The blind men and the elephant : music education in a changing world

Education provides unique opportunities for individuals to develop their full character as Australian citizens who can play a part in the shaping of the future. All educational settings have an important role to play in bridging differences and promoting mutual respect, tolerance and understanding between people of different races, cultures, and religions. The curriculum is one component of the wider educational milieu that should be 'an enabling mechanism that nurtures adjustment to change, and simultaneously provides a roadmap of expectation' (Bruniges, 2005, p.15). As the rate and diversity of both local and global change accelerates, education continues to be faced with a multiplicity of challenges. The ways in which we respond to this will influence both the society and the curriculum that we design, implement and evaluate. Currently music educators implementing the Victorian Essential Learning Standards (VELS) are faced with the challenge of developing multicultural practices that align with both curriculum initiatives and create authentic experiences for students. As in the well-known story of the blind men and the elephant, teachers are faced with resources that offer only a shallow introduction to what is a multifaceted field. The question we pose is: 'How do educators embrace a vast range of cultural and social dimensions in our school music programmes without being like a blind man, grasping only one perspective of an extensive and complex whole?'

Managing the donation service experience : a case study

This article examines the implications for nonprofits of managing donation exchanges using customer relationship management and service blueprinting. It presents a case study of one U.K.-based nonprofit and identifies a range of issues that might make managing donation service exchanges more complex than occurs in the for-profit setting. In particular, the fact that there are multiple simultaneous exchanges means that it may be difficult to separate donation processes from other organizational activities such as membership and campaigning. We explore the utility of service blueprinting in aiding the management of this complexity.

Review of the quality of studies on the economic effects of smoke-free policies on the hospitality industry

Objective: To compare the quality and funding source of studies concluding a negative economic impact of smoke-free policies in the hospitality industry to studies concluding no such negative impact.

Data sources: Researchers sought all studies produced before 31 August 2002. Articles published in scientific journals were located with Medline, Science Citation Index, Social Sciences Citation Index, Current Contents, PsychInfo, Econlit, and Healthstar. Unpublished studies were located from tobacco company websites and through internet searches.

Study selection: 97 studies that made statements about economic impact were included. 93% of the studies located met the selection criteria as determined by consensus between multiple reviewers.

Data extraction: Findings and characteristics of studies (apart from funding source) were classified independently by two researchers. A third assessor blind to both the objective of the present study and to funding source also classified each study.

Data synthesis: In studies concluding a negative impact, the odds of using a subjective outcome measure was 4.0 times (95% confidence interval (CI) 1.4 to 9.6; p = 0.007) and the odds of not being peer reviewed was 20 times (95% CI 2.6 to 166.7; p = 0.004) that of studies concluding no such negative impact. All of the studies concluding a negative impact were supported by the tobacco industry. 94% of the tobacco industry supported studies concluded a negative economic impact compared to none of the non-industry supported studies.

Conclusion: All of the best designed studies report no impact or a positive impact of smoke-free restaurant and bar laws on sales or employment. Policymakers can act to protect workers and patrons from the toxins in secondhand smoke confident in rejecting industry claims that there will be an adverse economic impact.

Constructing girlhood through the periodical press, 1850-1915

Focusing on six popular British girls' periodicals, Kristine Moruzi explores the debate about the shifting nature of Victorian girlhood between 1850 and 1915. During an era of significant political, social, and economic change, girls' periodicals demonstrate the difficulties of fashioning a coherent, consistent model of girlhood. The mixed-genre format of these magazines, Moruzi suggests, allowed inconsistencies and tensions between competing feminine ideals to exist within the same publication. Adopting a case study approach, Moruzi shows that the Monthly Packet, the Girl of the Period Miscellany, the Girl's Own Paper, Atalanta, the Young Woman, and the Girl's Realm each attempted to define and refine a unique type of girl, particularly the religious girl, the 'Girl of the Period,' the healthy girl, the educated girl, the marrying girl, and the modern girl. These periodicals reflected the challenges of embracing the changing conditions of girls' lives while also attempting to maintain traditional feminine ideals of purity and morality. By analyzing the competing discourses within girls' periodicals, Moruzi's book demonstrates how they were able to frame feminine behaviour in ways that both reinforced and redefined the changing role of girls in nineteenth-century society while also allowing girl readers the opportunity to respond to these definitions.

The integrative management of treatment-resistant depression: a comprehensive review and perspectives.

Major depressive disorder is a prevalent and disabling illness. Notwithstanding numerous advances in the pharmacological treatment of depression, approximately 70% of patients do not remit after first-line antidepressant treatment.

Blind estimation of MIMO relay channels

In this paper, we integrate two blind source separation (BSS) methods to estimate the individual channel state information (CSI) for the source-relay and relay-destination links of three-node two-hop multiple-input multiple-output (MIMO) relay systems. In particular, we propose a first-order Z-domain precoding technique for the blind estimation of the relay-destination channel matrix, while an algorithm based on the constant modulus and mutual information properties is developed to estimate the source-relay channel matrix. Compared with training-based MIMO relay channel estimation approaches, our algorithm has a better bandwidth efficiency as no bandwidth is wasted for sending the training sequences. Numerical examples are shown to demonstrate the performance of the proposed algorithm. © 2014 IEEE.

Blind channel estimation and signal retrieving for MIMO relay systems

In this paper, we propose a blind channel estimation and signal retrieving algorithm for two-hop multiple-input multiple-output (MIMO) relay systems. This new algorithm integrates two blind source separation (BSS) methods to estimate the individual channel state information (CSI) of the source-relay and relay-destination links. In particular, a first-order Z-domain precoding technique is developed for the blind estimation of the relay-destination channel matrix, where the signals received at the relay node are pre-processed by a set of precoders before being transmitted to the destination node. With the estimated signals at the relay node, we propose an algorithm based on the constant modulus and signal mutual information properties to estimate the source-relay channel matrix. Compared with training-based MIMO relay channel estimation approaches, the proposed algorithm has a better bandwidth efficiency as no bandwidth is wasted for sending the training sequences. Numerical examples are shown to demonstrate the performance of the proposed algorithm.

Look down, look up : Barbara Bolt's art beyond representation

I review the thinking of Barbara Bolt in her recent book, which is informed by Martin Heidegger’s theory of art. Bolt argues that it is in the flux of art practice, where the artist responds bodily, with hands and eyes, to the encounter with the materials of practice, that visual art produces real material effects. That is, through the praxical encounter, art does not merely represent, it performs radically. Bolt thus argues for a materialist ontology of the work of visual art. I examine what Bolt means by ‘real material effects’ and ‘radical performativity’.

In developing my own project on the poetic response to visual art, particularly portraiture, I have freely adapted Heidegger’s theory of art to propose that the poet responds to the visual encounter in a manner similar to that of Heidegger’s preserver, by restraining usual knowing and looking. In this way the poet facilitates the emergence from the work of visual art of truth about being and earth, as defined by Heidegger. In my forthcoming article ‘Ekphrasis and illumination of painting’, I argue that the poet, like the artist, restrains seeing-as and operates in a mode approximating mere seeing, as these terms are defined by Heidegger and Wittgenstein.

In the present article I propose to examine the role of looking down and looking up in non-representational art, and in particular Bolt’s ‘oil stain paintings’ exhibited in the Forty-five Downstairs gallery in Melbourne in conjunction with the launch of her book.

I propose to expose some blind spots in the thinking which underpins theories derived from Heidegger. I will examine the way ‘representation’ has been constructed in twentieth-century thought, and will argue that Heideggerian truth and Bolt’s ‘real material effects’ result from the privileging of perception over knowledge. I will examine, with particular reference to portraiture, Bolt’s assertion that the referent can be rehabilitated in Western thought and traced in ‘real material effects’. I will argue that ‘representation’ is an unstable process occurring within and outside signification, and that this very instability enables us to confidently predict that all art produces ‘real material effects’, or in other words, Heideggerian truth.

Design-related bias in hospital fall risk screening tool predictive accuracy evaluations: systematic review and meta-analysis.

Introduction: Fall risk screening tools are frequently used as a part of falls prevention programs in hospitals. Design-related bias in evaluations of tool predictive accuracy could lead to overoptimistic results, which would then contribute to program failure in practice.

Methods: A systematic review was undertaken. Two blind reviewers assessed the methodology of relevant publications into a four-point classification system adapted from multiple sources. The association between study design classification and reported results was examined using linear regression with clustering based on screening tool and robust variance estimates with point estimates of Youden Index (= sensitivity + specificity - 1) as the dependent variable. Meta-analysis was then performed pooling data from prospective studies.

Results: Thirty-five publications met inclusion criteria, containing 51 evaluations of fall risk screening tools. Twenty evaluations were classified as retrospective validation evaluations, 11 as prospective (temporal) validation evaluations, and 20 as prospective (external) validation evaluations. Retrospective evaluations had significantly higher Youden Indices (point estimate [95% confidence interval]: 0.22 [0.11, 0.33]). Pooled Youden Indices from prospective evaluations demonstrated the STRATIFY, Morse Falls Scale, and nursing staff clinical judgment to have comparable accuracy.

Discussion: Practitioners should exercise caution in comparing validity of fall risk assessment tools where the evaluation has been limited to retrospective classifications of methodology. Heterogeneity between studies indicates that the Morse Falls Scale and STRATIFY may still be useful in particular settings, but that widespread adoption of either is unlikely to generate benefits significantly greater than that of nursing staff clinical judgment.

Skills in LLB threshold learning outcomes and competency standards for entry-level lawyers – a comparison using CAQDAS

This exploratory study analysed the Threshold Learning Outcomes ("TLOs") specified in the Bachelor of Laws Learning and Teaching Academic Standards Statement December 2010, and the Competency Standards for Entry-Level Lawyers for Practical Legal Training, as updated by the Australasian Professional Legal Education Council and Law Admissions Consultative Committee in February 2002 ("NCS"). The qualitative analysis was undertaken using the NVivo computer assisted qualitative data analysis software ("CAQDAS"), to investigate how skills were categorised and defined in each of the documents. The results were then analysed to compare the respective categorisation and definition of skills, and to point to potential complements, overlaps, conflicts, gaps, or blind spots, between the TLOs and the NCS. The findings, and the methodology adopted, might provide insights for future instructional design, content, and delivery of Practical Legal Training programs, and for future reviews of the TLOs and NCS.

Effects of a multivitamin, mineral and herbal supplement on cognition and blood biomarkers in older men: a randomised, placebo-controlled trial

OBJECTIVE: Nutritional and vitamin status may be related to cognitive function and decline in older adults. The aim of this study was to investigate the effects of nutritional supplementation on cognition in older men. METHOD: The current study was an 8-week, placebo-controlled, double-blind investigation into the effects of a multivitamin, mineral and herbal supplement (Swisse Men's Ultivite®, Swisse Vitamins Pty Ltd, Melbourne, Australia) on cognitive performance in older men. Participants were 51 male individuals aged between 50 and 74 years, with a sedentary lifestyle. Cognitive performance was assessed at baseline and post-treatment using a computerised battery of cognitive tasks, enabling the measurement of a range of attentional and memory processes. Blood measures of vitamin B(12) , folate and homocysteine were collected prior to and after supplementation. RESULTS: The results of this study revealed that contextual recognition memory performance was significantly improved following multivitamin supplementation (p < 0.05). Performance on other cognitive tasks did not change. Levels of vitamin B(12) and folate were significantly increased with a concomitant decrease in homocysteine, indicating that relatively short-term supplementation with a multivitamin can benefit these risk factors for cognitive decline. CONCLUSION: Findings from this study indicate that daily multivitamin supplementation may improve episodic memory in older men at risk of cognitive decline.

Deconstructing pedagogies of professional practice and learning for police officers.

This research applied qualitative and narrative methodology to investigate police officers' professional practice and learning. Analysis of the data revealed three thematic frameworks of power-knowledge relations, practice and knowledge, and gender and (dis)embodied practice that harboured doubtful matters (aporias) and blind spots (lacunae). The potential for change and the possibility of different perspectives and new learning was evident. Paradigmatic shifts in thinking, learning and practice are needed for police officers to develop reflexive practice that is social, relational, agential, and embodied, however, limitations and constraints exist based on the strength and resilience of dominant pedagogies influenced by social, cultural, institutional and occupational practices and discourses.

Blind equalization of nonirreducible systems using the CM criterion

We address the blind equalization of finite-impulse-response (FIR) and multiple-input multiple-output (MIMO) channel systems excited by constant modulus (CM) signals. It is known that the algorithms based on the CM criterion can equalize an FIR MIMO system that is irreducible. The irreducible condition is restrictive as it requires all source signals to be received at sensors simultaneously. In this paper, we further show that the CM property of signals can be exploited to construct a zero-forcing equalizer for a system that is nonirreducible. Simulation examples demonstrate the proposed result.

The effect of topical wheatgrass cream on chronic plantar fasciitis: a randomized, double-blind, placebo-controlled trial

Objectives: To investigate the efficacy of a topical wheatgrass cream for improving pain and function in patients with chronic plantar fasciitis.

Design: Randomized, double-blind, placebo-controlled trial.

Setting: Eighty participants with chronic plantar fasciitis were randomly assigned to a treatment group (wheatgrass cream) or a control group (placebo cream). All participants applied a cream twice daily for 6 weeks. Follow up was conducted at 6 and 12 weeks.

Main outcome measures: Visual Analogue Scale (VAS) for daily first-step pain and the Foot Health Status Questionnaire (FHSQ) for overall foot function. Secondary measures of foot posture, calf muscle strength and range of ankle dorsiflexion were also assessed.

Results: No significant differences were found between groups with respect to main outcomes of first-step pain or foot function at any time. Both groups improved significantly from baseline to 6 weeks, and these improvements were maintained at 12 weeks.

Conclusions: The topical application of wheatgrass cream is no more effective than a placebo cream for the treatment of chronic plantar fasciitis.
