Several Dimensions (several + dimension)
Selected AbstractsPsychosocial treatment refusal in personality disorder: a comparative studyPERSONALITY AND MENTAL HEALTH, Issue 2 2010Marco Chiesa There is a paucity of research concerning the identification of features implicated in treatment refusal by personality disorder. This study aims to identify clinical factors that may affect treatment uptake to a specialist psychosocial programme for personality disorder. Following a lengthy assessment, 39 patients (out of a total of 60 referrals) were offered entry to the programme. Fourteen patients who did not take up the offer of treatment and 25 patients who started the programme are compared on a number of demographic, diagnostic and clinical variables, including severity of presentation and subjective experience of the assessment process. The results show that, relative to non-refusers, refusers were significantly younger, single, had a higher frequency of borderline personality disorder (BPD), experienced a less satisfactory relationship with the assessing clinician and had lower treatment expectations. Several dimensions measuring severity of presentation did not make a significant contribution to treatment uptake. A logistic regression analysis showed that assessment-related variables total score and BPD were significant predictors of treatment refusal. The low sample size and the specialist nature of the service are important limitations with regard to the generalizability of the findings. Copyright © 2010 John Wiley & Sons, Ltd. [source] Children's Housing Environments: Welfare Families in IowaFAMILY & CONSUMER SCIENCES RESEARCH JOURNAL, Issue 2 2006Seongyeon Auh This study uses qualitative data to examine how rural low-income women confront the housing needs of their young children in the midst of changes in public policy. The focus is on the strategies employed and the difficulties faced in the provision of safe, affordable and stable homes. The data are drawn from in-home interviews conducted every 6 months with 13 mothers who were welfare-dependent at the start of the research. The investigation depicts several dimensions of the circumstances of poor children that have not had much previous attention in the literature: serial housing inadequacy and chronic mobility. Several families with children with disabilities reported severe housing deficiencies. This research provides initial evidence of the important role of housing in promoting the goals of family stability and economic self-sufficiency as well as the need to improve health and developmental outcomes for children living in poverty. [source] Experimental Evidence of the Knowledge Gap: Message Arousal, Motivation, and Time DelayHUMAN COMMUNICATION RESEARCH, Issue 4 2008Maria Elizabeth Grabe This study experimentally tested the knowledge gap from an information processing perspective. Specifically, knowledge acquisition was investigated under conditions of medium and low news message arousal, with time delay. Results show the persistence of a knowledge gap, particularly for low arousing messages. In fact, at low levels of message arousal, the gap is larger than at medium levels of arousal. Some existing research suggests that message salience explains the knowledge gap. Findings from this study show that information processing aptitude may also be a significant factor. Measures of several dimensions of participant motivation to cognitively engage with news messages were added as covariates to statistical analyses. These were found not to affect the knowledge gap outcomes in this data set. Résumé Des preuves expérimentales de l,écart des savoirs : intérêt des messages, motivation et décalage de temps Cette étude a testé expérimentalement l'écart des savoirs à partir d,une perspective du traitement de l'information. En particulier, l,acquisition des connaissances fut étudiée dans des conditions d'intérêt moyen et faible des messages d,information, avec un décalage de temps. Les résultats démontrent la persistance d'un écart des savoirs, particulièrement pour les messages à faible intérêt. En fait, l,écart est plus large à de faibles niveaux d'intérêt qu,à des niveaux moyens. Des recherches préalables suggèrent que la prépondérance des messages explique l'écart des savoirs. Les résultats de cette étude démontrent que les aptitudes de traitement de l,information peuvent aussi être un facteur important. Les mesures de plusieurs dimensions de la motivation des participants à s'impliquer cognitivement avec les messages informatifs furent ajoutées comme covariables aux analyses statistiques. Elles n,ont pas paru avoir d'effets sur les résultats de l,écart des savoirs dans cet ensemble de données. Mots clés : écart des savoirs, modèle de capacité limitée du traitement motivé des messages médiatiques (limited capacity model of mediated motivated message processing), cognition, statut socioéconomique, éducation, intérêt des messages, mémoire, décalage de temps, motivation, prépondérange des messages, informations Abstract Ein experimenteller Nachweis der Wissenskluft: Botschaftserregung, Motivation und Zeitverzögerung Diese Studie testete die Wissensklufthypothese experimentell aus einer Informationsverarbeitungsperspektive. Insbesondere wurde die Wissensaneignung bei Nachrichten unter Bedingungen eines mittleren und niedrigen Botschaftserregungsniveaus mit Zeitverzögerung untersucht. Die Ergebnisse zeigen das Fortdauern einer Wissenskluft insbesondere bei wenig erregenden Botschaften. Tatsächlich ist die Kluft bei einem geringen Niveau der Botschaftserregung größer als bei mittleren Erregungsniveaus. Bestehende Forschung legt nahe, dass die Wissenskluft durch die Botschaftssalienz erklärt werden kann. Die Ergebnisse dieser Studie zeigen, dass die Informationsverarbeitungsfähigkeit ebenfalls ein signifikanter Faktor sein könnte. Messungen verschiedenen Dimensionen der Motivation der Teilnehmer, sich kognitiv mit den Nachrichtenbotschaften zu beschäftigen, wurden als Kovariate in die statistische Analyse einbezogen. Diese zeigten keine Auswirkungen auf die Wissenskluft in dieser Stichprobe. Resumen La Evidencia Experimental de la Brecha de Conocimiento: La Excitación del Mensaje, la Motivación, y la Demora de Tiempo Este estudio puso a prueba experimental la brecha de conocimiento desde la perspectiva del procesamiento de la información. Específicamente, la adquisición de conocimiento fue investigada bajo condiciones de excitación mediana y baja a los mensajes de noticias, con una demora de tiempo. Los resultados muestran la persistencia de la brecha de conocimiento, particularmente en los mensajes de excitación baja. De hecho, en los niveles de excitación de mensaje bajos la brecha fue mayor que en los niveles de excitación medianos. Algunas investigaciones existentes sugieren que la notabilidad del mensaje explica la brecha de conocimiento. Los hallazgos de este estudio muestran que la aptitud de procesamiento de información puede ser un factor significante también. Las medidas de varias dimensiones de la motivación del participante para involucrarse cognitivamente con los mensajes de noticias fueron agregadas como covarianzas a los análisis estadísticos. Se encontró que éstos no afectaron los resultados de la brecha de conocimiento en este grupo de datos. Palabras claves: brecha de conocimiento, modelo de capacidad limitada de procesamiento de mensajes motivadores mediatizados, cognición, estatus socioeconómico, educación, excitación del mensaje, memoria, demora de tiempo, motivación, notabilidad del mensaje, noticias.

H. Robert Abstract Objective This study was designed to establish the validity and reliability of the apathy inventory (IA), a rating scale for global assessment of apathy and separate assessment of emotional blunting, lack of initiative, and lack of interest. Method Information for the IA can be obtained from the patient or from a caregiver. We evaluated 115 subjects using the IA, consisting of 19 healthy elderly subjects, 24 patients with Mild Cognitive Impairment (MCI), 12 subjects with Parkinson's disease (PD) and 60 subjects with Alzheimer's disease (AD). Results Internal consistency, item reliability, and between,rater reliability were high. A test,retest reliability study demonstrated that caregiver responses to IA questions were stable over short intervals. A concurrent validity study showed that the IA assesses apathy as effectively as the Neuro Psychiatric Inventory apathy domain. In the caregiver-based evaluation, AD subjects had significantly higher scores than controls, both for global apathy score and for the lack of interest dimension. When the AD patients were subdivided according to diagnostic criteria for apathy, apathetic patients had significantly higher scores than non apathetic patients. With the patient-based evaluations, no differences were found among the AD, MCI and control groups. The scores in the patient-based evaluations were only higher for the PD group versus the control subjects. The results also indicated that AD patients had poor awareness of their emotional blunting and lack of initiative. Conclusions The IA is a reliable method for assessing in demented and non-demented elderly subjects several dimensions of the apathetic syndrome, and also the subject's awareness of these symptoms.

Within the framework of the European Employment Strategy, the European Union has defined a set of indicators to monitor employment quality , the so-called Laeken indicators. This article discusses and implements these indicators. From a theoretical perspective, it shows that the concept of work quality encompasses several dimensions, which are likely to be related to national institutions, particularly industrial relations and welfare systems. It then proceeds with a comparative analysis of quality in work across the 27 Member States, which confirms the existence of several models in Europe and suggests that the Laeken indicators should be supplemented by additional measures. [source] Can niche use in red and grey squirrels offer clues for their apparent coexistence?JOURNAL OF APPLIED ECOLOGY, Issue 6 2002Jenny Bryce Summary 1Introduced species are, world-wide, one of the most serious threats to biodiversity. Grey squirrels Sciurus carolinensis are one of many introduced species to have threatened a native congener; they are thought to have replaced red squirrels Sciurus vulgaris throughout much of the UK as a result of competition. The rate of competitive replacement may be influenced by habitat composition, with some red squirrel populations persisting for prolonged periods in the presence of greys in predominantly coniferous forest. 2Here the similarity of red and grey squirrels' pattern of habitat use was investigated in Craigvinean forest in Scotland, UK, a site that has experienced apparent coexistence for up to 30 years. Overlap was examined in several dimensions: spatial overlap of home ranges, dynamic association and niche overlap. Habitat selection was examined at three levels: selection of core home range areas, selection of tree species within the home range, and the characteristics of patches used intensively by each squirrel species in comparison with random locations within their home range. 3Although there was overlap between red and grey squirrel ranges, there were clear differences in the macrohabitats utilized, with red squirrels selecting areas of Norway spruce Picea abies and grey squirrels selecting riparian corridors of mixed woodland for their home ranges. Within their home ranges, habitat selection by individual red and grey squirrels was similar, but again with reds selecting Norway spruce and greys selecting patches of mixed conifers and broad-leaved trees. As no habitat variables consistently affected the microdistribution of red and grey squirrels within blocks or ,stands' of trees, stands that were used were thought to constitute good and relatively homogeneous habitats for squirrels of either species. 4There was no evidence to suggest that red and grey squirrels avoided using the same areas at the same time, and potential niche overlap was considerable (0·77). However, partitioning of habitats may have reduced competition between red and grey squirrels and hence have contributed to red squirrel persistence at this site. 5This work (i) reinforces earlier proposals that forest management offers a promising tool to assist the conservation of red squirrels; (ii) raises the issue of determining the spatial scale at which coexistence operates; and (iii) offers an illustration of how the management of invasive species can be mediated through the manipulation of niche availability. [source] Market mavenism and consumer self-confidenceJOURNAL OF CONSUMER BEHAVIOUR, Issue 3 2008Ronald A. Clark The purpose of this study was to test hypothesized associations between market mavenism and consumer self-confidence (CSC). A survey of 190 US consumers provided the data. The results showed significant relationships between mavenism and several dimensions of CSC, and regression analysis emphasized the relationships with two of these: information acquisition (confidence in the ability to obtain and use marketplace information) and social outcomes decision making (confidence in obtaining positive reactions from others). These findings both enrich our knowledge of the psychology of market mavenism by suggesting some motivations for these behaviors and suggest marketing strategies can be fine-tuned to appeal more effectively to this important segment of consumers.

[source] Evaluating predictive performance of value-at-risk models in emerging markets: a reality checkJOURNAL OF FORECASTING, Issue 2 2006Yong Bao Abstract We investigate the predictive performance of various classes of value-at-risk (VaR) models in several dimensions,unfiltered versus filtered VaR models, parametric versus nonparametric distributions, conventional versus extreme value distributions, and quantile regression versus inverting the conditional distribution function. By using the reality check test of White (2000), we compare the predictive power of alternative VaR models in terms of the empirical coverage probability and the predictive quantile loss for the stock markets of five Asian economies that suffered from the 1997,1998 financial crisis. The results based on these two criteria are largely compatible and indicate some empirical regularities of risk forecasts. The Riskmetrics model behaves reasonably well in tranquil periods, while some extreme value theory (EVT)-based models do better in the crisis period. Filtering often appears to be useful for some models, particularly for the EVT models, though it could be harmful for some other models. The CaViaR quantile regression models of Engle and Manganelli (2004) have shown some success in predicting the VaR risk measure for various periods, generally more stable than those that invert a distribution function. Overall, the forecasting performance of the VaR models considered varies over the three periods before, during and after the crisis. Copyright © 2006 John Wiley & Sons, Ltd. [source] Verifying the Multi-Dimensional Nature of Metropolitan Land Use: Advancing the Understanding and Measurement of SprawlJOURNAL OF URBAN AFFAIRS, Issue 3 2005Jackie Cutsinger Common patterns of variation in these indices across metropolitan areas are discerned using correlation and factor analyses. We find that: (1) seven principal components best summarize the dimensions of housing and employment land uses, (2) metro areas often exhibit both high and low levels of sprawl-like patterns across the seven components, and (3) housing and employment aspects of sprawl-like patterns differ in nature. Thus, land use patterns prove multi-dimensional in both theory and practice. Exploratory analyses indicate: (1) little regional variation in land use patterns, (2) metro areas with larger populations are more dense/continuous with greater housing centrality and concentration of employment in the core, (3) older areas have higher degrees of housing concentration and employment in the core, (4) constrained areas evince greater density/continuity, and (5) inter-metropolitan variations in several dimensions of land use patterns are not well explained by population, age, growth patterns, or topographical constraints on development. Results imply that policymakers must carefully unravel which land use dimension is causing undesirable outcomes, and then devise precise policy instruments to change only this dimension. [source] How Many Labour Force States?LABOUR, Issue 2 2006An Analysis Based on the British Household Panel Survey (BHPS) The goal is to examine whether there are statistically significant differences between the unemployed and non-participants, as well as inside each of the two groups, considering their transitions in the job market. Using logistic regression for a pooled cross-section time-series sample of employed as well as non-employed persons, three different Out of Work subgroups are identified: Seeking Out of Work, Attached Out of Work, and Voluntary Out of Work. The first group can be broadly assimilated to the official definition of unemployment, International Labour Organization unemployment, whereas all the others are usually classified as economically inactive. Nonetheless, the last two groups are characterized by significantly different transition rates, showing a behaviourally distinct attitude in their labour market dynamics. This result points out that the aggregate non-employment has several dimensions, which are not caught by the distinction between unemployment and economic inactivity, and should be accounted for by policy makers and researchers. [source] Seeing the Past: Visual Media in ArchaeologyAMERICAN ANTHROPOLOGIST, Issue 2 2006RUTH M. VAN DYKE As digital media become increasingly affordable and accessible, visual representation in archaeology is expanding across several dimensions. In this essay, I examine some emerging forms of visual media in archaeology, including online documentaries, maps and photographs, hypermedia, experimental films, and peripatetic video. Visual media offer powerful opportunities for engagement with the public. In addition, archaeologists are finding new ways to use the visual in interpretation, analysis, and critique. Experimental visual works often are self-consciously reflexive, questioning and exposing the ways archaeological knowledge is constructed, represented, and disseminated. [source] General theory of domain decomposition: Indirect methodsNUMERICAL METHODS FOR PARTIAL DIFFERENTIAL EQUATIONS, Issue 3 2002Ismael Herrera Abstract According to a general theory of domain decomposition methods (DDM), recently proposed by Herrera, DDM may be classified into two broad categories: direct and indirect (or Trefftz-Herrera methods). This article is devoted to formulate systematically indirect methods and apply them to differential equations in several dimensions. They have interest since they subsume some of the best-known formulations of domain decomposition methods, such as those based on the application of Steklov-Poincaré operators. Trefftz-Herrera approach is based on a special kind of Green's formulas applicable to discontinuous functions, and one of their essential features is the use of weighting functions which yield information, about the sought solution, at the internal boundary of the domain decomposition exclusively. A special class of Sobolev spaces is introduced in which boundary value problems with prescribed jumps at the internal boundary are formulated. Green's formulas applicable in such Sobolev spaces, which contain discontinuous functions, are established and from them the general framework for indirect methods is derived. Guidelines for the construction of the special kind of test functions are then supplied and, as an illustration, the method is applied to elliptic problems in several dimensions. A nonstandard method of collocation is derived in this manner, which possesses significant advantages over more standard procedures. © 2002 Wiley Periodicals, Inc.

Individuals are divided into various subgroups along several dimensions, namely region of residence, employment status, occupation and age. The change in inequality over time, between and within these subgroups is studied, and the bootstrap method is used to establish whether these changes are statistically significant. [source] Technological Innovativeness as a Moderator of New Product Design Integration and Top Management SupportTHE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 3 2000Morgan Swink Many war stories, as well as a number of empirical research studies, point to the value of design integration and top management support in new product development (NPD) efforts, where design integration is conceptualized as the coordination of product and process design activities performed by various organizational groups. However, some emerging evidence suggests that these aspects of program management are not equally valuable in all NPD contexts. Furthermore, the benefits of these approaches may not extend to all dimensions of NPD performance. This article addresses these issues as they relate to technological innovativeness. The author reports the results of a research study designed to (1) assess the direct contributions of design integration and top management support to several dimensions of NPD performance, and (2) identify potential moderating influences of technological innovativeness on these direct effects. A survey of 136 NPD projects drawn from firms representing most of the major U.S. manufacturing industries provides data for the study. The overall goals of the study were to amplify our understanding of management's role in NPD and to further the development of contingency theory explaining new product success. The results indicate that design integration is positively associated with higher design quality in NPD, but it is not significantly linked with better financial performance. In addition, design integration appears to be an important influence on achieving NPD time goals, but only in cases of high technological innovativeness. This result suggests that increased design integration produces its greatest impacts when development processes are full of uncertainty. Top management support is positively associated with better time-based performance, design quality, and financial performance on the whole. However, a significant interaction effect suggests that high levels of top management support are ineffective in securing good financial performance in high technologically innovative environments. Other forces appear to be at work in these circumstances, making top management support less important. The article discusses the implications of these findings for management practice, a contingency-oriented view of NPD processes, and future research. [source] Local Knowledge as Trapped Knowledge: Intellectual Property, Culture, Power and PoliticsTHE JOURNAL OF WORLD INTELLECTUAL PROPERTY, Issue 1 2008Chidi Oguamanam Discourses of local knowledge and categories of rights claimants thereto are embroiled in complex conceptual and analytical morass. The conceptual quandary around local knowledge is diversionary from the historically rooted hierarchies of culture, power and politics that have subjugated it. Claims to local knowledge are challenged from several dimensions, including arguments from cultural cosmopolitanism, intellectual property rights and aspects of liberal democratic principles. An interesting new site for this power play is the emergent bioprospecting framework of access and benefit sharing. In this context, sophisticated external intermediaries, who have asymmetrical power relationships with custodians of local knowledge, now constitute a new threat to the genuine aspirations of indigenous and local communities. Recently, local knowledge claims are conflated with propertization of culture raising concerns over the asphyxiation of the public domain. Making the claims or claimants to local knowledge the scapegoats of our troubled public domain undermines the source of the problem. In a way, the current anemic state of our public domain can be blamed on unwholesome expansion of intellectual property and unidirectional appropriation of local knowledge by external interests. The reality of cultural cosmopolitanism requires an intellectual property order that is responsive to the contributions of local knowledge. [source] THE SOCIAL EFFICIENCY OF INSTRUMENTS FOR THE PROMOTION OF RENEWABLE ENERGIES IN THE LIBERALISED POWER INDUSTRYANNALS OF PUBLIC AND COOPERATIVE ECONOMICS, Issue 3 2006Dominique Finon ABSTRACT,:,This paper compares the social efficiency of the two main regulatory instruments used to promote renewable energy sources in electricity generation (RES-E), taking into consideration their role in promoting the preservation of the climate. They are based on a purchase obligation and act either by price (feed-in tariffs) or by quantity (RES-E quotas). In their reference design, the instruments show different performances in several dimensions: market incentives intensity, control of the cost for consumers, safeguards of RES-E investments, and conformity with the new market regime of the electricity industry. The comparison shows that neither instrument offers an optimal solution in each of these dimensions. In particular, the intrinsic qualities of the quotas instrument that are put forward to mandate its adoption by the EU members are overestimated. A government will thus select an instrument in accordance with the relative importance of its objectives: environmental policy versus cost control by market pressure. [source] The relationship between attention deficit hyperactivity disorder, conduct disorder, and psychopathy in adolescent male and female detaineesBEHAVIORAL SCIENCES & THE LAW, Issue 4 2009Kathrin Sevecke M.D. Although ADHD and CD are apparent risk factors for adult psychopathy, there are three distinct perspectives regarding their relationships to psychopathy: (1) ADHD may contribute uniquely to the development of psychopathy or (2) its contribution may reflect its high comorbidity with CD. Alternatively, (3) the comorbid presence of ADHD and CD may confer unique risk for the development of psychopathy. Although prior adult studies have yielded conflicting findings, no prior studies of adolescents address this issue. We examined these three hypotheses and the possibility of sex differences using cross-sectional analyses in 90 male and 123 female incarcerated adolescents. Among males the influence of ADHD was largely attributable to the overlap between ADHD and CD, whereas among females ADHD contributed independently to psychopathy scores and to scores on several dimensions of psychopathy. In addition, among females, the ADHD,×,CD interaction was significant for the total score and the antisocial component of psychopathy and in a direction opposite to that predicted by the comorbid subtype hypothesis. These findings indicate that there may be sex-specific pathways to elevations in psychopathic traits and suggest that the comorbid subtype hypothesis is probably not correct for either boys or girls.
