Young men's use of aggressive tactics to avoid condom use: A test of a theoretical model.  

PubMed

Although research has demonstrated that men's aggression against women and inconsistent condom use are related phenomena, it is little is known as to what factors increase risk for aggression to avoid condom use. The present article tests a theory-based model of condom avoidance through sexual aggression. Adult male participants (N=289) were recruited nationally through online advertisements. Aggressive tactics to avoid condom use was measured using an adapted version of the revised Sexual Experiences Survey (Abbey et al., 2005) and assessed a variety of aggressive behaviors spanning coercion to physical force. 100 participants (35.3%) reported at least one instance of coercion or aggression to avoid using a condom. Structural equation modeling indicated that, attitudes towards women, inconsistent condom use, and number of sexual partners were significant predictors of aggressive tactics to avoid condom use. A better understanding of the attitudinal and behavioral pathways through which men avoid condom use through aggressive and coercive means will ultimately result in improved education and prevention efforts for at-risk men and women.

Mapping lessons from ants to free flight: an ant-based weather avoidance algorithm in free flight airspace  

NASA Astrophysics Data System (ADS)

The continuing growth of air traffic worldwide motivates the need for new approaches to air traffic management that are more flexible both in terms of traffic volume and weather. Free Flight is one such approach seriously considered by the aviation community. However the benefits of Free Flight are severely curtailed in the convective weather season when weather is highly active, leading aircrafts to deviate from their optimal trajectories. This paper investigates the use of ant colony optimization in generating optimal weather avoidance trajectories in Free Flight airspace. The problem is motivated by the need to take full advantage of the airspace capacity in a Free Flight environment, while maintaining safe separation between aircrafts and hazardous weather. The experiments described herein were run on a high fidelity Free Flight air traffic simulation system which allows for a variety of constraints on the computed routes and accurate measurement of environments dynamics. This permits us to estimate the desired behavior of an aircraft, including avoidance of changing hazardous weather patterns, turn and curvature constraints, and the horizontal separation standard and required time of arrival at a pre determined point, and to analyze the performance of our algorithm in various weather scenarios. The proposed Ant Colony Optimization based weather avoidance algorithm was able to find optimum weather free routes every time if they exist. In case of highly complex scenarios the algorithm comes out with the route which requires the aircraft to fly through the weather cells with least disturbances. All the solutions generated were within flight parameters and upon integration with the flight management system of the aircraft in a Free Flight air traffic simulator, successfully negotiated the bad weather.

Sun avoidance in the yellow baboons (Papio cynocephalus cynocephalus) of Ruaha National Park, Tanzania. Variations with season, behavior and weather  

NASA Astrophysics Data System (ADS)

Do free-ranging baboons avoid traveling towards the sun? Sun avoidance, in addition to resource and predator locations, may influence troop movement and non-random use of the home range. This paper investigates how sun avoidance, as measured by facial exposure to sunlight, influences directional choices. It hypothesizes that baboons should avoid the sun in the hot, dry season and show indifference to it in the cool, lush season. This paper also hypothesizes that baboons employ sun-avoidance behaviors more while they forage or travel to resting sites than when they travel to foraging sites or engage in active social behaviors; lastly this paper hypothesizes that sun altitude, temperature, humidity, and cloud cover influence sun-avoidance behavior. Using focal-animal techniques on 21 males from free-ranging baboon troops, I collected locational data, accurate to within 1.6 m, over 15 months. I calculated the difference between baboon bearings and the sun's azimuth in angular degrees. Both linear and circular statistics indicate that baboons put significantly (P<0.01) more than 90° between their bearing and the sun's azimuth under certain conditions. Contrary to hypotheses based on the detrimental effects of insolation, baboons in the cool, lush season avoid the sun, while baboons in the hot, dry season do not. In the lush season, the extent to which baboons avoid the sun does not depend on their other behaviors. Dry-season baboons demonstrate stronger sun avoidance while resting than when engaged in other behaviors. Finally, in the dry season, temperature drives sun avoidance; humidity drives it in the lush season.

Propagation effects in tactical radars  

NASA Astrophysics Data System (ADS)

Tactical battlefield radars are employed in surveillance and target acquisition roles at ranges of approximately 1 to 20 km, their main targets being enemy ground vehicles and personnel. As with all types of radar the operating environment has a significant effect on the design and performance of these systems and propagation considerations are an important factor. The major propagation factors which limit the performance of tactical radars are the availability of line of sight, ground clutter, and effects of the weather. The ways in which propagation factors affect the choice of such radar parameters as frequency, polarisation, and RF waveform are discussed, and the ways in which propagation constraints can be minimised by the design of the signal processing system are considered. In an EW environment an important operational requirement is to minimize the probability of the location of the position of the radar by the enemy. Propagation effects such as multipath and diffraction are considered in broad terms in this context.

The DLR Project - Weather & Flying  

NASA Astrophysics Data System (ADS)

A project is introduced which aims at (a) providing timely, tailored and concise meteorological information especially for adverse weather as precisely as possible for air traffic control and management, airline operating centres, pilots, and airports, and (b) building automated flight control systems and evasion-manoeuvre methods to minimise the impact of adverse wind and wake conditions on the flight performance of an aircraft. Today ATM and ATC most of the time only react on adverse weather when the disruption has already happened or is just about to happen. A future air traffic management should pro-actively anticipate disruptive weather elements and their time scales well in advance to avoid or to mitigate the impact upon the traffic flow. But "weather” is not a technical problem that can be simply solved. Predicting the weather is a difficult and complex task and only possible within certain limits. It is therefore necessary to observe and forecast the changing state of the atmosphere as precisely and as rapidly as possible. Measures must be taken to minimise the impact of adverse weather or changing weather conditions on air traffic management and tactical manoeuvring, both on ground and onboard the aircraft. Weather and meteorological information (MET in short) is to be considered as an integral part of air traffic management. In 2008, DLR has initiated a major project "Wetter & Fliegen” (German for "Weather and Flying”) to address this inter¬disciplinary challenge. Its goal is to augment safety and efficiency of air transportation, thereby focusing on the two German hub airports in Frankfurt and München. This high-level goal shall be reached by two strands of work: a) The development of an Integrated Terminal Weather Systems (ITWS) for the air¬¬ports at Frankfurt and München to improve the detection and forecast of weather phenomena adversely affecting airport operations, including deep convection (thunderstorms, hail, wind), wake vortex, and winter weather conditions, and b) The development of on-board systems for automated control, surveillance and information and the specification of requirements for on-board sensors, to improve the behaviour of the aircraft when confronted with wind gusts, wake vortices and thunderstorms. The project design and first results will be presented.

Tactical force protection  

NASA Astrophysics Data System (ADS)

The need for enhanced tactical force protection capabilities is evidenced from our recent experiences in Iraq and Afghanistan and occurs wherever U.S. Forces maintain a forward presence in a potentially hostile environment. Levels of force protection proficiency vary widely from combat units whose mission is to close with and destroy the enemy to combat support/combat service support units performing maintenance and logistics functions. We must provide force protection capabilities that are not only good enough to get the job done, but affordable for the entire force. Addressing the force protection challenge requires an investment in research and development to deliver affordable, scalable, modular and sustainable force protection equipment. This can be accomplished through an evolutionary acquisition strategy of capability upgrades in the near, mid and far-terms that leverage the Army's investments in unmanned ground sensors (UGS), unmanned ground vehicles (UGV) and surveillance radar and imaging technology. This approach addresses the field's immediate tactical force protection requirements, while working towards full integration with the Future Combat System. Futuristic Tactical Force Protection will consist of a fully integrated system of systems architecture that will include UGVs, UGS and Unmanned Aerial Vehicles (UAVs) that are networked with the Future Force.

Tactical reconnaissance mission survivability requirements  

NASA Astrophysics Data System (ADS)

Survivability has been a key operative word for the commanders of today's Air Force. Today's technology offers a substantial threat which challenges mission success, mission equipment, and platform survivability. In particular, the transition from photographic to electro-optical (E-O) tactical reconnaissance presents survivability issues that must be addressed today to properly plan and train for near-term deployment. In addition, the declining defense budget environment mandates that the USAF optimize its modern reconnaissance mission equipment to enhance tactical survivability. This paper discusses current, nonclassified, tactical reconnaissance mission tactics as taught at the Air National Guard Reconnaissance Weapons School. It examines the advantages and disadvantages of E-O technology in terms of mission, aircrew, and platform survivability and draws conclusions supporting the need for reconnaissance mission equipment which enhances survivability.

Tactical reconnaissance recorder alternatives  

NASA Astrophysics Data System (ADS)

The actual collection of data, such as digital imagery, using the multitude of sensors available today and in the near future, requires a high data rate digital recorder. The amount of memory, data rates, environmental factors and affordability are important issues when selecting the type of recording system. This paper will discuss two types of systems, tape and solid state. Emphasis will be placed on operational factors and specific mission profiles that are associated with a tactical reconnaissance mission. The current and projected costs of the digital tape recorder and soli state recorder will be examined. The logistics of moving the data from the aircraft to a Ground Exploitation System will be discussed. Once the data is collected it needs to be stored in non-volatile memory with easy access. One of the major problems encountered during Desert Storm was the inability to locate and retrieve reconnaissance images. A data base that can store terabytes of data and have the ability to recall this information from off-site locations should be a requirement for a Desert Storm scenario.

Tactical midinfrared testbed  

NASA Astrophysics Data System (ADS)

A new tactical airborne multicolor missile warning testbed was developed and fielded as part of an Air Force Research Laboratory (AFRL) initiative focusing on clutter and missile signature measurements for algorithm development. Multicolor discrimination is one of the most effective ways of improving the performance of infrared missile warning sensors, particularly for heavy clutter situations. Its utility has been demonstrated in fielded scanning sensors. Normally, multicolor discrimination is performed in the mid-infrared, 3-5 micrometers band, where the molecular emission of CO and CO2 characteristic of a combustion process is readily distinguished from the continuum of a black body radiator. Current infrared warning sensor development is focused on staring mosaic detector arrays that provide much higher frame rates than scanning systems in a more compact and mechanically simpler package. This, in turn, has required that multicolor clutter data be collected for both analysis and algorithm development. The developed sensor test bed is a 256x256 InSb sensor with an optimized two color filter wheel integrated with the optics. The collection portion includes a ruggedized parallel array processor and fast disk array capable of real-time processing and collection of up to 350 full frames per second. This configuration allowed the collection and real- time processing of temporally correlated, radiometrically calibrated data in two spectral bands that was compared to background and target imagery taken previously. The current data collections were taken from a modified Piper light aircraft at medium and low altitudes of background, battlefield clutter, and shoulder-fired missile signatures during August 1999.

Panoramic cockpit displays for tactical military cockpits  

NASA Astrophysics Data System (ADS)

The F-35 Joint Strike Fighter (JSF) incorporates the latest technology for aerial warfighting. To support this aircraft's mission and to provide the pilot with the increased situational awareness needed in today's battlespace, a panoramic AMLCD was developed and is being deployed for the first time. This 20" by 8" display is the largest fielded to date in a tactical fighter. Key system innovations had to be employed to allow this technology to function in this demanding environment. Certain older generation aircraft are now considering incorporating a panoramic display to provide their crews with this level of increased capability. Key design issues that had to be overcome dealt with sunlight readability, vibration resistance, touchscreen operation, and reliability concerns to avoid single-point failures. A completely dual redundant system design had to be employed to ensure that the pilot would always have access to critical mission and flight data.

Mechanical Weathering  

NSDL National Science Digital Library

This activity was designed to give students an opportunity to realize that all rocks weather mechanically and each specific rock type has its own particular rate of weathering. Students discover that mechanical weathering is the process of breaking down bedrock into smaller fragments by physical as opposed to chemical means and that rock weathering, although it seems to occur slowly in human terms, is an extremely significant part of the rock cycle. They will learn that weathered rock materials are called sediments and are the structural basis for soils and can also be compacted into sedimentary rock. Students will realize that rock weathering rates vary widely depending on mineral content, texture, rock type, and climate and that differential weathering (varying weathering rates for two or more rock types in physical contact with each other) has given rise to some of the world's most breathtaking scenery.

Digital HUDs for tactical aircraft  

NASA Astrophysics Data System (ADS)

For over four decades the Head Up Display (HUD) has been a critical instrument in tactical aircraft, as well as in an increasing number of commercial air transports. HUDs provide a unique means to present vital information to the pilot, precisely overlaid on the real world, without the need to look down or refocus onto the instrument panel displays. HUD imaging technology, using high brightness CRTs, has remained largely unchanged during this period, despite dramatic advances in display technology across the remainder of the avionics spectrum. As reliability improvements have reduced life cycle costs for other avionics systems, the relative cost of ownership for CRT-based HUDs has become increasingly unacceptable. Further, as special-purpose CRTs have steadily been replaced by digital display alternatives the number of potential sources has dwindled, raising growing parts obsolescence issues. These issues can be resolved by replacing the CRT and its associated electronics with a solid-state digital image engine. Such "digital" HUDs (DHUDs) have been certified for use in a number of commercial air transports, and are gaining wide acceptance in the user community. The operational and environmental requirements for DHUDs for tactical aircraft are more demanding than for transports, however the core technologies are in place to meet these needs. The stage is set to achieve excellent performance, dramatic life cycle cost reductions and low cost, for both legacy and new tactical aircraft. This paper describes digital HUD development efforts to date and summarizes key performance parameters and design issues.

Unaided tactical guidance flight test  

NASA Astrophysics Data System (ADS)

A low cost midcourse guidance technique suitable for standoff tactical weapons uses the launch aircraft navigation system and Kalman filtering to align and calibrate a weapon contained, low cost strapdown navigation system. Post launch, the strapdown system provides unaided inertial guidance along the midcourse trajectory. The strapdown sensor chosen to implement this form of guidance is the low cost inertial guidance subsystem (LCIGS), a modular strapdown package which uses embedded microprocessors, single degree of freedom gyroscopes, and pendulous mass accelerometers. Designed and built for use in tactical weapons, LCIGS features digital torque loops for the gyros and temperature compensation of all six sensors. Studies were conducted to project system performance, and the results indicate that through the alignment and calibration process the predominant LCIGS sensor errors can be reduced by an order of magnitude. A flight test program was structured to demonstrate performance. The unaided tactical guidance concept, the system hardware and software to be tested, the LCIGS and the preflight calibration features incorporated into its support equipment, unique laboratory testing to be performed on the system, and the planned flight tests are described.

Prognostic Analysis of the Tactical Quiet Generator  

SciTech Connect

The U.S. Army needs prognostic analysis of mission-critical equipment to enable condition-based maintenance before failure. ORNL has developed and patented prognostic technology that quantifies condition change from noisy, multi-channel, time-serial data. This report describes an initial application of ORNL's prognostic technology to the Army's Tactical Quiet Generator (TQG), which is designed to operate continuously at 10 kW. Less-than-full power operation causes unburned fuel to accumulate on internal components, thereby degrading operation and eventually leading to failure. The first objective of this work was identification of easily-acquired, process-indicative data. Two types of appropriate data were identified, namely output-electrical current and voltage, plus tri-axial acceleration (vibration). The second objective of this work was data quality analysis to avoid the garbage-in-garbage-out syndrome. Quality analysis identified more than 10% of the current data as having consecutive values that are constant, or that saturate at an extreme value. Consequently, the electrical data were not analyzed further. The third objective was condition-change analysis to indicate operational stress under non-ideal operation and machine degradation in proportion to the operational stress. Application of ORNL's novel phase-space dissimilarity measures to the vibration power quantified the rising operational stress in direct proportion to the less-than-full-load power. We conclude that ORNL's technology is an excellent candidate to meet the U.S. Army's need for equipment prognostication.

The effect of tranquilizers on the motivation components and tactics of operator's activities was investigated, using a model of discrete tracking of a moving object. The correlation-matrix method was applied to determine the region of no error correction. It was shown that specific changes in the tactics of operator's activities developing in response to tranquilizers and reduced motivation were identical. It appears probable that decreased motivation of failure avoidance forms the phenomenon of preparedness of risk taking and optimization of operator's activities when tranquilizers are used under psychological conflict conditions.

Space Weather  

NASA Astrophysics Data System (ADS)

Following James Van Allen's discovery of Earth's radiation belts (1958), it was immediately recognized that the space environment would be hostile to the communications satellites that had been envision by Arthur Clark (1945) and John Pierce (1955). Van Allen's discovery set off a burst of "space weather" research and engineering that continues to today, paralleling "space weather" research that had, prior to 1958, been directed toward understanding environment effects on cable and early wireless communications, electric power distribution, and pipelines. Van Allen's discovery also meant that the flight of humans above the sensible atmosphere would be fraught with more peril than mere weightlessness. This Van Allen lecture will discuss the space weather considerations that arose from Van Allen's discovery as well as space weather effects that occur from numerous other physical processes in the complex sun-heliosphere-magnetosphere environmental system.

General practitioners' strategies and tactics of communication with the terminally ill.  

PubMed

Interviews with 22 randomly selected general practitioners (GPs) investigated their communication with terminally ill patients. In interview analysis a conceptual distinction was drawn between objectives, strategies and tactics. When treating terminal patients, GPs expressed the objectives of keeping the patient comfortable, painfree, happy and maintaining dignity. A strategy is a plan and mode of approaching patients existing over an extended time period. Three strategies were described by GPs for use when interacting with terminally ill patients. These are characterized as 'try to disclose', 'let the patient decide' and 'avoid disclosing'. Tactics refer to behaviours used within a single consultation, as part of a strategy. Six tactics are described: evasion, denial, uncertainty, hints and prompts, euphemism and reassurance. Different strategies imply quite different forms of consultation. Thus to understand a consultation we must place it into the context of the series. PMID:7506681

Image fusion for tactical applications  

NASA Astrophysics Data System (ADS)

Multispectral sensors are increasingly being employed in military applications. Just as in satellite imagery of the earth, multispectral data is required in order to extract the maximum amount of information from a scene. The advantages of image fusion have been postulated for navigation, surveillance, fire control, and missile guidance to improve accuracy and contribute to mission success. The fusion process is a critical element of each of these applications. Imagery from various sensors must be calibrated, enhanced and spatially registered in order to achieve the desired 'fusion' of information into a single 'picture' for rapid assessment. In a tactical military environment this fusion of data must be presented to the end user in a timely and ergonomical fashion. The end user (e.g., a combat pilot) may already be operating at maximum sensory input capacity. Does he or she really need another cockpit display?

We identify tactical voting as the driving ingredient for the anomalies and introduce a model to study its effect on plurality elections, characterized by the relative strength of the feedback from polls and the pairwise interaction between individuals in the society. With this model it becomes possible to explain the polarization of votes between two candidates, understand the small margin of victories frequently observed for different elections, and analyze the polls' impact in American, Canadian, and Brazilian ballots. Moreover, the model reproduces, quantitatively, the distribution of votes obtained in the Brazilian mayor elections with two, three, and four candidates. PMID:20856800

Space Weather  

NASA Astrophysics Data System (ADS)

This volume provides a comprehensive overview of our current observational knowledge, theoretical understanding, and numerical capability with regard to the phenomena known as space weather. Space weather refers to conditions on the Sun and in the solar wind, magnetosphere, ionosphere, and thermosphere that can influence the performance and reliability of space-borne and ground-based technological systems, and can endanger human life or health. The rapid advance in these technologies has provided us with unprecedented capability and convenience, and we have come to rely on them more and more. Technology has reduced society's risk to many kinds of natural disasters, but through its own vulnerability, it has actually increased society's risk to space weather. Adverse conditions in the space environment can cause disruption of satellite operations, communications, navigation, and electric power distribution grids, leading to a variety of socioeconomic losses.

Trauma ultrasound in civilian tactical medicine.

The term "tactical medicine" can be defined in more than one way, but in the nonmilitary setting the term tactical emergency medical services (TEMS) is often used to denote medical support operations for law enforcement. In supporting operations involving groups such as special weapons and tactics (SWAT) teams, TEMS entail executing triage, diagnosis, stabilization, and evacuation decision-making in challenging settings. Ultrasound, now well entrenched as a part of trauma evaluation in the hospital setting, has been investigated in the prehospital arena and may have utility in TEMS. This paper addresses potential use of US in the tactical environment, with emphasis on the lessons of recent years' literature. Possible uses of US are discussed, in terms of both specific clinical applications and also with respect to informing triage and related decision making. PMID:23243509

Weather Watchers  

NSDL National Science Digital Library

Students are introduced to some essential meteorology concepts so they more fully understand the impact of meteorological activity on air pollution control and prevention. First, they develop an understanding of the magnitude and importance of air pressure. Next, they build a simple aneroid barometer to understand how air pressure information is related to weather prediction. Then, students explore the concept of relative humidity and its connection to weather prediction. Finally, students learn about air convection currents and temperature inversions. In an associated literacy activity, students learn how scientific terms are formed using Latin and Greek roots, prefixes and suffixes, and are introduced to the role played by metaphor in language development. Note: Some of these activities can be conducted simultaneously with the air quality activity (What Color Is Your Air Today?) of Air Pollution unit, Lesson 1.

Distributed tactical reasoning framework for intelligent vehicles  

NASA Astrophysics Data System (ADS)

In independent vehicle concepts for the Automated Highway System (AHS), the ability to make competent tactical-level decisions in real-time is crucial. Traditional approaches to tactical reasoning typically involve the implementation of large monolithic systems, such as decision trees or finite state machines. However, as the complexity of the environment grows, the unforeseen interactions between components can make modifications to such systems very challenging. For example, changing an overtaking behavior may require several, non-local changes to car-following, lane changing and gap acceptance rules. This paper presents a distributed solution to the problem. PolySAPIENT consists of a collection of autonomous modules, each specializing in a particular aspect of the driving task - classified by traffic entities rather than tactical behavior. Thus, the influence of the vehicle ahead on the available actions is managed by one reasoning object, while the implications of an approaching exit are managed by another. The independent recommendations form these reasoning objects are expressed in the form of votes and vetos over a 'tactical action space', and are resolved by a voting arbiter. This local independence enables PolySAPIENT reasoning objects to be developed independently, using a heterogenous implementation. PolySAPIENT vehicles are implemented in the SHIVA tactical highway simulator, whose vehicles are based on the Carnegie Mellon Navlab robots.

Weather data gap problem resolved

It looks as though the United States will avoid the crisis situation of a gap in weather data resulting from the aging GOES-7 satellite and technical problems with the next generation of weather satellites (GOESNEXT). Officials at the National Oceanic and Atmospheric Administration, which oversees the National Weather Service, recently announced their decision to borrow at least one and possibly several European satellites until the GOES-NEXT program gets off the ground.The GOES (Geostationary Operational Environmental Satellites) series is currently 3 years behind schedule and $500 million over budget. Problems with its complex design, program management by both NOAA and the National Aeronautics and Space Administration and poor performance by the contractor led Department of Commerce Secretary Robert Mosbacher to slow down the GOES-NEXT series to ensure that it is built right.

Cooperation creates selection for tactical deception  

PubMed Central

Conditional social behaviours such as partner choice and reciprocity are held to be key mechanisms facilitating the evolution of cooperation, particularly in humans. Although how these mechanisms select for cooperation has been explored extensively, their potential to select simultaneously for complex cheating strategies has been largely overlooked. Tactical deception, the misrepresentation of the state of the world to another individual, may allow cheaters to exploit conditional cooperation by tactically misrepresenting their past actions and/or current intentions. Here we first use a simple game-theoretic model to show that the evolution of cooperation can create selection pressures favouring the evolution of tactical deception. This effect is driven by deception weakening cheater detection in conditional cooperators, allowing tactical deceivers to elicit cooperation at lower costs, while simple cheats are recognized and discriminated against. We then provide support for our theoretical predictions using a comparative analysis of deception across primate species. Our results suggest that the evolution of conditional strategies may, in addition to promoting cooperation, select for astute cheating and associated psychological abilities. Ultimately, our ability to convincingly lie to each other may have evolved as a direct result of our cooperative nature.

This field-based study analyzed effects of a deliberate-play training program in basketball on tactical game intelligence and tactical creativity. 22 youth basketball players, ages 10 to 12 years, completed basketball training in one of two equal-sized groups. The deliberate-play training program contained unstructured game forms in basketball. The placebo group played in traditional structured basketball game forms. Tactical intelligence and creativity was assessed before and after an 18-lesson intervention. Analysis showed significant training improvement only for the deliberate-play group. In addition, this outperformance of the placebo group was not only observed for tactical creativity but also for tactical intelligence. PMID:20681337

It pays to cheat: tactical deception in a cephalopod social signalling system  

PubMed Central

Signals in intraspecific communication should be inherently honest; otherwise the system is prone to collapse. Theory predicts, however, that honest signalling systems are susceptible to invasion by cheats, the extent of which is largely mediated by fear of reprisal. Cuttlefish facultatively change their shape and colour, an ability that evolved to avoid predators and capture prey. Here, we show that this ability is tactically employed by male mourning cuttlefish (Sepia plangon) to mislead conspecifics during courtship in a specific social context amenable to cheating 39 per cent of the time, while it was never employed in other social contexts. Males deceive rival males by displaying male courtship patterns to receptive females on one side of the body, and simultaneously displaying female patterns to a single rival male on the other, thus preventing the rival from disrupting courtship. The use of tactical deception in such a complex communication network indicates that sociality has played a key role in the cognitive evolution of cephalopods.

Genetically modified plants for tactical systems applications  

NASA Astrophysics Data System (ADS)

Plants are ubiquitous in the environment and have the ability to respond to their environment physiologically and through altered gene expression profiles (they cannot walk away). In addition, plant genetic transformation techniques and genomic information in plants are becoming increasingly advanced. We have been performing research to express the jellyfish green fluorescent protein (GFP) in plants. GFP emits green light when excited by blue or UV light. In addition, my group and collaborators have developed methods to detect GFP in plants by contact instruments and at a standoff. There are several tactical uses for this technology. Some obvious applications are using plants as sentinels for detecting biological and chemical warfare agents or their derivatives from a remote platform, as well as detecting explosives. Another tactical application is covert monitoring using individual plants. Different methods to detect GFP in transgenic plants will be discussed.

Operational space support to tactical forces  

NASA Astrophysics Data System (ADS)

The use of military spacecraft for supporting strategic forces is discussed emphasizing the requirements of ground mobile forces and the availability of space-based resources. Specific attention is given to the incompatibility of the Milsatcom communications network and military needs for combat situations. The need for assured access to tactical communications free of electronic jammers is identified, and the characteristics of tactical user equipment are set forth. The idea of a 'Space Hummer' is proposed which receives and processes multifrequency data in a high-mobility multipurpose wheeled vehicle. The proposed vehicle is described in terms of existing and deficient technologies required for its implementation, and scenarios for its use in covert and other operations are reviewed. Important technological challenges for the use of space support include reduced antenna sizes, data fusion, and wideband connectivity, and some of these areas are currently being investigated.

From the laboratory to the soldier: providing tactical behaviors for Army robots  

NASA Astrophysics Data System (ADS)

The Army Future Combat System (FCS) Operational Requirement Document has identified a number of advanced robot tactical behavior requirements to enable the Future Brigade Combat Team (FBCT). The FBCT advanced tactical behaviors include Sentinel Behavior, Obstacle Avoidance Behavior, and Scaled Levels of Human-Machine control Behavior. The U.S. Army Training and Doctrine Command, (TRADOC) Maneuver Support Center (MANSCEN) has also documented a number of robotic behavior requirements for the Army non FCS forces such as the Infantry Brigade Combat Team (IBCT), Stryker Brigade Combat Team (SBCT), and Heavy Brigade Combat Team (HBCT). The general categories of useful robot tactical behaviors include Ground/Air Mobility behaviors, Tactical Mission behaviors, Manned-Unmanned Teaming behaviors, and Soldier-Robot Interface behaviors. Many DoD research and development centers are achieving the necessary components necessary for artificial tactical behaviors for ground and air robots to include the Army Research Laboratory (ARL), U.S. Army Research, Development and Engineering Command (RDECOM), Space and Naval Warfare (SPAWAR) Systems Center, US Army Tank-Automotive Research, Development and Engineering Center (TARDEC) and non DoD labs such as Department of Energy (DOL). With the support of the Joint Ground Robotics Enterprise (JGRE) through DoD and non DoD labs the Army Maneuver Support Center has recently concluded successful field trails of ground and air robots with specialized tactical behaviors and sensors to enable semi autonomous detection, reporting, and marking of explosive hazards to include Improvised Explosive Devices (IED) and landmines. A specific goal of this effort was to assess how collaborative behaviors for multiple unmanned air and ground vehicles can reduce risks to Soldiers and increase efficiency for on and off route explosive hazard detection, reporting, and marking. This paper discusses experimental results achieved with a robotic countermine system that utilizes autonomous behaviors and a mixed-initiative control scheme to address the challenges of detecting and marking buried landmines. Emerging requirements for robotic countermine operations are outlined as are the technologies developed under this effort to address them. A first experiment shows that the resulting system was able to find and mark landmines with a very low level of human involvement. In addition, the data indicates that the robotic system is able to decrease the time to find mines and increase the detection accuracy and reliability. Finally, the paper presents current efforts to incorporate new countermine sensors and port the resulting behaviors to two fielded military systems for rigorous assessing.

Interviews with 30 Nordic expatriates reveal that divergent communication styles, the cultural values of verticality and collectivism, and the lack of shared language have a negative impact on intercultural communication. The interviews reveal that rather than remaining passive bystanders, expatriates adopt various tactics to increase

Time for Europeans to Debate the Presence of Tactical Nukes  

ERIC Educational Resources Information Center

|The superpowers are making decisions about tactical and nuclear weapons which may be immutable for Europe for the next 20 years. The maintenance of arsenals for tactical and nuclear weapons should be discussed by more than just the closed circle of professional strategists-by journalists, politicians, philosophers and thoughtful citizens.

Evolving coordinated spatial tactics for autonomous entities using influence maps  

Microsoft Academic Search

We evolve tactical control for entity groups in a naval real-time strategy game. Since tactical maneuvering involves spatial reasoning, our evolutionary algorithm evolves a set of influence maps that help specify an entity's spatial objectives. The entity then uses the A* route finding algorithm to generate waypoints according to the influence map, and follows them to achieve spatial objectives. Using

Heuristic automation for decluttering tactical displays.  

PubMed

Tactical displays can quickly become cluttered with large numbers of symbols that can compromise effective monitoring. Here, we studied how heuristic automation can aid users by intelligently "decluttering" the display. In a realistic simulated naval air defense task, 27 experienced U.S. Navy users monitored a cluttered airspace and executed defensive responses against significant threats. An algorithm continuously evaluated aircraft for their levels of threat and decluttered the less threatening ones by dimming their symbols. Users appropriately distrusted and spot-checked the automation's assessments, and decluttering had very little effect on which aircraft were judged as significantly threatening. Nonetheless, decluttering improved the timeliness of responses to threatening aircraft by 25% as compared with a baseline display with no decluttering; it was especially beneficial for threats in more peripheral locations, and 25 of 27 participants preferred decluttering. Heuristic automation, when properly designed to guide users' attention by decluttering less important objects, may prove valuable in many cluttered monitoring situations, including air traffic management, crisis team management, and tactical situation awareness in general.

Tacticity effects on viscoelastic properties of polystyrenes  

NASA Astrophysics Data System (ADS)

Polystyrenes (PS) with a similar molecular weight and distribution but different tacticities, i. e. syndiotactic (s-PS), atactic (a-PS), and isotactic (i-PS), have been used in this study for a fair comparison to reveal their differences in the viscoelastic properties. Our attention was focused on the influence of the PS tacticity on the rheological properties, especially the plateau shear modulus GN^0 and entanglement molecular weight Me. Based on the time-temperature superposition principle, the master curves of dynamic storage modulus G'(?), dynamic loss modulus G?(?), and tan? at a reference temperature of 280^oC were constructed. The feasibility of conventional approaches for determining GN^0 , i. e. minimum tan?criterion, the integration method, and an empirical equation derived by Wu, has been discussed and compared; the corresponding Me is then derived by the classical relation: Me=?RT/GN^o . Our results show that the measured Me and activation energy for flow are similar for s-PS and a-PS, but the highest for i-PS. In addition, the zero shear viscosity of i-PS is ca. one order larger than that of s-PS and a-PS.

Diagnosing degradation of services in hybrid wireless tactical networks  

NASA Astrophysics Data System (ADS)

In this paper, we consider a problem related to service management and deployment in tactical military networks. Tactical networks are typically hybrid wireless networks in which there are both static and mobile nodes with several wireless interfaces, such as 802.11, 3G, satellite, etc. In tactical networks, performance degradation in services could prove fatal, so it must be diagnosed quickly. This degradation could be due to mobility or bottlenecks in capacity at network layer. We provide a cross-layer framework to detect and diagnose these causes of performance degradation as part of service management; it includes a monitoring model of services and a network model for hybrid wireless networks. In addition, we give a working example in tactical military networks to illustrate our framework. We provide an experimental setup to simulate our hybrid wireless tactical network scenario along with preliminary results.

Socialization tactics, employee proactivity, and person-organization fit.

This study examined the linkage between organizational socialization tactics and person-organization (P-O) fit and examined the moderating influence of employees' proactivity behaviors. Results from a sample of 279 employee-supervisor pairs from 7 organizations in South Korea revealed a positive relationship between institutionalized socialization tactics and P-O fit perceptions. However, the association between firms' socialization tactics and P-O fit was facilitated or negated by several proactive behaviors that employees used to gain control over their environment. For example, employees' positive framing harmonized with institutional tactics to create higher P-O fit, whereas employees who proactively developed strong relationships with their supervisors essentially replaced institutionalized socialization tactics.

A survey of customers of space weather information  

NASA Astrophysics Data System (ADS)

We present an analysis of the users of space weather information based on 2783 responses to an online survey among subscribers of NOAA's Space Weather Prediction Center e-mail services. The survey requested information focused on the three NOAA space weather scales: geomagnetic storms, solar radiation storms, and radio blackouts. Space weather information is most commonly obtained for reasons of human safety and continuity or reliability of operations. The information is primarily used for situational awareness, as aid to understand anomalies, to avoid impacts on current and near-future operations by implementing mitigating strategies, and to prepare for potential near-future impacts that might occur in conjunction with contingencies that include electric power outages or GPS perturbations. Interest in, anticipated impacts from, and responses to the three main categories of space weather are quite uniform across societal sectors. Approximately 40% of the respondents expect serious to very serious impacts from space weather events if no action were taken to mitigate or in the absence of adequate space weather information. The impacts of space weather are deemed to be substantially reduced because of the availability of, and their response to, space weather forecasts and alerts. Current and near-future space weather conditions are generally highly valued, considered useful, and generally, though not fully, adequate to avoid or mitigate societal impacts. We conclude that even among those receiving space weather information, there is considerable uncertainty about the possible impacts of space weather and thus about how to act on the space weather information that is provided.

Avalanche Weather Forecasting  

NSDL National Science Digital Library

Avalanches form through the interaction of snowpack, terrain, and weather, the latter being the focus of this module. The module begins with basic information about avalanches, highlighting weather's role in their development. The rest of the module teaches weather forecasters how to make an avalanche weather forecast, that is, one in which key weather parameters are evaluated for their impact on avalanche potential. The forecasts are used primarily by avalanche forecasters, who integrate them with other information to determine when to issue avalanche hazard warnings. The module contains five cases that let users apply the avalanche weather forecast process to different combinations of snowpack, terrain, and weather conditions. It is a companion to the COMET module "Snowpack and Its Assessment," which describes snowpack development and various assessment techniques.

Weather and emotional state  

NASA Astrophysics Data System (ADS)

Introduction Given the proven effects of weather on the human organism, an attempt to examine its effects on a psychic and emotional level has been made. Emotions affect the bio-tonus, working ability and concentration, hence their significance in various domains of economic life, such as health care, education, transportation, tourism, etc. Data and methods The research has been made in Sofia City within a period of 8 months, using 5 psychological methods (Eysenck Personality Questionnaire (EPQ), State-Trait Anxiety Inventory (STAI), Test for Self-assessment of the emotional state (developed by Wessman and Ricks), Test for evaluation of moods and Test "Self-confidence - Activity - Mood" (developed by the specialists from the Military Academy in Saint Petersburg). The Fiodorov-Chubukov's complex-climatic method was used to characterize meteorological conditions because of the purpose to include in the analysis a maximal number of meteorological elements. 16 weather types are defined in dependence of the meteorological elements values according to this method. Abrupt weather changes from one day to another, defined by the same method, were considered as well. Results and discussions The results obtained by t-test show that the different categories of weather lead to changes in the emotional status, which indicates a character either positive or negative for the organism. The abrupt weather changes, according to expectations, have negative effect on human emotions but only when a transition to the cloudy weather or weather type, classified as "unfavourable" has been realized. The relationship between weather and human emotions is rather complicated since it depends on individual characteristics of people. One of these individual psychological characteristics, marked by the dimension "neuroticism", has a strong effect on emotional reactions in different weather conditions. Emotionally stable individuals are more "protected" to the weather influence on their emotions, while those who are emotionally unstable have a stronger dependence to the impacts of the weather.

The mate choices of children do not always meet with the approval of their parents. As a consequence, the latter employ a battery of tactics that they use to manipulate the mating behavior of the former. This paper offers the first taxonomy of parental tactics of mate choice manipulation. In particular, in Study 1, 57 semi-structured interviews revealed 72 acts that parents employ to influence their children, and 27 that they employ to influence their children's partners. In Study 2, 405 parents rated how likely they were to use these acts to influence their daughters' and sons' mate choices. Factor analysis of participants' responses revealed 12 manipulation tactics that parents use on their children, and four manipulation tactics that they use on their children's partners.

Supporting tactical intelligence using collaborative environments and social networking  

NASA Astrophysics Data System (ADS)

Modern military environments place an increased emphasis on the collection and analysis of intelligence at the tactical level. The deployment of analytical tools at the tactical level helps support the Warfighter's need for rapid collection, analysis, and dissemination of intelligence. However, given the lack of experience and staffing at the tactical level, most of the available intelligence is not exploited. Tactical environments are staffed by a new generation of intelligence analysts who are well-versed in modern collaboration environments and social networking. An opportunity exists to enhance tactical intelligence analysis by exploiting these personnel strengths, but is dependent on appropriately designed information sharing technologies. Existing social information sharing technologies enable users to publish information quickly, but do not unite or organize information in a manner that effectively supports intelligence analysis. In this paper, we present an alternative approach to structuring and supporting tactical intelligence analysis that combines the benefits of existing concepts, and provide detail on a prototype system embodying that approach. Since this approach employs familiar collaboration support concepts from social media, it enables new-generation analysts to identify the decision-relevant data scattered among databases and the mental models of other personnel, increasing the timeliness of collaborative analysis. Also, the approach enables analysts to collaborate visually to associate heterogeneous and uncertain data within the intelligence analysis process, increasing the robustness of collaborative analyses. Utilizing this familiar dynamic collaboration environment, we hope to achieve a significant reduction of time and skill required to glean actionable intelligence in these challenging operational environments.

Fair weather atmospheric electricity  

NASA Astrophysics Data System (ADS)

Not long after Franklin's iconic studies, an atmospheric electric field was discovered in "fair weather" regions, well away from thunderstorms. The origin of the fair weather field was sought by Lord Kelvin, through development of electrostatic instrumentation and early data logging techniques, but was ultimately explained through the global circuit model of C.T.R. Wilson. In Wilson's model, charge exchanged by disturbed weather electrifies the ionosphere, and returns via a small vertical current density in fair weather regions. New insights into the relevance of fair weather atmospheric electricity to terrestrial and planetary atmospheres are now emerging. For example, there is a possible role of the global circuit current density in atmospheric processes, such as cloud formation. Beyond natural atmospheric processes, a novel practical application is the use of early atmospheric electrostatic investigations to provide quantitative information on past urban air pollution.

Space Weather Applications and Spacecraft Anomalies  

NASA Astrophysics Data System (ADS)

The first priority for the use of space weather information for improving spacecraft performance is in the diagnosis of anomalies so that designs and procedures may be optimised to limit their occurrence. The association of certain spacecraft anomalies with the space environment is well established on the basis of statistical correlations with space weather indicators. However, the global indicators commonly used are frequently only an indirect measure of the aspects of the environment that causes the anomaly. Better diagnosis of anomalies should be possible by processing raw data to extract physically relevant parameters. Spacecraft operators can rapidly diagnose anomalies and even anticipate or avoid them if provided with now-casts and short-term forecasts of relevant hazard indicators. This is the goal of space weather applications like GEOSHAFT, part of ESA's network of space weather prototype services. The space weather indices currently available need to be supplemented by data that is more directly related to the way the space environment interacts with electronic equipment, e.g. for the outer belt, charging current is preferred to electron flux; and for solar particle events LET is preferred to energy. Instruments such as Merlin are focussed on collecting data which will aid anomaly diagnosis.

Self-reported tactics of impulse control.  

PubMed

Recent behavioral research has suggested that delayed incentives are discounted in a highly concave curve, which should produce temporary preference for the poorer of two alternatives when that alternative is available earlier than the better one. Unlike the psychoanalytic model of impulsiveness, the temporary preference model implies a rational need for people to forestall impulses by committing their choices in advance. A questionnaire elicited college students' and prisoners' self-reports of approval of four basic kinds of precommitting tactics as applied to 14 commonplace temptations. Endorsement of private rules as a precommitting device was correlated with self-reported compulsive personality traits and negatively correlated with endorsement of extra-psychic (social or physical) devices; the latter endorsement was correlated with self-reported oral/paranoid traits. Female subjects endorsed attention control as a precommitting device more than males, and male subjects endorsed extrapsychic devices more than females. The ego psychology of conflict may be practical at the conscious level. PMID:3570571

Design tradeoff considerations for tactical cryocoolers  

NASA Astrophysics Data System (ADS)

The trade-offs that must be considered when selecting a cryocooler for infrared detector cooling are complex. When split- Stirling cryocoolers are used, the designer can select the expander separately from the compressor. However, there will be performance implications. Larger systems provide benefits in terms of performance margin and operating lifetime, but may not meet size and mass goals. Larger cryocoolers tend to generate more heat, albeit over a larger surface area, and generate higher vibration forces. The expander coldfinger must be stiff enough to achieve image plane motion requirements. The transfer tube should be as short and with as few bends as possible, while the path available for the transfer tube may be affected by the geometry of the expander and compressor. Several characteristics of tactical cryocoolers are considered in this paper in such a way that trends can be identified and design choices can be clarified. A step-by-step approach is recommended that will lead to a design solution in the most direct manner. This is accomplished by starting with "show-stopper" choices, then progressing to choices where concessions can be more easily made. The implications of the interfaces to the cryocooler will also be briefly discussed. Cryocooler developments at RVS that will expand the available design space are described. This enabling technology provides more options in terms of cryocooler size and performance, and continues the trend toward longer operating lifetime and higher reliability.

Satellite system for tactical MILSATCOM applications  

NASA Astrophysics Data System (ADS)

The communication requirements for continuous MILSATCOM service can be met by augmenting the current and planned MILSATCOM systems with a functionally simple, low-cost, maneuverable, user-dedicated satellite constellation for tactical applications (TACSAT) whose payloads are under direct control of the theater Commander in Chief (CINC). A perspective on moderately hardened, low-cost SHF and EHF satellites that have minimal impact on the ground infrastructure to satisfy such missions is presented. The communication and coverage requirements of the theater CINCs are discussed, followed by an SHF versus EHF comparison. Four different SHF payloads (including an enhanced DSCS replenishment) and two EHF payloads are evaluated. The spacecraft systems to integrate these payload options, including the spacecraft, launch vehicles, and ground segment, are addressed. Parametric trade studies of communication capacity and satellite life/maneuverability are presented. Ground segment operational scenarios based on a computer simulation of ground mobile forces (GMF) network for a given connectivity are presented. The various architectures proposed are analyzed and compared by generating a figure-of-merit unit per 1 MHz transponder capacity for each option.

Quality of service for tactical wireless networks  

NASA Astrophysics Data System (ADS)

Applications resident on tactical wireless networks are levying increasing offered loads. Tradeoffs can be made between range and throughput, but the wireless network is destined to be considered a limitation in information transfer. If managed correctly, the network can be an intelligent aid in ensuring the right information gets to the right place at the right time. Over the last 5 years, SAIC has worked with Natick Soldier Center (NSRDEC) to provide reliable communication with guaranteed service quality for the dismounted soldier. The effort utilizes a series of tools to mark, shape, condense, fragment and persist information for congestion and corruption control. The critical aspect of the congestion control solution is accomplished by adaptively throttling lower priority information at the sending node before it gets pushed to the wireless realm. Of note is that the solution adapts through passive processes without control messages. The solution also implements compression of messages and images, along with fragmentation techniques to alleviate congestion. Information corruption is purely a radio phenomenon and cannot be overcome through cognitive solutions. However, the solution mitigates corruption through information persistence and reliable retransmission. The implemented solution, unlike Transport Control Protocol, is optimized for wireless networks and demonstrates reduction of added signaling traffic. Combined congestion and corruption techniques have demonstrated how soldiers can get the right information at the right time during high traffic loads or network segmentation.

The Space Weather Reanalysis  

NASA Astrophysics Data System (ADS)

The objective of this project is to generate a complete 11 year space weather representation using physically consistent data-driven space weather models. The project will create a consistent, integrated historical record of the near Earth space environment by coupling observational data from space environmental monitoring systems archived at NGDC with data-driven, physically based numerical models. The resulting product will be an enhanced look at the space environment on consistent grids, time resolution, coordinate systems and containing key fields allowing an interested user to quickly and easily incorporate the impact of the near-Earth space climate in environmentally sensitive models. Currently there are no easily accessible long term climate archives available for the space-weather environment. Just as with terrestrial weather it is crucial to understand both daily weather forecasts as well as long term climate changes, so this project will demonstrate the ability to generate a meaningful and physically derived space weather climatology. The results of this project strongly support the DOD's Environmental Scenario Generator (ESG) project. The ESG project provides tools for intellegent data mining, classification and event detection which could be applied to a historical space-weather database. The two projects together provide a suite of tools for the user interested in modeling the effect of the near-earth space environment. We will present results and methodologies developed during the first two years of effort in the project.

It pays to cheat: tactical deception in a cephalopod social signalling system.  

PubMed

Signals in intraspecific communication should be inherently honest; otherwise the system is prone to collapse. Theory predicts, however, that honest signalling systems are susceptible to invasion by cheats, the extent of which is largely mediated by fear of reprisal. Cuttlefish facultatively change their shape and colour, an ability that evolved to avoid predators and capture prey. Here, we show that this ability is tactically employed by male mourning cuttlefish (Sepia plangon) to mislead conspecifics during courtship in a specific social context amenable to cheating 39 per cent of the time, while it was never employed in other social contexts. Males deceive rival males by displaying male courtship patterns to receptive females on one side of the body, and simultaneously displaying female patterns to a single rival male on the other, thus preventing the rival from disrupting courtship. The use of tactical deception in such a complex communication network indicates that sociality has played a key role in the cognitive evolution of cephalopods. PMID:22764112

Comparative phylogenetic analysis of male alternative reproductive tactics in ray-finned fishes.  

PubMed

Using comparative phylogenetic analysis, we analyzed the evolution of male alternative reproductive tactics (MARTs) in ray-finned fishes (Actinopterygii). Numerous independent origins for each type of MART (involving sneaker males, female mimics, pirates, and satellite males) indicate that these behaviors have been highly labile across actinopterygiian evolution, consistent with a previous notion that convergent selection in fishes can readily mold the underlying suites of reproductive hormones into similar behaviors. The evolutionary appearance of MARTs was significantly correlated with the presence of sexually selected traits in bourgeois males (P = 0.001) but not with the presence of male parental care. This suggests that MARTs often arise from selection on some males to circumvent bourgeois male investment in mate monopolization, rather than to avoid male brood care per se. We found parsimony evidence for an evolutionary progression of MARTs wherein sneaking is usually the evolutionary precursor to the presumably more complex MARTs of female mimicry and cooperative satellite behavior. Nest piracy appears not to be part of this evolutionary progression, possibly because its late onset in the life cycle of most ray-finned fishes reduces the effects of selection on this reproductive tactic.

Cooperative organic mine avoidance path planning  

NASA Astrophysics Data System (ADS)

The JHU/APL Path Planning team has developed path planning techniques to look for paths that balance the utility and risk associated with different routes through a minefield. Extending on previous years' efforts, we investigated real-world Naval mine avoidance requirements and developed a tactical decision aid (TDA) that satisfies those requirements. APL has developed new mine path planning techniques using graph based and genetic algorithms which quickly produce near-minimum risk paths for complicated fitness functions incorporating risk, path length, ship kinematics, and naval doctrine. The TDA user interface, a Java Swing application that obtains data via Corba interfaces to path planning databases, allows the operator to explore a fusion of historic and in situ mine field data, control the path planner, and display the planning results. To provide a context for the minefield data, the user interface also renders data from the Digital Nautical Chart database, a database created by the National Geospatial-Intelligence Agency containing charts of the world's ports and coastal regions. This TDA has been developed in conjunction with the COMID (Cooperative Organic Mine Defense) system. This paper presents a description of the algorithms, architecture, and application produced.

Testing of tactical performance in youth elite soccer.  

PubMed

This is a twofold study with the goals of evaluating tactical oriented game test situations for 12-13-year old highly-talented soccer players and to analyze dynamic, intra-individual developments of the players. A cross-sectional design was carried in study 1, using game test situations to measure specific tactics and creative performance for 195 expert players. The results from five evaluation criteria show that both diagnostic instruments can be used for recording football-specific creativity and game intelligence in talented young players. They produced tactical indicators that can be described as objective and valid, exhibit a sufficient degree of differentiation and are easy to record. Study 2 uses a longitudinal design to present a dynamic performance diagnostic tool for analyzing intra-individual improvements of German Soccer Foundation talents according to football-specific creativity and game intelligence. The results with respect to divergent tactical thinking clearly show that very different change processes were observed in the German Soccer Foundation players. Finally, the practical implications for the training process are discussed on the basis of both studies. Key pointsWith game test situations it is possible to assess tactical performance as game intelligence and creativity objective, valid, with a sufficient degree of differentiation, and economically.The results with respect to game intelligence and creativity show that very different change processes were observed in the German Soccer Foundation players dependend on the bases (trainers).Current literature on tactics for school sports as well as for children's, youth and high performance soccer at the club level should place much more emphasis on individual and group-tactical requirements in soccer.

Predicting Seasonal Weather  

NSDL National Science Digital Library

Large-scale weather patterns which occur in various locations around the Earth play a significant part in controlling the weather on a seasonal time scale. A National Science Foundation (NSF)-funded collaborative research effort between Atmospheric and Environmental Research, Inc. (AER), and the Massachusetts Institute of Technology (MIT) has led to a new understanding of the relationship between fall snow cover and winter climate variability. This research has led to the development of a new seasonal forecast model.

Avoidable waste management costs  

SciTech Connect

This report describes the activity based costing method used to acquire variable (volume dependent or avoidable) waste management cost data for routine operations at Department of Energy (DOE) facilities. Waste volumes from environmental restoration, facility stabilization activities, and legacy waste were specifically excluded from this effort. A core team consisting of Idaho National Engineering Laboratory, Los Alamos National Laboratory, Rocky Flats Environmental Technology Site, and Oak Ridge Reservation developed and piloted the methodology, which can be used to determine avoidable waste management costs. The method developed to gather information was based on activity based costing, which is a common industrial engineering technique. Sites submitted separate flow diagrams that showed the progression of work from activity to activity for each waste type or treatability group. Each activity on a flow diagram was described in a narrative, which detailed the scope of the activity. Labor and material costs based on a unit quantity of waste being processed were then summed to generate a total cost for that flow diagram. Cross-complex values were calculated by determining a weighted average for each waste type or treatability group based on the volume generated. This study will provide DOE and contractors with a better understanding of waste management processes and their associated costs. Other potential benefits include providing cost data for sites to perform consistent cost/benefit analysis of waste minimization and pollution prevention (WMIN/PP) options identified during pollution prevention opportunity assessments and providing a means for prioritizing and allocating limited resources for WMIN/PP.

Changing first responder tactics through the use of advanced technologies  

NASA Astrophysics Data System (ADS)

The authors will first analyze current tactics used by emergency personnel when responding to 'standard' emergencies involving transportation systems. Next, the vulnerabilities and the consequences of a terrorist attack on a transportation system. Next the vulnerabilities and the consequences of a terrorist attack on a transportation system in which weapons of mass destruction are employed will be explored. The unique problems associated with the site of an emergency where chemical, nuclear, or biological agents have been employed will be investigated. The use of available or next-ready technologies in the areas of detection devices, personal protective clothing, and decontamination equipment will be examined. Combining this information, we will seek to prove the hypothesis that without the use of new technologies a change in first responder tactics is impossible. However, with the use of advanced technologies we will illustrate how new tactics can produce safe, more effective emergency responses.

Basalt weathering across scales  

NASA Astrophysics Data System (ADS)

Weathering of silicate minerals impacts many geological and ecological processes. For example, the weathering of basalt contributes significantly to consumption of atmospheric carbon dioxide (CO 2) and must be included in global calculations of such consumption over geological timeframes. Here we compare weathering advance rates for basalt ( wD?), where D and ? indicate the scale at which the rate is determined and surface area measured, respectively, from the laboratory to the watershed scales. Data collected at the laboratory, weathering rind, soil profile and watershed scales show that weathering advance rate of basalt is a fractal property that can be described by a fractal dimension ( dr ? 2.3). By combining the fractal description of rates with an Arrhenius relationship for basalt weathering, we derive the following equation to predict weathering advance rates at any spatial scale from weathering advance rates measured at the BET scale: wD?=k(e. Here, k0 is the pre-exponential factor (1.29 × 10 7 mm 3 mm - 2 yr - 1 ), Ea is the activation energy (70 kj mol - 1 ), and a is a spatial constant related to the scale of measurement of BET surface area (10 - 7 mm). The term, (, is the roughness. The roughness fractal dimension can be conceptualized as a factor related to both the thickness of the reaction front and the specific surface area within the reaction front. However, the above equation can also be written in terms of a surface fractal dimension and the hypothetical average grain radius. These fractal dimensions provide insight into reaction front geometry and should vary with lithology. Once the surface area discrepancy has been accounted for using this method, we find a one to two order of magnitude range in weathering advance rates measured at any scale or temperature that can be attributed to factors such as changes in erosional regime, parent lithology, mechanism, climate, composition of reacting fluid, and biological activity. Our scaled equation, when used to predict global basalt CO 2 consumption based upon global lithologic maps, yields an uptake flux (1.75 × 1013 mol CO 2 yr - 1 ) within the predicted error of fluxes estimated based upon riverine measurements.

Oceans, Climate and Weather  

NSDL National Science Digital Library

What is the difference between weather and climate? What do the oceans have to do with them? Weather is the day-to-day state of the atmosphere and its short-term (minutes to weeks) variation. Climate is typically described by the regional patterns of seasonal temperature and precipitation over 30 years. The averages of annual temperature, rainfall, cloud cover, and depth of frost penetration are all typical climate-related statistics. The oceans influence the worlds climate by storing solar energy and distributing it around the planet through currents and atmospheric winds.This publication is all about developing your students understandings of earths oceans and the major effect they have on climate. Understanding and interpreting local weather data and understanding the relationship between weather and climate are important first steps to understanding larger-scale global climate changes. Activities that ask students to collect and analyze local weather data as well as analyze global data can be found in the Lessons and Activities section. Analyzing and interpreting data is a major focus of this publication. Numerous data sets can be found in the Sources for Real Data section. The Background Information section and the article Tomorrows Forecast will help reinforce your own content knowledge.

The notion of complex influence of atmospheric conditions on modem human population, especially the relationship between weather, climate and human healths, has actuated the World Meteorological Organisation to commemorate the coming into force, on March 23, 1950, of the Convention of WMO and this year to celebrate this day by focusing on theme of current interest--"Weather, climate and health". In the light of this, the authors of this paper reveal the results of recent studies dealing with influence of sudden and short-term changes in weather and climate on human health, and future expected climate changes due to "greenhouse" effect, increase in global temperature and tropospheric ozone depletion, as well. Special attention is given to climate shifts due to ENSO (El Niño/Southern Oscillation) phenomenon because of its great impact on human society and epidemics of certain infectious diseases. The results of biometeorological studies dealing with complex influence of daily weather changes on incidence of certain diseases in Croatia have also been presented. In addition, the authors have stated their own view and opinion in regard to future biometeorlogical studies in Croatia in order to achieve better understanding of influence of climate and weather changes on human health, and help prevention of mortality and morbidity related to chronic noninfectious diseases.

Borderline personality disorder features and mate retention tactics.  

PubMed

The purpose of the present study was to examine the association between features of borderline personality disorder (BPD) and mate retention tactics as a means of examining an evolutionary perspective on the association between BPD features and interpersonal problems and violence in romantic relationships. Two-hundred twenty-five college student participants completed the Personality Assessment Inventory for Borderlines (PAI-BOR; Morey, 1991) and the Mate Retention Inventory-Short Form (MRI-SF; Buss, Shackelford, & McKibbin, 2008) embedded within other measures. There was a strong association between BPD features and cost-inflicting mate retention tactics, including the specific tactics of vigilance, punishing mate's infidelity threat, intrasexual threats, and sexual inducements for both men and women. There were also gender-specific associations for additional tactics. These results contribute to our understanding of problems in romantic relationships among men and women with BPD features, including violence, and to our understanding of impulsive sexual behavior among individuals with BPD features by showing how these behaviors are used as extreme, maladaptive attempts at mate retention.

The relationship between social role-taking ability and preferences for interpersonal control tactics was assessed in 50 mentally retarded children. Feffer's Role-Taking Task and two hypothetical interpersonal control episodes were used as experimental measures. Results were that role-taking proficiency was associated with the development of alter-directed tactics or tactics by which the subject appeared to take into account the needs, motivations, or expectations of others. Neither MA nor IQ were significant predictors of interpersonal tactic choice. Controls for IQ and MA did not alter the significance of the association between role-taking and general tactic preferences. PMID:961733

(see Dayong Cao, BAPS.2011.CAL.C1.7, BAPS.2011.DFD.LA.24, BAPS.2012.APR.K1.78 and BAPS.2011.APR.K1.17) The dark Asteroid 2011 AG5 (as a dark comet) is made of the dark matter which has a space-time (as frequence-amplitude square) center- a different systemic model from solar systemic model. It can asborb the space-time and wave. So it is ``dark.'' When many dark matters hit on our earth, they can break our atom structure and our genetic code to trigger the Mass Extinction. In our experiments, consciousness can change the systematic model and code by a life-informational technology. So it can change the output signals of the solar cell. (see Dayong Cao, BAPS.2011.MAR.C1.286 and BAPS.2012.MAR.P33.14) So we will develop the genetic code of lives to evolution and sublimation, will use the dark matter to change the systemic model between dark hole and sun and will avoid next extinction.

Towards a tactical nuclear weapons treaty? Is There a Role of IAEA Tools of Safeguards?  

SciTech Connect

In recent years, there is growing interest in formal negotiations on non-strategic or tactical nuclear weapons. With the negotiations of New START, there has been much speculation that a tactical nuclear weapons treaty should be included in the follow on to New START. This paper examines the current policy environment related to tactical weapons and some of the issues surrounding the definition of tactical nuclear weapons. We then map out the steps that would need to be taken in order to begin discussions on a tactical nuclear weapons treaty. These steps will review the potential role of the IAEA in verification of a tactical nuclear weapons treaty. Specifically, does IAEA involvement in various arms control treaties serve as a useful roadmap on how to overcome some of the issues pertaining to a tactical nuclear weapons treaty?

Whether weather affects music  

NASA Astrophysics Data System (ADS)

The creative output of composers, writers, and artists is often influenced by their surroundings. To give a literary example, it has been claimed recently that some of the characters in Oliver Twist and A Christmas Carol were based on real-life people who lived near Charles Dickens in London [Richardson, 2012]. Of course, an important part of what we see and hear is not only the people with whom we interact but also our geophysical surroundings. Of all the geophysical phenomena to influence us, the weather is arguably the most significant because we are exposed to it directly and daily. The weather was a great source of inspiration for artists Claude Monet, John Constable, and William Turner, who are known for their scientifically accurate paintings of the skies [e.g., Baker and Thornes, 2006].

1980 Weather summary  

NASA Astrophysics Data System (ADS)

The weather in the United States during 1980 was bad. A 3-month heat wave in the southwest caused about $20 billion in ruined crops, an increase in power consumption, and damage to roads and highways. Nationwide, the heat killed 1320 people. Floods caused more than $1 billion in losses. Hurricane Allen caused about $500 million in property losses and took two lives.The highest temperature reading during 1980, 51°C (124°F), was reached five times. Locations were at Bull Head, Arizona; Death Valley, California; and three times at Baker, California. Preliminary figures also show that the lowest temperature for the year was recorded at Tok weather station, 150 miles southeast of Fairbanks, Alaska. There the mercury plummeted to -56°C (-68°F). In the lower 48 states the minimum thermometer reading was -44°C at Wisdom, Montana.

Healthcare avoidance: a critical review.  

PubMed

The purpose of this study is to provide a critical review and synthesis of theoretical and research literature documenting the impact of avoidance on healthcare behaviors, identify the factors that influence healthcare avoidance and delay in the adult population, and propose a direction for future research. The Theory of Reasoned Action, Theory of Planned Behavior, Theory of Care-Seeking Behavior, the Transtheoretical Model, and the Behavioral Model of Health Services Use/Utilization are utilized to elaborate on the context within which individual intention to engage in healthcare behaviors occurs. Research literature on the concept of healthcare avoidance obtained by using computerized searches of CINAHL, MEDLINE, PSYCH INFO, and HAPI databases, from 1995 to 2007, were reviewed. Studies were organized by professional disciplines. Healthcare avoidance is a common and highly variable experience. Multiple administrative, demographic, personal, and provider factors are related to healthcare avoidance, for example, distrust of providers and/or the science community, health beliefs, insurance status, or socioeconomic/income level. Although the concept is recognized by multiple disciplines, limited research studies address its impact on healthcare decision making. More systematic research is needed to determine correlates of healthcare avoidance. Such studies will help investigators identify patients at risk for avoidant behaviors and provide the basis for health-promoting interventions. Methodological challenges include identification of characteristics of individuals and environments that hinder healthcare behaviors, as well as, the complexity of measuring healthcare avoidance. Studies need to systematically explore the influence of avoidance behaviors on specific healthcare populations at risk. PMID:18758277

Pipelines and Space Weather  

NASA Astrophysics Data System (ADS)

Long conductors of all types on Earth's surface are subject to disturbance and disruption by telluric currents (currents that flow within the Earth or on its surface) induced by space weather events. Attention is most often paid to the effects that these currents can produce in electric grids. After all, if an electric power system is disrupted, many other modern infrastructures that depend on the secure and continuous supply of electrical power will also be affected. A recent technical paper in Space Weather by R. A. Marshall and colleagues draws needed attention to the effects of telluric currents on long pipelines. This is a space weather topic that often does not receive the attention it warrants in terms of its critical relevance to modern-day life. Pipelines have long used cathodic protection systems to mitigate the corrosion of the pipes that can arise from potential differences between the ground and the pipes. These potential differences occur because telluric currents flow more readily in the pipes than in the ground. While pipeline engineers have long worked hard on this problem, it was the design and installation in the mid-1970s of the Alaska pipeline directly under the auroral zone that drew enhanced attention to this topic.

Weather service upgrade too costly?  

NASA Astrophysics Data System (ADS)

America needs timely and accurate weather forecasting, said Ernest F. Hollings (D-S.C.), chairman of the Senate Committee on Commerce, Science, and Transportation on National Ocean Policy. Calling the existing warning and forecast system dangerously obsolete, Hollings said that new technology “should dramatically improve the accuracy and timeliness of weather predictions,” as we face the new challenge of bringing the National Weather Service into the 21st century. Hollings' committee heard testimony to consider the modernization of the NWS and pending legislation (S98, S916) on June 18.Major components of the Weather Service Modernization program, according to John A. Knauss, administrator of the National Oceanic and Atmospheric Administration, are the Next Generation Weather Radar (NEXRAD), a new generation of Geostationary Operational Environmental Satellites (GOES-NEXT), the Automated Surface Observing System (ASOS), and the Advanced Weather Interactive Processing System (AWIA). The best defense against severe weather—early warnings—is probably hampered by outdated equipment, he added.

Complexity of biomedical data requires novel sophisticated analysis and presentation methods. Sonification is used as a new information display in augmented reality systems to overcome problems of existing human-computer interface (e.g., opaque or heavy head-mounted displays, slow computer graphics, etc.). A novel taxonomy of sonification methods and techniques is introduced. We present our experience with tactical audio and acoustic rendering in biomedical applications. Tactical audio as an audio feedback is used as support for precise manual positioning of a surgical instrument in the operating room. Acoustic rendering is applied as an additional information channel and/or warning signal in biomedical signal analysis and data presentation. PMID:10719492

Tactics and technology: How do they affect each other  

SciTech Connect

Research and development of new, revolutionary technologies have been extensive. The resulting military applications will drastically change the tactical nature of the battlefield. To cover every technology currently under consideration would be lengthy and beyond the scope of this paper. Rather, it is the intent of this paper to detail selected technological innovations and their tactical implications. Technological advances in space research will allow us to (1) reduce the reaction time in engaging adversary's ballistic missiles by employing boost-phase monitoring technology; (2) establish an overall command and control network for Ballistic Missile Defense (BMD) by incorporating all of our assets into an overall surveillance and tracking system; (3) engage incoming ballistic missiles in a variety of ways, using directed-energy and kinetic energy weapons, both ground and space based; and (4) engage the adversary's satellites from ground, space, and aerial-based means, hampering his ability to use satellite systems for surveillance, reconnaissance, and communication.

Children's responses to everyday marital conflict tactics in the home.  

PubMed

Mothers' and fathers' reports of marital conflicts in the home were obtained (n = 1,638 and 1,281 conflicts, respectively), including conflicts in front of the children (n = 580 and 377, respectively). Participants were 116 families with children 8 to 16 years old (M = 10.82 years, SD = 2.17; 58 boys, 58 girls). Children's emotional responses indicated distinctions between distressing conflict tactics (i.e., threat, personal insult, verbal hostility, defensiveness, nonverbal hostility, marital withdrawal, physical distress) and those that increased their emotional security (i.e., calm discussion, support, affection). Analyses based on cross-reporter informants of parental conflict and child responses strengthened confidence in the findings. Conflict tactics were related to marital functioning, and children's emotional reactions during marital conflicts were associated with their adjustment. PMID:14669904

Research on Digitized Scenario for Tactical Internet Simulative Training  

NASA Astrophysics Data System (ADS)

The scenario of Tactical Internet simulative training can't be realized directly through the scenario systems and methods in existence. For solving this problem, firstly this paper introduced the new concept called digitized scenario, which can describe the meaning of scenario more exactly than the old simulation scenario. Secondly, this paper constructed the framework of digitized scenario, and it settled such issues as composition of digitized scenario system, scenario generating flow and data architecture. Thirdly, this paper built up the general data model for script situation, and it settled the problem of situation setting. Finally, this paper proposed the method of describing scenario files based on eXtensible Markup Language (XML), and it settled such problems as generation, verification and distribution of scenario files. The paper's work has been applied in the Tactical Internet simulative training system, and it also has good directive value to the developing of other communication network simulative training system.

Uncoupling the links between male mating tactics and female attractiveness.  

PubMed Central

Because not all females are equally attractive, and because mating reduces the chances of getting further copulations, males should prefer better-quality mates. In this paper, we use the Trinidadian guppy (Poecilia reticulata) to explore the effects of two non-correlated measures of female quality--size and reproductive status--on male mating decisions. All male guppies employ two alternative mating tactics. We found that large females, particularly those from a high predation site, were the target of most sneaky mating attempts. The response persisted in fish raised under standard conditions over several generations in the laboratory. In addition, non-pregnant females received more courtship displays. We conclude that males can discriminate among females and that they uncouple their mating tactics to track different axes of quality.

Status of TACTIC: A detector for nuclear astrophysics  

NASA Astrophysics Data System (ADS)

A new detector for nuclear astrophysics studies is being designed and built by TRIUMF and the University of York. The TRIUMF Annular Chamber for Tracking and Identification of Charged particles (TACTIC) is designed to detect low-energy charged particles from inverse kinematics reaction studies performed at the relevant astrophysical energies. TACTIC is a cylindrical ionisation/time-projection chamber with segmented anode strips, which allow the dE/dx of the particle to be determined along with the total energy. Information from drift times allows the particle trajectory to be reconstructed. This in turn identifies the interaction point along the beam axis and hence the centre of mass energy of the reaction. To amplify the expected weak signals, a gas electron multiplier (GEM) will be used in place of the usual Frisch grid. Full digital readout of the charge and timing of each anode strip will be achieved with flash ADC cards allowing pulse shape analysis of the signals.

Modified backward error propagation for tactical target recognition  

NASA Astrophysics Data System (ADS)

This thesis explores a new approach to the classification of tactical targets using a new biologically-based neural network. The targets of interest were generated from Doppler imagery and forward looking infrared imagery, and consisted of tanks, trucks, armored personnel carriers, jeeps and petroleum, oil, and lubricant tankers. Each target was described by feature vectors, such as normalized moment invariants. The features were generated from the imagery using a segmenting process. These feature vectors were used as the input to a neural network classifier for tactical target recognition. The neural network consisted of a multilayer perceptron architecture, employing a backward error propagation learning algorithm. The minimization technique used was an approximation to Newton's method. This second order algorithm is a generalized version of well known first order techniques, i.e., gradient of steepest descent and momentum methods. Classification using both first and second order techniques was performed, with comparisons drawn.

Men's Avoidance Coping and Female Partner's Drinking Behavior: A High-Risk Context for Partner Violence?  

PubMed Central

The current study explored whether men's avoidance coping in response to the drinking behavior of their female partner with an alcohol use disorder (AUD) would be associated with higher levels of men's perpetration of intimate partner violence (IPV). Women with an AUD (n = 109) and their male partners in a U.S. urban area were assessed on men's perpetration of minor and severe violence using the Conflict Tactics Scale, men's avoidance coping using the Spouse Behavior Questionnaire, and men's and women's drinking behavior using the Time Line Follow Back Interview. Using multiple regression analysis, results showed that men's use of avoidance coping significantly predicted male IPV perpetration over and above the women's perpetration of violence toward him, while women's alcohol use did not significantly predict male-to-female IPV perpetration. Implications for teaching emotion-regulation strategies to male partners of women with an AUD to cope with partner drinking are discussed.

Cigarette tax avoidance and evasion.  

PubMed

Variation in state cigarette taxes provides incentives for tax avoidance through smuggling, legal border crossing to low tax jurisdictions, or Internet purchasing. When taxes rise, tax paid sales of cigarettes will decline both because consumption will decrease and because tax avoidance will increase. The key innovation of this paper is to compare cigarette sales data to cigarette consumption data from the Behavioral Risk Factor Surveillance System (BRFSS). I show that after subtracting percent changes in consumption, residual percent changes in sales are associated with state cigarette tax changes implying the existence of tax avoidance. I estimate that the tax avoidance response to tax changes is at least twice the consumption response and that tax avoidance accounted for up to 9.6% of sales between 1985 and 2001. Because of the increase in tax avoidance, tax paid sales data understate the level of smoking and overstate the drop in smoking. I also find that the level of legal border crossing was very low relative to other forms of tax avoidance. If states have strong preferences for smoking control, they must pair high cigarette taxes with effective policies to curb smuggling and other forms of tax avoidance or employ alternative policies such as counter-advertising and smoking restrictions.

Collaborative tactical behaviors for autonomous ground and air vehicles  

NASA Astrophysics Data System (ADS)

Tactical behaviors for autonomous ground and air vehicles are an area of high interest to the Army. They are critical for the inclusion of robots in the Future Combat System (FCS). Tactical behaviors can be defined at multiple levels: at the Company, Platoon, Section, and Vehicle echelons. They are currently being defined by the Army for the FCS Unit of Action. At all of these echelons, unmanned ground vehicles, unmanned air vehicles, and unattended ground sensors must collaborate with each other and with manned systems. Research being conducted at the National Institute of Standards and Technology (NIST) and sponsored by the Army Research Lab is focused on defining the Four Dimensional Real-time Controls System (4D/RCS) reference model architecture for intelligent systems and developing a software engineering methodology for system design, integration, test and evaluation. This methodology generates detailed design requirements for perception, knowledge representation, decision making, and behavior generation processes that enable complex military tactics to be planned and executed by unmanned ground and air vehicles working in collaboration with manned systems.

Paternal inheritance of growth in fish pursuing alternative reproductive tactics.  

PubMed

In species with indeterminate growth, age-related size variation of reproductive competitors within each sex is often high. This selects for divergence in reproductive tactics of same-sex competitors, particularly in males. Where alternative tactics are fixed for life, the causality of tactic choice is often unclear. In the African cichlid Lamprologus callipterus, large nest males collect and present empty snail shells to females that use these shells for egg deposition and brood care. Small dwarf males attempt to fertilize eggs by entering shells in which females are spawning. The bourgeois nest males exceed parasitic dwarf males in size by nearly two orders of magnitude, which is likely to result from greatly diverging growth patterns. Here, we ask whether growth patterns are heritable in this species, or whether and to which extent they are determined by environmental factors. Standardized breeding experiments using unrelated offspring and maternal half-sibs revealed highly divergent growth patterns of male young sired by nest or dwarf males, whereas the growth of female offspring of both male types did not differ. As expected, food had a significant modifying effect on growth, but neither the quantity of breeding substrate in the environment nor ambient temperature affected growth. None of the environmental factors tested influenced the choice of male life histories. We conclude that in L. callipterus growth rates of bourgeois and parasitic males are paternally inherited, and that male and female growth is phenotypically plastic to only a small degree.

Brazilian Space Weather Program  

NASA Astrophysics Data System (ADS)

A space weather program is being initiated at the Brazilian National Institute for Space Research (INPE) to study events from their initiation on the sun to their impacts on the earth, including their effects on space-based and ground-based technological systems. The program is built on existing capabilities at INPE, which include scientists with a long tradition and excellence in the observation, analysis and modeling of solar and solar-terrestrial phenomena and an array of geophysical instruments that spans all over the Brazilian territory from the north to south of the magnetic dip equator. Available sensors include solar radio frequency receivers and telescopes, optical instruments and solar imagers, GNSS receivers, ionosondes, radars, allsky imagers, magnetometers and cosmic ray detectors. In the equatorial region, ionosphere and thermosphere constitute a coupled system with electrodynamical and plasma physical processes being responsible for a variety of peculiar phenomena. The most important of them are the equatorial electrojet current system and its instabilities, the equatorial ionization anomaly, and the plasma instabilities/irregularities of the night-time ionosphere (associated with the plasma bubble events). In addition, space weather events modify the equatorial ionosphere in a complex and up to now unpredictable manner. Consequently, a main focus of the program will be on monitoring the low, middle and upper atmosphere phenomena and developing a predictive model of the equatorial ionosphere through data assimilation, that could help to mitigate against the deleterious effects on radio communications and navigation systems. The technological, economic and social importance of such activities was recognized by the Brazilian government and a proposal for funding was approved for the period 2008-2011. New ground instruments will be installed during this period allowing us to extend our current capability to provide space weather observations, accurate forecasts of space weather conditions, and timely hazard alert warnings. The program is expected to be fully operational for the peak activity of the next solar maximum, but for its future growth and development it is essential to have a wide network of international collaborations.

This tutorial introduces students to global weather patterns and how they affect the kinds of trees and plants that grow in different latitudes of the Earth. The discussion covers the tropics and the lush rainforests that live there, temperate forests in the mid-latitudes, and boreal forests in the far north. There is also a description of how treeless areas occur in various climate zones (desert, tundra, savannah), and how plants adapt to low-water conditions in the desert. A quiz and glossary are included.

A validity generalization procedure to test relations between intrinsic and extrinsic motivation and influence tactics.  

PubMed

The relations of intrinsic and extrinsic motivation with use of consultative, legitimating, and pressure influence tactics were examined using validity generalization procedures. 5 to 7 field studies with cumulative samples exceeding 800 were used to test each relationship. Significance was found for relation between agents' intrinsic motivation and their use of consultative influence tactics and agents' extrinsic motivation and their use of legitimating influence tactics.

Mating tactics of male feral goats ( Capra hircus ): risks and benefits  

Microsoft Academic Search

Intense competition between males for reproduction has led to the evolution of alternative mating tactics (AMTs). Feral goat\\u000a males usually use a tactic called tending, in which they defend oestrous females from other males. Males may also use a second\\u000a mating tactic called coursing, in which they gain access to oestrous females by disturbing a tending pair. Herein, we examine

Mating in bighorn sheep: frequent male reproduction via a high-risk “unconventional” tactic  

Microsoft Academic Search

Rocky Mountain bighorn rams use three distinct tactics in competition for mates. Two tactics (tending and blocking) feature\\u000a defense and cooperative mating over a relatively prolonged consort period (up to 3 days). In the coursing tactic, subordinate\\u000a rams fight dominants for temporary copulatory access (lasting seconds) to defended ewes. By combining population-wide genetic\\u000a (microsatellite) exclusion of paternity, behavioral data and

Efficient transmission of DoD PKI certificates in tactical networks  

Microsoft Academic Search

The DoD vision of real-time information sharing and net-centric services available to warfighters at the tactical edge is challenged by low-bandwidth and high-latency tactical network links. Secured tactical applications require transmission of digital certificates that contribute a major portion of data in most secure sessions, which further increases response time for users and drains device power. In this paper we
