Construindo um modelo de streaming no Brasil?: uma breve análise do globoplay

As plataformas de streaming estão cada vez mais presentes na sociedade. Os Estudos de Plataforma indicam que devemos evitar o termo “impacto tecnológico” para descrever esse atual momento, pois vivenciamos um complexo emaranhado de algoritmos e práticas que remodelam as ações dos consumidores. Verificando a construção de um modelo de streaming no Brasil, voltamos nosso olhar para o Globoplay, uma plataforma brasileira criada pelo Grupo Globo, em 2015. Com o intuito de compreender como vem sendo inserido o modelo no país, observamos tal serviço de streaming por meio das perspectivas teóricas abordadas por Santaella (2013); Ladeira (2016); Parker, Alstyne, Choudary (2016); e d’Andréa (2020).Constructing a streaming model in brazil?: a short analysis of the globoplay platformAbstractStreaming platforms are increasingly present in society. Platform Studies indicate that we should avoid the term “technological impact” to describe this current moment, as we experience a complex tangle of algorithms and practices that reshape consumer actions. When verifying the construction of a streaming model in Brazil, we observe Globoplay, a Brazilian platform created by Grupo Globo in 2015. In order to understand how the model has been built in the country, we observe such streaming service through theoretical approaches addressed by Santaella (2013), Ladeira (2016), Parker, Alstyne, Choudary (2016) and d'Andréa (2020).Keywords: Audiovisual; streaming; platform studies; Brazil; Globoplay.

3D-Printed Miniature Robots with Piezoelectric Actuation for Locomotion and Steering Maneuverability Applications

The miniaturization of robots with locomotion abilities is a challenge of significant technological impact in many applications where large-scale robots have physical or cost restrictions. Access to hostile environments, improving microfabrication processes, or advanced instrumentation are examples of their potential use. Here, we propose a miniature 20 mm long sub-gram robot with piezoelectric actuation whose direction of motion can be controlled. A differential drive approach was implemented in an H-shaped 3D-printed motor platform featuring two plate resonators linked at their center, with built-in legs. The locomotion was driven by the generation of standing waves on each plate by means of piezoelectric patches excited with burst signals. The control of the motion trajectory of the robot, either translation or rotation, was attained by adjusting the parameters of the actuation signals such as the applied voltage, the number of applied cycles, or the driving frequency. The robot demonstrated locomotion in bidirectional straight paths as long as 65 mm at 2 mm/s speed with a voltage amplitude of only 10 V, and forward and backward precise steps as low as 1 µm. The spinning of the robot could be controlled with turns as low as 0.013 deg. and angular speeds as high as 3 deg./s under the same conditions. The proposed device was able to describe complex trajectories of more than 160 mm, while carrying 70 times its own weight.

Science Forum: Building a community to engineer synthetic cells and organelles from the bottom-up

Employing concepts from physics, chemistry and bioengineering, 'learning-by-building' approaches are becoming increasingly popular in the life sciences, especially with researchers who are attempting to engineer cellular life from scratch. The SynCell2020/21 conference brought together researchers from different disciplines to highlight progress in this field, including areas where synthetic cells are having socioeconomic and technological impact. Conference participants also identified the challenges involved in designing, manipulating and creating synthetic cells with hierarchical organization and function. A key conclusion is the need to build an international and interdisciplinary research community through enhanced communication, resource-sharing, and educational initiatives.

Precision Medicine: Technological Impact into Breast Cancer Diagnosis, Treatment and Decision Making

Breast cancer is the most common cancer in women, impacting 2.1 million women each year. The number of publications on BC is much higher than for any other type of tumor, as well as the number of clinical trials. One of the consequences of all this information is reflected in the number of approved drugs. This review aims to discuss the impact of technological advances in the diagnosis, treatment and decision making of breast cancer and the prospects for the next 10 years. Currently, the literature has described personalized medicine, but what will the treatment be called for in the coming years?

TEACHER THEORY AND ADAPTABLE MODEL: AN APPLICATION TO TEACHING PROFESSION

<p>The application of teaching profession in the teacher theory and adaptable model defines a teaching work and features that involves the change, novelty, and daily basis of uncertainty. The change is effectively a response to the necessary adaptability among teachers in their function and healthy effectiveness in their work. It assesses the various approaches and adaptability to describe the practice and implication on the development of teachers’ relevance to the knowledge for further experiences. It provides adaptability and technological impact and change in the teaching process. On the other hand, the teacher theory and adaptable model in the application of the teaching profession refers to the following acronym, T stands for Talent, E stands for Enthusiastic, A stands for Adaptable, C stands for Creative, H stands for Honest, E stands for Effective, and R stands for Resourcefulness where the approach and the process consider teaching and learning perspective manner considering the student performance in the learning process. The teaching provides rich knowledge of the profession of teachers as specialists in molding and shaping the future of students in their professional fields. Moreover, the teacher theory and adaptable model cycle highlights the characteristics and features of expert teachers to include content knowledge, extensive pedagogy, diverse learners, adaptation, problem solving strategies and techniques, decision making, event classroom perception, context sensitivity, and respect for students. It stresses the knowledge that holds teachers in the academic assimilation and highlights knowledge in the classroom practical experiences. Furthermore, the application of the theory and adaptable model in the teaching profession is very essential in the structure and understanding the domain of learning and teaching as to affective, cognitive, and psychomotor domains in different approaches of teaching as to student reinforcement and learning guide, make relevant learning meaningful, foster learning, self-direction, and incorporate interes t and prior learning knowledge.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0974/a.php" alt="Hit counter" /></p>

New technologies and new paradigms: the new technological societies approach

New technologies represent novelty depending on the era in which they are viewed, but in all cases they represent social evolution in some way. At present, new technologies are associated with the use of computer tools that strengthen processes, mechanisms, and undoubtedly, social communication. This paper evaluates new technologies focused on social transformations, their impact on human behavior and the social repercussions they may bring with their prevalence over time. Several academic documents of a scientific and technical nature are evaluated, with a view to defining the paradigms of technologies in their evolutionary process through societies. The most outstanding results show that the modern world is subject to a significant impact of information technology, that it encompasses not only educational aspects but also family, personal and economic aspects, and that the implications of traditional substitution by technology may be detrimental to mankind.
