Policy Analysis - Essay Example The most fundamental obligation of Homeland Security is to secure and protect the American people. It is the duty and policy of Homeland Security to guide the nation as they commit themselves to achieve a more protected Homeland, which can sustain the people’s way of life. George Bush outlined the range of homeland security threat based on the opening recommendations of National Strategy for Homeland Security. The document provided a good example of how to create public policy (Forest, 2006, p.132). The executive branch of government had to inspect and identify the weaknesses and strengths of Homeland Security. The strengths and weaknesses were identified based on prevention, recovery, protection, deterrence and response. After the identification, the formulated policies intensified the emerging problems leading to the creation of the strategy. The influences of such articles are crucial and should be guarded. It is a statement of purpose without the force of law. The strategy of Homeland Security points out to congress to put on more efforts to work together with homeland security. The congress should not depend on Homeland Security; instead, it should take steps to deliver its responsibilities with respect to protection of the American people and the Homeland. The statement has salient points and the powers required in turning policy into law. It also acts as a reminder on how the president’s powers are delivered to the zenith as they are channelled to legislative and executive branches at the same time. It is extremely valuable to look in detail the roles of the three branches of government in addressing homeland security threats like illegal immigration, street gangs, terrorism, gun ownership, and sale of illegal drugs. Global war on terrorism has triggered the acts relating to how the enemy combatants are treated by use of military operations, conducting local intelligence, and military tribunals. The congress passed a resolution as a respons e to the 9/11 attacks and the continued threat and attacks posed by terrorists (Forest, 2006, p.140). The resolution gave the president powers to apply and emphasize his powers as commander in chief. The president authorizes the use of the necessary force against organizations, persons who planned, committed, and aided the attacks, which occurred in 2001. In addition, under the law, the congress authorises and gives its formal and constitutional powers. In this regard, the United States Army plays the role of defending the national security. This is against continuing threats posed by Iraq and other relevant council resolutions. The president played a role in establishing Iraq’s support of national terrorism. The United States has a long history and valued tradition of welcoming visitors without restrictions. The attacks of 2001 made United States be more cautious because they realise that some visitors come to the United States to raise funds for terrorist activities, and co mmit terrorist acts. It is the responsibility of United States to prevent foreigners with the intent of committing the terrorist attacks. In addition, they should deport, detain, and prosecute other aliens with the same intentions but are residing in the country. After 9/11, the attention of United States enforcement and administration of immigration policy increased (Forest, 2006, 148). The legislation regarding enforcement and a

Molecular basis of aging in relation to fertility Essay

Molecular basis of aging in relation to fertility - Essay Example Aging is defined as â€Å"a progressive, time-dependent deterioration of an organism’s capacity to respond to environmental changes, which ultimately makes it susceptible to death† (Allen and Balin 4). It is a widely-accepted idea that aging is a natural process that occurs in all living organisms. Since the process of aging most likely would be affecting an organism’s overall body functions, it would also greatly affect its capacity to reproduce, eventually leading to a decrease or the loss of fertility of the said organism (Liu and Case 1169). At present, there are numerous links between chromosomal and DNA damage not just to the aging process of an organism but also on fertility. A female’s capacity to conceive and give birth, or a male’s capability to contribute in conceiving a child is called fertility (Masoro 161). In order to proliferate the species well into numerous and succeeding generations, organisms must be able to produce as much offsp ring as possible that are able to adapt to the current environment that they live on. For that to happen, the process called natural selection takes place (Torday and Rehan 12). Also, the energy that flows within the organism is appropriated in such a way that during the process of reproduction, most of the energy from the consumption of food is distributed to the body’s reproductive systems, mostly to the rapidly-dividing cells called the gametes. However, once the organism starts the process of aging, the energy being exerted for reproduction is reduced and more focus is given to the maintenance of the organism’s body, especially when there is the presence of a rapid breakdown of cells as well as the decline of cell-to-cell communication within the systems and organs (13). Not only is the production of cells affected by aging, but also the process of DNA replication and repair as well. Due to the proliferation of damaged DNA especially in the sex cells of the organis m, it would eventually contribute to the creation of deformed or dysfunctional oocytes or spermatozoa that would eventually be the cause of the loss of reproductive capability or infertility among aging organisms (Sikka 78). Among pregnant women, the imbalance of antioxidants and pro-oxidants may result to oxidative stress due to reactive oxygen species (ROS), which could affect DNA production when in excess, or affect cell-signaling pathways when deficient (Dupont, Cordier and Junien 25). Also, due to the age-associated decline of female fertility can be attributed to the abnormalities found in the oocytes themselves. Due to the abnormalities in the folding of the DNA and eventually, the abnormalities in the alignment of the chromosomes during meiosis and diakinesis which can be attributed to the mutations in the microtubules, preimplantation of embryos or aneuploidy in the fertilized egg may cause spontaneous abortions among older pregnant females (The Practice Committee of the Am erican Society for Reproductive Medicine (PCASRM) 248). Male fertility is also greatly affected by ROS, wherein the spermatozoa membranes would be highly-susceptible to oxygen damage due to the peroxidation of lipid membranes, damaging the sperm and rendering them incapable of fertilizing the ovum (Sikka 78). Also, the presence of errors in the DNA called nicks could also contribute to male infertility due to loosely-packed DNA and chromatin disorganization (Sakkas, Urner and Bizzaro 11). These nicks may be attributed to age-induced DNA
