Entrepreneur's and SME's characteristics and competitive advantage. A kind of roadmap to SME's success
No full textPurpose of this study is to highlight some of entrepreneur’s and sme’s characteristics that are sources of competitive advantage. Further, the sources of competitive advantage drive to it. Thus, via the obtainment and maintenance of a diachronically long-term competitive advantage, a small business can achieve the principal objective of a firm which is maximization of its wealth and continuous stay on profit areas.
Plethora of resources and competences were proposed as sources of competitive advantage in resource-based view and add continually new ones. It appears to suffer hierarchy of sources of competitive advantage regarding sustainability of these.
Literature about sme and entrepreneur emphasizes the significant role of certain factors such as business size, management, ownership, data relating to the survival and competitiveness of sme, sales, profitability, liquidity, lack of skilled personnel, distribution channels data and market information, potential fundraising, use of innovation or new technologies, organizational structure, resources control, networking and clustering.
Between factors that make up features of a successful small business are these influencing business size of sme, such as characteristics of entrepreneur, management strategies, external environment’s influence, and sme’s characteristics.
Little difference exists between sme’s failure and success. Apart from environmental factors, there are three categories of failures mentioned: functional knowledge, managerial skills and managerial behaviour, related to entrepreneur’s and sme’s characteristics
The relarionship between minimum wage and unemployment rate in greek labour market
No full textIn Greece, during the last four years, have been legislated and implemented a series of legislative provisions introducing
some significant structural changes in the Greek labour market. These changes had to do, among others, with the reduction
of minimum wage level compressing the labour cost companies in order to increase the employment rate. The views of
economists on effect of the establishing of minimum wages are quite contradictory. The evaluation of relationship between
labour market and minimum wage rate is either positive or negative or even not related at all, depending on the assumptions
about characteristics of labour market.
The purpose of this paper is to investigate the relationship between the minimum wage level and the rates of unemployment
and employment in the Greek labour market. More specifically, this study analyses the evolution of the minimum wage
during the period 2000-2013 and also whether these changes have really affected the unemployment and employment rates
or not. The main conclusion of our study supports several other studies conclusions suggesting that the level of minimum
wage in Greece did not really affect the unemployment and employment rates
Flexible working and unemployment in Greece: An analysis and review of the evidence
Get PDFIn recent years, particularly in the European Union, it is believed that the reduction of labor costs will contribute to the competitiveness and adaptability of enterprises and thus to maintain existing and create new jobs. Since the early 1990s, Greece following the guidelines of the European Union, gradually pushed a series of legislative changes relating to payments, working time, etc. aiming to promote flexible working.
This paper examines the relationship of flexible working, employment and unemployment in the Greek labor market. More specifically, we study the evolution of flexible forms of employment during the period 2000-2013 and examine whether these changes had an impact on the overall scale of employment and unemployment. The main conclusion of the study supports findings of other researches that the significant increase in flexible working, particularly after 2009, failed to increase employment and reduce unemployment in the Greek labor market
Evaluation of High Educational Institutes economic impact with Satellite Accounting: an empirical application in Greece
No full textThe purpose of this article is to show how to evaluate the various economic impacts generated by the establishment and operation of high educational institutes (HEIs) on a local economy and how HEIs affect the national economy, particularly that of Greece. The methodological framework used in this paper is the Satellite Account for Education (SAE) which has not been yet developed in Greece and therefore consists of a proposed methodological framework based on international human accounting rules and principles. The empirical application concerns the effect of the Technological Educational Institute (TEI) of Epirus on the local economy of the Preveza prefecture through measuring the effect on consumption, GDP, local income, value added tax, and employment. The outcomes of the research are important to the government and education policymakers, especially since Greece faces enormous public finance problems and problems with the transformation of the tertiary education system
Female entrepreneurship in primary sector of Municipality of Pogoni
No full textInternational reclassifications effected in rural economy, through the process of globalization, have also influenced Greek rural space. In this environment, role of woman and female entrepreneurship have been diversified.
Rural women in modern Greek society play a multitude of social and economic roles in rural development and often represent a potential with a series of special abilities and skills which can be used for rural development.
Purpose of this field research is the study of the multifunctional role of rural women both in rural development and primary sector’s businesses. The survey was conducted in second semester of 2012, in Municipality of Pogoni, a remote area with increased importance in Prefecture of Ioannina – Region of Epirus, Greece – by personal interviews and questionnaire, containing closed and open-ended questions, with rural women aged 18-65 years, holding a small business in primary sector. Thus, results about entrepreneurship and female particularly are unique for this specific rural area.
Analyzing interviews’ results about women’s opinion concerning fields of agriculture, livestock, agritourism, etc., it is concluded that within modernization of primary sector, the role of rural women has greatly improved in production and organization of agricultural labor.
Female entrepreneurship networking (cooperatives, clustering), small businesses’ succession, and necessity and opportunity entrepreneurship in primary sector’s businesses are examined and also how these affect female entrepreneurship.
Women entrepreneurs’ opinions about their smes, E.U. measures, agriculture, quality of life in rural area, and their perspectives were catalogued.
Factors such as education and vocational training are important in enhancing the role of rural women.
Finally, main problems woman entrepreneur faces, mainly economic and managerial, were pointed out
Optimization of piezoelectric patches in smart structures using multi-objective genetic algorithms
Get PDFIn this paper multi-objective genetic algorithms have been used to search for the optimal placement of the piezoelectric sensors and actuators bonded on smart beams. A finite element method based on Timoshenko beam theory is used accounting for the piezoelectric layers. The discrete optimal sensor and actuator location problem is formulated in the framework of a zero-one optimization problem with multi-objective functions as performance measures. A cantilever beam example is considered to demonstrate the performance of the selected multi-objective genetic algorithm which is NSGAII. It is shown that the proposed algorithm is effective in developing optimal Pareto front curves for optimal placement and number of actuators and sensors such that the performance on dynamic responses is also satisfied
DAG Scheduling using Integer Programming in heterogeneous parallel execution environments
Get PDFhttp://www.alma-project.eu/downloads/Mista2013.pdfA computer program can be represented by a Directed Acyclic Graph (DAG) in
order to capture the dependencies between the individual tasks that should be executed each
time the program runs. This paper proposes a mathematical model of Integer Programming that
can be applied in order to schedule the tasks in the presence of multiple processors serving as
the execution environment. The target is to minimize the overall execution time of the DAG
known as schedule length or makespan. An approach called MATH using the full model is
applied to small sized problems and then a more elaborate approach called MATHL is
presented where the DAG is partitioned to levels. Levels are formed according to the hops
needed for each node to be reached starting from the source node. Hence sub-problems have
manageable size and can be solved in a timely manner. Consecutive optimal solutions for each
level result in a high quality schedule for the overall problem even for cases consisting of
several hundreds of nodes. Results show that this method constantly gives very good results
and it is compared favorably with other approaches to the problem that can be found in the
