This mix-method study aimed to investigate the conception of leadership effectiveness at secondary school level in Sindh Pakistan. The Leadership Challenges, the Impact of existing System Support and Leadership Coping Approaches were thoroughly explored. The population of this study was based on 448 (both male and female from rural and urban areas) heads of secondary schools of 9 districts of Hyderabad directorate of schools. Data were collected through in-depth individual interviews, and then focus group discussions. Thus, box-oriented Sindh Leadership Challenges Survey Questionnaire [SLCSQ-2013] and Impact of System Support and Leadership Coping Approaches Survey Questionnaire [ISSLCASQ-2013) were developed on the basis of initially collected qualitative data. These Questionnaires were then administered to a wide randomly selected stratified sample of 90 subjects of same population to justify the qualitative data. Major findings of this study reveal that school heads are experiencing serious challenges in many areas of their administration: authority and power, district school relationship, instructional leadership practice, financial management, conduct of annual exams, staff union relationship and community relationship. They are highly challenged by bureaucratic and political forces in performing different leadership roles. They face lack of existing system support in face of such challenges. This study also revealed that heads of schools use various Leadership Coping Approaches: documenting, performing teaching role, dealing according to the professional level of the staff, adopting flexibility in authority and power and reconciliatory approach etc to deal with challenges. xiii Keywords: Leadership Challenges, School leaders, Context, System Supporting Strategies, Leadership Coping Approaches (Strategies and Styles)

مرزا سلطان احمد
افسوس ہے کہ اعظم گڑھ کی ممتاز مقبول شخصیت مرزا سلطان احمد صاحب رٹائر ممبر بورڈ آف ریونیو نے طویل علالت کے بعد گزشتہ ۱۷؍ فروری کو انتقال کیا وہ پرانے علیگ اور اپنے زمانہ کے لائق ترین عہدہ داروں میں تھے، اپنی قابلیت سے ڈپٹی کلکٹری سے کلکٹری اور بورڈ کی ممبری تک ترقی کی اور جہاں رہے اپنی دیانتداری اور شرافت سے مقبول و نیک نام رہے، بڑے عہدہ داروں میں ایسے شریف اور خلیق انسان کم دیکھنے میں آئے ہیں، ان کا خمیر ہی اخلاق و شرافت سے گوندھا گیا تھا، ادنی و اعلیٰ ہر شخص کے ساتھ ان کا اخلاق یکساں تھا، ہر ملنے والے کے ساتھ کوئی نہ کوئی ایسی خصوصیت ضرور برتتے تھے جس سے اس کو یہ محسوس ہوتا کہ وہ اس کے ساتھ خاص تعلق رکھتے ہیں۔
بڑے وضعدار، فیاض اور مہمان نواز تھے جس سے جس قسم کے تعلقات تھے، اس کو عمر بھر نباہا، ملازمت کے زمانہ میں ان کا دستر خوان بڑا وسیع اور گھر مستقل مہمان خانہ تھا، ان کے اعزہ و احباب میں سے کوئی نہ کوئی ان کے یہاں مستقل مقیم رہتا تھا اور جس کو ضرورت ہوتی اس کی نقدی سے بھی مدد کرتے تھے، ہر حاجت مند کی مدد کے لیے ہر وقت تیار رہتے تھے اور اس کے لیے ایسے کام کر گزرتے تھے جس کی ہمت ہر شخص نہیں کرسکتا، وہ بڑے تنخواہ دار تھے لیکن جو کچھ کمایا سب صرف کردیا، اعظم گڑھ میں دو ہی ایسے شخص تھے جنھوں نے بہت پیدا کیا، مگر اپنے بعد کچھ نہیں چھوڑا، ایک مرزا صاحب، دوسرے اقبال سہیل مرحوم ملازمت سے ریٹائر ہونے کے بعد حکومت نے ان کے سامنے پبلک سروس کمیشن کی ممبری پیش کی، مگر انھوں نے وطن چھوڑنا پسند نہ کیا اور اعظم...

قرآنی معاشرتی احکام اور لفظ لعلکم: حکم و عصری اطلاقات

In the Holy Quran, Allah has mentioned many such social rules that are very important for the peace & stability of a society and welfare of human beings. This article will not only highlight the word “La'allakum” in terms of meaning, diction and eloquence but also explain its usage for different purposes. Apart from this, in this article light will be thrown on such social rules that have been defined under the word “La'allakum" along with its philosophy and their implementations in the present era.

Studies on the Submerged Fermentation of Invertase by Saccharomyces Cerevisiae

In the present study, eighty six strains of Saccharomyces cerevisiae were isolated from different samples of fruits and soil by serial dilution method. The strain IS-66 gave maximum extracellular invertase production (1.10 U/ml). The enzyme activity reached to 5.6 U/ml when incubation time (48 h), sucrose concentration (5 g/l) and pH 5.5 were optimized. The wild strain IS-66 was exposed to ultraviolet (UV) radiations to obtain a mutant with improved enzyme activity. UV induced mutagenesis did not produce any stable mutant and almost all of the mutants produced relatively lesser invertase than the parental strain. Strain IS-66 was further subjected to chemical mutagenesis using nitrous acid and ethyl methane sulphonate (EMS). After extensive screening, two mutants were developed with increased enzyme activity NA-45 (20.74 U/ml) and EMS-42 (34.2 U/ml) from the wild-culture (IS-66). The mutant strain EMS-42 was cultured on the medium containing 2-deoxy-D-glucose (2dg) and its stability in invertase production was determined at different concentrations of 2dg. The concentration of 0.04 mg/ml was found optimal, as at this concentration EMS-42 showed consistent enzyme activity. Six media were evaluated for the production of invertase in shake flasks. M1 medium (g/l) containing yeast extract 3, peptone 5 and sucrose 30 g/l gave better production of invertase (25.28 U/ml) after 48 h of inoculation. Different sugars such as sucrose, glucose, fructose, lactose, galactose, maltose, raffinose and molasses were investigated on the enzyme production. Of these, sucrose was found to be best (44.03 U/ml) after optimizing the concentration at 10 g/l. Incubation temperature (30oC), inoculum size (2.0 %, v/v) and volume of the medium (50 ml/250 ml Erlenmeyer flask) were optimized. The effect of different additional nitrogen sources such as organic, inorganic and agriculture byproducts were also tested. Peptone at the concentration of 6 g/l gave maximum production of invertase (50 U/ml). The addition of inorganic nitrogen sources and agricultural byproducts nitrogen were not found to have any impact on the enhancement in enzyme production rather it was decreased from the control especially in case of agricultural byproducts. In stirred fermentor (7.5 L), the scale up studies for invertase production was carried out. The enzyme production (65.12 U/ml) was obtained after 24 h of incubation. The overall increase in enzyme activity (15 U/ml) and fermentation time was shortened by 24 h while scaling up enzyme production from shake flask to fermentor. The maximum enzyme activity (80.06 U/ml) was achieved after xvioptimization of cultural conditions such as sucrose (15 %, w/v), pH (4.5), inoculum size (7.5 %, v/v), agitation intensity (240 rpm) and aeration rate (1 vvm, 10 % DO). The intracellular enzyme activity was also determined by sonication. The maximium enzyme activity (57 U/ml) was found in mutant strain of EMS-42 after 24 h fermentation in the fermentor. During sonication, the maximum specific activity of 106 U/mg of protein was obtained with 0.5 duty cycle of impulses at amplitude of 40 % and pH 5 for 60 min. The calcium alginate entrapment technique was used for immobilization of whole cells of S. cerevisiae EMS-42 to form inverted syrup. It was noticed that maximum sucrose hydrolysis (63.40 %) was achieved after 18 h of incubation time. By optimization of cultural conditions for sucrose hydrolysis, the maximum hydrolysis percentage (76.3 %) was obtained at 50oC, pH 5.5 using sucrose (60 %) as substrate. An extracellular invertase was purified to homogeneity by two step purification i.e., ammonium sulfate precipitation and DEAE-Sephadex A-50. The enzyme was present in the supernatant of 85 % saturation being glycoprotein in nature. DEAE column chromatography eluted the enzyme as single active fraction at 0.2 M NaCI. The enzyme was purified by 15 fold with recovery of 38 %. The molecular mass of 110 kDa was determined after SDS-PAGE. The carbohydrate content was found to be 48 %. The intracellular invertase contains both forms of glycosylated (large) and non-glycosylated (small). The same procedure was applied for glycosylated intracellular invertase (L- form) while three purification steps were performed for non-glycosylated invertase (S- form). The L-form was purified by 19 fold with recovery of 32 %. Like extracellular invertase, the molecular weight (110 kDa) for L-form was found. Ammonium sulfate precipitation separated the enzyme (S-form) as insoluble fraction. This form of enzyme was eluted at 0.3 M NaCl using DEAE-Sephadex. A single band of molecular weight (55 kDa) was estimated after Sephadex G-50 with purification (16 fold) and recovery of 17 %. For both purified non-glycosylated and glycosylated invertase the optimum pH (5) was same whereas optimal temperature, MnCl 2 and the values of the K m and V max were found to be as 50 and 60oC, 109 and 111 %, 1.2 and 1.8 mM, 909 and 1429 U/ml/min, respectively.
