Multiracial Identities and Employee Absenteeism: Testing Contact and Depletion Hypotheses

Employee absenteeism costs the U.S. economy billions of dollars each year. Recent research finds that workplace characteristics are important predictors, yet variation remains by racial identity. Less is known about the reasons multiracial workers miss work. With data from the 2014 General Social Survey, we test a contact hypothesis and a depletion hypothesis. The findings support the depletion hypothesis. Multiracial workers are likely feeling cognitively taxed from comparatively more interracial interaction in the workplace, resulting in their higher rate of employee absenteeism. Given that the number of multiracial individuals living and working in the United States is expected to grow substantially over the next decade, understanding the factors that explain their work behavior may be beneficial to all social groups.     

The intergenerational transmission of income mobility between mothers and their young adult daughters: The mediating role of their daughters' educational attainment

This study examines whether the daughters' educational attainment mediates the intergenerational transmission of economic mobility between mothers and their young adult daughters. To create mother–daughter dyads, two data sets were combined: The National Longitudinal Survey of Youth 1979 (NLSY79) and the National Longitudinal Survey of Youth 79 for Children and Young Adults (NLSY79 CY). A total of 2,456 dyads were included for analysis. We used a mediation model to explore the relationship between mothers' income and their young adult daughters' income. Mothers' income was associated with their young adult daughters' educational attainment and income. The mediation model indicated partial mediation of the relationship between mothers' income and their young adult daughters' income via their young adult daughters' educational attainment. Addressing issues of income inequality among mothers may serve as a buffer against the low upward mobility across generations for their young adult daughters raised by low-income mothers. It is imperative to provide programs and financial assistance for mothers to bolster their income and thereby their daughters' educational attainment and income in young adulthood and therefore improve economic mobility from mothers to daughters.     

Principles for Conduct of Pest Risk Analyses: Report of an Expert Workshop

The North American Free Trade Agreement (NAFTA) and the General Agreement on Tariffs and Trade (GATT) have focused attention on risk assessment of potential insect, weed, and animal pests and diseases of livestock. These risks have traditionally been addressed through quarantine protocols ranging from limits on the geographical areas from which a product may originate, postharvest disinfestation procedures like fumigation, and inspections at points of export and import, to outright bans. To ensure that plant and animal protection measures are not used as nontariff trade barriers, GATT and NAFTA require pest risk analysis (PRA) to support quarantine decisions. The increased emphasis on PRA has spurred multiple efforts at the national and international level to design frameworks for the conduct of these analyses. As approaches to pest risk analysis proliferate, and the importance of the analyses grows, concerns have arisen about the scientific and technical conduct of pest risk analysis. In January of 1997, the Harvard Center for Risk Analysis (HCRA) held an invitation-only workshop in Washington, D.C. to bring experts in risk analysis and pest characterization together to develop general principles for pest risk analysis. Workshop participants examined current frameworks for PRA, discussed strengths and weaknesses of the approaches, and formulated principles, based on years of experience with risk analysis in other setting and knowledge of the issues specific to analysis of pests. The principles developed highlight the both the similarities of pest risk analysis to other forms of risk analysis, and its unique attributes.     

Penalties and payoffs: The short-term economic consequences of human capital acquisition for resettled refugees in the United States

The relationship between refugee investments in human capital and short-run economic outcomes may influence the extent to which refugees invest in human capital that is associated with positive future economic mobility. Using data from the Annual Survey of Refugees from 2016 and 2017 we assess the relationship between recent investments in human capital and hourly wages for employed refugees in the United States. Results suggest that recent job training has a positive effect on hourly wages. In contrast, enrollment in English classes and educational programmes have no short-term positive effects on hourly wages. When combined with the pressure resettled refugees experience to find employment quickly, these results suggest that the lack of short-term wage benefits from English language or educational courses may dissuade refugees from sufficiently investing in the amount of English language or education necessary to promote positive long-term economic mobility.     

Maternal depression,parental attributions,and adolescent psychopathology: An evaluation using observational and video-mediated recall methods

Parenting styles associated with maternal depression are a risk factor for adolescent psychopathology, and maternal attributional styles may be a key mechanism in this relationship. Mother-adolescent dyads (N = 180; 96 male; ages 10–15) completed in-person interactions and then the mothers participated in a video-mediated recall procedure to assess maternal attributions. Maternal depression was associated with negative attributions. Negative attributions were associated with low parental acceptance, aggressive parenting, and low positive parenting. Positive maternal attributions were associated with less aggressive parenting, and more positive parenting during one interaction task. Adolescent externalizing behaviors were associated with negative attributions. Future research should evaluate whether maternal attributions mediate the association between maternal depression and both parenting behaviors and adolescent mental health.     

A test statistic for weighted runs

A new test statistic based on runs of weighted deviations is introduced. Its use for observations sampled from independent normal distributions is worked out in detail. It supplements the classic χ² test which ignores the ordering of observations and provides additional sensitivity to local deviations from expectations. The exact distribution of the statistic in the non-parametric case is derived and an algorithm to compute p-values is presented. The computational complexity of the algorithm is derived employing a novel identity for integer partitions.     

Attitude–behavior consistency in household water consumption

The purpose of this paper is to examine how environmental attitudes and concern about water scarcity translate into water conservation behavior. The study considers whether Oregonians environmental concern measured by the New Environmental Paradigm scale and sociodemographic characteristics influence personal water conservation activities. Using a survey conducted in the spring of 2010 of Oregon residents, the interaction of environmental concern and sociodemographics that predict identified water conservation behaviors are considered.
