In April 2013, Procter & Gamble (P&G), the world’s largest consumer packaged goods (CPG) company, announced that it would extend its payment terms to suppliers by 30 days. At the same time, P&G announced a new supply chain financing (SCF) program giving suppliers the ability to receive discounted payments for their P&G receivables. Fibria Celulose, a Brazilian supplier of kraft pulp, joined the program in 2013 but was re-evaluating the costs and benefits of participating in the SCF program in the summer of 2015. The firm’s treasury group and its US country manager must decide whether to keep using the program and, if so, whether to keep their existing SCF banking relationship or start a new relationship with another global SCF bank.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Embracing GenAI - A Strategic ImperativePeter Windle
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.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

1. Learning Objectives
• Determine when to use sampling.
• Determine the pros and cons of various sampling
techniques.
• Be aware of the different types of errors that can
occur in a study.
• Understand the impact of the Central Limit
Theorem on statistical analysis.
• Use the sampling distributions of the sample
mean and sample proportion.
2. Reasons for Sampling
• Sampling – A means for gathering information
about a population without conducting a
census
– Information is gathered from sample, and
inference is made about the population
• Sampling has advantages over a census
– Sampling can save money.
– Sampling can save time.
3. Random versus non-random Sampling
• Nonrandom Sampling - Every unit of the
population does not have the same
probability of being included in the sample
• Random sampling - Every unit of the
population has the same probability of being
included in the sample.
4. Sampling from a Frame
• A sample is taken from a population list, map ,
directory, or other source used to represent
the population, which is called a frame.
• Frames can be Telephone Directory, School
lists, trade association lists, or even lists sold
by brokers.
• In theory, the target population and the frame
are same. But in reality, frames may have
over-registration or under-registration.
5. Random Sampling Techniques
• Simple Random Sampling – basis for other
random sampling techniques
– Each unit is numbered from 1 to N (the size of the
population)
– A random number generator can be used to select
n items that form the sample
– Easier to perform on small populations. The
process of numbering all members of a population
is cumbersome for large populations
6. Random Sampling Techniques
• Systematic Random Sampling
– Every kth item is selected to produce a sample of
size n from a population of size N
– Value of k is called sampling cycle
– Define k = N/n. Choose one random unit from
first k units, and then select every kth unit from
there
– Used because of convenience and relative ease of
administration
– A knowledgeable person can easily determine
whether a sampling plan has been followed.
7. Systematic Random Sampling:
Example
• Purchase orders for the previous fiscal year are
serialized 1 to 10,000 (N = 10,000).
• A sample of fifty (n = 50) purchases orders is
needed for an audit.
• k = 10,000/50 = 200
8. Systematic Sampling: Example
• First sample element randomly selected from the
first 200 purchase orders. Assume the 45th
purchase order was selected.
• Subsequent sample elements: 45, 245, 445, 645, . . .
9. Random Sampling Techniques
• Systematic Random Sampling: Problems
– Problems can occur if the data are subject to any
periodicity and the sampling interval is in
syncopation with it, and sampling will be nonrandom
– Example: a list of 150 college students, actually a
merged list of 5 classes with 30 students in each
class, the list in each class being ordered with
names of top students first and bottom students
last. Systematic sampling of every 30th student
may cause selection of all top or bottom or
mediocre students i.e. the list is subject to cyclical
organizations
10. Random Sampling Techniques
• Stratified Random Sampling
– The population is broken down into strata i.e.
homogeneous segments with like characteristics (i.e.
men and women OR old, young, and middle-aged
people, OR high-income, mid-income and low-income
group ) and then Simple/Systematic Random Sampling
is done.
– Efficient when differences between strata exist
– The technique capitalizes on the known homogeneity
of subpopulations so that only relatively small
samples are required to estimate the characteristic for
each stratum or group
– Proportionate (% of the sample from each stratum
equals % that subpopulation of each stratum is within
the whole population)
11. Random Sampling Techniques
• Cluster (or Area) Sampling
– The population is in pre-determined clusters (students
in classes, colleges, towns, companies, areas of a city,
geographic regions etc.)
– The technique identifies clusters that tend to be
internally heterogeneous
– Each cluster contains a wide variety of elements, and
is miniature of the population
– A random sample of clusters is chosen and all or some
units within the cluster is used as the sample
– Advantages: Convenience and Cost, Convenient to
obtain and cost of sampling is reduced as the scope of
study is reduced to clusters
12. Random Sampling Techniques
Important to remember:
in Stratified Random Sampling, each stratum is a
homogeneous group of population
in Cluster Sampling, each cluster is a
heterogeneous group of population
13. Convenience (NonRandom) Sampling
• Non-Random sampling – sampling techniques
used to select elements from the population by
any mechanism that does not involve a random
selection process
– These techniques are not desirable for making
statistical inferences
– Example – choosing members of this class as an
accurate representation of all students at our
university, selecting the first five people that walk into
a store and ask them about their shopping
preferences, etc.
14. Non-sampling Errors
• Non-sampling Errors – all errors that exist
other than the variation expected due to
random sampling
– Missing data, data entry, and analysis errors
– Leading questions, poorly conceived
concepts, unclear definitions, and defective
questionnaires
– Response errors occur when people do not
know, will not say, or overstate in their answers
15. Proper analysis and interpretation of a sample statistic
requires knowledge of its distribution.
Process of
Inferential Statistics
Select a
random sample
16. What is a Sampling Distribution?
• Recall that Statistic has a numerical value that can be
computed (observed) once a sample data set is
available.
• Three points are crucial in this context:
Because a sample is only a part of the population, the
numerical value of a statistic cannot be expected to
give us the exact value of the parameter
The observed value of a statistic depends on the
particular sample that happens to be selected
There will be some variability in the observed values
of a statistic over different occasions of sampling
17. What is a Sampling Distribution?
• The value of a Statistic varies in repeated sampling.
• In other words, a Statistic is a random variable and
hence has its own probability distribution
• Sampling Distribution is the Probability Distribution
of a Statistic
• The qualifier Sampling indicates that the distribution
is conceived in the context of repeated sampling from
a population
• The qualifier is often dropped to say the distribution
of a statistic
18. Statistic and Sampling Distribution
• In any given situation, we are often limited to one
sample and the corresponding single observed value
of a statistic
• However, over different samples the statistic varies
according to its sampling distribution
• The sampling distribution of a statistic is determined
- from the probability distribution f(x) that governs
the population
- sample size n
19. Central Limit Theorem
• Consider taking a sample of size n from a population
• The sampling distribution of the sample mean is the
distribution of the means of repeated samples of size
n from a population
• The central limit theorem states that as the sample
size increases,
The shape of the distribution becomes a normal
distribution (this condition is typically considered
to be met when n is at least 30)
The variance decreases by a factor of n
20. Sampling from a Normal Population
The distribution of sample means is normal for
any sample size.
21. z Formula for Sample Means
The distribution of sample means is normal for
any sample size.
22. Tyre Store Example
Suppose that the mean expenditure per customer at a
tyre store is $85.00, with a standard deviation of
$9.00. If a random sample of 40 customers is taken,
what is the probability that the sample average
expenditure per customer for this sample will be
$87.00 or more?
Solution: Because the sample size is greater than 30,
the central limit theorem can be used to state that the
sample mean is normally distributed and the problem
can proceed using the normal distribution calculations.
