Engineering education is an emerging field of research. Due to its applied nature, recent theoretical developments have been followed by empirical evidence and interdisciplinary research. The present study attempted to describe the team roles assumed by members of project teams composed of young engineering students. The study was conducted in Pakistan by using the Belbin Team Role Self Perception Inventory. It was found that young Pakistani engineers assumed the roles of implementer, coordinator, shaper and team worker. This study attempts to understand role choices through the framework of national cultural dimensions proposed by Hofstede and engineering education culture offered by Godfrey and Parker. The study strongly recommends that engineering curriculum should incorporate activities which could foster creativity among engineers. Moreover, engineering students should be motivated to innovate through collaboration in a problem and project based environment, which is seriously lacking in engineering education of Pakistan. 相似文献

Fundraising techniques used by charities can enhance or diminish public trust. The dangers of questionable and over-aggressive fundraising practices are very real. In particular, in the UK, the ‘Olive Cooke affair’ in 2015 triggered a highlevel examination of fairly widespread dubious practices. In this article, the reflections of a key actor on the events surrounding the affair, and subsequent fallout, are examined. It is argued that this whole saga has the potential to encourage the development of a charity sector that is more trusted by the public; a sector that has stepped back from the abyss. 相似文献

This study investigates the impact of MiFID II on the London Stock Exchange. We find that a tick-size reduction leads to lower bid–ask spreads, lower trade values, reduced cost of trading at and beyond the best bid-offer, an acceleration of quote updates, an increase in aggressive trades and a reduction in price impact. Increased tick size widens spreads and increases trading costs. Step functions reveal that liquidity adjusts opposite to the tick change. To determine if impacts are proportional, we identify potential functions that predict cost changes with tick updates, implying that traders adjust their trade sizes according to the new tick levels. 相似文献

Abstract This study investigates the risk inherent in defined contribution (DC) pension plans on an individual and aggregate basis, based on U.S. data. Our aim is to gain insight into the consequences of a DC pension scheme becoming the predominant pillar of retirement income for an entire society. Using the stochastic simulated output of a DC flexible age-of-retirement model, we first determine the optimal investment strategies. We then examine the demographic retirement dynamics of an entire population of DC pension plan participants. We observe that even for the most risk-averse plan members there is a high level of uncertainty in an individual’s age at retirement. At the aggregate population level, we find that this uncertainty does not get dampened to any great extent by a diversification effect. Instead, the central role played by the market in determining retirement dates results in significant variation in the dependency ratio (the ratio of retirees to workers) over time. In addition, an attempt to ameliorate the outcome by introducing additional realistic features in the DC population modeling did little to dampen this volatility, which suggests that countries dominated by DC schemes of this type may, over time, be exposed to significant risk in the size of its labor force. 相似文献

We identify forward-looking statements (FLS) in firms’ disclosures to distinguish between “forecast-like” (quantitative statements about earnings) and “other”, or non-forecast-like, FLS. We show that, like earnings forecasts, other FLS generate significant investor and analyst responses. Unlike earnings forecasts, other FLS are issued more frequently when uncertainty is higher. We then show that earnings-related FLS are more sensitive to uncertainty than quantitative statements, suggesting that managers are more likely to alter the content than the form of FLS when uncertainty is higher. Our study indicates that incorporating other FLS into empirical measures provides a more comprehensive proxy for firms’ voluntary disclosures. 相似文献

The electric utility industry is in transition but needs to move even faster if the country is to meet its emissions goals. The industry has historically moved cautiously, but policies and regulatory approaches must avoid unintentionally reinforcing the status quo. Incentive‐oriented policies and redesigned regulations must balance environmental sustainability with economic sustainability. The authors draw on well‐established corporate finance principles to guide more effective policies. Shareholder‐focused utility executives must make investments conditioned by three elements: (1) the return on equity the utility can expect to make on each project; (2) the investors' required return on equity capital for each project; and (3) the size of the investment. The well‐established economic value added (EVA) model can assist policy analysis: V=(r‐k)I; where V is the shareholder value created, r is the return on equity, k is the return investors require if they are to invest in the stock, and I is the scale of the project. Any new incremental V translates into higher stock prices. All three elements of their model (i.e., risk, return, and scale) require attention by regulators and policymakers to create value for shareholders. The authors show how the right state policies could create powerful incentives for shareholder focused utility executives to support such transitions. 相似文献

This paper adapts the hybrid method, a combination of the Laplace transformation and the finite-difference approach, to the pricing of barrier-style options. The hybrid method eliminates the time steps and provides a highly accurate and precise numerical solution that can be rapidly obtained. This method is superior to lattice methods when trying to solve barrier-style options. Previous studies have tried to solve barrier-style options; however, there have continually been several disadvantages. Very small time steps and stock node spaces are needed to avoid undesirable numerically induced oscillations in the solution of barrier option. In addition, all the intermediate option prices must be computed at each time step, even though one may be only interested in the terminal price of barrier-style complex options. The hybrid method may also solve more complex problems concerning barrier-style options with various boundary constraints such as options with a time-varying rebate. In order to demonstrate the accuracy and efficiency of the proposed scheme, we compare our algorithm with several well-known pricing formulas of barrier-type options. The numerical results show that the hybrid method is robust, and provides a highly accurate solution and fast convergence, regardless of whether or not the initial asset prices are close to the barrier. 相似文献

We extend prior research on the value relevance of accounting information for loss-making firms by allowing the coefficient of book value to vary across three distinct set of loss-making firm observations in our valuation model. Our key findings are, first, that book value is a less important determinant of equity value for either high R&D-intensive firms or dividend-paying firms, relative to firms with low R&D-intensity and zero dividends. Prior literature suggests that book value is a strong indicator of firm value for loss-making firms. This reasoning stems from book value's role as: (i) a proxy for the value of the possibility of abandoning or adapting the firms' net assets; and/or (ii) a proxy for expected future normal earnings. Our work suggests that this prior literature does not fully capture the valuation role of book value for loss-making firms. Second, we also find that dividends are value relevant, but generally only when the valuation role of book value is contextualised by allowing its coefficient to vary across high R&D-intensive firms, and dividend-paying, loss-making firms. 相似文献
