Órgão de governação de topo do hospital público português : estrutura e constituição

RESUMO - Pretende-se com este projecto fazer uma reflexão sobre a problemática dos modelos de governação na gestão pública de hospitais e sobre a forma de incrementar a capacidade estratégica da gestão, contextualizando a governação dos hospitais num quadro mais amplo e comunitário, integrando os interesses e expectativas dos diversos interessados no funcionamento dos hospitais públicos. Sinteticamente, a questão fundamental de investigação é: Como conseguirá o sistema de governação de um hospital público incorporar os interesses de todos os seus stakeholders e shareholders? A resposta a esta questão integra duas fases, uma primeira dedicada ao estudo de um novo modelo de configuração para o órgão de governação de topo do hospital público e uma segunda fase dedicada à construção de um questionário para discussão e validação do modelo proposto através da técnica Delphi. A metodologia utilizada passou pela condução prévia de entrevistas exploratórias a informadores privilegiados e pela divisão do projecto em duas partes – uma primeira parte de enquadramento que segue a metodologia clássica da revisão bibliográfica e uma segunda parte prática que segue a metodologia Delphi, precedida de um levantamento das questões críticas para integrar no questionário que servirá de base à discussão dos peritos. Como resultado, o actual modelo pareceu-nos dificultar a consideração das expectativas e dos interesses dos proprietários/accionistas e dos stakeholders em geral do hospital público, concluindo-se pela necessidade de um novo modelo que estabeleça, inequivocamente, os papéis e as funções inerentes ao órgão de governação, garantindo a internalização da perspectiva de todos os interessados. -------------------------------ABSTRACT - The objective of this project is to reflect on the problematic of models of governance in the public management of hospitals and on the means for incrementing strategic management capacity. It does so by contextualizing the governance of public hospitals on a more ample community–wide scale, integrating the interests and expectations of different parties. The main research question is: how can the system of governance of a public hospital incorporate the interests of all its stakeholders and shareholders? The answer to this question involves two phases, one dedicated to the study of the configuration of the top-level governing body of the public hospital and, a second, dedicated to the construction of a questionnaire for discussion and validation of the proposed model by means of a Delphi technique. The methodology involved, first of all, exploratory interviews with key- informants and by the structuring of the project in two parts – the first, dedicated to contextualization by means of a standard literature review and the second, essentially practical by means of the Delphi technique, preceded by the raising of critical questions that integrate the questionnaire that will form the basis of expert discussion. The present model of public hospital governance appears to limit the possibility of integrating the expectations and interests of stakeholders and owner/shareholders. It is concluded that a new model is needed, one that establishes unequivocally the roles and functions of the top- level governing body, thereby

Cell functional enviromics: applications to Pichia pastoris

The present PhD thesis develops the cell functional enviromics (CFE) method to investigate the relationship between environment and cellular physiology. CFE may be defined as the envirome-wide cellular function reconstruction through the collection and systems-level analysis of dynamic envirome data. Throughout the thesis, CFE is illustrated by two main applications to cultures of a constitutive P. pastoris X33 strain expressing a scFv antibody fragment. The first application addresses the challenge of culture media development. A dataset was built from 26 shake flask experiments, with variations in trace elements concentrations and basal medium dilution based on the standard BSM+PTM1. Protein yield showed high sensitivity to culture medium variations, while biomass was essentially determined by BSM dilution. High scFv yield was associated with high overall metabolic fluxes through central carbon pathways concomitantly with a relative shift of carbon flux from biosynthetic towards energy-generating pathways. CFE identified three cellular functions (growth, energy generation and by-product formation) that together described 98.8% of the variance in observed fluxes. Analyses of how medium factors relate to identified cellular functions showed iron and manganese at concentrations close to PTM1 inhibit overall metabolic activity. The second application addresses bioreactor operation. Pilot 50 L fed-batch cultivations, followed by 1H-NMR exometabolite profiling, allowed the acquisition of data for 21 environmental factors over time. CFE identified five major metabolic pathway groups that are frequently activated by the environment. The resulting functional enviromics map may serve as template for future optimization of media composition and feeding strategies for Pichia pastoris. The present PhD thesis is a step forward towards establishing the foundations of CFE that is still at its infancy. The methods developed herein are a contribution for changing the culture media and process development paradigm towards a holistic and systematic discipline in the future.

SENSITIVITY ANALYSIS OF TRACK VIBRATIONS DUE TO VERTICAL STIFFNESS VARIATION IN HIGH-SPEED RAILWAYS

High speed trains, when crossing regions with abrupt changes in vertical stiffness of the track and/or subsoil, may generate excessive ground and track vibrations. There is an urgent need for specific analyses of this problem so as to allow reliable esimates of vibration amplitude. Full understanding of these phenomena will lead to new construction solutions and mitigation of undesirable features. In this paper analytical transient solutions of dynamic response of one-dimensional systems with sudden change of foundation stiffness are derived. Results are expressed in terms of vertical displacement. Sensitivity analysis of the response amplitude is also performed. The analytical expressions presented herein, to the authors’ knowledge, have not been published yet. Although related to one-dimensional cases, they can give useful insight into the problem. Nevertheless, in order to obtain realistic response, vehicle- rail interaction cannot be omitted. Results and conclusions are confirmed using general purpose commercial software ANSYS. In conclusion, this work contributes to a better understanding of the additional vibration phenomenon due to vertical stiffness variation, permitting better control of the train velocity and optimization of the track design.
