Week 2: Assignment Instructions
In each week the learning assignment is designed to demonstrate your competence with the Terminal Course Objectives of the course. Prior to working on the assignment, you should read through the weeks chapters and lesson.
Clearly identify your work with your name, the date, the week number and the assignment name, and upload work to the Dropbox.
The questions are designed to probe the higher levels of thinking and learning such as analyzing, evaluating and creating, and so there often are no correct answers. Instead of focusing and who wins or loses the case, you should analyze, evaluate and create alternative solutions to the various issues presented while arguing and debating the connections between business, law, politics and ethics.
Terminal Course Objective: G
Case Study: International and World Trade Law - Counterfeiting
Write a 1-2 page reflective paper (double spaced) on the following questions while discussing the connections between business, law, politics and ethics.
One: There has been a movement in the last decade encouraging people to buy American. Discuss the legal and ethical issues related to boycotting goods from other countries. What are the practical business implications of such a move?
Two: The World Trade Organization, or WTO, is the largest and most influential of the trade organizations. China and other heavy counterfeiting nations are part of this group. What could WTO-participating nations do to address the problems of counterfeiting? What should they do?
Three: The United Nations Security Council, the main decision-making body at the UN, is comprised of five regular members: China, France, the Russian Federation, the United Kingdom and the United States. Ten more members are elected from the General Assembly. Given the make-up of the committee, what type of action might the UN take with regard to the counterfeiting issue?
Submit your assignment to the Dropbox.

Over four class periods, the students learned about geometric optics concepts including the laws of reflection and refraction, total internal reflection, and applications involving ray optics experiments. The lessons involved reviewing concepts, presenting examples, discussing new skills like solving context-rich problems, and evaluating student learning through activities and problems. Formative assessments were given to check student understanding of key ideas like Malus' law governing the transmission of light through polarizers. The log included reflections on teaching strategies, student performance, and areas for improvement.

This document is a daily lesson log for a Grade 12 physics class taught over four days. It details the objectives, content, learning resources and procedures for lessons on reflection, refraction, and mirrors/image formation. The objectives are for students to understand and apply concepts of reflection, refraction, total internal reflection, and their applications. Students practice solving problems involving these optics concepts. Activities include reviewing concepts, group work, and solving sample problems about mirrors and lenses.
AC current efficiently transfers over long distances, providing more power using rotating magnets that cause electrons to flow directionally at frequencies of 50-60Hz, changing direction forward and backward. It is produced by generators and has impedance as its passive parameter with a power factor between 0 and 1, including sinusoidal, trapezoidal, triangular, and square wave forms. DC current loses power over long distances with steady magnetism causing electrons to flow in one direction at zero frequency, moving steadily forward. It is produced by cells or batteries and has resistance as its only passive parameter with a power factor always of 1, including pure and pulsating forms.

His first career was in broadcasting, where he designed and built commercial radio station studios in Manchester, Cardiff and Bristol, also working as a presenter and programme producer. Tim now writes and presents extensively on matters relating to the human and neurological aspects of projects, including communication, ethics and coaching. He holds a Masters degree in NLP, is an NLP Master Practitioner and International Coach. He is the Deputy Lead for APMs People Interest Network.
Session | The Neurological Levels of Team-working: Harmony and Tensions
Understanding how teams really work at conscious and unconscious levels is critical to a harmonious workplace. This session uncovers what those levels are, how to use them to detect and avoid tensions and how to smooth the management of change by checking you have considered all of them.
Blind Spots in AI and Formulation Science Knowledge Pyramid (Updated Perspect...Ajaz Hussain
油
This presentation delves into the systemic blind spots within pharmaceutical science and regulatory systems, emphasizing the significance of "inactive ingredients" and their influence on therapeutic equivalence. These blind spots, indicative of normalized systemic failures, go beyond mere chance occurrences and are ingrained deeply enough to compromise decision-making processes and erode trust.
Historical instances like the 1938 FD&C Act and the Generic Drug Scandals underscore how crisis-triggered reforms often fail to address the fundamental issues, perpetuating inefficiencies and hazards.
The narrative advocates a shift from reactive crisis management to proactive, adaptable systems prioritizing continuous enhancement. Key hurdles involve challenging outdated assumptions regarding bioavailability, inadequately funded research ventures, and the impact of vague language in regulatory frameworks.
The rise of large language models (LLMs) presents promising solutions, albeit with accompanying risks necessitating thorough validation and seamless integration.
Tackling these blind spots demands a holistic approach, embracing adaptive learning and a steadfast commitment to self-improvement. By nurturing curiosity, refining regulatory terminology, and judiciously harnessing new technologies, the pharmaceutical sector can progress towards better public health service delivery and ensure the safety, efficacy, and real-world impact of drug products.
