Rolling with the changes: a role congruity perspective on gender norms

Abstract: Role congruity theory (e.g., Eagly & Diekman, 2005) posits that a group will be positively evaluated when its characteristics are perceived to align with the requirements of the group's typical soc...

DEX1, a Novel Plant Protein, Is Required for Exine Pattern Formation during Pollen Development in Arabidopsis

Abstract: To identify factors that are required for proper pollen wall formation, we have characterized the T-DNA-tagged, dex1 mutation of Arabidopsis, which results in defective pollen wall pattern formation. This study reports the isolation and molecular characterization of DEX1 and morphological and ultrastructural analyses of dex1 plants. DEX1 encodes a novel plant protein that is predicted to be membrane associated and contains several potential calcium-binding domains. Pollen wall development in dex1 plants parallels that of wild-type plants until the early tetrad stage. In dex1 plants, primexine deposition is delayed and significantly reduced. The normal rippling of the plasma membrane and production of spacers observed in wild-type plants is also absent in the mutant. Sporopollenin is produced and randomly deposited on the plasma membrane in dex1 plants. However, it does not appear to be anchored to the microspore and forms large aggregates on the developing microspore and the locule walls. Based on the structure of DEX1 and the phenotype of dex1 plants, several potential roles for the protein are proposed.

Are misalignments of perceptions and self‐efficacy causing gender gaps in entrepreneurial intentions among our nation's teens?

Abstract: Purpose – The purpose of this paper is to examine the reasons behind the significant gender gaps observed in entrepreneurial interest among adolescents. Specifically, the authors aim to test multiple models that analyze direct and indirect relationships between work and leadership experience, presence of a parental role model, self‐efficacy, and interest by teens in becoming entrepreneurs.Design/methodology/approach – A sample of over 5,000 middle and high school students participated in the larger study from which the data were drawn. Participants completed measures of entrepreneurial self‐efficacy, entrepreneurial intentions, work and leadership experience, and parental entrepreneurial role model. The authors analyzed the data using structural equation modeling.Findings – While the study confirmed previous empirical findings regarding the antecedents of entrepreneurial self‐efficacy and entrepreneurial intentions, significant differences across gender emerged. First, while boys and girls hold jobs outsi...
