I have two statistics questions, I was wondering if you could answer and explain them to me:
Q1: The F distribution is a family of two-sided distributions characterized by the following
notation:
N(0,1)
N(1,1)
N(1,0)
None of the above.
Q2: The z distribution is a family of two-sided distributions characterized by the following
notation:
N(0,1)
N(1,1)
N(1,0)
None of the above.
Solution
Q1) none. F is represented by F and 2 degrees of freedom
Q2) N(0,1) is correct for Z distribution.
How does increased transcription (mutation in the G1-S- checkpoint p.pdf
How does increased transcription (mutation in the G1-S- checkpoint phase) help a virus?
Solution
Some the viruses have RNA as genetic material. So the translation is the main process for the
sythesis of protein molecules. Hence the increased transcription due to the muatation in the G1-S
checkpoint phase helps the virus to produce proetins that can infect the host. For RNA viruses
dierctly the m-RNA is translated and for DNA based Viruses first the transcription and
translation.Thus the m-RNA helps in constructiing the cell components of viruses using host cell..

Early in my auditing career, I always wondered how do I know when .pdf
Early in my auditing career, I always wondered \'how do I know when I\'ve got enough evidence
to render an opinion?\' How might you answer this?
Solution
Objective:
The objective of the auditor is to plan and perform the audit to obtain appropriate audit evidence
that is sufficient to support the opinion expressed in the auditor\'s report.
Sufficient Appropriate Audit Evidence:
The auditor must plan and perform audit procedures to obtain sufficient appropriate audit
evidence to provide a reasonable basis for his or her opinion.
Sufficiency is the measure of the quantity of audit evidence. The quantity of audit evidence
needed is affected by the following:
Appropriateness is the measure of the quality of audit evidence, i.e., its relevance and reliability.
To be appropriate, audit evidence must be both relevant and reliable in providing support for the
conclusions on which the auditor\'s opinion is based..
Discus the development of the fraud examinerforensic accounting pro.pdf
Discus the development of the fraud examiner/forensic accounting profession since the 2001
Enron fraud. Discuss applicable standards and the core foundation of the profession.
Solution
Forensic accounting has been pivotal in the corporate agenda after the financial reporting
problems which took place in some companies around the world like Enron. These scandals
resulted in the loss of public trust and huge amounts of money. In order to avoid fraud and theft,
and to restore the badly needed public confidence, several companies took the step to improve
the infrastructure of their internal control and accounting systems drastically. It was this
development which increased the importance of accountants who have chosen to specialize in
forensic accounting and who are consequently referred as “forensic accountants.”
Forensic accounting relies on the fraud triangle to identify weak points in the business systems
and find possible suspects in cases of fraud. It consists of three core concepts which together
create a situation ripe for fraud: incentive, opportunity, and rationalization. People must have the
incentive and opportunity to commit financial fraud, as well as the ability to justify it. Recent
analysis has suggested adding a fourth concept to make a diamond—capability. Just because
someone has the opportunity or incentive to steal does not necessarily mean that they have the
capability to do so. For example, if someone does not understand how to make journal or ledger
entries in the books of accounts, they would not know how to manipulate numbers no matter
what the incentive or opportunity is.
The accounting scandals involving Enron, WorldCom, Global Crossing, and other companies
have put accountants in the public spotlight as never before in their history. After these
accounting scandals, public confidence in the accounting profession has been seriously
undermined. However, the scandals have created business for forensic accountants and
developed opportunities for forensic and investigative accounting. Forensic accountants have
been conducting these activities for quite some time in a quiet professional manner. New laws
and regulations resulting from these scandals will make the role of forensic accountants more
important than ever before in the business world.
Forensic accountants, also referred to as forensic auditors or investigative auditors, often have to
give expert evidence at the eventual trial. All of the larger accounting firms as well as many
medium-sized and boutique firms have specialist forensic accounting departments. Forensic
accountants utilize an understanding of business information and financial reporting systems,
accounting and auditing standards and procedures, evidence gathering and investigative
techniques, and litigation processes and procedures to perform their work. Forensic accountants
are also increasingly playing more proactive risk reduction roles by designing and performing
extended procedures as part of stat.
Could a cell survive by having just peripheral proteins on it’s memb.pdf
Could a cell survive by having just peripheral proteins on it’s membrane? Why?
Solution
Principal component of plasmamembrane are lipids , phospholipid and carbohydrate .
Phospholipid make good barrier between interior and exterior of cell . Phospholipid , cholestrol
expand range of temperature for normal functioning of membrane. So without Phospholipid it is
not possible that membrane survive .Peripheral protein only help in signal transduction and allow
only certain molecules in and out of cell. They also function as receptor for hormone etc..

C++ Sorting The parameter to the following two recursive routines is.pdf
C++ Sorting The parameter to the following two recursive routines is a pointer to a singly linked
list of numbers, whose elements are unique (no duplicates) and unsorted. Each node in the list
contains two members, info (a number) and next (a pointer to the next node). Write a recursive
value-returning function, MinLoc, that receives a pointer to a list of unsorted numbers and
returns a pointer to the node that contains the minimum value in the list. Write a recursive void
function, Sort, that receives a pointer to an unsorted list of numbers and reorders the values in the
list from smallest to largest. This function may call the recursive MinLoc function that you wrote
in part
Solution
Here is the solution for part(a):
int linked_list::MinLoc(node *head)
{
if(head == NULL)
return -1;
else if(head->next == NULL)
return head->info;
else
return (head->info < MinLoc(head->next) ? head->info : MinLoc(head->next));

Briefly discuss five criteria used to classify an organism as a multi.pdf
Briefly discuss five criteria used to classify an organism as a multicelled animal?
Solution
Organisms that consist of more than one cell are known as multicellular organisms. Multicelluar
organisms are made up of more than one cell. These cells identify and attach to each other to
form a multicellular organism. Most of the multicellular organisms are visible to the naked eye.
Organisms like plants, animals, and some algae from a single cell and they grow up into a
multicelled organism. Both prokaryotes and eukaryotes show multicellularity. True multicellular
organisms regenerate a whole organism from germ cells.
There are there theories to discuss the mechanisms by which multicellularity could have evolved.
Symbiotic Theory- Symbiotic theory states that the first multicellular organism arose from
symbiosis behaviour of different species of a single-celled organism, each performing different
functions. Such symbiotic relation ship is seen between clown fish and Riterri sea anemones.
The Cellularization Theory or The Syncytial Theory- The cellularization theory states a
unicellular organismwould have developed from membrane boundaries/partitions around each
nuclei from a single celled organisms with multiple nuclei. Protists like cliates and slime molds
have multiple nuclei supporting this theory.
The Colonial Theory- The colonial theory that the symbiosis of many organisms of the same
species led to the evolution of multicellular organisms. This theory was proposed by Haecked in
1874.Majority of multicellularity occurs as a consequence of the cells falling to separate
following the process of division. Example of this theory can be seen in multicellular protists like
Volvox, Eudorina.
Advantages of Multicellularity in organism are that multicellularity allows the organism to
exceed the size limits. Multicelluarity also permits in increasing the complexity of the organism
by allowing differentiation of numerous cellular lineages in an organism.
Animals are multicellular and move with the aid of cilia, flagella, or muscular organs based on
contractile proteins. They have organelles including a nucleus, but no chliorplasts or cell walls.
Animals acquire nutrients by ingestion.
They have multiple cell with mitochondria and they depend on other organisms for food
Biologists recognize 36 phyla in the animals kingdom.
Size-The size of animals ranges from a few celled organosm like the mesozoans to animals
weighing many tones like the blue whale.
Animals bodies- Bodies of animals are made of cells organized into tissues which perform
specific functions in most animals tissue are organized into complex organs, which form organ
systems.
Cell structure_ The animal cell contains organelles like the nucleus, mitochondria, Golgi
complex, ribosomes, endoplasmic reticulum, lysosomes, vacuoles, centrioles, cytoskeieton.
Animals are made up of many organs systems, that aids in performing specific functions that are
necessary for the survival of the organism.

Which of the following statements about detritivores is true they a.pdf
Which of the following statements about detritivores is true? they are an energy component,
they eat dead organic material, and they occupy a trophic level they store energy at a higher
intensity that carnivores, they are scavengers, and they are a trophic pest they are an energy
flow, they undergo chemosynthesis, and they are not a part of the food web they generate their
own energy sugar molecules, they are carnivores, and they can cause eutrophication of aquatic
ecosystems
Solution
Detrivores are the special type of organism that is feed on the dead and decaying organic matters,
breaks the complex molecules of the decaying organism and makes the broken organic material
useful for the plant as nutrients.
Therefore, detrivores are the energy compartment, they eat dead organic material and they
occupy a trophic level..
What is the role of anaerobic cellular respiration in the nitrogen c.pdf
What is the role of anaerobic cellular respiration in the nitrogen cycle, and how does anaerobic
respiration differ from aerobic respiration?
Solution
Organisms that perform anaerobic respiration like Pseudomonas denitrificans take oxidized form
of nitrogen like nitrous oxide as terminal electron acceptor and convert it to nitrogen which is
released in air. This is an important step of nitrogen cycle known as denitrification.

The following figure shows two possible groups of species on which to.pdf
The following figure shows two possible groups of species on which to focus conservation
efforts. Why might you choose a conservation strategy that would save the two species in blue
rather than the three species in red? Saving two closely related species preserves more
phylogenetic history than saving three more distantly related species. Saving the blue species
preserves more phylogenetic diversity. The blue species are easier to preserve because they have
not evolved as much as the red species. The red species are not important to the ecology of their
habitat.
Solution
Saving the blue species preserves more phylogenetic diversity.
Long brances mean very long evolution. Those species evilved in such a way that they have their
iwn niche and can be easily conserved. Short branches means closely related species and less
genetic diversity..

Ted Hollis is famous for making the case that all intelligence of humans resides in their cellular
membranes.
Explain in detail what different parts of the fluid mosaic model do and how it relates to function
and the intelligence of the cell.
Solution
Fluid Mosaic Model represent the nature of the cell membrane. It describes the cell membrane as
a dynamic structure made up of a double layer of phospholipids embedded with protein and
carbohydrates.
Parts of cell membrane contributing to function and intelligence of the cell -
The plasma membrane consists of Lipid Rafts, which are a combinaton of phospholipids and
protein. These ipid rafts play a role in the signalling mechanism of the cell, allowing cell to
maintain various processes of Inter and intra cellular transfer and transfer of signals meant for
cells.
Membrane Assymetry refers to the difference in the composition of the inner and outer layer of
the plasme membrane bilayer. This assymetry contribute in making the inner and outer layer
differentiable to cell signalling mechanism and serve as differential receptor for performing
different functions meant either for the inner or the outer layer. Enzymes like Flippase and
Scrambalase maintain this assymetry.
The Assymetry serves in function like apoptosis where reversal of the positions of the membrane
serve as a signal for the the cell to be recognized for apoptosis to take place.

Q. How do steroid hormones enter a cell and bring about change in ex.pdf
Q. How do steroid hormones enter a cell and bring about change in expression of genes in the
nucleus?
Solution
Steroid hormones are non-water soluble hormones. They are present in the blood bound to
specific protein carriers.
When they have to enter a cell they dissociate from the protein carriers and enters the cell
through simple diffusion.
Once entering the cell these hormones bind to hormone receptor proteins present in the
cytoplasm and move as a hormone receptor complex into the nucleus where it encounters the
DNA. Binding of hormone to receptor protein changes its conformational structure making it
competent to bind DNA.
DNA inside the nucleus contains specific hormone response elements which recognises and
binds to DNA binding regions of intracellular receptor protein.
The receptor protein also contains region which interacts with transcription factors thus initiating
transcription at hormone response elements of DNA.
After transcription the mRNA moves to cytoplasm where specific proteins are synthesized
through translation..
Provide an in depth description of biological information transfer (.pdf
Provide an in depth description of biological information transfer (what is the chemistry
underlying each information transfer event, which nucleotide sequences are involved etc.)
Solution
The genetic information is stored in Deoxyribonucleic acid,DNA. DNA contains the information
needed to build an individual. Genetic information is transferred from DNA and converted to
protein.RNA molecules work as messengers.Proteins are the biological workers.Information of
the DNA is copied to a RNA molecule in transcription.RNA directs the protein synthesis in a
translation.Protein’s 3D structure determines it’s function.Information transfer only in one
direction.
The biological information flows from DNA to RNA,and from there to proteins.It is ultimately
the DNA that controls every function of the cell through protein synthesis.As a carrier of genetic
information,DNA in a cell must be duplicated (replicated),maintained and passed dawn
accurately to the daughter cells.
DNA is deoxyribonucleic acid,which is found in chromosomes, contains inherited
information,they are made up of nucleotides,and are what make up genes. A nucleotide is
composed of a sugar (deoxyribose),a phosphate group,and a base.There are 4 bases found in
DNA, Adenine (A),Thymine (T),Guanine (G),and Cytosine (C).Adenine and guanine are double
ring bases while thymine and cytosine are single ring bases.Nucleotides are joined to each other
by covalent bonds between the phosphate group of one nucleotide and the 3\' carbon atom of the
deoxyribose (sugar) of the next nucleotide.Each DNA molecule is unique because the order of
nucleotides is unique. The order of nucleotides determines the order of amino acids in a
protein.RNA is a nucleic acid composed of nucleotides and consists of one strand of
nucleotides.There are three different types of RNA- Ribosomal,Messenger,and
Transfer.Ribosomal RNA is the RNA molecules found in ribosomes. The large subunit RNA
contains the enzymatic activity that makes the peptide bonds between amino acids. Messenger
RNA is what controls the order of amino acids in a protein and determines which gene it codes
for.Transfer RNA brings amino acids to ribosomes.The transfer RNA has two recognition sites-
one recognizes an amino acid and the other recognizes one codon.The transfer RNA brings the
the correct amino acid to the ribosome.
Transcription is the process by which the information contained in a section of DNA is replicated
in the form of a newly assembled piece of messenger RNA (mRNA).Enzymes facilitating the
process include RNA polymerase and transcription factors.In eukaryotic cells the primary
transcript is pre-mRNA. Pre-mRNA must be processed for translation to proceed.Processing
includes the addition of a 5\' cap and a poly-A tail to the pre-mRNA chain,followed by
splicing.Alternative splicing occurs when appropriate, increasing the diversity of the proteins
that any single mRNA can produce.The product of the entire transcription process is a mature
mRNA ch.

Francesca Gottschalk - How can education support child empowerment.pptx
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
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.

Solution
Objective:
The objective of the auditor is to plan and perform the audit to obtain appropriate audit evidence
that is sufficient to support the opinion expressed in the auditor\'s report.
Sufficient Appropriate Audit Evidence:
The auditor must plan and perform audit procedures to obtain sufficient appropriate audit
evidence to provide a reasonable basis for his or her opinion.
Sufficiency is the measure of the quantity of audit evidence. The quantity of audit evidence
needed is affected by the following:
Appropriateness is the measure of the quality of audit evidence, i.e., its relevance and reliability.

Discus the development of the fraud examinerforensic accounting pro.pdf
Discus the development of the fraud examiner/forensic accounting profession since the 2001
Enron fraud. Discuss applicable standards and the core foundation of the profession.
Solution
Forensic accounting has been pivotal in the corporate agenda after the financial reporting
problems which took place in some companies around the world like Enron. These scandals
resulted in the loss of public trust and huge amounts of money. In order to avoid fraud and theft,
and to restore the badly needed public confidence, several companies took the step to improve
the infrastructure of their internal control and accounting systems drastically. It was this
development which increased the importance of accountants who have chosen to specialize in
forensic accounting and who are consequently referred as “forensic accountants.”
Forensic accounting relies on the fraud triangle to identify weak points in the business systems
and find possible suspects in cases of fraud. It consists of three core concepts which together
create a situation ripe for fraud: incentive, opportunity, and rationalization. People must have the
incentive and opportunity to commit financial fraud, as well as the ability to justify it. Recent
analysis has suggested adding a fourth concept to make a diamond—capability. Just because
someone has the opportunity or incentive to steal does not necessarily mean that they have the
capability to do so. For example, if someone does not understand how to make journal or ledger
entries in the books of accounts, they would not know how to manipulate numbers no matter
what the incentive or opportunity is.
The accounting scandals involving Enron, WorldCom, Global Crossing, and other companies
have put accountants in the public spotlight as never before in their history. After these
accounting scandals, public confidence in the accounting profession has been seriously
undermined. However, the scandals have created business for forensic accountants and
developed opportunities for forensic and investigative accounting. Forensic accountants have
been conducting these activities for quite some time in a quiet professional manner. New laws
and regulations resulting from these scandals will make the role of forensic accountants more
important than ever before in the business world.
Forensic accountants, also referred to as forensic auditors or investigative auditors, often have to
give expert evidence at the eventual trial. All of the larger accounting firms as well as many
medium-sized and boutique firms have specialist forensic accounting departments. Forensic
accountants utilize an understanding of business information and financial reporting systems,
accounting and auditing standards and procedures, evidence gathering and investigative
techniques, and litigation processes and procedures to perform their work. Forensic accountants
are also increasingly playing more proactive risk reduction roles by designing and performing
extended procedures as part of stat.

Could a cell survive by having just peripheral proteins on it’s membrane? Why?
Solution
Principal component of plasmamembrane are lipids , phospholipid and carbohydrate .
Phospholipid make good barrier between interior and exterior of cell . Phospholipid , cholestrol
expand range of temperature for normal functioning of membrane. So without Phospholipid it is
not possible that membrane survive .Peripheral protein only help in signal transduction and allow

Briefly discuss five criteria used to classify an organism as a multi.pdf
Briefly discuss five criteria used to classify an organism as a multicelled animal?
Solution
Organisms that consist of more than one cell are known as multicellular organisms. Multicelluar
organisms are made up of more than one cell. These cells identify and attach to each other to
form a multicellular organism. Most of the multicellular organisms are visible to the naked eye.
Organisms like plants, animals, and some algae from a single cell and they grow up into a
multicelled organism. Both prokaryotes and eukaryotes show multicellularity. True multicellular
organisms regenerate a whole organism from germ cells.
There are there theories to discuss the mechanisms by which multicellularity could have evolved.
Symbiotic Theory- Symbiotic theory states that the first multicellular organism arose from
symbiosis behaviour of different species of a single-celled organism, each performing different
functions. Such symbiotic relation ship is seen between clown fish and Riterri sea anemones.
The Cellularization Theory or The Syncytial Theory- The cellularization theory states a
unicellular organismwould have developed from membrane boundaries/partitions around each
nuclei from a single celled organisms with multiple nuclei. Protists like cliates and slime molds
have multiple nuclei supporting this theory.
The Colonial Theory- The colonial theory that the symbiosis of many organisms of the same
species led to the evolution of multicellular organisms. This theory was proposed by Haecked in
1874.Majority of multicellularity occurs as a consequence of the cells falling to separate
following the process of division. Example of this theory can be seen in multicellular protists like
Volvox, Eudorina.
Advantages of Multicellularity in organism are that multicellularity allows the organism to
exceed the size limits. Multicelluarity also permits in increasing the complexity of the organism
by allowing differentiation of numerous cellular lineages in an organism.
Animals are multicellular and move with the aid of cilia, flagella, or muscular organs based on
contractile proteins. They have organelles including a nucleus, but no chliorplasts or cell walls.
Animals acquire nutrients by ingestion.
They have multiple cell with mitochondria and they depend on other organisms for food
Biologists recognize 36 phyla in the animals kingdom.
Size-The size of animals ranges from a few celled organosm like the mesozoans to animals
weighing many tones like the blue whale.
Animals bodies- Bodies of animals are made of cells organized into tissues which perform
specific functions in most animals tissue are organized into complex organs, which form organ
systems.
Cell structure_ The animal cell contains organelles like the nucleus, mitochondria, Golgi
complex, ribosomes, endoplasmic reticulum, lysosomes, vacuoles, centrioles, cytoskeieton.
Animals are made up of many organs systems, that aids in performing specific functions that are
necessary for the survival of the organism.

Q. How do steroid hormones enter a cell and bring about change in ex.pdf
Q. How do steroid hormones enter a cell and bring about change in expression of genes in the
nucleus?
Solution
Steroid hormones are non-water soluble hormones. They are present in the blood bound to
specific protein carriers.
When they have to enter a cell they dissociate from the protein carriers and enters the cell
through simple diffusion.
Once entering the cell these hormones bind to hormone receptor proteins present in the
cytoplasm and move as a hormone receptor complex into the nucleus where it encounters the
DNA. Binding of hormone to receptor protein changes its conformational structure making it
competent to bind DNA.
DNA inside the nucleus contains specific hormone response elements which recognises and
binds to DNA binding regions of intracellular receptor protein.
The receptor protein also contains region which interacts with transcription factors thus initiating
transcription at hormone response elements of DNA.
After transcription the mRNA moves to cytoplasm where specific proteins are synthesized
through translation..
Provide an in depth description of biological information transfer (.pdf
Provide an in depth description of biological information transfer (what is the chemistry
underlying each information transfer event, which nucleotide sequences are involved etc.)
Solution
The genetic information is stored in Deoxyribonucleic acid,DNA. DNA contains the information
needed to build an individual. Genetic information is transferred from DNA and converted to
protein.RNA molecules work as messengers.Proteins are the biological workers.Information of
the DNA is copied to a RNA molecule in transcription.RNA directs the protein synthesis in a
translation.Protein’s 3D structure determines it’s function.Information transfer only in one
direction.
The biological information flows from DNA to RNA,and from there to proteins.It is ultimately
the DNA that controls every function of the cell through protein synthesis.As a carrier of genetic
information,DNA in a cell must be duplicated (replicated),maintained and passed dawn
accurately to the daughter cells.
DNA is deoxyribonucleic acid,which is found in chromosomes, contains inherited
information,they are made up of nucleotides,and are what make up genes. A nucleotide is
composed of a sugar (deoxyribose),a phosphate group,and a base.There are 4 bases found in
DNA, Adenine (A),Thymine (T),Guanine (G),and Cytosine (C).Adenine and guanine are double
ring bases while thymine and cytosine are single ring bases.Nucleotides are joined to each other
by covalent bonds between the phosphate group of one nucleotide and the 3\' carbon atom of the
deoxyribose (sugar) of the next nucleotide.Each DNA molecule is unique because the order of
nucleotides is unique. The order of nucleotides determines the order of amino acids in a
protein.RNA is a nucleic acid composed of nucleotides and consists of one strand of
nucleotides.There are three different types of RNA- Ribosomal,Messenger,and
Transfer.Ribosomal RNA is the RNA molecules found in ribosomes. The large subunit RNA
contains the enzymatic activity that makes the peptide bonds between amino acids. Messenger
RNA is what controls the order of amino acids in a protein and determines which gene it codes
for.Transfer RNA brings amino acids to ribosomes.The transfer RNA has two recognition sites-
one recognizes an amino acid and the other recognizes one codon.The transfer RNA brings the
the correct amino acid to the ribosome.
Transcription is the process by which the information contained in a section of DNA is replicated
in the form of a newly assembled piece of messenger RNA (mRNA).Enzymes facilitating the
process include RNA polymerase and transcription factors.In eukaryotic cells the primary
transcript is pre-mRNA. Pre-mRNA must be processed for translation to proceed.Processing
includes the addition of a 5\' cap and a poly-A tail to the pre-mRNA chain,followed by
splicing.Alternative splicing occurs when appropriate, increasing the diversity of the proteins
that any single mRNA can produce.The product of the entire transcription process is a mature
mRNA ch.

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.

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
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
