Nutrient loss and accumulation as well as associated environmental degradation have been a concern for animal agriculture for many decades. Federal and New York (NY) regulations apply to Concentrated Animal Feeding Operations and a comprehensive nutrient management plan (CNMP) is required for regulated farms. The whole farm nutrient mass balance…

The shadows cast by moving objects enable human adults and infants to infer the motion trajectories of objects. Nonhuman animals must also be able to discriminate between objects and their shadows and infer the spatial layout of objects from cast shadows. However, the evolutionary and comparative developmental origins of sensitivity to cast…

Behavior modification with children has been popularized through television shows such as "Super Nanny" and "Nanny 911". The popularity of these shows may be related to the demand parents have for improving their children's behavior. Interestingly, an approach adopted by "The Dog Whisperer" may prove effective when used with children. The purpose…

This study investigated the effect of isoflavone aglycone (IA) on the learning and memory performance of senescence-accelerated mice, and explored its neural protective mechanism. Results showed that SAM-P/8 senescence-accelerated mice treated with IA performed significantly better in the Y-maze cognitive test than the no treatment control (P less…

Purpose: Digital kymography and vocal fold curve fitting are blended with detailed symmetry analysis of kymograms to provide a comprehensive characterization of the vibratory properties of injured vocal folds. Method: Vocal fold vibration of 12 excised canine larynges was recorded under uninjured, unilaterally injured, and bilaterally injured…

The current study examined the variables that influence postreinforcement pause (PRP) duration in rats when wheel running serves as the reinforcing consequence. The relationship between revolutions and PRP duration when revolutions were manipulated within a session and the effect of changing the response requirement from fixed to variable on PRP…

Eight pigeons responded in a concurrent-chains procedure in which terminal-link schedules changed pseudorandomly across sessions. Pairs of terminal-link delays either summed to 15 s or to 45 s. Across sessions, the location of the shorter terminal link changed according to a pseudorandom binary sequence. On some terminal links, food was withheld…

In this essay, I explore a child's experience of engaging with animals, and through animals, humans in her life. For children and adults alike, most of life happens in mundane moments. Yet, bumped along through time and mundane everydayness, we are periodically struck by something. This is a story about a child's experience of…

Because many different sensory modalities contribute to spatial learning in rodents, it has been difficult to determine whether spatial navigation can be guided solely by visual cues. Rodents moving within physical environments with visual cues engage a variety of nonvisual sensory systems that cannot be easily inhibited without lesioning brain…

Four pigeons were trained in a series of two-component multiple schedules. Reinforcers were scheduled with random-interval schedules. The ratio of arranged reinforcer rates in the two components was varied over 4 log units, a much wider range than previously studied. When performance appeared stable, prefeeding tests were conducted to assess…

In a typical transposition task, an animal is presented with a single pair of stimuli (for example, S3+S4-, where plus and minus denote reward and nonreward and digits denote stimulus location on a sensory dimension such as size). Subsequently, an animal is presented with a testing pair that contains a previously reinforced or nonreinforced…

For those who want to change the world, the author suggests they take the first step by learning about humane education. The goal of humane education is to graduate a generation of solutionaries. Humane education is founded upon the belief that human rights, environmental preservation, and animal protection are integral aspects of a just,…

The current study examines 3- and 5-year-olds' representation of the concept we label "animal" and its two nested concepts--"animal"[subscript contrastive] (including only non-human animals) and "animal"[subscript inclusive] (including both humans and non-human animals). Building upon evidence that naming promotes object categorization, we…

Approximately one-fourth of the population of Sweden will suffer from mental health problems at some point in their lives. This article shares a case study of collaboration between Jamtli Museum and a local hospital (K2) that aimed to provide adult learning opportunities for people with diverse mental health issues. Findings show some differences…

Reading assistance dogs can be incorporated into reading programs to increase a child's desire and ability to read. However, more data is needed to demonstrate the effectiveness of such programs. A 5-week reading assistance dog program was implemented to assess feasibility and effectiveness. Participants included 18 children entering the 2nd grade…
