Sex offending is a considerable public health and criminal justice system concern. While the research is fairly mixed at best with most pointing toward a general lack of an appreciable deterrent benefit for these polices, no prior evaluation has made a rigorous attempt to determine and define the vast array of implementation costs and public safety benefits of these policies, specifically the Sex Offender and Registration and Notification Act (SORNA). As such, our proposed research strategy involves the development and application of an innovative Cost-Benefit Analysis (CBA) tool. The results from this innovative and dynamic CBA tool with hypothetical data suggests that the 10-year financial benefit for SORNA ranges from $1.01 to $3.91 for every dollar spent when considering the reduction in sex crime specifically, and any crime more generally. This tool holds promise as a mechanism for generating jurisdiction/site-specific cost-benefit analyses. Policy implications are also discussed.  相似文献

Many children struggle to learn to read, and these difficulties can persist well into adulthood. To address this problem, researchers have investigated the processes that underlie reading. An informative body of work has thus identified basic skills (e.g., decoding, vocabulary knowledge) as necessary for successful reading. Researchers also have begun to examine comprehension skills and their contributions to the reading process. In this article we describe research from the cognitive sciences on the processes that underlie higher-order, coherence-oriented comprehension to provide an empirically and theoretically driven perspective for investigating struggling readers' difficulties. We show that this perspective is particularly beneficial in the development and assessment of instructional approaches by relating it to existing, effective interventions. Finally, we demonstrate how our own research activities have derived from this perspective and how preliminary findings extend our understanding of readers' difficulties. This work seeks to address existing challenges in the field of reading comprehension while also suggesting new ways of investigating the plight of struggling readers.  相似文献

Recent feminist philosophers of science have argued that feminist values can contribute to rational decisions about which scientific theories to accept. On this view, increasing the number of feminist scientists is important for ensuring rational and objective theory acceptance. The Underdetermination Thesis has played a key role in arguments for this view [Anderson (1995) Hypatia 10(3), 50–84; Hankinson Nelson (1990) Who knows? From Quine to a feminist empiricism. Temple University Press, Philadelphia; Longino (1990) Science as social knowledge. Princeton University Press, Princeton; Longino (2002) The fate of knowledge. Princeton University Press, Princeton; Kourany (2003) Philosophy of Science 70, 1–14]. This thesis is alleged to open an argumentative “gap” between evidence and theory acceptance and provide a rationale for filling the gap with feminist values. While I agree with the conclusion that feminist values can contribute to rational decisions about which theories to accept, I argue that the Underdetermination Thesis cannot support this claim. First, using earlier arguments [Laudan (1990) in: R. Giere (ed) Minnesota studies in the philosophy of science, vol 14, pp 267–297; Slezak (1991) International Studies in Philosophy of Science 5, 241–256; Pinnick (1994) Philosophy of Science 61, 664–657] I show that Underdetermination cannot, by itself, establish that feminist values should fill the gap in theory acceptance. Secondly, I argue that the very use of the Underdetermination Thesis concedes that feminist values are extra-scientific, a-rational, factors in theory acceptance. This concession denies feminists grounds to explain why their values contribute to rational scientific reasoning. Finally, I propose two alternative ways to explain how feminist values can contribute to rational theory acceptance that do not rely on Underdetermination.

This multiple case study investigated 143 teachers’ responses to focus group questions about their experiences with the simultaneous implementation of three disruptive innovations as part of the U.S. Race-to-the-Top (RTTT) agenda: the Common Core Learning Standards, data-driven instruction, and annual professional performance reviews. We asked: How do teachers describe their experiences implementing these three RTTT innovations? How do teachers describe supports for their adaptation to these innovations? And, for each of these questions, and since the study purposefully included schools with above-predicted student outcomes (i.e. odds-beaters) as well as a comparison set of typically performing schools, we inquired: In what ways do odds-beating school teachers’ experiences differ from their peers in typically performing schools? Guided by an emergent framework that emphasizes the relationships among teacher agency, engagement, efficacy, and emotional resilience and how these vary in different school contexts, findings suggest that district office innovation leadership and resource allocations, school leadership structures and strategies, and collaborative teams and communities of practice vary and relate to teachers’ experiences of innovation implementation. This study advances an empirically-grounded and theoretically rich framework for investigation of teachers’ performance adaptation during policy innovation implementation and suggests implications for future research, policy, and practice.  相似文献

This study used a person-centered approach to identify naturally occurring combinations of intrinsic motivation and controlled forms of extrinsic motivation (i.e., introjected and external regulation) and their correlates in an academic context. 1061 high school students completed measures of academic motivation, performance, and school-related correlates. Cluster analysis revealed four motivational profiles characterized by comparably high levels of all types of motivation (high quantity), high intrinsic motivation relative to introjected and external regulation (good quality), low intrinsic motivation and introjected regulation relative to external regulation (poor quality), and very low intrinsic motivation and introjected regulation relative to external regulation (low quantity with poor quality). Students in the high quantity and good quality profiles reported the strongest academic performance and greatest overall extracurricular participation, with students in different motivational profiles likely to participate in different types of activities. Students in the high quantity profile, moreover, perceived the most teacher support and school relatedness. These findings suggest that controlled forms of extrinsic motivation may not be associated with maladaptive outcomes at the high school level when coupled with high levels of intrinsic motivation.  相似文献

The purpose of this study was to examine how different scoring procedures affect interpretation of maze curriculum‐based measurements. Fall and spring data were collected from 199 students receiving supplemental reading instruction. Maze probes were scored first by counting all correct maze choices, followed by four scoring variations designed to reduce the effect of random guessing. Pearson's r correlation coefficients were calculated among scoring procedures and between maze scores and a standardized measure of reading. In addition, t tests were conducted to compare fall to spring growth for each scoring procedure. Results indicated that scores derived from the different procedures are highly correlated, demonstrate criterion‐related validity, and show fall‐to‐spring growth. Educators working with struggling readers may use any of the five scoring procedures to obtain technically sound scores.  相似文献

The purpose of this study was to examine the development of oral reading fluency in a sample of first-grade children. Using growth curve analysis, models of growth were identified for a combined sample of at-risk (AR) and not-at-risk (NAR) children, and predictors of growth were identified for the longitudinal AR sample in first and second grade. Large and serious differences in reading fluency growth between the AR and NAR samples were apparent early, replicating other reports. Theories of sight-word learning and reading fluency were supported, in that letter-sound fluency was a uniquely significant predictor of first-grade reading fluency. The effects of phonological awareness and rapid automatized naming were mediated by the other variables in the model. Growth in first-grade oral reading fluency accounted for the most unique variance in second-grade growth and end-of-year performance. The results suggest that word reading fluency should be regarded as developing concomitantly with early word recognition rather than as a later-developing skill.  相似文献
