The variance based approach to structural equation modeling (VBSEM) has been widely adopted in business research field, consumer behavior, marketing, management, tourism research. The use of VBSEM in the field of E-business is also growing. Nevertheless, questions still exist among some researchers concerning whether and how VBSEM should be used. To deal with these questions, our research offers an empirical guideline for using VBSEM and employs example from the E-business literature to make obvious how the explicit points in this guideline can be applied. The foremost contribution of this research is to present an empirical guideline for evaluating and using VBSEM that is tailored to the E-business field.

Our study attempts to highlight the level of voluntary disclosure of Tunisian companies and subsequently raise the impact of several determinants on this disclosure. Our sample consists of annual reports of listed Tunisian firms relative to the year 2007. The empirical results showed that the size of the company (as measured by the number of employees), the independence of the board of directors and audit firm size have a positive and significant influence on the level of disclosure, while the age of the firm, and contrary to our hypothesis, has a negative influence on the level of disclosure. We have not been able to establish a relationship between the level of voluntary disclosure and leverage, as well as the ownership concentration and type of industry.

The current research has been carried out to realize different factors effect on project developpment. Half of the total population is represented by Women but in industry and other entrepreneurial activities, they are in few numbers. After analyzing the data it was found that most of the individuals entered into the market around the age of 37 and above. This gives an impression that individuals by the age of thirties become independent of their close environment responsibilities and left with no work. Almost every person opted for the project related to beauty-parlor and law. Educational background of the individual also seems to be quite impressive, as most of them have completed their educations up to graduation. Most of them have found to be doing household works before starting their projects. The type of project which most of them are running is of shop. This can be mainly due to the reason as before entering into project they were indulged in their household works. Most of them sell their products on the small stage. This shows that they are gradually stepping forward and try to spread their project so that it can flourish. The reason which majority of them has given to start a project was social factors. They need stimuli and support from their environment, social circles and most importantly the government.

The objective of our work is to test the presence of the contagion phenomenon caused by the mortgage American said "subprimes"crisis. First, we are going to present the effect of contagion, a literature review, and in a second part an empirical investigation on the phenomenon of crisis contagion: we applied an correlation analysis as well as an estimation of a model to error correction (asymmetric) not linear (ECM) to measure the contagion between the markets of developed countries and the emergent countries. Estimation exercises shows that there is pure contagion cases and the other interdependence contagion cases. Furthermore we found that United States are the country source of contagion during the financial crisis of subprimes. We notice the existence of the contagion in other stock market country (French, Canadian, German, British, Brazilian, Indian, Chinese, Italian and Russia). This result means that the contagion of the American financial crisis is begun with the developed countries and waq propagated in emerging countries.
