Immigration, Public Opinion and Congress

The bipartisan, bicameral congressional committee has announced a tentative spending agreement that, if passed by both the House and Senate and signed by President Donald Trump by Friday, will avert a second partial government shutdown.

The committee of 17 senators and other members of Congress no doubt considered many factors during their deliberations. These lawmakers were elected to represent the people of their states and districts, so the views of some of the people of this country were represented in their deliberations, if only indirectly. But how well does what the committee came up with reflect broad American public opinion?

I generally group immigration into three buckets: 1) dealing with the inflow of undocumented immigrants, 2) dealing with immigrants already living in the country illegally, and 3) deciding how many immigrants should be admitted into the country legally. It turns out that the congressional committee focused intently on at least two of these areas in its discussions.

Public Opinion and Border Security

Border security is the aspect of immigration that has received the most attention and that ultimately was at the bottom of the last shutdown.

The big question confronting the committee, of course, was just how best to secure the border.

The proposed solution that has received the most attention is the idea of expanding the wall along the U.S.-Mexico border. The wall has become a symbolic issue that was, in many ways, at the bottom of the 2018-2019 government shutdown. (Worth noting -- the U.S. border with Canada is much longer than the border with Mexico, but it is the latter that has received most of the attention.)

The bipartisan committee apparently has agreed to spend about $1.4 billion for "barriers" or "fences" (as news reports have described it). It's possible that public opinion may be more welcoming to those softer descriptions rather than the emotionally charged "wall." For example, a Harvard Harris poll found that 54% of Americans support "building a combination of physical and electronic barriers across the U.S.-Mexico border."

Bottom line: The agreement to cut the allocation for a border barrier down to a relatively small $1.4 billion fits with the prevailing public sentiment, although it appears that many Americans would be OK with no wall money at all.

(At this point, it's unclear if the agreement specifically references other ways in which border security could be enhanced. Gallup recently asked about hiring more border patrol agents and found that three-quarters support the idea. I assume there would be similarly high levels of support for acquiring more electronic and technical capabilities to help stop the inflow of illegal immigration. But I haven't seen polling supporting that idea.)

Dealing With Immigrants Living in the U.S. Illegally

The bipartisan committee focused on more than just the wall. News reports indicate that a major committee disagreement centered on the challenge of dealing with people already living in this country illegally. This included the apparently tricky sticking point of the number of "detention beds" to be included as part of the agreement. This number of detention beds is directly related to the number of illegal immigrants who can be arrested and detained.

I am not aware of any current public opinion polling on detention beds. This is one of those issues on which the average American, and most likely the average elected official, doesn't have a great deal of precise knowledge. More generally, however, we know that about six in 10 Americans oppose the idea of deporting "all immigrants who are living in the United States illegally." I don't think anyone on the committee was proposing that type of massive effort. But obviously discussions of proposals to deport some illegal immigrants were highly contentious.

Americans' opposition to the idea of deporting illegal immigrants likely stems from the fact -- confirmed in many measures of public opinion over the years -- that Americans support the idea of finding a pathway to citizenship for those living in the country illegally.

A few years ago, Gallup found a slightly higher priority given to the idea of dealing with immigrants living in the U.S. illegally than to the idea of halting the flow of immigrants coming into the country illegally. Most recently, Gallup's update shows that over eight in 10 Americans favor allowing undocumented immigrants "the chance to become U.S. citizens if they meet certain requirements over a period of time." Quinnipiac polling last year showed that two-thirds agreed that illegal immigrants currently living in the U.S. "should be allowed to stay in the United States and to eventually apply for U.S. citizenship." That's as opposed to the other two options offered -- allowing them to stay but not apply for U.S. citizenship, or requiring them to leave.

The polls also show overwhelming support for allowing those who were brought here illegally as children to remain in the U.S. Almost eight in 10 Americans in the same Quinnipiac poll last year supported the idea of "allowing undocumented immigrants who were brought to the U.S. as children to remain in the United States and eventually apply for citizenship."

The American public, it appears, is most likely in favor of a mixed approach to immigrants living in the country illegally. That would include some effort to deport illegal immigrants (presumably in particular those who break laws and commit crimes), with a bigger effort to develop a pathway to citizenship for those living here illegally. Apparently, the congressional committee was also in favor of a mixed approach, but had trouble deciding on exactly what that mix should be.

Unanswered Questions on Legal Immigration

The bipartisan committee didn't get around to addressing legal immigration per se. If it had, public guidance would have been less clear-cut. The data show very mixed views from the American people about whether legal immigration should be expanded, reduced or kept the same.

Trump surprised some listeners in his State of the Union address when he said, "I want people to come into our country in the largest numbers ever, but they have to come in legally."

As Gallup's Jim Clifton recently reviewed, there is tremendous interest among Latin American countries in migrating to the United States. This presents both opportunities and challenges for policymakers, depending on what value America chooses to place on immigration.

Americans agree in principle that immigration is a good thing for America -- more than at any time in Gallup's history of asking the question. Previous Gallup research has also shown that Americans in general say immigration is good for the economy, that immigrants don't take jobs away from Americans and that immigrants don't affect wage levels.

But there is no apparent groundswell of interest for increasing the level of immigration. Our latest Gallup update showed that 30% of Americans say they want immigration increased. This comes in response to a three-part question that also allows Americans to say immigration should be kept as it is (37% choose this alternative) or decreased (31%).

As Congress and the president consider the bipartisan committee's recommendations, they need to keep in mind that Americans overwhelmingly favor protecting the border, although with skepticism about the need for new border walls. Americans also overwhelmingly favor approaches for allowing undocumented immigrants already living in the U.S. to stay here. And, while recognizing that immigration is good for the country, Americans have mixed views about changing the level of legal immigration.

Lesson: Immigration, Public Opinion and Congress

Introduction:
Immigration is a complex issue that affects many aspects of society. In this lesson, we will explore how immigration policy is formed and how it reflects the opinions of the American public. We will also examine the role of Congress in shaping immigration policy.

Section 1: Understanding Immigration Policy

Topic 1: Dealing with the Inflow of Undocumented Immigrants

Question: What is the current policy on dealing with undocumented immigrants?
Answer: The current policy is to detain and deport undocumented immigrants who are caught entering or remaining in the country illegally.

Topic 2: Dealing with Immigrants Already Living in the Country Illegally

Question: What is the current policy on dealing with immigrants who are already living in the country illegally?
Answer: The current policy is to prioritize the deportation of immigrants who have committed serious crimes. However, the policy also includes measures to detain and deport immigrants who have been in the country illegally for a certain period.

Topic 3: Deciding How Many Immigrants Should Be Admitted into the Country Legally

Question: What is the current policy on deciding how many immigrants should be admitted into the country legally?
Answer: The current policy is to admit a certain number of immigrants based on family ties, employment offers, and refugee status.

Section 2: Public Opinion on Immigration

Topic 1: How do Americans feel about immigration?
Answer: There is no single answer to this question as opinions on immigration vary greatly depending on the individual's background, political affiliation, and geographic location. However, polls have shown that a majority of Americans support legal immigration and oppose the deportation of immigrants who were brought to the country as children.

Topic 2: How do Americans feel about undocumented immigrants?
Answer: Again, there is no single answer to this question. Some Americans believe that undocumented immigrants should be allowed to stay in the country, while others believe they should be deported.

Section 3: The Role of Congress in Shaping Immigration Policy

Topic 1: How does Congress play a role in shaping immigration policy?
Answer: Congress plays a significant role in shaping immigration policy. It has the power to create and change immigration laws through legislation. The executive branch, led by the president, is responsible for enforcing these laws.

Topic 2: How does public opinion influence Congress's approach to immigration policy?
Answer: Public opinion can influence Congress's approach to immigration policy, especially in an election year. Politicians may try to appeal to voters by taking positions on immigration issues that align with public opinion.

Conclusion:
In conclusion, immigration policy is a complex issue that involves dealing with the inflow of undocumented immigrants, immigrants already living in the country illegally, and deciding how many immigrants should be admitted into the country legally. The opinions of the American public play a role in shaping immigration policy, and Congress has a significant role in shaping these policies. By understanding the different aspects of immigration policy and how they reflect public opinion, we can better understand the challenges facing our country and work towards finding solutions that benefit all.

Good morning, and welcome to our witnesses. I look forward to your testimony.

As my colleagues know, I am a strong supporter of NASA, both its science programs and its human spaceflight activities. I also am keenly interested in and excited by the entrepreneurial energy being devoted to human spaceflight these days. The passion of those working on commercial approaches to human spaceflight is infectious--and as I've said before, I'd love to fly into space myself someday!

That said, in my capacity as a Member of this oversight Committee, I have a responsibility to scrutinize each of NASA's major projects to make sure that they are well planned and executable. NASA's commercial crew program has to be subjected to that same level of oversight if we are doing our jobs on this Committee.

In that regard, I have to say that I am concerned that NASA is not holding that program to the same standard as its other major acquisitions. And make no mistake--this is a major acquisition for NASA. When the taxpayer is paying on average 9 out of every 10 dollars being spent to develop these commercial crew vehicles, we are not talking about a straightforward purchase of commercial services from the GSA list--these services don't even exist yet.

That said, I am puzzled and a bit frustrated that NASA appears to be unable or unwilling to acknowledge the warning signs that this major program is not on a firm path to success at present. In that regard, the written testimony of the Chair of the Aerospace Advisory Panel (ASAP), Admiral Dyer, is illuminating. While his prose is cautious and understated, it is hard not to read the concern couched in such statements as:

"Lacking an independent cost estimate, we are uncertain as to affordability." "However, we arrive at this point in time with designs that are maturing before requirements, and where government and industry have not yet agreed on how winning designs will be accepted and certified. We worry that the cart is ahead of the horse", and "NASA is just now undertaking to determine how systems will be certified to transport NASA astronauts. This timing increases programmatic risk and has serious potential to impact safety."

To that I would add some of my own concerns, namely that not only do we not have an independent cost assessment to guide our congressional deliberations, we don't have any independent assessment of when these commercial systems will actually be able to start operational service to the International Space Station. NASA is saying "in the 2017 timeframe" in Mr. Gerstenmaier's testimony and even 2018 in one of its notional planning charts--and I would note that both of those dates are within just a few years of the currently scheduled end of Space Station operations--and years later thanoriginally promised. Moreover, both of those dates appear to be based on assumed funding levels for the commercial crew program that don't seem to bear much resemblance to what Congress has authorized or appropriated so far, or is likely to approve in the foreseeable future. If that's true, then I think we need NASA to give us a cost and schedule estimate that is based on more realistic budgetary assumptions, so we can see what is most likely to actually happen--something we require for all of NASA's other major programs.

In addition, NASA still has not given Congress a clear understanding of how much it will cost to fly our astronauts on these commercial systems. It is reported that NASA has had independent assessments that estimate that NASA's commercial crew seat costs are likely to be several times as high as Soyuz costs. Is that true? We need to know.

And finally, as alluded to in Admiral Dyer's testimony, NASA's latest approach to acquiring these commercial crew systems is, to put it charitably, "complex and unique". Trying to run Space Act Agreements in parallel to FAR-based contracts may be a "workaround", as the ASAP testimony phrases it, but that begs the question of why NASA didn't just stick to its original plan for FAR-based contracting.

Well, we have much to talk about today. As I close though, I would like to say that I deeply appreciate the service rendered to this Committee and to the nation on a continuing basis by the two gentlemen appearing before us today. You both have very hard jobs, and we appreciate your efforts. Thank you, and with that I yield back the balance of my time.

Lesson: Introduction to Rocket Science

### Section 1: What is Rocket Science?
Rocket science is the study of how rockets work and how they can be used to explore space. Rockets are machines that use fuel to propel themselves into the air, and they can carry people and equipment into space.

### Section 2: Why Study Rocket Science?
Studying rocket science can help us understand how rockets work, how they can be used to explore space, and how we can design and build better rockets in the future. It can also help us learn about the science of aerodynamics, propulsion, and materials engineering.

### Section 3: How Do Rockets Work?
Rockets work by burning fuel to create thrust. The fuel is usually a liquid, such as hydrogen or kerosene, and it is stored in a tank in the rocket. When the rocket engine is turned on, the fuel is pumped into the combustion chamber, where it is mixed with air and ignited. This creates a fireball that pushes the rocket forward.

### Section 4: Types of Rockets
There are two main types of rockets: solid fuel rockets and liquid fuel rockets. Solid fuel rockets use a solid fuel that is packed into the rocket and ignited all at once. Liquid fuel rockets use a liquid fuel that is pumped into the rocket engine and ignited.

### Section 5: Applications of Rocket Science
Rocket science has many applications, including launching satellites into orbit, sending people into space, and exploring other planets. It is also used in the development of military technology, such as missiles and rockets.

### Section 6: Conclusion
Rocket science is an exciting field that has many practical applications. By studying rocket science, we can learn how to design and build better rockets, explore space, and improve our understanding of the universe.


text: Keywords: [ Monte Carlo Methods ] [ Probabilistic Methods ]. High-dimensional partial differential equations (PDEs) are ubiquitous in economics, science and engineering. However, their numerical treatment poses formidable challenges since traditional grid-based methods tend to be frustrated by the curse of dimensionality. In this paper, we argue that tensor trains provide an appealing approximation framework for parabolic PDEs: the combination of reformulations in terms of backward stochastic differential equations and regression-type methods in the tensor format holds the promise of leveraging latent low-rank structures enabling both compression and efficient computation. Following this paradigm, we develop novel iterative schemes, involving either explicit and fast or implicit and accurate updates. We demonstrate in a number of examples that our methods achieve a favorable trade-off between accuracy and computational efficiency in comparison with state-of-the-art neural network based approaches.

Lesson: Introduction to Monte Carlo Methods and Probabilistic Methods

### Section 1: Introduction
In this lesson, we will learn about Monte Carlo Methods and Probabilistic Methods. These methods are used to solve problems that involve uncertainty or randomness. We will cover the basics of these methods and how they can be applied in various fields such as economics, science, and engineering.

### Section 2: Monte Carlo Methods
Monte Carlo Methods are a class of computational algorithms that rely on random sampling and statistical inference to obtain numerical results. These methods are particularly useful when it is difficult or impossible to find an exact analytical solution to a problem.

One of the most common applications of Monte Carlo Methods is in simulating the behavior of complex systems or processes. For example, physicists use Monte Carlo Methods to study the behavior of particles in high-energy physics experiments. Financial analysts use these methods to model the behavior of stock prices and other financial instruments.

To perform a Monte Carlo simulation, you first need to define the problem you want to solve. This typically involves specifying the inputs and outputs of the system you are studying, as well as any constraints or assumptions that apply. Next, you generate a large number of random samples that represent possible outcomes of the system. You then analyze these samples to infer properties of the system, such as its mean or variance.

There are many variations of Monte Carlo Methods, each designed to address specific types of problems. Some common variations include:

- Discrete Monte Carlo: This method involves generating random samples of the system's state space and evaluating the system's behavior at each sample.
- Continuous Monte Carlo: This method involves generating random samples of the system's continuous state space, typically using random numbers generated by a computer.
- Monte Carlo Tree Search: This method involves constructing a tree of all possible outcomes of the system, then randomly sampling nodes in the tree to evaluate the system's behavior.

### Section 3: Probabilistic Methods
Probabilistic Methods are a class of mathematical techniques that involve the use of probability theory to model and analyze systems or processes. These methods are particularly useful when it is difficult or impossible to find an exact analytical solution to a problem.

One of the most common applications of Probabilistic Methods is in modeling the behavior of complex systems or processes. For example, statisticians use Probabilistic Methods to model the behavior of populations and make predictions about future events. Engineers use these methods to design and optimize systems and processes.

To perform a probabilistic analysis, you first need to define the problem you want to solve. This typically involves specifying the inputs and outputs of the system you are studying, as well as any constraints or assumptions that apply. Next, you use probability theory to model the behavior of the system, typically by defining probability distributions that represent the possible outcomes of the system. You then analyze these distributions to infer properties of the system, such as its mean or variance.

There are many variations of Probabilistic Methods, each designed to address specific types of problems. Some common variations include:

- Bayesian Analysis: This method involves using Bayes' theorem to update your beliefs about the system's behavior based on new evidence.
- Monte Carlo Simulation: This method involves generating random samples of the system's state space and analyzing these samples to infer properties of the system.
- Stochastic Optimization: This method involves finding the optimal solution to a problem while accounting for uncertainty or randomness.

### Glossary
- Monte Carlo Methods: A class of computational algorithms that rely on random sampling and statistical inference to obtain numerical results.
- Probabilistic Methods: A class of mathematical techniques that involve the use of probability theory to model and analyze systems or processes.
- Random Sampling: The process of generating a large number of random samples to represent possible outcomes of a system.
- Statistical Inference: The process of using data to make inferences about the behavior of a system or process.
- Probability Distributions: Functions that describe the possible outcomes of a system or process, and the likelihood of each outcome occurring.

### Conclusion
In this lesson, we learned about Monte Carlo Methods and Probabilistic Methods, two powerful techniques for solving problems that involve uncertainty or randomness. We covered the basics of these methods and how they can be applied in various fields. By understanding the principles behind these methods, we can apply them to new problems and gain valuable insights into complex systems and processes.

"On the Feasibility of Side-Channel Attacks with Brain-Computer Interfaces," a paper presented by UC Berkeley and U Geneva researchers at this summer's Usenix Security, explored the possibility of adversarial mind-reading attacks on gamers and other people using brain-computer interfaces, such as the Emotiv games controller.

The experimenters wanted to know if they could forcefully extract information from your brain by taking control of your system. In the experiment, they flashed images of random numbers and used the automatic brain-response to them to make guesses as which digits were in their subjects' ATM PINs. Another variant was watching the brain activity of subjects while flashing the logo of a bank and making a guess about whether the subject used that bank.

I suppose that over time, an attacker who was able to control the stimulus and measure the response could glean a large amount of private information from a victim, without the victim ever knowing it.

Brain computer interfaces (BCI) are becoming increasingly popular in the gaming and entertainment industries. Consumer-grade BCI devices are available for a few hundred dollars and are used in a variety of applications, such as video games, hands-free keyboards, or as an assistant in relaxation training. There are application stores similar to the ones used for smart phones, where application developers have access to an API to collect data from the BCI devices. The security risks involved in using consumer-grade BCI devices have never been studied and the impact of malicious software with access to the device is unexplored. We take a first step in studying the security implications of such devices and demonstrate that this upcoming technology could be turned against users to reveal their private and secret information. We use inexpensive electroencephalography (EEG) based BCI devices to test the feasibility of simple, yet effective, attacks. The captured EEG signal could reveal the user's private informa- tion about, e.g., bank cards, PIN numbers, area of living, the knowledge of the known persons. This is the first attempt to study the security implications of consumer-grade BCI devices. We show that the entropy of the private information is decreased on the average by approximately 15 % – 40 % compared to random guessing attacks.

Lesson Title: Understanding Brain-Computer Interfaces and their Risks

Introduction:
In this lesson, we will learn about Brain-Computer Interfaces (BCI) and their potential risks. We will explore how BCI works, its applications, and the dangers associated with it. By the end of this lesson, you will be able to understand the importance of BCI and its implications on personal privacy and security.

Section 1: What is a Brain-Computer Interface?

A Brain-Computer Interface (BCI) is a technology that allows computers to communicate with the human brain. It translates thoughts into action, enabling individuals to control devices with their minds. BCI can be used in various applications, including gaming, healthcare, and virtual reality.

Section 2: How does BCI work?

BCI works by recording brain activity using electroencephalogram (EEG) sensors. These sensors detect electrical signals produced by neurons in the brain when a person thinks or moves. The recorded signals are then translated into digital commands that control devices or software applications.

Section 3: Applications of BCI

BCI has several applications, including:

1. Gaming: BCI enables gamers to control characters and objects in games using their thoughts.
2. Healthcare: BCI can help individuals with disabilities regain control over their bodies and communicate with others.
3. Virtual Reality: BCI can enhance the immersion experience in virtual reality by allowing users to control their environment using their thoughts.
4. Education: BCI can improve learning by helping students focus on specific tasks or information.

Section 4: Risks of BCI

While BCI has several benefits, it also comes with risks, including:

1. Privacy: BCI can expose individuals' private thoughts and actions to third parties.
2. Security: BCI can be vulnerable to hacking, leading to unauthorized access and control of devices or software applications.
3. Manipulation: BCI can be used to manipulate individuals' thoughts and actions, causing harm or damage.

Section 5: Conclusion

In conclusion, BCI is a powerful technology that has the potential to change our lives. However, it also comes with risks that must be addressed. By understanding these risks, we can develop strategies to mitigate them and ensure that BCI is used safely and responsibly.

Glossary:
- Brain-Computer Interface (BCI): A technology that allows computers to communicate with the human brain.
- Electroencephalogram (EEG): A device that records electrical signals produced by neurons in the brain.
- Virtual Reality (VR): A computer-generated environment that simulates physical presence in a real or imagined world.

Self-Debating Discussion:

1. How can we balance the benefits of BCI with the risks associated with it?
2. What measures can be taken to ensure that BCI is used safely and responsibly?
3. Should BCI be regulated, and if so, how?

Conclusion:

In this lesson, we learned about Brain-Computer Interfaces and their potential risks. We explored how BCI works, its applications, and the dangers associated with it. By understanding these risks, we can develop strategies to mitigate them and ensure that BCI is used safely and responsibly. This knowledge can be applied to new problems and situations as BCI technology continues to evolve.

Lesson: How Ants Lift Objects

Introduction:
Ants are amazing creatures that can lift objects much heavier than their own body weight. In this lesson, we will learn about the biomechanics behind their strength and how it can be applied in robotic engineering.

Section 1: The Biomechanics of Ant Strength
1.1 What is biomechanics?
Biomechanics is the study of how living organisms move and use energy. It helps us understand how animals like ants can lift objects much heavier than their own body weight.

1.2 How do ants lift objects?
Ants use their mandibles (mouthparts) to grip the object they want to lift. They then transfer the load through their neck joint to their thorax, which distributes it evenly over their six legs and tarsi (the part of their leg that anchors to the ground).

1.3 Why are researchers interested in ant strength?
Researchers are interested in ant strength because it is one of nature's little mysteries. By understanding how ants can lift objects so efficiently, scientists may be able to apply this knowledge to robotic engineering and create robots that can lift heavy objects as well.

Section 2: The Science Behind Ant Strength
2.1 What is the scientific explanation for ant strength?
The secret behind ant strength lies in their unique body structure and muscle arrangement. Ants have a large number of muscles in their legs, which allows them to generate a lot of force. Additionally, their legs are connected to a rigid exoskeleton, which provides support and stability.

2.2 How does an ant's muscle arrangement work?
Ants have a unique arrangement of muscles in their legs called a "hexagonal" or "radial" muscle arrangement. This means that the muscles are arranged in a hexagonal pattern, which allows for more efficient transfer of force from the muscles to the legs.

2.3 How does an ant's exoskeleton help with strength?
An ant's exoskeleton is made up of chitin, a strong and lightweight material. This provides support and stability while allowing the ant to move quickly and efficiently. The exoskeleton also helps to distribute the weight of the object being lifted evenly across the ant's body.

Section 3: Applying Ant Strength to Robotic Engineering
3.1 How could ant strength be applied to robotic engineering?
By understanding the biomechanics behind ant strength, engineers could potentially design robots that are capable of lifting heavy objects as well. For example, a robot with legs designed like an ant's could potentially lift objects much heavier than its own body weight.

3.2 What challenges would need to be overcome to create such a robot?
One challenge would be creating a material for the robot's exoskeleton that is as strong as chitin but also lightweight. Another challenge would be designing the robot's muscle arrangement to mimic that of an ant's.

Conclusion:
In conclusion, the secrets behind ant strength lie in their unique biomechanics and body structure. By studying these secrets, researchers may be able to apply this knowledge to robotic engineering and create machines that can lift objects as efficiently as ants.

Q:

Vim project plugin \R not refreshing new directories created

I'm using the vim project plugin to manage a project, and whenever a new file goes in I need to use \R to refresh the project tree. This is fine, but I recently created a new directory in the tree, and \R doesn't update it and put it into the project.
What am I doing wrong?

A:

\R only updates the folds.  The only satisfactory ways I've found to do add new directories is either to remove the entry and re-run \C to create the project again (I only tend to use this if there are a lot of new directories to include) or to add the directory manually like this:
Name=Path {
}

and then hit \r in that fold.
Although I've find this frustrating at times, I tend to consider it a feature now: I have a Documentation directory in my project, which contains all of the doxygen generated files and directories, of which there are masses.  If I use \C after running doxygen, there are a ridiculous number of folds, so I then delete them from the list.  \R then doesn't re-add them, which is a good thing.
It also means I can have (for example) a daft folder structure like this:
Project/
    Source/
        File1.c
        File2.c
    Headers/
        File1.h
        File2.h
    LibraryModules/
        FreeRTOS/
            Source/
                RTOSSource.c
                portable/
                    RVDS/
                        ARM_CM3/
                            port.c

and have it displayed as:
Project=/path/to/Project {
  Source=Source {
    File1.c
    File2.c
  }
  Headers=Headers {
    File1.h
    File2.h
  }
  LibraryModules=LibraryModules {
    FreeRTOSSource=FreeRTOS/Source {
      RTOSSource.c
    }
    FreeRTOSPort=FreeRTOS/Source/portable/RVDS/ARM_CM3 {
      port.c
    }
  }
}

which is at least a BIT more manageable.

# Lesson: Vim Project Plugin and Refreshing New Directories

### Introduction
In this lesson, we will learn about the Vim project plugin and how to use it to manage a project. We will also explore how to refresh the project tree using the `\R` command and how to add new directories to the project.

### Section 1: What is the Vim Project Plugin?
The Vim project plugin is a powerful tool that helps you manage your projects in Vim. It allows you to navigate your project tree easily and efficiently, and it keeps track of your changes.

### Section 2: Refreshing the Project Tree with `\R`
To refresh the project tree using the `\R` command, you need to first set up the project using the `\C` command. Once you have set up the project, you can use the `\R` command to update the project tree. This command will update the folds and show you the changes that have been made to the project.

### Section 3: Adding New Directories to the Project
If you have added a new directory to your project, you need to add it to the project file manually using the following syntax:

```
Name=Path {
}
```

Replace `Name` with the name of the directory and `Path` with the path to the directory. Then, hit the `\r` key in the fold where you want to add the directory.

### Glossary
- Vim: A text editor for command-line users.
- Project: A collection of related tasks or activities.
- Plugin: A software component that adds specific functionality to an existing program.
- Folds: A way to hide code in Vim.
- Doxygen: A tool for generating documentation from comments in code.

### Conclusion
In this lesson, we learned how to use the Vim project plugin to manage our projects. We also learned how to refresh the project tree using the `\R` command and how to add new directories to the project. By understanding these concepts, we can become more efficient in our use of Vim and better manage our projects.

Built in May 1920, hms Hood remained one of the world's largest warships for nearly 20 years, although by the outbreak of WWII she was relatively outdated in terms of naval technology. On May 23rd, 1941, Hood set out as part of a naval force to hunt down Bismarck and Prinz Eugen, which were heading toward the Atlantic to assault Allied shipping. On the morning of the 24th, Hood spotted and engaged the German ships in fierce combat. The more modern Bismarck outmatched Hood, sinking it with hits from its huge main guns. Along with the demoralizing loss of its symbolic flagship, the British navy also suffered the loss of 1,415 men, including Admiral Holland.

A total of 9 E Class Destroyers were built in 1934-35, featuring 1,350 ton displacement, 100m length and top speed of 36 knots. They were armed with 4 main guns, 8 AA guns, 8 torpedo launchers and 20 depth charges. 2 E Class ships, Echo and Electra, escorted Hood on her final mission, both surviving that assignment. Electra had the grim distinction of rescuing Hood's only 3 survivors.

Lesson: Introduction to Naval Combat

### Overview

In this lesson, we will learn about naval combat, specifically focusing on the Battle of the Denmark Strait between the British battleship HMS Hood and the German battleship Bismarck. We will explore the history of these two ships, their weapons, and tactics used during the battle. By the end of this lesson, you will have a better understanding of naval combat and its significance in military history.

### Section 1: Introduction

Naval combat refers to the use of warships to engage and defeat enemy vessels. It has been an essential part of military strategy since ancient times. In this lesson, we will focus on the Battle of the Denmark Strait, which took place during World War II between the British battleship HMS Hood and the German battleship Bismarck.

### Section 2: HMS Hood and Bismarck

HMS Hood was built in 1920 and was one of the largest warships in the world at that time. However, by the outbreak of World War II, it was considered outdated compared to newer naval technology. Bismarck, on the other hand, was a more modern and advanced battleship that Germany had built.

The two ships met on May 24, 1941, in the Atlantic Ocean, where they engaged in fierce combat. The battle lasted for several hours, with both sides sustaining significant damage. Ultimately, Bismarck sank Hood with hits from its main guns, causing the loss of 1,415 men, including Admiral Holland.

### Section 3: Weapons and Tactics

During the Battle of the Denmark Strait, both Hood and Bismarck used various weapons to attack each other. Hood had eight 15-inch guns, while Bismarck had three 15-inch guns and several other smaller guns. The two ships also used different tactics to try and gain an advantage over their opponent.

Hood's strategy was to close in on Bismarck quickly and use its superior speed to engage in close-range combat. Bismarck, on the other hand, used its long-range guns to target Hood from a distance, causing significant damage before closing in for the kill.

### Section 4: Conclusion

The Battle of the Denmark Strait was a significant event in military history, showcasing the importance of naval combat. Although Hood was considered outdated compared to Bismarck, it still managed to engage the more modern ship in fierce combat. The loss of Hood and its crew had a demoralizing effect on the British navy, but it also highlighted the need for continued investment in naval technology.

By studying this battle, we can gain a better understanding of the tactics and weapons used in naval combat. This knowledge can be applied to other military scenarios and can help us appreciate the importance of naval power in both offense and defense.

Lesson Title: Packrafting 101: A Beginner's Guide to Amphibious Adventures

Introduction:
Packrafting is a unique outdoor activity that combines hiking and paddling. It involves carrying a small, portable inflatable raft on your back and using it to navigate rivers, lakes, and other bodies of water. In this lesson, we will explore the basics of packrafting, including gear, safety, and technique.

Section 1: Gear

**Theory:** Packrafting gear includes an inflatable raft, a paddle, a dry bag, and a personal flotation device (PFD). These items are essential for a safe and enjoyable packrafting experience.

**Practice:** Let's discuss each piece of gear in more detail:

1. Inflatable raft: An inflatable raft is a lightweight, portable boat that can be carried on your back. It is made of durable, waterproof material and comes in various sizes and shapes.

2. Paddle: A paddle is a long, narrow oar used to propel the raft through the water. It is typically made of lightweight plastic or carbon fiber and has a blade at one end and a handle at the other.

3. Dry bag: A dry bag is a waterproof container used to store your gear while packrafting. It is designed to keep your belongings dry even if the raft flips over.

4. PFD: A personal flotation device (PFD) is a type of life jacket that helps you stay afloat in the water. It is essential for safety and should always be worn when packrafting.

**Debate:** Which piece of gear do you think is the most important for packrafting? Why?

Section 2: Safety

**Theory:** Safety is a top priority when packrafting. You should always wear a PFD and carry a whistle, compass, and emergency blanket with you.

**Practice:** Let's discuss some safety tips for packrafting:

1. Wear your PFD at all times.
2. Always carry a whistle to signal for help if needed.
3. Know how to use a compass to navigate the terrain.
4. Bring an emergency blanket in case you get cold or wet.
5. Tell someone your planned route before you leave.
6. Check weather forecasts before you go and plan accordingly.

**Debate:** Do you think packrafting is a safe activity? Why or why not?

Section 3: Technique

**Theory:** Packrafting technique involves using your paddle effectively to navigate the water. There are several strokes you can use to move forward, stop, and turn.

**Practice:** Let's learn about the three main paddle strokes:

1. Forward stroke: This stroke is used to move forward. To perform it, place your paddle in the water with the blade facing forward, pull it towards your body, and then push it back out. Repeat on the other side.

2. Stop stroke: This stroke is used to stop or slow down. To perform it, place your paddle in the water with the blade facing backward, pull it towards your body, and then push it back out. Repeat on the other side.

3. Draw stroke: This stroke is used to turn or change direction. To perform it, place your paddle in the water with the blade facing down, pull it towards your body, and then push it out to the side. Repeat on the other side.

**Debate:** Which paddle stroke do you think is the most challenging to master? Why?

Glossary:
- PFD: Personal Flotation Device
- Paddle: A long, narrow oar used to propel the raft through the water
- Dry bag: A waterproof container used to store gear
- Inflatable raft: A lightweight, portable boat made of durable, waterproof material

Conclusion:
Packrafting is an exciting and adventurous outdoor activity that combines hiking and paddling. By following the gear, safety, and technique guidelines provided in this lesson, you can enjoy a safe and fun packrafting experience. Remember to always wear your PFD, carry a whistle and emergency blanket, and use proper paddle strokes to navigate the water.

# Lesson 1: Introduction to Employment Law
## Section 1: Overview of Employment Law
Employment law is a set of rules and regulations that govern the relationship between employers and employees. It covers various aspects of the employment relationship, including hiring, wages, hours, working conditions, and termination. Employment law is designed to protect the rights of employees and ensure that they are treated fairly and equitably in the workplace.
## Section 2: Key Concepts in Employment Law
There are several key concepts in employment law that are important for employers to understand. These include:
- At-will employment: This means that an employee can generally be fired at any time, for any reason or no reason at all, unless the employee has a written contract that states otherwise.
- Wage and hour laws: These laws set minimum wages, maximum hours, and other conditions of employment such as overtime pay, meal breaks, and rest periods.
- Discrimination and harassment: These are prohibited by law and include treating someone unfavorably because of their race, color, religion, sex, national origin, disability, age, or genetic information.
- Workplace safety: Employers must provide a safe and healthful workplace for their employees, and must follow OSHA standards to prevent injuries and illnesses.
## Section 3: Questions and Answers
**Q:** What are some common types of discrimination in the workplace?
**A:** Some common types of discrimination in the workplace include race, color, religion, sex, national origin, disability, age, and genetic information.
**Q:** Can an employer require an employee to work overtime?
**A:** Yes, an employer can require an employee to work overtime if the employee is exempt from overtime pay requirements. However, if the employee is non-exempt, the employer must pay overtime for any hours worked over 40 in a week.
**Q:** What is the minimum wage in my state?
**A:** The minimum wage varies by state, so you would need to check with your state's department of labor to find out what the current minimum wage is.
## Section 4: Practical Examples
Let's say you own a small business and you want to hire a new employee. You post a job opening on your website and receive several applications. After reviewing the applications, you decide to interview three candidates. During the interviews, you notice that two of the candidates are very qualified but one of them is not. You decide to hire the most qualified candidate.
In this scenario, you have followed the at-will employment principle by hiring the most qualified candidate. You have also followed wage and hour laws by offering a fair wage and complying with any overtime requirements. Finally, you have followed anti-discrimination laws by not treating any candidate unfairly based on their race, color, religion, sex, national origin, disability, age, or genetic information.
## Section 5: Glossary
- At-will employment: A type of employment where an employee can generally be fired at any time, for any reason or no reason at all, unless the employee has a written contract that states otherwise.
- Wage and hour laws: Laws that set minimum wages, maximum hours, and other conditions of employment such as overtime pay, meal breaks, and rest periods.
- Discrimination and harassment: Prohibited practices that include treating someone unfavorably because of their race, color, religion, sex, national origin, disability, age, or genetic information.
- Workplace safety: The responsibility of employers to provide a safe and healthful workplace for their employees, and to follow OSHA standards to prevent injuries and illnesses.
## Conclusion
Understanding employment law is essential for both employers and employees. By following the principles of at-will employment, wage and hour laws, anti-discrimination laws, and workplace safety laws, you can create a fair and safe work environment for everyone.

The present invention relates to a substrate processing apparatus and a substrate processing method for consecutively processing substrates.
2. Description of the Related Art
In the manufacturing process of a semiconductor device, a batch processing, in which a plurality of semiconductor wafers are processed simultaneously, and a single wafer processing, in which semiconductor wafers are processed one by one, are selected appropriately in accordance with, for example, the kind of the processing and the number of semiconductor wafers to be processed.
For example, Japanese Patent Disclosure (Kokai) No. 10-335298 discloses a processing system comprising a plurality of process units for consecutively performing a plurality of different kinds of processing that deeply relates to each other with respect to a semiconductor wafer, and a transfer means for transferring the semiconductor wafer among these process units. The particular processing system was constructed in the past to include as a plurality of process units a plurality of batch process units alone or a plurality of single wafer process units alone.
However, various materials have come to be used in recent years for the manufacture of a semiconductor device. In this connection, various new processing methods have come to be proposed. Such being the situation, where a plurality of different kinds of processing are carried out consecutively, a large difference in the processing time is generated depending on the kind of the processing that is carried out. If the particular processing is carried out by the conventional processing system quoted above, a serious problem is generated that the through-put of the entire processing system is lowered.
It may be possible to prevent the through-put of the entire processing system from being lowered by constructing a single processing system such that the number of process units for carrying out a processing requiring a long processing time is larger than the number of process units for carrying out a processing that does not require a long processing time. In this case, however, it is unavoidable for the entire processing system to be rendered bulky. Also, the number of process units included in the processing system is increased so as to render costly the processing system. Further, an additional problem is generated that the construction and the control relating to the supply and the discharge of the processing fluid used in each of the process units are rendered complex, with the result that good processed articles are unlikely to be obtained.

EDITORIAL: Adland could offer remedy to obesity

Obesity is giving advertising a bad name. Britain is becoming a nation of cholesterol-filled fatties dicing with death from heart attacks, strokes or cancer and advertising must take much of the blame for it.

Or so the health lobby would have everyone believe.

Faced with such relentless and not always fair criticism, it's no wonder that snack food manufacturers and their agencies are usually vilified as the problem when they could be part of the solution.

At least Sport England, which is responsible for promoting the Government's sporting objectives, recognises advertising's potential to influence the situation positively by shortlisting four agencies to develop a national anti-obesity campaign. It would be churlish in the extreme not to wish it success. Whether it has a realistic chance of reducing society's collective waistline is highly debatable, particularly since obesity is predominant among poor families who have always proved stubbornly resistant to what they consider "nannying" messages.

The scale of the problem is huge in every respect. Obesity is said to be responsible for 31,000 premature deaths in the UK each year; one in 12 children is obese by the age of six, almost 24 million adults in the IK are overweight too- and the number is rising. The issue is a health "timebomb" which is expected to cost a beleaguered NHS £3.6 billion a year by the end of the decade. These statistics are alarming enough to ensure that the obesity problem will haunt the ad industry for many years to come.

Obesity is a complex issue with more than one trigger and the solution isn't helped by the lack of a joined-up Government response to it. The Department of Health, the Food Standards Agency and Ofcom are all grappling with the problem. Meanwhile, ministers confine themselves to a handful of pilot projects rather than a broad scale approach. A £77 million scheme to give all four- to six-year-olds a piece of fruit every school day will have little impact on diet and has been rightly condemned as a ludicrous waste of money when some schools don't even have clean drinking fountains.

The fact is officialdom and society's changing habits have fuelled the problem of obesity far more than advertising. The growing sales of council-owned playgrounds to developers, the prevailing car-dominated and couch potato culture and working parents who can't be bothered to cook and opt for takeaways are the main reasons for the obesity explosion.

With Tessa Jowell, the culture secretary, having recognised the pointlessness of a ban on snack food advertising, perhaps it is time for the ministers to recognise the bond companies such as Cadbury and Coca-Cola have with their consumers and to use it to their advantage.

Lesson: Introduction to Advertising and its Role in Society

Advertising is a powerful tool used by businesses to promote their products or services to potential customers. It plays an essential role in our society, shaping our preferences, beliefs, and behaviors. In this lesson, we will explore the basics of advertising, its history, and its impact on society.

**Section 1: What is Advertising?**

Advertising is a form of communication used to persuade people to buy or use a product or service. It is a paid form of mass communication that uses various media, such as print, radio, television, and the internet, to reach a target audience. Advertisers use creative and persuasive messages to attract attention and create interest in their products or services.

**Section 2: History of Advertising**

The history of advertising can be traced back to ancient civilizations, where merchants used posters and signage to promote their goods. However, modern advertising began in the late 19th century with the rise of consumer culture and the growth of mass media. In the early 20th century, advertising agencies were established to help businesses create effective advertising campaigns. Today, advertising is a multi-billion dollar industry that plays a significant role in shaping our culture and economy.

**Section 3: Impact of Advertising on Society**

Advertising has both positive and negative effects on society. On one hand, it helps businesses grow, creates jobs, and provides consumers with information about products and services. On the other hand, it can contribute to materialism, consumerism, and unrealistic expectations about beauty and success. Advertisers often use stereotyping and sexist messaging, which can reinforce negative social norms. Additionally, advertising can influence children's behavior and beliefs, leading to unhealthy eating habits and a distorted view of body image.

**Section 4: Critical Thinking Questions**

1. How does advertising shape our preferences and beliefs?
2. Can advertising be a force for good in society?
3. How does advertising affect children and their development?

**Glossary**
- Advertising: A form of communication used to persuade people to buy or use a product or service.
- Consumer Culture: A social and economic order that encourages the purchase and consumption of goods and services.
- Mass Media: A medium that disseminates information to a large audience.

**Conclusion**

Advertising plays a crucial role in our society, shaping our preferences and beliefs. While it can contribute to materialism and consumerism, it can also be a force for good when used responsibly. By understanding the impact of advertising on society, we can become more critical thinkers and make informed decisions about the products and services we choose to support.

Human metapneumovirus infection in hematopoietic stem cell transplant recipients: high-resolution computed tomography findings.
To review the high-resolution computed tomography (CT) findings in hematopoietic stem cell transplant (HCT) recipients who had proven human metapneumovirus (HMPV) pneumonia. The study included 5 HCT recipients who had proven HMPV pneumonia. The patients included 4 men and 1 woman ranging in age from 23 to 58 years (mean age = 42 years). The CT scans were assessed for the presence, appearance, size, and distribution of parenchymal abnormalities. Human metapneumovirus was isolated in all 5 patients in this series. None of these patients had any other infectious organism identified in cultures or bronchoalveolar lavage. The predominant CT findings were bilateral abnormalities in all patients, consisting primarily of a mixture of patterns, including, most commonly, ground-glass attenuation and nodular opacities. Areas of ground-glass opacification had no zonal predominance and were bilateral, asymmetric, and patchily distributed. Multiple nodules were identified in 4 (80%) of 5 patients. Nodules were multiple; less than 5 nodules were identified in 1 case, and 5 to 10 nodules were identified in 3 cases. All nodules in all cases were less than 10 mm in diameter. Areas of air-space consolidation were identified in 2 (40%) patients. All patients were available for follow-up; lesions improved in 4 patients. The thin-section CT manifestations of HMPV pneumonia usually consist of a mixture of patterns, including, most commonly, ground-glass attenuation and nodular opacities.

Lesson: Introduction to Computed Tomography (CT) Scans

Computed tomography (CT) scans are a type of medical imaging that uses X-rays and computer technology to create detailed images of the body. These images can help doctors diagnose and treat a variety of medical conditions, including lung infections like the one described in the input text. In this lesson, we will learn about the basics of CT scans, including how they work, what they can show, and how they can be used in medicine.

### Section 1: What is a CT scan?

A CT scan is a type of medical imaging that uses X-rays and computer technology to create detailed images of the body. These images can show the size, shape, and position of organs, tissues, and bones. CT scans are often used to diagnose and treat conditions such as cancer, heart disease, and brain injuries.

### Section 2: How does a CT scan work?

A CT scan works by taking a series of X-ray images from different angles around the body. These images are then combined by a computer to create a detailed, cross-sectional view of the body's internal structures. The amount of X-ray exposure used during a CT scan is greater than that used in regular X-rays, so it is important to minimize radiation exposure by only performing the scan when necessary.

### Section 3: What can a CT scan show?

CT scans can show a wide range of information about the body's internal structures. For example, a chest CT scan can show if there is any damage or disease in the lungs, such as the case described in the input text. CT scans can also show the size and shape of tumors, the extent of damage from a stroke, or the location of a blood clot.

### Section 4: How are CT scans used in medicine?

CT scans are an important tool in modern medicine. They can be used to diagnose and treat many different conditions, including cancer, heart disease, and brain injuries. Doctors may use CT scans to:

- Diagnose a condition: CT scans can help doctors identify the cause of symptoms such as pain, swelling, or abnormal bleeding.
- Plan treatment: CT scans can help doctors determine the best course of treatment for a patient.
- Monitor progress: CT scans can be used to track how well a patient is responding to treatment and to see if any changes have occurred in the body.
- Guide procedures: CT scans can help doctors locate and guide instruments to the correct area of the body during surgery or other procedures.

### Section 5: Conclusion

In conclusion, CT scans are an important tool in modern medicine. They can provide valuable information about the body's internal structures and help doctors diagnose and treat a wide range of conditions. By understanding the basics of CT scans, we can better appreciate their importance in the field of medicine and how they can be used to improve patient care.
