Explain how you would design the study outlined below given the statements of purpose supplied. Be sure to include the population to be studied, the exclusion and inclusion criteria and data variables to be collected. ( Hint: you have already developed the research questions, use this to help design your study)Using data from the 1996 Medical Expenditure Panel Survey (MEPS), this study (1) examines the barriers to care faced by Hispanics, African Americans, Asian Americans, and non-Hispanic whites and whether barriers vary across these groups; (2) examines whether barriers to care vary between privately insured managed care and non–managed care enrollees within each of the four racial/ethnic groups; and (3) describes the socio-demographic, insurance, and health status characteristics of families that face barriers.

Problem 3: access control pokeygram, a cutting-edge new email start-up, is setting up building access for its employees. there are two types of employees: managers and engineers, and there are three departments: security, networking, and human resoures. each employee works in a single department, and each department is housed on a different floor. managers are allowed access to any floor, while engineers are allowed access only to their own floor. there are three badge-operated elevators, each going up to only one distinct floor. every employee has one badge. pokeygram wants to use the best possible access control method in order to minimize delay for the elevators (a) access control matrix, 1. which of the following would you recommend that pokeygram use: (b) access control lists, or (c) capabilities? make sure to justify your answer. 2. what, if any, would be the benefits (and/or disadvantages) of using rbac (role-based access control) in this situation? keep your solution for this problem limited to 10-12 lines of text.
