Health and medical services use: a matched case comparison between CCRC residents and national health and retirement study samples

Little is known about the health status of adults living in continuing care retirement communities (CCRC). Using matched-case control, 458 adults from the Health and Retirement Study (HRS) or a CCRC-based sample were compared on total comorbidity, self-rated health, home health services use, and hospitalizations. At year 2, the CCRC sample reported more comorbidities (96%) but significantly better self-rated health (96% good/excellent) than the HRS sample (93% comorbidity, 73% good/excellent; p < .01). There were no significant differences in frequency of home health use or hospitalization. Living in a CCRC appears to be associated with higher self-ratings of health in this sample.     

The New Zealand Refugee Resettlement Strategy: implications for identity,acculturation and civic participation

The process of resettlement as a refugee often involves adapting to, and reconciling with, a new social reality. The complexities associated with acculturation across age, gender and family dynamics are navigated within greater social contexts that may encourage or hinder the processes of adjustment and settlement. This paper addresses the recent New Zealand Refugee Resettlement Strategy in light of contemporary theoretical developments with regard to the segmented assimilation thesis and the forms of social capital that, when available, may be mobilised to help refugee-background individuals, families and communities to forge new routes for participation and belonging. In particular, we examine the strategy and its five main goals of self-sufficiency, participation, health and well-being, education and housing as these relate to the possibilities and tensions at play in the wider acculturation experiences of New Zealand's diverse refugee populations.     

Marriage, divorce, and legal change: new evidence from England and Wales

In this article, we explain the evolution of divorce rates in England and Wales over the post-war period. Following the approach of the predominantly North American literature in this area, we focus on the liberalization of divorce law and socioeconomic factors as determinants of the divorce rate. In line with the development of the literature, we find that the introduction of liberalized, no-fault divorce law had a significant effect on the divorce rate in England and Wales. The finding that the law affects the divorce rate is consistent with the view that marriage is characterized by indivisibilities that inhibit Coasian bargaining.     

A theory of quality-related differences in retail margins: why there is a 'premium' on premium gasoline

This paper develops a theory of vertical and horizontal product differentiation to explain observed price-cost margin differentials for goods that differ in quality. The difference in price-cost margins between the high- and low-quality goods is shown to depend positively on consumers' average valuation for incremental increases in quality and positively on the distance to each competitor's closest rival. These predictions are largely supported using an extensive station-level data set of premium and regular unleaded gasoline prices from the Los Angeles Basin area from 1992–1995.     

On the limits of generalizability: applying resource exchange theory to gay relationship processes

In the present studies, we examined patterns of interpersonal resource exchange (E. B. Foa & U. G. Foa, 1980; U. G. Foa & E. B. Foa, 1974) among gay male and female couples. Study 1 was quantitative in nature, whereas Study 2 was qualitative in nature. In Study 1 (n's = 61 male couples and 54 female couples), we explicitly tested the hypotheses that partners in same-sex romantic relationships would exchange affection and respect positively and significantly; results indicated that affection (but not respect) was exchanged or reciprocated positively and significantly among gay male (but not gay female) pairs. In Study 2 (n's = 15 male couples and 15 female couples), we asked the research question, but did not test any formal hypotheses, as to whether same-sex romantic pairs would spontaneously invoke interpersonal resource exchange and other reinforcement processes when describing their relationships; results indicated that gay female (but not gay male) couples appeared to adopt a communal, rather than exchange, orientation toward their relationships with regard to displays of affection. Implications for the study of relationship processes among same-sex romantic pairs are discussed.     

Tests for homogeneity of variance

Six procedures which convert tests of homogeneity of variance into tests for mean equality for independent groups are compared. The tests are the analysis of variance (ANOVA) and Welch F statistics. The Welch statistics are included since it was anticipated that ANOVA would not provide a robust test when samples of unequal sizes are obtained from non-normal populations. However, the Welch tests are not found to be uniformly preferrable. In addition, a prior recommendation for Miller's jackknife procedure is not supported for the unequal sample size case. The data indicates that the current tests for variance heterogeneity are either sensitive to non-normality or, if robust, lacking in power. Therefore, these tests cannot be recommended for the purpose of testing the validity of the ANOVA homogeneity assumption.     

Conditional Score Tests for Heteroscedasticity in the Two-Way Error Components Model

This paper extends the one-way heteroskedasticity score test of Holly and Gardiol (2000, In: Krishnakumar, J, Ronchetti, E (Eds.), Panel Data Econometrics: Future Directions, North-Holland, Amsterdam, pp. 199–211) to two conditional Lagrange Multiplier (LM) tests of heteroskedasticity under contiguous alternatives within the two-way error components model framework. In each case, the derivation of Rao's efficient score statistics for testing heteroskedasticity is first obtained. Then, based on a specific set of assumptions, the asymptotic distribution of the score under contiguous alternatives is established. Finally, the expression for the score test statistic in the presence of heteroskedasticity and related asymptotic local powers of these score test statistics are derived and discussed.     

Supporting older youth: what's policy got to do with it?

The nonschool hours are an underused tool in supporting older youth in their transition to adulthood. Given competing demands on many teens' time and a host of other developmental realities, effective strategies for engaging high schoolers look much different from those of their younger counterparts, and those differences have programmatic and policy implications. Effective youth policies reflect an overarching vision that is about changing lives--a vision that addresses a range of risk and protective factors, simultaneously supports discrete programs and builds coherent pathways to success, and recognizes that children and youth grow up in families and communities. This chapter highlights policy innovations related to teens' involvement in out-of-school-time activities and then looks at three principles that can help ensure that youth policy supports the full range of older youth's unique developmental, social, and economic needs.
