eLEARNING

eLearning through its flexibility and facility of access is seen as a major enabler of lifelong learning (LLL), as a catalyst of change and a chance for small and medium-sized enterprises (SMEs) to improve their business and to integrate into European market. But so far eLearning in the context of vocational educational training mainly has been adopted by large enterprises, while only little activity can be observed in SMEs. The question arises what the chances and challenges for SMEs are and what are the experience with its usage. In this paper after a presentation of key issues in eLearning chances and challenges of eLearning for SMEs are discussed and experiences are exemplified by three EU-funded eLearning projects. The focus lies on the ongoing project ARIEL - Analysing and Reporting the Implementation of Electronic Learning in Europe – coordinated by the Institut Arbeit und Technik (IAT).

Leben für die Sache. Vera Figner, Vera Zasulič und das radikale Milieu im späten Zarenreich

In der zweiten Hälfte des 19. Jahrhunderts treten in Russland vermehrt Frauen und Männer in die Öffentlichkeit, die durch radikale Veränderungen einen „neuen Menschen“ und mit ihm eine neue Gesellschaft schaffen wollen. Vera Figner und Vera Zasulič, die beiden Protagonistinnen der vorliegenden Untersuchung, sind herausragende Vertreterinnen der radikalen Bewegung im ausgehenden Zarenreich. Während Vera Zasulič mit ihrem Attentat auf den St. Petersburger Stadtkommandanten Fëdor Trepov 1878 am Beginn der ersten terroristischen Welle in Russland steht, ist Vera Figner bei ihrer Verhaftung 1883 das letzte führende Mitglied der Terrororganisation Narodnaja Volja (Volkswille), die am 1./13. März 1881 einen tödlichen Anschlag auf Zar Aleksandr II. verübt. Die beiden Frauen verbindet zwar kein engerer persönlicher Kontakt, dafür aber die Zugehörigkeit zum selben Milieu. Beeinflusst von der progressiven Debatte in der Intelligencija der 1860er Jahre entschlossen sie sich bereits in ihrer Jugend, sich von traditionellen Standes- und Geschlechterrollen zu lösen, ihr Schicksal „in die eigenen Hände zu nehmen“ und sich einer „Sache“ zu verschreiben. Zusammen mit anderen Radikalen gerieten sie dadurch in einen immer heftigeren Konflikt mit der autokratischen Staatsmacht, der sich schließlich zu einem Kampf mit terroristischen Mitteln steigerte. Stephan Rindlisbacher nutzt die Biographien dieser beiden radikalen Frauen als „Scheinwerfer“, um das radikale Milieu mit seinen Merkmalen, Funktionsmechanismen und Handlungsspielräumen auszuleuchten. Aus zwei voneinander unabhängigen aber vergleichbaren Blickwinkeln zeichnet er ein eindrucksvolles Bild nicht nur der radikalen Netzwerkstrukturen, Symbole, Praktiken und Identitätsnarrativen, sondern auch der beteiligten Menschen mit ihren Wünschen, Hoffnungen und Ängsten.

Deleterious effects of roving on learned tasks

In typical perceptual learning experiments, one stimulus type (e.g., a bisection stimulus offset either to the left or right) is presented per trial. In roving, two different stimulus types (e.g., a 30′ and a 20′ wide bisection stimulus) are randomly interleaved from trial to trial. Roving can impair both perceptual learning and task sensitivity. Here, we investigate the relationship between the two. Using a bisection task, we found no effect of roving before training. We next trained subjects and they improved. A roving condition applied after training impaired sensitivity.

National youth team football players between the conflicting priorities of sports success and vocational training

In view of the risks involved in relying on a professional career in football as a way of making a future living, most players on Swiss National Youth Football Teams pursue some form of vocational training at the same time. This paper investigates the question under what conditions a successful football career is possible when faced with such a dual burden. In order to examine the development process as holistically as possible, a person-oriented approach was chosen. 159 former Swiss National Youth Team players were retrospectively interviewed about their careers, and the data were analysed using the LICUR method (Bergman, Magnusson, & El-Khouri, 2003). This involves identifying certain patterns in the relevant variables of sports career, vocational career and family support, and then comparing these with the performance at the age of peak performance. Through this, it was possible to identify promising patterns of development. It turns out that the critical transition, at the age of about 15–16 years, is characterised overall by stability. The most successful patterns display above-average family support accompanied by above-average professional talent promotion in the clubs. In this constellation, the football players who are later successful pursue vocational training courses leading to low levels of educational qualification.

"Mir hei e Verein": Eine Studie über Vereine, Sozialkapital und Wohlstand im Kanton Bern

In diesem Beitrag untersuchen wir den Zusammenhang zwischen dem Sozialkapitalbestand der 382 Gemeinden des Kantons Bern und deren wirtschaftlichen Prosperität. Als Indikator für das Sozialkapital verwenden wir die Anzahl an Vereinen. Nach unseren Recherchen gibt es im Kanton Bern insgesamt 10 130 Vereine. Die statistischen Analysen zeigen, dass selbst unter Kontrolle von weiteren Merkmalen Gemeinden mit vielen Vereinen über ein höheres Einkommen pro Einwohner verfügen. In einer Unterstichprobe von 100 Gemeinden wurde zusätzlich eine schriftliche Befragung von 2 577 Vereinen durchgeführt. Die Resultate ergeben, dass für den Wohlstand der Gemeinden insbesondere die Anzahl an aktiven Mitgliedern ausschlaggebend ist. Vereine mit Fokussierung auf das Gemeinwohl (Putnam-Vereine) haben zudem eine grössere Bedeutung für den Wohlstand als Vereine, die eher Partikularinteressen vertreten (Olson-Vereine). Insgesamt bestätigen die Ergebnisse die Sozialkapitalthese.

Hypereosinophiliesyndrome

In den vergangenen Jahren wurden zahlreiche neue Erkenntnisse zur Biologie eosinophiler Granulozyten, ihrer Rolle für die Gesundheit und bei Krankheiten gewonnen. Differenzierte Kenntnisse zur Pathogenese, neue diagnostische Methoden und Therapeutika haben das Verständnis zur Hypereosinophilie und damit assoziierten Erkrankungen und Syndromen fundamental geändert. In dieser Übersichtsarbeit diskutieren wir die gegenwärtige Klassifikation der Hypereosinophiliesyndrome und neue Therapieansätze.

Into the abyss of Lake Geneva: the elemo interdisciplinary field investigation using the MIR submersibles

In summer 2011, the two Russian MIR sub- mersibles were brought to Switzerland to perform deep water dives in Lake Geneva. Research teams from several environmental science institutes, both national and inter- national, participated in this interdisciplinary effort to investigate the deeper parts of Lake Geneva. Using the MIRs allowed the scientists to see and precisely select the sites where they could extract specific sediment cores and carry out detailed in situ measurements at the sediment– water boundary. One focus site was the surrounding of the outlet of the wastewater treatment plant of the City of Lausanne, which discharges into the Vidy Bay. The investigations concentrated on the pollution of the local sediments, pollution-related ecotoxicological risks, micro- bial activity and spreading and removal of the effluents from the bay to the open waters of the lake. The other focus site was the Rhoˆne River delta and its subaquatic canyons, which formed as a result of the long-term interplay of the deposition of river-borne sediments and flood-triggered canyon erosion events.

Eosinophils

In 1846, T. Wharton-Jones described a coarsely granular stage in the development of granulocytic cells in animal and human blood. Shortly thereafter, Max Schultze redefined the coarsely granular cells as a type distinct from finely granular cells, rather than just a developmental stage. It was, however, not until 1879, when Paul Ehrlich introduced a method to distinguish granular cells by the staining properties of their granules, that a classification became possible. An intensive staining for eosin, among other aniline dyes, was eponymous for the coarsely granular cell type, which thereupon became referred to as eosinophil granulocyte. Eosinophilia had already been described in many diseases by the late 19th century. The role of these cells, however, today remains a matter of continuing speculation and investigation. Many functions have been attributed to the eosinophil over the years, often linked to increasing knowledge about the granular and cytoplasmatic contents. A better understanding of the regulatory mechanisms of eosinopoiesis has led to the development of knock-out mice strains as well as therapeutic strategies for reducing the eosinophil load in patients. The effect of these therapeutics and the characterization of the knock-out phenotypes have led to a great increase in the knowledge of the role of the eosinophil in disease. Today we think of the eosinophil as a multifunctional cell involved in host defense, tissue damage and remodeling, as well as immunomodulation.

Atlas-based Segmentation of Tumor-bearing Brain Images

In diagnostic neuroradiology as well as in radiation oncology and neurosurgery, there is an increasing demand for accurate segmentation of tumor-bearing brain images. Atlas-based segmentation is an appealing automatic technique thanks to its robustness and versatility. However, atlas-based segmentation of tumor-bearing brain images is challenging due to the confounding effects of the tumor in the patient image. In this article, we provide a brief background on brain tumor imaging and introduce the clinical perspective, before we categorize and review the state of the art in the current literature on atlas-based segmentation for tumor-bearing brain images. We also present selected methods and results from our own research in more detail. Finally, we conclude with a short summary and look at new developments in the field, including requirements for future routine clinical use.

The phenomenology of lucid dreaming: An online survey.

In lucid dreams the dreamer is aware that he or she is dreaming. Although such dreams are not that uncommon, many aspects of lucid dream phenomenology are still unclear. An online survey was conducted to gather data about lucid dream origination, duration, active or passive participation in the dream, planned actions for lucid dreams, and other phenomenological aspects. Among the 684 respondents who filled out the questionnaire, there were 571 lucid dreamers (83.5%). According to their reports, lucid dreams most often originate spontaneously in adolescence. The average lucid dream duration is about 14 minutes. Lucid dreamers are likely to be active in their lucid dreams and plan to accomplish different actions (e.g., flying, talking with dream characters, or having sex), yet they are not always able to remember or successfully execute their intentions (most often because of awakening or hindrances in the dream environment). The frequency of lucid dream experience was the strongest predictor of lucid dream phenomenology, but some differences were also observed in relation to age, gender, or whether the person is a natural or self-trained lucid dreamer. The findings are discussed in light of lucid dream research, and suggestions for future studies are provided.

Temperature reconstruction from 10 to 120 kyr b2k from the NGRIP ice core

In order to reconstruct the temperature of the North Greenland Ice Core Project (NGRIP) site, new measurements of δ15N have been performed covering the time period from the beginning of the Holocene to Dansgaard–Oeschger (DO) event 8. Together with previously measured and mostly published δ15N data, we present for the first time a NGRIP temperature reconstruction for the whole last glacial period from 10 to 120 kyr b2k (thousand years before 2000 AD) including every DO event based on δ15N isotope measurements combined with a firn densification and heat diffusion model. The detected temperature rises at the onset of DO events range from 5 °C (DO 25) up to 16.5 °C (DO 11) with an uncertainty of ±3 °C. To bring measured and modelled data into agreement, we had to reduce the accumulation rate given by the NGRIP ss09sea06bm timescale in some periods by 30 to 35%, especially during the last glacial maximum. A comparison between reconstructed temperature and δ18Oice data confirms that the isotopic composition of the stadial was strongly influenced by seasonality. We evidence an anticorrelation between the variations of the δ18Oice sensitivity to temperature (referred to as α) and obliquity in agreement with a simple Rayleigh distillation model. Finally, we suggest that α might be influenced by the Northern Hemisphere ice sheet volume.

210Pb dating of the Miaoergou ice core from the eastern Tien Shan, China

In 2005, two ice cores with lengths of 58.7 and 57.6 m respectively to bedrock were recovered from the Miaoergou flat-topped glacier (43 degrees 03 ' 19 '' N, 94 degrees 19 ' 21 '' E; 4512 m a.s.l.), eastern Tien Shan. Pb-210 dating of one of the ice cores (57.6 m) was performed, and an age of AD 1851 +/- 6 at a depth of 35.2 m w.e. was determined. For the period AD 1851-2005, a mean annual net accumulation of 229 +/- 7 mm w.e. a(-1) was calculated. At the nearby oasis city of Hami (similar to 80 km from the Miaoergou flat-topped glacier) the annual precipitation rate is 38 mm w.e. a(-1), hence glacial meltwater is a major water supply for local residents. The surface activity concentration of Pb-210(ex) was found to be similar to 400 mBq kg(-1), which is higher than observed at other continental sites such as Belukha, Russia, and Tsambagarav, Mongolia, which have surface activity concentrations of 280 mBq kg(-1). The Pb-210 dating agrees well with the chronological sequence deduced from the annual-layer counting resulting from the seasonalities of delta O-18 and trace metals for the period AD 1953-2005, and beta-activity horizons resulting from atmospheric nuclear testing during the period AD 1962-63. We conclude that Pb-210 analysis is a suitable method for obtaining a continuous dating of the Miaoergou ice core for similar to 160 years, which can also be applied to other ice cores recovered from the mountains of western China.

Plant diversity effects on the water balance of an experimental grassland

In the literature, contrasting effects of plant species richness on the soil water balance are reported. Our objective was to assess the effects of plant species and functional richness and functional identity on soil water contents and water fluxes in the experimental grassland of the Jena Experiment. The Jena Experiment comprises 86 plots on which plant species richness (0, 1, 2, 4, 8, 16, and 60) and functional group composition (zero to four functional groups: legumes, grasses, tall herbs, and small herbs) were manipulated in a factorial design. We recorded meteorological data and soil water contents of the 0·0–0·3 and 0·3–0·7 m soil layers and calculated actual evapotranspiration (ETa), downward flux (DF), and capillary rise with a soil water balance model for the period 2003–2007. Missing water contents were estimated with a Bayesian hierarchical model. Species richness decreased water contents in subsoil during wet soil conditions. Presence of tall herbs increased soil water contents in topsoil during dry conditions and decreased soil water contents in subsoil during wet conditions. Presence of grasses generally decreased water contents in topsoil, particularly during dry phases; increased ETa and decreased DF from topsoil; and decreased ETa from subsoil. Presence of legumes, in contrast, decreased ETa and increased DF from topsoil and increased ETa from subsoil. Species richness probably resulted in complementary water use. Specific functional groups likely affected the water balance via specific root traits (e.g. shallow dense roots of grasses and deep taproots of tall herbs) or specific shading intensity caused by functional group effects on vegetation cover.

Vom Kommentieren

In Germanistic philological editing, theoretical discussion on the commentary assumes traditionally a secondary role compared to the manifold contributions on other subjects of textual philology. Already in 1924, Georg Witkowski admonished to enhance scholarly debates on the commentary, and the claim has since been repeated several times. This paper reflects current discussions in the context of contemporary annotation practice, wishing to trigger new considerations of how the intellectual genesis of text and the contexts of literary works can be adequately illustrated in the commentaries.
