Adolescent self-mutilative behavior (SMB) is a pervasive and dangerous problem, yet factors influencing the performance of SMB are not well understood. The authors examined the contextual features and behavioral functions of SMB in a sample of 89 adolescent psychiatric inpatients. SMB typically was performed impulsively, in the absence of physical pain, and without the use of alcohol or drugs. ...

It is clearly in the interest of network administrators to detect hosts within their networks that are infiltrated by stealthy malware. Infected hosts (also called bots) can exfiltrate sensitive data to adversaries, or lie in wait for commands from a bot-master to forward spam, launch denial-of-service attacks, or host phishing sites, for example. Unfortunately, it is difficult to detect such h...

OBJECTIVE To identify clinical features in behavioral-variant frontotemporal dementia that may help predict tau-positive pathology. METHODS Clinical and historical features of patients with pathologically confirmed tau-positive and tau-negative frontotemporal lobar degeneration from 1970 to 2006 were retrospectively reviewed in a blinded fashion. The initial clinical features of those patient...

Both language and music consist of discrete elements organized in embedded hierarchical structures. Schön and François nicely expose in this review that musical expertise facilitates learning of both linguistic and musical structures. At the behavioral level, the musicians did not outperform the nonmusicians. However, ERP analyses showed that acquisition of boundary perception (segmentation) be...

Early, James P. Ph.D., Purdue University, August, 2005. Behavioral Feature Extraction for Network Anomaly Detection. Major Professors: Carla E. Brodley and Eugene H. Spafford. This dissertation presents an analysis of the features of network traffic commonly used in network-based anomaly detection systems. It is an examination designed to identify how the selection of a particular protocol attr...

In dynamical systems, local interactions between dynamical units generate correlations which are stored and transmitted throughout the system, generating the macroscopic behavior. However a framework to quantify and study this at the microscopic scale is missing. Here we propose an ‘information processing’ framework based on Shannon mutual information quantities between the initial and future s...

The design of a website interface plays an important role in online purchasing, and customers are more likely to visit and buy from betterdesigned websites. However, previous studies have not provided consistent information about the features a website should provide. Based on Hausman and Siekpe’s (2009) comprehensive model, this study aims to empirically verify whether the model can be applied...

The recent research direction toward multimodal semantic representation would be further advanced, if we could have a machinery to collect adequate images from the Web, given a target concept. With this motivation, this paper particularly investigates into the Webimageabilities of the behavioral features (e.g. “beaver builds dams”) of a basic-level concept (beaver). The term Web-imageability de...

Object Recognition is the domain of computer vision that deals with the classification of objects in two or three dimensions as instances of predetermined object classes, and is useful for image analysis and understanding. One of the most powerful properties used for recognition of objects is the shape of the object. Other features traditionally used include color, texture, moments and other at...
