Gender, sex and sexuality in two open access communication journals published in Portugal: a critical overview of current discursive practices

The links between gender, sex and sexuality and their relevance are theoretically and politically problematic (Richardson, 2007). One of the difficulties in understanding their interconnections is that these terms are often used differently and ambiguously by different authors (and even by the same authors). This article reports the results of an analysis of the articles published in open access communication journals with known impact factor, edited in Portugal and published between 2005 and 2012. The diverse conceptualisations of those three basic concepts and of their (inter)relationships within communication research are identified. The complexity and the intricate (and often implicit) nature of both the meanings of these categories and their relationships underlie and justify our attention and further research. What the findings suggest about the current communication research into gender issues published in the two journals surveyed is that the ‘Gender differences discourse’ (Sunderland, 2004) is the most pervasive discourse (also) in academic practice. Additionally, they show that gender and sex are mainly taken for a fact, not a question that is worth being studied. The editors of these journals, as well as the scholars submitting manuscripts, need to be more aware of the traditional nature of the theoretical and methodological choices that they make regarding gender- and sex-related issues, as well as of the relative lack of attention to sexuality as a research subject.

Current situation on the occurrence of mycotoxins and toxigenic fungi in Portugal

Mycotoxins are secondary metabolites produced by filamentous fungi that are toxic for humans and animals in small amounts and that are found worldwide in a large number of agricultural commodities. They are usually ingested involuntarily, when contaminated plant products are consumed, and represent a great risk for public health. Therefore, governments throughout the world have imposed strict legal limits for their levels in food and feed products in order to reduce potential health risks for consumers. Despite of its ubiquity, the mycotoxin problem is mainly dependent on regional factors, such as the mycotoxigenic characteristics of the local mycoflora, the local climate conditions, and the local agricultural practices. For this reason, a constant vigilance from local governmental food safety agencies and from the local researcher community is needed. This communication will review the current situation on the occurrence of mycotoxigenic fungi in some Portuguese cultures, such as wine grapes, corn and dried fruits. Particular attention will be given to the incidence of mycotoxigenic Aspergillus strains in those cultures and to the levels of ochratoxin A, aflatoxins, cyclopiazonic acid and fumonisin B2 produced. Data will be discussed taking into account the geographical origin of the isolates and the particular climate conditions of each sampling region. An updated review on the levels of the main mycotoxins found in local products and in imported commodities will also be presented.

An overview of the brewing process

The first chapter of this book has an introductory character, which discusses the basics of brewing. This includes not only the essential ingredients of beer, but also the steps in the process that transforms the raw materials (grains, hops) into fermented and maturated beer. Special attention is given to the processes involving an organized action of enzymes, which convert the polymeric macromolecules present in malt (such as proteins and polysaccharides) into simple sugars and amino acids; making them available/assimilable for the yeast during fermentation.

Towards a pervasive data mining engine: architecture overview

Current data mining engines are difficult to use, requiring optimizations by data mining experts in order to provide optimal results. To solve this problem a new concept was devised, by maintaining the functionality of current data mining tools and adding pervasive characteristics such as invisibility and ubiquity which focus on their users, providing better ease of use and usefulness, by providing autonomous and intelligent data mining processes. This article introduces an architecture to implement a data mining engine, composed by four major components: database; Middleware (control); Middleware (processing); and interface. These components are interlinked but provide independent scaling, allowing for a system that adapts to the user’s needs. A prototype has been developed in order to test the architecture. The results are very promising and showed their functionality and the need for further improvements.

Micro-empresa y capacidad empresarial en Córdoba: situación actual y perspectivas. Microenterprise and entrepreneurship in Córdoba: present situation and perpectives.

Las transformaciones del mercado laboral, tanto de los países desarrollados como en vías de desarrollo, han sido importantes en las últimas décadas. Una de sus manifestaciones es la creciente expansión del trabajo organizado en torno a los micro-emprendimientos. Las investigaciones existentes a nivel internacional indican que la capacidad empresarial que debe poseer el emprendedor es un factor que resulta crucial para el desarrollo y sostenimiento de estas formas de producción. Por tal razón, el estudio de este aspecto y de su relación con los micro-emprendimientos es un tema que está concitando creciente atención y sobre el que existe un cuerpo teórico de literatura específica que ha comenzado a transferirse a los países en vías de desarrollo, donde la discusión es aún incipiente. Los estudios han observado que los micro-emprendimientos están normalmente muy ligados a la familia, esto hace que su desenvolvimiento y evolución resulten afectados por las características particulares de cada hogar. Se trata de un complejo conjunto de situaciones sociales que se generan a partir de estas nuevas formas de organización del trabajo, donde resulta dificultoso distinguir entre el micro-emprendimiento y la figura del emprendedor, lo cual ha llevado a que muchas veces las políticas públicas, sensibles a la necesidad de apoyar a los grupos poblacionales vulnerables, adquirieran un sesgo pro-pobre, en detrimento de su objetivo principal de incentivar el desarrollo sustentable de pequeñas unidades productivas. El equipo de investigación autor del presente proyecto concluyó recientemente, en el marco de un proyecto PICTOR II, un primer estudio sobre la temática de los micro-emprendimientos en Córdoba, analizando los factores que ayudan a comprender mejor las razones por las que algunos emprendedores alcanzan un mayor éxito que otros, a partir del cual surgieron nuevos interrogantes sobre el rol de la política pública en esta materia, a los que se intentará dar respuesta en esta oportunidad. Más concretamente, en esta investigación se abordarán, ahora con profundidad, diversas cuestiones importantes que analizan el vínculo entre la figura del emprendedor con el micro-emprendimiento que posee y con el efecto general de las políticas públicas en el sector. Uno de los temas es determinar hasta qué punto el comentado sesgo "pro-pobre" estuvo presente en el caso de las políticas públicas aplicadas en Córdoba y qué consecuencias tuvo sobre los micro-emprendimientos y su sustentabilidad. Este aspecto está directamente ligado a la necesidad de discernir acerca de si el fundamento teórico de las políticas públicas diferencia adecuadamente entre el micro-emprendedor y la micro-empresa. Otra importante cuestión a abordar es la de indagar sobre la relación entre capacidad empresarial, capital humano y nivel socio-económico del emprendedor. Resultará de sumo interés identificar los factores que estimulan e inhiben las manifestaciones de capacidad empresarial individual, y establecer su relación con las posibilidades de sustentabilidad del micro-emprendimiento, lo cual debería ser tomado en cuenta por las políticas públicas. El caso de los individuos que se convirtieron en micro-emprendedores como una estrategia para superar la situación de desempleo en que se encontraban, es un tema que será examinado en especial y a la luz de la performance observada del emprendimiento. Serán fuentes primarias de información la Encuesta llevada a cabo en el proyecto PICTOR II arriba mencionado y una re-encuesta a los micro-emprendedores que fueron oportunamente entrevistados. A ello se agregará un estudio de casos de emprendimientos muy exitosos. Los datos de fuentes secundarias surgirán del INDEC, de organismos oficiales y de instituciones no gubernamentales. Los principales métodos y herramientas de análisis a utilizar son los que proporcionan la Estadística, la Econometría y la Micro-economía.

Efficiency and environmental regulation: a 'complex situation'

Production of desirable outputs is often accompanied by undesirable by products that have damaging effects on the environment, and whose disposal is frequently regulated by public authorities. In this paper, we compute directional technology distance functions under particular assumptions concerning disposability of bads in order to test for the existence of what we call ‘complex situations’, where the biggest producer is not the greatest polluter. Furthermore, we show that how in such situations, environmental regulation could achieve an effective reduction in the aggregate level of bad outputs without reducing the production of good outputs. Finally, we illustrate our methodology with an empirical application to a sample of Spanish tile ceramic producers.

Discriminating groups: a comprehensive overview

Discriminating groups were introduced by G.Baumslag, A.Myasnikov and V.Remeslennikov as an outgrowth of their theory of algebraic geometry over groups. However they have taken on a life of their own and have been an object of a considerable amount of study. In this paper we survey the large array results concerning the class of discriminating groups that have been developed over the past decade.

Orientation of the snail Biomphalaria straminea (Dunker, 1848) in response to light in a situation of selection

The behavioral response of Biomphalaria straminea to light was evaluted in terms of location of the snail in a Y-shaped aquarium in a situation of selection and of the rate (cm/hour) and direction of locomotion under homogeneous 9vertical) or differential (horizontal) lighting upon only one arm of the aquarium. The light source consisted of daylight fluorescent lamps with a spectrum close to that of natural light, with illumination varying from 28 to 350 lux. Analysis of the data showed that all animals, whether in groups or isolated, were attracted to light, although the time needed to approach the light source was 50% shorter for the former than for the latter. The rate of locomotion of B. straminea was 35% higher than observed in B. glabrata and 51% higher than that observed in B. tenagophila studied under similar conditions. The results are discussed in terms of social factors and geographical distribution of the three species.
