The concept of natural behavior is a key element in current Dutch policy-making on animal welfare. It emphasizes that animals need positive experiences, in addition to minimized suffering. This paper interprets the concept of natural behavior in the context of the scientific framework for welfare assessment. Natural behavior may be defined as behavior that animals have a tendency to exhibit under natural conditions, because these behaviors are pleasurable and promote biological functioning. Animal welfare is the quality of life as perceived (...) by the animal. Animals have evolved cognitive-emotional systems (“welfare needs”) to deal with a variable environment. Animals do not only have so-called physiological needs such as the need for food, water, and thermal comfort. They also need to exercise certain natural behaviors such as rooting or nest-building in pigs, and scratching or dust-bathing in poultry. All needs must be taken into account in order to assess overall welfare. The degree of need satisfaction and frustration can be assessed from scientific information about the intensity, duration, and incidence of (welfare) performance criteria such as measurements of behavior and/or (patho)physiology. Positive welfare value relates to how animals are inclined to behave under natural conditions, in preference tests, and in consumer-demand studies. Negative welfare value relates to stress, frustration, abnormal behavior, aggression, and reduced fitness. Examples are given to illustrate how the need to perform natural behaviors can be assessed following the general principles for welfare assessment, providing a first approximation of how different natural behaviors affect animal welfare.

Günümüze kadar süregelen bir mezhep olarak Zeydiliğin Yemen bölgesinde geçirdiği süreçlerden birisi de 16. yy.’da imametini ilan eden Mansûr-Billâh Kâsım b. Muhammed ile başlayan ve Cumhuriyetin ilanına kadar iktidarın soyundan gelenlerin devam ettirdiği dönem bulunmaktadır. Ancak Kâsımîler dönemi olarak bilinen bu sürece dair literatürde yeterli bilgi bulunmamaktadır. Mansûr-Billâh Kâsım b. Muhammed’in akaid, fıkıh, usul gibi alanlarda kıymetli eserlerinin yanı sıra kaleme aldığı ufak bir risalesi de bulunmaktadır. Bu çalışmada ise Kâsımî Hanedanlığının kurucusu olarak bilinen Mansûr-Billâh Kâsım b. Muhammed’in oğlu Müeyyed-Billâh (...) Muhammed b. Kâsım için kaleme aldığı vasiyet metninin literatüre kazandırılması amaçlanmaktadır. (shrink)

Continued concern for animal welfare may be alleviated when welfare would be monitored on farms. Monitoring can be characterized as an information system where various stakeholders periodically exchange relevant information. Stakeholders include producers, consumers, retailers, the government, scientists, and others. Valuating animal welfare in the animal-product market chain is regarded as a key challenge to further improve the welfare of farm animals and information on the welfare of animals must, therefore, be assessed objectively, for instance, through monitoring. Interviews with Dutch (...) stakeholder representatives were conducted to identify their perceptions about the monitoring of animal welfare. Stakeholder perceptions were characterized in relation to the specific perspectives of each stakeholder. While producers tend to perceive welfare from a production point of view, consumers will use visual images derived from traditional farming and from the animals’ natural environments. Scientists’ perceptions of animal welfare are affected by the need to measure welfare with quantifiable parameters. Retailers and governments (policy makers) have views of welfare that are derived from their relationships with producers, consumers, non-governmental organizations (NGOs), and scientists. All interviewed stakeholder representatives stated that animal welfare is important. They varied in the extent to which they weighted economic considerations relative to concern for the animals’ welfare. Many stakeholders emphasized the importance of communication in making a monitoring system work. Overall, the perspectives for the development of a sustainable monitoring system that substantially improves farm animal welfare were assessed as being poor in the short term. However, a reliable system could be initiated under certain conditions, such as integrated chains and with influential and motivated stakeholders. A scheme is described with attention points for the development of sustainable monitoring systems for farm animal welfare in the long term. (shrink)

The question of the role of science in the development of our society, and the role of the social sciences in particular, loomed large in the decisions of the 23rd Congress of the CPSU. This was a consequence of the tasks posed by the present stage of the building of communism. The proceedings and decisions of the Congress emphasized the rapid advance of science, its increasing influence upon all aspects of the material and intellectual life of society, and the need (...) to assure high rates of scientific and technological progress on the basis of the growth of all branches of knowledge and the extensive introduction of the achievements of science into industry. In the Report of the Central Committee of the CPSU to the Congress, considerable attention was given to the social sciences, upon which the party is now placing even greater responsibility. "The elaboration of important problems in economics and politics, philosophy and sociology, history and law, and in other social sciences, in close association with the practical work of the building of communism," said L. I. Brezhnev, "is a most important task for Soviet scholars." Further, he emphasized: "The development of the social sciences and the introduction of their recommendations in practice play no less important a role than the employment of the achievements of the natural sciences in the sphere of material production and the development of the intellectual life of the people" . These statements call for thorough consideration. (shrink)
