Dilema of Democracy & Political Leadership Crisis in Pakistan

Dilemma of Democracy & Political Leadership Crisis in Pakistan Overview Since mid 20th century,  Democracy is being considered the most accomplished process and a form of government where only people’s representatives have the right and authority to run the affairs of the state including forming certain constitutional rules and regulations.  Through democracy, people choose their representatives following a well-defined system of voting. The elected representatives then govern the affairs of the state on behalf of their people for a certain period of time (usually 4 to 5 years).  These representatives actually ensure the authority and rule of law for their people in the larger interests of any nation, state, or country. On the other hand, they are also held accountable and responsible for their actions and exercising of the powers within certain limitations as defined in the constitution or legislated through parliament.  Although Pakistan is a pure democratic...

Quantitative Reasoning Statistical Basics

Measures of Central Tendency Measures of central tendency are the specific statistical values which describe the typical values or central position of a dataset. The three most common single statistical values include Mean, Median and Mode.  Arithmetic Mean : Average of all values (sum divided by count). Geometric Mean : nth root of the product of values (used for growth rates). Harmonic Mean : The Reciprocal of the average of reciprocals (used for rates like speed). Median : Middle value when data is ordered. Quartiles : Values dividing data into four equal parts (Q1=25th, Q2=50th=median, Q3=75th percentile). Mode : Most frequent value. Measures of Dispersion Range : Difference between maximum and minimum values. Quartile Deviation : Half the interquartile range (Q3 - Q1)/2. Mean Deviation : Average absolute deviation from the mean. Variance : Average squared deviation from the mean. Standard Deviation : Square root of variance (spread in original units). Coefficient of Varia...

AFGHANISTAN CRISES: WHERE DOES PAKISTAN STAND?

Afghanistan Crises and Pakistan  Background According to history, Afghanistan has remained a war zone and a plan to invade central and south Asia for a long time. All of the invaders' troops entered South Asia through Afghanistan, from the Aryans to the Mughals. Afghanistan was the target of two major invasions in recent history. The former Soviet Union (USSR) launched its first invasion in December 1979, which lasted until 1989 and culminated in the dissolution of the Soviet Union into a number of distinct states. However, a significant portion of the formal USSR's territory, now known as the Russian Federation, is still there. As a result of the so-called September 11, 2001 attacks on the World Trade Center in New York, the United States of America (USA) and its NATO (North Atlantic Treaty Organization) allies, including Great Britain, launched the second invasion in 2001. Al-Qaeda's leader, Usama Bin Ladin, was allegedly blamed for the 9/11 attacks and claims that Al-Qa...

Social Media Literacy and Educational Approaches in the 21st Century Teaching & Learning Context: B.Ed Honours Course Content

Social Media Literacy & Modes of Education in 21st Century (B.Ed Honours) Course Content Introduction The term social media refers to the digital interaction among different social groups. One of the most integral aspects of human life in the 21st century is social media, and it has significantly transformed how individuals communicate, interact, and gain information. Social media has opened the door to new opportunities for learning and information sharing including diverse challenges for teachers and learners in the process of teaching and learning.  In less advanced countries like Pakistan, teachers are still reluctant to use social media platforms while teaching because they lack certain skills to use different social media platforms effectively. As a result of it, such teachers rely on outdated traditional methods of teaching. On the other hand, many students believe that the purpose of social media use is just for entertainment and informal interaction with digital friend...

BOOKS ARE THE BEST OF ALL THE FRIENDS!

Books are the Best of all the Friends  Overview: Francis Bacon rightly said that “some books are tasted, others to be swallowed, and some few to be chewed and digested”. In his quote, Bacon emphasized that there are very few books only to be read out as wholly because they draw our attention with diligence and develop curiosity as we go on reading them further and further. Actually, books are the food for our brains and thoughts. They provide us knowledge, and deep information and develop creativity along with critical thinking skills.  Books lead us towards a world of fantasy and imagination and pose various logical and rational questions and intend to seek our reflection. According to Charles W. Eliot, “books are the quietest and most constant of friends; they are the most accessible and wisest of counselors, and the most patient of teachers”. Books are best friends and they are always ready to talk to us and share their information and experiences with us. Books are mi...
