Book Review of AI Superpowers: China, Silicon Valley, and the New World Order by Kai-Fu Lee
Full text linkDr. Kai-Fu Lee’s book, AI Superpowers: China, Silicon Valley, and the New World Order, can be characterized as a glimpse of how humankind could coexist with artificial intelligence, that would render many people unemployed. The book also hints at the AI power game between the United States and China. The author claims China will be the victor due to a deeper understanding of how to implement AI technologies, as opposed to simply developing them.
I believe that the skillful application of AI will be China\u27s greatest opportunity to catch-up - and probably surpass - the United States. But more importantly, this shift will create an opportunity for all people to discover what it is that makes us human.
Dr. Kai-Fu Lee
Do we live in the age of great discoveries or the age of implementation? According to Dr. Lee, the founder and president of Sinovation Ventures Artificial Intelligence Institute, the opportunities of AI such as driving a car, diagnosing diseases, and the ability to do spoken translation between different languages, do not signify rapid progress toward \u27general AI\u27 any other similar breakthrough on a level of deep learning. Rather these constitute an implementation, just like applying electricity to lightning, the dwelling, and powering the industry

AI superpowers ::China, Silicon Valley, and the new world order /
No full text"Kai-Fu Lee--one of the world's most respected experts on AI and China--reveals that China has suddenly caught up to the United States at an astonishingly rapid and unexpected pace. In AI Superpowers, Kai-Fu Lee argues powerfully that because of the unprecedented developments in artificial intelligence, dramatic changes will be happening much sooner than many of us have expected. Indeed, as the U.S.-China competition in AI begins to heat up, Lee urges America and China to both accept and embrace the great responsibilities that come with significant technological power. Most experts already say that AI will have a devastating impact on blue-collar jobs. But Lee predicts that Chinese and American AI will have a strong impact on white-collar jobs as well. Is universal basic income the solution? In Lee's opinion, probably not. But he provides a clear description of which jobs will be affected and how soon, which jobs can be enhanced with AI, and, most important, how we can provide solutions to some of the most profound changes in human history that are coming soon."--Jacket
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

Can Backdating Explain the Abnormal Returns around Taiwanese Employee Stock Option Grants?
No full text此實證研究一窺在美國與加拿大政府機關與學術界受到廣大關注的回溯日期手法，而我們也嘗試去分析回溯日期手法是否可能發生在台灣。樣本採用台灣上市與上櫃公司在2001至2006年12月7日的員工認股權，我們發現在給予日之前股價會逐漸下跌，給予日之後股價會迅速且明顯的上漲。非常有趣地此異常報酬率的模式與美國或加拿大所發現的結果非常類似。我們發現當公司規模較小、員工認股選擇權計劃受經理人或家族集團控制、認股權股數較多，高階經理人有能力及動機去影響給予日的時間點，所以給予日附近的異常報酬也會更明顯。分析台灣的法規、實務、與此實證結果後，我們認為回歸日期的手法也可以解釋台灣員工認股選擇權在給予日附近的異常報酬率。This study takes a glimpse of the backdating practices capturing plenty of attention of academics and policy makers in U.S. or Canada, and we also try to analyze whether backdating could also take place in Taiwan. Using the sample of Taiwanese employee stock option awards among TSE(Taiwan Stock Exchange) listed and OTC firms firm 2001 to Dec 7th 2006, we find that stock prices fall gradually before the option grant dates and surge significantly following the grant date, generating sharp reversal of abnormal stock returns. Interestingly the abnormal return pattern around the grant date is very similar to American and Canadian ones. We also find when executives have the incentive (i.e., more shares granted) and the ability (such as poor corporate governance, employee stock option plan influenced by top managers or family group) to influence the timing of employee stock option grants, the abnormal return pattern would be more discernible. Our research indicates that backdating could also explain Taiwanese abnormal returns around employee stock option grantsAcknowledgement I

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
