4010 Feuchte Heidegebiete des nordatlantischen Raumes mit Erica tetralix
Beschreibung und wertbestimmende Faktoren des Lebensraumtypes 4010 Feuchte Heidegebiete des nordatlantischen Raumes mit Erica tetralix nach Anhang I der Fauna-Flora-Habitatrichtlinie im Land Sachsen-Anhalt. Zum Lebensraumtyp zählen feuchte Zwergstrauchheiden und Heidevermoorungen im nordatlantischen und mitteleuropäischen Raum, die durch Dominanz der Glockenheide (Erica tetralix) bestimmt werden
Smart Media Navigator: Visualizing recommendations based on linked data
The growing content in online media libraries results in an increasing challenge for editors to curate their information and make it visible to their users. As a result, the users are confronted with the great amount of content, unable to find the information they are really interested in. The Smart Media Navigator (SMN) aims to analyze a platform’s entire content, enrich it with Linked Data content, and present it to the user in an innovative user interface with the help of semantic web technologies. The SMN enables the user to dynamically explore and navigate media library content
Semantic Annotation and Information Visualization for Blogposts with refer
The growing amount of documents in archives and blogs results in an increasing challenge for curators and authors to tag, present, and recommend their content to the user. refer comprises a set of powerful tools focusing on Named Entity Linking (NEL) which help authors and curators to semi-automatically analyze a platform’s textual content and semantically annotate it based on Linked Open Data. In refer automated NEL is complemented by manual semantic annotation supported by sophisticated autosuggestion of candidate entities, implemented as publicly available Wordpress plugin. In addition, refer visualizes the semantically enriched documents in a novel navigation interface for improved exploration of the entire content across the platform. The efficiency of the presented approach is supported by a qualitative evaluation of the user interfaces
How Substitutable Are Workers? Evidence from Worker Deaths
To assess the substitutability between workers within a firm, and between incumbent workers and outsiders, we estimate how exogenous worker exits affect a firm’s demand
for incumbent workers and new hires. Using matched employer-employee data from Germany, we analyze the effects of 34,000 unexpected worker deaths and show that these worker exits on average raise the remaining workers’ wages and retention probabilities for a period of several years. The average effect masks substantial heterogeneity: Coworkers in the same occupation as the deceased see positive wage effects; coworkers in other occupations instead experience wage decreases when a high-skilled worker or manager dies. Finally, when the external labor market in the deceased’s occupation is thin, incumbents’ wages respond more and external hiring responds less to a worker death. Taken together, our findings imply that incumbent workers are closer substitutes to one another compared to outsiders, that high-skilled workers and managers are complements to coworkers in other occupations, and that thin external markets for skills lead to higher firm-specificity of human capital and lower replaceability of incumbents
Evaluation of a test module to measure relevant components of ball release height in jump throws in team handball
This study aims to analyse different performance factors of jump throws in team handball. These factors cover anthropometric prerequisites (body height and Standing Reach Height – SRH), general jump abilities (Jumping Reach Height during a countermovement jump – JRH), aspects of the jump technique (Ball Height during a handball specific Jump – BHJ) as well as the throwing technique (Ball release Height during a jump Throw – BHT). 36 male team handball players from three different senior leagues were analysed to quantify the extent to which these components vary with competitive levels and playing positions. Additionally, 30 subjects (highest national junior league) were recruited to examine the appropriateness of the components with respect to predicting ball release heights in jump throws. Results show that SRH, JRH, BHJ and BHT differ significantly between leagues and playing positions. Furthermore, the prediction of BHT based on body height, SRH, JRH, and BHJ explained approx. 62 % of the variance in BHT compared to 15 % explained by the traditionally used jump and reach test (JRT). Thus, the factors measured in the test module seem to capture relevant information regarding the level of expertise and may be strong predictors of ball release height in jump throws. Results are discussed with respect to consequences for training and coaching in team handball
