Understanding the Sharing Economy: The Role of Response to Negative Reviews in the Peer-To-Peer Accommodation Sharing Network?

Recognizing the potentially ruinous effect of negative reviews on the reputation of the hosts as well as a subjective nature of the travel experience judgements, peer-to-peer accommodation sharing plat-forms, like Airbnb, have readily embraced the “response” option, empowering hosts with the voice to challenge, deny or at least apologize for the subject of critique. However, the effects of different re-sponse strategies on trusting beliefs towards the host remain unclear. To fill this gap, this study focus-es on understanding the impact of different response strategies and review negativity on trusting be-liefs towards the host in peer-to-peer accommodation sharing setting utilizing experimental methods. Examination of two different contexts, varying in the controllability of the subject of complaint, re-veals that when the subject of complaint is controllable by a host, such strategies as confession / apol-ogy and denial can improve trusting beliefs towards the host. However, when the subject of criticism is beyond the control of the host, denial of the issue does not yield guest’s confidence in the host, where-as confession and excuse have positive influence on trusting beliefs.

Competence-Mapping CDE : Resultate einer Umfrage im Herbst 2009

Anlässlich einer CDE Retraite im Frühjahr 2009 wurde die Frage der Entwicklung von Kompetenzen am CDE diskutiert. Eine Schlussfolgerung war, dass es notwendig sei, eine systematischeren Umgang mit diesem Thema zu entwickeln. Eine Arbeitsgruppe wurde eingesetzt, welche einen Vorschlag erarbeitete, wie ein Kompetenz-Mapping durchgeführt werden sollte. Im Herbst 2009 wurde entsprechend diesem Vorschlag unter den Mitarbeitenden des CDE eine Umfrage zur Erfassung des Ist-Zustandes betreffend Kompetenzen durchgeführt.

Bridging Research and Development : Partnership Actions for Mitigating Syndromes (PAMS) in the Swiss National Centre of Competence (NCCR) North-South - Capitalising on Experience

Within the framework of Switzerland’s international NCCR North-South research programme, Partnership Actions for Mitigating Syndromes (PAMS) are a practice-oriented component with a transdisciplinary approach. By linking research and development practice, they bring together researchers, practitioners and local communities in a common effort to test and evaluate research findings in concrete development contexts. They provide unique insights into innovative approaches and opportunities for promoting sustainable development in countries of the South and East. After an initial four-year phase, the PAMS projects implemented to date were evaluated in order to learn about their potentials and limits, as well as to decide on the direction of the component for the next phase of the programme. The present publication presents the results of this evaluation.

Meta-cognition about biological sex and gender-stereotypic physical appearance: Consequences for the assessment of leadership competence

Previous findings are inconsistent with regard to whether men are judged as being more or less competent leaders than women. However, masculine-relative to feminine-looking persons seem to be judged consistently as more competent leaders. Can this different impact of biological sex and physical appearance be due to the disparate availability of meta-cognitive knowledge about both sources? The results of Study 1 indicated that individuals possess meta-cognitive knowledge about a possible biasing influence of persons’ biological sex, but not for their physical appearance. In Study 2, participants judged the leadership competence of a male versus female stimulus person with either masculine or feminine physical appearance. In addition, the available cognitive capacity was manipulated. When high capacity was available, participants corrected for the influence of stimulus persons’ sex, but they fell prey to this influence under cognitive load. However, the effect of physical appearance was not moderated by cognitive capacity.

Cost-effectiveness of peer role play and standardized patients in undergraduate communication training.

BACKGROUND The few studies directly comparing the methodological approach of peer role play (RP) and standardized patients (SP) for the delivery of communication skills all suggest that both methods are effective. In this study we calculated the costs of both methods (given comparable outcomes) and are the first to generate a differential cost-effectiveness analysis of both methods. METHODS Medical students in their prefinal year were randomly assigned to one of two groups receiving communication training in Pediatrics either with RP (N = 34) or 19 individually trained SP (N = 35). In an OSCE with standardized patients using the Calgary-Cambridge Referenced Observation Guide both groups achieved comparable high scores (results published). In this study, corresponding costs were assessed as man-hours resulting from hours of work of SP and tutors. A cost-effectiveness analysis was performed. RESULTS Cost-effectiveness analysis revealed a major advantage for RP as compared to SP (112 vs. 172 man hours; cost effectiveness ratio .74 vs. .45) at comparable performance levels after training with both methods. CONCLUSIONS While both peer role play and training with standardized patients have their value in medical curricula, RP has a major advantage in terms of cost-effectiveness. This could be taken into account in future decisions.

Music Piracy on Peer-to-Peer Networks

Content providers from the music industry argue that peer-to-peer (P2P) networks such as KaZaA, Morpheus, iMesh, or Audiogalaxy are an enormous threat to their business. They furthermore blame these networks for their recent decline in sales figures. For this reason, an empirical investigation was conducted during a period of 6 weeks on one of the most popular files-sharing systems, in order to determine the quantity and quality of pirated music songs shared. We present empirical evidence as to what extent and in which quality music songs are being shared. A number of hypotheses are outlined and were tested. We studied, among other things, the number of users online and the number of flies accessible on such networks, the free riding problem, and the duration per search request. We further tested to see if there are any differences in the accessibility of songs based on the nationality of the artist, the language of the song, and the corresponding chart position. Finally, we outline the main hurdles users may face when downloading illegal music and the probability of obtaining high quality music tracks on such peer-to-peer networks.

National competence center for wildlife diseases in Switzerland: Mandate, development and current strategies.

The need for wildlife health surveillance has become increasingly recognized. However, comprehensive programs which cover a wide spectrum of species, pathogens and geographic areas are still lacking in most European countries and practical examples of systems in place remain scarce. This article provides an overview of the organization of wildlife health surveillance in Switzerland, with a focus on the development, current strategies and the activities of the national program carried out by the Centre for Fish and Wildlife Health (FIWI), University of Bern. This documentation may stimulate on-going discussions on the design and development of national wildlife health surveillance programs in other countries. Investigations into wildlife health in Switzerland date back to the 1950s. The FIWI acts as a national competence center for wildlife diseases on mandate of the Swiss federal authorities. The mandate includes four main activities: disease diagnostics, research, consulting and teaching. In line with this, the FIWI has made continuous efforts to strengthen a national network of field partners and implemented strategies to facilitate long-term and metastudies.

Interprofessionelle Vermittlung praktischer Fertigkeiten durch Peer-Tutoren am Beispiel der Punktion peripherer Venen

1. Hintergrund An der Medizinischen Fakultät der Universität Bern wird seit 2014 ein Kurs in peripherer Venenpunktion (Blutentnahme und Anlage eines peripheren Venenkatheters) zusammen mit der Berner Fachhochschule und dem Bildungszentrum Pflege Bern interprofessionell im Peer Teaching Verfahren unterrichtet. 2. Fragestellung Dabei stellt sich die Frage, ob der interprofessionelle Kurs effektiv in der Vermittlung der Lehrinhalte (Blutentnahme und Anlage eines peripheren Venenkatheters) ist und ob er von den Teilnehmern akzeptiert wird. 3. Methoden Sowohl bei den Teilnehmern, als auch bei den Tutoren sind Studierende aller drei Institutionen vertreten. Der Lernerfolg wird bei den Medizinstudierenden mit einem Posten in einem summativen OSCE (Objektive Structured Clinical Exam) durch ärztliche Dozenten überprüft. Der Posten im OSCE 2015 betraf die Blutentnahme und enthielt 7 Items zum Patientengespräch und 12 Items zur praktischen Durchführung. Die Beurteilung des Kurses durch die Teilnehmer wurde mit offenen Fragen zu Lob und Kritik erhoben. Jede Gruppe von 4-6 Teilnehmern füllte zusammen einen Fragebogen aus. Die Bögen wurden qualitativ nach Prinzipien der Häufigkeitsanalyse ausgewertet. 4. Ergebnisse Im Rahmen des OSCE demonstrierten die Medizinstudierenden, dass sie die Blutentnahme entsprechend den Erwartungen der Experten erlernt hatten. 2015 wurden im Durchschnitt 85% aller Items richtig durchgeführt. Von den Teilnehmern wurde der Kurs sehr positiv evaluiert. 42 von 45 Gruppen gaben einen Bogen ab. Besonders positiv wurde die Kompetenz der Peer Tutoren wahrgenommen (20 von 42 Bögen). 16 von 42 Gruppen lobten die kleine Gruppengrösse und 13 von 42 Gruppen gefiel das didaktische Konzept. 5. Schlussfolgerung Peer Teaching ist auch im interprofessionellen Kontext effektiv und akzeptiert. Der Kurs ist ein Beispiel für einen Grundstein in interprofessioneller Ausbildung auf dem Strukturen zur Weiterentwicklung und Forschung in dem Bereich aufgebaut werden können.

The influence of parent's body mass index on peer selection: An experimental approach using virtual reality

Relatively little is known about the influence of psychosocial factors, such as familial role modeling and social network on the development and maintenance of childhood obesity. We investigated peer se- lection using an immersive virtual reality environment. In a virtual schoolyard, children were confronted with normal weight and overweight avatars either eating or playing. Fifty-seven children aged 7–13 participated. Interpersonal distance to the avatars, child's BMI, self-perception, eating behavior and parental BMI were assessed. Parental BMI was the strongest predictor for the children's minimal distance to the avatars. Specifically, a higher mothers' BMI was associated with greater interpersonal distance and children approached closer to overweight eating avatars. A higher father's BMI was associated with a lower interpersonal distance to the avatars. These children approached normal weight playing and overweight eating avatar peers closest. The importance of parental BMI for the child's social approach/ avoidance behavior can be explained through social modeling mechanisms. Differential effects of pa- ternal and maternal BMI might be due to gender specific beauty ideals. Interventions to promote social interaction with peer groups could foster weight stabilization or weight loss in children.
