Polymer nanocomposites for microactuation and magneto-electric transduction

In the last decade, electroactive polymers have attracted much attention especially because of their very actuating capabilities. Large strain is experimentally observed, but under quite high electrical field, which can be a severe drawback for actuating applications. First part of the present paper is concerned with the reduction of applied field onto electroactive polymer films to get a given strain level. Polyurethane (PU) films filled with carbon black (CB) nanoparticles exhibit relatively high strain level under a field of only 12.5 kV/mm. The simple easy-tomake method solution cast method was applied. Even though the generated stress level is still quite low, the present work shows high strain level under quite low field appliance by easy manufacturing, lightweight, and flexible polymer film. Besides, another interest of the present paper is in magneto-elasto-electric effect of a polymer film filled with some magnetic nano particles. Films filled with nonpiezoelectric but with magnetite particles has still short history. With the use of magneto materials, a large magnetic DC bias field is generally required, and it causes big problem on application. The films filled with some magnetite nanoparticles (Fe3O4 and Nickel) are fabricated then examined. It is clearly demonstrated that our films do not require any DC bias. Although linear polarization value is relatively small, the first step of the studies on magnetite nano-filled film is presented.     

The development of automatic numerosity processing in preschoolers: Evidence for numerosity-perceptual interference.

Three experiments examined developmental changes in the automatic processing of numerosity and perceptual information using a nonsymbolic numerical Stroop paradigm. In Experiments 1 and 2 (E1 and E2), 4-, 5-, and 6-year-olds had to compare the numerosities or the total filled areas of collections of dots (E1) or bars (E2) varying along both dimensions. Experiment 3 replicated E2's results in 3-, 4-, and 5-year-olds. Results demonstrated the existence of reciprocal influences between numerical and perceptual information beginning at age 3. Moreover, the irrelevant perceptual influences remained stable throughout development, whereas the sensitivity to irrelevant numerical cues tended to increase with age despite children's growing inhibition capacities. No significant correlation could be found between these developmental changes and the acquisition of counting knowledge. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of syntactic expectations on speech segmentation.

Although the effect of acoustic cues on speech segmentation has been extensively investigated, the role of higher order information (e.g., syntax) has received less attention. Here, the authors examined whether syntactic expectations based on subject-verb agreement have an effect on segmentation and whether they do so despite conflicting acoustic cues. Although participants detected target words faster in phrases containing adequate acoustic cues ("spins" in take spins and "pins" in takes pins), this acoustic effect was suppressed when the phrases were appended to a plural context (those women take spins/*takes pins [with the asterisk indicating a syntactically unacceptable parse]). The syntactically congruent target ("spins") was detected faster regardless of the acoustics. However, a singular context (that woman *take spins/takes pins) had no effect on segmentation, and the results resembled those of the neutral phrases. Subsequent experiments showed that the discrepancy was due to the relative time course of syntactic expectations and acoustics cues. Taken together, the data suggest that syntactic knowledge can facilitate segmentation but that its effect is substantially attenuated if conflicting acoustic cues are encountered before full realization of the syntactic constraint.

Less Guilty by Reason of Adolescence: Developmental Immaturity, Diminished Responsibility, and the Juvenile Death Penalty.

The authors use a developmental perspective to examine questions about the criminal culpability of juveniles and the juvenile death penalty. Under principles of criminal law, culpability is mitigated when the actor's decision-making capacity is diminished, when the criminal act was coerced, or when the act was out of character. The authors argue that juveniles should not be held to the same standards of criminal responsibility as adults, because adolescents' decision-making capacity is diminished, they are less able to resist coercive influence, and their character is still undergoing change. The uniqueness of immaturity as a mitigating condition argues for a commitment to a legal environment under which most youths are dealt with in a separate justice system and none are eligible for capital punishment.

Self-Perceptions of Competence in Children With ADHD and Comparison Children.

The self-perceptions of children with attention-deficit/hyperactivity disorder (ADHD; n=487) were compared with those of children in a local normative comparison group (n=287), relative to teacher- and parent-rated perceptions of their competence. Children were participants in the ongoing follow-up portion of the Multimodal Treatment Study of Children with ADHD. Children with ADHD were much more likely than comparison children to overestimate their competence relative to adult report, regardless of who was used as the criterion rater (teacher, mother, or father). Examination by comorbidity subgroups revealed that children with ADHD inflated their self-perceptions the most in domains of greatest deficit. Gender effects also are reported.

Civilian post-traumatic stress disorder: Clinical syndromes and psychotherapeutic strategies.

Reviews the clinical features of the major classes of civilian PTSD that psychotherapists are most likely to encounter including medical procedures, pain, crime and the social environment, traffic accidents, traumatic brain injury, and the toxic stress syndrome. Psychotherapeutic strategies that clinicians can productively employ to treat civilian PTSD are discussed including supportive therapy, behavioral approaches, and psychodynamic psychotherapy.

Recycled and re-used plastics for food packaging?

The draft European Commission directive on packaging and packaging waste sets ambitious targets for recovery and states that recycle must contribute an important part of recovery. To meet these targets, there will inevitably be pressure to recycle plastics back into food contact uses. This legislative driving force is coupled with considerable consumer pressure. However, it must be accepted that there will be many, perhaps even a majority, of food applications where recycle or re-use of plastics is not desirable and these plastics must be put to alternative uses. Protection of the environment must not be at the expense of public health. This paper outlines the issues involved and describes a multi-centre European project that aims to define criteria to ensure the quality and safety-in-use of recovered plastics for food contact.
