Multi-choice Goal Programming for Portfolio Selection
No full text本研究旨在探討投資人的最適投資組合決策，採用Muti-choice goal programming (MCGP)方法，考慮基本面、技術面及籌碼面等投資準則，及投資人對該準則的期望準位，以發展成最適投資組合決策之模式，其重要結論如下：、運用MCGP的方法所設定的投資模型，可以改善Goal Progrmming (GP)模型在投資決策上對於多準則及多目標無法求解的狀況。、運用MCGP的投資模型，對於內在主觀的感受，可以透過期望準位(aspiration level)的設定，將存在內心的屬性客觀的表現出來。、投資人對於內在主觀的感受，可以長期的試驗及追蹤，了解自己的投資屬性，並且可以在不同的經濟環境下模擬選股結果，亦可以避免非理性的情緒影響投資決策。、運用MCGP投資模型兼具模仿與自我學習效果，投資人隨著本身的經濟狀況、知識及經驗的成長，可以利用MCGP的投資模式來調整適合自己的投資準則及期望準位，提升投資組合的報酬率。、對基金經理人或證券分析師而言，可針對顧客屬性提供適合的投資建議，減少投資糾紛。MCGP模型可以同時評估不同投資準則，足以達到選股及擇時皆考慮的效果，增加獲利的機會。、MCGP模型可以針對不同類型投資人的需求，滿足對於指標選擇的彈性。並可運用工具軟體建置於網路上，證券業者可以使用MCGP模型增加與潛在客戶的互動，進而增進業務績效。This study aimed at the investment portfolio decision-making optimum by using Multi-choice Goal Programming (MCGP). The MCGP optimal portfolio decision-making model is concerning fundamental analysis, technical analysis, institutional analysis, and investors’ aspiration level. Its important conclusions are as follows:. The MCGP investment model applied for portforlio seletion can improve the weakness that GP model can not solved multi-crieterion and multi-objectives problems in the portforlio seletion decisions.. Through MCGP investment model, the inner subjective feelings of investors can be objectively expressed by setting different aspiration level.. Investor’s inner subjective feelings can be long-term track and be tested to understand their investment properties. In addition, in different economic environment it can simulate to choose stock results.. In the future, using investors’ own understanding on economic situation, knowledge and experience; they can use MCGP model to adjust their criteria or aspiration level. . Investors can use the set MCGP investment model to avoid the emotional impact of irrational investment decisions. . MCGP investment model can be used for different types of investors’ demands to meet the optimum portfolio selection chosen for the flexibility. . The analyst can use to provide investment recommendations to reduce investment disputes for customers.口試委員會審定書 i謝 ii文摘要 iii文摘要 iv錄 v目錄 vii目錄 viii壹章 緒論 1一節 研究背景與動機 1二節 研究目的 2三節 研究範圍與限制 2四節 論文架構 3貳章 文獻探討 5一節 投資理論 5二節 目標規劃理論 15參章 研究方法 19一節 決策模式的建立與比較分析 20二節 研究流程 22三節 個案分析 24肆章 決策模式的建立與分析 25一節 決策模式的建立 25二節 實驗資料數據的建立與決策模式的模擬 30三節 模式解值的分析與比較 39伍章 結論與建議 52考文獻 55、中 文 部 分 55、英 文 部 分 56 錄 57 附錄一：最新技術指標在台灣股市應用的訣竅……57 附錄二：樣本篩選:台灣50(0050.TW)成份股…………………59 附錄三：不同種類投資人的期望準位設定………………………61 附錄四：個案資料表………………………………6
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
