Rebranding Diversity: Colorblind Racism Inside The U.S. Advertising Industry

Boulton, Christopher 01 September 2012 (has links)
This dissertation examines race inequality inside the United States advertising industry. Based on qualitative fieldwork conducted at three large agencies in New York City during the summer of 2010 (including ethnographic observations, affinity-based focus groups, in-depth interviews, and open-ended surveys), I argue that the industry's good faith effort to diversify through internship-based affirmative action programs is overwhelmed by the more widespread material practices of closed network hiring--a system that advantages affluent Whites through referral hires, subjective notions of "chemistry" or "fit," and outright nepotism through "must-hires." Furthermore, the discriminatory nature of White affirmative action is hidden from view, masked by ideologies of color-blind meritocracy deployed by management and interns alike. I conclude that this disconnect between practice and ideology helps normalize and reproduce historic inequalities in the workplace by rebranding diversity as an aspect of individuality rather than a social problem best addressed at the group level.

Intergroup discrimination and the need to belong

Pehi, Phillipa TePaea, n/a January 2005 (has links)
Intergroup discrimination is a pervasive fact of life and many factors are proposed to contribute or relate to its existence and expression (e.g. Staub, 2001). Though much research in social psychology has focused on the need for positive self-esteem as an underlying motive, in the past 25 years, evidence for the role of self-esteem in intergroup discrimination has at best proved contradictory (see Long & Spears, 1997; Rubin & Hewstone, 1998). More recently, other motivational constructs for human behaviour have been proposed to play a part in intergroup discrimination (e.g. Abrams & Hogg, 2001). This thesis focuses on the need to belong (or belongingness) as this has long been recognised as a basic human need (e.g. Horney, 1945) and recently, evidence has been provided to support this assumption (e.g. Baumeister & Leary, 1995). Thus the present thesis argues that as a fundamental need, the need to belong (NTB) would be expected to play a role in intergroup discrimination. In support of this assumption, results from some empirical studies are also highly suggestive of a link between intergroup discrimination and the NTB (e.g. Marques & Paez, 1994), though the current research programme is the first to explicitly examine this link. Seven experiments employing the same basic methodology were conducted to investigate the central hypothesis that engaging in intergroup discrimination decreases the NTB. Three experiments supported the hypothesis. Experiments 2 and 3 found that the NTB decreased for New Zealanders who engaged in intergroup discrimination and Experiment 7 found that members of a minimally socially important group showed a decrease in the NTB following intergroup discrimination when measured at a group level, but not at the personal level. Experiment 1 (Chapter 5) investigated the central hypothesis utilizing the minimal group paradigm (MGP). Despite participants exhibiting intergroup discrimination when given the opportunity, there was no significant change in their reported NTB. Thus the results of this experiment did not support the central hypothesis. Experiment 2 (Chapter 6) investigated whether the central hypothesis would be supported if participants were members of a realistic and meaningful social group category (i.e. New Zealanders). Results from this experiment showed that those participants who exhibited intergroup discrimination did in fact show a significant decrease in their NTB. Experiment 3 (Chapter 7) sought to replicate these results and to control for self-esteem effects utilizing New Zealand participants. Again, results supported the central hypothesis and no effect was found for either global or collective self-esteem. To test whether this result would generalize to other social categories, Experiment 4 (Chapter 8) tested whether the NTB would be decreased after women participants engaged in intergroup discrimination. Results found there was no significant difference in the NTB between women who engaged in discrimination and those who did not. Thus the central hypothesis and the results from Experiment 2 and 3 were not supported. To then investigate whether social influence accounted for the contradictory results from Experiments 1-4, Experiment 5 (Chapter 9) required women to publicly or privately state their intergroup discrimination. No significant changes were found in the NTB (from pre- to post- allocation task) for either private or public responding conditions, whether women engaged in intergroup discrimination or not. It was then assessed whether the importance to participants of the social identity in question was a factor. Experiments 6a and 6b (Chapter 10; women and men respectively) compared the NTB of participants with low identification with their social group, to high identifying participants. For both women and men, no significant changes were found in the NTB from pre- to post-allocation task for either high or low identifiers, regardless of whether they engaged in intergroup discrimination. Thus the central hypothesis was again not supported. Finally in Experiment 7, the NTB measure was re-evaluated and items were changed to be more group-oriented, compared to the original more individually-oriented items. The procedure used for Experiment 1 (i.e. MGP) was employed for Experiment 7 (Chapter 11) with participants completing both the personal and group versions of the NTB scale. The results for the modified group NTB scale showed that for participants who engaged in intergroup discrimination, group NTB decreased significantly from pre- to post- allocation task, compared with no significant change for those participants who did not engage in discrimination. No effects were found for either control or experimental participants� responses on the original NTB scale. Thus the central hypothesis and the results from Experiments 2 and 3 were supported. Furthermore, as was found for earlier experiments, there was no effect of either personal or collective self-esteem on the results for Experiments 4- 7. Taken overall, these results indicate that there may be a relationship between intergroup discrimination and the need to belong and that this may be most appropriately assessed using a group level measure of the NTB. Moreover, these results cannot be explained on the basis of self-esteem. Results from Experiments 2 and 3 may also indicate that if the social group category is meaningful enough for the individual (e.g. nationality), significant changes for the NTB at the personal level may occur. Despite the limitations of the present research, these results indicate that the investigation of the relationship between intergroup discrimination and the need to belong may further elucidate the underlying nature of prejudice. A number of possible directions for future research are discussed.

A Comparison of a Young and Older Adult Population of Computer Users' Recognition Rates of Different Tactons Using Modulation and Simple Waveforms as Stimulus Parameters.

Jimenez, Ricardo 01 January 2012 (has links)
Tactons are tactile cues, which work in conjunction with a vibrotactile device that is placed on the body, and mechanically produces sensations on the skin surface; this allows the sense of touch to be used in Human-Computer Interaction (HCI). Effective tacton parameters of stimuli have been identified for a young population. However, studies have shown that the detection of vibrations degrades as a natural part of the aging process. Furthermore, there are a variety of different vibrotactile devices, and studies have shown that vibrotactile device type can affect detection thresholds. This presents a challenge since detection thresholds and recognition rates of different tacton cues, using one device, may not correlate to those of another. There is limited research on the effectiveness of tacton parameters and detection thresholds of simple waveforms in an older population of computer users, when using the C2 Tactor from EAI systems. This work used the C2 Tactor and stimulus parameters similar to those which have been shown to be effective in a young population, and conducted a comparison study between a young population of computer users between 18 and 25 years old and an older population of computer users between 55 and 75 years old. The study compared both groups' detection thresholds of three different simple waveforms (sinusoidal, square, and sawtooth) and found a significant increase in detection threshold by the older group. In addition a comparison of both groups' recognition rates of modulated sinusoidal waveforms was conducted and it was found that the older group had a significant decrease in recognition rates of modulated sinusoidal waveforms. In addition, it was shown that increasing the amplitude significantly improved the recognition rate of the older test group. A significant amount of variance in detection threshold and tacton recognition rates was found in the older test group, particularly those over the age of 60. The results of this study clearly showed a correlation between age, detection threshold, and recognition rates of tactons. The study shows that detection threshold and recognition rate deficiencies of older adults are functions of frequency and amplitude and not waveform or device.

Gender-related experiences of female school principals : a qualitative study of four schools in Umlazi North circuit.

Makhaye, Lindiwe. January 2012 (has links)
The study sought to explore four female school principals’ management experiences and challenges that these females encounter in their management duties. It adopted a qualitative approach inquiry, and used semi-structured interviews and observations as its methods of data collection. The objective was to examine and unveil the challenges that these principals encountered when applying for promotion into school management; some gender-based dynamics related to executing their duties and responsibilities as female school managers; the management strategies that the female principals used to cope with their management responsibilities, as well as the support they required in order to enhance their effective management in the schools. The findings reveal that female principals have, indeed encountered challenges at schools owing to their gender as females. These range from the very long period of time it took for them to be promoted into management positions to the dynamics related to managing staff meetings, which included female principals being regarded as tokens by some teachers and not being taken seriously, thereby undermining the female principals’ authority as school managers. Mainly based on the societal expectations on females to perform domestic chores, female principals in these schools have to struggle with a heavy workload of their school work which runs concurrently with their familial responsibilities (domestic chores) at home. The negative attitudes of staff and the community, which cast doubt on females’ capacity to become managers, are shown to have far-reaching adverse consequences, which affect the female principals’ ability to effectively manage the schools. However, the female principals in this study innovatively employ various management strategies to mitigate the effects of these challenges on their ability to manage the schools. These include adopting collegial (and democratic) management strategies that enable them to raise above the tide, thus challenging the stereotypic conceptions that females do not have the capacity to become effective school managers. Based on the female principals’ views and experiences, the study suggested some strategies that could be employed to support and enhance female principals’ abilities for effective school management. / Thesis (M.Ed.)-University of KwaZulu-Natal, Edgewood, 2012.

Gender Issues In Islamic Schools: A Case Study Of Two Schools In The United States

Sabbah, Hilda Yacoub 21 November 2005 (has links) (PDF)
This study sought to explore and explain how boys, girls, teachers, and principals "do gender" in Islamic schools in the United States. The goal is to seek plausible explanations of how boys and girls interact formally and informally during the day, how they create differences, and how they interact with teachers and principals. This descriptive study utilized a case study design. The education of girls is very important for their individual growth and development, as well as for the welfare of both the Islamic and American societies and nations. Therefore, scholars and educators should work together to solve problems interfering with the education of girls. Research studies indicate that issues that impact girls' education include discrimination against girls in classrooms, interaction between boys and girls, effects of gender on education, and hidden curriculum. This study is very important for the Islamic communities to improve education of girls in the United States. The value of this study is to explore and explain how boys and girls "do gender" in Islamic schools in the United States and how this "doing" affects girls' academic achievement.

Educating for citizenship : transformation and activism through reflective accountability

Dow, Martha Christine 05 1900 (has links)
This study examines the connections between a commitment to educating for citizenship in the university and pedagogical strategies used to realize the goals associated with this commitment. One of the most common themes of the political philosophy and education literature regarding citizenship has to do with communicating across our differences. I used Jodi Dean's (1996) concept of reflective solidarity to explore the possibilities of this communication, particularly in the face of claims to morality. Reflective solidarity focuses on the communicative nature of solidarity by exploring contestation across our differences as we work toward understanding. I interviewed ten educators from a variety of disciplines at the University of British Columbia to explore their experiences translating this commitment to social justice into practice. My analysis of their contributions resulted in three primary categories and numerous sub-categories of data that I referred to as (a) perspective on theory (the university as a site for citizenship education, defining educating for citizenship); (b) perspective on self (curriculum as contested space, teacher's role, selfreflective practice, solidarity through difference); and (c) perspective on other (voice, silence, listening, pluralism, safety and risk, power). All of the participants discussed the dynamics of power, voice, silence, risk, pluralism and resistance that characterize their efforts to educate in a manner that promotes social justice. The pedagogical challenge of responding to heterosexism and homophobia in the classroom was specifically identified as difficult and increasingly contentious. This theme became central as I wove together the literature, the participants' contributions and my own experiences. As a response to Dean's inattention to the context of the communicative relationships at the core of reflective solidarity, I propose the idea of reflective accountability. Reflective accountability challenges critical educators to think deeply about the sometimes taken-for-granted aspects of educating for social justice. Reflective accountability necessitates a critique of open public discourse and understanding as the unassailable cornerstone of education and highlights the possibility that there may be times when certain points of view need to be more critically examined, challenged and perhaps silenced when they are grounded in oppression.

Moteru galimybes siekti karjeros svietime / Women‘s opportunities to achieve the caree in Education

Bursova, Daivina 16 August 2007 (has links)
Darbe analizuojamos moterų galimybės švietime. Empirinio tyrimo pagalba siekiama atsakyti į klausimus: ar karjeros galimybes įtakoja asmens lytis? Ar švietimas laikomas specifine sritimi, kurioje moterims sudarytos labiau (menkiau) palankios galimybės siekti karjeros? Tyrimą aktualizuoja pastaruoju metu itin opus lygių lyčių galimybių klausimas. Nors tarptautiniai ir teisės aktai deklaruoja lygias lyčių galimybes, visgi Lietuvoje išlieka lyčių atskirties problema. Nežiūrint į tai, kad moterų išsilavinimo rodikliai didesni, labai aukšto išsilavinimo moterys retai pasiekia mokslo aukštumų. Taip pat egzistuoja profesinių veiklos sričių skirstymas į tradiciškai moteriškas ir vyriškas. Tyrimo tikslas – atskleisti, kaip moterys vertina galimybes švietime, identifikuoti svarbiausias problemas. Tyrimo rezultatai parodė, kad mažiau nei pusė rezpondenčių laiko, kad moterys turi vienodas galimybes siekti karjeros visose srityse. Tai rodo gana didelius socialinės atskirties rodiklius, moterų skeptišką požiūrį į savo galimybes ar nepasitikėjimą savo jėgomis. Beveik ketvirtadalis respondenčių darbe patyrusios diskriminaciją dėl lyties. Respondenčių dauguma (60 proc.) švietimą išskiria kaip labiau ar labiausiai palankią moterų karjerai realizuoti. Beveik pusė respondenčių nurodė egzistuojant tradiciškai moteriškas ir vyriškas profesijas, prie pirmųjų dažniausiai priskiriamas švietimas, prie antrųjų - politika. Tokia padėtis neabejotinai sąlygoja būtinybę visuomenėje optimizuoti lyčių... [toliau žr. visą tekstą] / This paper is conserned with women‘s opportunities in the education. With the help of empirical research it is tried to answer the question if the sex of a person effects caree opportunities. Also, there is a question if education is more or less beneficial sphere for women to achieve caree. The problem of equal rights for both sexes is very urgent nowadays. Although international legitimate acts regulate equal rights for both sexes, it is still a problem in Lithuania. Despite the fact that education of women is better, those with the highest results do not achieve the top of caree in science. There is also a devision between male and female jobs. The aim of the research is to reveal how women evaluate their opportunities in Education ,also, to identify the most urgent problems. The results of the research show that less than half of respondents think that women have the same opportunities for caree prospects in every sphere of life. It can be proved by social separation mark, female sceptical attitude towards caree prospects and self – inconfidence. Almost ¼ of respondents experienced descrimination at work. The majority of respondents 60 per cent assume than education is more beneficial sphere for them. Half of the respondents assume that there is a devision between male and female professions. The most female sphere is education and the most male sphere is politics , according to the respondents. This situation causes necessity to optimise realisation of equal rights... [to full text]
