We estimate the size of the African American population in five-year age groups at census dates from 1930 to 1990 using a three-part strategy. For cohorts born after 1935, we follow the U.S. Census Bureau in using classical demographic analysis. To estimate the size of cohorts born before 1895, we use extinct-generation estimates. For remaining cohorts, we implement an age/period/cohort model of census counts. All approaches are applied to a data set in which the age distribution of deaths has been corrected for age misreporting. Results provide strong confirmation of the basic validity of Census Bureau estimates of census undercounts for African Americans while extending estimates to new cohorts and periods. Our estimates are less consistent with an historical series prepared by Coale and Rives (1973). 相似文献

The Australian Bureau of Statistics provides population estimates of Statistical Local Areas annually. The accuracy of these estimates can be assessed after population estimates are rebased after each quinquennial Census of Population and Housing, however there appears to be no straightforward method of assessing these estimates. Errors that occur with population estimates can be attributed to several factors, both broad and specific to individual areas. These factors include inherent characteristics of the region, such as population size and growth rate; changes in the geographic boundaries; quality of input data; estimation method; and adjustments to control totals (state populations). 相似文献

Researchers consistently report links between psychological control and adolescent behavior problems, but the processes linking psychological control with behavior problems are unclear. Adolescents’ negative emotional reactions and psychological reactance were tested as potential longitudinal mediators linking parental psychological control with both internalizing and externalizing behavior problems. Data were collected from a sample of 242 adolescents (M age = 15.4 at Time 1; 50.8% female; 50% white, non‐Hispanic, 18% African American, 16% Hispanic, and 16% of other or multiple ethnicities) at three time points over a 2‐year period. Adolescents self‐reported depressive symptoms, antisocial behavior, negative emotional reactions, and psychological reactance. Adolescents and their parents provided ratings of parental psychological control. Cross‐sectional models replicated patterns previously reported suggesting that negative emotional reactions and reactance mediate between psychological control and internalizing and externalizing behavior problems. However, in cross‐lagged panel models, neither negative emotional reactions nor reactance emerged as a mediator between psychological control and internalizing or externalizing problems. In contrast, results suggested that psychological control is an outcome of rather than contributor to, negative emotional reactions. Moreover, the addition of random intercepts to cross‐lagged models indicated that associations between psychological control, emotional and behavioral reactions, and internalizing/externalizing behavior may represent stable trait‐like patterns. 相似文献

This article illustrates how the linguistic‐anthropological notion of axes of differentiation can illuminate translanguaging practices. Through an analysis of media texts, it explores the ways in which multilingual Hongkongers draw on their semiotic repertoires to make sense of Xiqu Centre as the English name of the recently inaugurated center for traditional Chinese theater in their city. Against the backdrop of different axes of differentiation, supporters and detractors contrast the Putonghua word xìqǔ “traditional Chinese theater” with its equivalents in English and Cantonese respectively, thereby arriving at diametrically opposed interpretations of the name. While many detractors engage in interpretive practices that challenge the discreteness of linguistic systems, others who use their multilingual knowledge to criticize the name appeal to ideologies of linguistic purism. To fully understand multilinguals’ production and interpretation of signs, we need to examine not only communicative practices that disrupt language boundaries but also those practices that do not. 相似文献

In this paper, I study the application of various specification tests to ordered logit and probit models with heteroskedastic errors, with the primary focus on the ordered probit model. The tests are Lagrange multiplier tests, information matrix tests, and chi-squared goodness of fit tests. The alternatives are omitted variables in the regression equation, omitted varaibles in the equation describing the heteroskedasticity, and non-logistic/non-normal errors. The alternative error distributions include a generalized logistic distribution in the ordered logit model and the Pearson family in the ordered. 相似文献

Much has been written about the beginning phase of family therapy, little about the end. Joining may be said to set the tone for later therapy, ending establishes directions for the future. As such, this last and crucial phase of therapy warrants careful study. This paper examines the importance of the last session of therapy for both family and therapist, and illustrates techniques which may facilitate future change. 相似文献

There is a growing interest in, time allocation research. Particularly by government statistical bodies. Papers in this issue, briefly highlighted in this introduction, make a small contribution to fulfilling a need for wider exposure of time use literature. The included papers do two things. First, they identify issues related to the collection and analysis of time use data. Second, they show how time use data can be effectively applied to improve one's understanding of significant issues. 相似文献
