    This report identifies impersonal efficiency as a driver of market automation during the past four decades, and speculates about the future problems it might pose. The ideology of impersonal efficiency is rooted in a mistrust of financial intermediaries such as floor brokers and specialists. Impersonal efficiency has guided the development of market automation towards transparency and impersonality, at the expense of human trading floors. The result has been an erosion of the informal norms and human judgment that characterize less anonymous markets. We call impersonal efficiency an ideology because we do not think that impersonal markets are always superior to markets built on social ties. This report traces the historical origins of this ideology, considers the problems it has already created in the recent Flash Crash of 2010, and asks what potential risks it might pose in the future

    In this research, we propose an architectural solution to implement the voice over IP (VoIP) service in campus environment network. Voice over IP (VoIP) technology has become a discussion issue for this time being. Today, the deployment of this technology on an organization truly can give a great financial benefit over traditional telephony. Therefore, this study is to analyze the VoIP Codec selection and investigate the Mean Opinion Score (MOS) performance areas evolved with the quality of service delivered by soft phone and IP phone. This study focuses on quality of voice prediction such as i) accuracy of MOS between automated system and human perception and ii) different types of codec performance measurement via human perception using MOS technique. In this study, network management system (NMS) is used to monitor and capture the performance of VoIP in campus environment. In addition, the most apparent of implementing soft phone and IP phone in campus environment is to define the best codec selection that can be used in operational environment. Based on the finding result, the MOS measurement through automated and manual system is able to predict and evaluate VoIP performance. In addition, based on manual MOS measurement, VoIP conversations over LAN contribute more reliability and availability performance compare to WAN.Comment: 14 pages, exposed on 5th International Conference "Actualities and Perspectives on Hardware and Software" - APHS2009, Timisoara, Romani

    To inform action impact investors could take to measure impact in a coordinated manner, The Rockefeller Foundation commissioned the study of impact assessment approaches presented here.It is natural to hope to find a single, turnkey solution that can address all measurement needs. In this study we conducted a survey of impact investors and complemented it with seven years of experience in the field of impact investing to discover what these investors want from impact measurement, and conducted in-depth interviews with over twenty entities that have developed and implemented approaches to measuring impact. Our survey of existing approaches was thorough but surely is not comprehensive; however the approaches are a good representation of the current state of play. What we found is that there is not one single measurement answer. Instead the answer depends on what solution is most appropriate for a particular investor's "impact profile" defined as the investor's level of risk tolerance and desired financial return, the particular sector in which the investor operates, geography, and credibility level of information about impact that the investor requires
