Clostridium Difficile Associated Disease (Cdad), Rivka H. Borger
Clostridium Difficile Associated Disease (Cdad), Rivka H. Borger
The Science Journal of the Lander College of Arts and Sciences
Clostridium difficile bacteria (C. difficile) are a spore-forming species of bacteria that lies dormant in the colon, in the presence of normal intestinal flora. Due to overuse of certain antibiotics, normal intestinal bacteria may be depleted, and combined with other possible risk factors, allow C. difficile bacterial spores to develop into active, infectious, and extremely resistant toxin-producing bacteria. The toxins cause severe damage and inflammation to the intestinal wall that can result in gastrointestinal discomfort and severe pseudomembranous enterocolitis that must be treated with a low-risk C. difficile targeting defense.
Meso-Zeaxanthin Ocular Supplementation Trial In Normals (Most-N), James Loughman
Meso-Zeaxanthin Ocular Supplementation Trial In Normals (Most-N), James Loughman
Conference Papers
Purpose: At the macula, the carotenoids meso-zeaxanthin (MZ), lutein (L) and zeaxanthin (Z) are collectively referred to as macular pigment (MP). To date only one study has reported on MP augmentation following supplementation with MZ, L and Z. However, that study measured only one retinal location (0.75°) and may not have been able to detect changes, if any, at other degrees of retinal eccentricity. Our study was designed to investigate (in a double-blind, randomized placebo controlled fashion) changes in MP optical density (MPOD, including its entire spatial profile), and serum concentrations of the macular carotenoids in response to supplemental MZ, …

Bush, Obama And Beyond: Observations On The Prospect For Fact Checking Executive Department Threat Claims Before The Use Of Force, Leslie Gielow Jacobs
Bush, Obama And Beyond: Observations On The Prospect For Fact Checking Executive Department Threat Claims Before The Use Of Force, Leslie Gielow Jacobs
McGeorge School of Law Scholarly Articles
This piece looks at the recurring problem of inflated threat claims offered by executive branch actors to persuade the Nation to consent to the use of force. It sets out the experience of the Bush Administration’s use of incorrect threat claims to persuade the country to consent to the use of force in Iraq as a backdrop to evaluating the President Obama’s use of threat claims to support the continuing use of force in Afghanistan. Although comparison of threat advocacy by the Bush and Obama administrations must be imperfect, it allows for some observations about the extent to which the …

Bat Habitat Use And Roost Tree Selection For Northern Long-Eared Myotis (Myotis Septentrionalis) In North-Central Ohio, Timothy J. Krynak
Bat Habitat Use And Roost Tree Selection For Northern Long-Eared Myotis (Myotis Septentrionalis) In North-Central Ohio, Timothy J. Krynak
Masters Theses
Understanding roosting behavior and habitat use of bats is an important component when unraveling life histories and their ecology. Ohio remains under-represented in published information of bats compared to surrounding states. This large scale survey in 2002–2003 and Myotis septentrionalis radio telemetry study in 2005 is one of the few conducted within the state and is the first in Ohio’s North-Central region. It is also the first study conducted where net sites were chosen randomly and spatially distributed to adequately survey bat populations within Cuyahoga Valley National Park and Cleveland Metroparks. This survey documented seven species (n = 668), with …

One Eternal Round, Hugh Nibley, Michael D. Rhodes
Maxwell Institute Publications
Preface
On 23 February 2005, I, along with a group of colleagues including John W. Welch, John Gee, and others, gathered in the front room of Hugh Nibley’s home. Hugh was there in a hospital bed, but was unconscious. His wife, Phyllis, and some of their children were also present. We were meeting to decide what to do with Hugh’s unfinished book, One Eternal Round. He had been working on it for more than f ifteen years before he became too ill to continue. A few months before, we had gathered together all the materials on the book from Hugh’s …
Understanding Mortality Rates Of Laying Hens In Cage-Free Egg Production Systems, The Humane Society Of The United States
Understanding Mortality Rates Of Laying Hens In Cage-Free Egg Production Systems, The Humane Society Of The United States
Agribusiness Collection
In cage-free egg production systems, concerns have been raised over hen mortality rates. High mortality is an obvious indicator of poor welfare, and problems should be addressed without delay. It is important to note, however, that mortality can vary substantially between hen flocks, and that some cage-free systems have healthy flocks that do not suffer substantial death losses. These systems can serve as models for the rest of the industry, since mortality is not inherent to any particular system, but a consequence of how well the system is managed.

About Fish, Humane Society Institute For Science And Policy
Aquaculture Collection
Although a number of fish species have been studied in their freshwater life stages, further research on the behavior and habitat requirements of ocean-going fish is required. While fishes have historically been regarded as more “primitive” than other vertebrate groups, Rodriguez et al concluded that several memory and learning systems of bony fishes are noticeably similar to those of reptiles, birds, and mammals. When animals as small and under appreciated as fish display complex mating systems, parental care, and demonstrate the ability to traverse significant distances using olfactory and celestial cues, it is clear that previously established definitions of intelligence …

About Turkeys, The Humane Society Of The United States
Agribusiness Collection
John James Audubon, a well-known bird expert and nature enthusiast, described wild turkeys as birds of great beauty. The history and origin of wild turkeys is uncertain, yet many share Audubon’s sentiment that the wild turkey is “one of the most interesting of the birds indigenous to the United States of America.” Today, wild turkeys can be found throughout the nation. Following the selection of the bald eagle as the American symbol, Benjamin Franklin remarked that the turkey was more “respectable”, and a “true original native”.

About Chickens, The Humane Society Of The United States
Agribusiness Collection
The chicken is the world’s most numerous domesticated bird, with over 52 billion farmed worldwide in 2008, rivaling the dog as the most ubiquitous domestic animal globally. These birds have fascinated scholars and researchers since the dawn of Western civilization, and recent studies are beginning to reveal the depths of their complexity and cognitive ability. According to Andrew F. Fraser, professor of veterinary surgery at Memorial University of Newfoundland, and Donald M. Broom, professor of animal welfare at University of Cambridge: “Those who have studied the behaviour of the domestic fowl in detail…, especially those who have looked at feral …
An Hsi Report: Food Safety And Cage Egg Production, Humane Society International
An Hsi Report: Food Safety And Cage Egg Production, Humane Society International
HSI REPORTS
Governments have begun legislating against cage egg production and a growing number of major food retailers, restaurant chains, and foodservice providers worldwide are switching to cage-free eggs. Extensive scientific evidence strongly suggests this trend will improve food safety. All fifteen scientific studies published in the last five years comparing Salmonella contamination between caged and cage-free operations found that those confining hens in cages had higher rates of Salmonella, a leading cause of food poisoning worldwide. This has led prominent consumer advocacy organizations, such as the Center for Food Safety, to oppose the use of cages to confine egg-laying hens.
Laboratory Rodent Welfare: Thinking Outside The Cage, Jonathan P. Balcombe
Laboratory Rodent Welfare: Thinking Outside The Cage, Jonathan P. Balcombe
Laboratory Experiments Collection
This commentary presents the case against housing rats and mice in laboratory cages; the commentary bases its case on their sentience, natural history, and the varied detriments of laboratory conditions. The commentary gives 5 arguments to support this position: (a) rats and mice have a high degree of sentience and can suffer, (b) laboratory environments cause suffering, (c) rats and mice in the wild have discrete behavioral needs, (d) rats and mice bred for many generations in the laboratory retain these needs, and (e) these needs are not met in laboratory cages.

I’m grateful to the editors for soliciting critiques of my commentary and for the opportunity to respond. Because one of the respondents (Patterson-Kane, 2010/this issue) does not take issue with the main points of my article, whereas the other (Blanchard, 2010/this issue) does, I focus my remarks here mostly on Blanchard’s critique.

Do Zoos And Aquariums Promote Attitude Change In Visitors? A Critical Evaluation Of The American Zoo And Aquarium Study, Lori Marino, Scott O. Lilienfeld, Randy Malamud, Nathan Nobis, Ron Broglio
Zoos and Aquariums Collection
Modern-day zoos and aquariums market themselves as places of education and conservation. A recent study conducted by the American Zoo and Aquarium Association (AZA) (Falk et al., 2007) is being widely heralded as the first direct evidence that visits to zoos and aquariums produce long-term positive effects on people’s attitudes toward other animals. In this paper, we address whether this conclusion is warranted by analyzing the study’s methodological soundness. We conclude that Falk et al. (2007) contains at least six major threats to methodological validity that undermine the authors’ conclusions. There remains no compelling evidence for the claim that zoos …
Integrated Pest Management (Ipm) For Vertebrates: Do We Need To Broaden This Concept?, John Hadidian
Integrated Pest Management (Ipm) For Vertebrates: Do We Need To Broaden This Concept?, John Hadidian
Ecology Collection
The concepts and practices of Integrated Pest Management (IPM) are historically grounded in programs aimed at insects and disease-causing organisms affecting agriculture. When applied to vertebrates, IPM concepts have most often been used in rodent control programs. Still, IPM is a powerful model that arguably can, and should, apply to conflicts with any “pest” or problem-causing organism. It may be time to examine contemporary IPM approaches and their relation to traditional vertebrate pest control more closely. Vertebrate IPM should encompass not only the development of sound and practical steps to shape decision-making and actions, but a dialogue about ethics as …

Attitudes Towards Animals Collection
The growth of human-animal studies (HAS) over the past twenty years can be seen in the explosion of new books, journals, conferences, organizations, college programs, listserves, and courses, both in the United States and throughout Europe, Australia, New Zealand, and Canada. We look as well at trends in the field, including the increasing popularity of animal-assisted therapy programs, the rise of new fields like trans-species psychology and critical animal studies, and the importance of animal welfare science. We also discuss the problems continuing to face the field, including the conservative culture of universities, the interdisciplinary nature of the field, the …

The article discusses the importance of biodiversity and on how people protect animals and habitats. It describes the conservation psychology and conservation social work. It suggests that there will be fewer people who will actually be able to make a positive difference in the relationships with animals and ecosystems.
Octopuses (Enteroctopus Dofleini) Recognize Individual Humans, Roland C. Anderson, Jennifer A. Mather, Mathieu Q. Monette, Stephanie R.M. Zimsen
Octopuses (Enteroctopus Dofleini) Recognize Individual Humans, Roland C. Anderson, Jennifer A. Mather, Mathieu Q. Monette, Stephanie R.M. Zimsen
Sentience Collection
This study exposed 8 Enteroctopus dofleini separately to 2 unfamiliar individual humans over a 2-week period under differing circumstances. One person consistently fed the octopuses and the other touched them with a bristly stick. Each human recorded octopus body patterns, behaviors, and respiration rates directly after each treatment. At the end of 2 weeks, a body pattern (a dark Eyebar) and 2 behaviors (reaching arms toward or away from the tester and funnel direction) were significantly different in response to the 2 humans. The respiration rate of the 4 larger octopuses changed significantly in response to the 2 treatments; …
Squid Dances: An Ethogram Of Postures And Actions Of Sepioteuthis Sepioidea Squid With A Muscular Hydrostatic System, Jennifer A. Mather, Ulrike Griebel, Ruth A. Byrne
Squid Dances: An Ethogram Of Postures And Actions Of Sepioteuthis Sepioidea Squid With A Muscular Hydrostatic System, Jennifer A. Mather, Ulrike Griebel, Ruth A. Byrne
Sentience Collection
A taxonomy of the movement possibilities for any species, within the constraints of its neural and skeletal systems, should be one of the foundations of the study of its behaviour. Caribbean reef squid, Sepioteuthis sepioidea, appear to have many degrees of freedom in their movement as they live in a three-dimensional habitat and have no fixed skeleton but rather a muscular hydrostatic one. Within this apparent lack of constraints, there are regularities and patterns of common occurrences that allow this article to describe an ethogram of the movements, postures and positions of squid. Squid have a combination of bent, …
Vigilance And Antipredator Responses Of Caribbean Reef Squid, Jennifer A. Mather
Vigilance And Antipredator Responses Of Caribbean Reef Squid, Jennifer A. Mather
Sentience Collection
Antipredator responses, especially those of open-ocean squid, have been seldom studied in the natural environment. Sepioteuthis sepioidea, observed by snorkellers near the shore in early morning/late afternoon, produced an average of eight moves of over 1m per hour, apparently mostly antipredator behaviours. Close approaches by herbivorous parrotfish elicited no response in 74% of encounters; otherwise, squid produced agonistic zebra stripes or startle-mantle-dots skin patterns. Predatory bar jack fish caused flight but not zebra displays, and squid usually paled and fled quickly (66%) from snapper. The speed of approach was the best predictor for flight and display responses to snapper, …
Male Territoriality In A Social Sciurid, Cynomys Gunnisoni: What Do Patterns Of Paternity Tell Us?, J. L. Verdolin, C. N. Slobodchikoff
Male Territoriality In A Social Sciurid, Cynomys Gunnisoni: What Do Patterns Of Paternity Tell Us?, J. L. Verdolin, C. N. Slobodchikoff
Veterinary Science and Medicine Collection
In many social sciurids, male territoriality confers significant mating advantages. We evaluated resident male paternity in Gunnison’s prairie dogs (Cynomys gunnisoni), a colonial ground-dwelling sciurid, where males and females cooperatively defend territories. Contrary to findings reported for other social sciurids, our results show that territorial resident males do not gain significant reproductive advantages. Resident males sired the majority of offspring from their respective territories only 10.5% of the time. A single non-resident male sired equal or greater number of offspring than any single resident male 71.2% of the time. While adult males were more likely to sire a greater number …

Behavior Of A Solitary Sociable Female Bottlenose Dolphin (Tursiops Truncatus) Off The Coast Of Kent, Southeast England, Sonja Eisfeld, Mark P. Simmonds, Laura R. Stansfield
Ethology Collection
This article provides a report of the behavior of a solitary sociable dolphin studied on the southeast coast of England in 2007. This is the first study of its kind in which behavior of such a nonhuman animal was systematically studied. By the time of this study, this young female was highly interactive with people in the water. People accompanied the dolphin for 18.4% of the 100 hr of observation, and their presence changed her behavior. The study recorded 39 different behaviors; feeding and resting behaviors declined in frequency in the presence of people. In addition, the dolphin exhibited behavior …
Quality Prevails Over Identity In The Sexually Selected Vocalisations Of An Ageing Mammal, Elodie F. Briefer, Elisabetta Vannoni, Alan G. Mcelligott
Quality Prevails Over Identity In The Sexually Selected Vocalisations Of An Ageing Mammal, Elodie F. Briefer, Elisabetta Vannoni, Alan G. Mcelligott
Ethology Collection
Background: Male sexually selected vocalisations generally contain both individuality and quality cues that are crucial in intra- as well as inter-sexual communication. As individuality is a fixed feature whereas male phenotypic quality changes with age, individuality and quality cues may be subjected to different selection pressures over time. Individuality (for example, morphology of the vocal apparatus) and quality (for example, body size and dominance status) can both affect the vocal production mechanism, inducing the same components of vocalisations to convey both kinds of information. In this case, do quality-related changes to the acoustic structure of calls induce a modification of …

Discourse And Wolves: Science, Society, And Ethics, William S. Lynn
Human and Animal Bonding Collection
Wolves have a special resonance in many human cultures. To appreciate fully the wide variety of views on wolves, we must attend to the scientific, social, and ethical discourses that frame our understanding of wolves themselves, as well as their relationships with people and the natural world. These discourses are a configuration of ideas, language, actions, and institutions that enable or constrain our individual and collective agency with respect to wolves.
Scientific discourse is frequently privileged when it comes to wolves, on the assumption that the primary knowledge requirements are matters of ecology, cognitive ethology, and allied disciplines. Social discourse …
