O objetivo deste estudo foi verificar, por meio de questionário, a percepção dos ortodontistas quanto a época ideal para o tratamento ortodôntico da má oclusão de Classe II de Angle, avaliar a eficiência deste tipo de tratamento em uma ou duas fases e identificar os diversos métodos de tratamento utilizados. A amostra constituiu de 163 ortodontistas brasileiros que responderam ao questionário via e-mail. O questionário continha perguntas do tipo aberta, semi aberta e fechada, e, para sua validação, foi realizado um teste piloto entre 15 ortodontistas, participantes ou ex-alunos do Programa de Pós-graduação em Odontologia da Universidade Metodista de São Paulo, que não foram inclusos neste trabalho. Os dados foram tabulados com a utilização de frequência absoluta (n) e frequência relativa (%). Para verificar a correlação entre as variáveis ordinais foi utilizado o Coeficiente de Correlação de Spearman. Para verificar a associação entre variáveis qualitativas nominais foi utilizado o teste do qui-quadrado. Em todos os testes foi adotado nível de significância de 5% (p<0,05). Todos os procedimentos estatísticos foram executados no programa Statistica v.5.1 (StatSoft Inc., Tulsa, USA). Observou-se que os ortodontistas brasileiros preferem tratar os pacientes portadores da má oclusão de Classe II durante a fase da dentadura mista tardia, onde a procura por tratamentos nos consultórios e/ou clínicas tem maior ocorrência entre 10 a 13 anos e no sexo feminino. Dentre as modalidades de tratamento, verificou-se que 25 a 50% dos profissionais tratam seus pacientes em duas fases, seja na utilização do Aparelho Extra Bucal (49,1%), Bionator (33,1%) ou propulsores mandibulares, como APM (17,8%), e, Elásticos Classe II (8,6%).

Rapid population increase and booming economic growth have caused a significant escalation in car ownership in many cities, leading to additional or, multiple traffic problems on congested roadways. The increase of automobiles is generating a significant amount of congestion and pollution in many cities. It has become necessary to find a solution to the ever worsening traffic problems in our cities. Building more roadways is nearly impossible due to the limitations of right-of-way in cities. Studies have shown that guideway transit could provide effective transportation and could stimulate land development. The Medium-Capacity Guideway Transit (MCGT) is one of the alternatives to solve this problem. The objective of this research was to better understand the characteristics of MCGT systems, to investigate the existing MCGT systems around the world and determine the main factors behind the planning of successful systems, and to develop a MCGT planning guide. The factors utilized in this study were determined and were analyzed using Excel. A MCGT Planning Guide was developed using Microsoft Visual Basic. ^ A MCGT was defined as a transit system whose capacity can carry up to 20,000 passengers per hour per direction (pphpd). The results shown that Light Rail Transit (LRT) is favored when peak hour demand is less than 13,000 pphpd. Automated People Mover (APM) is favored when the peak hour demand is more than 18,000 pphpd. APM systems could save up to three times the waiting time cost compared to that of the LRT. If comfort and convenience are important, then using an APM does make sense. However, if cost is the critical factor, then LRT will make more sense because it is reasonable service at a reasonable price. If travel time and safety (accident/crush) costs were included in calculating life-cycle “total” costs, the capital cost advantage of LRT disappeared and APM could become very competitive. The results also included a range of cost-performance criteria for MCGT systems that help planners, engineers, and decision-makers to select the most feasible system for their respective areas. ^

Routine monitoring of environmental pollution demands simplicity and speed without sacrificing sensitivity or accuracy. The development and application of sensitive, fast and easy to implement analytical methodologies for detecting emerging and traditional water and airborne contaminants in South Florida is presented. A novel method was developed for quantification of the herbicide glyphosate based on lyophilization followed by derivatization and simultaneous detection by fluorescence and mass spectrometry. Samples were analyzed from water canals that will hydrate estuarine wetlands of Biscayne National Park, detecting inputs of glyphosate from both aquatic usage and agricultural runoff from farms. A second study describes a set of fast, automated LC-MS/MS protocols for the analysis of dioctyl sulfosuccinate (DOSS) and 2-butoxyethanol, two components of Corexit®. Around 1.8 million gallons of those dispersant formulations were used in the response efforts for the Gulf of Mexico oil spill in 2010. The methods presented here allow the trace-level detection of these compounds in seawater, crude oil and commercial dispersants formulations. In addition, two methodologies were developed for the analysis of well-known pollutants, namely Polycyclic Aromatic Hydrocarbons (PAHs) and airborne particulate matter (APM). PAHs are ubiquitous environmental contaminants and some are potent carcinogens. Traditional GC-MS analysis is labor-intensive and consumes large amounts of toxic solvents. My study provides an alternative automated SPE-LC-APPI-MS/MS analysis with minimal sample preparation and a lower solvent consumption. The system can inject, extract, clean, separate and detect 28 PAHs and 15 families of alkylated PAHs in 28 minutes. The methodology was tested with environmental samples from Miami. Airborne Particulate Matter is a mixture of particles of chemical and biological origin. Assessment of its elemental composition is critical for the protection of sensitive ecosystems and public health. The APM collected from Port Everglades between 2005 and 2010 was analyzed by ICP-MS after acid digestion of filters. The most abundant elements were Fe and Al, followed by Cu, V and Zn. Enrichment factors show that hazardous elements (Cd, Pb, As, Co, Ni and Cr) are introduced by anthropogenic activities. Data suggest that the major sources of APM were an electricity plant, road dust, industrial emissions and marine vessels.

The Tara Oceans Expedition (2009-2013) was a global survey of ocean ecosystems aboard the Sailing Vessel Tara. It carried out extensive measurements of evironmental conditions and collected plankton (viruses, bacteria, protists and metazoans) for later analysis using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set includes properties of seawater, particulate matter and dissolved matter that were measured from discrete water samples collected with Niskin bottles during the 2009-2013 Tara Oceans expedition. Properties include pigment concentrations from HPLC analysis (10 depths per vertical profile, 25 pigments per depth), the carbonate system (Surface and 400m; pH (total scale), CO2, pCO2, fCO2, HCO3, CO3, Total alkalinity, Total carbon, OmegaAragonite, OmegaCalcite, and dosage Flags), nutrients (10 depths per vertical profile; NO2, PO4, N02/NO3, SI, quality Flags), DOC, CDOM, and dissolved oxygen isotopes. The Service National d'Analyse des Paramètres Océaniques du CO2, at the Université Pierre et Marie Curie, determined CT and AT potentiometrically. More than 200 vertical profiles of these properties were made across the world ocean. DOC, CDOM and dissolved oxygen isotopes are available only for the Arctic Ocean and Arctic Seas (2013).

Esta investigación pretende analizar, desde un punto de vista documental, el tratamiento periodístico dado por los principales medios impresos españoles a las informaciones sobre el nuevo partido político Podemos en el momento de su eclosión. Podemos es un fenómeno social que en muy breve espacio de tiempo cambió los parámetros políticos de España. Por ello, queremos conocer cómo los principales medios de comunicación elaboraron sus informaciones en ese contexto de novedad que supuso su aparición. La documentación es el pilar de la información periodística de calidad, razón por la que nos servimos de ella para medir, dentro del marco de nuestra investigación, la calidad del periodismo que se practicó con dicha formación política.

The present paper analyses the parallelism existing between academic and professional discourse regarding three interrelated subjects: journalists´ training needs, their adaptation to multimedia profile changes and recognition of University graduates via professional regulation. This study relies on a bibliographical review and brings together the opinion of five professional groups by means of an interview using an openended questionnaire. The results show a coincidence in both discourses regarding the need for firmly grounded training of the journalists with study plans which integrate the new profiles. At the same time, it reflects the discrepancy of the journalistic groups with regard to professional regulation based on the University degree, whose vindication does not appear to be a priority in academic circles.

Se trata de un análisis pormenorizado de los artículos publicados por Francisco Franco en el periódico Arriba entre los años 1945 y 1960 bajo los seudónimos de Jakim Boor, Hispanicus y Macaulay. Se lleva a cabo su disección en dos grandes categorías: enemigos del Régimen y política, economía y sociedad. Para ello, se toma como ejemplo el propio artículo de Hispanicus titulado “Lo político, lo económico y lo social”. En la primera de las dos grandes categorías se agrupan todos aquellos elementos abstractos -instituciones o ideologías- que Franco consideraba perjudiciales para la España que él gobernaba o que históricamente habían sido hostiles a este país; en la segunda se recogen el comentario sobre política en términos actuales o generales, las situaciones económicas y sociales así como los numerosos fragmentos de Historia de España que el dictador gustaba de incluir en sus colaboraciones periodísticas.

Two-dimensional metal nanoparticle arrays are normally constructed at liquid–oil interfaces by modifying the surfaces of the constituent nanoparticles so that they self-assemble. Here we present a general and facile new approach for promoting such interfacial assembly without any surface modification. The method use salts that have hydrophobic ions of opposite charge to the nanoparticles, which sit in the oil layer and thus reduce the Coulombic repulsion between the particles in the organic phase, allowing the particles to sit in close proximity to each other at the interface. The advantage of this method is that because it does not require the surface of the particles to be modified it allows nonmetallic particles including TiO2 and SiO2 to be assembled into dense interfacial layers using the same procedure as is used for metallic particles. This opens up a route to a new family of nanostructured functional materials.

This paper describes research carried out as part of a wider doctoral study on ‘the biography of music teachers, their understanding of musicality and the implications for secondary music education’. Music teachers will come from a range of diverse backgrounds, though research data would suggest that most seem to have been educated as ‘classical’ music performers which will have an affect on what they perceive to be central competencies in the development of young musicians. In turn, this will determine, to some extent, what is taught and learned in the secondary music classroom. This study explores the impact of the biography of secondary music teachers as they seek to develop the musicianship of their pupils and present the activities in which the young people will be expected to participate. A mixed methods approach has been taken, including surveys, observation and interviews. Surveys amongst a sample of experienced and trainee teachers have produced a range of quantitative data on respondents’ experience of and values related to music education; whilst qualitative data in the form of lesson observation notes and transcription of semi-structured interviews have been the result of working with a small sub-set of participants. The outcomes of study have suggested a clear link between biography and classroom practice but that there are also other potential tensions which arise, such as in the subject knowledge development of practitioners as they move from musician to teacher. Implications for a variety of stakeholders in secondary music education include a consideration of the development of subject knowledge together with potential review of national and local education policy, the nature of undergraduate music study and the ‘shape’ of initial teacher training in England.

A ansiedade na performance musical (APM) é um distúrbio que afeta alguns músicos independentemente da sua idade, experiência, dedicação ou tipo de instrumento. A APM se faz presente em músicos de orquestras, coros e solistas e surge como um fenômeno fisiológico, psicológico, cognitivo e emocional. Este trabalho consiste em uma pesquisa acerca da ansiedade na performance musical em uma orquestra portuguesa. Através da aplicação do questionário STAI-Y comparou-se como 36 músicos da Orquestra Filarmonia das Beiras se sentiram antes do concerto (ansiedade-estado) e em uma situação geral (ansiedade-traço). Além disso, correlacionou-se os dados obtidos com dados sobre a população portuguesa. Concluiu-se que os músicos da OFB não apresentaram diferenças significativas entre os dois momentos e apresentaram baixos índices de ansiedade-estado e ansiedadetraço comparativamente à população portuguesa.
