Solution
Major modern diseases such as
1. Ebola virus disease, 2 .Salmonellosis and 3 influenza .
1.Ebola virus disease, :
It also called Ebola hemorrhagic fever (EHF) or just Ebola, is a viral hemorrhagic fever of
people and different primates brought about by ebolaviruses.
Signs and indications ordinarily begin between two days and three weeks in the wake of getting
the infection with a fever, sore throat, solid torment, and migraines.
At that point, spewing, looseness of the bowels and rash typically take after, with diminished
capacity of the liver and kidneys.
2.salmonellosis
It is a disease caused by the Salmonella microscopic organisms.
The vast majority with salmonellosis create loose bowels, fever, heaving, and stomach issues 12
to 72 hours after disease.
Much of the time, the disease endures four to seven days, and a great many people recuperate
without treatment i
Transmission :Sullied nourishment, frequently having no bizarre look or smell
Poor kitchen cleanliness, particularly hazardous in institutional kitchens and eateries since this
can prompt to a huge flare-up .
Discharges from either wiped out or tainted yet clearly clinically sound individuals
Contaminated surface water and standing water, (for example, in shower hoses or unused water
distributors)

Describe different flow control valves with figures. Include references for the material and
figures.
Solution
DIFFERENT TYPES OF FLOW CONTROL VALVES
1. BALL VALVE
A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to
control flow through it. It is open when the ball\'s hole is in line with the flow and closed when it
is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when
open, and is perpendicular to it when closed, making for easy visual confirmation of the valve\'s
status.
Ball valves are durable, performing well after many cycles, and reliable, closing securely even
after long periods of disuse. These qualities make them an excellent choice for shutoff and
control applications, where they are often preferred to gates and globe valves, but they lack their
fine control in throttling applications.
The ball valve\'s ease of operation, repair, and versatility lend it to extensive industrial use,
supporting pressures up to 1000 bar and temperatures up to 752 °F (500 °C), depending on
design and materials used. Sizes typically range from 0.2 to 48 inches (0.5 cm to 121 cm). One
disadvantage of a ball valve is that they trap water in the center cavity while in the closed
position. In the event of a freeze, the sides can crack due to expansion of ice forming. Some
means of insulation or heat tape in this situation will usually prevent damage. Another option for
cold climates is the \"freeze tolerant ball valve\". This style of ball valve incorporates a freeze
plug in the side so in the event of a freeze up, the freeze plug ruptures, (acts as a sacrificial disk),
thus making for an easy repair. Now instead of replacing the whole valve, just screw in a new
freeze plug.
2.GATE VALVE
A gate valve, also known as a sluice valve, is a valve which opens by lifting a round or
rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the
sealing surfaces between the gate and seats are planar, so gate valves are often used when a
straight-line flow of fluid and minimum restriction is desired. The gate faces can be parallel, but
are most commonly wedge-shaped. Gate valves are primarily used to permit or prevent the flow
of liquids, but typical gate valves shouldn\'t be used for regulating flow, unless they are
specifically designed for that purpose. Because of their ability to cut through liquids, gate valves
are often used in the petroleum industry. For extremely thick fluids, a specialty valve often
known as a knife gate valve is used to cut through the liquid. On opening the gate valve, the flow
path is enlarged in a highly nonlinear manner with respect to percent of opening. This means that
flow rate does not change evenly with stem travel. Also, a partially open gate tends to vibrate
from the fluid flow. Most of the flow change occurs near shutoff with a relatively high fluid
velocity causing gate and seat wear and eventual leakage if u.

Compare and contrast transmit and receive diversity. Describe how ea.pdf
Compare and contrast transmit and receive diversity. Describe how each diversity type lead to an
improvement in system performance.
Solution
Diversity refers to a technique for improving the transmission of a signal, by receiving and
processing multiple versions of the same transmitted signal. The multiple versions can be the
result of signals following different propagation paths, being transmitted at different times or
frequencies. In Transmit diversity, Spatial diversity is introduced into the signal by transmitting
through multiple antennas. The antennas are spaced far enough so that the signals emanating
from them can be assumed to undergo independent fading. In addition to diversity gain, antenna
gain can also be incorporated through channel state feedback. TD can improve the receiver
performance in the presence of flat fading. It reduces impact of fading by offering mutliple
copies of the digitally modulated waveform at the receiver, where the chance that all copies are
simultaneously in a fade is very small. In receiver diversity, the use of diversity at receiver
needs combining the outputs of statistically independent fading channels, in accordance with a
criterion that leads to improved receiver performance. Several techniques have been studied for
diversity combining. Some of these techniques are selection combining, maximal ratio, equal
gain and square law combining. When using diversity transmission and reception, the amount of
received signal improvement depends on the independence of the fading characteristics of the
signal as well as circuit outages and failures..

C++: Doubly-Linked Lists
The goal of the exercise is to implement a class List of doubly- linked lists.
My goal is to implement the class in a file doubly-linked.cpp.
The class List implements lists using the following structures for list ele- ments:
struct Node { int val ;
Node next;
Node prev; };
Each Node contains a value (an integer) and two pointers: one meant to point to the next element
of the list and one meant to point to the previous element in the list. The class provides the
following methods that you need to implement:
• A constructor and a destructor, with no arguments;
• void insert(int n): insert an integer at the end of the list;
• void reverse(): reverse the list;
• void print(): print the list to cout in the same format as the input (i.e. integers separated by
spaces);

Assume that 96% of ticket holders show up for an airline flight. If a plane seats 200 people, how
many tickets should be sold to make the chance of an overbooked flight (more ticket holders
show up for a flight than there are seats available) is at most 10%.
Solution
Say no. of tickets booked = x
Now only 0.96x will turn up
No. of seats = 200
Now these 0.96x people should get a seat with 90% probability
200 / (0.96x) >=0.9
200/0.864 >= x
x <=231.48
x = 231

Although some male crab spiders find and mate with adult female spide.pdf
Although some male crab spiders find and mate with adult female spiders, others that find
immature females remain with them although the sub adult females are incapable of mating until

spiders and therefore all males should behave the same, either mating with adult females only or
guarding sub adult females only. c. Males that guard sub adults cannot use the time to find
receptive females. d. One would think that immature female spiders should accept and store
sperm from males in order to permit good female-finding males to have time to find many mates.

What is the \'wobble\' position? What is the consequence of its presence?
Solution
Answer : During intercation between mRNA/codons and tRNA/anticodons, The third base of the
codon and the first base of the anticodon constitutes the wobble position.
Wobble Allows Some tRNAs to Recognize More than One Codon. This is due to the fact that
strict watson and crick base pairing rules applies only to the first two bases of the codon where as
third base tRNA can recognise more than one codon..

1.) Which macronutrient do we consume in large amounts, but which we.pdf
1.) Which macronutrient do we consume in large amounts, but which we don\'t use for energy
stores?
a.) Lipid
b.) Protein
c.) Carbohydrate
d.) Minerals
2.) There are no essential _________.
a.) amino acids
b.) fatty acids
c.) carbohydrates
d.) minerals
e.) vitamins
Solution
1). b). Protein
Proteins are taken in large quantities but are not used as direct energy stores. The primary
function of proteins is not energy production, they are the structural elements of muscles and
many other cellular structures. In the absence of carbohydrates and lipids, proteins are
breakdown to derive energy.
We generally take carbohydrates in higher quantities, excess glucose is stored as glycogen. But
glycogen is not the long term energy storage because glucose is water soluble. Lipids are water-
insoluble and they serve as long-term energy stores.
2). c.) carbohydrates
Essential nutrients are those that must be taken through food to meet the body\'s metabolic
requirements. No particular carbohydrate is considered essential..

8. Which of the following sentences defines adequately horizontal gene transfer?
a) Exchange of genetic information across species
b) Movement of genetic information via binary fission
c) Exchange of genetic information via sexual reproduction
d) Transmission of genetic information from ancestors to descendants
e) Exchange of genetic information via asexual reproduction
Solution
1. The correct answer is Option A. Horizontal gene transfer is defined as the movement of
genetic material between bacteria other than by descent in which information travels through the
generations as the cell divides. The bacterial species cannot divide sexually so there are other
methods like transformation, conjugation and transduction which are employed for horizontal
gene transfer..

Salmonella is closely related to Escherichia. However, Salmonella ca.pdf
Salmonella is closely related to Escherichia. However, Salmonella can neither be infected by
lambda phage, nor can it be successfully transfected using lambda DNA. Therefore, this
organism is neither a susceptible, nor a permissive host to this virus. Explain the reason for this
failure. Please explain in detail.
Solution
It is true that Salmonella and Escherichia are the gram-negative bacteria but their genetic
architecture is different which causes distinct functional proteins for the specific functional. The
first step required to infect phage to bacteria is binding process, which comprises a precise
interaction between the host cell surface and the virus. However, the virus host interaction
critically differs amongst diverse systems. This can be mediated through various cell surface
receptors and co-receptors depends on specific virus and host. Like, j protein of lambda phage
interact with LamB surface protein of Escherichia coli. The LamB protein is an example of a
porin, also called maltoporin, due to its necessary action for growth on limited maltose. But these
receptors were absent on the surface of salmonella which restrict the lambda phage salmonella
interaction and further transfection of DNA. Few important bacteriophages are there which infect
the salmonella eg. Felix01, podophage P22 and phage epsilon15..

In gene therapy, how is the malfunctioning gene replaced No plagari.pdf
In gene therapy, how is the malfunctioning gene replaced? No plagarism!
Solution
Gene therapy is replacing defective genes with the genes having normal functionality. This
treatment can be done at different stages.Therapy done at earliest stage of life (embyonic stage)
is the most effective as it ensures gene replacement in whole lineage of cells having origin from
therapeutic cell.
Most common tool used for gene therapy are Viruses. These viruses are used as vector to carry
desirable gene. Viruses are disarmed by removal of their harmful genes .Therapeutic gene is
inserted in these viruses.
While inserting therapeutic genes it is ensured that genetic material of viruses that has coding to
control entry into host cells remains intact.
These viruses are then exposed to target cells with malfunctioned genes.These viruses then
transfer desired genes into the target cells.This step can be dne in situ or in vivo depending upon
tissue being treated.
Different types of viruses can be used for different mechanisms of DNA transfer.
Challenges in gene therapy:
1. To ensure right positioning of desirable gene into host cell.
2. Sometimes gene may be over expressed.
3. Wrong position of gene in host cell may trigger changes in expression of DNA in vicinity..
Identify one trend or force in each of the specified microenvironmen.pdf
Identify one trend or force in each of the specified microenvironments (the company, suppliers,
marketing intermediaries, competitors, publics, and customers) and describe how it would affect
\'your\' company. Example: Current CEO is retiring and the new CEO that has been selected as
the replacement has a different management style; what is the effect on the company?
Solution
The factors of microenvironment:-
1. The competitors- The competitive environment consist of certain basic things which every
firm has to take not of. No company howsoever large it may be does not enjoy monopoly. In the
original business world a company encounters various forms of competition.
For example, a Phillips TV has a competitors as LG, samsung, videocon, sony etc. And the
change in one company\'s policy affects the other in one way or the other.
2. Customers- According to Peter F. drucker, \" there is only one definition of business purpose,
that is to create customer\". The busines enterprise aims to earn profit through serving the
customer demand. It now thinks more in terms of profitable sale rather than more sales volume
for its stake. Today marketing of a fim begins and also ends with the customer.
From the company\'s ponit of view it is always better to have customer from various groups and
legions for that easily sustains demand for the company\'s product.
3. Suppliers:- Regarding the suppliers, the organisation can think of availing the required
material or labour according to its manufacturing programme. It can adopt such a purchase
policy which gives bargaining power to the organisation.
According to Michael Porter, \" the relationship between suppliers and the firms epitomises a
power equation between them. This equation is based on the industry conditions and the exent to
which each of them is dependent on the other.
Suppliers are either individuals, or business houses. They combined together, provide resources
that are needed by the company. Now the company necessarily should go for developing
specifications, searching for potential suppliers, identifying and analysing the suppliers and
thereafter choose those suppliers who offer best mix of quality, delivery, reliability, credit,
warranties and obviously low cost.
4. Public:- Literally word \' public\' refers to people in general. According to philip kotler \" A
public is any group that has an actual or potential interest in or impact on a company\'s ability to
achieve its objectives.\" The environmentalists, consumer protection groups, media persons and
local people are some of the well known examples of publics.
The company has a duty to satisfy the people at large along with competitors and the consumers.
It is an exercise which has a larger impact on the well being of the company for tomorrow\'s stay
and growth. Create goodwill among people, help to get a favourable response for a company.
5. Marketing intermediaries:- Market intermediaries are either individuals or business houses
who come to .

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

Although some male crab spiders find and mate with adult female spide.pdf
Although some male crab spiders find and mate with adult female spiders, others that find
immature females remain with them although the sub adult females are incapable of mating until
they become adults. This behavior would puzzle most evolutionary biologists because: a. The
genetic basis for this behavior would be very difficult to determine. b. Mating is instinctive in
spiders and therefore all males should behave the same, either mating with adult females only or
guarding sub adult females only. c. Males that guard sub adults cannot use the time to find
receptive females. d. One would think that immature female spiders should accept and store
sperm from males in order to permit good female-finding males to have time to find many mates.

Linked List Sorting and Reversing
Write a C++ using your own linked list class to manage a list of string elements. Besides the
basic operations expected of a linked list (add an element, remove an element, check for empty
list, report size (number) of elements in the list, and print out the content of the list), the linked
list class also needs to have a method called sort() and a method called reverse() the manipulate
the string elements. The sort method rearranges the elements in the list so they are sorted in
alphabetical order. The reverse method reverses the order of the elements of the list. Do NOT use
recursion to implement either of these operations. pls write program in c++ thanx

B). Phenotype
Biological species concept (BSC): According to the biological species concept, a biological
species is the one in which, organisms can have interbreeding and produce the viable offspring.
In contrast, the morphospecies concept relies on phenotype. The species are grouped according
to the similarities in their morphological features..
1.) Which macronutrient do we consume in large amounts, but which we.pdf
1.) Which macronutrient do we consume in large amounts, but which we don\'t use for energy
stores?
a.) Lipid
b.) Protein
c.) Carbohydrate
d.) Minerals
2.) There are no essential _________.
a.) amino acids
b.) fatty acids
c.) carbohydrates
d.) minerals
e.) vitamins
Solution
1). b). Protein
Proteins are taken in large quantities but are not used as direct energy stores. The primary
function of proteins is not energy production, they are the structural elements of muscles and
many other cellular structures. In the absence of carbohydrates and lipids, proteins are
breakdown to derive energy.
We generally take carbohydrates in higher quantities, excess glucose is stored as glycogen. But
glycogen is not the long term energy storage because glucose is water soluble. Lipids are water-
insoluble and they serve as long-term energy stores.
2). c.) carbohydrates
Essential nutrients are those that must be taken through food to meet the body\'s metabolic
requirements. No particular carbohydrate is considered essential..

8. Which of the following sentences defines adequately horizontal ge.pdf
8. Which of the following sentences defines adequately horizontal gene transfer?
a) Exchange of genetic information across species
b) Movement of genetic information via binary fission
c) Exchange of genetic information via sexual reproduction
d) Transmission of genetic information from ancestors to descendants
e) Exchange of genetic information via asexual reproduction
Solution
1. The correct answer is Option A. Horizontal gene transfer is defined as the movement of
genetic material between bacteria other than by descent in which information travels through the
generations as the cell divides. The bacterial species cannot divide sexually so there are other
methods like transformation, conjugation and transduction which are employed for horizontal
gene transfer..

Salmonella is closely related to Escherichia. However, Salmonella ca.pdf
Salmonella is closely related to Escherichia. However, Salmonella can neither be infected by
lambda phage, nor can it be successfully transfected using lambda DNA. Therefore, this
organism is neither a susceptible, nor a permissive host to this virus. Explain the reason for this
failure. Please explain in detail.
Solution
It is true that Salmonella and Escherichia are the gram-negative bacteria but their genetic
architecture is different which causes distinct functional proteins for the specific functional. The
first step required to infect phage to bacteria is binding process, which comprises a precise
interaction between the host cell surface and the virus. However, the virus host interaction
critically differs amongst diverse systems. This can be mediated through various cell surface
receptors and co-receptors depends on specific virus and host. Like, j protein of lambda phage
interact with LamB surface protein of Escherichia coli. The LamB protein is an example of a
porin, also called maltoporin, due to its necessary action for growth on limited maltose. But these
receptors were absent on the surface of salmonella which restrict the lambda phage salmonella
interaction and further transfection of DNA. Few important bacteriophages are there which infect
the salmonella eg. Felix01, podophage P22 and phage epsilon15..

In gene therapy, how is the malfunctioning gene replaced No plagari.pdf
In gene therapy, how is the malfunctioning gene replaced? No plagarism!
Solution
Gene therapy is replacing defective genes with the genes having normal functionality. This
treatment can be done at different stages.Therapy done at earliest stage of life (embyonic stage)
is the most effective as it ensures gene replacement in whole lineage of cells having origin from
therapeutic cell.
Most common tool used for gene therapy are Viruses. These viruses are used as vector to carry
desirable gene. Viruses are disarmed by removal of their harmful genes .Therapeutic gene is
inserted in these viruses.
While inserting therapeutic genes it is ensured that genetic material of viruses that has coding to
control entry into host cells remains intact.
These viruses are then exposed to target cells with malfunctioned genes.These viruses then
transfer desired genes into the target cells.This step can be dne in situ or in vivo depending upon
tissue being treated.
Different types of viruses can be used for different mechanisms of DNA transfer.
Challenges in gene therapy:
1. To ensure right positioning of desirable gene into host cell.
2. Sometimes gene may be over expressed.
3. Wrong position of gene in host cell may trigger changes in expression of DNA in vicinity..
Identify one trend or force in each of the specified microenvironmen.pdf
Identify one trend or force in each of the specified microenvironments (the company, suppliers,
marketing intermediaries, competitors, publics, and customers) and describe how it would affect
\'your\' company. Example: Current CEO is retiring and the new CEO that has been selected as
the replacement has a different management style; what is the effect on the company?
Solution
The factors of microenvironment:-
1. The competitors- The competitive environment consist of certain basic things which every
firm has to take not of. No company howsoever large it may be does not enjoy monopoly. In the
original business world a company encounters various forms of competition.
For example, a Phillips TV has a competitors as LG, samsung, videocon, sony etc. And the
change in one company\'s policy affects the other in one way or the other.
2. Customers- According to Peter F. drucker, \" there is only one definition of business purpose,
that is to create customer\". The busines enterprise aims to earn profit through serving the
customer demand. It now thinks more in terms of profitable sale rather than more sales volume
for its stake. Today marketing of a fim begins and also ends with the customer.
From the company\'s ponit of view it is always better to have customer from various groups and
legions for that easily sustains demand for the company\'s product.
3. Suppliers:- Regarding the suppliers, the organisation can think of availing the required
material or labour according to its manufacturing programme. It can adopt such a purchase
policy which gives bargaining power to the organisation.
According to Michael Porter, \" the relationship between suppliers and the firms epitomises a
power equation between them. This equation is based on the industry conditions and the exent to
which each of them is dependent on the other.
Suppliers are either individuals, or business houses. They combined together, provide resources
that are needed by the company. Now the company necessarily should go for developing
specifications, searching for potential suppliers, identifying and analysing the suppliers and
thereafter choose those suppliers who offer best mix of quality, delivery, reliability, credit,
warranties and obviously low cost.
4. Public:- Literally word \' public\' refers to people in general. According to philip kotler \" A
public is any group that has an actual or potential interest in or impact on a company\'s ability to
achieve its objectives.\" The environmentalists, consumer protection groups, media persons and
local people are some of the well known examples of publics.
The company has a duty to satisfy the people at large along with competitors and the consumers.
It is an exercise which has a larger impact on the well being of the company for tomorrow\'s stay
and growth. Create goodwill among people, help to get a favourable response for a company.
5. Marketing intermediaries:- Market intermediaries are either individuals or business houses
who come to .

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

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.
