion or disease affecting the somatosensory system [10, 11]. The clinical profile of these different pain types is sometimes difficult to disentangle based on the localization and pain character [12]. Moreover, non-specific neck-arm pain patients shown a neuropathic pain component based on somatosensory changes detected via Quantitative Sensory Testing (QST) [3, 13]. Classifications with a defined physical examination pathway can be helpful to define subgroups to guide the clinical decision making [14]. This workshop updates the background about the pathophysiology of neck-arm pain and mediates an evidence-based examination to classify patients.
Purpose:
The aim of this workshop is to give a current insight into the background and evidence of neck-arm pain and to plan and practice a physical examination.
Content of Presentation:
This workshop will summarize evidence of neck-arm pain. Thereupon, current evidencebased diagnostic options will be presented and practiced together. Finally, a short insight in the management of neck-arm pain will be given.
Approach of Presentation:
QST testing and current cost-effective evidence-based methods will be presented to identify neuropathic components in neck-arm pain. Selected methods will be performed practically together, e.g. bedside sensory testing and neurodynamic tests.
Clinical Significance:
After the workshop, participants will have improved skills to diagnose in the spectrum of neck-arm pain for musicians with neck-arm pain.
At the end of the presentation, the participants will be able to:
- understand the heterogeneity of neck-arm pain,
- plan an appropriate diagnostic physical examination,
- have an insight in possible management strategies.
Obwohl sich die Anforderungen im Sport und dem Musizieren ähneln, ist die Musikerphysiotherapie längst nicht so entwickelt wie die Sportphysiotherapie. Dabei lassen sich die sogenannten „Performance-Related Musculoskeletal Disorders“ erfolgreich mit Manueller Therapie oder Physiotherapie, z. B. mit Hilfe einer Bewegungsanalyse, therapieren. Prof. Dr. med. Christoff Zalpour gibt einen Überblick über das Feld der Musikerphysiotherapie, deren Potenzial noch lange nicht vollends erschlossen ist.
Rationale:
Instrumentalists often suffer from playing-related (neuro-)musculoskeletal disorders (PRMDs). Most common PRMDs in string players are related to upper-body regions. Motion analysis has proven to be helpful in the evaluation of functional disorders. It was already shown that it is a valid and clinically feasible tool for accurate, repeatable, and objective assessments of functional movement in string players. Thus, it may guide clinicians to improvements in injury prevention, diagnosis, and treatment. Nevertheless, its application in clinical consultation is still very uncommon. For this reason, there is a lack of well-established motion analysis protocols for the examination of PRMDs in string players using advanced biomechanical instruments in clinical settings.
Purpose:
To demonstrate the development and application of a motion analysis protocol for the evaluation of functional upper-body movements in violinists, violists, and cellists in a clinical setting for the investigation of PRMDs.
Approach:
The protocol was to be integrated into a clinical reasoning process for testing clinical hypotheses and evaluating treatment outcomes in physiotherapy. As a starting point, a primary clinical question was defined, and then, specific upper-body symptom regions as well as measurement parameters (relative rotation angles and muscle activities over time) were identified. Subsequently, involved segments, joints, and muscles were assorted. For quantification of upper-body kinematics a novel, marker-based method was used which provides multi-segmented shoulder and spine models while providing simple application. Based on that, a comprehensive mechanical model of the upper body as well as the associated coordinate systems and rotation sequences were specified. This further guided both, the definition of a custom-made marker set as well as the selection and placement of surface electrodes. Furthermore, required static and functional calibration trials as well as movement tasks for functional assessment were specified. Finally, advanced approaches, such as a comprehensive kinematic model and functional determination of joint centers and axes were established for extraction. Then, outcome parameters and their form of representation were determined for further analysis and interpretation.
The application of the method first includes the selection of segments, joints, and muscles to examine – originating from one or more clinical (working) hypotheses or symptom regions. This drives the configuration and placement of required surface markers and electrodes. Then, the required calibration and functional movement trials are executed. After measurement, the outcome parameters get extracted and analyzed. Based on the results the hypothesis is discarded or verified.
Content:
The method was applied to a violinist (female; 18 years old; 13 years of experience; practicing 2 to 3 hours per day, 7 days per week) with playing-related demands in the left cervical-shoulder-arm region.
Subjective findings indicated that the pain regularly occurred after 30 minutes of playing fast or difficult musical pieces. Physical examination showed that strength testing of left serratus anterior muscle caused pain, lower trapezius muscles seemed weak, forearm muscles were sensitive to pressure, movement of the cervical spine to the left was reduced, and upper limb neural tension test was noticeable.
This led to the following working hypothesis: Neck-related arm pain with neurodynamic component and motor control problem in the scapulothoracic region. Thus, left-sided cervical-shoulder-arm region was selected for functional examination.
Optoelectronic motion capture system and surface electromyography were used for data collection. Static and function calibration trials as well as functional assessment trials (chromatic scale with different tempi) were conducted. Afterwards, data was further processed, and outcome parameters were extracted.
Results showed that greater tempo and pain had an impact on the rotation angles and muscle activities. They led to less overall joint movement and range of motion, to less muscle activity in the forearm muscles, and to greater activity inputs in the scapulothoracic muscles. Overall, greater tempo and pain led to a different motor program which verified the working hypothesis.
The procedure was repeated after treatment (four appointments over one week) with manual therapy, training, and education. The pre-/post-interventional comparison showed changes in the motor program. There was noticeable higher mean activity in upper trapezius and deltoid muscles and simultaneously less in the remaining ones. In addition, only marginal differences in ranges of motion and muscle activity inputs were found between tempi. The playing style appeared to be more stable now. Overall, it appeared that nearly the same motor program was used for each tempo.
Clinical Implications:
Potential applications are intraindividual evaluations of simultaneously joint and muscular function in string players during clinical consultation. It is intended to contribute to the diagnosis of PRMDs in terms of an objective, comprehensive and yet clinically feasible diagnostic assessment as well as pre-post-intervention outcome evaluation.
Nonetheless, motion analysis must be used with care in clinical decision making. Motion data is subject to both, intraindividual variations, and measurement errors. In addition, the smallest clinically relevant changes are not clear yet. Therefore, results should only be interpreted together with other clinical findings.

Hypothesis/Aims of study
Many results related to the effectiveness of surgical and non-surgical proce- dures for treating urinary incontinence (UI) are reported in the literature. Following the principles of evidence based-practice, besides the interpreta- tion of study results based on statistical significance, authors should consid- er evaluating the clinical relevance of treatment effects in this field.
The minimal important difference (MID) of clinical outcomes could be used to assess the clinical relevance of interventions. MID is defined as “the small- est difference in score in the domain of interest that patients perceive as important, either beneficial or harmful, and which would lead the clinician to consider a change in the patient’s management’’[1]. One common way to obtain MID for outcomes of interest is by using anchor-based methods. These methods apply one anchor that analyzes the change in the patient's health status according to the patient’s perception.
However, MIDs should be provided according to appropriate calculations and methods and based on the definition of a MID. However, there are a lot of misconceptions and misunderstandings related to the MID. These mis- understandings have led to incorrect reports of these values. Moreover, it is still not known which criteria the authors considered during the analysis of the MID in the Women’s Health area. Therefore, with this preliminary re- port, we aimed to identify and report all anchor-based methods to estimate MIDs for outcomes measures related to UI available in the literature; and analyze which concepts and levels of improvement in the health status of the patient have been considered by the authors to calculate the MID.
Study design, materials and methods
This systematic review was conducted according to PRISMA guide- lines. The study protocol was registered in the PROSPERO database (CRD42022299686). A systematic search was performed using Ovid Med- line, Embase, Web of Science, and Scopus from May to June 2021. Any study generating MIDs for UI that included women with more than 18 years, stress urinary incontinence (SUI), urgency urinary incontinence (UUI) and/ or miXed urinary incontinence (MUI) was included. The primary outcome was the MID for outcomes related to UI. No limits were applied on the data- bases for the date, language or publication range.
Studies were classified into three categories according to the level of im- provement in health status assessed by the anchor and considered by the authors during the MID calculation: 1) slight improvement: if authors in- cluded participants that evaluated their health status as “a little better” in their analysis; 2) moderate improvement: if authors considered women that reported a “better” or a “much better” status of the condition; or 3) strong imporvement: if all patients that improved (“very much better” or if authors grouped all the patients that improved in one single category) were consid- ered in one group against other group that did not report any improvement. After classifying the papers, we counted and reported how many studies were considering only the minimal level of improvement to reported the MID, according to previous definition and recommendation.
The initial electronic search resulted in a total of 1,662. After removing du- plicates (n=719), 943 were screened, and at the end of the selection stages, nine papers that reported anchor-analysis were included in this preliminary report. Seven studies included women with SUI (total sample size= 2,436), while one study included only women with UUI (n=307), and the other one evaluated women with SUI and MUI (n=288). SiX studies analyzed data and provided the MID after a non-surgical treatment of UI, while three analyzed the results after surgery to correct UI. Eleven different questionnaires to measure the patient-related outcomes related to UI with their MIDs were identified. All the tools were related to measuring the impact, distress, or quality of life of women with UI.
Different anchors were used to analyze MID, including scales that evaluated the improvement and satisfaction of the patient, and the visual analogue scale, measures of urinary leakage and questionnaires that measure the se- verity and impact of UI. The MID of siX tools was determined according to the smallest difference detected by the patients, using the Patient Global Im- pression of Improvement questionnaire and the self-reported satisfaction to assess the change of the condition. Most of the MIDs (n=28, 80%) were mis- calculated considering a moderate or a strong improvement of the patients, and not a minimal improvement as suggested by the literature (Table 1).
Interpretation of results
Although previous systematic reviews have reported the psychometric prop- erties of different questionnaires to measure UI outcomes, this is the first study to analyze methods of obtaining MIDs for UI outcomes from the pa- tients perspective (anchor based methods). All the tools with their respec- tives MIDs were related to the impact, distress, and/or quality of life of women with UI. The use of these outcomes measures is in line with the as- sociated impairments of social, psychological, financial, and sexual aspects of a women’s life produced by UI.
Most of the authors in this field did not consider the smallest difference identified by the participants to calculate the MID, which does not follow the original definition of MID proposed by Jaeschke et al.,1 This could gen- erate underestimation or over-estimation of MID, which may directly im- pact the interpretation of the findings from the clinical trials[2] and biased interpretation of the results of the clinical significance from the interven- tions used to manage female UI. Therefore, the interpretation of the clinical significance related to UI outcomes should be done with caution.
Concluding message
Few studies that aimed to calculate the MID using anchor-based methods for outcomes related to female UI were found in the literature. Eleven different questionnaires to measure the outcomes related to UI with their MIDs were identified. However, most studies had not considered the smallest change of improvement (as perceived by the patients) in their analysis, which does not follow the definition of the MID. This could impact decision making. Future research should provide clear guidelines on how to calculate, report, and interpret MIDs in this field.
Wohl kaum ein Thema wird uns in den nächsten Jahren in der Eignungsdiagnostik so intensiv beschäftigen, wie der Einsatz der Künstlichen Intelligenz (KI). Dabei bewegt sich die veröffentlichte Meinung auf einem Kontinuum zwischen Begeisterung und Verdammnis. Den einen erscheint die Künstliche Intelligenz als geradezu perfekte Alternative zur chronisch defizitären Personalauswahlpraxis. Andere sehen hingegen bereits die Herrschaft des Computers, über den Menschen, am Horizont aufziehen. Wieder andere wittern ganz einfach nur das große Geschäft. Doch wie sieht die Realität aus? Wo liegen die Chancen und wo die Risiken der neuen Technologie. Kann eine Software auf der Basis von Internetdaten abgesicherte Persönlichkeitsprofile von Menschen erstellen? Diese und weitere Fragen sollen im Folgenden beantwortet werden.
