This article uses Probation Department files to reconstruct the lives of five ordinary residents of Harlem. It highlights what that black metropolis offered those outside the political and cultural elite, who have dominated historical scholarship, showing how ordinary blacks negotiated the challenges of life in northern neighborhoods, and drew on institutions and organizations, to establish and sustain new lives. We offer the kind of individualized perspective on everyday life that other scholars have provided for high culture, but which does not exist for other realms of existence in Harlem, even in early twentieth century sociological studies of black life. Where scholars seeking to distinguish the neighborhood from a slum have pointed to the prevailing pride and self-confidence of its residents, this article directs attention to more immediate, concrete supports that sustained and enriched life in Harlem. Relationships with spouses, children, siblings and cousins sustained individuals faced with the social reality of living in overcrowded, deteriorating, disease infested housing, subject to the racism of white police, politicians and employers; so too did friendships made in nightclubs, speakeasies, dances and movie theatres, and membership of churches, fraternal organizations, social clubs, and sports clubs and teams. 相似文献

In this note, we consider the problem of estimation of coefficient of dispersion of a study variable by making use of known value of the coefficient of dispersion of an auxiliary variable. We propose ratio and regression-type estimators. We derive expressions of bias and variance of the proposed estimators to the first order of approximation. The relative efficiencies of the ratio and regression-type estimators with respect to the naïve estimator are investigated through a simulation study. 相似文献

In this paper, we introduce a new problem of simultaneous estimation of means of two quantitative sensitive variables by using only one randomized response another pseudo response from a respondent in a sample. The proposed estimators are extended to stratified random sampling, and the relative efficiency values are computed for equal, proportional, and optimum allocation with respect to the newly introduced naïve estimators. 相似文献

In this article, we outline a simple and intuitively appealing procedure to derive default priors. The main idea is to regard
the choice of such a prior as a formal Bayesian decision problem. We also discuss Jeffreys prior and more generally the reference
prior of Bernardo (J R Stat Soc B 41:113–147, 1979) from this standpoint. 相似文献

Abstract Although there have been major declines in the incidence of measles and rubella in the United States since licensure of vaccines, the incidence of disease in adolescents and young adults has not declined nearly as markedly as that in younger children. As a result, an increasing proportion of cases have occurred in adolescents and young adults. In 1978, 26% of all reported measles cases in which age was known occurred in those 15 years of age and older, and 76% reported rubella cases occurred in this age group. Outbreaks of both diseases have been reported from high schools, military bases, colleges, and universities. During a recent outbreak of measles involving a university, a 22-year-old university employee contracted measles and died of measles encephalitis. In addition to the direct effects of these diseases, the implications of the current pattern of occurrence of two infections known to have adverse effects on the developing fetus are obvious. Improvements in immunization levels and declines in disease incidence have been brought about effectively by the enactment and enforcement of immunization requirements for school-age children and military recruits. Colleges and universities should also institute immunization requirements as a condition of enrollment. 相似文献

ABSTRACT Objective: The present study extends research on campus smoking bans by examining where smokers are violating the policy at a large university in the southeastern region of the United States. Participants: The data collection was conducted by one graduate student from the university in August of 2014. Methods: A global positioning system device was used to collect the geo-coordinates of littered cigarette butts as a proxy measure for smoking violations. Results: A hot spot analysis found a number of spatial concentrations on campus, largely around classroom and administrative buildings along with parking lots and garages. Conclusions: The implications of such findings can direct enforcement to target these areas in order to reduce offenses and fulfill the initial goals of policy-makers and university administrators who support smoke-free campuses. 相似文献

Evaluation of a group parenting programme in the Northern Territory of Australia showed significant differences in benefits for Aboriginal and non‐Aboriginal boys and girls. The analysis considers whether boys and girls from different cultural backgrounds present with different problems; whether parental expectations for boys and girls differ and whether the intervention activates different responses in different settings. Conclusions suggest that there is a need to closely examine the ‘cultural logic’ of interventions, the appropriateness of their assumptions about child development and hypothesised mechanisms of change in different settings. 相似文献
