Lesson: Introduction to Research Methods in Psychology

**Objective:** In this lesson, we will learn about the basic principles of conducting research in psychology. We will cover the following topics:

1. Research methods in psychology
2. Types of research designs
3. Data collection and analysis techniques
4. Ethical considerations in research
5. How to read and interpret research articles

**Section 1: Research Methods in Psychology**

Psychology is a scientific discipline that seeks to understand human behavior and mental processes. Research is a critical component of psychology, as it allows us to test hypotheses and theories about human behavior and mental processes. Research methods in psychology involve collecting, analyzing, and interpreting data to answer research questions.

**Section 2: Types of Research Designs**

There are several types of research designs in psychology, including:

1. Experimental design: This design involves manipulating variables to test their effects on participants.
2. Correlational design: This design involves measuring the relationship between two or more variables.
3. Cross-sectional design: This design involves measuring variables at a single point in time.
4. Longitudinal design: This design involves measuring variables over an extended period of time.

**Section 3: Data Collection and Analysis Techniques**

Data collection techniques in psychology include:

1. Surveys: These are questionnaires used to gather information from participants.
2. Interviews: These are structured conversations used to gather information from participants.
3. Observations: These involve observing participants' behavior in natural or controlled settings.
4. Experiments: These involve manipulating variables to test their effects on participants.

Data analysis techniques in psychology include:

1. Descriptive statistics: These involve summarizing and describing the data collected.
2. Inferential statistics: These involve testing hypotheses and drawing conclusions about the data.

**Section 4: Ethical Considerations in Research**

Ethical considerations are essential in psychology research to ensure that participants are not harmed during the research process. Some of the ethical considerations include:

1. Informed consent: Participants must give informed consent before participating in research.

In the Red (TV series)

In the Red is a three-part BBC Two black comedy-crime drama 1998 series featuring Warren Clarke as BBC Reporter George Cragge and Alun Armstrong as Police Superintendent Frank Jefferson, investigating a series of murders of London bank managers, a small political party contesting a by-election, and a plan to overthrow the Director-General of the BBC.

The series was adapted by Malcolm Bradbury from Mark Tavener's novel of the same name (Hutchinson, 1989), which had been inspired by the writer's early experiences working for the BBC and the Liberal Party.

Following the conclusion of the series, the characters of Charles Prentis, played by Stephen Fry, and Martin McCabe, played by John Bird, who also appeared in the radio adaptation of the book (BBC Two, 1995-1999), were featured in their own spin-off series Absolute Power (BBC Radio 4, 2000-2006/BBC Two, 2003-2005), which was also created and written by Tavener.

Lesson: Introduction to Financial Crimes

**Overview:** In this lesson, we will learn about financial crimes and their impact on society. We will explore various types of financial crimes, such as fraud, embezzlement, and money laundering. We will also discuss the role of law enforcement agencies in investigating and prosecuting these crimes.

**Objectives:** By the end of this lesson, students will be able to:

- Define financial crimes and their impact on society.
- Identify various types of financial crimes, including fraud, embezzlement, and money laundering.
- Explain the role of law enforcement agencies in investigating and prosecuting financial crimes.
- Analyze case studies to understand the consequences of financial crimes.

**Section 1: Introduction to Financial Crimes**

Financial crimes are criminal acts that involve the use of financial instruments or systems to commit a crime. These crimes can have a significant impact on society, as they often involve large amounts of money and can harm innocent people. Examples of financial crimes include fraud, embezzlement, and money laundering.

**Section 2: Types of Financial Crimes**

There are several types of financial crimes, including:

1. Fraud: Fraud is a deliberate misrepresentation of the truth made with the intent to deceive another person or organization. It can take many forms, such as credit card fraud, identity theft, and insurance fraud.

2. Embezzlement: Embezzlement is the act of stealing money that has been entrusted to someone else. This can occur in a variety of settings, such as businesses, non-profit organizations, and government agencies.

3. Money laundering: Money laundering is the process of concealing the origins of illegally obtained money to make it appear legal. This is often done by transferring funds through multiple banks and shell companies to obscure the source of the funds.

**Section 3: Law Enforcement Agencies and Financial Crimes**

Law enforcement agencies play a crucial role in investigating and prosecuting financial crimes. These agencies include the Federal Bureau of Investigation (FBI), the Securities and Exchange Commission (SEC), and the Internal Revenue Service (IRS). They work together to identify and stop financial crimes, and to bring perpetrators to justice.

**Section 4: Case Studies**

Let's look at two case studies to see the consequences of financial crimes:

1. Bernie Madoff: Bernard Madoff was a Wall Street financier who ran a massive Ponzi scheme. He defrauded thousands of investors out of billions of dollars, causing many of them to lose their life savings. His actions led to increased regulation of the financial industry and greater scrutiny of investment advisors.

2. Enron: Enron was an energy company that engaged in a variety of financial improprieties, including accounting fraud and insider trading. When the company collapsed in 2001, it caused a significant economic impact and led to increased scrutiny of corporate governance practices.

**Conclusion**

Financial crimes have a significant impact on society, and it is important for law enforcement agencies to investigate and prosecute these crimes. By understanding the different types of financial crimes and their consequences, we can better prepare ourselves to identify and prevent these crimes in the future.

Collaboration and networking are important because they:
- Encourage innovation: When people from different backgrounds and disciplines work together, they bring unique perspectives and ideas to the table. This can lead to new and innovative solutions.
- Provide access to resources: By networking with others, individuals can gain access to resources such as equipment, funding, or expertise that they may not have had access to otherwise.
- Increase visibility: Collaborating with others can increase an individual's visibility within their industry, leading to new opportunities and recognition.
- Build relationships: Networking helps individuals build relationships with others in their field, which can lead to long-term partnerships and support.

Section 3: Practical Examples of Collaboration and Networking
Collaboration and networking can take many forms, such as:
- Working with other artists or creatives on a project: For example, a photographer and a graphic designer could collaborate on a project to create a unique portfolio piece.
- Attending industry events or conferences: These events provide opportunities to meet others in the industry, learn about new trends, and potentially collaborate on future projects.
- Joining professional organizations or online forums: These groups provide a platform for individuals to connect with others in their field, share ideas, and find potential collaborators.
- Reaching out to others in the industry: Even if you don't know someone personally, reaching out via email or social media can lead to new connections and potential collaborations.

Section 4: Critical Thinking and Reflection
As you work on projects and collaborations, it's essential to engage in critical thinking and reflection. Ask yourself questions like:
- What did I learn from this experience?
- How could I have approached this differently?
- What are some areas where I need to improve?
By reflecting on your experiences, you can identify areas for growth and improvement, leading to better collaboration and networking opportunities in the future.

Conclusion:
Collaboration and networking are essential skills in the creative industry. By working together and building relationships with others, individuals can create new opportunities, learn from each other, and grow in their careers. By applying the principles discussed in this lesson, you can become a more effective collaborator and networker, leading to new and exciting opportunities in your creative pursuits.

## Lesson: How to Read a Book Review
### Introduction
 Reading a book review can be a great way to learn about a book before you read it yourself. A good book review can give you insights into the plot, characters, and themes of a book, as well as help you decide whether or not the book is worth reading. In this lesson, we will learn how to read a book review and extract the most important information from it.
### Section 1: Understanding the Structure of a Book Review
A book review typically follows a specific structure, which includes an introduction, body paragraphs, and a conclusion. Here's what each part usually contains:
- **Introduction**: The introduction usually tells you who the reviewer is and what publication they work for. It may also give some background information on the book, such as its genre or author.
- **Body Paragraphs**: The body paragraphs are where the reviewer actually talks about the book. They may discuss the plot, characters, themes, and writing style. Some reviewers may also compare the book to others in the same genre or by the same author.
- **Conclusion**: The conclusion is where the reviewer gives their overall opinion of the book. They may recommend it to others or warn readers away from it, depending on their opinion.
### Section 2: Analyzing the Content of a Book Review
Once you understand the structure of a book review, you can start analyzing the content. Here are some things to look for:
- **Plot Synopsis**: If the review includes a plot synopsis, it can give you an idea of what the book is about without spoiling any surprises.
- **Character Analysis**: If the review includes character analysis, it can help you understand how the characters are developed and how they interact with each other.
- **Thematic Analysis**: If the review includes thematic analysis, it can help you understand what the book is about on a deeper level.
- **Writing Style**: If the review includes comments on the writing style, it can give you an idea of whether the writing is engaging and easy to read or if it's dense and difficult to follow.
- **Comparisons**: If the review includes comparisons to other books or authors, it can help you understand how the book fits into the larger literary landscape.
### Section 3: Applying What You've Learned
Now that you know how to read a book review, you can use this knowledge to make informed decisions about what books to read. Here are some ways to apply what you've learned:
- **Read Reviews Before You Read the Book**: Before you dive into a new book, take a few minutes to read reviews of it. This can help you get a sense of what the book is about and whether it's worth your time.
- **Look for Specific Details**: When reading a review, look for specific details about the plot, characters, and themes. These details can help you get a sense of what the book is about and whether it's something you'll enjoy.
- **Consider Multiple Reviews**: Don't just rely on one review to make your decision. Consider reading multiple reviews from different sources to get a more well-rounded picture of the book.
- **Use Reviews to Expand Your Reading Horizons**: If you're looking for a new book to read, consider using reviews to expand your reading horizons. Look for books that receive positive reviews from critics and readers who have different tastes than you do. This can help you discover new books and genres that you might not have considered otherwise.
### Conclusion
By following the steps outlined in this lesson, you can learn how to read a book review and use that information to make informed decisions about what books to read. Remember to look for specific details, consider multiple reviews, and use reviews to expand your reading horizons. With these skills, you can become a savvy reader and discover new books that you'll love.

Why Do Dogs Like to Shake Hands?

Why do dogs like to shake hands? Let's face it, seeing a dog shake hands is quite an endearing sight and we mostly like it because it makes dogs look smart as if they're adhering to our social etiquette.

Why do dogs like to shake hands? Let's face it, seeing a dog shake hands is quite an endearing sight and we mostly like it because it makes dogs look smart as if they're adhering to our social etiquette. While there's no doubt about the fact that dogs are smart and adept to learning many amazing tricks, their handshaking is a far cry from our ritualistic grasping of one another's hands, accompanied by a brief up and down movement. Yet, dogs seem to sure like to shake hands, so much that some dogs would engage in pawing behaviors almost all day given the opportunity, so what makes dogs so prone to pawing behaviors?

The Human Hand Shake

Human handshakes versus dog handshakes.

Handshaking in human culture traces back to many centuries ago. If we look at ancient archaeological ruins, we can find proof that the practice of shaking hands was already practiced in ancient Greece, as far back as the 5th century BC. The traditional explanation though stems from the Roman times when the handshake was considered a gesture of trust meant to show that the strong right arms were not carrying any weapons, explains English zoologist and ethologist Desmond Morris in his book " The Naked Man: A Study of the Male Body."

Interestingly though, there may be more to that. Recent research now seems to suggest that our handshake ritual makes us closer to dogs than thought. According to a study published by an Israeli team of researchers, our handshake allows transfer of chemical compounds from one person's hands to another. Following the handshake, it was found that both men and women spent time smelling their hands, potential evidence that our sense of smell still plays an important part in our social interactions--quite like dogs, no?

The doggy version of a handshake.

The Dog Handshake

Obviously, in dogs, shaking hands is not the dog's way to say " I don't bear arms" as a dog's main weapons are stored in the mouth and not within the paws. Nor is a dog's handshake a way to greet and meet people as, given the preference, dogs would rather get a good sniff in some other places instead. So why do dogs like to shake hands?

First of all, pawing is a hardwired behavior. While some dog are more "pawsy" than others, dogs tend to use their paws when they want to move something or gain access to something. Training a dog to paw is therefore fairly easy because it encourages a natural, innate behavior. Secondly, pawing often gains a strong history of reinforcement once trained.

A History of Reinforcement

How are dogs trained to shake hands? For the most part through reinforcement, a training method that aims to increase the probability of a behavior to repeat in the future. Most commonly dogs are trained to shake hands by what is known as positive or added reinforcement. Positive reinforcement entails the addition of something immediately following a response for the purpose of increasing the probability of that response to occur across subsequent occasions.

How to train a dog to handshake?

Training a Dog to Shake

A dog is asked to sit and he is shown a treat held in an open hand. The moment the dog sees it, the hand is closed and the dog is allowed to sniff it. Since the dog cannot gain access to the treat, he will feel instinctively compelled to paw at the hand. The moment the dog paws at the hand, the handler says "yes!" or clicks a clicker and the hand is opened so to give the treat. Since most dogs love treats, the addition of the tasty treat will therefore motivate the dog to keep on pawing at the hand.

After several reps, the hand can be kept in the same position, but this time minus the treat, so as soon as the dog paws, the treat is given from the other hand. This is repeated several times. Then, the hand is kept gradually more and more open and the dog is asked to paw at the open hand. At this point, once the dog paws at the open hand fluently, the cue "shake" can be added, right before offering the open hand. After several reps, the treats can stop being given for each and every handshake and can be given on a variable schedule, which means every now and then.

Attention-Seeking Behavior

While treats are a common type of reinforcement added to increase the probability of behaviors, there are other forms of reinforcement that can motivate dogs to shake hands. One of them is attention. Some dogs love and crave attention! To the point that they would do anything that gains it. Social pawing is an easy way for dogs to get attention, either to ask for something they want or to initiate play. People who see the dog trying to shake will likely make happy remarks such as "awww...what a good dog you are!" or will give friendly pats which are reinforcing to attention-seeking dogs who like these types of interactions.

Things Getting Out of Hand

For a good reason, certain trainers are hesitant to train dogs to shake; they hear many dog owners complain that the shaking behavior "gets out of hand" because the dog starts pawing at them or other people repeatedly for attention! This can lead to minor scratches or even more serious skin injuries. How can this type of pawing be discouraged?

There's a good way to prevent a dog's shaking from getting out of hand: bringing it under stimulus control. In other words, this means teaching the dog to shake only when asked to. When the dog complies to the request to shake, the dog is rewarded. Once the shaking behavior is under control of the vocal cue"shake,"any pawing behaviors that occur off cue (that is, without being asked) are either ignored or suppressed by the owner getting up and leaving. This often suffixes to send the dog a clear message: "pawing only works when I am asked for it, if I paw without being asked to, I do not get attention."

Putting Paws to Work

Once a dog learns how to shake, this opens the door to many further training opportunities. Pawing behaviors may lead to other tricks such as high five, salute, wave or paw targeting behaviors that can be useful to train a dog to paw at certain objects, push buttons on and off, file nails by pawing at sandpaper board or even playing a battery-operated piano. The sky's the limit to putting those paws to work, so take advantage of "pawsy" dogs to teach them a vast array of pawsy tricks.

Did you know? Dogs have paw preferences which are similar to the hand preferences seen in human beings. Therefore there are dogs who are mostly left-handed and dogs who are mostly right-handed.

Title: Why Do Dogs Like to Shake Hands?

Lesson Overview:
In this lesson, we will explore the reasons behind why dogs like to shake hands and the differences between human handshakes and dog handshakes. We will also delve into the history of handshakes and their significance in human culture.

Section 1: Introduction

Let's face it, seeing a dog shake hands is quite an endearing sight and we mostly like it because it makes dogs look smart as if they're adhering to our social etiquette. While there's no doubt about the fact that dogs are smart and adept to learning many amazing tricks, their handshaking is a far cry from our ritualistic grasping of one another's hands, accompanied by a brief up and down movement. Yet, dogs seem to sure like to shake hands, so much that some dogs would engage in pawing behaviors almost all day given the opportunity, so what makes dogs so prone to pawing behaviors?

Section 2: Understanding Dog Handshakes

Dog handshakes, also known as pawing, are not the same as human handshakes. In fact, dogs do not grasp the concept of a handshake as humans do. Instead, they use their paws to communicate with other dogs or with their owners. Pawing can be a sign of excitement, anxiety, or even aggression. Dogs may also paw at their owner to get attention or to ask for food or playtime.

Section 3: The History of Handshakes

The origin of the handshake is not entirely clear, but it is believed to have originated from ancient Roman customs. In those days, people would often greet each other by touching noses or foreheads as a sign of respect. Over time, this gesture evolved into the modern-day handshake. Today, handshakes are a common way to greet someone or seal a business deal.

Section 4: Conclusion

In conclusion, while dogs may not fully understand the concept of a handshake, they still enjoy pawing behaviors as a way to communicate with others. Understanding the history of handshakes can help us appreciate the significance of this cultural custom and its evolution over time. Whether you're a dog lover or not, it's hard not to smile when you see a dog shaking hands!

Glossary:
- Handshake: A customary greeting or agreement between two people where they grasp each other's hands and move them up and down.
- Pawing: The act of using one's paw to communicate or interact with others.
- Aggression: Behavior that is intended to harm or intimidate others.
- Communicate: To share information or ideas with someone else.
- Custom: A traditional or habitual practice or behavior.

Self-Debate Discussion:

Do you think that dogs understand the concept of a handshake or is it just a way for them to communicate with others? How does the history of handshakes impact our understanding of this cultural custom today?

The Obama administration is moving ahead with a key part of its climate regulations despite the rules being placed on hold by the Supreme Court.

The Environmental Protection Agency issued a proposal Thursday detailing a Clean Energy Incentive Program meant to drive states' adoption of renewable energy to meet the demands of the agency's far-reaching Clean Power Plan, which is being challenged in federal appeals court by more than two dozen states and dozens of other groups.

"Today's proposal will help guide states and tribes that choose to participate in the program when the Clean Power Plan becomes effective," the EPA said in announcing the clean energy proposal.

EPA acting assistant administrator Janet McCabe said the agency has been working on the program for almost a year and Thursday's proposal "keeps that conversation moving forward."

"Taking these steps will help cut carbon pollution by encouraging investment in renewable energy and energy efficiency, which will help give our kids and grandkids a healthier and safer future," McCabe said.

The EPA wants states, industry and others to comment on the proposal so they can get the incentive program right once the Clean Power Plan goes into effect.

The Supreme Court has halted the plan until the merits of the case against it have been heard in appeals court in late September.

The EPA climate plan directs states to cut greenhouse gas emissions, which many scientists blame for driving climate change, by one-third by 2030. States and dozens of industry groups opposing the rule say it far surpasses EPA's authority to implement it and is illegal.

The EPA has said it is confident the plan will hold up under court review and it will triumph in the end.

Lesson: Introduction to Renewable Energy

### Section 1: What is Renewable Energy?

Renewable energy is a type of energy that comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are replenished at a faster rate than they are used up. It is an alternative to traditional sources of energy like coal, oil, and gas, which are finite and can run out.

### Section 2: Why is Renewable Energy Important?

Renewable energy is important because it reduces our dependence on fossil fuels, which are the main contributor to air pollution and climate change. By using renewable energy sources, we can reduce greenhouse gas emissions and mitigate the effects of global warming. Additionally, renewable energy is sustainable and can help create jobs in the clean energy sector.

### Section 3: Types of Renewable Energy

There are several types of renewable energy, including:

1. Solar energy: This type of energy is harnessed from the sun using solar panels.
2. Wind energy: This type of energy is generated by wind turbines that convert the kinetic energy of the wind into electricity.
3. Hydroelectric energy: This type of energy is produced by dams that use the force of falling water to generate electricity.
4. Geothermal energy: This type of energy is derived from the heat within the Earth and can be used to produce electricity or heat buildings.
5. Biomass energy: This type of energy is generated from organic matter such as wood, crops, and manure, which is burned to produce heat or electricity.

### Section 4: How does Renewable Energy Work?

Renewable energy works by converting the natural energy sources mentioned above into usable forms of energy. For example, solar panels absorb sunlight and convert it into electricity, while wind turbines use the kinetic energy of the wind to generate electricity. Hydroelectric dams use the force of falling water to generate electricity, and geothermal power plants use the heat within the Earth to produce electricity or heat buildings.

### Section 5: Real-World Examples

Real-world examples of renewable energy include:

1. Solar panels on rooftops that generate electricity for homes and businesses.
2. Wind turbines that provide electricity to communities.

Loch Eck

Loch Eck; (Gaelic: Loch Eich) is a freshwater loch located on the Cowal peninsula, north of Dunoon, Argyll and Bute, Scotland. It is  long. Apart from Loch Lomond, it is the only naturally occurring habitat of the Powan (fish). Besides powan, the loch also has salmon, sea trout, brown trout and arctic charr.

Loch Eck is within the Argyll Forest Park which, is itself part of the Loch Lomond and The Trossachs National Park. It is close to the Benmore Botanic Garden and the Benmore Outdoor Centre, which uses the loch and its surrounding for outdoor learning.

A pathway runs along the west side of the loch, and gives access to the Paper Caves, set in the steep hillside with caving access to a platform set above a steep scarp within the cave. A legend holds that the Argyll family documents were hidden in the caves when the 9th Earl of Argyll was arrested, to prevent his lands from being made forfeit.

The loch is also an impounding reservoir with a concrete dam measuring  high. The dam was completed in 1973.  Loch Eck now supplies the freshwater to much of the southeast of Cowal, including Dunoon.

In July 2013, two dogs died due to algal bloom present in the loch. Warnings were then posted advising that people and animals should avoid contact with the water. A similar incident occurred again in June 2019.

Lesson: Introduction to Freshwater Lochs

## Section 1: What are Freshwater Lochs?

Freshwater lochs are bodies of water found in Scotland and other parts of the world. They are similar to lakes but are usually longer and narrower. Freshwater lochs are an important part of the ecosystem and provide habitats for many different types of animals and plants.

## Section 2: What Makes Freshwater Lochs Unique?

One of the unique features of freshwater lochs is the presence of powan, a type of fish that can only be found in these lochs. Other types of fish, such as salmon, sea trout, brown trout, and arctic charr, can also be found in freshwater lochs.

## Section 3: Why are Freshwater Lochs Important?

Freshwater lochs are important because they provide habitats for many different types of animals and plants. They also play a crucial role in the ecosystem by filtering pollutants and providing clean water for other organisms to drink.

## Section 4: How do Freshwater Lochs Impact the Environment?

Freshwater lochs can have a significant impact on the environment. For example, if there is too much nutrient runoff from agricultural land or other sources, this can lead to an overgrowth of algae in the loch. This can be dangerous for animals that live in the water, such as fish, and even for humans who swim in the loch.

## Section 5: Conclusion

Freshwater lochs are an important part of the ecosystem and provide habitats for many different types of animals and plants. By understanding the unique features of these lochs and their impact on the environment, we can work to protect and preserve them for future generations.

Ubiquitin ligases in cancer: ushers for degradation.
The regulated degradation of cellular proteins by the ubiquitin-proteasome system impacts a range of vital cellular processes in both normal and cancerous cells. An ubiquitin-activating enzyme (E1), ubiquitin-conjugating enzyme (E2), and ubiquitin ligase (E3) catalyzes the conjugation of the protein ubiquitin to a target protein and, thereby, tags that protein for recognition and destruction by the proteasome. Ubiquitin ligases are particularly interesting because they determine substrate selection. This review examines the role of dysregulated ubiquitin ligase activity in the development and progression of various cancers, and highlights why ubiquitin ligases have emerged as extremely attractive targets for therapeutic intervention in a number of human malignancies.

Lesson: Understanding the Ubiquitin-Proteasome System in Cancer

Introduction:
The ubiquitin-proteasome system is a crucial cellular process responsible for the degradation of proteins. It plays a significant role in maintaining cellular homeostasis and regulating various cellular processes, including cell cycle progression, signal transduction, and gene expression. In cancer cells, the dysregulation of this system can contribute to uncontrolled cell growth and proliferation. In this lesson, we will explore the role of ubiquitin ligases in cancer and their potential as therapeutic targets.

Section 1: The Ubiquitin-Proteasome System

1.1 What is the Ubiquitin-Proteasome System?
The ubiquitin-proteasome system is a highly regulated and conserved cellular pathway responsible for the selective degradation of proteins. It involves two main components: the ubiquitin ligase complex (E1, E2, and E3) and the proteasome. The E1 enzyme activates ubiquitin, which is then transferred to the E2 enzyme. The E3 enzyme recognizes specific target proteins and transfers ubiquitin to them. Finally, the 26S proteasome degrades the ubiquitinated proteins into small peptides.

1.2 Importance of the Ubiquitin-Proteasome System in Cancer
The ubiquitin-proteasome system plays a critical role in controlling cellular processes such as cell cycle progression, signal transduction, and gene expression. Dysregulation of this system can lead to uncontrolled cell growth and proliferation, which is a hallmark of cancer. Additionally, the degradation of tumor suppressor proteins and the stabilization of oncogenic proteins can contribute to cancer development and progression.

Section 2: Ubiquitin Ligases in Cancer

2.1 Role of Ubiquitin Ligases in Cancer
Ubiquitin ligases are enzymes that catalyze the transfer of ubiquitin from the E2 enzyme to the target protein. They play a crucial role in determining substrate selection and are involved in various cellular processes. In cancer cells, dysregulated ubiquitin ligase activity can lead to the stabilization of oncogenic proteins and the degradation of tumor suppressor proteins, promoting cancer development and progression.

2.2 Examples of Dysregulated Ubiquitin Ligases in Cancer
Some examples of dysregulated ubiquitin ligases in cancer include the following:

- RING finger protein 5 (RNF5): Overexpressed in several types of cancer, RNF5 promotes cell survival by stabilizing oncogenic proteins and destabilizing tumor suppressor proteins.
- Breast cancer-associated protein 1 (BCL10): Dysregulated in multiple myeloma, BCL10 promotes cell survival by stabilizing the anti-apoptotic protein Bcl-2.
- The E3 ubiquitin ligase-associated protein 1 (ELAVL1): Overexpressed in several cancers, ELAVL1 promotes cell survival by stabilizing oncogenic proteins.

Section 3: Therapeutic Targeting of Ubiquitin Ligases in Cancer

3.1 Potential of Targeting Ubiquitin Ligases in Cancer Therapy
Targeting ubiquitin ligases has emerged as an attractive strategy for cancer therapy due to their critical role in cancer development and progression. Inhibiting ubiquitin ligases can potentially restore the normal degradation of oncogenic and tumor suppressor proteins, leading to cancer cell death.

3.2 Challenges in Targeting Ubiquitin Ligases
Despite the potential of targeting ubiquitin ligases in cancer therapy, there are several challenges:

- Identifying specific ubiquitin ligases that are dysregulated in a particular cancer type
- Developing selective inhibitors that can specifically target the desired ubiquitin ligase without affecting other ubiquitin ligases or cellular processes
- Overcoming potential off-target effects and toxicity issues

Conclusion:
Understanding the role of ubiquitin ligases in cancer and their potential as therapeutic targets is crucial for developing novel cancer therapies. While there are challenges in targeting ubiquitin ligases, advances in molecular biology and drug discovery may help overcome these challenges and pave the way for more effective cancer treatments.

New insights into diabetic retinopathy by OCT angiography.
Diabetic retinopathy (DR) is one of the most common diabetic complications, which has become a leading cause for vision loss, mainly because of macular edema and vitreous hemorrhage. Optical coherence tomography (OCT) angiography is a novel technique to visualize vascular changes including microaneurysm, non-perfusion area, intraretinal microvascular abnormalities, and neovascularization. Recently, it is possible to quantify vascular density, foveal avascular zone area, non-perfusion area objectively using OCT angiography. In addition, OCT angiography also provides an alternative method to evaluate the effect of anti-vascular endothelial growth factor (VEGF) treatments by providing high resolution images of macular microcirculatory abnormalities. Thus OCT angiography is an effective method to investigate the vascular changes of the disease, and can also be potentially applied in the diagnosis, treatment, and follow up of DR.

Lesson: Introduction to Cycling Safety

### Section 1: Theoretical Concepts

Cycling safety is an essential aspect of cycling that every cyclist should be aware of. It involves understanding the rules of the road, being visible to other road users, and taking necessary precautions to avoid accidents. In this lesson, we will explore the various aspects of cycling safety and how to apply them in real-world scenarios.

### Section 2: Practical Examples and Real-World Scenarios

Let's consider a scenario where a cyclist is riding on a busy road. The cyclist is wearing dark clothing and has no lights on their bike. As the cyclist approaches an intersection, they notice a car approaching from the opposite direction but do not see the car until it is too late. The car driver did not see the cyclist until the last moment and had to swerve to avoid a collision. This scenario illustrates the importance of being visible while cycling. The cyclist could have avoided the near-miss by wearing bright or reflective clothing and having lights on their bike.

Another scenario involves a group of cyclists riding in a pack. One of the cyclists swerves to avoid a pothole, but the cyclist behind them does not see the pothole and crashes into the back of the first cyclist. This scenario highlights the importance of maintaining a safe distance from other cyclists and being aware of the road conditions.

### Section 3: Self-Debating Discussions

1. Why is it essential for cyclists to be visible while cycling?
Answer: Being visible while cycling increases the chances of being seen by other road users, reducing the risk of accidents. Wearing bright or reflective clothing and having lights on your bike make you more visible to motorists, especially in low-light conditions.

2. What are some ways to maintain a safe distance from other cyclists?
Answer: Maintaining a safe distance from other cyclists involves keeping a few bike lengths between you and the cyclist in front of you. This allows enough space for the cyclist to react to any sudden changes in the road conditions or other hazards. Additionally, communicating with other cyclists using hand signals can help prevent accidents.

### Glossary
- Road conditions: The current state of the road surface, including potholes, gravel, or debris.
- Reflective clothing: Clothing that reflects light, making the wearer more visible to other road users.
- Safe distance: The amount of space between two cyclists or between a cyclist and a vehicle.

### Conclusion

In conclusion, cycling safety is crucial for every cyclist to follow. By being visible, maintaining a safe distance from other cyclists, and being aware of the road conditions, cyclists can significantly reduce the risk of accidents. This lesson has provided practical examples and real-world scenarios to illustrate these concepts. Applying these skills to new problems will help you become a safer and more responsible cyclist.

text: The UK Government is introducing a Plastic Packaging tax in April 2022. The tax will apply to plastic packaging manufactured in, or imported into the UK where the plastic used in its manufacture contains less than 30% recycled plastic. It hopes it will encourage customers to buy plastic with a percentage of recycled content in it; thus encouraging better collection of plastic waste and more recycling. The more the recycled content in the plastic the less ‘perfect’ the film and print are, however over time it will likely become the ‘norm’ and everyone will accept this is a step we all have to take and a compromise we all have to make; for sustainability of the planet and the environment..

Many outsiders consider bookbinding and printmaking historically to be a man’s craft. Fortunately, modern times show us how many wonderful female artists are there in the world. But that’s also worth knowing there were female printmakers in the early era of the craft — in the late 15th century.. Collection of Henrietta Louisa Koenen was gathered between 1848 and 1861, and consists of many wonderful examples of work of female printers from the 16th to the 19th centuries.. Collection is exhibited for the first time since 1901. The exhibition ends on January 31st, 2016.. Please find more information on the New York Public Library!

Lesson: Women in Printmaking

Introduction:
Printmaking is an art form that involves creating images on a surface, usually paper or fabric. It has been practiced for centuries, and while it is often associated with male artists, there have been many talented female printmakers throughout history. In this lesson, we will explore the contributions of women to the field of printmaking and learn about some of the challenges they faced.

Section 1: Early Female Printmakers
In the early days of printmaking, women were not always welcome in the industry. However, there were some notable exceptions. For example, the German artist Katherine Motschmann produced a series of woodcuts in the late 15th century. These prints depicted scenes from everyday life and were highly regarded by her contemporaries.

Section 2: Henrietta Louisa Koenen's Collection
In the mid-19th century, a Dutch woman named Henrietta Louisa Koenen began collecting prints by female artists. Her collection included works by artists from the 16th to the 19th centuries, and it was one of the largest collections of its kind. Unfortunately, much of the collection was lost or damaged over time, but what remains is still a valuable resource for scholars today.

Section 3: Challenges Faced by Female Printmakers
While there have been many talented female printmakers throughout history, they often faced significant challenges. For example, they may have had difficulty gaining access to the same resources as male artists, such as printing equipment or training. Additionally, they may have struggled to be taken seriously by their peers or the general public. Despite these obstacles, many women persisted in their craft and produced beautiful and thought-provoking work.

Section 4: Modern Female Printmakers
Today, there are many successful female printmakers working in the field. These artists use a variety of techniques, including etching, lithography, and screenprinting, to create stunning works of art. Some well-known contemporary female printmakers include Kiki Smith, Ed Ruscha, and Yoko Ono.

Conclusion:
In conclusion, we have explored the contributions of women to the field of printmaking. From early pioneers like Katherine Motschmann to modern masters like Kiki Smith, female artists have made significant contributions to this art form. While they faced many challenges along the way, their perseverance and talent have left a lasting impact on the world of art. By studying the work of these women, we can gain a deeper appreciation for the rich history of printmaking and be inspired to continue pushing boundaries in our own creative pursuits.

Photoshop CS5: If I only wish to select the black portion of the below image (to create a layer mask with it), how would I do so? It was generated by clicking "Make Selection" from a vector shape that's made up of several paths (each of the triangles, then the rectangle that encloses them). Thank you in advance!

As a related follow-up, how do I add to a selection? i.e. If I make one selection, how do I keep adding more parts to it? Necessary to use paths?

The answers are good and its a good question but for your particular problem why not just open it in illustrator and add a stroke and remove the fill. Since you already have it in vector that would be the best result

Hi Horatio. This is really useful, thank you, but two more q's based on it: 1. Is there a way to see which parts of a multiple-shape selection are "added" vs. "subtracted," i.e. Selected vs. removed from the selection? Also, 2. With my example above, this is a selection made from a workpath, so I'm not sure how the above would apply, as I am not making the selection from scratch... Is there a way to do it here?
–
zakgottliebJan 31 '13 at 12:21

It is worth experimenting, but the ability to add and remove is tool based. You can easily switch tools without destroying the selection. If you need to break it into steps to get your head around, you can select a part you want to remove, create a temp layer, flood it with black and hide it. Deselect, make a new selection, and then ctrl+shift+click the icon of the temp layer to subtract the temp layer. etc. etc.

Once selected, consider the selection itself an object which can be worked on.
–
horatioJan 31 '13 at 14:58

I'm sorry - I understand the suggestion, but does that mean this method is not possible if a selection already exists from a work path? To be clear, I already have the above selection from the vector shape - i do not wish to make another one - but I simply wish the parts in black to be selected, and nothing else... I'm not sure how to accomplish this based on your suggestion.

zakgottliebJan 31 '13 at 17:26

When you choose a Selection tool (Marquee, Lasoo, Quick Selection tool)
you will find options for adding/substracting/intersecting with an existing selection in the Tool Options Bar(up).

Screenshot 1:
Screenshot 2:
In this screenshot I am first(#1) creating a simple sqare selection with the "New selection" option of the "Rectangular Marquee Tool".

After I have the existing selection I am substracting a part from it using the "Substract from selection" option of the "Rectangular Marquee Tool".

I hope this clears any confusion about my answer. Good luck!

UPDATE - 25/02/2013**:
What the asker, Zak833 is actually looking for is something like the Pathfinder Tool in Illustrator, but for selections not for Shapes... he is trying to use the Selection Tool in a matter that the Shape Tool usually works,

A kind of workaround:
First work with the shapes you are trying to alter then recreate the selection from the shape.
Since Photoshop CS6 there are some simmilar options when creating a new shape(see screenshot). So your workaround here would be something like this:
Again, first alter/modify your shape then remake your selection from that new modified Shape.

Thanks, Flavius. I understood his answer well, but the primary question is how to do this with sections of a pre-existing selection, such as the one above? I made this selection from a work path, but now I just wish to isolate the black sections. One answerer suggested Select -> Color Range, which I will probably do, but I was wanting to know if there was a way to do it with a similar method to the one outlined by horatio or yourself....
–
zakgottliebFeb 1 '13 at 11:16

you use the "substract" option from the above mentioned and you take out what ever is extra in order to isolate the black sections... maybe I don't understand correctly what you are trying to achieve... I'll think about it
–
Flavius FrantzFeb 1 '13 at 11:53

I guess I'm not explaining it well. That suggestion you just made would involve making a NEW selection in order to subtract... What if I wish to "select" part of the selection that has ALREADY been made and tell it to subtract from the selection behind it? i.e. If I did not want to alter the shape of the already-made selections, but still wanted one of them to subtract from another? Does it make more sense now?
–
zakgottliebFeb 1 '13 at 16:40

OK. What you and horatio have suggested is great for controlling selection areas when you have not already got a selection in front of you to begin with. In the case that I've shown with the envelope, it is a selection that was made from a work path. I am looking to add/subtract parts of this already-existing group of selections from other parts in the group, rather than priming the selection tool to add or subtract in the way that yourself and horatio have suggested. The selections are already there, so how do I configure one of them to subtract from another, for example?

Lesson: Understanding Marine Biodiversity and Conservation

## Section 1: Introduction to Marine Biodiversity

Marine biodiversity refers to the variety of living organisms in the ocean, including plants, animals, and microbes. It plays a crucial role in maintaining the health of our planet and supports many human activities, such as fishing, tourism, and research. However, marine biodiversity is facing several threats, including climate change, pollution, overfishing, and habitat destruction. In this lesson, we will learn about the importance of marine biodiversity, its types, and the factors affecting it.

## Section 2: Understanding Marine Biodiversity

There are three main types of marine biodiversity: species diversity, genetic diversity, and ecosystem diversity. Species diversity refers to the variety of different species living in the ocean, while genetic diversity refers to the genetic differences within a species. Ecosystem diversity refers to the variety of different habitats and ecological processes in the ocean.

Marine biodiversity can be affected by several factors, including natural processes and human activities. Natural processes that affect marine biodiversity include changes in ocean currents, temperature, and nutrient availability. Human activities that affect marine biodiversity include overfishing, pollution, coastal development, and climate change.

## Section 3: Conservation of Marine Biodiversity

Conservation of marine biodiversity is essential to ensure the long-term health of our oceans and the many services they provide to humans. There are several ways to conserve marine biodiversity, including protecting important habitats, reducing pollution, regulating fishing practices, and promoting sustainable tourism.

One effective way to conserve marine biodiversity is through the establishment of marine protected areas (MPAs). MPAs are areas of the ocean where human activities, such as fishing and coastal development, are restricted to allow marine life to recover and thrive. Another way to conserve marine biodiversity is through the reduction of pollution, such as plastic waste, which harms marine life and habitats.

## Glossary

- Biodiversity: The variety of living organisms in a specific area or on Earth as a whole
- Habitat: The natural environment in which an organism lives, grows, and reproduces
- Ecosystem: A complex community of living and nonliving things interacting with each other in a specific environment
- Overfishing: The excessive harvesting of fish from a body of water
- Pollution: The introduction of harmful materials into the environment
- Sustainable: Able to be maintained at a certain rate or level

## Conclusion

In conclusion, understanding and conserving marine biodiversity is crucial for the long-term health of our planet. By learning about the different types of marine biodiversity and the factors affecting them, we can take steps to protect and preserve this valuable resource. By applying the knowledge gained from this lesson, we can contribute to the conservation of marine biodiversity and promote sustainable practices.

Lesson: Introduction to Earth's History

## Section 1: Theoretical Concepts
Earth's history refers to the entire timeline of events that have occurred on our planet since its formation. It is divided into several periods, including the Precambrian, Paleozoic, Mesozoic, and Cenozoic eras. Each era is further divided into periods, epochs, and ages based on significant geological and biological events.

## Section 2: Questions and Answers
1. What is Earth's history?
2. How is Earth's history divided?
3. What are the significant events that mark the divisions in Earth's history?

## Section 3: Definitions of Purpose
The study of Earth's history is essential for understanding the evolution of life on our planet, the changes in the environment, and the factors that have shaped human civilization. It also helps us appreciate the natural processes that have led to the current state of our planet and the challenges we face today.

## Practical Examples Using Mathematical Abstractions and Real-World Scenarios
Consider the following example: During the Paleozoic era, there was a significant increase in the diversification of plant life. This led to the development of extensive forests, which in turn contributed to the rise of oxygen levels in the atmosphere. This increase in oxygen levels allowed for the evolution of more complex life forms, including insects and eventually, dinosaurs.

## Glossary
- Precambrian: The earliest part of Earth's history, before the appearance of multicellular life.
- Paleozoic: The era of Earth's history from about 540 to 250 million years ago, characterized by the emergence of diverse plant and animal life.
- Mesozoic: The era of Earth's history from about 250 to 65 million years ago, marked by the rise of dinosaurs and the first mammals.
- Cenozoic: The era of Earth's history from about 65 million years ago to the present day, characterized by the evolution of modern plants and animals.

## Conclusion
Understanding Earth's history is crucial for appreciating the natural processes that have shaped our planet and the challenges we face today. By studying the events of the past, we can better understand the present and make informed decisions about the future.
