China’s Politics and Bilateral Trade Linkages
Jianhong Zhang,Arjen van Witteloostuijn,J. Paul Elhorst 서울대학교행정대학원 2011 Asian Journal of Political Science Vol.19 No.1
China’s position in the world economy during the past half-century provides vitalinformation for investigating the relation between politics and trade. Although there is asubstantial number of studies in this area, the current study extends the literature in atleast three ways: (1) it is one of the first studies that investigates the problem of apotential sample selection bias*as a result of the fact that countries taken up in theanalysis are not randomly sampled from all countries in the world; (2) it considers thirdcountryeffects that follow from the fact that China’s relation with any two countries isaffected by the relation between these countries themselves; and (3) it tests the impact offive political arrangements simultaneously, which is more comprehensive than anyformer study. By using data as to 78 of China’s trade partners over the 19502002period, this study provides empirical evidence for the hypotheses that the establishment ofdiplomatic relations, cooperation, visits of heads of states and political system similarityare associated with greater trade flows. The hypothesis that member countries of aPreferential Trading Agreement have had smaller trade flows with China, which is nomember of any of these Preferential Trading Agreements, is not supported by the results.

Objective: The present study aimed to investigate whether the long-lasting, recurrent restricting of sows leads to the physiological and psychological reaction of discomfort. Methods: Sows (Large White) that had experienced restricting for about 0.5 or 3 years and agematched sows kept in a group housing system (loose sows) were compared. Pupillary light reflex parameters were measured at the weaning stage. Immediately after slaughter, blood samples were taken to measure serum cortisol levels, and the brain was dissected, gene expression in the hippo-campus, frontal cortex and hypothalamus was analyzed. Results: The serum cortisol levels were higher in the confined sows than in the loose sows. The full maturity, but not the young adolescent, confined sows had longer latency time in the onset of pupil constriction than their loose counterparts. Real-time polymerase chain reaction analyses revealed an increased expression of interleukin 6 mRNA in the hippocampus and decreased expression of brain derived neurotrophic factor mRNA in hippocampus and hypothalamus and to a lesser extent in the frontal cortex of the full maturity confined sows, compared with the full maturity loose sows. Conclusion: Taken together, these data indicated that recurrent restricting stress in full maturity sows leads to the physiological and psychological reaction of discomfort.

Ni/SBA-15 catalyst was prepared by homogeneous precipitation method (Ni-HP) and used for dry reforming of methane (DRM). The related characterization results indicated that the Ni particles were highly dispersed with a size range of 2-5 nm. Compared with Ni/SBA-15 catalyst prepared by impregnation (Ni-IM), the reduction temperature of Ni-HP obtained from H2-TPR was greatly improved, suggesting the stronger metal-support interaction. After reacting at 700 oC for 100 h, the CH4 conversion of DRM over Ni-HP catalyst slightly decreased from 74.5% to 73.8%. While, for the Ni-IM catalyst, the CH4 conversion dropped from 61.7% to 37.3%. Furthermore, the average particle size of Ni-HP was 3.7 nm and 4.7 nm before and after the long-time stability test, respectively, ascribed to the good antisintering property. Although a certain amount of coke was produced, mainly with disorder filamentous carbon of basegrowth, the Ni/SBA-15 prepared by homogeneous precipitation exhibited excellent catalytic activity and stability.

Objective: Three genome-wide association studies (GWAS) and a meta-analysis of GWAS were conducted to explore the genetic mechanisms underlying variation in pig teat number. Methods: We performed three GWAS and a meta-analysis for teat number on three pig populations, including a White Duroc${\times}$Erhualian $F_2$ resource population (n = 1,743), a Chinese Erhualian pig population (n = 320) and a Chinese Sutai pig population (n = 383). Results: We detected 24 single nucleotide polymorphisms (SNPs) that surpassed the genome-wide significant level on Sus Scrofa chromosomes (SSC) 1, 7, and 12 in the $F_2$ resource population, corresponding to four loci for pig teat number. We highlighted vertnin (VRTN) and lysine demethylase 6B (KDM6B) as two interesting candidate genes at the loci on SSC7 and SSC12. No significant associated SNPs were identified in the meta-analysis of GWAS. Conclusion: The results verified the complex genetic architecture of pig teat number. The causative variants for teat number may be different in the three populations

Huazhong Tu(Huazhong Tu),Yili Zhang(Yili Zhang),Jianhong Wang(Jianhong Wang) 아시아사회과학학회 2022 Jornal of Asia Social Science Vol.9 No.1
The Sikh Empire was a major power in the Indian subcontinent during the 19th century. It was founded by Maharaja Ranjit Singh in 1799 and lasted until its annexation by the British Empire in 1849. The empire was based in the Punjab region, and its capital was the city of Lahore. Maharaja Ranjit Singh unified the various Sikh factions in the region and expanded the empire to include much of the Punjab, as well as parts of present-day Afghanistan, Kashmir. The Sikh Empire was known for its religious tolerance and military prowess, and it was a major regional power in South Asia. The culture of the empire was a mix of Hindu, Muslim, and Sikh traditions. The empire was eventually defeated by the British Raj in the Second Anglo-Sikh War, but its legacy remains to this day. This essay explores the Sikh Empire's ascent from the late 18th century to its fall in the middle of the 19th century. and its lasting impact on the Indian subcontinent. It looks at the rise of the Sikh Empire under the leadership of Maharaja Ranjit Singh, the consolidation of the Sikh Empire, and how its political and military power was used to shape the region. It considers the political influence of the Sikh Empire, its impact on culture, art, and literature, and how it left a legacy of religious and political tolerance and an appreciation of diversity in the region. The demise of the Sikh Empire and its legacy in contemporary India are covered last. The paper concludes that the Sikh Empire had a significant part in shaping the Indian subcontinent's history and culture.

Arecoline is a major alkaloid of areca nuts which are widely chewed by southeast Asian and itmanifests various toxic effects in different organs of human and animals. In this work, mature micewere treated by vitamins C plus E, arecoline, or both daily for four weeks. The results showed thatarecoline significantly increased the levels of serum alkaline phosphatase (ALP), glutamate oxaloacetatetransaminase (GOT), glutamate pyruvate transaminase (GPT) and significantly decreased thelevels of reduced glutathione (GSH), glutathione-S-transferase (GST), superoxide dismutase (SOD) andcatalase (CAT) in the liver tissues. Additionally, the body weight, testis weight, sperm counts, motilityand normal sperms also were significantly decreased. The supplement of vitamins C and E can bringthe activities of ALP and GPT to normal levels and partially restore the sperm counts compared tothe arecoline-treated group but have no other positive effects. In conclusion, the vitamins C and Epartially attenuated the arecoline-induced hepatotoxiciy but basically had on protective effects againstthe arecoline-induced testicular toxicity.

This study was conducted to investigate the effects of dietary coconut oil as a medium-chain fatty acid (MCFA) source on performance, carcass composition and serum lipids in male broilers. A total of 540, one-day-old, male Arbor Acres broilers were randomly allotted to 1 of 5 treatments with each treatment being applied to 6 replicates of 18 chicks. The basal diet (i.e., R0) was based on corn and soybean meal and was supplemented with 1.5% soybean oil during the starter phase (d 0 to 21) and 3.0% soybean oil during the grower phase (d 22 to 42). Four experimental diets were formulated by replacing 25%, 50%, 75%, or 100% of the soybean oil with coconut oil (i.e., R25, R50, R75, and R100). Soybean oil and coconut oil were used as sources of long-chain fatty acid and MCFA, respectively. The feeding trial showed that dietary coconut oil had no effect on weight gain, feed intake or feed conversion. On d 42, serum levels of total cholesterol, low-density lipoprotein cholesterol, and low-density lipoprotein/high-density lipoprotein cholesterol were linearly decreased as the coconut oil level increased (p<0.01). Lipoprotein lipase, hepatic lipase, and total lipase activities were linearly increased as the coconut oil level increased (p<0.01). Abdominal fat weight/eviscerated weight (p = 0.05), intermuscular fat width (p<0.01) and subcutaneous fat thickness (p<0.01) showed a significant quadratic relationship, with the lowest value at R75. These results indicated that replacement of 75% of the soybean oil in diets with coconut oil is the optimum level to reduce fat deposition and favorably affect lipid profiles without impairing performance in broilers.
