Abstract

Primary open-angle glaucoma (POAG), is a heritable common cause of blindness world-wide. To identify risk loci, we conduct a large multi-ethnic meta-analysis of genome-wide association studies on a total of 34,179 cases and 349,321 controls, identifying 44 previously unreported risk loci and confirming 83 loci that were previously known. The majority of loci have broadly consistent effects across European, Asian and African ancestries. Cross-ancestry data improve fine-mapping of causal variants for several loci. Integration of multiple lines of genetic evidence support the functional relevance of the identified POAG risk loci and highlight potential contributions of several genes to POAG pathogenesis, including SVEP1, RERE, VCAM1, ZNF638, CLIC5, SLC2A12, YAP1, MXRA5, and SMAD6. Several drug compounds targeting POAG risk genes may be potential glaucoma therapeutic candidates.

Abstract

Exfoliation syndrome (XFS) is the most common known risk factor for secondary glaucoma and a major cause of blindness worldwide. Variants in two genes, LOXL1 and CACNA1A, have previously been associated with XFS. To further elucidate the genetic basis of XFS, we collected a global sample of XFS cases to refine the association at LOXL1, which previously showed inconsistent results across populations, and to identify new variants associated with XFS. We identified a rare protective allele at LOXL1 (p.Phe407, odds ratio (OR) = 25, P = 2.9 × 10-14) through deep resequencing of XFS cases and controls from nine countries. A genome-wide association study (GWAS) of XFS cases and controls from 24 countries followed by replication in 18 countries identified seven genome-wide significant loci (P < 5 × 10-8). We identified association signals at 13q12 (POMP), 11q23.3 (TMEM136), 6p21 (AGPAT1), 3p24 (RBMS3) and 5q23 (near SEMA6A). These findings provide biological insights into the pathology of XFS and highlight a potential role for naturally occurring rare LOXL1 variants in disease biology.

7. Effect of Teacher Involvement in Implementation of an Innovation.

Author

Williams, Susan E.

Abstract

This study investigated the effect of teacher involvement in the development of calculator mathematics curriculum on the implementation of calculators in the classroom. Forty-five middle school mathematics teachers served as subjects. Findings revealed that teachers involved in curriculum development were observed significantly more often than those not involved in curriculum development to: explain the relationship between calculator and paper-and-pencil algorithm, stress the use of the calculator as a "time-saver," stress use of the calculator as a problem-solving tool, and initiate use of calculators in the classroom. Neither teacher attitude nor teacher involvement affected the overall quantity of student calculator use. In classrooms of teachers who were involved in curriculum development, students were observed more often than students in classes of other teachers to use calculators for exploration and induction activities, solving routine word problems, and self-checking and verifying answers. Findings indicate that classroom calculator implementation differences are not primarily the result of teacher attitude toward calculators. (Contains 17 references.) (JDD)

8. Expert/Novice Difference in Teaching with Technology.

Author

Mitchell, Janice and Williams, Susan E.

Abstract

Differences in actual classroom behaviors in teaching with technology between novice and expert teachers were studied for six middle-school mathematics teachers from a large urban/suburban school district in a major metropolitan area. Teachers received inservice training in the use of calculators, and their students were issued calculators for the school year. Teachers were categorized as experts or novices based on their educational background and observations by a superior. Observations and interviews made the differences between experts and novices apparent. Experts were more than twice as likely as were novices to focus on content and process, to determine the difficulty of the task, restructure the task as necessary, redirect student thinking, and check individual work. Experts praised student behavior more and corrected student performance twice as much, while novices were more apt to correct student behavior and were more often seen at their own desks. Novice teachers initiated use of calculators less often than did experts and were less likely to use them in class and less likely to emphasize the importance of estimation in determining the reasonableness of a calculator answer. Implications for other areas of educational technology are discussed. Three tables present study data. (Contains 11 references.) (SLD)
