Despite the growing utility and prevalence of social entrepreneurship, an accepted definition remains elusive and infeasible. Yet, it is imperative that the principles guiding social entrepreneurship are identified so that common ground is established to facilitate future research. On the basis of a systematic literature review, this conceptual paper proposes a theoretical framework outlining social entrepreneurship as a three-dimensional framework as a function of continua of “social” and “business” logics, “beneficial” and “detrimental” social change logics, and “innovation” and “mundane” logics. The framework accommodates the fuzziness and ambiguity associated with social entrepreneurship whilst remaining a workable, identifiable construct. By accounting for the shifting logics practiced by social entrepreneurship that both influence and are influenced by the organizational environment, this framework provides an exit strategy for the definitional elusiveness of social entrepreneurship. The resultant structures and functions of social entrepreneurship are shaped by these constraints as reflected by the fluidity and flexibility endorsed by the framework. Four avenues for future research regarding social entrepreneurship are recommended on the basis of the framework proposed in this article.

Three Dimensional Virtual Worlds (3DVW) have been substantially adopted in educational and pedagogical fields worldwide. The current study conducted a systematic literature review of the published research relevant to the application of 3DVWs in higher education. A literature search was performed in eight high-ranking databases, and following scrutiny according to inclusion criteria, 164 papers were selected for review. The systematic literature review process was summarized, reviews undertaken by the authors, and results about the applicability of 3DVWs in higher education were extracted. A wide variety of application areas for the 3DVWs in higher education were found, and were classified into five main categories. Various 3DVW platforms and virtual environments used for educational goals were also identified. The results revealed Second Life as the most popular 3DVW platform in higher education. This study also found that by using 3DVW technology a wide range of virtual environments and virtual tools have been designed and applied in teaching and learning for higher education.

In Augmented Reality systems, virtual objects are combined with real objects, both three dimensional, interactively and at run-time. In an ideal scenario, the user has the feeling that real and virtual objects coexist in the same space and is unable to differentiate the types of objects from each other. To achieve this goal, research on rendering techniques have been conducted in recent years. In this paper, we present a Systematic Literature Review aiming to identify the main characteristics concerning photorealism in Mixed and Augmented Reality systems to find research opportunities that can be further exploited or optimized. The objective is to verify if exists a definition of photorealism in Mixed and Augmented Reality. We present a theoreticalfundamental over the most used methods concerning realism in Computer Graphics. Also, we want to identify the most used methods and tools to enable photorealism in Mixed and Augmented Reality systems.

New technological developments determine the course of the construction industry. Three-dimensional (3D) printer technology has become one of the technologies that determine the production logic of the 21st century. The concept of Industry 4.0 gained importance in the construction industry with a 3D printer. In this study, a systematic literature review was performed. The publications related to the 3D printer have been examined within the scope of civil engineering implementations. The 3D printer researches associated with BIM, Industry 4.0, NASA, additive manufacturing, and point cloud technology subjects was reviewed through an intensive systematic literature review. As a result of the study, it has been understood that the studies in the field of civil engineering were insufficient compared to manufacturing industry. For this reason, the number of researches on 3D printer applications should increase in construction industry.
