感知价值、满意度与继续使用意向—基于3G用户的实证研究

本文考察感知价值、满意度对继续使用意向的作用机理。基于相关理论与实证研究,我们首先提出3G用户继续使用意向概念模型与研究假设,然后通过实证研究对假设进行检验。研究结果表明感知价值和满意度决定继续使用意向。满意度是继续使用意向最强的预测因子。感知有用性和感知使用成本既直接作用于继续使用意向,也通过满意度间接作用于继续使用意向。感知易用性和感知形象提升直接作用于继续使用意向,而不需要通过满意度的中介作用。     

Effects of cognitive-behavioural therapy on anxiety,depression and condom use in people with HIV in Mexico City: a pilot study

Anxiety and depression in people living with HIV (PLWH) are negatively associated with healthy sexual behaviours. We pilot-tested a Cognitive-Behavioural Therapy (CBT)-based intervention to reduce anxiety and depression, aimed to increase serostatus disclosure to sexual partners, quality of sexual life (QoSL) and condom use. The study had a single-case experimental design (AB) with follow-up measures. Eleven PLWH with moderate/severe anxiety/depression received six-module CBT intervention delivered in ten one-hour individual weekly sessions. Anxiety, depression, consistent/correct condom use and QoSL were measured. Depression and anxiety decreased after the intervention (depression baseline [BL] Mdn = 21, final [F] Mdn = 3, z = -2.934, p = .003; anxiety BL Mdn = 30, F Mdn = 4, z = -2.941, p = .003). QoSL improved (BL Mdn = 28, F Mdn = 13, z = -2.625, p = .009), along with participants’ ability to use condoms (57.14 vs.100, z = -2.937, p = .003). Effect size was large, changes were maintained at follow-up measurements. The CBT intervention had positive effects in reducing anxiety and depression, which could facilitate the acquisition of healthy sexual behaviours. Further studies are important to clarify the benefits of targeting emotional variables to improve wellbeing and prevention behaviours in PLWH.     

Alcohol use among adults in Kenya: Results from the National Non-Communicable Diseases Risk Factor survey, 2015

The aim of this study was to assess the prevalence and correlates of alcohol use among Kenyan adults. We analysed data from the Kenya cross-sectional national Non-Communicable Diseases Risk Factor survey, 2015. The survey sampled 4 469 adults (median age 38.0 years, interquartile range = 23, age range of 18–69 years). Results indicate that 6.7% were hazardous or harmful alcohol users and 12.8% past month binge-drinkers. In adjusted logistic regression analysis, being male, middle aged, belonging to the Luhya or Kalenjin ethic group, tobacco use, and having hypertension increased the odds for hazardous or harmful alcohol use. Socio-demographic and health factors appear to influence risk for hazardous or harmful alcohol use among adults in Kenya.     

转移方式对基于劳动的物品所有权判断的影响

劳动在人们的所有权判断中起着重要作用。以往研究虽然考察了幼儿和成人基于劳动的所有权判断,但却忽视了原材料转移方式的作用,且大部分集中在西方国家。本研究以中国3～5岁的幼儿和成人为对象,考察了他们在拿和借两种转移方式下基于劳动的所有权判断。结果发现,4～5岁的幼儿及成人在两种转移方式下的所有权判断存在显著差异。相比于拿条件,他们在借条件下不太倾向于判断劳动者是新加工物品的所有者。4～5岁幼儿在拿条件下更倾向认为劳动者是新加工物品的所有者,而成人在两种条件下都倾向于支持原材料占有者是新加工物品的所有者。3岁幼儿在两种转移方式下的所有权判断不存在显著差异,且不支持任何一方。结果提示,转移方式会影响个体基于劳动的所有权判断,并且从4岁开始幼儿能够区分不同转移方式的作用。     

Covenant,blood, and violence: America at war with itself and others

Religious nationalism is dangerous, because it tends toward violence. In the case of America, religious nationalism is preceded by, and dependent upon, a covenant with God that renders judgment against the nation when it fails to embody divine justice. The second use of the law in Lutheran theology, combined with René Girard's scapegoat theory, provides the prophetic public theologian with a searchlight to make visible the nation's justification of violence. The haunting question becomes this: should the prophetic public theologian expose the lie on which American religious nationalism is built and risk sundering human community?     

Testing the properties of the triarchic model of psychopathy in a community sample: Self‐reported trait aggression and drug consumption associations

The triarchic model of psychopathy encompasses different conceptions of psychopathic personality characterized by three phenotypic components: boldness, disinhibition, and meanness. Psychopathy is a complex construct at both emotional and behavioral level. The aim of this study was to determine the core elements of psychopathic personality in a community sample and analyze the relation between these elements and other personality traits such as aggression, and certain specific behavioral manifestations such as substance use. The study sample comprised 1,159 participants aged between 17 and 74 years, who were administered the Triarchic Psychopathy Questionnaire, the Impulsive‐Premeditated Aggression Scale, and the Aggression Questionnaire. The results show that the constructs of meanness and disinhibition are more highly associated with different forms of both impulsive and premeditated aggression. Furthermore, men scored higher on all three components of the triarchic model compared to women. Finally, higher substance use (tobacco and drugs) was associated with higher scores in meanness, boldness, and disinhibition. These findings demonstrate the importance of assessing psychopathy in a community sample, and the detection of possible risk factors for the disorder.     

Evidence‐Based Human Trafficking Policy: Opportunities to Invest in Trauma‐Informed Strategies

Human trafficking is a critical social issue characterized by chronic trauma among victims, and frequently preceded by traumatic experiences that contribute to risk of victimization. Therefore, the research‐based practice of trauma‐informed care is a highly appropriate lens for both prevention and intervention. This work examines federal legislation in the United States related to human trafficking for references to trauma, as well as how the use of research could implicitly direct public policy responses toward trauma‐informed approaches. Legislation on human trafficking has risen substantially since 1989, and the use of research and trauma language within these policies has also observed substantial increases. While the use of trauma language was associated with limited progression in the policy process, legislation using research language was more likely to pass out of Committee and become enacted. Moreover, legislation may leverage research in ways that have the potential to bolster trauma‐informed practice among human trafficking victims. Specifically, research can be used to describe the problem and causal mechanisms (e.g., impact of trauma), guide “best practice” for service delivery, and generate knowledge through studies and evaluations that guide future policy. Therefore, human trafficking legislation that implicitly guides trauma‐informed practice via the use of research may be particularly promising for the field.

Incremental Validity of Coping-oriented Marijuana Use Motives in the Prediction of Affect-based Psychological Vulnerability

The present investigation examined whether coping-oriented motives to use marijuana, as measured by the Marijuana Motives Measure (MMM; Simons et al. in J. Couns. Psychol. 45:265–273, 1998), were uniquely related to affect-based psychological vulnerability factors among marijuana users. Participants were 131 adult current marijuana users (72 women, M _age = 20.14, SD = 3.37 years). As hypothesized, after controlling for gender, cigarettes smoked per day, past 30-day marijuana use, total years of marijuana use, and alcohol consumption, coping motives were significantly and incrementally related to negative affect-based psychological vulnerability factors. No other marijuana use motives demonstrated a similar type of relationship to the dependent variables, providing a high degree of explanatory specificity. These data suggest that coping-oriented motives to use marijuana may be an important explanatory construct in better understanding marijuana and psychological vulnerability relations.     

Impact of a comprehensive safety program on bicycle helmet use among middle-school children

A bicycle helmet program was evaluated in three middle schools using a multiple baseline across schools design. Two of the three schools had histories of enforcement of helmet use. During baseline many students riding their bikes to and from school did not wear their helmets or wore them incorrectly. A program that consisted of peer data collection of correct helmet use, education on how to wear a bicycle helmet correctly, peer goal setting, public posting of the percentage of correct helmet use, and shared reinforcers, all of which were implemented by the school resource officer, increased afternoon helmet use and afternoon correct helmet use in all three schools. Probe data collected a distance from all three schools indicated that students did not remove their helmets once they were no longer in close proximity to the school, and probe data collected in the morning at two of the schools showed that the behavior change transferred to the morning.
