Selective Attention as a Determinant of Escalation Bias in Subjective Performance Evaluation Judgments
Authors: Kramer Stephan , Maas Victor S. 
Published: November 2019

ABSTRACT
We use an experiment to examine escalation bias in subjective performance evaluations. Participants assume the role of manager and evaluate the performance of an employee based on a balanced-scorecard-type performance report. We manipulate whether managers recommended positively or negatively about the evaluated employee's promotion to his current position. Consistent with the presence of escalation bias, we find that managers give higher performance ratings to employees about whom they advised positively than to employees about whom they advised negatively. Using eye-tracking data, we investigate whether escalation bias arises because managers with different prior commitments toward the evaluated employee pay attention to different items in the scorecard. We find that evaluators' prior recommendation does not affect what proportion of their visual attention is given to favorable (versus unfavorable) performance measures, and that the relative attention paid to favorable measures is not associated with the performance rating.

Authors: Murthy Uday S. , Smith Thomas J. , Whitworth James D. , Zhang Yiyang 
Published: November 2019

ABSTRACT
This study investigates the consequences of information systems compatibility between the target and acquirer firms in the context of mergers and acquisitions (M&A). Using a unique data set of ERP implementations, we find that acquirers using the same ERP vendor as their targets exhibit shorter post-merger operating cycles and shorter post-merger audit delays relative to acquirers with different ERP vendors than their targets. In supplemental analysis, we find evidence that acquirers with the same ERP vendor as their target also exhibit more accurate management forecast guidance following the acquisition. The findings of this study should be of interest to capital market participants and managers involved in M&A activity by providing evidence about how the degree of compatibility between acquirer and target ERP systems impacts post-merger activities across different economically significant functional areas.
Compensation Disclosures and Corporate Governance through Shareholder Voting
Authors: Cadman Brian , Carrizosa Richard , Peng Xiaoxia 
Published: November 2019

ABSTRACT
There are several measures of equity compensation that may provide shareholders with distinct and useful information for evaluating CEO pay. We examine whether shareholders consider additional disclosures of equity compensation measures beyond the grant date fair value when participating in corporate governance. We find that CEO equity compensation expense, a distinct measure of equity compensation, is a determinant of shareholder voting for management sponsored equity plans and voting for directors that serve on the compensation committee. After controlling for ISS recommendations, we find that voting outcomes remain significantly related to abnormal equity compensation expense. Consistent with shareholders considering the equity compensation expense, we document that firms shorten equity compensation vesting periods when they are no longer required to disclose the equity compensation expense. Our findings suggest that shareholders rely on multiple, distinct measures of equity compensation when participating in corporate governance.

Asociación entre confianza e influencia negativa con el rendimiento académico como desencadenante de la deserción escolar en la educación media superior
Authors: Lozano Treviño David Fernando , Maldonado Maldonado Lauro 
Published: November 2019

La deserción en la educación media superior es uno de los retos más grandes en materia escolar que tienen las autoridades mexicanas. Analizar los factores que la causan es de sumo interés tanto para comprender el fenómeno como para proponer estrategias y líneas de acción para abatirla.
El objetivo de la presente investigación fue señalar la asociación que existe entre los constructos de confianza e influencia negativa con el rendimiento académico que lleva a la deserción escolar en la educación media superior. El estudio fue no experimental, descriptivo y correlacional, con una muestra de 2881 desertores en los 32 estados de México, los cuales se agruparon por regiones. Se corrió una regresión lineal múltiple con los factores independientes Confianza e Influencia negativa, y Rendimiento académico como factor dependiente. Se propuso un modelo teórico que refleja las variables comprendidas en los factores. Los resultados mostraron que no existe asociación entre aquellos dos con este último, el rendimiento académico que lleva a la deserción escolar en el nivel medio superior, por lo que no se planteó un modelo empírico.
Lo cierto es que la confianza que un alumno tenga en sus autoridades escolares, profesores, padres de familia y amigos, así como la influencia que estos ejerzan en los primeros, tiende a beneficiar sus asistencias, promedios y aprobaciones, pero son otros factores los que sólidamente se asocian con el rendimiento académico que lleva a la permanencia o deserción escolar en el nivel educativo ya mencionado.

Authors: Rodelo Pérez Jesús Manuel 
Published: November 2019

El objetivo de este trabajo fue caracterizar y explicar los conocimientos y saberes presentes en las prácticas de enseñanza de los docentes universitarios. A partir del análisis de las narrativas de los profesores en torno a sus conocimientos, saberes y experiencias en el campo de la docencia, se buscó aprehender las maneras en que los profesores universitarios construyen dichos saberes. Con base en una metodología cualitativa se aplicaron 40 entrevistas abiertas no estructuradas a docentes de la Universidad Autónoma de Occidente de la Unidad Regional Culiacán. La muestra se conformó con base en un listado de los atributos esenciales de los sujetos objeto de estudio, siguiendo el procedimiento que Goetz y LeCompte (1988) denominan como una selección basada en criterios.
En los resultados, los docentes reconstruyen sus actos docentes en un ejercicio reflexivo; es a partir de ello que se manifiestan los saberes disciplinarios como ejes de su enseñanza, mientras que los saberes pedagógicos permanecen al margen. Estos se hacen más bien presentes en los recursos y dispositivos con las cuales los profesores, en el ámbito de su acción pedagógica, desarrollan estrategias de acción que facilitan los procesos de enseñanza-aprendizaje.

Properties of AlMg3 Aluminium Alloy Joints Welded by Electron Beam Melting
Authors: Czechowski Mirosław 
Published: November 2019

Abstract
Electron beam welding, called electron welding consists in penetrating the elements being welded with heat obtained from the elements’ bombardment in vacuum with concentrated electron beam of high energy. Concentration of the electron beam of high kinetic energy in a very small space results in generating the heat of high concentration causing melting of material in high depth. During the metal melting the electron beam makes a narrow weld of little heat affected zone (HAZ). This paper presents the test results on selection of parameters of electron beam welding of 12 mm thickness sheets of AlMg3 aluminum alloy. The beam electron melting through was carried out in vacuum by means of the welding machine WS-15 KW/100 KV. Before melting, the sheets were degreased in tetrachloroethylene and oxides were removed with 15% solution Na2Co3. The influence of electron beam melting through of sheets on their mechanical properties was tested as well as resistance to stress corrosion cracking and resistance to corrosion in fast seawater flow (10 m/s). The slow strain rate stress corrosion tests in the air and artificial seawater were performed. It was found that electron beam melting through of the AlMg3 alloy does not decrease the mechanical properties in comparison to the native material. The crack during the static tension test had ductile character and proceeded in the native material. AlMg3 alloy melting with electron beam shows a very good stress corrosion resistance.
The Effect of Parameters and Geometry Cutting Edge After Turning of the Duplex Cast Steel on the Maximum Tool Flank Wear
Authors: Dyl Tomasz Cyryl 
Published: November 2019

Abstract
It is important to shape the required properties of the surface layer in the technological process. This issue is an important problem due to the ability of the kinematic pair elements to the required reliable operation of machine parts. The latest generation devices work with increasing operational loads. This forces the search forever-newer construction materials or innovative manufacturing engineering technologies that would ensure high reliability and durability of machine components. For mechanical engineering, continue to be used on steel structures of machine parts. In the petrochemical and shipbuilding industry, stainless steels are very poplars. Those materials are used in the constructions of seawater and acid installations. Currently, a newer material with more favourable properties is two-phase stainless steel. This is the so-called duplex steel. It can be applied to pump shafts in acid or seawater solutions. Duplex cast steel is a difficult-to-cut material. It is important to determine the effect of cutting parameters on the surface quality of the shafts and wear of cutting edge. Traditional methods of finishing surface treatment of shafts are machining (turning, grinding, superfinishing). Considering the possibilities of equipping a marine power plant workshop, it would be best to use machining by turning.
The paper specifies the relationship between the wear of the cutting edge and the geometrical structure of the machined surface as well as the type of tool material used and the shape of the cutting inserts.
Quadrotor UAV Control for Transportation of Cable Suspended Payload
Authors: Kusznir Tom , Smoczek Jarosław 
Published: November 2019

Abstract
Payload transportation with UAV’s (Unmanned Aerial Vehicles) has become a topic of interest in research with possibilities for a wide range of applications such as transporting emergency equipment to otherwise inaccessible areas. In general, the problem of transporting cable suspended loads lies in the under actuation, which causes oscillations during horizontal transport of the payload. Excessive oscillations increase both the time required to accurately position the payload and may be detrimental to the objects in the workspace or the payload itself. In this article, we present a method to control a quadrotor with a cable suspended payload. While the quadrotor itself is a nonlinear system, the problem of payload transportation with a quadrotor adds additional complexities due to both input coupling and additional under actuation of the system. For simplicity, we fix the quadrotor to a planar motion, giving it a total of 4 degrees of freedom. The quadrotor with the cable suspended payload is modelled using the Euler-Lagrange equations of motion and then partitioned into translation and attitude dynamics. The design methodology is based on simplifying the system by using a variable transformation to decouple the inputs, after which sliding mode control is used for the translational and pendulum dynamics while a feedback linearizing controller is used for the rotational dynamics of the quadrotor. The sliding mode parameters are chosen so stability is guaranteed within a certain region of attraction. Lastly, the results of the numerical simulations created in MATLAB/Simulink are presented to verify the effectiveness of the proposed control strategy.

Published: November 2019

Abstract
This paper presents the results of analyses of the series resonance phenomenon in a system containing supercapacitors. The specific features of such components, especially the diffusion processes, cause their dynamic properties significantly differ from those of typical capacitors. In contrast to other authors work, the presented results were obtained during discharging of super-capacitors through periodically changing resistor. Such procedure corresponds to conditions when supercapacitors can be discharged by periodically changing loads. Analysis of resonance phenomena is a very important task; especially in power supply circuits, where supercapacitors often act as energy storage elements. The tests carried out for selected supercapacitors and frequencies range were verified practically using a specially prepared test system.

Published: November 2019

Crumb rubber industry only depends on one main raw material that is called Bahan Olah Karet (Bokar). Based on the observation of several crumb rubber factories in West Sumatera, the company still uses an unsystematic way of choosing the suppliers of bokar. The weakening of the supplier’s supervision system causes bokar that received by the company, in terms of quality and quantity are not met properly. The way to solve these issues is to develop a fuzzy model for supplier assessment of bokar. The first step is the identification of criteria using FDM. Then developing a mathematical model. This research has been successfully developed a mathematical model where FAHP is used to determine the weight of supplier assessment criteria, combined with signed distance at the defuzzification stage. While FTOPSIS is used to obtain suppliers ranking. Through the survey using FDM, we obtain 6 main criteria and 18 subcriteria which relevant to the conditions of the crumb rubber industry in West Sumatera.

Published: November 2019

The primary function of nurses in inpatient services is to provide optimal services for patients with serious illnesses.Therefore, nurses’ job satisfaction should not be taken for granted. The role overload can influence job satisfaction at workplaces. The role overloaand job stress have negative effect. However, the nurses can still have job satisfaction, if the role overload is at low level. The other factor that influences job satisfaction is role ambiguity. The aim of this study is to analyze the factors that determine job satisfaction of nurses, work at the hospital and the job stress impacts on job satisfaction. The samples of this study were 170 respondents. This study applied quantitative design with path analysis. The role overload and job stress have negative and significant influence on job satisfaction. The role overload and role ambiguity have a positive and significant impact on job stress. The role ambiguity does not influence job satisfaction. Job stress mediates the role ambiguity to job satisfaction. The next research can develop variables that can mediate the influence of role ambiguity and role conflict on job satisfaction, for example, burnout and performance variables.
