A Composite Run-to-the-Bank Rule for Multi-Issue Allocation Situations

In this paper, we propose a new extension of the run-to-the-bank rule for bankruptcy situations to the class of multi-issue allocation situations.We show that this rule always yields a core element and that it satisfies self-duality. We characterise our rule by means of a new consistency property, issue-consistency.allocation;bankruptcy;cooperative games;consistency

An eclectic third generation model of financial and exchange rate crises

This paper presents an eclectic model that systematizes the dynamics of self-fulfilling crises, using the main aspects of the three typologies of third generation models, to describe the stylized facts that hasten the withdrawal of a pegged exchange rate system. The most striking contributions are the implications for economic policy as well the vanishing role of exchange rate as an instrument of macroeconomic adjustment, when balance-sheet effects are a real possibility.speculative attack, financial liberalization, financial panic, financial and exchange rate crisis

The Neighbor-Locating-Chromatic Number of Pseudotrees

A $k$-coloring of a graph $G$ is a partition of the set of vertices of $G$ into $k$ independent sets, which are called colors. A $k$-coloring is neighbor-locating if any two vertices belonging to the same color can be distinguished from each other by the colors of their respective neighbors. The neighbor-locating chromatic number $\chi _{_{NL}}(G)$ is the minimum cardinality of a neighbor-locating coloring of $G$. In this paper, we determine the neighbor-locating chromatic number of paths, cycles, fans, and wheels. Moreover, a procedure to construct a neighbor-locating coloring of minimum cardinality for these families of graphs is given. We also obtain tight upper bounds on the order of trees and unicyclic graphs in terms of the neighbor-locating chromatic number. Further partial results for trees are also established.Comment: 18 pages, 8 figure

Influence of operational parameters on characteristics of pneumatic hammers

The paper covers the results of experimental study in influence of temperature and compressed air pressure, pressing force on operational characteristics of puncher. It is shown that increasing the temperature of compressed air the less the initial degree of compression in the back chamber, the more the energy parameters are, but air consumption decreases unequally for different types of puncher. It is stated that increasing the pressing force the air consumption grows up to a definite limit which is the most significant factor in the case of plugger with spring-loaded valve

Cocoa Yield Development of Different Sites, Varieties, Production Systems and Years, in Alto Beni, Bolivia

One of the most essential limiting factors of cocoa (Theobroma cacao L.) productivity worldwide is pests and diseases. Each of the major production regions has its specific pests and diseases. Reported yield losses range from minor to almost 100 per cent. In Alto Beni, located in the Amazonian watershed of the department La Paz, Bolivia, the Research Institute of Organic Agriculture (FiBL) and its local partners are addressing several problems of cocoa producers using a participatory technology development approach. Problems were identified in a participatory way and are, in order of priority, i) to reduce the incidence of pests and diseases, mainly the cocoa mirid (Monalonion dissimulatum) and Frosty Pod Rot (Moniliophthora roreri); ii) to evaluate the productivity of different cocoa varieties (local selections, introduced clones), and iii) to document the management practices and plantation layouts of high yielding cocoa farmers. In order to develop novel biological pest control measures, both the knowledge of cocoa yield development in the course of the harvest period, as well as the dynamics of pests and diseases are of great interest. Data from three different research activities of the mentioned project are analysed for yield development, the appearance, and the incidence of pests and diseases, where available. The research data are from: a) On-farm trials in multiple locations which were established in 2004. The performance of 16 cocoa varieties has been assessed for 3 years (2010–2012). b) Four high yielding cocoa farmers’ fields (2012 only). c) A long-term field experiment assessing the sustainability of five cocoa production systems (2011 and 2012). The trial investigates the influence of monocultures and different agroforestry systems under organic and conventional management on the yield development, among other agronomic, economic and environmental parameters

Contribución de las entidades de “Economía Social” a la gestión eficiente del agua para uso agrícola: situación en la Región de Murcia

En la literatura abundan los trabajos dirigidos a caracterizar las entidades que integran la “Economía Social” en España y a cuantificar su contribución a los diferentes sectores económicos y, en especial, al sector agroalimentario. Sin embargo, estos trabajos no se han hecho eco de la importancia de estas organizaciones para la gestión de un recurso tan fundamental para el sector agrario como el agua, y del papel que en ella juegan las Comunidades de Regantes (CCRR), sobre todo, junto a las entidades asociativas agrarias (Cooperativas Agrarias y Sociedades Agrarias de Transformación). Aunque apenas contempladas como entidades de “Economía Social” en los estudios publicados sobre este tipo de organizaciones, a las Comunidades de Regantes (CCRR) corresponde la función prioritaria de distribuir y administrar de una manera eficiente las aguas asignadas entre sus miembros. A ello, también pueden contribuir otras organizaciones ampliamente reconocidas dentro de la “Economía Social” como es el caso de las Cooperativas Agrarias y las Sociedades Agrarias de Transformación. En este contexto, el objetivo de este trabajo es, de un lado, poner de relieve que las CCRR comparten los principios de las empresas de “Economía Social”, y resaltar sus características con relación a las Cooperativas Agrarias y SAT. Por otra parte, se identifican los componentes de la eficiencia en la gestión del agua para uso agrícola y se analiza la contribución que las CCRR y las entidades asociativas agrarias de la Región de Murcia realizan a la mejora de la misma a través de los diversos servicios que prestan a sus socios (formación, información, asesoramiento, financiación, etc).In the literature there are many works directed at characterizing those entities which form the “Social Economy” in Spain and at quantifying their contribution to the different economic sectors, especially the agricultural food sector. However, these works have not reflected the importance of these organizations for the management of a resource as fundamental for the agricultural sector as is water, and of the role of the agrarian associative entities (Agricultural Cooperatives and Agricultural Transformation Societies) and, above all, the Irrigation Communities (CCRR). Although scarcely mentioned as entities of “Social Economy” in the studies on this type of organizations, the Irrigation Communities have the priority function of efficiently distributing and administering the water assigned amongst their members. To that, other organizations widely recognised within the “Social Economy” can also make a contribution, as is the case with the Agricultural Cooperatives and Agricultural Transformation Societies (SAT). In this context, the objective of this paper is, on the one hand, to highlight that the CCRR share the principles of the “Social Economy” companies, and to underline their characteristics with regard to the Agricultural Cooperatives and SAT. On the other hand, the components of the efficiency in the management of water for agricultural use are identified and the contribution that the CCRR and the agrarian associative entities of the Region of Murcia make to improve them is analyzed
