The Importance of Attention Diversity and How to Measure It

Studies of political attention often focus on attention to a single issue, such as front‐page coverage of the economy. However, examining attention to a single issue without accounting for the agenda as a whole can lead to faulty assumptions. One solution is to consider the diversity of attention; that is, how narrowly or widely attention is distributed across items (e.g., issues on an agenda or, at a lower level, frames in an issue debate). Attention diversity is an important variable in its own right, offering insight into how agendas vary in their accessibility to policy problems and perspectives. Yet despite the importance of attention diversity, we lack a standard for how best to measure it. This paper focuses on the four most commonly used measures: the inverse Herfindahl Index, Shannon's H, and their normalized versions. We discuss the purposes of these measures and compare them through simulations and using three real‐world datasets. We conclude that both Shannon's H and its normalized form are better measures, minimizing the danger of spurious findings that could result from the less sensitive Herfindahl measures. The choice between the Shannon's H measures should be made based on whether variance in the total number of possible items (e.g., issues) is meaningful.     

Soweto nights: making black queer space in post-apartheid South Africa

In this article, I examine black queer nightlife in Soweto and its relationship with the making of black queer space in South Africa. Through an in-depth examination of the microgeographies of a Soweto stokvel party, I reveal the complexities of post-apartheid formations of race, class, gender, and sexuality. Employing the idea of usable space, I highlight quotidian practices of leisure as an important site for understanding cultural creativity within the marginalized spaces occupied by black South African queers. Performance and performativity are central to organizing nightlife spaces and reveal both the possibilities and limits encountered by black queers as they try to construct livable lives.     

‘It is where blokes can be blokes’: making places in a New Zealand rugby club

Using the case study of a New Zealand rugby club, in this article, we highlight the role of gender and performance in place attachment. We discuss various performances that contribute to achieving a sense of attachment of club members to the (imagined) community of the rugby club and the different physical spaces of its home ground. Even though performances are played out and read against the backdrop of a popular discourse of New Zealand rugby masculinity, we did not observe characteristics of stereotypical ‘rugby masculinity’ in all rugby places, nor were performances the same throughout one day. Instead, variations were found depending on whether performance was ‘front stage’ or ‘backstage’.     

“The play is set in the theatre”: Conor McPherson and the late-modern humanism of the theatrical event

The plays of Conor McPherson emphasise a sociality of story, language, and theatre. His theatre demands both that a storyteller be heard and that storytellers acknowledge the reality of their words existing in a social space. Meaning-making in McPherson's monologues must thus be social, shared either between the monologists and the theatrical audience, or between a storyteller and the in-play audience. This essay argues that the dynamic of storytelling in McPherson's theatre epitomises a late-modern humanist pursuit. We encounter his characters on loosely defined linguistic journeys of ontological becoming, and are called upon as audience to become interlocutors, supporting and advancing this humanist process. Ultimately, McPherson's work suggests that dramatic characters and theatrical audience exist in a reciprocal relationship of soliciting and supporting a becoming from one another.     

The Materiality of Social Power: The Artifact-Acquisition Perspective

This paper explores the materiality of social power relationally through study of social interactions with artifacts. Specifically, it is argued that acquisition of an artifact instantiates social power by imposing interactions on groups taking part in that artifact's life-history activities. We introduce the “performance-preference matrix,” an analytic tool for systematically studying the effects of such acquisition events on activity groups. The use of the performance-preference matrix is illustrated through an example: the acquisition of electric-arc lights for lighthouses in the 19th century. Suggestions are offered for analyzing culture-contact situations and for handling singularized artifacts such as heirlooms and monuments.

Capillary Active Interior Insulation Systems for Wall Retrofitting: A More Nuanced Story

To thermally upgrade exterior masonry walls, interior insulation is often the only possible retrofitting technique, especially when dealing with historic buildings. Unfortunately, it is also the riskiest post-insulation technique, as frost damage, interstitial condensation, and other damage patterns might be induced. To diminish those risks, nowadays so-called capillary active interior insulation systems are often promoted. These systems aim a minimal reduction of the inward drying potential, while interstitial condensation is buffered.

Currently, several capillary active systems are on sale. These different types have, however, widely varying properties. In this article, a closer look at the hygrothermal properties and the working principle of a number of “capillary active” interior insulation systems is made. The spread in capillary absorption coefficients and the vapor diffusion resistances of the different systems is discussed and their influence is illustrated. Based on all this, a more nuanced view on capillary active insulation systems is pursued.

Morphological study of the ancient dogs from three neolithic sites in China

Ancient Chinese dogs excavated at three archaeological sites and stored in the Institute of Vertebrate Paleontology and Paleoanthropology, Academia Sinica, were the object of this study (Xiawanggang site, 5000–6000 years BP; Keshengzhuang site, 3000–4000 years BP; Shangsunjia site, Bronze age). During these periods, there were large morphological variations in Chinese dogs beyond a single dog class, as with Jomon dogs. Dogs with a large ‘stop’ were already present in China but not in Japan. At the Keshengzhuang site, middle to large class dogs were also excavated. At least three types were confirmed within these dogs. In the aged dog in Xiawanggang, antemortem loss of many teeth was observed suggesting active use of the teeth and it is possible that this dog was used for hunting as were the Japanese Jomon dogs. © 1998 John Wiley & Sons, Ltd.
