The theory of sensation seeking has conceptualized this construct as a stable personality trait associated with a variety
of problem behaviors. Reckless behavior theory posits that increases in reckless behavior during adolescence can be attributed,
in part, to increases in sensation seeking. This study evaluated patterns of stability and change in sensation seeking among
868 urban, minority youth (53% female), followed longitudinally across middle school (6th–8th grades). Group-based trajectory
analysis identified a stable low group (20%), a moderate increasing group (60%), and a stable high group (20%) each of which
demonstrated unique associations with changes in problem behaviors. Stable low sensation seekers reported consistently low
levels of aggression, delinquency, and substance use across middle school. Moderate increasing sensation seekers reported
significant increases in these risk behaviors over time from levels near zero in the 6th grade. Stable high sensation seekers
reported high, stable levels of aggression and delinquency upon entry into middle school as well as significant increases
in substance use across middle school. These results lend support to both theories and highlight a need for caution when categorizing
adolescents as high or low sensation seekers. 相似文献

In spite of major coverage expansions under the Patient Protection and Affordable Care Act (ACA), a large proportion of immigrants will continue to remain outside the scope of coverage. Because various provisions of the ACA seek to enhance access, advancing knowledge about immigrant access to health care is necessary. The authors apply the well‐known Andersen model on health care access to two measures—one focusing on perceptions of unmet health care needs and the other on physician visits during the last year. Using data from the New Jersey Family Health Survey, the authors find that prior to implementation of the ACA coverage expansions, immigrants in New Jersey reported lower levels of unmet health care needs despite poorer self‐rated health compared with U.S.‐born residents. The article concludes with a discussion of the use of Andersen model for studying immigrant health care access and the broader implications of the findings. 相似文献

The Patient Protection and Affordable Care Act (ACA) requires that adults up to age twenty-six be permitted to enroll as dependents on their parents' health plans. This article examines the experiences of states that enacted dependent expansion laws. Drawing on public information from thirty-one enacting states and case studies of four diverse reform states, it derives lessons that are pertinent to the implementation of this ACA provision. Dependent coverage laws vary across the states, but most impose residency, marital status, and other restrictions. The federal Employee Retirement Income Security Act further limits the reach of state laws. Eligibility for expanded coverage under the ACA is much broader. Rules in some states requiring or allowing separate premiums for adult dependents may also discourage enrollment compared with rules in other states (and the ACA), where these costs must be factored into family premiums. Business opposition in some states led to more restrictive regulations, especially for how premiums are charged, which in turn raised greater implementation challenges. Case study states did not report substantial young adult dependent coverage take-up, but early enrollment experience under ACA appears to be more positive. Long-term questions remain about the implications of this policy for risk pooling and the distribution of premium costs. 相似文献

Five cases of vehicular homicide are presented in which the determination of an occupant's role in a motor vehicle collision was an important medicolegal question. The identification of the occupant's role in a motor vehicle collision can be determined by the forensic pathologist. The investigation that coordinates an examination of injury mechanisms, occupant kinematics, vehicle dynamics, and trace evidence will facilitate such a determination. This determination protects the innocent passenger, when faced with criminal or civil charges, from being falsely prosecuted as the driver. The examination of the above-mentioned components in a multi-occupant collision takes on particular forensic importance when a surviving driver claims to be a passenger: the victim rather than the assailant. 相似文献

Fetal death due to acute carbon monoxide poisoning is rarely reported in the medical literature. Of the eight cases found in literature review, only one documented the fetal carboxyhemoglobin concentration. This paper reports a fetal death due to accidental nonlethal maternal carbon monoxide intoxication in which both maternal and fetal carboxyhemoglobin concentrations were obtained. The corrected carboxyhemoglobin concentration was 61% at the time of death in utero, while the maternal carboxyhemoglobin was measured at 7% after one hour of supplemental oxygen. The authors review the mechanisms of fetal death and emphasize the different carbon monoxide kinetics in the fetal circulation. 相似文献
