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.

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.

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.

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.

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.

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 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.

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

渤海湾沿岸人口密集,工农、航运发达,渤海自身净化能力非常有限。因此,渤海湾 环境污染的压力越来越大,主要污染物包括重金属和持久性有机污染物的。四角蛤蜊广泛 分布于渤海湾海域,是一种重要的经济贝类,对污染物具有较强的富集能力。为了研究不 同站点渤海湾四角蛤蜊软体部重金属含量,选择大港油田、高沙岭码头、涧河村三个断面 进行研究,对不同站点四角蛤蜊软体部重金属含量进行了分析和讨论,最后对水生动物的 POPs 毒理调控通道进行了探索性研究,得到以下结果: 1. 通过比较渤海不同站点四角蛤蜊软体部重金属含量分布特征和方差分析,发现四 角蛤蜊软体部必需重金属元素含量较高,而非必需重金属元素含量较低,这是由于必需重 金属元素具有重要的生理功能作用。侧重比较A、B 两个断面各站位间四角蛤蜊软体部重 金属含量,发现虽然各站位间分布规律不明显,但各站位间差异显著。 2. 利用简单相关回归分析金属元素间及其与生物学性状间的关系,发现Mn 与Zn 之 间,Cu 与Zn 间均存在显著正相关,Se 与As、Cd 间存在显著正相关。另外,A 断面,BL 与Cd 含量显著负相关其回归方程为:Y(Cd)=-1395.97+88.34(BL);R=0.633;在B 断面,利用BW 和BH 分别与Cd 和As 显著负相关和显著正相关,其回归方程分别为:BW 和Cd 的回归方程为:Y(Cd)=-1968.80+220.72(BW);R=0.656。BH 和As 的回归方 程为:Y(As)=1496.86+227.82(BH);R=0.656。 3. 利用PLS(偏最小二乘分析)方法分析,发现五个生物学性状都与Co、As 呈正相 关,而与Cr、Pb、Se 呈负相关,而与必须重金属元素相关不明显。进一步分析表明表明 渤海湾海域中Co、As 含量低于四角蛤蜊正常生长发育的需要,而Cr、Pb、Se 的含量超过 四角蛤蜊正常生长发育所需的量。最后,通过PLS-DA 分析方法,发现C 站点样品能与A、 B 两个断面的站点区分开,而A、B 间未能区分开,反映了渤海湾三个断面的实际污染状 况。 4. 四角蛤蜊软体部重金属含量进行风险评价,首先,利用单因子污染指数法比较分析, 发现从1997 年-2008 年,渤海湾四角蛤蜊软体部Cd 的污染水平在不断降低,现在其含量 已低于《海洋生物质量标准》(第二类)标准。而Cr、As 有污染的趋势,需要引起重视。 然后,利用金属污染指数法进行比较研究,发现B 断面>A 断面>C 断面。最后,利用《人 体消费卫生标准》进行比较分析,发现Cd、Ni 存在轻度污染,因此需要加强其污染源的 控制。 5. 渤海湾污染物除了重金属外,还存在一些典型持久性有机污染物。为进一步揭示 二者间协同毒理机制,利用分子系统学方法,对芳香烃受体通道进行了探索性研究,发现 水生动物AhR通道基因在进化过程中发生了适应性进化,对进一步研究重金属和POPs对双 壳贝类的毒理机制具有参考价值。

Long term, high quality estimates of burned area are needed for improving both prognostic and diagnostic fire emissions models and for assessing feedbacks between fire and the climate system. We developed global, monthly burned area estimates aggregated to 0.5° spatial resolution for the time period July 1996 through mid-2009 using four satellite data sets. From 2001ĝ€ "2009, our primary data source was 500-m burned area maps produced using Moderate Resolution Imaging Spectroradiometer (MODIS) surface reflectance imagery; more than 90% of the global area burned during this time period was mapped in this fashion. During times when the 500-m MODIS data were not available, we used a combination of local regression and regional regression trees developed over periods when burned area and Terra MODIS active fire data were available to indirectly estimate burned area. Cross-calibration with fire observations from the Tropical Rainfall Measuring Mission (TRMM) Visible and Infrared Scanner (VIRS) and the Along-Track Scanning Radiometer (ATSR) allowed the data set to be extended prior to the MODIS era. With our data set we estimated that the global annual area burned for the years 1997ĝ€ "2008 varied between 330 and 431 Mha, with the maximum occurring in 1998. We compared our data set to the recent GFED2, L3JRC, GLOBCARBON, and MODIS MCD45A1 global burned area products and found substantial differences in many regions. Lastly, we assessed the interannual variability and long-term trends in global burned area over the past 13 years. This burned area time series serves as the basis for the third version of the Global Fire Emissions Database (GFED3) estimates of trace gas and aerosol emissions.
