The Reduction of Economic Dualism of Mazowieckie Voivodeship in 2007-2015 Using Regional Operation Programme for the Mazowieckie Voivodeship 2007-2013.The existence of social and economic dualism is widely discussed in numerous regions of Poland and Europe. This results from the natural structure of a region, which usually consists of one or two growth centres and peripheral areas. It leads to the emergence of inequalities, which cause a political pressure to redistribute income in order to ensure sustainable development. This discussion is particularly important in the Mazovian Voivodeship. Thus, the purpose of this study is to develop the existing findings concerning the social and economic dualism of the region. The main aim specified in the Voivodeship Development Strategy is to eliminate spatial inequalities. This paper is an attempt to broaden the knowledge on reducing the dualism in the voivodeship resulting from the implementation of the Regional Operational Programme for the Mazovian Voivodeship 2007-2013, which was one of the most crucial development tools. The analysis was conducted in terms of territory, sectors and the labour market.

The purpose of this paper is to explore the issue of the criteria of project success and the complexity of the subject in the context of environmental and nature conservation projects financed by European Union. The article presents various definitions of project success The article deals with definition and evaluation process of the project success as well as specific conditions of EU project management. Thematic evolution and trends in defining project success are presented through systematic review of literature on project management. The first part of the article focus on reviewing different approaches to the subject of criteria of project success, which is the crucial part of the proces. It is impossible to determine critical success factors (CSF) without deciding on the criteria of the project success. Project success definition is an important and complex project management issue. The success of the projects was considered for the last 50 years in a various ways and by different project management scholars. There is a consensus about the importance of this aspect for the project management practice. However, the project management in the context of EU-funded projects is still subject of further research, as this issue was not yet properly analyzed. The article presents the specific of the environmental and nature conservation EU-funded project judgement proces. The procedures and the scope of the formal and substantive assesment which is the part of selection procedure were described. The paper presents also how formal and substantive assesment criteria correspond with success criteria definitions created so far by the researchers. Moreover, the article analyses how existing asssesment criteria, precisely defined in EU programmes documentation and procedures, can be treated as EU project success criteria. The article presents also the most important challenges and issues in determining the set of success criteria based on assesment criteria set for regional operational programmes and Operational Programme Infrastructure and Environment for 2014–2020 programming period.
