- A hypothesis is a proposition, set forth as an explanation for the occurrence of a phenomenon, that can be tested. - The basis for scientific investigation is the collection of information to formulate and test hypotheses. - Experimental methods measure the effect of manipulations caused by the investigator; observational methods collect information about naturally occurring events. - There are three sub-types of experimental techniques that differ in the way subjects are chosen for inclusion in the study, in the amount of control that the investigator has over variables, and in the method used to assess changes in other variables. - Descriptive observational studies dominate the early phase of most investigations and involve the description of disease-related events in the population. Associations among factors may be observed but the strength of the associations is not measured. - Analytical observation al techniques are of three basic types: prevalence surveys, case:control studies, and incidence or cohort studies. All attempt to explain the nature of relationships among various factors and to measure the strength of associations. - Prevalence surveys and case:control studies deal with disease existing at the time of the study; incidence studies are concerned with the development of disease over time. - Observational studies may be retrospective, using existing data, or prospective with collection of new information.

A respected resource for decades, the Guide for the Care and Use of Laboratory Animals has been updated by a committee of experts, taking into consideration input from the scientific and laboratory animal communities and the public at large. The Guide incorporates new scientific information on common laboratory animals, including aquatic species, and includes extensive references. It is organized around major components of animal use: Key concepts of animal care and use. The Guide sets the framework for the humane care and use of laboratory animals. Animal care and use program. The Guide discusses the concept of a broad Program of Animal Care and Use, including roles and responsibilities of the Institutional Official, Attending Veterinarian and the Institutional Animal Care and Use Committee. Animal environment, husbandry, and management. A chapter on this topic is now divided into sections on terrestrial and aquatic animals and provides recommendations for housing and environment, husbandry, behavioral and population management, and more. Veterinary care. The Guide discusses veterinary care and the responsibilities of the Attending Veterinarian. It includes recommendations on animal procurement and transportation, preventive medicine (including animal biosecurity), and clinical care and management. The Guide addresses distress and pain recognition and relief, and issues surrounding euthanasia. Physical plant. The Guide identifies design issues, providing construction guidelines for functional areas; considerations such as drainage, vibration and noise control, and environmental monitoring; and specialized facilities for animal housing and research needs. The Guide for the Care and Use of Laboratory Animals provides a framework for the judgments required in the management of animal facilities. This updated and expanded resource of proven value will be important to scientists and researchers, veterinarians, animal care personnel, facilities managers, institutional administrators, policy makers involved in research issues, and animal welfare advocates.

Pastoralists make the most of resources distributed unevenly over space and time to provide a range of goods and services. Operating in a shock-prone environment, pastoralists deploy endogenous strategies such as mobility, diversification in agriculture or in non-agricultural activities, management of social networks, etc. However, accurate and reliable knowledge about the economics of pastoralism is yet to be understood and absorbed at the local, regional and national levels, based on reliable data. In the absence of such knowledge, governments and private firms neglect investment that would allow those systems to better connect to markets, and are unable to provide appropriate services, infrastructure and tenure security. With Argentina, Chad and Mongolia as pilot cases, this study by CIRAD, commissioned by FAO, funded by IFAD and facilitated by pastoralist associations (Fundación Gran Chaco, Réseau Billital Maroobé, and the National Federation of Pasture User Groups), aimed to fulfil this knowledge gap through a multifunctional assessment of pastoral production systems and their economic contribution. Importantly, incorporating self-consumption of pastoralist households’ productions themselves as an key component of gross revenue shows a significant increase in their contribution to national GDPs. The diversified sources of revenue and the importance of self-consumption also indicate that pastoral systems fulfil a range of functions (income, food security, flexible labor, etc.). Further, the study promotes close cooperation between pastoralist associations, research institutions and development partners. Such new partnerships allow strengthening the capacity of those pastoralist associations in collecting and managing their own data, as well as using this data in policy dialogue.
