    Uniform Title: Traum und Trauma in Schwarz-Weiß
    Content: Since its inception, U.S. American cinema has grappled with the articulation of racial boundaries. This applies, in the first instance, to featuring mixed-race characters crossing the color line. In a broader sense, however, this also concerns viewing conditions and knowledge configurations. The fact that American film engages itself so extensively with the unbalanced relation between black and white is neither coincidental nor trivial to state - it has much more to do with negating boundaries that pertain to the medium itself. Lisa Gotto examines this constellation along the early history of American film, the cinematic modernism of the late 1950s, and the post-classical cinema of the turn of the millennium

    Content: Tin halide perovskites attract incremental attention to deliver lead-free perovskite solar cells. Nevertheless, disordered crystal growth and low defect formation energy, related to Sn(II) oxidation to Sn(IV), limit the efficiency and stability of solar cells. Engineering the processing from perovskite precursor solution preparation to film crystallization is crucial to tackle these issues and enable the full photovoltaic potential of tin halide perovskites. Herein, the ionic liquid n-butylammonium acetate (BAAc) is used to tune the tin coordination with specific O…Sn chelating bonds and NH…X hydrogen bonds. The coordination between BAAc and tin enables modulation of the crystallization of the perovskite in a thin film. The resulting BAAc-containing perovskite films are more compact and have a preferential crystal orientation. Moreover, a lower amount of Sn(IV) and related chemical defects are found for the BAAc-containing perovskites. Tin halide perovskite solar cells processed with BAAc show a power conversion efficiency of over 10%. This value is retained after storing the devices for over 1000 h in nitrogen. This work paves the way toward a more controlled tin-based perovskite crystallization for stable and efficient lead-free perovskite photovoltaics.

    Content: Este texto aponta algumas das inquietações advindas dos procedimentos de obtenção e interpretação de dados de pesquisa utilizadas na área da sociologia do trabalho. Elas nasceram de uma investigação realizada em conjunto com demais pesquisadores, sobre Trabalho e Qualificação no Complexo Químico Paulista nos anos 1995 e 1998, problematizando as dimensões de gênero e qualificação profissional. Da forma como realizada a investigação partiu de dados quantitativos, para em seguida, buscar a compreensão das práticas e processos que configuravam cada empresa e suas transformações relativas às experiências de trabalho, escolarização, treinamento e uso das qualificações dos trabalhadores. PALAVRAS-CHAVE: Trabalho, métodos de investigação, pesquisa quantitativa e qualitativa, sociologia do trabalho, restruturação produtiva. DATA AND MEANING. SOME METHODOLOGICAL QUESTIONS ON SOCIOLOGY OF WORK This text presents some concerns arising from the procedures for obtaining and interpreting research data used in the sociology of work field. They arise from a survey performed together with other researchers on Work and Qualification in the Paulista Chemical Complex in 1995 and in 1998, calling attention to the problems of gender and professional qualification. The adopted the quantitative data as its starting point, and it then tried to understand the practices and processes that configured each company as well as their transformations referring to the experiences of work, schooling, training and use of workers’ qualification. KEY WORDS: Work, survey methods, quantitative and qualitative research, and sociology of work and productive re-structure Publicação Online do Caderno CRH: http://www.cadernocrh.ufba.br
