2. Researchers conducted an international study of school bullying in relation to family income. They surveyed 162,305 students aged 11, 13, and 15 at 5,998 schools in 35 countries. The
researchers found that within each school, students from lower-income families were bullied
more frequently than students from higher-income families. But, they did not find a higher
frequency of bullying in lower-income schools or countries. In fact, the most bullying took place in
schools and countries with the widest range of incomes or the the widest economic inequality.
Analyze this research on bullying in relation to the following questions:
• What research method was used in the study?
• What kind of data was collected (qualitative or quantitative)?
• What is one advantage of that research method for this study? What is one disadvantage?
• What does it mean to ask whether the survey had validity?
• What is one public policy issue that might be affected by the results of this research?

all the above is what i would say

yes. i think it is for sure.

    however, coronary heart disease , or chd, is actually a result of coronary artery disease, or cad, said edward a. fisher, m.d., ph.d., m.p.h., an american heart association volunteer who is the leon h. charney professor of cardiovascular medicine and also of the marc and ruti bell vascular biology and disease program at the nyu school of medicine.

  with coronary artery disease, plaque first grows within the walls of the coronary arteries until the blood flow to the heart’s muscle is limited. view an illustration of coronary arteries. this is also called ischemia. it may be chronic, narrowing of the coronary artery over time and limiting of the blood supply to part of the muscle. or it can be acute, resulting from a sudden rupture of a plaque and formation of a thrombus or blood clot.

    the traditional risk factors for coronary artery disease are high ldl cholesterol, low hdl cholesterol, high blood pressure, family history, diabetes, smoking, being post-menopausal for women and being older than 45 for men, according to fisher. obesity may also be a risk factor.

    “coronary artery disease begins in childhood, so that by the teenage years, there is evidence that plaques that will stay with us for life are formed in most people,” said fisher, who is former editor of the american heart association journal, atvb. “preventive measures instituted early are thought to have greater lifetime benefits. healthy lifestyles will delay the progression of cad, and there is hope that cad can be regressed before it causes chd.”

  living a healthy lifestyle that incorporates good nutrition, weight management and getting plenty of physical activity can play a big role in avoiding cad.

    “coronary artery disease is preventable,” agreed johnny lee, m.d., president of new york heart associates, and an american heart association volunteer. “typical warning signs are chest pain, shortness of breath, palpitations and even fatigue.” if you feel any of these symptoms, don’t delay — call 9-1-1.
