Many birds that form flocks compete through aggressive interaction for priority of access to resources such as food and shelter. The result of repeated interactions between flock members is that each bird gains a particular social status related to its fighting ability, with priority of access to resources increasing with higher status. As the number and intensity of interactions between birds increase, however, so increase the costs to each birds in terms of energy expenditure, time, and risk of injury. Thus, birds possessing attributes that reduce the number of costly interactions in which they must be involved, without leading to a reduction in status, are at an advantage. An external signal, such as a plumage type, announcing fighting ability and thereby obviating the actual need to fight, could be one such attribute.
Paragraph 2
The zoologist Rohwer assented that plumage variations in “Harris sparrows” support the status signaling hypothesis (SSH). He reported that almost without exception birds with darker throats win conflicts with individuals having lighter plumage. He claimed that even among birds of the same age and sex the amount of dark plumage predicts relative dominance status.
Paragraph 3
However, Rohwer’s data do not support his assertions: in one of his studies darker birds won only 57 out of 75 conflicts; within another, focusing on conflicts between birds of the same age group or sex, darker birds won 63 and lost 62. There are indications that plumage probably does signal broad age-related differences in status among Harris sparrows: adults, usually dark throated, have higher status than juveniles, who are usually light throated; moreover, juveniles dyed to resemble adults are dominant over undyed juveniles. However, the Harris sparrows’ age-related plumage differences do not signal the status of individual birds within an age class, and thus cannot properly be included under the term “status signaling.”

Remember billboards? I do.As a young kid in California, my experiences from the back seat of our car mostly alternated between: “Mom, when are we there?” and “Uh, look, McDonald’s, can we go?” whenever one of those 10-foot billboards popped up on the side of the road.Growing up with Indian parents, the answer to both of those would, most times, be the same: “not yet.”Sometimes, big brands would even start a billboard war, like this one between Audi and BMW, which got quite a few laughs:
In 2015, a ton of my clients still spent hundreds of millions of dollars on billboard advertising.Unfortunately or fortunately, billboard advertising is mostly dead.Just think of it this way: Google and Facebook generate more revenue than any traditional media company because they control more eyeballs. That’s why digital marketing matters; it’s where the attention is.The reason why billboards, like the ones above, will die, is because the future of driving will look like this:
Although driverless cars already exist, drivers still have to pay attention; in the future, as the technology improves, not a single passenger will spend their time looking at the road.Do me a favor, the next time you drive and are giving a friend a ride, take a peek at the passenger seat. Even now, chances are they’ll be looking at their phone. If no one is looking at the road anymore, who’s supposed to see those advertisements?That means you don’t have much time to figure out this digital marketing stuff before you can power down your old school printing press and close up shop.

Unemployment has become one of the biggest problems around the world. When an individual is an implied, he or she will know very less about the mankind. It is so difficult to face situation and handle situations when the individual is unemployed. Unemployment leads to many silly mistakes. And an unemployed person cannot take over the family and lead the family as well. There is a huge competition in highly populated countries like India. In order to be employed, the only method is to study hard and improve the skills and score better. Basically, the students are not showing good amount of interest towards the studies. Let us now see how to motivate them.
Covid crisis has made many people unemployed. It has taken away the basic need of living. Many people are left with the unfilled stomachs. Some people are dead about by not finding a way to live.
Types of unemployment :
There are four main types of unemployment in an economy frictional, structural, cyclical, and seasonal and each has a different cause.
1. Frictional unemployment :
Frictional unemployment is caused by temporary transitions in workers lives, such as when a worker moves to a new city and has to find a new job. Frictional unemployment also includes people just entering the labor force, such as freshly graduated college students. It is the most common cause of unemployment, and it is always in effect in an economy.
2. Structural unemployment :
Structural unemployment is caused by a mismatch in the demographics of workers and the types of jobs available, either when there are jobs available that workers don’t have the skills for, or when there are workers availabes but no jobs to fill. Structural unemployment is most obvious in industries undergoing technological advancements.
3. Cyclical unemployment :
Cyclical unemployment is caused by declining demand. When there is not enough demand in an economy for goods and services, businesses cannot offer jobs . According to keynesian economics , cyclical unemployment is a natural result of the business cycle in times of recession: if all consumers become fearful at once, consumers will attempt to increase their saving at the same time, which means there will be a decrease in spending, and businesses will not be able to employ all employable workers.
4. Seasonal unemployment :
Seasonal unemployment is caused by different industries or parts of the labor market being available during different seasons. Fot instance, unemployment goes up in the winter months, because many agricultural jobs end oncr crops are have harvested in the fall, and those wotkers are left to find new jobs.
Consequences of unemployment in an Economy :
Low unemployment is key to economic stability High and long- term unemployment can cause significant stress on a nation in three key areas.
* Individuals :
Unemployed people have no ability to fulfill their financial obligations and can become mentally stressed, ill, and even homeless.
* Economic efficiency :
During times of high unemployment many job seekers will accept new jobs below their skill level, a situation called “underemployment ” which translates to a loss of human capital for an economys labor market. Unemployed workers will also significantly decreases their consumer spending, which is one of the driving forces of economic growth. Without consumer spending, the economy will slow dramatically.
* socio- political stability :
If unemployment remains high, citizen dissatisfaction can rise to the point of widespread civil unrest.
Possible solutions for Unemployment :
Solving unemployment is a hotly debated topic, and no economists agree on one simple way to do it. However, in the U.S ,if unemployment rises noticeably, the government usually steps in with specific policies designed to lower the total number of unemployed people.
1. Monetary policy :
Monetary policy is financial influence implemented by a central bank . Monetary policies usually come in the form of lower interest rates, which increase the total money supply within an economy by allowing banks and businesses more access to loans and therefore, more accessible spending power.
2. Fiscal policy :
If expansionary monetary policy doesn’t adequately lower the unemployment rate government agencies will turn to fiscal policy. Fiscal policy is fiscal stimulus implemented by the national government and fiscal policies include spending on infrastructure, proposingtax cuts , increasing the minimum wage, or implementing unemployment benefits. These methods are designed to inject more demand into private economy and strengthen economic activity.
Let us now see some of the ways to motivate the students to study and get employeed.
• Make things easier :
Showing the things easier and explaining them with clarity helps the students to show better interest on the subject and makes them to pay more attention on what the teacher is trying to convey. When the topics are shown easier for the students, they start learning them and they feel achieved and they pay more attention to study. When a student learns a particular topic or a question, he/she feels comfortable and happy for getting it. Once if they start reading, they develop the interest in them and they continue to read more and more.
• Tell the importance :
The students must be motivated with good number of words to understand the need of studying and what happens if they don’t study. A student is like a bird without the wings when they don’t study. So, it is very important to motivate students to study and to make them understand the need of the situation. Motivation brings the right change in the students who are not interested in learning. It develops the interest in them to study.
It seems good if the government provides good number of jobs.

What it means to “explain” something in science often comes down to the application of mathematics. Some thinkers hold that mathematics is a kind of language–a systematic contrivance of signs, the criteria for the authority of which are internal coherence, elegance, and depth. The application of such a highly artificial system to the physical world, they claim, results in the creation of a kind of statement about the world. Accordingly, what matters in the sciences is finding a mathematical concept that attempts, as other language does, to accurately describe the functioning of some aspect of the world
At the center of the issue of scientific knowledge can thus be found questions about the relationship between language and what it refers to. A discussion about the role played by language in the pursuit of knowledge has been going on among linguists for several decades. The debate centers around whether language corresponds in some essential way to objects and behaviors, making knowledge a solid and reliable commodity; or, on the other hand, whether the relationship between language and things is purely a matter of agreed-upon conventions, making knowledge tenuous, relative, and inexact.
Lately the latter theory has been gaining wider acceptance. According to linguists who support this theory, the way language is used varies depending upon changes in accepted practices and theories among those who work in particular discipline. These linguists argue that, in the pursuit of knowledge, a statement is true only when there are no promising alternatives that might lead one to question it. Certainly this characterization would seem to be applicable to the sciences. In science, a mathematical statement may be taken to account for every aspect of a phenomenon it is applied to, but, some would argue, there is nothing inherent in mathematical language that guarantees such a correspondence. Under this view, acceptance of a mathematical statement by the scientific community–by virtue of the statement’s predictive power or methodological efficiency–transforms what is basically an analogy or metaphor into an explanation of the physical process in question, to be held as true until another, more compelling analogy takes its place.

In 1666, one of the most influential scientists in history was strolling through a garden when he was struck with flash of creative brilliance that would a change the world. While standing under the shade of apple tree, Sir Issac Newton saw an apple tree fall to the ground . “Why should that apple always descend perpendicularly to the ground”, Newton wondered . “Why should it not go sideways , or upwards , but constantly to earths center? Assuredly the reason is, that the earth draws it. there must be a drawing power in matter “. And thus the concept of gravity was born . The story of falling apple has become one of the lasting and iconic examples of creative moment. It is a symbol of the inspired genius that fills your during those ” eureka moments” when creative conditions are just right. What most people forget, however , is that newton worked on his ideas about gravity for nearly twenty years until, in 1687 , he published his groundbreaking book , “THE PRINCIPIA: MATHEMATICAL PRICIPLES OF NATURAL PHILOSOPHY.” The falling apple was merely the beginning of a train of thought that continued for decades .
Creative thinking requires our brains to make connections between seemingly unrelated ideas.

The governance of nations differs significantly based on who has power. There are different forms of government. ✓Aristocracy ✓Monarchy ✓Autocracy ✓Oligarchy ✓Theocracy ✓Democracy ✓Republic
Aristocracy
A form of government in which power is in the hands of a small previleged ruling class (nobels). Example: United Kingdom, Spain
Monarchy
A system of government in which one person reigns supreme, usually a king or queen (constitutional monarchy). Example: Bhutan, Oman, Qatar
Autocracy
A system of government by one person with absolute power. Example: North Korea, Saudi Arabia
Oligarchy
A small group of people having control of a country or organisation. Example: Former Soviet Union, China, Venezuela, North Korea
Theocracy
A system of government in which religious doctrines form the basis of government headed by a priest who rules in the name of God or proclaims himself as a God. Example: Vatican
Democracy
A system of government in which eligible members in the population vote to elect their elected representatives, and the party or individual who obtains the majority votes forms the government. Example: India, USA, France
Republic
A state in which supreme power is held by the people and their elected representatives and which has an elected or nominated President rather than a monarch. Example: India, Australia

Health education is a profession of educating people about health. Areas within this profession encompass environmental health, physical health, social health, emotional health, intellectual health, and spiritual health, as well as sexual and reproductive health education.
Health education teaches about physical, mental, emotional and social health. It motivates students to improve and maintain their health, prevent disease, and reduce risky behaviours. It also focuses on emotional, mental and social health too. Educating students on the importance of health builds their motivation.
Health education is one strategy for implementing health promotion and disease prevention programs. Health education provides learning experiences on health topics. Health education strategies are tailored for their target population. Health education presents information to target populations on particular health topics, including the health benefits/threats they face, and provides tools to build capacity and support behavior change in an appropriate setting.
History
From the late nineteenth to the mid-twentieth century, the aim of public health was controlling the harm from infectious diseases, which were largely under control by the 1950s. By the mid 1970s it was clear that reducing illness, death, and rising health care costs could best be achieved through a focus on health promotion and disease prevention. At the heart of the new approach was the role of a health educator.
Code of ethics
The Health Education Code of Ethics has been a work in progress since approximately 1976, begun by the Society for Public Health Education (SOPHE).
“The Code of Ethics that has evolved from this long and arduous process is not seen as a completed project. Rather, it is envisioned as a living document that will continue to evolve as the practice of Health Education changes to meet the challenges of the new millennium.”
Importance of Health Education .
Health education builds student’s knowledge, skills, and positive attitudes about health. Health education teaches about physical, mental, emotional and social health. It motivates students to improve and maintain their health, prevent disease, and reduce risky behaviours.
Health education curricula and instruction help students to learn skills so that they will use to make healthy choices throughout their lifetime.
Health education teaches people of all ages about how diet and exercise contribute to a healthy lifestyle. It also encourages positive changes in behaviour and lowers the risk of addiction to drugs, alcohol and unsafe sexual practices. The majority of schools around the country have courses aimed at teaching health education to students. These courses often revolve around the body, healthy eating, sex and exercising. Some students are taught basic health and physical fitness early on. More in-depth courses are designed for middle and high school students.
Health education encourages a person to make healthy choices. They are instructed to avoid unhealthy habits. ‘A sound mind lives in a sound body’. Rabindranath Tagore and C.V. Raman, if they were confined to sick bed, could not have won the Nobel Prize. In fact, a sickly student with all his talents and abilities lags behind in the race of life.
Health education also teaches about the emotional and mental health of the student. A healthy person is the happiest person in the world.
