Crude oil: using a large case to teach introductory economics
Get PDFProblem-based learning is rather labor intensive for teaching staff. In addition, the problem-based structure does not work always optimally in practice. Brainstorming during pre-discussion of tasks becomes very superficial, preparation of the students is far from optimal, and post-discussion is more focused on repeating what is already in the book than on the task being discussed. However, these problems can be solved.This paper discusses a number of innovations in the format of the standard problem-based course. The uses of a large case study and the role of lectures in this, a virtual learning environment, subgroup activities, mind maps in post-discussion, and writing will be discussed. The combination of these innovations increases the efficiency of the group meetings and provides an opportunity to reduce the number of tutor group meetings. The approach that is discussed here is both useful for people who want to introduce problem-based learning as a learning approach in an efficient way as for those who want to improve on an existing problem based learning system.Economics ;

Meat consumption, production and land use : model implementation and scenarios
No full textThis report discusses simulations with the LEITAP model about opportunities to reduce land use as a consequence of changing meat consumption and production. In order to be able to generate plausible simulation results, the LEITAP model had to be adjusted. These changes are discussed in the first part of the report. The next part discusses the simulation experiments and their results. Finally, we discuss shortly where we stand with this type of analyses and what steps could be taken to improve on the quality of this type of analysis
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
