Although much has been written about the complexity of educational change and reform elsewhere, the educational reform movement in the United Arab Emirates (UAE) is a relatively recent phenomenon with little systematic documentation as yet; educators are still searching for a clear understanding of their roles. However, it is clear that the leadership of the country is exerting great pressure for reform in schools and there is a sense of urgency about the need for largescale change. This article examines the impact of these reforms on the work of one school principal at this time of radical transformation. It begins with a brief review of some of the specific changes taking place in the emirate of Abu Dhabi including the introduction of a public private partnership model in public schools and a brief discussion of the role of school principals in the management of change. This is followed by a description of the study and the methodological design underpinning it. The findings of the study are presented and discussed and the article concludes with some recommendations for further research.

SUMMARYThe objectives of this study were to determine the prevalence of scabies in an infested village; to educate the residents on self-treatment and prevention by the use of 5% monosulfiram soap; to evaluate the short term effectiveness of this intervention by determining, 2 weeks later, the compliance to self-treatment and prevention; and to determine the prevalence rate on the second visit. In 59 households (967 % of the village) containing 313 persons, an educational session was held and a leaflet distributed on the use and availability of the soap. Thirteen persons (4-2 %) from eight households (13-6 %) had scabies. After 2 weeks, 7 persons (2-2 %) (2 persisting and 5 new cases) from 5 households (8-5 %) were infested. Thus a cure rate of 85 % was obtained though the prevalence rate showed no statistically significant difference. Among the under 15 year olds, the numbers infected decreased from 10 to 3 while among the over 15 year olds, the numbers infected increased from 3 to 4, neither reading significance at the 5 % level.

Before 2011 rates of hospitalization for heart attacks were about the same in San Diego County as they were in the rest of California. In 2011 a multistakeholder population health collaborative consisting of partners at the federal, state, and local levels launched Be There San Diego. The collaborative's goal was to reduce cardiovascular events through the spread of best practices aimed at improving control of hypertension, lipid levels, and blood sugar and through patient and medical community activation. Using hospital discharge data for the period 2007-16, we compared acute myocardial infarction (AMI) hospitalization rates in San Diego County and the rest of the state before and after the demonstration project started. AMI hospitalization rates decreased by 22 percent in San Diego County versus 8 percent in the rest of the state, with an estimated 3,826 AMI hospitalizations avoided and $86 million in savings in San Diego. Results show that a science-based health collaborative can improve outcomes while lowering costs, and efforts are under way to ensure the collaborative's sustainability.
