Body-site distribution of skin cancer, pre-malignant and common benign pigmented lesions excised in general practice

Background Concern about skin cancer is a common reason for people from predominantly fair-skinned populations to present to primary care doctors. Objectives To examine the frequency and body-site distribution of malignant, pre-malignant and benign pigmented skin lesions excised in primary care. Methods This prospective study conducted in Queensland, Australia, included 154 primary care doctors. For all excised or biopsied lesions, doctors recorded the patient's age and sex, body site, level of patient pressure to excise, and the clinical diagnosis. Histological confirmation was obtained through pathology laboratories. Results Of 9650 skin lesions, 57·7% were excised in males and 75·0% excised in patients ≥50years. The most common diagnoses were basal cell carcinoma (BCC) (35·1%) and squamous cell carcinoma (SCC) (19·7%). Compared with the whole body, the highest densities for SCC, BCC and actinic keratoses were observed on chronically sun-exposed areas of the body including the face in males and females, the scalp and ears in males, and the hands in females. The density of BCC was also high on intermittently or rarely exposed body sites. Females, younger patients and patients with melanocytic naevi were significantly more likely to exert moderate/high levels of pressure on the doctor to excise. Conclusions More than half the excised lesions were skin cancer, which mostly occurred on the more chronically sun-exposed areas of the body. Information on the type and body-site distribution of skin lesions can aid in the diagnosis and planned management of skin cancer and other skin lesions commonly presented in primary care.

Computing in performing arts education and practice

The performing arts have traditionally made limited use of and showed limited acceptance of computing technology. There are cognitive, physical, environmental, and social influences on the use of computers in performing arts. This paper will examine those influences on the practice of computers in the performing arts and their implications for education in those areas. These implications for the learning environment include infrastructure, interface design, industrial design, and software functionality. Although many of the issues raised in this paper are common to all visual and performing arts, there are significant differences between them which require abstraction of the concepts presented in this paper beyond the more practical focus intended. In particular there are differences in the ways humans are involved in the presentation of a work, and the transitory verses static nature of time in art products.

Drawing together as inclusive practice in early years learning

Contemporary critiques on early years education highlight a call for the need to implement teaching and learning strategies that are less managing, that emerge from equity and inclusivity agendas, and that recognise diversity and plurality in early years learning contexts. Such critiques raise a need to reconsider the ways we engage as adults with children, and to rethink how we might review these relational subjectivities in respect to teaching and learning. This paper focuses on some aspects of a pilot research study into collaborative drawing in order to discuss ideas about socially inclusive early childhood pedagogies.

Black v Garnock : implications for Queensland conveyancing practice

What was previously established as a fundamental principle, that a judgment creditor may take no interest beyond what the judgment debtor could give, has now been called into question by the decision of the High Court in Black v Garnock [2007] HCA 31. This article examines the implications of the decision of the High Court for conveyancing practice in Queensland. The relevant facts of Black v Garnock [2007] HCA 31 may be briefly stated: The Garnocks and the Luffs, as purchasers, entered a contract to purchase a rural property from Mrs Smith with settlement due on 24 August 2005. On 23 August 2005, a creditor obtained a writ against Mrs Smith from the District Court of New South Wales. No caveat was lodged on behalf of the purchasers prior to settlement (there being no equivalent, in New South Wales, of the Queensland settlement notice mechanism).

Managing specialised knowledge in technopreneurial firms : the Australian experience

Technology-oriented young firms play an important role for innovation and commercialisation of new ideas. These firms are often founded by engineers, scientists or academics who posses great scientific/technological knowledge, but limited know-how in other aspects of managing a business including knowledge management. Successful managing and integrating their specialised knowledge is of particular importance when it comes to developing a new product or process. This article therefore focuses on the particularities of the knowledge management process in technopreneurial firms. Using a qualitative investigation from a sample of Australian SMEs, a number of key observations are derived which show the challenges of managing knowledge and how important knowledge management is as a management tool for R&D and innovation process in technology-oriented SMEs. Findings suggest that knowledge management and integration processes in these firms are very much project focused and mainly based on ad hoc and informal processes and not embedded within the overall organisational routines.

Defining and mapping teacher practice in technology classrooms

The indecision surrounding the definition of Technology extends to the classroom as not knowing what a subject “is” affects how it is taught. Similarly, its relative newness – and consequent lack of habitus in school settings - means that it is still struggling to find its own place in the curriculum as well as resolve its relationship with more established subject domains, particularly Science and Mathematics. The guidance from syllabus documents points to open-ended student-directed projects where extant studies indicate a more common experience of teacher –directed activities and an emphasis on product over process. There are issues too for researchers in documenting classroom observations and in analysing teacher practice in new learning environments. This paper presents a framework for defining and mapping classroom practice and for attempting to describe the social practice in the Technology classroom. The framework is a bricolage which draws on contemporary research. More formally, the development of the framework is consonant with the aim of design-based research to develop a flexible, adaptive and generalisable theory to better understanding a teaching domain where promise is not seen to match current reality. The framework may also inform emergent approaches to STEM (Science, Technology, Education and Mathematics) in education.

Maximum recovery after knee replacement - the MARKER study rationale and protocol

Background There is little scientific evidence to support the usual practice of providing outpatient rehabilitation to patients undergoing total knee replacement surgery (TKR) immediately after discharge from the orthopaedic ward. It is hypothesised that the lack of clinical benefit is due to the low exercise intensity tolerated at this time, with patients still recovering from the effects of major orthopaedic surgery. The aim of the proposed clinical trial is to investigate the clinical and cost effectiveness of a novel rehabilitation strategy, consisting of an initial home exercise programme followed, approximately six weeks later, by higher intensity outpatient exercise classes. Methods/Design In this multicentre randomised controlled trial, 600 patients undergoing primary TKR will be recruited at the orthopaedic pre-admission clinic of 10 large public and private hospitals in Australia. There will be no change to the medical or rehabilitative care usually provided while the participant is admitted to the orthopaedic ward. After TKR, but prior to discharge from the orthopaedic ward, participants will be randomised to either the novel rehabilitation strategy or usual rehabilitative care as provided by the hospital or recommended by the orthopaedic surgeon. Outcomes assessments will be conducted at baseline (pre-admission clinic) and at 6 weeks, 6 months and 12 months following randomisation. The primary outcomes will be self-reported knee pain and physical function. Secondary outcomes include quality of life and objective measures of physical performance. Health economic data (health sector and community service utilisation, loss of productivity) will be recorded prospectively by participants in a patient diary. This patient cohort will also be followed-up annually for five years for knee pain, physical function and the need or actual incidence of further joint replacement surgery. Discussion The results of this pragmatic clinical trial can be directly implemented into clinical practice. If beneficial, the novel rehabilitation strategy of utilising outpatient exercise classes during a later rehabilitation phase would provide a feasible and potentially cost-effective intervention to optimise the physical well-being of the large number of people undergoing TKR.

Developing ethical identities in young offenders through restorative justice practice in Australia

Restorative justice is firmly established in Australian juvenile justice. While the official language used to describe restorative initiatives varies across states and territories, the most common form is a meeting or conference between young offenders and their victims (most commonly known as a family group or youth justice conference). During the past decade, an impressive amount of empirical research has examined how the restorative justice process affects offenders, victims and other participants (such as supporters for young offenders and victims). Results from this line of research are remarkably consistent and show that participants generally regard restorative conferences as procedurally fair and that they are satisfied with the outcomes (eg what young offenders agree to do to make up for their offending behaviour, such as offer a sincere apology or perform work for the victim or the community). What is less common, however, is the perception among participants that restorative conferences achieve the key aim of restoration.By ‘restoration’ we refer to encounters where ‘offenders apologise, their apologies are accepted, victims offer forgiveness,and conferences conclude with a feeling of mutual good will’.

A survey of the use of grading scales for contact lens complications in optometric practice

Purpose:  The aim of this study was to investigate the extent and pattern of use of grading scales for contact lens complications (‘grading scales’) in optometric practice. Methods:  An anonymous postal survey was sent to all 756 members of the Queensland Division of Optometrists Association Australia. Information was elicited relating to level of experience, practice type and location, and mode of usage of grading scales. Results:  Survey forms were returned by 237 optometrists, representing a 31 per cent response rate. The majority of respondents (61 per cent) reported using grading scales frequently in practice, while 65 per cent of these preferred to use the Efron Grading Scales for Contact Lens Complications. Seventy-six per cent of optometrists use a method of incremental grading rather than simply grading with whole numbers. Grading scales are more likely to be used by optometrists who have recently graduated (p < 0.001), have a postgraduate certificate in ocular therapeutics (p = 0.018), see more contact lens patients (p = 0.027) and use other forms of grading scales (p < 0.001). The most frequently graded ocular conditions were corneal staining, papillary conjunctivitis and conjunctival redness. The main reasons for not using grading scales included a preference for sketches, photographs or descriptions (87 per cent) and unavailability of scales (29 per cent). Conclusion:  Grading scales for contact lens complications are used extensively in optometric practice for a variety of purposes. This tool can now be considered as an expected norm in contact lens practice. We advocate the incorporation of such grading scales into professional guidelines and standards for good optometric clinical practice.
