How do people perceive, understand, and anticipate responding to flash flood risks and warnings? Results from a public survey in Boulder, Colorado, USA

This study investigates flash flood forecast and warning communication, interpretation, and decision making, using data from a survey of 418 members of the public in Boulder, Colorado, USA. Respondents to the public survey varied in their perceptions and understandings of flash flood risks in Boulder, and some had misconceptions about flash flood risks, such as the safety of crossing fast-flowing water. About 6% of respondents indicated consistent reversals of US watch-warning alert terminology. However, more in-depth analysis illustrates the multi-dimensional, situationally dependent meanings of flash flood alerts, as well as the importance of evaluating interpretation and use of warning information along with alert terminology. Some public respondents estimated low likelihoods of flash flooding given a flash flood warning; these were associated with lower anticipated likelihood of taking protective action given a warning. Protective action intentions were also lower among respondents who had less trust in flash flood warnings, those who had not made prior preparations for flash flooding, and those who believed themselves to be safer from flash flooding. Additional analysis, using open-ended survey questions about responses to warnings, elucidates the complex, contextual nature of protective decision making during flash flood threats. These findings suggest that warnings can play an important role not only by notifying people that there is a threat and helping motivate people to take protective action, but also by helping people evaluate what actions to take given their situation.

Toward a theory of semantic representation

We present an account of semantic representation that focuses on distinct types of information from which word meanings can be learned. In particular, we argue that there are at least two major types of information from which we learn word meanings. The first is what we call experiential information. This is data derived both from our sensory-motor interactions with the outside world, as well as from our experience of own inner states, particularly our emotions. The second type of information is language-based. In particular, it is derived from the general linguistic context in which words appear. The paper spells out this proposal, summarizes research supporting this view and presents new predictions emerging from this framework.

A new regime of carbon counting: the practices and politics of accounting for everyday carbon through C02e

Inspired by the commercial desires of global brands and retailers to access the lucrative green consumer market, carbon is increasingly being counted and made knowable at the mundane sites of everyday production and consumption, from the carbon footprint of a plastic kitchen fork to that of an online bank account. Despite the challenges of counting and making commensurable the global warming impact of a myriad of biophysical and societal activities, this desire to communicate a product or service's carbon footprint has sparked complicated carbon calculative practices and enrolled actors at literally every node of multi-scaled and vastly complex global supply chains. Against this landscape, this paper critically analyzes the counting practices that create the ‘e’ in ‘CO2e’. It is shown that, central to these practices are a series of tools, models and databases which, in building upon previous work (Eden, 2012 and Star and Griesemer, 1989) we conceptualize here as ‘boundary objects’. By enrolling everyday actors from farmers to consumers, these objects abstract and stabilize greenhouse gas emissions from their messy material and social contexts into units of CO2e which can then be translated along a product's supply chain, thereby establishing a new currency of ‘everyday supply chain carbon’. However, in making all greenhouse gas-related practices commensurable and in enrolling and stabilizing the transfer of information between multiple actors these objects oversee a process of simplification reliant upon, and subject to, a multiplicity of approximations, assumptions, errors, discrepancies and/or omissions. Further the outcomes of these tools are subject to the politicized and commercial agendas of the worlds they attempt to link, with each boundary actor inscribing different meanings to a product's carbon footprint in accordance with their specific subjectivities, commercial desires and epistemic framings. It is therefore shown that how a boundary object transforms greenhouse gas emissions into units of CO2e, is the outcome of distinct ideologies regarding ‘what’ a product's carbon footprint is and how it should be made legible. These politicized decisions, in turn, inform specific reduction activities and ultimately advance distinct, specific and increasingly durable transition pathways to a low carbon society.

An introductory perspective to horticulture: plants for people and places

Horticulture is “the first of all the arts and sciences”. This definition indicates both the breadth and depth of the discipline and its early inception as mankind changed from being hunter-gatherers to cultivators. Intensive crop production which is a form of horticulture preceded more extensive agricultural practices. From that time onwards the intricate involvement of horticulture in man’s life has become very apparent by its multitude of applications and the interests of those involved. These extend from the provision of foodstuffs and nutritional benefits through pharmaceuticals to aspects of rest and relaxation onto encouraging physical and mental well-being. Horticulture is therefore, a discipline with many components and as such that it can mean different things in the varying context of its use. This chapter introduces the meanings of horticulture as expressed by the authors who have contributed to this Trilogy of Books. They have analysed in considerable depth “Horticulture” as expressed in its facets of production, environment and society. Horticulture has impact and expression in each of these fields of human activity. This chapter also sets Horticulture into the wider context of the world of plants and their intensive cultivation both in their use by mankind and in the natural world. The aim is to demonstrate the depth and breadth of human activity associated with this discipline for it stretches from crop production, through landscape design and maintenance and into aspects of society and its expression in the arts and humanities. Horticulture touches almost every aspect of human activity. Increasingly Horticulture has significant importance in contributing towards the mitigation of the major problems which now face life on Earth such as:- climate change, food security, the loss of natural biodiversity, pollution, resource erosion and over-population. Indeed despite or perhaps because of its antiquity and therefore its strong connection between science, technology and practice horticulture can offer solutions that might allude other disciplines.

The role of text in televideo cybersex

Televideo cybersex provides a unique example of the ways meanings are instantiated, identities constructed, and relationships negotiated across different semiotic modes. This article explores the role of verbal messages in these multimodal exchanges, examining the specific interactional functions they perform. Text, it is argued, plays a rather unique role in this particular kind of interaction. Unlike ordinary face-to-face conversation, in which the body (posture, gestures, gaze) usually plays more of an ancillary role, in televideo cybersex, the bodily performance is primary, with verbal messages functioning to contextualize physical actions. Text is used to help increase the sense of ‘presence’ participants feel, to regulate the rhythm of the unfolding interaction, to help manage the orderly exchange of information, and to create narrative frames within which bodily displays can be interpreted and made coherent.

Mediated action and sexual risk: Searching for 'culture' in discourses of homosexuality and AIDS prevention in China

This paper examines the concept of ‘culture’ and its relationship to HIV prevention. Culture is here seen as the interaction between human beings and the various ‘cultural tools’ they appropriate when taking action. Among these tools are ways of speaking which encode certain meanings, ideologies and social practices. When individuals take action with regard to AIDS, what they do is mediated through voices which they borrow strategically from their environ- ment. The textual tools that are available and the ways individuals adapt and combine them work to either limit or amplify their participation in HIV prevention. What are traditionally seen as ‘cultures’ or ‘sub-cultures’, or worse, ‘risk groups’, are, in this perspective, viewed as ‘communities of practice’, groups of individuals who share particular cultural tools and ways of using them. This conceptual framework is applied to recent discourses of homosexuality and AIDS prevention in China. An instance of ‘of� cial’ discourse in the form of an AIDS education pamphlet for ‘gays’ is analysed for the voices it contains and how these voices are strategically marshalled by the authors and mixed with other voices in ways which amplify participation in AIDS prevention for some and limit it for others. This ‘offical’ discourse is then compared to the discourse of homosexually active Chinese men recently interviewed in Beijing and Fuzhou to examine which of these of� cial voices and other voices they appropriate, and how they adapt these voices in responding to HIV.

Representing violence, playing control: warring constructions of masculinity in Action Man toys

This chapter analyses how children, and especially boys, are constructed as ‘savage’ in relation to warlike toys and representations that narrate particular versions of conflict, such as war and terrorism. The chapter uses Action Man toys as a case study that is contextualized against a wider background of other toys, television programmes and films. Action Man is most familiar as a twelve-inch costumed toy figure, but the brand also extends into related media representations such as television programmes, comics and advertising. The chapter focuses increasingly on the specifics of Action Man representations produced from the 1960s to the 1990s, prefacing this detailed discussion with some examples of transmedia texts aimed at children in film and television. This chapter suggests that making the toy a central object of analysis allows for insights into representations of the gendered body that are particularly useful for work on the child-savage analogy. Some of the cultural meanings of war toys, warlike play and representations of war that can be analysed from this perspective include their role in the construction of masculine identity, their representation of particular wars and warlikeness in general, and their relationship to consumer society. This complex of meanings exhibits many of the contradictions that inhabit the construction of ‘the child’ in general, such as that the often extreme masculinity of war toys and games is countered by an aesthetic of spatial disposition, collecting and sometimes nurturing that is more conventionally feminine. Such inter-dependent but apparently opposed meanings can also be seen in the construction of the child as untainted by adult corruption yet also savage, or as in need of adult guidance yet also offering a model of innocence and purity that adults are expected to admire.
