Many biologists will talk about the group known as Ungulates, or hoo.pdf
Many biologists will talk about the group known as Ungulates, or hoofed mammals. This group
includes species as diverse as pigs (Sus), elk (Cervus), cows (Bos), hippos (Hippopotamus),
extinct species (e.g., Elomeryx and Archaeotherium), and even rhinos and horses (Equus). Based
upon the tree above and assuming this tree is correct, is this group (Ungulates) monophyletic?A.
Yes, because all of these species share the synapomorphy of hooves
Solution
b. Yes, because all of these species share a most recent common ancestor
All the members of the group of interest are more closely related to each other than they are to
the outgroup. Hence, the outgroup stems from the base of the tree. An outgroup can give you a
sense of where on the bigger tree of life the main group of organisms falls. It is also useful when
constructing evolutionary trees..

How are criminals maximizing their total utilitySolutionThe o.pdf
How are criminals maximizing their total utility?
Solution
The optimization function of criminals is like this:
Maximize Utility = U(Wealth accumulated from crimes), Subject to
\"Freedom\" Constraint = Minimum conviction
That is, they maximize utility by accumulating as much wealth they can from committing crimes,
subject to the constraint that they need to spend as less time in prisons (by avoiding being caught,
convicted and sentenced), since the more time they spend in prisons, the less they get time to
commit further crimes and gather wealth from such activities..

Help with my biostats Homework. Please show all work!! Mendel develo.pdf
Help with my biostats Homework. Please show all work!! Mendel developed his theory of
genetics by observing large numbers of offspring from particular parents during plant breeding
experiments. However, appropriate statistical methods for a rigorous analysis of such genetic
data were only invented about 50 years later, so Mendel basically said \"The data seem to agree
with Illy theory.\" Today, we can analyze Mendel\'s data statistically to see if he was right.
According to Mendel\'s theory, if pea plants heterozygous for the two traits of seed color and
seed texture are crossed, offspring will be produced with phenotypes in the following
proportions: Here are the actual data Mendel collected from an experiment crossing two such
parents: Use an appropriate statistical analysis to determine whether these data agree with
Mendel\'s theory. State the conclusion of your analysis clearly.
Solution
We use Goodness of Fit Test to do it.
The test hypothesis:
Ho: these data agree with Mendel\'s theory (i.e. null hypothesis)
Ha: these data do not agree with Mendel\'s theory (i.e. alternative hypothesis)observedexpectedO

for fiscal year 2006, the national debt of a country was approximate.pdf
for fiscal year 2006, the national debt of a country was approximately
(8.502 × 1018)
dollars. At that time, the number of citizens between the ages of 18 and 65 was known to be
(1.5 × 1012).
If the national debt of this country were divided evenly among these citizens, about how much
debt would be assigned to each individual? (Enter your answer in standard form, rounded to two
decimal places.)
$ per person
Solution
national debt of country=8.502*1018
number of citizens between age 18 and 65=1.5*1012
debt assigned to each individual = national debt of country/number of citizens between age 18
and 65
=(8.502*1018)/(1.5*1012) =5.702 dollars/person.

Discuss the relationships between competitive avantage, istinctive c.pdf
Discuss the relationships between competitive avantage, istinctive compentencies, resources,an
capabilities.
Solution
Resources
The activities and processes of the organization utilize certain assets. These assets are called
resources. These resources can be created within the organization. They form the internal
resources. Such generated resources are organization-specific. Otherwise they could be obtained
externally from the suppliers available in the resource markets. They form the external resources.
The externally obtained resources are organization-addressable. In addition resources can be
categorised as specific or non-specific. Those resources which can only be used for extremely
specialized intentions and are significant to the organization in adding value to goods and
services are called specific resources.
Resources
Resources of the firm can include all assets, capabilities, organizational processes, firm
attributes, information and knowledge. In short resources can be considered as inputs that
facilitate the organization to perform its activities.
All resources that an organization has may not have strategic relevance. Only certain resources
are capable of being an input to a value creating strategy which put the organization in a position
of competitive advantage. An organization’s resource should have four attributes to provide the
potential for competitive advantage. These form the VRIN characteristics.
The VRIN characteristics
The important features for a resource to be strategically important are as below
The VRIN characteristics mentioned above are individually necessary for the resources to be
valuable.
Non-specific resources are less specific and are less significant in adding value. Also resources
can be broadly classified as tangible and intangible. The physical assets that an organization
possesses are called tangible resources. The physical resources, human resources and final
resources come under this category.
The intellectual resources, technological resources and the organizational reputation together
form the intangible resources. The patents and copyrights of the organization are typical
examples of intellectual resources. The innovation capacity and innovation speed are examples
of technological resources. Reputation is basically good-will that the organization has acquired
among the customers. It is a critical resource of an organization.
Competencies
An organization should posses some characteristics in order to have the ability to compete with
other organizations in the market place. These characteristics form the competencies of the
organization. For any organization to survive in an industry competencies are must. At the same
time competencies cannot be useful to an organization when they stand alone. It is when they
combine together in the right combination that they help the organization to attain competitive
advantage. For instance consider an information technology organization. For this to compete in

Comparison of dysplasia and hyperplasiaSolutionDysplasia Dys.pdf
Comparison of dysplasia and hyperplasia?
Solution
Dysplasia: Dysplasia is a pre cancer, it is a term used in pathology to refer to an abnormality in
maturation of cells within a tissue, refers to an abnormal and potentially reversible process where
there is disordered growth and maturation of cells and the tissues and organs which they make
up.. This generally consists of an expansion of immature cells, with a corresponding decrease in
the number and location of mature cells. Dysplasia is often indicative of an early neoplastic
process. The term dysplasia is typically used when the cellular abnormality is restricted to the
originating tissue, as. For example, Myelodysplastic syndrome, or dysplasia of blood-forming
cells, show increased numbers of immature cells in the bone marrow, and a decrease in mature,
functional cells in the blood. Dysplasia can still be reversed if the factors that are responsible for
causing it are eliminated.
Hyperplasia: refer to the proliferation of cells within an organ or tissue beyond that which is
ordinarily seen. Hyperplasia may result in the gross enlargement of an organ, the formation of a
benign tumor, or may be visible only under a microscope, it is a general term for an increase in
the number of the cells of an organ or tissue causing it to increase in size. It may be due to any
number of causes such as increased demand, chronic inflammatory response, hormonal
dysfunctions, or neoplasia. Hyperplasia is considered to be a physiological response to a specific
stimulus, and the cells of a hyperplastic growth remain subject to normal regulatory control
mechanisms..

Sorts.java
AthleteManagement.java
Class Diagram:
Athlete
The Athlete class implements the \"Serializable\" interface so that its object can be stored. (The
Serializable interface is defined in the \"java.io\" package.)
AthleteNameComparator
The AthleteNameComparator class implements the \"Comparator\" interface (The Comparator
interface is in \"java.util\" package.). It needs to define the following method that was an
inherited abstract method from Comparator interface:
public int compare(Object first, Object second)
(Note that you can also define:
public int compare(Athlete first, Athlete second)
instead by making the class implements Comparator.
If the first argument object has a last name lexicographically less than that of the second
argument, an int less than zero is returned. If the first argument object has a last name
lexicographically larger than that of the second argument, an int greater than zero is returned. If
their last names are same, then their first names should be compared. If they have same first and
last names, then 0 should be returned.
MedalCountComparator
The MedalCountComparator class implements the \"Comparator\" interface (The Comparator
interface is in \"java.util\" package.). It needs to define the following method that was an
inherited abstract method from Comparator interface:
public int compare(Object first, Object second)
(Note that you can also define:
public int compare(Athlete first, Athlete second)
instead by making the class implements Comparator.
If the first argument object has a larger gold medal count than that of the second argument, an int
less than zero is returned. If the first argument object has a smaller gold medal count than that of
the second argument, an int greater than zero is returned. If both gold medal counts are same,
then their silver medal counts should be compared. If both gold medal counts are same and also
silver medal counts are same, then their bronze counts should be compared. If all of gold, silver,
and bronze medal counts are same, then 0 should be returned.
Sorts
The Sorts class is a utility class that will be used to sort a list of Athlete objects. Sorting
algorithms are described in the algorithm note posted under Notes section of the course web site.
These algorithms sort numbers stored in an array. It is your job to modify it to sort objects stored
in an array list (or a vector).
The Sorts class object will never be instantiated. It must have the following methods:
public static void sort(ArrayList objects, Comparator)
Your sort method utilizes the compare method of the parameter Comparator object to sort. You
can use one of Selection sort or Insertion Sort.
AthleteManagement
The AthleteManagement class has a list of Ath.
Write a function to merge two doubly linked lists. The input lists ha.pdf
Write a function to merge two doubly linked lists. The input lists have their elements in sorted
order, from lowest to highest. The output list should also be sorted from lowest to highest. Your
algorithm should run in linear time on the length of the output list. Provide an algorithm for your
function Implement and show some samples of your running function
Solution
The algorithm for LinkedList MergeSort is as follows.
The trick in this algorithm is to use a local list to store the value which is pointing to the actual
list to be returned as a result of the function
Step1: START
Step2: GET inputs of list1 and list2
Step3: INITIALIZE mergelist
STEP4: SET mylist = mergelist
Step5: WHILE list1 OR list2 is EMPTY
DO
IF (list1 AND list2) are NOT EMPTY
IF list1.value > list2.value
mylist.next = list2
ELSE
mylist.next = list1
ELSE IF list1 is EMPTY
mylist.next = list2
ELSE
mylist.next = list1
Step6: RETURN mergelist
Step7: STOP

Why just one sperm can enter the secondary oocyteWhy just one s.pdf
Why just one sperm can enter the secondary oocyte?
Why just one sperm can enter the secondary oocyte?
Solution
Sperm fuses with the egg and fertilizes it. Normally only one sperm fuses with an egg and if
more than one sperm fuses this is called polyspermy.Development of the zygote usually stops if
polyspermy occurs and in most cases, the egg cell blocks polyspermy.
In polyspermy,multipolar or extra miotic spindles are formed which stop the fertilized egg
development by causing faulty segregation of chromosomes during cell division. The egg plasma
prevent polyspermy by depolarising the egg plasma membranes after the first sperm cell fuses
with the egg cell. Thus preventing further sperm from fusing, this is the primary block to
polyspermy.
The secondary block to polyspermy is by the cortical reaction within the egg cell . the fusion of
the sperm with an egg plasma membrane causes an increase in cytosolic calcium within the egg.
The calcium activates the egg to begin development, which initiates a cortical reaction that
releases various enzymes that change the structure of the outside layer of the egg. This hardens
the zona pellucida which prevents another sperm from binding to it..

what is economics
Solution
\"Economics is the study of people in the ordinary business of life.\"
-- Alfred Marshall
Economicsis the social science that describes the factors that determine the production,
distriution and consumption of goods and services.Economics is the study of how people choose
to use resources.Resources include the time and talent people have available, the land, buildings,
equipment, and other tools on hand, and the knowledge of how to combine them to create useful
products and services.
Important choices involve how much time to devote to work, to school, and to leisure, how many
dollars to spend and how many to save, how to combine resources to produce goods and
services, and how to vote and shape the level of taxes and the role of government.
Often, people appear to use their resources to improve their well-being. Well-being includes the
satisfaction people gain from the products and services they choose to consume, from their time
spent in leisure and with family and community as well as in jobs, and the security and services
provided by effective governments. Sometimes, however, people appear to use their resources in
ways that don\'t improve their well-being.
In short, economics includes the study of labor, land, and investments, of money, income, and
production, and of taxes and government expenditures. Economists seek to measure well-being,
to learn how well-being may increase over time, and to evaluate the well-being of the rich and
the poor. The most famous book in economics is the Inquiry into the Nature and Causes of The
Wealth of Nations written by Adam Smith, and published in 1776 in Scotland.
Although the behavior of individuals is important, economics also addresses the collective
behavior of businesses and industries, governments and countries, and the globe as a whole.
Microeconomics starts by thinking about how individuals make decisions. Macroeconomics
considers aggregate outcomes. The two points of view are essential in understanding most
economic phenomena..
What are the functions of database management software (DBMS) Name .pdf
What are the functions of database management software (DBMS)? Name some common
database management software.
Solution
Functions of Database Management Software are:-
1. Data Dictionary Management - where the DBMS stores definitions of the data elements and
their relationships. This function is used by DBMS to look up the required data component
structures and relationships.
2. Data Storage Management - This function is used for the storage of the data and related entry
forms, report definitions, procedural code, data validation rules, and structures that can handle
video and picture formats.
3. Security Management - sets rules that determine specific users that are allowed to access the
database through username and password provided to each user.
4. Multiuser Access Control - Data integrity and data consistency are the basis of this function.
Multiuser access control is a very useful tool in a DBMS, it enables multiple users to access the
database simultaneously without affecting the integrity of the database.
Some common DBMS systems are Oracle database, Microsoft SQL, SAP, MySQL, Teradata,
informix..

Task #1 Correcting Logic Errors in Formulas
Copy and compile the source file NumericTypes.java, run the program, and observe the output.
Some of the output is incorrect. You need to correct logic errors in the average formula and the
temperature conversion formula. The logic errors could be due to conversion between data types,
order of operations, or formula problems. The necessary formulas are
average = (score1+score2) / numberOfScores
C = 5/9 (F-32)
Make sure that the output makes sense before you continue. The average of 95 and 100 should be

Solution
Choice 4 is correct.
Reason: It can be seen from the image that both SIV and HIV emerged at a similar rate and pace
in ancient times and their local distribution shares similar levels of complexities. It can also be
noted that N type HIV1 is not closely related to O type HIV but represent a divisional subtype of
the main HIV-1 type. Also, it can be carefully noted in the initial part of the image that SIV had
already emerged in chimpanzees much before evolution of HIV types. However, futher evolution
of HIV from SIV can be easily traced back from chimpanzees to humans. Further, evolutionay
timelines and the image shows that HIV-1 group O and P are closely related and group A and B
of HIV-2 were transmitted to humans.
Thus, the information states that choice 4 is most correct..

Help with my biostats Homework. Please show all work!! Mendel develo.pdf
Help with my biostats Homework. Please show all work!! Mendel developed his theory of
genetics by observing large numbers of offspring from particular parents during plant breeding
experiments. However, appropriate statistical methods for a rigorous analysis of such genetic
data were only invented about 50 years later, so Mendel basically said \"The data seem to agree
with Illy theory.\" Today, we can analyze Mendel\'s data statistically to see if he was right.
According to Mendel\'s theory, if pea plants heterozygous for the two traits of seed color and
seed texture are crossed, offspring will be produced with phenotypes in the following
proportions: Here are the actual data Mendel collected from an experiment crossing two such
parents: Use an appropriate statistical analysis to determine whether these data agree with
Mendel\'s theory. State the conclusion of your analysis clearly.

for fiscal year 2006, the national debt of a country was approximate.pdf
for fiscal year 2006, the national debt of a country was approximately
(8.502 × 1018)
dollars. At that time, the number of citizens between the ages of 18 and 65 was known to be
(1.5 × 1012).
If the national debt of this country were divided evenly among these citizens, about how much
debt would be assigned to each individual? (Enter your answer in standard form, rounded to two
decimal places.)
$ per person
Solution
national debt of country=8.502*1018
number of citizens between age 18 and 65=1.5*1012
debt assigned to each individual = national debt of country/number of citizens between age 18
and 65
=(8.502*1018)/(1.5*1012) =5.702 dollars/person.

Solution
Resources
The activities and processes of the organization utilize certain assets. These assets are called
resources. These resources can be created within the organization. They form the internal
resources. Such generated resources are organization-specific. Otherwise they could be obtained
externally from the suppliers available in the resource markets. They form the external resources.
The externally obtained resources are organization-addressable. In addition resources can be
categorised as specific or non-specific. Those resources which can only be used for extremely
specialized intentions and are significant to the organization in adding value to goods and
services are called specific resources.
Resources
Resources of the firm can include all assets, capabilities, organizational processes, firm
attributes, information and knowledge. In short resources can be considered as inputs that
facilitate the organization to perform its activities.
All resources that an organization has may not have strategic relevance. Only certain resources
are capable of being an input to a value creating strategy which put the organization in a position
of competitive advantage. An organization’s resource should have four attributes to provide the
potential for competitive advantage. These form the VRIN characteristics.
The VRIN characteristics
The important features for a resource to be strategically important are as below
The VRIN characteristics mentioned above are individually necessary for the resources to be
valuable.
Non-specific resources are less specific and are less significant in adding value. Also resources
can be broadly classified as tangible and intangible. The physical assets that an organization
possesses are called tangible resources. The physical resources, human resources and final
resources come under this category.
The intellectual resources, technological resources and the organizational reputation together
form the intangible resources. The patents and copyrights of the organization are typical
examples of intellectual resources. The innovation capacity and innovation speed are examples
of technological resources. Reputation is basically good-will that the organization has acquired
among the customers. It is a critical resource of an organization.
Competencies
An organization should posses some characteristics in order to have the ability to compete with
other organizations in the market place. These characteristics form the competencies of the
organization. For any organization to survive in an industry competencies are must. At the same
time competencies cannot be useful to an organization when they stand alone. It is when they
combine together in the right combination that they help the organization to attain competitive
advantage. For instance consider an information technology organization. For this to compete in

Comparison of dysplasia and hyperplasiaSolutionDysplasia Dys.pdf
Comparison of dysplasia and hyperplasia?
Solution
Dysplasia: Dysplasia is a pre cancer, it is a term used in pathology to refer to an abnormality in
maturation of cells within a tissue, refers to an abnormal and potentially reversible process where
there is disordered growth and maturation of cells and the tissues and organs which they make
up.. This generally consists of an expansion of immature cells, with a corresponding decrease in
the number and location of mature cells. Dysplasia is often indicative of an early neoplastic
process. The term dysplasia is typically used when the cellular abnormality is restricted to the
originating tissue, as. For example, Myelodysplastic syndrome, or dysplasia of blood-forming
cells, show increased numbers of immature cells in the bone marrow, and a decrease in mature,
functional cells in the blood. Dysplasia can still be reversed if the factors that are responsible for
causing it are eliminated.
Hyperplasia: refer to the proliferation of cells within an organ or tissue beyond that which is
ordinarily seen. Hyperplasia may result in the gross enlargement of an organ, the formation of a
benign tumor, or may be visible only under a microscope, it is a general term for an increase in
the number of the cells of an organ or tissue causing it to increase in size. It may be due to any
number of causes such as increased demand, chronic inflammatory response, hormonal
dysfunctions, or neoplasia. Hyperplasia is considered to be a physiological response to a specific
stimulus, and the cells of a hyperplastic growth remain subject to normal regulatory control
mechanisms..

AthleteManagement.java
Class Diagram:
Athlete
The Athlete class implements the \"Serializable\" interface so that its object can be stored. (The
Serializable interface is defined in the \"java.io\" package.)
AthleteNameComparator
The AthleteNameComparator class implements the \"Comparator\" interface (The Comparator
interface is in \"java.util\" package.). It needs to define the following method that was an
inherited abstract method from Comparator interface:
public int compare(Object first, Object second)
(Note that you can also define:
public int compare(Athlete first, Athlete second)
instead by making the class implements Comparator.
If the first argument object has a last name lexicographically less than that of the second
argument, an int less than zero is returned. If the first argument object has a last name
lexicographically larger than that of the second argument, an int greater than zero is returned. If
their last names are same, then their first names should be compared. If they have same first and
last names, then 0 should be returned.
MedalCountComparator
The MedalCountComparator class implements the \"Comparator\" interface (The Comparator
interface is in \"java.util\" package.). It needs to define the following method that was an
inherited abstract method from Comparator interface:
public int compare(Object first, Object second)
(Note that you can also define:
public int compare(Athlete first, Athlete second)
instead by making the class implements Comparator.
If the first argument object has a larger gold medal count than that of the second argument, an int
less than zero is returned. If the first argument object has a smaller gold medal count than that of
the second argument, an int greater than zero is returned. If both gold medal counts are same,
then their silver medal counts should be compared. If both gold medal counts are same and also
silver medal counts are same, then their bronze counts should be compared. If all of gold, silver,
and bronze medal counts are same, then 0 should be returned.
Sorts
The Sorts class is a utility class that will be used to sort a list of Athlete objects. Sorting
algorithms are described in the algorithm note posted under Notes section of the course web site.
These algorithms sort numbers stored in an array. It is your job to modify it to sort objects stored
in an array list (or a vector).
The Sorts class object will never be instantiated. It must have the following methods:
public static void sort(ArrayList objects, Comparator)
Your sort method utilizes the compare method of the parameter Comparator object to sort. You
can use one of Selection sort or Insertion Sort.
AthleteManagement
The AthleteManagement class has a list of Ath.

IF (list1 AND list2) are NOT EMPTY
IF list1.value > list2.value
mylist.next = list2
ELSE
mylist.next = list1
ELSE IF list1 is EMPTY
mylist.next = list2
ELSE
mylist.next = list1

Why just one sperm can enter the secondary oocyteWhy just one s.pdf
Why just one sperm can enter the secondary oocyte?
Why just one sperm can enter the secondary oocyte?
Solution
Sperm fuses with the egg and fertilizes it. Normally only one sperm fuses with an egg and if
more than one sperm fuses this is called polyspermy.Development of the zygote usually stops if
polyspermy occurs and in most cases, the egg cell blocks polyspermy.
In polyspermy,multipolar or extra miotic spindles are formed which stop the fertilized egg
development by causing faulty segregation of chromosomes during cell division. The egg plasma
prevent polyspermy by depolarising the egg plasma membranes after the first sperm cell fuses
with the egg cell. Thus preventing further sperm from fusing, this is the primary block to
polyspermy.
The secondary block to polyspermy is by the cortical reaction within the egg cell . the fusion of
the sperm with an egg plasma membrane causes an increase in cytosolic calcium within the egg.
The calcium activates the egg to begin development, which initiates a cortical reaction that
releases various enzymes that change the structure of the outside layer of the egg. This hardens
the zona pellucida which prevents another sperm from binding to it..

what is economics
Solution
\"Economics is the study of people in the ordinary business of life.\"
-- Alfred Marshall
Economicsis the social science that describes the factors that determine the production,
distriution and consumption of goods and services.Economics is the study of how people choose
to use resources.Resources include the time and talent people have available, the land, buildings,
equipment, and other tools on hand, and the knowledge of how to combine them to create useful
products and services.
Important choices involve how much time to devote to work, to school, and to leisure, how many
dollars to spend and how many to save, how to combine resources to produce goods and
services, and how to vote and shape the level of taxes and the role of government.
Often, people appear to use their resources to improve their well-being. Well-being includes the
satisfaction people gain from the products and services they choose to consume, from their time
spent in leisure and with family and community as well as in jobs, and the security and services
provided by effective governments. Sometimes, however, people appear to use their resources in
ways that don\'t improve their well-being.
In short, economics includes the study of labor, land, and investments, of money, income, and
production, and of taxes and government expenditures. Economists seek to measure well-being,

4. Add a line that prints out the value of fullName and how many characters
(including the space) are in the string stored in fullName (use the length
method to obtain that information).
5. Compile, debug, and run. The new output added on after the output from the
previous tasks should have your initials and your full name in uppercase

Task #4 UsingPredefined Math Functions
Add a line that prompts the user to enter the diameter of a sphere.
Read in and store the number into a variable called diameter (you will need to declare any
variables that you use).
The diameter is twice as long as the radius, so calculate and store the radius in an appropriately
named variable.
The formula for the volume of a sphere is
r3
Convert the formula to Java and add a line which calculates and stores the value of volume in an
appropriately named variable. Use Math.PI for and Math.pow to cube the radius.
Print your results to the screen with an appropriate message.
Compile, debug, and run using the following test data and record the resu.

Solution
Choice 4 is correct.
Reason: It can be seen from the image that both SIV and HIV emerged at a similar rate and pace
in ancient times and their local distribution shares similar levels of complexities. It can also be
noted that N type HIV1 is not closely related to O type HIV but represent a divisional subtype of
the main HIV-1 type. Also, it can be carefully noted in the initial part of the image that SIV had
already emerged in chimpanzees much before evolution of HIV types. However, futher evolution
of HIV from SIV can be easily traced back from chimpanzees to humans. Further, evolutionay
timelines and the image shows that HIV-1 group O and P are closely related and group A and B
of HIV-2 were transmitted to humans.
Thus, the information states that choice 4 is most correct..

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.

Introduction to Quality Improvement Essentials
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

How to Break the cycle of negative Thoughts
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
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.
