In this paper, the authors discuss knowledge management, with a focus on knowledge sharing. Knowledge sharing is dependent on trust and cooperation, which are elements of organizational culture. One specific aspect of organizational culture is of particular interest for knowledge sharing. This aspect consists of values, beliefs and atmosphere that characterize common mental space accepted by knowledge workers which affect behavior and readiness to share knowledge. This aspect of organizational culture is called collaborative climate and can be described as the 'permeability' of the human infrastructure for knowledge sharing. Collaborative climate in an organization can be considered as an environment that provides support to knowledge workers to create new knowledge that will be translated into a value, which will become competitive advantage of an organization. A questionnaire for assessing two dimensions of the collaborative climate: Organizational Culture and Employee Attitude was used as an instrument in this research. The main research questions in this paper are: 1) Is there a statistically significant difference between attitudes towards collaborative climate of managers and employees? 2) Is there a statistically significant difference between attitudes towards collaborative climate in capital intensive and knowledge intensive organizations? Research hypotheses emerged from the main research questions. The survey was conducted in order to answer research questions. Data collection was carried out in 2016 throughout the territory of the Republic of Serbia. The sample in this research consisted of 114 managers from 78 randomly selected SMEs from the database of the National Agency for Regional Development. Afterwards, 647 employees were surveyed from those same companies, and in total 761 valid responses were collected. Principal component analysis was applied to the data. In order to check for statistically significant differences, factor scores were tested using Leven's homogeneity test of variance and t-test. Data analysis indicated the existence of statistically significant differences between employee and managers attitudes in their assessment of collaborative climate in capital intensive and knowledge intensive organizations.

Sustainable development is development that meets the needs of the present, without compromising the ability of future generations to meet their own needs. Sustainability indicators are based on the attempt to measure or determine the path of development of the economy in two directions: sustaining human wellbeing, or preserving the capacity to provide wellbeing. The research has been conducted to assess sustainability in the Southeast Europe, represented with a group of 10 countries with the 15 multi-metric indicators. A cluster analysis was performed on the set of indices to check the formation of distinctive clusters. Albania, Bosnia and Herzegovina, Macedonia, Montenegro and Serbia constitute first cluster, proving small differences among data. Second cluster consists of Bulgaria, Croatia and Romania, while last cluster consists of only Greece and Slovenia.

This article attempts to provide a model of key factors of knowledge infrastructure capability in SMEs in a transitional socio-economic environment from the perspective of knowledge management capability. Through the analysis of survey collected from 760 senior executives and employees from 86 SMEs in Republic of Serbia this research empirically models and evaluates the knowledge infrastructure capability. We also analyze whether the level of development of the knowledge infrastructure depends on the type of the industry SMEs belong to (knowledge or capital intensive). The results provide a basis for understanding the competitive position of SMEs as they start to undertake knowledge management activities.

The most influential trend, which has emerged as a result of the development of information and communication technologies, is business over the internet. Users of internet, and especially mobile internet, are mostly young people from 20+ to 30+ years of age. Marketing experts and researchers call these new users: 'Generation Y', 'Millennials', or 'Net generation'. This study analyzes consumer's attitude towards four constructs: perception of mobile internet ubiquity (time and spatial flexibility); use of internet - instant gratification; use of internet - product variety; and use of internet - riskiness. Research hypotheses were tested by analyzing data collected from a sample of 521 respondents from Serbia. Statistically significant differences according to age, gender, and education level of respondents were found. Considering the nature of the internet that allows reaching customers all over the world a better understanding of the attitudes of young internet users from Serbia.
