SUPPLY CHAIN MANAGEMENT IN PERISHABLES: A PRODUCE APPLICATION

The objective of supply chain management (SCM) is to remove time and cost from supply chains, improving profitability and/or competitiveness. It is possible through conceptual advances, utilization of computer hardware and software, and other advances in electronic technology. Business literature is used to define the concept. Most applications and benefits have resulted from alliances between large retailers and large packaged goods vendors. Specific applications of SCM in the produce industry, with emphasis on factors such as perishability and production variability, are discussed. Firm-size implications are important. While small and mid-sized growers may find the cost to be high, the innovation of logistics provided by outside suppliers is an alternative. A third-party provider was interviewed; its approach and services are documented; and industry implications are discussed.Agribusiness,

The depth of the convective boundary layer and implications for a Walker-like circulation on Mars

Radio science observations indicate that the depth of the martian convective boundary layer varies strongly with surface height, although the surface temperature does not. We show that this effect is reproduced in martian limited area models and in global climate models. The implications for the global circulation when convective boundary layer depth varies with location are considered

IMPACT OF SOCIOECONOMIC CHARACTERISTICS ON ATTITUDES TOWARD FOOD IRRADIATION

Irradiation of food products is one of several techniques that reduce the risk of food-borne illness. Despite its advantages, the technique has been used sparingly because consumers are wary about this technology. A logit model is used to evaluate the impacts of demographic factors on attitudes toward purchasing foods that have been irradiated and toward paying more for irradiated foods. An important finding of this study is that consumers who are familiar with irradiation are significantly more likely to buy and pay more for irradiated products than those who have never heard of irradiation. This implies that educational programs aimed at informing consumers about the benefits of irradiation can work.Consumer/Household Economics, Food Consumption/Nutrition/Food Safety,

Martian meso/micro-scale winds and surface energy budget

Regional, diurnal and seasonal variations of surface temperature are particularly large on Mars. This is mostly due to the Martian surface remaining close to radiative equilibrium. Contrary to most terrestrial locations, contributions of sensible heat flux (i.e. conduction/convection exchanges between atmosphere and surface) to the surface energy budget [hereinafter SEB] are negligible on Mars owing to lowatmospheric density and heat capacity (e.g. Figure 2 in Savijärvi and Kauhanen, 2008). This radiative control of surface temperature is a key characteristic of the Martian environment and has crucial consequences on the the Martian geology, meteorology, exobiology, etc. In order to identify the impact of this Martian peculiarity to near-surface regional-to-local atmospheric circulations, we employ our recently-built Martian limited-area meteorological model (Spiga and Forget, 2009). We use horizontal resolutions adapted to the dynamical phenomena we aim to resolve: from several tens of kilometers to compute regional winds (mesoscale simulations) to several tens of meters to compute atmospheric boundary-layer winds (microscale or turbulent-resolving simulations, also called Large-Eddy Simulations, LES)

Research Notes : United States : A greenhouse method of screening soybeans for resistance to Fusarium wilt

Fusarium wilt of soybean (causal organism: Fusarium oxysporum Schlecht. emend. Snyd. & Hans.) has become an increasingly severe disease in the breed-ing plots at Gainesville and may be an undiagnosed or misdiagnosed problem in soybean production fields. At Gainesville, severity of Fusarium wilt, or a complex which includes F. oxysporum, has reduced yields in some plots to near-ly zero
