A teaching/learning support tool for introductory programming courses

In This work we present a Web-based tool developed with the aim of reinforcing teaching and learning of introductory programming courses. This tool provides support for teaching and learning. From the teacher's perspective the system introduces important gains with respect to the classical teaching methodology. It reinforces lecture and laboratory sessions, makes it possible to give personalized attention to the student, assesses the degree of participation of the students and most importantly, performs a continuous assessment of the student's progress. From the student's perspective it provides a learning framework, consisting in a help environment and a correction environment, which facilitates their personal work. With this tool students are more motivated to do programming

Comparing meta-analysis and ecological-longitudinal analysis in time-series studies: a case study of the effects of air pollution on mortality in three Spanish cities

The objective of this paper is to introduce a diVerent approach, called the ecological-longitudinal, to carrying out pooled analysis in time series ecological studies. Because it gives a larger number of data points and, hence, increases the statistical power of the analysis, this approach, unlike conventional ones, allows the complementation of aspects such as accommodation of random effect models, of lags, of interaction between pollutants and between pollutants and meteorological variables, that are hardly implemented in conventional approaches. Design—The approach is illustrated by providing quantitative estimates of the short-termeVects of air pollution on mortality in three Spanish cities, Barcelona,Valencia and Vigo, for the period 1992–1994. Because the dependent variable was a count, a Poisson generalised linear model was first specified. Several modelling issues are worth mentioning. Firstly, because the relations between mortality and explanatory variables were nonlinear, cubic splines were used for covariate control, leading to a generalised additive model, GAM. Secondly, the effects of the predictors on the response were allowed to occur with some lag. Thirdly, the residual autocorrelation, because of imperfect control, was controlled for by means of an autoregressive Poisson GAM. Finally, the longitudinal design demanded the consideration of the existence of individual heterogeneity, requiring the consideration of mixed models. Main results—The estimates of the relative risks obtained from the individual analyses varied across cities, particularly those associated with sulphur dioxide. The highest relative risks corresponded to black smoke in Valencia. These estimates were higher than those obtained from the ecological-longitudinal analysis. Relative risks estimated from this latter analysis were practically identical across cities, 1.00638 (95% confidence intervals 1.0002, 1.0011) for a black smoke increase of 10 μg/m3 and 1.00415 (95% CI 1.0001, 1.0007) for a increase of 10 μg/m3 of sulphur dioxide. Because the statistical power is higher than in the individual analysis more interactions were statistically significant,especially those among air pollutants and meteorological variables. Conclusions—Air pollutant levels were related to mortality in the three cities of the study, Barcelona, Valencia and Vigo. These results were consistent with similar studies in other cities, with other multicentric studies and coherent with both, previous individual, for each city, and multicentric studies for all three cities

O círculo da escrita : o texto argumentativo e a consciência (meta)linguística no ensino secundário

O projeto que se apresenta tem por finalidade investigar processos de aperfeiçoamento da competência de escrita do texto argumentativo de alunos do Ensino Secundário. Considerou-se as contribuições convergentes das teorias e técnicas da psicologia cognitiva e de perspetivas sociais da linguagem. Em consequência, associou-se o modelo de revisão de Hayes e Flower (1983; 1980), e de Hayes, Flower, Schriver, Stratman e Carey (1987), ao modelo de análise do discurso de Bronckart (2004; 1996) e à proposta linguística de Adam (2006; 1992). A hipótese que sustenta a investigação é que a consciência (meta)linguística pode facilitar a revisão textual e o aperfeiçoamento da competência de escrita de textos argumentativos, em contexto de Oficina de Escrita. A investigação conjugou duas fases. Na fase intensiva do estudo de caso, os alunos do 11.º ano de Português de uma Escola do Porto progrediram, através de trabalho continuado em Oficina de Escrita. Após a experiência, mesmo alunos com dificuldades revelaram domínio de metalinguagem, mais consciência (meta)linguística na revisão e autorregulação da sua aprendizagem. Na fase extensiva, foi aplicado um inquérito por questionário a uma amostra probabilística de professores do Secundário, igualmente do Porto. Os docentes valorizaram os aspetos supracitados, bem como a leitura de textos argumentativos e o treino do conhecimento explícito da língua. Contudo, em triangulação, as respostas indiciam um ensino centrado no professor, pouco aberto a projetos de escrita, a novas tecnologias e à divulgação de textos à Escola e ao meio. Os resultados indicam que a competência de escrita de textos argumentativos é passível de aperfeiçoamento em Oficina de Escrita, através de interiorização do género textual e aprofundamento da competência (meta)linguística. No contexto do estudo, comprova-se a influência de um treino de escrita inserido em Projetos de Escola, tendo o aluno como sujeito da sua própria aprendizagem, em interação com o meio.

The Totalizing and Silencing Features of Meta‐Narratives and Master Concepts

This paper is organized in the following way. First I deal with Hardt’s and Negri’s Empire; the second section of the paper focuses on Beck´s World Risk Society; the third main section of this paper tackles the functional differentiation argument posed by Buzan and Albert. By way of conclusion, the final section of this paper briefly discusses alternatives to grand-narratives and master concepts.

The growth effects of EU cohesion policy: a meta-analysis. Bruegel Working Paper 2012/14, October 2012

We run a standard income convergence analysis for the last decade and confirm an already established finding in the growth economics literature. EU countries are converging. Regions in Europe are also converging. But, within countries, regional disparities are on the rise. At the same time, there is probably no reason for EU Cohesion Policy to be concerned with what happens inside countries. Ultimately, our data shows that national governments redistribute well across regions, whether they are fiscally centralised or decentralised. It is difficult to establish if Structural and Cohesion Funds play any role in recent growth convergence patterns in Europe. Generally, macroeconomic simulations produce better results than empirical tests. It is thus possible that Structural Funds do not fully realise their potential either because they are not efficiently allocated or are badly managed or are used for the wrong investments, or a combination of all three. The approach to assess the effectiveness of EU funds should be consistent with the rationale behind the post-1988 EU Cohesion Policy. Standard income convergence analysis is certainly not sufficient and should be accompanied by an assessment of the changes in the efficiency of the capital stock in the recipient countries or regions as well as by a more qualitative assessment. EU funds for competitiveness and employment should be allocated by looking at each region’s capital efficiency to maximise growth generating effects or on a pure competitive.

Does the Stockholm Programme matter? The struggles over ownership of AFSJ multiannual programming. CEPS Paper in Liberty and Security No. 51/December 2012

Does the 2009 Stockholm Programme matter? This paper addresses the controversies experienced at EU institutional levels as to ‘who’ should have ownership of the contours of the EU’s policy and legislative multiannual programming in the Area of Freedom, Security and Justice (AFSJ) in a post-Lisbon Treaty landscape. It examines the struggles around the third multiannual programme on the AFSJ, i.e. the Stockholm Programme, and the dilemmas affecting its implementation. The latest affair to emerge relates to the lack of fulfilment by the European Commission of the commitment to provide a mid-term evaluation of the Stockholm Programme’s implementation by mid-2012, as requested by both the Council and the European Parliament. This paper shifts the focus to a broader perspective and raises the following questions: Is the Stockholm Programme actually relevant? What do the discussions behind its implementation tell us about the new institutional dynamics affecting European integration on the AFSJ? Does the EU actually need a new (post- Stockholm) multiannual programme for the period 2015–20? And last, what role should the EP play in legislative and policy programming in order to further strengthen the democratic accountability and legitimacy of the EU’s AFSJ?

The effectiveness of assessment learning objects produced using pair programming

Pair Programming is a technique from the software development method eXtreme Programming (XP) whereby two programmers work closely together to develop a piece of software. A similar approach has been used to develop a set of Assessment Learning Objects (ALO). Three members of academic staff have developed a set of ALOs for a total of three different modules (two with overlapping content). In each case a pair programming approach was taken to the development of the ALO. In addition to demonstrating the efficiency of this approach in terms of staff time spent developing the ALOs, a statistical analysis of the outcomes for students who made use of the ALOs is used to demonstrate the effectiveness of the ALOs produced via this method.
