In this paper, we present soliton-like solutions of the non-linear complex Klein-Gordon systems in 1+1 dimensions. We will use polar representation to introduce three different soliton-like solutions including, complex kinks (anti-kinks), radiative profiles, and localized wave-packets. Complex kinks (anti-kinks) are topological objects with zero electrical charges. Radiative profiles are object...

in this paper, a new smooth second order sliding mode control is proposed. this algorithm is a modified form of super twisting algorithm. the super twisting guarantees the asymptotic stability, but the finite time stability of proposed method is proved with introducing a new particular lyapunov function. the proposed algorithm which is able to control nonlinear systems with matched structured u...

Corporate entrepreneurship is a growing field of study that has been gaining ground in recent decades. Entrepreneurship exists in large and stable organizations and small and medium enterprises. Therefore, entrepreneurial business form include entrepreneurial practices in organizations, profit-making practices, and opportunity recognition. Also, entrepreneurship encourages competition in the en...

In the context of desperate poverty, characterized by households at subsistence level that experience economic loss and social fracture, explanations for why individuals undertake entry into entrepreneurship are limited. We find that individuals rely on their social relationships to enable entrepreneurial activities that have the potential to create a reasonable income gain. In a sample of 1,04...

It has been argued that if increased entrepreneurial activity is the outcome objective, then self-efficacy provides a legitimate and robust construct that can be used to evaluate the impact of entrepreneurial education (Barakat, McIellan, & Winfield, 2010). This is because self-efficacy influences the motivation and ability to engage in specific activities (Bandura, 1977) and is a strong, neces...

Air transport in Europe is experiencing unprecedented levels of demand. Industry forecasts suggest a doubling of demand by 2020. Airport managers are under increasing pressure to provide innovative infrastructural solutions in order to meet this demand. Proactively supplying capacity to air transport users can involve a degree of risk-taking. Organic organisation structures, as opposed to mecha...

Despite all efforts made by political agents to reduce the gap between regions with a high level of economic activities and those with a considerably lower one, an uneven distribution of regional success and development can be observed. For example, in Germany, there is a decline in economic activities, like innovations, employment or start-ups rates, from the south to the north and in addition...

The institutional environment – including protection of private properties and contract enforcement – has been rather unfavorable for the emergence and development of China’s private enterprises. This is in sharp contrast to the case of the developed economies where the institutional environment is conductive to the entrepreneurial activities and only the personal attributes of would-be entrepr...

Purpose: This paper aims to examine the suitability of a social enterprise model for community health promotion organisations working in disadvantaged neighbourhoods. It focuses on organisational culture, social resources and capacity as pre-requisites for entrepreneurial activities. Design/methodology/approach: This paper is based on ethnographic case studies in England including semi-structur...
