This paper analyzes the uneven processes underpinning industrial relations policy liberalization in New Zealand, Australia, the UK, and Ireland. Drawing upon 140 elite interviews and building upon ideational comparative political theories, the paper highlights the role of ideas in the policy change process. It identifies how particular ideas can be used to construct policy problems, how these ideas can gain legitimacy through battles with competing ideas, and how policy legacies can influence whether ideas take root. The findings from the comparative case analysis expose a critical difference between “positive legacies” and “negative legacies” to account for different liberalization trajectories.  相似文献

Replanning is often used to optimize results of an activity in an ever changing world. To address the challenge of preparing future engineers for success, a special course was created for all engineering freshmen of the Faculty of Engineering of the University of Porto, in Portugal. Presented as a case study, this special course underwent a careful replanning as a result of several years of experience in teaching practice alongside with a theoretical deepening in pedagogical and technological issues, under the aegis of the action-research methodology. Within the context of the case study course, the mentioned replanning was also based on a theoretical approach that clearly identifies teaching–learning-assessment methodologies that promote regulation from those that foster emancipation, using a specific instrument: a taxonomy of educational processes. The replanning was designed to globally boost results regarding the educational aims of the course such as furthering freshmen’s integration into work environment and preparing them for success by fostering transversal skills (needed for study and work). Technology is seen as a mean of education enrichment as well as a productivity tool. The introduced innovations include fun-but-educational activities, several types of assessment over time and specific technological tools which were critical for the educational impact/achievement of this course. Success is demonstrated by encouraging feedback from the stakeholders, high students’ classifications and a steady reduction in retention. It is advocated that large portions of the reasoning behind the replanning can be extrapolated to other courses.  相似文献

The intermittency of wind power has a decreasing effect on day-ahead spot prices. Data from Germany illustrate this effect and explain the underlying relationships. This short-term price effect leads to an adaptation process in the conventional generation capacity mix. In the long-run, a higher peak load plant share is required to cope with the increasing volatility of the residual demand. The result is an adapted merit-order. This merit-order intersects with an increasingly volatile residual demand curve and leads to a higher price volatility in the power market, which is going to trigger further adaptations. Therefore this article concludes with a list of open research questions, which can be derived from the illustrated relationship. These research questions should be investigated as soon as possible in order to induce the required adaptations in time.  相似文献

Adding to the corporate effect literature, we study the effect of owners on firm performance in a new context, that of venture capital firms (VCs) and the start‐up firms in which they invest. After discussing the effect that VC ownership can have on start‐ups, we estimate that start‐up‐specific, owner (VC), and year effects account for significant variance in performance (26.3 percent, 11.2 percent and 3.7 percent, respectively). The effects of industry and investment stage are not statistically different from zero. We also provide an analysis that separates the owner effect into two components: a selection component—which impacts investment—and a management component—which explains significant variance in performance. By examining the owner effect in a different institutionalized form of governance—that of the start‐up and its relationship to VC owners—our study also contributes to an understanding of the ‘ownership’ effect in the strategy literature more generally.

We present an empirical investigation of the hypotheses that exchange rate uncertainty may have an impact on both the volume and variability of trade flows by considering a broad set of industrial countries' bilateral real trade flows over the period 1980–1998. Similar to the findings of earlier theoretical and empirical research, our first set of results shows that the impact of exchange rate uncertainty on trade flows is indeterminate. Our second set of results provides new and novel findings that exchange rate uncertainty has a consistent positive and significant effect on the volatility of bilateral trade flows, helping us better understand macroeconomic volatility.  相似文献

This paper examines the processes by which individuals work their sense of organizational and professional identity in the aftermath of a professional failure. Drawing on twenty-five interviews carried out with former members of Arthur Andersen who mostly worked for the firm in Canada and the United Kingdom, we investigate interviewees’ identity work ensuing from the breakdown of the firm. Specifically, identity work comprises processes by which individuals reflectively seek to maintain or revise their sense of identification with the AA organization and also with the public accounting profession, along with developing self-understandings regarding causes and consequences ensuing from the firm’s collapse. Our analysis indicates that four interpretive schemes or patterns mainly characterize interviewees’ identity work: disillusion; resentfulness; rationalization; and hopefulness. Each of these patterns can be viewed as conveying a distinct representation of what “truly” happened within AA. In this sense, identity work, sense-making and truth contests are inextricably linked altogether. Moreover, the present paper underlines the pertinence of studying entangled processes of identity work and sense-making in order to better understand how broader social forces or discourses (e.g., commercialization and risk) are experienced and translated by the self in the context of identity-threatening events. That is, the identity work/sense-making nexus constitutes a relevant theoretical anchoring to study the circulation of discourses in society.  相似文献

This study examines whether auditors adjust their effort and pricing decisions for political visibility. We argue, from the behavioural literature, that political visibility will create the need for more justification by auditors. Using data on actual audit fees, hours and billing rates for a sample of New Zealand public sector companies, we find that total audit fees are positively related to the number of press mentions (our proxy for political visibility). Consistent with our expectations we find that audit fees are monotonically related to audit fees. We also find that auditors increase the hours spent on the audit but not billing rates, which further suggests defensive bolstering by auditors.  相似文献

This study examines whether Chief Executive Officer (CEO) equity‐based holdings and compensation provide incentives to manipulate accounting reports. While several prior studies have examined this important question, the empirical evidence is mixed and the existence of a link between CEO equity incentives and accounting irregularities remains an open question. Because inferences from prior studies may be confounded by assumptions inherent in research design choices, we use propensity‐score matching and assess hidden (omitted variable) bias within a broader sample. In contrast to most prior research, we do not find evidence of a positive association between CEO equity incentives and accounting irregularities after matching CEOs on the observable characteristics of their contracting environments. Instead, we find some evidence that accounting irregularities occur less frequently at firms where CEOs have relatively higher levels of equity incentives.  相似文献

Accountability in the control and management of public funds is one of the most sensitive aspects of the activities of government in all democracies. Hence, the 1999 Constitution of the Federal Republic of Nigeria contains provisions relating to legislative powers and control over public funds. However, the required level of accountability in public expenditure has not been achieved in Nigeria. The situation has remained worrisome even though the country does not lack in the appropriate laws and regulation required to bring sanity into the system. Though there have been some bold steps and initiatives in the recent past by the government by strengthening existing institutions and creating new ones with responsibility for fraud and other controls, the issue of weak accounting infrastructure has not been addressed. The paper argues that accountability in public expenditure can more easily be realized within the context of a sound accounting infrastructure and a robust accounting profession and not in the multiplicity of laws and anti-corruption agencies; all of which are reactive in nature. Therefore, the paper reports on the current state of accounting infrastructure in Nigeria, and conclude with an assessment of the existing agencies and current reform initiatives in ensuring accountability in public expenditure in Nigeria.  相似文献

Universities and colleges continue to face constraints related to classroom space and faculty time, thus increasing the need to consider options such as hybrid courses that can leverage available resources. This article discusses the benefits of a hybrid course, as well as its design and implementation at a large, public university. In addition, for universities that use the introduction to risk and insurance course as a significant course for attracting majors, we identify the benefits for students from the use of hybrid courses, such as the variety of materials and activities utilized, as well as the flexibility in scheduling. This information may be useful in marketing the course so that it will be immediately attractive to students.  相似文献
