Masakhane: drumming up an effective music curriculum for pre-service teacher education

The introduction of African indigenous music to a generalist primary teacher education course transcended both cultural differences and personal inadequacies of students. It provided a cohesive bond for promoting the learning of music that is aptly represented by the African concept of masakhane (building together). This research demonstrated the effectiveness of Africa music for promoting cross-cultural music education, thereby providing a worthy model for implementation in other teacher education programs. According to findings from a questionnaire survey and interviews, students reported they were able to more effectively engage with, know, create, perform, teach and experience music through African rather than just the Western music. This experience provided students with new musical knowledge, understandings and skills as well as giving them insights into another musical tradition and culture. Students also perceived Indigenous African music as a source of motivation, interest and enjoyment, thereby promoting their creativity and musical learning. As global citizens, we need to embrace diversity and change not only in our immediate teaching contexts but also in broader educational policy. This curriculum clearly enhanced the effectiveness of music within a teacher education course and by extension has the potential to contribute to a greater professional and public good in education.

Putting pre-service teachers first

One of the recommended principles for classroom practice from the Digital Rhetorics Project is "teachers first", emphasising the need to prioritise the needs of teachers in learning new technologies and understanding their relationship to literacy education (Lankshear, Green, & Snyder, 2000), p.121). While most of my pre-service English Education students use digital technologies for their own purposes and understand the benefits of doing so, it is not always straightforward as to how technology can be effectively utilised in their classroom and for what purposes. This paper reports on work conducted with pre-service English Education teachers in an elective unit that focuses upon digital technologies in secondary classrooms. Using Green's 3D model of literacy as a way of understanding the complex interrelationships between the cultural, critical and operational aspects of literacy, the students experiment with digital technologies such as mobile phones, wikis and blogs.

Video reflection and the formation of teacher identity in a team of pre-service and experienced teachers

This paper discusses a project in which a team of pre-service and experienced teachers, following a teaching development model devised by the authors, reflected on videos of the pre-service teachers teaching literacy. Using a discourse analytic approach, the paper focuses on how teachers' joint reflection contributes to student teacher identity formation. Analysis suggests that reflection, at least in the talk of this team, is a language practice with a distinctive generic structure. Using this structure, participants jointly construct professional teacher identities for themselves and others through the key devices of representation, categorization, evaluation, individualization and inclusion.

The "HEALTH" model- part 1 : treatment program guidelines for complex PTSD

This paper outlines the development and piloting of the “HEALTH” model for treatment of Complex PTSD in clients who have experienced multiple traumas across childhood and adulthood - particularly child sexual abuse and sexual assault in adulthood. As a guideline-based treatment model, HEALTH outlines six stages of intervention: (1) having a supportive therapist; (2) ensuring personal safety; (3) assisting with daily functioning; (4) self-regulation - learning to manage core PTSD symptoms; (5) treating Complex PTSD symptoms; and, finally, (6) having patience and persistence to enable “ego strengthening”. Using a case study approach, we provide both qualitative and quantitative assessment data for the individuals in the study, all of whom displayed numerous pre-treatment symptoms of Complex PTSD. Such programs are different to standard PTSD treatment programs that focus predominantly on core PTSD symptoms of re-experiencing, avoidance and arousal. The results of this study provided support for the use of guideline-based treatment programs that cater specifically for the needs of those who have suffered long-term/multiple trauma experiences by targeting Complex PTSD symptoms.

Doubling fish exports or garment exports : which would benefit the Fijian economy most? Evidence from a computable general equilibrium model

The need to diversify Fiji's export base has been identified as an important avenue for reducing Fiji's vulnerabilities in international trade. This paper poses the question: Doubling fish exports or garment exports: which would be most beneficial for the Fijian economy? To achieve the goal of this paper, the computable general equilibrium model is used, this being at the forefront of research on 'impact studies'. The main finding is that when garment exports and fish exports are doubled, the benefits to the Fijian economy are greater from garment exports, suggesting that the latter has stronger linkages with the rest of the economy. On the basis of this finding, policymakers should divert resources towards sustaining the garment industry whose future is uncertain due to expiring trade agreements and unstable economic policies.

Productivity differential and the relationship between exports and GDP in Fiji : an empirical assessment using the two sector model

This study uses a two-sector model to determine the productivity differential between the export and non-export sectors of Fiji, and the contribution of exports and investment to gross domestic product over the period 1962-2000. Amongst our key results, we find that the productivity differential between the export and non-export sectors is small and statistically insignificant; investment to GDP ratio and weighted exports positively contribute to economic growth in Fiji; and in the abnormal years (years of coups in Fiji) marginal productivity in capital in the non-export sector is lower than in normal years.

Integrated governance : a pre-requisite for sustainable market-orientated development in Bangladesh

Using agriculture input sector as an exemplar, this article assesses Bangladesh's efforts towards a market-oriented development approach. It examines the changing role of the state following the market-based reforms undertaken in this sector and assesses whether the outcomes of the reforms are sustainable. Findings reveal that, although the current move towards a market-oriented approach has led to a shift away from a state-dominated hierarchical structure, it has not been associated with adequate changes in institutional arrangements, safeguards, and regulation. As a result, despite notable achievements of the reforms, the sustainability of these successes is in question. To facilitate participatory, accountable, and sustainable, market-oriented development, the paper proposes an integrated governance model linking state, business, and civil society.

Dynamic recrystallization of austenite in Ni-30 Pct Fe model alloy : microstructure and texture evolution

The microstructure and crystallographic texture development in an austenitic Ni-30 pct Fe model alloy was investigated within the dynamic recrystallization (DRX) regime using hot torsion testing. The prominent DRX nucleation mechanism was strain-induced grain boundary migration accompanied by the formation of large-angle sub-boundaries and annealing twins. The increase in DRX volume fraction occurred through the formation of multiple twinning chains. With increasing strain, the pre-existing Σ3 twin boundaries became gradually converted to general boundaries capable of acting as potent DRX nucleation sites. The texture characteristics of deformed grains resulted from the preferred consumption of high Taylor factor components by new recrystallized grains. Similarly, the texture of DRX grains was dominated by low Taylor factor components as a result of their lower consumption rate during the DRX process. The substructure of deformed grains was characterized by “organized,” banded subgrain arrangements, while that of the DRX grains displayed “random,” more equiaxed subgrain/cell configurations.

Asymmetric recognition of good and bad news at Malaysian capital market : a pre and crisis analysis

The aim of this paper is to analyze the asymmetric recognition of good and bad news on reported earnings of Malaysian-listed firms. The study uses both descriptive and regression analyses to ascertain whether there is a contemporaneous relationship between news (good and bad) and reported earnings. The analysis is based on a sample of 150 firms listed on the Bursa Malaysia Index over a period of 10 years, from 1990 to 2000. Two regression models were adopted based on Basu (1997) and Giner and Rees (2001). The first model aims to capture asymmetric recognition of good and bad news into reported earnings while the latter model is developed to capture both asymmetric recognition of information shock and permanent earnings effect on contemporaneous earnings. The evidence from this study reported the steady increase in earnings per share till 1997. However, a drastic decline was observed for the period 1997 to 1999 because of Asian financial crisis. The findings from the regression model one suggested that the asymmetric recognition of good news was more prominent during the good time compare to bad time and vice versa. The findings from model two also suggested that autoregressive effect of permanent effect was very prominent both for crisis and non crisis periods.

An 'emergent model' for rate of change

Does speed provide a ‘model for’ rate of change in other contexts? Does JavaMathWorlds (JMW), animated simulation software, assist in the development of the ‘model for’ rate of change? This project investigates the transference of understandings of rate gained in a motion context to a non-motion context. Students were 27 14–15 year old students at an Australian secondary school. The instructional sequence, utilising JMW, provided rich learning experiences of rate of change in the context of a moving elevator. This context connects to students’ prior knowledge. The data taken from pre- and post-tests and student interviews revealed a wide variation in students’ understanding of rate of change. The variation was mapped on a hypothetical learning trajectory and interpreted in the terms of the ‘emergent models’ theory (Gravemeijer, Math Think Learn 1(2):155–177, 1999) and illustrated by specific examples from the data. The results demonstrate that most students were able to use the ‘model of’ rate of change developed in a vertical motion context as a ‘model for’ rate of change in a horizontal motion context. A smaller majority of students were able to use their, often incomplete, ‘model of’ rate of change as a ‘model for’ reasoning about rate of change in a non-motion context.

Relationship between indices of adiposity obtained by peripheral quantitative computed tomography and dual-energy X-ray absorptiometry in pre-pubertal children

Background/Aim: The study investigated the relationship between indices of adiposity measured by peripheral quantitative computed tomography (pQCT) and dual-energy X-ray absorptiometry (DXA) in pre-pubertal children.

Subjects and methods: DXA-derived per cent body fat (%BF) was measured in 284 boys and 288 girls, aged 7–10 years. Cross-sections of the forearm (n=427) and lower leg (n=560) were obtained by pQCT to measure total cross-sectional area of the limb (Total CSA), Muscle CSA, Fat CSA, %Fat CSA (Fat CSA/Total CSA×100) and muscle density.

Results: Peripheral QCT-derived %Fat CSA in the forearm and lower leg correlated strongly with DXA-derived %BF (r=0.83–0.89, p<0.01) in both boys and girls. However, forearm and lower leg %Fat CSA were higher than whole body %BF by 5% and 10%, respectively. A better prediction of whole-body %BF was achieved by including %Fat CSA, muscle density and height into a hierarchical regression model. Using sex-specific regression equations, 87.7% of the boys and 83.7% of the girls had a predicted %BF within 3% units of the %BF obtained by DXA.

Conclusion: In pre-pubertal children, pQCT measures of adiposity are strongly associated with whole-body per cent body fat. This reproducible method could be an alternative technique to estimate body composition in this population.

Design management methodology to strengthen firm and industry competitiveness in the construction design services export sector

The aim of this research was to investigate strategies deployed by successful construction design-related firms towards achieving high levels of firm competitiveness in international markets. A reflexive capability model, developed through a critical analysis of related internationalisation literature, is composed of three key areas; internationalisation process, market knowledge and design management. Firm reflexive capability is explored through the management of social, cultural and intellectual capital. The concept of reflexivity is borrowed from sociology. Reflexivity is reinterpreted as the ‘firm’s’ ability to be aware, responsive and adaptable to self, market and project needs assessment. A cross case analysis explored the barriers and success factors through three constructs; internationalisation process, design management and market knowledge of three firms. This paper demonstrates that international firm competitiveness is dependent upon the strategic inter-relational management of social, cultural and intellectual capital for maximum advantage of the utilisation and leverage of one form of capital to gain another. This leads to the development of increasing reflexive capability to support internationalisation. An outcome of this research is the identification of the central relation between a level of reflexive capability within the firm and the firm’s level of success in international markets. This research is part of an ongoing program of research on international collaborative practice. A Reflexive Capability Matrix was developed from the findings of one research project and then validated through a second research project (only the capability matrix is presented in this paper though). The reflexive capability approach is appropriate to all firms but what is speculated upon is that the reflexive capability is particularly intrinsic to small to medium sized construction design firms who work globally. A reflexive capability is a characteristic of successful and innovative firms internationalising and working within global models of practice.

The development of a theoretical model for firm design management to support internationalisation processes

A reflexive capability is a characteristic of successful and innovative firms internationalising and working within global models of practice. This paper is the theoretical development to support the paper in this congress “Design Management Methodology to Strengthen Firm and Industry Competitiveness in the Construction Design Services Export sector” where the methodology and results of a cross case analysis of three construction design firms are presented.

Value relevance of accounting information in China pre- and post-2001 accounting reforms

Purpose – This paper aims to investigate whether the accounting reform in China has improved the relevance of China's accounting information. It seeks to investigate the association between earnings and book value of equity to share returns before and after the introduction of the Accounting System for Business Enterprises (ASBE) in 2001 for A- and A&B-share firms.

Design/methodology/approach – The paper employs the return regression model. The pre-ASBE period is designated as 1997 through to 2000, and the post-ASBE period is designated as 2002 through to 2004. All firms listed on the Chinese stock market during the investigation period constitute the sample.

Findings – It is found that accounting information better explains share returns for both A-share firms and A&B-share firms in the post-ASBE period. The paper also finds that the book value of equity for A&B-share firms is incrementally value relevant to that of A-share firms in the post-ASBE period.

Research limitations/implications – Further studies will contribute to understanding how governance mechanisms and liquidity influence the association between accounting information and share returns in the Chinese A-share market.

Practical implications – The findings provide empirical evidence regarding the relevance of accounting information in emerging markets.

Originality/value – The paper contributes to the extant value relevance literature by investigating time periods surrounding the issue of ASBE in 2001 in the Chinese stock market.

Recognition of polyadenylation sites in yeast pre-mRNAs by cleavage and polyadenylation factor

Recognition of poly(A) sites in yeast pre-mRNAs is poorly understood. Employing an in vitro cleavage system with cleavage and polyadenylation factor (CPF) and cleavage factor IA we show that the efficiency and positioning elements are dispensable for poly(A)-site recognition within a short CYC1 substrate in vitro. Instead, U-rich elements immediately upstream and downstream of the poly(A) site mediate cleavage-site recognition within CYC1 and ADH1 pre-mRNAs. These elements act in concert with the poly(A) site to produce multiple recognition sites for the processing machinery, since combinations of mutations within these elements were most effective in cleavage inhibition. Intriguingly, introduction of a U-rich element downstream of the GAL7 poly(A) site strongly enhanced cleavage, underscoring the importance of downstream sequences in general. RNA- binding analyses demonstrate that cleavage depends on the recognition of the poly(A)-site region by CPF. Consistent with in vitro results, mutation of sequences upstream and downstream of the poly(A) site affected 3'-end formation in vivo. A model for yeast pre-mRNA cleavage-site recognition outlines an unanticipated high conservation of yeast and mammalian 3'-end processing mechanisms.
