Dissertations / Theses on the topic 'Color theory'

This thesis explores the potential advantages of incorporating color into musical analysis and musical concepts into art analysis. Music and the visual arts are vehicles of expression using two different perceptible waves as a medium. By comparing the physical attributes of these waves, analogous terminology between the disciplines is highlighted. Terminology parallels allow us to identify relationships between musical ideas and sonorities and color theory concepts and color harmonies. Cross-modal relationships have been explored in synesthetically inspired works in both disciplines. In Scriabin?s Prometheus, the luce presents the colors to the audience. These colors emphasize the harmonic, formal, and mystical elements of the piece. Messiaen?s Des Canyons aux etoiles features chords that were specifically included to paint the colors of the places he had visited. Sonata No. 6 by Ciurlionis is a painting that includes the three major sections of sonata form with the color changes to match. Symphony verte by Valensi includes complex structural variations and the various shading and saturations found in the timbral diversity of a symphony. Accounting for the bimodal aspects of these pieces provides us with a more concise holistic understanding of the artist?s purpose.

[ES] La visión artificial es uno de los campos en mayor crecimiento en la actualidad que, junto con otras tecnologías como la Biometría o el Big Data, se ha convertido en el foco de interés de numerosas investigaciones y es considerada como una de las tecnologías del futuro. Este amplio campo abarca diversos métodos entre los que se encuentra el procesamiento y análisis de imágenes digitales. El éxito del análisis de imágenes y otras tareas de procesamiento de alto nivel, como pueden ser el reconocimiento de patrones o la visión 3D, dependerá en gran medida de la buena calidad de las imágenes de partida. Hoy en día existen multitud de factores que dañan las imágenes dificultando la obtención de imágenes de calidad óptima, esto ha convertido el (pre-) procesamiento digital de imágenes en un paso fundamental previo a la aplicación de cualquier otra tarea de procesado. Los factores más comunes son el ruido y las malas condiciones de adquisición: los artefactos provocados por el ruido dificultan la interpretación adecuada de la imagen y la adquisición en condiciones de iluminación o exposición deficientes, como escenas dinámicas, causan pérdida de información de la imagen que puede ser clave para ciertas tareas de procesamiento. Los pasos de (pre-)procesamiento de imágenes conocidos como suavizado y realce se aplican comúnmente para solventar estos problemas: El suavizado tiene por objeto reducir el ruido mientras que el realce se centra en mejorar o recuperar la información imprecisa o dañada. Con estos métodos conseguimos reparar información de los detalles y bordes de la imagen con una nitidez insuficiente o un contenido borroso que impide el (post-)procesamiento óptimo de la imagen. Existen numerosos métodos que suavizan el ruido de una imagen, sin embargo, en muchos casos el proceso de filtrado provoca emborronamiento en los bordes y detalles de la imagen. De igual manera podemos encontrar una enorme cantidad de técnicas de realce que intentan combatir las pérdidas de información, sin embargo, estas técnicas no contemplan la existencia de ruido en la imagen que procesan: ante una imagen ruidosa, cualquier técnica de realce provocará también un aumento del ruido. Aunque la idea intuitiva para solucionar este último caso será el previo filtrado y posterior realce, este enfoque ha demostrado no ser óptimo: el filtrado podrá eliminar información que, a su vez, podría no ser recuperable en el siguiente paso de realce. En la presente tesis doctoral se propone un modelo basado en teoría de grafos para el procesamiento de imágenes en color. En este modelo, se construye un grafo para cada píxel de tal manera que sus propiedades permiten caracterizar y clasificar dicho pixel. Como veremos, el modelo propuesto es robusto y capaz de adaptarse a una gran variedad de aplicaciones. En particular, aplicamos el modelo para crear nuevas soluciones a los dos problemas fundamentales del procesamiento de imágenes: suavizado y realce. Se ha estudiado el modelo en profundidad en función del umbral, parámetro clave que asegura la correcta clasificación de los píxeles de la imagen. Además, también se han estudiado las posibles características y posibilidades del modelo que nos han permitido sacarle el máximo partido en cada una de las posibles aplicaciones. Basado en este modelo se ha diseñado un filtro adaptativo capaz de eliminar ruido gaussiano de una imagen sin difuminar los bordes ni perder información de los detalles. Además, también ha permitido desarrollar un método capaz de realzar los bordes y detalles de una imagen al mismo tiempo que se suaviza el ruido presente en la misma. Esta aplicación simultánea consigue combinar dos operaciones opuestas por definición y superar así los inconvenientes presentados por el enfoque en dos etapas.
[CAT] La visió artificial és un dels camps en major creixement en l'actualitat que, junt amb altres tecnlogies com la Biometria o el Big Data, s'ha convertit en el focus d'interés de nombroses investigacions i és considerada com una de les tecnologies del futur. Aquest ampli camp comprén diversos m`etodes entre els quals es troba el processament digital d'imatges i anàlisis d'imatges digitals. L'èxit de l'anàlisis d'imatges i altres tasques de processament d'alt nivell, com poden ser el reconeixement de patrons o la visió 3D, dependrà en gran manera de la bona qualitat de les imatges de partida. Avui dia existeixen multitud de factors que danyen les imatges dificultant l'obtenció d'imatges de qualitat òptima, açò ha convertit el (pre-) processament digital d'imatges en un pas fonamental previa la l'aplicació de qualsevol altra tasca de processament. Els factors més comuns són el soroll i les males condicions d'adquisició: els artefactes provocats pel soroll dificulten la inter- pretació adequada de la imatge i l'adquisició en condicions d'il·luminació o exposició deficients, com a escenes dinàmiques, causen pèrdua d'informació de la imatge que pot ser clau per a certes tasques de processament. Els passos de (pre-) processament d'imatges coneguts com suavitzat i realç s'apliquen comunament per a resoldre aquests problemes: El suavitzat té com a objecte reduir el soroll mentres que el real se centra a millorar o recuperar la informació imprecisa o danyada. Amb aquests mètodes aconseguim reparar informació dels detalls i bords de la imatge amb una nitidesa insuficient o un contingut borrós que impedeix el (post-)processament òptim de la imatge. Existeixen nombrosos mètodes que suavitzen el soroll d'una imatge, no obstant això, en molts casos el procés de filtrat provoca emborronamiento en els bords i detalls de la imatge. De la mateixa manera podem trobar una enorme quantitat de tècniques de realç que intenten combatre les pèrdues d'informació, no obstant això, aquestes tècniques no contemplen l'existència de soroll en la imatge que processen: davant d'una image sorollosa, qualsevol tècnica de realç provocarà també un augment del soroll. Encara que la idea intuïtiva per a solucionar aquest últim cas seria el previ filtrat i posterior realç, aquest enfocament ha demostrat no ser òptim: el filtrat podria eliminar informació que, al seu torn, podria no ser recuperable en el seguënt pas de realç. En la present Tesi doctoral es proposa un model basat en teoria de grafs per al processament d'imatges en color. En aquest model, es construïx un graf per a cada píxel de tal manera que les seues propietats permeten caracteritzar i classificar el píxel en quëstió. Com veurem, el model proposat és robust i capaç d'adaptar-se a una gran varietat d'aplicacions. En particular, apliquem el model per a crear noves solucions als dos problemes fonamentals del processament d'imatges: suavitzat i realç. S'ha estudiat el model en profunditat en funció del llindar, paràmetre clau que assegura la correcta classificació dels píxels de la imatge. A més, també s'han estudiat les possibles característiques i possibilitats del model que ens han permés traure-li el màxim partit en cadascuna de les possibles aplicacions. Basat en aquest model s'ha dissenyat un filtre adaptatiu capaç d'eliminar soroll gaussià d'una imatge sense difuminar els bords ni perdre informació dels detalls. A més, també ha permés desenvolupar un mètode capaç de realçar els bords i detalls d'una imatge al mateix temps que se suavitza el soroll present en la mateixa. Aquesta aplicació simultània aconseguix combinar dues operacions oposades per definició i superar així els inconvenients presentats per l'enfocament en dues etapes.
[EN] Computer vision is one of the fastest growing fields at present which, along with other technologies such as Biometrics or Big Data, has become the focus of interest of many research projects and it is considered one of the technologies of the future. This broad field includes a plethora of digital image processing and analysis tasks. To guarantee the success of image analysis and other high-level processing tasks as 3D imaging or pattern recognition, it is critical to improve the quality of the raw images acquired. Nowadays all images are affected by different factors that hinder the achievement of optimal image quality, making digital image processing a fundamental step prior to the application of any other practical application. The most common of these factors are noise and poor acquisition conditions: noise artefacts hamper proper image interpretation of the image; and acquisition in poor lighting or exposure conditions, such as dynamic scenes, causes loss of image information that can be key for certain processing tasks. Image (pre-) processing steps known as smoothing and sharpening are commonly applied to overcome these inconveniences: Smoothing is aimed at reducing noise and sharpening at improving or recovering imprecise or damaged information of image details and edges with insufficient sharpness or blurred content that prevents optimal image (post-)processing. There are many methods for smoothing the noise in an image, however in many cases the filtering process causes blurring at the edges and details of the image. Besides, there are also many sharpening techniques, which try to combat the loss of information due to blurring of image texture and need to contemplate the existence of noise in the image they process. When dealing with a noisy image, any sharpening technique may amplify the noise. Although the intuitive idea to solve this last case would be the previous filtering and later sharpening, this approach has proved not to be optimal: the filtering could remove information that, in turn, may not be recoverable in the later sharpening step. In the present PhD dissertation we propose a model based on graph theory for color image processing from a vector approach. In this model, a graph is built for each pixel in such a way that its features allow to characterize and classify the pixel. As we will show, the model we proposed is robust and versatile: potentially able to adapt to a variety of applications. In particular, we apply the model to create new solutions for the two fundamentals problems in image processing: smoothing and sharpening. To approach high performance image smoothing we use the proposed model to determine if a pixel belongs to a at region or not, taking into account the need to achieve a high-precision classification even in the presence of noise. Thus, we build an adaptive soft-switching filter by employing the pixel classification to combine the outputs from a filter with high smoothing capability and a softer one to smooth edge/detail regions. Further, another application of our model allows to use pixels characterization to successfully perform a simultaneous smoothing and sharpening of color images. In this way, we address one of the classical challenges within the image processing field. We compare all the image processing techniques proposed with other state-of-the-art methods to show that they are competitive both from an objective (numerical) and visual evaluation point of view.

Context Colors are an important aspect of video games, they have a key roll when designing everything from characters to world objects. Therefore designers and developers need to know what colors that are preferred over others. Objectives This paper tries to determine which color setting that is the most preferred on a game avatar. Methods To do this an experiment conducted with 15 participants. They conducted a two alternative forced choice test (2AFC) with 236 pairs of pictures. All of the 236 pairs were based on color harmonies and displayed on an avatar and a cube. The different color harmonies that were used sprung from the three primary colors of the RGB-color wheel that worked as a base in this experiment. The results that were collected went through a Chi-square test. Result Some interesting results were generated from the experiment. For instance, the most preferred color harmony for the avatar was the split complementary with the base in the primary color red. Second to that was the color harmony triad, built on the three primary colors red, green and blue. The color harmonies that had their base in the color green were with zero percent the least preferred of all harmonies. On the other hand the color harmonies that had their base in the color blue were generally the most preferred among all of the harmonies. Conclusion The main conclusion that was made and that could answer the research question was that the most preferred color harmony for the avatar was split complementary red. There were also some conclusions made that could help to create a more general preference for all kind of avatars, if this experiment would be remade on a larger scale.

A graph is (t+1)-critical if it is not t-colorable, but every proper subgraph is. In this thesis, we study the structure of critical graphs on higher surfaces. One major result in this area is Carsten Thomassen's proof that there are finitely many 6-critical graphs on a fixed surface. This proof involves a structural theorem about a precolored cycle C of length q. In general terms, he proves that a coloring, c, of C, can be extended inside the cycle, or there exists a subgraph H with at most a number of vertices exponential in q such that c can not be extended to a 5-coloring of H. In Chapter 2, we proved an alternative proof that reduces the number of vertices in H to be cubic in q. In Chapter 3, we find the nine 6-critical graphs among all graphs embeddable on the Klein bottle. In Chapter 4, we prove a result concerning critical graphs related to an analogue of Steinberg's conjecture for higher surfaces. We show that if G is a 4-critical graph embedded on surface S, with Euler genus g and has no cycles of length four through ten, then G has at most 2442g + 37 vertices.

Digital cameras use a single image sensor array with a color filter array (CFA) to measure a color image. Instead of measuring a red, green, and blue value at every pixel, these cameras have a filter built onto each pixel so that only one portion of the visible spectrum is measured. To generate a full-color image, the camera must estimate the missing two values at every pixel. This process is known as color filter array interpolation. The Bayer CFA pattern samples the green image on half of the pixels of the imaging sensor on a quincunx grid. The other half of the pixels measure the red and blue images equally on interleaved rectangular sampling grids. This thesis analyzes this problem with sampling theory. The red and blue images are sampled at half the rate of the green image and therefore have a higher probability of aliasing in the output image. This is apparent when simple interpolation algorithms like bilinear interpolation are used for CFA interpolation. Two reference algorithms, a projections onto convex sets (POCS) algorithm and an edge-directed algorithm by Adams and Hamilton (AH), are studied. Both algorithms address aliasing in the green image. Because of the high correlation among the red, green, and blue images, information from the red and blue images can be used to better interpolate the green image. The reference algorithms are studied to learn how this information is used. This leads to two new interpolation algorithms for the green image. The red and blue interpolation algorithm of AH is also studied to determine how the inter-image correlation is used when interpolating these images. This study shows that because the green image is sampled at a higher rate, it retains much of the high-frequency information in the original image. This information is used to estimate aliasing in the red and blue images. We present a general algorithm based on the AH algorithm to interpolate the red and blue images. This algorithm is able to provide results that are on average, better than both reference algorithms, POCS and AH.

Forty-two college aged participants took part in a mixed repeated measures factorial design experiment that assessed color memory as a function of condition (practice with feedback, practice without feedback and no practice), dimension (hue, saturation and lightness) and color (red, yellow, green and blue). Attention was focused on the distinction between memory color and color memory, color experience and preference, mechanisms of color perception and theories of color vision (see below). Only two significant effects were found: a significant main effect for dimension and a significant interaction between dimension and color. Pearson correlations were assessed between color memory and color experience, color preference and observer imagery. None of the correlations were significant. The results of the experiments revealed that practice does not have a significant effect on color memory and the conclusion, therefore, is that the phenomenon of color memory is not improved by practice. A tentative explanation involves the early stages of color processing which are presumed to be computational in nature and to take place independently of cognitive processes such as learning and memory, which do not take place until visual information has reached the extrastriate areas. By that time, color information has been combined with information about context, in area V4 of the human visual cortex (Zeki & Marini, 1998). Although it has been shown through this experiment that practice does not improve memory for color, the possibility remains that practice may improve memory color for specific objects - namely ecologically relevant stimuli - since memory color involves higher order processing, such as learning and memory.

Tait showed in 1878 that the Four Color Theorem is equivalent to being able to three-color the edges of any planar, three-regular, two-edge connected graph. Not surprisingly, this equivalent problem proved to be equally difficult. We consider the problem of fractional colorings, which resemble ordinary colorings but allow for some degree of cheating. Happily, it is known that every planar three-regular, two-edge connected graph is fractionally three-edge colorable. Is there an analogue to Tait’s Theorem which would allow us to derive the Fractional Four Color Theorem from this edge-coloring result?

Even before working in school as a teacher or administrator, many factors were influential in the preparation process. Given that the vast majority of teachers in the workforce come from traditional university education programs, the role that schools of education play in graduating people of color to enter the teaching force is important to examine. This qualitative case study sought to answer the following research question: What are the perceptions of educators of color with respect to their pre-service education preparation? This study falls within a broader study on the overall perceptions of educators of color with respect to the racial disproportionality and its impact on the educator pipeline and schools. Both from literature and the counter narratives of these educators of color, these topics emerged as salient: the racial diversity of universities and schools of education, the impact of barrier exams, the curriculum of schools of education, and the sense of belonging of people of color in universities and their schools of education. Semi-structured interviews with 12 educators of color in the Cityside Public Schools were examined through the lens of Critical Race Theory (CRT). Findings supported what was found in the literature regarding demographics in schools of education not favoring people of color, exams required to get into school of education being barriers, and people of color feeling disconnected from their universities in a number of ways. Further, participant interviews revealed the additional barrier posed by exams needed to gain teaching certification, the substantial value of connections at various points throughout the pre-service experience, and how important practicum and internship experiences are to aspiring educators

The purpose of this individual study was to address the gap in research and answer the following research question: How do educators of color perceive the evaluation process and its impact on their professional growth and development? It was part of a larger group case study that sought to capture the perceptions of educators of color related to racial disproportionality and its impact on the educator pipeline and schools. As educators of color work to maintain a presence within the educational system, it is essential to study how perceived biases related to race may impact the evaluation process. This single case study attempted to capture how five administrators of color and five teachers of color employed by the Cityside Public School District perceived the evaluation process used within their district. Additionally, a document review of union contracts was used to ascertain the evaluation process used by Cityside. The Critical Race Theory tenets of permanence of racism, counter storytelling and critique of liberalism provided a theoretical framework to analyze the responses given by each participant who participated in semi-structured interviews. Findings reveal that the majority of the participants do not believe the evaluation process has improved their growth and development. Other findings revealed that the racial identity and the level of cultural competency of the evaluator impacted whether or not participants believed their race was a factor in how they were evaluated

Urban Education
Ph.D.
This study examined the differences in teacher racial ideology among white teachers in urban, suburban, and rural areas. This study advances the scholarship on the ideological frames used by teachers in urban, suburban, and rural areas through an examination of the differences in teachers’ discourse and racial ideology. Using contact theory, this study employed interviews to examine teachers’ discourse related to racial inequality in education to determine whether there were similarities in teacher discourse within and across urban, suburban, and rural areas with differing racial compositions. Interviews were conducted with 42 teachers in urban, suburban, and rural school districts during the 2014-2015 school year. There were three major findings in this study. First, four original frames of color-conscious racial ideology were present in data across urban, suburban, and rural areas. Second, teachers across all areas employ the systemic responsibility frame to talk about the achievement gap, and the cultural racism frame to talk about increased violence in urban areas, revealing that teachers frame some topics similarly across areas of differing racial composition. Third, analysis of teacher racial ideologies using the eight frames of color-conscious and color-blind racial ideology reveal that teachers within Lincoln City, Gresham, and Arcadia employ specific frames within each area to talk about racial inequality in education. Further, teachers in Lincoln City and Gresham framed racial inequality in education more consistently using color-conscious frames than teachers in Arcadia, indicating that contact with outgroup members also shapes teacher racial ideology.

Quantum information technologies include secure quantum communications and ultra precise quantum sensing that are significantly more efficient than their classical counterparts. To enable such technologies, we need a scalable quantum platform in which qubits are con trollable. Color centers provide controllable optically-active spin qubits within the coherence time limit. Moreover, the nearby nuclear spins have long coherence times suitable for quantum memories. In this thesis, I present a theoretical understanding of and control protocols for various color centers. Using group theory, I explore the wave functions and laser pumping-induced dynamics of VSi color centers in silicon carbide. I also provide dynamical decoupling-based high-fidelity control of nuclear spins around the color center. I also present a control technique that combines holonomic control and dynamically corrected control to tolerate simultaneous errors from various sources. The work described here includes a theoretical understanding and control techniques of color center spin qubits and nuclear spin quantum memories, as well as a new platform-independent control formalism towards robust qubit control.

Quantum information technologies promise to offer efficient computations of certain algorithms and secure communications beyond the reach of their classical counterparts. To achieve such technologies, we must find a suitable quantum platform to manipulate the quantum information units (qubits). Color centers host spin qubits that can enable such technologies. However, it is challenging due to our incomplete understanding of their physical properties and, more importantly, the controllability and scalability of such spin qubits. In this thesis, I present a theoretical understanding of and control protocols for various color centers. By using group theory that describes the symmetry of color centers, I give a phenomenological model of spin qubit dynamics under optical control of VSi color centers in silicon carbide. I also provide an improved technique for controlling nuclear spin qubits with higher precision. Moreover, I propose a new qubit control technique that combines two methods - holonomic control and dynamical corrected control - to provide further robust qubit control in the presence of multiple noise sources. The works in this thesis provide knowledge of color center spin qubits and concrete control methods towards quantum information technologies with color center spin qubits.

The studies presented in this paper attempt to expand current knowledge about color and how it may affect human perception and behavior. Specifically, these studies focus on the color black and whether or not it has a connection with the idea of death. Examining this question through a Terror Management Theory perspective (Greenberg, Pyszczynski, & Solomon, 1986), we ran three studies. Study 1 aimed to test whether viewing black paintings increased death-thought accessibility (DTA; Greenberg, Pyszczynski, Solomon, Simon, & Breus, 1994). Study 2 tested whether participants associated the word death with the color black or other colors. Study 3 examined whether outgroup members are perceived more negatively after MS if they are wearing black rather than a neutral color. For Study 1, there was not a significant effect of color on DTA in the three conditions [F(2,81) = 1.28, p = 0.282]. However the means trended in the predicted direction. Study 2 revealed that the word death was significantly associated with black more than any other color (2 (1) = 643.63, p < .001). Study 3 is still ongoing.

Cognitive load theory explains the hardship many young learners faces when trying to learn mathematics. The human brain has a limited capacity when trying to process information. The working memory can become overloaded when trying to process too much information, and as a consequence the learner tends to give up. Designers of flight simulators describes this capacity as the pilots brainbudget. By presenting only relevant information the workload for the users can be minimized. This paper aims to study the effect of color for the purpose reducing cognitive load, by answering the following question: Can the use of color improve the learning of mathematics? An experiment was conducted in Stockholm rural area involving 147 students, aged 12-16. Four colors were carefully selected to enhance the learning material and three methods were developed for the purpose of priming colors. In order to measure the effectiveness of color-coded learning material, a digital test tool was designed.  The tool measured various variables such as time, correct answer, attempted tries etc. This allowed a comparison between color coded and grey scaled learning material.  A control group did the math test in black&white and two experimental groups did the same test with color-coded material, however one of the experimental groups was primed prior to the experiment. After the test, the participants conducted a small survey and participated in interviews discussing their perception of the color enhanced instructions. Results showed that both signaling, and priming colors have major impact on the student’s ability to solve mathematical tasks. This indicate that color can be used to facilitate the learning process of mathematics, both in regard to accuracy and reduction of time.
En utmaning för många elever är att ta del av stora mängder av information som presenteras i kurslitteratur, speciellt inom matematiken. Att lära sig komplexa matematiska formler kräver flera tunga processer från arbetsminnet som lätt blir överbelastat. Den här studien tittar på teorin om kognitiv belastning och användning av färger för att underlätta inlärandet med hjälp av signalering och priming, och ämnar att besvara frågan Kan färgkodat inlärningsmaterial förbättra inlärningen av matematik? För att göra det skapades ett digitalt verktyg för ett färgkodat matematiktest. 147 högstadieelever deltog i ett experiment där de delades in i 3 grupper. En kontrollgrupp och två experimentgrupper. Som en del av experimentet fick kontrollgruppen genomföra ett matematiktest med instruktioner i som saknade färg.  Experiment grupperna fick istället svartvitt material och experimentgrupper genomförde samma test med färgkodat material där skillnaden i resultat jämfördes. Efter testerna fick deltagarna fylla i korta enkäter, och därefter blev en del av deltagarna intervjuade i mindre grupper. Under intervjuerna fick deltagarna beskriva deras egna upplevelse kring färgkodat material. Resultatet från experimentet visade att färger hade en klart positiv inverkan på elevernas förmåga att klara uppgifter, samt påvisade kortare inlärningstid. Detta indikerar att färger kan användas för att underlätta inlärandet av matematik. Vidare kan priming leda till ännu mer effektiv inlärning. Användandet av färgkodat inlärningsmaterial uppskattades av eleverna som kände att de lärde sig bättre och behövde anstränga sig mindre.

Оформлення колірних рішень є одним з ключових аспектів у створенні дизайну мультимедіа контенту, оскільки саме завдяки ним формується безпосередня ергономічність продукту.

The creating of color solutions is one of the key aspects in the design of multimedia content, because it is thanks to them that the direct ergonomics of the product is formed. This paper examines the issues of color solutions on websites from a historical point of view, the implementation of color solutions in our time and the main aspects of color theory.

Fifty-two college-aged observers participated in an experiment assessing color memory via a PowerPoint '97 computer display program which varied one of the three dimensions of hue, saturation and lightness at a time. Consistent with previous research, errors were greater for the lightness conditions followed by saturation, and least for hue conditions Additionally, a signal detection analysis indicated that d-prime was greatest for the hue conditions, less for saturation and lowest for lightness conditions. There were also significant but unpredicted differences in response criterion which may reflect task difficulty. Scores on the Vividness of Visual Imagery Questionnaire (Marks, 1973) were, in general, not correlated with performance on these color memory tasks, inconsistent with previous research. The role of complexity of neuronal circuitry, the significance for opponent-process, trichromatic and retinex color vision theories and the relationship to Sokolov's model of color memory were discussed. Also, it was concluded that investigators of color memory using a computer display are well-advised to calibrate the monitor with a colorimeter because the internal computer units may be unreliable indexes of changes in hue, saturation and lightness.

This qualitative study focuses on looking at how GirlVentures’—a non-profit with the purpose of empowering adolescent girls to develop self confidence and leadership skills—women of color experience support within and from the organization. An analysis of the organization’s overall history, functioning, culture, and aspects of experience for participants and employees of color will be obtained from interviews, coupled with my personal experience within the organization. An analysis of strengths and areas of growth for the organization will be worked in through out the study. This study hopes to assess and contribute to a higher quality of support for women of color involved with this organization in the future.

The purpose of this study was to investigate the depiction of rainbows in the art of Frederic Church in relation to mid-nineteenth century scientific developments in order to determine Church's reliance on contemporary concerns with light and color. An examination of four Church paintings with rainbows, three oil sketches, and nearly a dozen pencil drawings shows that Church's rainbow art represents a response to mid-century cultural values connecting science and art. Changes within Church's rainbow depictions occurred as the artist explored the visual representations of light, synthesizing the scientific knowledge of light and color available to him, and reconciling that information with the requirements of art.

Les trous noirs sont produits par effondrement gravitationnel d'étoiles supermassives et contiennent en leur centre une singularité de l'espace-temps habillée d'un horizon auquel rien ne peut s'échapper. Ils se situent à la frontière théorique commune entre la Relativité Générale et la Mécanique Quantique, ce qui en fait le principal laboratoire théorique et expérimental pour tester les théories quantiques de la gravité comme la Théorie des Cordes. L'entropie d'un trou noir est énorme, de l'ordre de sa masse au carré. Comme tout objet entropique, une description microscopique en termes de dégénérescence d'états devrait exister. De plus, le trou noir s'évapore par rayonnement d'Hawking et l'information à l'intérieur semble perdue, ce qui compromet la principe d'unitarité, pierre angulaire de la Mécanique Quantique. Par conséquent, la Théorie des Cordes doit fournir les degrés de liberté nécessaires pour décrire la nature de micro-état de trous noirs, elle doit également trouver un mécanisme résolvant la singularité et le paradoxe de la perte d'information. Cette thèse porte sur la physique des trous noirs à travers le "fuzzball proposal" et le "microstate geometry program". La majeure partie de la discussion se déroulera dans la limite de basse énergie de la Théorie des Cordes, c'est-à-dire en Supergravité. Le ``proposal" stipule qu'il existe "eS" solutions non singulières sans horizon qui ressemblent à un trou noir à large distance mais qui diffèrent à proximité de l'horizon. Sur la base de cette affirmation, la solution de trou noir classique correspond à la description statistique d'un système de solutions qui ont la même géométrie que le trou noir à l'extérieur de l'horizon, mais qui se terminent par des géométries régulières, dites "fuzzy". La proposition soulève plusieurs questions : Comment la singularité est-elle résolue ? De telles géométries peuvent-elles être construites en Supergravité ? Comment l'information s'échappe-t-elle de l'ensemble des micro-états ? La thèse est décomposée en trois parties. La première partie présente les bases et donne un aperçu du "microstate geometry program". La deuxième partie regroupe cinq travaux qui se consacrent à construire de larges familles de micro-états de trous noirs supersymétriques ou non supersymétriques. La dernière partie passe en revue deux travaux. L'un d'eux étudie le processus de diffusion dans les micro-états. Cela permet d'élucider comment le principe d'unicité est restaurée et comment l'information s'échappe des micro-états. La seconde traite du rôle des micro-états dans le contexte de la correspondance AdS2/CFT1 et donne l'ébauche d'une preuve pour le "fuzzball proposal"
Black holes are produced by gravitational collapse of supermassive stars and consist of a spacetime singularity dressed by a horizon from which nothing can escape. They lie at the common theoretical border between General Relativity and Quantum Mechanics, making them the main theoretical and experimental laboratory for testing quantum theories of gravity as String theory. The entropy of a black hole is huge, of the order of its mass squared. As any entropic object, a microscopic description in terms of large degeneracy of states should exist. Moreover, black hole evaporates through thermal Hawking's radiation and the information in the interior seems lost, that compromises the unitary principle, a cornerstone of Quantum Mechanics. Therefore, String Theory must provide the degrees of freedom necessary to describe the microstate nature of black holes, it must also find a mechanism resolving the singularity and the information loss paradox. This thesis addresses black-hole physics through the lens of the fuzzball proposal and the microstate geometry program. The major part of the discussion will be conducted in the low-energy limit of String Theory, that is in Supergravity. The proposal states that there exist "eS" horizonless non-singular solutions that resemble a black hole at large distance but differ in the vicinity of the horizon. Based on this statement, the classical black-hole solution corresponds to the average description of a system of solutions which match the black-hole geometry outside the horizon but cap off as ``fuzzy" smooth geometries in the infrared. The proposal leads to several questions: How is the singularity resolved? Can "eS" such geometries be built in Supergravity? How does the information escape from the ensemble of microstates?The thesis is decomposed in three parts. The first part introduces the basic materials and gives a review of the microstate geometry program. The second part gathers five works that all consist in constructing large classes of smooth horizonless microstate geometries of supersymmetric or non-supersymmetric black holes. The last part review two works. One is investigating the scattering process in microstate geometries. This helps to elucidate how unitarity is restored and how information escapes from black-hole backgrounds. The second one addresses the role of microstate geometries in the context of the AdS2/CFT1 correspondence and gives a beginning of proof for the fuzzball proposal

Peter Paul Rubens' creative genius, as expressed with consummate mastery in his paintings, is but one of the many elements that have compounded to establish his fame. He is also renowned as a man of immense erudition. Indeed, his reputation is such that it is taken for granted that his great learning informed all aspects of his art in a fundamental way.
In accordance with this kind of thinking, current scholarship on Rubens accepts, as a matter of course, that the artist, whilst creating his painted works, followed the dictates of a colour theory, as we would know it today. In fact, on the basis of circumstantial evidence, it has been accepted that Rubens invented a colour theory that may be seen as innovative for his time.
This thesis assesses the evidence which has led researchers to formulate such a conclusion. As a consequence, it investigates the circumstances of Rubens association with Francois de Aguilon during the final stages of the latter's publication of his book on optics, the Opticorum libri sex. ... As well, the artist's correspondence with his friend, Nicolas Fabri de Peiresc, which contains allusions to an autograph manuscript purported to contain Rubens' thoughts on colour, is re-examined. Indeed, this very correspondence reveals that Rubens did not consider himself particularly knowledgeable about the theoretical aspects colour.
On the basis of a thorough review of these existing documents; an investigation into relevant biographical circumstances; and an examination of the artist's technique, it is here proposed that Rubens did not consciously apply theoretical principles to his craft, but rather, that any of the discernable elements of what is considered to be modern colour theory are in the paintings only because the demands of the painter's craft serendipitously parallel art historians' theoretical hindsight.

This qualitative case study explored how educators of color experienced recruitment and hiring practices in the Cityside Public School District (pseudonym). It was part of a larger group case study that sought to capture the perceptions of educators of color related to racial disproportionality and its impact on the educator pipeline and schools. Two research questions guided this individual study: (1) How do Cityside educators of color experience Cityside’s recruitment and/or hiring processes? (2) What practices and policies might Cityside school and district level leaders utilize to increase the number of educators of color recruited and hired? Data for this study were collected from semi-structured interviews with nine Cityside faculty of color and with six Cityside administrators (of different races), as well as from a document review. Analysis of these data through the lens of Critical Race Theory (CRT) revealed study participants’ perception that implicit racial bias had the potential to negatively impact Cityside's hiring of educators of color. Additionally, leveraging social networks as an essential recruitment strategy to increase the presence of educators of color, and the benefits of hiring committees with a racially diverse membership, emerged as key findings. Finally, this study illuminated counter narratives that powerfully captured instances of microaggressions and perceived racism experienced by Cityside educators of color. Recommendations include requiring professional development with an anti-bias focus for all hiring committee participants, increasing the utilization of social networks to enhance recruitment efforts, ensuring a racially diverse composition of hiring committees, and actively seeking the counter narratives of Cityside educators of color

Many applications lead to signals with nonnegative function values. Understanding the structure of the spaces of nonnegative signals is therefore of interest in many different areas. Hence, constructing effective representation spaces with suitable metrics and natural transformations is an important research topic. In this thesis, we present our investigations of the structure of spaces of nonnegative signals and illustrate the results with applications in the fields of multispectral color science and content-based image retrieval. The infinite-dimensional Hilbert space of nonnegative signals is conical and convex. These two properties are preserved under linear projections onto lower dimensional spaces. The conical nature of these coordinate vector spaces suggests the use of hyperbolic geometry. The special case of three-dimensional hyperbolic geometry leads to the application of the SU(1,1) or SO 2,1) groups. We introduce a new framework to investigate nonnegative signals. We use PCA-based coordinates and apply group theoretical tools to investigate sequences of signal coordinate vectors. We describe these sequences with oneparameter subgroups of SU(1,1) and show how to compute the one-parameter subgroup of SU(1,1) from a given set of nonnegative signals. In our experiments we investigate the following signal sequences: (i) blackbody radiation spectra; (ii) sequences of daylight/twilight spectra measured in Norrk¨oping, Sweden and in Granada, Spain; (iii) spectra generated by the SMARTS2 simulation program; and (iv) sequences of image histograms. The results show that important properties of these sequences can be modeled in this framework. We illustrate the usefulness with examples where we derive illumination invariants and introduce an efficient visualization implementation. Content-Based Image Retrieval (CBIR) is another topic of the thesis. In such retrieval systems, images are first characterized by descriptor vectors. Retrieval is then based on these content-based descriptors. Selection of contentbased descriptors and defining suitable metrics are the core of any CBIR system. We introduce new descriptors derived by using group theoretical tools. We exploit the symmetry structure of the space of image patches and use the group theoretical methods to derive low-level image filters in a very general framework. The derived filters are simple and can be used for multispectral images and images defined on different sampling grids. These group theoretical filters are then used to derive content-based descriptors, which will be used in a real implementation of a CBIR.

Selecting one color can be done with relative ease, but this task becomes more difficult with each subsequent color. Colormoo is an online tool aimed at solving this problem. We implement three algorithms for generating color palettes based off of a starting color. Data is collected for each palette that is generated. Our analysis reveals two of the algorithms are preferred, but under different circumstances. Furthermore, we find that users prefer palettes containing colors that are compatible, but not too similar. With refined heuristics, we believe these techniques can be extended and applied beyond the field of graphic design alone.

This study examines experiences of racial microaggressions as related to an audience through the art of Storytelling. Integrating Performance Ethnography and Critical Race Theory, it examines how storytelling may serve to illuminate the concept of racial microaggressions. After examining the current body of work on Racism, Storytelling and Microaggression, the author moves through the stories of experiences with racial microaggression from four individuals, gathered and performed as a storytelling event, before a live audience. The communicative management methods individuals use when talking about race and racial microaggressions are explored in presentation of the audience discussion which followed the performance. The author concludes storytelling has merit as a tool for the illumination of racial microaggressions, yet the potency with which racism is ingrained in the psyche of white people in U.S. indicates significant structure must be applied to public discussions of race to support the utilization of storytelling in this manner.

This project develops extant theories of political affect and relational identification and affinity formation by tracing how the visual images of an understudied archive--American superhero comic books--work to build multiple, alternative, fitful, inchoate, and sometimes radically creative spaces for visions of the political to take shape and develop over time. By analyzing and interpreting the generic superhero phenomenon of origin stories in comic books and by mapping the formal and narrative techniques used to construct origin stories, I show how received understandings of power, order, justice, violence, whiteness, masculinity, and heteronormativity often linger outside of language in an analytically untapped relational space between bodies--the space of political affect. Visual images of superheroes thus do more than take up space within political sign-systems; I argue them as material engines of affect, as engines of potential and usefully critical political identities and affinities. Superhero comic books, a cultural form often disregarded as childish or even ideologically dangerous, are thus recovered in this project as theoretically complex, offering speculative feminisms, anti-racism, and queer temporalities that link these popular objects of visual culture to ongoing traditions of utopianism and foundational revisionism within American political culture.

Original project of Skärholmen was composed of a system of public spaces, but this was `broken´  by the closure of the connection between the two squares in 1986. Street between shopping buildings became part of the shoping mall. The current situation is dominated by the activity of consumption, and Storholmsgatan is characterized by an atmosphere of anxiety and constant over-stimutation. The project aims to think through what form of ´restoration´ of this system of public spaces could take. How can we work with quite constrained, long, linear spaces as site for architecture? What is the role of rhythm in producing experience? A theme for design is to produce spacial hierarchy and make  a contemporary variation on modernism’s approach of the funcional color in design process.

As the student population in public schools throughout the United States continues to increase in ethnic diversity, the number of college students of color majoring in teacher education have remained stagnant. The local problem addressed in the study is that despite intentional recruitment efforts, college students of color are not majoring in teacher education at a university in Ohio. Bell's critical race theory was used throughout this basic qualitative study to explore what issues influence students of color to choose majors other than teacher education. Individual student interviews with 8 students of color were conducted to answer the research question regarding issues that have influenced students of color to choose majors other than teacher education at one university in Ohio. Transcripts from interview sessions were coded and analyzed to identify emerging patterns and themes. Member checks were used for accuracy in analysis, and maximum variation, with participants from 7 different majors, served to enhance credibility. At the local setting, the implications for positive social change may include bringing awareness to issues that students of color have encountered while enrolled at the study site. A broader implication for social change may be that institutions of higher education with similar demographics could benefit from the results of this study to address similar issues regarding students of color not choosing teacher education programs.

[ES] Hoy en día es posible observar una difusión global del color blanco en el panorama de la arquitectura contemporánea. Las cuestiones vinculadas al empleo de este particular color penetran con profundas raíces en los tiempos antiguos, en la cultura, en la historia. Para buscar las razones tras el uso del blanco, la presente investigación propone un punto de vista holístico, analizando el mito, la poética y la ciencia del blanco en arquitectura. Estas tres claves de lectura del fenómeno del blanco conducen a diferentes razones para explicar su empleo. Claves de lectura que se separan exclusivamente para obtener un estudio más ordenado del tema, pero que en la complejidad de la arquitectura actúan de forma inseparable. La tesis estudia y analiza el escenario de la arquitectura contemporánea a partir del color, pero teniendo conciencia que este representa solo un parámetro entre los muchos que realizan la forma y el espacio de la arquitectura. De las obras del pasado, de los tratados y de las teorías, hoy llega una narración llena de alternancias - de épocas de revival, pero también de renacimientos y vanguardias -, un verdadero mito en el que el color blanco, a pesar de todo, resiste con constancia hasta establecerse en la memoria actual. Al acercarse a la época hodierna, los contornos de ese mito se vuelven más nítidos y precisos, y las cuestiones históricas y culturales se unen con las innovadas necesidades de la práctica arquitectónica contemporánea. Varios arquitectos emplean el blanco para sus obras y para lograr determinadas y distintas ideas. Se define entonces una poética del blanco, es decir, una forma esencialmente subjetiva de pensar y construir arquitectura. Para investigar estas instancias individuales y específicas, al análisis de obras de arquitectura se une una serie de diálogos sobre el blanco que enriquecen el tema con las experiencias directas de los arquitectos. Aunque el color sea un fenómeno por su naturaleza muy subjetivo, el empleo del blanco en arquitectura es soportado por la ciencia y, en particular, por algunas ventajas físicas y químicas. La construcción del blanco es posible gracias a varias técnicas que amplían y extienden su larga tradición constructiva gracias a la innovada eficacia de métodos antiguos, pero también con nuevas tecnologías y materiales. El estudio se enfoca en particular en el análisis de la cultura arquitectónica española, portuguesa e italiana; la investigación no se limita a estos ámbitos geográficos, extendiéndose a considerar un horizonte global para la arquitectura blanca. El análisis de las obras de arquitectura blanca publicadas en revistas científicas de relevancia internacional proporciona un dato estadístico y objetivo de la condición global de la cuestión. La definición de la tendencia contemporánea al empleo del blanco, se remonta a la segunda mitad del siglo XX, cuando algunas obras acogen los valores del mito y los renuevan de una forma actual. No obstante, la difusión global del blanco en arquitectura se debe a su capacidad de representar ideales diferentes y múltiples. Se deduce, entonces, que el blanco no es el color de una homogeneización, sino que representa un factor común a muchas experiencias de la contemporaneidad.
[CA] Hui en dia és possible observar una difusió global del color blanc en el panorama de l'arquitectura contemporània. Les qüestions vinculades a l'ús d'aquest particular color, penetren amb profundes arrels en l'antiguitat, en la cultura, en la història. Per a cercar les raons de l'ús del blanc, la present investigació proposa un punt de vista holístic, analitzant el mite, la poètica i la ciència del blanc en arquitectura. Aquestes tres claus de lectura del fenòmen del blanc conduïxen a diferents raons per explicar el seu ús. Claus de lectura que se separen exclusivament per a obtindre un estudi més ordenat del tema, però que en la complexitat de l'arquitectura actuen de forma inseparable. La tesi estudia i analitza l'escenari de l'arquitectura contemporània a partir del color, però tenint consciència que aquest representa només un paràmetre entre els molts que realitzen la forma i l'espai de l'arquitectura. De les obres del passat, dels tractats i de les teories, hui arriba una narració plena d'alternances - d'èpoques de revival, però també de renaixements i avantguardes -, un vertader mite en què el color blanc, malgrat tot, resisteix amb constància fins a establir-se en la memòria actual. A l'acostar-se a l'època hodierna, els contorns d'eixe mite es tornen més nítids i precisos, i les qüestions històriques i culturals s'uneixen amb les innovades necessitats de la pràctica arquitectònica contemporània. Diversos arquitectes empren el blanc per a les seues obres i per a aconseguir determinades i distintes idees. Es defineix llavors una poètica del blanc, és a dir, una forma essencialment subjectiva de pensar i construir arquitectura. Per a investigar estes instàncies individuals i específiques, a l'anàlisi d'obres d'arquitectura s'unix una sèrie de diàlegs sobre el blanc que enriquixen el tema amb les experiències directes dels arquitectes. Encara que el color siga un fenòmen per la seua naturalesa molt subjectiu, l'ús del blanc en arquitectura és recolzat per la ciència i, en particular, per alguns avantatges físics i químics. La construcció del blanc és possible gràcies a diverses tècniques que amplien i estenen la seua llarga tradició constructiva gràcies a la innovada eficàcia de métodes antics, però també amb noves tecnologies i materials. L'estudi s'enfoca en particular en l'anàlisi de la cultura arquitectònica espanyola, portuguesa i italiana; la investigació no es limita a aquestos àmbits geogràfics, estenent-se a considerar un horitzó global per a l'arquitectura blanca. L'anàlisi de les obres d'arquitectura blanca publicades en revistes científiques de rellevància internacional proporciona una dada estadística i un objectiu de la condició global de la qüestió. La definició de la tendència contemporània a l'ús del blanc, es remunta a la Segona meitat del segle XX, quan algunes obres acullen els valors del mite i els renoven d'una forma actual. No obstant això, la difusió global del blanc en arquitectura es deu a la seua capacitat de representar ideals diferents i múltiples. Es dedueix, llavors, que el blanc no és el color d'una homogeneïtzació, sinó que representa un factor comú a moltes experiències de la contemporaneïtat.
[EN] Today it is possible to observe a global diffusion of white color in the panorama of contemporary architecture. The issues linked to the use of this particular color, penetrate with deep roots in ancient times, in culture, in history. To find the reasons for the use of white, this research proposes a holistic point of view, analyzing the myth, the poetics and the science of white in architecture. The three keys to reading the phenomenon of white lead to different reasons to explain its use. Reading keys that are separated exclusively to obtain a more orderly study of the theme, but that in the complexity of architecture act in an inseparable way. The thesis studies and analyzes the scenario of contemporary architecture starting from color, being aware that this represents only one parameter among the many that realize the shape and space of architecture. From the works of the past, from the treatises and from the theories, today arrives a narration of continuous alternations - of epochs of revival, but also of rebirths and vanguards -, a true myth in which the white color, In spite of everything, it endures with constancy until it is established in the present memory. As we approach today's times, the outlines of this myth become clearer and more precise, and historical and cultural issues are combined with the innovated needs of contemporary architectural practice. Various architects use white for their works and to materialize certain and different ideas. This defines a poetics of white, or in other words, an essentially subjective form of thinking and building architecture. To analyze these individual and specific instances, the analysis of architectural works is accompanied by a series of dialogues on white that enrich the theme with the direct experience of architects. Although color is a very subjective phenomenon by its nature, the use of white in architecture is supported by science and, in particular, by some physical and chemical advantages. The construction of white is possible thanks to various techniques that expand and extend its long construction tradition thanks to the renewed efficiency of ancient methods, but also with new technologies and materials. The study focuses in particular on the analysis of Spanish, Portuguese and Italian architectural culture, but the research is not limited to these geographical areas, extending in considering a global horizon for white architecture. The analysis of works of white architecture published in scientific journals of international importance, provides a statistical and objective data of the global condition of the issue. The definition of the contemporary tendency to use white dates back to the second half of the twentieth century, when some works embrace the values of myth and renew it in a contemporary way. Despite this, the global diffusion of white in architecture is due to its capacity to represent different and multiple ideals. It is therefore deduced that white is not the color of homogenization, but on the contrary it is a common factor in many contemporary experiences.

Vår kunskapsöversikt fokuserar på att besvara frågan: hur kan lärare arbeta med färglärai bildundervisningen, för att öka elevers kunskap om färglära? Kunskapsöversikteninnefattar också att beskriva definitionen av färglära och hur färglära är relevant ibildundervisningen. Syftet med vår kunskapsöversikt är att presentera olikaundervisningsmodeller som innefattar färglära och vidare diskutera omundervisningsmodellerna fungerar för bildundervisningen, eller inte. För att finnarelevanta undervisningsmodeller för vår frågeställning, använder vi oss avlitteraturöversikt som metod. I sökandet efter relevanta undervisningsmodeller, märktevi att det fanns en brist på forskning kring framtagna modeller för färglära ibildundervisningen. Resultatet blev därför att vi fann några undervisningsmodeller somfungerar för vår frågeställning och några fungerar till viss del. Ett parundervisningsmodeller fungerar inte alls, men dessa undervisningsmodeller visar dockpotential för ett vidare arbete i färgundervisning och är därför med i vårkunskapsöversikt.

Building on the conceptual lens of Hero and Tolbert (1999), this study examines differences between policy restrictiveness in states with high minority populations and states with low minority populations for three policies areas: felony voting policies, Unemployment Insurance (UI) and the State Children's Health Insurance Program (SCHIP). This study examines whether states with minority populations greater than the national average have public policies that are more restrictive than states with minority populations at or below their national average and the patterns that emerged. Overall, I found higher levels of restrictive policies for states with high minority populations in the instances of felony voting policies and the Unemployment Insurance program. The findings imply a need for accountability and uniformity from the state to improve the outcomes for racial and ethnic minorities.

The rapid increase in the number of non-tenure-track faculty members (Curtis, 2014), has prompted research about this group (Allison, Lynn, and Hovermann, 2014; Coalition on the Academic Workforce, 2012; Eagan and Jaeger, 2009; Umbach, 2007). There is also a large body of literature that explores the experiences of faculty members of color (Joseph and Hirshfield, 2011; Stanley, 2006a; Turner, González, and Wood, 2008). However, there is very little research about the experiences of non-tenure-track faculty members of color (NTFOCs). This study centered the experiences of NTFOCs to understand how this group experiences racism and other forms of systematic oppression in their work environments. The theoretical frameworks for this study were critical race theory (CRT) (Bell, 1980; Delgado and Stefancic, 2012; Ladson-Billings and Tate, 1995) and critical race feminism (CRF) (Wing, 1997). Critical race methodology was integrated throughout the research process (Solórzano and Yosso, 2001; Solórzano and Yosso, 2002). The sample consisted of 24 NTFOCs who worked at four-year, historically White colleges and universities. Data was collected through semi-structured interviews. Ten themes emerged that revealed the ways NTFOCs experienced racism and marginalization in their work environments: (a) not treated like a professional; (b) lack of support; (c) formal discrimination; (d) racialized evaluations; (e) racialized and gendered microaggressions; (f) feeling unsafe in the classroom; (g) unpaid labor; (h) balancing job responsibilities; (i) lack of resources; (j) different treatment than White colleagues. Four additional themes regarding the ways NTFOCs navigated these experiences with oppression and marginalization: (a) relying on systems of support; (b) negotiating speaking out against forms of oppression; (c) disclosing personal information; (d) deciding how to interact with department/program colleagues. These findings have implications for the personal well-being of NTFOCs, how they perform their job, and their ability to gain secure employment. The findings highlight the need for campus constituents to recognize the work of NTOFCs and to create better work conditions for them.
