Mode Matters!: Undergraduate Nursing Students’ Perceptions of Test-Preparation and Test-Taking Strategies for Computer Based Testing
No full textBackground: Until recently, computer-based testing (CBT) has not been widely used in Canadian nursing programs and traditional paper-based testing has been the predominant testing modality. However, since the COVID-19 pandemic, many nursing schools very quickly adapted to remote evaluation strategies including rapid CBT implementation. There is limited literature surrounding how nursing students prepare for and what test-taking strategies are used when completing CBTs as opposed to traditional paper-based exams.
Purpose: The purpose of this study was to gain an understanding of undergraduate nursing students’ perceptions of test-preparation and test-taking strategies specific to CBT. Sharing this knowledge may contribute to the body of literature and serve as a foundation for further research.
Method: Through purposive sampling, this qualitative study was implemented, and data collected using online surveys and semi-structured focus groups. Data was analyzed by thematic analysis.
Results: Three themes were generated: double duty, test-taking tribulations, and repeat exposure. Findings including test-preparation learnings, test-taking challenges, and recommendations for CBT are discussed.
Conclusion: CBT poses both challenges and learning opportunities for students. Exposing students to CBT may increase their awareness of effective test-preparation and test-taking strategies which may positively contribute to how they prepare for future computerized exams.articl

No full textExplorations of structure and choice in taxing capital gains: New Zealand tax experts' perspectives
No full textThis study explores the key issues, aspects, and attributes concerning capital gains tax (CGT) to enable the formulation of policy guidelines that might be used if a CGT were considered in New Zealand. It contends that the development of the New Zealand’s policy on taxing capital gains has continued in a somewhat ad hoc and inconsistent fashion. The lack of a uniform approach to capital gains taxation has resulted in detailed, but complex, legislation which leads to “policy inconsistencies and unintended incentives built into the tax structure” (Oliver, 2001, pp. 80 – 81). The study bridges the divide between theoretical analysis of CGT and implementation issues on operating a CGT. It attempts to address one primary research question and an associated secondary question. The primary research question is: should capital gains be taxed more comprehensively than at present? As a start, it examines the two important issues surrounding income definition and the capital/income distinction. In this regard, the research first attempts to identify the definition(s) of capital gains from the New Zealand perspective(s). This is followed by investigating the key areas of the tax system in order to seek the best way of taxing capital gains. This study also attempts to address the secondary research question, i.e., why (or why not) do the tax experts favour (or oppose) a comprehensive CGT? In this respect, this study identifies 23 factors/issues that are related to the tax experts’ attitudes towards a particular form of a CGT model (i.e., current hybrid approach, a realisation-based CGT or an accrual-based CGT). A mixed-methods design has been adopted in this study involving both a quantitative (survey) and a qualitative (interview) method in analysing the data to determine the tax experts’ overall perceptions of a CGT in New Zealand and the CGT adoption factors which influenced them. One important finding of the comparative analyses was that all tax experts generally agreed that the lack of a comprehensive CGT could provide more significant tax planning opportunities. However, many tax experts did not support the comprehensive income concept as they disagreed with the benefits derived from the gains in horizontal equity through adopting a CGT. This study has identified several important policy issues and reviewed their implication for the adoption of a CGT in New Zealand. The finding of the study revealed that the tax experts strongly supported the exemption of the gains on disposal of a taxpayer’s main residence and the tax preference for inflation adjustment. Another important policy issue is the implementation of an accrual-based CGT. Most tax experts considered a realisation-based CGT would be better than an accrual one. In particular, they were concerned about the liquidity problems and the compliance costs involved in an accrual-based CGT regime i.e., the annual valuation of all assets. These findings represent a first step towards a theoretical CGT framework. It is hoped that the knowledge gained in this study would give a greater understanding into the practical decision-making process that could result in a better public acceptance for a tax reform
Mia Couto and the enchantment of rain
No full textIn his preface to Rain and Other Stories, Mia Couto refers to the remaking of the world following the Mozambican civil war: ‘we soak our faces in this rain of hope, this water of benedreamtion’. Pluvial rain, as Nuttall terms it, can bring huge destruction, as can drought, its absence. Scholars have insisted on the agency of water, including African ecocritics who argue for an ‘animist conception of the world’ which transposes and transgresses boundaries and identities. Garuba specifically refers to the ‘persistent re-enchantment of the world’ whereby the ‘rational and scientific are appropriated and transformed into the mystical and magical’. This article explores the range of roles, agentic and enchanted, which Couto accords rain in his stories. Although he rejected the label ‘magic realist’, his translator Chabal argues that in his stories the fantastic ‘transmutes the fictitious into the factual’ so that ‘all boundaries are put into question’: between past and present, far and near, material and spiritual. And he seeks to regain the ‘brotherhood’, the ‘relation’, the ‘link between nature and humanity’. Ashcroft says Couto’s vision as a writer is to ‘give back to the word its divine power … the power to enchant things, be these trees, birds, or landscapes’. Samuelson too claims that Couto’s stories ‘invoke an enlivening ecocritical method’ that draws readers into a ‘sacred web’, an ‘indivisible body, an ‘interconnected world’. While the notion of enchantment is not unproblematic, the interconnections it entails between human and environment, material and spiritual, generate a receptive matrix in which to understand and recognise the agency of rain.
Contribution: This article engages with ecocritical readings of the stories of Mia Couto by examining his treatment of rain and his approach to the issue of enchantment. It thus contributes to criticism of his work as well as to the growing field of ecocriticism in this country
The effects of fiscal consolidation in the OECD
No full textDespite the current recession in many parts of the OECD, fiscal consolidation is likely in many OECD economies in the 1990s. The author asks: is fiscal consolidation in the OECD in a period of low growth a recipe for global stagnation? In particular, what effects are likely in developing countries? The author starts with an overview of cuts in the U.S. fiscal deficit proposed by the Clinton administration and the extent to which European governments must cut fiscal deficits between now and 1997 to satisfy deficit targets in the Maastricht Treaty. How changes in fiscal policy are transmitted within an economy and between that economy and the rest of the world depends on whether those changes lead to permanent or temporary changes in government saving; whether they are implemented through government spending or taxes; and whether the taxes fall on households or firms. The main channels of transmission are through changes in: agents'expectations about future taxes, interest rates, exchange rates, and economic activity. The author uses the MSG2 multicountry models to quantify the ramifications of those changes. He concludes, among other things, that fiscal contraction in the OECD will probably lead to slower growth over the next several years. But the current and likely paths of fiscal policy are such that deficit reduction programs may have stimulating effect in the short run, as long as future fiscal contraction is credible. And fiscal deficit reduction will probably increase long-run output in the OECD through its effects on savings and investment. Finally, growth in the developing countries (at least total growth) may not be impaired at all by fiscal consolidationin the OECD. The negative effects of fiscal contraction will occur through lower net exports of non-OECD economies. For developing countries with open capital markets, the initial reduction in demand through lower exports can be offset by the reduction in interest rates following an inflow of capital from the countries with contracting fiscal policy. A significant decline in real global interest rates is likely to increase growth in developing countries that are debt-constrained, either directly (through private capital inflows) or indirectly (by relaxing the balance of payments constraint, allowing more resources to be channeled to domestic investment needs).Economic Theory&Research,Economic Stabilization,Environmental Economics&Policies,Banks&Banking Reform,Macroeconomic Management
