Strengthening the Competitive Position of Commodity Marketers Two Case Study Approaches

Producers and marketers of agricultural commodities are often beset with a similar set of problems that generally may be reduced to the following question: "how can we modify our product or program in such a way as to gain a competitive edge on our competition?" As every commodity marketer knows, there is, unfortunately, no easy answer to this question. Obtaining higher prices and returns for agricultural products is possible, but requires commitment, vision and attention to the ever-changing marketplace. The current monograph contains two case studies that approach this perennial question from different agricultural commodity industries--fresh produce and turkeys--that are surrounded by different sets of basic supply and demand conditions. Yet, in each case, the companies depicted have been particularly aggressive in their approach to marketing and at least moderately successful in their quest for higher producer returns. Both of these cases are based on real companies and current data. In the first instance, TruFresh International (TFI) has been substituted for the company's actual name but the circumstances documented in the case have not been altered, and in the second example, Plainville Turkey Farm (PTF) is indeed the name of the firm. The story of each is instructive in a different way. Simply put, TFI, long an innovator in fresh produce marketing, is confronted with the challenge that several of its competitors are beginning to duplicate certain of its most successful product and market innovations. The case focuses on the strategic alternatives that TFI may have at its disposal to address this problem, typical to so many commodity industries. In the second instance, PTF is faced with a related but narrower issue: the PTF brand of fresh turkey products has been received enthusiastically in Central New York State as a high quality brand and one for which consumers have demonstrated a willingness to pay a premium. The dilemma for PTF is whether, and with what strategy, should it attempt to expand its well established branded line of turkey products to new regions and new markets? Both of these firms are confronted with a set of marketing challenges that will sound familiar to nearly all commodity-based companies. In discussing the events that led to the situations faced by these two companies and the strategic options available to address them, students, executives and industry practitioners will gain an improved understanding of the process involved in adding value to differentiate agricultural commodities.Marketing,

The Interaction of Life Sciences & Engineering Technologies in Man/Systems Integration

Advancing technology has led to increasingly sophisticated systems, requiring cooperative interdisciplinary solutions to achieve optimal man/system integration. The life sciences and engineering have started to exchange ideas, techniques, and approaches to this common problem area. The difficulties encountered in such relationships are largely a matter of tradition and the absence of dialogue rather than any basic technical incompatibility. A basis for resolving these differences and the results of such endeavors are discussed

Stress at deformations beyond the elastic limit for compression perpendicular to the grain in hem-fir

Allowable stresses in compression perpendicular to the grain (C-perp) have been too conservative for most structural uses. This study develops stress data for deformations beyond the proportional limit (PL), up to 0.1 inch for hem-fir. Fifteen boards from four western states were cut into small specimens representing three ring angle classes (0, 45 and 90 degrees) and one large specimen with varying ring angle. Specimens with ring angle of about 45 degrees were the weakest. Stresses for large specimens and small specimens with 45-degree ring angle were remarkably similar. Stresses in C-perp continually increase beyond PL to at least 0.1 inch deformation without any noticeable failure. If allowable stresses in C-perp were accepted beyond PL, acceptable deformation would then be the new design specification

Supermarket Bakery Consumers: Attitudes, Preferences, Behaviors

R.B. 95-01For at least a decade, supermarket operators have turned increasingly to fresh foods for the strategic direction of their business by remodeling existing stores and building new stores to feature and emphasize produce, the delicatessen, the bakery, and other perishable departments. These departments have been the fastest growing and offer the greatest future sales potential as consumer demand for fresh and ready to eat prepared foods continues to grow. Despite these prospects, little is actually known about how consumers perceive and respond to product offerings and retailer initiatives in perishable departments. The objective ofthis report is to shed light on consumer attitudes and behavior with respect to one of the major supermarket perishable departments: the bakery. This report is based on a study which incorporated both primary and secondary sources of data (details in Section II). The primary data were collected through consumer surveys conducted nationwide by telephone and in-person at supermarkets in several regional market areas. A total of 700 consumers were surveyed. Additional primary data and insights were gathered through personal interviews with key supermarket bakery executives. Secondary data were gathered from trade reports, academic journals, and previously published research. The empirical results and analyses presented in Section III include such key findings as: • consumers consider convenience the most important reason for shopping supermarket bakeries, • the main reason some consumers do not buy baked goods in supermarkets is freshness, which is perceived to be better at local bakeries, • consumer awareness of health and nutrition concerns is greater than consumer knowledge about these issues, • about half of consumers are familiar with the United States Department of Agriculture's Food Guide Pyramid, but the percentage varies greatly by age with the youngest shoppers being most familiar, • consumers rate many of the most popular retailer promotional efforts as uninfluential factors in their purchase decisions, and • price plays only a minor role in bakery purchase decisions for most consumers. The implications of these findings and others are discussed in Section IV which also discusses opportunities for the supermarket bakery industry to respond to the consumer characteristics and issues identified in this study. The results present many marketing challenges for supermarket bakery managers as consumers increasingly make bakery decisions based on knowledge of health, nutrition, and other issues

Biological and chemical assessment of zinc ageing in field soils

As zinc (Zn) is both an essential trace element and potential toxicant, the effects of Zn fixation in soil are of practical significance. Soil samples from four field sites amended with ZnSO4 were used to investigate ageing of soluble Zn under field conditions over a 2-year period. Lability of Zn measured using 65Zn radioisotope dilution showed a significant decrease over time and hence evidence of Zn fixation in three of the four soils. However, 0.01 M CaCl2 extractions and toxicity measurements using a genetically modified lux-marked bacterial biosensor did not indicate a decrease in soluble/bioavailable Zn over time. This was attributed to the strong regulatory effect of abiotic properties such as pH on these latter measurements. These results also showed that Zn ageing occurred immediately after Zn spiking, emphasising the need to incubate freshly spiked soils before ecotoxicity assessments. Ageing effects were detected in Zn-amended field soils using 65Zn isotopic dilution as a measure of lability, but not with either CaCl2 extractions or a lux-marked bacterial biosensor

Allosteric Inhibition of Human Ribonucleotide Reductase by dATP Entails the Stabilization of a Hexamer

Ribonucleotide reductases (RNRs) are responsible for all de novo biosynthesis of DNA precursors in nature by catalyzing the conversion of ribonucleotides to deoxyribonucleotides. Because of its essential role in cell division, human RNR is a target for a number of anticancer drugs in clinical use. Like other class Ia RNRs, human RNR requires both a radical-generation subunit (β) and nucleotide-binding subunit (α) for activity. Because of their complex dependence on allosteric effectors, however, the active and inactive quaternary forms of many class Ia RNRs have remained in question. Here, we present an X-ray crystal structure of the human α subunit in the presence of inhibiting levels of dATP, depicting a ring-shaped hexamer (α[subscript 6]) where the active sites line the inner hole. Surprisingly, our small-angle X-ray scattering (SAXS) results indicate that human α forms a similar hexamer in the presence of ATP, an activating effector. In both cases, α[subscript 6] is assembled from dimers (α[subscript 2]) without a previously proposed tetramer intermediate (α[subscript 4]). However, we show with SAXS and electron microscopy that at millimolar ATP, the ATP-induced α[subscript 6] can further interconvert with higher-order filaments. Differences in the dATP- and ATP-induced α[subscript 6] were further examined by SAXS in the presence of the β subunit and by activity assays as a function of ATP or dATP. Together, these results suggest that dATP-induced α[subscript 6] is more stable than the ATP-induced α6 and that stabilization of this ring-shaped configuration provides a mechanism to prevent access of the β subunit to the active site of α.National Institutes of Health (U.S.) (GM100008)National Institutes of Health (U.S.) (Grant GM29595)Massachusetts Institute of Technology.

A review of DNA risk alleles to determine epigenetic repair of mRNA expression to prove therapeutic effectiveness in reward deficiency syndrome (RDS): Embracing Precision Behavioral Management

This is a review of research on Precision Behavioral Management of substance use disorder (SUD). America is experiencing a high prevalence of substance use disorder, primarily involving legal and illegal opioid use. A 3000% increase in treatment for substance abuse has occurred between 2000 and 2016. Unfortunately, present day treatment of opioid abuse involves providing replacement therapy with powerful opioids to, at best, induce harm reduction, not prophylaxis. These interventions do not enhance gene expression and restore the balance of the brain reward system\u27s neurotransmitters. We are proposing a generalized approach called Precision Behavioral Management . This approach includes 1) using the Genetic Addiction Risk Severity (GARS, a 10 candidate polymorphic gene panel shown to predict ASI-alcohol and drug severity) to assess early pre-disposition to substance use disorder; 2) using a validated reward deficiency syndrome (RDS) questionnaire; 3) utilization of the Comprehensive Analysis of Reported Drugs (CARD™) to assess treatment compliance and abstinence from illicit drugs during treatment, and, importantly; 4) utilization of a Pro-dopamine regulator (KB220) (via IV or oral [KB220Z] delivery systems) to optimize gene expression, restore the balance of the Brain Reward Cascade\u27s neurotransmitter systems and prevent relapse by induction of dopamine homeostasis, and; 5) utilization of targeted DNA polymorphic reward genes to direct mRNA genetic expression profiling during the treatment process. Incorporation of these events can be applied to not only the under-considered African-American RDS community, but all victims of RDS, as a demonstration of a paradigm shift that uniquely provides a novel putative standard of care based on DNA guided precision nutrition therapy to induce dopamine homeostasis and rebalance neurotransmitters in the Brain Reward Cascade. We are also developing a Reward Deficiency Syndrome Diagnostic Criteria (RDSDC) to assist in potential tertiary treatment
