Cointegration and Error-Correction Modelling of Wheat Consumption in Pakistan

The estimated long and short-run elasticities suggest that income is the most significant determinant of wheat consumption in the long run while price of wheat is the major affecting factor of wheat consumption only in the short run. The less elastic nature of wheat demand both in the short and the long run suggests that under the likely Doha Round agricultural trade liberalization, wheat price rise will harm the poor consumers

Although the prevalence of HIV/AIDS seems to be low but still the country is at high risk as the potential for a widespread epidemic is high due to contamination risk factors common in this country like other countries with high HIV prevalence. These risk factors include, low literacy, poverty, high fertility, low contraception uptake and poor access to health and education. This current review establishes the presence of HIV among all four provinces of Pakistan and further necessitates detailed behavioral study for risk assessment in subpopulation. The society in general needs to debate the issues through conferences, seminars, workshops and media for enhancing awareness.

Numerous previous approaches aimed at balancing the consumption of energy in wireless networks are either too

Organizational Culture and Its Impact on the Job Satisfaction of the University Teachers of Lahore

Lack of existence of supportive organizational culture in education sector may be one of the important reasons of this. Supportive organizational culture may raise the level of job satisfaction of teachers and satisfied teachers may produce healthy, satisfied and creative minds. Present study aims to determine the effect of organizational culture on job satisfaction level of teachers of public and private sector higher education institutes and universities of Lahore which is second largest city of Pakistan and a hub of higher education. Data were collected from a sample of 347 teachers through structured questionnaire. Principal Component Analysis was employed to test the construct validity. Regression analysis was conducted to determine the effect of organizational culture on job satisfaction of teachers. Empirical findings show that organizational culture is categorized into two components i.e. organizational culture related to managers and leaders (OCM) and organizational culture related to employees (OCE). In this study effect of both kinds of culture on job satisfaction is positive and significant. However, we observe that effect of OCE on job satisfaction is higher than effect of OCM.

Molecular characterisation and infectivity of a “Legumovirus” (genus Begomovirus : family Geminiviridae ) infecting the leguminous weed Rhynchosia minima in Pakistan

Virus Research, Sep 1, 2009

All previously identified LYMVs were isolated from leguminous crop species. Here we have identified a virus related to the LYMVs in a common weed, the legume Rhynchosia minima originating from Pakistan. Analysis of the sequence of the virus shows it to be a typical bipartite begomovirus. Sequence comparisons to all other begomovirus sequences available in the databases show the virus from R. minima to be distinct, with the highest level of sequence identity (69.5%) to an isolate of Mungbean yellow mosaic virus. This indicates that the virus identified here is a new species in the genus Begomovirus for which we propose the name Rhynchosia yellow mosaic virus (RhYMV). By Agrobacterium-mediated inoculation we show that, in common with the other LYMVs, the clones of RhYMV are not infectious to the experimental host Nicotiana benthamiana. In soybean, the results of inoculation depended upon the variety. In soybean var. Ig6 the symptoms were mild and plants recovered from infection. However, in var. FS-85, symptoms were severe and progressed to necrosis, indicative of a hypersensitive response. These results indicate that there is resistance to RhYMV in the soybean germplasm. The significance of these results is discussed.

The accurate prediction of new collaborations between members of a collaboration network can help accelerate the realization of new synergies, foster innovation, and raise productivity. For this study, the authors collected a large data set of publications from 630 conferences of the IEEE and ACM of more than 257, 000 authors, 61, 000 papers, capturing more than 818, 000 collaborations spanning a period of 10 years. The data set is rich in semantic data that allows exploration of many features that were not considered in previous approaches. We considered a comprehensive set of 98 features, and after processing identified eight features as significant. Most significantly, we identified two new features as most significant predictors of future collaborations; 1) the number of common title words, and 2) number of common references in two authors' papers. The link prediction problem is formulated as a binary classification problem, and three different supervised learning algorithms are evaluated, i.e. Naïve Bayes, C4.5 decision tree and Support Vector Machines. Extensive efforts are made to ensure complete spatial isolation of information used in training and test instances, which to the authors' best knowledge is unprecedented. Results were validated using a modified form of the classic 10-fold cross validation (the change was necessitated by the way training, and test instances were separated). The Support Vector Machine classifier performed the best among tested approaches, and correctly classified on average more than 80% of test instances and had a receiver operating curve (ROC) area of greater than 0.80.

Investigating the potential role of platelet derived growth factor (PDGF)

It switches on a plethora of molecules other than its classical pathway. It is engaged in various transitions of development however if the unleashed potentials lead astray it brings forth tumorigenesis. Conventionally, it has been assumed that the components of this signaling pathway show fidelity and act with a high degree of autonomy. However, as illustrated by the PDGF signal transduction, reinterpretation of recent data suggests that machinery is often shared between multiple pathways and other components crosstalk to each other through multiple mechanisms. There is a very indiscriminate line that demarcates between normal division and neoplasia. A number of unidentified proteins might be instrumental to this transition. The signal perpetuation is a remarkable portfolio of tumor progression.

These skills, knowledge and learning are carried out in the educational institutes or universities through experts teaching professionals. The education system of Pakistan is divided into five basic levels which include: primary school, secondary school, higher secondary school, college, and university level. The basic aim of this study is to investigate the education perspective and comparison in different areas of Khyber Pakhtunkhwa (K.P.) for the students who are studying at the University of Peshawar. This study finds the ratio of male and female students who are currently enrolled in various departments of the university. This ratio is plotted in the map of Khyber Pakhtunkhwa. The proposed study highlights the comparison of the students' in undergraduate programme only.
