Such pressures require effective leadership to lead, change, and improve enterprise performance in order to meet the demand for current and future business. Many of the new changes that are occurring in business today are transformational. They are driven by the environment and client need. The entrepreneur may not know the exact outcome at first, because it emerges throughout the process. It requires a fundamental change in their mindset and organizational culture, and requires continual course corrections to the change process. This research was conducted to help the aspiring entrepreneurs to develop and improve their leadership style. One hundred and fifty successful Bicolano entrepreneurs were surveyed and interviewed about their actual leadership styles and practices and this was the basis for developing a leadership program for aspiring or future entrepreneurs. Transformational leadership was the leadership style fairly often use of the successful entrepreneurs and this is characterized as being optimist about future of their business, enthusiastic about what needs to be accomplished, articulate a compelling vision of the future and expresses confidence that goals will be achieved.展开更多

The third-party legislative post-assessment can overcome the drawbacks of self-assessment, realizing the public participation better, which makes results of the assessment more objective, neutral and fair. The neutrality of assessment and scientificity of the method should be adhered in the construction of third-party legislative post-assessment in China, while improving public participation as well as the assessment indicators system and quality control system with the introduction of specific legal norms.展开更多

Under more than 20 years of development which begins to bud in the beginning of the nineteen nineties, the assets valuation industry has become the indispensable Intermediary trade of the socialist market economy system in China. With the scale of assets valuation agency enlarging and its rapidly growing business in recent years, however, some problems have been exposed gradually, which harm the social image of the industry of asset valuation seriously. So the social public and the relevant administrative departments pay close attention on the quality of the asset valuation. To know about what are the essential causes that affect the assets valuation industry managers' decision, this paper, through using some means which include literature research, interview and questionnaire investigation and utilizing the method of the factor analysis, relegates 24 questions which come from some answers of the respondents to three factors which are the practicing quality factor, the sting factor of an organization and the internal management factor of valuation organization. Furthermore, it will analyze the features of these factors which are divided into two factors that are internal motivation and external motivation, looking for the key cause of the assets valuation industry quality problem of China which purposes in order to promote the healthy development of valuation profession and much better standard the internal quality of valuation industry of China.展开更多

Furthermore, we examine the differences between the line widths of Hβ and Mg II in detail by comparing their line profiles. The flux around the line core and that in the wing of both Hβ and Mg II show an opposite variation tendency, which indicates the BLR is multi-componential. The contribution of the wing makes the FWHM deviate from δline, and thus bias the MBH estimated from previous single-epoch mass estimators. Thus the correction on the formalism suggested by Wang et al. is crucial to MBn estimation.展开更多

The system is under an external electric field directed along the-x direction. First, we have solved the Schr¨odinger equation using the finite element method. Then, we have used the Tsallis formalism and calculated the entropy of the system for different temperatures, electric fields and impurity locations. It is found that the entropy decreases with increasing the electric field and temperature. Since the electric field directed along the-x direction, the entropy reduces when the impurity moves toward the left hand side.展开更多

We then investigate the cosmological evolution of f(T) massive gravity, and constrain it by using the latest observational data. We find that it slightly favors a crossing of the phantom divide line from the quintessence-like phase (wae 〉 -1) to the phantom-like one (wae 〈 -1) as redshiff decreases.展开更多
