Narrowing the gap.

Design and Validation of a Conceptual Model for Narrowing the Gap between Intended, Implemented, and Attained Curricula in the Public Education System in Iran

Abstract: The present research aimed at developing and validating a conceptual model for narrowing the gap between intended, implemented, and attained curricula in the public education system in Iran. Two fundamental questions guided this investigation: what model can be developed to reduce the gap between the three mentioned curricula? To what extent does the proposed model gain the approval? ...

Oxygen vacancy induced band gap narrowing of ZnO nanostructures by an electrochemically active biofilm.

Band gap narrowing is important and advantageous for potential visible light photocatalytic applications involving metal oxide nanostructures. This paper reports a simple biogenic approach for the promotion of oxygen vacancies in pure zinc oxide (p-ZnO) nanostructures using an electrochemically active biofilm (EAB), which is different from traditional techniques for narrowing the band gap of na...

Structural change and the narrowing gender gap in wages: theory and evidence from Hong Kong

This paper offers a theoretical and empirical analysis on the sources of the narrowing gender gap in wages. Based on some existing literature, the model posits that the narrowing gender gap may be related to women’s changing comparative advantage and the gender gap is smaller in occupations in which physical labor is less intensively used. The model implies that when an economy transforms from ...

Study of Dopant-Dependent Band Gap Narrowing in Compound Semiconductor Devices

Band gap narrowing is one of the crucial heavy-doping effects to be considered for bipolar devices. In case of HBTs, where discontinuities in the energy levels appear, the correct modeling of the energy barriers has basic importance for studying the device performance. Using the physically-based approach from [1], we present a new band gap narrowing model which considers the semiconductor mater...

Bridging the semantic gap for software effort estimation by hierarchical feature selection techniques

Software project management is one of the significant activates in the software development process. Software Development Effort Estimation (SDEE) is a challenging task in the software project management. SDEE is an old activity in computer industry from 1940s and has been reviewed several times. A SDEE model is appropriate if it provides the accuracy and confidence simultaneously before softwa...
