Unweaving leaving: the use of models in the management of employee turnover

This paper offers a review of the literature on labour turnover in organizations. Initially, the importance of the subject area is established, as analyses of turnover are outlined and critiqued. This leads to a discussion of the various ways in which turnover and its consequences are measured. The potentially critical impact of turnover behaviour on organizational effectiveness is presented as justification for the need to model turnover, as a precursor to prediction and prevention. Key models from the literature of labour turnover are presented and critiqued.     

The primary-goods indexation problem in Rawls's theory of justice

Rawls's Difference Principle holds that basic social institutions are just if they maximize the worst-off individual's potential welfare, which depends on the vector of amounts of primary goods. As Rawls recognized, the multiplicity of primary goods poses an index number problem. This paper uses the machinery of social choice to characterize the class of procedures for aggregating quantities of several primary goods into a composite ordinal index that are consistent with Rawls's analysis. Only very simple and unattractive aggregation methods in which the various primary goods play roles of radically different magnitudes are compatible with Rawls's argument.     

Parental sensitivity and friendship development: The mediating role of cooperation

Interactions with mothers and fathers form a critical foundation for youths’ later peer relationships. This study focused on the associations of maternal and paternal sensitivity in third grade with friendship outcomes in sixth grade. Because interactions with parents provide the earliest opportunities for children to learn prosocial behaviors such as cooperation, and cooperation is theoretically conceptualized as a foundation of friendship, cooperation may play a role in the link between parenting and children’s later social relationships. Using the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development sample (N = 955; 51% female; 83% White), and a multimethod, multireporter longitudinal design, children’s cooperation was tested as a mediating mechanism that linked parental sensitivity to early adolescent friendship. Results indicated that most indirect paths from both mothers and fathers’ sensitivity to observed friendship interactions and perceived friendship quality, via cooperation, were significant. Findings provide a more concrete understanding of how parental sensitivity translates to better friendships.     

Neurobehavioral Consequences of Prenatal Exposure to Smoking at 6 to 8 Months of Age

Between 400,000 and 800,000 infants are born in the United States each year to women who smoked cigarettes during their pregnancy. Whereas the physical health consequences to infants of prenatal exposure to smoking are well established, the early neurobehavioral consequences are less well understood. This study investigated the neurobehavioral consequences of prenatal exposure to smoking using an epidemiologically derived sample of 454 infants who were drawn from a larger sample of 1,292 infants whose families were recruited at birth. Results indicated that, on average, infants who were exposed to higher levels of prenatal smoking exhibited less positive affect and greater irritability. Moreover, among male infants, elevated levels of prenatal exposure to smoking were associated with lower levels of approach, gross motor movement, reactivity, and attention. There was no evidence that the effects of prenatal exposure to smoking on infant neurobehavioral functioning were mediated by physical growth parameters (infant weight and head circumference) that are also known to be affected by prenatal exposure to smoking.
