Some aspects of anthropomorphism in the terminology and philosophy underlying Western and Japanese studies of the social behaviour of non-human primates

Asquith, Pamela J. January 1981 (has links)
This study investigates how anthropomorphism arises in Western and Japanese reports of non-human primate behaviour. Chapter 1 introduces the study and notes that differences in recording styles and incidence of anthropomorphism in Western and Japanese reports led to the thesis that the basis for anthropomorphism differed between the two groups. In Western studies it was found necessary to inquire into philosophical aspects of language use. In Japanese studies the inquiry centred on evidence for the retention of traditional attitudes to nature. Part One focuses on the basis for anthropomorphism in Western studies. Chapter 2 discusses the intellectual basis for the deeply ingrained belief in the West in the separateness of man and animals. The more immediate intellectual background to Western primate studies is traced in chapter 3 through the development of comparative psychology and ethology and then of primatology itself. A more precise formulation of the Western inquiry is developed in chapter h through discussion of ordinary language, distinction between categories of anthropomorphism and between the notions of a subjective approach to study and the ascription of human subjective experiences to animals. Cognitive ethology is briefly described. Chapter 5> identifies the characteristic of language use that gives rise to anthropomorphism as metaphor. Part Two focuses on Japanese studies. Japan had no tradition of objective science and Western science was imported to Japan. This section develops the argument that Western science was adapted to existing Japanese thought and that a traditional intuitive approach to nature and feeling of unity with animals was retained. The development of Japanese primate studies and evidence for the acceptability of anthropomorphism to Japanese primatologists are presented in chapter 6. Certain basic ideas of traditional Japanese views are outlined in chapter 7. The effects of the first small-scale importation of Western science on the Neo-Confucian precepts of Tokugawa Japan are traced in chapter 8. The way in which especially biology was understood in the subsequent major importation of science to Meiji Japan is examined in chapter 9. The methodology of the Japanese primatologists is examined in chapter 10 and newly translated material showing the application of traditional Japanese thought to primatology is presented. Other new material on the origins of the focus on personality and culture in monkey groups is given. The application of traditional Japanese ideas of nature to their methodology and the use of a socioanthropological framework for explanation of observed behaviour is seen to be compatible with anthropomorphism in the Japanese studies. Chapter 11 summarizes the course of the study and discusses what conclusions may be drawn.

Gene Conversions in the Siglec and CEA Immunoglobulin Gene Families of Primates

Zid, Mouldi 10 January 2013 (has links)
Siglecs and CEA are two families of cell surface proteins belonging to the immunoglobulin superfamily. They are thought to be involved in cell-cell interactions and have various other biological functions. We used the GENECONV program that applies statistical tests to detect gene conversion events in each family of five primate species. For the Siglec family, we found that gene conversions are frequent between CD33rSiglec genes, but are absent between their conserved Siglec genes. For the CEA family, half of gene conversion events detected are located in coding regions. A significant positive correlation was found between the length of the conversions and the similarity of the converted regions only in the Siglec gene family. Moreover, we found an increase in GC-content and similarity in converted regions compared to non-converted regions of the two families. Furthermore, in the two families, gene conversions occur more frequently in the extracellular domains of proteins, and rarely in their transmembrane and cytoplasmic regions. Finally, these two families appear to be evolving neutrally or under negative selection.

What Meaning Means for Same and Different: A Comparative Study in Analogical Reasoning

Flemming, Timothy M 04 December 2006 (has links)
The acquisition of relational concepts plays an integral role and is assumed to be a prerequisite for analogical reasoning. Language and token-trained apes (e.g. Premack, 1976; Thompson, Oden, and Boysen, 1997) are the only nonhuman animals to succeed in solving and completing analogies, thus implicating language as the mechanism enabling the phenomenon. In the present study, I examine the role of meaning in the analogical reasoning abilities of three different primate species. Humans, chimpanzees, and rhesus monkeys completed relational match-to-sample (RMTS) tasks with either meaningful or nonmeaningful stimuli. For human participants, meaningfulness facilitated the acquisition of analogical rules. Individual differences were evident amongst the chimpanzees suggesting that meaning can either enable or hinder their ability to complete analogies. Rhesus monkeys did not succeed in either condition, suggesting that their ability to reason analogically, if present at all, may be dependent upon a dimension other than the representational value of stimuli.

Hepatitis B Virus in Silvery Gibbons (Hylobates moloch)

karen.payne@perthzoo.wa.gov.au, Karen Louise Payne January 2004 (has links)
This research investigated a number of issues regarding hepatitis B virus (HBV) in the silvery gibbon (Hylobates moloch). Due to the relatively recent discovery of the virus in nonhuman primate populations, specific knowledge of the biological behaviour of the virus is presently lacking, with current information largely extrapolated from the behaviour of HBV in human infections. In order to manage the captive and wild populations of this critically endangered species, information regarding the behaviour of the virus in gibbons and the likely impact of the viral infection is essential. The research was performed at Perth Zoo, with the study population consisting of the current and historical members of the zoo’s silvery gibbon colony. Because this gibbon species is critically endangered, the study was conducted with minimal intervention to the population with samples collected largely on an opportunistic basis from a small study population. Review of the history of the virus within the Perth Zoo colony provided epidemiological evidence to indicate vertical transmission in three gibbons (Hecla, Uban and Jury). It would appear that vertical transmission is the primary mode of transmission leading to dispersal of the virus through the captive population of silvery gibbons. Elevated concentrations of the liver enzymes alanine aminotransferase and aspartate aminotransferase were found in three gibbons (Perth 2, Uban and Jury), and may suggest a pathogenic role of the virus in this species. Histological examination of the livers of Uban and Perth 2 failed to demonstrate definitive evidence of cirrhosis, however mild fibrosis was seen in both cases and may represent an early stage of liver pathology associated with chronic hepatitis B infection. The vaccination protocol developed at Perth Zoo was successful in preventing neonatal transmission of the virus from a high infectivity carrier mother in at least two individuals, and was also successful in producing a protective level of immunity against the virus in all three of the individuals tested. Sequencing of the complete hepatitis B genome from one gibbon (Hecla) revealed that she was infected with GiHV (Gibbon hepatitis B virus), an indigenous strain of HBV previously identified in a number of gibbon species, but not previously confirmed in the silvery gibbon. Hecla's strain of HBV was shown to be more closely related to other nonhuman primate strains of HBV than to any of the human strains of HBV. 100% nucleotide similarity to two of Hecla’s siblings indicates that infection in all three animals was the result of vertical transmission from their mother. Partial sequencing of the virus from a second gibbon (Uban) identified another strain of GiHBV which supports the results of the epidemiological study. Neither gibbon showed a high sequence similarity to the virus sequenced from Ivan, the father of the third carrier gibbon (Jury), although only limited sequence data was available from Ivan. Consequently it is likely that at least three different strains of GiHBV are present within the silvery gibbon population. The information contained in this thesis will assist in the understanding and management of hepatitis B infection in silvery gibbons, as well as the numerous other species of nonhuman primates now shown to be susceptible to this virus.
