Preparing students for the transition from college to work /

The purpose of this study was to examine the perceived preparedness of college students for the transition from college to full-time employment. The study was concerned with the interest and rationale behind developing a required Exit Course for college students in order to improve the college to work transition. As well, possible content of an Exit Course was evaluated. The importance of addressing college to work transitions is highlighted by two phenomena. First, there are specific employability skills that employers in Canada are seeking in newly hired employees. Second, the provincial government in Ontario is determining college funding based on graduate employment statistics which are measured by graduate satisfaction, graduate employment, and employer satisfaction. The research concentrated on the following stakeholders involved in the transition from college to work: (a) current students, (b) recent graduates, (c) support staff who assist students in college to work transition (Career Educators), and (d) employers. Through qualitative research, including focus groups and interviews, these stakeholder groups participated in the research to determine if the Exit Course was a viable solution to facilitate the transition from college to work. Focus groups were conducted with current students, while one-on-one, semi-structured interviews were conducted with recent graduates, Career Educators, and employers. Common themes elicited from the participants included the following: (a) although students were perceived by the participants of this study to be technically prepared for employment, they were perceived to have weak job search skills and unrealistic expectations of the world of work unless they had received the benefits of a Co-operative Education experience; (b) an Exit Course was seen as a viable solution to the issues involved in college to work transition; (c) an Exit Course should be comprised of skills necessary to obtain and succeed in a job and the course should be taught by individuals with extensive qualifications in this area; and (d) there is a need to develop college and business partnerships to ensure that students are connected to employers. Educators within post secondary institutions, specifically colleges, can benefit from the information provided within this study to gain a better understanding of the perceived level of preparedness of students for the transition from college to work. Suggestions with regard to how to improve this transition were made, with specific reference to the addition of an Exit Course as one possible solution.

LEISURE CONNECTIONS AND HEALING FOLLOWING TRAUMA: CONSTRUCTIVIST AND EXISTENTIAL REFLECTIONS AND THEORIZING

Trauma can have lasting effects on health (CAMH, 2010; DSM-IV, 1994; Lazarus, 1966), negatively influencing meanings and experiences of leisure in relation to health (Griffin, 2002, 2005; Meister & Pedlar, 1996). This interpretive grounded theory explored understandings of leisure during Leisure Connections and how Leisure Connections provides a context for healing from trauma. Data included observations, interviews with six participants, and reflection cards. Nine themes emerged: responding to trauma in leisure, letting go of familiar coping patterns and opening to joy, being in the moment of small steps and simple things, changing understandings of self, reconnecting with the body, shifting to internal motivation, choosing, reconnecting with others in leisure, balancing life with leisure, and growth and connections. Leisure Connections supported participants to explore leisure and its benefits as issues arise, to understand and respond differently. Leisure Connections provides boundary situations critical for existential growth and opportunity to change coping patterns.

Alkali insoluble glucan extracted from Acremonium diospyri is a more potent immunostimulant in the Indian White Shrimp, Fenneropenaeus indicus than alkali soluble glucan

E¡ect of an extraction method on the structure of glucan and its immunostimulatory response in Fenneropenaeus indicus was investigated. Here we extracted alkali insoluble glucan (AIG) and alkali soluble glucan (ASG) from a ¢lamentous fungi Acremonium diospyri following alkali^acid hydrolysis and the sodium hypochlorite oxidation and dimethyl sulphoxide extraction method respectively. Structural analysis showed that 85% of glucan in AIG was a (1 !3)-b-D-glucan and it increased the prophenoloxidase and reactive oxygen intermediate activity when administered to F. indicus. On the other hand, ASG, which contained 93% (1 !3)-a-glucan, did not induce signi¢cant immune response in shrimp. Here we report that the di¡erence in immunostimulatory potential between AIG and ASG is due to the di¡erence in the percentage of (1 !3)-b-D-glucans present in each preparation, which varies with the method of extraction employed. Also our observations suggest that glucan can be used as a potential immunostimulant to shrimp, provided it contains (1 !3)-b-D-glucan as the major fraction.

Anisotropic adaptive resolution of boundary layers for heat conduction problems

We deal with the numerical solution of heat conduction problems featuring steep gradients. In order to solve the associated partial differential equation a finite volume technique is used and unstructured grids are employed. A discrete maximum principle for triangulations of a Delaunay type is developed. To capture thin boundary layers incorporating steep gradients an anisotropic mesh adaptation technique is implemented. Computational tests are performed for an academic problem where the exact solution is known as well as for a real world problem of a computer simulation of the thermoregulation of premature infants.

Modellierung und numerische Simulation der Thermoregulation von Früh- und Neugeborenen

Bei frühgeborenen Säuglingen spielt die Thermoregulation zur Aufrechterhaltung einer überlebenswichtigen Körpertemperatur durch Wärmeproduktion, -abgabe bzw. -aufnahme eine entscheidende Rolle. Der Einsatz moderner Inkubatoren soll die körpereigenen Thermoregulatoren unterstützen, und es ist im Hinblick auf verschiedene medizinische Fragestellungen wünschenswert, diesen Prozess modellieren zu können. Wir stellen ein einfaches Modell auf der Basis von partiellen Differentialgleichungen vor und beschreiben detailliert die numerische Simulation mit Hilfe einer Finite-Volumen-Methode. Dazu wird ein zweidimensionales Modell eines Frühgeborenen trianguliert und das Modell diskretisiert. Zahlreiche numerische Resultate zeigen die Qualität unseres Modells.

Stability of preconditioned finite volume schemes at low Mach numbers

In [4], Guillard and Viozat propose a finite volume method for the simulation of inviscid steady as well as unsteady flows at low Mach numbers, based on a preconditioning technique. The scheme satisfies the results of a single scale asymptotic analysis in a discrete sense and comprises the advantage that this can be derived by a slight modification of the dissipation term within the numerical flux function. Unfortunately, it can be observed by numerical experiments that the preconditioned approach combined with an explicit time integration scheme turns out to be unstable if the time step Dt does not satisfy the requirement to be O(M2) as the Mach number M tends to zero, whereas the corresponding standard method remains stable up to Dt=O(M), M to 0, which results from the well-known CFL-condition. We present a comprehensive mathematical substantiation of this numerical phenomenon by means of a von Neumann stability analysis, which reveals that in contrast to the standard approach, the dissipation matrix of the preconditioned numerical flux function possesses an eigenvalue growing like M-2 as M tends to zero, thus causing the diminishment of the stability region of the explicit scheme. Thereby, we present statements for both the standard preconditioner used by Guillard and Viozat [4] and the more general one due to Turkel [21]. The theoretical results are after wards confirmed by numerical experiments.

Preconditioner updates applied to CFD model problems

In the present paper we concentrate on solving sequences of nonsymmetric linear systems with block structure arising from compressible flow problems. We attempt to improve the solution process by sharing part of the computational effort throughout the sequence. This is achieved by application of a cheap updating technique for preconditioners which we adapted in order to be used for our applications. Tested on three benchmark compressible flow problems, the strategy speeds up the entire computation with an acceleration being particularly pronounced in phases of instationary behavior.
