Soccer is a sport not commonly associated with the Dominican Republic given the positioning of baseball as the national game. Yet, for some migrant groups in the country, such as those from Haiti, soccer plays an important part in their lives. Haitians have used soccer as a way to unite their communities and establish a sense of place. This paper assesses how these Haitian migrants use the game as a means of creating a community and developing a common focal point. Through participant observations and semi-structured interviews, this work may help us construct new understandings of the ways in which migrants use sport to assimilate to new surroundings and retain links to home. 相似文献

Median based smoothing algorithms have received considerable attention in the last few years. Their properties make them sometimes superior to linear smoothers. In this paper we develop an expression for the bivariate distribution of a median- smoothed Markov chain and we illustrate one application of it by comparing the power spectra of the input and the output of a median smoother when the input is binary valued. 相似文献

The present study examined the role of verbal working memory (memory span and tongue-twister), two-character Chinese pseudoword reading (two tasks), rapid automatized naming (RAN) (letters and numbers), and phonological segmentation (deletion of rimes and onsets) in inferential text comprehension in Chinese in 31 less competent comprehenders compared with 37 reading comprehension control students and 23 chronological age controls. It was hypothesized that the target students would perform poorly on these cognitive and linguistic tasks as compared with their controls. Furthermore, verbal working memory and pseudoword reading would explain a considerable amount of individual variation in Chinese text comprehension. RAN would have a nonsignificant role in text comprehension. Structural equation analyses and hierarchical multiple regression analyses generally upheld these hypotheses. Our findings support current literature of the role of verbal working memory in reading comprehension found in English. The results, however, suggest differential role of the constructs and the tasks in reading comprehension and provide some answers for comprehension impairment in Chinese students. 相似文献

In this paper the problem of memoryless discrete time detection of a constant signal in additive φ-mixing noise is considered. The fidelity criterion is taken to be the asymptotic relative efficiency. The optimal detector nonlinearity is approximated by a polynomial, and the statistical knowledge required for the design of the detector is the family of joint moments of the noise, resulting in a very simple design procedure for the detector. It is shown that the performance of this detector can be made arbitrarily close to that of the optimal memoryless detector for a large class of noises. 相似文献

Studying parental involvement and university access and choice: An ‘interacting multiple capitals’ model 下载免费PDF全文
Capital‐embedded parental involvement in education is essential in enhancing university enrolment and maximising the educational potentials for equality and excellence. Previous studies in this field have mainly utilised Perna's ( 2000 , 2006 ) model, which defines parental involvement as social capital and identifies the additive influences of different types of capital (including social, economic and cultural capital) on university access and choice. Yet, little research to date theorises and disaggregates the interplay among various types of capital as well as the multiplicative capital effects on enrolment. This study addressed this gap. We proposed an ‘interacting multiple capitals’ (IMC) model and hypothesised that parental social capital could moderate the effects of cultural and economic capital on entry to university. To validate the model, a pilot survey was administered to 216 university students of Korean ethnicity in China and investigated the models of involvement adopted by Korean parents in the context of the increasing labour mobility of the Korean adult population. Moderated multiple regression analysis was employed and the results confirmed the hypothesis that capital effects upon university access and choice were multiplicative in nature, with social capital moderating the cultural capital influence on students’ educational aspirations. The study findings show that the interaction of various types of capital variables is sufficiently statistically significant to warrant future research and policy and practical discussion of how to promote parental involvement in university preparation and planning. 相似文献

According to the Lexical Restructuring Model (Metsala & Walley, 1998), children move from holistic representations of words, to syllabic representations, and finally to phonemic representations through a restructuring process driven by their developing lexical base. In contrast, the psycholinguistic grain size theory put forth by Ziegler and Goswami (2005) suggests that the awareness of individual phonemes is not possible without direct literacy instruction. The purpose of this study was to examine whether semantic knowledge and/or knowledge of grapheme/phoneme correspondences influenced the acquisition of word-blending skills by a sample of children with a reading disability. Participants were 211 second-grade and third-grade students from public elementary schools who were assigned to a reading intervention. Hierarchical Linear Modeling techniques were used to model individual growth curves of word-blending skills. Overall, findings support the psycholinguistic grain size theory of reading and suggest that instruction in the relationship between orthographic patterns and their corresponding sounds is necessary for the development of phonological awareness. 相似文献
