Intergenerationality in a Digital World: Proposals of Activities:Bilingual (EN and PT)
A educação para os media tem ganho um grande fôlego nos últimos anos, porém ainda precisa de passos de gigante, muito em especial ao nÃvel da forma como é tratada e enraizada junto dos cidadãos. Este e-book surge com essa preocupação. As fichas de atividades tão diversificadas, todas elas com uma componente digital, embora não esquecendo em alguns casos a ligação a outros dispositivos não digitais e formas de estar na vida no dia a dia. Estas 20 propostas do e-book Intergeracionalidade e o mundo digital: Propostas de atividades/Intergenerationality in a Digital World: Proposals of activities tentam dar forma a uma necessidade que encontramos de fazer com que as pessoas, além das crianças e dos jovens em espaço escolar e no contexto mais formal, questionem, pensem e ajam sobre as interpelações do mundo mediático e da informação.Media Education has gained momentum in recent years, but this area still needs to be improved, especially in terms of how it is perceived and implemented among citizens. This e-book is the result of this concern. The activities are diverse and include a digital component, without forgetting the connection to other non-digital devices in daily life. These 20 proposals of the e-book Intergeracionalidade e o mundo digital: Propostas de atividades/Intergenerationality in a Digital World: Proposals of activities intend to respond to the need that people, besides children in education, question, think and act on the interpellations of a mediatised world full of information available.info:eu-repo/semantics/publishedVersio
Relation between organizational commitment and professional commitment: an exploratory study conducted with teachers
The existence of several kinds of commitments in the workplace is well known. However, there are few studies that relate these different commitments or those established by deterministic models. This study explored the relationship between organizational and professional commitment in public higher education professors according to the multidimensional perspective of Meyer and Allen (1991), based on a convenience sample of 219 teachers. The proposed models were estimated through structural equation modeling methodology. Model 1 specified a relationship of direct influence of Professional Commitment on Organizational Commitment and Model 2 established the opposite relationship of direct influence of organizational commitment on professional commitment. Both models presented a good fit to the data without statistically significant differences between them. Nevertheless, the explanatory power of Model 1 was superior to Model 2, due to the fact that it includes a larger number of determinant relationships that are statistically significant. Theoretical and practical implications were discussed and new directions for future research were identified.info:eu-repo/semantics/publishedVersio
Media Education Competitions: An Efficient Strategy for Digital Literacies?
In this paper we present results from research in Portugal about
competitions in schools that involve digital education (2010-2015). The aim of this
study is to discuss its effectiveness as a strategy for developing Media Education.
The 16 activities we have collected are mostly targeted at the school population and
show an emphasis on media production, a dimension that is often not considered part
of formal learning, which is more focused on reading than on writing. The results
lead us to raise questions about the importance of non-formal education.
Interestingly, most of these initiatives have been designed to take place in the school
context and are, in various ways, supported by the Ministry of Education, a situation
which blurs the boundaries between formal and non-formal learning. The analysis
of the data leads us to this specific recommendation: these initiatives should be
formally evaluated in order to understand their real impact on the acquisition of news

Inherited arc signature in Ediacaran and Early Cambrian basins of
Geochemical data from clastic rocks of the Ossa-Morena Zone (Iberian Massif) show that the main source for the Ediacaran
and the Early Cambrian sediments was a recycled Cadomian magmatic arc along the northern Gondwana margin. The geodynamic
scenario for this segment of the Avalonian-Cadomian active margin is considered in terms of three main stages: (1) The 570–540 Ma
evolution of an active continental margin evolving oblique collision with accretion of oceanic crust, a continental magmatic arc
and the development of related marginal basins; (2) the Ediacaran–Early Cambrian transition (540–520 Ma) coeval with important
orogenic magmatism and the formation of transtensional basins with detritus derived from remnants of the magmatic arc; and (3)
Gondwana fragmentation with the formation of Early Cambrian (520–510 Ma) shallow-water platforms in transtensional grabens
accompanied by rift-related magmatism. These processes are comparable to similar Cadomian successions in other regions of
Gondwanan Europe and Northwest Africa. Ediacaran and Early Cambrian basins preserved in the Ossa-Morena Zone (Portugal
and Spain), the North Armorican Cadomian Belt (France), the Saxo-Thuringian Zone (Germany), the Western Meseta and the
Western High-Atlas (Morocco) share a similar geotectonic evolution, probably situated in the same paleogeographic West African
peri-Gondwanan region of the Avalonian-Cadomian active margin
ARTHROSCOPIC TREATMENT OF POST-TRAUMATIC ELBOW STIFFNESS
ABSTRACTTo evaluate patients undergoing arthroscopic release of a stiff elbow, with discussion of the technique, possible difficulties and risks. Methods: Twenty-four elbow arthroscopy procedures were performed. All the patients were evaluated using goniometry before the operation and six months afterwards and were rated using the Mayo elbow performance score (MEPS). Results: Fifteen men and nine women underwent surgery (14 right elbows and ten left elbows). Their mean age was 34.58 years and length of follow-up, 38.41 months. Their mean gain of range of motion was 43.3° and of MEPS, 85.4. Conclusion: Arthroscopic release might enable better intra-articular viewing and enhance the options for changing strategy during surgery, reducing surgical trauma and enabling early rehabilitation. This technique can reach similar or better results than open surgery. The disadvantages of arthroscopy are the long learning curve and higher cost of the procedure. Neurovascular complications are reported with both techniques. To avoid such problems, the protocol for portal construction must be rigorously followed. Arthroscopic release was shown to be a safe and effective option for achieving range-of-motion gains in cases of post-traumatic stiff elbow
Operaciones de carga y descarga de hidrocarburos terminal refinerÃa s.c. de Tenerife
A fin de documentar al lector y el sector sobre el trabajo que se realiza en la Marina
Mercante, se pone a disposición un estudio que abarca el ámbito de trabajo marÃtimoterrestre. Este puede ser desempeñado con diversas titulaciones, una de ellas la
impartida en la Universidad de La Laguna, sección de Náutica y Transporte MarÃtimo.
El método empleado ha sido, por un lado, trabajando de primera mano en la Terminal
como patrón-operario, por otro, estando embarcado como alumno en prácticas en
buque petro-quÃmico y, además, se ha podido disponer de información adquirida a
través de profesionales con experiencia y con la cualificación necesaria para compartir
sus conocimientos, asà como de libros y manuales oficiales para desempeñar este tipo
de operaciones.
Los resultados y conclusiones más relevantes destacan que, gracias a la titulación
que obtenemos, podremos ser capaces de movernos en un ámbito de trabajo muy
amplio, desde trabajar en tierra hasta operar en un buque de grandes dimensiones y
en diversas terminales. Lo importante es adquirir conocimientos y no detener ese
proceso, siempre evolucionar e intentar estar al dÃa ya que es una profesión que
entraña grandes riesgos. El trabajo para realizar una carga o descarga de combustible
debe ser meticuloso y hace falta de mucha experiencia para ser llevado a cabo. Esta
Terminal es un gran ejemplo de ello, destacada por su historia a lo largo del tiempo
operando con este tipo de buques.In order to document the reader and the sector about the work carried out in the
Maritime Merchant, a study that covers the field of maritime-shore work is made
available. This can be aviable with different qualifications, one of them being the taught
at the University of La Laguna, Nautical and Maritime Transport section.
The method followed has been on the one hand, working at the Terminal as a skipperoperator and, on the other hand, embarked with internship status as deck cadet
onboard a petrochemical ship. Also, the gathering of information obtained through
proffesionals with the necessary qualification to share their knowledge as well as
official books and manuals to carry out this type of operations.
The most relevant results and conclusions highlight that, the degree that we achieve,
will be able to move in a very wide range, from working on shore to operating on a big
LOA ship or at any terminals. The important thing is to acquire knowledges and not
stop doing it process, always evolve and try to keep updated every day because it is a
profession that carries great risks. The work to perform a loading or unloading of fuel
must be meticulous and it takes a lot of experience to do it. This Terminal is a great
example of this highlighted by its history over time operating with this type of vessels
Acessibilidade e deficiência na universidade: polÃtica de recursos humanos
Este trabalho é parte integrante de investigação em rede – com apoio da Capes, no Edital Observatório em Educação (Obeduc) – sobre polÃticas públicas de acessibilidade e inclusão para pessoas com deficiência no Ensino Superior brasileiro. A universidade está despreparada para lidar com a inclusão apesar de existirem muitas polÃticas especÃficas para essa finalidade. O campo escolhido para análise foi uma universidade pública do sistema paulista de Educação Superior e, de acordo com os procedimentos metodológicos traçados – que envolveram releitura crÃtica da bibliografia pertinente, entrevista com gestores universitários, levantamento documental e pesquisa de dados – foi possÃvel verificar grande diferença entre a forma como a esfera pública e a privada tratam o tema da inclusão para pessoas com deficiência. O desafio no caso estudado se amplia em virtude do desconhecimento das especificidades do público-alvo, melhor dizendo, da falta de conhecimento sobre o funcionário público que trabalha na universidade por sua administração superior. Parte-se de pesquisa bibliográfica, entrevista e levantamento de dados. As discussões são balizadas em pressupostos de autores da Educação Especial e da administração pública, além da revisão do amparo normativo da legislação federal e estadual, no caso de São Paulo. Considerações: entre a esfera pública e privada há grandes diferenças ao se tratar o tema inclusão para pessoas com deficiência. Lidar com a inclusão mostra-se um desafio e, no caso da universidade, o problema se amplia em virtude do desconhecimento das especificidades desse público
WOOD QUALITY OF THE SPECIES Cedrelinga cateniformis Ducke THROUGH ULTRASONIC INSPECTION
The present work proposes a method of inspecting structural elements of wood blocks using non-destructive techniques. For this, three blocks of Cedrelinga cateniformis Ducke wood were longitudinally perforated in a grid form, then transversal ultrasound velocities were measured and used to make 2D graphics. Afterwards, the blocks were cut to make transversal specimens that were used to determine apparent densities. The graphs of both parameters were compared to visualize quality zones in the blocks from velocity and density bands. From this, a preliminary inspection protocol using ultrasound tests of structural elements was proposed
Deep autoencoders for acoustic anomaly detection: experiments with working machine and in-vehicle audio
The growing usage of digital microphones has generated an increased interest in the topic of Acoustic Anomaly Detection (AAD). Indeed, there are several real-world AAD application domains, including working machines and in-vehicle intelligence (the main target of this research project). This paper introduces three deep AutoEncoders (AE) for unsupervised AAD tasks, namely a Dense AE, a Convolutional Neural Network (CNN) AE and Long Short-Term Memory Autoencoder (LSTM) AE. To tune the deep learning architectures, development data were adopted from public domain audio datasets related with working machines. A large set of computational experiments was held, showing that the three proposed deep autoencoders, when combined with a melspectrogram sound preprocessing, are quite competitive and outperform a recently proposed AE baseline. Next, on a second experimental stage, aiming to address the final in-vehicle passenger safety goal, the three AEs were adapted to learn from in-vehicle normal audio, assuming three realistic scenarios that were generated by a synthetic audio mixture tool. In general, a high quality AAD discrimination was obtained: working machine data - 72% to 91%; and in-vehicle audio - 78% to 81%. In conjunction with an automotive company, an in-vehicle AAD intelligent system prototype was further developed, aiming to test a selected model (LSTM AE) during a pilot demonstration event that targeted the cough anomaly. Interesting results were obtained, with the AAD system presenting a high cough classification accuracy (e.g., 100% for front seat locations).This work is supported by the European Structural and Investment Funds in the FEDER component, through the Operational Competitiveness and Internationalization Programme (COMPETE 2020) - Project no 039334; Funding Reference: POCI-01-0247-FEDER-039334
