12-19 Notes Compare and contrast the Hubble Space Telescope with James.docxtodd991
12:19 Notes Compare and contrast the Hubble Space Telescope with James Webb Space Telescope (JwST).
Solution
1) Type of light do the telescopes see :
Hubble : Hubble’s main focus is on visible and ultraviolet light. Its instruments can observe a small portion of the infrared spectrum from 0.8 to 2.5 microns, but not to the extent that James Webb can. Instead it focuses its unique ultraviolet (0.1 to 0.4 micron) capabilities.
Webb space: James Webb has been designed to focus on the infrared part of the spectrum from 0.6 (red light) to 28 microns (infrared). This means it won’t be able to see in ultraviolet light like Hubble, but will be able to focus on infrared bright objects like extremely distant galaxies.
2) Size:
Hubble : Hubble is 13.2 meters (43.5 ft.) long and its maximum diameter is 4.2 meters (14 ft.) It is about the size of a large tractor-trailer truck.
Webb space : James Webb\'s sunshield is about 22 meters by 12 meters (69.5 ft x 46.5 ft). It\'s about half as big as a 737 aircraft. The sunshield is about the size of a tennis court.
3) distances between the telescopes and Earth
Hubble : The Hubble Space Telescope orbits around the Earth at an altitude of ~570 km above it.
Webb space: James Webb will not actually orbit the Earth - instead it will sit at the Earth-Sun L2 Lagrange point, 1.5 million km away! At the L2 point James Webb\'s solar shield will block the light from the Sun, Earth, and Moon. This will help James Webb stay cool, which is very important for an infrared telescope.
I hope this would be helpful ...

1-What are the consequences of long term unemployment- 2-Should the go.docxtodd991
1.What are the consequences of long term unemployment?
2.Should the government help the unemployed? What role do you think the government has in our economy?
3.What should individuals facing long term unemployment do to deal with this situation?
Solution
1) the rise in the incidence of longterm unemployment has been \"caused\" by a collapse of outflow rates at all durations of unemployment; while the longterm unemployed do leave unemployment at a slower rate than the shortterm unemployed, this has always been the case and their relative outflow rate has not fallen over time; there is no evidence that, for a given level of unemployment, the incidence of longterm unemployment has been ratcheting up over time; once one controls for heterogeneity of the unemployed, there is little evidence of outflow rates that decline over a spell of unemployment. While these findings suggest that longterm unemployment is not a problem independent of unemployment itself, one should recognize that the experience of longterm unemployment is a horrid one for those unfortunate enough to experience it
2) the Great Depression of the 1930s, recessions -- periods of slow economic growth and highunemployment -- were viewed as the greatest of economic threats. When the danger of recession appeared most serious, government sought to strengthen theeconomy by spending heavily itself or cuttingtaxes so that consumers would spend more, and by fostering rapid growth in the money supply, which also encouraged more spending. In the 1970s, major price increases, particularly for energy, created a strong fear of inflation -- increases in the overall level of prices. As a result, government leaders came to concentrate more on controlling inflation than on combating recession by limiting spending, resisting tax cuts, and reining in growth in the money supply.
Ideas about the best tools for stabilizing theeconomy changed substantially between the 1960s and the 1990s. In the 1960s, government had great faith in fiscal policy -- manipulation of government revenues to influence the economy. Since spending andtaxes are controlled by the president and the Congress, these elected officials played a leading role in directing the economy

2. What are ways that gender can shape sociological research?
3. Do you think Zimbardo’s Stanford County Prison (research it) experiment was ethical, or should he have been prevented from conducting this study? Defend your position.
4.Explain how you would develop a representative sample of students on your campus in order to conduct some survey research.
Solution
Such research involves a range of well-defined, though variable methods: informal interviews, direct observation, participation in the life of the group, collective discussions, analyses of personal documents produced within the group, self-analysis, results from activities undertaken off or online, and life-histories. Although the method is generally characterized as qualitative research, it can (and often does) include quantitative dimensions. Traditional participant observation is usually undertaken over an extended period of time, ranging from several months to many years, and even generations. An extended research time period means that the researcher is able to obtain more detailed and accurate information about the individuals, community, and/or population under study. Observable details (like daily time allotment) and more hidden details (like taboo behavior) are more easily observed and interpreted over a longer period of time. A strength of observation and interaction over extended periods of time is that researchers can discover discrepancies between what participants say—and often believe—should happen (the formal system) and what actually does happen, or between different aspects of the formal system; in contrast, a one-time survey of people\'s answers to a set of questions might be quite consistent, but is less likely to show conflicts between different aspects of the social system or between conscious representations and behavior.
In participant observation,a researcher\'s discipline based interests and commitments shape which events he or she considers are important and relevant to the research inquiry.According to Howell (1972), the four stages that most participant observation research studies are establishing rapport or getting to know the people, immersing oneself in the field, recording data and observations, and consolidating the information gathered.

Delta Sigma Theta (???) is a not-for profit Greek-lettered sorority of college-educated women dedicated to public service with an emphasis on programs that target the African American community. Delta Sigma Theta Sorority was founded on January 13, 1913, by 22 collegiate women at Howard University. These students wanted to use their collective strength to promote academic excellence and to provide assistance to persons in need. The first public act of Delta Sigma Theta was the Women\'s Suffrage March in Washington D.C., March 3, 1913. Today, Delta Sigma Theta Sorority is the largest African-American Greek-lettered organization.[2] Membership in Delta Sigma Theta is open to any woman who meets the membership requirements, regardless of religion, race, or nationality. Women may join through undergraduate chapters at a college or university, or after acquiring a college degree through an alumnae chapter.
Since its founding, Delta Sigma Theta has been at the forefront of creating programming to improve political, education, and social and economic conditions. Delta Sigma Theta has been pivotal in assisting the African American and International communities through education, lobbying, and economic initiatives, including Delta Days at the State and Nation\'s Capitol, Delta Days at the United Nations, Summits and various conferences which focus on pertinent issues of the day. In addition to establishing independent programming, The Sorority consistently collaborates with community and corporate organizations Such as Chase (bank), Habitat for Humanity, Coca-Cola, Wal-Mart, Lawry\'s, and General Electric to further its programming goals.
A sisterhood of more than 300,000 initiated members who are predominantly black college-educated women, the sorority currently has over 1,000 chapters located in the United States, England, Japan (Tokyo and Okinawa), Germany, the Virgin Islands, Jamaica, Bermuda, the Bahamas and the Republic of Korea. Delta Sigma Theta is a member of multiple organizations, including the National Pan-Hellenic Council (NPHC)

1-Astronomers estimate that a low-mass red dwarf star like Proxima Cen.docxtodd991
1.Astronomers estimate that a low-mass red dwarf star like Proxima Centauri will shine on the main sequence for four trillion years. Speculate why this star would last so much longer than the estimated 600 Gyr.
2.The star Mira is 1.2 times the mass of the Sun and about 10,000 times more luminous than the Sun. Would Mira fit into the table above? Why or why not?
Solution
1. To understand why red dwarfs have such long lifespans, we’ll need to take a look at main sequence stars first, and see how they’re different. If you could peel back the Sun like a grapefruit, you’d see juicy layers inside.
In the core, immense pressure and temperature from the mass of all that starstuff bears down and fuses atoms of hydrogen into helium, releasing gamma radiation.
Outside the core is the radiative zone, not hot enough for fusion. Instead, photons of energy generated in the core are emitted and absorbed countless times, taking a random journey to the outermost layer of the star.
And outside the radiative zone is the convective zone, where superheated globs of hot plasma float up to the surface, where they release their heat into space.
Then they cool down enough to sink back through the Sun and pick up more heat. Over time, helium builds up in the core. Eventually, this core runs out of hydrogen and it dies. Even though the core is only a fraction of the total mass of hydrogen in the Sun, there’s no mechanism to mix it in.
A red dwarf is fundamentally different than a main sequence star like the Sun. Because it has less mass, it has a core, and a convective zone, but no radiative zone. This makes all the difference.
The convective zone connects directly to the core of the red dwarf, the helium byproduct created by fusion is spread throughout the star. This convection brings fresh hydrogen into the core of the star where it can continue the fusion process.
By perfectly using all its hydrogen, the lowest mass red dwarf could sip away at its hydrogen fuel for 10 trillion years.
2. No , Mira does not fit in that because of high mass.

1.a Which of TCP or UDP is connection-less? Which of TCP or UDP is connection-oriented? What is the difference?
b. Name the four components of a process
c.. What is the PCB?
Solution
1.
a.
UDP is connection-less
TCP is connection oriented
TCP is connection oriented – once a connection is established, data can be sent bidirectional.
UDP is a simpler, connectionless Internet protocol.
Multiple messages are sent as packets in chunks using UDP.
TCP rearranges data packets in the order specified.
UDP has no inherent order as all packets are independent of each other. If ordering is required, it has to be managed by the application layer.
The speed for TCP is slower than UDP.
UDP is faster because there is no error-checking for packets.
There is absolute guarantee that the data transferred remains intact and arrives in the same order in which it was sent.
There is no guarantee that the messages or packets sent would reach at all.
b.
Components of process are following.
1. Object Program
Code to be executed.
2. Data
Data to be used for executing the program.
3. Resources
While executing the program, it may require some resources.
4. Status
Verifies the status of the process execution.A process can run to completion only when all requested resources have been allocated to the process. Two or more processes could be executing the same program, each using their own data and resources.
c.
Process Control Block (PCB, also called Task Controlling Block, process table, Task Struct, or Switchframe) is a data structure in the operating system kernel containing the information needed to manage a particular process. The PCB is \"the manifestation of a process in an operating system\".

1- You align 2 lenses together with known focal lengths fi and fa- The.docxtodd991
1. You align 2 lenses together with known focal lengths fi and fa. The equation to deter- mine the equivalent focal length fq is: D.???. ointaining the distance
Solution
Option (D) 1/f(eq) = 1/f1 + 1/f2, is the correct answer.
Explanation -
To prove the relation, we consider two thin convex lenses L1 and L2 in contact. Let the foci of the two lenses be f1 and f2 respectively. A point object O is placed. We assume a ray of light from O passing through the first lens L1. It forms an image at I1, in the absence of L2. Then we consider the image formation for the second lens. For the second lens the object is I1. I1 acts as a virtual object fro L2 and the image is formed at I.
Let:
u = object distance
v = distance of image I
v1 = distance of image I1
Using lens formula, we know that
1/f = 1/v + 1/u ------------------------------(i)
Let us consider each lens separately:
Applying sign convention
For L1:-
f = +f1
v = +v1
u = - u
Now substituting them in equation (i), we get:
1/f1 = 1/ (+v1) + 1/ (-u)
1/f1 = 1/v1 -1/u -----------------------? (ii)
For L2:-
f = +f2
v = +v
u = -v1
Now substituting the above in equation (i) we get:
1/f2 = 1/ (v) + 1/ (- v1)
1/f2 = 1/ (v) - 1/ (v1) ------------------------? (iii)
Adding the equation (ii) and (iii):
1/f1 +1/f2 = [1/v1 -1/u] + [1/ (v) - 1/ (v1)]
1/f1 +1/f2 = 1/(v1) -1/(u) + 1/ (v) - 1/ (v1)
1/f1 +1/f2 = -1/u + 1/ (v)
1/f1 +1/f2 = 1/v -1/u ------------------------? (iv)
Now, if the focal length of the combination of the two lenses L1 and L2 is F and the real image is formed at I (at v distance from the lens) and the object being at O (at distance u from the lens), then:
1/F = 1/v + 1/ (-u)
1/F = 1/v -1/u ----------------------? (v)
From (iv) and (v), we get:
1/F = 1/f1 + 1/f2
means -
1 / f(eq) = 1/f1 + 1/f2.
This is the relation we have mentioned above.

Solution
MALTHUS, THOMAS ROBERT
( b . near Guildford, Surrey, England, 13 February 1766; d . near Bath, England, 23 December 1834, political economy .
Malthus is known in the history of science almost exclusively for his influence on Charles Darwin, exerted almost accidentally. His life, work, and friends were mainly centered on social conditions and political economy, and his work on population was part of these. He did have early training in mathematics, however, and based his arguments on the careful analysis of observed data.
Robert Malthus (he appears never to have been called Thomas) was the sixth child of seven born to Daniel Malthus and his wife, the former Henrietta Catherine Graham. Daniel Malthus, a scholar and a friend and admirer of Rousseau, provided a stimulating home life and education for the boy, and later sent him to study with Richard Graves at Claverton and at the Dissenting Academy of Warrington under Gilbert Wakefield.
In 1784 Malthus went up to Jesus College, Cambridge, where his tutor was William Frend. He read for the mathematical tripos and graduated in 1788, being ninth wrangler; but he also read widely in French and English history and literature and in Newtonian physics. He had already shown his interest in the practical rather than the abstract. He played games and lived a full social life, apparently unaffected by his cleft palate and harelip. The friends he made at Cambridge influenced the rest of his life; the most important was William Otter (1768

How does each position offer a critique of the others? 2. The text discusses how sociologists operationalize the concept of social class. How would you operationalize important concepts such as intelligence, aggressiveness, femininity, or level of commitment to religion? 3. Discuss the links between the three methodological approaches to sociology and the three theoretical approaches? 4. Suppose you are a sociologist studying alleged police brutality. Construct two arguments, one proposing that you ought to be as objective as possible in your work and let others use your results as they may choose, and the other suggesting that, while striving for accuracy, you should take a stand against any injustices which your research may uncover. Which position do you find more convincing? Why? 5. What are ways that gender can shape sociological research? 6. To a young researcher, what are the advantages of using the method of participant observation? What are the disadvantages? 7.

Solution
1. What are the advantages and disadvantages of each of sociology’s main approaches to doing research: scientific sociology, interpretative sociology, and critical sociology? How does each position offer a critique of the others?
Now we are going to explain about
the above sociology are going to be explaining briefly
scientific sociology : Sociologists of scientific knowledge study the development of a Scientific field and attempt to identify points of contingency or interpretative flexibility where ambiguities are present.
Interpretative sociology : Another way to look at society is to ask how people interpret the world around them    and react to those interpretations.Interpretivist sociology looks at the way society is shaped by the interpretations of the world.
Critical sociology : in sociology critical sociology is about critical thinking is often presented as a generic technique.
Critical thinking movement has spawned on industry of product lines , analytical typologies and multi-stage models.Critical thinking has been touched as promoting higher order thinking.

1. What are the three fundamental elements of an effective security program for information systems? 2. Of these three fundamental controls, which two are used by the Domain User Admin to create users and assign rights to resources? 3. If you can browse a file on a Windows network share, but are not able to copy it or modify it, what types of access controls and permissions are probably configured? 4. What is the mechanism on a Windows server that lets you administer granular policies and permissions on a Windows network using role based access? 5. What is two-factor authentication, and why is it an effective access control technique? 6. Relate how Windows Server 2012 Active Directory and the configuration of access controls achieve C-I-A for departmental LANs, departmental folders, and data. 7. Is it a good practice to include the account or username in the password? Why or why not?
Solution
Answer:
1. Identification, Authentication, and Authorization are the three fundamental elements of an effective security program for information systems.
2.Authentication and Authorization are the two elements, used by the Domain User Admin to create users and assign rights to resources.
3. read and write permissions should be properly configured. The file access type should be set to read only.
4. Group Policy Editor is used to administer granular policies and
permissions on a Windows network using role-based access.
5. The two-factor authentication is a process, requires two different type of identification, such as an ID card and a pin code / password. The user must authenticate with two forms of ID to prove thier identity. So it is effective.
6.In Windows Server 2008 R2, permissions can be set for files and folders.o grant a user, access only to files owned by him and prevent him from accessing any others.
7.Including the account or username in the password is absolutely not a good or suggested practice. It is a common starting place for hackers when attempting to log in to someone’s account or when trying to use another person’s access.

1- What are the various theories that we use to explain why people com.docxtodd991
1. What are the various theories that we use to explain why people commit crimes? How are they broadly categorized?
Solution
In criminology, examining why people commit crime is very important in the ongoing debate of how crime should be handled and prevented. Many theories have emerged over the years, and they continue to be explored, individually and in combination, as criminologists seek the best solutions in ultimately reducing types and levels of crime. Here is a broad overview of some key theories:
Rational choice theory: People generally act in their self-interest and make decisions to commit crime after weighing the potential risks (including getting caught and punished) against the rewards.
Social disorganization theory: A person’s physical and social environments are primarily responsible for the behavioral choices that person makes. In particular, a neighborhood that has fraying social structures is more likely to have high crime rates. Such a neighborhood may have poor schools, vacant and vandalized buildings, high unemployment, and a mix of commercial and residential property.
Strain theory: Most people have similar aspirations, but they don’t all have the same opportunities or abilities. When people fail to achieve society’s expectations through approved means such as hard work and delayed gratification, they may attempt to achieve success through crime.
Social learning theory: People develop motivation to commit crime and the skills to commit crime through the people they associate with.
Social control theory: Most people would commit crime if not for the controls that society places on individuals through institutions such as schools, workplaces, churches, and families.
Labeling theory: People in power decide what acts are crimes, and the act of labeling someone a criminal is what makes him a criminal. Once a person is labeled a criminal, society takes away his opportunities, which may ultimately lead to more criminal behavior.
Biology, genetics, and evolution: Poor diet, mental illness, bad brain chemistry, and even evolutionary rewards for aggressive criminal conduct have been proposed as explanations for crime.

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.

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
