Eksistensi Jaminan dalam Kontrak Pengadaan Gabah/ Beras pada Perum Bulog Divisi Regional Yogyakarta

The binding of security in rice sales contract between Perum BULOG Yogyakarta Regional Division and contractors is carried out in a pawning manner (for money and periodical deposit used as the security), and personal security (for bank guaranty. The forms of default include supplying rice trim mill rice that is below the standard, overdue provision, short amount of supply, and supplying rice not from the product of rice mill agreed on in the contract. Some efforts to solve these problems include giving an addendum (grace period), obligation for compensation payment of 111000 to a maximum of 0,5% of the total shortage, and internal resolution. Thefactors preventing any claim for the security are : almost 80% of contractors can use the grace period offered, and the compensation payment is able to compensate the loss suffered by Perum BULOG. One of the reasons from theoritical bases is that the risk in a sales contract for measured and calculated commodity must be born by the buyer, which is Perum BULOG Yogyakarta Regional Division in this case.

Movimientos sociales insurreccionales en África occidental: una mirada retrospectiva a la rebelión armada en Costa de Marfil de 2002 a 2011

A retrospective analysis is made of the armed rebellion that took place in Ivory Coast between 2002 and 2011 as one of the most important insurrectionary social movements of West Africa in the first decade of the 21st century. It is assumed that French neocolonialism influenced this social movement through co-option to strengthen its regional influence, which was threatened by the actions of the current government in Ivory Coast. From an analytic-synthetic perspective supported on critical points that stand out for the discussion, it is concluded that despite anchoring its claim in the Ivorian identity crisis, the social movement at issue drifted from its aspiration of identity social change, to the interest in political power, for having been co-opted to secure external interests, for which the sharpened Ivorian problem was poorly managed and resolved.Se hace un análisis retrospectivo a la rebelión armada acontecida en Costa de Marfil entre 2002 y 2011 como uno de los movimientos sociales insurreccionales más importantes de África occidental de la primera década del siglo xxi. Se parte de que el necolonialismo francés incidió en dicho movimiento social, a través de la cooptación para afianzar su influencia regional, amenazada por las acciones del gobierno de turno en Costa de Marfil. A partir de una perspectiva analítico-sintética, sustentada en puntos críticos que resaltan para la discusión, se concluye que, a pesar de anclar su reivindicación en la crisis identitaria marfileña, el movimiento social en cuestión se desvió de su pretensión de cambio social identitario por el interés por el poder político, por haber sido cooptado para asegurar intereses externos para los cuales, el problema marfileño agudizado, fue mal gestionado y resuelto

Les pratiques de contrôle de gestion des coopératives ivoiriennes : une recherche empirique dans la ville de DALOA

Cette étude vise l’identification des déterminants de l’adoption des systèmes de contrôle de gestion dans les coopératives ivoiriennes. Elle analyse tout particulièrement les facteurs de contingence susceptibles d’influencer significativement les pratiques de contrôle de gestion des coopératives ivoiriennes. Pour ce faire, nous avons eu recours à une enquête quantitative. L’échantillon est constitué de 100 coopératives de la ville de Daloa déterminées par la méthode aléatoire simple. Les méthodes d’analyse sont constituées des statistiques descriptives, les tests statistiques, le modèle du logit multinomial. Les résultats révèlent que les facteurs de contingence à savoir la taille, le secteur d’activité, le niveau de formation du dirigeant et le type de formation du dirigeant influencent les pratiques de contrôle de gestion des coopératives ivoiriennes. En outre, ces résultats mettent en exergue des pratiques de contrôle de gestion différenciées à savoir des pratiques de contrôle de gestion peu développées et des pratiques de contrôle de gestion développées

Les résultats révèlent que les pratiques de contrôle de gestion des coopératives renferment la comptabilité générale, le rapport annuel de gestion, le calcul du coût direct, le budget de trésorerie et le plan de campagne agricole. En outre, les facteurs explicatifs des pratiques de contrôle de gestion sont: la taille de la coopérative, le secteur d’activité de la coopérative, le niveau de formation du président de la coopérative. L’intérêt de notre étude est de proposer les méthodes et outils de contrôle de gestion des coopératives ivoiriennes. &nbsp

Numerical and experimental investigation on shot-peening induced deformation. Application to sheet metal forming

ABSTRACT The peen forming process is commonly used in the aeronautical industry to form large wing skin panels. This process presents many advantages in terms of cost, production time, and beneficial induced residual stresses. Setting the accurate process parameters to form a given pattern requires however a certain experience and sometimes many trials and errors. The authors propose to model the shot peening induced deformations by elastically equilibrating the real plastic strain gradient present in the whole structure. A complete numerical and experimental protocol is proposed to determine the plastic strain gradient assuming the knowledge of some experimental data. The proposed approach consists in determining the plastic strain field by inverse calculation based on experimentally measured residual stresses fields. A second approach is based on the inverse calculation of shot peening induced plastic strains knowing the global deformation of the treated sheet. A comparison between the proposed approaches applied to partially treated sheets is presented along with experimental data. The numerical results are in good agreement with experimental data and show the strong influence of the peening path on the resulting global deformations of the treated samples

Detection of Prion Protein Particles in Blood Plasma of Scrapie Infected Sheep

Prion diseases are transmissible neurodegenerative diseases affecting humans and animals. The agent of the disease is the prion consisting mainly, if not solely, of a misfolded and aggregated isoform of the host-encoded prion protein (PrP). Transmission of prions can occur naturally but also accidentally, e.g. by blood transfusion, which has raised serious concerns about blood product safety and emphasized the need for a reliable diagnostic test. In this report we present a method based on surface-FIDA (fluorescence intensity distribution analysis), that exploits the high state of molecular aggregation of PrP as an unequivocal diagnostic marker of the disease, and show that it can detect infection in blood. To prepare PrP aggregates from blood plasma we introduced a detergent and lipase treatment to separate PrP from blood lipophilic components. Prion protein aggregates were subsequently precipitated by phosphotungstic acid, immobilized on a glass surface by covalently bound capture antibodies, and finally labeled with fluorescent antibody probes. Individual PrP aggregates were visualized by laser scanning microscopy where signal intensity was proportional to aggregate size. After signal processing to remove the background from low fluorescence particles, fluorescence intensities of all remaining PrP particles were summed. We detected PrP aggregates in plasma samples from six out of ten scrapie-positive sheep with no false positives from uninfected sheep. Applying simultaneous intensity and size discrimination, ten out of ten samples from scrapie sheep could be differentiated from uninfected sheep. The implications for ante mortem diagnosis of prion diseases are discussed

Construir sociedades justas, pacíficas e inclusivas a partir das identidades nacionais. Uma contribuição para a Agenda 2030

A reflection is made on the relevance of national identity as a suitable methodological path for the construction of fair, peaceful and inclusive societies proposed by the 2030 Agenda in its sixteenth goal. Peace, justice and inclusion are cardinal values that take more of an intersubjective dimension rather than a legal one. Their attainment could be achieved in a sustained way from an essentially intersubjective perspective, through which national identity, as a collective identity can be assumed as an ideal channel. A brief state of the art of the sixteenth goal in the Agenda is made to highlight its particular relevance and identify the contribution of national identity as an efficient methodological path for its realization. Afterward, a theoreticalconceptual approach of national identity is established to emphasize the strength of the feeling that it produces from two models of nation, and to emphasize its value for the construction of fair, peaceful and inclusive societies.Se reflexiona en torno a la relevancia de la identidad nacional como ruta metodológica adecuada para la construcción de sociedades justas, pacíficas e inclusivas propuesta por la Agenda 2030 en su objetivo dieciséis. La paz, justicia e inclusión constituyen valores cardinales que asumen una dimensión más intersubjetiva que jurídica. Su concreción podría lograrse de forma sostenida desde una perspectiva esencialmente intersubjetiva a través de la cual la identidad nacional en cuanto identidad colectiva puede asumirse como canal expedito. Se hace un breve estado de la cuestión del objetivo dieciséis de la Agenda para resaltar su relevancia particular e identificar la contribución de la identidad nacional como ruta metodológica eficiente para su realización. Luego, se establece un acercamiento eórico-conceptual de la identidad nacional para recalcar la fuerza del sentimiento que genera a partir de dos modelos de nación, y enfatizar su valor para la construcción de sociedades justas, pacíficas e inclusivas.É feita uma reflexão sobre a relevância da identidade nacional como caminho metodológico adequado para a construção de sociedades justas, pacíficas e inclusivas propostas pela Agenda 2030 em suas dezesseis meta.

Sua realização poderia ser alcançada de forma sustentada a partir de uma perspectiva essencialmente intersubjetiva por meio da qual a identidade nacional como uma identidade coletiva pode ser assumida como um canal expedito. Um breve estado da arte do objetivo dezesseis da Agenda é feito para destacar sua particular relevância e identificar a contribuição da identidade nacional como um caminho metodológico eficiente para sua realização.

Construcción identitaria en África. Un análisis desde los estudios de identidad, poder y agencia

This article analyzes the reality of identity construction in Africa starting from some contributions of identity studies. It is stated that the African identity has been influenced by European colonialism, which imposed profound structural and functional changes in that continent in the political, social, ideological and cultural. In its central structure, the work discusses some contributions about identity, including those of Geertz, Barth and Gimenez; and, in light of these contributions, the identity construction in Africa is analyzed diachronically.Este artículo analiza la realidad de la construcción identitaria en África a partir de algunas de las contribuciones de los estudios de identidad. Se sostiene que la identidad africana ha sido influida por el colonialismo europeo, mismo que impuso cambios estructurales y funcionales profundos en dicho continente en lo político, social, ideológico y cultural. En su estructura central, el trabajo discute algunas de las contribuciones sobre la identidad, entre ellas, las de Geertz, Barth y Giménez y, a la luz de estas aportaciones, analiza de forma diacrónica la construcción identitaria en África
