TL;DR: A framework for mobile P2P computing in MANETs (P2P-MANETs) is proposed, including a dynamically priced incentive scheme which rewards users for contributing to the network and a path selection algorithm to allow peers to select how many parts of a file to download from which servers and which paths to satisfy the user's preference for download time and cost.
Abstract: Peer-to-peer (P2P) applications are enormously popular on the Internet. Their uses vary from file sharing to Voice-over-IP to gaming and more. Increasingly, users are moving toward wireless networked devices and wish to continue using P2P applications in these new environments. A mobile ad hoc network (MANET) is an infrastructureless network which allows users to dynamically form a mobile, wireless network. Though P2P and MANETs share some similarities, such as self-organization, dynamism, and resilience to failure, it is necessary to create new P2P algorithms that take advantage of the realities of MANETs. These algorithms must account for the numerous challenges found in these networks, including node mobility, resource constrained nodes, and the necessity of fully distributed algorithms.
In this thesis, we propose a framework for mobile P2P computing in MANETs (P2P-MANETs). Our proposal includes the following components. First, nodes must be able to locate and join the P2P overlay. We therefore propose a fully distributed bootstrapping algorithm in which nodes multicast join requests and cache responses. Next, the overlay peers must form a topology of connections between themselves. We propose a fully distributed topology control heuristic which supports the dynamic nature of the P2P-MANET. It is important that peers contribute to the network by sharing their resources and forwarding traffic for others. We therefore propose a dynamically priced incentive scheme which rewards users for contributing to the network. We also propose a path selection algorithm to allow peers to select how many parts of a file to download from which servers and which paths to satisfy the user’s preference for download time and cost. Finally, we propose a content distribution system that allows users to download large files through the use of network coding and multicasting. Each of these components is the first proposed for its respective place in a P2P-MANET architecture. Simulation results show that each of the proposed components achieves the goals set out for it and outperforms the comparison schemes. The results also show that the overlay topology and path selection heuristics provide good approximations compared to the optimal solutions.

TL;DR: This paper proposes a new cooperation business model in which hybrid traders exist, in which trader cooperates, buys in a lot of goods, and increases own utility, and adopts side payment to promote increasingly cooperation with traders.
Abstract: This paper proposes a new cooperation business model in which hybrid traders exist. We define hybrid traders as new traders on the Internet. Hybrid traders can become both buyers and sellers. We assume that hybrid traders do not have enough money. To buy items cheaply, hybrid traders cooperate with other traders. In regard to buying items, we consider a volume discount-based trading. We propose a mechanism in which trader cooperates, buys in a lot of goods, and increases own utility. Our mechanism adopts side payment to promote increasingly cooperation with traders. Cooperative traders commit participation based on a value of side payment. We extend mechanism which hybrid traders deal with multiple items. This mechanism shows new decision of side payment and proposer’s strategy.

TL;DR: In this paper, the authors examined one dimension of provision in the form of delivery by integrated health and social care teams and by traditional arrangement, and introduced the concept of team capital.
Abstract: Social and health policy analysis is at the heart of ‘value for money’ considerations in public provision and/or production. Economic appraisal is about meeting a potential efficiency test in the use of resources. In an increasingly ‘silver’ society providing for older people in the community, who are over time less likely to be living in a close-knit family, will be a growing resource commitment. Such provision can be organised in a number of ways and as such is an important area for government policy (eg the 2005 Department of Health Green Paper, Independence, Well-being and Choice) and policy appraisal. In particular this paper examines one dimension of provision in the form of delivery by integrated health and social care teams and by traditional arrangement. The analysis covers some of the theoretical and conceptual issues related to modelling ‘integrated’ team production and introduces the concept of ‘team capital’. Some empirical evidence from a three-stage eighteen-month interview based study is r...

TL;DR: In this article, an exploratory essay within the framework of finance theory is presented, which attempts to join two frameworks: information economics and option pricing theory to develop a conceptual signaling model which proposes the firm's investment in real assets as a costly signal of the existence of future investment opportunities.
Abstract: This is an exploratory essay within the framework of Finance Theory. It attempts to join two frameworks: Information Economics and Option Pricing Theory to develop a conceptual signaling model which proposes the firm's investment in real assets as a costly signal of the existence of future investment opportunities. The possible reaction of the capital markets to actual changes of balance sheet data on fixed assets steers the essay. The behavior of economic agents in an informationally asymetric capital market is reviewed with attention to the moral hazard and adverse selection problems. An exploratory research in the brazilian capital market is described in an attempt to investigate possible correlations between balance sheet data and share prices in order to establish conditions and procedures for future research on the
