We present a fully-distributed self-healing algorithm dex that maintains a constant degree expander network in a dynamic setting. To the best of our knowledge, our algorithm provides the first efficient distributed construction of expanders—whose expansion properties holddeterministically—that works even under an all-powerful adaptive adversary that controls the dynamic changes to the network (the adversary has unlimited computational power and knowledge of the entire network state, can decide which nodes join and leave and at what time, and knows the past random choices made by the algorithm). Previous distributed expander constructions typically provide only probabilistic guarantees on the network expansion whichrapidly degrade in a dynamic setting; in particular, the expansion properties can degrade even more rapidly under adversarial insertions and deletions. Our algorithm provides efficient maintenance and incurs a low overhead per insertion/deletion by an adaptive adversary: only O(logn)O(log⁡n) rounds and O(logn)O(log⁡n) messages are needed with high probability (n is the number of nodes currently in the network). The algorithm requires only a constant number of topology changes. Moreover, our algorithm allows for an efficient implementation and maintenance of a distributed hash table on top of dex  with only a constant additional overhead. Our results are a step towards implementing efficient self-healing networks that have guaranteed properties (constant bounded degree and expansion) despite dynamic changes.

The continued use of traditional lecturing across Higher Education as the main teaching and learning approach in many disciplines must be challenged. An increasing number of studies suggest that this approach, compared to more active learning methods, is the least effective. In counterargument, the use of traditional lectures are often justified as necessary given a large student population. By analysing the implementation of a web based broadcasting approach which replaced the traditional lecture within a programming-based module, and thereby removed the student population rationale, it was hoped that the student learning experience would become more active and ultimately enhance learning on the module. The implemented model replaces the traditional approach of students attending an on-campus lecture theatre with a web-based live broadcast approach that focuses on students being active learners rather than passive recipients. Students ‘attend’ by viewing a live broadcast of the lecturer, presented as a talking head, and the lecturer’s desktop, via a web browser. Video and audio communication is primarily from tutor to students, with text-based comments used to provide communication from students to tutor. This approach promotes active learning by allowing student to perform activities on their own computer rather than the passive viewing and listening common encountered in large lecture classes. By analysing this approach over two years (n = 234 students) results indicate that 89.6% of students rated the approach as offering a highly positive learning experience. Comparing student performance across three academic years also indicates a positive change. A small data analytic analysis was conducted into student participation levels and suggests that the student cohort's willingness to engage with the broadcast lectures material is high.

O presente estudo aborda a problemática dos alunos de risco no 2° Ciclo da E.B. 2,3 Ana de Castro Osório, no ano letivo 2004/2005. Na dimensão teórica são referenciadas algumas questões de Organização Escolar (escola reflexiva, autonomia de escola, gestores intermédios e supervisão escolar, o papel do Diretor de Turma, o Projeto Curricular de Escola, algumas linhas orientadoras da política educativa portuguesa, no período em que decorre a elaboração desta investigação) e abordados alguns aspetos gerais dos pré-adolescentes, diversos conceitos de risco, a ação de diversas entidades com competência na área da infância e juventude, o papel da família e a relação desta com a escola. Foi utilizada a metodologia do “Estudo Caso”, no decurso da qual foram analisados documentos internos da escola e elaborados instrumentos de recolha de dados (questionários aplicados aos Alunos e aos seus Diretores de Turma). No tratamento das informações de natureza quantitativa, utilizou-se o programa informático Excel, enquanto nas questões abertas procedeu-se à análise de conteúdo. Em síntese, concluiu-se que: a) um terço dos alunos que frequentava o 2° Ciclo do Ensino Básico, foi sinalizado como “aluno de risco”. Cerca de 75% era do 5° Ano de Escolaridade. Os fatores de risco que mais se destacam são: assiduidade irregular, desmotivação/desinteresse/apatia, défice de atenção e concentração, indisciplina e retenções sucessivas no seu percurso escolar. A família é pouco participativa. b) a resposta curricular dá-se essencialmente dentro da sala de aula; c) a resposta organizacional assenta essencialmente nalgumas medidas previstas nos documentos legislativos. Na última parte do trabalho deixamos expressas as conclusões do estudo mais pormenorizadas, bem como algumas recomendações/sugestões que eventualmente, poderão orientar posteriores investigações. /ABSTRACT - The risk students on a 2nd Cycle of classroom of the E.B. 2, 3 Ana de Castro Osório, during academic year of 2004/2005: A Case study The present study attempts to assess risk students on a 2nd Cycle (Sth and 6th grades) classroom of the “E.B. 2, 3 Ana de Castro Osório” Public School during the academic year of 2004/2005. On a theoretical scale, are assessed some questions about the Classroom Organization (reflexive school, school autonomy, intermediate directors and school supervision, the role of the Class Tutor, the School Curricular Project, some guidelines about the Portuguese education policy during the period when this study took place), and was also assessed some general aspects of preadolescents, risk concepts, and actions taken by various organizations specialized in the areas of childhood and youth, the role of the family and the interrelation between the family and the school. It was used a “Case Study” methodology during which was assessed school documents of this particularly school, and data collecting instruments (Student-applied and Class Tutor-applied questionnaires). On dealing with quantitative data, it was used the Excel application, while for the open questions was assessed by its contents. In brief, it was concluded that: a) a third of students that attended the 2nd Cycle Basic Education schools revealed to be “risk students”. Around 75% of them were 5th grade students. Among the most important risk factors are: irregular attendance, unmotivated/aloofness /apathy, lack of attention and concentration, indiscipline and successive retentions during their education pathway. The family is scarcely participative. b) The curricular response is normally given within the classroom; c) the organizational response lies mostly on some measures included in government documents. On the last part of the paper, we focus on more detailed conclusions, as well as give recommendations/suggestions which may eventually be of guidance to future studies.

A formação do estudante de enfermagem em ensino clínico reveste-se de uma importância singular pelo contacto e vivência de situações em contexto, por lhe proporcionar a aquisição, o desenvolvimento e a consolidação de conhecimentos e competências em vários domínios, assim como de socialização com a profissão. O primeiro ensino clínico pelas actividades em contexto com os profissionais de saúde e os utentes é um período de transição particularmente marcante em termos formativos. Nele frequentemente acontece a ruptura nas suas concepções de formação e de aprendizagem, tornando-se num momento de confronto com uma formação que prepara para a incerteza e imprevisibilidade. Nesta investigação pretendemos compreender o que acontece neste período de aprendizagem, partindo da seguinte questão central de investigação: Que significado tem o primeiro ensino clínico no percurso formativo do estudante de enfermagem? O estudo desta questão exigiu o recurso a uma metodologia de natureza qualitativa baseada na estratégia estudo de caso na sua vertente multicasos. Seleccionámos três casos de estudo respectivamente do 1º, do 2º e 3º anos do Curso de Licenciatura em Enfermagem de três planos de estudos de Escolas Superiores de Enfermagem. O caso é constituído por um grupo de estudantes no primeiro ensino clínico hospitalar, enfermeiros e docentes que os orientam. Desenvolvemos uma etnometodologia em que privilegiámos a observação no terreno com participação directa do investigador, recolha documental, entrevistas etnográficas e semi-estruturadas aos vários intervenientes. A análise da informação reunida processou-se pela análise de conteúdo dos dados obtidos num percurso recursivo entre as várias fontes com apoio do programa informático Nvivo 7. Concluímos que o primeiro ensino clínico: é um período de formação estruturante, com forte impacto pela transição que se opera na postura do estudante perante a aprendizagem, pelas propriedades (trans)formativas que as vivências em contexto encerram, independentemente do ano do Curso em que este acontece; a preparação prévia dos estudantes modeliza os domínios da aprendizagem e a profundidade em que ocorre; aprendem de um modo fragmentado sem conseguirem integrar os vários domínios do conhecimento na acção; os estudantes do 1º ano dão mais significado à destreza e rapidez na realização de intervenções prescritas e à aplicação dos princípios teóricos aprendidos; a orientação dos enfermeiros, tutores e docentes é fundamental na mobilização, para a acção, dos conhecimentos teóricos ou na sua aquisição; a vivência das situações em contexto e o ambiente relacional estão entre os factores mais influentes; a prática orientada com atenção individualizada, questionamento, análise e reflexão em díade supervisor-aluno, são fundamentais no desenvolvimento do pensamento crítico; ser supervisor deve ser assumido pelo docente e pelo enfermeiro ou tutor como um trabalho de articulação e proximidade com e no contexto onde o ensino clínico decorre; a resposta adequada às funções específicas de supervisão exige participação activa de equipas de enfermagem mais preparadas e hierarquicamente apoiadas; o docente pelo conhecimento dos estudantes, dos fins e objectivos da formação, pelos desafios e exigência que coloca tem um papel insubstituível. No percurso da investigação novas questões emergiram nomeadamente no que se prende com: os modelos de articulação entre instituições de saúde e escolares; com a formação dos supervisores e; o papel dos pares no início da aprendizagem dos estudantes em contexto clínico.

The paper explores the issues raised by social work students failing in practice learning settings from the perspective of university tutors, by drawing on existing literature in this area from social work and nursing, as well as findings from a small‐scale empirical qualitative study. The qualitative study was influenced by practitioner‐researcher and practice‐near paradigms; and is based on interviews with twelve social work tutors in England. The findings reveal that tutors are able to articulate the important tasks and functions of their roles when issues of failing students in practice learning settings arise, although the process can be challenging. The challenges include: supporting practice educator and student, concerns about other tutors’ practices, the difficulties in promoting appropriate professional standards and values within higher education contexts and frustrations with practice educators and placements. Only a third of the respondents (four) however, articulated their gate keeping roles and responsibilities although this was not without its difficulties. Given the current reforms in social work education in England at this present time, with greater emphasis on threshold standards at entry level, and at key stages throughout the programme of study, the research is timely in terms of the critical consideration of the tutor role and challenges inherent in promoting appropriate standards.

This paper evaluates an initiative to improve the effectiveness of personal tutoring by embedding it into the curriculum. Structured group tutorials help students make the transition to learning in higher education. These tutorials are delivered within a core module and focus on enabling students to develop study skills, reflect on their learning and plan for their future. The tutor has a role in familiarising students with the practices, norms and skills required for learning at university. The system developed provides a structure and rationale for the interaction of tutors and students, with a clear place and value within the curriculum.

This case study explores the experiences of a group of students (the authors) working as a tutor-less group (TLG) that developed during a web-based MEd programme. We describe the development and life cycle of the TLG, the experiences of the students and the effects on those who continued to work in a tutored environment. Members of the TLG demonstrated high levels of autonomy and group work. The relationship between the TLG and communities of practice is considered.

The second half of the twentieth century has been a time when American Jews have experienced a minimum of prejudice and almost all domains of life have been accessible to them, but it has also been a time of assimilation, of swelling rates of inter-marriage, and of large numbers ignoring their Jewishness completely. Jews have no trouble building synagogues, but they have all sorts of trouble filling them. The quality of Jewish education is perhaps higher than ever before, and the output of Jewish scholarship is overwhelming in its scope and quality, but most American Jews receive a minimum of religious education and can neither read nor comprehend the great corpus of Jewish literature in its Hebrew (or Aramaic) original. This is a time in America when there is no shame in being a Jew, and yet fewer American Jews seem to know what being a Jew means. This book is part of a stocktaking that has been occurring among Jews as the century in which their residence in America was firmly established comes to an end. Grounded in empirical detail, it provides a concise yet analytic evaluation of the meaning of the many studies and surveys of the last four and a half decades. All those who want to know what it means and has meant to be an American Jew will find this volume of interest.
