Searching high gray scale FPD scanning matrix based on PSO

With the increase of gray scale and flat panel display (FPD) size, subspace bitwise scanning strategy can be replaced traditional scanning method to cut down frame frequency. However, the direct searching strategy (DSS) becomes unfeasible to obtain corresponding high gray scale scanning matrix. Thus, particle swarm optimization (PSO) is introduced to accelerate searching for high gray scale weights scanning matrix (WSM) with its parallelism and global optimization feature. Finally a WSM of 256 gray scales is found out successfully with Matlab, which both gray linearity and scanning efficiency are satisfied.     

中国的城市化与土地制度改革

我国宪法一方面规定城市的土地归国家所有,农村的土地归集体所有,这就意味着无论是公益性还是非公益性土地需求,都必须通过国家的征地行为来满足,必须先变成国有;另一方面《宪法》又明确表明,国家只有出于公共利益的需要,才能对农地进行征收或者征用。现行征地制度中存在着这个二律背反,应进一步创新和完善城市国有土地制度改革和农村集体土地制度改革的基本思路,尤其要重视研究解决城乡建设用地增减挂钩中土地增值的分配、城市化与土地适度规模经营以及农民增收的关系、城乡宅基地同权同价以及粮食安全责任分摊等问题。     

江苏省幼儿园教师规模现状及其“十二五”需求预测

为实现《江苏省中长期教育改革与发展规划纲要(2010-2020年)》提出的全省学前教育“十二五”发展目标,需要科学地预测和估算江苏省“十二五”期间新增幼儿数及幼儿教师数.本研究结果显示,按照35/2的师生比,江苏省现有幼儿教师数量不仅总量不足,而且存在显著的地区分布差异,主要是经济欠发达地区幼儿教师缺口较大.未来5年,根据江苏省人口出生率与在园幼儿数推算,江苏省幼儿教师缺口将达到3万人左右,其中专科及以上学历者缺2.7万名,本科及以上学历者缺1.05万人.为弥补幼儿教师数量与质量的不足,各级政府应继续加大财政投入,并逐步主要投向幼儿教师的培养、培训及待遇保障;教育行政部门应合理规划幼师生培养规模,多渠道增加幼儿教师培养数量,同时应加强现有幼儿教师学历培训.     

人体大肠癌雌孕激素受体的研究

我们利用冰冻切片和酶联(E_2—HRP,Pg—HRP)免疫组织化学方法、检测了82例大肠癌组织中的雌、孕激素受体(ER、PR),结果表明:ER阳性率为54.87％、PR阳性率为45.12％。本实验提示在大肠癌45—54％的病例属激素依赖型。文中对ER、PR的结构和作用机理进行了阐述。

Global Social Responsibility: Developing a Scale for Senior High School Students in Japan

This research was conducted with the aim of clarifying a concept of “global social responsibility.” A total sample of 395 senior high school students in Japan responded to a pool of items mostly adapted from a scale developed by Starrett (1996) and provided additional data concerning their social experiences. The data were used in the development of a Japanese version of the Global Social Responsibility (GSR) scale. It was found that “global altruism,” “active involvement with society,” and “understanding of interdependence” constituted a construct of global social responsibility. It was also found that females, those who discussed social problems with their family, those who revealed a high awareness of responsibility and those who had multiple experiences of volunteer activities for community service showed high GSR scores. The scale provides both an awareness of the concept and a measure for determining levels of global social responsibility. Counseling professionals are encouraged to consider their roles from a global and social perspective, with the notion of responsibility being seen as central to the concepts of freedom and personal development.
