Title: AN OVERVIEW AND EXAMINATION OF THE PREVENTION AND PUNISHMENT OF WHITE COLLAR CRIMES.
Creator: Bartels, Tyler, Guldi, Melanie, University of Central Florida
Abstract / Description: White-collar crime is explained from an economist's perspective. Economic models typically begin by assuming individuals behave rationally. By extension, economic models of crime suggest that white-collar criminals may be acting more rationally than a casual observer may assume. This thesis will identify the benefits and drawbacks of different regulations and laws by exploring several case studies of white-collar events.

Title: CRITICAL WHITE FEMINISM: INTERROGATING PRIVILEGE, WHITENESS, AND ANTIRACISM IN FEMINIST THEORY.
Creator: McFadden, Caroline, Vest, Jennifer, University of Central Florida

Show moreIt is vital that feminist theory and critical white studies be combined in order to form what I call critical white feminism. Both critical white studies and feminist studies are often limited in their ability to adequately address the complex interconnectivity of racial and gender privilege and oppression. In general, feminist scholarship produced by white feminists excludes and oppresses women of color and is therefore inadequate. I refer to this problem as white feminist racism and argue that white feminists are ignorant of the ways in which whiteness and privilege facilitate problematic theorizing. Unlike white feminist theories, the emerging field of critical white studies provides a foundation for exploring whiteness in a racist society. However, critical white theories often examine racism and whiteness without attention to gender, and are therefore inadequate, as well. Consequently, another approach is necessary for the development of liberatory theories that sufficiently conceptualize social change. As a solution to the limitations of both feminist studies and critical white studies, I propose critical white feminism, which encourages white feminists to interrogate whiteness and privilege. The purpose of critical white feminism is to a) conceptualize an inclusive and transformative antiracist feminist framework and agenda, b) challenge white feminist racism and white feminist hegemony, c) encourage open and honest communication between feminists across differences, and d) facilitate feminist solidarity and mobilization.

Show moreThe majority of the preservice teacher population is young, White, and female; however, the urban school system student population continues to become increasingly diverse, including an increasing population of underserved Black students in urban schools. The racial differences between the preservice teacher population and the urban student population complicates the challenges faced in educating Black students effectively. Teachers and students often encounter misunderstandings, and thus, utilize incompatible styles of classroom management and instruction, often resulting in Black students experiencing difficulties with learning. Many of these complications derive from the profound presence of race, racial difference, and racial inequality throughout U.S. history. The purpose of this research was to explore the racial ideas, experiences, and attitudes of preservice teachers, who self-identify as White, toward future Black students at a large, southeastern, Research I university through a qualitative interview process. More specifically, this study examined preservice teachers' cultural sensitivity towards Black students. This study also observed preservice teachers' ability to discuss these issues. Using information from a 10-question qualitative interview of three (3) research participants, this thesis explored the following questions: Research question one (RQ1): How do preservice teachers define race and racism?, Research question two (RQ2): What factors contribute to preservice teachers' racial perspectives?, and Research question three (RQ3): What are preservice teachers' attitudes towards students who are racially different from themselves, specifically Black students?

Show moreABSTRACT The Civil Rights Movement of the 1960s and 1970s profoundly changed the lives of many young southern White citizens. Southern racism was a product of traditional indoctrination common in the culture of the Old South. During the generations after slavery to the Civil Rights Era, vulnerable White children were typically exposed to racist and prejudiced influences from families, fellow citizens, education, popular culture, and segregation laws established within their communities. The Civil Rights Movement brought forth elaborate legal reforms that broke segregation and enabled integration programs to take place at schools and other public institutions, which ultimately expanded many southerners' cultural awareness of different racial groups. Many accounts on the Civil Rights Movement and its relation to southern White racism are generally confined to narrow descriptions that emphasize extreme resistance measures, such as violence or civil disobedience acted out from members of the White community. Many students who do not study American history beyond the high school or college survey course levels unfortunately learn a limited history about White racism and its relation to the Civil Rights Movement. The sources commonly used in these courses include textbooks, films, and documentaries. Based in part by time and budget constraints, oral histories about White racism are often not incorporated in the classroom curricula. The available sources explain the history of White racism to a limited degree and the fact that it contributed to a mobilization effort to gain civil rights protection for racial minorities. However, they leave out other accounts about White racism relative to the history of the Civil Rights Movement. Many southern White children from this time grew up around prejudiced influences and witnessed blatant racist treatment of African Americans. During their upbringing many of these southern citizens developed solid beliefs in White supremacy and justifiable racial prejudice. Oral testimonies told by them that focus on their racism reveal social, economic, and political details which standard sources do not provide. Their stories demonstrate learned factors commonly found in racism and show how contemporary circumstances, such as living with segregation every day, can impact behaviors. Many common social factors that relate to understanding the roots of southern White racism are often not provided in sources used in most American history courses. Such works leave out a significant percentage of stories from regular White people from the South, and in particular many young individuals, who throughout the Civil Rights Era showed passive contempt, i.e., remaining silent on issues of overt discrimination and racism, toward African Americans as a result of cultural indoctrination. These White individuals' resistances and their youth illustrate a different aspect of prejudice in contrast to the traditional reports on the topic that highlight hate crimes and more stubborn forms of racism. Passivity expressed by these southern White citizens enabled them to reform their prejudices through the encouragement of the Civil Rights Movement. The impact of the era on their thinking offers an important lens that illustrates Civil Rights Movement and southern segregation history. Yet, generally, such perceptions are ignored in many historical works. This thesis attempts to bring out the social and evolutionary elements of White racism in the twentieth century South and the impact of the Civil Rights Movement on White prejudiced behaviors once traditionally found in southern culture that date back to the end of the Civil War and the birth of segregation. In reference to the use of capitalization of certain words I have placed capitals on terms that refer to periods of time such as the Civil Rights Era or events like the Civil Rights Movement. Additionally, groups of people identified with a racial group received recognition with a capital letter. Some of the sources I used from previous eras do not apply capitalization with specific color group terms such as "black" or "white," and I have left them as they are printed in their works. As I explain the evolution of racism and prejudice in the first half of the twentieth century, I also want to illustrate the evolution of racial labeling from the past three decades. For example, textbooks from the early 1990s describe African Americans and Caucasians as "black" and "white." However, texts from the twenty-first century label these groups as either "African Americans" or "White." The purpose of this is to show that many American historians and authors continue to evolve their understanding of racial identification.

Show moreThe main goal of this dissertation is to introduce and demonstrate a new method for the rapid determination of the nonlinear absorption spectra and the dispersion of the nonlinear refraction of optical materials in the visible and near IR spectral regions. However, conventional methods like, white-light continuum pump-probe and Z-scan techniques were used to measure the peak 2PA cross-sections for a number of commercially available photoinitiators. In the new method mentioned above, a high energy, broadband femtosecond white-light continuum is used to replace the single wavelength source conventionally used in a Z-scan experiment. In a Z-scan experiment, the transmittance of a focused beam through a sample is monitored as the sample travels through the focus, in the Z direction, along the focused beam. Providing the sample exhibits nonlinear absorption and/or refraction, the detector monitors a change in transmittance and/or a change in the beam divergence (if the energy is partially collected through an aperture in front of the detector). Replacing the single wavelength source with a white-light continuum allows for a much faster way of measuring nonlinear absorption/refraction spectra. This could eliminate the need for using other tunable sources (e.g. Optical Parameter Generators/Amplifiers) for nonlinear measurements. These sources made nonlinear spectroscopy using Z-scan experiments a time consuming task. This new source/method allows for rapid and simultaneous measurement of the nonlinear absorption spectrum and the dispersion of the nonlinear refraction. We have confirmed the functionality of the continuum as a source for nonlinear optical characterization of materials by using it to perform Z-scans on the well characterized semiconductors ZnSe and ZnS and on solutions of organic dyes.

Show moreThis study was conducted to explore the phenomenon of White male membership in a historically Black fraternity. The researcher utilized a qualitative research methodology to investigate the pre-collegiate experiences of White males that influenced them to seek membership in Alpha Phi Alpha Fraternity, Inc. Due to the national pool of potential participants, interviews were conducted with White male members of this fraternity using video chat software. The researcher utilized social identity theory (SIT) as the framework for this study based on the premise that in-groups might prove to be significant. Examining the participants' pre-collegiate in-groups, diversity of family and family friends, and home environment provided insight into participants' reasoning for seeking membership. Additionally, exploring the participants' pre-membership perceptions of their eventual fraternity revealed further detail as to the extent to which individuals became members of the in-group associated with that fraternity. Findings for this study were that participants' comfort levels with diverse backgrounds and individuals allowed them to feel comfortable seeking membership in a Black fraternity. It was also found that shared traits of service and the opportunity for growth were reasons why White males sought membership in a Black fraternity.

Show moreThis work establishes a solid foundation for the use of indirect band gap semiconductors for light emitting application and presents the work on development of white light emitting diodes (LEDs) in silicon carbide (SiC). Novel laser doping has been utilized to fabricate white light emitting diodes in 6H-SiC (n-type N) and 4H-SiC (p-type Al) wafers. The emission of different colors to ultimately generate white light is tailored on the basis of donor acceptor pair (DAP) recombination mechanism for luminescence. A Q-switched Nd:YAG pulse laser (1064 nm wavelength) was used to carry out the doping experiments. The p and n regions of the white SiC LED were fabricated by laser doping an n-type 6H-SiC and p-type 4H-SiC wafer substrates with respective dopants. Cr, B and Al were used as p-type dopants (acceptors) while N and Se were used as n-type dopants (donors). Deep and shallow donor and acceptor impurity level states formed by these dopants tailor the color properties for pure white light emission. The electromagnetic field of lasers and non-equilibrium doping conditions enable laser doping of SiC with increased dopant diffusivity and enhanced solid solubility. A thermal model is utilized to determine the laser doping parameters for temperature distribution at various depths of the wafer and a diffusion model is presented including the effects of Fick's diffusion, laser electromagnetic field and thermal stresses due to localized laser heating on the mass flux of dopant atoms. The dopant diffusivity is calculated as a function of temperature at different depths of the wafer based on measured dopant concentration profile. The maximum diffusivities achieved in this study are 4.6110-10 cm2/s at 2898 K and 6.9210-12 cm2/s at 3046 K for Cr in 6H-SiC and 4H-SiC respectively. Secondary ion mass spectrometric (SIMS) analysis showed the concentration profile of Cr in SiC having a penetration depth ranging from 80 nm in p-type 4H-SiC to 1.5 m in n-type 6H-SiC substrates respectively. The SIMS data revealed enhanced solid solubility (2.291019 cm-3 in 6H-SiC and 1.421919 cm-3 in 4H-SiC) beyond the equilibrium limit (31017 cm-3 in 6H-SiC above 2500 C) for Cr in SiC. It also revealed similar effects for Al and N. The roughness, surface chemistry and crystalline integrity of the doped sample were examined by optical interferometer, energy dispersive X-ray spectrometry (EDS) and transmission electron microscopy (TEM) respectively. Inspite of the larger atomic size of Cr compared to Si and C, the non-equilibrium conditions during laser doping allow effective incorporation of dopant atoms into the SiC lattice without causing any damage to the surface or crystal lattice. Deep Level Transient Spectroscopy (DLTS) confirmed the deep level acceptor state of Cr with activation energies of Ev+0.80 eV in 4H-SiC and Ev+0.45 eV in 6H-SiC. The Hall Effect measurements showed the hole concentration to be 1.981019 cm-3 which is almost twice the average Cr concentration (11019 cm-3) obtained from the SIMS data. These data confirmed that almost all of the Cr atoms were completely activated to the double acceptor state by the laser doping process without requiring any subsequent annealing step. Electroluminescence studies showed blue (460-498 nm), blue-green (500-520 nm) green (521-575 nm), and orange (650-690 nm) wavelengths due to radiative recombination transitions between donor-acceptors pairs of N-Al, N-B, N-Cr and Cr-Al respectively, while a prominent violet (408 nm) wavelength was observed due to transitions from the nitrogen level to the valence band level. The red (698-738 nm) luminescence was mainly due to metastable mid-bandgap states, however under high injection current it was due to the quantum mechanical phenomenon pertaining to band broadening and overlapping. This RGB combination produced a broadband white light spectrum extending from 380 to 900 nm. The color space tri-stimulus values for 4H-SiC doped with Cr and N were X = 0.3322, Y = 0.3320 and Z = 0.3358 as per 1931 CIE (International Commission on Illumination) corresponding to a color rendering index of 96.56 and the color temperature of 5510 K. And for 6H-SiC n-type doped with Cr and Al, the color space tri-stimulus values are X = 0.3322, Y = 0.3320 and Z = 0.3358. The CCT was 5338 K, which is very close to the incandescent lamp (or black body) and lies between bright midday sun (5200 K) and average daylight (5500 K) while CRI was 98.32. Similar white LED's were also fabricated using Cr, Al, Se as one set of dopants and B, Al, N as another.

Show moreThis study examined how racism and racial tensions potentially threatened the face needs of Black and White interracial couples. Specifically, this study investigated the benefit of family approval of one's interracial relationship. Couples use of corrective face work in response to prejudice was also examined. This research used a qualitative, interpretive method to gather and analyze data from 14 personal interviews. The interview schedule enabled interviewees to use storytelling to share their experience of being in a Black and White interracial relationship. Interviewees were asked questions surrounding their experience as the partner in an interracial relationship. Couples shared how they told their family that their romantic partner was a different race and shared how they encountered prejudice when they are out in public. Further, they spoke about how people stare at them and make comments about their interracial relationship. The data underwent a thematic analysis (Owen, 1984) where I reviewed the data and searched for themes that were recurrent and repeated by interviewees. There were several themes that emerged. First, the very presence of racial tensions and racism affects interracial couples. Second, family support seemed to mitigate threats to couples' positive and negative faces and enabled couples to engage in open and honest dialogue with their family and their significant other. Finally, even couples with family support, engaged in corrective face work to respond to the face threats posed by racism and racial tensions.

Show moreThis study demonstrates that both government officials' and the settlers' perceptions of the Seminoles and Black Seminoles in Florida were highly influenced by their paternalistic and Jeffersonian world views. These perceptions also informed their policies concerning the Seminoles and Black Seminoles. The study is separated into three sections. The first chapter covers the years of 1820-1823. This section argues that until 1823, most settlers and government officials viewed the Seminoles as noble savages that were dependent on the U.S. Furthermore, most of these individuals saw the Black Seminoles as being secure among the Seminole Indians and as no threat to white authority. The second chapter covers the years of 1823-1828 and demonstrates that during this time most settlers began to view Seminoles outside of the reservation as threats to the frontier in Florida. This reflected the Jeffersonian world view of the settlers. Government officials, on the contrary, continued to believe that the Seminole Indians were noble savages that were no threat to the frontier because of their paternal world view. Both groups by 1828 wanted the Seminoles and Black Seminoles separated. The final chapter covers the years of 1829-1836. It argues that by 1835 both settlers and government officials believed that the Seminoles and Black Seminoles were clear threats to the frontier because of the fear of a slave revolt and the beginning of Seminole resistance to removal. Most of the shifts in the perception of the Seminoles and Black Seminoles by government officials and the settlers were the result of their white gender and racial world views that then in turn affected their policies towards the Seminoles and Black Seminoles.

It analyzes the ways in which these men and women confronted the differences they encountered in Florida's southern society as compared to their experiences living in a northern society. School catalogs, school reports, letters, and newspapers highlight the ways in which these northerners explained the culture and behaviors of southern freedmen and poor whites in Jacksonville, Gainesville, and Monticello. This study examines how these particular northern men and women present in Florida during Reconstruction applied elements of "the North" to their interactions with the freedmen and poor whites. Ultimately, it sheds light on northern Methodist middle class values in southern society.

Therefore, this study explored the lived experiences of high-achieving Black female students, focusing particularly on the experiences which contribute to their success at a PWI. The qualitative phenomenological research design was used to highlight emergent themes revealed during the study. Eight purposely selected students participated in one-on-one semi structured interviews and a Sister Circle group process.The participants' stories were highlighted both independently and collectively, reflecting a wide range of sentiments. During the data analysis process, there were six themes that emerged from the data which highlighted the experiences which contributed to the students' success at a PWI. Those themes included: 1) Support, 2) Processing Situations, 3) Defining Success, 4) Involvement, 5) Motivation, and 6) Background. The emergent themes provided strategies and recommendations for Black female students, higher education practitioners, and institutions. These recommendations included areas regarding programming, retention and recruitment strategies, resource creation, and relationship building. Additionally, implications were made for future research initiatives. The data, coupled with the researcher's reflections served as the basis for the implications and recommendations for this study.

The ability to generate a high-quality, high-spectral-irradiance source of radiation confined in a single beam that spans the visible and near-infrared spectral regimes has great utility for nonlinear measurement methods such as the Z-scan technique. Using a broadband WLC instead of conventional tunable sources of radiation such as optical parametric generators/amplifiers has been shown to increase the efficiency of such measurements by nearly an order of magnitude. Although WLC generation has many complex processes involved, and complete models of the process involve highly complex numerical modeling, simple models can still guide us in the optimization of systems for WLC generation. In this dissertation the effects of two key mechanisms behind WLC generation in gaseous media are explored: self-phase modulation (SPM) and ionization leading to plasma production. The effects of SPM are largely dependent upon the third-order nonlinear refractive index, n2, of the gaseous medium whereas the effects of plasma production are dependent upon many parameters including the initial number density, ionization potential/energy, and the rate of ionization production. It is found that in order to generate a stable WLC suitable for nonlinear spectroscopy, the phase contributions from SPM and plasma production should be nearly equal. This guided our experiments in inert gases using mJ level, 150 fs-FWHM (full-width at half-maximum) pulses at 780 nm as well as 40 fs-FWHM pulses primarily at 1800 nm to create a stable, high-spectral-irradiance WLC. The generated WLC is shown to have sufficient spectral energy and spatial quality suitable for nonlinear spectroscopic measurements. In addition to extending the WLC bandwidth by using a long wavelength (1800 nm) pump source, it is found that by using a secondary weak seed pulse with a peak irradiance three orders of magnitude less than the main pulse, the spectral energy density is enhanced by more than a factor of 3 in Krypton gas for a WLC spectrum that spans over 2 octaves. Numerical simulations are presented which qualitatively describe the experimental results. The spectral enhancement of the WLC by seeding is also demonstrated for other inert gases and condensed media. Other efforts described in this dissertation include the development of the Dual-Arm Z-scan technique and its extension to measuring thin film nonlinearities in the presence of large substrate signals as well as predicting the n2 spectra of organic molecules (where we can approximate their behavior as if they were centrosymmetric) from knowledge of the one-photon and two-photon absorption spectra using a simplified sum-over-states quantum perturbative model by utilizing a quasi 3-level and quasi 4-level system.

Show moreWastewater from the textile industry is difficult to treat effectively due to the prevalent use and wide variety of synthetic dyes that are resistant to conventional treatment methods. White-rot fungi, such as Trametes versicolor, have been found to be effective in decolorizing many of these synthetic dyes and current research is focusing on their application to wastewater treatment. Although numerous studies have been conducted on the ability of both living and nonliving Trametes versicolor to separately decolorize textile dyes, no studies were found to have investigated the use of a mixture of live and dead fungus for decolorization. This study explored potential interactions between live and dead, autoclaved Trametes versicolor biomass in a mixed system by utilizing a series of batch tests with two structurally different synthetic textile dyes. Samples were analyzed by spectrophotometer and compared with controls to determine the effect of any interactions on decolorization. The results of this study indicate that an interaction between living and nonliving biomass occurred that affected the specific dye removal for both Reactive Blue 19, an anthraquinone textile dye, and Reactive Orange 16, an azo textile dye. This interaction was seen to improve the specific dye removal during the first 10-46 hours of experimentation but then diminish the specific dye removal after this period. This effect could be due to hydrophobins, which are surface-active proteins excreted by live fungi that may alter hydrophobicity. Additionally, the presence of adsorptive dead biomass could affect dye contact with degrading enzymes released from the live fungus. By expanding current knowledge of the interactions that take place in a fungal bioreactor and their effect on textile dye decolorization, this research aims to inspire more effective and less costly bioreactor designs for the treatment of textile wastewater.

Show moreThe deficit narrative about marginalized students of color attributes their failure in school to some nature of innate cognitive deficiency, cultural, social, and familial dysfunctions among other schools of thoughts. The purpose of this grounded theory study is to provide a rich description about this phenomenon and to propose theoretical pedagogical adjustments in the classroom as it relates to educating students of color. The study applies Charmaz (2014) Constructivist approach to grounded theory methods to examine the following research questions: (RQ1) How do teachers' narratives about students of color depict their teaching experiences and (RQ2) How do teachers' narratives about students of color inform students learning? Two overarching themes emerged in this study: practicing color blindness impacts cultural responsiveness while perpetuate deficit thinking, and understanding cultural background stimulates sensitivity when designing curriculum for students of color. The findings of this research demonstrate teachers' deficit thinking depicts their pedagogical practices and informs students learning. The research has both practical and theoretical implications for dispelling the deficit thinking regarding students of color.

Show moreThe purpose of this review of literature is to explore the effects of interventional and environmental auditory stimuli on the adult critical care population. Current research has yet to compare and contrast the effectiveness of various interventional auditory stimuli on stress relief, an oversight this thesis aims to remedy. Modern day critical care settings demand the identification of the most therapeutic interventional auditory stimulus and the most stress-inducing environmental stimuli, so that interventions can be made to optimize patient stress levels and improve outcomes. Suggestions will be made on how to simultaneously reduce harmful or stress inducing auditory stimuli in the critical care setting and implement the optimal stress-relieving interventional auditory stimuli.

Show moreThe 1920s represented a time of tension in America. Throughout the decade, marginalized groups created competing versions of a proper citizen. African-Americans sought to be included in the national fabric. Racism encouraged solidarity, but black Americans did not agree upon one method for coping with, and hopefully ending, antiblack racism. White women enjoyed new privileges and took on more roles in the public sphere. Reactionary groups like the Ku Klux Klan found these new voices unsettling and worrisome and celebrated a white, native-born, Protestant and male vision of the American citizen. Simultaneously, technological innovations allowed for advertising to flourish and spread homogenizing information regarding race, gender, values and consumption across the nation. These advertisements selectively represented these changes by channeling them into pre-existing prescriptive ideology. Mainstream ads, which were created by whites for white audiences, reinforced traditional ideas regarding black men and women and white women's roles. Even if white women were featured using technology or wearing cosmetics, they were still featured in prescribed roles as housekeepers, wives and mothers who deferred to and relied on their husbands. Black women were featured in secondary roles, as servants or mammies, if at all. Concurrently, the black press created its own representations of women. Although these representations were complex and sometimes contradictory and had to reach multiple audiences, black-created ads featured women in a variety of roles, such as entertainers, mothers and business women, but never as mammies. Then, in a decade of increased tensions, white-created ads relied on traditional portrayals of women and African-Americans while black-designed ads offered more positive, although complicated, visions of womanhood.

Show moreMy objective with this thesis is to understand how racist stereotypes and myths compounded the sale of fair-skinned black women during and after the slave trade in New Orleans, Louisiana. This commodification of black women's bodies continued well into the twentieth century, notably in New Orleans' vice district of Storyville. Called "quadroons" (a person with 1/4 African ancestry) and "octoroons" (1/8 African ancestry), these women were known for their "sexual prowess" and drew in a large number of patrons. The existence of "white passing" black women complicated ideas about race and racial purity in the South. Race as a myth and social construct, or as Evelyn Brooks Higginbotham explains in her essay, African-American Women's History and the Metalanguage of Race, a "metalanguage" exposes race not as a genetic fact, but rather a physical appearance through which power relations and status were to be conferred. My methodology uses race and gender theory to analyze primary and secondary sources to understand and contextualize how population demographics, myths, and liberal 18th century colonial laws contributed to the sale of black women's bodies. The works of Emily Clark, Walter Johnson, Gwendolyn Midlo Hall and other historians who utilize Atlantic history have been paramount in my research. Emily Clark has transformed the "white-black" women from a tragic, sexualized trope into a fully actualized human being, while Hall has tackled the racist underpinnings inherent in the neglect of black women's history. The writings of bell hooks, particularly her essay Eating the Other, establishes the modern day commodification of black women vis-a-vis their representation in media, as well as through the fetishism of their bodies by a white patriarchal system. During slavery plantation owners could do virtually anything they wanted with their property, including engaging in sexual intercourse. By depicting black women as hypersexual jezebels, they could justify their rape, while establishing their dominance and place in the white male hegemony of that time period. For the right price a white male of a lesser class could achieve the same thing at a brothel down in Storyville at the turn of the twentieth century, for as Emily Clark argues in her book, The Strange History of the American Quadroon, these brothels were a great equalizer, allowing all white men to experience "sexual mastery enjoyed only by elite planters before the Civil War." By democratizing white supremacy, the quadroon and others like her forged solidarity that bridge across all classes, while upholding whiteness and oppressing people of color at the same time.
