Its vividness and genial, bittersweet speculation help make it one of Frost's most popular poems, and because its shifts of metaphor and tone invite varying interpretation it has also received much critical discussion, not always admiring. The poem moves back and forth between two visual perspectives: birch trees as bent by boys' playful swinging and by ice storms, the thematic interweaving being somewhat puzzling. The birches bent "across the lines of straighter darker trees" subtly introduce the theme of imagination and will opposing darker realities.

Statement of Purpose – MHA

My country India, world’s largest democracy and home to over a billion fellow country men, has a very low Doctor to patient ratio and even lower Dentist to patient ratio. This led me to take my graduation in Dentistry. My days in Dental School often made me think about management of available resourses which involved simple insurence policies, hygienic practices than treating the diseases with an ensuing dramatic increase in the cost of such treatment that the people of my country can not afford. Healthcare administration in India is not covering even half the population let alone advanced medical aid. There might be great technological strides in the field of healthcare administration but the number of people benefited is only a select few. I was exposed to certain ground realities, like there are limited doctors and infrastructure which does not function to their optimum capacity and efficiency due to lack of proper management of limited resources. In my internship program I have seen many patients who were unable to get proper treatment due to lack of available human resourses and reimbursement. In my counrty there is no proper facility of maintaining patient records, online data storage and access of every patient health record. Even people do not have a clear cut idea of How to use insurance policies and reimbursement programmes. I was already doubting my future as a career dentist because my apparent inability to help large number of people In fact right from my under graduation Health care Administration is the primary interest of all my choices. In my under graduation I am very intuitive about management of human resources in the health care system, ethical and legal perspectives on malpractice,medical records, confidentially and required disclosures,reimbursement procedures, governmental regulation and legal restraints. All this factors guided me towads the MS in Helath care administration. In the present day environment, a sound understanding of fundamentals and expertise in a chosen field of interest is essential and I strongly believe that graduate school offers opportunities to attain the above.

This meaning that there are positive intentions in order to improve society or negative intentions by which society is not benefiting but the choices of the people. Conflict theory is the idea that society is composed of groups that are in perpetual conflict with one another for scarce resources.
