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
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.

3. • The previously used datum system for
measuring lenses was established as
a system of reference points for
frames & lenses so , that placement of
lens optical centers & bifocal
segment heights would be consistent.
• Horizontal lines were drawn at the
highest & lowest edges of the lens.
3
4. A line drawn halfway between the two
horizontal lines & parallel to them was known
as the “ datum line”.
The width of the lens along this line was called
the datum length or eye size.
The point along the datum line halfway
between the edges of the lens is called datum
center.
The depth of lens, measured as the vertical
depth through the datum center, was mid –
datum depth.

8. • Halfway between the top and
bottom of the lens.
• In the datum system this was called
datum line.
• This line referred to as the
horizontal midline or the 180 degree
line.
8
9. GEOMETRIC CENTRE
• The centre of the lens is the point on the
horizontal midline hale way between the two
lens bordering vertical line.
• It is known as the geometric centre or boxing
centre of the edged lens.
• This term does not imply anything about the
optical positioning of the lens.
9
10. SIZE
• The size of the lens then is the length and
depth of the box containing the lens.
• The horizontal length is now commonly
referred to as the eye size when referring to
the frame and the lens size when referring to
the lens.
• Both are measure in millimeter.
10
12. • In determining the horizontal boxing
dimension of a frame that measurement
begins at the inside of the groove on the left
side of the imaginary enclosing box and
extends horizontally across the lens opening
to the farthest part of the groove on the right
side of the box.
12
13. • In measuring a lens, the measurement begins
at the apex, or point, of the bevel on the left
side of the box enclosing the lens and extends
to the apex of the bevel on the right side of
the box.
13
14. EFFECTIVE DIAMETER
• The effective diameter of a lens is found by
doubling the distance from the geometric
centre of the lens to the apex of the lens bevel
farthest from it.
• This measurement helps determine the
smallest lens blank from which the lens can be
cut.
14
16. FRAME DIFFERENCE
• The frame difference between the horizontal
& the vertical measurement is known as the
frame difference.
• It is measure in millimeter.
• Frame difference is sometime referred to as
lens difference.
16
18. DISTANCE B/W LENS OR BRIDGE SIZE
• The DBL is the distance between the two
boxes when both lenses are boxed off in the
frame.
• Bridge size or DBL is measured on the frame
as the distance from the inside nasal eye wire
grooves across the bridge area at the
narrowest point.
• This distance is measured in millimeters.
18
21. GEOMETRIC CENTRE DISTANCE
• The distance between the two geometric
centers of the lenses is known as the
geometric center distance.
• The GCD is also known by three other names:
• 1. Distance between centers (DBC)
• 2. Frame center distance
• 3. Frame PD
21
22. SEG HEIGHT
• When specifying bifocal or trifocal segment
height, the reference points are given in
millimeters as either (l) the distance below or
above the horizontal midline (called seg drop or
seg raise), or (2) the distance from the lower line
of the boxing system rectangle enclosing the lens
shape (called seg height).
• In the actual measuring process , the level of the
lower line of the box corresponds to the lowest
point in the eye wire groove.
22
25. OVER ALL TEMPLE LENGTH
• The overall temple length is the distance from
the center of the center barrel screw hole to
the posterior end of the temple, measured
along the center of the temple.
• Many times the center of the barrel screw
hole will match the position of the butt end of
the temple.
25
27. • Comfort cable temples are measured in terms
of overall length.
• The actual measurement is done by grasping
the tip and extending the temple along the
ruler.
27
34. LENGTH TO BEND
• An older method of measuring temple length
is in terms of the length to bend (LTB).
• This is measured from the center of the barrel
to the middle of the bend.
• The distance from the middle of the temple
bend to the end of the temple is known as the
length of drop.
34
36. FRONT TO BEND
• If the end pieces wrap around in a swept-back
manner, there is a distance between the plane
of the frame front and the actual beginning of
the temple.
• In this case, the temple length could be
specified as frame to bend which would be
slightly longer than LTB.
• This measurement method is seldom used.
36
38. EYE SIZE & DISTANCE B/W LENSES
• When a frame marking such as 50 20is seen,
it means that the eye size is 50 mm and the
distance between lenses is 20 mm.
• The box between the numbers means that the
eye size is measured according to the boxing
method; it also serves to separate the two
numbers and prevent confusion.
• The eye size and DBL are sometimes simply
marked 50-20 or 50/20.
