Study Debunks Myths About Gender and Math Performance

ScienceDaily (Dec. 12, 2011) — A major study of recent international data on school mathematics performance casts doubt on some common assumptions about gender and math achievement — in particular, the idea that girls and women have less ability due to a difference in biology. the Wisconsin researchers linked differences in math performance to social and cultural factors.

The new study, by Mertz and Jonathan Kane, a professor of mathematical and computer sciences at the University of Wisconsin-Whitewater, was published on Dec. 12, 2011 in Notices of the American Mathematical Society. The study looked at data from 86 countries, which the authors used to test the “greater male variability hypothesis” famously expounded in 2005 by Lawrence Summers, then president of Harvard, as the primary reason for the scarcity of outstanding women mathematicians.

Tropical Sea Temperatures Influence Melting in Antarctica

A photo from the window of a NASA aircraft shows the rift across the Pine Island Glacier ice shelf running off toward the horizon. The plane flew across the crevasse on Oct. 26, 2011 as part of Operation IceBridge, taking detailed measurements of depth, width and shape. The ice shelf has not calved a major iceberg since 2001.

Accelerated melting of two fast-moving outlet glaciers that drain Antarctic ice into the Amundsen Sea Embayment is likely the result, in part, of an increase in sea-surface temperatures in the tropical Pacific Ocean, according to new University of Washington research.Higher-than-normal sea-level pressure north of the Amundsen Sea sets up westerly winds that push surface water away from the glaciers and allow warmer deep water to rise to the surface under the edges of the glaciers, said Eric Steig, a UW professor of Earth and space sciences.

Sustainability CII-ITC Sustainability Awards Ceremony 2011- Recognising and Rewarding Excellence!!

Dear Readers ,Though this blog is not about events but recently CII People requested me to publicize their  Sustainability Awards Ceremony . I found it a good cause so I agreed to do it. 

According to wikipedia ,Sustainability is the capacity to endure. For humans, sustainability is the long-term maintenance of well being, which has environmental, economic, and social dimensions, and encompasses the concept of union, an interdependent relationship and mutual responsible position with all living and non living things on earth. This philosophical interpretation moves well beyond definitions driven by progress oriented economic perspectives that see humans as providing stewardship, the responsible management of resource use. In ecology, sustainability describes how biological systems remain diverse and productive over time, a necessary precondition for human well-being. Long-lived and healthy wetlands and forests are examples of sustainable biological systems.

The word sustainability is derived from the Latin sustinere (tenere, to hold; sus, up). Dictionaries provide more than ten meanings for sustain, the main ones being to “maintain”, “support”, or “endure”.However, since the 1980s sustainability has been used more in the sense of human sustainability on planet Earth and this has resulted in the most widely quoted definition of sustainability and sustainable development, that of the Brundtland Commission of the United Nations on March 20, 1987: “sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

The three pillars of sustainability. Click on ...

At the 2005 World Summit it was noted that this requires the reconciliation of environmental, social and economic demands – the “three pillars” of sustainability. This view has been expressed as an illustration using three overlapping ellipses indicating that the three pillars of sustainability are not mutually exclusive and can be mutually reinforcing. The three pillars – or the ‘triple bottom line‘ – have served as a common ground for numerous sustainability standards and certification systems in recent years, in particular in the food industry. Standards which today explicitly refer to the triple bottom line include Rainforest Alliance, Fairtrade, Utz Certified, and The Common Code for the Coffee Community. The triple bottom line is also recognized by the ISEAL Alliance – the global association for social and environmental standards.

 In India, Centre of Excellence for Sustainable Development , a pioneering effort by CII,tries  to bring ‘Blue’of economy and ‘green’ of sustainability together. It is indeed a daunting task and the organization which are able to do it are commendable.To recognise  the sustainability in businesses brought by their efforts , CII -ITC institued  a series of awards and going to organize an award ceremony. Details are following:

Ceremony Date:4 – 8pm, Friday, December 16, 2011

Venue: Stein Auditorium,India Habitat Centre, New Delhi

A panel of high-level speakers will discuss the rewards of sustainability, and a series of awards will be bestowed upon the participants that demonstrate outstanding achievements in sustainability performance. In addition to four top levels of recognition, theme- and sector-specific recognitions will be presented.

In the last six years, over 400 organisations of various sizes and sectors have vied for the CII-ITC Sustainability Awards. Participants’ triple bottom line performance is evaluated and top performers are identified .

In the last six years, over 400 organisations of various sizes and sectors have vied for the CII-ITC Sustainability Awards.

Special guests will include  Mr. Y C Deveshwar, Past President, CII, Chairman, CII-ITC Centre of Excellence for Sustainable Development Advisory Council, & Chairman, ITC Ltd; Mr. Suresh P Prabhu, Chairman of the CII-ITC Sustainability Awards Jury, & Chairperson, CEEW; CEOs and members of the Sustainability Awards Jury.

India in Likely Global ‘hotspots’ of climate-induced food insecurity

A study has mapped global “hotspots” where climate-induced food insecurity is most likely to happen in the future, and it includes India. The study, ‘Mapping Hotspots of Climate Change and Food Insecurity in the Global Tropics’, was produced by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS).

The work was undertaken by a team of scientists responding to an urgent need to focus climate change adaptation efforts on people and places where the potential for harsher growing conditions poses the gravest threat to food production and food security. The researchers pinpointed areas of intense vulnerability by examining a variety of climate models and indicators of food problems to create a series of detailed maps.

One shows regions around the world at risk of crossing certain “climate thresholds”-such as temperatures too hot for maize or beans-that over the next 40 years could diminish food production.

Another shows regions that may be sensitive to such climate shifts because in general they have large areas of land devoted to crop and livestock production. And finally, scientists produced maps of regions with a long history of food insecurity.
