Female copperhead snakes have the ability to reproduce both sexually.pdf
Female copperhead snakes have the ability to reproduce both sexually and asexually. In your
opinion, which method is best for the species in general and why? include the following in your
post:
Discuss asexual and sexual reproduction in terms of genetic diversity. How is meiosis related to
genetic diversity?
Use one of Gregor Mendel\'s ideas to support your opinion.
Solution
Female copperhead snakes have the ability to reproduce both sexually and asexually. While
asexual reproduction involves only one organisms, sexual reproduction requires both a male and
a female.
According to my opinion, the best reproduction method for this species is sexual reproduction.
The reason is that after several years the species would lose its ability to thrive in a given
environment. This ultimately would lead to an extinction of the species after many years, and
would leave this particular species open to other prey because of its ability to survive.
Sexual vs Asexual in terms of genetic diversity and meiosis relationship:
The process of sexual reproduction involves two parents, each contributing one gamete. Gametes
are produced by a process called meiosis, which starts by the duplication of chromosomes,
followed by two rounds of cell divisions and halving of the chromosome number. Gametes have
half the chromosome number of other adult cells of organism. A key feature of meiosis is the
excahnge of chromosome pieces which occurs in the first division of this process, called
recombination or crossing over. Recombination is a very improtant source of genetic variation
between individuals of sexually reproducting species, and the driving force for the process of
nature selection.
Gregor Mendel known as the father of Genetics came up with different ideas or theories relating
to genetics in offspring. His theory that best fits my opinion is the blending theory of inheritance.
The Blending theory of inheritance states, the original parental traits were lost or absorbed by the
blending in the offspring..

Explain some of the commonly held misconceptions about cloning. Why do you think people
have these kinds of misconceptions?
Solution
There remains several misconceptions about cloning , as-
1.cloning can create carbon copy of the original,
2.it is against the nature, as it reduce biological diversity
3.people create clone for selfish reasons,
4.clones will have shorter life span.
5.human clones will be used as organ donors.
the cause of misconcept of people due to lack of knowledge about cloning, and may be we are
afraid of its consequences whih we think go against us, beside that there are also several ethical
issues..
Describe nN when the number of positive divisors of n is i) p2 for .pdf
Describe nN when the number of positive divisors of n is: i) p2 for p a prime; ii) 105.
Solution
There exist an infinite number of primes.
Proof. Suppose that there are a finite number of primes, say p1, p2, . . . , pn. Let N = p1p2 · · · pn
+ 1. By the fundamental theorem of arithmetic, N is divisible by some prime p. This prime p
must be among the pi , since by assumption these are all the primes, but N is seen not to be
divisible by any of the pi , contradiction..
Describe one derived trait in humans (Homo sapiens).SolutionThe.pdf
Describe one derived trait in humans (Homo sapiens).
Solution
The latest chapter of human evolution begins with the emergence of Homo sapiens. The anatomy
of Homo sapiens is unique among hominin species and appears first in East Africa, dating to
roughly 160 thousand years ago. These unique features—including changes in the skull and
postcranial skeleton (skeleton minus skull) - suggest changes in brain size and architecture and
an adaptation to tropical environments. These anatomical changes are linked to cognitive and
behavioral changes that are equally unique among hominin species. In particular, the
archaeological evidence of behaviors thought to be unique to Homo sapiens, which appear first
in Africa around 170 ka, highlight the importance of symbolism, complex cognitive behaviors,
and a broad subsistence strategy (the strategy used to procure food). The evolution of Homo
sapiens is vitally important to defining our species in the broader context of human evolution and
also has key to understanding the human condition, past and present.
Food: All Homo sapiens were once hunter-gatherers living on wild plants and animals. It was
only about 11,000 years ago that humans began to domesticate plants and animals although wild
foods still remained important in the diet. Our species has a wide-ranging and essentially
omnivorous diet. This has enabled us to utilise the food resources found in the wide variety of
environments we inhabit.
Settlement: Early Homo sapiens often inhabited caves or rock shelters if these were available.
More recently, especially within the last 20,000 years, natural shelters were enhanced with walls
or other simple modifications. In open areas, shelters were constructed using a range of
framework materials including wooden poles and the bones of large animals, such as mammoths.
These structures were probably covered with animal hides and the living areas included fire
hearths.
Living sites were much larger than those occupied by earlier humans and a comparison with
modern traditional peoples suggests that clans consisted of between 25 and 100 members.
Other significant morphological changes included: the evolution of a power and precision grip; a
reduced masticatory system; a reduction of the canine tooth; and the descent of the larynx and
hyoid bone, making speech possible. An important physiological change in humans was the
evolution of hidden oestrus, or concealed ovulation, which may have coincided with the
evolution of important behavioural changes, such as pair bonding. Another significant
behavioural change was the development of material culture, with human-made objects
becoming increasingly common and diversified over time. The relationship between all these
changes is the subject of ongoing debate..

Chickens vary in color. Black and white color variation can be traced.pdf
Chickens vary in color. Black and white color variation can be traced to a single co-dominant
gene in which black chickens and white chickens are each homozygous for the black (BB) and
white (bb) allele, respectively, while speckled hens are heterozygous (Bb) Cause of Variation If
one of the alleles was ancestral, what is the most likely event that caused the other allele
encoding a color variant to arise in chickens? During which cellular process did this most event
most likely occur? Name one enzyme that was involved in this cellular process. Selection and
the maintenance of variation Generate a hypothesis for why this variation in chicken color may
be present today (do not consider the hypothetical situation in Q2b) Hypothetically, say that
speckled hens lay twice as many eggs, and thus produce twice as many offspring as either white
or black hens. If this were the case, briefly explain one possible reason that black and white
chickens are still produced.
Solution
Codominance is observed when two different alleles of a specific single-gene trait are both
expressed simultaneously. It follows non-Mendelian inheritance patterns. Both the dominant
alleles coexist and work together to express both phenotypes in equal measures. This would lead
to the phenotype having characteristics of both alleles.
For example, feather colour in hens may be white, black or speckled (it has both white feathers
and black feathers). The alleles can be shown as W for white and B for black.
There are three possible genotypes: WW, BB and BW.
There are also three possible phenotypes: WW = white, BB = black, and BW = speckled.
The event which may have caused the allele ecoding a color varient could be that, When genes
are far apart on the chromosome they can segregate independantly. This is due to crossing over.
this event occurs during meiotic division.Mutations are caused due to this and give rise to
variations.
In birds and mammals, unpigmented pigment cell precursors known as melanoblasts migrate
from the neural crest to the epidermis and into developing feather or hair follicles. Mature
pigment cells known as melanocytes synthesize melanin pigment, package it into melanosomes
and then transfer those melanosomes to keratinocytes for deposition into developing feathers and
hairs.Though mammals and birds have only one pigment cell type, the melanocyte, these cells
can produce either eumelanin (black/brown) or pheomelanin (yellow/red) and can switch rapidly
between the synthesis of these two pigment types
Increased production of eumelanin and a corresponding reduction in pheomelanin synthesis
generates a melanic phenotype, which may be dark brown or entirely black. This switch is
primarily controlled by the interaction of two genes: the melanocortin receptor 1 (Mc1r) and
agouti.
which are affected by mutations and polymorphisms.Melanism is the pattern,Mc1r is the gene
inchicken (Gallus gallus).

In birds and mammals, unpigmented pigment cell precursors known as melanoblasts migrate
from the neural crest to the epidermis and into developing feather or hair follicles. Mature
pigment cells known as melanocytes synthesize melanin pigment, package it into melanosomes
and then transfer those melanosomes to keratinocytes for deposition into developing feathers and
hairs.Though mammals and birds have only one pigment cell type, the melanocyte, these cells
can produce either eumelanin (black/brown) or pheomelanin (yellow/red) and can switch rapidly
between the synthesis of these two pigment types
Increased production of eumelanin and a corresponding reduction in pheomelanin synthesis
generates a melanic phenotype, which may be dark brown or entirely black. This switch is
primarily controlled by the interaction of two genes: the melanocortin receptor 1 (Mc1r) and
agouti.
which are affected by mutations and polymorphisms.Melanism is the pattern,Mc1r is the gene

Problem: Run For Charity (charityrun.c)
Charity Runs are a popular way for organizations to raise awareness and get fit at the same time.
However, these events can be tough to organize. The Princess Half Marathon Weekend, for
example, has as many as 40,000 runners raising money and awareness for the Children’s Miracle
Network Hospitals. People can run both 5ks and 10ks and there’s even a children’s race.
After nearly a semester of C programming, you\'ve decided that you\'d like to donate your skills
to create a program that organizes the typical activities for charity run weekend. In particular,
your program will help manage the following:
1) Individual Registration
2) Team Registration
3) Running Events
4) Donation Totals
Your program will log the number of teams and individual who are signed up for the different
races, process the racing events to see who has the fastest times, and track the total amount of
money raised by teams and individuals for charity.
Header Specification
To facilitate grading, include in your header comment which portions of the assignment you
have completed. You must complete all portions in order to earn full credit, but partial credit is
available for completing some of the steps. The primary steps are as follows:
(1) Processing Individual Registrations
(2) Processing Team Registrations
(3) Processing the running events
(4) Calculating total donations
If your comment is accurate, meaning that you pass the appropriate tests cases corresponding to
your choice, you\'ll earn 10 points. If your comment is roughly accurate, meaning that you
sincerely attempted the items you listed, and most of them work minus a tiny bug, then you\'ll
get 5 of these points. If your comment isn\'t accurate to a reasonable degree, you\'ll get 0 of these
points.
The reason this is here is because it\'s very important to communicate to others accurately what
you\'ve accomplished and what is left to accomplish. This sort of honesty and ability to appraise
your own work is a critical skill in a job.
Program Details
Individual RegistrationDetails
There are a two registration windows: early registration and regular registration. Prices for
registering early and regularly will be given. Each individual will have a unique number and
must be processed separately to record their name, age, running event, and donations raised. The
maximum number of runners for our program will be 10000.
Team RegistrationDetails
Teams may be created and registered to sign up several participators at once. Teams may only
sign up during early registration, have between 5 and 50 members, and must pay the team
registration fee for every member on the team. Teams should be recorded with their name and
number of members. Each member of the team still needs to be recorded with their name, age,
running event, and donations raised. We can organize at most 200 teams.
Running EventsDetails
There will be three running events: a 5k race, a 10k race, and a marathon race. For ea.

Why is the 16S rRNA gene a preferred marker for the identification, .pdf
Why is the 16S rRNA gene a preferred marker for the identification, classification, and
evolutionary history of microbes? Detail your answer based on 5 main characteristics of this
gene. In other words, for each of the 5 characteristics listed, provide a reason for why that is
important to make this gene a preferred one for this type of study. Lastly, are “functional” genes,
such as antibiotic resistant genes not appropriate to study evolutionary history of microbes?
the 5 things may include, its availability, its length, and its conserved and variable regions, and it
being acquired by vertical transfer. im hoping for this to be explained in a little more detail
because i dont really get the veritcal transder part of the bp (length) part.
thanks
Solution
Several aspects of the 16S rRNA gene make it a preferred marker for the identification,
classification, and evolutionary history of microbes. Firstly, because it is widespread among
prokaryotes. Secondly, it\'s size (1,550 bp long) and the high degree of functional conservation.
It is large enough to provide statistically valid measurements. The clock-like mutation rates
throughout prokaryotic evolution are the result of it’s high degree of functional conservation.
The Third aspect of the16S rRNA gene is that it is composed of both variable and conserved
regions. The conserved regions can be used for designing amplification primers across taxa
whereas, the nine hypervariable regions (V1-V9) can be effectively used for the comparative
taxonomy. Lastly, it is the most common gene to be used for constructing phylogenetic
relationships in prokaryotes as it is acquired by vertical transfer. It is universal in bacteria so
relationships can be measured among all bacteria but recently it has been argued that 16s rRNA
genes can also be transferred by horizontal gene transfer. It is important to make this gene a
preferred one for this type of study because 16S rRNA gene sequences analysis allow better,
accurate, robust and reproducible bacterial identification than that obtained by phenotypic
testing. The phenotypic test results are less subjective. It can identify poorly described, rarely
isolated, aberrant strains, and can also recognize novel pathogens. “Functional” genes, such as
antibiotic resistant genes are considered inappropriate to study the evolutionary history of
microbes because it is generally acquired by horizontal or lateral gene transfer. Many bacteria
become resistant by acquiring genes via horizontal gene transfer. Such genes in the organism
may show different rates of evolution or even show different evolutionary history. Often
Evolutionists point out the development of antibiotic resistance by bacteria as a validation of
evolutionary change but molecular analysis of the genetic events that lead to antibiotic resistance
do not support this assumption..
Why do SSDs benefit from a scheduler like noopSolutionThe def.pdf
Why do SSDs benefit from a scheduler like noop?
Solution
The default I/O scheduler for Linux is Completely Fair Queueing, and is a virtuous all-round
scheduler. Mutual wisdom holds that CFQ is needless or sub-optimal on systems that disrupt the
normal assumptions, such as hardware RAID cards equipped by a write-cache, or SSDs. In these
cases, the noop scheduler is recommended. The noop scheduler does nothing overlooking the
chance to optimize our disk admissions.
All our VPS hypervisors take hardware RAID cards with a write-cache, consequently we set out
to see if there were any improvements to be had from changing to the noop scheduler. Seeing by
way of we’d required it to roll out any large-scale alterations, we utilized Puppet to help us
discover some appropriate test subjects. By loading a custom Feature fact into our manifests, we
could clutch all the PCI IDs for RAID cards and see what representations were installed in
dissimilar servers. every smart RAID cards had the similar PCI ID, which parallels to the PERC

which of the following types of orgnisms possess the enzyme catalase.pdf
which of the following types of orgnisms possess the enzyme catalase?
A) obligate aerobe
B) obligate anaerobe
C) facultative anaerobe
D) both A & B
Solution
answer is A.
obligate aerobes are able to use oxygen as terminal electron acceptor during respiration contain
catalase.
obligate anaerobes even though possess catalase, it is very rare and in less quantities. facultative
anaerobes which ferment and does not respire using oxygen are also catalase negative.
facultative anaerobes under aerobic conditions possess catalase for aerobic respiration.

A laser beam strikes one end of a slab of material of length L = 42..pdf
A laser beam strikes one end of a slab of material of length L = 42.0 cm and thickness t=3.10
mm. Itenters the material at the center striking it at an angle of incidence of 50.0 degrees. The
index of refraction of the slab is n = 1.48. How many internal reflections the light makes from
the top and bottom of the slab before exiting at the other end.
Solution
As the beam enters the slab
n1*sin A1 = n2*sin A2
1*sin 50 = 1.48*sin A2
A2 = arcsin(sin 50/1.48) = 31.2 deg
the beam then stirkes at the top of slab at x1
x1 = 1.55*10^-3/tan 31.2 = 2.56*10^-3 m (from the left end)
After that the beam strike at slab each time it has traveled a distance of 2x1
Since the slab is 42 cm long, total distance to travel after first reflection = 42 cm - x1
(42 cm - x1)/2x1 = (42*10^-2 - 2.56*10^-3)/(2*2.56*10^-3) = 81.53 reflections
Since the number of reflection will be integer, So total number of reflections will be 82..

Transformation is the genetic alteration of a cell resulting from the direct uptake and
incorporation of exogenous genetic material from its surroundings through the cell membrane.
For transformation to take place, the recipient bacteria must be competent, that is should be in a
state to accept the foreign, naked DNA.
Transformation in bacteria was first demonstrated by Frederick Griffith in 1928. He discovered
that Streptococcus pneumoniae can be made virulent through exposure to heat inactivated
virulent strains. Later the transforming principle was found to be DNA..

While the Department was created to secure our country against those who seek to disrupt the
American way of life, our charter also includes preparation for and response to all hazards and
disasters.”
Explain both data warehouses and data mining and describe how they could be used in the DHS.
Solution
Data warehouse :
In computing, a data warehouse (DW or DWH), also known as an enterprise data warehouse
(EDW), is a system used for reporting and data analysis, and is considered a core component of
business intelligence.[DWs are central repositories of integrated data from one or more disparate
sources. They store current and historical data and are used for creating analytical reports for
knowledge workers throughout the enterprise. Examples of reports could range from annual and
quarterly comparisons and trends to detailed daily sales analysis.
The data stored in the warehouse is uploaded from the operational systems (such as marketing or
sales). The data may pass through an operational data store for additional operations before it is
used in the DW for reporting.
Data mining : Data mining is an interdisciplinary subfield of computer science. It is the
computational process of discovering patterns in large data sets involving methods at the
intersection of artificial intelligence, machine learning, statistics, and database systems.
The ways we can use data mining in DHS is :
1) Evaluating use of credit cards by people working in DHS
2)Evaluating patterns of security issues like cybercrime , any illegal transportation issues , mine
details about borde protection people
3)Identifying fraud activities in all departments if any
4)In forecasting of upcoming security issues based on past patterns using data mining
5)In call details analysis , to analyze all the incoming and outgoing calls if they are from people
who cause harm to the country
6)For detecting any malicious intrusions
7)Detect Attacks on critical infrastructurs if any

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.

cases, the noop scheduler is recommended. The noop scheduler does nothing overlooking the
chance to optimize our disk admissions.
All our VPS hypervisors take hardware RAID cards with a write-cache, consequently we set out
to see if there were any improvements to be had from changing to the noop scheduler. Seeing by
way of we’d required it to roll out any large-scale alterations, we utilized Puppet to help us
discover some appropriate test subjects. By loading a custom Feature fact into our manifests, we
could clutch all the PCI IDs for RAID cards and see what representations were installed in
dissimilar servers. every smart RAID cards had the similar PCI ID, which parallels to the PERC
H700 and H800 hardware..
which of the following types of orgnisms possess the enzyme catalase.pdf
which of the following types of orgnisms possess the enzyme catalase?
A) obligate aerobe
B) obligate anaerobe
C) facultative anaerobe
D) both A & B
Solution
answer is A.
obligate aerobes are able to use oxygen as terminal electron acceptor during respiration contain
catalase.
obligate anaerobes even though possess catalase, it is very rare and in less quantities. facultative
anaerobes which ferment and does not respire using oxygen are also catalase negative.
facultative anaerobes under aerobic conditions possess catalase for aerobic respiration.

A laser beam strikes one end of a slab of material of length L = 42..pdf
A laser beam strikes one end of a slab of material of length L = 42.0 cm and thickness t=3.10
mm. Itenters the material at the center striking it at an angle of incidence of 50.0 degrees. The
index of refraction of the slab is n = 1.48. How many internal reflections the light makes from
the top and bottom of the slab before exiting at the other end.
Solution
As the beam enters the slab
n1*sin A1 = n2*sin A2
1*sin 50 = 1.48*sin A2
A2 = arcsin(sin 50/1.48) = 31.2 deg
the beam then stirkes at the top of slab at x1
x1 = 1.55*10^-3/tan 31.2 = 2.56*10^-3 m (from the left end)
After that the beam strike at slab each time it has traveled a distance of 2x1
Since the slab is 42 cm long, total distance to travel after first reflection = 42 cm - x1
(42 cm - x1)/2x1 = (42*10^-2 - 2.56*10^-3)/(2*2.56*10^-3) = 81.53 reflections
Since the number of reflection will be integer, So total number of reflections will be 82..

D. Proteins
Solution
Answer:
18. (B) DNA
Transformation is the genetic alteration of a cell resulting from the direct uptake and
incorporation of exogenous genetic material from its surroundings through the cell membrane.
For transformation to take place, the recipient bacteria must be competent, that is should be in a
state to accept the foreign, naked DNA.
Transformation in bacteria was first demonstrated by Frederick Griffith in 1928. He discovered
that Streptococcus pneumoniae can be made virulent through exposure to heat inactivated
virulent strains. Later the transforming principle was found to be DNA..
The Department of Homeland Security (DHS) consists of U.S. Customs a.pdf
The Department of Homeland Security (DHS) consists of U.S. Customs and Border Protection,
Federal Emergency Management Agency, U.S. Immigration and Customs Enforcement,
Transportation Security Administration, United States Coast Guard and the United States Secret
Service.
The DHS strategic plan states: “The Department of Homeland Security’s overriding and urgent
mission is to lead the unified national effort to secure the country and preserve our freedoms.
While the Department was created to secure our country against those who seek to disrupt the
American way of life, our charter also includes preparation for and response to all hazards and
disasters.”
Explain both data warehouses and data mining and describe how they could be used in the DHS.
Solution
Data warehouse :
In computing, a data warehouse (DW or DWH), also known as an enterprise data warehouse
(EDW), is a system used for reporting and data analysis, and is considered a core component of
business intelligence.[DWs are central repositories of integrated data from one or more disparate
sources. They store current and historical data and are used for creating analytical reports for
knowledge workers throughout the enterprise. Examples of reports could range from annual and
quarterly comparisons and trends to detailed daily sales analysis.
The data stored in the warehouse is uploaded from the operational systems (such as marketing or
sales). The data may pass through an operational data store for additional operations before it is
used in the DW for reporting.
Data mining : Data mining is an interdisciplinary subfield of computer science. It is the
computational process of discovering patterns in large data sets involving methods at the
intersection of artificial intelligence, machine learning, statistics, and database systems.
The ways we can use data mining in DHS is :
1) Evaluating use of credit cards by people working in DHS
2)Evaluating patterns of security issues like cybercrime , any illegal transportation issues , mine
details about borde protection people
3)Identifying fraud activities in all departments if any
4)In forecasting of upcoming security issues based on past patterns using data mining
5)In call details analysis , to analyze all the incoming and outgoing calls if they are from people
who cause harm to the country
6)For detecting any malicious intrusions
7)Detect Attacks on critical infrastructurs if any
Data warehousing in dHS : A data warehouse is a collection of data that\'s:.

Select all that apply! We are trying to determine the possible modes.pdf
Select all that apply! We are trying to determine the possible modes of inheritance for some
particular human disorder. We have a very small pedigree for this disorder. Assuming the
pedigree is accurate, indicate which of the six modes of inheritance are consistent with this
pedigree: Select one or more: X-Linked Dominant Autosomal Dominant X-Linked Recessive
Cytoplasmic Y Linked Autosomal Recessive
Solution
the analysis of this rpedigree shows that the inheritance pattern is X linked. ONly because the
offsprings are affected when parents genotgype
Tje imheritance is X linked dominant because, for pesence of one dominant gene for the afetcted
phentype in male,, The make individuals are affected. This is therefore not a recessive
inheritance In later case, the affected phenotype will be seen only if the two genes are present at
the same time..

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.

Child centred education is an educational approach that priorities the interest, needs and abilities of the child in the learning process.
Embracing GenAI - A Strategic Imperative
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.
