Multiple shoot induction and rooting of Paeonia lactiflora ‘Da Fu Gui’
Get PDFUnderground buds of herbaceous peony (Paeonia lactiflora Pall.) ‘Da Fu Gui’ were micropropagated in vitro. The basic processes including culture initiation, shoot induction, axillary shoot proliferation and rooting were established. The best initial medium of ‘Da Fu Gui’ was half-strength MS (Murashige and Skoog) medium (double-strength Ca2+) supplemented with 0.5 mg l-1 6-benzylaminopurine (BA) plus 0.5 mg l-1 gibberellic acid (GA3). The best medium for axillary shoot induction was half-strength MS medium (double-strength Ca2+) supplemented with 1.0 mg l-1 BA plus 0.5 mg l-1 kinetin (Kin), while 0.5 mg l-1 BA + 0.3 mg l-1 Kin was best for shoot proliferation. Shoot height at the time of inoculation had a great effect on proliferation and growth of ‘Da Fu Gui’. Putrescine (Put) (0.5 to 5.0 mg l-1) prevented rooting of ‘Da Fu Gui’ but it favored the development of roots. Highest rooting percentage was observed on half-strength MS medium (double-strength Ca2+) supplemented with 1 mg l-1 indole-3-butyric acid (IBA).Key words: Herbaceous peony, underground buds, axillary shoots, micropropagation
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
Community Resilience: The Case Study of Fu-Gui Village
No full text[[abstract]]本研究以福龜村為例探討九二一地震後社區復原的歷程與經驗，以學者Norris等人提出之「網絡型適應能力的社區復原力組合」為理論架構，分析在經濟發展、社會資本、社區能力、資訊與溝通等四個面向之復原情況。爾後，歸納出增強或阻礙復原力之因素，並作為提供未來相關研究或政策之參考基礎。
本研究以質性訪談與田野觀察等研究方法進行資料蒐集，並輔以其他次級資料進行分析，研究結果如下：
一、福龜村於緊急救援階段，當外界資源尚未進入社區時，居民以自救方式因應災情，展現出自立與自助的精神。災難發生數天之後，外界救援方進入社區，該村也積極依社區需求對外尋求與連結資源。
二、在重建與復原階段，村里系統的功能、社區居民的參與和行動、社會網絡與社會支持，以及在地組織連結資源的能力，均影響社區的復原力。其中，「信任」成為過程中重要的因素，其影響社會網絡之間的互動和社區工作的發展。
三、災前社區的脆弱性、資源分配不均、居民對政府和專業團隊因訊息和溝通不足導致不信任的情形，以及政治與選舉的派系衝突，均會削弱社區的復原力。
四、「社團法人南投縣生活重建協會」為九二一地震後發展的重要在地組織，係由在地居民自行連結內部與外部資源設立而成，以解決社區的問題和需求。透過長期在地的經營，逐漸發展出整合型的服務方式，提供社區居民照顧服務與滿足福利服務的需求。這些服務也提供了婦女就業和學習機會，進而增加她們的經濟收入。而九二一地震發生17年後的福龜村，面臨著人口老化和人口外移等問題，此為社區和組織當前關注的議題。
本研究建議：災後長期重建應關注社區內高脆弱性的人口群，並透過具創造力與彈性的方式解決社區內的需求和問題。除了持續關注偏鄉人口外移或人力資源缺乏的議題之外，更須著重平時在社區中建立資源和社會網絡之連結，促進在地組織之間的密切合作以備不時之需。針對社會工作者而言，需要對在地組織、長期重建和災後社區發展等議題有持續性地關注。[[abstract]]This study uses Fu-gui Village as an example to explore the process and experience of community resilience after 921 earthquake. Theoretical framework is based on “community resilience portfolio of network adaptation capacity” proposed by Norris et al. It analyzes resilience of economic development, social capital, community capacity and information and communication. Subsequently, it generalizes the factors which reinforce or hinder resilience and serves as reference for future related research or policy.
This study collects data by qualitative interview and field study and conducts analysis by other secondary data. Research findings are shown below:
1.In Fu-gui Village, at the phase of emergency, before external resources accessed the community, the residents responded to the disaster by self-rescue and demonstrated the spirit of independence and self-help. Several days after the disaster, external relief approached the community and the village actively searched for and connected with external resources according to community demand.
2.At the phase of reconstruction and resilience, function of neighborhood system, participation and action of community residents, social network and social support and capacity of local organizations to connect the resources all influenced community resilience. Among others, “trust” becomes the key factor in the process and it influences the interaction in social network and community work development.
3.Community vulnerability before the disaster, unequal resource distribution, residents’ mistrust in government and professional team due to lack of information and communication and political and electoral faction conflict all lowered community resilience.
4.“Life Reconstruction Association of Nantou County” is the important local organization developed after 921 earthquake and it was founded by local residents who connect internal and external resources in order to solve community problems and needs. With long-term local operation, it successively develops integrated service to provide care service to community residents and satisfy their needs of well-being. The services offer jobs and learning opportunities for women and increase their incomes. Fu-gui Village, 17 years after 921 earthquake, encounters the problems of population aging and immigration. It is the current issue concerned by the community and organization.
Suggestions of this study: long-term reconstruction after disaster should be based on the concern for highly fragile population in the community. It should solve community needs and problems by creative and flexible measures. Besides continuous concern about the issues of population immigration or lack of human resources, it should pay attention to resource construction and social network in the community and reinforce cooperation among local organizations. For social workers, they should persistently follow the issues such as local organizations, long-term reconstruction and community development after disaster.[[note]]碩
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
