The U.S. EPA Geographic Information System for Mapping Environmental Releases of Toxic Chemical Release Inventory (TRI) Chemicals

This study characterizes the environmental releases of toxic chemicals of the Toxic Chemical Release Inventory (TRI) in the southeastern United States by using the U.S. Environmental Protection Agency (EPA) Geographic Information System (GIS) to map them. These maps show that the largest quantities of TRI releases in the Southeast are usually near densely populated areas. This GIS mapping approach takes the first steps in defining those areas in the region which may be potential exposure zones and which could be strategic targets for future risk screening efforts in this geographic area.     

Teaching accountability: using client feedback to train effective family therapists

The AAMFT Task Force on Core Competencies (Nelson et al., 2007) proposed that marriage and family therapy (MFT) educators teach and provide evidence of trainee competence beyond coursework and accrued clinical hours. This article describes the integration of a systematic client feedback protocol into an MFT-accredited program's curricula to address the call for outcome-based learning. Outcome management (OM) provides a framework for teaching and assessing trainee effectiveness. Continuous incorporation of client feedback embodies collaborative, strengths-based, integrative, and diversity-centered program values. Students learn a system for being accountable to clients, the profession, and service communities.     

Gay men and lesbians' experiences in and expectations for interactions with heterosexuals

We analyzed 97 gay men's and lesbians' experiences with and expectations for interactions with majority group members. Respondents described reactions to previous or imagined future interactions with an unfamiliar heterosexual person who had just become aware that the respondent was lesbian or gay. Results indicated that respondents are more proactive than reactive (in contrast to expectation states theories), that the contact hypothesis can be appropriately applied to this group, even though the formulation of the theory was based upon negative attitudes in the absence of extensive contact, and that they have different reactions for people of different prejudice levels, rather than being globally suspicious, as is predicted by many intergroup theories. Future research should direct more attention to the stigmatized group members' attitudes about and reactions toward the majority group.     

Comparative Use of Complementary Medicine,Allied Health,and Manual Therapies by Middle-Aged and Older Australian Women

We compared use of Complementary and Alternative Medicines (CAM) and therapies, Allied Health interventions (AH), and Manual Therapies (MT) in middle-aged and older Australian women. Cross-sectional data from the 2007 phase of the Longitudinal study of Aging in Women (LAW study) was analyzed. Self-reported 12-month usage patterns of CAM, AH, and MT were determined by mailed questionnaire. Results revealed that 56.2% of the middle-aged group, and 55.0% of the older group used CAM, AH, and MT services in the previous 12 months (a nonsignificant difference). In contrast, there was a highly significant difference between the overall use of CAM products by middle-aged women (88.2%) and older women (67.7%: p = .002).     

An example arising from berkson's conjecture

Berkson (1980) conjectured that minimum x² was a superior procedure to that of maximum likelihood, especially with regard to mean squared error. To explore his conjecture, we analyze his (1955) bioassay problem related to logistic regression. We consider not only the criterion of mean squared error for the comparison of these estimators, but also include alternative criteria such as concentration functions and Pitman's measure of closeness. The choice of these latter criteria is motivated by Rao's (1981) considerations of the shortcomings of mean squared error. We also include several Rao-Blackwellized versions of the minimum logit x² the purpose of these comparisons.     

A Bayes Theorem Urn Model Optimization Problem

An urn model is a finite collection of indistinguishable urns together with an arbitrary distribution of a finite number of balls (bills) of k colors (denominations) into the urns. A Bayes theorem expectation optimization problem associated with certain urn models is discussed.
