A complexa cultura contemporânea faz emergir expressões através deinúmeras dinâmicas midiáticas, revelando o entretenimento não apenas comoconteúdo de distintas indústrias – música, cinema, literatura, games etc – mas como linguagem que permeia, agora, toda a sociedade. Assim, mesmo aquelessetores que pareciam os mais avessos ao entretenimento – como a educação, apolítica e a religião, por exemplo – passam agora a adotá-lo para tornar maiseficiente seus processos comunicacionais. É dentro dessa perspectiva, com oobjetivo de explorar a hibridização entre cultura, entretenimento e (...) práticasmidiáticas, que o presente número da Logos propõe o dossiê Comunicação eEntretenimento: Práticas Sociais, Indústrias e Linguagens.

The expression that professionals should be led by their moral or ethical compass is increasingly used by academics, policy makers, professionals, and educational institutes. Dutch universities of applied sciences (UAS), for example, explicitly aim to educate their students to become professionals equipped with a moral compass. This moral or ethical compass is a metaphor of which people intuitively grasp its meaning, but our literature review also shows that various interpretations are possible. We found three clusters of proposed ethical compasses expressing (...) its a) content, b) form, or c) use, which we present in this article. Thereafter, we evaluate which compass can meaningfully assist (young) professionals and, therefore, should be part of the aims and content of education provided by UAS. Based on this evaluation, we describe the possibilities and boundaries of UAS’ contribution to the development of their students’ ethical compass. (shrink)

Science is as much defined by the local “instrumentarium,” the equipment available to an experimenter at a particular time and place, as by its discoveries and theories. Instruments are devices for detecting and measuring natural phenomena, linked causally to those aspects of nature they are used to record. Some are inorganic, made of glass and metal, while others are organic, the bodies and body parts of living or once living plants and animals. In contrast, pieces of apparatus are quite (...) different in the ways in which they work. They too can be organic or inorganic, but their role is to model things, process, structures, and so on in the natural world. They are used to study natural processes by simulating them in a user-friendly way. Keeping the distinction between instruments and apparatus in mind is crucial to understanding the power of the experimental method. (shrink)

In a market place crowded with practical rhetoric books what educational value could a challenging work such as Kenneth Burke’s A Rhetoric of Motives possibly have? Burke knows but doesn’t use the terminology of the classical art and rather than analysing the persuasive rhetoric of well-known speeches to equip us with strategies, he weaves his way around literary texts, teasing out meanings that their authors something intended, sometimes did not. Yet, despite such difficulties, A Rhetoric of Motives is a practical (...) rhetoric book. It is just that its process of explication teaches us to think well. This essay tries to explain Burke’s rethinking of the purpose and contents of a traditional teaching tool—the rhetorical handbook—and defends the value of literary-rhetorical reading that aims to ‘equip’ citizens to think openly.

Aiming to realize rapid and efficient three-dimensional identification of substation equipment, this article proposes a new method in which the 3D identification of substation equipment is based on K-nearest neighbor classification of subspace feature vector. First of all, the article uses octree encoding to reduce and denoise the point cloud data obtained by a 3D laser scanner. Secondly, position calibration and size standardization are used for the point cloud after pretreatment. Then, the normalized point cloud is divided into (...) a number of cubes with same size. The cosine of the angle between the positive direction of z axis and a vector from the global centroid of the point cloud to the centroid of each subspace is regarded as the feature of the subspace. All cosines of subspaces constitute the feature of the point cloud. Finally, we classify the subspace feature vector by using the KNN algorithm and improve classification accuracy by using the particle swarm optimization algorithm. The simulation results show that the identification accuracy of the proposed method for unknown substation equipment is about 90% and the proposed method is applicable to low-degree losses. Apparently, this method can accurately identify 3D substation equipment. At the same time, increasing the number of subspaces will improve the accuracy; however, it will increase the recognition time. (shrink)

A major challenge for education policymakers and educators globally is the strong and persistent impact of student socio-economic status on learning. This is a challenge that will not be addressed solely by school-focused reform. However, one policy initiative that could make a positive difference in this regard, and could bring other benefits to schools and communities, is equipping schools to act as hubs for a range of social and health services for their students, families, and communities. Schools as community hubs (...) can not only act to mitigate the impact of poverty on learners, but can position schools at the centre of communities, and build community resilience and capacity.
