Energy policies are vital tools used by countries to regulate economic and social development as well as guarantee national security. To address the problems of fragmented policy objectives, conflicting tools, and overlapping initiatives, the internal logic and evolutionary trends of energy policies must be explored using the policy content. This study uses 38,277 energy policies as a database and summarizes the four energy policy objectives: clean, low-carbon, safe, and efficient. Using the TextCNN model to classify and deconstruct policies, the LDA + Word2vec theme conceptualization and similarity calculations were compared with the EISMD evolution framework to determine the energy policy theme evolution path. Results indicate that the density of energy policies has increased. Policies have become more comprehensive, barriers between objectives have gradually been broken, and low-carbon objectives have been strengthened. The evolution types are more diversified, evolution paths are more complicated, and the evolution types are often related to technology, industry, and market maturity. Traditional energy themes evolve through inheritance and merger; emerging technology and industry themes evolve through innovation, inheritance, and splitting. Moreover, this study provides a replicable analytical framework for the study of policy evolution in other sectors and evidence for optimizing energy policy design

Reduction of virgin materials use by the construction industry has high priority and can be achieved by reusing structural and non-structural building components from existing buildings. The high value reuse of building components has not been adopted yet on a large scale because of several reasons, one of them being poor building information management. Therefore, this paper investigates the role of building information modeling (BIM) for that purpose. Based on a review of literature, a preliminary decision making framework is proposed that will be elaborated in the nearby future. The literature review revealed that the use of BIM in combination with other digital technologies looks promising, but that additional research is needed into the governance related aspects of BIM. © 2017 Taylor & Francis Group, London.

The term escapism tends to be used in game research without providing any extensive definition of what it means or acknowledging its composite nature. In this paper, the authors question the possible conceptualizations of escapism and the extent to which gamers identify with them. Beginning with a theoretical deconstruction of escapism, the authors developed a framework that they applied in an empirical study with three focus groups. Respondents in these groups completed a survey and participated in a group discussion. The resulting data allowed the identification of eight different discourses of escapism in the context of playing multiplayer computer games. In addition, the study showed that citing escapism as a reason for playing games elicits debate and emotional responses. Given the existence of multiple interpretations and connotations, this paper concludes that escapism is problematic for use in surveys, interviews, and other research techniques.
