Offloading Content with Self-organizing Mobile Fogs

Mobile users in an urban environment access content on the internet from different locations. It is challenging for the current service providers to cope with the increasing content demand from a large number of collocated mobile users. In-network caching to offload content at nodes closer to users alleviate the issue, though efficient cache management is required to find out who should cache what, when and where in an urban environment, given nodes limited computing, communication and caching resources. To address this, we first define a novel relation between content popularity and availability in the network and investigate a node's eligibility to cache content based on its urban reachability. We then allow nodes to self-organize into mobile fogs to increase the distributed cache and maximize content availability in a cost-effective manner. However, to cater rational nodes, we propose a coalition game for the nodes to offer a maximum "virtual cache" assuming a monetary reward is paid to them by the service/content provider. Nodes are allowed to merge into different spatio-temporal coalitions in order to increase the distributed cache size at the network edge. Results obtained through simulations using realistic urban mobility trace validate the performance of our caching system showing a ratio of 60-85% of cache hits compared to the 30-40% obtained by the existing schemes and 10% in case of no coalition

A novel alternative. Book groups, women, and workplace networking

Drawing on the results of a small qualitative research project involving four work-based book groups – three in the UK and one in the USA- this article examines the ways in which participation in workplace reading groups facilitates women’s networking within work organizations, in terms of both formal and informal as well as expressive and instrumental networking. It has long been recognized that women’s employment progression is hampered, in part, by their exclusion from male-dominated networks. Taking a gendered approach to the analysis of workplace networking, this study suggests that book groups can function as an alternative to traditional old boys’ networks, in some instances. Within the workplace the collective reading of literature, I suggest, can potentially function as a means to extend the social as well as the more career-focused opportunities of its participants

Pioneers, subcultures and cooperatives: The grassroots augmentation of urban places

About the book: There have been numerous possible scenarios depicted on the impact of the internet on urban spaces. Considering ubiquitous/pervasive computing, mobile, wireless connectivity and the acceptance of the Internet as a non extraordinary part of our everyday lives mean that physical urban space is augmented, and digital in itself. This poses new problems as well as opportunities to those who have to deal with it. This book explores the intersection and articulation of physical and digital environments and the ways they can extend and reshape a spirit of place. It considers this from three main perspectives: the implications for the public sphere and urban public or semi-public spaces; the implications for community regeneration and empowerment; and the dilemmas and challenges which the augmentation of space implies for urbanists. Grounded with international real -life case studies, this is an up-to-date, interdisciplinary and holistic overview of the relationships between cities, communities and high technologies

Networking in the food sector of regional economy

Purpose: The article aims to study the features and the directions of development of network interaction of subjects of the food sector in different regions of the economy. Design/Methodology/Approach: The use of different methodological approaches allowed us to formulate a holistic management concept for the development of a network of competences in the food sector of the regional economy. Findings: The study identified the subjects of such interaction, as well as features that allow them to unite into groups that form networks of competencies. Considering the food sector of the region's economy as a socio-economic system, noted its extreme structural complexity, which necessitates the development of special approaches to its management, or rather the need for structural management is presented. The format of such interaction is a network of competencies, representing a spatially localized socio-economic structure formed on the initiative of active subjects of the regional economy. Practical Implications: The results obtained can be used as a basis for designing a network form of development of the food sector of the region's economy, taking into account the nature of placement and interaction of participants, as well as allowing for effective use of their resource capabilities, experience and knowledge. Originality/Value: In order to overcome the problems associated with the formation of network identity, network management competence is proposed to use a structured approach allowing them to make targeted decisions based on objective conditions and institutional nature.peer-reviewe

KNOWLEDGE ECONOMY AND INNOVATIONS AS FACTORS OF AGRARIAN COMPETITIVENESS

Today, more than ever, development of agriculture leans on science research results and their practical application. Research in the field of agriculture is conducted by large network of public institutions, institutes and universities are mostly directed toward improvement of production. Economical research, at the level of husbandry, market analysis, or analysis and estimations of economic policy is poorly developed. Profitability of agriculture and food industry should be improved and supported by adequate research and application of gained results. Experience acquired in research and education systems of post-communist countries can help these countries change their economy towards knowledge, innovations and new technologies. But, in spite of great number of research workers and successful education system inherited from the communist period, it would be difficult for countries that were part of East Block to turn these potential advantages into commercially successful innovations unless universities and research institutions cooperate closely with private sector, what implies restructuring research system towards adjustment to agro-economy needs.Agro-economy, Cooperation, Performances, Competitiveness, Agribusiness, Community/Rural/Urban Development, International Development, Labor and Human Capital,

Factors influencing intention to create new venture among young graduates

The purpose of this paper is to investigate the factors that are influencing the young graduates for intention to create new venture. The study further highlights how the attraction, networking support, entrepreneurial capabilities, self-independence and self-reliance influence the young students to initiate their new businesses. The sample size of this study was 255 final semester students of various disciplines in different universities from Islamabad and Rawalpindi. The survey based questionnaire was used for data collection. Based on findings this study concludes that all variables, included in the study, play a vital role in new venture creation. Therefore, on the basis of findings this study concludes that young students are more motivated towards new venture creation and start their own businesses.Influencing factors, new venture creation, different disciplines, young graduates, motivation
