The role of these new centres in transforming the inner cities of some of the UK＇s larger conurbations is examined and the key planning issues are discussed. The article concludes that the key principles of urban planning and control must still apply in shaping the role these new developments have in the UK＇s evolving urban landscape.展开更多

Educational processes without educational technology have no value in this modern world. In education domain, the educational software has simplified the processes in greater extend. A implemented while developing such educational software. In particu proper lar, the development methodology has to be software developed to enrich these education processes should follow a development strategy to motivate the end users to utilize the hypermedia potentials. The software development life cycle （SDLC） has different phases in designing such educationa technology and assists the end users to benefit from the modern technology. This study identifies the various factors to be considered at each phase of the SDLC while developing educational software. Also, this study proposes some suggestions to be followed in ESDLC with respect to educational processes perspectives. The core idea of this study is to identify the various issues in implementing such educational software in day to day teaching and learning processes.展开更多

Building on research from the field of computational neuroscience, the author provides an alternative understanding of what it means to be autistic and how to best support people on the autism spectrum to successfully adapt to the world in which we all live.展开更多

A Medline search was performed for English-language articles cross-referencing CDH with pertinent search terms. Retrospective, prospective, and longitudinal follow-up studies were examined. The reference lists of identified articles were also searched. Neurodevelopmental dysfunction has been recognized as one of most common and potentially most disabling outcome of CDH. Intelligence appears to be in the low normal to mildly delayed range. Neuromotor dysfunction is common during early childhood. Behavioral problems, hearing impairment, and quality of life related issues are frequently encountered in older children and adolescence. Disease severity correlates with the degree of neurological dysfunction. Neurodevelopmental follow-up in CDH children should become standard of care to identify those who would benefit from early intervention services and improve neurological outcomes.展开更多
