Hodgkin lymphoma (HL) risk is elevated among persons infected with HIV (PHIV) and has been suggested to have increased in the era of combined antiretroviral therapy (cART). Among 14,606 PHIV followed more than 20 years in the Swiss HIV Cohort Study (SHCS), determinants of HL were investigated using 2 different approaches, namely, a cohort and nested case-control study, estimating hazard ratios (HRs) and matched odds ratios, respectively. Forty-seven incident HL cases occurred during 84,611 person-years of SHCS follow-up. HL risk was significantly higher among men having sex with men (HR vs intravenous drug users = 2.44, 95% confidence interval [CI], 1.13-5.24) but did not vary by calendar period (HR for 2002-2007 vs 1995 or earlier = 0.65, 95% CI, 0.29-1.44) or cART use (HR vs nonusers = 1.02, 95% CI, 0.53-1.94). HL risk tended to increase with declining CD4(+) cell counts, but these differences were not significant. A lower CD4(+)/CD8(+) ratio at SHCS enrollment or 1 to 2 years before HL diagnosis, however, was significantly associated with increased HL risk. In conclusion, HL risk does not appear to be increasing in recent years or among PHIV using cART in Switzerland, and there was no evidence that HL risk should be increased in the setting of improved immunity.

BACKGROUND:Accurate quantification of the prevalence of human immunodeficiency virus type 1 (HIV-1) drug resistance in patients who are receiving antiretroviral therapy (ART) is difficult, and results from previous studies vary. We attempted to assess the prevalence and dynamics of resistance in a highly representative patient cohort from Switzerland. METHODS:On the basis of genotypic resistance test results and clinical data, we grouped patients according to their risk of harboring resistant viruses. Estimates of resistance prevalence were calculated on the basis of either the proportion of individuals with a virologic failure or confirmed drug resistance (lower estimate) or the frequency-weighted average of risk group-specific probabilities for the presence of drug resistance mutations (upper estimate). RESULTS:Lower and upper estimates of drug resistance prevalence in 8064 ART-exposed patients were 50% and 57% in 1999 and 37% and 45% in 2007, respectively. This decrease was driven by 2 mechanisms: loss to follow-up or death of high-risk patients exposed to mono- or dual-nucleoside reverse-transcriptase inhibitor therapy (lower estimates range from 72% to 75%) and continued enrollment of low-risk patients who were taking combination ART containing boosted protease inhibitors or nonnucleoside reverse-transcriptase inhibitors as first-line therapy (lower estimates range from 7% to 12%). A subset of 4184 participants (52%) had >or= 1 study visit per year during 2002-2007. In this subset, lower and upper estimates increased from 45% to 49% and from 52% to 55%, respectively. Yearly increases in prevalence were becoming smaller in later years. CONCLUSIONS:Contrary to earlier predictions, in situations of free access to drugs, close monitoring, and rapid introduction of new potent therapies, the emergence of drug-resistant viruses can be minimized at the population level. Moreover, this study demonstrates the necessity of interpreting time trends in the context of evolving cohort populations.

Background. Racial disparities in healthcare span such areas as access, outcomes after procedures, and patient satisfaction. Previous work suggested that minorities experience less healthcare and worse survival rates. In adult orthotopic liver transplantation (OLT) mixed results have been reported, with some showing African-American recipients having poor survival compared to Caucasians, and others finding no such discrepancy. ^ Purpose. This study’s purpose was to analyze the most recent United Network for Organ Sharing (UNOS) data, both before and after the implementation of the Model for End-Stage Liver Disease (MELD)/Pediatric End-Stage Liver Disease (PELD) scoring system, to determine if minority racial groups still experience poor outcomes after OLT. ^ Methods. The UNOS dataset for 1992-2001 (Era I) and 2002-2007 (Era II) was used. Patient survival rates for each Era and for adult and pediatric recipients were analyzed with adjustment. A separate multivariate analysis was performed on African-American adult patients in Era II in order to identify unique predictors for poor patient survival. ^ Results. The overall study included 66,118 OLT recipients. The majority were Caucasian (78%), followed by Hispanics (13%) and African-Americans (9%). Hispanic and African-American adults were more likely to be female, have Hepatitis C, to be in the intensive care unit (ICU) or ventilated at time of OLT, to have a MELD score ≥23, to have a lower education level, and to have public insurance when compared to Caucasian adults (all p-values < 0.05). Hispanic and African-American pediatric recipients were more likely have public insurance and less likely to receive a living donor OLT than were Caucasian pediatric OLT recipients (p <0.05). There was no difference in the likelihood of having a PELD score ≥21 among racial groups (p >0.40). African-American adults in Era I and Era II had worse patient survival rates than both Caucasians and Hispanic (pair-wise p-values <0.05). This same disparity was seen for pediatric recipients in Era I, but not in Era II. Multivariate analysis of African-American recipients revealed no unique predictors of patient death. ^ Conclusions. African-American race is still a predictor of poor outcome after adult OLT, even after adjustment for multiple clinical, demographic, and liver disease severity variables. Although African-American and Hispanic subgroups share many characteristics previously thought to increase risk of post-OLT death, only African-American patients have poor survival rates when compared to Caucasians. ^

El trabajo analiza cómo se distribuyen las cargas y beneficios del modelo de acumulación post-convertibilidad, 2002-2007, entre las fracciones de clase. En este sentido exploramos la constitución de un sistema de transferencias de ingresos en el que convergen en un proceso dinámico la inflación, las políticas económicas y las estrategias de acumulación de los agentes económicos. Desde una perspectiva que amplía el modo de abordaje del debate sobre la distribución del ingreso, postulamos la conformación de un sistema de transferencias en base al análisis de dos núcleos vinculados: uno ligado a transferencias operadas a partir de la articulación de políticas económicas y transformaciones estructurales, y otro que es en sí mismo un mecanismo de transferencia de importante relevancia y alcance explicativo: la inflación. La evolución diferencial de los precios afecta la capacidad de apropiación, por los agentes económicos, del ingreso socialmente producido, expresando así cambios en las relaciones de fuerzas

A fines de 2001 Argentina llegó al clímax de la crisis del proceso neoliberal iniciado en los setenta. La crisis y su salida produjo la transición hacia un nueva modalidad de desarrollo periférica. Transición que no fue ruptura sino más bien superación dialéctica: lo nuevo surge de lo viejo que no desaparece sino que constituye el fundamento de aquello que está naciendo. El nuevo o neodesarrollismo nace así de las entrañas del neoliberalismo y de sus consecuencias económicas y sociales. Por un lado, resultará de la consolidación de un capitalismo periférico, dependiente y transnacionalizado. Por otra parte, supone el reconocimiento del peso de los nuevos movimientos populares que articularon la resistencia al ajuste durante los años noventa. Todo esto da cuenta de la impronta del proceso de crecimiento acelerado iniciado en 2002-2003 y de los cambios y continuidades manifiestos en la forma del Estado y sus políticas. Este texto pretende aportar elementos para comprender la novedad y la permanencia, lo estructural y lo accesorio, los límites y barreras del nuevo proceso. Por último, buscamos dar cuenta de las posibilidades de superar esos límites en la construcción de una alternativa popular.

The sensitivity of brightness temperature (T(B)) at 6.9, 10.7, and 18.7 GHz from Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E) observations is investigated over five winter seasons (2002-2007) on Great Bear Lake and Great Slave Lake, Northwest Territories, Canada. The T(B) measurements are compared to ice thicknesses obtained with a previously validated thermodynamic lake ice model. Lake ice thickness is found to explain much of the increase of T(B) at 10.7 and 18.7 GHz. T(B) acquired at 18.7 GHz (V-pol) and 10.7 GHz (H-pol) shows the strongest relation with simulated lake ice thickness over the period of study (R**2 > 0.90). A comparison of the seasonal evolution of T(B) for a cold winter (2003-2004) and a warm winter (2005-2006) reveals that the relationship between T(B) and ice growth is stronger in the cold winter (2003-2004). Overall, this letter shows the high sensitivity of T(B) to ice growth and, thus, the potential of AMSR-E mid-frequency channels to estimate ice thickness on large northern lakes.

Local trade between the Far East region of the USSR and the Northeast region of the People’s Republic of China started in 1957, arranged by the public trade organizations in the respective borderlands. Heilongjiang Province of China has been the main actor in trade with the Far East region of the USSR, and more recently, Russia. After 1957, Heilongjiang Province’s trade with the Russian Far East developed rapidly until 1993, except a period of interruption (1967-1982). Thereafter, the Heilongjiang Province’s trade with the Russian Far East underwent a stagnation period (1994-1998), a recovery period (1999-2001), a rapid development period (2002-2007) and a period of change of tendencies and radical decrease (2008-2009). Heilongjiang Province’s trade with the Russian Far East consists of three main forms: general trade, Chinese-style border trade (Bianjing Trade which includes Bianjing Small Trade and trade between private persons (Hushi Trade)) and Travel Trade. The rapid increase of Heilongjiang Province’s trade with the Russian Far East from 2002 to 2007 is mainly attributable to the increase in the export of ordinary consumer goods, especially textile clothing and footwear, and to Bianjing Small Trade.

During the first Kibaki administration (2002-2007), a movement by the former Mau Mau fighters demanded recognition for the role that they had played in the achievement of independence. They began to demand, also, monetary compensation for past injustices. Why had it taken over 40 years (from independence in 1963) for the former Mau Mau fighters to initiate this movement? What can be observed as the outcome of their movement? To answer these questions, three different historical currents need to be taken into account. These were, respectively, changing trends in the government of Kenya, progress in historical research into the actual circumstances of colonial control, and a realization, based on mounting experience, that launching a legal action against Britain could turn out to be a lucrative initiative. This paper concludes that, regardless of the actual purpose of the legal case, neither of their objectives was certain to be achieved. Two inescapable realities remain: the doubts cast on the reputation of the government by its decision to lift the Mau Mau‟s outlaw status – a decision that was widely seen as a latter-day example of the „Kikuyu favouritism‟ policy followed by the first Kibaki administration – and the popular interpretation of the involvement of Leigh Day, well known in Kenya ever since the unexploded bombs case for its success in obtaining substantial compensation payments, as a vehicle for squeezing large amounts of money from the British government for the benefit of the Kikuyu people.

トルコ社会において過去10年近くの間に,国家中心的な公共圏の認識が広まったのはなぜか。本稿はその主因を,2002~2007年に起きた「公共圏」論争が,イスラーム的スカーフの着用をめぐる論争に従属して展開したことに求め,新聞データベースを材料にした言説分析から,以下の答えを導く。第1に,2002年の論争開始にともない「公共圏」という表現が初めて広く一般の目に触れるようになったという点で,この論争による「公共圏」の宣伝効果は大きかった。しかしスカーフ着用問題が政治状況の変化により論争議題でなくなると,公共圏がどうあるべきかは,現状維持派の世俗派のみならず,挑戦者であるイスラーム派にとっても重要性がなくなったため,「公共圏」論争は失速した。第2に,現状維持派である世俗派エリートが用いた言説フレームは,国家が「公共圏」の中立性を守るためにスカーフ着用を禁止するというものだった。この支配的フレームに対し,イスラーム派は当初,ハーバマス的公共圏理論を援用してスカーフ着用を擁護する代替的対抗フレームを使っていた。しかし世俗派の強硬な抵抗に遭うと,国家的公共圏の抑圧性を強調する否定的対抗フレームをより頻繁に用いるようになった。これは世俗派批判としては妥当だったものの,イスラーム派が国家的公共圏定義を追認することにつながった。ちょうどその頃,「公共圏」論争は上述の理由で失速していた。そのため「公共圏」についてのトルコ社会のおおよその認識は,国家的定義が支配的なまま凍結されたのである。

The aim of this research paper is to analyse the key political posters made for the campaigns of Irish political party Fianna Fáil framed in the Celtic Tiger (1997-2008) and post-Celtic Tiger years (2009-2012). I will then focus on the four posters of the candidate in the elections that took place in 1997, 2002, 2007 and 2011 with the intention of observing first how the leader is represented, and later on pinpointing the similarities and possible differences between each. This is important in order to observe the main linguistic and visual strategies used to persuade the audience to vote that party and to highlight the power of the politician. Critical discourse analysis tools will be helpful to identify the main discursive strategies employed to persuade the Irish population to vote in a certain direction. Van Leeuwen’s (2008) social actor theory will facilitate the understanding of how participants are represented in the corpus under analysis. Finally, the main tools of Kress and van Leeuwen’s visual grammar (2006) will be applied for the analysis of the images. The study reveals that politicians are represented in a consistently positive way, with status and formal appearance so that people are persuaded to vote for the party they represent because they trust them as political leaders. The study, thus, points out that the poster is a powerful tool used in election campaigns to highlight the power of political parties.

Esta pesquisa analisou as relações das práticas pedagógicas e o conhecimento construído pelas professoras da educação infantil em cursos de formação continuada, a partir do trabalho desenvolvido no curso Encontros de Leitura , que ocorreu nos anos de 2007 e 2008 no Município de Sinop/MT, e que contou com a participação de professores de Educação Infantil da Rede Municipal de Educação atuando em turmas de Maternal II e III e turmas de Pré escola I e II. Este trabalho teve como suporte teórico, Duran, (2007, 2009); Nóvoa, (2007, 2009); Imbernón, (2009, 2010), Canário (1998, 2002, 2007) entre outros autores que discutem questões relacionadas aos processos de formação contínua de professores. A pesquisa foi tratada como um estudo de cunho qualitativo, utilizando-se de entrevistas semi-estruturadas e pesquisa bibliográfica. Contou com um grupo de cinco professoras da Educação Infantil que participaram do curso de formação continuada Encontros de Leitura com no mínimo setenta e cinco por cento de frequência durante os dois anos de vigência do mesmo. Para as discussões dos dados da pesquisa utilizou-se da análise de conteúdo de acordo com Bardin, (1997) e Franco, (2003). A pesquisa procurou investigar possíveis mudanças que podem ter ocorrido na prática pedagógica das professoras da rede Municipal de Sinop/MT. Considerando os dados analisados, é possível dizer que a frequência das professoras gerou um movimento de reorganização das práticas sociais de leitura, que envolvem a elaboração dos planejamentos e a realização das leituras diárias. No entanto, à prática de registrar as aprendizagens dos alunos, para futura analise, para uma sistematização do conhecimento, não foi apropriadas pelos professores. A pesquisa evidenciou o processo de desenvolvimento da formação continuada das professoras, com uma discussão sobre a forma como os professores incorporam, ou não, no cotidiano de sua prática pedagógica, resultados de discussões ocorridas no curso, contribuindo para um repensar processos e práticas de formação de professores.

Este estudo versa sobre a análise do processo de aprendizagem de alguns professores alfabetizadores da Rede Estadual de Educação de São Paulo e buscou compreender onde e como este grupo de profissionais aprende os conteúdos necessários para alfabetizar na perspectiva da construção de conhecimento. A hipótese que orienta esta análise é a de que um professor bem-formado tem mais condição de intervir na aprendizagem de seus alunos e, gradativamente, contribuir para a garantia do direito de todas as crianças se alfabetizarem. Parte também da hipótese de que, compreendendo o processo de aprendizagem destes educadores, as ações de formação podem ser mais eficazes. Por meio de pesquisa empírica, revisão bibliográfica e análise documental, esta dissertação organiza-se da seguinte forma: na Introdução é anunciada a trajetória profissional da proponente e sua relação com os programas de alfabetização e com as propostas de formação de educadores das Redes Públicas de Educação de São Paulo. O primeiro Capítulo tece a fundamentação teórica na qual os programas de formação de professores alfabetizadores de São Paulo são organizados. No segundo Capítulo é realizado um breve histórico sobre os programas de formação de professores alfabetizadores da Rede Estadual de Ensino, no período de 1984 a 2010, com uma análise sobre a coerência entre as concepções de ensino e aprendizagem, e as concepções que embasam os diferentes programas institucionais. No terceiro Capítulo são descritos os caminhos percorridos no processo de realização da pesquisa empírica. Nas Considerações Finais foram retomadas, em síntese, as discussões realizadas no desenvolvimento dos capítulos, recuperando a essência das análises a partir dos dados coletados, expressando os resultados da investigação. Foram aplicados questionários de perfil e realizadas entrevistas com 13 sujeitos envolvidos com o Programa Ler e Escrever da Rede Estadual de Ensino de São Paulo, envolvendo desde professores alfabetizadores até os organizadores do Programa. A fundamentação teórica deste estudo ocorreu, principalmente, a partir das contribuições de Piaget (1967); Ferreiro e Teberosky (1985); Ferreiro (1989; 1992; 2002; 2007); Becker (1993); Coll (1992); Lerner (2002) que se orientam pela concepção de construção de conhecimento e tratam da aprendizagem da leitura e escrita, da formação do professor e da didática da alfabetização e da Matemática; e Alarcão (2008), Lerner (2002) e Tardif (2002) que abordam a formação docente. A análise dos dados foi realizada a partir da fundamentação e dos procedimentos de Análise Temática do Conteúdo, conforme Bardin (2008) que resultou na elaboração de apreciações de condições que devem ser consideradas na formação de professores alfabetizadores. Os resultados obtidos apontam para algumas inferências sobre o processo de aprendizagem dos professores alfabetizadores que, se consideradas nas propostas, podem contribuir para a maior eficiência dos programas de formação, resultando em melhor apropriação pelos professores dos conteúdos envolvidos na alfabetização, na melhoria da qualidade da aprendizagem dos alfabetizandos e, consequentemente, na formação de leitores plenos e escritores eficientes.

With few exceptions (e.g. Fincham & Clark, 2002; Lounsbury, 2002, 2007; Montgomery & Oliver, 2007), we know little about how emerging professions, such as management consulting, professionalize and establish their services as a taken-for-granted element of social life. This is surprising given that professionals have long been recognized as “institutional agents” (DiMaggio & Powell, 1983; Scott, 2008) (see Chapter 17) and professionalization projects have been closely associated with institutionalization (DiMaggio, 1991). Therefore, in this chapter we take a closer look at a specific type of entrepreneurship in PSFs; drawing on the concept of “institutional entrepreneurship” (DiMaggio, 1988; Garud, Hardy, & Maguire, 2007; Hardy & Maguire, 2008) we describe some generic strategies by which proto-professions can enhance their “institutional capital” (Oliver, 1997), that is, their capacity to extract institutionally contingent resources such as legitimacy, reputation, or client relationships from their environment.
