We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Growing Interdependence of the Internet and Climate Change

2. Abstract
Greenhouse gas (GHG) emissions continue their relentless rise, even though the global
CO2 level is already considerably higher than it has been on earth for over two million
years. The Information and Communication Technology (ICT) industry currently
produces ~2-3 % of global GHG emissions and will nearly triple, in a business as usual
scenario, from 2002 to 2020. On the other hand, the Climate Group estimates that
transformative application of ICT to electricity grids, logistic chains, intelligent
transportation and building infrastructure, and other social systems can reduce global
GHG emissions by ~15%, five times ICT's own footprint! I will discuss three campus
testbeds for exploring these complex tradeoffs. The first testbed is the NSF-funded
GreenLight Project deployed at UCSD, which creates an instrumented data center that
can guide users who wish to lower the energy cost of computation and storage. The
second testbed is the campus itself, in which the move to centralized computing and
storage can greatly reduce the GHG emissions of the current distributed set of clusters
and storage. The third testbed is the global set of dedicated optical networks (operating
at 10,000 Mbps), coupled to large tiled wall OptIPortals (with fractions of a billion pixels)
and high definition (2 Mpixel/frame) or digital cinema (8Mpixel/frame), to create next
generation "telepresence" systems for "sewing remote rooms together" as a way to
reduce the need for transportation for national or global collaboration.
3. ICT Could be a Key Factor
in Reducing the Rate of Climate Change
Applications of ICT
could enable emissions reductions
of 15% of business-as-usual emissions.
But it must keep its own growing footprint in check
and overcome a number of hurdles
if it expects to deliver on this potential.

7. Global Climatic Disruption Example:
The Arctic Sea Ice
―A pervasive cooling of the Arctic in progress 2000 years ago continued
through the Middle Ages and into the Little Ice Age. It was reversed during
the 20th century, with four of the five warmest decades of
our 2000-year-long reconstruction occurring between 1950 and 2000. The most
recent 10-year interval (1999–2008) was the warmest of the past 200 decades.‖
Mean of all records transformed to summer temperature anomaly
relative to the 1961–1990 reference period, with first-order linear trend
for all records through 1900 with 2 standard deviations

27. Application of ICT Can Lead to a 5-Fold Greater
Decrease in GHGs Than its Own Carbon Footprint
While the sector plans to significantly step up
the energy efficiency of its products and services,
ICT’s largest influence will be by enabling
energy efficiencies in other sectors, an opportunity
that could deliver carbon savings five times larger than
the total emissions from the entire ICT sector in 2020.
