Does it Work for Them — Does it Work for Us? Evaluating a New Model of Team Practice

This article describes a change in team practice from a model targeted at individual families to a combined model that supplements family therapy with group programs for children. Unacceptably long waiting lists for family counselling services, high levels of stress in clinicians, and consumer dissatisfaction motivated this change. Robust quantitative data and a qualitative analysis of the project confirm that the change has made a positive impact and the new treatment model deserves to be continued. The article concludes that internal team changes are insufficient in a treatment context which requires more profound changes beyond the boundaries of the team.     

Modeling Age Differences in Infant Category Learning

We used an encoder version of cascade correlation to simulate Younger and Cohen's (1983, 1986) finding that 10‐month‐olds recover attention on the basis of correlations among stimulus features, but 4‐ and 7‐month‐olds recover attention on the basis of stimulus features. We captured these effects by varying the score threshold parameter in cascade correlation, which controls how deeply training patterns are learned. When networks learned deeply, they showed more error to uncorrelated than to correlated test patterns, indicating that they abstracted correlations during familiarization. When prevented from learning deeply, networks decreased error during familiarization and showed as much error to correlated as to uncorrelated tests but less than to test items with novel features, indicating that they learned features but not correlations among features. Our explanation is that older infants learn more from the same exposure than do younger infants. Unlike previous explanations that postulate unspecified qualitative shifts in processing with age, our explanation focuses on quantitatively deeper learning with increasing age. Finally, we provide some new empirical evidence to support this explanation.     

American Roulette: The Effect of Reminders of Death on Support for George W. Bush in the 2004 Presidential Election

An experiment was conducted to assess the effect of a subtle reminder of death on voting intentions for the 2004 U.S. presidential election. On the basis of terror management theory and previous research, we hypothesized that a mortality salience induction would increase support for President George W. Bush and decrease support for Senator John Kerry. In late September 2004, following a mortality salience or control induction, registered voters were asked which candidate they intended to vote for. In accord with predictions, Senator John Kerry received substantially more votes than George Bush in the control condition, but Bush was favored over Kerry following a reminder of death, suggesting that President Bush's re-election may have been facilitated by nonconscious concerns about mortality in the aftermath of September 11, 2001.     

The inclusion of minority groups in clinical trials: problems of under representation and under reporting of data

Objective: To evaluate the representation of minority groups in randomized control trials (RCTs), and the frequency with which this information is reported. Study Design: Reviewers collected data on the racial/ethnic composition of study samples from all RCTs published in six leading medical journals in 1999. Results: Of the 280 RCTs, most (204, 71.3%) provided no information on the race/ethnicity of participants. Of the 89 U.S.-based RCTs, 50 (56.1%) reported their minority distribution. Relative to other trials, those funded by the National Institute of Health (NIH) (n = 52) were more likely to report race/ethnicity data (55.8% vs. 23.7%; x2 = 20.9, p <_0.001) and to include nonwhite participants (13.5 % vs. 12.5%; x2=22.7, p<_0.001). Conclusion: Minority groups are currently under-represented in clinical trials. Information on the race and ethnicity of clinical trial participants is currently underreported in six leading medical journals. Reporting of minority group information was significantly better only in NIH funded trials, which also were more likely to include nonwhite participants. This suggests that mandatory reporting policies may have a positive effect on both reporting and representation.     

The ethics of human reproductive cloning: when world views collide

Two camps in bioethics with seemingly opposing world views have staked out conflicting positions regarding the ethics of human reproductive cloning. These camps do not appear to share common concepts or ways of reasoning through which to exchange views and come to a meeting of minds about uses of this technology. Yet analysis of their respective approaches to several issues surrounding reproductive cloning, such as where the ethical limits of individual reproductive choice lie, whether the use of this technology would violate human dignity, whether it would create risks to the resulting fetuses and children that would make its use intolerable, and whether it would challenge certain core social values, reveals that they are not wholly opposed to one another. Indeed, it displays that they hold certain beliefs, values, and concerns in common. Moreover, it indicates that the different world views that they each presuppose, while flawed in certain respects, do not collide in every respect, but can be reconciled in significant ways that provide fertile ground for agreement about several issues related to human reproductive cloning.
