OBJECTIVE This study aimed to examine the differences in personality characteristics between adolescents with and without Internet addiction and substance use experience as defined by the Tridimensional Personality Questionnaire (TPQ), and to compare personality characteristics among groups of adolescents with both Internet addiction and substance use experience (comorbid group), those with onl...

ThefPDB\(" Planar Doped B_arrier| diode is a device consisting of a p doping spike \v .' between two" intrinsic layers and n ohmic contacts. This device has the advantages of controllable barrier height, diode capacitance and forward to reverse current ratio. A symmetrically designed PDB has an anti-symmetric current vs. voltage characteristic and is ideal for use as millimeter wave subharmonic...

OBJECTIVE To examine the prevalence of, and mothers' self-reported reasons for, introducing solid foods to infants earlier than recommended (aged <4 months) and the variation in reasons for early introduction by milk feeding type. METHODS The study included 1334 mothers who participated in the national longitudinal Infant Feeding Practices Study II (2005-2007). Monthly 7-day food-frequency qu...

The characteristics of referees and the potential subsequent effects on the peer-review process are an important consideration for science since the integrity of the system depends on the appropriate evaluation of merit. In 2006, we conducted an online survey of 1334 ecologists and evolutionary biologists pertaining to the review process. Respondents were from Europe, North America and other re...

The molecular mechanisms of intervertebral disc degeneration (IDD) remain elusive. We found that miR-155 is down-regulated in degenerative nucleus pulposus (NP), and more severe degeneration is correlated with higher matrix metallopeptidase 16 (MMP-16) expression. MMP-16 also degraded matrix aggrecan. Here, we addressed the in vivo miR-155-mediated pathological impact on IDD using a classic pun...

As the number of Australians engaging in short-term international travel increases, so does the opportunity for importing overseas-acquired infectious diseases. This study aimed to determine knowledge of infectious disease risks and pre-travel health advice (PTHA) seeking behaviour among Western Australians travelling to Bali, Indonesia or Thailand. Passengers departing from Perth International...

Spectral weighting strategies using a correlational method [R. A. Lutfi, J. Acoust. Soc. Am. 97, 1333-1334 (1995); V. M. Richards and S. Zhu, J. Acoust. Soc. Am. 95, 423-424 (1994)] were measured in ten listeners with sensorineural-hearing loss on a sentence recognition task. Sentences and a spectrally matched noise were filtered into five separate adjacent spectral bands and presented to liste...
