Road traffic noise and children's inattention
BACKGROUND: An increasing number of children are exposed to road
traffic noise levels that may lead to adverse effects on health
and daily functioning. Childhood is a period of intense growth
and brain maturation, and children may therefore be especially
vulnerable to road traffic noise. The objective of the present
study was to examine whether road traffic noise was associated
with reported inattention symptoms in children, and whether this
association was mediated by sleep duration. METHODS: This study
was based on the Norwegian Mother and Child Cohort Study
conducted by the Norwegian Institute of Public Health. Parental
reports of children's inattention at age 8 were linked to
modelled levels of residential road traffic noise. We
investigated the association between inattention and noise
exposure during pregnancy (n = 1934), noise exposure averaged
over 5 years (age 3 to 8 years; n = 1384) and noise exposure at
age 8 years (n = 1384), using fractional logit response models.
The participants were children from Oslo, Norway. RESULTS: An
association with inattention at age 8 years was found for road
traffic noise exposure at age 8 years (coef = .0083, CI =
[.0012, .0154]; 1.2% point increase in inattention score per 10
dB increase in noise level), road traffic noise exposure average
for the last 5 years (coef = .0090, CI = [.0016, .0164]; 1.3%
point increase/10 dB), and for pregnancy road traffic noise
exposure for boys (coef = .0091, CI = [.0010, .0171]), but not
girls (coef = -.0021, CI = [-.0094, .0053]). Criteria for doing
mediation analyses were not fulfilled. CONCLUSION: Results
indicate that road traffic noise has a negative impact on
children's inattention. We found no mediation by sleep duration

Gender Differences in Intellectual Capital Research: An Exploratory Study
The study aims to explore whether gender differences in the intellectual capital research exist. The differences are mainly investigated with reference to authorship patterns, research loyalty, productivity, trends of authorship patterns and productivity, research methodologies and research topic relevance. The investigation is carried out through an exploratory research approach. Consistent with it, data are mainly analyzed through descriptive statistics and tests of difference. The investigation takes into consideration the papers published in the Journal of Intellectual Capital from 2007 to 2016 (ten years). The total number of papers used is 340. The Journal of Intellectual Capital was chosen because it can be considered one of the leading journal of the intellectual capital research. Data used for the investigation are collected, in part, from the Scopus database and, in part, by reading the papers. The author gender was attributed manually, on the base of the authorâ name. Main findings show that differences do not exist with reference to collaboration propensity and magnitude, research loyalty, average research productivity, research methodologies and research topic relevance. On the contrary, they show that a difference exists with reference to international collaboration propensity

Mesozoic rift magmatism in the North Sea region: Ar-40/Ar-39 geochronology of Scanian basalts and geochemical constraints
More than 100 volcanic necks composed of basanites and melanephelinites occur in Scania, southern Sweden, at the junction of two major tectonic lineaments, the Phanerozoic Sorgenfrei-Tornquist Zone (STZ) and the Proterozoic Protogine Zone. New Ar-40/Ar-39 isotope analyses of whole rock fragments of nine selected basalt necks suggest that the Mesozoic alkaline volcanism in the Scanian province commenced earlier than previously reported and comprised three separate volcanic episodes that span a total period of ca. 80 Myr: a first Jurassic (191-178 Ma), a second at the Jurassic/Cretaceous boundary (ca. 145 Ma), and a final middle Cretaceous episode (ca. 110 Ma). The new results allow for precise time correlations between eruption events in the Scanian and those in the North Sea volcanic provinces. The older, early Jurassic event in Scania is largely synchronous with that in the Egersund Basin and the Forties field whereas the event at ca. 145 Ma is correlated with activity in the Central Graben. These volcanic episodes also correlate in age with Kimmerian tectonic activity. Volcanic activity in the middle Cretaceous period has also been dated in the triple junction in the North Sea and offshore in the Netherland Sector. The correlation of basalt volcanism in Scania with the Egersund nephelinites strongly suggest that volcanism was triggered by repeated tectonic activity along the STZ. Geochemical data of alkaline mafic rocks in the Scanian and the North Sea volcanic provinces imply that different provinces have largely unique geochemical signatures in favour of a heterogeneous mantle in the North Sea volcanic region. However, basalts of different generations in one and the same province cannot be readily separated on the basis of geochemistry, suggesting that the same lithospheric mantle was the source of repeated volcanism over time in each province. The data suggest a low degree of melting of a volatile-bearing mantle lherzolite enriched in incompatible elements with the exception of the Forties basalts in the rift centre, produced by larger degree of melting and evolved by fractional crystallization
