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.

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 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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

List down the epidemiological statistics of old
age persons
Explain the theories of aging
6. OLD AGE Classification
It is the last stage in the life

Old old : 85 years and older.
9. Biological theories
Genetic Theory
Wear-and-Tear Theory
Environmental Theory
Immunity Theory
Neuroendocrine Theory
Physical process of aging,
including molecular and
cellular changes in the
major organ systems and
the body’s ability to
function adequately and
resist disease.
10. 1) Genetic Theory
• According to genetic theory,
aging is an involuntarily
inherited process that
operates over time to alter
cellular or tissue structures.
• This theory suggests that life
span and longevity changes
are predetermined.
11. 2) Wear-and-Tear Theory
• Body is similar to a machine, which loses function when its
parts wear out.
• As people age, their cells, tissues and organs are damaged by
internal or external stressors.
• The effects of aging are caused by progressive damage to
cells and body systems over time. Essentially, our bodies
"wear out" due to use. Once they wear out, they can no longer
function correctly.
12. • Free radicals, which are the waste
products of metabolism, accumulate
and cause damage to important
biological structures.
• According to this theory, these free
radicals cause DNA damage, cross-
linkage of collagen, and the
accumulation of age pigments

15. 5) Neuroendocrine Theory
• Proposes that changes in hormone production result in
organism’s decline
• When we are young, our hormones work together to regulate
many bodily functions, including our responses to heat and
cold, our life experiences and our sexual activity
• Hormones are vital for repairing and regulating our bodily
functions, and when aging causes a drop in hormone
production, it causes a decline in our body's ability to repair
and regulate itself
17. TYPES OF PSYCHOSOCIAL THEORIES
Personality Theory
Developmental Task Theory
Disengagement Theory
Activity Theory
Continuity Theory
18. 1) PERSONALITY THEORY
• Personality theories address aspects of psychological
growth without delineating specific tasks or
expectations of older adults
• In a classic study by Reichard, Livson, and Peterson
(1962), the personalities of older men were classified
into five major categories according to their patterns of
adjustment to aging
20. 1. Mature men - are considered
well-balanced persons who
maintain close personal
relationships.
2. Rocking chair-
personalities are
found in passive
Disposition.
3. Armored men have well-
integrated defence
mechanisms, which serve as
adequate protection.
21. 4. Angry men are bitter about
life, themselves, and other
people.
5. Self-haters are similar to
angry men, except that most
of their animosity is turned
inward on themselves
22. Mature
Rocking chair
Armored
Healthy
Adjusted individuals
Angry
Self hater
less successful
in aging
23. 2) Developmental Task Theory
•Developmental tasks - The activities and challenges
that one must accomplish at specific stages in life to
achieve successful aging.
•Primary task of old age, as being able to see one’s life
as having been lived with integrity (Erikson (1963)
•Absence of achieving that sense of having lived well,
the older adult is at risk for becoming preoccupied
with feelings of regret or despair.
24. 3) Disengagement Theory
• Engagement means to be involved with
people and activities.
• Disengagement means withdraw from
engagement.
• Older people will need to withdraw from
social contact and will disengage because of
reduced health and loss of social
opportunities.
25. •It is necessary for the proper
functioning of a growing
society.
•The benefit to the older adult is
thought to be in providing time
for reflecting on life
accomplishment .
•The benefit to society is
thought to be an orderly
transfer of power from old to
Young.
26. 4) Activity Theory
The way to age successfully is to stay active.
•Sadock and Sadock suggested that social integration
is the prime factor in determining psychosocial
adaptation in later life.
•This theory holds that the maintenance of activities
is important to most people as a basis for deriving
and sustaining satisfaction, self-esteem and health.
27. 5) Continuity Theory
• The continuity theory of normal aging states that
older adults will usually maintain the same
activities, behaviors, relationships as they did in their
earlier years of life.
• According to this theory, older adults try to maintain
this continuity of lifestyle by adapting strategies that
are connected to their past experiences
28. • The theory deals with the internal structure and the
external structure of continuity to describe how people
adapt to their situation and set their goals.
• The internal structure of an individual such
as personality, ideas, and beliefs remain constant
throughout the life course.
• This provides the individual a way to make future
decisions based on their internal foundation of the past.
• The external structure of an individual such
as relationships and social roles provides a support for
maintaining a stable self-concept and lifestyle.
