The effect of social conflict on relationship loyalty in business markets

This study examines the impact of perceived social conflict on existing buyer-seller relationships. The results indicate that as the level of social conflict increases, perceptions about the loyalty of the relationship decrease. Perceived importance of the relationship had no impact on conflict or relationship loyalty. Ramifications of these findings for selling, sales management, and sales training are discussed.     

A phenomenographic study of Greek primary school students’ representations concerning technology in daily life

The present research investigated and studied students’ representations about daily life technologies, in a prospect of studying technology in Greek primary education. In the research participated 60 Greek primary school students aged 9 to 12 years old. Research data were collected through semi-structured, personal, clinical-type interviews. Each interview investigated student’s conceptions and views about the following thematic areas: the concept of technology, daily life technologies, technological change, and the impact of technology use in everyday life. Data analysis revealed that the majority of students equated technology with modern tools and appliances, especially with computers, TV, mobile phones, satellites and other micro- and macro-technologies, whereas experience based technologies (de Vries, Technology education: Beyond the “technology is applied science” paradigm. J. Technol. Edu. 8 (1996), 7) have been hardly recognized by them as technology. Also students’ representations can be categorized either as technology-oriented representations, which focus on a collection of technical means without reference to humans, or as human-oriented representations, focused on technical means with substantial reference to human needs and activities. Depending on these types of representations, students seem to conceive differently the nature of the problems, which they recognize that the wide use of technology causes mainly to the environment and the responsibility of the user for these problems. Moreover, it seems that the concept of technological change is a quite difficult one for the students. In order to help students form adequate representations about daily life technology and technological change an appropriate teaching approach was designed on the basis of these students’ representations.

电子货币的特征及其理论基础分析

相对于传统货币，电子货币具有准货币、发行主体多元化、流通速度快、面临新风险等特征。电子货币的一些特征符合新货币经济学和内生货币供给理论所描述的经济状态。基于新货币经济学和内生货币供给理论对电子货币进行分析，得出结论：在电子货币完全流通的情况下，中央银行将逐渐丧失货币的垄断发行权，商业银行与其他非银行金融机构甚至非金融机构均可以发行电子货币，通货膨胀有可能不复存在，传统意义上的货币可能消失。     

Compliance Costs for Employers: UK PAYE and National Insurance, 1995–96

This paper, based upon research financed by the Inland Revenue and the Contributions Agency of the DSS, presents calculations of the compliance costs for employers of PAYE and National Insurance in 1995–96. Total costs are estimated to have been of the order of £1.3 billion. The costs are very unequally spread across employers, whether measured per employee or per pound of tax raised. They are particularly high for small new employers. For the largest employers, these costs may be offset by the cash-flow benefits of acting as tax collectors. The composition of labour and other costs is calculated and estimates are made of compliance costs under various payroll ‘technologies’. The main determinants of compliance costs, for an employer, are analysed using weighted least-squares regression analysis. Finally, some policy implications are considered.     

Rural telephone in Indonesia and Thailand: Social and economic benefits

This article considers the need for telecommunications in the rural areas of Indonesia and Thailand. Using the findings from questionnaire surveys in the two countries, the authors examine how the telephone is used when limited facilities are available, the effects of telephone service in terms of improved communication and work efficiency, and the consequences of not having access to a telephone     

Intraday Value at Risk (IVaR) using tick-by-tick data with application to the Toronto Stock Exchange

This paper investigates the use of tick-by-tick data for intraday market risk measurement. We propose a method to compute an Intraday Value at Risk based on irregularly spaced high-frequency data and an intraday Monte Carlo simulation. A log-ACD–ARMA–EGARCH model is used to specify the joint density of the marked point process of durations and high-frequency returns. We apply our methodology to transaction data for three stocks actively traded on the Toronto Stock Exchange. Compared to traditional techniques applied to intraday data, our methodology has two main advantages. First, our risk measure has a higher informational content as it takes into account all observations. On the total risk measure, our method allows for distinguishing the effect of random trade durations from the effect of random returns, and for analyzing the interaction between these factors. Thus, we find that the information contained in the time between transactions is relevant to risk analysis, which is consistent with predictions from asymmetric-information models in the market microstructure literature. Second, once the model has been estimated, the IVaR can be computed by any trader for any time horizon based on the same information and with no need of sampling the data and estimating the model again when the horizon changes. Backtesting results show that our approach constitutes reliable means of measuring intraday risk for traders who are very active in the market.

高校后勤社会化改革面临的问题与对策

高校后勤工作既有经济特点,又有教育特点,高校后勤社会化并不是简单由原来"内部一体化"组织改革成"市场化"组织,而是完全按照市场规律来组织后勤服务的运作和管理。所以,在高校社会化改革的过程中,必须按照有利于高校发展和有利于后勤工作发展的双赢思想实施高校后勤社会化改革方案。
