Comparative studies on phenotypic plasticity of two herbs, Changium smyrnioides and Anthriscus sylvestris

INTRODUCTION Changium smyrnioides Wolff, a monotypicspecies of family Umbellaceae, occurs only in anarrow zone in the middle to eastern part of theChangjiang (Yangtze) River Basin, China. As ahighly valued medicinal herb, the fleshy roots ofthis species are widely picked, and as its habitatsare being disturbed increasingly by land use, it hasbecome an endangered species (Qiu and Fu, 2001).Anthriscus sylvestris (L.) Hoffm belongs to thesame family; has similar morphology and life…

Lucid education: resisting resistance to inquiry

Within the community of inquiry literature, the absence of the notion of genuine doubt is notable in spite of its pragmatic roots in the philosophy of Charles Saunders Peirce, for whom the notion was pivotal. We argue for the need to correct this oversight due to the educational significance of genuine doubt—a theoretical and experiential understanding of which can offer insight into the interrelated concepts of wonder, fallibilism, inquiry and prejudice. In order to detail these connections, we reinvigorate the ideas of Peirce by borrowing the language and concepts of Albert Camus, at the same time demonstrating their unlikely congruence. In particular, we argue for the necessity of genuine doubt along with the need for the presence of a diversity of prejudices as a starting point for genuine inquiry.     

Racial Identity and Psychological Symptoms Among African Americans Attending a Historically Black University

Previous research found racial identity predictive of psychological distress among African American students at predominantly White colleges. This study examined these relationships among 154 African American undergraduates attending a historically Black university. Racial identity was independent of psychological distress, suggesting that African American students' racial identity predicts psychological distress only in settings in which they are the minority.     

Validity of the comprehensive receptive and expressive vocabulary test in assessment of children with speech and learning problems

The current researchers investigated construct, predictive, and differential validity for the Comprehensive Receptive and Expressive Vocabulary Test (CREVT). Participants were 243 public school students, ages 5.5 to 17.25 years. They represented four primary disabilities: Learning Disability (n = 115), Learning Disability with Speech Impairment (n = 29), Mental Retardation (n = 40), and Speech Impairment (n = 59). Adequate construct validity for the CREVT was documented, using the Wechsler Intelligence Test for Children–III as a criterion. Also, the CREVT significantly predicted the scores on the Wide Range Achievement Test–3. Lastly, the CREVT effectively differentiated between students with disabilities. These findings suggest that the CREVT may be helpful in identifying the presence of learning problems. © 2002 Wiley Periodicals, Inc. Psychol Schs 39: 613–619, 2002.
