This causes an increasing importance of risk management. Farmers have a wide variety of possibilities to influence the risk exposure of their operations. Among them are the choice of the production program as well as marketing activities including forward pricing and hedging with futures and options. In total all these opportunities comprise a portfolio of activities which must be selected as to match the resources of the farm as well as the farmer's attitudes towards risk. The paper addresses this issue using a whole farm stochastic optimisation approach based on a risk-value framework. The paper starts with a discussion of risk-value models and the relationship between them and the expected utility hypothesis. In the second part the approach is incorporated in a whole farm model that optimizes a portfolio of production activities and risk management instruments. A case study...

Hispanics/Latinos in the U.S. have high cardiovascular disease risk and poorly controlled blood pressure compared to peers of European ancestry, and represent a population in need of new and innovative therapeutic approaches. As such, a focused intervention to boost psychological well-being and resilience holds promise as a novel therapeutic target for hypertension in Hispanic/Latino adults—to date, however, no research explores whether a causal link is evident. OBJECTIVE The aim of the current study is to detail the study protocol of the ¡Alégrate! [Be Happy!] intervention, a Phase II randomized controlled trial (RCT) testing efficacy in improving blood pressure of a Web-based positive psychological...
