Nuclear-follower foraging associations among Characiformes fishes and Potamotrygonidae rays in clean waters environments of Teles Pires and Xingu rivers basins, Midwest Brazil

Por meio de observações sub e supra-aquáticas foram registradas associações alimentares do tipo nuclear-seguidor entre três espécies de peixes characiformes - Chalceus epakros, Hemiodus semitaeniatus e Hemiodus unimaculatus - e uma espécie de raia de água doce - Potamotrygon orbignyi - nas bacias dos rios Teles Pires e Xingu, no Centro-Oeste do Brasil. Os peixes teleósteos foram observados seguindo as raias quando estas revolviam o substrato à procura de invertebrados, formando discretas nuvens de sedimento. Essas situações atraíram os peixes que se aproximaram das raias para se alimentar de pequenas presas e outros tipos de alimentos expostos desta forma. Esse é um típico exemplo de relação comensal onde um participante é beneficiado enquanto o outro não é prejudicado e representa o segundo registro na literatura de associação alimentar do tipo nuclear-seguidor entre raias potamotrigonídeas e peixes teleósteos, demonstrando o potencial de estudos naturalísticos para a descoberta de novas interações envolvendo espécies de peixes de água doce.

Avian flu: the creation of expectations in the interplay between science and the media

This paper examines the emerging cultural patterns and interpretative repertoires in reports of an impending pandemic of avian flu in the UK mass media and scientific journals at the beginning of 2005, paying particular attention to metaphors, pragmatic markers ('risk signals'), symbolic dates and scare statistics used by scientists and the media to create expectations and elicit actions. This study complements other work on the metaphorical framing of infectious disease, such as foot and mouth disease and SARS, tries to link it to developments in the sociology of expectations and applies insights from pragmatics both to the sociology of metaphor and the sociology of expectations.

La presupuestación como herramienta de planificación y control de los recursos financieros y su aplicación estratégica en Almacenes Leader S.A. de C.V.distribuidora de electrodómesticos de San Salvador.

La elaboración del presente trabajo de investigación consiste en hacer uso de la presupuestación como herramienta de planificación y control de los recursos financieros de una empresa distribuidora de electrodomésticos de San Salvador, denominada Almacenes Leader S.A. de C.V. ya que en la actualidad esta herramienta brinda beneficios de carácter económicos, tales como aumentar la utilidad y disminuir los excesos de asignación de recursos financieros en áreas improductivas contribuyendo con la administración de la misma, además brindan apoyo para el cumplimiento de las diferentes operaciones permitiendo con esto que se logren los objetivos planteados. Así mismo los presupuestos contribuyen a mantener una liquidez financiera estable, por lo que se realizó un diagnóstico en la empresa con el objeto de conocer la forma de administrar los recursos financieros, dicho diagnóstico se llevó a cabo utilizando el método científico ya que éste, por ser un proceso sistemático, permite abordar el problema, recopilando, analizando y aplicando dicha información. A la vez se hace uso de la observación directa, la entrevista realizada a los propietarios de la empresa y la encuesta dirigida al personal del área contable y los jefes de tienda, en donde se encontró que dicha empresa no utiliza la presupuestación como herramienta de planificación y control de los recursos financieros, para lo cual se ha elaborado una propuesta de la aplicación e implementación de algunos de los presupuesto que sean apropiados al tipo de empresa. Para elaborar de dichos presupuestos se tomó en cuenta los datos históricos, la información obtenida de la entrevista y de la encuesta, también se hizo uso de algunos supuestos que permitieron elaborar los presupuesto, ya que no se tuvo acceso a toda la información necesaria por parte del Contador General. Se propone de igual manera un plan de implementación y control que permita conocer cómo se van a desarrollar los presupuestos, determinando si se está cumpliendo lo proyecto en comparación a los datos reales que se irán obteniendo. Por otro lado, se realizó un análisis financiero de dos años anteriores al actual, utilizando algunas de las razones financieras que brindan información sobre la situación financiera, aportando datos sobre la liquidez, rentabilidad, administración de activos y el nivel de deuda de la empresa, que contribuyan a tomar decisiones financieras y adaptarlas a los presupuestos para obtener mejores resultados. Es por ello que se concluye que: Almacenes Leader, no utilizan la presupuestación como herramienta de planificación y control de los recursos financieros, debido a que la determinación de sus operaciones se elaboran con base a la experiencia de los propietarios y el comportamiento del mercado, así mismo no hace uso de las razones financieras, lo que impide que se conozcan aspectos financieros importantes y por ende tomar buenas decisiones, que determinen el rumbo a seguir.

Programas de desarrollo rural en la Unión Europea: La iniciativa comunitaria LEADER

Introducción La puesta en marcha de una política de desarrollo rural por parte de la Unión Europea fue, en buena medida, la consecuencia de la coincidencia,  a finales de la década de los ochenta, de dos factores. Por un lado, la crisis de la Política Agraria Común (PAC) “clásica” y la necesidad de reorientar las medidas y recursos financieros de la misma, lo que llevó a prestar una creciente atención al “mundo rural”, en detrimento de la “modernización agraria” y, por lo tanto, a “ruralizar” una parte del PAC. De otro lado, la creciente atención ´prestada a la llamada “cohecion económica y social” en un momento en que la Unión se había ampliado (España y Portugal entraron en 1986), la integración se estaba reforzando (el “mercado único”para 1992) y se estaba en vísperas de la unificación monetaria. En este contexto, los territorios rurales debían ser objeto de atención, pues muchos de ellos continuaban perdiendo población y presentaban estructuras productivas poco diversificadas.

Topic extraction from microblog posts using conversation structures

Conventional topic models are ineffective for topic extraction from microblog messages since the lack of structure and context among the posts renders poor message-level word co-occurrence patterns. In this work, we organize microblog posts as conversation trees based on reposting and replying relations, which enrich context information to alleviate data sparseness. Our model generates words according to topic dependencies derived from the conversation structures. In specific, we differentiate messages as leader messages, which initiate key aspects of previously focused topics or shift the focus to different topics, and follower messages that do not introduce any new information but simply echo topics from the messages that they repost or reply. Our model captures the different extents that leader and follower messages may contain the key topical words, thus further enhances the quality of the induced topics. The results of thorough experiments demonstrate the effectiveness of our proposed model.

Enhancing legume ecosystem services through an understanding of plant–pollinator interplay

Legumes are bee-pollinated, but to a different extent. The importance of the plant– pollinator interplay (PPI), in flowering crops such as legumes lies in a combination of the importance of pollination for the production service and breeding strategies, plus the increasing urgency in mitigating the decline of pollinators through the development and implementation of conservation measures. To realize the full potential of the PPI, a multidisciplinary approach is required. This article assembles an international team of genebank managers, geneticists, plant breeders, experts on environmental governance and agro-ecology, and comprises several sections. The contributions in these sections outline both the state of the art of knowledge in the field and the novel aspects under development, and encompass a range of reviews, opinions and perspectives. The first three sections explore the role of PPI in legume breeding strategies. PPI based approaches to crop improvement can make it possible to adapt and re-design breeding strategies to meet both goals of: (1) optimal productivity, based on an efficient use of pollinators, and (2) biodiversity conservation. The next section deals with entomological aspects and focuses on the protection of the “pest control service” and pollinators in legume crops. The final section addresses general approaches to encourage the synergybetweenfoodproductionandpollinationservicesatfarmerfieldlevel.Twobasic approaches are proposed: (a) Farming with Alternative Pollinators and (b) Crop Design System.

Sustainable initiatives focused on social responsibility and regional development: a study of the leader of the petrochemical industry

The present work will investigate the issue of environmental responsibility actions in the ABC Paulista region, of a leading company in the petrochemical sector. In this context, the problem has been to see how the leading company in the domestic petrochemical industry conducts itself relative to the concept of sustainability and what the consequences of these initiatives in the ABC Paulista are. Thus, the objectives are to identify these consequences and practices with regard to regional development in areas where the leader of the national petrochemical company has significant performance, with highlights on economic, social and environmental impacts. The present investigation is justified by the fact that the company is among the world leaders in the production of biopolymers. The methodology used was qualitative descriptive because this methodological procedure makes it possible to observe and analyze the facts relating to social responsibility initiatives undertaken by the company under study without manipulating them , in establishing correlations on perception of other stakeholders before the actions addressed in this research. Therefore, the results obtained indicate that environmental responsibility initiatives taken by the company satisfy the paradigm of Sustainability and Social Responsibility, in the promotion of regional development in its geographic area.

Apprendre à être un Leader dans un Programme de Leadership: Perceptions, Éxpérience Préalable en Leadership et Sexe de l’Étudiant

The purpose of this study was to examine whether leadership can be learned through the Community Recreation and Leadership Training (CRLT) program and how effective the program is in terms of changing the perceptions and abilities of the students. The intentions of the researcher were to discover crucial learning moments as perceived by students and to gain insights that could lead to future improvements to enhance and enrich learning in a leadership program. To continue to be a viable program and to keep step with the demands of the recreation/leisure industry and society's wide-ranging needs, this study may help to inform the program's 'action plan' for continued success. This study employed a mixed method approach to determine how college students develop effective leadership ability in a three-year Community Recreation and Leadership Training (CRLT) college career program. First, a number of statistical tests were carried out to examine the four research questions used to guide the study. The SPSS software was used to analyze the data collected. The first research question asked how perceptions of leadership change as a result of being in a three-year leadership program. This study, using the Student Leadership Practice Inventory (SLPI), compared the five SLPI leadership dimensions by year. The SLPI was administered to all the first, second, and third year CRLT students ( N = 84). A one-way analysis of variance in participants' scores was conducted. No significant differences were revealed in any of the five dimensions of the SLPI among the first, second, and third year students at p < .05. However, two dimensions (model and encourage) approached significance and may hint at a possible influence the program is having on its students as they progress into the third year. The second research question asked whether perceptions of leadership vary by gender. Comparing the mean scores between the males and females on the five dimensions of the SLPI, no significant differences were found. The third research question asked whether prior leadership experience results in better academic performance for CRLT students in their 1st term. A one-way analysis of variance was conducted to evaluate the relationship between prior leadership experience and mean scores on academic performance. No significant correlations were found between grades and low, medium, or high levels of prior leadership experience F(2,79) = 2.67, p = .08. A correlation coefficient was also computed to determine whether there was a relationship between the Recreation Leadership I course grade and prior leadership experience. The correlation coefficient (.02) was statistically significant, r(80) = .24, p < .05. However, further studies with a larger sample size would be necessary to help determine this. The fourth question asked whether there was a correlation between students' first semester grades and their scores on the Student Leadership Practice Inventory (SLPI). Bivariate correlations (Pearson) were computed for the five SLPI dimensions with academic performance. None of the correlations using the five SLPI indicators was significant. Qualitative data was examined to discover what factors and experiences help students to assert a more effective leadership role. The study relied on content analysis of personal statements, and focus groups. Student perceptions of an effective leader, students' perceptions of their own abilities, and the strengths of the program were explored. A content analysis of the 'Personal Statements' was carried out to determine how students defined leadership prior to their having had any formal teaching in a college program. The result of the analysis of personal statements provided eight leadership categories used as an initial baseline for the study. Six focus groups (totaling N = 30) were conducted. Students responded to four key questions: how they define leadership. What is the single most effective quality of a leader? What leadership skills did they feel they had gained? How had the program helped them obtain their skills? Students credited the CRLT program with helping them develop a variety of leadership skills. Students revealed that they had gained skills such as confidence, knowledge and understanding of people's needs, and becoming more self-directed. They attributed their skill development to such things as good course design, intensive outdoor education and fieldwork courses, "hands on" learning approaches, group work, skill practice, the support they received from teachers, and encouragement they were given by their peers. A common finding among genders was defining an effective leader as someone who is "confident". However, the definition of the most important quality of a leader varied by gender. While males showed a tendency to prefer a leader being "confident," females preferred a leader being a "teacher".

A finite element framework for the interplay between delamination and buckling of rubber-like bi-material systems and stretchable electronics

In this study, a finite element (FE) framework for the analysis of the interplay between buckling and delamination of thin layers bonded to soft substrates is proposed. The current framework incorporates the following modeling features: (i) geometrically nonlinear solid shell elements, (ii) geometrically nonlinear cohesive interface elements, and (iii) hyperelastic material constitutive response for the bodies that compose the system. A fully implicit Newton–Raphson solution strategy is adopted to deal with the complex simultaneous presence of geometrical and material nonlinearities through the derivation of the consistent FE formulation. Applications to a rubber-like bi-material system under finite bending and to patterned stiff islands resting on soft substrate for stretchable solar cells subjected to tensile loading are proposed. The results obtained are in good agreement with benchmark results available in the literature, confirming the accuracy and the capabilities of the proposed numerical method for the analysis of complex three-dimensional fracture mechanics problems under finite deformations.
