Body Perceptions, Weight Control Behavior, and Changes in Adolescents’ Psychological Well-Being Over Time: A Longitudinal Examination of Gender 总被引:1,自引:0,他引:1
Anastasia S. Vogt Yuan 《Journal of youth and adolescence》2010,39(8):927-939
This study used the National Longitudinal Study of Adolescent Health to explore gender differences in the relationship between body perceptions and behavior and changes in adolescents’ psychological well-being over a one-year time period. The sample included 12,814 adolescents (51% girls) aged 11–20 comprised of 68% Non-Hispanic White, 15% African American, 12% Hispanic, and 4% Asian. Perceptions of being larger or more developed generally decreased girls’ psychological well-being over time. Body perceptions and behavior did not significantly influence changes in boys’ psychological well-being over time. Non-Hispanic White girls were the most influenced and Non-Hispanic White boys were the least influenced by body perceptions and behavior. Perceived relative development influenced early adolescent girls, whereas perceptions of being overweight influenced middle to late adolescent girls. Additionally, trying to lose weight influenced middle adolescent boys and girls. These results imply that body perceptions and behavior disadvantage girls’ psychological well-being relative to boys during adolescence. 相似文献

Four cases of fatal intoxications with caffeine are described. Caffeine is widely available in beverages and in different OTC-products, in many of them in combinations with other drugs like ephedrine. Caffeine is not as harmless as one might believe. An overdose of caffeine alone, intentional or not, might be deadly. It seems to be warranted to include caffeine in the drug-screening of forensic autopsy cases. It is not motivated from a medical point of view to sell pure caffeine over the counter. 相似文献

Why did New Zealand adopt one of the most neoliberal tax systems in the world, whereas Ireland pursued a heterodox tax policy of low rates, deep deductions, and distortionary tax incentives? The diverging tax policy trajectories of these two small liberal market economies since 1980 are not well accounted for by conventional ideational, partisan, or political‐institutional explanations. The article argues that the varying degree of neoliberal reform is better understood as the result of differences in the institutionalization of economic knowledge within the state. Distinct administrative institutions in New Zealand and Ireland gave rise to profound differences in the identities, expertise, economic ideas, and policy advice approach of tax policy bureaucrats, which had a major impact on tax policymaking in the two countries. 相似文献

This paper considers the devolution of authority to public school governing bodies (SGBs) in the context of self-managing schools. It examines the nature of the powers, functions and duties assigned to them in legislation and asks whether the manner in which South African legislation provides for the devolution of authority and power represents authentic devolution of power, or whether it can be characterised as centralisation in disguise. The question is answered by examining, against the backdrop of general and education-specific legal provisions, two examples of functions of SGBs, namely those to determine language and admission policies. 相似文献

Buprenorphine is considered to have little respiratory side effects at therapeutic doses and the partial agonistic properties should produce a "ceiling effect" for respiratory depression at higher doses. Still, there are several reports on buprenorphine related deaths. Most deaths involve drug users and the co-administration of other CNS depressant drugs as well as reduced tolerance have been suggested to be risk factors. The primary aims were to investigate if lack of tolerance and/or co-ingestion of other psychotropic drugs are significant risk factors in buprenorphine fatalities. From July 2005 to September 2009, all autopsy cases where buprenorphine or norbuprenorphine had been detected in femoral blood and where analysis of buprenorphine had been performed in urine were selected. Results from the postmortem examination and toxicology were compiled. Postmortem toxicology was performed using the routine methodology at the laboratory. In total, 97 subjects were included in the study. These were divided into four groups; Intoxication with buprenorphine (N=41), Possible intoxication with buprenorphine (N=24), Control cases where buprenorphine was not the cause of death (N=14), and Unclear (N=18). The metabolite to parent compound ratios in both blood and urine in the Intoxication group were significantly different from those in the Control and Unclear groups. An extensive poly-drug use was seen in all groups with several additional opioids in the Possible group (54%) and in the Unclear group (78%) and hypnotics or sedatives in more than 75% of the Intoxication, Possible, and Unclear cases. Illicit drugs were present in all groups but not to a great extent with amphetamine and tetrahydrocannabinol as the main findings. Interestingly, 4 cases in the Intoxication group presented with no other significant drugs in blood other than buprenorphine. We conclude that a lethal concentration of buprenorphine in blood cannot be defined. Instead the analysis of blood as well as urine can be an important tool to show that the drug was taken shortly before death and to rule out a continuous use of buprenorphine supporting the notion that abstinence is an important risk factor. The presence of alprazolam in more than 40% of the Intoxications and the presence of hypnotics and sedatives in 75% of the Intoxications suggests that these drugs interact with buprenorphine producing toxic effects that buprenorphine alone would not have produced. Still, in 10% of the Intoxications no other drugs were found indicating that under certain circumstances buprenorphine alone may produce respiratory depression resulting in death. 相似文献

Money laundering regulations have become stricter over time and involve more and more actors. This means that the accountability
of laundering regulation will become more important; theoretically, money laundering should have decreased with the implementation
of new regulations. However, as this paper shows, it is difficult to estimate even the sign of the trend in the proceeds of
crime and of laundering over time with particular reference to the drug trade. There seems to be a substitution from hard
to softer drugs, and no substantial decline in the proceeds of crime and likewise no substantial decline in money laundering.
Criminals seem to switch from the more controlled banking sector into still less controlled parts of financial markets, and
from financial markets to other sectors. These new sectors include electronic payments, trade and real estate. The paper shows
how one can empirically approach the latter two by using economic information of unusual prices and other characteristics
in order to identify the amount of laundering in these sectors. Combining economic information with criminological data facilitates
the development of a new tool for identifying money laundering in some important sectors. 相似文献
