Solhjoo, Kavous - - 2010
Problem statement: In situations of immunodeficiency, Toxoplasma gondii emerges as a life-threatening infection. Toxoplasma gondii is transmitted parenterally, flourish in immunocompromised subjects and, most toxoplasma infections are asymptomatic. Studies have shown that there is a immunodeficiency in renal failure patient such as hemodialysis patients and these patients have a high ...

Problem statement: Fetal loss and abortion are responsible for significant emotional distress for couples desiring children. There are many documents which support the role of some certain asymptomatic infections such as Cytomegalovirus (CMV) in spontaneous abortion. This study was aimed to evaluate the prevalence of seropositivity for CMV IgG and ...

Problem statement: The Tigecycline Evaluation and Surveillance Trial (TEST) commenced in 2004 to monitor the activity of tigecycline, a new glycylcycline and numerous comparators against major hospital-and community-associated pathogens. In this report we examine the efficacy of tigecycline and comparators against isolates of Staphylococcus aureus collected from blood. Approach: Almost ...

Published just over a half century ago, Schedules of Reinforcement (SOR) (Ferster & Skinner, 1957) marked the seminal empirical contribution of the book's second author and ushered in an era of research on behavior-environment relationships. This article traces the origins of both the methods and the data presented in SOR, ...
Moore, J. - - 2010
The philosophy of science is the branch of philosophy that critically examines the foundations, assumptions, methods, products, and implications of the activity called science. The present sketch reviews the historical development of the philosophy of science, representative individuals in the field, and topics of longstanding interest The sketch is intended ...
Pulido, Marco - - 2010
The present study assessed the effects of systematically separating the cue from the response in temporally defined schedules of delayed signaled reinforcement. Identical schedules were used to study the effects of the independent variable on response acquisition and response maintenance. In the first experiment, 8 groups of 3 naive rats ...
Navarick, Douglas - - 2010
Students repeatedly chose between brief reinforcement (cartoon viewing) followed by a long time-out and extended reinforcement followed by a brief time-out. They infrequently chose the former schedule, which they rated as "unpleasant." Then they were instructed to choose only this subjectively aver-sive schedule. When participants were informed that leaving would ...

The Implicit Relational Assessment Procedure (IRAP) is a relatively new measure of implicit cognition that tests cognition as relational behavior instead of an associative activity and thus may provide a more specific measure of cognitive repertoires, including those for social biases, than better known implicit measures such as the Implicit ...
Barnes-Holmes, Dermot - - 2010
The current research comprised two experiments that employed the Implicit Relational Assessment Procedure (IRAP) as a measure of implicit racial attitudes. White Irish participants were exposed to blocks of trials that involved responding in a manner consistent with either a pro-white stereotype or a pro-black stereotype. In Experiment I, participants ...
Adcock, Amanda - - 2010
The present study examines whether facilitated acquisition occurs in contexts when 1 stimulus in a class is emotionally evocative and the other stimuli are arbitrary or neutral. Undergraduates with high and low grade-point averages (GPA) completed a matching-to-sample task that resulted in the formation of 3 stimulus equivalence classes. Each ...
Okouchi, Hiroto - - 2010
Five undergraduates responded under a fixed-ratio (FR) 145 schedule, and 5 others responded under a differential-reinforcement-of-low-rate (DRL) 20-s schedule. Both groups were then exposed to a differential-reinforcement-of-rates-with-pacing 1 s < interresponse time (IRT) [less than or equal to] 2 s schedule. Following this, probe sessions under fixed-interval (FI) 20-s, variable-interval ...
Garruto, Michelle - - 2010
Conditional discrimination or matching-to-sample procedures have been used to study a wide range of complex psychological phenomena with infrahuman and human subjects. In most studies, the percentage of trials in which a subject selects the comparison stimulus that is related to the sample stimulus is used to index the control ...
Knight, Kenneth - - 2010
Context: The purpose of study, experimental, or research design in scientific manuscripts has changed significantly over the years. It has evolved from an explanation of the design of the experiment (ie, data gathering or acquisition) to an explanation of the statistical analysis. This practice makes "Methods" sections hard to read ...
Hart, Joseph - - 2010
Context: Arthrogenic muscle inhibition is an important underlying factor in persistent quadriceps muscle weakness after knee injury or surgery.
Wham, George S., - - 2010
Context: Research suggests that appropriate medical care for interscholastic athletes is frequently lacking. However, few investigators have examined factors related to care.
Wilkerson, Gary - - 2010
Context: Excessive fat mass clearly has adverse effects on metabolic processes that can ultimately lead to the development of chronic disease. Early identification of high-risk status may facilitate referral for definitive diagnostic tests and implementation of interventions to reduce cardiometabolic risk.
Fritz, Julie - - 2010
Context: Back pain is common in adolescents. Participation in sports has been identified as a risk factor for the development of back pain in adolescents, but the influence of sports participation on treatment outcomes in adolescents has not been adequately examined.
Reinking, Mark - - 2010
Context: Prevention of exercise-related leg pain (ERLP) has not been successful because ERLP risk factors are not well known.
Thomas, Stephen - - 2010
Context: Conditions such as labral and rotator cuff injuries have been linked with decreases in glenohumeral internal-rotation and increases in external-rotation motion. Also, decreased glenohumeral internal rotation is strongly associated with scapular dyskinesis.
Higgins, Michael - - 2010
Context: Removal of the lacrosse helmet to achieve airway access has been discouraged based only on research in which cervical alignment was examined. No researchers have examined the effect of lacrosse equipment on the cervical space available for the spinal cord (SAC).
Cameron, Kenneth - - 2010
Context: Ankle sprains have been reported as one of the most common injuries sustained by members of the US Armed Services. However, little is known about the incidence rate and injury patterns associated with ankle sprains in this population.
Romani, William - - 2010
Context: Sex-specific responses to steroid sex hormones have been suggested as a potential cause for the disparate anterior cruciate ligament (ACL) injury rates between male and female athletes. Type 1 collagen (T1C) and type 3 collagen (T3C) are crucial structural components that define the ligament's ability to withstand tensile loads. ...
Telhan, Gaurav - - 2010
Context: Knowledge of the kinetic changes that occur during sloped running is important in understanding the adaptive gait-control mechanisms at work and can provide additional information about the poorly understood relationship between injury and changes in kinetic forces in the lower extremity. A study of these potential kinetic changes merits ...
Kulas, Anthony - - 2010
Context: Because anterior cruciate ligament (ACL) injuries can occur during deceleration maneuvers, biomechanics research has been focused on the lower extremity kinetic chain. Trunk mass and changes in trunk position affect lower extremity joint torques and work during gait and landing, but how the trunk affects knee joint and muscle ...
Sarker, M.S.K. - - 2010
This experiment was conducted on 60 Hanwoo calves comprising five feed additive groups, with 12 calves in each group, to determine the effects of additives at pre- and post-weaning on growth performance and blood profile. The groups were control, antibiotic (Neomycin 110 ppm), illite (2%), fermented green tea probiotics (FGTP, ...
