In a recent article in this journal, Berument, Dogan, and Onar (2010) challenged the existence of the previously documented daylight-saving effect. Kamstra, Kramer, and Levi's original finding (2000) was that average stock market returns on Mondays following time changes arc economically and statistically significantly lower than typical Monday returns, Kamstra, el al. hypothesized that the effect may arise due to heightened anxiety or risk aversion on the part of market participants after they experience a 1-hr. disruption in their sleep habits, in accordance with prior findings in the psychology literature linking sleep desyn- chronosis with anxiety. Berument, et al. replicated the original findings using ordinary least squares estimation, but when they modeled the mean of returns using a method prone to producing biased estimates, they obtained puzzling results. The analysis here, based on standard, unbiased modeling techniques, shows that the daylight-saving effect remains intact in the U.S. [ABSTRACT FROM AUTHOR]

It is becoming increasingly difficult for a single profession to respond adequately to clients who have multiple needs. Managed care and other changes in the provision of human services demand close interaction among professionals to facilitate services to clients and to avoid duplication of effort. While professional schools shape the thinking and practice of students to meet client needs, few models exist for training them to work collaboratively with members of other professions. This paper presents an evaluation of a training model that introduces graduate students from the professions of clinical psychology, education, physical therapy, and social work to interdisciplinary practice. Results indicate that, when compared with a control group, students who participated in the training model exhibited significant differences in learning on both knowledge and practice dimensions of interdisciplinary practice.

Survey data obtained from 119 women who were prostituting in escort agencies and on the street in Phoenix, Arizona provide insight into women's emotional experiences of turning tricks. Results indicate that women experience a range of negative emotions while performing sex acts with customers including feelings of sadness, worthlessness, anger, anxiety, and shame. Far less frequently, emotional experiences of turning tricks were described as involving feelings of excitement and desirability. In addition to experiencing acts of prostitution as overwhelmingly emotionally unpleasant, if not traumatic, women feel more negatively about themselves after entering prostitution and would strongly prefer to leave prostitution for a different occupation with similar earnings. Findings from this study suggest that while some women may enter prostitution to support a drug or alcohol habit, they also use these substances once in prostitution to detach emotionally and to cope with fears of being hurt in prostitution. Practical implications of these findings for therapists, social workers, and substance abuse counselors are discussed. [ABSTRACT FROM PUBLISHER]

The signaling impact of a human beta1-adrenergic receptor (beta1 AR) polymorphism at residue 49 of the aminoterminus (Ser-to-Gly substitution) was studied by recombinantly expressing each receptor. The two receptors displayed identical agonist and antagonist binding affinities. Furthermore, basal and agonist-stimulated adenylyl cyclase activities were the same for these receptors as assessed in both cell types. Although short-term agonist exposure resulted in similar degrees of receptor internalization, long-term agonist-promoted downregulation was greater for Gly49 compared with Ser49. The Gly49 receptor underwent a 24 +/- 3% loss of receptor density after exposure to isoproterenol for 18 h, whereas Ser49 underwent no such loss. In studies in which receptor synthesis was inhibited, agonist-promoted downregulation for Gly49 was 55 +/- 3% compared with 36 +/- 5% for Ser49. In the absence of agonist, degradative turnover of each receptor was the same. Immunoblotting revealed that some of the Ser49 receptor exists as a highly N-glycosylated form (approximately 105-kD molecular mass), which is not present with Gly49. Thus the phenotype of the Gly49 polymorphic receptor is that of wild-type coupling with enhanced agonist-promoted downregulation, which is associated with altered N-glycosylation. Based on this cellular phenotype, the beta1 AR Gly49 polymorphism may impart a beneficial effect in chronic heart failure.
