The development and validation of the beliefs about Baby Crying at Night (BBCN) scale.

Objective: What are young children trying to express when they cry at night? According to Sadeh, parental beliefs about why their child is crying may play a role in the development and persistence of their child's insomnia. The aim of this study was to create a scale that specifically assesses these parental interpretations in different dimensions.

Methods: Children aged between 6 months and 3 years with either good sleep habits or behavioural insomnia were recruited.

Cross-national Psychometric Evaluation of the Jefferson Scale of Empathy-Medical Student Version.

This study aimed to examine the factorial structure of the Jefferson Scale of Empathy-Medical student version (JSE-S) and assess items' discriminatory ability at higher and lower empathy levels in medical student populations from different countries and languages. JSE-S datasets were retrieved from previous studies of 4113 first- and/or second-year medical students from Switzerland, Portugal, Italy, Brazil, France, Spain, New Zealand, UK, Ireland, Mexico, and Peru. Parallel principal component analyses and item response theory were applied.

[Erionite, an exposure factor linked to pleural mesothelioma].

Mesotheliomas are neoplasia developed from the mesothelium, a layer covering the viscera (visceral layer) and the cavity where the organs are (parietal layer). The best known, and the most frequently encountered is the pleural mesothelioma. This disease has a close link with exposure to asbestos, a mineral fibre now banned in several countries.

Limitations and insights regarding atmospheric mercury sampling using gold.

Background: Atmospheric mercury (Hg) concentrations are quantified primarily through preconcentration on gold (Au) cartridges through amalgamation and subsequent thermal desorption into an atomic fluorescence spectrometry detector. This procedure has been used for decades, and is implemented in the industry-standard atmospheric Hg analyzer, the Tekran 2537. There is ongoing debate as to whether gaseous elemental mercury (Hg) or total gaseous mercury (TGM, Hg + Hg) is measured using Au cartridges.

Measurement of Atmospheric Mercury: Current Limitations and Suggestions for Paths Forward.

Mercury (Hg) researchers have made progress in understanding atmospheric Hg, especially with respect to oxidized Hg (Hg) that can represent 2 to 20% of Hg in the atmosphere. Knowledge developed over the past ∼10 years has pointed to existing challenges with current methods for measuring atmospheric Hg concentrations and the chemical composition of Hg compounds. Because of these challenges, atmospheric Hg experts met to discuss limitations of current methods and paths to overcome them considering ongoing research.
