This study investigated the long-term effects of social disadvantage on academic achievement and on subsequent attainments in adulthood. The study drew on data collected for over 30,000 individuals born 12 years apart, following their development from birth to adulthood. The pathways that link social disadvantage to individual development across the life course were analyzed in a developmental-contextual systems model. The results showed that the influence of risk factors associated with socioeconomic disadvantage depended on the developmental stage of the individual, the experience of long-term or continuous disadvantage, and the overall sociohistorical context. Early risk had a moderate influence on the formation of individual competences. The greatest risk was associated with persisting and accumulating experiences of socioeconomic disadvantage throughout childhood and adolescence. Material conditions improved for the later-born cohort, yet pervasive social inequalities existed that affected outcomes during childhood and were consequently reflected in adult attainment. 相似文献

The research reported in this paper attempted to find whether the so called poor spellers who are good readers are indeed good readers or if this impression is misleading. Three college students who appeared to be poor spellers but good readers were tested using a variety of techniques. It was found that the three subjects were indeed inefficient readers who committed numerous errors in reading function words, low frequency and unfamiliar words, and pronounceable nonwords. Not being proficient in the phonological conversion of print, these subjects depend excessively on an orthographic sight reading strategy which hinders accurate reading. There appears to be a trade off between speed and comprehension in reading and by slowing down considerably, the poor spellers but good readers attain an acceptable level of comprehension. It was concluded that reading aloud and spelling involve phonological mediation and, therefore, are not completely dissociable. 相似文献

Effect of feeding ripe and unripe papaya fruit pulps were investigated on blood lipid profile of normal male adult albino rabbits by giving them pulps separately at the dose of 15 and 30g per day along with standard diet over a period of six weeks. As compared to controls both fruit pulps resulted in highly significant (p<0.001) and consistent lowering of serum cholesterol, low density lipoprotein cholesterol and triglycerides and elevation in phospholipids and high density lipoprotein cholesterol levels at 1,3 and 6 weeks of fruit pulp feeding indicating a dose dependent effect. Observations clearly support medicinal value ofC. Papaya in the management of atherosclerosis, fatty liver, ischaemic changes and consequential myocardial infarction. 相似文献

Dietary fiber alone or coupled with other factors affects the utilization of nutrients. In the present investigation, response of 4 men consuming diets at 3 levels of energy and neutral detergent fiber (NDF) was studied. Pooled ANOVA for 3 experiments with 4 subjects showed significant differences between the experiments within the subject (P< .01) for digestibility of fat, carbohydrate, nitrogen and NDF. Results indicate that habitual NDF intakes of about 40 grams per day have digestibility of 49% and that amount and source of fiber modify the fat digestibility. 相似文献

Not all reading disabilities are alike 总被引：1，自引：0，他引：1
In this article, reading disability is defined broadly to refer to below-average achievement in reading comprehension as assessed by a standardized test. With our research we tried to answer the question of whether all children with reading disability share a common etiology of deficient phonology, or constitute heterogeneous groups. The answer to this question was sought in four studies that examined reading disabilities from the perspective of componential skills of reading. In Part 1, the results of the first study are reported. A principal-components analysis of the performance of 139 children from Grades 3, 4, and 6 on reading-related tasks yielded two factors: decoding and comprehension. However, factor analyses conducted for each grade separately indicated that orthographic skill and processing speed could possibly constitute a third component. The orthography-speed factor emerged as a factor only in the 6th grade. Part 2 of this article reports the findings of three studies that analyzed the componential skills profiles of poor readers. It was found that the poor readers constituted heterogeneous groups and that four different types of poor readers could be identified with deficiency in any one of the following skills: (a) decoding only, (b) comprehension only, (c) a combination of decoding and comprehension, and (d) a combination of orthographic processing and reading speed. It was also found that the criteria used in selecting poor readers influenced the distribution of the ratio of the four types of poor readers within any given group. 相似文献
