Academic counseling: a positive analysis for investigating the role of teacher-student interaction at business schools
(Global Business Review, 2005) Ahmed F. Siddiqi
The study investigates the relationship between cognitive and affective outcomes of the quality of teacher-student interaction at different business schools in Pakistan. As early as 1936, Kurt Lewin recognized that the environment was a determinant of human behaviour and performance. Following Lewin s work, Murray proposed a Needs-Press model in which situational variables found in the environment account for a degree of behavioural variance. Attempts were also made to study situational variables found in the environment that affect the learning process, on the one hand, and students professional performance, on the other. A multistage stratified random sampling plan was used to select a sample from business schools at Lahore, Islamabad, Multan and Karachi. Stratification was done first at the ownership level, where the two strata consist of public and private sector schools. At the second stage, three strata were made according to the students' background, where students coming from English-medium schools, semi-English-medium schools and vernacular-medium schools were placed in three strata. In the third stage, the stratification was done on a gender basis. In the final stage, students were selected using systematic sampling. Such a multi-stage stratification plan permitted us to do an in-depth analysis of the whole process of teacher student interaction. The study identifies the types of interactions that are most likely to enhance students progress in business administration courses. It also identifies the important factors inhibiting or encouraging, teacher-student interaction. Further, it provides suggestions to enhance this interaction process.
Achieving energy efficiency in manets by using load balancing approach
(International Journal of Computer Networks and Communications Security, 2015) Junaid A. Khan; M. Nasir Iqbal; Farooq Umer; Muhammad Adnan; Zeeshan A.Khan; Mustafa Shakir
Mobile Ad Hoc networks have no base station and use multihop routing for transmission of data from a source node to its destination node. To make this multi-hop routing mechanism possible we need a routing protocol. We have adopted load balancing technique that can improve the overall performance for communication in a network. We have presented optimum performance for our novel protocol i.e. Energy Efficient Load Balanced (EFLBAODV) and compared it to the traditionally existing reactive routing protocol Ad Hoc on Demand Distance Vector (AODV) thus using the load balancing technique to improve the node to node communication in our network. Also our routing protocol will be energy efficient as it will minimize the communication time and overheads thus utilizing the energy resources. Some important metrics like route discovery time, route errors, MAC delay, network load, end-to-end delay and throughput have been taken to evaluate the overall improvement in the novel protocol.
Active phased array radars as an effective eccm systems
(Progress in electromagnetic research symposium, 2014) Faran Awais Butt; Ahmed Malik; Madiha Jalil
Phased Array Radars have started to regain some serious attention over the past few decades owing to its high accuracy, efficiency and less susceptible characteristics. The most basic requirement that one could wish for in a good modern radar is its beam agility, low distribution loss, maximum bandwidth, lower cost, maximum efficiency and effective resource management. Modern phased array radars can be best utilized to achieve characteristics of an effective radar system with minimum tradeoffs. The most basic thing that it can achieve is, that the antennas can be arranged to get the desired radiation pattern. The characteristics and detection abilities of active phased array radar systems are discussed. Moreover, the paper suggests that active phased array radar can be best suited as an electronic counter-counter measure system.
Ad Hoc Collaboration space for distributed cross device mobile application development using WiFi direct (ACS)
(University of Management & Technology, 2018) Khawaja, Imran Abbas
Over the last few years, we have seen an enormous increase in the usage of electronic devices smart phones, tablets, laptops, TVs and wearables, which are developed by different manufacturer for different platforms. People surrounded by these devices need to interact with them during the meeting, presentation, class room and lots of other collaborative activities to share and receive information across the devices. However, the interaction among these devices is still device centric and dependent on the expensive fixed software and hardware infrastructure. In a situation, where fixed infrastructure service does not exist, suspended or disrupted due to some reasons, the interaction across these devices is not possible. In this study we have presented the framework that provides th network as well as facilitate the development of cross de without using any fixed expensive infrastructure. The n reduced the application development time by hiding the c to use API's for application developer to build distributed development takes extra time and distract the developer to to high complexity level. This framework supports dive of different manufacturer and all interactions are done the nearby devices to communicate with each other with point.
Adolescent girls are hurt more by the body mass than thin-ideal media images of females
(Journal of Behavioural Sciences, 2014) Marium Javaid; Iftikhar Ahmad
This study aimed to identify factors that affect body self-image satisfaction and negative mood among adolescent girls. Positive and Negative Affect Schedule, Self Esteem Scale, Body Image Satisfaction Scale and Figure Rating Scale was administered to 97 female undergraduate students to have a base-line data for the study. Overall, self esteem and body mass predicted body satisfaction significantly. Of these 47 participants volunteered to appear in the second phase of the study as well, after a week, and were shown thin-ideal images of women on power point as an intervention and were asked to complete Positive and Negative Affect Schedule and Body Image States Scale for the second time in view of their recent and fresh feelings and views. It was found that the participants of different body weight showed no change in their body image satisfaction than before except in the case of overweight participants. They were significantly affected on negative mood after viewing the thin ideal images. Comparing three groups with different body mass index, one-way ANOVA revealed significant difference on negative mood as well as body image satisfaction. This revealed body mass (index) is a potent and table factor that could strongly affect body satisfaction. Overall, participants’ actual body mass was a negative predictor of body image satisfaction and self esteem appeared as a moderator of mood affectivity. These results were corroborated with another finding of this study: Participants whose perception of their body shape and that of their ideally desired body shape was markedly discrepant had gone to significantly low level of body image satisfaction as well as self esteem than those with low discrepancy. The thin-ideal images seemed to affect influence body satisfaction and mood of the oversized women more than the average ones.

AKP and the idea of the Turkish Model (2002-14): A longitudinal analysis.
(IPRI Journal, 2016) Sajjad, Fatima
This article examines the evolution of the idea of the Turkish model as constructed by academics from the West, the Muslim world and Turkey during the three consecutive terms of the Justice and Development Party (AKP) rule in Turkey. It focuses on the changing political landscape of Turkey, the Middle East and the world at large during post 9/11 years and the emerging issues and debates around the idea of this model. Based on a careful selection and examination of 145 academic articles on the model published during the extended rule of AKP in Turkey (2002-14), the study illustrates that the term „Turkish model‟ has held disparate meanings and generated diverse debates overtime. The growing political unrest, suppression and violence in and around Turkey during the third phase of AKP rule (2012-14) has significantly undermined the idea which lately held great appeal in the West as well as the Muslim world.
Algebraic properties of the binomial edge ideal of a complete bipartite graph
(An. St. Univ. Ovidius Constanta, 2014) Schenzel, Peter; Sohail Zafar
Let JG denote the binomial edge ideal of a connected undirected graph on n vertices. This is the ideal generated by the binomials xiyj 􀀀 xjyi; 1 _ i < j _ n; in the polynomial ring S = K[x1; : : : ; xn; y1; : : : ; yn] where fi; jg is an edge of G. We study the arithmetic properties of S=JG for G, the complete bipartite graph. In particular we compute dimensions, depths, Castelnuovo-Mumford regularities, Hilbert functions and multiplicities of them. As main results we give an explicit description of the modules of decencies, the duals of local co homology modules, and prove the purity of the minimal free resolution of S=JG.

Aligning the supply chains of educational institutes with business strategy
(PIQC Institute of Quality, 2007) Asher Ramish; Ijaz Yusuf
Schools that offer business subjects or arts in any part of the world either offer quality education leading to high expense or would opt for medium quality education and focusing more on getting economies of scales. Supply chain optimization of educational institutions is highly dependant on number of parameters which I refer to as drivers (e.g. no. of faculty, students, empowerment of faculty etc.), the intensity level of which needs to be gauged always. A common challenge is to not only highlighting those drivers and their inter-dependencies across the business framework of the institution but to seek the line of demarcation in the entire range (intensity) offered by that specific driver. That ONLY would be possible if business strategy is clearly defined. This Paper represents a model based on integration of various causal loop diagrams on selecting the intensity levels of each driver so as to chalk out an appropriate system model aligned and optimized. This model will direct or guide you to fine tune a specific driver to create synchronization and help align your supply chain network with business strategy. We find that by varying the intensity levels of one of the drivers may misalign your educational institution’s supply chain from business strategy and vice versa. An SD model is made formulating a spectrum of education quality, one extreme of which would be a cost effective education system and the other extreme is a high quality education system. The model encompasses all parametric and structural changes in the educational institution. This system model is a true picture of how the institution’s supply chain is aligned with the business strategy and is a useful guide for all managers and administrators of those educational institutions, the supply chain of which is portraying turmoil in contrary to the business strategy.
Analysis and comparison of cope’s performance for various network topologies
(Science International Lahore, 2015) Ayesha Iqbal
COPE is an architecture for wireless mesh networks that improves the overall throughput of a network using opportunistic coding. COPE’s performance has been analyzed by different researchers and modifications to this architecture have been proposed that further improved the throughput of a network. Two simple network topologies were analyzed using COPE in research work presented in [1]. In this research paper, this idea has been extended to three other network topologies. Coding gains for these networks are mathematically formulated and COPE’s performance is analyzed when applied to these networks. On the basis of this analysis, the gains of these networks, which are obtained as a result of opportunistic coding, are compared with each other. Simulation results also help to analyze the performance of networks in COPE and non-COPE cases.
Analysis of gyra mutations in local TB patients of Lahore Pakistan
(2017) Iram Afzal
Tuberculosis is a slowly progressive, debilitating disease that kills about 1.5 million people world-wide. Pakistan ranked 4th in global TB burden. In this research work, male-female ratio showed that the rate of TB is 32 times higher in women as compared to men. The patients suffering from pulmonary TB were 94% and only 6% were recorded as extra pulmonary TB. All the extra pulmonary TB cases were found in females. There were about 72% cases which were positive for MDR-TB. Out of these72% MDR-TB cases,all were previously treated. The differentiation between M. bovis and M. tuberculosis reflects that none of the sample belonged to M. bovis. All the isolates were belonged to M. tuberculosis, but 6% samples had extra-pulmonary TB. It shows that M. tuberculosis not only affects the lungs, but also the other parts of the human body. GyrA mutations were investigated by using newly designed primers, at codons 90, 91, and 94. Results showed that out of all samples there were mutations in 60% samples. There were mutations in 30% samples at codon 90, 6% samples were mutated at codon 91 and 24% were mutated at codon 94.
An analysis of oil price volatility using var: evidence from Pakistan
(Lahore Journal of Business, 2015) Abdul Rafay; Saqib Farid
Oil is a crucial economic input and Pakistan’s growth, production levels, and price levels are affected significantly by oil price volatility. This paper captures the impact of oil price shocks on Pakistan’s economy by considering variables such as gross domestic product, the wholesale price index, and large-scale manufacturing index. Our analysis is based on vector autoregression and the results are in line with similar studies. We also determine the precise short-term or long-term impact of oil price volatility on the relevant variables.
Analysis of stability and accuracy for forward time centered space approximation by using modified equation
(Science International, 2015) Tahir Ch; N.A. Shahid; M.F. Tabassum; A. Sana; S.Nazir
In this paper we investigate the quantitative behavior of a wide range of numerical methods for solving linear partial differential equations [PDE’s]. In order to study the properties of the numerical solutions, such as accuracy, consistency, and stability, we use the method of modified equation, which is an effective approach.To determine the necessary and sufficient conditions for computing the stability, we use a truncated version of modified equation which helps us in a better way to look into the nature of dispersive as well as dissipative errors. The heat equation with Drichlet Boundary Conditions can serve as a model for heat conduction, soil consolidation, ground water flow etc.Accuracy and Stability of Forward Time Centered Space (FTCS) scheme is checked by using Modified Differential Equation [MDE].

Workforce diversity and employees commitment in the context of Globalization has attained significant attention of today’s Researchers. This paper endeavors to ascertain major factors of work-setting and its effects on organizational performance. Two independent variables i.e workforce diversity and committed workforce relations have been analyzed on employee’s organizational performance. Data was collected from 286 respondents from employee’s belonging to the corporate sector of Islamabad Pakistan. Middle level management tiers were segment of the study age ranging from 30 to 40 years. Questionnaire was administered using five point likert scale. Result revels that there is 71% variation between committed work force and organizational performance: henceforth, that committed work force is an important factor of organizational growth with a t-value of (17.295). The p-value values indicates that the variables are significant as P<.05. Similarly, committed work force effects have variation on organizational performance by 20 %. The results further represent that the variables are significant with the p-value of <.05). It is evident from the analysis that diverse workforce once managed well on the work environment and employee’s are committed then organizational performance is with t-value of 6.679. It is therefore imperative for the organizations to accord due priority to the major work-setting like diversity and employee commitment in the organizations facilitating employees to yield befitting organizational loyalty.

Analytic solutions of oldyrod-b fluid with fractional derivatives in a circular duct that applies a constant couple
(Alexendria Engineering Journal, Elsevier, 2016) Muhammad Bilal Riaz; Muhammad Imran Asjad
The aim of this article was to analyze the rotational flow of an Oldroyd-B fluid with fractional derivatives, induced by an infinite circular cylinder that applies a constant couple to the fluid. Such kind of problem in the settings of fractional derivatives has not been found in the literature. The solutions are based on an important remark regarding the governing equation for the nontrivial shear stress. The solutions that have been obtained satisfy all imposed initial and boundary conditions and can easily be reduced to the similar solutions corresponding to ordinary Oldroyd-B, fractional/ordinary Maxwell, fractional/ordinary second-grade, and Newtonian fluids performing the same motion. The obtained results are expressed in terms of Newtonian and non-Newtonian contributions. Finally, the influence of fractional parameters on the velocity, shear stress and a comparison between generalized and ordinary fluids is graphically underlined.
