Visitor Behaviors and Perceptions of Jaguar Activities

ABSTRACT

Zoo animals serve an important function in helping educate the public about their conservation needs. Despite this important function, little is understood about how visitors perceive different zoo exhibits and the animals that reside within them. In the present study, the behaviors displayed by two jaguars located at the Woodland Park Zoo were correlated with visitor behaviors and perceptions. Overall, visitors perceived their enjoyment to be lower when a jaguar was out of sight and rated the behavioral welfare of the jaguar to be lower when it was engaged in stereotypic behaviors. In addition, visitors who described a jaguar's behavior as stereotypic were significantly more likely to give lower ratings than those who perceived the jaguar to be active. It is suggested that by understanding how visitors perceive exhibited animals, zoos can address these perceptions in order to create more positive experiences for their visitors.     

Technoscientific bespoking: Animals,publics and the new genetics

This paper examines the public understanding of science, especially biotechnology and the new genetics, in light of the symbolic roles of animals in the constitution of cultural identities. As such, the paper expands on the critical approach to public understanding of science, with its emphasis upon the way local identities impact upon the apprehension of, and trust in, science and scientific institutions. In particular, the new genetics raises issues about what sorts of broader public identities are mobilized. It is argued that, on the one hand, the complex symbolic role of animals is linked to a wide and contradictory range of modern Western identities, and thus potentially to volatility in the public's response to such biotechnological innovation. On the other, technoscientific bespoking, by rendering animals 'ready-to-order', might catastrophically curtail the symbolic role of animals in human identities, and thus provoke a general anxiety toward new genetics. Some political and research implications of the analysis are briefly explored.     

The Soul-Sucking Wasp by Popular Acclaim – Museum Visitor Participation in Biodiversity Discovery and Taxonomy

Taxonomy, the science of describing and naming of the living world, is recognized as an important and relevant field in modern biological science. While there is wide agreement on the importance of a complete inventory of all organisms on Earth, the public is partly unaware of the amount of known and unknown biodiversity. Out of the enormous number of undescribed (but already recognized) species in natural history museum collections, we selected an attractive example of a wasp, which was presented to museum visitors at a special museum event. We asked 300 visitors to vote on a name for the new species and out of four preselected options, Ampulex dementor Ohl n. sp. was selected. The name, derived from the ‘soul sucking’ dementors from the popular Harry Potter books is an allusion to the wasps'' behavior to selectively paralyze its cockroach prey. In this example, public voting on a scientific name has been shown to be an appropriate way to link museum visitors emotionally to biodiversity and its discovery.     

Genomics research in the UK—the social science agenda

Abstract

We sketch the development of UK genetics and genomics research, and emphasize the UK's key role in the international genetics and genomics research community. We highlight in particular the part played by the UK's Research Councils and other funders. With the move from genomics to post-genomics research, the field is diversifying, and interdisciplinarity becomes increasingly important, as traditional disciplinary boundaries become blurred, or break down, in the face of newly emerging sciences. We consider the changing nature of health and ill health in the developed and developing world, and questions about the complex nature of the relationships between genes and the environment, and their future implications for human health and human populations. We describe the ESRC's activities, stressing the importance of both the social, ethical and legal issues raised by these emerging disciplines, and of public engagement. Finally, we link the data handling and analysis issues raised by these emerging sciences, with other new research areas, in particular the UK's e-Science programme.     

Beyond the genome: Reconstituting the new genetics

The mapping and sequencing of the human genome has been the 'Holy Grail' of the new genetics, and its publication marks a turning point in the development of modern biotechnology. However, the question remains: what has been the impact of this discovery on how biotechnology develops in science, and in society at large? Using concepts developed in the social studies of science and technology, the paper begins by rehearsing the historical development of the Human Genome Project (HGP), and suggests that its translation into genomics has been achieved through a process of 'black-boxing' to ensure stabilization. It continues by exploring the extent to which the move to genomics is part of a paradigm shift in biotechnology resulting from the conceptual and organizational changes that have occurred following the completion of HGP. The discussion then focuses on whether genomics can be seen as part of the development of socially robust knowledge in late modernity. The paper suggests that there is strong evidence that a transformation is indeed taking place. It concludes by sketching a social scientific agenda for investigating the reconstitution of the new genetics in a post-genomic era using a 'situated' analytic approach based on an understanding of techno-scientific change as both emergent and contingent.     

Assessing the Effects of New Primate Exhibits on Zoo Visitors' Attitudes and Perceptions by Using Three Different Assessment Methods

ABSTRACT

Using three different methods, this study investigated how zoo visitors behaved in response to both old and new exhibits of four nonhuman primate species and how they perceived these primates. On-site observations showed that zoo visitors were more likely to stop in front of new exhibits and spend more time viewing new exhibits compared with old exhibits. Response to an on-site questionnaire also showed that zoo visitors perceived primates in the new exhibits more positively than the same animals in the old exhibits. The results from these two types of local assessment indicate that the attractiveness and holding power of the new exhibits was greater than that of the old. However, the results of a questionnaire given to zoo visitors on leaving the zoo showed that the preference ranks of the visitors for the four primate species did not increase after the new exhibits were established, indicating that the new exhibits did not change the zoo visitors' perception of primates relative to other zoo animals. Using all three assessment methods appears to be of considerable value for the assessment of visitors' perceptions towards new exhibits in terms of both the immediate locality and the zoo as a whole.     

Second dose of measles, mumps, and rubella vaccine: questionnaire survey of health professionals

ObjectiveTo determine the knowledge, attitudes, and practices among health professionals regarding the measles, mumps, and rubella (MMR) vaccine, particularly the second dose.Design Self administered postal questionnaire survey.Setting North Wales Health Authority, 1998.Participants 148 health visitors, 239 practice nurses, and 206 general practitioners.Results Concerning the second dose of the vaccine, 48% of the professionals (220/460) had reservations and 3% (15) disagreed with the policy of giving it. Over half the professionals nominated health visitors as the best initial source of advice on the second vaccine. 61% of health visitors (86/140), compared with 46% of general practitioners (73/158), reported feeling very confident about explaining the rationale of a two dose schedule to a well informed parent, but only 20% (28/138) would unequivocally recommend the second dose to a wavering parent. 33% of the practice nurses (54/163) stated that the MMR vaccine was very likely or possibly associated with Crohn''s disease and 27% (44/164) that it was associated with autism. Nearly a fifth of general practitioners (27/158) reported that they had not read the MMR section in the “green book,” and 29% (44/152) reported that they had not received the Health Education Authority''s factsheet on MMR immunisation.Conclusions Knowledge and practice among health professionals regarding the second dose of the MMR vaccine vary widely. Many professionals are not aware of or do not use the good written resources that exist, though local educational initiatives could remedy this.

Visitor Influence on the Behavior of Captive Greater Rheas (Rhea americana,Rheidae Aves)

Visitors can affect and reduce the welfare of nonhuman animals. The Belo Horizonte Zoo, Brazil, had a group of greater rheas intended for reintroduction to the wild. Because this group received public visitation, evaluating its effect on the birds' behavior and welfare was important. The study conducted 60 hr of behavioral observations: 30 with, and 30 without, visitors in front of the birds' enclosure. The study, conducted April–December 2009, collected data using scan sampling with instantaneous recording of behavior every minute. The study collected data on public behavior, visitor density, and time spent observing the birds. More than 4,000 persons visited the birds' enclosure: 9.86 s average time spent. Public behaviors most expressed were walking-watching-talking and stopped-watching-talking; visitors or not, greater rheas' most expressed behaviors (inversed between treatments) were foraging and walking alert; defecating/urinating and other behaviors differed statistically between treatments. Walking alert was most expressed in the presence of visitors; defecating/urinating and other behaviors were most expressed in their absence. Greater rheas seemed to habituate to visitors. Birds' behaviors differed little in visitors' presence or absence.     

In-silico network-based analysis of drugs used against COVID-19: Human well-being study

IntroductionResearchers worldwide with great endeavor searching and repurpose drugs might be potentially useful in fighting newly emerged coronavirus. These drugs show inhibition but also show side effects and complications too. On December 27, 2020, 80,926,235 cases have been reported worldwide. Specifically, in Pakistan, 471,335 has been reported with inconsiderable deaths.Problem statementIdentification of COVID-19 drugs pathway through drug-gene and gene−gene interaction to find out the most important genes involved in the pathway to deal with the actual cause of side effects beyond the beneficent effects of the drugs.MethodologyThe medicines used to treat COVID-19 are retrieved from the Drug Bank. The drug-gene interaction was performed using the Drug Gene Interaction Database to check the relation between the genes and the drugs. The networks of genes are developed by Gene MANIA, while Cytoscape is used to check the active functional association of the targeted gene. The developed systems cross-validated using the EnrichNet tool and identify drug genes'' concerned pathways using Reactome and STRING.ResultsFive drugs Azithromycin, Bevacizumab, CQ, HCQ, and Lopinavir, are retrieved. The drug-gene interaction shows several genes that are targeted by the drug. Gene MANIA interaction network shows the functional association of the genes like co-expression, physical interaction, predicted, genetic interaction, co-localization, and shared protein domains.ConclusionOur study suggests the pathways for each drug in which targeted genes and medicines play a crucial role, which will help experts in-vitro overcome and deal with the side effects of these drugs, as we find out the in-silico gene analysis for the COVID-19 drugs.     

Ordinary ethics: lay people's deliberations on social sex selection

Abstract

This article summarises the results of a research project that used a scenario about sex selection of embryos for social reasons as a basis for discussion groups with lay people. The aim of the research was to examine the processes by which non-professionals make ethical evaluations in relation to a contested area in medical genetics. We note in particular the role played in the discussions by expressions of instinct; making distinctions; rational argument; reference to principles; use of personal experience; analogies and examples; slippery slope arguments and meta-reflections. The implications for developing processes of public consultation and debate are also considered.     

Regulation of Sugar and Ethanol Metabolism in Saccharomyces cerevisiae

Abstract

This review briefly surveys the literature on the nature, regulation, genetics, and molecular biology of the major energy-yielding pathways in yeasts, with emphasis on Sacchuromyces cerevisiae. While sugar metabolism has received the lion's share of attention from workers in this field because of its bearing on the production of ethanol and other metabolites, more attention is now being paid to ethanol metabolism and the regulation of aerobic metabolism by fermentable and non-fermentable substrates. The utility of yeast as a highly manipulable organism and the discovery that yeast metabolic pathways are subject to the same types of control as those of higher cells open up many opportunities in such diverse areas as molecular evolution and cancer research.     

Evaluation of Public Engagement Activities to Promote Science in a Zoo Environment

Scientists are increasing their efforts to promote public engagement with their science, but the efficacy of the methods used is often not scientifically evaluated. Here, we designed, installed and evaluated the educational impact of interactive games on touchscreens at two primate research centres based in zoo environments. The games were designed to promote interest in and understanding of primates and comparative psychology, as a scaffold towards interest in science more generally and with the intention of targeting younger individuals (under 16''s). We used systematic observational techniques and questionnaires to assess the impact of the games on zoo visitors. The games facilitated increased interest in psychology and science in zoo visitors, and changed the knowledge of visitors, through demonstration of learning about specific scientific findings nested within the games. The impact of such devices was greatest on younger individuals (under 16''s) as they were significantly more likely to engage with the games. On the whole, therefore, this study demonstrates that interactive devices can be successful educational tools, and adds to the growing body of evidence that conducting research on public view in zoos can have a tangible impact on public engagement with science.

In search of the Holy Grail: Media discourse and the new human genetics

It has widely been recognized that the media play a key role in framing debates about genetic issues. This paper provides an overview of the major areas of debate within the social scientific literature on media, public understanding of science and human genetics. It evaluates current approaches to assessing the role of the media in influencing public policy debates. It argues that an analysis of the strategies of news sources should occupy a central role in furthering understanding about the ways in which various social actors seek to influence public policy agendas. At present, within the field of human genetics, only a handful of researchers have systematically examined the strategies of news sources from the perspective of the sources themselves. While recent research has focused upon identifying the major sources and how they are used in science reporting, there remains much to be done in uncovering the processes of negotiation and contestation among social actors prior to issues gaining media coverage.     

In search of genohype: A content analysis of biotechnology company documents

A symbology of power is assigned to DNA and genetics both in the media and in scientific publications. The term 'genohype' was offered by Holtzman (Are genetic tests adequately regulated? Science , 286 (4539), pp. 409-410, 1999) to characterize the discourse of exaggerated claims and hyperbole attached to DNA and the effort to map the human genome. In this paper, I examine the relationship between language and ideology in a systematic search for 'genohype' in biotechnology industry investor handbooks and annual reports. Three forms for 'genohype' are identified and one of these - 'possessing nature' - is isolated as involving the making of medicine. Using the NVivo software, a search of finance-related and health-related keywords showed that 'genohype' is basically not present in this investor material. The results are interpreted as reflecting the separate domains of financial capital and intellectual capital that are the ideological theatres for the production of medical commodities.     

Animal Activity and Visitor Learning at the Zoo

ABSTRACT

This study investigated the effect animal activity had on information visitors attended to at three bear exhibits. Attention was used as an indirect measure of what information visitors are consciously processing, or learning. It was hypothesized that visitors would be more likely to attend to specific information about animal behavior when bears were active rather than when inactive or out of sight. Visitor conversations were recorded during observations of polar, sloth and spectacled bears. Conversation was coded according to its content (animal-directed, human-focused, behavior, other) and to the corresponding behavior of the bear (active, inactive, pacing, not visible). The energy level of the activity was also considered. The hypothesis was supported for the polar bears, but less so for the other two bears. Behavior conversation was highest and human-directed conversation was lowest in the presence of highly animated polar bears. Behavior content was limited in the presence of the less animated sloth and spectacled bears. However, it was still significantly less frequent, and human content more frequent, when the sloth and spectacled bears were pacing and/or not visible. Therefore, what visitors attended to was influenced by what the bears were doing. The findings suggest that animated activity (rather than the more broadly defined ‘activity’) elicits the most visitor attention to behavior, and this in turn potentially facilitates visitor learning.
