Most criminal justice programs began as extensions of vocational technical training courses, but within the last decade they have begun to parallel the liberal arts programs originally proposed. As a result of this reorientation, criminal justice instructors lack many of the instructional methods used by colleagues in other fields. In addition, the dual nature of criminal justice instruction, requiring both experience and theory, places demands on criminal justice instructors that their colleagues may not experience. The field needs an instructional approach that blends the best of the vocational aspects and the theoretical underpinnings. This paper reviews cognitive learning theory, specifically Kolb's experiential learning model. Recommendations are offered for the application of this model to instruction in criminal justice courses. 相似文献

To date, assessment validity research on non-native English speaking students in the United States has focused exclusively on those who are presently English language learners (ELLs). However, little, if any, research has been conducted on two other sizable groups of language minority students: (a) bilingual or multilingual students who were already English proficient when they entered the school system (IFEPs), and (b) former English language learners, those students who were once classified as ELLs but are now reclassified as being English proficient (RFEPs). This study investigated the validity of several standards-based assessments in mathematics and science for these two student groups and found a very high degree of score comparability, when compared with native English speakers, for the IFEPs, whereas a moderate to high degree of score comparability was observed for the RFEPs. Thus, test scores for these two groups on the assessments we studied appear to be valid indicators of their content knowledge, to a degree similar to that of native English speakers. 相似文献

This was the first of a series of papers presented February 20, 2001 at a national conference sponsored by North Texas State University held in the Omni Hotel Dallas, TX. The author relates the 1950 status of two-year college development, numbers and locations of university professors specializing in the field, and the need to persuade citizens they should have a public two-year college in their midst. Events are traced which led up to the overwhelming demand by the public in the late 1960s and early 1970s to have their own two-year college. This condition precipitated the untiring work of university faculty specialized in this field to accommodate the need for assistance at both the state level planning and for local college establishment. The citizens participatory comprehensive study involvement developed initially as a way of overcoming resistance and persuading citizens they needed a college is a viable approach today for periodically evaluating and future planning to meet changing societal manpower needs. The author urges continued use of action research tools to accommodate evolving local area educational needs. 相似文献

Background:Little is known about exercise cardiac power(ECP),defined as the ratio of directly measured maximal oxygen uptake with peak systolic blood pressure during exercise,on heart failure(HF)risk.We examined the association of ECP and the risk of HF.Methods:This was a population-based cohort study of 2351 men from eastern Finland.The average time to follow-up was 25 years.Participants participated at baseline in an exercise stress test.A total of 313 cases of HF occurred.Results:Men with low ECP(<9.84 mL/mmHg,the lowest quartile)had a 2.37-fold(95%confidence interval(95%CI):1.68-3.35,p<0.0001)hazards ratio of HF as compared with men with high ECP(>13.92 mL/mmHg,the highest quartile),after adjusting for age.Low ECP was associated with a 1.96-fold risk(95%CI:1.38-2.78,p<0.001)of HF after additional adjustment for conventional risk factors.After further adjustment for left ventricular hypertrophy,the results hardly changed(hazards ratio=1.87,95%CI:1.31-2.66,p<0.001).One SD increase in ECP(3.16 mL/mmHg)was associated with a decreased risk of HF by 28%(95%CI:17%-37%).Conclusion:ECP provides a noninvasive and easily available measure from cardiopulmonary exercise tests in predicting HF.However,ECP did not provide additional value over maximal oxygen uptake. 相似文献

Majority opinions are often observed in the process of social interaction in online communities, but few studies have addressed this issue with empirical data. To identify an appropriate theoretical lens for explaining majority opinions in online environments, this study investigates the skewness statistic, which indicates how many “Likes” are skewed to major comments on a Facebook post; 3489 posts are gathered from the New York Times Facebook page for 100 days. Results show that time is not an influential factor for skewness increase, but the number of comments has a logarithmic relation to skewness increase. Regression models and Chow tests show that this relationship differs depending on topic contents, but majority opinions are significant in overall. These results suggest that the bandwagon effect due to social affordance can be a suitable mechanism for explaining majority opinion formation in an online environment and that majority opinions in online communities can be misperceived due to overestimation. 相似文献

ABSTRACTThe aim of this study was to assess if tactical and technical performance indicators (PIs) could be used in combination to model match outcomes in Australian Football (AF). A database of 101 technical PIs and 14 tactical PIs from every match in the 2009–2016 Australian Football League (AFL) seasons was merged. Two outcome measures Win-loss and Score margin were used as dependent variables. The top 45 ranked technical and tactical PIs from a feature selection process were used to model match outcome using decision tree and Generalised Linear Models (GLMs). Of the top 45 selected features, this included seven tactical PIs. The Win-loss-based Decision tree model achieved a classification accuracy of 89.0% and GLM 93.2%. A Score margin-based GLM achieved a root mean squared error (RMSE) of 6.9 points. A combined approach to the classification of match outcomes provided no improvement in model accuracy compared with previous literature. However, this study has established the relative importance of technical and tactical measures of performance in relation to successful team performance in AF. 相似文献

INTRODUCTION Scalable video coding (SVC) (Schwarz et al., 2004) is the most promising video format for appli- cations of collaborative communication. First, SVC format, which is extended from the latest advanced video coding (AVC), is appropriate for creating a wide variety of bitrates with high compression effi- ciency. Second, an original SVC bitstream can be easily truncated in different ways to meet various characteristics and variations of devices and connec- tions. The scalabil… 相似文献

Outer space is a topic that is relevant to our future, promotes a universal sense of wonder and reinforces the idea that we all share one planet. Early childhood teachers, parents, grandparents and children all find the subject of outer space exploration fascinating. Space exploration weaves together all aspects of our experience and generates an enthusiasm to learn more. Space adventure also creates a new hero system for our children. Achievements and success are based on knowledge, skill and dedication to a common cause: the betterment of life for all people. 相似文献
