In number of government and private case studies include that the insiders are threat to the organizations as they knowingly participate in cyberattacks have broad range of motivations , financial gain ,revenge , desire for recognition and power response to blackmail , loyality to others in the organizations .organizations must balance the need to access the information for conducting business with protecting this information from unauthorised access and to the secret information is considered as an external threat and it is also malicious threat to organization and that comes from people within the organization such as employees , former employees , contractors and bussiness associates . there are types of insider threats as threats occur for various reasons in some cases individuals use their access to sensitive information for personal or financial gain and they join the third parties such as other organizations or hacking groups and operate on their behalf to gain access from within the network of trust and share a sensitive information and another type of insider threat is referred to as logic bomb and in this harmful software is left running on computer systems by former employe and which cause the problems to complete disaster . insider threats can be intentional or unintentional and this term can be referred to individual who gain insider access using false information but who is not a true employee or an officer of the organization . Insider threats are very difficult to detect , identify and block the outside attacks consider a former employee using an unauthorized login and it wont raise the same security flag as an outsider attempts to gain the access to company secret information or compny network and for this reason insider threats are not detected before access is granted or damage is done . there are many more factors that make insider threats more difficult to detect as for one many individuals with authorized access are also aware of certain security measures which they must find a way to avoid detection and insider threats dont have to get around firewalls or other network based security measures as they work within the network and finally many organizations simply lack the visibility into users access and data activity ie required to sufficiently detect and defend against the insider threats and these are not only present in bussiness organizations but these threats are present in mordern security program so this is the reason why insiders are considered as threat to the organizations. Solution In number of government and private case studies include that the insiders are threat to the organizations as they knowingly participate in cyberattacks have broad range of motivations , financial gain ,revenge , desire for recognition and power response to blackmail , loyality to others in the organizations .organizations must balance the need to access the information for conducting business with protecting this information from u.

Identity Security.docx
Identity Security
Identity security, also known as identity and access management (IAM), refers to a set of practices and technologies used to protect an individual's or organization's digital identity from unauthorized access, theft, or misuse.
Identity security involves managing user access to systems and data, including authentication (verifying the identity of a user), authorization (determining what actions a user is allowed to perform), and accounting (tracking user activity).
Some common identity security practices include strong password policies, multi-factor authentication, access control policies, and regular monitoring and auditing of user activity.
Ensuring strong identity security is crucial in today's digital world, where cyber threats such as identity theft, phishing, and hacking are becoming increasingly prevalent. A breach in identity security can result in financial losses, reputational damage, and legal liabilities for individuals and organizations.
What is Identity Security?
A complete solution for protecting all identities used in an organisation is identity security. It makes the assumption that any identity, including IT administrators, remote workers, third-party vendors, devices, and applications, has the potential to gain privileges under specific circumstances, opening up a door for attackers to access a company's most precious properties. Because of this, an Identity Security method that's also based on privileged control access safeguards all personas or machine—during the process of gaining the necessary resources.
A thorough method to identity security involves precisely authentification each identity, authorising also every identity with the proper authorization, and giving access for that identity to born into privilege assets in a structured way — in an organized way that can be evaluated (or accounted for) to guarantee that the whole process is sound. Organizations should be able to safeguard access across any device, anytime, and at the perfect moment thanks to identity security so they won't have to pick between security and performance.
Why is Identity Security Important?
Identity theft attacks have long been seen as an important channel for organisations to safeguard. The number and variety of identities being used, though, having substantially expanded as a result of current developments over the last several years. For instance, businesses have quickly embraced cloud-based services and technology to improve their competitiveness and provide their clients with engaging digital experiences. As well, they have seen an increase in assistance for dispersed and virtual workforces. All of these trends saw a sharp increase in speed in 2020, a year in which only businesses with robust digital businesses saw success. Attackers are simultaneously developing new strategies and refining old ones, that has given rise to new and enlarged danger landscape aspects.
Identity security is important for several reasons:
1.
Information security threats
What is Information Security?
Information security means that the confidentiality, integrity and availability of information assets is maintained.
Confidentiality: This means that information is only used by people who are authorized to access it.
Integrity: It ensures that information remains intact and unaltered. Any changes to the information through malicious action, natural disaster, or even a simple innocent mistake are tracked.
Availability: This means that the information is accessible when authorized users need it.
Information Security Threats:
Most common types of information security threats are:
Theft of confidential information by hacking
System sabotage by hackers
Phishing and other social engineering attacks
Virus, spyware and malware
Social Media-the fraud threat
Theft of Confidential Information:
One of the major threat to information security is the theft of confidential data by hacking. This includes theft of employee information or theft of trade secrets and other intellectual property (IP).
Theft of Employee Information
Employee information includes credit card information, corporate credit card information, social security number , address, etc. It also includes theft of healthcare records as they contain personal information such date of birth, address, and name of relatives.
Theft of Trade Secrets and other Intellectual Property (IP)
Technology from various verticals including IT, aerospace, and telecommunications are constantly stolen by outsiders or insiders (industrial espionage). China is a growing offender as it continues to advance in technology relying on theft of international trade secrets and IP.
Piracy/copyright infringement.
Corporate business strategies including marketing strategies, product introduction strategies.
System Sabotage:
What is system sabotage?
Planting malware on networks of target organization and generating an enormous amount of transaction activity resulting in malfunction or crash of the system.
Who would perpetrate it?
System sabotage is usually committed by disgruntled ex-employees and by remote cyber-attackers for no particular reason.
The most sensational case of system sabotage: One of the recent examples is the sabotage of Sony PlayStation.
Phishing:
To obtain confidential data about individuals-customers, clients, employees or vendors that can be used to commit various types of identity fraud such as:
Opening bank accounts in victim’s name
Applying for loans in victim’s name
Applying for credit cards in victim’s name
Obtaining medical services in victims name (e-death)
Other kind of more sophisticated social engineering attacks include spear-phishing.
Spear-phishing targets specific individuals such as AP manger, controller, senior accountant to gain access to corporate bank accounts and transfer funds abroad.
Other threats include:
Smishing: Phishing via SMS (texting)
Vishing: Phishing via voice (phone)
Mobile hackin

Re: Doubling Sales
A goal of doubling our sales has been established by my executive management team. This is a newly created, bold, and audacious goal made possible by a win-win relationship with a white knight in the form of a venture capital firm. Retaining and hiring high quality human capital will be made possible by this new investment. Adoption of new leading edge technology and increased capacity will also be made possible by this infusion of new investment. Our company’s executive management team sees an exciting future for the organization.
Our goal can only be met with your help and that of the other middle managers of the company. We want you to empower your people, create synergy by re-organizing your department, and establish operational goals that can be measured, reported, and continuously improved.
The latent talents of our employees, we believe, are a source of untapped sustainable competitive advantage for the company. Reaching our goal of doubling sales is reliant on successfully engaging employees; our management team feels strongly about that. These efforts stand to be derailed by employee dissatisfaction if we do not do something about it right away. The sources of dissatisfaction must be found and fixed with the help of our human resources department. Accomplishing this objective is believed to be one of your highest priorities.
My executive management team and I believe that to efficiently manage your departments’ limited resources you must effectively plan, organize, lead, and control your department. Mistakes were made in the past. Taking the goals given to you by your vice president, breaking them down to supporting activities, communicating them to your staff, and measuring the results is the way for you to be a successful manager.
Good luck with your plans; we are counting on you.

The benefits of implementing access controls for Ben's office
Implementing access control systems will be an asset because of their customizability. You can allow some employees unlimited access, and others access at certain times. Your daytime employees might be granted access between 8-6, while your night staff might have different access. You can go for a keyless system using key codes, fingerprints or facial recognition. With a key card is a good option they can because it can be duplicated. Keeping track of who comes and goes will not only help you be aware of who is inside your building, but will provide a detailed record in the event that there is an issue. A great feature of access control systems is their ability to be controlled remotely. Let’s say someone wants to get inside a room or building and you do not want them to have the code you can let them in remotely. To cut down on cost You can program your access control system to turn of.

Internal Threats and Countermeasures
Cyber-attacks offer the ability to obliterate and interrupt an organization’s communication channels, security data center and facility remotely. Indeed, private and public organizations are often interlinked; hence, data breaches effect damaging impact on the organization’s confidence in protecting the economy and innocent citizens. Today, there is a crisis about organizations’ inability to resolve the age-old problem of how to control the abuse of trust and confidence given to authorized officials to freely logon onto the organization’s system, Many such officials , turn around to betray the organization by committing cybercrimes.
Vulnerability stems from interactions and communications among several system components and categorized as deficiency, weakness and security cavity on network data center.
To what extent do internal threats constitute a key factor against any organization’s ability to battle insider threats caused by people who abuse assigned privilege?
What is the most effective mechanism for organizations to combat internal threats?
Why should disgruntled employees must be trained on the danger of throwing wastepaper and electronic media in a bin within and outside the facility?
Internal threats and countermeasures are isolated occurrences where most activities involve direct connection to the Internet for global interaction, digital communication and transmission. The preeminent method to mitigate internal threats is to equip users with ready-to-act traditional approach. As a result of the sophistication of our modern-day culprits, over-all reliance on employees, increasing credo that authorized users are predictable agent in the fight against internal threats. Internal threat operators often use psychological moralities and procedures to navigate or circumvent security restrictions through persuasion and psychosomatic principles. Criminals use crafty manipulation techniques to sway users into divulging confidential information, such as, usernames, passwords, bank information, house and office alarm codes to take control over organizations’ security centers. Historic channel to internal threats and countermeasures are categorized into employee’s theft, pilferage, embezzlement, fraud, stealing, peculation and defalcation. Most organizations often ignore to establish and adopt on-board ecological waste management action plans to deal with discarded materials, shredded left-over documents, magnetic media and placing fragments in isolated location as countermeasure process.

Length: 1500 words (+/-100)
Introduction
When we consider every modern business, we find that none lacks security issues. This means that we need to look into how to come up with secure systems. Information security stands for prevention or the practice of preventing access of data by unauthorized user. The information does not need to be electrical for it to be secured, even physical information is put into consideration. The purpose of writing this paper is to talk about Fugle Company by describing its information system, outlining the main risks that the system might be exposed to and the ethical issues that need to be considered in order to maintain the security of information in Fugle, (Trend Micro, 2015). For this company to succeed, information security has to be up tight. This technological company has developed an application that you can pay using your fingerprint. A lot of attention has been drawn to it which has risen questions of how secure the application is, (Dooley, 2017). With the scheduled time for launching the application, the company experiences a lot of pressure because they do not want to launch it before considering all the security issues with their budget, and at the same time they do not have a lot of time. The security issues addressed here apply to the HRM, product development, accounting, and marketing information systems.
Information Systems and their Assets
There are four main key information systems in Fugle. When dealing with an information system, we basically mean the software that a company used to analyze and organize its data. It is used to convert raw data into information that can be understood and be used for effective decision making. There are key assets that each one of the four keys have been assigned to protect. We can define an asset as something that is useful for the company that brings profit to it. It is very important to know how to handle threats that are imposed to these assets because they can have a major impact on the future of the company and its viability. In fugle, the main responsibility of the market information system is to make sure that information in the company concerning marketing is not breached. The company’s major assets are its customer Intel and information concerning the asset. This is seen by when Dave is called and is told that there was an attempt of people hacking the data concerning the clients of the company, ( Lowry, Dinev, and Willison, 2017). This would mean that there is a confidentiality breach and the clients would not trust the company again. Also when journalists come to take a look at the product and they are given a controlled presentation it is because the product is still considered vulnerable to attacks. Information about the .

Internal Threats: The New Sources of Attack
In the modern-day climate, more and more industries have had to increase IT security
expenses to provide a trusted system of security to all client/company PII from unauthorized users. The massive spike in IT security spending was brought on by the recent cyber breach on Equifax, in which millions of clients’ PII was accessed and distributed by an unauthorized user infiltrating the system. Like the Equifax attack, so many of these attacks require user-interaction to be activated or spread, so organizations must be on the forefront of understanding the internal threats of their own employees can impose.

(1) What is the purpose of a VLAN trunk?
Ans) A trunk is a line or link designed to handle many signals simultaneously, and that connects
major switching centers or nodes in communication system. The transmitted data can be voice(as
in the conventinal telephone system) data, computer programs, images, video or control signals.
Trunks are used to interconnect switches to form nerwors, and to interconnect local area
nerworks(LAN) to form wide area networks (WAN) or virtual LAN (VLANs). A trunk often
consists of multiple wires, cables, or fiber opric strands to maximize the available bandwidth and
the number of channels that can be accommodated. A trunk can also be a broadband wireless
link. The use and management of trunks in a communications system is known as trunking. It
minimizes the number of physical signal paths, and thus the total amount of cable hardware,
required to serve a given number of suscribers in a nerwork.
In Cisco networks, trunking is special function can be assigned to a port, making thar port
capable of carrying traffic for any or all of the VLANs accessible by particular switch. such a
port is called a trunk port, in contrast to an access port, which carries traffic only to and from the
specific VLAN assigned to it. A trunk port marks frames with special identifying tags (either ISL
tags or 802.1Q tags) as they pass between switches, so easch frame can be routed to its intended
VLAN. An access port does nor provide such tags, because the VLAN for it is pre-assigned, and
identiying markers are therefore unnecessary.
Trunking:-
1)VLANs are local to each swithc\'s database, and VLAN infromation is not passed between
switches.
2)Trunk linksprovies VLAN identification for frames travelling between switches.
3)Cisco seitches have two Ethernet trunking mechanisms: ISL and IEEE 802.1Q
4)certain types of switches can negotiate trunk links.
5)Trunks carry trafic from all VLANs to and from the switch by default but can be configured to
carry only specified VLAN traffic.
6)Trunk links must be configured to allow trunking on each end of the link
2)Will a router always choose a static route over an OSPF route?
Ans) OSPF is an interior gatway routing protocaol that uses link states rather than distance
vectors for path selecation. OSPF propagates link-state advertisments rather than table updates.
Because only LSAs are exchnged, rather than entire routing table, OSPF nerwork converge more
quickly than RIP nerworks. OSPF supports MD5 and clear text neighbor authentication.
Authentiction should be used with all routing protocols when possible because route
redistribution between OSPF and other protocols when possible because route redistribution
between OSPF and other protocols (like RIP) can potentially be used by attackers to subvert
routing information. If NAT is used, if OSPF is operating on public and private areas, and if
address filtering is required, then you need to run two OSPF processes—one process for the
public areas and one .

Keeping track of who comes and goes will not only help you be aware of who is inside your building, but will provide a detailed record in the event that there is an issue. A great feature of access control systems is their ability to be controlled remotely. Let’s say someone wants to get inside a room or building and you do not want them to have the code you can let them in remotely. To cut down on cost You can program your access control system to turn of.

Internal Threats and Countermeasures
Cyber-attacks offer the ability to obliterate and interrupt an organization’s communication channels, security data center and facility remotely. Indeed, private and public organizations are often interlinked; hence, data breaches effect damaging impact on the organization’s confidence in protecting the economy and innocent citizens. Today, there is a crisis about organizations’ inability to resolve the age-old problem of how to control the abuse of trust and confidence given to authorized officials to freely logon onto the organization’s system, Many such officials , turn around to betray the organization by committing cybercrimes.
Vulnerability stems from interactions and communications among several system components and categorized as deficiency, weakness and security cavity on network data center.
To what extent do internal threats constitute a key factor against any organization’s ability to battle insider threats caused by people who abuse assigned privilege?
What is the most effective mechanism for organizations to combat internal threats?
Why should disgruntled employees must be trained on the danger of throwing wastepaper and electronic media in a bin within and outside the facility?
Internal threats and countermeasures are isolated occurrences where most activities involve direct connection to the Internet for global interaction, digital communication and transmission. The preeminent method to mitigate internal threats is to equip users with ready-to-act traditional approach. As a result of the sophistication of our modern-day culprits, over-all reliance on employees, increasing credo that authorized users are predictable agent in the fight against internal threats. Internal threat operators often use psychological moralities and procedures to navigate or circumvent security restrictions through persuasion and psychosomatic principles. Criminals use crafty manipulation techniques to sway users into divulging confidential information, such as, usernames, passwords, bank information, house and office alarm codes to take control over organizations’ security centers. Historic channel to internal threats and countermeasures are categorized into employee’s theft, pilferage, embezzlement, fraud, stealing, peculation and defalcation. Most organizations often ignore to establish and adopt on-board ecological waste management action plans to deal with discarded materials, shredded left-over documents, magnetic media and placing fragments in isolated location as countermeasure process.

Length: 1500 words (+/-100)
Introduction
When we consider every modern business, we find that none lacks security issues. This means that we need to look into how to come up with secure systems. Information security stands for prevention or the practice of preventing access of data by unauthorized user. The information does not need to be electrical for it to be secured, even physical information is put into consideration. The purpose of writing this paper is to talk about Fugle Company by describing its information system, outlining the main risks that the system might be exposed to and the ethical issues that need to be considered in order to maintain the security of information in Fugle, (Trend Micro, 2015). For this company to succeed, information security has to be up tight. This technological company has developed an application that you can pay using your fingerprint. A lot of attention has been drawn to it which has risen questions of how secure the application is, (Dooley, 2017). With the scheduled time for launching the application, the company experiences a lot of pressure because they do not want to launch it before considering all the security issues with their budget, and at the same time they do not have a lot of time. The security issues addressed here apply to the HRM, product development, accounting, and marketing information systems.
Information Systems and their Assets
There are four main key information systems in Fugle. When dealing with an information system, we basically mean the software that a company used to analyze and organize its data. It is used to convert raw data into information that can be understood and be used for effective decision making. There are key assets that each one of the four keys have been assigned to protect. We can define an asset as something that is useful for the company that brings profit to it. It is very important to know how to handle threats that are imposed to these assets because they can have a major impact on the future of the company and its viability. In fugle, the main responsibility of the market information system is to make sure that information in the company concerning marketing is not breached. The company’s major assets are its customer Intel and information concerning the asset. This is seen by when Dave is called and is told that there was an attempt of people hacking the data concerning the clients of the company, ( Lowry, Dinev, and Willison, 2017). This would mean that there is a confidentiality breach and the clients would not trust the company again. Also when journalists come to take a look at the product and they are given a controlled presentation it is because the product is still considered vulnerable to attacks. Information about the .

Internal Threats: The New Sources of Attack
In the modern-day climate, more and more industries have had to increase IT security
expenses to provide a trusted system of security to all client/company PII from unauthorized users. The massive spike in IT security spending was brought on by the recent cyber breach on Equifax, in which millions of clients’ PII was accessed and distributed by an unauthorized user infiltrating the system. Like the Equifax attack, so many of these attacks require user-interaction to be activated or spread, so organizations must be on the forefront of understanding the internal threats of their own employees can impose.

(1) What is the purpose of a VLAN trunkAns) A trunk is a line or .pdf
(1) What is the purpose of a VLAN trunk?
Ans) A trunk is a line or link designed to handle many signals simultaneously, and that connects
major switching centers or nodes in communication system. The transmitted data can be voice(as
in the conventinal telephone system) data, computer programs, images, video or control signals.
Trunks are used to interconnect switches to form nerwors, and to interconnect local area
nerworks(LAN) to form wide area networks (WAN) or virtual LAN (VLANs). A trunk often
consists of multiple wires, cables, or fiber opric strands to maximize the available bandwidth and
the number of channels that can be accommodated. A trunk can also be a broadband wireless
link. The use and management of trunks in a communications system is known as trunking. It
minimizes the number of physical signal paths, and thus the total amount of cable hardware,
required to serve a given number of suscribers in a nerwork.
In Cisco networks, trunking is special function can be assigned to a port, making thar port
capable of carrying traffic for any or all of the VLANs accessible by particular switch. such a
port is called a trunk port, in contrast to an access port, which carries traffic only to and from the
specific VLAN assigned to it. A trunk port marks frames with special identifying tags (either ISL
tags or 802.1Q tags) as they pass between switches, so easch frame can be routed to its intended
VLAN. An access port does nor provide such tags, because the VLAN for it is pre-assigned, and
identiying markers are therefore unnecessary.
Trunking:-
1)VLANs are local to each swithc\'s database, and VLAN infromation is not passed between
switches.
2)Trunk linksprovies VLAN identification for frames travelling between switches.
3)Cisco seitches have two Ethernet trunking mechanisms: ISL and IEEE 802.1Q
4)certain types of switches can negotiate trunk links.
5)Trunks carry trafic from all VLANs to and from the switch by default but can be configured to
carry only specified VLAN traffic.
6)Trunk links must be configured to allow trunking on each end of the link
2)Will a router always choose a static route over an OSPF route?
Ans) OSPF is an interior gatway routing protocaol that uses link states rather than distance
vectors for path selecation. OSPF propagates link-state advertisments rather than table updates.
Because only LSAs are exchnged, rather than entire routing table, OSPF nerwork converge more
quickly than RIP nerworks. OSPF supports MD5 and clear text neighbor authentication.
Authentiction should be used with all routing protocols when possible because route
redistribution between OSPF and other protocols when possible because route redistribution
between OSPF and other protocols (like RIP) can potentially be used by attackers to subvert
routing information. If NAT is used, if OSPF is operating on public and private areas, and if
address filtering is required, then you need to run two OSPF processes—one process for the
public areas and one .

What is Fluorescence Electrons in an atom or a m.pdf
What is Fluorescence? Electrons in an atom or a molecule can absorb the energy in
the electromagnetic radiation and thereby excite to an upper energy state. This upper energy state
is unstable; therefore, electron likes to come back to the ground state. When coming back, it
emits the absorbed wavelength. In this relaxation process, they emit excess energy as photons.
This relaxation process is known as fluorescence. Fluorescence takes place much more rapidly.
Generally, it completes in about 10-5 s or less time from the time of excitation. In atomic
fluorescence, gaseous atoms fluoresce when they are exposed to radiation with a wavelength that
exactly matches one of the absorption lines of the element. For example, gaseous sodium atoms
absorb and excite by absorbing 589 nm radiations. Relaxation takes place after this by
reemission of fluorescent radiation of the identical wavelength. Because of this, we can use
fluorescence to identify different elements. When excitation and reemission wavelengths are the
same, the resulting emission is called resonance fluorescence. Other than fluorescence, there are
other mechanisms by which an excited atom or molecule can give up its excess energy and relax
to its ground state. Nonradiative relaxation and fluorescence emissions are two such important
mechanisms. Because of many mechanisms, the lifetime of an excited state is brief. The relative
number of molecules that fluoresce is small because fluorescence requires structural features that
slow the rate of the nonradiative relaxation and enhance the rate of fluorescence. In most
molecules, these features are not there; therefore, they undergo nonradiative relaxation, and
fluorescence does not occur. Molecular fluorescence bands are made up of a large number of
closely spaced lines; therefore, usually it is hard to resolve. What is Phosphorescence? When
molecules absorb light and go to the excited state they have two options. They can either release
energy and come back to the ground state immediately or undergo other non-radiative processes.
If the excited molecule undergoes a non radiative process, it emits some energy and come to a
triplet state where the energy is somewhat lesser than the energy of the exited state, but it is
higher than the ground state energy. Molecules can stay a bit longer in this less energy triplet
state. This state is known as the metastable state. Then metastable state (triplet state) can slowly
decay by emitting photons, and come back to the ground state (singlet state). When this happens
it is known as phosphorescence. What is the difference between Fluorescence and
Phosphorescence? • When light is supplied to a sample of molecules, we immediately see the
fluorescence. Fluorescence stops as soon as we take away the light source. But phosphorescence
tends to stay little longer even after the irradiating light source is removed. • Fluorescence takes
place when excited energy is released, and the molecule comes back to the gro.

In mathematics, if G is a group, and H is a subgr.pdf
In mathematics, if G is a group, and H is a subgroup of G, and g is an element of G,
then gH = {gh : h an element of H?} is a left coset of H in G, and Hg = {hg : h an element of H?}
is a right coset of H in G. Only when H is normal will the right and left cosets of H coincide,
which is one definition of normality of a subgroup. A coset is a left or right coset of some
subgroup in G. Since Hg = g?(?g-1Hg?), the right cosets Hg (of H?) and the left cosets g?(?g-
1Hg?) (of the conjugate subgroup g-1Hg?) are the same. Hence it is not meaningful to speak of a
coset as being left or right unless one first specifies the underlying subgroup. In other words: a
right coset of one subgroup equals a left coset of a different (conjugate) subgroup. If the left
cosets and right cosets are the same then H is a normal subgroup and the cosets form a group
called the quotient group. The map gH?(gH)-1=Hg-1 defines a bijection between the left cosets
and the right cosets of H, so the number of left cosets is equal to the number of right cosets. The
common value is called the index of H in G. For abelian groups, left cosets and right cosets are
always the same. If the group operation is written additively then the notation used changes to
g+H or H+g. Cosets are a basic tool in the study of groups; for example they play a central role
in Lagrange\'s theorem. Examples et G be the multiplicative group of {-1,1}, and H the trivial
subgroup (1,*). Then -1H={-1}, 1H=H are the sole cosets of H in G. Let G be the additive group
of integers Z = {..., -2, -1, 0, 1, 2, ...} and H the subgroup mZ = {..., -2m, -m, 0, m, 2m, ...}
where m is a positive integer. Then the cosets of H in G are the m sets mZ, mZ+1, ... mZ+(m-1),
where mZ+a={..., -2m+a, -m+a, a, m+a, 2m+a, ...}. There are no more than m cosets, because
mZ+m=m(Z+1)=mZ. The coset mZ+a is the congruence class of a modulo m.[1] Another
example of a coset comes from the theory of vector spaces. The elements (vectors) of a vector
space form an abelian group under vector addition. It is not hard to show that subspaces of a
vector space are subgroups of this group. For a vector space V, a subspace W, and a fixed vector
a in V, the sets are called affine subspaces, and are cosets (both left and right, since the group is
abelian). In terms of geometric vectors, these affine subspaces are all the \"lines\" or \"planes\"
parallel to the subspace, which is a line or plane going through the origin
Solution
In mathematics, if G is a group, and H is a subgroup of G, and g is an element of G,
then gH = {gh : h an element of H?} is a left coset of H in G, and Hg = {hg : h an element of H?}
is a right coset of H in G. Only when H is normal will the right and left cosets of H coincide,
which is one definition of normality of a subgroup. A coset is a left or right coset of some
subgroup in G. Since Hg = g?(?g-1Hg?), the right cosets Hg (of H?) and the left cosets g?(?g-
1Hg?) (of the conjugate subgroup g-1Hg?) are the same. Hence it is .

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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
