Choosing a human resources consultant
Human resources consultancies have become invaluable to businesses looking for improvements and efficiencies in their operations. This unit explores the issues surrounding how you might go about selecting and using a consultant, examining the risks involved in the venture, fitting the consultant to the task, setting fees and evaluating work. If you are in business and looking to hire a consultant, are a consultant yourself or are studying business at masters level this unit will be useful to you
Predicting the Behaviour of Techno-Social Systems: How Informatics and Computing Help to Fight Off G
We live in an increasingly interconnected world of 'techno-social' systems, where infrastructures composed of different technological layers are interoperating within the social component that drives their use and development. The multi-scale nature and complexity of these networks are crucial features in understanding and managing them. In the last decade advances in performance in computer technology, data acquisition and complex networks theory allow the generation of sophisticated simulation
Integrated safety, health and environmental management: An introduction
Life is full of risk. In this unit ‘risk’ describes the probability and consequences of harm or, at worst, disaster. Risk management involves many stakeholders and integrated management systems help to ensure that safety, quality, environmental and business risks are all managed correctly. This unit also looks at emergency preparedness, that is, the management of emergencies and disasters.
Blueprint for a Safer Planet
Professor Lord Nicholas Stern, a world renowned economist and leading authority on climate change, came to the 21st Century School on Thursday 7 May to give a lecture about his "Blueprint for a Safer Planet".

Lord Stern made headlines in 2006 with the publication of the influential Stern Re
Geoengineering the climate
Geoengineering the climate: Science, Governance and Uncertainty: The Royal Society Study - John Shepherd (NOCS) The climate change we are experiencing now is caused by an increase in greenhouse gases due to human activities, including burning fossil fuels, agriculture and deforestation. There is now widespread belief that a global warming of greater than 2C above pre-industrial levels would be dangerous and should therefore be avoided. However, despite growing concerns over climate change, gl
Climate change and marine ecosystems: have dangerous changes already begun?
Special seminar from the James Martin 21st Century School: Climate change and marine ecosystems: have dangerous changes already begun? The Earth's ocean is central to the conditions experienced on our planet, regulating its atmosphere, climate and biology. Recent evidence, however, suggests that the physical and chemical conditions within the ocean are changing in ways that are rapidly moving outside those experienced for millions of years with major changes to ocean temperature, acidity, sea ic
Stability and Complexity in Model Banking Systems
The recent banking crises have made it clear that increasingly complex strategies for managing risk in individual banks and investment funds (pension funds, etc) has not been matched by corresponding attention to overall systemic risks. Simple mathematical caricatures of 'banking ecosystems', which capture some of the essential dynamics and which have some parallels (along with significant differences) with earlier work on stability and complexity in ecological food webs, have interesting implic

Those Golden Eggs Come From Somewhere: Internet Regulation at a Crossroads
A discussion of how largely well-intentioned political and legal reactions to the highest-profile risks of ICT creates a danger of perhaps killing the goose that is giving us golden eggs of innovation, decentralization, and personal empowerment. From its inception, many have recognized the Internet's potential as a liberating, decentralizing, and, yes, destabilizing technology but also its counter-potential as a controlling and centralizing technology. Over the last two decades, predictions abo
China U.S. Climate Conference
Opening Session: The University, Scientific Research, and Climate Change
Running Time: 1 hour, 22 minutes
This panel will highlight the mutual vulnerability of China and the U.S. to climate change, and the indispensable role of scientific research in understanding the problem and developing solutions.
What's at Risk? Climate Model Predictions and Physical and Biological Impacts
Running Time: 1 hour, 17 minutes
This panel of climate scientists will describe the state of scientific knowledge rega
Cell Fractionation in Tetrahymena
To illustrate cell fractionation, nuclei are isolated from the ciliated protozoan, Tetrahymena thermophila. A table top clinical centrifuge is used for the fractionation steps and the procedure is monitored microscopically using a differential stain. To determine the efficiency of the procedure, cell and nuclear counts are determined with a hemacytometer. To quantify DNA, the Diphenylamine Reaction is carried out and the amount of DNA per nucleus is calculated.
Benefits of Standardized Diabetes and Hypertension Screening Forms at Community Screening Events
The objectives of this project were to (a) assess hypertension and diabetes screening data collection practices and guidelines and (b) develop and test standardized screening forms for use at minority community- and faith-based screening events. Project Phase I involved resource assessment and the development of a set of screening forms and guidelines containing a core data set for both hypertension and diabetes. These were then tested during Phase II at predetermined communitybased screening ev
Cyanobacteria Health Page
This Centers for Disease Control and Prevention (CDC) Health Studies page focuses on cyanobacteria, single-celled organisms thought to be the origin of plants. Cyanobacteria live in fresh, brackish, or marine water and are of concern to the CDC and Environmental Protection Agency (EPA) because some can form harmful blooms that deplete the oxygen and block sunlight that other organisms need to live. They can also produce powerful toxins that affect the brain and liver of animals and humans. This
The Greenomes site is part of a laboratory- and Internet-based curriculum to bring college students up to the minute with modern plant research. Plant molecular genetic and genomic research still lags behind medically-oriented research on microbes and higher animals. As a result, there are relatively few lab experiences that expose college-level students to the growing insights into plants offered by genomic biology.
Detection of Genetically Modified Foods
Genetically modified foods are often in the news and widely grown in the United States. Three US government agencies (USDA, FDA, and EPA) work to regulate the introduction and production of genetically modified foods. These crops can provide agricultural, ecological and nutritional benefits, but there are also potential risks to the environment and consumers. As consumers and public interest groups around the world have become aware of these risks, there has been a call for more explicit product
Chemiosmotic Principles of Solute Transport in Barley Roots
This exercise will demonstrate to students the fluxes of certain inorganic ions in the roots of barley plants. It will familiarize them with the chemiosmotic principles that are involved in ATP synthesis and give them an understanding of solute transport.
Bacterial Quorum Sensing and Bioluminescence
The bacterium Vibrio fischeri produces light when it is growing symbiotically in the light organ of certain fish and squid species. The bacteria sense they are in a light organ because they are present at a high bacterial cell density, which they detect through "quorum sensing." We use several bacterial strains, each of which carry only part of the genes responsible for the quorum sensing and bioluminescence process. We use chemical and genetic complementation to determine which genes are lackin
