The higher prevalence of insomnia in women has been attributed to biological factors, which are less likely than cognitive and behavioural factors to play a role in perpetuating insomnia. Gender differences in perpetuating factors have not been extensively examined. This study compared men’s and women’s self-reports of factors that perpetuate insomnia; experience of symptoms, perceived severity and impact on daytime functioning; and use of strategies to manage insomnia. Data were collected at baseline, using reliable and valid measures, in a project that evaluated behavioural therapies for insomnia. The sample (N = 739) consisted of women (62.4%) and men (37.6%). Gender differences were found in: (1) perpetuating factors: men took more naps and held more unhelpful beliefs about insomnia, whereas women experienced higher pre-sleep arousal; (2) perception of insomnia severity: higher among women; (3) perceived impact of insomnia: higher fatigue among women; and (4) use of strategies (higher in women) to manage insomnia. Gender differences were of a small size but could be associated with women’s stress, expression of somatic symptoms, and interest in maintaining their own health to meet multiple role demands.  相似文献

This research note argues that the “lone wolf” typology should be fundamentally reconsidered. Based on a three-year empirical research project, two key points are made to support this argument. First, the authors found that ties to online and offline radical milieus are critical to lone actors' adoption and maintenance of both the motive and capability to commit acts of terrorism. Second, in terms of pre-attack behaviors, the majority of lone actors are not the stealthy and highly capable terrorists the “lone wolf” moniker alludes to. These findings not only urge a reconsideration of the utility of the lone-wolf concept, they are also particularly relevant for counterterrorism professionals, whose conceptions of this threat may have closed off avenues for detection and interdiction that do, in fact, exist.  相似文献

Abstract

Scalability can be understood as the ability to expand without changing. Yet, expanding an intervention to a global scale, we suggest, is a significant and difficult accomplishment. In this paper we propose to explore the kind of evidential exigencies that this accomplishment involves. To do so, we focus on the field of global health and examine how child immunization against the pneumococcus bacterium has been scaled up in low-income countries. The paper first attends to initial epidemiological scrutiny that revealed the existence of a large-scale public health problem and the possibility of an expandable solution (vaccination). It then describes the set-up of a funding arrangement using overseas aid to purchase vaccine doses manufactured by pharmaceutical companies, before paying attention to various frictions that affect the widespread use of pneumococcal vaccines. In these different moments through which scalability is accomplished, always partially and temporarily, we show that a dual activity can be witnessed, a pivoting between referential work and forward projection. To conclude, we suggest that scalability is more usefully approached as a form of expansion that is always attentive to the possibilities of change.  相似文献

Abstract

This paper explores an example of global politics in action by attending to the modalities and outcomes of United Nations negotiations on global warming. More precisely, the paper ethnographically traces how the capacity of tropical forests to act as carbon sinks is turned into a matter of global concern. The focus is on a negotiated policy called Reducing Emissions from Deforestation and forest Degradation (REDD+) and its anchoring in the Democratic Republic of the Congo, whose territory contains the second largest area of rainforest after Brazil. The paper discusses the importance of the promissory in climate actions, the multivalence of what is at stake and the porosity and resilience of national demarcation. To do so, it identifies three moments and sites of geopolitical re-composition: the formulation of international consensus, the work of preparatory agents and the quest for metrological inclusiveness. These moments and sites point to the theatricality and semi-secrecy of United Nations negotiations, the mobilizing activities of expatriate consultants hired with overseas aid funding and the unstable evidential grounds on which emission reduction efforts are based. The paper suggests that, through this series of processes, the carbon stored by tropical forests becomes a matter of global exigency.  相似文献

Early alcohol use is associated with multiple negative outcomes later in life, including substance use disorders. Identification of factors related to this very early risk indicator can help inform early prevention efforts. This study prospectively examined the relationship between childhood adversities and early initiation of alcohol use (by age 14) among Puerto Rican youth, the Latino subgroup at highest risk for alcohol use disorders in adulthood. The data come from the Boricua Youth Study, a longitudinal study of Puerto Rican youth in two sites (South Bronx, New York, and the standard metropolitan area of San Juan, Puerto Rico). We focus on youth who were ages 10 and older at Wave 1 [M age at Wave 1 (SE)?=?11.64(0.05), N?=?1259, 48.85?% females]. Twelve childhood adversities were measured at Wave 1 and include 10 adverse childhood experiences commonly studied and two additional ones (exposure to violence and discrimination) that were deemed relevant for this study’s population. Early initiation of alcohol use was determined based on youth report at Waves 1 through 3 (each wave 1 year apart). Cox proportional hazards models showed that, when considered individually, adversities reflecting child maltreatment, parental maladjustment, and sociocultural stressors were related to early initiation of alcohol use. Significant gender interactions were identified for parental emotional problems and exposure to violence, with associations found among girls only. Adversities often co-occurred, and when they were considered jointly, physical and emotional abuse, parental antisocial personality, and exposure to violence had independent associations with early alcohol use, with a stronger influence of exposure to violence in girls compared to boys. The accumulation of adversities, regardless of the specific type of exposure, increased the risk for starting to drink at a young age in a linear way. The associations between childhood adversities and early alcohol use were generally consistent across sociocultural contexts, in spite of differences in the prevalence of exposure to adversity. Our findings highlight the importance of targeting multiple adversities and expanding the notion of adversity to capture the experiences of specific groups more adequately.  相似文献

Two discreet choice experiments investigated how three styles of leadership (i.e., transformational, transactional, and ethical) and three job features aimed at activating different motivational forces (i.e., public service motivation, external regulation, and intrinsic motivation) simultaneously and independently affected the job preferences of a sample of public employees. Subjects displayed a strong preference for jobs that benefit more citizens, that are more interesting, and that require working under ethical leaders rather than unethical ones. Whereas the prospect of a 5% salary increase strengthened participants’ preferences for a given position, offering a 1% salary raise did not significantly change subjects’ job choices. Furthermore, participants did not appear to have any preference for working under a transformational leader rather than a transactional leader.  相似文献

Employee turnover—due to retirement, moving from one work unit to another, or leaving an organization entirely—imposes considerable costs on organizations. While private organizations make use of several high-powered incentives to retain workers, public organizations typically lack comparable incentives. Fortunately, public employees frequently possess stronger intrinsic motives to stay. Our results indicate that employee voice is an especially useful tool in the U.S. federal government. Evidence is also consistent with a substantial “contagion” effect: when others in an agency seek to leave, individual employees in that agency are more likely to report turnover intentions than similar employees in agencies with more “stayers.”  相似文献

Educational approaches that enable students to actively and directly participate in “real-world” projects are increasingly recognized as valuable pedagogical tools and, as such, being incorporated into university curriculums worldwide. Though not traditionally associated with political science courses, project-based international service learning presents a tremendous opportunity to bring classroom concepts and theories to life, provide an active approach to addressing international challenges, and assist students in the development of the hands-on, problem-solving, team-based, critical-thinking skills that are increasingly important to employers across all sectors. This article seeks to encourage political science faculty to incorporate international service learning—and/or project-based approaches—into their educational offerings. Through examination of the course Global Synthesis in Liberal Arts and Engineering Studies at California Polytechnic State University, we have identified multiple factors that can help promote successful execution of project-based international service learning as a pedagogical tool, and provide additional suggestions for faculty interested in adopting specific aspects of these educational approaches, and/or in doing so closer to home.  相似文献
