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.
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.

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
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.

2. What is Arrays ?
• An array is a group of consective memory locations with same name and data
type.
• Simple variable is a single memory location with unique name and a type. But
an Array is collection of different adjacent memory locations. All these
memory locations have one collective name and type.
• The memory locations in the array are known as elements of array. The total
number of elements in the array is called length.
• The elements of array is accessed with reference to its position in array, that is
call index or subscript.
3. Advantages / Uses of Arrays
Arrays can store a large number of value with single name.
Arrays are used to process many value easily and quickly.
The values stored in an array can be sorted easily.
The search process can be applied on arrays easily.
5. One-D Array
A type of array in which all elements are arranged in the form of a list is
known as 1-D array or single dimensional array or linear list.
Declaring 1-D Array:
data_type identifier[length]; e.g: int marks[5];
o Data _type: Data type of values to be stored in the array.
o Identifier: Name of the array.
o Length: Number of elements. 0 1
2 3 4
int marks
6. One-D array Intialization
The process of assigning values to array elements at the time of array
declaration is called array initialization.
Syntax:
data_type identifier[length]={ List of values }; e.g: int marks[5]={70,54,82,96,49};
o Data _type: Data type of values to be stored in the array.
o Identifier: Name of the array.
o Length: Number of elements
o List of values: Values to initialize the array. Initializing values must be constant
70 54 82 96 49
7. Accessing element of array
Individual Element:
Array_name[index];
Using Loop:
int marks[5];
for(int i=0;i<=4;i++)
marks[i]=i;
8. Searching In Array
Searching is a process of finding the required data in the array. Searching
becomes more important when the length of the array is very large.
There are two techniques to searching elements in array as follows:
Sequential search
Binary search
9. Sequential Search
Sequential search is also known as linear or serial search. It follows the
following step to search a value in array.
Visit the first element of array and compare its value with required value.
If the value of array matches with the desired value, the search is complete.
If the value of array does not match, move to next element an repeat same
process.
10. Binary Search
Binary search is a quicker method of searching for value in the array. Binary
search is very quick but it can only search an sorted array. It cannot be
applied on an unsorted array.
o It locates the middle element of array and compare with desired number.
o If they are equal, search is successful and the index of middle element is
returned.
o If they are not equal, it reduces the search to half of the array.
o If the search number is less than the middle element, it searches the first half of
array.
Otherwise it searches the second half of the array. The process continues until
the required number is found or loop completes without successful search.
11. Sorting Arrays
Sorting is a process of arranging the value of array in a particular order.
An array can be sorted in two order.
o Ascending Order
o Descending Order 12 25 33 37 48
48 37 33 25 12
12. Techniques Of Sorting Array
There are two techniques of sorting array:
o Selection Sort
o Bubble Sort
13. Selection Sort
Selection sort is a technique that sort an array. It selects an element in the
array and moves it to its proper position. Selection sort works as follows:
1. Find the minimum value in the list.
2. Swap it with value in the first position.
3. Sort the remainder of the list excluding the first value.
14. Bubble Sort
Bubble Sort is also known as exchange sort. It repeatedly visits
the array and compares two items at a time. It works as follows:
o Compare adjacent element. If the first is greater than the second,
swap them.
o Repeat this for each pair of adjacent element, starting with the first
two and ending with the last two. (at this point last element should
be greatest).
o Repeat the step for all elements except the last one.
o Keep repeating for one fewer element each time until there are no
pairs to compare.
15. Two-D Arrays
Two-D array can be considered as table that consists of rows and
columns. Each element in 2-D array is refered with the help of two
indexes. One index indicates row and second indicates the column.
Declaring 2-D Array:
Data_type Identifier[row][column];
e.g: int arr[4][3];
o Data _type: Data type of values to be stored in the array.
o Identifier: Name of the array.
o Rows : # of Rows in the table of array.
o Column : # of Columns in the table of array.
0,0 0,1 0,2
1,0 1,1 1,2
2,0 2,1 2,2
3,0 3,1 3,2
16. Two-D array Intialization
The two-D array can also be initialized at the time of declaration.
Initialization is performed by assigning the initial values in braces
seperated by commas.
Some important points :
o The elements of each row are enclosed within braces and seperated by
comma.
o All rows are enclosed within braces.
o For number arrays, if all elements are not specified , the un specified
elements are initialized by zero.
