The activity of the feminist online publications: challenges for the transmission of the feminist culture in Spain

Traditionally, big media corporations have contributed to hiding the women’s movement itself, as well as its main claims and topics of discussion (Marx, Myra y Hess, 1995; Rhode, 1995; Mendes, 2011). This has led the feminist movement to develop its own media generally print publications, usually, with a very specialized character and reduced audience. This is similar to what has occurred with quality main stream media, asthese publications have had to adapt themselves to a new communicatiion context, because of the financial crisis and  technological evolution. Feminist media has found in the Internet an excellent opportunity to access citizens and communicate their messages. , In view of this scene of change and renovation,  this article offers the results of a qualitative analysis focused on the experiences of four feminist online media sites edited in Spain: Pikaramagazine.com, Proyecto-kahlo.com, Mujeresenred.net and Laindependent.cat. Besides exploring the characteristics and content of these sites, the article pays attention to the virality of their contents spread through Facebook and Twitter. The onclusion estimates their social impact, insofar as they symbolize the specialization, diversification and dialogue promoted by the Web.

Endothelial cell-derived Pentraxin 3 limits the vasoreparative therapeutic potential of Circulating Angiogenic Cells

AIMS: Circulating Angiogenic Cells (CACs) promote revascularization of ischemic tissues although their underlying mechanism of action and the consequences of delivering varying numbers of these cells for therapy remain unknown. This study investigates molecular mechanisms underpinning CAC modulation of blood vessel formation.

METHODS & RESULTS: CACs at low (2x10(5)cells/ml) and mid (2x10(6)cells/ml) cellular densities significantly enhanced endothelial cell (EC) tube formation in vitro, while high density CACs (2x10(7)cells/ml) significantly inhibited this angiogenic process. In vivo, Matrigel-based angiogenesis assays confirmed mid-density CACs as pro-angiogenic and high density CACs as anti-angiogenic. Secretome characterization of CAC-EC conditioned media identified pentraxin 3 (PTX3) as only present in the high density CAC-EC co-culture. Recombinant PTX3 inhibited endothelial tube formation in vitro and in vivo Importantly, our data revealed that the anti-angiogenic effect observed in high density CAC-EC co-cultures was significantly abrogated when PTX3 bioactivity was blocked using neutralizing antibodies or PTX3 siRNA in endothelial cells. We show evidence for an endothelial source of PTX3, triggered by exposure to high density CACs. In addition, we confirmed that PTX3 inhibits FGF2-mediated angiogenesis, and that the PTX3 N-terminus, containing the FGF-binding site, is responsible for such anti-angiogenic effects.

CONCLUSIONS: Endothelium, when exposed to high density CACs, releases PTX3 which markedly impairs the vascular regenerative response in an autocrine manner. Therefore, CAC density and accompanying release of angiocrine PTX3 are critical considerations when using these cells as a cell therapy for ischemic disease.

Vaisseau sanguin reconstruit par génie tissulaire : Développement d'une nouvelle approche pour la reconstruction de la media et interaction avec les microparticules

La media vasculaire est au coeur des processus physiopathologiques qui entraînent le développement de l’athérosclérose. L’utilisation d’une media reconstruite par génie tissulaire permet d’étudier les cellules musculaires lisses (CML) humaines dans un environnement plus physiologique que les cellules en culture monocouche. Les travaux présentés dans cette thèse sont orientés autour de la media vasculaire reconstruite par génie tissulaire comme modèle d’étude pharmacologique et prothèse vasculaire autologue. La première partie des travaux porte sur l’étude des interactions de cette tunique avec les microparticules (MP) circulantes. D’abord, nous avons montré que la présence de l’adventice modifie la réponse de la media aux MP produites in vitro à partir des lymphocytes T. Ensuite, l’étude de l’effet des MP isolées du sérum de patients en choc septique sur la media humaine a démontré que ces MP sont en mesure d’augmenter la contraction de la media par un mécanisme impliquant une diminution du NO et une augmentation de l’expression de l’ARN messager de l’interleukine-10. L’incubation de la media reconstruite avec cette cytokine anti-inflammatoire bloque l’hyporéactivité induite par les lipopolysaccharides. Le même phénomène a été reproduit in vivo, chez le rongeur. Ces résultats suggèrent que les SMP auraient un effet protecteur sur la fonction vasculaire, en potentialisant la contraction de la media. Ensuite, nous avons optimisé l’approche de reconstruction de prothèses vasculaires par auto-assemblage proposée initialement pour l’adapter au contexte particulier des CML. L’objectif principal était de permettre l’étude physiopathologique de la media à partir de toutes les lignées de CML; indépendamment de leur capacité de synthèse de matrice extracellulaire. Pour ce faire, nous avons développé un échafaudage de matrice extracellulaire produit par auto-assemblage à partir de fibroblastes humains. L’utilisation de cet échafaudage génère une media plus résistante et plus contractile que la technique initiale. Enfin, une anisotropie a été créée dans cet échafaudage pour permettre une orientation physiologique des CML. La media reconstruite devient ainsi plus résistante et plus contractile. Ces améliorations permettent de reconstruire des media à partir des cellules de plus de patients et mèneront à des études pharmacologiques plus représentatives de la population. Cet échafaudage facilitera la translation clinique de ce modèle de media reconstruite par génie tissulaire.

You play your part – participatory media and older women.

This chapter will examine participatory and collaborative production strategies that create opportunities for older women to participate in media production. It draws on practice-led research in participatory and community-based media in the Govan area of Glasgow, Scotland. In particular, it examines the production process of a participatory documentary I produced and directed with senior citizens who are members of the Govan Seniors Film Club, based at the Portal Arts Centre in Govan.You Play Your Part is a 20-minute documentary about campaigning women in and around Govan.

Tourism Media Dynamics: Narratives of the Nation-State

With the premise that the tourism promotional video “China, Forever” provides a crucial access to understanding how tourism engages in a wider circle of socio-culture formation, this dissertation research approaches tourism by examining communicative practices initiated by “China, Forever”. In doing so, it seeks to reveal two dialogues – firstly, between the discursive construction of tourism representational language and China’s nation-state ideology; secondly, between interpretations from overseas Chinese audiences and nation-state narratives delivered via the tourism media. In analyzing the first dialogue, this dissertation reveals that the pursuit of collective and monolithic national imagery has caused a representational violence – one that is committed by the nation-state ideology operated through the organization of tourism language. The very representational coercion itself, however, signifies the nature of tourism media as a vehicle mediating the global gaze and China’s self-representation; illuminating the fact that China’s nation-state building is only to be understood as deeply-grounded in the complexity of postcolonial politics. Furthermore, in a dialectic view, such finding consolidates the nature of “China, Forever” as a cultural product that actively exists as a component in the overall social fabric, co-creating a wider circle of culture politics together with other genres of media products; thus, calling for a more comprehensive understanding of tourism media at large. In the second approach, this dissertation seeks to understand how the tourism video “China, Forever” mediates the relationship between tourism narratives of the nation-state and overseas Chinese individuals; thus bridging together tourism media and ongoing life experiences of the audiences chosen. The analysis reveals that audiences’ interpretations heavily concentrate on resisting and fragmenting the hegemonic nation-state language in “China, Forever”. While some interviewees seek to decentralize the nation-state perspective from aspects of aesthetics, representational style, and representational subjects in “China, Forever” by incorporating their individual memories and past experiences, to some others, the over-polished glorification of China in the mediated tourism discourse is only coercive to China’s social realities experienced by the individual interviewees - the disheartening contrasts of poverty and affluence as well as other social inequalities. From the perspective of the audience group, the Chinese scholars and students at the University of Illinois interviewed for this dissertation research constitute a cohort of exiled audiences for the tourism video “China, Forever”. The audiences subject themselves to voluntary interpellation, a process in which they find themselves defending, negotiating, and resisting the nation-state representation of China – even though they are not its intended audience and have had no input into its production. Nevertheless, such process is one of identification, in which viewers articulate a subject position from which to speak of their own experiences, dilemmas and desires. The usefulness of tourism media discourse in mediating the nation-state narratives and the individual experience is amplified.

Viral Bodies: Uncontrollable Blackness in Popular Culture and Everyday Life

Viral Bodies: Uncontrollable Blackness in Popular Culture and Everyday Life maps rapidly circulated performances of Blackness across visual media that collapse Black bodies into ubiquitous “things.” Throughout my dissertation, I use viral performance to describe the uncontrollable discursive circulation of bodies, their behaviors, and the ideas around them. In particular, viral performance is employed to describe the complicated ways that (mis)understandings of Black bodies spread and are often transformed into common-sense beliefs. As viral performances, Black bodies are often made more visible, while simultaneously becoming more opaque. This dissertation examines the recurrence of viral performances of Blackness in viral videos online, film, and photography/images. I argue that viral performances make products that reinscribe stereotypical notions of Blackness while also generating paths of alterity—which contradict the normalized clichés and provide desirable possibilities for Black performance. Viral Bodies forges a new dialogue between visual and aural technologies, performance, and larger historic discourses that script Black bodies as visually (and sonically) deviant subjects. I am interested in how technologies complicate the re-presentation of images, ideas, and ideologies—producing a necessity for new decipherings of performances of Blackness in popular culture and everyday life.

How valuable is web 2.0 to music criticism? An investigation into the role of web 2.0 and social media in the reception of Benjamin Britten's operas

The internet is deeply integrated with many people's day to day lives, including that of musicians and musicologists. In this thesis, the impact of the internet on classical music criticism in the Web 2.0 age is examined. Using the examples of Britten's operas, Gloriana and Peter Grimes, an overview of their critical reception is examined, using printed reviews found in The Times since their premières, internet based reviews of two specific performances, and the reactions to these performances on Twitter. Theories of media behaviour including de Mul's view of the 'ludic self' are used in order to explain the content found in reviews in conjunction with citizen journalism, of which blogging is an extension. While there are some consistencies between the print reviews and those online, there are stylistic differences, and wider repercussions for the world of criticism in the wake of the democratisation of culture, as critics find their previously regarded authority obsolete to some. Music criticism is no longer the reserve of the musicologists

Cultural citizenship and its implications for citizenship education: Chinese university students’ civic experience in relation to mass media and the university citizenship curriculum

A growing body of research has argued that university citizenship curricula are inefficient in promoting civic participation, while there is a tendency towards a broader citizenship understanding and new forms of civic engagements and citizenship learning in everyday life. The notion of cultural citizenship in this thesis concentrates on media practices’ relation to civic expression and civic engagement. This research thus argues that not enough attention has been paid to the effects of citizenship education policy on students and students’ active citizenship learning in China. This thesis examines the civic experience of university students in China in the parallel contexts of widespread adoption of mass media and of university citizenship education courses, which have been explicitly mandatory for promoting civic morality education in Chinese universities since 2007. This research project raises significant questions about the meditating influences of these two contexts on students’ perceptions of civic knowledge and civic participation, with particular interest to examine whether and how the notion of cultural citizenship could be applied in the Chinese context and whether it could provide certain implications for citizenship education in China. University students in one university in Beijing contributed to this research by providing both quantitative and qualitative data collected from mixed-methods research. 212 participants contributed to the questionnaire data collection and 12 students took part in interviews. Guided by the theoretical framework of cultural citizenship, a central focus of this study is to explore whether new forms of civic engagement and civic learning and a new direction of citizenship understanding can be identified among university students’ mass media use. The study examines the patterns of students’ mass media use and its relationship to civic participation, and also explores the ways in which mass media shape students and how they interact and perform through the media use. In addition, this study discusses questions about how national context, citizenship tradition and civic education curricula relate to students’ civic perceptions, civic participation and civic motivation in their enactment of cultural citizenship. It thus tries to provide insights and identify problems associated with citizenship courses in Chinese universities. The research finds that Chinese university students can also identify civic issues and engage in civic participation through the influence of mass media, thus indicating the application of cultural citizenship in the wider higher education arena in China. In particular, the findings demonstrate that students’ citizenship knowledge has been influenced by their entertainment experiences with TV programs, social networks and movies. However, the study argues that the full enactment of cultural citizenship in China is conditional with regards to characteristics related to two prerequisites: the quality of participation and the influence of the public sphere in the Chinese context. Most students in the study are found to be inactive civic participants in their everyday lives, especially in political participation. Students express their willingness to take part in civic activities, but they feel constrained by both the current citizenship education curriculum in universities and the strict national policy framework. They mainly choose to accept ideological and political education for the sake of personal development rather than to actively resist it, however, they employ creative ways online to express civic opinions and conduct civic discussion. This can be conceptualised as the cultural dimension of citizenship observed from students who are not passively prescribed by traditional citizenship but who have opportunities to build their own civic understanding in everyday life. These findings lead to the conclusion that the notion of cultural citizenship not only provides a new mode of civic learning for Chinese students but also offers a new direction for configuring citizenship in China. This study enriches the existing global literature on cultural citizenship by providing contemporary evidence from China which is a developing democratic country, as well as offering useful information for Chinese university practitioners, policy makers and citizenship researchers on possible directions for citizenship understanding and citizenship education. In particular, it indicates that it is important for efforts to be made to generate a culture of authentic civic participation for students in the university as well as to promote the development of the public sphere in the community and the country generally.

Character, Audience Agency and Trans-Media Drama

Changes in the television industry with regards to the development of new media technologies are having a significant impact on audience engagement with television drama. This article explores how the internet is being used to extend audience engagement onto platforms other than the television set to the point where television drama should increasingly be reconsidered as trans-media drama. However audience engagement with the various elements of a trans-media drama text is complex. By exploring audience attitudes towards character in the British television series Spooks and its associated online games, this article argues that in an increasingly converged media landscape audiences transfer values between platforms. Consequently the audience's perception of control in relation to their engagement with a trans-media drama text such as Spooks becomes complicated with values associated with television proving key to their engagement with the same fictional world in the form of games.

Utilisation d’un modèle de co-culture cellulaire pour l’évaluation in vitro du transport inverse du cholestérol

De nouveaux modèles cellulaires in vitro par transfert de milieu et par coculture ont été mis au point afin d’évaluer la capacité des HDL à éliminer l’excès de cholestérol des tissus périphériques et de le transporter vers le foie afin d’être excrété par le foie, un processus nommé le transport inverse du cholestérol (TIC). Le système cellulaire par transfert in vitro où des macrophages J774 sont gorgés de LDL acétylées et marqués au 3H-cholestérol a été préalablement établi afin de mesurer par scintillation l’efflux de cholestérol marqué vers le milieu de culture contenant des accepteurs de cholestérol. Ce milieu conditionné est transféré sur des cellules HepG2 afin d’étudier l’influx du cholestérol marqué. Ce dernier nous permet d’observer un transport de cholestérol de 25 % hors des J774 et un transport de 39 000 cpm dans les HepG2 en utilisant un milieu contenant 2 % de sérums humains mis en commun. Une stimulation des cellules J774 par l’AMPc augmente l’efflux et l’influx d’environ 45 %. Des tests de preuve de concept ont été effectués sur le système cellulaire par co-culture qui utilise des chambres de Boyden où les J774 sont localisées au fond d’un puits et les HepG2 dans un insert, et où le milieu est partagé entre les deux types cellulaires. On a déterminé qu’une confluence densité de 60 000 cellules/cm2 sur un insert constitué d’une membrane de polyester avec des pores de 3,0 μm, sans autre revêtement, permet d’observer un influx spécifique au sérum d’environ 6 000 cpm associés aux cellules HepG2, où 50 % des comptes radioactifs sont dans les cellules et l’autre moitié présente à la surface cellulaire.

MEDIA IN THE ERA OF GLOBALIZATION IN LATIN AMERICA

Terms like Internet, cyberspace, virtual reality, in short, globalization, have been frequently words for all of us, in recent years. This refers to the phenomenon that has shaken the people of this world. Are rapidly changing due to technological advances and complex levels reaching relations between countries, corporations, partnerships and people.The attempt to understand the phenomenon of globalization is compounded when we try to understand the term, coined by Marshall McLuhan.McLuhan was born in Edmonton, Alberta, Canada and studied at the Universities of Manitoba and Cambridge, the latter of which he received his degree of Doctor of Philosophy specializing in English Literature. He taught at the universities of Wisconsin and St. Louis and University of the Assumption and Saint Michael's College, University of Toronto, where he was director of the Center for Culture and Technology.Marshall McLuhan and B. R. Powers, wrote the play, The Village Global1. The universe has become a village is the future predicted for them in the 60's. Today reality has overtaken the theory. However, this phenomenon is presented in this work, so whimsical style reminiscent of Jules Verne, but does not clarify the content of the term. While we believe that in the past there were attempts; globalize these attempts were very different from what we understand by globalization. 

Screening Diversity: Women & Work in Twenty-First-Century Popular Culture

Screening Diversity: Women and Work in Twenty-first Century Popular Culture explores contemporary representations of diverse professional women on screen. Audiences are offered successful women with limited concerns for feminism, anti-racism, or economic justice. I introduce the term viewsers to describe a group of movie and television viewers in the context of the online review platform Internet Movie Database (IMDb) and the social media platforms Twitter and Facebook. Screening Diversity follows their engagement in a representative sample of professional women on film and television produced between 2007 and 2015. The sample includes the television shows, Scandal, Homeland, VEEP, Parks and Recreation, and The Good Wife, as well as the movies, Zero Dark Thirty, The Proposal, The Heat, The Other Woman, I Don’t Know How She Does It, and Temptation. Viewsers appreciated female characters like Olivia (Scandal), and Maya (Zero Dark Thiry) who treated their work as a quasi-religious moral imperative. Producers and viewsers shared the belief that unlimited time commitment and personal identification were vital components of professionalism. However, powerful women, like The Proposal’s Margaret and VEEP’s Selina, were often called bitches. Some viewsers embraced bitch-positive politics in recognition of the struggles of women in power. Women’s disproportionate responsibility for reproductive labor, often compromises their ability to live up to moral standards of work. Unlike producers, viewsers celebrated and valued that labor. However, texts that included serious consideration of women as workers were frequently labelled chick flicks or soap operas. The label suggested that women’s labor issues were not important enough that they could be a topic of quality television or prestigious film, which bolstered the idea that workplace equality for women is not a problem in which the general public is implicated. Emerging discussions of racial injustice on television offered hope that these formations are beginning to shift.

Los derechos sobre la tierra en el sector centro-oriental de la Extremadura castellana. Usos y abusos a fines de la Edad Media

El régimen de propiedad y los derechos y usos de la tierra se encontraban, a fines del período medieval, directamente condicionados por las circunstancias físicas, pero también, y sobre todo, por la superposición de los intereses de los distintos sectores sociales. La situación se presentaba especialmente compleja en aquellos territorios de tradicional explotación comunitaria, donde el proceso de diferenciación social, con la consolidación de una oligarquía urbana, la presencia del campesinado, y de un sector enriquecido en el mismo, y la implantación de una poderosa nobleza señorial, determinó un panorama de imprecisión y multiplicación de los derechos sobre la tierra, en medio de fuertes tensiones. El caso de Cuenca, en el sector centro-oriental de la Extremadura castellana, presenta particular interés, y constituye un escenario muy adecuado para observar los procesos por los que la propiedad particular y los usos privatizados se abrieron paso, produciendo la ruptura del sistema de organización comunal.
