This study investigates the political engagement of Vietnamese immigrants in Poland on social media. It employs the typology of online political participation as a theoretical framework to determine the pattern of online in-volvement in the political sphere staged by the migrant group. Through analysing materials relating to political discussions created daily on an online community of the Polish Vietnamese, collected by doing netnography, this study shows that the political activism on social media of Vietnamese immigrants in Poland exists and varies. Vietnamese-migrant users discuss homeland politics and express views about political issues in the host country as well as other countries by creating non-mobilising posts (Information and Diffusion), while being inclined to produce posts with calls for action (Instruction and Promotion) to criticise social injustice and mobilise equality. This study also found a growing critical attitude towards homeland politics among Vietnamese-origin individu-als in the country. The findings have practical implications for associations and state actors in both the host and home countries to account for the evolvement of the migrant community.

Irrigation and hydropower are among the most important sectors in the construction industry that propel the economic needs of a developing country like Vietnam. The construction of these projects often suffers from severe delays, leading to financial losses and other negative impacts on the economy. This paper aims to determine delay factors in the construction of these projects. Among many, 39 most important candidates of delay causes were identified from the literature review. Further surveys on project participants were conducted for the severity of these causes. An exploratory factor analysis was utilized to identify latent factors that cause delays in construction projects. The analysis result categorized a few groups of factors such as abnormal factors on the construction site (e.g., labor accidents, hydrology, water flow, extreme weather) and technical factors related to the construction contractor (e.g., unsuitable schedule, outdated construction technology, unprofessional workers) that have the greatest impact on the delay in construction of irrigation and hydropower projects in Vietnam. These findings contribute to the body of knowledge of project management and risk management, hence an improvement in the efficiency of the project sectors’ performance.
