Development of a new ultrasound-based system for tracking motion of the human lumbar spine: Reliability, stability and repeatability during forward bending movement trials

The aim of this study was to develop a new method for quantifying intersegmental motion of the spine in an instrumented motion segment L4–L5 model using ultrasound image post-processing combined with an electromagnetic device. A prospective test–retest design was employed, combined with an evaluation of stability and within- and between-day intra-tester reliability during forward bending by 15 healthy male patients. The accuracy of the measurement system using the model was calculated to be ± 0.9° (standard deviation = 0.43) over a 40° range and ± 0.4 cm (standard deviation = 0.28) over 1.5 cm. The mean composite range of forward bending was 15.5 ± 2.04° during a single trial (standard error of the mean = 0.54, coefficient of variation = 4.18). Reliability (intra-class correlation coefficient = 2.1) was found to be excellent for both within-day measures (0.995–0.999) and between-day measures (0.996–0.999). Further work is necessary to explore the use of this approach in the evaluation of biomechanics, clinical assessments and interventions.

'Create a better online you': Designing online learning resources to develop undergraduate social media skills

‘Create a Better Online You’ (CBOY) is an emerging initiative from QUT Library. CBOY focusses on developing the social media skills of undergraduates at QUT. While many students will have encountered ‘cybersafety’ training in primary or secondary school, a comprehensive environmental scan revealed little in the way of social media resources targeted at undergraduates. In particular, there was little to no focus on the ways in which social media could be used strategically to develop a positive online reputation and enhance chances of employability post tertiary education. The resources created as part of CBOY are the result of a literature review, environmental scan, and discussions with staff and students at QUT. Following the comprehensive environmental scan, it appears that CBOY represents one of the first free, openly accessible, interactive resources targeting the social media skills of undergraduates.

The Black Label: trade mark dilution, culture jamming, and the no logo movement

This article considers the ongoing debate over the appropriation of well-known and famous trade marks by the No Logo Movement for the purposes of political and social critique. It focuses upon one sensational piece of litigation in South Africa, Laugh It Off Promotions v. South African Breweries International (Finance) B.V. t/a Sabmark International. In this case, a group called Laugh It Off Promotions subjected the trade marks of the manufacturers of Carling Beer were subjected to parody, social satire, and culture jamming. The beer slogan “Black Label” was turned into a T-Shirt entitled “Black Labour/ White Guilt”. In the ensuing litigation, the High Court of South Africa and the Supreme Court of Appeal were of the opinion that the appropriation of the mark was a case of hate speech. However, the Constitutional Court of South Africa disagreed, finding that the parodies of a well-known, famous trade mark did not constitute trade mark dilution. Moseneke J observed that there was a lack of evidence of economic or material harm; and Sachs J held that there is a need to provide latitude for parody, laughter, and freedom of expression. The decision of the Constitutional Court of South Africa provides some important insights into the nature of trade mark dilution, the role of parody and satire, and the relevance of constitutional protections of freedom of speech and freedom of expression. Arguably, the ruling will be of help in the reformation of trade mark dilution law in other jurisdictions – such as the United States. The decision in Laugh It Off Promotions v. South African Breweries International demonstrates that trade mark law should not be immune from careful constitutional scrutiny.

Comparison of baseline information literacy skills of undergraduate and graduate Nurses at the University of Queensland: a pilot study by health librarians

Pilot studies are conducted to explain the baseline information literacy skills prevailing in the undergraduate and graduate nurses at the University of Queensland. The analyses reveal a significant difference between the skills of both the nurses, hence demonstrating the need for the development of new information literacy workshops. The author also presents various teaching strategies that can be adopted for an effective skill development of these nurses.

Also fully updated and revised to reflect the changes in 2014 is the Tax Rates and Tables section, which contains an accessible summary of the main tax rates and tables that students will need to refer to for their tax studies.

An enquiry into the professional competence of inclusive education teachers in Beijing: Attitudes, knowledge, skills, and agency

Attitudes, knowledge, and skills are widely recognised as the three pillars of professional competence of inclusive education teachers. Studies emerging from the Chinese context consider these three pillars important for the practice of Learning in Regular Classrooms—an idiosyncratic Chinese form of inclusive education. Our mixed methods study reveals that agency is the fourth pillar of the professional competence for inclusive education teachers in Beijing, China. Results from comparative analysis indicate that the level of teachers’ agency is significantly lower than that of their attitudes, knowledge, and skills. We offer some implications for policy and practice in inclusive education.

Teaching independent learning skills in the first year: A positive psychology strategy for promoting law student well-being

Empirical evidence in Australia and overseas has established that in many university disciplines, students begin to experience elevated levels of psychological distress in their first year of study. There is now a considerable body of empirical data that establishes that this is a significant problem for law students. Psychological distress may hamper a law student’s capacity to learn successfully, and certainly hinders their ability to thrive in the tertiary environment. We know from Self-Determination Theory (SDT), a conceptual branch of positive psychology, that supporting students’ autonomy in turn supports their well-being. This article seeks to connect the literature on law student well-being and independent learning using Self-Determination Theory (SDT) as the theoretical bridge. We argue that deliberate instruction in the development of independent learning skills in the first year curriculum is autonomy supportive. It can therefore lay the foundation for academic and personal success at university, and may be a protective factor against decline in law student psychological well-being.

Exploring an innovative educational approach to facilitating student nurses' clinical-reasoning skills in North Sulawesi Province, Indonesia

This study examined the effect of an educational intervention utilizing principles of cognitive apprenticeship on students’ ability to apply clinical reasoning skills within the context of a purpose-built clinical vignette. A quasi-experimental, non-equivalent control-group design was used to evaluate the effect of the educational intervention on students’ accuracy, inaccuracy and self-confidence in clinical reasoning. This study makes an important contribution to nursing education by providing evidence to understand how best to facilitate nursing students’ development of clinical reasoning.

Peer mentoring for radiotherapy planning skills development: A pilot study

Introduction: This study aimed to determine the potential role and guidelines for implementation of skill-based peer mentoring for radiotherapy planning education. Methods: After four weekly mentoring sessions, both Year 3 mentors (n=9) and Year 2 mentees (n=9) were invited to complete a short online questionnaire relating to the impact of the initiative. The tool contained a mixture of Likert-style questions concerning student enjoyment and perceived usefulness of the initiative as well as more qualitative open questions that gathered perceptions of the peer mentoring process, implementation methods and potential future scope. Results: Several key discussion themes related to benefits to each stakeholder group, challenges arising, improvements and potential future directions. There were high levels of enjoyment and perceived value of the mentoring from both sides with 100% of the 18 respondents enjoying the experience. The informal format encouraged further learning, while mentors reported acquisition of valuable skills and gains in knowledge. Conclusions: Peer mentoring has a valuable and enjoyable role to play in radiotherapy planning training and helps consolidate theoretical understanding for experienced students. An informal approach allows for students to adopt the most appropriate mentoring model for their needs while providing them with a free space to engender additional discussion.

Early mathematical learning: Number processing skills and executive function at 5 and 8 years of age

This research investigated differences and associations in performance in number processing and executive function for children attending primary school in a large Australian metropolitan city. In a cross-sectional study, performance of 25 children in the first full-time year of school, (Prep; mean age = 5.5 years) and 21 children in Year 3 (mean age = 8.5 years) completed three number processing tasks and three executive function tasks. Year 3 children consistently outperformed the Prep year children on measures of accuracy and reaction time, on the tasks of number comparison, calculation, shifting, and inhibition but not on number line estimation. The components of executive function (shifting, inhibition, and working memory) showed different patterns of correlation to performance on number processing tasks across the early years of school. Findings could be used to enhance teachers’ understanding about the role of the cognitive processes employed by children in numeracy learning, and so inform teachers’ classroom practices.

A new protest movement: Flexn your message through dance

Flexing, or Flex, is a street dance style that originated in Jamaica in the 1990s and grew up on the streets of Brooklyn, East New York. Performed to dancehall and reggae music, it has since evolved into a protest movement - an avenue for “flexors” to rally against social injustice, police brutality and racism.

Using collaboration and technology to enhance Vietnamese students' English language writing skills

This action research study investigated face-to-face and wiki technology collaboration to enhance students' English writing skills in a second language (L2) class in Vietnam. The thesis is underpinned by socio-cultural theory and argues that collaborative learning using wikis led to an enhancement in L2 writing skills. The findings show that collaborating via wikis challenged traditional L2 writing pedagogy in the following ways: increased student autonomy; understanding formative feedback; and awareness of process writing, genre and audiences. This study contributes practical knowledge about affordances and constraints of collaborative writing using wikis in Vietnam and other countries where traditional pedagogies are prevalent.

The influence of Lord Robert Baden-Powell on the development of the Boy Scout Movement with observations on its operation in Queensland 1907-1937

The purpose of the Boy Scout Movement was to create boys who were honest, obedient to constituted authority and loyal to the King and the British Empire. This thesis examines the influence that Scouting's founder, Lord Robert Baden-Powell, had on the development of Scouting in Queensland in the period 1907 to 1937, and concludes that that influence was profound. Baden-Powell conceived the Boy Scout Movement, and its non-formal educative method as an answer to some of the social, economic, and political problems at the beginning of the twentieth century – a paradigm recognised and acknowledged by educators of the day.

Experimental studies on the performance of rail joints with modified wheel/railhead contact

Rail joints are provided with a gap to account for thermal movement and to maintain electrical insulation for the control of signals and/or broken rail detection circuits. The gap in the rail joint is regarded as a source of significant problems for the rail industry since it leads to a very short rail service life compared with other track components due to the various, and difficult to predict, failure modes – thus increasing the risk for train operations. Many attempts to improve the life of rail joints have led to a large number of patents around the world; notable attempts include strengthening through larger-sized joint bars, an increased number of bolts and the use of high yield materials. Unfortunately, no design to date has shown the ability to prolong the life of the rail joints to values close to those for continuously welded rail (CWR). This paper reports the results of a fundamental study that has revealed that the wheel contact at the free edge of the railhead is a major problem since it generates a singularity in the contact pressure and railhead stresses. A design was therefore developed using an optimisation framework that prevents wheel contact at the railhead edge. Finite element modelling of the design has shown that the contact pressure and railhead stress singularities are eliminated, thus increasing the potential to work as effectively as a CWR that does not have a geometric gap. An experimental validation of the finite element results is presented through an innovative non-contact measurement of strains. Some practical issues related to grinding rails to the optimal design are also discussed.
