Attitudes and perceptions regarding entrepreneurship around the world : a cluster analysis approach

Nowadays it is believed that entrepreneurship could be a driving force in growth and development. For the achievement of a relevant national entrepreneurship rate the social and economic business environment can be crucial. However, despite the international attention given to entrepreneurship, it is not known if it is a global phenomenon or if there are particular regions where the entrepreneurial activity is specially recognized by society. Applying cluster analysis statistical techniques to a dataset gathered by the Global Entrepreneurship Monitor (GEM) and that includes, in 2010, 59 countries this paper intends to identify groups of countries with the same population attitude and perception regarding entrepreneurship

A fuzzy knowledge-based framework for risk assessment of residential real estate investments

Risk analysis of residential real estate investments requires careful analysis of certain variables (or determinants). Because real estate is a key sector for economic and social development, this risk analysis is seen as critical in supporting decision processes relating to buying or selling residential properties, partly due to the pressures caused by the current economic environment. This study aims to develop a conceptual reference model for risk assessment of residential real estate using fuzzy cognitive mapping. This fuzzy model allows cause-and-effect relationships between determinants to be identified and better understood, which in turn allows for better informed investment decisions. The results show that the use of cognitive maps reduces the number of omitted criteria and favors learning with regard to how the criteria relate to each other, holding great potential and versatility in structuring complex decision problems. Practical implications, strengths and weaknesses of our proposal are discussed

Comparative analysis of the definitions of logistics centres

A logistics centre is a center for all the companies which participate in activities related to transport and logistics in the broadest meaning. LCs provide collective equipment needed to develop these activities and have common services for the companies installed there. Together with the values of location and centrality a logistics centre provides quality service and effective selection of the most efficient means of transportation due to its truly multi-modal transport possibilities

Economical evaluation of logistics centres establishment

This paper presents a method for assessing the financial viability of a new Freight village financed by private and public investments. The financial evaluation model constitutes four distinct phases, namely (a) site selection and traffic forecasts, (b) definition of services offered and corresponding dimensions, (c) estimation of investment and operation costs and (d) evaluation of investments. Furthermore, the model produces financing scenarios, based on combinations of public and private funds

EVALUATION SYSTEM FOR FACTORS AFFECTING CREATIVITY IN THE LITHUANIAN ARMED FORCES / KŪRYBIŠKUMĄ VEIKIANČIŲ VEIKSNIŲ VERTINIMO SISTEMA LIETUVOS KARIUOMENĖJE

Nuolat kintančioje aplinkoje keičiasi kūrybiškumą veikiantys veiksniai ir jų vertinimo būdai, kurie mokslinėje literatūroje bei praktikoje vertinami kontraversiškai. Įvairūs autoriai skirtingai vertina ir interpretuoja kūrybiškumą skatinančius veiksnius. Todėl kyla problema - kaip identifikuoti ir įvertinti, kuris požiūris tiksliau ir išsamiau atspindi bei perteikia tikrovę. Šios problemos nagrinėjamos jungiant skirtingų autorių pozicijas kūrybiškumą skatinančių veiksnių identifikavimo ir vertinimo aspektais. Straipsnio tikslas - suformuoti kūrybiškumą veikiančių veiksnių vertinimo sistemą Lietuvos kariuomenėje. Šiems veiksniams identifikuoti ir vertinti taikyti ekspertiniai, daugiakriteriniai vertinimo metodai. Pasiūlyta daugiapakopė kūrybiškumą skatinančių veiksnių vertinimo sistema, sudaranti prielaidas identifikuoti (reikšmingumo nustatymo metodu) bei objektyviau juos įvertinti, formuoti siūlymus skatinti kūrybiškumąIn a constantly changing environment, factors influencing creativity and approaches to evaluating them, considered controversial in the scientific literature and in practice, are also experiencing changes. Different authors evaluate and interpret factors affecting creativity differently. Consequently, the problem how to identify and evaluate which of the approaches fully reflects the situation arises. The present article deals with these problems by combining the approaches of different authors from the aspects of identification and evaluation of factors affecting creativity. The aim of the article is to develop an evaluation system for factors affecting creativity in the Lithuanian Armed Forces. In an attempt to identify and evaluate factors affecting creativity, expert and multicriteria methods for evaluation were applied. A multi-level system for the evaluation of factors affecting creativity, that creates preconditions favourable for the identification of factors affecting creativity (by means of the method of determination of the significance of criteria), more objective evaluation of factors affecting creativity and development of suggestions for the stimulation of creativity, was suggeste
