The cognitive development of young dual language learners: A critical review

Dual language exposure and bilingualism are relatively common experiences for children. The present review set out to synthesize the existing research on cognitive development in bilingual children and to identify the gaps and the methodological concerns present in the existing research. A search of major databases for research conducted with typically developing, preschool-age dual language learners between 2000 and 2013 yielded 102 peer-reviewed articles. The existing evidence points to areas of cognitive development in bilingual children where findings are robust or inconclusive, and reveals variables that influence performance. The present review also identifies areas for future research and methodological limitations.     

Wild West Libraries: A Study of Southwest Kansas Public Libraries

Public Libraries developed and grew along with the United States. In southwest Kansas, money, materials, staffing, and distance have been factors in the growth of the public libraries, and they remain current factors as well. Library consortia have aided in this development and have helped solve small library problems. This article reports a 2008 survey of public libraries that are served by the Southwest Kansas Library System (SWKLS). The survey lays out the operating conditions of some of America's small libraries and shows the extent of their interrelationship with their consortium.     

Schooling and Learning in U.S.-Mexican Families: A Case Study of Households

Recent research indicates that learning and the academic performance of Mexican-American students are influenced by the interplay of economic, cultural, linguistic, and educational factors. In this work, a household analysis is used to illustrate how students' schooling and academic achievement are influenced by household members' activities at home, in the community, and in the schools. The study reports that a household analysis help us understand the relative weight of these factors in shaping students' school performance, and that it also accounts for differential academic achievement in any Mexican-American community. This household analysis indicates that level of family stability and the social and economic conditions of poor communities are the strongest factors affecting students' learning and academic achievement.     

The role of habituation of the response to LiCl in the US-preexposure effect

In two experiments, rats received preexposure consisting of six intraperitoneal injections of lithium chloride (LiCl). This treatment reduced the magnitude of the unconditioned response (UR; suppressed consumption of a novel flavor) evoked by an additional injection (Experiment 1) or by oral consumption (Experiment 2) of LiCl. In both experiments, preexposure also attenuated the acquisition of a conditioned aversion with an LiCl injection as the unconditioned stimulus (US) but had no effect on the aversion produced when the US was oral consumption of LiCl (Experiment 2). These results are consistent with the view that the reduced ability of the preexposed US to serve as a reinforcer depends on blocking by injection-related cues and is independent of habituation of the UR recorded in the present study. Possible interpretations of this dissociation are discussed.     

Diagnosis and Treatment of Children with Reading and Writing Difficulties in Poland

IN POLAND the problem of specific difficulties in learning to read and write was noticed before the Second World War. Multidisciplinary investigations began in the 1950s. Our concepts of special difficulties of reading and writing are based on Luria, Konorski, Tomaszewski and Spionek's theories. Multidisciplinary examinations in diagnosis are employed and a system of therapeutic care is provided which includes small correction‐compensation groups, special grades, the ward for dyslexic children and individual treatment in outpatient clinics. Current work is focussing on the prevention of special learning difficulties.     

Challenges in the conservation of the work of León Ferrari

When dealing with contemporary art, conservators have to address not only the material aspects of the artwork but also other highly complex issues. The Argentinian artist Leon Ferrari is a representative example. He created avant-garde art installations but also worked with traditional techniques. His works raise dilemmas over concepts such as authorship, authenticity, legitimacy of art. Some of his artworks only interested him as a means to express his opinions and he was not concerned about alterations in their appearance. Therefore, what should be kept in them is not in an area of certainty for conservators. An essential key for achieving a responsible and respectful conservation result, is to understand the ideology involved in each ‘art piece’ created by Ferrari.
