Aprender inglês como segunda língua : a importância do domínio de outras línguas num mundo globalizado

“Aprender inglês como segunda língua – A importância do Domínio de outras línguas num mundo globalizado” é um trabalho de investigação que visa abordar a importância da aprendizagem da língua inglesa na perspetiva dos alunos no final do 3º Ciclo do Ensino Básico e tendo em conta o mundo globalizado em que vivemos. A metodologia a aplicar é do tipo descritivo. Os sujeitos são 101 alunos do 9º ano de escolaridade do Ensino Básico, pertencentes ao Colégio Vasco da Gama, perfazendo cinco turmas. Para ter acesso às opiniões dos alunos, recorremos à elaboração de questionários estruturados de acordo com os objetivos da investigação. Os questionários foram aplicados em aula com a devida autorização da Direção do Colégio. Procuramos apurar se, de acordo com a legislação europeia que valoriza a aprendizagem de várias línguas como forma de aproximar os vários países da comunidade, nomeadamente de uma língua franca que possa ser o meio de comunicação preferencial no mundo político, económico, social e cultural, os alunos valorizam a aquisição da língua estrangeira e em caso afirmativo, quais as funções e com que objetivos pretendem os alunos atingir a fluência na língua inglesa. No que diz respeito aos resultados obtidos, podemos afirmar que os alunos valorizam o domínio de outras línguas num mundo globalizado, em especial o domínio da língua inglesa visto ser considerada a língua franca internacional que permite a comunicação entre povos de diferentes línguas maternas. Também o enriquecimento cultural e o desenvolvimento da criatividade são fatores apontados pelos alunos como importantes consequências da aquisição de outras línguas.

Vozes d'África Transatlântica: trajetórias estudantis de Cabo Verde e da Guiné-Bissau - programa de estudantes - convénio de graduação

A presente investigação tem como centralidade a mobilidade internacional de estudantes no caso, a dos africanos oriundos de Cabo Verde e da Guiné-Bissau, participantes do Programa Estudantes-Convênio de Graduação na Universidade Federal do Rio Grande do Norte - UFRN, inserida no fenômeno da internacionalização universitária, acentuada na globalização. O objetivo principal foi analisar o processo de inserção social e acadêmica desses estudantes, com ênfase para os dos cursos de Arquitetura e Urbanismo, Ciências da Computação, Engenharia da Computação e Medicina, nessa Instituição de Ensino Superior - IES. A metodologia foi norteada pela conjugação dos aportes teóricos e metodológicos qualiquantitativa, em que, na primeira, utilizou-se da entrevista semiestrutura dirigida para dezesseis sujeitos; sendo, a metade estudantes e a outra docentes, cuja análise optou-se pela Análise de Discurso (AD) da linha francesa, resultando as formações discursivas: motivações da mobilidade, registro nacional de estrangeiro, identidade étnica, relações étnicoraciais e o PEC-G: seu funcionamento nas práticas sociais na UFRN. Já a pesquisa quantitativa, foi constituída pela aplicação do questionário para o universo de 40 estudantes dos dois grupos e de todas as áreas de conhecimento, cuja interpretação dos dados, recorreu-se ao Programa SPSS. Já, para o recorte dos cursos específicos, foi utilizado, o do Google Doc, os quais, estão expressos em tabelas e gráficos. Os resultados revelaram que essa mobilidade estudantil africana está imersa por um misto de semelhanças e diferenças entre o Brasil e dos Países Africanos de Língua Oficial Poruguesa - PALOP; e mais dos contextos das hierarquias entre os países centrais, semiperiféricos e periféricos, provocadas pelas políticas de reajustes estruturais sobre os serviços educacionais, Sousa (Santos 2008; 2010), que se refletem nas trajetórias acadêmicas temporária no país de acolhimento. Aqui, também, enfrenta as fragilidades e os avanços das políticas públicas do Sistema de Ensino Superior, implementadas pelo governo brasileiro nas IES. Em termos quantitativos para os quatros cursos analisados, em diferentes e curtos períodos, quanto a distribuição de vagas (acesso), formas de desligamentos e conclusão apontaram especificidades. E, grosso modo, o curso de Medicina, apresentou os melhores índices de conclusão, seguidos, pelos de Arquitetura e da Engenharia da Computação. A maioria dos estudantes são do sexo masculino, mais da metade está representada pelos oriundos de Cabo Verde, o restante, pelos da Guiné-Bissau. Enquanto, no curso de Ciências da Computação, foi nula a conclusão de curso, e em função deste histórico de baixo desempenho dos estudantes-convênio PEC-G, teria havido o fechamento de vagas. Mas, verificando-se, que os índices de conclusão nesses cursos, apresentou uma média abaixo dos cursos de graduação da UFRN, nos quais, esses estudantes são minoria ao lado dos afrobrasileiros nas universidades do Brasil.

Do construction companies need to match employees' expectations?

Commitment of employees is relatively low in construction. This problem is exasperated by companies inability to attract, motivate, and retain talent that is then often channelled into other more attractive industrial sectors where the prospects, conditions and rewards are perceived to be much higher. The purpose of this study is thus primarily to develop a generic model to maximise employees' engagement, improve their motivation and increase the retention levels. To achieve this aim, the investigation looks into how perceived employment obligations and expectations impact commitment and through that organisational performance. The study is based on the postulations of Luhmann's theory of social systems with communication viewed as a constitutive element of a social system. Consequently expectations of a particular party in an employment relationship are represented in a communicative space requiring the other party's understanding in order to align expectations of both sides in the relationship. Explicitly, alignment of by an employee perceived manager's expectations determines his/ her commitment to fulfil obligations towards the manager. The result of this first stage of research is a conceptual model developed following the substantial supporting evidence in the literature and it forms the framework for mitigation of low commitment, motivation and retention of employees. The model particularly focuses on factors affecting employees' perceived expectations like reneging, incongruence and the process of communication. In the future the model will be validated using empirical data from a combination of observational and enquiry-based research. Once completed, the model will provide a framework for informing Human Resource Management policies with the aim to improve commitment of employees, increase the levels of retention and consequently improve the performance of construction organisations.

Owls and rabbits: predation against substandard individuals of an easy prey

The interactions among the multiple factors regulating predator-prey relationships make predation a more complex process than previously thought. The degree to which substandard individuals are captured disproportionately seems to be better a function of the difficulty of prey capture than of the hunting techniques (coursing vs. ambushing predators). That is, when the capture and killing of a prey species is easy, substandard individuals will be predated in proportion to their occurrence in the prey population. In the present study, we made use of eagle owls Bubo bubo and their main prey, the rabbit Oryctolagus cuniculus: (a) the brightness of the white tails of rabbits seems to be correlated with the physical condition of individuals, (b) by using the tails of predated rabbits as an index of individual condition, we found that eagle owls seem to prefer substandard individuals (characterized by duller tails), and (c) by using information from continuous radiotracking of 14 individuals, we suggest that the difficulty of rabbit capture could be low. Although the relative benefits of preying on substandard individuals should considerably decrease when a predator is attacking an easy prey, we hypothesise that the eagle owl preference for substandard individuals could be due to the easy detection of poor individuals by a visual cue, the brightness of the rabbit tail. Several elements allow us to believe that this form of visual communication between a prey and one of its main predators could be more widespread than previously thought. In fact: (a) visual signalling plays a relevant role in intraspecific communication in eagle owls and, consequently, visual signals could also play a role in interspecific interactions, and (b) empirical studies showed that signals may inform the predator that it has been perceived, or that the prey is in a sufficiently healthy state to elude the predator.

Redox chemistry and electronic properties of 2,3,5,6-tetrakis(2-pyridyl)pyrazine-bridged diruthenium complexes controlled by N,C,N '-biscyclometalated ligands

To investigate the consequences of cyclometalation for electronic communication in dinuclear ruthenium complexes, a series of 2,3,5,6-tetrakis(2-pyridyl)pyrazine (tppz) bridged diruthenium complexes was prepared and studied. These complexes have a central tppz ligand bridging via nitrogen-to-ruthenium coordination bonds, while each ruthenium atom also binds either a monoanionic, N,C,N'-terdentate 2,6-bis(2'-pyridyl)phenyl (R-N boolean AND C boolean AND N) ligand or a 2,2':6',2 ''-terpyridine (tpy) ligand. The N,C,N'-, that is, biscyclometalation, instead of the latter N,N', N ''-bonding motif significantly changes the electronic properties of the resulting complexes. Starting from well-known [{Ru(tpy)}(2)(mu-tppz)](4+) (tpy = 2,2':2 '',6-terpyridine) ([3](4+)) as a model compound, the complexes [{Ru(R-N boolean AND C boolean AND N)}(mu-tppz){Ru(tpy)}](3+) (R-N boolean AND C(H)boolean AND N = 4-R-1,3-dipyridylbenzene, R = H ([4a](3+)), CO2Me ([4b](3+))), and [{Ru(R-N boolean AND C boolean AND N)}(2)(mu-tppz)](2+), (R = H ([5a](2+)), CO2Me ([5b](2+))) were prepared with one or two N,C,N'-cyclometalated terminal ligands. The oxidation and reduction potentials of cyclometalated [4](3+) and [5](2+) are shifted negatively compared to non-cyclometalated [3](4+), the oxidation processes being affected more significantly. Compared to [3](4+), the electronic spectra of [5](2+) display large bathochromic shifts of the main MLCT transitions in the visible spectral region with low-energy absorptions tailing down to the NIR region. One-electron oxidation of [3](4+) and [5](2+) gives rise to low-energy absorption bands. The comproportionation constants and NIR band shape correspond to delocalized Robin-Day class III compounds. Complexes [4a](3+) (R = H) and [4b](3+) (R = CO2Me) also exhibit strong electronic communication, and notwithstanding the large redox-asymmetry the visible metal-to-ligand charge-transfer absorption is assigned to originate from both metal centers. The potential of the first, ruthenium-based, reversible oxidation process is strongly negatively shifted. On the contrary, the second oxidation is irreversible and cyclometalated ligand-based. Upon one-electron oxidation, a weak and low-energy absorption arises.

Environmental quality and the productive workplace

A good working environment will help to provide the user with a good sense of wellbeing, inspiration and comfort. The main advantages of good environments is in terms of reduced upgrading investment, reduced sickness absence, an optimum level of productivity and improved overall satisfaction. Individuals respond very differently to their environments and research suggests a correlation between worker productivity and well-being, environmental, social and organisational factors. Research shows the occupants who report a high level of dissatisfaction about their job are usually the people who suffer more work and office environment related illnesses which affect their wellbeing, but not always so. Well-being expresses overall satisfaction. There is a connection between dissatisfied staff and low productivity; and a good sense of well-being is very important as it can lead to substantial productivity gain. If the environment is particularly bad people will be dissatisfied irrespective of job satisfaction. This paper describes research showing how environment affects productivity.

A review of the use of demonstration projects to achieve widespread adoption of innovative practices

The UK construction industry has embarked on one of the largest experiments in the implementation of innovative technologies and practices in its history. Following Rethinking Construction[1], generally known as the Egan Report, the Movement for Innovation was established with the aim of using demonstration projects as practical examples of innovation in order to encourage others to follow the example. The number of demonstration projects has exceeded the original plans and more are being added. This paper reviews the approach in terms of the practice of using demonstration projects to achieve widespread take up of innovation, the modifications to the programme and its management and considers future developments to improve its, effectiveness.

Innovative approach to building systems integration problems: Using systems theory, technological forecasting and scenario planning

Building services are worth about 2% GDP and are essential for the effective and efficient operations of the building. It is increasingly recognised that the value of a building is related to the way it supports the client organisation’s ongoing business operations. Building services are central to the functional performance of buildings and provide the necessary conditions for health, well-being, safety and security of the occupants. They frequently comprise several technologically distinct sub-systems and their design and construction requires the involvement of numerous disciplines and trades. Designers and contractors working on the same project are frequently employed by different companies. Materials and equipment is supplied by a diverse range of manufacturers. Facilities managers are responsible for operation of the building service in use. The coordination between these participants is crucially important to achieve optimum performance, but too often is neglected. This leaves room for serious faults. The need for effective integration is important. Modern technology offers increasing opportunities for integrated personal-control systems for lighting, ventilation and security as well as interoperability between systems. Opportunities for a new mode of systems integration are provided by the emergence of PFI/PPP procurements frameworks. This paper attempts to establish how systems integration can be achieved in the process of designing, constructing and operating building services. The essence of the paper therefore is to envisage the emergent organisational responses to the realisation of building services as an interactive systems network.

Making sense of research quality assessment

Purpose – For many academics in UK universities the nature and orientation of their research is overwhelmingly determined by considerations of how that work will be graded in research assessment exercises (RAEs). The grades awarded to work in a particular subject area can have a considerable impact on the individual and their university. There is a need to better understand those factors which may influence these grades. The paper seeks to address this issue. Design/methodology/approach – The paper considers relationships between the grades awarded and the quantitative information provided to the assessment panels for the 1996 and 2001 RAEs for two subject areas, built environment and town and country planning, and for three other subject areas, civil engineering, geography and archaeology, in the 2001 RAE. Findings – A simple model demonstrating strong and consistent relationships is established. RAE performance relates to numbers of research active staff, the production of books and journal papers, numbers of research studentships and graduations, and research income. Important differences between subject areas are identified. Research limitations/implications – Important issues are raised about the extent to which the new assessment methodology to be adopted for the 2008 RAE will capture the essence of good quality research in architecture and built environment. Originality/value – The findings provide a developmental perspective of RAEs and show how, despite a changed methodology, various research activities might be valued in the 2008 RAE. The basis for a methodology for reviewing the credibility of the judgements of panels is proposed.

Effects of active information processing on the understanding of risk information

Two experiments investigated effects of active processing of risk information on participants' understanding and judgments. It was hypothesized that more active processing would lead to better understanding and differences in affective judgments (e.g. increased satisfaction and reduced perceived risk to health). In both experiments participants were given a written scenario about their being prescribed a fictitious medication. This medication was said to cause side effects in 2% of people who took it. Before answering a series of written questions, participants in the active conditions of both experiments were asked to carry out a reflective task (portraying the size of risk on a bar chart in Experiment 1 and answering a reflective question in Experiment 2). The results showed that active participants rated the likelihood of experiencing possible side effects significantly lower than passive participants (Experiment 1), and that active participants were significantly more satisfied with the information and judged perceived risk to health from taking the medication significantly lower than passive participants (Experiment 2). In both experiments, active participants were significantly more correct in their probability and frequency estimates. The studies demonstrate that active processing of risk information leads to improved understanding of the information given. This has important implications for risk communication. In the context of health, better understanding should lead to improved decision-making and health outcomes. Copyright (C) 2004 John Wiley Sons, Ltd.

Mono- and heterodimetallic FeII and RuII complexes based on a novel heteroditopic 4′-{bis(phosphanyl)aryl}-2,2′:6′,2″-terpyridine ligand

In the search for a versatile building block that allows the preparation of heteroditopic tpy-pincer bridging ligands, the synthon 14'-[C6H3(CH2Br)(2)-3,5]-2,2':6',2 ''-terpyridine was synthesized. Facile introduction of diphenylphosphanyl groups in this synthon gave the ligand 14'-[C6H3(CH2PPh2)2-3,5]-2,2':6',2"-terpyridine) ([tpyPC(H)Pj). The asymmetric mononuclear complex [Fe(tpy){tpyPC(H)P}](PF6)(2), prepared by selective coordination of [Fe(tpy)Cl-3] to the tpy moiety of [tpyPC(H)P], was used for the synthesis of the heterodimetallic complex [Fe(tpy)(tpyPCP)Ru(tpy)](PFC,)3, which applies the "complex as ligand" approach. Coordination of the ruthenium centre at the PC(H)P-pincer moiety of [Fe(tpy){tpyPC(H)P}](PF6)(2) has been achieved by applying a transcyclometallation procedure. The ground-state electronic properties of both complexes, investigated by cyclic and square-wave voltammetries and UV/Vis spectroscopy, are discussed and compared with those of [Fe(tPY)(2)](PF6)(2) and [Ru(PCP)(tpy)]Cl, which represent the mononuclear components of the heterodinuclear species. An in situ UV/Vis spectroelectrochemical study was performed in order to localize the oxidation and reduction steps and to gain information about the Fe-II-Ru-II communication in the heterodimetallic system [Fe(tpy)(tpyPCP)Ru(tpy)](PF6)(3) mediated by the bridging ligand [tpyPCP]. Both the voltammetric and spectroelectrochemical results point to only very limited electronic interaction between the metal centres in the ground state.

Virtual reality as a visualisation tool: benefits and constraints

The benefits and applications of virtual reality (VR) in the construction industry have been investigated for almost a decade. However, the practical implementation of VR in the construction industry has yet to reach maturity owing to technical constraints. The need for effective information management presents challenges: both transfer of building data to, and organisation of building information within, the virtual environment require consideration. This paper reviews the applications and benefits of VR in the built environment field and reports on a collaboration between Loughborough University and South Bank University to overcome constraints on the use of the overall VR model for whole lifecycle visualisation. The work at each research centre is concerned with an aspect of information management within VR applications for the built environment, and both data transfer and internal data organisation have been investigated. In this paper, similarities and differences between computer-aided design (CAD) and VR packages are first discussed. Three different approaches to the creation of VR models during the design stage are identified and described, with a view to providing sharing understanding across the interdiscipliary groups involved. The suitable organisation of building information within the virtual environment is then further investigated. This work focused on the visualisation of the degradation of a building, through its lifespan, with the view to provide a visual aid for developing an effective and economic project maintenance programme. Finally consideration is given to the potential of emerging standards to facilitate an integrated use of VR. The convergence towards similar data structures in VR and other construction packages may enable visualisation to be better utilised in the overall lifecycle model.

La comunicazione interculturale

The chapter is about Intercultural communication in Italy (seen from both a sociolinguistic and a pragmatic perspective), and it is structured into four different sections: “Key words/concept”, “Theoretical background”, “Good practice” and “Exercises”. Although based on the most recent research on Intercultural communication, it is addressed to both specialists/scholars and non specialists, as it is meant not only to outline new approaches and interpretations, but also to be regarded as a possible resource by civil servants and operators working with migrants. It is included in a book sponsored by the “Forum Internazionale ed Europeo di Ricerche sull’Immigrazione” (International and European Forum on Migration Research), which gathers contributions on policy, housing, education, health, employment and communication, and it has been widely adopted as a text book in Italian universities and by public institutions.
