Pubertal Timing and Adolescent Alcohol Use: The Mediating Role of Parental and Peer Influences

Using intergenerational, prospective data at ages 9 months, 7, 11, and 14 years from the nationally representative United Kingdom Millennium Cohort Study, this interdisciplinary study unpacks why 14-year-old adolescents with early perceived pubertal timing (PT) were more likely to drink alcohol (ever, frequent, and binge drinking) compared to those whose PT was on-time or late (5,757 girls, 5,799 boys; 80% White, 10% Asian, 3% Black, and 7% Other British). Parents allowed drinking among 22% (18%) of early PT girls (boys) compared to 11% of late PT adolescents; formal mediation models showed differences by PT in parent permissiveness and gains in alcohol-using friends primarily explained age 14 PT-drinking associations. Parental alcohol permissiveness should be a key prevention target for early PT adolescents.     

Attention to 'details': etiquette and the pharmaceutical salesman in postwar American

This paper provides a sketch of the emerging role of the pharmaceutical salesman, or 'detail man', in the growth years of the American post-World War II pharmaceutical industry. Using training manuals, trade literature, in-house company newsletters, memoirs, and a variety of other published sources, the paper follows the delicate tactics employed by salesmen and their managers in their attempts to recast drug salesmanship as a 'professional service' fulfilling vital functions within medical education. As they worked to legitimate their presence in the nation's hospitals and clinics, particular emphasis was given to precise management of the etiquette of doctor-salesman interaction. Ultimately, the techniques employed by mid-century salesmen and their managers were to prove successful in generating a widespread acceptance of the industry representative within the clinical spaces of hospital and clinic. Indeed, many of the practices of market research and market strategy employed across the pharmaceutical industry today have their origins in the practices of the individual detail man. Exploration of the postwar pharmaceutical salesman as an overlooked historical 'type' provides significant insights into the intersection of medicine and the consumer marketplace during the later 20th century.     

Comparison of traditional methods with 3D computer models in the instruction of hepatobiliary anatomy

This study was designed to determine whether an interactive three-dimensional presentation depicting liver and biliary anatomy is more effective for teaching medical students than a traditional textbook format presentation of the same material. Forty-six medical students volunteered for participation in this study. Baseline demographic information, spatial ability, and knowledge of relevant anatomy were measured. Participants were randomized into two groups and presented with a computer-based interactive learning module comprised of animations and still images to highlight various anatomical structures (3D group), or a computer-based text document containing the same images and text without animation or interactive features (2D group). Following each teaching module, students completed a satisfaction survey and nine-item anatomic knowledge post-test. The 3D group scored higher on the post-test than the 2D group, with a mean score of 74% and 64%, respectively; however, when baseline differences in pretest scores were accounted for, this difference was not statistically significant (P = 0.33). Spatial ability did not statistically significantly correlate with post-test scores for the 3D group or the 2D group. In the post-test satisfaction survey the 3D group expressed a statistically significantly higher overall satisfaction rating compared to students in the 2D control group (4.5 versus 3.7 out of 5, P = 0.02). While the interactive 3D multimedia module received higher satisfaction ratings from students, it neither enhanced nor inhibited learning of complex hepatobiliary anatomy compared to an informationally equivalent traditional textbook style approach. .     

A new methodology, an old story? Gender differences in the “draw-a-computer-user” test

Gender differences in computer-related attitudes have been reported in school children of all ages. Females express more negative attitudes than males when asked to explicitly endorse attitude statements. This gender difference may be compounded by females expressing attitudes consistent with their psychological gender. This study uses an art-based methodology to assess the computer-related attitudes of 395 primary school children (aged 5 to 11). A significant difference occurs in the gender drawn by the children. Whilst 30% of females draw males, only 4% of males draw females. Additionally, older females draw proportionally less smiling faces. These results are consistent with more traditional assessments of attitude which indicate that females’ attitudes towards computers become more negative as they progress through the educational system. The art-based methodology also identified similar proportions of females holding negative attitudes as do more traditional assessments, suggesting ecological validity for the gender differences in computer attitudes. The implications for computer-related education are discussed.

Managing a Resident Volunteer Program at a Remote Research Station

Museums are ideal institutions for the development of volunteer programs. A museum's commitments to education and research and to expansion of learning, as well as its physical resources, offer potentially attractive forms of involvement for various segments of the population. We discuss aspects of a long‐established, self‐funded resident volunteer program that integrates the resources of a museum's field station with seasonal staffing needs, resulting in economic benefits to the museum and educational and career‐advancement benefits to volunteers. The practices used to bring together these objectives are discussed, with the goal of providing an example for museum administrators so they might better appreciate the potential diversity of volunteer programs as methods of broadening museums' roles in society.     

When Changing from Merit Pay to Variable/Bonus Pay: What Do Employees Want?

ABSTRACT This study examines potential responses to a change in an employee reward system from permanent merit pay increases to one‐time bonus payments. Removing long term risks associated with escalating pay is an increasingly common compensation strategy. Often overlooked, however, are employee perceptions of reward fairness under such conditions of change. Receiving lump sum payments in lieu of permanent merit pay increase may de‐motivate employees. There has been little or no research conducted on this topic. In this study, using samples of practicing HR managers and university students, an equity questionnaire gathered data on the perceived equivalence between a permanent merit pay increase and what might be demanded by employees as a single payment in its replacement. An analysis of the data collected indicate an approximate 1:2 ratio is needed, such that a proposed lump‐sum payment of $2400 would be perceived as a fair replacement for a permanent merit pay allocation of $1200 per year. Our research indicates that this 1:2 ratio holds for both high and low job satisfaction levels.     

Comparison of physiological responses to graded exercise test performance in outrigger canoeing

The aim of this study was to establish a graded exercise test protocol for determining the peak physiological responses of female outrigger canoeists. Seventeen trained female outrigger canoeists completed two outrigger ergometer graded exercise test protocols in random order: (1) 25 W power output for 2 min increasing by 7.5 W every minute until exhaustion; and (2) 25 W power output for 2 min increasing by 15 W every 2 min to exhaustion. Heart rate and power output were recorded every 15 s. Expired air was collected continuously and sampled for analysis at 15-s intervals, while blood lactate concentration was measured immediately after and 3, 5, and 7 min after exercise. The peak physiological and performance variables examined included peak oxygen uptake (VO2peak), minute ventilation, tidal volume, ventilatory thresholds 1 and 2, respiratory rate, respiratory exchange ratio, heart rate, blood lactate concentration, power output, performance time, and time to VO2peak. There were no significant differences in peak physiological responses, ventilatory thresholds or performance variables between the two graded exercise test protocols. Despite no significant differences between protocols, due to the large limits of agreement evident between protocols for the peak physiological responses, it is recommended that the same protocol be used for all comparison testing to minimize intra-individual variability of results.     

Sunder the Children: Abraham Lincoln's Queer Rhetorical Pedagogy

This essay offers a theory of collective rhetoric derived from a case study of a central rhetorical event of the second wave of feminism, the Redstockings’ 1969 abortion speak-out. A central rhetorical function of consciousness-raising was the collective development of experiential knowledge, and I propose that collective rhetorics are characterized by the collaborative articulation of individual experiences through such rhetorical processes as narrative, irony and humor, and symbolic reversal. I conclude by discussing the importance of collective rhetorical processes in feminist contexts and the potential utility of a theory of collective rhetoric in understanding a range of contemporary discursive forms.
