We introduce two types of graphical log‐linear models: label‐ and level‐invariant models for triangle‐free graphs. These models generalise symmetry concepts in graphical log‐linear models and provide a tool with which to model symmetry in the discrete case. A label‐invariant model is category‐invariant and is preserved after permuting some of the vertices according to transformations that maintain the graph, whereas a level‐invariant model equates expected frequencies according to a given set of permutations. These new models can both be seen as instances of a new type of graphical log‐linear model termed the restricted graphical log‐linear model, or RGLL, in which equality restrictions on subsets of main effects and first‐order interactions are imposed. Their likelihood equations and graphical representation can be obtained from those derived for the RGLL models.  相似文献

This article describes the use of comparison theory to generate testable implications about demographic phenomena, and, to illustrate, derives some implications of comparison theory for migration behavior. Using two strategies for deriving predictions, known as the micromodel and macromodel strategies, we obtain a variety of theoretical results for the three types of actors in migration situations — the migrant, others in the origin country, and others in the destination country — for bilateral relations between origin and destination countries, and for the effects of the societal valued goods and the income distribution and its inequality on the differential propensity to emigrate among rich and poor.  相似文献

This paper broadens the approach of Hey and Lambert (Q. J. Econ. 95,567–573 1980) regarding relative deprivation to the case in which individuals compare themselves with individuals belonging not only to their own group, but also to other groups. In this way, we obtain the average deprivation of a population in relation to another. This allows us to establish a correspondence between the decomposition of the Gini coefficient based on a partition of the population, and the decomposition of deprivation into two components. One quantifies deprivation within the subpopulation and the other deprivation between populations. An empirical illustration is given, based on the European Community Household Panel (ECHP). The authors acknowledge the financial support of the Spanish Government–MCYT, (SEC2001-1668) and would like to thank Jacques Silber and two anonymous referees for their suggestions.  相似文献

Based on administrative and survey data as well as data-based assumptions about the bounds on alien address reporting, this study provides estimates of the lower and upper bounds for the cumulative net emigration rates, by country and area of origin, of the FY1971 cohort of legal immigrants to the United States as of January 1979. The merged data indicate that the cumulative net emigration rate for the entire cohort could have been as high as 50 percent. Canadian emigration was probably between 51 and 55 percent. Emigration rates for legal immigrants from Central America, the Caribbean (excluding Cuba), and South America were at least as high as 50 percent, and could have been as high as 70 percent. Emigration rates for Koreans and Chinese could not have exceeded 22 percent over the same period.  相似文献

This article explores contingency as a central yet underappreciated feature of care work. It does so by focusing on family elder care and the complex temporal interactions between caregiver, care receiver, and healthcare institutions in the U.S. context. Drawing on in‐depth interviews with 19 family caregivers for an elderly relative, I show that their experience of time is, paradoxically, systematically unpredictable. It is shaped by three dimensions: uncertain futures (not knowing how long, or how much, they will have to care), conflicting rhythms (mediating between the temporalities of institutions and that of the elderly relative), and flooded time (ongoing expectations of interruption). Focusing on caregivers’ experiences of unpredictability highlights their exclusion from broader social temporalities and the obstruction of their possibilities to craft their own futures. I therefore suggest that the experience and management of contingency may constitute its own form of inequality and is a fruitful site for exploring the temporal relations between paid and unpaid labor. Also, sociological theories of time and labor may benefit from foregrounding care work to advance understandings of the complex and hierarchical interactions between multiple temporal orders in post‐Fordist economies.  相似文献

The chief attraction of mathematics is its beauty. It is customary, nonetheless, to catalog the usefulness of mathematics. Accordingly, this paper shows how aspects of three quite different sociological problems—assortative mating and the rise of gender inequality, the sense of justice, and economic and political upheavals and societal transformations—have an identical underlying mathematical structure. Thus, progress in understanding the three sets of phenomena is linked; any new result obtained for one problem will shed light on the other two.  相似文献
