Die archäologische Erforschung der Silvretta hat zur Entdeckung zahlreicher bisher unbekannter Fundstellen geführt, deren Untersuchung tiefe Einblicke in die Geschichte dieser Region erlaubt. Doch woher wissen Archäologen, wo sie etwas finden? Die Suche und Identifizierung von archäologischen Fundstellen, die sogenannte Prospektion, ist ein wichtiger Aspekt der Arbeiten in der Silvretta. Neben traditionellen Methoden kommen dabei auch hochmoderne Verfahren wie unbemannte Fluggeräte oder die teilautomatisierte Auswertung von Satellitenbildern zum Einsatz.
As part of a long-term project to investigate the cultural history of the Nasca region in southern Peru, the famous
Nasca lines, or geoglyphs, have been documented since 1997 in a joint effort by archaeologists and geomatic engineers. The
project aims on the one hand at a new interpretation of the geoglyphs based on solid field data. On the other hand, it is thought
of as a contribution to the preservation of the geoglyphs. Prior to the start of the project, the geoglyphs had never been
adequately recorded. In a new approach that combined aerial photogrammetry with archaeological fieldwork, we thoroughly
documented more than 1 500 geoglyphs in the vicinity of Palpa. While different aspects of this work have been described in
previous reports, this paper offers an overview of the technical procedures from data acquisition to processing, modeling, and
The goal of this paper is to examine regularities and differences in the application of the three terms assigned expatriate (AE), self-initiated expatriate (SIE) and migrant as the criteria for demarcation are unclear (Al Ariss, 2010; Baruch, Dickmann, Altman, &Bournois, 2010). This research adopts a qualitative approach, using the tool of qualitative content analysis (Mayring, 2010). The data base includes 244 definitions from 10 sociological, psychological and business journals. Results indicate that migrant is the umbrella term for AE and SIE. Therefore a SIE is a migrant who executes his dependent work abroad. In contrast to AEs, decision of employment is made by the host country organization and the first formalized action (i. e. job application) is undertaken by the individual.
Evidence on age-related differentiation in the structure of cognitive abilities in childhood and adolescence is still inconclusive. Previous studies often focused on the interrelations or the g-saturation of broad ability constructs, neglecting abilities on lower strata. In contrast, we investigated differentiation in the internal structure of fluid intelligence/gf (with verbal, numeric, and figural reasoning) and crystallized intelligence/gc (with knowledge in the natural sciences, humanities, and social studies). To better understand the development of reasoning and knowledge during secondary education, we analyzed data from 11,756 students attending Grades 5 to 12. Changes in both the mean structure and the covariance structure were estimated with locally-weighted structural equation models that allow handling age as a continuous context variable. To substantiate a potential influence of school tracking (i.e., different learning environments), analyses were additionally conducted separated by school track (academic vs. nonacademic). Mean changes in gf and gc were approximately linear in the total sample, with a steeper slope for the latter. There was little indication of age-related differentiation for the different reasoning facets and knowledge domains. The results suggest that the relatively homogeneous scholastic learning environment in secondary education prevents the development of more pronounced ability or knowledge profiles.
