Dimensionality of Writing Skills in English and Spanish, and the Relations of Language and Cognitive Skills to Written Composition for EnglishâSpanish Emergent Bilingual Children in Grade 1
We examined the relations of language skills (vocabulary, listening comprehension, and oral retell), transcription skills (spelling and handwriting fluency), and domain-general cognitions/executive functions (working memory and attentional control) to writing quality for English-Spanish emergent bilingual children in Grade 1. Data were from a convenience sample of 211 children (57% girls; 82% Hispanic, 9.5% White, 4% Asian American children) who were assessed on written composition, vocabulary, listening comprehension, oral retell, and spelling in English and Spanish; handwriting fluency and working memory in English; and attentional control rated by their teachers. Confirmatory factor analysis results showed that writing quality in English and Spanish in narrative and opinion genres was best described as a unidimensional skill. Structural equation model results showed that English oral language, English spelling, and Spanish spelling skills, but not Spanish oral language skill, were independently related to writing quality, after controlling for gender, English learner status, Hispanic status, and enrollment in dual immersion program. The relations of working memory and attentional control to writing quality were indirect, mediated by oral language and transcription skills. These results are discussed in light of theory and in the context of emergent bilingual children in primary grades
Semantic radical knowledge and word recognition in Chinese for Chinese as foreign language learners
In the present study, we examined the relation of knowledge of semantic radicals to studentsâ language proficiency and word reading for adult Chinese-as-a-foreign language students. Ninety-seven college students rated their proficiency in speaking, listening, reading, and writing in Chinese, and were administered measures of receptive and productive knowledge of semantic radical position and function. A latent variable for language proficiency was constructed based on the number of semesters in Chinese courses, and studentsâ self-rating in Chinese. Two language proficiency groups were reliably formed. Students with higher language proficiency had significantly better performances on all the measures of knowledge of semantic radicals and word recognition. Furthermore, the receptive and productive knowledge of semantic radical position and productive knowledge of semantic radical function were positively related to word reading after controlling for proficiency level. Productive knowledge of semantic radical function was uniquely and positively related to word reading after accounting for proficiency level and other measures of semantic radical knowledge
A creep cavity growth model for creep-fatigue life prediction of a unidirectional W/Cu composite
A microstructural model was developed to predict creep-fatigue life in a (0)(sub 4), 9 volume percent tungsten fiber-reinforced copper matrix composite at the temperature of 833 K. The mechanism of failure of the composite is assumed to be governed by the growth of quasi-equilibrium cavities in the copper matrix of the composite, based on the microscopically observed failure mechanisms. The methodology uses a cavity growth model developed for prediction of creep fracture. Instantaneous values of strain rate and stress in the copper matrix during fatigue cycles were calculated and incorporated in the model to predict cyclic life. The stress in the copper matrix was determined by use of a simple two-bar model for the fiber and matrix during cyclic loading. The model successfully predicted the composite creep-fatigue life under tension-tension cyclic loading through the use of this instantaneous matrix stress level. Inclusion of additional mechanisms such as cavity nucleation, grain boundary sliding, and the effect of fibers on matrix-stress level would result in more generalized predictions of creep-fatigue life

Do Spelling and Vocabulary Improve Classification Accuracy of Children's Reading Difficulties Over and Above Word Reading?
It is widely recognized that individuals with dyslexia have difficulties with word reading and spelling, and individuals with reading comprehension difficulties have low vocabulary knowledge. However, little is known about the extent to which spelling and vocabulary are informative of reading difficulties. In the present study, we investigated whether information on students' spelling and vocabulary in kindergarten increases the precision of identifying students with reading difficulties, using longitudinal data from kindergarten to Grade 2. The sample was composed of 247 kindergartners (55% boys; 56% White children, 35% African American children, and 5% mixed-race children; 72% from low SES) who were followed to Grade 2. Spelling improved the accuracy of identifying students who experienced word reading difficulties in kindergarten and Grade 1. In contrast, vocabulary did not improve the accuracy of identifying students with reading difficulties over and above word reading and spelling. These results indicate the importance and utility of including spelling, in addition to word reading, as an integral part of accurately identifying children with reading difficulties as early as kindergarten. In addition, although vocabulary did not contribute additional predictive power, it is likely to exert its influence at a later phase of reading development
Reducing The Risk Of Floods In Urban Areas With Combined Inland-River System
With the change of the water environment in accordance with climate change, the loss of lives and properties has increased due to urban flood. Although the importance of urban floods has been highlighted quickly, the construction of advancement technology of an urban drainage system combined with inland-river water and its relevant research has not been emphasized in Korea. In addition, without operation in consideration of combined inland-river water, it is difficult to prevent urban flooding effectively. This study, therefore, develops the uncertainty quantification technology of the risk-based water level and the assessment technology of a flood-risk region through a flooding analysis of the combination of inland-river. The study is also conducted to develop forecast technology of change in the water level of an urban region through the construction of very short-term/short-term flood forecast systems. This study is expected to be able to build an urban flood forecast system which makes it possible to support decision making for systematic disaster prevention which can cope actively with climate change
Expanding the Direct and Indirect Effects Model of Writing (DIEW) : Readingâwriting relations, and dynamic relations as a function of measurement/dimensions of written composition
Within the context of the Direct and Indirect Effects Model of Writing (Kim & Park, 2019), we examined a dynamic relations hypothesis, which contends that the relations of component skills, including reading comprehension, to written composition vary as a function of dimensions of written composition. Specifically, we investigated (a) whether higher-order cognitive skills (i.e., inference, perspective taking, and monitoring) are differentially related to three dimensions of written compositionâwriting quality, writing productivity, and correctness in writing; (b) whether reading comprehension is differentially related to the three dimensions of written composition after accounting for oral language, cognition, and transcription skills, and whether reading comprehension mediates the relations of discourse oral language and lexical literacy to the three dimensions of written composition; and (c) whether total effects of oral language, cognition, transcription, and reading comprehension vary for the three dimensions of written composition. Structural equation model results from 350 English-speaking second graders showed that higher-order cognitive skills were differentially related to the three dimensions of written composition. Reading comprehension was related only to writing quality, but not to writing productivity or correctness in writing, and reading comprehension differentially mediated the relations of discourse oral language and lexical literacy to writing quality. Total effects of language, cognition, transcription, and reading comprehension varied largely for the three dimensions of written composition. These results support the dynamic relation hypothesis, role of reading in writing, and the importance of accounting for dimensions of written composition in a theoretical model of writing.

2011 International Design Exchange Project, Hidden Space Project. Volume 2, Urban rooftops
Urban Rooftops:
Our cities are now having to rethink and redevelop the use of space more creatively and ingeniously than ever before. Space is precious in any context but the extra pressure citiesâ face with the ever growing need to accommodate increasing populations mean that every open area is now a new possibility for spatial development.
One of the most recent and fascinating trends is the use of rooftops. Their appeal lies in their surprise and undiscovered disposition. Their purpose might involve a large community or an individual but because of its elevated position, each journey to that roof space provides a chance for adventure. They are an addition to older established buildings but come with a new brief and therefore a new spirit, encouraging creativity and positive thinking, using a different energy.
The master planners and the local communities need to consider a more responsible composition of ideas to our urban and earthly needs. Sustainable energy use and material choice are to be rewarded but what of the function? Is just viewing the simple horizon above the rooftops function enough? relieving us of our daily stresses and seeing the city as sleeping giant or should we be industrious, striking balances of nature, pulling it back from disaster, giving space to synergistic projects.
The students were asked to design a Rooftop structure in a densely inhabited urban neighbourhood, namely Burbage House, Curtain Road, Shoreditch London E2.
Aim:
The aim of this lofty structure or series of structures sets out to encourage, inspire a community or an individual to cultivate positive practices. The rooftop should connect and bond visually or through metaphor within its surrounding neighbourhood. The space should take account of the social and cultural diversity that resides close by.
Context:
Shoreditch is weave of close knit streets with its former industrial context provide an area for those that want to step out of the norm and the corporate, itâs place to imagine new business. Innovative creative houses have set up home using space imaginatively, sharing with like minded disciplines.
The narrowness of the streets encourages networking and enhances collective working practices. Warehouse constructions reveal their previous activity and function, reminding us of the busy people, the noise and the industry.
The buildings allow a maximum of light though to the interior, the detail in the window frames and brickwork show a sense of pride. The Interiors are simple and true the outer structure, revealing angles and curves. The space is unattractive to the Multi-national corporations, and as there is little capacity for charging large rents makes this area economically suitable for young and emerging practices to set up.
The rawness of the interior spaces, unadulterated by recent 20th century trends provide the perfect utilitarian and vacant habitat for the fresh ideas where pioneering and ground breaking professions materialize.
View:
In some respects the rawness of such a landscape, its lack of conformity compares well with an open landscape. When standing on the roof looking across London, its openness and horizontal neutrality engenders a sense of calm and invigoration. Suddenly there are possibilities and scope for living positively. Hurried life slows down and London becomes picturesque. Novalis wrote âEverything seen from a distance becomes poetry :distant mountains, distant people, distant events. Everything become romanticâ
