It is perfectly obvious that in any decent occupation…there are only two ways…of succeeding. One is by doing very good work, the other is by cheating.  相似文献

In this article, I focus on Chapters 4 and 5 of On the People’s Terms, chapters that deal with democratic influence and control. I take an applied political science approach to how Pettit’s republic might be practically achieved by exploring the under-appreciated capacity of elections to mobilise the resistance-prone, contestatory public upon which his republicanism depends. Whereas Pettit tends to focus on public contestation between elections and only demands that the public has the opportunity to vote when elections are held, I argue that they should be given a more prominent role within his republic and further, that access to voting is not enough: rather, citizens should actually vote. In order to ensure that participation is socially inclusive and that the public’s attempts at influence are ‘individualised’, ‘unconditioned’ and ‘efficacious’ in the manner Pettit desires, I suggest that compulsory voting should be a major pillar of his republicanism.  相似文献

We tested the independent utility of β-amyloid precursor protein (β-APP) immunohistochemical staining as evidence of brain trauma in the deaths of young children. Blinded reviewers retrospectively reviewed immunostained brain tissues from homicidal deaths, age-matched control cases without evidence of trauma, as well as cases of sudden infant death syndrome (SIDS). The reviewers correctly identified five of the seven cases with documented inflicted head trauma. However, one of seven age-matched control cases and one of 10 SIDS/sudden unexplained death in infancy (SUDI) cases demonstrated staining patterns similar to those seen in cases of inflicted trauma. We discuss these cases and the circumstances surrounding them with the intent to explain the difficulties associated with immunohistological interpretation of axonal injury. Although the utility of β-APP is quite powerful if not confounded by global hypoxic-ischemic injury, ultimately, β-APP studies should be only one piece of information in the determination of cause and manner of death.  相似文献

Hunting many types of wild game is an avidly pursued outdoor activity that attracts all ages and both genders at various times of the year. Deer hunting is a popular sport in many regions of North America. A variety of weapons are used in the hunting, trapping, and killing of game. As a variety of different modalities are used, myriad types of injuries unique to the type of hunting can occur. Most deer hunting-related fatalities identified at the Office of the Chief Medical Examiner in Kentucky are accidental firearm injuries. Less commonly encountered are fatalities resulting from elevation of the hunter in a tree stand, often associated with poor design or construction of the perch. We present 2 tree stand-related deaths. One victim died of positional asphyxia due to reverse suspension from a hunting tree stand. The second victim died of multiple blunt force injuries sustained in a 20-foot fall from a tree stand. We summarize the features of morbidity and mortality related to deer hunting based on investigations by the Office of the Chief Medical Examiner.  相似文献

Adolescents may engage in risk behaviors that jeopardize their futures. Although adolescent risk-taking has long been attributed to faulty decision making, surprisingly little research has directly examined this link. This study examined the role of deliberative decision making (the tendency to consider options and consequences before making a decision) and social contextual variables (parenting and friend influences) in alcohol and drug use, risky sex, and delinquency. Participants were 7,748 adolescents (50% female) in grades 7–11 from the Add Health dataset (M age = 14.87, SD = 1.54). Hierarchical regression analyses revealed that deliberative decision making and contextual variables were associated with risk behavior concurrently and 1 year later. Furthermore, deliberative decision making interacted with social contextual variables in some models, indicating that deliberative decision making may be especially important in certain contexts. These findings suggest that both cognitive and social factors need to be considered to explain adolescents’ decisions to engage in risk behavior.  相似文献

Emotional and cognitive changes that occur during adolescence set the stage for the development of adaptive or maladaptive beliefs about emotions. Although research suggests that parents’ behaviors and beliefs about emotions relate to children’s emotional abilities, few studies have looked at parental socialization of children’s emotions, particularly in families with depressed adolescents. The present study examined associations between parent and adolescent meta-emotion philosophies (MEP), defined as thoughts, reactions, and feelings about their own emotions. Additionally, adolescent depressive status was tested as a moderator of relationships between parents’ and adolescents’ MEP. One hundred and 52 adolescents, aged 14–18 (65.8% female), and their parents (148 mothers, 106 fathers) participated in a study on emotion socialization in families of depressed and healthy adolescents. Depressed adolescents (n = 75) and matched healthy adolescents (n = 77) were recruited based on research criteria for mental health status. The sample was largely Caucasian (82%) and of middle socioeconomic class status. Results indicated that mothers’ and fathers’ MEP about their children’s emotions were associated with adolescents’ MEP, although parents’ MEP about their own emotions was unrelated to adolescents’ MEP. Fathers’ MEP about children’s emotions made unique contributions to adolescents’ MEP across both adolescent groups. Adolescents’ depressive status moderated the relationship between mothers’ and adolescents’ MEP such that mothers’ MEP was particularly relevant for depressed adolescents. The continued influence of parents in the emotional lives of adolescents is discussed as well as differences in emotion socialization in families with depressed and healthy adolescents.  相似文献

The terrorist attacks on the World Trade Center and the Pentagon on September 11, 2001, compelled most Americans to imagine the unimaginable. Increased interest was focused on lessons learned, specifically if local law enforcement agencies had made appropriate organizational changes to manage potential terrorism events. The purpose of this study was to assess perceptions of law enforcement officers in the state of Michigan regarding organizational changes post 9/11. A total of 247 law enforcement officers participated in the study by completing three instruments, the Police Unit Assessment of Terrorism (PAT) Scale, Domestic Unit Assessment of Terrorism (DAT) Scale, and a short demographic survey. The officers who perceived their work load had increased since 9/11 were more likely to have more positive perceptions on both the PAT and DAT.  相似文献
