The Population in Textbooks of American Geography: Colombia, (1970-1990)
Patricia Ceron
Universitas Humanística , 2012,
Abstract: In order to examine the social representation of the American population, we explored the discourse expressed in five textbooks of American geography that were published in Colombia between 1970 and 1990. We used tools proposed by Van Dijk (2008) and Wodak (2003) to study the ideological identity discourse of social groups, by tracking the positive portrayal of "us" and the negative representation of the "others". We found that the people of America are represented through the idea of race, a classification scheme that places the white category on the upper level as opposed to Indian and black, and through the ideology of development, which fosters a semantic polarization between Latin America and Anglo America
Emily and Charlotte Bront ’s Re-reading of the Byronic hero La réécriture du héros byronien par Emily et Charlotte Bront
Cristina Ceron
Revue LISA / LISA e-journal , 2010, DOI: 10.4000/lisa.3504
Abstract: The widespread popularity of Byron’s work during the Victorian age introduced several subversive possibilities for reading his characters as icons of transgression and insights into the literary tabooed. For Victorian novelists, one of the most intriguing aspects of his works was his obsessive explorations of literal or symbolic sibling incest, as the possibility that desire arises from an identification between male and female versions of the same psyche. Emily Bront ’s reading of Byron privileges this dark side of the literary myth, and her main focus is on the mysterious identity and Gothic aspects of the Byronic hero. Even though several critics have actually labelled the character of Heathcliff as ‘Byronic hero’, the debate has not delved into the textual or thematic evidence of the relation between Bront ’s protagonist and Byron hypertexts. My paper aims at investigating Bront ’s reading of Byron’s works, in particular her indebtedness to Manfred and to the relationship between Manfred and Astarte for the creation of the morbid passion experienced by Heathcliff and Catherine. The study will concentrate on Bront ’s appropriation and emphasis on the Gothic elements presented in nuce in Manfred, such as the spectral nature of Astarte, or the supernatural aspects of Manfred’s nature, whose will supersedes even Fate. My hypothesis is that Bront makes use of these aspects of Byron’s characters with the precise aim of setting the Gothic element as alternative narrative mode, as the subversive element inside a realistic novel. On the contrary, in spite of some juvenile experiments on the gothic, Charlotte’s reading of the Byronic hero is much more framed within the conventions of the realistic novel, and in the second section of my essay I maintain that what comes to the fore in Jane Eyre is the unsurpassed mastery the novelist shows in the combination of the realistic plot with the gothic elements and features of the protagonists. Far from enacting mere Romantic passion, the relationship between Jane and Rochester, just like Catherine’s liaison with Heathcliff, follows the textual dynamics of the Gothic romance, in that the woman falls prey to the more or less demonic instincts of her lover, suffers from the violence of his feelings and at the end is entangled by his thwarted passion, even though when we read the domestic happy ending we tend to forget the gothic matrix of the story… La popularité considérable dont jouissait l’ uvre de Byron pendant l’ère victorienne fut à l’origine de plusieurs lectures subversives considérant ses personnages comme des
Caenorhabditis elegans comes of age

Genome Biology , 2008, DOI: 10.1186/gb-2008-9-6-312
Abstract: In 1998, the publication of the genome sequence of Caenorhabditis elegans (a first for metazoans) and the discovery of RNA interference (RNAi) in this species provided a Big Bang for research using this model organism. What has happened since? Ten years later, scientists continue to squeeze the excellent experimental features of this animal to push the frontiers of knowledge forward in subjects as diverse as genomics, aging, behavior and development. Such breadth and variety was showcased at the recent European C. elegans conference http://www.upo.es/ewm2008 webcite. To take just one example, as evidenced at the meeting, genomic approaches often require validation that relies on genetics, and single-gene studies in return locate the gene of interest into larger functional networks. But the need to choose between the whole and the detail is long gone these days, because by now the 'wood' and the 'trees' are irreversibly connected.High-throughput work was presented by Mihail Sarov (Max Planck Institute, Dresden, Germany), who showcased the TransgeneOme project, based on an alternative recombination method for protein tagging. The TransgeneOme aims to provide an open resource of tagged fosmid transgenes for C. elegans at a genome-wide scale. The project is rolling and is initially focusing on proteins involved in transcriptional regulation as part of an international network, the modENCODE project http://www.modENCODE.org webcite, that aims to identify all functional DNA sequence elements in the C. elegans genome. Importantly, the TransgeneOme project is open for other protein sets from C. elegans to be included in their pipeline.Mark Edgley (University of British Columbia, Vancouver, Canada) reported on progress from the C. elegans Gene Knockout Consortium in Canada and the USA. As a result of the combined efforts of the Consortium, Shohei Mitani's group in Japan and the research community worldwide, approximately one-quarter (around 5,000) of all C. elegans genes has

Abstract: in chile, the prevalence of dental caries history in children aged 6 and 12 years is 70.3% and 62.5% respectively. therefore, the oral health program of the national board of student aid and scholarships (junaeb) carry out promotion, prevention and dental treatment to reduce this rate in more vulnerable populations, such as in frutillar school-children. the aim was to determine caries prevalence using dmft and dmft rates in 10-year-old children treated at the junaeb dental module in frutillar between 2007 and 2010. descriptive study. records were collected from 10 years old patients treated at the junaeb dental module between january 1, 2007 to december 31, 2010. for each year, we registered the number of patients, sex and dmft/dmft index. we evaluated the association of demographics with the history of caries using the chi-square test, t test and anova (p<0.05). there were 389 patients. 83.03% had a history of dental caries. the average dmft and dmft was 1.56 (sd±1.8) and 1.65 (sd±1.94) respectively. there was a significant reduction in dental caries history (p=0.04) and dmft index (p=0.001) in the last year. there was no association between dental caries history and sex or number of patients (p=0.57). the prevalence of of 10-year-old dental caries history decreased significantly between 2007 and 2010. ongoing cohort studies are warranted to assess the actual effect of the program in children between 6 and 12 years old.

Abstract: La distribución y el crecimiento de los líquenes están condicionados por diferentes factores ambientales, entre estos la variación en gradientes altitudinales. En la cordillera Oriental de los Andes de Colombia, no se han realizado estudios sobre zonación altitudinal de líquenes. En este trabajo se estudiaron las variaciones en la estructura de la comunidad de líquenes epifitos en un gradiente altitudinal (2000-2600 m) en el PNN Tatamá. Se encontró que con el aumento en altura hay una disminución en riqueza y diversidad, siendo esto una desviación del patrón encontrado generalmente en otros trabajos sobre líquenes y gradientes altitudinales. La comunidad a bajas alturas se compone principalmente de líquenes fruticosos (cobertura de 30% a 2070 m y 0% a 2560 m) y a mayores alturas de líquenes foliosos (cobertura de 15% a 2070 m y 43% a 2560 m). La altura, además de influenciar la estructura de la comunidad de los líquenes, puede afectar el desarrollo y la morfología de estos. En el género folioso Sticta se presentaron variaciones intraespecificas en la densidad de cifelas (órganos de intercambio gaseoso) asociadas a la altura, encontrándose un efecto significa

Victoria E. Ceron,Jorge G. Hirsch
Physics , 1999, DOI: 10.1016/S0370-2693(99)01317-9
Abstract: The double electron capture half-lives of 156Dy, 162Er and 168Yb are evaluated using the pseudo SU(3) model, which describes ground and excited bands as well as their B(E2) and B(M1) transition strengths in remarkable agreement with experiment. The best candidate for experimental detection is the decay 156Dy -> 156Gd, with tau{1/2} (0+{gs} --> 0+{gs}) = 2.74 E22 yrs and tau{1/2} (0+{gs} --> 0+{1}) = 8.31 E24 yrs.
A Transient Expression of Prospero Promotes Cell Cycle Exit of Drosophila Postembryonic Neurons through the Regulation of Dacapo
Jordi Colonques,Julian Ceron,Heinrich Reichert,Francisco J. Tejedor
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0019342
Abstract: Cell proliferation, specification and terminal differentiation must be precisely coordinated during brain development to ensure the correct production of different neuronal populations. Most Drosophila neuroblasts (NBs) divide asymmetrically to generate a new NB and an intermediate progenitor called ganglion mother cell (GMC) which divides only once to generate two postmitotic cells called ganglion cells (GCs) that subsequently differentiate into neurons. During the asymmetric division of NBs, the homeodomain transcription factor PROSPERO is segregated into the GMC where it plays a key role as cell fate determinant. Previous work on embryonic neurogenesis has shown that PROSPERO is not expressed in postmitotic neuronal progeny. Thus, PROSPERO is thought to function in the GMC by repressing genes required for cell-cycle progression and activating genes involved in terminal differentiation. Here we focus on postembryonic neurogenesis and show that the expression of PROSPERO is transiently upregulated in the newly born neuronal progeny generated by most of the larval NBs of the OL and CB. Moreover, we provide evidence that this expression of PROSPERO in GCs inhibits their cell cycle progression by activating the expression of the cyclin-dependent kinase inhibitor (CKI) DACAPO. These findings imply that PROSPERO, in addition to its known role as cell fate determinant in GMCs, provides a transient signal to ensure a precise timing for cell cycle exit of prospective neurons, and hence may link the mechanisms that regulate neurogenesis and those that control cell cycle progression in postembryonic brain development.
