Estimating Willingness to Pay for River Amenities and Safety Measures Associated with Shale Gas Extraction

This paper utilizes a Contingent Valuation Method survey of a random sample of residents to estimate that households are willing to pay an average of $12.00 per month for public projects designed to improve river access and $10.46 per month for additional safety measures that would eliminate risks to local watersheds from drilling for natural gas from underground shale formations. These estimates can be compared to the costs of providing each of these two amenities to help foster the formation of efficient policy decisions.

Evaluation of Current Repair Criteria for Longitudinal Barrier with Crash Damage

To protect motorists and avoid tort liability, highway agencies expend considerable resources to repair damaged longitudinal barriers, such as w-beam guardrails. With limited funding available, though, highway agencies are unable to maintain all field-installed systems in the ideal as-built condition. Instead, these agencies focus on repairing only damage that has a detrimental effect on the safety performance of the barrier. The distinction between minor damage and more severe performance-altering damage, however, is not always clear. This paper presents a critical review of current United States (US) and Canadian criteria on whether to repair damaged longitudinal barrier. Barrier repair policies were obtained via comprehensive literature review and a survey of US and Canadian transportation agencies. In an analysis of the maintenance procedures of 40 US States and 8 Canadian transportation agencies, fewer than one-third of highway agencies were found to have quantitative measures to determine when barrier repair is warranted. In addition, no engineering basis for the current US barrier repair guidelines could be found. These findings underscore the importance of the development of quantitative barrier repair guidelines based on a strong technical foundation.

Do College Women Facilitate the Sexual Assault of Their Same-Gender Peers?

National studies indicate that approximately 25 percent of women have been sexually assaulted by the time they finish college. Although male peers are often the perpetrators, women also engage in behaviors with their female peers that may increase the risk of sexualassault. In the present study, we sought to determine how often college women engaged in these behaviors (i.e. “female facilitation”). Participants were 373 female students (sophomorethrough senior; Greek and independent) who completed an online survey containing measures of sexual assault, alcohol consumption, and female facilitation. The female facilitation measure indexed both “facilitator” behaviors (those directed toward others thatlikely increase the risk of sexual assault victimization) and “facilitatee” behaviors (those that may increase risk of sexual assault victimization), and the two sets of items werecounterbalanced across participants. Descriptive statistics showed an overall prevalence rate for any type of sexual assault was 44.2%. Scores on the facilitator and facilitatee versions ofthe female facilitation measure were highly correlated. Facilitation was highly correlated with alcohol consumption, and being a faciltatee was moderately correlated with sexual assault. Results were consistent with some of our expectations regarding the relationships among facilitation, alcohol consumption, sexual assault, and demographic variables. Limitations of the methods and the implications of the findings for understanding campussexual assault will be discussed.

The Impact of Parental Psychological Control on College Students’ Relational Aggression and Friendship Quality

The present study investigated the relationships between parental psychological control and college students’ relational aggression and friendship quality. Based on previous research, it was expected that parents’ use of psychological control would be associated with students’ increased use of relational aggression with peers and lower friendship quality. Students completed a series of survey measures assessing their mothers’ and fathers’ use of psychological control, behavioral control, and warmth/acceptance. Students also completed a series of survey measures assessing their friendship quality, social skills, relational aggression, self-esteem, and social desirability. The study’s findings revealed that parental psychological control was associated with and predicted students’ increased use of relational aggression with peers. Parental psychological control was also associated with students’ lower friendship quality. However, parents’ use of psychological control did not predict students’ friendship quality after accounting for the influence of students’ personal and peer relationship variables. This finding suggests that characteristics of peer relationships may play a larger role than parenting behaviors in shaping college students’ friendships. The study also found that students who displayed higher levels of relational aggression had lower quality friendships. Other findings revealed that the relationship between parental psychological control and students’ friendship quality can be partially explained by students’ use of relational aggression with peers. Students’ friendship quality can also help to explain the influence of parental psychological control on students’ relational aggression. In addition, the study found that combinations of parenting behaviors were more informative predictors of students’ relational aggression and friendship quality than psychological control alone. Finally, this study revealed the importance of assessing participants’ social desirability when measuring sensitive personal qualities such as relational aggression, friendship quality, and self-esteem. Overall, this study contributes to the field of research on parental psychological control by revealing its effects on college students’ relational aggression and friendship quality.
