The effect of high-fat diet on rat’s mood, feeding behavior and response to stress

An association between obesity and depression has been indicated in studies addressing common physical (metabolic) and psychological (anxiety, low self-esteem) outcomes. Of consideration in both obesity and depression are chronic mild stressors to which individuals are exposed to on a daily basis. However, the response to stress is remarkably variable depending on numerous factors, such as the physical health and the mental state at the time of exposure. Here a chronic mild stress (CMS) protocol was used to assess the effect of high-fat diet (HFD)-induced obesity on response to stress in a rat model. In addition to the development of metabolic complications, such as glucose intolerance, diet-induced obesity caused behavioral alterations. Specifically, animals fed on HFD displayed depressive- and anxious-like behaviors that were only present in the normal diet (ND) group upon exposure to CMS. Of notice, these mood impairments were not further aggravated when the HFD animals were exposed to CMS, which suggest a ceiling effect. Moreover, although there was a sudden drop of food consumption in the first 3 weeks of the CMS protocol in both ND and HFD groups, only the CMS-HFD displayed an overall noticeable decrease in total food intake during the 6 weeks of the CMS protocol. Altogether, the study suggests that HFD impacts on the response to CMS, which should be considered when addressing the consequences of obesity in behavior.

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.

The influence of patient's consciousness regarding high blood pressure and patient's attitude in face of disease controlling medicine intake

OBJECTIVE: To assess the relation between blood pressure control and the following: the Morisky-Green test, the patient's consciousness regarding high blood pressure, the patient's attitude in face of medicine intake, the patient's attendance at medical consultations, and the subjective physician's judgment. METHODS: We studied 130 hypertensive patients with the following characteristics: 73% females, 60±11 years, 58% married, 70% white, 45% retired, 45% with incomplete elementary schooling, 64% had a familial income of 1 to 3 minimum wages, body mass index of 30±7 kg/m², consciousness regarding the disease for a mean period of 11±9.5 years, and mean treatment duration of 8 ±7 years. RESULTS: Only 35% of the hypertensive individuals had blood pressure under control and a longer duration of treatment (10±7 vs 7±6.5 years; P<0.05). The retiree predominated. The result of the Morisky-Green test did not relate to blood pressure control. In evaluating the attitude in face of medicine intake, the controlled patients achieved significantly higher scores than did the noncontrolled patients (8±1.9 vs 7 ±2, P<0.05). The hypertensive patients had higher levels of consciousness regarding their disease and its treatment, and most (70%) patients attended 3 or 4 medical consultations, which did not influence blood pressure control. The physicians attributed significantly higher scores regarding adherence to treatment to controlled patients (6±0.8 vs 5±1.2; P<0.05). CONCLUSION: Consciousness regarding the disease, the Morisky-Green test, and attendance to medical consultations did not influence blood pressure control.

Procesos adaptativos y dimensiones del comportamiento biosocial en cazadores recolectores del SW de la provincia de La Pampa.

Resumen del proyecto: Este resumen se incluirá en la base de datos de la Biblioteca Digital del Ministerio, por lo que se debe elaborar el mismo sobre la base de la siguiente estructura y completar todos los campos que se indican a continuación: identificación y caracterización del problema objeto del estudio, hipótesis, planteo de objetivos, materiales y métodos a utilizar, resultados esperados, importancia del proyecto (extensión del campo 4000 caracteres). Proyecto diseñado para aportar al conocimiento de los procesos adaptativos y la dinámica biosocial de las sociedades del pasado prehistórico argentino. Propone analizar y evaluar el potencial documental de los restos bioarqueológicos con fehaciente asociación contextual para posibilitar la realización de inferencias sobre procesos biosociales de naturaleza adaptativa o no adaptativa. Está centrado en el análisis osteológico y biocultural de materiales esqueletales (aproximadamente cien individuos) correspondientes a poblaciones aborígenes prehistóricas del actual territorio de la provincia de La Pampa (Médano Petroquímica, Departamento Puelén). Entre otros muchos aspectos, la importancia de estos materiales reside en que son asignables a sociedades con economía cazadora-recolectora y cuya cronología corresponde al Holoceno tardío final (Entierros datados en 393 ± 41 cal AP AMS.), una época particularmente interesante por la dinámica sucesión de eventos socioculturales y poblacionales que la caracterizan. La evidencia recuperada da cuenta de prácticas funerarias complejas que consisten en la realización de enterratorios colectivos, indirectos, secundarios, y presencia de eventos de violencia y/o tensión social. Los métodos y técnicas consisten en la descripción e identificación basados en observación y registro de marcadores esqueléticos conforme a prácticas estándares de nuestro laboratorio: Planillas de observación y registro durante excavaciones de la Archaeological Summer Field School (ASFS) de la Universidad de Chicago y planillas de los “Standards” de Buikstra y Ubelaker, modificadas y adaptadas por nuestro grupo de trabajo, entre otros). Los datos obtenidos serán empleados para graficación (estadística descriptiva) y también se realizará sobre ellos análisis multivariados y estadística no paramétrica (etapa inferencial). Se tendrán en cuenta aspectos descriptivos y analíticos vinculados con el reconocimiento de la edad y el sexo, hábitos dietarios (marcadores morfológicos y químicos de hueso y dientes), economía de subsistencia, patrones de diferenciación social, exploración de eventuales relaciones de parentesco, roles vinculados con el sexo, el uso del cuerpo, dieta, salud y enfermedad, en relación con la economía de subsistencia, etc. (Buikstra y Beck 2006, Larsen, 1997, White y Folkens 2000). Dado la naturaleza y complejidad de los hallazgos, caracterizados por la conformación de entierros colectivos secundarios e indirectos, un capítulo de interés lo constituye el análisis de las dimensiones sociales del comportamiento mortuorio y la discusión de los indicadores de violencia y/o tensión social asociados a los hallazgos (O´Shea 1984, Rakita et al. 2005, entre otros). Dado el hecho de que se cuenta con la disponibilidad de materiales adecuados para este tipo de estudios, la información relevante y los datos a analizar serán obtenidos mediante la aplicación de métodos y técnicas bioarqueológicas específicas antes mencionados, con la finalidad de observar y discutir tendencias y proponer modelos de interpretación sujetos a ulterior validación, particularmente toda vez que se cuente con una mayor representación numérica y casuística tanto a nivel de individuos como de sitios bioarqueológicos excavados. El proyecto se enmarca en la firma de un Convenio Específico de Trabajo entre la UNRC y el Gobierno de La Pampa.

Abstract: Resumen del proyecto en inglés (extensión del campo 2000 caracteres). This project has been designed to improve the knoledge on adaptive processes and biosocial dynamics among aborigine past societies in Argentina. This research is focused on the analysis and evaluation of documentary potential of bioarchaeological skeletal remains with reliable contextual associations. It is specifically centered in the osteological as well as cultural analysis of more than one hundred skeletons from native prehistoric populations from a prehistoric collective burial site in La Pampa province. (Médano Petroquímica, Departamento Puelén). Among other aspects, the importance of the materials to be analyzed lies in the fact that they correspond to a subsistence economy based on hunting and gathering, and have been chronologically assigned to Late Holocene times (burials dated 393 ± 41 cal AP AMS), a period denoting particular interest due to the dynamic succession of sociocultural events that characterized it. Evidence so far recovered accounts for complex funerary practices consisting of indirect, secondary collective burials, as well as the presence of events of violence and/o social tension. Methods and techniques consist in the description and identification based on the observation, and recording of skeletal markers, according to laboratory as well as field work standards: The University of Chicago Archaeological Summer Field School (ASFS) forms, and the “Standards” forms from Buikstra y Ubelaker (1994), modified and adapted by our research team, among others. Data obtained shall be used for graphic (descriptive statistics) as well as multivariate analyses and non parametric statistics (inferential stage). Descriptive as well as analytical aspects such as those related to age and sex determination, feeding habits (morphological as well as chemical markers of bones and teeth), subsistence economy, patterns of social differentiation, kinship patterns, sex-linked roles, body use, diet, health and disease, all of them in close relationship with the hunter-gatherer subsistence economy (Buikstra y Beck 2006, Larsen, 1997, White y Folkens 2000). Given the nature and complexity of the burial disposals, characterized by complex collective burials, a core chapter of our interest is that of social dimensions of mortuary behavior as well as the discussion and interpretation of markers of violence and/or social tension. Given the amount of evidence gathered so far, relevant information as well as data to be analyzed will be obtained by specific bioarchaeological methods and techniques, trying to observe and discuss possible trends as well as to formulate interpretive models to be verified or rejected with the arrival of new, reliable data both at individual level as well as at the archaeological sites to be excavated. This project has been particularly considered in a bilateral agreement between UNRC and the Government of La Pampa Province.

Prácticas comunicativas forenses: Las relaciones intertextuales en el examen de testigos. Forensic communicative practices: intertextual relations in examination of witnesses.

Inscripto en el análisis del discurso interaccional de tradición angloamericana y optando por un abordaje metodológico etnográfico, este proyecto plantea investigar las relaciones entre textos orales y entre textos orales y escritos vinculados en cadenas textuales en un acontecimiento comunicativo institucional en el que tales relaciones tienen consecuencias directas en la confiabilidad de la información e intervienen en la construcción del conocimiento oficial. La situación comunicativa elegida es el examen y el contraexamen de testigos comunes durante procesos penales orales, de formato común no abreviado, en la jurisdicción de Córdoba capital. En las interacciones verbales con litigantes y jueces en las que emerge el testimonio se ponen en juego otros textos orales (en forma de citas de lo dicho antes por el mismo testigo u otras personas, referencias a rumores u opiniones colectivas, etc.) y textos escritos (actas de secuestro, informes periciales, actas de las declaraciones testimoniales en la etapa de instrucción, etc.). El foco de atención son las prácticas asociadas a la intertextualidad puesto que condicionan el carácter de la prueba testimonial producida ante el juzgador. Postulamos que los litigantes despliegan tácticas locales y estrategias globales reconocibles y recurrentes vinculadas al tratamiento de diversas categorías de textos previos. Además, planteamos averiguar si la participación de los jueces en interacción con los testigos es de suficiente injerencia como para ser un modo importante de generación de prueba testimonial. El enfoque metodológico general es etnográfico y analíticodiscursivo. Se seleccionará una causa por delito grave, se presenciará el debate en la cámara y se registrará el audio de todas las audiencias. Los datos a analizar serán los segmentos en las interacciones en los que se incorpora la lectura o se cita las actas de las declaraciones indagatorias o testimoniales anteriores, y los segmentos en los que se requiere, en calidad de prueba testimonial, la reproducción de dichos. Se procederá a partir de los detalles de la superficie textual y la pragmática de los intercambios y aprovechando el valor heurístico del concepto de voz, buscando identificar patrones recurrentes y los mecanismos generales que los rigen. Sobre esa base, se considerarán los intercambios verbales como interacción social que emerge moldeada por condiciones situacionales e institucionales y otros factores, tales como la incidencia de la pertenencia a grupos sociales o profesionales. Con el estudio se obtendrá una visión de prácticas cotidianas asociadas a la intertextualidad que son de crucial importancia para el carácter de la prueba testimonial producida ante el juzgador. Este paso nos acercará a conocer cómo se lleva a cabo efectivamente la administración de justicia penal y permitirá valorar los patrones de conducta a la luz de las normas procesales. In line with the Anglo-American tradition of situated discourse analysis, this project aims at tracing the links between oral texts and between oral and written texts related in textual chains which are present in an institutional event in which such relations have a direct consequence on the reliability of the information given and have an impact on the construction of what counts as official knowledge. The communicative situation under study is that of the direct and cross-examination of lay witnesses during a criminal trial in the city of Córdoba. During the face-to-face interactions between trial lawyers and judges in which the testimony takes place, other oral texts and written texts get incorporated. The focus of this research is centered on practices of intertextuality as they condition the nature of the oral evidence produced. It is argued that trial lawyers use recurrent local tactics and global strategies that are related to the treatment given to different categories of previous texts. Another aim of this study is to examine if judge’s interventions have an impact on the generation of the oral evidence. The data will come from a criminal trial that will be audio-taped in its entirety. Ethnographic observations of a criminal trial will be made. The focus of analysis will be on segments of interactions in which previous texts are read aloud or incorporated as quotes. After carrying out a detailed analysis of the surface of texts and the pragmatics of the exchanges, recurrent patterns and the general mechanisms that condition their emergence will be described. In this way, verbal exchanges will be considered social interactions that unfold conditioned by situational, institutional and social factors. This study will examine the relationship between intertextuality and the institutional practice of providing oral evidence. This will help understand how justice is actually administered and how patterns of behavior are valued according to institutional norms.

Non root feeding with two sources of zinc on Coffea arábica L. 'mundo novo'(B.Rodr.) Choussy

A trial was carried out on an eight old coffee plantation with visible zinc problems. The plantation was situated nearly the city of Jaú (22º30'S, 48º30'W). State of São Paulo, Brazil. The soil is classified as medium texture Oxisol of low base saturation (Latossol Vermelho Amarelo - fase arenosa). The pulverization program started in november 1977, followed in march and July 1978 (heavy harvest) and ended in march and July 1979 (light harvest). Is should be mentioned that a well reconized characteristic of arábica coffe is its habit of biennial bearing, a very heavy harvest is most often followed by a light load the next year. The following treatments and amounts of chemicals per cova hole (4 trees) were tested in accordance with a random block design: 1. 1 g of zinc (zinc sulphate, 0.5%) 2. 3 g of nitrogen (urea, 1.3%) 3. 1 g of zinc + 3 g of nitrogen (zinc sulphate 0.5% + urea 1.3%) 4. 0.25 g, 0.50 g, 1.00 g, 2.00 g of zinc plus 0.75 g, 1.50 g, 3.00 g and 6.00 of nitrogen (correspondent to NZN* 15-0-0-5 as 0.75%, 1-5%, 3.0% and 6.0% by v/v). Foliar absorption data were obtained by collecting the 3rd and 4th pairs of the coffee leaves and analysed them for N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, and Zn. The main results may be summarized as follows: 1. The maximum calculated yields of clean coffee were obtained by the applications of 5.84 1 of NZN (1.13%) per hectare. 2. The applications of zinc sulphate (0.5%) and urea (1.3%) together or separate did not affected the coffee bean production. 3. The applications of 15.0 1 of NZN per hectare reduced the coffee yields. 4. Leaf damages and burning symptoms were observed by the applications of urea (1.3%) plus zinc sulphate (0.5%) and larger doses than 7.5 1 of NZN per hectare. 5. Leaf tissue analysis show that the concentrations of the elements were affecred by the age of the leaves and by the yields of the coffee trees. 6. The applications of increasing doses of NZN causes an increase in the concentration of zinc, manganese and boron in the leaves and decreased the concentration in calcium and potassium the leaves. 7. The concentration of zinc in the leaves associated with the heavy harvest, in July, was 70.0 ppm.

Controlling für einen Onlineshop

Die vorliegende Masterarbeit beschäftigt sich mit dem Thema Controlling für einen Onlineshop. Die Bearbeitung untergliedert sich in zwei Aufgabenschwerpunkte. Zunächst wird die Frage geklärt, inwieweit sich die Anwendung von Webanalytics im Vergleich zum klassischen Vertriebscontrolling für einen Einzelhandelsgeschäft unterscheidet. Um die Fragestellung zu beantworten, werden Gemeinsamkeiten und Unterschiede für beide Ausprägungen des Handels verglichen. Im Ergebnis zeigt sich, dass Vertriebscontrolling für den Einzelhandel und einen Onlineshop anwendbar sind. Webanalytics hingegen kann als Instrument von Webcontrolling betrachtet werden. Webcontrolling stellt sich als Ausprägung des Vertriebscontrolling dar, das sich speziell um die Auswertung und Analyse der Besucher auf einer Webseite beschäftigt. Im zweiten Teil der Arbeit wird auf die praktische Umsetzung für einen Onlineshop hingearbeitet. Der Onlineshop wird dabei in einem gesamten Kontext untersucht. Es werden Aufgabenschwerpunkte erarbeitet, auf die bei der Erstellung eines Onlineshops zu achten ist. Im Ergebnis wird ein Shopsystem vorgestellt, welches für den Einstieg in das Onlinegeschäft verwendet werden kann.

Feeding of two Cichlidae species (Perciformes) in an hypertrophic urban lake

Diet of two cichlid species, Cichlasoma facetum (Jenyns, 1842), and Gymnogeophagus rhabdotus Hensel, 1870, was studied in Rodó Lake, an urban hypertrophic lake in Uruguay. The stomach contents from 192 individuals of C. facetum and 202 of G. rhabdotus, obtained through seasonal sampling in the year 2000, were analyzed. The occurrence frequency and the alimentary importance index of each food item were calculated for each season and size class in both species. Cichlasoma facetum fed upon insects (mainly chironomid larvae and pupae), fish (Cnesterodon decemmaculatus Jenyns, 1842), and vegetals (algae, periphyton and macrophytes debris); large individuals also fed upon the freshwater shrimp Palaemonetes argentinus Nobili, 1901. Gymnogeophagus rhabdotus consumed zooplankton (mainly copepods), vegetals (algae and detritus) and Chironomidae larvae in a lesser extent.

Feeding habits of six anuran (Amphibia: Anura) species in a rainforest fragment in Northeastern Brazil

Although Brazil encompasses one of the most abundant anuran faunas in the world, quantitative information on anuran ecology and diet are limited, especially in the Northeastern region. We analyzed the diet of six species: Hyla albomarginata, Hyla cf. branneri, Hyla minuta, Phyllomedusa aff. hypochondrialis (Hylidae), Leptodactylus natalensis, and Physalaemus cuvieri (Leptodactylidae) in a temporary pond in a rainforest remnant in Pernambuco, between 1999-2000. We analyzed diet composition, degree of food preference, and seasonal variations in diet. Leptodactylus natalensis and P. cuvieri showed higher diet diversity, whereas H. minuta consumed fewer food items. Insecta, Arachnida, and plants were preferential items for most species. Acari were consumed by all species; Hymenoptera, Odonata, and Coleoptera were also often consumed. A slight increase in diet diversity occurred in the rainy season. The species showed a generalist feeding behaviour, although P. cuvieri consumed Formicidae as major prey item.
