The Strategic Consulting Experience: Providing Experiential Learning Opportunities within an MBA Program

Abstract: This paper details one business school’s experiences in devel-oping and offering an experiential learning course for MBA students nearing the completion of their programs of study. The course was designed to provide students with opportunities to work with external clients to assist them with strategic issues facing their organizations. While the benefits of the course are numerous, the primary benefit to the student is practical experi-ence in solving real-world problems using skills acquired through their MBA program. In addition, the clients receive (at no cost to them) consulting services from students who bring fresh and innovative perspectives to their organizations. A resultant benefit to the School is an enhanced image within the external business community due to the positive interaction between students, faculty, and clients. This paper provides readers with a wealth of information on course structure, as well as a full description of issues that must be addressed to ensure a positive learning experience for students and a benefi-cial consulting product for the clients.

Strain-induced energy band gap opening in two-dimensional bilayered silicon film

Abstract: This work presents a theoretical study of the structural and electronic properties of bilayered silicon film (BiSF) under in-plane biaxial strain/stress using density functional theory (DFT). Atomic structures of the two-dimensional (2-D) silicon films are optimized by using both the local-density approximation (LDA) and generalized gradient approximation (GGA). In the absence of strain/stress, five buckled hexagonal honeycomb structures of the BiSF with triangular lattice have been obtained as local energy minima, and their structural stability has been verified. These structures present a Dirac-cone shaped energy band diagram with zero energy band gaps. Applying a tensile biaxial strain leads to a reduction of the buckling height. Atomically flat structures with zero buckling height have been observed when the AA-stacking structures are under a critical biaxial strain. Increase of the strain between 10.7% and 15.4% results in a band-gap opening with a maximum energy band gap opening of ∼0.17 eV, obtained when a 14.3% strain is applied. Energy band diagrams, electron transmission efficiency, and the charge transport property are calculated. Additionally, an asymmetric energetically favorable atomic structure of BiSF shows a non-zero band gap in the absence of strain/stress and a maximum band gap of 0.15 eV as a −1.71% compressive strain is applied. Both tensile and compressive strain/stress can lead to a band gap opening in the asymmetric structure.

Elemental abundances of the field horizontal-branch stars – II

Abstract: Studies of one to three 55-A regions recently obtained with a CCD at the coude feed telescope of the Kitt Peak National Observatory are used to extend the fine analyses of the field horizontal-branch (FHB) A stars HD 86986 and 130095 and to begin those of HD 74721 and 117880. The spectra of the Population I B star τ Her and the FHB stars HD 109995 and 161817 show a 4 per cent systematic difference in equivalent widths compared to co-added spectra obtained at the Dominion Astrophysical Observatory. However, this difference is smaller than that previously found using another wavelength region

FCAPT uvby Photometry of the mCP Stars BN Cam, EP Vir, FF Vir, and HD 184905

Abstract: We studied differential single-channel Stromgren uvby observations of four magnetic CP (mCP) stars, obtained with the Four College Automated Photoelectric Telescope (FCAPT), which now have two epochs of observations. To bring the recent photometry of BN Cam into agreement with earlier FCAPT photometry, we adjusted its period to 2.73501 days. As we found several older photometric studies whose data are consistent with this value, its period appears to have been constant for the past 35 years. We refined the period of EP Vir to 16.3071 days and reduced the errors in its ephemeris. When we compare the light curves from the observing seasons in which complete light curves were obtained, we find the small differences among them to be suggestive of variability. For FF Vir and HD 184905, the periods are 129.99 and 1.84535 days, respectively, as found by previous FCAPT data studies. Their light curves are similar to those of previous uvby and V measurements for the past 35 years. Online material: color figures, extended table
