基于文献计量的国际草地农业生态学研究发展态势分析

草地农业生态学研究体现出生物学、农学和地理学交叉的特点。近年来,全球许多国家及相关研究机构对草地农业生态学的研究力度不断加大。本研究以SCIE论文数据库作为数据源,利用Thomson Data Anlyzer(TDA)和UCINET软件对1996-2015年草地农业生态学研究论文进行数据挖掘和定量分析,探究了近20年来国际草地农业生态学研究的变化趋势、研究力量分布、重点领域、研究热点及国际合作。结果表明,近20年来,国际草地农业生态学研究论文以平均8%的速度增长;草地农业生态学研究所涉及的学科较多,主要有农业、环境科学与生态学、植物科学、生物多样性与保护、地质学等;除了对草地、农业关注外,草地农业生态学研究也对物种及生态环境保护较为重视;美国、英国等发达国家的草地农业生态学研究论文的综合影响力较高,美国在国际间合作中表现最为突出,与各主要国家间均具有很强的合作关系;中国科学院在草地农业生态学研究方面非常活跃,其论文量遥遥领先于法国农业科学研究院、加拿大萨斯喀彻温大学等其他机构,但研究水平、影响力以及国际合作能力仍有待提升。

Reflection on the history,coordination, and funding trends for U.S. public meat research: information to enhance resource allocation

A study was conducted to analyze resource allocation for public meat research in the United States and characterize the portfolio of meat research investments. Trends in the amount of public resources provided for meat research (beef, pork, lamb, and poultry) were analyzed for fiscal years 1980, 1985, 1990, 1995, and 1997. An in-depth analysis was conducted for data from fiscal year 1998 to characterize the profile of the research portfolio. Funding levels and scientist-year equivalents were aggregated to represent the measures of resource allocation for three mutually exclusive research categories: 1) meat quality, 2) food safety, and 3) product development and processing. Data for the 1998 profile analysis were derived from a computer search based on the combination of key words and research classification codes to avoid duplication and cluster research projects. Individual research projects were individually reviewed and a percentage was assigned to four mutually exclusive research categories: 1) meat quality, 2) food safety, 3) product development and processing, and 4) marketing. As meat research evolved over the past century, considerable efforts were expended by researchers and administrators to ensure the coordination of research and program relevance. This is demonstrated by the establishment of numerous multistate research committees. Total funding for meat science increased only modestly when adjusted for inflation during the two decades of this study; however, notable changes occurred in the distribution of resources in the portfolio. Funding for meat quality and product development and processing remained virtually unchanged when adjusted for inflation, whereas funding for food safety increased considerably. The total number of scientists conducting meat research remained virtually unchanged during the period, but the proportion allocated to food safety research increased substantially. The federal portion of total funding decreased from 61.3% to 51.6% between 1980 and 1997, whereas the percentage from both state appropriations and private sources increased. Modifications in research emphasis were influenced by industry problems such as meat quality, public perceptions about food safety, the availability of research funding, scientific advances occurring in molecular biology and genetic manipulation, and the changing meat industry. The information in this paper provides administrators and researchers the opportunity to make better informed decisions about resource allocation for meat research.     

基于CiteSpace的草地鼠害研究现状及热点分析

1950年以来中国学者对苜蓿属的研究：历史脉络与启示

苜蓿自汉朝被引入中国，距今历两千余年，当前已发展成为第一大栽培牧草，相对而言，我国苜蓿研究起步较晚，在近年始得以迅猛发展，但目前对其研究的历史脉络尚未见报道。为此，通过文献计量学的方法，获取 CNKI、WOS 数据库及相关的统计数据的资料，综合分析了1950年以来中国学者对苜蓿的研究轨迹，探究了近65年来成果数量、热点演进、关键节点等，并对比了国内、国际苜蓿研究的发展轨迹。结果表明，1）1950年来，中国学者在苜蓿方面的研究论文数量呈现强劲的增加态势，根据其自然增长特征，可分为5个时期，2000年以后进入极速增长阶段；2）近年来，中国学者对苜蓿研究的国际化程度逐年提高，目前中国已跃居全球第二大苜蓿研究国；3）中国学者最早较为注重对地方品种及其遗传资源的挖掘，近年对高产、优质、抗逆育种与栽培理论的研究较多，更加注重苜蓿产业发展相结合，相比于国外，对分子基础、种间互作等机理性研究尚显不足；4）苜蓿产业的成长、科技期刊的发展、科研项目资助强度的增大是近65年来苜蓿研究得以迅猛发展的重要因素。研究认为，在未来的食物结构转型、草地农业发展等历史趋势下，中国苜蓿研究将会从偏重于产业相关的技术研究，过渡到基础理论研究，从而全方位支撑国家重大战略需求和基础科学理论需要。     

The value of biomedical research training for veterinary anatomic and clinical pathologists

Veterinary pathologists traditionally have been actively engaged in research as principal investigators and as collaborators. Pathologists frequently obtain advanced training in research; however, it appears that in the last 10 years there has been a reversal of a previous trend toward increasing numbers of pathologists obtaining PhD degrees. This has arisen despite an established shortage of veterinarians engaged in research. This article evaluates the benefits of research training for individual pathologists, including a wide spectrum of professional opportunities and additional skill development beyond that usually provided by diagnostic pathology training alone. Various training models are discussed, including combined and sequential diagnostic residency and research degree training as well as the nondegree research fellowship programs more commonly pursued in human medicine. Best-practice recommendations for program infrastructure, mentorship, time management, and a team approach to research and research training are advocated to facilitate the development of successful programs and to encourage a continued emphasis on integrated training for pathologists as both clinical diagnosticians and experimentalists. This article is intended to help prospective and active pathology trainees, their mentors, and educational administrators optimize opportunities to ensure the future vitality of veterinary pathologists, and their contributions, in basic and applied research.     

Epidemiological study of the characteristics of veterinarians who pursue a research career: part I

This retrospective, matched case-control study compared the characteristics of veterinary surgeons employed in veterinary research with those who had never held a research post. The cases were randomly selected from graduates of veterinary schools in Great Britain or Ireland who were employed at universities or institutes that conduct research and who played a major role in veterinary research projects during 2001 to 2003. The controls were veterinary surgeons who had not held any post that was primarily a research post since they graduated. The cases and controls were matched by year of graduation and data were obtained for 173 matched sets. Graduates who were significantly (P<0.05) more likely to have a career involving research included male graduates, graduates who had completed a summer studentship, graduates who had completed an internship, residency or houseman's programme, graduates who held a veterinary diploma, and graduates who had intended to pursue a career in research or academia when they graduated from veterinary school. A career involving research was significantly (P<0.05) more likely to be associated with full-time employment and a lower salary than a career that did not involve research.
