Amenities and the labor earnings function

Desirable locations are, other things equal, expected to be characterized by a mix of higher rents or lower wages. That is, if one area is more attractive than others, inmigration would occur, driving up the demand for land (hence raising rents) and increasing the supply of labor (hence lowering wages). The in-movement will continue until utility is the same across locations in equilibrium. Failing to hold constant amenities in the traditional earnings functions employed by labor economists will result, then, in omitted-variable bias if worker characteristics (years of schooling, union membership, and so on) are correlated with amenities. By way of illustration, our empirical analysis suggests that as much as 50 percent of the apparent return to unionization may be due to the impact of undesirable amenities, resulting in compensating higher wages, in areas of union strength — unionization is being credited with wage gains that properly should be attributed to climate and other (dis)amenities. Similar, though smaller, effects on other coefficients of the earnings function variables are presented.     

Wildfire Exposure Analysis on the National Forests in the Pacific Northwest,USA

We analyzed wildfire exposure for key social and ecological features on the national forests in Oregon and Washington. The forests contain numerous urban interfaces, old growth forests, recreational sites, and habitat for rare and endangered species. Many of these resources are threatened by wildfire, especially in the east Cascade Mountains fire‐prone forests. The study illustrates the application of wildfire simulation for risk assessment where the major threat is from large and rare naturally ignited fires, versus many previous studies that have focused on risk driven by frequent and small fires from anthropogenic ignitions. Wildfire simulation modeling was used to characterize potential wildfire behavior in terms of annual burn probability and flame length. Spatial data on selected social and ecological features were obtained from Forest Service GIS databases and elsewhere. The potential wildfire behavior was then summarized for each spatial location of each resource. The analysis suggested strong spatial variation in both burn probability and conditional flame length for many of the features examined, including biodiversity, urban interfaces, and infrastructure. We propose that the spatial patterns in modeled wildfire behavior could be used to improve existing prioritization of fuel management and wildfire preparedness activities within the Pacific Northwest region.     

Replacing the Elderly With Older Adults in JGSW Publications

Summary

This article focuses on the important contributions the venerable Harriet Tubman made to the field of housing for older persons and other populations at risk. It uses an historical approach to document the importance of early housing and self-help initiatives in the African American community. It embraces Harriet Tubman and other early housers for their good works and acknowledges them as contributors to the rich legacy of community social work practice and its sage principles of empowerment and self-help. The article presents a nexus between the current housing status of older Blacks and the double jeopardy status imposed by historical discrimination.     

Early Adult Obesity and U.S. Women's Lifetime Childbearing Experiences

Literature from multiple disciplines suggests that women who are obese during early adulthood may accumulate social and physiological impediments to childbearing across their reproductive lives. This led the authors to investigate whether obese young women have different lifetime childbearing experiences than leaner peers by analyzing data from 1,658 female participants in the 1979 National Longitudinal Survey of Youth. Study sample members were nulliparous women ages 20–25 in 1982. The authors examined their childbearing experiences between 1982 and 2006 and found that young women who were obese at baseline had higher odds of remaining childless and increased odds of underachieving fertility intentions than young women who were normal weight at baseline. These results suggest that obesity has long‐term ramifications for women's childbearing experiences with respect to whether and how many children women have in general and relative to the number of children they want.     

Exercise Motivation of College Students in Online,Face-to-Face,and Blended Basic Studies Physical Activity and Wellness Course Delivery Formats

Abstract

Objective: The purpose of this study was to assess exercise motivation among college students self-selected into 4 online (OL) and face-to-face (F2F) basic studies’ physical activity and wellness course delivery formats. Participants/Methods: Out of 1,037 enrolled students during the Spring 2009 semester, 602 responded online to demographic questions and to the Behavioural Regulation in Exercise Questionnaire, which assessed exercise motivation on 5 subscales. Results: There were no significant differences (p > .05) in exercise motivation for students across course delivery formats, but there was a significant difference in age and employment status between the completely OL and F2F course formats. Conclusions: Health and physical educators can utilize these findings to better understand that physical activity and wellness students are not necessarily trying to avoid physical activity when selecting the OL course format, but are more likely trying to balance work and school responsibilities and need greater flexibility in time and location.     

Does it or Doesn't it? Geographic Differences and the Costs of Living

Abstract The relative cost of living in rural areas has long been of interest to rural sociologists. Today, the popular perception is that rural prices are lower. This study examines geographic differences in the costs of living in Kentucky. The results indicate that, contrary to the popular perception, when prices of the same products and services were compared, there was no consistent pattern of lower prices in the rural counties. Furthermore, differences in the material conditions of rural living meant that there were additional costs that price comparisons alone did not capture.     

Poisson-Driven Stationary Markov Models

ABSTRACT

We propose a simple yet powerful method to construct strictly stationary Markovian models with given but arbitrary invariant distributions. The idea is based on a Poisson-type transform modulating the dependence structure in the model. An appealing feature of our approach is the possibility to control the underlying transition probabilities and, therefore, incorporate them within standard estimation methods. Given the resulting representation of the transition density, a Gibbs sampler algorithm based on the slice method is proposed and implemented. In the discrete-time case, special attention is placed to the class of generalized inverse Gaussian distributions. In the continuous case, we first provide a brief treatment of the class of gamma distributions, and then extend it to cover other invariant distributions, such as the generalized extreme value class. The proposed approach and estimation algorithm are illustrated with real financial datasets. Supplementary materials for this article are available online.
