A further step into the ELGH and TLGH for Spain and Italy AgEcon
Cortes-Jimenez, Isabel; Pulina, Manuela.
Nowadays many developing countries focus on economic policies for promoting international tourism and exports expansion as a potential source of economic growth of the country. However, the understanding of the relationship between exports and economic growth is still ongoing. When treating the relationship between tourism and economic growth, considering tourism as a non-traditional export few studies have been published to date. This paper has the objective to assess if exports and tourism have really promoted growth by means of the export-led growth hypothesis (ELGH) and the tourism-led growth hypothesis (TLGH). The cases under analysis are Spain and Italy, two of the most important countries worldwide regarding the expansion of tourism. Cointegration...

A Future for the Dead Sea Basin: Water Culture among Israelis, Palestinians and Jordanians AgEcon
Lipchin, Clive.
The Dead Sea basin plays a major role for regional economic development (industry, tourism and agriculture) in the Middle East. This potential is threatened by the steady disappearance of the Dead Sea. Since around 1930 the water level of the Dead Sea has fallen by about 25 m, about half of this alone in the last 20 years. The Dead Sea is a transboundary resource shared by Israel, the Palestinian Authority and Jordan. The Dead Sea is the terminal point of the Jordan River watershed and as such, it serves as a barometer for the health of the overall system. Its rapid decline reflects the present water management strategies of the riparian and upstream countries. This includes the different water cultures of the three countries. Throughout history, the Dead...

A Fuzzy Logic Controller for Autonomous Wheeled Vehicles InTech
Mohamed B. Trabia; Linda Z. Shi; Neil E. Hodge.
This chapter presents a fuzzy logic control system for steering a two-axle vehicle. Two controllers are presented individually: the steering controller and the velocity controller. Each fuzzy controller is divided into several modules to represent the distributed way in which humans deal with different driving tasks. All of these modules are of the Mamdanitype and use sigmoid or product of sigmoid membership functions. The outputs of the various modules are added together to control the steering angle and the speed of the vehicle, respectively. Two fuzzy modules in the steering controller are designed to meet the basic driving requirement: Target Steering Fuzzy module and Collision Avoidance Steering Fuzzy module. The first module steers the vehicle toward...

A gap analysis of confined field trial application forms for genetically modified crops in East Africa: evaluating the potential for harmonization AgEcon
Linacre, Nicholas A.; Cohen, Joel I..
The regulatory approval of genetically modified crops in the field initially requires small, restricted experimental trials known as confined field trials. These small scale experiments provide researchers with important information on environmental interactions and agronomic performance of the crop in a safe and contained manner. To authorize confined field trials regulatory review is required, with formats for obtaining relevant information differing from country to country. In this paper, a Gap Analysis is used to identify informational gaps and potential for harmonization of confined field trial application processes in three East African countries - Tanzania, Kenya, and Uganda. The basic principle behind gap analysis is a comparison of the status quo...

A general eco-evolutionary framework for understanding bioinvasions Inra
Facon, B.; Genton, B.J.; Shykoff, J.; Jarne, P.; Estoup, A.; David, P..
Studies of bioinvasions have revealed various strategies of invasion, depending on the ecosystem invaded and the alien species concerned. Here, we consider how migration (as a demographic factor), as well as ecological and evolutionary changes, affect invasion success. We propose three main theoretical scenarios that depend on how these factors generate the match between an invader and its new environment. Our framework highlights the features that are common to, or differ among, observed invasion cases, and clarifies some general trends that have been previously highlighted in bioinvasions. We also suggest some new directions of research, such as the assessment of the time sequence of demographic, genetic and environmental changes, using detailed temporal...

A General Equilibrium Analysis of Foreign and Domestic Demand Shocks Arising from Mad Cow Disease in the United States AgEcon
Devadoss, Stephen; Holland, David W.; Stodick, Leroy; Ghosh, Joydeep.
The discovery of the first case of mad cow disease in the United States in 2003 reverberated across the beef and cattle industry. This study employs a general equilibrium model to analyze the potential economic effects of mad cow disease on the beef, cattle, and other meat industries under three scenarios, ranging form most favorable to most pessimistic. The scenario with 90% foreign demand decline and 10% domestic demand reduction generates results consistent with the actual outcomes after the mad cow disease outbreak. Only if domestic demand declines significantly will the economic hardship in the U.S. beef and cattle industry be very large.

A Global Hunger Index: Measurement Concept, Ranking of Countries, and Trends AgEcon
Wiesmann, Doris M..
Progress in combating hunger and undernutrition has been lagging for decades. Best practices to fight hunger and undernutrition have been available for a long while, but lack of political will among leaders and a lack of political power among the poor have hampered their implementation. Since indices have proven to be powerful tools for advocacy and are able to capture multifaceted phenomena, the Global Hunger Index (GHI) was developed to increase attention to the hunger problem and mobilize the political will to speed up urgently needed progress in the fight against hunger. The GHI captures three dimensions of hunger: insufficient availability of food, shortfalls in the nutritional status of children, and child mortality, which is to a large extent...

A global view of genetic diversity in cultivated sorghums using a core collection Inra
Deu, M.; Rattunde, F.; Chantereau, J..
Une analyse approfondie de la structuration de la diversité génétique des sorghos cultivés est présentée. Une core collection de 210 variétés représentatives de la diversité des races, latitudes, réponses à la durée du jour et systèmes de culture a été analysée au moyen de 74 sondes PLFR réparties sur le génome. Les analyses multivariées ont montré la spécificité des guinea margaritiferum ainsi qu’une structuration géographique et raciale de la diversité génétique. L’analyse « neighbour joining » a montré une différenciation entre variétés africaines du nord et du sud de l’équateur. La présence de variétés asiatiques dans chacun de ces grands pôles géographiques d’évolution des sorghos indique 2 introductions en Asie. La race est aussi un des facteurs...

A Handful of Heuristics and Some Propositions for Understanding Resilience in Social-Ecological Systems Ecology and Society
Walker, Brian; CSIRO; Brian.Walker@csiro.au; Gunderson, Lance; Emory Universitry; lgunder@emory.edu; Kinzig, Ann; Arizona State University; Ann.Kinzig@asu.edu; Folke, Carl; Stockholm University; calle@system.ecology.su.se; Carpenter, Steve; University of Wisconsin; srcarpen@wisc.edu; Schultz, Lisen; Stockholm University; lisen@ecology.su.se.
This paper is a work-in-progress account of ideas and propositions about resilience in social-ecological systems. It articulates our understanding of how these complex systems change and what determines their ability to absorb disturbances in either their ecological or their social domains. We call them “propositions” because, although they are useful in helping us understand and compare different social-ecological systems, they are not sufficiently well defined to be considered formal hypotheses. These propositions were developed in two workshops, in 2003 and 2004, in which participants compared the dynamics of 15 case studies in a wide range of regions around the world. The propositions raise many questions, and we present a list of...

A Hedonic Analysis of Cattle Prices in the Central Corridor of West Africa: Implications for Production and Marketing Decisions AgEcon
Williams, Timothy O.; Okike, Iheanacho; Spycher, Ben.
Detailed weekly sales transactions data for the period January 2000-June 2001 from three frontier markets in the central corridor of West Africa were analyzed to identify the factors influencing short-run, intra-year cattle prices. The empirical results indicate that in addition to market location and seasonality of supply and sales, market participants show systemic preferences for specific cattle attributes (sex, weight, condition and finish) and are willing to pay premium prices consistent with their preferences. Communicating this information to producers can assist them to tailor their production and marketing decisions to meet market expectations and thereby improve their competitiveness, profitability and intra-regional livestock trade. Innovative...

A Hedonic Analysis on the Implicit Values of Fresh Tomatoes AgEcon
Huang, Chung L.; Lin, Biing-Hwan.
The food habits and dietary patterns of American consumers are changing and they are increasingly demanding food products that possess certain attributes relating to how the food was produced or processed. The objectives of the study are to analyze household purchase of fresh tomatoes and to determine the magnitudes of the price premium paid for the organic tomatoes by estimating a hedonic price model. The study uses the 2003 ACNielsen Homescan panel data. The data set represents a nationally representative panel of U.S. households, which provide food purchase data for at-home consumption. For empirical implementation, parameters of the hedonic model were estimated using the Box-Cox transformation procedure. The results indicated that consumers value the...

A hedonic approach to estimating the supply of variety attributes of a subsistence crop AgEcon
Edmeades, Svetlana.
The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country. The model is applied to bananas in Uganda, making use of disaggregated data on variety-specific farm-gate banana bunch prices and attributes. The hedonic analysis is applied at the farm-gate, the first link in the market chain, while accounting for the semi-subsistence nature of banana producing households. Within the framework of the agricultural household, where consumption and production decisions are non-separable, prices reflect the implicit marginal valuation of both consumption and production attributes jointly. The paper is motivated by the need to quantify the value of...
