Tax Shield and Its Impact on Corporate Dividend Policy: Evidence from Pakistani Stock Market  [PDF]
Akhlaq ul Hassan, Mubashar Tanveer, Muhammad Siddique, Muhammad Mudasar
iBusiness (IB) , 2013, DOI: 10.4236/ib.2013.54023
Abstract:

The problem: what is the taxation impact on dividend policy? While much optimal taxation research focuses on the economic effects of taxation, the purpose of this study is to add a new dimension by investigating the relationship between taxation and payout ratio and some other variables of dividend policy. These relations are tested using the data from financial statements of KSE listed companies. The results show that tax shield has no significant relation to the dividend payout ratio but mostly dividend policy is due to the size of the firm and its profitability.

Reliability and Validity of Qualitative and Operational Research Paradigm
Muhammad Bashir,Muhammad Tanveer Afzal,Muhammad Azeem
Pakistan Journal of Statistics and Operation Research , 2008, DOI: 10.1234/pjsor.v4i1.59
Abstract: Both qualitative and quantitative paradigms try to find the same result; the truth. Qualitative studies are tools used in understanding and describing the world of human experience. Since we maintain our humanity throughout the research process, it is largely impossible to escape the subjective experience, even for the most experienced of researchers. Reliability and Validity are the issue that has been described in great deal by advocates of quantitative researchers. The validity and the norms of rigor that are applied to quantitative research are not entirely applicable to qualitative research. Validity in qualitative research means the extent to which the data is plausible, credible and trustworthy; and thus can be defended when challenged. Reliability and validity remain appropriate concepts for attaining rigor in qualitative research. Qualitative researchers have to salvage responsibility for reliability and validity by implementing verification strategies integral and self-correcting during the conduct of inquiry itself. This ensures the attainment of rigor using strategies inherent within each qualitative design, and moves the responsibility for incorporating and maintaining reliability and validity from external reviewers’ judgments to the investigators themselves. There have different opinions on validity with some suggesting that the concepts of validity is incompatible with qualitative research and should be abandoned while others argue efforts should be made to ensure validity so as to lend credibility to the results. This paper is an attempt to clarify the meaning and use of reliability and validity in the qualitative research paradigm.
The Inverted Double Heterojunction Organic Photovoltaic Devices using Electrospun TiO2 Nanofibers
Muhammad Tanveer,Amir Habib,Muhammad Bilal Khan
International Journal of Soft Computing & Engineering , 2013,
Abstract: The introduction of electrospun TiO2 nanofibershas improved the performance of inverted poly (3-hexylthiophene) (P3HT) and (6, 6)- phenyl-C61- butyric acidmethyl ester (PCBM) solar cells by providing efficient chargegeneration and collection through double heterojunction.Electrospun TiO2 nanofibers increased the charge separation andcollecting capability of the devices both from P3HT and PCBM byproviding interfaces between P3HT-TiO2 and PCBM-TiO2nanofibers. The resulting devices have reached to maximumpower conversion efficiency (PCE) of 4.25±0.03% contributed byincreased short circuit current (Jsc).
BAYESIAN INFERENCE FOR THE PARAMETER OF THE POWER DISTRIBUTION
Tanveer Kifayat,Muhammad Aslam,Sajid Ali
Journal of Reliability and Statistical Studies , 2012,
Abstract: This study provides Bayesian analysis of the power model using two informative(gamma and Rayleigh) priors and two non-informative (Jeffreys and uniform) priors. The priorpredictive distribution is used to elicit the values of the hyperparameters of the prior distribution.The priors are compared using Bayes point and interval estimates, posterior variances,coefficients of skewness and coefficients of kurtosis. Bayes factors and Bayes posterior risks arealso used for the comparison of informative and non-informative priors.
Effect of Different Levels of Nitrogen and Harvesting Times on the Growth, Yield and Quality of Sorghum Fodder
Muhammad Ayub,Muhammad Ather Nadeem,Asif Tanveer,Azhar Husnain
Asian Journal of Plant Sciences , 2002,
Abstract: In a field trail at Faisalabad, fodder yield and quality of sorghum (Sorghum bicolor L.) cultivar JS-263 as influenced by different nitrogen levels (0, 50, 100 and 150 kg ha -1) and harvesting times (45, 60 and 75 days after sowing) was studied in 2000. Both green and dry matter yields were increased with increasing nitrogen levels and delaying harvest. The increase in yield was mainly due to higher plant height, stem diameter and number of leaves plant -1. The contents of crude protein, ether extractable fat and ash were increased with increased nitrogen levels and decreased with delaying the harvest. Whereas, neutral and acid detergent fiber were increased by delaying the harvest and decreased by the nitrogen application. Based on these finding, the nitrogen level of 150 kg ha -1 and harvesting time 75 days after sowing was found better combination for getting higher yields of sorghum cultivar JS-263 under Faisalabad conditions.
Competition Functions of Different Canola-Based Intercropping Systems
Muhammad Tahir,Muhammad Asghar Malik,Asif Tanveer,Rashid Ahmad
Asian Journal of Plant Sciences , 2003,
Abstract: Competition functions of different intercropping systems i.e. canola, wheat gram, lentil and linseed were compared with sole cropping of canola for two consecutive years under the field conditions. Competition behaviour of component crops across different intercropping systems and planting patterns was determined in terms of relative crowding coefficient, aggressivity and competitive ratio. Relative crowding coefficient (RCC) reflected that maximum K (4.08) was obtained from canola+one row of wheat intercropping system. Aggressivity (A) values ?0.03 and 0.06 indicated that wheat was the most competitive crop to canola. Similarly, competitive ratio (CR) 0.82 and 0.51 showed that among intercrops, wheat proved to be a better competitor than other intercrops when grown in association with canola.
Agro-economic Advantages of Different Canola-based Intercropping Systems
Muhammad Tahir,Muhammad Asghar Malik,Asif Tanveer,Rashid Ahmad
Journal of Agronomy , 2003,
Abstract: Agro-economic advantages of different intercropping systems i.e. canola+one row of wheat, canola+two rows of wheat, canola+one row of gram, canola+two rows of gram, canola+one row of lentil, canola+two rows of lentil, canola+one row of linseed and canola+two rows of linseed were compared with sole cropping of canola for two consecutive years under field conditions. Canola seed yield equivalent, land equivalent ratio, area-time equivalent ratio and net income values of canola+one row of wheat intercropping system was higher than the other intercropping systems and sole cropping of canola.
A Hybrid Method for Edge Continuity Based on Pixel Neighbors Pattern Analysis (PNPA) for Remote Sensing Satellite Images  [PDF]
Waqas Haider, Muhammad Sharif Malik, Mudassar Raza, Abdul Wahab, Izhar Ahmed Khan, Umar Zia, Jawad Tanveer, Hadia Bashir
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2012, DOI: 10.4236/ijcns.2012.529072
Abstract: Edge enhancement is derived from lack of accurate result from edge detection techniques. The image which is captured from long distances carries a lot of noise and blur which causes edge discontinuity. Although some novel algorithms which are based on cellular neural network, fuzzy enhancement and binary morphology have shown accuracy in order to obtain refined edge but still the problem of edge discontinuity arises. Eliminating discontinuity of edge a hybrid technique is proposed based on pixel neighbors pattern analysis PNPA. In the technique Canny operator for initial edge detection, PNPA operation for edge enhancement are performed for remote sensing satellite image successively. The visual and subjective evaluation shows that the proposed PNPA operation can effectively eliminate the influence of edge discontinuity which occurred due to noise and blurr in original captured image, as comparing to existing edge segmenting processes.

Hafiz Muhammad Tahir, Kishwar Hussain, Azhar Abbas Khan, Sajida Naseem, Hamza Tanveer Malik, Abida Butt, Rabia Yaqoob
Open Journal of Animal Sciences (OJAS) , 2013, DOI: 10.4236/ojas.2013.34A1001
Abstract: The present study was designed to evaluate the susceptibility of Culex quinquefasciatuns against malathion in Sargodha district of Pakistan. The activities of detoxifying enzymes i.e., β-esterases, GSTs and monooxygenases were also estimated. Our results revealed 100 percent mortality in insecticide treated groups after 24 hours of exposure. There was no difference in the activities of insecticide detoxifying enzymes between control and treated groups. We concluded from our work that malathion is still effective against C. quinquefasciatuns in the area for control of mosquito population.
Antimicrobial Characteristics of Untreated Wood: Towards a Hygienic Environment  [PDF]
Muhammad Tanveer Munir, Hélène Pailhories, Matthieu Eveillard, Florence Aviat, Didier Lepelletier, Christophe Belloncle, Michel Federighi
Health (Health) , 2019, DOI: 10.4236/health.2019.112014
Abstract: Wood, as a contact surface, has been used for centuries but is usually questioned because of its porosity and organic composition. It has natural antimicrobial properties and, hygienically, can stand the comparison with other materials such as plastic, glass and steel. In this review, we focused on potential microbe-inhibiting properties of wooden surfaces being used in hygienically important places like health institutes and food industries. This article addresses the questionable properties of untreated wood like hygroscopicity, porosity, roughness and chemical composition, and their relation to the hygienic and antimicrobial nature of this material. The other factors linked to the hygienic properties of wood, such as age, species and type of wood, have also been discussed. Our analysis of literature will create better understanding for acceptance of wood as a safety renewable resource. It also provides an outline for future research considering wood material in critical healthcare or food industries.
