Interactive educational DVD on hoof protection, horseshoeing and diseases of the hoof

Good cooperation between farrier, veterinarian and horse owner is an important prerequisite for optimal support of the horse with regards to shoeing and hoof health. The introduction of a joint educational aid aims to improve the level of education of both veterinarians and farriers. The interactive, multimedia approach represents an innovative new dimension in instruction techniques, predominantly provided through images and videos. The contents of the new teaching aid will focus on detailed anatomy of the foot and distal limb, as well as currently accepted shoeing practices and techniques and pathologic conditions of the hoof and foot.

Reputation Formation and the Evolution of Cooperation in Anonymous Online Markets

Theoretical propositions stressing the importance of trust, reciprocity, and reputation for cooperation in social exchange relations are deeply rooted in classical sociological thought. Today’s online markets provide a unique opportunity to test these theories using unobtrusive data. Our study investigates the mechanisms promoting cooperation in an online-auction market where most transactions can be conceived as one-time-only exchanges. We first give a systematic account of the theoretical arguments explaining the process of cooperative transactions. Then, using a large dataset comprising 14,627 mobile phone auctions and 339,517 DVD auctions, we test key hypotheses about the effects of traders’ reputations on auction outcomes and traders’ motives for leaving feedback. Our statistical analyses show that sellers with better reputations have higher sales and obtain higher prices. Furthermore, we observe a high rate of participation in the feedback system, which is largely consistent with strong reciprocity—a predisposition to unconditionally reward (or punish) one’s interaction partner’s cooperation (or defection)—and altruism—a predisposition to increase one’s own utility by elevating an interaction partner’s utility. Our study demonstrates how strong reciprocity and altruism can mitigate the free-rider problem in the feedback system to create reputational incentives for mutually beneficial online trade.

Internetbasierte Psychotherapie

In den letzten Jahren wurde ein breites Spektrum an internet- bzw. technikbasierten Interventionen bei psychischen Problemen und Erkrankungen entwickelt. Angebote reichen von internetbasierten und DVD-vermittelten Selbsthilfeprogrammen zu E-Mail-Therapien, von Prävention über Beratung und Behandlung zu Nachsorge- und Rückfallpräventionsprogrammen, und von Interventionen, die computervermittelte Teile in hauptsächlich Face-to-Face durchgeführte Interventionen integrieren bis hin zu vollständig via Internet durchgeführte Therapien. In diesem Workshop werden verschiedene Ansätze und empirische Befunde erläutert. Anhand konkreter Beispiele werden Vor- und Nachteile, sowie Qualitätsmerkmale entsprechender Angebote diskutiert.

Analytical, physiologic, and clinical validation of a radioimmunoassay for measurement of procollagen type III amino terminal propeptide in serum and bronchoalveolar lavage fluid obtained from dogs.

OBJECTIVE To validate a radioimmunoassay for measurement of procollagen type III amino terminal propeptide (PIIINP) concentrations in canine serum and bronchoalveolar lavage fluid (BALF) and investigate the effects of physiologic and pathologic conditions on PIIINP concentrations. SAMPLE POPULATION Sera from healthy adult (n = 70) and growing dogs (20) and dogs with chronic renal failure (CRF; 10), cardiomyopathy (CMP; 12), or degenerative valve disease (DVD; 26); and sera and BALF from dogs with chronic bronchopneumopathy (CBP; 15) and healthy control dogs (10 growing and 9 adult dogs). PROCEDURE A radioimmunoassay was validated, and a reference range for serum PIIINP (S-PIIINP) concentration was established. Effects of growth, age, sex, weight, CRF, and heart failure on S-PIIINP concentration were analyzed. In CBP-affected dogs, S-PIIINP and BALF-PIIINP concentrations were evaluated. RESULTS The radioimmunoassay had good sensitivity, linearity, precision, and reproducibility and reasonable accuracy for measurement of S-PIIINP and BALF-PIIINP concentrations. The S-PIIINP concentration reference range in adult dogs was 8.86 to 11.48 mug/L. Serum PIIINP concentration correlated with weight and age. Growing dogs had significantly higher S-PIIINP concentrations than adults, but concentrations in CRF-, CMP-, DVD-, or CBP-affected dogs were not significantly different from control values. Mean BALF-PIIINP concentration was significantly higher in CBP-affected dogs than in healthy adults. CONCLUSIONS AND CLINICAL RELEVANCE In dogs, renal or cardiac disease or CBP did not significantly affect S-PIIINP concentration; dogs with CBP had high BALF-PIIINP concentrations. Data suggest that the use of PIIINP as a marker of pathologic fibrosis might be limited in growing dogs.

Antike Theater und Masken online – Onlinedokumentation

Antike Theater und Masken online enthält etwa 800 Farbfotografien von antiken Theatern und 600 von Masken aus den Ländern rund um das Mittelmeer, aus Westeuropa und aus zahlreichen Museen. Die Sammlung des Basler Theaterhistorikers Karl Gotthilf Kachler (1906-2000) entstand zwischen dem Ende der 1950er-Jahre und dem Beginn der 1980er-Jahre auf zahlreichen Forschungsreisen. Er übergab 1999 die ursprünglich über 5’000 Diapositive dem Institut für Theaterwissenschaft der Universität Bern zur Bearbeitung. Im Jahr 2003 erschien im Chronos Verlag Zürich der Katalog Antike Theater und Masken mit einer beiliegenden DVD, die eine repräsentative Auswahl von 1’400 am ITW durch Sara Aebi und Regula Brunner thematisch kontextualisierten und kommentierten Fotografien zeigte. Die Herausgabe von Antike Theater und Masken online erfolgt durch Andreas Kotte, Direktor des ITW Bern und Projektleiter.
