Becoming Self-Employed

This study explored how persons become self-employed. In critical incident interviews (Flanagan, 1954) with 5 self-employed persons, the critical events that assisted or hindered progress toward self-employment were elicited in chronological order. First, the 108 incidents were organized into 22 categories. Next, using the chronological order of categories of events, 2 basic patterns or plots for becoming self-employed were identified. Last, 8 distinctive themes of personal progress in the patterns were described. In general, becoming self-employed involved establishing conditions of action that enhanced a sense of agency, enabling each person to make a decision.     

Minority Stress and Stress Proliferation Among Same‐Sex and Other Marginalized Couples

Drawing from 2 largely isolated approaches to the study of social stress—stress proliferation and minority stress—the authors theorize about stress and mental health among same‐sex couples. With this integrated stress framework, they hypothesized that couple‐level minority stressors may be experienced by individual partners and jointly by couples as a result of the stigmatized status of their same‐sex relationship—a novel concept. They also consider dyadic minority stress processes, which result from the relational experience of individual‐level minority stressors between partners. Because this framework includes stressors emanating from both status‐based (e.g., sexual minority) and role‐based (e.g., partner) stress domains, it facilitates the study of stress proliferation linking minority stress (e.g., discrimination), more commonly experienced relational stress (e.g., conflict), and mental health. This framework can be applied to the study of stress and health among other marginalized couples, such as interracial/ethnic, interfaith, and age‐discrepant couples.     

The Impact of Family Transitions on Child Fostering in Rural Malawi

Despite the frequency of divorce and remarriage across much of sub-Saharan Africa, little is known about what these events mean for the living arrangements of children. We use longitudinal data from rural Malawi to examine the effects of family transitions on the prevalence and incidence of child fostering, or children residing apart from their living parents. We find that between 7 % and 15 % of children aged 3–14 are out-fostered over the two-year intersurvey period. Although divorce appears to be a significant driver of child fostering in the cross-sectional analysis, it is not significantly associated with the incidence of out-fostering. In contrast, maternal remarriage has both a lagged and an immediate effect on the incidence of out-fostering. Furthermore, the likelihood of out-fostering is even higher among children whose mother remarried and had a new child during the intersurvey period. Using longitudinal data collected from living mothers rather than from children’s current foster homes offers new insights into the reasons children are sent to live with others besides their parents.     

Political Orientations and Naturalization Among Latino and Latina Immigrants*

Objective. This study adds to our knowledge of the naturalization process by considering the impact of political orientations in shaping the pursuit of U.S. citizenship among contemporary Latino and Latina immigrants. Methods. We draw on data from the 1999 Harvard/Kaiser/Washington Post “Latino Political Survey” and use ordered logistic regression analyses to test the effects of political orientations on immigrant naturalization. Results. Political orientations exert a powerful influence on naturalization beyond the traditional sociodemographic determinants. Furthermore, the impact of political orientations on naturalization varies by gender. Conclusions. Naturalization can be induced by stressing the importance of voting and being interested in politics. In addition, Latinas are more likely to pursue naturalization than Latinos and the factors driving their decisions systematically differ from those of their male counterparts.     

General equilibrium with information sales

Consider a general equilibrium model in which information is an indivisible differentiated commodity for which satiation occurs at one unit. Suppose that uncountably many types of information are possible which can be costlessly combined by agents who desire information only because it helps them to maximize state dependent utilities under uncertainty. Similarity of information is expressed by a metric which reflects substitution possibilities among different information structures. Such a large pure exchange economy in which prices for (differentiated) information structures and (finitely many) ordinary commodities are determined simultaneously is consistent - equilibrium distributions exist.     

Using the integrative model of behavioral prediction to understand college students’ STI testing beliefs,intentions, and behaviors

ABSTRACT

Objectives: To identify salient behavioral determinants related to STI testing among college students by testing a model based on the integrative model of behavioral (IMBP) prediction. Participants: 265 undergraduate students from a large university in the Southeastern US. Methods:Formative and survey research to test an IMBP-based model that explores the relationships between determinants and STI testing intention and behavior. Results: of path analyses supported a model in which attitudinal beliefs predicted intention and intention predicted behavior. Normative beliefs and behavioral control beliefs were not significant in the model; however, select individual normative and control beliefs were significantly correlated with intention and behavior. Conclusions: Attitudinal beliefs are the strongest predictor of STI testing intention and behavior. Future efforts to increase STI testing rates should identify and target salient attitudinal beliefs.     

Revisiting the stock price impact of quality awards

In an event study, Hendricks and Singhal [Hendricks KB, Singhal VR. Quality awards and the market value of the firm: an empirical investigation. Management Sci 1996;42:415–36.] find evidence that firms that win quality awards are further rewarded with a stock price increase on the day of the award announcement. We revisit Hendricks and Singhal (1996), extend their research and find four reasons why management, owners and analysts should be cautious about expecting an abnormal return when a firm wins a quality award. First, in our sample of Baldrige Award winners, the evidence of a stock price response on the announcement day is only marginally significant. Second, in our sample of State quality award winners, the announcement day relationship between stock returns and winning awards is not significant. Third, in the most recent subperiod, 1992–1997, we find no evidence of positive abnormal returns. Fourth, the marginally significant Baldrige results are actually driven by just four companies. A company-by-company microanalysis reveals that only 50% of the award winners experienced positive abnormal returns. The diminishing stock price response on event day does not necessarily imply a lack of stockholder rewards. Evidence from other studies suggests that the stockholders are rewarded for successful total quality management (TQM) implementation, but the rewards can come long before and after the formal award is presented. From a shareholder value perspective, TQM still matters but the award ceremonies may not.     

Bayesian palaeoclimate reconstruction

Summary.  We consider the problem of reconstructing prehistoric climates by using fossil data that have been extracted from lake sediment cores. Such reconstructions promise to provide one of the few ways to validate modern models of climate change. A hierarchical Bayesian modelling approach is presented and its use, inversely, is demonstrated in a relatively small but statistically challenging exercise: the reconstruction of prehistoric climate at Glendalough in Ireland from fossil pollen. This computationally intensive method extends current approaches by explicitly modelling uncertainty and reconstructing entire climate histories. The statistical issues that are raised relate to the use of compositional data (pollen) with covariates (climate) which are available at many modern sites but are missing for the fossil data. The compositional data arise as mixtures and the missing covariates have a temporal structure. Novel aspects of the analysis include a spatial process model for compositional data, local modelling of lattice data, the use, as a prior, of a random walk with long-tailed increments, a two-stage implementation of the Markov chain Monte Carlo approach and a fast approximate procedure for cross-validation in inverse problems. We present some details, contrasting its reconstructions with those which have been generated by a method in use in the palaeoclimatology literature. We suggest that the method provides a basis for resolving important challenging issues in palaeoclimate research. We draw attention to several challenging statistical issues that need to be overcome.
