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

No full textM.Phil.Stationary Turing patterns can be observed in quantum well microcavities when they are pumped with a normally incident laser. Stable symmetric and asymmetric Turing patterns have been studied in a reduced momentum space model [M. H. Luk et al., Phys. Rev. B 87, 205307 (2013)]. However, some recent studies showed that some of these stable Turing pattens will start to collapse soon after the patterns is formed.In this thesis, we focus our analysis on the stability of different types of patterns formed in a quantum well microcavities pumped by a normally incident laser. In a reduced momentum space model, we show theoretically that oscillating patterns can be formed when the pump intensity reaches certain value. In these oscillating patterns, two interesting features, including the Hopf-bifurcation and the period doubling, could be observed. On the other hand, by using an extended momentum space model, we show how a stationary pattern starts to collapse under certain condition, present a time domain simulation to demonstrate the collapse, and compare the results with the studies on the real-space model.Last, we also study the low intensity all-optical switching, including switching time study and intensity optimization.當激光垂直照射在半導體微腔時，靜止的光學圖案能夠被觀察到。這些穩定的靜止光學圖案，不論是否對稱，都曾在不完整的動量空間被細仔研究過。但在最近的研究指出，一部份這些光學圖案在形成後會開始變得不靜止，甚至整個光學圖案會崩潰。本論文研究了在激光垂直照射半導體微腔情況下，不同光學圖案的穩定性。在不完整的動量空間，我們在理論上展示了當激光的強度達到一定數值時，振動的光學圖案能夠被觀察得到。而這些振動的光學圖案中，我們發現了一些有趣的現像，包括霍普夫分岐和週期倍增。另一方面，在完整的動量空間上，我們展示了在特定的情況下，一個光學圖案怎樣由靜止去到崩潰，當中包括穩定性研究和模擬過程；這些結果會與二維現實空間的模型進行比較。最後，我們還研究了振動的激光強度產生的光學圖案；低強度全光學開關，當中包括開關所需時間和激光強度最優化。Tsang, Chun Yin = 半導體中微腔中圖案形成動力學 / 曾俊彥.Thesis M.Phil.

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
