The problem of this study was to test the differences between adult children from alcoholic families with adult children from non-alcoholic families on levels of depression, self-esteem, and anxiety. The sample consisted of 203 volunteers, all from the Counselor Education Department, 150 females and 53 males, ages 19 and older. Volunteers who were noted as being adult children of alcoholic families numbered 60. Measures used were the Children of Alcoholics Screening Test (CAST), the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), and the Coopersmith Adult Self-Esteem Inventory (SEI). Multivariate Analysis of Variance was used to test for differences between groups. In addition, a secondary analysis using a one-way MANOVA was used to test for differences between dysfunctional and functional family of origin status on the dependent variables of depression, self-esteem, and anxiety.

Dans leurs processus d’innovation, les grandes entreprises subissent un manque de ressources entre Recherche et Développement appelé vallée de la mort. Le groupe Safran s’est doté d’une direction de l’innovation afin de le compenser. Son fonctionnement est fondé sur une logique d'échange avec les sociétés du groupe. Mais dans les phases amont, lorsque les échanges comportent des inconnus, ils s’interrompent brutalement. En particulier des fiches idées issues de DKCP ne sont pas explorées. Cette recherche-intervention ambitionne donc d’établir un modèle d’action collective pour échanger dans l’inconnu. Elle défend la thèse que dans l’inconnu, vendeurs et acheteurs de technologies innovantes s’engagent dans la conception de la frontière entre des technologies et des environnements.Face aux limites des modèles d’échange marchand, de décision, d’intéressement et de créativité, cette thèse adopte un modèle d’échange intégrant l’inconnu et un cadre analytique issu des théories de la conception innovante. Elle propose le modèle de l’engagement conceptif de ressources. Elle explicite les limites de l'outil conventionnel d'échange de technologies dit Technology Readiness Levels adopté chez Safran. Elle propose alors de modéliser les échanges entre vendeurs et acheteurs de technologies comme l’exploration de la frontière Technologie-Environnement en suivant le formalisme C-K T / C-K E construit. Finalement la méthode Pilotage de l'Exploration Par les Invariants Technologie-Environnement (PEPITE) est élaborée avec la direction de l'innovation Safran sur la base de deux cas d’exploration ayant effectivement passé la vallée de la mort durant l’intervention des chercheurs. / Innovation processes of large companies experience a lack of resources between Research and Development, i.e. the valley of death. Safran created its Innovation Department to counterbalance. It is based on exchanges with the subsidiaries. However such exchanges cannot be processed in most early stages, when they include unknowns. For instance, ideas generated through the DKCP method remain unexplored. This intervention-research aims at establishing a model of collective action to exchange in the unknown. It defends the thesis that, in the unknown, sellers and buyers of innovative technologies engage in the design of the boundary between technologies and environments.Facing the limits of classic models of exchanges of economy, decision, intéressement and creativity, this thesis adopts a design-theories framework. It proposes the model of design engagement of resources. It explains the limits of a common tool for exchanging technologies, i.e. Technology Readiness Levels. It proposes to model exchanges between seller and buyer as the exploration of the Technology-Environment boundary. To do so it constructs the C-K T / C-K E formalism. Finally, the method Steering Exploration Through Technology and Environment Invariants ("Pilotage de l'Exploration Par les Invariants Technologie-Environnement" (PEPITE) in French) is constructed in collaboration with Safran Innovation Department. It is based on two cases of explorations which passed the valley of death within the researchers intervention.

This study investigated Black, White, and Indian South African university students' lay theories of intelligence. 260 students participated in this study, with an age range of 18 - 39 years. The study, which is based on the theory of multiple intelligences, explored everyday perceptions of intelligence across race groups in a South African setting. The independent variables of interest were race/culture and gender, while overall and multiple intelligences served as dependent variables. Participants were asked to rate their own overall (general) as well as multiple intelligences. They were then asked to rate the overall as well as multiple intelligences of in-group (same race) and out-group (different race) members of both genders. There was a statistically significant race effect, with White and Indian students giving Black students lower ratings and Black students in turn giving White and Indian students lower ratings. This may be a result of historically racialized discourses that still influence everyday perceptions of the 'Other'. There was a statistically significant gender effect with females giving higher estimates to not only themselves, but also to mates as well for all the multiple intelligences. It can be postulated that this may be a consequence of a population that has been sensitized to gender stereotyping, in addition to educational institutions promoting female friendly policies. / Thesis (M.Soc.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

It sometimes happens that we finish reading a passage of text just to realize that we have no idea what we just read. During these episodes of mindless reading our mind is elsewhere yet the eyes still move across the text. The phenomenon of mindless reading is common and seems to be widely recognized in lay psychology. However, the scientific investigation of mindless reading has long been underdeveloped. Recent progress in research on mindless reading has been based on self-report measures and on treating it as an all-or-none phenomenon (dichotomy-hypothesis). Here, we introduce the levels-of-inattention hypothesis proposing that mindless reading is graded and occurs at different levels of cognitive processing. Moreover, we introduce two new behavioral paradigms to study mindless reading at different levels in the eye-tracking laboratory. First (Chapter 2), we introduce shuffled text reading as a paradigm to approximate states of weak mindless reading experimentally and compare it to reading of normal text. Results from statistical analyses of eye movements that subjects perform in this task qualitatively support the ‘mindless’ hypothesis that cognitive influences on eye movements are reduced and the ‘foveal load’ hypothesis that the response of the zoom lens of attention to local text difficulty is enhanced when reading shuffled text. We introduce and validate an advanced version of the SWIFT model (SWIFT 3) incorporating the zoom lens of attention (Chapter 3) and use it to explain eye movements during shuffled text reading. Simulations of the SWIFT 3 model provide fully quantitative support for the ‘mindless’ and the ‘foveal load’ hypothesis. They moreover demonstrate that the zoom lens is an important concept to explain eye movements across reading and mindless reading tasks. Second (Chapter 4), we introduce the sustained attention to stimulus task (SAST) to catch episodes when external attention spontaneously lapses (i.e., attentional decoupling or mind wandering) via the overlooking of errors in the text and via signal detection analyses of error detection. Analyses of eye movements in the SAST revealed reduced influences from cognitive text processing during mindless reading. Based on these findings, we demonstrate that it is possible to predict states of mindless reading from eye movement recordings online. That cognition is not always needed to move the eyes supports autonomous mechanisms for saccade initiation. Results from analyses of error detection and eye movements provide support to our levels-of-inattention hypothesis that errors at different levels of the text assess different levels of decoupling. Analyses of pupil size in the SAST (Chapter 5) provide further support to the levels of inattention hypothesis and to the decoupling hypothesis that off-line thought is a distinct mode of cognitive functioning that demands cognitive resources and is associated with deep levels of decoupling. The present work demonstrates that the elusive phenomenon of mindless reading can be vigorously investigated in the cognitive laboratory and further incorporated in the theoretical framework of cognitive science. / Beim Lesen passiert es manchmal dass wir zum Ende einer Textpassage gelangen und dabei plötzlich bemerken dass wir keinerlei Erinnerung daran haben was wir soeben gelesen haben. In solchen Momenten von gedankenverlorenem Lesen ist unser Geist abwesend, aber die Augen bewegen sich dennoch über den Text. Das Phänomen des gedankenverlorenen Lesens ist weit verbreitet und scheint in der Laienpsychologie allgemein anerkannt zu sein. Die wissenschaftliche Untersuchung von gedankenverlorenem Lesen war jedoch lange Zeit unzureichend entwickelt. Neuerer Forschungsfortschritt basierte darauf gedankenverlorenes Lesen durch Selbstberichte zu untersuchen und als ein Phänomen zu behandeln das entweder ganz oder gar nicht auftritt (Dichotomie-Hypothese). Hier stellen wir die ‚Stufen der Unaufmerksamkeit’-Hypothese auf, dass gedankenverlorenes Lesen ein graduelles Phänomen ist, das auf verschiedenen kognitiven Verarbeitungsstufen entsteht. Wir stellen zudem zwei neue Verhaltensparadigmen vor um verschiedene Stufen von gedankenverlorenem Lesen im Augenbewegungslabor zu untersuchen. Als erstes (in Kapitel 2) stellen wir das Lesen von verwürfeltem Text vor als ein Paradigma um Zustände von schwach gedankenverlorenem Lesen experimentell anzunähern, und vergleichen es mit dem Lesen von normalem Text. Die Ergebnisse von statistischen Augenbewegungsanalysen unterstützen qualitativ die ‚Unaufmerksamkeits’-Hypothese, dass kognitive Einflüsse auf Augenbewegungen beim Lesen von verwürfeltem Text reduziert ist, und die ‚Foveale Beanspruchungs’-Hypothese, dass die Reaktion der zoom lens visueller Aufmerksamkeit auf lokale Textschwierigkeit beim Lesen von verwürfeltem Text verstärkt ist. Wir stellen eine weiterentwickelte Version des SWIFT Modells (SWIFT 3) vor, welches die zoom lens der Aufmerksamkeit implementiert, und validieren dieses Modell am Lesen von verwürfeltem und normalem Text (Kapitel 3). Simulationen des SWIFT 3 Modells unterstützen die ‚Unaufmerksamkeits’ und die ‚Foveal Beanspruchungs’-Hypothese in einem vollständig quantitativen Modell. Zudem zeigen sie, dass die zoom lens der Aufmerksamkeit ein wichtiges Konzept ist um Augenbewegungen in Aufgaben zum Lesen und gedankenverlorenen Lesen zu erklären. Als zweites (Kapitel 4) stellen wir den sustained attention to stimulus task (SAST) vor um Episoden von spontaner externer Unaufmerksamkeit (also Entkopplung der Aufmerksamkeit oder Abschweifen der Gedanken) in einem Paradigma über Verhaltensparameter wie das Übersehen von Fehlern im Text und Signal-Detektions-Analysen von Fehlerentdeckung zu messen. Augenbewegungsanalysen im SAST decken abgeschwächte Einflüsse von kognitiver Textverarbeitung während gedankenverlorenem Lesen auf. Basierend auf diesen Befunden zeigen wir, dass es möglich ist Zustände von gedankenverlorenem Lesen online, also während dem Lesen, aus Augenbewegungen vorherzusagen bzw. abzulesen. Dass höhere Kognition nicht immer notwendig ist um die Augen zu bewegen unterstützt zudem autonome Mechanismen der Sakkadeninitiierung. Ergebnisse aus Analysen von Fehlerdetektion und Augenbewegungen unterstützen unsere ‚Stufen der Unaufmerksamkeit’-Hypothese, dass Fehler auf verschiedenen Textebenen verschiedene Stufen von Entkopplung messen. Analysen der Pupillengröße im SAST (Kapitel 5) bieten weitere Unterstützung für die ‚Stufen der Unaufmerksamkeit’-Hypothese, sowie für die Entkopplungs-Hypothese, dass abschweifende Gedanken eine abgegrenzte kognitiver Funktionsweise darstellen, welche kognitive Ressourcen benötigt und mit tiefen Stufen von Unaufmerksamkeit zusammenhängt. Die aktuelle Arbeit zeigt, dass das flüchtige Phänomen des gedankenverlorenen Lesens im kognitiven Labor mit strengen Methoden untersucht und weitergehend in den theoretischen Rahmen der Kognitionswissenschaft eingefügt werden kann.

Purpose of the thesis This study aims to propose an AI maturity model in order to be able to evaluate to whatextent large-scale manufacturing companies utilize AI in their inbound logistical operationsand also to reveal the challenges related to the implementation of AI.  Methodology This study employs a qualitative research method with the use of a survey conducted on 10companies within 5 industries. Additionally, semi-structured interviews were employed attwo out of these 10 companies. Theoretical framework The theoretical framework provides a deeper theoretical understanding of inbound logisticsoperations, AI implementations and their suggested operationalization in inbound logisticsoperations at large-scale manufacturers. Further, it also provides theory of the challengesassociated with implementing AI in inbound logistics operations. Empirical data The empirical section illustrates the data that were collected through survey and interviewstudy. First, data is presented based on the respondents' various industries that are grouped.Within each grouped industry, data is structured according to the various RQ’s and proposedframeworks, meaning that data will be related to the different levels of AI implementation,maturity levels as well as challenges. Analysis and discussion In this section, the industries are analysed and discussed with the help of the theoreticalframework and collected empirical data. This was first established with an individual analysisof industries where one research question is covered at a time. After this is done, across-analysis is carried out on the involved industries in relation to the research questions. Conclusion This chapter gives a concluding discussion and presents theoretical and practicalcontributions. The main results of the three research questions are highlighted. Finally, further research opportunities and limitations are discussed.
