Abstract

Projects of common interest are projects serving the implementation of priority corridors and areas of energy infrastructure, mainly trans-European electricity, gas and oil transmission networks in order to reduce the European Union’s energy dependence. They also help strengthen the energy security of individual countries, including Poland. The article aims at reviewing projects and assessing an impact on domestic markets in the context of the challenges of the fuel and energy sector in Poland. The article is an analytical study, in the “desk research” formula. Research methods used during the elaboration of the research include the analysis of national and EU strategic documents and the subject matter of energy security. In order to evaluate the impact of the implementation of projects of common interest on a variety of supplies of a member country (Poland), an exemplary assessment of the diversification status is presented using Hirschman-Herfindahl concentration index for gas supplies.

Abstract

The research focuses on the rental housing market in Riga and reveals that among factors that affect the rent level in neighbourhoods of Riga the most are distance from the city centre, neighbourhood safety, quality of housing and transport infrastructure, access to shopping malls, and employment opportunities. The aim of the research is to analyse the housing market in Riga, by putting a special focus on price determinants and lesson keys of Helsinki. Quantitative and qualitative research methods are used in the paper with the biggest contribution being extraction and analysis of data about more than 1800 rental apartments in Riga from the largest Latvian online real estate advertisement platform. Quantitative analysis is based on investigating relationships between average rent levels in different neighbourhoods of Riga and index values of 23 urban environment factors. In addition, the rental housing market in Helsinki is researched, emphasising few guidelines for rental housing market improvements in Riga, such as introducing government subsidies.

Abstract

This paper provides a description of the community governance paradigm shifts in China over the past 4 decades. By taking a historical review of Chinese tradition in community governance, a brief history of the transformation of property rights in the former Soviet Bloc, plus a theoretical analysis from the perspective of social physics, this study clarifies the inherent logic for the community governance evolution across China. The influence that ancient dynasties, up to 1949, exerted upon the modern community governance has been large, which has formed certain social governance inertia. However, there have emerged many new forms of power among which the homeowners are the strongest group to demand more autonomy. By using a social physics framework, this article sheds light on the ongoing tension between the traditional inertia and the emerging trend of autonomy in real estate. Furthermore, the logic could be employed for predicting the future community governance style in China.

Abstract

Of recent, the need to increase the performance of services installations in buildings has been a major point of interest amongst construction professionals through the consideration of commissioning practices required to be adopted during execution of building projects. The aim of the study is to investigate awareness of building professionals on the adoption of building commissioning practices in the installation and use of building services equipment. The study therefore examines the characteristics of building commissioning practices, examines the level of awareness and adoption of building commissioning practices amongst construction professionals in Lagos State, Nigeria, as well as investigates the factors influencing their adoption. A survey method of research was employed with questionnaire administered on construction professionals available on the list of firms of the Federation of Construction Industry (FOCI) registered with the Lagos State Government. The data collected were analysed with the use of statistical tools, such as frequency distribution, mean item score, analysis of variance and factor analysis. The study shows that amongst the characteristics of building commissioning practices, lighting services have the highest level of engagement with a mean score of 4.45, heating, ventilation and air-conditioning 4.15 while vertical transporting services have a mean score of 3.82. A significant proportion of the respondents are aware of building commissioning practices through different professional training courses and practices. The study also shows that there is relationship between the level of awareness and adoption of building commissioning practices at 95 % confidence level. The indicators in group one are found through the factor analysis to be contributing mostly to the adoption of building commissioning practices by the respondents. The study concludes that with the existing level of its awareness in the study area, efforts should be made by stakeholders to entrench building commissioning practices provisions in the country’s institutional framework/regulatory code, which covers the installation and use of service items in building stock so as to further deepen their adoption in order to enhance performance and comfort of building projects.

Abstract

The construction industry is one of the most important activities that contributes towards the economic growth of any nation. However, the sector has been experiencing problems of cost and time overruns, particularly the problems are significant for the lowest-bid awarded construction projects in the developing countries where inappropriate planning is reported to be one of the major causes. Thus, the paper aims at developing an integrated scheduling approach for construction projects during the planning phase from a project owner’s perspective. The proposed approach integrates cost estimation and schedule in light of practical activity precedence and mathematical cost optimization using different project commencement dates. The study has shown that cost and time optimization model could yield impractical results unless double precedence relations (start-to-start plus finish-to-finish) are imposed between some activities such as trench excavation and pipe laying. It has also demonstrated that the cost and time budgeted during the planning phase would substantially deviate from actual if the planned construction start date slips from the plan, particularly for short period projects. The proposed approach demonstrated in the paper can sufficiently allow planning engineers to develop a comprehensive construction schedule so that the cost and time overruns in the lowest-bid awarded construction projects can be reduced. The paper provides empirical insights into how a robust construction schedule is developed from an owner’s perspective. Cost-time optimization and risk analysis results obtained from manual computation might reduce the reasonable accuracy of the desired cost and schedule integration unless each activity is assigned its own calendar.

Abstract

Construction sector has an important place in Turkey’s economy. Real estate sales for the sector are increasing in parallel. However, the purchase cost is also important for those who are willing to buy a real estate. In the acquisition of real estate, factors such as size, location and age of the house are taken into consideration. The aim of the article is to conduct research on factors affecting real estate values by data mining. In this study, the most important variables that determine the value of the real estate have been investigated by data mining methods. The research has been carried out in Karabük and the variables determined according to the opinions of real estate experts. As classification methods, CHAID and C&RT algorithms have been used. It has been evaluated that both algorithm estimation results can be used. Within the framework of the study, the variables that have the most impact on the unit price have been determined, such as the size of the real estate, the distance to the city centre, the popularity, and the age of the building. The use of advanced technologies, such as statistical modelling and machine learning in real estate valuation and automatic value estimation, is of importance in determining the real value of the real estate.

Abstract

Widespread usage of the internet and computers have facilitated a number of human resource management activities such as compensation management, performance management, vocational training and other personnel management affairs across various enterprises. It is known that the employment of a qualified labour force becomes increasingly difficult due to increasing competition conditions. Therefore, it is important to ensure that the right person is recruited for the enterprise and that he/she is attached to his/her employer. Thanks to information technologies, the recruitment process can be implemented more quickly and effectively. The present study aims at determining whether the employer-employee has a sense of trust; whether employee’s performance, disciplinary action, reporting status and significant inconvenience status are taken into account by an enterprise in the iron and steel industry. Logistic regression method is used as an analysis method. The effects of the demographic variables on the dependent variables are also determined. Considering the results obtained, it is observed that the loyalty of the employees to the employer is not very strong, but at the level of improvement, the employees do not consider working at the company for many years.

Abstract

The forthcoming transfer of St. Isaac’s Cathedral in St. Petersburg being a UNESCO World Heritage Site to the Russian Orthodox Church ignites a heated debate within the Russian society. The cathedral being part of the State Museum Complex stands out as a pearl of the world’s iconic architecture. Furthermore, it is the second most visited museum after the Hermitage, boasts an outstanding exhibition potential, and it regularly hosts church services and ritual events. Museum collections exceed twenty-four thousand items of storage, and they continue to be replenished with found rarities and newly restored objects with the status of a relic to be protected. The aim of the article is to measure the value of the assets of the monument building, assessing the insured value of the object. Uncertainty of the future use of the disputed object, however, allows us to consider the calculation capabilities and methodical tools of valuation activities to measure the market and insurance value of such a real estate object and land plot, for example, in order to practice damage compensation and transfer the object from the balance sheet of one owner to balance of another owner. The latter circumstance determines the main discourse of this study. The present article is devoted to questions of an expert estimation of the insured value of the object of research in the form of St. Isaac’s Cathedral. The article is a continuation of a series of previously published works by the author.

Abstract

The paper aims at providing insight into the effectiveness of Latvian special economic zones (SEZ) as a tool to attract foreign direct investment (FDI). The goal is accomplished through the statistical analysis of relevant data and the comparison with international examples to establish a point of reference. Countries of comparison are chosen by merit, in the form of widely acknowledged success stories regarding SEZ policy, and relative statistical similarity. The wider the pool of examples, the more conclusions can be drawn about the effectiveness of SEZ in various metrics. Based on the results, Latvian special economic zones have significantly underperformed when compared to every single example on the list. Research has been approbated in the Riga Technical University 58th International Scientific Conference “Scientific Conference on Economics and Entrepreneurship” (SCEE’2017).

Abstract

Due to increase in growth of real estate development, green certification systems are essential to ensure the well-being of society and environment. Green Building Councils are the main drivers that influence many factors related to development of green buildings, which includes certification, education, conference and other aspects. The aim of the article is to analyse the tendencies of the development of green buildings in the Scandinavian and Baltic countries by analysing the Green Building Councils of the Baltic and Scandinavian Countries, and the number of certified green buildings in both regions. The literature review, comparative analysis, document analysis, and logical access methods have been used in the research. The countries are different from each other and their current and future priorities differ from each other as well. In the research process, it is important to lay some light on the several funds acquired by the regional Green Building Councils and their usage. The research results show that all the countries are working towards the development of green buildings but some countries perform better in the number of certified green buildings. The research results, including the number of green certified buildings, future plans of Green Building Councils, recommendations for future market analysis of green buildings, have already been approbated at the 59th International Scientific Conference of Riga Technical University “SCEE 2018” (Scientific Conference on Economics and Entrepreneurship) in Riga, Latvia.
