Centros de recursos tecnológicos na Educação especial : um contributo para a sua avaliação

Na sociedade do conhecimento em que nos encontramos entendemos que todos os alunos devem ter acesso à informação e ao conhecimento, independentemente das suas capacidades e limitações. As novas tecnologias da informação e da comunicação constituem-se como uma mais-valia para os alunos com necessidades educativas especiais (NEE), sendo os apoios tecnológicos uma das soluções existentes para minorar as suas limitações físicas e intelectuais, aumentando deste modo, a qualidade de vida, a participação na sociedade e integração profissional dos mesmos. Para incluir digitalmente estes alunos, o Ministério da Educação criou os Centros de Recursos de Tecnologias da Informação e Comunicação (CRTIC, 2007), no sentido de cumprir com o Plano de Ação para a Integração das Pessoas com Deficiência (PAIPDI, 2006) e a reforma a Educação especial com a aplicação do decreto-lei n.º 3/08, de 7 de janeiro. Por conseguinte, decidimos investigar, após ter conhecimento da criação dos CRTIC para a Educação especial, realizando um estudo em cinco centros, a nível nacional, optando por uma investigação de natureza qualitativa, com entrevista, observação e pesquisa documental. O nosso principal objetivo foi verificar se estes centros disponibilizavam meios tecnológicos a todos os alunos com NEE, de acordo com os princípios da educação inclusiva ou se eram só para alguns. Após a análise dos dados recolhidos consideramos que existem algumas diferenças no cumprimento das normas orientadoras estipuladas pelo governo, no que diz respeito ao funcionamento e funções da equipa responsável, isto é, os responsáveis pelos centros incrementam a sua atividade essencialmente em duas vertentes: na avaliação dos alunos para adequação de tecnologias de apoio e acompanhamento/monitorização dos processos. Os docentes utilizadores dos centros disseram que os centros são úteis para a educação especial, no entanto, existe algum desconhecimento sobre os serviços prestados pelos mesmos.

How could construction supply chain benefit from RFID/GPS integration: a knowledge management perspective

Construction materials and equipment are essential building blocks of every construction project and may account for 50-60 per cent of the total cost of construction. The rate of their utilization, on the other hand, is the element that most directly relates to a project progress. A growing concern in the industry that inadequate efficiency hinders its success could thus be accommodated by turning construction into a logistic process. Although mostly limited, recent attempts and studies show that Radio Frequency IDentification (RFID) applications have significant potentials in construction. However, the aim of this research is to show that the technology itself should not only be used for automation and tracking to overcome the supply chain complexity but also as a tool to generate, record and exchange process-related knowledge among the supply chain stakeholders. This would enable all involved parties to identify and understand consequences of any forthcoming difficulties and react accordingly before they cause major disruptions in the construction process. In order to achieve this aim the study focuses on a number of methods. First of all it develops a generic understanding of how RFID technology has been used in logistic processes in industrial supply chain management. Secondly, it investigates recent applications of RFID as an information and communication technology support facility in construction logistics for the management of construction supply chain. Based on these the study develops an improved concept of a construction logistics architecture that explicitly relies on integrating RFID with the Global Positioning System (GPS). The developed conceptual model architecture shows that categorisation provided through RFID and traceability as a result of RFID/GPS integration could be used as a tool to identify, record and share potential problems and thus vastly improve knowledge management processes within the entire supply chain. The findings thus clearly show a need for future research in this area.

Strengthening artisanal mining research and policy through baseline census activities

Over the past 10-15 years, several governments have implemented an array of technology, support-related, sustainable livelihoods (SL) and poverty-reduction projects for artisanal and small-scale mining (ASM). In the majority of cases, however, these interventions have failed to facilitate improvements in the industry's productivity and raise the living standards of the sector's subsistence operators. This article argues that a poor understanding of the demographics of target populations has precipitated these outcomes. In order to strengthen policy and assistance in the sector, governments must determine, with greater precision, the number of people operating in ASM regions, their origins and ethnic backgrounds, ages, and educational levels. This can be achieved by carrying out basic and localized census work before promoting ambitious sector-specific projects aimed at improving working conditions in the industry.

Gestão do conhecimento e criação de valor: um estudo exploratório em empresas brasileiras

Nos últimos dez anos a gestão do conhecimento tem crescido em importância tanto no meio acadêmico como empresarial. Ainda que alguns permaneçam céticos, sua relevância para a competitividade das organizações tem se tornado cada vez mais um ponto de concordância nos dois ambientes, como uma resposta aos desafios sociais e econômicos impostos. Estes desafios impulsionam a gestão do conhecimento vista como uma disciplina interdisciplinar focada nos agentes e no seu ambiente, e no processo de criação, mapeamento e transferência do conhecimento, com o objetivo final de gerar vantagens competitivas sustentáveis. Apesar de muitos estudos específicos, ainda são poucos os trabalhos que buscam avaliar a adoção da gestão do conhecimento como abordagem ampla, quase como um novo paradigma gerencial adaptado à nova realidade econômica vigente, assim como são poucos os estudos que buscam avaliar o impacto na criação de valor de estratégias focadas no conhecimento. Este trabalho visa preencher essa lacuna, avaliando a adoção de práticas, conceitos e atitudes vinculadas à gestão do conhecimento em empresas de grande e pequeno porte criadoras de valor, através de estudos de caso. Para isso, o trabalho partiu de uma ampla revisão da literatura em torno do tema para definir um conjunto de práticas associadas ao conceito de gestão do conhecimento, dividido em seis dimensões: estratégia, estrutura, tecnologia da informação, cultura e pessoas, sistemas de suporte e processos. A partir deste levantamento, instrumentos distintos – questionário e roteiro de entrevista - foram elaborados para estudar as grandes e pequenas empresas. A pesquisa de campo só foi realizada após a validação do instrumento por especialistas na área, que avaliaram cada item com relação a sua total, parcial ou marginal associação ao conceito de gestão do conhecimento. Os resultados mostram que, independente do tamanho, as empresas criadoras de valor adotam muitas das práticas associadas a gestão do conhecimento em cinco das seis dimensões estudadas. Além destes indícios, o trabalho também contribui ao deixar um rol de mais de duzentos e trinta itens validados com relação ao conceito de gestão do conhecimento, que podem ser testados e aperfeiçoados.

Photodynamic Effects of Curcumin Against Cariogenic Pathogens

Background data: The presence of Streptococcus mutans and Lactobacillus acidophilus in dental structure is an indicator of a cariogenic biofilm. Photodynamic therapy is a technique that involves the activation of photosensitizers by light in the presence of oxygen, resulting in the production of reactive radicals capable of inducing cell death. Reduction of bacteria levels can provide additional means of preventing dental caries. Objective: The present study evaluated the susceptibility of planktonic cultures of S. mutans (ATCC 25175) and L. acidophilus (ATCC-IAL-523) from the Adolfo Lutz Institute (IAL) to photodynamic therapy after sensitization with curcumin and exposure to blue light at 450 nm. Methods: Bacterial suspensions of S. mutans and L. acidophilus isolated (as single species) and combined (multspecies) were prepared and then evaluated. Four different groups were analyzed: L-D- (control group), L-D+ (drug group), L+D- (light group), and L+D+ (photodynamic therapy group). Two different concentrations of curcumin were tested (0.75 and 1.5 g/L) associated with a 5.7 J/cm(2) light emission diode. Results: Significant decreases (p < 0.05) in the viability of S. mutans were only observed when the bacterial suspensions were exposed to both curcumin and light. Then, reductions in viability of up to 99.99% were observed when using 1.5 g/L of the photosensitizer. The susceptibility of L. acidophilus was considerably lower (21% and 37.6%) for both curcumin concentrations. Conclusions: Photodynamic therapy was found to be effective in reducing S. mutans and L. acidophilus on planktonic cultures. No significant reduction was found for L-D+, proving the absence of dark toxicity of the drug.

Deployment of human-machine dialogue systems.

The deployment of systems for human-to-machine communication by voice requires overcoming a variety of obstacles that affect the speech-processing technologies. Problems encountered in the field might include variation in speaking style, acoustic noise, ambiguity of language, or confusion on the part of the speaker. The diversity of these practical problems encountered in the "real world" leads to the perceived gap between laboratory and "real-world" performance. To answer the question "What applications can speech technology support today?" the concept of the "degree of difficulty" of an application is introduced. The degree of difficulty depends not only on the demands placed on the speech recognition and speech synthesis technologies but also on the expectations of the user of the system. Experience has shown that deployment of effective speech communication systems requires an iterative process. This paper discusses general deployment principles, which are illustrated by several examples of human-machine communication systems.

Development of The Readiness To Teach Online Scale

Despite the growing importance of online education, faculty acceptance has remained unchanged. Training programs developed for faculty to teach online have often focused on assessing their cognitive rather than affective and behavioral outcomes. The Readiness To Teach Online scale was developed as part of a multiphase mixed method research project to measure faculty perceptions and motivations toward teaching online. Items in the subcategory Teaching and Learning measured perceptions of technology and online teaching, and motivations regarding resources and other external factors. Items in the subcategories Social and Student Engagement, Faculty and Technology Support, Course Development and Instructional Design, and Evaluation and Assessment collected baseline data for current practices. The pilot study of this scale demonstrated strong internal consistency reliability estimates and support for validity, showing moderately to highly correlated significant relationships between faculty perceptions and motivation to teach online; both perception and motivation constructs were moderately to highly correlated with Social and Student Engagement.

Coordinated research support services at Queensland University of Technology, Australia

Queensland University of Technology (QUT) is a large multidisciplinary university located in Brisbane, Queensland, Australia. QUT is increasing its research focus and is developing its research support services. It has adopted a model of collaboration between the Library, High Performance Computing and Research Support (HPC) and more broadly with Information Technology Services (ITS). Research support services provided by the Library include the provision of information resources and discovery services, bibliographic management software, assistance with publishing (publishing strategies, identifying high impact journals, dealing with publishers and the peer review process), citation analysis and calculating authors’ H Index. Research data management services are being developed by the Library and HPC working in collaboration. The HPC group within ITS supports research computing infrastructure, research development and engagement activities, researcher consultation, high speed computation and data storage systems , 2D/ 3D (immersive) visualisation tools, parallelisation and optimization of research codes, statistics/ data modeling training and support (both qualitative and quantitative) and support for the university’s central Access Grid collaboration facility. Development and engagement activities include participation in research grants and papers, student supervision and internships and the sponsorship, incubation and adoption of new computing technologies for research. ITS also provides other services that support research including ICT training, research infrastructure (networking, data storage, federated access and authorization, virtualization) and corporate systems for research administration. Seminars and workshops are offered to increase awareness and uptake of new and existing services. A series of online surveys on eResearch practices and skills and a number of focus groups was conducted to better inform the development of research support services. Progress towards the provision of research support is described within the context organizational frameworks; resourcing; infrastructure; integration; collaboration; change management; engagement; awareness and skills; new services; and leadership. Challenges to be addressed include the need to redeploy existing operational resources toward new research support services, supporting a rapidly growing research profile across the university, the growing need for the use and support of IT in research programs, finding capacity to address the diverse research support needs across the disciplines, operationalising new research support services following their implementation in project mode, embedding new specialist staff roles, cross-skilling Liaison Librarians, and ensuring continued collaboration between stakeholders.

From social butterfly to engaged citizen: Urban informatics, social media, ubiquitous computing, and mobile technology to support citizen engagement

Web applications such as blogs, wikis, video and photo sharing sites, and social networking systems have been termed ‘Web 2.0’ to highlight an arguably more open, collaborative, personalisable, and therefore more participatory internet experience than what had previously been possible. Giving rise to a culture of participation, an increasing number of these social applications are now available on mobile phones where they take advantage of device-specific features such as sensors, location and context awareness. This international volume of book chapters will make a contribution towards exploring and better understanding the opportunities and challenges provided by tools, interfaces, methods and practices of social and mobile technology that enable participation and engagement. It brings together an international group of academics and practitioners from a diverse range of disciplines such as computing and engineering, social sciences, digital media and human-computer interaction to critically examine a range of applications of social and mobile technology, such as social networking, mobile interaction, wikis, twitter, blogging, virtual worlds, shared displays and urban sceens, and their impact to foster community activism, civic engagement and cultural citizenship.

Decision support to green technology implementation on Australian university campuses

As the societal awareness on sustainability is gaining momentum worldwide, the higher education sector is expected to take the lead in education, research and the promotion of sustainable development. Universities have the diversity of skills and knowledge to explore new concepts and issues, the academic freedom to offer unbiased observations, and the capacity to engage in experimentation for solutions. There is a global trend that universities have realized and responded to sustainability challenge. By adopting green technologies, buildings on university campuses have the potential to offer highly productive and green environments for a quality learning experience for students, while minimising environmental impacts. Despite the potential benefits and metaphorical link to sustainability, few universities have moved towards implementing Green Roof and Living Wall on campuses widely, which have had more successful applications in commercial and residential buildings. Few past research efforts have examined the fundamental barriers to the implementation of sustainable projects on campuses from organizational level. To address this deficiency, an on-going research project is undertaken by Queensland University of Technology in Australia. The research is aimed at developing a comprehensive framework to facilitate better decision making for the promotion of Green Roof and Living Wall application on campuses. It will explore and highlight organizational factors as well as investigate and emphasize project delivery issues. Also, the critical technical indicators for Green Roof and Living Wall implementation will be identified. The expected outcome of this research has the potential to enhance Green Roof and Living Wall delivery in Australian universities, as a vital step towards realizing sustainability in higher education sectors.

Nursing Sans Frontieres: A Three Year Case Study of Multi-State Registration of Support Nursing Practice Using Information Technology

Objective: To highlight the registration issues for nurses who wish to practice nationally, particularly those practicing within the telehealth sector. Design: As part of a national clinical research study, applications were made to every state and territory for mutual recognition of nursing registration and fee waiver for telenursing cross boarder practice for a period of three years. These processes are described using a case study approach. Outcome: The aim of this case study was to achieve registration in every state and territory of Australia without paying multiple fees by using mutual recognition provisions and the cross-border fee waiver policy of the nurse regulatory authorities in order to practice telenursing. Results: Mutual recognition and fee waiver for cross-border practice was granted unconditionally in two states: Victoria (Vic) and Tasmania (Tas), and one territory: the Northern Territory (NT). The remainder of the Australian states and territories would only grant temporary registration for the period of the project or not at all, due to policy restrictions or nurse regulatory authority (NRA) Board decisions. As a consequence of gaining fee waiver the annual cost of registration was a maximum of $145 per annum as opposed to the potential $959 for initial registration and $625 for annual renewal. Conclusions: Having eight individual nurses Acts and NRAs for a population of 265,000 nurses would clearly indicate a case for over regulation in this country. The structure of regulation of nursing in Australia is a barrier to the changing and evolving role of nurses in the 21st century and a significant factor when considering workforce planning.
