Combining an agent-based model, hedonic pricing and multicriteria analysis to model green gentrification dynamics
No full textHousehold mobility dynamics are a complex phenomenon due to the multi-faceted human-environment interactions involved. These dynamics are affected by a variety of variables, spanning economic, structural, political and environmental. With respect to this latter aspect, much research has explored the relationship between the development of urban green areas, the increase of price and the formation of gentrification. Within this context, the present work explores housing mobility and gentrification dynamics proposing a mixed-method approach that combines a spatially explicit agent-based model (ABM), a Multicriteria Decision Analysis (MCDA) and a Hedonic Price (HP). The case study of the transformation project of Victoria Park in Brisbane (Australia) is used to verify the applicability of this integrated approach. In the methodological framework proposed, the ABM simulates the housing mobility of the residents through an individual decision-making process, where the likelihood of mobility is based on various empirical endogenous factors (i.e., household socio-economic characteristics) and exogenous ones (i.e., market variation). The MCDA supports the identification of the relative importance of these factors using a panel of local experts and stakeholders. The Spatial HP explores the impact of urban parks on real estate prices. The current study found the abilities of MCDA and HP to reduce the assumptions of ABM by generating quali-quantitative information of citizens' behaviors and estimating price increase. Moreover, the model highlights the importance of considering both supply and demand sides when analyzing gentrification. The specific results of the case study show the influence of the park in the formation of green gentrification
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
The ground-mounted photovoltaic panel in the Piedmont region
No full textThis Geopackage (GPKG) database contains the ground-mounted photovoltaic panels as in the Piedmont region (north west of Italy).
The acquisition of the polygons was carried out from several basemaps (such as Bing, Google Satellite, Openstreetmap, etc) made available through the QGIS software as XYZ tiles services.
The (manual) recognition activity has been carried out over the last two years without continuity and neither the correctness of the geometries nor the complexity of the information are guaranteed in any way.
The GPKG contains: the database itself, a QGIS project, the layers and the used styles
Regeneration of Rogoredo railway: a combined approach using multi-criteria and financial analysis
No full textAbandoned areas such as neglected railways and urban voids represent a suitable opportunity for the regeneration and requalification of cities, according to the paradigms of sustainability and resilience. Urban transformation and urban regeneration processes are characterized by a high level of complexity, a dynamic behavior over time and interactions between the various actors involved in the process. Within this context, the present paper proposes the application of a combined evaluation framework, based on the integration of Multi-Criteria Decision Analysis (MCDA) with a Financial Analysis (FA) to assess different strategic scenarios for the regeneration of the Rogoredo railways area (Milan, Italy). The purpose of this framework is to take into account the complexity of the decision-making process, considering both the qualitative (social and environmental) and quantitative (economic-financial) aspects. In detail, the railway yards in the Rogoredo area in Milan (Italy) represent an emblematic case. The city of Milan, within the Territory Governance Plan (PGT), has already proposed interventions in this site aimed at reconnecting the infrastructural node and making it an attractive and inclusive pole. The present paper demonstrates the usefulness of evaluation procedures in supporting the entire decision-making process and defining the most suitable scenario considering the initial objective and the stakeholders’ interests. The innovative value provided by this application is represented precisely by the possibility of considering both the developer point of view through FA and the broader public perspective through the support of MCDA. This approach allowed to build and evaluate transformation scenarios capable of both attracting potential investors and promoting sustainable mobility models, social inclusion, eco-sustainable development, improvement of environmental quality through the design of new public areas, green spaces, and services for citizens
Combining Revealed and Stated Preferences to design a new urban park in a metropolitan area of North-Western Italy
Full text linkInclusive and participatory decision-making is a sustainable option for governments and decision-makers to support real transformation and planning of policies and actions. Investigating and gathering the various views and opinions of stakeholders and citizens is particularly effective because it opens up a range of possibilities in co-constructing the city of the future. Among urban areas requiring planning, Urban Green Infrastructures (UGIs) represent spaces designed to improve the character of neighborhoods, as well as to increase the well-being of users. To achieve these goals, planners should adopt a design approach in which UGIs projects are shaped by local community concerns rather than by market conventions in urban design. Focusing on green recreational areas, this study employs an integrated approach combining Revealed (RP) and Stated Preferences (SP) to investigate citizens' preferences regarding urban parks. In particular, the experiment combines Travel Cost Method (TCM) and Discrete Choice Experiment (DCE) for supporting a requalification project in an ex-industrial area of Turin (Italy). In this way, it was possible to understand which facilities can contribute to increasing the citizens’ well-being and the overall efficiency of the UGIs provision and maintenance. The proposed methodology represents an operational and replicable procedure to support different renewal projects in which citizens' opinions are crucial for developing long-term sustainable socio-ecological plans and actions
A Multidimensional Assessment of Ecosystem Services: From Grey to Green Infrastructure
No full textThe notion of Ecosystem Services (ESs) is constantly increasing in interest given their provision of multidimensional values (environmental, social, economic, etc.). Nowadays ESs are at the center of green cities policies tackling the challenges of sustainability. More than 55% of the population is already living in urban areas, and this number is still rising. Within this context, challenges for sustainable development considering a circular economy perspective will be more concentrated in cities and in particular urban green spaces where strategies could be more effective for achieving sustainable urban development goals, such as improving public health, preserving biodiversity, reinforcing social cohesion, supporting the economy, providing opportunities for recreation, and helping in adapting to climate change. More specifically, the role of urban green spaces is testified by many green infrastructures policies proposed by different cities around the world. Rooftops, abandoned infrastructures and downgraded areas are some of the places that can be reused for creating new natural and green spaces within cities. Given these premises, the present paper aims to investigate the role of green areas in urban context in improving the overall quality of the space and in providing multidimensional benefits. The innovation of the present paper regards the integration of cost-based and value-based methods for the assessment of ESs. Starting from a real case study located in the city of Milan, the article illustrates the potential of combining the valuation of biophysical and economic values
Supporting the Management Plan of a World Heritage Site Nomination Through a Multi-step Evaluation Approach
No full textThe nomination of a site to the World Heritage List must be supported by a nomination document and a management plan. The management plan emphasizes the Outstanding Universal Value of the site, as well as it defines protection objectives and how to pursue them. However, neither UNESCO documents nor research applications provide a shared framework for the tools or methodologies that can support the different phases of the management plan. Within this context, the present paper started with an analysis of both management plans already implemented for UNESCO-listed sites and contributions provided by research applications. The result of this in-depth analysis suggests the proposal of a multi-step approach able to guide the entire decision-making process and to support the development of the management plan of a World Heritage Site nomination required by the World Heritage Convention. This approach could rep-resent a guiding tool for researchers, practitioners, and decision-makers in the case of real-world site nomination and management for the World Heritage List. The mixed-method approach proposed starts with framing and structuring goals, objectives and values, as well as actors and stakeholders involved, and ends with the design, evaluation and monitoring of the project strategies. In particular, the proposed methodology for developing the management plan of a World Heritage-nominated site is constituted by four main working phases: (1) the problem framing and structuring, (2) the analysis of risks and resources, (3) the design of the strategies, and (4) the evaluation and monitor-ing phase. Each of these phases is supported by specific assessment methods and tools, both qualitative and quantitative
