Checkbooks in the Heartland: Change over Time in Voluntary Association Membership

Numerous scholars documented declines in America's social capital through the mid‐1990s but we do not know whether the trend has continued. Further, despite warnings by Robert Putnam and Theda Skocpol that the quality of Americans' voluntary association memberships has also deteriorated—moving from active, “face‐to‐face” memberships to passive, “checkbook” memberships—data have not been available to test this claim. In this article, we use both the Iowa Community Survey and the General Social Survey to explore the changing nature of voluntary association membership between 1994 and 2004. We demonstrate that not only are declines in voluntary association memberships continuing in the new century but there has been a shift in the intensity of voluntary association participation over time. We observe a decline in active membership over time and an increase in checkbook membership over time. These findings provide support for Putnam's claim that checkbook membership is increasing at the expense of more active types of memberships.     

Radon Testing Behavior in a Sample of Individuals with High Home Radon Screening Measurements

Although radon exposure has been identified as the second leading cause of lung cancer, fewer than 6% of U.S. homeowners test their homes for radon. This report examines participants'follow-up radon testing behavior subsequent to receiving an initial screening radon level greater than 20 pCi/L. Sixty-two participants in the Iowa State-Wide Rural Radon Screening Survey who had radon screening measurements over 20 pCi/L were questioned by phone survey 3 months after receipt of their radon screening result to assess: whether participants were aware of radon's health risk; if participants recalled the radon screening results; how participants perceived the relative health risk of radon and whether participants planned follow-up radon testing. Only 19% of the respondents specifically identified lung cancer as the possible adverse health outcome of high radon exposure, and the majority of participants underestimated the health risks high radon levels pose when compared to cigarettes and x-rays. In addition, less than one third (29%)of the participants actually remembered their radon screening level within 10 pCi/L 3 months after receiving their screening results. Only 53% of the individuals correctly interpreted their screening radon level as being in the high range, and only 39% of the participants planned follow-up radon measurements. Receipt of radon screening test results indicating high radon levels was not an adequate motivational factor in itself to stimulate further radon assessment or mitigation. Our findings suggest that free radon screening will not result in a dramatic increase in subsequent homeowner initiated remediation or further recommended radon testing.     

How changes in price and salary affect economic satisfaction: Information integration models and inference processes

Preliminary studies demonstrated the interactive effects of changes in salary and inflation rate on feelings of personal satisfaction, and showed that the effects of price increases in different cost categories could he described by a weighted average model. Participants in the main study were presented with varying hypothetical economic situations which included salary changes (raises) as well as specific price changes. A ratio model was found to describe how raise levels and price increases were combined. The rationality of this model was discussed in terms of how variations in price and income would affect the amount of a given commodity that could he purchased. On some trials only partial information was presented. Low ratings of personal satisfaction were produced when information about raises was missing, and high ratings were produced when information about price increases was missing. These results were discussed in terms of inferences people make when a key source of information is missing.     

Incorporation vs. Separation:

This article examines the approach to the study of women and politics in the People's Republic of China and assesses the impact of gender studies (or lack of it) on women and the larger part of society in China. The author argues that most materials for studying women and politics in China emanate from the office of the All-China Women's Federation, an appendage of the Chinese Communist Party, and not from political science textbooks. This approach, however, falls short of addressing major political and economic problems facing women of China.     

Frequent Card Playing and Pathological Gambling: The Utility of the Georgia Gambling Task and Iowa Gambling Task for Predicting Pathology

The current investigation examined performance on two laboratory-based gambling tasks, the Georgia Gambling Task (GGT; Goodie, 2003. The effects of control on betting: Paradoxical betting on items of high confidence with low value. Journal of Experimental Psychology: Learning, Memory, and Cognition, 29, 598–610) and the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994. Insensitivity to future consequences following damage to human prefrontal cortex. Cognition, 50, 7–15), as well as self-reported markers of gambling pathology using the Diagnostic Interview for Gambling Severity (DIGS; Winters, Specker, & Stinchfield, 2002. The downside: Problem and pathological gambling (pp. 143–148). Reno, NV: University of Nevada, Reno) among a sample of undergraduate students who are frequent card players. Two hundred twenty-one participants (55 female and 166 male; mean age 19.21 years) who self-classified as playing cards at least once per month completed these measures. Performance on GGT and IGT systematically related to gambling-related pathology in several ways. Overconfidence and bet acceptance on the GGT, and myopic focus on reward on the IGT, predicted gambling related pathology. GGT and IGT performance correlated with each other, but both contributed independently to predicting gambling pathology. Card playing frequency predicted gambling pathology but not GGT or IGT performance. Discussion focuses on the role of biases of judgment and risky decision making in pathological gambling.     

Examining DSM-IV Criteria for Pathological Gambling: Psychometric Properties and Evidence from Cognitive Biases

We examined the DSM-IV criteria for pathological gambling as assessed with the DSM-IV-based Diagnostic Interview for Gambling Severity (DIGS; Winters, Specker, & Stinchfield, 2002). We first analyzed the psychometric properties of the DIGS, and then assessed the extent to which performance on two judgment and decision-making tasks, the Georgia Gambling Task (Goodie, 2003) and the Iowa Gambling Task (Bechara, Damasio, Damasio, & Anderson, 1994), related to higher reports of gambling pathology. In a sample of frequent gamblers, we found strong psychometric support for the DSM-IV conception of pathological gambling as measured by the DIGS, predictive relationships between DIGS scores and all cognitive performance measures, and significant differences in performance measures between individuals with and without pathological gambling. Analyses using suggested revisions to the pathological gambling threshold (Stinchfield, 2003) revealed that individuals meeting four of the DSM-IV criteria aligned significantly more with pathological gamblers than with non-pathological gamblers, supporting the suggested change in the cutoff score from five to four symptoms. Discussion focuses on the validity of the DSM-IV criteria as assessed by the DIGS and the role of cognitive biases in pathological gambling.     

Retrospective Temporal and Spatial Mobility of Adult Iowa Women

Human exposure assessments require a linkage between toxicant concentrations in occupied spaces and the receptor's mobility pattern. Databases reporting distinct populations' mobility in various parts of the home, time outside the home, and time in another building are scarce. Temporal longitudinal trends in these mobility patterns for specific age and gender groups are nonexistent. This paper describes subgroup trends in the spatial and temporal mobility patterns within the home, outside the home, and in another building for 619 Iowa females that occupied the same home for at least 20 years. The study found that the mean time spent at home for the participants ranged from a low of 69.4% for the 50-59 year age group to a high of 81.6% for the over 80-year-old age group. Participants who lived in either one- or two- story homes with basements spent the majority of their residential occupancy on the first story. Trends across age varied for other subgroups by number of children, education, and urbadrural status. Since all of these trends were nonlinear, they indicate that error exists when assuming a constant, such as a 75% home occupancy factor, which has been advocated by some researchers and agencies. In addition, while aggregate data, such as presented in this report, are more helpll in deriving risk estimates for population subgroups, they cannot supplant good individual-level data for determining risks.     

Experimental evaluation of a humanities program

This research sought to determine the effects of a one-hour humanities lecture concerning midwest architectural preservation on a group of college undergraduates. Effects were assessed by a semantic differential procedure which revealed two factors in a pre-treatment trial. A four-group design required administration of the instrument to two groups one week prior to the lecture, and to all groups one week following the lecture. ANOVA and post hoc analyses revealed significant changes in the experimental group's “semantic space” on three of eight architectural concepts which were assessed. The results provide an empirical basis for the success of the program which the humanities people had “known” all along.
