Integration and the hidden curriculum in business education

Purpose – The principal aim of this paper is to present the case for securing greater affinity between the formal curriculum and the hidden curriculum with respect to integration in business education.Design/methodology/approach – Consideration is given to the concept of the hidden curriculum, as manifested in the compartmentalised nature of academia and the need for this to be offset by business educators. A number of principles for configuring the hidden curriculum in ways that support the goal of integration are suggested.Findings – Some of the literature on the hidden curriculum emphasises the need for consistency in the learning culture so that students' understanding of what their course is seeking to achieve is underpinned by the structures and processes that play an important part in shaping their learning experience.Practical implications – If integration is the goal of business education then attention should be given to creating a learning environment in which its virtues are clearly demonstrat.
Plane-Stress Analysis of the New Stress Tensor Decomposition

The accuracy and reliability of the new stress tensor decomposition to capture the plasticity behaviour of orthotropic materials under plane-stress conditions was examined in this paper. No experiment was required to perform this work. Therefore, the suitable, published paper which provides a relevant test result and sufficient material properties to characterise the new stress tensor decomposition, was used. This new stress tensor decomposition was used to presents a new yield criterion for orthotropic sheet metals under plane-stress conditions in this work. This was done by assuming the yield surface to be circular in the new deviatoric plane. The predictions of the new effectice stress expression were then compared with the experimental data of 6000 series aluminium alloy sheet (A6XXX-T4) and Al-killed cold-rolled steel sheet SPCE. The predicted new yield surfaces are in good agreement with respect to the experimental data for two materials (A6XXX-T4 and SPCE).
Availability of vocational training facilities for the National Directorate of Employment (NDE) in Nigeria

The study adopted the survey design. Sample comprised 1, 200 trainees, 420 trainers and 120 ex-trainees from six states in Southwestern Nigeria using stratified and multi-stage sampling technique. Three instruments titled “NDE Trainees’ Questionnaire (NTeQ), “NDE Trainers’ Questionnaire (NTrQ), and “NDE Ex-trainees’ Questionnaire (NTexQ) for trainees, trainers and ex-trainees respectively were used to collect data. Data were analyzed using descriptive statistics. The results showed that the NDE had about 30 job categories, and that there was inadequate availability of training equipment for the NDE vocational training programmes. The study, among others, recommends that NDE should ensure that trainers procure necessary training facilities for proper impartation of employable skills into the trainees.
MEASUREMENT AND PREDICTION OF HELICOPTER SPRAY NOZZLE ATOMIZATION

Most wind tunnel experiments pertaining to shielded spraying have been conducted under stationary conditions. In field experiments, the interest has always focused on the investigation of drift amount. No information about the effect of a moving shield is available, not to mention the effect of travel speed and travel direction on drift reduction. In this study, by using the FLUENT computational fluid dynamics software package, a double foil shield was used to investigate the effect of a moving shield on drift reduction under different travel speeds and travel directions (upwind and downwind). Related information on conventional spraying without shields was included. In addition, the moving effect of mechanical and pneumatic shields in a three–dimensional flow with only one droplet release nozzle was further compared. Results of this study indicated that local relative velocity plays an important role in controlling the drift potential of a moving sprayer: the higher the local relative velocity, the greater the drift potential. When the sprayer moves upwind, drift potential increases slightly with increased travel speed. However, when the sprayer moves downwind, drift potential decreases inversely with increased travel speed, as long as travel speed is less than wind velocity. For the double foil shield, moving upwind produced less drift potential than moving downwind. Simulation results of comparing three–dimensional shields showed that the double foil shield provided a drift reduction of 60.6% and 29.3% over conventional spraying when traveling upwind and downwind, respectively, at a speed of 1.34 m s –1 . The moving pneumatic shield with the best operating setting provided excellent control of drift reduction for both upwind and downwind traveling at a speed of 1.34 m s –1 .
Direct Numerical Simulations on the three-dimensional wake transition of flows over NACA0012 airfoil at Re = 1000

For micro air vehicles (MAV), the precise prediction of aerodynamic force plays an important role. The aerodynamic force of a comparative low Reynold number (Re) vehicle tends to be affected by the different flow modes. In this paper, the aerodynamic performance of a three-dimensional NACA0012 airfoil is studied numerically. A range of angles of attack (α) 0°−25° and Reynolds number 1000 is considered. Mean and fluctuating coefficients of aerodynamic forces around NACA0012 airfoil are analyzed for different wake modes. The difference of aerodynamic forces between two and three-dimensional simulations are compared. The results show that the wake remains steady two-dimensional for lower angles of attack. At α = 9°, Von Karman vortex pattern is noticed. Flow transition to three-dimensional as the angle of attack increases from α = 13°. 3D wake is found to be stable with parallel shedding mode for 14°-17°. However, these modes become finer with the gradual increase in angle of incidence. While, wake loses its three-dimensional stability to chaotic with gradual increment in angle of attack afterwards.
High glucose removes natural anti-α-galactoside and anti-β-glucoside antibody immune complexes adhering to surface O-glycoproteins of normal platelets and enhances platelet aggregation

Human natural anti-α-galactoside (anti-Gal) and anti-β-glucoside (ABG) antibodies were previously reported to recognize the serine- and threonine-rich peptide sequences (STPS) of albumin-associated O-glycoproteins (AOP1 and AOP2) as surrogate antigens, forming anti-Gal/ABG-AOP1/AOP2-albumin triplet immune complexes in plasma. Since antibodies in these triplets still possessed unoccupied binding sites, the presence of triplets on human platelets that abound in surface O-glycoproteins was examined. Upon treatment with α-galactosides and β-glucosides, normal platelets freshly isolated from young healthy individuals released triplets identical with plasma triplets according to ELISA results. The resulting denuded platelets, unless pre-treated with fibrinogen or the O-glycan-binding lectin jacalin, recaptured these sugar-extracted triplets in the absence of antibody-specific sugars, suggesting that the triplet antibodies recognized the STPS of O-glycosylated receptors on platelets. Molecular weight of the dominant jacalin-binding subunit on triplet-free platelet membrane was 116 kDa, close to the ~120 kDa reported for the IIb subunit of the most abundant fibrinogen-binding platelet O-glycoprotein, GPIIb/IIIa. Denuded, but not native, platelets underwent slow spontaneous aggregation and rapid ADP-mediated GPIIb/IIIa-dependent aggregation according to spectrophotometric assay. Pre-treatment of denuded platelets with jacalin significantly reduced their ADP-mediated aggregation. Amyloid β (Aβ-42 monomer) was reported to bind triplet O-glycoproteins through their STPS but not to albumin or the antibodies. This peptide bound to the triplets on normal platelets and to surface membrane O-glycoproteins on denuded platelets, suggesting that the surface O-glycoproteins on the normal platelets were engaged and masked by the triplets. The ABG-specific sugar glucose denuded the platelets at concentrations typically reached in diabetic sera, since anti-Gal specific or ABG-specific sugar released the triplets of both the antibodies from the platelets. In conclusion, the present study offered rationale for the presence of anti-Gal/ABG-O-glycoprotein-albumin triplets on normal platelets, for the role of triplets in platelet physiology amidst circulating platelet-activating factors such as ADP, and for platelet vulnerability during diabetes.
A Generalized Optimality Criteria Method for Optimization of Additively Manufactured Multimaterial Lattice Structures

Recent progress in Additive Manufacturing (AM) allows for printing customized products with multiple materials and complex geometries that could form the basis of multi-material designs with high performance and novel functions. Effectively designing such complex products for optimal performance within the confines of additive manufacturing constraints is challenging due to the need to consider fabrication constraints while searching for optimal designs with a large number of variables, which stem from new AM capabilities. In this study, fabrication constraints are addressed through empirically characterizing multiple printed materials’ Young’s modulus and density using a multi-material inkjet-based 3D-printer. Data curves are modeled for the empirical data describing two base printing materials and twelve mixtures of them as inputs for a computational optimization process. An optimality criteria method is developed to search for solutions of multi-material lattices with fixed topology and truss cross-section sizes. Two representative optimization studies are presented and demonstrate higher performance with multi-material approaches in comparison to using a single material. These include the optimization of a cubic lattice structure that must adhere to a fixed displacement constraint and a compliant beam lattice structure that must meet multiple fixed displacement constraints. Results demonstrate the feasibility of the approach as a general synthesis and optimization method for multi-material, lightweight lattice structures that are large-scale and manufacturable on a commercial AM printer directly from the design optimization results.
La démarche qualité dans le service public : un exemple d'application dans l'enseignement supérieur

Since its first version published in 1987 the ISO-9001 standard has been in force in various fields, not only in industry. More generally, introducing standards of the “ISO” type into organizations, regardless of their size, has been much discussed and criticized as shown by the specialized literature. More prosaically, this article shuns the never-ending manichean debate over how quality control is implemented in any organization. Rather, we look into how a standard, namely ISO-9001 v 2000, was put into practice within an institution of higher education, as the certification was being applied for, while contemplating the standard’s long-term benefits as well as the difficulties to be met, both from budgetary and human standpoints. As we study organizational constructs, we shall try to see how some originally reluctant key deciders have come to support this approach to change, whose quality has been essential in its success.

Image-based distance and area measuring systems

In this paper, a novel measuring system using a scan-counter method via a CCD camera is proposed. The proposed measuring system is an easy-to-construct system to measure the distance between a CCD camera and an object, and to measure the projected area of the object. This measuring method needs not store huge amounts of image data nor use any pattern recognition approach. It quickly obtains the distance and the projected area using simple circuits and formulas. For distance measurement, two laser projectors are set on either side of a CCD camera and produce two parallel rays that project two bright spots on the object and, therefore, on the CCD. An external clock, which is generated by an extra oscillator, is used to measure the time interval between the two bright spots as the CCD scans the image. A circuit for counting the number of external clock pulses between the two bright spots is employed to calculate the interval between them in the video image. Due to the parallel setup of the distance measuring system, there is a linear relationship between the actual distance and the interval of the two bright spots. Therefore, the actual distance from the CCD camera to the object can be calculated from a simple formula. For area measurement, circuits count the number of external clock pulses of the horizontal scan lines covering the projected area of the object. Then, the projected area of the object is calculated from simple algebraic formulas. Finally, several experimental results demonstrate the effectiveness of the proposed system.
Vertical Variations of Cloud Microphysical Relationships in Marine Stratocumulus Clouds Observed During the ACE‐ENA Campaign

This study examines the vertical variations of cloud microphysical relationships and their implications to cloud microphysical processes in marine stratocumulus clouds using in‐situ aircraft observations during the Aerosol and Cloud Experiments in Eastern North Atlantic (ACE‐ENA) field campaign. A new diagram with a coordinate system based on cloud droplet liquid water content (Lc) and phase relaxation time scale is proposed to investigate mixing mechanisms. This new diagram analysis shows that the inhomogeneous mixing trait is dominant near the cloud top, but homogeneous mixing trait is stronger at lower altitudes. The relevant scale parameters (i.e., transition length scale and transition scale number) also indicate a high likelihood of inhomogeneous mixing. The relationship between Lc and standard deviation of droplet radius (σR) clearly shows the vertical transition: the correlation between Lc and σR is positive at lower cloud altitudes, but it becomes negative as altitude increases. Such a vertical transition is consistent with the vertical circulation mixing, modulating the cloud microphysical relationships to suggest homogeneous mixing at a significant depth from the cloud top.
Flow dynamics and bedload sediment transport around paired deflectors for fish habitat enhancement: a field study in the Nicolet River

Schemes to restore fish habitat in rivers often involve installing instream structures such as current deflectors to create and maintain riffle-pool sequences. However, there is a lack of field studies on the impact of these structures on flow dynamics and bed topography. The objective of this research is to characterize flow dynamics and sediment transport around paired deflectors used to enhance fish habitat in the Nicolet River, Quebec. Bed and bank topography surveys were taken with a total station, and velocity and bed shear stress estimates were obtained from an acoustic doppler velocimeter. Bedload sediment transport was assessed by two methods: tracer rocks (painted "particles" and passive integrated transponder tags) and sediment traps. Results show marked differences in bedload sediment transport patterns between the left bank and the right bank downstream of the deflectors. This is surprising considering that paired deflectors should produce a relatively symmetrical disruption to the flow field.
Self-aligned metal/IDP Si bipolar technology featuring 14 ps/70 GHz

Self-aligned metal/IDP (SMI) technology is proposed to achieve high-speed bipolar transistors. SMI technology produces stacked metal/in-situ doped poly-Si (IDP) base electrodes that have a small thermal budget to obtain low base resistance and a shallow link base for small-collector capacitance and high-cutoff frequency. A 16.2-ps delay time in an ECL ring oscillator, and a delay time of 14.3 ps in a differential ECL ring oscillator were achieved by using SMI technology with an ion-implanted base.
Theory of spontaneous emission noise in open resonators and its application to lasers and optical amplifiers

A theory of spontaneous emission noise is presented based on classical electromagnetic theory. Unlike conventional theories of laser noise, this presentation is valid for open resonators. A local Langevin force is added to the wave equation to account for spontaneous emission. A general expression is found relating the diffusion coefficient of this force to the imaginary part of the dielectric function. The fields of lasers and amplifiers are found by solving the wave equation by the Green's function method. The lasing mode is a resonant state associated with a pole in Green's function. In this way, noise in lasers and amplifiers is treated by a unified approach that is valid for either gain guiding or index guiding. The Langevin rate equations for the laser are derived. The theory is illustrated with applications to traveling wave and Fabry-Perot amplifiers and Fabry-Perot lasers. Several new results are found: optical amplifier noise increases inversely with quantum efficiency; spontaneous emission into the lasing mode is enhanced in lasers with low facet reflectivities; and the linewidth of a Fabry-Perot laser with a passive section decreases as the square of the fraction of the cavity optical length that is active.
Systematic mapping of rRNA 2’-O methylation during frog development and involvement of the methyltransferase Fibrillarin in eye and craniofacial development in Xenopus laevis

Ribosomes are essential nanomachines responsible for protein production. Although ribosomes are present in every living cell, ribosome biogenesis dysfunction diseases, called ribosomopathies, impact particular tissues specifically. Here, we evaluate the importance of the box C/D snoRNA-associated ribosomal RNA methyltransferase fibrillarin (Fbl) in the early embryonic development of Xenopus laevis. We report that in developing embryos, the neural plate, neural crest cells (NCCs), and NCC derivatives are rich in fbl transcripts. Fbl knockdown leads to striking morphological defects affecting the eyes and craniofacial skeleton, due to lack of NCC survival caused by massive p53-dependent apoptosis. Fbl is required for efficient pre-rRNA processing and 18S rRNA production, which explains the early developmental defects. Using RiboMethSeq, we systematically reinvestigated ribosomal RNA 2’-O methylation in X. laevis, confirming all 89 previously mapped sites and identifying 15 novel putative positions in 18S and 28S rRNA. Twenty-three positions, including 10 of the new ones, were validated orthogonally by low dNTP primer extension. Bioinformatic screening of the X. laevis transcriptome revealed candidate box C/D snoRNAs for all methylated positions. Mapping of 2’-O methylation at six developmental stages in individual embryos indicated a trend towards reduced methylation at specific positions during development. We conclude that fibrillarin knockdown in early Xenopus embryos causes reduced production of functional ribosomal subunits, thus impairing NCC formation and migration. AUTHOR SUMMARY Ribosomes are essential nanomachines responsible for protein production in all cells. Ribosomopathies are diseases caused by improper ribosome formation due to mutations in ribosomal proteins or ribosome assembly factors. Such diseases primarily affect the brain and blood, and it is unclear how malfunctioning of a process as general as ribosome formation can lead to tissue-specific diseases. Here we have examined how fibrillarin, an enzyme which modifies ribosomal RNA by adding methyl groups at specific sites, affects early embryonic development in the frog Xenopus laevis. We have revealed its importance in the maturation of cells forming an embryonic structure called the neural crest. Fibrillarin depletion leads to reduced eye size and abnormal head shape, reminiscent of other conditions such as Treacher Collins syndrome. Molecularly, the observed phenotypes are explainable by increased p53-dependent programmed cell death triggered by inhibition of certain pre-rRNA processing steps. Our systematic investigation of the ribosomal RNA 2’-O methylation repertoire across development has further revealed hypomodification at a late stage of development, which might play a role in late developmental transitions involving differential translation by compositionally different ribosomes.
