Policies that regulate peoples international movement and their state membership have historically made distinctions based on perceived sexual differences, but little is known about the process by which this has happened. This paper explores how and with what consequences migration and nationality policies have been gendered in two quintessential countries of emigration (Italy and Spain), and in a country of immigrants (Argentina) over a 150-year period. I argue that these migration and nationality policies have reflected the dynamics of the political fields in which they have been crafted. Especially before the Great War, laws and official practices that showed a disproportionate interest in men as soldiers and workers, and in women as mothers and as morally suspect subjects mirrored a dynamic of competition over migrants among these countries. A subsequent harmonization of policies reflected a dynamic of accommodation to the realities of a settled emigrant population and dual nationality. In addition, the administrative mechanisms coupled with these laws have operated differently with respect to men and women. The consequences of these laws and mechanisms have persisted even when the letter of the law has ostensibly become gender neutral.  相似文献

Sweden and France are in many respects in the vanguard of high-level radioactive waste disposal efforts, and they offer sharp contrasts regarding basic strategies and underlying philosophies for waste management. We compare their waste disposal programs for insight into the dilemma of siting and developing a permanent waste repository. We find that technical decisions, as well as the more obvious sociopolitical decisions about repository development, are shaped by deep-seated social and political forces in each nation.  相似文献

In a previous study, 18 repeated exposures of anaesthetized swine to an electro-muscular incapacitating device (TASER International's ADVANCED TASER X26 electronic control device) resulted in acidosis and increases in blood electrolytes. In the current study, experiments were performed to investigate effects of a more typical scenario of repeated exposures of the device on muscle contraction and changes in blood factors. Ten swine were exposed for 5s, followed by a 5-s period of no exposure, three times. Selected blood factors were monitored for 3h following exposure. Transient increases in blood glucose, lactate, sodium, potassium, calcium, and pCO(2) were consistent with previous reports in the literature dealing with studies of muscle stimulation or exercise. Blood pH was decreased immediately following exposure, but subsequently returned toward a normal level. Oxygen saturation (measured by pulse oximetry) was not changed significantly. In conclusion, three repeated TASER device exposures had only transient effects on blood factors, which all returned to pre-exposure levels, with the exception of hematocrit (which remained elevated after 3h). Since the increase in this factor was less than that which may occur after short periods of exercise, it is unlikely that this would be an indicator of any serious harm.  相似文献

Anglican church commemoration in Barbados is traditionally viewed as reflecting a wholly white, British history; however, beginning in the late eighteenth century, these spaces were circumvented as places of memory for the freed black community. As abolition and emancipation triggered greater integration of previously racially segregated groups on the island, funerary monuments provided the opportunity to negotiate memory, social structure, and community relationships, subverting dominant power hierarchies and tensions stimulated by race, religion, and marginalization. This paper will reconstruct narratives and counter-narratives in burial practice and monument use against the backdrop of abolition and emancipation to contribute to historical and archaeological understandings of historical processes of colonization and decolonization, relevant to Barbados and other colonies dependent on slave labour.  相似文献

Online Network Influences on Emerging Adults’ Alcohol and Drug Use   总被引:1,自引:0,他引:1  
Researchers have reported that network characteristics are associated with substance use behavior. Considering that social interactions within online networks are increasingly common, we examined the relationship between online network characteristics and substance use in a sample of emerging adults (ages 18–24) from across the United States (N = 2,153; M = 21 years old; 47 % female; 70 % White). We used regression analyses to examine the relationship between online ego network characteristics (i.e., characteristics of individuals directly related to the focal participant plus the relationships shared among individuals within the online network) and alcohol use and substance use, respectively. Alcohol use was associated with network density (i.e., interconnectedness between individuals in a network), total number of peer ties, and a greater proportion of emotionally close ties. In sex-stratified models, density was related to alcohol use for males but not females. Drug use was associated with an increased number of peer ties, and the increased proportion of network members’ discussion and acceptance of drug use, respectively. We also found that online network density and total numbers of ties were associated with more personal drug use for males but not females. Conversely, we noted that social norms were related to increased drug use and this relationship was stronger for females than males. We discuss the implications of our findings for substance use and online network research.  相似文献

Using administrative data on public school students in North Carolina, we find that sixth grade students attending middle schools are much more likely to be cited for discipline problems than those attending elementary school. That difference remains after adjusting for the socioeconomic and demographic characteristics of the students and their schools. Furthermore, the higher infraction rates recorded by sixth graders who are placed in middle school persist at least through ninth grade. An analysis of end‐of‐grade test scores provides complementary findings. A plausible explanation is that sixth graders are at an especially impressionable age; in middle school, the exposure to older peers and the relative freedom from supervision have deleterious consequences. These findings are relevant to the current debate over the best school configuration for incorporating the middle grades. Based on our results, we suggest that there is a strong argument for separating sixth graders from older adolescents. © 2008 by the Association for Public Policy Analysis and Management.  相似文献
