Representational predicaments for employees: Their impact on perceptions of supervisors\u27 individualized consideration and on employee job satisfaction

A representational predicament for a subordinate vis-à-vis his or her immediate superior involves perceptual incongruence with the superior about the subordinate\u27s work or work context, with unfavourable implications for the employee. An instrument to measure the incidence of two types of representational predicament, being neglected and negative slanting, was developed and then validated through an initial survey of 327 employees. A subsequent substantive survey with a fresh sample of 330 employees largely supported a conceptual model linking being neglected and negative slanting to perceptions of low individualized consideration by superiors and to low overall job satisfaction. The respondents in both surveys were all Hong Kong Chinese. Two case examples drawn from qualitative interviews illustrate and support the conceptual model. Based on the research findings, we recommend some practical exercises to use in training interventions with leaders and subordinates. © 2013 Copyright Taylor and Francis Group, LLC

The Sudbury Neutrino Observatory

The Sudbury Neutrino Observatory is a second generation water Cherenkov detector designed to determine whether the currently observed solar neutrino deficit is a result of neutrino oscillations. The detector is unique in its use of D2O as a detection medium, permitting it to make a solar model-independent test of the neutrino oscillation hypothesis by comparison of the charged- and neutral-current interaction rates. In this paper the physical properties, construction, and preliminary operation of the Sudbury Neutrino Observatory are described. Data and predicted operating parameters are provided whenever possible.Comment: 58 pages, 12 figures, submitted to Nucl. Inst. Meth. Uses elsart and epsf style files.

Towards a Theory of Online Social Rights

Abstract. Legitimacy, defined as fairness plus public good, is a proposed necessary online and physical community requirement,. As Fukuyama notes, legitimate societies tend to prosper, while others ignore legitimacy at their peril. Online communities are social-technical systems (STS), built upon social requirements as well as technical ones like bandwidth. As technical problems are increasingly solved, social problems like spam rise in relevance. If software can do almost anything in cyberspace, there is still the challenge of what should it do? Guidelines are needed. We suggest that online communities could decide information rights as communities decide physical action rights, by a legitimacy analysis. This requires a framework to specify social rights in information terms. To bridge the social-technical gap, between what communities want and technology does, rights must be translated into information terms. Our framework has four elements: information actors (people, groups, agents), information objects (persona, containers, items, comments, mail, votes), information methods (create, delete, edit, view, move, display, transfer and delegate), and the information context. The conclusions apply to any social-technical community, and we apply the framework to the case of Wikipedia

Does saltwater flushing reduce viability of diapausing eggs in ship ballast sediment?

Flushing of ballast tanks with seawater has been proposed to reduce the risk of invasion associated with residual ballast in \u27no ballast on board\u27 ships. The efficacy of this procedure, however, has not been determined. Using diapausing eggs isolated from ballast sediments - as well as from Lake Erie sediment - this study investigated the impact of salinity (0, 8 and 35‰) and temperature (10, 20 and 30°C) on the cumulative abundance and species richness of hatched zooplankton taxa. The rate and amount of hatching varied dramatically between sediments and across salinity-temperature regimes. Although exposure to saline water inhibited emergence of freshwater taxa during the exposure phase of all trials, mixed results were evident after diapausing eggs were returned to freshwater. The efficacy of salinity as a ballast treatment method was temperature dependent, although the direction of the effect was case-specific. Exposure of eggs to saline water was less effective at 10 and 30°C than at 20°C. Although flushing ballast tanks with open ocean water is expected to significantly reduce the number of active invertebrates living in residual ballast water (a potentially larger source of invaders), our results indicate that the most effective treatment conditions for reduction of diapausing egg viability is 8‰ salinity at 20°C. © 2006 Blackwell Publishing Ltd
