A recent methodological advance in legislative roll-call analysis is especially relevant to the study of legislative behavior outside the setting of the United States Congress. We argue that Poole's (2000) optimal classification method for roll-call analysis is preferable to parametric methods for studying many legislatures. This is because the nature of party discipline, near-perfect spatial voting, and parliamentary institutions that provides incentives for strategic behavior lead to severe violations of the error assumptions underlying parametric methods. The robustness of the nonparametric method to the stochastic nature of the data makes it an ideal candidate for studying strategic behavior in legislatures. We illustrate these points with an analysis of data from the French Fourth Republic (1946–1958) .  相似文献

Quantifying the strength of gunshot residue (GSR) evidence requires scientific knowledge about the number of particles expected to be found on individuals who were or were not involved in a shooting. However, controlled experiments demand expensive resources in terms of microscope time and labor, which restricts the data of most studies to only a small group of individuals. We suggest a novel method that exploits data collected routinely on suspects during the daily work of forensic laboratories. These observational data relate to both persons who were involved in a shooting and innocent individuals. We suggest a mixture approach with different models for the number of gunshot residue particles in each group and develop an iterative algorithm to estimate the probabilities of observing the evidence under the defense proposition that the suspect is innocent and under the prosecution assumption that he is not. The method is applied to data of more than 500 suspects collected by the Israel National Police Division of Identification and Forensic Science. The analysis shows that the probability of finding three or more GSR particles on the hands of innocent suspects is very small, less than 1.5 in 1000 cases. Our new method enables researchers to use data on real cases, possibly supplemented by experimental data, in order to estimate the probabilities of a given GSR finding under the defense and prosecution propositions.  相似文献

Childbirth has been positioned as a life changing event that has profound long-term psychological effects upon women. This paper adopts a community psychology approach to explore the role that the Positive Birth Movement (PBM) may have in tackling negative birth experiences by supporting women before and after birth. Six women who all regularly attend UK-based PBM meetings and had given birth to at least one child participated in one to one semi-structured interviews designed to explore the support they received before, during and after their birth, as well as their experiences with the PBM. A Foucauldian inspired discourse analysis explores themes relating to the lack of support and information provided by the NHS and the function of the PBM as a transformative community space which offers social support and information. Within these themes a focus on neoliberalism, choice and the woman’s position as an active consumer of health care is critically discussed. It is argued that the PBM has the potential to prepare women for positive birth experiences but more attention needs to be paid to the wider contexts that limit women’s ability to make ‘free’ choice.  相似文献

Callous-unemotional (CU) traits (i.e., lack of empathy/guilt, uncaring attitudes) are believed to be a developmental antecedent to adult psychopathy and identify antisocial youth at risk for severe and persistent aggression. The psychosocial histories of antisocial and aggressive individuals with psychopathic traits are characterized by abusive or unaffectionate parenting; however, there is a gap in the literature regarding the unique impact of these factors on adolescent offenders. The purpose of the present study was to examine the contribution of maternal warmth and affection (i.e., care) to dimensions of CU traits and aggression, after accounting for the influence of various types of childhood maltreatment. We investigated this aim in a sample of 227 urban male adolescent offenders housed in residential facilities. Results indicated that low maternal care was significantly associated with greater total CU traits and uncaring and callousness dimensions, even after controlling for the effects of various types of childhood abuse and neglect. Furthermore, there was a significant interaction between CU traits and care, such that aggression was highest among youths scoring high on CU traits who were exposed to low levels of maternal care. These findings draw attention to the importance of maternal bonding to CU traits and related aggressive behaviors among antisocial youth.  相似文献

Minimal attention has been focused on difficulties for youth in residential care regarding building healthy dating relationships, despite the significant risks to this group of adolescents. This study provided a unique opportunity to conduct focus groups with youth in residential care on issues surrounding dating relationships. The majority of youth feedback centered on the themes of desiring support developing relationship boundaries, establishing trust in relationships, understanding the consequences of sexual activity, and having real world examples regarding dating relationships. The data were examined for differences between the genders and recommendations for next steps provided.  相似文献

Abstract: Over the course of this article, the author argues that ethics and the erotic are interrelated. The author also contends that the way subjectivities are constructed has a strong impact on the development of the ethical and the erotic character of these same subjectivities. Against this backdrop, the author postulates that envisioning or creating oneself as a grotesque subject promises to facilitate one's own development into a moral and erotic human being by triggering a process of inner estrangement that enables one to recognize the otherness within oneself. This analysis is based mainly on Mikhail Bakhtin's grotesque as presented in his Rabelais and His World (1965). This self-introspection serves as the basis for an ethical eroticism through which one shall transform oneself into a fully fledged moral and sensual subject. In formulating this argument, the author draws on Simone de Beauvoir's own attempt to link the erotic to the ethical. As will be seen, the same principle that stands at the heart of a phenomenological ethics also steers the author's phenomenological conception of the erotic. The principle in question is carnal intersubjectivity-bodies that penetrate one another and merge, yet never lose themselves in the other's carnality. Put differently, they remain non-objectified subjects. The grotesque subject is presented as a figuration that helps shed light on the way the subject has been conceived by, above all, phenomenological and postmodern theorists. The author then explores some of the ethical ramifications of this conceptualization. Drawing on these insights, the author fashions an ethical eroticism that derives from a grotesque subjectivity.  相似文献

Self-reported depressive experiences are common among university students. However, most studies assessing depression in university students are cross-sectional, limiting our understanding of when in the academic year risk for depression is greatest and when interventions may be most needed. We examined within-person change in depressive symptoms from September to April. Study 1 (N?=?198; 57% female; 72% white; Mage?=?18.4): Depressive symptoms rose from September, peaked in December, and fell across the second semester. The rise in depressive symptoms was associated with higher perceived stress in December. Study 2 (N?=?267; 78.7% female; 67.87% white; Mage?=?21.25): Depressive symptoms peaked in December and covaried within persons with perceived stress and academic demands. The results have implications for understanding when and for whom there is increased risk for depressive experiences among university students.  相似文献
