Rafting the River: A Risk Management Expert System for Dynamic Problem Solving

Commercial project management systems focus on preproject planning and after-the-fact documentation, but not on the dynamic problem solving required in day-to-day project management. Yet the need for risk-oriented management is clear. To understand and control project risks, managers must be able to identify problems as they occur, immediately assess their downstream impacts, and plan a course of action. The Advanced Risk Management System (ARMS) is a prototype system built to address the issues of identifying, analyzing, prioritizing, monitoring, and controlling project risk. ARMS uses expert systems, data base management, and hypermedia technologies to capture and classify project schedule problems, to determine their semantic impacts to future activities, and to alert appropriate project personnel in advance of problem occurrence.     

Estimating and comparing learning curves in three Asian economies

This paper consists of two parts. In the first, a method is suggested to isolate the effects of scale economies on learning phenomena by integrating the conventionally specified learning curve with the production function in neoclassical economics. The problem of establishing the variable for measuring experience is dealt with in the estimation procedure. Using this method we estimated the learning curves of 20 industries in the manufacturing sector in Singapore using data taken from 1961 to 1991. More modern industries like electronics, precision instruments and pharmaceutics have steeper learning curves than older industries. Among traditional industries, the food and beverage industry has a greater learning potential than others. In the second part of the paper, the learning curves for 11 common industries in South Korea, Japan and Singapore were estimated and compared. The Japanese industries are found to have steeper learning curves compared to those in Singapore and South Korea.The authors are from the Department of Business Policy, Faculty of Business Administration, National University of Singapore.

Community in a recreational setting

Abstract

The loss of community and of traditional communal ties characteristic of modern industrial society has caused many people to search for alternative sources of social identification and solidarity. Recreational sites may afford some people opportunities for constructing communities on the basis of common interests. As part of an ongoing investigation, data have been gathered over several years to discover whether elements of community can be found in a marina's social system; evidence is being sought through examination of patterns of social interaction, the system of social ranking, and ties of affection that characterize the marina's social network. Data reveal a social organization at the marina comprising subgroups with complex interaction patterns, affective ties, and communal solidarity. It appears, therefore, that at this recreational site the structure and dynamics of an alternative form of community have been constructed by boaters.     

Victimisation and agency: the social construction of union women’s leadership

This article interrogates the notion that women union leaders lead differently. Despite significant variation in the union movements in Australia, Canada, Sweden, the UK and the USA, similar discourses on women’s union leadership emerge in all five countries. Based on a materialist social construction approach which supports a recognition of difference without reference to essentialist ideas about women’s nature, this article seeks to identify what may be common across these countries to explain this phenomenon. The article argues that the fact that women face discrimination in unions, on the one hand, and organise as a constituency and have access to women‐only education, on the other, supports the development of transformational leadership among women unionists, even across diverse contexts and cultures. Unpacking union women’s leadership practices in this way reveals a dialectic of victimisation and agency.     

U.S. Equity Investment in Emerging Stock Markets

This article examines U.S. equity flows to emerging stock marketsfrom 1978 to 1991 and draws three main conclusions. First, despitethe recent increase in U.S. equity investment in emerging stockmarkets, the U.S. portfolio remains strongly biased toward domesticequities. Second, of the fraction of the U.S. portfolio thatis allocated to foreign equity investment, the share investedin emerging stock markets is roughly proportional to the shareof the emerging stock markets in the global market capitalizationvalue. Third, the volatility of U.S. transactions in emerging-marketequities is higher than in other foreign equities. The normalizedvolatility of U.S. transactions appears to be falling over time,however, and we find no relation between the volume of U.S.transactions in foreign equity and local turnover rates or volatilityof stock returns.     

Nothing Tastes as Local: Jordanians’ Perceptions of Buying Domestic Olive Oil

To date, little is known about how consumers perceive local and foreign olive oil. This study was conducted with the intention of exploring key trends in Jordanian consumers’ perceptions toward local olive oil and to examine whether they are ethnocentric toward purchasing their local olive oil in the era of the Arab Spring. The research design is a combination of quantitative with a qualitative technique to support and expand on the research findings. Data were collected from a total number of 196 Jordanians who live in Amman city. The results revealed that Jordanians are loyal to their country’s olive oil; they expressed strong ethnocentric tendencies toward purchasing it, and their purchasing tendencies are influenced by nationalism. Jordanians ranked their local olive oil as the best worldwide. This article provides original insights into the development and marketing strategies for local and global olive oil producers in the Jordan market and other Arab country markets.     

Tunneling and propping: A justification for pyramidal ownership

This paper links existence of the pyramidal ownership structure to tunneling and propping. Tunneling refers to a transfer of resources from a lower-level firm to a higher-level firm in the pyramidal chain, whereas propping concerns a transfer in the opposite direction intended to bail out the receiving firm from bankruptcy. We show that tunneling alone cannot justify the pyramidal structure unless outside investors are myopic, since rational outside investors anticipate tunneling and adjust their willingness-to-pay for the firm’s shares accordingly. With propping, however, they may be willing to be expropriated in exchange for implicit insurance against bankruptcy.     

Seatbelt use among drivers in an urban city in Nigeria: an observational study

Studies from parts of Nigeria reported low compliance with seatbelt. This study sought to establish driver seatbelt use in Enugu, Nigeria by gender, vehicle type/use and time of day. Observations were done day and night at randomly selected locations. Data were analysed with SPSS version 15. Differences in response were checked with chi-square for trend. Confidence interval was 95% and P value < 0.05 was regarded as significant. Average compliance was 37.6% for the 510 males (85%) and 90 females (15%) observed. It was 74.8% in the day and 0.3% at night. Among males, 218 (42.7%) wore seatbelt while 9 (10%) females did. For commercial drivers 159 (65.2%) complied while 68 (19.1%) private drivers did. Truck drivers had 100% compliance while sports utility vehicle drivers had the lowest (18.8%). There is poor seatbelt compliance in Enugu, Nigeria and need for educational campaigns and stricter enforcement.     

Neither an Authentic Product nor a Counterfeit: The Growing Popularity of Shanzhai Products in Global Markets

Counterfeits have been a longstanding concern to global brand manufactures. However, recently, a new product category that partly imitates and partly innovates under the term shanzhai has entered into market. Shanzhai products mimic original leading brands through visual or functional similarities and may also provide additional features. Given this new copycat phenomenon, our study for the first time conceptually distinguishes shanzhai products from counterfeits, theoretically compares the values of consumers choosing shanzhai products versus counterfeits, and empirically tests such differences in one integrative model. Specifically, shanzhai buyers value product functional benefits more than counterfeit buyers, while counterfeit buyers value status consumption, yet experience less self‐clarity than shanzhai buyers. Our findings offer important implications for imitative innovation literature as well as for practitioners.
