论从药品到毒品的“角色”转换 总被引：1，自引：0，他引：1
王新华 《医学与哲学(人文社会医学版)》2007,28(9):75-77
毒品与药品有着密不可分的联系,毒品来源于药品但又不同于药品。具有依赖性的药品一旦流入非管制渠道,用于非医疗目的,在社会上泛滥便成为毒品。因此,对有依赖性的药品需要严格管理并合理地使用。 相似文献

Non-visual gaze patterns (NVGPs) involve saccades and fixations that spontaneously occur in cognitive activities that are not ostensibly visual. While reasons for their appearance remain obscure, convergent empirical evidence suggests that NVGPs change according to processing requirements of tasks. We examined NVPGs in tasks with long-term memory (LTM) and working memory (WM) requirements. Experiment 1 yielded significantly higher eye movement rate (EMR) in tasks requiring LTM search than in a WM task requiring maintenance of information. Experiment 2 manipulated accessibility of items in study-test episodic tasks using the levels of processing paradigm. EMR was high in episodic recall irrespective of item accessibility. Experiment 3 examined functional significance of saccades in LTM tasks. Voluntary saccadic suppression produced no evidence that saccades contribute to task performance. We discuss the apparent epiphenomenal nature of spontaneous saccades from an evolutionary perspective and outline a neuroanatomical model of the link between the saccadic and memory system. 相似文献

Past literature has documented a linkage between entitlement and interpersonal tension, primarily in romantic relationships. However, there is a lack of research investigating the impact of entitlement on sibling relationships. Guided by the agency model of narcissism and adult development literature, this study conceptualized relational entitlement as one form of state narcissism and examined the actor and partner effects of relational entitlement on perceived sibling conflict as well as the moderating effects of financial dependence on parents. Participants were 136 emerging adult sibling dyads (older sibling Mage = 22.20, SD = 2.35; younger sibling Mage = 19.54, SD = 1.55). Results indicated that younger siblings' (not older siblings') relational entitlement was positively associated with both their own and their siblings' perceptions of conflict. Moreover, younger siblings' financial dependence buffered the actor association between younger siblings' relational entitlement and perceived conflict. These findings suggest that emerging adult siblings' developmental status of financial dependence provides a nuanced context for understanding the actor and partner effects of relational entitlement on sibling conflict. The discussion focuses on the role of self-inflated social comparison in emerging adult sibling conflict and how the developmental characteristics of older and younger siblings shape the above associations. 相似文献

Using a novel approach, in this work, we establish an association between self-reported compliance with COVID-19 preventive behaviors and fear of the virus with morbidity rates (i.e., actual tests and their outcome). In two nationally representative samples that were collected in Israel during the first (April 2020: N = 507) and second (August 2020: N = 515) waves of the COVID-19 pandemic, participants responded to items assessing their compliance with the COVID-19 preventive behaviors and their fear of contracting the virus. Participants' compliance and fear self-reports served as a proxy for morbidity rates. Specifically, we assessed the association between sociodemographic variables (gender, age, or belonging to a minority group), self-reports, and morbidity rates (as reported in publicly open databases of the Israeli health ministry). We found that self-reports of compliance and fear were mirrored and aligned with actual morbidity rates across sociodemographic variables and studies. By establishing a clear connection between specific behavior (i.e., compliance with covid regulations) and emotion (i.e., fear of getting infected by the virus), self-reports and sociodemographic variables represent a real related phenomena (i.e., covid 19 morbidity rates), our findings overall validate numerous studies that used self-reports to assess compliance with COVID-19 preventive behaviors. 相似文献

This systematic review of articles published in 4 counseling journals found 207 articles that used online recruitment, of which 98 (47.3%) reported a response rate. These 98 studies collectively contained 22,466 individual participants. Results showed that nearly one third of all empirical articles used online recruitment, and the average response rate was 34.2% (SD = 22.6). Response rates are further described by journal, population, research methodology, and recruitment strategy. Researcher‐reported issues with online recruitment and data collection were also analyzed qualitatively, and recommendations for researchers are discussed. 相似文献

Concepts from behavioral momentum theory, along with some empirical findings, suggest that the rate of baseline reinforcement may contribute to the relapse of severe destructive behavior. With seven children who engaged in destructive behavior, we tested this hypothesis in the context of functional communication training by comparing the effects of different baseline reinforcement rates on resurgence during a treatment challenge (i.e., extinction). We observed convincing resurgence of destructive behavior in four of seven participants, and we observed more resurgence in the condition associated with high‐rate baseline reinforcement (i.e., variable‐interval 2 s in Experiment 1 or fixed‐ratio 1 in Experiment 2) compared to a low‐rate baseline reinforcement condition. We discuss the implications of these results relative to schedules of reinforcement in the treatment of destructive behavior and strategies to mitigate resurgence in clinical settings. 相似文献

Motor vehicle collisions are the leading cause of death in people ages 5–34 in the US, and secondary task engagement, such as talking on a cell phone, is a leading contributor to motor vehicle collisions. The negative effects of secondary task engagement on driving performance has become a prominent recent topic of study given the increasing amount of time drivers engage in distracted driving. However, few studies have examined the effects of secondary task engagement while driving on health related outcomes such as cardiovascular reactivity. Cardiovascular reactivity, as measured by heart rate and blood pressure, has been used in previous studies as a means of measuring effort in task engagement as well as a means to predict cardiovascular disease and stroke. This study investigates the effect of secondary task (talking on a cell phone, texting, and driving with no task) while driving in a simulator on cardiovascular reactivity. Using difference scores between baseline (a period of inactivity) and stimulus (driving with no task and driving with secondary tasks), a repeated measures analysis of variance using a mixed model approach was used to determine the effect of secondary task on cardiovascular reactivity. Findings indicated that talking on a cell phone while driving significantly increased cardiovascular reactivity via heart rate and blood pressure compared to driving with no task. Texting while driving did not differ significantly from driving with no task. This study demonstrates the need for more research on the long term effects of secondary tasks while driving on cardiovascular reactivity and for assessing the risks associated with secondary task use while driving on developing cardiovascular disease or stroke. 相似文献
