European Conference on Information Systems ( ECIS ) 5-2-2012 MOTIVATING KNOWLEDGE SHARING BEHAVIOR FROM THE PERSPECTIVE OF THE CONVERTIBILITY OF ECONOMIC BENEFITS

Past research has extensively studied individuals’ knowledge-sharing behavior. Identifying the effective mechanisms that motivate individuals to share their valuable knowledge has become an important issue and a major challenge for researchers and practitioners. Past studies fail to consider the readiness of conversion of motivational mechanism to economic benefits of knowledge sharing on knowledge sharing behavior. This study develops a theoretical model of the convertibility of economic benefits that integrates the calculative-based mechanism (CBM) modified from organizational reward systems and the relational-based mechanism (RBM) founded on social interaction to explain knowledge sharing behavior. The research will be conducted by a field study in collaboration with a district hospital to secure the survey data. The objective of this study is to help answer the following research questions. 1. How does the CBM, which incorporates the construct of organizational reward systems, facilitate knowledge sharing behavior? 2. How does the RBM, which incorporates the construct of deposits, withdrawals, and relationship account balance, facilitate knowledge sharing behavior? 3. Against the benchmark of the CBM, does the addition of the RBM give a better explanation of individual knowledge sharing behavior?
Theoretical and Experimental Investigation of the Voltage Ripple across Flying Capacitors in the Interleaved Buck Converter with Extended Duty Cycle

The interleaved buck converter with an extended duty cycle is analyzed in terms of unexplored parasitic switching states that diminish the switch utilization and its safety due to high-magnitude charging and discharging currents. The analysis explains the origin of the states and their effects and demonstrates their correlation with the existing voltage ripple on flying capacitors. The article further demonstrates that the voltage ripple can no longer be arbitrarily chosen as parasitic states emerge whenever the ripple exceeds an identified critical value being equal to the twofold voltage drop on the diode. A simple design criterion for flying capacitance is proposed. For a limited set of battery-powered DC–DC converters, a solution permitting the use of smaller capacitance by adding an extra switch is proposed. The derived findings are verified using experimental and simulation results.
J un 2 01 8 Explainable Deterministic MDPs

We present a method for a certain class of Markov Decision Processes (MDPs) that can relate the optimal policy back to one or more reward sources in the environment. For a given initial state, without fully computing the value function, q-value function, or the optimal policy the algorithm can determine which rewards will and will not be collected, whether a given reward will be collected only once or continuously, and which local maximum within the value function the initial state will ultimately lead to. We demonstrate that the method can be used to map the state space to identify regions that are dominated by one reward source and can fully analyze the state space to explain all actions. We provide a mathematical framework to show how all of this is possible without first computing the optimal policy or value function.

A new multi‐scale dispersive gradient elasticity model with micro‐inertia: Formulation and 
 C0 ‐finite element implementation

Motivated by nano‐scale experimental evidence on the dispersion characteristics of materials with a lattice structure, a new multi‐scale gradient elasticity model is developed. In the framework of gradient elasticity, the simultaneous presence of acceleration and strain gradients has been denoted as dynamic consistency. This model represents an extension of an earlier dynamically consistent model with an additional micro‐inertia contribution to improve the dispersion behaviour. The model can therefore be seen as an enhanced dynamic extension of the Aifantis' 1992 strain‐gradient theory for statics obtained by including two acceleration gradients in addition to the strain gradient. Compared with the previous dynamically consistent model, the additional micro‐inertia term is found to improve the prediction of wave dispersion significantly and, more importantly, requires no extra computational cost. The fourth‐order equations are rewritten in two sets of symmetric second‐order equations so that C0 ‐continuity is sufficient in the finite element implementation. Two sets of unknowns are identified as the microstructural and macrostructural displacements, thus highlighting the multi‐scale nature of the present formulation. The associated energy functionals and variationally consistent boundary conditions are presented, after which the finite element equations are derived. Considerable improvements over previous gradient models are observed as confirmed by two numerical examples. Copyright © 2016 John Wiley & Sons, Ltd.
Reflectivity and Elastic Modulus of Nano-Aluminum Films on Silicon Crystal Substrates

In this work, effect of film thickness on optical reflection and elastic modulus of the metal film at very low size was studied. We choose Aluminum as a reflective surface where it mostly used as a typical material for micro mirror device due to its high reflectivity. The effect of film thickness on the reflectivity had been performed at the range of 400-700 nm wavelengths for thin film thicknesses between 10 125 nm. The mirror fabricated by depositing the Al films on single crystal silicon (100) substrates using E beam evaporation deposition machine to get optimum flatness that is desired in the mirror fabrication. After that, reflection of the mirrors was measured using UV 2200 Spectrophotometer. Reflection also simulated using a powerful simulation tool, Opti-FDTD finite element package and the results were compared. Both of grain size and surface roughness of the films were measured using Scanning Electron Microscopy (SEM) and Atomic Force Microscope (AFM, tapping mode), respectively, to study the reason of deviation between the simulated and experimental results of reflection. In addition, elastic modulus of the films was measured using nanoindentation method using AFM (Contact mode) and the results compared to bulk value. General increasing in the reflection as the film thickness increased and decrease in the reflection as the wavelength increased was observed. At lower film thickness, 10 nm, the film had very low reflection compared to other films. After comparison between the experiments and the simulation results, it appears that deviation between them increase as the film thickness decrease and the topography of the metal surface is the reason behind that. Finally, elastic modulus of the films were determined and it shows that there is decrease in the films modulus and sharp decrease at 50 nm film thick.

A Meta-Analysis of the International Gender Wage Gap

Since the early seventies, hundreds of authors have calculated gender wage differentials between women and men of equal productivity. Consequently, estimates for the gender wage gap have been published for the most diverse countries at different points in time. This metastudy provides a quantitative review of this vast amount of empirical literature on gender wage discrimination as it concerns differences in methodology, data, countries and time periods. We place particular emphasis on a proper consideration of the quality of the underlying study which is done by a weighting with quality indicators. The results show that data restrictions have the biggest impact on the resulting gender wage gap. Moreover, we are able to show what effect a misspecification of the underlying wage equation – like the frequent use of potential experience – has on the calculated gender wage gap. Over time, raw wage differentials world-wide have fallen substantially; however, most of this decrease is due to an increased labor market productivity of females.
516 mW, nanosecond Nd:LuAG laser Q-switched by gold nanorods

Q-switched operation of an Nd:LuAG laser using gold nanorods (GNRs) as the saturable absorber (SA) is reported, which also produces the highest average power among the nanosecond Nd-doped Q-switched lasers by GNRs-based SA. The applied GNRs are prepared using a seed-mediated growth method and then dropped onto the quartz substrate to fabricate the SA. The average power of the Q-switched laser is 516 mW with the shortest pulse duration of 606.7 ns and the repetition rate of 265.1 kHz.
The time-scale of escape from star clusters

In this paper a cluster is modelled as a smooth potential (due to the cluster stars) plus the steady tidal field of the Galaxy. In this model there is a minimum energy below which stars cannot escape. Above this energy, however, the time-scale on which a star escapes varies with the orbital parameters of the star (mainly its energy) in a way which we attempt to quantify, with both theoretical arguments and computer simulations. Within the limitations of the model we show that the time-scale is long enough to complicate the interpretation of full N-body simulations of clusters, and that stars above the escape energy may remain bound to the cluster for about a Hubble time.
Systematic review of knowledge, attitude, and practices regarding dengue in Malaysia

Several studies had focused on assessing the relationship and description of the level of knowledge, attitude, and preventive practices (KAP) regarding dengue in Malaysia among different districts, different set of people living in rural, semi-urban, and urban areas over the years. This study reviewed the behavioral evidence, differences, and similarities of the KAP studies despite the use of different instruments for data collection and methodologies for the analysis of data. The search for the literature was conducted in January 2018 via the electronic database of PubMed, Scopus, Science Direct, EBSCOhost, ProQuest, and Google Scholar. Open access journals that were published between June 1986 and December 2017 were examined, focusing mainly on Malaysia as a country. Seventeen articles met the inclusion benchmarks. Most studies showed that the high level of knowledge influences good attitude and high preventive practices. Knowledge was mostly attributed to some socio-demographic factors. It is essential to compile the KAP studies regarding dengue which are done in different locations/districts of a country over the years, in order to project into the future on how to disseminate information to mitigate dengue infection and also to know the most influencing factors affecting it.
Theoretical Calculations of Refractive Index of Synthesized One and Two Substituted Derivatives of Functionalized Bithiophene Compounds

In order to study the variation of electronic properties, a set of bithiophene derivatives has been ‎developed. Here, the effect of substitution on the aromaticity properties of some cyclic ‎bithiophene derivative compounds was investigated using theoretical calculations. Calculations ‎were performed at B3LYP/6-31+G (d,p) level; and calculated properties included energy, dipole ‎moment, total charge on sulfur atom, energy gap, hardness and dipole polarizability. ‎Experimental polarizability values were comparable with the theoretical values. Theoretical ‎refractive indices were obtained using average polarizability in Lorentz-Lorentz equation. The ‎results of comparison between theoretical and experimental refractive indices demonstrated that ‎the scaling factors for refractive index and polarizability were 0.99-1.14 and 0.98-1.28, ‎respectively. ‎
Far-infrared spectral energy distribution fitting for galaxies near and far

Spectral energy distribution (SED) fitting in the far-infrared (FIR) is greatly limited by a dearth of data and an excess of free parameters – from galaxies’ dust composition, temperature, mass, orientation, opacity, to heating from active galactic nuclei (AGN). This paper presents a simple FIR SED fitting technique joining a modified, single dust temperature greybody, representing the reprocessed starburst emission in the whole galaxy, to a mid-infrared (MIR) power law, which approximates hot-dust emission from AGN heating or clumpy, hot starbursting regions. This FIR SED can be used to measure IR luminosities, dust temperatures and dust masses for both local and high-z galaxies with three to 10+ FIR photometric measurements. While the fitting technique does not model emission from polycyclic aromatic hydrocarbons (PAHs) in the MIR, the impact of PAH features on integrated FIR properties is negligible when compared to the bulk emission at longer wavelengths. This fitting method is compared to IR template SEDs in the literature using photometric data on 65 local luminous and ultraluminous infrared galaxies, (U)LIRGs. Despite relying only on 2–4 free parameters, the coupled greybody/power-law SED fitting described here produces better fits to photometric measurements than best-fitting literature template SEDs (with residuals a factor of ∼2 lower). A mean emissivity index of β = 1.60 ± 0.38 and MIR power-law slope of α = 2.0 ± 0.5 is measured; the former agrees with the widely presumed emissivity index of β = 1.5 and the latter is indicative of an optically thin dust medium with a shallow radial density profile, ≈r−1/2. Adopting characteristic dust temperature as the inverse wavelength where the SED peaks, dust temperatures ∼25–45 K are measured for local (U)LIRGs, ∼5–15 K colder than previous estimates using only simple greybodies. This comparative study highlights the impact of SED fitting assumptions on the measurement of physical properties such as IR luminosity (and thereby IR-based star formation rate), dust temperature and dust mass, for both local and high-redshift galaxies.
Auditory–Visual Speech Integration in Bipolar Disorder: A Preliminary Study

This study aimed to investigate how individuals with bipolar disorder integrate auditory and visual speech information compared to healthy individuals. Furthermore, we wanted to see whether there were any differences between manic and depressive episode bipolar disorder patients with respect to auditory and visual speech integration. It was hypothesized that the bipolar group’s auditory–visual speech integration would be weaker than that of the control group. Further, it was predicted that those in the manic phase of bipolar disorder would integrate visual speech information more robustly than their depressive phase counterparts. To examine these predictions, a McGurk effect paradigm with an identification task was used with typical auditory–visual (AV) speech stimuli. Additionally, auditory-only (AO) and visual-only (VO, lip-reading) speech perceptions were also tested. The dependent variable for the AV stimuli was the amount of visual speech influence. The dependent variables for AO and VO stimuli were accurate modality-based responses. Results showed that the disordered and control groups did not differ in AV speech integration and AO speech perception. However, there was a striking difference in favour of the healthy group with respect to the VO stimuli. The results suggest the need for further research whereby both behavioural and physiological data are collected simultaneously. This will help us understand the full dynamics of how auditory and visual speech information are integrated in people with bipolar disorder.
Numerical Study of Oxidation in Stainless Steel Alloy Ep-823 by Liquid Lead-Bismuth Eutectic

The oxidation of stainless steel is influenced by the presence of oxygen in the surrounding medium; the oxygen reacts with the alloy to form an oxide. In certain environments, such as nuclear reactor coolant systems, minimal oxidation of the stainless steel containment functions as a protective shield from corrosive coolants such as liquid lead-bismuth eutectic. In the current study, this minimal oxidation is evaluated for a system in which corrosion-resistant stainless steel alloy EP-823 is subject to an environment of flowing oxygenated liquid lead-bismuth eutectic at a temperature of 743 K, whereby the thickness of the forming oxide layer is attributed to diffusion of oxygen within a plane comprised of the alloy. Fick’s second law of diffusion and the advection-diffusion equation in one spatial dimension are utilized as the mathematical model. The diffusion problem attributed to the oxidation of metal alloys introduces complications in the domain due to: the change in density as the oxide is formed, the discontinuity in diffusion coefficients between the oxide and metal phases, and the occurrence of two moving boundaries – one separating the oxide and metal phase and the other, the interior unexposed boundary. These complications are resolved by transformations of: the space coordinate of the interface boundary, the calculating space coordinate, and the space coordinate of interior moving boundary. Hereby, the domain of the mathematical model is fixed. The discontinuity of the diffusion coefficients at the phase boundary is resolved by a final transformation. The implicit numerical scheme applied to the mathematical model is described. This method, termed the ‘enthalpy method’, is typically used for moving boundary phase change problems. The implemented Newton-Raphson iterative technique for this finite difference method and the solution by a tri-diagonal matrix algorithm are also described. Input parameters for the numerical simulation are derived both from physical assumptions and from controlled experiments of the oxidation of EP-823 alloy, which had been previously determined an optimal corrosion-resistant steel [1]. Such parameters include the concentration of oxygen at interface, which is determined by considering the solubility of oxygen in EP-823 alloy. The effective oxidation of the alloy is studied by assessing the oxidation of the alloys component metals. The plausible oxidation reactions and resulting oxides are compiled based on partial pressure of oxygen in lead-bismuth eutectic, temperature, and free energy of formation of the relevant oxides. Hereby, input parameters such as mass fraction of the metal in its component oxide and density of the metal were obtained. The experimentally determined scale removal rate was also used as an input. The diffusivity of oxygen in the oxide and metal phases was estimated based on the physical assumptions of higher porosity in the oxide phase. The numerical results, which are in the form of the oxygen concentration profiles as a function distance
How Stereotypes Impact Women in Physics Two studies by social scientists have discovered evidence of both subtle and blatant stereotyping of women in physics laboratories

W e believe science is rational and unbiased, but is the same true for scientists themselves? In recent years, researchers have begun to question how the culture of the scientific community influences the experiences of those who join it. In a special collection of Physical Review Physics Education Research focused on gender studies, two papers spotlight the ways in which the culture of experimental physics can create an unequal workplace that constrains women’s choices, behavior, and training. Ramón Barthelemy of the University of Jyväskylä, Finland, and colleagues [1] and Allison Gonsalves of McGill University, Canada, and co-workers [2] interviewed students and faculty members at physics labs in several countries, identifying many ways in which stereotypes—both implicit and explicit—affect professional interactions and impact the careers of women.
Application on Partial Substitute of Cement by Bentonite in Concrete

To investigate the potential use of Bentonite to evaluate its impact on various strength of ordinary Portland Concrete (OPC). It was accomplished to raise cement concrete by partially replaced of cement. An OPC batch, properly mix designed was prime; aiming at strength admixtures was also introduced to attain high workability. Normal compressive testing was performed for this purpose and the quality of concrete was checked. It was seen from the results that Bentonite resulted in poor early stage and good later stage Compressive strength when compared with Conventional samples. The bentonite samples were characterized by the main variable proportion of bentonite in the natural and intercalated forms (0, 25, 30, and 35 % by weight of cement for a mix of M25) in the replacement mode whiles the amount of cementations material. At 30% substitute of clay has achieved 19.55%, 2.72% and 8.07% in compressive, split tensile and flexural strength for 28days.
