Ideas for rent: an overview of markets for technology
No full textThis article surveys some of the recent literature on technology markets, and summarizes its main issues and insights. We structure our analysis in three parts: the supply and demand of technology; the factors that condition the formation and growth of technology markets; industry structure and dynamic issues. In addition, we summarize some of the studies that have tried to document the size and growth of these markets. We find that the literature has focused mainly on the supply of technology, but several other aspects of these markets remain under-studied, including the demand for external technology, the role of uncertainty in technology markets, and the dynamic interaction between industry structure and the market for technology. Understanding these will illuminate whether markets for technology will continue to grow or remained confined to pockets of the economy. Copyright 2010 The Author 2010.

Metrics for analytics and visualization of big data with applications to activity recognition
No full textActivity recognition systems detect the hidden actions of an agent from sensor measurements made on the agents' actions and the environmental conditions. For such systems, metrics are important for both performance evaluation and visualization purposes. In this thesis, such metrics are developed and illustrated. For human activity recognition datasets, a reporting structure is described to visualize the metrics in a systematic manner. The other contribution of this thesis is to describe a visualization tool for estimating the orientation (attitude) of a rigid body from streaming motion sensor (accelerometer and gyroscope) data. A feedback particle filter (FPF) is implemented algorithmically to solve the estimation problem.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-05-01The student, Rohan Arora, accepted the attached license on 2016-04-25 at 10:47.The student, Rohan Arora, submitted this Thesis for approval on 2016-04-25 at 10:48.This Thesis was approved for publication on 2016-04-27 at 15:05.DSpace SAF Submission Ingestion Package generated from Vireo submission #9459 on 2016-07-07 at 14:17:57Made available in DSpace on 2016-07-07T21:18:02Z (GMT).

Burnout and job satisfaction in orthopaedics
No full textAbstract â Burnout among Australian orthopaedic trainees and the factors associated with it
Aim: To study burnout prevalence and associated factors among Australian orthopaedic trainees.
Method: We conducted a nationwide cross-sectional observational study using a 32-question survey consisting of a self-developed item set of 10 questions and a 22-question validated instrument (Maslach Burnout Inventory â Human Services Survey) to assess burnout. The survey was emailed to 236 orthopaedic registrar members of the Australian Orthopaedic Association.
Results: 51 trainees completed the survey, yielding a response rate of 22%. Burnout prevalence among orthopaedic trainees was high (52%) despite high career satisfaction (89%). 55% of trainees were dissatisfied with their work-life balance. Burned out trainees were more likely to be dissatisfied with their choice of orthopaedics as a career (p=0.004) and with their work-balance (p=0.021) compared with their non-burned out counterparts. Females were more likely to be burned out than males and non-married trainees more than married trainees, although these associations were not significant. There was no observed trend for burnout with relation to seniority in the training program.
Discussion: Burnout prevalence among Australian orthopaedic trainees is high despite high career satisfaction. There may be a role for active interventions aimed at combating burnout and improving work-life balance among orthopaedic trainees.
Abstract â Job satisfaction among Australian orthopaedic surgeons and the factors associated with it
Introduction: High job satisfaction has positive outcomes for patients, health institutions and surgeons. There has been no research into job satisfaction primarily among Australian orthopaedic surgeons and its associated factors. The aim of this study was to assess job satisfaction and associated factors among Australian orthopaedic surgeons.
Method: We conducted a nationwide survey using a 24-item questionnaire consisting of a self-developed item set of 14 questions and a 10-question modified version of Warr-Cook-Wall Job Satisfaction instrument to assess job satisfaction. The survey was emailed to 1393 orthopaedic surgeon members of the Australian Orthopaedic Association.
Results: 217 surgeons completed the survey, yielding a response rate of 16%. 88% of responders were either very satisfied or moderately satisfied with their jobs. 20% of responders were dissatisfied with their hours of work and a further 15% of responders were dissatisfied with the level of recognition they get for good work. Surgeons with higher job satisfaction were less likely to feel that workload severely compromised their personal/family life (p<0.001), had better perceived self-health (p=0.04), and were less likely to have considered leaving orthopaedic surgery in the last year (p<0.001).
Discussion: Australian orthopaedic surgeons are highly satisfied with their jobs. There may be a role for active interventions aimed at improving hours of work and work-life balance
Glyceryl trinitrate patches—An alternative treatment for shoulder impingement syndrome
No full textSummaryTransdermal glyceryl trinitrate patches have been investigated as an alternative therapeutic intervention for a range of tendinopathies, due to the ease of titration of dosage and the ease of their application. Glyceryl trinitrate has been inferred to reduce pain and inflammation secondary to their nitric oxide-producing action. Shoulder impingement syndrome is a soft tissue condition that manifests as anterior shoulder pain, weakness, and difficulty in daily activities. This review will evaluate the efficacy of glyceryl trinitrate patches in treating a variety of rotator cuff tendinopathies related to shoulder impingement, based on human and animal trials, and suggest its practical application in future trials and management
First generation Asian immigrants and mental health treatment
No full textAny first generation immigrant has a hard time assimilating to life in a new country, and this holds true for the Asian population and their mental health (Arora et al., 2020). This project focused on what impacts mental health of first generation Asian immigrants.Research presentationFaculty Mentor: Dr. Kathy Andrese
A novel and simple classification for ligamentum teres pathology based on joint hypermobility
No full textTowards automated classification of fine-art painting style: a comparative study
No full textThis thesis presents a comparative study of different classification methodologies for the task of fine-art genre classification. The problem of painting classification involves classifying new unknown paintings among different art genres. Two-level comparative study is performed for this classification problem. The first level reviews the performance of discriminative vs. generative models while the second level touches the features aspect of the paintings and compares Semantic-level features vs low-level and intermediate-level features present in the painting. Three models are studied and compared, namely - 1) A Discriminative model using a Bag-of-Words (BoW) approach; 2) A Generative model using BoW; 3) Discriminative model using Semantic-level features. Various experiments and techniques like Bag of Words model, Topic models and Classeme features are employed to get insights into potential of these automatic classification techniques for painting styles.M.S.Includes bibliographical referencesby Ravneet Singh Aror

Role of nutritional supplementation in elderly patients with hip fractures
No full textAbstractDue to the ageing population there is an increasing incidence of hip fractures in the elderly. Oral nutritional supplements are being widely used to improve clinical outcomes and mortality post-hip fractures. The aim of this study was to review the available literature on the effects of oral nutritional supplements on elderly patients with hip fractures. A search of EMBASE (1988–present) and MEDLINE (1946–present) with the search terms: “nutritional supplement” AND “hip fracture”; “nutritional supplement” AND “femoral neck fracture”; “nutritional supplement” AND “intertrochanteric fracture”; “nutritional supplement” AND “subcapital fracture”; “hip fracture” AND “vitamin supplement”; “hip fracture” AND “protein supplement”; “hip fracture” AND “nutrient supplement” was carried out. Additionally, the reference lists of articles were searched for relevant areas of study. Few studies showed that oral nutritional supplementation led to a more positive clinical outcome amongst elderly patients suffering hip fractures. Most studies found little or nil positive results. Thus, the role of oral nutritional supplementation on post-hip fracture mortality, infection/complication rates, and hospitalisation/rehabilitation time amongst elderly patients is unclear. There is a need for a broader, randomised, placebo-controlled clinical trial on the effect of oral nutritional supplements and particularly on the supplements used commonly
