A robust whistleblowing regime is now an integral part of governance.pdf
A robust whistleblowing regime is now an integral part of governance best practice for all
companies, regardless of their size or location. If you have not already done so, you should think
about introducing a whistleblowing policy or code of conduct. But simply having a
whistleblowing policy and hotline is not enough to create a culture in which employees are
genuinely encouraged to make disclosures. So what can you do to embed an open culture and
make sure your whistleblowing regime is effective?
Top-level commitment
The CEO and board should clearly support and sponsor any whistleblowing regime. Board
members or other senior managers must be seen to respect the policy. If anyone discourages
whistleblowing this will significantly undermine other efforts. Senior accountability A senior
member of management must have overall responsibility for embedding the culture of internal
disclosure throughout the company – particularly within management.This person should also
announce the policy to all employees, manage and review it, and feedback on it to the board.
What’s more, he or she must have enough resources to be able to do this well.
Communication and training
Employees must know the regime is in place and understand when and how to use it. Some
businesses ensure this with regular emails, videos and presentations from the CEO, responsible
manager or general counsel. Comprehensive training must be compulsory for all, run regularly
and records of employee attendance should be kept. It may be sensible to require employees to
sign an annual declaration that they have read and understood the policy and received training. If
there is a danger of training fatigue, make whistleblowing training part of the company’s general
compliance training and reserve more intensive training for employees with managerial
responsibilities.
Regular review and audit
Regularly review any whistleblowing policies and prepare reports on the number and types of
disclosures received in any given year. Asking the questions below will help your board to assess
how the policy can be applied most effectively.
• Are disclosures widespread across the company or very limited?
• Are they concentrated in a particular business area or scattered across all areas?
• Are the numbers of disclosures going up or down?
• Do employees feel able to make disclosures?
• Are the types of issues being disclosed through the policy appropriate and sensible?
• How have disclosures been investigated and followed up?
You could also give employees updates on a more general level. This lets them see that people
are making disclosures and that those disclosures are being encouraged and dealt with
appropriately. Bring the information to life with anonymised examples of disclosures and how
they were handled
Proper investigation and action
It is essential that the whistleblowing policy is enforced. Any disclosure must be investigated
promptly and properly. Take appropriate action at the right level. The pol.
1. In higher parts of the reef, where the wave energy is high, the c.pdf
1. In higher parts of the reef, where the wave energy is high, the coral forms tend to assume
either encrusting or massive, ex:brain corals. Going further deep down, massive corals dominate
and eventually give way to branching coral forms (because as depth increases, wave energy
decerases). At the base of the reef front, there are plate-like coral forms. They are deep down
(diminished light) and hence orient their flat surface to gain maximum amount of sunlight.
Further deep, limestone boulders, coral branches, soft corals sponges and algae are found.
Thus, the answer for this question is, brain coral forms dominate where there is shallow water
and high wave energy.
2. Menhadens spawn in the inshores water of the Atlantic coast. The eggs hatch in the ocean and
drift to estuaries along with ocean currents. These young ones stay around for certain period of
time before, they return to the ocean. their early stage is known as \"peanut bunker\". The larval
fish moves into low salinity waters in estuaries and the juveniles fish remain the bay untill the
fall.
Thus, the answer for this question is menhaden fish spend their larval and juvenile (option d)
ontogenic stage at the Chesapeake Bay .
3. Sea urchins are the biggest kelp grazers. A massive density of sea urchins is suffiecient
enough to eliminate kelp forest. But at times, when densities of kelps dominate, they secrete
secondary compounds to defend themselves from the sea urchin. Thus it basically depends upon
the densities of each species and their dominance over an are. However, sea urchins are the
greatest grazers of kelps that play a role in their abundance.
4. Recruitment in marine biology means, surving of new young one. Recruitment limitation is
the limit to ho much recruitment is possible. In this case, greater the recruitment of species, the
greater the diversity of niche and hence greater is the diversity of high reef fish.The recruitment
limitation model suggest that high reef fish diversity is due to niche diversity.
5. Reef building corals are temperature sensitive and that is why confined to tropical and semi
tropical waters. Their optimal temperature range is 23o- 29o celsius. They cannot tolerate
temperature below 18o celsius, and very few can tolerate temperatures as high as 40o celsius.
Thus, coral reefs forms in areas where seawater temperatures averages no less than 18o celsius.

NaCl Its the coulombic interaction between Na.pdf
NaCl : It\'s the coulombic interaction between Na+ and Cl- due to which crystal
exists. It\'s not ionic intereaction. It\'s ionic interaction. (very strong). NaCl dissolves in water.
It\'s not due to hydrogen bonding. It\'s due to strong ion-dipole interactions. Initially, the
positive and negative ion are only attracted to each other. The water molecules are hydrogen
bonded to each other. If the crystal is to dissolve, these bonds must be broken. Negative chloride
ions on the surface are attracted by neighboring positive sodium ions and by the partially positive
hydrogen atom in the polar water molecule (See the graphic on the left). Similarly, the positive
sodium ions are attracted by both chloride ions and the partially negative oxygen atom in the
polar water molecule. A \"tug-of-war\" occurs for the positive and negative ions between the
other ions in the crystal and the water molecules. Several water molecules are attracted to each of
the ions. Whether the crystal dissolves is determined by which attractive force is stronger. If the
internal ionic forces in the crystal are the strongest, the crystal does not dissolve. This is the
situation in reactions where precipitates form. If the attractions for the ions by the polar water
molecules are the strongest, the crystal will dissolve. This is the situation in sodium chloride.
Once the ions are released from the crystals, the ions are completely surrounded by water
molecules. Note that the proper atom in the water molecule must \"point\" toward the correct ion.
The charge principle and the partial charges in the polar molecule determine the correct
orientation. Partially negative oxygen atoms in the water molecule interact with the positive
sodium ion. Partially positive hydrogen atoms in the water molecule interact with the negative
chloride ion. Sugar : The interaction between sugar molecule and water is greater than between
sugar molecules. So When sugar is put into water, it likes to form hydrogen bonds with water. So
it breaks glycosidic linkages and forms hydrogen bonds with water. Initially it separates into
polymer sugar chains, but later it dissociates into individual molecules.
Solution
NaCl : It\'s the coulombic interaction between Na+ and Cl- due to which crystal
exists. It\'s not ionic intereaction. It\'s ionic interaction. (very strong). NaCl dissolves in water.
It\'s not due to hydrogen bonding. It\'s due to strong ion-dipole interactions. Initially, the
positive and negative ion are only attracted to each other. The water molecules are hydrogen
bonded to each other. If the crystal is to dissolve, these bonds must be broken. Negative chloride
ions on the surface are attracted by neighboring positive sodium ions and by the partially positive
hydrogen atom in the polar water molecule (See the graphic on the left). Similarly, the positive
sodium ions are attracted by both chloride ions and the partially negative oxygen atom in the
polar water molecule. A \"tug-of-war\" occurs for.
Here Jupiter is the fifth planet from the Sun a.pdf
Here: Jupiter is the fifth planet from the Sun and the largest planet within the Solar
System.It is a gas giant with a mass slightly less than one-thousandth of the Sun but is two and a
half times the mass of all the other planets in our Solar System combined. Jupiter is classified as
a gas giant along with Saturn, Uranus and Neptune. Together, these four planets are sometimes
referred to as the Jovian or outer planets. The planet was known by astronomers of ancient times
and was associated with the mythology and religious beliefs of many cultures. The Romans
named the planet after the Roman god Jupiter.[14] When viewed from Earth, Jupiter can reach
an apparent magnitude of -2.94, making it on average the third-brightest object in the night sky
after the Moon and Venus. (Mars can briefly match Jupiter\'s brightness at certain points in its
orbit.) Jupiter is primarily composed of hydrogen with a quarter of its mass being helium; it may
also have a rocky core of heavier elements. Because of its rapid rotation, Jupiter\'s shape is that
of an oblate spheroid (it possesses a slight but noticeable bulge around the equator). The outer
atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence
and storms along their interacting boundaries. A prominent result is the Great Red Spot, a giant
storm that is known to have existed since at least the 17th century when it was first seen by
telescope. Surrounding the planet is a faint planetary ring system and a powerful magnetosphere.
There are also at least 63 moons, including the four large moons called the Galilean moons that
were first discovered by Galileo Galilei in 1610. Ganymede, the largest of these moons, has a
diameter greater than that of the planet Mercury. Jupiter has been explored on several occasions
by robotic spacecraft, most notably during the early Pioneer and Voyager flyby missions and
later by the Galileo orbiter. The most recent probe to visit Jupiter was the Pluto-bound New
Horizons spacecraft in late February 2007. The probe used the gravity from Jupiter to increase its
speed. Future targets for exploration in the Jovian system include the possible ice-covered liquid
ocean on the moon Europa. Jupiter\'s structure: Jupiter is composed primarily of gaseous and
liquid matter. It is the largest of four gas giants as well as the largest planet in the solar system
with a diameter of 142,984 km at its equator. The density of Jupiter, 1.326 g/cm³, is the second
highest of the gas giant planets. However, the density is lower than any of the four terrestrial
planets.

a.Times Interest Earned Ratio = EBIT interest ExpenseFor 2014.pdf
a.
Times Interest Earned Ratio = EBIT / interest Expense
For 2014: $8,799 / $600 = 14.7 times
For 2015: $9,454 / $838 = 11.3 times
For 2016: $10,338 / $1,058 = 9.8 times
The TImes Interest Earned (TIE) Ratio measures the operating income level that can be used for
interest payments in the future, i.e. how many times the Company can make the interest
payments. It is a solvency ratio since it measures the Company\'s ability to service it\'s debt
interest obligations. Hence, the higher the ratio, the more favorable is the company\'s liquidity
position.
In the given question, we can observe that the ratio has consistently decreased year on year. This
implies that the Company\'s debt has increased while the increase in operating income has not
been at the same pace. The Company can afford to service interest fewer times each year from
2014 to 2016. This implies that the Company has become comparatively more risky than before
from the Creditor\'s standpoint.
b. Current Ratio = Current Assets / Current Liabilities
For 2014: $25,983 / $19,027 = 1.4
For 2015: $29,158 / $23,169 = 1.3
For 2016: $31,042 / $26,250 = 1.2
The Current Ratio is an indicator of how efficiently the Company manages it\'s operating cycle.
A higher Current Ratio implies that the COmpany is in a better position to discharge all it\'s short
term obligations without affecting or jeopardising it\'s working capital requirements. On the
flipside, a ratio that is too high indicates that the Company\'s current assets are lying idle or that
it is not efficiently using short term funds.
In the Given case, the Company\'s current ratio shows a steady decline. However, the lowest is
1.2 times, which implies that the Company is still sufficiently liquid. This is becase even at the
lowest, the Company\'s Current Assets can pay off the Current Liabilities 1.2 times without
affecting working capital cycle for regular business needs.
Hence, as per the options given, we can say that CVS’s current ratio has decreased over the past
three years, however, it is greater than 1 indicating CVS is liquid.
c. Total Liabilities to Equity Ratio = Total Liabilities / Total Equity
For 2014: $36,224 / $37,963 = 0.95
For 2015: $55,234 / $37,203 = 1.5
For 2016: $57,628 / $36,834 = 1.6
Total Liabilities include all the claims, long term and short term, against the Company\'s
Assets. Total Liabilities to Equity Ratio indicates how much of the Company\'s Assets are
funded by creditors versus how much is funded by the equity holders. Broadly, a 1:1 ratio is
considered acceptable for most industries. Creditors would prefer a lower ratio as this implies
their money is at less risk. However, equity holders would like to benefit from the risk taken by
them due to the Company using debt, and would prefer a higher ratio.
In the given case, this ratio is increasing year on year. This implies that the COmpany is taking
on more debt financing. This implies that the Company has more risk overall, although it
benefits the equity .

An undirected graph is acyclic (i.e., a forest) iff a DFS yields no .pdf
An undirected graph is acyclic (i.e., a forest) iff a DFS yields no back edges. Since back edges
are those edges (u, v) connecting a vertex u to an ancestor v in a depth-first tree, so no back
edges means there are only tree edges, so there is no cycle. So we can simply fun DFS. If find a
back edge, there is a cycle. The complexity is O(V ) instead of O(E + V ). Since if there is a back
edge, it must be found before seeing |V | distinct edges. This is because in a acyclic (undirected )
forest, |E| |V | + 1

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
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

NaCl Its the coulombic interaction between Na.pdf
NaCl : It\'s the coulombic interaction between Na+ and Cl- due to which crystal
exists. It\'s not ionic intereaction. It\'s ionic interaction. (very strong). NaCl dissolves in water.
It\'s not due to hydrogen bonding. It\'s due to strong ion-dipole interactions. Initially, the
positive and negative ion are only attracted to each other. The water molecules are hydrogen
bonded to each other. If the crystal is to dissolve, these bonds must be broken. Negative chloride
ions on the surface are attracted by neighboring positive sodium ions and by the partially positive
hydrogen atom in the polar water molecule (See the graphic on the left). Similarly, the positive
sodium ions are attracted by both chloride ions and the partially negative oxygen atom in the
polar water molecule. A \"tug-of-war\" occurs for the positive and negative ions between the
other ions in the crystal and the water molecules. Several water molecules are attracted to each of
the ions. Whether the crystal dissolves is determined by which attractive force is stronger. If the
internal ionic forces in the crystal are the strongest, the crystal does not dissolve. This is the
situation in reactions where precipitates form. If the attractions for the ions by the polar water
molecules are the strongest, the crystal will dissolve. This is the situation in sodium chloride.
Once the ions are released from the crystals, the ions are completely surrounded by water
molecules. Note that the proper atom in the water molecule must \"point\" toward the correct ion.
The charge principle and the partial charges in the polar molecule determine the correct
orientation. Partially negative oxygen atoms in the water molecule interact with the positive
sodium ion. Partially positive hydrogen atoms in the water molecule interact with the negative
chloride ion. Sugar : The interaction between sugar molecule and water is greater than between
sugar molecules. So When sugar is put into water, it likes to form hydrogen bonds with water. So
it breaks glycosidic linkages and forms hydrogen bonds with water. Initially it separates into
polymer sugar chains, but later it dissociates into individual molecules.

Here Jupiter is the fifth planet from the Sun a.pdf
Here: Jupiter is the fifth planet from the Sun and the largest planet within the Solar
System.It is a gas giant with a mass slightly less than one-thousandth of the Sun but is two and a
half times the mass of all the other planets in our Solar System combined. Jupiter is classified as
a gas giant along with Saturn, Uranus and Neptune. Together, these four planets are sometimes
referred to as the Jovian or outer planets. The planet was known by astronomers of ancient times
and was associated with the mythology and religious beliefs of many cultures. The Romans
named the planet after the Roman god Jupiter.[14] When viewed from Earth, Jupiter can reach
an apparent magnitude of -2.94, making it on average the third-brightest object in the night sky
after the Moon and Venus. (Mars can briefly match Jupiter\'s brightness at certain points in its
orbit.) Jupiter is primarily composed of hydrogen with a quarter of its mass being helium; it may
also have a rocky core of heavier elements. Because of its rapid rotation, Jupiter\'s shape is that
of an oblate spheroid (it possesses a slight but noticeable bulge around the equator). The outer
atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence
and storms along their interacting boundaries. A prominent result is the Great Red Spot, a giant
storm that is known to have existed since at least the 17th century when it was first seen by
telescope. Surrounding the planet is a faint planetary ring system and a powerful magnetosphere.
There are also at least 63 moons, including the four large moons called the Galilean moons that
were first discovered by Galileo Galilei in 1610. Ganymede, the largest of these moons, has a
diameter greater than that of the planet Mercury. Jupiter has been explored on several occasions
by robotic spacecraft, most notably during the early Pioneer and Voyager flyby missions and
later by the Galileo orbiter. The most recent probe to visit Jupiter was the Pluto-bound New
Horizons spacecraft in late February 2007. The probe used the gravity from Jupiter to increase its
speed. Future targets for exploration in the Jovian system include the possible ice-covered liquid
ocean on the moon Europa. Jupiter\'s structure: Jupiter is composed primarily of gaseous and
liquid matter. It is the largest of four gas giants as well as the largest planet in the solar system
with a diameter of 142,984 km at its equator. The density of Jupiter, 1.326 g/cm³, is the second
highest of the gas giant planets. However, the density is lower than any of the four terrestrial
planets.

a.Times Interest Earned Ratio = EBIT interest ExpenseFor 2014.pdf
a.
Times Interest Earned Ratio = EBIT / interest Expense
For 2014: $8,799 / $600 = 14.7 times
For 2015: $9,454 / $838 = 11.3 times
For 2016: $10,338 / $1,058 = 9.8 times
The TImes Interest Earned (TIE) Ratio measures the operating income level that can be used for
interest payments in the future, i.e. how many times the Company can make the interest
payments. It is a solvency ratio since it measures the Company\'s ability to service it\'s debt
interest obligations. Hence, the higher the ratio, the more favorable is the company\'s liquidity
position.
In the given question, we can observe that the ratio has consistently decreased year on year. This
implies that the Company\'s debt has increased while the increase in operating income has not
been at the same pace. The Company can afford to service interest fewer times each year from
2014 to 2016. This implies that the Company has become comparatively more risky than before
from the Creditor\'s standpoint.
b. Current Ratio = Current Assets / Current Liabilities
For 2014: $25,983 / $19,027 = 1.4
For 2015: $29,158 / $23,169 = 1.3
For 2016: $31,042 / $26,250 = 1.2
The Current Ratio is an indicator of how efficiently the Company manages it\'s operating cycle.
A higher Current Ratio implies that the COmpany is in a better position to discharge all it\'s short
term obligations without affecting or jeopardising it\'s working capital requirements. On the
flipside, a ratio that is too high indicates that the Company\'s current assets are lying idle or that
it is not efficiently using short term funds.
In the Given case, the Company\'s current ratio shows a steady decline. However, the lowest is
1.2 times, which implies that the Company is still sufficiently liquid. This is becase even at the
lowest, the Company\'s Current Assets can pay off the Current Liabilities 1.2 times without
affecting working capital cycle for regular business needs.
Hence, as per the options given, we can say that CVS’s current ratio has decreased over the past
three years, however, it is greater than 1 indicating CVS is liquid.
c. Total Liabilities to Equity Ratio = Total Liabilities / Total Equity
For 2014: $36,224 / $37,963 = 0.95
For 2015: $55,234 / $37,203 = 1.5
For 2016: $57,628 / $36,834 = 1.6
Total Liabilities include all the claims, long term and short term, against the Company\'s
Assets. Total Liabilities to Equity Ratio indicates how much of the Company\'s Assets are
funded by creditors versus how much is funded by the equity holders. Broadly, a 1:1 ratio is
considered acceptable for most industries. Creditors would prefer a lower ratio as this implies
their money is at less risk. However, equity holders would like to benefit from the risk taken by
them due to the Company using debt, and would prefer a higher ratio.
In the given case, this ratio is increasing year on year. This implies that the COmpany is taking
on more debt financing. This implies that the Company has more risk overall, although it
benefits the equity .

An undirected graph is acyclic (i.e., a forest) iff a DFS yields no back edges. Since back edges
are those edges (u, v) connecting a vertex u to an ancestor v in a depth-first tree, so no back
edges means there are only tree edges, so there is no cycle. So we can simply fun DFS. If find a
back edge, there is a cycle. The complexity is O(V ) instead of O(E + V ). Since if there is a back
edge, it must be found before seeing |V | distinct edges. This is because in a acyclic (undirected )
forest, |E| |V | + 1

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
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.

Operation Blue Star - Saka Neela Tara
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.

A Strategic Approach: GenAI in Education
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 ...
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.
