Neighbourhood Ties and Migrant Networks: The Case of Circular Ukrainian Migrants in Warsaw, Poland

100%

Toruńczyk-Ruiz S.

nr 1

41-62

The paper deals with the importance of neighbourhood ties in the social networks of circular migrants. While existing research shows that social networks constitute a crucial element in the process of circular migration, not much is known about the extent to which these networks are territorialised. The paper discusses this issue by analysing the case of Ukrainian migrants in Warsaw and its suburbs, who are close to the receiving society in both cultural and geographic terms and thus make this group a unique case compared to immigrants travelling to Europe from more distant places. The analyses are based on data collected in a survey on Ukrainian migrants carried out in 2010 by the Centre of Migration Research, University of Warsaw, with the help of Respondent Driven Sampling (RDS). The studied sample consists of 342 respondents with different duration of migration from Ukraine to Poland. The paper argues that neighbourhood ties do not play an important role in the social capital and mobility patterns of Ukrainian circular migrants. The social relations of migrants are formed through ethnic and kinship ties, which are not related to a specific local area. The analyses also confirm earlier findings which show that Ukrainian migrants do not tend to concentrate spatially in the Warsaw metropolitan area, but which do point to the existence of small ethnic clusters. However, these seem to be determined by structural factors such as the availability of flats rather than individual preferences to live close to co-ethnics, which altogether suggests that there is a limited potential for local community formation among Ukrainian migrants.

The paper presents models, parameters and assumptions concerning Satellite Laser Ranging (SLR) and Global Navigation Satellite System (GNSS) data processing, which will be conducted in the frame of a project concerning comparison of the site coordinates determined using these two techniques. The analysis will be performed by two research units: the Space Research Center (Polish Academy of Science) and the Center of Applied Geomatics (Military University of Technology) and will take into account the data from all global stations adopting SLR and GNSS techniques that were operating in the same time (from 1996 to 2011). The main goal is to obtain exact coordinates and their changes in time (velocities) on the basis of both techniques and to compare the results. The stations’ coordinates will be determined for the common reference epoch - for the first day of each month. According to the recommendations of the Global Geodetic Observing System (GGOS), the same models and parameters from IERS Conventions 2010 will be used in both processing strategies (if possible). Monthly orbital arcs for laser observations will be created on the basis of solutions from several SLR sites providing best quality results and the highest number of observations. For GNSS coordinates determination of about 100 sites belonging to International GNSS Service (IGS) will be selected: 30 with local ties to SLR sites and others chosen on the basis of their localization and quality of time series.

Although a open-list PR system guarantees the voter the possibility of nominating a specific candidate from the list, which, according to voters, should represent his political option, it is often said that voters do not exercise that power, and that for the election results the most important is candidate’s ballot positionHowever, we know that the personal votes have a real impact on the electoral success. The question is what prompts voters to vote for a particular candidateThe purpose of this article is to analyze the results of the elections to the Polish Sejm from 2015 in terms of the ballot position effect, the intervention effect of the personal votes on the electoral success and effect of one of the determinants of the individual candidate’s success — locality/local ties of candidate.
