...Anthropology Lecture 1 introduction Common Misconceptions with Drugs . The effect of a drug is caused solely by its pharmacological properties and effects. . Some drugs are instantly addictive . The gateway/ stepping stone theory - the use of 1 drug leads to the use of other more dangerous drugs What are drugs ? Krivanek's definition : Drugs are substances that are introduced into the body knowingly but not as food. Therefore illicit drugs, legal recreational drugs and legal but regulated pharmaceutical drugs that aren't recreational at all. - Whether if a drug is considered bad and is prohibited depends on the culture of the society in a particular period. What is culture ? The definition of culture = Through Roger keesing and Andrew Strathern's definition it is a system of shared ideas, rules and meanings that underlie and are expressed in the ways that human live. - This includes : law, beliefs, political economy, media and popular culture - this perceives ideas about what is normal and abnormal to society.

(2011). What’s mine is yours. How Collaborative Consumption is changing the way we live. HarperCollinsPublishers: London. 2 Summary Collaborative Consumption (CC) is a new socioeconomic groundswell in which traditional sharing, bartering, lending, trading, renting, gifting, and swapping are redefined through technology and peer communities. It is characterized by access, instead of ownership, to products and services thereby benefiting people, profit and planet. This ‘new’ form of sustainable consumption and entrepreneurship has the ability to transform business, consumerism, and the way people live (Botsman and Rogers, 2011). Examples of CC have been growing rapidly over the past few years. However, there is a dearth of empirical evidence about the actual growth potential of CC. Therefore, the knowledge gap addressed in this thesis is this dearth of empirical evidence and ultimately......

Leadership Development - Doe

...Leadership Development Seminars and ECQ-based Readings The success or failure of any endeavor depends on leadership. Now, more than ever before, we need leaders in our organizations and in our world. Great leaders create and communicate a vision and move people into action to achieve it. They ignite our passion and inspire us to do our best. Government leaders in the 21st century are experiencing change at a more rapid pace than previous generations. Rapid advances in technology have expanded the quantity of work we are capable of accomplishing, and also where it’s accomplished. We have a more highly educated workforce, yet face diminishing resources with an increased demand for productivity, and the essential services we provide to the American public. To be successful at navigating these challenges leaders must develop the essential skills to motivate their employees, effectively communicate with others, fine-tune critical thinking skills, and build and leverage partnerships. Future leaders must also be visionary; i.e., possess the ability to identify trends and the courage to be innovative. Being technically adept in your field will no longer be enough. In response to these demands on senior executives, the U.S. Office of Personnel Management identified five Executive Core Qualifications (ECQs) that all aspiring government leaders and executives must possess. These ECQs and Fundamental Competencies were developed by OPM after extensive research on the attributes...

...analytical tools of economics with the insights of business leaders. Our “micro-to-macro” methodology examines microeconomic industry trends to better understand the broad macroeconomic forces affecting business strategy and public policy. MGI’s in-depth reports have covered more than 20 countries and 30 industries. Current research focuses on four themes: productivity and growth, the evolution of global financial markets, the economic impact of technology and innovation, and urbanization. Recent reports have assessed job creation, resource productivity, cities of the future, and the impact of the Internet. MGI is led by McKinsey & Company directors Richard Dobbs and James Manyika. Yougang Chen, Michael Chui, Susan Lund, and Jaana Remes serve as MGI principals. Project teams are led by a group of senior fellows and include consultants from McKinsey’s offices around the world. These teams draw on McKinsey’s global network of partners and industry and management experts. In addition, leading economists, including Nobel laureates, act as research advisers. The partners of McKinsey & Company fund MGI’s research; it is not commissioned by any business, government, or other institution.
