The purpose of this thesis was to investigate the effect of exposure to multicultural and colour blind ideologies on discrimination in individual selection decisions, and diversity in team selection decisions. One hundred and fourteen participants role played a hiring manager in a large government organization, and were assigned to a multicultural, colour blind or control condition. Participants rated either an Arab Muslim or a White Canadian job applicant, and then selected a team to form a task force from a diverse pool of employees. However, the diversity ideology espoused by the organization did not have an effect on the individual or team selection decisions that participants made, or on attitudes towards diversity issues in the workplace. Possible explanations for non-significant results and implications for practice are discussed.

<p>The aim of this thesis is to develop an technical aid (software) to help people with colourblindness. Colour blind people have difficulties to differentiate between certain colours,so the implemented software will name a selected colour. The software is implementedas a Mozilla Firefox extension and also uses a XPCOM component. Furthermore canthe user select different colour databases and change the displaying properties.The aim of this thesis is to develop an technical aid (software) to help people with colourblindness.

El objetivo de esta investigación fue determinar cómo la anomalía perceptiva del color reconfigura la jerarquía visual. Por ello, la hipótesis que se planteó fue que utilizar el contraste en otros elementos gráficos, además del color, permitirá que la gráfica sea mejor percibida por personas con discromatopsia. La metodología utilizada fue, primero el cuestionario para obtener el porcentaje de medios más consumido por la muestra. Segundo, se adaptó el Checklist Sirius según los criterios que cumplían con los fundamentos de diseño de Wong. De esta forma, se recolectaron datos sobre los elementos de diseño que permiten que las personas con discromatopsia perciban con mayor efectividad el producto visual. Los resultados reflejaron que las personas con discromatopsia no presentan diferencias de percepción en cuanto al logotipo de la página web analizada y la compresibilidad de las fotografías. Sin embargo, presentan diferencias entre 16,7% y 33,3% en cuanto a la legibilidad del texto, las zonas en blanco, el uso correcto del espacio visual, los íconos, las secciones de la página, la cantidad de contenido informativo y texturas. En conclusión, se pudo confirmar que existen otros elementos visuales, además del color, que las personas con discromatopsia o tricromatopsia rojo - verde toman en cuenta para interpretar la información de la página web de El Comercio. Tanto la sobrecarga informativa y una interfaz limpia sin ruido visual, son relevantes para que la gráfica sea mejor percibida por personas con discromatopsia en comparación con personas sin anomalías perceptivas del color. / The objective of this investigation was to determine how the perceptual anomaly of color reconfigures the visual hierarchy. Therefore, the hypothesis that was raised was that using contrast in other graphic elements, in addition to color, will allow the graphic to be better perceived by people with dyschromatopsia. The methodology used was, first the questionnaire to obtain the percentage of the media most consumed by the sample. Second, the Sirius Checklist was adapted according to the criteria that met Wong’s design fundamentals. In this way, data was collected on the design elements that allow people with dyschromatopsia to perceive the visual product more effectively. The results showed that people with dyschromatopsia do not present differences in perception regarding the logo of the analysed website and the compressibility of the photographs. However, they show differences between 16,7% and 33,3% in terms of the readability of the text, the blank areas, the correct use of visual space, the icons, the sections of the page, the amount of informative content and textures. In conclusion, it was possible to confirm that there are other visual elements, in addition to color, that people with dyschromatopsia take into account to interpret the information on the website elcomerio.pe. Both, the information overload and a clean interface without visual noise are relevant elements that contribute to make the graphic better perceived by people with dyschromatopsia compared to people without perceptual color abnormalities. / Trabajo de investigación

This research is based on a case study of a former all-white Afrikaans secondary school situated in Pretoria in the Gauteng province of South Africa. The aim of this case study was to investigate and report on the complex and dynamic communicative interactions that were apparent in the events, human relationships and other elements as they unfolded and revealed themselves in desegregated classrooms in this school. I utilised an interpretive qualitative research design as my guiding methodology. This incorporated the use of semi-structured interviews, observation, video recordings, and narrative inquiry as sources of rich and layered data. My object of research was the patterns of communicative interaction that occurred between teachers and learners and between learners. My goal was to obtain a clear analytical view of the ways in which teachers and learners from diverse racial, cultural and ethnic backgrounds interacted with one another in the classroom. For this purpose I made use of multiple methods of data collection and included a variety of techniques that enabled me to triangulate the findings so as to ensure the credibility and trustworthiness of the empirical investigation. An analysis of the findings revealed that the school in which the study was conducted was beset by challenges that created communication barriers between teachers and learners and between learners and learners. Such barriers to communication became evident in the use of language, in the school’s failure to accommodate cultural differences, in the dynamics of class participation, in the use of both verbal and nonverbal forms of communication and in the prevalence of racism. However, some of the teachers and learners were conscious of these challenges and attitudes and strove to create a non-racist environment in their school that would negate the effects of the racist paradigm wherever possible. The study suggests that there is a need for the South African government to take the initiative to support all desegregated schools in various practical ways if the effects of racism are not to be passed onto the next generation of adults in our country.

The purpose of this study has been to explore which experiences of exposure transnational adoptees choses to tell about in their Instagram accounts and create an understanding for their experiences and thoughts with the help from theories and earlier research. We have by performing a netnografic study, found our empiric material from two transnational adoptees accounts on Instagram to answer our question formulations: Which experiences of exposure does transnational adoptees publish on Instagram? and: How does transnational adoptees explain the correlation between these experiences and their adoption? It appears in our empiric conclusion and in the analysis that themes of affiliation, indebtedness, racism, colour blindness and identity occur in both transnational adoptees account when it comes to exposure in relation to adoption. These experiences and thoughts are analysed with help from earlier research and theories. The theories we used are postcolonial perspective, stigma theory, intersectionality and social identity theory. In the discussion, conclusions are made about the analysis, where it among other things shows that experiences and thoughts of indebtedness appears to be a larger theme than in our selected earlier research. This phenomenon can be understood using the postcolonial theory, that gives a possible explanation about the occurrence of indebtedness. We discuss further about the relations between physical appearance, affiliation, and lack of racial reflection as how they appear to be distinctive factors for exposedness of the transnational adoptees in this study.

With increasing demand placed on online accessibility, a tool that enables developers to more easily build accessible websites for colour vision deficient (CVD) internet users becomes a crucial consideration. An extension was developed for the web browser, Google Chrome, and issues for CVD internet users were identified. The identification was based on the luminance and colour contrast between different objects next to each other on a web page, such as fonts and their background. The extension calculated how a CVD internet user would experience the colours and then checked the contrast between them. The extension's calculations and reliability was assessed through a evaluation with CVD internet users and the results suggested that it would be possible to reliably detect issues related to CVD internet users with a algorithm implemented in a Chrome extension. / Med ökande krav på tillgänglighet på internet så ökar behovet av ett verktyg som underlättar för utvecklare att bygga hemsidor för personer med defekt färgseende. Ett tilläggsprogram utvecklades för webbläsaren Google Chrome, och problem för personer med defekt färgseende identifierades. Identifikationen baserades på luminanskontrast och färgkontrast mellan olika närliggande objekt på en hemsida, så som fonter och deras bakgrund. Tilläggsprogrammet beräknade hur en person med defekt färgseende upplever färgerna på hemsidan och kontrollerar kontrasten mellan dem. Tilläggsprogrammets tillförlitlighet bedömdes med hjälp av en utvärdering genomförd med personer med defekt färgseende. Utvärderingen indikerade att det är möjligt att tillförlitligt identifiera problem relaterade till personer med defekt färgseende med hjälp av en algoritm implementerad i ett Chrome tilläggsprogram.

This study examines the everyday racism (as defined by Essed, 1991) experiences of Swedes adopted from Korea, through a narrative analysis of two autobiographical novels by adoptees, Lundberg’s Gul utanpå (2013) and Trotzig’s Blod är tjockare än vatten (1996). It also discusses the role and implications of everyday racism.The study suggests that everyday racism is a constant feature in the adoptee’s life, with much of it relating to the adoptee being racially categorised as Chinese. This paper argues that racism against adoptees is used by white Swedes to maintain boundaries of privileged white space, and stems from a fear that adoptees, Swedish in everything but skin colour, threaten to blur the boundaries of white Swedishness. The covert nature of everyday racism, combined with Sweden’s colour-blind discourse and a national myth of tolerance and anti-racism, means that such racism is often denied or goes unrecognised, and is thus legitimised.

The ability to differentiate between colours varies from individual to individual. This variation is attributed to factors such as the presence of colour blindness. Colour is used to encode information in information visualizations. An example of such an encoding is categorization using colour (e.g., green for land, blue for water).<p> As a result of the variation in colour differentiation ability among individuals, many people experience difficulties when using colour-encoded information visualizations. These difficulties result from the inability to adequately differentiate between two colours, resulting in confusion, errors, frustration, and dissatisfaction.<p> If a user-specific model of colour differentiation was available, these difficulties could be predicted and corrected. Prediction and correction of these difficulties would reduce the amount of confusion, errors, frustration, and dissatisfaction experienced by users. This thesis presents a model of colour differentiation that is tuned to the abilities of a particular user. To construct this model, a series of judgement tasks are performed by the user. The data from these judgement tasks is used to calibrate a general colour differentiation model to the user. This calibrated model is used to construct a predictor. This predictor can then be used to make predictions about the user's ability to differentiate between two colours.<p> Two participant-based studies were used to evaluate this solution. The first study evaluated the basic approach used to model colour differentiation. The second study evaluated the accuracy of the predictor by comparing its performance to the performance of human participants. It was found that the predictor was as accurate as the human participants 86.3% of the time. Using such a predictor, the colour differentiation abilities of particular users can be accurately modeled.
