Thermalization of plastic flow versus stationarity of thermomechanical equilibrium in SGR theory
We discuss issues related to thermalization of plastic flow in the context of
soft glassy rheology (SGR) theory. An apparent problem with the theory in its
current form is that the stationarity of thermomechanical equilibrium obtained
by requiring that its flow rule satisfy detailed balance in the absence of
applied deformation requires plastic flow to be athermal. This prevents proper
application of SGR to small-molecule and polymer glasses where plastic flow is
often well-thermalized. Clearly, one would like to have a SGR-like theory of
thermalized plastic flow that satisfies stationarity. We discuss reasons why
such a theory could prove very useful and clarify obstacles that must be
overcome in order to develop it.Comment: substantially revised in response to referee comment
Structure and dynamics of model colloidal clusters with short-range attractions
We examine the structure and dynamics of small isolated -particle clusters
interacting via short-ranged Morse potentials. "Ideally preprared ensembles"
obtained via exact enumeration studies of sticky hard sphere packings serve as
reference states allowing us to identify key statistical-geometrical properties
and to quantitatively characterize how nonequilibrium ensembles prepared by
thermal quenches at different rates differ from their equilibrium
counterparts. Studies of equilibrium dynamics show nontrival temperature
dependence: nonexponential relaxation indicates both glassy dynamics and
differing stabilities of degenerate clusters with different structures. Our
results should be useful for extending recent experimental studies of small
colloidal clusters to examine both equilibrium relaxation dynamics at fixed
and a variety of nonequilibrium phenomena.Comment: Noro-Frenkel analysis added. Published in PR
Stories of Mothers and Child Welfare (SUMMARY REPORT)
The voices we hear describing the lives of mothers who come into contact with child welfare agencies are usually those of service providers and researchers. How do mothers make sense of their own lives and what happened to their families when they became involved with child welfare? This report provides an opportunity to listen to what 16 of these mothers had to say over conversations averaging 5 - 6 hours with each woman. Aspects of these stories will be familiar to some readers. Nonetheless, these stories challenge both popular and professional perceptions of who these mothers are and how they confront the obstacles in their lives. The stories also ask us to consider how we might make our helping more welcome and congruent with the lives of these mothers, their children and families. (Full version of report also available.

A chronic disease outreach program for Aboriginal communities
Background. Our objective is to describe a program to improve awareness and management of hypertension, renal disease, and diabetes in 3 remote Australian Aboriginal communities. Methods. The program espouses that regular integrated checks for chronic disease and their risk factors are essential elements of regular adult health care. Programs should be run by local health workers, following algorithms for testing and treatment, with backup, usually from a distance, from nurse coordinators. Constant evaluation is essential to develop community health profiles and adapt program structure. Results. Participation ranged from 65% to 100% of adults. Forty-one percent of women and 72% of men were current smokers. Body weight varied markedly by community. Although excessive in all, rates of chronic diseases also differed markedly among communities. Rates increased with age, but the greatest numbers of people with morbidities were middle age and young adults. Multiple morbidities were common by middle age. Hypertension and renal disease were early features, whereas diabetes was a variable and later manifestation of this integrated chronic disease syndrome. Adherence to testing and treatment protocols improved markedly over time. Substantial numbers of new diagnoses were made. Blood pressure improved in people in whom antihypertensive agents were started or increased. Components of a systematic activity plan became more clearly defined with time. Treatment of people in the community with the greatest disease burden posed a large additional workload. Lack of health workers and absenteeism were major impediments to productivity. Conclusion. We cannot generalize about body habitus, and chronic disease rates among Aboriginal adults. Pilot data are needed to plan resources based on the chronic disease burden in each community. Systematic screening is useful in identifying high-risk individuals, most at an early treatable stage. Community-based health profiles provide critical information for the development of rational health policy and needs-based health services
Marketing the Mediterranean Diet: Some Comments on Issues and Opportunities
"The Mediterranean Diet" is a commonly used term in the U.S. denoting healthful eating and a healthy lifestyle. It appears to be inspired by the traditional diets of two Mediterranean countries based on post-World War II studies conducted in Naples, Italy and Crete. Popularization of the Mediterranean diet is associated with increased demand for red wine and olive oil in the United States. As noted in the American Heart Association (AHA) website, there is no one "Mediterranean" diet. The Mediterranean diet, as typically presented, appears to be inspired by traditional diets in Southern Italy, Greece, and Spain. The AHA outlines the common characteristics of the Mediterranean dietary pattern. At least two non-profit organizations promote their version of a Mediterranean diet pyramid, and hundreds of books present their version of the Mediterranean diet. There appears to be an outstanding opportunity for a well-funded and motivated organization to effectively market a Mediterranean diet plan, based on accepted marketing models. Research on market segments, product definition and product positioning will be required. Questions to be considered relate to the effectiveness of diet pyramids, diet benefits sought by various consumer segments, and the medical and health benefits of individual food products as documented by medical and nutrition research. Examples of the health and nutrition research and promotion programs for four California commodity groups provide information on an alternative approach to presenting information on diet and health.Food Consumption/Nutrition/Food Safety,
CALIFORNIA MILK MARKETING MARGINS
This article uses monthly price data to estimate farm-retail price response equations for three California market areas. The results indicate that there is a strong direct relationship between retail and farm-level milk prices-retailers increase and decrease their prices equally in response to f.o.b. price increases and decreases. While the total retail response to farm price increases and decreases is equal, the timing of the adjustments is not. Farm price increases during a given month led to retail price increases during the same month while farm price decreases were not fully reflected in retail prices until the following month.Marketing,
