This article promotes sentiment analysis as an alternative research technique for collecting and analyzing textual data on the internet. Sentiment analysis is a data mining technique that systematically evaluates textual content using machine learning techniques. As a research method in marketing, sentiment analysis presents an efficient and effective evaluation of consumer opinions in real tim...

This study reports results from an empirical study of 109 software maintenance tasks in the software maintenance department of a Norwegian company. Findings were, amongst others, that: • While there was a reduction in the frequency of major unexpected problems from tasks solved by very inexperienced to medium experienced maintainers, additional years of experience did not lead to further reduct...

The purpose of this review is to give an insight into the considerable potential of lecithin based nanocarriers. The lecithin microemulsion and closely related microemulsion based systems are currently of interest to pharmaceutical researchers. Conventional systems for topical delivery of drugs meet many hindrances like reduced permeation and entrapment efficiency. Lecithin nanocarriers with th...

This paper suggests multi-agent systems (MASs) for implementing game artificial intelligence (AI) for video games. One of main hindrances against using MASs technology in video games has been the real-time constraints for frame rendering. In order to deal with the real-time constraints, we introduce an adaptation-oriented approach for maintaining frame rate in acceptable ranges. The adaptation ...

High-spin states in the 164 68Er96 region were studied using Be + Gd reactions. Pulsed beam conditions were exploited for enhanced sensitivity to delayed γ-ray transitions. New isomers were identified in Dy, Ho, Er and Er. The Er isomer is interpreted to decay by E1 transitions to the ground-state-band (g.s.b.) with a reduced hindrance of fν=33. A plot of fν values for all ∆K=7, E1 transitions ...

Silicon epitaxy on hydrogen-terminated Si(001) surfaces has been studied using molecular dynamics simulations. Epitaxy on the dihydride-terminated Si(001 )-( 1 × 1) surface is inhibited for Si atoms at thermal energies due to strain hindrances created by hydrogen. At greater incident Si atom energies (2-10 eV), epitaxy proceeds primarily through "subplantation", i.e. subsurface implantation of ...

Security of wireless sensor network (WSN) remained an open research area throughout the current decade. New research and developments seems protecting sensor networks from various security threats but at the same time raise many questions, confusions and conflicts regarding their own viability. Such viability issues become major hindrances in security assessment of WSNs against posed security t...

The ethnic/racial demographic of the United States is in the midst of significant change and physicians must be adept at recognizing and effectively treating dermatologic disease states in patients with skin of color. Inherent in effectively treating these cutaneous diseases is sufficiently understanding the patient’s viewpoint about his/her disease, as well as hindrances to treatment, complian...

Corpus-based learning methods for natural language processing now provide a consistent way to achieve systems with good performance. A number of statistical learning models have been proposed and are used in most of the tasks which used to be handled by rule-based systems. When the learning systems come to such a level as competitive as manually constructed systems, both large scale training co...

Punishing Free-Riders: How Group Size Affects Mutual Monitoring and the Provision of Public Goods Because costly punishment is not credible, subgame perfection suggests that punishment will not deter free riding, regardless of the size or structure of groups. However, experiments show that people will punish free riders, even at considerable cost. To examine the implications of agents who punis...
