Perceptions of control in the victims of school bullying : the importance of early intervention

Improvements in anti-bullying strategies are likely to depend upon a greater understanding of the psychological processes at work. Transactional theories of coping may be appropriate models to use when examining how the victims of bullying cope with victimization. Research has started to examine the coping strategy aspects of such theories but has neglected the process of appraisal. The current paper aims to address this by examining the perceptions of control in the victims of bullying, and how these are influenced by such variables as gender and the severity, persistence and type of bullying experienced. A self-report questionnaire examining coping responses and perceptions of control regarding the bullying situation was administered to 348 children aged nine to 11 years. Data from the victims of bullying (N = 184) revealed that girls felt less in control of frequent bullying than infrequent bullying, a trend not evident in boys (p < 0.05). In addition, a significantly higher proportion of the male victims of bullying felt more in control than female victims (p < 0.01). Finally, victims of short-term bullying were significantly more likely to feel in control than were victims of longer-term bullying (p < 0.05). The complex relationship between gender, perceptions of control, and the persistence and frequency of bullying has implications for early intervention and for professionals working with the victims of bullying

Asymptotic Weight Enumerators of Randomly Punctured, Expurgated, and Shortened Code Ensembles

In this paper, we examine the effect of random puncturing, expurgating, and shortening on the asymptotic weight enumerator of certain linear code ensembles. We begin by discussing the actions of the three alteration methods on individual codes. We derive expressions for the average resulting code weight enumerator under each alteration. We then extend these results to the spectral shape of linear code ensembles whose original spectral shape is known, and demonstrate our findings on two specific code ensembles: the Shannon ensemble and the regular (j, k) Gallager ensemble

Semi-leptonic decays heavy-light to heavy light

We present results for the QCD matrix elements involved in semi-leptonic decays of B-mesons into pseudo scalar heavy light states. The application of NRQCD heavy quarks allows for quark masses around the physical b-quark. We investigate the dependence of the form factors on the external momenta and looked at the mass dependence at zero recoil. For the first time, results for radially excited decay products are presented.Comment: 3 pages LaTeX, 5 figures, Talk given at LATTICE99(Heavy Quarks), June 29th to July 3rd, 1999, Pisa, Ital

WOULD PEOPLE RATHER PAY TAXES OR TRADE TAXES TO PAY FOR ENVIRONMENTAL GOODS? A GROUND WATER QUALITY CASE

The potential sensitivity of environmental resource valuation to payment vehicles is of interest to researchers and decision-makers involved in estimating and applying these numbers. A conceptual model is developed which provides insight into how the different payment vehicles of a special tax and a tax reallocation affects the willingness to pay (WTP) for environmental goods. Hypothesis testing using contingent valuation data suggests WTP with a tax reallocation is higher than WTP with a special tax for ground water quality protection in Georgia and Maine.Environmental Economics and Policy, Public Economics,

A META ANALYSIS OF CONTINGENT VALUES FOR GROUNDWATER QUALITY IN THE UNITED STATES

This paper provides an overview and a meta analysis of existing US contingent valuation studies of groundwater quality. Using 108 observations from 14 studies, core economic variables, risk variables, and elicitation effects are found to systematically influence groundwater values. Other research design features are also investigated.Resource /Energy Economics and Policy,
