Effect of contextual variables on mealtime problem behavior in the natural environment
… variables (food type and texture or session pre-feeding) on mealtime behavior. Research with problem behavior occurring outside of mealtime suggests that problem behavior may often be under the control of contextual or contextual variables. The purpose of this study was to further evaluate …

An Investigation into Establishing (Motivating) Operations
… pecks were made by hens maintained at 75% free-feeding bodyweight than hens maintained at 95% (different MO conditions). There were also higher levels of ineffective pecks in the 75% group. Experiment 5.1 investigated relative preference for stimuli correlated with different MO conditions: high …

Effects of Deprivation and Testing Procedures on Preference for Stimuli Correlated with Food Reinforcement Under Higher Deprivation Conditions in Mice
… studies have found that organisms appear to prefer stimuli correlated with food reinforcement under higher food deprivation levels relative to stimuli correlated with food under lower deprivation levels. This has led some researchers to assume a general relation between food deprivation level …

The Comparison of Airway Responses of Normal Horses Fed Round Bale versus Square Bale Hay
Background – Feeding horses round bale hay (RBH) has been associated with airway inflammation. The purpose of this study was to determine if horses fed RBH for a 6-week period demonstrated more evidence of airway inflammation than horses fed square bale hay (SBH) of comparable quality. Hypothesis - …

Persistence of response variation and repetition
… 20-s schedules operated in the initial links preceding each terminal link and lower response rates reliably occurred in the initial link preceding the Vary terminal link. After responding stabilized under the multiple chained schedule, four disruption conditions were employed, one condition in …

THE ABSENCE OF C3AR AND C5AR SIGNAL TRANSDUCTION PROMOTES T REGULATORY CELL DIFFERENTIATION AND REGULATES IMMUNOLOGIC TOLERANCE
… regulatory cells (iTregs). Endogenous TGF-ß1 suppresses C3aR and C5aR signaling by preventing C3a and C5a production and upregulating C5L2, an alternate C5a receptor. Absent C3aR and C5aR signaling decreases costimulatory molecule and IL-6 production and augments IL-10 production. The resulting …

Touchscreen Assessment of Motivation and Reinforcement-Related Choice Behaviour in Mice
… sensitivity are characteristic of depressive symptoms in a number of neuropsychiatric and neurodegenerative conditions. However, the efficacy of current therapeutic strategies is limited. Thus, the development of methods for studying these processes is important both to facilitate …

The ecology and feeding biology of thecate heterotrophic dinoflagellates
… was initiated, nothing was known about their feeding mechanisms, rates or food preferences. The population dynamics of these microheterotrophs were studied in a temperate estuary over a 13 month period, along with co-occurring diatoms, ciliates and pigmented (photosynthetic) dinoflagellates. …

Determination of the effects of pulse starches (pea, lentil and faba bean) versus cornstarch on growth performance and glucose tolerance in rainbow trout (Oncorhynchus mykiss)
… component of carbohydrate from ge-latinized and precooked cornstarch, gelatinized tapioca starch and gelatinized potato starch on fish growth. The overall effect size was 0.42 and P value was 0.65. The second meta-analysis examined the effect of glucose, maltose and dextrin on fish growth. The …
