Abstract: This paper aims to analyse, through the lens of learning network theory, ways in which external VET practitioners work within private enterprises to promote learning within these organizations. The paper is based on analyses of six case studies in two Australian States, each comprising a vocational education institute and an enterprise. In total, 34 interviews were held with four groups of participant – TAFE managers and practitioners, enterprise personnel and worker‐learners – from different industries. The paper finds that the overlaying of an external learning system on existing learning systems brings inevitable tensions that need to be carefully managed. VET practitioners working in industry operate in two worlds with very different cultures. They need to learn how to work within different power structures, how to build around existing work and learning networks, and how to mesh in with the flow of enterprise work. In the process of working with company staff, and crossing boundaries, they may well be creating a “third space” in which new meanings can be, and have to be, constructed that go beyond the limits of either site. The paper shows that understanding these ways of working has practical implications for VET managers and practitioners, company staff and policy‐makers in terms of how human resources are managed and how different parties work together. The paper shows two objectives: a relatively new focus in the research literature and an extension of learning network theory in terms of external learning systems.

Abstract: ABSTRACT The Iron Quadrangle (IQ) region in Minas Gerais is remarkably geobio erse, despite a long history of anthropogenic pressures such as mining and urbanization, but still lacks detailed studies on the distribution of its remaining native vegetation in different substrates. In this study, we utilized Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images, besides Gamma-spectrometry (Gamma) survey data associated with existing geological mapping (GM) and extensive fieldwork, to discriminate and quantify remnants of vegetation on ferruginous substrates in the IQ. The Maximum Likelihood (ML) algorithm was used to classify the vegetation types, thus named: open Rupestrian Field, shrubby Rupestrian Field, Capão Forest, Cerrado stricto sensu, Cerrado Field, Seasonal Forests, Pastures and Reforestation (the latter three regardless of substrate type) associated with the predominant substrates (ferruginous ironstone, phyllites, and quartzite). The use of ASTER images alone did not allow a reliable separation of ferruginous and non-ferruginous substrates, but the integration of all different data (ASTER-ML + Gamma + GM) allowed the provisional mapping of the vegetation associated with ferruginous substrates, potentially ferruginous and non-ferruginous substrates. The resulting map shows that the vegetation on ferruginous and potentially ferruginous substrates cover 8.7% and 6.9% of the IQ, respectively. The detailed analysis of the distribution and fragmentation of phytophysiognomies on ferruginous substrates is of great importance for developing strategies to conserve the geobio ersity of the IQ, and need to be further refined by checking and field mapping by novel approaches.

Abstract: In the 1990s, one of Australia's police services moved from a centralised, academy‐based system of training towards a more integrated model of professional development. As a consequence, probationary constables spent reduced time in the police academy (6 months) before moving into the workplace for 18 months of work‐based learning. This paper explores how those changes affected the ways in which probationary constables are viewed and accepted into the workforce. A useful model for this exploration is that of legitimate peripheral participation, as advocated by Lave and Wenger in 1991. Although Lave and Wenger acknowledge that peripherality, rather than being a negative term, allows for an understanding of inclusion into a community of practice, there is still a long journey to be travelled before full acceptance is accorded to the newcomer. By exploring the “voices” of the probationers and their senior officers, the conflicts and difficulties that arose during their work‐based probation and the negotiations required to help develop competent police officers, it is possible to trace the journey of probationary constables from periphery to a more central acceptance. This paper explores how the probationary constables were viewed and accepted into the workforce to become full and trusted members of a community of practice.

Abstract: Proposes to provide a description of the factors that underlie retention and to develop a model of the process of retention. A qualitative study was conducted in a selected number of occupational areas. Interviews were conducted with apprentices and trainees employed under a contract of training apprentices/trainees who had recently completed their contract of training employers/workplace supervisors and teachers/trainers. Provides information about a range of factors and how they combined to shape the process of retention. Recognises that some of the identified factors are more amenable to interventions to enhance retention than others. The study did not attempt to cover all occupations in which apprentices are employed, or to provide any ranking of importance of factors in relation to the retention process. The study encourages a holistic understanding of the process of retention and emphasises the dynamic nature of this process over the period of a contract of training. A useful source of information for those concerned with designing interventions that target factors that are most amenable to promoting enhanced retention in apprenticeships. This paper addresses the often neglected process of retention and offers some guidance in the design of interventions to promote retention in apprenticeships.

Abstract: This paper aims to explore why harmonisation, given its potential, is so difficult to achieve. It analyses the issues and challenges in achieving harmonisation of training and development across an industry. The approach was a meta-analysis of six research projects undertaken in the Australian rail industry. These projects varied in duration from 12-24 months. Between 2009 and 2013, rail employees in varying roles and levels of seniority, including middle managers, front-line supervisors, rail incident investigators, track workers and drivers, were interviewed ( n = 176) and surveyed ( n = 341). The meta-analysis identified a range of characteristics associated with harmonisation. It uncovered three categories of harmonisation, seven types of risk modelled in a layered risk pyramid and analysed key structural, environmental and organisational barriers to harmonisation. The paper concludes that harmonisation struggles to gain strategic significance and is h ered by operational pragmatism. There are few published papers examining harmonisation across companies or based on meta-analyses, especially qualitatively. Despite limitations of insufficient detail to allow close analysis, potentially variable quality data across projects from which to develop a meta-analysis and the danger of comparing apples with oranges, more attempts using this approach would be helpful in gaining nuanced insights into an industry. Achieving industry harmonisation requires significant change in the mindset of executives. To enhance the chances of harmonisation, there is need for a strong national entity with overview of the entire industry, high-quality training and development resources and activities and cost-benefit analyses and active c aigns. A major outcome of this research is the risk pyramid, which can be used by managers as a strategic evaluation tool. By using such tools based on sound research, leaders can be equipped to make informed decisions and reduce downstream risks. This research has value in extending the literature in two main ways: through examining the notion of harmonisation across an industry as distinct from within organisations that has been the focus of most studies and through using qualitative meta-analysis in a field dominated by quantitative approaches. It analyses the grey areas between rhetoric about its potential and difficulties in its achievement.

Abstract: Evidence indicates that increases in sympathetic nervous activity (SNA), and acclimatization to high altitude (HA), may reduce endothelial function as assessed by brachial artery flow-mediated dilatation (FMD) however, it is unclear whether such changes in FMD are due to direct vascular constraint, or consequential altered hemodynamics (e.g., shear stress) associated with increased SNA as a consequence of exposure to HA. We hypothesized that 1) at rest, SNA would be elevated and FMD would be reduced at HA compared with sea-level (SL) and 2) at SL and HA, FMD would be reduced when SNA was acutely increased, and elevated when SNA was acutely decreased. Using a novel, randomized experimental design, brachial artery FMD was assessed at SL (344 m) and HA (5,050 m) in 14 participants during mild lower-body negative pressure (LBNP −10 mmHg) and lower-body positive pressure (LBPP +10 mmHg). Blood pressure (finger photoplethysmography), heart rate (electrocardiogram), oxygen saturation (pulse oximetry), and brachial artery blood flow and shear rate (Duplex ultrasound) were recorded during LBNP, control, and LBPP trials. Muscle SNA was recorded (via microneurography) in a subset of participants ( n = 5). Our findings were 1) at rest, SNA was elevated ( P 0.01), and absolute FMD was reduced ( P = 0.024), but relative FMD remained unaltered ( P = 0.061), at HA compared with SL and 2) despite significantly altering SNA with LBNP (+60.3 ± 25.5%) and LBPP (−37.2 ± 12.7%) ( P 0.01), FMD was unaltered at SL ( P = 0.448) and HA ( P = 0.537). These data indicate that acute and mild changes in SNA do not directly influence brachial artery FMD at SL or HA. NEW & NOTEWORTHY The role of the sympathetic nervous system on endothelial function remains unclear. We used lower-body negative and positive pressure to manipulate sympathetic nervous activity at sea level and high altitude and measured brachial endothelial function via flow-mediated dilation. We found that acutely altering sympathetic nervous activity had no effect on endothelial function.
