O ARMÁRIO DE DEUS NO ARMÁRIO DOS HOMENS. ALTERNATIVAS TEOLÓGICAS PARA O ACOLHIMENTO E LIVRE EXPRESSÃO DA PESSOA HOMOSSEXUAL NA COMUNIDADE CRISTÃ BRASILEIRA DA CONTEMPORANEIDADE

Esta tese parte de uma análise que alia elementos do método histórico-crítico com o histórico-social, privilegiando a análise do discurso, com a finalidade de apresentar alternativas teológicas que dêem conta de pensar a possibilidade e viabilidade de que pessoas homossexuais possam expressar sua espiritualidade de forma livre e completa nas comunidades cristãs brasileiras. A investigação ensejada, procura apresentar um panorama da homossexualidade no Brasil, pontuando momentos diversos, valores, projetos e colocando em relevo a questão da identidade homossexual, principalmente, uma referência à mesma como perversão, anormalidade, crime e doença, reservando às pessoas homossexuais, o estigma, marginalização e exclusão. A investigação proposta apresentará também a busca por uma identidade alternativa por parte das pessoas homossexuais, tanto do ponto de vista teórico, procurando novas possibilidades conceituais, quanto do ponto de vista político, articulando-se em busca de seus direitos como cidadãos. Procurar-se-á perceber de que maneira o cristianismo no Brasil, em sua vertente católica e protestante, compreende a homossexualidade, quais os seus argumentos, ensinos e posturas principais. A partir de tal análise, buscar-se-á perceber quais os principais pilares erguidos pelas alternativas teológicas no sentido de entender como viável, legítimo e possível a livre expressão da pessoa homossexual nas comunidades cristãs. Destacar-se-á a desconstrução de gênero em sua referência binária masculino/feminino, como prejudiciais ao entendimento e convivência com a diversidade e complexidade de identidades sociais e, a extensão desse projeto a uma desconstrução necessária da concepção de Deus numa e sob uma caracterização masculina.(AU)

O PAPEL CONTRADITÓRIO DO PROFESSOR EVENTUAL DA REDE PÚBLICA DE ENSINO DO ESTADO DE SÃO PAULO NA ARTICULAÇÃO DAS RELAÇÕES DE TRABALHO E PROFISSÃO DOCENTE: LÚMPEN-PROFESSORADO ?

Esta pesquisa busca diagnosticar como ocorre a contratação e a atuação do professor eventual do EF II e EM na rede pública de ensino do estado de São Paulo e se essa forma de contratação e de atuação é a causa da quase inexistência desse professor nessa rede. Parte da hipótese de que a forma de contratação coloca esse professor em situação de lúmpen-professorado e que a pouca procura pelo professor eventual para o desempenho dessa função relaciona-se a esse fato, intimamente ligado ao não reconhecimento da importância de sua atuação, ao caráter contraditório do seu papel e às condições em que se dá seu exercício, levando-o a deixar de procurar esse tipo de atividade. Objetiva-se apresentar, discutir e promover uma reflexão a respeito desses temas e contribuir com estudos sobre o assunto, para uma possível análise e quiçá estruturação de uma política educacional adequada nesse âmbito. A carência de estudos sobre o tema justifica esta pesquisa. A partir da revisão bibliográfica, levantaram-se autores que abordaram o assunto, porém, sob outros pontos de vista. A metodologia abrangeu a leitura da bibliografia básica e complementar, a pesquisa documental (legislação federal e do estado de São Paulo), paralelamente a um estudo de caso e pesquisa qualitativa. Numa contextualização histórica geral, priorizaram-se as mudanças nas relações de trabalho e profissão docente, a construção e desconstrução de direitos adquiridos pelo professor, publicados em legislação específica, e, nesse ínterim, a figura do professor eventual. Abordou-se, então, numa perspectiva teórica, a situação precária da profissão docente e suas consequências, mostrando-se o panorama da deterioração do magistério público. O estudo de caso foi realizado por meio de observação sistemática numa escola estadual da periferia do Grande ABC (SP), além da coleta de depoimentos e/ou entrevistas junto a três professores eventuais, três gestores, um gerente de organização escolar e do secretário adjunto da Secretaria da Educação do estado de São Paulo, no intuito de valorar recortes dos diversos olhares. O estudo encerra-se com a discussão sobre a articulação entre os elementos de pesquisa. Os resultados contemplaram as questões propostas quanto à atuação e à contratação do professor eventual, confirmando assim as hipóteses levantadas para a pesquisa.

A (R)EXISTÊNCIA DAS VOCACIONADAS AO MINISTÉRIO PASTORAL BATISTA: DESCORTINANDO A RELAÇÃO ENTRE AS PASTORAS BATISTAS DE SÃO PAULO E A NÃO FILIAÇÃO NA ORDEM DOS PASTORES BATISTAS DO BRASIL EM SÃO PAULO (OPBB-SP)

O contexto batista é predominantemente marcado por lideranças masculinas, destinando às mulheres apenas lugares e comportamentos socialmente estabelecidos, como a casa, o cuidado, a maternidade, a submissão, entre outras características que enfatizam a hierarquia de gênero. Mesmo diante do desenvolvimento econômico e da ocupação que as mulheres estão conquistando no campo público, a igreja e principalmente as igrejas batistas, permanecem fundadas em alicerces que exaltam o poder masculino em detrimento do lugar que deve ser ocupado pelas mulheres, ou seja, onde elas decidirem atuar. Caso elas decidam atuar num campo predominantemente masculino, terão que lidar com a desconstrução de um pensamento socialmente permeado de dominação masculina e com a árdua construção de um pensamento que vise a igualdade de gênero. O objeto desta pesquisa é o ministério pastoral feminino no contexto batista brasileiro. O texto analisa o discurso das Pastoras Batistas do Estado de São Paulo e o discurso dos líderes da Ordem dos Pastores Batistas de São Paulo (OPBB-SP) a respeito do ministério pastoral feminino e a não filiação de mulheres na OPBB-SP. A importância deste trabalho é a de demostrar as relações de micro poder existentes entre pastores e pastoras e concomitantemente as desigualdades dentro do contexto batista com relação ao ministério pastoral feminino. Essa afirmação se consolida por meio das análises das entrevistas semiestruturadas que realizei na pesquisa de campo, com sete pastoras batistas do Estado de São Paulo, bem como com três líderes da OPPB-SP. Esta é uma pesquisa qualitativa, em que foram analisados documentos oficiais da igreja, como pautas de convenções, atas, sites institucionais, periódicos e documentos não oficiais encontrados em redes sociais, blogs, jornais online, entre outros. Posso afirmar que as pastoras batistas estão se mobilizando para cumprir sua vocação, usando argumentos transcendentes que impedem qualquer pessoa de desafiar ou duvidar de seu chamado pastoral, pois: “O vento sopra onde quer; ouve-se o ruído, mas não sabes de onde vem, nem para onde vai. Assim acontece com aquele(a) que nasceu do Espírito.” (João 3.8).

A study in the application of domestic solar assisted heat pumps for heating and cooling

In the present work, the more important parameters of the heat pump system and of solar assisted heat pump systems were analysed in a quantitative way. Ideal and real Rankine cycles applied to the heat pump, with and without subcooling and superheating were studied using practical recommended values for their thermodynamics parameters. Comparative characteristics of refrigerants here analysed looking for their applicability in heat pumps for domestic heating and their effect in the performance of the system. Curves for the variation of the coefficient of performance as a function of condensing and evaporating temperatures were prepared for R12. Air, water and earth as low-grade heat sources and basic heat pump design factors for integrated heat pumps and thermal stores and for solar assisted heat pump-series, parallel and dual-systems were studied. The analysis of the relative performance of these systems demonstrated that the dual system presents advantages in domestic applications. An account of energy requirements for space and hater heating in the domestic sector in the O.K. is presented. The expected primary energy savings by using heat pumps to provide for the heating demand of the domestic sector was found to be of the order of 7%. The availability of solar energy in the U.K. climatic conditions and the characteristics of the solar radiation here studied. Tables and graphical representations in order to calculate the incident solar radiation over a tilted roof were prepared and are given in this study in section IV. In order to analyse and calculate the heating load for the system, new mathematical and graphical relations were developed in section V. A domestic space and water heating system is described and studied. It comprises three main components: a solar radiation absorber, the normal roof of a house, a split heat pump and a thermal store. A mathematical study of the heat exchange characteristics in the roof structure was done. This permits to evaluate the energy collected by the roof acting as a radiation absorber and its efficiency. An indication of the relative contributions from the three low-grade sources: ambient air, solar boost and heat loss from the house to the roof space during operation is given in section VI, together with the average seasonal performance and the energy saving for a prototype system tested at the University of Aston. The seasonal performance as found to be 2.6 and the energy savings by using the system studied 61%. A new store configuration to reduce wasted heat losses is also discussed in section VI.

Is it all tough talking at the top? A post-structuralist analysis of the construction of gendered speaker identities of British business leaders within interview narratives

This paper uses a feminist post-structuralist approach to examine the gendered identities of a sample of British business leaders in Britain. While recent national surveys offer many material reasons why women are acutely under-represented as business leaders, the role of language is rarely addressed. This paper explores the ways in which ten senior women and men construct their sense of leadership identities through the medium of interview narratives. Drawing upon two poststructuralist models of analysis (Derrida’s 1987 theory of deconstruction and Bakhtin’s 1927/1981 concept of double-voiced discourse), the paper shows how both females and males are able to shift pragmatically between interwoven corporate discourses, which demand competing cultural allegiances from one moment to the next, allegiances constantly tested by the rapid change and uncertainty that characterise global business. While male leaders experience a relative freedom of movement between different cultural discourses, female leaders are circumscribed by negative and reductive representations of female speech and behaviour. In sum, senior women are required constantly to observe, review, police and repair their use of leadership language, which potentially undermines their confidence and authority as leaders.

Constant shear along a boundary of a flume

'I'he accurate rreasurement of bed shear stress has been extremely difficult due to its changing values until white propunded a theory which would give constant shear along the bed of a flume. In this investigation a flume has been designed according to White's theory and by two separate methods proven to give constant shearing force along the bed. The first method applied the Hydrogen Bubble Technique to obtain accurate values of velocity thus allowing the velocity profile to be plotted and the momentum at the various test sections to be calculated. The use of a 16 mm Beaulieu movie camera allowed the exact velocity profiles created by the hydrogen bubbles to be recorded whilst an analysing projector gave the means of calculating the exact velocities at the various test sections. Simultaneously Preston's technique of measuring skin friction using Pitot tubes was applied. Twc banks of open ended water manometer were used for recording the static and velocity head pressure drop along the flume. This tvpe of manometer eliminated air locks in the tubes and was found to be sufficiently accurate. Readings of pressure and velocity were taken for various types and diameters of bed material both natural sands and glass spheres and the results tabulated. Graphs of particle Reynolds Number against bed shear stress were plotted and gave a linear relationship which dropped off at high values of Reynolds number. It was found that bed movement occurred instantaneously along the bed of the flume once critical velocity had been reached. On completion of this test a roof curve inappropriate to the bed material was used and then the test repeated. The bed shearing stress was now no longer constant and yet bed movement started instantaneously along the bed of the flume, showing that there are more parameters than critical shear stress to bed movement. It is concluded from the two separate methods applied that the bed shear stress is constant along the bed of the flume.

Energy conservation measures on an industrial site

World and UK energy resources and use are reviewed and the role of energy conservation in energy policy identified. In considering various energy conservation measures, a distinction is made between energy intensive and non-intensive industries and also between direct and indirect uses of energy. Particular attention is given to the non-intensive user of energy. Energy use on one such industrial site has been studied to determine the most effective energy saving measures in the short term. Here it is estimated that over 65% of energy is consumed for indirect purposes, mainly for heating and lighting buildings. Emphasis is placed on energy auditing techniques and those energy saving measures requiring greater technical, economic and organisational resources to secure their implementation. Energy auditing techniques include the use of aerial thermography and snow formation surveys to detect heat losses. Qualitative and quantitative interpretations are carried out, but restricted mainly to evaluating building roof heat losses. From the energy auditing exercise, it is confirmed that the intermittent heating of buildings is the largest and most cost effective fuel saving measure. This was implemented on the site and a heat monitoring programme established to verify results. Industrial combined heat and power generation is investigated. A proposal for the site demonstrates that there are several obstacles to its successful implementation. By adopting an alternative financial rationale, a way of overcoming these obstacles is suggested. A useful by-product of the study is the classification of industrial sites according to the nature of industrial energy demand patterns. Finally, energy saving measures implemented on the site are quantlfied using comparative verification methods. Overall fuel savings of 13% are indicated. Cumulative savings in heating fuel amount to 26% over four years although heated area increased by approximately 25%.

Stand-alone groundwater desalination system using reverse osmosis combined with a cooled greenhouse for use in arid and semi-arid zones of India

In many areas of northern India, salinity renders groundwater unsuitable for drinking and even for irrigation. Though membrane treatment can be used to remove the salt, there are some drawbacks to this approach e.g. (1) depletion of the groundwater due to over-abstraction, (2) saline contamination of surface water and soil caused by concentrate disposal and (3) high electricity usage. To address these issues, a system is proposed in which a photovoltaic-powered reverse osmosis (RO) system is used to irrigate a greenhouse (GH) in a stand-alone arrangement. The concentrate from the RO is supplied to an evaporative cooling system, thus reducing the volume of the concentrate so that finally it can be evaporated in a pond to solid for safe disposal. Based on typical meteorological data for Delhi, calculations based on mass and energy balance are presented to assess the sizing and cost of the system. It is shown that solar radiation, freshwater output and evapotranspiration demand are readily matched due to the approximately linear relation among these variables. The demand for concentrate varies independently, however, thus favouring the use of a variable recovery arrangement. Though enough water may be harvested from the GH roof to provide year-round irrigation, this would require considerable storage. Some practical options for storage tanks are discussed. An alternative use of rainwater is in misting to reduce peak temperatures in the summer. An example optimised design provides internal temperatures below 30EC (monthly average daily maxima) for 8 months of the year and costs about €36,000 for the whole system with GH floor area of 1000 m2 . Further work is needed to assess technical risks relating to scale-deposition in the membrane and evaporative pads, and to develop a business model that will allow such a project to succeed in the Indian rural context.

Contesting Europe's Eastern Rim:cultural identities in public discourse

Since 1989, Europe's eastern rim has been in constant flux. This collection focuses on how political and economic transformations have triggered redefinitions of cultural identity. Using discursive modes of identity construction (deconstruction, reconstruction, reformulation, and invention) the book focuses on the creation of opposition to old and new outsidersA" and insidersA" in Europe. The linguistic study of discourse elements in connection with an exploration of the significance of metaphors in anchoring individual and collective identity is innovative and allows for a unique analysis of public discourse in Europe.

Essential BIM input data study for housing refurbishment:homeowners’ preferences in the UK

Construction customers are persistently seeking to achieve sustainability and maximize value as sustainability has become a major consideration in the construction industry. In particular, it is essential to refurbish a whole house to achieve the sustainability agenda of 80% CO2 reduction by 2050 as the housing sector accounts for 28% of the total UK CO2 emission. However, whole house refurbishment seems to be challenging due to the highly fragmented nature of construction practice, which makes the integration of diverse information throughout the project lifecycle difficult. Consequently, Building Information Modeling (BIM) is becoming increasingly difficult to ignore in order to manage construction projects in a collaborative manner, although the current uptake of the housing sector is low at 25%. This research aims to investigate homeowners’ decision making factors for housing refurbishment projects and to provide a valuable dataset as an essential input to BIM for such projects. One-hundred and twelve homeowners and 39 construction professionals involved in UK housing refurbishment were surveyed. It was revealed that homeowners value initial cost more while construction professionals value thermal performance. The results supported that homeowners and professionals both considered the first priority to be roof refurbishment. This research revealed that BIM requires a proper BIM dataset and objects for housing refurbishment.

Correlations between garden design plant applications and climate change

Possible effects of climate change means great challenges to landscape design professionals in Hungary. Our climate will shift towards the Mediterranean and we have to prepare for this with among others, choosing correctly the plants to be planted. Teaching garden design dendrology has not recognized yet the necessity and urgency of this matter. Quick measures are required due to the long life-time and slow development of woody taxons. This paper presents the double relationship between landscape design and climate change emphasizing the outdoor architectural methods of adjustment. Such techniques recognized abroad are presented like precipitation drainage by vegetation and extensive green roof. Finally the effects of climate change on ornamental plants application are presented together with the associated project started at the Corvinus University of Budapest in 2010.

Endothelin 3 induces skin pigmentation in a keratin-driven inducible mouse model

Endothelin 3 (Edn3) is a ligand important to developing neural crest cells (NCC). Some NCC eventually migrate into the skin and give rise to the pigment-forming melanocytes found in hair follicles. Edn3's effects on NCC have been largely explored through spontaneous mutants and cell culture experiments. These studies have shown the Endothelin receptor B/Edn3 signaling pathway to be important in the proliferation/survival and differentiation of developing melanocytes. To supplement these investigations I have created doxycycline-responsive transgenic mice which conditionally over-express Edn3. These mice will help us clarify Edn3's role during the development of early embryonic melanoblasts, differentiating melanocyte precursors in the skin, and fully differentiated melanocytes in the hair follicle. The transgene mediated expression of Edn3 was predominantly confined to the roof plate of the neural tube and surface ectoderm in embryos and postnatally in the epidermal keratinocytes of the skin. Relative to littermate controls, transgenics develop increased pigmentation on most areas of the skin. My doxycycline-based temporal studies have shown that both embryonic and postnatal events are important for establishing and maintaining pigmented skin. The study of my Edn3 transgenic mice may offer some insight into the genetics behind benign dermal pigmentation and offer clues about the time periods important in establishing these conditions. This apparently abnormal development is echoed in a benign condition of human skin. Cases of dermal melanocytosis, such as common freckles, Mongolian spotting, and nevus of Ito demonstrate histological and etiological characteristics similar to those of the transgenic mice generated in this study.

The ethical paradigm of Jose Marti's writings beyond Modernity

This dissertation explores the nature of Jose Marti's ethical ideas in relation to the rise of late Nineteenth Century Modernity and in tandem with the deconstruction and subversion of the principal constituencies of colonial and aesthetic discourses. Marti proposes a new paradigm that question the insatiable pursuit of novelty, the hostility towards tradition, the historical perspectivism and a critical stance with regard to social aesthetic Modernity. He also questions the cult of reason, the linear historicism, and the teleological progress framed in philosophical utilitarian pragmatism of bourgeois Modernity. His radical criticism of the structures and institutions of the hegemonic power of the modern state override the ontological and epistemological foundations of Modernity. Marti's deconstruction of the fundamental discourses of euro-centristic Occidental culture leads him, through his ethical writings, to an arqueology of Native American civilizations, thus reinserting, within the false premises of European universalism, his counter-discourse of tradition and the voice of the Other.

Demographic effects of thatch harvest and implications for sustainable use of irapai palm (Lepidocaryum tenue, Mart.), by riverine communities in the Peruvian Amazon

Lepidocaryum tenue Mart. (Arecaceae) is a small, understory palm of terra firme forests of the western and central Amazon basin. Known as irapai, it is used for roof thatch by Amazonian peoples who collect its leaves from the wild and generate income from its fronds and articles fabricated from them. Increasing demand has caused local concern that populations are declining. Cultivation attempts have been unsuccessful. The purpose of this study was to investigate market conditions and quantify population dynamics and demographic responses of harvested and unharvested irapai growing near Iquitos, Peru. ^ Ethnobotanical research included participant surveys to determine movement of thatch tiles, called crisnejas, through Moronacocha Port. I also conducted a seed germination trial, and for four years studied five populations growing in communities with similar topography and soils but different land tenure and management strategies. Stage, survival, leaf production, and reproductive transitions were used to calculate ramet demographic rates and develop population projection matrices. ^ Weavers made an average of 20–30 crisnejas per day (90–130 leaves each), and earned US$0.09 to 0.70 each (US$1.80 to 21.00 per day). Average crisnejas per month sold per vendor was 2,955 with a profit range of US$0.05 to 0.32 per crisneja. Wholesalers worked with capital outlay from US$100 to 400, and an estimated ten to twenty vendors could be found at a given time. Consumers paid between US$0.23 to 1.20 per crisneja. Although differences in demographic rates by location existed, most were not significant enough to attribute to management. ^ After 60 months, mean seed germination rate was 19.5% in all media (37.9% in peat). Seedling survival was less than two percent after twelve months. Annual palm mortality was three percent, and occurred disproportionately in small (<50 cm) palms. Small palms grew more in height. Unharvested palms grew less than harvested palms. Large palms (≥50 cm) produced more leaves, were more likely to reproduce, and collectors harvested them more frequently. Reproductive potentials (sexual and asexual) were low. Population growth rates were greater than or not significantly different from 1.0, indicating populations maintained or increased in size. Current levels of irapai harvest appear sustainable. DNA analysis of stems and recruits is recommended to understand population composition and stage-specific asexual fecundity. ^

Aerodynamic load characteristics evaluation and tri-axial performance testing on fiber reinforced polymer connections and metal fasteners to promote hurricane damage mitigation

Damages during extreme wind events highlight the weaknesses of mechanical fasteners at the roof-to-wall connections in residential timber frame buildings. The allowable capacity of the metal fasteners is based on results of unidirectional component testing that do not simulate realistic tri-axial aerodynamic loading effects. The first objective of this research was to simulate hurricane effects and study hurricane-structure interaction at full-scale, facilitating better understanding of the combined impacts of wind, rain, and debris on inter-component connections at spatial and temporal scales. The second objective was to evaluate the performance of a non-intrusive roof-to-wall connection system using fiber reinforced polymer (FRP) materials and compare its load capacity to the capacity of an existing metal fastener under simulated aerodynamic loads. ^ The Wall of Wind (WoW) testing performed using FRP connections on a one-story gable-roof timber structure instrumented with a variety of sensors, was used to create a database on aerodynamic and aero-hydrodynamic loading on roof-to-wall connections tested under several parameters: angles of attack, wind-turbulence content, internal pressure conditions, with and without effects of rain. Based on the aerodynamic loading results obtained from WoW tests, sets of three force components (tri-axial mean loads) were combined into a series of resultant mean forces, which were used to test the FRP and metal connections in the structures laboratory up to failure. A new component testing system and test protocol were developed for testing fasteners under simulated triaxial loading as opposed to uni-axial loading. The tri-axial and uni-axial test results were compared for hurricane clips. Also, comparison was made between tri-axial load capacity of FRP and metal connections. ^ The research findings demonstrate that the FRP connection is a viable option for use in timber roof-to-wall connection system. Findings also confirm that current testing methods of mechanical fasteners tend to overestimate the actual load capacities of a connector. Additionally, the research also contributes to the development a new testing protocol for fasteners using tri-axial simultaneous loads based on the aerodynamic database obtained from the WoW testing. ^
