Temperament and the Development of Conscience: The Moderating Role of Effortful Control

In this longitudinal study we examined whether two components of effortful control, behavioral control, and executive function moderated the relation between temperament and conscience development. Temperament was assessed when participants were two years of age, and three temperament groups were formed: inhibited, exuberant, and low reactive. At 4.5 years of age, children's behavioral control and executive function were assessed. Moral behavior, emotionality during an empathy film, and false-belief understanding were measured at 5.5 years of age as components of conscience. Results indicate that inhibited children may benefit most from higher levels of effortful control. Inhibited children with higher levels of behavioral control performed better on false-belief understanding tasks whereas inhibited children who scored higher on executive function tests reported less emotional response to the evocative film. Finally, as a group, inhibited children exhibited more moral behavior than exuberant and low reactive children.     

Visual Sequence Learning in Infancy: Domain-General and Domain-Specific Associations with Language

Research suggests that non-linguistic sequence learning abilities are an important contributor to language development (Conway, Bauernschmidt, Huang, & Pisoni, 2010). The current study investigated visual sequence learning as a possible predictor of vocabulary development in infants. Fifty-eight 8.5-month-old infants were presented with a three-location spatiotemporal sequence of multi-colored geometric shapes. Early language skills were assessed using the MacArthur-Bates CDI. Analyses of children's reaction times to the stimuli suggest that the extent to which infants demonstrated learning was significantly correlated with their vocabulary comprehension at the time of test and with their gestural comprehension abilities 5 months later. These findings suggest that visual sequence learning may have both domain-general and domain-specific associations with language learning.     

Passion,Intimacy, and Commitment in Casual Sexual Relationships in a Canadian Sample of Emerging Adults

Research on casual sexual relationships (CSRs) among emerging adults is prevalent, yet our empirical and theoretical knowledge of relationship processes involved in these relationships is limited. The present study’s objective was to compare four CSR partner types (acquaintance, friend, non-dating partner, ex-romantic partner) on passion, intimacy, and commitment, the components of Sternberg’s triangular theory of love. A total of 441 Canadians aged 18–25 years who were not in a romantic relationship, and who reported having had more than one sexual contact with their last CSR partner, completed an online survey. Across all partner types, passion was highest, followed by intimacy and commitment. Levels of passion, intimacy, and commitment generally increased with partner familiarity. However, CSR partner type differences on the three components were partially explained by CSR components (i.e., frequency of sexual activity, frequency of social activity, whether partners saw each other with the main goal of having sex, sexual exclusivity agreement, and hopes about the relationship). Results are consistent with CSRs’ emphasis on sexuality, and, to a lesser extent, emotions. However, they challenge the mainstream and scientific conflation of CSRs with an absence of emotional bond, commitment, or love.     

Estimating the Structure of Agricultural Investment: A Stochastic- Coefficients Approach

Two approaches, a flexibie-accelerator model and a stochastic-coefficients alternative, are used to estimate the structure of aggregate agricultural investment. Structural estimates of the adjustment rates for each model differ. The stochastic-coefficients model, however, performs better in out-of-sample forecasting.     

The foundations of econometrics-are there any

The conclusions of alogically consistent economic theory which strictly adheres to Aristotle's axioms of logic are factually true if its sufficient conditions are all factually true. Alternatively, if a conclusion of such a theory is false, then at- least one of its assumptions is false. Unfortunately, the factual truth of sufficient conditions cannot be established because the problem of induction i s impossible t o solve. It is algo true that the falsity of a conclusion cannot be established in the presence of uncertainty. While the philosophy of instrumentalism applied to sufficient and logically consistent explanations may provide useful solutions to immediate practical problems, the principles of simplicity, parsimony and profligacy--all of them requiring conditional deductive arguments--are useless as criteria for model choice.     

Does Child Gender Predict Older Parents’ Well-Being?

Inconsistencies in comparisons of older parents’ well-being with that of older, childless adults may be resolved by considering the separate effects of sons and daughters on parents. The hypothesis was that older parents of only daughters have greater life satisfaction, more satisfying relations with their children, more intimate family relations, and greater social support satisfaction compared to older childless adults and parents of only sons. Childless older adults were predicted to have more intimate friends. The effect of having both sons and daughters was also explored. Longitudinal results indicated parents had greater life satisfaction than childless adults, and parents of daughters were more satisfied with relations with their children than parents of only sons. Childless adults had more relations with friends and fewer family intimate relations. Neither social support satisfaction or affect varied across groups. The findings are related to gender socialization, social support, and normative expectations.     

Out with the Old,In with the Old: A Closer Look at Younger Versus Older Elderly Migration*

Objective. This research examines the migration behavior of the elderly, recognizing that the older and younger elderly may make different decisions and have different consequences for the states in which they live. Methods. Using U.S. Census migration flow data, we describe the movements of the younger and older elderly. Our econometric analysis brings together the wisdom of elderly migration research that focuses on motives (amenity vs. return/assistance) and the Tiebout‐related research that considers the effects of policy. Results. We find that all elderly age groups avoid moving to states with high estate/inheritance/gift taxes, although the effect weakens with age. Likewise, the younger elderly appear to be “shopping around” for destinations with a temperate climate and favorable government policies regarding income taxes and welfare spending, whereas the older elderly are more likely to be “driven out” of their origin state by a high cost of living and income and property taxes. Conclusions. Our findings suggest that both the patterns of migration and the factors that affect migration decisions differ between the younger and older elderly.     

Saving Open Spaces: Determinants of 1998 and 1999 "Antisprawl" Ballot Measures

Objective. Although such measures received media attention as indicative of a nationwide rebellion against sprawl, determinants of the appearance and success of 1998 and 1999 open-space preservation ballot measures have not been investigated. We suspect that, contrary to assumptions, these are not triggered by sprawled development and represent a response limited to small, wealthy communities. Methods. The influence of population density, total population, percentage of Anglos, and median income on these initiatives is estimated through regression. Results. Low population density is not the trigger for the appearance and passage of these measures; however, demographic factors determinant of limits on growth in general do exhibit significant influence. Conclusions. The 1998 and 1999 open-space measures are better explained by the broad "growth machine" approach than they are by popular assumptions of what prompted these policies. In short, the existence of sprawl lacks a positive empirical link to its putative solution.     

A case–control study relating railroad worker mortality to diesel exhaust exposure using a threshold regression model

A case–control study of lung cancer mortality in U.S. railroad workers in jobs with and without diesel exhaust exposure is reanalyzed using a new threshold regression methodology. The study included 1256 workers who died of lung cancer and 2385 controls who died primarily of circulatory system diseases. Diesel exhaust exposure was assessed using railroad job history from the US Railroad Retirement Board and an industrial hygiene survey. Smoking habits were available from next-of-kin and potential asbestos exposure was assessed by job history review. The new analysis reassesses lung cancer mortality and examines circulatory system disease mortality. Jobs with regular exposure to diesel exhaust had a survival pattern characterized by an initial delay in mortality, followed by a rapid deterioration of health prior to death. The pattern is seen in subjects dying of lung cancer, circulatory system diseases, and other causes. The unique pattern is illustrated using a new type of Kaplan–Meier survival plot in which the time scale represents a measure of disease progression rather than calendar time. The disease progression scale accounts for a healthy-worker effect when describing the effects of cumulative exposures on mortality.     

Issue Framing and Citizen Apathy Toward Local Environmental Contamination

We adapt the frame-alignment perspective in order to demonstrate how institutional framing shapes media coverage of a toxic crisis. This framing activity is described as a new approach to managing public responses to contamination that differs from the approach characterizing contamination episodes at Love Canal and Woburn, MA. Our analysis focuses on the process by which actors responsible for managing toxic crises carefully construct and manage a coordinated risk frame. We refer to this as institutional framing and illustrate how it shapes media framing of a toxic event. We conclude by proposing further research to identify the causal relationship between institutional framing and the absence of mobilization.
