This paper employs the lens of the resource-based view(RBV) to investigate how firms create competitive advantages through IS outsourcing arrangements. The RBV framework is used to explore how a firm adds value and reaps benefits from IS outsourcing arrangements. The primary finding is that in the process of value creation, the 'absorption' of the managerial and technical capabilities of external vendors is critical. When the client firm is able to absorb and integrate the IT capabilities of outsourcing vendors, these absorbed capabilities in turn become the source of IT competence and competitive advantages $vis-\grave{a}-vis$ the competition.

A vendor selection problem consists of two different kinds of decision making. First one is to choose the best suppliers among all possible suppliers and the next is to allocate the optimal quantities of orders among the selected vendors. In this study, an integration of the technique for order preference by similarity to ideal solution (TOPSIS) and a multi-objective mixed integer programming (MOMIP) is developed to account for all qualitative and quantitative factors which are used to evaluate and choose the best group of vendors and to decide the optimal order quantity for each vendor. A solution methodology for the vendor selection model of multiple-vendor, multiple-item with multiple decision criteria and in respect to finite vendor capacity is presented.

The internet has become an important part of the many aspects of people's daily lives such as work, study, entertainment and in form of electronic commerce, shopping. Electronic commerce is growing rapidly in Kenya. There are many successful business-to-business, business-to-customer and customer-to-customer online shopping companies in Kenya. As a consequence, competition between vendors is intense and, therefore, mitigating the negative effects of high product uncertainty is necessary requirement as it remains a biggest hindrance for success of the online shopping. The purpose of this research is to investigate how online product description, third party product assurance, customer service and website design mitigate the negative impact of high product uncertainty. A questionnaire with 28 items is designed to collect data from online customers. Using multiple regression analysis, the relationship between dependent variable (product uncertainty) and independent variables such as product description, third party assurance, website design and customer service is tested. The result shows that all the independent variables are negatively correlated with dependent variable, which means that product description, third party assurance, website design and customer service can be used by online vendors to lessen the problem of product uncertainty in online markets.

These days, businesses, in both online and offline, have started accepting cryptocurrencies as payment methods. Even in countries like El Salvador, cryptocurrencies are recognized as fiat currencies. Meanwhile, publicly known, but not patched software vulnerabilities are security threats to not only software users but also to our society in general. As the status of cryptocurrencies has gradually increased, the impact of security vulnerabilities related to cryptocurrencies on our society has increased as well. In this paper, we first analyze vulnerabilities from the two major cryptocurrency vendors of Bitcoin and Ethereum in a quantitative manner with the respect to the CVSS, to see how the vulnerabilities are roughly structured in those systems. Then we introduce a modified AML vulnerability discovery model for the vulnerability datasets from the two vendors, after showing the original AML dose not accurately represent the vulnerability discovery trends on the datasets. The analysis shows that the modified model performs better than the original AML model for the vulnerability datasets from the major cryptocurrencies.

In remote villages without access to modern IT technology, simple devices such as smartcards can be used to carry out business transactions. These devices typically store multiple business applications from multiple vendors. Although devices must prevent malicious or accidental security breaches among the applications, a secure communication channel between two applications from different vendors is often required. In this paper, first, we propose a method of establishing secure communication channels between applications in embedded operating systems that run on multi-applet smart cards. Second, we enforce the high assurance using an intransitive noninterference security policy. Thirdly, we formalize the method through the Z language and create the formal specification of the proposed secure system. Finally, we verify its correctness using Rushby's unwinding theorem.

This study aims to explore the benefits and extension's role with farmers' markets in USA. This study was conducted by literature review and case study. They help establish connections between consumers and food producers, provide an additional income source for farmers. and in general, serve as a tool for community development. First, from education to advocacy, from research to advising, extension educators have multiple roles to play in promoting the growth of farmers' markets. Second, it is essential that extension engage others who are interested in seeing the markets succeed and create opportunities for such groups to make the market unique in their given communities. Third, extension promotes farmers' markets through the creation and dissemination of how-to publications. These publications typically include tips about having a market establishing a prominent and easily accessible market location, and offering a sufficient product variety to ensure consumer satisfaction. Fourth, efforts by extension offices are already paying off for consumers, vendors, and communities. Involving those who will purchase as well as produce the foods sold at who will purchase as well as produce the foods sold at farmers' markets should diversify the audience extension educators reach. Fifth, extension educators can aid in this effort by encouraging farmers' market vendors to diversify their of offerings and to produce and sell value-added products. Sixth, many extension offices offer guides to the direct marketing venues in their counties, such as farmers' markets, pick your own operations, roadside stands, and community supported apiculture farms. Once such a guide is produced. extension educators can distribute it at workshops and inform local media about the guide so that they can publicize it. Seventh, extension educators should seek to involve those groups who can collaborators could include community economic development organizations, consumer groups, churches, food banks, land preservation organizations, school, farmers' organizations, and other community groups. Eighth, extension educators can also contribute to the improvement of existing markets by offering workshops for vendors in business management, advertizing, marketing, bookkeeping, personnel management, and food preservation. Ninth, farmer's market also provide an opportunity for extension to have face-to face communication with farmers. Tenth, if farmers' markets are well managed, these markets can provide economic, nutritive, educational, social and psychological benefits to venders and the community.

As an engineered product, a software package has multiple dimensions that must be designed judiciously to enhance its competitive viability. Functionality, reliability and price are three such common dimensions. However, many software products are sold as bundles of individual components and the competitive impact of bundling has received less attention in the research literature. In this paper, we examine the implications of software vendors using bundling as an element of competitive strategy. A game theoretic model of the actions of an incumbent and a new entrant is developed and the impact on vendor and consumer welfare is analyzed. Numerical experiments with the model show that (i) increasing bundle size is an effective strategy for the incumbent to increase its payoff at the cost of the entrant's payoff and consumer surplus, especially when the entrant's quality is low (ii) in the presence of bundling, the entrant can still increase its own payoff and consumer surplus at the cost of the incumbent's payoff, by increasing product quality up to the level that best segments market demand with the incumbent and (iii) an increase in bundle size by the incumbent, or an increase in quality by the entrant, can both result in an increase of total surplus. Similar results are observed in a related case where the entrant offers free software bundles. Our results provide insights into how software vendors may strategically use bundling and quality as additional product dimensions in order to stay competitive in the market. These results also inform the competing vendors of the impact of bundling related public policy actions on their respective payoffs.

one of the representative micropayment protocols. The original PayWord system is designed for a user who generates paywords by performing hash chain operation for payment to an only designated vendor. In other words, a user has to create new hash chain values in order to establish commercial transactions with different vendors on the Internet. Therefore, we suggest an efficient scheme that is able to deal with business to different vendors by using only one hash chain operation to supplement this drawback. In this proposed system, a broker creates a new series of hash chain values along with a certificate for the user's certificate request. This certificate is signed by a broker to give authority enabling a user to generate hash chain values. hew hash chain values generated by a broker provide means to a user to do business with multiple vendors.

Researchers have suggested successful risk management as a key factor in successful IT outsourcing projects implementation. The documented investigations, however, have mainly addressed risk management only from a single perspective of either clients or IT vendors. This study explored the potential perception inconsistency regarding the risks between the client and the vendor for IT outsourcing projects by using a quasi-Delphi approach. The analysis results indicated some inconsistencies in the risks perceived by the two parties: (1) the clients regarded (a) lack of vendor commitment to the project and (b) poor vendor selection criteria and process as top critical risks but the vendors didn't; and (2) on the other hand, the vendors perceived (a) unclear requirements and (b) lack of experience and expertise with project activities as significant risks but the clients didn't. Insights into how the client and the vendor perceive risks may help both parties determine how to partner and manage project risks collaboratively to succeed in outsourcing.

This study reviewed current facts on overseas manufacturing factories of garment vendors that were launched in the countries that have a great influence of the Korean Wave, and investigated the influence of Korean Wave in its sourcing area. By doing so, this study aims to present basic data in order to help fabric and garment vendors to enter into the fashion markets of different countries through a local network. For data collection and analysis, Windows SPSS 19.0 was used for frequency analysis of the facts and figures of the local manufacturing factories. In-depth interviews regarding the current facts on local manufacturing factories and the influence of Korean Wave were conducted with 16 Korean garment manufacturing factories in Vietnam and 9 in Indonesia among the overseas garment companies that were registered in the Korean Apparel Industry Association. Through the interview, it was found that new companies should investigate custom tariffs, salary level of the local employees, and infrastructure prior to launching above all. Also, as a result of analyzing competitors and competitive advantages, good treatment of local employees and a good labor environment were noted the most. As for the influence of the Korean Wave, the image of Korea was positive and favorable, but it did not directly affect the preference for Korean companies. After investigating the obstacles that prevented the entrance into local markets, it was found that the rise in the salary level was the biggest hindrance.
