Urban Policy Sustainability through a Value-Added Densification Tool: The Case of the South Boston Area
Full text linkOver the past decade, urban density has been growing faster than ever, forcing high-density expansion. The aim of this study is to verify whether urban density is accepted as a sustainable value-added quality, internalized in the willingness to pay on a buildable per square feet basis. To explore the relationship between land prices and densification processes, this study focused on a low-density area, which recently went through a densification policy process with the approval of a new zoning tool. The study analyzes land price trends on a 144-Acre of area, located in the South Boston Submarket, identified as the Dorchester Ave Area. I analyzed land transactions in this area between 2012 and 2021. I also examined land price variations before and after the approval of a densification plan in correlation with the overall trend of the real estate market in that area. The results suggest that density is a value-added feature that affects land prices. Indeed, a higher density leads to higher values per buildable square feet. Densification policies have a strong positive impact on land transaction prices. Community and developers valued density with a greater willingness to pay, internalizing the economic, social, and environmental sustainability benefits. This phenomenon should be taken into consideration by local public authorities implementing their zoning tools
A Fuzzy Logic Application to Manage Construction-Cost Escalation
Full text linkIn large-scale projects, such as transport infrastructures, the cost-planning phase stands out as one of the most crucial for the project's success. Cost and time overruns, during the construction phase, are often the cause of project failure. A meticulous, conscious, and accurate ex-ante analysis of cost and time assessment can greatly contribute to the efficient and effective completion of a project. Various approaches have been developed to estimate and mitigate cost overruns. Such mitigation is subject to careful analysis of project risks, encompassing construction, environmental, social acceptance, and market risks. In this contribution, we propose the implementation of the risk-assessment tool, suggested by the National Anti-Corruption Authority (ANAC), using fuzzy logic to enhance its effectiveness. Thanks to the implementation of fuzzy prioritizations, the risk matrix and the associated risk levels, which are obtained by combining the event's probability of occurrence and its expected impact on costs, have been clearly and structurally defined. This tool can facilitate risk ranking and, therefore, the implementation of their management strategies during the design and construction phases as well as the consensus-creation process. This application can therefore be used by public authorities as a transparent and manageable tool to assess expected risk during the design and implementation phases of the project
Renewable Energy Community: Opportunities and Threats towards Green Transition
Full text linkThe European Union faces a complex economic conjunction where different factors affect and reduce the number of feasible and sustainable projects according to the legislation and the available resources. In this context, one of the available solutions to the current energy crisis could be the implementation of Renewable Energy Communities (RECs) to support the European dual transition targets. The idea of an energy community is still being defined in the literature and from a legislative perspective. The increasing REC dimension and numerosity demand in-depth studies on opportunities and threats in a still unexplored market. To clarify the Italian and European state of the art of these communities, this study in the first section addresses the socioeconomic and policy conditions needed for the foundation and development of energy communities by analyzing the in-force legislation. The analysis of the current regulation has been conducted to verify how RECs affect local communities and their degrees of freedom and action in regions. The second part of the study aimed to define threats and opportunities in creating new professional profiles and local job opportunities in this new thriving market. In this study, we collected interviews and surveys with market operators, both on the service providers' side (ESCo) and the communities' side (promoters), to identify conflicts and advantages associated with establishing communities. The participants were initially selected through publicly available lists, and after verifying the contact correctness, they were contacted by email or phone. The results of the interviews have been processed into a SWOT analysis, showing how national policies currently need to catch up in implementing this efficiency tool and how the restricted number and the variety of the existing communities increase the difficulty in creating cohesive and universal guidelines. Finally, local markets can still not correctly manage this innovative tool's uncertainty despite being interested in it
The Evaluation of Sustainable Development Projects in Marginal Areas: An A’WOT Approach
Full text linkThe increasing urbanization trend, projected to reach 70% of the global population residing in cities by 2050, underscores the pivotal role of cities in achieving the Sustainable Development Goals (SDGs) set by the 2030 Agenda for Sustainable Development (UN, 2015) and combating climate change. Nonetheless, the 2023 report by the United Nations Human Settlements Programme (UN Habitat) reveals an alarming gap in achieving SDG 11 “Sustainable cities and communities” by 2030. This gap highlights the urgent need for transformative shifts in urban policies and investments to prevent cities from becoming centers of global disparities, including socio-economic inequalities, digital divide, and spatial fragmentation, particularly in marginal areas. Marginal areas suffer indeed from conditions of sub-optimality in planning capacity, valuable decision-making, and project implementation. The inadequate planning, management, and governance of marginal areas, coupled with suboptimal investments, can severely compromise their socioeconomic condition. Planning efforts frequently fall short in achieving long-term sustainability goals due to localized and short-sighted decision-making processes, particularly evident in marginal areas. It is crucial, though, to support their public administrations in the achievement of the SDG 11 targets and in their responsive participation in the calls for the allocation of public funding. In this paper, we provide a theoretical and methodological approach to evaluate urban regeneration projects in marginal areas. In detail, we develop an A’WOT approach, which combines a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis to the Analytic Hierarchy Process (AHP), to rank alternative urban development projects
Towards European Transitions: Indicators for the Development of Marginal Urban Regions
Full text linkUrban transitions and urban-scape have been heavily impacted by the COVID-19 pandemic and will likely be affected by the current Ukrainian-Russian conflict. These two major events have affected European urban regions and especially marginal regions. Indeed, these regions are mostly struggling with inequality, lack of optionality, interoperability, and resilience due to their energy dependency and digital asymmetries. The continuous demand for a green and digital transition to strengthen social and economic resilience sought and targeted by the European Community has driven the policy of recent years to new European Guidelines. Nevertheless, the digital transition will require sustainability targets in the urban context, changing economic, social, and ecological relationships and balances. In this context, faced with these new transitions, marginal urban regions must plan, design, build, and manage future urban planning choices in a new digital-hybrid space. Therefore, it is crucial to support these transitions with a multi-dimensional sustainability concept through economic, environmental, social, and digital measurements. Urban sustainability indicators (USIs) play an essential role in supporting urban choices and planning. The current study analyzes recent literature and European standards to verify if and how they have changed in embracing the European Policy Pillar under a new and different sustainability profile, which needs to include digital sustainability. As a matter of fact, even if the concept of digitization has been recognized as a pillar of ongoing transitions, the literature and even European indicators struggle to recognize it as a tangible and measurable indicator of sustainability. Seeking to bridge the gap between European requirements and urban practice, the aim of this study is to identify and suggest new key indicators of digitalization to enable the digital sustainability of urban planning to be measured. These indicators can be used to implement a new valuation tool capable of supporting marginal regions by promoting sustainable urban investments in this new hybrid space
Il Valore Di Vendita Forzata Degli Immobili A Garanzia Dei Crediti
Full text linkAs a consequence of the long lasting crisis that begun in 2006, the evaluation of collaterals and guarantees become a key issue. The global financial crisis had actually a heavy relapse on loans supply. The decrease of new granted mortgages was mainly related to the weakness and decline of the housing market and the negative phase of the economic cycle, characterized by an increase in the unemployment rate and a reduction in household incomes. In this context, robust risk assessment procedures and proper evaluation of collaterals are required for lending institutions to the granting of loans. The aim of this paper is to investigate whether assets used as collaterals are overestimated and how much of the mortgage lending value (VC) can be recouped by the property forced sale price (VF). The present study analyses the Italian foreclosed homes market, by surveying 89 forced sales, which occurred between 2006 and 2014 in the provinces of Treviso, Venice and Padova
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
