The application of municipal solid waste compost (MSWC) is rapidly becoming popular worldwide to enhance and sustain soil organic matter (SOM) and crop productivity. The use of municipal solid waste as compost also offers a unique opportunity for its economical disposal. Factually, this disposal prospect is even more important than upraise of soil fertility and crop yields, especially in developing countries like Pakistan where management of solid waste is a major environmental issue. Despite of its potential as nutrient source, widespread acceptability of MSWC has suffered due to the presence of heavy metals and possible risk to human being through food chain. Furthermore, the sole use of MSWC to satisfy nutrients need of a crop is not a practical approach and may result into heavy metals and phosphorus (P) accumulation in soil. Elevated P levels pose serious environmental risk such as eutrophication. To alleviate risks of heavy metals and phosphorus accumulation in soil, an integrated nutrient management scheme mounting to the combined use of MSWC and mineral fertilizers is needed. To develop a practically viable, economically feasible and environmentally safe nutrient management plan for rice-wheat and cotton- wheat cropping systems in a region of Punjab province of Pakistan, two 3-year (2002-05) field trials were conducted on a permanent layout with six different treatments comprising three management strategies and two nutrient doses. Management strategies included the application of mineral fertilizer as the sole nutrient supplement and the application of mineral fertilizer in combination with MSWC with and without pesticide/herbicide treatments. Within each management strategy, nutrients were applied in two different doses. One dose was based on standard N, P and K recommendations without site specific analysis of soil nutrient levels. For the second dose, the applied fertilizer amount was calculated based on measured, site specific, plant available soil phosphorus levels. Results revealed that an integrated application of MSWC and mineral fertilizer based on site specific phosphorus levels with the use of pesticides and herbicides was an economically viable and environmentally safe option in comparison with general practice of sole mineral fertilizer applications. The application of MSWC also led to the improvement (statistically significant) of physical properties of soil in terms of reduction in soil bulk density and ii penetration resistance. Soil organic matter contents were found to be sustainable over 3- year trial period and almost no significant increase and decrease in SOM was observed. Measured, site specific, plant available soil phosphorus level for surface (0-15 cm) soil was significantly higher as compared to initial status in both cropping systems for all treatments by the end of trial and was near to the target sufficiency levels. Phosphorus accumulations, important from environmental point of view, were also not observed. No potential risk of heavy metals (Zn, Cd, Cr, Pb, Ni) accumulation was ascertained. On the basis of experimental results, a combined use of MSWC and chemical fertilizer can be recommended to the farmers to reap its benefits in terms of improvement in SOM content and physical properties of soil. Consequently, higher crop yield.

مولانا محمد اسحاق سنبھلی

مولانا محمد اسحاق سبنھلی
۷؍ جنوری کو مولانا اسحاق سبنھلی کی رحلت ہوگئی، وہ ایک عالم دین، جنگ آزادی کے مجاہد جمعیۃ علمائے ہند اور ہندوستانی کمیونسٹ پارٹی کے سرگرم رکن تھے اور برسوں ریاستی قانون ساز کونسل اور پارلیمنٹ کے ممبر بھی رہے۔
مولانا کی زندگی جہد و جہاد سے عبارت تھی، عوام کی خدمت ان کا نصب العین تھا، لوگوں کا کام کرکے خوش ہوتے تھے، بڑے خلیق اور ملنسار تھے۔
آزادی سے پہلے انہوں نے استخلاص وطن کے لیے قربانی دی اور آزادی کے بعد فرقہ پرستوں اور رجعت پسندی کے خلاف صف آرا رہے، ان کی ریشہ دوانیوں اور سازشوں کو بے نقاب کیا، مولانا کی زندگی اقلیتوں کے حقوق کی بازیابی کے لئے جدوجہد اور سیکولرازم، انصاف اور جمہوریت کا پرچم بلند کرنے میں بسر ہوئی۔ وہ حب الوطنی کے جذبہ سے سرشار تھے، جس طرح جمعیۃ علماء کے زیر قیادت مسلمانوں کی فلاح و بہود کے کام میں حصہ لیتے تھے، اسی طرح وطن عزیز کی سالمیت اور استحکام کے لیے بھی ہمیشہ ساعی رہتے۔
مولانا اردو تحریک کے قائدین میں تھے، اس کے خلاف ہونے والی زیادتیوں اور ناانصافیوں کے خلاف ہمیشہ لڑتے رہے۔ عرصہ تک ریاستی انجمن کے جنرل سکریٹری تھے۔
مولانا اسحاق سنبھلی دارالمصنفین کے کاموں کے بڑے قدرداں تھے، چند برس پہلے اپنی پارٹی کے کام سے اس نواح میں آئے تو وقت نکال کر یہاں بھی تشریف لائے اور دارالمصفین کے تمام شعبوں کو دیکھ کر اپنی مسرت ظاہر کی۔
موجودہ لیڈروں اور قومی کارکنوں کی طرح ان میں مصلحت پسندی اور نام و نمود کی ہوس نہ تھی، جس بات کو صحیح سمجھتے تھے اسے بے دھڑک کہہ دیتے تھے، افسوس ہے کہ ملک سے ایسے مخلص، بے غرض، جرأت و ہمت والے اور نام و نمود سے بے زار لیڈر ایک ایک کر کے...

TELETHERAPY- AN INNOVATIVE WAY OF TREATMENT IN THE FIELD OF OCCUPAIONAL THERAPY IN PAKISTAN

Teletherapy is an emerging and enlarging tool for having treatment in occupational therapy in rehabilitation sciences among occupational therapists all over the world mainly in Pakistan, especially during the era of COVID-19. A lot of studies have been done already highlighting the paramount of teletherapy around the world but it is a new rising mode of treatment in Pakistan coming to light. Therapists and Patients throughout the country making the most of this treatment way respectively and hence this method of treatment while using of technologies is highly being appreciated. The aim of this study is to foster and encourage the use of this technology in third-world countries like Pakistan. It is the most used treatment tool during COVID-19 among occupational therapists all over the country and is highly appreciated in order to cut-down the negative circumstances of a one-to-one session in which therapist and patient is in highly close contact to each other. This course of action has advocate the on-going rehabilitation treatment and has kept away people from COVID-19 expansion to the most extent. In this study, a 5years old boy was included with an under-diagnostic process within the umbrella term of genetic disorder. Having genetic disorder, his sessions were taken in tele-clinic using video call technology during COVID-19. In this process, AOTA Occupational Therapy Tele-Health Decision Guide, AOTA Occupational Profile Template, AOTA Advisory Opinion for the Ethics Commission Teletherapy, i-PiCS-Internet-Based Parent-Implemented Communication Strategies Program, and modeling strategy were followed.

Financial Reporting Quality, Family Owned Business, and Investment Efficiency

Present study investigates the impact of two monitoring mechanisms; family ownership, and financial reporting quality with other explanatory variables on investment efficiency for the period of 2007 to 2014 for non-financial listed companies at the Karachi Stock Exchange. This study employs two dimensional Pooled Ordinary Least Square Regression, Two Stage Least Square Regression (2SLS), and Generalized Method of Moment (GMM), Feasible Generalized Least Square Regression (FGLS) method to test and examine the significance of hypothesis. The results indicate that higher financial reporting quality and family ownership is associated with higher investment efficiency. Furthermore, the moderation effect of family ownership on the relationship of financial reporting quality and investment efficiency indicate that impact of financial reporting quality on investment efficiency is higher for family owned business as compare to the impact of financial reporting quality on investment efficiency for non-family owned business. The results also show that higher financial reporting quality mitigates the problem of over and under investment as information gap reduces. The results reveal that family ownership increases investment efficiency and may also mitigate the over and under investment problem. The family firms and higher financial reporting quality reduce the tendency of over-investment and under-investment. Therefore, alignment effect outreaches the entrenchment effect as family shareholder and management shares the same vision and have same long-run investment horizon. The desire to shift business to their next generation is possible if family firms invest in efficient projects, therefore, family firms have more efficient investments as compared to non-family firms. Therefore, in emerging market like Pakistan alignment effect, reduced information asymmetry, efficient monitoring, and long term horizon, and the preservation of socioemotional wealth reduce the propensity of under investment in family firms as compared to ii i non-family firms. The results indicate that family firm in Pakistan use accrual based earning management in order to meet their earning targets. In addition, they have lesser propensity to engage in real based earning management as real based earning management is hard to detect for the regulating bodies. In longer run, real based earning management can damage the business, therefore, family firm has lesser engagement in real based earning management in order to maintain their socio-emotional wealth perspective. The family firms report lower abnormal discretionary expanses, abnormal cash flow from operations and lower abnormal production as compare to non-family firms.. The main findings of this study are almost the same by using different estimation techniques and proxies to measure investment efficiency, family ownership and financial reporting quality. The implication that emerges from these results is that financial reporting quality and family ownership act as a corporate governance mechanism tool that enhances the investment efficiency of family firms as compared to nonfamily firms and also mitigate the over and under-investment problem in any family owned business. Thus, the results support the argument presented by the alignment hypothesis of Agency Theory and dynasty succession dimension of Socio-emotional Wealth Theory. Therefore, understanding the quality of these financial reports in family owned business allows investors, regulatory authorities and policy makers to make informed decision.
