English Learners (ELs), students from non-English-speaking backgrounds, are a fast-growing, understudied, group of students in the U.S. with unique learning challenges. Cognitive flexibility—the ability to switch between task demands with ease—may be an important factor in learning for ELs as they have to manage learning in their non-dominant language and access knowledge in multiple languages. We used functional MRI to measure cognitive flexibility brain activity in a group of Hispanic middle school ELs (N = 63) and related it to their academic skills. We found that brain engagement during the cognitive flexibility task was related to both out-of-scanner reading and math measures. These relationships were observed across the brain, including in cognitive control, attention, and default mode networks. This work suggests the real-world importance of cognitive flexibility for adolescent ELs, where individual differences in brain engagement were associated with educational outcomes.  相似文献

Open government     
Access to government information in electronic form is essential to the realization of a civil society, democratization, and a rule of law. Freedom of information issues are centrally important in countries around the world, and the Internet's World Wide Web offers the potential to provide freedom of information at low cost. Achieving a sound information policy to promote open government requires constant vigilance by those who care about the goal. The greatest threat is state sponsored monopoly. State sponsored monopolies are inimical to open government and rule of law because they open the possibility of censorship, because they raise prices and increase cost, and because they deprive the public of new technology developments. Agencies should never seek to restrict redissemination or to prescribe prices at which information may be distributed to redisseminated. Copyright law may be interpreted to exclude the possibility of copyright in basic public information. Finally, the proposed database protection treaty now pending before the World Intellectual Property Organization should be opposed, unless drafters add a compulsory license provision to mandate multiple sources and channels for public information locked up by intellectual property and database rights.  相似文献

The purpose of this study was to understand academic leadership's views of the field of school psychology. This is the first study that has attempted to incorporate the views of historically Black college and university (HBCU) Psychology Department Chairs' regarding the field of school psychology and the potential development of school psychology programs at HBCUs. The results indicated that Department Chairs at HBCUs are not recommending the field of school psychology to their students based on a variety of reasons related to their views of the field (e.g., lack of focus on Black research issues). Despite the shortage of school psychologists and ample career opportunities, Department chairs in our sample do not recommend the field of school psychology as a first option graduate school choice. Implications are discussed in terms of increasing the number of African Americans in the field of school psychology.  相似文献
