Lessons learned from a pan-European study of large housing estates : origin, trajectories of change and future prospects
Full text linkThe research leading to this work has received funding from the European Union’s Horizon 2020 research and innovation programme under Marie Skłodowska-Curie grant agreement number 655601. Support also came from three grants from the Estonian Research Council: Institutional Research Grant IUT2-17 on Spatial Population Mobility and Geographical Changes in Urban Regions, Infotechnological Mobility Observatory, and RITA-Ränne. The European Research Council funded this research under the European Union’s Seventh Framework Programme (FP/2007-2013)/ERC [Grant Agreement No. 615159] (ERC Consolidator Grant DEPRIVEDHOODS, Socio-spatial inequality, deprived neighbourhoods, and neighbourhood effects).Mid-twentieth-century large housing estates, which can be found all over Europe, were once seen as modernist urban and social utopias that would solve a variety of urban problems. Since their construction, many large housing estates have become poverty concentrating neighbourhoods, often with large shares of immigrants. In Northern and Western Europe, an overlap of ethnic, social and spatial disadvantages have formed as ethnic minorities, often living on low incomes, settle in the most affordable segments of the housing market. The aim of this introductory chapter is to synthesise empirical evidence about the changing fortunes of large housing estates in Europe. The evidence comes from 14 cities—Athens, Berlin, Birmingham, Brussels, Budapest, Bucharest, Helsinki, Madrid, Milan, Paris, Moscow, Prague, Stockholm and Tallinn—and is synthesised into 10 takeaway messages. Findings suggest that large housing estates are now seen as more attractive in Eastern Europe than in Western Europe. The chapter also provides a diverse set of visions and concrete intervention measures that may help to improve the fortunes of large housing estates and their residents
Highly Structured Multiplication & The Miller Spectral Sequence
Full text linkUniversity of Minnesota Ph.D. dissertation. August 2019. Major: Mathematics. Advisor: Tyler Lawson. 1 computer file (PDF); iv, 114 pages.We examine the Miller spectral sequence for determining the mod-p homology of a connective spectrum X from the mod-p homology of its associated infinite loop space, Ω∞X, considered as an algebra over the mod-p Dyer-Lashof algebra. For each prime p, we give a Koszul complex for computing the E2 page of this spectral sequence, recovering a result of Miller (at p = 2) [35] and Kraines and Lada (at odd primes) [22]. As applications, we determine H∗(HZ; Fp) and H∗(HFp; Fp) at all primes, recovering well-known results. As an original application of the Miller spectral sequence, we study the relationship between H∗(Ω∞X; Fp) and H∗(X; Fp) when X is an E∞-ring spectrum. We show that the Miller spectral sequence can be used to detect nonzero “multiplicative” k-invariants of X at all primes. We also prove that for any integer n ≥ 1, the underlying spectrum of a commutative HFp-algebra R is equivalent to its strict unit spectrum, sl1(R), in a range that is wider than the stable range: [n, pn − 1]. This is a special case of a conjecture by Mathew and Stojanoska [29].Hess, Daniel. (2019). Highly Structured Multiplication & The Miller Spectral Sequence.

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
After/Lives:Insights from the COVID-19 Pandemic for Gay Neighborhoods
No full textBeginning in 2020, COVID-19 produced shock-shifts that were felt acrossthe globe, not least at the level of the local neighborhood. Some of these shifts havecalled into question the role of physical places for face-to-face gatherings, includingthose used by LGBTQ+ people. Such open questions are a key concern for a book ongayborhoods, so this chapter engages in three analytic tasks to provide preliminaryreflections on how pandemics problematize places. While acknowledging a range ofthreats and challenges that the pandemic poses to the future of LGBTQ+ spaces, thischapter focuses on the potential opportunities and unexpected benefits that COVID19 can create, running counter to more pessimistic predictions that abound in populardiscourse. First, the chapter contextualizes how the COVID-19 pandemic is reminiscent of the HIV/AIDS pandemic, allowing the gayborhood to be well-equippedto respond with grassroots activism, particularly in the face of government inactionor apathy. Second, the chapter explores trends that can ensure the future vitality ofLGBTQ+ spaces, including (i) the potential of mutual aid networks, (ii) the power ofinstitutional anchors in LGBTQ+ placemaking efforts, (iii) urban changes related tohomesteading and population shifts, (iv) innovations in the interior design of physical spaces, and (v) opportunities to enhance social connections through augmentedvirtual engagements. Far from signaling the death knell of LGBTQ+ spaces, these trends demonstrate the enduring appeal provided by neighborhoods and communities. Third, the cognitive schemas of lockdowns, re-closeting, and digitalscapesare identified as unique expressions of the shifting spatialities of sexuality in postpandemic urban space. The chapter concludes by arguing that place will still matterfor LGBTQ+ people in a post-COVID-19 era, albeit with altered meanings and material expressions. The socio-spatial consequences of the novel coronavirus will be aconfluence of positive and negative developments, and while some will be reversedas soon as an effective vaccine is found, others will linger indelibly in bodies and thebuilt environment for years to come.<br/
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
