Migration disequilibrium and specific division rules

We examine the extent to which migration equilibria fail to exist in a global economy in which a specific division rule determines the allocation of a perfectly divisible, nondisposable resource among individuals with single-peaked preferences who reside in local economies. In particular, almost without exception, under the egalitarian, proportional, queuing, and uniform division rules, migration equilibria fail to exist for some sets of preferences.

Economic and other determinants of annual change in U.S. fertility: 1917-1976

Decomposition of fertility into its age, period, and cohort components demonstrates the empirical importance of age and period. Of the two, less is known about the period dimension. A new measure of fertility, specific to race and birth order, is used to estimate the effects of annual change in unemployment, the marriage and unemployment rate, as well as annual change in contraceptive sterilization and change in the proportion of couples adopting the more effective (pill and IUD) methods introduced in the early 1960s, are all important determinants of fertility change, but their impact varies greatly by birth order.     

Assumptions and Evidence Behind Sex Offender Laws: Registration, Community Notification, and Residence Restrictions

Since the mid-1990s legislators have enacted a series of laws regulating convicted sex offenders who have returned to communities. Policymakers crafted these laws to appease a worried public, but they were based on assumptions about sex offenders' behaviors that were not well supported by research evidence. In this paper we examine the social context within which these laws were passed and the assumptions behind the three most common sex offender laws – mandatory registration, community notification, and residence restrictions. Next we review the research that has been conducted so far to evaluate the effectiveness of these laws and their unintended consequences. We conclude with a discussion of the lessons learned from these sex offender laws for both policymaking and future research.     

The Roles of Love and Happiness in Divorce Decision Making

Little is known about divorce decision making, the process of deciding whether to divorce when a marriage is distressed. The focus of this qualitative study was to explore the roles of love and happiness—two Western ideals that govern contemporary marital processes—in divorce decision making. Married participants (N = 30) with recent thoughts about divorce were interviewed about their conceptions of love and happiness in their decision-making processes. The resulting categories for love included: (a) importance of love, (b) change over time, and (c) marital love. The categories for happiness included: (a) fluidity of happiness and (b) balancing happiness. Implications of the findings are discussed.     

The effects of a workplace intervention on employees’ cortisol awakening response

Work-related stressors are known to adversely affect employees’ stress physiology, including the cortisol awakening response (CAR) – or the spike in cortisol levels shortly after people wake up that aids in mobilizing energy. A flat or blunted CAR has been linked to chronic stress and burnout. This daily diary study tested the effects of a workplace intervention on employed parents’ CAR. Specifically, we tested whether the effects of the intervention on CAR were moderated by the type of days (workday versus non-work day). Data came from 94 employed parents from an information technology firm who participated in the baseline and 12-month diurnal cortisol components of the Work, Family, and Health Study, a group-randomized field experiment. The workplace intervention was designed to reduce work-family conflict (WFC) and implemented after the baseline data collection. Diurnal salivary cortisol was collected on 4 days at both baseline and 12 months. Multilevel modeling revealed that the intervention significantly increased employees’ CAR at 12 months on non-workdays, but this was not evident on workdays or for employees in the usual practice condition. The results provide evidence that the intervention was effective in enhancing employees’ biological stress physiology particularly during opportunities for recovery that are more likely to occur on non-work days.
