In recent years, voluntary associations and political organizations have increasingly relied on Internet-based mobilization campaigns, replacing traditional forms of face-to-face recruitment and mobilization. Within the literature, one can observe an intensive debate about the possible consequences of this transition. Most importantly, the question is whether political mobilization through the Internet is just as effective as mobilization in a face-to-face setting. In this article, we report on a mobilization experiment using both traditional (face-to-face) and modern (Web site) incentives for mobilization. The experiment was conducted among undergraduate students in Belgium and Canada and included a test of medium-term mobilization effects. Results suggest that the Internet is successful in transferring knowledge and raising issue salience among respondents, but neither experimental manipulation led to significant behavioral changes. We do not find any indication that among this experimental sample Internet-based mobilization would be less effective than traditional face-to-face forms of mobilization.  相似文献

Many researchers have been working in Spain to document the communal graves of those assassinated during the Spanish Civil War. This article shows the results obtained with two low‐cost photogrammetric techniques for the basic documentation of forensic studies. These low‐cost techniques are based on single‐image rectification and the correction of the original photo displacement due to the projection and perspective distortions introduced by the lens of the camera. The capability of image rectification is tested in an excavation in the village of Loma de Montija (Burgos, Spain). The results of both techniques are compared with the more accurate data obtained from a laser scanner system RIEGL LMS‐Z390i to evaluate the error in the lengths. The first technique uses a camera situated on a triangle‐shaped pole at a height of 5 m and the second positions the camera over the grave using a linearly actuated device. The first technique shows measurement errors less than 6%, whereas the second shows greater errors (between 8% and 14%) owing to the positioning of the carbon‐fiber cross on an uneven surface.  相似文献

Weight is often one of the few recoverable data when analyzing human cremains but references are still rare, especially for European populations. Mean weights for skeletal remains were thus documented for Portuguese modern cremations of both recently deceased individuals and dry skeletons, and the effect of age, sex, and the intensity of combustion was investigated using both multivariate and univariate statistics. The cremains from fresh cadavers were significantly heavier than the ones from dry skeletons regardless of sex and age cohort (p < 0.001 to p = 0.003). As expected, males were heavier than females and age had a powerful effect in female skeletal weight. The effect of the intensity of combustion in cremains weight was unclear. These weight references may, in some cases, help estimating the minimum number of individuals, the completeness of the skeletal assemblage, and the sex of an unknown individual.  相似文献

We report the case of a man who died twelve hours after ingesting powdered iboga root, commonly taken for its stimulant and hallucinogenic properties. Ibogaine and ibogamine were quantified in the powder ingested and the victim's body fluids by GC‐MS/MS after liquid–liquid extraction (Toxi‐tubes A®). The concentrations of ibogaine measured in the blood samples taken at the scene and in the peripheral blood, urine, and gastric fluid samples taken during the autopsy were 0.65, 1.27, 1.7, and 53.5 μg/mL, while the iboga content in the powder was 7.2%. Moreover, systematic toxicological analyses of biological samples showed the presence of diazepam and methadone in therapeutic concentrations. Death was attributed to the ingestion of a substantial quantity of iboga in the context of simultaneous methadone and diazepam consumption.  相似文献

The aim of this study was to examine the relationship between intimate partner violence (IPV) and personality disorder symptoms controlling for depressive state. Victims of IPV (n?=?176) and non-abused women (n?=?193) completed the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ), Index of Spouse Abuse (ISA), and Beck Depression Inventory-II (BDI-II). IPV victims scored higher than non-abused women on Intimacy Problems, and scored lower on Rejection traits, after adjustment for depressive symptoms. Severity of the IPV was related to Cognitive Distortion, Suspiciousness, Restricted Expression, and Intimacy Problems, and the length of the IPV was negatively associated with Rejection. The current study suggests only modest differences in personality traits between IPV and non-abused women. The DAPP-BQ traits associated with severity of IPV, in a dose-response manner, would partially reflect the symptoms of complex post-traumatic stress disorder (CPTSD), although this possibility deserves further study.  相似文献

This paper focuses on the nexus between nascent entrepreneurship (NE) and inventive activity. It questions how NE affects inventive activity (including innovation and patenting) while analyzing the views and predictions that have used patenting as an indicator of entrepreneurial behavior. Using data on German researchers and controlling for their personal, professional and institutional attributes, the findings show that NE increases both patenting and innovation. Implications for technology policy are discussed.  相似文献

Previous studies of the electoral consequences of corruption in Spanish local elections (Jiménez Revista de Investigaciones Políticas y Sociológicas, 6(2):43–76, 2007; Fernández-Vázquez and Rivero 2011, Consecuencias electorales de la corrupción, 20032007. Estudios de Progreso, Fundación Alternativas; Costas et al. European Journal of Political Economy: 28(4):469-484, 2012) have found that voters do not necessarily punish corrupt mayors. As has been pointed out in the comparative literature, the average loss of electoral support by corrupt incumbents is small and does not prevent their reelection most of the times (Jiménez and Caínzos 2006, How far and why do corruption scandals cost votes? In Garrard, J. and Newell, J. (eds.) Scandals in past and contemporary politics. Manchester: Manchester University Press). What remains unsolved, however, is the remarkable variability in this pattern. This article explores some of the micro-level variables that may mediate the effect of corruption scandal on the votes. We focus on three factors: ideological closeness to the incumbent party, political sophistication, and employment status. Our results provide only partial support for our hypotheses, suggesting that the effects of corruption are much more complex than what may seem at first sight.  相似文献
