Trust in Electronic Commerce: A New Model for Building Online Trust in B2C

The rapid growth in the electronic commerce over the internet has fuelled predictions and speculations about what makes a business to consumer (B2C) web site effective. Increasing use of the World Wide Web as a B2C commercial tool raises interest in understanding the key issues in building relationships with customers on the internet. Trust is believed to be the key to these relationships. In this paper, an overall model has presented for building online trust in this context. This model outlines some of the key factors that are related in this area and suggests a framework based on these factors. With respect to the position and importance of the trust in online commerce, this model helps businesses in order to capture, sustain and construct long-term relationships with their consumers.               Keywords: E-Trust, Reverse engineering, Business-consumer web sites, online shopping, Web desig

Ethics in Management Accounting: Moving toward Ethical Motivation

In today’s business environment, the role of accountants is significant. Managers and other decision makers base their decisions mainly on information that accountants provide. Since accuracy of decisions depends on the reliability of accounting information, the ethical dimension of the profession has gained considerable attention recently. In fact, management accountants are required to make ethical choices in many settings. Base on the Rest’s model that is an ethical decision making’s model, 4 inner psychological processes (ethical sensitivity, judgment, motivation and character) together give rise to outwardly observable behavior. Professional organizations like IMA[1] support management accountants in recognizing and solving specific situations or dilemmas which management accountants may encounter by preparing codes of ethics and teaching them. But, ethics education solely does not lead to a success in the emergence of ethical behavior. An individual’s willingness and motivation has been recognized as a crucial factor in engaging in ethical decision making. With regard to the importance and position of motivation in ethical decisions it requires to special attention, nonetheless most of the studies have been concentrated on two first dimensions, ethical sensitivity and judgment. Therefore, this paper is intended to recognize some of important and influential factors on ethical motivation of management accountants and to explain the relations between these factors and also relationship between these factors with the motivation in rest’ model. It’s noticeable that organizations have a critical and basic role in ethical motivation of their own employees. finally, in order to ethical motivation of management accountants, guidelines will be presented that implementing and performing these recommendations by organizations can result in motivation and consequently ethical intention of management accountants.

Neuroinspired unsupervised learning and pruning with subquantum CBRAM arrays.

Resistive RAM crossbar arrays offer an attractive solution to minimize off-chip data transfer and parallelize on-chip computations for neural networks. Here, we report a hardware/software co-design approach based on low energy subquantum conductive bridging RAM (CBRAM®) devices and a network pruning technique to reduce network level energy consumption. First, we demonstrate low energy subquantum CBRAM devices exhibiting gradual switching characteristics important for implementing weight updates in hardware during unsupervised learning. Then we develop a network pruning algorithm that can be employed during training, different from previous network pruning approaches applied for inference only. Using a 512 kbit subquantum CBRAM array, we experimentally demonstrate high recognition accuracy on the MNIST dataset for digital implementation of unsupervised learning. Our hardware/software co-design approach can pave the way towards resistive memory based neuro-inspired systems that can autonomously learn and process information in power-limited settings

New Exact Solutions of some Nonlinear Partial Differential Equations by the First Integral Method

The first integral method is an efficient method for obtaining exact solutions of nonlinear partial differential equations. The efficiency of the method is demonstrated by applying it for two selected equations. This method can be applied to nonintegrable equations as well as to integrable ones

An electro-thermal computational study of conducting channels in dielectric thin films using self-consistent phase-field methodology: A view toward the physical origins of resistive switching

A large number of experimental studies suggest two-terminal resistive switching devices made of a dielectric thin film sandwiched by a pair of electrodes exhibit reversible multi-state switching behaviors; however coherent understanding of physical and chemical origins of their electrical properties needs to be further pursued to improve and customize the performance. In this paper, phase-field methodology is used to study the formation and annihilation of conductive channels resulting in reversible resistive switching behaviors that can generally occur in any dielectric thin films. Our focus is on the dynamical evolution of domains made of electrical charges under the influence of spatially varying electric field and temperature resulting in distinctive changes in electrical conductance.Comment: 6 pages, 5 figure

On the convergence of two-dimensional fuzzy Volterra-Fredholm integral equations by using Picard method

In this paper we prove convergence of the method of successive approximations used to approximate the solution of nonlinear two-dimensional Volterra-Fredholm integral equations and define the notion of numerical stability of the algorithm with respect to the choice of the first iteration. Also we present an iterative procedure to solve such equations. Finally, the method is illustrated by solving some examples

This method is straightforward and concise, and it may also be applied to other nonlinear evolution equations
