The disposition in mice of the cannabimimetics JWH-018 and JWH-073 in blood and brain following inhalation of the smoke from the herbal incense product (HIP) "Magic Gold" containing 3.6% JWH-018, 5.7% JWH-073 and less than 0.1% JWH-398 (w/w) is presented. Specimens were analyzed by HPLC/MS/MS. The validation of the method is also presented. Five C57BL6 mice were sacrificed 20 min after exposure to the smoke of 200 mg of "Magic Gold" and a second set of five exposed mice were sacrificed after 20 h. Twenty minutes after exposure to "Magic Gold" smoke, blood concentrations of JWH-018 ranged from 42 to 160 ng/mL (mean: 88 ng/mL ± 42) and those of JWH-073 ranged from 67 to 244 ng/mL (mean: 134 ng/mL ± 62). Brain concentrations 20 min after exposure to "Magic Gold" smoke for JWH-018 ranged from 225 to 453 ng/g (mean: 317 ng/g ± 81) and those of JWH-073 ranged from 412 to 873 ng/g (mean: 584 ng/g ± 163). Twenty hours after exposure to "Magic Gold" smoke, JWH-018 was detected and quantified in only two of the five blood samples. Blood concentrations of JWH-018 were 3.4 ng/mL and 9.4 ng/mL. JWH-073 was detected in only one blood specimen 20 h after exposure at 4.3 ng/mL. Brain concentrations 20 h post exposure for JWH-018 ranged from 7 to 32 ng/g (mean: 19 ng/g ± 9). JWH-073 was not detected in 20 h post exposure brain specimens. JWH-398 was not detected in any of the blood or brain samples. The disposition data presented with the limited data available from human experience provide reasonable expectations for forensic toxicologists in JWH-018 or JWH-073 cases. As with THC after smoking marijuana, blood and brain concentrations of JWH-018 and JWH-073 after HIP smoking can be expected to rise initially to readily detected values, and then drop dramatically over the next few hours to several ng/mL or ng/g, and finally to be at extremely low or undetectable concentrations by 24h apparently due to extensive biotransformation, and redistribution to body fat.  相似文献

A growing number of armed conflicts are ending in negotiated and mediated settlements. While mediation has been acknowledged as an effective means of dispute resolution in many areas, such as family law, medical law and commercial law, it has only quite recently been employed for the resolution of armed conflicts. It is the aim of this article to analyze how mediation was successfully employed in resolving conflicts in the region of Aceh in Indonesia. After 25 years of armed conflict, a peace deal was signed in 2005 between the government of Indonesia and an armed Acehnese group, the Gerekan Aceh Merdeka(GAM). This article will detail the history of the conflict and the mediation process, focusing on the mediation strategies and characteristics.  相似文献

The neighborhood context can interfere with parents’ abilities to effectively monitor their children, but may be related to specific monitoring strategies in different ways. The present study examines the importance of mothers’ perceptions of neighborhood disorganization for the specific monitoring strategies they use and how each of these strategies are related to youths’ alcohol use and delinquency. The sample consists of 415 mother–child dyads recruited from urban and suburban communities in Western New York state. Youths were between 10 and 16 years of age (56% female), and were mostly Non-Hispanic White and African American (45.3 and 36.5%, respectively). Structural equation modeling shows that mothers who perceive greater neighborhood problems use more rule-setting strategies, but report lower levels of knowledge of their children’s whereabouts. Knowledge of whereabouts is related to less youth alcohol use and delinquency through its association with lowered peer substance use, whereas rule-setting is unrelated to these outcomes. Thus, mothers who perceive greater problems in their neighborhoods use less effective monitoring strategies. Prevention programs could address parental monitoring needs based upon neighborhood differences, tailoring programs for different neighborhoods. Further, parents could be apprised of the limitations of rule-setting, particularly in the absence of monitoring their child’s whereabouts.  相似文献

This study examined the extent to which a multiethnic sample of 900 Israeli high school students supported date-rape and victim-blaming attitudes and the predictors of such support. Findings indicate wide support for stereotypes justifying sexual coercion by time and the location of the date, the victim's behavior, and the minimization of the seriousness of date rape. A regression analysis indicates that students' gender and age are the strongest predictors of rape-tolerant and victim-blaming attitudes. Socioeconomic status and religious orientation explain a small proportion of the variance in the support of such attitudes. By contrast, no significant relationship is indicated with ethnicity. Alternative sex-education and rape-prevention programs must address date-rape and victim-blaming attitudes and make students of both genders aware of various factors that continue to be misread as an invitation to have sex and put them at high risk of experiencing sexual coercion on a date.  相似文献

The present study examined adolescents' stressors, coping, and psychological health in the family context in 42 adolescents, ranging in age from 11 to 18. Perceptions of intergenerational stressors and coping strategies were examined for congruence by comparing adolescents' self-reports to parents' reports on their adolescents. Adolescents' reports on their parents were also compared to parents' reports on themselves. This study also specified family environment dynamics in relation to the study variables. Hypotheses that more congruent adolescent and parent perceptions about each other's stressors and coping were related to more cohesive family environments and more adaptive copings were generally supported. Family environment variables and congruent coping were related to psychological health symptoms as well. The findings contribute to current knowledge about the study variables examined in the context of the family.  相似文献

Child neglect, the failure to adequately meet a youngster's care needs, is the most frequent form of child maltreatment reported to welfare authorities. However, there have been few empirical reports of treatment outcomes for adjudicated, child neglectful parents. In the current study, an initial assessment of three neglectful parents revealed substantial deficits in cognitive problem-solving skills related to child care judgment. Treatment, consisting of modeling, shaping, practice, and feedback was used to improve each parent's child care problem-solving skills in a multiple baseline design. Skill enhancement was also found for untrained (generalization) problem situations, and independent caseworker ratings of each family's functioning provided external validation of the intervention's clinical impact.  相似文献
