The purpose of this paper is to determine the development and knowledge flows of dye-sensitized solar cells (DSSCs) via the use of patent inventor database. Moreover, this study aims to explore patentees and inventors’ companies to help readers and practitioners to be able to understand the patentees, technology development and activities of knowledge flows from four countries. DSSCs, which are known as one of the key technologies of green energy, have been applied ever more widely to many different industries, and their use has quickly grown with a number of scientific publications and patent applications.
This paper was based on the US patent database collection of third-generation DSSCs in four typical countries such as USA, Japan, Germany and Taiwan to map the knowledge network of DSSC technology via the social network analysis method.
The knowledge network of 132 DSSC patents was explored. Among the four countries, Japan leads, with the main patent number being H01G009. This paper also indicates the knowledge flow situation of Japanese inventors of DSSCs. For example, patented inventors Wariishi and Koji (JP) served the Fuji Photo Film Co., Ltd. (JP) in 2002, and then in 2008, transferred to the Fuji Film Corporation (JP). This means that the knowledge of technology was transferred by people who moved to another company for a new job.
This study is based on US Patent and Trademark Office patent database to do exploration.
This study was expected to provide information for the industry, government and academia, so that they will understand the trajectory of the technology inventor, specialist cultivation and technology development in the DSSC industry.
This study provides useful information for the green energy industry, government and academia to understand the importance of the knowledge flows and future development of DSSC technology of the solar cell industry. Thereby, they can intensify industrial competence and innovation by externally collaborating in this field as well as to increase the industrial competence by reimbursing the funds from government and other research institutes.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

Most decision-making problems in construction are complex and difficult to solve, as they involve multiple criteria and multiple decision makers in addition to subjective uncertainties, imprecisions and vagueness surrounding the decision-making process. In many instances, the decision-making process is based on linguistic terms rather than numerical values. Hence, structured fuzzy consensus-reaching processes and fuzzy aggregation methods are instrumental in multi-criteria group decision-making (MCGDM) problems for capturing the point of view of a group of experts. This chapter outlines different fuzzy consensus-reaching processes and fuzzy aggregation methods. It presents the background of the basic theory and formulation of these processes and methods, as well as numerical examples that illustrate their theory and formulation. Application areas of fuzzy consensus reaching and fuzzy aggregation in the construction domain are identified, and an overview of previously developed frameworks for fuzzy consensus reaching and fuzzy aggregation is provided. Finally, areas for future work are presented that highlight emerging trends and the imminent needs of fuzzy consensus reaching and fuzzy aggregation in the construction domain.

Numerical results are reported for a dilute turbulent liquid‐solid flow in an axisymmetric sudden‐expansion pipe with an expansion ratio 2:1. The two‐phase flow has a mass‐loading ratio low enough for particle collision to be negligible. The numerical predictions for the dilute two‐phase flow are based on a hybrid Eulerian‐Lagrangian model. A nonlinear k‐ε model is used for the fluid flow to account for the turbulence anisotropy and an improved eddy‐interaction model is used for the particulate flow to account for the effects of turbulence anisotropy, turbulence inhomogeneity, particle drift, and particle inertia on particle dispersion. The effects of the coupling sources, the added mass, the lift force and the shear stress on two‐phase flow predictions are separately studied. The numerical predictions obtained with the improved and conventional particle dispersion models are compared with experimental measurements for the mean and fluctuating velocities at the different measured planes.

This research provides accounting-ethics authors and administrators with a benchmark for accounting-ethics research. While Bernardi and Bean (2010) considered publications in business-ethics and accounting’s top-40 journals this study considers research in eight accounting-ethics and public-interest journals, as well as, 34 business-ethics journals. We analyzed the contents of our 42 journals for the 25-year period between 1991 through 2015. This research documents the continued growth (Bernardi & Bean, 2007) of accounting-ethics research in both accounting-ethics and business-ethics journals. We provide data on the top-10 ethics authors in each doctoral year group, the top-50 ethics authors over the most recent 10, 20, and 25 years, and a distribution among ethics scholars for these periods. For the 25-year timeframe, our data indicate that only 665 (274) of the 5,125 accounting PhDs/DBAs (13.0% and 5.4% respectively) in Canada and the United States had authored or co-authored one (more than one) ethics article.
