Are more resources always better for growth? Resource stickiness in market and product expansion

We examine how managerial growth logics combine with financial and human resource slack to influence the short‐term revenue growth of a sample of 112 manufacturing firms drawn from a unique database provided by the Ewing Marion Kauffman Foundation. Our results provide evidence that firms pursuing product expansion logics generally grow more slowly than firms that are not expanding their product base, but that financial slack positively moderates this relationship. We also find that human resource slack enhances short‐term market expansion, but slows down short‐term product expansion. We discuss the implications of these results for resource‐based views of growth. Copyright © 2004 John Wiley & Sons, Ltd.     

The incremental information content of non-US GAAP earnings disclosures: Evidence from UK firms

This paper examines price and trading volume responses in the US equity market to the preliminary earnings announcements (PEAs) in the UK of UK firms listed on US exchanges (e.g., NYSE and AMEX). The inquiry focuses on whether the return forecast error (absolute and squared values) and volume residual (standardized and unstandardized) for each day were significantly different from the average on the day of the earnings announcements (PEA). The most significantly unexpected return occurred the day prior to the Financial Times (FT) announcement. The results suggest prompt volume and price responses to the UK PEAs in the US security market. Excess trading volume occurred the day prior to and the day of the FT release price response occurred on the day subsequent to the PEAs. This may suggests that investors possess differential prior beliefs or likelihood functions in evaluating public disclosure. Consistent with Frost and Pownall [Frost, C., & Pownall, G. (1996), Interdependencies in the global markets for capital and information: The case of Smithkline Beecham plc. Accounting Horizons, 1, 38-57], US investors seem not to be confused by US/UK generally accepted accounting principles (GAAP) differences, and in fact use information about UK GAAP earnings in their valuations and trading decisions. This implies that traders correctly use UK accounting output to the determination of values in setting security prices and arriving at trading decisions. Broadly, these findings support the assumption that disclosures by UK-listed firms in their domestic market influence share liquidity and trading in the US market.     

"知""能"并重 "教""学"并举--师专古代汉语课程教学改革谈

古代汉语课作为高等师范专科学校中文系的一门基础工具课,其教学应该既强调其基础性,又突出其工具性.然而,在该门课程以往的教学实践中却存在知识传授与能力培养失衡的现象.因此,要改革师专古代汉语课程教学,就应从教学内容、教学方法及教学手段等方面入手,在使学生掌握该门课程基本理论和基础知识的同时,切实提高学生理解、分析和运用汉语的能力,做到"知""能"并重、"教""学"并举.     

Estimation of commodity-by-commodity input–output matrices

In this paper we derive a method for the estimation of symmetric input–output tables (SIOTs), which makes it possible to use the commodity technology assumption even when use- and make tables are rectangular. The method also solves the problem of negative coefficients. In the empirical part we derive annual SIOTs in order to evaluate the differences between SIOTs calculated with different methods and the change in technical coefficients over time. Our results, based on data for Sweden, show that the impact of using different technology assumptions is rather large. However, in a factor content of trade application the impact of different technology assumptions does not seem to be very important. Also the size of the changes in the technical coefficients over time is found to be quite large, indicating the importance of calculating SIOTs annually.
