Factors that drive Female Entrepreneurship in Armenia

Entrepreneurs play a key role in any economy. Entrepreneurship includes creativity, innovation, risk taking, planning and management and is described as transferring ideas into action. Female entrepreneurship, in particular, is considered an important tool in enabling female empowerment and emancipation. In the light of recent world events, this has become a crucial area to study and understand, especially with respect to motivations, obstacles, constraints and consequences of female entrepreneurship. Having the previous framework in attention, this thesis focuses on female entrepreneurship in a developing country - Armenia – and proposes a conceptual framework of the phenomenon. A joint cooperation between the World Bank and the European Bank for Reconstruction and Development allowed to conduct an enterprise survey in the country and from that survey a microeconomic dataset was released and applied in this research study. A logistic regression econometric method is applied to the dataset to identify and measure the relationship between female entrepreneurship and several factors such as the location, size, legal status, market and obstacles faced by Armenian firms. The study concludes that women entrepreneurs in Armenia share many common features and obstacles with their male counterparts. Moreover, gender of the top managers, the firm’s location, size, main market type, the number of competitors and full-time employees, the adoption of new marketing methods, the access to land, the tax administration system and an inadequately educated workforce are found to be statistical significant factors in the explanation of female entrepreneurship in Armenia.

Qualidade de vida da pessoa portadora de ostomia na unidade local de saúde nordeste

Uma ostomia de eliminação intestinal resulta de um procedimento cirúrgico que consiste na ligação de uma parte do intestino delgado ou grosso, a um orifício externo na cavidade abdominal designado de estoma. O utente portador de uma ostomia de eliminação intestinal, devido à sua situação clínica, manifesta um misto de emoções resultante do enorme impacto físico e emocional devido à doença e ao tratamento. A sua própria vida vai desencadear alterações profundas no seu EU, nos estilos de vida, nas relações familiares e sociais, na sua imagem corporal e na autoestima (Pinto, 2012). Foi objetivo deste estudo analisar a perceção que a pessoa portadora de ostomia de eliminação intestinal, seguida na Unidade Local de Saúde Nordeste (ULSNE), tem sobre a sua qualidade de vida (QV). A investigação enquadra-se no domínio da investigação observacional, optando-se pela realização de um estudo descritivo, analítico e transversal, de abordagem quantitativa. Como instrumento de colheita de dados foi utilizado um formulário com questões relativas às características sociodemográficas, a escala de Graffar e a escala de avaliação da qualidade de vida do utente ostomizado. Aceitaram participar no estudo 105 utentes portadores de eliminação intestinal. O sexo predominante é o masculino (50,5%). A classe etária mais representativa é a dos 65 aos 92 anos (78,1%) e o estado civil predominante antes (67,6%) e depois (55,2%) da cirurgia é o de casado. Quanto à atividade laboral, o abandono do trabalho a tempo inteiro, devido à nova situação clínica, foi referido por 94,3% dos inquiridos. Em relação às habilitações académicas, 46,7% sabe ler e escrever, enquadrando-se na classe social média (57,1%). A consulta de estomaterapia na ULSNE ainda não está implementada, mas os inquiridos consideram que a sua implementação seria pertinente (93,3%), facilitando principalmente a adaptação à nova realidade (40%), a ultrapassar dificuldades (28,6%), a evitar complicações/resolver os problemas (9,5%). A média da QV dos participantes neste estudo é de 279,92, superior à média teórica da escala (215), indicando os inquiridos evidenciam um bom nível de qualidade de vida. O enfermeiro estomaterapeuta é o profissional que melhor pode proporcionar toda a informação e suportes necessários, que permitam ultrapassar os problemas e as limitações sentidas pelo ostomizado e pelas pessoas significativas na sua vida.

Optimization of microwave-assisted extration of phenolic compounds from tomao by full factorial design coupled with response surface methodology

Tomato (Lycopersicon esculentum Mill.), apart from being a functional food rich in carotenoids, vitamins and minerals, is also an important source of phenolic compounds [1 ,2]. As antioxidants, these functional molecules play an important role in the prevention of human pathologies and have many applications in nutraceutical, pharmaceutical and cosmeceutical industries. Therefore, the recovery of added-value phenolic compounds from natural sources, such as tomato surplus or industrial by-products, is highly desirable. Herein, the microwave-assisted extraction of the main phenolic acids and flavonoids from tomato was optimized. A S-Ieve! full factorial Box-Behnken design was implemented and response surface methodology used for analysis. The extraction time (0-20 min), temperature (60-180 "C), ethanol percentage (0-100%), solidlliquid ratio (5-45 g/L) and microwave power (0-400 W) were studied as independent variables. The phenolic profile of the studied tomato variety was initially characterized by HPLC-DAD-ESIIMS [2]. Then, the effect of the different extraction conditions, as defined by the used experimental design, on the target compounds was monitored by HPLC-DAD, using their UV spectra and retention time for identification and a series of calibrations based on external standards for quantification. The proposed model was successfully implemented and statistically validated. The microwave power had no effect on the extraction process. Comparing with the optimal extraction conditions for flavonoids, which demanded a short processing time (2 min), a low temperature (60 "C) and solidlliquid ratio (5 g/L), and pure ethanol, phenolic acids required a longer processing time ( 4.38 min), a higher temperature (145.6 •c) and solidlliquid ratio (45 g/L), and water as extraction solvent. Additionally, the studied tomato variety was highlighted as a source of added-value phenolic acids and flavonoids.
