In addition to inactive and unsupportive environment, genes and family history also contribute to overweight and obesity cases. Studies of identical twins who have been raised apart how that genes have a strong influence on a person's weight. Overweight of obesity tend to run in families. Your chances of being overweight are greater if one or both of your parents one overweight or obese. Your genes also may affect the amount of fat you store in your body and where on your body you carry the extra fat. Because families also share food and physical activity habits, a link exists between genes and the environment. Children adopt the habits of their parents. A child who has overweight parents who eat high-calorie foods and are inactive will likely become overweight too. However, if the family adopts healthy food and physical activity habits, the child's chance of being overweight or obese is reduced.
Some hormone problems may also cause overweight and obesity, such as underactive thyroid (hypothyroidism), Cushing's syndrome and polycystic ovarian syndrome (PCOS). Underactive thyroid is a condition in which the thyroid gland does not make enough thyroid hormone. Lack of thyroid hormone will slow down your metabolism and cause weight gain. Cushing's syndrome is a condition in which the body's adrenal glands make too much of the hormone cortisol. People who have Cushing's syndrome gain weight have upper-body obesity, a rounded face, fat around the neck and thin arms and legs. PCOS is a condition that affects about 5-10 percent of women of childbearing age. Women who have PCOS often are obese, have excess hair growth and have reproductive problems and other health issues. These problems are caused by high levels of hormones called androgens.
Certain medicines may cause you to gain weight. These medicines include some corticosteroids, antidepressants, and seizure medicines, which can slow the rate at which your body burns calories, increase your appetite, or cause your body to hold on to extra water. All of these factors can lead to weight gain.

Considering the harmful enviromental effects produced by pollution, overpopulation and depletion of natural resources, numerous scholars and public officials have called for increased urgency in motivating people to engage in pro-environmental behaviors. One significant way of meeting such calls involves our behavior as consumers. For example, people often have the option of switching from conventional products to energy-efficient or reusable "green" products. Yet, while green options are becoming more widely available, many barriers to change remain. For instance, people are notoriously reluctant to change familiar patterns of behavior and making a switch to green behaviors often necessitates making sacrifices (e.g, paying more for a less effective product)
Based on research on energy conservation in the wake of the 1970s energy crisis, researchers have continued to investigate strategies that promote conservation behaviors. However, they need to consider the underlying motives for conservation in order to develop an effective strategy. In fact, those motives have been identified. Each of them suggests different strategies for stimulating conservation. Therefore, public officials should choose one best strategy to conserve environment.
According to an enviromental concern perspective, people are assumed to engage in conservation primarily because they, at some level, basically care about the security of the planet and its inhabitants. To motivate green behavior from this perspective, an effective strategy involves better informing people about the plight of the environment. Accordingly, information campaigns about the dangerous state of the planet should lead people to behave in a pro-enviromental fashion, even if going green requires some sacrifice on the part of consumers. In contrast, a rational economic perspective suggests that conservation is primarily determined by economic reasons. As a result, an effective way to motivate people to go green is by making green products cheaper, more efficient and providing consumers with financial incentives (e.g.,tax breaks) to buy them. The motives related to environmental concern and economic advantage can certainly spur conservation

The applications, games and websites that are promoted as 'educational' are not always the best ones for supporting learning. The fact that they are interactive does not necessarily mean that they are much better than old-fashioned workbook with its right and wrong answers. Children may enjoy these products for a while but then get a bit bored. Thus, they are not the most approriate or engaging way to learn.
Treat so-called 'free' applications with caution. Some will expose your child to advertisement. Others are designed to wait until your child is engaged in a game or storyline and then demand payment before they can go any further. This can lead to frustration as young children do not understand why they cannot continue. Sometimes it is better to make a small payment in advance if the application promises no further purchases. However, some applications are free to download and completely free of advertisement or in-app purchases.
Choosing an app needs the same kind of thought and care you would put into buying anything else for your child. Do not rely only on the star rating. Instead, read the user reviews and check the privacy policy if you are worried about the personal infomation that the app might be collecting. If you want your child enjoy learning, develop curiosity and think about things creatively, provide them with a range of games and apps. Open-ended games have become progressively more challenging and encourage children to explore and have fun. They are, therefore more likely to establish a love of learning and to lay the foundation for their future development
Physical activity, reading and other more 'traditional' activities continue to play a very important part in children's development. But, most parents do rely on screen devices from time to time to engage their child while they are busy with something else.This is not a problem in itself, just as long as children's time is made up of a balanced range of activities.
Regarding busy parent's reliance on sreen devices to help keep their children entertained, the author assumes that .....

Different forms of energy sources have helped us in many ways from running our vehicles to cooking at home or generating electricity. There are two types of energy sources-renewable and non-renewable energy resources. The former is where the energy resources do not get depleted and they can be used repeatedly whereas non-renewable energy resources cannot be used again and again.
We cannot even imagine a life without the existence of fossil fuels like crude oil; coal and natural gas. But, usage of these energy resources creates lot of problems. Global warming, increase in prices of fossil fuels, and the threat of peak oil are major concerns around the globe but what steps are we taking to overcome all these issues? If we stop consuming fossil fuels, we can stop global warming and save non renewable energy resources for our future generations to deploy. But, at the same time we need to seek an alternative to meet our requirements. We come across these topics on television, internet, and magazines and there is a lot of debate going on with regards to these topics. Is it possible for us to overcome the crisis? Only alternative energy solutions can help us as well as our environment to some extent.
Industries that deal with alternative energy solutions like solar and wind power thrive hard to save our environment. Even though modern technologies are being implemented to extract crude oil from places. Which were not reachable earlier, it is still nor possible to meet the growing demand. The demand for fossil fuels is increasing due to the rapid increase in population growth. Alternative energy -solutions have lot of benefits when compared to non-renewable energy resources. Industries have started investing their time and money in researching as well as setting up power plants.
Certain home users hesitate to go for alternative energy solutions as initial investment needs to be made. However, once the equipment is installed, there will be no maintenance costs or other repetitive costs. Apart from the set up cost, energy from the sun and the wind will always be free in any part of the country and there is no need for being dependent upon other countries. On the other hand, the prices of renewable energy resources keep increasing and certain countries have to dependent upon major oil producing countries. Home users who consume alternative energy resources can cut down on their electricity bills.
Every system has its own pros and cons but the best and wise thing to do is weigh the options that are available and choose the energy resources that offers long-term benefits. When it comes to alternative energy solutions, setting up solar plants and building windmills is a huge and complicated process but once they are set up, they offer endless benefits. In case of fossil fuels, oil companies need to locate the proven reserves, dig oil wells, extract oil, and convert into a more usable from so that it can reach the end consumer.

The food stimulating a suspicion is on course for inspiring even more wonder from a medical standpoint as scientists have reported the latest evidence that chili peppers are a heart-healthy food with potential to protect against the no. 1 cause of death in the developed world. The report was part of the 243rd National Meeting and Exposition of the American Chemical Society (ACS).
The study focused on capsaicin and its fiery-hot relatives, a spicy family of substances termed “capsaicinoids”. As the stuff that gives cayennes, jalapenos, habaneros and other chili peppers their heat, capsaicin already has an established role in rub-on-the-skin creams to treat arthritis and certain forms of pain. Past research suggested that spicing food with chilies can lower blood pressure in people with that condition, reduce blood cholesterol, and ease the tendency for dangerous blood clots to form.
“Our research has reinforced and expanded knowledge about how these substances in chilies work in improving heart health,” said Zhen-Yu Chen, who presented the study. “ We now have a clearer and more detailed portrait of their innermost effects on genes and other mechanism that influence cholesterol and the health of blood vessels. It is among the first research to provide that information. “ The team found, for instance, that capsaicin and a close chemical relative boost heart health in two ways. They lower cholesterol levels by reducing accumulation of cholesterol in the body and increasing its breakdown and excretion in the feces. They also block action of a gene that makes arteries contract, restricting the flow of blood to the hearts and other organs. The blocking action allows more blood to flow through blood vessels.
“We conclude that capsaicinoid were beneficial in improving a range of factors related to heart and blood vessel health,” said Chen, a professor of food and nutritional science at the Chinese University of Hong Kong. “But we certainly do not recommend that people start consuming chilies to an excess. A good diet is a matter of balance. And remember, chilies are no substitute for the prescription for meditations proven to be beneficial. They may be a nice supplement, however, for people who find the hot flavour pleasant”.
Chen and his colleagues turned to hamsters for the study, animals that serve as stand-ins for humans in research that cannot be performed in people. They gave the hamsters high-cholesterol diets, divides them into groups, and supplemented each group’s food with either no capsaicinoids in the control group or various amounts of capsaicinoids. The scientists then analysed the effects.
In addition to reducing total cholesterol levels in the blood, capsaicinoids reduced levels of the so-called “bad” cholesterol which deposits into blood vessels, but did not affect levels of so-called “good” cholesterol. The team found indications that capsaicinoids may reduce the size of deposits that already have formed in blood vessels, narrowing arteries in ways that can lead to heart attacks or strokes.
Capsaicinoids also blocked the activity of a gene that produce cycloosygenase-2, a substance that makes the muscles around blood vessels tighten. By blocking it, muscles can relax and widen, allowing more blood to flow.
Another way to restate ideas in the last paragraph of the passage is ...

The present study sought to document the word reading and comprehension levels attained by children who were implanted by 5 year of age. It was hypothesized that the improved speech perception abilities acquired with cochlear implantation would promote phonological coding skills. (1)…
Three subtests of diagnostic reading assessment batteries standardized on hearing children were administered to 181 children between 8 year 0 month and 9 year 11 month of age who had 4 to 6 years of implant experience. (2) … It included a lexical decision task, a rhyme task, and the digit span subtests of the Wechsler Intelligence Scale for Children.
Over half of the children scored within the average range for their age compared with the normative data for hearing children. (3) … They were higher nonverbal intelligence, higher family socio-economic status, and later onset of deafness between birth and 36 months.
