What factors of satisfaction and motivation are affecting the development of the academic career in Portuguese higher education institutions?

An important constituent group and a key resource of higher education institutions (HEIs) is the faculty or academic staff. The centrality of the faculty role makes it a primary sculptor of institutional culture and has implications for the quality of the institution and therefore has a major role in achieving the objectives of the institution. Demand for academic staff in higher education has been increasing and may be expected to continue to increase. Moreover the performance of academic staff as teachers and researchers determines much of the student satisfaction and has an impact on student learning. There are many factors that serve to undermine the commitment of academics to their institutions and careers. Job satisfaction is important in revitalizing staff motivation and in keeping their enthusiasm alive. Well motivated academic staff can, with appropriate support, build a national and international reputation for themselves and the institution in the professional areas, in research and in publishing. This paper aims to identify the issues and their impacts on academic staff job satisfaction and motivation within Portuguese higher education institutions reporting an ongoing study financed by the European Union through the Portuguese Foundation for Science and Technology.

A practical approach for profit-based unit commitment with emission limitations

This paper proposes a practical approach for profit-based unit commitment (PBUC) with emission limitations. Under deregulation, unit commitment has evolved from a minimum-cost optimisation problem to a profit-based optimisation problem. However, as a consequence of growing environmental concern, the impact of fossil-fuelled power plants must be considered, giving rise to emission limitations. The simultaneous address of the profit with the emission is taken into account in our practical approach by a multiobjective optimisation (MO) problem. Hence, trade-off Curves between profit and emission are obtained for different energy price profiles, in a way to aid decision-makers concerning emission allowance trading. Moreover, a new parameter is presented, ratio of change, and the corresponding gradient angle, enabling the proper selection of a compromise commitment for the units. A case study based on the standard IEEE 30-bus system is presented to illustrate the proficiency Of Our practical approach for the new competitive and environmentally constrained electricity supply industry.

Unit Commitment in a Competitive and Emission Constrained Environment

This paper is on the unit commitment problem, considering not only the economic perspective, but also the environmental perspective. We propose a bi-objective approach to handle the problem with conflicting profit and emission objectives. Numerical results based on the standard IEEE 30-bus test system illustrate the proficiency of the proposed approach.

Optimization model for medium term natural gas commitment

In this paper we study the optimal natural gas commitment for a known demand scenario. This study implies the best location of GSUs to supply all demands and the optimal allocation from sources to gas loads, through an appropriate transportation mode, in order to minimize total system costs. Our emphasis is on the formulation and use of a suitable optimization model, reflecting real-world operations and the constraints of natural gas systems. The mathematical model is based on a Lagrangean heuristic, using the Lagrangean relaxation, an efficient approach to solve the problem. Computational results are presented for Iberian and American natural gas systems, geographically organized in 65 and 88 load nodes, respectively. The location model results, supported by the computational application GasView, show the optimal location and allocation solution, system total costs and suggest a suitable gas transportation mode, presented in both numerical and graphic supports.

Peculiarities of the professional education and qualification appraisal of assistants of pharmacists in Lithuania

Following the alterations and additions to the pharmaceutical law of Lithuanian Republic the pharmaceutical activity in Lithuanian pharmacies is carried out by pharmacy specialists – pharmacists and pharmacy assistants (pharmacy technicians). The ability of pharmacy specialists to adapt, to improve and to develop their competencies is one of the success preconditions for Lithuanian health care pharmacy sector. Work aim: to investigate the changes among the specialists employed in pharmacies and pharmacy sector as well as to highlight the necessity to develop the qualification of pharmacy assistants (pharmacy technicians) according to the modern pharmaceutical legal basis in Lithuania. In 2008–2011 the research in Lithuanian pharmacy sector was performed which identified the changes in the numbers of pharmacies and their staff: the number of pharmacies decreased, while the number of pharmacists increased and the number of the assistants of pharmacists (pharmacy technicians) decreased. The decrease in the number of the assistants of pharmacists (pharmacy technicians) and the danger of their extinction in the future has been identified. The qualification appraisal for pharmacy assistants (pharmacy technicians) is implemented through the leveling studies at the Pharmacy technique department at the Health care faculty of Kauno Kolegija University of applied sciences and pharmacy study programme at the faculty of Pharmacy of Medical Academy at Lithuanian University of Health Sciences. 75 % of respondents use their own money to pay for the qualification appraisal, and 25 % of respondents get financial support for the qualification appraisal activities from the pharmacy managers.

Accounting logic and new professional in healthcare: a case study

The central place hospitals occupy in health systems transforms them into prime target of healthcare reforms. This study aims to identify current trends in organizational structure change in public hospitals and explore the role of accounting in attempts to develop controls over professionals within public hospitals. The analytical framework we proposed crosses the concept of “new professionalism” (Evetts, 2010), with the concept of “accounting logic” for controlling professionals (Broadbent and Laughlin, 1995). Looking for a more holistic overview, we developed a qualitative and exploratory study. The data were collected trough semi-structured interviews with doctors of a clinical hospital unit. Content analysis suggests that, although we cannot say that there is a complete and generalized integration of accounting information in the clinical decisions, important improvement has been made in that area. Despite the extensive literature developed on this topic, there is any empirical studies of authors are aware that allow us to realize how real doctors in reals day-to-day work integrated these trends of change in theirs clinical decisions.

Public relations, satisfaction and commitment

The importance of the organizational relationship (senior managers) with an internal public (employees) is the main focus of this research, aiming to understand how this relationship differs between the different publics. Nowadays, the relevance attributed by Public Relations to this relationship is crucial. The main purpose is to identify two consistent models to measure the impact of an organizational relationship on the internal public. The second purpose is to identify how the internal public react to this organizational relationship, namely by gender. The research was conducted in nine Portuguese companies with a sample of 1.244 subjects in order to study the context of the relationship and validate the identified models. The results show the gender stereotypes in the relationship in these companies and that the organizational relationship has an impact on organizational commitment with a consistent model that highlights the impact of Public Relations on a company's productivity.

Modelo de competências dos enfermeiros com funções de gestão em Portugal: estudo exploratório

Nas últimas décadas assistimos a transformações económicas, tecnológicas, políticas e sociais, que influenciaram diretamente o modo de pensar e agir nas organizações. O conceito de competências, com uma valorização crescente, surge como uma alternativa à abordagem da gestão de recursos humanos por funções, respondendo aos desafios atuais do mercado: necessidade de flexibilidade, de adaptação a mudanças contínuas, exigências crescentes do mercado e competitividade das organizações nesse mercado. A área da saúde, e concretamente a profissão de Enfermagem também tem evoluído, surgindo em 2009, uma nova forma de operacionalizar a carreira destes profissionais. No que diz respeito aos enfermeiros com funções de gestão, o conteúdo funcional está descrito, contudo, não existe uma definição clara das competências requeridas para estes profissionais. Este trabalho de investigação, de cariz exploratório, utilizando uma metodologia qualitativa, pretendeu propor uma estratégia de definição de um modelo de competências para os enfermeiros com funções de gestão em Portugal. Para isso, definimos categorias de competências, através da análise da literatura e da legislação. Seguiu-se a realização de entrevistas a um painel de doze peritos, e uma análise de conteúdo dos dados (categorização do tipo misto). Procedemos a uma comparação da recolha empírica de competências com as da recolha teórica, e definimos uma lista de 10 competências para as funções de gestão dos enfermeiros: Competências Técnicas de Gestão; Competências Interpessoais; Comunicação; Gestão de Recursos Humanos; Pensamento Crítico; Conhecimento de Políticas de Saúde; Competências Técnicas de Enfermagem; Organização e Planeamento; Trabalho de Equipa; Preocupação pela Qualidade. De forma a complementar o estudo, pretendemos identificar a perceção das lacunas de competências nos enfermeiros com funções de gestão, e identificar os processos de desenvolvimento de competências considerados mais relevantes para estes profissionais. As lacunas identificadas nas competências dos atuais enfermeiros com funções de gestão, face às mais valorizadas, são reduzidas e dispersas, pelo que consideramos pouco significativas. A forma de desenvolvimento de competências mais valorizado pelo painel de peritos foi a formação (académica e em contexto profissional). Foi também realçada a importância do empenho individual neste processo, assim como a avaliação de competências antes dos enfermeiros assumirem funções de gestão.Consideramos que esta investigação traz contributos quer para a literatura da Gestão por Competências, quer para a literatura da definição de competências das funções dos enfermeiros com funções de gestão, quer para a profissão de enfermagem, (nomeadamente, para as funções de gestão dos enfermeiros), quer para o próprio SNS, já que faz algumas propostas e sugestões para a evolução das práticas de gestão de pessoas.

A new MILP based approach for unit commitment in power production planning

This paper presents a complete, quadratic programming formulation of the standard thermal unit commitment problem in power generation planning, together with a novel iterative optimisation algorithm for its solution. The algorithm, based on a mixed-integer formulation of the problem, considers piecewise linear approximations of the quadratic fuel cost function that are dynamically updated in an iterative way, converging to the optimum; this avoids the requirement of resorting to quadratic programming, making the solution process much quicker. From extensive computational tests on a broad set of benchmark instances of this problem, the algorithm was found to be flexible and capable of easily incorporating different problem constraints. Indeed, it is able to tackle ramp constraints, which although very important in practice were rarely considered in previous publications. Most importantly, optimal solutions were obtained for several well-known benchmark instances, including instances of practical relevance, that are not yet known to have been solved to optimality. Computational experiments and their results showed that the method proposed is both simple and extremely effective.

Professional and community satisfaction with the Brazilian family health strategy

OBJECTIVE: To analyze the strengths and limitations of the Family Health Strategy from the perspective of health care professionals and the community. METHODS: Between June-August 2009, in the city of Vespasiano, Minas Gerais State, Southeastern Brazil, a questionnaire was used to evaluate the Family Health Strategy (ESF) with 77 healthcare professionals and 293 caregivers of children under five. Health care professional training, community access to health care, communication with patients and delivery of health education and pediatric care were the main points of interest in the evaluation. Logistic regression analysis was used to obtain odds ratios and 95% confidence intervals as well as to assess the statistical significance of the variables studied. RESULTS: The majority of health care professionals reported their program training was insufficient in quantity, content and method of delivery. Caregivers and professionals identified similar weaknesses (services not accessible to the community, lack of healthcare professionals, poor training for professionals) and strengths (community health worker-patient communications, provision of educational information, and pediatric care). Recommendations for improvement included: more doctors and specialists, more and better training, and scheduling improvements. Caregiver satisfaction with the ESF was found to be related to perceived benefits such as community health agent household visits (OR 5.8, 95%CI 2.8;12.1), good professional-patient relationships (OR 4.8, 95%CI 2.5;9.3), and family-focused health (OR 4.1, 95%CI 1.6;10.2); and perceived problems such as lack of personnel (OR 0.3, 95%CI 0.2;0.6), difficulty with access (OR 0.2, 95%CI 0.1;0.4), and poor quality of care (OR 0.3, 95%CI 0.1;0.6). Overall, 62% of caregivers reported being generally satisfied with the ESF services. CONCLUSIONS: Identifying the limitations and strengths of the Family Health Strategy from the healthcare professional and caregiver perspective may serve to advance primary community healthcare in Brazil.

Spinning reserve and emission unit commitment through stochastic optimization

This paper proposes a stochastic mixed-integer linear approach to deal with a short-term unit commitment problem with uncertainty on a deregulated electricity market that includes day-ahead bidding and bilateral contracts. The proposed approach considers the typically operation constraints on the thermal units and a spinning reserve. The uncertainty is due to the electricity prices, which are modeled by a scenario set, allowing an acceptable computation. Moreover, emission allowances are considered in a manner to allow for the consideration of environmental constraints. A case study to illustrate the usefulness of the proposed approach is presented and an assessment of the cost for the spinning reserve is obtained by a comparison between the situation with and without spinning reserve.
