Selon Hoffman & Novak (2018), les objets connectés grand public qui ouvrent la voie à de nouvelles expériences d'usage, ont le potentiel de révolutionner la vie des consommateurs dans les années à venir. Le principal enjeu des objets connectés réside dans le fait d'intégrer leur usage dans les pratiques quotidiennes des consommateurs en produisant activement des données d'usage sur le long terme, à savoir l'appropriation. Cette recherche a validé le modèle explicatif de l'appropriation de l'objet connecté grand public au travers des besoins psychologiques des consommateurs français à l'égard de leurs objets connectés possédés. Nos résultats montrent que l'appropriation de l'objet connecté est fortement corrélée au besoin d'identité de soi, le besoin d'avoir un territoire ainsi que le besoin d'efficace et d'effectance. Et l'appropriation de l'objet connecté peut avoir un impact positif sur la perception de la valeur globale de l'objet connecté par les consommateurs, les comportements extra-rôle des consommateurs, ainsi que la satisfaction de leur vie quotidienne. Par ailleurs, le rôle médiateur des comportements extra rôle dans la relation entre l'appropriation et la valeur perçue nous permet d'affiner la compréhension des mécanismes de cocréation de valeur du point de vue du consommateur. Il nous enseigne de manière complémentaire comment l'appropriation de l'objet connecté contribue à la création de valeur par les consommateurs. / According to Hoffman & Novak (2018), the smart connected object is presenting new opportunities for usage experience that have the potential to revolutionize consumers' lives. The main challenge for smart connected objects is to integrate their use into the daily practices of consumers by actively producing usage data in the long-term, namely appropriation. This research has validated the explanatory model of consumer smart connected object appropriation through the psychological needs of French consumers regarding their smart connected objects. Our results show that the smart connected object appropriation is strongly correlated with the need for self-identity, the need for having a place, the need for efficacy and effectance. And the smart connected object appropriation has a positive impact on perceived value of smart connected objects by consumers, their extra-role behaviors, as well as satisfaction of their daily life. Moreover, the mediating role of extra-role behaviors in the relationship between appropriation and perceived value allows us to understand in a complementary way the value cocreation mechanisms from the viewpoint of consumers, concerning how the smart connected object appropriation contributes to value creation by consumers.

This study assessed how Constructivist theory accounts for verbal dominance. Conversations of rotating dyads were tape recorded, then coded for measures of dominance. Subjects completed a trait dominance scale and a constructivist personality test. Interpersonal rankings of dominance were found to be more consistent with observed behavior than trait dominance scores. Extreme trait dominance scores were associated with a constructivist measure indicating maladjustment. Dyads identified as more resistant to change were found to use fewer verbal control strategies; male/male dyads were characterized by direct, functional interactions. Dyads that were highly comfortable with one another utilized fewer verbal control methods. Lastly, interactions in which participants reported unfamiliar self-experiencing utilized higher levels of verbal control. Implications for group processing, assessment of dominance and sex differences are discussed.

The purpose of this study was to examine cognitive complexity, extremity, and the relationship between social repertory grids and life events repertory grids (LERG) in people who report a history of trauma. Effects of type of trauma on complexity and extremity scores of each type of grid were examined. Prior research into repertory grids and trauma has used only one type of grid, predominantly social grids or LERGs. Therefore, a natural, progressive step in the grid research involved investigating how individuals integrate social and life event constructs. It was hypothesized, and results show, that there is a positive correlation between complexity scores and extremity scores of social grids and LERGs. However it was not found that there was a negative correlation between trauma history and complexity scores, and that trauma acts as a moderator for cognitive complexity. Instead, it appears that the social facet of experience is key to understanding perception of traumatic experiences. Additionally, number of traumas experienced might affect social construct elaboration.

The Adolescent Discouragement Indicator (ADI) was developed to assess the Adlerian construct of discouragement. The 75-item ADI contains five subscales corresponding to the five life tasks specified in Individual Psychology and is specifically designed to pinpoint the area and degree of adolescent discouragement. Item selection was based on ratings by five prominent Adlerians and item correlation with subscale scores. Age and sex norms for the ADI were established on 225 females and 299 males 12 to 18 years of age. Findings indicate that female adolescents are less discouraged than male adolescents on all scales except the love scale and both sexes reported the least amount of discouragment on the love scale. The only significant difference among the age groups is between the 13-year-olds and the 15, 16, and 17-year-olds on the love scale. An internal consistency coefficient of .95, a 2-week test-retest coefficient of .89, and a 4-week test-retest coefficient of .92 indicates that the ADI is a reliable instrument. Negative and significant (p < .001) correlations between the ADI and Social Interest Index (Greever, Tseng, & Friedland, 1973) and between the ADI and the Social Interest Scale (Crandall, 1975) contribute to construct validity and support Adler's belief that discouragement and social interest are inversely related. Results of behavioral and academic comparisons on a sample of adolescent males (N=57) seem to indicate a link between behavior, academic performance, and levels of discouragement. Results of factor analysis and interscale correlations are presented. Implications for further research include continued validation using behavioral criteria associated with discouragement, refinement of the subscales and establishment of score ranges to indicate when an adolescent is considered discouraged.

The Rosenberg Self-Esteem Scale (RSES) has been the subject of widespread debate over the years. Initially conceptualised by Rosenberg as a undimensional measure of global self-esteem, other studies have found evidence that challenges this notion, suggesting that this scale is in fact a multidimensional measure. The aim of this study was to investigate the construct validity of the RSES among South African university students. The RSES was administered to students from two different South African universities located in different regions (N = 304). Principal component analysis (PCA) was used in order to investigate the factor structure of the RSES and correlations were run between the RSES and the General Self-Efficacy Scale (SGSES) to investigate the relationship between self-esteem and self-efficacy. The PCA findings yielded a single factor structure of the RSES in the South African university student sample and a significant positive correlation was observed between self-esteem and self-efficacy. The findings therefore supported the construct validity of the RSES within the South African university context. / Mini Dissertation (MA)--University of Pretoria, 2017. / Psychology / MA / Unrestricted

Background: Unaccompanied refugee minors (URM) report increased levels of mental health problems, specifically symptoms of post-traumatic stress disorder (PTSD) are very common. They have often experienced multiple trauma events and additional stressors related to migration, acculturation and family separation. High-quality measurements of PTSD symptoms that are brief and easy to administer among URM are therefore needed. Aims: The aim of this study was to evaluate the psychometric properties of the Children’s Revised Impact of Events Scale (CRIES-8) when used in a population of URM. Method: Confirmatory factor analyses, internal consistency and test-retest agreement were analyzed using data from two previous studies; one Norwegian longitudinal study of URM mental health including 284 participants and 104 participants from a Swedish intervention study. Results: CRIES-8 in this population showed questionable levels of internal consistency and moderate test-retest agreement. The two-factor model of Intrusion and Avoidance was confirmed to have god model fit in this study, while the one-factor model of PTSD had poor model fit. Three items related to Avoidance (2,5 &amp; 8) were found to have a large proportion of error in the one factor model. Conclusion: When CRIES-8 are used in studies of PTSD among URM the reliability and validity seems lower than previously found in other contexts. Especially the items related to avoidance seem potentially problematic in this context. It is recommended that researchers and clinicians are cautious when interpreting CRIES-8 scores when used with URM.

5 Abstract This thesis deals with topic concerning photography and its relation to reality in work of French philosopher and art historian Georges Didi-Huberman. The thesis is divided into two main chapters. The first main part includes introduction to Didi- Huberman's approach and familiarization with his terms as well as theoretical analysis of photography through his work. This part also includes comparison with approach of the other authors, for example with Roland Barthes. The goal of this thesis is to identify possible ways thinking about photography, from the perspective of photography as a construct and photography as a testimony. The goal of the second main part is to use Didi-Huberman's approach and apply it on several selected photographies within contemporary context. Key Words Didi-Huberman, photograph, construction, testimony, surviving images

The purpose of the present investigation was to investigate the relationship of cognitive complexity, as measured by a quantitative index of human movement responses, and the number of different constructs in one psychological system.

Background and Aim: Although inroads are currently being made into research in the area of organisational energy, an exhaustive search of the literature has indicated that research into measurement instruments which are applicable in the South African context is scant, with two empirical studies having been conducted in South Africa on organisational energy (Derman, Barkhuizen, & Stanz, 2011; Lamberti, 2010). As there is minimal research into organisational energy measures which are most appropriate for use in the South African context, this study explores the reliability and validity of the Productive Energy Measure (PEM) (Bruch, Cole & Vogel, 2005) in the South African context. This study also adds to the existing knowledge on the Energy Scapes Profile (ESP) (Tosey & Llewellyn, 2002) in the South Africa. Method: A cross-sectional survey research design is followed with data being collected from employees (N=303) from South African institutions. The ESP (Tosey & Llewellyn, 2002), and the PEM (Cole, Bruch & Vogel, 2011) are administered. Exploratory Factor Analysis, Confirmatory Factor Analysis, construct equivalence item bias analyses, Analysis of Variance, Multivariate Analysis of Variance and Regression Analysis are applied. Results:  Confirmatory factor analysis (CFA) of the ESP reveals that both a seven-factor and a one-factor model were inconclusive. Subsequent Exploratory factor analysis (EFA) reveals a one-factor structure. The theoretical sub-scales of the ESP show a high level of internal consistency.  The results of the CFA for the PEM clearly reveal a three-factor model. The three theoretical sub-scales show an excellent level of reliability. Statistically significant differences are found in the productive organisational energy levels of employees based on job level, home language, years in current job and the PEM dimensions.  Results of the regression analysis indicate that a statistically significant relationship exists between organisational energy and productive organisational energy. Practical Relevance: As far as could be determined, this is the first study to make use of the PEM in South Africa. The study attempts to identify which measure of organisational energy is most appropriate for use in the South African context, and makes a contribution to the body of knowledge surrounding organisational energy measurement instruments in the South African context. Furthermore, the study of measures of organisational energy which can be applied in the South African context provides assistance to those interested in measuring organisational energy in the workplace. / Dissertation (MCom)--University of Pretoria, 2011. / Human Resource Management / Unrestricted

This study explores how victims of violent crime construct meaning around crime, justice and reconciliation. It further aims to gain insight into how victims of crime construct expectations of which actions should ensue after the crime and whether their constructions encompass elements of reconciliation and restorative justice. The study is conducted from a social constructionist position and uses a critical discourse analysis framework in analysing the data. In-depth interviews were conducted with nine victims of serious crimes such as armed robbery, hi-jacking, attempted murder and rape. From the analysis it appears that participants have a need to experience justice and have a high demand for vengeance. This however may itself have grown out of a lack of a more positive experience of justice. Participants’ constructions of their experience of being a victim of crime center on notions of power, equality, prejudice and dominance. They draw on socially constructed differences based on race and gender to define both their identity as a victim of crime as well as the identity of their offender. These distinctions, based on categories of identity, serve to create an oppositional construction of “us” against “them” and also serve to dehumanise the offender. The analysis further indicates that participants draw on multiple constructions of restorative justice and despite strong support for punitive beliefs it appears that a discourse of restorative justice is also present in participants’ discussions. A key theme running through the data is the loss of personal power as a result of victimization. Instead of returning a sense of power to participants by allowing them to participate in the justice process, the legal system becomes the holder of the power and compounds the injury against the victim. The study has implications for how victims of crime are positioned in the justice system and how notions of restorative justice can be advanced in South African discourses.
