This document provides guidance on evaluating information sources using the C.A.R.P. test - evaluating sources for Currency, Accuracy, Reliability, and Purpose. It examines how to apply this test to different resource types like websites, government reports, journal articles, and provides tips for evaluating specific resources. Key factors include checking publication dates, author qualifications, peer-review status, and domain names for websites. Government and peer-reviewed journal articles generally require less careful evaluation than other sources like commercial websites. The document aims to teach readers how to critically assess sources to determine their usefulness and trustworthiness.

Slide 1: A Predictive Analytics Primer by Thomas H. Davenport
Slide 2: Thomas H. Davenport
Slide 3: Powers of Predictive analytics
Slide 4: Predictive analytics refers to predicting future from the data of the past.
Slide 5: The quantitative analysis isn’t magic—but it is normally done with a lot of past data, a little statistical wizardry, and some important assumptions.
Slide 6: The Data: Lack of good data is the most common barrier to organizations seeking to employ predictive analytics.
Slide 7: The Statistics: Regression analysis in its various forms is the primary tool that organizations use for predictive analytics.
Slide 8: An analyst hypothesizes that a set of independent variables (say, gender, income, visits to a website) are statistically correlated with the purchase of a product for a sample of customers. The analyst performs a regression analysis to see just how correlated each variable is; this usually requires some iteration to find the right combination of variables and the best model.
Slide 9: The Assumptions: That brings us to the other key factor in any predictive model—the assumptions that underlie it. Every model has them, and it’s important to know what they are and monitor whether they are still true. The big assumption in predictive analytics is that the future will continue to be like the past.
Slide 10: What can make assumptions invalid?
Slide 11: The most common reason is time. If your model was created several years ago, it may no longer accurately predict current behavior. The greater the elapsed time, the more likely customer behavior has changed.
Slide 12: Another reason a predictive model’s assumptions may no longer be valid is if the analyst didn’t include a key variable in the model, and that variable has changed substantially over time.
Slide 13: Managers should always ask analysts what the key assumptions are, and what would have to happen for them to no longer be valid. And both managers and analysts should continually monitor the world to see if key factors involved in assumptions might have changed over time.
Slide 14: With these fundamentals in mind, here are a few good questions to ask your analysts:
Can you tell me something about the source of data you used in your analysis?
Are you sure the sample data are representative of the population?
Are there any outliers in your data distribution? How did they affect the results?
What assumptions are behind your analysis?
Are there any conditions that would make your assumptions invalid?
Slide 15: Thank You!

Treatment of alopecia or hair loss is directly related to its cause. A healthy hair follicle can produce a healthy hair. So in regards to treatment of hair loss or alopecia the treatment which treats the causative ailments can give a long standing and established result. A proper homeopathy treatment can be proved most beneficial for the treatment of any type of hair loss as homeopathy treats the root cause of any health disorders.
Hair loss due to any mental and physical stress can be well treated by proper homeopathy treatment as homeopathy medicines gives good impact on psychological and spiritual level thus helps to maintain a healthy mental condition and indirectly regulate to maintain a healthy balance of stress hormones in our body. Over secretion of stress hormones can put bad impact over the hair follicles.
Many drugs like anti cancer drugs (chemo therapy) and so many other drugs have strong side effects on the body including hair follicles. So they destroy the healthy atmosphere of the hair follicles and cause the immature massive hair loss. A proper homeopathy treatment can neutralize the toxic effects of those strong chemical drugs and also helps to accelerate the body’s auto detoxification process thus can be proved beneficial to check such type of drug induced hair loss. The homeopathy treatment not only check the hair loss ailments but also treats the person as a whole so make the person healthy as well.
Many health disorders likes tinea infection on scalp, lichen planus of scalp, psoriasis can causes hair loss. A proper homeopathy treatment can cure such diseases permanently and as well helps to treat the hair fall effectively. The important point in homeopathy treatment that it treats the person as a whole so make the person healthy not only to any specific body part but to the whole person and more over without giving any drug side effects. But homeopathy does not have any specific medicines for any specific ailments. The medicines are selected on totality of symptoms basis. So a well qualified and experienced homeopath can give a better treatment for any health issues.
Some women after child birth or during approach of menopause experiences of massive hair fall result from hormonal changes. Any hormonal treatment in those cases will not give the satisfactory results to check the hair loss. But well selected homeopathy medicines in this case not only be able to check the hair loss problem but also be helpful to cure all other associated problems as well.
In addition to a good homeopathy treatment a healthy nutrition habit is also highly required for a healthy hair and hair follicle. A low protein and iron deficient diet can make your hair weak and thin. So a well balanced natural diet is strongly advisable for healthy hairs

A Strategic Approach: GenAI in EducationPeter 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 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.

Evaluating resources
1. Evaluating Information
Great! You’ve found some resources you think will help
answer your question. Now what?
You need to evaluate them to make sure they are useful,
reliable and appropriate for your topic.
Laura Sloane 2015
2. C.A.R.P Test
You can evaluate all types of resources—websites, journal
articles, government reports or other documents—using
the same simple test, known as the C.A.R.P test
• CURRENCY
• ACCURACY
• RELIABILITY
• PURPOSE
Let’s look at this in more detail…
3. • When was it written? Is it still in date for
your topic?
• Is historical or current information
required to answer your question?
• Who wrote it?
• Are they qualified to have an opinion on
this topic?
• Is the source trustworthy?
• Does the author support their argument
with references?
• What is the perspective of the piece?
• Does it push an opinion or is it factual?
5. Websites
The internet is a fantastic
search tool which you
shouldn’t be afraid of
using. However, because
anyone can publish a
webpage and say whatever
they want, it needs to be
more carefully evaluating
than other resources.
The New Yorker cartoon by Peter
Steiner, July 5, 1993.Image from Wikipedia
6. One way to evaluate a website if by
checking the domain name to see who has
published it:
Most Reliable Evaluate carefully Best avoided
.edu (educational
sites)
.gov (government)
.ac (academic)
.org (organizations)
.net (networks)
.asn (association)
.com (commercial
websites)
Also check for an identifiable author, publication
or update date and any references or links
provided
TIP! Play it safe. If you’re not sure about
the reliability of a website, it is best to
steer clear.
7. Government Resources
Government resources are assumed to be
reliable, given that their main role is to provide
accurate information to Parliament or the public.
In fact, they can be some of the most useful
sources as they are normally comprehensive and
up to date.
However, they still need to be evaluated. A research
report will have very different content and purpose to
a press release by a Minister. So keep in mind
C.A.R.P principles—particularly with regards to the
purpose of the information
8. Journal Articles
Is it peer reviewed?
A peer reviewed journal has been through a
formal process where it is evaluated by subject
specialists before publication. In this process
they check that what the journal has to say is
accurate and appropriately researched.
Most databases will have an option in advanced
search to limit your results to peer reviewed articles,
but the best way is to use the Ulrichsweb database
9. Using Ulrichsweb
To use Ulrichsweb, simply type the journal title in the search bar
and click the search icon
The referee jumper indicates that the journal is peer reviewed
10. If you click on the title of the journal it will give
you more information:
11. Remember!
You can always ask a librarian if you need help evaluating
resources or using Ulrichsweb
