The main aim of this thesis was to examine internal representation in the context of nurse education using two main output variables - namely imagery and identity. The initial basic argument for the thesis was that procedures to facilitate the acquisition of psychomotor skills that have been developed in sports science could fruitfully be applied to the development of skills in other areas, such as nurse education. Study one approached this through the use of an imagery training programme - PETTIER (Holmes & Collins, 2001) on an undergraduate nursing curriculum. PETTIER served as the independent variable with the dependent variable - performance - being measured through Obje&tive Structured Clinical Examinations (OSCEs). Unexpected results revealed no significant differences between the control and experimental groups, with the control group actually performing better overall. Given this, the explicit choice was made to pursue investigation into the other plausible factors affecting behaviour, in order to explicate and underpin the results obtained. Study two investigated students' perceptions of and preparation for the OSCEs using a skills training questionnaire. Results revealed common concerns, specifically related to skills practice. Furthermore these concerned the amount of practice time provided; the practice environment; and the amount of support and training during teaching. In light of these findings, study three pursued a contrasting and comparative investigation from the professionals' perspective on the curriculum. This specifically examined perceptions of the assessment structure and expectations within the curriculum; the content of the curriculum; levels of support and provision for training; and the application of theory and practice. This aimed to identify any coherent or conflicting views between the students' receiving the curriculum and the staff delivering the curriculum. Results revealed coherency in the professional view that theory and practice were equally as important for nurse education. However, students commonly perceived practice as the most important aspect. Also, some students often struggled to apply theory to practice and vice versa. In light of this it became apparent that students may in fact identify differently with the content of the curriculum. Therefore, appraisal of the content may have different significance for students and affect behaviour differently both internally and/or externally. Study four investigated this using Identity Structure Analysis (ISA)/lpseus (Weinreich & Saunderson, 2003).This explored how students applied themselves to the various aspects of nursing in the contexts of healthcare and broader affiliations, and how these fitted into students' broader sense of identity. It also looked at typologies within nursing and whether identity fitted into three distinct categories depending on construals. Study five followed this up using two individual case studies. The purpose of this was to encapsulate meaning behind individual construals and typologies and explicate the findings of ISA/lpseus and the implications for nurse education. Results found that construals are grounded in experiences which can affect development, behaviour and identity towards nursing and the broader affiliations in individuals' lives. In conclusion identity in nursing should be investigated further in order to provide stronger evidence in regards to typologies and how these may be influencing students' behaviour and development in nurse education. Such research could have important implications for the future of nurse education and be a positive step towards future curriculum revisions.

Future computer processors may have tens or hundreds of cores, increasing the need for efficient parallel programming models. The nature of multicore processors will present applications with the challenge of diversity: a variety of operating environments, architectures, and data will be available and the compiler will have no foreknowledge of the environment until run time. Adaptive Online Parallelization (ADOPAR) is a unifying framework that attempts to overcome diver sity by separating discovery and packaging of parallelism. Scheduling for execution may then occur at run time when diversity may best be resolved. This work presents a compact representation of parallelism based on the task graph programming model, tailored especially for ADOPAR and for regular and irregular parallel computations. Task graphs can be unmanageably large for fine-grained parallelism. Rather than representing each task individually, similar tasks are grouped into task descriptors. From these, a task descriptor graph, with relationship descriptors forming the edges of the graph, may be represented. While even highly irregular computations often have structure, previous representations have chosen to restrict what can be easily represented, thus limiting full exploitation by the back end. Therefore, in this work, task and relationship descriptors have been endowed with instantiation functions (methods of descriptors that act as factories) so the front end may have a full range of expression when describing the task graph. The representation uses descriptors to express a full range of regular and irregular computations in a very flexible and compact manner. The representation also allows for dynamic optimization and transformation, which assists ADOPAR in its goal of overcoming various forms of diversity. We have successfully implemented this representation using new compiler intrinsics, allow ADOPAR schedulers to operate on the described task graph for parallel execution, and demonstrate the low code size overhead and the necessity for native schedulers.

Le but de l’expérience décrite dans ce mémoire est d'arriver à inculquer inconsciemment aux sujets une stratégie visuelle leur permettant d'utiliser seulement une partie spécifique de l'information visuelle disponible dans le visage humain pour en reconnaître le genre. Normalement, le genre d’un visage est reconnu au moyen de certaines régions, comme la bouche et les yeux (Dupuis-Roy, Fortin, Fiset et Gosselin, 2009). La tâche accomplie par les sujets permettait un apprentissage perceptuel implicite qui se faisait par conditionnement opérant. Ces derniers étaient informés qu'un nombre de points leur serait attribué selon leur performance à la tâche. Au terme de l’entraînement, les sujets renforcés pour l’utilisation de l’oeil gauche utilisaient davantage l’oeil gauche que l’oeil droit et ceux renforcés pour l’utilisation de l’oeil droit utilisaient davantage l’oeil droit. Nous discuterons de potentielles applications cliniques de cette procédure de conditionnement. / The goal of the following experiment is to make subjects unconsciously learn a visual strategy allowing them to use only part of the available visual information from the human face to correctly identify the gender of a face. Normally, the gender of a face is recognized using certain regions, like those of the mouth and the eyes (Dupuis-Roy, Fortin, Fiset et Gosselin, 2009). Our participants had to accomplish an operant conditionning task. They were informed that a number of points would be given to them according to their performance. At the end of training, the subjects that were encouraged to use the left eye indeed used the left eye more than the right. Also, those that were conditionned to use the right eye used the right eye more than the left. We will discuss the potential clinical applications of this method of conditionning.

Title: Artificial Neural Networks and Their Usage For Knowledge Extraction Author: RNDr. Zuzana Petříčková Department: Department of Theoretical Computer Science and Mathema- tical Logic Supervisor: doc. RNDr. Iveta Mrázová, CSc., Department of Theoretical Computer Science and Mathematical Logic Abstract: The model of multi/layered feed/forward neural networks is well known for its ability to generalize well and to find complex non/linear dependencies in the data. On the other hand, it tends to create complex internal structures, especially for large data sets. Efficient solutions to demanding tasks currently dealt with require fast training, adequate generalization and a transparent and simple network structure. In this thesis, we propose a general framework for training of BP/networks. It is based on the fast and robust scaled conjugate gradient technique. This classical training algorithm is enhanced with analytical or approximative sensitivity inhibition during training and enforcement of a transparent in- ternal knowledge representation. Redundant hidden and input neurons are pruned based on internal representation and sensitivity analysis. The performance of the developed framework has been tested on various types of data with promising results. The framework provides a fast training algorithm,...

Cette recherche a été inspirée par les travaux de John Bowlby sur l’attachement ainsi que par les écrits psychanalytiques de Sigmund Freud et de Donald Winnicott sur le développement de la relation père-garçon. Trois objectifs ont été formulés dans la présente étude : A) Les jeunes garçons d’âge préscolaire pourraient-ils projeter, à travers quelques sessions de jeu symbolique libre, leurs représentations paternelles? B) S’ils les projettent, quelle est la nature de ces représentations paternelles? C) Existe-t-il une relation entre le type d’attachement (évalué par un instrument standard) et les représentations paternelles projetées dans le jeu symbolique libre? Dix garçons de quatre ans ont été filmés à la maison et dans une garderie pendant, en moyenne, quatre sessions totalisant par enfant, une durée moyenne de deux heures trente minutes de jeu symbolique. Le type d’attachement a été évalué à l’aide de l’Attachment Story Completion Task. Les résultats démontrent que l’ensemble des garçons ont été en mesure de projeter des représentations paternelles basées sur la figure du père. Tous ces garçons ont perçu le père comme une figure de protection et huit enfants sur dix ont exprimé verbalement leur attachement à ce dernier. Un enfant de type évitant (type A) n’a pas évoqué la figure du père dans son jeu. Ce père était rarement à la maison pour s’occuper de son garçon. Enfin, le dernier enfant, de type ambivalent (un enfant particulièrement agressif de type C), a présenté dans son jeu des interactions négatives avec le père et ce, tout au long des sessions de jeu symbolique. Il appert ainsi que le jeu symbolique permet à l’enfant de projeter des représentations de la figure paternelle. Ces représentations sont en lien avec le type d’attachement que l’enfant détient au moment de l’évaluation. / This research was inspired by the work of John Bowlby on infant attachment and the psychoanalytic writings of Freud and Winnicott on the father figure. Three objectives were formulated for this exploratory study; a) Will the young preschool boy spontaneously project his paternal representations in the context of a series of symbolic free play sessions? b) If so, what is the nature of the paternal representations? c) Is there a relationship between the type of attachment as evaluated with a standardized instrument and the paternal representation projected into the free play sessions? Ten four year old boys were filmed in their own homes and in the daycare setting during an average of four sessions each for a total of two and a half hours. The type of attachment was evaluated with the Attachment Story Completion Task. The results showed that all of the boys were capable of projecting paternal representations onto the father figures. All of the children perceived these figures as a source of protection and eight out of ten verbally expressed their attachment to them. One insecure boy (type A) did not invoke the father figure in his play and in real life his father was rarely at home. The remaining insecure boy (a very angry type C) showed consistent negative interaction with the father figure throughout the sessions. It seems that the symbolic play allow the child to project adequatly the representation of the father figure. These representations are linked to the attachment type that the children possessed at the moment of the evaluation.
