Characterizing Gender and Race in the 2000 Summer Olympics: NBC's Coverage of Maurice Greene,MichaelJohnson, Marion Jones, and Cathy Freeman

Media representations of African Americans and indigenous peoples tend to follow stereotypical notions of both gender and race. Because African Americans and indigenous peoples are gendered and racialized simultaneously by media forces, this study examines how the television network, NBC, managed portrayals of three (3) celebrated Africna American athletes and one (1) Aboriginal athlete in Sydney's 2000 Olympic Games. Specifically, the study investigates media descriptions of Maurice Greene, Michael Johnson, Marion Jones, and Cathy Freeman. Findings reveal that media presentations of African Americans men attempt to moderate threatening imagery out of sport while also promoting nationalism, and (for Greene) amplifying threatening imagery in sport. Both African American and Aboriginal Women are feminized, and political activism carried out by Aboriginal athletes is heavily mitigated by liberal pursuits of multiculturalism, as well as feminized commentary

Intersections of Culture, Migration and Intimate Partner Violence as Told by Migrant Youth

Like many other western nations, New Zealand has experienced significant migration since the mid-1980s. According to the most recent census, roughly one out of every four persons living in New Zealand is foreign born. The significant number of migrants to New Zealand of Asian and Middle Eastern ancestries has led to the development of rich and diverse ethnic enclaves. However, young people from these communities experience significant pressures to assimilate into western culture, which sometimes clash with parental desires to perpetuate cultural traditions. Drawing on 10 small group interviews conducted with 11 adolescent and 16 young adult female interviewees of Asian and Middle Eastern backgrounds in Auckland, New Zealand, this study examines how participants traverse culturally prescribed gender roles as they relate to intimate partner violence (IPV). Emergent themes from the study address participants' conceptualization of IPV, processes of learning IPV, and pressures to follow rigid gender-roles tied to IPV that are culturally embedded. The article closes with discussion on interpretation of research findings without perpetuating an Orientalist framework

Colonial Privileges in a Settler Society: Disparities of Cultural Capital in a University Setting

Drawing on forty one-on-one interviews with third year students from The University of Auckland, this study contrasts the experiences of students from working- and upper-class backgrounds. In particular, the study demonstrates how working-class students, most of whom come from Indigenous Māori and Pacific ethnic backgrounds, are forced to navigate obstacles infused with interpersonal and institutional racism. These students also report a stigmatising awareness of their lack of privilege and sense of obligation to give back to their ethnic communities. In contrast students from upper-class backgrounds, though hard-working, discuss a litany of opportunities extending their academic and occupational privilege. These capital-building opportunities are tightly connected to consistent family support in the form of gifted money, flexible work options, and networks that enhance professional experience. Working with kaupapa Māori and Bourdeausian conceptual frameworks, the study highlights privileged students’ ability to access and extend their objectified cultural capital, as less economically privileged students work their way through colonial blockades and classed pitfalls. Given the clear disparities expressed by study participants, the research suggests universities radically reframe how resources are allocated to students from diverse backgrounds

Risk and Protective Factors of Micronesian Youth in Hawai\u27i: An Exploratory Study

This exploratory, qualitative study examined the risk and protective factors of Micronesian middle and high school students in Hawai\u27i. Forty one Micronesian youth participated in 9 focus groups that explored their experiences within their schools, families, and communities. The findings describe youths\u27 experiences of ecological stress beginning with their migration to Hawai\u27i, and the potential outcomes of this stress (e.g., fighting, gangs, and drug use). Cultural buffers, such as traditional practices and culturally specific prevention programs, were described as aspects that prevented adverse outcomes. Implications for prevention practice are discussed

ZNF265—a novel spliceosomal protein able to induce alternative splicing

The formation of the active spliceosome, its recruitment to active areas of transcription, and its role in pre-mRNA splicing depends on the association of a number of multifunctional serine/arginine-rich (SR) proteins. ZNF265 is an arginine/serine-rich (RS) domain containing zinc finger protein with conserved pre-mRNA splicing protein motifs. Here we show that ZNF265 immunoprecipitates from splicing extracts in association with mRNA, and that it is able to alter splicing patterns of Tra2-β1 transcripts in a dose-dependent manner in HEK 293 cells. Yeast two-hybrid analysis and immunoprecipitation indicated interaction of ZNF265 with the essential splicing factor proteins U1-70K and U2AF35. Confocal microscopy demonstrated colocalization of ZNF265 with the motor neuron gene product SMN, the snRNP protein U1-70K, the SR protein SC35, and with the transcriptosomal components p300 and YY1. Transfection of HT-1080 cells with ZNF265–EGFP fusion constructs showed that nuclear localization of ZNF265 required the RS domain. Alignment with other RS domain–containing proteins revealed a high degree of SR dipeptide conservation. These data show that ZNF265 functions as a novel component of the mRNA processing machinery

Designs and Optical Tests of Thermal Links for an Optical Refrigerator

Dielectric mirror leakage at large angles of incidence limits the effectiveness of solid state optical refrigerators due to reheating caused by photon absorption in an attached load. In this paper, we present several thermally conductive link solutions to greatly reduce the net photon absorption. The Los Alamos Solid State Optical Refrigerator (LASSOR) has demonstrated cooling of a Yb/sup 3+/ doped ZBLANP glass to 208 K. We have designed optically isolating thermal link geometries capable of extending cooling to a typical heat load with minimal absorptive reheating, and we have tested the optical performance of these designs. A surrogate source operating at 625 nm was used to mimic the angular distribution of light from the LASSOR cooling element. While total link performance is dependent on additional factors, we have found that the best thermal link reduced the net transmission of photons to 0.04%, which includes the trapping mirrors 8.1% transmission. Our measurements of the optical performance of the various link geometries are supported by computer simulations of the designs using Code V, a commercially available optical modeling software package

Computer Modeling and Analysis of Thermal Link Performance for an Optical Refrigerator

We have used the thermal modeling tool in COMSOL Multiphysics to investigate factors that affect the thermal performance of the optical refrigerator. Assuming an ideal cooling element and a non-absorptive dielectric trapping mirror, the three dominant heating factors are blackbody radiation from the surrounding environment, conductive heat transfer through mechanical supports, and the absorption of fluorescent photons transmitted through the thermal link. Laboratory experimentation coupled with computer modeling using Code V optical software have resulted in link designs capable of reducing the transmission to 0.04% of the fluoresced photons emitted toward the thermal link. The ideal thermal link will have minimal surface area, provide complete optical isolation for the load, and possess high thermal conductivity. Modeling results imply that a 1 cm/sup 3/ load can be chilled to 102 K with currently available cooling efficiencies using a 100 W pump laser on a YB:ZBLANP system, and using an ideal link that has minimal surface area and no optical transmission. We review the simulated steady-state cooling temperatures reached by the heat load for several link designs and system configurations as a comparative measure of how well particular configurations perform

Diophantine approximation in Kleinian groups : singular, extremal, and bad limit points

The overall aim of this note is to initiate a ‘manifold’ theory for metric Diophantine approximation on the limit sets of Kleinian groups. We investigate the notions of singular and extremal limit points within the geometrically finite Kleinian group framework. Also, we consider the natural analogue of Davenport's problem regarding badly approximable limit points in a given subset of the limit set. Beyond extremality, we discuss potential Khintchine-type statements for subsets of the limit set. These can be interpreted as the conjectural ‘manifold’ strengthening of Sullivan's logarithmic law for geodesics

Thermal Links for the Implementation of an Optical Refrigerator

Optical refrigeration has been demonstrated by several groups of researchers, but the cooling elements have not been thermally linked to realistic heat loads in ways that achieve the desired temperatures. The ideal thermal link will have minimal surface area, provide complete optical isolation for the load, and possess high thermal conductivity. We have designed thermal links that minimize the absorption of fluoresced photons by the heat load using multiple mirrors and geometric shapes including a hemisphere, a kinked waveguide, and a tapered waveguide. While total link performance is dependent on additional factors, we have observed net transmission of photons with the tapered link as low as 0.04%. Our optical tests have been performed with a surrogate source that operates at 625 nm and mimics the angular distribution of light emitted from the cooling element of the Los Alamos solid state optical refrigerator. We have confirmed the optical performance of our various link geometries with computer simulations using CODE V optical modeling software. In addition we have used the thermal modeling tool in COMSOL MULTIPHYSICS to investigate other heating factors that affect the thermal performance of the optical refrigerator. Assuming an ideal cooling element and a nonabsorptive dielectric trapping mirror, the three dominant heating factors are (1) absorption of fluoresced photons transmitted through the thermal link, (2) blackbody radiation from the surrounding environment, and (3) conductive heat transfer through mechanical supports. Modeling results show that a 1 cm3 load can be chilled to 107 K with a 100Wpump laser. We have used the simulated steady-state cooling temperatures of the heat load to compare link designs and system configurations

Emerging roles of hnRNPA1 inmodulating malignanttransformation

Heterogeneous nuclear ribonucleoproteins (hnRNPs) are RNA-binding proteins associated with complex and diverse biological processes such as processing of heterogeneous nuclear RNAs (hnRNAs) into mature mRNAs, RNA splicing, transactivation of gene expression, and modulation of protein translation. hnRNPA1 is the most abundant and ubiquitously expressed member of this protein family and has been shown to be involved in multiple molecular events driving malignant transformation. In addition to selective mRNA splicing events promoting expression of specific protein variants, hnRNPA1 regulates the gene expression and translation of several key players associated with tumorigenesis and cancer progression. Here, we will summarize our current knowledge of the involvement of hnRNPA1 in cancer, including its roles in regulating cell proliferation, invasiveness, metabolism, adaptation to stress and immortalization
