Out of Absurdity On the Ending of Catch-22

As one of the first and most original creations of literary postmodernism, published in the year 1961, Catch-22＇s （1961） position in American literature remains secure. Yet its ending has been held as unconvincing ever since its publication. Taking the overall structure, tone, and the theme of the novel into consideration, this paper aims to prove the credibility of this controversial part. It consists of five sections apart from an introduction and a conclusion. Section One provides general information on the life and works of Joseph Heller. Section Two traces the impact of existentialism and the generation of black humor to clarify the literary position of Catch-22. Section Three brings out the disputative opinions on the ending part. Sections Four and Five, try to prove Yossarian＇s final desertion a natural and convincing ending from different perspectives： Section Four analyses how Yossarian gains an entropic vision of the cosmos; section Five studies his existential vision of physical life and searches for the immediate factors that propel Yossarian＇s desertion. Section five also explains the ending＇s change in tone and structure. The conclusion summarizes the paper and points out the social significance of the novel.

Based on the tortuous-expanding path/channel model,a micro-mechanism model for porous media is developed.The proposed model is expressed as a function of tortuosity,porosity,resistance coefficient,and fluid properties.Every parameter in the proposed model has clear physical meaning.The results show that the model predictions are ingood agreement with those from the existing experimental data.

The Effect of Class and Employment Type on the Awareness of Irregular Work Issues in Korea and ｜apan

Recently, there is greater recognition and increased attempts to protect the rights of irregular workers within Korea and Japan, especially in Korea. This is because of more and more public awareness of the polarization in material conditions between regular workers and irregular workers. So, this study focuses on the main factors explaining awareness of irregular worker issues of each of the classes, and relationship between class consciousness in both countries. The result shows that among factors affecting awareness of irregular work issues, negative effect of subjective employment stability was significant in both countries. In regard of anti-flexibility, while strong class effect was observed in Korea, negative effect of anti-neoliberalism was observed in Japan. This is seemingly contradictory that who opposes neoliberal economic policies agrees with labor market flexibilisation. This phenomenon could be explained by labor market characteristics in Korea and Japan. Japanese labor market is characterized by low flexibility and strong segmentation, while Korean labor market is characterized by high flexibility and strong segmentation. Interaction of these two characteristics increases the labor market inequality in Korea.

Understanding protein palmitoylation:Biological significance and enzymology

Protein palmitoylation is a widespread lipid modification in which one or more cysteine thiols on a substrate protein are modified to form a thioester with a palmitoyl group.This lipid modification is readily reversible;a feature of protein palmitoylation that allows for rapid regulation of the function of many cellular proteins.Mutations in palmitoyltransferases(PATs),the enzymes that catalyze the formation of this modification,are associated with a number of neurological diseases and cancer progression.This review summarizes the crucial role of palmitoylation in biological systems,the discovery of the DHHC protein family that catalyzes protein palmitoylation,and the development of methods for investigating the catalytic mechanism of PATs.

Surface mass balance and its climate significance from the coast to Dome A, East Antarctica

Based on stake measurements conducted along the Chinese Antarctic traverse since Jan.1999,we investigated the characteristics of surface mass balance(SMB)and related climate consequences from Zhongshan Station to Dome A,East Antarctica.Spatial analysis suggests that post-depositional processes have a great impact on surface morphology;thus,the representativeness of a single measurement should be discussed in conjunction with local climate features.The comparison among snow accumulation,ice sheet thickness,surface elevation,and ice velocity indicates that the bedrock topography has an indirect connection with the SMB patterns through controlling the surface topography and local climate.The observation reveals that the Lambert Glacier Basin has been experiencing increasing mass input(4.5%),whereas the inland area has experienced a 6%loss,since 2005.An overall estimation of the SMB along the route is 71.3±44.3 kg m?2 a?1,but the annual and regional variation is considerable.Tendency analysis shows that there are four sections with different SMB patterns as a result of three moisture sources and surface climatic discrepancy in the Antarctic inland.This study is the first to identify four SMB patterns from the coast to the Dome area and should provide a valuable contribution to modeling and remote sensing on a continental scale.

A Cellular Automaton Model for Heterogeneous and Incosistent Driver Behavior in Urban Traffic

In this paper a cellular automaton model is proposed to describe driver behavior at a single-lane urban roundabout. Driver behavior has been considered as heterogeneous and inconsistent. Most traffic papers in the literature just discussed heterogeneous driver behavior, to our best knowledge. Two truncated Caussian distributions are used to model heterogeneous and inconsistent driver behavior, respectively. The physical meanings of two truncated distributions are indicated. This method may help enhance a better understanding of driver behavior at roundabout traffic, and even possibly provide references for roundabout design and management.

Mineralogical feature and geological significance of muscovites from the Longyuanba Indosinian and Yanshannian two-mica granites in the eastern Nanling Range

Emplacement P-T condition estimations using granites are important for understanding metamorphic and erosional processes of orogenic belt.Granites are widespread in South China and a majority of them are peraluminous.Particularly,over 91%of the Indosinian granites exposed in the region are peraluminous in composition.It is extremely hard to determine the pressure of intrusion of these peraluminous granites due to the absence of amphibole,a good mineral barometer commonly identified in metaluminous granites.Muscovite is a common mineral in peraluminous granites,certain kind of it could be used as a mineral barometer to constrain the emplacement pressure of peraluminous granites.In this paper,results of petrographic and geochemical studies of muscovites from the Indosinian and early Yanshanian two-mica granites at the Longyuanba in the eastern Nanling Range are reported.Based on petrographic studies,the primary muscovite can be discriminated from the secondary muscovites.Muscovites from the Indosinian two-mica granites are enriched in Ti,Al,Mg,and Na,and depleted in Fe and Mn.Geochemically,these muscovites were considered as primary,whereas those from the Yanshanian two-mica granites fall into the area of secondary muscovite on discrimination diagrams.Barometer estimations show that pressures calculated for primary muscovites are accurate,but those calculated for secondary muscovites are overestimated.The average pressure of emplacement of the Longyuanba Indosinian two-mica granites is 5.9 kbar,corresponding to^19 km in depth,suggesting that the Indosinian granitic magmas were probably generated by partial melting of a thickened crust root in a compressional tectonic setting.

Origin and geological significance of the 1.81 Ga hyalophane-rich pegmatite veins from the high-pressure granulite terrain in the Central Zone of North China Craton

Hyalophane-rich pegmatites are identified from the Manjinggou high-pressure granulite terrain in the Central Zone of North China Craton. Based on field investigation, mineral assemblage and mineral geochemistry, two types of pegmatites can be defined, i.e., hyalophane pegmatite and hyalophane-rich pegmatite. The hyalophane pegmatite is composed of pure hyalophane with 18.7 mol%-19.4 mol% celsian, whereas the hyalophane-rich pegmatite consists of clinopyroxene + titanite + epidote + hyalophane with 11.9 mol%-12.5 mol% celsian. Hyalophane-rich pegmatite has typical magmatic zircons with oscillatory zoning and high Th/U ratios, implying that this type of pegmatite crystallized from special melt similar to magma. SIMS (Cameca 1280) zircon U-Pb dating shows that the crystallization age of the hyalophane-rich pegmatite is 1812±5 Ma, younger than the regional metamorphic age (peak of ca. 1.85 Ga). Zircon δ18O (8.0 ‰-9.3 ‰) and ?Hf (-7.0 to-2.7) values measured by SIMS suggest that the high-pressure granulite terrain was the source of these veins. Therefore, the hyalophane-rich pegmatite veins were likely to be generated by melting of the high-pressure granulite terrain during post collisional uplift. A quick tectonic uplifting process with a velocity of 0.4 to 0.6 mm/a has been estimated for the high-pressure granulite terrane from the Central Zone of North China Craton.
