Physical inactivity contributes to a growing proportion of illness and premature death in the United States. Only about 45 percent of Americans meet the recommended national standard for physical activity. Yet, analysis of 300 surveys collected from train riders at three walkable New Jersey suburban train stations showed that 78 percent met the activity guidelines. A new train station that allows these riders to save time in their commute has attracted new riders and has led existing commuters to change their commute. One-third of those surveyed reported additional physical activity primarily because they walked more after leaving the train in mid-town New York City. Only 8 percent reported less physical activity. The analysis revealed that the new public transit station and personal factors associated with a greater likelihood of using mass transit led to more physical activity.

This paper performs the utilization of cellular automata computational analysis as the dynamic model of spatial epidemiology. Here, explored elementary aspects of cellular automata and its application in analyzing contagious disease, in this case avian influenza disease in Indonesia. Computational model is built and map-based simulation is performed using several simplified data of such transportation through sea in Indonesia, and its accordance with poultries in Indonesia, with initial condition of notified avian influenza infected area in Indonesia. The initial places are Pekalongan, West Java, East Java, and several regions in Sumatera. The result of simulation is showing the spreading-rate of influenza and in simple way and describing possible preventive action through isolation of infected areas as a major step of preventing pandemic.

Consider a set of players who wish to randomly arrange themselves without a trusted third-party. For example, if there are 3 players, a, b and c, then a trusted third party could order them as abc, acb, bac, bca, cab, or cba. In the absence of a trusted third party, the players want to select one of these permutations for themselves at random. In this writing, a protocol (named “RandomSelect”) is presented using multiplayer computation. From a bag of all possible ways the players could be ordered, RandomSelect provides a means for players to make local choices that when combined, jointly select a permutation randomly. The RandomSelect protocol supports any number (n) of two or more players and computes properly even if n-1 players collude. Communication is O(n) using a broadcast channel. More generally, necessary and sufficient conditions for a class of functions called “RandomOrder ” functions are defined. A RandomOrder function uses n inputs to make a random selection of a string from a bag of n! strings where all possible selections are uniformly distributed over the possible inputs and over the strings. Any RandomOrder function can be used in the RandomSelect protocol. Bio-terrorism surveillance is used as an example application.

Water quality is a major environmental issue. Pollution from nonpoint sources is the single largest remaining source of water quality impairments in the United States. Agriculture is a major source of several nonpoint-source pollutants, including nutrients, sediment, pesticides, and salts. Agricultural nonpoint pollution reduction policies can be designed to induce producers to change their production practices in ways that improve the environmental and related economic consequences of production. The information necessary to design economically efficient pollution control policies is almost always lacking. Instead, policies can be designed to achieve specific environmental or other similarly-related goals at least cost, given transaction costs and any other political, legal, or informational constraints that may exist. This report outlines the economic characteristics of five instruments that can be used to reduce agricultural nonpoint source pollution (economic incentives, standards,...

Faith-based organizations (FBOs) are now being encouraged to seek federal funding for the purpose of supporting faith-based delivery of social services in local communities (i.e., Compassionate Capital Fund). In January 2001, the White House Office of Faith-Based and Community Initiatives was established by Executive Order along with Centers for Faith-Based

Objective: To estimate and describe the current prevalence of disability among Hawaii’s population. Design, Setting, and Participants: Random-digit telephone survey of 6,000 adults aged 18 and older residing in Hawaii and participating in the Behavioral Risk Factor Surveillance System in 2002 and the

We create an influence diagram of how a plague bioattack could unfold and then use it to identify factors shaping infection risks in many possible scenarios. The influence diagram and associated explanations provide a compact reference that allows risk communicators to identify key messages for pre-event preparation and testing. It can also be used to answer specific questions in whatever unique situations arise, considering both the conditions of the attack and the properties of the attacked populations. The influence diagram allows a quick, visual check of the factors that must be covered when evaluating audience information needs. The documentation provides content for explaining the resultant advice. We show how these tools can help in preparing for crises and responding to them. KEY WORDS: Bioterrorism; influence diagram; plague ecology; risk communication; rodents; Yersinia pestis
