GESTÃO DEMOCRÁTICA: O PERFIL IDEOLÓGICO DOS PAIS MEMBROS DO CONSELHO DE ESCOLA

O presente trabalho enfoca a participação e atuação dos pais no Conselho de Escola. Tal participação passou a ser possível após a Constituição de 1988 e a Lei de Diretrizes e Bases da Educação Nacional nº. 9394/96 LDBEN. O estudo tem por objetivo identificar a concepção de participação dos pais membros do Conselho de Escola, e traçar os possíveis perfis ideológicos dos mesmos quanto à gestão escolar. A pesquisa é de natureza empírica, todavia ela se apóia em perfis ideológicos, construídos a partir de análises propiciadas pela Sociologia da Educação e pela Ciência Política. Como referencial teórico apropriamo-nos de Luis Pereira, Juan Bordenave, Maurício Tragtenberg, Edmundo Campos e de C.B. Macpherson. A pesquisa concentrou-se em uma das escolas da Rede Estadual no Município de São Bernardo do Campo SP. Utilizamos métodos de pesquisa de campo e bibliográfica. Além da pesquisa de campo, que teve como base entrevista qualitativa e semi-aberta, realizamos análises das Legislações Federal e Estadual com o objetivo de verificarmos as lacunas existentes na legislação, assim como os limites por ela impostos à participação dos pais na gestão escolar.(AU)

ADOLESCÊNCIA E TRANSTORNO DE CONDUTA: ESTUDO DO FUNCIONAMENTO PSÍQUICO E DA PERCEPÇÃO DA FIGURA PATERNA DE ADOLESCENTES INFRATORES

O presente estudo teve por objetivos: a) investigar conteúdos da psicodinâmica dos adolescentes infratores; b) descrever a percepção das interações afetivo-relacionais dos adolescentes em relação à figura paterna. Para isso foram estudados seis casos de adolescentes que cometeram infração e que cumprem medidas sócioeducativas, sendo cinco deles com 17 anos e um com 14 anos. Esses adolescentes freqüentavam o CEDECA (Centro de Defesa dos Direitos da Criança e do Adolescente) da cidade de Mauá (São Paulo), local onde os dados foram coletados. Foram utilizados como instrumentos o Procedimento de Desenho-Estória com Tema e entrevista semi-estruturada. A aplicação do procedimento foi feita com base nas seguintes instruções: desenhe um adolescente de Mauá e desenhe o pai de um adolescente de Mauá e, após cada desenho, foi pedido que o adolescente contasse uma história sobre o mesmo. De um modo geral, os resultados mostraram que o primitivismo e esteve presente na produção dos seis adolescentes, visto a presença de mecanismos de defesa como idealização, negação, cisão e outros mecanismos de defesa esquizóides. Também ficou evidente que a dificuldade de crescimento e evolução da personalidade, assim como a conduta anti-social estão associadas à qualidade da introjeção da figura paterna e a relação que estes adolescentes estabelecem com ela. Concluiu-se que o modo como se dá o desenvolvimento psíquico é fator determinante para que indivíduo seja levado á conduta delituosa. Por isso, são necessários mais estudos sobre a personalidade de adolescentes em conflito com a lei, para que o conhecimento científico possa contribuir em ações no âmbito familiar, bem como em programas de prevenção primária e secundária que possam dar condições de um bom desenvolvimento psíquico às pessoas antes que cheguem à adolescência e à idade adulta.

ESTRATÉGIAS DE EXPANSÃO DE INSTITUIÇÕES DE ENSINO SUPERIOR PRIVADAS NO BRASIL: ESTUDO DE CASO DO CURSO DE BACHARELADO EM ADMINISTRAÇÃO

A dissertação teve como objetivo principal estudar como uma Instituição de Ensino Superior Privada (IES) atuante no Brasil tem crescido pós Lei de Diretrizes e Bases (LDB) de 1996 até 2015, por meio da análise do curso de bacharelado em Administração de Empresas, nas modalidades: presencial, EAD e Flex (semipresencial). Para este fim, foi realizada uma pesquisa exploratória, de caráter qualitativo baseada no método do estudo de caso. Para coleta de evidências foram analisados relatórios corporativos (Annual Report, Relatórios Internos e outros documentos), entrevistas baseadas em roteiro semiestruturado com gestores da IES privada e observações. Dentre os principais achados, verificou-se que as principais estratégicas de crescimento da IES privada estudada se basearam em fusões e aquisições de outras IES, abertura de novos polos de EAD, na abertura de novas unidades próprias, bem como em inovações em várias dimensões da organização. Os programas governamentais de financiamento aos alunos também são fortes contribuintes para este crescimento, como o Fundo de Financiamento ao Estudante do Ensino Superior (FIES) e o Programa Universidade para Todos (Prouni). Com essa nova realidade, o ensino superior privado recebeu incentivo e facilitação para o seu crescimento, a um ritmo acelerado. Consequentemente pode-se concluir que a IES privada estudada adotou as seguintes estratégias de crescimento: Expansão orgânica com fusões/ aquisições de Instituições menores, com desenvolvimento de planos para todos os campi Brasil; Greenfield (por meio de solicitação de autorização de novas unidades e/ou cursos) em cidades sem possibilidades de aquisições/fusões, e aumentando o número de vagas/ matriculas nas unidades já existentes, aderiu aos programas do governo e também cuidou da evasão por meio de: Seguro educacional; gestão preparada para atender necessidades do discente; Sistema de Ensino com currículos integrados nacionalmente; Intercâmbio de alunos e professores entre as diversas unidades em todas as regiões do país e padronização dos processos.

Chronic illness in non-heterosexual contexts: towards a critical LGBTQ health psychology

In this thesis, I contribute to the expansion of lesbian, gay, bisexual, trans and queer (LGBTQ) psychology by examining chronic illness within non-heterosexual contexts. Chronic illness, beyond the confines of HIV/AIDS, has been a neglected topic in LGBTQ psychology and sexual identity is often overlooked within health psychology. When the health of lesbian, gay and bisexual (LGB) people has been considered there has been an over-reliance on quantitative methods and comparative approaches which seek to compare LGB people?s health to their heterosexual counterparts. In contrast, I adopt a critical perspective and qualitative methods to explore LGBTQ health. My research brings together ideas from LGBTQ psychology and critical health psychology to explore non-heterosexuals? experiences of chronic illness and the discursive contexts within which LGB people live with chronic health conditions. I also highlight the heteronormativity which pervades academic health psychology as well as the „lay? health literature. The research presented in this thesis draws on three different sources of qualitative data: a qualitative online questionnaire (n=190), an online discussion within a newsgroup for people with diabetes, and semi-structured interviews with 20 LGB people with diabetes. These data are analysed using critical realist forms of thematic analysis and discourse analysis. In the first analytic chapter (Chapter 3), I report the perspectives of LGB people living with many different chronic illnesses and how they felt their sexuality shapes their experiences of illness. In Chapter 4, I examine heterosexism within an online discussion and consider the ways in which sexuality is constructed as (ir)relevant to a diabetes support forum. In Chapter 5, I analyse LGB people?s talk about the support family and partners provide in relation to their diabetes and how they negotiate wider discourses of gender, sexuality and individualism. In Chapter 6 I explore how diabetes intersects with gay and bisexual men?s sex lives. In the concluding chapter, I discuss the contributions of my research for a critical LGBTQ health psychology and identify some possible areas for future research.

Addressing the project implementation challenges in the Saudi Arabian power supply industry: an investigative approach towards improving project delivery

For many decades, the Kingdom of Saudi Arabia has been widely known for being a reliable oil exporter. This fact, however, has not exempted it from facing significant domestic energy challenges. One of the most pressing of these challenges involves bridging the widening electricity supply-demand gap where, currently, the demand is growing at a very fast rate. One crucial means to address this challenge is through delivering power supply projects with maximum efficiency. Project delivery delay, however, is not uncommon in this highly capital-intensive industry, indicating electricity supplies are not coping with the demand increases. To provide a deeper insight into the challenges of project implementation and efficient practice, this research adopts a pragmatic approach by triangulating literature, questionnaires and semi-structured interviews. The research was conducted in the Saudi Arabian power supply industry – Western Operating Area. A total of 105 usable questionnaires were collected, and 28 recorded, semi-structured interviews were conducted, analysed and synthesised to produce a conceptual model of what constitutes the project implementation challenges in the investigated industry. This was achieved by conducting a comprehensive ranking analysis applied to all 58 identified and surveyed factors which, according to project practitioners in the investigated industry, contribute to project delay. 28 of these project delay factors were selected as the "most important" ones. Factor Analysis was employed to structure these 28 most important project delay factors into the following meaningful set of 7 project implementation challenges: Saudi Electricity Company's contractual commitments, Saudi Electricity Company's communication and coordination effectiveness, contractors' project planning and project control effectiveness, consultant-related aspects, manpower challenges and material uncertainties, Saudi Electricity Company's tendering system, and lack of project requirements clarity. The study has implications for industry policy in that it provides a coherent assessment of the key project stakeholders' central problems. From this analysis, pragmatic recommendations are proposed that, if enacted, will minimise the significance of the identified problems on future project outcomes, thus helping to ensure the electricity supply-demand gap is diminished.

Optimizing supply chain waste management through the use of RFID technology

This paper presents a Decision Support System framework based on Constrain Logic Programming and offers suggestions for using RFID technology to improve several of the critical procedures involved. This paper suggests that a widely distributed and semi-structured network of waste producing and waste collecting/processing enterprises can improve their planning both by the proposed Decision Support System, but also by implementing RFID technology to update and validate information in a continuous manner. © 2010 IEEE.

Sol–gel derived coating applied to long-period gratings for enhanced refractive index sensing properties

Long-period fibre gratings (LPGs) have previously been used to detect quantities such as temperature, strain, and refractive index (RI). We report here, to the best of our knowledge, the first investigation on refractive index sensing properties of LPGs with sol–gel derived titanium and silicon oxide coatings. It is revealed that the RI sensitivity of an LPG is affected by both the thickness and the index value of the coating; a coating with higher index and thickness will enhance the LPG RI sensitivity significantly. The surrounding refractive index induced LPG resonance shift has been evaluated over the LPGs' most sensitive RI region from 1.42 to 1.44. We have identified that, in this region, the uncoated LPG has an RI sensitivity of (-673.0 ± 0.4) nm/uri (unit of refractive index) while the LPG coated with titanium oxide exhibits a sensitivity as high as (-1067.15 ± 0.04) nm/uri. The experimental results also reveal that, even in the RI insensitive region around 1.33, there still is a marked enhancement in RI sensitivity of the sol–gel coated LPG compared to the uncoated one. This is potentially significant as coated LPGs may be extended to low RI gas and semi-liquidized based sensing applications.

Novel hydrogel polymers

Hydrogels may be conveniently described as hydrophilic polymers that are swollen by, but do not dissolve in water. In this work a series of copolymer hydrogels and semi-interpenetrating polymer networks based on the monomers 2-hydroxyethyl methacrylate, N-vinyl pyrrolidone and N'N' dimethyl acrylamide, together with some less hydrophilic hydroxyalkyl acrylates and methacrylates have been synthesised. Variations in structure and composition have been correlated both with the total equilibrium water content of the resultant hydrogel and with the more detailed water binding behaviour, as revealed by differential scanning calorimetry studies. The water binding characteristics of the hydrogels were found to be primarily a function of the water structuring groups present in gel. The water binding abilities of these groups were, however, modified by steric effects. The mechanical properties of the hydrogels were also investigated. These were found to be dependent on both the polymer composition and the amount and nature of the water present in the gels. In biological systems, composite formation provides a means of producing strong, high water content materials. As an analogy with these systems hydrogel composites were prepared. In an initial study of these materials the water binding and mechanical properties of semi-interpenetrating polymer networks of N'N'dimethyl acrylamide with cellulosic type materials, with polyurethanes and with ester containing polymers were examined. A preliminary investigation of surface properties of both the copolymers and semi-interpenetrating polymer networks has been completed, using both contact angle measurements and anchorage dependent fibroblast cells. Measurable differences in surface properties attributable to structural variations in the polymers were detected by droplet techniques in the dehydrated state. However, in the hydrated state these differences were masked by the water in the gels. The use of cells enabled the underlying differences to be probed and the nature of the water structuring group was again found to be the dominant factor.

The morphology of spray-dried particles

Samples of Various industrial or pilot plant spray-dried materials were obtained from manufacturers together with details of drying conditions and feed concentrations. The samples were subjected to qualitative and semi-quantitative examination to identify structural and morphological features. The results were related to measured bulk physical properties and to drying conditions. Single particles were produced in a convective drying process Analogous to spray drying, in which different solids or mixtures of solids were dried from solutions, slurries or pastes as single suspended droplets. The localized chemical and physical structures were analysed and in some cases the retention of volatiles monitored. The results were related to experimental conditions, viz.; air temperature, initial solids concentration and the degree of feed aeration. Three distinct categories of particle morphology were identified, i.e.; crystalline, skin-forming and agglomerate. Each category is evidence of a characteristic drying behaviour which is dependent on initial solids concentration. the degree of feed aeration, and drying temperature. Powder flow ability, particle and bulk density, particle-size, particle friability, and the retention of volatiles bear a direct relationship to morphological structure. Morphologies of multicomponent mixtures were complex, but the respective migration rates of the solutes were dependent on drying temperature. Gas-film heat and SDSS transfer coefficients of single pure liquid droplets were also measured over a temperature range of 50•C to 200•C under forced convection. Balanced transfer rates were obtained attributed to droplet instability or oscillation within the airflow, demonstrated in associated work with single free-flight droplets. The results are of relevance to drier optimisation and to the optimisation of product characteristics, e.g.; particle strength and essential volatiles-retention, in convective drying.

An analysis of the effectiveness of a behavioural based safety intervention in a UK paper mill

This research examines a behavioural based safety (BBS) intervention within a paper mill in the South East of England. Further to this intervention two other mills are examined for the purposes of comparison — one an established BBS programme and the other an improving safety management system through management ownership. BBS programmes have become popular within the UK, but most of the research about their efficacy is carried out by the BBS providers themselves. This thesis aims to evaluate a BBS intervention from a standpoint which is not commercially biased in favour of BBS schemes. The aim of a BBS scheme is to either change personnel behaviours or attitudes, which in turn will positively affect the organisation's safety culture. The research framework involved a qualitative methodology in order to examine the effects of the intervention on the paper mill's safety culture. The techniques used were questionnaires and semi structured interviews, in addition to observation and discussions which were possible because of the author's position as participant observer. The results demonstrated a failure to improve any aspect of the mill's safety culture, which worsened following the BBS intervention. Issues such as trust, morale, communication and support of management showed significant signs of negative workforce response. The paper mill where the safety management system approach was utilised demonstrated a significantly improved safety culture and achieved site ownership from middle managers and supervisors. Research has demonstrated that a solid foundation is required prior to successfully implementing a BBS programme. For a programme to work there must be middle management support in addition to senior management commitment. If a trade union actively distances itself from BBS, it is also unlikely to be effective. This thesis proposes that BBS observation programmes are not suitable for the papermaking industry, particularly when staffing levels are low due to challenging economic conditions. Observers are not available when there are high hazard situations and this suggests that BBS implementation is not the correct intervention for the paper industry.

Computer interpretation of engineering drawings as solid models

Much of the geometrical data relating to engineering components and assemblies is stored in the form of orthographic views, either on paper or computer files. For various engineering applications, however, it is necessary to describe objects in formal geometric modelling terms. The work reported in this thesis is concerned with the development and implementation of concepts and algorithms for the automatic interpretation of orthographic views as solid models. The various rules and conventions associated with engineering drawings are reviewed and several geometric modelling representations are briefly examined. A review of existing techniques for the automatic, and semi-automatic, interpretation of engineering drawings as solid models is given. A new theoretical approach is then presented and discussed. The author shows how the implementation of such an approach for uniform thickness objects may be extended to more general objects by introducing the concept of `approximation models'. Means by which the quality of the transformations is monitored, are also described. Detailed descriptions of the interpretation algorithms and the software package that were developed for this project are given. The process is then illustrated by a number of practical examples. Finally, the thesis concludes that, using the techniques developed, a substantial percentage of drawings of engineering components could be converted into geometric models with a specific degree of accuracy. This degree is indicative of the suitability of the model for a particular application. Further work on important details is required before a commercially acceptable package is produced.

Verification of the standard model of the photorefractive nonlinearity in BSO crystals

On the basis of the standard model for the photorefractive nonlinearity we investigate whether a systematic description of the dependence of two-beam energy exchange on beam polarization and grating vector K is possible. Our result is that there is good agreement between theory and experiment with respect to the polarization properties and semi-quantitative agreement with respect to the K-dependence of the energy exchange.

Modelling nonlinear stochastic dynamics in financial time series

For analysing financial time series two main opposing viewpoints exist, either capital markets are completely stochastic and therefore prices follow a random walk, or they are deterministic and consequently predictable. For each of these views a great variety of tools exist with which it can be tried to confirm the hypotheses. Unfortunately, these methods are not well suited for dealing with data characterised in part by both paradigms. This thesis investigates these two approaches in order to model the behaviour of financial time series. In the deterministic framework methods are used to characterise the dimensionality of embedded financial data. The stochastic approach includes here an estimation of the unconditioned and conditional return distributions using parametric, non- and semi-parametric density estimation techniques. Finally, it will be shown how elements from these two approaches could be combined to achieve a more realistic model for financial time series.

Dissipative nonlinear structures in optical fiber systems I : dissipative dispersion managed solitons in mode-locked lasers

In this first talk on dissipative structures in fiber applications, we extend theory of dispersion-managed solitons to dissipative systems with a focus on mode-locked fibre lasers. Dissipative structures exist at high map strengths leading to the generation of stable, short pulses with high energy. Two types of intra-map pulse evolutions are observed depending on the net cavity dispersion. These are characterized by a reduced model and semi-analytical solutions are obtained.

Can incident reporting improve safety? Healthcare practitioners' views of the effectiveness of incident reporting

OBJECTIVE: Recent critiques of incident reporting suggest that its role in managing safety has been over emphasized. The objective of this study was to examine the perceived effectiveness of incident reporting in improving safety in mental health and acute hospital settings by asking staff about their perceptions and experiences. DESIGN: /st>Qualitative research design using documentary analysis and semi-structured interviews. SETTING: /st>Two large teaching hospitals in London; one providing acute and the other mental healthcare. PARTICIPANTS: /st>Sixty-two healthcare practitioners with experience of reporting and analysing incidents. RESULTS: /st>Incident reporting was perceived as having a positive effect on safety, not only by leading to changes in care processes but also by changing staff attitudes and knowledge. Staff discussed examples of both instrumental and conceptual uses of the knowledge generated by incident reports. There are difficulties in using incident reports to improve safety in healthcare at all stages of the incident reporting process. Differences in the risks encountered and the organizational systems developed in the two hospitals to review reported incidents could be linked to the differences we found in attitudes to incident reporting between the two hospitals. CONCLUSION: /st>Incident reporting can be a powerful tool for developing and maintaining an awareness of risks in healthcare practice. Using incident reports to improve care is challenging and the study highlighted the complexities involved and the difficulties faced by staff in learning from incident data.
