Workers' Compensation Insurance In North America: Lessons for Victoria?

Among the issues we will consider here are the following. Who carries the underwriting(insurance) risk for workers' compensation benefits? How is workers' compensation insuranceprices, and by whom? What fundamental principles guide the insurance pricing system? Whomonitors benefits for compliance with statutory requirements? Are the availability of coverageand the payment of insurers' claims obligations guaranteed? Is self-insurance allowed and, if so, for whom? How are incentives for prevention of accidents, and resulting workers' compensation claims, maintained? What is the performance of the overall system? In summary, how are these questions answered and what so the answers reveal about how these responsibilities are allocated among government agencies, other public entities and private firms

IMPACTS OF GLOBAL WARMING ON CROPPING PRACTICES IN ALBERTA

A Target MOTAD farm-level model was developed to assess the expected impacts from global warming on representative grain and oilseed farms in Alberta. It was found that a warmer climate would increase crop yields and length of the cropping season. Net returns and shadow values of land would increase substantially. Price risk generally was more important than yield risk under simulated warmer climates.Environmental Economics and Policy,

Principal-Agent Relationships in Agricultural Cooperatives: An Empirical Analysis from Rural Alberta

Cooperatives throughout North America are consolidating at an increasing rate and for a variety of reasons. While many cooperatives merge with others or are acquired to achieve greater economies of scale, several fail due to changes in the external economy, which make them redundant. Often, such redundancy is reflected in a heightened sense of member dissatisfaction. Many argue that such dissatisfaction is likely to arise in cooperatives as a result of principal-agent problems. In order to determine whether or not cooperative managers maintain the same goals as their owners, this study uses data from a member-survey to compare Alberta cooperative members' objectives with those they believe to be held by their cooperatives' managers. An econometric model of the difference between members' expectations and perceptions shows how various socioeconomic variables affect the extent to which these objectives are aligned. The results of this analysis can help cooperative boards design managerial incentive programs to better align their goals with those of the cooperative membership.Agribusiness,

A practical guide to assessment of ventricular diastolic function using doppler echocardiography

AbstractDoppler assessment of diastolic function has become a standard part of routine echocardiographic examination and imparts information relevant to a patient's functional class, management and prognosis. This review describes the Doppler patterns of diastolic function relative to physical signs and physiology. A continuum of Doppler patterns of diastolic function exists, including normal diastolic function, impaired relaxation, pseudonormal filling, restriction, constriction and tamponade. These patterns evolve from one to another in a single individual, with changes in disease evolution, treatment and loading conditions. New applications of continuous wave Doppler, color Doppler M-mode and Doppler tissue imaging are refining our understanding of diastolic function
