Corporate brand identity management in a technological faculty – how brand relationships influence students and companies reputations

Identity is traditionally defined as an emission concept [1]. Yet, some research points out that there are external factors that can influence it [2]; [3]; [4]. This subject is even more relevant if one considers corporate brands. According to Aaker [5] the number, the power and the credibility of corporate associations are bigger in the case of corporate brands. Literature recognizes the influence of relationships between companies in identity management. Yet, given the increasingly important role of corporate brands, it is surprising that to date no attempt to evaluate that influence has been made in the management of corporate brand identity. Also Keller and Lehman [6] highlight relationships and costumer experience as two areas requiring more investigation. In line with this, the authors intend to develop an empirical research in order to evaluate the influence of relationships between brands in the identity of corporate brand from an internal perspective by interviewing internal stakeholders (brand managers and internal clients). This paper is organized by main contents: theoretical background, research methodology, data analysis and conclusions and finally cues to future investigation.

Reactive power management strategies in future smart grids

The reactive power management in distribution network with large penetration of distributed energy resources is an important task in future power systems. The control of reactive power allows the inclusion of more distributed recourses and a more efficient operation of distributed network. Currently, the reactive power is only controlled in large power plants and in high and very high voltage substations. In this paper, several reactive power control strategies considering a smart grids paradigm are proposed. In this context, the management of distributed energy resources and of the distribution network by an aggregator, namely Virtual Power Player (VPP), is proposed and implemented in a MAS simulation tool. The proposed methods have been computationally implemented and tested using a 32-bus distribution network with intensive use of distributed resources, mainly the distributed generation based on renewable resources. Results concerning the evaluation of the reactive power management algorithms are also presented and compared.

Distributed generation producers' reserve management

Sustainable development concerns are being addressed with increasing attention, in general, and in the scope of power industry, in particular. The use of distributed generation (DG), mainly based on renewable sources, has been seen as an interesting approach to this problem. However, the increasing of DG in power systems raises some complex technical and economic issues. This paper presents ViProd, a simulation tool that allows modeling and simulating DG operation and participation in electricity markets. This paper mainly focuses on the operation of Virtual Power Producers (VPP) which are producers’ aggregations, being these producers mainly of DG type. The paper presents several reserve management strategies implemented in the scope of ViProd and the results of a case study, based on real data.

Reliability and availability in reconfigurable computing: a basis for a common solution

Dynamically reconfigurable SRAM-based field-programmable gate arrays (FPGAs) enable the implementation of reconfigurable computing systems where several applications may be run simultaneously, sharing the available resources according to their own immediate functional requirements. To exclude malfunctioning due to faulty elements, the reliability of all FPGA resources must be guaranteed. Since resource allocation takes place asynchronously, an online structural test scheme is the only way of ensuring reliable system operation. On the other hand, this test scheme should not disturb the operation of the circuit, otherwise availability would be compromised. System performance is also influenced by the efficiency of the management strategies that must be able to dynamically allocate enough resources when requested by each application. As those resources are allocated and later released, many small free resource blocks are created, which are left unused due to performance and routing restrictions. To avoid wasting logic resources, the FPGA logic space must be defragmented regularly. This paper presents a non-intrusive active replication procedure that supports the proposed test methodology and the implementation of defragmentation strategies, assuring both the availability of resources and their perfect working condition, without disturbing system operation.

Da desmotivação à motivação: a jornada do docente

Este trabalho tem como objetivo conhecer os fatores de motivação dos professores de um agrupamento do distrito do Porto proporcionando, através desse conhecimento, uma melhor visão para a elaboração de estratégias de gestão adequadas às expectativas e às necessidades desses professores. Assim, inicia-se pela análise da profissão docente na atualidade e como as mudanças ocorridas na sociedade que contribuíram para a desmotivação dos professores e a suas implicações no bem-estar docente. De seguida, sintetizaram-se as principais contribuições das teorias da motivação na gestão das organizações, assim como a perspetiva das teorias cognitivistas da motivação. Contudo, ressalvam-se também os fatores que conduzem os professores a prevenir o mal-estar e a desenvolverem o bem-estar docente. A investigação empírica realizada no agrupamento em estudo recolheu as perceções de um grupo de professores relativamente aos fatores de motivação e desmotivação docente, assim como, estratégias diferenciadas de motivação desses professores. Os resultados deste estudo foram as linhas orientadoras para a elaboração de um plano operacional para o agrupamento em causa, com um conjunto de atividades definidas para reforçar a motivação dos seus professores. Com este trabalho espera-se ter dado um contributo para uma perspetiva de atuação profilática, capaz de ajudar os professores do agrupamento a prevenir e a atuar face ao mal-estar, promovendo o bem-estar docente e reforçando a sua motivação, atendendo à sua influência na qualidade e sucesso do ensino.
