Geospatial Technology in Geography Education
Get PDFThe book is presented as an important starting point for new research in Geography Education (GE) related to the use and application of geospatial technologies (GSTs). For this purpose, the selection of topics was based on central ideas to GE in its relationship with GSTs. The process of geospatial practices (GPs) as the way to learn about GST and with GST marks the central ideas. The sequential presentation of chapters starts with a theoretical approach, followed by the use of GST at different levels in formal education. Teacher education represents an important third topic that analyzes professional development when learning about GST and using GST. The fourth topic focuses on the effectiveness of GST as a tool for teaching and learning in order to assess geospatial thinking in different educational settings. The exploration of trends and recommendations for future development are the final topic of this book. In one sentence, the book touches upon the most important issues on the use of GST in education and includes the most up to date information and discussions related to GST. Although GE is not in the front line of the Information and Communication Technology (ICT) revolution it cannot stay behind as modern education uses technology to prepare better citizens. The importance of this book relies on this basic and fundamental fact
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
The geopolitical fabric of the border regime in the EU-African borderlands
No full textThe Mediterranean Sea has long been a Mare Nostrum but since the decolonisation in the twentieth century it has become a sharp divide between Europe and Africa. In the past decade, the closure of that border has become symbolized by the desperate attempts of migrants from the global South, mainly Sub-Saharan Africa, to cross the Mediterranean on board small pateras to enter European countries without the requested documents to travel legally. The welfare and opportunity differential between North and South, as well as demographic conditions South of the Mediterranean, explain the high potential for migration between the two sides of the border. However the reduction of opportunities for labour migration and tighter border controls have led to an increase in numbers of undocumented residents including visa overstayers, asylum seekers whose application has been rejected and undocumented migrants crossing the border irregularly. This paper shows how migration control has become a central increasingly machine-like as also moral highly dubious geopolitical strategy of the EU in the Mediterranean region and how bordering processes affect these EU-African borderlands
