The recruitment of Pacific Island labourers for Queensland, Australia, 1863–1904, has often been seen through comparisons to the transatlantic slave trade. Yet the fact that men from Antigua, Barbados and Jamaica pushed for justice after one of the most notorious atrocities of the trade has very rarely been noted, their involvement mired by racist reporting of the case. If seen from the perspective of their Caribbean homelands, their words and actions, often misinterpreted by Queensland's courts and media, can be seen as latter-day resistance to enslavement, oppression and racism.  相似文献

Little is known about the relatedness structure of carnivores living in urban areas, where green spaces may vary in size and resource availability. We examined the minimum population size, relatedness structure, and genetic diversity of a recently established population of eastern coyotes (Canis latrans) inhabiting New York City (NYC). The population has been established for approximately 25 years, and sample collection for genetic analysis has been ongoing since 2010. We genotyped 234 scat, eight tissue, and three blood samples at nine microsatellite loci. We identified 45 individual coyotes with a male-biased sex ratio of 2.2:1. We also found moderate to high levels of genetic diversity, with average observed heterozygosity of 0.779 and mean number of alleles per locus of 7.8. Most of the green spaces surveyed supported a single group of closely related coyotes in each. Relatedness comparisons between parks also indicated that coyotes compared across different parks were also closely related. We identified two unrelated mated pairs and found no support for polygamy. The high incidence of relatedness suggests that the coyote population is descended from a small number of founding individuals. Additionally, we genetically recaptured several coyotes, including one individual sampled in the Bronx and in Queens, with a median of 103 days between resampling. This result indicates that the coyotes are persisting in some of the isolated greenspaces of New York City and able to move successfully between them.

Adolescence is a time of identity exploration, and preliminary evidence indicates the ways adolescents are describing their sexual and gender identities (SOGI) are changing. A nuanced understanding of SOGI is necessary for valid assessment in developmental research. Current measures do not capture the diversity of emerging identities among young people. Our study analyzed a national sample of 17,112 sexual and gender minority adolescents (13–17 years) to better understand how identity labels are reported across sexual, gender, and ethnoracial minorities. Adolescents reported 26 distinct SOGI categories; 24% of adolescents utilized nontraditional SOGI labels, such as pansexual and nonbinary. These identifications varied significantly as a function of ethnoracial identity. Results have implications for how scholars conceptualize and measure SOGI among adolescents.  相似文献

To theorize the process by which behaviors once regarded as deviant become normalized, this article analyzes the legalization of a state‐run lottery in the American state of Massachusetts. Lotteries are an important case to study the dynamism of socially constructed problems as well as the creation of gaming markets because they raise moral, social, and economic concerns associated with all types of gaming with the added dimension of having the state government serving as regulator and proprietor of the wagering. Drawing on newspaper articles and archival records, this article examines mobilization around failed efforts to establish a lottery in Massachusetts in the 1930s and 1950s, followed by the successful legalization of a lottery in the 1970s. Highlighting meaning making collective struggles over the lottery in variable circumstances illuminates the processes by which the perceptions of proprietors of operations, patrons of the games, and the distribution of proceeds shift, ultimately turning what was once an illegal enterprise into a socially accepted state institution.  相似文献

State-directed but market-oriented forms of regulation, especially environmental examples like cap-and-trade and ecological offsetting, have proliferated in the past two decades, but sociologists have been slow to theorize these broad institutional shifts. This article offers a framework for explaining these processes of regulatory marketization. First, I argue that institutions of this sort are examples of what I call command-and-commodify regulation, a mode of regulation that distinctively hybridizes economic and authoritative dimensions of power. Second, I explain how and why one example of command-and-commodify regulation, species conservation banking, emerged and remained concentrated in California, but did not so easily develop in other American states. Finally, abstracting from the case, I argue that the concept of market reconstruction is useful for developing a more general theory of the ways that social conflicts and mobilization reconfigure regulatory power and thus give rise to new modes of regulation. Together, a theory of command-and-commodify regulation and market reconstruction may be useful for explaining the development of a wide variety of environmentally focused and other regulatory institutions.  相似文献

This study explored the phenomenon of career anxiety through a qualitative investigation of the experiences of 7 traditional‐aged college students who were in various stages of their undergraduate degree programs. Using Moustakas's ( 1994 ) method of transcendental phenomenology, the authors conducted in‐depth interviews to answer the following questions: (a) What are coresearchers’ (participants') experiences with the phenomenon of career anxiety? and (b) In what contexts do the coresearchers experience career anxiety? Seven themes emerged: general symptoms of anxiety, existential concerns, pressure, lack of career guidance, cognitive distortions, social comparisons, and economic/occupational uncertainty. The findings provide a contextual and developmental perspective on career‐related anxiety that can guide counselors in the implementation of interventions for reducing anxiety associated with career choice and development.  相似文献

Research on nonprofit lobbying conceives of strategy in various ways. This article presents a more comprehensive view encompassing four components: lobbying motivation (lobbying for organizational or self-interest as well as for societal benefit), concentration (lobbying in a narrow versus wide range of policy domains), type (lobbying policymakers directly or indirectly), and target (lobbying different levels of government). Based on the analysis of the population of nonprofit organizations that registered to lobby in the State of North Carolina in 2010 (N = 402), findings demonstrate the complexity and distinctiveness of nonprofit lobbying strategies: Most nonprofits register to lobby for organizational and societal benefit, in multiple policy domains, directly and indirectly, and at several levels of government. The article discusses the findings and their implications and suggests a research agenda on nonprofit lobbying strategy that would incorporate the roots of these strategic choices.  相似文献

This study examined gambling behavior in the context of a newly opening casino, comparing disordered gamblers to non-disordered gamblers, in a population of individuals involved in methadone maintenance treatment. Disordered gamblers (N = 50) and non-disordered gamblers (N = 50) were surveyed before and after the opening of a new casino on gambling behaviors, substance use, and psychological symptoms. No statistically significant changes in gambling behaviors were observed for disordered gamblers or non-disordered gamblers across time points; however, non-disordered gamblers demonstrated non-significant increases in horse and dog race betting, electronic games, and casino table games. As expected, disordered gamblers were found to spend significantly more money on electronic games and casino table games (p < 0.05) and demonstrated higher rates of drug use and impulsivity than non-disordered gamblers. The introduction of a new casino did not appear to have a major impact on gambling behaviors of individuals attending methadone maintenance treatment, though the non-significant increases in gambling among non-disordered gamblers may indicate that this population is preferentially impacted by the opening of a new casino. Future investigation into the longer term effects of opening a new casino on this population may be warranted.  相似文献
