El cambio que rima. Creando espacios alternativos de contestación cultural desde el hip hop. Estudio del caso de raperos de El Alto y La Paz

A través de este trabajo se pretende comprender cómo se construye un espacio de contestación cultural y político desde una expresión artística como rap, que para aquellos que son sus seguidores, es parte de la “cultura Hip Hop”. Para cumplir este objetivo, el presente estudio desarrolla en el primer capítulo una recapitulación metodológica del camino trazado, es decir la explicación de las técnicas, herramientas y enfoques desde los que se trataron el tema, y por qué éstas se eligieron. En el segundo capítulo se da una breve reseña sobre el movimiento de rap a nivel mundial y nacional para luego concretar el desarrollo del movimiento en La Paz y El Alto. Finalmente, el tercer capítulo pretende mostrar el camino que une a los raperos con el público. Este es el eje del último capítulo, pues a través del presente documento, se plantea la relación entre músicos, activistas o artistas, con un público determinado. Esta tesis es una forma de entender cómo jóvenes de distinta procedencia y visiones sobre la vida, actúan en su sociedad y hablan de su realidad creando espacios de contestación que interpelan y responden a hechos concretos que afectan su cotidianeidad.

Proteomic analysis of resting and thrombin-stimulated platelets reveals the translocation and functional relevance of HIP-55 in platelets

The platelet surface is a dynamic interface that changes rapidly in response to stimuli to coordinate the formation of thrombi at sites of vascular injury. Tight control is essential as loss of organisation may result in the inappropriate formation of thrombi (thrombosis) or excessive bleeding. In this paper we describe the comparative analysis of resting and thrombin-stimulated platelet membrane proteomes and associated proteins to identify proteins important to platelet function. Surface proteins were labelled using a biotin tag and isolated by NeurtrAvidin affinity chromatography. Liquid phase IEF and SDS-PAGE were used to separate proteins, and bands of increased intensity in the stimulated platelet fractions were digested and identified by FT-ICR mass spectrometry. Novel proteins were identified along with proteins known to be translocated to the platelet surface. Furthermore, many platelet proteins revealed changes in location associated with function, including G6B and Hip-55. HIP-55 is an SH3-binding protein important in T-cell receptor signalling. Further analysis of HIP-55 revealed that this adaptor protein becomes increasingly associated with both Syk and integrin beta 3 upon platelet activation. Analysis of HIP-55 deficient platelets revealed reduced fibrinogen binding upon thrombin stimulation, suggesting HIP-55 to be an important regulator of platelet function.

Space, authenticity and utopia in the hip-hop teen dance film

The dance film flourished in the 2000s in the form of the hip-hop teen dance film. Such films as Save the Last Dance (Thomas Carter, 2001), Honey (Billy Woodruff, 2002) and Step Up (Anne Fletcher, 2006) drew on hip-hop’s dominance of the mainstream music industry and combined the teen film’s pre-existing social problem and musical narratives. Yet various tension were created by their interweaving of representations of post-industrial city youth with the utopian sensibilities of the classical Hollywood musical. Their narratives celebrated hip-hop performance, and depicted dance’s ability to bridge cultural boundaries and bring together couples and communities. These films used hip-hop to define space and identity yet often constructed divisions within their soundscapes, limiting hip-hop’s expressive potential. This article explores the cycle’s celebration of, yet struggle with, hip-hop through examining select films’ interactions between soundscape, narrative and form. It will engage with these films’ attempts to marry the representational, narrative and aesthetic meanings of hip-hop culture with the form and ideologies of the musical genre, particularly the tensions and continuities that arise from their engagement with the genre’s utopian qualities identified by Richard Dyer (1985). Yet whilst these films illustrate the tensions and challenges of combining hip-hop culture and the musical genre, they also demonstrate an effective integration of hip-hop soundscape and the dancing body in their depiction of dance, highlighting both form’s aesthetics of layering, rupture and flow (Rose, 1994: 22).

A corpus approach to discursive constructions of a hip-hop identity

This chapter is an analysis of a 100,000-word corpus consisting of message-board postings on hip-hop websites. A discourse analysis of this corpus reveals three strategies employed by the posters to identify themselves as members of the hip-hop community in the otherwise anonymous setting of the internet: (1) defined openings and closings, (2) repeated use of slang and taboo terms, and (3) performance of verbal art. Each strategy is characterized by the codification of non-standard grammar and pronunciations characteristic of speech, as well as by the use of non-standard orthography. The purpose of the discourse is shown to be a performance of identity, whereby language is used and recognized as the discursive construction of one’s hip-hop identity.

The fall descriptions and health characteristics of older adults with hip fracture : a mixed methods study

Background: In light of the multifactorial etiology of fall-related hip fracture, knowledge of fall circumstances may be especially valuable when placed in the context of the health of the person who falls. We aimed to investigate the circumstances surrounding fall-related hip fractures and to describe fall circumstances in relation to participants' health and functional characteristics. Methods: The fall circumstances of 125 individuals (age >= 50 years) with hip fracture were investigated using semi-structured interviews. Data concerning participants' health (comorbidities and medications) and function (self-reported performance of mobility, balance, personal activities of daily living and physical activity, previous falls and hand grip strength) were collected via medical records, questionnaires and dynamometry. Using a mixed methods design, both data sets were analysed separately and then merged in order to provide a comprehensive description of fall events and identify eventual patterns in the data. Results: Fall circumstances were described as i) Activity at the time of the fall: Positional change (n = 24, 19%); Standing (n = 16, 13%); Walking (n = 71, 57%); Balance challenging (n = 14, 11%) and ii) Nature of the fall: Environmental (n = 32, 26%); Physiological (n = 35, 28%); Activity-related indoor (n = 8, 6%) and outdoor (n = 8, 6%); Trips and slips on snow (n = 20, 16%) and in snow-free conditions (n = 12, 10%) and Unknown (n = 10, 8%). We observed the following patterns regarding fall circumstances and participants' health: those who fell i) during positional change had the poorest functional status; ii) due to environmental reasons (indoors) had moderate physical function, but high levels of comorbidity and fall risk increasing medications; iii) in snow-free environments (outdoors) appeared to have a poorer health and functional status than other outdoor groups. Conclusions: Our findings indicate that patterns exist in relation to the falls circumstances and health characteristics of people with hip fracture which build upon that previously reported. These patterns, when verified, can provide useful information as to the ways in which fall prevention strategies can be tailored to individuals of varying levels of health and function who are at risk for falls and hip fracture.

Hip hop sul : um espaço televisivo de formação e atuação musical

O presente trabalho investigou o programa televisivo Hip Hop Sul, veiculado pela TV Educativa do Rio Grande do Sul, e a sua relação com os músicos que dele participam, buscando entender as funções sócio-musicais e as experiências de formação e atuação musical que o programa desempenha. As técnicas utilizadas na coleta de dados foram a entrevista semi-estruturada, observações e acompanhamento da rotina de trabalho dos produtores do programa e registros em fotografias digitais e em audiovisuais da atuação dos grupos de rap e da produção do programa. A investigação foi desenvolvida na perspectiva dos estudos culturais (Wolf, 1995) e a análise dos dados foi feita com base no método de análise televisiva de Casetti e Chio (1998). O trabalho fundamenta-se na perspectiva da televisão como mediadora de conhecimentos musicais, (Fischer, 1997, 2000a, 2000b; Kraemer, 2000; Nanni, 2000 e Souza, 2000), a partir dos quais foram evidenciados os aspectos musicais formativos e atuantes presentes no Hip Hop Sul. Os aspectos abordados referem-se as experiências musicais dos grupos de rap como telespectadores e participantes do programa. Os resultados dessa pesquisa mostram que para esses grupos, ver a si mesmo ou sentir-se representados na televisão, significa existir, ter uma identidade e sair do anonimato. Estar na televisão é, portanto, uma experiência que modifica o ser e o fazer musical.
