Vibration of ship structures and its control
No full textNoise and vibration in complex ship structures are becoming a prominent issue for ship building industry and ship companies due to the constant demand of building faster ships of lighter weight, and the stringent noise and libration regulation of the industry. In order to retain the full benefit of building faster ships without compromising too much on ride comfort and safety, noise and vibration control needs to be implemented. Due to the complexity of ship structures, the coupling of different wave types and multiple wave propagation paths, active control of global hull modes is difficult to implement and\ud
very expensive. Traditional passive control such as adding damping materials is only effective in the high frequency range. However, most severe damage to ship structures is caused by large structural deformation of hull structures and high dynamic stress concentration at low frequencies. The most discomfort and fatigue of passengers and the crew onboard ships is also due to the low frequency noise\ud
and vibration. Innovative approaches are therefore, required to attenuate the noise and vibration at low frequencies.\ud

This book was developed from several specialized research topics on vibration and vibration control of ship structures, mostly from the author's own PhD work at the University of Western Australia. The book aims to provide a better understanding of vibration characteristics of ribbed plate structures, plate/plate coupled structures and the mechanism governing wave propagation and attenuation in\ud
periodic and irregular ribbed structures as well as in complex ship structures. The book is designed to be a reference book for ship builders, vibro-acoustic engineers and researchers. The author also hopes that the book can stimulate more exciting future work in this area of research. It is the author's humble desire that the book can be some use for those who purchase it. \ud

This book is divided into eight chapters. Each chapter focuses on providing solution to address a particular issue on vibration problems of ship structures. A brief summary of each chapter is given in the general introduction. All chapters are inter-dependent to each other to form an integration volume on the subject of vibration and vibration control of ship structures and alike.\ud

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
地方之愛的生成與危殆：花蓮林田山社區居民的地方感轉變;The Ebb and Flow of Topophilia:A Study of the Change of the Residents’ Sense of Place of Lin-Tian-Shan Community, Hualien
No full text[[abstract]]本研究以人文主義地理學關懷地方的角度出發，試圖了解曾經做為林業社區的花蓮林田山，在1996年邁向園區觀光化和社區人口老化的情況下，居民們地方感的轉變過程，並希望藉由段義孚所謂的地方之愛（Topophilia），說明居民是如何看待林田山過去20年來的變化。透過田野的觀察與訪談，本研究發現，因為林業經濟而形成的林田山社區，居民們等同圍繞著林業時期的運材交通工具「鐵道與索道」而生活著，也建構了居民們將林田山視為家的想像。而自小在林田山成長的居民，成年後選擇留在林田山成家立業，也是基於兒時情誼和對林田山的熟悉。現今的林田山社區，從起初的林業移民，至後來的既有血脈的延續，共同營造了視地方為家園的想像。林田山社區在轉型為林業文化園區後，即便作為觀光化社區的地景和林業時期的住居與工作型態大不相同，居民仍希望藉由地方團體重新取得社區的主導性，並開始納入外來人士的聲音；而邁向園區化若能提供經濟的誘因，居民也從起初的反抗，逐漸轉為接受的態度，但在既有公有宿舍法未解套的情況下，未來公部門的決策仍是左右林田山社區發展的關鍵。
Based upon the perspective of humanistic geography, the study explores how the residents of Lin-Tian-Shan Forestry Cultural Park, Hualien, change their sense of place when facing with the issues of tourism and seniorization. Referring to Yi-fu Tuan’s conceptualization of “Topophilia,” this research illustrates how the landscape change of Lin-Tian-Shan Forestry Cultural Park in the past twenty years affected the way the residents identify with their community. Through field research and in-depth interview, the study found that the residents identiy Lin-Tian-Shan Community as their home mainly due to the old-time forestry industry and their main tools of transportation – railway and ropeway. The residents who grew up there chose to stay due to a strong emotional attachment with Lin-Tian-Shan. Thus, from the immigration of forestry in old days to the long-stay residents in Lin-Tian-Shan community now, the residents consider here as their “homeland.” Following the transformation of Lin-Tian-Shan from a residential community to a heretige site, drastic changes in both living and working follow suit. Nevertheless, the residents still hope that the local community can retake the initiative in regards to the community development, although they are willing to take advices from the outsiders. If transforming into Lin-Tian-Shan Forestry Cultural Park could provide enough economic incentives for residents, they are willing to settle for the new ideas for community development. However, before their dormitory issue is resolved, the government still dominates the future development of Lin-Tian-Shan community
