    對阿里山國有林班地種植山葵的意見調查與分析

    No full text
    民國七十二年阿里山山公路通車後,因交通方便,人口急速回流,加上外來人口湧入,種植山葵的成本降低,加上日本商人之收購,種植百姓越來越多,但在林地內種植山葵會對水土環境造成衝擊,由於山葵問題的處理牽涉到當地百姓的生計與國土保安政策衝突的瓶頸,本研究為瞭解一般民眾對山葵問題的看法,訪問了901位民眾,有效問卷為895份,其中有697的民眾(佔77.9%)認為處理阿里山山葵最適合的方法是「設置山葵專業區」。只是要設置專業區,尚需有關單位做進一步的研究。Owing to high commercial value, suitable geographical site and well developed traffic network, planting area of Wasabi is increasing rapidly in Alishan’s national forest land. But plantation of Wasabi has caused environmental impact in Alishan area. The

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    混農林業永續發展的初探

    No full text
    審視混農林業的特性與永續發展的目標,發覺兩者間有許多類似之處,例如混農林業系統的特性包括: 競爭性、複雜性、獲利性與永續性;永續發展的目標包括經濟目標、生態目標與社會目標;混農林業的競爭性、複雜性與永續性符合永續發展的生態目標,而混農林業的獲利性則符合永續發展的經濟與社會目標;臺灣地區混農林業永續發展的各項目標中,林農對生態與水土保持方面略具信心,因為林農認為在混農林業中,林木具有「保育水土」、「維持土地肥力」的功能;但是林農對混農林業的中農作物的收益與銷售管道的分數均在普通以下。而對林產品的經濟收入與銷售管道的績效都在「不好以下」方面普遍較沒有信心,尤其在林產品方面的信心方面更是低落。因此如何提振林農對混農林業的信心,以落實混農林業的永續經營,是未來必須研究的課題

    阿里山森林遊樂區之遊憩效益:以條件評估法與旅遊成本法評估為例

    No full text
    遊憩效益的評估,通常是推動許多遊憩事業公共投資或環境品質改善計劃所應考慮的問題。而遊憩效益是屬於環境財貨之一種,它並沒有市場價格,無法直接使用傳統的需求理論來衡量品質改變所造成的效益或成本,因此就有效益衡量的理論及非市場財貨評估法(non-market valuation techniques)的產生。因此本研究將使用經濟效益衡量中的旅遊成本法與條件評估法來衡量享譽國際的阿里山森林遊樂區的經濟效益。 本研究經過一年的訪問共收集有效問卷為392份。而對於阿里山森林遊樂區之遊憩效益,本研究結果所推估所得到的The+estimation+of+recreation+benefit+was+always+adopted+by+public+investment+in+recreation+activities+or+the+plans+of+improving+environmental+qualities.+Recreation+benefit+belongs+to+one+of+environmental+goods+and+always+gets+non-market+price.+When+tota

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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

    The main purposes of this study are to comprehend leased land of national forest's current agroforestry's situation, factors which influence agroforesters' decision making in agroforesty management and evaluation of agroforestry's tech本研究的主要目的在瞭解現階段臺灣地區國有林班租地造林實施混農林作業現況、探討影響混農林主經營混農林作業決策的因素與對混農林作業體系進行評估。本研究訪問了全省八個林管處的400戶混農林戶,贊成實施混農林業的百分比佔71.5%,主要誘因是農作物有收入、林木保育水土、維持土地肥力。而對混農林業的總體評估的結果顯示:1. 對農作物的收益與銷售管道抱持著悲觀的看法。2. 對混農林業在保育水土、美化環境與農林作物的生長抱持著審慎樂觀的看法。3. 林產品收益與銷售管道抱持著很悲觀的看法。4. 混農林業對社區產業的發展
