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.
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.
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

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.

Planning the Database
It is important to plan how the logical storage structure of the database will affect system performance and various database management operations. For example, before creating any tablespaces for your database, you should know how many data files will make up the tablespace, what type of information will be stored in each tablespace, and on which disk drives the data files will be physically stored. When planning the overall logical storage of the database structure, take into account the effects that this structure will have when the database is actually created and running. You may have database objects that have special storage requirements due to type or size.
In distributed database environments, this planning stage is extremely important. The physical location of frequently accessed data dramatically affects application performance.
During the planning stage, develop a backup strategy for the database. You can alter the logical storage structure or design of the database to improve backup efficiency. Backup strategies are introduced in a later lesson.
These are the types of questions and considerations, which you will encounter as a DBA, and this course (in its entirety) is designed to help you answer them.
Databases: Examples
Different types of databases have their own specific instance and storage requirements. Your Oracle database software includes templates for the creation of these different types of databases. Characteristics of these examples are the following:
Data Warehouse: Store data for long periods and retrieve them in read operations.
Transaction Processing: Accommodate many, but usually small, transactions.
General Purpose: Work with transactions and store them for a medium length of time.

Database Configuration Assistant (DBCA)
You can use the Database Configuration Assistant (DBCA) to create, change the configuration of, or delete a database. You can also create a database from a list of predefined templates or use an existing database as a sample to create a new database or template. This is sometimes referred to as “database cloning.”
You can invoke the DBCA by performing the following steps:
1.Log on to your computer as a member of the administrative group that is authorized to install the Oracle software.
2.If required, set environment variables.
3.Enter dbca to invoke the DBCA.
4.Click Next to continue.
DBCA offers you a choice of assisting with several operations, for example, creating a database.
Oracle Database 10g: Administration Workshop I 3-<number>
Using the DBCA to Create a Database
You can use the DBCA to create a database as follows:
1.Select Create a Database on the DBCA Operations page to invoke a wizard that enables you to configure and create a database.
The wizard prompts you to provide configuration information as outlined in the steps that follow. On most pages, the wizard provides a default setting that you can accept.
2.Select the type of database template to be used in creating the database. There are templates for Data Warehouse, General Purpose, and Transaction Processing databases that copy a preconfigured database, including data files. These data files include control files, redo log files, and data files for various included tablespaces. Click Show Details to see the configuration for each type of database.
For more complex environments, you may want to select the Custom Database option.
Oracle Database 10g: Administration Workshop I 3-<number>
Using the DBCA to Create a Database (continued)
3.Database Identification: Enter the Global Database Name in the form database_name.domain_name, and the system identifier (SID). The SID defaults to the database name and uniquely identifies the instance associated with the database.
4.Management Options: Use this page to set up your database so that it can be managed with Oracle Enterprise Manager. Select the default: Configure the Database with Enterprise Manager.
Oracle Database 10g: Administration Workshop I 3-<number>
Using the DBCA to Create a Database (continued)
5.Database Credentials: Use this page to specify the passwords for the administrative accounts, such as SYS and SYSTEM. In class, use oracle as password for all administrative accounts.
6.Storage Options: Specify the type of storage mechanism (such as File System) that you would want your database to use.
7.Database File Locations: Choose according to your needs. Oracle Managed Files (OMF) eliminate the need for you to directly manage the operating system files comprising an Oracle database. You specify operations in terms of database objects rather than file names. For more details, see the lesson titled “Managing Database Storage Structures.”
Oracle Database 10g: Administration Workshop I 3-<number>
Using the DBCA to Create a Database (continued)
8.Recovery Configuration: If required, specify a flash recovery area and enable archiving.
9.Database Content: These pages provide options for selecting components, such as Sample Schemas, and for using custom scripts.
Oracle Database 10g: Administration Workshop I 3-<number>
Using the DBCA to Create a Database (continued)
10.Initialization Parameters: The tabs on this page provide access to pages that enable you to change default initialization parameter settings:
Memory: Use this page to set the initialization parameters that control memory usage. Use either (A) Typical or (B) Custom memory allocation.
Sizing: To specify block size, enter the size in bytes or accept the default.
Character Sets: Use this page to specify the character sets for your database.
Best Practice Tip: Oracle recommends (whenever possible) that you use Unicode for a database character set because it provides optimal flexibility for supporting Web technologies as well as many spoken languages.
Connection Mode: Select Dedicated or Shared Server Mode. For more details, see the lesson titled “Configuring the Oracle Network Environment.”
Note: Several initialization parameters are set for the lifetime of a database, such as the DB_BLOCK_SIZE and CHARACTER_SET parameters.
Oracle Database 10g: Administration Workshop I 3-<number>
Using the DBCA to Create a Database (continued)
11.Database Storage: If you have selected one of the preconfigured templates for a database, then you cannot add or remove control files or data files.
Note: You may want to save your database definition as an HTML file for easy reference.
12.Creation Options: You have the options of creating your database at this time, saving the database definition as a template, and generating scripts. If you choose all options, then the DBCA first saves the database template, then generates the scripts into your destination directory, and finally creates your database.
Password Management
After the DBCA finishes, note the following information for future reference:
Location of installation log files (see A)
Global database name (see B)
System identifier (SID) (see B)
Server parameter file name and location (see B)
Enterprise Manager URL (see C)
Click Password Management to unlock database accounts that you plan to use. Provide a password when you unlock an account.
Creating a Database Design Template
A template is a predefined database definition that you use as a starting point for a new database. If you do not create a template as part of the database creation process, you can do it anytime by invoking the DBCA. You have three ways to create a template:
From an existing template
From an existing database (structure only)
From an existing database (structure as well as data)
The DBCA guides you through the steps to create a database design template.
Using the DBCA to Delete a Database
To delete (or configure) a database in UNIX or Linux, you must set ORACLE_SID in the shell from which DBCA is launched. Start the DBCA by entering dbca in a terminal window, and click Next on the Welcome page. To delete the database, perform the following steps:
1.On the Operations page, select Delete a Database, and click Next.
2.Select the database that you want to delete (in class, hist), and click Finish.
3.Click Yes to confirm your deletion.
Oracle Database 10g: Administration Workshop I 3-<number>
Using the DBCA to Delete a Database (continued)
Dropping a database involves removing its data files, redo log files, control files, and initialization parameter files. The DROP DATABASE statement deletes all control files and all other database files listed in the control file. To use the DROP DATABASE statement successfully, all the following conditions must apply:
The database must be mounted and closed.
The database must be mounted exclusively—not in shared mode.
The database must be mounted as RESTRICTED.
An example of this statement is:
DROP DATABASE;
The DROP DATABASE statement has no effect on archived log files nor does it have any effect on copies or backups of the database. It is best to use Recovery Manager (RMAN) to delete such files. If the database is on raw disks, then the actual raw disk special files are not deleted.
