Building theories: working in a microworld and writing the mathematical notebook
In the framework of a long term teaching experiment we present an Educational
approach based on the use of a dynamic geometry software and a symbolic manipulator.
Here we present the general ideas of the followed approach focusing on how meanings
can originate from phenomenological experience and evolve under the guidance of the
teacher. In particular we will focus on meanings related to the ideas of theory, axiom and
theorem.
Middle School Portal: Math and Science Pathways (MSP2)
This online reading from the Black Inventor Online Museum focuses on Percy Julian. This reading explores the life, education, and experiences of Julian. As a teacher in organic chemistry at DePauw University, he worked with an associate of his from Vienna, Dr. Josef Pikl, on the synthesis of physostigmine, a drug which was used as a treatment for glaucoma. After much work and adversity, Julian was successful and became internationally hailed for his achievement. Julian developed compounds from s
Reading for Philosophical Inquiry
In this introduction to philosophical thinking, we will read some essays specially chosen from four main areas of interest: (1) the philosophy of life, (2) the philosophy of religion, (3) ethics, and (4) metaphysics and theory of knowledge. Although our approach is not comprehensive, it is reasonably representative of some of the more significant areas of philosophical inquiry. The readings are intended to illustrate the interrelations between these subject areas of philosophy and, as well, to p
Discrimination, Distrust, and Racial/Ethnic Disparities in Antiretroviral Therapy Adherence Among a
Objective: Although discriminatory health care experiences and health care provider distrust have been shown to be associated with health care disparities, little is known about their contribution to racial/ethnic disparities in antiretroviral therapy adherence. We therefore sought to assess the extent to which discriminatory health care experiences and health care provider distrust influence treatmentrelated attitudes, beliefs, and self-reported adherence in a national sample of HIV-infected pa
Addressing Health Care Disparities and Increasing Workforce Diversity: The Next Step for the Dental,
The racial/ethnic composition of our nation is projected to change drastically in the coming decades. It is therefore important that the health professions improve their efforts to provide culturally competent care to all patients. We reviewed literature concerning health care disparities and workforce diversity issues—particularly within the oral health field— and provide a synthesis of recommendations to address these issues. This review is highly relevant to both the medical and public he
Overcoming claims of racism in the UKÂ’s psychiatric services
Professor Swaran Singh talks about research which shows that claims of racism in psychiatric services cannot be supported by evidence. He discusses a new study aimed at tackling some of the social factors that make people from an ethnic minority background more likely to suffer psychosis.
Is the 'Rule of Law' Good for Cities?
There is a widespread consensus that, everywhere in the world, urban development has to be based on the rule of law. But what is 'the rule of law'? Does any formal legal system qualify – or must it have specific requirements? If there are specific requirements, who says what they are? Does the rule of law inhibit – or does it encourage – the extent of privatisation of urban space? Does it require the abolition of informal settlements and businesses or allow them? This lecture will investig
Towards a new response to climate change - perspectives from Australia
With its ratification of the Kyoto Protocol in December 2007 and commitment to introduce an emissions trading scheme - the Carbon Pollution Reduction Scheme - in 2010, the Australian Government has taken the opportunity to approach climate change policy from a fresh perspective. Senator Wong will outline the Government's global and domestic policy approach, with particular emphasis on the key role of market-based mechanisms. Penny Wong was appointed Australia's Minister for Climate Change and Wa
Human Security in an Age of Turbulence
Mary Kaldor is a prolific author who has written widely on a range of key issues over the years ranging from the 'Baroque Arsenal' (1982) a study that challenged the logic of militarism and the belief that more weapons meant more security, through to her groundbreaking 'New Wars'(1999) a book that reveals the new forms that organized violence will take in the 21st century. Mary Kaldor today is one of the most influential and respected alternative voices in the field of applied international poli
Tropical Environmental Health
Inadequate water supplies and lack of sanitation facilities represent major hazards to the public health in many parts of the world. In spite of the International Water Supply Decade, (1980-1990) there are more people without facilities approaching minimum standards now than existed at the beginning of the program. Without improvements in these areas, there can be no hope that there will be an overall improvement in the health of the nations which constitute the Third World. Yet appropriate tech
The "Real Space - Cyberspace" Paradigm
In a chain of "real - perceived - imagined space" the computer reduces to a uniform model of only real and imagined space. It cannot undertake man's function or it cannot build the perception model. However, perception assumes physiological perception, psychological estimation and understanding, and emotional ho-experience. For a person the seizing of space during perception is constructing temporary spatial images and their development. The communicative relations of the person with environment
TWC9: CodePlex Facelift, a little Mayhem, Targeting Async, GUIDs and more This week on Channel 9, Dan and Brian discuss the week's top developer news, including:
Open Education for an Open World
In Charles M. Vest’s expansive vision, scientists and engineers around the world are creating a “meta university†as they increasingly share ideas and build on common knowledge. Technology enables this integration of minds, leading us toward “an era better called brain circulation,†he says.
Vest cites evidence of rap
Technologies Changing Communities, Communities Innovating Technology
The best way to help a community help itself, say Dayna Cunningham and Alexa Mills, is to enable its members to find their voices and talk to each other. In several projects in the U.S. and overseas, the two speakers are developing methodologies for enabling communities to express and define themselves, so they may b
A comparison of attitudes
In this unit we shall look more closely at the evidence available to assess the truth of this argument. Were the working people, as opposed to the political leaders, interested in the issue of expansion? Was such interest evident only among certain sections of the community? Was it predominantly an enthusiasm for empire or not? We shall also try to identify some of the reasons underlying the nature of the response. And we shall be interested in how far politicians found it worth their while to â
Engineering a New Attack on Disease
Out of a world population of 6 billion, 57 million people die each year. And while we have gained 20 years in life expectancy since World War 2, diseases like HIV have taken a toll on morbidity in many developing nations. But according to Rick Young, “the global disease burden is much larger than the number of deaths.†Countles
Electronics on Plastic: A Solution to the Energy Challenge, or a Pipe Dream?
As urgency to address climate change mounts, there’s ever greater interest in harnessing the unlimited potential of the sun to replace fossil fuels. This tantalizing prospect has inspired a raft of new scientific ventures, reports Stephen Forrest.
A theoretical field of silicon solar cells that is 1
Whales to Wood, Wood to Coal/Oil- What’s Next?
In 1845, the Dietz Company of New York introduced the sperm oil lantern, which nearly wiped out some whale species. A decade or so later, Dietz began to manufacture lamps using other oils, and gas lighting fixtures, giving whales a reprieve. More than a century has passed, and we’re “about to do it again,†says
8.2 Working with bio-hazardous material (human material, microbiological agents, plant pathogens)
Health, safety and risk assessment are of paramount importance both in the laboratory and the field. This unit will help make you more aware of the hazards and risks involved in laboratory and field-based research work, as well as giving you an overview of the legal requirements attached to this work. The unit discusses issues involved in the handling chemical and biological agents, basic safety procedures and common field-work hazards.
