Palliative care in undergraduate curricula : Results of a national scoping study

Background: We wished to explore the ways in which palliative care is included in undergraduate health services curricula in Australia and the barriers to, and opportunities for, such inclusion. Methods: A scoping study of current Australian undergraduate health care curricula, using an email survey of deans (or equivalent) of health faculties was designed utilising all Australian undergraduate courses that prepare medicine, nursing and allied health professionals for entry to practice. Participants were deans or faculty heads from health and related faculties which offered courses relevant to the project, identified from the Australian Government Department of Education, Science and Training website. Sixty-two deans (or equivalent) from 41 Australian universities were surveyed. A total of 42 completed surveys were returned (68% of deans). Main outcome measures were total hours, content, teaching and learning strategies and resources for palliative care education in undergraduate curricula; perceived gaps, barriers, and opportunities to support the inclusion of palliative care education in undergraduate curricula. Results: Forty-five percent of respondents reported the content of current curricula reflected the palliative approach to a large degree. More than half of the respondents reported that their course had palliative care components integrated to a minor degree and a further third to a moderate degree. The number of hours dedicated to palliative care and teaching and learning strategies varied across all respondents, although there was a high degree of commonality in content areas taught. Conclusion: Current Australian undergraduate courses vary widely in the nature and extent to which they provide education in palliative care.

Measuring transit service reliability using data from web-based transit user survey : a case study at Brisbane, Australia

This paper reports an empirical study on measuring transit service reliability using the data from a Web-based passenger survey on a major transit corridor in Brisbane, Australia. After an introduction of transit service reliability measures, the paper presents the results from the case study including study area, data collection, and reliability measures obtained. This includes data exploration of boarding/arrival lateness, in-vehicle time variation, waiting time variation, and headway adherence. Impacts of peak-period effects and separate operation on service reliability are examined. Relationships between transit service characteristics and passenger waiting time are also discussed. A summary of key findings and an agenda of future research are offered in conclusions.

Challenges in the supervisory boardroom : an exploratory study in the Netherlands

As a consequence of recent corporate governance reforms, the work of supervisory board members in the Dutch two-tier system has become more complex. The objectives of this study are to gain more insight in the current challenges that supervisory board members face and assess whether they are well-equipped to manage them. Based on a combination of an analysis of self-assessment reports, a web-based survey and semi-structured interviews, we conclude that the major challenges of supervisory board members lie in the field of interaction and collaboration with executives. Distinct ‘challenge areas’ were relatively often perceived as problematic as well as important, highlighting the need to improve the current functioning of boards. With regard to the skills that are present on supervisory boards, we find that individual qualities, like integrity, professionalism and knowledge, are better recognized than collective qualities for the supervisory board as a whole. In particular, openness and honesty are seen as important, but often lacking. The paper highlights several implications for scholars and practitioners.

High performance additive manufactured scaffolds for bone tissue engineering application

This study demonstrates the feasibility of additive manufactured poly(3-caprolactone)/silanized tricalcium phosphate (PCL/TCP(Si)) scaffolds coated with carbonated hydroxyapatite (CHA)-gelatin composite for bone tissue engineering. In order to reinforce PCL/TCP scaffolds to match the mechanical properties of cancellous bone, TCP has been modified with 3-glycidoxypropyl trimethoxysilane (GPTMS) and incorporated into PCL to synthesize a PCL/TCP(Si) composite. The successful modification is confirmed by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) analysis. Additive manufactured PCL/TCP(Si) scaffolds have been fabricated using a screw extrusion system (SES). Compression testing demonstrates that both the compressive modulus and compressive yield strength of the developed PCL/TCP(Si) scaffolds fall within the lower ranges of mechanical properties for cancellous bone, with a compressive modulus and compressive yield strength of 6.0 times and 2.3 times of those of PCL/TCP scaffolds, respectively. To enhance the osteoconductive property of the developed PCL/TCP(Si) scaffolds, a CHA-gelatin composite has been coated onto the scaffolds via a biomimetic co-precipitation process, which is verified by using scanning electron microscopy (SEM) and XPS. Confocal laser microscopy and SEM images reveal a most uniform distribution of porcine bone marrow stromal cells (BMSCs) and cellsheet accumulation on the CHA-gelatin composite coated PCL/TCP(Si) scaffolds. The proliferation rate of BMSCs on the CHA-gelatin composite coated PCL/TCP(Si) scaffolds is 2.0 and 1.4 times higher compared to PCL/TCP(Si) and CHA coated PCL/TCP(Si) scaffolds, respectively, by day 10. Furthermore, the reverse transcription polymerase chain reaction (RT-PCR) and western blot analyses reveal that CHA-gelatin composite coated PCL/TCP(Si) scaffolds stimulate osteogenic differentiation of BMSCs the most compared to the other scaffolds. In vitro results of SEM, confocal microscopy and proliferation rate also show that there is no detrimental effect of GPTMS modification on biocompatibility of the scaffolds.

Using Fiber Bragg Grating (FBG) sensors to measure vertical displacements of bridges : a preliminary study

In many bridges, vertical displacements are the most relevant parameter for monitoring in the both short and long term. However, it is difficult to measure vertical displacements of bridges and yet they are among the most important indicators of structural behaviour. Therefore, it prompts a need to develop a simple, inexpensive and yet more practical method to measure vertical displacements of bridges. With the development of fiber-optics technologies, fiber Bragg grating (FBG) sensors have been widely used in structural health monitoring. The advantages of these sensors over the conventional sensors include multiplexing capabilities, high sample rate, small size and electro magnetic interference (EMI) immunity. In this paper, methods of vertical displacement measurements of bridges are first reviewed. Then, FBG technology is briefly introduced including principle, sensing system, characteristics and different types of FBG sensors. Finally, the methodology of vertical displacement measurements using FBG sensors is presented and a trial test is described. It is concluded that using FBG sensors is feasible to measure vertical displacements of bridges. This method can be used to understand global behaviour of bridge‘s span and can further develop for structural health monitoring techniques such as damage detection.
