Natureza da decisão estratégica em organizações desportivas: estudo das associações de modalidade na Região Autónoma da Madeira

Segundo os pressupostos do planeamento e da gestão estratégica, as organizações desportivas sem fins lucrativos devem aumentar a autonomia e melhorar a capacidade de antecipar e perceber as mudanças do meio envolvente (face às oportunidades e ameaças), e precisam de intervir activamente na formulação de estratégias (Correia, 2000; Handy, 1988; Kikulis, Slack & Hinings, 1995; Pires, 1995; Santos, 2002; Slack & Hinings, 1992; Thibault, Slack & Hinings, 1993; Thibault, 1999). Nesta perspectiva, o estudo procura compreender as decisões estratégicas das associações desportivas (AD’s), o que pressupõe a análise descritiva da estrutura organizacional e dos principais corpos sociais que têm competências em matéria de decisão e desenvolvimento da organização. No âmbito da análise da estrutura interna, e tendo por base o modelo político das organizações - jogos de poder e de interesses (Mintzberg, 1995; Mintzberg, Lampel & Ahlstrand, 2000) - procurámos identificar e descrever o papel dos principais actores e unidades de apoio que evidenciaram maior influência nas decisões da Direcção e nos seus resultados. Assim, e de acordo com as opções epistemológicas e metodológicas, o estudo fundamenta-se segundo uma perspectiva construtivista e interpretativa (Erickson, 1986; Guba, 1990) das intervenções dos actores em contexto de reunião de Direcção, tendo por objectivo central compreender as decisões estratégicas e as suas determinantes (internas e externas). Só através de um acompanhamento próximo e sistemático dos principais actores organizacionais - Presidente da Direcção (PD), dirigentes, gestores desportivos e directores técnicos (DT’s) - podemos identificar os elementos e as suas intervenções, e, consequentemente, compreender e interpretar as lógicas que estão subjacentes ao processo e tomada de decisão.

Imagens do terceiro setor: um estudo com pais e responsáveis financeiros das organizações educacionais

The present report is the result of an applied research in the educational entities of the third sector, aiming to demonstrate whether the financial influences the perception of users on the image of those entities. For both used the prospect of integrative marketing relationship adapting to and developing a set of indicators which bore the measurement of images from the model of Machado et al (2005) and Kotler and Fox (1994). The sample included a total of 187 parents and financial responsibility in 03 (three) institutions of education in Natal / RN. These data were processed by multivariate statistical analysis, factor analysis, linear regression, analysis of cluster and discriminant analysis. The factor analysis also identified 6 images perceived by users of services. Next were the relationships of cause and effect between the financial and images formed. In discriminant analysis, was identified two distinct groups of parents and guardians with financial perceptions similar and well defined. The result of the work shows that the differential level of financial participation of parents and guardians not influence the formation of the images formed from educational institutions of the third sector

Projeto de um edifício para fins educacionais com foco na racionalização do consumo de água

The urban growth without the prior infrastructure has caused many environmental impacts such as the damage to quality of the water resources in the cities. Along with natural scarcity in some regions, this is one of the factors that limit the availability of drinking water. As a result, the conservation of drinking water is becoming one of the major concerns in sustainable architectural projects. Within this context, this dissertation proposes to develop the design of an educational building focusing on water consumption rationalization. The proposed project is located in UFRN Campus at Currais Novos, an area of warm and dry climate and low rainfall. The proposal seeks to integrate ways to reduce water consumption o to architecture, in order to exploit the advantages and savings. After quantifying the benefits achieved, it was concluded that it is possible to reduce significantly the drinking water consumption in educational buildings in universities using three principles: reduction the water consumption at the point of use, replacement of the water source and internal recycling. Calculations and simulations indicated that the proposed building may have water consumption up to 56% lower than if it would be provided by conventional facilities. Rationalization of water consumption brings direct and indirect benefits, with influences on the environmental, social and economic fields

Diferenças de gênero na produção de associações livres de palavras através do ciclo sono-vigília

Although several studies, have shown differences in cognitive performance between men and women, it not yet known whether these differences occur in tasks involving free association of words (WA). Studies across the sleep-wake cycle (SWC) suggest that rapid eye movement sleep (REM) favors semantic flexibility, in comparison with pre-sleep waking (Pre-WK), slow-wave sleep (SWS) and post-sleep waking (Post-WK). The present work has two aims: (1) to evaluate the semantic distances of word pairs produced by AP, comparing men and women, (2) to evaluate semantic distance in word pairs produced by free association across the SWC in young adults of both sexes. To achieve aim (1), we applied a task of WA in 68 adult volunteers during waking (52 women and 16 men). The WA task consisted of writing the first word that came to mind after viewing another word offered as a stimulus (root Word). To achieve aim (2), we performed polysomnography to identify specific stages of the SWC. The experimental subjects were then awakened (if they were asleep) and were immediately given a WA task. The task was administered to 2 groups of 10 subjects each (G1 and G2). G1 subjects were stimulated with the same set of root words after waking from various states of SWC, while G2 subjects received sets of different root words at each state of the SWC. In the absence of a Portuguese corpus suitable for the measurement of semantic distances, the words collected in our experiments were translated to English, and semantically quantified within a systematic and representative corpus of that language (Wordnet). This procedure removed the polysemies typical of Portuguese, but preserved the semantic macrostructure common to both languages. During waking, we found that semantic distances are significantly lower in WA produced by women, in comparison with the distances observed in men. Through the SWC, there were no statistically significant differences in G1. In G2 women, we detected a significant increase of semantic distances upon being awakened from SWS. In contrast, G2 men showed a significant increase in semantic distances upon being awakened from REM. The results of the first experiment are consistent with the notion that women have a more concrete reasoning than men. The results of the second experiment indicate that men awakened from REM present more flexibility in word association than when being awakened from other states. In contrast, women showed more flexible word association after being awakened from SWS, in compared with other states. The results indicate that the cognitive flexibility attributed to different states of the SWC shows gender dependency

Natal como destino turístico : um estudo das imagens (re)veladas pela mídia, pelos turistas e suas implicações educacionais e culturais

This thesis is a result of a research on Natal/RN as a tourist destination. We understand that cities are chosen as tourist destinations beyond its cartographic localization, from other dimensions of meanings that, in its set, constitute images. These images are, probably, very different of the images constructed by native and resident populations, who possess relations of identity with the place. The knowledge of the meanings that others attribute to this city as tourist destination, bring us near to the symbolic bonds established by individuals or social groups on the act of their choices, as well as bring us near to the interaction process city-tourists where the expectations are confirmed or not. The images divulgated by the media also participate of the complex formation of the tourist image that is being constructed and available for the different public, in different social contexts. The tourism constitutes a symbolic asset of the modern society, being considered by the studious, as one of the most expressive phenomena of the modernity, for involving each year displacement and the interaction of thousand of people of different cultures in the entire world. All this people s mobilization points to practical social related to personal motivations, to the entailed desired to the idea to travel and to exceed borders. It is already consensus that tourism is a phenomenon of economic growth, generating jobs, income, professional, qualification, bringing improvements for the host cities. Since 1995, in Brazil, the tourism as a sector of the economy, passed to be considered one of the national priorities, and in this perspective, the national politics of the tourism invested in infrastructure of Brazilian cities with high tourist potential, objecting to increase the flows of Brazilian and foreign tourists. Owing to this fact, the country still invests in programs of tourist marketing, mainly divulging the images of the natural beauties of Brazil abroad. And for Brazilians, the campaigns appeal to rescue the feeling to be Brazilian, associating the idea to travel and know its country. Natal city possesses an excellent positioning in the tourist marketing, being predominantly divulgated in national and international level, for its naturalistic singularity, where the images of its natural enchantments as warm water beaches, white dunes, warm weather, constant breeze and an always blue sky are shown as the favorite scene on this city. From what was viewed above that the choice of a tourist destination articulates from a determined imaginary of a place, already constructed or in process of construction, we consider the knowledge of this imaginary a basic learning for the population of the city and especially, for educators, in the formation of professionals in this area and for tourism managers, elaborators of public politics. Based on this estimative, we developed this research that had as a general objective to identify the images that illustrate Natal city as a tourist destination - our objective of study, particularly the meanings and senses attributed by the tourist marketing (hotel s folders) and by the tourists that visited the city during this study. The discussions and reflections that had guided this research had been given from the theoretical link between imaginary and social representation, also considering some interfaces between the fields of communication and symbol. From the studied authors, Baczko (1985) clarifies that the study of social imaginary is directed for the mechanisms and structures of the social life, especially for the intervention accomplishes and efficient of the representations and symbols in the practical collectives, as well as in its direction and orientation . Following this same thought, Moscovici (1978) says that the social representation are produced in communicational and symbolic contexts, and these representations once that already constituted circulate socially as almost tangible entities. Based on this fundament and on the analyze of Barthes (1990), particularly in the approach given to the reading of photographic image, we could observe on hotel s folders that each page evidences senses and meanings of functionality of internal and external spaces, pointing to the way of leisure offered by the keepers of city which is the hotels. About, the leisure that they offer, it is directed to young public, giving meaning to the young myth of personalized leisure tourism on children, young and adults images. The image about security that hotels offer and the singular image of Natal city as a paradise place, provide an idealization of pleasure through the sun, dunes, and beaches and also due to the hospitability of the natives who are assigned as educated . For the tourist that participated on this research, Natal city is tied only by the imaginary of leisure and nature which constitute the emotional link of the relation media-city-tourist. And with such force and fullness of directions the city discloses without tensions and contradictions as a place protected by a mythical and sacred aura. The study also demonstrates us that the potiguar culture remains (almost) forgotten, due to the silenced in this imaginary. In this perspective, we highlight that this culture silence is very close related to the disvalue of education in its general meaning. We defend that the imaginary apprehended constitutes a new reading and a new looking and understanding the tourist reality that comes historically consolidating in this city. In this direction, we glimpse that this study and its future dismemberments can collaborate with the process of rescue the cultural values of the potiguar people, in the way that the meaning of tourist may be redefined, and the tourist image of the city can be also disclosed for its identities particularities of its culture

Diversidade de hemerobiídeos (Neuroptera) e suas associações com presas em cafeeiros

O objetivo deste trabalho foi avaliar a diversidade de Hemerobiidae (Neuroptera) em cafeeiros, e suas relações com Leucoptera coffeella, Coccus sp., Planococcus sp., Oligonychus ilicis, Brevipalpus phoenicis, Aphis spiraecola e Toxoptera aurantii. As amostragens foram realizadas em Cravinhos, SP, entre maio de 2005 e abril de 2007. Os hemerobiídeos foram coletados com rede de varredura, armadilha de Möricke e armadilhas luminosas e, para a amostragem das presas, foram coletadas folhas de cafeeiro. Foram obtidos 882 exemplares de hemerobiídeos: Nusalala tessellata (467 espécimes, 52,9% do total coletado), Hemerobius bolivari (153, 17,3%), Megalomus impudicus (114, 12,9%), Sympherobius miranda (109, 12,4%), Megalomus rafaeli (30, 3,4%), Sympherobius ariasi (6, 0,7%) e Nomerobius psychodoides (3, 0,3%). A ocorrência de Nusalala tessellata e M. impudicus foi correlacionada positivamente à de Coccus sp.; o mesmo fato ocorreu para M. rafaeli com lagartas de L. coffeella e A. spiraecola e para H. bolivari com O. ilicis. As correlações foram negativas e significativas entre as ocorrências de S. miranda e O. ilicis e entre as de N. tessellata e L. coffeella e O. ilicis. As correlações mostraram que os Hemerobiidae, predadores generalistas, foram favorecidos pelo constante suprimento de presas que ocorreram na cultura do café, no período estudado.

Polimorfismo da transferrina e albumina e as associações com precocidade sexual em bovinos da raça Nelore doadores de sêmen

O presente estudo utilizou 16 animais Bos taurus indicus da raça Nelore doadores de sêmen. Estes animais foram divididos em grupos de acordo com a idade em que o sêmen congelou pela primeira vez. O grupo I, considerado precoce, apresentou animais com sêmen passível de congelação com idade inferior a 20 meses. O grupo II, composto por animais que tiveram o sêmen congelado com idade entre 21 e 26 meses. E o grupo III, tido como tardio, composto por animais com sêmen congelável com idade superior a 27 meses. Para análise dos padrões eletroforéticos da transferrina e albumina, amostras de sangue foram colhidas em tubos heparinizados e submetidos a centrifugação de 2.500 G por 15 minutos para separação do plasma sangüíneo. As amostras de plasma sangüíneo foram processadas para que a corrida eletroforética em gel de poliacrilamida pudesse ser realizada. Para a coloração do gel, usou-se Coomasie Brilliant Blue. Após análise dos padrões eletroforéticos da transferrina e albumina, observou-se que não houve relação detectável entre os fenótipos da albumina e precocidade sexual de touros doadores. Entretanto, em relação à transferrina, foi possível sugerir uma associação entre o alelo TfD com touros portadores de sêmen congelável precocemente ou medianamente em termos de idade à congelação.

Por trás de links, sempre existem pessoas: o anonimato como fator de pertencimento no uso de redes sociais on-line em projetos educacionais

The thesis investigated how social networks online that allows anonymous postings can be used by teachers and students to promote the meeting between the sexual education and the needs and expectations of young people face a crosscutting theme, remarkably a taboo. It needs teaching strategies more efficient than those traditionally defended. With this experience, found in a short course about sexuality and health, we sought to go beyond the use of social networks for social entertainment, showing they can be an field that favors the process of teaching and learning. The research was based on the convergence of the communication concepts from Paulo Frere and another from Jürgen Habermas, as well as the philosophical concepts of utopia, ideology and dialectic are interrelated not only among themselves, but also inside an education field. Methodologically in this thesis, we adopted the category of qualitative research; the method is a combination of case study with action research. The technique was the use of questionnaires, data collection was in attendance and the types of data were primary. Finally, we present, then, the idea the communication is not in the middle, but in the trusty relationship established between the interlocutors. In this way, we can think when a student has met their need to be able answer his questions about sex with their teacher through an online social network that allows anonymity and through which the student knows who responds is their teacher, but the teacher can not distinguish the identity of his students, this dialogic relationship serves to get claims of the validity that are characterized as potential communicative action
