This is era of information. It is common to find the datasets with hundreds and thousands of features used by real world applications. Feature selection is a process to select subsets or features which are more informative. Feature selection technique is used to remove irrelevant and redundant features without losing much of the information. Recently Rough Set Theory (RST) becomes a dominant tool for FS. It is a theory which provides both data structures and methods to perform data analysis. Rough set theory has offered new ideas and trends for the features selection and deal with inconsistent information. Reduction of attribute is an important issue in rough set theory. Many feature selection techniques have been presented in literature using RST. However, majority of these techniques do not ensure optimal feature subsets and suffer serious performance bottlenecks especially in case of large datasets. In this thesis, we modified genetic algorithm to find subset of features within minimum execution time. In its conventional form, genetic algorithm is heuristic based approach; however, using genetic algorithm does not ensure the optimal feature sub selection. In this thesis, we have modified the algorithm such that the resulted feature subsets are not only the optimal but the resulting performance is also improved. The proposed approach was examined with other state of the art FS approaches various publically available datasets at UCI. Results show that efficiency and effectiveness of the proposed approach are better.

مفتی محمد عبداﷲ ٹونکی

مفتی محمد عبداﷲ صاحب ٹونکی

            اخبارات سے یہ خبر معلوم ہوچکی ہوگی کہ جناب مولانا مفتی محمد عبداﷲ صاحب ٹونکی نے ۷؍ نومبر ۱۹۲۰؁ء کو بعارضۂ فالج بھوپال میں انتقال کیا، مفتی صاحب مرحوم عربی درسگاہوں کی قدیم تعلیم کے بہترین نمونہ تھے، ہندوستان کے مشاہیر علماء میں ان کا شمار تھا، وہ ادب میں مولانا فیض الحسن صاحب اور دینیات میں مولانا احمد علی صاحب محدث کے شاگرد تھے، مولانا فیض الحسن صاحب کے انتقال کے بعد اورینٹل کالج لاہور کی پروفیسری کی جگہ ان کو ملی اور ان کی عمر کا بڑا حصہ اسی درسگاہ میں گزرا، اخیر زمانہ میں وہ دارالعلوم ندوہ کے مدرس مقرر ہوئے تھے اور اس کے بعد مدرسۂ عالیہ کلکتہ کے صدر مدرس ہوئے اور یہیں سے بیمار ہوکر اپنے صاحبزادہ جناب مفتی انوارالحق صاحب ایم، اے ناظم و مشیر تعلیمات بھوپال کے پاس گئے تھے جہاں انہوں نے وفات پائی، غالباً وفات کے وقت مفتی صاحب مرحوم کی عمر ستر (۷۰) کے قریب ہوگی، تعلیمی خدمات کے علاوہ مفتی صاحب کا بڑا کارنامہ انجمن مستشار العلماء لاہور ہے، جو ایک قسم کا دارالافتاء ہے۔ مرحوم نے بعض عربی کی درسی کتابوں پر حواشی بھی لکھے تھے۔ ان کی وفات سے علماء کی صف میں ایک ایسی جگہ خالی ہے جس کے بھرنے کی اب آئندہ امید نہیں۔

مغرب کا نظریہ ملکیت اور اسلام تقابلی جائزہ

Islam recognizes the right of individual ownership of material things in this world. A person can hold all kinds of Halal material things in his individual possession. However, Islamic Shari'a doesn't allow such a concept of individual ownership which is given in Capitalism and as adopted by Western world. The Western world's concept about individual ownership is very liberal and without any restrictions. While, Islam doesn't give full liberty to any individual but rather instructs them to own and possess Halal material things via legitimate sources, and also instructs the right usage of these material things in the light of Qur'an and Sunnah. The benefit of this Islamic law is that disqualified individuals, such as an insane person or children, have no right on disposing his or her individual property. Similarly, in the eyes of Islam, an individual person is not allowed to dispose his or her property in such a way which causes trouble and inconvenience to others, for example a person cannot dig a well on his own land which causes trouble and inconvenience to others. Islam prohibits such disposing of an individual's property.

School Principal As a Strategic Leader: A Case-Study of a Private Sector School in District Chitral in Khyber Pakhtunkhawa Kpk Pakistan

School leadership plays a significant role in determining the levels and quality of school improvement process and its outcomes. The position of the school principal is of a door keeper to change that means how he receives the guests and what are the arrangements to welcome and how to please the guests. The school culture, practices and structure mainly revolve around the principals’ qualities, specifically in the private educational systems. The educational reforms and the fast moving technological era demand that the school leaders can only survive if they have strategic leadership qualities. They also require a strong vision for the institution. To achieve this vision, there should be a strong mission with strategic working styles and measures. The leaders should have the vision, the ability to share the vision with people inside as well as outside the organisation and inspire them to work jointly to accomplish the vision. Strategic leaders are those who have different thinking powers than the ordinary leaders and far-sighted lenses and thought processes to any endeavor. They scan the current position of the institution with respect to its internal and external environment, anticipate change proactively, set goals and objectives, align the organisation’s culture to these goals and negotiate across a wide breath of stakeholders for the survival of the organisation and its continuous improvement. They reflect on the strategies used for improvement and sustain the change in the complex and uncertain changing context. The purpose of the study is to explore and understand the principal’s role as a strategic leader. It also aims at understanding the role of the principal’s practices and position with futuristic lens. Moreover, to understand the principal’s powers to compete in a competitive situation in rural private context and the strategies used to sustain in the education market. The study employed the exploratory case study method selecting one school in the rural context of Chitral, Khyber Pakhtunkhawa (KPK), Pakistan. Qualitative data gathering strategies, namely; document analysis, observations, semi-structured and focus group discussions were made use of. The data were categorised and classified on the basis of the themes focusing on the principal’s practices and functions. The study findings reveal that the principal’s role is essential for strategic development in schools and strategic planning is fundamental to move towards the strategic direction. Strategic role of the principals is important for the educational development in far-flung rural areas. This study may help educational
