An E-Learning Approach to the Prevention of Venous Thromboembolism: An Educational and Human Factors Study
No full textThe research contained within this thesis submitted for the degree of Doctor of Philosophy in Medicine investigates the role of e-learning in improving knowledge mastery around venous thromboemolism prophylaxis among medical students. Following an exhaustive literature review of venous thromboembolism epidemiology, pathology and prevention, educational theory, e-learning techniques and the delivery of education about venous thromoboembolism to medical students, the key deficiencies in our understanding of this disease were identified. We found multiple small cohort studies about the use of e-learning in medical education, but a paucity of randomised controlled trial data surrounding the use of e-learning platforms, and limited information regarding the role of instructional erongomics in e-learning delivery for medical education. Conducting a randomised controlled educational trial may determine the utility of elearning for improving student’s knowledge of venous thromboembolism prophylaxis. This investigation commenced with the development of e-learning modules in surgery, medicine, oncology, obstetrics & gynaecology and orthopaedic surgery. Two further assessment modules were also developed; one to measure baseline knowledge about venous thromboembolism prophylaxis, and one to measure postintervention effect. A randomised controlled trial was conducted to measure the effect of e-learning at improving knowledge of thromboprophyaxis guidelines. Students randomised to use the e-learning module did not demonstrate any improvement in knowledge surrounding VTE prophylaxis, either in comparison to the control group, or in comparison to their own baseline scores. Interestingly, however, students demonstrated a statistically significant improvement in knowledge when they were re-tested six months after finishing the e-learning program. This result may demonstrate that e-learning is a useful tool in a blended learning model of teaching, however, there is a possibility that confounding factors had played a role. We conducted a subgroup analysis to determine whether performance in certain cases within the e-learning module were predictive of final outcome, and whether time spent on each case was associated with final performance. We demonstrated that performance in the eMedici VTE Prophylaxis Module appeared to be associated with performance in areas of medicine in which students had prior experience, or were currently rotating. Finally, we were interested in examining ergononic factors related to the use of elearning material, particularly as one member of the group had published similar research examining the use of computer-aided learning when material was presented on CD-ROM. There is limited reporting on ergonomic data in the medical education literature, and we felt that this study may also help explore the possible causes of the results of the randomised controlled trial. This study demonstrated the importance of usability testing in designing online medical education resources, and suggests the importance of supporting online learning through the provision of physical learning spaces and infrastructure within the clinical setting.Thesis (Ph.D.) -- University of Adelaide, Adelaide Medical School, 201

No full textFinance Constraints and Inventory Investment: Empirical Tests with Panel Data
No full textThe author empirically tests two aspects of the interaction between financial variables and inventory investment: negative cash flow and finance constraints due to asymmetric information. This is one of the first studies of inventory investment and finance constraints using Canadian data. A sample of Canadian manufacturing firms over the period 1992Q2-1999Q4 is split into subsamples based on age, bond rating, and size to reflect expected differences in degrees of asymmetric information problems. The findings are consistent with a model in which inventory investment is a U-shaped function of cash flow. Higher degrees of information asymmetry do no appear to generate differences in the sensitivity of inventory investment to cash flow during the sample period.information asymmetries, finance constraints, liquidity constraints, inventories, inventory investment, Povel and Raith model, negative cash flow,
Walking, Wandering, Strolling: Approaching Hamburg¿s HafenCity
No full textDass Gehen nicht nur eine alltägliche Notwendigkeit ist, sondern noch viel mehr Potenzial hat, wusste man bereits in der Antike. Seit damals gab es zahlreiche Auseinandersetzungen mit diesem Thema, unter anderem in Architektur und Stadtplanung. Als Lucius Burckhardt schließlich in den 1980er Jahren die Spaziergangswissenschaft (auch »Promenadologie«) begründete, setzte er einen neuen Meilenstein. Themen wie Erwartung, Landschaft, Selektionsmechanismen, Raumsequenzen und vieles mehr wurden dabei wichtig. Diese Arbeit beschäftigt sich mit dem Spazierengehen in der Stadt. Dabei sind nicht nur die geschichtlichen Hintergründe relevant, sondern auch Aspekte wie Semiotik und Wahrnehmung. Um den Einfluss der Annäherung auf die Wahrnehmung eines Ziels zu untersuchen, begibt sich die Autorin schließlich im Selbstversuch auf zwei Spaziergänge durch Hamburg. Eine anschließende Analyse macht deutlich, wie vielfältig die Einflüsse im Zuge solcher Spaziergänge sind und welches Potenzial demnach die Spaziergangswissenschaft als Planungsmethode aufweist.Even in ancient times it was known that walking is not just a daily necessity, but contains a lot more potential. Since then, a lot of people, including architects and urbanists, devoted themselves to the study of this topic. Lucius Burckhardt set a milestone in the 1980s when he founded the new science of “strollology”. Topics like expectation, landscape, selection mechanisms and space sequences turned out to be central to this field. This thesis focuses on urban strolling, considering not only the historical roots and its development over time, but also different methodological aspects such as semiotics and perception. To analyse the influence exerted upon the perception of a destination by the specific approach taken to get there, the author finally conducts a self-experiment by going for two strolls through Hamburg. The subsequent analysis shows the large variety of influencing factors during such strolls and also makes the case for the great potential of using strollology as a planning tool
Perspectives and insights of critical care clinicians, patients and families from culturally and linguistically diverse backgrounds around end-of-life care in an ICU: a scoping review protocol
No full textObjective Protocol to explore what is known about communication between critical care providers and patients and families from culturally and linguistically diverse backgrounds (defined as people who are either from minority ethnic groups, non-English-speaking backgrounds who may have diverse cultural, linguistic, spiritual and religious affiliations and opinions) about death, dying, end-of-life care and organ donation in the intensive care unit (ICU).Introduction Patients from culturally and linguistically diverse backgrounds experience barriers to optimised care when admitted to the ICU. These barriers appear to derive from differences in language, cultural, societal and ethical expectations between patients, their families and healthcare professionals. These barriers may significantly impact the delivery of end-of-life care to patients from culturally and linguistically diverse backgrounds. Therefore, this has the potential for inadequate management of medical, psychological and existential distress.Inclusion criteria Studies of all designs reporting for adult (age ≥18 years) patients and family members from culturally and linguistically diverse backgrounds at end-of-life in the ICU setting will be included. Studies that report results for patients aged <18 years or that are based outside the ICU will be excluded.Methods Relevant sources will be retrieved, and their citation details will be imported into the Joanna Briggs Institute (JBI) System for the Unified Management, Assessment and Review of Information. This scoping review was guided by the JBI methodology for scoping reviews and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. A systematic search was conducted in EBSCOhost, Web of Science, PubMed Central and SciELO, OVID Medline, CINAHL, and Scopus, limited to English-language publications, without date limitation. Key study characteristics and findings will be extracted using a data extraction tool developed by the reviewers. Anticipating heterogeneous study designs, findings will be presented as a thematic synthesis.Ethics and dissemination This is a protocol for a scoping review, formal ethics approval from the Human Research Ethics Committee (HREC) of the Local Health Network will be obtained for research projects that could potentially stem from this review and will then be subsequently disseminated through proper channels
