Modellierung und kartographische Visualisierung von Geodaten mit XML-basierten Sprachen     

Brigitte Mathiak  Andreas Kupfer  Karl Neumann 《Informatik - Forschung und Entwicklung》2005,6(2):24-32

Mit den XML-basierten Sprachen GML, XSLT und SVG lassen sich Geodaten nicht nur anwendungsorientiert modellieren, sondern auch karten?hnlich visualisieren. In dieser Fallstudie zeigen wir das, indem wir realistische Geodatenbest?nde der Landesvermessungs?mter zun?chst mit der Geography Markup Language (GML) nachmodellieren. So mit GML strukturierte Daten werden dann mit der Extensible Stylesheet Language for Transformation (XSLT) auf Elemente der Sprache Scalable Vector Graphics (SVG) abgebildet. Dabei wird der Prozess der kartografischen Visualisierung durch XSLT-Konstrukte modelliert und auch gleichzeitig implementiert. Als Ergebnis erhalten wir Grafiken, die den entsprechenden Karten der Landes?mter zumindest nicht un?hnlich sind.  相似文献   

How to Support and to Bring About the Shift from Teaching to Learning through Academic Staff Development Programmes: Examples and Perspectives     

Brigitte Berendt 《Higher Education in Europe》1998,23(3):317-329

This article opens with a survey of developments indicative of the shift from teaching to learning. It then surveys the situation in the 1990s and answers questions relevant to the encouragement of effective teaching. It continues by dealing with the question of how to encourage the shift from teaching to learning by means of staff development programmes for higher education teaching personnel. The author presents successful concepts that she developed in the context of a pilot study undertaken between 1975 and 1979. She applied them within workshops not only in her own university but in numerous eastern European and African universities and at the University of the Philippines in 1997 and 1998. A final section summarizes some perspectives for the UNESCO World Conference on Higher Education: Higher Education in the Twenty‐First Century‐‐"Vision and Action' that was held in Paris from 5 to 9 October 1998.  相似文献   

The use of migration-related competencies in continuing education: individual strategies,social and institutional conditions     

Ariane Sadjed  Brigitte Kukovetz 《Studies in Continuing Education》2015,37(3):286-301

Focusing especially on biographical competencies that are gained through the experience of migration and socialisation in a certain country or cultural context, this article analyses how professionals define and deploy these ‘migration-related competencies’ when it comes to employment in the field of adult education in Austria. By means of selected example cases individual strategies are discussed vis-à-vis institutional frameworks of adult education and processes of exclusion towards migrants in general. Considering questions of representation and othering, the circumstances under which the utilisation of migration-related competencies is experienced as beneficial or problematic are examined. Furthermore, educational institutions of the majority society display different modes of recognising and acknowledging migration-related competencies. In a context, in which the official acknowledgement of these practices by institutions and transparent policies towards diversity orientation are lacking, the possession and demonstration of migration-related competencies has shown to be a highly ambivalent and individualised process.  相似文献   

Phospholipid—polymer amphiphile hybrid assemblies and their interaction with macrophages     

Karthiga Panneerselvam  Martin E. Lynge  Camilla Frich Riber  Sofia Mena-Hernando  Anton A. A. Smith  Kenneth N. Goldie  Alexander N. Zelikin  Brigitte St?dler 《Biomicrofluidics》2015,9(5)

Recently, the combination of lipids and block copolymers has become an alternative to liposomes and polymersomes as nano-sized drug carriers. We synthesize novel block copolymers consisting of poly(cholesteryl acrylate) as the hydrophobic core and poly(N-isopropylacrylamide) (PNIPAAm) as the hydrophilic extensions. Their successful phospholipid-assisted assembly into vesicles is demonstrated using the evaporation-hydration method. The preserved thermo-responsive property of the lipid-polymer hybrids is shown by a temperature dependent adsorption behaviour of the vesicles to poly(l lysine) coated surfaces. As expected, the vesicle adsorption is found to be higher at elevated temperatures. The cellular uptake efficiency of hybrids is assessed using macrophages with applied shear stress. The amount of adhering macrophages is affected by the time and level of applied shear stress. Further, it is found that shorter PNIPAAm extensions lead to higher uptake of the assemblies by the macrophages with applied shear stress. No inherent cytotoxicity is observed at the tested conditions. Taken together, this first example of responsive lipid-polymer hybrids, and their positive biological evaluation makes them promising nano-sized drug carrier candidates.  相似文献   

The Role of Family Characteristics for Students’ Academic Outcomes: A Person‐Centered Approach          下载免费PDF全文

Using data from 1,571 ninth‐grade students (M_age = 14.62) from 82 academic track schools in Germany and their predominantly Caucasian middle‐class parents, configurations of different family characteristics reported by parents were investigated. Latent profile analyses considering academic involvement, family interest, parents’ self‐concept, child's need for support, and parents’ time and energy identified average, indifferent, motivated and engaged, motivated and disengaged, and involved families. Cross‐sectional and longitudinal associations with students’ motivational (self‐concept, effort, and interest) and achievement outcomes (achievement test and grades) in math were analyzed. Students from families classified as motivated and disengaged showed higher initial levels motivation and achievement. Over 5 months, these students also showed an increase in self‐concept and higher achievement than students from other family types.  相似文献   

Academic careers for graduate students: a strong attractor in a changed environment     

Brigitte Gemme  Yves Gingras 《Higher Education》2012,63(6):667-683

Professorship has traditionally been the single most valued career path for graduates of PhD programs. Policies now encourage graduate students to directly or indirectly engage with non-academic organizations to encourage the next generation of researchers to explore alternative careers, including opportunities in industry and government. In this article, we use data from a survey of Quebec science and engineering graduate students to examine the impact of their participation in university-industry-government research partnerships on their professional preferences. We assess the degree to which exposure to non-academic realities through different training arrangements relates to career preferences, and how these preferences evolve over time. We show that the proportion of students who did not change their preferred career path over time is high, indicating that by the time students engage in a research-training program they already, for the most part, know what career they want to pursue. However, and although students with close ties to non-academic partners may initially be more interested in non-academic career paths, over time all categories of students become more attracted to academic careers. We conclude that faculty positions continue to dominate the professional dreams of fledgling researchers, a power of attraction that increases as students advance in their program, even when it involves industrial contacts.  相似文献   

Evaluation of a numeracy intervention program focusing on basic numerical knowledge and conceptual knowledge: a pilot study     

Kaufmann L  Handl P  Thöny B 《Journal of learning disabilities》2003,36(6):564-573

The preliminary results of this study suggested that children with developmental dyscalculia benefit from a numeracy intervention program that focuses on basic numerical knowledge and conceptual knowledge. All children in the experimental group showed considerable and partly significant performance increases on all calculation components. Six children with developmental dyscalculia were trained individually and in small-group settings for a relatively short duration (one school semester). We argue that the positive intervention effects to a large extent are attributable to the explicit teaching of numerical domains that often have been found to be neglected in school mathematics.  相似文献
