The FARSEEING real-world fall repository: a large-scale collaborative database to collect and share sensor signals from real-world falls

Background

Real-world fall events objectively measured by body-worn sensors can improve the understanding of fall events in older people. However, these events are rare and hence challenging to capture. Therefore, the FARSEEING (FAll Repository for the design of Smart and sElf-adaptive Environments prolonging Independent livinG) consortium and associated partners started to build up a meta-database of real-world falls.

Results

Between January 2012 and December 2015 more than 300 real-world fall events have been recorded. This is currently the largest collection of real-world fall data recorded with inertial sensors. A signal processing and fall verification procedure has been developed and applied to the data. Since the end of 2015, 208 verified real-world fall events are available for analyses. The fall events have been recorded within several studies, with different methods, and in different populations. All sensor signals include at least accelerometer measurements and 58 % additionally include gyroscope and magnetometer measurements. The collection of data is ongoing and open to further partners contributing with fall signals. The FARSEEING consortium also aims to share the collected real-world falls data with other researchers on request.

Conclusions

The FARSEEING meta-database will help to improve the understanding of falls and enable new approaches in fall risk assessment, fall prevention, and fall detection in both aging and disease.

     

Du vent dans le ciel de plomb ? L’accès des femmes aux professions supérieures, xix-xx siècles

Women with diplomas, authority, power, in the professions, in top jobs… Nowadays, since demands have taken shape around the concepts of “parities” or quotas, the phases in the process whereby women have gained access to top positions in employment risk being overlooked. This process stretches out over a long time, even though Western European countries have passed through successive phases at about the same time. The years 1880, 1920, 1970 and 2000 stand out like landmarks in this conquest starting out from equal access to education and continuing through the slow mixing of the two sexes in various types of jobs, medical, technical, legal, military or political. Till the last decades of the 20th century, feminists (men as well as women) fought for these advances despite the scorn of those men and women who wanted to see women confined to the jobs “fit for them”, in particular in education and care-giving.     

Qualitätsmanagement: Entwicklung,Problemfelder und ein integrativer Lösungsvorschlag

Quality Management: History, problems and an integrative modelStarting with a critical examination of the history and the commonly known concepts and systems of Quality Management, the paper discusses a broader understanding of quality in a genuinely managerial perspective. This is shown by generating and applying five basic dimensions of the quality concept. An integrative concept of Quality Management is presented.     

Einsatz von Simulationspatienten im Kommunikations- und Interaktionstraining für Medizinerinnen und Mediziner (Medi-KIT): Bedarfsanalyse — Training — Perspektiven

Communication skills are of central importance within daily medical life providing effective treatment. In the modern high-tech field of medicine, trustful conversations play a prominent role. In order to help students of the Heidelberg Medical Faculty to be ready for their highly responsible role as communication partner, training is carried out in the framework of HeiCuMed (short for Heidelberger Curriculum Medicinale) using specially trained simulation patients. The communication and interaction training program (referred to as Medi-KIT) enables to practice conducting conversations with challenging communication partners and grave conversational content in difficult situations. Feedback from the standardized patients, as well as from peers and tutors represents a central didactic element.In order to secure knowledge transfer into daily clinic life and as well to build a relation to cognitive knowledge transfer, all medical students are assigned, alongside Medi-KIT lessons, to a ward, and training units are coordinated in terms of content to correspond with symptom-oriented lectures and parallel POL-groups (problem-oriented learning groups). In addition, communication learning objectives are examined at the end of the semester in the form of a clinical practical exam (OSCE: Objective Structured Clinical Examination) and at patient’s bedside (Mini-CEX: Mini Clinical Examination). The goal in imparting communication skills within medical education is that the longitudinal communication curriculum be maintained and continued in subsequent medical specialization studies.     

Die quantitative Bestimmung kultureller Unterschiedlichkeit in Europa

Research on transnationalization and by some sociological fields tries to explain the varying intensity of bonds between countries. Cultural similarity is often regarded as relevant, but an empirical control of this influence is missing. This article suggests an index on cultural similarity to fill this gap. Based on questions in the European Social Survey implementing the value dimensions of Shalom Schwartz, the index is defined as the general discriminant measure Wilks?? Lambda of a pair-wise discriminant analysis. The index is controlled for intertemporal stability and correlated with similarity of languages, which has been proposed for measuring cultural similarity. Also other plausible patterns of cultural similarities are assessed with the index, i.e. spatial distance, religious heritage and political blocs. The index opens up the possibility of empirically assessing the influence of cultural similarity on transnational bonds and also allows for an empirical control of Parsons?? famous thesis, that value consent is needed for social integration.     

Charisma and organizational change: A multilevel study of perceived charisma,commitment to change,and team performance

What makes people perceive a leader as charismatic, and how do team leaders obtain performance outcomes from their followers? We examine leaders in times of organizational change and investigate the mechanisms through which leaders' change-promoting behaviors are associated with team performance. In a multilevel mediation model, we propose that the indirect relationship between change-promoting behaviors and team performance is sequentially transmitted through followers' perceptions of charisma and followers' commitment to change. A study of 33 leaders and 142 followers provides empirical support for the model, using multilevel structural equation modeling to analyze top-down relationships between leaders and followers and bottom-up relationships between followers and team outcomes. Results suggest that team leaders are perceived as more charismatic when they engage in change-promoting behaviors. These behaviors facilitate team performance through individual followers' perceived charisma and commitment to change.     

Adorno und die autoritäre Persönlichkeit

“The Authoritarian Personality” is a milestone study in social science research. Based on a series of research and investigations, the study, conducted in 1945/46, had to pass controversies and delays until its publication in 1950. Theodor W. Adorno’s involvement in this research appears to be less central than has frequently been assumed. Gradually, the importance of Erich Fromm’s contribution to the theoretical foundation and methodology of the study was recognized. Nevertheless, in many publications it is still acceptable to neglect the major contribution of Erich Fromm and Adorno’s further co-authors, Else Frenkel-Brunswik, Daniel J. Levinson and R. Nevitt Sanford. During the fifties, the Frankfurt Institut für Sozialforschung (IfS) conducted only two large-scale interview-and questionnaire-based studies pertaining to authoritarian personality issues. However, in further studies innovative research perspectives were not evident, and the most obvious task, to investigate former perpetrators and supporters of National Socialism, was not realized. The most probable of these deficit motives were based on Adorno’s dismissive view of empirical social psychology and differential psychology. However, the expertise of both are indispensable for such research programs. This historical review of “The Authoritarian Personality” demonstrates why there has been so little innovative and comprehensive research on the subject in postwar Germany.     

Local principal curves

Principal components are a well established tool in dimension reduction. The extension to principal curves allows for general smooth curves which pass through the middle of a multidimensional data cloud. In this paper local principal curves are introduced, which are based on the localization of principal component analysis. The proposed algorithm is able to identify closed curves as well as multiple curves which may or may not be connected. For the evaluation of the performance of principal curves as tool for data reduction a measure of coverage is suggested. By use of simulated and real data sets the approach is compared to various alternative concepts of principal curves.
