Testing the Roles of Intergroup Anxiety and Inclusion of Animals in the Self as Mechanisms that Underpin the “Pets as Ambassadors” Effect

It has been suggested that pets provide the opportunity for humans to develop more positive attitudes and relationships toward a wider range of animal types—including toward non-pet animals—this is called the “pets as ambassadors” hypothesis. In this study, we build both on research conducted on human–animal relations and in social psychology to investigate the hypothesis, as well as two likely mechanisms involved in this effect: inter- group anxiety (toward animals) and inclusion of animals in the self. An online questionnaire was completed by 238 Canadian participants (M = 28.6 years old, SD = 8.53; 102 women). Using structural equation modeling (SEM), we tested a model whereby contact with pets predicted greater inclusion of ani- mals in the self and lower intergroup anxiety toward animals in general. In turn, these two psychological processes predicted more positive attitudes toward a broad range of animal types (e.g., wild/pest animals, animals used for human purposes) and animals in general. Finally, these positive attitudes toward animals predicted more pro-social behavioral intentions toward animals. The hypothesized model showed a good fit. Bootstrapping analyses further con- firmed the mediating roles of inclusion of animals in the self and intergroup anxiety toward animals in the associations between contact with pets and attitudes toward animals in general. The hypothesized model also presented a more satisfactory fit compared with an alternative model. Altogether, these findings underline the importance of contact with pets in fostering more positive human–animal relations and promoting animal welfare. These results also support the applicability of social psychological theories and principles in the realm of human–animal relations.     

Does Human–Animal Similarity Lower the Need to Affirm Humans’ Superiority Relative to Animals? A Social Psychological Viewpoint

This research integrates different social psychological theories to test whether human–animal similarity promotes affiliation with animals and lowers the need to affirm humans’ superiority relative to animals. On the basis of theories of intergroup relations, terror management theory, and work conducted in the field of human–animal relations, we expected that higher human–animal similarity would decrease the need to affirm humans’ superiority relative to animals, by triggering a greater sense of shared social identity. Two correlational studies (ns = 187 and 191) tested a mediation model whereby perceived human–animal similarity was expected to predict a lower need to differentiate the perceived status of humans from animals through a process of social identification with animals. Mediated regressions provided support for these associations. A repeated-measures experiment (n = 176) replicated these findings by systematically comparing objectively (phylogenetically) more vs. less similar animals and assessing perceived status and identification. Results are discussed in light of theories of intergroup relations, terror management theory, as well as recent advances in the field of social psychology and self and identity processes.     

Relationships between aggression and pubertal increases in testosterone: A panel analysis of adolescent males

Abstract

Existing data linking testosterone (T) and aggression in human adult males are surprisingly tenuous. In one of the few studies based on adolescent males, Olweus et al. (1988) demonstrated strong relationships between concurrent measures of T and aggression. However, the conclusions that could be drawn regarding developmental change were limited. Using data from a three‐year panel study of 100 adolescent males (ages 12 to 13 at study entry), we examined whether there are significant relationships between concurrently collected measures of T and self‐ratings of aggression, and whether the dramatic pubertal rise in T predicts subsequent change in aggression ratings. Panel analyses incorporating concurrent, lagged, and change measures found few significant relationships between aggression and T or pubertal development. The general absence of T/aggression relationships is discussed in the context of other empirical findings, the aggression measures used, and prepubertal differentiation on aggression.     

Assistance dog placement in the pediatric population: Benefits,risks, and recommendations for future application

Abstract

Assistance animals have long been recognized for their value in enhancing the lives of adults with disabilities by increasing the physical independence, confidence, and social lives of their handlers. Recently, this concept has been applied to the growing population of children with physical disabilities and developmental impairments, though the benefits and risks of these placements have not been thoroughly assessed. Our study used interviews to evaluate the outcome of placing assistance dogs in the pediatric population, looking specifically at the unique advantages and disadvantages of this application of the human–animal bond. We administered a structured interview assessing risks and benefits of assistance dog relationships to 17 families with a child under 18 years who graduated from a single provider (NEADS) over a five-year time period. Benefits were found in 88% of families, and were overwhelmingly social and cognitive, with additional physical and medical benefits for the pediatric client. However, risks, including behavioral, financial, and time/cost issues were significant, becoming a burden in 53% of families. Perhaps more than with adult placements, we found that it was of prime importance to understand the assistance animal in the context of the family, rather than just in relation to the individual with a disability. It is hoped that results of this and future studies will enhance the welfare of both client and assistance animal, as well as the overall success of this unique human–animal relationship.     

Evaluation of on-farm veal calves’ responses to unfamiliar humans and potential influencing factors

The human–animal relationship is an important component of the welfare of farm animals and for this reason animal responsiveness tests to humans are included in on-farm welfare assessment schemes that provide indicators for this. However, apart from the behaviour of stockpersons towards their animals, other factors may also influence animals’ reactivity to humans as observed through behavioural tests, which can add a further layer of complexity to the interpretation of test results. Knowledge of these factors may help a better interpretation of differences from one farm to another in the outcome of human–animal relationship tests, and may provide clues for improving the relationship between animals and humans. The main objective of this study was to identify whether management or environmental factors could influence the outcome of human–animal relationship tests in veal calves. Two tests were performed when calves were aged 14.9 ± 1.6 (SD) weeks in 148 veal farms: the voluntary approach of an unfamiliar human standing at the feeding fence and the reaction towards an unfamiliar human who entered the home pen and tried to touch each calf in a standardised way (Calf Escape Test (CET) – score 0 to 4). Questionnaires were filled in and interviews with the stockpersons were performed in order to obtain information on stockpersons, management, animal and building characteristics. The latency to touch an unfamiliar human at the feeding fence was significantly correlated with the CET scores. Total number of calves on the farm, space allowance, breed, environmental enrichment, stockperson's experience and season of observation influenced the percentage of calves that scored 0 in CET (i.e. calves that could not be approached). Type of milk distribution, type of breed and number of calves per stockperson influenced the percentage of calves that scored 4 in CET (i.e. calves could be touched). For both CET0 and CET4, the level of self-reported contacts by the stockperson (analysed only on the French subset of 36 farms) did not influence the results. This paper concludes that according to the tests conducted on veal calves on commercial farms, factors such as milk distribution method, breed of the calves or the level of experience of stockpersons with veal farming can have an impact on the results of tests focusing on human–animal relationships.     

An approach for identifying the influence of carcass type and environmental features on sarcosaprophagous Diptera communities

Summary. Since the entomosarcosaprophagous community is affected by environmental variables, it needs to be studied under different environmental conditions. In addition, because most studies are usually conducted with biomodels rather than human corpses, it is necessary to verify whether or not the type of decomposing animal matter affects the decomposition process itself, as well as the related fauna. For this reason, a study was conducted on the sarcosaprophagous Diptera community in two different environments of the Region of Murcia (SE Spain), using piglet and chicken carcasses, and Schoenly traps as collecting devices. To analyse possible differences regarding faunal composition among samples, a one-way Permutational Multivariate Analysis of Variance (PERMANOVA) was applied. The results indicate significant differences concerning the bait. In this sense, Calliphoridae, Muscidae, Fanniidae and Sarcophagidae families are the main groups responsible for such differences. In terms of environment-related differences, the only species that contribute are those of the dominant families, Calliphoridae and Muscidae.     

Walking Sole Mates: Dogs Motivating,Enabling and Supporting Guardians' Physical Activity

ABSTRACT

Dog walking is receiving increasing attention in the public health literature as a strategy to improve dog guardians' physical activity levels. Quantitative research suggests that dog guardians walk more often and for longer than non dog-guardians, and offers suggestions as to the reasons for these differences. The purpose of this study was to qualitatively explore dog guardians' walking practices and relationships with their dogs, to better understand how and why dog walking might become an intervention point to enhance physical activity levels. Five focus groups and two interviews were conducted with 16 adult dog guardians. Following an initial analysis of the results, 10 additional dog guardians were individually interviewed to review and confirm the findings. Four themes emerged to explain the dog-walking phenomenon: Transcending the human–animal distinction; Dogs as walking sole mates; Activity/health benefits; and Dogs as social conduits. We argue that an empathetic stance benefits dog guardians because, as valued family members whose health and happiness they are responsible for, their canine companions serve to motivate, enable, and sustain walking behaviors.     

The Attachment of People to Companion Animals

ABSTRACT

This article examines whether the human-companion animal relation, and in particular attachment, can be explained and understood with the help of attachment theory and the “internal working model.” The (perceived) social support and responsivity of the human-animal bond and how these relate to the attachment theory are also discussed.

The research, however, found only weak relationships between owning a companion animal and attachment. Other factors that could influence the attachment of owners toward their animals are discussed.     

The Power of Play

ABSTRACT

This paper explores how peoples' play with companion dogs and cats can challenge the human–animal divide. Data from observation and interviews demonstrate how play honors animals' subjectivity and communication skills, making this everyday activity an act of individualized resistance to human disregard for non-human life. While the notion of human supremacy prevails, this paper examines how interconnection with animals becomes possible – and political – through play.     

Synthesis and biological evaluation of novel antiviral agents as protein–protein interaction inhibitors

Abstract

In continuation of our research efforts toward the identification and optimization for novel inhibitors of interaction between human immunodeficiency virus type 1 integrase and cellular cofactor LEDGF/p75, we designed and synthesized a new series of 4-benzylindole derivatives. Most of the title compounds proved to be able to block this protein–protein interaction (PPI), with a percentage ranging from 30% to 90% at 100?µM. The most promising derivative was compound 10b showing IC₅₀ value of 6.41?µM. The main structure–activity relationships (SAR) are discussed and rationalized by docking studies.     

Donor–Recipient Sex Mismatch in Kidney Transplantation

BackgroundThe lack of reliable human proxies for minor (ie, non-HLA) histocompatibility loci hampers the ability to leverage these factors toward improving transplant outcomes. Despite conflicting reports of the effect of donor–recipient sex mismatch on renal allografts, the association between acute rejection of renal allografts and the development of human alloantibodies to the male H-Y antigen suggested to us that donor–recipient sex mismatch deserved re-evaluation.ObjectiveTo evaluate whether the relationships between donor sex and allograft failure differed by recipient sex.MethodsWe studied recipients of deceased-donor (n = 125,369) and living-donor (n = 63,139) transplants in the United States Renal Data System. Using Cox proportional hazards models stratified by donor type, we estimated the association between donor–recipient sex mismatch and death-censored allograft failure with adjustment for known risk factors, with and without the use of multiple imputation methods to account for potential bias and/or loss of efficiency due to missing data.ResultsThe advantage afforded by male donor kidneys was more pronounced among male than among female recipients (8% vs 2% relative risk reduction; interaction P < 0.01). This difference is of the order of magnitude of several other risk factors affecting donor selection decisions.ConclusionsDonor–recipient sex mismatch affects renal allograft survival in a direction consistent with immune responses to sexually determined minor histocompatibility antigens. Our study provides a paradigm for clinical detection of markers for minor histocompatibility loci.     

The Relationship between Types of Human–Animal Interaction and Attitudes about Animals: An Exploratory Study

Existing theory and research suggests that understanding the nuances of particular instantiations of human–animal relationships is important in promoting positive, mutually beneficial relationships between people and animals. One such aspect of human–animal interaction (HAI) involves species of animal involved in the relationship, and how various types of HAI may impact individuals' attitudes about animals. Therefore, the purpose of this study was to explore if species and/or types of animal ownership were associated with feelings of emotional attachment, commitment, and moral orientation toward animals. A sample of young adults (n = 567) from the 4-H Study of Positive Youth Development completed a survey which included questions about animal ownership and attitudes about animals. Regression analyses demonstrated that the species of animal(s) a person owned significantly predicted all three dimensions of attitudes about animals. In addition, latent class analyses identified three prevalent types of animal interaction (no/few animals, small animals only, large and small animals), and multinomial logistic regression within the mixture model indicated that individuals in these subgroups significantly differed in moral orientation scores. Overall, the analyses strengthen support for the notion that species of animal involved in the interaction matters, and that relationships with various species of animals may differ qualitatively. These findings have implications for understanding the role of the relationship between types of animal ownership and attitudes about animals. Exploring the multifaceted nature of human–animal relationships is important in understanding how to optimize the person and animal characteristics that are associated with adaptive, mutually beneficial human–animal relationships.     

Children with pets do not show higher empathy: A challenge to current views

Abstract

A group of children (n=137) were surveyed with respect to pet ownership and pet preferences to explore the link between the human–animal bond and empathy. The most notable findings—and contrary to our predictions—were: (1) there was no difference in empathy (Bryan Empathy Index) between pet owners and non-owners; (2) there was no correlation between empathy and attachment to pets (Companion Animal Bonding Scale); and (3) higher empathy scores were not related to pet-preference indicators. A more fine-grained examination of the pet-owning group only revealed differences with respect to type of animal owned. Higher empathy was evident with dog ownership as opposed to other pet types. However, this needs to be tempered by the equally interesting observation that lower empathy was related to cat ownership. Regardless of how ownership groups are configured, there is consistent evidence that differentiates cat owners (lower empathy) from dog owners (higher empathy). When pet ownership and pet preference are combined to form new groupings, again, the cat effects and dog effects are evident. Implications extend to the need: (1) for future research on the nature of the human–animal bond; (2) to explore the relationship between personality and animal bonding; and (3) to refine the questions surrounding the animal-based links to empathy, as well as other related constructs such as prosocial behaviour, compassion, self-esteem, self-control, autonomy, affection, stress, responsibility, and perhaps even emotional intelligence, career paths and community service.     

Agreement between different survey instruments to assess incident and prevalent tumors and medical records – results of the Heinz Nixdorf Recall Study

ObjectiveThe validity of participants’ self-reports via questionnaires or interviews in epidemiological studies remains questionable. We examined the agreement of tumors, reported via different survey instruments, with medical records.MethodsWithin the Heinz Nixdorf Recall Study, comprising 4814 subjects aged 45–75 years, tumors were assessed via different survey tools at baseline and 8-year-follow up (FU): personal interviews (CAPI), self-administered questionnaires (SA-Q), physical examinations, short questionnaire/non-responder questionnaire (S-/N-Q) and telephone interviews. Information on each self-reported tumor was coded via ICD-10, WHO-Version 2010, and evaluated against medical records.ResultsDuring FU, 95% of 1083 self-reported incident tumors in 623 individuals, at baseline, 65% of 473 prevalent tumors in 406 individuals could be evaluated. Agreement of the main assessment tools, CAPI and SA-Q, with medical records was 90.1% and 88.4% (FU) and 91.0% (baseline-CAPI).Best agreement was in tumors of prostate (baseline-CAPI: 97.8%; 5-year-FU-CAPI: 96.9%, SA-Q: 95.7%) and breast (baseline-CAPI: 93.2%; 5-year-FU-CAPI: 100.0%, SA-Q: 98.8%).DiscussionAgreement of CAPI and SA-Q with medical records was good. To assess incident tumors, SA-Q emerged as favorable, as it is least expensive and easy to be applied. Especially for tumors of prostate and breast, cost-intensive and time-consuming validation with medical records may not be necessary.     

Human–Animal Bonds Between Zoo Professionals and the Animals in Their Care

Some human‐animal relationships can be so positive that they confer emotional well‐being to both partners and can thus be viewed as bonds. In this study, 130 delegates at zoo research and training events completed questionnaires in which they were asked about their professional work in the zoo and whether they believed they had established bonds with any animals. They were also asked to indicate agreement or disagreement with several statements about human‐animal bonds. Results showed that many zoo professionals consider that they have established bonds with some of their animals; 103 respondents believed that they had a bond with at least one animal, and 78 of these identified that the bond was with a zoo animal. The most frequent bonds reported were with primates (n = 24) and carnivores (n = 28). Perceived benefits of these bonds to the respondents included both operational (animal easier to handle, easier to administer treatments to) and affective (sense of well‐being, enjoyment at being with the animal). Identifying benefits to the animals was more difficult. Most respondents identified similar benefits for their animals as for themselves, i.e. operational (animal responded more calmly, appeared less stressed) and affective (animal appeared to enjoy contact with respondent, seemed more content). This suggests that bonding between zoo professionals and their animals could have profound consequences for the management and welfare of the animals, not to mention the job satisfaction of the people involved.

Attitudes of Dairy Farmers toward Cow Welfare in Relation to Housing,Management and Productivity

ABSTRACT

The quality of stockmanship contributes to the human–animal relationship, animal welfare and productivity. Attitudes can affect the way farmers treat their animals, the environment they provide the animals with, and even their own job satisfaction through the feedback received from the animals. Farmers' perceptions of animals have also been shown to have an impact on productivity. We investigated 161 Finnish dairy farmers' attitudes toward improving animal welfare through an attitude questionnaire that used the Theory of Planned Behavior as a theoretical framework. The theory states that personal attitude, subjective norms, and perceived behavioral control, together shape an individual's behavioral intentions and behaviors. To study the relationship between attitudes, animal welfare, and milk production, we used environment-based animal welfare indicator data consisting of categorized housing and management parameters, and mean milk production data. Non-parametric partial correlation analyses and regression analyses revealed that perceiving the measures to improve animal welfare to be important and easy were positively, although weakly, related to higher animal welfare standards/indicators, while no connection with production was established. Contrary to our expectations, sources of subjective norms, such as an agricultural adviser, were mostly negatively linked with animal welfare indicators and even with production. The farmers considered taking care of their own well-being as the most important way of improving animal welfare, and intending to do so was weakly but positively linked with animal welfare indicators. Any causal relationships, however, cannot be derived from the data.     

Advances in Applied Zoo Animal Welfare Science

ABSTRACT

Nonhuman animal welfare science is the scientific study of the welfare state of animals that attempts to make inferences about how animals feel from their behavior, endocrine function, and/or signs of physical health. These welfare measurements are applicable within zoos yet inherently more complex than in farms and laboratories. This complexity is due to the vast number of species housed, lack of fundamental biological information, and relatively lower sample sizes and levels of experimental control. This article summarizes the invited presentations on the topic of “Advances in Applied Animal Welfare Science,” given at the Fourth Global Animal Welfare Congress held jointly by the Detroit Zoological Society and the World Association of Zoos and Aquariums in 2017. The article focuses on current trends in research on zoo animal welfare under the following themes: (a) human–animal interactions and relationships, (b) anticipatory behavior, (c) cognitive enrichment, (d) behavioral biology, and (e) reproductive and population management. It highlights areas in which further advancements in zoo animal welfare science are needed and the challenges that may be faced in doing so.     

Prevalence and risk factors for overweight horses at premises in Sweden assessed using official animal welfare control data

Background

There are Swedish animal welfare regulations concerning the body condition of horses and general advice on keeping horses including that horses should be fed so that they do not become over- or underweight relative to their use. Compliance is assessed by official animal welfare inspectors. The objective of this study was to determine whether the national animal welfare control database could be used to estimate the prevalence and risk factors for overweight horses in Sweden. The official animal welfare control checklist for horses contains 45 checkpoints (CP) of which CP-8 pertains to the acceptability of the horses’ body condition including whether they were under- or overweight. Prevalence of non-compliance with CP-8, with 95 % confidence intervals (CI), were calculated for the years 2010–2013. Associations between risk factors and non-compliance for overweight body condition were estimated using logistic regression and expressed as odds ratios (OR) with 95 % CIs.

Results

Of 7870 premises with registered horses that were inspected against CP-8, a total of 63 premises had non-compliant inspections due to overweight horses (0.80 %; CI 0.62, 1.02 %). In multivariable analyses, premises that were non-compliant with requirements for the care of sick or injured horses (OR 3.52; CI 1.51, 8.22) or with the requirements for feeding a balanced high-quality diet (OR 5.15; CI 2.49, 10.67) had greater odds of having overweight horses. Premises that also kept other species for meat production were more likely to have overweight horses (OR 2.12; CI 1.18, 3.81) whereas professional horse establishments were less likely (OR 0.09; 0.01, 0.64). Overweight horses were more likely in summer compared to winter (OR 2.18; CI 1.02, 4.70). Premises in regions of Sweden with more horses in relation to the human population were less likely to have overweight horses (OR 0.97; CI 0.95, 1.00).

Conclusions

Official animal welfare control data may be used to monitor the premises prevalence of overweight horses in Sweden. Strategies to reduce the prevalence of overweight horses should focus on education about equine care and nutrition, especially summer grazing.
