Synthetic tryptamines have gained popularity for their hallucinogenic properties, unscheduled status, and availability from “head shops” and through the internet. Here, we present a case of synthetic tryptamine‐induced delirium secondary to 5‐MeO‐DALT ingestion in a previously healthy young male. 5‐MeO‐DALT led to the hospitalization of our patient after ingestion of a standard dose, presenting with extreme agitation, tachycardia, diaphoresis, and combativeness leading to physical restraint and intravenous sedation. A search of PubMed, Ovid, and Google Scholar for keywords of “5‐MeO‐DALT,” “5‐methoxy‐N,N‐diallyltryptamine,” or “Lucy‐N‐Nate” found no case reports or clinical articles in the literature. Rapid emergence and commercialization of this novel synthetic tryptamine 5‐MeO‐DALT points to the importance of health care and forensic professionals keeping abreast of the latest drugs of abuse and their clinical features. The authors hope this report leads the way in disseminating the potential risks associated with unscheduled and unregulated substances, synthetic tryptamines such as 5‐MeO‐DALT in particular.  相似文献

In many European countries, municipalities are becoming increasingly important as providers of electronic public services to their citizens. One of the horizons for further expansion is the delivery of personalised electronic services. In this article we describe the diffusion of personalised services in the Netherlands over the period 2006–2009 and investigate how and why various municipalities adopted personalised electronic services. In achieving this, we analyse data that were gathered during interviews with key stakeholders in 10 selected Dutch municipalities. We synthesise the findings in an explanatory model of personalised electronic service delivery diffusion. The model emphasises persuasive pressures that are channelled to potential adopters of personalised services. Furthermore, the model shows how persuasive pressure (as perceived by adopters) is followed-up by organisational search activities, and how, in various circumstances, the idea of personalised services is ‘framed’ by innovation champions, knowledge brokers and new members of staff as to appeal to specific organisational priorities and ambitions. In doing so, this article contributes to an institutional view on adoption and diffusion of innovations, in which (1) horizontal and vertical channels of persuasion and (2) human agency, rather than technological opportunity and rational cost-benefit considerations, account for actual diffusion of innovations.  相似文献

In the wake of several high-profile libel actions brought by U.S. celebrities and foreign businessmen in London because of more favorable defamation laws there, London was dubbed the “libel tourism capital of the world.” The U.S. response in 2010 was the passage of the SPEECH Act, preventing courts from enforcing libel judgments from foreign jurisdictions not providing the same level of protection as the United States. Similarly, in 2013 the United Kingdom responded to international and national criticism by passing the Defamation Act to address the loophole in its system that caused the abuse. Both acts have been criticized, the first for its aggressiveness, and the second for its conservative nature. This article examines the development of the law of defamation in the two jurisdictions and analyzes the content of both statutes, along with their criticisms, proposing international cooperation to address the issue of libel tourism.  相似文献

This study develops a structural equation model to describe the effect of two groups of factors (type of commitment and play context) on the violence experienced during intimate partner conflict. After contrasting the model in adolescents and university students, we have confirmed that aggressive play and the simulation of jealousy and anger increase the risk of dating victimization during conflicts through the negative reactions that they cause. Where commitment is concerned, the results are different according to whether commitment is personal or constraining. The former provides protection against dating victimization, reducing risk in the play context, whereas the latter has no effect on the violence experienced but facilitates a more dangerous play dynamic. The model can be applied in the design of programs to prevent dating violence.  相似文献

Exposure to neighborhood violence is an important risk factor for the social and emotional development of children and youth. Previous work recognizes that violence may affect children indirectly via secondhand exposure; yet, few studies have aimed to identify and quantify these effects, especially in settings like Colombia where youth is chronically exposed to violence. To address this gap in the literature, this article implements an empirical strategy where geographically specific and time-stamped data are leveraged to identify the effect of indirect exposure to homicides on fifth grade children’s social and emotional outcomes. Sample participants (N?=?5801) represent the fifth-grade population of boys and girls (50.7%) in two major urban areas in the country (Mage?=?11.01, SD?=?0.75). We hypothesize that the effects of exposure to neighborhood violence on children’s social and emotional skills will be consistent and negative. The findings indicate a consistent negative effect of indirect exposure to homicides on children’s emotional functioning (i.e., emotional regulation and empathy), as well as on the prevalence of avoidance behaviors. However, contrary to theoretical expectations, the results do not support effects on children’s levels of aggressive behavior, nor on the beliefs and attitudes that justify the use of aggression in interpersonal relationships. The findings are discussed in light of predictions from social cognitive models and their implications for developmentally and trauma-informed interventions for youth.  相似文献

This study examined the longitudinal consistency of mother–child reporting discrepancies of parental monitoring and whether these discrepancies predict children’s delinquent behaviors 2 years later. Participants included 335 mother/female-caregiver and child (46% boys, >90% African American; age range 9–16 years [M = 12.11, SD = 1.60]) dyads living in moderate-to-high violence areas. Mother–child discrepancies were internally consistent within multiple assessment points and across measures through a 2-year follow-up assessment. Further, mothers who at baseline consistently reported higher levels of parental monitoring relative to their child had children who reported greater levels of delinquent behaviors 2 years later, relative to mother–child dyads that did not evidence consistent discrepancies. This finding could not be accounted for by baseline levels of the child’s delinquency, maternal and child emotional distress, or child demographic characteristics. This finding was not replicated when relying on the individual reports of parental monitoring to predict child delinquency, suggesting that mother–child reporting discrepancies provided information distinct from the absolute frequency of reports. Findings suggest that mother–child discrepancies in reports of parental monitoring can be employed as new individual differences measurements in developmental psychopathology research.  相似文献

The daily emotional experiences of adolescents are dynamic, vary significantly across individuals, and are crucial to their psychological adjustment, warranting a need to identify factors that promote adaptive affective responses to stressors and attenuated affective instability. The objective of this study, therefore, was to examine protective factors linked to individual differences in daily affective reactivity and instability utilizing a daily diary design in a national sample of 100 U.S. adolescents (13–17 years; 40% girls; 79% White). Adolescents completed a baseline survey and then 14 daily online surveys. Better mother-adolescent communication predicted lower negative affect reactivity, whereas greater use of problem-focused coping strategies predicted higher positive affect reactivity. Greater trait resilience and instrumental support seeking predicted lower negative affect instability. Conversely, more emotional support seeking predicted higher negative affect instability. No factors were associated with positive affect instability, and father-adolescent communication was unrelated to daily affective reactivity and instability. The findings implicate specific protective factors associated with distinct aspects of affective reactivity and instability.
