Timely student completion of undergraduate nursing programs in order to produce practicing registered nurses (RNs) is of concern to students, faculty, governments, employers, and health care consumers across Canada. The shortage of health care professionals in Saskatchewan, particularly in nursing, is an immediate and growing concern. The average age of RNs in Saskatchewan is 44.9 years (CIHI, 2003). With the inevitability of retirement of many RNs, recruitment and retention of new nurses is critical to the quality of health care in this province. The looming shortage creates a further challenge for key stakeholders in academia, government, and health regions who hold a vested interest in the retention of nurses educated in Saskatchewan. Currently, little is known about the impact of barriers to timely completion of students in the Nursing Education Program of Saskatchewan (NEPS). Considering the aging nursing workforce, frequent, substantial numbers of nursing graduates are important to meet the demand for health human resources in the province of Saskatchewan (SRNA, 2004). <p>The purpose of this research was to conduct a secondary analysis of the NEPS Database including exit surveys completed by 363 graduates over a three-year period, 2002-2003; 2003-2004; 2004-2005. Group membership was determined by splitting data between graduates who had taken four academic years (September to April) or less to complete the program (timely completers) and those who took longer than four academic years (delayed completers). Objectives were to examine the differences between the two aforementioned groups in terms of the following variables: employment hours, financial burden, student loan status, dollar amount of bursaries awarded during the NEPS, primary responsibility the year prior to the NEPS, significant life changes during the NEPS, Aboriginal ancestry and core course averages. <p>Results show that 86% of females in the study group completed the NEPS in a timely manner compared with 58% of their male counterparts. There was a trend of higher employment hours per week in every year of the NEPS for delayed completers. However, this difference approached statistical significance only for students in year one, t (360) = 1.81, p < .07. Fifty percent of delayed completers had three or more significant life changes during the NEPS. Seventy-five percent of timely completers had two or fewer significant life changes. Students require various forms of support to ensure timely completion of the NEPS. It is anticipated that results of this research will inform policy decisions to facilitate timely completion of the NEPS.

Enrollment in online courses has outpaced overall university enrollment for the past several years. The growth of online courses does not appear to be slowing. The purpose of this study was to examine the origins of online education at Tarleton State University, to compare course completion and student academic performance between online and traditional courses, and to develop a predictive model for students’ successful completion of online courses. Archival data from the Tarleton student records system was collected using the Structured Query Language. Descriptive statistics were used to analyze student characteristics. Chi-square analysis was used to determine if significant differences existed between students enrolled in online and traditional courses when comparing course completion and academic performance. Analysis found significant differences existed in both course completion and academic performance for students enrolled in online vs. traditional courses. Additional analysis indicated significant differences existed in course completion by course discipline. A predictive model was created using binary logistic regression and included the predictor variables age, student classification, term course load, and cumulative GPA. The final model correctly predicted successful completion of 85.5 percent of all cases.

It is well known that a classical solution of the initial value problem for a scalar conservation law may fail to exist on the whole domain of definition of the problem. For this reason, suitable generalized solutions of such problems, known as weak solutions, have been considered and studied extensively. However, weak solutions are not unique. In order to obtain a unique solution that is physically relevant, the vanishing viscosity method, amongst others, has been employed to single out a unique solution known as the entropy solution. In this thesis we present an alternative approach to the study of the entropy solution of conservation laws. The main novelty of our approach is that the theory of entropy solution of conservation law is presented in an operator theoretic setting. In this regard, the Order Completion Method for nonlinear PDEs, in the context of convergence vector spaces, is modified to obtain an operator equation which generalizes the initial value problem. This equation admits at most one solution, which may be represented as a Hausdorff continuous function. As a particular case, we apply our method to obtain the entropy solution of the Burger's equation.

La polarité cellulaire planaire (PCP) est une voie de signalisation conservée au fil de l’évolution et qui joue un rôle crucial dans l’établissement de la polarité des cellules et tissues en régulant la dynamique du cytosquelette. De nombreuses études ont démontré l’implication de la PCP dans les mécanismes développementaux importants comme la gastrulation ou la neurulation chez les mammifères, et la mutation des gènes centraux qui composent la PCP mène à de sévères malformations de nombreux organes, et par conséquent une mort néonatale. Van Gogh-like 2 (vangl2) est un des gènes centraux de la PCP et code pour une protéine transmembranaire de la voie de la PCP, et sa mutation conduit à une absence de fermeture de la gouttière neurale et la mort à la naissance chez les mammifères, y compris l'homme. Certaines études suggèrent que Vangl2 jouerait un rôle dans le guidage axonal, mais aussi l’arborisation dendritique des neurones de l’hippocampe et le nombre des épines dendritiques.Dans ce travail, je montre que Vangl2 est enrichi dans l’hippocampe adulte de souris, et plus précisément dans le gyrus denté (DG) et le stratum lucidum du CA3. De nombreuses études suggèrent que le réseau formé par ces sous-structures sous-tend des processus cognitifs spécifiques impliqués dans l’encodage et le rappel de la mémoire : le pattern separation et le pattern completion. Le pattern separation est un processus d’encodage d’informations similaires en représentations différentes, permettant la formation de souvenirs distincts malgré les similitudes entre les évènements. Le processus de pattern completion permet, à partir de stimuli partiels, de se remémorer un souvenir dans son intégralité. De récentes études suggèrent que la maturation des nouveaux neurones issus de la neurogenèse adulte dans le DG joue un rôle critique dans le maintien d'une balance qui existerait entre ces deux processus cognitifs. Bien que les mécanismes qui sous-tendent les deux processus soient encore mal compris, la connectivité du DG et du CA3 semble essentielle.J’ai ainsi formulé et testé l'hypothèse selon laquelle l'absence d'expression de Vangl2 affecterait ces processus mnésiques. Pour ceci, j'ai généré plusieurs mutants murins n'exprimant pas le gène vangl2 dans différentes régions du cerveau, que j'ai ensuite testé dans des paradigmes comportementaux requérant l’utilisation des processus de pattern separation et de pattern completion. Mes résultats suggèrent que Vangl2 dans le DG est essentiel dans le maintien d'une balance existante entre les deux processus, en régulant la maturation des neurones du DG. / Planar cell polarity (PCP) signaling is an evolutionary conserved pathway known to play a crucial role in the establishment of tissue polarity via a regulation of cytoskeleton dynamics. PCP signaling is essential during critical developmental stages, such as gastrulation or neurulation, to shape tissues and organs, and disruption of core PCP genes in mammals leads to severe malformations and neonatal death. Van Gogh-like 2 (vangl2) is one of the core PCP genes coding for a transmembrane protein, and its mutation leads to a failure of the neural tube closure in mammals, including humans. It has also been suggested that Vangl2 plays a role in axonal guidance, dendritic arborization of hippocampal neurons and dendritic spines number. I showed that Vangl2 protein is enriched in the hippocampus in the adult stage, precisely in the dentate gyrus (DG) and CA3 stratum lucidum subregions. These subregions have been proposed to sustain two cognitive processes involved in memory functions: pattern separation and pattern completion. Pattern separation allows the encoding of similar or overlapping inputs in distinct neuronal representations, allowing formation of new memory without interference of a previous similar encountered event. Pattern completion is described as the ability to guide the recall of an entire memory using partial sensory cues. Recent studies suggest a critical role for the maturation of adult-born granule neurons of the DG in the balance that may exist between pattern completion and pattern separation. Although the mechanisms of both cognitive processes are still debated, the connectivity between DG and CA3 appears to be essential. I thereby tested the hypothesis that in absence of Vangl2 in the brain, these two processes would be affected. I generated several conditional mutant mice in order to excise vangl2 gene in specific areas of the hippocampus, and tested them in behavioral paradigms requiring pattern separation or pattern completion processes. My data support my hypothesis that Vangl2 in the DG is essential for a balance between pattern separation and pattern completion, through the regulation of the maturation of DG neurons.

The purpose of this study was to examine the perceptions of students, administrators, and faculty of one community college on the factors that facilitate or inhibit collegiate student success toward associate degree completion. Degree completion was defined as graduating with an associate degree. The following research questions guided this study: 1) What support systems or resources are in place at the community college to assist students with degree completion? 2) What factors in the college student success course at this community college facilitate or inhibit successful degree completion? The case study was conducted in a single community college inNorth Carolina. Participants included 10 community college professionals and 5 students. Data were collected through face-to-face interviews and then transcribed. Pseudonyms were used to maintain participant anonymity. The data were analyzed through the process of coding. Findings identified eight themes in relation to facilitating and inhibiting degree completion at the community college level. These themes were: (a) curriculum, (b) advising, (c) support services, (d) relationships, (e) faculty status, (f) intrinsic motivation, (g) developmental courses, and (h) external factors. Conclusions of the research study and recommendations for further research were determined.

<p>Senaste årens ökade internationalisering har gjort att antalet stora multinationella företag och koncerner ökat. Följden har blivit ett ökat behov av att kunna göra jämförbara tolkningar av finansiella rapporter för bolag i olika länder. Detta har lett till införandet av internationella redovisningsstandarder (IFRS/IAS), som gäller även för svenska koncerner från och med 2005. Då länderna historiskt haft olika värderingsprinciper finns risk för konflikt mellan det som varit traditionellt i Sverige, d.v.s. en mer försiktighetsinriktad syn på redovisningen, och matchnings-principen som är aktuell för dagens fokus på redovisning till verkligt värde. Problemfrågan är om de större verkstadsindustribolagen har en mer försiktighetsinriktad syn vid sin successiva vinst-avräkning. Stödjer metoden bolagen att visa en rättvisande bild av dess resultat och ställning? Syftet med uppsatsen har varit att söka svaret på vilken av försiktighets- eller matchnings-principen som väger tyngst för utvalda bolag när de gör successiv vinstavräkning. Motsvarar det kapitalmarknadens intresse med vinstavräkning till verkligt värde? För att söka svaren har strategin varit att göra en fallstudie där ett antal intervjuer gjorts med två bolag inom verkstadsindustribranschen. Då antalet direkta källor är begränsade bör inga generaliseringar göras av redovisat resultat. Uppsatsen baserar sig på redovisningsteorierna försiktighets- och matchningsprincipen samt den successiva vinstavräkningsmetoden. Försiktighetsprincipen innebär bl.a. att vinster inte ska tas upp förrän de har realiserats. Matchningsprincipen däremot innebär att intäkter och kostnader ska matchas och redovisas i samma period. Sistnämnda principen stödjer den successiva vinst-avräkningen som har till syfte att lyfta fram intäkter och kostnader i proportion till färdigställandet av varan/tjänsten. Sammantaget anser intervjuade bolag att den successiva vinstavräkningen hjälper dem att visa en rättvisande bild av bolagets resultat och ställning. Det framgår att koncernen, som det ena bolaget verkar i, historiskt haft en tradition att vara försiktiga. Analysen här är att försiktighetsprincipen fortfarande väger tyngst och att införandet av nya standarder antas först då det kulturella arvet mognat och hunnit ifatt. Men då omsättning endast till mindre del består av kundorders som avräknas successivt ger den totala externredovisning en rättvisande bild av bolaget. Slutsatser för det andra bolaget är att de tydligare använder matchningsprincipen vid värderingar för successiva vinstavräkningen. Tolkningen är att koncernen under en längre tid använt US-GAAP, vilka de internationella standarderna baseras på. Det medför att de redan värderar till verkligt värde och tillfredsställer därmed de privata kapitalmarknadsplacerarna.</p>

Finding the maximum size of a matching in an undirected graph and finding the maximum size of branching in a directed graph can be formulated as matrix rank problems. The Tutte matrix, introduced by Tutte as a representation of an undirected graph, has rank equal to the maximum number of vertices covered by a matching in the associated graph. The branching matrix, a representation of a directed graph, has rank equal to the maximum number of vertices covered by a branching in the associated graph. A mixed graph has both undirected and directed edges, and the matching forest problem for mixed graphs, introduced by Giles, is a generalization of the matching problem and the branching problem. A mixed graph can be represented by the matching forest matrix, and the rank of the matching forest matrix is related to the size of a matching forest in the associated mixed graph. The Tutte matrix and the branching matrix have indeterminate entries, and we describe algorithms that evaluate the indeterminates as rationals in such a way that the rank of the evaluated matrix is equal to the rank of the indeterminate matrix. Matroids in the context of graphs are discussed, and matroid formulations for the matching, branching, and matching forest problems are given.

In this thesis we describe an approach to automatically invent/explore new mathematical theories, with the goal of producing results comparable to those produced by humans, as represented, for example, in the libraries of the Isabelle proof assistant. Our approach is based on ‘schemes’, which are formulae in higher-order logic. We show that it is possible to automate the instantiation process of schemes to generate conjectures and definitions. We also show how the new definitions and the lemmata discovered during the exploration of a theory can be used, not only to help with the proof obligations during the exploration, but also to reduce redundancies inherent in most theory-formation systems. We exploit associative-commutative (AC) operators using ordered rewriting to avoid AC variations of the same instantiation. We implemented our ideas in an automated tool, called IsaScheme, which employs Knuth-Bendix completion and recent automatic inductive proof tools. We have evaluated our system in a theory of natural numbers and a theory of lists.
