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.

     

Tax differentiation,lobbying, and welfare

To what extent a taxing authority should be granted the power to impose different tax schedules to different groups of taxpayers? Although the policy maker aims at maximizing social welfare, her tax policy may be distorted by the lobbying activity of taxpayers. In this political environment we characterize the conditions under which social welfare can be increased by restricting the set of tax instruments available to the policy maker; i.e., the scope of tax differentiation. We show that full differentiation is more costly, in terms of welfare distortions, when the lobbies are asymmetric in size, while minimal differentiation is more costly when the tax bases are asymmetric across different groups.     

Perspektivwechsel und introvisionsorientierte Fallanalysen als gesundheitsf?rderliches Element der Lehrerbildung

The discussion of educational professionalization actually focuses on concepts of health promotion instead of disease prevention (e.g., Dauber und D?ring-Seipel, Salutogenese in Lehrberuf und Schule (SALUS), 2008). This paper follows the direction in presenting a method of promoting salutogenesis development (Antonovsky, Salutogenese. Zur Entmystifizierung der Gesundheit, 1997) by case reflections. These case reflections consist of a change of perspectives and of an approach of mental selfregulation called Introvision.     

Paradox in Public Relations: Why Managing Relating Makes More Sense Than Managing Relationships

This article applies research on paradox, semantics, and theories of groups and logical types to public relations, particularly the concept of relationship management. Paradoxes create tension and are often produced by semantic disturbances resulting from errors in logical typing. Communication is inherently paradoxical. The article contends that progress in public relations practice and scholarship has been inhibited by a failure to recognize or reconcile paradoxes associated with popular concepts, such as relationship management, mutually beneficial relationships, and symmetrical communication. Such concepts breach levels of communication to create logical fallacies and place practitioners into a double bind of promising more than they can deliver without resorting to coercion and manipulation. The article introduces Group Theory and the Theory of Logical Types, and suggests that public relations reframe relationship management with relating management, a practices more consistent with Kant's humanity imperative.     

A Social Networks Approach to Public Relations on Twitter: Social Mediators and Mediated Public Relations

This study proposes theoretical and practical frameworks to systematically examine mediated public relations in social media spaces. We applied a social network conceptual framework to identify and characterize social mediators that connect the US State Department with its international public. The results showed that social mediators vary in terms of their formality and interdependence. Formal social mediators were primarily US government agencies while informal social mediators were nongovernmental organizations (NGOs) and individuals. Notably, relationships with populations in the Middle East and North Africa were mediated primarily by informal actors, and formal mediators played a key role in connecting the public with everywhere else in the world. Government-related formal mediators and informal social mediators showed similar levels of bilateral relationships. In contrast, news media, the most traditional public relations mediators, were rarely found as social mediators and demonstrated the most unilateral relationships.     

100 key research questions for the post‐2015 development agenda

The Sustainable Development Goals (SDGs) herald a new phase for international development. This article presents the results of a consultative exercise to collaboratively identify 100 research questions of critical importance for the post‐2015 international development agenda. The final shortlist is grouped into nine thematic areas and was selected by 21 representatives of international and non‐governmental organisations and consultancies, and 14 academics with diverse disciplinary expertise from an initial pool of 704 questions submitted by 110 organisations based in 34 countries. The shortlist includes questions addressing long‐standing problems, new challenges and broader issues related to development policies, practices and institutions. Collectively, these questions are relevant for future development‐related research priorities of governmental and non‐governmental organisations worldwide and could act as focal points for transdisciplinary research collaborations.
