COMPARING THE PROFITABILITY OF CASSAVA-BASED PRODUCTION SYSTEMS IN THREE WEST AFRICAN COUNTRIES: COTE D'IVOIRE, GHANA AND NIGERIA

Sub-Saharan Africa (SSA) cassava-producing countries such as Nigeria, Ghana, and Côte d'Ivoire have developed, in recent years, a renewed interest in cassava as an alternative food crop. This has led to a major expansion in cassava-based production systems in Nigeria and Ghana, whereas there has been a slower growth in Côte d'Ivoire (Nweke et al., 1998). This paper is based on the argument that the difference in various factors such as agricultural policies (i.e., trade and price policies, domestic production taxes or subsidies), location and technologies (production and processing) between Nigeria, Ghana and Côte d'Ivoire the difference in the level of growth in cassava-based production systems. The paper examines, using the Policy Analysis Matrix (PAM), the magnitude of the impact of these factors on the private and social profitability of cassava production and post-production processing in Côte d'Ivoire, Ghana and Nigeria. The topic has not been examined in previous studies. The paper relies primarily on data for Côte d'Ivoire, Ghana and Nigeria from the Collaborative Study of Cassava in Africa (COSCA) survey. The baseline results demonstrate the similarity in efficiencies of production in these West African countries. The simulation findings indicated that, in Côte d'Ivoire, farmers benefited from the depreciation of the equilibrium exchange rate while farmers in Ghana and Nigeria suffered losses. Simulation results also indicated that Ivorian and Ghanaian cassava/maize farmers could benefit from growing IITA's improved variety and adopting mechanized processing methods.Crop Production/Industries,

EQUINE CLIENT SATISFACTION AT THE VETERINARY TEACHING HOSPITAL, MICHIGAN STATE UNIVERSITY--JULY 1, 1999 THROUGH JUNE 30, 2000

Understanding clients' wants and needs is vital to the sustained success of any service business, and veterinary medicine offers no exception. The Veterinary Teaching Hospital (VTH) at the Michigan State University College of Veterinary Medicine (MSU-CVM) has successfully maintained a position at the forefront of the veterinary profession throughout most of its history. The staff has consistently been composed of clinicians who have been chosen because of their excellence and expertise. However, the assumption that emphasis on clinical excellence will, by itself, provide the foundation for sustained success in the client flow and business at the hospital has been unchallenged to date. In order to provide the best possible customer service, our clients' likes, dislikes, wants, and needs must be fully characterized and quantified. To assess client satisfaction with the VTH, a study was designed whose objective was to identify the areas in the VTH that are most valued and highly regarded versus those that need improvement in order to sustain the current success of the equine hospital. The results of this study can be used as an outline for the development of a plan to maintain and improve customer satisfaction and, ultimately, to sustain the teaching caseload and business of the hospital. In addition, this endeavor will serve to set a good example for our students by modeling the best management practices and establishing a critical blend of quality medicine/surgery and customer service.Teaching/Communication/Extension/Profession,

Interplay between interferences and electron-electron interactions in epitaxial graphene

We separate localization and interaction effects in epitaxial graphene devices grown on the C-face of a 4H-SiC substrate by analyzing the low temperature conductivities. Weak localization and antilocalization are extracted at low magnetic fields, after elimination of a geometric magnetoresistance and subtraction of the magnetic field dependent Drude conductivity. The electron electron interaction correction is extracted at higher magnetic fields, where localization effects disappear. Both phenomena are weak but sizable and of the same order of magnitude. If compared to graphene on silicon dioxide, electron electron interaction on epitaxial graphene are not significantly reduced by the larger dielectric constant of the SiC substrate

EQUINE REFERRING VETERINARIAN SATISFACTION WITH THE VETERINARY TEACHING HOSPITAL, MICHIGAN STATE UNIVERSITY - JULY 1, 1999 THROUGH JUNE 30, 2000

Understanding clients' wants and needs is vital to the sustained success of any service business, and veterinary medicine offers no exception. The Veterinary Teaching Hospital (VTH) at the Michigan State University College of Veterinary Medicine (MSU-CVM) has successfully maintained a position at the forefront of the veterinary profession throughout most of its history. The staff has consistently been composed of clinicians who have been chosen because of their excellence and expertise. However, the assumption that emphasis on clinical excellence will, by itself, provide the foundation for sustained success in the client flow and business at the hospital has been unchallenged to date. Additionally, there are many areas in veterinary medicine that are becoming increasingly popular (e.g. oncology). Addition of, or attention to, these services is crucial in retaining our leadership role within the veterinary community. The results of a previous study indicated that 75.4% of equine clients chose MSU-VTH because they were referred by their primary veterinarian. One of the objectives of this study was to determine which factors influenced referring veterinarians in determining whether they refer their patients to MSU-VTH. Additionally, this study was designed to identify areas for possible expansion/contraction of our current service offerings in order to better serve the needs of our clients and referring veterinarians. The results of this study can be used as an outline for the development of a plan to maintain and improve referring veterinarian satisfaction and, ultimately, to sustain the teaching caseload and business of the hospital. In addition, this endeavor will serve to set a good example for our students by modeling the best management practices and establishing a critical blend of quality medicine/surgery and customer service.Teaching/Communication/Extension/Profession,

PRICES AND PRICING POLICIES FOR SMALL ANIMAL AND EQUINE VETERINARY SERVICES: A STUDY OF TEACHING HOSPITALS AND MICHIGAN PRIVATE PRACTICES DURING 2000

Prices are a key determinant of financial performance for virtually any business in either the public or private sector, and the Veterinary Teaching Hospital at Michigan State University (MSU-VTH) offers no exception. To achieve consistent success, it is critical that a business understands the prevailing conditions in the marketplace when setting prices for its goods and services. Important issues to address include: 1. What are the prices of similar goods and services produced by other firms? 2. How important is price as a choice factor when customers select a source of these goods and services? 3. How do staff members view prices at the point-of-sale? 4. How are prices determined? These questions are especially crucial in small businesses such as those typical of the veterinary profession, where the decision-makers tend to be technical experts rather than trained business managers. Without this information, these decision-makers often have very little basis on which to develop a pricing policy.Teaching/Communication/Extension/Profession,

Growth of monolayer graphene on 8deg off-axis 4H-SiC (000-1) substrates with application to quantum transport devices

Using high temperature annealing conditions with a graphite cap covering the C-face of an 8deg off-axis 4H-SiC sample, large and homogeneous single epitaxial graphene layers have been grown. Raman spectroscopy shows evidence of the almost free-standing character of these monolayer graphene sheets, which was confirmed by magneto-transport measurements. We find a moderate p-type doping, high carrier mobility and half integer Quantum Hall effect typical of high quality graphene samples. This opens the way to a fully compatible integration of graphene with SiC devices on the wafers that constitute the standard in today's SiC industry.Comment: 11 pages, 4 figures , Submitted in AP
