Degree of contribution (DoC) feature selection algorithm for structural brain MRI volumetric features in depression detection

Accurate detection of depression at an individual level using structural magnetic resonance imaging (sMRI) remains a challenge. Brain volumetric changes at a structural level appear to have importance in depression biomarkers studies. An automated algorithm is developed to select brain sMRI volumetric features for the detection of depression.

Evaluation of postgraduate critical care nursing students' attitudes to, and engagement with, Team-Based Learning: a descriptive study

The aim of this study was to evaluate postgraduate critical care nursing students' attitudes to, and engagement with, Team-Based Learning (TBL).

Portfolio careers for medical graduates: implications for postgraduate training and workforce planning.

Portfolio careers in medicine can be defined as significant involvement in one or more portfolios of activity beyond a practitioner's primary clinical role, either concurrently or in sequence. Portfolio occupations may include medical education, research, administration, legal medicine, the arts, engineering, business and consulting, leadership, politics and entrepreneurship. Despite significant interest among junior doctors, portfolios are poorly integrated with prevocational and speciality training programs in Australia. The present paper seeks to explore this issue. More formal systems for portfolio careers in Australia have the potential to increase job satisfaction, flexibility and retention, as well as diversify trainee skill sets. Although there are numerous benefits from involvement in portfolio careers, there are also risks to the trainee, employing health service and workforce modelling. Formalising pathways to portfolio careers relies on assessing stakeholder interest, enhancing flexibility in training programs, developing support programs, mentorship and coaching schemes and improving support structures in health services.

Evaluation of a filmed clinical scenario as a teaching resource for an introductory pharmacology unit for undergraduate health students: A pilot study.

BACKGROUND: Simulation is frequently being used as a learning and teaching resource for both undergraduate and postgraduate students, however reporting of the effectiveness of simulation particularly within the pharmacology context is scant. OBJECTIVES: The aim of this pilot study was to evaluate a filmed simulated pharmacological clinical scenario as a teaching resource in an undergraduate pharmacological unit. DESIGN: Pilot cross-sectional quantitative survey. SETTING: An Australian university. PARTICIPANTS: 32 undergraduate students completing a healthcare degree including nursing, midwifery, clinical science, health science, naturopathy, and osteopathy. METHODS: As a part of an undergraduate online pharmacology unit, students were required to watch a filmed simulated pharmacological clinical scenario. To evaluate student learning, a measurement instrument developed from Bloom's cognitive domains (knowledge, comprehension, application, analysis, synthesis and evaluation) was employed to assess pharmacological knowledge conceptualisation and knowledge application within the following fields: medication errors; medication adverse effects; medication interactions; and, general pharmacology. RESULTS: The majority of participants were enrolled in an undergraduate nursing or midwifery programme (72%). Results demonstrated that the majority of nursing and midwifery students (56.52%) found the teaching resource complementary or more useful compared to a lecture although less so compared to a tutorial. Students' self-assessment of learning according to Bloom's cognitive domains indicated that the filmed scenario was a valuable learning tool. Analysis of variance indicated that health science students reported higher levels of learning compared to midwifery and nursing. CONCLUSION: Students' self-report of the learning benefits of a filmed simulated clinical scenario as a teaching resource suggest enhanced critical thinking skills and knowledge conceptualisation regarding pharmacology, in addition to being useful and complementary to other teaching and learning methods.

Life-context interactions and their contributions to postgraduate distance learning

 This thesis explores the learning contributions of interactions between distance learners and other people in their lives about the academic content of their studies. It proposes new ways of conceptualising learning and learner interaction modes in distance education, and a new approach to distance education program design.

In this paper, we propose an algorihm for conneced p-percent coverage probem in Wireless Sensor Networks(WSNs) to improve the over netork life time. In this work, we invstigae the p-pernt coverage problem(PCP) in WSNs which require % of n area should be monitored correctl and to find ou ny additional requirements of the connec p-percent coverge prom. We prose pDCDS algorith which is a learnin autmaton basd algorithm fr PCP pDCDS is a Degreconsained Connected Domining Se based algoithm whch detect the minimum numbe of des to monitor an area. The simulation results demonstrate hat pDCDS can remarkably improve the network lifetime.

Examining the effect of time constraint on the online mastery learning approach towards improving postgraduate students' achievement

Time control plays a critical role within the online mastery learning (OML) approach. This paper examines the two commonly implemented mastery learning strategies – personalised system of instructions and learning for mastery (LFM) – by focusing on what occurs when there is an instructional time constraint. Using a large data set from a postgraduate finance course offered at an Australian university, we explore students' online quiz-completion patterns, then empirically investigate whether the imposition of an instructional time constraint in the OML approach has an impact on their final-examination performance. Our results suggest that the LFM strategy with an instructional time constraint has a positive impact on students' learning behaviour and contributes to better overall academic performance. Further, our findings suggest that facilitators should be encouraged to implement an instructional time constraint when adopting an OML approach.

A case study on critical reflection: a Chinese postgraduate in Australia

Critical reflection (CR) is at the core of postgraduate studies in c, and students from Asia in general, and from c in particular, often find the concept challenging when reading texts or applying it to written texts in English. This study reports on a case study of a Chinese postgraduate student in Australia. It explores the challenges and obstacles in terms of CR that she faced while completing her subjects in a TESOL program in Australia. These challenges were articulated in a semi-structured interview conducted with the student. Challenges include English language proficiency, lack of focus on writing in China where there is a lot of emphasis on memorisation, different systems of conceptualisation of topics in Chinese and English, and limited freedom of expression which is expressed as ‘authoritative’ control in the Chinese educational context.

Development, implementation and evaluation of an interprofessional graduate program for nursing-paramedicine double-degree graduates

Over the past decade, several Australian universities have offered a double degree in nursing and paramedicine. Mainstream employment models that facilitate integrated graduate practice in both nursing and paramedicine are currently lacking. The aim of the present study was to detail the development of the Interprofessional Graduate Program (IPG), the industrial and professional issues that required solutions, outcomes from the first pilot IPG group and future directions. The IPG was an 18-month program during which participants rotated between graduate nursing experience in emergency nursing at Northern Health, Melbourne, Australia and graduate paramedic experience with Ambulance Victoria. The first IPG with 10 participants ran from January 2011 to August 2012. A survey completed by nine of the 10 participants in March 2014 showed that all nine participants nominated Ambulance Victoria as their main employer and five participants were working casual shifts in nursing. Alternative graduate programs that span two health disciplines are feasible but hampered by rigid industrial relations structures and professional ideologies. Despite a 'purpose built' graduate program that spanned two disciplines, traditional organisational structures still hamper double-degree graduates using all of skills to full capacity, and force the selection of one dominant profession.

Colourful language: researching architects' knowledge and use of colour

The development of architectural materials and technology is transforming the colour palettes and identities of cities by juxtaposing or replacing vernacular colours with global and often contextually meaningless colours. As Built Environment designers have significant roles in determining city colourscapes, it might be expected that th ese professionals have considerable knowledge. However, there is largely an absence of colour training in the majority of built environment degree programs. While colour has been studied in a broad range of disciplines, very few studies have focussed on architecture and even less on colour in architectural education. This paper reports on the early findings of research into what informs architect’s understanding and use of colour. Data was analysed from a survey of 33 practicing architects, academics and postgraduate students from Melbourne, Australia. The findings indicate that built environment designers see the need for increasing their colour knowledge. In line with previous studies, there was no evidence of correlations between gender and age, but findings suggest cultural differences in the level of colour education depending on country of architectural study. The wider research that this study is a part of ultimately aims to inform education around the use of colour in the built environment.
