Combining vocational and higher education studies to provide dual parallel qualifications – an Australian case study

Developing academic relationships between vocational colleges and universities in Australia has been problematic, with exchanges between the two sectors limited to linear articulation and prescribed credit transfer. Whilst some very good examples of collaboration exist, the two sectors generally operate independently of each other. The isolation of the sectors has meant frustration for students and employers who want a flexible, collaborative model to meet changing industry needs. This paper reports upon a pilot project in construction management at a Melbourne university that attempted to address these needs. It demonstrates how over a five year period, HE students completed electives in practical units within the VET sector. The overwhelming success of the project meant that practical electives were embedded in the construction management programme in 2007 and this paper reports on the third, final phase of the project in 2009/10 which saw construction management students graduate with a dual qualification - both a vocational qualification and a university degree. Interviews conducted in this final phase reveal that students and industry want the benefits of a practical and theoretical qualification. The paper raises critical questions about educational pathways and suggests long-term implications for construction and tertiary education in Australia and internationally.
Hardness-assurance issues for lateral PNP bipolar junction transistors

The dose-rate dependence of gain degradation in lateral PNP transistors is even stronger than the dependence previously reported for NPN BJTs. In this work, several hardness-assurance approaches are examined and compared to experimental results obtained at low dose rates. The approaches considered include irradiation at high dose rates while at elevated temperature and high-dose-rate irradiation followed by annealing. The lateral PNP transistors continue to degrade during post-irradiation annealing, in sharp contrast to NPN devices studied previously. High-temperature conditions significantly increase the degradation during high-dose-rate irradiation, with the amount of degradation continuing to increase with temperature throughout the range studied here (up to 125/spl deg/C). The high-temperature degradation is nearly as great as that observed at very low dose rates, and is even greater when differences between /sup 60/Co and X-ray irradiation are accounted for. Since high-temperature irradiation has previously been shown to enhance the degradation in NPN transistors, this appears to be a promising hardness-assurance approach for bipolar integrated circuits. Based on these results, preliminary testing recommendations are discussed.
Modeling the cytotoxic t cell response

This work describes a computer model of the immune system's response to infection, specifically the cytotoxic T lymphocyte (CTL) response. CTLs play an important role in the control of infectious agents, and they are essential components of our defense against HIV, cancer, and other diseases of great public interest. Immunologists are interested in manipulating and enhancing the CTL response to these diseases, whether by vaccination or drug therapy, but the process can be difficult and ad hoc. A combination of animal experimentation, limited human testing, and simple mathematical models have been the primary sources of guidance in the efforts to address these diseases. Computer models provide an alternative strategy for exploring immune system therapies. Recently developed laboratory techniques that have revealed and quantified many aspects of CTL behavior provide an unprecedented opportunity to develop detailed models. The model used in this work integrates many of these new findings into a coherent system that simulates an immune response to viral infection. This model reproduces many of the phenomena seen in CTL responses but not captured by other mathematical or computer models and can be used to explore vaccination strategies. The value of modeling goes beyond simply making predictions. It allows one to perform experiments difficult, or even impossible, to perform in the laboratory. For example, in a computer model one can replicate experiments exactly or choose to allow stochastic fluctuations to influence the outcome. In biological systems, achieving this level of control is impossible. Model-building can also be used as a vehicle for hypothesis testing by formulating one's assumptions about a system's behavior as a model. If the model's behavior does not match real-world experimental results, the initial assumptions can be changed and a new model built. The model presented here is the result of a series of such choices.
Flam — A simultaneous source wide azimuth test

Summary A wide azimuth acquisition test was performed in the Gulf of Mexico where two sources out of four in total were fired simultaneously. All firing times were randomized within a small window to minimize the interference from the near simultaneous source as well as minimizing the effect of remnant coherent noise from the preceding shot. Results show direct comparisons between a conventional wide azimuth acquisition and the simultaneous source method as well as decimated results which represent apple to apple comparison in terms of fold and shot positions. The simultaneous source method has the potential to significantly improve wide azimuth acquisition as well as other acquisition geometries.
Working Time Flexibilities: A Paradox in Call Centres?

Call centres are a source of job growth in many parts of the world. Jobs in call centres are a manifestation of the opportunities offered by ICT, together with the internal restructuring of organisations, to reduce costs and to achieve efficiencies. Extensive research has been conducted on the labour process in call centres, with findings suggesting that the work is demanding and high-pressured, entailing continuous operations with shift work being the norm, repetition and extensive monitoring and control. Moreover, call centres often have many female operatives, linked to non-standard work arrangements and the provision of emotional skills. Two features of call centres that are generally understated in the literature are their flat organisational structures and the use of team structures as a form of work organisation. There are often formal and informal mechanisms that could support flexible working arrangements, especially in the context of work-life balance issues. In this article we examine the impact of call centre work on worklife balance. Given the evidence of a high pressure work environment, we explore the types of working time arrangements in call centres, how working hours are determined, and the impact of these hours on work-life balance. Findings derived from a survey of 500 call centre operatives across 10 call centre workplaces and focus group interviews suggest that, despite the intensive and regulated work regimes that there is flexibility available in terms of adjusting working time arrangements to support non work responsibilities. A reconciliation of these developments is considered.
Evaluating Outcome Prediction Models in Endovascular Stroke Treatment Using Baseline, Treatment, and Posttreatment Variables

Statistical models to predict outcomes after endovascular therapy for acute ischemic stroke often incorporate baseline (pretreatment) variables only. We assessed the performance of stroke outcome prediction models for endovascular therapy in stroke in an iterative fashion using baseline, treatment‐related, and posttreatment variables. Data from the ESCAPE‐NA1 (Safety and Efficacy of Nerinetide [NA‐1] in Subjects Undergoing Endovascular Thrombectomy for Stroke) trial were used to build 4 outcome prediction models using multivariable logistic regression: model 1 included baseline variables available before treatment decision making, model 2 included additional treatment‐related variables, model 3 additional posttreatment variables that become available early (within 24–48 hours), and model 4 later (beyond 48 hours) after endovascular therapy. The primary outcome was functional independence (90‐day Modified Rankin Scale score 0–2). Model performance was compared using the area under the receiver operating characteristic curve (AUC). Shapley values were used to determine marginal contributions of variables to outcome variance in the regression models. Among 1105 patients, functional independence was achieved by 666 (60.3%). When using baseline variables only (model 1), the AUC was 0.74 (95% CI, 0.71–0.77); this iteratively improved when treatment and posttreatment variables were added to the models (model 2: AUC, 0.77; 95% CI, 0.74–0.80; model 3: AUC, 0.80; 95% CI, 0.77–0.83; model 4: AUC, 0.82; 95% CI, 0.79–0.85). With baseline variables alone, 26% of patients who achieved functional independence were erroneously classified as not achieving functional independence. Even with the most comprehensive model, 19.8% of patients were misclassified as such. Patient age contributed most to outcome variance (Shapley value, 0.28), followed by severe adverse events including pneumonia (0.16) and intracranial hemorrhage at 24‐hours imaging (0.13). A substantial contribution to outcomes after endovascular therapy comes from factors unrelated to currently collected baseline patient variables. One‐fifth of patients achieving functional independence were misclassified as not achieving independence, even with the most comprehensive model. Our findings suggest that the achievable accuracy of current outcome prediction models is limited, and caution should be used when applying them in clinical practice.
SNR enhancement of OTDR using biorthogonal codes and generalized inverses

We propose and experimentally demonstrate a novel technique which significantly improves the performance of optical time-domain reflectometry (OTDR). Applying biorthogonal codes and Moore-Penrose generalized inverses, a signal-to-noise ratio enhancement of up to 9.04 dB, namely a coding gain, was achieved over conventional OTDR.
High density organic flip chip package substrate technology

High performance logic ICs are rapidly migrating from peripheral bonded package configurations to area array, flip chip configurations. Total die I/O is exploding from <800 pins to more than 3500 pins with little abatement in the rate of increase in total silicon area. Traditional flip chip package substrate technologies, such as co-fired ceramic, are not able to adequately support this growing industry trend due to inherent limitations in thermal cycling reliability of the level 2 interface, density, electrical performance, and cost of use. A new, cost effective, organic flip chip package substrate technology has been developed, prototyped, qualified, and is being ramped into production. This laminated technology uses a nonwoven polytetrafluoroethylene (PTFE) composite dielectric combined with a fabrication technology that has produced the highest density organic substrates yet disclosed. The technology has been used to fabricate packages for die up to 18.5 mm by 18.5 mm with more than 3800 total I/O. Body sizes of up to 45 mm have been fabricated. In this paper, we will discuss the materials of construction, process technology, reliability characterization, thermo-mechanical characterization, and electrical performance of various cross-sections using this new technology.
Rationale, Design and Methods of the Prospective Record of the Use of Dabigatran in Patients with Acute Stroke or TIA (PRODAST) Study

Background The optimal timing of anticoagulation following acute ischaemic stroke or TIA in patients with atrial fibrillation (AF) is a frequent challenge. Early initiation of anticoagulation can reduce the risk for recurrent ischaemic events, but may lead to an increased risk for intracerebral haemorrhage. Aim The Prospective Record of the Use of Dabigatran in Patients with Acute Stroke or TIA (PRODAST) study was initiated to investigate outcome events under antithrombotic therapy after ischaemic stroke or TIA in patients with AF. The main objective is to compare the three-month rates of major haemorrhagic events between early (≤ 7 days) versus late (> 7 days) administration of dabigatran or treatment with vitamin-K antagonists started at any time. Occurrences of ischaemic and major haemorrhagic events will be evaluated to determine the optimal time point for initiation or resumption of anticoagulation. Design and Methods PRODAST is a prospective, multicenter, observational, non-interventional post-authorization safety study. 10,000 patients with recent (≤ 1 week from index event) ischaemic stroke or TIA and non-valvular AF were recruited at 86 German sites starting in July 2015. The observational plan includes a baseline visit, documentation of data during hospitalization and a telephone-based, central follow-up at three months after the index event. The primary endpoint is the major bleeding rate within three months. Secondary endpoints include rates of recurrent ischaemic or haemorrhagic stroke, TIA, systemic embolism, myocardial infarction and death. Summary PRODAST will provide important real-world data on safety and efficacy of antithrombotic therapy after acute stroke and TIA in patients with AF.
Rising to the Challenge of COVID-19: Pivoting to Online and Project-Based Physiotherapy Student Placements in Contemporary Professional Settings

Online and project-based student placements in sport and corporate settings were incorporated within the Macquarie University Doctor of Physiotherapy following the restriction of face-to-face delivery during the COVID-19 pandemic. This study explores student and educator perceptions of these placements, and analyses student performance results to provide future recommendations. The mixed-methods design included a student survey, semi-structured educator interviews and quantitative analysis of student assessment performance comparing 2020 to 2018/2019 cohorts. Quantitative survey data were described, with proportional differences between groups analysed. Open-ended survey responses and interview transcripts were thematically analysed, and integration of all results was performed. Themes derived from 24 student surveys highlighted that the learning experiences and skills required for online and project-based placements were varied and valuable. Analysis of 176 students’ performance showed differences between performance and applicability of assessment items in 2020 placements in comparison to previous years, although all students met performance requirements. Analysis of eight educator interviews identified that online and project-based placements changed experiences for all stakeholders and highlighted the need for enhanced educator and student communication and organisation for the placement to be successful. Online and project-based placements were considered a better reflection of contemporary work practices, producing valuable deliverables to the business. Three final integrated themes were identified regarding online and project-based elements of placements: learning experiences of students differed, skills for students and educators differed, and placements were representative of real-world work. A hybrid approach that incorporates both online and onsite placement time and includes a project-based component is recommended for future placements. Project-based and online elements provide genuine and valuable learning opportunities for physiotherapy students in preparation for real-world work.
Patterns of Egg Consumption Can Help Contribute to Nutrient Recommendations and Are Associated with Diet Quality and Shortfall Nutrient Intakes

Limited data are available on how eggs are consumed in the typical American eating pattern and the contribution to usual intakes, diet quality and in meeting recommendations. The objectives of the present analysis included identifying how eggs are consumed within U.S. dietary patterns and how these patterns are associated with the usual intakes of shortfall nutrients and diet quality (Healthy Eating Index 2015) using data from the combined National Health and Nutrition Examination Survey (NHANES) from 2001–2016. An additional objective included assessing the differences between egg consumers and egg non-consumers in nutrient intakes and nutrient adequacy. Several egg-containing dietary patterns were identified, and two egg patterns were associated with a greater diet quality compared to a no egg pattern (p < 0.0001). Most egg patterns identified were similar in diet quality scores when compared to the no egg pattern; however, the two egg patterns had lower diet quality scores. Egg consumption combined with a greater intake of total protein foods, seafood and plant protein, total vegetables, total fruit, whole fruit, whole grains and dairy foods, and a lower intake of refined grains and added sugars contributed to an improved diet quality, supporting that no one food is responsible for a healthy dietary pattern. Egg consumers demonstrated significantly higher intakes of dietary fiber, calcium, magnesium, potassium, total choline, vitamin A, vitamin C, vitamin D and vitamin E when compared to egg non-consumers. A comparison of egg consumers and egg non-consumers found egg consumers had significantly less percentages of the population below the EAR for calcium, iron, magnesium, vitamin A, vitamin C and vitamin E. Similarly, the percentage of the population above the recommendations for potassium and choline were greater for egg consumers vs. egg non-consumers. In egg consumers, 24.4% of the population was above the AI for dietary choline when compared to 4.3% of egg non-consumers (p < 0.0001). Findings from the present analysis demonstrate that eggs and egg-containing foods can be an important part of a healthy dietary pattern when balanced accordingly with other nutrient-dense foods.
Characterization and pollution potential of leachate from urban landfills during dry and wet periods in arid regions

Leachate originating from municipal solid waste landfills poses a serious contamination threat to public health. The study performed a bio-physicochemical characterization of leachate from two landfills in Oman, i.e., Multaqa landfill leachate (MLL) and Barka landfill leachate (BLL) before and after rainfall. Samples were characterized for ninety-two (92) parameters. Additionally, the leachate pollution index (LPI) was estimated to assess. The study found a high value of the leachate parameters without any rainfall incidents. Pearson correlations (±ve) have to be seen more than 90% in all cases, which is a strong association (r>0.75) for the measured parameters in both MLL and BLL. Rainfall significantly reduced the concentrations of organic contaminants and solids in leachate due to dilution. The study revealed about 18–29% and 14–28% reductions in the LPI sub-index for organic and inorganic contaminants, respectively, after the rainfall. The overall LPI values were higher compared to similar findings from the literature. Such deviations could be attributed to the unsegregated nature of solid wastes, resulting in the formation of contaminants or from the disposal of a high volume of solid wastes in a smaller area. Therefore, the study recommends efficient management strategies of landfills to reduce potential leachate groundwater contamination.
Numerical Analysis and Optimization of Flat Ends Parameters in Pressure Vessels with Rectangular Shape

Cylindrical pressure vessels with circular cross section are commonly used in the construction of various pressure apparatus; however in certain cases other cross sections are applied. The vessels with rectangular and elliptical perpendicular cross section are of the main interest and certain formulas for their calculations are stated in the respective codes [1, 2]. In these appliances flat ends of various shapes are usually used as the vessels caps. Similarly, as for the cylindrical boilers, flat end plates with stress relieve grooves are recommended. Like in the flat ends for cylindrical pipes certain variation of the groove parameters is possible but again no clear suggestion is given how to choose the optimal groove parameters providing the minimum stress concentration [3]. In this paper the numerical analysis and optimization of the admitted by code [1] groove parameters is presented for the pipe with the rectangular cross section subjected to the internal pressure.

Process conditions affecting the physical quality of alfalfa pellets

The physical quality of alfalfa pellets can be optimized by control of the manufacturing process. Process conditions studied were conditioning and pellet temperature, die geometry (length-to-diameter or l/d ratio), hammer mill screen size used in grinding the dehydrated hay chops, and die speed. As conditioning temperature increased, the durability of the pellets also increased. Pellet temperature increased with conditioning temperature. Pellet temperature has a significant effect on pellet durability. The l/d ratio also directly affects pellet durability. The die with a high l/d ratio produced more durable pellets. Differences due to the screen size of the hammer mill used in grinding the chops and the die speeds were not significant. A correlation between energy consumption and pellet durability was developed.
