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.
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.

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.

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.

UNIT 4: Materials
This is my presentation of the UNIT 4: Materials.
First of all I’m going to show you the contents:
1. Raw materials
2. Materials
2.1. Different types of materials
3. Manufactured goods
4. Properties of materials
4.1. Physical properties
4.1.1. Explanation (Physical properties)
4.2. Chemical properties
4.3. Ecological properties
4.1.3. Explanation (Ecological properties)
1. Raw materials:
They are substances that are extracted directly from natural objects.
They are classificated into three groups: 1. Raw materials from animal origin
(such as wool). 2. Raw materials from vegetable origin (for example cotton). 3.
Raw materials from mineral origin (like marble).
2. Materials:
They are processed raw materials that are ready for making any type of product.
There are two types of processes: 1. The physical process which consists in to
change the state of a substance, but the chemical composition is the same. 2. The
chemical process that consists in to transform a substance into a different one
with different characteristics. The chemical composition changes, too.
2.1.
Different types of materials:
There are 6 types of materials: wood, metals, plastics, textiles, stone and
ceramics.
2. 3. Manufactured goods:
They are products made by humans to help or satisfy their needs and improve
their standard of living.
4. Properties of materials:
There are three types: 1. Physical properties. 2. Chemical properties. 3.
Ecological properties.
4.1.
Physical properties:
The physical properties are the ones which relate to how materials react to
external stimuli.
Here there’s a scheme with all the physical properties that we studied:
electrical properties (conductivity and insulation), thermal properties
(conductivity: conductors
and
insulator;
expansion
and contraction,
fusibility and welding), acoustic properties (conductivity and insulation),
magnetic properties (magnetism), optical properties (opaque, translucent
and transparent), mechanical properties (mechanical strength: tensile,
flexural, compressive, shear and torsional; elasticity and plasticity,
malleability and ductility, hardness and toughness and brittleness) and
other properties (density, porosity, permeability and impermeability).
4.1.1. Explanation (Physical properties):
Now I’m going to explain you all the physical properties:
Electrical properties: The materials that have electrical conductivity
are the ones that conduct electricity; and the materials that have
electrical insulation are the ones that don’t conduct it.
Thermal properties:
The thermal conductivity is when a material
conducts heat and the insulation is when a material doesn’t conduct
heat. The expansion is when the temperature increases and the
material expands. The contraction is when the temperature decreases
and the material contracts. The fusibility is when a material changes
from solid to liquid when its temperature is increased. Welding is a
property that consists in join together pieces by using heat or
chemicals.
Acoustic properties: The acoustic conductivity is the capacity of
materials to transmit sound; and the acoustic insulator is when a
material doesn’t conduct sound well.
Magnetic properties: The magnetism is the property that has some
metals of attract other metallic materials.
3. Optical properties: The opaque materials doesn’t allow light pass
through them. The translucent materials allow light pass through them,
but the objects behind can’t be seen clearly. The transparent materials
allow light pass through them and the materials can be seen clearly.
Mechanical properties: The mechanical strength: The materials that
have tensile strength resist stretching. The materials that have
flexural strength resist bending or flexing (to curve something). The
materials that have torsional strength resist twisting (to turn
something). The materials that have compressive strength resist
crushing or compressing (to press something). The materials that have
shear strength resist sliding forces (forces de lliscament). Elasticity:
allows the material to return to its original form after a force that has
changed its shape is removed. Plasticity: allows to be permanently
deformed. Malleability: allows a material to be spread into sheets or
films. Materials with this property are malleable. Ductility: allows a
material to be deformed into filaments/wires. Materials with this
characteristic are ductile. Hardness: the materials that are hard are
difficult to scratch. Toughness: the materials that have this property
are difficult to break. Brittleness: the materials that have this
property are easy to break.
Other properties: Density: is the relationship between the mass and
the volume of an object. Porosity: there are materials that can absorb
or expel liquids or gases. Permeability: is the capacity of some
materials to don’t allow liquids to filter through them. The materials
that have this property are permeable. Impermeability: is the opposite,
they don’t allow liquids to filter through them. The materials that have
this property are impermeable or waterproof.
4.2.
Chemical properties:
The chemical properties are the ones that when a material interacts with
other substances the chemical composition changes.
We only learnt one chemical property: Oxidation. It’s when a mineral reacts
with oxygen, the air or water. The brown thing that appears is the rust. To
prevent rusting we coat materials with paint, varnish, etc.
4.3.
Ecological properties:
These are the properties that say how does the material impact on the
environment.
4. Here there’s a scheme with all the different properties: recyclable
materials,
toxic
materials,
biodegradable
materials,
renewable
raw
materials and non-renewable raw materials.
4.3.1. Explanation (Ecological properties)
Now I’m going to explain every property one by one as I did before
with the physical properties.
Recyclable materials: These can be reused. They help conserve natural
resources and avoid the accumulation of waste products.
Toxic materials: These are harmful to the environment.
Biodegradable materials: These materials are decomposed naturally
and don’t cause damage to the environment. They decompose on contact
with cold or hot water).
Renewable raw materials: These raw materials can be regenerated
naturally.
Non-renewable raw materials: These can’t be regenerated and are
going to be sold out (van a esgotar-se).
