Assessing the PhD: a constructive view of criteria

Research and informed debate reveals that institutional practices in relation to research degree examining vary considerably across the sector. Within a context of accountability and quality assurance/total quality management, the range and specificity of criteria that are used to judge doctoral work is of particular relevance. First, a review of the literature indicates that, although interest in and concern about the process is burgeoning, there is little empirical research published from which practitioners can draw guidance. The second part of the paper reviews that available research, drawing conclusions about issues that seem to pertain at a general level across disciplines and institutions. Lest the variation is an artefact of discipline difference, the third part of the paper focuses on a within discipline study. Criteria expected/predicted by supervisors are compared and contrasted with those anticipated and experienced by candidates and with those implemented and considered important by examiners. The results are disturbing.

Development-led archaeology in north-west Europe

Many countries in northern Europe have seen a huge expansion in development-led archaeology over the past few decades. Legislation, frameworks for heritage management and codes of practice have developed along similar but different lines. The Valetta Convention has had considerable impact on spatial planning and new legislation on archaeological heritage management within EC countries as well as on the funding, nature and distribution of archaeological fieldwork. For the first time these 12 papers bring together data on developer-led archaeology in Britain, Ireland, France, the Low Countries, Germany and Denmark in order to review and evaluate key common issues relating to organisation, practice, legal frameworks and quality management.

On identity reformation and local transition: a case from Poland

Purpose – The purpose of this paper is to explore and understand the process of successful introduction of total quality management (TQM) in Poland and the way in which it impacted on identity of Polish managers. Design/methodology/approach – The study is based on a combination of ethnographic research and repertory grid interviews. Findings – The process of TQM introduction and implementation is examined through the application of translation as a model incorporating cultural and socio-economical dimensions in addition to individual and organizational levels that shaped the development of TQM in Poland. It then draws on the idea of fantasy as theorized in Lacanian psychoanalysis in order to incorporate the unconscious element of translation process which is missing from Latour’s theorization and which forms an important aspect of adoption of new technology and the emergence of a new post-transition generation of managers in Poland. The paper argues that a complex combination of contextual factors, amongst them the notion of fantasy shaped the process of translation of TQM to Poland, the identity formation of Polish managers and to the emergence of a new post-transition generation of managers in Poland. Originality/value – This paper contributes to the literature on the post-command transition by illustrating this process through the fantasy of total quality management explored in a specific socio-cultural and geographical context and by combining the idea of Latour’s translation with Lacanian fantasy.

Arachidonic acid actions on functional integrity and attenuation of the negative effects of palmitic acid in a clonal pancreatic beta-cell line

Chronic exposure of pancreatic beta-cells to saturated non-esterified fatty acids can lead to inhibition of insulin secretion and apoptosis. Several previous studies have demonstrated that saturated fatty acids such as PA (palmitic acid) are detrimental to beta-cell function compared with unsaturated fatty acids. In the present study, we describe the effect of the polyunsaturated AA (arachidonic acid) on the function of the clonal pancreatic beta-cell line BRIN-BD11 and demonstrate AA-dependent attenuation of PA effects. When added to beta-cell incubations at 100 mu M, AA can stimulate cell proliferation and chronic (24 h) basal insulin secretion. Microarray analysis and/or real-time PCR indicated significant AA-dependent up-regulation of genes involved in proliferation and fatty acid metabolism [e.g. Angptl (angiopoietin-like protein 4), Ech1 (peroxisomal Delta(3.5),Delta(2.4)-dienoyl-CoA isomerase), Cox-1 (cyclo-oxygenase-1) and Cox-2, P < 0.05]. Experiments using specific COX and LOX (lipoxygenase) inhibitors demonstrated the importance of COX-1 activity for acute (20 min) stimulation of insulin secretion, suggesting that AA metabolites may be responsible for the insulinotropic effects. Moreover, concomitant incubation of AA with PA dose-dependently attenuated the detrimental effects of the saturated fatty acid, so reducing apoptosis and decreasing parameters of oxidative stress [ROS (reactive oxygen species) and NO levels] while improving the GSH/GSSG ratio. AA decreased the protein expression of iNOS (inducible NO synthase), the p65 subunit of NF-kappa B (nuclear factor kappa B) and the p47 subunit of NADPH oxidase in PA-treated cells. These findings indicate that AA has an important regulatory and protective beta-cell action, which may be beneficial to function and survival in the `lipotoxic` environment commonly associated with Type 2 diabetes mellitus.

Stochastic Assessment Of Environmental Flows In Semiarid Environments

The regimen of environmental flows (EF) must be included as terms of environmental demand in the management of water resources. Even though there are numerous methods for the computation of EF, the criteria applied at different steps in the calculation process are quite subjective whereas the results are fixed values that must be meet by water planners. This study presents a friendly-user tool for the assessment of the probability of compliance of a certain EF scenario with the natural regimen in a semiarid area in southern Spain. 250 replications of a 25-yr period of different hydrological variables (rainfall, minimum and maximum flows, ...) were obtained at the study site from the combination of Monte Carlo technique and local hydrological relationships. Several assumptions are made such as the independence of annual rainfall from year to year and the variability of occurrence of the meteorological agents, mainly precipitation as the main source of uncertainty. Inputs to the tool are easily selected from a first menu and comprise measured rainfall data, EF values and the hydrological relationships for at least a 20-yr period. The outputs are the probabilities of compliance of the different components of the EF for the study period. From this, local optimization can be applied to establish EF components with a certain level of compliance in the study period. Different options for graphic output and analysis of results are included in terms of graphs and tables in several formats. This methodology turned out to be a useful tool for the implementation of an uncertainty analysis within the scope of environmental flows in water management and allowed the simulation of the impacts of several water resource development scenarios in the study site.

Comparison Of Demand Pattern Calibration In Water Distribution Networks With Geographic And Non-Geographic Parameterization

Demands are one of the most uncertain parameters in a water distribution network model. A good calibration of the model demands leads to better solutions when using the model for any purpose. A demand pattern calibration methodology that uses a priori information has been developed for calibrating the behaviour of demand groups. Generally, the behaviours of demands in cities are mixed all over the network, contrary to smaller villages where demands are clearly sectorised in residential neighbourhoods, commercial zones and industrial sectors. Demand pattern calibration has a final use for leakage detection and isolation. Detecting a leakage in a pattern that covers nodes spread all over the network makes the isolation unfeasible. Besides, demands in the same zone may be more similar due to the common pressure of the area rather than for the type of contract. For this reason, the demand pattern calibration methodology is applied to a real network with synthetic non-geographic demands for calibrating geographic demand patterns. The results are compared with a previous work where the calibrated patterns were also non-geographic.

A Diagnostic Assessment Of Evolutionary Multiobjective Optimization For Water Resources Systems

This study contributes a rigorous diagnostic assessment of state-of-the-art multiobjective evolutionary algorithms (MOEAs) and highlights key advances that the water resources field can exploit to better discover the critical tradeoffs constraining our systems. This study provides the most comprehensive diagnostic assessment of MOEAs for water resources to date, exploiting more than 100,000 MOEA runs and trillions of design evaluations. The diagnostic assessment measures the effectiveness, efficiency, reliability, and controllability of ten benchmark MOEAs for a representative suite of water resources applications addressing rainfall-runoff calibration, long-term groundwater monitoring (LTM), and risk-based water supply portfolio planning. The suite of problems encompasses a range of challenging problem properties including (1) many-objective formulations with 4 or more objectives, (2) multi-modality (or false optima), (3) nonlinearity, (4) discreteness, (5) severe constraints, (6) stochastic objectives, and (7) non-separability (also called epistasis). The applications are representative of the dominant problem classes that have shaped the history of MOEAs in water resources and that will be dominant foci in the future. Recommendations are provided for which modern MOEAs should serve as tools and benchmarks in the future water resources literature.

Análise crítica de um método para implementação das normas ISO 9000 em pequenas e médias empresas brasileiras

Esta dissertação apresenta a análise crítica da aplicação de um método utilizado para implementação da Norma ISO Série 9000. Este método, denominado Bremen Quality Management (BQM), foi desenvolvido na Alemanha, onde vem sendo utilizado com sucesso junto a pequenas e médias empresas (PMEs). O objetivo principal do presente trabalho é analisar se este método também é adequado às necessidades das PMEs brasileiras. O trabalho inicia-se com uma revisão bibliográfica destinada a identificar as dificuldades enfrentadas pelas PMEs durante o processo de implementação da ISO 9000. Foram estudados também métodos potencialmente comparáveis ao BQM utilizados por algumas instituições atuantes na área dos Sistemas da Qualidade, tais como SEBRAE-RS e FUNDATEC-RS. Devido a uma questão de segredo comercial, a especificação formal do Método BQM não se encontra publicamente acessível, pelo que, num segundo momento, foi necessário reunir as informações disponíveis sobre o mesmo de modo a possibilitar a construção de documentação relacionada com a sua formalização. A análise do Método BQM foi realizada a partir da implementação da NBR ISO 9001 em uma empresa de médio porte localizada no Estado do Rio Grande do Sul, utilizando-se para isso a pesquisa participante.A sua implementaçãofoi possível devido à inclusãodessa empresa,bem como da UniversidadeFederaldo Rio Grandedo Sul, num projeto de pesquisa gerenciadopela instituiçãoestrangeiraque criouo MétodoBQM. Pela análise realizada, pode-se constatar que, apesar das oportunidades de melhorias identificadas, o método BQM pode auxiliar as PMEs brasileiras na implementação da ISO 9000. Por fim, são propostas alterações no método estudado, com a finalidade de melhorar a sua adequação às necessidades das PMEs brasileiras.

Uma proposta de arquitetura de linha de produto para sistemas de gerenciamento de workflow

A tecnologia de workflow vem apresentando um grande crescimento nos últimos anos. Os Workflow Management Systems (WfMS) ou Sistemas de Gerenciamento de Workflow oferecem uma abordagem sistemática para uniformizar, automatizar e gerenciar os processos de negócios. Esta tecnologia requer técnicas de engenharia de software que facilitem a construção desse tipo de sistema. Há muito vem se formando uma consciência em engenharia de software de que para a obtenção de produtos com alta qualidade e que sejam economicamente viáveis torna-se necessário um conjunto sistemático de processos, técnicas e ferramentas. A reutilização está entre as técnicas mais relevantes desse conjunto. Parte-se do princípio que, reutilizando partes bem especificadas, desenvolvidas e testadas, pode-se construir software em menor tempo e com maior confiabilidade. Muitas técnicas que favorecem a reutilização têm sido propostas ao longo dos últimos anos. Entre estas técnicas estão: engenharia de domínio, frameworks, padrões, arquitetura de software e desenvolvimento baseado em componentes. Porém, o que falta nesse contexto é uma maneira sistemática e previsível de realizar a reutilização. Assim, o enfoque de linha de produto de software surge como uma proposta sistemática de desenvolvimento de software, baseada em uma família de produtos que compartilham um conjunto gerenciado de características entre seus principais artefatos. Estes artefatos incluem uma arquitetura base e um conjunto de componentes comuns para preencher esta arquitetura. O projeto de uma arquitetura para uma família de produtos deve considerar as semelhanças e variabilidades entre os produtos desta família. Esta dissertação apresenta uma proposta de arquitetura de linha de produto para sistemas de gerenciamento de workflow. Esta arquitetura pode ser usada para facilitar o processo de produção de diferentes sistemas de gerenciamento de workflow que possuem características comuns, mas que também possuam aspectos diferentes de acordo com as necessidades da indústria. O desenvolvimento da arquitetura proposta tomou como base a arquitetura genérica e o modelo de referência da Workflow Management Coalition (WfMC) e o padrão de arquitetura Process Manager desenvolvido no contexto do projeto ExPSEE1. O processo de desenvolvimento da arquitetura seguiu o processo sugerido pelo Catalysis com algumas modificações para representar variabilidade. A arquitetura proposta foi descrita e simulada através da ADL (Architecture Description Language) Rapide. A principal contribuição deste trabalho é uma arquitetura de linha de produto para sistemas de gerenciamento de workflow. Pode-se destacar também contribuições para uma proposta de sistematização de um processo de desenvolvimento de arquitetura de linha de produto e também um melhor entendimento dos conceitos e abordagens relacionados à prática de linha de produto, uma vez que esta tecnologia é recente e vem sendo largamente aplicada nas empresas.
