Radical activist organizations face the complex task of managing their identity so as to draw political attention but also to appear legitimate and thus gain public support. In this article we develop a picture of the identities of Sea Shepherd Conservation Society (SSCS) members, a group mostly known for their direct action against whaling, via a thematic analysis of material from the SSCS website and interviews with SSCS members. In online commentary, founder Captain Paul Watson establishes several deliberately paradoxical notions of who the Sea Shepherds are. We relate these identity statements to interviews with core activists to examine how they manage the identity conflicts resulting from the group identity, such as being seen as “pirates” and “hard lined vegans.” We found that SSCS positions themselves as a diverse and unstructured organization, yet distinctively passionate and willing to take action where others will not. The implications of this research are discussed in relation to the importance of understanding the constraints and conflicts around political activist identities.  相似文献

Schizophrenia risk alleles are expected to mediate effects on cognitive task performance, and aspects of personality including schizotypy, in nonclinical populations. We investigated how 32 of the best-validated schizophrenia risk alleles, singly and as summed genetic risk, were related to measures of schizotypal personality and measures of two aspects of cognitive performance, verbal skills (vocabulary) and visual-spatial skills (mental rotation), in healthy individuals. Summed genetic risk score was not associated with levels of total schizotypy or its three main subscales. Similarly, genotypic variation at none of the individual risk loci was related to cognitive performance measures, after correction for multiple tests. Higher overall genetic risk score was, however, associated with lower performance on the mental rotation test in males, with a broad set of loci contributing to this effect. These results imply that there is a lack of linear, genetically-based continuity connecting schizotypal cognition with the expression of schizophrenia itself, and indicate that, for males, higher genetic risk of schizophrenia exerts negative effects on visual-spatial skills, as measured by mental rotation.  相似文献

This study examined the relationship between emotional understanding, friendship representation and reciprocity in school-aged children. Two hundred and fifty-one Caucasian 6-year-old children (111 males and 140 females) took part in the study. The Test of Emotion Comprehension (TEC) and the Pictorial Assessment of Interpersonal Relationships (PAIR) were used. Children having a reciprocal friendship and children having a unilateral friendship with a child named as their “best friend” were compared on the emotional understanding task and on their pictorial representations of friendship. Multilevel analyses indicated that friendship status effects were not influenced by classroom-level differences. Results showed that children with reciprocal friendships drew themselves as more similar to and more cohesive with their best friends, and they showed better understanding of emotions, than children having a unilateral friendship. Finally, the implications of these findings for theoretical and empirical research development on friendship are discussed.  相似文献

This study investigated the self-image and psychological well-being in 67 children and adolescents age 10–16 years with severe reading difficulties and/or dyslexia. The participants were assessed with Beck Youth Inventory regarding symptoms of depression, anxiety, and negative self-image. The results showed that the participants do not depict negative self-image and showed few symptoms of depression or anxiety at group level in comparison to a norm group. These results could be seen as contradictory to previous research. A questionnaire regarding self-efficacy was also distributed and showed that the participants had low self-knowledge about their reading impairments. The results were interpreted as a possible increase in knowledge among teachers and subsequent change in pedagogical strategies. In addition, technological advances may have improved the academic situation for dyslexic children. This study was a partial study in a larger project that aimed to evaluate the efficiency of assistive technologies for dyslexic children.  相似文献

The purpose of this study was to longitudinally investigate PTSD and depression between Reserve, National Guard, and active duty continuously and dichotomously. The study consisted of Millennium Cohort Study participants and used self-reported symptoms. Repeated measures modeling assessed PTSD and depression continuously and dichotomously over time. A subanalysis among only recently deployed personnel was conducted. Of the 52,653 participants for the PTSD analysis, the adjusted PCL-C means were 34.6 for Reservists, 34.4 for National Guardsmen, and 34.7 for active duty members, respectively. Of the 53,073 participants for depression analysis, the adjusted PHQ-9 means were 6.8, 6.7, and 7.2, respectively. In dichotomous models, Reservists and National Guardsmen did not have a higher risk of PTSD or depression compared with active duty members. Among deployers, Reservists and National Guardsmen had higher odds (odds ratio = 1.16, 95% confidence limit [CL] [1.01, 1.34] and OR = 1.19, 95% CL [1.04, 1.36], respectively) of screening positive for PTSD, but not depression. Although Reserve and National Guard deployers had modestly increased odds of PTSD compared with active duty members, overall there were minimal differences in the risk and symptom scores of PTSD and depression between service components.  相似文献

ABSTRACT

Natural history museums open their doors to millions of family visitors each year and are considered to have a valuable role to play in engaging these families with science. Yet little is known about whether or in what way families perceive such institutions to be connected with science. The current study set out to explore such perceptions via interviews with family visitors to a large natural history museum. Analyses reflected that families’ perceptions of the museum and of their own engagement with science were intertwined with their definitions and impressions of science. For these families, perceptions of the museum as fun, interesting, and educational at times counteracted impressions of it as a science-y institution. Moreover, some families also did not consider natural history to count as science, which further contributed to a reluctance to categorize the museum as science-y. Although such perceptions may challenge how natural history museums would like to portray themselves, they also represent an opportunity to broaden visitors’ definitions and images of science.  相似文献

This study sought to identify factors associated with attrition for 197 individuals who participated in a state-sponsored rural domestic violence treatment program. Bivariate analyses identified 10 factors associated with program attrition. Logistic regression identified three of these (employment status, psychiatric disorder type, and probation status) as significant predictors of attrition. This three-factor model predicted 78% of all outcomes and 43% and 92% of dropouts and completers, respectively. The data suggest that batterer characteristics, particularly batterer psychopathology, unemployment, and criminal history, are more influential determinants of attrition than systemic and programmatic factors. These findings are discussed with respect to their congruence with the literature and their implications for policy, practice, and future research.  相似文献

Faces of one's own race and of other races are thought to be located in different regions of face space (Valentine, 1991 Valentine, T. 1991. A unified account of the effects of distinctiveness, inversion, and race in face recognition. Quarterly Journal of Experimental Psychology, 43A: 161204. [Taylor & Francis Online] [Google Scholar]). Here we investigated whether faces of different races (Caucasian and Chinese faces) have dissociable neural coding and distinct norms. We used adaptation techniques to alter perceptions of normality (aftereffects) for faces. Caucasian and Chinese participants adapted to distorted faces of one race (e.g., Chinese contracted faces—Experiment 1), or oppositely distorted faces of both races (e.g., Chinese contracted and Caucasian expanded faces—Experiment 2). We then tested for aftereffects in Chinese and Caucasian test faces. In Experiment 1 aftereffects were reduced when a change in race between the adapt faces and test faces occurred. In Experiment 2 aftereffects occurred in opposite directions for the two races. These results demonstrate that dissociable neural populations code faces of different races and suggest the existence of race-specific face norms.  相似文献

Niche construction is the modification of components of the environment through an organism's activities. Humans modify their environments mainly through ontogenetic and cultural processes, and it is this reliance on learning, plasticity and culture that lends human niche construction a special potency. In this paper we aim to facilitate discussion between researchers interested in niche construction and those interested in human cognitive development by highlighting some of the related processes. We discuss the transmission of culturally relevant information, how the human mind is a symbol‐generating and artefact‐devising system, and how these processes are bi‐directional, with infants and children both being directed, and directing, their own development. We reflect on these in the light of four approaches: natural pedagogy, activity theory, distributed cognition and situated learning. Throughout, we highlight pertinent examples in non‐humans that parallel or further explicate the processes discussed. Finally we offer three future directions; two involving the use of new techniques in the realms of neuroscience and modelling, and the third suggesting exploration of changes in the effects of niche construction across the lifespan.  相似文献
