The equilibrium concentration of [Sb^3+]Twas obtained by calculation and verified by experiments. The precipitates SbOCl,Sb4O5Cl2and Sb2O3were analyzed through the equilibrium concentration of Sb^3+in the solution and the ΔrGΘmof transformation reactions of these materials. It is found that the concentration of [Sb^3+]Tin verified experiments was larger than the theoretical value, where the theoretical minimum concentration of [Sb^3+]Twas 10^-10.92mol/L at pH value of 4.6 and the minimum concentration obtained from the verified experiment was about 10^-3.8mol/L at pH value of 5.1. Different precipitates can be obtained atcertain pH. The SbOCl cannot be obtained both in theoretic calculations and in verified experiments, while the Sb8O11Cl2-H2O was generated in the experiment.展开更多

In particular, our aim is twofold: (1) to provide measures of ICE specifically tailored to professional football businesses; and (2) to empirically investigate whether some dimensions of ICE, namely, human capital and relational capital efficiency, are positively associated with sporting performance, here used as a proxy for business performance. This paper develops a quantitative analysis of club-level panel data using the statistical technique known as mixed-effects linear regression for longitudinal analysis. The research spans a time period of five years and specifically the sporting seasons from 2007/2008 up to 2011/2012. The empirical findings of this study provide tentative evidence that ICE, especially as far as relational capital is concerned, is positively associated with on-pitch performance of professional football businesses. On the counterpart, results for the impact of human capital efficiency (HCE) do not consistently come out with the (positive) expected signs. More specifically, our findings suggest that relational capital efficiency, meaning the ability to develop and nurture positive business relationship with relevant external stakeholders, is a significant consideration for football club managers; on the other, they might shed light on the actual business model of professional football clubs that, in our analysis, does not appear consistent with the long-held hypothesis of winning maximization. The main limitation of this study lies in the fact that our indicators do not fully capture all relevant dimensions of the intellectual capital (IC) construct.展开更多

Then we use t-test and nonparametric test to explore the differences between the two sub-samples in cash management, assets and liabilities structures, assets turnover ratios, profitability, liquidity and growth rates. The results show that the former has shorter Cash Conversion Cycle (CCC), quicker assets turnover, higher Debt Ratio (DR), higher growth rate and thus has better profitability. In addition, the regression analysis results further demonstrate that Return on Invested Capital (ROIC) of similar-financial-model firms are positively related to Net Profit Margin (NPM) (p 〈 0.01), and negatively to CCC (p 〈 0.01), Interest Expense Ratio (IER) (p 〈 0.01), the Ratio of Interest-Bearing Debt to Total Liabilities (IBDR) (p 〈 0.01) and the ratio of Net Receivables to Sales Revenue (NRSR) (p 〈 0.01). Moreover, negative relationship between ROIC and dummy variable GROUP implies that the former has better profitability than the latter.展开更多

However, in the process of the implementation of the new laws, the problems in view of the rules of the exclusion of the illegal evidences are also prominent, which are mainly reflected in the ambiguity of the scope of the application, the start of the program of the exclusion, and the formalization the trial certificates and other aspects. Therefore, in this article, the author starts from the concept of the illegal evidences, and expounds the principles of the exclusion and the abilities of the evidences, and especially explores the abilities of the evidences and the probative forces. From the differences between the two, the author strictly proves the virtualization of the standards, in order to provide the positive solutions for strengthening the exclusionary procedure of the illegal evidences.展开更多

The authors use data on five developed countries and five emerging countries as well as data on the Tunis Stock Exchange (TSE) after the reforms. The results show that the correlations between emerging markets returns and developed markets returns are very low and sometimes negative. Conditional arbitrage pricing theory (APT) as well as conditional CAPM has low predictive power for emerging markets than that for developed markets. Finally, following the financial reforms, Tunisian financial markets have became more and more integrated into the international market (excess returns and unconditional beta consistent with predictions). However, conditional APT does not accurately explain Tunisian market returns. This study confirms the unavailability of an accurate modelling technique of the TSE structure.展开更多

Many students have never been leaders in their social and school lives. A leading role is unimaginable to them and hence they cannot imagine how to achieve it. The purpose of this paper is to report a result of a new leadership education program which links a variety of simulated experiences with real actions of students in project based learning (PBL) to develop their leadership ability. The first step is for graduate students to gain knowledge in the leadership arena. Then, they utilize simulation to experience leadership actions many times. Simulation provides a safe environment in which they can try out many different approaches in taking leadership in various situations. In the next step, students as a team utilize PBL, so that the above simulated experiences can help them to actually take leadership. Students can apply trained leadership to actual projects. It is highly effective to apply conscious leadership to a project aimed at a specific goal in limited circumstances. This education repeats both of the steps above, raising leadership abilities in an upward spiral. In terms of students' evaluation of leadership education in project management, 360-degree assessments were carried out by teachers, senior, and junior students before and after the course, and authors compare their assessments thoroughly. As a result, authors are assured that students not only gained knowledge but also raised leadership abilities in their actions after this education. Six months after the time of leadership education employing simulated experiences and PBL, follow-up interviews were conducted on its effects. Authors recognized the cyclic period that students apply simulated experiences to PBL and that they seek different approaches in simulation for solving problems found in reality. This research concludes that this cycle of simulator and PBL can produce effective leadership actions.展开更多

Such individual differences in ways of coping with stress are relevant both in biomedicine, since different personalities may experience a different stress and disease vulnerability, and in behavioural ecology, since their adaptive value and evolutionary maintenance are the subject of debate. However, the precise way in which individual stress differences and personalities are linked is unclear. Here we provide an updated overview of this covariation across different species and taxa, consider its functional significance and present working hypotheses for how behavioural and physiological responses to stress might be causally linked, affecting life-history traits such as dispersal and life-span [Current Zoology 56 (6): 728-740, 2010].展开更多

The competitive firm invests in new productive ideas through scientific and technological researches of the human factor and services. The traditional factors of"old economy" based on physical assets have been replaced or at least reinforced, with the belief that the "new economy" takes its steps mainly through IC. The knowledge workers, at every organizational level, have the knowledge that allows the organization to be competitive and deal with the complexity of the environment by creating intellectual added value. In particular, the proposed analysis consists with an empirical way to show other financial indicators and market-to-book (MTB) value from the perspective of creating value for shareholders based on the dynamics of companies' performance, as value-added intellectual capital (VAICTM) is capable of expressing a direct relationship with the return on equity (ROE). The traditional financial information cannot ensure the high efficiency of a stock market and the need for IC reporting to explain intangible asset contribution in company performance.展开更多

The results show that the correlations between emerging markets returns and developed markets returns are very low and sometimes negative.

Finally, following the financial reforms, Tunisian financial markets have became more and more integrated into the international market (excess returns and unconditional beta consistent with predictions). However, conditional APT does not accurately explain Tunisian market returns. This study confirms the unavailability of an accurate modelling technique of the TSE structure.
