An evaluation of response cost in the treatment of inappropriate vocalizations maintained by automatic reinforcement 总被引:1,自引:0,他引:1

In the current study, we examined the utility of a procedure consisting of noncontingent reinforcement with and without response cost in the treatment of inappropriate vocalizations maintained by automatic reinforcement. Results are discussed in terms of examining the variables that contribute to the effectiveness of response cost as treatment for problem behavior maintained by automatic reinforcement. 相似文献

This study uses an interpretive interview method to examine the micro-processes of generational continuity and change among a group of social activists. Boszormenyi-Nagy's theory of responsibility between generations, alternative models outside the family, and choice are used to explain the instances of change. Implications for research and practice are addressed. 相似文献

This paper describes the process in which families participate in a wilderness experience. Metaphors such as climbing or paddling a canoe are translated into daily living patterns to deepen individual and family self-knowledge, self-esteem, and intimacy. 相似文献

This prospective cohort study used administrative data from the Army Study to Assess Risk and Resilience in Servicemembers to examine associations between neurocognitive functioning and subsequent suicidal events among Regular Army enlisted soldiers during the years 2004–2009. Cases were all soldiers who completed the Army's Automated Neuropsychological Assessment Metrics (ANAM) computerized testing battery prior to documented suicide attempt (n = 607), ideation (n = 955), or death (n = 57). Controls were an equal‐probability sample of 9,893 person‐months from other soldiers. Exploratory factor analysis of five ANAM tests identified a general neurocognitive factor that excluded the mathematic processing test (MTH). When examined separately in logistic regression analyses that controlled for sociodemographics and prior mental health diagnosis, both the general neurocognitive factor (logit [β] = ?.197 to ?.521; p < .01) and MTH (β = ?.024 to ?.064; p < .05) were associated with all outcomes. When both predictors were examined simultaneously, the general neurocognitive factor continued to be associated with all outcomes (β = ?.164 to ?.417; p < .05) and MTH continued to be associated with suicide attempt (β = ?.015; p = .046) and ideation (β = ?.014; p = .018). These small but robust associations suggest that future research must continue to examine the extent to which objective neurocognitive tests may enhance understanding and prediction of suicide risk. 相似文献

Mary Gentile’s Giving Voice to Values presents an approach to ethics training based on the idea that most people would like to provide input in times of ethical conflict using their own values. She maintains that people recognize the lapses in organizational ethical judgment and behavior, but they do not have the courage to step up and voice their values to prevent the misconduct. Gentile has developed a successful initiative and following based on encouraging students and employees to learn how to engage in communication or action to express their values within an organization’s formal and informal value system. The purpose of this analysis is to examine the Giving Voice to Values approach to empowering the individual to take action to deal with lapses in organizational ethics. We examine the role of Giving Voice to Values in business ethics education, considerations for implementing GVV, and recommendations for business educators and corporate ethics officers. We conclude that while GVV is an effective tool, it is not a comprehensive or holistic approach to ethics education and organizational ethics programs. 相似文献
