Lesson: Introduction to Cryptocurrencies

Overview:
In this lesson, we will learn about cryptocurrencies, a new form of digital money that uses cryptography for security. We will cover the basics of cryptocurrencies, their history, how they work, and their potential impact on society.

Section 1: Introduction to Cryptocurrencies

**What are cryptocurrencies?**
Cryptocurrencies are a new form of digital money that use cryptography for security. They are decentralized, meaning they are not controlled by any government or central authority. The most well-known cryptocurrency is Bitcoin, which was created in 2009.

**Why were cryptocurrencies created?**
Cryptocurrencies were created in response to a lack of trust in traditional financial systems. They provide an alternative to traditional banking systems, which are often slow and expensive. Cryptocurrencies allow people to send and receive money quickly and cheaply, without the need for a middleman like a bank.

**How do cryptocurrencies work?**
Cryptocurrencies use a technology called blockchain to record transactions. Blockchain is a digital ledger that records all transactions made with a particular cryptocurrency. It is secure and transparent, meaning anyone can see all the transactions that have ever been made.

Section 2: History of Cryptocurrencies

**When were cryptocurrencies first created?**
The first cryptocurrency, Bitcoin, was created in 2009 by an anonymous person or group of people known as Satoshi Nakamoto. Since then, many other cryptocurrencies have been created, including Ethereum, Litecoin, and Ripple.

**Why did Bitcoin become popular?**
Bitcoin became popular because it provided a new way for people to send and receive money without the need for a bank. It also allowed people to invest in a new asset class that was not controlled by any government or central authority.

**What impact have cryptocurrencies had on society?**
Cryptocurrencies have had a significant impact on society. They have disrupted traditional financial systems and provided new opportunities for people to invest in digital assets. They have also raised concerns about their potential use in illicit activities such as money laundering and terrorism financing.

Section 3: How Cryptocurrencies Work

**What is a blockchain?**
A blockchain is a digital ledger that records all transactions made with a particular cryptocurrency. It is secure and transparent, meaning anyone can see all the transactions that have ever been made.

**How does mining work?**
Mining is the process by which new transactions are added to the blockchain. Miners use powerful computers to solve complex mathematical problems. Once a problem is solved, the miner adds the verified transaction to the blockchain and receives a reward in the form of cryptocurrency.

**What is a wallet?**
A wallet is a software program that allows users to send and receive cryptocurrencies. Wallets store the user's private key, which is used to sign transactions and prove ownership of cryptocurrencies.

Section 4: Potential Impact of Cryptocurrencies

**Could cryptocurrencies replace traditional currencies?**
While cryptocurrencies have gained significant attention and adoption, it is unlikely that they will completely replace traditional currencies. However, they may become a significant part of the global financial system, providing new opportunities for investment and financial inclusion.

**What challenges do cryptocurrencies face?**
Cryptocurrencies face several challenges, including regulatory uncertainty, volatile prices, and limited acceptance by businesses. These challenges may slow their adoption, but they are likely to continue to play an important role in the global financial system.

Conclusion:
Cryptocurrencies are a new form of digital money that use cryptography for security. They provide an alternative to traditional banking systems, allowing people to send and receive money quickly and cheaply without the need for a middleman. While they have gained significant attention and adoption, they face several challenges, including regulatory uncertainty and limited acceptance by businesses. However, they are likely to continue to play an important role in the global financial system.

Public transportation coming to the Express Lanes

WASHINGTON – Beginning this January, the Fairfax Connector bus service will provide a public transportation option on the 495 Express Lanes to help commuters avoid Beltway traffic.

The buses, which will travel 55 m.p.h. on average, will run four routes from Burke Centre to Tysons Corner. The proposed cost for a one-way fare is $3.65. However, VRE passengers transferring off of the Manassas line will be able to travel on the bus routes for free.

The hope is that the public transportation option will result in fewer people choosing to drive and less traffic on the road for those who need to do so.

“The more cars that we can take off the road, the less traffic we will ultimately have,” says Ellen Kamilakis from the Fairfax County Department of Transportation.

The Burke-to-Tysons route will begin Jan. 14, 2013. Additional routes, including one from Springfield/Saratoga to Tysons Corner and another from Lorton VRE to Tysons Corner, are planned for the spring.

Lesson: Introduction to Public Transportation

## Chapter 1: Understanding Public Transportation

### Section 1.1: What is Public Transportation?
Public transportation refers to any form of transportation that is available to the general public, as opposed to private transportation such as personal cars or taxis. It includes options like buses, trains, subways, and ferries.

### Section 1.2: Why Use Public Transportation?
There are several reasons why people might choose to use public transportation instead of driving their own cars. Some of these reasons include:
- Reducing traffic congestion: When more people use public transportation, there are fewer cars on the road, which can help reduce traffic congestion.
- Saving money: Public transportation is often cheaper than owning and maintaining a car, especially when you factor in the cost of gas, insurance, and maintenance.
- Being environmentally friendly: Public transportation produces fewer emissions than cars, so using it can help reduce air pollution and greenhouse gas emissions.
- Staying safe: Public transportation is generally considered safer than driving, as there are fewer accidents per mile traveled compared to cars.

### Section 1.3: How Does Public Transportation Work?
Public transportation systems work by providing scheduled routes and times for buses, trains, or other vehicles to pick up passengers at designated stops or stations. These routes are designed to cover a wide area, allowing people to travel from one end of the city to another without having to rely on private transportation.

### Section 1.4: Types of Public Transportation
There are several types of public transportation available, including:
- Buses: These are large vehicles that can carry many passengers and travel long distances. They often follow fixed routes and schedules.
- Trains: Trains are typically faster than buses and can travel longer distances without stopping. They often have separate carriages for different classes of service (e.g., first class, business class).
- Subways: Subways are underground train systems that allow people to travel quickly and efficiently through urban areas without being slowed down by traffic.
- Ferries: Ferries are boats that transport passengers across bodies of water such as rivers or lakes. They can be used for both short and long distances.

### Section 1.5: Benefits of Public Transportation
There are several benefits associated with using public transportation, including:
- Environmental benefits: Public transportation produces fewer emissions than cars, so using it can help reduce air pollution and greenhouse gas emissions.
- Economic benefits: Public transportation can save individuals money on gas, insurance, and maintenance costs. It also helps reduce traffic congestion, which can lead to time savings for everyone on the road.
- Social benefits: Public transportation can help promote social equity by providing affordable access to jobs, education, healthcare, and other essential services.

### Section 1.6: Challenges of Public Transportation
While public transportation has many benefits, there are also some challenges associated with using it. Some of these challenges include:
- Limited service: Public transportation may not run 24/7, and there may be gaps in coverage or service hours that make it difficult for some people to access certain areas or services.
- Crowding: During peak times, public transportation can become very crowded, making it uncomfortable for passengers and potentially leading to delays.
- Reliability: Public transportation can be affected by factors such as weather or traffic, which may cause delays or cancellations.

### Section 1.7: Examples of Public Transportation Systems
Some examples of public transportation systems around the world include:
- New York City Subway: This subway system serves over 472 stations and is one of the busiest in the world.
- London Underground: Also known as "the tube," this subway system serves over 270 stations and is one of the oldest in the world.
- Tokyo Metro: This metro system serves over 200 stations and is known for its efficiency and cleanliness.
- Hong Kong MTR: This metro system serves over 100 stations and is known for its modern design and advanced technology.

## Chapter 2: Understanding the 495 Express Lanes

### Section 2.1: What are the 495 Express Lanes?
The 495 Express Lanes are a toll road in Northern Virginia that allows drivers to pay a toll to use the lanes, which are separated from regular traffic lanes. The goal of the express lanes is to reduce traffic congestion and provide a faster and more reliable commute for drivers.

### Section 2.2: How Do the 495 Express Lanes Work?
The 495 Express Lanes work by using electronic toll collection (ETC) technology. Drivers must have an E-ZPass transponder or video toll account to use the lanes. The tolls vary based on time of day and traffic conditions, with higher tolls during peak hours and lower tolls during off-peak hours. The tolls are designed to encourage carpooling, as drivers with multiple passengers can receive discounted tolls.

### Section 2.3: Benefits of the 495 Express Lanes
There are several benefits associated with the 495 Express Lanes, including:
- Faster commute times: By providing a dedicated lane for drivers willing to pay a toll, the express lanes can help reduce congestion and provide a smoother, more reliable commute.
- Reduced traffic congestion: The express lanes are designed to encourage carpooling, which can help reduce the number of vehicles on the road and alleviate traffic congestion.
- Improved air quality: With fewer cars on the road, there will be less air pollution and greenhouse gas emissions from vehicles.

### Section 2.4: Challenges of the 495 Express Lanes
While the 495 Express Lanes have many benefits, there are also some challenges associated with them. Some of these challenges include:
- Cost: Drivers must pay a toll to use the express lanes, which can add up over time.
- Accessibility: The express lanes are only available to drivers who have an E-ZPass transponder or video toll account, which may not be accessible to all drivers.
- Equity: There is concern that the express lanes may disproportionately benefit wealthier drivers who can afford to pay the tolls, while exacerbating traffic congestion for those who cannot.

## Chapter 3: Using Public Transportation on the 495 Express Lanes

### Section 3.1: Why Use Public Transportation on the 495 Express Lanes?
There are several reasons why people might choose to use public transportation on the 495 Express Lanes, including:
- Reducing traffic congestion: By taking public transportation, there will be fewer cars on the road, which can help reduce traffic congestion and improve the overall commute experience.
- Saving money: Public transportation is often cheaper than driving and paying tolls, especially for those who do not have an E-ZPass transponder or video toll account.
- Being environmentally friendly: Public transportation produces fewer emissions than cars, so using it can help reduce air pollution and greenhouse gas emissions.
- Staying safe: Public transportation is generally considered safer than driving, as there are fewer accidents per mile traveled compared to cars.

### Section 3.2: How to Use Public Transportation on the 495 Express Lanes
To use public transportation on the 495 Express Lanes, follow these steps:
1. Check the schedule for your chosen public transportation route to ensure that it aligns with your commute times.

Heterogeneity in host-parasitoid interactions: 'Aggregation of risk' and the 'CV(2) > 1 Rule'.
In host-parasitoid interactions the coefficient of variation (CV) of the risk of parasitism measures, at least approximately, the stabilizing influence of many forms of heterogeneity. This realization emphasizes the underlying similarity of these heterogeneities, and should end two decades of confusion about how to study them in nature. The first applications of this approach suggest that roughly one-third of systems studied show substantial measurable heterogeneity. Proper use of the CV measure, however, requires that the density-dependent processes linking this static phenomenon to temporal population dynamics also be examined; this has yet to be done for any system.

textbook:
Lesson Title: Understanding Heterogeneity in Host-Parasitoid Interactions

Introduction:
Host-parasitoid interactions are complex relationships between organisms that involve both predation and cooperation. In these interactions, the stability of populations is often influenced by the level of heterogeneity present. Heterogeneity refers to the variation in environmental conditions, such as resource availability or predation pressure, that can affect the behavior and survival of organisms.

Core Value:
The coefficient of variation (CV) is a valuable tool for measuring the level of heterogeneity in host-parasitoid interactions. It provides a quantitative measure of the variability in the risk of parasitism, which can help researchers understand the stabilizing influence of heterogeneity on population dynamics.

Lesson Outline:
I. What is Heterogeneity?
- Definition and explanation of heterogeneity in host-parasitoid interactions
- Examples of environmental factors that contribute to heterogeneity, such as resource availability and predation pressure
- Discussion of how heterogeneity can affect population stability and dynamics

II. Measuring Heterogeneity with the Coefficient of Variation (CV)
- Explanation of the CV measure and how it can be used to quantify the level of heterogeneity in host-parasitoid interactions
- Discussion of the importance of properly using the CV measure to study heterogeneity in nature
- Examples of applications of the CV measure in host-parasitoid interactions

III. Applying the CV Measure to Real-World Scenarios
- Discussion of how the CV measure can be used to study heterogeneity in different host-parasitoid systems
- Examples of how different environmental factors can influence the level of heterogeneity in these systems
- Analysis of how temporal population dynamics are affected by heterogeneity

Conclusion:
Understanding the role of heterogeneity in host-parasitoid interactions is crucial for predicting and managing population dynamics. By using the CV measure, researchers can quantify the level of heterogeneity in these interactions and examine its effects on population stability and dynamics. This knowledge can be applied to a wide range of host-parasitoid systems, helping to inform conservation and management strategies.

text: A US-based group, Forest Trends, says many countries need to do their part to crack down on logging in Papua New Guinea.. Forest Trends has released a new report titled "Logging, Legality, and Livelihoods in PNG" which says the commercial logging industry in Papua New Guinea is unsustainable and some of it illegal.. The report analysed five independent reviews of the timber industry conducted between 2000 and 2005.. The president of Forest Trends, Michael Jenkins, says although the report calls on the PNG government to better monitor the timber industry, other countries can also assist.. "Countries like China, the US and Europe who are all involved in this on terms of receiving a product could send stronger market signals back to PNG to say we want to be partners with you but we want to make sure the wood comes from sustainably managed sources.".

# Lesson: How to Choose the Right Lighting for Your Bathroom

## Introduction
Lighting is an essential part of any room, including the bathroom. Good lighting can enhance the appearance of your space and make it more functional. In this lesson, we will learn about the different types of bathroom lighting and how to choose the right one for your needs.

## Section 1: Types of Bathroom Lighting

There are three main types of bathroom lighting: ambient, task, and accent.

1. Ambient lighting provides general illumination for the entire room. This type of lighting can be achieved with ceiling lights, wall sconces, or mirrors with built-in lights.

2. Task lighting is focused on specific areas of the bathroom, such as the sink or vanity. This type of lighting is usually brighter and more direct than ambient lighting. Examples of task lighting include vanity lights and under-cabinet lights.

3. Accent lighting adds visual interest and drama to the space. This type of lighting can be achieved with decorative fixtures, such as chandeliers or pendant lights.

## Section 2: How to Choose the Right Lighting for Your Bathroom

1. Assess the size of your bathroom: Larger bathrooms can accommodate multiple light sources, while smaller bathrooms may require a more streamlined approach.

2. Consider the function of each area: Determine whether you need general illumination, task lighting, or both.

3. Choose the appropriate lighting fixtures: Select fixtures that complement the style and theme of your bathroom. For example, a modern bathroom may benefit from sleek, minimalist lighting fixtures, while a traditional bathroom may benefit from ornate chandeliers or sconces.

4. Take into account the color temperature: Warm light (2700K) creates a cozy atmosphere, while cool light (4000K) can make the space feel more refreshing.

5. Consider energy efficiency: LED lights are energy-efficient and long-lasting, making them a good choice for bathrooms.

## Section 3: Practical Examples and Real-World Scenarios

1. A small bathroom with a vanity and mirror may benefit from a combination of ambient and task lighting. A ceiling light and vanity light can provide general illumination, while a mirror with integrated lighting can serve as both an accent and task lighting source.

2. A master bathroom with a large soaking tub may benefit from ambient lighting provided by a chandelier or pendant lights. Task lighting can be provided by wall sconces or under-cabinet lights near the vanity.

3. A powder room with limited counter space may require task lighting for applying makeup or shaving. A wall-mounted light or a lighted mirror can provide the necessary brightness.

## Conclusion

In conclusion, choosing the right lighting for your bathroom is essential for both functionality and aesthetics. By considering the size, function, and style of your space, you can select the appropriate lighting fixtures to create a beautiful and practical bathroom.

Lesson: Protein Folding and Disulfide Bond Formation in Plants

Introduction:
Proteins are essential macromolecules that perform various functions in living organisms. They are made up of amino acids, which fold into specific three-dimensional structures that determine their function. Disulfide bonds are covalent linkages between two cysteine amino acids within a protein or between two separate polypeptide chains. These bonds play a crucial role in maintaining protein structure and stability.

In plants, protein disulfide isomerase (PDI) is responsible for catalyzing disulfide bond formation and is involved in various cellular processes such as photosynthesis, respiration, and defense against pathogens. PDI has multiple homologs in Arabidopsis thaliana, which exhibit variation in their subcellular localization and protein folding activity.

Objectives:
- Understand the importance of protein folding and disulfide bond formation in plants
- Identify the roles of PDI and its homologs in Arabidopsis thaliana
- Explain the variations in subcellular localization and protein folding activity among PDI homologs

Section 1: Introduction to Protein Folding and Disulfide Bonds

1.1 What is protein folding?
Protein folding refers to the process by which a linear chain of amino acids folds into a specific three-dimensional structure, which is essential for its function. The correct folding of a protein is crucial for its activity, stability, and interactions with other molecules.

1.2 Why are disulfide bonds important in protein folding?
Disulfide bonds are covalent linkages formed between two cysteine amino acids within a protein or between two separate polypeptide chains. They contribute to protein stability by maintaining the correct folding and preventing aggregation. Disulfide bonds also play a role in modulating protein activity and function.

Section 2: Protein Disulfide Isomerase (PDI) and Its Homologs in Arabidopsis thaliana

2.1 What is PDI and what is its role in plants?
PDI is an enzyme that catalyzes the formation of disulfide bonds in proteins. In plants, PDI is involved in various cellular processes such as photosynthesis, respiration, and defense against pathogens. It plays a critical role in maintaining protein structure and stability.

2.2 How many homologs of PDI are there in Arabidopsis thaliana?
There are multiple homologs of PDI in Arabidopsis thaliana, which exhibit variation in their subcellular localization and protein folding activity.

Section 3: Variation in Subcellular Localization and Protein Folding Activity among PDI Homologs

3.1 What factors contribute to the variation in subcellular localization and protein folding activity among PDI homologs?
The variation in subcellular localization and protein folding activity among PDI homologs can be attributed to differences in their amino acid sequences, post-translational modifications, and interactions with other proteins.

3.2 How do these variations affect the overall function of the plant?
The variations in subcellular localization and protein folding activity among PDI homologs can impact the overall function of the plant by altering the stability, activity, and interactions of proteins involved in essential cellular processes.

Amnesia: 'Lost' Memories in Mice Retrieved with Light

Memories that have been "lost" as a result of amnesia have recently been retrieved in mice using light, according to a new study.

This process, known as optogenetics, gives scientists hope that effective treatments may one day be possible for retrograde amnesia in humans - which follows traumatic injury, stress, or diseases such as Alzheimer's.

It has long been debated whether memory loss is caused by damage to the neurons that store memories, or from a blockage of access to those memories.

"The majority of researchers have favored the storage theory, but we have shown in this paper that this majority theory is probably wrong," researcher Susumu Tonegawa from MIT said in a statement. "Amnesia is a problem of retrieval impairment."

When a memory is being formed, scientists speculate that a population of neurons is activated and undergoes lasting physical or chemical changes. This collection of neurons, known as "memory engram cells," can be triggered by a specific sight or smell, for example.

By using optogenetics - in which proteins are added to neurons to allow them to be activated with light - Tonegawa and his colleagues showed for the first time that these neurons do indeed exist, in the region of the brain called the hippocampus.

However, it remained to be seen whether light could induce chemical changes in these neurons linked to memory consolidation. This involves "long-term potentiation" (LTP), or the strengthening of synapses that allow neurons to communicate with one another.

To find out if these chemical changes do indeed take place, the MIT team gave mice in the study a drug called anisomycin, which blocks protein synthesis within neurons and inhibits memory consolidation. But when they tried to reactivate the newly formed memory just a day later using an emotional trigger, they were unsuccessful.

"So even though the engram cells are there, without protein synthesis those cell synapses are not strengthened, and the memory is lost," Tonegawa explained.

On the other hand, when neurons involved in encoding the memory were stimulated with pulses of light, reactivating the protein synthesis, the animals were able to recall the memory in full.

"If you test memory recall with natural recall triggers in an anisomycin-treated animal, it will be amnesiac, you cannot induce memory recall," Tonegawa said. "But if you go directly to the putative engram-bearing cells and activate them with light, you can restore the memory, despite the fact that there has been no LTP."

These results suggest that mice that received the drug did not really "lose" their memory, but rather that access to the memory was simply blocked.

Further research is needed to confirm this mechanism, but it is a step in the right direction to better understanding and treating retrograde amnesia in human patients.

1. How does optogenetics work in mice?
2. What are memory engram cells?
3. How can optogenetics help retrieve lost memories?
4. What are some real-world applications of optogenetics for memory retrieval?

Section 3: Math and Science Concepts

1. How do neurons communicate with each other?
2. What is the role of neurotransmitters in memory formation and retrieval?
3. How do synapses change during memory formation and retrieval?
4. What is the difference between short-term and long-term memory?

Glossary:
- Neuron: A specialized cell in the nervous system that transmits information through electrical and chemical signals.
- Neurotransmitter: A chemical messenger that carries signals across a synapse between neurons.
- Synapse: The junction between two neurons where information is transmitted between them.
- Memory engram cells: A collection of neurons that store a specific memory.

Conclusion:
Optogenetics is a promising technique that can help retrieve lost memories in mice with amnesia. By understanding the underlying mechanisms of memory formation and retrieval, scientists can potentially develop treatments for memory disorders in humans. This lesson has explored the theoretical and practical aspects of memory retrieval, as well as the math and science concepts that underlie this process. By applying these concepts to new problems, we can continue to advance our understanding of the brain and develop innovative solutions for memory-related issues.

Lesson: Alternative Burial Methods

Introduction:
In this lesson, we will learn about alternative burial methods that are eco-friendly and gentle on the environment. We will focus on aquamation, which is a water-based process that offers an alternative to flame cremation and burial.

Section 1: What is Aquamation?
Aquamation is a process that uses water instead of fire to return the body back to Mother Nature. It is an eco-friendly alternative to flame cremation and burial. The process involves placing the body in a large container filled with water and alkaline solution. The body is then heated to a high temperature, which breaks down the tissue. The remains are then washed away, leaving behind bone fragments that can be returned to the family.

Section 2: Why is Aquamation Eco-Friendly?
Aquamation is eco-friendly because it uses water instead of fire to return the body back to Mother Nature. It also uses less energy than flame cremation, which means it has a smaller carbon footprint. In addition, aquamation returns 20% more of the animal's cremains back to the owner compared to flame cremation. This means that families can have a more complete experience when saying goodbye to their loved ones.

Section 3: How does Aquamation Work?
Aquamation works by using a combination of heat, pressure, and alkaline solution to break down the tissue. The body is placed in a large container filled with water and alkaline solution. The container is then sealed and heated to a high temperature. The heat causes the tissue to break down, and the pressure forces the remains to be washed away. The bone fragments that are left behind can then be returned to the family.

Section 4: How much does Aquamation Cost?
Aquamation costs the same as traditional cremation. This means that families do not have to pay extra for an eco-friendly option.

Conclusion:
In this lesson, we learned about aquamation, an eco-friendly alternative to flame cremation and burial. We learned that it is a water-based process that uses less energy and has a smaller carbon footprint than flame cremation. We also learned how the process works and why it is eco-friendly. Finally, we learned that aquamation costs the same as traditional cremation. By choosing aquamation, families can have a more complete experience when saying goodbye to their loved ones while also making a positive impact on the environment.

Answer: By gathering feedback from users and making changes based on their suggestions.

Definition: Feedback is information that is given to someone to help them improve something they are doing.

Example: The kids test their toy with several groups of children and ask for their feedback. They make changes based on what the kids say and continue testing until they are satisfied with the results.

Conclusion:
In this lesson, we learned about design thinking and how it can be used to create solutions that meet the needs of others. By following the steps of empathy, define, ideate, prototype, and test, we can come up with creative and effective solutions to problems. We also learned that design thinking is a way of thinking that can be applied to many different types of projects and challenges.

Glossary:
- Empathy: the ability to understand and share the feelings of another person
- Problem statement: a clear and concise description of the challenge that needs to be solved
- Prototype: a simple model or version of an idea that can be tested and improved
- Feedback: information that is given to someone to help them improve something they are doing.


text: Hi All,. I'm relatively new to Tableau and have created a few basic dashboards.. I'm currently working on a report where I have a number of measures to show % difference and the difference in £, however the end user does not want to see both % and £ together and have requested to group the % and £ as you can in excel, hence with one click it displays % and this can then easily be hidden with the +/- function. See below.. Is something similar possible within tableau?. quick thought would be creating two sheets and use parameter to switch.. Thanks Amit, the article was very useful and did the trick.. glad to know it worked for you. Become a Viz Whiz on the Forums! Support the Community and master Tableau.

textbook:
Sure, I can help you with that! In Tableau, you can use the "Show Me" feature to display both percentage and monetary values separately. Here are the steps:
1. Drag the measure you want to display as a percentage onto the worksheet.
2. Right-click on the measure and select "Show Me" > "Percentage".
3. Now, you can add the second measure to the worksheet and format it as currency.
4. Right-click on the second measure and select "Show Me" > "Currency".
5. You can now use the "+" and "-" buttons to hide and show the measures as needed.
Alternatively, you can create a parameter that allows the user to switch between displaying the measures as percentage or currency. Here are the steps:
1. Create a new parameter and name it "Display As".
2. Add two options to the parameter: "Percentage" and "Currency".
3. Drag the parameter onto the worksheet and set its type to "Dimension".
4. Drag the two measures onto the worksheet and set their type to "Measure".
5. Right-click on each measure and select "Show Me" > "Parameters" > "Display As".
6. Choose the appropriate option based on the user's selection.
7. Finally, you can use the "Switching" feature to allow the user to switch between the two options with a single click.
I hope this helps! Let me know if you have any further questions.

Lesson: How to Analyze Literature

## Introduction

Literature is a form of art that uses language to express ideas and emotions. It can take many forms, including novels, poetry, plays, and short stories. Analyzing literature means breaking down the text to understand its meaning and themes. In this lesson, we will learn how to analyze literature by examining a passage from "I Know Why the Caged Bird Sings" by Maya Angelou.

## Section 1: Theoretical Concepts

Theoretical concepts are the foundation of literary analysis. They help us understand the text and its meaning. Some of the key concepts we will explore in this lesson include:

1. Symbolism: A symbol is an object, person, or event that represents a deeper meaning or idea.
2. Theme: A theme is the underlying message or meaning of a work of literature.
3. Irony: Irony is when the outcome is different from what was expected.
4. Imagery: Imagery is the use of descriptive language to create mental pictures or sensory experiences.

## Section 2: Questions and Answers

Now that we know the theoretical concepts, let's apply them to our passage from "I Know Why the Caged Bird Sings."

Passage: "In the dusk of a glowing day, when the shadows were long and golden and the sun was a red and silver disk sinking toward the horizon, I stood on the porch with Momma."

1. What is the symbolism of the "glowing day" and "long and golden shadows"?
2. What is the theme of the passage?
3. Is there any irony in the passage? If so, what is it?
4. What type of imagery is used in the passage?

## Section 3: Definitions and Examples

Now that we have explored the theoretical concepts and asked questions, let's define them and provide examples.

1. Symbolism: The "glowing day" and "long and golden shadows" symbolize the beauty and warmth of the outdoors.
2. Theme: The theme of the passage is the beauty and simplicity of nature.
3. Irony: There is no irony in the passage.
4. Imagery: The imagery used in the passage is sensory, as we can see the "glowing day" and "long and golden shadows."

## Conclusion

By analyzing the passage from "I Know Why the Caged Bird Sings," we have learned about the theoretical concepts of symbolism, theme, irony, and imagery. We have also applied these concepts to a literary text. This skill is essential for understanding and interpreting literature. By practicing literary analysis, we can gain a deeper understanding of the messages and themes in the works we read.

Lesson: Introduction to Economic Systems

### Section 1: Understanding Economic Systems

An economic system is a way of organizing the production, distribution, and consumption of goods and services in a society. There are different types of economic systems, including traditional, command, market, and mixed economies.

**Traditional Economy:** In a traditional economy, people rely on customs and traditions to make decisions about producing and consuming goods and services. They often live off the land and do not use money to trade.

**Command Economy:** A command economy is centrally planned and controlled by the government, which makes all major economic decisions, such as allocating resources and setting production quotas.

**Market Economy:** A market economy is driven by supply and demand. Prices, production, and resource allocation are determined by the interactions of businesses and consumers, with little or no government intervention.

**Mixed Economy:** A mixed economy combines elements of both market and command economies. The government may regulate certain industries while allowing others to operate freely.

### Section 2: Comparing Economic Systems

**Traditional vs. Command Economy:** In a traditional economy, decisions are made based on customs and traditions, while in a command economy, the government makes all major economic decisions.

**Command vs. Market Economy:** In a command economy, the government controls production and resource allocation, while in a market economy, prices, production, and resource allocation are determined by supply and demand.

**Market vs. Mixed Economy:** In a market economy, prices, production, and resource allocation are determined by supply and demand, while in a mixed economy, the government may regulate certain industries while allowing others to operate freely.

### Section 3: Applying Economic Systems

**Example:** Imagine you own a small business that sells handmade crafts. Your business operates in a market economy because you decide how much to produce, what prices to charge, and how to allocate your resources. You also compete with other businesses that sell similar products, and you must adapt to changes in consumer demand.

**Conclusion:** Understanding economic systems is important for making informed decisions about production, distribution, and consumption of goods and services. By comparing and applying different economic systems, we can better understand how our actions impact the broader economy.

### Glossary
- Traditional economy: An economic system where people rely on customs and traditions to make decisions about producing and consuming goods and services.
- Command economy: An economic system where the government makes all major economic decisions, such as allocating resources and setting production quotas.
- Market economy: An economic system where prices, production, and resource allocation are determined by the interactions of businesses and consumers, with little or no government intervention.
- Mixed economy: An economic system that combines elements of both market and command economies.
- Supply and demand: The relationship between the quantity of a product that producers are willing to sell and the quantity that consumers are willing to buy at various prices.


text: This one’s in response (expansion) to a post from the lovely Ms. Campbell (@prsoapbox), who was kind enough to grace me with her company at dinner last week along with Ms. Vallejo and Ms. Sena. She recently brought us this blog post addressing the ethics in our chosen profession—the great world of public relations in its various forms.. As in many other fields, there are some bright lines that we dare not cross. Then there are those ethically grey areas. Yes (!)—there can be ethically grey areas, not everything is easily placed on a black or white square. These usually pop up when our own ethical rules for various areas of our life (personal and professional) come into conflict and we must step up and make the decision of what/which is most important to us.

Lesson: Ethics in Public Relations
Introduction:
Public relations is an essential part of any business, organization or individual's success. It involves managing the communication between the public and the individual or organization, and it requires a high level of integrity and ethical behavior. In this lesson, we will explore the importance of ethics in public relations, the bright lines that must not be crossed, and the ethically grey areas that require careful consideration.
Section 1: Introduction to Ethics in Public Relations
Ethics refers to the moral principles that govern a person's behavior or the conducting of an activity. In public relations, ethics play a crucial role in maintaining the reputation and credibility of an individual or organization. A public relations professional must act with honesty, transparency, and fairness to ensure that they maintain the trust of their clients and the public.
Section 2: Bright Lines in Public Relations
There are certain principles that are considered "bright lines" in public relations. These are clear and unambiguous rules that must never be violated. For example, public relations professionals must never lie or deceive the public. They must also avoid conflicts of interest and always act in the best interests of their clients.
Section 3: Ethically Grey Areas in Public Relations
While there are bright lines that must not be crossed, there are also ethically grey areas that require careful consideration. For example, a public relations professional may be asked to spin negative news to make it look positive. While this may be legal, it may not be ethical. Similarly, a public relations professional may be asked to engage in astroturfing, which involves creating the appearance of grassroots support for a product or cause. While this may be effective, it may also be dishonest.
Section 4: Conclusion
In conclusion, ethics plays a crucial role in public relations. Public relations professionals must act with integrity and transparency to maintain the trust of their clients and the public. While there are bright lines that must not be crossed, there are also ethically grey areas that require careful consideration. By understanding the importance of ethics in public relations, individuals and organizations can build a strong and positive reputation that will serve them well in the long run.
Glossary:
- Bright Lines: Clear and unambiguous rules that must never be violated.

Healthcare: the availability of unlimited profits is a powerful motivating force

KEY TAKEAWAY: Healthcare is now the single biggest sector of the US economy. It is bigger than big oil, bigger than big banking, and bigger even than the famous military-industrial complex that President Dwight Eisenhower warned about in his farewell speech. In 2013, the most generous estimate pegged the price of the military-industrial complex at $ 1.3 trillion, while healthcare expenditures in 2015 were $ 3.2 trillion, consuming nearly one of every five dollars spent in the US.

Today, like big oil and big banking, the medical-industrial complex has become so vast, so wealthy, and so powerful that it is increasingly insulated from the effects of its own errors and misdeeds. Virtually every major drug and medical device company has been caught in one or more scandals, and they pay massive fines as part of the cost of doing business.

Three historical developments lie at the center of the rise of the medical-industrial complex: the explosion of medical technology beginning in the 1960s; the passage of Medicare in 1965, along with the proliferation of private health insurance; and the Bayh-Dole Act of 1980. Together, these three developments drove the corporatization of medicine, with profound implications for the way healthcare is promoted, practiced, and regulated in the US.

One of the most powerful and rapidly growing participants in this burgeoning economic network is the medical device industry. Generating estimated revenues of more than $ 136 billion in the US in 2014, the implantable-device industry is even more lucrative for many of its component companies than the highly profitable pharmaceuticals industry.

Operating-profit margins for the largest companies include 30.0 percent for Zimmer Biomet (artificial joints), 28.6 percent for Medtronic, 25.8 percent for St. Jude Medical, and 23.1 percent for Stryker (orthopedic implants).

Johnson & Johnson’s device division squirreled away $ 7.2 billion in profits in 2012, while Medtronic pulled down $ 3.6 billion in profits that year. Ultra-high prices help fuel those giant profit margins: Medtronic charges approximately $ 19,000 for a neurostimulator used to treat back pain, which is four times what it costs to manufacture the device. Hospitals pay $ 4,500– $ 7,500 for a popular type of hip implant that costs $ 350 to manufacture. Hospitals are asked to sign confidentiality agreements, obliging them not to reveal their purchase prices.

Lesson: Understanding the Medical-Industrial Complex

Introduction

The medical-industrial complex is a term used to describe the interconnected network of pharmaceutical companies, healthcare providers, insurers, and government agencies that make up the healthcare industry in the United States. This complex system can be difficult to navigate, but understanding its structure and function is essential for anyone who wants to make informed decisions about their healthcare.

Section 1: The History of the Medical-Industrial Complex

The medical-industrial complex has its roots in the post-World War II era, when advances in medical technology and the passage of Medicare led to rapid growth in the healthcare industry. The explosion of medical technology beginning in the 1960s, combined with the passage of Medicare in 1965, led to the proliferation of private health insurance and the creation of a complex system of healthcare providers, insurers, and government agencies.

Section 2: How the Medical-Industrial Complex Works

The medical-industrial complex is a complex system that can be difficult to understand. At its core, however, are a few key players:

1. Pharmaceutical companies: These companies research, develop, and manufacture drugs that are prescribed by doctors and sold to patients. They also market these drugs aggressively to both doctors and consumers.

2. Healthcare providers: These are the doctors, hospitals, and other healthcare professionals who provide care to patients. They are often paid by insurance companies or the government for their services.

3. Insurers: These are the companies that provide health insurance to individuals and families. They negotiate rates with healthcare providers and pay for medical services.

4. Government agencies: These include organizations like the Food and Drug Administration (FDA), which regulates the pharmaceutical industry, and Medicare, which provides healthcare coverage to seniors.

Section 3: Understanding the Impact of the Medical-Industrial Complex

The medical-industrial complex has a significant impact on American society. It is responsible for a large portion of the nation's economic output, and it employs millions of people. However, it also faces significant challenges, including rising healthcare costs and concerns about the quality of care provided.

Section 4: Critical Thinking Questions

1. How does the medical-industrial complex impact your life?
2. What are some of the challenges facing the medical-industrial complex, and how might they be addressed?
3. How might the structure of the medical-industrial complex change in the future, and what impact could this have on healthcare in America?

Conclusion

Understanding the medical-industrial complex is essential for anyone who wants to make informed decisions about their healthcare. By learning about the history of the complex, how it works, and its impact on American society, you can become a more educated consumer and advocate for your own healthcare needs.
