Regional training supply and employees’ training participation

Using data from the National Educational Panel Study of 2009/2010, this paper investigates the correlation between regional training supply and employees’ training participation. Controlling for other regional factors such as the local unemployment rate, the educational level, the population density and the regional industry composition, the results indicate that training participation is significantly higher in regions with many firms in the training supply market. The predictive power of the other regional factors is rather minor.     

The thermal springs of Bockfjorden, Svalbard: II: selected aspects of trace element hydrochemistry

Waters from the Trollkjeldene (Troll springs) and Jotunkjeldene (Jotun springs) thermal springs on northern Svalbard have been analysed by ICP-AES, ICP-MS and IC techniques for a wide range of major and trace elements. Although it is plausible that the thermal waters originate from a deep reservoir in siliceous rocks, it appears that a significant component of their hydrochemical signature is derived from dissolution of higher-level Hecla Hoek marbles. Rare earth elements (REEs) show some degree of enrichment of heavy REEs in the water phase, relative to the marbles and to the travertines that precipitate from the waters. A strong positive Eu anomaly is also observed in the waters, suggesting preferential mobilisation of Eu under reducing conditions. The ratio Nb/Ta is rather well-preserved between the marbles, the waters and the travertines.     

Crossing boundaries in Facebook: Students’ framing of language learning activities as extended spaces

Young people’s interaction online is rapidly increasing, which enables new spaces for communication; the impact on learning, however, is not yet acknowledged in education. The aim of this exploratory case study is to scrutinize how students frame their interaction in social networking sites (SNS) in school practices and what that implies for educational language teaching and learning practices. Analytically, the study departs from a sociocultural perspective on learning, and adopts conceptual distinctions of frame analysis. The results based on ethnographic data from a Facebook group in English-learning classes, with 60 students aged between 13 and 16 from Colombia, Finland, Sweden and Taiwan indicate that there is a possibility for boundary crossing, which could generate extended spaces for collaborative language-learning activities in educational contexts where students combine their school subject of learning language and their communicative use of language in their everyday life. Such extended spaces are, however, difficult to maintain and have to be recurrently negotiated. To take advantage of young people’s various dynamic communicative uses of language in their everyday life in social media, the implementation of such media for educational purposes has to be deliberately, collaboratively and dynamically negotiated by educators and students to form a new language-learning space with its own potentials and constraints.     

Wird XML/EDI traditionelles EDI ablösen?

According to network effect theory, the benefit from using standards depends on the number of its users. In this article we examine, whether XML/EDI will replace traditional EDI and thus provide its users with positive network effects. Our contribution is based upon both network theory and the results of an empirical study among 130 major European companies. We conclude that most companies expect increasing diffusion of XML/EDI, with traditional EDI becoming less important at the same time. In addition, we believe that due to low setup and operating costs, XML/EDI will become increasingly attractive to small and medium-sized enterprises (SME). We reckon that the ?penguin effect” will not circumvent the transition from traditional EDI to XML/EDI and that the latter will be the key technology for exchanging business data in the future.     

Interfacial tension measurement of freon hydrates by droplet deposition and contact angle measurements

This paper describes a new experimental method for estimating the interfacial energy between hydrates and a variety of liquids. It is shown to be possible to create a smooth freon-hydrate surface on the interface between an aqueous phase and an oil phase, and to deposit a droplet of another hydrocarbon-based phase on the water-side of that surface. The contact angles of such droplets with the hydrate surfaces have been measured directly, and also estimated using the ADSA-P method, with a number of additives to the oil, the aqueous and the droplet phases. The contact angle measurements are shown to give reproducible results, suitable for estimating the effect of additives on the interfacial energy.     

The thermal springs of bockfjord, svalbard: occurrence and major ion hydrochemistry

The Troll and Jotun thermal springs of northern Svalbard, with temperatures of up to 25.6°C, are derived from a major fault forming the junction between Devonian sandstones and Proterozoic marbles, mica schists and gneisses. The Troll waters are dominated by Na–HCO₃ compositions and the Jotun waters by Na–Cl compositions. The pristine thermal water source has a sub-neutral pH and is highly reducing. Taken at face value, common geothermometers suggest temperatures at depth of 130–180°C for the Troll springs (corresponding to a depth of 1.6–2.3 km), with 10–30% thermal water diluted by 70–90% cold water. Such geothermometers may, however, be inappropriate to the cool, high CO₂ waters of Bockfjord, and real temperatures at depth and dilution factors are probably considerably lower. The salinity of the thermal water appears to be only partially derived from water–rock interaction; Br\Cl ratios suggest that seawater or possibly evaporites may be a source of chloride salinity.
