Fighting Internet auction fraud: an assessment and proposal

Online auctions constitute one of the most successful Internet business models. However, auction fraud has become far and away the largest component of all Internet fraud, posing a threat to the model's future. Traditional government organizations such as the Federal Trade Commission and the Secret Service in the US, as well as new agencies such as Internet Fraud Watch and the Internet Fraud Complaint Center, have joined auction businesses in trying to develop new mechanisms to fight this problem. We propose empowering auction communities to integrate their work with that of governments and auction institutions. Our methodology leverages news reports and auction transactions.     

Fighting identity theft: The coping perspective

The proliferation of the online business transaction has led to a large number of incidents of identity theft, which have incurred expensive costs to consumers and e-commerce industries. Fighting identity theft is important for both online business and consumers. Although the practical significance of fighting identity theft has been of great interest, empirical studies on identity theft are very limited. Drawing upon coping behavior theories, this study examines two types of coping behaviors to fight identity theft (i.e., conventional coping and technological coping). Following structural equation modeling approach, we test the model using data collected from 117 subjects through a survey. The results reveal that both conventional coping and technological coping are effective to defend against identity theft. Technological coping is determined by an individual's conventional coping, self-efficacy, perceived effectiveness of coping, and social influence. This study presents a timely empirical study on identity theft, and provides valuable insights for consumers, government agencies, and e-commerce industries.

A Variational Approach to Remove Outliers and Impulse Noise

We consider signal and image restoration using convex cost-functions composed of a non-smooth data-fidelity term and a smooth regularization term. We provide a convergent method to minimize such cost-functions. In order to restore data corrupted with outliers and impulsive noise, we focus on cost-functions composed of an ?₁ data-fidelity term and an edge-preserving regularization term. The analysis of the minimizers of these cost-functions provides a natural justification of the method. It is shown that, because of the ?₁ data-fidelity, these minimizers involve an implicit detection of outliers. Uncorrupted (regular) data entries are fitted exactly while outliers are replaced by estimates determined by the regularization term, independently of the exact value of the outliers. The resultant method is accurate and stable, as demonstrated by the experiments. A crucial advantage over alternative filtering methods is the possibility to convey adequate priors about the restored signals and images, such as the presence of edges. Our variational method furnishes a new framework for the processing of data corrupted with outliers and different kinds of impulse noise.     

Fighting Spyware and Adware in the Enterprise

Abstract

While obvious security threats like fast-spreading worms have a tendency to garner news headlines, other stealthy security risks threaten businesses every day. Increasing amounts of spyware and adware programs have the ability to facilitate the disclosure of business information and risk privacy, confidentiality, integrity, and system availability. Corporations usually accumulate a vault of information that could cause serious problems if it were shared with the wrong contacts or, even worse, taken. Spyware's evolution from simple cookies to a range of sophisticated user-tracking systems has left many businesses without the control over their proprietary data and operations.     

Fighting fire and fatigue: sleep quantity and quality during multi-day wildfire suppression

This study examined firefighters’ sleep quantity and quality throughout multi-day wildfire suppression, and assessed the impact of sleep location, shift length, shift start time and incident severity on these variables. For 4 weeks, 40 volunteer firefighters’ sleep was assessed using wrist actigraphy. Analyses revealed that the quantity of sleep obtained on fire days was restricted, and pre- and post-sleep fatigue ratings were higher, compared to non-fire days. On fire days, total sleep time was less when: (i) sleep location was in a tent or vehicle, (ii) shifts were greater than 14 h and (iii) shifts started between 05:00 and 06:00 h. This is the first empirical investigation providing objective evidence that firefighters’ sleep is restricted during wildfire suppression. Furthermore, sleep location, shift length and shift start time should be targeted when designing appropriate controls to manage fatigue-related risk and preserve firefighters’ health and safety during wildfire events.

Practitioner Summary: During multi-day wildfire suppression, firefighters’ sleep quantity was restricted, and pre- and post-sleep fatigue ratings were higher, compared to non-fire days. Furthermore, total sleep time was less when: (i) sleep occurred in a tent/vehicle, (ii) shifts were >14 h and (iii) shifts started between 05:00 and 06:00 h.     

Fighting epidemics in the information and knowledge age

Since its initial outbreak, scientists have sought to control the severe acute respiratory syndrome epidemic (SARS). So far, though, these SARS researchers have paid too little attention to the complex relationships between the epidemic, the environment, and our Information and Knowledge Age society. Fortunately, information technology can help scientists investigate the epidemic's cause and unveil its relevant principles and rules. The ideal Internet-based eco-environment management system would integrate ecological environment evaluation, data collection and publication, simulation, forecasting, and situation monitoring. It could help governments make decisions based on the current ecological and epidemiological situation, forecast developments, and evaluate the eco-environment. Professional workers in various regions could store and publish information in the system and thus make that data immediately available to people in other regions.

Parametrically Generating New Instances of Traditional Chinese Private Gardens that Replicate Selected Socio-Spatial and Aesthetic Properties

This paper describes the use of a parametric system for generating garden plans that replicate selected socio-spatial characteristics and aesthetic properties of traditional Chinese private gardens (TCPGs). To achieve this, the spatial characteristics of three historic TCPGs are first mathematically derived using connectivity analysis, a variation of a space syntax technique. The data developed through this process is then used to shape the rules of a parametric system to generate new garden plans with similar spatial connectivity values and structures. While these new plans capture some of the socio-spatial features of the TCPG, the other important characteristic of these gardens is a particular level of visual complexity. Using fractal analysis, the characteristic visual complexity of the newly generated garden plans is then compared with the historic cases, to assess the success of the system in aesthetic terms. Through this three-stage process (syntactical derivation, parametric generation and fractal analysis) the paper demonstrates a method for capturing selected spatial and aesthetic properties in a parametric system and also provides new tools for landscape design in the context of specific historical sites and approaches.
