IF ONE THING CAN BE RESOLVED WITH BIAOQING BAO, THEN DON'T USE WORDS!”: THE GENEALOGY OF BIAOQING BAO IN THE CHINESE INTERNET CULTURE
No full textAs one of the trendiest Internet memes in China, Biaoqing Bao has experienced fast development, from the early emoticons used on QQ and Internet images inspired by the rage comics in the late 2000s to a brand new branch of online communication tool around 2015. Biaoqing Bao has its distinctive feature to combine images and texts together to convey users’ emotions and feelings. Various technologies like Biaoqing Bao generators also enable users to draw different sorts of materials, such as social hot issues, to make them into Biaoqing Bao. Biaoqing Bao thus offers a vantage point to look at today’s Chinese pop culture. In this thesis, I will investigate the origin of Biaoqing Bao which can be traced back to 2009 when a new type of images emerged online to vent netizens’ sentiment against the Internet censorship launched by the Chinese government. As the predecessor of Biaoqing Bao, these images served the subversive purpose against the authoritarian manipulation over the cyber space. Although the subversive spirit embodied in Biaoqing Bao seems to subside when Biaoqing Bao has been more and more used on major instant messaging platforms, the creativity in Biaoqing Bao still leaves relatively free space for netizens to fully represent their digital selves and celebrate such liberty of expression. I will also investigate the 2016 Facebook campaign launched by the Chinese mainlanders, to demonstrate that such a subversive symbol plays an important role in constructing a united national identity to participate in the international political dispute. Biaoqing Bao provides a channel to vent the netizens’ anger in a playful way, in contrast to the moderate attitude of the government. In this sense, I argue that Biaoqing Bao, as one of the semiotic codes created and circulated on the Internet, is not only a visual entertainment in communication as a signifier of Chinese pop culture, but also a practice that represents a subversive symbol that strives against any forms of authoritative regulation and manipulation in the Chinese Internet culture

Fibras de vidro a base de Li20 - Zr02 - BaO - Si02 recobertas com Nb205 para utilização em micro-extração em fase sólida
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências Físicas e Matemáticas. Programa de Pós-graduação em QuímicaNeste trabalho são descritas as metodologias para obtenção e modificações da superfície de fibras de vidro de composição Li2O-ZrO2-BaO-SiO2. Apresenta-se também as aplicações destas fibras na determinação, por SPME, de fenol e de uma mistura de álcoois. Para obtenção das fibras de vidro construiu-se um equipamento, o qual baseia-se na técnica de estiramento. As fibras de vidro foram recobertas utilizando-se duas técnicas: Decomposição de Organometálicos, onde o etóxido de nióbio (V) foi empregado como reagente precursor do óxido de nióbio (V), e Deposição de Vapor Químico, na qual fez-se uso do cloreto de nióbio como precursor do óxido de nióbio (V).Utilizou-se da técnica de Microscopia Eletrônica de Varredura para avaliar a morfologia das fibras sem recobrimento e recobertas. O recobrimento com óxido de nióbio sobre a superfície das fibras foi estudado pela técnica de "Color Map" e as análises químicas realizadas pela Microssonda de Energia Dispersiva, ambas as técnica acopladas ao MEV. A Técnica de Micro-extração em Fase Sólida foi utilizada para avaliar a capacidade de adsorsão de compostos polares e apolares pelas fibras recobertas. Com os resultados obtidos, verficou-se que pela técnica de CVD obtem-se fibras com um recobrimento mais homogêneo e espesso. Estas fibras apresentaram melhor eficiência no processo de adsorção como verificado pelos resultados cromatográficos
DIETARY CONDITIONS AND DIFFERENTIAL ACCESS TO FOOD RESOURCES AMONG THE VARIOUS CLASSES DURING THE HAN PERIOD
No full textIn this thesis, I study how food resources and dietary conditions were determined by social and economic status during the Han period in China, B.C. 206~A.D.220. Even though earlier scholars have published research concerning the Chinese food culture of this period, these studies were limited in that they only illustrated the dietary culture of the upper class or the available food resources in one geographic area. Also, without any persuasive data, it has been assumed by these earlier scholars that there were big differences in food resources and food consumption between the upper and lower classes. In this thesis, for comparison among the classes, I divide the social and economic classes into five stratified groups: nobles, officials, peasants, soldiers and convicts. After a brief introduction of the nature of each social class, I examine the food resources and nutritional condition of each group using information such as the wealth and income of each group, the market price of food resources, the agricultural products of peasants, and the amount of food distribution to soldiers and convicts. I found these data from archaeological remains, received historical records and pictorial data, and excavated texts. This research shows a broader view of Chinese dietary condition focusing not only on the variety of food resources of nobles, but also on the different food accessibilities among the officials, and the food deficiencies of peasants. It also deals with the situations of food supply for soldiers and convicts in an effort to reveal the true dietary consumption and nutritional conditions for all Chinese. This research proves that the various classes during the Han period in China had different food resources and dietary conditions
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Emergent Capabilities for Collaborative Teams in the Evolving Web Environment
No full textThis paper reports on our investigation of the latest advances for the Social Web, Web 2.0 and the Linked Data Web. These advances are discussed in terms of the latest capabilities that are available (or being made available) on the Web at the time of writing this paper. Such capabilities can be of significant benefit to teams, especially those comprised of multinational, geographically-dispersed team members. The specific context of coalition members in a rapidly formed diverse military context such as disaster relief or humanitarian aid is considered, where close working between non-government organisations and non-military teams will help to achieve results as quickly and efficiently as possible. The heterogeneity one finds in such teams, coupled with a lack of dedicated private network infrastructure, poses a number of challenges for collaboration, and the current paper represents an attempt to assess whether nascent Web-based capabilities can support such teams in terms of both their collaborative activities and their access to (and sharing of) information resources
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
BAO signatures in the 2-point angular correlations and the Hubble tension
No full textAn observational tension on estimates of the Hubble parameter, , using early and late Universe information, is being of intense discussion in the literature. Additionally, it is of great importance to measure independently of CMB data and local distance ladder method. In this sense, we analyze 15 measurements of the transversal BAO scale, , obtained in a weakly model-dependent approach, in combination with other data sets obtained in a model-independent way, namely, Big Bang Nucleosynthesis (BBN) information, 6 gravitationally lensed quasars with measured time delays by the H0LiCOW team, and measures of cosmic chronometers (CC). We find km s Mpc and km s Mpc from +BBN+H0LiCOW and +BBN+CC, respectively, in fully accordance with local measurements. Moreover, we estimate the sound horizon at drag epoch, , independent of CMB data, and find Mpc (from +BBN+H0LiCOW) and Mpc (from +BBN+CC). In a second round of analysis, we test how the presence of a possible spatial curvature, , can influence the main results. We compare our constraints on and with other reported values. Our results show that it is possible to use a robust compilation of transversal BAO data, , jointly with other model-independent measurements, in such a way that the tension on the Hubble parameter can be alleviated
