Importance of Polymer Ligand Conformation to the Assembly Behavior of Polymer-Grafted Nanoparticles within 3D-confined block copolymer
No full textImportance of Polymer Ligand Conformation to the Entropy-Driven Assembly Behavior of Polymer-Grafted Nanoparticles within 3D-Confined Block Copolymers
No full textAssembly of hybrid materials with well-defined morphologies is important to design nanomaterials. Here we show a design of entropy-driven particle assemblies with polystyrene-grafted Au nanoparticles (Au@PS) within onion-like polystyrene-b-poly (4-vinylpyridine) (PS-b-P4VP) block copolymer (BCP) particles. Four parameters are investigated: molecular weight (N) and grafting density of PS ligands, core size of Au@PS, and Mn of PS blocks (P). We observed transitions of hybrid particles from alternate-layered onions to crusted onions by controlling these parameters. To account for the phenomena, a modified swelling ratio (P/NSDPB) is proposed by considering the ligands in semi-dilute polymer brush (SDPB) regime as the only brushes available for interfacial interactions with BCPs. The modified parameter successfully explains structural transitions. The findings well demonstrated the importance of ligand conformation to the entropic interactions between block copolymers and grafted polymers

No full textEmpirical investigation of a tradable credits scheme on travel demand: a household utility based approach incorporating travel money and travel time budgets
Get PDFWe investigate the influence of a new mobility management measure, the tradable credits scheme (TCS), on the daily travel mode choices of individuals. Generally, we assume the individuals’ travel consists of different modes, e.g. private car mode and mass transit mode. In order to control the rapid increase in use of the private car mode in an area, policy makers may wish to implement a TCS basing on the VKT (vehicle kilometre travelled). The effects of the TCS are investigated in this paper based on a utility-theory travel demand model proposed by Golob et al. (1981), a household utility based model incorporating proposed travel money and travel time budgets. The empirical investigation is based on comparison studies of the short-term response and long-term effects with and without TCS. It finds that the implementation of TCS has not a clear impact to the value of time of household in the short-term, and the presence of TCS will not affect the linear relationship between travel time budget and travel money budget over long term. Numerical results demonstrate that the TCS will affect the travel distance of the available transport modes differentially, according to different levels of annual household income
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
