战争与20世纪外国文学--兼论茨威格小说对战争的描写

20世纪已经成为历史,当我们回眸20世纪外国文学时,必须正视“战争与20世纪外国文学”这个无法回避的话题。战争使人的处境变得越来越难以理喻,人们在精神上普遍感到迷惘、痛苦、悲观。人的心理变得更加复杂。20世纪西方社会的种种困惑人心的问题以完全不同于19世纪传统作家的方式进入了文学。茨威格像20世纪其他许多作家一样,在其作品中很少像传统文学那样直接再现战争场面．主要是表现战争对人心理的冲击和影响。     

高中地理核心素养与课堂深度融合策略研究

高中地理核心素养的培养需要融入课堂教学中,教师要把提高学生的学科素养作为地理教学的重要目标。教师要围绕地理核心素养培养,从人地协调观、地图解读能力、空间思维能力、地理实践能力、多媒体教学、地理问题生活化等方面促进学生地理思维能力的提高。     

急性铅中毒对小鼠睾丸病理损伤研究

为了研究急性铅中毒对小鼠睾丸病理变化的影响,通过对小鼠饲喂含有醋酸铅的去离子水建立铅负荷小鼠模型.处理10 d后取材,分析体质量、睾丸指数和睾丸病理剖检变化.结果显示：与对照组相比,铅中毒组小鼠体质量无明显变化,睾丸指数降低,且差异显著（P＜0.05）;小鼠睾丸中支持细胞、生精细胞和间质细胞数量减少.铅对小鼠睾丸具有显著损害作用,从而影响小鼠的生殖健康.     

Multi-face detection based on downsampling and modified subtractive clustering for color images

INTRODUCTION Face detection has been widely used in fields such as security, multimedia retrieval, human com-puter interaction, etc. Therefore it becomes one of the most active research areas in computer science. Re-cently, approaches to face detection include neural network (Rowley et al., 1998), boosting (Viola, 2001; Viola and Jones, 2004), template matching (Kim et al.,2000) and skin color (Cai and Goshtasby, 1999; Wang and Yuan, 2001; Soriano et al., 2003), etc. The methods of n…

Limitations to teaching children 2 + 2 = 4: typical arithmetic problems can hinder learning of mathematical equivalence

Do typical arithmetic problems hinder learning of mathematical equivalence? Second and third graders (7–9 years old; N= 80) received lessons on mathematical equivalence either with or without typical arithmetic problems (e.g., 15 + 13 = 28 vs. 28 = 28, respectively). Children then solved math equivalence problems (e.g., 3 + 9 + 5 = 6 + __), switched lesson conditions, and solved math equivalence problems again. Correct solutions were less common following instruction with typical arithmetic problems. In a supplemental experiment, fifth graders (10–11 years old; N= 19) gave fewer correct solutions after a brief intervention on mathematical equivalence that included typical arithmetic problems. Results suggest that learning is hindered when lessons activate inappropriate existing knowledge.

Adolescent academic achievement: A model of social support and grit

Grit has been defined as passionate perseverance toward long-term challenging goals and it is associated with various positive outcomes for youth, including academic achievement. However, less is known about these associations for the two facets of grit (i.e., perseverance of effort, consistency of interest) and few studies have examined the link between grit and perceived social support. The present study examined the group-level demographic differences (i.e., gender, grade, socioeconomic status, and special education status) of grit in a high school sample (N = 1,077). In addition, direct associations between grit and perceived social support from multiple sources (i.e., teacher, classmate, parent) were examined, as well as a potential enhancing effect of social support as a moderator of the relation between grit and academic achievement. Results indicated positive associations among grit and its facets with social support from parents and classmates. Furthermore, the positive relation between grit and achievement was stronger for students reporting high social support from teachers, but not other sources (i.e., classmates, parents). Practical and theoretical implications for promoting student success are discussed.     

Effects of a Teacher‐Designed and Teacher‐Led Numerical Board Game Intervention: A Randomized Controlled Study with 4‐ to 6‐Year‐Olds

The purpose of the current pilot study was to examine the effects of a teacher‐designed and teacher‐led numerical board game intervention. Fifty‐four 4‐ to 6‐year‐olds were randomly assigned to either the number board game intervention or an active control group. Relative to the control group, children who received the number game intervention demonstrated significant improvements on a numeral identification task. This finding is significant in so far as numeral identification skills play a critical role in more advanced numerical and mathematical reasoning. There was no evidence of training‐related improvements on any of the other tasks. In addition to the intervention effects, the present study provides an example of a successful teacher‐researcher collaboration, providing new insights into the making of bidirectional relations between research and practice.     

College Students Perceptions Toward Carrying Concealed Weapons on College Campuses

This study uses a survey of undergraduate college students at two schools in the eastern United States to investigate their attitudes toward carrying concealed weapons on campus. We found that politically conservative white men who own guns are more likely to be in favor of qualified students and faculty carrying concealed weapons on campus than politically liberal non-whites and women who do not own guns. Neither academic major nor age had a significant effect on any of our dependent variables.
