مولوی مظہر الحق

مولوی مظہرالحق صاحب پٹنہ
جس طرح ہمارا پرانا سال ایک بڑے قومی حادثہ یعنی پرانی تعلیم کے ایک بہترین نمونہ (مولانا حبیب الرحمان عثمانی دیوبندی) کے دائمی فقدان پر ختم ہوا، اسی طرح ہمارے نئے سال کا آغاز بھی ایک بڑے قومی حادثہ یعنی نئی تعلیم کے ایک بہترین نمونہ (مولوی مظہرالحق صاحب بیرسٹر پٹنہ) کی دائمی جدائی سے ہوا، مولوی مظہرالحق صاحب مرحوم کی قومی و سیاسی حیثیت تو الگ ہے، ان کی اخلاقی اور علمی حیثیت بھی کچھ کم قابل ذکر نہیں ہے، وہ فارسی سے واقف، عربی سے آشنا، انگریزی کے ادیب و خطیب اور فلسفہ کے نہایت دقیقہ رس طالبعلم تھے، ان کے علمی کارناموں کا آغاز طوفان نوح کی بحث سے ہوا، الپنچ پٹنہ اور وقت گورکھپور ان کے ابتدائی علمی مباحث کے جولان گاہ تھے، ان کی سب سے آخری علمی تحریر غالباً وہ ہے جو ابھی ابھی پونہ سے شائع ہونے والی انگریزی کی کتاب تصوف و روحانیت پر مقدمہ ہے، وہ نسباً فاروقی تھے، اس لئے ان کی اخلاقی قوت و جرأت کیا سلطنت اور کیا قوم دونوں کے مقابلہ میں برابر تھی، وہ جس کو حق سمجھتے تھے اس کے اظہار میں نہ ان کو سلطنت کی پروا ہوتی تھی اور نہ قوم کی، ان کا یوروپین طرز معاشرت کو الوداع کہہ کر وفعتہ مشرقی اور غالی مشرقی بن جانا ان کی بے مثال اخلاقی جرأت کا نمونہ ہے، مرحوم کی آخری عمر روح و روحانیت کی تحقیق میں صرف ہوئی، خدا ان کی روح کو اپنی مغفرت کی لازوال دولت سے مالا مال کرے، اب وہ وہاں پہنچ چکی ہے، جہاں کے کشف زار کے لئے وہ بے قرار تھی۔ (سید سلیمان ندوی، جنوری ۱۹۳۰ء)

 

Mitogen Activated Protein Kinase: Function and Responses to Different Stresses in Plants

Mitogen Activated Protein Kinase (MAPK) pathway is the most commonly studied signaling mechanisms, consisting of different groups of protein kinases that participate in regularly connecting interpretation of external stimuli that can change in gene expression or cellular organization within eukaryotic systems. The MAP kinase pathways functions in plants cell signaling (intra- and extra). MAPK cascades follow a response system. MAP kinases are the component of kinase constituents that deliver signals from sensors to responders in eukaryotes including plants. Several pathways are activated under different environmental stresses. Stimulating agents may be biological (biotic) like microbial infections or environmental (abiotic) like temperatures threshold, high salt concentration, drought, heavy metal, Ultra-violet radiation, ozone gases and reactive oxygen species (ROS). The involvement of MAPK signaling pathway in different stresses has been widely studied. In this review we also try to highlight MAPK cascades, its regulation, functions and recent findings in various cellular processes against stress conditions.

Decline of Public Schools in Punjab and Strategies for Their Revival

The government of Pakistan has legal bindings and international commitments to provide education to its each and every citizen irrespective of gender, caste, creed, and race. Public school system in Pakistan works under the auspices of federal, provincial, and district governments, and offer education to masses. There are sufficient empirical evidences to support the idea that public schools have been experiencing a declining trend on different indicators like quality of students’ learning and outputs, enrolments of students, and parent dissatisfaction, etc. During discussions with experts and informed stakeholders, it was identified that public schools in Punjab are declining due to some social, governmental, and school related problems. This study was held to investigate the in-school factors which resulted decline of public schools in Punjab. The main objective of the study was to identify school-related problems of public schools in Punjab (Pakistan) and then propose strategies for the revival of these schools. Four main stakeholders of schooling i.e. the head teachers, teachers, parents, and students made the population of the study. Multi-stage sampling technique was used to select the sample from the population. To select a representative sample, 36 districts of Punjab were distributed in three strata on the basis of their educational indicators and two districts from each stratum were selected randomly. In the next stage, one tehsil from each district was randomly selected. Six secondary or higher secondary schools were conveniently selected from each tehsil to select the respondents for the study. In this way, the valid responses of 36 head teachers, 263 teachers, 282 parents, and 802 students from public schools were received for the study. A semi-structured interview protocol regarding school governance and management was developed for the head teachers; a job satisfaction scale was adapted for the teachers; a structured interview was developed to measure parents’ satisfaction with public schools; and school learning environment scale was developed for students of public schools. The research instruments were validated by experts and then pilot tested. The study found that the schools faced scarcity of funds to improve teaching learning process. Furthermore, the head teachers had no real administrative authority and their too heavy administrative duties were detrimental to their role as instructional leader. The head teachers were not satisfied with their promotion policy, monitoring and accountability mechanism, working relationship with district administration, and the competency building trainings. The teachers also showed their dissatisfaction with their service structure and working environment of the public schools. The parents were not satisfied with the quality of teaching and role of schools in overall personality development of their children. The students, parents, and head teachers agreed that there was lack of communication between school and parents. Furthermore, almost all of them agreed that physical and learning facilities were available but not properly utilized. On the basis of the findings of the study, strategies were suggested to revive public schools in Punjab (Pakistan). The major suggestion in the proposed strategies focus on increasing budget for schools, financial and administrative empowerment of head teachers, changes in service structure of head teachers and teachers, improve quality of teaching, effective utilization of physical and learning resources, communication between school and parents, and activate community participation.
