Social Capital and Economic Performance in the American States*

Objective. This study tests the claim that areas with higher levels of social capital have superior economic performance. Method. The 14‐measure index of social capital created by Robert Putnam is reconstructed for an extended time period and integrated into cross‐sectional regression models including physical capital, human capital, and other factors relevant to state economic performance. Results. The analysis shows that social capital has no discernable influence on aggregate measures of output and employment. However, it does have a positive and significant impact on measures of economic equality and employment stability. Conclusions. This study does not support the claim that social capital is a general prerequisite for prosperity, but it does suggest that it may serve to reinforce a particular mode of communitarian economic development.     

Some Bayesian Methods for Two Auditing Problems

Two problems of interest to auditors are: (i) finding an upper bound for the total amount of overstatement of assets in a set of accounts; and (ii) estimating the amount of sales tax owed on a collection of transactions. For the first problem, the Stringer bound has often been used despite the fact that in many cases it is known to be much too large. Here we will introduce a family of stepwise Bayes models that yields bounds that are closely related to the Stringer bound but are less conservative. Then we will show how this approach can also be used for solving the second problem. This will allow practitioners with modest amounts of prior information to select inference procedures with good frequentist properties.     

Awareness and use of a university recreational trail

The purpose of this study was to assess awareness and use of a university recreational trail. The authors used an Internet questionnaire developed by the university's Institutional Research Department, with questions derived from the Environmental Supports for Physical Activity Questionnaire and the National College Health Risk Behavior Survey Physical Activity Module. Four hundred and sixty-seven undergraduate college students participated. Ninety-one percent of students reported being aware of the trail, and 73% reported using the trail. Sixty-four percent of students reported seeing signage referring to the recreational trail. Sixty-seven percent of the students reported using the trail once in the past week, 7% reported using the trail twice in the past week, and only 2% of the students reported using the trail more than 3 times in the past week. Sixty-two percent reported using the trail with another individual. Students who were aware of the trail were more likely to use the trail. However, of the individuals who used the trail, the majority only used the trail 1 day a week. University programming is needed to increase trail usage among college students.     

Formative evaluation of a motivational intervention for increasing physical activity in underserved youth

The present study was designed to develop an innovative motivational intervention (based on Self-Determination Theory and Social Cognitive Theory) to increase physical activity (PA) in underserved adolescents. Sixty-four adolescents (35 females, 29 males; 50% minority; 65% on reduced lunch program; ages 11-13 yr) participated in either an 8-week motivational intervention after-school (n = 32) or a typical after-school program (n = 32). The conceptual framework for the intervention targeted the social environment (perceived autonomy, perceived social support, participation, fun), cognitive mediators (perceived choice, self-efficacy, and relatedness/belongingness), and motivational orientation (intrinsic motivation, commitment, positive self-concept). Formative evaluation data was collected by staff through daily forms throughout the 8-week program and through observational data completed by independent objective observers during 2 weeks of the program. The major themes that were identified addressed theoretical concepts regarding the intervention and logistical issues in delivering the intervention. The data revealed information regarding the importance of the cognitive appropriateness of the PA and motivational activities, the environmental climate for promoting nurturing relationships, developing specific strategies for increasing intrinsic rather than extrinsic reinforcement, and developing methods for preventing social "cliques" and gender conflicts to maintain an appropriate level of support in the social climate. Themes for training staff included focusing on team building, leadership, and nurturing. This formative evaluation is being used to formalize a randomized trial to test the effects of a student-centered motivational intervention on increasing PA in underserved 6th graders.     

Welfare reform: challenges for grandparents raising grandchildren

This paper examines the impact of Temporary Aid to Needy Families (TANF) on a growing constituency that may require welfare assistance: grandparents raising grandchildren. A brief review of the demographics of grandparent caregivers is followed by an exploration of welfare reform legislation, including work requirements and the Healthy Marriage Initiative (HMI). The importance of state-level policies in assisting grandparent-headed households, particularly health care, school enrollment, and housing policies, are also discussed. The paper concludes by offering implications for welfare policies in terms of their impact on intergenerational households headed by grandparents.
