Age, Health and the Willingness to Pay for Mortality Risk Reductions: A Contingent Valuation Survey of Ontario Residents

We present the results of a contingent valuation survey eliciting willingness to pay (WTP) for mortality risk reductions. The survey was self-administered using a computer by 930 persons in Hamilton Ontario aged 40 to 75. Visual and audio aides were used to enhance risk comprehension. Mean WTP figures for a contemporaneous risk reduction imply a value of a statistical life of approximately C$l.2 to C$3.8 million (1999 C$). Mean WTP is constant with age up to 70 years, and is about 30 percent lower for persons aged 70 and older. WTP is unaffected by physical health status, but is affected by mental health.     

Opposition to the Legitimacy of Hate Crime Laws: The Role of Argument Acceptance, Knowledge, Individual Differences, and Peer Influence

Hate crime laws are a highly controversial legal approach in society's response to intergroup violence. Argument acceptance, knowledge, and individual differences were examined in relationship to attitudes about these laws. These variables were also considered in terms of efforts to influence a peer's beliefs about hate crime laws. One-hundred and sixty-seven participants completed a measure of knowledge of human rights laws, Gough's Pr scale, the Selznick and Steinberg anti-Semitism scale, and Cuellar's Machismo scale. Hate crime attitudes were measured on an affect rating scale and six statements reflecting arguments favoring and opposing hate crime laws. Peer influence was examined on Interpersonal Power Inventory (IPI). Results showed that while most participants endorsed positive attitudes about hate crime laws, men—and both women and men who endorsed machismo attitudes—were more likely to agree with media distortion and identity politics arguments opposing hate crime laws. The Pr and machismo scales predicted greater effort on the IPI to influence peer attitudes about hate crime laws, after controlling for demographic differences of the participants. These findings indicate that more explicitly biased individuals were more effortful in trying to change the attitudes of peers concerning the legitimacy of hate crime laws.     

Assessing Racial and Ethnic Differences in Attitudes towards the Use of Physical Discipline in Parenting: A Mixed-Methods Approach

Using a concurrent nested mixed-methods approach, this study assessed racial and ethnic differences in attitudes towards the use of physical discipline in parenting based on data recently collected in Nebraska. Relative to Non-Hispanic White parents, African American parents were more likely to approve the practice of physical punishment to correct misbehavior of children, whereas Hispanic parents were less likely to support physical punishment. There was a positive relationship between acculturation and approval of physical discipline among Hispanic parents. Understanding these differences can help inform the design and implementation of future parenting education programs for parents of different racial and ethnic backgrounds.     

Assessing the Needs of Older Gay,Lesbian, Bisexual,and Transgender People: A Service-Learning and Agency Partnership Approach

A county agency and a social work research class partnered to conduct a state-mandated needs assessment of older gay, lesbian, bisexual, and transgendered people (GLBT). A survey design with purposive sampling of GLBT people over 60 yielded 38 participants. Findings included that the Internet was a viable means to reach this population and student awareness increased. Areas of greatest unmet need were GLBT-oriented/friendly legal advice, social events, grief and loss counseling, social workers, and assisted living. Some participants perceived existing senior services as unfriendly or hostile to GLBT persons. Recommendations include continued use of service-learning research and expanded needs assessment efforts.

A Contextual Approach to the Development of Self-regulatory Competencies: The Role of Maternal Unresponsivity and Toddlers' Negative Affect in Stressful Situations

A prospective study examined the effects of maternal unresponsivity and of toddlers’ own negative affect on the child's subsequent ability to use effective attentional control strategies in preschool. Maternal and child behaviors were measured in situations that varied in the level of stress to test the hypothesis that behaviors in high stress situations would be more diagnostic of children's subsequent self‐regulatory behavior. As predicted, both maternal unresponsivity and toddlers’ negative affect, particularly in a high stress as opposed to a low stress situation, predicted children's later use of ineffective attentional control strategies. Similarly, maternal disengagement that occurred contingent to toddlers’ distress predicted ineffective attentional control strategies whereas maternal disengagement in response to toddlers’ non‐distress behaviors did not. The findings supported the utility of a contextual approach to understanding the impact of maternal and child characteristics on the development of self‐regulatory skills.
