Proposed in the United States of America 1970s, term “public history” is now used various parts world. The internationalization field public history raises questions about its definition, practices, and theories. Based on sometimes long-established reflects new approaches to audiences, collaboration authority production. article distinguishes analyses different phases 1990s, 2010s argues for a ...

This paper highlights the not-so-obvious but compelling reasons why the same supportive audiences that can help performers attain their highest potential also may increase performers' risk of choking under pressure. Drawing primarily from social psychology research and theory, we conclude that audience support magnifies performance pressure and induces performers to avoid failure rather than se...

The handling of mistakes in the mathematics classroom is an area in which only little research is done so far. In mathematics education there are, in fact, several investigations about students’ mistakes from a diagnostic perspective, but hardly any studies on the question how teachers react in concrete mathematics lessons. In this article theoretical aspects and results of different video stud...

Prestressed concrete (PSC) is one of the most reliable, durable and widely used construction materials, which overcomes the weakness of concrete in tension by the introduction of a prestress force. Smart strands enabling measurement of the prestress force have recently been developed to maintain PSC structures throughout their lifetime. However, the smart strand cannot give a representative ind...

User behavior in online social media is not static, it evolves through the years. In Twitter, we have witnessed a maturation of its platform and its users due to endogenous and exogenous reasons. While the research using Twitter data has expanded rapidly, little work has studied the change/evolution in the Twitter ecosystem itself. In this paper, we use a taxonomy of the types of tweets posted ...

To comply with recent international trends and initiatives, and in order to help achieve sustainable development, Korea has established a greenhouse gas (GHG) emission reduction target of 37% (851 million tons) of the business as usual (BAU) rate by 2030. Regarding environmentally-oriented standards such as the IGCC (International Green Construction Code), there are also rising demands for the ...

this paper presents theoretical and numerical state-of-the-art information in the field of hygro-thermo-mechanical deformation simulation in structural concrete. the aspects discussed include coupled hygro-thermo-mechanical performance of porous materials including concrete, multi-scale simulation of concrete properties especially the volumetric and structural deformation performance, and the m...

We aim to produce a range of educational materials to teach robotics to a variety of audiences using the LEGO Mindstorms Robotics Invention SystemTM. We briefly review the programming environments currently available and consider their appropriateness for our candidate audiences. There is the usual trade-off between ease of use and power. It is suggested that no single programming environment i...

todays applying concrete structures is more usual than other structures which are used in buildings as in most of the world’s countries the application ratio of concrete to steel has increased from 10 to 1. sometimes these structures require strengthening vulnerable members because of deficiency in their loading system in usual and critical conditions. there are different methods for strengthen...
