Abstract: We carry out a bibliometric study of the activity of astronomers in the field of Herbig-Haro (HH) objects. Through an appropriate choice of keywords, we recover the papers on HH objects from the ADS (Astrophysics Data Service) and ISI (“Web of Knowledge”) databases. From the two databases we recover number of papers and citations which differ by similar to 10%. We analyze an 11-year period, restricting ourselves to authors with at least 10 papers within the period. We analyze the number of papers and citations, as well as the H index of this set of authors. Within this sample, we identify the authors belonging to Mexican institutions. We find that the Mexican researchers perform very well, having higher publication and citation rates than the ones of the full sample of authors active in the field of HH objects. The Mexicans have a degree of specialization (measured as ratios between the production in the chosen field and the total production of the individual authors) similar to the one of the full sample. They collaborate in somewhat larger groups than the authors of the full sample. Finally, we have carried out a study of the impact in the chosen field of different astronomical journals. We find that the Revista Mexicana de Astronomia y Astrofisica is well placed in the “second tier” of astronomical publications.

Abstract: The h-index is becoming a reference tool for career assessment and it is starting to be considered by some agencies and institutions in promotion, allocation, and funding decisions. In areas where h indices tend to be low, individuals with different research accomplishments may end up with the same h. This paper proposes a multidimensional extension of the h index in which the conventional h is only the first component. Additional components of the multidimensional index are obtained by computing the h-index for the subset of papers not considered in the immediately preceding component. Computation of the multidimensional index for 204 faculty members in Departments of Methodology of the Behavioral Sciences in Spain shows that individuals with the same h can indeed be distinguished by their values in the remaining components, and that the strength of the correlation of the second and third components of the multidimensional index with alternative bibliometric indicators is similar to that of the first component (i.e., the original h).

Abstract: This paper examines the peer review procedure of a national science funding organization (Swiss National Science Foundation) by means of the three most frequently studied criteria reliability, fairness, and validity. The analyzed data consists of 496 applications for project-based funding from biology and medicine from the year 1998. Overall reliability is found to be fair with an intraclass correlation coefficient of 0.41 with sizeable differences between biology (0.45) and medicine (0.20). Multiple logistic regression models reveal only scientific performance indicators as significant predictors of the funding decision while all potential sources of bias (gender, age, nationality, and academic status of the applicant, requested amount of funding, and institutional surrounding) are non-significant predictors. Bibliometric analysis provides evidence that the decisions of a public funding organization for basic project-based research are in line with the future publication success of applicants. The paper also argues for an expansion of approaches and methodologies in peer review research by increasingly focusing on process rather than outcome and by including a more diverse set of methods e.g. content analysis. Such an expansion will be necessary to advance peer review research beyond the abundantly treated questions of reliability, fairness, and validity.

Abstract: This paper examines how Korean technological development is linked with scientific activities and spreads to industrial fields through knowledge flows. It empirically assesses the linkages between scientific and technological knowledge flows and technological innovation by determining whether the quantity and quality of scientific papers cited by, and the knowledge being absorbed in, Korean patents filed in USPTO varied over time, and between technology fields. We conducted MANOVA and then canonical discriminate analysis. Our findings are: the patterns of both the absorption of scientific knowledge and the diffusion of technological knowledge differ by period and by field, and the speed of knowledge diffusion differs by technology field. This implies that the time required for Korean investment in basic and applied research to impact her industrial innovation differs by technology field.

Abstract: This study aims at detecting the role of individual journals and uncovering structural patterns of information flow among scientific journals in a cross-citation network, using different bibliometric indicators and statistical methods of data analysis. Beyond measuring the individual journals’ position within the communication network, we shed light on their cognitive background as well. Language barrier and lacking internationality proved one of the main hindrances for integration into the communication network. Moreover, some document types hinder journals from establishing self-links. Against our expectations, we have found a clear divergence between strongly interlinked and high-entropy journals. Furthermore, the analysis of strong links among different fields allows the detection of high-interdisciplinary journals.

Abstract: Based on data from the Science Citation Index Expanded (SCIE) and using scientometric methods, we conducted a systematic analysis of Chinese regional contributions and international collaboration in terms of scientific publications, publication activity, and citation impact. We found that regional contributions are highly skewed. The top positions measured by number of publications or citations, share of publications or citations are taken by almost the same set of regions. But this is not the case when indicators for relative citation impact are used. Comparison between regional scientific output and R&D expenditure shows that Spearman’s rank correlation coefficient between the two indicators is rather low among the leading publication regions.

Abstract: We studied the influence of the number of citations, the number of citable items and the number of journal self-citations on increases in the impact factor (IF) in 123 journals from the Journal Citation Reports database in which this scientometric indicator had decreased during the previous four years. In general, we did not find evidence that abuse of journal self-citations contributed to the increase in the impact factor after several years of decreases.

Abstract: Carbon nanotube field emission display (CNT-FED) represents both emerging application of nanotechnology and revolutionary invention of display. Therefore, it is an important subject to monitor the states and trends of CNT-FED technology before the next stage of development. The present paper uses patent bibliometric analysis and patent network analysis to monitor the technological trends in the field of CNT-FED. These results firstly reveal the different aspects of patenting activities in the field of CNT-FED. Then, patent network analysis indicates the developing tendency of worldwide FED production based on the synthesis of CNT materials. Furthermore, key technologies of three clusters can be identified as the depositing CNT on substrate, coating phosphor on screen and assembling process for whole device. Finally, emitter material is taken for the key factor in R&D work to improve the efficacy in CNT-FED technology.

Abstract: Patents contain much significant technical information which can serve as an indicator of technological and economical development. This study attempts to forecast the development of the biped robot walking technique in Japan by use of the patent data obtained from the Japan Patent Office. The study applies linear regression to the patent data using three S-curve models developed by Loglet Lab, Pearl, and Gompertz individually. Various parameters inherent to each model including the least sum of modulus error and the least mean of square error of the model are analyzed. The most appropriate model for measuring the inflection point, the growth and the saturation time of the technique is described. Based on the Gompertz model analysis, this study finds that the biped robot walking technique will continue to develop for several decades in Japan and the saturation period is estimated to be around the year 2079-2082. This finding can help related researchers and managers in the robot field to foresee the development trend of the biped robot walking technique in this century.

Abstract: Although the topic of technological diversification has been a major source of research, only a few studies have explored the determinant variables of technological scope decisions. The present study enhances our understanding of the determinants of a firm’s technological scope strategy. After reviewing the related literatures, we proposed and empirically tested a conceptual model from the perspective of the firm’s environment, strategic orientation, and resources. The results suggest that the coherence between technological scope decisions and proposed model is significantly related to performance.

Abstract: The relationship between R&D and market value has attracted the interest of many scholars within different fields, but scant attention has been paid to the countries with weak protection of intellectual property rights (IPR). This is unfortunate, since this problem is potentially highly relevant for IPR policy in developing countries. In particular, several questions arise when the problem of R&D market value is analyzed in a country where IPR protection is weak. First, there are concerns regarding incentives (i.e., private returns) for firms to invest in R&D when IPR is only weakly protected. Second, significant differences could emerge in the market valuation of R&D investments of domestic and foreign firms, above all in those industries where spillovers are more likely. To examine these issues, this paper investigates the market valuation of R&D investments of a panel of 219 R&D-reporting domestic and foreign firms publicly traded in India with an empirical analysis. First, the market valuation of the R&D capital for the whole sample is positive and higher than those obtained in U.S. or European countries from similar analyses. Second, in the sub-samples of the domestic and foreign firms, the market value of R&D investments of foreign firms is not significantly different from zero, while the valuation coefficient of domestic firms is four times higher than that obtained on the whole sample. Third, in science-based industries the difference between domestic and foreign firms is smaller than in the other industries. The policy implications of these findings are discussed.

Abstract: This study utilized artificial neural network (ANN) to explore the nonlinear influences of firm size, profitability, and employee productivity upon patent citations of the US pharmaceutical companies. The results showed that firm size, profitability, and employee productivity of the US pharmaceutical companies had the nonlinearly and monotonically positive influences upon their patent citations. Therefore, if US pharmaceutical companies want to enhance their innovation performance, they should pay attention on their firm size, profitability, and employee productivity.

Abstract: Because R&D conducted in electronics and chemistry has made significant contributions to South Korean economic development, past strategies in technology developments in these fields are addressed. The possibility of capturing national technology strategy and policy characteristics from patent analyses is explored. For the analysis, data were analyzed from 557 US patents in electronics and 108 US patents in chemistry, registered by Korean inventors, between 1989 and 1992. Descriptive statistics of aggregated patent information were equivalently mapped to each strategy in the two fields. Industry-specific features and past technology strategies in electronics and chemistry are identified. Electronics was driven by the private sector, while chemistry was driven by the public sector. Inventors in both fields are seeking clustered innovation on which subsequent innovation can be accumulated and/or applied to numerous heterogeneous fields. Contrary to the stated assumption, many Korean electronic innovations were based on scientific outputs such as papers. Of the knowledge strategy variables, size of invention and number of heterogeneous classifications are considered to be an important factor that affects patent citation counts in both fields.

Abstract: This paper adds to the growing empirical evidence on the relationship between patenting and publishing among university employees. Data from all Norwegian universities and a broad set of disciplines is used, consisting of confirmed patent inventors and group of peers without patents matched to the inventors by controlling for gender, age, affiliation and position. In general, the findings support earlier investigations concluding that there is a positive relationship between patenting and publishing. There are, however, important differences among fields, universities and possibly types of academic entrepreneurs, underscoring the need to look at nuanced and contextual factors when investigating the effects of patenting.

Abstract: In this study, the author tried to demonstrate the linkage between science research and technology development through non-patent citation analysis to reveal that the important knowledge resources from science research had significant impact on technology development. Genetic engineering technology was the field examined in this study. From the references listed in the patents, it was observed that the technology development in genetic engineering was influenced heavily by the research done by public sector. Over 90% of the citations were non-patent literatures, and the majority of non-patent citations were journal articles. Citing preferences, such as country preference and institute preference were observed from the data included in this study.

Abstract: Despite strategic research has been done in recent years to study how network topology shapes the evolution of competition in various industries, previous researches do not investigate the importance of high betweenness point on the connectivity of patent citation networks. The goal of this report is to examine and characterize the small world phenomenon in the patent citations network by analyzing the data of RFID patents. The results suggest that the patent citation network can indeed be characterized as “small world”. Additionally, the patent citation network resembles the power-law connectivity distribution and exhibits preferential connectivity behavior. In other words, a few key patents have a great many more connections than the majority of patents with few connections. Furthermore, the patents of high betweenness centrality were identified. It is found that 81% of the patent citation activities have relations with the patents of high betweenness centrality. The result of this analysis will provide a specific way for managers to identify key patents, to map their own patent deployment and to derive insight into the best ways to navigate within such networks.

Abstract: In recent years, firms have increased their use of internal and external knowledge through intermediaries. Knowledge brokers match buyers and sellers in the technology marketplace as well as connect and combine existing knowledge. We discuss how financial incentives in the technology marketplace can address challenges to open innovation, and how the marketplace could make individual inventors essential contributors. And then, we identify the key determinants of intellectual-property auction bids and different characteristics of auctioned and non-auctioned patents. Relevance, the scope of patents, and other factors suggested in the literature impact patent auctions, as mediated by knowledge brokers.

Abstract: The objective of this research is to develop a new patent bibliometric performance measure by using modified citation rate analyses with dynamic backward citation windows. Cited half-life employed in bibliometrics was adopted in order to establish a model of annual patent backward citation windows. Based on the dynamic behavior of backward citation windows, the annual backward patent citation rates for each technology domain can be calculated to measure its bibliometric performance. It was found that the dynamic backward citation window represents more accurately the citation cycle time which is a key factor on technology assessment. Because different technology domain may have disparate attributes, a normalized backward citation rate was developed to measure the corresponding rank for each domain respect to the entire industry. Three technology domains were then chosen for demonstrative case studies which represent semiconductor, LCD, and drug industries.
