Will they stay or will they go? How network properties of WebICs predict dropout rates of valuable Wikipedians

This paper contributes to our understanding of an increasingly prevalent work system, web-based internet communities (WebICs). We are particularly interested in how WebICs are governed given the fact how different they are compared to more classical forms of organization. We study the governance of a WebIC by studying the structure and dynamics of their edit network. Given the fact that the edit network is a relational structure, social network analysis is key to understanding these work systems. We demonstrate that characteristics of the edit network contribute to predicting the dropout hazard of valuable WebIC members. Since WebICs exist only thanks to the activity of their contributors, predicting drop-outs becomes crucial. The results show that reputation and controversy have different effects for different types of Wikipedians; i.e., an actor’s reputation decreases the dropout hazard of active Wikipedians, while participation on controversial pages decreases the dropout hazard of highly active Wikipedians.     

Semi-online scheduling with “end of sequence” information

We study a variant of classical scheduling, which is called scheduling with “end of sequence” information. It is known in advance that the last job has the longest processing time. Moreover, the last job is marked, and thus it is known for every new job whether it is the final job of the sequence. We explore this model on two uniformly related machines, that is, two machines with possibly different speeds. Two objectives are considered, maximizing the minimum completion time and minimizing the maximum completion time (makespan). Let s be the speed ratio between the two machines, we consider the competitive ratios which are possible to achieve for the two problems as functions of s. We present algorithms for different values of s and lower bounds on the competitive ratio. The proposed algorithms are best possible for a wide range of values of s. For the overall competitive ratio, we show tight bounds of ϕ + 1 ≈ 2.618 for the first problem, and upper and lower bounds of 1.5 and 1.46557 for the second problem. The authors would like to dedicate this paper to the memory of our colleague and friend Yong He who passed away in August 2005 after struggling with illness. D.

Trade-offs in Online Purchase Decisions:: Two Empirical Studies in Europe

The Internet offers firms a new way to market their products and services and to interact with their end-consumers. While many firms have developed websites, very little is known about the trade-offs consumers are willing to make when making online purchases. With millions of websites competing for attention, online firms need to know in what way consumers make purchase decisions online. Consumers mainly evaluate websites on the basis of choice and convenience. In this paper, we present the results of two European studies that examine what consumers actually value in an online environment. In study 1, we assess choice-related trade-offs in terms of number of product categories, variety of products within a given category and product-related information. Conjoint analysis revealed that product-related information represents an important decision-making variable. In study 2, we assess convenience-related trade-offs in terms of logistics, fulfilment and security. Conjoint analysis revealed that fulfilment is the most important variable related to online handling. Finally, our study clearly indicates that firms have to distinguish different consumer segments on the basis of their preferences. This knowledge enables online firms to use their resources more effectively.

Online strategic communication: A cross-cultural analysis of U.S. and Chinese corporate websites

This study applied a cultural divergence approach to examine online marketing interactivity and corporate public image on corporate websites. It analyzed different online strategic communication of corporate websites from two different nations—the United States and China. Results indicated that U.S. corporations were more likely to highlight online marketing interactivity and social responsibility, which integrated marketing and public relations as their online communication strategy. Chinese corporations provided more online spaces for the consumer–consumer interactions and emphasized corporation-oriented information.
