印象派绘画的色彩魅力刍议

以印象派绘画的色彩表现为主线，从印象派绘画的基本概况出发，通过物理学对光与色的分析，引中出光对人的视觉感知的重大影响。以印象派代表画家的绘画风格为例，分析了光与色的发展历程，并系统总结了印象派画家创造性的色彩表现样式。重新解读了印象派绘画的色彩魅力。     

材质的光色影像:媒材与印象派绘画

绘画史是由对媒介的兴趣所支撑着的历史,媒介贯穿着整个绘画历程.艺术史上的每一次变革都伴随着媒材自身的变革,在某些情境下媒材的变革甚至成为了各种艺术潮流、风格演变的先声.印象派正是媒材通过画面的传达和表现,它将人们对古典艺术的形体与线条的崇尚引向对色彩的关注,其作品体现着对色彩的视觉革命所做的贡献与价值.通过物质和精神媒材的演变,印象派绘画映像了社会和时代.     

The Practical Logic of the Comintern from the Perspective of World Revolution

As a “World Communist Party” organization, the Comintern was profoundly influential in the history of the international Communist movement. The Comintern was established on the theoretical foundation of the theory of world revolution, but it underestimated how long that would take. Despite being the unified organizational vehicle of the “World Communist Party,” the Comintern underestimated the complexity of relations between itself and each country’s Communist Party, among these national Communist parties, and between Communist and social democratic parties. A classic example was the fact that although the Comintern developed close relationships with the Communist Party of China (CPC), it underestimated the particularity of Chinese revolution.     

满洲窗：中西文化融合的岭南传统建筑装饰元素

“满洲窗”是广东民间在清朝中后期至抗日战争前以广州为中心的珠江三角洲直至岭南的一些私家园林、民居及商住类建筑中比较常见的建筑装饰花窗的俗称.与常说的岭南传统建筑装饰元素三雕（木、砖、石）两塑（灰塑、陶塑）相比,“满洲窗”和两塑更加专属岭南.“满洲窗”的形成、发展其实是从一个侧面研究广州、岭南乃至中国进入近现代以来传统建筑文化与外来文化的融合及变革的过程.     

Women's Hair Color and Survey Response Rate: A Field Experiment

Previous research found that survey response rates were influenced by physical characteristics of the interviewer. However, the effect of hair color on compliance to a survey request has never been studied. Female confederates wearing blond, brown, black, or red wigs solicited 1,200 male and female pedestrians for a survey. It was found those male passersby, but not the female, agreed more frequently to the confederates wearing blond wigs whereas they agreed less to the same confederates wearing red wigs. Greater youth and healthiness associated with blond hair in women is used to explain these results. The practical interest in face-to-face surveys is addressed.     

A Theory for Coloring Bivariate Statistical Maps

Consideration of some practical uses of statistical bivariate maps—for example, display of association between variables—leads to principles for making effective use of color to represent data values. Effective color schemes for bivariate maps are viewed as continuous transformations from color models to the unit square with appropriate restrictions involving hue, saturation, and brightness. Several schemes, including those used by the U.S. Census Bureau, are criticized on the basis of this theory.     

Trends in the History of Vocational Guidance

In this article, the relationships between vocational guidance and vocational education, employment counseling, career guidance, and career counseling are explored. Also examined are the wide‐ranging federal and state policies that have stimulated and shaped the professional history of vocational guidance, vocational policy, and contemporary terms.     

Counseling Strategies with Gay and Lesbian Youth

Counseling needs of gay and lesbian youth have not been adequately researched. Identification of these issues has only been underway for adequately researched. Identification of these issues has only been underway for approximately ten years, as service providers and researchers turned their attention to this population. Factors, which contribute to a presenting clinical picture, include stigmatization, hiding and isolation, a sense of being different, lack of family support, harassment, and violence. Each of these areas is discussed, integrating case vignettes and research findings.     

论唐代德顺时期的立储之争

唐代德宗、顺宗时期,统治阶级内部围绕着立储问题展开了激烈斗争.在顺宗即位前,主要是官僚集团与宦官的较量;顺宗上台后则演变为顺宗支持的革新派同宦官及守旧官僚的斗争.     

Final report of the Color Additive Scientific Review Panel

The Color Additives Scientific Review Panel considered whether there was information sufficient to perform a carcinogenic risk assessment on the colors D&C Red No. 19 (R-19), D&C Red No. 37 (R-37), D&C Orange No. 17 (O-17), D&C Red No. 9 (R-9), D&C Red No. 8 (R-8) and FD&C Red No. 3 (R-3) and to evaluate the assessments sent to FDA as part of the petitions for use of the colors for drug and external uses by the Cosmetic, Toiletry and Fragrance Association (CTFA). There is a lack of human data concerning the colors for making a human health assessment, so the assessments are based upon the extrapolation of animal data. The risk assessments are determined for exposure to single chemicals. Excluded from consideration are possible effects from exposure to multiple chemicals, such as co-carcinogenesis, promotion, synergism, antagonism, etc. In the light of recent efforts in establishing a consensus in risk assessment, the Panel has determined that the CTFA assessments for R-10, O-17, and R-9 are consistent with present acceptable usages, although it questions some of the assumptions used in the assessments. The Panel identified a number of general assumptions made, and discusses their validity, their impact on total uncertainty, and the potential options to address the gaps in understanding that necessitate the assumption. The Panel also derived revised risk estimates using more "reasonable" assumptions than "worst-case" situations, for 90th percentile and average exposure. For those assumptions that are easily quantifiable, the Panel's estimates are less than an order of magnitude lower than the CTFA risk estimates, indicating that the underestimates and overestimates of the CTFA risk estimates tend to balance each other. The impact of most of the assumptions is not quantifiable. The assessment for R-3 is complicated by the fact that there is no good skin penetrance study for this color. It was assumed that the penetrance is similar to that of another water-soluble xanthene color, R-19. It is expected that the absorption of the color is not likely to exceed that of the smaller molecule, R-19. Therefore, the risk estimates are similar to the CTFA estimates, but with different reasoning. The estimates for R-8 and R-37 are different from the others in that there is a lack of any exposure or toxicological information on these colors.(ABSTRACT TRUNCATED AT 400 WORDS)
