Abstract:

Audiences had the opportunity to applaud for sport films at the 2011 Sundance Film Festival in Park City, UT. Two sport-themed documentary films won audience awards. The U.S. winner, Buck, follows the life of horse trainer Buck Brannaman, and Senna, a look at the life of Formula One hero Ayrton Senna, won in the international category. Other sport films screened this year included Win Win, in which Paul Giamatti stars as a volunteer high school wrestling coach; Benevides Born, about a teen female wrestler trying win a scholarship; and two short movie entries, Bike Race, an animated film about a race and a love triangle, and Skateistan: To Live and Skate Kabul, a documentary about skaters in war-torn Afghanistan. This review provides an examination of the sport films at this year’s festival and discusses the impact that this form of sport communication has on the entertainment industry.

Abstract:

Edge race-tracking is a frequently reported issue during resin transfer molding. It is caused by highly permeable channels and areas between the preform edge and cavity, which can significantly change the preform impregnation pattern. To date, information is scarce on the effect of edge race-tracking in compression resin transfer molding (CRTM). To close this gap, laboratory equipment was developed to study the CRTM preform impregnation via flow visualization experiments. The preform was thereby encapsulated in thin thermoplastic films sealing its impregnation. Film-sealed compression resin transfer molding (FS-CRTM) experiments of preforms with a small geometrical aspect ratio showed fast filling of the injection gap and a subsequent through-thickness preform impregnation. Creating an edge race-tracking channel, an additional lateral in-plane flow from the channel towards the preform center was observed, initiating soon after the injection started and caused by the spatial connection between the injection gap and the race-tracking channel. To diminish edge race-tracking, a passive flow control strategy was implemented via a split design of the upper tool to spatially isolate the injection gap from the channel and to pre-compact the preform edge. A delayed and reduced lateral race-tracking flow was observed, showing that the passive flow control strategy increases the process robustness of FS-CRTM regarding edge race-tracking effects.

Abstract:

Using archival sources from the Clarence Brown Archive at the University of Tennessee at Knoxville, newspaper clippings from a wide range of national and regional press, and unpublished interviews, this article explores how the complexities and contradictions that are central to Clarence Brown’s film version of Intruder in the Dust (1949)—complexities that, arguably, make this film the most ambiguous of all the “race issue” films released in 1949—are mirrored in the director’s own deeply divided attitude to race and to the South. These tensions also surface in the critical reception of the film in the white press, and perhaps more tellingly, in the black press of 1949. The notion that this was a film generally acclaimed in the black press can be challenged, or at the very least nuanced, through a closer examination of newspaper archives, which, in turn, reveals some of the divisions within black intellectual circles of the late 1940s.

Abstract:

The so-called blaxploitation genre — a brand of 1970s film-making designed to engage young Black urban viewers — has become synonymous with channeling the political energy of Black Power into larger-than-life Black characters beating “the [White] Man” in real-life urban settings. In spite of their urban focus, however, blaxploitation films repeatedly referenced an idea of the South whose origins lie in antebellum abolitionist propaganda. Developed across the history of American film, this idea became entangled in the post-war era with the Civil Rights struggle by way of the “race problem film,” which identified the South as “racist country,” the privileged site of “racial” injustice as social pathology. Recently revived in the widely acclaimed works of Quentin Tarantino (Django Unchained) and Steve McQueen (12 Years a Slave), the two modes of depicting the South put forth in blaxploitation and the “race problem” film continue to hold sway to this day. Yet, while the latter remains indelibly linked, even in this revised perspective, to the abolitionist vision of emancipation as the result of a struggle between idealized, plaintive Blacks and pathological, racist Whites, blaxploitation’s troping of the South as the fulfillment of grotesque White “racial” fantasies offers a more powerful and transformative means of addressing America’s “race problem.”

Abstract:

Race in American Film is a three-volume encyclopedic treatment of race and racism in American cinema, from the early film era to modern times. The editors, Daniel Bernardi and Michael Green, address the question of “American cinema’s place in American and world culture with respect to the question of race” (xxx). For the purpose of this three-volume set, they define “race” broadly, using Omi and Winant’s definition of race as a “‘shifting yet reforming’ complex of meanings that works to shape our sense of selves and those we see as similar—thereby allowing us to see others as different.” (xxi) The concept of race, therefore, is subject to change over time and among different social groups.

Abstract:

http://dx.doi.org/10.5007/2175-8026.2016v69n2p165This article analyses John Hillcoat’s 2005 film The Proposition in relation to a spate of Australian films about violence and the (post)colonial encounter released in the early twenty-first century. Extending on Felicity Collins and Therese Davis argument that these films can be read in terms of the ways they capture or refract aspects of contemporary race relations in Australia in a post-Mabo, this article analyses how The Proposition reconstructs the trauma of the Australian frontier; how from the perspective of the twenty-first century it worries over the meaning of violence on the Australian frontier. It also explores what has become speakable (and remains unspeakable) in the public sphere about the history of the frontier encounter, especially in terms of family and race. The article argues that The Proposition and other early twenty-first century race relations films can be understood as post-reconciliation films, emerging in a period when Indigenous and non-Indigenous Australians were rethinking ideas of belonging through a prism of post-enmity and forgiveness. Drawing on the theme of violence and intimate relations in the film, this article argues that the challenges to the everyday formulation of Australian history proffered in The Proposition reveal painful and powerful differences amongst Australian citizens’ understanding of who belongs and how they came to belong to the nation. I suggest that by focusing on violence in terms of intimacy, relationships, family and kin, it is possible to see this film presented an opportunity to begin to refigure ideas of belonging.

Abstract:

This thesis draws together three strands for analysis: the social, political and historical narrative of race-relations, which has framed Måori subjectivity in the 20th and early 21st century. The themes identified are namely, the politics of representation of Måori subjectivity from extinction, to assimilation and then to biculturalism in film in eight New Zealand films: Rewi’s Last Stand (1925/40), Broken Barrier (1952), To Love a Maori (1972), Utu (1983), Ngati (1987), Mauri (1988), Once Were Warriors (1994) and Whale Rider (2002). While this claim has its roots in some of the earlier New Zealand films, the primary area of analysis will be upon the fundamental shift from 1985 onwards on the representation and interpretation of Måori subjectivity. It is argued that this fundamental shift is influenced by two significant developments in the New Zealand context: namely the Treaty of Waitangi settlement process and the State’s adoption of the socio-political ideology of biculturalism in which to theorise race-relations.

The goal of this dissertation is to examine the process of racial transformation within South Africa's documentary film industry and to assess how the nation's shifting identity is both influenced by and reflected in documentary film. Drawing examples from a diverse collection of local and international films, I have examined changes in who is making documentaries in South Africa and how, as well as the representations of race that result. In particular, I have focused on how the balance of insider vs. outsider storytelling may be shifting and to what effect. At the same time, I have qualitatively examined the representations produced by black/insider filmmakers as compared to those of white/outsider filmmakers in order to assess the impact of the filmmaker's racial status on outcomes. Finally, I have investigated ways in which the tradition of white-onblack storytelling must change in order to satisfy the political shift that has taken place in South Africa and the cultural sensitivities that have resulted.

Full text

Abstract:

Through extensive research which culminates in a choreographic component, this thesis explores the lack of diverse representation within artistic and entertainment industries in regards to race and gender. In pursuit of a concise argument, most of the focus is on race and the conditioned view of gender as binary. Looking specifically at dance and film, it considers and analyzes why this absence persists, along with ways to ensure progress. The analysis and exploration unfolds in five central chapters: Research, Conception of the Dance, One and the Same, and Try It On Make It Fit. By detailing all that goes into creating a space that consistently hinders representation of minorities, this project will provide a better understanding of how minority communities are affected as a result. With this knowledge, I hope to present solutions that are simple with an attempt to demonstrate the urgency for new methods that expand portraits of diverse and authentic representations outside of the “norm.” The significance of this project lies in the articulation of an issue that is too often ignored. Change will not happen until it becomes unacceptable for people to remain ignorant and complacent on the subject.

Abstract:

This thesis examines adaptations of William Shakespeare’s The Tragedy of Othello, the Moor of Venice (c. 1601–4) across media, comparing cinematic, televisual, musical, visual art, and online adaptations, among others, in an endeavour to determine its adaptability in various periods and cultural and societal contexts, with a focus on the issue of race. Shakespeare’s seeming endorsement of a racial stereotype has proved to be challenging in adaptations, which have not always been successful in either reproducing or interrogating the issue, despite the fact that the play has continuously been engaged with across media, periods, and cultures. Resultantly, the thesis considers the ways in which the race issues present in Othello have been exploited, adapted ‘faithfully’, ignored, and negotiated in different contexts. Sustained consideration of representations of the race issues of the play from a Western perspective has not been undertaken previously and this thesis analyses the use of Othello as a vehicle for commenting on and reflecting contemporary current events through the lenses of adaptation theory and the singular history that adaptations of Shakespeare’s work have. Initially, the thesis explores national readings of screen adaptations (from the United States, Great Britain, and outside the Anglo-American gaze), before grouping adaptations by media (such as music and online videos, as well as allusions in other media), deducing why specific adaptive trends have endured in Othellos, examining the relationship between the adaptability of the play and the media in which it is placed. A pertinent question addressed is: what is Othello’s place in adaptations of Shakespeare’s work – and how adaptable is it when both black and white performers and adapters perpetuate racial stereotypes? One conclusion drawn is that – despite its prevalence across media – Othello is inadaptable when its race issues are linked – through various methods – to the contexts in which it is placed, changing them in the process.

Abstract:

This dissertation traces the creation of identity, race, and gender ideals during a period of heightened nationalism in Mexico from 1920 through 1946. In hopes of reestablishing stability and prosperity following a decade of Revolutionary warfare, an enterprising group of mid-level bureaucrats, artists, and intellectuals devoted themselves to the creation of a unified national identity. This period of nation building coincided with a boom in visual technologies, thus popular visual culture became an important site for articulating and disseminating new nationalist ideals to the masses. Women were positioned as the ideal conduits for disseminating national identity to the masses and they increasingly bore symbols that wed Indigenous heritage with Mestizo identity in popular culture depictions. Analyzing this nation building process through the lens of beauty as it was mediated through pageants, film, photography, and other ephemera allows for insight into the construction of gendered, racialized identity ideals. While much of this visual discourse was trafficked in the realm of ideas and ephemera, it was also very much based in place. This dissertation analyzes how these projects both shaped and were influenced by efforts to modernize and preserve sites of living Aztec memory in Mexico City. Examination of this identity project in place allows for glimpses of myriad counter-narratives in which Indigenous peoples strategically engaged with and resisted imposed race and gender ideals. Finally, this dissertation considers how the Revolutionary-era conflation of race and culture laid the foundation for a contemporary multiculturalism that discursively elides the existence of widespread inequity and structural racism.

Abstract:

Using a close textual and contextual analysis, I trace themes of gender and race in the Matrix trilogy, arguing for the presence of a parallel, embedded filmic narrative, one that neatly aligns with African-American critical traditions affirming subjugated ideologies, knowledges, communities and forms. Decoding the films through the lenses of race, womanist, film studies and cultural studies theories, I explore this signified, covert storyline through phenotypes, casting choices, plot twists, and extra filmic events. In this dissertation project, I argue that their preponderance, consistency, and coherence are evidence of deliberate commentary. I further claim that that the trilogy can be reasonably understood as a historically motivated critique of Whiteness and White supremacy, offering references to American slavery and ideologies, as well as to cross-racial ideological domination and collective, coalitional and revolutionary change. Since long standing racial and gender understandings (along with their attendant domination and oppression) persist, examining popular films with transformed constructions is useful in supporting frameworks for conceptual change.

Abstract:

In a civil aero-engine transmission system a number of bearings are used for shaft location and load support. A bespoke experimental test facility in the University of Nottingham’s Gas Turbine and Transmissions Research Centre (G2TRC) was created to investigate oil shedding from a location bearing. An engine representative ball bearing was installed in the rig and under-race lubrication was supplied via under-race feed to three locations under the inner race and cage. The oil was supplied in an engine representative manner but the delivery system was modified to provide circumferentially even flow. An electromagnetic load system was designed and implemented to allow engine representative axial loads between 5 and 35 kN to be applied to the bearing. In this phase of testing the rig was operated at shaft speeds between 1,000 rpm and 7,000 rpm for a range of oil flow rates and low and high load conditions. The rig was designed with good visual access and high speed imaging was used to investigate film formation and movement on surfaces close to the bearing. This paper presents images and qualitative observations of thin film formed on the static surfaces forming the outer-periphery of the bearing compartment as well as the gap between orbiting cage and static outer race. Quantitative film thickness was obtained at two circumferential locations (90° and 270° from top dead centre) and three axial locations, through sophisticated analysis of the high speed images. The effect on film thickness of the varied parameters rotational speed, axial load and oil feed input flow rate are presented in this paper. It was observed that for all axial planes of measurement in both co-current and counter-current regions film thickness decreases with increase in shaft rotational speed. At 5,000 and 7,000 rpm film thicknesses are around 0.75 mm – 1 mm and are similar at 90° and 270°; at 3,000 rpm films tend to be somewhat thicker at around 1.5 mm – 2 mm and are thicker in the counter current region, particularly closer to the bearing. It is suggested that at higher shaft speeds interfacial shear dominates whereas at lower speed the effect of gravity in slowing the film in the counter-current region causes a measureable difference. It was further observed that increasing the input oil flow rate from 5.2 litres per minute to 7.3 litres per minute did not produce significant effect on film thickness. However, the increase of axial bearing load from 10 kN to 30 kN yielded thicker films at the location above the cage. In all cases there was waviness on the film surface at the bearing outer periphery; imaging was not sufficient to see if the film surface close to the bearing is wavy.

Abstract:

Abstract The rotor time domain orbits and the transmissibility trajectories of a rigid rotor supported on squeeze film damper (SFD) and porous squeeze film damper (PSFD) systems were investigated. Under certain system parameters, The SFD system with a centralising spring exhibits excessive nonsynchronous motions with approximate third harmonic frequencies and opposite whirling motions as well as severe transmitted forces. However, under same system parameters and with a porous permeable film outer race PSFD system could effectively attenuate the nonsynchronous motions with very small transmissibilities. The rigid rotor without a centering spring supported on SFD and PSFD systems were also investigated. The highly nonlinear film force characteristics take the major responsibility for the nonsynchronous motions of uncentralized SFD systems, and typical second and third harmonic orbits of SFD system were predicted. While under the same conditions, perfect synchronous orbits of PSFD system were resulted. PSFD through outer race permeability could provide more reasonable film force characteristics, and thus has the capability of suppressing nonsynchronous motions.

Abstract:

An efficient oil film damper known as porous squeeze film damper (PSFD) was developed for more effective and reliable vibration control of high speed rotors based on the conventional squeeze film damper (SFD). The outer race of the PSFD is made of permeable sintered porous metal materials. The permeability allows some of the oil to permeate into and seep out the porous matix, with remarkebly improvement of the squeeze film damping properties. The characteristics of PSFD oil film stiffness and damping coefficients and permeability, also, the steady state unbalance response of a simple rigid rotor and flexible Jeffcott’s rotor supported on PSFD and SFD are investigated. A typical experiment is presented. Investigations show that the nonlinear vibration characteristis of the unpressurized SFD system such as bistable jump phenomena and “lockup” at rotor pin–pin critical speeds could be avoided and virtually disappear under much greater unbalance level with properly designed PSFD system. PSFD has the potential advantages to operate effectively under relative large unbalance conditions.

Abstract:

This paper describes the use of the SHABERTH computer program supplemented with experimental temperature and skid data to quantify steady state bearing operation. Parametric studies on ball diameter and number, contact angle, curvature, grease type and preload are presented with their influence on contact stress, fatigue life, skid load, film thickness and inner and outer race temperatures. These results are compared for a steel vs. hybrid bearing set in a DB and DFSL mounting. The method presented can be applied to the design of other steel and hybrid ball thrust bearing systems.

Abstract:

This paper presents a novel approach for blade loss simulation of an aircraft gas turbine rotor mounted on rolling element bearings with squeeze film dampers. The modal truncation augmentation (MTA) method provides an efficient tool for modeling this large order system with localized nonlinearities in the ball bearings. The gas turbine engine, which is composed of the power turbine and gas generator rotors, is modeled with 38 lumped masses. A nonlinear angular contact bearing model is employed, which has ball and race degrees of freedom and uses a modified Hertzian contact force between the races and balls. This combines a dry contact force and an equivalent viscous damping force. Prediction of the maximum contact load and the corresponding stress on an elliptical contact area between the races and balls is made during the blade loss simulations. A finite-element based squeeze film damper (SFD), which determines the pressure profile of oil film and calculates damper forces for any type of whirl orbit, is developed, verified, and utilized in the simulations. The new approach is shown to provide efficient and accurate predictions of whirl amplitudes, maximum contact load and stress in the bearings, transmissibility, the maximum and minimum damper pressures and amount of unbalance force for incipient oil film cavitation.

Abstract:

Morton Effect is a known rotordynamic phenomenon associated with fluid film bearings, where viscous heating creates a uni-directional temperature rise in the bearing journal, leading to thermal growth and subsequent bow of the rotor. This results in an unbalance distribution that exacerbates the original unbalance, increasing the heating and bow, resulting in an unstable, or self-amplifying, response. Heretofore, this phenomenon has only been reported in fluid film bearings, as it is traditionally associated with the viscous heating from shearing of the oil. There is also similar behavior associated with phenomenon named the Newkirk Effect where the same mechanics of heating, thermal growth and bowing of a shaft occurs, but the source of heating is a labyrinth rub. This paper describes an incident where such a series of interactions was experienced with a rolling-element bearing (REB). Instead of being driven by viscous shearing of the oil through the minimum film clearance, the uni-directional heating of the rotor results from unbalance and the sliding or dynamic friction of the balls on the inner race or rub of a near-by seal. Rotordynamic analysis was used to derive a correlation between measured vibration levels and temperature rise resulting in predictable bowing of the shaft in a 45,000 RPM fixed speed 250 kW microturbine having an overhung rotor supported by two rolling element bearings. Vibration response was measured with proximity probes along the rotor and temperature predictions were verified against physical evidence in the bearing races. The information gained in this effort was used to establish assembly tolerance and vibration acceptance criteria for factory testing of the turbine. This behavior has internally been described as “REB Morton Effect.” The paper describes the vibration investigation; bearing evaluation; rotordynamic modeling, analysis and verification; design and assembly corrections, and subsequent testing.

Abstract:

Modern Gas turbine efficiency increase accompanied by higher turbine inlet temperature, pressure levels and rotor speeds. These demands an accurate thermal analysis of bearing compartments as large load transferred through bearings and heat load from surrounding environment. Two phase flow air &oil) is common in bearing compartments and it makes heat transfer coefficient estimation a difficult task. Bearing friction, oil churning, seals heat generations and heat input from the surroundings need to be considered accurately to predict the compartment temperatures at various operating conditions. In addition to analysis for operating conditions, bearing compartment soak back analysis is also critical for safe operation of bearings. Absence of oil flow during shutdown of the engine can cause coking of oil film due to heat soak from the hot surroundings. Accurate soak back analysis is therefore required to simulate the thermal response of the bearing compartment during shutdown. For the normal operating conditions, detailed numerical investigations are carried out to predict (i) optimal oil flow rate at a given rotor speed, (ii) maximum rotor speed allowed for the specified oil flow rate and (iii) the heat transfer rates for various air fractions of the oil & air mixture. The results are validated against available Engine data on scavenge oil and bearing race metal temperatures.
