As ferramentas de gestão estratégica na avaliação de desempenho organizacional das Forças Armadas

As organizações em geral procuram alcançar objetivos, adotando estratégias que lhes permitam cumprir aquele desiderato com a máxima eficiência e eficácia. Os ramos das Forças Armadas procuram implementar a estratégia ao longo de um período que, face ao impacto das alterações entretanto verificadas, exige a capacidade para fazer ajustamentos àquela estratégia inicial. Nesse sentido, recorrem a ferramentas para avaliar o desempenho organizacional, que lhes permita saber qual o desempenho real e quais os ajustamentos necessários a fazer para alcançar esses objetivos. O objeto de estudo são as ferramentas de gestão estratégica utilizadas pelos ramos das Forças Armadas com o objetivo de analisar a sua pertinência, a sua eficiência na avaliação do desempenho organizacional e as diferenças relativamente ao Sistema Integrado de Gestão e Avaliação do Desempenho na Administração Pública (SIADAP). Seguiu-se uma estratégia de investigação qualitativa e um desenho de pesquisa comparativo, verificando-se que as ferramentas de gestão estratégica são pertinentes para a formulação e implementação da estratégia, são eficientes na avaliação do desempenho organizacional e diferenciam-se do SIADAP por integrarem a formulação, a implementação e a avaliação da estratégia segundo quatro perspetivas relevantes para o cumprimento da missão dos ramos das Forças Armadas. Abstract: The general organizations seek to achieve goals, adopting strategies that will enable them to fulfil that desideratum with maximum efficiency and effectiveness. The branches of the armed forces seek to implement the strategy over a period that address the impact of changes however checked, and it requires the ability to make adjustments to that initial strategy. In that sense, they use tools to assess organizational performance, enabling them to know what the actual performance and what adjustments needed to do to achieve those goals. The object of study are the strategic management tools used in the branches of the armed forces, with the aim of analysing their relevance, their effectiveness in assessing organizational performance and the differences from the Integrated Management and Performance Evaluation System in Public Administration (SIADAP). There was a qualitative research strategy and a comparative research design, verifying that the strategic management tools are relevant to the formulation and implementation of strategy, are effective in assessing organizational performance and differentiate SIADAP by integrating the formulation, implementation and evaluation of the strategy in four relevant perspectives to fulfil the mission of the branches of the armed forces.

Metodologias de avaliação do desempenho : aplicação do balanced scorecard nas modalidades de combate do Estádio Universitário de Lisboa

No contexto actual, de exigência de serviços de qualidade por parte da sociedade, os sistemas de avaliação do desempenho são essenciais para as organizações trilharem o caminho do sucesso. Assim sendo, a metodologia Balanced Scorecard, é a ideal para dar resposta a um combinado de problemas comuns a várias organizações, sendo um deles a gestão exclusivamente assente em indicadores financeiros. A metodologia empregue neste trabalho é uma investigação descritiva, representativa de um estudo de caso. Os instrumentos de pesquisa utilizados para a recolha de dados, foram as entrevistas não estruturadas, inquéritos de satisfação a utentes e colaboradores da escola e a análise documental. A principal conclusão deste estudo é que a metodologia Balanced Scorecard pode melhorar em vários aspectos, as perspectivas de aprendizagem e desenvolvimento, processo, financeira e clientes, possibilitando uma forma mais clara e precisa do caminho que deve ser percorrido pelo gestor, de forma a atingir todos os seus objectivos, nunca se desviando da sua missão.

Organização e implementação de um balanced scorecard num serviço periférico da administração directa do estado - condicionantes e potencialidades para uma gestão mais eficiente : o caso da DSCST da DRE-Alentejo

Os serviços públicos estão confrontados, cada vez mais, com uma envolvente externa e interna mais exigente, o que inevitavelmente obriga à introdução da abordagem estratégica. A avaliação de desempenho na Administração Pública, obriga à integração de metodologias de gestão estratégica, que podem ser monitorizadas com o Balanced Scorecard (BSC), funcionando este como núcleo para alimentar os ciclos anuais de gestão e o sistema de avaliação de desempenho, contribuindo assim para melhorar a gestão dessas organizações. Este trabalho consubstancia uma proposta de projecto de organização e implementação de um BSC num serviço público específico, nomeadamente a Direcção de Serviços do Comércio e Serviços e do Turismo (DSCST) da Direcção Regional da Economia do Alentejo (DRE­ Alentejo). A abordagem estratégica na DRE-Alentejo e na DSCST, apoiada no BSC, constitui uma iniciativa que implica mudanças. Permite simplificar a definição da estratégia e do plano estratégico, apoiar a construção dos planos de actividades, o mapa de pessoal, a carta de missão, facilitar a comunicação da estratégia no interior e exterior da organização. Permite ainda o alinhamento e a articulação dos objectivos em todos os níveis hierárquicos com a estratégia, bem como a medição da eficácia da estratégia. Abstract: Government departments increasingly operate within an ever more demanding environment, in both internal and external terms, and there is therefore a requirement for the adoption of a strategic approach to public administration. Performance evaluation requires the use of strategic management methodologies monitored by means of a Balanced Scorecard (BSC), which provides data for annual management reviews and the performance evaluation system, thereby contributing towards the improved management of government departments. ln this paper a proposal is presented for the organization and implementation of a BSC in a specific public department, the (DRE-Alentejo) Alentejo Regional Department of Economic Affairs (DSCST) Department of Commerce and Tourism. The strategic approach based on BSC adopted by the DRE-Alentejo involves changes in the management system. The process of setting strategy and drawing up a strategic plan is simplified, and the approach helps in the drawing up of activity plans, the official staff plan and the mission statement; it also enables the organization's strategy to be better understood both internally and externally, while bringing it into line with objectives, which can be more coherently pursued at all levels; finally, it allows for the effectiveness of strategy to be gauged.

Interest rate (in)sensitivity of emerging market corporate debt : economic analysis based on 2002-2015 empirical evidence

Interest rate sensitivity assessment framework based on fixed income yield indexes is developed and applied to two types of emerging market corporate debt: investment grade and high yield exposures. Our research advances beyond the correlation analyses focused on co- movements in yields and/or spreads of risky and risk-free assets. We show that correlation- based analyses of interest rate sensitivity could appear rather inconclusive and, hence, we investigate the bottom line profit and loss of a hypothetical model portfolio of corporates. We consider historical data covering the period 2002 – 2015, which enable us to assess interest rate sensitivity of assets during the development, the apogee, and the aftermath of the global financial crisis. Based on empirical evidence, both for investment and speculative grades securities, we find that the emerging market corporates exhibit two different regimes of sensitivity to interest rate changes. We observe switching from a positive sensitivity under the normal market conditions to a negative one during distressed phases of business cycles. This research sheds light on how financial institutions may approach interest rate risk management, evidencing that even plain vanilla portfolios of emerging market corporates, which on average could appear rather insensitive to the interest rate risk in fact present a binary behavior of their interest rate sensitivities. Our findings allow banks and financial institutions for optimizing economic capital under Basel III regulatory capital rules.

Governed by the cycle : direct and inverted interest-rate sensitivity of emerging market corporate debt

An innovative approach to quantify interest rate sensitivities of emerging market corporates is proposed. Our focus is centered at price sensitivity of modeled investment grade and high yield portfolios to changes in the present value of modeled portfolios composed of safe-haven assets, which define risk-free interest rates. Our methodology is based on blended yield indexes. Modeled investment horizons are always kept above one year thus allowing to derive empirical implications for practical strategies of interest rate risk management in the banking book. As our study spans over the period 2002 – 2015, it covers interest rate sensitivity of assets under the pre-crisis, crisis, and post-crisis phases of the economic cycles. We demonstrate that the emerging market corporate bonds both, investment grade and high yield types, depending on the phase of a business cycle exhibit diverse regimes of sensitivity to interest rate changes. We observe switching from a direct positive sensitivity under the normal pre-crisis market conditions to an inverted negative sensitivity during distressed turmoil of the recent financial crisis, and than back to direct positive but weaker sensitivity under new normal post-crisis conjuncture. Our unusual blended yield-based approach allows us to present theoretical explanations of such phenomena from economics point of view and helps us to solve an old controversy regarding positive or negative responses of credit spreads to interest rates. We present numerical quantification of sensitivities, which corroborate with our conclusion that hedging of interest rate risk ought to be a dynamic process linked to the phases of business cycles as we evidence a binary-like behavior of interest rate sensitivities along the economic time. Our findings allow banks and financial institutions for approaching downside risk management and optimizing economic capital under Basel III regulatory capital rules.

A survey on multi-output regression

In recent years, a plethora of approaches have been proposed to deal with the increasingly challenging task of multi-output regression. This paper provides a survey on state-of-the-art multi-output regression methods, that are categorized as problem transformation and algorithm adaptation methods. In addition, we present the mostly used performance evaluation measures, publicly available data sets for multi-output regression real-world problems, as well as open-source software frameworks.

Reliability-aware distributed computing scheduling policy

One of the primary issues associated with the efficient and effective utilization of distributed computing is resource management and scheduling. As distributed computing resource failure is a common occurrence, the issue of deploying support for integrated scheduling and fault-tolerant approaches becomes paramount importance. To this end, we propose a fault-tolerant dynamic scheduling policy that loosely couples dynamic job scheduling with job replication scheme such that jobs are efficiently and reliably executed. The novelty of the proposed algorithm is that it uses passive replication approach under high system load and active replication approach under low system loads. The switch between these two replication methods is also done dynamically and transparently. Performance evaluation of the proposed fault-tolerant scheduler and a comparison with similar fault-tolerant scheduling policy is presented and shown that the proposed policy performs better than the existing approach.

Preparation of an Immunosorbent and its use in the Solid Phase Extraction of Benzodiazepines

The use of capillary electrophoresis (CE) has been restricted to applications having high sample concentrations because of its low sensitivity caused by small injection volumes and, when ultraviolet (UV) detection is used, the short optical path length. Sensitivity in CE can be improved by using more sensitive detection systems, or by preconcentration techniques which are based on chromatographic and/or electrophoretic principles. One of the promising strategies to improve sensitivity is solid phase extraction (SPE). Solid Phase Extraction utilizes high sample volumes and a variety of complex matrixes to facilitate trace detection. To increase the specificity of the SPE a selective solid phase must be chosen. Immunosorbents, which are a combination of an antibody and a solid support, have proven to be an excellent option because of high selectivity of the antibody. This thesis is an exploratory study of the application of immunosorbent-SPE combined with CE for trace concentration of benzodiazepines. This research describes the immobilization and performance evaluation of an immunosorbent prepared by immobilizing a benzodiazepine-specific antibody on aminopropyl silica. The binding capacity of the immunosorbent, measured as µg of benzodiazepine/ gram of immunosorbent, was 39 ± 10. The long term stability of the prepared immunosorbent has been improved by capping the remaining aminopropyl groups by reaction with acetic anhydride. The capped immunosorbent retained its binding capacity after several uses.

Theory and optimisation of 1.3 and 1.55 μm (Al)InGaAs metamorphic quantum well lasers

The use of InGaAs metamorphic buffer layers (MBLs) to facilitate the growth of lattice-mismatched heterostructures constitutes an attractive approach to developing long-wavelength semiconductor lasers on GaAs substrates, since they offer the improved carrier and optical confinement associated with GaAs-based materials. We present a theoretical study of GaAs-based 1.3 and 1.55 μm (Al)InGaAs quantum well (QW) lasers grown on InGaAs MBLs. We demonstrate that optimised 1.3 μm metamorphic devices offer low threshold current densities and high differential gain, which compare favourably with InP-based devices. Overall, our analysis highlights and quantifies the potential of metamorphic QWs for the development of GaAs-based long-wavelength semiconductor lasers, and also provides guidelines for the design of optimised devices.
