Methods Case-control studies on relationship of Thr307Ala and Asn680Ser polymorphisms in FSHR gene and PCOS susceptibility were searched from PubMed, ISI web of knowledge, EBSCO, and China National Knowledge Infrastructure (CNKI) databases up to March 21, 2013. The pooled odds ratio (OR) and 95% confidence interval (CO were calculated using fixed- or random-effect model based on heterogeneity test in 5 genotype models analyses. Results A total of 11 studies were included in the Meta-analysis. The random-effect analysis showed Asn680Ser was significantly associated with the reduced susceptibility to PCOS with dominant model (Asn/Asn+Asn/Ser vs. Ser/Ser, OR=0.83, 95% CI: 0.69-1.00), recessive model (Asn/Asn vs. Asn/Ser+ Ser/Ser, OR=0.84, 95% CI: 0.72-0.98), homozygote comparison (Ash/Ash vs. Ser/Ser, 0R=0.79, 95% CI: 0.63-0.98), and the allele contrast (Asn vs. Ser, OR=0.87, 95% CI: 0.79-0.97) respectively(P=0.02, I2=56.0%), being protective factors for PCOS. However, no significant associations were found between Thr307Ala and PCOS. Conclusion There might be a significant association between Asn680Ser polymorphism and PCOS.展开更多

AIM: To assess the association between Interleu-kin-10 (IL-10) gene IL-10-1082 (G/A), IL-10-592(C/A), IL-10-819 (T/C) polymorphisms and hepatocellular carcinoma (HCC) susceptibility.METHODS: Two investigators independ...AIM: To assess the association between Interleu-kin-10 (IL-10) gene IL-10-1082 (G/A), IL-10-592(C/A), IL-10-819 (T/C) polymorphisms and hepatocellular carcinoma (HCC) susceptibility.METHODS: Two investigators independently searched the Medline, Embase, China National Knowledge Infrastructure, and Chinese Biomedicine Database. Summary odds ratios (ORs) and 95% conf idence intervals (95% CIs) for IL-10 polymorphisms and HCC were cal-culated in a fixed-effects model (the Mantel-Haenszel method) and a random-effects model (the DerSimonian and Laird method) when appropriate. RESULTS: This meta analysis included seven eligiblestudies, which included 1012 HCC cases and 2308 controls. Overall, IL-10-1082 G/A polymorphism was not associated with the risk of HCC (AA vs AG + GG, OR = 1.11, 95% CI = 0.90-1.37). When stratifying for ethnicity, the results were similar (Asian, OR = 1.12, 95% CI = 0.87-1.44; non-Asian, OR = 1.10, 95% CI = 0.75-1.60). In the overall analysis, the IL-10 polymorphism at position -592 (C/A) was identified as a genetic risk factor for HCC among Asians; patients carrying the IL-10-592*C allele had an increased risk of HCC (OR = 1.29, 95% CI = 1.12-1.49). No association was observed between the IL-10-819 T/C polymorphism and HCC susceptibility (TT vs TC + CC, OR = 1.02, 95% CI = 0.79-1.32).CONCLUSION: This meta-analysis suggests that IL-10-592 A/C polymorphism may be associated with HCC among Asians. IL-10-1082 G/A and IL-10-819 T/C polymorphisms were not detected to be related to the risk for HCC.展开更多

In the past decade, both developing and developed WTO member nations have debated whether the TRIPS agreement should expand its definition to cover new areas such as genetic resources and traditional knowledge. This article argues that although the genetic resources-based market is huge, developing countries have benefited little from it. Specifically, the current market mechanism and system provide little incentive to developing countries to protect biodiversity. Expanding TRIPS to cover new areas such as genetic resources and traditional knowledge can make multilateral trade fairer and more balanced and will enable developing members to better protect biodiversity.展开更多

The author considers the example of Louis XIV. It seemed that he held the sovereignty as the king of the absolute monarchy and the greatest freedom. But all his teeth were pulled out to protect him from illness and in his exercise as the king, he had many official obligations. Though he was king, he was free and lacked freedom. According to J. J. Rousseau (1762) who discussed the principle of freedom and oppression (deprivation), if man realizes freedom, it needs to express his duty and subordination to the state. Therefore man is free and lacks freedom. What is the situation of contemporary citizens? Instead of the oppression by the state, the citizen is controlled by the mass media. The best example is the drama observed about the prime ministers of Japan. There were many manipulations by the mass media. For our benefit we need to educate the persons who have good sense. We should remember that our freedom is not absolute. We are free and lack freedom, too. Often man searches freedom and comfort but often, on the contrary, he faces the lack of freedom. Electricity that is produced by a nuclear plant is useful, but the explosion of the nuclear plant creates a huge damage and tragedy, In a sense, deprivation is larger than freedom, because it could teach us self- awareness, moderation and let us know that we have enough.展开更多

Being formalized the propositions will be deduced from how probabilities can be used to make decisions by appropriating Hegel's concept of being two-sided for inferences. This will work for what I will call grounded as opposed to ungrounded probability functions. The domain of their values will be decided by a three-valued modal relation of the binomial probability function. Keynes (1920, Ch. IV ~17) and Popper's (1959, Ch. 59) solution to the problem of unknown proportions will be challenged by an understanding of logic that puts the content of what the axioms mean for making rational decisions before their mere being. What is true for the different types inferences will then work for the principle of the dialectic in contrast to the two proposed by Hume and the one proposed by David Lewis. In this way, it will be demonstrated that Hegel's understanding of logic is still more advanced than one that fails to recognize it falls within the scope of the dialectic. Dialectic as such will be a principle where the different understandings of a predicated logic will have a modal value within a higher standpoint of system.展开更多

In spite of its clear contribution to a firm's sustainability of performance, recognition of these intellectual assets in the financial statements do not correspond with their significance as they have to rigid criteria set by conventional accounting standards. This study seeks to assess the level of intellectual capital (IC) resources reported in Malaysian companies in the traditional sectors of the economy and examine their reporting trends in the annual reports of these companies from years 2003 and 2008 Data was collected from companies listed in the main board of Malaysia Stock Exchange (or Bursa Malaysia) and content analysis was applied. Results show that the extent of IC reporting in the annual accounts of listed companies in traditional sectors is slightly above average.展开更多

The review of literature provided conceptual and empirical gaps that formed the basis of the conceptual hypotheses. Two hypotheses were deduced from general objective: Intellectual capital has a significant influence on corporate performance; corporate culture moderates the relationship between intellectual capital and corporate performance. A cross-section research design was adopted. A survey questionnaire was the main tool of data collection and was distributed to the 50 heads of human resource departments in the different firms' period covering four financial years from 2009 to 2012. The study also utilized secondary data obtained from Capital Market Authority Statistical bulletins and Nairobi Securities Exchange Handbook 2012-2013 to collect data on financial performance (ROA, ROE, and Dividend Yield). Data were tested for reliability results showing that study dimensions were reliable, apart from task-oriented culture that had a Cronbach alpha of 0.262, thus being not considered for further analysis; thus the study relied on employee-oriented culture as a measure of corporate culture. The hypotheses were tested using multiple regression analysis and hierarchical regression respectively. Multiple regression analysis showed that intellectual capital had a significant influence on non-financial performance and no significant influence on financial measures of performance (ROA, ROE, and Dividend Yield). Test for moderation showed that the interaction term was not significant and thus, employee-oriented culture did not moderate the relationship between intellectual capital and corporate performance. The study demonstrates importance of the influence of intellectual capital on non-financial performance of firms listed on Nairobi Securities Exchange. The results show that interplay among human capital, social capital, and organization capital is important for firms listed on Nairobi Securities Exchange and that the firms should nurture the employees into sharing their knowledge by creating internal and external networks and also creating support system within the organization to retain the knowledge.展开更多

In this paper, the issues currently facing vocational English education was of, and the corresponding countermeasures. With the development of economic and trade globalization, increasingly strengthened international exchanges. Society is not only high-level personnel to graduate raised higher and higher English proficiency requirements, the ability to develop applications based English Education in Higher Colleges also put forward higher requirements. Vocalional Training Colleges for professional and technical personnel is an important part of our personnel training requirements for rapid economic development of professional and technical personnel in addition to high technical expertise, but also need to understand the professional literature information inquiry, learning and further education. Therefore, we must from the height of the times and the needs of international competition to recognize new opportunities and challenges of English teaching in higher vocational colleges are facing a variety of approaches and strive to improve our English teaching level.展开更多

On 15 May 2017, the Joint Communique of the Leaders Roundtable of the Belt and Road Forum for International Cooperation reaffirmed the participants' shared commitment to build an open economy and ensure free and inclusive trade. The Belt and Road Initiative (BRI) is not only China's new action to drive its open and global develoPment, but also a platform for an increasing number of countries to explore free and inclusive trade and promote a universal, rule-based, open, non-discriminatory, and equitable multilateral trade system. It is therefore important to examine BRI and global trade networks. More specifically, the topological relationship between the this article first analyzes the community structure of trade networks using a community detection algorithm, and then estimates the topological relationship between different trade communities. The findings of this article are as follows. First, this research identified three trade communities and two sub-communities in the BRI trade network, in which China is the core, Russia is the sub-core of the biggest trade community, and India, United Arab Emirates, and Saudi Arabia are cores of the second trade community (South Asia-West Asia). Second, it identified five trade communities in the global trade network, centred on China, USA, Russia, India-United Arab Emirates, and Ger- many-Netherlands-France-Britain and other European developed countries. Third, the topo- logical analysis indicated that in the global trade network, most BRI countries are attracted by the core nodes of the BRI regions, such as the China, Russia and India-United Arab Emirates core nodes, and have strong trade contacts with BRI countries. Most Central-East European countries are mainly attracted by Germany-Netherlands-France-Britain and other developed European countries with a low penetration of BRI trade. Although some Southeast Asian countries are incorporated into the Asia-Australia-South Africa community with China as the core, they still need to strengthen trade linkages with BRI countries.展开更多
