In January 2000 you began a one-year study of tuberculosis (TB) in a subsidized housing
community in the Lower East Side of New York City. You enrolled 500 residents in your study
and checked on their TB status on a monthly basis. At the start of your study on January 1st, you
screened all 500 residents. Upon screening, you found that 20 of the healthy residents were
immigrants who were vaccinated for TB and so were not at risk. Another 30 residents already
had existing cases of TB on January 1st. On February 1st, 5 residents developed TB. On April
1st, 5 more residents developed TB. On June 1st, 10 healthy residents moved away from New
York City were lost to follow-up. On July 1st, 10 of the residents who had existing TB on
January 1st died from their disease. The study ended on December 31, 2000. Assume that once a
person gets TB, they have it for the duration of the study, and assume that all remaining residents
stayed healthy and were not lost to follow-up.
What was the case-fatality rate among residents with TB over the course of the year? (Points: 2)
10/500, or 1.02%
10/40, or 25%
10/30, or 33%
10/450, or 2.2%
Solution
10/40, or 25%.

Impacts of Covid 19 on Human Existence in the Contemporary Worldijtsrd
The COVID 19pandemictook the 2020 world by storm and shook it to the foundations. It hit the world without premonitions, spread faster than wild fire and struck with malignant ferociousness. What started as a puzzle in late 2019 became a full pandemic in 2020, throwing the entire world into a frenzy of panic and confusion. Nation after nation went into lockdown. The entire world raced for remedy. Hundreds of thousands became ill within weeks. Existence of humans became threatened worldwide. People’s mode of living forcefully changed. Death became imminent. Uncertainty hovered over human existence. The meaning of existence came under question as the world grappled with the malignant virus.

what is natural ventilation? could you please explain in detail but with not many jargon?
Solution
Natural forces (e.g. winds and thermal buoyancy force due to indoor and outdoor air density
differences) drive outdoor air through purpose-built, building envelope openings. Purpose-built
openings include windows, doors, solar chimneys, wind towers and trickle ventilators. This
natural ventilation of buildings depends on climate, building design and human
behaviour.Natural ventilation is the process of supplying and removing air through an indoor
space by natural means, meaning without the use of a fan or other mechanical system. It uses
outdoor air flow caused by pressure differences between the building and its surrounding to
provide ventilation and space cooling..

What is s(t) if s\'(t)=36t^5+4t^3?
Solution
According to the rule, s(t) could be determined evaluating the indefinite integral of s\'(t)
Int (36t^5+4t^3)dt
We\'ll apply the additive property of integrals:
Int (36t^5+4t^3)dt = Int (36 t^5)dt + Int (4 t^3)dt
We\'ll re-write the sum of integrals, taking out the constants:
Int (36t^5+4t^3)dt = 36 Int t^5 dt + 4Int t^3 dt
Int (36t^5+4t^3)dt = 36*x^6/6 + 4*x^4/4
We\'ll simplify and we\'ll get:
Int (36t^5+4t^3)dt = 6x^6 + x^4 + C
The function s(t) is:s(t) = 6x^6 + x^4 + C.

In my class we are studying pi. I dont understand it. Could someon.pdfanantakoli2000
In my class we are studying pi. I don\'t understand it. Could someone please explain it to me?
Solution
Pi (from the greek word that means \'periphery\') is simply a ratio, or a fraction of the
circumference (distance around a circle) to its diameter (distance across a circle) or
1) circumference / diameter, or c/d
One of the properties of all circles, no matter how large or small, is that the fraction of
circumference and diameter will always reduce to 22/7, so if the distance around a circle is
measured as 22, the diameter of that same circle is always 7. If the diameter is 14, the
circumference is always 44, and so on. However, since 22/7 is simply a fraction, although a very
special one, it can be represented in decimal form
2) 22/7 = 3.1416....
Since 22 divided by 7 doesn\'t come out evenly, the number goes on forever, but rounding it to 4
digits is usually good enough for calculations. So this 22/7 fraction, or this 3.1416 decimal
number, is given the special name of Pi..

In morse code, a series of dots and dashes are sent to create coded .pdfanantakoli2000
In morse code, a series of dots and dashes are sent to create coded messages. In this code, dashes
are slightly more common than dots, specifically, P(dot sent) = 3/7 and P(dash sent) = 4/7. Due
to interference, sometimes errors can occur in transmission. Suppose that the probability that a
dot is received given that a dot has been sent is 7/8, and the same probablility holds true for a
dash. If we receive a dot, how sure are we that a dot was sent? To answer this, find P(dot sent|dot
received).
Solution
P(dot received) = P(dot sent)*P(no error) + P(dash sent)*P(error) = 3/7*7/8 + 4/7*1/8 = 25/56
P(dot sent |dot received) = (3/7*7/8) / (25/56) = 21/25 = 0.84.

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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
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

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
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.
