Beef Producers\u27 Risk Perceptions of an Agroterrorism Event Occurring in Oklahoma
The purpose of this statewide study was to determine Oklahoma beef producers’ perceptions of the susceptibility of the state’s beef industry to a terrorist attack. Participants in this study were randomly selected from a population of 48,000 beef producers in this Oklahoma. All 470 respondents completed a telephone survey conducted by the Oklahoma Agricultural Statistics Service. Descriptive statistics, t-tests, and cross tabulations were used to analyze the data. Oklahoma beef producers perceived the beef industry was susceptible to an agroterrorism event, believed the feedlots to be at an elevated level of threat, were confident in their own operation’s biosecurity measures, believed their own operation was not susceptible to an agroterrorism event, and did not believe they had enough information about protection from terrorism to the beef industry
Before it Hits the Fan: Pre-Crisis Beef Producer Information Source Preferences
The purpose of this statewide study was to determine preferences for the sources of information beef producers in Oklahoma use and trust when they seek information about agriculture during a crisis. Participants in this study were randomly selected from a population of 48,000 beef producers in the Oklahoma. All 470 respondents completed a telephone survey conducted by the Oklahoma Agricultural Statistics Service (OASS). Descriptive statistics, t-tests, and cross tabulations were used to analyze the data. Producers preferred their veterinarians when seeking information about animal health issues and any agriculturally related crisis; and preferred to receive information through county extension publications. They also perceived the local veterinarian as the most trusted and reliable source of information available. The Oklahoma State University Cooperative Extension Service, through the county extension agents and the local area livestock specialists, and the USDA were also trustworthy and reliable sources
Agroterrorism and the Implications of Uncertainty Reduction Theory for Agricultural Communicators
As a consequence of various terrorist attacks on U.S. soil the vulnerability of American agriculture to an agro-terrorist attack has come into question. The objective of this paper is to view the threat of agroterrorism through the lens of uncertainty reduction theory and extend the original application of the theory from the realm of interpersonal communication to the mass communication level. We offer a brief overview of bioterrorism and agriculture and the general concepts of crisis communication and pre-crisis preparedness. We explain the relationship between the level of uncertainty and organizational crisis with the value of pre-crisis planning efforts. We show the importance of the agricultural communicator as a source of agricultural knowledge in the pre-crisis stage, which can contribute to reducing uncertainty following an agro-terrorist event
The Advanced Compton Telescope
The Advanced Compton Telescope (ACT), the next major step in gamma-ray astronomy, will probe the fires where chemical elements are formed by enabling high-resolution spectroscopy of nuclear emission from supernova explosions. During the past two years, our collaboration has been undertaking a NASA mission concept study for ACT. This study was designed to (1) transform the key scientific objectives into specific instrument requirements, (2) to identify the most promising technologies to meet those requirements, and (3) to design a viable mission concept for this instrument. We present the results of this study, including scientific goals and expected performance, mission design, and technology recommendations
Basking Shark (Cetorhinus maximus) Movements in the Eastern North Pacific Determined Using Satellite Telemetry
To fill data gaps on movements, behaviors and habitat use, both near- and offshore, two programs were initiated to deploy satellite tags on basking sharks off the coast of California. Basking sharks are large filter-feeding sharks that are second in size only to whale sharks. Similar to many megafauna populations, available data suggest that populations are below historic levels. In the eastern North Pacific (ENP) Ocean, the limited information on basking sharks comes from nearshore habitats where they forage. From 2010 to 2011, four sharks were tagged with pop-off satellite archival tags with deployments ranging from 9 to 240 days. The tags provided both transmitted and archived data on habitat use and geographic movement patterns. Nearshore, sharks tended to move north in the summer and prefer shelf and slope habitat around San Diego, Point Conception and Monterey Bay. The two sharks with 180 and 240 days deployments left the coast in the summer and fall. Offshore their paths diverged and by January one shark had moved to near the tip of the Baja Peninsula, Mexico and the other to the waters near Hawaii, USA. Vertical habitat use was variable both within and among individuals and changed as sharks moved offshore. Nearshore, most time was spent in the mixed layer but sharks did spend hours in cold waters below the mixed layer. Offshore vertical movements depended on location. The shark that went to Hawaii had a distinct diel pattern, with days spent at ~450–470 m and nights at ~250–300 m and almost no time in surface waters, corresponding with the diel migration of a specific portion of the deep scattering layer. The shark that moved south along the Baja Peninsula spent progressively more time in deep water but came to the surface daily. Movement patterns and shifts in vertical habitat and use are likely linked to shifts in prey availability and oceanography. Data collected indicate the potential for large-scale movements and the need for international dialogue in any recovery efforts

An Explanation of Negative Swap Spreads: Demand for Duration from Underfunded Pension Plans
Positive illusions and the happy mind
This chapter addresses the controversial question of whether happy minds gain happiness by cultivating positive illusions, that is, views of self that exaggerate one’s good qualities and degree of control over life and that involve unrealistically optimistic outlooks. Much evidence indicates that positive illusions contribute to well-being, but there are limits and contrary findings, and it is not viable to claim that engaging in endless rounds of self-flattering self-deception is a reliable guide to happiness. Illusions do confer benefits, including self-fulfilling prophecies and interpersonal appeal. We contrast two theories: a direct route by which self-deception makes one happy, and an indirect route by which positive illusions contribute to pragmatic, objective benefits, which in turn increase happiness. The evidence is mixed as to which route is more relevant. We note some negative effects of positive illusions, such as when they reduce effort and achievement
