Please answer the following question: Information: - Public health refers to "the science and art of preventing disease, prolonging life and promoting human health through organized efforts and informed choices of society, organizations, public and private, communities and individuals." It is concerned with threats to health based on population health analysis. The population in question can be as small as a handful of people, or as large as all the inhabitants of several continents (for instance, in the case of a pandemic). The dimensions of health can encompass "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity," as defined by the United Nations' World Health Organization. Public health incorporates the interdisciplinary approaches of epidemiology, biostatistics and health services. Environmental health, community health, behavioral health, health economics, public policy, insurance medicine, mental health and occupational safety and health are other important subfields. - Geriatrics or geriatric medicine is a specialty that focuses on health care of elderly people. It aims to promote health by preventing and treating diseases and disabilities in older adults. There is no set age at which patients may be under the care of a geriatrician or geriatric physician, a physician who specializes in the care of elderly people. Rather, this decision is determined by the individual patient's needs, and the availability of a specialist. It is important to note the difference between geriatrics, the care of aged people, and gerontology, which is the study of the aging process itself. The term "geriatrics" comes from the Greek "geron" meaning "old man", and "iatros" meaning "healer". However, geriatrics is sometimes called medical gerontology. - Thought refers to ideas or arrangements of ideas that are the result of the process of thinking. Though thinking is an activity considered essential to humanity, there is no general consensus as to how we define or understand it. - Harvard University is a private Ivy League research university in Cambridge, Massachusetts, established in 1636, whose history, influence, and wealth have made it one of the world's most prestigious universities. - A liberal arts college is a college with an emphasis on undergraduate study in the liberal arts and sciences. A liberal arts college aims to impart a broad general knowledge and develop general intellectual capacities, in contrast to a professional, vocational, or technical curriculum. Students in a liberal arts college generally major in a particular discipline while receiving exposure to a wide range of academic subjects, including sciences as well as the traditional humanities subjects taught as liberal arts. Although it draws on European antecedents, the liberal arts college is strongly associated with American higher education, and most liberal arts colleges around the world draw explicitly on the American model. - Social work is an academic and practice-based professional discipline that seeks to facilitate the welfare of communities, individuals, families, and groups. It may promote social change, development, cohesion, and empowerment. Underpinned by theories of social sciences and guided by principles of social justice, human rights, collective responsibility, and respect for diversities, social work engages people and structures to address life challenges and enhance well-being. - A policy is a deliberate system of principles to guide decisions and achieve rational outcomes. A policy is a statement of intent, and is implemented as a procedure or protocol. Policies are generally adopted by the Board of or senior governance body within an organization where as procedures or protocols would be developed and adopted by senior executive officers. Policies can assist in both "subjective" and "objective" decision making. Policies to assist in subjective decision making would usually assist senior management with decisions that must consider the relative merits of a number of factors before making decisions and as a result are often hard to objectively test e.g. work-life balance policy. In contrast policies to assist in objective decision making are usually operational in nature and can be objectively tested e.g. password policy. - Collegiate Gothic was an architectural style subgenre of Gothic Revival architecture, popular in the late-19th and early-20th centuries for college and high school buildings in the United States and Canada, and to a certain extent Europe. A form of historicist architecture, it took its inspiration from English Tudor and Gothic buildings. - Nursing is a profession within the health care sector focused on the care of individuals, families, and communities so they may attain, maintain, or recover optimal health and quality of life. Nurses may be differentiated from other health care providers by their approach to patient care, training, and scope of practice. Nurses practice in many specialisms with differing levels of prescriber authority. Many nurses provide care within the ordering scope of physicians, and this traditional role has shaped the public image of nurses as care providers. However, nurses are permitted by most jurisdictions to practice independently in a variety of settings depending on training level. In the postwar period, nurse education has undergone a process of diversification towards advanced and specialized credentials, and many of the traditional regulations and provider roles are changing. - A research university is a university that expects all its tenured and tenure-track faculty to continuously engage in research, as opposed to merely requiring it as a condition of an initial appointment or tenure. Such universities can be recognized by their strong focus on innovative research and the prestige of their brand names. On the one hand, research universities strive to recruit faculty who are the most brilliant minds in their disciplines in the world, and their students enjoy the opportunity to learn from such experts. On the other hand, new students are often disappointed to realize their undergraduate courses at research universities are overly academic and fail to provide vocational training with immediate "real world" applications; but many employers value degrees from research universities because they know that such coursework develops fundamental skills like critical thinking. - The welfare state is a concept of government in which the state plays a key role in the protection and promotion of the social and economic well-being of its citizens. It is based on the principles of equality of opportunity, equitable distribution of wealth, and public responsibility for those unable to avail themselves of the minimal provisions for a good life. The general term may cover a variety of forms of economic and social organization. The sociologist T.H. Marshall described the modern welfare state as a distinctive combination of democracy, welfare, and capitalism. - Social policy is a term which is applied to various areas of policy, usually within a governmental or political setting (such as the welfare state and study of social services). - John B. Williamson is a Professor of Sociology who specializes in gerontology , social policy and social welfare.He joined the faculty of the Department of Sociology at Boston College in 1969 after completing his Ph.D. in social psychology at Harvard University . He is also affiliated with the Center for Retirement Research at Boston College and the Sloan Center on Aging & Work at Boston College . Over the course of his career professor Williamson has published 16 books and well over 100 journal articles and book chapters . - Massachusetts ; officially the Commonwealth of Massachusetts, is the most populous state in the New England region of the northeastern United States. It is bordered by the Atlantic Ocean to the east, the states of Connecticut and Rhode Island to the south, New Hampshire and Vermont to the north, and New York to the west. The state is named for the Massachusett tribe, which once inhabited the area. The capital of Massachusetts and the most populous city in New England is Boston. Over 80% of Massachusetts' population lives in the Greater Boston metropolitan area, a region influential upon American history, academia, and industry. Originally dependent on agriculture, fishing and trade, Massachusetts was transformed into a manufacturing center during the Industrial Revolution. During the 20th century, Massachusetts' economy shifted from manufacturing to services. Modern Massachusetts is a global leader in biotechnology, engineering, higher education, finance, and maritime trade. - The Association of Jesuit Colleges and Universities (AJCU) is a consortium of the 28 Jesuit colleges and universities and two theological centers in the United States committed to advancing academic excellence by promoting and coordinating collaborative activities, sharing resources, and advocating and representing the work of Jesuit higher education at the national and international levels. It is headquartered in Washington, D.C. and led by the Association's president, Rev. Michael J. Sheeran, S.J.. - Boston College (also referred to as BC) is a private Jesuit Catholic research university located in the village of Chestnut Hill, Massachusetts, United States, west of downtown Boston. It has 9,100 full-time undergraduates and almost 5,000 graduate students. The university's name reflects its early history as a liberal arts college and preparatory school (now Boston College High School) in Boston's South End. It is a member of the 568 Group and the Association of Jesuit Colleges and Universities. Its main campus is a historic district and features some of the earliest examples of collegiate gothic architecture in North America. - Feeling is the nominalization of the verb "to feel". The word was first used in the English language to describe the physical sensation of touch through either experience or perception. The word is also used to describe experiences other than the physical sensation of touch, such as "a feeling of warmth" and of sentience in general. In Latin, "sentire" meant to feel, hear or smell. In psychology, the word is usually reserved for the conscious subjective experience of emotion. Phenomenology and heterophenomenology are philosophical approaches that provide some basis for knowledge of feelings. Many schools of psychotherapy depend on the therapist achieving some kind of understanding of the client's feelings, for which methodologies exist. - A campus is traditionally the land on which a college or university and related institutional buildings are situated. Usually a college campus includes libraries, lecture halls, residence halls, student centers or dining halls, and park-like settings. - Chestnut Hill is an affluent New England village (of Newton) located six miles (10km) west of downtown Boston, Massachusetts, United States. Like all Massachusetts villages, Chestnut Hill is not an incorporated municipal entity. Unlike most Massachusetts villages, it encompasses parts of three separate municipalities, each located in a different county: the town of Brookline in Norfolk County; the city of Boston in Suffolk County (parts of its neighborhoods of Brighton and West Roxbury), and the city of Newton in Middlesex County. Chestnut Hill's borders are roughly defined by the 02467 ZIP Code. Chestnut Hill is not a topographical designation; the name refers to several small hills that overlook the 135-acre (546,000 m) Chestnut Hill Reservoir rather than one particular hill. Chestnut Hill is best known as the home of Boston College, part of the Boston Marathon route, as well as the Collegiate Gothic canvas of landscape architect Frederick Law Olmsted. - Social psychology is the scientific study of how people's thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. In this definition, "scientific" refers to the empirical method of investigation. The terms "thoughts", "feelings", and "behaviors" include all psychological variables that are measurable in a human being. The statement that others' presence may be "imagined" or "implied" suggests that we are prone to social influence even when no other people are present, such as when watching television, or following internalized cultural norms. Social psychologists typically explain human behavior as a result of the interaction of mental states and immediate social situations. - Psychology is the study of behavior and mind, embracing all aspects of conscious and unconscious experience as well as thought. It is an academic discipline and a social science which seeks to understand individuals and groups by establishing general principles and researching specific cases. In this field, a professional or researcher is called a psychologist and can be classified as a social, behavioral, or cognitive scientist. Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the physiological and biological processes that underlie cognitive functions and behaviors. Psychologists explore behavior and mental processes, including perception, cognition, attention, emotion (affect), intelligence, phenomenology, motivation (conation), brain functioning, and personality. This extends to interaction between people, such as interpersonal relationships, including psychological resilience, family resilience, and other areas. Psychologists of diverse orientations also consider the unconscious mind. Psychologists employ empirical methods to infer causal and correlational relationships between psychosocial variables. In addition, or in opposition, to employing empirical and deductive methods, someespecially clinical and counseling psychologistsat times rely upon symbolic interpretation and other inductive techniques. Psychology has been described as a "hub science", with psychological findings linking to research and perspectives from the social sciences, natural sciences, medicine, humanities, and philosophy. While psychological knowledge is often applied to the assessment and treatment of mental health problems, it is also directed towards understanding and solving problems in several spheres of human activity. By many accounts psychology ultimately aims to benefit society. The majority of psychologists are involved in some kind of therapeutic role, practicing in clinical, counseling, or school settings. Many do scientific research on a wide range... - Gerontology (from the Greek , "geron", "old man" and -, "-logia", "study of"; coined by Ilya Ilyich Mechnikov in 1903) is the study of the social, cultural, psychological, cognitive, and biological aspects of aging. It is distinguished from geriatrics, which is the branch of medicine that specializes in the treatment of existing disease in older adults. Gerontologists include researchers and practitioners in the fields of biology, nursing, medicine, criminology, dentistry, social work, physical and occupational therapy, psychology, psychiatry, sociology, economics, political science, architecture, geography, pharmacy, public health, housing, and anthropology. - Sociology is the study of social behaviour or society, including its origins, development, organization, networks, and institutions. It is a social science that uses various methods of empirical investigation and critical analysis to develop a body of knowledge about social order, disorder, and change. Many sociologists aim to conduct research that may be applied directly to social policy and welfare, while others focus primarily on refining the theoretical understanding of social processes. Subject matter ranges from the micro-sociology level of individual agency and interaction to the macro level of systems and the social structure. - The Ivy League is a collegiate athletic conference comprising sports teams from eight private institutions of higher education in the Northeastern United States. The conference name is also commonly used to refer to those eight schools as a group beyond the sports context. The eight institutions are Brown University, Columbia University, Cornell University, Dartmouth College, Harvard University, the University of Pennsylvania, Princeton University, and Yale University. The term "Ivy League" has connotations of academic excellence, selectivity in admissions, and social elitism.
