The nucleus accumbens is critical for reward-guided learning and decision-making. It is thought to "gate" the flow of a diverse range of information (e.g., rewarding, aversive, and novel events) from limbic afferents to basal ganglia outputs. Gating and information encoding may be achieved via cross-frequency coupling, in which bursts of…

The major challenge in laboratory teaching is the application of abstract concepts in simple and direct practical lessons. However, students rarely have the opportunity to participate in a laboratory that combines practical learning with a realistic research experience. In the Bioengineering Department, we started an experiential laboratory…

Background: Perimenstrual syndrome (PMS) among women with an intellectual disability (ID) has not been investigated in Taiwan. This study explores the prevalence/severity of PMS experienced by women with ID who are institutionalised. Method: Ninety two female residents aged 15 to 54 at six public institutions completed a structured interview…

One of the strengths of a virtual environment is the ability to immerse the occupant into an environment that would otherwise be impossible. The primary focus of the author's project in Second Life is to take advantage of this opportunity to explore novel approaches to medical education. Second Life can be used to model doctor-patient interaction,…

Students in practical nursing programs require 32 weeks of coursework (1 academic year) and completion of a national licensing exam (NCLEX-PN) to secure employment. The purpose of this study was to identify selected academic variables that were related to NCLEX-PN performance for first-time test takers of two types of practical nursing programs at…

We draw on the theory of allostasis to develop an integrative model of the current stress process that highlights the brain as a dynamically adapting interface between the changing environment and the biological self. We review evidence that the core emotional regions of the brain constitute the primary mediator of the well-established association…

This study examined the direct and interactive effects of stress reactivity and family adversity on socioemotional and cognitive development in three hundred and thirty-eight 5- to 6-year-old children. Neurobiological stress reactivity was measured as respiratory sinus arrhythmia and salivary cortisol responses to social, cognitive, sensory, and…

Objective: In this randomized noninferiority study, the effectiveness and efficiency of stepped care for chronic fatigue syndrome (CFS) was compared to care as usual. Stepped care was formed by guided self-instruction, followed by cognitive behavior therapy (CBT) if the patient desired it. Care as usual encompassed CBT after a waiting period.…

Objective: This study investigated the association between hostility and health and whether it is moderated by the quality of an individual's primary romantic relationship. Method: Longitudinal data were provided by 184 African Americans, including 166 women. Participants averaged 38 years old and were married or in long-term marriagelike…

"Highly iconic" structures in Sign Language enable a narrator to act, switch characters, describe objects, or report actions in four-dimensions. This group of linguistic structures has no real spoken-language equivalent. Topographical descriptions are also achieved in a sign-language specific manner via the use of signing-space and…

The current study sought to determine the relationship among music teachers' length of teaching experience, specialty (vocal or instrumental), and ratings of behaviors and teaching activities related to vocal health. Participants (N = 379) were experienced (n = 208) and preservice (n = 171) music teachers, further categorized by specialty, either…

The Symptom Validity Scale (Minnesota Multiphasic Personality Inventory-2-FBS [MMPI-2-FBS]) is a standard MMPI-2 validity scale measuring overstatement of somatic distress and subjective disability. Some critics assert the MMPI-2-FBS misclassifies too many medically impaired persons as malingering symptoms. This study tests the assertion of…

In the present article, I report on my experience in teaching and learning physiology in the first year of a new modular curriculum at the Faculty of Medicine of the National University of Rwanda. With self-reported questionnaires, I collected learning experience perceptions from 112 students who attended the module of physiology in 2008. The…

I recently had a cardiac stress test. It was my fourth. Its purpose was to determine whether my heart is pumping an adequate quantity of blood during exercise. Additionally, is there a partial arterial blockage or damaged heart muscle? The test involves the patient receiving an injection of Cardiolite[R], a substance containing a molecule to which…

Numerous articles have been published on the merits of active learning, and collectively they present a body of compelling evidence that these methods do enhance learning. In presenting arguments for active learning, it is often suggested that the traditional didactic lecture is more passive in nature and less effective as a teaching tool.…
