Sexual minority youth report higher rates of depression and suicidality than do heterosexual youth. Little is known, however, about whether these disparities continue as youth transition into young adulthood. The primary goals of this study were to describe and compare trajectories of adolescent depressive symptoms and suicidality among sexual minority and heterosexual youth, examine differences in depressive symptoms and suicidality trajectories across sexual orientation subgroups, and determine whether there are gender differences in these longitudinal disparities. Four waves of data from the National Longitudinal Study of Adolescent Health were analyzed using latent curve modeling (N = 12,379; 53 % female). Results showed that the rates of depressive symptoms and suicidality in early adolescence were higher among sexual minority youth than among heterosexual youth, and that these disparities persisted over time as participants transitioned into young adulthood. Consistent with previous cross-sectional studies, the observed longitudinal disparities were largest for females and for bisexually-identified youth. Sexual minority youth may benefit from childhood and early adolescent prevention and intervention programs.  相似文献

Peasant uprisings in the Tokugawa period have been studied by Japanese scholars since the Second World War as ‘manifestations of the struggle of the oppressed masses against the despotic power of the feudal system’, but Hugh Borton, the doyen of American scholars concerned with Japanese peasant studies, argues in the introduction to a reissue of his 1938 opus that there is little new evidence to support this prevailing interpretation. His somewhat cavalier dismissal of the thesis is based on the premise that only a concerted effort by peasants of many regions to overthrow the feudal system could be considered a revolutionary struggle. It will be the purpose of this paper to demonstrate that concerted efforts by peasants in many of the relatively autonomous domains, though often uncoordinated, mounted a serious challenge to the various feudal regimes, and moreover, that peasants often developed a keen political consciousness and effective, though impermanent, political organisation in the years before a new stratification within the peasant class disrupted the struggle in the latter half of the eighteenth century.  相似文献

This article focuses on two memoirs written by Cornelia Sorabji in the 1930s – India Calling (1934), and a subsequent book, India Recalled (1936) – in order to explore how discourses of space and place shaped the representations of femininity which structure these texts. Specifically, I will examine Sorabji's apprehensions of femininity in relation to the Muslim and Hindu women she viewed as her legal ‘clients.’ I am equally interested in these texts as evidence of how memory works as a practice of history – how events as they were recalled and recorded in the volatile 1930s and, especially in the wake of the Katherine Mayo controversy, how they helped shape the versions of the respectable feminine produced in her public writing of the period.  相似文献

Environmental surface sampling is crucial in determining the zones of contamination and overall threat assessment. Viability retention of sampled material is central to such assessments. A systematic study was completed to determine viability of vegetative cells under nonpermissive storage conditions. Despite major gains in nucleic acid sequencing technologies, initial positive identification of threats must be made through direct culture of the sampled material using classical microbiological methods. Solutions have been developed to preserve the viability of pathogens contained within clinical samples, but many have not been examined for their ability to preserve biological agents. The purpose of this study was to systematically examine existing preservation materials that can retain the viability of Bacillus anthracis vegetative cells stored under nonpermissive temperatures. The results show effectiveness of five of seventeen solutions, which are capable of retaining viability of a sporulation deficient strain of B. anthracis Sterne when stored under nonrefrigerated conditions.  相似文献

A basic median-voter model is developed and extended to analyze issues of economic regulation and public policy outcomes. The model is used to generate comparative static results relating changes in public-policy outcomes to changes in relative group sizes, total population, information costs, and population heterogeneity. The model is also used to explore the issue of optimal group size — the size of the special-interest group that maximizes the group's per capita public policy gains. Comparative static analysis reveals how optimal group size and gains per capita are affected by changes in population heterogeneity, the size of the total population, and relative knowledge levels.  相似文献
