This paper is a literature review of articles published from 1992 to 2002 in the American Journal of Health Education using critical race theory as a lens of analysis of culture differences in healthcare.

American Teachers in Anti-American Environments: How to Incorporate “Culture” in the EFL Classroom

This paper explores the facets and the importance of culture as a necessary context for language competency, acknowledges the relevance of an antipathy towards Americanization, and investigates the characteristics of successful pedagogy for American teachers in a global setting of turbulent geopolitical circumstances influencing the EFL environment.

The performance of high -ability Black upper elementary grade students in an International Baccalaureate program

The purpose of this study was to investigate the common factors and experiences that contribute to the success of high ability Black students enrolled in Frank C. Martin Elementary School, the first school in Florida authorized to offer the International Baccalaureate (IB) Primary Years Programme (PYP). The study further sought to determine ways in which educators and stakeholders assisted in maintaining and in increasing Black students' achievement that motivated and encouraged them to pursue similar programs at the middle and high school levels. ^ Three sources of data were used: (a) individual interviews with fourth and fifth grade high ability Black students using a semi-structured format elicited discussion of their perceptions of the PYP and factors contributing to their success; (b) individual interviews with their fourth and fifth grade teachers elicited discussion of teacher expectations and effective instructional strategies; and (c) a questionnaire asked parents of the participating students their reasons for choosing the PYP, their perceptions of the program, and their own level of involvement in their child's learning. Three separate focus groups gathered further data. ^ The results revealed that the factors contributing to the success of high ability Black elementary school students are consistent with those of students in other racial groups. These are a challenging program, high teacher and parental expectations, strong parental involvement and support, a celebration of culture and diversity in a caring and nurturing environment, and the development and internalization of positive attitudes. ^ Implications for future studies might include a longitudinal study conducted over seven years to trace the achievements of Black students throughout the entire IB Program. ^

The Experience of “Bottoming”: Considerations for Identity and Learning

Bottoms—Gay men who prefer to be penetrated, sexually—are more stigmatized than other gay men, and may develop and experience identities differently than other gay, bisexual, or heterosexual men. This paper explores intrinsic dispositions and extrinsic motivations that may lead bottoms to perform and embody psychosocial and sexual identities in intimate, interpersonal, and social contexts.

Enhanced anchorage of tissue-engineered cartilage using an osteoinductive approach

Articular cartilage injuries occur frequently in the knee joint. Several methods have been implemented clinically, to treat osteochondral defects but none have been able to produce a long term, durable solution. Photopolymerizable cartilage tissue engineering approaches appear promising; however, fundamentally, forming a stable interface between the tissue engineered cartilage and native tissue, mainly subchondral bone and native cartilage, remains a major challenge. The overall objective of this research is to find a solution for the current problem of dislodgment of tissue engineered cartilage at the defect site for the treatment of degraded cartilage that has been caused due to knee injuries or because of mild to moderate level of osteoarthritis. For this, an in-vitro model was created to analyze the integration of tissue engineered cartilage with the bone, healthy and diseased cartilage over time. We investigated the utility of hydroxyapatite (HA) nanoparticles to promote controlled bone-growth across the bone-cartilage interface in an in vitro engineered tissue model system using bone marrow derived stem cells. We also investigated the application of HA nanoparticles to promote enhance integration between tissue engineered cartilage and native cartilage both in healthy and diseased states. Samples incorporated with HA demonstrated significantly higher interfacial shear strength (at the junction between engineered cartilage and engineered bone and also with diseased cartilage) compared to the constructs without HA (p < 0.05), after 28 days of culture. These findings indicate that the incorporation of HA nanoparticles permits more stable anchorage of the injectable hydrogel-based engineered cartilage construct via augmented integration between bone and cartilage.^

Pioneers in the study of motion

From the multitudinous streets of Mexico City through the lonely highways of the United States, this collection of poetry charts strategies of representation across complex territories of culture and gender. These poems represent dialogues and negotiations with popular and poetic narratives of the Americas, as well as individual quests for identification against a backdrop of postmodern and postcolonial concerns. The effect is like that of a collage that elicits the reader's participation in order to produce individual signification. The figures alluded to in these pieces enact the struggle to situate the self within multiple registers of discourse and identity, as well as to establish a site from which to speak.

Les référendums sur la souveraineté de l'Écosse et de la Catalogne : le renvoi relatif à la sécession du Québec en comparaison

L’année 2014 est marquée par les référendums sur la souveraineté de l’Écosse et de la Catalogne, deux nations partageant de nombreux points communs sur les plans de l’histoire et de la culture. Le cadre juridique pré-référendaire de chacune de ces régions est fondamentalement le même: l’existence juridique de l’Écosse et de la Catalogne est directement issue de la volonté d’un État central unitaire, respectivement le Royaume-Uni et l’Espagne. La compétence législative de tenir un référendum sur l’autodétermination de ces régions est d’ailleurs ambiguë. Devant ce dilemme, le Royaume-Uni permet à l’Écosse d’organiser un référendum sur sa souveraineté. Il en résulte un processus démocratique juste, équitable, décisif et respecté de tous. De son côté, l’Espagne interdit à la Catalogne d’en faire de même, ce qui n’empêche pas Barcelone de tout mettre en œuvre afin de consulter sa population. Il en découle un processus de participation citoyenne n’ayant rien à voir avec un référendum en bonne et due forme. 20 ans après le dernier référendum sur la souveraineté du Québec, l’étude des référendums de l’Écosse et de la Catalogne nous permet de mettre en lumière la justesse, mais aussi l’incohérence partielle des enseignements de la Cour suprême du Canada dans son Renvoi relatif à la sécession du Québec. D’un côté, la nécessité d’équilibrer les principes constitutionnels sous-jacents de démocratie et de constitutionnalisme est mise en exergue. Parallèlement, les concepts de question et de réponse claires, d’effectivité et de négociations post-référendaires prennent une toute autre couleur face à un nouvel impératif absent des conclusions de la Cour suprême : celui des négociations pré-référendaires.

Combined Gene Therapy and Functional Tissue Engineering for the Treatment of Osteoarthritis

The pathogenesis of osteoarthritis is mediated in part by inflammatory cytokines including interleukin-1 (IL-1), which promote degradation of articular cartilage and prevent human mesenchymal stem cell (hMSC) chondrogenesis. We combined gene therapy and functional tissue engineering to develop engineered cartilage with immunomodulatory properties that allow chondrogenesis in the presence of pathologic levels of IL-1 by inducing overexpression of IL-1 receptor antagonist (IL-1Ra) in hMSCs via scaffold-mediated lentiviral gene delivery. A doxycycline-inducible vector was used to transduce hMSCs in monolayer or within 3D woven PCL scaffolds to enable tunable IL-1Ra production. In the presence of IL-1, IL-1Ra-expressing engineered cartilage produced cartilage-specific extracellular matrix, while resisting IL-1-induced upregulation of matrix metalloproteinases and maintaining mechanical properties similar to native articular cartilage. The ability of functional engineered cartilage to deliver tunable anti-inflammatory cytokines to the joint may enhance the long-term success of therapies for cartilage injuries or osteoarthritis.

Following this, we modified this anti-inflammatory engineered cartilage to incorporate rabbit MSCs and evaluated this therapeutic strategy in a pilot study in vivo in rabbit osteochondral defects. Rabbits were fed a custom doxycycline diet to induce gene expression in engineered cartilage implanted in the joint. Serum and synovial fluid were collected and the levels of doxycycline and inflammatory mediators were measured. Rabbits were euthanized 3 weeks following surgery and tissues were harvested for analysis. We found that doxycycline levels in serum and synovial fluid were too low to induce strong overexpression of hIL-1Ra in the joint and hIL-1Ra was undetectable in synovial fluid via ELISA. Although hIL-1Ra expression in the first few days local to the site of injury may have had a beneficial effect, overall a higher doxycycline dose and more readily transduced cell population would improve application of this therapy.

In addition to the 3D woven PCL scaffold, cartilage-derived matrix scaffolds have recently emerged as a promising option for cartilage tissue engineering. Spatially-defined, biomaterial-mediated lentiviral gene delivery of tunable and inducible morphogenetic transgenes may enable guided differentiation of hMSCs into both cartilage and bone within CDM scaffolds, enhancing the ability of the CDM scaffold to provide chondrogenic cues to hMSCs. In addition to controlled production of anti-inflammatory proteins within the joint, in situ production of chondro- and osteo-inductive factors within tissue-engineered cartilage, bone, or osteochondral tissue may be highly advantageous as it could eliminate the need for extensive in vitro differentiation involving supplementation of culture media with exogenous growth factors. To this end, we have utilized controlled overexpression of transforming growth factor-beta 3 (TGF-β3), bone morphogenetic protein-2 (BMP-2) or a combination of both factors, to induce chondrogenesis, osteogenesis, or both, within CDM hemispheres. We found that TGF-β3 overexpression led to robust chondrogenesis in vitro and BMP-2 overexpression led to mineralization but not accumulation of type I collagen. We also showed the development of a single osteochondral construct by combining tissues overexpressing BMP-2 (hemisphere insert) and TGF-β3 (hollow hemisphere shell) and culturing them together in the same media. Chondrogenic ECM was localized in the TGF-β3-expressing portion and osteogenic ECM was localized in the BMP-2-expressing region. Tissue also formed in the interface between the two pieces, integrating them into a single construct.

Since CDM scaffolds can be enzymatically degraded just like native cartilage, we hypothesized that IL-1 may have an even larger influence on CDM than PCL tissue-engineered constructs. Additionally, anti-inflammatory engineered cartilage implanted in vivo will likely affect cartilage and the underlying bone. There is some evidence that osteogenesis may be enhanced by IL-1 treatment rather than inhibited. To investigate the effects of an inflammatory environment on osteogenesis and chondrogenesis within CDM hemispheres, we evaluated the ability of IL-1Ra-expressing or control constructs to undergo chondrogenesis and osteogenesis in the prescence of IL-1. We found that IL-1 prevented chondrogenesis in CDM hemispheres but did not did not produce discernable effects on osteogenesis in CDM hemispheres. IL-1Ra-expressing CDM hemispheres produced robust cartilage-like ECM and did not upregulate inflammatory mediators during chondrogenic culture in the presence of IL-1.

Seawater carbonate chemistry and biological processes of Emiliania huxleyi (PML B92/11) during experiments, 2011

The present study investigates the combined effect of phosphorous limitation, elevated partial pressure of CO2 (pCO2) and temperature on a calcifying strain of Emiliania huxleyi (PML B92/11) by means of a fully controlled continuous culture facility. Two levels of phosphorous limitation were consecutively applied by renewal of culture media (N:P = 26) at dilution rates (D) of 0.3 d- and 0.1 d-1. CO2 and temperature conditions were 300, 550 and 900 µatm pCO2 at 14 °C and 900 µatm pCO2 at 18 °C. In general, the steady state cell density and particulate organic carbon (POC) production increased with pCO2, yielding significantly higher concentrations in cultures grown at 900 µatm pCO2 compared to 300 and 550 µatm pCO2. At 900 µatm pCO2, elevation of temperature as expected for a greenhouse ocean, further increased cell densities and POC concentrations. In contrast to POC concentration, C-quotas (pmol C cell-1) were similar at D = 0.3 d-1 in all cultures. At D = 0.1 d-1, a reduction of C-quotas by up to 15% was observed in the 900 µatm pCO2 at 18 °C culture. As a result of growth rate reduction, POC:PON:POP ratios deviated strongly from the Redfield ratio, primarily due to an increase in POC. Ratios of particulate inorganic and organic carbon (PIC:POC) ranged from 0.14 to 0.18 at D = 0.3 d-1, and from 0.11 to 0.17 at D = 0.1 d-1, with variations primarily induced by the changes in POC. At D = 0.1 d-1, cell volume was reduced by up to 22% in cultures grown at 900 µatm pCO2. Our results indicate that changes in pCO2, temperature and phosphorus supply affect cell density, POC concentration and size of E. huxleyi (PML B92/11) to varying degrees, and will likely impact bloom development as well as biogeochemical cycling in a greenhouse ocean.

Active energy - London: capital / climate / culture

As negotiators and the media descended on Paris, the Festival explored how culture in London interacts with the climate crisis through bringing together artists, journalists, politicians and academics to debate London’s role as a city of fossil fuels, and the responsibility of culture to drive a rupture with business as usual. The Active Energy project provided an example of how older citizens are able to draw on their extensive life experience to help counter climate crisis, and the role of the arts in facilitating that process.

Policy Solutions and International Perspectives on the Funding of Public Service Media Content for Children: A Report for Stakeholders

This project on Policy Solutions and International Perspectives on the Funding of Public Service Media Content for Children began on 8 February 2016 and concludes on 31 May 2016. Its outcomes contribute to the policy-making process around BBC Charter Review, which has raised concerns about the financial sustainability of UK-produced children’s screen content. The aim of this project is to evaluate different funding possibilities for public service children’s content in a more challenging and competitive multiplatform media environment, drawing on experiences outside the UK. The project addresses the following questions: • What forms of alternative funding exist to support public service content for children in a transforming multiplatform media environment? • What can we learn from the types of funding and support for children’s screen content that are available elsewhere in the world – in terms of regulatory foundations, administration, accountability, levels of funding, amounts and types of content supported? • How effective are these funding systems and funding sources for supporting domestically produced content (range and numbers of projects supported; audience reach)? This stakeholder report constitutes the main outcome of the project and provides an overview and analysis of alternatives for supporting and funding home-grown children’s screen content across both traditional broadcasting outlets and emerging digital platforms. The report has been made publicly available, so that it can inform policy work and responses to the UK Government White Paper, A BBC for the Future, published by the Department of Culture, Media and Sport in May 2016.

The Art of the State

When we talk of culture we are talking about a source of enormous historical social power. Why did the GLC commitment to Popular Culture upset the rules of the unelected arts and sports quangos? How did the now abolished GLC get politics into arts policy?

Influences and advice of theatrical consumption. A study about the effect of the theatre critics and other instances of evaluation in the habits of theatre attendance

This article analyses the influence that different criticism stages of proceedings exert in the habits of theatre attendance. The study is based on the survey carried out specifically for this research in which 210 people, who attended a theatrical representation, were interviewed in three different theatres in the city of Valencia. The study has revealed the mouth to mouth importance in the decision of attending the theatre and its stronger influence on the audiences who less frequently go to theatrical representations. The results obtained have also made clear the existence of a narrow relation between the advice effect of the theatre critics and the patterns of attendance to the theatre, just like its bigger influence between theatres with commercial orientation and those which are addressed to the broad audiences.

Travel, back and forth, to the myth. Cinema´s contribution to the formation of the tourist iconography of Mallorca

Mallorca, the largest of the Balearic Islands, is a well-known summer holidays destination; an ideal place to relax and enjoy the sun and the sea. That tourist gaze reflected on postcards results from advertising campaigns, where cinema played an important role with documentaries and fiction films. The origins of that iconography started in the decades of the 1920’s and 1930’s, reflecting the so-called myth of the “island of calm”. On the other hand, the films of the 1950’s and 1960’s created new stereotypes related to the mass tourism boom. Busy beaches and the white bodies of tourists replaced white sandy beaches, mountains and landscapes shown up in the movies of the early decades of the 20th century. Besides, hotels and nightclubs also replaced monuments, rural landscapes and folk exhibitions. These tourist images mirror the social and spatial transformations of Mallorca, under standardization processes like other seaside mass tourist destinations. The identity was rebuilt on the foundations of "modernity". Although "balearization" has not ceased, nowadays filmmaking about Mallorca is advertising again a stereotype close to that one of the 1920s and 1930s, glorifying the myth of the "island of calm". This singular identity makes the island more profitable for capital that searches socio-spatial differentiation in post-fordist times.
