We investigated whether children who were learning to read simultaneously in English and French activate phonological representations from only the language in which they are reading or from both of their languages. Children in French Immersion programs in Grade 3 were asked to name aloud cognates, interlingual homographs, interlingual homophones, and matched control words. Half of the participants performed the task in English, their first oral language, and half performed the task in French. Control monolingual children in each language were also tested. In the French reading task, fewer errors were observed for cognates and interlingual homophones than for matched control words, whereas more errors were produced for interlingual homographs than matched controls. Only the inhibitory interlingual homograph effect was observed in the English reading task. These data provide evidence that phonological activation in bilinguals is not language selective. The locus of each of these effects in the bilingual word recognition system is discussed. 相似文献

Using performance level box-office receipts from the PacificConservatory of the Performing Arts over eight years, we analyzeperformance-level demand for live theater. The disaggregated data allowsus to estimate demand at a particular venue and to characterize theseasonality of demand for live theater. We examine whether the supply ofshows matches the differentiated tastes of theater-goers at each of thethree locations and the sensitivity of demand to critical reviews andprior attendance. 相似文献

The requirements for paints used on outdoor sculpture and military vehicles are similar: overall protection for the underlying substrate, and the ability to withstand prolonged outdoor exposure and recurring physical contact. Aesthetic requirements are different but stringent for both categories of coatings and include maintaining appearance over time. Building on prior work undertaken by the United States Department of Defense (DoD) Army Research Laboratory (ARL) to modify military coating systems into a matte black paint suitable for outdoor sculpture, a long-term interdisciplinary collaboration is under way between the ARL, the Getty Conservation Institute, Mack Art Conservation, and NCP Coatings, that aims to develop and evaluate a wider range of robust paint systems with novel attributes for both the DoD and outdoor painted sculptures. For the latter, this includes coatings with a broader range of gloss, formulated with a much more varied palette. New low-gloss coatings used on military assets were used to paint sculptures by Alexander Calder, Tony Smith, and Louise Nevelson, designed to an aesthetic standard based on approved colour and gloss levels by the relevant artists’ foundations and estates, and formulated to enhance durability. These new coatings offer the ability to match or meet a range of artists’ aesthetic preferences, and to use a variety of polymeric flattening agents to control gloss levels, reduce marring, and eliminate volatile and hazardous pollutants. The use of low molecular weight (LMW) resins provides 4–8 hour pot life to assist in the application process. Compared to current resins, the LMW systems reduce organic solvent levels, are low viscosity, and permit far easier application. In addition, the replacement of typical pigments with low solar absorbing (LSA) pigmentation provides higher reflection which ‘shields’ the resin/binder system and reduces degradation. A particular advantage to conservators from this collaboration is that the coatings on DoD assets provide a convenient indicator of the paint's performance and durability. The outcome will be a unique coating system to provide enhanced durability and maintain the original coating properties for a period of 6–10 years. 相似文献

Although children with emotional and behavioural disorders (EBD) demonstrate significant difficulties in academic achievement including reading, little attention has been placed on effective reading instructional practices for this population of students. The purpose of this article is to briefly review the knowledge base of early reading instruction and the deep gaps in the research literature on how reading is taught to students with EBD. Finally, we will summarise several completed and ongoing research efforts that inform us of the instructional status quo for students with EBD in reading and efforts to improve academic outcomes for this population. 相似文献

We propose and evaluate a framework supporting collaborative discovery learning of complex systems. The framework blends five design principles: (1) individual action: amidst (2) social interactions; challenged with (3) multiple tasks; set in a (4) a constrained interactive learning environment that draws attention to (5) highlighted target relations. The framework addresses a persistent tension in discovery-based pedagogy between offering students the freedom to initiate, experiment, and explore and providing them with tailored experiences with many instances of particular relations underlying the target conceptual structure. The framework was realized with TrafficJams, a participatory simulation in which students drive together. A class of high-school students worked with TrafficJams over 2.5 h. The teacher’s role was to orchestrate the activity but there was no explicit instruction of the traffic and complexity principles. The students completed pre- and post-test questionnaires and their activities were observed and logged. In terms of driving in the simulation, the students learned to drive in ways that reduced congestion in traffic by decreasing lane and speed changes, and keeping their speed down. Even though there was no explicit teaching, half of the students learned that car speed distribution alone can generate traffic jams with no additional causes; and, keeping a safe following distance from the next driver increases everyone’s speed. Our study suggests that the learning environment partially met both the overarching design goal of constrained discovery and the specific content goal of systems reasoning. 相似文献
