DYNAMIC FACTORS INFLUENCING U.S. AND REGIONAL CATFISH DEMAND

Response to changes in factors influencing consumption of catfish and competing commodities differ between national, South Atlantic, and Southwest Central markets. A modified state adjustment model for catfish, beef, chicken, and other fish explicitly included age distribution, residence, occupation, education, and race/ethnic variables associated with habit formation. Nationally, per capita expenditures on catfish respond to present and past relative prices, and catfish, chicken, and other fish, but not beef, consumption demonstrates significant habit formation. South Atlantic and Southwest Central habits for catfish consumption persist, and, as the population ages, chicken and fish consumption increase.Demand and Price Analysis,

Starobinsky-type Inflation in Dynamical Supergravity Breaking Scenarios

In the context of dynamical breaking of local supersymmetry (supergravity), including the Deser-Zumino super-Higgs effect, for the simple but quite representative cases of N=1, D=4 supergravity, we discuss the emergence of Starobinsky-type inflation, due to quantum corrections in the effective action arising from integrating out gravitino fields in their massive phase. This type of inflation may occur after a first-stage small-field inflation that characterises models near the origin of the one-loop effective potential, and it may occur at the non-trivial minima of the latter. Phenomenologically realistic scenarios, compatible with the Planck data, may be expected for the conformal supergravity variants of the basic model.Comment: Five pages pdflatex, three pdf figures incorporate

Dynamical Supergravity Breaking via the Super-Higgs Effect Revisited

We investigate the dynamical breaking of local supersymmetry (supergravity), including the Deser-Zumino super-Higgs effect, via the corresponding one-loop effective potential for the simple but quite representative cases of N=1, D=4 simple supergravity and a (simplified) conformal version of it. We find solutions to the effective equations which indicate dynamical generation of a gravitino mass, thus breaking supergravity. In the case of conformal supergravity models, the gravitino mass can be much lower than the Planck scale, for global supersymmetry breaking scales below the Grand Unification scale. The absence of instabilities in the effective potential arising from the quantum fluctuations of the metric field is emphasised, contrary to previous claims in the literature.Comment: 24 pages, revtex, 4 pdf figures incorporate

Inflation via Gravitino Condensation in Dynamically Broken Supergravity

Gravitino-condensate-induced inflation via the super-Higgs effect is a UV-motivated scenario for both inflating the early universe and breaking local supersymmetry dynamically, entirely independent of any coupling to external matter. As an added benefit, this also removes the (as of yet unobserved) massless Goldstino associated to global supersymmetry breaking from the particle spectrum. In this review we detail the pertinent properties and outline previously hidden details of the various steps required in this context in order to make contact with current inflationary phenomenology. The class of models of SUGRA we use to exemplify our approach are minimal four-dimensional N=1 supergravity and conformal extensions thereof (with broken conformal symmetry). Therein, the gravitino condensate itself can play the role of the inflaton, however the requirement of slow-roll necessitates unnaturally large values of the wave-function renormalisation. Nevertheless, there is an alternative scenario that may provide Starobinsky-type inflation, occurring in the broken-SUGRA phase around the non-trivial minima of the gravitino-condensate effective potential. In this scenario higher curvature corrections to the effective action, crucial for the onset of an inflationary phase, arise as a result of integrating out massive quantum gravitino fields in the path integral. The latter scenario is compatible with Planck satellite phenomenology but not with BICEP2 data.Comment: 27 pages, pdflatex, 7 pdf figures incorporated, contains special macros (world scientific IJMPD); Invited Review, special issue IJMPD on Inflatio

WATER USERS ASSOCIATIONS IN ARMENIA: CURRENT SITUATION AND FUTURE TRENDS

Experiences of Water Consumers Cooperatives accumulated in Armenia during the past six years have been mixed. Some cooperatives have provided evidence of being capable of organizing themselves and responding to the needs of their members more effectively than any central governmental organization. However, many other aspects are still unresolved. Created in 2001, the State Committee for Water Economy (SCWE) agreed recently to follow a more participatory approach in establishment of Water Users Associations and, on the basis of positive experiences worldwide, SCWE is willing also to scale up the process to the level of Water Users Federations.Institutional and Behavioral Economics, Resource /Energy Economics and Policy,

SEASONAL LABOR CONSTRAINTS AND INTRA-HOUSEHOLD DYNAMICS IN THE FEMALE FIELDS OF SOUTHERN CAMEROON

Women's agricultural production is modeled as a sequential switching regression process determined by men's clearing labor capacity and women's harvest labor capacity. Results show that output was more often constrained by husband's clearing labor. However, men's economic contribution to household consumption is inversely related to women's agricultural output.agriculture, seasonal labor, gender, production, developing countries, Consumer/Household Economics, International Development, Labor and Human Capital,

ESTABLISHING AN AGRIBUSINESS STUDY ABROAD COURSE IN MEXICO: A PROJECT IN INTERNATIONALIZING THE CURRICULUM

Study abroad provides students with a cross-cultural experience and a new perspective on the global market place. Seven students from the University of Georgia enrolled in an initial course entitled , International Agribusiness Marketing and Management: Focus on Mexico, at the University Veracruzana in Xalapa during the Maymester 2000. Their curriculum included field trips to agribusinesses, Spanish classes and lectures on Mexican business culture, and NAFTA. As a result, students became more comfortable in cross-cultural environments and confident in their abilities.Agribusiness, Teaching/Communication/Extension/Profession,

FACTORS AFFECTING CONSUMER PREFERENCES FOR MAJOR FOOD MARKETS IN TAIWAN

The Food Industry Research and Development Institute conducted a nationwide survey of food consumption in Taiwan in 1999. A sample of 1200 consumers responded to a questionnaire, which asked whether there was a use/visit experience in the past year for each of six types of food markets: traditional vegetable market, supermarket, hypermarket, consumer cooperative, chain convenience store, and grocery store. Questions also asked which types of food markets consumers used most frequently for the purchase of fresh foods, planned purchases or occasional purchases of processed foods, and what factors influenced consumers to choose their most frequently used market. Nearly 84 percent of surveyed consumers have used/visited traditional vegetable markets in the past year, while 47 percent choose traditional markets as their most frequented marketplace for buying fresh food in Taiwan. Some 81 percent of surveyed consumers have used or visited a supermarket in past year, while 17.7 percent and 29.0 percent choose supermarkets as the most frequented marketplace for planned and occasional purchases of processed foods, respectively. We apply stepwise logistic regression to identify significant sociodemographic factors (such as gender, age, and others) which influence the choice of each of the six major types of food markets and to identify the promotional factors which positively or negatively influence consumers' preferences for the most often used market. Female consumers have almost four times higher odds of frequently using traditional vegetable markets in the past year. The unmarried, divorced/widowed, and/or those who had higher family monthly incomes demonstrate lower odds of frequently using traditional markets. For purchases of fresh foods, female respondents, older consumers, and/or those living in northern Taiwan have higher odds of choosing traditional vegetable markets as the most frequently used market, while occupation "chief," and those with higher levels of education have lower odds of choosing traditional markets. Price level influences consumers positively in choosing traditional vegetable markets, while products with mark registrations, such as GMP or CAS, negatively influence this choice. For planned purchases of processed foods, older consumers are more likely than others to choose traditional vegetable markets, and price level is also a positive influence for choosing these markets. For occasional purchases of processed foods, manual laborers and/or those living in northern Taiwan have higher odds of choosing traditional vegetable markets, while unmarried respondents have lower odds. Price level and products with nutrition labeling are positive promotional factors influencing consumers to choose traditional vegetable markets. For the other five market types, sociodemographic factors influence consumers' choices of markets differently in each case, but marketing factors also influence choices of which type of marketplace to use most frequently.Consumer/Household Economics,
