Music,rowing, and the aesthetics of rhythm

Having “good rhythm” is essential in both music and competitive rowing, but what exactly constitutes “good rhythm,” and how do we achieve it? Although rhythm is often discussed in purely auditory terms, I argue that rhythm is fundamentally a multisensory, kinesthetic phenomenon. By drawing parallels between music and rowing, I illustrate how biological motion principles underlie the parameters of rhythm in both disciplines, and how the cognition and appreciation of rhythm is deeply embodied. I suggest that the two main ways in which rhythms generate pleasure in both music and rowing are by enabling behavioral synchrony between individuals, and by engaging the body in the cognitive process of rhythm perception and prediction. In essence, “good rhythm”—a rhythm that is enjoyed and appreciated—is rhythm that moves.     

中国是素食者的地狱吗

刚来北京时，我是个素食主义者。这一点从我16岁以后就一直没变过，而且我也从没有过要改变的打算。可来到中国后我很快就意识到，“素食阶段”无法再继续了。     

Cigarette smoking and cessation among trade or technical school students in Texas

Although students enrolled in trade or technical colleges are at an elevated risk for tobacco use, virtually no information exists regarding their smoking behaviors. OBJECTIVE AND PARTICIPANTS: In the present study, the authors examined (1) the prevalence of smoking and quitting among 617 students in 2 trade or technical colleges in East Texas and (2) on-campus media exposure to antitobacco messages. METHODS: Students voluntary completed the 42-item Texas Trade and Technical School Tobacco Survey during a required introductory-level class. RESULTS: Of the participating students, 34% reported past-30-day smoking (current smoking). Of current smokers, 74% reported a previous quit attempt and 64% wanted to quit before graduation. Although most current smokers expressed a desire to quit smoking, the antitobacco message they were least likely to see on campus was that regarding how to quit. Current smokers cited their own health as the most likely reason to quit smoking, and most reported wanting to quit on their own, without the use of resources. However, of the 9 listed resources, students were most likely to report the possible use of medication. CONCLUSIONS: Given that most smoking students desire to quit smoking--and that they are enrolled in trade or technical schools for an extended period of time--additional research should examine how successful interventions can be delivered at the trade or technical school itself.     

Comparison of Advance Medical Directive Inquiry and Documentation for Hospital Inpatients in Three Medical Services: Implications for Policy Changes

Following the introduction of the Patient Self-Determination Act of 1990, the Veterans Health Administration developed its own advance medical directive (AMD) policy, which most recently states that documentation is mandatory for all hospital patients in all settings. The object of this study was to assess the effectiveness of AMD documentation at a local Veterans Affairs Medical Center. AMD documentation was compared among three inpatient services: surgery, medicine, and psychiatry. Retrospective in nature, 594 inpatient cases were compared. Results revealed that, overall, the rate of AMD documentation was 37.7%. AMD documentation on surgery was statistically more frequent (45.6%) than for either medicine (33.2%) or psychiatry (34.5%). The difference between the numbers of days to AMD documentation for all three services was not statistically significant. While there was no statistically significant difference across gender, Caucasians had AMDs documented more frequently than African Americans (p < .001). Logistic regression reveals that social worker and physician intervention, not patient-specific variables, are the primary predictors of AMD incidence. Policy makers may need to consider the realities of hospital care, especially in emergency settings, and be more specific in the steps of implementation of the policy in the evenings, weekends, and holidays. True adherence to policy implementation may require hospital administrators to increase staff and educational efforts so that the concept of AMD communication and documentation is completely explained to all staff and patients. Policy should include an electronic record reminder that is renewed every 3 years and provisions for accommodating patients who arrive on weekends and holidays, with special awareness of the particular communication needs of minority groups. The study conclusions are that further inquiry is needed to understand these policy nuances to enable the Veterans Affairs Administration to improve its policies and performance in this important aspect of healthcare.     

Multimedia Benchmarking Analysis for Three Risk Assessment Models: RESRAD, MMSOILS, and MEPAS

This paper is one in a series that describes results of a benchmarking analysis initiated by the Department of Energy (DOE) and the United States Environmental Protection Agency (EPA). An overview of the study is provided in a companion paper by Laniak et al. presented in this journal issue. The three models used in the study—RESRAD (DOE), MMSOILS (EPA), and MEPAS (DOE)—represent analytically-based tools that are used by the respective agencies for performing human exposure and health risk assessments. Both single media and multimedia benchmarking scenarios were developed and executed. In this paper, the multimedia scenario is examined. That scenario consists of a hypothetical landfill that initially contained uranium-238 and methylene chloride. The multimedia models predict the fate of these contaminants, plus the progeny of uranium-238, through the unsaturated zone, saturated zone, surface water, and atmosphere. Carcinogenic risks are calculated from exposure to the contaminants via multiple pathways. Results of the tests show that differences in model endpoint estimates arise from both differences in the models' mathematical formulations and assumptions related to the implementation of the scenarios.
