Alternative Models for the City-Density: The Case of Lazar Khidekel
No full textThis paper intends to propose a reflection on the issue of urban form, in particular, on the tendency, today homologating, of constructing new parts of the city by following a vertical densification model. Through the selection of case studies considered significant, this work will approach some research that investigated the possibility of dealing with the problem of urban density and land consumption through an alternative scenario. The cases presented include some experimental projects developed within the framework of the Soviet city developed at the beginning of the twentieth Century. The debate of those years— particularly from 1929 to 1931—was of fundamental significance for the development of soviet urban design, and today, it still constitutes one of the most important moments in the research for new forms of settlement and new ways of life for contemporary society. In this context, the experience of Lazar Khidekel raises particular interest, and the settlement aspect of his experimental projects will be analysed. Khidekel's aero-cities develop the idea of a settlement generated by the superimposition of linear structures elevated mechanically above the ground, which represented a solution for preserving the soil addressing the issue of density, from which it is possible to derive some principles susceptible to innovative development
New paradigms for city management and planning. From Open Data Knowledge Sharing Platforms to e-participation
No full textFor several years now, society has been transforming itself into a virtual society, at different intensities and speeds. The health emergency we are experiencing has accelerated this change also in the Public Administration, one of the contexts that has always presented major difficulties in the field of digitization, but which can benefit more from it in terms of simplification and transparency of processes.
The intrinsic capacity of the virtual society, to be unlinked from spatial constraints in the construction of knowledge and in the capacity for renewal, assumes a central role in solving problems due to the coexistence of interests and positions of a very different nature (different stakeholders).
One of the areas that could benefit from a digital transition is Planning, specifically in relation to participatory processes. Recalling one of the principles of the Charter of Public Space, according to which the design of public space should involve, through participatory processes, every individual citizen, it is
useful to consider that the wider the perimeter of participation, the wider the possibility of obtaining indications that are genuinely shared within civil society.
The adoption of ICT (Infomation and Communication Technologies) can therefore allow the achievement of a greater number of city-users, building an in-depth knowledge of the territory both from an objective technical point of view, through the mapping of spaces and their technical characteristics (through BIM and
GIS technologies) and through participatory processes, which can define a scheme of the needs of all the subjects who insist on the territory, optimizing the definition of hypothetical scenarios.
The research is proposed as a moment of advancement in disciplinary practices aimed at experimenting with new frontiers of participatory planning. The use of ICT tools, whose operational impact integrates and improves current and future scenarios, allows to verify an operational model that, through the interaction
and interoperability between the different actors, is able to manage the uses and transformations of the territory in the process of urban regeneration and regeneration
Genesis of Hopley Farm informal settlement in independent Harare, <i>Zimbabwe</i>
No full textConventional studies on informal urbanism in Zimbabwe focused more on efforts in upgrading informal settlements but did not address their genesis. I argue that finding sustainable solutions to addressing informal settlements challenges and enhancing their liveability must be premised on exploring the factors influencing their genesis and temporal changes. Data were collected from Hopley Settlement, Harare, through interviews with 20 household heads and purposively selected key informants with a stake in human settlement planning. Findings suggest that the genesis of informal settlements in post-independent cities is complex and is influenced by politics, segregating the poor, constrained municipalities, and poor planning.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
Get PDFWe 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
