Linking consumer trust perception in constructing an e-commerce trust model

Trust issues is still considered as a main obstacle in the implementation of eCommerce Due to the increasing numbers of cyber crimes committed today, consumers are faced with doubt to engage in online shopping. As a safety precaution, consumers will take certain measures to protect their information by evaluating and assessing these websites trustworthiness before an actual purchase occurs. This paper describes a model that examines the elements related to online consumer behavior and to investigate this behavior towards building and increasing trust. The applicability of the model was tested in attempt to view consumers' acceptance towards the model and its component. The fmdings indicate the respondents are aware of the trust issue surrounding e-Commerce implementation as they accept and agreed with the model and its components

The Dynamic Interplay of Inequality and Trust - An Experimental Study

We study the interplay of inequality and trust in a dynamic game, where trust increases efficiency and thus allows higher growth of the experimental economy in the future. We find that trust is initially high in a treatment starting with equal endowments, but decreases over time. In a treatment with unequal endowments, trust is initially lower yet remains relatively stable. The difference seems partly due to the fact that equal start positions increase subjects’ inclination to condition their trust decisions on wealth comparisons, whereas conditional trust is much less prevalent with unequal initial endowments. As a result, with respect to efficiency, the initially more unequal economy fares worse in the short run but better in the long run, and the disparity of wealth distributions across economies mitigates over time.inequality, trust, growth, laboratory experiments

A data-driven game theoretic strategy for developers in software crowdsourcing: a case study

Crowdsourcing has the advantages of being cost-effective and saving time, which is a typical embodiment of collective wisdom and community workers’ collaborative development. However, this development paradigm of software crowdsourcing has not been used widely. A very important reason is that requesters have limited knowledge about crowd workers’ professional skills and qualities. Another reason is that the crowd workers in the competition cannot get the appropriate reward, which affects their motivation. To solve this problem, this paper proposes a method of maximizing reward based on the crowdsourcing ability of workers, they can choose tasks according to their own abilities to obtain appropriate bonuses. Our method includes two steps: Firstly, it puts forward a method to evaluate the crowd workers’ ability, then it analyzes the intensity of competition for tasks at Topcoder.com—an open community crowdsourcing platform—on the basis of the workers’ crowdsourcing ability; secondly, it follows dynamic programming ideas and builds game models under complete information in different cases, offering a strategy of reward maximization for workers by solving a mixed-strategy Nash equilibrium. This paper employs crowdsourcing data from Topcoder.com to carry out experiments. The experimental results show that the distribution of workers’ crowdsourcing ability is uneven, and to some extent it can show the activity degree of crowdsourcing tasks. Meanwhile, according to the strategy of reward maximization, a crowd worker can get the theoretically maximum reward

The case for preserving our knowledge and data in physics experiments

This proceeding covers tools and technologies at our disposal for scientific data preservation and shows that this extends the scientific reach of our experiments. It is cost-efficient to warehouse data from completed experiments on the tape archives of our national and international laboratories. These subject-specific data stores also offer the technologies to capture and archive knowledge about experiments in the form of technical notes, electronic logs, websites, etc. Furthermore, it is possible to archive our source code and computing environments. The paper illustrates these challenges with experience from preserving the LEP data for the long term.Comment: 5 pages, 1 figur

Security in Pervasive Computing: Current Status and Open Issues

Million of wireless device users are ever on the move, becoming more dependent on their PDAs, smart phones, and other handheld devices. With the advancement of pervasive computing, new and unique capabilities are available to aid mobile societies. The wireless nature of these devices has fostered a new era of mobility. Thousands of pervasive devices are able to arbitrarily join and leave a network, creating a nomadic environment known as a pervasive ad hoc network. However, mobile devices have vulnerabilities, and some are proving to be challenging. Security in pervasive computing is the most critical challenge. Security is needed to ensure exact and accurate confidentiality, integrity, authentication, and access control, to name a few. Security for mobile devices, though still in its infancy, has drawn the attention of various researchers. As pervasive devices become incorporated in our day-to-day lives, security will increasingly becoming a common concern for all users - - though for most it will be an afterthought, like many other computing functions. The usability and expansion of pervasive computing applications depends greatly on the security and reliability provided by the applications. At this critical juncture, security research is growing. This paper examines the recent trends and forward thinking investigation in several fields of security, along with a brief history of previous accomplishments in the corresponding areas. Some open issues have been discussed for further investigation

Treading the lines between self-interest, cultural relativism and universal principles: ethics in the global marketplace

Purpose: This paper introduces this special issue of Management Decision by exploring the themes of the issue and the contribution of each of the articles in the collection. Approach: The paper reviews notions of ethics, justice and responsibility. It then uses the framework developed through this review as the basis for an appreciation of the articles that constitute the issue. Value: This article provides an introduction to, and suggests an overarching framework for, this special issue on questions we ask about ethics in a global marketplace. It is also an important reminder to managers and employees who constitute the entities to which “responsibility” is generally attached, that responsibility, ultimately, is irreducible beyond the individual, who cannot simply “follow orders”
