ASYMPTOTIC LIKELIHOOD APPROXIMATIONS USING A PARTIAL LAPLACE APPROXIMATION

Elimination of a nuisance variable is often non‐trivial and may involve the evaluation of an intractable integral. One approach to evaluate these integrals is to use the Laplace approximation. This paper concentrates on a new approximation, called the partial Laplace approximation, that is useful when the integrand can be partitioned into two multiplicative disjoint functions. The technique is applied to the linear mixed model and shows that the approximate likelihood obtained can be partitioned to provide a conditional likelihood for the location parameters and a marginal likelihood for the scale parameters equivalent to restricted maximum likelihood (REML). Similarly, the partial Laplace approximation is applied to the t‐distribution to obtain an approximate REML for the scale parameter. A simulation study reveals that, in comparison to maximum likelihood, the scale parameter estimates of the t‐distribution obtained from the approximate REML show reduced bias.     

Effects of Risk and Time Preference and Expected Longevity on Demand for Medical Tests

Despite their conceptual importance, the effects of time preference, expected longevity, uncertainty, and risk aversion on behavior have not been analyzed empirically. We use data from the Health and Retirement Study (HRS) to assess the role of risk and time preference, expected longevity, and education on demand for three measures used for early detection of breast and cervical cancer—regular breast self-exams, mammograms, and Pap smears. We find that individuals with a higher life expectancy and lower time preference are more likely to undergo cancer screening. Less risk averse individuals tend to be more likely to undergo testing.     

Hair loss and electability: The bald truth

This study probes one particular component of the well documented linkage between personal appearance and impression formation by investigating the extent to which and the mechanisms through which bald and balding men are underrepresented in high elective office. Study 1 compares the prevalence of hair loss among governors and members of Congress, on the one hand, and the general public, on the other, and concludes that officeholders are much more likely to have a full head of hair than would be expected of men of their age. Study 2 poses an experimental test of voter bias against bald and balding candidates by presenting voters in a simulated congressional race with materials depicting otherwise identical candidates in either their natural bald or balding condition or wearing a professionally fitted hairpiece. No voter bias against bald or balding candidates is apparent, a finding that suggests that the causal mechanism underlying underrepresentation of bald and balding men is not voter bias.Ugly is a field without grass, a plant without leaves, or a head without hair (Ovid, quoted by Klenhard, 1986, p. 11).Politics represents an area of public life in which the effects of appearance may lead to very important social consequences and in which the idea of special privilege for the pretty is particularly repellent (Efran and Patterson, 1975, p. 352).The authors thank Judee Burgoon, Michael Burgoon, and Carol Sigelman for useful comments and suggestions, and Brandt Baker, Henry Ewbank, Jeff Gardner, Henry Kenski, Dan Singer, and David Williams for their assistance with this project.     

Deviance,Rule-Breaking and Male Dominance in Conversation

Previous research on dyadic interaction indicates that cross-sex conversations (male-female) are characterized by more frequent interruptions than same-sex conversations. More specifically, males consistently tend to interrupt their female co-conversationalists. Survey data from three student samples suggest that normative definitions reflected in perceptions of interruption are inconsistent with the empirical distribution of rule-breaking observed by conversational researchers. These results provide some strategic insights into the problematic distinction between deviance and rule-breaking that has been central to labeling theory.     

Some responses to economic change in Scottish farming and crofting family life, 1900–25

Our investigation of some of the processes involved in the emergence of ‘the modern family’is based on evidence from oral histories conducted with people who grew up in Scottish farming and crofting families in the early decades of the century. After showing how peasant and capitalist modes of production shaped both family structures and strategies for getting a living, we examine some of the ways in which the encroachments of the cash economy helped create new forms of gendered inequalities. Our discussion concludes with an analysis of recent papers concerned with the ways in which families are embedded in community life and the implications for long term change in authority structures.     

Discourses of community: challenges for social work

The ambiguity of community allows it to be a space for a vast range of imposed and 'organic' social reproduction functions, and an accessible site for meaningful collective action, but it also has the potential for disempowerment. The breadth of the concept of 'community' allows for it to be critiqued as ephemeral or as romantic fiction, but also used and exploited by government. It is because it retains such power to evoke reaction and contest that we need to understand the power that drives it, and the ideological purpose for which it may be used or misused. The notion of discourse immediately becomes useful. We can recognise competing discourses of community, and examine how they are used politically. We can recognise ways in which social work can engage with community discourses of empowerment rather than control. The article will explore a number of discourses and examine their usefulness for practice.     

Policy, Preferences, and Patriarchy: The Division of Domestic Labor in East Germany, West Germany, and the United States

Individual agency observed in the gendered division of laboris shaped by structural factors, but only recently has evidenceemerged that the effect of women’s resources varies systematicallyin its sociopolitical context. Here we use the 1994 InternationalSocial Survey Program to assess whether the relative effectof a proxy for women’s and men’s preferences—hallmarkof individual choice—varies as well across three countrieswith divergent historical policy approaches regarding the privatesphere. East German socialist policies required and supportedwomen’s employment; West German policy promulgated a malebreadwinner model, and U.S. policy primarily remains silenton the private sphere. The division of domestic tasks and relativestrength of individual preferences on shifting it vary by region.In the former East Germany the division of domestic labor ismore egalitarian and the effect of preferences is small butequal for the genders. In West Germany the division is moretraditional and preference effects are greater, but gender differencesin these are insignificant. The U.S. division of domestic taskfalls between the two German regions, and the gender differencein preference effects is the greatest, with U.S. men’spreferences predicting significantly more variance than do U.S.women’s. Consequently, allowing the market to dominatedoes not yield equal strength of preferences in the individual-levelmodels used to predict the division of domestic tasks. Thissupports the dual-system feminist claims that capitalism canexacerbate nonmarket patriarchal hierarchies.     

The development of friendship in childhood: A clinical conversation

Our friendships are a way to think about meaning in life. Friendships are like protein, a psychological essential for growth and development. When we see two three-year-olds playing together at the park running, holding hands, laughing, we cannot help but be filled with a sense of joy and warmth We can view making friendships as a developmental process in itself. In this discussion, I will explore the use of toys as a means of making friends. I will also explore the psychological meaning of toys and how they are a developmental precursor to friendship. Two clinical examples will be given in which friendship was the predominant theme in the therapy.The author would like to thank the late Gary Davis for his enthusiasm and friendship.
