Dieser Beitrag beschäftigt sich mit verschiedenen Ansätzen der Konstruktion von Grundwortschatzbeständen für den Bereich Deutsch als Fremdsprache. Am Beispiel des kommunikativ-pragmatisch erstellten Wortschatzes, der in Profile Deutsch erfasst ist, und zwei frequenzorientierten Listen, der DeReWo Wortliste und der Herder/BYU Häufigkeitsliste, werden anhand einer empirischen Gegenüberstellung Stärken und Schwächen der verschiedenen Ansätze herausgestellt. Resümierend werden in diesem Beitrag Desiderate sowie mögliche Lösungsansätze zur validen und empirisch abgesicherten Grundwortschatzbestimmung zur Diskussion gestellt.
It is common knowledge that plants have been the world-wide most important source of medicines and that they still play this role in developing countries. However, up to now, complete lists of medicinal and aromatic plants (MAP) exist for comparatively few countries. A review of all lists know to the authors reveals the following results: A total of 20.7 % of the plant species analyzed by either publications or own research are or were used as MAP. However, regarding single countries, the differences are considerably high. Absolutely leading the list are China (36.2 %), Burkina Faso (35.2 %) and the Korean Republic (34.5 %). Also ahead of other countries or regions are the North of Benin (32.8 %) and the entire Pakistan (30.3 %). Still above average rank Great Britain (26.7 %) and Nepal (23.3 %), while the figures for Bul¬garia (21.0 %), Germany (20.2 %) and France (19.4 %) almost represent the average. Jordan (17.3 %), Vietnam (17.1 %), Sri Lanka (16.6 %), India (16.1 %) and Thailand (15.5 %) rank slightly beneath. Clearly below the average are the percentages of MAP for Hungary (12.2 %) and the USA (11.8 %). The average numbers of MAP in the Philippines (9.5 %) and Malaysia (7.7 %) fall far behind. Calculated on a worldwide scale, every fifth plant can be regarded as MAP. This number matches that from Bulgaria, France and Germany. In northern Benin, Burkina Faso, Korea, China and Pakistan, however, every third plant is or was used as MAP, whereas in Hungary and the USA only every eighth plant can be regarded as MAP. This number drops even further for the Philippines ore Malaysia where only every tenth or thirteenth plant can be attributed to medicinal or aromatic use. These differences might be due to various factors. A geographical component of the results is obvious: in most cases geographically close countries show similar percentages. A correlation between the total number of species and the fraction of those used as MAP cannot be confirmed. The countries with percentage of MAP > 30 % in common show that they belong either entirely (Burkina Faso, Benin) or at least in their rural areas to the poorest countries of the world so that it is (was) impossible for the majority of the people to buy "modern" MAP. In those countries the number of traditional healers outnumbers largely the number of modern doctors. Therefore, the tradition of folk medicine was maintained until today. Additionally, China, Korea and partially Pakistan have a very old and well documented tradition of folk medicine. Due to this documentation even in areas where today "modern MAP" are used, the knowledge was not lost. In neighboring countries or regions, which differ with respect to a more arid or a more humid climate, for the arid country (region) more MAPs are reported than for the humid one. The potential reasons for this phenomenon are discussed in the paper. For many countries the percentage given for MAP in literature is too low. But even these low values represent a striking argument for the importance of a world-wide conservation of biodiversity.

Background: Only few studies deal with the workload of physical therapists and the health consequences, although this occupational group is quite important for the health care system in many industrialized countries (e.g. ca. 136 000 people are currently employed as physical therapists in Germany). Therefore, the current state of knowledge of work-related diseases and disorders of physical therapists is insufficient. The aim of the "Physical Therapist Cohort" (PTC) study is to analyze the association between work-related exposures and diseases among physical therapists in Germany. This article describes the protocol of the baseline assessment of the PTC study.
Methods/Design: A cross-sectional study will be conducted as baseline assessment and will include a representative random sample of approximately 300 physical therapists employed in Germany (exposure group), and a population-based comparison group (n = 300). The comparison group will comprise a sample of working aged (18–65 years) inhabitants of a German city. Variables of interest will be assessed using a questionnaire manual including questions regarding musculoskeletal, dermal, and infectious diseases and disorders as well as psychosocial exposures, diseases and disorders. In addition to subjective measures, a clinical examination will be used to objectify the questionnaire-based results (n = 50).
Discussion: The study, which includes extensive data collection, provides a unique opportunity to study the prospective association of work-related exposures and associated complaints of physical therapists. Baseline results will give first clues with regard to whether and how prevalent main exposures of physiotherapeutic work and typical work areas of physical therapists are associated with the development of work-related diseases. Thereby, this baseline assessment provides the basis for further investigations to examine causal relationships in accordance with a longitudinal design.
Education is an important tool for the development of human potential. Organizations and individuals interested in development consider knowledge, skills and attitudes, obtained through formal, non-formal and incidental learning, as invaluable assets. Therefore, it is necessary to reflect on fundamental elements that shape the process through which education is attained: How do people learn, and what are the conditions that facilitate effective learning? Answers to these questions demonstrate that no education can be politically neutral, because there is no value-free education. The traditional or indigenous education systems in Nigeria, which covered (and still cover) physical training, development of character, respect for elders and peers, development of intellectual skills, specific vocational trainings, developing a sense of belonging and participation in community affairs, and understanding, appreciating and promoting the cultural heritage of the community were, and are, not value-free. In other words, the goals and purpose of education, the content, the entire process and the procedures chosen for evaluation in education are all value-laden. This book attempts to show that the teaching-learning process in higher education, and religion, taught and learned through non-formal and informal education (or the hidden curriculum), and other socialization processes within and outside the formal school system, all interface to determine the persons that women become. This education enhances or limits women's capabilities, whether in the civic-political sphere or in their attempts to resist violence. Hence, education and religion have ways of empowering or disempowering women.
Bislang war in deutschen Städten das Wohnen im Eigentum – entweder im Eigenheim oder in der Eigentumswohnung – die Ausnahme. Insbesondere in Großstädten dominierte das Wohnen zur Miete. Gegenwärtig ändert sich dies: Großstädte wie Frankfurt, Berlin, Hamburg, Köln und München sind gegenwärtig geprägt von einer Kauflust privater und institutioneller Investoren. Zugleich hat in vielen Städten ein Ausverkauf und/oder Vermarktlichung des öffentlichen Wohnungsbestandes stattgefunden. Dies hat dazu beigetragen, dass die Preise sehr stark angestiegen sind. In dem Beitrag wird die aktuelle Entwicklung auf städtischen Wohnungsmärkten in Deutschland als Folge einer Finanzialisierung von Immobilien sowie einer Responsibilisierung im Bereich der Wohnversorgung analysiert. Es wird gefragt, welche Folgen dies in Städten hat.
Diese Arbeit entstand im Rahmen eines größeren Forschungsprojektes zum Thema Bewältigung von Lebensenttäuschungen, initiiert von Prof. Dr. Siegfried Preiser am Institut für Psychologie der Universität Frankfurt am Main. In diesem Kontext wurde die vorliegende Studie entwickelt.
Ausgehend von interpersonalem Engagement wurden mögliche Verknüpfungen von Einflussfaktoren im Umgang mit unterschiedlichen kritischen Lebenssituationen und der sich daraus ergebenden Konsequenzen auf psychische und physische Gesundheit, d.h. persönliches Wohlbefinden untersucht. Das Konstrukt Wohlbefinden wurde in dieser Studie als eine latente Variable gebildet, die sich aus einer Konstellation von bereichsspezifischen und allgemeinen Lebenszufriedenheitsfaktoren, dem seelischen Gesundheitsempfinden und – mit negativem Gewicht - dem aktuellen Belastungsempfinden zusammensetzt.
Außer der Erfassung der Partizipation an sozialen Gemeinschaften bzw. des sozialen Engagements wurden intrapsychische, motivationale, biographische und soziale Faktoren erfasst sowie religiöse Aspekte einbezogen. Zielgruppen der Untersuchung waren Gruppierungen vorwiegend aus dem Selbsthilfebereich.
Zur Beachtung der Zeitperspektive war die Befragung als Längsschnittstudie in Form einer Zweifachmessung konzipiert.
Erhoben und untersucht wurden im einzelnen Belastungs-, Persönlichkeits-, Gesundheits- und Zufriedenheitsfaktoren, des Weiteren die Aspekte des sozialen Kontextes mit Differenzierung der Ebenen von sozialer Unterstützung sowie religiöse Aspekte als angenommene Einflussfaktoren auf Lebenszufriedenheit und persönliches Wohlbefinden.
Zusammenfassend hatten die Persönlichkeitsfaktoren Flexibilität und Selbstwirksamkeit den größten positiven Einfluss auf Wohlbefinden. Bzgl. des sozialen Engagements zeigte sich dagegen kein signifikanter Einfluss.
Neben den Variablen Flexibilität und Selbstwirksamkeit stellte sich die wahrgenommene Unterstützung als bedeutsamster Einflussfaktor auf das Wohlbefinden heraus.
Religiöse Vorstellungen konnten nach ihrer persönlichen positiven oder negativen Grundhaltung gegenüber Gott bzw. einer höheren Wirklichkeit differenziert werden. Eine positive religiöse Grundhaltung ist geprägt von der Vorstellung eines schützenden, fürsorglichen und hilfreichen Gottes. Ein negatives Gottesbild beinhaltet die Vorstellung eines bedrohlichen und strafenden Gottes. Nur für diese Betrachtungsweise konnten eindeutige - und zwar negative - Einflüsse auf das Wohlbefinden ermittelt werden

Reproducing the characteristics and the functional responses of the blood–brain barrier (BBB) in vitro represents an important task for the research community, and would be a critical biotechnological breakthrough. Pharmaceutical and biotechnology industries provide strong demand for inexpensive and easy-to-handle in vitro BBB models to screen novel drug candidates. Recently, it was shown that canonical Wnt signaling is responsible for the induction of the BBB properties in the neonatal brain microvasculature in vivo. In the present study, following on from earlier observations, we have developed a novel model of the BBB in vitro that may be suitable for large scale screening assays. This model is based on immortalized endothelial cell lines derived from murine and human brain, with no need for co-culture with astrocytes. To maintain the BBB endothelial cell properties, the cell lines are cultured in the presence of Wnt3a or drugs that stabilize β-catenin, or they are infected with a transcriptionally active form of β-catenin. Upon these treatments, the cell lines maintain expression of BBB-specific markers, which results in elevated transendothelial electrical resistance and reduced cell permeability. Importantly, these properties are retained for several passages in culture, and they can be reproduced and maintained in different laboratories over time. We conclude that the brain-derived endothelial cell lines that we have investigated gain their specialized characteristics upon activation of the canonical Wnt pathway. This model may be thus suitable to test the BBB permeability to chemicals or large molecular weight proteins, transmigration of inflammatory cells, treatments with cytokines, and genetic manipulation.
