The Liverpool Violence Assessment: an investigator-based measure of serious violence

CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2003
Rajan Nathan
Background Antisocial personality disorder (ASPD) identifies adults with persistent offending behaviour and social dysfunction. However, it lacks discrimination within high-risk and criminal populations and gives little indication of an individual's history of violence. Existing measures of violence have significant limitations. The Liverpool Violence Assessment (LiVA) is an investigator-based standardized interview for measuring patterns of violence. Method A total of 61 male prisoners who had been sentenced for serious violent offences were interviewed using the LiVA and the Structured Clinical Interview for DSM IV antisocial personality disorder and alcohol and drug dependence. Official records of offending were examined. Results The inter-rater reliability for the LiVA was high. There were significant correlations between histories of violence assessed by the LiVA and official records, but the frequency of self-reported violence was much higher than in the official records. Antisocial personality disorder was associated with increased violence. However, analyses revealed marked variability of the levels of violence among those with antisocial personality disorder and contrasting patterns of association of violence with antisocial personality disorder depending on the context. Conclusion The LiVA is a reliable and valid measure of the patterns and characteristics of violence. The findings suggest that the causes of violence should be studied in their own right and not only as a feature of ASPD. Copyright © 2003 Whurr Publishers Ltd. [source]


Effect of the challenger experience on elementary children's attitudes to science

JOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 10 2002
Tina Jarvis
This research explored how the Challenger experience influenced over 655 elementary boys' and girls' general attitudes to science and space during the 5 months after their visit by examining their responses to four different attitude scales. These were administered to the 10- to 11-year-olds immediately before and after the Challenger experience as well as 2 and 5 months later. Knowledge tests were also administered before and after the visit. A sample of children completed an existing measure of anxiety. Although there were mainly positive outcomes immediately after the Challenger experience, there were some negative effects. There were also noticeable differences between boys and girls. Some 24% of pupils were inspired to become scientists. There was also less fear of space travel with a greater appreciation of the use of science to protect the planet after the visit. Most girls improved and maintained their attitudes toward science in society. A sizeable number of pupils were relatively unaffected by the experience and there was a significant negative effect on a small group of anxious girls. There are indications that previsit preparation and careful choice of roles during the simulation are important. © 2002 Wiley Periodicals, Inc. J Res Sci Teach 39: 979,1000, 2002 [source]


A new relative skill measure for games with chance elements

MANAGERIAL AND DECISION ECONOMICS, Issue 5 2004
Marcel Dreef
An interesting aspect of games is the relative extent to which a player can positively influence his results by making appropriate strategic choices. This question is closely related to the issue of how to distinguish between games of skill and games of chance. The distinction between these two types of games is definitely interesting from a juridical point of view. In this paper we present a modification of an existing measure of the skill level of a game, which has served as a juridical tool for the classification of games. The main difference is that this new definition does not automatically classify incomplete information games without chance moves as games of skill. Copyright © 2004 John Wiley & Sons, Ltd.

Psychometric properties of the Trauma Assessment for Adults

DEPRESSION AND ANXIETY, Issue 2 2009
Matt J. Gray Ph.D.
Abstract Background: The Trauma Assessment for Adults (TAA) was developed to facilitate the assessment of exposure to traumatic events that could result in posttraumatic stress disorder (PTSD). The TAA inquires about numerous potentially traumatic events that an individual may have experienced. Although the TAA has been used extensively for clinical and research purposes, its psychometric properties have never been formally evaluated. The objective of the present investigation was to evaluate the psychometric properties of this frequently used measure. Methods: The studies reported here describe the performance of the TAA in two samples,college undergraduates (N=142) and community mental health center clients (N=67). Among undergraduates, 1-week temporal stability was evaluated and, in both samples, item- and scale-level convergence of the TAA with an established trauma exposure measure was assessed. Convergence of the TAA with clinically related constructs was also evaluated. Results: The TAA exhibited adequate temporal stability (r=.80) and satisfactory item-level convergence with existing measures of trauma history among college students. In the clinical sample, the TAA again converged well with an established measure of trauma exposure (r=.65). It was not as strongly predictive, in either sample, of trauma-related distress relative to an alternate trauma exposure measure. Conclusion: Although it performs satisfactorily, the TAA does not appear to be superior to other existing measures of trauma exposure. Depression and Anxiety, 2009. © 2008 Wiley-Liss, Inc. [source]


Three Meanings of Intergenerational Mobility

ECONOMICA, Issue 272 2001
Dirk Van De Gaer
We axiomatize three different motivations for being concerned about intergenerational mobility: mobility as a description of movement, as an indication of equality of opportunity, and as an indication of equality of life chances. These three motivations are shown to be incompatible. None of the existing measures is acceptable as an indicator of equality of opportunity or equality of life chances. We propose two new measures of intergenerational mobility which more adequately reflect these concerns. [source]


The spatial epidemiology of cocaine, methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA) use: a demonstration using a population measure of community drug load derived from municipal wastewater

ADDICTION, Issue 11 2009
Caleb J. Banta-Green
ABSTRACT Aims To determine the utility of community-wide drug testing with wastewater samples as a population measure of community drug use and to test the hypothesis that the association with urbanicity would vary for three different stimulant drugs of abuse. Design and participants Single-day samples were obtained from a convenience sample of 96 municipalities representing 65% of the population of the State of Oregon. Measurements Chemical analysis of 24-hour composite influent samples for benzoylecgonine (BZE, a cocaine metabolite), methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA). The distribution of community index drug loads accounting for total wastewater flow (i.e. dilution) and population are reported. Findings The distribution of wastewater-derived drug index loads was found to correspond with expected epidemiological drug patterns. Index loads of BZE were significantly higher in urban areas and below detection in many rural areas. Conversely, methamphetamine was present in all municipalities, with no significant differences in index loads by urbanicity. MDMA was at quantifiable levels in fewer than half the communities, with a significant trend towards higher index loads in more urban areas. Conclusion This demonstration provides the first evidence of the utility of wastewater-derived community drug loads for spatial analyses. Such data have the potential to improve dramatically the measurement of the true level and distribution of a range of drugs. Drug index load data provide information for all people in a community and are potentially applicable to a much larger proportion of the total population than existing measures. [source]


Measuring health polarization with self-assessed health data

HEALTH ECONOMICS, Issue 9 2007
Benedicte ApoueyArticle first published online: 20 AUG 200
Abstract This paper proposes an axiomatic foundation for new measures of polarization that can be applied to ordinal distributions such as self-assessed health (SAH) data. This is an improvement over the existing measures of polarization that can be used only for cardinal variables. The new measures of polarization avoid one difficulty that the related measures for evaluating health inequalities face. Indeed, inequality measures are mean based, and since only cardinal variables have a mean, SAH has to be cardinalized to compute a mean, which can then be used to calculate an inequality measure. In contrast, the new polarization measures are median based and hence do not require to impose cardinal scaling on the categories. After deriving the properties of these new polarization measures, we provide an empirical illustration using data from the British Household Panel Survey that demonstrates that SAH polarization is also a relevant question on empirical grounds, and that the polarization measures are adequate to evaluate polarization phenomena whereas inequality measures are not adequate in these cases.

Emotional Intelligence: Toward Clarification of a Concept

INDUSTRIAL AND ORGANIZATIONAL PSYCHOLOGY, Issue 2 2010
CARY CHERNISS
There has been much confusion and controversy concerning the concept of emotional intelligence (EI). Three issues have been particularly bothersome. The first concerns the many conflicting definitions and models of EI. To address this issue, I propose that we distinguish between definitions and models and then adopt a single definition on which the major theorists already seem to agree. I further propose that we more clearly distinguish between EI and the related concept of emotional and social competence (ESC). The second issue that has generated concern is the question of how valid existing measures are. After reviewing the research on the psychometric properties of several popular tests, I conclude that although there is some support for many of them, they all have inherent limitations. We need to rely more on alternative measurement strategies that have been available for some time and also develop new measures that are more sensitive to context. The third area of contention concerns the significance of EI for outcomes such as job performance or leadership effectiveness. Recent research, not available to earlier critics, suggests that EI is positively associated with performance. However, certain ESCs are likely to be stronger predictors of performance than EI in many situations. Also, EI is likely to be more important in certain kinds of situations, such as those involving social interaction or significant levels of stress. Context makes a difference. [source]


The Pregnant Women with HIV Attitude Scale: development and initial psychometric evaluation

tyer-viola l.a. & duffy m.e. (2010) The Pregnant Women with HIV Attitude Scale: development and initial psychometric evaluation. Journal of Advanced Nursing,66(8), 1852,1863. Abstract Title.,The Pregnant Women with HIV Attitude Scale: development and initial psychometric evaluation. Aim., This paper is a report of the development and initial psychometric evaluation of the Pregnant Women with HIV Attitude Scale. Background., Previous research has identified that attitudes toward persons with HIV/AIDS have been judgmental and could affect clinical care and outcomes. Stigma towards persons with HIV has persisted as a barrier to nursing care globally. Women are more vulnerable during pregnancy. An instrument to specifically measure obstetric care provider's attitudes toward this population is needed to target identified gaps in providing respectful care. Methods., Existing literature and instruments were analysed and two existing measures, the Attitudes about People with HIV Scale and the Attitudes toward Women with HIV Scale, were combined to create an initial item pool to address attitudes toward HIV-positive pregnant women. The data were collected in 2003 with obstetric nurses attending a national conference in the United States of America (N = 210). Content validity was used for item pool development and principal component analysis and analysis of variance were used to determine construct validity. Reliability was analysed using Cronbach's Alpha. Results., The new measure demonstrated high internal consistency (alpha estimates = 0·89). Principal component analysis yielded a two-component structure that accounted for 45% of the total variance: Mothering-Choice (alpha estimates = 0·89) and Sympathy-Rights (alpha estimates = 0·72). Conclusion., These data provided initial evidence of the psychometric properties of the Pregnant Women with HIV Attitude Scale. Further analysis is required of the validity of the constructs of this scale and its reliability with various obstetric care providers. [source]


Measuring beta-diversity from taxonomic similarity

JOURNAL OF VEGETATION SCIENCE, Issue 6 2007
Giovanni Bacaro
Abstract Question: The utility of beta (,-) diversity measures that incorporate information about the degree of taxonomic (dis)similarity between species plots is becoming increasingly recognized. In this framework, the question for this study is: can we define an ecologically meaningful index of ,-diversity that, besides indicating simple species turnover, is able to account for taxonomic similarity amongst species in plots? Methods: First, the properties of existing measures of taxonomic similarity measures are briefly reviewed. Next, a new measure of plot-to-plot taxonomic similarity is presented that is based on the maximal common subgraph of two taxonomic trees. The proposed measure is computed from species presences and absences and include information about the degree of higher-level taxonomic similarity between species plots. The performance of the proposed measure with respect to existing coefficients of taxonomic similarity and the coefficient of Jaccard is discussed using a small data set of heath plant communities. Finally, a method to quantify ,-diversity from taxonomic dissimilarities is discussed. Results: The proposed measure of taxonomic ,-diversity incorporates not only species richness, but also information about the degree of higher-order taxonomic structure between species plots. In this view, it comes closer to a modern notion of biological diversity than more traditional measures of ,-di-versity. From regression analysis between the new coefficient and existing measures of taxonomic similarity it is shown that there is an evident nonlinearity between the coefficients. This nonlinearity demonstrates that the new coefficient measures similarity in a conceptually different way from previous indices. Also, in good agreement with the findings of previous authors, the regression between the new index and the Jaccard coefficient of similarity shows that more than 80% of the variance of the former is explained by the community structure at the species level, while only the residual variance is explained by differences in the higher-order taxonomic structure of the species plots. This means that a genuine taxonomic approach to the quantification of plot-to-plot similarity is only needed if we are interested in the residual system's variation that is related to the higher-order taxonomic structure of a pair of species plots.

Fund Manager Use of Public Information: New Evidence on Managerial Skills

THE JOURNAL OF FINANCE, Issue 2 2007
MARCIN KACPERCZYK
ABSTRACT We show theoretically that the responsiveness of a fund manager's portfolio allocations to changes in public information decreases in the manager's skill. We go on to estimate this sensitivity (RPI) as the R2 of the regression of changes in a manager's portfolio holdings on changes in public information using a panel of U.S. equity funds. Consistent with RPI containing information related to managerial skills, we find a strong inverse relationship between RPI and various existing measures of performance, and between RPI and fund flows. We also document that both fund- and manager-specific attributes affect RPI. [source]


Measuring Human Capital Like Physical Capital: What Does It Tell Us?

BULLETIN OF ECONOMIC RESEARCH, Issue 3 2002
Ruth Judson
In this paper, I develop a measure of human capital stock that is similar to measuring physical capital by its replacement cost. This measure builds on measures of average educational attainment of the labour force. While it is far from an ideal measure, it is an interesting complement to the educational attainment series and other existing measures of human capital accumulation. In cross,country panel regressions, use of this measure of human capital accumulation yields a positive and significant, but relatively small (about ten per cent) elasticity with percapita GDP growth. Unlike physical capital, the stock of human capital as a share of GDP increases with GDP. This is consistent with the Barro et al. (1995) model of growth with non,mobile human capital and with some predictions of Romer's (1990) model of endogenous growth, but it is not consistent with the predictions of some other growth models.

Development of the cognitive processing of trauma scale

CLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 5 2002
Rhonda M. Williams
We developed a 17-item scale to measure cognitive processing of traumatic experiences in two samples of college students. The Cognitive Processing of Trauma Scale (CPOTS) measures five aspects of cognitive processing: (1) Positive Cognitive Restructuring, (2) Downward comparison, (3) Resolution, (4) Denial and (5) Regrets. Confirmatory Factor Analysis confirmed the factor structure of the scale, and reliability was further established by computing the internal consistency and test,retest reliability of each subscale. Discriminant and convergent validity for the CPOTS were demonstrated by correlating the subscales with two existing measures, the Impact of Event Scale and the Stress Related Growth Scale. The scale is recommended for use in empirical studies incorporating written or spoken disclosure about a trauma as an intervention, and should also be considered for clinical use in populations who have experienced a major stressor or trauma.
