As the time goes on, the need for software applications is growing in every business, industry and for every event in life. One big challenge for software engineering is to test these increasing number of software applications. Software testing is a process to execute the software with the intent to verify its functionality. It also validates its process of development. Size of the program is one of the major concerns for tester during software testing. As thousands of lines of code are not easy to debug and test. The larger code makes the program complex. A program is analyzed to reduce program complexity. Program slicing is the program analysis technique that breaks the program code into smaller pieces. This research study proposed program slicing technique for object-oriented software testing to reduce program complexity. Object-oriented feature ?polymorphism? is taken as the subject for the program slicing techniques to minimize the overall testing cost and maximize the fault detection ability. This research proposed a program slicing technique for testing Object-Oriented systems by the use of adequacy measures code coverage and mutation analysis. Java programming language is considered for experiments of the proposed program slicing technique. Inclusiveness and precision metrics are used to evaluate the results of the experiment. These metrics are used for the assessment of test suite completeness and effectiveness.

تعلیم کی اہمیّت

تعلیم کی اہمیت
جہاں تک دیکھیے تعلیم کی فرمانروائی ہے
جو سچ پوچھو تو نیچے علم ہے اوپر خدائی ہے
تاریخ کی ورق گردانی کریں تو یہ بات اظہر من الشمس ہے کہ اس دنیا کے اندر جو بھی کارہائے نمایاں سر انجام دیے گئے وہ صرف اور صرف تعلیم ہی کی بدولت تھے ۔تعلیم ایک فرد میں جرأت مندی حوصلہ، دلیری، ثابت قدمی، قناعت پسندی ، صداقت، لیاقت، امانت اور دیانت جیسی عظیم صفات کی موجودگی کا سبب بنتی ہے۔
قرآنِ پاک کا مطالعہ کریں تو پتہ چلتا ہے کہ تعلیم کی کتنی اہمیت ہے۔ حضرت آدم ںمسجودِ ملائکہ بنے تو تعلیم ہی کے ذریعے یعنی اللہ تعالیٰ نے آپؐ کو اشیاء کاعلم سکھا دیا۔ طالوت کو بادشاہت ملی تو سبب علم ہی کو بتایا گیا۔ اگر حضرت یوسف کو سیاہ و سفید کا مالک بنایا گیا اور مصر کی بادشاہت ملی تو اس کا سبب بھی تعلیم ہی بنی۔ آپؐ نے فرمایا کہ اِنّی حَفِیْظ عَلم علا وہ از یں متعدد مقامات پرتعلیم ہی کا ذکر ہے کہ اس کے ذریعے کا ئنات میں مختلف امور سرانجام دیے گئے۔ اللہ تعالیٰ نے حضرت محمد صلی اللہ علیہ و آلہٖ وسلم کو ہر اس شے کا علم عطا فرمایا جو آپ صلی اللہ علیہ و آلہٖ وسلم نہیں جانتے تھے۔ ارشادِ باری تعالیٰ ہے کہ’’ اور سکھادیاتمہیں جو تو نہیں جانتا تھا‘‘(القرآن) اللہ تعالیٰ کی ذات کے بعد اگر کسی ہستی کا مرتبہ علیٰ و اَرفع ہے تو رسول اللہ صلی اللہ علیہ و آلہٖ وسلم کی ذات ہے لیکن اس کے باوجود بھی وہ یوں دعا کرتے ہیں کہ ’’یارب العالمین میرے علم میں اضافہ فرما‘‘تعلیم کی اہمیت ہر دور میں مسلمہ رہی ہے۔
حدیث نبوی میں ہے کہ:
’’ علم حاصل کرو گود سے لے کر گورتک‘‘ (الحدیث)

Pelaksanaan Pembelajaran Jarak Jauh Di Masa Pandemi Covid-19

Penelitian ini dilatar belakangi oleh adanya kondisi pandemi Covid-19 yang berdampak pada ranah pendidikan. Untuk memenuhi hak peserta didik dalam mendapatkan layanan pendidikan, SD Negeri Karangasem baru pertama kali menerapkan pelaksanaan  pembelajaran  jarak jauh, perubahan pola pembelajaran secara tiba-tiba ini menimbulkan berbagai kendala yang harus dihadapi sehingga guru harus melakukan berbagai upaya agar pembelajaran dapat tetap berlangsung meskipun di masa pandemi Covid-19. Jenis penelitian ini adalah kualitatif dengan pendekatan studi kasus yang bertujuan untuk mendiskripsikan pelaksanaan pembelajaran jarak jauh serta mengetahui upaya yang dilakukan guru untuk mengatasi kendala dalam pelaksanaan pembelajaran jarak jauh selama pandemi Covid-19. Hasil penelitian menunjukkan bahwa pembelajaran jarak jauh pada masa pandemi Covid-19 di SD Negeri Karangasem Kabupaten Demak dilaksanakan dengan pola  daring, luring dan home visit. Adapun upaya yang dilakukan guru untuk mengatasi hambatan dalam melaksanakan pembelajaran jarak jauh pada masa pandemi Covid-19 yaitu kembali kepada kebijakan dan kemampuan guru itu sendiri. Hal itu karena sudah menjadi tanggung jawab guru untuk mengelola pembelajaran, termasuk mencari jalan keluar bagi setiap hambatan yang terjadi selama pembelajaran.

Tracking the Dynamics of Interaction Between Fiscaland Monetary Policy in Pakistan

Politicians, policy makers and economic managers want to spur economic growth, bring economic stability and to create jobs. Economic growth is not only affected by macroeconomic policies but it is also prone to various types of shocks. Appropriate and timely policy response can at least minimize, if not completely escaped, the distortions and loses associated with shocks. Optimization of economic growth and its sustainability demands the execution of good macroeconomic policies in general and fiscal and monetary policy in particular. Some time fiscal policy seems to be more effective while the environment is more favorable for monetary policy in other times. We also know that both fiscal and monetary policy have different objective with different policy instruments. The macroeconomic situation of Pakistan’s is very depressing and the situation demands stark assessment of its macroeconomic policies particularly fiscal and monetary policy. The objective of this thesis is to investigate the interaction between fiscal and monetary policy using small scale open economy dynamic stochastic general equilibrium model. This thesis explores the responsiveness of monetary policy to fiscal policy vis-à-vis explore the fiscal implications of monetary policy. As we assume a small scale open economy, we also explore the responses of fiscal and monetary policy interaction to technology and foreign output shocks. We also countercheck few results using the techniques of autoregressive distributive lag model. Our findings reveal the existence of interaction between fiscal and monetary policy in Pakistan. The response of interest rate to fiscal policy, particularly to tax shock is positive. Fiscal and monetary policy behaves as a strategic complements. This is not a good sign for a crippling economy like Pakistan’s as two important macroeconomic policies are contractionary simultaneously. Similarly when it comes to spending component, interest rate negatively responds when government increases spending. Both fiscal and monetary authority adopts expansionary policies simultaneously. We also find that higher interest rate discourage government borrowing. Inflation responds negatively to interest rate in DSGE set up while the phenomenon of price puzzle exists in ARDL schemes of things. The response of inflation is positive to both higher taxes and government spending. Government spending reduces in response to a monetary policy shock. Tax revenue also reduces when interest rate shock occurs in the economy. Inflation also raises the revenue from taxes but is very short lived.
