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.

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

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.

2. • Specifications are the written requirements
for a material, product, or service for a
proposed project, like a building, bridge or
machine.
• For architectural projects, the specifications
are art of the Contract Documents included
with the bidding and construction
requirements and the drawings.
• This guide/lesson will cover
– how to organize specifications,
– the types of specification
– methods of specification
– specific type of language used for writing
specifications.
– Few Examples.
3. Purpose of Specifications
• Specifications should describe the type and quality of
every product required for the project.
• The specifications should describe the requirements for
fabrication, erection, application, installation and
finishing.
• Specifications should describe the quality of
workmanship necessary for the project. This includes
– All phases of creation and installation starting with
• manufacturing,
• fabrication,
• application,
• installation,
• finishing and adjustment.
4. • Specifications should include any necessary
codes and standards applicable to the project.
• The specifications should also include
descriptions and procedures for alternate
materials, products or services if necessary.
The specification and project manual.
• Contract Documents contain the bidding and
construction requirements, drawings and
specifications.
• The project manual is the bound written portion of
the Contract Documents.
• The project manual is typically organized
according to Master Format.
5. • The project manual contains the following
elements
– Introductory Information
– Bidding Requirements
– Contracting Requirements
– Specifications
– Appendices
• Introductory Information
– Title Page
– Certifications Page
– Table of Contents
– Guide to Use of the Project Manual (used by many
specifiers)
6. • Bidding Requirements
– Bid Solicitation: Advertisement/Invitation to
Bid
– Instructions to Bidders
– Information Available to Bidders
– Bid Forms and Supplements
• Contracting Requirements
– Agreement
– General Conditions of the Contract
– Supplementary Conditions of the Contract
– Bonds and Certificates
7. • Specifications
– Division 01 – General Requirements
– Divisions 02– Technical Specifications
• Appendices
– Appendices are not included in Master Format
but they are useful for including copies of
information, reference documents, existing
conditions, photographs or example forms for
use in administration.
8. Organization of Specifications
• It is important for the specifications section of
the project manual to be arranged in an orderly
and comprehensive format.
• If the section is organized clearly and follows a
defined procedure it is less likely that the
specifier will overlook or forget something.
• It will also help the contractor, estimator,
inspector, or other reviews find information
more easily.
9. Section Format (Specification section format)
• It is a nationally approved, industry-accepted
standard that provides a defined procedure
for organization of the specifications section.
• It provides guideline for the arrangement of
information within the technical section of
specifications.
• The concise orderly method reduces the
chance for omissions or duplication of
information
• and it assists users of the document by
consistently locating similar information in
the same place in each Section.
10. • Section Format has three separate parts:
– Part 1 – General: This section describes
administrative, procedural and temporary
requirements specific to this section of
specifications.
– Part 2 – Products: This section describes, in
detail, the materials, products, equipment,
systems or assemblies to be used in the
project.
– Part 3 – Execution: This section describes, in
detail, any preparatory actions and how the
products shall be incorporated into the
project.
11. Types of Specifications
• There are four methods of specifying. There
is no defined rule for using one method over
another or about combining methods, but
care should be taken to avoid redundancy or
contradictions.
• The four methods are:
– Descriptive
– Performance
– Reference Standard
– Proprietary
12. Descriptive Specifications
• Under this method of specifying the exact
properties of the materials and methods of
installation are described in detail without
using proprietary or manufacturer's names.
• Descriptive specifications are commonly
used for products for which no standards
exist, on projects where using proprietary
names is restricted, and in situations where
the Architect/Engineer want to exercise tight
control over the specified work.
13. • There are five steps for preparing
descriptive specifications:
1. Research available products
2. Research the important features required for
the product.
3. Determine which features to describe in the
specification and which features to show in
the drawings.
4. Describe the important features.
5. Specify quality assurance measures (i.e.
submittals, certifications, testing or
inspection activities)
14. • Advantages to using descriptive
specifications
– Descriptive specifications specify exactly what
the design intends.
– They are applicable to all conditions, methods or
situations of a project.
– They are applicable to all sizes and types of
projects.
– They permit free competition because they do not
restrict the use of specific products or
manufacturers.
• Disadvantages of descriptive specifications:
– They require the specifier to take special care in
describing the design intent in order to achieve
the desired results.
15. – Descriptive specifications tend to take up
more space because they require more
verbiage than other methods.
– They may be more time consuming than other
methods to create and write.
– They are being used less often as more
complete reference standards are being
developed and implemented.
16. Performance Specifications
• Under this method the required end results
are specified along with the criteria by which
the performance will be judged and the
method by which it can be verified.
• The contractor is free to choose the materials
and methods that comply with the
performance specification.
• They are generally used to encourage the use
of new and innovative techniques that may
lead to more economical construction.
• They are also used to supplement other
specification methods.
17. • Advantages to using performance
specifications:
– Only the end result or design intent is
specified, this gives the Contractor flexibility
in selecting and applying products.
– They permit free competition.
– They can be applicable in all types and sizes
of projects.
– Performance specifications delegate the
technical responsibilities to the construction
industry, where the Contractor instead of the
Architecture/Engineering firm is responsible
for the results.
18. • Disadvantages to using performance
specifications:
– They can be time consuming to produce and
may result in long, detailed specifications.
– They are more difficult to enforce than other
methods of specifying.
– They may be too elaborate for simple or
minor projects.
– Performance specifications delegate the
technical responsibilities to the construction
industry, where the Contractor instead of the
Architecture/Engineering firm is responsible
for the results. (This is both an advantage and
disadvantage)
19. • Reference Standard Specifications
– Under this method reference is made to an
established standard defined by associations
very knowledgeable about a certain part or
phase of construction.
– Reference standard specifications are used for
"commodity" products in the marketplace,
where brand names are not important.
20. – Steps for preparing reference standard specifications
are:
1. The standard must be recognized as authoritative by the
industry.
2. The standard must be available to all parties involved in
the project.
3. The specifier must know the standard. Assure that the
standard relates to the current project and does not
present duplicate or conflicting information.
4. Establish a date of the standard.
5. Incorporate the standard correctly into the specifications.
6. Enforce the requirements of the standard
21. • Advantages to using reference standard
specifications:
– The standard is usually widely known and
accepted by the industry.
– They do not limit competition.
– They dramatically shorten the length of
specifications.
• Disadvantages to using reference standard
specifications:
– There may be no appropriate standard to
reference, because standards are written for
the most commonly used and generally
available products.
22. – Standards generally refer to the minimum
requirements.
– The standard may become obsolete or out-of-
date, because of advances and changes in
technology and the creation of new products.
– They require a lot of research and care in use.
– They must be incorporated properly,
including all supplementary information.
23. • Proprietary Specifications
– Under this method the actual brand names,
model numbers and other proprietary
information is specified.
– They are primarily used for private
commercial projects where the Owner knows
what products they want.
– There are two types of proprietary
specifications, closed and open.
24. – The primary difference between the two types
concerns substitutions are,
• Closed
– Closed specifications generally prohibit substitutions.
– One or more products are specified, and no substitutions
will be considered.
• Open
– Open specifications permit substitutions.
– One or more products are specified, but other
manufacturers will be considered.
– It is necessary to specify the criteria the alternate
manufacturers will be judged by.
25. • Advantages to using proprietary
specifications:
– They allow for close control of product
selection.
– The drawings can be more complete and
more detailed because they can be prepared
based on precise information from the
selected manufacturer.
– The specification can be shorter.
– They simplify the bidding by narrowing
competition and eliminating product pricing
as a major variable.
26. • Disadvantages to using proprietary
specifications:
– They reduce the competition.
– They may specify products the Contractor is
not familiar with or has had little experience
with.
– Care should be taken to assure no error is
made when specifying model numbers or
product designations.
27. Selecting a Method of
Specifying
• The following questions are helpful to
consider when deciding which method of
specifying is most appropriate.
– What does the Owner require?
– What method best describes the design
intent?
– What method is most appropriate for the
project size and complexity?
– What method will result in the best quality of
work?
– What method will result in the best price for
the work?
28. Specification Language
• Specification language should be precise.
Vague and ambiguous text can be open to
multiple interpretations.
• The following section covers how to be
precise and clear when writing specifications
and it includes a few things to avoid and
how to be concise and save space. Four
important sections for specification writing
1. Be Clear
2. Be Correct
3. Be Complete
4. Be Concise
29. 1. Be Clear:
1. Use proper grammar.
2. Chose precise words to convey the message.
2. Be Correct:
1. Present information accurately.
2. precisely using proper terminology.
3. Be Complete:
1. Do not out important or necessary information.
2. Brevity at the expense of completeness should
be avoided.
4. Be Concise:
Eliminate unnecessary words but at the expense of
clarity,correctness, completeness or grammar.
30. Sentence Structure
• Imperative Mood
Imperative mood puts the verb that defines the
action as the first word in the sentence. It is the
recommended method for specifications
covering installation of products and
equipment. It is easily understandable and
concise.
• Examples:
– Spread adhesive with notched trowel.
– Install equipment plumb and level.
– Apply two coats of paint to each exposed surface.
31. • Indicative Mood
Indicative mood uses the passive voice
with the use of the word shall in nearly
every sentence. Sometimes this can create
unnecessary wordiness and monotony.
Examples:
– Adhesive shall be spread with notched trowel.
– Equipment shall be installed plumb and level.
– Two coats of paint shall be applied to each
exposed surface.
32. Streamlined Writing
This technique uses a colon (:) to mean shall
or shall be. Streamlined specifications are
very concise and clear to read. The subject
before the colon is helpful when scanning
the specifications for keywords.
Examples:
– Adhesive: Spread with notched trowel.
– Equipment: Install plumb and level.
– Portland Cement: ASTM C 150, Type 1
33. Words to Avoid
• Typically the articles a, an and the are not
necessary and can be deleted where clarity is
not diminished. Avoid making an article or
pronoun out of the following words;
– such, said, and same.
– The use of the word all is usually unnecessary.
• Avoid: Install the equipment plumb and level.
– Such accessories shall be silver plated.
– Polish said floor with wax.
– Polish same floor with wax.
– Store all millwork under shelter.
