The 1936 Olympic Games in Berlin: The Response of America's Black Press

Abstract

Eighty-seven female masters swimmers ranging in age from 20 to 69 were selected for a detailed study of their body composition and physiological responses at rest and during exercise. These women were then placed into two subsets, a highly trained group and a not highly trained group, on the basis of the frequency, duration, and intensity of swimming workouts. Significant differences were detected when comparing the highly trained and not highly trained subjects on measures of weight, body density, percent fat and lean body weight (p<.05). Significant differences which favored the highly trained group were also seen when comparing these same two groups for [Vdot]_E max, [Vdot]O₂ max (1/min), [Vdot]O₂ max (ml·kg^–1·min^–1), [Vdot]O₂ max (ml·kg·LBW^–1·min^–1), O₂ pulse (ml·kg^–1·beat^–1), and O₂ pulse (ml·kg·LBW^–1). Both the highly trained and not highly trained swimmers were considerably lower in percent fat than previously reported data for normal untrained women of similar ages. In both groups, however, percent fat across age levels within each training group showed significant increases at approximately 40 years of age (p<.05). In the highly trained swimmers, [Vdot]O₂ max (ml·kg^–1·min^–1) decreased at a mean rate of about 7% per decade, while in the not highly trained swimmers the decline was approximately 8% per decade. It appears that the rate of decline in [Vdot]O₂ max in women with aging may be independent of training status.     

黑人种族运动能力之谜试解

人类大致可分为黄种人、白种人、黑种人三大人种。人类拥有同样的祖先,为什么黑种人却比其他人种有更强的运动能力。本文从人种的生理结构特征以及人类文明对运动能力的影响进行解谜。     

论黑色词

黑色是人类社会最先出现的颜色词之一。中国古代表示黑色的词非常丰富。部分反映了我们先人的思维特点和社会生活情况。古人赋予颜色词丰富的含义。黑色也不例外。     

A snapchat story: how black girls develop strategies for critical resistance in school

ABSTRACT

Drawing from Black, feminist epistemologies as well as theories of critical consciousness, and adolescent digital literacies, this paper analyzes the narratives of 7 Black, female high school students who experience oppressive practices, including racial microaggressions, silencing, harsh discipline, and marginalization within a predominately White school environment. At this juncture in which race, politics, and activism intersect with school, media, and identity, this study discusses how Black, female students resist oppression and use digital and social media as well as other available tools to speak out against injustice and heighten the racial awareness of their school community. This qualitative case study uses individual and focus group interviews to examine the ways in which Black female students develop critical resistance strategies, working individually and collectively within existing structures to fight for their humanity and liberation.     

黑人女性主义在小说《他们的眼睛望着上帝》和《紫色》中的解读

佐拉.尼尔.赫斯顿是"哈莱姆文艺复兴"时期升起的一颗明星。当代美国著名黑人女作家艾丽斯.沃克赞誉赫斯顿为"南方天才"和她的"文学之母"。赫斯顿的代表作《他们的眼睛望着上帝》和沃克的著名小说《紫色》被誉为黑人女性主义的杰作。本文从女性主义的角度对这两部小说进行阐述,通过女性意识的觉醒和回归分析了黑人女性的独立过程。     

不同四棱豆品种豆荚比较形态学研究

以四棱豆豆荚长、宽、高、豆夹宽高比、豆粒百粒重、每个豆荚豆粒数及豆荚特异性形状等指标为依据,对不同的四棱豆品种进行形态学研究,比较不同品种之间的亲缘关系.研究方法操作性强,结果可靠,对今后四棱豆的品种选育有重要的指导意义.     

两种诱变剂对蚕豆根尖细胞遗传毒理学研究

以蚕豆根尖为材料，用微核实验和染色体畸变试验方法，研究不同浓度的8-羟基喹啉与对苯二酚对蚕豆根尖细胞的有丝分裂指数、微核率和染色体畸变率的影响．结果表明：不同浓度的8-羟基喹啉与对苯二酚使蚕豆根尖细胞有丝分裂指数明显增加，诱发较高频率的微核，在一定浓度范围内，其微核率随处理浓度的升高而升高，但随着诱变剂浓度的升高而呈下降趋势．两种诱变剂还能诱导染色体产生多种类型的畸变，染色体畸变率随着处理浓度的增加而升高，随着浓度的进一步增加却呈现下降趋势，但均明显高于对照组．     

在苦难中觉醒--浅析艾丽斯·沃克的《紫颜色》

美国当代黑人女作家艾丽斯·沃克的作品《紫颜色》 ,通过描述主人公西丽走向觉醒的历程 ,揭露了遭受种族歧视及夫权专制双重压迫的黑人妇女的苦难生活 ,并探讨了妇女尤其是黑人妇女争取独立自主生活的途径 ,因而成为美国黑人妇女文学的传世之作     

镉对绿豆和蚕豆种子萌发及幼苗生长的影响

采用水培方法,研究了不同浓度的Cd2 处理液对绿豆及蚕豆种子萌发、幼苗及根生长状况的影响.结果表明,镉处理对绿豆和蚕豆种子萌发率具有一个低浓度下的刺激效应和高浓度下的抑制效应.绿豆和蚕豆种子的发芽势均随着Cd2 处理浓度的提高而降低,并且绿豆的降低速度要大于蚕豆.低浓度的Cd2 处理不影响发芽指数,高低浓度的Cd2 处理抑制发芽指数.低浓度时,绿豆的活力指数比对照高,蚕豆的活力指数比对照低,随着处理浓度的提高,发芽指数和活力指数均下降.在处理初期,低浓度刺激幼苗的生长,随着生长时间的延长,低浓度的刺激效应逐渐消失,随浓度的提高,抑制效应逐渐增强.在处理初期,镉对根长的影响就表现为抑制效应,并且Cd2 对幼苗根长的影响比苗长的影响显著得多.     

纳西族黑白色彩崇拜

纳西族的色彩崇拜主要包括黑色崇拜、白色崇拜。其中黑色崇拜在特定历史条件的制约下 ,在早期处于纳西文化的主体地位 ,是纳西文化胚胎———祭天影响的产物 ,纳西族的自称也源于此。白色崇拜是唐宋后期才出现的 ,是受到白族、藏族白色崇拜影响的产物。纳西族的色彩崇拜既是自身民族文化发展、传承的结果 ,也是与周边民族文化融合的特殊产物。
