Digital informalisation: rental housing, platforms, and the management of risk
Full text linkThe eruption of disruptive digital platforms is reshaping geographies of housing under the gaze of corporations and through the webs of algorithms. Engaging with interdisciplinary scholarship on informal housing across the Global North and South, we propose the term ‘digital informalisation’ to examine how digital platforms are engendering new and opaque ways of governing housing, presenting a theoretical and political blind spot. Focusing on rental housing, our paper unpacks the ways in which new forms of digital management of risk control access and filter populations. In contrast to progressive imaginaries of ‘smart’ technological mediation, practices of algorithmic redlining, biased tenant profiling and the management of risk in private tenancies and in housing welfare both introduce and extend discriminatory and exclusionary housing practices. The paper aims to contribute to research on informal housing in the Global North by examining digital mediation and its governance as key overlooked components of housing geographies beyond North and South dichotomies
Smart mobile networks with intelligent physical layer actuating mobility management
No full textThe factors that will drive the ontogenesis of next generation mobile networks namely are the evolution of the mobile devices and ever incremental demand for data traffic triggered by the proliferation of smart phones and the dongles. Apprehending an exponential growth in numbers of the mobile users, the cell size of the mobile network will shrink. Eventually, there will be an upsurge of signalling messages interchanged between the device and the network due to an increase in handover related operations. Attempt should be made to reduce the interaction with the network and to simplify the mobility and location management related processes. Also to consider is the ever increasing demand for data traffic triggered by the new generation mobile devices. In this paper, we set out a technical architecture of a mobile network to abridge the intricate mobility and location management processes as well as the addressing principle to render more operational efficiency and cater to the needs of the data hungry applications that we envisage for the next generation devices and networks
Rendering intelligence at physical layer for smart addressing and multiple access
No full textThe primary objective of this work is to propose a technique of wireless communication, where we render intelligence to the physical layer. We aim to realize a physical layer that can take part in some processes which is otherwise confined to higher layer signalling activities, like for example addressing of a node. For a typical closed user group type of network, we propose a multiple access mechanism and network topology which will not only eliminate the need of intelligent core network equipments in the network area , but to use this intelligent physical layer to directly reach any node over the air interface in the coverage area. This system is presence agnostic, hence the network is not aware of the exact location of the mobile node in the network area. So the mobility management process is not to be seen here. Also the network does not follow any cellular topology. This paper addresses the fundamentals behind the proposed multiple access scheme and draws out the benefits compared to the existing multiple access processes based on cellular approach
Platform economies and urban planning : Airbnb and regulated deregulation in London
Full text linkThe 'sharing economy' has become a new buzzword in urban life as digital technology companies set up online platforms to link together people and un- or underutilised assets with those seeking to rent them for short periods of time. While cloaked under the rhetoric of 'sharing', the exchanges they foster are usually profit-driven. These economic activities are having profound impacts on urban environments as they disrupt traditional forms of hospitality, transport, service industry and housing. While critical debates have focused on the challenges that sharing economy activities bring to exist- ing labour and economic practices, it is necessary to acknowledge that they also have increasingly sig- nificant impacts on planning policy and urban governance. Using the case of Airbnb in London, this article looks at how these sharing or platform economy companies are involved in encouraging gov- ernments to change existing regulations, in this case by deregulating short-term letting. This has important implications for planning enforcement. We examine how the challenges around obtaining data to enforce new regulations are being addressed by local councils who struggle to balance corpo- rate interests with public good. Finally, we address proposals for using algorithms and big data as means of urban governance and argue that the schism between regulation and enforcement is open- ing up new digitally mediated spaces of informal practices in cities
Challenges for Coexistence of Machine to Machine and Human to Human Applications in Mobile Network: Concept of Smart Mobility Management
No full textA key factor for the evolution of the mobile networks towards 4G is to bring to fruition high bandwidth per mobile node. Eventually, due to the advent of a new class of applications, namely, Machine-to-Machine, we foresee new challenges where bandwidth per user is no more the primal driver. As an immediate impact of the high penetration of M2M devices, we envisage a surge in the signaling messages for mobility and location management. The cell size will shrivel due to high tele-density resulting in even more signaling messages related to handoff and location updates. The mobile network should be evolved to address various nuances of the mobile devices used by man and machines. The bigger question is as follows. Is the state-of-the-art mobile network designed optimally to cater both the Human-to-Human and Machine-to-Machine applications? This paper presents the primary challenges for the coexistence of M2M and H2H devices in a mobile network and draws emphasis for revisiting the mobility management aspects and congestion control in the-state-of-the-art network. Further, we set out a mobile network architecture with smart mobility management which aims to reduce the signaling interaction between the device and the network to optimise the power and bandwidth
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Nano mobile network based on smart location management and addressing
No full textThere has been a significant emphasis on applications of nanotechnology in mobile communications, especially, to redesign the mobile devices for M2M and P2P applications. Due to constraints in power output and an apprehension for explosive growth in nano devices in future, the cell size of the mobile network will shrink. This will lead to a rise in signalling messages interchanged between the device and the network due to an increase in handover related operations. Attempt should be made to reduce the interaction with the network and to simplify the mobility and location management processes. Also, to be considered is the ever increasing demand for data traffic triggered by the proliferation of new generation mobile devices. This paper presents a mobile network architecture based on a novel addressing principle to make more efficient and less complex the mobility and location management processes
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
