Studying How E-Markets Evaluation Can Enhance Trust in Virtual Business Communities
One of the major drawbacks of conducting business online is the raised level of risk associated with business transactions. Potential business partners usually have limited information about each others reliability or product / service quality before an online transaction. In this paper, we focus on the problem of selecting a trustful electronic market (e-market), in order to perform business transactions with it. In particular, we examine how the decision of selecting an appropriate e-market can be facilitated by an e-market recommendation algorithm. For this purpose, a metadata model for collecting and storing e-market evaluations from the members of a virtual business community in a reusable and interoperable manner is introduced. Then, an e-market recommendation algorithm that can synthesize existing e-market evaluations stored using the metadata model, is designed. Finally, a scenario of how the presented e-market recommendation algorithm can support a virtual agribusiness community of the organic agriculture sector is discussed.E-market, metadata, recommender system, virtual community, Institutional and Behavioral Economics, Marketing,
An orthonormalization method for the approximate conformal mapping of multiply-connected domains
We consider the use of an orthonormalization method for constructing approximations to one of the standard conformal maps for multiply-connected domains. The method has been used successfully in [12], but only for the mapping of doubly-connected domains. Our purpose here is to consider its application to the mapping of domains whose connectivity is greater than two
The bergman kernel method for the numerical conformal mapping of simply connected domains
A numerical method for the conformal mapping of simply-connected domains onto the unit disc is considered. The method is based on the use of the Bergman kernel function of the domain. It is shown that, for a successful application, the basis of the series representation of the kernel must include terms that reflect the main singular behaviour of the kernel in the complement of the domain
Developing a smartphone app for m-government in agriculture
The high penetration of smartphones and the advanced capabilities of the software that they can host, forces public agencies to rapidly transform their services in the mobile government environment for maximizing utility of services and minimizing costs. In this context, the aim of the paper is primarily to review the smartphone use and capabilities in agriculture. An overview of apps targeted to the agricultural business sector is provided. Secondly, the potential use of smartphones for mobile government is discussed and a transactional mobile government app for the Android operating system is proposed based on a case study for agriculture. The mobile government app is based on a previously developed electronic government system for farmers. Design and technical aspects for the implementation of the proposed app are presented and discussed. Such apps seem to be a promising solution for farmers enabling them to access government information and transact with public agencies at their convenience and at a location of their choice.</jats:p
A Survey of Greek Agricultural E-Markets
The role that information technology plays in today’s business activities has led to an increase in firms using and/or deploying e-markets online. This development undoubtedly affects the agri-food sector, since a large number of agricultural firms are demonstrating or are expected to demonstrate e-commerce activities. This paper aims to provide an overview of the current status of agricultural e-markets in Greece, by presenting results from an analysis of 100 cases. Results indicate that Greek e-markets may still have a rather low degree of sophistication, but they demonstrate a strong B2B orientation, as well as an outreach for international customer bases.Internet, e-commerce, e-markets, agriculture, agri-food sector, survey, Consumer/Household Economics, Marketing,
ICT and farmers : lessons learned and future developments
Information and Communication Technologies (ICT) evolution is well advancing Moore?s Law prediction of geometric progression of computer performance indexes. Indeed, these technologies are not only fast developed but, in addition, are giving birth to newer ones nicely branching existing “old fashion” ICT systems and tools. These innovations of ICT are not only regenerating traditional sciences, like Agriculture, and practices, like farming, but also, awake well neglected human sensitiveness and indifference for poverty, environmental protection, climatic deterioration issues and the future of our planet as a whole. To refer to a few examples of these innovations affecting Agriculture and Environmental Sciences: Cloud Computing provides equality in resources management and exploitability to small budget farms against the big ones. Web2 browser allows, as a platform, effective runtime environment and considerably easy access to applications by farmers lacking proper education and training. Parallel Computing brings exponentially increased core processing to low-end computers facilitating the use of huge computer power by small agricultural research units. Never the less agricultural and farming communities, in their majority, do not adopt new ICT tools and systems to the degree required for substantial agricultural development. In this paper, experience gained over the years is used to evaluate and reason poor performance in the area of applicability of ICT innovations and tools by the vast majority of farmers throughout the world.</jats:p
Driving Web 2.0 Tool Adoption in Agricultural Education
The new opportunities for collaboration, participatory content creation and communication offered through the advancements of Web 2.0, such as social networking, blogs, wikis, video sharing and other, are creating new learning models. In turn, tutors cannot ignore this trend and have to bear the responsibility of incorporating Web 2.0 tools in formal, informal, work-based and vocational education and approach their students in a very familiar and favourable way. In this context, this paper tries to highlight the need for enhancing tutors’ skills and drive Web 2.0 tool adoption in educational practice. Thus, it draws upon the successful example of a European project regarding agricultural tutors’ training on Web 2.0 tools. The challenge for all agricultural tutors is how to integrate Web 2.0 tools into current curricula and education.</jats:p
Online educational repositories for promoting agricultural knowledge
Towards promoting sustainable agriculture and economic growth, the development of the agricultural workforce and set up of innovative agricultural systems are required. Agricultural educational repositories are systems used for storing, reusing and sharing agricultural learning resources. They contribute to agricultural education at different educational levels and target groups. Thus, this paper firstly provides an overview of Institutional Repositories (IRs) and Open Access Archives (OAAs) in Greece and agricultural repositories worldwide. Also, it describes the agricultural repositories that provide access to educational content in Greek and presents experiences from the establishment of Agricultural University of Athens’ (AUA) repository.</jats:p
