【摘要】 为了使预防兽医学科的科研人员对科学论文的投向有更深入的了解,同时,使预防兽医及其相关学科期刊的办刊人员对提高自身期刊影响因子有所借鉴,对预防兽医学及其相关学科的期刊有关数据指标进行了分析统计,以探讨这些指标与期刊影响因子之间的关系。 将10种期刊按照不同学科分成四组,《微生物学报》和《病毒学报》为一组,《中国免疫学杂志》、《免疫学杂志》和《上海免疫学杂志》为二组,《水产学报》和《中国水产科学》为三组,《中国兽医学报》、《畜牧兽医学报》和《畜牧与兽医》为四组。采用文献计量学方法分别统计各期刊2000-2002年度的总被引频次和1998-2002年度各期刊的影响因子、载文量(number of articles published)、发表周期、基金论文比、总参考文献量、平均引文率(mean reference rate)、中外文文献比。对每项指标在不同学科之间、同一学科不同期刊之间进行比较,并进行显著性检验,研究它们与影响因子的一致性。观察影响因子与其他指标变化趋势的符合程度及关系。通过相关分析研究各个期刊上述指标与影响因子是否有相关性,及其相关性的大小。 对上述10种期刊306期杂志的论文进行研究。结果载文量共为6228篇;发表周期共为77625个月;省部级以上基金项目资助的论文数达3489篇,占论文总数的56.02%,基金论文比为0.560;引用参考文献的总量为63490条,平均引文率为10.194条/篇。其中引用中文参考文献20868条,占参考文献总数的32.87%,外文参考文献42622条,占参考文献总数的67.13%,中外文文献比为0.491。 不同学科、不同期刊之间影响因子有较大的差别。按学科不同其影响因子从大到小依次顺序为:一组、三组、二组、四组。10种期刊平均影响因子从大到小的依次顺序为:《病毒学报》、《水产学报》、《微生物学报》、《中国免疫学杂志》、《上海免疫学杂志》、《免疫学杂志》、《中国水产科学》、《中国兽医学报》、《畜牧兽医学报》、《畜牧与兽医》。 对载文量的研究结果表明,《微生物学报》高于《病毒学报》(P<0.01),《中国水产科学》高于《水产学报》(P>0.05),《畜牧与兽医》高于《畜牧兽医学报》(P<0.01),与它们影响因子高低正相反。《中国免疫学杂志》和《免疫学杂志》年均载文量增加幅度较大,它们的影响因子下降幅度也较大。《水产学报》年均载文量增加幅度小,影响因子下降幅度也小。载文量与影响因子的变化趋势相反。二者相关分析结果也证明,载文量与影响因子存在着显著的负相关(r=-0.570 P<0.05)。 影响因子较高的期刊发表周期均相对较长。一组和三组平均发表周期较二组和南京农业大学兽医专业学位论文四组长,其影响因子也较高。在8对期刊中,有3对期刊的发表周期间差异的显著性与影响因子间差异的显著性一致。10种期刊发表周期总的呈下降趋势。影响因子与发表周期总的变化趋势没有明显的关系。相关分析表明,影响因子与发表周期之间存在着较弱的正相关关系(厂二0.406),但差异不显著(乃0.05)o 基金论文比均值一组最高,其次为三组,这两组期刊的影响因子也高于另外两组。除一组的两种期刊外,其他三个组期刊间基金论文比的大小,均与影响因子的高低相一致。各期+lJ基金论文比均呈现上升态势,《微生物学报》和《水产学报》的基金论文比与其本身影响因子的变化趋势一致。相关分析结果表明,基金论文比与影响因子之间存在着显著的正相关关系(厂二0 .614 P<0.肠)o 一组和三组平均引文率大于另外两组;《病毒学报》平均引文率最大,《畜牡与兽医》最小,与它们影响因子的大小情况一致。在8对期刊中,4对期刊平均引文率的大小情况及差异显著性检验结果与影响因子一致。6种期刊的平均引文率与其本身的影响因子的变化趋势相同或者相似,2种有部分相似。相关分析结果证明,平均引文率与影响因子之间具有较强的正相关(厂二。.710),且差异极显著(P<0 .01)o 中外文文献比((微生物学报》大于《病毒学报》,并且差异极显著(P<0 .01),《畜枚与兽医》大于另外两种期刊,并且差异显著(P<0 .05),((中国水产科学》大于《水产学报》,但差异不显著(外。.05),这些与他们之间影响因子的大小相反。10种期刊中有7种期刊呈下降趋势,说明多数期刊引用外文文献的比例有所增加,《中国水产科学》下降的幅度最大,而其影响因子上升的幅度也最大;中外文文献比与影响因子的变化趋势不同。相关分析结果表明,二者之间存在着较弱的负相关(厂二一0 .407外0 .05)。 各期刊间总参考文献量比较以及其影响因子间的比较结果表明,在8对期刊里,有4对期刊中每对期刊间总参考文献量的大小及其差异的显著性,分别与各自影响因子的大小及其显著性一致,其余配对期刊不一致。各期刊总参考文献量与影响因子的变化趋势不一致,并且没有明显的联系。相关分析结果也表明,总参考文献量与影响因子间不相关(厂二0.112外0.05)o 通过上述研究结果可以得出以下结论:被引频次是期刊影响因子的决定因素。平均引文率、基金论文比、载文量对影响因子的影响作用较大,发表周期、中外文文献比对影响因子的影响
【Abstract】 Some indexes on preventive veterinary medicine and its related disciplines were analyzed to explore their relations with IF. It would be of benefit to the researchers in this field to deliver their articles and to the periodicals-makers to improve IF of their periodicals.Ten periodicals were categorized into four groups: << Journal of Microbiology> and << Journal of Virology> as the first group, <<Chinese Journal of Immunology> ,<<Journal of Immunology> and<<ShangHai Journal of Immunology > as the second, <<Chinese Journal of Fishery> and <<Chinese Journal of Fishery Science> as the third, <<Chinese Journal of Veterinary Science>, <<Chinese Journal of Animal Husbandry and Veterinary Science> and <<Journal of Animal Husbandry & Veterinary Medicine> as the fourth. Some indexes, including times of citation from 2000 to 2002 , IF from 1998 to 2002 , number of articles published , publishing period , ratio of funded papers , total numbers of references , mean reference rate and ratio between Chinese and foreign reference, were analyzed respectively. And each of them, comparisons was made among different disciplines or different issues of the same periodical using significance test. By statistical analysis, the conformability of change tendency in these indexes with that in IF could be researched.Based on 306 issues of ten periodicals, following results were concluded: Number of articles published was 6228. Total publishing period was 77625 months. Number of papers funded by province and ministry was 3489 covering 56.02%. Ratio of papers sponsored by foundation was 0.560. Total number of reference cited was 63490 with 20868 in Chinese, covering 32.87% and 42622 in foreign, covering 67.13%. The mean reference rate was 10.194 per paper.Fairly greater distinctions among IF of different periodicals existed. By groups, first group ranked first, next the third group, then the second and finally the fourth. By periodicals and their IF, the turn was as the follows: <<Journal of Virology >,<< Chinese Journal of Fishery >,<< Journal of Microbiology >,<<Chinese Journal of Immunology>, <<ShangHai Journal of Immunology>,<<Journal of Immunology>,<<Chinese Journal of Fishery Science>,<< Chinese Journal of Veterinary Science >,<<Journal of Animal Husbandry & Veterinary Medicine> and <<Chinese Journal of Animal Husbandry & Veterinary Science>.In the aspect of number of articles published, <<Journal of Microbiology> was higher than<< Journal of Virology > (JP<0.01). { Chinese Journal of Fishery Science ) was higher than <<Chinese Journal of Fishery>( P>.05), but they were on the contrary in IF aspect. It was found that there was a negative association between number of articles published and IF (r = - 0.570 /><0.05 ) .Concerned with IF and publishing period, no significant association was found though there was aweak correlation ( r = 0.406, P>0.05 ) . Specifically, 3 in 8 pairs of periodicals were consistent in both indexes; group 1 and group 3 were longer in publishing period and higher in IF than group 2 and group 4. Publishing period of 10 periodicals was in a drop tendency and periodicals with higher IF had longer publishing period.By the analysis of ratio of funded paper and IF, it was found two indexes were in significant association with each other (r = 0.614 P<0.05) . Except two periodicals in group 1, the index relatives in the others conformed to this trend .There was a very significant association (r = 0.710 P<0.01 )between mean reference rate and IF, with 4 in 8 pairs of periodicals consistent, 6 kinds of periodicals same or similar and 2 partially similar. Mean reference rate in group 1 and group 3 were greater, with (Journal of Virology) the greatest and ( Journal of Animal Husbandry & Veterinary Medicine } the smallest.In case of two indexes ratio of Chinese and foreign reference and IF, their association was weak (r - - 0.407 P>0.05) . Among all the periodicals, 7 periodicals decrease in ration of Chinese and foreign references but increase in IF, especially { Chinese Journal of Fishery Sci
