Práticas inclusivas para deficientes visuais, baseadas na informação e conhecimento: reflexões e ações

We live in a society governed by information, knowledge and social inclusion. This leads us to reflect on the importance of access and use of information for people with visual disabilities to build knowledge, exercising citizenship and contribute to lifelong learning. We are faced with a society more open to diversity, questioning their mechanisms of segregation and envisions new ways of social inclusion of people with disabilities. Hence the importance of understanding the inclusive practices, especially for the visually impaired person. Thus, we sought to perform a literature search to understand the theoretical corresponding to the selective approach of the existing literature on the subject. It was considered as a concept of this type of research, which provides that a systematic search for information on existing sources, ie, in all the literature that has become public in relation to the subject studied in order to offer reflections and contributions on issues of access and use of information, emphasizing the role of social responsibility of mobilizing information professionals are considered mediators and actors of vital importance in this scenario.

A informação no rádio como estímulo a produção do conhecimento no ouvinte

The information is centralized on the oligopolistic control of large media conglomerates. Due to the oligopoly of the sources and agencies, can be seen by reviewing the programs for the transmission of information from different stations, there is a minimum difference maintained only for the sources of information of local character. The purpose of this article refers to present concepts and information guiding the radio programs and is in consensus with mediation in the communication process for the transmission of information may serve as a stimulus for the generation of knowledge.

INFERENCES FOR THE CHANGE-POINT OF THE EXPONENTIATED WEIBULL HAZARD FUNCTION

In many applications of lifetime data analysis, it is important to perform inferences about the change-point of the hazard function. The change-point could be a maximum for unimodal hazard functions or a minimum for bathtub forms of hazard functions and is usually of great interest in medical or industrial applications. For lifetime distributions where this change-point of the hazard function can be analytically calculated, its maximum likelihood estimator is easily obtained from the invariance properties of the maximum likelihood estimators. From the asymptotical normality of the maximum likelihood estimators, confidence intervals can also be obtained. Considering the exponentiated Weibull distribution for the lifetime data, we have different forms for the hazard function: constant, increasing, unimodal, decreasing or bathtub forms. This model gives great flexibility of fit, but we do not have analytic expressions for the change-point of the hazard function. In this way, we consider the use of Markov Chain Monte Carlo methods to get posterior summaries for the change-point of the hazard function considering the exponentiated Weibull distribution.

Coralistas amadores: auto-imagem, dificuldades e sintomas na voz cantada

Purpose: to evaluate vocal self-perception, difficulties and presence of negative symptoms after singing of amateur choir singers of different vocal classifications, age and experience. Method: one hundred and twenty five singers answered a questionnaire containing identification data, information about self-perception of the singing voice, difficulties with singing and negative symptoms after singing. Results: the comparison considering vocal classification evidenced greater difficulties with high notes for altos and basses, greater difficulty regarding the transition to high notes for basses and greater vocal fatigue for altos. Comparing the singers by age, both adults and young adults referred more breathiness than the elderly. The adults referred better vocal intensity than the young adults. The young adults referred better timbre than adults. Regarding the experience, the less experienced singers reported self-perception of hoarseness and presence of hoarseness after singing in greater number than the experienced singers. Conclusion: the difficulties with singing are connected to the vocal classification and do not depend on age or experience. Vocal symptoms are related to the vocal classification and to the experience with singing. Negative self-perception is also related the vocal classification and to the experience with singing, and positive self-perception was more reported by experienced singers.

The cascudos of the genus Hypostomus Lacépède (Ostariophysi: Loricariidae) from the rio Iguaçu basin

We reviewed several large collections of the genus Hypostomus from the rio Iguaçu basin summing up to 793 specimens mainly from the Laboratório de Ictiologia do Departamento de Ecologia e Biologia Evolutiva from Universidade Federal de São Carlos, from fish collection of Núcleo de Pesquisas em Limnologia, Ictiologia e Aquicultura da Universidade Estadual de Maringá, and from the Museu de História Natural do Capão da Imbuia. Hypostomus albopunctatus, H. commersoni, H. derbyi, and H. myersi are redescribed and Hypostomus nigropunctatus is described as a new species. A practical key for identification of Hypostomus species from the rio Iguaçu is also provided.

Neue Methoden zur Computersimulation von Polymersystemen auf verschiedenen Längenskalen und ihre Anwendungen

In dieser Dissertation stellen wir einen neuen Ansatz zurModellierungvon Polymersystemen vor. Es werden (von methodischer Seiteher) zweiautomatisierte Iterationschemata dazu eingeführt,Kraftfeldparametermesoskopischer Polymersysteme systematisch zu optimieren:DasSimplex-Verfahren und das Struktur-Differenzen-Verfahren. Sowerdendiejenigen Freiheitsgrade aus Polymersystemen eliminiert,die einehohe Auflösung erfordern, was die Modellierung größerersystemeermöglicht. Nach Tests an einfachen Flüssigkeiten werdenvergröberteModelle von drei prototypischen Polymeren (Polyacrylsäure,Polyvinylalkohol und Polyisopren) in unterschiedlichenUmgebungen(gutes Lösungsmittel und Schmelze) entwickelt und ihrVerhalten aufder Mesoskala ausgiebig geprüft. Die zugehörige Abbildung(vonphysikalischer Seite her) so zu gestalten, daß sie dieunverwechselbaren Charakteristiken jedes systems auf diemesoskopischeLängenskala überträgt, stellt eine entscheidende Anforderungan dieautomatisierten Verfahren dar.

Trading Values in Early Modern Antwerp

In his Descrittione di tutti i Paesi Bassi of 1567, the Italian merchant and humanist Ludovico Guicciardini described Antwerp as the warehouse of the world where all kinds of commodities were traded and displayed. Early modern Antwerp’s pre-eminent position depended upon links between material trade and exchange and the circulation of information, knowledge and beliefs. In this multidisciplinary volume of the NKJ, articles by leading scholars in the fields of art and material culture, literature and history explore ways in which value was propagated in the city from its so-called golden age, before the Revolt of the Netherlands, far into the seventeenth century.

Ophthalmic epidemiology in Europe: the "European Eye Epidemiology" (E3) consortium.

The European Eye Epidemiology (E3) consortium is a recently formed consortium of 29 groups from 12 European countries. It already comprises 21 population-based studies and 20 other studies (case-control, cases only, randomized trials), providing ophthalmological data on approximately 170,000 European participants. The aim of the consortium is to promote and sustain collaboration and sharing of data and knowledge in the field of ophthalmic epidemiology in Europe, with particular focus on the harmonization of methods for future research, estimation and projection of frequency and impact of visual outcomes in European populations (including temporal trends and European subregions), identification of risk factors and pathways for eye diseases (lifestyle, vascular and metabolic factors, genetics, epigenetics and biomarkers) and development and validation of prediction models for eye diseases. Coordinating these existing data will allow a detailed study of the risk factors and consequences of eye diseases and visual impairment, including study of international geographical variation which is not possible in individual studies. It is expected that collaborative work on these existing data will provide additional knowledge, despite the fact that the risk factors and the methods for collecting them differ somewhat among the participating studies. Most studies also include biobanks of various biological samples, which will enable identification of biomarkers to detect and predict occurrence and progression of eye diseases. This article outlines the rationale of the consortium, its design and presents a summary of the methodology.

VIS-NIR reflectance of water ice/regolith analogue mixtures and implications for the detectability of ice mixed within planetary regoliths

Permanently shadowed regions at the poles of the Moon and Mercury have been pointed out as candidates for hosting water ice at their surface. We have measured in the laboratory the visible and near infrared spectral range (VIS-NIR) bidirectional reflectance of intimate mixtures of water ice and the JSC-1AF lunar simulant for different ice concentrations, particle sizes, and measurement geometries. The nonlinearity between the measured reflectance and the amount of ice in the mixture can be reproduced to some extent by the mixing formulas of standard reflectance models, in particular, those of Hapke and Hiroi, which are tested here. Estimating ice concentrations from reflectance data without knowledge of the mixing coefficientsstrongly dependent on the size/shape of the grainscan result in large errors. According to our results, it is possible that considerable amounts of water ice might be intimately mixed in the regolith of the Moon and Mercury without producing noticeable photometric signatures.

Organic temperature proxies in the subpolat region around Iceland

Subpolar regions are key areas to study natural climate variability, due to their high sensitivity to rapid environmental changes, particularly through sea surface temperature (SST) variations. Here, we have tested three independent organic temperature proxies (UK'37, TEX86 and LDI) on their potential applicability for SST reconstruction in the subpolar region around Iceland. UK'37, TEX86 and TEXL86 temperature estimates from suspended particulate matter showed a substantial discrepancy with instrumental data, while long chain alkyl diols were below detection limit in most of the stations. In the northern Iceland Basin, sedimenting particles revealed a seasonality in lipid fluxes i.e. high fluxes of alkenones and GDGTs were measured during late spring-summer, and high fluxes of long chain alkyl diols during late summer. The flux-weighted average temperature estimates had a significant negative (ca. 2.3°C for UK'37) and positive (up to 5°C for TEX86) offset with satellite-derived SSTs and temperature estimates derived from the underlying surface sediment. UK'37 temperature estimates from surface sediments around Iceland correlate well with summer mean sea surface temperatures, while TEX86 derived temperatures correspond with both annual and winter mean 0-200 m temperatures, suggesting a subsurface temperature signal. Anomalous LDI-SST values in surface sediments, and low mass flux of 1,13- and 1,15-diols compared to 1,14-diols, suggest that Proboscia diatoms are the major sources of long chain alkyl diols in this area rather than eustigmatophyte algae, and therefore the LDI cannot be applied in this region.

Prioridades de manejo del riesgo de contaminación del recurso hídrico por efluentes

En el presente trabajo se propone y desarrolla una herramienta de "Gestión del riesgo de contaminación del recurso hídrico", inspirada en métodos comúnmente utilizados en las evaluaciones de impacto ambiental tales como la Matriz de importancia y la Evaluación de riesgo. Dicha herramienta se aplica en el oasis del río Tunuyán Inferior, cuya cuenca se localiza en el sector E de la Cordillera de Los Andes, provincia de Mendoza, Argentina. El método propuesto consiste en la determinación, en cada Unidad de Manejo (UM)3 de: 1. la vulnerabilidad del territorio; 2. la peligrosidad del efluente; 3. las clases de riesgo; 4. el índice prioridad de manejo del riesgo, variables que luego se traducen cartográficamente. Las bases de datos generadas pueden ser analizadas desde distintos enfoques y, a su vez, actualizadas a medida que se van profundizando los conocimientos acerca de los atributos que hacen a la peligrosidad del vertido (ej.: tipo de efluente, tiempo, caudal y lugar de descarga) y a la vulnerabilidad de la UM (ej.: tipo de acuífero, profundidad de nivel freático, permeabilidad del terreno, calidad del suelo, etc.). Esta herramienta de gestión genera un diagnóstico dinámico de la situación, ya que puede ser perfeccionado a través de la investigación de las variables que intervienen en el proceso de contaminación del agua por efluentes. Además, es una herramienta práctica porque jerarquiza las prioridades de gestión, de acuerdo con un orden de aplicación gradual de medidas de manejo del riesgo de contaminación. Teniendo en cuenta la tendencia mundial de reducción de glaciares por efecto del calentamiento global y su impacto negativo en los caudales de los ríos, es indispensable y urgente establecer prioridades de gestión para preservar la calidad del recurso hídrico.
