This study examines the appropriation of grammatical structures of African American English (AAE) by adolescent Latinos attending a multi‐ethnic middle school in North Carolina. The study couples quantitative variationist analysis of four ‘core’ grammatical features of AAE (invariant be, copula deletion, past‐tense copula leveling, and third‐person singular –s absence) with the findings of an ethnographic study of Latino adolescent identity in order to better understand the social processes leading to the incorporation of AAE grammar into English varieties spoken by Latinos. Results show that Latino students from across social formations make use of AAE grammatical features, but differ significantly from African American students in terms of sociolinguistic patterning. Ethnographic data shed light on linguistic data in three domains: (1) differences in use of AAE structures between male and female Latino/a students; (2) the prolific use of AAE by one gang‐affiliated student; and (3) the racial complexities within the ethnic category ‘Latino.’  相似文献

This study investigates the phenomenon of building big dwellings in contemporary Saudi society. It relates the size of the contemporary villa-type dwelling with the traditional dwelling, and it compares it to a number of average (standard) international dwellings. It questions the rationale of its large size; hence, it argues against leaving this trend to continue unchecked. It further defines and discusses factors which influence the dwelling size, i.e. economic, socio-cultural, and new building practice and trade. The aim of this research is to draw attention to this phenomenon, to inform those involved in housing policy and design of the extent of size-related problems in terms of initial construction and furnishing cost and in terms of operating and maintenance life-cycle cost, and to call for further research to investigate its social, environmental, and economic impact on the country and its population.  相似文献

Asbestos lung cancer risks: comparison of animal and human extrapolations   总被引:1,自引:0,他引:1  
Using the most comprehensive inhalation study available, (Wagner, et al., 1974), the dose-response effects of the four major types of asbestos fibers (amosite, anthophyllite, crocidolite, and chrysotile: Canadian, Rhodesian) for lung cancer have been determined. From linear regression analysis of the animal data and five human epidemiology studies giving a wide range of risk estimates, slopes of the curves have been determined and lifetime risk estimates made. Projected risks for rats are presented with and without surface area (s.a.) conversion factors. On the basis of cumulative exposure, the geometric mean of the point estimates for the human studies (0.0146) is quite close to the geometric mean of the animal data (0.0179 without s.a.; 0.0122 with s.a. calculations). These values also match quite well if one of the studies (McDonald, et al.) is eliminated (geometric mean = 0.031) due to qualitatively different exposure considerations (mining and milling vs. industrial environments). Animal risks based on a concentration per day basis (assuming an average 70-year lifespan for humans) are below the lowest human estimate but within 5-6 fold (less) of the projected risk from nonsmoking asbestos workers (2.2 X 10(-3) using the Hammond et al. study.  相似文献

Heeding the call put out by the New England Journal of Medicine (2017), we utilize an ecological–transactional model as a conceptual framework for understanding existing literature and for guiding future research on immigration enforcement threat and Latino child development. Using the World Health Organization's definition of violence, we draw on literature from psychology, medicine, social work, and developmental psychology to outline how the anti-immigrant climate in the United States and the threat of immigration enforcement practices in everyday spaces are experienced by some Latino children as psychological violence. Researchers, teachers, and practitioners are encouraged to be aware of how uncertainty and threat regarding familial safety adversely impacts the lives of Latino children in immigrant households, especially in charged, anti-immigrant climates.  相似文献

Over the past few decades, numerous studies have been conducted on the trade-off between guns and butter, namely defence spending versus social sector expenditure. It is striking that none has examined the situation in Spain. Previous research on other countries has not provided strong and unambiguous evidence of either positive or negative effects for military expenditure on social spending. We test whether government expenditure on defence contributed positively or negatively to education spending in twentieth-century Spain, attempting to identify policy-making processes within a historical framework. The results show both direct and indirect effects and bring to light the negative consequences of military spending on education expenditure, in particular between the second and fifth year after the military expenditure increases.  相似文献

Sociologists mostly treat age-at-arrival as a dichotomous variable whereas economists often approach it as a continuous variable. This article extends this debate by addressing a set of political behaviours that has mostly been the purview of political scientists. Analysing restricted, geocoded data from the National Survey of Latinos on Politics and Civic Participation, this article examines how age-at-arrival and civic institutions shape political participation among Latino immigrants. Logistic regression and random effects models suggest three key findings. First, age-at-arrival has a strong impact on participation, with child arrivals showing the highest level of participation and midlife arrivals reporting the lowest level of participation. Second, there are no ethnic differences in the likelihood of participating in non-electoral politics among Latinos. Third, involvements with civic institutions significantly shape political participation, confirming these institutions’ potential role in cultivating political efficacy and participatory skills. At the same time, the impact of civic organisations on political participation is contingent on both the type of organisation and the immigrant’s age-at-arrival, with ethnic organisations playing an important role in the political resocialisation process. Finally, ethnic concentration at the county has limited positive impact on political participation.  相似文献

This article describes factors that predict the use of early childhood education and care among Latino families, as compared to non-Latino black and non-Latino white families in the United States in two age groups (0–2 and 3–5 years old). Using National Household Education Survey data, this study presents a framework and examines the association of numerous child and family characteristics with the number of hours children spend in care, the number of care arrangements, and the type of care used. Multinomial logit results show that once preexisting differences between Latino and black families and between Latino and white families are equalized, differences in the type of care are often eliminated. Findings suggest that the observed enrollment patterns of Latino children are due in part to their over-representation in families that are poorer, have lower levels of maternal education, and have lower levels of maternal employment.  相似文献

The geographic diffusion of Latinos from immigrant gateways to newly-emerging rural destinations is one of the most significant recent trends in U.S. population redistribution. Yet, few studies have explored how Latinos have fared in new destinations, and even fewer have examined economic implications for other minority workers and their families. We use county-level data from the 1990 and 2000 U.S. Census and the 2006–2010 American Community Survey to compare the changing economic circumstances (e.g., employment and unemployment, poverty, income, and homeownership) of Latinos and African Americans in new Latino boomtowns. We also evaluate the comparative economic trajectories of Latinos in new destinations and established gateways. During the 1990s, new rural destinations provided clear economic benefits to Latinos, even surpassing African Americans on some economic indicators. The 2000s, however, ushered in higher rates of Latino poverty; the economic circumstances of Latinos also deteriorated more rapidly in new vis-à-vis traditional destinations. By 2010, individual and family poverty rates in new destinations were significantly higher among Latinos than African Americans, despite higher labor force participation and lower levels of unemployment. Difference-in-difference models demonstrate that in both the 1990s and 2000s, economic trajectories of African Americans in new Latino destinations largely mirrored those observed in places without large Latino influxes. Any economic benefits for Latinos in new rural destinations thus have not come at the expense of African Americans.  相似文献

How much discretion should the monetary authority have in setting its policy? This question is analyzed in an economy with an agreed‐upon social welfare function that depends on the economy's randomly fluctuating state. The monetary authority has private information about that state. Well designed rules trade off society's desire to give the monetary authority discretion to react to its private information against society's need to prevent that authority from giving in to the temptation to stimulate the economy with unexpected inflation, the time inconsistency problem. Although this dynamic mechanism design problem seems complex, its solution is simple: legislate an inflation cap. The optimal degree of monetary policy discretion turns out to shrink as the severity of the time inconsistency problem increases relative to the importance of private information. In an economy with a severe time inconsistency problem and unimportant private information, the optimal degree of discretion is none.  相似文献

In the present study, young (n = 34) and older(n = 70) adult volunteers at either animal (n= 48) or human (n = 56) homeless shelters were asked to complete measures of caregiver stress/satisfaction, volunteer motives, and social desirability. Young compared to older volunteers assisting animals, but not humans, reported a significantly higher caseload and spending significantly more time per visit with their clients. In addition, young volunteers reported significantly higher levels of caregiver stress with humans more than animals. Also, volunteers at human (but not animal) homeless shelters claimed the need for meeting social expectations as a motive for community service. Furthermore, younger compared to older volunteers reported gaining relevant career experience, obtaining a knowledge of the plight of others, relieving aversive emotions, and meeting normative expectations as significant motives for volunteering. These results may have important implications for recruitment and training of community volunteers at homeless shelters.  相似文献
