Culture marked: racist epithets in translations of Mark Twain's Adventures of Huckleberry Finn

Aquest projecte analitza com s’ha plasmat el terme cultural nigger a dues traduccions al castellà de la novel•la Adventures of Huckleberry Finn de Mark Twain, amb l’objectiu d’estudiar de quina manera poden adaptar-se els elements culturals en una traducció. En primer lloc, s’ofereix la contextualització del terme original al text i a la cultura d’origen, seguida de la descripció del terme traduït en el context de la cultura d’arribada. A continuació, mitjançant l’anàlisi comparativa del mecanisme retòric de la repetició i d’elements com ara determinants, adjectius i complements, emprats tant a l’obra original com a les dues traduccions estudiades, aquest projecte pretén demostrar que la conservació dels esmentats recursos estilístics a la traducció pot facilitar la comprensió de les connotacions del marcador cultural nigger i de la seva funció temàtica al text d’arribada.

Epidermal growth factor and bovine growth hormone stimulate differentiation and myelination of brain cell aggregates in culture.

Bovine growth hormone (bGH) and epidermal growth factor (EGF) increased the activity of ornithine decarboxylase (ODC) in brain cell aggregates cultured in a serum-free chemically defined medium. ODC is considered as a marker of cell growth and differentiation. The effect of bGH and EGF on myelination was investigated by measuring two myelin markers, 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP) and myelin basic protein (MBP). EGF treatment at days 2 and 5 caused a dose-dependent increase of both myelin markers at culture day 12. This increase could still be observed at culture day 19, indicating a prolonged action of EGF. The continual presence of bGH in the culture medium produced a large accumulation of MBP at day 19. This effect was dose-dependent and required the presence of triiodothyronine (T3). In contrast, the effect of bGH on CNP activity did not require the presence of T3. This is the first report showing a direct effect of bGH on CNS myelination in vitro and of EGF on both MBP accumulation and ODC activity.

Clinical Learning Environment and Supervision. Development and Validation of the CLES Evaluation Scale

The purpose of the study is: (1) to describe how nursing students' experienced their clinical learning environment and the supervision given by staff nurses working in hospital settings; and (2) to develop and test an evaluation scale of Clinical Learning Environment and Supervision (CLES). The study has been carried out in different phases. The pilot study (n=163) explored the association between the characteristics of a ward and its evaluation as a learning environment by students. The second version of research instrument (which was developed by the results of this pilot study) were tested by an expert panel (n=9 nurse teachers) and test-retest group formed by student nurses (n=38). After this evaluative phase, the CLES was formed as the basic research instrument for this study and it was tested with the Finnish main sample (n=416). In this phase, a concurrent validity instrument (Dunn & Burnett 1995) was used to confirm the validation process of CLES. The international comparative study was made by comparing the Finnish main sample with a British sample (n=142). The international comparative study was necessary for two reasons. In the instrument developing process, there is a need to test the new instrument in some other nursing culture. Other reason for comparative international study is the reflecting the impact of open employment markets in the European Union (EU) on the need to evaluate and to integrate EU health care educational systems. The results showed that the individualised supervision system is the most used supervision model and the supervisory relationship with personal mentor is the most meaningful single element of supervision evaluated by nursing students. The ward atmosphere and the management style of ward manager are the most important environmental factors of the clinical ward. The study integrates two theoretical elements - learning environment and supervision - in developing a preliminary theoretical model. The comparative international study showed that, Finnish students were more satisfied and evaluated their clinical placements and supervision with higher scores than students in the United Kingdom (UK). The difference between groups was statistical highly significant (p= 0.000). In the UK, clinical placements were longer but students met their nurse teachers less frequently than students in Finland. Arrangements for supervision were similar. This research process has produced the evaluation scale (CLES), which can be used in research and quality assessments of clinical learning environment and supervision in Finland and in the UK. CLES consists of 27 items and it is sub-divided into five sub-dimensions. Cronbach's alpha coefficient varied from high 0.94 to marginal 0.73. CLES is a compact evaluation scale and user-friendliness makes it suitable for continuing evaluation.

International nursing : cultivating a culture of empowerment

International nursing has been a growing phenomenon throughout the globe. International nurses have been found to be an asset to healthcare organizations and an important part of the health care team. However, growing concern for the plight of international nurses facing obstacles such as professional stagnation and exploitation has spurred the development of strategies to mitigate and ameliorate the experiences of nurses working abroad. In this respect, the purpose of this study was to explore the management-influenced factors and the nurse team-influenced factors that promote the empowerment of the international nurse in the health care setting. The methodology used in this study was a systemic review. After a rigorous search for relevant empirical studies using OVID database, eight empirical research studies were selected using systematic review methodology to collect, analyze and synthesize data. The selected eight empirical studies were then subjected to a content analysis. The results suggested that the empowerment of an international nurse is inseparable from the empowerment of the health care organization. Based on the findings in this study, strategies to promote international nurses were found to mirror strategies evidenced to empower the nursing organization. Some of the management-influenced factors which were found to facilitate empowerment included a diversity rich work culture, transformational leadership at the management level, and a responsibility to foster the values of the organization. The team-influenced factors which were found to contribute to the empowerment of the international nurse included a united mutually-interdependent nurse team, shared accountability among the members of the nurse team, and the building of trust in work relationships. To conlude, this study indicates that efforts to empower international nurses without considering the work culture and the organization as a whole are futile because empowerment cannot take place in an environment that lacks antecedent conditions. Strategies to empower the international nurse should not focus on the deficits and special needs of the international nurse, but should focus on the similarities and commonalities of the nursing body. Empowerment of the international nurse mean open honest communication, supportive work environment, and a firm policy to quell disruptive elements that threaten the organization's values, mission, and philosophy of care.

Guerre de Troie, guerres des cultures et guerres du Golfe : les usages de "l'Illiade" dans la culture écrite américaine contemporaine

Depuis 1990 et la fin de la Guerre Froide, les Etats-Unis d'Amérique sont devenus la première puissance mondiale, animée par l'idéal de défendre les valeurs occidentale et de répandre la démocratie dans le monde. Or, entre des racines identitaires gréco-romaines empruntées à l'Europe, et les guerres menées au Moyen-Orient contre différents ennemis, la « mission » de l'Amérique suscite critiques et interrogations, et le conflit est autant culturel que militaire. L'Iliade d'Homère au contenu guerrier, érigée par la tradition littéraire en oeuvre fondatrice de l'Occident, offre aux penseurs américains de tous horizons un outil de réflexion propre à éclairer ce présent si inconfortable. A travers l'étude d'un corpus tripartite inédit, ce travail se propose de questionner le rôle d'une oeuvre symbolique de l'Antiquité grecque dans le monde d'aujourd'hui, et débouche sur une réflexion plus large touchant au sens contemporain des études classiques et à la transmission du savoir au sein de la culture populaire. Dans un premier temps, elle examine des ouvrages ou articles à vocation scientifique, mais publiés pour la plupart hors du cadre académique, qui théorisent et expriment les enjeux des guerres des cultures américaines (« culture wars ») divisant conservateurs et libéraux sur la mission véritable d'une éducation libérale. Ces ouvrages se servent également de l'Iliade comme d'un miroir où se reflète les conflits modernes, afin d'atténuer le trouble contemporain en juxtaposant passé et présent. Dans un deuxième temps sont abordés les médias journalistiques et informatiques, à l'aide des résultats obtenus lors de recherches poussées, effectuées dans les archives informatiques des journaux publiés dans les capitales et villes majeures des cinquante Etats américains. De fascinantes comparaisons entre la guerre de Troie et la guerre en Irak y sont notamment construites. Le discours sur l'actualité se développe par le recours à l'Antiquité, et en tire de nombreuses « leçons » destinées au gouvernement américain et à tous les meneurs de guerres. Et dans un troisième temps, deux romans de science-fiction, Ilium (2003) et sa suite Olympos (2005), de Dan Simmons, fournissent un fascinant complément littéraire au reste du corpus. Imprégnés par les culture wars, ils transposent l'Iliade dans un lointain futur et expriment sous une forme nouvelle toutes les interrogations brûlantes qui, aujourd'hui particulièrement, animent une Amérique troublée tant par ses guerres que par la remise en question de son identité occidentale. Par cette réunion de trois domaines dissemblables, ce travail pose aussi de nombreuses questions épistémologiques sur la circulation de l'information, la transformation des savoirs, le flou des frontières entre les genres, la révolution que représente Internet, et la fragmentation progressive de la bulle académique. Il propose également de nombreuses perspectives d'ouverture permettant de poursuivre cette recherche. Car la réception contemporaine de l'Iliade - et de l'Antiquité en général - est un domaine riche et dynamique, qui présente l'avantage - ou l'inconvénient, c'est selon - d'être toujours d'actualité. L'inconfort du présent ne devrait pas empêcher son étude, car les résultats sont extrêmement révélateurs de la véritable relation qu'entretiennent les hommes d'aujourd'hui - et non plus seulement les savants - avec leur passé.

Dual-wavelength digital holographic microscopy with sub-nanometer axial accuracy

We present dual-wavelength Digital Holographic Microscopy (DHM) measurements on a certified 8.9 nm high Chromium thin step sample and demonstrate sub-nanometer axial accuracy. We introduce a modified DHM Reference Calibrated Hologram (RCH) reconstruction algorithm taking into account amplitude contributions. By combining this with a temporal averaging procedure and a specific dual-wavelength DHM arrangement, it is shown that specimen topography can be measured with an accuracy, defined as the axial standard deviation, reduced to at least 0.9 nm. Indeed, it is reported that averaging each of the two wavefronts recorded with real-time dual-wavelength DHM can provide up to 30% spatial noise reduction for the given configuration, thanks to their non-correlated nature. ©2008 COPYRIGHT SPIE

The organizational culture of a Brazilian public hospital

The objective of this research was to analyze the organizational culture of a Brazilian public hospital. It is a descriptive study with quantitative approach of data, developed in a public hospital of São Paulo State, Brazil. The sample was composed by 52 nurses and 146 nursing technicians and auxiliaries. Data were collected from January to June 2011 using the Brazilian Instrument for Assessing Organizational Culture – IBACO. The analysis of the organizational values showed the existence of hierarchical rigidity and centralization of power within the institution, as well as individualism and competition, which hinders teamwork. The values concerning workers’ well-being, satisfaction and motivation were not highly valued. In regard to organizational practices, the promotion of interpersonal relationship, continuous education, and rewarding practices were not valued either. It becomes apparent that traditional models of work organization support work practices and determine the organizational culture of the hospital.


Secreted subtilisin gene family in Trichophyton rubrum.

Secreted proteases constitute potential virulence factors of dermatophytes. A total of seven genes encoding putative serine proteases of the subtilisin family (SUB) were isolated in Trichophyton rubrum. Based on sequence data and intron-exon structure, a phylogenetic analysis of subtilisins from T. rubrum and other fungi revealed a presumed ancestral lineage comprising T. rubrum SUB2 and Aspergillus SUBs. All other SUBs (SUB1, SUB3-7) are dermatophyte-specific and have apparently emerged more recently, through successive gene duplication events. We showed that two subtilisins, Sub3 and Sub4, were detected in culture supernatants of T. rubrum grown in a medium containing soy protein as a sole nitrogen source. Both recombinant enzymes produced in Pichia pastoris are highly active on keratin azure suggesting that these proteases play an important role in invasion of keratinised tissues by the fungus. The set of deduced amino acid sequences of T. rubrum SUB ORFs allowed the identification of orthologous Subs secreted by other dermatophyte species using proteolysis and mass spectrometry.

Ammonium alters creatine transport and synthesis in a 3D culture of developing brain cells, resulting in secondary cerebral creatine deficiency.

Hyperammonemic disorders in pediatric patients lead to poorly understood irreversible effects on the developing brain that may be life-threatening. We showed previously that some of these NH4+-induced irreversible effects might be due to impairment of axonal growth that can be protected under ammonium exposure by creatine co-treatment. The aim of the present work was thus to analyse how the genes of arginine:glycine amidinotransferase (AGAT) and guanidinoacetate methyltransferase (GAMT), allowing creatine synthesis, as well as of the creatine transporter SLC6A8, allowing creatine uptake into cells, are regulated in rat brain cells under NH4+ exposure. Reaggregated brain cell three-dimensional cultures exposed to NH4Cl were used as an experimental model of hyperammonemia in the developing central nervous system (CNS). We show here that NH4+ exposure differentially alters AGAT, GAMT and SLC6A8 regulation, in terms of both gene expression and protein activity, in a cell type-specific manner. In particular, we demonstrate that NH4+ exposure decreases both creatine and its synthesis intermediate, guanidinoacetate, in brain cells, probably through the inhibition of AGAT enzymatic activity. Our work also suggests that oligodendrocytes are major actors in the brain in terms of creatine synthesis, trafficking and uptake, which might be affected by hyperammonemia. Finally, we show that NH4+ exposure induces SLC6A8 in astrocytes. This suggests that hyperammonemia increases blood-brain barrier permeability for creatine. This is normally limited due to the absence of SLC6A8 from the astrocyte feet lining microcapillary endothelial cells, and thus creatine supplementation may protect the developing CNS of hyperammonemic patients.

SPECTRA OF MOTHERS OF PREMATURE CHILDREN ABOUT THE EDUCATIVE CIRCLE OF CULTURE

Abstract We sought to know the spectra of mothers of premature children regarding their experience with circle of culture of educational character and identifying the learning provided by the circle of culture about newborn care after hospital discharge. A descriptive study was performed in a hospital located in Fortaleza, Brazil. Three meetings of a circle of culture with 17 mothers of premature newborns were performed. The interpretation of the corpus was performed using thematic analysis. Emerged from the categories: Maternal experience in a circle of culture; Promoted social support among mothers through the circle of culture; and Learning provided by the circle of culture. It was concluded that teaching parents during the hospitalization of the child should be held in a way to involve parents in the care of the newborn, provide moments of health education, opportunities for support and dialogue between professionals and family.

Reflections on Young Women and the Youth Crisis in Sub-Saharan Africa

There has been an upsurge in academic studies on youth in Sub-Saharan Africa since the last decade of the 20th century, underlining the growing importance that generational cleavages seem to play in today’s societies. However, gender has been neglected in research and policies bearing on youth, unveiling a rather negative and limited approach to Sub-Saharan African youth: limit situations are those most focused on (as the role of youth in conflicts), young males being perceived as the most active in those contexts and who therefore shall be the focus of political (and academic) attention. Acknowledging the need to integrate gender in the approaches to youth, this paper tries to grasp, through a preliminary literature review, how the predicaments of the so-called “youth crisis” are lived and perceived by young girls, and identify the main themes and theoretical perspectives of the literature that has tried to explore this thematic.

Analysis of malaria associated genetic traits in Cabo Verde, a melting pot of European and sub Saharan settlers

Malaria has occurred in the Cabo Verde archipelago with epidemic characteristics since its colonization. Nowadays, it occurs in Santiago Island alone and though prophylaxis is not recommended by the World Health Organization, studies have highlight the prospect of malaria becoming a serious public health problem as a result of the presence of antimalarial drug resistance associated with mutations in the parasite populations and underscore the need for tighter surveillance. Despite the presumptive weak immune status of the population, severe symptoms of malaria are not observed and many people present a subclinical course of the disease. No data on the prevalence of sicklecell trait and red cell glucose-6-phosphate dehydrogenase deficiency (two classical genetic factors associated with resistance to severe malaria) were available for the Cabo Verde archipelago and, therefore, we studied the low morbidity from malaria in relation to the particular genetic characteristics of the human host population. We also included the analysis of the pyruvate kinase deficiency associated gene, reported as putatively associated with resistance to the disease. Allelic frequencies of the polymorphisms examined are closer to European than to African populations and no malaria selection signatures were found. No association was found between the analyzed human factors and infection but one result is of high interest: a linkage disequilibrium test revealed an association of distant loci in the PKLR gene and adjacent regions, only in non-infected individuals. This could mean a more conserved gene region selected in association to protection against the infection and/or the disease.
