Rural Areas
No full textThis Edited Volume Rural Areas - Development and Transformations is a collection of reviewed and relevant research chapters, offering a comprehensive overview of recent developments in the field of Geography. The book comprises single chapters authored by various researchers and edited by an expert active in this research area. All chapters are complete in themselves but united under a common research study topic. This publication aims at providing a thorough overview of the latest research efforts by international authors in this field of study, and open new possible research paths for further novel developments
Endogenic Processes
No full textEndogenic processes in geology are a function of a body’s internal geodynamic activity.They comprise volcanic, tectonic, and isostatic processes, which shaped the surfaces of all terrestrial planets, the Moon, and basically all other Solar System bodies with solid surfaces that have been observed in some detail.The most recent spacecraft observations have confirmed this notion, and revealed past or present endogenic activity even on bodies where this was not previously expected.The study of endogenic processes and their resulting landforms and landscapes puts important constraints on the internal evolution and the surface history of a geologic body
Interiors and atmospheres
No full textThe formation and evolution of the crust, magnetic field and atmosphere of a terrestrial planets are fundamental, global-scale processes that are intimately related to the thermal evolution, structure, and composition of the deep interior. In this chapter we introduce the present understanding of the physical processes that connect these different aspects of planetary evolution and lead to the diversity of planetary surfaces and histories that we observe
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
Animated Points: Storing and Retrieving Time-Dependent Information
No full textIn geosciences map animations help to explore, analyze and validate complex settings and to display – and ultimately understand – higher dimensions of information by combining attribute information from multiple sources. Despite the omnipresence of geographic information system technology (GIST), standard information systems (IS) are not designed to store temporal information on the same implementation level as spatial information is stored. However, it is possible to model temporal information as another object attribute despite several limitations. The objective of this paper is to develop a structural model for storing and accessing spatial data primitives that are connected to their naturally temporal information for the purpose of creating map animations. We here summarize the nature of (carto-) graphic variables and discuss their potential use for map animation in general and for animated point symbols in particular. Scenarios of simple and complex feature animations complement this discussion. Our results lead to a simple data model in which temporal information can be stored on an attribute level, accessed using standard relational queries and animated as map features
