Beyond Journal Impact and Usage Statistics: Using Citation Analysis for Collection Development     

Wenli Gao 《期刊图书馆员》2016,70(1-4):121-127

This article outlines a methodology to generate a list of local core journal titles by doing a citation analysis and details the process for retrieving and downloading data from Scopus. It analyzes correlations among citation count, journal rankings, and journal usage. The results of this study reveal significant correlations between journal rankings and journal usage. No correlation with citation count has been found. Limitations and implications for collection development and outreach are also discussed.  相似文献

浅圆仓侧压力分析     

原方  范量  高新南 《东南大学学报》2004,20(3):356-359

Rankine理论和Coulomb理论均不适合用于浅圆仓的侧压力计算. 基于此, 本文研究了浅圆仓散料侧压力的实际分布规律及计算方法. 根据极限平衡理论, 首先得到散粒体作用在单位周长的仓壁上的合压力, 然后通过严格的数学推导, 得到浅圆仓侧压力的分布规律. 结果表明, 本文结果与实仓试验结果相符, 说明本文公式不论对平堆还是锥堆都比较适合, 而Rankine理论和Coulomb理论用于浅圆仓均有缺陷.  相似文献   

A channel distortion model for video over lossy packet networks     

Cheng Jian-xin  Gao Zhen-ming  Zhang Zhi-chao 《浙江大学学报(A卷英文版)》2006,7(1):48-53

Error-resilient video communication over lossy packet networks is often designed and operated based on models for the effect of losses on the reconstructed video quality. This paper analyzes the channel distortion for video over lossy packet networks and proposes a new model that, compared to previous models, more accurately estimates the expected mean-squared error distortion for different packet loss patterns by accounting for inter-frame error propagation and the correlation between error frames. The accuracy of the proposed model is validated with JVT/H.264 encoded standard test sequences and previous frame concealment, where the proposed model provides an obvious accuracy gain over previous models.  相似文献   

Effects of environmental intervention on sedentary time,musculoskeletal comfort and work ability in office workers     

Ying Gao  Nina Nevala  Neil J. Cronin  Taija Finni 《European Journal of Sport Science》2016,16(6):747-754

Sit–stand workstations offer a potential strategy to reduce prolonged occupational sitting. This controlled intervention study examined the effects of an environmental intervention on occupational sedentary time, musculoskeletal comfort and work ability, and the usability of sit–stand workstations in office work via a self-reported questionnaire. The intervention group (n?=?24) used sit–stand workstations during the 6-month intervention period, and the control group (n?=?21) used traditional sitting workstations. The results showed that working at sit–stand workstations can reduce sitting time significantly compared to control workstations (?6.7% vs. 5.0%, p?=?.019), which is reallocated mostly to standing (r?=??0.719, p?p?=?.028), as well as work ability (p?=?.022). The majority of intervention subjects rated sit–stand workstation adjustability as good (83.3%), and 75.0% were satisfied with the workstation. About 41.7% of the intervention participants, who were exclusively female, used the sit–stand function on a daily basis. While the environmental change alone was effective, it is likely that promoting the daily use of sit–stand workstations with counselling would lead to even more substantial positive effects.  相似文献

Study on pig growth hormone gene polymorphisms in western meat-type breeds and Chinese local breeds     

宋成义  高波  经荣斌  陶勇  毛九德 《浙江大学学报(A卷英文版)》2003,4(6):734-739

Chinese Meishan and Jiangquhai pigs are two of the most prolific pigs in the world, but their growth rate is lower than that of Duroc, Landrace and Pietrain pigs. It is suggested that growth rate is regulated by growth hormone. The objective of the current study was to analyze the porcine growth hormone (pGH) gene polymorphisms based on the polymerase chain reaction restriction fragment-length polymorphism method (PCR-RFLP) for three western meat-type breeds (Duroc, Landrace and Pietrain) and two local Chinese pigs (Meishan and Jiangquhai). Five polymorphic restriction sites were detected with the ApaI, MspI, BspI and HhaI restriction enzymes in two amplified fragments (605 bp, -119 to +486; 506 bp, +206 to +711). Breed difference was found only in the 506 bp fragment. There was no difference in allelic frequencies of BspI and HhaI restriction sites among the five breeds (P>0.05). Landrace and Meishan pigs lacked allele G3 of MspI site. The allele G3 frequency of restriction MspI site of the 506 bp fragment in Pietrain pigs was higher than that in Duroc and Jianquhai pigs (P<0.001). For ApaI site, the Meishan pigs lacked allele G1; no difference was found in allelic frequencies among Pietrain, Duroc, Landrace and Jiangquhai pigs (P>0.05). This new and rapid PCR-RFLP typing method is an attractive tool for analysis of porcine growth hormone gene restriction sites. The differences in MspI and ApaI restriction sites may explain the growth difference between the foreign meat-type breeds above mentioned and local Chinese pigs.  相似文献
