Espaço e memória em o Vice-Cônsul de Marguerite Duras

No presente estudo pretendemos analisar o romance O Vice-cônsul, de Marguerite Duras, a partir dos temas memória e espaço, em que a relação entre esses temas perece ser desvendada à medida que percorremos a trajetória das principais personagens – mendiga, Anne-Marie Stretter e vice-cônsul. Nossa pesquisa faz também referência a diversas obras da autora – como O Amante, O deslumbramento de Lol V. Stein, Les lieux de Marguerite Duras, Boas falas: conversas sem compromisso – que servem de suporte a nossa análise, principalmente por que tais obras trazem à tona o universo literário durassiano que, em nosso entendimento, está vinculado às memórias da infância e da adolescência, fase que corresponde ao período passado na Indochina. Lugares e personagens, portanto, são constantemente reencontrados tendo suas histórias sempre utilizadas como matéria-prima para uma nova criação, negando inclusive qualquer fronteira entre as artes.

Habilidades sociais, competência acadêmica e problemas de comportamento em crianças com diferentes níveis de plumbemia

Este estudo teve como objetivo verificar a relação entre diferentes níveis de plumbemia e o repertório de habilidades sociais, problemas de comportamento e competência acadêmica de crianças e adolescentes. Participaram 155 crianças e adolescentes, com idade média de 13,10 anos, pertencentes a três grupos: alta plumbemia (superior a 10μg/dl), baixa plumbemia (inferior a 5μg/dl) e que viviam em ambiente similar, mas livre da contaminação por chumbo (grupo de comparação). Foram utilizados os instrumentos SSRS-BR e o IHSA-Del-Prette, respondidos pelos participantes e seus professores. Identificou-se comprometimento no repertório comportamental, acadêmico e social, associado ao nível de plumbemia. Esses resultados evidenciam os riscos associados à exposição ao chumbo. São discutidas explicações para alguns resultados contraditórios, levantando-se hipóteses e questões para novos estudos.

High precision astrometry mission for the detection and characterization of nearby habitable planetary systems with the Nearby Earth Astrometric Telescope (NEAT)

A complete census of planetary systems around a volume-limited sample of solar-type stars (FGK dwarfs) in the Solar neighborhood (d a parts per thousand currency signaEuro parts per thousand 15 pc) with uniform sensitivity down to Earth-mass planets within their Habitable Zones out to several AUs would be a major milestone in extrasolar planets astrophysics. This fundamental goal can be achieved with a mission concept such as NEAT-the Nearby Earth Astrometric Telescope. NEAT is designed to carry out space-borne extremely-high-precision astrometric measurements at the 0.05 mu as (1 sigma) accuracy level, sufficient to detect dynamical effects due to orbiting planets of mass even lower than Earth's around the nearest stars. Such a survey mission would provide the actual planetary masses and the full orbital geometry for all the components of the detected planetary systems down to the Earth-mass limit. The NEAT performance limits can be achieved by carrying out differential astrometry between the targets and a set of suitable reference stars in the field. The NEAT instrument design consists of an off-axis parabola single-mirror telescope (D = 1 m), a detector with a large field of view located 40 m away from the telescope and made of 8 small movable CCDs located around a fixed central CCD, and an interferometric calibration system monitoring dynamical Young's fringes originating from metrology fibers located at the primary mirror. The mission profile is driven by the fact that the two main modules of the payload, the telescope and the focal plane, must be located 40 m away leading to the choice of a formation flying option as the reference mission, and of a deployable boom option as an alternative choice. The proposed mission architecture relies on the use of two satellites, of about 700 kg each, operating at L2 for 5 years, flying in formation and offering a capability of more than 20,000 reconfigurations. The two satellites will be launched in a stacked configuration using a Soyuz ST launch vehicle. The NEAT primary science program will encompass an astrometric survey of our 200 closest F-, G- and K-type stellar neighbors, with an average of 50 visits each distributed over the nominal mission duration. The main survey operation will use approximately 70% of the mission lifetime. The remaining 30% of NEAT observing time might be allocated, for example, to improve the characterization of the architecture of selected planetary systems around nearby targets of specific interest (low-mass stars, young stars, etc.) discovered by Gaia, ground-based high-precision radial-velocity surveys, and other programs. With its exquisite, surgical astrometric precision, NEAT holds the promise to provide the first thorough census for Earth-mass planets around stars in the immediate vicinity of our Sun.

Acesso à educação infantil e trajetórias de desempenho escolar no ensino fundamental

No pressuposto de que a educação infantil (EI) contribui para trajetórias escolares mais favoráveis, o objetivo deste estudo foi verificar o impacto do tempo de exposição à educação infantil sobre o desempenho acadêmico e avaliar o progresso escolar das crianças, na trajetória do 3º ao 5º ano do ensino fundamental, em função da exposição à educação infantil. Participaram 294 alunos de escolas públicas, reunidos em três grupos: sem EI, com um ano de EI e com dois anos de EI. Avaliou-se o desempenho no 3º, 4º e 5º anos, por meio do julgamento do professor e provas coletivas. O Teste de Desempenho Escolar foi aplicado no 3º e 5º ano. Controlado o efeito do nível socioeconômico, a análise de variância com medidas repetidas mostrou que o acesso à EI foi consistentemente associado a melhor desempenho, porém um tempo maior de exposição à EI não teve efeito adicional. Dadas suas implicações para políticas públicas, este último resultado requer verificação e esclarecimento por meio de novas pesquisas.

Literatur im 21. Jahrhundert: Zeitgeistphänomene, Medienkonkurrenz, Funktion und ökonomische Aspekte der Ware Buch unter Bezugnahme auf aktuelle Entwicklungen in der Buchbranche

Welche Literatur liegt im Trend? Welche Aktionen und Instrumente bietet der Markt, um Bücher an den Leser zu vermitteln? Wie lässt sich das gegenwärtige Literaturverständnis beschreiben – auch in Abgrenzung und im Vergleich zu den etablierten Literaturtheorien? Diese allgemeinen Fragen wurden in der vorliegenden Arbeit spezialisiert und auf Schwerpunkte konzentriert. In den Vordergrund rückte – unter dem Aspekt des Zeitgeistphänomens – die junge deutsche Literatur, auf die bei diesem Projekt aus persönlichem Interesse heraus der Fokus gelegt wurde. Erforscht wurde, welche Bücher, Themen und Autoren zeitweise populär waren, wie es um Status und Selbstpräsentation letztgenannter bestellt war und ist. Als Beispiele zu nennen sind Benjamin von Stuckrad-Barre und Florian Illies, beide sich ihres (Markt-)Wertes wohl bewusste Vertreter der Pop- und Generationsliteratur, die in den letzten Jahren einen Boom erlebte. Beide Schriftsteller wurden mit ihren Werken einer detailgenauen Analyse unterzogen. Spricht man über Literatur, ist es unumgänglich, das – vorherrschende – nicht unproblematische Literaturverständnis zu durchleuchten. Galten Bücher einst als Status- und Bildungssymbol, ist von dieser Wertschätzung und von solch hohem Prestige heute nicht mehr allzu viel vorhanden. Das Erarbeiten eines Literaturbegriffs bot sich in der Auseinandersetzung mit in der Germanistik gängigen Theorien an (z. B. Empirische Theorie der Literatur nach S. J. Schmidt). Reduzierte man (als ein Ergebnis) Leistung und Wert von Literatur tatsächlich nur noch auf reine, unkomplizierte und schnelllebige Unterhaltung, führte dies zwangsweise zur Frage nach einer Medienkonkurrenz in erster Linie mit dem Fernsehen, dann mit dem Computer und seinen Möglichkeiten. Im dritten und letzten Abschnitt der Arbeit wurde anhand von ausgewählten Beispielen dargestellt, wie das gegenwärtige Literaturverständnis mit dem Markt konform geht, sprich welche Aktionen an der Schnittstelle Markt – Leser stattfinden, mit denen letztere auf Literatur aufmerksam gemacht und zum Lesen animiert werden sollen. In diesem Rahmen wurde u. a. das System der Literaturkritik knapp beschrieben und anhand von drei aktuellen Rezensionsbeispielen veranschaulicht.

A new yardstick for rating dental arch relationship in patients with complete bilateral cleft lip and palate

Objective: To develop yardsticks for assessment of dental arch relationship in young individuals with repaired complete bilateral cleft lip and palate appropriate to different stages of dental development. Participants: Eleven cleft team orthodontists from five countries worked on the projects for 4 days. A total of 776 sets of standardized plaster models from 411 patients with operated complete bilateral cleft lip and palate were available for the exercise. Statistics: The interexaminer reliability was calculated using weighted kappa statistics. Results: The interrater weighted kappa scores were between .74 and .92, which is in the "good" to "very good" categories. Conclusions: Three bilateral cleft lip and palate yardsticks for different developmental stages of the dentition were made: one for the deciduous dentition (6-year-olds' yardstick), one for early mixed dentition (9-year-olds' yardstick), and one for early permanent dentition (12-year-olds' yardstick).

Dental arch relationship in children with complete unilateral cleft lip and palate following one-stage and three-stage surgical protocols

The objective of this study is to compare dental arch relationship following one-stage and three-stage surgical protocols of unilateral cleft lip and palate. Dental casts of 61 children (mean age, 11.2 years; SD, 1.7), consecutively treated in one center with one-stage closure of the complete cleft at 9.2 months (SD, 2.0), were compared with a sample of 97 patients (mean age, 8.7 years; SD, 0.9), consecutively treated with a three-stage protocol including delayed hard palate closure in another center. The dental casts were assigned random numbers to blind their origin. Four raters graded dental arch relationship and palatal morphology using the EUROCRAN index. The strength of agreement of rating was assessed with kappa statistics. Independent t tests were run to compare the EUROCRAN scores between one-stage and three-stage samples, and Fisher's exact tests were performed to evaluate differences of distribution of the EUROCRAN grades. The intra- and inter-rater agreement was moderate to very good. Dental arch relationship in the one-stage sample was less favorable than in three-stage group (mean scores, 2.58 and 1.97 for one-stage and three-stage samples, respectively; p?

A longitudinal three-center study of dental arch relationship in patients with bilateral cleft lip and palate

OBJECTIVE: To compare and evaluate longitudinally the dental arch relationships from 4.5 to 13.5 years of age with the Bauru-BCLP Yardstick in a large sample of patients with bilateral cleft lip and palate (BCLP). DESIGN: Retrospective longitudinal intercenter outcome study. PATIENTS: Dental casts of 204 consecutive patients with complete BCLP were evaluated at 6, 9, and 12 years of age. All models were identified only by random identification numbers. SETTING: Three cleft palate centers with different treatment protocols. MAIN OUTCOME MEASURES: Dental arch relationships were categorized with the Bauru-BCLP yardstick. Increments for each interval (from 6 to 9 years, 6 to 12 years, and 9 to 12 years) were analyzed by logistic and linear regression models. RESULTS: There were no significant differences in outcome measures between the centers at age 12 or at age 9. At age 6, center B showed significantly better results (p=.027), but this difference diminished as the yardstick score for this group increased over time (linear regression analysis), the difference with the reference category (center C, boys) for the intervals 6 to 12 and 9 to 12 years being 10.4% (p=.041) and 12.9% (p=.009), respectively. CONCLUSIONS: Despite different treatment protocols, dental arch relationships in the three centers were comparable in final scores at age 9 and 12 years. Delaying hard palate closure and employing infant orthopedics did not appear to be advantageous in the long run. Premaxillary osteotomy employed in center B appeared to be associated with less favorable development of the dental arch relationship between 9 and 12 years.

Soft tissue profile changes after bilateral sagittal split osteotomy for mandibular setback: a systematic review

PURPOSE: To evaluate the ratio of soft tissue to hard tissue in bilateral sagittal split setback osteotomy with rigid internal fixation or wire fixation. MATERIALS AND METHODS: A literature search was performed using PubMed, Medline, CINAHL, Web of Science, the Cochrane Library, and Google Scholar Beta. From the original 766 articles identified, 8 articles were included. Two articles were prospective and 6 retrospective. The follow-up period ranged from 1 year to 12.7 years for rigid internal fixation. Two articles on wire fixation were found to be appropriate for inclusion. RESULTS: The differences between short- and long-term ratios of the lower lip to lower incisors for bilateral sagittal split setback osteotomy with rigid internal fixation or wire fixation were quite small. The ratio was 1:1 in the long term and by trend slightly lower in the short term. No distinction was seen between the short- and long-term ratios for mentolabial fold. The ratio was found to be 1:1 for the mentolabial fold to point B. In the short term, the ratio of the soft tissue pogonion to the pogonion showed a 1:1 ratio, with a trend to be lower in the long term. The upper lip showed mainly protrusion, but the amount was highly variable. CONCLUSIONS: This systematic review shows that evidence-based conclusions on soft tissue changes are difficult to draw. This is mostly because of inherent problems of retrospective studies, inferior study designs, and the lack of standardized outcome measurements. Well-designed prospective studies with sufficient samples and excluding additional surgery, ie, genioplasty or maxillary surgery, are needed.

Soft tissue profile changes after bilateral sagittal split osteotomy for mandibular advancement: a systematic review

PURPOSE: The purpose of the present systematic review was to evaluate the soft tissue/hard tissue ratio in bilateral sagittal split advancement osteotomy (BSSO) with rigid internal fixation (RIF) or wire fixation (WF). MATERIALS AND METHODS: The databases PubMed, Medline, CINAHL, Web of Science, Cochrane Library, and Google Scholar Beta were searched. From the original 711 articles identified, 12 were finally included. Only 3 studies were prospective and 9 were retrospective. The postoperative follow-up ranged from 3 months to 12.7 years for RIF and 6 months to 5 years for WF. RESULTS: The short- and long-term ratios for the lower lip to lower incisor for BSSO with RIF or WF were 50%. No difference between the short- and long-term ratios for the mentolabial-fold to point B and soft tissue pogonion to pogonion could be observed. It was a 1:1 ratio. One exception was seen for the long-term results of the soft tissue pogonion to pogonion in BSSO with RIF; they tended to be greater than a 1:1 ratio. The upper lip mainly showed retrusion but with high variability. CONCLUSIONS: Despite a large number of studies on the short- and long-term effects of mandibular advancement by BSSO, the results of the present systematic review have shown that evidence-based conclusions on soft tissue changes are still unknown. This is mostly because of the inherent problems of retrospective studies, inferior study designs, and the lack of standardized outcome measures. Well-designed prospective studies with sufficient sample sizes that have excluded patients undergoing additional surgery (ie, genioplasty or maxillary surgery) are needed.

A randomised comparison of novolimus-eluting and zotarolimus-eluting coronary stents: 9-month follow-up results of the EXCELLA II study

Novolimus, a macrocyclic lactone with anti-proliferative properties, has a similar efficacy to currently available agents; however it requires a lower dose, and less polymer, and is therefore conceivably safer.

Long-term effectiveness of canine-to-canine bonded flexible spiral wire lingual retainers

The flexible spiral wire (FSW) canine-to-canine lingual retainer bonded to all 6 anterior teeth is a frequently used type of mandibular fixed retainer. This study aimed to assess the long-term effectiveness of FSW canine-to-canine lingual retainers in maintaining the alignment of the mandibular anterior teeth after orthodontic treatment.

The recruitment of bone marrow-derived cells to skin wounds is independent of wound size

Wounded skin recruits progenitor cells, which repair the tissue defect. These cells are derived from stem cells in several niches in the skin. In addition, bone marrow-derived cells (BMDCs) are recruited and contribute to wound repair. We hypothesized that larger wounds recruit more cells from the bone marrow. Wild-type rats were lethally irradiated and transplanted with bone marrow cells from green fluorescent protein (GFP)-transgenic rats. Seven weeks later, 4, 10, and 20 mm wounds were created. The wound tissue was harvested after 14 days. The density of GFP-positive cells in the wounds and the adjacent tissues was determined, as well as in normal skin from the flank. Bone marrow-derived myofibroblasts, activated fibroblasts, and macrophages were also quantified. After correction for cell density, the recruitment of BMDCs (23±11%) was found to be independent of wound size. Similar fractions of GFP-positive cells were also detected in nonwounded adjacent tissue (29±11%), and in normal skin (26±19%). The data indicate that BMDCs are not preferentially recruited to skin wounds. Furthermore, wound size does not seem to affect the recruitment of BMDCs.
