کلرک کا نغمہ محبت کا تنقیدی جائزہ
میرا جی کے سماجی شعور کااظہار ان کی کئی نظموں میں ہوا ہے۔ جہاں چھوٹے طبقوں سے ان کی واضح وابستگی کا اندازہ ہوتا ہے ان کی نظمم کلرک کانغمہ محبت اس کی بہترین مثال ہے۔
متوسط طبقے کی ذہنی عکاسی:
سب رات مری سپنوں میں گزر جاتی ہے اور میں سوچتا ہوں
پھر صبح کی دیوی آتی ہے
اپے بستر سے اٹھتا ہوںمنہ دھوتا ہوں
لایا تھا کل جو ڈبل روٹی
اس میں سے آدھی کھائی تھی
باقی جو بچی وہ میرا آج کا ناشتہ ہے
اس بندمیں جس طرح ایک متوسط طبقے کے شخص کی ذہنی عکاسی کی گئی ہے۔ وہ مشاہدے کی زیر کی دلیل ہے۔ متوسط طبقے کا یہ شخص کیسے ایسے سہانے خواب دیکھتا ہے لیکن حقیقت یہ ہے کہ رات کی بچی ہوئی روٹی کھا کر دفتر روانہ ہونا پڑتاہے۔ حقیقت اور سپنے کا یہ تضاد میر ا جی کے مشاہدے کی دلیل تو ہے ہی ‘ کلرک کے ساتھ ان کی وابستگی اور اس کے مسائل کو اسی کی سطح پر اتر کر سمجھنے کی ایک کوشش بھی ہے۔ اس نظم میں محرومیوں کا طویل سلسلہ ہے جن سے اس نظم کا مرکزی کردار گزرتاہے۔ ا? س پاس کی ا?سائشوں اور لوگوں کے اطمینان و سکون کو دیکھتا دفتر پہنچتا ہے۔ اور اپنے افسر کی فضول باتیں سنتا ہے۔ نظم کا اختتام ان سطروں پر ہوتا ہے۔
پل بھر کے لیے اپنے کمرے کو فائل لینے ا?تا ہوں
اور دل کی آگ سلگتی ہے میں بھی جو کوئی افسر ہوتا
اس شہر کی دھول اور گلیوں سے کچھ دورمرا گھر ہوتا
اور تو ہوتی
لیکن میں تو اک منشی ہوں تو اونچے گھر کی رانی ہے
یہ میری پریم کہانی ہے اور دھرت سے بھی پرانی ہے

This paper is formulated under the conceptual framework of Gayatri spivak’s theory of Can Subaltern Speak? And explores the potential permeability of visual resources as a form of discourse through which subalterns found opportunity to counter media hegemony and make their voices heard. In order to analyze the selected graphic novel Munnu: A Boy From Kashmir (2015) the present qualitative study applies Grunter Kress and Theo Van Leeuwen’s model of visual design (2010) that connects the representational meaning to the interactive one. The analyst reflected upon how the interplay of visuals images and words together displayed the theme of Kashmir’s subjugation as well as how this genre has proved supportive to author to counter the said hegemony. Hence, the study found consent, political domination and media control as the broad elements that can be seen in the novel and also the study concludes that counter hegemony is possible through such literary genres, as the novel’s narrator has communicated those aspects of hegemonic situation in Kashmir to a large audience through literary discourse of graphic novel genre that are chiefly absent from mainstream media’s treatments of the Kashmir’s conflict. ______
Cognitiveradionetworks(CRNs)havegainedatremendousinterestintheresearch community, as they tend to solve the existing and future issues of frequency spectrum scarcity by exploiting the spectrum holes in underutilized licensed and unlicensed frequency bands, thereby, improving the spectrum utilization. The number of channels in a Cognitive Radio Network (CRN) always varies with time and location as compared to legacy wireless networks with fixed number of radio channels. This variability of available channels in cognitive radio networks has brought new design challenges in MediumAccessControl(MAC)protocolsandhasledtotheneedformostefficientand reliable MAC protocols in a CRN that can sustain under variable network conditions. Thesharingofdiscoveredspectrumholesamongthecontendingsecondaryusers(SUs) increases the overall spectrum utilization; however, the utilization of these discovered spectrum holes within the CRN depends on the access mechanism of SUs. In random access, waste of these spectrum holes would occur due to collisions and un-attempted slots by SUs. Therefore, optimal use of these discovered holes with minimum or no waste is desirable in an efficient CRN. A self- organizing collision-free MAC protocol isproposedforthedistributedCRNthatismoreefficientinspectrumsharingbyavoiding collisions and maximally utilizing un-attempted slots during access phase, thus increasing the spectrum utilization and throughput. This is achieved by organizing and queuing the active SUs through a timer value and directing them in an orderly fashion to use the discovered holes. Finding holes from the underutilized portion of spectrum at varying times and locations is the most important function in CRNs. This requires efficient sensing policy at the MAC layer that can discover more idle channels in minimal time. Spectrum sensing policies for searching idle channels from the underutilized primary band can significantly affect the performance of SUs in terms of throughput, reliability and en ergy efficiency. The sensing policy depends on the channel sensing order that decides how SUs sense the primary user band in minimal period of time. A cooperative parallel sensing scheme with sequential channel selection order is proposed as part of the MAC protocol, which can discover all the free channels in the primary user band in minimal time. The proposed scheme has been analyzed for the number of channels sensedandthenumberofidlechannelsdiscovered. Furthermore,energyefficiencyand throughput of the proposed scheme have also been evaluated. The results show considerable improvement for the proposed scheme as compared to the random channel spectrum sensing schemes prevalent in adhoc CRNs. The work in this thesis has aimed to improve spectrum management by adopting new spectrum sensing policies and improvingspectrumsharingbyself-organizingthecognitiveusersforcollisionfreeaccess in adhoc CRN MAC protocols.
