Voice Performance Evaluation of Street Children From Aracaju, Brazil Using Perceptual-Auditory and Acoustic Analyses

Objective. To compare the voice performance of children involved in street labor with regular children using perceptual-auditory and acoustic analyses.Methods. A controlled cross-sectional study was carried out on 7- to 10-year-old children of both genders. Children from both groups lived with their families and attended school regularly; however, child labor was evident in one group and not the other. A total of 200 potentially eligible street children, assisted by the Child Labor Elimination Programme (PETI), and 400 regular children were interviewed. Those with any vocal discomfort (106, 53% and 90, 22.5%) had their voices assessed for resonance, pitch, loudness, speech rate, maximum phonation time, and other acoustic measurements.Results. A total of 106 street children (study group [SG]) and 90 regular children (control group [CG]) were evaluated. the SG group demonstrated higher oral and nasal resonance, reduced loudness, a lower pitch, and a slower speech rate than the CG. the maximum phonation time, fundamental frequency, and upper harmonics were higher in the SG than the CG. Jitter and shimmer were higher in the CG than the SG.Conclusion. Using perceptual-auditory and acoustic analyses, we determined that there were differences in voice performance between the two groups, with street children having better quality perceptual and acoustic vocal parameters than regular children. We believe that this is due to the procedures and activities performed by the Child Labor Elimination Program (PETI), which helps children to cope with their living conditions.

Sleep-disordered breathing and orthodontic variables in children-Pilot study

Introduction: Sleep Disordered Breathing (SDB) is a highly prevalent condition associated with orofacial and dentofacial characteristics.Objective: the aim of this study was to verify the association of dental malocclusion, molar relationship, crossbite, open bite, overjet, overbite, and crowding with SDB in children aged 7-9 years.Materials and methods: Participating schools were selected randomly from within the public elementary school system. in the first phase of the study, the parents of 1216 children aged between 7 and 9 years old completed the Sleep Disturbance Scale for Children (SDSC) questionnaire and the children had to participate in a dental examination. the evaluation of occlusion was divided into sagittal analysis, vertical analysis, and transverse analysis. in the second phase, 60 children were selected randomly to be undergone polysomnography (PSG) at a sleep clinic.Results: Among the children included, 242 (19.9%) children had normal occlusion. of the 60 children, 50 underwent PSG and 40(80%) had SDB. the crossbite and open bite showed association with SDB, p = 0.04 in both.Conclusion: Crossbite and open bite malocclusions were associated with SDB, and may be predictive of SDB in children. Studies with larger numbers of participants are needed to investigate the association of other malocclusions with SDB, and randomized clinical trials are also needed to see whether orthodontic and/or functional jaw orthopedic treatment is an option for treating children with malocclusion and SDB.

Accelerated partial irradiation for breast cancer: Systematic review and meta-analysis of 8653 women in eight randomized trials

Background and purpose: Accelerated partial breast irradiation (APBI) is the strategy that allows adjuvant treatment delivery in a shorter period of time in smaller volumes. This study was undertaken to assess the effectiveness and outcomes of APBI in breast cancer compared with whole-breast irradiation (WBI). Material and methods: Systematic review and meta-analysis of randomized controlled trials of WBI versus APBI. Two authors independently selected and assessed the studies regarding eligibility criteria. Results: Eight studies were selected. A total of 8653 patients were randomly assigned for WBI versus APBI. Six studies reported local recurrence outcomes. Two studies were matched in 5 years and only one study for different time of follow-up. Meta-analysis of two trials assessing 1407 participants showed significant difference in the WBI versus APBI group regarding the 5-year local recurrence rate (HR = 4.54, 95% CI: 1.78-11.61, p = 0.002). Significant difference in favor of WBI for different follow-up times was also found. No differences in nodal recurrence, systemic recurrence, overall survival and mortality rates were observed. Conclusions: APBI is associated with higher local recurrence compared to WBI without compromising other clinical outcomes. (C) 2014 Elsevier Ireland Ltd. All rights reserved.

Políticas públicas e direito: democratização do acesso ao Sistema Federal de Ensino Superior

A presente dissertação tem como objeto de pesquisa as políticas públicas de democratização do ensino criadas após a Constituição Federal de 1988. Com as teorias de direito e desenvolvimento e a educação superior como pano de fundo, pretende-se relacionar aspectos do direito e políticas públicas sob o enfoque institucional, buscando compreender a realidade dos programas ProUni, Reuni, Fies e Lei de Cotas. Questiona-se, com base em uma em uma metodologia jurídica das políticas públicas, como são construídos os programas para democratização do acesso ao ensino superior tendo em vista os planos macro, meso e microinstitucional como definido por Bucci e como funcionam as ações governamentais de inclusão nas instituições superiores de ensino público e privado. A pesquisa possibilitou constatar que faltam arranjos mesoinstitucionais que coordenem as políticas, tornando-as complementares e mais coerentes entre si, Não foram encontradas agregações institucionais exclusivas para as políticas de acesso ao ensino superior.

The Impact of the Internet in Six Latin American Countries

Access to the Internet has grown exponentially in Latin America over the past decade. The International Telecommunications Union (ITU) estimates that in 2009 there were 144.5 million Internet users in South America, 6.4 million in Central America, and 8.2 million in the Caribbean, or a total 159.2 million users in all of Latin America.1 At that time, ITU reported an estimated 31 million Internet users in Mexico, which would bring the overall number of users in Latin America to 190.2 million people. More recent estimates published by Internet World Stats place Internet access currently at an estimated 204.6 million out of a total population of 592.5 million in the region (this figure includes Mexico).2 According to those figures, 34.5 per cent of the Latin American population now enjoys Internet access. In recent years, universal access policies contributed to the vast increase in digital literacy and Internet use in Argentina, Brazil, Chile, Colombia, and Costa Rica. Whereas the latter was the first country in the region to adopt a policy of universal access, the most expansive and successful digital inclusion programs in the region have taken hold in Brazil and Chile. These two countries have allocated considerable resources to the promotion of digital literacy and Internet access among low income and poor populations; in both cases, civil society groups significantly assisted in the promotion of inclusion at the grassroots level. Digital literacy and Internet access have come to represent, particularly in the area of education, a welcome complementary resource for populations chronically underserved in nations with a long-standing record of inadequate public social services. Digital inclusion is vastly expanding throughout the region, thanks to stabilizing economies, increasingly affordable technology, and the rapid growth in the supply of cellular mobile telephony. A recent study by the global advertising agency Razorfish revealed significant shifts in the demographics of digital inclusion in the major economies of South America, where Web access is rapidly increasing amid the lower middle class and the working poor.3 Several researchers have suggested that Internet access will bring about greater civic participation and engagement, although skeptics remain unsure this could happen in Latin America. Yet, there have been some recent instances of political mobilization facilitated through the use of the Web and social media applications, starting in Chile when “smart mobs” nationwide demonstrated against former Chilean President Michelle Bachelet when she failed to enact education reforms in May 2006. The Internet has also been used by marginalized groups and by guerrillas groups to highlight their stories. In sum, Internet access in Latin is no longer a medium restricted to the elite. It is rather a public sphere upon which civil society has staked its claim. Some of the examples noted in this study point toward a developing trend whereby civil society, through online grassroots movements, is able to effectively pressure public officials, instill transparency and demand accountability in government. Access to the Internet has also made it possible for voices on the margins to participate in the conversation in a way that was never previously feasible. 1 International Telecommunications Union [ITU], “Information Technology Public & Report,” accessed May 15, 2011, http://www.itu.int/. 2 Internet World Stats, “Internet Usage Statistics for the Americas,” accessed March 24, 2011, http://www.internetworldstats.com/stats2.htm 3 J.

Designing for Dual Submission of ETDs

The main objective is to get participants thinking about how they can solve problems associated with a dual submission of ETDs. Many institutions choose to archive ETDs in their repositories, but also mandate, insist, or permit ETDs to be submitted to ProQuest via the UMI ETD Administrator. The Administrator offers a no-submission-fee route for ETD inclusion in ProQuest’s ubiquitous subscription databases. At FIU, after deciding on a mandatory ETD Policy in July 2011, we considered moving from a payment/snail mail submission to altogether scrapping submission to ProQuest; however, our librarians made a case for keeping at least an option for ProQuest submission. After consideration of all the options, implementing the UMI ETD Administrator seemed the most logical because it relieves payment, paperwork, and snail mail. Unfortunately, the UMI ETD Administrator creates as many problems as it solves e.g., the dual submission. According to the Berkman Center’s Good Practices for University Open-Access Policies, the university should offer to make additional deposits outside of the institutional repository. Thus, we sought to find a way for the students to only submit once to our DigitalCommons Institutional Repository. By June 2012, we manually triaged our first batch of ETDs from our DigitalCommons to the UMI ETD Administrator; however, since that first batch we have identified problems with metadata submission, entering student information, and the ETD Administrator default setup. For instance, with our second batch, we eliminated discrepancies with the department field; in our third batch, we eliminated concerns with FERPA and submitting student information; in our fourth batch, we look to cut down the time of each manual submission. Attendees, with institutions considering the ETD Administrator, should expect to anticipate and solve several issues associated with implementing the system in conjunction with an institutional repository. Attendees, who work with both the ETD Administrator and an Institutional Repository, should expect to gain new ideas for eliminating a dual submission for students, a quicker publication turn around, and/or decreased workflow time.

A secure and efficient data sharing framework with delegated capabilities in hybrid cloud

Hybrid cloud is a widely used cloud architecture in large companies that can outsource data to the publiccloud, while still supporting various clients like mobile devices. However, such public cloud data outsourcing raises serious security concerns, such as how to preserve data confidentiality and how to regulate access policies to the data stored in public cloud. To address this issue, we design a hybrid cloud architecture that supports data sharing securely and efficiently, even with resource-limited devices, where private cloud serves as a gateway between the public cloud and the data user. Under such architecture, we propose an improved construction of attribute-based encryption that has the capability of delegating encryption/decryption computation, which achieves flexible access control in the cloud and privacy-preserving in datautilization even with mobile devices. Extensive experiments show the scheme can further decrease the computational cost and space overhead at the user side, which is quite efficient for the user with limited mobile devices. In the process of delegating most of the encryption/decryption computation to private cloud, the user can not disclose any information to the private cloud. We also consider the communication securitythat once frequent attribute revocation happens, our scheme is able to resist some attacks between private cloud and data user by employing anonymous key agreement.

Equal access to the opportunities available? Equity and diversity laws and policies in Australia

Australia has been populated for more than 40,000 years with Indigenous Australians joined by European settlers only 230 years ago. The first settlers consisted of convicts from more than 28 countries and members of the British army who arrived in 1788 to establish a British penal colony. Mass migration in the nineteenth century with one and a half million immigrants from Europe, principally from the United Kingdom and Ireland (Haines and Shlomowitz, 1992), established the continent as an Anglo society in the Pacific. In the twentieth century immigrants came from many European countries and in the latter decades from many parts of Asia and the Middle East (Collins, 1991, pp.10-13). In the 21st century Australia has an ethnically and culturally diverse population. The original Indigenous population of Australia accounts for approximately 460,000 or 2.5 per cent of the total population (ABS, 2006a). Estimates are that around 4.5m. persons in the population (close to 20 per cent), were born outside Australia with the majority of these arriving from Europe, principally the United Kingdom, and New Zealand (ABS, 2006b). Like many other countries, Australia has a legacy of discrimination and inequality in employment. Propelled by racist ideologies and the male breadwinner ideology, Indigenous Australians, and non-European immigrants, and women were barred from certain jobs and paid less for their work than any white male counterpart. These conditions were legally sanctioned through the industrial relations system and other laws in the nineteenth and first half of the twentieth century. Since the 1960s a dramatic change has occurred in social policy and national legislation and Australia today has an extensive array of laws which forbid employment discrimination on race, ethnicity, gender and many other characteristics, and other approaches which promote proactive organizational plans and actions to achieve equity in employment. This chapter outlines these developments.

Access to care for the poor living with chronic disease in India : an analysis of selected national health policies

Cette recherche sur les barrières à l’accès pour les pauvres atteints de maladies chroniques en Inde a trois objectifs : 1) évaluer si les buts, les objectifs, les instruments et la population visée, tels qu'ils sont formulés dans les politiques nationales actuelles de santé en Inde, permettent de répondre aux principales barrières à l’accès pour les pauvres atteints de maladies chroniques; 2) évaluer les types de leviers et les instruments identifiés par les politiques nationales de santé en Inde pour éliminer ces barrières à l’accès; 3) et évaluer si ces politiques se sont améliorées avec le temps à l’égard de l’offre de soins à la population pour les maladies chroniques et plus spécifiquement chez les pauvres. En utilisant le Framework Approach de Ritchie et Spencer (1993), une analyse qualitative de contenu a été complétée avec des politiques nationales de santé indiennes. Pour commencer, un cadre conceptuel sur les barrières à l’accès aux soins pour les pauvres atteints de maladies chroniques en Inde a été créé à partir d’une revue de la littérature scientifique. Par la suite, les politiques ont été échantillonnées en Inde en 2009. Un cadre thématique et un index ont été générés afin de construire les outils d’analyse et codifier le contenu. Finalement, les analyses ont été effectuées en utilisant cet index, en plus de chartes, de maps, d'une grille de questions et d'études de cas. L’analyse a tété effectuée en comparant les barrières à l’accès qui avaient été originalement identifiées dans le cadre thématique avec celles identifiées par l’analyse de contenu de chaque politique. Cette recherche met en évidence que les politiques nationales de santé indiennes s’attaquent à un certain nombre de barrières à l’accès pour les pauvres, notamment en ce qui a trait à l’amélioration des services de santé dans le secteur public, l’amélioration des connaissances de la population et l’augmentation de certaines interventions sur les maladies chroniques. D’un autre côté, les barrières à l’accès reliées aux coûts du traitement des maladies chroniques, le fait que les soins de santé primaires ne soient pas abordables pour beaucoup d’individus et la capacité des gens de payer sont, parmi les barrières à l'accès identifiées dans le cadre thématique, celles qui ont reçu le moins d’attention. De plus, lorsque l’on observe le temps de formulation de chaque politique, il semble que les efforts pour augmenter les interventions et l’offre de soins pour les maladies chroniques physiques soient plus récents. De plus, les pauvres ne sont pas ciblés par les actions reliées aux maladies chroniques. Le risque de les marginaliser davantage est important avec la transition économique, démographique et épidémiologique qui transforme actuellement le pays et la demande des services de santé.

Right to asylum and border control : implications of european union policies on access to EU territory of people in need of international protection

Depuis plusieurs années, les États membres de l’Union européenne (UE) se soumettent à des politiques restrictives, en matière d’asile, qui les contraignent à respecter leur engagement de protéger les personnes qui fuient la persécution. Plusieurs politiques de dissuasion de l’UE sont controversées. Certaines ont d’abord été élaborées dans différents États, avant que l’UE ne mette en place une politique commune en matière d’asile. Certaines des ces politiques migratoires ont été copiées, et ont un effet négatif sur la transformation des procédures d’asile et du droit des réfugiés dans d’autres pays, tel le Canada. En raison des normes minimales imposées par la législation de l’UE, les États membres adoptent des politiques et instaurent des pratiques, qui sont mises en doute et sont critiquées par l’UNHCR et les ONG, quant au respect des obligations internationales à l'égard des droits de la personne. Parmi les politiques et les pratiques les plus critiquées certaines touchent le secteur du contrôle frontalier. En tentant de remédier à l’abolition des frontières internes, les États membres imposent aux demandeurs d’asile des barrières migratoires quasi impossibles à surmonter. Les forçant ainsi à s’entasser dans des centres de migration, au nord de l’Afrique, à rebrousser chemin ou encore à mourir en haute mer.
