Thermal comfort in naturally ventilated primary school classrooms

Abstract: An investigation is presented of children-s thermal sensation trends and their perception of overall comfort and tiredness in school classrooms. Findings are reported from a field survey in a naturally ventilated primary school in Southampton, UK, which included thermal comfort surveys and simultaneous measurements of indoor environmental variables. Approximately 230 pupils aged 7-11 years were surveyed from April to July 2011. During this period of the summer term, there was no heating in the school. The results are compared with findings from other studies in schools and from studies with adults in offices. The results reveal a tendency of pupils towards warm thermal sensations which paradoxically is not complemented by an equally strong preference for cooler environments. There was no difference in the thermal sensation responses in terms of gender, but boys generally preferred cooler environments at high temperatures than girls. Overall, the results indicate that children in a classroom have a different thermal perception compared with adults, suggesting that current adult-based comfort standards may not apply to school children. The study shows that adjustments may be required to current comfort criteria in order to address the thermal perception of children. More child-centred research is needed to address pupils- thermal requirements under current and future climates. © 2013 Taylor and Francis Group, LLC.

GENDER, CLASS, AND THE INTERACTION BETWEEN SOCIAL MOVEMENTS A Strike of West Berlin Day Care Workers

Abstract: From the perspective of gender theory, the intersections among gender, class, and race make it difficult, if not impossible, to assign political issues and identities to just one social movement. Instead, the negotiation of movement ownership of issues and identities occurs through interaction among social movements, including interactions that create denial and distance. This article takes the interaction of labor organizing and feminism as the lens for studying movement interaction at three levels: opportunity structure, organizing practices, and framing ideas. Using a case study of a strike of day care workers in West Berlin in the winter of 1989-90, it contrasts inclusive and exclusive forms of solidarity and their consequences for organizational practices. This particular strike received little support from either feminists or the labor movement and eventually failed, an outcome that can be seen as reflecting the weakness of structural and organizational supports for frames favoring inclusive solidarity.

Real-Time Adaptive Radiometric Compensation

Abstract: Recent radiometric compensation techniques make it possible to project images onto colored and textured surfaces. This is realized with projector-camera systems by scanning the projection surface on a per-pixel basis. Using the captured information, a compensation image is calculated that neutralizes geometric distortions and color blending caused by the underlying surface. As a result, the brightness and the contrast of the input image is reduced compared to a conventional projection onto a white canvas. If the input image is not manipulated in its intensities, the compensation image can contain values that are outside the dynamic range of the projector. These will lead to clipping errors and to visible artifacts on the surface. In this article, we present an innovative algorithm that dynamically adjusts the content of the input images before radiometric compensation is carried out. This reduces the perceived visual artifacts while simultaneously preserving a maximum of luminance and contrast. The algorithm is implemented entirely on the GPU and is the first of its kind to run in real time.
