Morphological and molecular screening of French bean (Phaseolus vulgaris L.) germplasm using SCAR markers for Colletotrichum lindemuthianum (Sacc. and Magn.) Scrib. causing anthracnose resistance

Abstract: This study was carried out to screen Phaseolus vulgaris L. germplasm accessions for anthracnose resistance genes to the fungus Colletotrichum lindemuthianum. (Sacc. and Magn.) Scrib. This fungus is made up of many pathogenic races which poses a challenge in developing resistant plant varieties; however, screening for and selection of resistant plant sources plays an important role in developing resistant plant lines. This screening work involved examining 69 accessions consisting of two resistant lines (D-line, L-line) and two susceptible varieties (Kanchana and Jwala). Fourteen SCAR primers specific to anthracnose disease resistance in the French bean were used. Of these 14 SCAR primers, 5 of them, SAS13, SF10, SC08, SZ04 and SBB14, produced amplification with good monomorphic bands.

Pattern of Morphological Variability in Unrepaired Unilateral Clefts With and Without Cleft Palate May Suggest Intrinsic Growth Deficiency.

Abstract: In individuals with cleft lip and palate (CLP) an iatrogenic effect of operations on subsequent maxillary growth is well-known. Much less is known about the association between occurrence of CLP and intrinsic growth deficiency of the maxillofacial complex. The aim of this study was to compare morphological variability in subjects with unilateral cleft lip and alveolus/palate and unaffected controls using geometric morphometric methods. The research hypothesis was that if subjects with unrepaired unilateral CLP have intrinsic growth deficiency, the pattern of their craniofacial growth variation may differ from that in unaffected individuals. Lateral cephalograms were available of three groups of the same ethnic background (Proto-Malayid): (a) non-syndromic unrepaired unilateral complete cleft lip, alveolus, and palate (UCLP), N = 66, mean age 24.5 years (b) non-syndromic unrepaired unilateral complete cleft lip and alveolus (UCLA), N = 177, mean age 23.7 years, and (c) NORM (N = 50), mean age 21.2 years without a cleft. Using geometric morphometrics shape variability in groups and shape differences between groups was analyzed. Principal component analysis (PCA) was used to examine shape variability, while differences between groups and sexes were evaluated with canonical variate analysis. Sexual dimorphism was evaluated with discriminant function analysis (DA). Results showed that in comparison to NORM subjects, shape variability in UCLA and UCLP is more pronounced in the antero-posterior than in vertical direction. Pairwise comparisons of the mean shape configurations (NORM vs. UCLA, NORM vs. UCLP, and UCLA vs. UCLP) revealed significant differences between cleft and non-cleft subjects. The first canonical variate (CV1, 68.2% of variance) demonstrated that differences were associated with maxillary shape and/or position and incisor inclination, while in females, the CV1 (69.2% of variance) showed a combination of differences of "maxillary shape and/or position and incisor inclination" and inclination of the cranial base. Shape variability demonstrated considerable differences in subjects with UCLA, UCLP, and NORM. Moreover, in subjects with a cleft, within-sample variability was more pronounced in the antero-posterior direction, while in non-cleft subjects, within-sample variability was more pronounced in the vertical direction. These findings may suggest that subjects with unilateral clefts have intrinsic growth impairment affecting subsequent facial development.

Discourses on Student Learning: Interviews with Outstanding Principals of Chicago Public Schools.

Abstract: This paper examines Chicago elementary school principals' views on the obstacles to student learning posed by the socioeconomic and racial/ethnic characteristics of students. The paper includes the principals' policy recommendations for overcoming these obstacles. It focuses on the discrepancies between the ideal and the reality of student failure as experienced in the principals' own schools and discusses the failure of American schools overall to educate disadvantaged students. The report is based on a qualitative study of 13 principals who received an outstanding leadership award in the Chicago public schools. School report-card data from each of the principal's schools were also used to discover the extent of change in student outcomes in each school over the past 3 years. Principals were asked to share their philosophy about educating urban students, particularly minority and low-income students; to discuss why there is an achievement gap between minority students and nonminority students; and to describe programs they have developed to boost the academic achievement of these students. All the principals held that every student can learn, and all were conscious of the many hurdles their students face when trying to learn. However, the principals were willing to search for ways to overcome these hurdles. (Contains 40 references.)

Potential Benefits of Analyzing Website Analytic Data

Abstract: This article presents an overview of the potential benefits of analyzing website analytic data. During the last several years I have gained first-hand knowledge of Internet marketing programs of a variety of companies ranging from national name brands to small businesses. In addition, I have been active in the local chapter of the American Marketing Association. During this time, it has become clear to me that many small business owners and marketing managers at various size companies lack a basic understanding of the potential benefits of analyzing website analytic data. This article introduces the basics of website analytics and the potential benefits derived from analyzing that data. The objectives of this article include:
