Adolescent nutritional and psychological patterns and risk for the development of an eating disorder
Gloria R. Leon Ph.D. Professor Director of Clinical Psychology Cheryl L. Perry Ph.D. Associate Professor Director of Community Health Education Carolyn Mangelsdorf M. A.

A group of 256 female and 248 male adolescent students were assessed regarding nutritional practices and psychological attitudes associated with the development of eating disorders. While the majority showed adequate nutritional practices, there was a high prevalence of dieting and the consumption of low-calorie foods among the girls. For boys, there was no relationship between a strong desire for thinness and restriction of foods high in calories; boys tended to report that hunger and positive affective states were related to overeating. A risk factor conception of nutritional and psychological precursors to the later development of an eating disorder was discussed.This research was supported in part by a Biomedical Research Support Grant to Dr. Cheryl Perry. 相似文献

Legal context. Some state legislatures are considering billswhich would require those applying for a drivers licenceto provide one or more biometric identifiers. The US federalgovernment is tending towards eavesdropping on conversationsand investing in data mining efforts while on the other handanti "big-brother" technologies are also emerging to counterthis trend and protect privacy. The demand for technology toprotect privacy will no doubt increase as the demand for defenceand security spending increases. We also live in a world wherebioterrorist acts are a constant threat and therefore demandfor biological detection devices and nanotechnology is growingdaily. Key points. Current technology advances in biometrics, surveillance,biological detection and nanotechnology can be used both toprotect and to jeopardize the security and privacy of individuals.As such, the importance of intellectual property in these areascannot be underestimated. Practical significance. Companies are advised to go onthe offensive. All companies should aggressively protecttheir core technology in numerous facets such as patent protection,copyright, trade marks and trade secrets. In the high tech arenathis is especially important because the demand for securityand privacy necessitates the development of advanced applicationsand in turn the quality of protectable IP for the companiesthat develop the technology increases. Additionally, companiesshould also pursue an offensive strategy that includes analyzingemerging standards and competitor focus so that they can acquirea competitive advantage or secure cross-licensing of anotherstechnology. 相似文献

Kawasaki disease (KD) primarily affects infants and is rarely fatal in young adults. The sequelae of KD can result in death months to years after the exposure to the causative agent. Such deaths are defined as Stage IV KD, which is characterized by the formation of multiple aneurysms in the coronary arteries, calcification and recanalization of the obstructed portions of the coronary arteries, and myocardial infarction and ischemia. A 10-year retrospective review of sudden deaths in Allegheny County, Pennsylvania, identified two fatal cases of Stage IV KD involving young adults. These two young adults were healthy and completely asymptomatic; they had no identifiable risk factors for cardiovascular disease before the fatal event. One adult was involved in vigorous exercise, and the other was recumbent in bed at the time of death. 相似文献

During the interaction between a criminal suspect and a law enforcement officer, the risk of death to the suspect, police, or civilians is increased. Unfortunately, very little information is available on the death risks arising from this interaction. This study provides an assessment of the risk of death to law enforcement officers, suspects, and bystanders by separating the interactions into the following 4 phases: (1) events prior to and during arrest; (2) police pursuits or chases; (3) transport of the suspects; and (4) during incarceration. A 5-year (1994-1998) retrospective coroner-based study of all deaths that occurred during these 4 phases was conducted in Allegheny County, Pennsylvania. A total of 77 cases were identified; 14 deaths (18.1%) occurred prior to or during arrest, 10 (12.9%) during police chases, 2 (2.6%) occurred while the actors were being transported, and 51 (66.2%) during incarceration. The majority of cases (98.7%) were males, blacks (63.6%), and single (50.6%). The respective risks of death by phase were prearrest/arrest, 6.5 per 100,000 arrests; transport, 0.93 deaths per 100,000 arrests; and incarceration, 268 deaths per 100,000 inmates. Study showed the following: (1) risk of death to offenders was greatest during police pursuits; (2) the risks during arrests are not insignificant and involved an officer being threatened with a weapon in one-third of the events; and (3) deaths among inmates were primarily due to natural causes. 相似文献

A recent large firm-level dataset is analysed to compare labour indicators of privatised, private, and public firms around the world, in particular differences relating to wages, benefits, labour composition, education and training, unionisation, and quality of management. We find that labour productivity and the ratio of permanent to temporary workers increase after privatisation. 相似文献

Expertise literature in mainstream cognitive psychology is rarely applied to criminal behaviour. Yet, if closely scrutinised, examples of the characteristics of expertise can be identified in many studies examining the cognitive processes of offenders, especially regarding residential burglary. We evaluated two new methodologies that might improve our understanding of cognitive processing in offenders through empirically observing offending behaviour and decision-making in a free-responding environment. We tested hypotheses regarding expertise in burglars in a small, exploratory study observing the behaviour of ‘expert’ offenders (ex-burglars) and novices (students) in a real and in a simulated environment. Both samples undertook a mock burglary in a real house and in a simulated house on a computer. Both environments elicited notably different behaviours between the experts and the novices with experts demonstrating superior skill. This was seen in: more time spent in high value areas; fewer and more valuable items stolen; and more systematic routes taken around the environments. The findings are encouraging and provide support for the development of these observational methods to examine offender cognitive processing and behaviour. 相似文献
