Advanced Side-Impermeability Characteristics of Fluorinated Organic-Inorganic Nanohybrid Materials for Thin Film Encapsulation
No full textIn this study, we introduce a sol-gel based fluorinated nanohybrid materials named FAGPTi to fabricate organic-inorganic hybrid thin film encapsulation (TFE) with plasma-enhanced atomic layer deposition (PEALD)-based Al2O3 for optoelectronics. A systematic analysis of the FAGPTi film on various substrates reveals that the FAGPTi films fully covered all parts of the substrate, showing low roughness, high hydrophobicity, and good flexibility. These results demonstrate that FAGPTi is able to protect water corrosive Al2O3 from the outer invasion of moisture or water. Therefore, the TFE with alternatively stacked Al2O3 and FAGPTi shows excellent barrier film performance as low as 6.33 �� 10?5g m?2 day?1s at accelerated conditions (60 ��C and 90% RH) and high visible transmittance above 95% in four pairs. In particular, the FAGPTi films displayed advanced side impermeability, with values comparable to those of the oxide layer. Thus, we expect our systematic work with FAGPTi layers to provide insights into barrier films to advance their integration in flexible optoelectronic devices and thereby accelerate their commercialization.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
