زاہدہؔ صدیقی(۱۹۴۷ء پ) کا قلمی نام زاہدہؔ ہے۔ آپ برہان پور پسرور میں پیدا ہوئیں۔ آپ معروف شاعر حفیظ صدیقی کی حقیقی بہن ہیں۔ آپ کا ابتدائی کلام ماہنامہ ’’تحریریں‘‘ میں چھپتا رہا۔ آپ ’’تحریریں‘‘ کی مدیر بھی رہیں۔ زاہدہؔ کے دو اردو شعری مجموعے ’’جاگتی آنکھوں کے خواب ‘‘اور ’’دعاؤں کا سائبان‘‘ شائع ہو چکے ہیں۔ اردو کے علاوہ آپ کے دو پنجابی شعری مجموعے بھی طبع ہو چکے ہیں۔(۱۰۳۷)
زاہدہ صدیقی نے اپنی شاعری میں اپنی ذات کو عالمِ نسوانی کے ایک فرد کی علامت کی صورت میں پیش کیا ہے۔ ان کی شاعری اس لحاظ سے بہت خوشگوار ہے کہ انھوں نے اپنی ذات کو اپنے لیے مجلس نہیں بنایا بلکہ اس کی فصیلیں گرادی ہیں۔ اور اپنی شاعری کے ذریعے نوجوان شعرا کو تازہ ہوا اور کھلی دھوپ سے فیض ہو نے کا درس دیا ہے۔ رجائیت ،رومانیت اور عشقِ حقیقی زاہدہؔ کی شاعری کی خصوصیات ہیں ۔ ا س حوالے سے کچھ اشعار ملاحظہ ہوں:
ایک احساس
صبحِ اُمید کی جس کرن کے لیے
ہم سے پہلے بھی کچھ لوگ
تاریک راہوں پہ چلتے رہے
آج ہم بھی
انھی تیرہ و تار راہوں پر چلتے ہوئے
سوچتے ہیں
کہ شاید
کسی روز اپنا مقدر بنے
صبح اُمید کی وہ کرن
جو ابھی تک
نگاہوں سے مستور ہے(۱۰۳۸)
جاگتی آنکھوں کا خواب
زندگی
اک جاگتی آنکھوں کا خواب
خواب جو دیکھا نہ پہچانا گیا
ایک ساعت
آدمی کو اس کے ہونے کا یقین
دوسری ساعت
بکھر جائے فضاؤں میں کہیں
اک دریدہ لباس آوازِ جرس
جیسے اس کی کوئی منزل ہی نہیں (۱۰۳۹)
ترا خیال اُتارے دل و نظر کا غبار
ہر اک بجھی ہوئی صورت نکھر بھی سکتی ہے

Pakistan’s involvement in the US war on terrorism was a tragic decision. No option was left for the ruling elite of Pakistan except to join the global war on terrorism and to take a U-turn from the support of Taliban’s regime in Afghanistan which was duly recognized by Pakistan’s government in 1996. It was expected by the policy-makers of the US that the alliance with Pakistan would provide extraordinary strength in combating the Al-Qaeda and other affiliated conglomerates in Afghanistan as well as in borderland area. However, after fifteen years of war, the alliance has enfeebled despite their mutual understanding regarding the objectives envisaged in the Strategic Partnership. The war on terrorism has now been escalated from Afghanistan to Pakistan and it has provided space to religious extremism, militancy, intolerance, ethnic division and sectarianism. There is no denial to the fact that religious extremism and terrorism are common threat and have damaged both the countries yet Pakistan has sacrificed more than the US in terms of human and material loss. Nevertheless, blame game and trust deficit is on the rise from both sides. This article focuses first on the joint ventures that the US and Pakistan mutually initiated to curb militant bloodbath in Afghanistan as well as in the border region. Secondly, it will explore factors responsible for increasing trust deficit between the partners. The study will not only provide deep understanding about the prevailing issues between Pakistan and the US but will also give true pictures to streamline the methodology for negotiating with each other in future.
In wireless cognitive radio networks, natural antagonism arises among unlicensed users when nodes opportunistically compete for unused frequency bands and the operations are seriously hampered by acute scarcity of resources. The transmitted power, which is inherently pertinent to the signal-to-interference-plus-noise ratio, cog- nition methodology, and lack of central management, must be preserved for longer network lifetime. In the midst of this struggle to acquire desired frequency band, where the performance of the entire network is dependent upon the behavior and etiquette exhibited by individual nodes, it is pivotal to introduce an e ective cooper- ation mechanism in order to improve the vital network parameters. In this work, we employ the concepts of game theory to develop an e cient and sustainable coopera- tion mechanism for e cient cognition and improved spectrum utilization. Instead of focusing merely on the interference a user observes, cooperation is ensured by taking into consideration the amount of interference a user creates for other network users. With the introduction of unlicensed users in licensed bands, the operations and interests of licensed users need to be protected, hence the spectrum owners are given an advantage and control over the multiple access policy. We address the problems in spectrum access and channel selection equilibrium in a leader-follower setup. In contrast to the game formulations that lack e cient power and pricing schemes, we present a cooperative Stackelberg potential game for cognitive players. A dynamic cost function is articulated to induce awareness in players to mitigate the e ects of sel sh choices in spectrum access while at the same time steer the distributive network towards achieving Nash equilibrium. The proposed scheme is mutually bene cial for i ii all players and focuses on improving the network performance and power e ciency. We design the network potential function such that the nodes have performance based incentives to cooperate and achieve a Nash equilibrium solution for e cient channel acquisition and capacity. Simulation results show fast convergence in channel selection strategies and increase in capacity for the entire network. In order to avoid anarchy in this uncontrolled and sometimes hostile environment, it is important to inhibit the nodes in making potentially risky decisions that may eventually jeopardize the stability and performance of the entire network. We present a game theoretic approach to combat the e ects of uncontrolled and sel sh behav- ior exhibited by cognitive network nodes. A sustainable solution is proposed that employs nonlinear learning in conjunction with potential function to alleviate the im- plications of disruptive behavior that is usually demonstrated in the access of scarce spectrum resources. The regret information in decision making is exploited along with history statistics to minimize information exchange and achieve swift convergence of strategies. Moreover, incorporating learning allows the cognitive players to select the channels in a simultaneous fashion instead of waiting for their turns to change their channel choices. This considerably reduces the delay in achieving network stability.
