There is a growing number of processes in Brazilian cities that have been identified as gentrification. However, the classic definition of gentrification as a process of transformation of existing urban housing stocks by new homeowners with a higher socio-economic profile poses challenges to understand recent empirical data coming from Brazil and the Global South more generally. Instead of dismissing them as deviant cases, this paper challenges the Northern empirical foundations of gentrification theory and calls for a new methodological approach to both classic and new cases that take into consideration its contextualization. This new framework for gentrification research is based on necessary dimensions that identify the production of gentrifiable space as the initial condition to the process of socioeconomic change with displacement in which built-environment upgrades constitute one of its most visible feature. These dimensions are present in each and every case, bounding the concept and operationalizing research, while local mediating forces make gentrification context-specific. Therefore, urban studies on gentrification. Should understand and explore the nature of these differences, in a return to in-depth studies and empirical research, opening spaces for de-centering positions and building theory from multiple positionalities.

Managerial competencies, defined as the “underlying characteristics of an individual that have a causal relationship with effective or superior performance in the job” (Boyatzis, 1982, p. 12), are key to achievement of productive purposes in the Huila department, in Colombia. The present article, as an investigative result, seeks to identify those managerial competencies, both current and required, of the organizational leaders in the Passifloraceae productive sector in the Huila department, in Colombia. The epistemological paradigm used in this article is that of interpretivism. The reasoning method is deductive, and the methodological approach is mixed. The unit of analysis for this study consists of the directors of the associative organizations of Passifloraceae producers in the productive chain, where two types of players are identified: thirteen (13) leaders of organizations producing passion fruit, and five (5) representatives of institutions in the Huila department that influence the sector. The study concludes with the definition of the map of current managerial competences of organizations in the passionfruit productive sector, and is then contrasted with the map of competences required from these. It also highlights the importance of associativity for small producers, the need to continue conducting research in the sector, and the need to intervene through social outreach projects, so as to generate appropriation and training processes for a set of managerial competencies identified herein, which will strengthen management skills and competitiveness in this type of organization, and ensure, over time, generational change within the sector.

This chapter introduces the problem of “reform capacity” (the ability of political decision-makers to adopt and implement policy changes that benefit society as a whole, by adjusting public policies to changing economic, social, and political circumstances). The chapter also reviews the long-standing discussion in political science about the relationship between political institutions and effective government. Furthermore, the chapter explains why the possibility of compensation matters greatly for the politics of reform; provides a precise definition of the concept of reform capacity; describes the book's general approach to this problem; and discusses the ethics of compensating losers from reform; and presents the book's methodological approach.

AbstractThe standard measure of distance in social networks – average shortest path length – assumes a model of “simple” contagion, in which people only need exposure to influence from one peer to adopt the contagion. However, many social phenomena are “complex” contagions, for which people need exposure to multiple peers before they adopt. Here, we show that the classical measure of path length fails to define network connectedness and node centrality for complex contagions. Centrality measures and seeding strategies based on the classical definition of path length frequently misidentify the network features that are most effective for spreading complex contagions. To address these issues, we derive measures of complex path length and complex centrality, which significantly improve the capacity to identify the network structures and central individuals best suited for spreading complex contagions. We validate our theory using empirical data on the spread of a microfinance program in 43 rural Indian villages.

Computational creativity in built environment (BE) design has been a subject of research interest in the discipline. This paper presents a critical review of various ways computational creativity has been and can be defined and approached in BE design. The paper examines a comprehensive body of contemporary literature on the topics of creativity, computational creativity, and their assessment to identify levels of computational creativity. The paper then proceeds to a further review of the implications of these levels specifically in BE design. The paper identifies four areas in BE design where computational creativity is relevant. In two areas—synthesis (generation) and analysis—there is considerable literature on lower levels of computational creativity. However, in two other areas—interfacing and communication—even the definition of computational creativity is not as defined and clear for the discipline, and most works only consider the role of computers as a supporting tool or medium. These open up future research opportunities for the discipline.

AbstractThe paper studies an extension to nonlinear systems of a recently proposed approach to the definition of modal participation factors. A definition is given for local mode-in-state participation factors for smooth nonlinear autonomous systems. While the definition is general, the resulting measures depend on the assumed uncertainty law governing the system initial condition, as in the linear case. The work follows Hashlamoun et al. (IEEE Trans Autom Control 54(7):1439–1449 2009) in taking a mathematical expectation (or set-theoretic average) of a modal contribution measure over an uncertain set of system initial state. Poincaré linearization is used to replace the nonlinear system with a locally equivalent linear system. It is found that under a symmetry assumption on the distribution of the initial state, the tractable calculation and analytical formula for mode-in-state participation factors found for the linear case persists to the nonlinear setting. This paper is dedicated to the memory of Professor Ali H. Nayfeh.

Abstract This empirical study explores the financialization of social sustainability driven by sustainability accounting and reporting initiatives (SARIs). Since no globally accepted definition of what social sustainability encompasses exists, the paper asks how social sustainability is translated into the financial market language by SARIs as they provide standards for disclosing corporate non-financial performance and promote their concepts of social sustainability. The paper uses a two-step qualitative content analysis. First, it operationalizes social sustainability based on the empirical data of six sustainability rating agencies. Second, this operationalization is compared with the concepts created by three SARIs. The paper shows significant differences between the concepts of the SARIs and the rating agencies. While the rating agencies altogether interpret social sustainability with 83 distinct aspects, the SARIs, although differently created, use significant reduced concepts where 20% of these aspects are absent. The result of this financialization process could be a simplified and financially determined concept of social sustainability within die socially discourse. The research is limited to social sustainability and its financialization by SARIs. Individual indicators and their way or intensity to capture aspects of social sustainability were not part of the research interest. Further research should investigate the economic and the ecological pillars of sustainability as well as the usage of such financialized concepts within the society and especially by corporations. The paper unfolds the arbitrariness of operationalizing a qualitative phenomenon like social sustainability through the financial system. It discloses the need for looking at the mechanisms behind such processes and at the interests of the actors behind the frameworks. The paper reveals the financialization process driven by SARIs and demonstrates its simplifying effects on the concept of social sustainability. Furthermore, the paper shows that SARIs as metrics for non-financial aspects are troubled with a lack of transparency and a lack of convergence.

During the early 20th century, the urban housing supply in Estonia expanded quickly to meet growing housing demand, resulting in tenement districts conceived for maximum profitability of rental units. In Karlova, a district near the city center of Tartu, about five hundred wooden houses, built between 1911 and the early 1920s and displaying simple Art Nouveau details, are set amid a charming district with a distinct milieu. This article focuses on three time periods during which the development of its built environment gave Karlova its distinctiveness: (1) the years leading up to World War I; (2) the interwar period; and (3) the two decades since 1991, or the post-transition period. Although the district was neglected during the Soviet era, it remains remarkably intact and has even experienced, since the 1990s, gentrification. The high-quality housing stock and charming built environment has much to offer to its diverse population of students, professionals, families, and longtime residents. Santrauka Dvidešimtojo amžiaus pradžioje gyvenamųjų namų pasiūla Estijoje greitai augo atitikdama į augančius gyvenamojo ploto poreikius. Minėtos situacijos rezultatas - daugiabučių namų kvartalai sukurti taip, kad iš nuomojamų patalpų būtų gaunamas maksimalus pelnas. Karlova – kvartalas netoli Tartu centro. Jį sudaro apie penki šimtai medinių namų, pastatytų tarp 1911 ir 1920 metų. Pastatams būdingos paprastos Art Nouveauarchitektūrinės detalės, jie pastatyti išskirtinėje patrauklioje aplinkoje. Pateikiamame straipsnyje nagrinėjami trys laikotarpiai, per kuriuos užstatymo kaita aptariamoje teritorijoje sukūrė išskirtinį jos tapatumą: 1) laikotarpis iki Pirmojo pasaulinio karo; 2) tarpukaris; 3) du dešimtmečiai po 1991 m. Nežiūrint to, kad sovietiniais metais teritorija buvo nesaugoma ir ja nesirūpinama, Karlova išsaugojo nepažeistą architektūrinį urbanistinį vientisumą, o po 1990 m. teritorijoje prasidėjo gentrifikacijos procesai. Aukštos kokybės gyvenamasis užstatymas ir žavi urbanistinė aplinka gali daug pasiūlyti įvairioms gyventojų grupėms: studentams, profesionalams, šeimoms ir vyresnio amžiaus žmonėms.

Autobiographical Narrative

The article deals with the life situation of the families of prisoners, in particular, parental relationships connected with the experience of incarceration in a correctional institution. During the realisation of the research I noticed many difficulties in finding contact with potential interlocutors, therefore I considered the families of prisoners as an environment “invisible in the research field”. In addition, I defined families of prisoners as marginalised and stigmatised environments. The main aim of the article is to show selected methodological dilemmas that can be encountered through the design and analysis of biographical research of family members of prisoners. The theoretical introduction of the paper as an extended definition of the penitentiary crisis allowed to characterise the dominant trends and directions of research on prisoners’ families. Further, it focused on selected problems of realisation of qualitative research (especially biographical research). I analyse the literature and present my own methodological approach based on the direction of interpretative sociology. Using the potential of the autobiographical narrative interview technique (of the German sociological school of Fritz Schütze), I collected 31 interviews with adult children of prisoners and 30 interviews with parents of prisoners. Finally, I refer to my own research experience and discuss the “usefulness and ineffectiveness” of an autobiographical narrative interview. Moreover, I characterise key reflections on the role of the researcher in obtaining autobiographical narrations. The article is an invitation to discuss the improvement of research procedures, especially in the area of research on family members of persons in prisons.

<p>In recent years, the use of remote sensed NDVI has become recurrent in urban studies regarding the adaptation of cities to climate change. However, due to the physical diversity within cities and the different resolution offered by the sensors, the territorial interpretation of what the NDVI values really mean becomes difficult. Where the larger the size of the cells of the image, the greater the number of elements of the built environment within it, and the more complex the interpretation becomes.</p><p>In this work, the relationship between the NDVI of three sensors with different cell resolution for the same location and date is studied. In particular, the city of Granollers in the Metropolitan Area of Barcelona is analyzed. First, the NDVI images were obtained from Landsat-8 with 30m resolution, Sentinel-2 with 10m and from the Ministry of Agriculture, Livestock, Fisheries and Food of Catalonia (DARP) with 0.125m resolution. Then, the comparison was performed with a sample of five different typologies of the territory: dense urban core, suburban, industrial, area of highway and rural.</p><p>As first results, a supervised classification of the DARP image allowed the definition of 0.30 as the precise minimum value of NDVI that indicates the actual presence of vegetation. On the other hand, the comparison indicates that, in the urban context, the larger the cell size, the presence of vegetation quality is overestimated, where the higher percentage of cells is concentrated in higher NDVI values than in those with lower resolution. However, this behavior is not appreciated in rural areas, where higher percentages of cells of different resolutions were concentrated in the same NDVI ranges.</p><p>In such a way, it is corroborated that it is in the urban context where this indicator has a greater difficulty of territorial interpretation. Statements that are analyzed in greater depth in this study, where its implications in the use of NDVI in urban studies for the adaptation of cities to climate change are discussed.</p>

Recent research about the theoretical approach to elements of cultural heritage that can be included in the newly born class Underground Built Heritage (UBH), has provided several instruments for the functional classification and the static and dynamic analysis of all artefacts coherent with the given definition, while introducing several criteria for their reuse and the evaluation of connected enhancement processes as well. These guidelines can be adopted to analyze single artefacts, groups of homogenous or heterogeneous elements, and also selected territorial assets or national systems, even at a comparative level. With reference to this potential, research results from the application of this new methodological approach to the outputs of three ongoing projects by the National Research Council of Italy, all focusing on UBH, in three countries: China, Japan and Italy, are presented. With reference to the above-mentioned geographical contests, the research introduces a comparative study focusing on selected examples of artefacts that have been historically built underground to manage three functions: living space, religion and economy. This study, carried out based on data collected during onsite visits by the authors, consists in three steps: selection and analysis of case studies, definition of level of reuses on the basis of a given scale, and analysis of the different tools adopted for their conservation and enhancement. In the conclusions, possible future implementations of reuses of the analyzed elements are pointed out.
