Repeated Interaction in Teams: Tenure and Performance
Authors: Villas-Boas J. Miguel 
Published: October 2019

Many of the activities performed in firms are done by teams, where a common output is observed, but outsiders cannot observe the individual contributions of each team member. This leads to the possibility of some of the members of the team free-riding on the contributions of others. Repeated interactions of a team can then potentially lead to cooperation among the members of the team under the credible threat of returning to a free-riding equilibrium. However, repeated interaction under cooperation of a team may lead to decreasing overall output over time because the benefits of the team working together may exogenously decrease over time. This then leads to the optimal duration of a team being finite but stochastic, creating inefficiency, but being sufficiently long so that the elements of the team have an incentive to cooperate. This provides a theory of successive team formation and termination in a firm. The possibility for a too long duration for full team cooperation may then lead the firm to reduce the extent of team cooperation, to be able to reduce the expected duration of a team, and have fewer losses of the team lasting for too long.

The Structure of Health Incentives: Evidence from a Field Experiment
Authors: Carrera Mariana , Royer Heather , Stehr Mark , Sydnor Justin 
Published: October 2019

A growing number of firms use incentive programs to encourage healthy behaviors, but there is little evidence about how such incentives should be structured over time. We explore this issue using a large field experiment that incentivized employees of a Fortune 500 company to use their workplace gym. We compare the effectiveness of a treatment with constant incentives over 8 weeks to two treatments that varied incentives over time. One variable treatment featured front-loaded incentives, which could, in theory, help procrastinators overcome startup costs to joining an incentive program. We find, however, that the front-loaded incentive did not increase participation on the extensive margin relative to the constant incentive and was less effective in sustaining exercise over time. The second variable incentive was designed to leverage short-term habit formation by turning incentives on and off over a longer period of time. This novel sporadic incentive showed slightly stronger effects than the constant incentive. We discuss how the nature of habit-formation processes affects the relative benefits of consistent versus periodic incentives. This paper was accepted by Uri Gneezy, behavioral economics.

Authors: Morowati Sharifabad Mohammad Ali , Rafati Fard Mohammad , Fattahi Ardakani Mojtaba , Dehghani Ahmadabad Ali , Sotudeh Ahmad 
Published: October 2019

Abstract

Background
Nurse-patient communication is one of the most important care relationships that affects the treatment process. The health action process approach (HAPA) has been used to explain a number of behaviors. However, this approach has not been used to explain nurse-patient communication. Therefore, this study was conducted to investigate effective nurse-patient communication using this approach.

Materials and methods
In this cross-sectional study, 300 nurses from public hospitals in the center of Iran were enrolled in the study. A researcher-developed questionnaire was used to measure the HAPA constructs. The data were analyzed using Pearson’s correlation coefficient and one-way analysis of variance with least significant difference (LSD) post hoc tests in SPSS as well as structural equation modeling using AMOUS software.

Results
In the motivation phase, risk perception, outcome expectancies and task self-efficacy predicted 19% of variance in intention to communicate effectively. In the volitional phase, planning and action self-efficacy predicted 22% of variance in effective communication. The scores of HAPA constructs were different depending on the levels of effective communication.

Conclusions
The model can serve as a reference framework to promote effective nurse-patient communication.
Runtime analysis of discrete particle swarm optimization algorithms: A survey
Authors: Mühlenthaler Moritz , Raß Alexander 
Published: October 2019

Abstract
A discrete particle swarm optimization (PSO) algorithm is a randomized search heuristic for discrete optimization problems. A fundamental question about randomized search heuristics is how long it takes, in expectation, until an optimal solution is found. We give an overview of recent developments related to this question for discrete PSO algorithms. In particular, we give a comparison of known upper and lower bounds of expected runtimes and briefly discuss the techniques used to obtain these bounds.
Understanding the effects of temporal energy-data aggregation on clustering quality
Authors: Trittenbach Holger , Bach Jakob , Böhm Klemens 
Published: October 2019

Abstract
Energy data often is available at high temporal resolution, which challenges the scalability of data-analysis methods. A common way to cope with this is to aggregate data to, say, 15-minute-interval summaries. But it often is not known how much information is lost with this, i. e., how good analysis results on aggregated data actually are. In this article, we study the effects of aggregating energy data on clustering. We propose an experimental design to compare a wide range of clustering methods found in literature. We then introduce different ways to compare clustering results obtained with different aggregation schemes. Our evaluation shows that aggregation affects the clustering quality significantly. Finally, we propose guidelines to select an aggregation scheme.
Mechanistic Assessment of Fatigue Performance and Cost Analysis of Pavement Overlays: Comparison between Conventional Hot Mixed Asphalt, Asphalt Rubber, and Polymer-Modified Mixtures
Authors: Gc Hemant , Souliman Mena I. , Zeiada Waleed , Isied Mayzan 
Published: October 2019

Abstract
Fatigue cracking, which is commonly associated with repeated traffic loading, is considered one of the major distresses occurring in asphalt pavements because of the low tensile strength of hot mixed asphalt (HMA). Studies have shown that introducing modifiers, such as rubber and polymers, increases the tensile strength of HMA, prolonging the fatigue life of pavement. Although research in the past has studied the effect of added rubber and polymers on the long-term fatigue performance of newly constructed pavement, few studies have shown the effect of those modifiers on the fatigue life of an asphaltic overlay and their associated cost-effectiveness. In this study, the long-term fatigue performance of asphalt overlay was constructed utilizing three different mixtures, conventional HMA, asphalt rubber (AR), and polymer-modified mixtures, which were evaluated utilizing 3D Move Analysis software. In addition, cost-effectiveness analysis was performed. Eighteen 3D Move Analysis scenarios were run including two different overlay thicknesses, three different vehicle speeds, and three different overlay mixtures. The tensile strain at the bottom of the overlay was determined and the number of fatigue loading cycles to failure (Nf) was calculated based on strain-Nf relationships of the three asphalt mixtures. Based on these analyses, use of modified mixtures as an overlay resulted in a significant increase in the service life of the overlay. It was demonstrated that AR and polymer-modified mixtures had better fatigue life and were more cost-effective than the conventional HMA mixtures.
Functional Interactions of Ribosomal Intersubunit Bridges in Saccharomyces cerevisiae
Authors: Tamm Tiina , Kisly Ivan , Remme Jaanus 
Published: October 2019

Abstract
Ribosomes of Archaea and Eukarya share higher homology with each other than with bacterial ribosomes. For example, there is a set of 35 r-proteins that are specific only for archaeal and eukaryotic ribosomes. Three of these proteins—eL19, eL24, and eL41—participate in interactions between ribosomal subunits. The eukaryote-specific extensions of r-proteins eL19 and eL24 form two intersubunit bridges eB12 and eB13, which are present only in eukaryotic ribosomes. The third r-protein, eL41, forms bridge eB14. Notably, eL41 is found in all eukaryotes but only in some Archaea. It has been shown that bridges eB12 and eB13 are needed for efficient translation, while r-protein eL41 plays a minor role in ribosome function. Here, the functional interactions between intersubunit bridges were studied using budding yeast strains lacking different combinations of the abovementioned bridges/proteins. The growth phenotypes, levels of in vivo translation, ribosome–polysome profiles, and in vitro association of ribosomal subunits were analyzed. The results show a genetic interaction between r-protein eL41 and the eB12 bridge-forming region of eL19, and between r-proteins eL41 and eL24. It was possible to construct viable yeast strains with Archaea-like ribosomes lacking two or three eukaryote-specific bridges. These strains display slow growth and a poor translation phenotype. In addition, bridges eB12 and eB13 appear to cooperate during ribosome subunit association. These results indicate that nonessential structural elements of r-proteins become highly important in the context of disturbed subunit interactions. Therefore, eukaryote-specific bridges may contribute to the evolutionary success of eukaryotic translation machinery.
Effect of Variable Thermal Conductivity on Buoyant Convection in a Cavity with Internal Heat Generation
Authors: Sivasankaran S. 
Published: October 2019

A numerical study has been made to analyze the effects of variable thermal conductivity on the natural convection of heat generating fluids contained in a square cavity with isothermal walls and the top and bottom perfectly insulated surfaces. The flow is assumed to be two-dimensional. Calculations are carried out by solving governing equations for different parameters. The flow pattern and the heat transfer characteristics inside the cavity are presented in the form of steady-state streamlines, isotherms and velocity profiles. The heat transfer rate is increased by an increase in the thermal conductivity parameter.

Authors: Kandaswamy P. , Lee J. , Abdul Hakeem A. K. K. 
Published: October 2019

Natural convection heat transfer in a square cavity induced by heated plate is studied numerically. Top and bottom of the cavity are adiabatic, the two vertical walls of the cavity have constant temperature lower than the plate’s temperature. The flow is assumed to be two-dimensional. The discretized equations were solved by finite difference method using Alternating Direction Implicit technique and Successive OverRelaxation method. The study was performed for different values of Grashof number ranging from 103 to 105 for different aspect ratios and position of heated plate. Air was chosen as a working fluid (Pr = 0.71). The effect of the position and aspect ratio of heated plate on heat transfer and flow were addressed. With increase of Gr heat transfer rate increased in both vertical and horizontal position of the plate. When aspect ratio of heated thin plate is decreased the heat transfer also decreases. For the vertical situation of thin plate heat transfer becomes more enhanced than for horizontal situation.

This paper presents computational modeling of response kinetics of bioelectroanalytical system based on the interfacial action of enzyme lipase. The model also assumes that the substrate of enzyme is located on the surface of micelles which are spread in the solution under study. Two distinct mathematical models have been developed and evaluated through computational simulation series. The results of simulation demonstrate that diffusion is important factor for the sensitivity of bioelectroanalytical system, and it is important to take this process of mass transfer into account in all system areas.

Authors: Bhargava R. , Takhar H. S. S. , Rawat S. , Bég Tasveer A. A. , Bég O. Anwar Anwar 
Published: October 2019

The present analysis is motivated by the need to elucidate with more accuracy and sophistication the hydrodynamics of non-Newtonian flow via a channel containing a porous material under pulsating pressure gradient. A one-dimensional transient rheological model for pulsating flow through a Darcy-Forcheimmer porous channel is used. A modified Casson non-Newtonian constitutive model is employed for the transport fluid with a drag force formulation for the porous body force effects. The model is transformed and solved using a finite element numerical technique. Rheological effects are examined using a β parameter which vanishes in the limit (Newtonian flow). Velocity profiles are plotted for studying the influence of Reynolds number, Darcy number, Forchheimer number and the β (non-Newtonian) parameter. The channel considered is rigid with a pulsatile pressure applied via an appropriate pressure gradient term. The model finds applications in industrial filtration systems, pumping of polymeric fluids etc.

Published: October 2019

We construct the Fučik spectrum for some second order boundary value problem with nonlocal boundary condition. This spectrum differs essentially from the known Fučik spectra. We apply this result to the second order differential equation x'' + g(x) = f(t, x, x') with the conditions x(a) = 0, ∫ab x(s)ds = 0.

Published: October 2019

Computational quantum chemistry helps us to determine, calculate, and study new concepts, compounds, reactions and mechanisms. Such way is very useful with compounds that require exceptionally care in their handling, such as explosives, decreasing risk to persons testing and maintenance costs in service. Computational quantum chemistry is the ground of molecular modeling, on prediction the behavior of individual molecules within a chemical system. The molecular modeling let us to obtain the molecular characteristics comparable with experimental date. In this way the molecular structures of for positional isomers of 2,4,6-trinitrotoluene (TNT) were calculated by an ab initio HF/6-31G∗ method using self made local area personal computer (PC) cluster TAURAS. The cluster was made from heterogeneous commodity hardware of teaching class and for high performance computing (HPC) was used the SCore cluster system software developed in Japan. The structure and the features of the cluster are described and the performance is evaluated during solving of linear algebra testing tasks. During the determination of the structures of the positional isomers of TNT, the deformation of the phenyl ring and the distortions of the nitro and methyl groups were concern. The calculations confirmed that both of these were affected by the positions of nitro groups. A comparison of the calculated energies of all the isomers revealed the tendency to form the stable isomers when the close contact effects of the nitro groups were reduced.

Authors: Dubey B. 
Published: October 2019

In this paper, a mathematical model is proposed and analysed to study the dynamics of a prey-predator model. It is assumed that the habitat is divided into two zones, namely free zone and reserved zone. Predators are not allowed to enter into the reserved zone. Criteria for the coexistence of predator-prey are obtained. The role of reserved zone is investigated and it is shown that the reserve zone has a stabilizing effect on predator-prey interactions.
Unsteady Mixed Convection Flow in the Stagnation Region of a Three Dimensional Body Embedded in a Porous Medium
Authors: Ibrahim F. S. S. 
Published: October 2019

An analysis is preformed to study the heat transfer characteristic of unsteady mixed convection flow of a viscous fluid in the vicinity of a stagnation point of a general three-dimensional body embedded in a porous media. The velocity in the potential flow is assumed to vary arbitrary with time. The non-Darcy effects including convective, boundary and inertial effects are included in the analysis. Both nodal-point region (0 ≤ c ≤ 1), where c = b/a is the ratio of the velocity gradients in y and x directions in the potential flow and saddle point region (−1 ≤ c < 0) are considered. The semisimilar solutions of the momentum and energy equations are obtained numerically using finite difference method. Also a self-similar solution is found when the velocity in the potential flow and the wall temperature vary with time in particular manner. Many results are obtained and a representative set is displayed graphically to illustrate the influence of the physical parameters on the surface shear stresses and the surface heat transfer.
Vector Additive Decomposition for 2D Fractional Diffusion Equation
Authors: Abrashina-Zhadaeva N. , Romanova N. 
Published: October 2019

Such physical processes as the diffusion in the environments with fractal geometry and the particles’ subdiffusion lead to the initial value problems for the nonlocal fractional order partial differential equations. These equations are the generalization of the classical integer order differential equations.
An analytical solution for fractional order differential equation with the constant coefficients is obtained in [1] by using Laplace-Fourier transform. However, nowadays many of the practical problems are described by the models with variable coefficients.
In this paper we discuss the numerical vector decomposition model which is based on a shifted version of usual Gr¨unwald finite-difference approximation [2] for the non-local fractional order operators. We prove the unconditional stability of the method for the fractional diffusion equation with Dirichlet boundary conditions. Moreover, a numerical example using a finite difference algorithm for 2D fractional order partial differential equations is also presented and compared with the exact analytical solution.

Published: October 2019

This paper presents the synthesis and analysis of the enhanced predictive fuzzy Hammerstein model of the water tank system. Fuzzy Hammerstein model was compared with three other fuzzy models: the first was synthesized using Mamdani type rule base, the second – Takagi-Sugeno type rule base and the third – composed of Mamdani and Takagi-Sugeno rule bases. The synthesized model is invertible so it can be used in the model based control. The fuzzy Hammerstein model was synthesized to eliminate disadvantages of the other fuzzy models. The advantage of the fuzzy Hammerstein model was experimentally proved and presented in this paper.
