مغربی تنقید کے اہم نام

موضوع 9:مغربی تنقید کے اہم نام
پس منظر:
لان جائنس کے بعد۱۳۰۰ سال تک خاموشی رہتی ہے اور پھر "دانتے" کے آنے سے یہ خاموشی ٹوٹتی ہے۔انگلستان میں "فلپ سڈنی" ، فرانس کے "بولو"ڈرائیڈن ، پوپ، جانس، گوئٹے، ورڈز ورتھ، کولرج وغیرہ جیسے قابل ذکر نام ہمارے سامنے آتے ہیں۔
ورڈزورتھ:
ورڈز ورتھ کا تعلق انگلینڈ سے تھا۔ اس کی ملاقات کولرج سے ہوئی اور مل کر سوچا جو شاعری ہو رہی ہے اس میں کوئی نئی بات نہیں ہے۔لہذا وقت کی ضرورت ہے کہ انگریزی ادب میں تبدیلی لائیں تاکہ مقصدیت کو بھی ہو۔ لوگوں کو فائدہ بھی ہوگا اس کے لیے ماحول تیار کرنے کی ضرورت ہے۔ ورڈزورتھ نے اپنی کتاب"کلیریکل بلیڈز " کے دوسرے ایڈیشن میں ایک مقدمہ یعنی تمہید لکھی۔جیسے مقدمہ شعر و شاعری میں حالی نے شروع میں جو صفحات لکھے اردو ادب میں ان کو بنیادی اہمیت حاصلہے۔ اسی طریقے سے جو تمہید ورڈزورتھ نے لکھی وہ تنقید کا پورا راستہ متعین کرتی ہے۔اس میں انہوں نے اپنا نکتہ نظر اور ماہیت بیان کی۔ انہوں نے بتایا کہ نئی شاعری کس طرح کی ہونی چاہیئے۔اس کے قواعد و ضوابط کیا ہوں۔ورڈز ورتھ کی تمہید اس اعلان سے شروع ہوتی ہے :
"شاعری بادشاہوں، امیروں اور نوابوں کے لیے نہیں ہے۔اب وہ دور ختم ہوگیا جب اس بات کا خیال رکھا جاتا تھا کہ بادشاہوں کو جو پسند ہے وہ لکھا جائے۔ اب جو موضوعات اور زبان کا معیار ہے وہ لکھا جائے۔اس کے لیے کچھ اصول متعین کیے جانے ہیں۔انہی پر عمل کیا جائے گا۔ اب زبان اور موضوع شاہی دربار سے نکل کر عوام میں واپس آجائے گا۔"
ورڈزورتھ نے جو تھیوری پیش کی اس کا مطلب یہ ہے کہ اب عوام کے لیے لکھیں۔ ورڈزورتھ نے لکھا کہ:

عمران اقبال کی افسانہ نگاری میں تانیثی شعور

Imran Iqbal's name is prominent in Urdu fiction. He is from Bahawalpur but he is residing in the United States for employment. Imran Iqbal tried his hand at travelogues, fiction, novels and memoirs. He has made women and her issues the subject of his fictions. Imran Iqbal has presented a true picture of a woman who at every step faces various forms of male repressive behavior, outdated customs, husband and father-in-law atrocities, domestic violence and sexual harassment. Her fiction depicts women's psychological problems, the sexual appetites of landlords, capitalists, bureaucrats and top officials. Imran Iqbal has awakened Tanila consciousness through his pen.

Impact of Foreign Exchange Exposure Elasticity on Idiosyncratic Risk, Foreign Ownership and Financial Distress of Firms: A Comparative Analysis of Developed and Emerging Economies.

This study makes comparison between an emerging economy (Pakistan) and a developed economy (USA) regarding effect of the foreign exchange exposure elasticity on financial distress, idiosyncratic risk, and foreign ownership of the firms. It also tests effect of the global financial crisis 2007-09 on the relationship between the foreign exchange exposure and financial distress of the firms. The study takes all non-financial firms of Pakistan Stock Exchange and all non-financial firms from S&P-500 index of US companies for a period of 2003 to 2015. It conducts a quantitative analysis of panel data of the sample firms followed by views of Chief Finance Officers of the companies. Asset pricing model and rolling regression technique are used for calculating foreign exchange exposure elasticity. It mainly uses multiple regression analysis using White’s Heteroskedasticity-consistent standard errors & covariance test, fixed effect, random effect and Logit model. The results show that the effect of foreign exchange exposure on the financial distress of Pak firms is positively significant at contemporaneous as well as lag level. The effect of the foreign exchange exposure of US manufacturing firms on their financial distress is also positively significant at contemporaneous and lagged level but a weak contemporaneous and lagged effect in case of US non-financial firms. The effect of the global financial crisis is significant during all the three years of the crisis (2007 09) in case of US firms but firms in Pakistan experienced this effect only during 2009. ix This study uses Fama–French three factor model and EGARCH for calculating idiosyncratic risk. The effect of the foreign exchange exposure elasticity on idiosyncratic risk of both the Pakistani and US firms is highly positively significant at contemporaneous as well as at lag level. We find a negative impact of the foreign exchange exposure elasticity on the foreign ownership in the Pakistani firms. In case of the US firms, the relation is insignificant. The study has a number of implications regarding financial stability of the firms, their idiosyncratic risks and of foreign equity. This study is unique on the relation between foreign exchange exposure and financial distress in Pakistan and adds in the literature on USA in this dimension. It also gives a good insight on valuation of firms taking foreign exchange exposure and idiosyncratic risk into consideration. The study makes number of valuable recommendations for carrying out future research on this domain.
