Research for efficiently planning and responding to natural disasters is of vital interest due to the devastating effects and losses caused by their occurrence, including economic deficiency, casualties, and infrastructure damage. Following the large breadth of natural disasters such as Hurricane Katrina in 2005, and the earthquake in Haiti in 2010, we observe a growing use of game theoretic models in the research concerning natural disaster management. In these models, government agencies and private companies interact as players in a disaster relief game. Notable research in these areas has studied multi-player games and multi-agency collaboration, among others, to provide insights into optimal decisions concerning defensive investment and private-public partnerships in the face of disaster occurrence. This paper aims to increase the comprehension of game theory-based research in disaster management and to provide directions for future research. We analyze and integrate 57 recent papers (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) to summarize game theory-based research in natural disaster and emergency management. We find that the response phase of disaster relief has been researched most extensively, and future research could be directed toward the other phases of disaster management such as mitigation, preparedness, and recovery. Attacker-defender games to be utilized relatively frequently to model both mitigation and response for a disaster. Defensive resource allocation and sequential/simultaneous games to model the interaction between agencies/individuals in light of a disaster are two other common ways to model disaster management. In addition to academia, the targeted audience of this research includes governments, private sectors, private citizens, and others who are concerned with or involved in disaster management.

The government, private sectors, and others users of the Internet are increasingly faced with the risk of cyber incidents. Damage to computer systems and theft of sensitive data caused by cyber attacks have the potential to result in lasting harm to entities under attack, or to society as a whole. The effects of cyber attacks are not always obvious, and detecting them is not a simple proposition. As the U.S. federal government believes that information sharing on cybersecurity issues among organizations is essential to safety, security, and resilience, the importance of trusted information exchange has been emphasized to support public and private decision making by encouraging the creation of the Information Sharing and Analysis Center (ISAC). Through a decision-theoretic approach, this article provides new perspectives on ISAC, and the advent of the new Information Sharing and Analysis Organizations (ISAOs), which are intended to provide similar benefits to organizations that cannot fit easily into the ISAC structure. To help understand the processes of information sharing against cyber threats, this article illustrates 15 representative information sharing structures between ISAC, government, and other participating entities, and provide discussions on the strategic interactions between different stakeholders. This article also identifies the costs of information sharing and information security borne by different parties in this public-private partnership both before and after cyber attacks, as well as the two main benefits. This article provides perspectives on the mechanism of information sharing and some detailed cost-benefit analysis.

The purpose of this study was to examine the validity of measures of temporal distance in a clinical analysis of gait. Data were collected from 15 normal subjects by one examiner. Equipment consisted of a 10-meter laminated walking track, dictaphone, metronome, and ink markers. The number of errors at four walking speeds were examined using a standardized analysis of gait. Analysis of variance showed a significant number of errors between the first and last halves of the measurement distance and among the four walking velocities. Post hoc analysis using the Scheffé test indicated significant differences in the mean number of errors at the velocities of 60 and 75 versus 25 and 40 m.min-1. An F test for simple effects indicated a significant number of errors occurred during the second half of the measured distance and at walking velocities of 60 and 75 m.min-1. These results indicate that the gait analysis is valid for measurements taken at all of the walking velocities only when recorded over a three-meter distance and only at the velocities of 25 and 40 m.min-1 over a six-meter distance.

The metro region of São Paulo, Brazil is home to over 21 million people, making it the eleventh most populous metro region in the world. High land costs and a lack of affordable housing leaves few options for low-income families, resulting in the illegal occupation of open land available in the periphery of the city. This land is often protected by environmental laws, thus putting both the occupation and the ecological balance at risk. Environmental advocates leverage Brazil's strict laws protecting the environment and employ narratives of environmental degradation to take legal action and evict occupants. On the other side, public defenders, human rights groups, and social movements fight for the residents' right to adequate housing. These seemingly opposing values are often played out at the expense of vulnerable communities who are often left homeless and resort to occupying other lands, continuing the cycle of conflict.
