    Global session types prevent participants from waiting for never coming messages. Some interactions take place just for the purpose of informing receivers that some message will never arrive or the session is terminated. By decomposing a big global type into several light global types, one can avoid such kind of redundant interactions. Lightening global types gives us cleaner global types, which keep all necessary communications. This work proposes a framework which allows to easily decompose global types into light global types, preserving the interaction sequences of the original ones but for redundant interactions.Comment: In Proceedings PLACES 2014, arXiv:1406.331

    Skin Lightening Treatments: A Review on the Effect of Intravenous Glutathione in the Disease States of Women

    Get PDF
    The skin bleaching industry is a global business with a vast array of anti-melanogenic choices including glutathione. Glutathione is synthesized in vivo but has been used as a bodily supplement by medical personnel to aid in preventative medicine. Known for its antioxidant properties, glutathione has been used for its anti-melanogenic effects. Intravenous glutathione requires more investigation to determine its safety for usage. It continues to be distributed to the cosmetic industry despite antagonism from the Philippine FDA. This study will research the potential effects of intravenous glutathione on women and it will propose the biochemical mechanisms of glutathione in induced disease states in women. The aim is to educate people about safer methods for skin lightening

    A Neural Model of First-order and Second-order Motion Perception and Magnocellular Dynamics

    A neural model of motion perception simulates psychophysical data. concerning first-order and second-order motion stimuli, including the reversal of perceived motion direction with distance from the stimulus (I display), and data about directional judgments as a function of relative spatial phase or spatial and temporal frequency. Many other second-order motion percepts that have been ascribed to a second non-Fourier processing stream can also be explained in the model by interactions between ON and OFF cells within a single, neurobiologically interpreted magnocellular processing stream. Yet other percepts may be traced to interactions between form and motion processing streams, rather than to processing within multiple motion processing strea.ms. The model hereby explains why monkeys with lesions of the parvocellular layers, but not the magnocellular layers, of the lateral geniculate nucleus (LGN) are capable of detecting the correct direction of second-order motion, why most cells in area MT are sensitive to both first-order and second-order motion, and why after APB injection selectively blocks retinal ON bipolar cells, cortical cells are sensitive only to the motion of a moving bright bar's trailing edge. Magnoccllular LGN cells show relatively transient responses while parvoccllular LGN cells show relatively sustained responses. Correspondingly, the model bases its directional estimates on the outputs of model ON and OFF transient cells that are organized in opponent circuits wherein antagonistic rebounds occur in response to stimmulus offset. Center-surround interactions convert these ON and OFF outpr1ts into responses of lightening and darkening cells that are sensitive both to direct inputs and to rebound responses in their receptive field centers and surrounds. The total pattern of activity increments and decrements is used by subsequent processing stages (spatially short-range filters, competitive interactions, spatially long-range filters, and directional grouping cells) to dntermine the perceived direction of motion

    Women over 40, foreigners of color, and other missing persons in globalizing mediascapes: understanding marketing images as mirrors of intersectionality

    No full text
    Media diversity studies regularly invoke the notion of marketing images as mirrors of racism and sexism. This article develops a higher-order concept of marketing images as “mirrors of intersectionality.” Drawing on a seven-dimensional study of coverperson diversity in a globalizing mediascape, the emergent concept highlights that marketing images reflect not just racism and sexism, but all categorical forms of marginalization, including ableism, ageism, colorism, fatism, and heterosexism, as well as intersectional forms of marginalization, such as sexist ageism and racist multiculturalism. Fueled by the legacies of history, aspirational marketing logics, and an industry-wide distribution of discriminatory work, marketing images help to perpetuate multiple, cumulative, and enduring advantages for privileged groups and disadvantages for marginalized groups. In this sense, marketing images, as mirrors of intersectionality, are complicit agents in the structuration of inequitable societies

    Women’s Disempowerment and Preferences for Skin Lightening Products that Reinforce Colorism: Experimental Evidence from India

    Global racism and colorism, the preference for fairer skin even within ethnic and racial groups, leads millions of women of African, Asian, and Latin descent to use products with chemical ingredients intended to lighten skin color. Drawing from literatures on the impact of chronic and situational disempowerment on behavioral risk-taking to enhance status, we hypothesized that activating feelings of disempowerment would increase women of color’s interest in stronger and riskier products meant to lighten skin tone quickly and effectively. In two experiments (Experiment 1: N = 253 women and 264 men; Experiment 2: replication study, N = 318 women) with distinct samples of Indian participants, we found that being in a state of psychological disempowerment (vs. empowerment) increased Indian women’s preference for stronger and riskier skin lightening products but not for milder products. Indian men’s interest in both types of products was unaffected by the same psychological disempowerment prime. Based on these findings, we recommend increased consideration among teaching faculty, research scholars, and clinicians on how feeling disempowered can lead women of color to take risks to lighten their skin as well as other issues of intersectionality and with respect to colorism. We also encourage the adoption of policies aimed at empowering women of color and minimizing access to harmful skin lightening products

    The objectives of this research entitled “Commodity Fetishism in Cosmetic Advertisement in Indonesia” were to find out how the phenomena of commodity fetishism appear in cosmetic advertisement in Indonesia and how consumers’ responses toward the phenomena of commodity fetishism. The research method was qualitative-interpretative method using text-analysis. The instrument of this research was the writer herself. The data samples of this research were the cosmetic advertisements; those were facial foam and whitening/lightening cream advertisements from some common brands in Indonesia. Based on the data analysis there were some phenomena of commodity fetishism appear in cosmetics advertisement which marked by the appearance of models, male or female who had white skin, flawless, spotless and no acnes. It seemed that was the result of the usage the product. Then the phenomenon also marked by using some hyperbolic texts, for example “ganteng maksimal”, “see results in 7 days or your money back”, “tampil terbaik”, “putih cerah hingga 3 tingkat” dan “komplit cerahnya”. The results of the interview showed that the responses from the respondents dominated by the lack of consumers’ credibility towards the products compared with the appearances in the advertisements. It could be concluded that the phenomena of commodity fetishism in cosmetics advertisements had a big impacts towards the people as the consumers and the viewers

    SAT based Enforcement of Domotic Effects in Smart Environments

    The emergence of economically viable and efficient sensor technology provided impetus to the development of smart devices (or appliances). Modern smart environments are equipped with a multitude of smart devices and sensors, aimed at delivering intelligent services to the users of smart environments. The presence of these diverse smart devices has raised a major problem of managing environments. A rising solution to the problem is the modeling of user goals and intentions, and then interacting with the environments using user defined goals. `Domotic Effects' is a user goal modeling framework, which provides Ambient Intelligence (AmI) designers and integrators with an abstract layer that enables the definition of generic goals in a smart environment, in a declarative way, which can be used to design and develop intelligent applications. The high-level nature of domotic effects also allows the residents to program their personal space as they see fit: they can define different achievement criteria for a particular generic goal, e.g., by defining a combination of devices having some particular states, by using domain-specific custom operators. This paper describes an approach for the automatic enforcement of domotic effects in case of the Boolean application domain, suitable for intelligent monitoring and control in domotic environments. Effect enforcement is the ability to determine device configurations that can achieve a set of generic goals (domotic effects). The paper also presents an architecture to implement the enforcement of Boolean domotic effects, and results obtained from carried out experiments prove the feasibility of the proposed approach and highlight the responsiveness of the implemented effect enforcement architectur

    The effects of belongingness on the Simultaneous Lightness Contrast: A virtual reality study

    Simultaneous Lightness Contrast (SLC) is the phenomenon whereby a grey patch on a dark background appears lighter than an equal patch on a light background. Interestingly, the lightness difference between these patches undergoes substantial augmentation when the two backgrounds are patterned, thereby forming the articulated-SLC display. There are two main interpretations of these phenomena: The midlevel interpretation maintains that the visual system groups the luminance within a set of contiguous frameworks, whilst the high-level one claims that the visual system splits the luminance into separate overlapping layers corresponding to separate physical contributions. This research aimed to test these two interpretations by systematically manipulating the viewing distance and the horizontal distance between the backgrounds of both the articulated and plain SLC displays. An immersive 3D Virtual Reality system was employed to reproduce identical alignment and distances, as well as isolating participants from interfering luminance. Results showed that reducing the viewing distance resulted in increased contrast in both the plain- and articulated-SLC displays and that, increasing the horizontal distance between the backgrounds resulted in decreased contrast in the articulated condition but increased contrast in the plain condition. These results suggest that a comprehensive lightness theory should combine the two interpretations
