Counseling services are only likely to be effective if individuals are willing to seek help. Although much of the research on youth help-seeking has focused on adolescents, few studies have examined this in regard to children. Constant comparison analysis of focus group discussions revealed differences based on age and gender. Knowledge, sources of help, willingness, concerns regarding confidentiality, levels of interpersonal openness and stigma tolerance differed based on age. Gender differences were also highlighted. Implications focus on enhancing help-seeking among youth. 相似文献

The paper considers a class of neural networks where flux-controlled dynamic memristors are used in the neurons and finite concentrated delays are accounted for in the interconnections. Goal of the paper is to thoroughly analyze the nonlinear dynamics both in the flux-charge domain and in the current-voltage domain. In particular, a condition that is expressed in the form of a linear matrix inequality, and involves the interconnection matrix, the delayed interconnection matrix, and the memristor nonlinearity, is given ensuring that in the flux-charge domain the networks possess a unique globally exponentially stable equilibrium point. The same condition is shown to ensure exponential convergence of each trajectory toward an equilibrium point in the voltage-current domain. Moreover, when a steady state is reached, all voltages, currents and power in the networks vanish, while the memristors act as nonvolatile memories keeping the result of computation, i.e., the asymptotic values of fluxes. Differences with existing results on stability of other classes of delayed memristor neural networks, and potential advantages over traditional neural networks operating in the typical voltage-current domain, are discussed. 相似文献

In this work, the decision-making process involved in the restoration of the eighteenth century paliotto ligneo (wooden altar frontal) della chiesa del Santissimo Crocifisso all’Albergheria of Palermo is presented. Earlier research concerning mirror restoration was based on only a few case studies and the proposed techniques were not suitable for the artwork here. As a consequence, it was necessary to re-examine theories and protocols of modern restoration to plan an appropriate intervention of the altar frontal. Since in this artwork the role of mirrors is not to give back images, as usual, but rather to create special light effects and play of lights, this work aims to find an approach to the restoration of the altar frontal and its decorations that allows a homogeneous overview of the piece. Thus, the mirrors were not substituted or re-created. Only a visual integration of the damaged ancient mirrors was proposed, with the use of metallic-polymeric films, permitting a completely reversible restoration. 相似文献

We develop and test a dual-route model of genetic effects on reading aloud and spelling, based on irregular and non-word reading
and spelling performance assessed in 1382 monozygotic and dizygotic twins. As in earlier research, most of the variance in
reading was due to genetic effects. However, there were three more specific conclusions: the first was that most of the genetic
effect is common to both regular and irregular reading. In addition to this common variance evidence was found for distinct
genes influencing the acquisition of a lexicon of stored words, and additional genetic effects influencing the acquisition
of grapheme–phoneme correspondence rules. The third conclusion, from a combined model of reading and spelling, is that reading
and spelling have a common genetic basis. Models that did not distinguish lexical and non-lexical performance fit significantly
worse than dual route genetic models. An implication of the research is that models of reading, whether connectionist or dual-route,
must allow for the genetic independence of neurological processes underlying the decoding of non-words and irregular words. 相似文献
