Predicting M&A targets using news sentiment and topic detection
This paper uses news sentiment and topics to discuss the challenges and opportunities of predicting mergers and acquisition (M&A) targets. We explore the effect of investor sentiment on identifying M&As targets and how company-specific news articles can be used as a source of sentiment and topics to obtain richer information on various corporate events. We propose a framework incorporating news sentiment and topics into the M&A target prediction …

Research trends in the application of big data in smart cities—A literature review
In this study, we review articles published in academic journals. in the last 5 years at the intersection of big data and the smart city context. Based on a dataset of 192 articles, we use content analysis to identify recent trends and future research directions. The most influential research areas identified include using big data analytics, electric vehicle integration, and citizen‐centric big data, while the most recent research area that emer…

Competitiveness and economic profit analysis of Kazakhstan’s poultry companies
Measuring competitiveness in entral Asian post-socialist countries is problematic as many well-known metrics systems fail to warn about bankruptcy risks sufficiently early or at all. With 2013-2017 data, we have compared data on the selected poultry sector companies operating in Kazakhstan to analyze their competitiveness, while financial analysis metrics provided us with the financial performance data. In particular, we have analyzed two publicl…
Interactions among energy consumption, CO 2 , and economic development in European Union countries
Sustainable development has become a major problem in European Union (EU) countries. This has prompted many researchers to examine a broad range of interactions among sustainable development indicators. This study uses the variance decomposition and cointegration approach to assess the causal relationship among energy consumption, CO 2 emissions, and economic development (gross domestic product [ GDP ], foreign direct investment [ FDI ], net expo…
Snow avalanche hazard of the Krkonoše National Park, Czech Republic
This paper presents a snow avalanche hazard map of the most avalanche-prone mountain range in the Czech Republic, the Krkonoše Mountains. The map was prepared using historical records of 1132 avalanches which occurred over the last 54 years and state-of-the-art modelling of avalanche propagation and the spatial distribution of potential avalanche source areas. The map provides not only reliable and easy to understand information for the Mountain …
Comprehensive assessment of firm financial performance using financial ratios and linguistic analysis of annual reports
Indicators of financial performance, especially financial ratio analysis, have become important financial decision-support information used by firm management and other stakeholders to assess financial stability and growth potential. However, additional information may be hidden in management communication. The article deals with the analysis of the annual reports of U.S. firms from both points of view, a financial one based on a set of financial…

Economic Analysis of the Impact of Changing Production Conditions on Wheat Productivity Level
Production conditions of crop growth have a considerable effect on the labour productivity rate because of the changes in the level of yield performance. In this paper the calculations have been made to estimate the correlation between production, including hydrothermal and grain yield indices in the Zelinogradsky district of the Akmolinskaya oblast (province) of Kazakhstan. As a result of estimation process, only the most significant factors hav…
