The good process or the great illusion? A spatial perspective on public participation in Danish municipal wind turbine planning
2021
This paper explores the nature of public participation in Danish municipal wind power planning. Although the procedure for involving citizens embedded in the environmental impact assessment (EIA) procedure for wind power projects is often praised for its participatory character, the approach is not without problems. In this paper, we identify the limitations and potentials of the public space provided for citizen involvement. By means of Gaventa’s terminology suggesting a continuum of public spaces for participation, the paper shows how the planning process can be approached from different spatial perspectives – each of them illuminating different forms of power, resistance and opportunitie…
Singular quasisymmetric mappings in dimensions two and greater
2018
For all $n \geq 2$, we construct a metric space $(X,d)$ and a quasisymmetric mapping $f\colon [0,1]^n \rightarrow X$ with the property that $f^{-1}$ is not absolutely continuous with respect to the Hausdorff $n$-measure on $X$. That is, there exists a Borel set $E \subset [0,1]^n$ with Lebesgue measure $|E|>0$ such that $f(E)$ has Hausdorff $n$-measure zero. The construction may be carried out so that $X$ has finite Hausdorff $n$-measure and $|E|$ is arbitrarily close to 1, or so that $|E| = 1$. This gives a negative answer to a question of Heinonen and Semmes.
Structural analysis of Borrelia burgdorferi periplasmic lipoprotein BB0365 involved in Lyme disease infection.
2019
The periplasmic lipoprotein BB0365 of the Lyme disease agent Borrelia burgdorferi is expressed throughout mammalian infection and is essential for all phases of Lyme disease infection; its function, however, remains unknown. In the current study, our structural analysis of BB0365 revealed the same structural fold as that found in the NqrC and RnfG subunits of the NADH:quinone and ferredoxin:NAD+ sodium-translocating oxidoreductase complexes, which points to a potential role for BB0365 as a component of the sodium pump. Additionally, BB0365 coordinated Zn2+ by the His51, His55, His140 residues, and the Zn2+ -binding site indicates that BB0365 could act as a potential metalloenzyme; therefore…
Intestinal Spirochetes of Termites
2010
Spirochetes differ from all other bacteria by their unique morphology and mechanism of motility. The cells possess a helical shape, and the flagella (axial filaments) are located in the periplasmic space. The flagella are attached to the cell poles and wrapped around the protoplasmic cylinder. The flagella and the protoplasmic cylinder are surrounded by a multilayered outer sheath or outer cell envelope (Canale-Parola, 1984). The 16S rRNA sequences demonstrated that the spirochetes represent a monophyletic phylum within the bacteria (Paster and Dewhirst, 2001).
Graphical metric space: a generalized setting in fixed point theory
2016
Building on recent ideas of Jachymski, we work on the notion of graphical metric space and prove an analogous result for the contraction mapping principle. In particular, the triangular inequality is replaced by a weaker one, which is satisfied by only those points which are situated on some path included in the graphical structure associated with the space. Some consequences, examples and an application to integral equations are presented to confirm the significance and unifying power of obtained generalizations.
Spazio pubblico vs. spazio privato: nuovi modelli e regole “contemporanee”. Un caso studio a Palermo
2022
L’emergenza pandemica degli ultimi due anni ha comportato, tra l’altro, la necessità di ripensare la funzione di alcuni spazi pubblici che tradizional- mente servivano per attività di socializzazione. Lo spazio rappresenta peraltro una dimensione crucia- le nella costruzione delle politiche di prevenzione, gestione e contrasto alla diffusione del virus. Con l’obiettivo di costruire un approccio integrato a quegli spazi pubblici e privati che possono essere ridisegnati per i bisogni di piccole comunità, il presente paper, partendo da esperienze di ricerca-azione integrate con l’attività didattica, vuole ragionare su una particolare tipologia di spazio pubblico, quella relativa agli spazi…
Shopping malls as pseudo-public spaces. The shopping mall as an emergent public space in Palermo
2012
Much has been written on the role of public space in contemporary societies, and many scholars agree that public space today is a controversial and arguably critical concept. It may actually seem that even the basic idea of what is or should be ‘public’ is experiencing a deep and troublesome reconsideration, as new forms of privatization slowly but firmly erode its fundaments. Within this conceptual framework, this paper aims at critically analyzing the idea of public space today, with particular attention to the idea of public space as a shopping mall. Characteristics of the Italian way of using shopping malls, and their social and spatial consequences, are investigated and analyzed throug…
IL PROGETTO CONTEMPORANEO DEGLI SPAZI PUBBLICI AD ALCAMO
2021
Il saggio presenta alcuni progetti significativi nella città di Alcamo, in cui il tema dello spazio pubblico si presenta come una sorta di allestimento, che configura luoghi di qualità per la città contemporanea. Questi interventi manifestano la loro partecipazione a quello spirito contemporaneo che elabora l’architettura come sistema di relazioni spaziali e temporali: ricostruendo un ordine tra le cose – i pieni ed i vuoti, la vegetazione e le pietre, la città e il paesaggio – e un legame evidente tra contemporaneità e tradizione.
Caleidoscopico Mercato Ballarò: ampio spazio alla ricerca-azione a Palermo
2019
The proposal to trigger regenerative processes in the urban and social fabric in an unstable context is the foundation of this research-action developed with a systemic approach, first observing the environment built in its entirety and subsequently overcoming the limited concept of interventions, over time and in space, through three priority criteria: resilience, adaptability and transformability. These criteria activate a design strategy in complex systems to respond to situations of environmental, social and economic instability. A double tension guides this research in the field through continuous operations of distancing4 and interaction with institutions, associations, marketers and …
Challenging or Accommodating the Football System? A Case Study of Female Football Supporter Communities in Spain
2018
The chapter is dedicated to the study of a specific type of football community that emerged during the 1980s in Spain: women’s penas. Llopis-Goig and Flores discuss how women’s link to these penas provides them with networks of support and sociability, bonds of friendship and integration in a community as well as a door to the public space that helps them avoid the isolation of a nuclear family for some women. Thus, the female fans generate empowerment strategies that allow them to gradually combat the discrimination experienced in football and in society. However, Llopis-Goig and Flores argue that women’s penas cannot be regarded as initiatives that question the patriarchal structure of fo…
