The study of Li-graphite intercalation processes in several electrolyte systems using in situ X-ray diffraction

Abstract: The behavior of graphite electrodes in various electrolyte solutions was explored using in situ x‐ray diffraction in conjunction with chronopotentiometry The solvent systems studied included ethylene and diethyl carbonate mixtures (EC‐DEC), propylene carbonate (PC), tetrahydrofuran (THF), and dimethyl carbonate (DMC) These studies revealed that the above systems can be divided into three classes EC‐DEC and water contaminated DMC are solvent systems in which highly passivating and protective surface films are precipitated on the carbon at potentials much higher than the intercalation potentials Therefore, graphite electrodes behave reversibly in these solutions and are stable on Li intercalation‐deintercalation cycling An opposite case occurs with PC and THF, where the carbon is destroyed before or during the intercalation processes, and therefore graphite anodes behave totally irreversibly in these systems In an intermediate case (dry DMC is a good example), a passivating layer is formed on the carbon at a potential higher than where Li intercalation occurs, but it is not sufficient to protect the carbon totally and therefore the electrode is slowly destroyed by cycling

Celebrity Contagion and the Value of Objects

Abstract: Why do people purchase objects that were once owned by celebrities, such as film stars or politicians, and also by despised individuals, such as serial killers and notorious dictators? The present studies examine three potential explanations: mere associations, market demands, and contagion (the belief that these objects contain some remnants of their previous owners). Results indicate that while market demands do play a role, contagion appears to be the critical factor affecting the valuation of celebrity possessions. Manipulating the degree of physical contact that a celebrity has with an object dramatically influences consumers’ willingness to purchase it, and individual differences in sensitivity to contagion moderate this effect. Additionally, the valuation of celebrity possessions is principally explained by measures of contagion, and subliminally activating the concept of contagion changes consumers’ willingness to purchase celebrity objects. Theoretical and practical implications of these findings...

Bridging intention and behavior of knowledge sharing

Abstract: Purpose – This paper seeks to present an innovative scale that sheds light on the ways in which intentions to share explicit and tacit knowledge impact actual knowledge-sharing behavior. Design/methodology/approach – Survey data were collected from a total of 278 hi-tech workers. Structural equation modeling (SEM) was used to assess the research model. Findings – SEM shows that the intention to share explicit knowledge influences explicit knowledge-sharing behavior to an equal extent both directly and indirectly. By contrast tacit knowledge-sharing behavior is influenced directly to a greater extent by the intention to share tacit knowledge and less indirectly by the intention to share explicit knowledge. Research limitations/implications – The study provides a potential tool that may be applied by managers for the purpose of measuring explicit and tacit knowledge-sharing intention and behavior. Its limitations are due to the limited socio-economic and geographic variability of the companies and people that were studied, which may need further studies to substantiate. Originality/value – Whereas there is a consensus as to the need for and the benefits of sharing knowledge, there are no tools for measuring the roots of sharing behavior. The scale presented here captures the underlying intention, measures it, and assesses the resulting behavior.

The Syntactic Forms of Predication

Abstract: In Chapter 2 I argued for a syntactic predication relation which cannot be reduced to a thematic relation. I argued that this syntactic relation is a saturation relation between a predicate and an argument, its subject, and I claimed that there was a locality relation between subject and predicate, namely that subject and predicate have to c-command each other. The discussion in Chapter 2 concentrated on primary, or clausal, predication relations, and in particular on the predication relation within small clause complements of consider and other ECM verbs, where the predication relation is realised in its simplest form. By this I mean that small clause predication has two basic characteristics, and the predication relation is more complicated if either of these properties is changed. Small clause predication is direct predication, by which I mean that the subject and predicate c-command each other, and it is primary predication, which means that the subject and predicate form a constituent. If either of these properties does not hold of a predication relation, then we need to say something more than what was said in Chapter 2.
