Fossil fuels like coal and gas have been heavily used by humankind, changing the atmosphere and global temperatures. However, fossil fuels are non-renewable and their use produces toxins and plastic pollution. The document discusses alternatives like solar and hydroelectric energy which do not have the same disadvantages as fossil fuels. Solar energy can be generated from sunlight but is limited by weather, while hydroelectric plants are expensive to build and can damage habitats. In conclusion, alternative renewable sources should be used more to protect the planet since fossil fuels will eventually be depleted.
Humankind is responsible for the massive USE of fossil fuels which has changed the atmosphere and temperature of the planet. Toxins and plastic are an accumulating problem of the oceans, land and air, while technology is becoming our second if not OUR first nature. Discuss.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
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.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
1. Fossil Fuels
Humankind is responsible for the massive use
of fossil fuels which has changed the
atmosphere and temperature of the planet.
Toxins and plastic are an accumulating
problem of the oceans , land and air, while
technology is becoming our second if not our
first nature.Discuss

• What are the fossil fuels (p3)
• What is the use of fossil fuels (p4)
• Advantages (p 5,6)
• Disadvantages (p 7,8)
• Alternatives (p9-17)
• Conclusion (p18)
3. Fossil fuels
• Fossil fuels are fuels such as coal and gas formed
by geological changes. They were formed in
millions of years when living organism and
plants were buried in the soil or because of
earthquakes and the pressure of high
temperatures of the earth’s layers.
https://en.wikipedia.org/wiki/Fossil_fuel
4. Use of fossil fuels
• Fossil fuels are used to produce plastics,
medicines, cosmetics and much more. Factories
also use them as raw material to generate
electricity. In addition fossil fuels are processed
to make gas in order to move our cars.
• https://en.wikipedia.org/wiki/Fossil_fuel
5. Advantages in the use o fossil fuels
• People consume fossil fuels at an incredible rate.
They are a man’s— best friend.
• The main reason for this consumption is their
capacity to generate huge amounts of electricity
• They are very easy to discover
• They are also really easy to transport
• Factories can be constructed in any location
6. • Fossil fuels are inexpensive, especially coal
• Due to their stability and consistency we can
store them for a long time

7. Disadvantages in the use of fossil fuels
• Fossil fuels are known to be harmful for our
planet as the toxic they produce is the main
reason of global warming
• They are non renewable sources. Fossil fuels
cant be exhausted and they are not abundant
8. The ozone layer that protect us from UV rays is
getting destroyed by the toxic carbon dioxide
9. Alternative ways
• We can admit that the consequences are more
than many! That is why humans have found a lot
of alternative ways that can have the same use as
fossil fuels:
• Solar Energy
• Hydroelectric Energy
10. Solar energy
For sure the sunlight is plenty on our planet. But
is it possible to replace fossil fuels?
Sunlight converts into electricity either by using
photovoltaics or by using concentrated solar
power.
https://en.wikipedia.org/wiki/Solar_power
11. Advantages of solar energy
• Solar energy is a resource that is not only
sustainable for energy consumption, it is
indefinitely available. Solar power can be used to
generate electricity, it is also used in simple
technology to heat water (solar water heaters).
• Solar panels also require little maintenance
12. Disadvantages of solar power
• The primary disadvantage of solar power is that
it is not available during the night. The power
generated is also reduced due to bad weather
conditions, so there is no energy on a cloudy day
• Solar panels can not be made in any location and
they can be very expensive.
http://www.seia.org/about/solar-energy
14. Hydroelectric Power
• Hydroelectric power is electricity generated by
hydropower. Hydropower is applied through the
gravitational force of falling or flowing water.
Electricity is created when the water is passed
over large mechanical turbines, the water
pressure forces the turbines to turn, the
mechanical energy created is then turned into
electricity.
15. Advantages of hydroelectric power
Hydroelectricity does not "use" water, all of the
water is returned to its source of origin.
Hydroelectric power can be created all year long, as
long as the body of water it is using never runs dry.
It is also another absolutely clean source of energy.
The power plants, once in place, do not create any
waste byproducts in their conversion.
16. Disadvantages of hydroelectric power
• Like all power plants, hydroelectric plants are very
expensive to build, and must be built to a very high
standard. The high cost means that plants must be
used for a long time to become profitable. It can also
create flooding of land, which means natural
environment and the natural habitat of animals, and
even people, may be destroyed.
• They can’t be built in any location
https://en.wikipedia.org/wiki/Hydroelectricity
17.
18. Conclusion
After all I firmly believe that human beings
ought to respect their planet, and alternative
ways must be used more often because fossil
fuels will soon run out!
19. Thank you for your
attention!
