description: The ability to utilize a motor vehicle is paramount in modern society. The impact of driving and the relationship it has with personal independence and quality of life is crucial. In the United States, people with a corrected visual acuity worse than 20/40 are denied general licensing to operate a car. Although, in over 40 states those who do not meet general visual acuity requirements and have low vision are able to gain special licensure through the use of a bioptic telescope. A bioptic telescope is a miniature telescope mounted to a carrier lens that allows the user increased vision capacity. The rationale behind the use of a bioptic telescope for driving is that it provides the driver with low vision the ability to view objects and assess their surroundings while driving in a safe manner that they otherwise would not be able capable of.Little research has been conducted to assess bioptic drivers in relation to the normal driving population and to people with similar visual acuity licensed without a bioptic. Prior research has returned mixed results on the safety and application of bioptics for driving. The nature of visually impaired driving is a constant additional workload to baseline driving. The workload and attention demand imposed by low vision and bioptic driving is analyzed through lateral control modeling of steering wheel reversals to assess baseline driver performance in an on-road pilot experiment.
description: From the results, the study found that driving with a bioptic system and low vision significantly differs from the normal population in regard to lateral control. The attention demand and workload required by driving with a bioptic system was found to be elevated compared to the normal population and non-bioptic visually impaired drivers. With bioptic system users committing steering corrections at a higher frequency than the normal population. The study also found that even though the corrections made by drivers who use a bioptic are significantly larger than the normal sighted population, the steering corrections were not significantly different than visually impaired non-bioptic system drivers. In fact, non-bioptic visually impaired drivers were found to commit significantly larger reversals than visually impaired drivers who use a bioptic.
description: Furthermore, it is apparent that visually impaired drivers exhibit more workload and attention demand while driving. The comparison between bioptic and non-bioptic visually impaired drivers did not deem the presence of a bioptic system to decrease driver safety in baseline driving. Future work should be done to assess the workload and performance of drivers who use a bioptic during explicit cases of bioptic use, such as sign scanning or object detection by incorporating a suite of lateral control metrics.

description: Objectives: Stroke can happen to people away from home. It is unknown whether non-resident and resident stroke patients have equal access to thrombolysis. Materials and methods: Consecutive patients cared for by the Stroke Emergency Mobile between 2011 and 2016 after prompting suspicion of acute stroke during the emergency call were included in our registry. Patients were categorized as residents or non-residents based on their main address. Clinical characteristics, thrombolysis rates, and time intervals from symptom onset/last seen well to alarm and to thrombolysis were compared between groups adjusting for age, pre-stroke modified Rankin Scale (mRS) score, and National Institutes of Health Stroke Scale (NIHSS) score. Results: Of 4,254 patients for whom a stroke dispatch was activated, 2,451 had ischemic or hemorrhagic strokes, including 73 non-residents. Non-resident stroke patients were younger (median 69.4 vs. 76.6 years, p < 0.001), had less pre-stroke disability (mRS ≥ 2:17.8 vs. 47.5%, p < 0.001) and less severe strokes (median NIHSS 4 vs. 5, p = 0.02). Thrombolysis rates were higher in non-residents (30.9 vs. 22.0% of ischemic stroke patients, p = 0.04) and emergency calls were made faster (symptom onset/last-seen-well-to-alarm time 35 vs. 144 min, p = 0.04). A lower proportion of non-residents had unknown time of symptom onset (21.9 vs. 46.4%, p < 0.001). For patients with known time of symptom onset, thrombolysis rates, and prehospital delays were similar among non-residents and residents. Conclusion: In this study, non-resident stroke patients had higher rates of thrombolysis than residents. This may be explained by a lower proportion of patients with unknown time of symptom onset.

description: The effect of the support in heterogeneous catalysis is very important but often poorly understood. The reaction of tetraneopentylchromium(IV) with Sylopol 952, a silica gel used industrially as a carrier for alpha-olefin polymerization catalysts, has been investigated and compared with the previously reported reaction on Aerosil 200, a fumed silica often used to model catalyst supports. Grafting, thermolysis, and metathetical exchange reactions of chromium(IV) neopentylidenes were found to be the same on either Aerosil 200 or Sylopol 952. However, reactivity of the grafted organochromium fragments towards ethylene was found to be quite different on the two supports. The research described in this thesis also explores the polymerization activity of bis(neopentyl)chromium(IV) fragments at higher ethylene pressures than were previously investigated. This result has greatly altered thinking about the nature of the active site for olefin polymerization over surface organochromium fragments. The supported bis(neopentyl)chromium(IV) is no longer believed to require thermal activation to create chromium alkylidene active sites. A possible mechanism is postulated. Propylene polymerization by the Aerosil-supported chromium alkylidene was observed as a slow pseudo-first-order reaction. The kinetics were examined at the gas-solid interface by in situ FTIR spectroscopy and the second-order rate constant compared to those previously measured for ethylene and 1-hexene.

description: A sizable body of research has been conducted in second/foreign language testing and assessment (LTA) that provides reliability and validity evidence to the use of integrated writing tasks. However, relatively little research has been conducted to examine integrated writing tasks as a means to provide diagnostic insight for teachers and learners. The current study aims to fill in this lacuna by carrying out mixed methods research, proceeding from quantitative estimation to qualitative exploration.
description: The procedures the current study adopted are as follows. First, an integrated writing assessment was developed with the topic of “eating for professional purposes,” and 315 Chinese college-level English as a Foreign Language (EFL) examinees took the test. The collected essays were rated by two experienced raters who have extensive experience of teaching writing to second/foreign language student writers. As for quantitative data analysis, a log-linear cognitive diagnostic model (LCDM) was applied to the integrated writing data. The integrated writing task was conceptualized as consisting of language use, source use, and content, with each of these unobservable attributes measured by surrogate indicators. Then, a Q-matrix, which specifies which items require which attributes for correct response, was developed for LCDM analysis.
description: Results showed that all the attributes were positively correlated, yet to varying degrees. The strongest association was observed between source use and content, with an estimated correlation of .86. This was followed by the correlation between language use and source use (r=.71). Language use and content had the lowest correlation (r=.25). Also, item parameters indicated that language use is more important than the other attributes for obtaining a passing score for the indicators. Lastly, the test-taker classification showed that it is impossible to master source use without other attributes, nor was it possible to master other attributes without source use, demonstrating its dependence on other attributes.
description: To analyze the qualitative data, content analysis was applied. The themes that emerged out of the data include the raters/teachers’ identification of important components of integrated writing tasks and the connections between the constructs of integrated writing tasks. The findings of this study have practical implications for the teaching and learning of integrated writing.

description: Background: High tibial osteotomy is a surgical procedure to treat medial compartment osteoarthritis in varus knees. The reported success rates of the procedure are inconsistent, which may be due to sagittal plane alignment of the osteotomy. The objective of this study was to determine the effect of changing tibial slope, for a range of tibial wedge angles in high tibial osteotomy, on knee joint contact pressure location and kinematics during continuous loaded flexion/extension. Methods: Seven cadaveric knee specimens were cycled through flexion and extension in an Oxford knee-loading rig. The osteotomy on each specimen was adjusted to seven clinically relevant wedge and slope combinations. We used pressure sensors to determine the position of the centre of pressure in each compartment of the tibial plateau and infrared motion capture markers to determine tibiofemoral and patellofemoral kinematics. Findings: In early knee flexion, a 5 degree increase in tibial slope shifted the centre of pressure in the medial compartment anteriorly by 7mm for a 15 degree wedge (p<0.001), (from the neutral slope/wedge position). At all wedge angles, increasing the tibial slope resulted in the tibia translating anteriorly (p<0.001). Interpretation: Changes to the tibial slope during high tibial osteotomy for all tested wedge angles shifted the centre of pressure in both the medial and lateral compartments substantially and altered knee kinematics. Tibial slope should be controlled during high tibial osteotomy to prevent unwanted changes in tibial plateau contact loads.

description: Consumer buying behavior towards branded footwear is influenced by various factors, including brand image, quality perception, marketing strategies, and digital engagement. This review examines the key drivers shaping consumer preferences, such as trust, brand loyalty, price sensitivity, and the role of social media in purchase decisions. With the rise of e-commerce and digital marketing, consumer interactions with footwear brands have changed significantly, leading to a shift in shopping habits. The study highlights how a strong brand image enhances consumer trust, fosters loyalty, and influences word-of-mouth recommendations. Additionally, it explores the impact of promotional strategies and pricing on consumer purchasing decisions. Understanding these factors is crucial for footwear brands to refine their marketing approaches and maintain a competitive edge. By analyzing consumer behavior trends, this review provides insights into how branding and digital marketing strategies can shape the future of the branded footwear industry.
Context-based coalition access control for ubiquitous computing

Subjects: subject: Computer Science.

description: The need for coalition access control among individuals and organizations has increased significantly in the past years as the need for spontaneous access to information increases. However, a significant deterrent to the ability to connect in a spontaneous manner in coalition collaborative applications is the difficulty in users from different domains being able to access resources or services located and owned by other entities. Coalition access control encompasses control mechanisms dealing with access between users of two or more different organizations or enterprises. These users could be co-located or remotely located. The thesis first presents a delegation based D-TMAC model that extends traditional TMAC across organizations for formal coalition environments, and a context-based coalition access control model, which apply context information as conditions on delegation. Then the thesis proposes a Session-based Coalition Access Control Architecture (SCACA) and provides practical implementation that enables dynamic coalition access control over a communication session in a spontaneous manner. The presented system architecture and methodology leverages the IETF SIP protocol as an underlying communication mechanism in order to greatly minimize the administration overhead and rapidly adapt the dynamic nature of access control in spontaneous coalition environments. The result is that, during a spontaneous coalition communication across organizations, every endpoint can access other endpoints' resources and share its own resources to all the other endpoints as well. Moreover, these privileges will dynamically change as the status of the coalition communication changes.

description: Variation in feeding behaviour was studied among young individuals of pumpkinseed (Lepomis gibbosus) and yellow perch (Perca flavescens). Three types of food, Drosophila, Daphnia and Artemia were used for the experiments. Eight individuals of pumpkinseed differed significantly in their number of feeding attempts, in time interval between feeding attempts (in the beginning, middle and towards the end of the experiment), feeding angle, number of unsuccessful attempts and regurgitations. Most of the differences in the time interval between feeding attempts were observed in the middle and towards the end of the experiment. When the experimental diet was composed of three types of foods (Drosophila, Daphnia and Artemia) in a mixture, the total number of feeding attempts in the experiment decreased. Mixing the food types also reduced the feeding efficiency of individuals which was evidenced by the increased time interval between the feeding attempts and the increased unsuccessful attempts and regurgitations. Individuals of pumpkinseed showed the highest preference for Daphnia. On the basis of the above feeding variables, groups of individuals of differing feeding patterns were identified. Similar patterns were observed for the eight individuals of yellow perch. Perch fed more efficiently on Artemia, however, two individuals of perch were more efficient on feeding on Daphnia. Effects of the presence of conspecifics and increasing population density were examined on the variation among individuals of the pumpkinseed and yellow perch, for two types of food, (Daphnia and Artemia), separately and in a mixture. The effects of conspecifics were not equal on each individual of pumpkinseed and yellow perch. Only the weaker individuals were affected more by the presence of other conspecifics than the stronger ones. The increasing population density of conspecifics increased the variation among the individuals of both species. The effect of the presence of heterospecifics (yellow perch) were also examined on individuals of pumpkinseed for similar food types and feeding variables. At low experimental densities the effects of the heterospecifics were not significant. However, at high densities yellow perch affected the feeding behaviour of pumpkinseed individuals significantly. The effects of conspecifics on pumpkinseed were always greater than heterospecifics. Yellow perch did not affect the feeding behaviour of all the individuals of pumpkinseed equally.

description: A computer program was developed to determine the interaction curves and the isoload contours for L-Sections reinforced concrete columns. The program used the generally accepted assumption of plane sections remaining plane, but the maximum limiting concrete strain was a variable parameter. The isoload contours are relatively smooth curves with deviations only occurring in cases where the neutral axis is parallel to a major dimension of the section. This deviation from the general shape of the curve increases as the allowable concrete strain is increased and as the section is subjected to more compression. The ultimate biaxial moments increase by 3 to 6% (depending on the load level) when the maximum allowable concrete strain is increased from 0.003 to 0.004. The ultimate biaxial curvatures increase by 35 to 48% (depending on the load level) when the maximum allowable concrete strain is increased from 0.003 to 0.004.

description: The present study examined the relationship between overall wellness, quality of sleep, satisfaction with life, and burnout among mental health counselors. Additionally, the current study examined age, gender, race, years of experience, type of license, client age, client presenting issues, location, number of weekly telehealth sessions, number of weekly sessions, type of agency setting contribute to mental health counselor’s self-reports of burnout. The study looked at the difference between temporarily and fully licensed mental health counselor’s self-reports of satisfaction with life, overall wellness, and quality of sleep.
description: The present study examined the relationship between four variables (overall wellness, quality of sleep, satisfaction with life, and burnout) for practicing mental health counselors through the use of a demographics questionnaire, the Five Factor Wellness Inventory FFWEL), the Pittsburgh Sleep Quality Index (PSQI), Satisfaction with Life Scale (SWLS), and Counselor Burnout Inventory (CBI). A sample of 80 mental health counselors across the United States participated in the study. All participants were anonymous. The statistical analyses were completed using the Software Program for Statistical Analysis (SPSS) using correlational matrices, standard multiple regressions, and MANOVA analyses.
description: Results revealed burnout was directly related to overall wellness and satisfaction with life. Similarly, results showed a direct relationship between overall wellness and satisfaction with life. Results also showed counselor’s age and type of agency setting significantly increased the risk of burnout among practicing mental health counselors. Recommendations for mental health counselors include: establishing a self-care routine, integrating wellness in supervision and consultation, and modeling private practice modalities into all type of agency. Recommendations for counselor educators: increasing wellness and self-care practice in coursework and departmental workshops or trainings, providing appropriate feedback and encouragement, and modeling healthy behaviors of wellness. Areas for future research are also discussed.

description: Malaria is a global health burden and with recent strains on health care infrastructure globally case eradication efforts have plateaued. A top priority in eradication efforts moving forward is to develop vaccines capable of producing a long lived and effective antibody response in order to prevent reinfection. One noted roadblock in this effort is the Plasmodium induced defects in the humoral immune system, the arm of the immune system responsible for antibody production. The factors contributing to formation of effective antibody responses, as those which produced long lived immune memory are still an area of very active research. The work described here seeks to understand the influence that blood flow, and thus oxygen availability has over the formation of these antibody responses.

description: Dynamic compression by multiple shocks is used to compress iron up to 560 GPa (5.6 Mbar), the highest solid-state pressure yet attained for iron in the laboratory. Extended x-ray absorption fine structure (EXAFS) spectroscopy offers simultaneous density, temperature, and local-structure measurements for the compressed iron. The data show that the close-packed structure of iron is stable up to 560 GPa, the temperature at peak compression is significantly higher than expected from pure compressive work, and the dynamic strength of iron is many times greater than the static strength based on lower pressure data. The results provide the first constraint on the melting line of iron above 400 GPa.

description: Induction of cell proliferation requires a concomitant increase in the synthesis of glycosylated lipids and membrane proteins, which is dependent on ER-Golgi protein transport by CopII-coated vesicles. In this process, retrograde transport of ER resident proteins from the Golgi is crucial to maintain ER integrity, and allows for anterograde transport to continue. We previously showed that expression of the CopI specific SNARE protein Use1 (Unusual SNARE in the ER 1) is tightly regulated by eIF4E-dependent translation initiation of Use1 mRNA. Here we investigate the mechanism that controls Use1 mRNA translation. The 5′UTR of mouse Use1 contains a 156 nt alternatively spliced intron. The non-spliced form is the predominantly translated mRNA. The alternatively spliced sequence contains G-repeats that bind the RNA-binding protein G-rich sequence binding factor 1 (Grsf1) in RNA band shift assays. The presence of these G-repeats rendered translation of reporter constructs dependent on the Grsf1 concentration. Down regulation of either Grsf1 or Use1 abrogated expansion of erythroblasts. The 5′UTR of human Use1 lacks the splice donor site, but contains an additional upstream open reading frame in close proximity of the translation start site. Similar to mouse Use1, also the human 5′UTR contains G-repeats in front of the start codon. In conclusion, Grsf1 controls translation of the SNARE protein Use1, possibly by positioning the 40S ribosomal subunit and associated translation factors in front of the translation start site.
Kant's Leibniz-critique in the amphiboly chapter of the "Critique of Pure Reason".
Creators: name: Sears, Robert.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1999
Subjects: subject: Philosophy.

description: In this dissertation it is argued that Kant's critique of Leibniz as found in the amphiboly chapter of the Critique of Pure Reason derives from his theory of reflection. It is argued further that this unfocused and fragmentary amphiboly chapter, which contains the Leibniz-critique, can be seen to have a previously unsuspected unity to it. The keys to perceiving this unity are the appendix's purpose, structure and mosaic composition. The primary purpose of the appendix is not to present Kant's criticisms of Leibniz as is commonly thought, but rather it is to sketch his theory of reflection. Not only is this attested to by Kant himself (A 270/B 326), it is also made evident by the structure of the appendix. Structurally, the appendix is built around an introduction to the operation of transcendental reflection and a discussion of the concepts of reflection, this being the structure of each of the first three sections. By means of each pair of concepts of reflection Kant claims to summarize the basic tenets and origin of Leibniz's philosophy. Kant also claims that Leibnizls whole philosophy rests on one seminal error, which will be shown to be the omission of the operation of transcendental reflection. To be sure, Kant claims Leibniz made a number of other errors, but these various errors all derive from the omission of transcendental reflection. While this omission can be used to explain the other more well-known epistemological mistakes with which Kant charges Leibniz, it is undeniable that there are certain textual difficulties with the appendix. These can be dealt with by the hypothesis that the different sections were composed at different times and than pieced together without detailed revisions. If such a mosaic composition is granted, then some allowance can be made for the noticeable incongruities between these sections and for occasional problematic passages. This does not, however, warrant the claim that the appendix is not properly placed or unimportant. On the contrary, supplemented by clearer statements of Kant's theory of reflection and of his Leibniz-critique, the following interpretation shows that the appendix is properly placed and integral to the primary aims of the Critique of Pure Reason.

description: En esta tesis se investiga la adquisicion de las palabras compuestas del espanol por hablantes del fines. La investigacion se centra en dos tipos de compuestos, i.e. los compuestos N-N (coche cama) y los deverbales (matamoscas), empezando por un analisis comparativo de estos compuestos del espanol y del fines. En el caso de los compuestos N-N, la productividad minima de los compuestos del espanol en comparacion con los del fines se explica a partir del 'Parametro de los compuestos' (Snyder, 1995), mientras que la direccionalidad opuesta del nucleo y del modificador se basa en la propuesta del 'Marcador de palabra' (Harris, 1991; Piera, 1995). Las diferencias mas importantes entre los compuestos deverbales en las dos lenguas son la direccionalidad y la estrategia de formacion, las cuales se explican con el modelo LMBM de Beard (1995). Las hipotesis se basan en la influencia del L1 en la adquisicion de las diferencias mencionadas. La parte empirica de la tesis consiste en un estudio con 19 hablantes de fines, 13 de nivel intermedio y 6 de nivel avanzado. Los compuestos se obtuvieron a partir de dos pruebas, una de dibujos y otra de parafrasis para las que los aprendices debian proporcionar el compuesto correspondienete. Los resultados confirman la influencia del L1 tanto en el cas o de los compuestos N-N como de los deverbales. La variacion en la productividad de los compuestos N-N se explica con la propuesta de Snyder. Por lo que se refiere al 'Marcador de palabra' los resultados indican que no parece formar parte de la representacion mental del la Interlengua de los sujetos. Por lo que se refiere a la direccionalidad de los deverbales, ademas de ser mas problematica su adquisicion, lo cual puede explicarse por el hecho de que la opcion del fines---como la del ingles---represente una estructura marcada.
Interpersonal problem-solving and deterrence: Effects on prison adjustment and recidivism.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1990
Subjects: subject: Psychology, Social.

description: This study investigated the relationships between problem-solving ability, perceived aversiveness and deterrence of sanctions for institutional misbehaviour, and subsequent institutional and community adjustment in convicted adult offenders. Subjects completed a battery of tests designed to assess certain interpersonal problem-solving skills. They also provided subjective ratings of aversiveness and deterrence value of 10 common institutional sanctions. Institutional conduct was subsequently monitored for 3 months following testing. In addition, further criminal activity was monitored for a period of 1 year following release from incarceration. The results reveal a modest relationship between problem-solving ability and institutional adjustment and a much stronger relationship between problem-solving ability and subsequent recidivism. Poorer problem-solvers incurred more institutional charges in the early phase of incarceration and more followup criminal charges. In contrast, ratings of aversiveness or deterrence were more strongly related to institutional adjustment and in general were not predictive of subsequent criminal recidivism. Perceptions of aversiveness or deterrence of sanctions, though positively correlated, were not identical. For example, a number of subjects rated the sanctions as aversive but not deterrent, indicating that to some extent these factors are independent. Of the two, perceived aversiveness appeared to be a more accurate predictor of actual institutional behaviour, especially where there was a discrepancy between perceived aversiveness and perceived deterrence. There was some evidence of a relationship between problem-solving ability and perceptions of aversiveness. Good problem-solvers tended to rate sanctions as more aversive than poor problem-solvers. Thus, the greater cognitive flexibility that results from well-developed problem-solving skills may potentiate perceptions of aversiveness. In addition, subjective perceptions of aversiveness and deterrence of sanctions were found to be unstable over time. This was unrelated to whether or not subjects had actually experienced the sanction in the interim between pretesting and posttesting. The findings are discussed in terms of their implications for deterrence theory and treatment-rehabilitation.

description: Students do their best work when they have a sense of agency around science and science learning. Scientific practices like argumentation and critique are areas in which students’ agency is especially visible, as they require many points of decision-making and evaluation. While argumentation and critique are fundamental practices in both classroom and professional science, these practices can remain contrived if students do not have an agentic relationship to them. This study investigated two aspects of support for students’ agency, especially as it relates to critique. First, a case study in a 5th grade classroom uncovered the criteria (e.g., standards) which the students and their teacher used to make decisions, as well as how those criteria were negotiated over the course of a unit. Findings suggested that students used diverse criteria which fluctuated depending on the task and object of critique, and that both parties’ negotiation for influence was mutually supportive for learning. Second, an invariance study aimed to advance the measurement quality around teachers’ support for student agency, especially in measuring their growth over time. Using invariance analysis, an appropriate measurement model was generated so that teachers’ scores could be compared across time by using a similar measuring stick at each occasion. Findings highlighted areas where response shifts occurred and the measuring sticks were not comparable, ultimately advancing knowledge of how teachers interpret items related to agency and improving efforts to measure teachers’ support for student agency. Overall, students’ sophisticated use of criteria plays an important role in the extent to which they have a sense of agency around science learning. Teachers’ own sense of agency around science may impact how they support students, and efforts to measure teachers’ support for student agency might benefit from attention to these issues.
Are the police racist? A critical assessment of the literature on police minority relations.

Subjects: subject: Sociology, Criminology and Penology.

description: This thesis proposes that the systemic differential treatment of aboriginal and racial minority peoples in the criminal justice system is at least partly attributed to police racism. Discrimination, which refers to the negative treatment toward out-groups (Elliot and Fleras, 1992:330), is systemic in policing and not isolated to racial minorities. The lower class and others considered deviant are also routinely discriminated against. However, the visibility of racial minorities and aboriginal peoples makes them particularly susceptible to police actions. Because the role of policing necessitates the identification of not only criminals but also potential criminals, this identification must have visible characteristics, or cues. Consequently, the police officer comes to develop these visible characteristics to identify criminals. It is thus the visibility of racial minorities which results in their being categorized as criminal and subsequently the focus of police suspicion. Chapter one reviews the literature in other democratic countries to determine the role of police decision-making in the over-representation of aboriginals and racial minorities in the criminal justice system. Establishing the over-representation of aboriginal peoples and visible minorities in Canada, chapter two examines various explanations for this. Chapter three presents the allegations of police racism by visible minority and aboriginal peoples. (Abstract shortened by UMI.)

description: The purpose of the present study was to better understand creativity and creative development as well as the many factors that contribute to the processes that lead young adults to channel their creativity in various fields and degrees of social acceptance. Adolescents, parents, teachers, educational systems, and society as a whole would benefit from a deeper understanding of how creative individuals interact with, shape and seek out environments to fulfil their various creative needs. Society can ill-afford the incalculable loss of squandered or negatively applied creative talent. The present project was guided by an interactionist (Woodman & Schoenfeldt, 1989)/ecological (Harrington, 1990) process model of creativity which takes into account the four major strands (person, process, product and press) of inquiry involved in creativity research and provides the basis for a robust conceptual framework for their holistic study. To this end, a constructivist, qualitative approach was adopted. The research design for the present study adheres most closely to the social constructionist interpretation and application of the grounded theory method as outlined by Charmaz (1990, 2000). Biographical questionnaires and interviews, or "guided conversations", were undertaken with twenty-six (26) participants; ages ranging from 17-31 with the majority (22) aged between 18-24. They were chosen because they are notably creative in fields of varying degrees of social acceptance and because they represent a wide variation of schooling experiences and backgrounds. Specifically, they represented, among many others, high school valedictorians and drop-outs, graffiti artists, JUNO nominated musicians, painters, writers, actors, as well as scientific innovators. They were selected as a result of high school peer and teacher nominations, nominations from two guidance counsellors in a high school, judgement of products, snowballing, and informal peer nominations. Insights resulting from the questionnaire and interviews include a grounded theory process model for the "evolution" of the creative person. In addition, the methodological implications of adopting a constructivist perspective together with the newer relational views of research validity are examined; as are the implications the findings hold for educational policy and practice as well as the potential implications the research holds for the future study of young adults and creativity.

description: Glucose regulation, in both patients with diabetes and nondiabetes patients, has been shown to be associated with neuropsychological function, particularly episodic memory. The main purpose of this study was to examine this association in a large sample of young nondiabetic adults, using a repeated-measures design in which participants were assessed under both, glucose and saccharin conditions. Regression analyses revealed that glucoregulatory indices based on evoked glucose levels significantly predicted the verbal memory performance of 135 young adults, independent of demographic and vascular risk factors. Repeated multiple analyses of variances using cognitive measures by function as dependent variables revealed that worse glucose regulators showed poorer verbal memory performance compared to better glucose regulators, with the performance of average glucose regulators falling in between. There was no effect of solution nor did gender interact with glucose regulation. Although worse regulators showed evidence of hyperinsulinemia, glucoregulatory indices calculated on the basis of insulin levels or fasting glucose levels were less sensitive to cognitive variability relative to indices based on evoked glucose levels. Cardiovascular risk factors were indeed associated with hyperinsulinemia, however, these did not predict cognitive performance in this young group. These results were discussed in light of medial temporal lobe functions, including encoding and retrieval of information, and appear to be mediated by changes in lipid metabolism, insulin receptor distribution and function, and/or genetic susceptibility.

Quality of Life

description: Quality of life (QOL) is a concept that has received considerable attention as an outcome in the field of rehabilitation. Given that QOL can be affected by a myriad of factors, including one’s physical health, it is highly relevant for persons with chronic illnesses and disabilities (CID). Research suggests that chronic health is associated with wide-ranging symptomology and consequently, restricted functioning which in turn, negatively impact life satisfaction and QOL. To date, few studies have comprehensively examined QOL in African Americans with chronic health conditions. To address the gap in the literature, application of theoretical models that examine the relationship between biopsychosocial factors and QOL for African Americans with chronic health conditions is necessary.
description: The purpose of this study was to utilize the World Health Organization’s International Classification of Functioning, Disability, and Health (ICF) model as a framework to predict QOL in African Americans with chronic health conditions. Hierarchical regression analysis was used to assess the contribution of each individual ICF construct, to QOL. Results from the hierarchical regression analysis suggest that environmental influences (e.g., social stigma, social discrimination), personal characteristics (e.g., hope, coping style, resilience), activity (e.g., activity limitations) and community integration (e.g., numbers of hours worked) accounted for 62% of the variance in QOL of African Americans with chronic health conditions. Evidence-based interventions focused on enhancing hope and style of coping while reducing the effects of social stigma and discrimination are likely to increase QOL outcomes for African Americans with chronic health conditions.

description: Background. Injecting drugs safely almost always includes the presence of one’s social network, especially for the prevention of overdose. Yet, the systematic analysis of users’ social networks has yet to be established as a focal method in harm reduction research, and interventions. Methods. This study draws from 200 interviews with persons who inject drugs recruited from North America’s first sanctioned supervised injection facility and a drug user’s advocacy group. Respondents were asked about the individuals they personally considered as facilitators of harm reduction, and the relations between them. Collectively, these 200 respondents provided over 900 individuals whom they considered as members of their harm reduction network. The aim was to locate individuals that would potentially make the network denser (harm reduction champions) and users that were situated in the “periphery” of the network, and in practice, further away from the harm reduction core. Results. Results found that 63 individuals formed the “core” of the harm reduction network, collectively reaching approximately 70% of individuals in the network. We also uncovered 31 individuals that acted as “articulation points”– these individuals were not as connected, but were more effective at reaching peripheral individuals. Conclusion. The PWIDs we sampled were surrounded by a relatively rich harm reduction network, but the network approach showed that only a minority of individuals were true harm reduction “champions”. Recruitment of a combination of well-connected harm reduction champions, and strategically connected articulation points, would be most effective in planning network interventions that encourage harm reduction behaviors among this population.
Methods for total drug and related substances in pindolol.

Subjects: subject: Chemistry, Analytical.

description: A liquid chromatographic method for the assay of pindolol and related compounds in the bulk drug was developed. The method resolves six known and several unknown impurities from the drug and each other using a nitrile column, a mobile phase composed of acetonitrile-sodium acetate buffer (35:65), and a UV detector set at 219 nm. Minimum quantifiable amounts of impurities are 0.02% or less relative to the drug. Ten lots of pindolol raw material were evaluated for purity and drug content. Total levels of impurities in these samples, quantitated against pindolol, ranged from about 0.03% to 0.24%. Assay results were within the range of 98.5% to 101.5%.
