Introduction to “Racial Inequality and Education: Patterns and Prospects for the Future”     

Pedro A. Noguera 《The Educational forum》2017,81(2):129-135

Abstract

American society is in the midst of profound economic and demographic changes. At the same time that the racial and ethnic composition of American society is changing, disparities in income and wealth have grown wider and more pronounced than ever before. This article explores the ways in which race is implicated in the widening gaps in wealth and opportunity, and how these inequities impact educational achievement.  相似文献

Knowledge Capabilities of Local Government in the Context of Decentralisation in Ukraine     

Inna Koblianska  Viktoriia Medvid  Viacheslav Pylypenko  Olena Diachenko 《Africa Education Review》2020,17(3):1-21

Abstract

There is an increasing actualisation of the knowledge component of the institutional capacity of local self-government authorities in Ukraine within ongoing decentralisation. The issue that arises concerns the officials’ knowledge sufficiency to generate and implement new ideas on the territories’ development, and the availability of unique skills for the development of relevant programmes, projects and plans. Herein, the analysis of the real knowledge needs of officials, whose sphere of competence lies in decision-making about the territories’ ways of development as well as their practical implementation, plays an important role. The article presents the results of a study of the opinions of local self-government officials of united territorial communities (UTCs) from the Dnipropetrovsk, Sumy, Zhytomyr, Kherson and Poltava regions of Ukraine, concerning their level of knowledge on the territories’ management; their needs for additional knowledge; the most common and convenient ways of obtaining knowledge; and the most problematic areas where the new knowledge is most demanded. The obtained data and the conclusions drawn can be considered, in particular, as an informational basis for the formation of training programmes and plans, cases and tasks for specialists training in the field of public administration.  相似文献   

Beauty and Character: Values Beyond Beauty in Architecture     

Stanley Stein  Michael McMordie 《Interchange》2002,33(2):183-191

Formalist conceptions of aesthetic goals began to give way from the 17^th century on to rationalist accounts of experience. Beauty as described as essential by Renaissance thinkers was reconceived as just one possibility, with the sublime in Burke's account as another. In the early 20^th century Clive Bell again asserted a formalist position with his argument for significant form. The weakness of the formality position, and the need for a richer, more contextual account of aesthetic goals and experience is argued with reference to the idea of thick and thin concepts as applied by Bernard Williams to ethics, Wittgenstein's attention to the way in which language is used in a specific context, and Scruton's emphasis on an informed conception of the object of aesthetic attention. Beauty, in Alberti's procedural account if not in his version of the Platonic ideal, can be seen to continue to have critical value. The idea of character, however, offers a broader range of possibilities for experience and of goals for design.  相似文献   

EUTECTOID STRUCTURES IN NICKEL-ALUMINIUM BRONZES     

孙扬善 《东南大学学报》1989,(2)

This paper discusses the microstructure of nickel-aluminium bronzes con-taining(9-10)wt% Al and(0.1～5)wt% Ni,in which three eutectoids may exist.Themorphologies of α+γ_2 and α+β'_2 are similar but the latter is finer.In the α+β'_2+γ_2eutectoid structure β'_2 is mainly concentrated at the α/β boundaries,while γ_2 is distrib-uted inside prior B regions.Both K-S and N-W orientation relationships exist betweenα and β'_2(or γ_2)in alloys consisting of α+β'_2 or α+γ_2.However,if the alloy consists ofα+β'_2+γ_2 eutectoid,the lattices of β'_2 and γ_2 are parallel,both of them have the N-Worientation relationship with α.  相似文献   

How Integration Matters: An Alternative Vision for Urban Education in an Era of the Market     

Joseph B. Johnston 《Journal of School Choice》2016,10(4):516-536

ABSTRACT

The widespread assumption in the United States today is that traditional urban public schools are failing. Market-based solutions, particularly charter schools, are seen as the way to improve urban education. How then can we understand a large urban district where educational actors have furthered a locally popular alternative vision? This article analyzes the comparison of Indianapolis, IN and Louisville, KY to demonstrate how four-decades-old desegregation orders continue to matter for the perceptions of urban school districts. The analysis shows how actors in Louisville utilized more favorable perceptions to fight for a compelling alternative narrative–integration–and against charter schools.  相似文献   

《美化文学名著丛刊》的美学特征     

秦川 《大连大学学报》2007,28(4):11-15

《美化文学名著丛刊》是民国时期朱剑芒选录、上海世界书局出版的一部文言小说总集。此集收明清间文言小说名著十种,体现了五个方面的美学特征,即在情词色调上,强调“乐而不淫”、“不浓也不淡”的“中和”之美;在感觉和体验上,则讲究“有味”、“可人”的美学效果;特别是把传统道德的至善、至德作为“至美”的标准来认定和强调,更可谓深得老庄哲学和美学的三昧,是一部名副其实的美文名著。  相似文献
