Multi-drug resistance profiles and the genetic features of Acinetobacter baumannii isolates from Bolivia

Introduction: Acinetobacter baumannii is opportunistic in debilitated hospitalised patients. Because information from some South American countries was previously lacking, this study examined the emergence of multi-resistant A. baumannii in three hospitals in Cochabamba, Bolivia, from 2008 to 2009. Methodology: Multiplex PCR was used to identify the main resistance genes in 15 multi-resistant A. baumannii isolates. RT-PCR was used to measure gene expression. The genetic environment of these genes was also analysed by PCR amplification and sequencing. Minimum inhibitory concentrations were determined for key antibiotics and some were determined in the presence of an efflux pump inhibitor, 1-(1-napthylmethyl) piperazine. Results: Fourteen strains were found to be multi-resistant. Each strain was found to have the bla(OXA-58) gene with the ISAba3-like element upstream, responsible for over-expression of the latter and subsequent carbapenem resistance. Similarly, ISAba1, upstream of the bla(ADC) gene caused over-expression of the latter and cephalosporin resistance; mutations in the gyrA(Ser83 to Leu) and parC (Ser-80 to Phe) genes were commensurate with fluoroquinolone resistance. In addition, the adeA, adeB efflux genes were over-expressed. All 15 isolates were positive for at least two aminoglycoside resistance genes. Conclusion: This is one of the first reports analyzing the multi-drug resistance profile of A. baumannii strains isolated in Bolivia and shows that the over-expression of thebla(OXA-58), bla(ADC) and efflux genes together with aminoglycoside modifying enzymes and mutations in DNA topoisomerases are responsible for the multi-resistance of the bacteria and the subsequent difficulty in treating infections caused by them.

La inconstitucionalidad por omisión legislativa en Bolivia

En la legislación boliviana no se encuentra normado el Recurso de Inconstitucionalidad por Omisión Legislativa, aunque es evidente la necesidad de su incorporación como un mecanismo de control constitucional de -omisiones de desarrollo normativo del Poder Legislativo-, con el objeto de restituir el orden constitucional y la eficacia plena de lo contenido en la Constitución Política del Estado. En este sentido, comenzamos revisando lo sostenido por la doctrina y la jurisprudencia constitucional de países donde no han instituido este recurso constitucional, como de aquellos que si lo incluyen en su legislación; para lo cual hacemos un examen de sus rasgos característicos. Con una base teórica y practica del señalado recurso, exploraremos la legislación boliviana en cuanto a las atribuciones del Tribunal Constitucional, respecto a los Recursos Directo e Indirecto de Inconstitucionalidad instituidos para la impugnación de –acciones inconstitucionales-; recursos que fueron interpretados por este órgano jurisdiccional como adecuado para el conocimiento también de omisiones legislativas, a pesar de no estar expresamente prescrito este control en el texto constitucional , ni en la Ley Nº 1836 (orgánica del Tribunal Constitucional). En este sentido, para identificar las consecuencias negativas de las omisiones del legislador, se analizan diferentes casos de omisiones de desarrollo normativo del Poder Legislativo. Para finalmente, proponer normativamente la incorporación del “Recurso de Inconstitucionalidad por Omisión Legislativa” en la legislación boliviana, como un mecanismo de control constitucional.

Los ángeles caídos: espejo eurocéntrico de la politología boliviana (1990-2008)

Este estudio da cuenta que la politología boliviana es parte de aquella estructura epistémica en América Latina que hace de nodo en la reproducción del poder colonial condicionando el espacio de lo posible de la política en Bolivia por la vía de la subalternización de saberes y formas de organización política, sobre todo, en un país que se caracteriza por su complejidad social, cultural y política. En este sentido, en lo específico el estudio estribó a estudiar a la ciencia política boliviana como una estructura institucional, es decir, una red compuesta por instituciones intelectuales/académicas (Instituto Latinoamericano de Investigaciones Sociales -ILDIS-Bolivia, Centro Boliviano de Estudios Multidisciplinarios-CEBEM, Fundación boliviana para la capacitación democrática- FUNDEMOS, Fundación Milenio, el Centro de Estudios de la Realidad Económica y Social-CERES, el Programa de Naciones Unidas para el Desarrollo PNUD-Bolivia, la Fundación Boliviana para la Democracia Multipartidaria-FBDM y el Instituto Prisma) todas ellas de algún modo se adscriben a la perspectiva teórica de la corriente institucionalista o a la del Pensamiento ILDIS. La politología boliviana legitimó científicamente la reproducción de la colonialidad del poder y las formas de explotación/dominación emergentes del orden democrático (neo) liberal. A posteriori, con la impronta de los indígenas en el poder al despuntar del siglo XXI, reprodujo la colonialidad del saber en su rol inferiorizador de otras formas de hacer política independientemente del canon de la democracia de occidente.

Journalists in film : heroes & villains

We both love and hate our journalists. They are perceived as sexy and glamorous on the one hand, despicable and sleazy on the other. Opinion polls regularly indicate that we experience a kind of cultural schizophrenia in our relationship to journalists and the news media: sometimes they are viewed as heroes, at other times villains. From Watergate to the fabrication scandals of the 2000s, journalists have risen and fallen in public esteem. In this book, leading journalism studies scholar Brian McNair explores how journalists have been represented through the prism of one of our key cultural forms, cinema. Drawing on the history of cinema since the 1930s, and with a focus on the period 1997-2008, McNair explores how journalists have been portrayed in film, and what these images tell us about the role of the journalist in liberal democratic societies. Separate chapters are devoted to the subject of female journalists in film, foreign correspondents, investigative reporters and other categories of news maker who have featured regularly in cinema. The book also discusses the representation of public relations professionals in film. Illustrated throughout and written in an accessible and lively style suitable for academic and lay readers alike, Journalists in Film will be essential reading for students and teachers of journalism, and for all those concerned about the role of the journalist in contemporary society, not least journalists themselves. An appendix contains mini-essays on every film about journalism released in the cinema between 1997 and 2008.

Methodological developments in phenomenography : investing using information to learn in the discipline classroom

This paper discusses methodological developments in phenomenography that make it apropos for the study of teaching and learning to use information in educational environments. Phenomenography is typically used to analyze interview data to determine different ways of experiencing a phenomenon. There is an established tradition of phenomenographic research in the study of information literacy (ex: Bruce, 1997; 2008; Lupton, 2008; Webber, Boon, & Johnston, 2005). Drawing from the large body of evidence complied in two decades of research, phenomenographers developed variation theory, which explains what a learner can feasibly learn from a classroom lesson based on how the phenomenon being studied is presented (Marton, Runesson, & Tsui, 2004). Variation theory’s ability to establish the critical conditions necessary for learning to occur has resulted in the use of phenomenographic methods to study classroom interactions by collecting and analyzing naturalistic data through observation, as well as interviews concerning teachers’ intentions and students’ different experiences of classroom lessons. Describing the methodological developments of phenomenography in relation to understanding the classroom experience, this paper discusses the potential benefits and challenges of utilizing such methods to research the experiences of teaching and learning to use information in discipline-focused classrooms. The application of phenomenographic methodology for this purpose is exemplified with an ongoing study that explores how students learned to use information in an undergraduate language and gender course (Maybee, Bruce, Lupton, & Rebmann, in press). This paper suggests that by providing a nuanced understanding of what is intended for students to learn about using information, and relating that to what transpires in the classroom and how students experience these lessons, phenomenography and variation theory offer a viable framework for further understanding and improving how students are taught, and learn to use information.

Reconciling dilemmas of social justice in literacy lessons : a case study of preservice primary teachers

Literacy is promoted as one factor in overcoming disadvantage. In this paper, we employ Fraser’s (1997 & 2008) framing of social justice in order to analyse the disparate agendas of literacy education for improved outcomes in national policy. We do this to better understand the dilemmas confronting preservice teachers as they prepare to become teachers in complex education contexts. We then examine what 20 preservice primary teachers say about social justice in interview responses to a scripted scenario. Our findings demonstrate that most preservice teachers are trying to demonstrate that they have a well-placed commitment to teaching for social justice, however, most of our respondents are yet to frame productive practices that might work in providing socially just education for the students they will teach. These outcomes raise possibilities for future iterations of preservice teacher courses at the case study site and beyond.

Foodborne Yersinia : Identification and Molecular Epidemiology of Isolates from Human Infections

Yersinia enterocolitica and Yersinia pseudotuberculosis are among the major enteropathogenic bacteria causing infections in humans in many industrialized countries. In Finland, Y. pseudotuberculosis has caused 10 outbreaks among humans during 1997-2008. Some of these outbreaks have been very extensive involving over 400 cases; mainly children attending schools and day-care. Y. enterocolitica, on the contrary, has caused mainly a large number of sporadic human infections in Finland. Y. pseudotuberculosis is widespread in nature, causing infections in a variety of domestic and wild animals. Foodborne transmission of human infections has long been suspected, however, attempts to trace the pathogen have been unsuccessful before this study that epidemiologically linked Y. pseudotuberculosis to a specific food item. Furthermore, due to modern food distribution systems, foodborne outbreaks usually involve many geographically separate infection clusters difficult to identify as part of the same outbreak. Among pathogenic Y. enterocolitica, the global predominance of one genetically homogeneous type (bioserotype 4/O:3) is a challenge to the development of genetic typing methods discriminatory enough for epidemiological purposes, for example, for tracing back to the sources of infections. Furthermore, the diagnostics of Y. enterocolitica infections is hampered because clinical laboratories easily misidentify some other members of the Yersinia species (Y. enterocolitica–like species) as Y. enterocolitica. This results in misleading information on the prevalence and clinical significance of various Yersinia isolates. The aim of this study was to develop and optimize molecular typing methods to be used in epidemiological investigations of Y. enterocolitica and Y. pseudotuberculosis, particularly in active surveillance and outbreak investigations of Y. pseudotuberculosis isolates. The aim was also to develop a simplified set of phenotypic tests that could be used in routine diagnostic laboratories for the correct identification of Y. enterocolitica and Y. enterocolitica –like species. A PFGE method designed here for typing of Y. pseudotuberculosis was efficient in linking the geographically dispersed and apparently unrelated Y. pseudotuberculosis infections as parts of the same outbreak. It proved to be useful in active laboratory-based surveillance of Y. pseudotuberculosis outbreaks. Throughout the study period, information about the diversity of genotypes among outbreak and non-outbreak related strains of human origin was obtained. Also, to our knowledge, this was the first study to epidemiologically link a Y. pseudotuberculosis outbreak of human illnesses to a specific food item, iceberg lettuce. A novel epidemiological typing method based on the use of a repeated genomic region (YeO:3RS) as a probe was developed for the detection and differentiation between strains of Y. enterocolitica subspecies palearctica. This method was able to increase the discrimination in a set of 106 previously PFGE typed Finnish Y. enterocolitica bioserotype 4/O:3 strains among which two main PFGE genotypes had prevailed. The developed simplified method was a more reliable tool than the commercially available biochemical test kits for differentiation between Y. enterocolitica and Y. enterocolitica –like species. In Finland, the methods developed for Y. enterocolitica and Y. pseudotuberculosis have been used to improve the identification protocols and in subsequent outbreak investigations.

Leuconostoc spoilage of refrigerated, packaged foods

Leuconostoc spp. are lactic acid bacteria (LAB) implicated in food spoilage, especially on refrigerated, modified atmosphere packaged (MAP) meats. The overall aim of this thesis was to learn more about Leuconostoc spp. as food spoilage organisms with a focus on commercial products where LAB spoilage is considered a problem and the main factor limiting shelf-life. Therefore, we aimed to identify Leuconostoc spp. involved in food spoilage, as well as to characterise the spoilage reactions they caused and their contamination sources during poultry meat processing. In addition, we examined the distribution of strains of Leuconostoc gasicomitatum in different food commodities. Finally, we analysed the genome content of L. gasicomitatum LMG 18811 with a special focus on metabolic pathways related to food spoilage. The findings show that Leuconostoc gelidum and L.gasicomitatum were responsible for the discoloration and off-odours developed in beef steaks. Together with Leuconostoc mesenteroides, these Leuconostoc spp., also cause spoilage of vegetable sausages. In contrast, we showed that Leuconostoc spp. are not important for the shelf-life or quality of non-marinated broiler products although, in marinated broiler fillet products, Leuconostoc spp., L.gasicomitatum in particular, are considered spoilage organisms. Furthermore, the findings of the contamination survey we carried out in a poultry processing plant indicated that spoilage Leuconostoc spp. are derived from the processing environment rather than from the broilers, and that air movement distributes psychrotrophic spoilage LAB, including leuconostocs, and has an important role in meat contamination during poultry processing. Pulsed-field gel electrophoresis (PFGE) based genotyping of L. gasicomitatum strains demonstrated that certain genotypes are common in various meat products. In contrast, genotypes associated with meat were not recovered in vegetable-based sources. This suggests that these two food categories either become contaminated with, or favour the growth of different genotypes. Furthermore, the results indicated that the meat processing environment contributes to L. gasicomitatum contamination as certain genotypes were repeatedly identified from products of the same processing plant. Finally, the sequenced and annotated genome of L.gasicomitatum LMG 18811 allowed us to identify the metabolic pathways and reactions resulting in food spoilage.

Isso aqui é uma escola técnica: um estudo discursivo de falas de professores do CTUR sobre seu trabalho no ensino médio e no ensino técnico

O presente trabalho se propõe a identificar sentidos de ensino médio, ensino técnico e trabalho do professor que se atualizam no embate entre ensino para o trabalho e ensino médio, no Colégio Técnico da Universidade Rural do Rio de Janeiro. Um breve histórico sobre o ensino técnico no Brasil e sobre a história do CTUR foi traçado, a fim de entender possíveis raízes do conflito entre o ensino para o trabalho e o ensino médio. Para ouvir os professores falarem sobre o seu trabalho, optamos pela entrevista como um dispositivo metodológico, a fim de dar voz ao docente do CTUR, de modo que fosse possível ter acesso a textos sobre o embate não disponíveis em outras circunstâncias. (ROCHA, DAHER, SANTANNA, 2004). O aporte teórico desta pesquisa se fundamenta nos pressupostos da Análise do Discurso, no que se refere à concepção de prática discursiva e subjetividade (MAINGUENEAU, 1997, 2008, 2011); e no que concerne ao trabalho, na perspectiva ergológica (SCHWARTZ, 1997, 2010), em particular, os conceitos de experiência, trabalho, normas antecedentes e renormalizações. Para a análise dos fragmentos construídos a partir das falas dos professores, usamos os estudos de Koch (2011) sobre as modalidades do discurso; a heterogeneidade enunciativa, segundo Authier-Revuz (1990), e a negação polêmica, conforme Ducrot (1987). As análises nos levaram a refletir sobre alguns embates presentes nas falas dos professores, como, por exemplo, as especificidades do trabalho, o ensino para a academia ou para o mercado e a valorização do ensino médio. As conclusões apontam para a possibilidade da abertura de um debate relacionado às questões históricas, políticas e filosóficas sobre o embate ensino médio/ensino técnico a fim de contribuir para o entendimento das funções dos sujeitos no CTUR
