    Notes: Applying a dc electric field across a fused silica sample at elevated temperatures followed by cooling the sample with the field applied (thermal poling) leads to a second-order nonlinearity that has been linked to the formation of a space-charge region in bulk glass. The first microscopic information on the extent of the space-charge region and its behavior with poling time is reported using secondary ion mass spectrometry to monitor the distribution of charged impurities. Lithium and sodium ions are observed to form depletion regions. Potassium and sodium ions as well as a hydrogenated species appear to be injected from the surface. The extent of the space-charge region evolves approximately logarithmically with poling time well after the nonlinearity as measured by second-harmonic generation has been established. The evolution of the space charge region can be qualitatively understood by an ion-exchange model that allows interaction of two ionic carriers with vastly different mobilities. © 1999 American Institute of Physics.

    Dopamine Agonist-Induced Inhibition of Neurotransmitter Release from the Awake Squirrel Monkey Putamen as Measured by Microdialysis (1997)

    Notes: Abstract: Male squirrel monkeys (Saimiri sciureus) were surgically prepared with cranial guide cannulae for acute microdialysis sampling of the putamen nucleus, a dopamine (DA)-rich brain region. On the day of an experiment, an animal was placed in a Plexiglas restraining chair and a microdialysis probe was inserted through the guide into the putamen. Perfusates of artificial cerebrospinal fluid were collected every 20 min over several hours and analyzed via HPLC with electrochemical detection. DA D2/D3 agonist drugs were administered either orally (p.o.) or subcutaneously (s.c.), and changes in levels of DA in the dialysates were measured. All of the drugs tested, i.e., quinpirole (0.5 mg/kg p.o.), talipexole (0.75 mg/kg p.o. or s.c.), and PD 135222 (7 mg/kg p.o.), decreased spontaneous DA overflow by ∼40–50% during the first 2 h following dosing. In animals that routinely underwent the microdialysis procedure up to 23 times over a 2-year period, there was neither an appreciable change in basal DA overflow nor a significant change in the magnitude of drug response. These data suggest that DA D2/D3 agonists attenuate DA neuronal overflow in the primate brain, similar to effects seen in rodents. Furthermore, these results also demonstrate the utility of repeated intracerebral microdialysis as a tool to monitor dynamic changes in neurochemical activity in monkeys over a prolonged period of time.

    Quasi-autistic Patterns Following Severe Early Global Privation (1999)

    Notes: Six per cent of child in a sample of 111 children who were adopted into U.K. families from Romania, and who were systematically assessed at the ages of 4 and 6 years, showed autisticlike patterns of behaviour. A further 6% showed milder (usually isolated) autistic features. Such autistic characteristics were not found in a similarly studied sample of 52 children adopted in the first 6 months of life within the U.K. The children from Romania with autistic patterns showed clinical features closely similar to “ordinary” autism at 4 years but they differed with respect to the improvement seen by age 6 years, to an equal sex ratio, and to a normal head circumference. The children from Romania with autistic features tended to differ from the other Romanian adoptees with respect to a greater degree of cognitive impairment and a longer duration of severe psychological privation.

    OXYGEN SAG EQUATION FOR THREE-HALVES ORDER BOD REACTION (1999)

    Notes: Several published BOD data sets are examined to show that approximately half of them are described best in the least squares sense by treating the BOD equation as being of the three-halves order instead of first order. A dissolved oxygen (DO) sag equation for a stream is developed in which the BOD is described as a three-halves order reaction. The time when the minimum DO concentration occurs is calculated numerically. The DO sag model applied to example problems shows that an increase in the BOD reaction rate constant results in a smaller minimum DO concentration and a decrease in the time to reach the minimum DO.

    Intra-Individual Differences and Relationship-Specificity of Mentalising in Early Adolescence (1999)

    Notes: There is increasing interest in understanding how relationships promote children’s understanding of their own and others’ thoughts and feelings. A key question in this research is whether children’s ability and motivation to represent and nderstand anothers’ thoughts and feelings is a function of the quality of the relationship with that individual or, alternatively, a more general characteristic of the child that is similarly expressed across relationship contexts. The current study sought to extend previous research by assessing mentalising behaviour in early adolescence and examining intra-individual differences in adolescents’ mentalising behaviour about self and other in different relationships. The research design exploited the natural experiment of the secondary school, in which children develop very diverse relationships with different teachers. In the spring of the academic year, a vignette-based, semi-structured interview was administered, and students’ understanding and attributions of mental states of their most and least liked teachers were coded using a newly developed system. Results indicated that there were significant intra-individual differences in adolescents’ mentalising; the psychological sophistication with which adolescents understood and described another’s behaviour was predicted from the affective quality of the relationship. In addition, there was significantly less incongruity or distortion in adolescents’ mentalising about their most liked teacher compared with their least liked teacher, highlighting the need to consider not only the presence but also the ‘accuracy’ of mentalising.
