China's one-child policy was intended to slow population growth but also skewed the country's gender balance by encouraging sex-selective abortions if the first child was female. However, the policy was not strictly one-child and allowed second or third children in many areas. Recent data shows that Chinese families with multiple children disproportionately contribute to the gender imbalance by favoring sons for second children through sex-selective abortions if the first child is female. Economic reforms in China may have also encouraged the gender imbalance by giving women more ability to determine fetal sex. Loosening the one-child policy may not correct the imbalance since the preference exists for families to have both a son and a daughter.
China has officially abandoned its One Child Policy amid deepening demographic crisis of shrinking workforce and aging population in the world’s second largest economy.
The new law allows couples to have two children from January 1, 2015 and marks the ending its over three decades old One Child Policy.
During the 1940’s the Chinese government encouraged people to have large families, to gain military strength and for the people to help with agricultural production led to OVERPOPULATION in china.

Therese Hesketh, One Child Policy: impacts on reproductive health and attitudesWellcome Collection
Since its introduction in 1979, the one child policy has had a direct impact on the lives of over one-fifth of the world’s population. The policy has influenced reproductive choice, preferred family size and access to abortion. In a country where preference for male offspring is common, and where there is easy access to abortion, it has also contributed to an excess of male births. Some relaxation of the policy has started, and this is expected to continue.

Teen pregnancy in the United States
Teen pregnancy in the United States
The National Campaign to Prevent Teen Pregnancy was founded in 1996 and has its headquarters in Washington D.C. and has nearly 200 organizations and media outlets which serve as partners. The National Campaign to Prevent Teen and Unplanned Pregnancy’s main agenda seeks to improve the lives and future prospects of children and families by ensuring that children are born into stable, two-parent families who have a commitment to and are ready for the demanding task of raising the next generation. Their strategy is aimed at the prevention of teen pregnancy and unplanned pregnancy among single, young adults by supporting a combination of responsible values and behavior by both men and women and responsible policies in both the public and private sectors. Their actions are aimed at improving child and family well-being therefore reducing the prevalence rate of poverty by providing more opportunities for the teenagers to complete their education or achieve other life goals while advocating for fewer abortions towards the creation of a stronger nation.
Teenage pregnancies have resulted to a total of 273,105 babies who were born to women aged 15–19 years, for a live birth rate of 26.5% per 1,000 women in this age group. There has been a decline in teen pregnancies with a drop of 10% in 2013. The birth rates declined at 13% for women aged 15–17 years, and 8% for women aged 18–19 years (Child Trends, 2014). Still, the U.S. teen pregnancy rate is substantially higher than in other western industrialized nations (Clay, et al, 2012). The national teen pregnancy rate has been declining steadily over the last two decades which has been attributed to the combination of an increased percentage of adolescents who are waiting to have sexual intercourse and the increased use of contraceptives by teens. The teen pregnancy rate includes the pregnancies that end in a live birth, as well as those that end in abortion or miscarriage resulting from fetal loss. In the United States 4 in 10 teens get pregnant at least once before they reach the age of 20 which leads to the teenagers dropping out of school with more than 50% of teen mothers never completing school. The trends show that less than 10% of the fathers marry the mother of their child and that almost a half of the teen mothers get their second child within the first 24 months since 80% of teens who do not use protective methods have higher chances of becoming pregnant.
Teen birth rates have been declining significantly in the recent years, however, despite these declines, there still exists a lot of disparities that need to be properly addressed (Dessen, 2005). There are substantial disparities that persist in teen birth rates, and teen pregnancy and childbearing which continue to carry significant social and economic costs. In 2013, the Hispanic teen birth rates were still more than two times higher than the rate for ...
A case study about Teenage pregnancy which is a widespread problem all over the world. Teen pregnancy and childbearing bring substantial social and economic costs through immediate and long-term impacts on teen parents and their children.

Pulmonary Thromboembolism - etilogy, types, medical- Surgical and nursing man...VarunMahajani
Disruption of blood supply to lung alveoli due to blockage of one or more pulmonary blood vessels is called as Pulmonary thromboembolism. In this presentation we will discuss its causes, types and its management in depth.
Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

1. China's One-Child Policy Isn't
So Straightforward

Last week China released new census data showing that Chinese
families favour sons over daughters. In 2014, according to the data,
Chinese women gave birth to 115.9 boys for every 100 girls. (The
natural human birth ratio is around 105 boys to every 100 girls.)
Skewed gender ratios of this sort date back to the early 1980s, and the
impact has been cumulative. China now has 33 million more men than
women, tens of millions of whom may never be able to find mates. The
Chinese government has recently attempted to alter this dynamic by
loosening its family planning policies. But new research suggests that
this well meaning policy shift could be counter-productive.

China's so-called one-child policy was initiated in the early 1980s
with the goal of slowing the country's population growth.
According to the prevailing narrative, it also had the effect of
skewing the country's gender balance. The policy is said to have
encouraged expectant parents who harboured a traditional
preference for sons over daughters to seek out ultrasounds and -if
a girl was expected -to pursue sex selective abortions. In that
sense, Chinese President Xi Jinping's loosening of the one child
policy in November 2013 might reasonably be expected to begin
correcting the country's gender imbalance.
But the demographic effects of the one-child policy were never so
straightforward. Except for its first few years, the policy allowed
parents to have second and third (and more) children, depending
on where in China they lived. A 2010 study revealed that 65% of
Chinese parents, mostly concentrated in rural areas, were subject
to “one-plus“ child policies, whereby a second, or even a third
child, was permitted. In certain provinces parents were allowed to
have a second child if their first child was a girl -thereby reducing
the incentive to abort a first baby for gender reasons.

Census data reveals, however, that Chinese families with multiple
children have made a disproportionate contribution in recent years to
the country's gender imbalance. According to an analysis of census data
from 2000, 51.5% of first children surveyed were boys -a nearly normal
sex ratio. But in those cases where a first child was a girl, 62% of the
children who followed were sons -a completely unnatural ratio. And, in
those cases where families had two daughters, the likelihood that a
third child would be a son was 70%.
The phenomenon isn't just confined to the 2000 census. A 2009 study
of Chinese census data taken in 2005 showed that second born children
had an average sex ratio of 146 boys to 100 girls (and, in nine provinces
it exceeded 160 to 100) while first children, again, had nearly normal
sex ratios. And as recently as 2011, the Chinese province of
Heilongjiang reported a sex ratio of 113.45 to 100 for second order
births and 147 to 100 for third order births. In all cases, it's second
children -not the first born children that one would assume would be
most affected by the one-child policy -that make the greatest
contribution to China's unbalanced sex ratio.

What explains this phenomenon? At least two studies have shown that families
allowed to have two-children maintain a preference for boys that co-exists with a
de sire for a male female mix (a male-male mix is less desirable). In other words: if
a couple desires a boy and a girl -as many Chinese apparently do -the least
emotionally draining ally and financially draining means of ensuring that outcome is
to allow nature to take its course with the first child, and sex select as necessary
with the second.
But if China's family planning policies didn't create the gender imbalance, what
did? Research suggests that China's liberalizing economic reforms of the 1970s and
1980s -reforms that were initiated around the same time as the one-child policy -
may be responsible, by providing Chinese women with the economic means to
travel and pay for ultrasounds (and sex selective abortions). According to a 2014
study , women in China with high school educations (and, presumably , more
earning power) were 7.4% more likely to have a boy as their second child than
women with no formal schooling while sex ratio imbalances were most pronounced
in counties with the greatest growth in economic output.
