Project manager’s skills which are the competencies required for successful completion of the project play an important role in the construction industry, therefore acquiring these skills is significant for project success. However, indigenous construction firms compete with their multinational counterparts for the available skilled workforce. The study, therefore, investigates the level of project managers’ skills acquisition in indigenous and multinational construction firms in Lagos State, Nigeria. The study adopted cross-sectional survey research and data were collected using a structured questionnaire. One hundred and thirty-three questionnaires (106 indigenous and 27 multinational) were administered to project managers and 106 retrieved and valid for analysis representing 73% response rate. The techniques for analysing the data are mean score and t-test. The study revealed that the most important skill type as perceived by project managers is a technical skill and there is no significant difference in the level of skill acquisition by project managers in indigenous and multinational construction firms. Hence, the study concludes that the categorisation of construction firms has no effect on the level of skills acquisition by project managers; therefore, it plays no role in project managers’ skills acquisition. Project managers should strive towards developing themselves through training for improved performance and for successful completion of construction projects.

This paper focus on description of railway safety system radioblock and its application. Content of the paper describes usefulness of this system on those railway lines, which have been operated according to norm about simplified supervision of railway operation. Theoretical basis of the research is proved by case study on the railway line Číčenice – Volary (Czechia). This railway line is the only railway line with this safety system nowadays. Application of these issues is evaluated from safety and technology point of view. There are some suggestions for other railway lines, which are suitable for radioblock railway safety system.
Climate change becomes a widely acknowledged and inevitable global challenge of 21st century. For developing countries like Ethiopia, it intensifies existing challenges of ensuring sustainable development. This study examined factors affecting climate change adaptation and mitigation strategies by taking in Protection Motivation Theory. The study draws on mixed research approach in order to assess the subjective understanding about climate change threats and identify the factors determining responses to climate change. While qualitative data were collected through focus group discussions and interviews, quantitative information was collected using semi structured survey from 296 randomly selected farmers from different agro-ecologies. Qualitative data was dominantly analyzed using content analysis while descriptive and inferential statistics were applied to analyze quantitative data. Almost all respondents (97%) perceived that climate change is occurring and threatening their wellbeing. Dwindling precipitation, increasing temperature and occurrence of human and animal disease were perceived to represent climate change. From nationally initiated strategies, farmers were found to largely practice soil and water conservation and agricultural intensification, which they perceived less costly and compatible to their level of expertise. The result of binary logistic regression revealed that perceived severity of climate change, perceived susceptibility to climate change threat, perceived own ability to respond, response efficacy and cost of practices predicted farmers motivation to practice climate change adaptation and mitigation strategies. Thus, building resilient system should go beyond sensitizing climate response mechanisms. Rural development and climate change adaptation policies should focus on human capital development and economic empowerment which would enable farmers pursue context specific adaptation and mitigation strategies thereby maintain sustainable livelihood.

The paper deals with the analysis of the development of mobile devices and current trends in their use and development. The relevance of the article is in its linking history and present. The article points to milestones in historical development and future trends and development of mobile devices. Today, mobile devices affect all areas of human life, whether private or business. Mobile devices are now able to replace computers and laptops, so the user has the information they always have with them. The development of mobile devices inherently includes systems supporting their functioning, which the article also discusses.
The effectiveness of regional railway lines has been a much discussed theme recently mainly in case of lines which are not sufficient per the capacity requirements of carriers, or vice-versa, which are utilised only to a minimum extent. The article deals with the assessment of options how to utilise the railway line Hodonín - Holíč nad Moravou with respect to its inclusion into Revision of Transport Expenses document. Based on the analysis of present operation situation in that border crossing as well as on the analysis of passenger and freight railway transport operation various options of utilising the line have been investigated with respect to operation and economic options of individual alternatives.
This article approaches the topic of the emerging adulthood with young people in Romania, as well as the beginning of the first work experience. The main aim is to identify the factors of a successful transition from school to independent life. The article examines the social status and the issues the young people in Romania face with regard to the transition from education to employment. The data type longitudinal panel study refers to the cohort of young people born in 1994-1995, the generation which graduated from the 12th or 13th class in 2012. We answer the question „Which are the factors that determine the first work experience for Romanian young people and what does this look like?” Half of the young people have work experience - 50.1%, with 25.2% working at the time they filled in the questionnaires, two years after graduation. Employment is explained to an extent of 1% by gender and area of residence, 4% by factors of social exclusion and 1% by factors related to negative life events. All these factors explain the variance of 6% in the employment of young people. Linear regression analysis (hierarchical) showed that social inclusion factors have the greatest effect on employment, with 4% of employment variance explained by social exclusion factors, while the influence of the demographic variables, factors of social exclusion and factors related to negative life events explain 6% of the youth employment variance.
The success of higher education graduates’ transition to the labor market is analyzed in this paper. A series of representative factors which influence the success rate on the labor market were analyzed through an exhaustive case study among graduates from West University of Timisoara. The results show a high level of satisfaction amongst graduates, despite the high level (over 40%) of total incongruence (vertical and horizontal) between the degree’s field and the actual workplace. We can also assert that the graduates’ insertion in the labor market is a real success, since most of them are able to get a job in less than 6 months from graduation (58.5%), even more do so 12 months post-graduation (83.9%).
Transport and its major part of transport means is currently based on the internal combustion engine principle. For these engines, the primary energy source is oil, natural gas, coal, biomass and others. These primary energy sources and their processing in refineries and factories are used to produce products that are used to drive engines - fuels. From what energy sources these fuels will be produced and what technology will be used to process and produce them is also an important. This whole process must take the reduction of total emissions into account. Future fuels can be considered synthetically produced diesel or hydrogen, which can later significantly affect the decrease in emissions from their processing, production and subsequent combustion of these more environmentally friendly types of fuels. This article processes analyses and development of basic pollutants, total emissions and energy consumption in the Slovak Republic and the EU. In the second part there is an evaluation of the emissions trend development in transport in the EU and Slovakia.

Predictive modeling is the key fundamental method to study passengers’ behavior in transportation research. One of the limited studied topic is modeling of public transport usage frequency, which can be used to estimate present and future demand and users’ trend toward public transport services. The artificial intelligence and machine learning methods are promising to be better substitute to statistical techniques. No doubt, traditionally been used econometrics models are better for causal relationship studies among variables, but they made rigid assumptions and unable to recognize the pattern in data. This paper aims to build a predictive model to solve passengers’ classification, and public transport usage frequency using socio-demographic survey data. The supervised machine learning algorithm, K-Nearest Neighbor (KNN) applied to build a predictive model, which is the better machine learning method for dealing with small datasets, because of its ability of having less parameter tuning. Survey data has been used to train and validate the model performance, which is able to predict public transport usage frequency of future users of public transport. This model can practically be used by public transport agencies and relevant government organizations to predict the public transport demand for new commuters before introducing any new transportation projects.
