This effort provides a quantitative method that incorporates the objectives of a C4I system. A systematic methodology, which incorporates expert opinion and operational necessities, is provided to evaluate communications networks. While the specific weighting and measures for a value hierarchy will depend upon the operational environment and the decision makers, a framework to develop such a hierarchy is provided. The approach produced graphical displays that provide a great deal of insight into the tradeoffs which could be made and the driving factors behind the system scores.

The 'task confronting contemporary theology', says James Fodor, 'is that of the rehabilitation or recovery of a distinctively Christian vision of truth' ( Christian Hermeneutics [Oxford, 1995] p. 72). In this paper I examine Fodor's attempt to construct a Christian or transformational theory of truth. I argue that his analysis of truth in terms of transformation leads to a concept of truth which is both subjective and relative. I argue further that Fodor's truth theory is either committed to a version of creative anti-realism, according to which the existence of basic structure of the world is determined by our linguistic activities, or it implies that although our language doesn't correspond to the world, we should go on making our theological truth claims anyway. I conclude that Fodor's Christian theory of truth is in most crucial respects not Christian at all.  相似文献

This exploratory study examined the relationship between acculturation and racial identity among African Americans. One hundred eighty‐seven African American students completed the Black Racial Identity Attitude Scale (J. F. Helms & T. A. Parham, 1990) and the African American Acculturation Scale (AAAS; H. Landrine & E. Klonoff, 1995). Acculturation was associated with 3 of the 5 AAAS subscales: Dissonance, Immersion, and Emersion; Immersion had the greatest correlation with acculturation. A simultaneous regression analysis showed that the Pre‐Encounter subscale was a significant predictor of acculturation.  相似文献

The need for cultural competence and the need for evidence-based practice in mental health services are major issues in contemporary discourse, especially in the psychological treatment of people of color. Although these 2 paradigms are complementary in nature, there is little cross-fertilization in the psychological literature. The present article illustrates the complementary nature of these 2 paradigms. A main point of convergence is related to the development of culturally adapted interventions in the move from efficacy research to effectiveness studies. The implications of cultural adaptations of empirically supported treatments for mental health services in terms of research and practice with ethnic/racial minority populations are discussed.  相似文献

The purpose of this treatment effectiveness study was to evaluate the flexible application of a manualized cognitive behavioral treatment (CBT) for PTSD and related symptoms in survivors of the 9/11 terrorist attack on the World Trade Center. Treatment delivery ranged from 12 to 25 sessions; therapist experience ranged from no prior training to extensive training in CBT; and training and supervision of clinicians in the treatment manual was considerably less than that required in a randomized clinical trial (RCT). Paired t-tests demonstrated significant pre-post reductions in symptoms of PTSD and depression for the flexible application of the treatment. A benchmarking analysis revealed that the moderate-to-large effect sizes found for these variables were similar to those obtained in an RCT of the same treatment. Furthermore, effect sizes on measures of outcomes particularly relevant to this population of mass violence survivors such as functional impairment, use of alcohol and drugs to cope, and use of social support to cope, were also medium to large.  相似文献

Memory, suggestibility, stress arousal, and trauma-related psychopathology were examined in 328 3- to 16-year-olds involved in forensic investigations of abuse and neglect. Children's memory and suggestibility were assessed for a medical examination and venipuncture. Being older and scoring higher in cognitive functioning were related to fewer inaccuracies. In addition, cortisol level and trauma symptoms in children who reported more dissociative tendencies were associated with increased memory error, whereas cortisol level and trauma symptoms were not associated with increased error for children who reported fewer dissociative tendencies. Sexual and/or physical abuse predicted greater accuracy. The study contributes important new information to scientific understanding of maltreatment, psychopathology, and eyewitness memory in children.  相似文献

Web-based software was used to deliver and record the effects of programmed instruction that progressively added formal prompts until attempts were successful, programmed instruction with one attempt, and prose tutorials. Error-contingent progressive prompting took significantly longer than programmed instruction and prose. Both forms of programmed instruction substantially increased the appropriate use of behavioral vocabulary during subsequent interpretive essays. These behavioral gains extended to a different setting, suggesting that more was being learned than simply how to answer programmed tutorial frames correctly.  相似文献

The American Academy of Pediatrics (AAP) recommends that infants spend supervised time in the prone (tummy) position to foster motor development and prevent cranial deformities. However, infants may not tolerate the position, and consequently, caregivers may avoid placing their infants in the prone position. The AAP recommends that caregivers provide toys or interaction during tummy time. We evaluated the individual and combined effects of a play mat and experimenter interaction on negative vocalizations and head elevation during tummy time—positive effects were limited. Next, we evaluated a parent-led intervention wherein mothers interacted with their infants, using a toy, while lying chest-to-chest. This intervention was associated with a reduction in negative vocalizations and an increase in head elevation for the majority of infants. Additionally, mothers rated the effectiveness of the parent-led intervention more favorably than the experimenter-led intervention, suggesting the effects of the parent-led intervention were also socially valid.  相似文献

This study examined heterogeneity in parental and community violence exposure during middle school and its association with bullying perpetration and victimization in high school. Youth (N = 1,611) in four Midwestern middle schools participated. Parallel process growth mixture latent transition analysis was used to understand how trajectory profiles of middle school violence exposure was associated with high school bullying profiles. Impulsivity, depression, school belonging, and delinquency were assessed as moderators of the transition probabilities. A three class solution was found for violence exposure: decreasing parental violence/increasing community violence (n = 103; 6.4%), stable high parental violence and low community violence (n = 1,027; 63.7%), and increasing parental violence and stable high community violence (n = 481; 29.8%). Similarly, a three class solution was found for high school bullying: High Bullying Perpetration and High Victimization class (n = 259; 16%), Victimization only (n = 1145; 71%), and low all class (n = 207; 13%). The largest proportion of youth transitioning into the high bullying and high victimization class were from the decreasing parental violence/increasing community violence. Depression, impulsivity, school belonging, and delinquency all had various moderating effects on transition probabilities. Our findings make it apparent that early forms of parental and community violence are associated with aggressive behaviors and experiences with victimization during high school. Prevention and intervention efforts should target individuals who display early and chronic patterns of exposure to violence as these individuals have the greatest risk of later aggressive and victimization in high school.  相似文献

School violence is a significant public health concern that occurs in many forms. Physical aggression can cause serious bodily injury and long-term negative effects, and both teachers and students experience significant rates of physical aggression. There are few studies examining teachers’ experiences of physical aggression. Studies that go beyond prevalence are limited, and we know little about the triggers and consequences that surround these incidents. This qualitative investigation used an antecedent-behavior-consequence (A-B-C) framework to understand how incidents of physical aggression directed toward teachers unfold. The sample included 193 elementary and secondary teachers who completed an anonymous, online survey and described events leading up to and following their experiences with physical aggression. Using conventional content analysis, we identified common antecedents, such as breaking up fights, discipline, and directives, and common consequences, such as student removal, school staff involvement, positive outcomes, and inaction. Further analyses revealed seven common A-B-C patterns among physical aggression incidents that are highlighted and discussed. Utility of the A-B-C framework for teacher-directed violence is described, along with implications for research, practice, and policy. Exploring the context surrounding incidents of physical aggression directed against teachers provides useful information for violence prevention and interventions.  相似文献
