As a software developer you have been delegated with the assignment .pdf
As a software developer you have been delegated with the assignment of developing a software
“Library Management System” for an educational institute to manage their books. Elaborate the
different tasks you will undertake at each step of the software development lifecycle to develop
an efficient software
Solution
There are basically three phases in developing this LIbrary Management System .They are:
1)Project Initiation
2)Project execution
3)Release and usage (deploying)
1) PROJECT INITIATION : This is the Starting pahse of the project.Here the requirements are
gathered and the scope and cost of executing the project are known.This is known for deciding
whether the project should be developed or not.
2)PROJECT EXECUTION
In this phase the development or execution of the project takes place. Here we will try to build
up the project.
In this we have three sub-phases they are:
A. system analysis
• Initial study: The details about the project are known.
• Information gathering:The components or tools required to build up the project are
gathered.EX:Programming languages.
B. System design
• Design standard
• High level design & design tools
• Database design
• Logical design
• Construction
3. System implementation
• Integration & testing : Here all the individual build up phases are combined and are developed
into a totally functional system and are thouroughly tested.
• Post implementation :This is generally the BEta testing or USer Acceptence testing phase,This
is done after the entire project is implemented.
3)PROJECT DEPLOYMENT
In this phase the project is ready for work.It is deployed and is used.
After all these phases MAINTENANCE phase takes place.In MAINTENANCE phase any faults
which are found in the system will be solved..

Why do countries with high GNI and GDP are attractive for foreign in.pdf
Why do countries with high GNI and GDP are attractive for foreign investment?
Solution
Let us first understand what is a GNI and GDP
The gross national income (GNI) is the total domestic and foreign output claimed by residents of
a country, consisting of gross domestic product (GDP) plus factor incomes earned by foreign
residents, minus income earned in the domestic economy by nonresidents
Gross Domestic Product (GDP) is the broadest quantitative measure of a nation\'s total economic
activity. More specifically, GDP represents the monetary value of all goods and services
produced within a nation\'s geographic borders over a specified period of time.
The gross domestic product (GDP) is one of the primary indicators used to gauge the health of a
country\'s economy. It represents the total dollar value of all goods and services produced over a
specific time period; you can think of it as the size of the economy. Usually, GDP is expressed as
a comparison to the previous quarter or year. For example, if the year-to-year GDP is up 3%, this
is thought to mean that the economy has grown by 3% over the last year.
Measuring GDP is complicated (which is why we leave it to the economists), but at its most
basic, the calculation can be done in one of two ways: either by adding up what everyone earned
in a year (income approach), or by adding up what everyone spent (expenditure method).
Logically, both measures should arrive at roughly the same total.
Both the factors reflects the following ; and are most important in attracting foreign investments
In other words ,it determine the health of the any given economy ,and therefore is an important
yardstick to assess and measure and invest.
Which of the following is NOT true about the ESCBA.It acts as an.pdf
Which of the following is NOT true about the? ESCB?
A.It acts as an independent monetary authority.
B.It is an abbreviation for the European System of Central Banks.
C.Any one country can exert veto power over monetary policy.
D.It includes European Central Bank
Solution
A) It acts as an independent monetary authority. This is not true for ESCB as it consists of ECB
and 28 state national central banks. So the ESCB is not a monetary authority and also many EU
states having national banks have not joined euro..
What is 4 -4 + infinity - infinity As x approaches 3 from th.pdf
What is 4 -4 + infinity - infinity As x approaches 3 from the right (i.e. 3) the values are just
bigger that 3. So the denominator is positive and approaching 0. Hence the limit is going to +
infinity. Had the denominator been (3 - x) then the answer would have been - infinity.
Solution
c) +infinity if x approaches from 3+ then it will always be less than 3 ,suppose
x=3.00001 then the difference = 3-3.00001 = -.00001 hence when denominator is 3-x it will
always tend to (-infinity).
Use what you have learned so far to bring variety in your writing. U.pdf
Use what you have learned so far to bring variety in your writing. Use the following lines or your
own sheet of paper to write six sentences that practice each basic sentence pattern. When you
have finished, label each part of the sentence (S, V, LV, N, Adj, Adv, DO, IO).
1. ________________________________________________________________
2. ________________________________________________________________
3. ________________________________________________________________
4. ________________________________________________________________
5. ________________________________________________________________
6. ________________________________________________________________
Solution
The sentences you have encountered so far have been independent clauses. As you look more
closely at your past writing assignments, you may notice that some of your sentences are not
complete. A sentence that is missing a subject or a verb is called a fragment. A fragment may
include a description or may express part of an idea, but it does not express a complete thought.
Fragment: Children helping in the kitchen.
Complete sentence: Children helping in the kitchen often make a mess.
You can easily fix a fragment by adding the missing subject or verb. In the example, the sentence
was missing a verb. Adding often make a mess creates an S-V-N sentence structure. Figure 3.1
illustrates how you can edit a fragment to become a complete sentence.
Editing Fragments That Are Missing a Subject or a Verb
Fragment: Told her about the broken vase.
Complete sentence: I told her about the broken vase.
Complete sentence: The store down on Main Street sells music.
Common Sentence Errors
Fragments often occur because of some common errors, such as starting a sentence with a
preposition, a dependent word, an infinitive, or a gerund. If you use the six basic sentence
patterns when you write, you should be able to avoid these errors and thus avoid writing
fragments.
When you see a preposition, check to see that it is part of a sentence containing a subject and a
verb. If it is not connected to a complete sentence, it is a fragment, and you will need to fix this
type of fragment by combining it with another sentence. You can add the prepositional phrase to
the end of the sentence. If you add it to the beginning of the other sentence, insert a comma after
the prepositional phrase. Look at the examples. Figure 3.2 illustrates how you can edit a
fragment that begins with a preposition.
Example A:
[Incorrect: After walking over two miles. John remembered his wallet. Correct: After walking
over two miles, John remembered his wallet. Correct: John remembered his wallet after walking
over two miles.]
Example B:
[Incorrect: The dog growled at the vacuum cleaner. When it was switched on. Correct: When the
vacuum cleaner was switched on, the dog growled. Correct: The dog growled at the vacuum
cleaner when it was switched on.]
Clauses that start with a dependent word—such as since, because, without.

Transcription initiation and elongation
Solution
Transcription is the biochemical process involves transferring of information from DNA to
RNA, assisted with RNA polymerase. The RNA produced in this process will be converted to
protein in the process of translation. RNA polymerase read the DNA template and synthesize
with help of other important proteins to carried out the process. The process of transcription
comprises of series of events leading to Initiation, elongation, and termination. In the initiation
process, RNA polymerase with other adapter proteins binds to the upstream of DNA in the
initiation point.
RNA polymerase complexed with unwound DNA which bind to the promoter sequence, and
results in the initiation of the process. Promoter region contains an initiation site where process
begins. RNA polymerase synthesize new strand RNA, which is complementary to the DNA
strand.
In elongation phase, DNA polymerase lengthened the RNA, used as a DNA triplet code in the
template strand. polymerse read the template until the signal is percieved. RNA polymerase
functions by adding nucleotids to 3\' end of the strand and synthesized in 5\' to 3\' direction..

Thank you 1. What is responsible for anteriorposterior axis formati.pdf
Thank you 1. What is responsible for anterior:posterior axis formation in the chicken? How is
dorsal ventral patterning accomplished? 2. What is the role of the Posterior Marginal zone in
early chicken development? 3. What is the primitive streak and why is it important in chicken
development? 4. What is the function of Henson\'s Node? To what is it analogous in amphibian
development?
Solution
1.The primitive streak defines the axes of the embryo. It extends from posterior to anterior;
migrating cells enter through its dorsal side and move to its ventral side; and it separates the left
portion of the embryo from the right. Those elements close to the streak will be the medial
(central) structures, while those farther from it will be the distal (lateral) structures
2.Primitive streak is induced by the posterior marginal zone (PMZ) of Koller\'s sickle, which can
also induce Hensen\'s node. If cell movement in the PMZ is blocked, primitive streak does not
form.Thus, the PMZ acts as an organizer.Cells in marginal zones of the embryo, like the PMZ,
are key to development and cell fate determination in chick embryos.
3.The primitive streak is a structure that forms in the blastula during the early stages of avian,
reptilian and mammalian embryonic development. It forms on the dorsal (back) face of the
developing embryo, toward the caudal or posterior end.The presence of the primitive streak will
establish bilateral symmetry, determine the site of gastrulation and initiate germ layer formation.
To form the streak, reptiles, birds and mammals arrange mesenchymal cells along the
prospective midline, establishing the second embryonic axis, as well as the place where cells will
ingress and migrate during the process of gastrulation and germ layer formation.The primitive
streak extends through this midline and creates the left–right and cranial–caudal body axes,and
marks the beginning of gastrulation.This process involves the ingression of mesoderm
progenitors and their migration to their ultimate position,where they will differentiate into the
mesoderm germ layer that, together with endoderm and ectoderm germ layers, will give rise to
all the tissues of the adult organism.
4.
The primitive knot (or primitive node) is the organizer for gastrulation in the vertebrate embryo.
Diversity
In birds, it is known as \"Hensen\'s node\", and is named after its discoverer Victor Hensen.
In amphibians, it is known as \"Spemann\'s organizer\", and is named after Hans Spemann
In chick development, the primitive knot starts as a regional knot of cells that forms on the
blastodisc immediately anterior to where the outer layer of cells will begin to migrate inwards -
an area known as the primitive streak, which is involved with Koller\'s sickle. Posterior to the
node is the primitive pit, where the cells of the epiblast (the upper layer of embryonic cells)
initially begin to invaginate. This invagination expands posteriorly into the primitive groove as
the cells layers c.

Take the basic Hardy-Weinberg Equilibrium equation, where there are alleles A and B. If the
frequency of the two alleles are represented by p and q, then the expected genotypic frequencies
are p2 2pq q2. Please review your comfort with calculating observed and expected allele and
genotype frequencies. Try adding subscripts to the equation for relative fitness (use w) to predict
change in allele frequency due to selection. Both inbreeding and genetic drift can cause problems
for rare species with declining population size due to reducing genetic diversity. Please contrast
(say how they are different these two forces in terms of number of alleles at a locus (some loci
have more than two alleles) and in terms of average heterozygosity at a locus. In most organisms
most mating is local. If populations of an organism are scattered across a landscape, with gaps
between population, how will that affect inbreeding and expected Hardy Weinberg equilibrium?

P^2 = homozygous dominant
2pq =heterozygotes
Q^2= homozygous recessive
According to hardy Weinberg
P^2 +2pq + Q^2 =1
p = p2 + ½ (2pq) = p2 + pq
q = q2 + ½ (2pq) = q2 + pq
p + q = 1
(p + q)2 = 1
p2 + 2pq + q2 = 1 (the Hardy-Weinberg Principle)
Inbreeding can be referred as the mating between closely related organisms.
Inbreeding favors homozygosity, and increase q^2 (recessive homozygotes) and decreases
dominant phenotypes
It will increases the chances of offspring being affected by recessive or lethal traits.
Genetic bottlenecks and founder effects occurs in the population
Leads to
Hence population will be deviated from hardy-Weinberg equilibrium.
Systems analysis project 10 can you answer the 4 questions at the t.pdf
Systems analysis project 10: can you answer the 4 questions at the task section, thank you.
Personal Trainer, Inc. owns and operates fitness centers in a dozen Midwestern cities. The
centers have done well, and the company is planning an international expansion by opening a
new “supercenter” in the Toronto area. Personal Trainer’s president, Cassia Umi, hired an IT
consultant, Susan Park, to help develop an information system for the new facility. During the
project, Susan will work closely with Gray Lewis, who will manage the new operation.
Background
Susan and Gray finished their work on user interface, input, and output design. They developed
a user-centered design that would be flexible and easy to learn. Now Susan turned her attention
to the architecture for the new system. Susan wanted to consider their own organization and
culture, enterprise resource planning, total cost of ownership, scalability, Web integration, legacy
systems, processing methods, security issues, and corporate portal. She also needed to select a
network plan, or topology, that would dictate the physical cabling and network connections, or
consider a wireless network. When all these tasks were completed, she would submit a system
design specification for approval.
Tasks:
1. What would be the advantages of selecting an Internet-based architecture for the Personal
Trainer’s system?
2. If Personal Trainer wants to increase its Internet marketing efforts, what advice could you
offer? Perform research to find out more about the topic of Web-based marketing before you
answer Gray.
3. What software and hardware infrastructure will be necessary to ensure Personal Trainer can
process point of sale transactions?
4. Prepare an outline for a system design specification and describe the contents of each section
Solution

The Internet has had a colossal effect on system architecture modeling. The Internet has turn out
to be more than a communication channel — numerous IT onlookers see it as a in a far-reaching
way distinctive environment for system development. In a customary client/server system, the
client handles the user interface and the server (or servers in a multi-level framework) handles
the information and application rationale. As it were, a piece of the framework keeps running on
the customer, part on the server.
Interestingly, in an Internet-based architecture, notwithstanding information and application
rationale, the whole user interface is given by the Web server as HTML coded documents that
are deciphered and showed by the client\'s browser. Moving the obligation regarding the
interface from the client to the server improves the procedure of information transmission and
results in lower hardware’s expenses and complexities. The pattern toward Internet-based e-
business is reshaping the IT scene as additional firms utilize the Web to manufacture proficient,
solid, and practical arrangements. At the point when arranging new systems, experts can utilize
accessible.
Step 1. Read critically and analyze the following scenarioGeraldi.pdf
Step 1. Read critically and analyze the following scenario:
Geraldine Barney Garrett, the granddaughter of Wilford Barney took over the reins of the R&D
department of Biotech Health and Life Products (Biotech) in 1965. She had trained at the hands
of her grandmother Wilford’s mother, Maria. Geraldine was a strong manager and developed the
Research and Development (R&D) lab from the advanced kitchen of her grandmother to the
scientific lab of her peers. Geraldine’s management philosophy evolved over the years but she
had several basic ideas that kept her grounded. Geraldine knew she had to answer to the family
in every decision she made. Her grandmother stressed this point and she eventually came to
agree. Therefore, decisions were made by her. She also realized that her employees had good
ideas and talent but they did not bear the responsibility she did. So, although she consulted with
the employees often, she never gave them the power to make important decisions.
Geraldine was charismatic in a motherly way and employees saw her as someone to learn from
but career growth was unlikely so in five or six years employees moved on to another company.
The unambitious stayed on and eventually Geraldine collected a small group of people she
trusted and who became her team. Now, several of the team members are retiring like Geraldine
leaving few left to the company.
When it comes to leading the entire R&D Division, Geraldine is very controlled in defining
goals, setting tasks, and is outstanding at dividing the work among the employees, organizing the
product materials and coordinating and communicating activities between the different
departments. Decisions that Geraldine makes are always dependent on the circumstances and
context of the decision. You often hear her instructing the young employees stating, “Always ask
yourself, which method will work best here? Remember, you are always looking to find the
simplest and most cost-effective solution.” When it comes to developing new products and
innovating, Geraldine is much more open to other people’s input and ideas relying heavily on her
team of experienced but older people. Still, the final decision remains in her hands.
Geraldine could see the need for changes in the lab, the most important of which was retaining
younger employees. Since she was retiring at the end of the year, Geraldine knew the new
department head would have to deal with the problem. Her immediate concern was who the new
department head should be. Her own granddaughter, Melanie Malone, was now working in the
company and she knew Melanie was expecting the job.
Melanie was qualified for the job. She was a Phi Beta Kappa graduate of the University of
Maryland College Park with a double major in Botany and Food Science. She minored in
Business Management. She had worked in the plant in Chicago every summer since High School
and had reproduced and revised all her grandmother’s and great-great grandmother’s recipes.

Question 3 2 pts In response to the Great Recession, the Federal Rese.pdf
Question 3 2 pts In response to the Great Recession, the Federal Reserve engaged in quantitative
easing. As a consequence, the monetary base rose by nearly 400%, causing some to worry about
inflation. However, during this time the money supply rose by only 110%. What explains this? A
money multiplier greater than 1. A money multiplier equal to 1. A money multiplier smaller than
1. A negative money multiplier.
Solution
Money multiplier = Money supply / monetary base = 110 / 400 = 0.275
A money multiplier smaller than 1.

Microscopes and telescopes both consist of two converging lenses cont.pdf
Microscopes and telescopes both consist of two converging lenses contained in a tube. What is
the difference in set-up of the two lenses between a microscope and a telescope? The rearview
mirror on a truck warns the user that objects may be closer than they appear. What kind of mirror
is being used, and why was that type selected? Why does a clear stream always appear to be
shallower than it actually is? Discuss the type of aberration involved in each of the following
situations. (i) The edges of the image appear reddish. (ii) The image cannot be clearly focused.
A baby fish has his eyesight tested and is found to be myopic. His father wants to make a set of
glasses to correct for this problem. Since fish live under water, the father fish will make the
glasses out of a very thin clear plastic bag which is filled with air (n = 1.000). What type of lens
does the fish need to make? What shape should the lens be? What is the wavelength of yellow
light?
Solution
In refracting telescopes, there are typically two convex lenses. One lens acts as the objective
lens: this lens gathers light from faraway objects and forms a real, inverted image of the object at
its focal point. A second lens, called the eyepiece, is positioned such that the image formed by
the objective lens is at its focal point. When an observer looks through the eyepiece with a
relaxed eye, they are able to see an object of the image, formed at infinity. Microscopes are used
to look at magnified images of small objects. A simple microscope (a “magnifying glass”)
consists of a single convex lens. The lens is held close to the object so that the object is between
the lens and its focal point. When viewed from the other side of the lens, a magnified, virtual,
upright image is seen. The compound microscope is the most common type of microscope used
in laboratories. With these microscopes, an objective lens is used to create an inverted, real
image of the object. Using the eyepiece, the image is magnified. In this sense, its operating
principles are similar to that of a refracting telescope. The rear view mirror is a convex mirror
which forms a virtual and erect image of the object which is smaller in length than the object.
Because the image formed is smaller in length, it appears to be farther away and hence, the
warning written on it. This is because of the phenomenon of refraction of light as it crosses the
medium of water(refractive index greater than that of air). As the light ray travels from
water(denser medium) to air(rarer medium), the light ray bends away from the normal and the
image of the bottom of the stream seems to be raised and hence, the stream appears to be
shallower. a) In optics, chromatic aberration (CA, also called chromatic distortion, and
spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to
focus all colors to the same convergence point. It occurs because lenses have different refractive
indices for differentwavelength.

IPv6 was developed to correct the limitation inherent in IPv4. What .pdf
IPv6 was developed to correct the limitation inherent in IPv4. What are the areas that IPv5
improved on?
Solution
Firstly there is no version 5 for Internet protocol. IPV6 is definitely developed to overcome the
limitations of IPV4. Most important limitation is address depletion problem. IPv4 provided 32
bit addressing which means that there will be 232 different and unique addresses that can be
granted to the users of the internet, which is been classified into classes A,B,C,D and E out of
which A,B,C are granted based on the requirement from large scale to small scale. The classful
addressing was the main cause of the address depletion.To overcome that classless addressing
was intoduced,NAT was introduced which could not rectify the problem completely. Therefore
IPV6 was developed to satify the requirements of growing internet population. IPV6 has 128 bit
addressing which can assign 2128 unique addresses which is far bigger than IPV4.
Apart from this IPV6 has simple header when compared to IPV4, with IPV6 the routing is more
effective and it also provides authentication which is part of security, which is another main
drawback in IPV4(it is unreliable)..

In each of the following situations, identify one or more ways that .pdf
In each of the following situations, identify one or more ways that cultural differences may be
leading to miscommunication.
1. Alan is a U.S. sales representative in South America. He makes appointments and is careful to
be on time. But the person he’s calling on is frequently late. To save time, Alan tries to get right
to business. But his hosts want to talk about sightseeing and his family. Even worse, his
appointments are interrupted constantly, not only by business phone calls but also by long
conversations with other people and even the customers’ children who come into the office.
Alan’s first progress report is very negative. He hasn’t yet made a sale. Perhaps South America
just isn’t the right place to sell his company’s products.
2. To help her company establish a presence in Asia, Susan wants to hire a local interpreter who
can advise her on business customs. Kana Tomari has superb qualifications on paper. But when
Susan tries to probe about her experience, Kana just says, “I will do my best. I will try very
hard.” She never gives details about any of the previous positions she’s held. Susan begins to
wonder if the re?sume? is inflated.
3. Stan wants to negotiate a joint venture with an Asian company. He asks Tung-Sen Lee if the
people have enough discretionary income to afford his product. Mr. Lee is silent for a time, and
then says, “Your product is good. People in the West must like it.” Stan smiles, pleased that Mr.
Lee recognizes the quality of his product, and he gives Mr. Lee a contract to sign. Weeks later,
Stan still hasn’t heard anything. If Asians are going to be so non-responsive, he wonders if he
really should try to do business with them.
4. Elspeth is very proud of her participatory management style. On assignment in India, she is
careful not to give orders but to ask for suggestions. But people rarely suggest anything. Even a
formal suggestion system doesn’t work. And to make matters worse, she doesn’t sense the
respect and camaraderie of the plant she man- aged in the United States. Perhaps, she decides
gloomily, people in India just aren’t ready for a woman boss.
Solution
Answer for 1)
The difference of culture in between Alan and his hosts is that his hosts want to talk about
sightseeing and his family which are matter related to some thing personal but Alan want to go to
the business straightly.Along with it Alan is not getting any thing that he expects like punctuality
from his customers but that what he is not getting which leaded to miscommunication.
Answer for 2)
Here,Kana Tomari as she looked great on the paper she really may bcapable.Here, while in work
one person may not reach the expectation of other person and that what Kana Tomari wants to
say but when it comes to the view of Susan she want to see confidence in Kana Tomari that her
need will be definitely served that lead to miscommunication.

A variable helps us to identify the data. For ex: int a = 5; Here 5 is identified through variable a.
Now, if we have collection of integers, we need some representation to identify them. We call it
array. For ex: int arr[5]
This array is nothing but a Data Structure.
So, a Data Structure is a way to group the data.
There are many Data Structures available like Arrays, Linked List, Doubly-Linked list, Stack,
Queue, etc.
Doubly-Linked list are the ones where you can traverse from the current node both in left and
right directions.
Why so many different types of Data Structures are required ?
Answer is very simple, grouping of data, storage of data and accessing the data is different.
For example, in case of Arrays we store all the data in contiguous locations.
What if we are not able to store the data in contiguous locations because we have huge data.
Answer is go for Linked List/Doubly-Linked list.
Here we can store the data anywhere and link the data through pointers.
I will try to provide comments for the code you have given. May be this can help you.

How to secure information systemsSolutionAnswerInformation.pdf
How to secure information systems?
Solution
Answer:
Information security:
Information security, sometimes shortened to InfoSec, is the practice of halting unauthorized
access, use, revelation, disordering, modification, investigation, recording or destruction of
information. It is a general term that can be used regardless of the form the data may take (e.g.
electronic, physical).
Since the advent of the internet and increased expansion of computer based technology in
today\'s corporations, information security breaches have increased at an alarming rate. While
businesses take a more cautious approach to how they handle IT security threats, these are
becoming increasingly complex and sophisticated. Denial-of-service attacks, software tampering
(e.g. Trojan horses and computer viruses) and social engineering techniques (e.g. phishing) are
some examples becoming prevalent. While we often times hear of the more widely publicized
embezzlement, money laundering, burglary and bribery statistics, data has shown that companies
have seen greater losses from losses attributed to information security breaches.
One of the most effective ways to prevent criminals from accessing and compromising
confidential company information is to implement an effective information security plan and
properly train firm employees accessing the system. Additionally, companies should implement
a dynamic and independent third party auditor to frequently test the adequacy of their security
system. Lastly, key responsibilities within the information security chain should be segregated
and rotated frequently. If companies follow these three basic tenets, they will be one step closer
to the effective security of their information.
Threats to Information Systems:
Information security threats come in many different forms. Some of the most common threats
today are software attacks, theft of intellectual property, identity theft, theft of equipment or
information, sabotage, and information infiltration Some of the most prevalent types of data
infiltration include input manipulation, program manipulation, data input manipulation, data
stealing, and outright sabotage. The most frequent type associated with this form of fraud is
manipulation of the data. The reason for this most common is because the criminal requires the
less amount of skill.
Most people have experienced software attacks of some sort. Viruses, worms, phishing
attacks, and Trojan horses are a few common examples of software attacks. Governments,
military, corporations, financial institutions, hospitals and private businesses amass a great deal
of confidential information about their employees, customers, products, research and financial
status. Most of this information is now collected, processed and stored on electronic computers
and transmitted across networks to other computers.

With so many different ways and so much potential for breaches to information security

Solution
Answer is (d).
Independent variable is the teaching method
Dependent variable is the social skills that are learned.
Explanation:
Since, the social skills learned are always dependent on the training method used on the autistic
child. But since we are comparing training methods and also the question has very limited
information about the autistic children, so, training method is independent variable..

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.

Transcription initiation and elongation
Solution
Transcription is the biochemical process involves transferring of information from DNA to
RNA, assisted with RNA polymerase. The RNA produced in this process will be converted to
protein in the process of translation. RNA polymerase read the DNA template and synthesize
with help of other important proteins to carried out the process. The process of transcription
comprises of series of events leading to Initiation, elongation, and termination. In the initiation
process, RNA polymerase with other adapter proteins binds to the upstream of DNA in the
initiation point.
RNA polymerase complexed with unwound DNA which bind to the promoter sequence, and
results in the initiation of the process. Promoter region contains an initiation site where process
begins. RNA polymerase synthesize new strand RNA, which is complementary to the DNA
strand.
In elongation phase, DNA polymerase lengthened the RNA, used as a DNA triplet code in the
template strand. polymerse read the template until the signal is percieved. RNA polymerase
functions by adding nucleotids to 3\' end of the strand and synthesized in 5\' to 3\' direction..

Thank you 1. What is responsible for anteriorposterior axis formati.pdf
Thank you 1. What is responsible for anterior:posterior axis formation in the chicken? How is
dorsal ventral patterning accomplished? 2. What is the role of the Posterior Marginal zone in
early chicken development? 3. What is the primitive streak and why is it important in chicken
development? 4. What is the function of Henson\'s Node? To what is it analogous in amphibian
development?
Solution
1.The primitive streak defines the axes of the embryo. It extends from posterior to anterior;
migrating cells enter through its dorsal side and move to its ventral side; and it separates the left
portion of the embryo from the right. Those elements close to the streak will be the medial
(central) structures, while those farther from it will be the distal (lateral) structures
2.Primitive streak is induced by the posterior marginal zone (PMZ) of Koller\'s sickle, which can
also induce Hensen\'s node. If cell movement in the PMZ is blocked, primitive streak does not
form.Thus, the PMZ acts as an organizer.Cells in marginal zones of the embryo, like the PMZ,
are key to development and cell fate determination in chick embryos.
3.The primitive streak is a structure that forms in the blastula during the early stages of avian,
reptilian and mammalian embryonic development. It forms on the dorsal (back) face of the
developing embryo, toward the caudal or posterior end.The presence of the primitive streak will
establish bilateral symmetry, determine the site of gastrulation and initiate germ layer formation.
To form the streak, reptiles, birds and mammals arrange mesenchymal cells along the
prospective midline, establishing the second embryonic axis, as well as the place where cells will
ingress and migrate during the process of gastrulation and germ layer formation.The primitive
streak extends through this midline and creates the left–right and cranial–caudal body axes,and
marks the beginning of gastrulation.This process involves the ingression of mesoderm
progenitors and their migration to their ultimate position,where they will differentiate into the
mesoderm germ layer that, together with endoderm and ectoderm germ layers, will give rise to
all the tissues of the adult organism.
4.
The primitive knot (or primitive node) is the organizer for gastrulation in the vertebrate embryo.
Diversity
In birds, it is known as \"Hensen\'s node\", and is named after its discoverer Victor Hensen.
In amphibians, it is known as \"Spemann\'s organizer\", and is named after Hans Spemann
In chick development, the primitive knot starts as a regional knot of cells that forms on the
blastodisc immediately anterior to where the outer layer of cells will begin to migrate inwards -
an area known as the primitive streak, which is involved with Koller\'s sickle. Posterior to the
node is the primitive pit, where the cells of the epiblast (the upper layer of embryonic cells)
initially begin to invaginate. This invagination expands posteriorly into the primitive groove as
the cells layers c.

Take the basic Hardy-Weinberg Equilibrium equation, where there are alleles A and B. If the
frequency of the two alleles are represented by p and q, then the expected genotypic frequencies
are p2 2pq q2. Please review your comfort with calculating observed and expected allele and
genotype frequencies. Try adding subscripts to the equation for relative fitness (use w) to predict
change in allele frequency due to selection. Both inbreeding and genetic drift can cause problems
for rare species with declining population size due to reducing genetic diversity. Please contrast
(say how they are different these two forces in terms of number of alleles at a locus (some loci
have more than two alleles) and in terms of average heterozygosity at a locus. In most organisms
most mating is local. If populations of an organism are scattered across a landscape, with gaps
between population, how will that affect inbreeding and expected Hardy Weinberg equilibrium?

P^2 = homozygous dominant
2pq =heterozygotes
Q^2= homozygous recessive
According to hardy Weinberg
P^2 +2pq + Q^2 =1
p = p2 + ½ (2pq) = p2 + pq
q = q2 + ½ (2pq) = q2 + pq
p + q = 1
(p + q)2 = 1
p2 + 2pq + q2 = 1 (the Hardy-Weinberg Principle)
Inbreeding can be referred as the mating between closely related organisms.
Inbreeding favors homozygosity, and increase q^2 (recessive homozygotes) and decreases
dominant phenotypes
It will increases the chances of offspring being affected by recessive or lethal traits.
Genetic bottlenecks and founder effects occurs in the population
Leads to
Hence population will be deviated from hardy-Weinberg equilibrium.
Systems analysis project 10 can you answer the 4 questions at the t.pdf
Systems analysis project 10: can you answer the 4 questions at the task section, thank you.
Personal Trainer, Inc. owns and operates fitness centers in a dozen Midwestern cities. The
centers have done well, and the company is planning an international expansion by opening a
new “supercenter” in the Toronto area. Personal Trainer’s president, Cassia Umi, hired an IT
consultant, Susan Park, to help develop an information system for the new facility. During the
project, Susan will work closely with Gray Lewis, who will manage the new operation.
Background
Susan and Gray finished their work on user interface, input, and output design. They developed
a user-centered design that would be flexible and easy to learn. Now Susan turned her attention
to the architecture for the new system. Susan wanted to consider their own organization and
culture, enterprise resource planning, total cost of ownership, scalability, Web integration, legacy
systems, processing methods, security issues, and corporate portal. She also needed to select a
network plan, or topology, that would dictate the physical cabling and network connections, or
consider a wireless network. When all these tasks were completed, she would submit a system
design specification for approval.
Tasks:
1. What would be the advantages of selecting an Internet-based architecture for the Personal
Trainer’s system?
2. If Personal Trainer wants to increase its Internet marketing efforts, what advice could you
offer? Perform research to find out more about the topic of Web-based marketing before you
answer Gray.
3. What software and hardware infrastructure will be necessary to ensure Personal Trainer can
process point of sale transactions?
4. Prepare an outline for a system design specification and describe the contents of each section

The Internet has had a colossal effect on system architecture modeling. The Internet has turn out
to be more than a communication channel — numerous IT onlookers see it as a in a far-reaching
way distinctive environment for system development. In a customary client/server system, the
client handles the user interface and the server (or servers in a multi-level framework) handles
the information and application rationale. As it were, a piece of the framework keeps running on
the customer, part on the server.
Interestingly, in an Internet-based architecture, notwithstanding information and application
rationale, the whole user interface is given by the Web server as HTML coded documents that
are deciphered and showed by the client\'s browser. Moving the obligation regarding the
interface from the client to the server improves the procedure of information transmission and
results in lower hardware’s expenses and complexities. The pattern toward Internet-based e-
business is reshaping the IT scene as additional firms utilize the Web to manufacture proficient,
solid, and practical arrangements. At the point when arranging new systems, experts can utilize

Step 1. Read critically and analyze the following scenarioGeraldi.pdf
Step 1. Read critically and analyze the following scenario:
Geraldine Barney Garrett, the granddaughter of Wilford Barney took over the reins of the R&D
department of Biotech Health and Life Products (Biotech) in 1965. She had trained at the hands
of her grandmother Wilford’s mother, Maria. Geraldine was a strong manager and developed the
Research and Development (R&D) lab from the advanced kitchen of her grandmother to the
scientific lab of her peers. Geraldine’s management philosophy evolved over the years but she
had several basic ideas that kept her grounded. Geraldine knew she had to answer to the family
in every decision she made. Her grandmother stressed this point and she eventually came to
agree. Therefore, decisions were made by her. She also realized that her employees had good
ideas and talent but they did not bear the responsibility she did. So, although she consulted with
the employees often, she never gave them the power to make important decisions.
Geraldine was charismatic in a motherly way and employees saw her as someone to learn from
but career growth was unlikely so in five or six years employees moved on to another company.
The unambitious stayed on and eventually Geraldine collected a small group of people she
trusted and who became her team. Now, several of the team members are retiring like Geraldine
leaving few left to the company.
When it comes to leading the entire R&D Division, Geraldine is very controlled in defining
goals, setting tasks, and is outstanding at dividing the work among the employees, organizing the
product materials and coordinating and communicating activities between the different
departments. Decisions that Geraldine makes are always dependent on the circumstances and
context of the decision. You often hear her instructing the young employees stating, “Always ask
yourself, which method will work best here? Remember, you are always looking to find the
simplest and most cost-effective solution.” When it comes to developing new products and
innovating, Geraldine is much more open to other people’s input and ideas relying heavily on her
team of experienced but older people. Still, the final decision remains in her hands.
Geraldine could see the need for changes in the lab, the most important of which was retaining
younger employees. Since she was retiring at the end of the year, Geraldine knew the new
department head would have to deal with the problem. Her immediate concern was who the new
department head should be. Her own granddaughter, Melanie Malone, was now working in the
company and she knew Melanie was expecting the job.
Melanie was qualified for the job. She was a Phi Beta Kappa graduate of the University of
Maryland College Park with a double major in Botany and Food Science. She minored in
Business Management. She had worked in the plant in Chicago every summer since High School
and had reproduced and revised all her grandmother’s and great-great grandmother’s recipes.

Microscopes and telescopes both consist of two converging lenses cont.pdf
Microscopes and telescopes both consist of two converging lenses contained in a tube. What is
the difference in set-up of the two lenses between a microscope and a telescope? The rearview
mirror on a truck warns the user that objects may be closer than they appear. What kind of mirror
is being used, and why was that type selected? Why does a clear stream always appear to be

situations. (i) The edges of the image appear reddish. (ii) The image cannot be clearly focused.
A baby fish has his eyesight tested and is found to be myopic. His father wants to make a set of
glasses to correct for this problem. Since fish live under water, the father fish will make the
glasses out of a very thin clear plastic bag which is filled with air (n = 1.000). What type of lens
does the fish need to make? What shape should the lens be? What is the wavelength of yellow
light?
Solution
In refracting telescopes, there are typically two convex lenses. One lens acts as the objective
lens: this lens gathers light from faraway objects and forms a real, inverted image of the object at
its focal point. A second lens, called the eyepiece, is positioned such that the image formed by
the objective lens is at its focal point. When an observer looks through the eyepiece with a
relaxed eye, they are able to see an object of the image, formed at infinity. Microscopes are used
to look at magnified images of small objects. A simple microscope (a “magnifying glass”)
consists of a single convex lens. The lens is held close to the object so that the object is between
the lens and its focal point. When viewed from the other side of the lens, a magnified, virtual,
upright image is seen. The compound microscope is the most common type of microscope used
in laboratories. With these microscopes, an objective lens is used to create an inverted, real
image of the object. Using the eyepiece, the image is magnified. In this sense, its operating
principles are similar to that of a refracting telescope. The rear view mirror is a convex mirror
which forms a virtual and erect image of the object which is smaller in length than the object.
Because the image formed is smaller in length, it appears to be farther away and hence, the
warning written on it. This is because of the phenomenon of refraction of light as it crosses the
medium of water(refractive index greater than that of air). As the light ray travels from
water(denser medium) to air(rarer medium), the light ray bends away from the normal and the
image of the bottom of the stream seems to be raised and hence, the stream appears to be
shallower. a) In optics, chromatic aberration (CA, also called chromatic distortion, and
spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to
focus all colors to the same convergence point. It occurs because lenses have different refractive
indices for differentwavelength.

IPv6 was developed to correct the limitation inherent in IPv4. What .pdf
IPv6 was developed to correct the limitation inherent in IPv4. What are the areas that IPv5
improved on?
Solution
Firstly there is no version 5 for Internet protocol. IPV6 is definitely developed to overcome the
limitations of IPV4. Most important limitation is address depletion problem. IPv4 provided 32
bit addressing which means that there will be 232 different and unique addresses that can be
granted to the users of the internet, which is been classified into classes A,B,C,D and E out of
which A,B,C are granted based on the requirement from large scale to small scale. The classful
addressing was the main cause of the address depletion.To overcome that classless addressing
was intoduced,NAT was introduced which could not rectify the problem completely. Therefore
IPV6 was developed to satify the requirements of growing internet population. IPV6 has 128 bit
addressing which can assign 2128 unique addresses which is far bigger than IPV4.
Apart from this IPV6 has simple header when compared to IPV4, with IPV6 the routing is more
effective and it also provides authentication which is part of security, which is another main
drawback in IPV4(it is unreliable)..
Japadog is the pioneer of street vending in Vancouver. They are uniq.pdf
Japadog is the pioneer of street vending in Vancouver. They are unique to Vancouver(they tried
to branch outin New York but apparently failed) and they sell “Japanese-style” hot-dogsin the
streets. They have a stand that serves a stretch of West Cordova. There’s only one licence, so
they do not decide how many stands to open. One stand. On any given day Japadog expects that
up to 100 visitors may want to buy their hot-dogs. They think that the Hotelling spatial model is
a good framework to make theirbusiness decision, and here are their estimates: the dog’s
reservation price is $9, a customer’s cost of traveling along West Cordova is $6/km, there are no
fixed costs, the stretch of West Cordova they serve is 1 km long, and they have a stand right in
the middle ofthatstretch. The cost of making the hotdogsis flat $6 per dog. 1. What is the profit-
maximizing price ($ per hot-dog)? 2. How many hot-dogs(per day) would Japadog sell? 3. What
profit will Japadog expect to make ($ per day)

First-rate proof of Mayor Sam Sullivan\'s political vulnerability
seem at all of the wannabes lining up for the 2008 mayoral contest. Two-time mayoral candidate
Jim inexperienced, NDP MLA Gregor Robertson, and councillors Raymond Louie and David
Cadman have not dominated themselves out of the race, which means that they may be in most
cases all involved in walking. Then there are the chronic rumours that NPA councillor Peter
Ladner additionally needs Sullivan\'s job. Former NPA mayors Gordon Campbell and Philip
Owen under no circumstances found themselves in Sullivan\'s situation a 12 months earlier than
they sought reelection, nevertheless it\'s most of the time nonetheless too early to put in writing
off the little bugger\'s political career. Sullivan has been underestimated many times earlier
thanâunder that boyish veneer beats the heart of a political cobra.
First-rate double dipping
The premier\'s former deputy minister, Ken Dobell, is a shoo-in. What are you able to say a few
man who contracts himself out as a provincial lobbyist (or \"content material guide\", as he put
it) for the town of Vancouver on housing issues whilst he has a desk in the premier\'s office as
Gordon Campbell\'s unique adviser? Dobell, a former Vancouver metropolis supervisor,
managed to duck controversy for a long time, regardless of taking part in a position in a couple
of critical public-policy errors. While he was CEO of TransLink, he was the actual father of the
Canada Line rapid-transit undertaking, which has compelled neighborhood firms into bankruptcy
and which might eventually do the same to TransLink. He has additionally been the preferable\'s
point man on the ever-extra-costly expansion of the Vancouver convention and Exhibition
Centre. It started out at $495 million but has when you consider that crossed the $800-million

In each of the following situations, identify one or more ways that .pdf
In each of the following situations, identify one or more ways that cultural differences may be
leading to miscommunication.
1. Alan is a U.S. sales representative in South America. He makes appointments and is careful to
be on time. But the person he’s calling on is frequently late. To save time, Alan tries to get right
to business. But his hosts want to talk about sightseeing and his family. Even worse, his
appointments are interrupted constantly, not only by business phone calls but also by long
conversations with other people and even the customers’ children who come into the office.
Alan’s first progress report is very negative. He hasn’t yet made a sale. Perhaps South America
just isn’t the right place to sell his company’s products.
2. To help her company establish a presence in Asia, Susan wants to hire a local interpreter who
can advise her on business customs. Kana Tomari has superb qualifications on paper. But when
Susan tries to probe about her experience, Kana just says, “I will do my best. I will try very
hard.” She never gives details about any of the previous positions she’s held. Susan begins to
wonder if the re?sume? is inflated.
3. Stan wants to negotiate a joint venture with an Asian company. He asks Tung-Sen Lee if the
people have enough discretionary income to afford his product. Mr. Lee is silent for a time, and
then says, “Your product is good. People in the West must like it.” Stan smiles, pleased that Mr.
Lee recognizes the quality of his product, and he gives Mr. Lee a contract to sign. Weeks later,
Stan still hasn’t heard anything. If Asians are going to be so non-responsive, he wonders if he
really should try to do business with them.
4. Elspeth is very proud of her participatory management style. On assignment in India, she is
careful not to give orders but to ask for suggestions. But people rarely suggest anything. Even a
formal suggestion system doesn’t work. And to make matters worse, she doesn’t sense the
respect and camaraderie of the plant she man- aged in the United States. Perhaps, she decides
gloomily, people in India just aren’t ready for a woman boss.
Solution
Answer for 1)
The difference of culture in between Alan and his hosts is that his hosts want to talk about
sightseeing and his family which are matter related to some thing personal but Alan want to go to
the business straightly.Along with it Alan is not getting any thing that he expects like punctuality
from his customers but that what he is not getting which leaded to miscommunication.
Answer for 2)
Here,Kana Tomari as she looked great on the paper she really may bcapable.Here, while in work
one person may not reach the expectation of other person and that what Kana Tomari wants to
say but when it comes to the view of Susan she want to see confidence in Kana Tomari that her
need will be definitely served that lead to miscommunication.
Answer for 3)
HereMr.lee just wanted to say that his prodect won\'t be succeed in Asian country and hence, he

cout<data<<\",\";
}
//add data to the front of the linked list
void add(struct node** head_ref, char data)
{
//create new node
struct node* newnode=new node();
//adding data
newnode->data = data;
//adding node to the front
newnode->next = (*head_ref);
//making new node head
(*head_ref) = newnode;
}
int main()
{
// create linked list a, b, c, d
struct node* head = NULL;

Data Structures in C++I am really new to C++, so links are really .pdf
Data Structures in C++
I am really new to C++, so links are really hard topic for me. It would be nice if you can provide
explanations of what doubly linked lists are and of some of you steps... Thank you
In this assignment, you will implement a doubly-linked list class, together with some list
operations. To make things easier, you’ll implement a list of int, rather than a template class.
Solution
A variable helps us to identify the data. For ex: int a = 5; Here 5 is identified through variable a.
Now, if we have collection of integers, we need some representation to identify them. We call it
array. For ex: int arr[5]
This array is nothing but a Data Structure.
So, a Data Structure is a way to group the data.
There are many Data Structures available like Arrays, Linked List, Doubly-Linked list, Stack,
Queue, etc.
Doubly-Linked list are the ones where you can traverse from the current node both in left and
right directions.
Why so many different types of Data Structures are required ?
Answer is very simple, grouping of data, storage of data and accessing the data is different.
For example, in case of Arrays we store all the data in contiguous locations.
What if we are not able to store the data in contiguous locations because we have huge data.
Answer is go for Linked List/Doubly-Linked list.
Here we can store the data anywhere and link the data through pointers.
I will try to provide comments for the code you have given. May be this can help you.
#pragma once
/*
dlist.h
Doubly-linked lists of ints
*/
#include
class dlist {
public:
dlist() { }
// Here we are creating a NODE, it has a integer value and two pointers.
// One pointer is to move to next node and other to go back to previous node.
struct node {
int value;
node* next;
node* prev;
};
// To return head pointer, i.e. start of the Doubly-Linked list.
node* head() const { return _head; }
// To return Tail pointer, i.e. end of the Doubly-Linked list.
node* tail() const { return _tail; }
// **** Implement ALL the following methods ****
// Returns the node at a particular index (0 is the head).
node* at(int index){
int cnt = 0;
struct node* tmp = head();
while(tmp!=NULL)
{
if (cnt+1 == index)
return tmp;
tmp = tmp->next;
}
}
// Insert a new value, after an existing one
void insert(node *previous, int value){
// check if the given previous is NULL
if (previous == NULL)
{
printf(\"the given previous node cannot be NULL\");
return;
}
// allocate new node
struct node* new_node =(struct node*) malloc(sizeof(struct node));
// put in the data
new_node->data = new_data;
// Make next of new node as next of previous
new_node->next = previous->next;
// Make the next of previous as new_node
previous->next = new_node;
// Make previous as previous of new_node
new_node->prev = previous;
// Change previous of new_node\'s next node
if (new_node->next != NULL)
new_node->next->prev = new_node;
}
// Delete the given node
void del(node* which){
struct node* head_ref = head();
/* base case */
if(*head_ref == NUL.
How to secure information systemsSolutionAnswerInformation.pdf
How to secure information systems?
Solution
Answer:
Information security:
Information security, sometimes shortened to InfoSec, is the practice of halting unauthorized
access, use, revelation, disordering, modification, investigation, recording or destruction of
information. It is a general term that can be used regardless of the form the data may take (e.g.
electronic, physical).
Since the advent of the internet and increased expansion of computer based technology in
today\'s corporations, information security breaches have increased at an alarming rate. While
businesses take a more cautious approach to how they handle IT security threats, these are
becoming increasingly complex and sophisticated. Denial-of-service attacks, software tampering
(e.g. Trojan horses and computer viruses) and social engineering techniques (e.g. phishing) are
some examples becoming prevalent. While we often times hear of the more widely publicized
embezzlement, money laundering, burglary and bribery statistics, data has shown that companies
have seen greater losses from losses attributed to information security breaches.
One of the most effective ways to prevent criminals from accessing and compromising
confidential company information is to implement an effective information security plan and
properly train firm employees accessing the system. Additionally, companies should implement
a dynamic and independent third party auditor to frequently test the adequacy of their security
system. Lastly, key responsibilities within the information security chain should be segregated
and rotated frequently. If companies follow these three basic tenets, they will be one step closer
to the effective security of their information.
Threats to Information Systems:
Information security threats come in many different forms. Some of the most common threats
today are software attacks, theft of intellectual property, identity theft, theft of equipment or
information, sabotage, and information infiltration Some of the most prevalent types of data
infiltration include input manipulation, program manipulation, data input manipulation, data
stealing, and outright sabotage. The most frequent type associated with this form of fraud is
manipulation of the data. The reason for this most common is because the criminal requires the
less amount of skill.
Most people have experienced software attacks of some sort. Viruses, worms, phishing
attacks, and Trojan horses are a few common examples of software attacks. Governments,
military, corporations, financial institutions, hospitals and private businesses amass a great deal
of confidential information about their employees, customers, products, research and financial
status. Most of this information is now collected, processed and stored on electronic computers
and transmitted across networks to other computers.
Implementing a Information Security System:
With so many different ways and so much potential for breaches to information security

Solution
Answer is (d).
Independent variable is the teaching method
Dependent variable is the social skills that are learned.
Explanation:
Since, the social skills learned are always dependent on the training method used on the autistic
child. But since we are comparing training methods and also the question has very limited
information about the autistic children, so, training method is independent variable..

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.
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.

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.
