Results from the EU-project iStoppFalls : feasibility, effectiveness, approach for fall prevention
(2016)
Noch sind sich die Experten nicht einig, wie schnell Blockchain das Internet revolutionieren wird. Dass das Potenzial dafür riesig ist, ist sich Professor Jens Böcker sicher. Er unterhält eine Professur für Betriebswirtschaftslehre und Marketing an der Hochschule Bonn-Rhein-Sieg und forscht zu diesem Thema.
Background: Falls are common in older adults and can result in serious injuries. Due to demographic changes, falls and related healthcare costs are likely to increase over the next years. Participation and motivation of older adults in fall prevention measures remain a challenge. The iStoppFalls project developed an information and communication technology (ICT)-based system for older adults to use at home in order to reduce common fall risk factors such as impaired balance and muscle weakness. The system aims at increasing older adults’ motivation to participate in ICT-based fall prevention measures. This article reports on usability, user-experience and user-acceptance aspects affecting the use of the iStoppFalls system by older adults.
Methods: In the course of a 16-week international multicenter study, 153 community-dwelling older adults aged 65+ participated in the iStoppFalls randomized controlled trial, of which half used the system in their home to exercise and assess their risk of falling. During the study, 60 participants completed questionnaires regarding the usability, user experience and user acceptance of the iStoppFalls system. Usability was measured with the System Usability Scale (SUS). For user experience the Physical Activity Enjoyment Scale (PACES) was applied. User acceptance was assessed with the Dynamic Acceptance Model for the Re-evaluation of Technologies (DART). To collect more detailed data on usability, user experience and user acceptance, additional qualitative interviews and observations were conducted with participants.
Results: Participants evaluated the usability of the system with an overall score of 62 (Standard Deviation, SD 15.58) out of 100, which suggests good usability. Most users enjoyed the iStoppFalls games and assessments, as shown by the overall PACES score of 31 (SD 8.03). With a score of 0.87 (SD 0.26), user acceptance results showed that participants accepted the iStoppFalls system for use in their own home. Interview data suggested that certain factors such as motivation, complexity or graphical design were different for gender and age.
Conclusions: The results suggest that the iStoppFalls system has good usability, user experience and user acceptance. It will be important to take these along with factors such as motivation, gender and age into consideration when designing and further developing ICT-based fall prevention systems.
Marketing und Recht kompakt
(2016)
"Marketing und Recht - was soll das denn?" So oder ähnlich wird der eine oder andere auf den Titel des vorliegenden Buches spontan reagieren. Das verwundert nicht, ist die Buch-Landschaft doch vor allem dadurch geprägt, dass Marketing-Werke und Abhandlungen zu marketingrelevanten Rechtsthemen am Büchermarkt stets "getrennt marschieren". Wer Marketingkonzepte entwirft, Vorhaben im Rahmen der Marketingforschung durchführen will oder beabsichtigt, Entscheidungen im Rahmen des Marketings zu treffen, sollte unseres Erachtens möglichst frühzeitig die gängigen "juristischen Fallstricke" erkennen und in seinen Überlegungen berücksichtigen.
Within qualitative interviews we examine attitudes towards driverless cars in order to investigate new mobility services and explore the impact of such services on everyday mobility. We identified three main issues that we would like to discuss in the workshop: (I) Designing beyond a driver-centric approach; (II) Developing mobility services for cars which drive themselves; and (III) Exploring self-driving practices.
Mobilitäts- und Nachhaltigkeitsforscher sehen sich bei der Erforschung des Mobilitätsverhaltens von Personen mit einer bunten Palette an Erhebungsmethoden konfrontiert. Erweitert wird diese Vielfalt in der letzten Zeit durch die Möglichkeit, dieses Verhalten direkt über die Smartphones der Probanden zu erfassen. Um die Auswahl geeigneter Methoden zu erleichtern, liefert die vorliegende Literaturstudie einen detaillierten Überblick zu Fragestellungen, Daten und Erhebungsmethoden, die im Bereich der Mobilitätsforschung zur Erfassung von Alltagsmobilität eingesetzt werden.
Dieser Artikel stützt sich auf das vom 13.10.2015 bis 12.01.2016 gemeinsam durchgeführten Praxisprojekt von ORBIT und der Hochschule Bonn-Rhein-Sieg. Thema des Projekts waren die Methodenevaluation und Automatisierung von Auswertungsprozessen. Speziell ging es um die Überprüfung der von ORBIT entwickelten Methodik zur Anforderungsanalyse und Standortbestimmung – dem ORBIT-Navigator.

Companies often have difficulties determining which criteria to base their investment decisions in different countries on. When considering direct foreign investment several risk indices are available. The PCI (Peren-Clement-Index) in its original form was developed in 1998. Its further refinement improves the PCI in three major ways: First, it offers a dynamic adjustment of criteria and consideration of recent changes in the international environment. Second, it provides business specificities of a company or its industrial sector to be considered in addition to macroeconomic aspects by a two-dimensional presentation, which ensures a customized assessment. Third, the PCI allows for consolidating investment decisions by combining a resource-orientated with a market-oriented view. The PCI allows, unlike other indices, a customized and company-specific strategic planning process. Ultimately companies must take up both perspectives in the context of an international investment decision. The use of risk indices in corporate planning for assessing global investments decision creates a fundamentally new of risk assessment.

A central objective of the German gambling law is to ensure the protection of minors and players (§ 1 Sentence 1 No. 3 GlüStV 2012). Since the year 2014 gambling facilities for commercial games of chance in gambling halls and restaurants have been certified by the German Safety Standards Authority [Technischer Überwachungsverein – TÜV]. Certification by government-accredited testing organizations based on internationally validated, interdisciplinary scientific expertise "Safeguarding the Protection of Minors and Players with Respect to Commercial Gambling in Germany – 2.0" is a quality assurance instrument from a regulatory perspective. It is in the interests of, in particular, excellent quality providers to ensure that they are also perceived as providing this level of quality. Certification leads to market separation. In so doing, the advantages of end-to-end certification should be greater than any disadvantages. Analysing the international environment shows that certifi cation initiatives are necessary and have been put in place in other sectors of the gambling industry.
The primary aim is quality assurance for a responsible handling of commercial games of chance offerings (responsible gambling). The presented testing catalogue for commercial gambling can also provide an impetus in the international context and, as appropriate, a set standard.
