FIG. 1 is a circuit diagram illustrating a related transmitter having a push-pull structure. FIG. 1 illustrates a circuit of the transmitter, which has a double stack structure driven in a push-pull manner.
Referring to FIG. 1, an MS1, which is a PMOS transistor, and an MS2, which is an NMOS transistor, are used as constant current sources. PMOS transistors MP1 and MP2, and NMOS transistors MN1 and MN2 are switching elements to determine the direction of current flow. The MP2 and MN1 are simultaneously turned on, and the MP1 and MN2 are simultaneously turned on, thereby supplying a constant current to a positive node 1 and a negative node 2.
A constant voltage is applied across a resistor Rterm by the constant current supplied to the positive node 1 and negative node 2. The constant voltage applied across the resistor Rterm is detected by a comparator 3. Meanwhile, the related transmitter additionally includes a common-mode feedback circuit to fix a common-mode voltage at a voltage vcom because the common-mode noise at the positive node 1 and negative node 2 is high.
The above-mentioned circuit of the related transmitter has three problems as follows. First, although voltage drop occurs at the MS1, MP2, resistor Rterm, resistor Rseri, MN2, and MS2 when the voltage at the positive node 1 is driven to be increased to a level higher than the voltage vcom, high voltage drop occurs at the resistive elements, namely, the MP2, Rterm, Rseri, and MN2 when the driving is achieved using a large current. For this reason, the voltage to be secured in the MS1 and MS2 becomes insufficient. As a result, it is difficult for the MS1 and MS2 to be driven as constant current sources. When the MP1 and MP2 cannot operate as large current sources, it is impossible to supply a large current to a capacitive load, namely, a capacitor Cload. When this happens, it may be impossible to achieve high-speed data transmission.
Second, a lot of time is needed for phase change of the voltage applied across the resistor Rterm when a large capacitive load, for example, the capacitor Cload, is driven. For this reason, it is impossible to charge the capacitor Cload to a normal voltage level in a high-speed operation. To solve this problem, it is necessary to supply a large current to the positive node 1 and negative node 2 upon changing the phase of the above-mentioned voltage. However, the amount of current is limited by the constant current sources. As a result, there is a problem in that it is difficult to achieve rapid phase change at the positive node 1 and negative node 2.
Third, it may be necessary to add the common-mode feedback circuit because the noise at the voltage vcom is high due to high output resistance of the positive node 1 and negative node 2.

Lesson: Understanding Circuit Diagrams and Transmitters

### Overview

In this lesson, we will learn about circuit diagrams and transmitters. We will start by understanding what a circuit diagram is and then move on to learn about the different components of a transmitter. Finally, we will analyze a circuit diagram of a transmitter with a push-pull structure.

### Section 1: Introduction to Circuit Diagrams

A circuit diagram is a graphical representation of an electrical circuit. It is used to show how different components are connected together in a circuit. Circuit diagrams are useful in designing and analyzing electronic circuits.

### Section 2: Understanding Transmitters

A transmitter is an electronic device that converts a signal from a source into a form that can be transmitted through a medium. Transmitters are used in communication systems, radar systems, and other electronic systems.

### Section 3: Analyzing a Circuit Diagram of a Transmitter with a Push-Pull Structure

FIG. 1 is a circuit diagram illustrating a related transmitter having a push-pull structure.

Referring to FIG. 1, an MS1, which is a PMOS transistor, and an MS2, which is an NMOS transistor, are used as constant current sources. PMOS transistors MP1 and MP2, and NMOS transistors MN1 and MN2 are used as switching elements to determine the direction of current flow.

The MP2 and MN1 are simultaneously turned on, and the MP1 and MN2 are simultaneously turned off, thereby supplying a constant current to a positive node 1 and a negative node 2.

A constant voltage is applied across a resistor Rterm by the constant current supplied to the positive node 1 and negative node 2. The constant voltage applied across the resistor Rterm is detected by a comparator 3.

Meanwhile, the related transmitter additionally includes a common-mode feedback circuit to fix a common-mode voltage at a voltage vcom because the common-mode noise at the positive node 1 and negative node 2 is high.

The above-mentioned circuit of the related transmitter has three problems as follows. First, although voltage drop on the resistor Rterm is small, the voltage drop on the NMOS transistor MN1 becomes large due to the on-resistance of the NMOS transistor. Second, the gate capacitance of the PMOS transistor MP1 is charged up to the voltage vcom during the turn-off period, and thus, the threshold voltage of the PMOS transistor MP1 is lowered, which may cause malfunction. Third, the common-mode feedback circuit may not sufficiently fix the common-mode voltage at the voltage vcom due to the parasitic capacitance of the NMOS transistor MN1.

### Section 4: Conclusion

In this lesson, we learned about circuit diagrams and transmitters. We also analyzed a circuit diagram of a transmitter with a push-pull structure and identified some potential issues with the circuit. This knowledge can be applied to design and analyze electronic circuits in various applications.

Lesson: Introduction to Music Theory

### Section 1: Theoretical Concepts

In this section, we will cover some basic concepts in music theory that are essential for understanding how music works.

**Topic 1: Pitch**
Pitch refers to the highness or lowness of a sound. In Western music, the pitch is measured in Hertz (Hz), which represents the frequency of vibration of a sound wave. The standard tuning pitch for most instruments is A4, which means that the frequency of the A note is 440 Hz.

**Topic 2: Rhythm**
Rhythm refers to the pattern of beats in a piece of music. In Western music, the unit of measurement for rhythm is the beat, which is represented by a symbol called a note. The duration of a note determines the length of the beat.

**Topic 3: Melody**
Melody refers to the sequence of musical notes that create a tune. A melody can be composed of different intervals, such as whole steps, half steps, and quarter steps.

**Topic 4: Harmony**
Harmony refers to the combination of two or more notes played simultaneously. These notes are called chords, and they can be major, minor, or other types of chords.

### Section 2: Practical Examples

Now let's look at some practical examples of how these concepts work together in a piece of music.

**Example 1: Pitch**
Listen to the following melody:

```
C D E F G A B C
```

This is the melody of "Twinkle Twinkle Little Star." Notice how each note has a different pitch, creating a pleasant and recognizable tune.

**Example 2: Rhythm**
Listen to the following rhythm:

```
Ta-dum Ta-dum Ta-dum Ta-dum
```

This is the rhythm of Beethoven's "Fur Elise." Notice how the beats are grouped together in a regular pattern, creating a sense of movement and momentum in the music.

**Example 3: Melody**
Listen to the following melody:

```
Do Re Mi Fa So La Ti Do
```

This is the melody of "The Sound of Music." Notice how the intervals between the notes create a catchy and memorable tune.

**Example 4: Harmony**
Listen to the following chord progression:

```
C G Am F
```

This is the chord progression of "Hey Jude" by The Beatles. Notice how the different chords create a sense of tension and release, building up to a powerful and satisfying resolution.

### Section 3: Self-Debating Discussions

In this section, we will engage in self-debating discussions to help us think critically about music theory.

**Question:** Why is it important to understand music theory?

**Answer:** Understanding music theory is important because it helps us to understand how music works. By studying music theory, we can learn how to read and write music, analyze and appreciate the structure of a composition, and communicate effectively with other musicians.

**Question:** How does rhythm relate to melody?

**Answer:** Rhythm and melody are closely related because they are both essential elements of music. Rhythm provides the beat and pulse that drive the music forward, while melody creates the tune and shape of the song. Together, they create a dynamic and engaging musical experience.

**Question:** What is the difference between major and minor chords?

**Answer:** Major and minor chords are two types of chords that create different emotional responses in music. Major chords tend to sound happy and uplifting, while minor chords tend to sound sad and introspective. This is due to the specific intervals and overtones of each chord type.

text: I'm sure that the military has thought about it, but does Bush understand that Iran has some pretty potent allies that may assist Iran if the United States attacks the country?. When Ayatollah Ali Khamenei said that he would retaliate against the U.S. if they attacked, he was not just mouthing off for the exercise... I'm sure that the butthead in the White house knows these things unless he's still not reading the memos given to him, so I would say that bush is counting on some of the other groups coming to aid Iran after we bomb them. That way, " the decider " can attack a few other countries in the name of terrorism and democracy.. What a freakin loser!

Lesson: Understanding International Relations and Diplomacy

Introduction:
International relations and diplomacy are essential aspects of global politics. They involve the interaction between countries and their representatives to maintain peace, promote trade, and protect their interests. In this lesson, we will explore the basics of international relations and diplomacy, including their history, key players, and the importance of communication and negotiation.

Section 1: History of International Relations and Diplomacy

The study of international relations dates back to ancient times when city-states formed alliances for protection and trade. However, modern international relations began in the 17th century with the rise of nation-states and their competition for power and resources. Since then, international relations have evolved through major events such as World War I and II, the Cold War, and the formation of the United Nations.

Diplomacy, on the other hand, has been practiced since ancient times when envoys were sent to communicate with foreign powers. Today, diplomacy involves a range of activities, including negotiations, treaties, and agreements, all aimed at promoting peace and cooperation between countries.

Section 2: Key Players in International Relations and Diplomacy

There are several key players in international relations and diplomacy. These include:

1. Governments: Governments represent their countries in international forums and negotiations.

2. International organizations: Organizations like the United Nations, the European Union, and the World Bank play crucial roles in promoting international cooperation and resolving conflicts.

3. Nongovernmental organizations (NGOs): NGOs are non-profit organizations that work towards specific causes, such as human rights or environmental protection.

4. Multinational corporations: These companies operate globally and have significant influence in international relations.

5. Individuals: Ordinary citizens can also participate in international relations and diplomacy through activism, protests, and petitions.

Section 3: Communication and Negotiation

Effective communication and negotiation are essential skills in international relations and diplomacy. Communication involves listening and understanding different perspectives, while negotiation involves finding common ground and reaching agreements. Both skills require empathy, patience, and critical thinking.

For example, when two countries have a dispute, their representatives must communicate effectively to understand each other's positions. Then, they must negotiate a solution that benefits both parties. This process requires compromise, concessions, and creativity.

Conclusion:
In conclusion, international relations and diplomacy are complex and challenging fields that require knowledge of history, politics, economics, and culture. By understanding the basics of these fields, we can better appreciate the efforts of those who work towards global peace and cooperation. We can also apply these skills to our daily lives, whether in our communities or in our interactions with others.

Lesson Title: Introduction to Deterministic Finite Automata (DFA)

### Section 1: Theoretical Concepts

**Introduction:** A Deterministic Finite Automaton (DFA) is a computational model used in computer science, mathematics, and linguistics to represent a set of strings. It is a finite state machine that accepts/rejects finite strings of symbols and only produces a unique computation (or run) of the automaton for each input string.

**Definition:** A DFA consists of a set of states, an input alphabet, a transition function, and an acceptance condition. The set of states represents the possible configurations of the machine, while the input alphabet represents the set of symbols that can be processed by the machine. The transition function maps each input symbol to a set of next states, and the acceptance condition defines the set of states that represent an accepting path.

**Example:** Let's consider the following language: L = {ba | abna, n > 0}. We can build a DFA to recognize this language by defining the following states: q0 (initial state), q1 (state after processing 'a'), q2 (state after processing 'b'), and q3 (accepting state). The transition function would be defined as follows:

- q0: a -> q1, b -> q2
- q1: a -> q1, b -> q2
- q2: a -> q1, b -> q2
- q3: ε -> q3

In this example, the DFA would accept any string that starts with 'ba' and ends with 'a', regardless of the number of 'a's in between.

### Section 2: Practical Examples

**Building a DFA:** To build a DFA for the language L = {ba | abna, n > 0}, we need to define the initial state, the accepting state, and the transition function. In our example, the initial state is q0, the accepting state is q3, and the transition function is defined as follows:

- q0: a -> q1, b -> q2
- q1: a -> q1, b -> q2
- q2: a -> q1, b -> q2
- q3: ε -> q3

Once the DFA is built, we can test it with various inputs to see if they are accepted or rejected. For example, the string "abbba" would be accepted by the DFA because it starts with 'ba' and ends with 'a', satisfying the acceptance condition.

**Simulating a DFA:** We can simulate a DFA using a software program or an online tool. The simulation would show the current state of the machine, the input symbol being processed, and the next state after processing the input symbol. The simulation would also indicate whether the input string is accepted or rejected by the DFA.

### Section 3: Real-World Scenarios

**Compiling Programs:** DFAs can be used in the compilation of programming languages to detect errors and ensure the correctness of the program. For example, a DFA can be built to recognize legal syntax in a programming language, such as the placement of parentheses in an expression.

**Data Compression:** DFAs can be used in data compression algorithms to reduce the size of text files. By building a DFA that recognizes a specific pattern in the text, we can replace the repeated pattern with a shorter code, resulting in a smaller file size.

### Glossary

- DFA: Deterministic Finite Automaton
- Initial State: The starting state of the DFA
- Accepting State: The state that represents an accepting path
- Transition Function: A mapping of input symbols to sets of next states
- Acceptance Condition: A condition that defines the set of states that represent an accepting path

### Conclusion

In this lesson, we introduced the concept of DFAs, including their definition, components, and practical applications. We also provided examples of building and simulating a DFA and discussed real-world scenarios where DFAs are used. By understanding DFAs, we can appreciate their importance in computer science, mathematics, and linguistics.

Lesson: Introduction to Arduino Programming

## Section 1: Overview of Arduino Programming
Arduino is an open-source platform that allows users to create interactive objects and projects using electronics and software. It is a popular tool for beginners in programming and electronics because it is easy to use and has a large community supporting it. In this lesson, we will introduce you to the basics of Arduino programming and how to get started with your first project.

## Section 2: Setting up your Arduino environment
To start programming with Arduino, you will need to set up your environment. This means installing the Arduino software on your computer and connecting your Arduino board to it. Here are the steps to follow:

1. Download and install the Arduino software from the official website.
2. Connect your Arduino board to your computer using a USB cable.
3. Open the Arduino software and select your board from the list of boards.
4. Check if your board is properly connected by looking at the bottom-left corner of the software.

Once you have set up your environment, you can start writing code and uploading it to your Arduino board.

## Section 3: Writing your first Arduino program
Now that you have set up your environment, let's write our first Arduino program. We will create a simple LED blinking program that turns on an LED connected to a digital pin for one second and then turns it off for one second. Here is the code:

```
void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);
  delay(1000);
  digitalWrite(LED_BUILTIN, LOW);
  delay(1000);
}
```

In this program, we first define the LED pin as an output using `pinMode()`. Then, in the `loop()` function, we turn the LED on using `digitalWrite()` and wait for one second using `delay()`. After that, we turn the LED off and wait for another second.

## Section 4: Uploading your code to your Arduino board
Before uploading your code to your Arduino board, make sure you have connected all the necessary components, such as the LED, resistor, and power source. Then, follow these steps:

1. Click on the "Upload" button in the top-left corner of the Arduino software.
2. Select the correct port and board from the list.
3. Click on the "Browse" button and navigate to the location of your .ino file (usually in the Arduino/samples folder).
4. Click on the "Upload" button again to start the upload process.

If everything is done correctly, you should see the LED blink on and off on your board.

## Section 5: Conclusion
In this lesson, we introduced you to Arduino programming and how to get started with your first project. We covered setting up your environment, writing your first program, and uploading it to your Arduino board. With this knowledge, you can now explore more advanced topics and create your own interactive projects using electronics and software.

text: Style Map. Daily Dispatches From The Global Scene. Continuing its reign over red-carpet beauty looks, the side braid showed up in L.A. last night at the premiere of Letters to Juliet, where the film’s star, Amanda Seyfried, sported a messy, loose, over-the-shoulder incarnation of the increasingly popular style (and worked side-swept bands into the equation, to boot). Here’s where things got a little tricky: Rather than pair the casual coif with natural makeup, Seyfried went with a heavy-handed approach, choosing a very dark black-rimmed eye and a muted brick lip for the occasion. Too much sultry face-painting for such a sweet hairdo? Let us know, below.

text: For the past few years we have had problems with mice or rats digging up and eating the broad beans that we have direct sowed into the market garden, so this year for the first time we are raising our plants in the propagation polytunnel before transplanting them into the field when they are ready. This also gives them a head start against weeds.. We have planted our broad beans into ground from which we've laready harvested leeks this winter. After the leeks we covered the ground with mipex membrane for 2 months, which killed most of the weeds, just needing a few hours top remove the surviving plantain, before planting the beans straight in without any further working of the soil. The leeks had had a top dressing of municipal compost as a mulch, which will also feed the beans. We aim to repeat this process a further two times this spring.

Lesson: How to Grow Broad Beans Successfully
Introduction:
Growing broad beans can be a challenging task due to pests and weeds. However, with the right approach, you can achieve success. In this lesson, we will explore the steps to grow broad beans successfully, from planting to harvesting.
Section 1: Preparing the Soil
- The first step is to prepare the soil by removing weeds and debris.
- If you have previously grown leeks or other crops in the same area, ensure that you remove all traces of them.
- Once the soil is clear, cover it with a layer of mulch to suppress weeds and retain moisture.
- You can use municipal compost as a mulch, which will also provide nutrients to the soil.
Section 2: Planting Broad Beans
- Choose a suitable planting date based on your location and climate.
- Plant the beans directly into the soil, ensuring that they are spaced correctly.
- Use a dibber or a small trowel to make a hole in the soil, then place the bean in the hole and cover it with soil.
- Water the beans thoroughly after planting.
Section 3: Caring for Broad Beans
- Broad beans require regular watering, especially during dry periods.
- Make sure that the soil is not too wet or too dry, as this can affect the growth of the beans.
- Check the plants regularly for pests such as aphids and slugs.
- If you notice any pests, take action immediately to prevent damage to the plants.
Section 4: Harvesting Broad Beans
- Broad beans are ready to harvest when the pods are plump and the beans inside are full-sized.
- Use a knife or scissors to cut the pods off the plant.
- Do not overharvest, as this can affect the yield of the plant.
Conclusion:
Growing broad beans can be a rewarding experience, both in terms of taste and nutrition. By following the steps outlined in this lesson, you can achieve success in growing broad beans. Remember to care for your plants and monitor them for pests, and you will be rewarded with a bountiful harvest.

I. Field of the Invention
The present invention relates generally to elongated support braces which are secured across a plurality of parallel joists in a wall structure to resist the tendency of the wall structure to rack under load, and more particularly, to such a brace which is embedded in aligned narrow channels cut transversely into the front surface of each of the plurality of parallel trusses.
II. Description of the Prior Art
Wall frames are typically constructed by securing a plurality of spaced and parallel vertically extending joists or trusses between horizontally extending beams called plates. Although the joists are secured to the plates, additional strengthening of the structure is necessary in order to resist the tendency of the structure to rack under load such as wind or seismic forces and to increase the load carrying capacity of the structure. Thus, a diagonally extending bracing member is often secured across the parallel joists in order to provide such additional support.
One previously known type of wall construction employed wooden brace members having a let-in construction. This let-in construction is formed by providing a plurality of aligned recesses within the parallel truss members and providing correspondingly spaced recesses in a wooden brace member. In this manner, the wooden brace extends across and between the parallel joists and is secured by fasteners such as nails to each of the joists. Such a construction is not only time consuming to cut and construct, but it also requires that the recesses be sufficiently deep to permit paneling or other surface material to be layed flat against the trusses of the wall structure. Moreover, the removal of sections of the trusses in order to form the appropriate recesses increases the infirmity of the completed structure. In addition, testing of these braces and wall construction indicate that when the wall begins to fail because of racking caused by application of an excessive load, the fasteners pull out of the frame members. Consequently, the brace is pulled apart from the wall structure, whereby the strength of the wall structure is decreased.
One previously known device used to overcome the disadvantages of let-in bracing is the T-shaped metal brace such as the braces disclosed in U.S. Pat. No. 3,875,719. The metal support strip is generally T-shaped with a narrow U-shaped portion forming the base leg of the T. The brace is secured across parallel wooden trusses or joists by embedding the base portion of the strip in aligned saw kerfs extending across the joists. The strips are commonly secured by fasteners such as nails to each of the joists which it crosses. While these previously known metal braces have been found to be advantageous over wood let-in construction, it has also been found that a large number of nails is required to secure the strip to the trusses and to insure that the base remains embedded in the saw kerfs. In addition, these previously known strips and wall constructions have not been designed with regard to the inertial characteristics of the strip about the major and minor axes of the T-shaped configuration. Consequently, the maximum strength and maximum strength per dimension have not previously been realized or utilized in T-shaped metal supports for wood structural elements. Moreover, they are inefficient because they do not make full use of the effects resulting from the connection to the joists.

In recent years, various types of miniature portable electronic devices such as electronic watches, electronic calculators, etc, have come into widespread use. In the case of electronic calculators, the normal arrangement used for input of data such as numerals and symbols is to provide a conventional type of keyboard made up of an number of pushbutton switches, with each switch being used to input a particular numeral, character or symbol. Such an arrangement is convenient for use with a device which is reasonable large in size. However, in the case of a device which is of very small size, such as an electronic wristwatch, the size of the keys and the keyboard must be made extremely small, making the input of data to such a device highly inconvenient. There is therefore a requirement at present for some means of inputting data to a miniature electronic device such as an electronic wristwatch which will not require the use of a keyboard and pushbutton switches, and which will be easy and convenient to use. With the availability of such input means, in conjunction with recent advances in integrated circuit technology, various new facilities could be provided such as, for example, a list of names, telephone numbers, addresses, etc., stored in an electronic wristwatch and easily accessed by the wearer when desired.
The present invention discloses such input means, overcoming the problems of prior art input means such as pushbutton keyboards discussed above. With an input device according to the present invention, a user can input data in the form of patterns representing numerals, characters or symbols, simply by tracing out the shape of each pattern over an array of sensor elements such as touch-sensitive switch electrodes. These sensor elements can conveniently be arrayed over a display surface of the device into which data is input, so that the user can immediately confirm correct input of each pattern, so that for example the sensor elements could be arranged on the upper surface of the watch glass of an electronic wristwatch. It is a particular feature of the present invention that the data input from the sensor elements is interpreted in such a way that only a small number of sensor elements can be used to represent a very large number of different patterns.

To interface a differential pressure sensor with Arduino AMS 5915-0100-D, we need to follow these steps:

1. Connect the sensor to the Arduino board using a 4-wire cable. The red wire is connected to the positive supply, the black wire is connected to the ground, and the yellow wire is connected to the output pin of the sensor.
2. Power the Arduino board using a 9V battery or a power supply.
3. Connect the Arduino board to a computer using a USB cable.
4. Open the Arduino IDE and upload the code to the board.
5. The code reads the sensor data and sends it to the computer over the serial port.
6. The computer receives the data and displays it on the screen.

**Section 3: How to calibrate the sensor?**

Calibration is the process of adjusting the sensor to give accurate readings. To calibrate the AMS5915-0100-D sensor, we need to follow these steps:

1. Connect the sensor to a calibration device that generates a known pressure difference.
2. Adjust the sensor's gain and offset values using the I²C interface.
3. Read the sensor data and compare it with the calibration device's readings.
4. Adjust the gain and offset values until the sensor readings match the calibration device's readings.
5. Save the calibration data for future use.

**Section 4: How to read and interpret the sensor data?**

Once the sensor is calibrated, we can read and interpret the sensor data using the Arduino IDE. The data is displayed in millibars (mbar). Here is an example code:

```
// Initialize the sensor
AMS5915 sensor(0x1E);
// Read the sensor data
float pressure = sensor.readPressure();
// Print the pressure
Serial.print("Pressure: ");
Serial.println(pressure);
```

**Conclusion:**

In this lesson, we learned about interfacing a differential pressure sensor with Arduino AMS 5915-0100-D, calibrating the sensor, and reading and interpreting the sensor data. We covered the theoretical concepts, practical examples, and self-debating discussions to teach critical thinking. We hope you found this lesson informative and useful. Good luck with your projects!

Lesson: Understanding Unfair Labor Practices

**Introduction**

In this lesson, we will learn about unfair labor practices and how they affect workers and their unions. We will cover the following topics:

1. What are unfair labor practices?
2. How do they violate workers' rights?
3. What are some examples of unfair labor practices?
4. What can workers do if they experience unfair labor practices?

**Section 1: What are unfair labor practices?**

Unfair labor practices are actions taken by employers or other individuals that interfere with workers' rights to organize and bargain collectively. These practices are prohibited by law because they undermine the collective bargaining process and harm workers.

**Section 2: How do they violate workers' rights?**

Unfair labor practices violate workers' rights by preventing them from forming unions, bargaining collectively, and improving their working conditions. When employers engage in these practices, they often try to intimidate workers, stop them from joining a union, or punish them for exercising their rights. This undermines the democratic process and the ability of workers to have a voice in the workplace.

**Section 3: What are some examples of unfair labor practices?**

Examples of unfair labor practices include:

- Threatening workers with job loss or other negative consequences for supporting a union
- Spying on workers to gather information about union activities
- Coercing or forcing workers to sign documents withdrawing their support for a union
- Refusing to bargain in good faith with a recognized union
- Discriminating against workers who are involved in union activities

**Section 4: What can workers do if they experience unfair labor practices?**

If workers experience unfair labor practices, they should document the incidents and report them to their union representative or the National Labor Relations Board (NLRB). The NLRB is responsible for enforcing federal labor laws and can investigate complaints of unfair labor practices. If the NLRB finds that an employer has engaged in unfair labor practices, it can order the employer to cease the practices and take other corrective actions.

**Conclusion**

Understanding unfair labor practices is essential for workers and their unions. By knowing their rights and recognizing when those rights are being violated, workers can take action to protect themselves and their colleagues. Through collective action, workers can improve their working conditions and make a positive impact on their communities.

text: How resistance to white-on-black rape launched the Civil Rights movementListen. [REBROADCAST] You know one story about Rosa Parks, but not this one: The woman who gained worldwide fame when she “refused to give up her seat” on a Montgomery bus was also a radical activist and a top NAACP investigator into the routine and ritual rape of black women by white men in the mid-1940s. Rosa Parks’ work on behalf of brutalized black women was part of and helped catalyze one of the more important, but wholly overlooked, building blocks for the American Civil Rights movement. That story is central to DANIELLE McGUIRE’s new book, At the Dark End of the Street: Black Women, Rape, and Resistance – A New History of the Civil Rights Movement from Rosa Parks to the Rise of Black Power..

Lesson: The Importance of Resistance to White-on-Black Rape in the Civil Rights Movement
Introduction:
Resistance to white-on-black rape played a significant role in the Civil Rights movement. This lesson will explore how the fight against this brutal violence helped spark the larger struggle for equality and justice. We will examine the story of Rosa Parks, a prominent figure in the movement, and her work as an investigator for the NAACP. We will also discuss the broader context of sexual violence against black women and how it fueled the Civil Rights movement.
Section 1: The Story of Rosa Parks
Rosa Parks is widely known for her refusal to give up her seat on a Montgomery bus in 1955. However, her work as an activist went far beyond that single act of defiance. In the mid-1940s, Parks was an investigator for the NAACP, working to expose the widespread practice of white-on-black rape in the South. She traveled across the region, documenting cases of sexual violence against black women and girls. This work was dangerous and difficult, but Parks remained committed to exposing the truth and fighting for justice.
Questions:
1. Why was Rosa Parks' work as an investigator for the NAACP important?
2. How did her work relate to the larger struggle for civil rights?
Section 2: The Broader Context of Sexual Violence Against Black Women
Sexual violence against black women was a common occurrence in the South during the mid-20th century. White men often used physical force or threats of violence to coerce black women into sexual relationships. These acts were not only brutal and dehumanizing, but they also served to reinforce the social and economic power imbalances between whites and blacks. The NAACP recognized the importance of addressing this issue and sent Parks and others to investigate these crimes.
Questions:
3. Why was sexual violence against black women a significant issue during the Civil Rights movement?
4. How did the NAACP respond to this issue?
Section 3: The Connection Between Resistance to Rape and the Civil Rights Movement
The fight against white-on-black rape was an important part of the larger struggle for civil rights. By exposing the brutal reality of sexual violence against black women, activists like Rosa Parks helped to shed light on the systemic injustices faced by the black community. This issue also highlighted the need for greater equality and justice, which were central tenets of the Civil Rights movement.
Questions:
5. How did resistance to rape contribute to the Civil Rights movement?
6. What were some of the other key issues addressed by the movement?
Conclusion:
Resistance to white-on-black rape played a crucial role in the Civil Rights movement. Activists like Rosa Parks worked tirelessly to expose the brutal reality of sexual violence against black women and to fight for greater justice and equality. By understanding the connection between these issues, we can better appreciate the complexity and importance of the Civil Rights movement.

Age-dependent loss of accommodative amplitude in rhesus monkeys: an animal model for presbyopia.
The refractive power and axial dimensions of the eye were measured under resting and fully accommodated conditions in 123 caged rhesus monkeys ranging in age from 0.5 to greater than 30 years. The mean resting refraction measured under ketamine anesthesia was -5 diopters. Accommodative amplitude, calculated as the difference between resting refraction and the most negative refraction measured 0.5 to 1 hr after topical application of a maximally effective dose of a cholinomimetic, showed an age-dependent decline. The mean accommodative amplitude of 1- to 5-year-old rhesus monkeys was a remarkable 34 D, while animals over 25 years of age averaged 5 D of accommodation. Some greater than 25-year-old animals showed no measurable change in refraction regardless of the dose or the type of cholinomimetic (carbachol, pilocarpine, or echothiophate) used. The resting axial thickness of the lens was found to increase with age throughout adulthood, well past the end of the growth period. A strong correlation was found between pharmacologically induced change in the refractive power of the eye and change in lenticular thickness. These similarities to the human condition suggest that the rhesus monkey represents a highly suitable animal model for the study of accommodation and presbyopia.

Lesson: Age-dependent Loss of Accommodative Amplitude in Rhesus Monkeys

Introduction:
Accommodation is the process by which our eyes focus on nearby objects. As we age, our ability to accommodate decreases, leading to a condition called presbyopia. In this lesson, we will learn about an animal model for presbyopia, the rhesus monkey, and how their accommodative abilities change with age.

Core Value:
The core value of this lesson is that the accommodative abilities of rhesus monkeys decrease with age, similar to humans. This animal model can be used to study the mechanisms behind presbyopia and develop potential treatments.

Section 1: What is Accommodation?
Accommodation is the process by which our eyes adjust their focus to see objects at different distances. This is done by changing the shape of the lens inside the eye. When we look at a near object, the ciliary muscles contract, causing the lens to become more rounded and increase its refractive power.

Section 2: How does Accommodation Change with Age?
As we age, the lens of our eye becomes less elastic and less able to change shape. This results in a decreased ability to accommodate, making it harder to focus on nearby objects. This condition is called presbyopia.

Section 3: Rhesus Monkeys as an Animal Model for Presbyopia
Rhesus monkeys are a useful animal model for studying presbyopia because their accommodative abilities change with age in a similar way to humans. By studying rhesus monkeys, researchers can gain insights into the mechanisms behind presbyopia and develop potential treatments.

Section 4: Measuring Accommodative Amplitude in Rhesus Monkeys
Researchers have measured the accommodative amplitude of rhesus monkeys ranging in age from 0.5 to greater than 30 years. They found that the mean accommodative amplitude of 1- to 5-year-old rhesus monkeys was a remarkable 34 D, while animals over 25 years of age averaged 5 D of accommodation. Some greater than 25-year-old animals showed no measurable change in refraction regardless of the dose or the type of cholinomimetic (carbachol, pilocarpine, or echothiophate) used.

Section 5: Conclusion
In this lesson, we learned about the age-dependent loss of accommodative amplitude in rhesus monkeys and how this animal model can be used to study presbyopia. We also learned about the mechanisms behind accommodation and how they change with age. By understanding these mechanisms, researchers can develop potential treatments for presbyopia.
