Older people's relationships with companion animals : a pilot study

When older people enter residential care facilities, disruption to social networks may occur, with detrimental effects on health and wellbeing. This article reports on a study undertaken in an aged care facility in Melbourne, Australia, that explored the potential for a visiting companion animal programme to improve the health and wellbeing of residents and to promote their capacity for building relationships. Results back assertions in the literature that companion animals foster relationships by giving people opportunities to interact with others, but further study is needed to verify the link

Speaking to animals: Japan and the welfare of companion animals

This paper examines the phenomenal popularity of companion animals in Japan, and the way many of these pets are treated as part of the owner’s family. Indeed, some pets are treated as if they are human children. This pet phenomenon was made possible because the Japanese developed a way of seeing their companion animals in anthropomorphic terms, more similar than different to humans. First, this paper describes how this notion has its roots in the Japanese receptivity to the idea that humans and animals can communicate with one another, and the folkloric belief that animals can assume human form and speak. Second, the article details how these ideas and beliefs were consistent with both major Japanese religions, and were sustained in the 20th century by literature and, most recently, anthropomorphic characters in anime and advertising. Finally, the paper argues that there is an anthropomorphic paradox in Japan, whereby the identification of companion animals as possessing human qualities leads to the mistreatment of animals rather than an ethically superior response to animal welfare. While animals benefit materially from being thought of in human terms, being well fed and given the best veterinary care, paradoxically, they can lead miserable lives. Being wheeled in baby strollers and being dressed in designer clothes means that pets have their instincts curbed, and raises questions about the ethics of animal ownership.

The importance of pet loss and some implications for services

Understanding the meaning of companion animals and their loss in peoples' lives has major implications for the way professional services are organized and delivered. There is much research and literature which argues for the major social, emotional and physical benefits of animal companionship, and the widespread nature of pet ownership. Yet ironically, much of the professional service literature has tended to marginalize or pathologize the human-animal bond, often dichotomizing it against human relationships and assuming its inferiority. We argue that this reflects a tendency to individualize what should be a major social concern. Therefore service design and delivery needs to reflect a recognition of human-animal relationships as a significant part of normal experience. Services and policies need to factor in both the inclusion and loss of these.

Nature and health

This chapter aims to demonstrate that the natural environment is a key determinant of human health. Natural environments are defined as organic environments where the majority of ecosystem processes are present (e.g. the cycle of life and death, reproduction, relationships between species). Including a spectrum of different environments ranging from wilderness areas in National Parks to farms, and human constructed gardens, 'natural' does not necessarily mean unaffected by human intervention. 'Nature' can also refer to any single element of the natural environment (such as plants, animals, soil and water), including domestic and companion animals as well as cultivated plants. The term 'natural environment' differs from the more usual use of the term 'environment' in that it can be a setting in itself, or it can be an element of other settings, including our homes, workplaces and schools.

Sequence type 131 fimH30 and fimH41 subclones amongst escherichia coli isolates in Australia and New Zealand

The clonal composition of Escherichia coli causing extra-intestinal infections includes ST131 and other common uropathogenic clones. Drivers for the spread of these clones and risks for their acquisition have been difficult to define. In this study, molecular epidemiology was combined with clinical data from 182 patients enrolled in a case-control study of community-onset expanded-spectrum cephalosporin-resistant E. coli (ESC-R-EC) in Australia and New Zealand. Genetic analysis included antimicrobial resistance mechanisms, clonality by DiversiLab (rep-PCR) and multilocus sequence typing (MLST), and subtyping of ST131 by identification of polymorphisms in the fimH gene. The clonal composition of expanded-spectrum cephalosporin-susceptible E. coli and ESC-R-EC isolates differed, with six MLST clusters amongst susceptible isolates (median 7 isolates/cluster) and three clusters amongst resistant isolates, including 40 (45%) ST131 isolates. Population estimates indicate that ST131 comprises 8% of all E. coli within our population; the fluoroquinolone-susceptible H41 subclone comprised 4.5% and the H30 subclone comprised 3.5%. The H30 subclone comprised 39% of all ESC-R-EC and 41% of all fluoroquinolone-resistant E. coli within our population. Patients with ST131 were also more likely than those with non-ST131 isolates to present with an upper than lower urinary tract infection (RR=1.8, 95% CI 1.01-3.1). ST131 and the H30 subclone were predominant amongst ESC-R-EC but were infrequent amongst susceptible isolates where the H41 subclone was more prevalent. Within our population, the proportional contribution of ST131 to fluoroquinolone resistance is comparable with that of other regions. In contrast, the overall burden of ST131 is low by global standards.

Dietary niche overlap of free-roaming dingoes and domestic dogs: the role of human provided food

As both companion animals and opportunistic predators, dogs (Canis lupus spp.) have had a long and complex relationship with humans. In Australia, the dingo (C. l. dingo) was introduced 4,000 years ago and, other than humans, is now the continent's top mammalian predator. Domestic dogs (C. l. familiaris) were introduced by Europeans more recently and they interbreed with dingoes. This hybridization has caused growing concern about the roles that domestic dogs and dingoes play in shaping ecosystem processes. There is also considerable debate about whether anthropogenic environmental changes can alter the ecological roles of dingoes. We used scat analysis to test whether the dingo, as the longer-established predator, occupies a different dietary niche from that of free-roaming domestic dogs, irrespective of human influence. Our results demonstrate considerable dietary overlap between dingoes and domestic dogs in areas where humans provide supplementary food, providing evidence against our hypothesis. However, the consumption by dingoes of a greater diversity of prey, in association with historical differences in the interactions between dingoes and humans, suggests a partial separation of their dietary niche from that of domestic dogs. We conclude that anthropogenic changes in resource availability could prevent dingoes from fulfilling their trophic regulatory or pre-European roles. Effective management of human-provided food is therefore required urgently to minimize the potential for subsidized populations of dingoes and domestic dogs to negatively affect co-occurring prey.

Companion animal visitation and its effectiveness with stroke patients

The study employed a randomised controlled trial design to determine whether a companion animal intervention had any effect on wellbeing and quality of life in patients who were admitted to hospital after suffering a stroke. The study found significant benefits for their wellbeing and improvements in quality of life.

The development of a screening questionnaire for childhood cruelty to animals

Childhood cruelty to animals may be a marker of poor prognosis amongst conduct disordered children. However, other than semistructured interviews with parents or children, there are no screening instruments for this behavior. The aim of this study was to develop such an instrument. In the first phase of the study, a parent-report questionnaire, Children's Attitudes and Behaviors Towards Animals (CABTA) was designed and piloted on 360 elementary school children, enabling community norms and a factor structure for the instrument to be derived. In the second phase, the questionnaire was completed by the parents of a small sample of children (N= 17) to establish its test-retest reliability. In the third phase of the study, the CABTA was completed by the parents of 19 children who had been diagnosed with either a Disruptive Behavioral Disorder or Attention Deficit Hyperactivity Disorder, and the results were compared with the outcome of a semistructured interview with parents regarding their child's behavior toward animals. The results of the various phases of the study indicated that the CABTA consists of two factors, Typical and Malicious Cruelty to animals, and is a reliable and valid tool for detecting childhood cruelty to animals. Possible use and adaptations of the CABTA as a screening instrument in clinical and community samples are discussed.

The relationship between childhood cruelty to animals and psychological adjustment : a Malaysian study

In Western research, cruelty to animals in childhood has been associated with comorbid conduct problems and with interpersonal violence in later life. However, there is little understanding of the etiology of cruelty to animals, and what in the child's life may require attention if the chain linking animal cruelty and later violence is to be broken. The study reported in this paper investigated the association between parent-reported cruelty to animals, and parent- and self-reported psychological strengths and weaknesses in a sample of 379 elementary school children in an Eastern context, Malaysia. No gender differences were found in relation to cruelty to animals or psychological problems, as assessed with the Strengths and Difficulties Questionnaire (SDQ). However, there were different predictors of cruelty to animals for boys and girls. Regression analyses found that for boys, parent-reported hyperactivity was a unique predictor of Malicious and Total Cruelty to animals. For girls, self-reported conduct problems was a unique predictor of Typical Cruelty to animals. Parent-reported total difficulties were associated with Typical, Malicious, and Total Cruelty to animals. We suggest that routine screening of children with an instrument such as the SDQ may help to detect those children who may need to undergo further assessment and perhaps intervention to break the chain linking childhood cruelty to animals and later conduct problems.

Childhood cruelty to animals : a tri-national study

Childhood cruelty to animals is a symptom of conduct disorder that has been linked to the perpetration of violence in later life. Research has identified several factors associated with its etiology, including social factors. However, no cross-cultural studies on this phenomenon have been reported. This study investigated childhood cruelty to animals in Japan, Australia and Malaysia. Parents of 1,358 children between the ages of 5 and 13 years completed the Children’s Attitudes and Behaviours towards Animals questionnaire (CABTA) which assesses Typical and Malicious Cruelty to animals. Analyses revealed no overall differences between children from these countries on either scale. However, younger boys were more likely to be cruel than younger girls in each country, and younger children in Australia and Japan were more likely to be cruel that older children in those countries. The findings are discussed in relation to previous research, and recommendations for future studies are suggested.

Life and death : metabolic rate, membrane composition, and life span of animals

Maximum life span differences among animal species exceed life span variation achieved by experimental manipulation by orders of magnitude. The differences in the characteristic maximum life span of species was initially proposed to be due to variation in mass-specific rate of metabolism. This is called the rate-of-living theory of aging and lies at the base of the oxidative-stress theory of aging, currently the most generally accepted explanation of aging. However, the rate-of-living theory of aging while helpful is not completely adequate in explaining the maximum life span. Recently, it has been discovered that the fatty acid composition of cell membranes varies systematically between species, and this underlies the variation in their metabolic rate. When combined with the fact that 1) the products of lipid peroxidation are powerful reactive molecular species, and 2) that fatty acids differ dramatically in their susceptibility to peroxidation, membrane fatty acid composition provides a mechanistic explanation of the variation in maximum life span among animal species. When the connection between metabolic rate and life span was first proposed a century ago, it was not known that membrane composition varies between species. Many of the exceptions to the rate-of-living theory appear explicable when the particular membrane fatty acid composition is considered for each case. Here we review the links between metabolic rate and maximum life span of mammals and birds as well as the linking role of membrane fatty acid composition in determining the maximum life span. The more limited information for ectothermic animals and treatments that extend life span (e.g., caloric restriction) are also reviewed.
