One of such tools refers to acquisitions through which companies can profit from synergic effects, reduce operating cost and tax expenses, and improve their market position. This paper is aimed at examining the effect of cross-border acquisitions made by Slovak companies in order to improve their performance. Authors applied the method of simultaneous equation model to examine this relation. The result confirmed the hypothesis that cross-border acquisitions positively influence a company performance.展开更多

It is provided with multiple functions, such as laser scanning information management for goaf, cloud data de-noising optimization, construction, display and operation of three-dimensional model, model editing, profile generation, calculation of goaf volume and roof area, Boolean calculation among models and interaction with the third party soft ware. Concerning this system with a concise interface, plentiful data input/output interfaces, it is featured with high integration, simple and convenient operations of applications. According to practice, in addition to being well-adapted, this system is favorably reliable and stable.展开更多

Prototypicality has its effects in acquisition of second foreign language vocabulary. The author hypothesizes that focal member words and basic level words are acquired earlier than non-focal member words and words on other levels of lexical hierarchies when prototypes of the target language correspond to those of the mother tongue in the same semantic categories. The results of a vocabulary test on beginner, intermediate and advanced learners of English as foreign language confirm the hypothesis. The paper concludes that learning a second foreign language means, to an extent, learning to categorize the worm in a different way, and prototypic effects should be given due attention in vocabulary instruction.展开更多
