Role Of Perceived Value, Customer Expectation, Corporate Image And Perceived Service Quality On The Customer Satisfaction

This study sets out to investigate the influence of perceived value, customer expectation, corporate image and perceived service quality on the customer satisfaction particularly in Pakistan telecommunication industry. To test the conceptual framework, multiple regression has been used to analyze the data collected from 450 respondents of Pakistan telecommunication companies operating in the Pakistan. This study reveals number of notable findings including the empirical verification that perceived value, customer expectation and corporate image significantly enhancing the customer satisfaction. We also observed that perceived service quality is negatively related to customer satisfaction but insignificant. Furthermore results shows that gender provides no basis for differentiation among variables in determining the customer satisfaction

Comparison of Residual based Cointegration Tests: Evidence from Monte Carlo

In this article ten cointegration tests based on residuals of cointegrating equation are compared on basis of stringency criterion: a robust technique for comparison of tests using Monte Carlo simulations. Two tests i.e. Phillips and Ouliaris’ Pu and Choi Durbin-Hausman statistic are the leading performers and are recommended for any sample size. The remaining eight tests are recommended for only large sample sizes of 200 or greater. The use of all these ten tests is not recommended when presence of both intercept and linear time trend is assumed in cointegrating equation unless the sample size is very large i.e. greater than 200

Bandstop Filter Design for GSM Shielding Using Frequency Selective Surfaces

In this paper, the performance of bandstop Frequency Selective Surface (FSS) is presented which can be used to provide wireless security on airports and other sensitive places, where a mobile phone can be used to set-off an explosive device. It can also be used to block the mobile signals at the places of worship, hospitals and cinemas where the annoying voice of a mobile phone may irritate the masses. The FSS unit cell consists of two metallic square-loop elements printed on FR-4 substrate with different periodicities. The outer and inner square-loop elements are tuned to 900 MHz and 1800 MHz, respectively. It has a stable frequency response at oblique incidences for both perpendicular (TE) and parallel (TM) polarizations. Simulation results are presented to give an overview for the performance of proposed FSS design.DOI:http://dx.doi.org/10.11591/ijece.v2i6.182

ASSESSMENT OF THE EXTENT OF MYOPIA AND ITS ASSOCIATED FACTORS IN CHILDREN OF AGE BETWEEN 6 TO 12 YEARS

Background: The main reason of visual disability is myopia that can be avoided. Objective: The goal of this research study was to assess the extent of myopia and its associated factors in children of age between 6 to 12 years. These children were presented to ophthalmology outpatient of Sir Ganga Ram Hospital, Lahore. Patients and methods: From 1st July, 2017 to 30th June 2018, this research study was organized. The children selected for this study were between 6 to 12 years. The study was carried out in ophthalmology outpatient department of Sir Ganga Ram Hospital, Lahore. Written agreement was sign by the parents of children visiting Ophthalmology outpatient department. Ethical committee of the Hospital accepted the consent. By means of questionnaire, factors that were associated with the disease were noted. Personal information f every child selected for study, was assembled. In this way by using Snellen’s chart, sensitivity of each child wa] noticed. 1% cyclopentolate eye drops were used for these children who were observed sensitivity less than 6/6. Then these children experience refraction. Refraction was carried out by means of retinoscopy. If any dissimilarity was presented, it was examined through chi square test. SPSS-21 was employed for data entry and assessment. The value of P was <_0.05 which was considered valuable. Results: Total children selected for study were 2936. The percentage of female was 67.37%.The percentage of children between 6 -8 years, 9-11 years and 12 years of age was 32.86% , 54.67% and 12.47 respectively. The percentage of myopic children was 57.93%. The time duration of TV watching was ≤1 hour per day, 2-4 hours and >4 hours in 62.39% ,35.62% and 2.02% children respectively. The percentage of the children were playing games or using computer for 1 hour was 60.72% ,35.66% for 2-4 hours and 3.62% for >4 hours. 17.3% children were reading for ≤1 hours, 76.22% fir 2-8 hours and 6.48% for>8 hours. The family background of 65.8% children was positive for myopia. Conclusion: Work and myopia had strong association. Parental myopia was also linked to myopia. Keywords: Myopia, Risk factors, Reading hours

MagNet: Discovering Multi-agent Interaction Dynamics using Neural Network

We present the MagNet, a neural network-based multi-agent interaction model to discover the governing dynamics and predict evolution of a complex multi-agent system from observations. We formulate a multi-agent system as a coupled non-linear network with a generic ordinary differential equation (ODE) based state evolution, and develop a neural network-based realization of its time-discretized model. MagNet is trained to discover the core dynamics of a multi-agent system from observations, and tuned on-line to learn agent-specific parameters of the dynamics to ensure accurate prediction even when physical or relational attributes of agents, or number of agents change. We evaluate MagNet on a point-mass system in two-dimensional space, Kuramoto phase synchronization dynamics and predator-swarm interaction dynamics demonstrating orders of magnitude improvement in prediction accuracy over traditional deep learning models.Comment: Accepted manuscript by ICRA 202

The Role of Organizational Strategies, Social Support, and Technological Capabilities in International Marketing Channel Performance

Information communication technologies increase the competitive intensity among organizations. The only way to get a sustainable competitive advantage is to focus on their resources, and capabilities to establish, and implement effective strategies to increase international marketing channel performance (IMCP). The target population of this study is the food industry in Pakistan, and the sample size is 400. Data has been collected through survey method based on an adapted questionnaire. Data has been analyzed through partial least square – structural equation modeling (PLS-SEM) method. Results showed that validity and reliability of data, and organizational strategies (OS) focused on relationship strategies (RS) and marketing integration strategies (MIS) has positive and significant effect on IMCP. Whereas, technological capabilities (TC) has moderated and significant effect between OS and IMCP. Furthermore, social support (SS) has insignificant effect.  This study has theoretical and practical significance. Because this study opens the new horizons in literature and provide guidelines to align their strategies with their capabilities to gain sustainable competitive advantage, which will improve their IMCP.Â
