This study aims to thoroughly explore and visualize the trends and developments of digital twin (DT) literature in the construction field while revealing future research directions for further exploration and exploitation.

The research follows a three-stage methodology. First, the bibliographic data is acquired using the Web of Science database. Second, the bibliometric methods are defined to include co-authorship analysis, citation analysis, keywords co-occurrence, thematic mapping while the software tools include MS Excel, VOSviewer and Biblioshiny. Third, analysis and findings include yearly DT publication output, influential DT publications, leading DT contributors, top DT sources and science mapping of DT literature.

This study identifies top-cited DT publications (35 out of 320) in terms of citations score, local citations score and document average citations per year. Furthermore, the key contributors with respect to authors (58 out of 1147), organizations (55 out of 427) and countries (19 out of 51) are recognized in terms of productivity, influence, activeness and scientific value. Similarly, the major publishing sources (24 out of 58) are identified using the same measures. Regarding science mapping, the DT domain comprises four research frontiers, namely, deep learning and smart city, internet of things and blockchain, DT and building information modeling and machine learning and asset management.

Through a mixed-review strategy, this study introduces a comprehensive analysis of DT literature while avoiding the subjectivity/cognitive bias of traditional review approaches. Moreover, it illuminates the promising and rising DT themes for new/seasoned researchers, institutions, editorial boards and funding agencies.

The purpose of this study is to investigate the information-seeking behavior of Egyptian parents of autistic children.

The study sample consists of 61 parents across Egypt, divided into six focus groups, as equal as possible, to represent Northern, Middle and Southern Egypt.

Dmographically, of the 61 parents, 32 (52.5%) were fathers, and 29 (47.5%) were mothers. A large number of parents' ages ranged from 31 to 45 years old. The highest percentage of them was holding a BA, followed by a high school/diploma, and the highest percentage was found to be married. The parents of autistic children followed many methods and channels to obtain supportive information related to their children's disease. They used many types of information, which varied between formal and informal sources. While just over a quarter of Egyptian parents prefer to use formal sources (books, newspapers, magazines, health publications, pamphlets, as well as specialized libraries), more than three-quarters of them used informal sources, such as mobile/smartphones, the Web, social media and social networking sites. The information related to the search for institutions supporting autistic people came in the first place, then that information related to searching for specialized centers in treating autistic children, then information related to rehabilitation, integration and psychological support centers for these children and then information related to the search for financial aid provided by charitable or even government agencies. Some parents were found to have limited awareness of their children's treatment mechanism, as some of them do not consider the need to treat their children in a systematic, continuous, and systematic manner. Similarly, the lack of basic services and shortage of government centers specializing in the treatment of these children. Parents also emphasized the lack of government support, as well as the lack of curative research centers. Some also pointed out that there was a shortage of workshops for the rehabilitation of their children and themselves as well.

This research is considered to be the first research of its kind at the local and Arab levels, which is also one of the few studies at the regional level that is interested in this community of information seekers. The findings of this research can raise awareness about the information behavior of Egyptian parents of autistic children among those who are interested in the role of the information and its use by specific groups of the information society, as well as decision makers.

This research is a 6-year extension of Bernardi's (2005) initial ranking of the top ethics authors in accounting; it also represents a broadening of the scope of the original data into accounting's top-40 journals. While Bernardi only considered publications in business-ethics journals in his initial ranking, we developed a methodology to identify ethics articles in accounting's top-40 journals. The purpose of this research is to provide a more complete list of accounting's ethics authors for use by authors, administrators, and other stakeholders. In this study, 26 business-ethics and accounting's top-40 journals were analyzed for a 23-year period between 1986 through 2008. Our data indicate that 16.8 percent of the 4,680 colleagues with either a PhD or DBA who teach accounting at North American institutions had authored/coauthored one ethics article and only 6.3 percent had authored/coauthored more than one ethics article in the 66 journals we examined. Consequently, 83.2 percent of the PhDs and DBAs in accounting had not authored/coauthored even one ethics article.
