Meta-analyses were performed on 12 studies of treatment with sexual offenders (N = 1,313). A small, but robust, overall effect size was found for treatment versus comparison conditions (r = .12). The overall recidivism rate for treated sexual offenders was .19 versus .27 for untreated sexual offenders. Treatment effect sizes across studies, however, were heterogeneous. Effect sizes were larger ...

A wave breaking against a sea wall causes high pressure gradients to act along the sea bed, pushing objects away from the wall. This situation is modelled using pressure impulse theory to show that, for a large object near a sea wall, the impulsive force due to the wave will move the object. This force can be found, given knowledge of the added mass and volume of an object. In particular, if th...

We consider a single-species model which is composed of several patches connected by linear migration rates and having logistic growth with a threshold. We show the existence of an aggregating mechanism that allows the survival of a species which is in danger of extinction due to its low population density. Numerical experiments illustrate these results. Ó 2000 Elsevier Science Inc. All rights ...

A critical question in cognitive science concerns how numerical knowledge develops. One essential component of an adult concept of number is ordinality: the greater than and less than relationships between numbers. Here it is shown in two experiments that 11-month-old infants successfully discriminated, whereas 9-month-old infants failed to discriminate, sequences of numerosities that descended...

To examine how the time course of rapid events of adaptation affect motion vision, the lower threshold of motion (LTM) was measured for suprathreshold sinusoidal gratings in presence of transient and steady glare. In the case of the transient condition, glare and stimulus were presented separated in time by a variable extent (SOA: 50–450 ms). A two alternative forced choice paradigm using the m...

Objectives: (i) To expose ‘normal sleepers’ to a 32-h sleep deprivation protocol and evaluate the impact of this deprivation on a complex performance task i.e. the paced auditory serial addition test (PASAT). (ii) To compare these sleep deprivation performance findings with historical data on the impact of sleepiness secondary to narcolepsy on PASAT performance measures. (iii) To investigate th...

Applying tabu search (TS) optimization technique to multimachine power system stabilizer (PSS) design is presented in this paper. The proposed approach employs TS to search for optimal or near optimal settings of PSS parameters that shift the system eigenvalues associated with the electromechanical modes to the left of a vertical line in the s-plane. Incorporation of TS algorithm in PSS design ...

To characterize the specificity of ion binding to phospholipids in terms of headgroup structure, hydration and lyotropic phase behavior we studied 1-palmitoyl-2-oleoyl-phosphatidylcholine as a function of relative humidity (RH) at 25 °C in the presence and absence of Li, Na, K, Be, Mg, Ca, Sr, Ba, Zn and Cu ions by means of infrared (IR) spectroscopy. All divalent cations and Li shift the gel-t...

P2X receptors are a family of ligand-gated ion channels, activated by extracellular ATP. The seven subunits cloned (P2X1–7) can assemble to form homomeric and heteromeric receptors. Peripheral neurons of neural crest origin (e.g. those in dorsal root, trigeminal, sympathetic and enteric ganglia) and placodal origin (e.g. those in nodose and petrosal ganglia) express mRNAs for multiple P2X subun...
