A THEORETICAL AND EMPIRICAL INVESTIGATION OF THE SUPPLY RESPONSE IN THE U.S. BEEF-CATTLE INDUSTRY AgEcon
Aadland, David; Bailey, DeeVon; Feng, Shelly.
This paper investigates the response of beef cattle producers to changes in the price of cattle. Previous research has suggested that there may be a negative short-run supply response to a permanent increase in the price of cattle. We build a dynamic, rational expectations model that predicts that the supply response is generally positive, even for permanent shocks in the short run, and nests the negative supply response as a special case for appropriately restricted demand shocks. Using annual US time series data (1930-1997) and a simultaneous-equations econometric approach, we find a positive short-run supply response in the cow market and mixed evidence in the heifer market.

Environments of the Black-chinned Tilapia, Sarotherodon Melanotheron, and Their Potential Effects on the Genetic Structure of Stocks in Ghana OceanDocs
Abban, E.K.; Asante, A.K.; Falk, T.M..
Ghana is one of the countries bordering theAtlantic Ocean on the coast of Africa. The country is located between latitudes 5" N and11" N and longitudes 1" E and 3" W Thecoastline of Ghana, approximately 550 kmlong, is dotted with about 50 lagoons andestuaries that, together with rocky capes and avariety of sandy bays, constitute its coastalwetlands (Armah 1993). These lagoons,estuaries and associated floodplains providehabitats for a variety of wildlife including birdsand fishes (Ntiamoa-Baidu 1991). With an estimated 40 000 ha surface area, the lagoonsare important fish and fisheries resources forassociated communities. The fish speciescomposition of these lagoons varies slightly,but a constant and predominant species is theblack-chinned tilapia,...

West African fish biodiversity reference center: Ghana OceanDocs
Abban, E.K.; Teugels, G.G.; Fermon, V..
Renewable natural resources constitute major sources for socioeconomic development of all developing countries, if they can be con-served, developed and sustainably exploited. For its strategic conservation and sustainable exploitation, biodiversity has to be investigated and documented at various levels and in an internationally accepted manner. However, the human and material resources available in the developing countries are insufficient to under-take the necessary studies, while various forces continue to degrade or erode biodiversity; The obvious solution is through collaboration in research and training.

La violence, l'Etat et l'ethnicité dans la Corne de l'Afrique : au niveau local et mondial IRD
Abbink, J..
Cet article se penche sur les relations changeantes entre la société locale et l'Etat dans la Corne de l'Afrique. L'impact du processus de mondialisation politique et économique qui se répercute également, inexorablement, sur les sociétés africaines transforme les conceptions et l'usage qui est fait de l'ethnicité, de l'identité de groupe et de la violence. On tente de distinguer trois niveaux d'interaction entre le niveau local et celui de l'Etat. Pour traiter du premier niveau, on décrit les évolutions qui se sont produites au sein d'une société agropastorale du sud de l'Ethiopie, les Suris, exemple typique d'une société locale transformée par la mondialisation. On s'aperçoit qu'à cause de leur insertion dans des interactions plus larges au niveau...

TARIFF RATE QUOTA IMPLEMENTATION AND ADMINISTRATION BY DEVELOPING COUNTRIES AgEcon
Abbott, Philip C.; Morse, B. Adair.
Tariff rate quota administration and implementation are empirically evaluated for the fourteen developing countries notifying the WTO of the use of TRQs. FAO trade data, UNCTAD data on applied tariffs and the WTO notifications permit us to assess underfill of quotas, discrimination among exporters, use of state trading as an implementation mechanism, and the extent of protection under these TRQs. Substantial liberalization was found, generally due to use of low MFN tariffs rather than through TRQs permitting greater market access. High tariff bindings and endogenous quotas allow these countries to pursue flexible trade regimes within their WTO commitments.

How increasing availabilities of carbon and nitrogen affect atrazine behaviour in soils Inra
Abdelhafid, R.; Houot, S.; Barriuso, E..
The effect of increasing amounts of glucose and mineral N on the behaviour of atrazine was studied in two soils. One had been exposed to atrazine under field conditions (adapted soil), the other had not (non-adapted soil), resulting, respectively, in an accelerated degradation of atrazine in the adapted soil and in a slow degradation of the herbicide in the non-adapted soil. The dissipation of 14C-atrazine via degradation and formation of non-extractable "bound" residues was followed during laboratory incubations in soils supplemented or not with increasing amounts of glucose and mineral N. In both soils, glucose added at rates of up to 16 g C kg–1 soil did not modify atrazine mineralization but increased the formation of bound residues; this was probably...

Topografia das artérias e veias hilares em rins de cão (Canis familiaris, L. 1758) da raça Pequinês Braz. J. Vet. Res. Anim. Sci.
ABDO,Maria das Graças Gomes Sandin; PEDUTI NETO,José; SOUZA,Wilson Machado de; MIGLINO,Maria Angélica.
Em 30 pares de rins estudaram-se as artérias e veias, no hilo de cão da raça Pequinês. Os ramos arteriais são contados à direita e à esquerda, entre 6 e 16, e 5 e 13, e as raízes venosas, 1 e 7, e 1 e 10; os vasos arteriais são exclusivamente periféricos 100% e 93,3%, e as raízes venosas centrais; os vasos arteriais são iguais em número, 13,3%, e as raízes venosas, 46,6%; os quadrantes craniais são mais densamente povoados. O teste t de Student não é significante, ao nível de 5%, quanto ao sexo e aos rins (direito e esquerdo). O coeficiente de correlação linear de Pearson é positivo entre o número de artérias e veias, nas fêmeas, para ambos os rins, mas inexistente nas mesmas condições entre os machos.

Borrelia sp. in naturally infected Didelphis aurita (Wied, 1826) (marsupialia: didelphidae) BABT
Abel,Isis dos Santos; Almeida Junior,Denclair Escobar de; Fonseca,Adivaldo Henrique da; Soares,Cleber Oliveira; Ishikawa,Márcia Mayumi.
Fifty-six opossums (Didelphis aurita) were captured on the campus of Universidade Federal Rural do Rio de Janeiro, Seropédica county, Rio de Janeiro state, in order to investigate the occurrence of Borrelia sp among them in relation with the study of spirochaetemia and its ectoparasites. Blood tests were made through dark field and phase contrast microscopy, as well as the obtainment of blood smears. Smears were stained with Giemsa stain, which did not prove efficacy. There was no relation between results obtained through blood tests (13 opossum positive for Borreliasp.), and this technique (two positive animals). Parasitaemia studies of 37 animals kept in captivity as well as of several recaptures in which animals once negative proved to be positive days...

L'éducation pour la santé et l'assainissement dans la lutte contre la bilharziose IRD
Aboubacar, A..
L'éducation pour la santé a été une composante importante du programme de lutte contre la bilharziose urinaire au Niger dès son démarrage. L'objectif était de faire percevoir le rôle de la population dans le maintien de la schistosomose au sein des périmètres irrigués. L'éducation pour la santé était étroitement associée à l'assainissement et à l'approvisionnement en eau potable. L'ensemble s'inscrivait dans le cadre de la participation communautaire aux soins de santé primaire. Les difficultés rencontrées sont décrites et expliquent en grande partie la médiocrité des résultats dans ce domaine. (Résumé d'auteur)

Le projet de lutte contre la bilharziose urinaire dans la vallée du fleuve Niger IRD
Aboubacar, A.; Garba, A..
Le programme de lutte contre la bilharziose urinaire au Niger a été initié en 1980 pour réduire la morbidité de la bilharziose urinaire dans la zone de périmètres irrigués de la vallée du fleuve Niger où des rizières avaient été aménagées. Quatre stratégies ont été utilisées : traitement des populations par le praziquantel, éducation pour la santé, formation et assainissement du milieu. Plus de 110 000 personnes réparties dans 171 villages étaient concernées par ce projet. Le projet a été progressivement décentralisé pour être intégré aux structures nationales de santé. Parallèlement, une recherche opérationnelle a permis de définir des indicateurs de prévalence et de morbidité tant pour l'évaluation de l'endémie avant intervention et la définition des...

Condutividade elétrica, reação do solo e acidez potencial em solos adubados com composto de lixo Rev. Bras. Ciênc. Solo
Abreu Junior,C. H.; Muraoka,T.; Lavorante,A. F.; V.,F. C. Alvarez.
Foram estudados os efeitos da aplicação do composto de lixo, proveniente da cidade de São Paulo (usina de compostagem São Matheus), na presença e ausência de calcário dolomítico (para elevar a saturação por bases a 70%) e de adubos minerais, sobre a condutividade elétrica (CE), pH em CaCl2 0,01 mol L-1 e em água, e acidez potencial (H + Al) de 21 solos ácidos e cinco solos alcalinos, nos quais o calcário foi substituído por gesso. O experimento foi realizado em condições de casa de vegetação em delineamento em blocos ao acaso, com parcelas em faixas e três repetições. Foi verificado que a aplicação do composto de lixo promoveu o aumento da CE dos solos. Todavia, esse efeito foi inferior àquele causado pelos adubos minerais. Os maiores valores de CE (> 2...
