An Empirical Investigation of Female Entrepreneurship & Innovation Activities in Greece

The importance of entrepreneurship for economic growth has been emphasised by economic literature. The recent debate on the determinants of output growth has concentrated mainly on the role of knowledge, typically produced by a specific sector of the economy, and furthermore in the role of entrepreneurship and the implications on economic growth. Much of the recent work on economic growth can be viewed as refining the basic economic insights of classical economists. The statistical analysis is therefore very important. Nowadays there are well-organized databases, and the researcher can easily decide about the sample, rather than some years ago. Research and Development, technical change and entrepreneurship are directly related with industrial infrastructure, productivity effects and regional development. Entrepreneurship aims to reinforce the competitiveness, and to succeed the modernisation process and the convergence between firms and industries in the member states, adopting statistical techniques, using the appropriate software. This paper attempts to examine the role of entrepreneurship, and those of innovation activities (technical change, research and development and diffusion of technology) and the effects of output growth, using both a theoretical and empirical approach in a Greek case study. In particular, the purpose of this paper is to analyse the framework, the obstacles, the determinant factors using the appropriate statistical techniques and furthermore the role of female entrepreneurship in the Greek firms. It also attempts to examine the role of female entrepreneurship on innovation activities and the effects on sustainable development and in the implications on growth, economic integration, regional development and social change.

Mathematics vs. Statistics in tackling Environmental Economics uncertainty

In this paper the appropriate background in Mathematics and Statistics is considered in developing methods to investigate Risk Analysis problems associated with Environmental Economics uncertainty. New senses of uncertainty are introduced and a number of sources of uncertainty are discussed and presented. The causes of uncertainty are recognized helping to understand how they affect the adopted policies and how important their management is in any decision-making process. We show Mathematical Models formulate the problem and Statistical models offer possible solutions, restricting the underlying uncertainty, given the model and the error assumptions are correct. As uncertainty is always present we suggest ways on how to handle it

Karl Stellwag von Carion (1823-1904) and his studies on clinical and pathological anatomy of ocular cancer

Karl Stellwag von Carion (1823-1904) was a very important figure of European ophthalmology during the 19th century. Besides his other contributions in ophthalmology such as ‘Stellwag sign’, coining the term ‘ectopia lentis’ for lens dislocation and fundamental studies on glaucoma, refraction, accommodation and light polarization, his studies on ocular cancer were very significant but not highlighted by modern research

Complex chromosome rearrangement in a child with microcephaly, dysmorphic facial features and mosaicism for a terminal deletion del(18)(q21.32-qter) investigated by FISH and array-CGH: Case report

We report on a 7 years and 4 months old Greek boy with mild microcephaly and dysmorphic facial features. He was a sociable child with maxillary hypoplasia, epicanthal folds, upslanting palpebral fissures with long eyelashes, and hypertelorism. His ears were prominent and dysmorphic, he had a long philtrum and a high arched palate. His weight was 17 kg (25th percentile) and his height 120 cm (50th percentile). High resolution chromosome analysis identified in 50% of the cells a normal male karyotype, and in 50% of the cells one chromosome 18 showed a terminal deletion from 18q21.32. Molecular cytogenetic investigation confirmed a del(18)(q21.32-qter) in the one chromosome 18, but furthermore revealed the presence of a duplication in q21.2 in the other chromosome 18. The case is discussed concerning comparable previously reported cases and the possible mechanisms of formation
