A importância da criação e aplicação de um modelo de análise pré-investimento, reside no facto dos recursos afectos á promoção serem limitados e escassos, resultando assim numa necessidade de análise sistemática da avaliação do retorno obtido. A importância estabelecida nesta análise deve-se ao facto de os impactos da decisão de investimento terem repercussões ao longo de vários anos, pelo que a flexibilidade da decisão imputada ao decisor é muito reduzida. Neste contexto, realiza-se um estudo que pretende estabelecer os parâmetros necessários para a elaboração de um modelo de avaliação de pré-investimento da promoção turística ao nível da Região Autónoma da Madeira. Das análises efectuadas conclui-se que existe um mecanismo transmissor do investimento em promoção no PIB da RAM. Este mecanismo é estabelecido pela via das receitas turísticas, uma vez que existe um efeito positivo do investimento em promoção turística nas receitas turísticas, e que este por sua vez apresenta também um impacto positivo ao nível do PIB da RAM. No que se refere á avaliação dos investimentos efectuados, não há evidências de existir actualmente ao nível regional, de facto, uma política de avaliação do investimento realizado para todas as acções promovidas, nem de uma avaliação a priori e de auxílio à decisão de investir. Ao aplicar a regra de decisão do Índice de Rendibilidade da Promoção, com base no modelo criado verifica-se que de acordo com os objectivos estratégicos delineados, em consonância com o plano de contratualização estabelecido, o valor obtido é de um Retorno do Investimento de 32,4 vezes, abaixo do obtido ao nível histórico que situa-se nos 60 vezes. Dada a importância que o Turismo detém na Região Autónoma da Madeira, e a impossibilidade de deter recursos elevados para a actividade promocional, assiste-se assim a importância redobrada da aplicação de um modelo que permita aferir e estabelecer de uma forma clara, os objectivos necessários a cumprir para que se obtenha um aumento do retorno.

Investigate intrahospital and neonatal determinants associated to the weaning of very low birth weight (VLBW) infants. Methods: 119 VLBW (<1500g) infants 81 were monitored from July 2005 through August 2006, from birth to the first ambulatory visit after maternity discharge. This maternity unit uses the Kangaroo Method and the Baby Friendly Hospital Initiative. Results: Out of 119 VLBW infants monitored until discharge, 88 (75%) returned to the facility, 22 (25%) were on exclusive breastfeeding (EB) and 66 (75%) were weaned (partial breastfeeding or formula feeding). Univariate analysis found an association between weaning and lower birth weight, longer stays in the NICU and longer hospitalization times, in addition to more prolonged enteral feeding and birth weight recovery period. Logistic regression showed length of NICU stay as being the main determinant of weaning. Conclusion: The negative repercussion on EB of an extended stay in the NICU is a significant challenge for health professionals to provide more adequate nutrition to VLBW infants

This Master s Thesis proposes the application of Data Envelopment Analysis DEA to evaluate the performance of sales teams, based on a study of their coverage areas. Data was collected from the company contracted to distribute the products in the state of Ceará. Analyses of thirteen sales coverage areas were performed considering first the output-oriented constant return to scale method (CCR-O), then this method with assurance region (AR-O-C) and finally the method of variable returns to scale with assurance region (AR-O-V). The method used in the first approach is shown to be inappropriate for this study, since it inconveniently generates zero-valued weights, allowing that an area under evaluation obtain the maximal score by not producing. Using weight restrictions, through the assurance region methods AR-O-C and AR-O-V, decreasing returns to scale are identified, meaning that the improvement in performance is not proportional to the size of the areas being analyzed. Observing data generated by the analysis, a study is carried out, aiming to design improvement goals for the inefficient areas. Complementing this study, GDP data for each area was compared with scores obtained using AR-O-V analysis. The results presented in this work show that DEA is a useful methodology for assessing sales team performance and that it may contribute to improvements on the quality of the management process.

This Masters thesis investigates and analyzes the homoerotic expressions in Fernando Pessoa s poetry and in his heteronyms : Álvaro de Campos, Alberto Caeiro and Ricardo Reis. Through the elaboration of deceptive strategies as a way to escape from the insults and the constraints, the poet by means of creative runaway lines builds up a homoerotic poetry that differ from the established patterns and representational models of the literature. We can find, bearing in mind a problematic sexuality which overflows in the various I s, of the sinuous identities and the movable boundaries, and intense mask games. They become real in poems, especially by means of sensations, yielding the possibility of a queer discourse and generating a homoerotic poetry. Pessoa s homoerotism is, thus, presented amid friendly relationships, smooth spaces, of heterotrophy of the city, or others space and the closet s aesthetics. Based on this, it is noted the articulations of a performance gender as body scripture and inscription, thus establishing a physical-writing which reveals a transgressive sexuality, with multiple entrances and exits, affirmations and denials that originate paradoxes. In this matter, we develop links between Foucault conceptions (2010a, 2010b, 2011) towards the history of sexuality, friendship and the power-knowledge relations with traces of significance and subjectivity, in processes of faciality and BwO (Body-without-Organs) in Deleuze and Guattari (1996). We still consider the ontological questionings towards the Gay dimension in Eribon (2008) and we raise aspects concerning the construction of the idea of masculinity in Bourdieu (2010). Finally, we base ourselves on Sedgwick s 1993 closet epistemological approach, as well as on Butler s 2012 gender and performance theory, also going through a few Bataille 1987 passages about erotism, that redimension the homoaffective images of the Portuguese poet

Conduziu-se este estudo, com o objetivo de avaliar o retorno ao estro pós-parto de ovelhas submetidas a diferentes manejos de mamada. Foram utilizados 56 ovelhas Santa Inês e Bergamácia, 71 cordeiros e 3 rufiões. Os manejos de mamada (MM) foram: 1: contínua; 2: duas mamadas diárias; 3: mamada durante a noite. O período experimental foi dos 15 dias pós-parto até o desmame aos 60 dias. Até os 15, dias de idade os cordeiros permaneceram com suas mães em período integral. No MM 1, as ovelhas permaneceram com seus cordeiros em uma baia, em período integral. No MM 2, as ovelhas passaram a noite em uma baia e o dia em pastagem, momento em que não possuíam contato físico e visual com as crias. Seus cordeiros permaneceram em outra baia em período integral, para onde as ovelhas eram encaminhadas no momento da amamentação. No MM 3, as ovelhas passaram o dia em pastagem e a noite com seus cordeiros em uma baia, na qual os cordeiros permaneceram em período integral. Todas as ovelhas e todos os cordeiros receberam alimentação nas baias. Para identificação das ovelhas em estro foram utilizados rufiões, os quais permaneceram com elas em período integral. Os dados foram submetidos à análise de variância (PROC GLM, Sas®), e as médias comparadas por contrastes. O MM 2 possibilitou retorno ao estro pós-parto precoce quando comparado ao MM 3 e ao MM 1. Houve pouca ou nenhuma influência do anestro lactacional, pois 80% das ovelhas apresentaram estro durante a amamentação.

The annual litter fall production and the concentrations of macronutrients of four leguminous tree species were evaluated. The experiment was installed in a distrophic red yellow latosol (Oxisol), derivative of the Bauru sandstone group. The studied species were: Leucaena leucocephala. Acacia melanoxylon, L. diversifolia and Mimosa scabrella. The experimental design was randomized blocks, with four treatments (species) and four replications. The litter fall was collected in boxes measuring 50×50×10 cm, two boxes by treatment in each block. The material was collected monthly and dried, weighed and chemically analyzed. The litter fall deposition occurred in the following order: M. scabrella (7,051 kg ha -1 ano -1), A. melanoxylon (2,789 kg ha -1 ano -1), L. diversifolia (1,576 kg ha -1 ano -1) and L. leucocephala (1,389 kg ha -1 ano -1). The content of nutrients obeyed the following order: N>Ca>K>Mg>P>S, with the exception of L. leucocephala that presented a bigger content of S in relation to the P.
