How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
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
A Strategic Approach: GenAI in EducationPeter 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. 1a) Stimuli :-
The changes in the environment to which living
organisms respond are called stimuli.
Eg :- heat, cold, sound, smell, taste, touch, pressure,
gravity, water etc.
Living organisms respond to stimuli in the form of body
movements.
b) Coordination :-
For a proper response to a stimulus many organs in the
body should work together. The working together of
various organs in an organism to produce a proper
response to a stimulus is called coordination.
i) In animals control and co ordination is done by the
nervous system and endocrine system.
ii)In plants control and co ordination is done by chemical
substances called plant hormones or phytohormones.
3. 2) Coordination in animals :-
In animals control and co ordination is done by the nervous system
and endocrine system.
The nervous system consists of the brain, spinal cord and nerves.
a) Receptors :- are the sense organs which receive the stimuli and
pass the message to the brain or spinal cord through the sensory
nerves.
Eg :- Photoreceptors in the eyes to detect light.
Phonoreceptors in the ears to detect sound.
Olfactory receptors in the nose to detect smell.
Gustatory receptors in the tongue to detect taste.
Tangoreceptors in the skin to detect touch.
b) Effectors :- are the muscles and glands which respond to the
information from the brain and spinal cord through the motor nerves.
c) Sensory nerves :- are nerves which carry information from the
receptors (sense organs) to the brain and spinal cord.
d) Motor nerves :- are nerves which carry information from the brain
and spinal cord to the effectors (muscles and glands).
6. 3) Human nervous system :-
a) Parts of the nervous system :-
The human nervous system consists of the Central Nervous System
and Peripheral Nervous System.
i) The central nervous system :- consists of the brain, and spinal
cord.
ii) The peripheral nervous system:- consists of cranial nerves
arising from the brain and spinal nerves arising from the spinal cord.
9. b) Nerve cell (Neuron) :-
Neuron is the structural and functional unit of the nervous system. It
has a cell body called cyton containing a nucleus and cytoplasm. It has
several branched structures called dendrites. It has a long nerve fibre
called axon which is covered by a protective covering called Myelin
sheath. The junction between two neurons is called synapse.
Messages pass through the nerve cell in the form of chemical and
electrical signals called nerve impulse. The dendrites receive the
information and starts a chemical reaction which produce electrical
impulse which passes through the axon.
13. c) Brain :-
The brain is the main coordinating centre in the human body. It is
protected by the cranium. It is covered by three membranes called
meninges filled with a fluid called cerebrospinal fluid which protects
the brain from shocks.
The brain has three main parts. They are fore brain, mid brain and
hind brain.
i) Fore brain :- consists of the cerebrum and olfactory lobes. It is the
thinking part of the brain and controls voluntary actions. It controls
touch, smell, hearing, taste, sight, mental activities like thinking,
learning, memory, emotions etc.
ii) Mid brain :- controls involuntary actions and reflex movements of
head, neck, eyes etc.
iii) Hind brain :- consists of cerebellum, pons and medulla.
Cerebellum :- controls body movements, balance and posture.
Pons :- controls respiration.
Medulla :- controls heart beat, blood pressure, swallowing, coughing,
sneezing, vomitting etc.
16. d) Spinal cord :-
The spinal cord starts from the brain and extends
through the vertebral column. It has 31 pairs of spinal
nerves.
It carries messages to and from the brain. It also
controls reflex actions.
17. 4a) Reflex action :-
Reflex action is a sudden, unconcious and involuntary
response of the effectors to a stimulus.
Eg :- We suddenly withdraw our hand if we suddenly
touch a hot object.
In this reflex action, the nerves in the skin (receptor)
detects the heat and passes the message through the
sensory nerves to the spinal cord. Then the information
passes through the motor nerves to the muscles (effector)
of the hand and we withdraw our hand.
21. b) Reflex arc :-
The pathway of a reflex action is called reflex arc. In a
reflex arc the stimulus is received by the receptors (sense
organs) and it passes through the sensory nerves to the
spinal cord. From the spinal cord the information passes
through the motor nerves to the effectors (muscles/glands)
for the response.

23. 5) Coordination in plants :-
In plants control and coordination is done by chemical
substances called plant hormones or phytohormones.
There are five main types of plant hormones. They are :-
Auxins, Gibberillins, Cytokinins, Abscisic acid and
Ethylene.
i) Auxins :- help in cell division, cell elongation and
growth.
ii) Gibberillins :- help in growth of stem and branches.
iii) Cytokinins:- help in cell division, formation of fruits and
seeds.
iv) Abscisic acid :- inhibits growth and affects wilting of
leaves.
vi) Ethylene :- helps in flowering and ripening of fruits.
24. 6) Movements in plants :-
Movements in plants are of two main types. They are :-Tropic
movements and Nastic movements.
a) Tropic movements :- are directional movements towards or
away from the stimulus and it depends on growth. They are of
different types like Phototropism, Geotropism, Chemotropism,
Hydrotropism etc.
i) Phototropism :- is movement of plants in response to light. If it is
towards light, it is called positive phototropism. Eg:- Bending of
shoot towards light. If it is away from light, it is called negative
phototropism. Eg:- Bending of root away from light.
ii) Geotropism :- is the movement of plants in response to gravity. If it is
towards gravity it is called positive geotropism. Eg:- Downward
growth of roots. If it is away from gravity it is called negative
geotropism. Eg:- Upward growth of shoot.
iii) Chemotropism :- is movement of plant in response to chemical
stimuli. Eg:- Growth of pollen tube towards the ovule.
iv) Hydrotropism :- is the movement of plants in response to water.
27. b) Nastic movements :- are non directional movements which
are neither towards or away from the stimulus and it does not
depend on growth.
Eg :- If we touch the leaves of touch me not plant, its leaves fold up
and droops down immediately due to the change in the amount of
water in the leaves. Depending upon the amount of water in the
leaves, it swells or shrinks.
28. 7) Endocrine glands in human beings :-
The endocrine glands also help in control and coordination. The endocrine
glands produce chemical substances which help to control and coordinate
various activities in the body.
The endocrine glands in our body are :- pineal, hypothalamus, pituitary,
thyroid, parathyroid, thymus, adrenal, pancreas, testes and ovary.
Examples of coordination by endocrine glands :-
i)When we are frightened or angry, the adrenal glands produce more
adrenalin hormone which is sent through the blood to the heart, rib muscles
and diaphragm. This increases breathing rate to supply more oxygen to the
muscles to prepare the body to either run away or fight with the enemy.
ii)Iodine is needed by the thyroid gland to produce the hormone thyroxin.
Thyroxin controls the metabolism of carbohydrates, fats and proteins and helps
in proper growth. If the diet is deficient in iodine it causes goitre.
iii)The pituitary gland produce growth hormones. Deficiency of this hormone in
childhood causes dwarfism. Excess of this hormone causes tall growth.
iv)The pancreas produces the hormone insulin which controls the blood sugar
level. Increase in blood sugar level causes diabetes. A diabetic patient has to
take insulin injections to control his blood sugar level.
v)The testes in males produces the hormone testosterone which controls the production
of sperms and changes during puberty.
The ovary in females produces the hormone oestrogen which controls the
