To engage in an effective corporate social responsibility (CSR) action, it is necessary to first recognise its impact on targeted buyers. This study surveyed respondents from Poland and Ukraine to analyse their perception of initiatives related to environmental protection and the effect of such initiatives on purchasing behaviour. The study demonstrated how consumers’ age, education level, or professional position influence their purchasing decisions and feedback on different kinds of CSR actions related to environmental protection. Of the five areas identified in the questionnaire (environmental protection, cooperation with the local community, corruption and bribery, labour and employment, and human rights), environmental protection was found to be the most important to consumers. These results may help in decision making regarding specific environmental CSR initiatives targeted at selected social groups living in this region of Europe.

Changes in the global economy observed in the last decade are, to a significant extent, the result of the globalization of markets and the liberalization of international service-oriented turnover. The progressive globalization changes the conditions for the operation for the business entities of an international character. These companies, adapting to new market conditions, are seeking solutions which would allow them to maintain their competitiveness. One of the tools that companies use to improve their competitiveness is offshoring (BPO). This is a process related to the transfer of the implementation of production and service processes to the territory of another country. Location choice in the BPO decisions has become an important strand of the international business literature with a number of scholars examining the influence of host country variables such as property rights, intellectual property protection, public trust in politicians, government factors and others. Poland is the Central and Eastern European leader in the sector of modern business services. This country has many business service centers with foreign capital, which employ thousands of employees. Additionally, employment in this sector is systematically growing by 20% each year. Poland's attractiveness on the map of offshoring investment projects results mainly from a very well qualified and cheap workforce. Offshoring Centers located here offer both BPO and KPO services.

Crowdsourcing in the public sector-a model of social participation This article is about the use of crowdsourcing in public sector. In many countries in the world, also in Poland, state authorities at various levels have sought effective ways to involve their citizens in public decision-making. The main objective of increasing civic engagement is to broadly promote trust in public authority activities and to build civil partnerships. The Polish experience in this area is not satisfactory and forces both practitioners and theorists to look for solutions that would achieve such goals. The author presents the model of key elements infl uencing the level of civic engagement.
