Differences between Southern and non-Southern blacks living in the North and West are considered for a wide variety of attributes such as employment, occupation, income, marital stability, and offspring's performance in school. Migrant blacks have generally more favorable rates than their Northern- and Western-born compatriots after standard domographic controls are applied to an unusually detailed set of cross-tabulations based on the One-Percent Sample Tapes for 1960. Perhaps the sharpest gap exists with respect to marital conditions; Southern blacks of both sexes are more likely to marry and, among those ever married, live more frequently with their spouses. Some of the results reported by earlier investigators require considerable modification; For example, the fact that Northern black men are less often at work than migrants has led to speculations about regional differences in work orientation among blacks, but a detailed analysis of labor force activity indicates this pattern does not hold for women. Likewise, the migrant income advantage is found to vary by education such that it is confined to those with low educational attainment. The use of sample tapes permits a novel analysis of differences between Northern-born blacks classified by whether they are second or at least third generation residents of the North (children of Southern- or Northern-born parents, respectively). For the attribute measured, school performance, the gap is essentially nil. Finally, an alternative is suggested to the existing causal interpretations of North-South gaps among black residents of the North. Reconsidered in particular are the higher labor force rates of migrant men and their more frequent employment in blue collar jobs; 相似文献

In contrast to the malaise that Collins (1986), characterized for sociology of the 1980s, I argue that the future for sociology
and sociologists is bright. There are three structural changes that lead to my optimism. First, the professoriate is changing
from one that has been overwhelmingly white, male, and tenured, to one that will become younger and more diverse by gender
and race. Second, the fiscal crisis of the state will limit monies for funded research, which will lead to more critical and
more qualitative research. Third, societal and global changes will present sociologists with unprecedented opportunities.
Globally, three momentous historical turning points present sociologists with incredible opportunities: (a) the shift to a
post cold war era; (b) the ecological crises threatening the worlds’s ecosystem; and (c) the transformation of the economy.
Within the United States, there are many contemporary trends with considerable sociological relevance: the aging of the baby
boom; the increasing proportion of the elderly; the growing racial/ethnic diversity; the regional shifts as the frost belt
loses population, resources, and power, while the sun belt gains; and the growing urban underclass that is being left further
and further behind. In short, the next two decades or so will present sociologists with exciting opportunities and challenges. 相似文献

It is a strong prior among many economists that unionized firms hire better-quality workers to offset higher union wages. In fact, standard economic theory does not support this prior. The key insights introduced by this paper are that, first, unions will likely raise future wages to reflect improvements in worker quality and, second, that unionized firms, anticipating this, often do better by hiring lower-quality workers. This surprising result has empirical support. 相似文献

This paper analyzes how authority can be maintained by structuring reality through continuous violent conflict. Using Lewis Coser's reformulation of Simmel's propositions on fostering continuous conflict as a raison d'être in sect-like struggle groups as a general frame of analysis, the Stalinist case is then examined in order to evaluate systematically these propositions in a societal context and to specify the morphology of violence as a method of conflict. By examining a societal context, it is noted that instability in the social structure not only can be a condition for the legitimacy of a problematic political leadership and system, but also simultaneously be a consequence of a form of preventive punitive sanctioning, whereby potential threats, both persons and alternative courses of action, are eliminated before they become present dangers. In turn, an official definition of reality, justifying leadership and system, is constructed through the public documentation of a conspiracy, which employs invented categories to demonstrate ideological continuity and fabricates pseudo events to demonstrate indispensability in fulfilling necessary functions. This public documentation of a conspiracy is then used as a facade for a larger plan of social prophylaxis that implicates the public as well as the police in ferreting out tangible and visible enemies to till the invented categories in the pseudo events. As public complicity conjoins with the official definition of reality, commitment to the leadership and system is acquired. 相似文献

A definition of the subject of statistics is given, and the difference between the chalkboard world of the teacher of statistics and the real world of the experimenter is stressed. An overemphasis on significance testing, hypothesis testing, and decision procedures has led to a de-emphasis of statistical design. The teaching of statistical design theory, statistics teaching in a changing world, the importance of model building, and different approaches to teaching statistics are discussed. Some published materials developed to meet teaching needs and a new type of statistics course are described. Information about special issues in statistical education (teaching and consulting) is presented. 相似文献

The American Statistical Association conducted a pilot study to develop methodology to conduct a nationwide evaluation of survey practices and the quality of survey data. This article is a report on the objectives and principal findings of that pilot study. In addition, the objectives of the nationwide study are presented. 相似文献

Unit-Root Tests and Asymmetric Adjustment With an Example Using the Term Structure of Interest Rates 总被引:1,自引:0,他引:1
This article develops critical values to test the null hypothesis of a unit root against the alternative of stationarity with asymmetric adjustment. Specific attention is paid to threshold and momentum threshold autoregressive processes. The standard Dickey–Fuller tests emerge as a special case. Within a reasonable range of adjustment parameters, the power of the new tests is shown to be greater than that of the corresponding Dickey–Fuller test. The use of the tests is illustrated using the term structure of interest rates. It is shown that the movements toward the long-run equilibrium relationship are best estimated as an asymmetric process. 相似文献

This paper is concerned with stochastic demand systems for continuous choices that arise from structural random utility models. It examines under which nonparametric conditions on the structural random utility specification the implied reduced form model is nonsingular and invertible. For parametric members within this class of random utility models, the paper provides conditions for local identification from the reduced form under moment assumptions. 相似文献
