Robert Merton in his piece “Manifest and Latent and Dysfunctions” functions introduced the idea of both manifest and latent functions as social scientific concepts to help be used in a functional analysis. Both these functions effect the social institutions that an average person may interact with in normal daily life. Manifest functions are functions in which people intend to do and have knowledge of the outcome going into the situation. Latent Functions are those functions in which are the unknown

incorporating diagnosis groups as latent variables. First‚ we assume the patterns in a particular diagnosis group follow a multinomial distribution‚ which is a random variable draws from a prior Dirichlet distribution. By making analogies between words in documents and patterns of patients and inspiring from bag-of-words‚ we represent the observed patterns of a patient as a bag of patterns. Therefore‚ the generative process can be treated as the process of Latent Dirichlet Allocation (LDA)~\cite{blei2003LDA}

While it is easy to make comparisons between the pupil of the eye and the f-stop of a camera or between the retina of the eye and photographic film‚ once we get past the basic similarities of the optics of the two systems‚ comparisons begin to rapidly break down. The eye is not only much more complex than a camera and its film‚ but the two imaging devices function by different chemical mechanisms. The photographer (or the automatic exposure system of the camera) regulates the f-stop opening and time

Due to the stratification in the American social system and constant existence of the poor the government has set up certain welfare programs to help out the lower working class and poor. Among these programs‚ WIC was developed. WIC is a supplemental nutrition program that provides nutritious food‚ nutrition counseling‚ and referrals to health and other social services to participants at no charge. It is a federally funded program for which congress authorizes a specific amount

Engineering Materials Week 4 7.2 Consider two edge dislocations of opposite sign and having slip planes that are separated by several atomic distances. Briefly describe the defect that results when these two dislocations become aligned with each other. When the two edge dislocations become aligned‚ a planar region of vacancies will exist between the dislocations. 7.12 Consider a metal single crystal oriented such that normal to the slip plane and the slip direction are at angles 60 and 35 with the

Birth Defects A study funded by Monsanto to study possible birth defects caused by consuming aspartame was cut off after preliminary data showed damaging information about aspartame. Additionally‚ in the book‚ While Waiting: A Prenatal Guidebook‚ it is stated that aspartame is suspected of causing brain damage in sensitive individuals. A fetus may be at risk for these effects. Some researchers have suggested that high doses of aspartame may be associated with problems ranging from dizziness and

area Room Clean’. There are 14 specific days when the defects are particularly out of control. These days are highlighted in the attached analysis. With respect to the room clean defect only‚ there are 8 days out of control. Looking at room clean defects by day and total defects as a percent of occupancy indicates that weekends (especially) Sunday are the days most likely to result in a higher number of defects. The most significant defects on the out of control days are room clean and reservation
