AbstractPurpose -This study seeks to examine the business and social profiles of 67 women entrepreneurs in three regions of Nigeria in order to identify patterns of entrepreneurship and social and economic challenges facing women business owners in Nigeria. The study aims to support and encourage sustainable small-scale economic development activities by Nigerian women and determine ways to integrate these small businesses into existing urban economic development projects and strategies for poverty alleviation, expand understanding of the business and social profiles of women entrepreneurs in Nigeria, examine the contextual influences on their work, raise the level of awareness of women entrepreneurs amongst all economically active agents and researchers, influence social and economic policy addressing issues of women entrepreneurs. Design/methodology/approach -A survey was developed and administered to a sample of 62 practicing Nigerian female entrepreneurs. The survey was divided into sections that recorded personal demographics, the entrepreneur's perceptions of the business environment and their venture and the motivations and drives that led to the birth of their business. Data were collected and processed to produce frequency distributions on every question/variable in the survey followed by cross-tabulations between all variables and x 2 tests in order to reveal strong associations. Findings -With no or few significant differences shown to exist between male and female business owners or managers once they have already started an enterprise, there is a strong indication that Africa has sizeable hidden growth potential in its women. From the results presented, it is evident that female entrepreneurship in Nigeria is driven by micro-financing as well as family dynamics that work to shape and influence the birth of a business. Research limitations/implications -Future research initiatives need to explore the gender dimension and the influence of education levels on the role models that influence and drive female entrepreneurship. In addition, the evolution of the complete life cycle of the entrepreneur's business should be examined and dependencies on the variables presented should...

Purpose The purpose of this paper is to explore and present current trends and developments in the field of managers’ perceptions of trust and the management of change in Cyprus, Greece and Romania, in a period of strategic organizational change. A total of 126 managerial employees (communication managers, operation managers, quality control managers, safety & environmental managers, and office managers) working in different departments of organizations in Cyprus, Greece, and Romania respond and complete the online questionnaire. Design/methodology/approach A qualitative study using an online questionnaire with interview questions was developed to arrive at the study’s findings. To acknowledge relevant perceptions of trust and the management of change during organizational change in different organizations in Cyprus, Greece and Romania, unique questions helped to support the research results and highlight themes that emerged from interview sessions with the study participants. Findings The findings highlight the need for organizational leadership to establish mutual trust and effective communication with managerial employees for successful cooperation during times of strategic change and enhanced overall employee performance. This study is relevant for researchers and academics in the areas of change management and communication, presenting current trends and developments in perceptions of trust and change management in Cyprus, Greece and Romania. It may also help them achieve recognition among their peers and colleagues from other disciplines. Research limitations/implications An important implication of the study derives from the finding on the uniqueness of the knowledge and information work carried out by the respondents and the impact that this can have in their working environment and their productivity. As a result of the above, this study provides indications to recruiters and managers regarding a number of desirable and necessary skills, and motivational factors that future employees may need to have or develop in order to carry out their job efficiently and effectively. Practical implications Researching managerial employees’ perceptions of trust and the management of change in organizations can have significant implications for human resources management during a time of strategic change. Social implications This research study may contribute to the management and communication area in European countries in stimulating new approaches to management and social issues and in the corporate management practice. Originality/value This study produces new knowledge instead of summarizing what is already known in a new form in the area of management and corporate communication. The researcher reports the results in analysis and interprets the results by discussing possible implications and solutions.
