An ideal learning analytics tool for programming exercises performs the role of a lecturer who monitors the code development, provides customized support and identifies students at risk to drop out. But a reliable prediction and prevention of drop-out is difficult, due to the huge problem space in programming tasks and variety of solutions and programming strategies. The purpose of this paper is to tackle this problem by, first, identifying activity patterns that indicate students at risk; and, second, finding reasons behind specific activity pattern, for identification of instructional interventions that prevent drop-out.

The authors combine two investigation strategies: first, learning analytic techniques (decision trees) are applied on features gathered from students, while completing programming exercises, in order to classify predictors for drop-outs. Second, the authors determine cognitive, motivational and demographic learner characteristics based on a questionnaire. Finally, both parts are related with a correlation analysis.

It was possible to identify generic variables that could predict early and later drop-outs. For students who drop out early, the most relevant variable is the delay time between availability of the assignment and the first login. The correlation analysis indicates a relation with prior programming experience in years and job occupation per week. For students who drop out later in the course, the number of errors within the first assignment is the most relevant predictor, which correlates with prior programming skills.

The findings indicate a relation between activity patterns and learner characteristics. Based on the results, the authors deduce instructional interventions to support students and to prevent drop-outs.

After the end of World War II, Switzerland became a key hub for international commodity traders, even though most of the commodities they were dealing in were sourced from outside of Switzerland and were not meant for Swiss producers, refiners or consumers. The main aim of this chapter is to analyze why Switzerland became the centre for international commodity trading in the Western world. The chapter will especially focus on the period from the 1950s to the end of the 1980s. Given that commodity trading companies throughout history have been notoriously closed to external scrutiny, the chapter by need is mainly based on publicly available material. The chapter utilizes the concept of collective entrepreneurship as an analytical framework to situate the development.

The purpose of this paper is to examine the development of educational leadership, administration and management (EdLAM) research by identifying thematic strands that hallmark key publications and synthesise major research findings and limitations.

This study combines bibliometric and content analysis methods to review 2,347 publications from 15 core EdLAM journals published from 2007 to 2016.

The bibliometric analysis identified five EdLAM thematic strands: school leadership for enhancing students’ academic achievement and teachers’ effectiveness; leadership for educational change, accountability and promoting democratic values; leadership for social justice, equal education and narrowing achievement gaps; principal’s instructional leadership for school improvement; and distributed leadership and its impact on organisational climate and teachers’ attitudes and stress. The content analysis revealed that the EdLAM research from 2007 to 2016 further developed the following research areas: the dynamics between leaders and teachers in leadership work, the potential risks of distributed leadership and the EdLAM challenges brought by the New Public Management and neoliberalism.

This study depicts state-of-the-art EdLAM research. It confirms the combination of bibliometric and content analyses as a useful approach for large-scale review studies. Finally, this review suggests future research directions.

The purpose of this paper is to show how school principals in France spend their work time and when and under what circumstances they deal with school improvement-related matters.

For the study presented in this paper, a combination of quantitative and qualitative methods was used. Five French collèges (secondary schools) from one school district were visited for a week each. Each principal was shadowed, his/her actions and the context were recorded and categorized. The shadowing was conducted using a structured observation approach derived from Mintzberg. In addition semi-structured interviews were conducted with all principals. The data were analyzed following a grounded theory approach.

The results show how principals spend their work time and as well as possible areas of improvement. Among other things, they reveal very fragmented workdays. Most principals put a low emphasis on school improvement and struggle with conflicting expectations (preservation vs innovation). Shared leadership was only observed in one case.

The specificity of the sample limits the possible ranges of interpretation and generalization. Also, it remains unclear whether one week of observation per school is enough to get a reliable estimate of a principal's daily work. There is a need for further empirical studies of the matter.

This paper offers rare insights into the day-to-day work of French school principals. It contributes to the understanding of school leadership practice as well as to the transcultural understanding of school leadership.

According to the principle of equivalence of care, health care in prison has to be of the same standard and quality as in the general population. This study aims to determine the geographic accessibility of dialysis services for older prisoners and the older general population in Switzerland and whether accessibility and availability of dialysis care are equivalent.

Spatial accessibility analysis incorporated four different data types: population data, administrative data, street network data and addresses of prisons and hemodialysis services.

Analysis revealed that the average travel time to the nearest dialysis service was better for prisoners (11.5 min) than for the general population (14.8 min). However, dialysis service for prisoners is hampered by the necessary lead-time in correctional settings, which, ultimately, leads to longer overall access times (36.5 min). Accordingly, the equivalence of dialysis care for older Swiss prisoners is not entirely respected for availability and accessibility.

The strength of the study lies in the combination of ethical principles and the highly tangible results of a spatial accessibility analysis. The ethics-driven empirical analysis provides arguments for policy-makers to review the current practices.

The purpose of this paper is to present a comprehensive literature review that seeks to address modern factors worldwide that are associated with the selection of current procurement methods. The aim is to develop an up-to-date multi-attribute procurement decision-making chart for selecting the appropriate method for the project.

Stage 1 (literature review). The search engines, Emerald; Business Source Premier; Science Direct and Sage were selected to identify journals that have published the most procurement methods-related articles. The search covered the period 1980-2015. Stage 2 (Survey) – after analyzing and appraising the literature, an up-to-date utility decision-making chart for selecting the appropriate procurement method for the project was developed. The chart was based on findings from a survey that included 57 construction professionals and who have demonstrated sound experience about the various procurement options.

There is no one best procurement method for all projects. The selection depends on the nature of the issues or problem at hand. Decision making is not a punctual act. It is often a complex process. Effective decision making also demands quality and timely information, and a careful consideration of alternatives. The multi-attribute decision-making chart presented in this paper has included modern criteria and the client would have end up with different recommendations and consequences should these criteria were not included in priority weightings.

The literature review provides states-of-the art research in the field of procurement methods in construction and the multi-attribute chart is intended to offer decision makers an opportunity to broaden their horizon on the different alternatives procurement routs that could lead to different consequences.

To the best of the authors’ knowledge, very few publications have discussed modern selection criteria for procurement methods in construction under one study. Therefore, this paper has established a platform for scholars and researchers to obtain more useful insights into procurement methods concerns. It has identified research trends in procurement methods which may allow industrial practitioners to appreciate the key concerns in their development of modern concepts and principles such as supply chain, lean construction, sustainability, innovation, value engineering, e-procurement and Building information modeling. The inclusion of these modern criteria will present and add value to procurement decision makers within the construction industry.
