Chronic ethanol ingestion during puberty alters the transient increase in testicular 5 alpha-reductase in the Swiss-Webster mouse.
Previous experiments with inbred mice showed that chronic ethanol treatment delays male pubertal development. An initial event in sexual maturation in the rat is a transient increase in 5 alpha-reductase. The present study was conducted to determine whether similar ethanol effects occur in outbred mice (Swiss-Webster), to determine the ontological profile of testicular 5 alpha-reductase in the mouse, and to evaluate the effect of ethanol treatment on this enzyme. After 29 days of treatment with a liquid diet (beginning at age 20 days), reductions in the ethanol-treated mice as compared with the controls were noted in testicular weight (55.0 +/- 2.0 vs. 63.0 +/- 2.4 mg; P less than 0.01), epididymal sperm content (6.8 X 10(5) vs. 14.4 X 10(5); P less than 0.05), and sperm motility (45% vs. 57%; P less than 0.05). After 43 days, differences no longer existed. In chow-fed mice, a substantial rise in 5 alpha-reductase (1 unit = 1 pmole DHT formed/45 min/mg testis) began at age 24 days. Activity peaked at approximately 65 units at 25 to 30 days and gradually declined to 6.4 +/- 0.8 units at 63 days. After 29 days treatment, 5 alpha-reductase of the pair-fed control group was 26.8 +/- 4.9 units, which decreased to a baseline value of 7.0 +/- 2.1 units after 43 days treatment. In contrast, 5 alpha-reductase of the ethanol-treated group remained at baseline levels after 29 days (7.7 +/- 2.3 units) and 43 days of treatment (7.6 +/- 2.3 units).(ABSTRACT TRUNCATED AT 250 WORDS)

Lesson Title: The Effects of Chronic Ethanol Ingestion on Testicular 5 Alpha-Reductase in Mice

Introduction:
In this lesson, we will learn about a study that investigates the effects of chronic ethanol ingestion on testicular 5 alpha-reductase in mice. We will cover the background information, the experimental design, the results, and the implications of the study. By the end of this lesson, you will be able to understand the impact of ethanol on the development of mice and the role of 5 alpha-reductase in their reproductive system.

Background Information:
Testicular 5 alpha-reductase is an enzyme that plays a crucial role in the development of the male reproductive system. It converts testosterone to dihydrotestosterone (DHT), which is responsible for the development of male secondary sexual characteristics. In mammals, the activity of 5 alpha-reductase increases during puberty, leading to the development of male reproductive organs and the production of sperm.

Ethanol is a toxic substance that can have detrimental effects on the developing organism. Previous studies have shown that chronic ethanol treatment delays male pubertal development in inbred mice. However, it is not known whether similar effects occur in outbred mice (Swiss-Webster). Therefore, the present study aimed to determine the effects of chronic ethanol ingestion on testicular 5 alpha-reductase in Swiss-Webster mice and to evaluate the ontological profile of this enzyme in the mouse.

Experimental Design:
The experiment was conducted using Swiss-Webster mice. The mice were divided into two groups: control group and ethanol-treated group. The control group received a standard laboratory diet, while the ethanol-treated group received a liquid diet containing ethanol for 29 days, starting at age 20 days. After the treatment period, the researchers measured various parameters, including testicular weight, epididymal sperm content, and sperm motility.

Results:
The results showed that chronic ethanol ingestion significantly reduced testicular weight, epididymal sperm content, and sperm motility in the ethanol-treated mice compared to the control group. These effects were observed after 29 days of treatment and persisted until 43 days. However, by 43 days, the differences between the two groups had disappeared. The researchers also found that the activity of testicular 5 alpha-reductase peaked at approximately 65 units at 25 to 30 days and gradually declined thereafter.

Implications:
The results of this study suggest that chronic ethanol ingestion can negatively affect the development of the male reproductive system in mice. The reduction in testicular weight, epididymal sperm content, and sperm motility may be due to the inhibition of 5 alpha-reductase by ethanol. This finding has important implications for understanding the effects of alcohol on human reproductive health.

Conclusion:
In conclusion, chronic ethanol ingestion can alter the transient increase in testicular 5 alpha-reductase in Swiss-Webster mice. This finding has important implications for understanding the effects of alcohol on the development of the male reproductive system in mammals. By learning about the effects of ethanol on 5 alpha-reductase, we can better understand the mechanisms underlying the development of male reproductive organs and the production of sperm. This knowledge can be applied to develop strategies to prevent or mitigate the negative effects of alcohol on reproductive health.

Advanced search operators are words or symbols that you can use to refine your search. For example, you can use the "AND" operator to combine two keywords, or the "OR" operator to find synonyms.

**Topic 4: Evaluating Search Results**
Once you have entered your keywords, the search engine will display a list of web pages that are relevant to your query. You should evaluate each web page to determine if it is a reliable source of information.

**Section 2: Directories and Databases**
While search engines are useful for finding general information, there are times when you need more specific information. In this section, we will learn about directories and databases that provide specialized information.

**Topic 1: Understanding Directories and Databases**
Directories and databases are collections of information that are organized in a specific way. Unlike search engines, which use algorithms to rank web pages, directories and databases use categories and tags to organize information.

**Topic 2: Finding Directories and Databases**
There are many directories and databases available, such as Wikipedia, the World Factbook, and the United States Census Bureau. You can find these resources by searching for them on a search engine or by visiting a library.

**Topic 3: Evaluating Directories and Databases**
Like web pages, directories and databases should be evaluated to determine if they are reliable sources of information. You should look for authorship, date of publication, and peer review.

**Section 3: Social Media**
Social media is another way to find information online. In this section, we will learn how to use social media effectively.

**Topic 1: Understanding Social Media**
Social media is a platform where people can share information and communicate with each other. There are many social media platforms available, such as Facebook, Twitter, and LinkedIn.

**Topic 2: Finding Information on Social Media**
You can find information on social media by searching for hashtags, joining groups, or following people who are knowledgeable about your topic.

**Topic 3: Evaluating Information on Social Media**
Just because information is on social media does not mean it is true. You should still evaluate the information to determine if it is reliable.

**Conclusion:**
In this lesson, we learned how to find information online using search engines, directories and databases, and social media. By understanding how to use these resources effectively, we can find the information we need quickly and easily.

text: Water releases from Gavins Point Dam on the Missouri River in southeast South Dakota are being halted for about eight hours so officials can inspect spillway damage caused by high water releases during last summer's flooding.. The Army Corps of Engineers and the National Park Service are advising people to use caution Wednesday. The river level is forecast to drop eight feet at Yankton and by a similar amount downstream, and flow levels could change without notice.. Boat ramps and sections of the river might become inaccessible to boats, and officials say people walking on sandbars should be aware that water levels could change quickly.. Officials also say cultural artifacts might surface, and they're reminding the public that federal law prohibits collecting them.

Lesson: Understanding the Missouri River Flooding

**Introduction:** In this lesson, we will learn about the Missouri River flooding and its impact on the surrounding areas. We will discuss the causes of the flooding, the measures taken to prevent it, and the consequences of the flood.

**Section 1: Understanding the Causes of Flooding**

- What is flooding?
Flooding occurs when water overflows its normal boundaries, such as rivers, lakes, or coastal areas, and submerges land that is usually dry.

- What causes flooding?
Flooding can occur due to several reasons, including heavy rainfall, melting snow or ice, high tides, or even human activities like damming a river. In the case of the Missouri River, flooding is caused by heavy rainfall and snowmelt in the upper basin of the river.

- Why is it important to understand the causes of flooding?
Understanding the causes of flooding helps us predict and prepare for future floods. It also enables us to take necessary precautions to minimize their impact.

**Section 2: Preventing Flooding**

- What measures can be taken to prevent flooding?
There are several measures that can be taken to prevent flooding, including building dams and levees, constructing floodwalls and barriers, and implementing early warning systems.

- How do dams and levees help prevent flooding?
Dams and levees are built across rivers to control the flow of water. They can store excess water during periods of heavy rainfall and release it slowly when the water level goes down. This helps prevent flooding downstream.

- Why is it important to implement early warning systems?
Early warning systems are crucial in alerting people to evacuate their homes and move to safer areas before a flood strikes. These systems can save lives and reduce property damage.

**Section 3: Consequences of Flooding**

- What are the consequences of flooding?
Flooding can cause significant damage to properties, infrastructure, and the environment. It can lead to loss of life, displacement of people, and economic losses.

- How does flooding affect the environment?
Flooding can have severe environmental consequences, including soil erosion, contamination of water sources, and destruction of wildlife habitats.

- What can be done to minimize the impact of flooding on the environment?
To minimize the environmental impact of flooding, it is essential to develop and enforce policies that promote sustainable land use, maintain natural habitats, and reduce pollution.

**Conclusion:**
In conclusion, understanding the causes of flooding, preventing it, and dealing with its consequences are essential for protecting lives and properties. By learning about the Missouri River flooding, we can gain insights into how to prevent and mitigate the impact of similar events in the future.

Lesson: Introduction to Skiing

## Section 1: Theoretical Concepts
Skiing is a winter sport that involves using skis to glide on snow. It is a popular activity that people of all ages can enjoy. In this lesson, we will learn about the basics of skiing, including the equipment used and the techniques involved.

## Section 2: Practical Examples
To begin, let's talk about the equipment used in skiing. There are two main types of skis: alpine skis and Nordic skis. Alpine skis are used in downhill skiing, while Nordic skis are used in cross-country skiing. Both types of skis have a base made of a smooth material like plastic or metal, and edges that help the skier turn and control speed. Skis also have bindings that attach to boots worn by the skier.

Now let's talk about the techniques involved in skiing. There are three main types of skiing: alpine, Nordic, and telemark. Alpine skiing is the most popular type of skiing and involves using alpine skis to descend a slope. Nordic skiing involves using Nordic skis and poles to move across a snow-covered terrain. Telemark skiing is a style of skiing that involves using alpine skis but with a different stance and technique.

## Section 3: Real-World Scenarios
To practice skiing, you need to find a snowy mountain or hill. Once you arrive at the ski resort, you will need to take a ski lift or gondola up the mountain. Then, you can start skiing down the slope! Remember to keep your balance and use your poles when skiing uphill. Always ski within your ability level and be aware of other skiers on the mountain.

## Glossary
- Alpine skis: Skis used for downhill skiing
- Nordic skis: Skis used for cross-country skiing
- Bindings: Device that attaches skis to boots
- Poles: Used for balance and propulsion in Nordic skiing
- Telemark skiing: Style of skiing that uses a different stance and technique than alpine skiing

## Conclusion
Skiing is a fun and exciting winter activity that anyone can learn. By understanding the basics of skiing and practicing the techniques involved, you can enjoy the snowy mountains and improve your skills over time. Whether you are a beginner or an experienced skier, there is always something new to learn and discover in the world of skiing.

Lesson: The Environment in Art

Introduction:
The environment has been an important subject for artists since the beginning of time. It has been used to express emotions, tell stories, and convey messages. In this lesson, we will explore how the environment has been experienced and imagined in art from the eighteenth century to the present day.

Section 1: The Environment in Art History

Topic 1: Ruins
Ruins have been a popular subject in art history. They represent the passage of time, decay, and the fragility of human achievements. Artists like John Constable and J.M.W. Turner painted landscapes that included ruins to create a sense of melancholy and nostalgia.

Topic 2: Re-enactments
Some artists use re-enactments to explore historical events or cultural practices. For example, the artist Patrick Keiller created a film called "Robinson in Ruins" where he re-enacted the journey of Robinson Crusoe. This re-enactment allowed him to explore the relationship between reality and fiction.

Topic 3: Cultural Memories
Artists also use the environment to explore cultural memories. For example, the artist Yinka Shonibare created a sculpture of a windmill that was once used to produce sugar in the Caribbean. He covered the sculpture with brightly colored fabrics to represent the African culture that was forced into slavery to work in the sugar plantations.

Section 2: The Environment in Contemporary Art

Topic 1: Land Art
Land Art is a type of art that uses natural environments as its canvas. Artists like Robert Smithson and Michael Heizer created large-scale installations in the desert that changed over time due to natural forces like wind and water.

Topic 2: Eco Art
Eco Art is a type of art that raises awareness about environmental issues. Artists like Betsy Damon and Helen Mayer Harrison use plants, soil, and other natural materials to create installations that explore themes like sustainability and climate change.

Topic 3: Site-Specific Art
Site-specific art is art that is created specifically for a particular location. Artists like Richard Long and Andy Goldsworthy create art that is influenced by the environment in which it is located. For example, Goldsworthy creates sculptures out of rocks, leaves, and other natural materials found on the site.

Section 3: The Environment in Your Life

Discussion:
- How can you incorporate the environment into your daily life?
- What can you do to help protect the environment?
- How can you use art to raise awareness about environmental issues?

Conclusion:
The environment has been an important subject for artists for centuries. By exploring the environment in art history and contemporary art, we can gain a deeper understanding of how artists use the environment to express emotions, tell stories, and convey messages. We can also learn how to incorporate the environment into our daily lives and use art to raise awareness about environmental issues.

Induction of sister chromatid exchanges by carcinogens mediated through cultured rat liver epithelial cells.
A cloned, untransformed rat liver cell-line, LNRL (with the normal diploid karyotype and epithelial morphology) was tested for use as the metabolizing component in a co-cultivation system for carcinogen-screening using sister chromatid exchanges (SCE) as the criterion. The well characterized early cultures of LNRL cells were co-cultivated with Chinese hamster ovary (CHO) cells, the target commonly used for the induction of SCE, and exposed to different concentrations of various chemicals for 24 h. Two polycyclic hydrocarbons, 7,12-dimethylbenz[a]anthracene and benzo[a]pyrene did not produce any SCE in CHO cells cultured alone, but produced a significant number of SCE in CHO co-cultivated with LNRL. The aromatic amine, 2-acetylaminofluorene, and the potent carcinogenic mycotoxin, aflatoxin B1, induced SCE to a limited extent even in CHO cells cultivated alone, but in the presence of liver cells the SCE frequency was greatly increased. Aflatoxin G2, the least potent of the aflatoxins, also produced a response in the co-cultivation system. These results indicate that cultured liver cells can be used as the metabolizing cells in co-cultivation systems for carcinogen-screening. The advantages of this assay over those employing liver microsomal fractions are discussed.

Lesson: Introduction to Sister Chromatid Exchanges and their Induction by Carcinogens

**Objective:** To introduce the concept of sister chromatid exchanges (SCE) and their induction by carcinogens using cultured rat liver epithelial cells.

**Prerequisites:** Basic knowledge of cell biology and genetics.

**Materials:** None

**Introduction:** Sister chromatid exchanges (SCE) are a type of genetic mutation that occurs when two identical chromatids separate during cell division. This can lead to genetic instability and an increased risk of cancer. In this lesson, we will explore how carcinogens can induce SCE in cultured rat liver epithelial cells and how this can be used as a screening tool for cancer-causing substances.

**Section 1: What are Sister Chromatid Exchanges?**

Sister chromatid exchanges (SCE) are a type of genetic mutation that occurs when two identical chromatids separate during cell division. This can lead to genetic instability and an increased risk of cancer. SCE can be caused by various factors, including radiation, chemicals, and certain viruses.

**Section 2: Induction of Sister Chromatid Exchanges by Carcinogens**

Carcinogens are substances that can cause cancer. Some carcinogens can induce SCE in cells, which is a sign of genetic instability and an increased risk of cancer. In this study, we will look at how cultured rat liver epithelial cells respond to different carcinogens and whether they induce SCE.

**Section 3: Experimental Setup**

To test the induction of SCE by carcinogens, we will use a co-culture system where cultured rat liver epithelial cells (LNRL) are grown together with Chinese hamster ovary (CHO) cells. The CHO cells are commonly used for the induction of SCE. We will expose the cells to different concentrations of various chemicals for 24 hours and then analyze the number of SCE induced in the CHO cells.

**Section 4: Results**

We found that two polycyclic hydrocarbons, 7,12-dimethylbenz[a]anthracene and benzo[a]pyrene, did not produce any SCE in CHO cells cultivated alone, but produced a significant number of SCE in CHO co-cultivated with LNRL. The aromatic amine, 2-acetylaminofluorene, and the potent carcinogenic mycotoxin, aflatoxin B1, induced SCE to a limited extent even in CHO cells cultivated alone, but in the presence of LNRL, they induced a significantly higher number of SCE.

**Section 5: Conclusion**

In conclusion, our study shows that cultured rat liver epithelial cells can induce SCE when exposed to certain carcinogens. This finding has important implications for cancer research and drug development, as it provides a useful tool for screening potential cancer-causing substances. By understanding the mechanisms behind SCE induction, we can better predict and prevent the development of cancer.

Q:

Web App runs inside Webview and installed like a native App

I created a Web App(PWA) via React and Bootstrap. It runs perfectly. I planned to create an Android and another iOS Apps that have only one page with a Webview that loads my Web App via URL and ship those Apps to the customer.
My question is that there is a better and standard way to this? I heard about Hybrid Frameworks like IONIC but as I understand, IONIC Apps, Are web Apps that run on device not loaded from a URL, Is that right?
What I want is that my changes in the server affect all users and Apps installed on their devices. Because of that, I created the PWA App, not the Native App. I searched a lot but I can't reach a final decision.
Used to be I was an Android developer and had a lot of problems with shipping the latest version to the customer, Now I want to use Web-based technologies to reach Apps that works like a website.

A:

The issue here is: you will not be able to use the devices resources if you load the PWA in a Webview. For example push notifications will not work. A PWA can be installed onto a phone and windows as an application. This will have push notification on Android and Windows but not on Mac or iOS (Safari is the new IE). You need to go Hybrid or back to Native if you need more.
You are right with IONIC. It is a wrapper for a webapp stored on the device but it allows us to use native features (push works on both Android and iOS). But you still have the distribution issue since you need to publish to the stores every version. Not even mentioning the hoops apple gets you through when you try to publish.
The good thing with IONIC is you have a single source code for multiple platforms and you can choose the library you want to build with. It used to be Angular but now you can choose ReactJS, Vue, Angular or ES. Which makes it way friendlier.
With IONIC you could build the native features and lazy load the rest as dynamic component from a url: stackoverflow question if you do not care about backward compatibility.
I did both PWA and IONIC. Both has their pros and cons.
If I do not care about iOS and Apple I would stay with PWA otherwise IONIC.

Lesson:
Title: Harvesting Methane using Deep-Sea Worms and Bacteria
Level: Primary through High School

Introduction:
Methane is a colorless, odorless, and highly flammable gas that is the main component of natural gas. It is also a potent greenhouse gas that contributes to global warming. However, deep-sea worms and bacteria have found a way to harvest methane from the ocean floor without causing harm to the environment. This lesson will explore how these creatures work together to produce energy and how we can use their methods to create sustainable energy solutions.

Section 1: Understanding Methane Production
Topic 1: What is Methane?
- Methane is a type of gas that is produced by certain types of bacteria and archaea in the absence of oxygen.
- It is also known as marsh gas or swamp gas and is created by the decomposition of organic matter in waterlogged areas.
- Methane is a major component of natural gas and is used as a fuel for heating, cooking, and electricity generation.

Topic 2: How do Deep-Sea Worms and Bacteria Produce Methane?
- Deep-sea worms and bacteria live in the sediment on the ocean floor and produce methane through a process called methanogenesis.
- Bacteria in the sediment break down organic matter and release methane gas as a byproduct.
- Deep-sea worms then feed on these bacteria and produce methane as a waste product.
- This process is called symbiosis, where two different organisms live together and benefit each other.

Section 2: Applying Methane Production to Sustainable Energy Solutions
Topic 3: How can we use Methane Production to Create Sustainable Energy Solutions?
- One way to harness the power of methane production is through biogas generation.
- Biogas is produced when organic matter breaks down in the absence of oxygen and releases methane gas.
- This gas can be captured and used as a renewable source of energy.
- Biogas plants can be set up to convert agricultural waste, food waste, and even human waste into clean energy.

Topic 4: Advantages of using Methane as a Renewable Source of Energy
- Methane is a clean-burning fuel that produces fewer emissions than coal or oil.
- Biogas plants can be set up at the source of waste, reducing transportation costs and emissions.
- Methane can be used to generate electricity, heat homes, and power vehicles.
- Methane production is a closed loop system, meaning that the waste product of one organism becomes the food source of another, creating a sustainable cycle.

Section 3: Practical Examples and Applications
Topic 5: Real-World Examples of Methane Production
- There are several companies that are working to harness the power of methane production.
- Calysta of Menlo Park and Unibio of Denmark are two companies that are developing ways to grow and harvest bacteria that produce methane for feeding fish and livestock.
- These companies are using the natural processes of deep-sea worms and bacteria to create sustainable energy solutions.

Topic 6: Conclusion
- Harvesting methane from deep-sea worms and bacteria is a sustainable and environmentally friendly way to produce energy.
- By understanding the processes involved in methane production, we can create innovative solutions to reduce our reliance on fossil fuels and combat climate change.
- As we continue to explore the possibilities of methane production, we can look forward to a brighter future powered by clean, renewable energy.

Glossary:
- Methanogenesis: the process by which certain bacteria and archaea produce methane gas as a byproduct of their metabolism.
- Symbiosis: a close and long-term interaction between two different organisms that usually benefits both parties.
- Biogas: a mixture of gases produced by the breakdown of organic matter, including methane, in the absence of oxygen.
- Methane: a colorless, odorless gas that is the main component of natural gas and is a potent greenhouse gas.

Conclusion:
In conclusion, harvesting methane from deep-sea worms and bacteria is a sustainable and environmentally friendly way to produce energy. By understanding the processes involved in methane production, we can create innovative solutions to reduce our reliance on fossil fuels and combat climate change. As we continue to explore the possibilities of methane production, we can look forward to a brighter future powered by clean, renewable energy.

Lesson: Understanding the Role of Promotion in Marketing

Introduction:
Marketing is an essential aspect of business that involves promoting, selling, and distributing goods or services. One of the key components of marketing is promotion, which refers to activities that communicate the features and benefits of a product or service to potential customers. In this lesson, we will explore the role of promotion in marketing and learn how it can help businesses succeed.

Section 1: The Importance of Promotion in Marketing

Topic 1: Building Brand Awareness
Promotion plays a crucial role in building brand awareness among potential customers. By creating a strong brand image and message through advertising, public relations, and other forms of promotion, businesses can differentiate themselves from competitors and establish a presence in the market.

Topic 2: Generating Sales and Revenue
Promotion is also essential in generating sales and revenue for a business. By reaching out to potential customers through targeted advertising campaigns, businesses can attract new customers and encourage existing ones to make repeat purchases. This can lead to increased sales and ultimately, higher profits.

Topic 3: Creating Customer Loyalty
Promotion can also help businesses create customer loyalty by providing incentives for customers to continue doing business with them. For example, companies may offer discounts, coupons, or loyalty programs to encourage customers to return and make repeat purchases.

Section 2: Types of Promotion
There are several types of promotion that businesses can use to reach potential customers, including:

1. Advertising: This involves paying to have a message communicated through various media channels such as television, radio, newspapers, magazines, billboards, or online platforms.

2. Public Relations: This involves creating a positive image for a company through various means such as press releases, events, or sponsorships.

3. Personal Selling: This involves one-on-one communication between a salesperson and a potential customer to persuade them to purchase a product or service.

4. Direct Marketing: This involves sending promotional messages directly to potential customers through mail, email, or phone calls.

Section 3: Examples of Promotion in Action

Topic 1: Coca-Cola's "Share a Coke" Campaign
Coca-Cola launched a successful promotion campaign in 2011 called "Share a Coke." The campaign involved printing popular names on Coke bottles and cans, encouraging consumers to buy and share the drinks with friends and family whose names appeared on the packaging. The campaign was a huge success, leading to increased sales and brand awareness for the company.

Topic 2: Nike's "Just Do It" Campaign

Who would have imaged, even for a moment, some years back, that youths from the remote village of Shakriyah south of Jordan, will walk the Red Carpet to compete with big time Hollywood stars for the global Oscars award? Whoever thought, out of fantasy, that a Jordanian film would get selected, as Theeb did, to candidate for the Oscars, and rival cinema industry top-gun international movies like The Revenant, Mad Max: Fury Road, Big Short, Bridge of Spies, Brooklyn, The Martian, among others? Who?

However, it is imperative that we overcome our surprise and joy with this film, its stars, and the makers of this achievement, primarily with scenarist Basel Ghandour and Director Naji Abu Nuwar, and consider the phases “post” and “pre” Theeb! This film that took the Jordanian story and presented it to the world, is beyond what some call a “success story”, it is a story of creativity on one side, and a story that tells the failures of official institutions —of all scales and varieties, including civil societies, in regards to the creation of an environment with the capacity to incubate creativity, excellence, and achievement.

This failure is not in arts, culture, education, investment, and industry, alone but is also in terms of appreciating such brilliance and nurturing it.

Accordingly, you may see this dismissal of creativity, skill, and achievement in aspects of the government’s reactions, so far, towards the inventors of Theeb, who deserved an official and popular departure ceremony on the occasion of them leaving to Los Angeles, or their arrival back from having made such an achievement within the tight financial limitations that confined their work, and the efforts of the young cast who were eager to venture with heads held high and such creativity as the government and respective organisations and institutions remained fast asleep!

“Theeb”, gentlemen, gives rise to an essential question; the question of creativity, brilliance, and achievement. This film didn’t receive any official attention until the initial footages came out when the King Abdullah Development Fund stepped in for this movie to become an international film with minimal capabilities. This in turn means that there is real fertile grounds for creativity, but consequentially this creativity requires an “incubator”; legally, administratively, culturally, and societally.

Governments and policies over the years, day in day out, have successfully created environments that gave rise to extremism. These policies have also transformed Jordan from a transit stop for drugs into a “social host” for them. But they utterly failed to create a suitable hosting environment for creativity; not only artistically, but culturally, academically, scientifically… etc.

So much Jordanian human capabilities migrate! So many Jordanians achieved enormously for themselves abroad; from media people to academics, scientists, and professionals!

We haven’t a problem with the “seeds of creativity”, they are readily available. The problem is the “environment” that suffocates them! And saying it is a matter of shortage in funds is far from true, “Theeb” was made with a budget one tenth of any one of the movies and films it rivalled, and by local expertise and the brilliance of a youths!

Along these lines, education is steeping and universities are crumbling; Jordanian drama has been destroyed, and the Jordanian Football League gives much less now that it once did years ago. The national basketball team has declined in performance, an in terms of theatre; Mousa Hijazin has to pay out of his own pockets due to lack of real sponsorship for theatricals, as Jordanian stars of drama pass away in grieving financial situations whilst some like Mohammad Al Qabbani have over a hundred pieces of work published.

So, instead of moving forward, we take a wide step back!?! But who said we suffer the managerial inadequacies, policies, and immaturities of Officials? Whoever said the State suffocates brilliance and creativity?

Youth leadership is more crucial than ever in the global response to HIV

HomeNews & EventsYouth leadership is more crucial than ever in the global response to HIV

This International Youth Day, what do you think is the biggest issue affecting young people? Unemployment? Affordable housing? The extortionate rise in the price of Freddo’s? One youth issue that I feel is often forgotten is the global HIV & AIDS epidemic.

Despite enormous progress in the fight against the epidemic, young people are still disproportionately affected by HIV & AIDS. AIDS is now the second biggest killer of young people globally – in 2000 it wasn’t even in the top ten. And young people from marginalised groups too often find their human rights and access to equitable healthcare systematically violated.

Despite the growing impact of HIV on young people globally and the fact that still only half of all people in need of life-saving ARVs have access to them, there are worrying signs of HIV being deprioritised by donors globally, including by the UK Government.

In response to the UK’s deprioritisation of HIV, Youth Stop AIDS, supported by STOPAIDS and Restless Development, launched the It Ain’t Over Campaign. We’ve been calling on the UK Government to financially, politically and programmatically re-prioritise HIV and be global leaders in beating AIDS by 2030.

Through creative action, community engagement and lobbying key decision makers – young people across the country have told the public and parliamentarians alike that HIV & AIDS ‘Ain’t Over’. To date, nearly 200 MPs have been lobbied by Youth Stop AIDS campaigners and around 50 MPs have taken action in parliament, writing to the Secretary of State for International Development Priti Patel, tabling parliamentary questions and raising the issue in debates.

Since the launch of the campaign, thanks to the hard work of hundreds of passionate Youth Stop AIDS campaigners and our youth-led Steering Committee, ‘It Ain’t Over’ has made some big wins. This includes endorsement from a wide group of INGOs, securing an official Parliamentary Inquiry into DFID’s deprioritisation of HIV, and seeing HIV become more visible in key DFID strategies and DFID Ministers’ communications.

To celebrate International Youth Day, I met two pioneering Youth Stop AIDS activists and Shadow Secretary for International Development Kate Osamor MP, to find out how they supported the It Ain’t Over campaign and why they think young people are so important to the global HIV response.

Abi, President of Youth Stop AIDS at Sussex University

Abi, 21, from London is the current President of the Sussex University branch of Youth Stop AIDS. The Sussex Youth Stop AIDS group has organised a whole range of creative stunts. Abi remarked, “we even organised there to be a huge bouncy castle… and used the phrase ‘Don’t Let HIV Bounce Back’ to raise awareness of the campaign and encourage HIV testing”.

Abi thinks young people are really important in the HIV response and need to use their voice to influence decision makers. The Sussex group has met a number of parliamentarians including the former Minister for International Development, James Wharton. Abi reflected to me that ‘it was amazing how willing MPs were to get involved – in particular Caroline Lucas was an absolute star and offered to support in any way she can’.

Krishen, Writer and HIV Activist

Krishen, a young man living with HIV from South Africa, got involved with Youth Stop AIDS last year when he joined his local group at Queen Mary’s University.

Krishen then went on to be a speaker on the annual Youth Stop AIDS Speaker Tour. The Speaker Tour gave a platform to young people living with HIV to tell their own stories and inspire the public and decision makers to take action on the campaign. The Speaker tour included over 15 public events and secured media coverage in publications like The Metro and BBC World Service.

Krishen said that ‘going on the Speaker Tour was a really wonderful experience. It was really powerful to go all over the UK speaking to young people and decision makers, including at DFID and in Parliament, and to see how much difference it made for them to hear first hand accounts from young people living with HIV’.

Krishen’s empowered activism reflects his strong beliefs on the crucial role that young people should play in the global HIV response. Krishen told me that he believes ‘young people have a strong, powerful voice and it’s really important that young people recognise the role that they can play in combating the epidemic’.

Kate Osamor, Shadow Secretary of State for International Development

As Shadow Secretary of State for International Development, Kate has played a critical role holding the Government to account and supporting the It Ain’t Over Campaign. She kindly agreed to answer a few questions about how she’s become involved with the campaign.

Why do you support the It Ain’t Over Campaign?
When I met with Youth Stop AIDS campaigners I was alarmed to hear about funding cuts to the UK government’s global work on HIV and the expiration of DFID’s strategy on HIV. I’m proud that the UK has historically been a leader in the global HIV response but am worried that we’ve now taken our eye off the ball and that we risk undoing all the progress made so far. I support Youth Stop AIDS in calling on the UK Government to increase financial, programmatic, political commitment to the global HIV response.

Why are young people so important in the global HIV & AIDS response?There are 1.8 billion young people in the world – the largest generation of youth ever in the world – and it’s high time governments stop seeing them as a problem and start working with them as a solution. Just a fortnight ago, I was with youth activists in Abuja on the day they successfully campaigned to remove age restrictions on running for political leadership positions. That same youth leadership is more crucial than ever in the global response to HIV. Young people aren’t just disproportionately affected by HIV – they are the only age group for whom AIDS-related deaths are increasing. Young people therefore have to be one of the solutions to ending the epidemic: with their energy, enthusiasm and knowledge, they’re uniquely placed to effectively reach their peers.

How have you supported the campaign in your role as Shadow Development Minister?
I am proud to support the It Ain’t Over campaign and to have used my position as Shadow Secretary of State for International Development to advocate for renewed UK leadership in the global HIV response. I had the pleasure of giving a keynote speech at STOPAIDS World AIDS Day Conference in December last year and met with Youth Stop AIDS campaigners. In March I travelled to Geneva with STOPAIDS to see first-hand the impact UK investment in global health institutions is making.

Colleagues in the parliamentary Labour Party have also backed the It Ain’t Over campaign, with many Labour MPs taking action and meeting with their Youth Stop AIDS campaigners based in their constituency. I was really pleased that the Labour manifesto included a strong commitment to investing to end the HIV, TB and malaria epidemics, in line with the Sustainable Development Goal target.

It’s clear that thanks to Youth Stop AIDS campaigners and parliamentary support, It Ain’t Over has had some big wins. But with HIV still falling off the global agenda, our work must continue. Sign up here to find out more and take action with Youth Stop AIDS – http://youthstopaids.org/itaintover/

Lesson: Understanding the Global HIV & AIDS Epidemic

Introduction:
The global HIV & AIDS epidemic is a major public health issue that has affected millions of people worldwide. Despite significant progress in recent years, young people are still disproportionately affected by the virus. In this lesson, we will explore the causes and consequences of HIV & AIDS, as well as the importance of youth leadership in addressing the epidemic.

Section 1: Understanding HIV & AIDS

**Topic 1: What is HIV?**
HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, which is our body's natural defense against illness and disease. When HIV infects a person, it destroys a type of white blood cell called a CD4 cell. As these cells are destroyed, the person becomes more vulnerable to other infections and diseases, which can eventually lead to Acquired Immunodeficiency Syndrome (AIDS).

**Topic 2: How is HIV transmitted?**
HIV is most commonly spread through unprotected sexual contact with an infected person. It can also be transmitted through sharing needles or syringes, or from mother to child during childbirth or breastfeeding.

**Topic 3: Who is at risk for HIV?**
Anyone can get HIV, but certain groups of people are at higher risk than others. These include men who have sex with men, people who inject drugs, and individuals who engage in unprotected sexual activity. Young people, particularly those from marginalized communities, are also at increased risk.

Section 2: Consequences of HIV & AIDS

**Topic 1: Symptoms of HIV**
Many people with HIV do not experience any symptoms after they are infected. However, some people may experience flu-like symptoms within a few weeks after infection. These symptoms can include fever, fatigue, swollen lymph nodes, and rash.

**Topic 2: AIDS**
AIDS is the final stage of HIV infection. It occurs when the virus has weakened a person's immune system so much that they develop opportunistic infections or certain cancers. Without treatment, people with AIDS typically survive for about three years.

Section 3: Youth Leadership in Addressing HIV & AIDS

**Topic 1: Importance of youth leadership**
Young people have a critical role to play in the global response to HIV & AIDS. They are often the most affected by the epidemic, and their voices and perspectives must be included in decision-making processes. Youth leadership can help to ensure that programs and policies are designed to meet the specific needs of young people, and to promote their rights and well-being.

**Topic 2: Examples of youth leadership**
There are many examples of youth leadership in the response to HIV & AIDS. Some organizations, such as the Global Fund Adolescent and Youth Leadership Initiative, provide training and support to young people to become advocates for HIV prevention and treatment. Other initiatives, such as the Youth Champions Initiative, empower young people to take action on HIV & AIDS in their communities.

Conclusion:
In conclusion, understanding the global HIV & AIDS epidemic and the importance of youth leadership in addressing the issue is crucial. By educating ourselves and others about the virus, we can work towards reducing its spread and supporting those affected by it. We also have a responsibility to ensure that young people are included in the decision-making process and that their rights and needs are prioritized in the global response to HIV & AIDS.

Lesson: How to Conduct Effective User Research

## Section 1: Introduction to User Research

User research is the process of studying how people interact with technology to understand their needs and behaviors. This information is used to design products that meet those needs and are easy to use. In this lesson, we will learn about the basics of user research, including its importance, methods, and best practices.

## Section 2: Importance of User Research

User research is essential because it helps us understand what users need and how they interact with technology. By understanding these things, we can design better products that meet users' needs and are easy to use. User research also helps us identify potential problems with our designs and fix them before releasing the product.

## Section 3: Methods of User Research

There are several methods of conducting user research, including:

1. Surveys: Surveys are questionnaires that ask users about their experiences and opinions. They can be conducted online or in person.

2. Interviews: Interviews are one-on-one conversations with users where we ask them about their experiences and opinions. They can be conducted online or in person.

3. Observations: Observations involve watching users interact with technology in a natural setting. This can help us understand how users really use products and services.

4. Diary Studies: Diary studies involve asking users to record their experiences and thoughts over time. This can help us understand how users interact with technology in their daily lives.

5. Focus Groups: Focus groups involve gathering a group of users to discuss their experiences and opinions about a product or service.

## Section 4: Best Practices for Conducting User Research

Here are some best practices for conducting user research:

1. Recruit participants who match your target audience.

2. Create a comfortable environment for participants to share their thoughts and experiences.

3. Use open-ended questions that allow participants to share their thoughts and opinions freely.

4. Record and transcribe interviews and observations to ensure accuracy.

5. Analyze data to identify patterns and themes.

6. Share findings with stakeholders and use them to inform design decisions.

## Section 5: Conclusion

User research is an essential part of the design process. It helps us understand what users need and how they interact with technology. By following the methods and best practices outlined in this lesson, we can conduct effective user research that will inform our designs and lead to better products for our users.


text: A review of research evidence concludes there is nothing to support claims that sugar-free versions of popular soft drinks can help combat obesity and related diseases such as Type 2 diabetes.. Industry-sponsored studies reporting “favourable” associations between diet drinks and weight loss may be biased, it claims... Senior investigator Professor Christopher Millett, from Imperial College London’s School of Public Health, said: “A common perception, which may be influenced by industry marketing, is that because ‘diet’ drinks have no sugar, they must be healthier and aid weight loss when used as a substitute for full sugar versions. However, we found no solid evidence to support this.”.”

Lesson: How to Read and Understand Research Evidence

**Introduction**:
In this lesson, we will learn how to read and understand research evidence. We will focus on a study that examines the relationship between sugar-free soft drinks and obesity. This is an important topic because many people believe that these drinks are healthier than their sugary counterparts, but the research suggests otherwise.

**Section 1: Understanding Research Evidence**:
Research evidence is information that is collected through systematic investigation. It is used to answer questions and test hypotheses about the world around us. In order to understand research evidence, we need to know how to read and interpret it.

**Section 2: Reading and Interpreting Research Evidence**:
When reading research evidence, we need to look at the methods used to collect the data, the results, and the conclusions. We also need to consider the credibility of the source and the reliability of the evidence.

**Section 3: Applying Research Evidence to Real-World Scenarios**:
Once we understand how to read and interpret research evidence, we can apply it to real-world scenarios. For example, if we know that sugar-free soft drinks do not help with weight loss, we can make informed decisions about our own diet and health.

**Glossary**:
- Research evidence: Information collected through systematic investigation.
- Hypothesis: A tentative explanation for an observed phenomenon.
- Credibility: The trustworthiness of a source.
- Reliability: The consistency of a method or result.
- Methods: The procedures used to collect data.
- Results: The findings of an investigation.
- Conclusions: The interpretation of the results.

**Conclusion**:
By understanding research evidence, we can make informed decisions about our own health and wellbeing. By applying the principles of research evidence to real-world scenarios, we can make better choices about what we eat and drink.

Merton of the Movies (novel)

Merton of the Movies is a comic novel by Harry Leon Wilson. It was adapted into a stage play and three films. Wilson, a writer and novelist, wrote the book after a brief stint in Hollywood. Merton of the Movies was published in the Saturday Evening Post in 1919 and published as a book in 1922. Thomas Hischak described Merton of the Movies as a "light-hearted romp" with characters "cartoonish but endearing". The novel sold millions of copies and has been adapted to other media several times.

Premise and plot
Small-town bumpkin Merton Gill fantasizes about joining the glamorous world of silent films, and takes a correspondence school course in acting. He travels to Hollywood, where he is disillusioned by the foibles of his screen idols. He is befriended by comedienne and stuntwoman Flips Montague, who helps him land a bit part, which he bungles so badly with his comically inept acting that the studio is inspired to use him for comedy. Gill becomes a comedy star, delivering lines that he thinks are serious straight drama.

Lesson: Introduction to Silent Films

## Chapter 1: Overview of Silent Films

Silent films were a type of film that used no synchronized recorded dialogue or singing and often had a pianist or organist playing along with the films in theaters. These films were popular from the late 1800s until the late 1920s when sound films became more common.

## Chapter 2: The Rise of Silent Films

The first silent film was created in 1894 by Thomas Edison and his assistant William Dickson. The film was called "Newark Athlete" and showed a man jumping over a fence. The popularity of these early films led to the creation of many more studios and the development of new techniques for making movies.

## Chapter 3: The Golden Age of Silent Films

The 1910s and 1920s were known as the Golden Age of Silent Films. During this time, many great directors and actors emerged, including Charlie Chaplin, Buster Keaton, and Mary Pickford. Many classic films were made during this time, such as "The Birth of a Nation," "Intolerance," and "The Great Train Robbery."

## Chapter 4: The Decline of Silent Films

Although silent films were very popular, they began to decline in popularity in the late 1920s. This was partly due to the rise of sound films, which allowed for more realistic and immersive experiences for audiences. Additionally, the cost of producing silent films was high, as they required live orchestras to accompany them.

## Chapter 5: Legacy of Silent Films

Despite the decline of silent films, they have left a lasting impact on cinema. Many techniques and styles that were developed during the silent film era are still used today, such as editing, camera angles, and special effects. Additionally, many classic silent films are still enjoyed and studied today.

Glossary:
- Silent Film: A type of film that uses no synchronized recorded dialogue or singing and often has a pianist or organist playing along with the films in theaters.
- Synchronized: To occur at the same time or rate as something else.
- Technique: A way of doing something or a method of achieving a particular end.
- Style: A particular manner or way of doing something.

Conclusion:
Silent films were an important part of the history of cinema and continue to influence filmmaking today. By studying these films, we can learn about the early days of cinema and gain a deeper appreciation for the art form.
