You are asked with writing a program in C that manages contact infor.pdf
You are asked with writing a program in C that manages contact information for a group of
people. The program should save the first name, last name, and telephone number for up to 12
people. The program should have options to add a person, delete a person, update the
information for a person, and display all information for all current entries. How could you go
about breaking up the programming work into a set of subproblems that could be implemented
separately?
Solution
Whenever we asked about these type of problems.we just go to data structures.i.e,Data structures
that are suitable to our problem whether it may be linked lists,arrays,trees.Here we are taking
about a person information that to it is not about a single person information.
1)Identify data structure.Here i think linked list data structure can be used because array cannot
store all information about a person.and arrays cannot support delete operation like that.
2)1st sub problem:creating a structure to a single person
3)2nd sub problem:add a person:inserting data in linked list by creating a single node
3)updating information:modifying node information in single linked list
4)delete the information of a person:delete a single node information in single linked list
5)display all information for all current entries:traversing a single linked list.
each step is considered to subproblem or function in \'C\' language..
Write a short paragraph explaining what the exploit does in Assembly.pdf
Write a short paragraph explaining what the exploit does in Assembly , and how it works. How
could the
programmer of vecho have prevented this from happening?
Solution
Exploit in assembly allows us to gain unauthorized root priviledge by using buffer overflow. It
allows hackers to gain access to addresses beyond the eip register. Exploits are generally used in
developing virus. The command vecho, which is similar to the echo command is vulnerable and
used in exploits.
The programmers of vecho should have checked for the address in the eip register and any
attempt to access addresses beyond it should have thrown an error..

What quality control mechanisms should major accounting firms have i.pdf
What quality control mechanisms should major accounting firms have in place to ensure that
audit partners have the proper training and experience to supervise audit engagements?
Solution
Quality control measures the major Accounting firm have in place in order to ensure that
auditors have proper training and experience to supervise audit engagements are
(1) Integrity, objectivity and independence: The auditor should be straight forward, honest and
sincere in his approach to his professional work. He should maintain an impartial
attitude and both be and appear to be free of any interest which might be regarded, whatever is
actual effect, as being incompatible with integrity and objectivity.
(2) Confidentiality: The auditor should respect the confidentiality of information acquired in the
course of his work and should not disclose any such information to a third party without The
specific authority or unless there is a legal or professional duty to disclose.
(3) Skills and Competence: The audit should be performed and the report prepared with due
professional care by persons who have adequate training, experience and competence in
auditing. The auditor requires specialised skills and competence along with a continuing
awareness of developments including pronouncements of the accounting body on accounting and
auditing matters, and relevant regulations and statutory requirements.
(4) Work performed by others: When the auditor delegates work to assistants or uses work
performed by other auditors and experts, he continues to be responsible for forming and
expressing his opinion on the financial information.
These are the some of the measures to have proper training and experience to supervise audit
engagements
I WOULD LIKE TO SHARE YOU ABOUT LETTER OF ENGAGEMENT IN SHORT
Letter of Engagement: The legal requirement to get the accounts audited so far extends only to
companies, co-operative societies, and registered societies. In these cases, the respective law

What are three basic ethical principles for journalism Why are ethi.pdf
What are three basic ethical principles for journalism? Why are ethics so important for a writer?
Solution
Three major ethical principles are
Truth and Accuracy
Journalists cannot always guarantee ‘truth’, but getting the facts right is the cardinal principle of
journalism. We should always strive for accuracy, give all the relevant facts we have and ensure
that they have been checked. When we cannot corroborate information we should say so.
Independence
Journalists must be independent voices; we should not act, formally or informally, on behalf of
special interests whether political, corporate or cultural. We should declare to our editors – or the
audience – any of our political affiliations, financial arrangements or other personal information
that might constitute a conflict of interest.
Fairness and Impartiality
Most stories have at least two sides. While there is no obligation to present every side in every
piece, stories should be balanced and add context. Objectivity is not always possible, and may
not always be desirable (in the face for example of brutality or inhumanity), but impartial
reporting builds trust and confidence..

What are some of the different versions of UNIX®? Why is it important to have different
versions of UNIX®?
Solution
Versions of UNIX
Many versions of UNIX, including System V Release 4, merge earlier AT&T releases with BSD
features. In last few years ago, there were two main versions:
[1] The line of UNIX releases that started at AT&T (the latest is System V Release 4)
[2] The University of California at Berkeley (the latest version is BSD 4.4).
Some more commercial versions include Solaris, SCO UNIX , SunOS, AIX, HP/UX, and
ULTRIX. The recent POSIX standard for UNIX-like operating systems defines a single interface
to UNIX..

In details, discuss the following questions in three to four pages: 1- Give one of your own
experiences in which your intrinsic motivation changed into extrinsic [LO31| 10 Marks]
motivation as through competition, or rewards. What are some activities you do because you get
external rewards, or because you are avoiding some punishment? 2- LO41[10 Marks]
Solution
Extrinsic motivation refers to behavior that is driven by external rewards such as money, fame,
grades, and praise. This type of motivation arises from outside the individual, as opposed to
intrinsic motivation, which originates inside of the individual.”
? Intrinsic motivation refers to behavior that is driven by internal rewards. In other words, the
motivation to engage in a behavior arises from within the individual because it is intrinsically
rewarding.”
Example of Coversion of intricsic motivation into extrinsic motivation
My personel life experiance is to become CA ....... i want to become CA because i m intrested in
accountancy field from start of 10th class when i solve one problem based on account field very
easily and with intrest taking in solving that problem .... then i decided to take commerce an
choose CA field ..when i came in this field then discussion with the person around me were CA
.....then i knwe All about their struggle and theri popularity after become CA .....that all thing
also motivates us .
We think that is disputable, and in some way, outrageous proposal to withhold reward in school
setting that is based in the studies of motivation involved in Deci\' s and his associates meta-
analysis. From the 70\'s and onwards there was a significant endeavor in the research agendas.
Behavioral model of learning through rigid control of external reward is no longer the dominant
paradigm. Researcher\'s attention has been placed on the contribution of valuable learning that
comes from personal effort and \"inner senses\". Therefore, maybe it is time to move the agenda
to the orientation of the synthesis of external and internal motivation that will engage students,
especially adolescents, within the accepted teaching skills and competencies necessary for
creative and productive future. And we should not forget the fact that in most cases the
researchers were successful in identifying factors that reduce interest than factors that reinforce
them. Only recently, researchers have begun to portray interventions that may enhance the
interest and therefore the value, importance and meaning of the activities or polishing of the
structure of
Activites done for reward.

Linux network interface names start with ethX. First Ethernet network interface name is eth0,
second is eth1,eth2 and so on.
Login as a root user, use su – command:
$ su –
To list or display more information about network interface type command:
# ifconfig | less
To assign an IP address type following command:
# ifconfig eth2 192.168.1.9 up
To take down network interface type following command:
# ifconfig eth2 down
To configure network card using GUI tool type command:
# redhat-config-network
You can also type command setup and select network configuration from menu:
# setup
If you wish to configure network interface eth2 manually then you need to edit files stored in
/etc/sysconfig/network-scripts/ directory. For example here is my sample /etc/sysconfig/network-

QUESTION:
Discuss how has Web 2.0 changed the behavior of Internet users? What are the basic tools or
applications that characterize Web 2.0?
While IT provides the platform for this phenomenon, the changing behavior of users represents
the biggest challenge and opportunity for businesses today. Web 2.0 also represents opportunities
for those who understand and master the new way of doing things. Managers who invest the time
to understand and become proficient in new approaches to identifying, communicating and
building relationships with customers online will have a tremendous advantage over managers
who limit themselves to traditional methods.
Blog is short for “Web Log” and is a Web site where users regularly post information for others
to read. Blogs allow readers to comment on each posting. Blogs are a key tool for organizations
that practice content marketing, where valuable information is shared with current or prospective
customers. Bloggers can establish a lot of credibility for themselves and their organizations by

Solution
I have only corrected the journal entries marked in red
Calculation of cash dividends on Dec1:
No of common stock shares outstanding: (1033,333/4) + 4620 - 4400 - 1250 = 257303.25
<4620 is additional shares issued; 4400 is treasury stock; 1250 is additional treasury stock>
Cash dividend declared = 0.85 per share
Hence, total cash dividend = 257303.25 x 0.85 = $218708
Calculation of cash dividends on Dec 31:

Solution
As per the rule i have answered your first question:
Reoviridae: Reoviridae are currently classified into nine genera. The genomes of these viruses
consist of 10 to 12 segments of dsRNA, each generally encoding one protein. The mature virions
are non-enveloped. Their capsids, formed by multiple proteins, have icosahedral symmetry and
are arranged generally in concentric layers. A distinguishing feature of the dsRNA viruses,
irrespective of their family association, is their ability to carry out transcription of the dsRNA
segments, under appropriate conditions, within the capsid. In all these viruses, the enzymes
required for endogenous transcription are thus part of the virion structure.
Orthoreoviruses: The orthoreoviruses (reoviruses) are the prototypic members of the virus
Reoviridae family and representative of the turreted members, which comprise about half the
genera. Like other members of the family, the reoviruses are non-enveloped and characterized by
concentric capsid shells that encapsidate a segmented dsRNA genome. In particular, reovirus has
eight structural proteins and ten segments of dsRNA. A series of uncoating steps and
conformational changes accom.
In what ways do the experts foresee the use of both virtualization a.pdf
In what ways do the experts foresee the use of both virtualization and cloud computing evolving
in the future?
Solution
Use ofVirtualization and cloud computing security :
• Self-defending VM security
• Layered coordinated defenses
• Security optimized for virtual and cloud environments
• Visibility, reporting, and auditing
• Encryption for virtual and cloud environments
• Security that travels with data
Security solutions should offer both agent-less and agent-based security options to provide
flexible deployment alternatives and close security gaps unique to virtualized and cloud
environments.
Encryption addresses a range of security challenges related to virtualization and cloud
computing. Standard 128-, 192-, or 256-bit encryption of storage volumes deters hackers from
prying and thieving, and reduces the risk that the cloud storage devices could be sold or reused
while they still contain confidential or private information. Encryption also greatly reduces the
risk of malicious VM attacks; as long as the encryption key for the data stores have not been
provided, even if rogue VMs reach data stores, volumes are unmountable and unreadable.
Encryption with enterprise-controlled key management enables IT to comply with security best
practices, internal governance, and external regulation. Data is kept secure, and the key
management solution can provide monitoring, reporting, and auditing capabilities that provide
visibility into data access. As a result, enterprises realize a significant reduction in the scope of
compliance audits.
Encryption for virtual and cloud environments:
In summary, best practices for encryption for virtual and cloud data protection include: •
Integration with leading cloud service providers and virtual environments. • Policy-based key
management that determines where and when encrypted data can be accessed. • Identity-based
and integrity-based server validation to determine which servers can access secure storage
volumes and whether security is up-to-date on those servers prior to data access. • Business
control of encryption keys, either on-site or through a separate SaaS service, to maintain a strict
separation of duties between the business and cloud service provider..
In the Meselson Stahl experiment, E. coli was grown for many generati.pdf
In the Meselson Stahl experiment, E. coli was grown for many generations in a medium
\"heavy\" nitrogen^15 N. Once the bacterial DNA was uniformly labeled, the bacteria were
transferred to a medium containing the \"light\" nitrogen, ^14N. After ONE round of replication,
DNA was extracted and subjected to density gradient centrifugation in cesium chloride. Upon
inspection, there was only a single band of intermediate density DNA in the gradient. This
proved that DNA replication CANNOT be conservative dispersive semiconservative
conservative of dispersive continuous.
Solution
Answer is Dispersive replication.
Dispersive replication would result in double-stranded DNA with both strands having mixtures
of 15N and 14N DNA, either of which would have appeared as DNA of an intermediate density..

behavioral profile roles during team entry and identify how the profiles are demonstrated in the
case. Explain your answer. Was the communication among the participants in the case effective
or not? Justify your answer (this is not just an opinion).
West Coast Transit Company Profile West Coast Transit began as a small, charter airline in
2005. Its initial vision was providing affordable, on-the-hour flights from California-based
airports to its three adjacent states: Arizona, Nevada, and Oregon. West Coast Transit recognized
that the need for affordable and convenient flights out of California was high enough to sustain a
business. The company began its success using smaller commuter planes to transport customers
to surrounding airports. There was no flight longer than 2 hours and there was minimal service
during the flight. The company’s mission was customer-focused, to provide an opportunity for
companies to fly their employees at an affordable rate and whole families to travel affordably.
West Coast Transit tripled in size after its first year. Growing demand required the addition of
flights, employees, and larger airplanes. The founders of the company reevaluated the vision and
future of West Coast Transit. The company were determined to maintain an emphasis on
convenient, affordable flights and keep its focus on customer needs. This strategy proved
successful. The company has established itself as a dominant regional competitor. West Coast
Transit has over 10,000 employees and continues to see growth in its future. Most employees at
West Coast Transit rave about the company and appreciate its friendly and employee-centered
culture. The company’s leadership cares about its employees and makes every effort to provide
them with satisfactory benefits. Most employees are enthusiastic about the impact they make on
customers, their salaries and benefits, and the advancement opportunities the company provides.
They feel valued and respected. One major complaint that a majority of the employees has is the
turnaround demand. Employees are given very little time and support to complete a project.
There is just too much work to be done. Most employees are successful under pressure, but
would appreciate an environment that provides adequate time to complete projects productively.

Explain the differences between PL and PLE measurements; Explain why .pdf
Explain the differences between PL and PLE measurements; Explain why the PLE experiment
can provide information about the absorption features of a semiconductor! Explain why PL
spectrum is typically much narrower than absorption spectrum; Explain why we say optical
transitions are \"vertical\".
Solution
the PL measurements are based on fixed energy excitation.and detection energy is varied.PLE is
just reverse process we have detection energy fixed and excitation energy varied.
PLE spectroscopy is a useful method to investigate the electronic level structure of materials
with low absorption due to the superior signal-to-noise ratio of the method compared to
absorption measurements.
PL spectroscopy is a contactless, nondestructive method of probing the electronic structure of
materials. Light is directed onto a sample, where it is absorbed and imparts excess energy into
the material in a process calledphoto-excitation. One way this excess energy can be dissipated by
the sample is through the emission of light, orluminescence. In the case of photo-excitation, this
luminescence is calledphotoluminescence or PL.
As fluorophores play the central role in fluorescence spectroscopy and imaging we will start with
an investigation of their manifold interactions with light. Afluorophore is a component that
causes a molecule to absorb energy of a specific wavelength and then re-remit energy at a
different but equally specific wavelength. The amount and wavelength of the emitted energy
depend on both the fluorophore and the chemical environment of the fluorophore. Fluorophores
are also denoted as chromophores, historically speaking the part or moiety of a molecule
responsible for its color. In addition, the denotation chromophore implies that the molecule
absorbs light while fluorophore means that the molecule, likewise,emits light. The umbrella term
used in light emission is luminescence, whereas fluorescence denotes allowed transitions with a
lifetime in the nanosecond range from higher to lower excited singlet states of molecule.thats
why narrower..

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”.
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.

Solution
Linux network interface names start with ethX. First Ethernet network interface name is eth0,
second is eth1,eth2 and so on.
Login as a root user, use su – command:
$ su –
To list or display more information about network interface type command:
# ifconfig | less
To assign an IP address type following command:
# ifconfig eth2 192.168.1.9 up
To take down network interface type following command:
# ifconfig eth2 down
To configure network card using GUI tool type command:
# redhat-config-network
You can also type command setup and select network configuration from menu:
# setup
If you wish to configure network interface eth2 manually then you need to edit files stored in
/etc/sysconfig/network-scripts/ directory. For example here is my sample /etc/sysconfig/network-
scripts/ifcfg-eth2 file for eth2 network interface:
DEVICE=eth2
BOOTPROTO=static
BROADCAST=192.168.1.255
HWADDR=00:0F:EA:91:04:07
IPADDR=192.168.1.9
NETMASK=255.255.255.0
NETWORK=192.168.1.1
ONBOOT=yes

Solution
I have only corrected the journal entries marked in red
Calculation of cash dividends on Dec1:
No of common stock shares outstanding: (1033,333/4) + 4620 - 4400 - 1250 = 257303.25
<4620 is additional shares issued; 4400 is treasury stock; 1250 is additional treasury stock>
Cash dividend declared = 0.85 per share
Hence, total cash dividend = 257303.25 x 0.85 = $218708
Calculation of cash dividends on Dec 31:

Solution
As per the rule i have answered your first question:
Reoviridae: Reoviridae are currently classified into nine genera. The genomes of these viruses
consist of 10 to 12 segments of dsRNA, each generally encoding one protein. The mature virions
are non-enveloped. Their capsids, formed by multiple proteins, have icosahedral symmetry and
are arranged generally in concentric layers. A distinguishing feature of the dsRNA viruses,
irrespective of their family association, is their ability to carry out transcription of the dsRNA
segments, under appropriate conditions, within the capsid. In all these viruses, the enzymes
required for endogenous transcription are thus part of the virion structure.
Orthoreoviruses: The orthoreoviruses (reoviruses) are the prototypic members of the virus
Reoviridae family and representative of the turreted members, which comprise about half the
genera. Like other members of the family, the reoviruses are non-enveloped and characterized by
concentric capsid shells that encapsidate a segmented dsRNA genome. In particular, reovirus has
eight structural proteins and ten segments of dsRNA. A series of uncoating steps and
conformational changes accom.
In what ways do the experts foresee the use of both virtualization a.pdf
In what ways do the experts foresee the use of both virtualization and cloud computing evolving
in the future?
Solution
Use ofVirtualization and cloud computing security :
• Self-defending VM security
• Layered coordinated defenses
• Security optimized for virtual and cloud environments
• Visibility, reporting, and auditing
• Encryption for virtual and cloud environments
• Security that travels with data
Security solutions should offer both agent-less and agent-based security options to provide
flexible deployment alternatives and close security gaps unique to virtualized and cloud
environments.
Encryption addresses a range of security challenges related to virtualization and cloud
computing. Standard 128-, 192-, or 256-bit encryption of storage volumes deters hackers from
prying and thieving, and reduces the risk that the cloud storage devices could be sold or reused
while they still contain confidential or private information. Encryption also greatly reduces the
risk of malicious VM attacks; as long as the encryption key for the data stores have not been
provided, even if rogue VMs reach data stores, volumes are unmountable and unreadable.
Encryption with enterprise-controlled key management enables IT to comply with security best
practices, internal governance, and external regulation. Data is kept secure, and the key
management solution can provide monitoring, reporting, and auditing capabilities that provide
visibility into data access. As a result, enterprises realize a significant reduction in the scope of
compliance audits.
Encryption for virtual and cloud environments:
In summary, best practices for encryption for virtual and cloud data protection include: •
Integration with leading cloud service providers and virtual environments. • Policy-based key
management that determines where and when encrypted data can be accessed. • Identity-based
and integrity-based server validation to determine which servers can access secure storage
volumes and whether security is up-to-date on those servers prior to data access. • Business
control of encryption keys, either on-site or through a separate SaaS service, to maintain a strict
separation of duties between the business and cloud service provider..
In the Meselson Stahl experiment, E. coli was grown for many generati.pdf
In the Meselson Stahl experiment, E. coli was grown for many generations in a medium
\"heavy\" nitrogen^15 N. Once the bacterial DNA was uniformly labeled, the bacteria were
transferred to a medium containing the \"light\" nitrogen, ^14N. After ONE round of replication,
DNA was extracted and subjected to density gradient centrifugation in cesium chloride. Upon
inspection, there was only a single band of intermediate density DNA in the gradient. This
proved that DNA replication CANNOT be conservative dispersive semiconservative
conservative of dispersive continuous.
Solution
Answer is Dispersive replication.
Dispersive replication would result in double-stranded DNA with both strands having mixtures
of 15N and 14N DNA, either of which would have appeared as DNA of an intermediate density..

Write a paper (1,000) in which you address the following based on the information provided in
the \"West Coast Transit Case Study\" resource. Define the three criteria for evaluating effective
team/group work and analyze whether the \"team\" assembled by Bernie Hollis and Pete Denson
is effective or not. Provide a review of each of Tuckman\'s five stages of group formation and
identify what stage(s) are evident in the case. Explain your answer. Define Schein’s three
behavioral profile roles during team entry and identify how the profiles are demonstrated in the
case. Explain your answer. Was the communication among the participants in the case effective
or not? Justify your answer (this is not just an opinion).
West Coast Transit Company Profile West Coast Transit began as a small, charter airline in
2005. Its initial vision was providing affordable, on-the-hour flights from California-based
airports to its three adjacent states: Arizona, Nevada, and Oregon. West Coast Transit recognized
that the need for affordable and convenient flights out of California was high enough to sustain a
business. The company began its success using smaller commuter planes to transport customers
to surrounding airports. There was no flight longer than 2 hours and there was minimal service
during the flight. The company’s mission was customer-focused, to provide an opportunity for
companies to fly their employees at an affordable rate and whole families to travel affordably.
West Coast Transit tripled in size after its first year. Growing demand required the addition of
flights, employees, and larger airplanes. The founders of the company reevaluated the vision and
future of West Coast Transit. The company were determined to maintain an emphasis on
convenient, affordable flights and keep its focus on customer needs. This strategy proved
successful. The company has established itself as a dominant regional competitor. West Coast
Transit has over 10,000 employees and continues to see growth in its future. Most employees at
West Coast Transit rave about the company and appreciate its friendly and employee-centered
culture. The company’s leadership cares about its employees and makes every effort to provide
them with satisfactory benefits. Most employees are enthusiastic about the impact they make on
customers, their salaries and benefits, and the advancement opportunities the company provides.
They feel valued and respected. One major complaint that a majority of the employees has is the
turnaround demand. Employees are given very little time and support to complete a project.
There is just too much work to be done. Most employees are successful under pressure, but
would appreciate an environment that provides adequate time to complete projects productively.

been handed a last-minute project to lead a team consisting of .

Explain the differences between PL and PLE measurements; Explain why .pdf
Explain the differences between PL and PLE measurements; Explain why the PLE experiment
can provide information about the absorption features of a semiconductor! Explain why PL
spectrum is typically much narrower than absorption spectrum; Explain why we say optical
transitions are \"vertical\".
Solution
the PL measurements are based on fixed energy excitation.and detection energy is varied.PLE is
just reverse process we have detection energy fixed and excitation energy varied.
PLE spectroscopy is a useful method to investigate the electronic level structure of materials
with low absorption due to the superior signal-to-noise ratio of the method compared to
absorption measurements.
PL spectroscopy is a contactless, nondestructive method of probing the electronic structure of
materials. Light is directed onto a sample, where it is absorbed and imparts excess energy into
the material in a process calledphoto-excitation. One way this excess energy can be dissipated by
the sample is through the emission of light, orluminescence. In the case of photo-excitation, this
luminescence is calledphotoluminescence or PL.
As fluorophores play the central role in fluorescence spectroscopy and imaging we will start with
an investigation of their manifold interactions with light. Afluorophore is a component that
causes a molecule to absorb energy of a specific wavelength and then re-remit energy at a
different but equally specific wavelength. The amount and wavelength of the emitted energy
depend on both the fluorophore and the chemical environment of the fluorophore. Fluorophores
are also denoted as chromophores, historically speaking the part or moiety of a molecule
responsible for its color. In addition, the denotation chromophore implies that the molecule
absorbs light while fluorophore means that the molecule, likewise,emits light. The umbrella term
used in light emission is luminescence, whereas fluorescence denotes allowed transitions with a
lifetime in the nanosecond range from higher to lower excited singlet states of molecule.thats
why narrower..

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”.
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.

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.
