MATLAB在《航天器控制》多媒体教学的彻底应用

《航天器控制》是我国航天航空院校一门重要的专业课,是本科生后续课程和研究生课程的基础,它在专业课程体系中占有重要地位。由于该课程具有较强的工程背景,所以数学模型复杂,再加上目前专业课的学时不断压缩,因此如何在较短的时间内,提高教学效率和效果,已经成为教师讲授该门课程时不得不考虑的一个重要问题。     

我国创业板上市公司治理问题研究

由于我国证券市场创业板上市公司股权结构具有控股股东持股比例相对较低的特点,这将产生不同于主板上市公司的剥夺型公司治理问题。要解决这一问题,就必需完善保护中小股东的有关法规,加强执法力度,建立声誉约束机制,并加大对失信行为的处罚力度。     

Signing trades and an evaluation of the Lee–Ready algorithm

We use techniques developed to analyze the Supply Curve in liquidity models in order to analyze the accuracy of the Lee and Ready algorithm, both for highly liquid and relatively liquid stocks. Through the use of order book data combined with tick data, we are actually (somewhat tediously) able to tell whether or not a given trade is buyer or seller initiated. For those trades where such knowledge is certain, the accuracy of the Lee and Ready algorithm is not as accurate as has been assumed previously. We can essentially prove that the Lee and Ready algorithm is always at least 55% accurate, and is around 61% accurate for highly liquid stocks (i.e., the top 50 of the S&P 100).     

Should multivariate early warning systems for banking crises pool across regions?

Most extant work on prediction of banking crises has utilised global samples, which are in turn dominated by observations from middle-income countries, and rely on a single estimator. However, economic and financial structures as well as the pattern of shocks may differ substantially across regions, while a range of specifications is desirable to check robustness. Accordingly, in this paper we test the implicit pooling assumption in earlier multivariate work on Early Warning Systems using both logit and binary recursive tree specifications separately for crises in Asia and Latin America, as well as the pooled sample. Results suggest markedly different crisis determinants across regions, implying global samples are inappropriate.     

The market research contribution to new product failure and success

This paper examines the use made by management of market research data in the evaluation of new product development (NPD) projects. Stressing the need for a systematic approach to NPD the paper sets out four brief case histories, the products being Crocodillo, Paul Masson wine, the Prudential's Holburn UK Unit Trusts, and Golden Wonder's Preludes. These case histories illustrate both the value of a systematic approach to NPD by building up a market research programme and also the limitations of market research data which cannot alone be any guarantee of success.     

Vertical Disintegration: A Dynamic Markovian Approach

In a model where a monopolistic downstream firm (assembler) negotiates simultaneously with each of its intermediate‐input suppliers the prices of the complementary components which enter its product, we analyze the process by which the assembler separates from its suppliers as a Markov Perfect equilibrium. Due to a negative strategic effect (the prices and profits of independent suppliers decrease when their number increases), the assembler’s marginal return from keeping an upstream subsidiary is lower than the market value of an independent supplier. Separation is immediate when the downstream firm’s initial number of upstream subsidiaries is below a critical level. It is progressive in the reverse case and eventually leads to a mixed strategy whereby the assembler keeps all the remaining subsidiaries with some probability, and sells all them off in one go with the complementary probability.     

Changing Perspectives on the Factors of Production

Envy is a complex emotion that influences the behavior of envious and envied individuals. Because envy can imply ill will, discontent or dislike of the envied individual who possesses something that the envious individual desires, or aspiration to emulate the envied position, it can lead the envious individual to undertake costly efforts to reduce the gap between the envied situation and his own situation. The envious individual can seek either to damage or match the situation enjoyed by the envied individual. In return, the envied individual can adopt either envy-appeasing strategies or envy-arousing strategies. We argue that these costly envy-related behaviors impede or stimulate economic development.

Ten Years of IFRS: Practitioners’ Comments and Suggestions for Research

A growing body of research is evaluating the widespread adoption of IFRS. The aim of this paper is to link the findings of academic research with feedback from practitioners about whether the hoped‐for benefits of adoption are being realised. In addition, we present comments from practitioners about IFRS research and we identify areas that may be usefully explored in future research. Our review complements the papers included in part one of this forum (Australian Accounting Review, September 2012), which describe events in the development of global standards over the last 10 years.
