Heterotopias of mental health care: The role of space in experiences of distress, madness and mental health service use.

The change from an institutional to community care model of mental health services can be seen as a fundamental spatial change in the lives of service users (Payne, 1999; Symonds & Kelly, 1998; Wolch & Philo, 2000). It has been argued that little attention has been paid to the experience of the specific sites of mental health care, due to a utopic (idealised and placeless) idea of ‘community’ present in ‘community care’ (Symonds, 1998). This project hence explored the role of space in service users’ experiences, both of mental health care, and community living. Seventeen ‘spatial interviews’ with service users, utilising participatory mapping techniques (Gould & White, 1974; Herlihy & Knapp, 2003; Pain & Francis, 2003), plus seven, already published first person narratives of distress (Hornstein, 2009), were analysed using thematic analysis (Braun & Clarke, 2006). Mental health service sites are argued to have been described as heterotopias (Foucault, 1986a) of a ‘control society’ (Deleuze, 1992), dominated by observation and the administration of risk (Rose, 1998a), which can in turn be seen to make visible (Hetherington, 2011) to service users a passive and stigmatised subject position (Scheff, 1974; 1999). Such visible positioning can be seen to ‘modulate’ (Deleuze, 1992) participants’ experiences in mainstream space. The management of space has hence been argued to be a central issue in the production and management of distress and madness in the community, both in terms of a differential experience of spaces as ‘concordant’ or ‘discordant’ with distress, and with movement through space being described as a key mediator of experiences of distress. It is argued that this consideration of space has profound implications for the ‘social inclusion’ agenda (Spandler, 2007; Wallcraft, 2001).

Performance of state space and ARIMA models for consumer retail sales forecasting

Forecasting future sales is one of the most important issues that is beyond all strategic and planning decisions in effective operations of retail businesses. For profitable retail businesses, accurate demand forecasting is crucial in organizing and planning production, purchasing, transportation and labor force. Retail sales series belong to a special type of time series that typically contain trend and seasonal patterns, presenting challenges in developing effective forecasting models. This work compares the forecasting performance of state space models and ARIMA models. The forecasting performance is demonstrated through a case study of retail sales of five different categories of women footwear: Boots, Booties, Flats, Sandals and Shoes. On both methodologies the model with the minimum value of Akaike's Information Criteria for the in-sample period was selected from all admissible models for further evaluation in the out-of-sample. Both one-step and multiple-step forecasts were produced. The results show that when an automatic algorithm the overall out-of-sample forecasting performance of state space and ARIMA models evaluated via RMSE, MAE and MAPE is quite similar on both one-step and multi-step forecasts. We also conclude that state space and ARIMA produce coverage probabilities that are close to the nominal rates for both one-step and multi-step forecasts.

Créer ou produire un jeu vidéo? Étude ethnographique d’un milieu de production vidéoludique montréalais

Le jeu vidéo est un produit qui ne cesse de gagner en popularité alors que les expériences ludiques tendent de plus en plus à se diversifier. Les recherches académiques sur l’objet vidéoludique se sont multipliées dans les dernières années afin de comprendre les particularités du nouveau média, surtout en ce qui concerne l’analyse du produit lui-même et sa réception, mais laissant peu de place à sa créa-tion et sa production. Montréal est un lieu idéal pour étudier le médium : en peu de temps, l’industrie du jeu vidéo est devenue l’un des fleurons industriels québécois. La présente étude s’est intéressée aux développeurs de Montréal, ville où se situe la plus grande partie des studios au Québec, afin de connaître leur perception du produit vidéoludique et de l’industrie. Au travers d’une perspective phénoménologique, un séjour ethno-graphique a été effectué dans un studio de production vidéoludique où plusieurs développeurs ont été observés et interviewés. Ce travail s’inscrit dans une anthropologie du travail et rend compte de la com-plexité qui émerge lorsqu’un travail essentiellement créatif vient se heurter à des motifs de production strictes. Plus encore, il rend compte d’un paradigme opposant directement la création et la production dans un milieu qui se présente comme une avenue prometteuse pour une jeunesse désirant vivre d’un travail créatif. Cette condition est attribuable à la nature du jeu vidéo lui-même qui se situe, selon Kline, Dyer-Witheford et De Peuter (2003), à mi-chemin entre la culture, la technologie et les visées commerciales (marketing). Les développeurs se trouvent donc entre deux eaux : d’un côté ils sont influencés par la culture du jeu, relevant de leurs pratiques, leurs préférences et des commu-nautés de développeurs et, de l’autre côté, par l’industrie qui dicte les façons de faire et viennent selon eux minimiser leur potentiel créatif.

La production de thiols biogéniques par les microorganismes aquatiques

Les thiols à faible masse moléculaire (FMM) peuvent affecter la biodisponibilité du mercure et mener à une plus grande production de méthylmercure par les microorganismes méthylants. Les résultats d’une étude réalisée au sein de la matrice extracellulaire du périphyton de la zone littorale d’un lac des Laurentides ont démontré que les concentrations en thiols à FMM retrouvées dans cette matrice sont jusqu’à 1000 fois supérieures à celles de la colonne d’eau avoisinante. Ces thiols sont significativement corrélés à la chlorophylle a du périphyton, suggérant une production par les algues. Le mercure de la matrice extracellulaire, plus spécifiquement dans la fraction colloïdale mobile, est aussi corrélé aux thiols d’origine algale. Ces résultats suggèrent qu’une accumulation de thiols s’opère dans l’espace extracellulaire du périphyton et qu’ils peuvent favoriser le transfert du mercure vers les microorganismes produisant le méthylmercure. Les résultats d’une seconde étude menée sur les méthodes de préservation d’échantillons d’eau pour la conservation des thiols à FMM ont démontré que la température optimale d’entreposage était de -80 °C et que la lyophilisation menait à une sous-estimation des concentrations mesurées. Les taux de dégradation étaient plus rapides lors de la conservation à -20 °C et variables selon la chimie de l’eau utilisée et les espèces de thiols observées. Suivant ces résultats, nous proposons un cadre de recherche pour de futures études sur la spéciation du mercure dans le périphyton et nous suggérons des précautions lors de la manipulation et de la conservation des thiols à FMM d’échantillons naturels.

Planning Urban Food Production into Today's Cities

If cities are to become more sustainable and resilient to change it is likely that they will have to engage with food at increasingly localised levels, in order to reduce their dependency on global systems. With 87 percent of people in developed regions estimated to be living in cities by 2050 it can be assumed that the majority of this localised production will occur in and around cities. As part of a 12 month engagement, Queen’s University Belfast designed and implemented an elevated aquaponic food system spanning the top internal floor and exterior roof space of a disused mill in Manchester, England. The experimental aquaponic system was developed to explore the possibilities and difficulties associated with integrating food production with existing buildings. This paper utilises empirical research regarding crop growth from the elevated aquaponic system and extrapolates the findings across a whole city. The resulting research enables the agricultural productive capacity of today’s cities to be estimated and a framework of implementation to be proposed.

An overview of Earth's global electric circuit and atmospheric conductivity

The Earth’s global atmospheric electric circuit depends on the upper and lower atmospheric boundaries formed by the ionosphere and the planetary surface. Thunderstorms and electrified rain clouds drive a DC current (∼1 kA) around the circuit, with the current carried by molecular cluster ions; lightning phenomena drive the AC global circuit. The Earth’s near-surface conductivity ranges from 10−7 S m−1 (for poorly conducting rocks) to 10−2 S m−1 (for clay or wet limestone), with a mean value of 3.2 S m−1 for the ocean. Air conductivity inside a thundercloud, and in fair weather regions, depends on location (especially geomagnetic latitude), aerosol pollution and height, and varies from ∼10−14 S m−1 just above the surface to 10−7 S m−1 in the ionosphere at ∼80 km altitude. Ionospheric conductivity is a tensor quantity due to the geomagnetic field, and is determined by parameters such as electron density and electron–neutral particle collision frequency. In the current source regions, point discharge (coronal) currents play an important role below electrified clouds; the solar wind-magnetosphere dynamo and the unipolar dynamo due to the terrestrial rotating dipole moment also apply atmospheric potential differences. Detailed measurements made near the Earth’s surface show that Ohm’s law relates the vertical electric field and current density to air conductivity. Stratospheric balloon measurements launched from Antarctica confirm that the downward current density is ∼1 pA m−2 under fair weather conditions. Fortuitously, a Solar Energetic Particle (SEP) event arrived at Earth during one such balloon flight, changing the observed atmospheric conductivity and electric fields markedly. Recent modelling considers lightning discharge effects on the ionosphere’s electric potential (∼+250 kV with respect to the Earth’s surface) and hence on the fair weather potential gradient (typically ∼130 V m−1 close to the Earth’s surface. We conclude that cloud-to-ground (CG) lightning discharges make only a small contribution to the ionospheric potential, and that sprites (namely, upward lightning above energetic thunderstorms) only affect the global circuit in a miniscule way. We also investigate the effects of mesoscale convective systems on the global circuit.

Children's sociospatial (re)production of disability within primary school playgrounds

There is a contemporary shift in the institutional context of 'disabled' children's education in the United Kingdom from segregated special to mainstream schools. This change is tied to wider deinstitutionalised or reinstitutionalised geographies of disabled people, fragile globalised educational 'inclusion' agendas, and broader concerns about social cohesiveness. Although coeducating children is expected to transform negative representations of (dis)ability in future society, there are few detailed explorations of how children's everyday sociospatial practices (re)produce or transform dominant representations of (dis)ability. With this in mind, children's contextual and shifting performances of (dis)ability in two case study school playground (recreational) spaces are explored. The findings demonstrate that children with mind-body differences are variously (dis)abled, in comparison with sociospatially shifting norms of ability, which have body, learning, and emotional-social facets. The discussion therefore places an emphasis on the need to incorporate 'intellectual' and 'emotional' differences more fully into geographical studies of disability and identity. The paper has wider resonance for transformative expectations placed on colocating children with a variety of 'axes of difference' (such as gender, 'race, ethnicity, and social class) in schools.

Comparison of methane produced by straw fed sheep in open-circuit respiration with methane predicted by fermentation characteristics measured by an in vitro gas procedure

Reducing carbon conversion of ruminally degraded feed into methane increases feed efficiency and reduces emission of this potent greenhouse gas into the environment. Accurate, yet simple, predictions of methane production of ruminants on any feeding regime are important in the nutrition of ruminants, and in modeling methane produced by them. The current work investigated feed intake, digestibility and methane production by open-circuit respiration measurements in sheep fed 15 untreated, sodium hydroxide (NaOH) treated and anhydrous ammonia (NH3) treated wheat, barley and oat straws. In vitro fermentation characteristics of straws were obtained from incubations using the Hohenheim gas production system that measured gas production, true substrate degradability, short-chain fatty acid production and efficiency of microbial production from the ratio of truly degraded substrate to gas volume. In the 15 straws, organic matter (OM) intake and in vivo OM digestibility ranged from 563 to 1201 g and from 0.464 to 0.643, respectively. Total daily methane production ranged from 13.0 to 34.4 l, whereas methane produced/kg OM matter apparently digested in vivo varied from 35.0 to 61.8 l. The OM intake was positively related to total methane production (R2 = 0.81, P<0.0001), and in vivo OM digestibility was also positively associated with methane production (R2 = 0.67, P<0.001), but negatively associated with methane production/kg digestible OM intake (R2 = 0.61, P<0.001). In the in vitro incubations of the 15 straws, the ratio of acetate to propionate ranged from 2.3 to 2.8 (P<0.05) and efficiencies of microbial production ranged from 0.21 to 0.37 (P<0.05) at half asymptotic gas production. Total daily methane production, calculated from in vitro fermentation characteristics (i.e., true degradability, SCFA ratio and efficiency of microbial production) and OM intake, compared well with methane measured in the open-circuit respiration chamber (y = 2.5 + 0.86x, R2 = 0.89, P<0.0001, Sy.x = 2.3). Methane production from forage fed ruminants can be predicted accurately by simple in vitro incubations combining true substrate degradability and gas volume measurements, if feed intake is known.

Architectural, construction and environmental matters of Bahrain's international formula 1 circuit

The Bahrain International Circuit (BIC) is considered its one of the best international racing car track in terms of technical aspects and architectural quality. Two Formula 1 races have been hosted in the Kingdom of Bahrain, in 2004 and 2005, at BIC. The BIC had recently won the award of the best international racing car circuit. This paper highlights on the elements that contributed to the success of such project starting from the architectural aspects, construction, challenges, tendering process, risk management, the workforce, speed of the construction method, and future prospects for harnessing solar and wind energy for sustainable electrification and production of water for the circuit, i.e. making BIC green and environment-friendly international circuit.

Transatlantic spaces: production, location and style in 1960s-1970s action-adventure TV series

This paper argues that transatlantic hybridity connects space, visual style and ideological point of view in British television action-adventure fiction of the 1960s–1970s. It analyses the relationship between the physical location of TV series production at Elstree Studios, UK, the representation of place in programmes, and the international trade in television fiction between the UK and USA. The TV series made at Elstree by the ITC and ABC companies and their affiliates linked Britishness with an international modernity associated with the USA, while also promoting national specificity. To do this, they drew on film production techniques that were already common for TV series production in Hollywood. The British series made at Elstree adapted versions of US industrial organization and television formats, and made programmes expected to be saleable to US networks, on the basis of British experiences in TV co-production with US companies and of the international cinema and TV market.

Realism and politics in alienated space: Trevor Griffiths's plays of the 1970s in the television studio

The television studio play is often perceived as a somewhat compromised, problematic mode in which spatial and technological constraints inhibit the signifying and aesthetic capacity of dramatic texts. Leah Panos examines the function of the studio in the 1970s television dramas of socialist playwright Trevor Griffiths, and argues that the established verbal and visual conventions of the studio play, in its confined and ‘alienated’ space, connect with and reinforce various aspects of Griffiths's particular approach and agenda. As well as suggesting ways in which the idealist, theoretical focus of the intellectual New Left is reflexively replicated within the studio, Panos explores how the ‘intimate’ visual language of the television studio allows Griffiths to create a ‘humanized’ Marxist discourse through which he examines dialectically his dramatic characters' experiences, ideas, morality, and political objectives. Leah Panos recently completed her doctoral thesis, ‘Dramatizing New Left Contradictions: Television Texts of Ken Loach, Jim Allen, and Trevor Griffiths’, at the University of Reading and is now a Postdoctoral Researcher on the AHRC funded project, ‘Spaces of Television: Production, Site and Style’, which runs from July 2010 to March 2014.

Electromagnetic atmosphere-plasma coupling: the global atmospheric electric circuit

A description is given of the global atmospheric electric circuit operating between the Earth’s surface and the ionosphere. Attention is drawn to the huge range of horizontal and vertical spatial scales, ranging from 10−9 m to 1012 m, concerned with the many important processes at work. A similarly enormous range of time scales is involved from 10−6 s to 109 s, in the physical effects and different phenomena that need to be considered. The current flowing in the global circuit is generated by disturbed weather such as thunderstorms and electrified rain/shower clouds, mostly occurring over the Earth’s land surface. The profile of electrical conductivity up through the atmosphere, determined mainly by galactic cosmic ray ionization, is a crucial parameter of the circuit. Model simulation results on the variation of the ionospheric potential, ∼250 kV positive with respect to the Earth’s potential, following lightning discharges and sprites are summarized. Experimental results comparing global circuit variations with the neutron rate recorded at Climax, Colorado, are then discussed. Within the return (load) part of the circuit in the fair weather regions remote from the generators, charge layers exist on the upper and lower edges of extensive layer clouds; new experimental evidence for these charge layers is also reviewed. Finally, some directions for future research in the subject are suggested.
