This study provides an in-depth analysis of American mass public shooting conclusions between 1966 and 2017. Specifically, this work examines differences in factors contributing to the perpetrator's likelihood of surviving, being killed, and committing suicide. Ten hypotheses, rooted in previous homicide, suicide, homicide-suicide, and mass public shooting literature consider different psychological, situational, and background factors shaping the outcome of mass public shootings. Significant findings indicate factors influencing perpetrators' suicide include suicidal ideation, higher victim counts, and suicide copycat effects. Factors influencing perpetrators being killed similarly include higher victim counts, the arrival of law enforcement, lethal/non-lethal resistance, and government targets. This investigation provides practical implications for practitioners and policymakers, especially law enforcement and mental health practitioners, seeking to develop intervention and prevention strategies for addressing suicidal ideation and its most lethal outcome: mass public shootings.  相似文献

In Pavlovian fear conditioning, a conditional stimulus (CS, usually a tone) is paired with an aversive unconditional stimulus (US, usually a foot shock) in a novel context. After even a single pairing, the animal comes to exhibit a long-lasting fear to the CS and the conditioning context, which can be measured as freezing, an adaptive defense reaction in mice. Both context and tone conditioning depend on the integrity of the amygdala, and context conditioning further depends on the hippocampus. The reliability and efficiency of the fear conditioning assay makes it an excellent candidate for the screening of learning and memory deficits in mutant mice. One obstacle is that freezing in mice has been accurately quantified only by human observers, using a tedious method that can be subject to bias. In the present study we generated a simple, high-speed, and highly accurate algorithm that scores freezing of four mice simultaneously using NIH Image on an ordinary Macintosh computer. The algorithm yielded a high correlation and excellent linear fit between computer and human scores across a broad range of conditions. This included the ability to score low pretraining baseline scores and accurately mimic the effects of two independent variables (shock intensity and test modality) on fear. Because we used a computer and digital video, we were able to acquire a secondary index of fear, activity suppression, as well as baseline activity scores. Moreover, we measured the unconditional response to shock. These additional measures can enhance the sensitivity of the assay to detect interesting memory phenotypes and control for possible confounds. Thus, this computer-assisted system for measuring behavior during fear conditioning allows for the standardized and carefully controlled assessment of multiple aspects of the fear conditioning experience.  相似文献

The integration of theories and techniques is part of family therapists' daily practice, raising the need to understand which resources are used in this professional's clinical actions. Our aim is to reflect on the use of theoretical and technical resources by family therapists in their daily practice. We developed an inquiry process inspired by collaborative action research and social constructionism. Couple and family therapy sessions were conducted by two family therapists, and we developed subsequent dialogs with them focused on describing theoretical and technical inspirations for their actions. Next, we named four categories of actions in this process: exploratory actions, actions for the construction of relational visions, actions for the construction of communication, and actions for family orientation. The therapists-participants referred to many theoretical and technical resources that inspired their practice. For them, the choice of using one or another resource was based on the demands of the interactive moment, which involves their relational and embodied responses to what was experienced in the sessions. We argue that epistemological coherence is not something that guides the therapist's practice a priori, but something that can be achieved by talking about and reflecting on their actions. This article can contribute to clinical practice and training in family therapy by presenting an interesting reflexive process that can be useful to enhance practice in couple and family therapy (FAPESP, Process n. 2015/21316–1).  相似文献

The current study compared offender and offense characteristics of pretrial defendants found incompetent to stand trial (IST) against those described as general offenders by victims in the 2008 Bureau of Justice Statistics (BJS) survey and evaluated factors that differentiated IST defendants who allegedly used weapons from those who did not during the course of a violent offense. IST defendants were older and used “weapons” more frequently than those reported in the BJS survey; however, other characteristics, including use of firearms, did not differ. No demographic, clinical, or legal factors differentiated pretrial defendants who used weapons from those who did not. Overall, pretrial defendants were frequently diagnosed with a comorbid substance use disorder, and were homeless, unemployed, and had an extensive history of psychiatric hospitalizations and prior arrests at the time of their alleged offenses. Such results indicate that models for comprehensive discharge planning may have utility in addressing the unique needs of this subgroup of mentally disordered offenders. The findings also raise questions about the federal and state prohibition of gun rights to all IST defendants. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Even though there is a general presence of aesthetics in school curricula in most of western countries, both at the level of terminology and at the level of choice and definition of contents, objectives and skills to be developed, the approach to sports and physical education potential for the development of aesthetic education of students still does not seem to be a reality in the agenda of this subject. Moreover, it is not transversal in terms of its different didactic contents. In order to explore its relevance, the aim of this work was to deepen how aesthetics is internal and central to sports experience, and which elements of sports and physical education lived experiences can be relevant in the promotion and development of the aesthetic sensibility of students. We propose the deepening of the subject through an hermeneutical qualitative research approach, confronting the content collected in 19 semi-structured interviews that enabled the thematic analysis of its content, and through it, the discussion of viewpoints of representative subjects among those that are the main players in the consideration of an aesthetic education through sport, namely physical education teachers and researchers in the context of aesthetics and sports sciences. With the information gathered and after its processing, we could conclude that there are aesthetic elements of sport's experience that should be taken into account in an aesthetic educational point of view of physical education, namely: complexity, diversity, playability, tension between drama and accuracy, overcoming experience, risk and vulnerability, unpredictable storylines and uncertainty, technique and effectiveness.  相似文献

This article aims to explore the relationship between clients' narrative transformation and the promotion of vocational decidedness and career maturity in a mid-adolescent case of Life Design Counseling (LDC). To assess LDC outcomes the Vocational Certainty Scale and the Career Maturity Inventory — Form C were used before and after the intervention. To intensively analyze the process of LDC change two measures of narrative change were used: the Innovative Moments Coding System (IMCS), as a measure of innovation emergence, and the Return to the Problem Coding System (RPCS), as a measure of ambivalence towards change. The results show that the three LDC sessions produced a significant change in vocational certainty but not in career maturity. Findings confirm that the process of change, according to the IMCS, is similar to the one observed in previous studies with adults. Implications for future research and practice are discussed.  相似文献

For a long time, the creativity literature has stressed the role of divergent thinking in creative endeavor. More recently, it has been recognized that convergent thinking also has a role in creativity, and the design literature, which sees design as a creative activity a priori, has largely adopted this view: Divergent and convergent thinking are seen as occurring in cyclic phases within the design process. Neurological evidence suggests that frequent shifts between defocused and focused attention to stimuli in memory activation, which equate divergent and convergent thinking, are a hallmark of creative thinking. In this article, we use linkography to show that the shifts between divergent thinking—forelinking of design moves, and convergent thinking—backlinking of moves, are so frequent that at the cognitive scale they can be seen as occurring concurrently in the ideation phase of creative designing. It is proposed that in assessments of creative potential, shifts between divergent and convergent thinking should be the yardstick instead of, or alongside measurements of divergent thinking.  相似文献

Research is presented on the attributional gender bias: the tendency to generate different attributions (explanations) for female versus male students’ performance in math. Whereas boys’ successes in math are attributed to ability, girls’ successes are attributed to effort; conversely, boys’ failures in math are attributed to a lack of effort and girls’ failures to a lack of ability. This bias has been shown in previous research to be committed by teachers, parents, and students themselves. The present work sought to investigate whether this bias among secondary school math teachers might be reduced over time through adoption of an incremental theory of intelligence. Findings revealed at baseline, teachers committed the expected bias in reference to their high-achieving students’ math performance. Following exposure to stimuli, teachers in both experimental and control conditions reduced this bias. Unexpectedly, teachers across conditions showed a type of compensation for the bias by reversing stereotypical attributions for girls’ and boys’ successes and failures in math. Further, participants relapsed to the original bias nearly a year later. Findings indicate the potential to modify attributional gender bias, but also the challenges for achieving long-term changes within school contexts and for emphasizing effort beyond ability in math performance.  相似文献
