We test whether young adults who co‐reside with their parents derive influence over household‐level expenditure by earning income. We propose a new variant of the Engel curve consistent with the Quadratic Almost Ideal Demand System, which allows a simple test of income pooling. Our tests suggest that young adults and parents mostly pool their income — pooling is not rejected for 8 out of 12 expenditure categories. We are more likely to reject income pooling between young adults and their parents in those expenditure categories where the model fit is highest, so our results may be interpreted as an upper bound on income pooling. We also apply our tests to income pooling between husbands and wives and find that pooling holds for 9 out of 12 expenditure categories. We find the opposite relationship with fit — expenditure categories where fit is poor are those where we are most likely to reject income pooling.  相似文献

Abstract

Form subdivision may be defined as the extension of a subject heading based on the form or arrangement of the subject matter in the book. In other words, it repre sents what the book is, rather than what it is about, the subject matter being expressed by the main heading.1 David Judson Haykin, Subject Headings: A Practical Guide (Washington, D.C.: GPO, 1951).1  相似文献

Abstract

In 1999, the California Digital Library (CDL) began a new cooperative venture, the Shared Cataloging Program, to improve access to its growing collection of electronic resources. Now known within the University of California (UC) as the SCP, the Shared Cataloging Program, based at UC San Diego, distributes ready-to-use cataloging records for all electronic titles licensed by the CDL to each of the other eight (soon to be nine) physical UC campuses. The SCP is the result of an intensive systemwide planning process fostered by a desire for an innovative approach to providing traditional bibliographic access to large numbers of electronic resources. It was launched out of pragmatic necessity along with an institutional commitment to the cooperative ideals of labor-savings, experimentation, and the search for “best practices.” This article will describe its genesis, current operation, one library's use of the records, and issues for future development.

Objective. I examine the association between total time on welfare and recipients' college attendance and graduation over a 20‐year period. Methods. Using data from the National Longitudinal Survey of Youth, I model the determinants of college enrollment and graduation among welfare recipients, and the association between the total number of months a recipient receives aid and her college attendance and graduation. Models examine separately the effects associated with longer stays on aid while recipients attend school as well as reduced recidivism associated with college attendance and graduation. Results. Findings indicate that attending college is associated with more months on aid, but graduating largely offsets this increase through reductions in return to aid. Conclusions. Policymakers' concerns that including postsecondary education as a TANF activity would undermine the short‐term focus of the program are not fully supported. A greater concern is the low rate of graduation among welfare recipients, who reap the most benefits from college attendance and sacrifice the fewest months on aid.  相似文献

Abstract Previous studies have established that community residents and leaders differ in their support for hazardous waste facility siting in rural areas (Spies et al. 1998). We examine whether these same differences exist in rural communities that face other high‐risk development decisions by analyzing resident and leader support for a proposed gold cyanide process (GCP) mine in Montana. Compared to proposed hazardous waste facilities, a much stronger predictor of both resident and leader support in the GCP mine context is recreancy, or distrust in institutions and outside interveners. However, perceived economic benefits remain key differences between residents and leaders in both the GCP mine and hazardous waste facility cases.  相似文献

Much has been written to explain the collapse of the former Soviet Union. Little attention, however, has been paid to understanding why post-1991 Russia has maintained stability despite continued economic and political turmoil throughout the 1990s. This paper attempts to answer this question by applying an integrated model of territorial disintegration to examine the political, economic, demographic, and geopolitical changes in the pre-1991 Soviet Union and post-1991 Russia. The integrated model is constructed by synthesizing Goldstone's demographic-structural model, Skocpol's and Collins' geopolitical model, and a modified version of Collins' argument of the destabilizing potential brought about by rapid market development as three alternative routes to territorial disintegration. It is found that improvement in Russia's geopolitical condition after 1991 is largely responsible for the decline in disintegrative potential. Slower population growth also rendered the demographic route less disintegrative during the 1990s. More effective taxation and the availability of foreign loans enabled the Russian state to handle its financial crises, thereby curbing the development of destabilizing forces through the dynamics proposed by Collins.  相似文献

This study investigated whether acoustic input, in the form of infant‐directed speech, influenced infants' segmenting of action sequences. Thirty‐two 7.5‐ to 11.5‐month‐old infants were familiarized with video sequences made up of short action clips. Narration coincided with portions of the action stream to package certain pairs of clips together. At test, packaged and nonpackaged pairs of actions were presented side by side in silence. Narration heard during familiarization influenced how infants viewed the action units, such that at test, infants older than 9.5 months (but not younger) looked longer at the nonpackaged than the packaged action sequences. The role of infant‐directed speech as well as other types of acoustic input in assisting infants' processing of action is discussed.  相似文献

Abstract Community satisfaction has often been linked to the level of satisfaction with a community's infrastructure, job opportunities, and social support networks. Yet most empirical analyses of community satisfaction have focused on only one aspect of the available theory to predict community satisfaction. In this paper we integrate multiple models to analyze community satisfaction of almost 4,000 rural Nebraskans. The integrated model indicates that social ties may have a greater role in predicting community satisfaction than had been thought previously.  相似文献
