管理学视角下知行难易关系之辨

"知"和"行"是一对重要的哲学范畴,知行难易关系众说纷纭。文中根据现代管理学权变理论和沟通原理,重新解读傅说"知易行难"说、程颐"行难知亦难"说、孙中山"知难行易"说和胡适"知难行亦不易"说,并提出先贤们各不相同的知行难易学说,是基于沟通对象不同、方向不同、目的不同的主旨思想。

中国哲学史上知行观的论争

知行关系是中国哲学史上长期争论的一个重要理论问题，主要表现为知行先后，知行高低，知行难易等论争。毛泽东在《实践论》中提出的知行统一观是对中国古代知行观的批判继承和发展，并与马克思主义哲学相结合，使之成为中国化的科学的认识理论。我们把握知行理论对坚持事实求是的思想路线和提高认识能力是有意义的。

The oil refining industry will uninterruptedly rectify its industry allocation and processing unit configuration and strive for the reduction of production cost through technical progress and management innovations to reduce the production cost, boost the profitability and sharpen the market competitive edge.

Structure and behavior of floor system of two super high-speed railway Changjiang composite bridges

Wuhan Tianxingzhou Changjiang (WTC) Bridge and Nanjing Dashengguan Changjiang (NDC) Bridge are two super high-speed railway 3-trusses composite bridges. This is the first time of using three trusses in such large bridges in the world. These two types of railway floor systems of the two bridges have never been used in China before. The problem how to conform the deformations and stress levels of the railway floor system of WTC Bridge was studied. After finite element analysis and comparison,the plan of arranging one expansion stringer every two panels in railway floor system were proposed and good effect was obtained. Because of the application of three trusses,the allocation of the loads acted on the deck in three trusses is different and varies in different places of NDC Bridge. This problem was studied by model experiment and 3D finite element analysis. The results of 3D FEM analysis coincide with the model test results. The allocation rule of the loads acting on the deck in three trusses was presented. Because of the application of monolithic decks,the stiffness and structural integrity of NDC Bridge are high.

Effects of China's Administrative Approval Reforms on Transaction Cost and Economic Growth

China＇s economic growth miracle despite complicated administrative approval formalities prompted us to raise the following question： ls it true that reforming administrative approval will promote economic growth？ Based on our analysis on market entry, we discovered that reforming administrative approval will spur economic growth by reducing transaction cost for firms. Administrative approval may suppress social cost and propel China＇s economic growth; China＇s gradualist approval reforms may indeed propel economic growth by reducing transaction cost for firms. With the data of prefecture-level cities during 2000-2013 and data of companies listed on the SME board during 2010-2014, we tested the effects of approval reforms on economic growth and on transaction cost, and employed instrumental variable and PSM for the treatment of the endogeneity problem - all these tests led to robust and consistent results. Moreover, we discovered that difference in government policy implementation in the approval process is the root cause of corruption and rent seeking.

On the Reproduction Number and a Presentation of Results for Infectious Diseases Models

The classical Kermack-McKendrick homogeneous SIR （susceptible, infected and removed） model is well known, Its general solution is a function of the unique parameter （the reproduction number） that is equal to a mean number of secondary cases produced by a typical infected individual in a completely susceptible population. If the reproduction number is more than one （the threshold value） its value describes an epidemic scope： larger values correspond to more severe epidemics. In the more complex compartment SIR models the population is divided into several non-overlapping groups. It allows us to partly remove assumptions of the classical model. It is well known that for this kind of models, just as for the classical model there is the threshold parameter R0. Usually it is called by the same name--the reproduction number--though the physical meaning of this parameter has changed. The main purpose of the paper is to show that this new parameter is a not unique measure of an epidemic severity for any compartment SIR model. In particular it means that for such models comparison of the severity of two epidemics by simple comparing values of their reproduction numbers is incorrect. For compartment models these statements were proved with the help of the corresponding ODEs analysis. Very popular now individual-based models （IBMs） are more complex in comparison with the compartment ones since they use overlapping groups （school children are members of families also, for example）. In such a case Diekmann＇s calculation method for the reproduction number used in many papers is inapplicable as well as a presentation the simulation results obtained as functions of this parameter.

Research and implementation on multi-dimension trust evaluation method with web service

Integrating with practical e-commerce application, this paper introduces a novel multi-dimension evaluation method to depict and calculate the trust values. The multi-dimension evaluation metrics include functional and nonfunctional properties and corresponding weights. The continuous measurement values and the Markov chain mechanism are adopted to compute the trust value and detect the malicious behaviors. The current evaluation has larger influence factor on the next transaction behavior. A trust model is implemented with web service which consists of publication, filtrating, calculating and storage center. It is easily extended and the user only defines each property and its weights according to specific requirements, then the trust values are got. In order to conveniently manage and avoid the dead-lock, some constraint rules are proposed. The results show that the method based on multi-dimension can reflect objectively the dynamic change of trust values.

Impact of International Networks on Standardization Process in Banking Industry： Example of Secure Electronic Transaction （SET） Initiative

The purpose of this article is to present and interpret the case study of the secure electronic transaction （SET） scheme of Internet security, as an illustration of the necessary construction of interoperability solutions for financial services. The interpretation of case data with actor network theory （ANT） provides an illustration of power coalitions among banks to create a de facto standard for transnational electronic payment security on the Internet. After a step of protecting its political interests and well-known technological solutions, the coalition understands that its mission becomes a matter of life and death for its members： Brand-new currency has been invented on the Web and one could develop business and monetary transactions without the banks. This interpretative stage tells us much about the transnational mechanisms of regulation and standardization as well as the ＂translation＂ steps regarding these transnational organizations. However, an additional step has to be added to this interpretative step, a step of framework construction. The aim is to help managers of the transnational firms involved in regulations and standardization to anticipate the evolutions and make relevant decisions. The framework has three distinctive characteristics： the ability to help conception, the ability to help conceive problems ＂ex ante＂, and the ability to facilitate collective conception of strategic maneuvers.

p53 codon 72 polymorphism and liver cancer susceptibility: A meta-analysis of epidemiologic studies

AIM:To evaluate the association between p53 codon 72 polymorphism and liver cancer risk by means of meta-analysis. METHODS:Two investigators independently searched the Medline,Embase and Chinese Biomedicine databases.Summary odds ratios and 95%CI for p53 codon 72 polymorphism and liver cancer were calculated in fixedeffects model(Mantel-Haenszel method)and randomeffects model(DerSimonian and Laird method)when appropriate. RESULTS:This meta-analysis included 1115 liver cancer cases and 1778 controls.The combined results based on all studies showed that there was a statistically significant link between Pro/Pro genotype and liver cancer,but not between Arg/Arg or Pro/Arg genotype and liver cancer.When stratifying for race,similar results were obtained,i.e.patients with liver cancer had a significantly higher frequency of Pro/Pro genotype than non-cancer patients among Asians.After stratifying thevarious studies by control source,gender,family history of liver cancer and chronic hepatitis virus infection,we found that(1)patients among hospital-based studies had a significantly higher frequency of Pro/Pro and a significantly lower frequency of Arg/Arg genotype than individuals without cancer;(2)female patients with liver cancer had a significantly lower frequency of Arg/Arg and a higher frequency of Pro/Arg+Pro/Pro genotypes than female individuals without cancer;(3)subgroup analyses for family history of liver cancer did not reveal any significant association between p53 codon 72 polymorphism and liver cancer development;and(4) patients with negative hepatitis virus infection had a significantly higher frequency of Pro/Pro and a significantly lower frequency of Arg/Arg genotype than individuals without cancer. CONCLUSION:This meta-analysis suggests that the p53 codon 72 polymorphism may be associated with liver cancer among Asians.

Run-to-run Optimization for Fed-batch Fermentation Process with Swarm Energy Conservation Particle Swarm Optimization Algorithm

An iterative optimization strategy for fed-batch fermentation process is presented by combining a run-to-run optimization with swarm energy conservation particle swarm optimization (SEC-PSO). SEC-PSO, which is designed with the concept of energy conservation, can solve the problem of premature convergence frequently appeared in standard PSO algorithm by partitioning its population into several sub-swarms according to the energy of the swarm and is used in the optimization strategy for parameter identification and operation condition optimization. The run-to-run optimization exploits the repetitive nature of fed-batch processes in order to deal with the optimal problems of fed-batch fermentation process with inaccurate process model and unsteady process state. The kinetic model parameters, used in the operation condition optimization of the next run, are adjusted by calculating time-series data obtained from real fed-batch process in the run-to-run optimization. The simulation results show that the strategy can adjust its kinetic model dynamically and overcome the instability of fed-batch process effectively. Run-to-run strategy with SEC-PSO provides an effective method for optimization of fed-batch fermentation process.

Cultural study on trade disputes between China and the West

In recent years, China＇s international trade has made great actuevements, However, when carefully reviewing its performance in the international market, we have to admit a fact that ＂Chinese businessmen＂ and ＂Made in China＂ are encountering great challenges, even aversion in many foreign markets. The so-called ＂Yellow peril theory＂ and ＂China threat theory＂ have caught on once again. Faced with such frequent trade conflicts, we fall into contemplation. Why did trade conflicts so frequently happen？ Do these conflicts merely remain at the commercial level？ Or, are there any deep-seated conflicts leading to trade conflicts？ What are the root causes of these conflicts？ How to overcome and avoid these conflicts in the future？ With these questions, this paper is designed to inquire into the root cause of trade conflicts and the constructive suggestions to settle trade conflicts from a cultural perspective.

Politeness Strategies in Refusal

The theory of politeness and face-saving proposed by Brown and Levinson （1978, 1987） has been up to now the most influential politeness model. Brown and Levinson＇s politeness theory contains three basic notions： face, FTAs （face threatening acts）, and politeness strategies. According to the authors, ＂face＂ refers to the public self-image of a person. Negative face shows the need to be independent, to have freedom of action, and not to be imposed on by others. Positive face shows the need to be accepted, even liked, by others, to be treated as a member of the same group, and to know that his or her wants are shared by others. It plays a leading role in the study of speech acts Brown and Levinson introduced five super strategies for politeness in relation to FTAs： bald on-record, positive politeness, negative politeness, off-record, and don＇t do the FTAs. The theoretical framework of this paper is based on Brown and Levinson＇s politeness theory and strategies

Investigating Voluntary Risk Disclosure： The Case of Jordanian Banks

The aim of the study is to investigate whether banks in Jordan are compliant with the International Financial Reporting Standards （IFRS） 7 requirement for mandatory disclosure and to find out the extent to which the banks provide voluntary risk disclosures. To achieve the objectives of the study, we collected data from all 15 banks listed on the Amman Stock Exchange for the year ending December 2013. The findings of the study suggest that there is strong compliance with respect to mandatory risk disclosure, as required by IFRS. However, the results generally signal a need for further improvement in the voluntary risk disclosure area, since most of the banks do not provide adequate information that can be of use to stakeholders. We also suggest future avenues of research into the topic to determine progress.

Learning by Doing Effect in North South Trade under the Global Value Chains： An Empirical Analysis of Various Industries in the U.S.

This paper studies the division of labor and economic development under global value chains in North South trade by mainly investigating the changes of production hours and cost per unit along with more and more output and increasing trade value in several industries in the U.S., because the U. S. is at the leading position in the division of labor by global value chains. The empirical evidence reveals that more international outsourcing, there will be more detailed division of labor, and the industry unit production time and production cost will show more declining trend year by year. This is consistent with that the global value chains and the outsourcing play more and more important roles in the international division of labor and economic growth in both developed and developing countries, and helps explain the integration of workforce across countries in the global value chains.

Policy Implications for Carbon Trading Market Establishment in China in the 12th Five-Year Period

Based on the survey of international emissions trading system （ETS） and quantitative analysis, policy suggestions on establishing a carbon ETS in China are presented in this study. Sectors sensitive to carbon prices, e.g., the power generation sector and the iron and steel industry, are given priority to be covered by the ETS. Interregional carbon trading should be carried out as early as possible. The cap of the ETS should be based on China＇s carbon intensity reduction target with the floor carbon price for the market being set in the beginning. Suggestions on the infrastructure of ETS are also proposed, including the national wide carbon measuring, reporting, verification system building. account registration system and the legislation to national

Physico-mechanical performance of debris-flow deposits with particular reference to characterization and recognition of debris flow-related sediments

To characterize and recognize the debris flow-related deposits,the physico-mechanical performance of four deposits from the Dongyuege(DYG),Shawa(SW),Jiangjia Gully(JJG),and Gengdi(GD)debris flows in southwest China is investigated through laboratory analyses and tests.The four debris-flow materials can all be remolded into coherent,homogeneous cylinders with high densification and strength–porosity of 25%-36%,mean pore-throat radius of 0.46-5.89μm,median pore-throat radius of 0.43-4.28μm,P-wave velocity of 800-1200 m/s,modulus of elasticity of 28-103 MPa,unconfined compressive strength(UCS)of 220-760 kPa,and cohesion of 65-281 kPa.Based on the comparison in slurryability and formability among debris-flow deposits,granular flow deposits,fluvial deposits,residual lateritic clay and loess,whether a sediment can be cast into competent cylinders for physico-mechanical tests can be regarded as a diagnostic evidence of old debris-flow deposits.The discrepancy in physico-mechanical properties among the four debris-flow deposits suggests that the combination of foregoing physico-mechanical parameters can characterize assembling characteristics of debris flow-related sediments including grain size distribution,mineralogy,and accidental detritus.Four deposited sediments above can be surprisingly classified as hard soil-soft rocks according to UCS,and the hard soil-soft rock behaviors can advance the further understanding of debris flows.
