Requirements for using simulation to design and assess wireless ATM handover solutions

1999

Wireless ATM (WATM) has been widely considered as a solution for broadband wireless services. Handover is one of the most important mobility support functions in the WATM network. Many handover solutions have been proposed, analysed, and benchmarked. Simulations have been broadly used to assess these solutions. However, there are many dilemmas in how simulation has been applied as a research methodology: heterogeneous simulation systems used, lack of comparison with other related work, biased conclusions, and unavailability of simulation models and systems to researchers. The WATM research community lacks a standard and commonly acceptable methodology for applying simulation. To address thi…

Understanding Interaction Search Behavior in Professional Social Networks

2011

We present an empirical study of social interaction in a professional social network. As the point of departure, we take previous research into distributed work and information foraging theory to explore interaction search behavior of individuals active in professional networks, examining how social factors govern their behavior. For this exploration, we focused on the process through which relevant collaborators are chosen to execute shared work tasks in the area of logistics, and identified six characteristics of the explored processes. We recognized the “survival of the social” as a cornerstone for efficient and long-term professional networks and outlined design implications arising fro…

A note on normalization schemes: The case of generalized forecast error variance decompositions

2016

The aim of this paper is to propose new normalization schemes for the values obtained from the generalized forecast error variance decomposition, in order to obtain more reliable net spillover measures. We provide a review of various matrix normalization schemes used in different application domains. The intention is to contribute to the financial econometrics literature aimed at building a bridge between different approaches able to detect spillover effects, such as spatial regressions and network analyses. Considering DGPs characterized by different degrees of correlation and persistence, we show that the popular row normalization scheme proposed by Diebold and Yilmaz (2012), as well as t…

Fullerene-Polymers: Synthesis, Properties and Applications

2009

Written by an outstanding team of experts in the interdisciplinary areas of research, this book is based on a new classification of the different types of fullerene polymers according to their chemical structures. It covers all aspects, from different classes, to their synthesis and applications in material science. Of great interest to polymer and synthetic chemists, but also for material scientists and industrial chemists.

Making Sense of Business Ethics - About Not Walking the Talk

2006

By using a sensemaking perspective, this article argues that it is not relevant to fully expect firms to walk their talk in ethical matters. Accuracy between words and deeds is utopia in a post-modern world, with chaos and complexity. Integrating diverse ways of doing ethical business across global regions rather creates legitimacy, trust and a good image among firms in business networks. So what is the role of the ethics code? The article gives examples from a case study on Stora Enso, where the ethics code has a certain strategic meaning, but where the CEO also states that the firm has to do what it says, and say what it does. In short, the article discusses a new paradigm which influence…

Impact of Status and Meme Content on the Spread of Memes in Virtual Communities

2015

We examined the influence of meme consistency (vs. inconsistency) and intragroup status on the spread of memes in virtual communities. Prior research suggests that information consistent with the theme of the group is remembered better and that ideas threatening to the group identity are rejected. In addition, previous research shows that low-status group members mimic high-status members and communicate with them to seek information and approval. We analyzed social interactions among members of four online forums from January 1, 2010, to February 21, 2014. Contrary to our prediction, our results show that memes initiated by low-status members spread faster than memes started by high- or mo…

Individuals’ Use of E-Mail Communication Genres in Open Source Software Community Building

2011

The advent of the participative Internet (Web 2.0) sheds a new light on traditional knowledge about communication practices. The role of information and communication technologies seems to be very central in managerial literature, while the human side of the issue is less considered. This paper argues that individuals establish communication genres as semantic templates for accomplishing their communicative projects. Communication genres are codes of default behavioral expectations resulting from recurrent communication actions over the time. By using semantic network analytical techniques, our argument is explored in a particular empirical setting, that is, a virtual community of open sour…
