The curricular approach aligns the mission, goals, outcomes, and practices of a student affairs division, unit, or other unit that works to educate students beyond the classroom with those of the ...institution, and organizes intentional and developmentally sequenced strategies to facilitate student learning. In this book, the authors explain how to implement a curricular approach for educating students beyond the classroom. The book is based on more than a decade of implementing curricular approaches on multiple campuses, contributing to the scholarship on the curricular approach, and helping many campuses design, implement, and assess their student learning efforts. The curricular approach is rooted in scholarship and the connections between what we know about learning, assessment, pedagogy, and student success. For many who have been socialized in a more traditional programming approach, it may feel revolutionary. Yet, it is also obvious because it is straightforward and simple.
This paper reviews the economic research on obesity, covering topics such as the measurement of, and trends in, obesity, the economic causes of obesity (e.g. the monetary price and time cost of food, ...food assistance programs, income, education, macroeconomic conditions, and peer effects), and the economic consequences of obesity (e.g. lower wages, a lower probability of employment, and higher medical care costs). It also examines the extent to which obesity imposes negative externalities, and economic interventions that could potentially internalize such externalities, such as food taxes, subsidies for school-based physical activity programs, and financial rewards for weight loss. It discusses other economic rationales for government intervention with respect to obesity, such as imperfect information, time inconsistent preferences, and irrational behavior. It concludes by proposing a research agenda for the field.
Overall, the evidence suggests that there is no single dominant economic cause of obesity; a wide variety of factors may contribute a modest amount to the risk. There is consistent evidence regarding the economic consequences of obesity, which are lower wages and higher medical care costs that impose negative externalities through health insurance. Studies of economic approaches to preventing obesity, such as menu labeling, taxes on energy-dense foods, and financial rewards for weight loss find only modest effects on weight and thus a range of policies may be necessary to have a substantial effect on the prevalence of obesity.
This book presents an integrated collection of representative approaches for scaling up machine learning and data mining methods on parallel and distributed computing platforms. Demand for ...parallelizing learning algorithms is highly task-specific: in some settings it is driven by the enormous dataset sizes, in others by model complexity or by real-time performance requirements. Making task-appropriate algorithm and platform choices for large-scale machine learning requires understanding the benefits, trade-offs and constraints of the available options. Solutions presented in the book cover a range of parallelization platforms from FPGAs and GPUs to multi-core systems and commodity clusters, concurrent programming frameworks including CUDA, MPI, MapReduce and DryadLINQ, and learning settings (supervised, unsupervised, semi-supervised and online learning). Extensive coverage of parallelization of boosted trees, SVMs, spectral clustering, belief propagation and other popular learning algorithms and deep dives into several applications make the book equally useful for researchers, students and practitioners.
Aims
To estimate the effects of needle and syringe programmes (NSP) and opioid substitution therapy (OST), alone or in combination, for preventing acquisition of hepatitis C virus (HCV) in people who ...inject drugs (PWID).
Methods
Systematic review and meta‐analysis. Bibliographic databases were searched for studies measuring concurrent exposure to current OST (within the last 6 months) and/or NSP and HCV incidence among PWID. High NSP coverage was defined as regular NSP attendance or ≥ 100% coverage (receiving sufficient or greater number of needles and syringes per reported injecting frequency). Studies were assessed using the Cochrane risk of bias in non‐randomized studies tool. Random‐effects models were used in meta‐analysis.
Results
We identified 28 studies (n = 6279) in North America (13), United Kingdom (five), Europe (four), Australia (five) and China (one). Studies were at moderate (two), serious (17) critical (seven) and non‐assessable risk of bias (two). Current OST is associated with 50% risk ratio (RR) =0.50, 95% confidence interval (CI) = 0.40–0.63 reduction in HCV acquisition risk, consistent across region and with low heterogeneity (I2 = 0, P = 0.889). Weaker evidence was found for high NSP coverage (RR = 0.79, 95% CI = 0.39–1.61) with high heterogeneity (I2 = 77%, P = 0.002). After stratifying by region, high NSP coverage in Europe was associated with a 56% reduction in HCV acquisition risk (RR = 0.44, 95% CI = 0.24–0.80) with low heterogeneity (I2 = 12.3%, P = 0.337), but not in North America (RR = 1.58, I2 = 89.5%, P = < 0.001). Combined OST/NSP is associated with a 74% reduction in HCV acquisition risk (RR = 0.26, 95% CI = 0.07–0.89, I2 = 80% P = 0.007). According to Grades of Recommendation Assessment, Development and Evaluation (GRADE) criteria, the evidence on OST and combined OST/NSP is low quality, while NSP is very low.
Conclusions
Opioid substitution therapy reduces risk of hepatitis C acquisition and is strengthened in combination with needle and syringe programmes (NSP). There is weaker evidence for the impact of needle syringe programmes alone, although stronger evidence that high coverage is associated with reduced risk in Europe.
This book introduces readers to process-based understandings of leadership, providing language and tools for engaging in the leadership process for all involved. This practical book was designed for ...college student leaders and educators or professionals who work with student leaders on college campuses. However, it is also accessible for high school students and graduate students to reflect on their identity, capacity, and efficacy as leaders. Based on their experiences as leadership educators, the authors offer grounding concepts of leadership and examples illustrating the complexity of culturally relevant leadership learning.Identity (who you are), capacity (your ability), and efficacy (what you do) are important for students to explore leadership development. These three concepts are core to this book, filling a gap in college student development literature by defining, illustrating, and questioning how they matter to leadership learning.Framing leadership as a journey, this resource offers key learning opportunities for students to engage with others through a range of contexts. Each chapter is organized with various features, engaging readers to get the most out of this book. Features include "call-in boxes" to prepare for learning and "pause for considerations" to apply to personal experiences. Chapters conclude with personal reflection questions, discussion questions, and activities to take leadership learning further. The features are designed to be accessible for utilization in classes, organizations, community work, groups, and individual reflection opportunities.

Laboratory experiences as a part of most U.S. high school science curricula have been taken for granted for decades, but they have rarely been carefully examined. What do they contribute to science ...learning? What can they contribute to science learning? What is the current status of labs in our nation s high schools as a context for learning science? This book looks at a range of questions about how laboratory experiences fit into U.S. high schools: (1) What is effective laboratory teaching?; (2) What does research tell us about learning in high school science labs?; (3) How should student learning in laboratory experiences be assessed?; (4) Do all student have access to laboratory experiences?; (5) What changes need to be made to improve laboratory experiences for high school students?; and (6) How can school organization contribute to effective laboratory teaching? With increased attention to the U.S. education system and student outcomes, no part of the high school curriculum should escape scrutiny. This timely book investigates factors that influence a high school laboratory experience, looking closely at what currently takes place and what the goals of those experiences are and should be. Science educators, school administrators, policy makers, and parents will all benefit from a better understanding of the need for laboratory experiences to be an integral part of the science curriculum and how that can be accomplished.
Increasingly attention has been focused to the degree to which social programs have effectively and efficiently delivered services. Using the differential program evaluation model by Tripodi, Fellin, ...and Epstein (1978) and by Bielawski and Epstein (1984), this paper described the application of this model to evaluating a multidisciplinary clinical consultation practice in child protection. This paper discussed the uses of the model by demonstrating them through the four stages of program initiation, contact, implementation, and stabilization. This organizational case study made a contribution to the model by introducing essential and interrelated elements of a “practical evaluation” methodology in evaluating social programs, such as a participatory evaluation approach; learning, empowerment and sustainability; and a flexible individualized approach to evaluation. The study results demonstrated that by applying the program development model, child-protective administrators and practitioners were able to evaluate the existing practices and recognize areas for program improvement.
