Tunneling path toward spintronics
No full textThe phenomenon of quantum tunneling, which was discovered almost a century ago, has led to many subsequent discoveries. One such discovery, spin polarized tunneling, was made 40 years ago by Robert Meservey and Paul Tedrow (Tedrow and Meservey 1971 Phys. Rev. Lett. 26 192), and it has resulted in many fundamental observations and opened up an entirely new field of study. Until the mid-1990s, this field developed at a steady, low rate, after which a huge increase in activity suddenly occurred as a result of the unraveling of successful spin tunneling between two ferromagnets. In the past 15 years, several thousands of papers related to spin polarized tunneling and transport have been published, making this topic one of the hottest areas in condensed matter physics from both fundamental science and applications viewpoints. Many review papers and book chapters have been written in the past decade on this subject. This paper is not exhaustive by any means; rather, the emphases are on recent progress, technological developments and informing the reader about the current direction in which this topic is moving
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
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
( 皇朝經世文編) 學術、治體部分思想之分析
No full text[[abstract]]鴉片戰爭前十四年（一八二五）魏源（一七九四─一八五七）應賀長齡（一七八五─
一八四八）之邀，蒐集清初至道光年間的文章兩千餘篇，經過精心構思與剪裁之後，
編成《皇朝經世文編》一書。該書為道光時期經世思想的代表著作，對當代知識份子
造成深遠的影響。
本文主旨即欲藉著分析《皇朝經世文編》一書中學書、治體部分，探討二個彼此相關
且部分重覆的問題：第一，如果以鴉片戰爭以後的時間作為中國現代化的起點，則在
現代化前夕中國知識份子的價值取向（Value Orientation ）是什麼？第二，道光時
期經世思想的基本內涵是什麼？
本書分五章，約二十萬字。
第一章導論。本章為問題的提出與研究方法之設定。在研究方法方面，本文認為思想
或價值取向是一個動態的過程而非靜態的信仰，它包含一些共同討論的議題（agened
a ），以及許多不同的回答。本文的分析方式，即找出《文編》學術、治體部分各文
章所關心的問題，以及對每個問題提出的可能答案。
第二章背景。本章分別敘述《文編》思想的社會背景與思想背景。
第三章《文編》學術、治體部分思想之內涵。本章文全書之主體，我們分別從「知識
的來源」、「現實世界的基本組成與活動」、「目標」、「對歷史的看法」、「濟世
之策」、「經世思想家對目標、障礙和濟世之策的綜合評估」等項描繪道光時期經世
思之基本內涵。
第四章《文編》學術、治體部分思想之特點。本章綜合上述思想之內涵，透過「轉化
─調適」的分析架構觀察其特點。所謂「轉化思想」意指重視理想並主張徹底改革的
思想傾向；「調適思想」則為重視現實並主章逐步改良了的思想傾向。根據本文的分
析，道光時期經世思想既非完全轉化亦非完全調適，而是兼具兩者的特色，亦即以調
適思想為主流，轉化思想為伏流。它一方面肯定現實狀況，針對各種缺失作局部的調
整，另一方面也具有超越的理想，希望徹底改造世界。
第五章結論。本文認為上述道光時期經世思想之基本內涵與特點，可以視為現代化前
夕中國知識份子價植取向的重要部分，許多知識份子就帶著這樣的價值取向邁入現代
化。因此，本文的研究雖然尚未觸及傳統與現代化時期思想之連續性問題，但是如果
以本文為基礎，再運用同樣的分析架構進一步探討現代化思想之特色，我們就可以更
深入地了解傳統與現代化時期之連續性。
