Inclusion, Participation and the Emergence of British Chinese Websites

Previous work has drawn attention to the relative absence of British Chinese voices in public culture. No one is more aware of this invisibility than British-born Chinese people themselves. Since 2000 the emergence of Internet discussion sites produced by British Chinese young people has provided an important forum for many of them to grapple with questions concerning their identities, experiences and status in Britain. In this paper we explore the ways in which Internet usage by British-born Chinese people has facilitated forms of self-expression, collective identity production and social and political action. This examination of British Chinese websites raises important questions about inclusion and exclusion, citizenship, participation and the development of a sense of belonging in Britain, issues which are usually overlooked in relation to a group which appears to be well integrated and successful in higher education.

The Return of Institutions. On the Latest Change in the Research on Social and Economic Development

The paper describes the latest change in the research on social and economic development of states. This change is characterized mainly by a strong emphasis put on the role of institutions as key instruments of reducing the development gap between countries. It is argued that in the years after 1989 institutions have disappeared from mainstream academia and major intellectual debates because of: (1) the widespread belief in global convergence of capitalism and (2) the modernization theory which prevailed in the social science in the 1990s. The article indicates that institutions were once again brought into focus as a result of (1) a wider debate about the institutional sources of growth and development sparked by Acemoglu and Robinson’s Why Nations Fail, (2) the beginning of the global economic crisis of 2008 triggered by the fall of American investment bank Lehman Brothers (3) diversified consequences of the economic crisis seen all over Europe and the USA which illustrate (4) the institutional varieties of capitalism.

Relatório de Estágio

O presente relatório de estágio afigura-se como o produto final de um 2.º ciclo de estudos no mestrado profissionalizante em Ensino do 1.º e 2º Ciclo do Ensino Básico, materializando-se na unidade curricular de Integração Curricular: Prática Educativa e Relatório de Estágio. Este documento constitui a evidência do percurso individual de formação da mestranda através da fundamentação e contextualização das opções realizadas em contexto de prática educativa e numa perspetiva teórica, procurando uma articulação entre estas duas dimensões. Em termos estruturais este relatório obedece às normas institucionais e inicia-se por um enquadramento teórico e legal, numa perspetiva académica e profissional, em que se mobilizam os conhecimentos adquiridos ao longo dos anos de formação e que sustentaram a componente prática da unidade curricular. Esta componente surge, desta forma, como uma oportunidade de colocar em prática os conhecimentos adquiridos ao longo da formação académica. Numa segunda parte, retrata-se, refletida e sustentadamente, as experiências educativas vivenciadas em contexto de estágio, em diferentes dimensões. O processo cíclico de observação, ação e reflexão pós-ação, que caracterizou a prática educativa e que permitiu refletir sobre a ação, tendo em vista uma melhoria efetiva, é também objeto de análise. Em conjugação com o processo de supervisão que orientou toda a prática, destaca-se a colaboração entre a mestranda e os professores cooperantes que a acompanharam assim como a partilha de saberes entre o grupo de estágio e de onde resultou a postura crítica-reflexiva e consciente de orientações fundamentais para o desenvolvimento pessoal e profissional da professora em formação.

Partnerships in teacher education - going beyond the rhetoric, with reference to the Norwegian context

Teacher education plays a central role in education and relates to various stakeholders of education. Currently, teacher education is not perceived as the sole responsibility of higher education institutions, and they are expected to work closely together with other partners. In this paper, the concept of ‘partnership’ is defined and mutual benefits and challenges in partnerships with disciplines and institutions beyond teacher education programs are briefly discussed. Issues related to partnerships with students are addressed, and the last part of the paper discusses the partnership between teacher education and the practice field with examples from Norway. Three models illustrating such partnerships are described. The central argument of the paper is that partnerships in teacher education need to go beyond rhetoric. (DIPF/Orig.)

DEVELOPMENT OF PRECIPITATION HARDENABLE AL-SC-ZR-HF QUATERNARY ALLOYS THROUGH THERMODYNAMIC MODELING, AND ROOM-TEMPERATURE AND ELEVATED TEMPERATURE HARDNESS

Aluminum alloyed with small atomic fractions of Sc, Zr, and Hf has been shown to exhibit high temperature microstructural stability that may improve high temperature mechanical behavior. These quaternary alloys were designed using thermodynamic modeling to increase the volume fraction of precipitated tri-aluminide phases to improve thermal stability. When aged during a multi-step, isochronal heat treatment, two compositions showed a secondary room-temperature hardness peak up to 700 MPa at 450°C. Elevated temperature hardness profiles also indicated an increase in hardness from 200-300°C, attributed to the precipitation of Al3Sc, however, no secondary hardness response was observed from the Al3Zr or Al3Hf phases in this alloy.

Development of a Coupling Model for Fluid-Structure Interaction using the Mesh-free Finite Element Method and the Lattice Boltzmann Method

In the presented thesis work, the meshfree method with distance fields was coupled with the lattice Boltzmann method to obtain solutions of fluid-structure interaction problems. The thesis work involved development and implementation of numerical algorithms, data structure, and software. Numerical and computational properties of the coupling algorithm combining the meshfree method with distance fields and the lattice Boltzmann method were investigated. Convergence and accuracy of the methodology was validated by analytical solutions. The research was focused on fluid-structure interaction solutions in complex, mesh-resistant domains as both the lattice Boltzmann method and the meshfree method with distance fields are particularly adept in these situations. Furthermore, the fluid solution provided by the lattice Boltzmann method is massively scalable, allowing extensive use of cutting edge parallel computing resources to accelerate this phase of the solution process. The meshfree method with distance fields allows for exact satisfaction of boundary conditions making it possible to exactly capture the effects of the fluid field on the solid structure.

Conflict resolution strategies : influence of organizational and professional commitment nurses

Introduction: The changes in the health area and the set of structural changes in the nursing profession and career interfere in the dynamics and stability of the future of the nurses. Objectives: To study the influence of organizational and professional commitment of the nurses in the strategies of conflict resolution. Methods: This is a quantitative, transversal and non-experimental research, following a descriptive-correlational way. Data were obtained by applying a questionnaire to nurses that work on different types of Primary Health Care Units. As measuring instruments we used three scales that grouped a total of nine subscales used to evaluate: the organizational commitment, the professional commitment and the strategies of conflict resolution. Results: The majority of nurses present moderate scores of organizational and Professional commitment with higher affective commitment to the normative commitment or instrumental commitment and feel that nursing is an interesting and challenging profession, but personal and social perception of nursing relevance is moderately weak. Nurses adopt the domination conflict resolution strategies and accommodation over the head and less integrative strategies and commitment. With subordinates more nurses adopt the avoidance strategy. When the conflictual situation arises with colleagues more endow the integrative strategies and commitment and less domination strategy. The organizational and professional commitment is significantly associated with some solving strategies conflict adopted by nurses as the conflictual situation arises with the boss, with subordinates or colleagues. Some dimensions of organizational commitment and professional foretell to significantly shape the adoption of conflict resolution strategy adopted.

Keys on the Formation and Human Development in Pedagogy

This paper is based on the experiences of the author, who has worked in the various levels of the Venezuelan educational system. This has been a very important platform to understand the ideas of education and human development within the Venezuelan institutionality in the educational field. The idea of education that we have, as teachers, should be rethought in order to consider the personal stories of those who share with us their time, interests and willingness: children, young people or adults, all with particular identities, differences and coincidences. The teachers, the schools and the State cannot consider an education for someone they do not know. In this sense, we provide some reflections resulting from our ethnographic work, based on the school life, interviews, class analysis, observations, and stories, among others. Our thoughts are classified as formation, hope, dialogue, attitude, and school life.

Development of thermochemiluminescence-based sensitive probes: synthesis, optimization, and characterization of c2- and c7-substituted acridine-containing 1,2-dioxetanes

After initial efforts in the late 1980s, the interest in thermochemiluminescence (TCL) as an effective detection technique has gradually faded due to some drawbacks, such as the high temperatures required to trigger the light emission and the relatively low intensities, which determined a poor sensitivity. Recent advances made with the adoption of variably functionalized 1,2-dioxetanes as innovative luminophores, have proved to be a promising approach for the development of reagentless and ultrasensitive detection methods exploitable in biosensors by using TCL compounds as labels, as either single molecules or included in modified nanoparticles. In this PhD Thesis, a novel class of N-substituted acridine-containing 1,2-dioxetanes was designed, synthesized, and characterized as universal TCL probes endowed with optimal emission-triggering temperatures and higher detectability particularly useful in bioanalytical assays. The different decorations introduced by the insertion of both electron donating (EDGs) and electron withdrawing groups (EWGs) at the 2- and 7-positions of acridine fluorophore was found to profoundly affect the photophysical properties and the activation parameters of the final 1,2-dioxetane products. Challenges in the synthesis of 1,2-dioxetanes were tackled with the recourse to continuous flow photochemistry to achieve the target parent compound in high yields, short reaction time, and easy scalability. Computational studies were also carried out to predict the olefins reactivity in the crucial photooxygenation reaction as well as the final products stability. The preliminary application of TCL prototype molecule has been performed in HaCaT cell lines showing the ability of these molecules to be detected in real biological samples and cell-based assays. Finally, attempts on the characterization of 1,2-dioxetanes in different environments (solid state, optical glue and nanosystems) and the development of bioconjugated TCL probes will be also presented and discussed.

Development of a Stability-Indicating LC Assay Method for Determination of Chloroquine

A simple and rapid development of a stability-indicating LC method for determination of chloroquine diphosphate in the presence of its hydrolysis, oxidative and photolysis degradation products is described. Stress testing showed that chloroquine diphosphate was degraded under basic conditions and by photolytic treatment but was stable under the other stress conditions investigated. Separation of the drug from its degradation products was achieved with a Nova Pack C18 column, 0.01 M PIC B7 and acetonitrile (40:60 v/v) pH 3.6, as mobile phase. Response was linear over the range 0.08-5.70 mu g mL(-1) (r = 0.996), with limits of detection and quantification (LOD and LOQ) of 0.17 and 0.35 mu g mL(-1), respectively.

The effect of the aged garlic extract, 'Kyolic', on the development of experimental atherosclerosis

The aged garlic extract 'Kyolic' lowers serum cholesterol levels in humans and experimental animals and thus is presumed to have a protective effect against atherosclerosis. However, to date no studies have examined the effect of this substance on the actual development of the disease. In the present study, the right carotid artery of 24 rabbits was de-endothelialized by balloon catheterisation in order to produce a myointimal thickening. After 2 weeks the rabbits were randomly assigned to four groups: Group I received a standard diet; Group II received the standard diet supplemented with 800 mu 1/kg body weight/day 'Kyolic'; Group III received a 1% cholesterol supplemented standard diet; and Group IV received a 1% cholesterol supplemented standard diet plus 'Kyolic'. After 6 weeks, the cholesterol diet caused a 6-fold increase in serum cholesterol level (Group III; 6.4 +/- 0.6 mmol/1) compared to normal diet (Group I; 1.2 +/- 0.4 mmol/1) (P < 0.05) with only a minor, non-significant reduction seen by the addition of 'Kyolic' (Group IV; 6.2 +/- 0.7 mmol/l). Group III rabbits developed fatty streak lesions covering approximately 70 +/- 8% of the surface area of the thoracic aorta, which was significantly reduced to 25 +/- 3% in the 'Kyolic'-treated Group IV. No lesions were present in Groups I and II. The hypercholesterolaemic diet caused an increase in aortic arch cholesterol (2.1 +/- 0.1 mg cholesterol/g tissue) which was significantly reduced by 'Kyolic' supplementation (1.7 +/- 0.2 mg cholesterol/g tissue) (P < 0.05). 'Kyolic' significantly inhibited the development of thickened, lipid-filled lesions in the pre-formed neointimas produced by balloon-catheter injury of the right carotid artery in cholesterol-fed rabbits (intima as percent of artery wall, Group III 42.6 +/- 6.5% versus Group IV 23.8 +/- 2.3%, P < 0.01), but had little effect in rabbits on a standard diet (Group II 18.4 +/- 5.0% versus Group I 16.7 +/- 2.0%). In vitro studies showed that 'Kyolic' has a direct effect on inhibition of smooth muscle proliferation. In conclusion,'Kyolic' treatment reduces fatty streak development, vessel wall cholesterol accumulation and the development of fibro fatty plaques in neointimas of cholesterol-fed rabbits, thus providing protection against the onset of atherosclerosis.

Prenatal diagnosis and natural history of fetuses presenting with pleural effusion

Objective To describe the natural history of fetuses presenting with pleural effusion. Methods Between January 2005 and December 2009 all fetuses diagnosed with pleural effusion were followed up. Fetuses were divided into three groups: I, isolated pleural effusion; II, associated structural anomalies but normal karyotype; and III, chromosomal anomalies. Univariate and multivariate analyses were performed to determine the association between prenatal ultrasound findings and perinatal death. Results Fifty-six fetuses were included in the study. Associated structural or chromosomal anomalies occurred in 75.0% (42/56) of cases. Bilateral pleural effusion and fetal hydrops were associated with each other (p < 0.01) and with perinatal death (p < 0.05). Multivariate analysis indicated that only the presence of associated abnormalities was a statistical determinant of perinatal death (OR, 3.56; 95% CI, 1.48-5.64; p < 0.01). Conclusion Fetal pleural effusion is often associated with other abnormalities, and this association has poor perinatal outcome. Copyright (C) 2011 John Wiley & Sons, Ltd.
