Q: Article: Girls who get enough dairy products in their diets may weigh less than other teens with the same age. Girls who consumed more dairy products were found to have slimmer middles than girls of the same age and race who ate the same number of calories and got the same amount of exercise. Girls who drank more soda, but also ate the same total calories, tended to be heavier. The newly reported study included 323 white and Asian girls between the ages of 9 and 14. A number of studies, mostly in adults, have shown that calcium may be key in maintaining normal body weight and fat stores. One reason may be the nutrient's effects on hormones that help store calories as fat. In the new study, reported in the Journal of Nutrition, calcium from dairy sources, but not non-dairy foods, was related to lower weight and less abdominal fat--the link was particularly strong among girls of Asian decent , who made up 47 percent of the study group. This suggests that "the dairy ingredient of the calcium intake is the key factor," write the study authors, led by Dr. Rachel Novotny of the University of Hawaii in prefix = st1 /Honolulu. It's possible, they explain, that other nutrients in milk play an important role in weight balance. For reasons that are unclear, the effect on body fat was stronger for Asian girls than for white girls, according to Novotny and her colleagues. They _ that ethnic differences in which dairy products are usually consumed, or in eating habits-having small amounts of dairy throughout the day, for instance, rather than a single large serving--may help explain the finding. According to the researchers, soda may increase pounds by adding calories to kid's diets, or by replacing milk. Milk, they note, has a range of nutrients, including protein and fat, which means it is metabolized ly slowly. Soda contains only sugar, which is quickly metabolized, easily causing hunger.

Q: Article: There is no doubt eCommerce is growing, and it will continue to grow. However, physical stores would not die as a result of the rise of eCommerce, at least not in the near future. The idea that eCommerce is taking over physical stores has already misguided many people. Physical stores are far from vanishing, and there are some solid reasons for it. The _ for online spending is optimistic with $150 billion expected to be spent in the coming three years, yet we are also expecting $300 billion in spending at physical stores in the same duration. Do you still think that physical-store shopping is too small to sustain the eCommerce blow? Even though consumers are staying away from physical stores that follow older concepts, yet we are seeing the rise of fresh concept stores all around the US. We are seeing innovative and attractive success stories of physical stores, ranging from clothes stores to restaurants to health spas. It would be easy to assume that this trend will continue. Indeed, many shopping malls are dying, yet there are still those shopping centers that are performing well. You can see this for yourself by visiting shopping malls near you. What I want to emphasize here is that not all shopping centers are made equal, just like not all eCommerce retailers are made equal. Both shopping malls and eCommerce sites can lose business if they fail to maintain productivity through improvements and innovations. When you visit shopping centers that are serious about their business, you would see their shops and parking lots packed. On the other hand, even e-tailers like Amazon have experimented with pop-up shopping concepts. It is important to bear in mind that consumers prefer face-to-face interactions instead of online interactions during shopping, meaning that physical stores are going to stay there. Still, eCommerce retailers are seeing all of their excitement disappear as they settle the sales tax problem associated with e-tailing. As of now, five states of America have already imposed sales tax on purchases through eCommerce sites, and e-tailers in those states have already witnessed 6 to 12 percent decrease in sales. This reinforces the fact that physical stores are here to stay, and if you are still undervaluing their growth, you are omitting a huge chunk of the retail representation.
Answer: Fresh concepts help build good business.

For another, governments of all countries should make laws on environmental protection.For example, banning the use of throw-away chopsticks and punishing illegal tree cutting. Scientists should also study and find ways to cut down the degree of its destruction and to improve the whole environment. How people look forward to sunny days with little breeze touching their faces now and forever!
