青年农民工个体教育需求特点分析

青年农民工是农民工的主力军之一,但青年农民工与第一代农民工相比出现了许多新特点,与城市居民相比又有其特殊性。青年农民工个体教育需求首先受其个体自身因素的影响,同时受特定社会历史条件影响。本文旨在分析这些影响因素的基础上,探讨青年农民工教育需求的特殊性问题。     

Stepwise approach for view synthesis

This paper presents some techniques for synthesizing novel view for a virtual viewpoint from two given views captured at different viewpoints to achieve both high quality and high efficiency. The whole process consists of three passes. The first pass recovers depth map. We formulate it as pixel labelling and propose a bisection approach to solve it. It is accomplished in log2n（n is the number of depth levels） steps,each of which involves a single graph cut computation. The second pass detects occluded pixels and reasons about their depth. It fits a foreground depth curve and a background depth curve using depth of nearby foreground and background pixels,and then distinguishes foreground and background pixels by minimizing a global energy,which involves only one graph cut computation. The third pass finds for each pixel in the novel view the corresponding pixels in the input views and computes its color. The whole process involves only a small number of graph cut computations,therefore it is efficient. And,visual artifacts in the synthesized view can be removed successfully by correcting depth of the occluded pixels. Experimental results demonstrate that both high quality and high efficiency are achieved by the proposed techniques.

Writing plan quality: Relevance to writing scores

If writing matters, how can we improve it? This study investigated the nature of writing plan quality and its relationship to the ensuing writing scores. Data were drawn from the 1998 Provincial Learning Assessment Programme (PLAP) in Writing, which was administered to pupils in Grades 4, 7, and 10 across British Columbia, Canada. Common features of writing quality were qualitatively identified in a sample of writing plans across the three grade levels. An analytic scoring scheme based on (i) identified features of writing quality in writing plans, (ii) evaluative terms commonly used as criteria to measure writing performance in both large-scale and classroom assessments, and (iii) theory and research in writing, was developed and used to assess a sample of 1,797 writing plans. Correlation and regression analyses were used to determine relationships between quality of writing plans and writing scores. Evidence of features of writing quality in writing plans was associated with higher writing scores. Identification of features of writing plan quality provides valuable instructional information to promote student writing.
