    Subjects: Library Science,Information Science >> Library Science submitted time 2023-08-26 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] Investigating the main features and the correlation with conventional bibliometric indicators of Altmetrics, the variation of features and correlation with the time, and its comprehensive evaluation on both social and academic influences of academic papers are crucial for both development and improvement of Altmetrics.[Method/process] In this paper, we took Altmetric Top 100 papers from 2014 to 2016 as samples, analyzed their source journal, discipline category, access method and authors' affiliation, and further discussed their social influence. At the same time, we investigated the relationship between Altmetric scores of these Altmetric Top 100 papers and their citation counts from Web of Science, and the variation of such relationship with the time.[Result/conclusion] The results showed that most papers with high Altmetric scores are from high-profile journals with high impact factors, and are in fields of medical & health sciences and biological sciences. Most authors of these papers with high Altmetric scores are from the institutes with high research level in United States of America, United Kingdom and Germany. The fraction of free-accessed papers in the papers with high Altmetric scores increases annually. Altmetric score can quantitatively reflect the amount of attention that the social medias pay to the academic papers, which to some extent indicates the social influence of these academic papers. Altmetric scores of Altmetric Top 100 papers positively correlate their citation counts, implying that these papers with high Altmetric scores have significant academic influence.

  • Is the Contribution of the Non-Citable Items to the Impact Factor Significant or not—— an Empirical Study Based on Large Samples in the Past Five Years

    Subjects: Library Science,Information Science >> Philology submitted time 2023-01-13

    Abstract:

    Purpose/Significance Based on the controversy about the formula of impact factor in academics, this paper explores if the contribution of the non-citable items to the journal’s impact factor is abnormal, making the journal’s impact factor can not correctly reflect the academic impact of the journal itself. Method/Process Using the citation data of all types of journal articles from 2017 to 2021 published in the Web of Science core database, the contribution to the journal impact factors made by non-citable items in the recent five years were calculated and analyzed. Results/Conclusion On the whole, the contribution of non-citable items to the impact factors in the past five years was at a low level and little changed, and there were no obvious signs that exist the behavior of manipulating influencing factors. Therefore, it is not necessary to question the rationality of the calculation formula of the impact factor due to worry that the impact factor is being manipulated.

    Subjects: Library Science,Information Science >> Library Science submitted time 2023-07-26 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] Study of the influencing mechanism of users' recognition of answers is helpful to identify central path and edge path, to retain users with high influence power, to guarantee high quality questions and answers, then to increase community activity.[Method/process] After building a theoretical model about answer recognition, collecting data from 1964 posts on the NPC Economic Forum, Smartpls software is used to analyze the data.[Result/conclusion] User activity can affect user influence and answer quality separately, thus affecting the degree of answer recognition in E-learning communities. Answer quality affects user influence as well. The impact of user influence power on answer recognition is far more than that of answer quality, that is, the edge path has a greater impact than the central path.

  • 积极刻板印象会产生消极?

    Subjects: Psychology >> Social Psychology submitted time 2023-03-28 Cooperative journals: 《心理科学进展》

    Abstract: Positive stereotypes are defined as positive traits describing social groups. Previous research on stereotypes has mainly focused on negative stereotypes while overlooking positive stereotypes, especially their negative effects. Here, we will discuss positive and negative effects of positive stereotypes from racial, gender and aging stereotypes and conditions for their emergence and further future research. The positive effects of positive stereotypes are mainly evinced through the stereotype boost. For example, activation of positive racial stereotypes, positive gender stereotypes and positive aging stereotypes has a positive effect on targets’ minds and behaviors. The negative effects of positive stereotypes on targets’ behaviors and cognition are caused by the choking under pressure effect and compensation effect of social cognition, respectively. For example, targets with positive racial stereotypes have negative attitudes and evaluations towards the stereotyper. Targets are prone to underperform in stereotyped domains in positive gender stereotypes situation. As for positive aging stereotypes, the mental and psychical health of targets can be adversely affected. Generally, positive stereotypes still induce negative effect similar to negative stereotypes in certain conditions, although having the positive side. The effects (positive or negative) of positive stereotypes depend on the following four moderators: (1) Activation of positive stereotypes. Compared with the subtle activation of positive stereotypes, blatantly activating positive stereotypes easily cause the “choking under pressure” of targets and their sense of being depersonalized, finally resulting in a negative impact. (2) Accuracy of expressing positive stereotypes. Compared with accurately expressing positive stereotypes, the one who states positive stereotypes in an extreme way tends to generate the feeling of untruth, resulting in conflicted response of targets. (3) Individuals who state positive stereotypes. Compared with an ingroup member, positive stereotypes stated by an outgroup member easily cause the prejudice by targets, which then result in targets’ negative attitudes and evaluations towards the stereotyper. (4) Culture context of positive stereotypes. Compared with collectivistic culture, positive stereotypes in individualistic culture are prone to have a sense of being depersonalized and be thread. Further research on positive stereotypes can be discussed from the following aspects: (1) Exploration of effects of positive stereotypes in collectivistic culture. For example, China is the representative country of collectivistic cultures which emphasize “fundamental connectedness of human beings to each other”, and positive stereotypes as positive beliefs about members of social groups based on the category membership. Therefore, the Chinese feel less depersonalized when the stereotyper describe them in ways related positive stereotypes. (2) Exploration of positive stereotypes from research fields and targets, such as fields of sexual orientation and academic discipline. Academic discipline stereotypes deem that science students are superior to arts students in science, and arts students are superior to science students in arts. As a result, male science students may underperform on the science test and female arts students may underperform on the arts test when priming their major and gender identities simultaneously, due to the feeling of untruth present when activating two positive stereotypes. In addition, researchers can explore positive stereotypes of children as there are no stereotype awareness of children under 7 ages. That is one of the prerequisites for positive stereotypes having influence on targets. (3) Exploration of interventions of negative effects reduced by positive stereotypes. By far there is no research on the interventions of negative effects of positive stereotypes. However, it is not hard to assume that would be difficult to reduce the negative effects of positive stereotypes because of the complimentary nature of positive stereotypes. (4) Exploration of positive effects of negative stereotypes. Based on our knowledge, only two studies have found that negative stereotypes have positive consequences. Once more empirical evidence to support the findings can be confirmed, this would play a significant role in the domain of stereotype research, especially for the interventions of negative effects of stereotypes.

    Subjects: Library Science,Information Science >> Library Science submitted time 2023-10-08 Cooperative journals: 《知识管理论坛》

    Abstract: [Purpose/significance] This paper aims to build a model for benchmarking analysis of two institutions by using ESI and InCites databases. It provides a feasible approach for comprehensive, quantitative and public comparison and analysis of the international delivery performance of benchmarking institutions. [Method/process] We used the index provided by ESI and InCites, including Web of Science documents, citation times, category normalized citation impact. According to the different literature contribution, we proposed three new concepts, all documents, leading documents and not-leading documents. We put forward a new index—participation rate to measure the paper competitiveness of the agencies. We compared the general paper competitiveness, the affiliated author, the cooperative organization and the publication of journals of two universities. [Result/conclusion] In this paper, Web of Science documents are used to describe the quantity of the document issued by the organization. The category normalized citation impact and citation times are used to describe the quality of the document issued by the organization. For A university, the number of documents is dominant, and for B university quality is dominant. According to the author’s data analysis, B’s top authors of international publications have greater influence, ranking in the front row. According to the data analysis of the cooperation institution, the cooperation between the best cooperation institutions in B is more efficient, and the cooperation between the two sides makes the international ranking more advanced. It is the main reason for the quality of published papers of B university that the impact factors of the periodicals where papers of B university published are much higher.

  • 自强还是自嘲?名人代言如何提升社会化媒体广告的营销效果

    Subjects: Psychology >> Social Psychology submitted time 2023-03-27 Cooperative journals: 《心理学报》

    Abstract: Recent years have witnessed the increasing prevalence of celebrity endorsement as advertising in China. The reason for this increased prevalence is that celebrity endorsements can boost the credibility and attractiveness of advertisements and therefore lead to increased profits for companies in most cases. In the social media environment, the influence of celebrities is amplified remarkably by the following of their fans. Previous studies have demonstrated that the effect of celebrity endorsements is mostly positive or self-enhancing. However, this effect does not always apply in social media platforms. For example, several celebrity endorsements actually contain self-deprecating content. In this study, we explored the role of self-enhancement and self-deprecation in celebrity endorsement effectiveness and examined their impact on consumers’ intent to share. Furthermore, we introduce the moderating effect of product types, namely, whether a product is utilitarian or hedonic. To obtain preliminary insights, we collected 86 micro-blog posts with celebrity endorsements and coded them as either self-enhancing or self-deprecating posts. Analysis of secondary data showed that consumers shared numerous self-enhancing celebrity endorsement posts with regard to hedonic products, and consumers shared many self-deprecating celebrity endorsement posts with regard to utilitarian products. Subsequently, we conducted laboratory studies to validate our hypothesis further. First, we performed a robust test on the effect of different celebrity endorsements on consumers’ intent to share. The results of the two types of celebrity endorsements (self-enhancing and self-deprecating) indicated the effect of self-deprecating celebrity endorsement on consumers’ intent to share was stronger than that of self-enhancing celebrity endorsement. Second, we examined the interactive effect of celebrity endorsements and product types and the mediating role of social influence. As expected, the 2 (celebrity endorsements: self-enhancing vs. self-deprecating) × 2 (product types: utilitarian vs. hedonic) subject design experiment suggested that participants in the utilitarian product condition were willing to share self-deprecating content, and this effect was caused by informative influence. On the contrary, participants in the hedonic product condition were willing to share self-enhancing content, and this effect was driven by normative influence. Our research contributes to literature on celebrity endorsement in social media by focusing on consumers’ sharing intention rather than purchase behavior. First, this research explores whether self-deprecating celebrity endorsement can strengthen consumers’ intent to share or not. Second, this study provides a new perspective on celebrity endorsement by differentiating its content into two types: self-enhancing and self-deprecating. Third, this research examines the impact of product difference in celebrity advertisement. It reveals that consumers in different product conditions might share different celebrity endorsement advertisements. Finally, we demonstrated the mediation mechanism of the interaction between celebrity endorsement and product type by examining consumers’ sharing intention. Aside from this empirical demonstration, our research also presents many useful implications for companies with regard to the design of celebrity endorsement.

  • Analysis on the Effectiveness of Citation Evaluation Methods in the Research Field Identification by Co-Citation Network

    Subjects: Library Science,Information Science >> Information Science submitted time 2023-04-01 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] To investigate field-normalized reference influence indicators on the level of papers, the effectiveness of a citation evaluation method (Relative Citation Ratio, RCR) based on the research field identification by co-citation network is analyzed.[Method/process] In order to test the effectiveness of RCR in the evaluation of academic impact, the paper chose iCite, F1000, InCites, then took 739 604 articles as a sample, and analyzed the correlation among RCR, Category Normalized Citation Impact (CNCI) and journal impact factor (JIF) by the R language.[Result/conclusion] The paper shows that RCR strongly correlates with CNCI, and poorly correlates with journal impact factor, which indicate the similarities and differences between RCR and CNCI and confirm that it is a good practice for implementing San Francisco Declaration on Research Assessment and assessing research on its own merits rather than on the basis of the journal in which the research is published. It also turns out the inverse relationship of the correlation and the number of interdisciplinary subjects between RCR and journal impact factor in interdisciplinary science, and lower correlation between RCR and journal impact factor than in a single discipline, which appears the applicability and effectiveness of RCR in evaluating the influence of academic papers in interdisciplinary science. The paper concludes that RCR based on research field identification by co-citation network provides new solution for the evaluation of paper influence, especially for interdisciplinary research outputs.

    Abstract: [Purpose/significance] This paper aims to explore the effectiveness of Altmetrics in revealing the impact of academic books, and then put forward reasonable suggestions for academic book evaluation. [Method/process] Four Altmetrics indicators, Twitter reference, Mendeley reading, text review and libcitation are collected. After analyzing the coverage, quantiles and other statistics of books, the correlation between book citation and Altmetrics indicators is carried out. Books of high indicator values are evaluated from the aspects of published year, discipline and subject in order to explore the application of these indicators in the use of book impact evaluation. [Result/conclusion] The low correlation between book citation and Altmetrics indicators shows that Altmetrics can be used as a new perspective for evaluating academic books, and different Altmetrics indicators reveal different dimensions of book impact. It is suggested to combine Altmetrics indicators and citation and make more use of the characteristics of books such as year and discipline in the future research of book impact evaluation.
