Perspectives of the Internal Public in a Cultural Event: the Case of Noc Noc, Guimarães - Portugal

Given the significant impact that cultural events may have in local communities and the inherent organization complexity, it is important to understand their specificities. Most of the times cultural events disregard marketing and often marketing is distant from art. Thus an analysis of an inside perspective might bring significant returns to the organization of such an event. This paper considers the three editions (2011, 2012 and 2013) of a cultural event – Noc Noc – organized by a local association in the city of Guimarães, Portugal. Its format is based in analogous events, as Noc Noc intends to convert everyday spaces (homes, commercial outlets and a number of other buildings) into cultural spaces, processed and transformed by artists, hosts and audiences. By interviewing a sample of people (20) who have hosted this cultural event, sometimes doubling as artists, and by experiencing the three editions of the event, this paper illustrates how the internal public understands this particular cultural event, analyzing specifically their motivations, ways of acting and participating, as well as their relationship with the public, with the organization of the event and with art in general. Results support that artists and hosts motivations must be identified in a timely and appropriate moment, as well as their views of this particular cultural event, in order to keep them participating, since low budget cultural events such as this one may have a key role in small scale cities.

Fazer uma história da própria vida. Narrativa pessoal e memória comunicativa em Paul Schatz im uhrenkasten

This essay offers a reflection on the concepts of identity and personal narrative, a line of argument that is closely interlaced with a subject‘s capacity to self-representation. As self-representation is necessarily composed upon remembrance processes, the question of memory as an element that directly influences the formation of an individual‘s identity becomes an emergent topic. Bearing this objective in mind, I shall highlight the notion of biographic continuity, the ability to elaborate a personal narrative, as an essential prerogative to attain a sense of identitary cohesion and coherence. On the other hand, I will argue that not only experienced memories play a key role in this process; intermediated, received narratives from the past, memories transmitted either symbolically or by elder members of the group or, what has been meanwhile termed ―postmemory‖, also influence the development of an individual‘s identitary map. This theoretical framework will be illustrated with the novel Paul Schatz im Uhrenkasten, written by German post-Holocaust author Jan Koneffke.

Identity and belonging in the novels of Dorn Rabinovici

This essay analyses how the different types of memory may influence the process of identity formation. It shall be argued that not only memories formed upon the subject’s experiences play a key role in this process; intermediated, received narratives from the past, memories transmitted either symbolically or by elder members of the group, or, what has been meanwhile termed as “postmemory”, also play an important part in the development of an individual’s identitary map. This theoretical framework will be illustrated with the novelistic work of Austrian Israeli-born historian, writer and political activist Doron Rabinovici (*1961). As a representative of the so-called “second generation” of Holocaust writers, a generation of individuals who did not experience the nazi genocide violence, but who had to form their identities under the shadow of such a brutal past, Rabinovici addresses essential topics such as the intergenerational transmission of memory and guilt within survivor families, identity formation of second generation individuals (Jews and non-Jews) and the question of simultaneously belonging to different social, historical and linguistic contexts.

Influence of Soil Chemistry and Plant Physiology in the Phytoremediation of Cu, Mn, and Zn

Different anthropogenic sources of metals can result from agricultural, industrial, military, mining and urban activities that contribute to environmental pollution. Plants can be grown for phytoremediation to remove or stabilize contaminants in water and soil. Copper (Cu), manganese (Mn) and zinc (Zn) are trace essential metals for plants, although their role in homeostasis in plants must be strictly regulated to avoid toxicity. In this review, we summarize the processes involved in the bioavailability, uptake, transport and storage of Cu, Mn and Zn in plants. The efficiency of phytoremediation depends on several factors including metal bioavailability and plant uptake, translocation and tolerance mechanisms. Soil parameters, such as clay fraction, organic matter content, oxidation state, pH, redox potential, aeration, and the presence of specific organisms, play fundamental roles in the uptake of trace essential metals. Key processes in the metal homeostasis network in plants have been identified. Membrane transporters involved in the acquisition, transport and storage of trace essential metals are reviewed. Recent advances in understanding the biochemical and molecular mechanisms of Cu, Mn and Zn hyperaccumulation are described. The use of plant-bacteria associations, plant-fungi associations and genetic engineering has opened a new range of opportunities to improve the efficiency of phytoremediation. The main directions for future research are proposed from the investigation of published results.

Dynamical Stability and Predictability of Football Players: The Study of One Match

The game of football demands new computational approaches to measure individual and collective performance. Understanding the phenomena involved in the game may foster the identification of strengths and weaknesses, not only of each player, but also of the whole team. The development of assertive quantitative methodologies constitutes a key element in sports training. In football, the predictability and stability inherent in the motion of a given player may be seen as one of the most important concepts to fully characterise the variability of the whole team. This paper characterises the predictability and stability levels of players during an official football match. A Fractional Calculus (FC) approach to define a player’s trajectory. By applying FC, one can benefit from newly considered modeling perspectives, such as the fractional coefficient, to estimate a player’s predictability and stability. This paper also formulates the concept of attraction domain, related to the tactical region of each player, inspired by stability theory principles. To compare the variability inherent in the player’s process variables (e.g., distance covered) and to assess his predictability and stability, entropy measures are considered. Experimental results suggest that the most predictable player is the goalkeeper while, conversely, the most unpredictable players are the midfielders. We also conclude that, despite his predictability, the goalkeeper is the most unstable player, while lateral defenders are the most stable during the match.

The existence of skilled professionals able to organize, evaluate, select and disseminate information in organizations appears to be a prerequisite for success. The skills necessary for the formation of a professional devoted to the management of information and knowledge in the context of business organizations will be analysed. Then data collected in two focus group discussion with students from a graduate course in Business Information, from Polytechnic Institute of Porto, Portugal, a will be examined.

Dispatch of distributed Energy Resources to Provide Energy and Reserve in Smart Grids using a Particle Swarm Optimization Approach

The smart grid concept is a key issue in the future power systems, namely at the distribution level, with deep concerns in the operation and planning of these systems. Several advantages and benefits for both technical and economic operation of the power system and of the electricity markets are recognized. The increasing integration of demand response and distributed generation resources, all of them mostly with small scale distributed characteristics, leads to the need of aggregating entities such as Virtual Power Players. The operation business models become more complex in the context of smart grid operation. Computational intelligence methods can be used to give a suitable solution for the resources scheduling problem considering the time constraints. This paper proposes a methodology for a joint dispatch of demand response and distributed generation to provide energy and reserve by a virtual power player that operates a distribution network. The optimal schedule minimizes the operation costs and it is obtained using a particle swarm optimization approach, which is compared with a deterministic approach used as reference methodology. The proposed method is applied to a 33-bus distribution network with 32 medium voltage consumers and 66 distributed generation units.

Culture-dependent characterization of cyanobacterial diversity in the intertidal zones of the Portuguese coast: A polyphasic study

Cyanobacteria are important primary producers, and many are able to fix atmospheric nitrogen playing a key role in the marine environment. However, not much is known about the diversity of cyanobacteria in Portuguese marine waters. This paper describes the diversity of 60 strains isolated from benthic habitats in 9 sites (intertidal zones) on the Portuguese South and West coasts. The strains were characterized by a morphological study (light and electron microscopy) and by a molecular characterization (partial 16S rRNA, nifH, nifK, mcyA, mcyE/ndaF, sxtI genes). The morphological analyses revealed 35 morphotypes (15 genera and 16 species) belonging to 4 cyanobacterial Orders/Subsections. The dominant groups among the isolates were the Oscillatoriales. There is a broad congruence between morphological and molecular assignments. The 16S rRNA gene sequences of 9 strains have less than 97% similarity compared to the sequences in the databases, revealing novel cyanobacterial diversity. Phylogenetic analysis, based on partial 16S rRNA gene sequences showed at least 12 clusters. One-third of the isolates are potential N2-fixers, as they exhibit heterocysts or the presence of nif genes was demonstrated by PCR. Additionally, no conventional freshwater toxins genes were detected by PCR screening.

Metodologia BIM, aplicada à preparação, controlo e gestão de obra

O âmbito deste trabalho envolve o teste do modelo BIM numa obra em construção pela Mota-Engil – Engenharia, na extração experimental de peças desenhadas de preparação e apoio à execução de obra. No capítulo 1 deste relatório são definidos o âmbito e os objetivos deste trabalho, é feito um enquadramento histórico do tema e abordados conceitos e atividades da preparação de obra, na sua forma tradicional. O estado do conhecimento da preparação de obras e mais em concreto da tecnologia BIM a nível nacional e internacional é abordado no capítulo 2. Nesse sentido procura-se definir os conceitos principais inerentes a esta nova metodologia, que passa por identificar e caraterizar a tecnologia envolvida e o seu nível de desenvolvimento. Com suporte em casos práticos de preparação de obra na sua forma tradicional, identificados e desenvolvidos no capítulo 3, foi compilado um processo tipo de peças desenhadas de suporte identificadas e caracterizadas no capítulo 4, frequentes e comuns à execução de diversos tipos de obras de edifícios. Assente na compilação baseada em casos práticos e no estudo do projeto de execução da empreitada que sustenta o presente trabalho, com base no qual o modelo BIM foi concebido, identificou-se um conjunto de peças desenhadas de preparação e apoio à execução dos trabalhos, em 2D, a extrair do modelo. No capítulo 5, é feita uma descrição do modo como foi estudado o projeto da obra, com evidência para os fatores mais relevantes, especificando os desenhos a extrair. Suportada pelo programa de modelação ArchiCAD, a extração do conjunto de desenhos identificados anteriormente foi conseguida com recurso às funcionalidades disponíveis no software, que permite a criação de desenhos 2D atualizáveis ou não automaticamente a partir do modelo. Qualquer alteração introduzida no modelo virtual é automaticamente atualizada nos desenhos bidimensionais, caso o utilizador assim o pretenda. Ao longo desse trabalho foram detetados e analisados os condicionalismos inerentes ao processo de extração, referidos no capítulo 6, para estabelecimento de regras de modelação padrão a adotar em futuras empreitadas, que possam simplificar a obtenção dos elementos desenhados de preparação necessários à sua execução. No ponto 6.3 são identificadas melhorias a introduzir no modelo. Em conclusão no capítulo 7 são abordadas especificidades do setor da construção que sustentam e evidenciam cada vez mais a necessidade de utilizar as novas tecnologias com vista à adoção de práticas e ferramentas padrão de apoio à execução de obras. Sendo a tecnologia BIM, transversal a todo o setor, a sua utilização com regras padrão na conceção dos modelos e na extração de dados, potencia a otimização dos custos, do tempo, dos recursos e da qualidade final de um empreendimento, ao longo de todo o seu ciclo de vida, para além de apoiar com elevada fiabilidade as tomadas de decisão ao longo desse período. A tecnologia BIM, possibilita a antevisão do edifício a construir com um elevado grau de pormenor, com todas as vantagens que daí advêm.

Cation transporters/channels in plants: Tools for nutrient biofortification

Cation transporters/channels are key players in a wide range of physiological functions in plants, including cell signaling, osmoregulation, plant nutrition and metal tolerance. The recent identification of genes encoding some of these transport systems has allowed new studies toward further understanding of their integrated roles in plant. This review summarizes recent discoveries regarding the function and regulation of the multiple systems involved in cation transport in plant cells. The role of membrane transport in the uptake, distribution and accumulation of cations in plant tissues, cell types and subcellular compartments is described. We also discuss how the knowledge of inter- and intra-species variation in cation uptake, transport and accumulation as well as the molecular mechanisms responsible for these processes can be used to increase nutrient phytoavailability and nutrients accumulation in the edible tissues of plants. The main trends for future research in the field of biofortification are proposed.
