Architectural design is a knowledge-intensive activity; however, students frequently lack sufficient knowledge when they practice design. Collaborative learning can supplement the students’ insufficient expertise. Successful collaborative learning relies on knowledge sharing between students. This implies that the peers are a considerable design knowledge source for the students. However, students are involved in grade competition. Students may not be willing to share because knowledge is a critical resource for students’ performance. The web technology has been used to facilitate knowledge exchange among students; nevertheless, the convenience of technology may tempt free riding behavior and impede the development of a knowledge sharing culture. The purpose of this exploratory study is to probe whether the peers and a web forum are the students’ primary knowledge source by investigating students’ knowledge sources during the design process. The results demonstrated that (1) studio-mates were a primary design knowledge source for the students, (2) the ill-defined nature of design problems may be the main contributing factor encouraging knowledge sharing behavior, (3) the shared web forum was not a primary knowledge source for the students and did not have a significant influence on the knowledge sharing culture, and (4) we can estimate the knowledge sharing culture in a design studio through investigating students’ knowledge sources. Furthermore, several additional findings and implications are elaborated.  相似文献

Economists at the Federal Trade Commission (FTC) pursue the agency’s competition and consumer protection missions. In this year’s essay, in antitrust, we discuss the new Merger Guidelines, three exclusion cases, and R&D issues in the Thoratec/HeartWare merger and the Google/AdMob merger. In consumer protection, we discuss the FTC’s new rule on debt settlement, our efforts to improve disclosures, and our recent work on appliance energy disclosures.  相似文献

Schoolwork, especially lessons in manual skills is often associated with various ergonomics stresses. These stresses are the result not only of school obligations but also of the physical working environment and inadequate lesson planning. Much can be done in this field if certain approaches are taken into consideration at the work planning stage. Thus we can use certain analytical methods, such as the Method of Temporary Observations (Multi-Moment Method) and OWAS (a method for the evaluation of postural load during work), when positioning stressful lesson factors. This can be done in a relatively simple way in the field of time rationalisation as well as in the field of dimensional work adjustment to pupils. Research results in this paper show that by using a planned directed approach in this field, it is possible to achieve, a higher level of efficiency with normal levels of fatigue.  相似文献

In this research we conduct a systematic and critical review of the literature on executive compensation in Asian countries. We discuss the particular characteristics of executive compensation in Asia in terms of pay criteria, contingency factors, and implications for performance and turnover. We thereby highlight the unique contributions of Asian studies to the mainstream Western research in executive compensation, and call for future research integrating agency theory and the institution-based view in examining pay variances across different institutions.  相似文献

Summary. The purpose of this article is to characterize optimal interest rate rules in the framework of a dynamic stochastic general equilibrium model, and notably to scrutinize the “Taylor principle”, according to which the nominal interest rate should respond more than one for one to inflation. This model yields explicit solutions for the optimal rule. We find that the elasticity of response depends on numerous factors, such as the degree of price rigidity, the autocorrelation of the underlying shocks, or which measure of inflation is used. In general the optimal elasticity of the interest rate with respect to inflation needs not be greater than one.Received: 6 November 2003, Revised: 17 August 2004 JEL Classification Numbers: E5, E52, E58.J.-P.

The authors examine antecedents and consequences of environmental stewardship in frontline business-to-business teams. On the basis of data from members of 34 teams organized into regional networks, they demonstrate the differential impact of team environmental stewardship on customer satisfaction ratings and sales. Furthermore, the results reveal lagged individual-level effects of autonomy and supervisory support on environmental stewardship, as well as lagged group-level effects of past performance. Finally, dispersion models of team stewardship differentially moderate antecedent–stewardship relationships. Whereas within-team consensus strengthens the impact of past satisfaction ratings on subsequent stewardship, between-team consensus weakens the negative impact of past sales.  相似文献

After studying the effects of Louisiana’s post-hurricane “thank you” campaigns, the researchers find expressions of gratitude significantly improve perceptions of Louisiana in the midst of its recovery. Through a national survey conducted November 2006, they find that those who saw or heard a thank you advertisement have more positive attitudes toward the state and its people, a greater willingness to pay a premium for its products, services and travel to the state, and spread positive word-of-mouth, thus justifying the use of public funds to support the campaign. The authors investigate the role of participation on the effectiveness of expressions of gratitude and identify the mediating role of affective commitment in driving the positive results attributed to expressions of gratitude.  相似文献

We would like to insure against the risk that a geometric Brownian motion, correlated with the price process of a certain traded asset, is in a set E at time T. In this paper it is shown that the best action one can take to insure against this risk is to buy a binary option on the traded asset. We give explicit formulas in the case that E is an infinite interval. The setting of all our investigations is the Black-Scholes model.

Existing studies of market orientation have hypothesized that the strength of the market orientation/performance relationship depends on environmental variables such as market turbulence, technological turbulence, and competitive intensity. To date most empirical studies have failed to confirm these hypotheses; however, these studies (1) assumed that performance is a linear function of the achieved level of market orientation and (2) tested whether environmental uncertainty moderates this relationship. A complementary explanation for the impact of environmental variables on a firm’s market orientation arises from studies of organizational behavior that link the need for coordination and control to environmental uncertainty and organizational strategy. Building on this perspective, the authors argue that (1) environmental uncertainty influences the desired level of market orientation and (2) the gap between the desired and achieved levels of market orientation influence business unit performance. The authors test these hypotheses with data collected from multiple respondents in 308 US firms. The data analysis confirms that the desired level of market orientation is a function of market turbulence, competitive intensity, technological turbulence, and innovation strategy. In addition, the desired level of market orientation positively influences the achieved level. Finally, when the achieved level of market orientation is less than the desired level, business unit performance is a negative function of the gap between the desired and achieved levels of market orientation.

This study investigates whether consumers’ perceptions of motives influence their evaluation of corporate social responsibility (CSR) efforts. The study reveals the mediating role of consumer trust in CSR evaluation frameworks; managers should monitor consumer trust, which seems to be an important subprocess regulating the effect of consumer attributions on patronage and recommendation intentions. Further, managers may allay the negative effects of profit-motivated giving by doing well on service quality perceptions. On the other hand, appropriately motivated giving continues to positively affect trust regardless of the performance of the firm on service quality provision.  相似文献
