Police killings of unarmed Black males is an all too often occurrence. Just how many have succumbed in this manner is unknown due to a lack of a comprehensive reporting method. However, an undeniable fact and reality is that the Black community, and society as a whole, suffers as a result of the loss of these individuals. The authors of this article suggest that police shootings of unarmed Black males may never cease. The authors propose simple but thoughtful ways in which Black males should be educated by the Black community (family, church, and other institutions) regarding general survival skills and more specifically survival skills in regards to police encounters. Implications for further research are also presented.  相似文献

We describe SwarmSight (available at https://github.com/justasb/SwarmSight), a novel, open-source, Microsoft Windows software tool for quantitative assessment of the temporal progression of animal group activity levels from recorded videos. The tool utilizes a background subtraction machine vision algorithm and provides an activity metric that can be used to quantitatively assess and compare animal group behavior. Here we demonstrate the tool’s utility by analyzing defensive bee behavior as modulated by alarm pheromones, wild-bird feeding onset and interruption, and cockroach nest-finding activity. Although more sophisticated, commercial software packages are available, SwarmSight provides a low-cost, open-source, and easy-to-use alternative that is suitable for a wide range of users, including minimally trained research technicians and behavioral science undergraduate students in classroom laboratory settings.  相似文献

Although students with emotional disturbance are commonly known for their social behavior deficits, they often have academic deficits as well. Unfortunately, most of the intervention research and many of the practices used with this population focus upon their social behavior deficits and fail to recognize the need to improve their academic skills. Therefore, there is a need for identifying research-based interventions that focus on ameliorating social and academic deficits often exhibited by students with emotional disturbance. The purpose of this study was to examine the differential effects of self-monitoring of attention versus self-monitoring of performance on the academic and social behaviors of three minority students identified as having emotional disturbance while independently engaged in practicing mathematical calculations. The findings suggest that students with emotional disturbance may perform better socially and academically during math practice while self-monitoring their academic performance. Social validity data also suggest that students rated self-monitoring of academic performance more favorably than self-monitoring of attention. In addition, all target students in this study exhibited levels of on-task behavior more similar to their peers while self-monitoring academic performance compared to self-monitoring attentive behavior.  相似文献

Theories of semantic memory differ in the extent to which relationships among concepts are captured via associative or via semantic relatedness. We examined the contributions of these two factors, using a visual world paradigm in which participants selected the named object from a four-picture display. We controlled for semantic relatedness while manipulating associative strength by using the visual world paradigm’s analogue to presenting asymmetrically associated pairs in either their forward or backward associative direction (e.g., ham—eggs vs. eggs—ham). Semantically related objects were preferentially fixated regardless of the direction of presentation (and the effect size was unchanged by presentation direction). However, when pairs were associated but not semantically related (e.g., iceberg—lettuce), associated objects were not preferentially fixated in either direction. These findings lend support to theories in which semantic memory is organized according to semantic relatedness (e.g., distributed models) and suggest that association by itself has little effect on this organization.  相似文献

Using adaptive structuration theory as a framework [DeSanctis, G., & Poole, M. S. (1994). Capturing the complexity in advanced technology use: Adaptive structuration theory. Organization Science, 5(2), 121–147], we examined the influence of organizational context (competitive versus cooperative) and introductory meeting communication medium (face-to-face versus electronic) on the development of trust and collaborative behaviors of dyads communicating electronically. Based on a sample of 208 senior business students operating in computer-mediated (CM) dyads while performing a strategic decision-making simulation, we found that context, introductory communication medium, and time interacted to influence trust and collaborative behaviors. The pattern of development of trust and collaborative behaviors differed for the same introductory communication medium in different context conditions. Further, the level of trust and collaboration for dyad members in the competitive/electronic introductory meeting condition lagged significantly behind those in the other conditions. The findings suggest that introductory face-to-face interaction plays a more important role in facilitating the development of trust and collaboration in a CM environment when the context is competitive.  相似文献

Understanding how the human brain integrates features of perceived events calls for the examination of binding processes within and across different modalities and domains. Recent studies of feature-repetition effects have demonstrated interactions between shape, color, and location in the visual modality and between pitch, loudness, and location in the auditory modality: repeating one feature is beneficial if other features are also repeated, but detrimental if not. These partial-repetition costs suggest that co-occurring features are spontaneously bound into temporary event files. Here, we investigated whether these observations can be extended to features from different sensory modalities, combining visual and auditory features in Experiment 1 and auditory and tactile features in Experiment 2. The same types of interactions, as for unimodal feature combinations, were obtained including interactions between stimulus and response features. However, the size of the interactions varied with the particular combination of features, suggesting that the salience of features and the temporal overlap between feature-code activations plays a mediating role.  相似文献

The present study related generational status, marital status, parental overprotection (control), and cultural value conflict to self-esteem and depression among first and second-generation Asian Indian immigrant women in the south-midwestern United States. Self-report data from 73 community-dwelling women supported the hypotheses that unmarried and second-generation women would report greater maternal control and cultural value conflict than would married and first-generation women. Second-generational status, high maternal control, and high cultural value conflict correlated with higher depressive symptomology; being married, low maternal control, and low cultural value conflict were related to high self-esteem. Regression analyses indicated a mediating role for cultural value conflict for depression symptom predictors, but not for self-esteem predictors. Open-ended response data provided enriched understanding of these women’s cultural and family conflicts.  相似文献

The spread of endemic school violence in the United States from urban black, Hispanic, and other minority areas to white suburbia and smaller communities has alarmed the nation. Contrary to common belief, the incidence of school violence has been fairly stable except in the areas of violence against females and gang membership. The culture of violence and easy availability of guns is a major contributing factor. The relationship between school violence, suicidality and psychiatric disorders, specifically depressive disorders, conduct disorder, and alcohol and drug abuse are discussed within the framework of the psychological autopsy of suicide in children and adolescents. There are striking similarities between acts of school violence and suicidality. Specific guidelines are provided regarding clinical assessment of potentially violent youth with emphasis on exploration of attachment behavior in various developmental stages.  相似文献
