    In the last seven years, the federal governments published Agricultural and Livestock Plans with the proposal of building and working as mechanisms of improvement Brazil agricultural and livestock activities. In order of agribusiness expression and importance for the country, considerations about the influence of these plans into Brazilian productivity have become increasable relevant. The present paper has as a proposal (1) a comparative analyses of each PAP’ characteristics, in the period of 2000/2001 to 2005/2006, studying the official documents published by the Agricultural, Livestock and Food Supply Ministry; (2) a prospective investigation of productivity datas offered by IBGE/Embrapa and; (3) provide, from simple statistical approach and inference, the real performance of livestock in the last six years, and (4) offer bases that help in formulating hypotheses about the programs effectiveness. Recalculated the productivity index, considering the progress in the disposal of matrices since 2001, concluding by the presence of bias in the indicator. The productivity examination, result in positive performance, but lower than recognized. The figures obtained do not have strong enough to unequivocally independent of environmental variables. It is not possible admit that the PAP’s effectiveness fueling the result of the bovine productive chain.agribusiness, agricultural and livestock plan, productivity and investment in agribusiness., Agribusiness, Agricultural Finance, Industrial Organization,

    Wounds and words: A lexical and syntactic analysis of Casocot’s “There are other things beside brightness and light”

    While there has been a sustained interest in conducting stylistic studies on fiction, specifically novels and short stories, the literature about stylistic analysis of flash fiction as a literary genre remains scant. Thus, the present study attempts to conduct a lexical and syntactic analysis of Ian Rosales Casocot’s “There Are Other Things Beside Brightness And Light.” The analysis was anchored in two of the four linguistic and stylistic categories proposed by Leech and Short (2007), namely lexical and grammatical. To communicate the narrator’s traumatic experience, the following lexical categories were found: words that evoke the main character’s recollected sensations, particularly visual; a Latin expression, and slang words; concrete nouns providing access to the feelings of the main character; abstract nouns connoting psychological or emotional processes; and adjectives depicting sensory imageries and representing, along with some verbs, psychological states that carry negative connotations. Stative verbs vis-à-vis dynamic ones echo the impressions of attachment and detachment, and memory in the story, which link to the adverbs of manner in the text. On the other hand, these grammatical features contributed to text interpretation: cumulative or loose sentences depicting a series of rapid thoughts of the narrator who recalls a traumatic experience; mini-paragraphs, i.e., text fragmentation, foregrounding the theme of the narrative; a verb-tense shift from past to future, and the demonstrative pronouns that and this representing the struggle of the narrator to escape from the vexatious memory of pain and trauma; and the em dash paving the way for the narrator’s emotional rumination. The stylistic analysis, particularly lexical and syntactic, provides a more objective and profound understanding of the underlying meanings of the FF under study

    The violence of literature review and the imperative to ask new questions

    Get PDF
    Writing the literature review is not a neutral act. In fact, the key central aim of consolidating work in a particular research area is to demonstrate one’s knowledge of this area; that is, one must know the ‘conversations’ concerning the research topic. Literature review becomes violent in the Bourdieusian sense because it imposes particular configurations of privileged knowledge on researchers. Thus, in this paper, we argue that literature review is an enactment of symbolic violence and, in the process, epistemic theft, and central to this practice is the construction of research questions. Literature review, as a site of scholarly conversations, dictates the kinds of questions we ask, thus unwittingly framing our research according to the epistemic demands of past and recent studies. By asking a different set of questions, ‘new’ or different understandings about certain social phenomena may emerge

    Monitoring and recording changes in natural landscapes: A case study from two coastal wetlands in se italy

    Get PDF
    This study analyzed and evaluated the changes that occurred in two coastal wetlands, characterized by complex and fragmented landscape patterns, in Southern Italy, which were moni-tored over a period of seven years from 2007 to 2014. Furthermore, the performances of two Land Cover (LC) and habitat taxonomies, compared for their suitability in mapping the identified changes, were assessed. A post-mapping method was adopted to detect the habitat/LC changes that occurred in the study period. Various changes were identified, both inter-class changes (class conversions) and intra-class changes (class modifications), and quantified by means of transition matrices. Conversions were easily mapped, while the modification mapping depended on the taxonomy adopted: the Land Cover Classification System (LCCS) allowed the detection of morpho-structural changes in woody vegetation, but the European Nature Information System (EUNIS) showed a higher thematic resolution for the salt marsh types. The detected changes were related to specific impacts, pressures and underlying factors. Landscape indices highlighted different trends in landscape richness and complexity in the two sites. Changes are occurring very quickly in the observed coastal sites and the ongoing dynamics are strictly related to their small size and complexity. For effective monitoring and detection of change in these environments, the coupling of EUNIS and LCCS is suggested

    Amplitud de distribución eritrocitaria como factor de riesgo de mortalidad en pacientes en hemodiálisis

    Get PDF
    La amplitud de distribución eritrocitaria (ADE) elevada ha sido relacionada con morbimortalidad de diferentes enfermedades, entre ellas con enfermedad renal crónica. Pocos estudios han explorado la relación de ADE elevada con mortalidad de pacientes en hemodiálisis, inclusive con resultados contradictorios, por lo cual nuestro objetivo fue determinar si la ADE > 14.9% es un factor de riesgo de mortalidad en pacientes con enfermedad renal crónica (ERC) en hemodiálisis. Material y métodos: realizamos un estudio analítico, observacional, retrospectivo, de casos y controles en 177 pacientes con enfermedad renal crónica en hemodiálisis. La muestra estuvo conformada por 59 pacientes fallecidos (casos) y 118 pacientes vivos (controles) seleccionados por muestreo aleatorio simple. El ADE de los pacientes fue dividido en > 14.9% (ADE alto) y ≤ 14.9% (ADE bajo). Resultados: el 72.9% de los casos presentaron ADE alto comparado con el 44.1% de los controles. Los pacientes con ADE alto presentaron un OR: 3.41 (IC 95% 1.73 - 6.73, p < 0.001). En el análisis multivariado de los factores de riesgo relacionados con mortalidad con diferencias significativas en la muestra total encontramos para anemia un OR ajustado: 2.636 (IC 95% 1.211 - 5.736, p < 0.015). Conclusión: La amplitud de distribución eritrocitaria no es factor de riesgo de mortalidad en pacientes con ERC en hemodiálisis.The elevated red blood cell distribution width (RDW) has been related to morbidity and mortality of different diseases, including chronic kidney disease. Few 5 studies have explored the relationship of high RDW with mortality in hemodialysis patients, even with contradictory results, for which our objective was to determine if RDW > 14.9% is a risk factor for mortality in patients with chronic kidney disease (CKD) on hemodialysis. Material and methods: We conducted an analytical, observational, retrospective, case-control study in 177 patients with chronic kidney disease on hemodialysis. The simple consisted of 59 deceased patients (cases) and 118 living patients (controls) selected by simple random sampling. The ADE of the patients was divided into > 14.9% (high ADE) and ≤ 14.9% (low ADE). Results: 72.9% of the cases presented high RDW compared to 44.1% of the controls. Patients with high RDW had an OR: 3.41 (95% CI 1.73 - 6.73, p < 0.001). In the multivariate analysis of the risk factors related to mortality with significant differences in the total sample, we found an adjusted OR for anemia: 2,636 (95% CI 1.211 - 5.736, p < 0.015). Conclusion: The red cell distribution width is not a risk factor for mortality in patients with CKD on hemodialysis.Tesi

    The active role of organic molecules in the formation of long‐lived reactive oxygen and nitrogen species in plasma‐treated water solutions

    AbstractPlasma‐treated water solutions (PTWS) allow the delivery of reactive oxygen and nitrogen species (RONS) to cells and tissues for different purposes. The mechanism of RONS formation has been clearly modelled in simple liquids like water, by assuming a plasma‐driven process independent from the liquid. PTWS for biological experiments, however, are often produced from solutions of complex composition, where the formation mechanism of RONS is far from being understood. In this paper, we describe how water, phosphate‐buffered saline solution and two cell culture media were plasma‐treated in different conditions to demonstrate how the different composition of the liquids affects the formation of stable RONS (H2O2 and NO2−) in the resulting PTWS, especially when aromatic organic molecules are present
