Exploring the set-theoretical structure of objects by additive trees

Arrangements of feature sets that have been proposed to represent qualitative and quantitative variation among objects are shown to generate identical sets of set-symmetric distances. The set-symmetric distances for these feature arrangements can be represented by path lengths in an additive linear tree. Imperfect versions of these feature arrangements are proposed, which also are indistinguishable by the set-symmetric distance model. The distances for the imperfect versions can be represented by path lengths in an additive imperfectly linear tree. When dissimilarities are defined by the more general contrast model and a constant may be added to proximity data, then for both the perfect and imperfect arrangements an additive tree analysis obtains a perfect fit with an imperfectly linear tree. However, in the case of the contrast model also the distinction between the perfect and imperfect arrangements disappears in that also for the perfect arrangements the resulting tree need no longer be linear.The author is grateful to Mathieu Koppen for detailed comments on an earlier version of this article.     

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’.     

越近越诱惑？感知食物空间距离对消费欲望的影响

探讨消费欲望的影响因素及影响机制对解决个体非健康饮食问题具有重要意义。采用2个实验考察感知食物空间距离是否及如何影响消费欲望,以及感知资源口腔占用是否会降低感知空间距离对消费欲望的影响。结果发现：（1）感知空间距离越近,消费欲望越强;（2）感知空间距离通过心理模拟影响消费欲望;（3）占用感知资源口腔会阻碍心理模拟从而降低感知食物空间距离对消费欲望的影响。因此,操纵食物的感知空间距离会通过心理模拟影响个体的消费欲望。     

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     

Local Solidarity

In this article I am particularly interested in the question of solidarity within the boundaries of one's own country. I discuss a qualified beneficence requirement, which claims that we ought to prevent something very bad from happening if it is in our power and if we can do it without sacrificing anything morally significant. I also discuss a fair-share principle, according to which, in Liam B. Murphy's version, "the sacrifice each agent is required to make is limited to the level of sacrifice that would be optimal if the situation were one of full compliance". I argue that the qualified beneficence requirement is reasonable only in the proximity of the one who needs help. When there is no proximity we ought to be guided by a fair-share principle. I also argue that there is an intimate relation between the fair-share principle and the welfare-state ideology.     

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.
