Most of the current researches on online ads auction focus at the point of linear programming or assignment problem, while there's little study on the macro-level auction mechanism, especially the characteristics of the general winning bids. Based on real log data from a DSP in China, this paper conducts empirical analysis of average deal price and bidding volume at different times of impressions. Finally, we design an optimized method for delivery of RTB ads through offline experiments.","PeriodicalId":197239,"journal":{"name":"2014 International Conference on Management Science & Engineering 21th Annual Conference Proceedings","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116053300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the Variation-Selection-Retention theory of creativity, this study expands the research viewpoint to the outside of job context by discussing the moderating effect of cognitive irritation on the relationship between job control and employee creativity. To test proposed model, we collected empirical data from 267 employees in Korea. The model constructed was tested with hierarchical regression. The empirical results showed that job control has a positive effect on the employee creativity; cognitive irritation as a moderator can strengthen the positive relationship between job control and employee creativity. Implications for enhancing the employees' control and guiding their irritation properly in organizations are discussed.","PeriodicalId":197239,"journal":{"name":"2014 International Conference on Management Science & Engineering 21th Annual Conference Proceedings","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133006864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional measures for mutual funds performances are very sensitive with the bias, resulting from the variation of risk and risk-premium with time. In order to balance these kinds of variations, lagged public information factors may be helpful. Including short-range UK Treasury Bill (Rf) and dividend yields (DY), different fund returns are predicted with additional information. This paper empirically estimate the average performance of 68 UK close-end mutual funds invested in domestic market over a meaningful decade-period from 2000 to 2010, applying the traditional and conditioning versions of capital asset pricing model and Fama-French model. Meanwhile, Jensen's (1968) traditional strategy and conditional measure of Ferson and Schadt (1996) are involved followed by a set of time-series regressions in order to compare different measure's significance in T test and F test. The findings are that CAPM not only has higher fitness butt also decreases the minus bias of market timing when adds conditional information. However, FF models show contrast evaluation and unexpected inferior outlets based on UK mutual funds between 2000 and 2010.","PeriodicalId":197239,"journal":{"name":"2014 International Conference on Management Science & Engineering 21th Annual Conference Proceedings","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125946032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to build a wealthy, sustainable and harmonized society, China is in great need for reliable renewable energies. Although China has published the Law of Renewable Energy, the implementation of it meets some difficulties. The authors first introduce the current renewable energy policies, then take Xinjiang's wind energy policy implementation as an example. Xinjiang is a very resourceful province and it is one of the largest wind energy potentials of China. The development of renewable energy in Xinjiang were hampered by the decrease of interest in renewable energy due to other non-energy-related issues. This leaded to the fact that governmental officials did not focus much on the development of renewable energies and therefore renewable energy policies were not well implemented at all. Outdated facilities and techniques were other important factors that affect the implementation of renewable energy polices. The authors give some suggestions to solve the problems from this two perspectives.","PeriodicalId":197239,"journal":{"name":"2014 International Conference on Management Science & Engineering 21th Annual Conference Proceedings","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115339102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study finds that female-group auditors' audit fees are significantly higher than those of the nonfemale-group auditors', which may be due to female auditors' preference to take more audit procedures and use more personnel to reduce the audit risk.

In this paper, the relationship between capital structure and profitability of listed company in the pharmaceutical industry is under discussion. In the context, we select 141 pharmaceutical industry listed companies as the research objects. Through the model and principal component analysis, we use the total score to assess profitability, then adopt multiple regression method for regression analysis. The research result shows: asset-liability ratio of listed companies is negatively correlated with the profitability in the pharmaceutical industry. The relationship between long-term asset-liability ratio and profitability is not significant. The proportion of professional major shareholders and profitability is related. Ownership concentration is positively associated with profitability. The consequence is probably conducive to regulate financing behavior in China and boost the competitiveness of enterprises. Some suggestions are submitted which help to improve listed company's ability in China's pharmaceutical industry to fight against risk. In addition, we hope it provides theoretical help for investors and other important stakeholders to make decisions. Therefore, the study of the relationship between capital structure and profitability appears to be of great significance for Chinese pharmaceutical listed companies.","PeriodicalId":197239,"journal":{"name":"2014 International Conference on Management Science & Engineering 21th Annual Conference Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129699499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
