Green construction ecosystem was studied. The author analyses the system of construction, and proposed the system of green construction based on ecology theory which was included subsystem of the condition, process and objective on the ecosystem in order to lay the foundation for system evaluation. The text analyses elements of green construction system, which would help to improve the competit...

The ongoing process of liberalization, as well as the intensive technological breakthrough have a great impact either on the macroeconomic policy creators, or the dissimilarity of conventional approach to found a strategy of a certain company. Bearing in mind the very notation, core characteristics of the concept of competitiveness are needed to be explored, but also the necessity to establish ...

The European Union (EU) can be regarded as one economic region and this way its competitiveness can be defined and examined. However, there are huge tensions within the European region that raise questions about whether there exists a European economic region and thus “European competitiveness” at all. Unlike some of its largest competitors, Europe still has not overcome the financial and econo...

innovation and sustainable development have been considered fundamental elements in the competitive positioning of companies. the synergies between both concepts, known as eco-innovation, must be considered when designing company policies. the aim of this paper is to analyse which moderating factors determine how innovative companies perform when implementing a sustainable proactive approach. w...

The focus of this article is to clarify the meaning of international competitiveness at the country level within in the context of Porter’s (1990a) thesis that countries, like companies, compete in international markets for their fair share of the world markets. At a country level, there are two schools of thought on country competitiveness: the economic school, which rejects Porter’s notion of...

In the current era, competition among countries and regions is in fact among cities. Thus, how to measure urban competitiveness precisely is a basic and important question. The two main approaches to this are comprehensive evaluation based on a set of indicators and network analysis based on inter-city relations. However, both have shortcomings.

Explanations for the evolution of polyandry often center on the idea that females garner genetic benefits for their offspring by mating multiply. Furthermore, postcopulatory processes are thought to be fundamental to enabling polyandrous females to screen for genetic quality. Much attention has focused on the potential for polyandrous females to accrue such benefits via a sexy- or good-sperm me...

We consider 2-server algorithms with time complexity O(1) per each request. We show that the previously known algorithm BALANCE2 has competitiveness constant not better than 6, and present another algorithm whose competitiveness constant is 4.
