Laaksonen T Sariola H Johansson A Jern P Varjonen M von der Pahlen B Sandnabba NK Santtila P 《Child abuse & neglect》2011,35(7):480-490
Objective
We examined (1) the prevalence of childhood sexual abuse (CSA) experiences as a function of cohort and gender, (2) the prevalence of factors associated with CSA as a function of cohort and whether the association of these factors with CSA remained the same irrespective of cohort, and (3) whether any cohort differences could be explainable by cohort differences in reporting bias.Method
We used the responses of 4,561 men (M = 29, SD = 7 years) and 8,361 female (M = 29, SD = 7 years) Finnish participants who responded to the Childhood Trauma Questionnaire-Short Form as well as questions regarding family structure.Results
The prevalence of CSA experiences varied between 0.7-4.6% for men and 1.8-7.5% for women depending on the item. Younger cohorts reported less CSA as well as less of the risk factors (physical neglect and abuse, emotional neglect and abuse, parental substances abuse, not growing up with both biological parents) that were positively associated with the likelihood of CSA. The effects of these risk factors did not vary as a function of the cohort. Also, the declining trend was not explainable by social desirability being higher in the younger cohorts.Conclusions
The results suggest that there is a real decline in the prevalence of CSA and it is associated with a simultaneous decline in factors associated with CSA. 相似文献15.
We test the hypothesis that scientific collaboration is associated with increased publication productivity. We differentiate our approach from other studies by (a) incorporating professional networks in the productivity model, (b) casting productivity and collaboration as distinct phenomena, and (c) examining these phenomena in the context of resource-constrained research institutions in a developing country. We use survey data and employ negative binomial regression models. Results indicate that publication productivity is significantly linked to professional network factors, but there is no evidence of any association with scientific collaboration. We observe that most scientists collaborate in research projects despite coordination difficulties, and without any measurable impact on their productivity. Our interviews reveal that a possible answer to this puzzle appears to be rooted in a practice that views collaborative research projects not mainly as a means to producing knowledge and gaining recognition, but for acquiring professional opportunities and extrinsic rewards. Our findings suggest a new way of modeling publication productivity, with implications for science and innovation policy in both the developed and the developing world. 相似文献

Foreign firms patent in emerging economies with weak appropriability regimes at an increasing rate. This phenomenon constitutes a paradox since in such a setting foreign firms should have weak incentives to patent. In an attempt to resolve this paradox, we conducted an inductive analysis of 11 foreign firms that patent in such a setting, using the case of China as our empirical context. We identify four archetypes of foreign firms and three key antecedents the interaction of which determines which archetype a firm can be subsumed under.Our study complements the developed-economy focus of the extant appropriation literature by adding an international perspective. We extend previous econometric studies by identifying salient factors on the firm level that determine the extent to which a foreign firm patents in emerging economies with a weak appropriability regime, highlighting that the extent of a firm's motivation to maintain its freedom to operate can supersede imitability concerns. We also comment on the practical implications of these contributions for managers of foreign firms. Highlighting a structural conflict of interest between foreign firms from developed economies and the development goals of an emerging economy, we point to the generalizability of our results to a wide range of other emerging economies worldwide. 相似文献

A quality of interrelating: describing a form of meaningful experience on a wilderness river journey
Marcus Morse 《Journal of Adventure Education & Outdoor Learning》2013,13(1):42-55
In this paper I identify the components of ‘meaningful experiences’ for participants on a wilderness river rafting journey. The research is phenomenologically informed, and includes interviews, journals, observations and follow-up emails from 32 participants on eight Franklin River (Tasmania) 10-day trips. It elicits individual perceptions of meaningful experiences and combines recollections to reveal the commonalities within those experiences. The research identifies two key recurrent ‘streams of experience’ that provide meaning. The two recurrent streams of experience involved, firstly, a feeling of humility and, secondly, being alive to the present. In this paper I focus on the stream of experience surrounding a feeling of humility, highlighting the qualities of the ways in which participants interrelated with their surrounding environments and the structure of such experiences. Additionally, I consider some unique elements of the wilderness river journey that contributed to the experiences that participants valued as meaningful. 相似文献

Historical perspective taking: A standardized measure for an aspect of students' historical thinking
Researchers widely agree that learning history should involve more than learning historical facts and should include competencies of historical thinking. Various models of historical thinking view students' competency to take historical perspectives as a standard in history education. In this study we introduce a standardized measure for historical perspective taking (HPT) consisting of a short scenario set in the German Weimar Republic. We assessed students' HPT by using rating scales; our data were obtained in grammar schools from 170 German 10th graders. Latent class analyses identified three types of students with similar profiles of HPT. One was present-oriented and two showed more or less contextualized historical thinking. Students' history grades were connected to their HPT competency. We discuss limitations of the study and argue for further research on measures assessing students' historical thinking. 相似文献
