The aim of this study was to assess the contents of medical textbooks, eMedicine (Medscape) topics, and YouTube videos on cardiovascular mechanisms. Medical textbooks, eMedicine articles, and YouTube were searched for cardiovascular mechanisms. Using appraisal forms, copies of these resources and videos were evaluated independently by three…

Medical school students are expected to learn many subjects at the same time. As a result, they often experience stress and find it difficult to cope with the curriculum. In addition, some first-year students find theory and practical classes to be monotonous. One of the difficulties faced by faculty members is, therefore, to maintain student…

Introduction: Stress suffered by adolescents is often neglected. In fact, there are very few measuring instruments that have been translated into Spanish for the assessment of stress manifestations in teenagers. Method: The main purpose of this work was to analyze the psychometric properties of the Student Stress Inventory-Stress Manifestations…

Presence may occur when actors are alert and relaxed in performance. A positive mood is associated with physical activity, but little is known about how movement qualities affect mood and vital signs of actors. This study examined the effects of vibratory, pendular, abrupt, and sustained movement qualities on the Brief Mood Introspection Scale,…

There is evidence supporting the social and cognitive benefits of music education. However aspects of music practice, such as an increase in frequency and intensity of practice, are associated with playing-related musculoskeletal problems in adult musicians, though with limited evidence in children. The aim of this study was to describe the music…

The Federal University of São Paulo, Baixada Santista Campus was founded in 2006 with five degree-granting programs in physical education, physiotherapy, nutrition, psychology, and occupational therapy. The guiding principle behind the programs' educational mission was centered on the development of health care professionals capable of working in…

This study examined the association between parenting stress, family functioning, child behavior problems, language development, mother's education, child's sex, child's age, and child's hearing device in a cross-sectional sample of 37 mothers with typical hearing who have children who are deaf and hard of hearing enrolled in early childhood…

Stan Metzenberg offers a critical analysis of the draft "Massachusetts Science and Technology/Engineering Standards," which are for pre-Kindergarten to Grade 8 and introductory high school courses. Metzenberg claims that the document reveals significant, unacceptable gaps in science content, as well as some notable errors and…

In two experiments rats were required to escape from a circular pool by swimming to an invisible platform that was located in the same place relative to one configuration of two landmarks (X and Y). The two landmarks were placed relatively far and equidistant from the hidden platform. Training could be either on consecutive days (Experiment 1) or…

Wind turbines generate low-frequency sounds that affect the ear. The ear is superficially similar to a microphone, converting mechanical sound waves into electrical signals, but does this by complex physiologic processes. Serious misconceptions about low-frequency sound and the ear have resulted from a failure to consider in detail how the ear…

This opinion statement points out some of the considerations and pitfalls in using virtual reality computer programs in the teaching of life sciences. Emphasis is placed on the possibility of such programs leading to reductionist thinking including how reductionist thinking could foster the formation of misconceptions. Negative feedback is used as…

Each of us as a scientist has an academic legacy that consists of our mentors and their mentors continuing back for many generations. Here, I describe two genealogies of my own: one through my PhD advisor, H. T. (Ted) Hammel, and the other through my postdoctoral mentor, Knut Schmidt-Nielsen. Each of these pathways includes distingished scientists…

Four meta-analyses examined relationships between morningness and cognitive ability (total N=2177), eveningness and cognitive ability (total N=1519), morningness and academic achievement (total N=3220), and eveningness and academic achievement (total N=700). The analyses focused on the population effect size (to reveal the effect across studies)…

Purpose: In this study, the authors investigated the effects of age on the use of fundamental frequency differences([delta]F[subscript 0]) in the perception of competing synthesized vowels in simulations of electroacoustic and cochlear-implant hearing. Method: Twelve younger listeners with normal hearing and 13 older listeners with (near) normal…

Schizophrenia is a chronic mental illness which poses a tremendous burden on the families, caregivers and the society. The purpose of this paper is to provide an updated review of the epidemiology of schizophrenia with a special attention to the clinically important risk factors such as drug abuse, hormonal factors and the new advances in genetic…
