OBJECTIVE: To investigate the prevalence of discontinuation and nonpublication of surgical versus medical randomized controlled trials (RCTs) and to explore risk factors for discontinuation and nonpublication of surgical RCTs. BACKGROUND: Trial discontinuation has significant scientific, ethical, and economic implications. To date, the prevalence of discontinuation of surgical RCTs is unknown. METHODS: All RCT protocols approved between 2000 and 2003 by 6 ethics committees in Canada, Germany, and Switzerland were screened. Baseline characteristics were collected and, if published, full reports retrieved. Risk factors for early discontinuation for slow recruitment and nonpublication were explored using multivariable logistic regression analyses. RESULTS: In total, 863 RCT protocols involving adult patients were identified, 127 in surgery (15%) and 736 in medicine (85%). Surgical trials were discontinued for any reason more often than medical trials [43% vs 27%, risk difference 16% (95% confidence interval [CI]: 5%-26%); P = 0.001] and more often discontinued for slow recruitment [18% vs 11%, risk difference 8% (95% CI: 0.1%-16%); P = 0.020]. The percentage of trials not published as full journal article was similar in surgical and medical trials (44% vs 40%, risk difference 4% (95% CI: -5% to 14%); P = 0.373). Discontinuation of surgical trials was a strong risk factor for nonpublication (odds ratio = 4.18, 95% CI: 1.45-12.06; P = 0.008). CONCLUSIONS: Discontinuation and nonpublication rates were substantial in surgical RCTs and trial discontinuation was strongly associated with nonpublication. These findings need to be taken into account when interpreting surgical literature. Surgical trialists should consider feasibility studies before embarking on full-scale trials.

The investigation of the consequences of new technologies has a long standing tradition within economics. Particularly, labor economists are wondering how the introduction of new technologies, e.g. Personal Computers, have shaped labor markets. Former research has concentrated on the question of whether on-the-job use of PCs creates a wage bonus for employees. In this paper, we investigate whether the use of PCs increases employees’ probability of an upward shift in their employment status and whether it reduces the risk of involuntary labor market exits. We do so by applying event history analysis to the Swiss Labor Market Survey, a random sample of 3028 respondents, and by analyzing a Panel sub-sample of 650 respondents conducted recently in Switzerland. Our results show that on-the-job use of PCs was beneficial for employees in the past by increasing their probability of an upward shift by approximately 50%. The analysis also suggests that PC use reduces the risk and duration of unemployment. However, these latter results fail to reach statistical significance.

Indigenous media as a phenomenon cannot be reduced to a reaction to western hegemony and colonial legacies, but is often rooted in the context of resistance, empowerment, self-determination and the reclaiming of symbolic representation. Therefore I would like to reflect on different cases of indigenous film and participatory video work in an attempt to highlight the multiple dynamics that arise due to the desideratum of self-representation and to finally locate us as anthropologists in that context.

Der Erste Weltkrieg war – das hatten deutsche Militärs vor 1914 schon erwartet – von Beginn weg ein globaler Krieg. Grossbritannien und Frankreich setzten nämlich schon ab den ersten Monaten Truppen aus anderen Teilen der Welt auch in Europa ein. Dazu gehörten auch Soldaten aus Australien, Neuseeland und Indien. Teile letzterer kämpften schon im Herbst 1914 in Nordfrankreich und Belgien mit, andere waren ab April 1915 auf der türkischen Halbinsel Gallipoli aktiv. Dort kamen erstmals auch australische und neuseeländische Soldaten und Offiziere zum Einsatz. Ab 1916 wurden diese dann zu grossen Teilen an der Westfront verlegt, während die meisten indischen Verbände ab diesem Zeitpunkt im Nahen Osten zum Einsatz kamen. Der vorliegende Beitrag versucht auf der Grundlage von Selbstzeugnissen und Fremdbeschreibungen an exemplarischen Beispielen aufzuzeigen, wie es dazu kam, dass Soldaten und Offiziere aus Australien, Neuseeland und Indien in Gallipoli und an der Westfront zum Einsatz kamen, welches ihre Motivationen und Ziele waren, inwiefern sie sich dabei als Minderheit verstanden und welche Vorstellungen sie mit Blick auf ihre Rolle bzw. die Rolle ihrer Heimat nach dem Krieg hatten. Zum Schluss soll noch ein kurzer Blick auf die Bedeutsamkeit dieser Soldaten im Rahmen der nationalen und regionalen Erinnerungskultur in den drei Ländern geworfen werden.
