Lesson 30: Duality In Linear Programmingguest463822
Every linear programming problem has a dual problem, which in many cases has an interesting interpretation. The original ("primal") problem and the dual problem have the same extreme value.
Deepening Democratic and Civic Space Across the MENA Region Strategy 2013 — 2018Jamaity
Democratically elected governments understand the need to liberate and utilize the potential of civil society, this would enhance the chances of successful transitions. If other MENA governments took heed and expanded democratic and civic space without waiting for mass protests to spill over into violence, this would stabilize the region. A lasting solution to chronic instability and skewed development lies in democratic reform with active civic participation.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
