Assessing the Quality of Household Panel Data: The Case of the Panel Study of Income Dynamics

Evidence from a number of methodological studies are used to assess the overall quality of data from the Panel Study of Income Dynamics (PSID). Despite substantial cumulative non-response over the nearly two decades spanned by the study, the sample is found to maintain its representation of the nonimmigrant population of the United States. The most important reasons for this result are that the study's following rules insure that the sample replaces itself in the same manner as the population (through the formation of new families by the offspring of old) and that nonresponse is largely unsystematic. Nonresponse also appears to be largely random with respect to parameters in a number of behavioral models. The accuracy of measures is assessed by comparing survey measures with national aggregates and with highly accurate individual validating data. PSID reports of transfer income appear to compare more favorably with program aggregates than do reports from other large-scale surveys such as the Current Population Survey. Finally, although PSID survey measures generally are unbiased when compared to validating data, they contain amounts of measurement-error variance that range from trivially small to very large.

Abstract

While previous studies have used trust in the government as an exogenous variable to measure political protest and other forms of social unrest, we treat it as a dependent variable. Thus, we attempt to identify variables that affect trust in government, and we also distinguish between those variables that transcend race and those that differentially affect black and white respondents. Using data from the 1987 General Social Survey, we regress trust in the government on a variety of demographic and ideological measures. Results show that political apathy and belief that the government is unresponsive to the needs of the people lead to low levels of trust, regardless of the respondent's race. However, ideological variables such as political and religious views display different patterns for black and white respondents. While these variables do not affect black respondents' attitudes toward the government, they have a strong effect for white respondents. Implications of this study are discussed.     

舍勒的质料价值伦理与文化范式现象学

舍勒及其追随者哈特曼提出了质料价值伦理学说.该理论立足于现象学对西方伦理的形式主义、功利主义进行了深刻批判,主张对德性之立足根基的价值本身进行探察.价值的认知与价值的功能化滞后于价值洞见,而正是后者为前者提供了内容,或"质料".价值洞见从根本上发端于情感的家园--心灵,这一过程可以通过情感现象学得到理解.立足于情感现象学,舍勒提出了不同文化背景的人能够探察异质文化价值之根基,从而同情、容忍直至接受异己文化范式,最终实现世界文化与文明的"谐调".舍勒的思想能够在佛教学说中得到回应.     

Qualitative Risk Assessment of the Acquisition of Meticillin‐Resistant Staphylococcus aureus in Pet Dogs

This article presents a qualitative risk assessment of the acquisition of meticillin‐resistant Staphylococcus aureus (MRSA) in pet dogs, representing an important first step in the exploration of risk of bidirectional MRSA transfer between dogs and humans. A conceptual model of the seven potential pathways for MRSA acquisition in a dog in any given 24‐hour period was developed and the data available to populate that model were considered qualitatively. Humans were found to represent the most important source of MRSA for dogs in both community and veterinary hospital settings. The environment was found to be secondary to humans in terms of importance and other dogs less still. This study highlights some important methodological limitations of a technique that is heavily relied upon for qualitative risk assessments and applies a novel process, the use of relative risk ranking, to enable the generation of a defensible output using a matrix combination approach. Given the limitations of the prescribed methods as applied to the problem under consideration, further validation, or repudiation, of the findings contained herein is called for using a subsequent quantitative assessment.     

Welfare and the Children of Immigrants: Transmission of Dependence or Investment in the Future?

The public concern that immigrant families might be using a disproportionate share of social benefits and transmitting some form of public dependency to their children, combined with the rising levels of immigrants entering the country, fueled the passage of the Personal Responsibility and Work Opportunity Reconciliation Act in 1996, which limited public assistance to many immigrant families. This paper uses the National Longitudinal Survey of Youth 1997 to explore the association between exposure to welfare and young adult outcomes of high school graduation, college enrollment and labor force participation with a focus on parental nativity status as well as broad country of origin group. Results indicate a persistent negative association between welfare legacy and high school graduation; a negative association that is most pronounced for children of natives. Results also show the largest positive effect of welfare receipt among the most disadvantaged group, the young adult children of immigrants from Mexican and Central American countries. The main finding of this study suggests that the negative impacts of welfare receipt might be lessened and in some cases reversed among the young adults from immigrant families. Such findings challenge the common notion that immigrant families use welfare as a crutch across generations and raise serious concern about U.S. immigration and welfare policies.     

Dynamic Equicorrelation

A new covariance matrix estimator is proposed under the assumption that at every time period all pairwise correlations are equal. This assumption, which is pragmatically applied in various areas of finance, makes it possible to estimate arbitrarily large covariance matrices with ease. The model, called DECO, involves first adjusting for individual volatilities and then estimating correlations. A quasi-maximum likelihood result shows that DECO provides consistent parameter estimates even when the equicorrelation assumption is violated. We demonstrate how to generalize DECO to block equicorrelation structures. DECO estimates for U.S. stock return data show that (block) equicorrelated models can provide a better fit of the data than DCC. Using out-of-sample forecasts, DECO and Block DECO are shown to improve portfolio selection compared to an unrestricted dynamic correlation structure.     

Twelve Years After: The Berlin Wall as Will and Idea

The Berlin Wall at different times in its ignominious history has been demonized by Western opinion less because of its real paltry role in the Cold War tension in Europe than because of the fears and frustrations it generated within Europe. This is the central theme and claim of this paper. We attempt to show through an excursion of personal and institutional events how the perceptions of Soviet communist realities were refracted through the icon of the Wall as a Cold War symbol.     

Public Sociology: Working at the Interstices

The article examines recent debates surrounding public sociology in the context of a UK based Department of Applied Social Sciences. Three areas of work within the department form the focus of the article: violence against women and children; community-based oral history projects and health ethics teaching. The article draws on Micheal Burawoy’s typology comprising public, policy, professional and critical sociology, and argues that much of the work described in the case studies more often lies somewhere in between, in the interstices, rather than within one or other of the four types. The result is not without its tensions and dilemmas, some of which are identified and explored, notably those arising from attempts to appeal to diverse audiences and meet the sometimes conflicting expectations of each.     

Whose Wishes and Feelings? Children's Autonomy and Parental Influence in Family Court Enquiries

The importance of the child’s right to be heard and fortheir wishes and feelings to be taken notice of is now acceptedacross a broad professional and research terrain. Increasingly,children are being treated as active participants in the processesand decisions that affect them. In cases of divorce and separation,especially where parental relationships are conflicted, theaccepted wisdom in the UK for many years has been for childrento be protected rather than empowered. More recently, practitioners,policy makers and researchers have looked for ways to involvechildren, although the ‘welfare’ of the child hasremained paramount. In this context, the question of how toensure that wishes and feelings expressed are those that authenticallybelong to the child, rather than to their parent, sibling orother, has achieved a new significance. This article presentsfindings from recent research to illustrate how the tensionbetween protection and empowerment is being played out in thisaspect of welfare report enquiries carried out by CAFCASS (Childrenand Family Court Advisory and Support Service) private law practitioners.
