The economy of Brazil is in the top ten largest economies along with the United States. It is the biggest in Latin America. Actually it is the seventh largest in the world. Brazil has used its newly found economic mechanism to syndicate its outcome in South America and show more of a role in the Global Businesses. The Obama Administration’s National Security Strategy recognizes Brazil as a developing center of effect, and greets the management of the country’s joint and global issues. The United States and Brazil associations mostly have been good in the recent years. But Brazil has other strengthening relations with neighboring countries and expanding ties with nontraditional partners in the South that’s developing.

The P.E.R.I.E. process is illustrated in this case by the steps taken to address the issue of smoking rates in adults, being impacted by the rise in adolescent smoking behaviors. The first step of this process is the Problem. In this case, the text indicates, the problem is the growth rate of smoking teens in the 80’s and 90’s (Riegelman & Kirkwood, 2015). This in turn, led to an increase in adult smokers. This would raise rates again, after previously lowering them by approximately 50% (Riegelman & Kirkwood, 2015). The next step is Etiology. In this step we correlate smoking with cancer and the rise of adult smoking rates with the growth of adolescent smoking rates. This in turn, correlates adolescent cigarette smoking, to the rises in cancer (morbidity), and deaths from cancer (mortality). The case study also states, “…it was also found that nearly 90% of those who smoked started before the age of 18…” (Riegelman & Kirkwood, 2015). It was determined through behavior modification (preventing adolescent smoking), the rate of adult smokers would reduce. Thus, recommendations were introduced. The case study reveals, adolescents were targeted in cigarettes advertisements and marketing (Riegelman & Kirkwood, 2015). Cigarette availability was also an issue. Implementations of sales and advertisement campaign policies, were altered in reference to miners. The text reveals, once evaluated, strategies to reduce adolescent smoking

Smoking during the first trimester of pregnancy could lead to the placenta not developing fully. As the placenta carries oxygen and blood to the foetus this may impair growth and link to low birth weights. Babies born to smoking mothers are 30% more likely to have a premature baby which could lead to respiratory distress, problems feeding and they could have difficulty regulating their body temperature. Babies undergo withdrawal like systems and tend to be more jittery and harder to settle. Babies being brought up in a smoking household are at increased risk of cot death and may go on to develop asthma during childhood.

Through the use of graphical descriptive techniques to assess the data provided, BAD has constructed a scatter diagram to describe several key variables of the data. The first of these diagrams is the correlation between the lengths of stay and

Let us first examine the apparent effect of mother’s marital status during childbearing on infants’ weight by running a simple regression analysis where we use “married” as a dummy variable and child’s birth weight as a dependent variable. We have the following results:

c) What is the null and alternative hypothesis? Do the data results lead you to reject or fail to reject the null hypothesis?

While evaluating and analyzing the issue of smoking, various models and systems could be used. Healthy People 2020 use information analyzed from national census data of events such as the National Vital Statistics System. It also uses data from nationally representative sample surveys for example the National Health Interview survey. Data on the relationship between maternal behavior and birth weight, maternal and child health and vital statistics derived from The Pregnancy Risk Assessment Monitoring System (PRAM) can also be

Marashi-Pour et al. (2015) investigated the link between the amount of tobacco outlets and neighbourhood socioeconomic status. They also examined the association between the amount of neighbourhood tobacco outlets and individual smoking status, and the amount of tobacco outlets in New South Wales (NSW) that surround primary and secondary schools. Marashi-Pour et al. (2015) used kernel density estimation with an adaptive bandwidth to compute the mean density of retail tobacco outlets registered in NSW from 2009-11 (p. 1). In order to investigate the association between socioeconomic status and density of tobacco outlets, Marashi-Pour et al. (2015) utilised a generalised ordered logistic regression model. Random-intercept generalised linear mixed

Smoking during pregnancy is associated with many adverse outcomes for children as well as negative consequences for child health and development. Maternal smoking late in pregnancy reduces birth weight and size. Babies that are born to habitual smokers "weigh, on average, about 9 oz. less, and are shorter both at birth and in the years to come" (Berger 115). Nicotine is the addictive ingredient in cigarettes and breaking that habit can be nearly impossible for some women. What is the acceptable way for her to stop smoking? It's my opinion a woman needs to gather all of the information she can and then discuss her options

Among the many environmental factors that can affect infant learning, prenatal cigarette exposure has proven to be a topic of interest in behavioral teratology due to the large number of health effects it is associated with. Some of the health effects of prenatal cigarette exposure include: lower birth weight, smaller head circumference, lower IQ, attention dysfunction, hyperactivity and other conduct problems, as well as school failure (Mezzacappa, E., 2011, p. 881-891). There are some human studies that investigate the cognitive deficits related to prenatal cigarette exposure which include: auditory, visual attention, and working memory issues.

(16) a baby's birth-weight is dependent on sufficient nutrition throughout gestation, newer studies suggest under-nutrition causes compensatory growth, which preserves full growth of some tissues and sacrifice others. This leads to programming and altered gene expression affecting metabolism and physiological settings. The systems which have been observed to be affected by programming in adulthood include the immune system, neuro-endocrine settings and stem cell quality increasing risk of diabetes type 2, hypertension and heart disease.
