Students’ conceptions of learning in the context of an accounting degree

Students' conceptions of learning (CoL) play an important role in the learning process leading to the development of generic skills. This paper investigates whether CoL of accounting students can be developed by incorporating high-level cognitive skills progressively within the accounting curriculum. First, the study explored, using phenomenography, the variation in accounting students' CoL. The findings highlighted some nuances in accountings students' CoL and that lower-order CoL were prevalent among accounting students. However, more (less) third-year students than second-year students adopted higher- (lower-) order CoL. Upon examining the learning objectives, teaching methods and assessment of all units comprising the accounting major of the host university, evidence was found that CoL are progressively developed and shaped, albeit in a limited way, based on the levels of cognitive domain emphasised within the curriculum. The findings highlight the need for accounting educators to take a whole of the programme approach to developing higher-order CoL.     

Debt markets and corporate debt structure in an emerging market: The South African example

This is a first attempt at gauging the effects of corporate public debt issuance on the debt structure, risk profile and valuation of firms in an emerging market. We find that financial services firms, along with government institutions, are important early supporters of an organized public debt market. Firms in this market use equity, public debt and private debt funds simultaneously as need be. Consistent with predictions of the corporate debt structure literature, public debt-issuing firms are larger, older, more profitable, and less informational opaque than non-public debt-issuing firms. Moreover, public debt-issuing firms experience significant reductions in both overall and systematic risks, and incur lower cost of capital following issuance than non-public debt issuers. These and other findings of the study suggest deepening national debt markets can be a fruitful financial market development exercise for emerging markets.     

An Institutional Theory Perspective on Corruption: The Case of a Developing Democracy

The purpose of this paper is to use quantitative data to describe corruption in the SANPS, and use Luo's ( 2005 ) institutional theory to gain insights into how corruption develops and remains entrenched despite the introduction of anti‐corruption legislation. A total of 1,500 questionnaires were distributed to public servants in nine provinces, but predominantly in Kwa Zulu Natal and Gauteng. There were 702 returned giving a response rate of 47%. We conclude that the findings discussed in this paper lend support for Luo's theoretical model being able to provide insight into the development of corruption, its consequences and possible remedies.     

Comparative analyses of published cost effectiveness models highlight critical considerations which are useful to inform development of new models

Abstract

Background: Comparative analyses of published cost effectiveness models provide useful insights into critical issues to inform the development of new cost effectiveness models in the same disease area.

Objective: The purpose of this study was to describe a comparative analysis of cost-effectiveness models and highlight the importance of such work in informing development of new models. This research uses genotypic antiretroviral resistance testing after first line treatment failure for Human Immunodeficiency Virus (HIV) as an example.

Method: A literature search was performed, and published cost effectiveness models were selected according to predetermined eligibility criteria. A comprehensive comparative analysis was undertaken for all aspects of the models.

Results: Five published models were compared, and several critical issues were identified for consideration when developing a new model. These include the comparator, time horizon and scope of the model. In addition, the composite effect of drug resistance prevalence, antiretroviral therapy efficacy, test performance and the proportion of patients switching to second-line ART potentially have a measurable effect on model results. When considering CD4 count and viral load, dichotomizing patients according to higher cost and lower quality of life (AIDS) versus lower cost and higher quality of life (non-AIDS) status will potentially capture differences between resistance testing and other strategies, which could be confirmed by cross-validation/convergent validation. A quality adjusted life year is an essential outcome which should be explicitly explored in probabilistic sensitivity analysis, where possible.

Conclusions: Using an example of GART for HIV, this study demonstrates comparative analysis of previously published cost effectiveness models yields critical information which can be used to inform the structure and specifications of new models.     

Economic evaluation for the US of nab-paclitaxel plus gemcitabine versus FOLFIRINOX versus gemcitabine in the treatment of metastatic pancreas cancer

Background: Nab-paclitaxel plus gemcitabine (NAB-P?+?GEM) and FOLFIRINOX have shown superior efficacy over gemcitabine (GEM) in the treatment of metastatic pancreatic ductal adenocarcinoma (mPDA). Although the incremental clinical benefits are modest, both treatments represent significant advances in the treatment of a high-mortality cancer. In this independent economic evaluation for the US, the aim was to estimate the comparative cost-utility and cost-effectiveness of these three regimens from the payer perspective.

Methods: In the absence of a direct treatment comparison in a single clinical trial, the Bucher indirect comparison method was used to estimate the comparative efficacy of each regimen. A Markov model evaluated life years (LY) and quality-adjusted life years (QALY) gained with NAB-P?+?GEM and FOLFIRINOX over GEM, expressed as incremental cost-effectiveness (ICER) and cost-utility ratios (ICUR). All costs and outcomes were discounted at 3%/year. The impact of parameter uncertainty on the model was assessed by probabilistic sensitivity analyses.

Results: NAB-P?+?GEM was associated with differentials of +0.180 LY and +0.127 QALY gained over GEM at an incremental total cost of $25,965; yielding an ICER of $144,096/LY and ICUR of $204,369/QALY gained. FOLFIRINOX was associated with differentials of +0.368 LY and +0.249 QALY gained over GEM at an incremental total cost of $93,045; yielding an ICER of $253,162/LY and ICUR of $372,813/QALY gained. In indirect comparison, the overall survival hazard ratio (OS HR) for NAB-P?+?GEM vs FOLFIRINOX was 0.79 (95%CI?=?0.59–1.05), indicating no superiority in OS of either regimen. FOLFIRINOX had an ICER of $358,067/LY and an ICUR of $547,480/QALY gained over NAB-P?+?GEM. Tornado diagrams identified variation in the OS HR, but no other parameters, to impact the NAB-P?+?GEM and FOLFIRINOX ICURs.

Conclusions: In the absence of a statistically significant difference in OS between NAB-P?+?GEM and FOLFIRINOX, this US analysis indicates that the greater economic benefit in terms of cost-savings and incremental cost-effectiveness and cost-utility ratios favors NAB-P?+?GEM over FOLFIRINOX.     

Human resource development and growth: improving access to and equity in the provision of education and health services in South Africa

This paper demonstrates the importance of improving access to and equity in the provision of essential services such as education and health for enhancing human development. A major constraint to accelerating and sustaining economic growth in South Africa is the shortage of skilled human resources. Human capital formation (through appropriate education, training and health) is vital for growth. However, for sustained growth to reduce poverty and unemployment, human capital of a ‘higher order’ than the system is currently producing, in both quantitative and qualitative terms, must be generated. The paper reviews progress in the education and health sectors and identifies the challenges. It stresses the need for policy makers to recognise the link between education and health outcomes and the provision of clean water, adequate sanitation, cheap and accessible transport and effective nutrition programmes. Addressing only the education and health services is unlikely to lead to optimal outcomes in these sectors.     

Career aspirations of older workers: An Australian study

Global challenges associated with the ageing workforce include lower levels of education and negative attitudes of older workers towards learning and covert age discrimination in the workplace. This report discusses initial findings from a survey of older workers employed in regional areas in Australia. The older workers surveyed were predominantly blue collar with low levels of formal education. Contrary to the stereotypical views, there were few attitude differences between older (>40 years) and younger workers (≤40 years). However, gender, education level and job type had a greater impact on attitudes in the older workers when compared to their younger colleagues.     

Institutional isomorphism and whistle-blowing intentions in public sector institutions

Over the years the new institutionalism in public sector analysis has contributed significantly to our understanding of the dynamics of public sector institutions. While it has moved research away from behavioural explanations to recognizing political and cultural contexts, the focus on public sector institutions has been minimal. This research examines, by self-report questionnaire from employees in two government organizations, how institutional mechanisms shape whistle-blowing intentions within the context of a developing country. Despite the country context, findings from this study are encouraging in that participants’ intentions to blow the whistle were found, generally, to be strong.     

A Rational Expectations Consistent Measure of Risk: Using Financial Market Data from a Middle Income Context*

Although economic theory assumes that risk is of central importance in financial decision making, it is difficult to measure the uncertainty faced by investors. Commonly used empirical proxies for risk (such as the moving standard deviation of the returns on an asset) are not firmly grounded in economic theory. Risk measures have been developed by other studies, but these are often based on subjective weights attaching to a range of objective component indicators, are difficult to replicate and are not strictly consistent with underlying theory. The contribution of this article is to develop a methodology to construct rational expectations consistent empirical risk measures. It has the advantages of being explicitly consistent with economic theory and easily replicable. We illustrate this methodology by specific application to the South African context. The time‐varying risk measure developed in this article is consistent with a rational expectations application of the expectations hypothesis. The constructed measure is a broad one (it includes political risk and peso problems for instance) and reflects investors’ perceptions of systematic risk.
