The development of a grinder BOM relational data by the use of quality function deployment concept
No full text 關聯式資料庫在建立資料間關係上，資料模型化能力弱，無法記錄一個複雜的資料結構，若要描述物件與物件之間的複雜關係，必須另外建立一個表格處理，當資料量越來越多時，必須額外新建更多的表格才足以應付需求，並且在描述物件間的關係上，欠缺系統性的方法，通常依資料庫設計者的經驗、方法及知識水準不同而有所差別。
為了改善關聯式資料庫欠缺系統性建立資料間關聯的問題，本研究提出利用品質機能展開的觀念於建立資料的關聯性。利用品質機能展開的部署策略及其一系列具有邏輯性的展開系統，幫助資料庫系統中階層關係的建立，同時產生資料間的關聯性，並透過關聯式資料庫建立資料關聯的完整性。最後以建構磨床材料清單資料庫為例，說明如何利用本研究所提出的方法，建立磨床材料清單資料庫，表達材料清單各層級零件的組成關係、材料的資訊以及材料間的關係。
本研究的結果有三項：第一，利用品質機能展開具有邏輯性的展開特性，有系統地建立資料庫系統中的階層關係，利於處理眾多關係複雜的物件，幫助資料庫設計者能夠有系統地產生物件關聯。第二，
利用品質機能展開的關念於建構關聯式資料庫之初步規劃後，透過關聯式資料模式與正規化步驟，建立資料間其它可能的關聯，並且消除資料庫中各種可能的異常現象，以建立資料關聯的完整性。第三，利用本研究所提出的方法，建立磨床材料清單資料庫，有效率地建構材料清單樹狀結構中各層級零件的組成關係，並且整合材料的相關資訊以及材料間的關係。When establishing data relationships in a relational database, the database is limited in its data modeling capability and it is also incapable of recording complicated data structures. In order to describe complicated relationships between objects, the database requires another table to accomplish the task. As the data volume increases, the number of table entries increases as well in order to meet this demand. Furthermore, the database lacks a systematic method for describing the relationship between objects. Often times, the results would vary depending on the database designer’s level of experience, expertise, and the method of data entry.
In order to address the lack of a systematic method in relational databases for establishing data relationships, this study applied quality function deployment concept to establish data relationships. The logical expanding strategy system from quality function deployment was applied to help the database to establish relationships in the middle levels, and also to make connections between the data. Furthermore, the relational database was used for the completeness of the database. Finally, the grinder bill of material was used as an example to illustrate how to apply the method developed in this study to establish its database. This expressed the component relationships in each level, the information about the materials, and the relationships between materials.
There are three results in this study: the first is the application of quality function deployment, which has the characteristic of logical expanding, and which was used to systematically develop the relationships for the middle levels in the database. It is especially useful when applied to complicated objects which have many processes. It also helps the database designer to systematically create relationships for the objects.
Second, after applying quality function deployment concept to the construction of a relational database, the process of normal form of relational database is implemented in order to develop possible relationships between the data and it also helps to eliminate any possibility of unusual phenomena in the database, which facilitates the development of a complete database.
Third, the method was applied in this study to construct a database for grinder bill of material. It efficiently formed the relationships for the components in each middle level of the tree structure of the bill of material, and also integrated the information about the materials and the relationships between materials
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
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

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.
