...Computer Game Addiction - Symptoms, Treatment, & FAQs By Dr. Brent Conrad Clinical Psychologist for TechAddiction What is computer game addiction? Computer game addiction generally refers to an excessive, unhealthy amount of playing computer games. Rather than engaging in the real world, an addicted user devotes the majority of his or her time to gaming. The addicted gamer often isolates him/herself from others, ignores more important responsibilities, and is often obsessed with obtaining higher status / rankings / achievements in his/her favorite computer game. Is computer game addiction a diagnosable disorder? According to the DSM-IV (the current manual for classifying emotional, psychological, and mental disorders), no. Although there have been calls from some mental health professionals (and parents) to recognize computer game addiction as a "real" disorder, it has not been granted official diagnostic status. As more research on the effects of excessive gaming is conducted, many believe that it is only a matter of time before computer game addiction is classified as a compulsive behavior similar to gambling addiction. What are the symptoms of computer game addiction? Because there is no official diagnosis of computer game addiction, there is obviously no universally agreed upon list of symptoms. Psychologists and other mental health professionals initially adapted the diagnostic criteria for gambling addiction and used this as a rough assessment tool...

This is reflected by the tremendous activity in the public and private sector to better understand the myriad of cyber challenges, identifying existing gaps and needs and closing these gaps as quickly and firmly as possible through government policy initiatives, public/private partnerships, and legal/insurance penalty and incentive regimes. However when we examine the academic literature, the research and publications in this area are rather sparse. Consequently, this special issue on Security in the Cyber Supply Chain is intended to act as a resource to practitioners and as a call to research. & 2014 Published by Elsevier Ltd. Introduction In general, the cyber supply chain provides tremendous advances in efficiency and effectiveness. The economy gains through transactions being more efficient through the low cost rapid transmission of information related to supply chain management. Not only does this rapid transmission reduce cost, but it also provides value through increased effectiveness allowing for services and decisions that were not possible...

...Univ Access Inf Soc (2015) 14:81–95 DOI 10.1007/s10209-014-0348-1 LONG PAPER Technology acceptance model: a literature review from 1986 to 2013 ´ ´ Nikola Marangunic • Andrina Granic Published online: 16 February 2014 Ó Springer-Verlag Berlin Heidelberg 2014 Abstract With the ever-increasing development of technology and its integration into users’ private and professional life, a decision regarding its acceptance or rejection still remains an open question. A respectable amount of work dealing with the technology acceptance model (TAM), from its first appearance more than a quarter of a century ago, clearly indicates a popularity of the model in the field of technology acceptance. Originated in the psychological theory of reasoned action and theory of planned behavior, TAM has evolved to become a key model in understanding predictors of human behavior toward potential acceptance or rejection of the technology. The main aim of the paper is to provide an up-to-date, wellresearched resource of past and current references to TAMrelated literature and to identify possible directions for future TAM research. The paper presents a comprehensive concept-centric literature review of the TAM, from 1986 onwards. According to a designed methodology, 85 scientific publications have been selected and classified according to their aim and content into three categories such as (i) TAM literature reviews, (ii) development and extension of TAM, and (iii) modification...

...482 IEEE TRANSACTIONS ON SYSTEMS, MAN, AND CYBERNETICS—PART B: CYBERNETICS, VOL. 42, NO. 2, APRIL 2012 An Adaptive Differential Evolution Algorithm With Novel Mutation and Crossover Strategies for Global Numerical Optimization Sk. Minhazul Islam, Swagatam Das, Member, IEEE, Saurav Ghosh, Subhrajit Roy, and Ponnuthurai Nagaratnam Suganthan, Senior Member, IEEE Abstract—Differential evolution (DE) is one of the most powerful stochastic real parameter optimizers of current interest. In this paper, we propose a new mutation strategy, a fitnessinduced parent selection scheme for the binomial crossover of DE, and a simple but effective scheme of adapting two of its most important control parameters with an objective of achieving improved performance. The new mutation operator, which we call DE/current-to-gr_best/1, is a variant of the classical DE/current-to-best/1 scheme. It uses the best of a group (whose size is q% of the population size) of randomly selected solutions from current generation to perturb the parent (target) vector, unlike DE/current-to-best/1 that always picks the best vector of the entire population to perturb the target vector. In our modified framework of recombination, a biased parent selection scheme has been incorporated by letting each mutant undergo the usual binomial crossover with one of the p top-ranked individuals from the current population and not with the target vector with the same index as used in all variants of DE. A DE variant obtained...

Papageorgiou*,† Centre for Process Systems Engineering, Department of Chemical Engineering, UniVersity College London, Torrington Place, London WC1E 7JE, U.K., and Process Systems R&D, Praxair Inc., 39 Old Ridgebury Rad, Danbury, Connecticut 06810 This article considers the short-term scheduling of a single-stage batch edible-oil deodorizer that can process multiple products in several product groups. Sequence-dependent changeovers occur when switching from one product group to another. Based on the incorporation of products into product groups, mixed integer linear programming (MILP) models are proposed for two scenarios, with and without backlogs. Then, the models are successfully applied to a real-world case with 70 product orders over a 128-h planning horizon. Compared with a literature model developed for a similar problem, the proposed models exhibit significantly better performance. 1. Introduction In the past decade, a large number of optimization models and approaches have been proposed for batch scheduling and planning. A number of reviews on the planning and scheduling of batch processes have been presented in the literature.1-6 Initially, discrete-time formulation models using the state-task network7 (STN) or resource-task network8 (RTN) were used for batch scheduling problems...

...WIRELESS COMMUNICATIONS AND MOBILE COMPUTING Wirel. Commun. Mob. Comput. 2004; 4:247–249 (DOI: 10.1002/wcm.220) Guest Editorial Special Issue: Scalability Issues in Wireless Networks— Architectures, Protocols and Services By Amitabh Mishra, Guest Editor Scalability of computer-communication networks has been an important topic for quite some time. Internet community examined the services and protocols for scalability, and switching and routing researchers looked at the scalability of the switches and routers. Service providers studied the application architectures of the services for the scalable performance that they need to provide to subscribers and, the maintenance folks paid attention to scalability of service provisioning algorithms, protocols and software. Similarly, the wireless networking community has also started to look at the scalability issues that are relevant to wireless cellular, wireless local, as well as wireless personal area networks besides the emerging area of infrastructure-less networks such as ad-hoc and sensor networks. Surprisingly there is significant scope for research in the wireless scalability area as it relates to the ad hoc and sensor networks and this is one of the reasons why this topic was chosen for a special issue. A wireless sensor network is likely to have a large number of nodes perhaps in thousands to millions and that may create, potentially, numerous scaling problems in the networking protocols, addressing schemes, hardware architectures...

...The Role of Software Testing in the Development of Quality Software MehwishZulfiqar 13414, MS (CS) Iqra University, Islamabad. Abstract: In software testing organizations, effective knowledge management of the testing process is the key to improve the quality of software testing. Quality must be built into our products and it can never be tested in after the fact. Although QA has an important role in assuring the quality of our products, their work is entirely indirect. Their role is to influence others in the organization. Testing programs are conducted to ensure that the software application meets the specifications and service level expectations of their product. Testing improves product quality. However, there is rarely enough quality control time built into development projects, and there is an endless possibility of testing that could be executed. In this article major issues are discuss that improve the quality of software and also discuss the role of software testing in the delivery of quality software product.Simply we say that process of testing is basic, but knowing what to test for is challenging for a developer. Software testing requires well-analyzed test cases and proper execution in order to find issues in the software. It also requires efficient management of the procedures. 1. Introduction: Software systems are an increasing part of life, from business applications to consumer products. Most people have had an experience with software that did not...

...138 IEEE TRANSACTIONS ON INDUSTRIAL INFORMATICS, VOL. 8, NO. 1, FEBRUARY 2012 A Fusion Approach for Efficient Human Skin Detection Wei Ren Tan, Chee Seng Chan, Member, IEEE, Pratheepan Yogarajah, and Joan Condell Abstract—A reliable human skin detection method that is adaptable to different human skin colors and illumination conditions is essential for better human skin segmentation. Even though different human skin-color detection solutions have been successfully applied, they are prone to false skin detection and are not able to cope with the variety of human skin colors across different ethnic. Moreover, existing methods require high computational cost. In this paper, we propose a novel human skin detection approach that combines a smoothed 2-D histogram and Gaussian model, for automatic human skin detection in color image(s). In our approach, an eye detector is used to refine the skin model for a specific person. The proposed approach reduces computational costs as no training is required, and it improves the accuracy of skin detection despite wide variation in ethnicity and illumination. To the best of our knowledge, this is the first method to employ fusion strategy for this purpose. Qualitative and quantitative results on three standard public datasets and a comparison with state-of-the-art methods have shown the effectiveness and robustness of the proposed approach.

...Article pubs.acs.org/jcim Carboxyl−Peptide Plane Stacking Is Important for Stabilization of Buried E305 of Trichoderma reesei Cel5A Chunyan He, Jingfei Chen, Liaoyuan An, Yefei Wang, Zhiyu Shu, and Lishan Yao* Laboratory of Biofuels, Qingdao Institute of Bioenergy and Bioprocess Technology, Chinese Academy of Sciences, Qingdao 266061, China S * Supporting Information ABSTRACT: Hydrogen bonds or salt bridges are usually formed to stabilize the buried ionizable residues. However, such interactions do not exist for two buried residues D271 and E305 of Trichoderma reesei Cel5A, an endoglucanase. Mutating D271 to alanine or leucine improves the enzyme thermostability quantified by the temperature T50 due to the elimination of the desolvation penalty of the aspartic acid. However, the same mutations for E305 decrease the enzyme thermostability. Free energy calculations based on the molecular dynamics simulation predict the thermostability of D271A, D271L, and E305A (compared to WT) in line with the experimental observation but overestimate the thermostability of E305L. Quantum mechanical calculations suggest that the carboxyl−peptide plane stacking interactions occurring to E305 but not D271 are important for the carboxyl group stabilization. For the protonated carboxyl group, the interaction energy can be as much as about −4 kcal/mol for parallel stacking and about −7 kcal/mol for T-shaped stacking. For the deprotonated carboxyl group, the largest interaction energies for parallel...

We conduct an exhaustive survey of image thresholding methods, categorize them, express their formulas under a uniform notation, and finally carry their performance comparison. The thresholding methods are categorized according to the information they are exploiting, such as histogram shape, measurement space clustering, entropy, object attributes, spatial correlation, and local gray-level surface. 40 selected thresholding methods from various categories are compared in the context of nondestructive testing applications as well as for document images. The comparison is based on the combined performance measures. We identify the thresholding algorithms that perform uniformly better over nondestructive testing and document image applications. © 2004 SPIE and IS&T.
