Intermediate serial cost-sharing rules

In this paper we give a generalization of the serial cost-sharing rule defined by Moulin and Shenker (1992) for cost sharing problems. According to the serial cost sharing rule, agents with low demands of a good pay cost increments associated with low quantities in the production process of that good. This fact might not always be desirable for those agents, since those cost increments might be higher than others, for example with concave cost functions. In this paper we give a family of cost sharing rules which allocates cost increments in all the possible places in the production process. And we characterize axiomatically each of them by means of an axiomatic characterization related to the one given for the serial cost-sharing rule by Moulin and Shenker (1994).

Aquaculture in tropical Mexican lakes and dams: achievements and perspectives

Mexico, with highly diverse physiography, geology, soils and climate, is a country with a broad mosaic of aquatic ecosystems within 320 watersheds. This paper presents a brief picture of Mexican fresh waters, the distribution of rainfall and the potential for aquaculture. The main fish species and water bodies, dams and lakes, are highlighted. The country faces problems of surface water shortage which requires better management.

Logic-operated mathematical morphology and its optical implementation

A more powerful tool for binary image processing, i.e., logic-operated mathematical morphology (LOMM), is proposed. With LOMM the image and the structuring element (SE) are treated as binary logical variables, and the MULTIPLY between the image and the SE in correlation is replaced with 16 logical operations. A total of 12 LOMM operations are obtained. The optical implementation of LOMM is described. The application of LOMM and its experimental results are also presented.

A common axiom for classical division rules for claims problems

In this paper we introduce a new axiom, denoted claims separability, that is satisfied by several classical division rules defined for claims problems. We characterize axiomatically the entire family of division rules that satisfy this new axiom. In addition, employing claims separability, we characterize the minimal overlap rule, given by O'Neill (1982), Piniles rule and the rules in the TAL-family, introduced by Moreno-Ternero and Villar (2006), which includes the uniform gains rule, the uniform losses rule and the Talmud rule.

The minimal overlap cost sharing rule

In this paper we introduce a new cost sharing rule-the minimal overlap cost sharing rule-which is associated with the minimal overlap rule for claims problems defined by O'Neill (1982). An axiomatic characterization is given by employing a unique axiom: demand separability. Variations of this axiom enable the serial cost sharing rule (Moulin and Shenker, 1992) and the rules of a family (Albizuri, 2010) that generalize the serial cost sharing rule to be characterized. Finally, a family that includes the minimal overlap cost sharing rule is defined and obtained by means of an axiomatic characterization.

A potential approach to claims problems

Hart and Mas Colell (1989) introduce the potential function for cooperative TU games. In this paper, we extend this approach to claims problems, also known as bankruptcy or rationing problems. We show that for appropriate subproblems, the random arrival rule, the rules in the TAL-family (which include the uniform gains rule, the uniform losses rule and the Talmud rule), the minimal overlap rule, and the proportional rule admit a potential. We also study the balanced contributions property for these rules. By means of a potential, we introduce a generalization of the random arrival rule and mixtures of the minimal overlap rule and the uniform losses rule.

Posibles conflictos éticos entre los paradigmas científico-tecnológicos dominantes y la mejora del bienestar de la población en algunas economías emergentes

En los últimos años, algunos países emergentes como China, India y Brasil, han experimentado importantes avances en el área de la innovación científicotecnológica. En este artículo se realiza una primera aproximación a los dilemas éticos que se plantean entre los diversos paradigmas-científico tecnológicos y la mejora del bienestar de la población en estos países. Se evalúan los diversos tipos de conocimiento (patentes y derechos de propiedad intelectual, conocimiento tradicional, innovaciones de base social e innovaciones inclusivas) en función de criterios que tienen que ver con su base local, los objetivos que persiguen y los valores relacionados con esos objetivos. Para los países de renta media y baja, las innovaciones de base social y las innovaciones inclusivas podrían favorecer en mayor medida la mejora del bienestar de sus poblaciones.

Transformaciones en el retablo mayor de San Miguel Arcángel de Lazkao (Gipuzkoa): del Barroco al Neoclasicismo

[ES] El retablo mayor de la localidad guipuzcoana de Lazkao fue realizado por Juan de Ursularre en 1683, siguiendo los parámetros de la retablística barroca. Queriendo engrandecer su aspecto, fue paulatinamente transformado durante el siglo XVIII. Por ello se concibió un nuevo cascarón con pinturas enviadas desde Madrid y más tarde se adecuó a los nuevos gustos neoclásicos mediante una radical reforma realizada en 1791 que consistió en eliminar todo atisbo de decoración barroca.

Arte en Quintana del Pidio (Burgos): estudio histórico-artístico de la iglesia de Santiago Apóstol

La parroquia de Santiago Apóstol de Quintana del Pidio, situada en la ribera burgalesa, se levanta en la plaza mayor de la citada localidad, junto al ayuntamiento. Esta construcción tardogótica de finales de la Edad Media se fue completando con una torre de comienzos del siglo XVI, una portada y una sacristía barrocas y una única capilla dedicada al Santo Cristo, edificada ya en el siglo XVIII. En su interior se conservan cinco retablos barrocos que ejemplifican las fases clasicista, churrigueresca y rococó. También cuenta con pinturas, un interesante ajuar de platería y otros objetos de mobiliario, ornamentos o indumentaria que han sido estudiados en el libro. La metodología histórico-artística empleada en este trabajo permite entender la obra en su contexto, completando su significado con una lectura iconográfica cuando procede. Con la catalogación y la aportación de datos sobre las artes de esta parroquia ribereña se pretenden poner el valor las obras que desde la segunda mitad del siglo XV han ido completando el patrimonio artístico de esta villa para que se adquiera conciencia de su importancia y se dediquen los recursos necesarios para su conservación en el futuro.

Mugilid Fish Are Sentinels of Exposure to Endocrine Disrupting Compounds in Coastal and Estuarine Environments

Effects on fish reproduction can result from a variety of toxicity mechanisms first operating at the molecular level. Notably, the presence in the environment of some compounds termed endocrine disrupting chemicals (EDCs) can cause adverse effects on reproduction by interfering with the endocrine system. In some cases, exposure to EDCs leads to the animal feminization and male fish may develop oocytes in testis (intersex condition). Mugilid fish are well suited sentinel organisms to study the effects of reproductive EDCs in the monitoring of estuarine/marine environments. Up-regulation of aromatases and vitellogenins in males and juveniles and the presence of intersex individuals have been described in a wide array of mullet species worldwide. There is a need to develop new molecular markers to identify early feminization responses and intersex condition in fish populations, studying mechanisms that regulate gonad differentiation under exposure to xenoestrogens. Interestingly, an electrophoresis of gonad RNA, shows a strong expression of 5S rRNA in oocytes, indicating the potential of 5S rRNA and its regulating proteins to become useful molecular makers of oocyte presence in testis. Therefore, the use of these oocyte markers to sex and identify intersex mullets could constitute powerful molecular biomarkers to assess xenoestrogenicity in field conditions.
