The narrative and dual-cycle approach conceptualize and operationalize adolescents’ identity formation in different ways. While the narrative approach focuses on the construction of an autobiographical life story, the dual-cycle approach focuses on the formation of identity commitments. Although these approaches have different emphases, they are conceptually complementary. Yet, their empirical links and distinctions have only scarcely been investigated. Empirical knowledge on these links in adolescence and across time has been especially lacking. In the present research, it was therefore examined whether key characteristics of adolescents’ narration (autobiographical reasoning and agency) were concurrently and prospectively related to engagement in the dual-cycle processes of commitment making, identification with commitment, exploration in breadth, exploration in depth, and ruminative exploration. The findings from a cross-sectional sample of 1,580 Dutch adolescents (Mage?=?14.7 years, 56% female) demonstrated that autobiographical reasoning was significantly positively associated with the commitment and more adaptive exploration processes (i.e., in breadth and in depth). In addition, agency was significantly positively associated with the commitment processes and exploration in depth. Yet, these associations between the narrative characteristics and dual-cycle processes were only weak. Subsequently, the findings from a two-year longitudinal subsample (n?=?242, Mage?=?14.7 years, 62% female) indicated that on average commitment strength remained stable but exploration increased across middle adolescence. A stronger increase in identification with commitment and adaptive exploration (i.e., in breadth and in depth) was predicted by a higher degree of agency in adolescents’ narratives. Overall, these findings indicate that both approaches to identity formation are associated, but the small size of these associations suggests that they predominantly capture unique aspects of identity formation. Both approaches could thus complement and inform each other.

In the United States, opioid-related mortality has tripled since 2000, leading the Centers for Disease Control to declare a national overdose epidemic in 2016. With overdose an increasing area of mainstream political and popular concern, some commentators have suggested that sympathetic attention has followed changes in the profile of opioid users, as rates of heroin initiation have doubled among white Americans and women. Yet no studies have examined how media framings of overdose have shifted alongside the epidemic’s demographic contours. Focusing upon southwestern Pennsylvania, this study uses qualitative analysis of news items surrounding three surges in heroin overdose deaths in 1988, 2006, and 2014. 178 items reporting on such overdose outbreaks were selected for thematic coding, with attention directed toward opioid user representations, “drug problem” characterizations, and suggested solutions. Results reveal a transformation in the depiction of overdose sufferers over time, with stories increasingly centered around “unexpected” opioid users, whose habits are made legible through biomedical discourses of addiction; such portraits are used to argue the impropriety of punitive responses to drug misuse. At the same time, the role of criminal justice institutions in addressing overdose is not dismissed, but relocated in recent coverage, with the intensified prosecution of drug dealers offered by many.  相似文献

This paper explores the policing of a traditional wholesale fruit market located in a densely populated neighborhood of urban Hong Kong. Based on ethnographic and historical research, we outline the political arrangements that govern the discretionary arrangements of police power at the market. A historically developed system maintains an informal status quo against various pressures to change. We identify crucial features in the contemporary policing system that emerge from a fusion between the democratic ethos of community policing ideals and non-democratic aspects of local administration in the Hong Kong Special Administrative Region. These features of this historically developed mode of order-maintenance, we suggest, might be seen as broadly characteristic of a “Hong Kong style” community policing.  相似文献

Body image and eating concerns are prevalent among early adolescent girls, and associated with biological, psychological and sociocultural risk factors. To date, explorations of biopsychosocial models of body image concerns and disordered eating in early adolescent girls are lacking. A sample of 488 early adolescent girls, mean age = 12.35 years (SD = 0.53), completed a questionnaire assessing depressive symptoms, self-esteem, body mass index (BMI), sociocultural appearance pressures, thin-ideal internalization, appearance comparison, body image concerns and disordered eating. Structural equation modelling was conducted to test a hypothetical model in which internalization and comparison were mediators of the effect of both negative affect and sociocultural influences on body image concerns and disordered eating. In addition, the model proposed that BMI would impact body image concerns. Although the initial model was a poor fit to the data, the fit was improved after the addition of a direct pathway between negative affect and bulimic symptoms. The final model explained a large to moderate proportion of the variance in body image and eating concerns. This study supports the role of negative affect in biopsychosocial models of the development of body image concerns and disordered eating in early adolescent girls. Interventions including strategies to address negative affect as well as sociocultural appearance pressures may help decrease the risk for body image concerns and disordered eating among this age group.  相似文献

Abstract

Many states faced fiscal pressures on their corrections budgets as the country entered a deep recession in 2008. A 2011 survey by the Association of State Correctional Administrators (ASCA) asked corrections officials in all 50 states about changes in correctional facilities, focusing on closures, new facilities, and altering existing facilities as a response to budget pressures. States employed a combination of these strategies. Between fiscal year (FY) 2007–2008 and FY 2011–2012, 148 facilities were closed, 29 new facilities were opened, and 23 states added 22,740 beds to existing facilities, resulting in about a 19,000 net bed reduction overall. Closures did not necessarily appear to be related to fiscal pressures or always related to reductions in the prison population. Despite the Great Recession, correctional funding is still a large part of state expenses and many states’ correctional populations continue to grow.  相似文献

Comparative Journal Ratings: A Survey Report   总被引:3,自引:3,他引:0  
The expert survey and bibliometric methods of assessing the quality of work in political science are complementary. This project builds on previous surveys of academic political science journals conducted among US political scientists. The current wave extends the survey to political scientists in Canada and the UK. Preliminary results suggest both similarities and differences across the three countries. These results matter for policy debate in any country that is considering channelling flows of funds to universities in proportion to the quality of their research, and in helping to supply objective evidence about the research quality of work submitted by candidates for academic appointments and promotions.  相似文献

Variability in the blood–breath ratio (BBR) of alcohol is important, because it relates a measurement of the blood-alcohol concentration (BAC) with the co-existing breath-alcohol concentration (BrAC). The BBR is also used to establish the statutory BrAC limit for driving from the existing statutory BAC limits in different countries. The in-vivo BBR depends on a host of analytical, sampling and physiological factors, including subject demographics, time after end of drinking (rising or falling BAC), the nature of the blood draw (whether venous or arterial) and the subject’s breathing pattern prior to exhalation into the breath analyzer. The results from a controlled drinking study involving healthy volunteers (85 men and 15 women) from three ethnic groups (Caucasians, Hispanics and African Americans) were used to evaluate various factors influencing the BBR. Ethanol in breath was determined with a quantitative infrared analyzer (Intoxilyzer 8000) and BAC was determined by headspace gas chromatography (HS-GC). The BAC and BrAC were highly correlated (r = 0.948) and the BBR in the post-absorptive state was 2 382 ± 119 (mean ± SD). The BBR did not depend on gender (female: 2 396 ± 101 and male: 2 380 ± 123, P > 0.05) nor on racial group (Caucasians 2 398 ± 124, African Americans 2 344 ± 119 and Hispanics 2 364 ± 104, P > 0.05). The BBR was lower in subjects with higher breath- and body-temperatures (P < 0.05) and it also decreased with longer exhalation times into the breath-analyzer (P < 0.001). In the post-absorptive state, none of the 100 subjects had a BBR of less than 2 100:1.  相似文献
