Planning the 15 min city-the case of Chania
Full text linkBook of proceedings: 35th AESOP Annual Congress Integrated planning in a world of turbulence, Łódź, 11-15th July, 2023According to C40 Cities Climate Leadership Group & C40 Knowledge hub, adopting a 15 minute city strategy means striving for an urban model that allows everyone, in every neighborhood, to meet most of their daily needs within a short walk or bike ride of their home. The current paper will examine the possibilities of a typical Greek city, Chania, to be developed as a 15minute city. The city is chosen as it combines dense development in its historic center, and sprawled development in its borders, so these contradictions are decisive for its sustainable mobility development. Its inhabitants and visitors mostly use cars for their daily needs fact that is caused by the lack of pedestrians and cyclist networks and the fragmental way public uses and areas have been diachronically developed in the city. Research will examine the positions of public uses and areas, their connections with mobility networks and it will evaluate their accessibility. Finally, it will propose strategies for the adjustment of the city in the principles of the 15-minute city.

Evaluation of healthy historic centers: The case of Chania
Full text linkThis paper explores the concept of healthy cities, emphasizing the need for urban environments that promote health, well-being, and sustainability. It highlights the challenges posed by rapid urbanization, environmental degradation, and social inequalities. The World Health Organization’s definition of a healthy city is outlined, emphasizing the integration of physical and social environments to enhance quality of life. The paper reviews existing evaluation frameworks and certifications and proposes a toolkit for assessing the health of historic urban centers, incorporating factors like cultural heritage preservation, tourism, and social equity. The historic center of Chania which is used for the application of the proposed evaluation framework is characterized by moderate preservation, with signs of deterioration in some buildings and limited adaptive reuse. Environmental quality is relatively good, but noise pollution and low green space coverage are concerns. Accessibility for people with disabilities and public transportation services are inadequate, while cycling infrastructure is poorly developed. Climate resilience is weak, and sustainable tourism efforts are insufficient, leading to overcrowding and strain on infrastructure. Proposals for improvement include enhancing heritage preservation, expanding sustainable transport, increasing green spaces, and strengthening climate resilience. These measures aim to improve accessibility, livability, and sustainability for both residents and visitors
Planning resilient cities: The case of Chania
Full text linkToday’s societies face intense problems caused by rapid urbanization and land degradation, globalization and socio-economic poverty, global warming and climate change that affect the world and can be the cause of natural disasters. According to the United Nations ‘‘urban risk, city planning and the role of local governments in dealing with risk reduction have been recognized as key factors to build resilient communities and nations’’ (United Nations, 2010) Physical exposure to disasters can affect not only the informal settlements that carry physical vulnerabilities due to their location or construction practices. In many cases, ‘‘formal’’ urban areas are as well vulnerable due to the absence of adequate building standards and urban planning that would reduce disaster risk by physical exposure. The current paper will focus on the coastal city of Chania and its vulnerability because of the lack of urban planning. The case study is selected because it concentrates the characteristics of a typical coastal Greek city, which faces rapid demographic growth and unplanned urban and touristic expansion. The examined city has been diachronically influenced by the liberalization of construction regulations, an unqualified private sector emerged, hastily developing housing mostly with government oversight and without building permits
Public spaces and neoliberal policies: The Greek case
Full text linkThe process of neoliberalizing public spaces involves implementing policies aimed at increasing capital flow to offset reductions in local budgets. In Greece, although public spaces are decisive elements of the urban tissue, the tools, strategies, and mechanisms for their development are mainly based on public funding and the role of the private sector is still weak. The current paper analyzes the policies for public spaces since 1950 until today and the role of public and private sectors in their development. It focuses on specific periods as the Olympic Games, the economic crisis and today, to investigate the policies followed for public spaces development. The research area is the capital of Greece, and the examined case studies include both small- and large-scale areas to cover different types of public spaces. Research focuses on the changes in the legislative framework to promote the role of private sector and evaluates its role and collaboration with the public sector. The analysis of the case studies shows that constrained expertise, centralized decision-making procedures, and inadequate coordination of synergies among management entities, have resulted in notable deficiencies in the partnerships between the public and private sectors in supporting projects for the regeneration of public areas
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
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
