A framework for the dynamic management of Peer-to-Peer overlays

Peer-to-Peer (P2P) applications have been associated with inefficient operation, interference with other network services and large operational costs for network providers. This thesis presents a framework which can help ISPs address these issues by means of intelligent management of peer behaviour. The proposed approach involves limited control of P2P overlays without interfering with the fundamental characteristics of peer autonomy and decentralised operation. At the core of the management framework lays the Active Virtual Peer (AVP). Essentially intelligent peers operated by the network providers, the AVPs interact with the overlay from within, minimising redundant or inefficient traffic, enhancing overlay stability and facilitating the efficient and balanced use of available peer and network resources. They offer an “insider‟s” view of the overlay and permit the management of P2P functions in a compatible and non-intrusive manner. AVPs can support multiple P2P protocols and coordinate to perform functions collectively. To account for the multi-faceted nature of P2P applications and allow the incorporation of modern techniques and protocols as they appear, the framework is based on a modular architecture. Core modules for overlay control and transit traffic minimisation are presented. Towards the latter, a number of suitable P2P content caching strategies are proposed. Using a purpose-built P2P network simulator and small-scale experiments, it is demonstrated that the introduction of AVPs inside the network can significantly reduce inter-AS traffic, minimise costly multi-hop flows, increase overlay stability and load-balancing and offer improved peer transfer performance

Regulating competition in the digital network industry: A proposal for progressive ecosystem regulation

The digital sector is a cornerstone of the modern economy, and regulating digital enterprises can be considered the new frontier for regulators and competition authorities. To capture and address the competitive dynamics of digital markets we need to rethink our (competition) laws and regulatory strategies. The thesis develops new approaches to regulating digital markets by viewing them as part of a network industry. By combining insights from our experiences with existing regulation in telecommunications with insights from economics literature and management theory, the thesis concludes by proposing a new regulatory framework called ‘progressive ecosystem regulation’. The thesis is divided in three parts and has three key findings or contributions. The first part explains why digital platforms such as Google’s search engine, Meta’s social media platforms and Amazon’s Marketplace are prone to monopolization. Here, the thesis develops a theory of ‘digital natural monopoly’, which explains why competition in digital platform markets is likely to lead to concentration by its very nature.The second part of the thesis puts forward that competition in digital markets persists, even if there is monopoly in a market. Here, the thesis develops a conceptual framework for competition between digital ecosystems, which consists of group of actors and products. Digital enterprises compete to carve out a part of the digital network industry where they can exert control, and their strong position in a platform market can be used offensively or defensively to steer competition between ecosystems. The thesis then sets out four phases of ecosystem competition, which helps to explain when competition in the digital network industry is healthy and when it is likely to become problematic.The third and final part of the thesis brings together these findings and draws lessons from our experiences of regulating the network industry for telecommunications. Based on the insights developed in the thesis it puts forward a proposal for ‘progressive ecosystem regulation’. The purpose of this regulation is to protect and empower entrants from large digital ecosystems so that they can develop new products and innovate disruptively. This regulatory framework would create three regulatory pools: a heavily regulated, lightly regulated and entrant pool. The layered regulatory framework allows regulators to adjust who receives protection under the regulation and who faces the burdens relatively quickly, so that the regulatory framework reflects the fast pace of innovation and changing nature of digital markets. With this proposal, the thesis challenges and enriches our existing notions on regulation and specifically how we should regulate digital markets

Invention and Resistance: FabLabs against Proletarianization

The contemporary philosopher Bernard Stiegler has reopened the debate on the historically Marxist concept of proletarianization. Whereas Marx and Engels define the term as the continued expansion of an economic class that must sell their labour to the owners of the means of production, Stiegler argues that proletarianization is better understood as the gradual erosion of know-how (savoir). He attributes this erosion to a societal mismanagement of technological change. Starting from the premise that technological objects are material externalizations of capacities that previously inhered in the human, Stiegler asserts that we have systematically failed to compensate for these technological externalizations with the acquisition of new capacities, specifically those that would allow us to participate in technology's continuous evolution. As a consequence, this new technologically illiterate proletariat must constantly react to technological changes that are always developed elsewhere. This thesis contributes to the debate on proletarianization by investigating a network of digital fabrication workshops called Fabrication Laboratories, or FabLabs. Part of the broader 'maker' movement, an international community of people who make their own things and electronics, FabLabs are committed to democratizing access to the means of digital fabrication. Unlike other community-based workshops or shared machine shops, their goal is to build a global network of local labs that share similar capacities. Similar to the free and open source software movement, the FabLabs promote decentralized organizational structures and horizontal hierarchies both within and between labs. My aim is to investigate the extent to which the FabLabs can be considered sites of de-proletarianization. In so doing, I build on Stiegler's work to propose my own definition of proletarianization as a process that weakens our individual and collective abilities to pose and respond to political, social, and economic problems. This process has been driven by an acceleration in the rate of technological change that has not been matched with a commensurate cultivation and distribution of the capacities that would allow people to problematize and participate in the technological evolution of their societies. As a result, the problems we face as individuals, collectives, and as a species, are increasingly conditioned by technological artifacts that we grasp inadequately as users and consumers. Based on an ethnographic study of grassroots labs in France, Germany, and Hungary, I argue that FabLabs have a significant de-proletarianizing potential because they encourage people to problematize the technological conditions of society and develop the capacities necessary to change those conditions. However, FabLabs have thus far had a minimal de-proletarianizing effect on the societies in which they operate, largely due to their limited, and relatively homogeneous, membership base. They have also struggled to apply their principles of decentralization and flat hierarchies to the political structuring of the labs themselves, thereby undermining the abilities of their members to pose problems that are not just technological, but political as well. Underlying this investigation is an ontological framework that is capacities-based, pluralist, and non-anthropocentric. Inspired by the works of Gilles Deleuze and the object-oriented ontologist Levi Bryant, I argue that all beings, humans and nonhumans, are defined by their capacities to affect, to be affected, and to resist. This ontological framework allows me to develop different concepts of invention and resistance that are integral to both my theorization of proletarianization and my assessment of the FabLabs as sites of de-proletarianization

Area-wide Integrated Pest Management

Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, including non-target species, air, water and soil. The extensive reliance on insecticide use reduces biodiversity, contributes to pollinator decline, destroys habitat, and threatens endangered species. This book offers a more effective application of the Integrated Pest Management (IPM) approach, on an area-wide (AW) or population-wide (AW-IPM) basis, which aims at the management of the total population of a pest, involving a coordinated effort over often larger areas. For major livestock pests, vectors of human diseases and pests of high-value crops with low pest tolerance, there are compelling economic reasons for participating in AW-IPM. This new textbook attempts to address various fundamental components of AW-IPM, e.g. the importance of relevant problem-solving research, the need for planning and essential baseline data collection, the significance of integrating adequate tools for appropriate control strategies, and the value of pilot trials, etc. With chapters authored by 184 experts from more than 31 countries, the book includes many technical advances in the areas of genetics, molecular biology, microbiology, resistance management, and social sciences that facilitate the planning and implementing of area-wide strategies. The book is essential reading for the academic and applied research community as well as national and regional government plant and human/animal health authorities with responsibility for protecting plant and human/animal health

Social work with airports passengers

Social work at the airport is in to offer to passengers social services. The main methodological position is that people are under stress, which characterized by a particular set of characteristics in appearance and behavior. In such circumstances passenger attracts in his actions some attention. Only person whom he trusts can help him with the documents or psychologically
