The Deconstructed Church: Understanding Emerging Christianity

The Emerging Church Movement (ECM) is a reform movement within Western Christianity that reacts against its roots in conservative evangelicalism by “de-constructing” contemporary expressions of Christianity. Emerging Christians see themselves as overturning out-dated interpretations of the bible, transforming hierarchical religious institutions, and re-orientating Christianity to step outside the walls of church buildings toward working among and serving others in the “real world.”

Drawing on ethnographic observations from emerging congregations, pub churches, neo-monastic communities, conferences, online networks, in-depth interviews, and congregational surveys in the US, UK, and Ireland, this book provides a comprehensive social scientific analysis of the development and significance of the ECM. Emerging Christians are shaping a distinct religious orientation that encourages individualism, deep relationships with others, new ideas around the nature of truth, doubt, and God, and innovations in preaching, worship, Eucharist, and leadership.

Advanced design optimization of cold-formed steel portal frame buildings

The design optimization of cold-formed steel portal frame buildings is considered in this paper. The objective function is based on the cost of the members for the main frame and secondary members (i.e., purlins, girts, and cladding for walls and roofs) per unit area on the plan of the building. A real-coded niching genetic algorithm is used to minimize the cost of the frame and secondary members that are designed on the basis of ultimate limit state. It iis shown that the proposed algorithm shows effective and robust capacity in generating the optimal solution, owing to the population's diversity being maintained by applying the niching method. In the optimal design, the cost of purlins and side rails are shown to account for 25% of the total cost; the main frame members account for 27% of the total cost, claddings for the walls and roofs accounted for 27% of the total cost.

Silicon, the silver bullet for mitigating biotic and abiotic stress, and improving grain quality, in rice?

Adequate silicon fertilization greatly boosts rice yield and mitigates biotic and abiotic stress, and improves grain quality through lowering the content of cadmium and inorganic arsenic. This review on silicon dynamics in rice considers recent advances in our understanding of the role of silicon in rice, and the challenges of maintaining adequate silicon fertility within rice paddy systems. Silicon is increasingly considered as an element required for optimal plant performance, particularly in rice. Plants can survive with very low silicon under laboratory/glasshouse conditions, but this is highly artificial and, thus, silicon can be considered as essential for proper plant function in its environment. Silicon is incorporated into structural components of rice cell walls were it increases cell and tissue rigidity in the plant. Structural silicon provides physical protection to plants against microbial infection and insect attack as well as reducing the quality of the tissue to the predating organisms. The abiotic benefits are due to silicon's effect on overall organ strength. This helps protect against lodging, drought stress, high temperature (through efficient maintenance of transpiration), and photosynthesis by protecting against high UV. Furthermore, silicon also protects the plant from saline stress and against a range of toxic metal stresses (arsenic, cadmium, chromium, copper, nickel and zinc). Added to this, silicon application decreases grain concentrations of various human carcinogens, in particular arsenic, antimony and cadmium. As rice is efficient at stripping bioavailable silicon from the soil, recycling of silicon rich rice straw biomass or addition of inorganic silicon fertilizer, primarily obtained from iron and steel slag, needs careful management. Silicon in the soil may be lost if the silicon-cycle, traditionally achieved via composting of rice straw and returning it to the land, is being broken. As composting of rice straw and incorporation of composted or non-composted straw back to land are resource intensive activities, these activities are declining due to population shifts from the countryside to cities. Processes that accelerate rice straw composting, therefore, need to be identified to aid more efficient use of this resource. In addition, rice genetics may help address declining available silicon in paddy soils: for example by selecting for characteristics during breeding that lead to an increased ability of roots to access recalcitrant silicon sources from soil and/or via selection for traits that aid the maintenance of a high silicon status in shoots. Recent advances in understanding the genetic regulation of silicon uptake and transport by rice plants will aid these goals.

Experimental and discrete element modelling of cohesive iron ore fines

In this study, the behaviour of iron ore fines with varying levels of adhesion was investigated using a confined compression test and a uniaxial test. The uniaxial test was conducted using the semi-automated uniaxial EPT tester in which the cohesive strength of a bulk solid is evaluated from an unconfined compression test following a period of consolidation to a pre-defined vertical stress. The iron ore fines were also tested by measuring both the vertical and circumferential strains on the cylindrical container walls under vertical loading in a separate confined compression tester - the K0 tester, to determine the lateral pressure ratio. Discrete Element Method simulations of both experiments were carried out and the predictions were compared with the experimental observations. A recently developed DEM contact model for cohesive solids, an Elasto-Plastic Adhesive model, was used. This particle contact model uses hysteretic non-linear loading and unloading paths and an adhesion parameter which is a function of the maximum contact overlap. The model parameters for the simulations are phenomenologically based to reproduce the key bulk characteristics exhibited by the solid. The simulation results show a good agreement in capturing the stress history dependent behaviour depicted by the flow function of the cohesive iron ore fines while also providing a reasonably good match for the lateral pressure ratio observed during the confined compression K0 tests. This demonstrates the potential for the DEM model to be used in the simulation of bulk handling applications.

Investigation of thermal resistance and bridging in examples of contemporary and vernacular solid wall architecture

Contemporary architecture has tended to increase envelope insulation levels in an unceasing effort to reduce U-values. Traditional masonry architecture in contrast was devoid of insulation, except for the inherent insulative nature of vernacular materials. Also the consistency of the outer membrane of the building skin diminished any impact due to bridging. In contemporary highly insulated walls bridges are numerous due to the necessity to bind inner and outer structural skins through insulation layers. This paper examines thermal bridging in an example of contemporary façade design and compares it with an example of traditional vernacular architecture currently being researched which is characterized by a lack of bridging elements. Focus is given to heavy weight materials of high thermal mass, which appropriately for passive architecture help moderate fluctuations in internal temperature. In an extensive experimental study samples of highly insulated precast concrete sandwich panels and lime rendered masonry walls are tested in a guarded hot-box. The building construction methods are compared for static and dynamic thermal transmittance, via heat flux and surface temperature differential measurements. Focus is given to the differential heat loss due to the thermal bridging in the sandwich panels and its associated impact on overall heat loss relative to traditional masonry construction.

Experimental analysis of air flow profiles in a double skin facade in a maritime climate

Glazed Double Skin Facades (DSF) offer the potential to improve the performance of all-glass building skins, common to commercial office buildings in which full facade glazing has almost become the standard. Single skin glazing results in increased heating and cooling costs over opaque walls, due to lower thermal resistance of glass, and the increased impact of solar gain through it. However, the performance benefit of DSF technology continues to be questioned and its operation poorly understood, particularly the nature of airflow through the cavity. This paper deals specifically with the experimental analysis of the air flow characteristics in an automated double skin façade. The benefit of the DSF as a thermal buffer, and to limit overheating is evaluated through analysis of an extensive set of parameters including air and surface temperatures at each level in the DSF, airflow readings in the cavity and at the inlet and outlet, solar and wind data, and analytically derived pressure differentials. The temperature and air-flow are monitored in the cavity of a DSF using wireless sensors and hot wire anemometers respectively. Automated louvre operation and building set-points are monitored via the BMS. Thermal stratification and air flow variation during changing weather conditions are shown to effect the performance of the DSF considerably and hence the energy performance of the building. The relative pressure effects due to buoyancy and wind are analysed and quantified. This research aims to developed and validate models of DSFs in the maritime climate, using multi-season data from experimental monitoring. This extensive experimental study provides data for training and validation of models.

Rethinking Prison Disciplinary Processes: A Potential Future for Restorative Justice

The movement for restorative justice (RJ) has struggled with marginalization on the soft end of the criminal justice system where the threat of net widening and iatrogenesis looms large. To realize the full potential of RJ as an alternative philosophy of justice, restorative practices need to expand beyond the world of adolescent and small-level offences into the deeper end of the justice system. Disciplinary hearings inside of adult prisons may be a strategic space to advance this expansion. This paper presents findings from a study of prison discipline in four UK prisons. The findings strongly suggest that in their current form, such disciplinary proceedings are viewed by prisoners as lacking in legitimacy. Although modelled after the adversarial system of the criminal court, the adjudications were instead universally derided as ‘kangaroo courts’, lacking in the basic elements of procedural justice. Based on these findings, we argue that restorative justice interventions may offer a viable redress to these problems of legitimacy which, if successful, would have ramifications that extend well beyond the prison walls.

Autonomic modification of intestinal smooth muscle contractility

Intestinal smooth muscle contracts rhythmically in the absence of nerve and hormonal stimulation because of the activity of pacemaker cells between and within the muscle layers. This means that the autonomic nervous system modifies rather than initiates intestinal contractions. The practical described here gives students an opportunity to observe this spontaneous activity and its modification by agents associated with parasympathetic and sympathetic nerve activity. A section of the rabbit small intestine is suspended in an organ bath, and the use of a pressure transducer and data-acquisition software allows the measurement of tension generated by the smooth muscle of intestinal walls. The application of the parasympathetic neurotransmitter ACh at varying concentrations allows students to observe an increase in intestinal smooth muscle tone with increasing concentrations of this muscarinic receptor agonist. Construction of a concentration-effect curve allows students to calculate an EC50 value for ACh and consider some basic concepts surrounding receptor occupancy and activation. Application of the hormone epinephrine to the precontracted intestine allows students to observe the inhibitory effects associated with sympathetic nerve activation. Introduction of the drug atropine to the preparation before a maximal concentration of ACh is applied allows students to observe the inhibitory effect of a competitive antagonist on the physiological response to a receptor agonist. The final experiment involves the observation of the depolarizing effect of K+ on smooth muscle. Students are also invited to consider why the drugs atropine, codeine, loperamide, and botulinum toxin have medicinal uses in the management of gastrointestinal problems.

Parker Morris and the Fordist House

6.00 pm. If people like watching T.V. while they are eating their evening meal, space for a low table is needed (Ministry of Housing and Local Government, Space in the Home, 1963, p. 4).

This paper re-examines the 1961 Parker Morris report on housing standards in Britain. It explores the origins, scope, text and iconography of the report and suggests that these not only express a particularly modernist conception of space but one which presupposed very specific economic conditions and geographies.

Also known as Homes for Today and Tomorrow Parker Morris attempted, through the application of scientific principles, to define the minimum living space standards needed to accommodate household activities. But while early modernist research into notions of existenzminimum were the work of avant-garde architects and thinkers, Homes for Today and Tomorrow and its sister design manual Space in the Home were commissioned by the British State. This normalization of scientific enquiry into space can be considered not only as a response to new conditions in the mass production of housing – economies of scale, prefabrication, system-building and modular coordination – but also to the post-war boom in consumer goods. In this, it is suggested that the domestic interior was assigned a key role as a privileged site of mass consumption as the production and micro-management of space in Britain became integral to the development of a planned national economy underpinned by Fordist principles. Parker Morris, therefore, sought to accommodate activities which were pre-determined not so much by traditional social or familial ties but rather by recently introduced commodities such as the television set, white goods, table tennis tables and train sets. This relationship between the domestic interior and the national economy are emblematized by the series of placeless and scale-less diagrams executed by Gordon Cullen in Space in the Home. Here, walls dissolve as space flows from inside to outside in a homogenized and ephemeral landscape whose limits are perhaps only the boundaries of the nation state and the circuits of capital.

In Britain, Parker Morris was the last explicit State-sponsored attempt to prescribe a normative spatial programme for national living. The calm neutral efficiency of family-life expressed in its diagrams was almost immediately problematised by the rise of 1960s counter-culture, the feminist movement and the oil crisis of 1972 which altered perhaps forever the spatial, temporal and economic conditions it had taken for granted. The debate on space-standards, however, continues.

John Thompson: Seeing through China

In 1848, Karl Marx predicted that a flow of cheap commodities would be the heavy artillery which would batter down all Chinese walls and open up the country to the west (Marx, 1978, p. 477). The Scottish photographer John Thomson (1837-1921) was both chronicler of and participant in the early moments of this process. Thomson was a commercial photographer who first arrived in the Far East in 1862. He earned the moniker of 'China' in a decade-long stay during which he photographed what he considered to be the key aspects of its culture and landscape. In this body of work, Illustrations of China and its People (first published in 1874) is perhaps the most comprehensive. It explores, through two hundred photographs and accompanying texts, a series of phenomena from the macro-scale of landscape, infrastructure and industry to the smaller scales of streetscapes, domestic spaces, individual portraits, and other details of everyday life. Despite his own description of the volumes as encyclopedic, Illustrations is geographically quite limited. Thomson's explorations into the hinterland proceed up the country’s principal rivers from those coastal ports which had already been wrested into western hands during the Opium Wars (of the 1840s) and subsequently opened up to trade. This is perhaps one of the reasons why Illustrations has been described as an explicitly colonial text, a guide-book for the prospective settler whose content offered the strategic knowledge of land, culture and natural resources necessary if the territorial advantages of the coastal periphery were to extended to the interior (Jeffrey, 1981, p. 64). It can also be argued, however, that Thomson’s volume offered justification for a potential colonial presence. Faced with a civilization whose history was as sophisticated as the west, it depicts a culture that is static and moribund, its addiction to traditional values an impediment to progress. While this is perhaps most explicit in the texts of Illustrations of China, it can also be seen in the images whose uniform chemical rendering also serves to make an essentially diverse culture seem homogenous. Yet it is these images that distinguish Illustrations from previous attempts to collate China’s culture and landscape. Here, the mechanical precision of his camera captures a reality that often subverts the colonial narrative, confounding stereotypes as Thomson’s mass-produced images allow another China to emerge.

The influence of water motion on the growth rate of the kelp Laminaria digitata

The shallow water kelp Laminaria digitata, abundant in coastal zones of the North Atlantic, is exposed to a range of hydrodynamic environments that makes it ideal for assessing the role of water motion on their growth rate. Here we quantify the growth of L. digitata, as a factor of blade and stipe elongation, at sites adjacent to Strangford Lough, Northern Ireland under different hydrodynamic conditions over a one year period. A modelling approach was used to numerically determine both the temporal and spatial variability of the hydrodynamic environment. Ambient seawater nutrient concentrations, temperature and irradiance were measured as well as the internal nutrient status of the L. digitata populations. Kelp populations growing in the greatest and lowest water motion showed the lowest growth rates. Differences observed in growth rate could not be attributed to seawater nutrient availability, temperature or light. The internal nutrient status also suggested no influence on the observed differences in growth rate. Therefore if there are minimal differences in light, temperature and nutrients between sites, then populations of L. digitata exposed to different water motions are likely to exhibit different growth rates. It is suggested that the growth rate differences observed were a function of water motion with the possibility that, in response to the hydrodynamic forces experienced by the algal cells, L. digitata kelps in the high energy environments were putting more energy into strengthening cell walls rather than blade elongation

The Promise of Peace:Revisiting the Northern Irish Model

The Northern Ireland peace process is often eulogized as a successful model of conflict transformation. Although the process exhibited many of the problems that beset other societies seeking to move from conflict to a negotiated peace (including disagreements over the functioning of institutions and the meanings of cultural symbols, unresolved issues relating to the effects of political violence on victims and survivors and society at large; and the residual presence of violent and political ‘spoiler’ groups), the resilience of political dialogue has proven remarkable.
This collection revisits the promise of ‘a truly historic opportunity for a new beginning’ a decade and a half on from the signing of the Belfast/Good Friday Agreement in 1998. The book will bring together academics from across a number of disciplines, including management and organizational behaviour, law, politics, sociology, archaeology and literature.

The different contributions aim to assess what impact it has made in the legal, policy, and institutional areas it specifically targeted: political reform, human rights and equality provision, working through legacies of the past (including police reform, prisoner release and victims' rights) and the building of new relationships within the island of Ireland and between Ireland and Britain. With the emergence of first-time voters who had no direct experience of the violence the book explores what the Agreement offers for future generations.

The book is the culmination of a 12-month research project sponsored by the British Academy and Leverhulme that addressed the following aspects of the peace process:
Peace walls: The euphemistically named peace walls remain one of the most visible reminders of Northern Ireland’s divisions and they are famously the only material manifestations of the conflict that have grown in number and extent since the 1998 Agreement. They were originally placed between antagonistic neighbouring communities – often at their request – at times of heightened tensions. Research under this theme explored the lack of ongoing engagement with their continuing presences, evolving meanings and impact on the communities that reside beside them needs to be overtly addressed.
Cultural division: Cultural differences have often been seen as lying at the heart of the ‘Irish problem’. Despite this, art and artists have increasingly been seen as having the potential to develop new discourses. Research explored the following questions: What role can the arts play in re-imagining the spaces opened up by the promises of the 1998 Agreement? What implication does the confrontation with the legacies of conflict have for artistic practices? What impact do the arts have on constructions of identity, on narratives of history, and on electoral politics?
Institutional transformation: This strand of research explored the significance of the process of organizational change which followed the establishment of the 1998 on political and other public policy institutions such as the police and prison services. It suggested that the experience and lessons learned from such periods of transition have much to contribute to how Northern Ireland begins to address political polarization in other areas of public service infrastructure, chiefly around the sectarian monoliths of education and housing.
Working through the past: ‘Legacy’ issues have gained increasing prominence since 1998: issues to do with public symbolism (particularly relating to the flying of flags and parading), defining victimhood, securing victims’ rights, recovery of the ‘disappeared’, reintegrating ex- prisoners back into society, and the possibilities for truth recovery and reconciliation have all acquired salient and emotive force. Although the 1998 Agreement promised to ‘honour the dead’ through a ‘new beginning’, it is increasingly unclear as to whether an agreed narrative about the past is possible – or even worthwhile pursuing. Research under this theme looked at the complex relationship between memory, commemoration and violence; how commemorative events are performed, organized, policed and represented. It also addressed the fraught issue of how to come to terms with Northern Ireland’s divided and bloodied past.

The editors are in the process of guiding contributors to adapt their papers, which were presented to a series of workshops on the above themes, to the purposes of the book. In particular, the contributors will be guided to focus on the related aims of assessing the extent of change that has occurred and providing an assessment of what remains to be done. To that end, contributors are asked to engage directly with the questions that close the ‘Introduction’, namely: To what extent has the ‘promise’ of the 1998 Agreement been fulfilled? To what extent has the 1998 Agreement given rise to forms of exclusion? To what extent has the 1998 Agreement shaped new forms of debate, dispute and engagement? In the absence of that guidance having been sent out yet, the outlines below are, for the time being, the abstracts of their original papers.

Identity of a Tilapia Pheromone Released by Dominant Males that Primes Females for Reproduction

Knowledge of the chemical identity and role of urinary pheromones in fish is scarce, yet it is necessary in order to understand the integration of multiple senses in adaptive responses and the evolution of chemical communication [1]. In nature, Mozambique tilapia (Oreochromis mossambicus) males form hierarchies, and females mate preferentially with dominant territorial males, which they visit in aggregations or leks [2]. Dominant males have thicker urinary bladder muscular walls than subordinates or females and store large volumes of urine, which they release at increased frequency in the presence of subordinate males or preovulatory, but not postspawned, females [3–5]. Females exposed to dominant-male urine augment their release of the oocyte maturation-inducing steroid 17α,20β-dihydroxypregn-4-en-3-one (17,20β-P) [6]. Here we isolate and identify a male Mozambique tilapia urinary sex pheromone as two epimeric (20α- and 20β-) pregnanetriol 3-glucuronates. We show that both males and females have high olfactory sensitivity to the two steroids, which cross-adapt upon stimulation. Females exposed to both steroids show a rapid, 10-fold increase in production of 17,20β-P. Thus, the identified urinary steroids prime the female endocrine system to accelerate oocyte maturation and possibly promote spawning synchrony. Tilapia are globally important as a food source but are also invasive species, with devastating impact on local freshwater ecosystems [7, 8]. Identifying the chemical cues that mediate reproduction may lead to the development of tools for population control [9–11].

Extracção supercrítica de óleo de grainha de uva combinada com pré-tratamentos enzimáticos

Neste trabalho estudou-se a extracção supercrítica do óleo de grainha de uva, usando dióxido de carbono, e combinou-se este processo com um prétratamento enzimático da semente para aumentar o rendimento global da extracção. A qualidade dos extractos obtidos foi avaliada pelo seu conteúdo em triacilglicerídeos, perfil de ácidos gordos e capacidade antioxidante. Realizaram-se também alguns estudos exploratórios sobre a aplicação de um pré-tratamento de alta pressão (HPP) à grainha da uva. Adicionalmente, efectuou-se o estudo da extracção, fraccionamento e caracterização estrutural das procianidinas da grainha da uva, bem como a avaliação da sua capacidade antioxidante. A extracção de procianidinas da grainha da uva foi efectuada sequencialmente com metanol e acetona/água, tendo sido posteriormente fraccionadas por adição sucessiva de misturas metanol/clorofórmio progressivamente mais concentradas em clorofórmio. A caracterização das procianidinas foi feita por HPLC-UV e LC–MS, antes e depois de sujeitar as amostras a uma tiólise, e também por ESI-MS e ESI-MS/MS. Este estudo permitiu reportar, pela primeira vez, a ocorrência de procianidinas do tipo-A galoiladas na grainha da uva. Os resultados de HPLC-UV permitiram determinar o grau médio de polimerização das procianidinas e a sua composição monomérica em (+)- catequina, (-)-epicatequina e (-)-epicatequina-O-galato. Mostrou-se que a (+)- catequina é o flavan-3-ol terminal mais abundante e a (-)-epicatequina predomina largamente como unidade de extensão. No caso de procianidinas do tipo A, a ligação interflavânica C2-C7 encontra-se essencialmente nas unidades terminais. O grau médio de polimerização das diversas fracções varia entre 1.0 e 10.8. A sua capacidade antioxidante, medida pelo método espectrofotométrico de DPPH•, mostrou-se ser equivalente à de uma amostra comercial de (+)-catequina usada como referência. A partir dos graus médios de polimerização experimentais e das análises de FTIR das fracções correspondentes foi possível obter um modelo preditivo O-PLS com apenas uma variável latente. O pré-tratamento enzimático justificou-se pelo conhecimento existente acerca do uso de enzimas específicas que destroem parcialmente as paredes celulares. Atendendo à composição das paredes celulares da grainha da uva preparou-se uma suspensão contendo protease, xilanase, pectinase e celulase. Para determinar as condições experimentais do pré-tratamento que maximizam o rendimento da extracção, estudou-se o efeito do tempo de reacção, temperatura, pH, diâmetro médio das partículas de grainha moída e a concentração das enzimas. Os incrementos do rendimento da extracção de óleo observados atingiram 163.2%. O estudo da extracção supercrítica (SFE) do óleo da grainha de uva tratada e não-tratada permitiu obter as curvas de extracção correspondentes, bem com analisar a influência das condições operatórias sobre o seu andamento. Montou-se uma instalação laboratorial onde se realizaram experiências com dióxido de carbono a 160, 180, 200 e 220 bar e temperaturas de 313.15 e 323.15 K. Os rendimentos obtidos por SFE foram semelhantes aos de Soxhlet com n-hexano. As curvas de extracção medidas compreendem um primeiro período de extracção, onde se remove cerca de 92-97% do óleo disponível, e um segundo período, essencialmente difusional, com pouco impacto no rendimento final. Os vários extractos recolhidos e o óleo global obtido foram caracterizados para avaliar a sua qualidade e relacioná-la com as condições operatórias de SFE. Determinaram-se o conteúdo total em triacilglicerídeos, o seu perfil de ácidos gordos e a capacidade antioxidante (AOC). Os resultados mostraram que a AOC aumenta com a elevação da pressão e, acentuadamente, com o acréscimo da temperatura. Ao longo da curva de extracção, a AOC é mais pronunciada nos extractos iniciais, nomeadamente nos primeiros 30 a 40% da extracção. A modelação efectuada considerou que o óleo extractável se reparte entre células rompidas, predominantes na periferia da semente, e células intactas, mais interiores. Admitiu-se que o transporte de massa ocorre em série, i.e. das células intactas para as rompidas e destas para o solvente; mostrou-se que a dispersão axial era desprezável. Os balanços materiais à fase fluida e aos volumes de células rompidas e intactas, combinados com os fluxos interno, externo e a relação de equilíbrio foram resolvidos numericamente pelo método das linhas combinado com diferenças finitas atrasadas. O modelo reproduziu bem as curvas experimentais e permitiu simular curvas de eluição e os três perfis de concentração no leito.

Aprendizagem e representações da língua portuguesa por lusodescendentes

O papel da língua portuguesa (LP) em contexto migratório não tem ocupado as agendas investigativas; os estudos existentes não focam a natureza da LP dentro das próprias Associações nem a forma como elas colidem ou são consistentes com as representações dos membros das comunidades e com as representações dos professores e lusodescendentes que circulam dentro das próprias Associações. Neste estudo, colocamos o enfoque no ensino-aprendizagem da LP em contexto associativo em França (região parisiense) - mais concretamente, na transmissão de uma história e de uma língua ao longo de três gerações de lusodescendentes, tendo como referência um território de origem – real ou imaginário. Visamos, em particular, mais em concreto, mostrar como a LP, em contacto com outra língua, evolui de forma mais ou menos (des)equilibrada, criando um sistema linguístico híbrido que o ensino-aprendizagem, em contexto alargado, procura preencher. As relações entre práticas langagières e processos de identificação dos jovens da região parisiense foram analisadas na dialéctica do Mesmo e do Outro com o principal intuito de problematizar a forma como os lusodescendentes vivem as representações linguísticas de (des)valorização que o Outro concebe e lhes reenvia. Os dois pólos de referência identitária – o país de origem da família e a França – parecem atrair-se e repelir-se. Para além disso, da análise das referidas práticas langagières, sobressai um bricolage identitário e linguístico permanente, que se acomoda a uma vivência por vezes difícil de assumir. Procedemos à identificação dos diferentes factores: o estatuto da LP em contexto associativo e as suas dimensões ideológicas; os objectivos do ensino-aprendizagem; o perfil linguístico do lusodescendente e a construção do conhecimento profissional dos professores que aí leccionam, que informa e fundamenta as suas práticas, o que vem configurar um processo de elevada complexidade. No âmbito desta investigação mista (qualitativa e quantitativa), levada a cabo, desde 2003, é, assim, nossa intenção, evidenciar a produtividade da investigação sobre esta temática, no sentido de problematizar a consciencialização do ensino-aprendizagem da LP. Como conclusões principais salientamos o papel inquestionavelmente relevante das Associações no desenvolvimento das competências de compreensão e comunicação em LP, mas que carecem de reconhecimento e de apoio orçamental. Estas são objecto de diversas polémicas, acusadas de serem a causa do encerramento de turmas de português no sistema educativo oficial francês e catalogadas de exclusão e isolamento. Este ensino-aprendizagem quer valorizar a partilha de um contexto sociocultural que permite aos lusodescendentes a interacção e a comunicação como também uma certa valorização da identidade cultural portuguesa extra muros. As Associações trabalham a motivação dos lusodescendentes para que estes não abandonem nem a língua nem a cultura. Terminamos procurando, de algum modo, dar um contributo, quanto ao ensino da LP, na valorização e promoção do seu ensino nas Comunidades.
