    The dramatistic genre in leadership studies: Implications for research and practice

    No full text
    Since the late 1980s, leadership theorists and researchers have appreciated the significance of leaders as makers of meaning. While this understanding has stimulated a greater need to link leadership to organizational symbolism and organizational sense-making issues, the focus on these issues has resulted in not insignificant dissatisfaction with conventional approaches to the study of leadership. In response, this article proposes a complementary alternative focus for research and practice in the leadership area. It advances the use of the symbolic and relational aspects of leadership as highlighted in the three subgenres of dramatism namely: Kenneth Burke’s dramatism (life is drama), Erving Goffman’s dramaturgy (life is like drama ) and Victor Turner’s social drama (life and drama are interdependent ). There-after the article explores the key distinctions between the three sub-genres so as to identify their analytical as well as explanatory focus. Implications for leadership research and practice using the three subgenres are presented. The article closes with a discussion on the opportunities an integrated dramatistic approach might offer the general field of leadership

    Amplified fragment length polymorphism as a tool for molecular characterization of almond germplasm: genetic diversity among cultivated genotypes and related wild species of almond, and its relationships with agronomic traits

    18 pages, 6 figures, 5 tables.-- Published online: 10 March 2007Amplified fragment length polymorphism (AFLP) analysis is a rapid and efficient method for producing DNA fingerprints and molecular characterization. Our objectives were to: estimate genetic similarities (GS), marker indices, and polymorphic information contents (PICs) for AFLP markers in almond cultivars; assess the genetic diversity of almond cultivars and wild species, using GS estimated from AFLP fingerprints and molecular characterization; and facilitate the use of markers in inter-specific introgression and cultivar improvement. The genetic diversity of 45 almond cultivars from Iran, Europe, and America, were studied assaying 19 primer combinations. In addition, several agronomic traits were evaluated, including flowering and maturity times, self-incompatibility, and kernel and fruit properties. Out of the 813 polymerase chain reaction fragments that were scored, 781 (96.23%) were polymorphic. GS ranged from 0.5 to 0.96, marker indices ranged from 51.37 to 78.79, and PICs ranged from 0.56 to 0.86. Results allowed the unique molecular identification of all assayed genotypes. However, the correlation between genetic similarity clustering as based on AFLP and clustering for agronomic traits was low. Cluster analysis based on AFLP data clearly differentiated the genotypes and wild species according to their origin and pedigree, whereas, cluster analysis based on agronomic data differentiated according the pomological characterization. Our results showed the great genetic diversity of the almond cultivars and their interest for almond breeding.The authors are grateful to Shahrekord University for financial assistance.Peer reviewe
