Special emphasis is placed on the emergence of mass media as a
Amphibians May Give Us Clues to Our Changing Climate
Changes in amphibian populations may offer clues to changes in our climate. In the Rock Mountains scientists spend their summers studying wind, weather, plant life and amphibians. The salamander population in this area fluctuates year to year and they are trying to determine if this decline is caused by global warming or humans. Run time 03:14.

Legal Controversy on the Telly - Glen Del Medico
Glen Del Medico, who is now retired, was the BBC’s chief programme legal adviser and worked for the corporation for nearly 40 years. In his time he’s dealt with almost every legal controversy the BBC has been faced with and says on the Hutton Inquiry, that he would have cleared Andrew Gilligan’s story about the dossier on Iraqi weapons for broadcast if he had been consulted on it. Hear him speaking to students on matters of media law.

Sustainable Urban Systems to Transfer Achievable Implementation Network (SUSTAIN)
The main aim of SUSTAIN is to develop collaborative research proposals to investigate how to improve the development of sustainable cities. This will be achieved by convening a series of 4 workshops; water, energy, synergy and transport, each consisting of two meetings and each pair developing one (or more) collaborative proposals. In August 2005, Arup- one of the world’s most respected global design consultatncies - was contracted to design and masterplan the world’s first sustainable city
Genesis Chapter 47 - New International Version of the Bible
This video contains a high quality narration of The Book of Genesis, Chapter 47, from the New International Version of the Bible. Scriptures read by professional voice actors, along with good music and sound effects. No moving images.
17.951 Nuclear Weapons in International Politics: Past, Present and Future (MIT)
This course will expose students to tools and methods of analysis for use in assessing the challenges and dangers associated with nuclear weapons in international politics. The first two weeks of the course will look at the technology and design of nuclear weapons and their means of production. The next five weeks will look at the role they played in the Cold War, the organizations that managed them, the technologies that were developed to deliver them, and the methods used to analyze nuclear fo
Organise production processes
This unit covers the competency to organise, using all available information and resources, the production of mass-produced and customised fittings, equipment and assemblies in the furnishing industry. It is anticipated that this unit will be undertaken in conjunction with LMFFT4010A Identify and calculate production costs; by tradespeople wanting to upskill from a relevant Certificate III furnishing qualification to become production managers, factory managers or business owners.
Doing the right thing : corporate social responsibility in a global marketplace
Globalisation, mass consumer awareness and public accountability are all factors in persuading companies to adopt ethical policies. As companies become more accountable not only for their own actions but for those within their supply chain, they have to adapt to ensure success within the context of the global society they operate in. Professor Jeremy Moon (Professor of Corporate Social Responsibility at the University of Nottingham Business School and Director of the International Centre for Cor
Physics in architecture
Developed in 1998 by Dr John Whittle (Department of the Built Environment) using Authorware, this package contains brief interactive notes on eight areas of physics in which architects need a working knowledge. However, it is also useful to others in science, engineering and social sciences looking for an introduction to the topics concerned. These topics are: Units of measurement; Scalar and vector quantities; Newton’s laws; Mass and weight; Action and reaction; Waves; Heat, work and energy;
22.251 Systems Analysis of the Nuclear Fuel Cycle (MIT)
This course provides an in-depth technical and policy analysis of various options for the nuclear fuel cycle. Topics include uranium supply, enrichment fuel fabrication, in-core physics and fuel management of uranium, thorium and other fuel types, reprocessing and waste disposal. Also covered are the principles of fuel cycle economics and the applied reactor physics of both contemporary and proposed thermal and fast reactors. Nonproliferation aspects, disposal of excess weapons plutonium, and tr
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
Assessing the Biological Weapons and Bioterrorism Threat
BIOSECURITY FOR A NEW ERA Lecture Series Biological weapons (BW) have been a significant national security preoccupation for nearly 15 years. The events of September 11 and the anthrax attacks that followed have magnified these concerns by orders of magnitude while shifting the context almost entirely to "bioterrorism." Over the past four years, the federal government has spent nearly $30 billion to counter the anticipated threat. Strangely, these responses took place in the absence of virtuall
NASA CONNECT Better Health from Space to Earth
In NASA CONNECT Better Health From Space to Earth, students will learn about the importance of good nutrition and exercise. They will investigate what we can learn in space about our bodies here on Earth. Students will see how researchers and scientists apply the mathematics concepts of measurement and estimation to study the loss of calcium in bones and the loss of muscle mass while astronauts are living and working in space. Grades 6-8.
Exploring the Table of Isotopes
The following information will help you understand the Periodic Table of the Isotopes. Elements: Each element has a fixed number of positively charged protons in its nucleus and an equal number of electrons orbiting the nucleus. For example, hydrogen (H) has one proton and one electron, but lead (Pb) has 82 protons and 82 electrons. There are about 115 known elements of which 82 are naturally abundant. Isotopes: The nucleus contains both protons and neutrons. An element has a fixed number of
The Gold Rush, positive for California in so many ways, had a devastating effect on the state's environment. Many of these problems were directly related to gold-mining technology. The process of hydraulic mining, which became popular in the 1850s, caused irreparable environmental destruction. Two images show California's largest hydraulic mine ? Malakoff Diggings, in Nevada County ? in action. (Malakoff Diggings is now a state park and open to visitors.) Dams (such as the English Dam in Nevada
By the late 1960s, despite the ongoing Civil Rights movement, frustration over poverty, discrimination, injustice, and high unemployment among African Americans helped fuel unrest in many poor, black urban areas. On August 11, 1965, sparked by an angry confrontation between a white police officer and an African American motorcyclist, the Watts neighborhood in Los Angeles erupted in a large-scale civil disorder that lasted for six days and became known as the Watts Riots. Thirty-four people were
Dilemmas and Debates in Entrepreneurship
This is a course about dilemmas and debates. A dilemma is "an argument presenting two or more equally conclusive alternatives; a choice or a situation involving choice between equally unsatisfactory alternatives; a problem seemingly incapable of a satisfactory solution". The process of entrepreneurship involves the recognition of challenges and dilemmas, vigorous debate, and ultimately, solutions. No solution lasts long in an entrepreneurial milieu whose underpinning is "creative destruction". Y
