The three elements of hypertext: Constructing digital artistry and rebooting possible lives—Take the Cheng Guang work “Life Reboot” as the center of inspection
Get PDFThe core characteristic of new media literature that differs from traditional print-era literature can be summarized as “digital artistry”. Based on the Cheng Guang interactive platform, the Cheng Guang literature adopts a typical hypertext model and shows a certain degree of representativeness in the creation of digital artistry. Life Reboot fully utilizes the constructive functions of the three elements of hypertext—node, link, and network—to produce aesthetic effects that are different from those of traditional literary works—digital artistry such as composite symbolic text, interactive narrative, and ontolepsis. The use of the three elements of hypertext enables readers to break through the limitations of reality, travel through multi-dimensional space and “parallel universes”, realize a life reboot, reach multiple possible lives, and obtain aesthetic experiences that traditional literary works cannot provide
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
线性、径向和环向偏振飞秒激光诱导非晶合金周期性表面结构
No full textThe formation mechanism of Laser Induced Periodic Surface Structures (LIPSS) on the amorphous alloy Zr44Ti11Cu10Ni10Be25(at%) was investigated. In experiment, LIPSS on the amorphous alloy were produced by ultrashort laser pulses of 120 fs duration at 800 nm wavelength in three types of laser polarizations (linear, radial and azimuthal polarization). These LIPSS are comprised of Low;Spatial;Frequency LIPSS (LSFL) with the periodicity of 652~723 nm and macro;ripples with the periodicity of 1 304~1 765 nm. By Finite;Difference Time;Domain (FDTD) simulations, formation mechanism of macro;ripples can be explained by the interference between laser and modulated scattered electromagnetic wave induced by rough surface. In the condition of three types of laser polarizations (linear, radial and azimuthal polarization), FDTD simulation results agree with experimental results, proving the effectiveness of the macro;ripple formation mechanism. © 2016, Science Press.

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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
