A computer-aided bibliometric system to generate core article ranked lists in interdisciplinary subjects

Due to the tremendous increase and variations in serial publications, the impact of every peer-reviewed paper on different subjects is varying continually. Domain experts or researchers want to keep track of those latest and highly cited peer-reviewed papers; however they are finding it difficult to update or collect their subject core paper lists regularly and accurately. The evaluation of serial papers for generating and ranking core paper lists on different subjects becomes a very challenging task for scholars or librarians. Therefore, a computer-aided bibliometric system (CABS) was developed to generate a core article ranked list automatically. Four indicators - subject reference cited counts, subject total cited counts, subject reference period impact and subject reference cited history - were proposed to generate a subject core article ranking list. Seven different subjects including E-commerce, Data Mining, Supply Chain, Image Processing, Enterprise Resource Planning, Microarray and Expert Systems were used as samples. The turning point (TP) was proposed to determine the core article area in the paper citation analysis. The TP patterns observed were that all TPs had the same rate for four different subjects. The usage of TP patterns can also be used to verify the experimental results. This study provides experimental evidence to disprove three myths. Myth 1: the top papers on a subject (for instance, the top 10 papers) were all submitted to (S)SCI journals. Myth 2: the highly cited papers (cited counts >4) on interdisciplinary subjects were almost submitted to (S)SCI journals. Myth 3: the articles published in the top journals on a subject would be highly cited.     

Assessing the impacts of digital transformation on internal auditing: A bibliometric analysis

During the last years, the impacts caused by digital transformation on companies have been disruptive. Contrarily to prior technological revolutions, the current scenario is characterized by the rapid growth of innovation that has impacted organizations differently. In particular, an increasing number of organizations revised their management control systems to adequate their business models to the external pressures made by competitors and regulators. The research aims consist of a bibliometric analysis about the impacts caused by digital transformation on managerial auditing. The research reveals the existence of four independent research area: continuous auditing (Green Cluster), fraud detection (Blue Cluster), data analytics (Yellow Cluster) and technological innovation (Red Cluster). Finally, we developed a research agenda in order to address future research.

Assessing fuel cell vehicle innovation and the role of policy in Japan,Korea, and China

Despite intensive public and private research efforts into developing fuel cell vehicles (FCV), the global number of FCV remains small and they are unavailable for commercial purchase. We use an in-depth literature review, and bibliometric and patent analysis to analyse FCV technology within the conceptual framework of Rogers' innovation diffusion curve and suggest how the particular innovation systems and policies adopted in three key Asian car-manufacturing countries (Japan, Korea, and China) have influenced the development of FCV. Such analysis may capture trends not indicated by technical measures such as increases in efficiency or decreases in unit cost. Although Japan continues to lead in terms of number of patents and quality of academic research, Korea and China have been successful in developing fuel cell programs. Korean academics patent more frequently than their Japanese and Chinese peers, producing 18% of FC patents, with 16% of those filed also naming a private company. The 2008 financial crisis and ongoing economic uncertainty appears to have had some effect on patent activity whilst academic research appears unaffected. Diffusion curve analysis suggests that FCVs have not reached technological maturity.     

Sodium borohydride as a fuel for the future

In a time of unprecedented change in environmental, geopolitical and socio-economic world affairs, the search for new energy materials has become a topic of great relevance. Sodium borohydride, NaBH₄, seems to be a promising fuel in the context of the future hydrogen economy. NaBH₄ belongs to a class of materials with the highest gravimetric hydrogen densities, which has been discovered in the 1940s by Schlesinger and Brown. In the present paper, the most relevant issues concerning the use of NaBH₄ are examined. Its basic properties are summarised and its synthesis methods are described. The general processes of NaBH₄ oxidation, hydrolysis, and monitoring are reviewed. A comprehensive bibliometric analysis of the NaBH₄ publications in the energy field opens the discussion for current perspectives and future outlook of NaBH₄ as an efficient energy/hydrogen carrier. Despite the observed exponential increase in the research on NaBH₄ it is clear that further efforts are still necessary for achieving significant overchanges.     

Materials selection using patent information: A function- and application-based analysis of aircraft interior structures

Materials selection in product design is a complex decision-making activity due to the necessity of embodying technical requirements into those related to customer, safety, environmental, economic and social aspects. Technological developments have been increasing materials options, thus demanding the manipulation of large amounts of information and data to identify them. This study proposes a monitoring procedure to identify and select materials in innovative product design using patent information. It applies bibliometric techniques to select relevant patents using two different retrieval strategies: (i) driven by the function and (ii) by the application of the product. A case study to search for a more sustainable composite material for aircraft interior structures reveals distinct sets of data and types of technical solutions depending on the patent retrieval strategy used. The function-based patent retrieval strategy found more disruptive solutions, whereas the application-based strategy identified mainly improvements in current technology developed by partners of the aeronautical industry.
