Target Earth: The Grand Scale Problems of the 21st Century
At the start of the 21st century, humankind finds itself on a non-sustainable course - a course that, unless it is changed, will lead to catastrophes of awesome consequences. Severe climate change, water shortages, mass famines, global pandemics, global terrorism... All these mega-problems are interrelated and need a long-term view of the future. They are global problems and cannot be solved by one country alone. This could be humanity's last century, or it could be the century in which civiliz
Punxsutawney Groundhog Eve Rhyming Song
A music video about Punxy Phil on the Eve of Groundhog Day. Sing along music for kids. Really cute rhyming song and provides information or questions between each stanza. Students will enjoy watching this on Groundhog's Day. (7:25)
Bottom billion or bottom zero? Policies for international poverty reduction
Some developing countries have achieved rapid economic growth and poverty reduction while others have stagnated. This talk will review the determinants of success and the prospects for lagging regions to improve performance and eliminate poverty. Achieving an end-state of "zero" has emerged as an important policy goal for a number of 21st Century challenges. The most prominent example is the "Global Zero" campaign to eliminate nuclear weapons. Yet, in a century of globalization, when the life of
A New Approach to Nuclear Disarmament: Learning from International Humanitarian Law Success
Achieving an end-state of "zero" has emerged as an important policy goal for a number of 21st Century challenges. The most prominent example is the "Global Zero" campaign to eliminate nuclear weapons. Few issues are more appropriate subjects of humanitarian concern and international humanitarian law than the choice, possession, use and misuse of weapons. A body of International Humanitarian Law (IHL) and Disarmament Treaty Law has been built up over the last century to control and prohibit a ra

Measuring success 3 : the economic impact of six major sports events supported by the world class ev The reports findi
This report was published and made available on the Web by UK Sport in 2005. UK Sport commissioned the Sport Industry Research Centre at Sheffield Hallam University to undertake economic impact studies at six major sports events supported by the National Lottery funded World Class Events Programme. At each event the standard UK Sport methodology was used to calculate the additional expenditure in the host economy which was directly attributable to an event being staged.

ScienceCasts: Fried Planets
Astronomers have caught a red giant star in the act of devouring one of its planets. It could be a preview of what will happen to Earth five billion years from now. (03:32)
A Crisis in Human Rights: Genocide in Darfur and Beyond
Focusing on the crisis in Darfur, the speakers will offer a comprehensive view of how and why a conflict evolves into a full-fledged genocide. The Darfur genocide has involved not just the outright immediate killing of people, but also the creation of conditions that have made life impossible by chasing people out into the desert and destroying their homes, villages, food supplies and livelihoods. Speakers will present eyewitness accounts of events on the ground in Darfur as well as academic res
The Democracy Project [Audio]
Speaker(s): Dr David Graeber, Professor Craig Calhoun | From the earliest meetings for Occupy Wall Street, David Graeber felt that something was different from previous demonstrations. What was it about this particular movement that worked this time? And what can we now do to make our world more democratic again? Graeber presents a vital new exploration of anti-capitalist dissent, looking at the actions of the 99% and revealing the alternative political and economic possibilities of our future.
Transport Processes in the Environment, Fall 2004
Introduction to momentum and scalar transport in environmental flows, with emphasis given to river and lake systems. Derivation and solutions to the differential form of mass conservation equations. Topics include: molecular and turbulent diffusion, boundary layers, dissolution, phase partitioning, bed-water exchange, air-water exchange, settling and coagulation, buoyancy-driven flows, and stratification in lakes.
In some years back the craft upholstery was used to describe the making of carpets, curtains, wall hangings, mattresses and the covering of furniture with fabrics etc. However, with the upsurge of specialization during the industrial revolution, which now dominates the industrial world, the word upholstery is limited to the manufacture and repair of stuffed furniture. The making of curtains and wall hangings has now become a specialized area for interior decorators whilst the production of mattr
Volcanoes are big movers and shakers in the business of continually redesigning the Earth's landscape. With no concern for nearby people or ecosystems, volcanoes release toxic gases, climate-altering ash, lava and rock. How does this work? Are scientists getting better at predicting volcanic eruptions? How do areas recover after destruction?
Twister: the Tornado Story
Tornadoes are capable of serious destruction. What gets them twisting? Where do they get their energy? How can we protect ourselves when a tornado is approaching?
Beginner Modeling Exercises
The goal of this paper written as part of the MIT Systems Dynamics in Education Project is to teach the reader how to distinguish between stocks and flows. A stock is an accumulation that is changed over time by inflows and outflows. The reader will gain intuition about stocks and flow through and extensive list of different examples and will practice modeling simple systems with constant flows. STELLA modeling examples include, but are not restricted to, skunks populations, landfills, a bank ac
Visualizing Cultures opens a window on modern times by wedding popular images and scholarly commentary in ways that were not technologically possible until recently. Focusing to date on Japan and Asia in the modern world, these units enable users to “see” historical moments as they were actually depicted for mass audiences at the time from various national, cultural, racial, ideological, and individual perspectives. The graphics themselves also reflect the evolving nature of different medium
Calculating Molecular Weight
The molecular weight is the mass of one mole of a substance. Usually, the units used for this are grams per mole. In this movie, we show how to calculate the molecular weight of a substance from the atomic weights given on the periodic table. On another page, we use the molecular weight to convert between the macroscopic scale (grams of a substance) and the microscopic scale (number of molecules of that substance).

SAGP Guide to Clinical Medical Practice
Manual originating from personal notes made over many years of semi-rural private and hospital practice in South Africa. A useful resource based on many years of semi-rural private and hospital practice in South Africa involving major trauma, surgery and obstetrics, in addition to the common problems of general practice. I have always felt it very useful to be able to confirm facts and figures at the bedside if needed and this has been the motivation that has taken me over 40 years. This meant
Social Attitudes and Public Opinion
This course examines the nature of attitudes, beliefs, and values, and the influences which indiviudals' attitudes have upon their behavior. Various theories of attitude organization and attitude change are discussed, and the development of social attitudes is explored by examining the differential impact of the family, the educational system, the mass media, and the general social environment. The changing content of public opinion over time and its relationship to the political system are also
