    Return migration is the positive counterpart of brain drain. Human capital accumulation increases in a country if skilled agents go back home after a period spent working abroad. Effects of brain drain in Italy could be negative as highly skilled migrants decide not to come back to their native country. Our simple model shows that if preference for home consumption is balanced by career opportunities and life-style conditions, agents leave Italy and prefer to remain abroad. Data support and policy implications are provided.Return migration; brain drain.

    Pecan nutshell is a residue from food industry that has potential to be used as biopreservative in foods. The objective of this study was to evaluate the antimicrobial activity of pecan nutshell aqueous extract in vitro and its effectiveness to inhibit spoilage microorganisms on lettuce leaves. The results indicate that the aqueous extract presents inhibitory activity against important foodborne pathogenic bacteria such as Listeria monocytogenes, Salmonella Enteritidis, Staphylococcus aureus, Bacillus cereus, Aeromonas hydrophila and Pseudomonas aeruginosa. Antimicrobial activity was not observed against Corynebacterium fimi, Clostridium perfringens, Escherichia coli, and the phytopathogenic fungi tested. When applied onto lettuce leaves, pecan nutshell extract reduced the counts of mesophilic and psychrotrophic bacteria in 2 and 4 log CFU/g, respectively, during storage of leafy for 5 days at refrigeration temperature (5 °C). The extract was not effective to inhibit yeast on lettuce leaves. Thus, the aqueous extract of pecan shell showed great potential to be used as a natural preservative in foods, acting mainly in the inhibition of spoilage and pathogenic bacteria. © 2016, Sociedade Brasileira de Ciencia e Tecnologia de Alimentos, SBCTA.

    #Matheusa no twitter: enquadramentos e negação do sujeito trans

    O trabalho apresenta resultados de pesquisa realizada no Twitter acerca do caso #Matheusa Passareli, estudante de 21 anos da Universidade Federal do Rio de Janeiro, ativista LGBTQI+, que se posicionava como não binária e foi brutalmente assassinada em abril de 2018. Analisamos comentários em tweets e retweets sobre o caso feitos via @bbcbrasil, que em grande parte evidenciaram posturas reacionárias sobre gênero e sexualidade. Trata-se de pesquisa etnográfica na internet, cujas reflexões são construídas com base em estudos sobre performatividade do gênero e teoria Queer (BUTLER, 2003; LOURO, 2003), sobre a dimensão sociopolítica e ideológica de identidades em interações (MOITA LOPES, 2010; BIONDO E SIGNORINI, 2015) e sobre enquadramentos interacionais (GAMSON, 1992; ENTMAN, 2007). Nas interações analisadas, há enquadramentos da afirmação binária do gênero se sobrepondo à preocupação com o crime e com a crueldade do assassinato. Além disso, a subversão ao binarismo aparece como uma possível justificativa para o assassinato, evidenciando a abjeção de sujeitos que ousam subverter as normas tradicionais do gênero
