Crime analysts study criminal activity and police function to improve performance. Analysts inform operations, aid resource allocation, and evaluate programs. These tasks require high levels of statistical literacy. Given that most analysts are college-educated civilians, college coursework in statistics and/or crime analysis may represent the foundational knowledgebase within the profession. However, little research has attempted to determine if coursework teaches the skills needed by analysts. Underlying this issue is a limited understanding about what technical skills crime analysts regularly use. Analyzing parallel surveys of 98 criminal justice educators and 146 crime analysts, this study compares the skills taught in undergraduate-level statistics and crime analysis courses to those used by analysts. Comparisons are made between perceptions of the value of coursework. Results indicate discrepancies between the orientation of coursework and the needs of analysts which underscore differences in the perceived relevance of statistics education. Recommendations are discussed.  相似文献

The impact of collaboration on teachers’ individual data use   总被引:1,自引:1,他引:0  
Research considers collaboration to be a significant factor in terms of how teachers use data to improve their practice. Nevertheless, the effects of teacher collaboration with regard to teachers’ individual data use has remained largely underexplored. Moreover, little attention has been paid to the interplay between collaboration and the personal factors that influence teachers’ data use. This paper addresses this research gap by defining factors that affect collaboration, and by investigating the impact of collaboration on teachers’ individual data use. The resulting research questions were answered by drawing on questionnaire data from 1,472 primary and secondary school teachers in Flanders. The findings indicate that collaboration is the main explanatory factor for teachers’ individual data use compared to teachers’ self-efficacy and attitude. Therefore, this study demonstrates the value of collaboration for future research and for creating a supportive environment for teachers’ individual data use.  相似文献

This study examined the development of autobiographical memory specificity (AMS) in a longitudinal randomized controlled trial of 242 maltreated and nonmaltreated children (aged 36–86 months; 50.4% male; 39.7% Black, 25.9% White, 34.5% Latinx/other) and their mothers. Half of the maltreated families were randomized to receive an intervention to improve maternal reminiscing. The effects of maltreatment and the intervention on children’s AMS via two indices of maternal reminiscing, sensitive guidance, and elaboration, were evaluated. Bidirectional associations between AMS and child maladjustment were also examined. Intervention-related improvement in maternal sensitive guidance 6-month postintervention (b* = .36) related to greater AMS among maltreated children 1 year later (b* = .19). These findings underscore the role of maternal sensitive guidance in facilitating AMS.  相似文献

Background: The American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR) recommends health related quality of life (HRQL) measurement with all cardiovascular and pulmonary patients. The current pattern of use of HRQL measurement among cardiovascular and pulmonary physical therapists is unknown. Objective: The purpose of this study was to evaluate the pattern of use of HRQL measurement among cardiovascular and pulmonary physical therapists. Design: The study used a semi-structured interview format within the context of 3 focus groups. Methods: Eleven physical therapists participated in this study and all were members of the Cardiovascular and Pulmonary Section of the American Physical Therapy Association (APTA). Participants participated in a conference call and were provided a question tree to guide discussion. Results: Several primary themes emerged, including decreased knowledge, barriers, and poor indicators of patient status. In addition, several subthemes developed including lack of familiarity, lack of use, administrative and cost limitations, inappropriateness of tool for patient population, correlation between function and quality of life, and suggestions for future outcome measures. Conclusions: A lack of familiarity and use of HRQL measurement and barriers to their use were established. In addition, ideas for future research on HRQL measurements with specific patient populations in physical therapy practice were defined.Key Words: health related quality of life, outcomes measurement  相似文献

Two studies investigated 5- to 10-year-olds’ (N = 194) positivity bias when forecasting the future. Children from two geographic locations (mostly Caucasian, higher income college town; mostly African American, lower income urban community) completed a future expectations task (FET). For multiple scenarios, children predicted whether a positive versus negative (optimism items) or a positive versus extraordinary positive (wishful thinking items) outcome would occur, including its likelihood. In both samples, optimism and wishful thinking decreased with age, optimism was higher than wishful thinking, children did not show a comparative self-optimism bias, and individual differences in the FET optimism score correlated with self-reported dispositional optimism and hope. Exploratory comparisons revealed between-sample equivalence in responses to all measures, except for less tempered wishful thinking in the urban community.  相似文献

Helping has many positive consequences for both helpers and recipients. However, in the present research, we considered a possible downside to receiving help: that it signals a deficiency. We investigated whether young children make inferences about intelligence from observing some groups of people receive help and other groups not. In a novel group paradigm, we show that children (4–6 years) think groups that receive help are less smart (n = 44) but not less nice (n = 45). Children also generalized their inferences about relative intelligence to new group members (n = 55; forced-choice-method). These results have implications for understanding how children develop stereotypes about intelligence as well as for educational practices that group children according to their ability.  相似文献

How do parents think about and react to their children's racial biases? Across three studies (= 519) we investigated whether and how parents’ Internal Motivation to Respond without Prejudice Scale (IMS) predicted standards for their children's race-related behavior, and tested parents’ affective reactions to imagining their children violating their standards. Studies 1 and 2 demonstrated that parents (of 4- to 12-year-old children) with high IMS set more stringent standards for their children's race-related behavior than their low IMS counterparts. Upon considering their children expressing racial bias, high IMS parents reported negative self-directed affect (i.e., guilt; Studies 2 and 3), an affective response that motivates prejudice reduction in adults. The results have implications for involving parents in prejudice interventions targeting children's biases.  相似文献

The primary study objective was to identify determinants of short-term recovery from a 161-km ultramarathon. Participants completed 400 m runs at maximum speed before the race and on days 3 and 5 post-race, provided a post-race blood sample for plasma creatine kinase (CK) concentration, and provided lower body muscle pain and soreness ratings (soreness, 10-point scale) and overall muscular fatigue scores (fatigue, 100-point scale) pre-race and for 7 days post-race. Among 72 race finishers, soreness and fatigue had statistically returned to pre-race levels by 5 days post-race; and 400 m times at days 3 and 5 remained 26% (P = 0.001) and 12% (P = 0.01) slower compared with pre-race, respectively. CK best modelled soreness, fatigue and per cent change in post-race 400 m time. Runners with the highest CKs had 1.5 points higher (P < 0.001) soreness and 11.2 points higher (P = 0.006) fatigue than runners with the lowest CKs. For the model of 400 m time, a significant interaction of time with CK (P < 0.001) indicates that higher CKs were linked with a slower rate of return to pre-race 400 m time. Since post-race CK was the main modifiable determinant of recovery following the ultramarathon, appropriate training appears to be the optimal approach to enhance ultramarathon recovery.  相似文献

This study assessed the extent to which executive functions (EF), according to their factor structure in 5-year-olds (= 244), influenced early quantity–number competencies, arithmetic fluency, and mathematics school achievement throughout first and second grades. A confirmatory factor analysis resulted in updating as a first, and inhibition and shifting as a combined second factor. In the structural equation model, updating significantly affected knowledge of the number word sequence, suggesting a facilitatory effect on basic encoding processes in numerical materials that can be learnt purely by rote. Shifting and inhibition significantly influenced quantity to number word linkages, indicating that these processes promote developing a profound understanding of numbers. These results show the supportive role of specific EF for specific aspects of a numerical foundation.  相似文献
