OBJECTIVES: To test Music Marker Theory (MMT) positing that early adolescents’ preferences for nonmainstream types of popular music indicate concurrent and later minor delinquency. METHODS: MMT was tested in a 4-year longitudinal study (n = 309). RESULTS: The results showed that early fans of different types of rock (eg, rock, heavy metal, gothic, punk), African American music (rhythm and blues...

The capabilities of the ventilation systems in the two road tunnels at Dartford (UK) are analysed using a multi-scale modelling approach. Both tunnels have complex semi-transverse ventilation systems with jet fans to control longitudinal flow. The construction and ventilation systems in the tunnels are described and the current emergency ventilation strategies are presented. The analysis includ...

Background Globally, soccer is the most popular team sport, unifying many fans all around the world. The epidemiological studies so far have confirmed that head playing and hitting the ball with head may cause minor head injuries, which exert their effects in a cumulative way. Methods Literature search for this review was conducted and data about traumatic brain injury collected from various ...

laboratory and field experiments were conducted to determine the efficacy of some insecticides on the control of sarta longhorned beetle, aeolesthes sarta solsky adults and larvae. in the laboratory, three pairs of mated and non-oviposited adults were released on the logs of field elm, ulmus minor mill that had been treated with chlorpyrifos, carbaryl, permethrin or imidacloprid. in the field e...

The fungal pathogen Aspergillus sydowii is causing high mortality of sea fan gorgonians Gorgonia ventalina in a Caribbean-wide outbreak. Fungal infection induces a localized band of melanin adjacent to fungal hyphae. We also detected an unidentified parasite that induced a similar melanin band, suggesting that melanization is a generalized response to infection. Although a common mechanism of a...

The Quaternary Geology of the eastern South Bend 30- x 60-Minute Quadrangle in Indiana represents landforms and near-surface sediments deposited during Wisconsin Episode, Late Pleistocene. Sediments reflect interplay between Saginaw Michigan Lobes Laurentide Ice Sheet. A relatively shallow, buried pre-Wisconsin mid-Wisconsin morphology has been overridden by advances leading to Last Glacial Max...

Heat waves continue to claim lives, with the elderly and poor at greatest risk. A simple and cost-effective intervention is an electric fan, but public health agencies warn against their use despite no evidence refuting their efficacy in heat waves. A conceptual human heat balance model can be used to estimate the evaporative requirement for heat balance, the potential for evaporative heat loss...

This paper accompanies a previous one [KS99] by D. Kramkov and the present author. While in [KS99] we considered utility functions U : R+ → R satisfying the Inada conditions U ′(0) = ∞ and U ′(∞) = 0, in the present paper we consider utility functions U : R → R which are finitely valued, for all x ∈ R, and satisfy U ′(−∞) =∞ and U ′(∞) = 0. A typical example of this situation is the exponential...
