VITAE was a four-year research project designed to explore the work and lives of a purposive sample of 300 Key Stage 1, 2 and 3 (English and maths) teachers at different phases of their careers in 100 primary and secondary schools in different socioeconomic contexts, drawn from seven local authorities in England. Its focus was upon identifying variations in different aspects of teachers' lives and work and examining possible connections between these and their effects on pupils as perceived by the teachers themselves and as measured by value-added national test scores. An integrated mixed-method approach was developed in addressing the research questions. The results showed that there were associations between teachers' work, lives and identities, that teachers' perceived and relative (valueadded) effectiveness varied within each of six professional life phases, and that this variation depended upon their capacity to manage a number of moderating and mediating factors. Statistically significant relationships were found between teacher commitment, resilience and the value-added pupil test scores. The findings from the study shed new light upon the meanings and measurement of teacher effectiveness and the complex nature and trajectories of teachers' work, lives and effectiveness in different school contexts.

Global navigation satellite system (GNSS) receivers require solutions that are compact, cheap and low-power, in order to enable their widespread proliferation into consumer products. Furthermore, interoperability of GNSS with non-navigation systems, especially communication systems will gain importance in providing the value added services in a variety of sectors, providing seamless quality of service for users. An important step into the market for Galileo is the timely availability of these hybrid multi-mode terminals for consumer applications. However, receiver architectures that are amenable to high-levels of integration will inevitably suffer from RF impairments hindering their easy widespread use in commercial products. This paper studies and presents analytical evaluations of the performance degradation due to the RF impairments and develops algorithms that can compensate for them in the DSP domain at the base band with complexity-reduced hardware overheads, hence, paving the way for low-power, highly integrated multi-mode GNSS receivers.

Num contexto de crescente complexidade e disponibilidade de informação, a gestão do capital intelectual assume cada vez mais preponderância como vantagem competitiva para as empresas que procuram maximizar o valor gerado. Esta investigação usa como metodologia príncipal o VAIC (coeficiente intelectual do valor adicionado), para assim estudar a existência de relação entre capital intelectual e a performance bolsista e financeira das empresas do PSI20. O VAIC é decomposto nos seus três indicadores de eficiência, tais como: capital humano, capital estrutural e capital físico. Os dados contemplam quinze empresas e nove anos de análise (2003 - 2011). Elaborou-se uma abordagem que recorre à utilização de técnicas econométricas para reduzir potênciais falhas no tratamento de dados em painel. Os resultados da análise demonstram uma relação positiva entre a aposta em capital intelectual a performance bolsista e financeira, ou seja, a utilização e gestão eficientes do capital intelectual contribuem de forma significativa na avaliação bolsista e financeira das empresas do PSI20.

Open innovation is a hot topic in innovation management. Its basic premise is open up the innovation process. The innovation process, in general sense, may be seen as the process of designing, developing and commercializing a novel product or service to improve the value added of a company. The development of Web 2.0 tools facilitates this kind of contributions, opening space to the emergence of crowdsourcing innovation initiatives. Crowdsourcing is a form of outsourcing not directed to other companies but to the crowd by means of an open call mostly through an Internet platform. Innovation intermediaries, in general sense, are organizations that work to enable innovation, that just act as brokers or agents between two or more parties. Usually, they are also engaged in other activities like inter-organizational networking and technology development and related activities. A crowdsourcing innovation intermediary is an organization that mediates the communication and relationship between the seekers – companies that aspire to solve some problem or to take advantage of any business opportunity – with a crowd that is prone to give ideas based on their knowledge, experience and wisdom. This paper identifies and analyses the functions to be performed by an intermediary of crowdsourcing innovation through grounded theory analyses from literature. The resulting model is presented and explained. The resulting model summarizes eight main functions that can be performed by a crowdsourcing process, namely, diagnoses, mediation, linking knowledge, community, evaluation, project management, intellectual property governance and marketing and support. These functions are associated with a learning cycle process which covers all the crowdsourcing activities that can be realized by the broker.

Ao longo dos tempos que a economia tem sofrido mudanças a nível global, e é possível verificar que as empresas estão constantemente a adaptar-se a essa mudança. Fruto dessa adaptação, os recursos humanos, que são uma das partes fundamentais de uma empresa pois representam a sua mão-de-obra, têm tido um papel junto da mesma significativamente alterado ao longo do tempo. De facto, não só o papel dos recursos humanos tem sido diferente ao longo do tempo, a própria gestão de recursos humanos evoluiu significativamente, a par da própria evolução das várias estruturas organizacionais. Tudo isto se relaciona com a necessidade de encontrar métodos de diferenciação, de adquirir vantagem competitiva, ou de conseguir obter mais valor num mercado cada vez mais competitivo a todos os níveis. Assim, embora hoje em dia se assuma de um modo geral que os recursos humanos são realmente uma fonte de valor, capazes de fazer com que a sua empresa se diferencie, e capazes de criar vantagem competitiva, a verdade é que para que tal seja possível é necessário uma gestão dos mesmos que o possibilite. A gestão de recursos humanos traduz-se sobretudo nas suas práticas, tais como o recrutamento ou a formação, e para que essas práticas tenham o melhor efeito possível é necessário que as mesmas sejam avaliadas de forma imparcial, ou seja, independente. É neste contexto que surge a Auditoria de Recursos Humanos, que se pode resumir a uma avaliação aos recursos humanos e à sua gestão dos pontos de vista legal, funcional, e estratégico. Com o objectivo de verificar se, no contexto português, as empresas pensam nos seus recursos humanos como um recurso que acrescenta valor se gerido adequadamente, e se apostam neste tipo de auditoria como forma de avaliar o paradigma dos seus recursos humanos, foi elaborado um questionário e enviado a empresas distinguidas com os estatutos PME Líder 2014 e PME Excelência 2014 pelo IAPMEI. As conclusões do estudo indicaram que embora as empresas acreditem que os recursos humanos acrescentam valor, apostando na sua motivação, formação, avaliação de desempenho e satisfação, as mesmas não fazem questão em obter a certificação dos seus sistemas de gestão de recursos humanos e não utilizam a auditoria de recursos humanos como uma ferramenta de gestão.

O presente trabalho tem como objetivo o cultivo da microalga Chlorella zofingiensis, e a avaliação da sua potencial aplicação na produção de biodiesel e de produtos de valor acrescentado, de entre os quais se destacam os antioxidantes. Com o intuito da produção de biocombustível é necessário efetuar o cultivo da microalga num volume que permita a obtenção de elevada quantidade de biomassa para a concretização do trabalho. Além deste biocombustível, existe ainda a possibilidade de valorização de alguns produtos com valor comercial, como é o caso da astaxantina, a saber na área farmacêutica, alimentar ou até mesmo cosmética. O cultivo da microalga foi feito em meio Bold’s Basal Medium (BBM), inicialmente em matrazes de 5 L e, quando se obteve uma cultura suficientemente densa, inocularam-se fotobiorreatores de 50 L. Conseguiu-se atingir uma concentração máxima de 0,76 g/L, no reator de 5 L, após cerca de 6 semanas de ensaio. Por sua vez, em fotobiorreatores de 50 L, a concentração máxima obtida foi de 0,4 g/L, após 4 semanas de ensaio. Nestas culturas foi possível obter-se uma percentagem lipídica de 7 %, apresentado concentração de pigmentos por litro de cultura na ordem dos 10 mg/L, 4 mg/L e 2 mg/L de clorofila a, clorofila b e carotenoides totais, respetivamente. Com esta percentagem lipídica recuperaram-se 400 mg de óleo, obtendo-se posteriormente 280 mg de biodiesel. Pela análise à amostra de biodiesel obtida foi possível obter o perfil lipídico desta microalga, quando cultivada em meio BBM, sendo 41% de ácido palmítico (C16:0), 9% de ácido esteárico (C18:0), 27% de ácido oleico (C18:1) e 23% de ácido linoleico (C18:2). Os resultados obtidos mostram que a Chlorella zofingiensis é uma microalga com interesse potencial para a produção de clorofila e carotenóides, mas não para o óleo para a produção de biodiesel.

This paper studies strategies to attract students from outside Europe to European preexperience masters. We characterize the value added by such masters through interviews with key players at the universities and multinational recruiting corporations. We considered a strategy for segmenting international students in the US and extended it to the European market. We have analyzed data from international applications to Nova SBE as a proxy for applications in European institutions. Based on that analysis we conclude with recommendations to attract suitable candidates from outside Europe. In particular we also provided three different solutions to attract students from the southern hemisphere: we conclude that European institutions should (a) increase the spring semester intake, (b) provide bridging courses for some students, or (c) could place some accepted candidates in internships before starting classes.

The global dynamics of alliances are strongly determined by the level of cooperation among states. This cooperation can be embodied in various aspects, but the level of defense and security cooperation becomes usually more doctrinal and lasting. By the nature of sovereignty that instills in the bilateral relationship, cooperation at defense and security level can leverages other forms of cooperation. The circumstances and relational balance between Brazil and Portugal seem to evolve towards distancing opportunities, despite they are culturally and institutionally untainted. The economic dynamics, the strategic projection in global sustainability terms, the scale and ambition of Brazilian regional leadership, contrasts with the actual context of Portugal, distancing himself both on the stage where they operate. On the other hand, the historical and cultural roots, the language, the affinity of the peoples of CPLP and some opportunities for economic niches, trend to attract both countries. The condition of Portugal in NATO and Europe, coupled with the ability to export technical and human resources to value-added for Brazil, seems also to become approaching factors. On the balance of these dynamics, there is a set of exogenous factors (economic, external global relations matrix, regional stability, among others), which are not always controlled by any of both countries. These factors call for strong capacity for foresight analysis and decision making, with the inherent risk. There is cooperation vectors that are not apparently penalized by geographic distance, or by the difference of realities. Among these vectors we shall highlight synergies in technological niches, highly tradable goods and, mostly, using the domain of dual technologies. The thirteen niches herein identified are: Monitoring, Navigation, Command and Control, Electronics, Optoelectronics, Communication and remote sensing, Information Technologies, Flight Simulation, Specialized Training, Fiber Optic Sensors, Materials Engineering, Nanotechnology and Communications. Cumulating with identified opportunities in traditional relational framework, both countries are growing (in geography and economic terms) into the Atlantic, making it a central element in the bilateral approach. By being at the same time a growing stage of disputes and which stability tends to be threatened, it will be done an analysis of these synergistic vectors, superimposed on the impact on Atlantic securitization process.

La mondialisation a favorisé l’essor de l’innovation collaborative entraînant une augmentation du nombre de partenariats entre différents acteurs. Grâce à leurs avantages multiples, les projets conjoints jouent un rôle fondamental dans le développement économique et industriel des secteurs à forte valeur ajoutée. Dans cette optique, la création ou la quantification de valeur par l’innovation collaborative repose en grande partie sur la capacité à commercialiser des innovations encadrées par une protection intellectuelle adéquate. Ainsi, la tendance mondiale témoigne d’une augmentation accrue des dépôts conjoints de brevets entre diverses entités. Ces co-dépôts soulèvent une variété de questions juridiques puisque les régimes statutaires ne sont pas nécessairement adaptés à la réalité des partenariats. D’abord, les régimes lacunaires proposés par les lois n’anticipent pas les conséquences juridiques de l’interaction entre divers acteurs. La variété de configurations d’intervenants et la typologie des partenariats entraînent une confusion entre les inventeurs et les propriétaires lors du dépôt d’une demande de brevet. Cette situation peut également induire de facto la copropriété d’un brevet pouvant causer des litiges et miner l’énorme valeur des brevets conjoints. Ensuite, les régimes statutaires sont également déficients à l’étape de l’exploitation d’un brevet conjoint. En comparant les régimes juridiques canadiens et américains, il devient possible de mieux cerner les enjeux juridiques associés aux questionnements présents lors de l’élaboration d’un partenariat. Afin d’obtenir des retombées fructueuses des brevets conjoints, une mise en forme contractuelle est proposée pour pallier ces lacunes statutaires. Grâce à des outils contractuels et à une planification pré-contractuelle, les copropriétaires pourront réaliser l’énorme potentiel de cette institution.

This thesis Entitled distribution ,diversity and biology of deep-sea fishes the indian Eez.Fishing rights and responsibilities it entails in the deep-sea sector has been a vexed issue since the mid-nineties and various stakeholders have different opinion on the modalities of harnessing the marine fisheries wealth, especially from the oceanic and deeper waters. The exploitation and utilization of these esources requires technology development and upgradation in harvest and post-harvest areas; besides shore infrastructure for berthing, handling, storing and processing facilities. At present, although deep-sea fishes don’t have any ready market in our country it can be converted into value added products. Many problems have so far confronted the deep-sea fishing sector not allowing it to reach its full potential. Hence, there should be a sound deep-sea fishing policy revolving round the upgradation of the capabilities of small scale fishermen, who have the inherent skills but do not have adequate support to develop themselves and to acquire vessels having the capability to operate in farther and deeper waters. Prospects for the commercial exploitation and utilization of deep-sea fishes were analyzed using SWOL analysis.
