Discutir acerca da formação docente no que tange as questões de ordem tecnológica implica refletir a que tipo de educação se está referindo e para que tipo de sociedade. Conjeturar nessa perspectiva, é compreender que professores não se formam apenas na prática acadêmica, mas também nas práticas sociais diversas e no diálogo constante em sala de aula. Diante disso, convém destacar que a prática docente auxilia a construir uma concepção de tecnologia. Neste sentido, busca-se refletir se a temática "tecnologia" pode trazer subsídios para a formação docente ante a sociedade tecnológica, dialogando com professores formadores, tendo em vista a reflexão crítica desses docentes acerca da temática: "Tecnologia e Educação". Os dados apresentados, neste trabalho, fazem parte do projeto de dedicação exclusiva, por isso se apresentam os resultados de uma entrevista feita com professores formadores com o intuito de refletir sobre conceitos de tecnologia e aplicações de usos tecnológicos. Convém destacar que um dos problemas enfrentados com o uso das tecnologias é a falta de formação do professor para a criação de estratégias que favoreçam o ensino e aprendizagem, além disso, se acredita que se professor tiver disposição em utilizar recursos tecnológicos e tecer discussão acerca de tais usos haveria uma contribuição mais efetiva para o ensino com a mediação tecnológica. Portanto, nesse momento, conclui-se que a incorporação de novas tecnologias pode ser um fator determinante para a vinculação entre os contextos de ensino e as culturas que se desenvolvem fora do âmbito escolar.

Reflexão Crítica AbstractIscussing about the teacher's training regarding the issues on technological order implies reflecting in what kind of education we are referring to and what kind of society. Conjecturing that perspective is to understand that Teachers are not trainedonly in academic practice, but also in different social practices and constant dialogue in the classroom. Therefore, it should be noted that the teaching practice helps to build a design technology. Therefore, it is attemped to reflect if the "technology" theme can provide support for the Teacher's training at the technological society, dialoguing with formative Teachers, in view of the critical reflection of these Teachers on the theme "Technology and Education". In this study, the data, even partial, are part of the exclusive dedication project, so we exhibit the results of an interview with formative Teachers in order to reflect on technology concepts and uses of technological applications. It should be stood out that one of the problems with the use of technology is the lack of Teacher's training in the creation of strategies that enhance teaching, in addition to being believed that if a Teacher had availability to use technological resources and to proposediscussions on such uses there would be a more effective contribution to education with technological mediation. Thus, it is concluded that new technologies incorporation can be a determining factor in the connection between educational contexts and cultures that are develop outside the school environment.

RESUMO: O presente artigo pretende elucidar como a propaganda tem ganhado impulso com as redes sociais. Assim,
trata-se da propaganda por meio das celebridades, as quais aparecem em suas postagens usando certos
produtos e incentivando muitas pessoas a respeito daquele produto. Não é uma estratégia completamente
nova, mas a ideia em destaque é verificar o quanto as redes sociais têm facilitado a exposição dos produtos.
Do mesmo modo que o acesso às redes sociais tem sido cada vez mais predominante, inclusive por empresas,
é importante que o público avalie a presença das marcas em tais redes. Assim, a criticidade no consumo e
assimilação do conteúdo presente nas redes sociais é imprescindível.

PALAVRAS-CHAVE: propaganda, redes sociais, consumo, marcas.

Germination is negatively influenced by water scarcity and by temperatures above or below the optimal range of the species, so it is necessary to know the critical point of absorption for the species or cultivar. The objective of this work was to evaluate the effect of water stress, simulated by solutions of polyethylene glycol 6000 (PEG 6000) at different temperatures, on the germination and vigor of seeds of four cultivars (Branca, Orelha de Vó, Rosinha and Roxinha) of beans (Phaseolus lunatus L.). The water stress simulation was performed using PEG 6000 solutions at concentrations of 0.0, -0.2, -0.4, -0.6, -0.8, -1.0, and -1.2 MPa at temperatures of 25, 30, and 35 ° C. The analyzed variables were percentage of germination at first count, germination speed index, length of aerial part and primary root of seedlings, and dry mass of the respective parts of the seedlings. The seeds of the cultivar Orelha de Vó were more sensitive to water stress, with 88% germinating up to the potential of -0.6 MPa at the tested temperatures. The cultivars Branca, Rosinha, and Roxinha germinated (94, 100, and 100%, respectively) up to the potential of -0.8 MPa. Water stress simulated by PEG (6000) negatively affects seed twinning and seed vigor of bean cultivars.

The present study aimed to verify the prevalence of psychoactive drug use (amphet- amines, methamphetamines, cannabinoids, co- caine, opioids and benzodiazepines) among mili- tary police officers in the state of Goiás. Data were obtained from urine samples voluntarily provided by the officers participating in the study, who were informed of the study methods and signed a free and informed consent form. The samples were subject to screening analysis by immunochro- matography (Multi-DrugOneStep Test®), with positive tests confirmed by gas chromatography– mass spectrometry (GC-MS) and data analyzed by descriptive statistics. The results indicated the presence of the following drugs: amphetamines (0.33%), cannabinoids (0.67%) and benzodiaz- epines (1.34%); 97.66% showed negative results. The positive cases were distributed as follows: benzodiazepines (57.1%); cannabinoids (28.6%) and amphetamines (14.3%). In conclusion, the detection of psychoactive substances in voluntary sampling of military police officers indicates the need to implement drug testing among active mil- itary officers and preventive public policies aimed at eliminating the abusive consumption of psy- chotropic drugs

EPUB and EPDF available Open Access under CC-BY-NC-ND licence. The COVID-19 pandemic has deeply shaken societies and lives around the world. This powerful book reveals how the pandemic has intensified socio-economic problems and inequalities across the world whilst offering visions for a better future informed by social movements and public sociology. Bringing together experts from 27 countries, the authors explore the global echoes of the pandemic and the different responses adopted by governments, policy makers and activists. The new expressions of social action, and forms of solidarity and protest, are discussed in detail, from the Black Lives Matter protests to the French Strike Movement and the Lebanese Uprising. This is a unique global analysis on the current crisis and the contemporary world and its outcomes
