Bibliographic data can be used to map the research quality and productivity of a discipline. We hypothesized that bibliographic data would identify geographic differences in research capacity, species specialization, and interdisciplinary relationships within the veterinary profession that corresponded with demographic and economic indices.
Using the SCImago portal, we retrieved veterinary journal, article, and citation data in the Scopus database by year (1996-2011), region, country, and publication in species-specific journals (food animal, small animal, equine, miscellaneous), as designated by Scopus. In 2011, Scopus indexed 165 journals in the veterinary subject area, an increase from 111 in 1996. As a percentage of veterinary research output between 1996 and 2010, Western Europe and North America (US and Canada) together accounted for 60.9% of articles and 73.0% of citations. The number of veterinary articles increased from 8815 in 1996 to 19,077 in 2010 (net increase 66.6%). During this time, publications increased by 21.0% in Asia, 17.2% in Western Europe, and 17.0% in Latin America, led by Brazil, China, India, and Turkey. The United States had the highest number of articles in species-specific journals. As a percentage of regional output, the proportion of articles in small animal and equine journals was highest in North America and the proportion of articles in food animal journals was highest in Africa. Based on principal component analysis, total articles were highly correlated with gross domestic product (based on World Bank data). The proportion of articles in small animal and equine journals was associated with gross national income, research and development, and % urban population, as opposed to the proportion of food animal articles, agricultural output, and % rural population. Co-citations linked veterinary medicine with medicine in the United States, with basic sciences in Eastern Europe and the Far East, and with agriculture in most other regions and countries.
Bibliographic data reflect the demographic changes affecting veterinary medicine worldwide and provide insight into current and changing global research capacity, specialization, and interdisciplinary affiliations. A more detailed analysis of species-specific trends is warranted and could contribute to a better understanding of educational and workforce needs in veterinary medicine.
文献计量数据可用于描绘学科的研究质量和生产力。我们假设文献计量数据将识别兽医领域内与人口统计学和经济指数相对应的研究能力、物种专业化和跨学科关系的地理差异。
使用 SCImago 门户，我们通过年份（1996-2011 年）、地区、国家和在 Scopus 数据库中以物种为特定目标的期刊（食品动物、小动物、马科动物、杂项）检索了兽医期刊、文章和引文数据，Scopus 对这些期刊进行了指定。2011 年，Scopus 在兽医学科领域索引了 165 种期刊，比 1996 年的 111 种有所增加。在 1996 年至 2010 年期间，西欧和北美（美国和加拿大）的兽医研究成果占文章的 60.9%和引文的 73.0%。兽医文章的数量从 1996 年的 8815 篇增加到 2010 年的 19077 篇（净增 66.6%）。在此期间，亚洲的出版物增长了 21.0%，西欧增长了 17.2%，拉丁美洲增长了 17.0%，其中巴西、中国、印度和土耳其领先。美国在特定物种期刊中的文章数量最多。按区域产出的百分比计算，北美小型动物和马科动物期刊的文章比例最高，非洲的食品动物期刊的文章比例最高。基于主成分分析，总文章与国内生产总值（基于世界银行数据）高度相关。小型动物和马科动物期刊文章的比例与国民总收入、研发和城市人口百分比有关，而不是与食品动物文章、农业产出和农村人口百分比有关。共同引用将兽医与美国的医学联系起来，与东欧和远东的基础科学联系起来，与大多数其他地区和国家的农业联系起来。
文献计量数据反映了影响全球兽医的人口统计学变化，并提供了对当前和不断变化的全球研究能力、专业化和跨学科联系的深入了解。需要更详细地分析特定物种的趋势，这可能有助于更好地了解兽医教育和劳动力需求。
