The Effect of Clean Water on Long Term Health and Education Outcome: Evidence from Colonial Taiwan between 1909-1933
No full text本文之目的在於探討乾淨用水對一個人長久的影響。利用日治時期所留下的各類統計書, 結合臺閩地區戶口及住宅普查 (1980) 與中老年身心社會生活狀況長期追蹤調查 (1989), 以一個人出生時所在地區的平均千人水栓數當作乾淨用水的指標, 探討胎兒及嬰兒時期的乾淨用水對教育成就、健康狀況、婚姻狀況的影響。此外, 為求解決外生性的問題, 尚以各地區平均每人稅收作為工具變數來進行兩階段最小平方法迴歸 (2SLS)。而無論是否使用工具變數, 乾淨用水的確對教育成就、部分的長期健康狀況、婚姻狀況有顯著正向影響, 特別是在教育成就上, 無論以教育年數、識字、國小畢業、國中畢業、高中畢業或是大學畢業當作衡量教育成就的指標, 皆能看出乾淨用水的正向效果。1 前言................................................................................1 文獻回顧.........................................................................2 資料敘述.........................................................................3 實證結果.........................................................................6 4.1 教育變數、健康變數、婚姻變數與水栓的OLS分析結果.....6 4.1.1 教育成就...................................................................6 4.1.2 長期健康...................................................................8 4.1.3 婚姻狀況...................................................................9 4.1.4 短期健康...................................................................9 4.2 工具變數分析..............................................................10 4.2.1 OLS內生性之探討與工具變數之決定...........................10 4.2.2 第一階段迴歸結果.....................................................11 4.2.3 第二階段迴歸結果.....................................................12 結論..............................................................................13考文獻..........................................................................1
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
An empirical analysis on determinants of demand for best sellers: \ue2Books\ue2 online book store
No full textThe study empirically investigates the factors, including book-specific characteristics and book information on user interface, affecting demand for best-selling books, and the determinants of book price. By using random sampling approach, 1831 books were selected from \ue2Books\ue2 online book store; we used logistic regression to analyze these data. The results show that foreign books and more words for recommendation tend to be best sellers; in addition, the results also indicate the books that were made into movies or games, winning the literally prize, and more Taiwanese celebrities recommendation have positive and significant effect on the probability of being the best sellers. We also found that famous author without introduction on interface have higher probability as best sellers. Though the words for book introduction is not significant in the model, its interaction with online search times of the author is significant. Moreover, we found that cost of books is the major factor influencing price
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
