OBJECTIVE To evaluate the knowledge on developmental dysplasia of the hip (DDH) by professionals involved in its diagnosis. METHODS This is a cross-sectional study using questionnaires to assess the knowledge about DDH. Orthopedic surgeons and pediatricians, residents and medical students from a tertiary teaching hospital were included in the study. RESULTS We evaluated 142 medical students...

Retrieval practice improves retention of information on later tests. A question remains: When should retrieval occur during learning-interspersed throughout study or at the end of each study period? In a lab experiment, an online experiment, and a classroom study, we aimed to determine the ideal placement (interspersed vs. at-the-end) of retrieval practice questions. In the lab experiment, 64 s...

OBJECTIVE This study aims to propose a framework for measuring the degree of public health-sensitivity of patent legislation reformed after the World Trade Organization's TRIPS (Trade-Related Aspects of Intellectual Property Rights) Agreement entered into force. METHODS The methodology for establishing and testing the proposed framework involved three main steps:(1) a literature review on TRI...

New approaches are required to analyse very large land-use transportation systems in which millions of people make millions of trips each day. New computer technology has enabled packages that model very large transportation systems. Some of these models are reviewed and it is concluded that the TRANSIMS system developed at Los Alamos National Laboratory has the best combination of desirable ch...

The optimisation of undulatory underwater swimming is highly important in competitive swimming performance. Nineteen kinematic variables were identified from previous research undertaken to assess undulatory underwater swimming performance. The purpose of the present study was to determine which kinematic variables were key to the production of maximal undulatory underwater swimming velocity. K...

The present study investigated the degree to which an infants' use of simultaneous gesture-speech combinations during controlled social interactions predicts later language development. Nineteen infants participated in a declarative pointing task involving three different social conditions: two experimental conditions (a) available, when the adult was visually attending to the infant but did no...

OBJECTIVE To describe changes in reported influenza activity associated with the 2009 H1N1 pandemic in European countries and determine whether there is a correlation between these changes and completeness of national strategic pandemic preparedness. DESIGN A retrospective correlational study. SETTING Countries were included if their national strategic plans had previously been analysed and...

Individuals possessing absolute pitch (AP) are able to identify a given musical tone or to reproduce it without reference to another tone. The present study sought to learn whether this exceptional auditory ability impacts visual perception under stimulus conditions that provoke visual competition in the form of binocular rivalry. Nineteen adult participants with 3-19 years of musical training ...

Nineteen species of larval mosquitoes were collected from 209 sites in 47 of West Virginia's 55 counties over a 7-month period (April-October) in 1992. Aedes abserratus is recorded from the state for the first time.
