Theoretical and Textual Approaches to Contemporary Humanitarian Narrative: The Cases of Roberto Saviano’s Gomorra, Aung San Suu Kyi’s Letters from Burma, Jerry Piasecki’s Marie in the Shadow of the Lion and Nadine Gordimer’s The Ultimate Safari
No full textThe purpose of this thesis is to describe how some forms of fictional and non-fictional texts can be configured as and within the framework of humanitarian practices. In exploring the definitions and features of humanitarianism and humanitarian literature, the thesis attempts to answer the question of what purpose these texts try to serve. In examining the works Marie in the Shadow of the Lion (2000) by Jerry Piasecki, The Ultimate Safari (1989) by Nadine Gordimer, Gomorra (2006) by Roberto Saviano and Letters from Burma (1996) by Aung San Suu Kyi, we will argue that the scope of these books can be located by analogy to social and political humanitarian practices. Beyond their differences in genre, style and subject matter, these texts share a common feature: they are performative, namely they strive to do things with words. The humanitarian texts discussed in this thesis can be shown to act in the world in order to implement the values proclaimed in the Universal Declaration of Human Rights

Effect of impression technique and material on accuracy of implant impressions
No full textDental implant treatment becomes one of the most predictable and successful dental rehabilitation therapies. After successful osseointegration, impression making is one of the most important and critical steps in implant prothesis fabrication for long term successful use. An accurate impression and stone casts are extremely important because inaccuracy in any of these can lead to mechanical and /or biological complications which ultimately result in failure of implant restoration.
An in vitro study was carried out to evaluate linear dimensional accuracy of implant impressions by using different silicone impression materials and different impression techniques.
Four implants (Arrow Mytis Implant System, Brainbase Co. Ltd., Tokyo, Japan) were parallelly placed in the edentulous mandible model using the surgical guide at canines and first molar areas. Fixture-level impressions were made by using addition silicone (Perfit, Huge, Rizhao, China) or condensation silicone (Silect Set, Muller-Omicron GmbH&Co.KG, Germany) with putty-light body wash one-step procedure, with closed tray or open tray technique and poured with dental stone (Silky Rock, Type IV stone, U.S.A). Three hours after removal of impression from the stone cast, four measurements (AB, BC, CD, AD) were taken between implants by using digital slide caliper (Hummer, Thailand) with accuracy of +0.03mm. Data was analyzed by using one-way ANOVA.
There was no statistically significant difference in deviation of linear dimension between the impression materials and techniques. It is concluded that both addition and condensation silicones may ensure acceptable accuracy with either closed tray or open tray technique for implant impressions.HOW TO CITE: San SP, Win TN, Aung T, Lin AZ, Aung S, Aung KH, Nyan M, Tint K.

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
