Anti-Structure and Decompose:The Multiple Genders of Queer Tango in Buenos Aires
布宜諾市19世紀末所孕生的探戈舞蹈,是現代阿根廷文化的源頭之一,了解探戈的演進過程,得以窺見阿根廷近代政治歷史的發展。阿根廷在1983年過後,進入民主憲政時期,為當代的同志運動奠下了發展的基礎。在眾多社運團體於1990年代後蓬勃發展的同時,對探戈有興趣的性少數者也逐漸從隱匿的朋友舞會往公開的米隆加場域發展,在21世紀初形成「酷兒探戈」的前身─「同志米隆加」。
酷兒探戈與傳統探戈最大的不同是,它鼓勵在舞蹈之中自由對調帶領者和跟隨者的角色。本研究受到巴特勒的「性別操演」概念所啟發,藉由布宜諾市酷兒探戈場域和慶典的儀式過程性質,探討個體的性慾別特質如何在結構與反結構之間轉化、流動和重構。研究發現,酷兒探戈匯聚了大量的「反結構」特性,因此集結了一股對主流社會結構的「解構」力量。在反對父權與異性戀霸權之基礎上,酷兒們以一種較為柔和的方式─探戈舞蹈─深入人心,在扭轉傳統探戈僵固的二元結構過程中,逐步滲入一種較為平等的意識形態,並且為探戈舞蹈注入多元性別實踐的可能性。
酷兒探戈所發明的「角色對調」(role-exchange)舞步,彷彿是對20世紀初布宜諾市港口小混混(compadritos)在特殊時空背景下形成的男男同性探戈(práctica)之致敬,但是事實上更接近是一種反動的歷史結果。酷兒探戈不僅開闢了一個讓LGBTQ者可以跳探戈的場域;而且,它也為傳統探戈開闢了新的可能性,讓傳統兩性親身感受和理解兩種角色的性別操演特性,返還回來增加傳統探戈舞者彼此之間溝通的敏感度。Tango Dancing, as an important part of cultural elements in Argentina, is originated from Buenos Aires at the end of 19 century. Surveying the history of tango dancing, we could get the picture of modern political and historical development at Argentina. In 1983, after the military dictatorship had collapsed and democratic elections were held, the expectations of lesbian and gay movement had grown. In 1990s, at the same time when many activists and communities flourished, LGBTQ who were interested in tango gradually had their milonga from private meeting to public sphere, which was the forerunner of queer tango, called “gay milonga”.
The most important difference from queer tango and traditional tango is that we could change roles between leader and follower freely when dancing tango. This thesis considers the queer tango and festival of Buenos Aires as the ritual process, inspired by the theory of gender performativity from Butler, and discusses how gender and sexuality are transformed, floated and reformulated between the structure and anti-structure. The author finds out, the agency from the anti-structure of queer tango could decompose the social structure.
Otherwise, against the patriarchy and heterosexual hegemony, differing from the fixed binary opposition in traditional tango, queer tango offers a kind of dance which is more equal and allows tanguero/a to discover more possibilities of multiple gender practices in tango dancing. Queer tango not only offers LGBTQ milonga for tango dancing, but also allows men-women to realize the gender performativity from being leader or follower, which could improve the sensibility between traditional tango dancers
Total Synthesis of Man9GlcNAc2 Glycan as Anti HIV Vaccine Candidate
HIV 是造成AIDS(後天免疫缺乏症候群)的主要原因,而世界各地的學者亦紛紛
投入相關的研究。而在HIV 病毒的套膜上,發現了醣蛋白,gp120。此醣蛋白對
於HIV 病毒進入宿主細胞的過程中,扮演著重要的角色。而研究發現,2G12 抗
體可辨認gp120 上的Manα(1-2)Man 的甘露寡醣基團。藉此訊息,期望可設計出
具有免疫原功能的甘露寡醣基團,而達到中和HIV 病毒的功用。
在醣類合成的領域上,針對於複合醣類的合成已發展出多套系統。例如本實
驗室最常使用之程式化一鍋法(programmable one-pot)。藉由RRV 值的分析以及
陳駿儀學長論文之佐證下,欲採用程式化一鍋法合成甘露寡醣基團是相對困難
的。因此於合成設計上,本論文採用逐步(step by step)的合成策略。
而本論文中,藉由嘗試著改善甘露寡醣的合成路徑,成功地克服了甘露糖的
低結晶性質,以及合成過程中所遭遇的一些問題,利用逐步合成的策略獲得甘露
寡醣的構築體。並且期望能藉由此類構築體,設計出效果佳的醣類免疫原,並有
效的中和HIV 病毒。HIV-1 (Human Immunodeficiency Virus Type 1) is the causative agent of AIDS.
The HIV-1 envelope is a basic lipid bilayer that contains the gp120 and gp41
glycoprotein. The antibody 2G12 could broadly neutralize HIV by binding to gp120,
and it was able to recognize Manα(1-2)Man structure. Man9GlcNAc2, the high
mannose-type oligosaccharide, is found expressed excessively on gp120. Based on
this information, we should synthesize the high mannose-type oligosaccharide antigen
for anti HIV-1.
Carbohydrates are universal and play an important roles in biological system. For
example, the programmable one-pot carbohydrates synthesis has been developed by
Dr. Wong. However, based on the previous studies, it is difficult to synthesize
high-mannose oligosaccharide via this protocol.
In this thesis, I redesigned some building blocks for Man9GlcNAc2 synthesis We
started from commercially D-mannose and designed the alternative strategies to
overcome synthetic problem and provided the building blocks in high purity and yield.
By using these building blocks, we hope the high-mannose oligosaccharide can be
synthesized and high protective vaccine can be developed in the near future
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
Fabrication and analysis of 4H-SiC MOS Capacitor with High-k Gate Dielectrics:ZrO2,Y2O3
本論文製作兩種金氧半電容元件,基板使用4H-SiC,氧化層使用ZrO2和Y2O3為閘極氧化層,等效於SiO2厚度為10nm,閘極使用鋁閘極,我們使用四種不同的溫度條件,基板在常溫下和基板加熱200℃及沒有退火和快速熱退火溫度500℃的組合。可以得到四種溫度環境。基板室溫加不退火;基板不加熱加退火溫度500℃;基板加熱200℃加不退火,基板加熱200℃加退火溫度500℃。
可以得到漏電流關係在Y2O3基板不加熱、不退火,電場強度為1MV/cm是10-1A/cm2,在基板加熱200℃、不退火,電場強度為1MV/cm時,漏電流為10-3A/cm2,基板不加熱、快速熱退火溫度500℃或加熱基板200℃、快速熱退火溫度500℃,電場強度為1MV/cm時,漏電流密度都是10-6A/cm2。ZrO2基板不加熱、沒有退火,電場強度為1MV/cm時,漏電流密度是10-1A/cm2,在基板加熱200℃、不退火,電場強度為1MV/cm時,漏電流密度為10-3A/cm2,基板不加熱或基板加熱200℃、快速熱退火溫度皆為500℃,電場強度為1MV/cm時,漏電流密度都是10-7A/cm2,至於C-V量測方面,在兩種薄膜的電容情況,平帶電壓有的偏移現象,可能是濺鍍造成過多的氧化層電荷在氧化層中堆積,形成偏移,但經由快速熱退火製程有達到減少氧化層電荷的作用。In this research, we design two kinds of MOS-Capacitors with ZrO2 and Y2O3 as the insulators. (Equivalent Oxide Thickness, EOT) EOT is 10nm.Therefore, ZrO2 and Y2O3 were deposited on substrates at different substrate temperature (room temperature and 200℃) and then (Rapid Thermal annealing, RTA) at 500℃.We can get four kinds of temperature conditions. Condition1:Tsubtrate is room temperature, and Tannealing is room temperature. Condition2:Tsubtrate is room temperature, and Tannealing is 500℃.Condition3:Tsubtrate is 200℃. and Tannealing is room temperature.Condition4:Tsubtrate is 200℃,and Tannealing is 500℃.
We report the C-V, I-V electrical measurement results of MOS capacitors using Y2O3 thin film deposited by RF sputtering. The leakage current density is about 10-3A/cm2 at 0.5MV/cm in condition 1.The leakage current density is about 10-3A/cm2 at 1MV/cm in condition 2.The leakage current density is about 10-3A/cm2 at 1.5MV/cm in condition 3.The leakage current density is about 10-3A/cm2 at 1.6MV/cm in condition 4.ZrO2 thin film deposited by RF sputtering. The leakage current density is about 10-3A/cm2 at 0.5MV/cm in condition 1. The leakage current density is about 10-3A/cm2 at 1MV/cm in condition 2. The leakage current density is about 10-3A/cm2 at 0.8MV/cm in condition 3. The leakage current density at 1MV/cm is about 10-3A/cm2 at 2.7MV/cm in condition 3, and condition 4.
According to the results, the ZrO2 thin film is better than Y2O3 for the leakage current. the C-V measurement result of MOS capacitors using Y2O3 and MOS capacitors using ZrO2,the flat band voltage is shift. The possible reason is more fixed oxide charge and mobile ion charge in oxide layer. We have reduced charge in oxide layer by RTA process
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
Dispelling the Myths Behind First-author Citation Counts
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
