Re-engaging learners in schooling through applied learning reform : exploring the Victorian Certificate of Applied Learning as an 'alternative' senior schooling pathway in Australia

The Victorian Certificate of Applied Learning (VCAL) emerged in Australia to provide more relevant curriculum programs that would cater for increasing retention rates of high school students. It is also an example of the ‘new’ learning arising from contemporary debates and reforms that highlight inadequacies of the more traditional modes of learning. This book focuses on the pedagogical and sociological issues emerging from the VCAL being introduced as an ‘alternative’ learning pathway for ‘at-risk’ students within a traditional high school culture. Through the eyes of an insider- researcher, the book argues for a deeper understanding of applied learning as a ‘re-engaging’ pedagogy by studying the schooling experience of VCAL students and teachers. The book concludes that traditional modes of school teaching contribute to the social construction of ‘at-risk’ students and argues that high school pedagogy needs to be redefined as a cultural phenomenon requiring teachers to be reflexively aware of their role in bridging the gap between students’ life experiences and the curriculum.

Investigation of proton dynamics and the proton transport pathway in choline dihydrogen phosphate using solid-state NMR

Choline dihydrogen phosphate has previously been shown to be a good ionic conductor as well as an excellent host for acid doping, leading to high proton conductivities required for e.g., electrochemical devices including proton membrane fuel cells and sensors. A combination of variable-temperature ¹H solid-state NMR and 2D NMR pulse sequences, including ³¹P and ¹³C CODEX and ¹H BaBa, show that the proton conduction mechanism primarily involves assisted transport via a restricted three-site motion of the phosphate unit around the P–O bond that is hydrogen bonded to the choline and exchange of protons between these anions. In other words, proton transport at ambient temperatures appears to occur most favorably along the crystallographic b axis, from phosphate dimer to dimer. At elevated temperatures exchange between the protons of the hydroxyl group on the choline cation and the hydrogen-bonded dihydrogen phosphate groups also contributes to the structural diffusion of the protons in this solid state conductor.

An evaluation of a mental health screening and referral pathway for community nursing care : nurses' and general practitioners' perspectives

Aims and objectives. To evaluate a feasible, best practice mental health screening and referral clinical pathway for generalist community nursing care of war veterans and war widow(er)s in Australia.
Background. War veterans commonly experience mental health difficulties and do not always receive required treatment, as can also occur for war widow(er)s. Whenever opportunity arises, such as during community nursing care, it is vital to identify mental health problems in a health promotion framework.
Design. A clinical pathway was developed by literature review and consultation and then trialled and evaluated using mixed methods – quantitative and qualitative.
Methods. Community nurses who trialled the pathway completed an evaluation survey and attended focus groups. General practitioners responded to an evaluation survey.
Results. Most nurses found the pathway clear and easy to understand but not always easy to use. They emphasised the need to establish trust and rapport with clients prior to implementing the pathway. It was sometimes difficult to ensure effective referral to general practitioners for clients who screened positive for a mental health problem. When referral was accomplished, general practitioners reported adequate and useful information was provided. Some general practitioners also commented on the difficulty of achieving effective communication between general practitioners and nurses.
Conclusions. Nurses and some general practitioners found the pathway useful for their practice. They offered several suggestions for improvement by simplifying the trialled pathway and accompanying guidelines and strategies to improve communication between nurses and general practitioners. This study adds understanding of how community nurses might productively screen for mental health difficulties.
Relevance to clinical practice. The trialled pathway, which was modified and refined following the study, is an evidence-based
resource for community nurses in Australia and similar contexts to guide practise and maximise holistic care for war veterans and war widow(er)s and possibly other client groups.

A pathway to enhancing professionalism: building a bridge between TAFE and university early childhood qualifications

It has been argued that a key strategy to improve developmental and educational outcomes for young children is to increase the number of childcare staff with early childhood university degrees (Saracho & Spodek, 2007). In order to upgrade the qualifications of staff, a number of Australian universities provide pathways that enable graduates of early childhood diploma programs to complete a degree. Several impediments, including institutional structures and individual contextual and personal factors, may affect these pathways. Although a range of organisations offer diploma programs, TAFE (Tertiary and Further Education) is a major provider. The aim of the present study was to investigate student transition between early childhood programs in TAFE and university. The research drew on several data sources, including a survey of the perceptions of students at various points of undertaking the transition. The current credit arrangement for TAFE Diploma graduates was found to be satisfactory; however, gaps were identified between the TAFE and university teaching and learning arrangements with regard to curriculum structures, teaching styles and assessment. Graduates of both programs considered that the completion of both awards would have a positive effect on their careers.

A reverse pathway? Actual and perceived skill proficiency and physical activity

Purpose: Motor skills are considered a prerequisite to physical activity, yet the relationship may be reciprocal and perceived sports competence might mediate associations.
Methods: In 2006/2007, 215 adolescents completed motor skill proficiency (Get Skilled Get Active), perceived sport competence (Physical Self-Perception Profile) and physical activity assessments (Adolescent Physical Activity Recall Questionnaire) as part of the Physical Activity and Skills Study. Using AMOS (Version 7.0), reciprocal relationships were examined between motor skill (object control and locomotor) and moderate to vigorous physical activity (MVPA). Both models were then run in different versions to understand the role of perceived sports competence as a potential mediator.
Results: Mean age was 16.4 yr (SD = 0.6), 51.6% (111/215) were females. A reciprocal relationship between object control and MVPA and a one-way relationship from MVPA to locomotor skill was found. When perceived sports competence was examined as a mediator, the best-fitting model versions explained 16% (R² = 0.16)
MVPA variation, and 30% object control (R² = 0.30), and 12% locomotor skill variation (R² = 0.12) (reverse relationship). Perceived sports competence partially mediates the relationship between object control proficiency and physical activity for both directions and fully mediates the relationship between physical activity and locomotor skill; but only when locomotor skill is the outcome.
Conclusions: If the relationship between object control skill and physical activity is viewed as a ‘‘positive feedback loop,’’ skill development and increasing physical activity should simultaneously be targeted in physical activity interventions. Increasing perceived sport competence should also be an intervention focus.

Role of Jak2/Stat5/Cis pathway components in zebrafish development

By utilizing the zebrafish as a research model, the function of specific cell signalling pathway components in development was investigated. This revealed new roles for the so-called Jak2/Stat5/Cis pathway in blood and sensory organ development, and a conserved prolactin pathway despite divergent functions between species.

Mixed methods evaluation research for a mental health screening and referral clinical pathway

Rationale: This study is an exemplar of mixed method evaluation research for development of a clinical pathway.

Aim: To develop and evaluate an evidence-based, feasible mental health screening and referral clinical pathway for Department of Veterans’ Affairs-funded community nursing care of war veterans and war widows in the Australian context.

Methods: Mixed methods were applied to formulate and clinically evaluate an appropriate pathway. The pathway was applied at urban and rural sites for the nursing care of 97 war veteran and war widow clients. Evaluative data were collected from clients, their informal carers, community nurses, and general practitioners. Chart auditing and pre-post measures were undertaken. Collaboration occurred with an interdisciplinary design team.

Results: The final modified six-page pathway includes use of validated screening tools (Kessler Psychological Distress Scale [K10]) and Alcohol Use Disorder Identification Test, appropriate referral information, directions for support and health-promoting education, and evidence-based guidelines. Implications for Practice: The clinical pathway is a useful, tested, evidence-based guide for generalist community nurses to identify and suitably respond to common mental healthcare needs of war veterans and war widows. The pathway provides outcomes acceptable to clients and their carers, nurses and doctors.

Conclusions: This study provides an evaluated clinical pathway for generalist community nurses to screen for mental health difficulties, make appropriate referrals as required and to support war veteran and war widow clients. However, the study also shows how research can be used to develop and evaluate
practical, evidence-based clinical pathways.

Transcriptional regulation of the yghJ-pppA-yghG-gspCDEFGHIJKLM cluster, encoding the type II secretion pathway in Enterotoxigenic Escherichia coli

The gene cluster gspCDEFGHIJKLM codes for various structural components of the type II secretion pathway which is responsible for the secretion of heat-labile enterotoxin by enterotoxigenic Escherichia coli (ETEC). In this work, we used a variety of molecular approaches to elucidate the transcriptional organization of the ETEC type II secretion system and to unravel the mechanisms by which the expression of these genes is controlled. We showed that the gspCDEFGHIJKLM cluster and three other upstream genes, yghJ, pppA, and yghG, are cotranscribed and that a promoter located in the upstream region of yghJ plays a major role in the expression of this 14-gene transcriptional unit. Transcription of the yghJ promoter was repressed 168-fold upon a temperature downshift from 37°C to 22°C. This temperature-induced repression was mediated by the global regulatory proteins H-NS and StpA. Deletion mutagenesis showed that the promoter region encompassing positions −321 to +301 relative to the start site of transcription of yghJ was required for full repression. The yghJ promoter region is predicted to be highly curved and bound H-NS or StpA directly. The binding of H-NS or StpA blocked transcription initiation by inhibiting promoter open complex formation. Unraveling the mechanisms of regulation of type II secretion by ETEC enhances our understanding of the pathogenesis of ETEC and other pathogenic varieties of E. coli.
