Incentive-Based Instruments for Water Management

This report provides a synthesis review of a set of incentive-based instruments that have been employed to varying degrees around the world. It is part of an effort by The Rockefeller Foundation to improve understanding of both the potential of these instruments and their limitations. The report is divided into five sections. Section 1 provides an introduction to the synthesis review. Section 2 describes the research methodology. Section 3 provides background on policy instruments and detail on three incentive-based instruments -- water trading, payment for ecosystem services, and water quality trading -- describing the application of each, including their environmental, economic, and social performances, and the conditions needed for their implementation. Section 4 highlights the role of the private sector in implementing these instruments, and Section 5 provides a summary and conclusions

Violence against Canadian Women

<p>Abstract</p> <p>Health Issue</p> <p>Exposure to violence as children or as adults places a woman at higher risk of poor health outcomes, both physical and psychological. Abused women use more health care services and have poorer social functioning than non-abused women. Knowledge of the prevalence of violence against women, and of which women are at risk, should assist in the planning of services for abuse prevention and treatment of the health consequences of abuse.</p> <p>Key Findings</p> <p>The highest rates of any partner violence were in Alberta (25.5%) and British Columbia (23%). The lowest rates were in Ontario (18.8%). Women aged 15–24 had the highest rates in all regions in Canada, compared with older women. Aboriginal women in Manitoba/Saskatchewan and Alberta had higher rates of violence (57.2% and 56.6% respectively) than non-Aboriginal women (20.6%). Lower rates of partner-related violence were reported among women not born in Canada (18.4%) than among Canadian-born women (21.7%). Visible minority women reported lower rates of lifetime sexual assault (5.7%) than non-visible minority women (12.3%). Perceptions of violence may vary by ethnicity.</p> <p>Data Gaps and Recommendations</p> <p>More information is required concerning the prevalence of violence among Aboriginal women, immigrant and refugee women, women with disabilities, lesbian women and pregnant women. Future national population-based surveys need better questions on the health consequences of violence and related resource utilization. Further research is needed to identify the health care system's role in prevention, management and rehabilitation as they relate to violence against women. Future programs and policies must be based on valid, reliable and comprehensive empirical data.</p

State Policy and Classroom Performance: Mathematics Reform in California

In the early 1990\u27s many states tried to devise more robust and coherent instructional policies, in efforts to make teaching and learning more thoughtful and demanding. Policymakers and reformers pressed teachers to help students understand mathematical concepts, to interpret serious literature, to write creatively about their own ideas and experiences, and to converse thoughtfully about history and social science. But these efforts to reform instruction encountered skepticism about the link between policy and pedagogy. Skeptics ask if it is reasonable to expect state policies to steer teaching and learning sharply away from long-established conventional practice, noting that previous efforts to change practice on a large scale had failed. As instructional policy moved to the top of many state education agendas in the late 1990s, interest in the relations between policy and practice has grown. In this issue of CPRE Policy Briefs, we report encouraging findings from an important study that addresses these relationships. We use data from a 1994 survey of California elementary school teachers to probe the classroom effects of state efforts to reform mathematics teaching and learning in California. We report that policy changes did lead both to changed classroom practice and to improved student performance. In this brief, we develop a rudimentary model of the relationship between policy and practice. Student achievement is the ultimate dependent measure; teachers’ reported classroom practice in mathematics is an influence on achievement, but practice also is a measure of the effects of teachers’ learning opportunities about new math curriculum. We present results which show that teachers’ learning opportunities influenced their practice, and that both teachers’ learning opportunities and their practice influenced students’ mathematics achievement. The results suggest that teachers’ practice can change in ways that favorably influence student achievement, and that policy can play an important role in making those changes possible. We begin with a review of the California reform, briefly describe the research approach, and then discuss the major findings

Instructional Policy and Classroom Performance: The Mathematics Reform in California

Educational reformers increasingly seek to manipulate policies regarding assessment, curriculum, and professional development in order to improve instruction. They assume that manipulating these elements of instructional policy will change teachers\u27 practice, which will then improve student performance. We formalize these ideas into a rudimentary model of the relations among instructional policy, teaching, and learning. We propose that successful instructional policies are themselves instructional in nature: because teachers figure as a key connection between policy and practice, their opportunities to learn about and from policy are a crucial influence both on their practice, and, at least indirectly, on student achievement. Using data from a 1994 survey of California elementary school teachers and 1994 student California Learning Assessment System (CLAS) scores, we examine the influence of assessment, curriculum, and professional development on teacher practice and student achievement. Our results bear out the usefulness of the model: under circumstances that we identify, policy can affect practice, and both can affect student performance

A Twisted Dimer Model for Knots

We develop a dimer model for the Alexander polynomial of a knot. This recovers Kauffman\u27s state sum model for the Alexander polynomial using the language of dimers. By providing some additional structure we are able to extend this model to give a state sum formula for the twisted Alexander polynomial of a knot depending on a representation of the knot group

Supporting allied health professionals in their role as practice educators

Aim: To find out what continuing professional development (CPD) and support Allied Health Professions’ practice educators felt would be beneficial to their role to support good learning experiences for students during practice placements. Background: For the first time, representatives from the four universities that run AHP pre-registration education programmes in Scotland, and NHS Education for Scotland (NES) collaborated to design and distribute a questionnaire to student practice educators across all sectors in Scotland. Method: An electronic questionnaire was designed and piloted. It consisted of closed questions using 5-point likert scales and open questions about different aspects of AHP Practice Educator preparation and ongoing CPD and support. The questionnaire was circulated by email three times through university, NES, and professional body networks. Respondents:1127 responses were received from 12 professions. 1082 responses were received from NHS Scotland educators (11% of the regulated AHP workforce), 45 were from AHPs providing practice placements in other sectors. The majority of responses were from experienced Practice Educators. Outcomes: The universities and NES now have a ranked list of CPD needs for practice educators. Key messages from the open questions have been identified about how educators prefer to access CPD and broader support issues both within the practice setting and from universities

THE IDENTIFICATION AND CHARACTERIZATION OF AN INTRINSIC CD39/A2R-BASED REGULATORY MECHANISM THAT GOVERNS MACROPHAGE ACTIVATION RESPONSES

Macrophages are acutely sensitive to changes within their environment and can readily develop into a variety of activation states important for both the progression and resolution of inflammation. In response to immunological threats, macrophages must be able to effectively clear infections without sacrificing the integrity of the affected tissue. Thus, these cells must successfully balance their activation responses in order to preserve tissue function and the overall health of the host. The failure to properly regulate macrophage activation responses often manifests in the clinic in a variety of disease scenarios including sepsis, chronic inflammatory disorders, and cutaneous Leishmaniasis. While many factors that drive the initiation of macrophage activation are known, it remains unclear what governs the transition to an immunosuppressive state. This study reveals that macrophages can control their own activation status through the coordination between the ecto-ATPase, CD39, and the adenosine 2a and 2b receptors (A2Rs). The first part of this work shows that soon after toll-like receptor (TLR) stimulation, macrophages secrete and convert ATP into immunosuppressive adenosine via CD39. Moreover, we show that CD39 on macrophages is necessary to induce regulatory macrophage development and prevent severe immunopathology in a mouse model of septic shock. The next sets of data demonstrate that TLR activation also enhances A2bR expression, thus completing the CD39-initiated autoregulatory circuit to limit inflammatory macrophage responses. The second part of this work demonstrates that the chronic inflammatory disease-asociated cytokine, IFN-gamma, prevents TLR-induced A2bR expression and consequently promotes the hyper-production of inflammatory cytokines by macrophages thereby revealing a novel mechanism by which IFN-gamma; maintains overactive macrophages. The final chapter illustrates that while the A2bR is the dominant adenosine receptor mediating the inhibition of inflammatory cytokine production, A2aR signaling inhibits nitric oxide generation and that its expression may be hijacked by intracellular parasites to evade innate host defense mechanisms. Thus, this study demonstrates that inflammatory macrophage activation is inherently transient and that macrophages can reprogram themselves. These results culminate in the discovery of a novel immunomodulatory mechanism reliant on macrophage purinergic signaling and offer new targets and strategies to more effectively treat myriad inflammatory and infectious diseases
