Sobre (vivência) e mortalidade de pequenos negócios: o caso de mercados varejistas potiguares

This paper‟s starting point was the objective of understanding the relation between the reasons pointed out by small businesses owners for the continuity or shutdown of their businesses, and the reasons presented by the Environmental Theories. The paper discusses the Environmental Theories understand that it is supported by a systemic metaphor speech, discussing the theme in terms of organizational survival and mortality . The text reviews the literature showing the changes in the administrative thinking regarding the organization versus environment relation, and presenting general ideas about the micro and small businesses. In methodological terms, the qualitative approach was used in the research. Regarding the data collection technique, an in-depth thematic interview was used. It was carried out considering the elements of the techniques of life history and oral history, always giving priority to real world related narratives told by the interviewed subjects. The empirical corpus of the research was made up of seven owners of small retail businesses in two Potiguar cities: Natal and Mossoró. The interpretative and analytical process focused, at first, on the reflexive dialogue with each one of the owners‟ professional life history and business management experience, constituting the first level of analysis: reflections on individual narratives; and, afterwards, the interpretative process was developed through the analysis of all the subjects‟ statements, identifying the recurring themes and constituting the second level of analysis: reflection on the totalizing narrative. The themes identified in the totalizing narrative, that refer to the continuity of the businesses are: evolution, control, fidelity, liking what one does for a living. The themes that came up as reasons for shutdown are: lack of empathy with the business, lack of evolution, competition problems, suppliers and the government. The text synthesizes its comprehensions affirming that the reasons associated with continuity and shutdown of small markets, for this group of owners specifically, come up as a permanent tension between the volunteerism (quite human) and the determinism (systemic). The tension is shown in testimonies that at the same time evoke the organicist systemic logic through the themes evolution/no evolution, and also counterpoints with themes related to the interested human action, based on desires, feelings and personal convictions such as: liking what one does/ lack of empathy. As for the reflexive dialogue between the postulates of the Environmental Theories and the narratives, the results make it possible to affirm that, differently from the tension expressed by the subjects while talking about their reasons, the reasons associated with survival and mortality of businesses according to the Environmental Theories are theoretically polarized, seeming to preach options that are stagnated and shaping towards the subjects involved in the organization-environment relation

Biologia alimentar e morfohistologia do tubo digestório do mussum, synbranchus marmoratus, bloch (osteichthyes: synbranchidae) no açude Marechal Dutra Gargalheiras , localizado no semi-árido brasileiro

Food habits and morpho-histology of the digestive tract of marbled swamp eel, Synbranchus marmoratus (Block, 1917) were investigated. The fish samples were captured during August, 2007 to July, 2008 in the Marechal Dutra reservoir, Acari, Rio Grande do Norte. The rain fall data was obtained from EMPARN. The fish captured, were measured, weighed, dissected, eviscerated and individual stomach weights were registered. The stomach contents analyses were carried out based on volumetric method, points, frequency of occurrence and applying the Index of Relative Importance. The degrees of repletion of the stomachs were determined besides the Index of Repletion relating to feeding activity variations and frequency of ingestion during the rainy and dry seasons. The rainfall varied from 0 mm a 335 mm with a mean value of 71.62 mm. Highest rainfall of 335.5 mm was registered in March, 2008 and August to December was the dry period. During the dry period the study species presented high degrees of repletion of the stomachs, with a peak value in the month of September (mean = 4.54; ± SD = 0.56). The minimum mean value of = 3.99 ± SD = 0.25 was registered in the month of May during the rainy period. The stomach contents of S. marmoratus registered show that this fish prefers animals, 78.22% of crustaceans 2.85% of mollusks, 3.25% of fish, 1.4% of insects and 13.5% of semi-digested organic matter, thus characterizing the study species as a carnivore with a preference for crustaceans. The morpho-histological aspects of the digestive tract of S. marmoratus indicate that the mouth is terminal adapted to open widely, thin lips with taste buds, small villiform teeth forming a single series on maxillas, four pairs of branchial arches with short and widely spaced branchial rays. The oesophagus is short and cylindrical with a small diameter. The oesophagus wall is thick with mucas surface and internal parallel folds. The stomach is retilinical in form, presenting cardiac, caecal and pyloric portions. The caecal portion is long and is intermediary in position between the cardiac and pyloric portions. The cardiac portion of the stomach is short and cylindrical formed of simple epithelial cylindrical mucus cells. The caecal portion is long with narrow walls, a big cavity and smaller folds which give rise to gastric glands. The phyloric portion has no glands and primary or secondary mucas folds. The morphohistological aspects of the digestive tract of S. marmoratus indicate its adaptation to a carnivorous feeding habit

A Fruticultura Irrigada de pequenos produtores no Baixo-Açu: Uma análise da eficiência de custo

This work has as an objective analyze the efficiency of producers costs of the irrigation Project Baixo-Açu , and identify the determining factors of this efficiency. To achieve these targets it was estimated, in a first stage, a frontier of costs by the method, non parametric of Data Envelopment Analysis-DEA, and measured the stakes of efficiency producers. On the second stage, it was utilized the Tobit regression pattern, estimating an inefficiency function of costs, and were indentified the associated factors of resources waste. Among the results found it was noticed the existence of a high waste of resources, that represent more than 54% of effective cost. Among the factors with the highest wastes are: energy, herbicides, defensives and chemical fertilizers. In a general way, the producers presented low efficiency level and, only, two, of seventy-five researched, achieved the frontier of costs minimization. These results reveal, in a certain way, that the producers in irrigated fruit growing in the project Baixo-Açu don t seek to minimize the production costs. It was still noticed, that the reduction of resources waste, and this way the inefficiency of costs, is associated with the agriculturalist education, his experience in agriculture, his access to the technical assistance and credit

Progresso científico em pequenos ruminantes na primeira década do século XXI

O interesse pelos pequenos ruminantes aumentou nos últimos anos sob os aspectos produtivo e científico. No Brasil, caprinos e ovinos são os que despertam maior interesse econômico. Assim, este trabalho foi conduzido com o objetivo de discutir o progresso científico com caprinos e ovinos nos últimos dez anos. Foram pesquisadas várias bases de dados, entre elas as do Institute for Scientific Information (ISI), da Scientific Electronic Library Online - SciELO, da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES, do Instituto Brasileiro de Geografia e Estatística - IBGE e da Food and Agriculture Organization of the United Nations - FAO. Na última década, os pequenos ruminantes têm merecido especial atenção dos pesquisadores, o que pode ser comprovado pelo aumento de 41% nas publicações mundiais envolvendo estas espécies, o que foi acompanhado por aumento ainda mais expressivo, 219%, em âmbito nacional. A evolução também foi observada sob os aspectos metodológicos dos projetos, ressaltando a abordagem multidisciplinar nas pesquisas mais atuais. Nos últimos dez anos, houve crescimento do aporte de recursos para editais temáticos demandados pela sociedade e pela cadeia da carne e do leite, além da preocupação com qualidade, competitividade e sustentabilidade.

GESTÃO AMBIENTAL E COMPETITIVIDADE EM DESTINOS TURÍSTICOS: percepção dos gestores de pequenos meios de hospedagem de Natal/RN sobre o uso de práticas ambientais como fator de competitividade

The present work aimed at investigating the small hotel managers perceptions from Natal/RN concerning the environmental practice uses as a competitive factor. This study is characterized as a descriptive exploratory research that used an aleatory probabilistic sample followed by the application of collect data instrument (questionnaire). The small hotels located in Natal/RN were the study participants and the specific location where 35 questionnaires were answered. Based on the data and on the mangers point of view, it is possible to comprehend that, among the presented indicators, the development of environmental programs in the hotel enterprise is showed as the least important for the client s choice. As the main conclusion it is relevant to argue that, according to the small hotel managers, the guests do not still search for hotels that implement environmental practices. On the other side, the interviewed managers believe that the use of these practices can generate a great competitive advantage in relation to their competitors. The information obtained by this present research will be able to contribute to establish a contemporary panorama in relation to the importance attributed by the managers concerning the use of environmental practices in small hotel enterprises in Natal/RN. In addition the correct use of this information can generate possibilities of major competitiveness in this segment

Estudo vídeo-polissonográfico em recém-nascidos de termo pequenos para a idade gestacional

Analisamos o exame video-polissonográfico de 26 recém-nascidos de termo (RNT) com 24 horas de vida. Os RN tinham exame neurológico e ultrassonográfico cerebral normais e apresentaram período perinatal isento de complicações. Foram subdivididos em dois grupos, um controle constituído de 11 RNT com peso adequado para a idade gestacional; e um grupo de 15 RN com peso abaixo do esperado para o termo (RNT-PIG). do segundo grupo, 13 RN apresentaram algum tipo de alteração ao exame video-polissonográfico. As alterações mais frequentes foram na arquitetura do sono, 11 casos, e no comportamento, em que oito RN apresentaram número excessivo de sobressaltos (startle) em relação ao grupo controle e dois RN uma atividade motora reduzida. Os resultados deste estudo demonstram a utilidade da video-polissonografia quando aplicada a RNT-PIG. O exame mostrou-se sensível em detectar diferenças no comportamento, arquitetura do sono e padrão eletrencefalográfico dos RNT-PIG quando comparados ao grupo controle.

The cases occurred predominantly in animals aging from five days to two years, in winter season, with history of recent wounds or surgical procedures. Muscle rigidity and muscular tremors (72.0%), tachycardia/dyspnea (54.5%), change of placement of ears (45.4%), protusion of the third eyelid (27.2%), hypersensitivity to external stimulus (18.1%), and elevation of ears (18.1%) were the most common clinical signs.

Técnicas cirúrgicas para urolitíase obstrutiva em pequenos ruminantes: relato de casos

Relataram-se dois casos em que a penectomia com transposição peniana perineal foram as técnicas cirúrgicas de escolha e que resultaram em 50% de sucesso. Quatro casos em que as cistotomias seguidas de cistostomias apresentaram 100% de sucesso, um caso em que só a cistotomia foi realizada e não se obteve sucesso, um caso em que apenas o tratamento clínico foi eficiente e dois casos em que houve 100% de insucesso, independentemente da técnica cirúrgica utilizada, devido ao quadro avançado de azotemia e choque toxêmico dos animais. O estudo foi realizado durante os anos de 2003 a 2005, com a casuística de urolitíase obstrutiva em caprinos e ovinos, de forma a descrever as causas e as conseqüências das decisões terapêuticas empregadas.
