Semilattice-based dualities

The paper discusses regularisation of dualities. A given duality between (concrete) categories, e.g. a variety of algebras and a category of representation spaces, is lifted to a duality between the respective categories of semilattice representations in the category of algebras and the category of spaces. In particular, this gives duality for the regularisation of an irregular variety that has a duality. If the type of the variety includes constants, then the regularisation depends critically on the location or absence of constants within the defining identities. The role of schizophrenic objects is discussed, and a number of applications are given. Among these applications are different forms of regularisation of Priestley, Stone and Pontryagin dualities.     

Birkhoff-like sheaf representation for varieties of lattice expansions

Given a variety we study the existence of a class such that S1 every A can be represented as a global subdirect product with factors in and S2 every non-trivial A is globally indecomposable. We show that the following varieties (and its subvarieties) have a class satisfying properties S1 and S2: p-algebras, distributive double p-algebras of a finite range, semisimple varieties of lattice expansions such that the simple members form a universal class (bounded distributive lattices, De Morgan algebras, etc) and arithmetical varieties in which the finitely subdirectly irreducible algebras form a universal class (f-rings, vector groups, Wajsberg algebras, discriminator varieties, Heyting algebras, etc). As an application we obtain results analogous to that of Nachbin saying that if every chain of prime filters of a bounded distributive lattice has at most length 1, then the lattice is Boolean.We wish to thank Lic. Alfredo Guerin and Dr. Daniel Penazzi for helping us with linguistics aspects. We are indebted to the referee for several helpful suggestions. We also wish to thank Professor Mick Adams for providing us with several reprints and useful e-mail information on the subject.Suported by CONICOR and SECyT (UNC).     

Duality for algebras of relevant logics

This paper defines a category of bounded distributive lattice-ordered grupoids with a left-residual operation that corresponds to a weak system in the family of relevant logics. Algebras corresponding to stronger systems are obtained by adding further postulates. A duality theoey piggy-backed on the Priestley duality theory for distributive lattices is developed for these algebras. The duality theory is then applied in providing characterizations of the dual spaces corresponding to stronger relevant logics.The author gratefully acknowledges the support of the National Sciences and Engineering Research Council of Canada.     

Floorgasm: Queer(s), solidarity and resilience in punk

This article explores queer(ed) punk scenes, primarily in Australia. Queer ciswomen, transwomen and non-binary people aged 20–30 years are the informants here in a feminist-informed ethnographic study. They were found to engage strategies of resistance against cismale dominance at punk gigs and events in order to claim queer(ed) territory. In brief, they worked collectively to subvert the dominant patriarchal norms in punk spaces. They mobilised community-building through the politics of Do-It-Together (DIT) as a radical reshaping of the traditional punk ethos of DIY (Do-It-Yourself). They also worked to make gigs more queer-affirmative through mobilising the initiative of safe(r) spaces. We map some queer collective resilience in punk to authorise the expression of counter-hegemonic gender identities. The gig outcome was pleasurable queer solidarity enmeshed with music, a kind of metaphysical ‘floorgasm’.     

蒯因和伽登佛斯对绿蓝悖论"解决"思路评析

关于绿蓝问题的讨论一直在持续着。逻辑操作路线更为“本质”的方法,即“自然类’他们的思路。蒯因和伽登佛斯寻求的是比纯粹的语言和和“概念空间”的解决方法,本文试评析     

中文文本熟悉性在词切分和词汇识别中的作用

基于E-Z读者模型和中文阅读的整合模型, 词切分和词汇识别是否属于交互作用的统一过程存在争议。通过转换阅读方向来操纵文本熟悉性, 研究其在词切分和词汇识别中的作用。实验1考察中文文本熟悉性和词间空格促进作用之间的权衡。使用Eyelink 1000记录40名大学生在中文阅读中的眼动特征。结果发现：词间空格对中文阅读的促进作用在阅读训练后消失, 表明中文阅读中文本熟悉性和词间空格的促进作用之间存在权衡。实验2操纵文本熟悉性和词频来探究文本熟悉性在词汇识别中的作用, 结果发现：文本熟悉性和词频在早期指标上的交互作用; 阅读训练和词频不存在交互作用, 表明文本熟悉性影响词汇识别的早期加工阶段。研究结果表明中文阅读的词切分和词汇识别可能是顺序加工, 支持E-Z读者模型。     

自我优势效应对远近空间中空间参照框架的影响

联合颜色−标签匹配任务和空间参照框架判断任务,考察自我优势效应对远近空间中空间参照框架表征的影响。颜色−标签匹配任务要求被试对颜色（黑色/白色叉子）与标签词（自我/他人）之间建立稳定的联结,被试随机分为自我联结组和他人联结组,两组被试均需在远近空间中完成空间参照表征任务。结果发现：（1）与他人联结组相比,自我联结组表现出显著的自我优势效应;（2）自我优势效应对空间参照表征的影响仅体现在近处空间且对自我中心表征任务的影响更大。研究表明,自我优势效应优先影响近处空间表征,表现出近处优先性。     

Affect,infrastructure and activism: The House of Brag's London Queer Social Centre in Brixton,South London

The House of Brag was a queer, anti-racist, feminist squatting collective active between 2012 and 2014. This article pieces together an affective and infrastructural geography of the House of Brag's last project: a squatted social centre in Brixton, south London, in the summer of 2014. Drawing on interviews with members of the collective, this article argues that efforts to think and live social and political alternatives – and the affective dimensions of these efforts – cannot be abstracted from their infrastructures. The material space and infrastructure of the squatted social centre, this article contends, shaped the House of Brag's dynamics and work in crucial ways. In foregrounding these issues, this article contributes to literature on geographies of affect, emotions and social movements, in which conflict and ‘negative’ affects and emotions are often minimised, and which largely overlook the complex material geographies of spaces of activism. In exploring a queer, anti-racist, feminist squatted project in 2010s London, this article also contributes to literature on squatting by focusing on a time period, on politics and on locations largely overlooked.
