基于GIS与GPS的农牧业资源调查方法初探

利用GIS与GPS技术进行农牧业资源调查已成为近年来的发展趋势。根据GIS的空间数据处理、空间分析功能与GPS的精确空间定位能力,提出了一种基于GIS与GPS集成的农牧业资源调查方法。它集调查点的空间位置信息与属性信息于一体,较好地服务于不同资源的定量、定性分析。以甘肃省庆阳市冬小麦Triticum aestivum调查为例,利用GPS对庆阳市2004年冬小麦播种面积进行实测,并结合地理信息系统(GIS)软件Arc/info和Arcview进行图形编辑和数据处理,准确获得该地区2004年冬小麦种植面积与庆阳市上报的冬小麦种植面积数据接近。

An integrative and case-based approach to the teaching of general and systemic pathology

Since 1993, the pre-clinical phase of the professional (DVM) curriculum at Michigan State University College of Veterinary Medicine has included two pathology courses in which both anatomic and clinical pathologists collaborate to teach concepts in general and systemic pathology. Topics such as inflammation, circulatory disturbances, and neoplasia are taught in this collaborative manner in the year 1 General Pathology course, and pathology of the digestive system (including liver and pancreas), urinary system, and lymphoid system are "team-taught" in the year 2 Clinical and Systemic Pathology course. We feel that this approach gives students an appreciation of the whole-body dynamics of a disease process as it occurs in bone marrow, peripheral blood, body fluids, and tissues and that it leads to a deep understanding of pathologic processes. In addition, the use of "active learning" instructional strategies grounded in case discussions further enhances students' understanding of important concepts by demonstration of practical applications and serves to generate strong interest in learning the subject matter. Integration of concepts of pathology with those taught concurrently in other courses, such as those in physiology and microbiology, is also an important component of pathology instruction in the pre-clinical curriculum.     

Veterinarians teaching at schools of agriculture in Germany (up to 1950)--their contribution to animal nutrition

During the 19th century in Germany mainly veterinarians working at agricultural schools or appointed to veterinary schools from there (for example HAUBNER, ROLOFF, DAMMANN, ALBRECHT, KRONACHER) made considerable contributions to the development of animal nutrition. They disseminated knowledge of feedstuffs and feeding techniques to the interested public at large by books concerning animal husbandry and especially "Gesundheitspflege" (health regimen; Tab. 1). Their experimental work (Tab. 2) extended from digestibility of feedstuffs, Ca-, P- and rumen metabolism (NPN), respectively, to feed intoxications. The interest in preventive measures being stronger at school of agriculture than at veterinary schools probably stimulated this development.

A philosophy and approach to teaching the epidemiology of food-borne, waterborne, and zoonotic diseases

Faculty members from veterinary colleges that teach courses on food-borne, waterborne, and zoonotic diseases to non-veterinary students face unique challenges. The diversity of students' backgrounds, skills, and goals and the public nature of the science require some ingenuity in combining good science with the ability to communicate clearly in a variety of public forums. Drawing on pedagogical theory, the nature of the material, and the diverse abilities of the students, we have put together an effective teaching package for non-veterinary courses on these subjects, which includes a range of methods from outbreak investigations to town hall meetings and food diaries.     

A new approach to teaching veterinary public health at the Ohio State University

Public-health practitioners with expertise in the area of veterinary public health are expected to understand the prevention and control of zoonotic infectious diseases in both human and animal populations. This focus on multiple species is what makes the veterinary public health (VPH) official unique. The development of a new VPH specialization within the existing Master of Public Health (MPH) degree program at the Ohio State University represents a significant new collaboration between the College of Veterinary Medicine and the College of Public Health. The main objective of the VPH specialization is to educate and train professionals to provide them with the skills, knowledge, and resources necessary to protect and improve human health using a One Medicine approach. The program targets a population of students who will likely enter the professional veterinary medicine curriculum but have one year available to enhance their preparatory training in health sciences before beginning the program. A core series of VPH courses was initiated to complement the existing MPH course requirements. The program has been successful in attracting students from the primary target population, but it has also attracted students wanting the MPH as a terminal degree and veterinarians returning to school to expand their career options.     

Sheep farming intensification and utilization of natural resources in a Mediterranean pastoral agro-ecosystem

The research was carried out in the “Sierra y Cañones de Guara” Natural Park, a protected mountain area located in the Central Pyrenees (Huesca, Spain). In this territory, a notorious recession of agricultural activities has been observed in recent decades, which has originated changes in the type and intensity of land utilization and, simultaneously, led to environmental and landscape degradation.The main goal of this research was to analyse what characteristics of the current sheep farming systems could explain different patterns of utilization of the grazing resources. Information was obtained through direct interviews with all sheep farmers that used the grazing resources of the Park in 2000 (n = 53). Specific information on grazing management (grazing areas, grazing periods, number and type of grazing animals) was collected together with data on family characteristics, labour, flock management, land use, continuity, recent changes in farming and farmers opinions. Principal Components Analysis was used to examine relationships among original variables. Farming systems were then characterized in four homogeneous groups using Cluster Analysis. Finally, a Logistic Regression allowed determining relationships between the level of intensification of management and several social and technical features.Intensification of farm management was linked to the type and intensity of land utilization: the higher the intensification of the reproduction system the shorter the grazing period and the lower number of grazing animals. Besides, chances of continuity were critical in some groups of farms, especially in some of the most extensive ones, while many farms with good chances of permanence showed more intensive management strategies but lower utilization of grazing resources. In this type of agro-ecosystems, rural development policies with conservation purposes should focus on farming systems with more environmentally desirable management strategies, and consequently enhance their chances of continuity.
