The Diverse Gifts of Dr. Leslie R. Williams

Preparing students in the early childhood field to work with children both with and without disabilities and to collaborate with different professionals is an important endeavor for colleges and universities. The purpose of this paper is to articulate a unique model of program collaboration between early childhood special education and early childhood regular education that demonstrates a cohesive preservice teacher education program across two departments within one university. This unique 10-year history of interdisciplinary collaboration and team teaching provides insights into many of the benefits and challenges of this type of program. This paper presents an historical overview of the development of this collaborative program and describes the logistics of operating an interdisciplinary program at the administrative level. Information collected from faculty and students illustrates the benefits and challenges of team teaching. Finally, strategies for developing a successful program are discussed.     

一瓶子回忆芳菲

你试过用鼻子来记事情吗?也许热狗的香味会让你发一场仿如置身棒球比赛的白日梦。又或者,烧棉花糖的味道使你忆起一个篝火之夜。科学家们现在知道嗅觉能触动强烈的回忆。要是能把这些回忆存在小瓶子里不是很棒吗?     

社鼠、雷琼社鼠和针毛鼠染色体分类的研究

社鼠、雷琼社鼠和针毛鼠都是山地栖息种类，它们染色体的2n数目和形态明显有别于同属的其他各种．体现出它们之间的亲缘关系较近，它们间的核型演化是通过罗伯逊易位和缺失途径，社鼠、雷琼社鼠和针毛鼠有着不同于属中其他种类的生态位，把它们另作一属会恰当些；社鼠和雷琼社鼠的地理分布有所不同．但染色体组型并不差异．认为它们间可能仅是毛色变异，而不存在两个亚种之分．
