Mídias na educação e formação de professores: por uma convergência dialógica

The article presents an analysis of media in education from a gaze that seeks convergence in dialogic relationship between teachers and the media resources. This study objective is to question the knowledge necessary to teacher training with a view to intentional use, conscious and mediator of media in education, considering technology as an effort of human beings in their self-production in addition to the biological resources that are provided, but this effort the technology assumes nuances that are associated with the purpose of its use. Therefore, its use is not neutral, rather, meets the purposes of those who use them, or that it plans to use. The study was guided by the literature among other references, the studies of Pierre Levy (1999, 2011), contributing to generating technophilia and technophobia of Pedro Demo (2009), dialogue as historicizing process and basis for teacher training from Paulo Freire (1991; 1996), the immersion of the changes with the technological acceleration and the need for critical counterpoint technique, proposed by Nicholas Sevcenko (2001), teaching as interactive work from Tardif (2010) among other references. The results show convergences dialogic possibilities in the use of technological resources by teachers

Relações entre tabagismo, fatores associados e densidade mineral óssea em mulheres de meia-idade / Relationship between smoking, associated factors and bone mineral density in middle women

O objetivo deste estudo foi avaliar as relações entre tabagismo e fatores associados na densidade mineral óssea em mulheres de meia-idade não tabagistas, ex-tabagistas e tabagistas. Trata-se de investigação não experimental de método e procedimentos próprios da pesquisa epidemiológica analítica. Participaram desta investigação 78 mulheres com idade entre 45 a 75 anos, distribuídas em três grupos: indivíduos não tabagistas (41), ex-tabagistas (18) e tabagistas (21). Àquelas que concordaram em participar do estudo assinando o Termo de Consentimento Livre e Esclarecido foi aplicado o teste de Fagerström, para avaliar a dependência nicotínica. Foi realizado, ainda, exame de densitometria por emissão de raios X de dupla energia, que avaliou a densidade mineral óssea do fêmur total. Foi considerado p?0,05 como significância estatística. O escore médio 3,21±1,14 representou grau baixo de dependência nicotínica para o grupo em geral. Em relação ao segmento fêmur total, o tabagismo foi determinante na explicação da osteoporose, com diferenças estatisticamente significantes. Não tabagistas ainda apresentaram melhores condições gerais de saúde. Além disso, os tabagistas avaliados apresentaram maiores perdas percentuais de densidade mineral óssea em todos os segmentos investigados do que as prevalências em não tabagistas no cenário nacional. No entanto, o tamanho de nossa amostra e a coleta de dados em apenas um centro de referência clínica limitaram as conclusões, abrindo no horizonte extensa agenda de investigações desejáveis à consolidação do entendimento entre tabagismo e massa óssea

The activity of laurel essential oil (crude and fractions) in the control of adult bovine ticks and larvae

Ectoparasites cause direct and indirect losses to farmers, affecting the production of meat and milk and increasing the production costs due to the acquisition of acaricides to maintain cattle health. The financial losses caused by Rhipicephalus (Boophilus) microplus, which is the main livestock ectoparasite in Brazil, reach approximately US$ 3 billion annually. The aim of this study was to evaluate the acaricidal effect of the crude essential oil (EO) and EO’s fractions (FR) obtained from Laurus nobilis L. (Lauraceae) leaves on Rhipicephalus (Boophilus) microplus. Eight fractions were obtained, wherein five major compounds were identified (sabinene, α-terpinyl acetate, 1,8-cineole, linalool, and α-terpineol). The acaricidal activity of these FR was tested by the larval packet test. The EO was tested by the adult immersion test, and, at concentrations of 200, 100 and 50 µL/mL, the oil caused mortality of engorged females, egg mass reduction, and hatching inhibition. The fractions with α-terpineol and sabinene, as the major compounds, were the most active larvicides (LC50=0.13 µL/mL, LC99=0.51 µL/mL; and LC50=0.20 µL/mL, LC99=0.56 µL/mL, respectively). This assessment also indicated that fractionation was important since most of the fractions obtained were more active than the EO. Furthermore, this is the first report of laurel EO and its fractions employed in the control of cattle ticks. Thereby, new prospects for the use of this essential oil or its chromatographic fractions in products applied for cattle tick control can be opened up. However, studies in other stages of development of cattle ticks for the active fractions, and studies under field conditions, the effect on non-target organisms and residual effect on the environment are still needed to evaluate the acaricidal activity of EO and its active fractions

Genomic history of coastal societies from eastern South America

Sambaqui (shellmound) societies are among the most intriguing archaeological phenomena in pre-colonial South America, extending from approximately 8,000 to 1,000 years before present (yr bp) across 3,000 km on the Atlantic coast. However, little is known about their connection to early Holocene hunter-gatherers, how this may have contributed to different historical pathways and the processes through which late Holocene ceramists came to rule the coast shortly before European contact. To contribute to our understanding of the population history of indigenous societies on the eastern coast of South America, we produced genome-wide data from 34 ancient individuals as early as 10,000 yr bp from four different regions in Brazil. Early Holocene hunter-gatherers were found to lack shared genetic drift among themselves and with later populations from eastern South America, suggesting that they derived from a common radiation and did not contribute substantially to later coastal groups. Our analyses show genetic heterogeneity among contemporaneous Sambaqui groups from the southeastern and southern Brazilian coast, contrary to the similarity expressed in the archaeological record. The complex history of intercultural contact between inland horticulturists and coastal populations becomes genetically evident during the final horizon of Sambaqui societies, from around 2,200 yr bp, corroborating evidence of cultural change

MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal

Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.
