A number of monks live in a monastery and they do not communicate in a.docx
A number of monks live in a monastery and they do not communicate in any way. Monks gather just once a day in the prayer hall; there are no mirrors and monks never see their own faces. A disease is ravaging the land; its first visible sign is a mark on the forehead of the victim. The disease causes no discomfort initially but it is eventually so painful that anyone who has acquired it will immediately commit suicide. A visitor one day announces:
Solution
there are a lot of variations to this. unfortunately, this is a bad variation since suicide depends on their own pain threshold, not on knowing if they have the disease. There\'s one about prisoners with hats, another about an island.
however, assuming they commit suicide as soon as they realize they have the mark, and they trust the visitor not to lie, i\'ll do the first one.
i see the other person is marked. two possibilities: 1) i have the mark, 2) i don\'t have the mark.
Suppose 2). if i dont have the mark, the other person knows he has the mark since at least one of the two has it, and he will die immediately.
However, he doesn\'t commit suicide. That must mean he\'s not sure if he has the mark. The only way he\'s not sure is because I also have the mark. So I die after i realize he\'s not dying. Since I waited before dying, he knows he has the mark as well, and dies afterwards.
I\'ll let you do the rest.

A molecule or ion that donates the hydrogen in a hydrogen bond is a hy (1).docx
A molecule or ion that donates the hydrogen in a hydrogen bond is a hydrogen bond donor A molecule or ion that binds to this hydrogen is a hydrogen bond acceptor. Specify the hydrogen bonding behavior of the 4 species below by selecting: donor for species that act as donors only acceptor for species that act as acceptors only both for species that act as both donors and acceptors neither for species that act neither as donors nor as acceptors. Hydrogen bonding behavior SiH3 ??? Hydrogen bonding behavior O: HN Hydrogen bonding behavior Hydrogen bonding behavior CH3
Solution
The species which acts as a hydrogen acceptor must have a lone pair to attract the electron deficient H + ion.
The species which acts as a hydrogen donor must be more electronegative than hydrogen so that bonding electrons are retained with the species and electron deficient H + ion is released.
In the question,
1st species : Hydrogen bond behavior neither (no lone pair of electrons)
2nd species: Hydrogen bond behavior neither (no lone pair of electrons)
3rd species: Hydrogen bond behavior both ( Nitrogen is both acceptor & donor and oxygen is only acceptor)
4th species: Hydrogen bond behavior neither (no lone pair of electrons)

A Martian leaves Mars in a spaceship that is heading to Venus- On the.docx
A Martian leaves Mars in a spaceship that is heading to Venus. On the way, the spaceship passes earth with a speed v = 0.77c relative to it. Assume that the three planets do not move relative to each other during the trip. The distance between Mars and Venus is 1.20 × 1011 m, as measured by a person on earth. (a) What does the Martian measure for the distance between Mars and Venus? (b) What is the time of the trip (in seconds) as measured by the Martian? Limit your answer to 2 significant digits.
Solution
the three planets can be thought to be stationary.
distance between mass and venus=d1=1.2*10^11 m
part a:
using length contraction, distance measured by the martian=1.2*10^11*sqrt(1-(v/c)^2)
=7.6565*10^10 m
part b:
time of the trip by martian=distance measured by martian/speed
=7.6565*10^10/(0.77*3*10^8)
=331.45 seconds

A leadership/motivation case is provided below. The case includes important leadership issues including, but not limited to, motivation, ethical decision-making, communication, establishing an organizational culture, and managing change. The case allows students to apply what has been learned in this course about leadership and motivation.
Part I
Required Elements to include in the Leadership Scenario:
Two important considerations:
Solution
Leadership Theories
Trait Theory
This theory postulates that people are either born or not born with the qualities that predispose them to success in leadership roles. That is, that certain inherited qualities, such as personality and cognitive ability, are what underlie effective leadership. There have been hundreds of studies to determine the most important leadership traits, and while there is always going to be some disagreement, intelligence, sociability, and drive (aka determination) are consistently cited as key qualities.
Skills Theory
This theory states that learned knowledge and acquired skills/abilities are significant factors in the practice of effective leadership. Skills theory by no means disavows the connection between inherited traits and the capacity to be an effective leader

A kettle is filled with tap water and placed on a stove- The stove ele.docx
A kettle is filled with tap water and placed on a stove. The stove element is turned on. Explain why the water starts to boil after a while.
Solution
Water boil due a mode of transfer of heat is called convection.
Explanation-
Convection is mode of transfer of heat from one region to another due to bulk movement of particles of medium under the temperature difference.
when stove is tuned on, heat reach from flame of stove to the container of water due to radiation. Now, heat moves from outer surface of bottom of container to inner side ( water side) due to conduction process.
Since, bottom of container has the higher temperature to top surface. So, bottom part of water gains heat due to which its density decreases slighly comparision to the upper part of the water, because of which, these two parts of water ( upper and top) gain some movement. Since, any material moves from higher density to lower density under the gravity. By this way, upper part of water ( which has higher density comparision to lower) moves downward and bottom part of water moves upward taking the heat energy with themselves.
Thus, a cycle forms. Bottom part moves upward taking the heat energy and top part moves downward. This process continues further. By this way, water boil when stove is turned on.

There were a number of loose ends from the first two series, and changes in the third series, that were explained off by a text intro to the first show of Series III. This was done in the form of scrolling text across outer space, in a parody of the introductions to the Star Wars movies. The loose ends included the return of Kryten, Lister being pregnant, delivering twins Jim and Bexley, who grow up in a matter of days, then wind up in the parallel universe with the female version of Lister.
The regular cast changed for Series III: Robert Llewellyn came in as Kryten, and Hattie Hayridge replaced the departing Lovett. [26] Craig Charles, Chris Barrie and Danny John-Jules remained as Lister, Rimmer and Cat respectively. [27]
The character of Kryten was originally intended as a one-off appearance in the series-two episode \"Kryten\", but had returned mainly to broaden the story potential. The show was becoming difficult to write for. At the insistence of Naylor, Kryten returned to complete the team. [28] They had approached David Ross with the intention of bringing him back to play the regular role of Kryten. Ross, however, was in a stage play Flea In Her Ear and was not available, so they went to see Robert Llewellyn. Llewellyn was also in a stage show called Mammon: Robot Born of Woman , playing a robot. They saw his performance and were impressedhis book actually began with another book

Consider the plane R2 and consider any two lines that pass through the.docx
Consider the plane R 2 and consider any two lines that pass through the origin. Are these lines subspaces of the plane? Are they isomorphic? Are they \"the same\"? Clearly the \"look different\", but mathematically, do they behave the same structurally?
Thank you, Please show work
Solution
1 . lines cannot be subspaces , they can be made boundaries of a sub space,In rough terms we can call them a subspaces of zero area. 2 . for two graphs to be isomorphic,the relation between output of one graph and input of the other graph must be a bijection.in easy terms for every value of input taken for 2nd graph from the output values of the first, there should be a unique output.as it is a real plane and both are straight lines passiing through orign,both lines are isomorphic 3 . They are absolutely not same but the behaviour will same as i)they have no intercepts ii) they have constant slopes these two propertes make them structurally similar

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.

Consider the plane R2 and consider any two lines that pass through the.docx
Consider the plane R 2 and consider any two lines that pass through the origin. Are these lines subspaces of the plane? Are they isomorphic? Are they \"the same\"? Clearly the \"look different\", but mathematically, do they behave the same structurally?
Thank you, Please show work
Solution
1 . lines cannot be subspaces , they can be made boundaries of a sub space,In rough terms we can call them a subspaces of zero area. 2 . for two graphs to be isomorphic,the relation between output of one graph and input of the other graph must be a bijection.in easy terms for every value of input taken for 2nd graph from the output values of the first, there should be a unique output.as it is a real plane and both are straight lines passiing through orign,both lines are isomorphic 3 . They are absolutely not same but the behaviour will same as i)they have no intercepts ii) they have constant slopes these two propertes make them structurally similar

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.

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...
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
