An Assessment of Paired Similarities and Card Sorting

Dwyer, Theodore James 12 November 2003 (has links)
Alcohol expectancies have been shown to be predictive of risk for alcohol problems. Experimental research studies have challenged participants' expectancies with the end result demonstrating a mediational effect on participant drinking. Cognitive research using priming and word recognition tasks have led to the theory that expectancies operate in an associative network. Using dissimilarities information this network has been mapped using multidimensional scaling. The current techniques for collecting dissimilarities information directly in alcohol expectancy research has been limited to the use of the paired comparisons tasks. In order to investigate the utility of a different similarities task a comparison was made between a card sorting task and paired comparisons. The overall comparisons of matrices and Individual Difference Scaling (INDSCAL; Carroll & Chang, 1970) results followed the expected trends and generally supported the hypotheses that the two methods would provide essentially the same information. However, a possible method effect for gender was observed. The method effect was seen when comparing across methods within the females dichotomized by drinker category. Further studies are necessary to replicate these findings and to attempt to identify which method has the effect.

Vad motiverar ungdomar till att börja idrotta och vad är det som hindrar dem? : en intervjustudie om skillnader och likheter mellan svenska ungdomar och invandrarungdomar

Jirevall, Emelie January 2009 (has links)
<p>Föreningsidrotten ökar men fortfarande är det många ungdomar som inte är tillräckligt fysiskt aktiva. Många undersökningar har gjorts angående motivation hos aktiva idrottare, men forskningen kring vad det är som motiverar ungdomar att börja idrotta är inte alls lika stor. Syftet med denna studie var att undersöka vilka motivationsfaktorer som skulle få ungdomar att börja idrotta och vad det är som hindrar dem, samt se vilka skillnader och likheter det fanns mellan svenska ungdomars och invandrarungdomars svar. Genom att undersöka vad som skulle få ungdomar att börja idrotta och vad det är som hindrar dem, skulle detta kunna hjälpa idrottsföreningar i hur de ska rekrytera nya medlemmar. Det är också viktigt att undersöka om det är någon skillnad mellan svenska ungdomars och invandrarungdomars motivationsfaktorer och hinder. Enskilda intervjuer gjordes med svenska ungdomar och invandrarungdomar från två olika skolor. Intervjuerna som spelades in på band transkriberades, för att sedan analyseras utifrån en hermeneutisk ansats. Teman i form av inre och yttre motivation, samt inre och yttre hinder togs fram, därefter skapades kategorier utifrån de motivationsfaktorer och hinder som var särskilt betydelsefulla för ungdomarna. Resultatet visade att de faktorer som skulle motivera ungdomarna att börja idrotta var socialt stöd, tidigare positiva erfarenheter av idrott, bättre hälsa, att det var roligt och att de hittade en idrott som passade dem. Det som hindrade dem var tidsbrist, låg grad av self-efficacy, prestationskrav, den sociala miljön, andra preferenser, att det inte var roligt och jobbigt idrotta, samt att de inte hade hittat någon passande idrott. Det kunde inte urskiljas några större skillnader mellan de svenska ungdomarna och invandrarungdomarna, men de svenska ungdomarna motiverades av både inre och yttre faktorer medan invandrarungdomarna endast motiverades av inre faktorer.</p>

Nio individer från Västra farleden : en osteologisk analys av nio individer från medeltida Västergarn, Gotland / Nine individuals from West channel : an osteological analysis of nine individuals from medieval Västergarn on Gotland

Karlsson, Alexandra January 2011 (has links)
Osteological examinations were executed on nine mediaeval individuals from Västergarn, Gotland, with the main aim to increase the knowledge about the people who lived there during the Middle Ages. A further aim was to compare the results from this study with other populations from the same time period, which in this case was the "Bonegathering" from Västergarn as well as previous osteological results from Sigtuna and Västerhus. Archaeological excavations have been occurring in Västergarn since 1971 and are still occurring in an educational purpose, for students of Gotland University. The age distribution of the individuals showed ages from 2 years old up to 44 years, with five adults and four children. The gender distribution show approximately five women and one man. A significant observation was made from the presence of caries and calculus, which can be observed in that some had more calculus then caries. Examples of the skeletal changes that occurred during the examinations was Schmorl`s noder, cribra orbitalia and inflammations. The comparison between other populations showed no obvious difference.

Semantic Decision Support for Information Fusion Applications

Bellenger, Amandine 03 June 2013 (has links) (PDF)
This thesis is part of the knowledge representation domain and modeling of uncertainty in a context of information fusion. The main idea is to use semantic tools and more specifically ontologies, not only to represent the general domain knowledge and observations, but also to represent the uncertainty that sources may introduce in their own observations. We propose to represent these uncertainties and semantic imprecision trough a metaontology (called DS-Ontology) based on the theory of belief functions. The contribution of this work focuses first on the definition of semantic inclusion and intersection operators for ontologies and on which relies the implementation of the theory of belief functions, and secondly on the development of a tool called FusionLab for merging semantic information within ontologies from the previous theorical development. These works have been applied within a European maritime surveillance project.

Value Similarities Of Wives And Husbands And Conflict Resolution Styles Of Spouses As Predictors Of Marital Adjustment

Ozen, Ayca 01 June 2006 (has links) (PDF)
The aim of this present study was to investigate the predictive power of value similarity of wives and husbands and conflict resolution of spouses on marital adjustment of wives, husbands, and couples. Data is collected by means of questionnaires (&ldquo / Schwartz&rsquo / s Value Survey&rdquo / , &ldquo / Dyadic Adjustment Scale&rdquo / , and &ldquo / Conflict Resolution Styles Scale&rdquo / ), from a sample of one hundred and forty (140 women, 140 men) Turkish married couples. The results of the study indicated that after eliminating the effects of demographic variables, tradition, hedonism, stimulation value type similarities of spouses, and power value type dissimilarities of spouses have positively predicted marital adjustment of wives and couples. However, value similarities of spouses did not have significant effect on marital adjustment of husbands. Although, conflict resolution styles of husbands had a significant effect on marital adjustment of wives, conflict resolution styles of wives did not have significant contribution in predicting marital adjustment of husbands after eliminating the effects of demographic variables and value similarity of spouses. The usage of negative conflict resolution styles by husbands had negative effects on marital adjustment of wives. When the marital adjustment of couples was considered, it was found that conflict resolution styles of wives and husbands have significant contribution in predicting marital adjustment of couples. The results further indicated that negative conflict resolution styles of wives and husbands negatively predicted marital adjustment of couples. Furthermore, it was found that spouses high in positive conflict resolution style and low in negative conflict resolution style have higher scores on marital adjustment than spouses low in positive conflict resolution style and high in negative conflict resolution style. The findings of the present study were discussed in the light of the related literature. Additionally, limitations of the study and suggestions for future researches were investigated.

Early family trauma: a comparison between adults with schizophrenia and depression

Littler, Susan E. January 2006 (has links)
[Abstract]: This study explores similarities and differences in the early family history of an adult group with schizophrenia, and a matched group with major depression. Attachment theory, trauma theory and their relation to serious mental illnesses are used to understand the clinical participants’ reported early traumatic experiences of emotional deprivation and neglect.A retrospective design includes self-report questionnaires from clinical participants, and semi-structured interviews with participants’ mothers/primary caregivers.Data analysis includes:1. Assessment of matched participants’ reported prevalence of emotional deprivation and neglect in four different age groups;2. Assessment of themes of early family trauma and sequelae from the mother interviews;3. Qualitative analysis of sample mother/primary caregiver interviews from each diagnostic group of the manner in which the interviewees construct their stories around trauma;4. Quantitative analysis of a conceptualised model representing the arguments developed in the body of this dissertation.The second and third forms of analysis above include a panel of three experts, blind to diagnosis, validating this researcher’s findings.Standard multiple regression analysis indicates participants’ reported neglect across all age groups significantly predicts emotional deprivation, with neglect contributing 27.4% of the variability, but with no individual age band contributing significantly to the equation.Themes from the mother interviews are clustered into three constructs, guided by the research questions and this researcher’s clinical experience, the mothers’ emphases and the expert panel into Early Family Trauma, Maternal Fatigue, and Clinical Participants’ Early Attachment Difficulties.The mothers’ manner of discussing early family trauma is defined via speech markers as dissociative (disorganised, incoherent, and unresolved) or coherent (grounded, sequential and resolved) according to Attachment Theory and the literature on dissociation. Speakers are assigned as using dissociation or not as a categorical variable.A model is conceptualised to represent the interrelatedness of data from the participants and their mothers, including the manner in which the mothers relate early family trauma. Canonical Discriminant Function Analysis indicates that early family trauma and maternal fatigue discriminate little between diagnostic groups and that maternal non-resolution of early traumatic events and (possibly related) participant offspring attachment difficulties contribute most to distinguishing between the two diagnostic groups. Finally, a greater number of participants from the schizophrenia sample than from the depression sample continue to live with mother, possibly indicating that the early attachment difficulties remain unresolved.Discussion offers a reconceptualisation of several major and/or established theories concerning risk factors in schizophrenia, and examines shortcomings in the literature, concluding with suggestions for future research.
