Lie symmetries and superintegrability
No full textWe show that a known superintegrable system in two-dimensional real Euclidean space (Post and Winternitz 2011 J. Phys. A: Math. Theor. 44 162001) can be transformed into a linear third-order equation: consequently we construct many autonomous integrals—polynomials up to order 18—for the same system. The reduction method and the connection between Lie symmetries and Jacobi last multiplier are used
Diasporas and democratization in the post-communist world
No full textIf diaspora communities are socialized with democratic values in Western societies, they could be expected to be sympathetic to the democratization of their home countries. However, there is a high degree of variation in their behavior. Contrary to the predominant understanding in the literature that diasporas act in exclusively nationalist ways, this article argues that they do engage with the democratization of their home countries. Various challenges to the sovereignty of their homelands explain whether diasporas involve with procedural or liberal aspects of democratization. Drawing evidence from the activities of the Ukrainian, Serbian, Albanian and Armenian diasporas after the end of communism, I argue that unless diasporas are linked to home countries that enjoy both international legal and domestic sovereignty, they will involve only with procedural aspects of democratization. Diasporas filter international pressure to democratize post-communist societies by utilizing democratic procedures to advance unresolved nationalist goals

Synthesis and post-polymerisation functionalisation of aliphatic poly(carbonate)s
No full textThis work describes the controlled organocatalytic ring-opening
polymerisation (ROP) of cyclic carbonates with pendant groups for the
preparation of functional aliphatic poly(carbonate)s and poly(estercarbonate)
s. Their subsequent post-polymerisation functionalisations were
studied yielding a range of functional aliphatic poly(carbonate)s.
Chapter 1 reviews the preparation of cyclic carbonates with pendant
functionalities, their ring-opening polymerisation and the postpolymerisation
modifications of the resulting poly(carbonate)s. The properties
and some applications of functional poly(carbonate)s are also discussed.
Chapter 2, 3 and 4 describe the controlled ring-opening polymerisation of
allyl- functional cyclic carbonate MAC (5-Methyl-5-allyloxycarbonyl-1,3-
dioxan-2-one) and propargyl- functional cyclic carbonate MPC (5-Methyl-5-
propargyloxycarbonyl-1,3-dioxan-2-one) using organic catalysts. Successful
functionalisation of allyl-functional poly(carbonate)s was achieved via radical
addition of thiol-containing molecules to the pendant allyl esters (Chapter 2),
while functionalisation of propargyl-functional poly(carbonate)s was realised
via the Huisgen 1,3-dipolar cycloaddition of azides to the pendant propargyl
groups (Chapter 3). In addition, the copolymerisation of MAC and MPC and
the subsequent orthogonal functionalisation of a copolymer was investigated
(Chapter 4). Chapter 5 describes the copolymerisation of MAC (and MPC)
with stereopure lactide, with resulting copolymers with opposite chiralities
being succesfully applied in stereocomplexation.
Chapters 6 summarises the results obtained in Chapters 2, 3, 4 and 5 whilst
Chapter 7 provides the experimental methodologies
Reconsidering 20th Century (post)Industrial Landscapes as Heritage and Resources
No full textThis chapter critically explores the complex legacy of 20th-century industrialisation and deindustrialisation processes, addressing challenges and opportunities in (post)industrial landscapes and heritage conservation. It examines the multifaceted nature of (post)industrial landscapes, which embody both tangible and intangible elements. These landscapes, marked by the interplay of memory and transformation, demand a conscious and respectful reuse and the fostering of sustainable development and community engagement. By suggesting the employment of interdisciplinary methodologies and embracing change as an opportunity, the author highlights the need for active dialogue among academic, institutional, and local actors to preserve and reinterpret these evolving cultural assets
Sounding out the South: S-Town and the challenges of aural representation
No full textAuthor: Ella Waldmann Université de Paris–LARCA Download PDF version In March 2017, the podcast S-Town broke records by reaching ten million downloads four days after its release (Spangler 2017). Created by two producers of the hit programs Serial and This American Life, the podcast instantly attracted critical attention and set off intense debates. Three years later, with over 90 million downloads, S-Town has definitely established itself as a major cultural phenomenon. But the reasons..
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Beth Ditto and the Post-Feminist Masquerade; or How ‘Post’ can Post-Punk Be?
No full textThis article explores the elaboration of a post-punk and queer performativity by US indie group Gossip. In particular, it elaborates on Angela McRobbie’s concept of ‘post-feminist masquerade’ in relation to the group’s frontwoman, Beth Ditto. The group has from the start claimed affiliation to the punk underground and in particular to 1990s “riot grrrls”, a movement of women’s punk bands who entwined punk strategies of reversal in clothing and musical codes with a feminist awareness of the need for women performers to rewrite accepted notions of female performativity and musicianship. Ditto in particular has engaged in a dialogic relationship with the punk legacy of riot grrrls via her femme persona and her fat-affirmative statements. Engaging with post-feminist landscapes of femininity, from nude photo shoots to advice columns on G2, Ditto’s public image works as an ‘alternative’ rendition of the complex legacy of feminist struggles for public representation interpreted through the representational strategies of punk; at the same time, Gossip also engage in a refashioning of the language of women’s punk in a post-feminist era
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Post-modification of organoiron poly(alkynyl methacrylate)s with dicobalt hexacarbonyl
No full textRadical polymerization of organoiron (alkynyl methacrylate)s afforded a series of organoiron poly(alkynyl methacrylate)s with the ability to coordinate dicobalt hexacarbonyl. The polymers were post-modified with dicobalt hexacarbonyl moieties through reaction with dicobaltoctacarbonyl. Gel permeation chromatography indicated that the polymers possessed weight average molecular weights between 17 800 Da and 33 900 Da with PDIs between 1.3 and 1.6. Thermal analysis revealed that the polymers possess glass transition temperatures between 78 and 138 °C
