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.

Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

5. • Any visible or invisible particle or
gas found in the air that is not part
of the original, normal
composition.
6. Air pollution is defined as the presence of
unwanted and undesirable foreign particles and
gases in the air which may have adverse effects on
human beings , plants , vegetation's and important
structures.
Air pollution is of public health concern and can
occur as :
1. Indoor air pollution Micro scale
2.Outdoor air pollution Meso scale
3.Air pollution at global level Macro scale

8. CLASSIFICATION OF AIR POLLUTANTS
I. Classification based on Origin of pollutants:
• Primary air pollutants: Primary air pollutants are those which are directly
emitted from the source into the atmosphere, and remains in the same form in
the atmosphere. For example: Sulphur oxides, Nitrogen oxides, Carbon monoxide,
etc. The air pollutants are emitted by man made sources like, transportation, fuel
combustion, industrial operations, etc.
• Secondary air pollutants: Secondary air pollutants are those which are formed
by chemical reactions among primary pollutants and atmospheric chemical
species. For example: Ozone, Sulphur trioxide, Ketones, etc.
II. Classification based on states of matter:
• Gaseous air pollutants: Gaseous air pollutants are those air pollutants which
are found in the gaseous state at normal temperature and pressure in the
atmosphere. For example: Carbon-monoxide, Carbon-dioxide, Nitrogen oxides,
Sulphur oxides, etc.
9. • Particulate air pollutants : Particulates are finely divided, air borne, solid and liquid
particles, which remain for very longtime in air, in suspension. Depending on their size
and mode of formation, particulate air pollutants are further classified as below:
• Aerosols: These are air borne suspensions of solid or liquid particles smaller than 1
mm size. Example: dust, smoke, mist, fume, etc.
• Dust: It consists of small solid particles (size 1 to 200 micro-meter) and are generated
by material crushing, grinding or blasting.
• Smoke: They are also fine solid particles of size around 0.1 to 1 micro-meter, formed
by the incomplete combustion of organic matter like coal and wood.
• Mist: It consist of liquid droplets of size around 0.1 to 10 micro-meter and formed by
the condensation of vapours in the atmosphere.
• Fog: If the mist is made up of water droplets at high concentration so as to obscure
vision then mist is called as fog.
• Soot: These are the carbon particles impregnated with tar, and released by the
incomplete combustion of carbonaceous materials.
10. • Classification based on presence in environment:
• Indoor air pollutants: The air pollutants which are generated from households
are called indoor air pollutants. For example: Cleaning agents, Pesticides, Paints,
Glues, gases from stoves, etc.
• Outdoor air pollutants: The air pollutants which are generated outside the
buildings are called outdoor air pollutants. For example: Automobile pollutants,
Industrial pollutants, Mining pollutants, etc.
11. Natural : forest fires, pollen, dust
storm, foul gases etc.
Unnatural : man-made; coal,
wood and other fuels used in
cars, homes, and factories for
energy.

Solution for Air pollution:-
28. Air pollution can be controlled by a
thorough understanding of its causes.
Establishment of industries away from the
towns and cities.
Increasing the length of the chyeysmn in
industries.
Growing more plants and trees.
Use of efficient engines in automobiles.
Use of smokeless choola.
Use of petrol without lead (Unleaded petrol)
31. Effluent from various industries, Sewage
containing domestic waster and pesticides
from agricultural lands are finding their way
into water bodies leading to water pollution.
Causes of Water Pollution: Water pollution is
mainly due to the following causes.
32. WATER QUALITY STANDARDS
• THE DEFINITION OF WATER QUALITY DEPENDS
ON THE INTENDED USES OF THE WATER WHICH
MAY BE EITHER HUMAN CONSUMPTION OR IT
MAY BE FOR INDUSTRIES, IRRIGATION, POWER
GENERATION, RECREATION ETC.
• MAIN PARAMETERS WHICH ARE REQUIRED TO BE
TESTED FOR DETERMINING THE QUALITY OF
WATER CAN BE DIVIDED IN TO
• 1. PHYSICAL
• 2.CHEMICAL
• 3. MICROBIOLOGICAL
34. CHEMICAL PARAMETERS
INCLUDES:
• SOLIDS
• HARDNESS
• CHLORIDES
• PH
• DISSOLVED GASES LIKE OXYGEN,
CARBON, DIOXIDE, HYDROGEN, SULPHIDE
• METELS AND OTHER INORGANIC
SUBSTANCE LIKE FLUORIDE, IRON &
MANGANESE, LEASD, ARSENIC, IODIDES,

36. EUTROPHICATION
• DEPENDING UPON THE INCREASING LEVELS OF
PRODUCTIVITY THE WATER BODIES CAN BE
CLASSIFIED IN TO
1. OLIGOTROPHIC:- WATER WITH POOR NUTRIENT
STATUS AND VERY LOW PRODUCTIVITY OF
AQUATIC PLANTS.
2. MASOTROPHIC:- WATER WITH MODERATE
NUTRIENT STATUS AND MODERATE
PRODUCTIVITY OF AQUATIC PLANTS.
3. EUTROPHIC:- WATER WITH RICH NUTRIENT
STATUS AND HIGH PRODUCTIVITY OF AQUATIC
37.
38. • EUTROPHICATION IS A NATURAL PROCESS AND MAY
TAKE THOUSANDS OF YEARS.
• WITH TIME THE NUTRIENT STATUS OF THE WATER
BODIES GRADUALLY INCREASES. WHICH LEADS TO
MORE BIOLOGICAL PRODUCTIVITY AND ALGAE BLOOMS
OCCURS AND WATER BECOMES MURKY. THE LAKE THUS
BECOMES EUTROPHIC.
• A YOUNG LAKE OR A NEWLY FORMED LAKE HAS LOW
NUTRIENT CONTENT AND HAS LOW PLANT
PRODUCTIVITY.
• WITH PASSAGE OF TIME SUCH LAKES ACQUIRES
NUTRIENTS FROM SURFACE RUNOFF FROM
AGRICULTURAL FIELDS, DOMESTIC SEWAGE ETC WHICH

40. • THE INDUSTRIAL WASTES, MUNICIPAL WASTER, RUNOFF
FROM AGRICULTURAL LANDS PROVIDE PLENTY OF
PHOSPHATES, NITRATES AND VARIOUS MINERALS
STIMULATING ALGAL GROWTH.
• DUE TO WHICH THE WATER BODY BECOMES GREEN.
• IN DUE COURSE OF TIME THE ALGAL BLOOM MAY DIE
ABRUPTLY.
• THE DECAYING ORGANIC MATTER CAUSES DEPLETION
OF DO, DESTROYING FISH AND OTHER AQUATIC
SPECIES.
• BAD TASTE, BAD ODOUR IS PRODUCED AND ALSO

43. Industrial pollutants like mercury, chromium,
cadmium and lead are poisonous. They are also
capable of entering the food chains and cause
diseases in man, Mercury is known to cause a disease
called Minimart.
Organ chlorine pesticides like D.D.T. in the
agricultural wastes are non-degradable and move
along the food chains. It may lead to bio
magnification.
Some industrial effluents can cause changes in color,
odor and taste of water in the natural water bodies.
Contamination of water also leads to spread of water
borne diseases such as cholera, amoebiasis and other
diseases.
44. • Encourage your
family to walk more
• Take the school bus
• Reduce the amount
of spray bottles
• Do not burn leaves in
your yard- put them
in a compost
• Keep your family
cars in tune
• Put catalytic
converters on cars
• Share your room
with others when the
air conditioner is on
• Take care of your
trees
45. •Keep lakes clean
•Take your used motor oil to a drop off place
•Use latex paint instead of oil and rinse your brushes
in the sink rather than the yard
•Fill a spray bottle with soapy water instead of bug
spray
•Plant trees to prevent soil erosion
•Keep litter, pet waste, leaves, and grass clippings out
of gutters and storm drains.

47. WHAT IS NOISE POLLUTION?
Sound that is unwanted or disrupts one’s quality of life is
called as noise. When there is lot of noise in the environment,
it is termed as noise pollution.
Sound becomes undesirable when it disturbs the normal
activities such as working, sleeping, and during conversations.
It is an underrated environmental problem because of the fact
that we can’t see, smell, or taste it.
World Health Organization stated that “Noise must be
recognized as a major threat to human well-being”
48. The nature of sound
• Sound, a manifestation of vibration, travels in wave patterns
through solids, liquids and gases.
• The waves, caused by vibration of the molecules, follow sine
functions, typified by the amplitude and wavelength (or frequency)
• Sound waves of equal
amplitude with
increasing frequency
from top to bottom
49. Sound and human hearing
People generally hear sounds
between the “threshold of hearing”
and the “threshold of pain”
In terms of pressure,
this is 20 μPa – 100 Pa
The decibel scale was developed from this fact
and makes numbers more manageable
The decibel scale generally ranges from
approximately 0 to 130
50. Health Effects
• According to the USEPA, there are direct links between
noise and health. Also, noise pollution adversely affects
the lives of millions of people.
• Noise pollution can damage physiological and
psychological health.
• High blood pressure, stress related illness, sleep
disruption, hearing loss, and productivity loss are the
problems related to noise pollution.
• It can also cause memory loss, severe depression, and
panic attacks.
51. SOURCES OF NOISE POLLUTION
• Transportation systems are the main source of noise pollution
in urban areas.
• Construction of buildings, highways, and streets cause a lot of
noise, due to the usage of air compressors, bulldozers,
loaders, dump trucks, and pavement breakers.
• Industrial noise also adds to the already unfavorable state of
noise pollution.
• Loud speakers, plumbing, boilers, generators, air conditioners,
fans, and vacuum cleaners add to the existing noise pollution.
53. SOLUTIONS FOR NOISE POLLUTION
• Planting bushes and trees in and around sound generating sources is an
effective solution for noise pollution.
• Regular servicing and tuning of automobiles can effectively reduce the noise
pollution.
• Buildings can be designed with suitable noise absorbing material for the
walls, windows, and ceilings.
• Workers should be provided with equipments such as ear plugs and earmuffs
for hearing protection.
54. • Similar to automobiles, lubrication of the machinery and
servicing should be done to minimize noise generation.
• Soundproof doors and windows can be installed to block
unwanted noise from outside.
• Regulations should be imposed to restrict the usage of play
loudspeakers in crowded areas and public places.
• Factories and industries should be located far from the
residential areas.
