通过对影响因子评价学术期刊的科学性和局限性的分析,认为影响因子是评价学术期刊的重要指标.指出在评价学术期刊时,影响因子的客观性、系统性、科学性和实用性已得到了认可,学术期刊要正确运用影响因子,发挥影响因子的客观性和科学性的作用,提高期刊各影响因子指数,以便影响因子更能体现期刊的影响范围,从而更好地、科学地评价期刊,使影响因子成为有利于作者、读者、编辑和期刊的科学评价因素. 相似文献

运用面板向量自回归模型分析后发现：东部地区图书出版对经济增长带来了“先增强后减弱”的正向冲击效应,中部地区的冲击效应既不明显也不稳定,西部地区则呈现负向冲击效应。同时,东部地区出版产业的延伸和知识的外溢使得全国的图书出版带来经济的有效增长。但是,这一效应主要是通过“产业渠道”而非“传播渠道”传导的,这就使得图书出版数量上的扩张只是带动了出版产业的发展,而未能带来出版知识快速且有效的转化。 相似文献

图书出版分别通过"传播渠道"和"产业渠道"带来间接和直接的经济绩效.其中,"传播渠道"由于从供给层面影响了经济增长的制度环境和创新能力,因此其经济效应具有见效慢但却逐渐增强的特征;而"产业渠道"则从需求层面直接带来需求的增加,因此其经济效应见效快但却存在逐渐减弱的趋势.发挥图书出版在经济发展中的促进作用,应在继续扩大出版规模的同时,进一步提升图书出版的质量.从提升思路上来看,应注意传统纸媒与新兴媒体和现代"智造业"的有机融合,应加强知识产权制度的保障作用和激励作用,应加大对社科工作者和技术创新人员的经费投入. 相似文献

Publication bias can occur when a study is not published in an academic journal because the study did not find a statistically significant result. It can bias meta-analytic estimates upwards because the meta-analyses are missing studies that provide small estimates of the effect size under study. This paper describes the trim and fill technique of estimating the impact of publication bias on meta-analyses (Duval & Tweedie, 2000a, 2000b) and provides a working example. A sample of 68 meta-analyses of communication research were tested for publication bias using the trim and fill technique. The results suggest that most communication meta-analyses are not substantially affected by publication bias. 相似文献

The journal impact factor (JIF) has been questioned considerably during its development in the past half-century because of its inconsistency with scholarly reputation evaluations of scientific journals. This paper proposes a publication delay adjusted impact factor (PDAIF) which takes publication delay into consideration to reduce the negative effect on the quality of the impact factor determination. Based on citation data collected from Journal Citation Reports and publication delay data extracted from the journals’ official websites, the PDAIFs for journals from business-related disciplines are calculated. The results show that PDAIF values are, on average, more than 50% higher than JIF results. Furthermore, journal ranking based on PDAIF shows very high consistency with reputation-based journal rankings. Moreover, based on a case study of journals published by ELSEVIER and INFORMS, we find that PDAIF will bring a greater impact factor increase for journals with longer publication delay because of reducing that negative influence. Finally, insightful and practical suggestions to shorten the publication delay are provided. 相似文献

The purpose of this study was to examine the relationship between publication rate, top journal publications and excellence during the first eight years of the career, and how well publication rate, top journal publications and highly cited publications during the first four years of the career can predict whether an author attain excellence in the fifth to the eighth year. The dataset consisted of publication track records of 406 early career mathematicians in the sub-field of number theory collected from the MathSciNet database. Logistic regression and dominance analysis was applied to the data. The major conclusions were (1) publication rate had a positive effect on excellence during the first eighth years of the career. However, those who publish many articles in top journals, which implicitly require a high publication count, had an even higher probability of attaining excellence. These results suggest that publishing in top journals is very important in the process of attaining excellence in the early career in addition to publishing many papers; and (2) a dominance analysis indicated that the number of top journal publications and highly cited publications during the first four years of the career were the most important predictors of who will attain excellence in the later career. The results are discussed in relation to indicator development and science policy. 相似文献

Choosing a publication venue for an academic paper is a crucial step in the research process. However, in many cases, decisions are based solely on the experience of researchers, which often leads to suboptimal results. Although there exist venue recommender systems for academic papers, they recommend venues where the paper is expected to be published. In this study, we aim to recommend publication venues from a different perspective. We estimate the number of citations a paper will receive if the paper is published in each venue and recommend the venue where the paper has the most potential impact. However, there are two challenges to this task. First, a paper is published in only one venue, and thus, we cannot observe the number of citations the paper would receive if the paper were published in another venue. Secondly, the contents of a paper and the publication venue are not statistically independent; that is, there exist selection biases in choosing publication venues. In this paper, we formulate the venue recommendation problem as a treatment effect estimation problem. We use a bias correction method to estimate the potential impact of choosing a publication venue effectively and to recommend venues based on the potential impact of papers in each venue. We highlight the effectiveness of our method using paper data from computer science conferences. 相似文献
