The present historical moment may seem a particularly inopportune time to review Bowling Alone, Robert Putnam's latest exploration of civic decline in America. After all, the outpouring of volunteerism, solidarity, patriotism, and self-sacrifice displayed by Americans in the wake of the September 11 terrorist attacks appears to fly in the face of Putnam's central argument: that \"social capital\" -defined as \"social networks and the norms of reciprocity and trustworthiness that arise from them\" (p. 19)'has declined to dangerously low levels in America over the last three decades. However, Putnam is not fazed in the least by the recent effusion of solidarity. Quite the contrary, he sees in it the potential to \"reverse what has been a 30to 40-year steady decline in most measures of connectedness or community.\"' As an example of how the current \"war on terrorism\" could generate a durable civic renewal, Putnam points to the burst in civic practices that occurred during and after World War II, which he says \"permanently marked\" the generation that lived through it and had a \"terrific effect on American public life over the last half-century.\" 3 If Americans can follow this example and channel their current civic

The growing commercial interest in indoor location-based services (ILBS) has spurred recent development of many indoor positioning techniques. Due to the absence of global positioning system (GPS) signal, many other signals have been proposed for indoor usage. Among them, Wi-Fi (802.11) emerges as a promising one due to the pervasive deployment of wireless LANs (WLANs). In particular, Wi-Fi fingerprinting has been attracting much attention recently because it does not require line-of-sight measurement of access points (APs) and achieves high applicability in complex indoor environment. This survey overviews recent advances on two major areas of Wi-Fi fingerprint localization: advanced localization techniques and efficient system deployment. Regarding advanced techniques to localize users, we present how to make use of temporal or spatial signal patterns, user collaboration, and motion sensors. Regarding efficient system deployment, we discuss recent advances on reducing offline labor-intensive survey, adapting to fingerprint changes, calibrating heterogeneous devices for signal collection, and achieving energy efficiency for smartphones. We study and compare the approaches through our deployment experiences, and discuss some future directions.

Wi-Fi Fingerprint-Based Indoor Positioning: Recent Advances and Comparisons

In this landmark book, Scott Page redefines the way we understand ourselves in relation to one another. The Difference is about how we think in groups--and how our collective wisdom exceeds the sum of its parts. Why can teams of people find better solutions than brilliant individuals working alone? And why are the best group decisions and predictions those that draw upon the very qualities that make each of us unique? The answers lie in diversity--not what we look like outside, but what we look like within, our distinct tools and abilities. The Difference reveals that progress and innovation may depend less on lone thinkers with enormous IQs than on diverse people working together and capitalizing on their individuality. Page shows how groups that display a range of perspectives outperform groups of like-minded experts. Diversity yields superior outcomes, and Page proves it using his own cutting-edge research. Moving beyond the politics that cloud standard debates about diversity, he explains why difference beats out homogeneity, whether you're talking about citizens in a democracy or scientists in the laboratory. He examines practical ways to apply diversity's logic to a host of problems, and along the way offers fascinating and surprising examples, from the redesign of the Chicago "El" to the truth about where we store our ketchup. Page changes the way we understand diversity--how to harness its untapped potential, how to understand and avoid its traps, and how we can leverage our differences for the benefit of all.

Prologue to The Difference: How the Power of Diversity Creates Better Groups, Firms, Schools, and Societies

Purpose – This research extends Mehrabian and Russell's Stimulus‐Organism‐Response model to include both external (i.e. reputation) and internal source of information (i.e. website quality) as stimuli which affect consumers' response systems. The purpose of this paper is to test a more comprehensive model consisting of reputation and website quality (stimuli), cognition and emotion (organism) and purchase intention (response).Design/methodology/approach – In total, 219 usable questionnaires were obtained at a large Midwestern university through online survey. Structural equation modeling (SEM) was employed for data analyses.Findings – Reputation had a significant positive effect on consumers' emotion and significant negative effect on perceived risk. All four website quality dimensions had significant negative effects on perceived risk and significant positive effects on emotion, except for customer service. Perceived risk had a significant negative effect on consumers' emotion, and both perceived risk an...

Effects of reputation and website quality on online consumers' emotion, perceived risk and purchase intention: Based on the stimulus‐organism‐response model

Consumer adaptation and infusion of wearable devices for healthcare

A WLAN (Wireless Local Area Network) based Extended Kalman Filter (EKF) method for indoor positioning is introduced in this paper. WLAN based indoor positioning is more economical than other methods because it does not require any special equipment dedicated to positioning. The most popular technique used for indoor positioning is the fingerprinting method, but the EKF method is easier to deploy because, unlike fingerprinting, it does not require a time consuming off-line phase. This paper also provides experimental comparisons of our EKF method with other indoor positioning methods.

Extended Kalman Filter for wireless LAN based indoor positioning

Location Based Service (LBS) cannot be realized unless the location of the user is available. For indoor LBS, indoor positioning must be utilized and many researchers have been working on indoor positioning and tracking. For example, Extended Kalman filter (EKF) was exploited in Bluetooth based indoor positioning. Nowadays, WLAN (Wireless Local Area Network) is available virtually everywhere. Thus, WLAN based indoor positioning and tracking is more economical than Bluetooth based ones. This paper proposes a new WLAN based EKF indoor tracking method by extending existing Bluetooth based EKF positioning method. After analyzing the experimental results of it, we modified it to use K-NN method in the measurement stage of it. Then we propose to further improve the accuracy of indoor tracking by adjusting the parameter values referring to the map information. Experimental results comparing our method with other previous methods are discussed.

New information technology is a core factor enabling innovation in knowledge management (KM). The purpose of this study is to analyze the limitations of current KM systems and to propose an approach for applying the Semantic Web to KM. We analyzed the factors that affect KM system user dissatisfaction through a survey. We found that inconvenience, search and integration were statistically significant limitation factors for system quality. On the other hand, incongruence and untrustworthiness of knowledge were significant limitation factors for knowledge quality. Finally, we suggest methods for applying the Semantic Web to KM as an alternative overcoming the technical limitations of current KM systems.

Adoption of the Semantic Web for overcoming technical limitations of knowledge management systems

It is important to analyze the relationship between customer values and business value in order to provide a guideline of successful e-business. The purpose of this paper is to answer the following questions. First, what are key components of customer value in e-business? Second, what difference exists in the expectation level and current level of customer value in e-business? Finally, what influences the relationship between customer value and business value? Data collected from 615 respondents who made purchases through Internet shopping malls were used to test a research model. Three managerial implications were derived from the analysis and further studies were suggested.
