No full text高雄縣土壤調查、於民國三十八年十二月開始，野外觀察採樣，測繪，以至室內化驗，研究，製圖，均經進行完竣，茲將報告書內容摘述於下：
一、地位面積及人口：本縣位於本島之東南部，在東經120˚10’32”-121˚57’12”，北緯22˚28’28”-23˚28’4”，面積2,832.5175平方公里，約合全省面積8.19%，1950年人口為447,296人。
二、河流：本縣河流有下淡水河，阿公店溪，二層行溪及數小溪流，下淡水河自東北向西南流，流長158.6公里。
三、市區：本縣境內有高雄市直屬省府，縣內轄26個鄉鎮。
四、交通：境內除縱貫線鐵路與公路外，尚有各糖廠鐵道與鄉鎮公路，縱橫連絡，除山地外，交通稱便。
五、農林業：本縣農業生產，年有進步，據縣府統計，民國39年作物面積有85,247公頃，佔全省作物面積6%，年產稻穀107,163,778公斤，甘藷134,001,783公斤，甘蔗1,085,820,568公斤，綠肥136,143,706公斤，其他如大豆，花生，玉米，香蕉，鳳梨及蔬菜等亦多有產出。
The soil survey of Kaohsiung, Taiwan, was started in Nov. 1949 and finished in may, 1951 by K.W. Leung and C.C. Chen.
Data concerning the soils, topography, as well as general agriculture were surveyed and collected; the soils were classified into series, types and phases, the areas of each type and phase were ascertained. A map showing location and distribution of soils was prepared. Morphology of e.ch type and phase was described with some data of chemical composicion and mechanical analyses. A general discussion on soil fertility, management and conservation of this prefecture was included
(41(2):216-224)Testing and Evaluating of the Performance of Agricultural Pyranometer
No full text此研究之目的在於開發測試適用本省農業環境之日照計，並比較其各項性能。實驗結果顯示利用光二極體為感測元件的日照計其性能可合乎世界氣象組織之一級標準。利用Cds原理開發之感測器其誤差值偏高，其性能受到使用時期老化之影響。利用國產照度計改良而成之日照計其量測準確度約為20W／m2，持久性能十分穩定且成本低廉，此設備可適用於本省設施日照能量量測與控制作業。
The objectives of this research were to develop and test the performance of serveral pyranometers used in agricultural environment. The experimental results indicated that the accuracy of the Silicon Photovotatic cell pyranometers could compare well with the WMO standards for the first class instruments. The Cds-type solar meter has the higher error and serious aging problem. The accuracy of the INS-series meters that developed from the domestic LUX meter was nearly 20w/m2. The long-term stability was very well and the cost was inexpensive. It could serve as adequate pyranomenter to measure the solar energy and control the shading device for the protected culture in Taiwan
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
