Self-help housing in urban Colombia; alternatives for the production and distribution of building materials

Building materials account for a high percentage of the non-land cost of self-help housing. Few studies, however, have examined the use of building materials by self-help builders and the practicalities of producing and distributing the materials in an alternative manner. This paper discusses the nature of construction by self-help in the intermediate-sized Colombian city of Pereira, focusing in particular on the building materials used, and examines various attempts to reduce the cost of building-materials for self-help builders. It is concluded that projects which aim to introduce alternative building materials or retail outlets for self-help builders, need to consider the nature of construction by self-help and the operation of the building-materials market, if they are to have any chance of success.     

Alcohol abuse as a rite of passage: the effect of beliefs about alcohol and the college experience on undergraduates' drinking behaviors

Qualitative studies of alcohol's ritual influences indicate that college undergraduates who drink heavily tend to view alcohol use as integral to the student role and feel entitled to drink irresponsibly. Our analyses, based on a standardized measure of these beliefs administered to approximately 300 students, confirmed these findings. Among our sample, beliefs about alcohol and the college experience had an effect on levels of alcohol consumption similar in magnitude to that of other variables commonly associated with a risk for heavy drinking. Moreover, the alcohol beliefs index moderated the effects of three risk factors--gender, high school drinking, and friends' use of alcohol--on respondents' drinking behaviors. These findings are discussed within the context of the anthropological literature on liminality and rites of passage and with regard to strategies for intervention that address the structural roots of the widespread abuse of alcohol on college campuses.     

The Evolving Field of Risk Communication

The 40th Anniversary of the Society for Risk Analysis presents an apt time to step back and review the field of risk communication. In this review, we first evaluate recent debates over the field's current state and future directions. Our takeaway is that efforts to settle on a single, generic version of what constitutes risk communication will be less productive than an open-minded exploration of the multiple forms that comprise today's vibrant interdisciplinary field. We then review a selection of prominent cognitive, cultural, and social risk communication scholarship appearing in the published literature since 2010. Studies on trust in risk communication messengers continued to figure prominently, while new research directions emerged on the opportunities and critical challenges of enhancing transparency and using social media. Research on message attributes explored how conceptual insights particularly relating to framing, affective and emotional responses, and uncertainty might be operationalized to improve message effectiveness. Studies consistently demonstrated the importance of evaluation and how varying single attributes alone is unlikely to achieve desired results. Research on risk communication audiences advanced on risk perception and multiway engagement with notable interest in personal factors such as gender, race, age, and political orientation. We conclude by arguing that the field's interdisciplinary tradition should be further nurtured to drive the next evolutionary phase of risk communication research.     

360 Video: A prototyping process for developing virtual reality interventions

Abstract

Virtual reality (VR) has emerged as a promising technological intervention for anxiety disorders. However, there are no existing standards and best practices to evaluate the effectiveness of environments to achieve their intervention goals. The purpose of this study was to develop a VR intervention for student veterans with social anxiety disorder and test feasibility utilizing a three-stage development model. The development of a therapeutic VR environment may benefit from an interdisciplinary collaboration of researchers from various fields of study. Utilizing three stages of prototyping with two virtual reality platforms, fully immersive video (n?=?6) and three-dimensional (3-D) immersive virtual reality (n?=?8), the research team designed an intervention for student veterans with social anxiety disorder, testing bio-reactivity of participants. Results of prototyping include user feedback validating increased stress levels and increased bio-reactivity specifically in galvanic skin response and heart rate elevation. Implications include the use of 360° video for prototyping 3-D virtual reality interventions.     

School choice's idealized premises and unfulfilled promises: How school markets simulate options,encourage decoupling and deception,and deepen disadvantages

In school choice systems, families choose among publicly funded schools, and schools compete for students and resources. Using neoinstitutionalist and relational inequality theories, our article reinterprets recent critical sociological and education research to show how such markets involve actors' enacting myths; these beliefs and their associated practices normalized white, privileged consumption as a basis for revamping public education as market exchanges between schools and families. Proponents argue that choice empowers individuals, focuses organizations on improving quality, and benefits society more broadly by reducing inequality and segregation. We argue that such school choice myths' excessive emphases on individual decision‐making and provider performance obscure the actual impacts of school choice systems upon people, organizations, and society. First, rather than enlarging alternatives that families can easily research, select, and (if needed) exit, school choice systems often simulate options, especially for disadvantaged populations. Second, rather than focusing schools' efforts on performance, innovation, and accountability, they can encourage organizational decoupling, homogeneity, and deception. Third, rather than reducing societal harms, they can deepen inequalities and alienation. Future research should examine both how markets are animated by bounded relationality—routines that enable them to form, maintain, and complete exchanges with organizations—and how activism can challenge marketization.

The household inventory as urban ‘theatre’ in late medieval Burgundy

In 1413 at the death of his wife Guillemot, Jean Aubert, a group of witnesses and a clerk of the local mayoralty met to value the possessions of their residence, resulting in an inventory full of notes and values on rooms and their objects. Within the existing historiography of the Burgundian Netherlands and its northern European neighbours, inventories and their objects tend to be analysed from two perspectives: the Burgundian court and the ‘consumer revolution’. Applying insights from Erving Goffman and Bruno Latour, this article suggests a third perspective should have priority: the urban ‘theatre’ within which objects were documented and placed. Therefore it sets up an alternate methodology which begins with the inventory to build a picture of the theatre (the urban context and residence), the actors (the Aubert family) and the audience (the witnesses of the inventory) to establish new insights into the operation of Burgundian power and the dynamics of the ‘consumer revolution’.
