Agrometeorological wheat yield prediction in rainfed Potohar region of Pakistan  [PDF]
Dildar Hussain Kazmi, Ghulam Rasul
Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.32019
Abstract: The reliable early estimates of production had always been the prime concerns of growers on one hand and planners as well as policy makers for import/export on the other hand. This study represents a linear regression model making use of meteorological parameters at critical stages of crop’s life cycle to predict the wheat yield about two months earlier than the harvesting. A statistical based software “Statistical Package for Social Sciences” (SPSS) and MS-excel were employed as working tools. Decadal (ten days) agrometeorological data for Rabi season (for the period 1993-2011) being observed at Regional Agromet Centre, Rawalpindi have been utilized. The parameters studied for correlation were mainly rainfall (amount and days), air temperature (minimum, maximum, mean), heat units (on phenological basis), relative humidity, wind speed, sunshine duration, reference crop evapotran-spiration etc. Finally, minimum temperature, sunshine duration and rainfall amount in January (tillering and stem extension phase) proved to be the reliable predictors for the final yield. The correlation coefficients for these parameters on individual basis resulted within the acceptable range where as in aggregate it remained 0.87, an optimistic value.
Comparative Study for ECHAM5 and SDSM in Downscaling Temperature for a Geo-Climatically Diversified Region, Pakistan  [PDF]
Dildar Hussain Kazmi, Ghulam Rasul, Jianping Li, Suhail Babar Cheema
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.51016
Abstract:

Pakistan is a country with diversified features in terms of geography and climate. It is an agriculture based country, mainly dependent on Indus water system. In Pakistan, there are loftyplateaus to the north and Arabian Sea in the south, while the interior portion is covered with plateaus or agriculture plains. For such a region, any attempt to monitor/analyze climatic data requires some more specific details. A statistical software SDSM is utilized for downscaling daily temperature data of Pakistan and the results generated are compared with the output of a recommended model “ECHAM5”. After analysis, it revealed that comparatively SDSM produced much better results. The outputs from both the approaches were correlated with the observed data; SDSM-observed gave values for correlation coefficient R2 in the range of 81% - 94% whereas ECHAM5-observed produced 73% - 87% for different meteorological stations of Pakistan. On the basis of this study, SDSM can be recommended for future scenario generation of temperature data of Pakistan as well.

Impact of climate change on agriculture during winter season over Pakistan  [PDF]
Khalid M. Malik, Arif Mahmood, Dildar Hussain Kazmi, Jan Muhammad Khan
Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.38122
Abstract: This study has been carried out to investigate the impact of climate change over Pakistan and its surrounding areas (60° - 80°E and 20°- 40° N) during winter seasons (December-February). Variability in three meteorological parameters such as: rainfall; air temperature; and moisture transport, has been investigated. Global Pre- cipitation Climatology Center (GPCC) data for precipitation and National Centre for Environ- mental Prediction (NCEP) reanalysis data for computation of Moisture Flux Convergence (MFC) and temperature have been used for the period of 49 years (1961 to 2009). The study period has been divided into three phases on basis of pre- cipitation anomaly i.e., before climate change scenario (1961-1985), transition period (1986- 1999) and after climate change scenario (2000- 2009).Variability in precipitation has been ob- served in three different ways such as, slightly increase in magnitudes, decrease in rainy days and shifting of precipitation pattern towards south of the country. Moisture transport from the surrounding has decreased with increase in precipitation which is indirectly associated with decreases in mass deposit on the glaciers. In- crease in temperature is more prominent over upper and lower part as compared to the central parts of the country. Uncertainty in precipitation has also been observed. Shift of precipitation over southern parts showed positive impact over agriculture sector. As a result, Rabi crop yield has increased during last decade over southern parts of the country.
STATISTICAL ANALYSIS OF THE TM- MODEL VIA BAYESIAN APPROACH
Muhammad Aslam,Dildar Hussain,Ghausia Masood Gilani
Pakistan Journal of Statistics and Operation Research , 2012, DOI: 10.1234/pjsor.v8i4.174
Abstract: The method of paired comparisons calls for the comparison of treatments presented in pairs to judges who prefer the better one based on their sensory evaluations. Thurstone (1927) and Mosteller (1951) employ the method of maximum likelihood to estimate the parameters of the Thurstone-Mosteller model for the paired comparisons. A Bayesian analysis of the said model using the non-informative reference (Jeffreys) prior is presented in this study. The posterior estimates (means and joint modes) of the parameters and the posterior probabilities comparing the two parameters are obtained for the analysis. The predictive probabilities that one treatment (Ti) in preferred to any other treatment (Tj) in a future single comparison are also computed. In addition, the graphs of the marginal posterior distributions of the individual parameter are drawn. The appropriateness of the model is also tested using the Chi-Square test statistic.
Monetary Policy Reaction Function in Open Economy Version: Empirical Evidence in Case of Pakistan
Sulaiman D Muhammad,Adnan Hussain,Muhammad Ahsanuddin,Shazia Kazmi
Asian Social Science , 2012, DOI: 10.5539/ass.v8n8p89
Abstract: Aftermath the globalization and financial liberalization the purpose of monetary policy deviates from economic growth to economic stabilization. Therefore monetary authority adjusts its policy rate in response to systematic changes in macroeconomic activities and business fluctuations. The rule which is followed to stable an economy at development path is called Taylor’s rule. This study empirically investigates monetary policy reaction function in case of Pakistan by applying Taylor’s rule (1993) nevertheless Johansan co integration test is employed for its open economy version. The monthly data from the period of January 2003 to December 2008 has been collected for the analysis. It is found that the coefficient of output gap and exchange rate gap are significant while coefficient of inflation gap is insignificant. The results depicted that inflation does not play significant role due to the monetary policy as such in the frame work of Pakistan’s economy. Therefore inflation targeted monetary policy does not suggest for Pakistan. To analyze the stability of coefficient ROLLING WINDOW technique was employed as it is found that monetary authority adopted inflation targeted monetary policy after 2002 which was not suitable as this study has shown.
Zinc Requirement of Barani Wheat
Zahid Pervaiz,Khadim Hussain,S.S.H.Kazmi,Mrs. Belqees Akhter
Asian Journal of Plant Sciences , 2003,
Abstract: Zinc requirement of barani wheat was investigated through a farmer field experiment near Jhelum in Rawalpindi division during 1999-2000. The Zn levels (Kg ha-1) tried were 0, 2.5, 5.0, 7.5 and 10.0. The data revealed that wheat crop responded significantly to added zinc and 7.5 Kg Zn ha-1 appeared to be the optimum dose for conditioning barani wheat yield under experimental condition. The agronomic efficiency [Straw nutrient ratio/ Grain nutrient ratio (SNR/GNR)] reduced with subsequent increase in Zn application level. More research is needed to authenticate the Zn requirement of barani wheat.

Chang-Ming Guo, Rong-Rong Chen, Dildar Hussain Kalhoro, Zhao-Fei Wang, Guang-Jin Liu, Cheng-Ping Lu, Yong-Jie Liu
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0087980
Abstract: Streptococcus agalactiae, long recognized as a mammalian pathogen, is an emerging concern with regard to fish. In this study, we used a mouse model and in vitro cell infection to evaluate the pathogenetic characteristics of S. agalactiae GD201008-001, isolated from tilapia in China. This bacterium was found to be highly virulent and capable of inducing brain damage by migrating into the brain by crossing the blood–brain barrier (BBB). The phagocytosis assays indicated that this bacterium could be internalized by murine macrophages and survive intracellularly for more than 24 h, inducing injury to macrophages. Further, selective capture of transcribed sequences (SCOTS) was used to investigate microbial gene expression associated with intracellular survival. This positive cDNA selection technique identified 60 distinct genes that could be characterized into 6 functional categories. More than 50% of the differentially expressed genes were involved in metabolic adaptation. Some genes have previously been described as associated with virulence in other bacteria, and four showed no significant similarities to any other previously described genes. This study constitutes the first step in further gene expression analyses that will lead to a better understanding of the molecular mechanisms used by S. agalactiae to survive in macrophages and to cross the BBB.

Academic Research International , 2012,
Abstract: The current qualitative study explored the nature of elder abuse in District Gujrat. The study aimed to determine the socio-demographic characteristics of elderly as well as the type of elder abuse. Purposive sampling was used to approach 13 respondents (elderly males and females). Their age was 60 and above. Semi-structured in-depth interviews were conducted to collect the data. An interview guide was used for semi-structured interview which was prepared afterliterature review and theories of violence. Thematic analysis was done through all transcribed data of interviews. Major themes emerged psychological abuse and financial abuse. However, presence of neglect and physical abuse has also been found. The findings showed that most of the respondents who had faced one type of abuse had faced other form of abuse too. Findings are the contributing source in community awareness programs.

Syeda Asiya Zenab Kazmi, Marja Naaranoja
Open Journal of Leadership (OJL) , 2013, DOI: 10.4236/ojl.2013.24010
Abstract:

The study offers grounds to measure level of “creativity” through directional “leadership management options” (i.e. transactional leadership, laissez-faire leadership) in teams marked by individual differences or diversity. The study results confirmed that transformational leadership provides support to generate creativity by even the ordinary performers marked by the workforce diversity phenomenon among the organizational workers.
