The social media app you are designing a database for allows Users to.pdfStewartxCYTurnerq
The social media app you are designing a database for allows Users to share two kinds of
content: **Messages** and **Stories**.
Tables structure
Decide what fields and data types are necessary for the two tables necessary for this app: `users`
and `posts`. The `posts` table stores both Messages and Stories.
Bear in mind that the application must be able to use these tables to perform the required
functionality outlined below.
Users:
Users can register for the app by supplying their...
- email
- password
- handle (i.e. username).
Messages:
- Messages consist of text only.
- Messages are sent from one user to another specific user.
- Messages become invisible immediately after view and don't show up in the app thereafter.
- Messages are never actually deleted from the database table, even when invisible to the user
(the social media company that produces the app keeps 'deleted' content in its database for future
data harvesting, monetization purposes, and more.)
Stories:
- Stories consist of text only.
- Stories are public and every user can see them.
- Stories become invisible 24 hours after posting and don't show up in the app thereafter.
- Stories are never deleted from the database table, even when invisible to the user.
Write the SQL command to create these tables with the structure you determine is necessary.
### Practice data
Insert realistic-looking dummy data for one thousand Users, one thousand Messages, and one
thousand Stories.
Include the practice data in CSV files named `users.csv` and `posts.csv` in the directory named
`data`.
Write the SQLite commands necessary to import the data into the respective tables.
### Queries
Write a single SQL query to perform each of the followin tasks:
1. Register a new User.
1. Create a new Message sent by a particular User to a particular User (pick any two Users for
example).
1. Create a new Story by a particular User (pick any User for example).
1. Show the 10 most recent visible Messages and Stories, in order of recency.
1. Show the 10 most recent visible Messages sent by a particular User to a particular User (pick
any two Users for example), in order of recency.
1. Make all Stories that are more than 24 hours old invisible.
1. Show all invisible Messages and Stories, in order of recency.
1. Show the number of posts by each User.
1. Show the post text and email address of all posts and the User who made them within the last
24 hours.
1. Show the email addresses of all Users who have not posted anything yet.
### Hint
The following SQLite code returns the difference in hours between the time now and an earlier
date and time - this may be useful in determining the number of hours that have passed since a
post was made: `ROUND((JULIANDAY('now') - JULIANDAY('2021-02-21 12:50:00')) * 24)`
To see the return value of this command directly (not as part of a comparison operation), use the
following syntax: `SELECT ROUND((JULIANDAY('now') - JULIANDAY('2021-02-21
12:50:00')) * 24);`

The Saint Lucia Blood Bank- a private charity partly supported by gove.pdfStewartxCYTurnerq
The Saint Lucia Blood Bank, a private charity partly supported by government grants, is located
on the Caribbean island of Saint Lucia. The blood bank has just finished its operations for
September, which was a very busy month due to a powerful hurricane that hit neighboring
islands causing many injuries. The hurricane largely bypassed Saint Lucia, but residents of Saint
Lucia willingly donated their blood to help people on other islands. As a consequence, the blood
bank collected and processed over 20% more blood than had been originally planned for the
month. A report prepared by a government official comparing actual costs to budgeted costs for
the blood bank appears below. Continued support from the government depends on the blood
bank's ability to demonstrate control over its costs. The managing director of the blood bank was
very unhappy with this report, claiming that his costs were higher than expected due to the
emergency on the neighboring islands. He also pointed out that the additional costs had been
fully covered by payments from grateful recipients on the other islands. The government official
who prepared the report countered that all of the figures had been submitted by the blood bank to
the government; he was just pointing out that actual costs were a lot higher than promised in the
budget. The following cost formulas were used to construct the planning budget: Required:
1.Complete the flexible budget performance report for September. (Indicate the effect of each
variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero

The Saint Lucia Blood Bank- a private charity partly supported by gove.pdfStewartxCYTurnerq
The Saint Lucia Blood Bank, a private charity partly supported by government grants, is located
on the Caribbean island of Saint Lucia. The blood bank has just finished its operations for
September, which was a very busy month due to a powerful hurricane that hit neighboring
islands causing many injuries. The hurricane largely bypassed Saint Lucia, but residents of Saint
Lucia willingly donated their blood to help people on other islands. As a consequence, the blood
bank collected and processed over 20% more blood than had been originally planned for the
month. A report prepared by a government official comparing actual costs to budgeted costs for
the blood bank appears below. Continued support from the government depends on the blood
bank's ability to demonstrate control over its costs. The managing director of the blood bank was
very unhappy with this report, claiming that his costs were higher than expected due to the
emergency on the neighboring islands. He also pointed out that the additional costs had been
fully covered by payments from grateful recipients on the other islands. The government official
who prepared the report countered that all of the figures had been submitted by the blood bank to
the government; he was just pointing out that actual costs were a lot higher than promised in the
budget. The following cost formulas were used to construct the planning budget: Required:
1.Complete the flexible budget performance report for September. (Indicate the effect of each
variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero
variance). Input all amounts as positive values.).

The reason why Copernicus's heliocentric theory eventually came to be.pdfStewartxCYTurnerq
The reason why Copernicus's heliocentric theory eventually came to be regarded as preferable to
the geocentric theory of Ptolemy is that the heliocentric theory accounted for the same observed
motions of the planets as the geocentric theory but did so in a much simpler way. accounted for
the same observed motions of the planets as the geocentric theory but did so much more
complicated way. used complex constructions called epicycles and deferents to account for the
observed motions of the planets and so was considered more reliable than the geocentric theory.

The reason the medical community prefers to use the term -sexually tra.pdfStewartxCYTurnerq
The reason the medical community prefers to use the term "sexually transmitted infection" (STI)
rather than "sexually transmitted disease" is because: a) infections don't always result in disease
symptoms or signs b) the term "infection" tends to be less stigmatized than "disease," and may
make it more likely for people to seek medical care c) infections may progress to become
diseases, but only if the correct set of conditions exists to do so d) all of the above.

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.
The switch below has six nodes directly connected to it and a forwardi.pdf
1. The switch below has six nodes directly connected to it and a forwarding table that can hold ten
entries. Suppose that node B sends 20 frames to node C every second at a steady rate, and
whenever C receives four of these frames, it sends a single frame in response. No frames are lost
or corrupted and nodes D , E and F are not communicating. Assume that node A is compromised,
how many frames from B's communication with C can A eavesdrop? Explain why. Consider
both directions of the communication, and assume the switch starts with an empty forwarding
table (Hint: consider what frames will be broadcast).
