Acessibilidade dos conteúdos educacionais online na perspectiva da experiência do aluno cego

A educação a distância (EAD) proporciona acesso à educação de forma assíncrona, síncrona e livre de barreiras geográficas, permitindo que um grande número de pessoas, que de outra forma não poderiam estudar, deem continuidade à sua vida acadêmica. O acesso, no entanto, deve ser oferecido a todas as pessoas de forma igualitária tendo elas necessidades especiais ou nãoe não limitado ao nível instrumental, proporcionando um modelo de qualidade dinâmico que atenda às necessidades do aluno usuário. As plataformas de e-Learning têm o potencial para melhorar a qualidade do aprendizado e aumentar o acesso à educação desde que estejam atentas às necessidades dos diversos tipos de usuários(Carvalho e Daltrini, 2002)(Gilbert, Morton e Rowley, 2007). Perceber a possibilidade de contribuir investigando a experiência do usuário cego na sua interação com conteúdos educacionais online foi um dos motivos que motivou esta pesquisa. Este projeto pretende pesquisar o perfil de acessibilidade dos conteúdos dos sites educacionais a distância – e-Learning das universidades brasileiras na perspectiva da experiência do aluno cego ao interagir com os conteúdos educacionais online. A experiência do usuário – UX aluno cego ao interagir com os conteúdos educacionais nas plataformas de e-Learning é positiva? Há limitações que se apresentam para que ele atinja seus objetivos e tenha suas necessidades preenchidas? Usaremos para a obtenção dos dados questionários qualitativos e quantitativos online. Não há neste momento possibilidade de estabelecer um quantitativo para os questionários a serem distribuídos, seja porque não há estatísticas disponíveis no Ministério da Educação acerca da participação de usuários cegos nos cursos de graduação a distância, seja porque a estratégia proposta, de encaminhar questionários online impossibilita estimar o número de usuários que responderão à pesquisa. Esperamos efetuar uma avaliação UX – experiência do usuário global de forma a apresentar uma perspectiva, a mais completa que nos seja possível dentro desse universo, sobre a real experiência do aluno cego ao interagir com os conteúdos educacionais e-Learning nas universidades avaliadas. Os objetivos principais da pesquisa são: avaliar as condições de acessibilidade dos conteúdos educacionais online, nas instituições públicas brasileiras, na perspectiva da experiência do aluno cego ao interagir com eles; e, propor uma listagem de linhas de orientação para maximizar a sua experiência.
Rethinking the efficacy of acellular pertussis vaccines for primary immunization

Background The US has experienced a nationwide resurgence of pertussis since the mid-1970s, despite high vaccine coverage. Short-lived immunity induced by Diphtheria-Tetanus-acellular Pertussis (DTaP) vaccines in young children is widely believed to be responsible for this growing burden. However, the duration of protection conferred by DTaP vaccines remains incompletely quantified. Methods and Findings We employed a rigorously validated, age-structured model of pertussis transmission to explore a range of hypotheses regarding the degree of waning DTaP-derived immunity. For every hypothesis, we calculated the vaccine effectiveness and the relative increase in the odds of acquiring pertussis (or odds ratio) in children aged 5 to 9 years. We then assessed the simulated DTaP vaccine traits that best reproduced the empirical values of odds ratios from recent US epidemiological studies. We found a marked association between the degree of waning immunity, the vaccine effectiveness, and the odds ratio. Unexpectedly, the odds ratio was positively associated with the vaccine effectiveness, as a consequence of non-linear, age-assortative dynamics. Based on the empirical odds ratios, we estimated that vaccine effectiveness exceeded 75% and that more than 65% of children remained immune to pertussis 5 years after the last DTaP dose. Conclusions Our results show that temporal trends in the odds of acquiring pertussis are a seriously flawed measure of the durability of vaccine-induced protection. They further demonstrate that DTaP vaccines confer imperfect, but long-lived protection. We argue that control strategies should be based upon the best available estimates of vaccine properties and the age-structure of the transmission network.
Effects of Disruptive Innovation on the Employment Status and Income of Migrants and Non-migrants Engaging in Online Transportation, the City of Palembang

: This study was intended to explain how disruptive innovation, that is, online transportation affected the employment status and income of migrants and non-migrants in the City of Palembang. It employed a quantitative descriptive approach and acquired the data through surveys, with a sample size of 384 respondents working in a mobility service provider, GoJek. Then, the collected data were processed in a statistical analysis tool, SPSS 23, using the feature Cross Tabulation. The results showed that online transportation provided an opportunity for both unemployed and already employed populations. Also, it attracted migrants and non-migrants to either quit or keep their ﬁrst jobs in formal and informal sectors and work as online motorcycle taxi drivers. Relatively high income enticed many of them into earning a living solely from online transportation. However, some chose to undertake another job to receive additional income and, expectedly, improve their welfare and life standard.
Implementation of VARK Learning Styles in the MOOC User Interface Design

The development of technology has a lot of influence on the current educational process. One of the effects of technology is the development of Massive Open Online Course (MOOC) learning media which is still part of elearning. Massive and open MOOC has its own challenges in terms of scalability. Therefore, many researchers are now starting to develop interface designs that are in accordance with the characteristics of the students. This study aims to identify the learning styles of students in the MOOC course. The identification of student learning styles is done by filling out questionnaires that focus on the VARK method (Visual, Aural, Read, Kinetic). The results of the questionnaire analysis will be used as the basis by the researchers in designing the MOOC user interface that applies the VARK learning style.

High Precision Relative Positioning on a Mobile (poster)

Although there are many commercial products and services advertising their capability of indoor navigation using smartphone, still the service coverage is highly restricted to the specific area due to tremendous effort on pre-survey and maintenance on positioning resources such as radio map of Wi-Fi signals. Most of indoor positioning is dependent on the installed facilities such as Wi-Fi APs and BLE beacons in service area. Without pre-surveyed information such as fingerprint database, one can not localize himself at the first visiting site.
Comparación de dos métodos de muestreo visual de peces de arrecifes coralinos en la Bahía de Murdeira, isla de Sal, Cabo Verde

espanolEste estudio pretende comparar la eficacia dos metodos visuales de muestreo subacuatico en las comunidades de peces tropicales de la Bahia de Murdeira, en la costa suroeste de la isla de Sal, Cabo Verde. Se contrastaron dos tipos de metodos, el de transecto y el de punto fijo o circular. Los parametros valorados fueron la riqueza y la abundancia de especies asi como la diversidad (d’). Los resultados muestran diferencias significativas en la interaccion entre el metodo y la localidad, siendo solamente la Localidad 2 aquella que mostro diferencias significativas en las estimas generadas por cada metodo. El analisis de las especies muestreadas realizado para todo el experimento pone de manifiesto que el metodo circular es el mas completo, ya que es capaz de registrar mayor numero de especies y de individuos que el metodo del transecto. Por ultimo, el analisis de la diversidad revela que la localidad 2 es la mas diversa, coincidiendo con la unica localidad donde se encontraron diferencias en las estimas segun el metodo de muestreo utilizado. Con este estudio se pretende resaltar las ventajas de la utilizacion de metodologias no destructivas y la importancia de tener en cuenta las caracteristicas de la zona de estudio a la hora de elegir el metodo de muestreo. EnglishThis study aims to compare the efficiency of two underwater visual census methods on tropical fish communities of Murdeira bay, off the southwestern coast of Sal island, Cabo Verde. two methods were tested: strip belt transect and stationary point count. Parameters compared were: species richness, abundance and diversity (d’). The results show that there are significant differences due to the interaction between the method and location, being site 2 the one that showed significant differences in the estimates generated by each method. The analysis of species sampled performed for the entire experiment shows that the stationary point count method is the most complete, as it is able to record more species and individuals than the transect method. Finally, the diversity analysis reveals that site 2 is the most diverse, coinciding with the only location where differences in the estimates were found according to the sampling method used. This study highlight the advantages of using non-destructive methods and the importance of taking into account the characteristics of the study area for choosing the sampling method.
Expedition 336 : initiation of long-term coupled microbiological , geochemical , and hydrological experimentation within the seafloor at North Pond , western flank of the Mid-Atlantic Ridge

The Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) is designed to investigate fault mechanics and seismogenesis along a subduction megathrust, with objectives that include characterizing fault slip, strain accumulation, fault and wall rock composition, fault architecture, and state variables throughout an active plate boundary system. Integrated Ocean Drilling Program (IODP) Expedition 338 was planned to extend and case riser Hole C0002F from 856 to 3600 meters below the seafloor (m b.s.f.). Riser operations extended the hole to 2005.5 m b.s.f. , collecting logging-while-drilling (LWD) and measurement-while-drilling, mud gas, and cuttings data. Results reveal two lithologic units within the inner wedge of the accretionary prism that are separated by a prominent fault zone at ∼1640 m b.s.f. Due to damage to the riser during unfavorable winds and strong currents, riser operations were suspended, and Hole C0002F left for re-entry during future riser drilling operations. Contingency riserless operations included coring at the forearc basin site (C0002) and at two slope basin sites (C0021 and C0022), and LWD at one input site (C0012) and at three slope basin sites (C0018, C0021 and C0022). Cores and logs from these sites comprehensively characterize the alteration stage of the oceanic basement input to the subduction zone, the early stage of Kumano Basin evolution, gas hydrates in the forearc basin, and recent activity of the shallow megasplay fault zone system and associated submarine landslides.
Exploring social innovation (SI) within the research contexts of higher education, healthcare, and welfare services – a scoping review

Introduction: Nordic countries face societal challenges for which social innovation may represent solutions. The aim of this scoping review is to explore the concept of social innovation within the research contexts of higher education, ealthcare, and welfare services. Method: A scoping review methodology was used, including a literature search and the identification of eligible studies published between 2007 and 2019, in addition to data extraction and synthesis. Forty-three studies were included in this review. Results: Across the research contexts, social innovation is conceptualized as a set of novel, creative, human-centred, and value-driven processes aiming to bring about change. Qualitative research methods dominate social innovation research. In welfare services, social innovation concerns the relationship between policy and praxis, new forms of leadership and management, and the promotion of societal inclusion and cohesion. Social innovation in healthcare comprises the use of technology to digitalize service, enhance patients’ well-being, and improve service quality. In higher education, social innovation research focuses on educational reforms involving non-profit stakeholders. Discussion: Social innovation is a multifaceted concept related to change at the organizational or societal level, often with various stakeholders working together to create improvements. The lack of a common definition and framework of social innovation makes this concept difficult to measure or quantify, reflecting the dominance of qualitative research methods in the selected research contexts. Across these research contexts, social innovation can be defined and used for various research purposes, which are often political and value-based, with the latter connected to the common good and people’s well-being. Moreover, few social innovation studies have been performed in Nordic countries.
MAD saccade: statistically robust saccade threshold estimation via the median absolute deviation

Saccade detection is a critical step in the analysis of gaze data. A common method for saccade detection is to use a simple threshold for velocity or acceleration values, which can be estimated from the data using the mean and standard deviation. However, this method has the downside of being influenced by the very signal it is trying to detect, the outlying velocities or accelerations that occur during saccades. We propose instead to use the median absolute deviation (MAD), a robust estimator of dispersion that is not influenced by outliers. We modify an algorithm proposed by Nyström and colleagues, and quantify saccade detection performance in both simulated and human data. Our modified algorithm shows a significant and marked improvement in saccade detection - showing both more true positives and less false negatives – especially under higher noise levels. We conclude that robust estimators can be widely adopted in other common, automatic gaze classification algorithms due to their ease of implementation.
Concentration and Source of Trace Metals in Street Dust from an Industrial City in Semi-arid Area of China

The concentrations of trace metals in street dust of Baotou, an industrial city in semi-arid area of northwest China, were determined by X-ray fluorescence spectrometry. Sources of trace metals analyzed in the dust were identified based on their concentrations, enrichment factor and multivariate statistical analysis. The results indicate that the street dust of Baotou has elevated concentrations of Ba, Co, Cr, La, Pb and Sr, which are 1.2–4.7, 4.0–10.7, 1.7–5.8, 1.0–5.1, 1.2–8.7 and 1.5–2.6 times the background values of local soil, respectively. Cr, Pb, Ba, La and Sr in the dust were moderately enriched, while Co was significantly enriched. Cu and Zn had low concentrations to moderately enriched. Other determined trace metals were of low concentrations to minimally enriched. Hf, Zr, Ti, Y, Th, U and Ni mainly originated from natural sources. Ga, Sr and Co are primarily derived from industry and construction sources. La, Mn, V, Cr, Ba, Pb, Cu and Zn have mixed natural, industrial and traffic sources.

Methods to ensure reliable contact of super-large integrated circuit with test equipment

The design and technological problems arising from the use of contacting devices that connect an extra-large integrated circuit with test equipment during the testing process are considered. A review of the design and technological features of the contacting devices and an analysis of the causes of their main faults are given. Particular attention is paid to the analysis of the problems of the strength of the conclusions of the VLSI-chips implemented in BGA-cases. A method has been proposed that partially solves the problem of reducing the strength of the conclusions of a BGA-chip. It is shown that when high-speed interfaces are present in a chip, the maximum signal transfer rate is provided by the use of the Flip-Chip-technology for packaging ultra-large integrated circuits. A classification of contacting devices and of methods for their contacting with the chip is presented. An analysis of the advantages and disadvantages of contacting devices is given. Software and hardware complexes have been developed and a testing technique is proposed of contacting devices. Based on the test results, recommendations are proposed for choosing the most effective method of contacting ultra-large integrated circuits in FCBGA type housings with test equipment. The proposed methods of testing and hardware and software complexes allow you to test individually each of the hundreds of contacting devices with the chip being tested, that is, to obtain information on the failures of each contact.
Navigating Power and Claiming Justice: Tenant Experiences at Saskatchewan’s Housing Law Tribunal

This article discusses a qualitative interview project where twenty tenants shared their experiences about having hearings at the Office of Residential Tenancies [the ORT], Saskatchewan’s housing law tribunal. The interviews provide insights into housing problems faced by tenants, their experiences with self-representation at the ORT, and their reflections about the outcomes of their cases. We analyze how tenants prepared for their hearings, their experiences of the hearing process, and their perceptions of fairness throughout the process. We then discuss participants’ assessments of whether they received “justice” at the ORT. The interviews illuminate the ways that the same patterns of power and inequality that produce housing problems in the first place persist but are also occasionally interrupted and exposed in the housing tribunal process. They show also that tenants use the ORT to make important claims about justice and to resist landlord power in the face of larger patterns of inequality and exploitation.
