    The joint tactical information distribution system ( JTIDS) achieves relative navigation function, but the random errors caused by position of message source influence the performance of navigation in navigation calculation. In view of this problem, CLRB’ s expression was deduced under the circumstance of relative navigation of JTIDS, and aquantitative analysis was made on the effect of the source loca-tion’ s errors on navigation calculation. Moreover, a two-step least-square algorithm of position determination was used so as to eliminate er-rors of the source location. Simulation results show that the source location’ s errors affect much on navigation calculation, therefore, the algorithm in this paper will effectively restrain the source location’ s errors.%利用联合战术信息分发系统( JTIDS)实现相对导航功能时,消息源自身位置存在的随机误差会在导航解算中对导航质量产生影响。针对此问题,文中推导出JTIDS相对导航环境下克拉美-罗界( CLRB)的表达式,定量的分析了源位置误差对导航解算的影响,并采用一种两步最小二乘的定位解算方法,用以消除源位置误差带来的影响。仿真结果表明,源位置误差对导航解算影响较大,而采用文中算法能够有效的抑制源位置误差的影响。

    Friehmelt, Holger; Guetter, Richard; Kim, Quirin

    1997-01-01

    The two X-31A were jointly built by Daimler-Benz Aerospace AG and Rockwell International. These German-American experimental aircraft were designed to explore the new realm of flight far beyond stall by employing advanced technologies like thrust vectoring and sophisticated flight control systems. The X-31A aircraft is equipped with a thrust vectoring system consisting of three aft mounted paddles to deflect the thrust vector in both pitch and yaw axes, thus providing the X-31A in this 'Enhanced Fighter Maneuverability program with an agility and maneuverability never seen before. The tactical utility of the X-31A using post stall technologies has been revealed in an extensive flight test campaign against various current state-of-the-art fighter aircraft in a close-in combat arena. The test philosophy included both simulation and flight test. The tremendous tactical advantage of the X-31A during the tactical utility evaluation flight test phase was accompanied by a deepened insight into post stall tactics its typical maneuvers, impacts on pilot-aircraft interfaces and requirements for future weapons to both engineers and the military community. Some selected aspects of the tactical utility of the X-31A using post stall technologies unveiled by the International Test Organization are presented here.

    Mocenter, Michael M.

    1990-02-01

    The ability to send photographic information to command centers is a vital element in performing effective near real-time reconnaissance and surveillance operations. This imagery, in conjunction with other battlefield data, provides the battlefield commander with up-to-date intelligence for making decisions. Until recently, the ability to provide this real-time information was severely restricted by the logistics of physically moving, developing, and then disseminating the film. This time delay resulted in out-of-date, stale intelligence. This problem situation has eased recently due to technological developments that have been instrumental in facilitating the dissemination of near real-time information to forward operating areas and behind enemy lines. The Naval Air Development Center (NAVAIRDEVCEN) has capitalized on these developments and established the Tactical Imaging System (TIS). This miniaturized, man-pack, SATCOM/HF transmitting system provides near real-time tactical imagery. It consists of an image sensor, image intensifier, zoom lens, and image transmission processor. This paper provides an overview of the TIS components, specifications, operations, and future developments and applications. The TIS will have potential application in areas such as identification (friend or foe), reconnaissance, surveillance, and battlefield assessment. Under the TIS program, NAVAIRDEVCEN has developed hands-on experience in still video images and related technologies, including fleet satellite communications, HF transmission, image compression algorithms, VSLI integrated circuitry design, and day/night imagery techniques. NAVAIRDEVCEN has developed a complete, miniaturized system to conduct operational demonstrations, and to demonstrate operational tactics and utilization concepts. This paper provides an overview of the TIS components, specifications, operations, and future developments and applications.

    Tactical Satellite 3 is an Air Force Research Laboratory Science and Technology (S&T) initiative that explores the capability and technological maturity of small, low-cost satellites. It features a low cost "plug and play" modular bus and low cost militarily significant payloads - a Raytheon developed Hyperspectral imager and secondary payload data exfiltration provided by the Office of Naval Research. In addition to providing for ongoing innovation and demonstration in this important technology area, these S&T efforts also help mitigate technology risk and establish a potential concept of operations for future acquisitions. The key objectives are rapid launch and on-orbit checkout, theater commanding, and near-real time theater data integration. It will also feature a rapid development of the space vehicle and integrated payload and spacecraft bus by using components and processes developed by the satellite modular bus initiative. Planned for a late summer 2008 launch, the TacSat-3 spacecraft will collect and process images and then downlink processed data using a Common Data Link. An in-theater tactical ground station will have the capability to uplink tasking to spacecraft and will receive full data image. An international program, the United Kingdom Defence Science and Technology Laboratory (DSTL) and Australian Defence Science and Technology Organisation (DSTO) plan to participate in TacSat-3 experiments.

    2010-04-01

    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.

  11. Polyandry and alternative mating tactics.

    Science.gov (United States)

    Neff, Bryan D; Svensson, Erik I

    2013-03-05

    Many species in the animal kingdom are characterized by alternative mating tactics (AMTs) within a sex. In males, such tactics include mate guarding versus sneaking behaviours, or territorial versus female mimicry. Although AMTs can occur in either sex, they have been most commonly described in males. This sex bias may, in part, reflect the increased opportunity for sexual selection that typically exists in males, which can result in a higher probability that AMTs evolve in that sex. Consequently, females and polyandry can play a pivotal role in governing the reproductive success associated with male AMTs and in the evolutionary dynamics of the tactics. In this review, we discuss polyandry and the evolution of AMTs. First, we define AMTs and review game theoretical and quantitative genetic approaches used to model their evolution. Second, we review several examples of AMTs, highlighting the roles that genes and environment play in phenotype expression and development of the tactics, as well as empirical approaches to differentiating among the mechanisms. Third, ecological and genetic constraints to the evolution of AMTs are discussed. Fourth, we speculate on why female AMTs are less reported on in the literature than male tactics. Fifth, we examine the effects of AMTs on breeding outcomes and female fitness, and as a source, and possibly also a consequence, of sexual conflict. We conclude by suggesting a new model for the evolution of AMTs that incorporates both environmental and genetic effects, and discuss some future avenues of research.

  12. TACTICS OF CONFRONTATION

    Directory of Open Access Journals (Sweden)

    Golovin M. V.

    2015-12-01

    Full Text Available As a part of the investigation carried out in the course of the investigation of crimes, a confrontation is very important. This article reveals the essence of the scientific production of the confrontation, the object and purpose of which is to establish the truth in the case. The investigator, in accordance with the Article 192 of the Code of Criminal Procedure of the Russian Federation has the right to decide on proceeding a confrontation, in cases when previously there were significant differences. In conducting confrontation, there are confirmed correct versions and the versions denied by others, it turns out the real facts of the case and eliminates significant contradictions in the testimony of previously interrogated persons. By making the decision to produce a confrontation, the investigator must be confident in the ability of the participant, who gave truthful testimony, to withstand the psychological pressure. This party should be prepared to create his "immunity" against future attempts to influence the other party to persuade to change readings, etc. Before the production of a confrontation, the investigator must draw up a plan in which the questions are formulated. Then prioritize questioning of participants of confrontation and identify tactics that can be applied in the course of its production. The investigator prepares a space for the production of confrontation, and audio, photo and video equipment. Different violations, errors during the confrontation, have the ultimate impact on the overall result of the preliminary investigation of a specific criminal case. In this regard, clarification of the nature of the confrontation has not only theoretical but also practical importance

    2011-06-01

    This paper proposes a strategy to unify four disparate networks under an Internet Protocol (IP) umbrella. The first network is the Army Warfighter Information Network - Tactical (WIN-T) area common user system. The second network is an extension to the area common user system using the Mobile Ad Hoc Interoperability Networking Gateway (MAINGATE) system. The third network is the Worldwide Interoperability for Microwave Access (WiMax) based wireless access network and the forth network is the 802.11 WiFi Network. It is the intent of this paper to propose a skeletal wireless strategy that at its core will create everything over IP (EoIP) and "Everything over IEEE" ("EoIEEE") standards at the tactical level of the battlefield.

    Information at the tactical level is increasingly critical in today's conflicts. The proliferation of commercial tablets and smart phones has created the ability for extensive information sharing at the tactical edge, beyond the traditional tactical voice communications and location information. This is particularly the case in Gray Zone conflicts, in which tactical decision making and actions are intertwined with information sharing and exploitation. Networking of tactical devices is the key to this information sharing. In this work, we detail and analyze two network models at different parts of the Gray Zone spectrum, and explore a number of networking options including Named Data Networking. We also compare networking approaches in a variety of realistic operating environments. Our results show that Named Data Networking is a good match for the disrupted networking environments found in many tactical situations

    2012-05-01

    The present study explored how football players' dynamic positional data can be used to assess tactical behaviour by measuring movement patterns and inter-player coordination. A pre post-test design was used to assess the effects of a 13-week constructivist and cognitivist training program by measuring behaviour in a 5 × 5 football small-sided game, played on a 60 × 40 m outdoor natural turf pitch. Data was captured at 5 Hz by GPS devices (SPI Pro, GPSports, Canberra, Australia) and analysed with non-linear signal processing methods. Approximate entropy values were lower in post-test situations suggesting that these time series became more regular with increasing expertise in football. Relative phase post-test values showed frequent periods with a clear trend to moving in anti-phase, as measured by players' distance to the centre of the team. These advances may open new research topics under the tactical scope and allow narrowing the gap between sports sciences and sports coaching. © Georg Thieme Verlag KG Stuttgart · New York.

  14. Predicting Reliability of Tactical Network Using RBFNN

    Institute of Scientific and Technical Information of China (English)

    WANG Xiao-kai; HOU Chao-zhen

    2005-01-01

    A description of the reliability evaluation of tactical network is given, which reflects not only the non-reliable factors of nodes and links but also the factors of network topological structure. On the basis of this description, a reliability prediction model and its algorithms are put forward based on the radial basis function neural network (RBFNN) for the tactical network. This model can carry out the non-linear mapping relationship between the network topological structure, the nodes reliabilities, the links reliabilities and the reliability of network. The results of simulation prove the effectiveness of this method in the reliability and the connectivity prediction for tactical network.

  15. Tactical Synthesis Of Efficient Global Search Algorithms

    Nedunuri, Srinivas; Smith, Douglas R.; Cook, William R.

    2009-01-01

    Algorithm synthesis transforms a formal specification into an efficient algorithm to solve a problem. Algorithm synthesis in Specware combines the formal specification of a problem with a high-level algorithm strategy. To derive an efficient algorithm, a developer must define operators that refine the algorithm by combining the generic operators in the algorithm with the details of the problem specification. This derivation requires skill and a deep understanding of the problem and the algorithmic strategy. In this paper we introduce two tactics to ease this process. The tactics serve a similar purpose to tactics used for determining indefinite integrals in calculus, that is suggesting possible ways to attack the problem.

    2010-01-01

    How often will elections end in landslides? What is the probability for a head-to-head race? Analyzing ballot results from several large countries rather anomalous and yet unexplained distributions have been observed. 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.

    For sports assessment to be comprehensive, it must address all variables of sports development, such as psychological, social-emotional, physical and physiological, technical and tactical. Tactical assessment has been a neglected variable until the 1980s or 1990s. In the last two decades (1995-2015), the evolution of tactical assessment has grown considerably, given its importance in game performance. The aim of this paper is to compile and analyze different tactical measuring tools in team sports, particularly in soccer, through a bibliographical review. Six tools have been selected on five different criteria: (1) Instruments which assess tactics, (2) The studies have an evolution approach related to the tactical principles, (3) With a valid and reliable method, (4) The existence of publications mentioning the tool in the method, v. Applicable in different sports contexts. All six tools are structured around seven headings: introduction, objective(s), tactical principles, materials, procedures, instructions/rules of the game and published studies. In conclusion, the teaching-learning processes more tactical oriented have useful tactical assessment instrument in the literature. The selection of one or another depends some context information, like age and level of expertise of the players.

    We report progress toward the development of a compression schema suitable for use in the Army's Common Operating Environment (COE) tactical network. The COE facilitates the dissemination of information across all Warfighter echelons through the establishment of data standards and networking methods that coordinate the readout and control of a multitude of sensors in a common operating environment. When integrated with a robust geospatial mapping functionality, the COE enables force tracking, remote surveillance, and heightened situational awareness to Soldiers at the tactical level. Our work establishes a point cloud compression algorithm through image-based deconstruction and photogrammetric reconstruction of three-dimensional (3D) data that is suitable for dissimination within the COE. An open source visualization toolkit was used to deconstruct 3D point cloud models based on ground mobile light detection and ranging (LiDAR) into a series of images and associated metadata that can be easily transmitted on a tactical network. Stereo photogrammetric reconstruction is then conducted on the received image stream to reveal the transmitted 3D model. The reported method boasts nominal compression ratios typically on the order of 250 while retaining tactical information and accurate georegistration. Our work advances the scope of persistent intelligence, surveillance, and reconnaissance through the development of 3D visualization and data compression techniques relevant to the tactical operations environment.

  5. Distributed tactical reasoning framework for intelligent vehicles

    Science.gov (United States)

    Sukthankar, Rahul; Pomerleau, Dean A.; Thorpe, Chuck E.

    1998-01-01

    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.

    Kurdziel, Michael T.

    2014-05-01

    The shift to a full information-centric paradigm in the battlefield has allowed ConOps to be developed that are only possible using modern network communications systems. Securing these Tactical Networks without impacting their capabilities has been a challenge. Tactical networks with fixed infrastructure have similar vulnerabilities to their commercial counterparts (although they need to be secure against adversaries with greater capabilities, resources and motivation). However, networks with mobile infrastructure components and Mobile Ad hoc Networks (MANets) have additional unique vulnerabilities that must be considered. It is useful to examine Tactical Network based ConOps and use them to construct a threat model and baseline cyber security requirements for Tactical Networks with fixed infrastructure, mobile infrastructure and/or ad hoc modes of operation. This paper will present an introduction to threat model assessment. A definition and detailed discussion of a Tactical Network threat model is also presented. Finally, the model is used to derive baseline requirements that can be used to design or evaluate a cyber security solution that can be scaled and adapted to the needs of specific deployments.

    Kaneshige, John; KrishnaKumar, K.; Shung, Felix

    2003-01-01

    This paper describes a tactical maneuvering system that uses an artificial immune system based approach for selecting maneuver sequences. This approach combines the problem solving abilities of genetic algorithms with the memory retention characteristics of an immune system. Of significant importance here is the fact that the tactical maneuvering system can make time-critical decisions to accomplish near-term objectives within a dynamic environment. These objectives can be received from a human operator, autonomous executive, or various flight planning specialists. Simulation tests were performed using a high performance military aircraft model. Results demonstrate the potential of using immunized sequence selection in order to accomplish tactical maneuvering objectives ranging from flying to a location while avoiding unforeseen obstacles, to performing relative positioning in support of air combat maneuvering.

    Limited conflicts and the war against terrorism, in particular, have changed the emphasis in the present trend from preparing to cope with full-scale wars to the need to combat in limited conflicts. This shift has affected significantly medical units' preparations. Law enforcement organizations have come together with medical first responders in a combined new model. This model is supposed to be adopted and utilized in combat and evolved from the civilian model toward a modus operandi that combines the tactical and medical protocols into a single algorithm, the "Tactical Combat Casualty Care" (TCCC). This TCCC model is believed to enhance the mutual understanding and cooperation of tactical and medical forces in combat and especially amongst special military units. Utilizing the model will be achieved by the development of well-matched standard operating procedures and sharing drills. All these acts are hoped to improve safety of the participating units and hopefully also the medical outcomes.

    2005-07-01

    Full Text Available The problem of tactical missile guidance is very challenging and has been treated using several basic metlfodologies in the past four decades. Major techniques can be grouped underclassical guidance laws, modern guidance laws, l'aws for manoeuvring targets, predictive guidance for endgame scenario, and guidance laws based on intelligent control methods. Each technique has some advantages and disadvantages while implementing in a practical system. Guidance law selection is dictated by nature of flight profile like boost, midcourse, terminal homing, etc, and also miss-distance and a single-shot kill probability. This paper presents a brief survey of the existing techniques and current trends in tactical missile guidance.

    Ameloblastoma and ameloblastic fibroma are benign odontogenous tumors of the jaws with local destructive growth, prone to recurrence. They have various typical radiological and histological features. Surgical tactic generally includes partial resection of the affected jaw. Immunohistochemical study of the tumor tissues allows assessing the expression of tumor progression markers and forecasting tumor growth thus providing individual choice of surgical tactics. Our experience in treatment of ameloblastic tumors showed total biopsy with osseous surgical margins resection to be sufficient for normal bone structure remodeling in some patients.

  15. A Universal Martial Tactic: The Shoulder Throw & Its Variations, by Allen Pittman

    Directory of Open Access Journals (Sweden)

    Allen Pittman

    2012-07-01

    Full Text Available Development of the fighting arts begins with universal principles found in human anatomy. As a result, in every culture we find combative techniques that share common tactics and applications. Additionally, many techniques travel across cultures. To illustrate just one martial tactic and its worldwide presence among martial traditions, this article presents variations on the shoulder throw as found in Persia, Greece, Japan, China, England, and France. Two main methods are found in the shoulder throw where the defender moves either inside or outside the attacker’s leading arm. The technical variations seem endless, as the defender can not only throw an opponent, but also employ joint locks, breaks, and even weapons in the techniques. An academic understanding, and/or the practical learning, of trans-cultural techniques, brings greater understanding of martial arts in general and a practical component to those who learn the skills for practical application.

  16. Airborne Tactical Free-Electron Laser

    Energy Technology Data Exchange (ETDEWEB)

    Whitney, Roy; Neil, George

    2007-02-01

    The goal of 100 kilowatts (kW) of directed energy from an airborne tactical platform has proved challenging due to the size and weight of most of the options that have been considered. However, recent advances in Free-Electron Lasers appear to offer a solution along with significant tactical advantages: a nearly unlimited magazine, time structures for periods from milliseconds to hours, radar like functionality, and the choice of the wavelength of light that best meets mission requirements. For an Airborne Tactical Free-Electron Laser (ATFEL) on a platforms such as a Lockheed C-130J-30 and airships, the two most challenging requirements, weight and size, can be met by generating the light at a higher harmonic, aggressively managing magnet weights, managing cryogenic heat loads using recent SRF R&D results, and using FEL super compact design concepts that greatly reduce the number of components. The initial R&D roadmap for achieving an ATFEL is provided in this paper. Performing this R&D is expected to further reduce the weight, size and power requirements for the FELs the Navy is currently developing for shipboard applications, as well as providing performance enhancements for the strategic airborne MW class FELs. The 100 kW ATFEL with its tactical advantages may prove sufficiently attractive for early advancement in the queue of deployed FELs.

  18. Euthanasia tactics: patterns of injustice and outrage.

    Science.gov (United States)

    Martin, Brian

    2013-12-01

    Struggles over euthanasia can be examined in terms of tactics used by players on each side of the issue to reduce outrage from actions potentially perceived as unjust. From one perspective, the key injustice is euthanasia itself, especially when the person or relatives oppose death. From a different perspective, the key injustice is denial of euthanasia, seen as a person's right to die. Five types of methods are commonly used to reduce outrage from something potentially seen as unjust: covering up the action; devaluing the target; reinterpreting the action, including using lying, minimising consequences, blaming others and benign framing; using official channels to give an appearance of justice; and using intimidation. Case studies considered include the Nazi T4 programme, euthanasia in contemporary jurisdictions in which it is legal, and censorship of Exit International by the Australian government. By examining euthanasia struggles for evidence of the five types of tactics, it is possible to judge whether one or both sides use tactics characteristic of perpetrators of injustice. This analysis provides a framework for examining tactics used in controversial health issues.

    Lockheed Martin's Advanced Technology Center has developed a very lightweight cryocooler for tactical and space cooling applications. A prototype pulse tube cryocooler was built and tested, utilizing a new microcompressor with a mass of less than 200 grams. The "Oxford type" compressor uses the same long-life features of Lockheed Martin's larger compressors: long-life flexure-bearing clearance-seal technology, with a simple moving magnet configuration designed both for low-cost tactical applications and for long-life space applications. The compressor operated flawlessly with electrical input power as high as 25 W. Test data will be presented for the prototype single-stage pulse tube cooler. Predictions for the cooling capability of optimized coldheads under a variety of cold tip temperatures and heat loads will also be presented. A first-article microcryocooler with an optimized coldhead is slated to be integrated into a high-performance infrared (IR) camera system by the end of 2013.

    2008-01-01

    The aim of this paper is to give an overview on models and methods used to solve tactical planning problems. The modeling and the elaboration of the well-know tactical planning problems (master planning & scheduling, material requirement planning and multi-site planning) are discussed. These problems are modeled from two "lot sizing" models called the Capacitated Lot Sizing Problem (CLSP) and Multi Level Capacitated Lot Sizing Problem (MLCLSP). From both models, a lot of extensions has been proposed in the literature. The purpose of this paper is twofold: first, classifications of the CLSP and MLCLSP as well as their extensions are given. For each model, the major scientific contributions are mentioned. These classifications made from seventy papers give an overview of "lot sizing" models dedicated to the MPS, MRP and Multi-site and show the diversity of models. Second, from a classification, an analysis of methods used for each model is given. The instance size, best gap and reference for gap computation are given for each contribution. This work can be used to elaborate an optimization tool for tactical planning problematic such as Advanced Planning System.

    One explanation for hybridization between species is the fitness benefits it occasionally confers to the hybridizing individuals. This explanation is possible in species that have evolved alternative male reproductive tactics: individuals with inferior tactics might be more prone to hybridization provided it increases their reproductive success and fitness. Here we experimentally tested whether the propensity of hybridization in the wild depends on male reproductive tactic in Calopteryx splendens damselflies. Counter to our expectation, it was males adopting the superior reproductive tactic (territoriality) that had greatest propensity to hybridize than males adopting the inferior tactics (sneakers and floaters). Moreover, among the territorial males, the most ornamented males had greatest propensity to hybridize whereas the pattern was reversed in the sneaker males. Our results suggest that there is fluctuating selection on male mate discrimination against heterospecific females depending on both ornament size and the male's reproductive tactic.

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

    2008-04-01

    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

    Biliary tract diseases in children in recent years increasingly attracted the attention of not only physicians and surgeons, but this problem is becoming increasingly important in pediatric practice. Thus, gallstone disease in childhood is becoming a serious medical and social problem because of its chronic relapsing course, the development of severe complications, reduced quality of life and social adaptation of children. A particular difficulty is to select treatment tactics at cholelithiasis in childhood. The aim of this study was to demonstrate on the basis of own experience observing children with cholelithiasis, advantages and disadvantages of both surgical and conservative treatment of cholelithiasis in children, suggest alternative approaches for different periods of childhood.

    Full Text Available This study aimed to identify the tactical patterns and the timescales of variables during a soccer match, allowing understanding the multilevel organization of tactical behaviors, and to determine the similarity of patterns performed by different groups of teammates during the first and second halves. Positional data from twenty professional male soccer players from the same team were collected using high frequency global positioning systems (5Hz. Twenty-nine categories of tactical behaviors were determined from eight positioning-derived variables creating multivariate binary (Boolean time-series matrices. Hierarchical principal component analysis was used to identify the multilevel structure of tactical behaviors. The sequential reduction of each set level of principal components revealed a sole principal component as the slowest collective variable, forming the global basin of attraction of tactical patterns during each half of the match. In addition, the mean dwell time of each positioning-derived variable helped to understand the multilevel organization of collective tactical behavior during a soccer match. This approach warrants further investigations to analyze the influence of task constraints on the emergence of tactical behavior. Furthermore, principal component analysis can help coaches to design representative training tasks according to those tactical patterns captured during match competitions and to compare them depending on situational variables.

  16. AGATE: Adversarial Game Analysis for Tactical Evaluation

    Science.gov (United States)

    Huntsberger, Terrance L.

    2013-01-01

    AGATE generates a set of ranked strategies that enables an autonomous vehicle to track/trail another vehicle that is trying to break the contact using evasive tactics. The software is efficient (can be run on a laptop), scales well with environmental complexity, and is suitable for use onboard an autonomous vehicle. The software will run in near-real-time (2 Hz) on most commercial laptops. Existing software is usually run offline in a planning mode, and is not used to control an unmanned vehicle actively. JPL has developed a system for AGATE that uses adversarial game theory (AGT) methods (in particular, leader-follower and pursuit-evasion) to enable an autonomous vehicle (AV) to maintain tracking/ trailing operations on a target that is employing evasive tactics. The AV trailing, tracking, and reacquisition operations are characterized by imperfect information, and are an example of a non-zero sum game (a positive payoff for the AV is not necessarily an equal loss for the target being tracked and, potentially, additional adversarial boats). Previously, JPL successfully applied the Nash equilibrium method for onboard control of an autonomous ground vehicle (AGV) travelling over hazardous terrain.

  17. Screening closing scenarios for tactical targets

    Sefcik, Jason A.; Lee, Harry C.; Olson, Teresa L. P.

    2002-07-01

    The first step in an automatic image target acquisition system is determining the location of candidate objects. Screening for targets must also be done within a tactical scenario timeframe. The screening process must only require a portion of the processing workload since other algorithms must execute in the same time frame. The detection of these candidate objects is allocated to two functions within the same algorithm. The first is a pre-screener and other is a clutter rejection component that will categorize the object nomination into target or non-target classes. This paper describes a screener that meets the necessary requirements for tactical operations. It uses the magnitude and direction of the image gradient. Locations are nominated by looking at local neighborhoods in this gradient space. Regions of interest are then selected and various features are extracted. These features are selected both for their information content and their ease of calculation. Using a Bayes approach, target candidates are selected as plausible targets of interest.

  18. Automated Reasoning Across Tactical Stories to Derive Lessons Learned

    Directory of Open Access Journals (Sweden)

    J. Wesley Regian

    2008-06-01

    Full Text Available The Military Analogical Reasoning System (MARS is a performance support system and decision aid for commanders in Tactical Operations Centers. MARS enhances and supports the innate human ability for using stories to reason about tactical goals, plans, situations, and outcomes. The system operates by comparing many instances of stored tactical stories, determining which have analogous situations and lessons learned, and then returning a description of the lessons learned. The description of the lessons learned is at a level of abstraction that can be generalized to an appropriate range of tactical situations. The machine-understandable story representation is based on a military operations data model and associated tactical situation ontology. Thus each story can be thought of, and reasoned about, as an instance of an unfolding tactical situation. The analogical reasoning algorithm is based on Gentner's Structure Mapping Theory. Consider the following two stories. In the first, a U.S. platoon in Viet Nam diverts around a minefield and subsequently comes under ambush from a large hill overlooking their new position. In the second, a U.S. task force in Iraq diverts around a biochemical hazard and subsequently comes under ambush from the roof of an abandoned building. MARS recognizes these stories as analogical, and derives the following abstraction: When enemy-placed obstacles force us into an unplanned route, beware of ambush from elevation or concealment. In this paper we describe the MARS interface, military operations data model, tactical situation ontology, and analogical reasoning algorithm.

    2009-05-01

    Net-Centric Information Management (IM) and sharing in tactical environments promises to revolutionize forward command and control capabilities by providing ubiquitous shared situational awareness to the warfighter. This vision can be realized by leveraging the tactical and Mobile Ad hoc Networks (MANET) which provide the underlying communications infrastructure, but, significant technical challenges remain. Enabling information management in these highly dynamic environments will require multiple support services and protocols which are affected by, and highly dependent on, the underlying capabilities and dynamics of the tactical network infrastructure. In this paper we investigate, discuss, and evaluate the effects of realistic tactical and mobile communications network environments on mission-critical information management systems. We motivate our discussion by introducing the Advanced Information Management System (AIMS) which is targeted for deployment in tactical sensor systems. We present some operational requirements for AIMS and highlight how critical IM support services such as discovery, transport, federation, and Quality of Service (QoS) management are necessary to meet these requirements. Our goal is to provide a qualitative analysis of the impact of underlying assumptions of availability and performance of some of the critical services supporting tactical information management. We will also propose and describe a number of technologies and capabilities that have been developed to address these challenges, providing alternative approaches for transport, service discovery, and federation services for tactical networks.

J Strength Cond Res 30(7): 1975-1984, 2016-The aim of this study was to compare time-motion and technical-tactical analysis between paired outcomes and rounds of mixed martial arts (MMA) matches. The sample consisted of 645 rounds of MMA competition paired by outcomes (first round, winners n = 215 and losers n = 215; second round, winners n = 215 and losers n = 215; third round, winners n = 215 and losers n = 215). The time-motion variables were categorized into low-intensity or high-intensity, stand-up or groundwork situations. Stand-up techniques were analyzed by observing total strikes to the head and body, and takedowns. The actions on the ground were analyzed by observing submission activity, including successful choking and joint locking actions, and also positional improvements, including advances to the mount, half guard, and side and back positions. Chi-squared and Wilcoxon tests were conducted with a significance level of p ≤ 0.05. Results showed that winners had higher values for total strikes and submissions in all rounds, and also positional improvements, over losers. The standing combat with low-intensity comparisons presented differences between the rounds first, with a median of 2:33.5 (P25-P75%: 1:20-3:56) minute, second, with 2:37 (1:24-3:59) minute, and third, with 2:07 (1:06-3:39.2) minute. These data suggest a focus on the intermittent demand presented in combat phases with a special attention to the strike and ground technical-tactical skills; strength and conditioning coaches could emphasize the effort pause ratios for both standing and ground combat that mimic the requirements of MMA, especially during the third round.

    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.

    We have reviewed the experimental and modeling evidence on the use of mixtures of fungicides of differing modes of action as a resistance management tactic. The evidence supports the following conclusions. 1. Adding a mixing partner to a fungicide that is at-risk of resistance (without lowering the dose of the at-risk fungicide) reduces the rate of selection for fungicide resistance. This holds for the use of mixing partner fungicides that have either multi-site or single-site modes of action. The resulting predicted increase in the effective life of the at-risk fungicide can be large enough to be of practical relevance. The more effective the mixing partner (due to inherent activity and/or dose), the larger the reduction in selection and the larger the increase in effective life of the at-risk fungicide. 2. Adding a mixing partner while lowering the dose of the at-risk fungicide reduces the selection for fungicide resistance, without compromising effective disease control. The very few studies existing suggest that the reduction in selection is more sensitive to lowering the dose of the at-risk fungicide than to increasing the dose of the mixing partner. 3. Although there are very few studies, the existing evidence suggests that mixing two at-risk fungicides is also a useful resistance management tactic. The aspects that have received too little attention to draw generic conclusions about the effectiveness of fungicide mixtures as resistance management strategies are as follows: (i) the relative effect of the dose of the two mixing partners on selection for fungicide resistance, (ii) the effect of mixing on the effective life of a fungicide (the time from introduction of the fungicide mode of action to the time point where the fungicide can no longer maintain effective disease control), (iii) polygenically determined resistance, (iv) mixtures of two at-risk fungicides, (v) the emergence phase of resistance evolution and the effects of mixtures during this phase

    The term Fusion Interface is defined as a class of interface which integrally incorporates both virtual and non-virtual concepts and devices across the visual, auditory and haptic sensory modalities. A fusion interface is a multi-sensory virtually-augmented synthetic environment. A new facility has been developed within the Human Engineering Division of the Armstrong Laboratory dedicated to exploratory development of fusion-interface concepts. One of the virtual concepts to be investigated in the Fusion Interfaces for Tactical Environments facility (FITE) is the application of EEG and other physiological measures for virtual control of functions within the flight environment. FITE is a specialized flight simulator which allows efficient concept development through the use of rapid prototyping followed by direct experience of new fusion concepts. The FITE facility also supports evaluation of fusion concepts by operational fighter pilots in a high fidelity simulated air combat environment. The facility was utilized by a multi-disciplinary team composed of operational pilots, human-factors engineers, electronics engineers, computer scientists, and experimental psychologists to prototype and evaluate the first multi-sensory, virtually-augmented cockpit. The cockpit employed LCD-based head-down displays, a helmet-mounted display, three-dimensionally localized audio displays, and a haptic display. This paper will endeavor to describe the FITE facility architecture, some of the characteristics of the FITE virtual display and control devices, and the potential application of EEG and other physiological measures within the FITE facility.

    Biomineralization is an important tactic by which biological organisms produce hierarchically structured minerals with marvellous functions. Biomineralization studies typically focus on the mediation function of organic matrices on inorganic minerals, which helps scientists to design and synthesize bioinspired functional materials. However, the presence of inorganic minerals may also alter the native behaviours of organic matrices and even biological organisms. This progress report discusses the latest achievements relating to biomineralization mechanisms, the manufacturing of biomimetic materials and relevant applications in biological and biomedical fields. In particular, biomineralized vaccines and algae with improved thermostability and photosynthesis, respectively, demonstrate that biomineralization is a strategy for organism evolution via the rational design of organism-material complexes. The successful modification of biological systems using materials is based on the regulatory effect of inorganic materials on organic organisms, which is another aspect of biomineralization control. Unlike previous studies, this study integrates materials and biological science to achieve a more comprehensive view of the mechanisms and applications of biomineralization. © 2017 WILEY-VCH Verlag GmbH & Co.

    In order to provide some more scientific and practical advice and tactics for acupuncture in prevention of migraine in clinic, a computer-based information search was conducted in MEDLINE database, and the current reports of clinical trials were summarized and a comparison of Western and Chinese research designs was made. The significant role of acupuncture for prevention of migraine has not been applied in wide range in China until the present day. However, it has been paid great attention in Western countries. This situation might be related to the differences of efficacy assessment of acupuncture between China and Western countries; meanwhile, in the past traditional acupuncturists put much stress on the therapeutic approaches for acute attacks of headache but less on prevention. It is necessary for Chinese doctors to learn from research method in the West and emphasize more on acupuncture for preventing migraine and conduct high-level clinical trials as well. The author recommends that Chinese doctors should select acupuncture points mainly according to meridian syndrome differentiation and apply long term intermittent interventions.

    Full Text Available delity or prevent their defection from the relationship. These tactics include low-risk acts that render the current relationship more attractive by bestowing benefits on the woman, as well as cost-inflicting acts that render defection from the relationship risky or dangerous for her. Previous research has linked men's mate retention behavior with men's mate value (value as a current or potential partner using women's reports. The current research addresses limitations of that research using self-reports and cross-spousal reports from 107 married couples concerning their self-esteem and their esteem for their partner. The results indicate that the level of esteem that wives have for their husbands is positively associated with their perception of their husband's use of positive inducements and negatively associated with their husband's self-reported use of cost-inflicting mate retention behaviors (i.e., Direct Guarding, Intersexual Negative Inducements, and Intrasexual Negative Inducements. The level of self-esteem reported by men was negatively associated with their self-reported direct guarding behavior. Discussion explores the possibility that esteem—both self-esteem and esteem from one's partner—functions as an internal gauge of relative mate value.

    This study applied an intervention program, based on video feedback and questioning, to expert female volleyball players to improve their tactical knowledge. The sample consisted of eight female attackers (26 ± 2.6 years old) from the Spanish National Volleyball Team, who were divided into an experimental group (n = 4) and a control group (n = 4). The video feedback and questioning program applied in the study was developed over eight reflective sessions and consisted of three phases: viewing of the selected actions, self-analysis and reflection by the attacker, and joint player-coach analysis. The attackers were videotaped in an actual game and four clips (situations) of each of the attackers were chosen for each reflective session. Two of the clips showed a correct action by the attacker, and two showed an incorrect decision. Tactical knowledge was measured by problem representation with a verbal protocol. The members of the experimental group showed adaptations in long-term memory, significantly improving their tactical knowledge. With respect to conceptual content, there was an increase in the total number of conditions verbalized by the players; with respect to conceptual sophistication, there was an increase in the indication of appropriate conditions with two or more details; and finally, with respect to conceptual structure, there was an increase in the use of double or triple conceptual structures. The intervention program, based on video feedback and questioning, in addition to on-court training sessions of expert volleyball players, appears to improve the athletes' tactical knowledge. © The Author(s) 2016.

    Full Text Available In this publication, based on a comprehensive analysis of the sources, considered one of the most important tactics of the Mongols of the XIII century, known under the Turkic name "Tulgama". The name of the maneuver is derived from the Turkic verb "talamak", meaning "to surround, to wrapped up, to turn, to whirl, to twist". It is established that the maneuver "Tulgama" was a special tactic, providing coverage flank (flanks of the enemy in the rear and the application of massed archery shot in his builds. Selected three varieties under consideration tactic: right flank or left flank and steam room (double "Tulgama". The most typical was right flanks "Tulgama" when doing the nomads, covered the left wing of the enemy with its right flank. This allowed the attacking archers to fire from the most convenient position (left-forward, left, and left-back. A characteristic feature of the Mongol tactical art was a steam room (double "Tulgama" when the troops of nomads covered both enemy's flank, concluding the enemy's army in the ring, then attacked her from all four sides. A similar technique could not only shoot down from the position, but almost completely destroy the enemy troops. For the most efficient use of maneuver "Tulgama" the Mongols made increasing use of expanded mesalamines system, with a powerful thrust forward flank groups. The concentration of the shock troops on the flanks (reinforced, including by weakening the Central shelf is dramatically different from the tactics of the Mongols from the traditional tactics of the Turks, whose best part was typically the center of the combat formations. However, direct confrontation of these two approaches during the military campaigns of the XIII century demonstrated the advantages of the Mongol tactical schemes. High efficiency of reception "Tulgama" led to its continued existence in the military art of the nomads.

  5. Impact of Tactical and Strategic Weather Avoidance on Separation Assurance

    The ability to keep flights away from weather hazards while maintaining aircraft-to-aircraft separation is critically important. The Advanced Airspace Concept is an automation concept that implements a ground-based strategic conflict resolution algorithm for management of aircraft separation. The impact of dynamic and uncertain weather avoidance on this concept is investigated. A strategic weather rerouting system is integrated with the Advanced Airspace Concept, which also provides a tactical weather avoidance algorithm, in a fast time simulation of the Air Transportation System. Strategic weather rerouting is used to plan routes around weather in the 20 minute to two-hour time horizon. To address forecast uncertainty, flight routes are revised at 15 minute intervals. Tactical weather avoidance is used for short term trajectory adjustments (30 minute planning horizon) that are updated every minute to address any weather conflicts (instances where aircraft are predicted to pass through weather cells) that are left unresolved by strategic weather rerouting. The fast time simulation is used to assess the impact of tactical weather avoidance on the performance of automated conflict resolution as well as the impact of strategic weather rerouting on both conflict resolution and tactical weather avoidance. The results demonstrate that both tactical weather avoidance and strategic weather rerouting increase the algorithm complexity required to find aircraft conflict resolutions. Results also demonstrate that tactical weather avoidance is prone to higher airborne delay than strategic weather rerouting. Adding strategic weather rerouting to tactical weather avoidance reduces total airborne delays for the reported scenario by 18% and reduces the number of remaining weather violations by 13%. Finally, two features are identified that have proven important for strategic weather rerouting to realize these benefits; namely, the ability to revise reroutes and the use of maneuvers

    Energy Technology Data Exchange (ETDEWEB)

    2008-09-01

    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.

    1997-01-01

    Full Text Available The hunting tactics of male and female leopards in the southern Kalahari were analysed for prey-specific patterns. The field study was based on tracking leopard spoor in the sandy substrate of the Kalahari. Visual profiles for each type of prey were compiled for various facets of hunting. Data sets were analysed further, using Correspondence Analysis and Detrended Correspondence Analysis. The results indicate that multivariate analysis can be used to demonstrate prey-specific hunting tactics in Kalahari leopards. In using a scarce prey base, Kalahari leopards seem to be number maximisers as they are unselective of prey type, age or sex. The presence of prey-specific hunting tactics may indicate a move along a continuum towards some degree of energy maximisation.

    1994-01-01

    Hospital marketing is an intricate and complex process. Especially difficult is the transition the hospital marketer must make from designing marketing strategies to implementing those strategies. This transition usually causes the marketer to call upon a different set of skills. These skills involve managing the personnel needed to implement the designed marketing strategy. Unfortunately, little in the way of formal training is provided the marketer for developing these management skills. Therefore, the authors have comprised a series of tactical procedures designed to assist the hospital marketer to survive this transition. Using these tactics for decision-making guidelines may help to improve the management of the hospital's marketing effort.

    2014-12-01

    Full Text Available Summary: Adequate neck contour is one of the goals in facial rejuvenation. In some patients, treating the submandibular salivary gland (SMSG ensures a satisfying result. Hematoma, sialoma, and paralysis of the depressors of the lower lip may occur when the deep neck is approached. The objective of this work is to present a new tactic to prevent the aforementioned complications. Two hundred forty consecutive neck lift patients with partial resection of the SMSG were studied. The tactic consisted of placing sutures to facilitate the retraction of the platysma muscle and the accompanying marginal mandibular and cervical branches of the facial nerve during the resection of the SMSG. It also included stitches that bring the platysma muscle in contact with the remaining SMSG, sealing the dissected area. The first 25 (control subjects did not undergo the tactic; the remaining 215 (study group did. The occurrence of paralysis of the depressors of the lower lip and of hematoma and sialoma originating from the SMSG resection was observed. When comparing the control group with the study group, the rates of hematoma (8% vs 0% and sialoma (24% vs 0% were significantly higher in the former. Paralysis of the depressors of the lower lip also had a higher rate in the control group (4% vs 0.9% although this difference was not statistically significant.

    Tragesser, Sarah L; Benfield, Jacob

    2012-06-01

    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.

  9. Automatic Generation of Proof Tactics for Finite-Valued Logics

    Directory of Open Access Journals (Sweden)

    João Marcos

    2010-03-01

    Full Text Available A number of flexible tactic-based logical frameworks are nowadays available that can implement a wide range of mathematical theories using a common higher-order metalanguage. Used as proof assistants, one of the advantages of such powerful systems resides in their responsiveness to extensibility of their reasoning capabilities, being designed over rule-based programming languages that allow the user to build her own `programs to construct proofs' - the so-called proof tactics. The present contribution discusses the implementation of an algorithm that generates sound and complete tableau systems for a very inclusive class of sufficiently expressive finite-valued propositional logics, and then illustrates some of the challenges and difficulties related to the algorithmic formation of automated theorem proving tactics for such logics. The procedure on whose implementation we will report is based on a generalized notion of analyticity of proof systems that is intended to guarantee termination of the corresponding automated tactics on what concerns theoremhood in our targeted logics.

  2. Tactic-specific differences in seminal fluid influence sperm performance.

    Science.gov (United States)

    Locatello, Lisa; Poli, Federica; Rasotto, Maria B

    2013-03-22

    Seminal fluid often makes up a large part of an ejaculate, yet most empirical and theoretical studies on sperm competition have focused on how sperm characteristics (number and quality) affect fertilization success. However, seminal fluid influences own sperm performance and may potentially influence the outcome of sperm competition, by also affecting that of rivals. As a consequence males may be expected to allocate their investment in both sperm and seminal fluid in relation to the potential level of competition. Grass goby (Zosterisessor ophiocephalus) is an external fertilizer with guard-sneaker mating tactics, where sperm competition risk varies according to the tactic adopted. Here, we experimentally manipulated grass goby ejaculates by separately combining sperm and seminal fluid from territorial and sneaker males. While sperm of sneaker and territorial males did not differ in their performance when they interacted with their own seminal fluid only, sperm of sneakers increased their velocity and fertilization rate in the presence of territorial males' seminal fluid. By contrast, sneaker males' seminal fluid had a detrimental effect on the performance of territorial males' sperm. Sperm velocity was unaffected by the seminal fluid of males employing the same tactic, suggesting that seminal fluid's effect on rival-tactic sperm is not based on a self/non-self recognition mechanism. Our findings show that cross interactions of sperm and seminal fluid may influence the fertilization success of competing ejaculates with males investing in both sperm and seminal fluid in response to sperm competition risk.

    Changing lifestyles, decreasing physical activity, which is increasing the number of degenerative joint diseases of various etiology, and certain dental procedures are increasing the number of patients complaining of pain in their temporomandibular joints. The aim of the study was to assess the benefits of comprehensive physiotherapy sessions in order to decrease the number of temporomandibular joint problems, thereby improving the patient's quality of life. An examination by a dentist determined each patient's treatment plan, which consisted of a medical exam, physical therapy and education. Each form of treatment was applied 10 times at intervals of 7-14 days. The main goal of the therapeutic physical education was to redress the muscle imbalance in the mandibular joint. This was achieved by restoring balance between the masticatory muscles, along with releasing the spastic shrouds found in the masticatory muscles. The aim of education was to teach the patient exercises focused on the temporomandibular joint and masticatory muscles. The intensity of the exercises and their composition were individually adjusted and adapted to their current state. Physical therapy consisted of the application of pulsed magnetic therapy, laser therapy, and non-invasive positive thermotherapy. The above procedure was conducted on a therapeutic group of 24 patients (3 men and 20 women). In the course of therapy, there were no complications, and all patients adhered to the prescribed regime. None reported any side effects. The mean treatment duration was 123 +/- 66 days. The outcome of the therapy was evaluated as described in the methodology, the degree of pain affecting the joint, and the opening ability of the mouth. In both parameters, there was a significant decline in patient pain. In a study devoted to tactics of rehabilitation treatment for temporomandibular joint disorders, the need for comprehensive long-term therapy, involving education, and learning proper chewing habits

    2015-02-01

    Full Text Available Background: The potential of the World Wide Web (‘the Web’ as a tool for information retrieval in higher education is beyond question. Harnessing this potential, however, remains a challenge, particularly in the context of developing countries, where students are drawn from diverse socio-economic, educational and technological backgrounds. Objectives: The purpose of this study is to identify the Web search tactics used by postgraduate students in order to address the weaknesses of undergraduate students with regard to their Web searching tactics. This article forms part of a wider study into postgraduate students’ information retrieval strategies at the University of KwaZulu-Natal, Pietermaritzburg campus, South Africa. Method: The study utilised the mixed methods approach, employing both questionnaires (Phase 1 and structured interviews (Phase 2, and was largely underpinned by Bates’s model of information search tactics. This article reports and reflects on the findings of Phase 1, which focused on identifying the Web search tactics employed by postgraduate students. Results: Findings indicated a preference for lower-level Web search tactics, despite respondents largely self-reporting as intermediate or expert users. Moreover, the majority of respondents gained their knowledge on Web searching through experience and only a quarter of respondents have been given formal training on Web searching. Conclusion: In addition to contributing to theory, it is envisaged that this article will contribute to practice by informing the design of undergraduate training interventions to proactively address the information retrieval challenges faced by novice users. Subsequent papers will report on Phase 2 of the study.

To do so we provide an appraisal of the grips concept and his consequences in the Olympic sport judo from a biomechanics perspective, we will try to deeper both the concept and the function of grips and define the potential application of some throws without grips. Broadening this situation we try to underline some specific throwing situation in which grips are or not at all applied or applied in non conventional way. We describe at first the problem from the theoretical point of view. And as second point we try to find practical application, original or already developed in high level competitions. The provocative words Judo without grips or throw without grips are connected to the limit application of some biomechanical tricks, ground...

  12. Male Megacyllene robiniae (Coleoptera: Cerambycidae) use multiple tactics when aggressively competing for mates.

    Ray, Ann M; Ginzel, Matthew D; Hanks, Lawrence M

    2009-04-01

    Adult male Megacyllene robiniae (Förster) (Coleoptera: Cerambycidae) that are paired with a female often are challenged by conspecific males that attempt to displace them. In staged laboratory bouts, challenging males used seven distinct tactics to displace defending males, including wedging their head between the defender and the female (termed wedging), straddling the mated pair and pulling the defender off (prying), pulling it with the mandibles, batting it with the antennae, or pushing, biting, or kicking the defender. Individual challengers attempted as many as six different tactics in a single bout, repeating certain tactics multiple times. They often attempted tactics that were not very effective. For example, prying was one of the most common attempted tactics but was rarely effective. However, few challengers attempted to push defenders off the female, even though that tactic often was effective. Challengers apparently were influenced by context in their choice of particular tactics. For example, males that approached the mated pair from the side were likely to use wedging, whereas those approaching head on were more likely to bat with the antennae. Choice of tactic apparently was not influenced by absolute size of challengers, nor was it strongly influenced by relative size of defenders. However, the effectiveness of tactics varied significantly with relative body size: larger challengers were most successful when prying or pushing, while smaller challengers were most successful when biting and kicking. By using different tactics, relatively small males were as adept as larger males at displacing rivals.

    Cryogenic refrigerators represent a significant enabling technology for Earth and Space science enterprises. Many of the space instruments require cryogenic refrigeration to enable the use of advanced detectors to explore a wide range of phenomena from space. RICOR refrigerators involved in various space missions are overviewed in this paper, starting in 1994 with "Clementine" Moon mission, till the latest ExoMars mission launched in 2016. RICOR tactical rotary refrigerators have been incorporated in many space instruments, after passing qualification, life time, thermal management testing and flight acceptance. The tactical to space customization framework includes an extensive characterization and qualification test program to validate reliability, the design of thermal interfacing with a detector, vibration export control, efficient heat dissipation in a vacuum environment, robustness, mounting design, compliance with outgassing requirements and strict performance screening. Current RICOR development is focused on dedicated ultra-long-life, highly reliable, space cryogenic refrigerator based on a Pulse Tube design

It argues that 2013 marked a significant evolution in Boko Haram’s tactics, with a series of kidnappings, in which one of the main features was the instrumental use of women. This was in response to corresponding tactics by the Nigerian security forces. Additionally the analysis provides evidence of a shift by Boko Haram to include women in its operations, in response to increased pressure on male operatives. It also considers the gendered rationale for instrumentalizing women within the framework of Boko Haram’s ideology and culture, arguing for a greater appreciation of how gender factors in the group’s violence.'

    2014-03-01

    To ensure effective biomass feedstock provision for large-scale biofuel production, an integrated biomass supply chain optimization model was developed to minimize annual biomass-ethanol production costs by optimizing both strategic and tactical planning decisions simultaneously. The mixed integer linear programming model optimizes the activities range from biomass harvesting, packing, in-field transportation, stacking, transportation, preprocessing, and storage, to ethanol production and distribution. The numbers, locations, and capacities of facilities as well as biomass and ethanol distribution patterns are key strategic decisions; while biomass production, delivery, and operating schedules and inventory monitoring are key tactical decisions. The model was implemented to study Miscanthus-ethanol supply chain in Illinois. The base case results showed unit Miscanthus-ethanol production costs were $0.72L(-1) of ethanol. Biorefinery related costs accounts for 62% of the total costs, followed by biomass procurement costs. Sensitivity analysis showed that a 50% reduction in biomass yield would increase unit production costs by 11%.

    2017-10-01

    Full Text Available Aim: to determine the efficiency of the cyclist in various tactical options. Material: In the experiments participated athletes (n = 6 of high qualification (mean age - 19.8 ± 1.3 years, mean weight - 71.4 ± 3.5 kg. As a model of the individual pursuit race at 4 km, a five-minute pedaling on the bicycle ergometer was used. Series of loads was set on the modernized mechanical bicycle ergometer “Monark” . The five-minute bicycle ergometer test is similar to the individual pursuit race at 4 km: according to the time of the exercise; on the frequency of pedaling (110-120 rpm; on the frequency of heartbeats. Results: Tactical variants in the pursuit race at 4 km are considered. The total work in a free test was on average 106.38 ± 3.57 kJ. The operating energy consumption is on average for 379.0±16.1 kJ. The operating efficiency (economy of the exercise attained on average for 28.0 ± 0.75%. This corresponds to the effectiveness of aerobic work of moderate power. The ratio of aerobic and anaerobic contributions to the provision of work was 77.3 and 22.7%. The smallest work was done in a test with step-increasing power. The athletes performed the closest work to the given job in the test with a variable (±15% operating mode. The shortfall in it was on average for 0.46%. The absence of reliable differences in the economics of the work did not allow us to identify a rational variant of power distribution for an exercise lasting 5 minutes. Conclusions: Tactical options in the pursuit race for 4 km depend on the features of the power systems of the rider. When optimizing tactics, it is necessary to select an individually optimal variant of the distribution of forces at a distance.

    The purpose of this study was to define the technical and tactical profiles of official youth taekwondo competitions played under the most recent rules of the International Taekwondo Federation. Tactical actions (i.e., attack, defense, and block), technical executions (from 1- to 4-point scores), kicking legs (i.e., front/rear and right/left), and overall technical effectiveness were investigated in relation to match outcome of semifinal and final competitions (n = 50) of youth (aged 13-14 years) black belt athletes during the Italian Taekwondo Cadet Championship. Differences (p technical exchanges showed differences (p technical executions. Winners resulted more efficient (p technical and tactical variables. In general, these findings showed that Cadets tend to adopt an offensive strategy. In considering that the adoption of the new electronic system requires athletes to execute correct technical actions to have a score assigned, coaches should emphasize the effectiveness of scoring techniques and help athletes to effectively improve their defense and counterattack capabilities.

    The Mars Exploration Rover Mission (MER) includes the twin rovers, Spirit and Opportunity, which have been performing geological research and surface exploration since early 2004. The rovers' durability well beyond their original prime mission (90 sols or Martian days) has allowed them to be a valuable platform for scientific research for well over 2000 sols, but as a by-product it has produced new challenges in providing efficient and cost-effective tactical operational planning. An early stage process adaptation was the move to distributed operations as mission scientists returned to their places of work in the summer of 2004, but they would still came together via teleconference and connected software to plan rover activities a few times a week. This distributed model has worked well since, but it requires the purchase, operation, and maintenance of a dedicated infrastructure at the Jet Propulsion Laboratory. This server infrastructure is costly to operate and the periodic nature of its usage (typically heavy usage for 8 hours every 2 days) has made moving to a cloud based tactical infrastructure an extremely tempting proposition. In this paper we will review both past and current implementations of the tactical planning application focusing on remote plan saving and discuss the unique challenges present with long-latency, distributed operations. We then detail the motivations behind our move to cloud based computing services and as well as our system design and implementation. We will discuss security and reliability concerns and how they were addressed

    2016-01-01

    One of the most strategic and the most significant decisions in supply chain management is reconfiguration of the structure and design of the supply chain network. In this paper, a closed loop supply chain network design model is presented to select the best tactical and strategic decision levels simultaneously considering the appropriate transportation mode in activated links. The strategic decisions are made for a long term; thus, it is more satisfactory and more appropriate when the decision variables are considered uncertain and fuzzy, because it is more flexible and near to the real world. This paper is the first research which considers fuzzy decision variables in the supply chain network design model. Moreover, in this study a new fuzzy optimization approach is proposed to solve a supply chain network design problem with fuzzy tactical decision variables. Finally, the proposed approach and model are verified using several numerical examples. The comparison of the results with other existing approaches confirms efficiency of the proposed approach. Moreover the results confirms that by considering the vagueness of tactical decisions some properties of the supply chain network will be improved.

  7. A tactical asset allocation strategy that exploits variations in VIX

    Directory of Open Access Journals (Sweden)

    Richard Cloutier

    2017-03-01

    Full Text Available Buy and hold strategies make staying disciplined difficult for investors, especially given the variability of returns for different asset classes/strategies during divergent market conditions. Market timing strategies, on the other hand, present significant theoretical benefits, but in reality these benefits are difficult to obtain. Tactical asset allocation, where limited deviations from the strategic allocation are allowed permits the portfolio manager to take advantage of market conditions fits between these two extremes. The authors correlate daily returns for each of eighteen separate asset classes typically used in diversified institutional portfolios and daily closing values of the VIX (the ticker symbol for the Chicago Board Options Exchange Volatility Index. This information is used to select those classes whose returns are most responsive to the level of the VIX. Portfolio allocations for eight selected asset classes are revised depending on the level of the VIX at the daily close of the market. The portfolio is rebalanced on the business day following the day the VIX hits the trigger value. The VIX tactical allocation overlay yields an increase in return over the buy and hold portfolio of approximately 38 basis points. The authors conclude that the tactical asset allocation strategy based on the level of VIX provides a higher return than the neutral buy and hold allocation with a higher Sharpe ratio and lower volatility.

  10. Stirring, charging, and picking: hunting tactics of potamotrygonid rays in the upper Paraná River

    Directory of Open Access Journals (Sweden)

    Domingos Garrone-Neto

    Full Text Available Hunting tactics of potamotrygonid freshwater rays remain unreported under natural conditions. Three main foraging tactics of Potamotrygon falkneri and P. motoro are described here based on underwater observations in the upper Paraná River. Both species displayed similar behaviors. The most common tactic was to undulate the disc margins close to, or on, the bottom and thus stirring the substrate and uncovering hidden preys. Another tactic was to charge upon prey concentrated in the shallows. The least common tactic was to pick out prey adhered to the substrate. The first tactic is widespread in several species of marine rays in the Dasyatidae, whereas the remainder (especially picking up prey on substrata above water surface may be restricted to the Potamotrygonidae.

    2010-12-13

    The synthesis of a family of polymer stars with arms of varied tacticities is discussed. The effect of polymer tacticity on the physical properties of these polymer stars is presented. Dipentaerythritol cores support six poly(lactic acid) (PLA) arms. Lewis acidic tin and aluminum catalysts control the polymerization to afford polymer stars of variable tacticity. The analysis of these polymers by NMR spectroscopy, thermogravimetric analysis, powder X-ray diffraction, and differential scanning calorimetry reveals the effects of tacticity control on the physical properties of the polymer stars. Preliminary decomposition studies suggest that the biodegradation profile of a polymer star may also be tuned by stereochemical control. This is the first systematic altering of tacticity in PLA polymer stars, showing that polymer tacticity can have a great impact on star properties.

    Kamada, Masafumi; Fuchigami, Katsuyoshi

    2010-08-01

    This study examines how children's social power cognitions about themselves and the collective efficacy of their classrooms affect their selection and use of influence tactics toward their classmates. The effect of daily usage of influence tactics by children on agents' perception of social power is also examined. The results of linear regression analysis indicate that children who see themselves as friendly holders of power deriving from the perception of affable friendships use both collaborative and coercive influence tactics. While the use of collaborative tactics encourages agents' friendly social power cognition, the use of coercive tactics only reinforces their coercive power cognition. In addition, it is suggested that the effect of social power over agents' use of influence tactics is moderated by the collective efficacy of their classroom.

    1995-01-01

    The joint University of Rochester/Rochester Institute of Technology `Center for Electronic Imaging Systems' (CEIS) is designed to focus on research problems of interest to industrial sponsors. A particular feature of the research is that it is organized in the `triplet' mode: each project includes a faculty researcher, an industrial partner, and a doctoral or postdoctoral fellow. Compression of tactical images for transmission over an rf link is an example of this type of research project which is being worked on in collaboration with one of the CEIS sponsors, Harris Corporation/Rf communications. The Harris Digital Video Imagery Transmission System (DVITS) is designed to fulfill the need to transmit secure imagery between unwired locations at real-time rates. DVITS specializes in transmission systems for users who rely on hf equipment operating at the low end of the frequency spectrum. However, the inherently low bandwidth of hf combined with transmission characteristics such as fading and dropout severely restrict the effective throughput. The problem is posed as one of maximizing the probability of reception of the most significant information in an m x n pixel image in the shortest possible time. Various design strategies combining image segmentation, compression, and error correction are evaluated using a realistic model for the communication channel. A recommended strategy is developed and a test method using a variety of test images is described. The methodology established here can be employed for other image transmission designs.

    Pressure suit mobility joints are for use in interconnecting adjacent segments of an hermetically sealed spacesuit in which low torques, low leakage and a high degree of reliability are required. Each of the joints is a special purpose joint characterized by substantially constant volume and low torque characteristics and includes linkages which restrain the joint from longitudinal distension and includes a flexible, substantially impermeable diaphragm of tubular configuration spanning the distance between pivotally supported annuli. The diaphragms of selected joints include rolling convolutions for balancing the joints, while various joints include wedge-shaped sections which enhance the range of motion for the joints.

  1. Joint Forward Operating Base Elements of Command and Control

    Summers, William C.

    2002-01-01

    Since the 1986 Goldwater-Nichols Act directed the Chairman of the Joint Chiefs of Staff to develop doctrine for the joint employment of the armed forces, tactics, techniques, and procedures have evolved at different rates depending on the competency. Whereas the command of joint air forces is well prescribed within the structure of the air operations center and its associated leadership, command of air assets at a joint forward operating base lacks guidance. Today, the United States prosecutes an air war over Afghanistan from bases in Uzbekistan, Pakistan, and Afghanistan. Elements of the United States Army, Air Force, and Marines combine at these geographically minute locations, each bringing a certain complement of support and command and control. Evidence from operations during the 1999 air war for Kosovo at Tirana Rinas Airport in Albania suggests that when these service elements meet at the airfield for the first time, there are problems associated with local procedure. At best, time is wasted creating local joint systems to overcome the difficulties. At worst, safety and mission accomplishment are jeopardized. This thesis will address the need to develop doctrine and a jointly integrated organization to support the command and control function at a forward operating base.

    de Róiste, Aine

    2004-12-01

    This article provides a synopsis of a series of studies exploring the effects of TAC-TIC (Touching And Caressing-Tender In Caring) therapy with premature infants. Study 1 looked at the short and long-term effects and found enhanced mental development in the stroked infants at 15 months. In study 2 the physiological effects of an abbreviated version of TAC-TIC with high-risk ventilated infants were examined and it was concluded that TAC-TIC exerted no harm to these vulnerable infants. The behavioural reactions of a sample of premature and low birthweight infants to TAC-TIC and parental responses to administering it were explored in study 3. The infants were found to respond predominantly with arm and leg movements to TAC-TIC while fathers and mothers reported enjoying performing TAC-TIC and elicited a similar pattern and frequency of behavioural reactions. In study 4 the question of whether TAC-TIC benefits preterm infant learning and/or sucking behaviour was investigated. The conclusion reached was that TAC-TIC may potentially benefit cognitive performance within the neonatal period and that this may be an early indicator of long-term cognitive gains reported by previous studies. Using a matched subjects design, study 5 explored the impact of TAC-TIC upon the digestive system by analysing gastric aspirates before and after TAC-TIC and a control period of time. It was concluded that TAC-TIC appeared to induce a more suitable stomach environment for digestion.

    2009-04-01

    Subsurface coal fires destroy millions of tons of coal each year, have an immense impact to the ecological surrounding and threaten further coal reservoirs. Due to enormous dimensions a coal seam fire can develop, high operational expenses are needed. As part of the Sino-German coal fire research initiative "Innovative technologies for exploration, extinction and monitoring of coal fires in Northern China" the research team of University of Wuppertal (BUW) focuses on fire extinction strategies and tactics as well as aspects of environmental and health safety. Besides the choice and the correct application of different extinction techniques further factors are essential for the successful extinction. Appropriate tactics, well trained and protected personnel and the choice of the best fitting extinguishing agents are necessary for the successful extinction of a coal seam fire. The chosen strategy for an extinction campaign is generally determined by urgency and importance. It may depend on national objectives and concepts of coal conservation, on environmental protection (e.g. commitment to green house gases (GHG) reductions), national funding and resources for fire fighting (e.g. personnel, infrastructure, vehicles, water pipelines); and computer-aided models and simulations of coal fire development from self ignition to extinction. In order to devise an optimal fire fighting strategy, "aims of protection" have to be defined in a first step. These may be: - directly affected coal seams; - neighboring seams and coalfields; - GHG emissions into the atmosphere; - Returns on investments (costs of fire fighting compared to value of saved coal). In a further step, it is imperative to decide whether the budget shall define the results, or the results define the budget; i.e. whether there are fixed objectives for the mission that will dictate the overall budget, or whether the limited resources available shall set the scope within which the best possible results shall be

  4. Smarter Instruments, Smarter Archives: Machine Learning for Tactical Science

    Thompson, D. R.; Kiran, R.; Allwood, A.; Altinok, A.; Estlin, T.; Flannery, D.

    2014-12-01

    There has been a growing interest by Earth and Planetary Sciences in machine learning, visualization and cyberinfrastructure to interpret ever-increasing volumes of instrument data. Such tools are commonly used to analyze archival datasets, but they can also play a valuable real-time role during missions. Here we discuss ways that machine learning can benefit tactical science decisions during Earth and Planetary Exploration. Machine learning's potential begins at the instrument itself. Smart instruments endowed with pattern recognition can immediately recognize science features of interest. This allows robotic explorers to optimize their limited communications bandwidth, triaging science products and prioritizing the most relevant data. Smart instruments can also target their data collection on the fly, using principles of experimental design to reduce redundancy and generally improve sampling efficiency for time-limited operations. Moreover, smart instruments can respond immediately to transient or unexpected phenomena. Examples include detections of cometary plumes, terrestrial floods, or volcanism. We show recent examples of smart instruments from 2014 tests including: aircraft and spacecraft remote sensing instruments that recognize cloud contamination, field tests of a "smart camera" for robotic surface geology, and adaptive data collection by X-Ray fluorescence spectrometers. Machine learning can also assist human operators when tactical decision making is required. Terrestrial scenarios include airborne remote sensing, where the decision to re-fly a transect must be made immediately. Planetary scenarios include deep space encounters or planetary surface exploration, where the number of command cycles is limited and operators make rapid daily decisions about where next to collect measurements. Visualization and modeling can reveal trends, clusters, and outliers in new data. This can help operators recognize instrument artifacts or spot anomalies in real time

    2013-01-01

    The purpose of this study was to assess the appropriateness of offensive tactical decision-making of Arab basketball players, and to determine if there are differences in the appropriateness of offensive tactical decision-making within the various disability classifications of Arab basketball players. A twenty-question survey was formulated to assess decision-making in offensive tactical situations in wheelchair basketball players. Participants in the present study were 108 athletes from 10 Arab national teams participating in wheelchair basketball. The mean offensive tactical thinking level of wheelchair basketball players in the 20 different situations in the Arab countries ranged between 1.38-2.84, and the standard deviations for these 20 means ranged from 0.41 to 0.90. The total mean of all tactical situations was 2.33, which is moderate thinking level. The influence of the disability classification on the offensive tactical thinking of wheelchair basketball players was addressed by examining the data via a one-way ANOVA. The ANOVA revealed no significant differences among disability classifications/categories in tactical thinking (F(3, 104)=1.12, p=0.34). This study represents the first attempt to identify why Arab nations have not consistently qualified for the Paralympics or World Championships. These findings indicate that the moderate offensive tactical thinking level of wheelchair basketball players on Arab national teams may be part of the reason that performances of these teams have not been as strong as they would like.

    2015-01-01

    Two core elements for the coordination of different actions in sport are tactical information and knowledge about tactical situations. The current study describes two experiments to learn about the memory structure and the cognitive processing of tactical information. Experiment 1 investigated the storage and structuring of team-specific tactics in humans' long-term memory with regard to different expertise levels. Experiment 2 investigated tactical decision-making skills and the corresponding gaze behavior, in presenting participants the identical match situations in a reaction time task. The results showed that more experienced soccer players, in contrast to less experienced soccer players, possess a functionally organized cognitive representation of team-specific tactics in soccer. Moreover, the more experienced soccer players reacted faster in tactical decisions, because they needed less fixations of similar duration as compared to less experienced soccer players. Combined, these experiments offer evidence that a functionally organized memory structure leads to a reaction time and a perceptual advantage in tactical decision-making in soccer. The discussion emphasizes theoretical and applied implications of the current results of the study.

    2017-01-01

    Physician interest in tactical medicine as an area of professional practice has grown significantly over the past decade. The prevalence of physician involvement in terms of medical oversight and operational support of civilian tactical medicine has experienced tremendous growth during this timeframe. Factors contributing to this trend are multifactorial and include enhanced law enforcement agency understanding of the role of the tactical physician, support for the engagement of qualified medical oversight, increasing numbers of physicians formally trained in tactical medicine, and the ongoing escalation of intentional mass-casualty incidents worldwide. Continued vigilance for the sustenance of adequate and appropriate graduate medical education resources for physicians seeking training in the comprehensive aspects of tactical medicine is essential to ensure continued advancement of the quality of casualty care in the civilian high-threat environment.

  6. The role of leader influence tactics and safety climate in engaging employees' safety participation.

    Clarke, Sharon; Ward, Katie

    2006-10-01

    This study examines the effect of leader influence tactics on employee safety participation in a U.K.-based manufacturing organization, examining the role of safety climate as a mediator. Structural equation modeling showed that leader influence tactics associated with a transformational leadership style had significant relationships with safety participation that were partially mediated by the safety climate (consultation) or fully mediated by the safety climate (inspirational appeals). In addition, leader influence tactics associated with a transactional leadership style had significant relationships with safety participation: rational persuasion (partially mediated by safety climate) and coalition tactics (direct effect). Thus, leaders may encourage safety participation using a combination of influence tactics, based on rational arguments, involvement in decision making, and generating enthusiasm for safety. The influence of building trust in managers is discussed as an underlying mechanism in this relationship. Practical implications are highlighted, including the design of leadership development programs, which may be particularly suited to high-reliability organizations.

  7. Friendship as a Relationship Infiltration Tactic during Human Mate Poaching

    Directory of Open Access Journals (Sweden)

    Justin K. Mogilski

    2013-10-01

    Full Text Available Previous research has characterized human mate poaching as a prevalent alternative mating strategy that entails risks and costs typically not present during general romantic courtship and attraction. This study is the first to experimentally investigate friendship between a poacher and his/her target as a risk mitigation tactic. Participants (N = 382 read a vignette that differed by whether the poacher was male/female and whether the poacher and poached were friends/acquaintances. Participants assessed the likelihood of the poacher being successful and incurring costs. They also rated the poacher and poached on several personality and mate characteristics. Results revealed that friendship increased the perceived likelihood of success of a mate poaching attempt and decreased the perceived likelihood of several risks typically associated with mate poaching. However, friend-poachers were rated less favorably than acquaintance-poachers across measures of warmth, nurturance, and friendliness. These findings are interpreted using an evolutionary perspective. This study complements and builds upon previous findings and is the first experimental investigation of tactics poachers may use to mitigate risks inherent in mate poaching.

    1990-01-01

    A research program investigating the use of Artificial Intelligence (AI) techniques to aid in the development of a Tactical Decision Generator (TDG) for Within Visual Range (WVR) air combat engagements is discussed. The application of AI programming and problem solving methods in the development and implementation of the Computerized Logic For Air-to-Air Warfare Simulations (CLAWS), a second generation TDG, is presented. The Knowledge-Based Systems used by CLAWS to aid in the tactical decision-making process are outlined in detail, and the results of tests to evaluate the performance of CLAWS versus a baseline TDG developed in FORTRAN to run in real-time in the Langley Differential Maneuvering Simulator (DMS), are presented. To date, these test results have shown significant performance gains with respect to the TDG baseline in one-versus-one air combat engagements, and the AI-based TDG software has proven to be much easier to modify and maintain than the baseline FORTRAN TDG programs. Alternate computing environments and programming approaches, including the use of parallel algorithms and heterogeneous computer networks are discussed, and the design and performance of a prototype concurrent TDG system are presented.

  9. An ontology for tactical behaviors derived from verb frames

    Science.gov (United States)

    Esterline, Albert C., Jr.; BouSaba, Chafic W.

    2008-04-01

    We present an initial ontology for tactical behaviors conducted by unmanned ground vehicles (UGVs). We focus on activities, which are the denotations of verbs, notably 'move' but also 'look (for)' and several others. These take collective subjects, allowing activities to be attributed to units at various hierarchical levels. The semantics of verbs must consider the denotations of their grammatical complements; that is, we must consider entire verb frames. The thematic relations of the noun-phrase complements are critical, but prepositions also play an important role. FrameNet is an online lexical database of frames derived from text corpora. Our other major resource is Levin's classification of verbs according to how changes in their frames affect their meanings. Although natural languages have a large variety of words for aspects of tactical behaviors, there is motivation to get by with as few basic verbs as possible. A variety of meanings can often be associated with a verb by altering its frame, and we can impose co-reference constraints on combinations of frames to generate structures denoting more complex activities. A simple grammar is developed for the verbs of interest. Protege-Frames ontologies include classes that inherit from linguistically inspired classes but capture domain-specific notions.

    The fundamental tactical principles of the game of soccer represent a set of action rules that guide behaviours related to the management of game space. The aim of this study was to compare the performance of fundamental offensive and defensive tactical principles among youth soccer players from 12 to 17 years old. The sample consisted of 3689 tactical actions performed by 48 soccer players in three age categories: under 13 (U-13), under 15 (U-15), and under 17 (U-17). Tactical performance was measured using the System of Tactical Assessment in Soccer (FUT-SAT). The Kruskal Wallis, Mann-Whitney U, Friedman, Wilcoxon, and Cohen's Kappa tests were used in the study analysis. The results showed that the principles of "offensive coverage" (p = 0.01) and "concentration" (p = 0.04) were performed more frequently by the U-17 players than the U-13 players. The tactical principles "width and length" (p < 0.05) and "defensive unit" (p < 0.05) were executed more frequently by younger soccer players. It can be concluded that the frequency with which fundamental tactical principles are performed varies between the gaming categories, which implies that there is valuation of defensive security and a progressive increase in "offensive coverage" caused by increased confidence and security in offensive actions.

    Research on racket sports has traditionally focused on expert players and has treated energy expenditure and tactics as independent factors. These prior studies could not assess how energy expenditure and tactics changed as a function of experience and skill. Here, the specific relationship between playing tactics and energy expenditure in badminton were assessed. Participants were classified into five stages of badminton experience on the basis of conative criteria: structural (physical abilities), technical (technical skills), and functional (tactics). The physical activity of 99 players (47 beginners, 15 intermediates, 30 advanced, and 7 experts) was measured using a three-axis accelerometer during a badminton set (21 points, no extra scoring). The results showed that physical activity (counts/sec.) ranged between about 115 (Stage 1) and 155 (Stage 5), and differed significantly across the conative stages. For Stages 2 and 4, defined by an increase in use of tactics, physical activity increased substantially. For Stage 3, defined by a decrease in use of tactics, physical activity decreased significantly. Thus, tactically-oriented play appears to be closely related to physical activity.

  13. Big data and tactical analysis in elite soccer: future challenges and opportunities for sports science.

    Science.gov (United States)

    Rein, Robert; Memmert, Daniel

    2016-01-01

    Until recently tactical analysis in elite soccer were based on observational data using variables which discard most contextual information. Analyses of team tactics require however detailed data from various sources including technical skill, individual physiological performance, and team formations among others to represent the complex processes underlying team tactical behavior. Accordingly, little is known about how these different factors influence team tactical behavior in elite soccer. In parts, this has also been due to the lack of available data. Increasingly however, detailed game logs obtained through next-generation tracking technologies in addition to physiological training data collected through novel miniature sensor technologies have become available for research. This leads however to the opposite problem where the shear amount of data becomes an obstacle in itself as methodological guidelines as well as theoretical modelling of tactical decision making in team sports is lacking. The present paper discusses how big data and modern machine learning technologies may help to address these issues and aid in developing a theoretical model for tactical decision making in team sports. As experience from medical applications show, significant organizational obstacles regarding data governance and access to technologies must be overcome first. The present work discusses these issues with respect to tactical analyses in elite soccer and propose a technological stack which aims to introduce big data technologies into elite soccer research. The proposed approach could also serve as a guideline for other sports science domains as increasing data size is becoming a wide-spread phenomenon.

  14. Brain Transcriptional Profiles of Male Alternative Reproductive Tactics and Females in Bluegill Sunfish

    Partridge, Charlyn G.; MacManes, Matthew D.; Knapp, Rosemary; Neff, Bryan D.

    2016-01-01

    Bluegill sunfish (Lepomis macrochirus) are one of the classic systems for studying male alternative reproductive tactics (ARTs) in teleost fishes. In this species, there are two distinct life histories: parental and cuckolder, encompassing three reproductive tactics, parental, satellite, and sneaker. The parental life history is fixed, whereas individuals who enter the cuckolder life history transition from sneaker to satellite tactic as they grow. For this study, we used RNAseq to characterize the brain transcriptome of the three male tactics and females during spawning to identify gene ontology (GO) categories and potential candidate genes associated with each tactic. We found that sneaker males had higher levels of gene expression differentiation compared to the other two male tactics. Sneaker males also had higher expression in ionotropic glutamate receptor genes, specifically AMPA receptors, compared to other males, which may be important for increased spatial working memory while attempting to cuckold parental males at their nests. Larger differences in gene expression also occurred among male tactics than between males and females. We found significant expression differences in several candidate genes that were previously identified in other species with ARTs and suggest a previously undescribed role for cAMP-responsive element modulator (crem) in influencing parental male behaviors during spawning.

  15. Effects of lake warming on behavioural thermoregulatory tactics in a cold-water stenothermic fish.

    Directory of Open Access Journals (Sweden)

    Katerine Goyer

    Full Text Available Despite some evidence of within-population phenotypic variation in fish thermal behaviour, the occurrence of alternative tactics of this behaviour is rarely explicitly considered when studying natural populations. Brook charr provide an example of within-population variability in behavioural thermoregulation as revealed by a recent study on a lacustrine population of this species. The objectives of the present study were (i to determine the influence of natural variability in the lake's thermal profiles on the expression of thermoregulatory tactics, and (ii to determine the vertical and horizontal movements of individuals at different periods of the day to better understand the spatio-temporal behaviour associated with each thermoregulatory tactic. During summer 2010, 30 adult brook charr were equipped with thermo-sensitive radio transmitters to monitor their selected temperatures and daily movements. These individuals exhibited the same four behavioural thermoregulatory tactics observed in 2003 and 2005, but the expression of two of these was weaker in 2010. This result was associated with lake warming, which constrained the expression of two thermoregulatory tactics: brook charr significantly decreased their selected temperatures and daily movements when the mean daily epilimnion temperature was above 22.4°C. This study shows for the first time that the expression of behavioural thermoregulatory tactics is related to the lake's thermal regime and that the tactics are plastic through time.

    To describe local implementation tactics used by the 25 Project Diabetes communities and partnering organizations to help patients who are disproportionately affected by diabetes. Care was delivered in 25 communities within 17 states at federally qualified health centers, community pharmacies, free clinics, employer work sites, medical clinics, physician offices, and other settings. In addition to pharmacists, practices included physicians, nurse practitioners, dietitians, physician assistants, social workers, behavioral therapists, and other types of health professionals. Insurance status and the predominant ethnicity of patients differed between communities. Each community had at least one community champion responsible for leading local implementation who was supported by an American Pharmacists Association Foundation community coordinator and Foundation staff. The key innovations within each of the 25 communities were the integration of pharmacists on diabetes care teams, use of the Patient Self-Management Credential for Diabetes at baseline, and collection of a standardized minimum dataset. Communities deployed other practice innovations to support the care model, including group education classes, grocery store tours, joint provider visits, and provision of patient incentives. The specific components of each community's implementation and innovation were aggregated via postproject surveys. Clinical and process measures were also collected and are published separately. Each community is characterized based on the people involved and the care delivered. Aspects of the communities described include health care provider teams, population characteristics, practice settings, care components, data collection methods, incentives provided, and self-reported service sustainability. Pharmacists can be integrated successfully into a diverse array of practice settings and teams to help a wide variety of patients through the provision of team-based, patient-centered care

    Results of a prefeasibility study of electromagnetic launchers for a tactical applications demonstrator are described. The object of this work was to study the power system requirements for a 12 MJ (kinetic energy) railgun system which would be used to demonstrate the accuracy and lethality of hypervelocity projectiles (up to 3.5 km/s) fired from a railgun. Theoretical work is presented as a basis for scoping calculations to determine the required pulse energies for a railgun power system, as a function of the required projectile peak-to-mean-acceleration ratio; this shows that the introduction of a requirement for a low peak-to-mean ratio increases the barrel energy demand for a given total muzzle energy. Results are also presented from the numerical analysis of both capacitor and homopolar generator systems.

    Khosravi, Hassan; Shiri, Mohammad E.; Khosravi, Hamid; Iranmanesh, Ehsan; Davoodi, Alireza

    Software agents are increasingly being used to represent humans in online auctions. Such agents have the advantages of being able to systematically monitor a wide variety of auctions and then make rapid decisions about what bids to place in what auctions. They can do this continuously and repetitively without losing concentration. To provide a means of evaluating and comparing (benchmarking) research methods in this area the trading agent competition (TAC) was established. This paper describes the design, of TACtic. Our agent uses multi behavioral techniques at the heart of its decision making to make bidding decisions in the face of uncertainty, to make predictions about the likely outcomes of auctions, and to alter the agent's bidding strategy in response to the prevailing market conditions.

  7. Marketing strategies and tactics in a period of recession

    Full Text Available Recession is an extremely difficult period for most companies. Especially when a recession has universal dimensions, many companies find themselves unprepared to face great challenges. While marketing in good times has a long-term focus, a broad scope, it is benefits- and opportunities-driven and proactive, in bad times it has a short-term focus, limited and narrow scope, it is cost-and sales-driven and reactive. Panic is not the right reaction. Such difficult times should be overcome through methodical and well planned actions. After all, research has shown that those companies that take a proactive stance and treat the recession as an opportunity are likely to come out of the crisis stronger than before. Specific marketing activities have been proved to be beneficial to companies during a downturn. Below we analyze, ten marketing survival strategies and tactics.

    2002-08-01

    The US Air Force's TASS (Tactical Automated Security System) program has been in existence since 1996. The TASS program meets the growing need to supplement security personnel with modern technology, when these forces are deployed around the world. TASS combines five equipment elements into an integrated security solution, providing both a detection and an assessment capability. TASS does this in a way which maximizes the mobility and user friendliness objectives of the system. In this paper, we will take a closer look at TASS. We will examine the concepts that drive the TASS development process. We will provide an overview of the TASS technical elements, and provide a roadmap for further development of those elements. Finally, we will provide recommendations to security providers who aim to have their products included in the TASS baseline of equipment.

    This paper presents the latest results that have been obtained by GMV in the Maritime Surveillance and Awareness (MSA) domain through the exploitation of the SIMONS suite within fully operational scenarios. Diversified actors have been interacted with from pure public authorities to pure private companies for different specific goals. Scenario conditions were also varying in terms of area and target of interest, input data sources, ancillary datasets and dissemination strategies. The results show that SIMONS is a very useful tool in MSA that can complement the tactical and strategic information that can be obtained through in-situ and classical surveillance means (airborne- and ship-based visual reconnaissance...). Beyond timely delivery of reports, the capability to detect small non-metallic targets and to categorize most of the detected spots are two of the most prominent and recognized features.

    This study aimed to analyze the technical and tactical aspects of young athletes during official taekwondo competitions. Fifty-nine youth taekwondo athletes (43 boys and 16 girls; age range: 10-12 years; weight category range: 59 kg) with at least 2 years of taekwondo training consisting of three 90-minute training sessions for 3 d·wk⁻¹ participated in this study. Thirty-seven matches (three 1-minute rounds, with 1-minute rest in between) were analyzed to verify the differences (p ≤ 0.05) in offensive and defensive actions in relation to gender (male, female), match outcome (winners, nonwinners), kicking leg (front, rear), and round (first, second, third). No difference emerged for gender and match outcome. With respect to defensive actions (8.4 ± 12.0%), youth athletes engaged more frequently (p < 0.0001) in offensive actions (91.6 ± 12.0%), which showed a significant decrease (p < 0.016) from the first round (42.3 ± 21.8%) to the second (33.1 ± 14.8%) and third (24.5 ± 16.0%) ones. Kicks performed with the rear leg (94.4 ± 7.8%) occurred more frequently (p < 0.0001) than those performed with the front leg (5.6 ± 7.8%). In considering that a high level of coordination is required to perform front-leg kicks and defensive actions necessitate a high level of tactical skills, these findings might indicate a not-yet complete attainment of fundamental coordinative capabilities in 10- to 12-year-old athletes, independently of match outcome. To enhance coordination capabilities in youth athletes, coaches are recommended to structure their training including skill-ability and sport-ability drills.

    2010-01-01

    Full Text Available Objective: to elaborate therapeutic and diagnostic tactics for bleedings from esophagogastric varices (EGV in an intensive care unit (ICU. Subjects and methods: The experience in treating 102 patients with profuse bleeding from EGV, admitted to the ICU, Acad. V. Vakhidov Republican Specialized Center of Surgery, in 2000—2008, was summarized. Results. The findings show that just less than 40% of the patients with hepatic cirrhosis are admitted for the clinical manifestations of active bleeding from EGV, the latter being profuse in 17.6%. These indicate that the noticeable admission preponderance of patients with first-degree blood loss and the low proportion of those with critical third-degree blood loss are noteworthy. Retrospective analysis demonstrated that hemostasis was achieved in 97 (95.1% patients, by applying solely conservative measures using a Blakemore tube (in both variants of its use. After removal of the Blakemore tube, stable hemostasis retained in 88.9% of the patients with bleedings from the veins of the middle third of the esophagus, in 71.8% of cases of those from its lower third and only in 24.1% of the patients with those from the cardiac stomach. Conclusion. According to the results of the study, we propose the therapeutic and diagnostic tactics for patients with profuse bleedings from EGV, which involve the use of a Blakemore tube and a complex of conservative measures with traditional hemostatic therapy, the administration of portal pressure-reducing agents to prevent or treat hepatic failure. Key words: bleeding, esophagogastric varices, hepatic failure, intensive therapy.

    Full Text Available Abstract Background Neuroimaging technology has afforded advances in our understanding of normal and pathological brain function and development in children and adolescents. However, noncompliance involving the inability to remain in the magnetic resonance imaging (MRI scanner to complete tasks is one common and significant problem. Task noncompliance is an especially significant problem in pediatric functional magnetic resonance imaging (fMRI research because increases in noncompliance produces a greater risk that a study sample will not be representative of the study population. Method In this preliminary investigation, we describe the development and application of an approach for increasing the number of fMRI tasks children complete during neuroimaging. Twenty-eight healthy children ages 9-13 years participated. Generalization of the approach was examined in additional fMRI and event-related potential investigations with children at risk for depression, children with anxiety and children with depression (N = 120. Essential features of the approach include a preference assessment for identifying multiple individualized rewards, increasing reinforcement rates during imaging by pairing tasks with chosen rewards and presenting a visual 'road map' listing tasks, rewards and current progress. Results Our results showing a higher percentage of fMRI task completion by healthy children provides proof of concept data for the recommended tactics. Additional support was provided by results showing our approach generalized to several additional fMRI and event-related potential investigations and clinical populations. Discussion We proposed that some forms of task noncompliance may emerge from less than optimal reward protocols. While our findings may not directly support the effectiveness of the multiple reward compliance protocol, increased attention to how rewards are selected and delivered may aid cooperation with completing fMRI tasks Conclusion The

    Irestig, Magnus; Timpka, Toomas

    2010-02-01

    We set out to examine design conflict resolution tactics used in development of large information systems for health services and to outline the design consequences for these tactics. Discourse analysis methods were applied to data collected from meetings conducted during the development of a web-based system in a public health context. We found that low risk tactics were characterized by design issues being managed within the formal mandate and competences of the design group. In comparison, high risk tactics were associated with irresponsible compromises, i.e. decisions being passed on to others or to later phases of the design process. The consequence of this collective disregard of issues such as responsibility and legitimacy is that the system design will be impossible to implement in factual health service contexts. The results imply that downstream responsibility issues have to be continuously dealt with in system development in health services.

    Latorella, Kara A.; Chamberlain, James P.

    2002-01-01

    We commonly describe environments and behavioral responses to environmental conditions as 'tactical' and 'strategic.' However theoretical research defining relevant environmental characteristics is rare, as are empirical investigations that would inform such theory. This paper discusses General Aviation (GA) pilots' descriptions of tactical/strategic conditions with respect to weather flying, and evaluates their ratings along a tactical/strategic scale in response to real convective weather scenarios experienced during a flight experiment with different weather information cues. Perceived risk was significantly associated with ratings for all experimental conditions. In addition, environmental characteristics were found to be predictive of ratings for Traditional IMC (instrument meteorological conditions), i.e., aural weather information only, and Traditional VMC (visual meteorological conditions), i.e., aural information and an external view. The paper also presents subjects' comments regarding use of Graphical Weather Information Systems (GWISs) to support tactical and strategic weather flying decisions and concludes with implications for the design and use of GWISs.

  6. Advanced Strategic and Tactical Relay Request Management for the Mars Relay Operations Service

    Allard, Daniel A.; Wallick, Michael N.; Gladden, Roy E.; Wang, Paul; Hy, Franklin H.

    2013-01-01

    This software provides a new set of capabilities for the Mars Relay Operations Service (MaROS) in support of Strategic and Tactical relay, including a highly interactive relay request Web user interface, mission control over relay planning time periods, and mission management of allowed strategic vs. tactical request parameters. Together, these new capabilities expand the scope of the system to include all elements critical for Tactical relay operations. Planning of replay activities spans a time period that is split into two distinct phases. The first phase is called Strategic, which begins at the time that relay opportunities are identified, and concludes at the point that the orbiter generates the flight sequences for on board execution. Any relay request changes from this point on are called Tactical. Tactical requests, otherwise called Orbit - er Relay State Changes (ORSC), are highly restricted in terms of what types of changes can be made, and the types of parameters that can be changed may differ from one orbiter to the next. For example, one orbiter may be able to delay the start of a relay request, while another may not. The legacy approach to ORSC management involves exchanges of e-mail with "requests for change" and "acknowledgement of approval," with no other tracking of changes outside of e-mail folders. MaROS Phases 1 and 2 provided the infrastructure for strategic relay for all supported missions. This new version, 3.0, introduces several capabilities that fully expand the scope of the system to include tactical relay. One new feature allows orbiter users to manage and "lock" Planning Periods, which allows the orbiter team to formalize the changeover from Strategic to Tactical operations. Another major feature allows users to interactively submit tactical request changes via a Web user interface. A third new feature allows orbiter missions to specify allowed tactical updates, which are automatically incorporated into the tactical change process

    2016-06-01

    Full Text Available The main objective was to analyze a friendly match of youth elite soccer players identifying the variance of tactical and physiological response parameters during the game. In addition, detecting the impact of both halves on player performance. For the purposes of this study twenty-two U19 players were analyzed playing 11v11. Activity profile, heart rate (HR and HRmax, grouped in five different zones were analyzed via Bluetooth technology, technical performance was analyzed by the Team Sport Assessment Procedure (TSAP, and tactical performance was measured by Social Network Analysis. A comparison of heart rate responses showed significant main effects in the halves (p = 0.001; η p 2 = 0.623. A comparison between tactical position and technical performance had significant main effects (p = 0.001; η p 2 = 0.390. Tactical position showed statistically significant effects on tactical prominence (p = 0.002; η p 2 = 0.296. Therefore, fatigue is a component distinguished in technical/tactical parameters, such as volume of play and efficiency index. Results suggest that fatigue effects may constrain technical performance and, for that reason, the use of instruments to monitor the fatigue effect during matches may be suggested.

    Lewis, J A; Pitcher, T E

    2017-04-01

    This study examined whether polyandrous female Chinook salmon Oncorhynchus tshawytscha obtain benefits compared with monandrous females through an increase in hatching success. Both of the alternative reproductive tactics present in male O. tshawytscha (large hooknoses and small, precocious jacks) were used, such that eggs were either fertilized by a single male (from each tactic) or multiple males (using two males from the same or different tactics). The results show that fertilized eggs from the polyandrous treatments had a significantly higher hatching success than those from the monandrous treatments. It is also shown that sperm speed was positively related with offspring hatching success. Finally, there were tactic-specific effects on the benefits females received. The inclusion of jacks in any cross resulted in offspring with higher hatching success, with the cross that involved a male from each tactic providing offspring with the highest hatching success than any other cross. This study has important implications for the evolution of multiple mating and why it is so prevalent across taxa, while also providing knowledge on the evolution of mating systems, specifically those with alternative reproductive tactics. © 2016 The Fisheries Society of the British Isles.

    Takegaki, T; Kaneko, T; Matsumoto, Y

    2013-02-01

    Field and laboratory studies were conducted to examine the effects of nest availability and body size on changes in male mating tactics from sneaking to nest-holding in the dusky frillgoby Bathygobius fuscus. In the field, the body size of nest-holding males decreased from early to mid-breeding season, suggesting the possibility of a change in the tactics of sneaker males to nest-holding. Many sneaker males did not use vacant spawning nests even when size-matched nests were available, but they continued to reproduce as sneakers. Similarly, in aquarium experiments with available vacant nests, some sneaker males became nest-holders irrespective of their body size, but some did not. These results showed that nest availability is not a limiting factor for changes in tactics by sneaker males in this species. Because tactic-unchanged sneaker males were co-housed with larger nest-holding males in the tanks, the body size of nearby nest-holding males may have affected the decision to change tactics for sneaker males. Moreover, smaller individuals among tactic-changed males tended to spend more time until spawning, probably because they had relatively larger costs and smaller benefits of reproduction as nest-holding males compared to larger males.

One hundred and seventy-seven young adults (65 men, 112 women) completed questionnaires that included measures of online and offline mate-retention tactics, Facebook jealousy, Facebook surveillance, and intimate partner violence. A factor analysis yielded four subscales for the Facebook Mate-Retention Tactic Inventory (FMRTI): Care and Affection, Jealousy and Surveillance, Possession Signals, and Punishment of Infidelity Threat. The FMRTI total scores were positively correlated with Facebook jealousy, Facebook surveillance, and use of offline mate-retention tactics. The Jealousy and Surveillance subscale uniquely predicted intimate partner psychological and physical aggression over and above existing measures. Facebook mate-retention tactics fully mediated the relation between Facebook jealousy and both intimate partner psychological and physical aggression. The current study provides preliminary evidence for conceptualizing Facebook as an environment for the use of mate-retention tactics that have real-life implications for intimate partner violence.

    While tactical performance in competition has been analysed extensively, the assessment of training processes of tactical behaviour has rather been neglected in the literature. Therefore, the purpose of this study is to provide a methodology to assess the acquisition and implementation of offensive tactical behaviour in team handball. The use of game analysis software combined with an artificial neural network (ANN) software enabled identifying tactical target patterns from high level junior players based on their positions during offensive actions. These patterns were then trained by an amateur junior handball team (n = 14, 17 (0.5) years)). Following 6 weeks of tactical training an exhibition game was performed where the players were advised to use the target patterns as often as possible. Subsequently, the position data of the game was analysed with an ANN. The test revealed that 58% of the played patterns could be related to the trained target patterns. The similarity between executed patterns and target patterns was assessed by calculating the mean distance between key positions of the players in the game and the target pattern which was 0.49 (0.20) m. In summary, the presented method appears to be a valid instrument to assess tactical training.

    Full Text Available The US Department of Defense (DoD routinely uses wireless sensor networks (WSNs for military tactical communications. Sensor node die-out has a significant impact on the topology of a tactical WSN. This is problematic for military applications where situational data is critical to tactical decision making. To increase the amount of time all sensor nodes remain active within the network and to control the network topology tactically, energy efficient routing mechanisms must be employed. In this paper, we aim to provide realistic insights on the practical advantages and disadvantages of using established routing techniques for tactical WSNs. We investigate the following established routing algorithms: direct routing, minimum transmission energy (MTE, Low Energy Adaptive Cluster Head routing (LEACH, and zone clustering. Based on the node die out statistics observed with these algorithms and the topological impact the node die outs have on the network, we develop a novel, energy efficient zone clustering algorithm called EZone. Via extensive simulations using MATLAB, we analyze the effectiveness of these algorithms on network performance for single and multiple gateway scenarios and show that the EZone algorithm tactically controls the topology of the network, thereby maintaining significant service area coverage when compared to the other routing algorithms.

    Law enforcement tactical incidents involve high-risk operations that exceed the capabilities of regular, uniformed police. Despite the existence of tactical teams for 50 years, little is known about the frequency or nature of emergency medical services (EMS) response to tactical events in the United States. The purpose of this study was to perform a descriptive analysis of tactical events reported to a national EMS database. Descriptive analysis of the 2012 National Emergency Medical Services Information System (NEMSIS) Public Release research data set, containing EMS emergency response data from 41 states. A total of 17,479,328 EMS events were reported, of which 3,953 events were coded as "Activation-Tactical or SWAT Specialty Service/Response Team." The most common level of prehospital care present on scene was basic life support (55.2%). The majority (72.3%) of tactical incident activations involved a single patient; mass casualty incidents occurred in 0.5% of events. The most common EMS response locations were homes (48.4%), streets or highways (37.0%), and public buildings (6.3%). The mean age of treated patients was 44.1 years ± 22.0 years; 3.5% of tactical incident activation patients were aged 8 years or less. Injuries were coded as firearm assault in 14.8% and as chemical exposure in 8.9% of events. Cardiac arrest occurred in 5.1% of patients, with the majority (92.2%) occurring prior to EMS arrival. The primary symptoms reported by EMS personnel were pain (37.4%), change in responsiveness (13.1%), and bleeding (8.1%). Advanced airway procedures occurred in 30 patients. No patients were documented as receiving tourniquets or needle thoracostomy. Approximately 11 EMS responses in support of law enforcement tactical operations occur daily in the United States. The majority occur in homes and involve a single patient. Advanced airway procedures are required in a minority of patients. Cardiac arrest is rare and occurs prior to EMS response in the majority of

    What constitutes jointly Poisson processes remains an unresolved issue. This report reviews the current state of the theory and indicates how the accepted but unproven model equals that resulting from the small time-interval limit of jointly Bernoulli processes. One intriguing consequence of these models is that jointly Poisson processes can only be positively correlated as measured by the correlation coefficient defined by cumulants of the probability generating functional.

    Polygynous males can change their mating tactics across their lifetime, but information is scarce on the flexibility of this trait within a given season and the relative costs and benefits of using different tactics. Here, we monitored individually marked male reindeerRangifer tarandus and classified their mating tactics as harem-defense, sneaking, or mixed. The costs of the male reproductive effort were assessed using both direct (i.e. percentage of body mass lost) and indirect measures (i.e. activity patterns such as feeding, standing, and walking), while mating group size and reproductive success were recorded as mating ef-fort benefits. Our results show that reindeer males may switch between the harem-defense and sneaking tactics throughout the same breeding season, providing further support to the notion that reproductive tactics are flexible in ungulates. The costs and benefits of male mating effort vary according to the mating tactic, reaching the highest values in harem-holders and the lowest values in sneaking males. Moreover, males who switched between the sneaking tactic and the harem-defence tactic tended to achieve higher mating success than males who consistently used the least costly tactic. Indeed, all harem-holders successfully sired offspring, whereas only two out of three mixed-tactic males sired one calf, and sneaking males did not sire any calves. In conclusion, our results show that reindeer males can modulate their mating efforts during the same breeding season by switching between the most costly harem-defense tactic and the least costly sneaking tactic, suggesting individual solutions to the balance between reproductive effort and mating opportunities [Current Zoology 61 (5): 802–810, 2015].

    The temporomandibular joint (TMJ) is probably the most complex human joint. As in all joints, its prosthetic replacement may be indicated in selected cases. Significant advances have been made in the design of TMJ prostheses during the last three decades and the indications have been clarified. The aim of our work was to make an update on the current total TMJ total joint replacement. Indications, contraindications, prosthetic components, advantages, disadvantages, reasons for failure or reoperation, virtual planning and surgical protocol have been exposed.

    Isolated subtalar joint arthrodesis has gained popularity more recently. Research has shown that it preserves rearfoot motion, does not increase the risk of arthritis in adjacent joints, and is not an especially complex operative procedure. It decreases the chance of midtarsal joint nonunion and malunion postoperatively. This article takes an in-depth approach to isolated talocalcaneal fusions. Anatomy and biomechanics of the subtalar joint are reviewed. Clinical presentation and radiologic evaluation are discussed. Conservative treatment, operative technique, and postoperative management are included. Copyright © 2012 Elsevier Inc. All rights reserved.

    Fungicide-resistance management would be more effective if principles governing the selection of resistant strains could be determined and validated. Such principles could then be used to predict whether a proposed change to a fungicide application program would decrease selection for resistant strains. In this review, we assess a governing principle that appears to have good predictive power. The principle states that reducing the product of the selection coefficient (defined as the difference between the per capita rate of increase of the sensitive and resistant strains) and the exposure time of the pathogen to the fungicide reduces the selection for resistance. We show that observations as well as modeling studies agree with the predicted effect (i.e., that a specific change to a fungicide program increased or decreased selection or was broadly neutral in its effect on selection) in 84% of the cases and that only 5% of the experimental results contradict predictions. We argue that the selection coefficient and exposure time principle can guide the development of resistance management tactics.

    This paper addresses the problem of enabling Command and Control (C2) and data exfiltration functions for missions using small, unmanned, airborne surveillance and reconnaissance platforms. The authors demonstrated the feasibility of using existing commercial wireless networks as the data transmission infrastructure to support Unmanned Aerial Vehicle (UAV) autonomy functions such as transmission of commands, imagery, metadata, and multi-vehicle coordination messages. The authors developed and integrated a C2 Android application for ground users with a common smart phone, a C2 and data exfiltration Android application deployed on-board the UAVs, and a web server with database to disseminate the collected data to distributed users using standard web browsers. The authors performed a mission-relevant field test and demonstration in which operators commanded a UAV from an Android device to search and loiter; and remote users viewed imagery, video, and metadata via web server to identify and track a vehicle on the ground. Social media served as the tactical data link for all command messages, images, videos, and metadata during the field demonstration. Imagery, video, and metadata were transmitted from the UAV to the web server via multiple Twitter, Flickr, Facebook, YouTube, and similar media accounts. The web server reassembled images and video with corresponding metadata for distributed users. The UAV autopilot communicated with the on-board Android device via on-board Bluetooth network.

    Full Text Available Objective: to assess the immediate results of surgical interventions for colorectal cancer complicated by perforation.Materials and methods. The immediate results of surgical treatment were retrospectively analyzed in 56 patients with colorectal cancer complicated by perforated colon cancer, who had been treated at Smolensk surgical hospitals in 2001 to 2013. Patients with diastatic perforation of the colon in the presence of decompensated obturation intestinal obstruction of tumor genesis were not included into this investigation.Results. The immediate results of uni- and multistage surgical interventions were analyzed in relation to the extent of peritonitis and the stage of colon cancer. More satisfactory immediate results were observed after multistage surgical treatment. Following these interventions, a fatal outcome of disseminated peritonitis in the presence of performed colorectal cancer was recorded in 8 (53.3 % cases whereas after symptomatic surgery there were 11 (67.8 % deaths. A fatal outcome was noted in 1 case (7.7 % after multistage surgery.Discussion. The results of surgical treatment in the patients with perforated colorectal cancer are directly related to the degree of peritonitis and the choice of surgical tactics.

  14. Tessellated structure from motion for midrange perception and tactical planning

    2009-05-01

    A typical structure from motion (SFM) technique is to construct 3-D structures from the observation of the motions of salient features tracked over time. Although the sparse feature-based SFM provides additional solutions to robotic platforms as a tool to augment navigation performance, the technique often fails to produce dense 3-D structures due to the sparseness that is introduced during the feature selection and matching processes. For midrange sensing and tactical planning, it is important to have a dense map that is able to provide not only 3-D coordinates of features, but also clustered terrain information around the features for better thematic representation of the scene. In order to overcome the shortfalls embedded in the sparse feature-based SFM, we propose an approach that uses Voronoi decomposition with an equidistance-based triangulation that is applied to each of segmented and classified regions. The set of the circumcenters of the circum-hyperspheres used in the triangulation is formed with the feature points extracted from the SFM processing. We also apply flat surface detection to find traversable surface for a robotic vehicle to be able to maneuver safely on.

  15. Male dimorphism and alternative reproductive tactics in harvestmen (Arachnida: Opiliones).

    2014-11-01

    Strong sexual selection may lead small males or males in poor condition to adopt alternative reproductive tactics (ARTs) as a way to avoid the risk of being completely excluded from the mating pool. ARTs, sometimes accompanying morphological dimorphism among males, are taxonomically widespread, especially common in arthropods. Here we review the current knowledge on ARTs and male dimorphism in a diverse but relatively overlooked group of arachnids, the order Opiliones, popularly known as harvestmen or daddy long-legs. We begin with a summary of harvestman mating systems, followed by a review of the two lines of evidence for the presence of ARTs in the group: (1) morphological data from natural populations and museum collections; and (2) behavioral information from field studies. Despite receiving less attention than spiders, scorpions and insects, our review shows that harvestmen are an exciting group of organisms that are potentially great models for sexual selection studies focused on ARTs. We also suggest that investigating the proximate mechanisms underlying male dimorphism in the order would be especially important. New research on ARTs and male dimorphism will have implications for our understanding of the evolution of mating systems, sperm competition, and polyandry.

    Full Text Available Aim. The aim of the study was a relation between the borderline personality disorder and psychological gender, and tendency to use various manipulation tactics in everyday life and therapeutic context.Methods. The study used the Psychological Gender Inventory (A. Kuczyńska, 1992, and self-developed questionnaire for evaluating the tendency to use manipulation tactics and a survey evaluating manipulation in therapeutic contact. The studied group included: 30 patients with diagnosed BPD, 30 people a control group and 125 therapists.Results. The study of psychological gender showed that in the patient group the level of masculinity was significantly lower. Results showed that 88% of the therapists participating in the study confirmed that they have experienced manipulation attempts from patients. The therapists assessed the tendency of patientsto use manipulation tactics as greater than it was declared by the patients themselves. When compared to the control group, the patients indeed demonstrated a greater tendency to use the tactics of begging,threatening and threatening to break a close relationship and a lesser tendency to use the tactic of seduction. In the view of the therapists, during therapy patients most often used the tactics of lying and guilt induction.Conclusions. Manipulation is frequently used by BPD patients both in everyday life and in therapeutic contact. The most common reasons for using manipulation is to obtain benefits and to avoid negativeconsequences. It is necessary to conduct further research in this field and educate those who work with psychiatric patients in order to make them develop the ability to detect manipulation attempts and cope with such tactics.

  17. Mechanics of Sheeting Joints

    2015-12-01

    Physical breakdown of rock across a broad scale spectrum involves fracturing. In many areas large fractures develop near the topographic surface, with sheeting joints being among the most impressive. Sheeting joints share many geometric, textural, and kinematic features with other joints (opening-mode fractures) but differ in that they are (a) discernibly curved, (b) open near the topographic surface, and (c) form subparallel to the topographic surface. Where sheeting joints are geologically young, the surface-parallel compressive stresses are typically several MPa or greater. Sheeting joints are best developed beneath domes, ridges, and saddles; they also are reported, albeit rarely, beneath valleys or bowls. A mechanism that accounts for all these associations has been sought for more than a century: neither erosion of overburden nor high lateral compressive stresses alone suffices. Sheeting joints are not accounted for by Mohr-Coulomb shear failure criteria. Principles of linear elastic fracture mechanics, together with the mechanical effect of a curved topographic surface, do provide a basis for understanding sheeting joint growth and the pattern sheeting joints form. Compressive stresses parallel to a singly or doubly convex topographic surface induce a tensile stress perpendicular to the surface at shallow depths; in some cases this alone could overcome the weight of overburden to open sheeting joints. If regional horizontal compressive stresses, augmented by thermal stresses, are an order of magnitude or so greater than a characteristic vertical stress that scales with topographic amplitude, then topographic stress perturbations can cause sheeting joints to open near the top of a ridge. This topographic effect can be augmented by pressure within sheeting joints arising from water, ice, or salt. Water pressure could be particularly important in helping drive sheeting joints downslope beneath valleys. Once sheeting joints have formed, the rock sheets between

    The purposes of this study were to evaluate the relationship between correlation of MR joint effusion of the temporomandibular joint and disk position, to evaluate the relationship between joint effusion and aging, and to assess the frequency of MR joint effusion of bilateral temporomandibular joints. The temporomandibular joints of 192 patients with clinical symptoms of temporomandibular joint disorders were imaged bilaterally using high field, surface-coil MR imaging. Oblique sagittal and coronal proton density-weighted and T2-weighted images were obtained. Imaging findings of joint effusion were correlated with disk position, aging, and bilateral temporomandibular joints. MR showed effusion in 4% of the joints with normal superior disk position, 36% of the joints with disk displacement with reduction, and 45% of the joints with disk displacement without reduction. There were significant differences in the incidence of joint effusion between normal disk position and anterior disk displacement with or without reduction. Younger patients less than 40 years were significant higher the incidence of joint effusion than those of older patients. A significant association was seen between joint effusion and aging. MR showed effusion in 17% of the unilateral temporomandibular joint, 24% of the bilateral temporomandibular joints. There was no significant difference between unilateral and bilateral case. These results indicated that joint effusion using MR imaging was associated with varied temporomandibular joint pathologic states. (author)

    The structure and policies governing joint appointments discussed above, are developed primarily through cooperation and collaboration between nursing service and education institutions. The joint appointee participates in the process of negotiation of salary, benefits and role responsibilities and exploration of the implications of the appointment for personal career development. Implementation and maintenance of the appointment requires the collaborative efforts of the joint appointee with both contracting agencies. Factors influencing the functioning of joint appointees have been identified and strategies to facilitate functioning presented. The joint appointee must be independent in thought and action yet adaptable to work within the boundaries of two social systems with differing values and expectations. Nursing management, peers and students can provide the support needed to overcome the frustrations and to achieve the rewards inherent in successful implementation of an exciting and innovative role.

  2. Tactics as Empirical and Conceptual objects: Patient Activism and the Politics of Thalassaemia in Cyprus

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available This article explores tactics as political technologies in the context of health and patient activism. It does so by exploring how the PanCyprian Thalassaemia Association––a thalassaemia patients association situated in Cyprus––opposed a medical rationing scheme imposed by the Cypriot government and managed to overturn the decision. I make the case that “tactics,” for patient associations, are practices capable of rendering the political problematics of their illness visible to public and governmental perception, and propose four tactics by which the PTA was able to achieve such task. By putting the given event in conversation with STS and anthropological literature the article attempts to productively entangle tactics in their empirical and conceptual guises. This serves a two-fold purpose: That of putting together a repertoire of practices which patient associations can use to conduct politics, and that of facilitating connection between patient associations through these proposed practices. The article concludes with some more general considerations regarding an empirical-conceptual project on tactics.

    Firefighters' thermal burden is generally attributed to high heat loads from the fire and metabolic heat generation, which may vary between job assignments and suppression tactic employed. Utilising a full-sized residential structure, firefighters were deployed in six job assignments utilising two attack tactics (1. Water applied from the interior, or 2. Exterior water application before transitioning to the interior). Environmental temperatures decreased after water application, but more rapidly with transitional attack. Local ambient temperatures for inside operation firefighters were higher than other positions (average ~10-30 °C). Rapid elevations in skin temperature were found for all job assignments other than outside command. Neck skin temperatures for inside attack firefighters were ~0.5 °C lower when the transitional tactic was employed. Significantly higher core temperatures were measured for the outside ventilation and overhaul positions than the inside positions (~0.6-0.9 °C). Firefighters working at all fireground positions must be monitored and relieved based on intensity and duration. Practitioner Summary: Testing was done to characterise the thermal burden experienced by firefighters in different job assignments who responded to controlled residential fires (with typical furnishings) using two tactics. Ambient, skin and core temperatures varied based on job assignment and tactic employed, with rapid elevations in core temperature in many roles.

    2015-09-01

    Full Text Available The article represents the results of empirical study of gender differences in the strategies, tactics, importance and effectiveness of self-presentation. Participants (25 women and 25 men completed self-report measures of self-presentation (self-presentation tactics scale, self-control (self-monitoring scale, importance of self-presentation in various fields of communication. The results indicated that feminine individuals are significantly more likely to use defensive tactics of self-presentation, such as an “apology” and a “supplication”. They also use the strategies of “attractive behavior”. Masculine individuals are more likely to use the strategy “power influence” and the corresponding tactic “intimidation”. Androgynous individuals are significantly more likely to use the strategy “refusal” and some other tactics, such as “excuse”, “justification” and “denying responsibility”. It was revealed that the self-presentation is more important for feminine and androgynous individuals, than masculine individuals. In addition to this, self-presentation in the family is more important for androgynous individuals, while in professional and interpersonal spheres self-presentation is very important for feminine individuals. Gender differences do not affect the effectiveness of self-presentation. The results reflect the stereotypical characteristics and social expectations regarding the conduct of a person of a particular gender.

  5. Can alternative mating tactics facilitate introgression across a hybrid zone by circumventing female choice?

    Reproductive barriers and divergence in species' mate recognition systems underlie major models of speciation. However, hybridization between divergent species is common, and classic mechanisms to explain permeable reproductive barriers rarely consider how an individual may attain reproductive success. Alternative mating tactics (AMTs) exist in various forms across animal taxa. Such tactics may allow poorer quality individuals to gain mating opportunities and facilitate introgression either through asymmetrical positive selection or by circumventing female choice altogether in areas of secondary contact. One such tactic is satellite behaviour in frogs, where silent males perch near advertisers in an attempt to intercept females. To test whether such satellite male tactics are context-dependent and favoured by hybrids, we genotyped and quantified the morphology of 80 male spring peeper (Pseudacris crucifer) individuals involved in caller-satellite associations from a secondary contact zone between two intraspecific mitochondrial lineages. Irrespective of population, satellite behaviour was best predicted by size but not body condition. Within the contact zone, pure individuals showed a significantly greater probability of being active callers, whereas hybrids of one lineage were more likely to adopt the satellite tactic. We suggest that satellite behaviour in P. crucifer promotes introgression, breaks down reproductive isolating barriers and contributes to asymmetrical introgression in this secondary contact zone. AMTs may thus be an underexplored but important alternative to oft-discussed causes of genetic discordance found in hybrid zones.

    The work activities of industrial engineers (IEs) and ergonomists drive workplace changes. The purpose of this study is to compare the work practices of the two professions and examine (1) how IEs and ergonomists gain influence over workplace changes and (2) whether there are prevailing types of intentional interaction behaviours called Power bases (PB) present in the interaction tactics they employ. The study identified key behavioural strategies used by the interviewees to successfully influence workplace changes; these were then mapped to their corresponding PB. Results showed that IEs and ergonomists were successfully influencing workplace changes using several tactics across the spectrum of PB, with the exception of Reward and Coercion. The study concludes with a list of recommended workplace change agent tactics, and proposes that a PB 'analytical lens' can serve to increase the budding ergonomists' critical and analytical skills when considering possible workplace change tactics. Practitioner Summary: This interview study examines how workplace ergonomics change agents, represented by the two professions: industrial engineers and ergonomists, perceive and exercise their capacity to influence workplace change. Key behavioural tactics that interviewees have found successful are reported, alongside effects on short- and long-term relations with other workplace-influencing stakeholders.

    Full Text Available Parents and children are genetically related but not genetically identical, which means that their genetic interests overlap but also diverge. In the area of mating, this translates into children making mate choices that are not in the best interest of their parents. Parents may then resort to manipulation in order to influence their children's mating decisions in a way that best promotes the former's interests. This paper attempts to identify the structure of manipulation tactics that parents employ on their daughters and sons, as well as on their daughters' and sons' mates, and also to estimate their prevalence. On the basis of the structure of the derived tactics, four hypotheses are tested: Mothers are more willing than fathers to use manipulation tactics; parents are willing to use more manipulation on their daughters than on their sons; the personality of parents predicts the use of tactics on their children and on their children's mates; and the personality of children and of children's mates predicts the use of tactics on them. Evidence from two independent studies provides support for the first three hypotheses, but mixed support for the fourth hypothesis. The implications of these findings are further discussed.

    Mate retention is an important problem in romantic relationships because of mate poachers, infidelity, and the risk of outright defection. The current study (N=892) represents the first study of mate retention tactics conducted in Spain. We tested hypotheses about the effects of gender, relationship commitment status, and personality on mate retention tactics. Women and men differed in the use of resource display, appearance enhancement, intrasexual violence, and submission/self-abasement as mate retention tactics. Those in more committed relationships reported higher levels of resource display, appearance enhancement, love, and verbal signals of possession. Those in less committed relationships more often reported intentionally evoking jealousy in their partner as a mate retention tactic. Personality characteristics, particularly Neuroticism and Agreeableness, correlated in coherent ways with mate retention tactics, supporting two evolution-based hypotheses. Discussion focuses on the implications, future research directions, and interdisciplinary syntheses emerging between personality and social psychology and evolutionary psychology. © 2011 The Authors.

    Full Text Available In this letter, we propose graph theory-based heuristics for jointly assigning frequency and antenna polarization in a cluster-based tactical communication environment (e.g., military communications. In addition to considering the frequency assignment problem (which is an NP-hard problem, we also consider the polarization assignment issue. A practical antenna and a 3D ray tracing-based simulator are exploited to measure the interference. We show that the suggested heuristics are nearly optimal in terms of chromatics and their low complexity makes them suitable for practical usage.

    Our NASA MEaSUREs project is producing a new, enhanced resolution gridded Earth System Data Record for the entire satellite passive microwave (SMMR, SSM/I-SSMIS and AMSR-E) time series. Our project goals are twofold: to produce a well-documented, consistently processed, high-quality historical record at higher spatial resolutions than have previously been available, and to transition the production software to the NSIDC DAAC for ongoing processing after our project completion. In support of these goals, our distributed team at BYU and NSIDC faces project coordination challenges to produce a high-quality data set that our user community will accept as a replacement for the currently available historical versions of these data. We work closely with our DAAC liaison on format specifications, data and metadata plans, and project progress. In order for the user community to understand and support our project, we have solicited a team of Early Adopters who are reviewing and evaluating a prototype version of the data. Early Adopter feedback will be critical input to our final data content and format decisions. For algorithm transparency and accountability, we have released an Algorithm Theoretical Basis Document (ATBD) and detailed supporting technical documentation, with rationale for all algorithm implementation decisions. For distributed team management, we are using collaborative tools for software revision control and issue tracking. For reliably transitioning a research-quality image reconstruction software system to production-quality software suitable for use at the DAAC, we have adopted continuous integration methods for running automated regression testing. Our presentation will summarize bothadvantages and challenges of each of these tactics in ensuring production of a successful ESDR and an enduring production software system.

    Body size and female reproduction in the water monitor lizard(Varanus salvator) were studied. Forty-two adult females larger than 500 mm SVL and 32 adult males larger than 400 mm SVL were donated by local people in Ledong, Hainan under permit to our laboratory in Hainan in 2013 and 2014. The largest male and female measured 745 and 755 mm SVL, respectively. The mean SVL was greater in adult females than in adult males. Males had larger heads (head width) than females of the same SVL. The smallest reproductive female in our sample was 565 mm SVL. Females produced a single clutch of 17.1 (10−23) pliable-shelled eggs per breeding season stretching from mid-June and mid-September. Clutch size and clutch mass were all positively related to female SVL. However, there was no signiifcant linear relationship between egg mass and female SVL. Larger females generally produced more eggs, and thus heavier clutches than did smaller ones. There was no signiifcant linear relationship between relative clutch mass and female SVL. Phylogenetic generalized least squares (PGLS) analysis, accounting for phylogenetic relationships, showed that clutch size was positively correlated with mean maternal SVL in varanid lizards. PGLS analysis showed that phylogenetic relationships did not affect clutch (or/and egg) mass and the SVL although there were significant linear relationship between clutch (or/and egg) mass and mean maternal SVL. Therefore, we could draw some general conclusions about the body size and reproductive tactics in varanid lizards that larger females generally produced more eggs, larger eggs and thus heavier clutches than did smaller ones.

  14. Gestural Communication and Mating Tactics in Wild Chimpanzees.

    Directory of Open Access Journals (Sweden)

    Anna Ilona Roberts

    Full Text Available The extent to which primates can flexibly adjust the production of gestural communication according to the presence and visual attention of the audience provides key insights into the social cognition underpinning gestural communication, such as an understanding of third party relationships. Gestures given in a mating context provide an ideal area for examining this flexibility, as frequently the interests of a male signaller, a female recipient and a rival male bystander conflict. Dominant chimpanzee males seek to monopolize matings, but subordinate males may use gestural communication flexibly to achieve matings despite their low rank. Here we show that the production of mating gestures in wild male East African chimpanzees (Pan troglodytes schweunfurthii was influenced by a conflict of interest with females, which in turn was influenced by the presence and visual attention of rival males. When the conflict of interest was low (the rival male was present and looking away, chimpanzees used visual/ tactile gestures over auditory gestures. However, when the conflict of interest was high (the rival male was absent, or was present and looking at the signaller chimpanzees used auditory gestures over visual/ tactile gestures. Further, the production of mating gestures was more common when the number of oestrous and non-oestrus females in the party increased, when the female was visually perceptive and when there was no wind. Females played an active role in mating behaviour, approaching for copulations more often when the number of oestrus females in the party increased and when the rival male was absent, or was present and looking away. Examining how social and ecological factors affect mating tactics in primates may thus contribute to understanding the previously unexplained reproductive success of subordinate male chimpanzees.

    The Tactical Runway Configuration Management (TRCM) software tool was developed to provide air traffic flow managers and supervisors with recommendations for airport configuration changes and runway usage. The objective for this study is to conduct a benefits assessment at Memphis (MEM), Dallas Fort-Worth (DFW) and New York's John F. Kennedy (JFK) airports using the TRCM tool. Results from simulations using the TRCM-generated runway configuration schedule are compared with results using historical schedules. For the 12 days of data used in this analysis, the transit time (arrival fix to spot on airport movement area for arrivals, or spot to departure fix for departures) for MEM departures is greater (7%) than for arrivals (3%); for JFK, there is a benefit for arrivals (9%) but not for departures (-2%); for DFW, arrivals show a slight benefit (1%), but this is offset by departures (-2%). Departure queue length benefits show fewer aircraft in queue for JFK (29%) and MEM (11%), but not for DFW (-13%). Fuel savings for surface operations at MEM are seen for both arrivals and departures. At JFK there are fuel savings for arrivals, but these are offset by increased fuel use for departures. In this study, no surface fuel benefits resulted for DFW. Results suggest that the TRCM algorithm requires modifications for complex surface traffic operations that can cause taxi delays. For all three airports, the average number of changes in flow direction (runway configuration) recommended by TRCM was many times greater than the historical data; TRCM would need to be adapted to a particular airport's needs, to limit the number of changes to acceptable levels. The results from this analysis indicate the TRCM tool can provide benefits at some high-capacity airports. The magnitude of these benefits depends on many airport-specific factors and would require adaptation of the TRCM tool; a detailed assessment is needed prior to determining suitability for a particular airport.

    2017-07-01

    Full Text Available Background: The Conflict Tactics Scale 1 (CTS1 is a widely used self-report measure of abusive attitudes of parents towards children. The factor structure of the CTS1 still remains to be clarified. The aim of this study was to examine the factor structure of the Japanese version of the CTS1 for postpartum women in community settings. Method: The data in this study came from the Okayama and Kumamoto’s study. These were part of a larger survey using longitudinal questionnaire studies conducted in Japan from 2001 to 2002 and in 2011, respectively. In both study sites, the participant mothers were asked to fill in the CTS1 one month after delivery when they attended for check-up at the out-patient clinic. Results: A total of 1,150 questionnaires were collected, excluding the participants with missing values in the CTS1. Finally, 1,078 were included in the statistical analyses. Data of 1,078 women were divided into two parts. In the first halved sample (n=578, an exploratory factor analysis was conducted for the CTS1 items after exluding nine items with extremely low prevalence. It revealed 2-factor or 3-factor models. Then, we conducted a model comparison with the second halved sample (n=500, using confirmatory factor analysis. In terms of goodness-of-fit indeces, the 2-factor model was superior. Its subscales were Reasoning and Psycholosical Aggression. Conclusion: The 2-factor model of the CTS1 consisting of Reasoning and Psychological Aggression was superior to the 3-factor model. This is not inconsistent with the original authors’ theoretical model.

    Development of the SOAR telescope is currently underway. Project plans include many tactics for smooth assembly, integration, and validation of this new facility to be located on Cerro Pachon at the Cerro Tololo Inter-American Observatory in Chile. A small project team has been established to manage and engineer the development of the major subsystems that are combined in this high image quality 4.2-meter diameter telescope. The status and plans for the development of the 28m telescope are discussed. A modest-sized facility building is under construction by CTIO, the organization appointed to operate the facility for the SOAR partners. Each telescope subsystem is contracted on a firm fixed price basis and will include complete performance testing at the contractor's facility before acceptance and shipment to the site. To ensure seamless integration, representatives of each contractor will come to the site for assembly and testing in place. They join personnel from the Project Office, the new operations staff, and the CTIO maintenance organization to form integrated product teams for subsystem integration, SOAR eases integration by using and mandating common, commercial control software. The contractors, the SOAR team, and the instrument buildings are making extensive use of LabVIEW/BridgeVIEW running under Linux (with real-time extensions as necessary) on compactPCI chassis. The telescope will include sufficient instrumentation, including a possible adaptive optics system, to allow system testing and optimization. An exceptionally large instrument payload ensures that instruments can remain in place upon the telescope as they are delivered and brought on line.

    We aimed to analyse the effect of experience level in the psychophysiological response and specific fine motor skills of novel and expert parachute warfighters during a tactical combat parachute jump. We analysed blood oxygen saturation, heart rate, salivary cortisol, blood glucose, lactate and creatinkinase, leg strength, isometric hand-grip strength, cortical arousal, specific fine motor skills and cognitive anxiety, somatic anxiety and self-confident before and after a tactical combat parachute jump in 40 warfighters divided in two group, novel (n=17) and expert group (n=23). Novels presented a higher heart rate, lactate, cognitive anxiety, somatic anxiety and a lower self-confident than experts during the jump. We concluded that experience level has a direct effect on the psychophysiological response since novel paratroopers presented a higher psychophysiological response than compared to the expert ones, however this result neither affected the specific fine motor skills nor the muscle structure after a tactical combat parachute jump.

    Full Text Available AbstractConceptual small-sided games (CSSGs may be interesting as a methodology for training soccer players given its connection to the unpredictability that is inherent to soccer. Our aim was investigate, through videogrammetry, if the technical and tactical principles promoted through the adoption of distinct rules from two distinct CSSGs (maintaining ball possession; and progression to the target would actually be achieved. The study included 24 athletes assigned to 6-player teams. Our data showed that the CSSGs' organising principles create situations with differing levels of difficulty that obey the propositions of maintaining ball possession and progression to the target, i.e., CSSGs permit systematic training on technical and tactical components in order to emphasize the concepts adopted in this study in games context. Our data credit the CSSGs for teaching technical and tactical lessons that, when coupled with adequate physical conditioning, can facilitate a player's capacity to merge thoughts and events in different situations.

    2016-02-01

    Ankle arthritis results in a stiff and painful ankle and can be a major cause of disability. For people with end-stage ankle arthritis, arthrodesis (ankle fusion) is effective at reducing pain in the shorter term, but results in a fixed joint, and over time the loss of mobility places stress on other joints in the foot that may lead to arthritis, pain and dysfunction. Another option is to perform a total ankle joint replacement, with the aim of giving the patient a mobile and pain-free ankle. In this article we review the efficacy of this procedure, including how it compares to ankle arthrodesis, and consider the indications and complications.

    The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Tactical Medical Program provides tactical medical support for ATF's tactical Special Response Teams (SRTs) and investigative National Response Teams (NRTs) through the deployment of specially trained ATF Agent-Medics. All patient care activities are centrally coordinated through ATF Headquarters. A retrospective analysis of de-identified patient care reports (PCRs) from the ATF Tactical Medical Program from 2009 to 2012 was performed. Clinical and operational data were extracted from PCRs and were entered into a database by the research team. Descriptive and summative analyses were performed to assess patient type, law enforcement incident type, chief complaint, and interventions performed. Analysis was performed on the 254 charts. Nearly half (114; 44.9%) of patients encountered during the study period were law enforcement officers. High-risk warrant service was associated with one third (85; 33.5%) of the ATF medics' clinical encounters. The most common chief complaints of patients encountered were musculoskeletal pain/injury (57; 22.4%) and wounds/lacerations (57; 22.4%), followed by heat illness (17; 6.7%). The most common intervention was wound care (61; 26.9%), followed by control of bleeding with direct pressure (43; 18.9%). The most common medications administered were ibuprofen (28; 25.2%), topical antibiotic (12; 10.8%), and acetaminophen (12;10.8%). This multiyear analysis represents an important contribution to the growing body of scientific literature surrounding tactical medicine. The results of this analysis demonstrate a continued need for expanded scope of practice training, as well as enhanced treatment protocols for tactical medics. 2014.

    While debate in the health care literature continues with respect to the role of marketing, many industries are adopting a broadened perspective which recognizes the comprehensive role which marketing may assume at a variety of levels within the organization: marketing as culture, marketing as strategy, and marketing as tactics. A national study of general service hospitals suggests that, in many hospitals, the marketing function is indeed transcending its functional boundaries through enculturation of a marketing orientation, involvement in the strategic process of the organization, and expansion of tactical marketing activities. Hospitals which adopt and support this broadened role of marketing are witnessing a positive effect on performance.

  15. Case Studies of Attacks over Adaptive Modulation Based Tactical Software Defined Radios

    Directory of Open Access Journals (Sweden)

    David Fernandes Cruz Moura

    2012-01-01

    Full Text Available This paper presents case studies of attacks aimed at tactical software defined radios based on a classification with the most common sources of vulnerabilities, classes of attacks, and types of intrusions that military radio sets may suffer. Besides that, we also describe how attack mitigation strategies can impact the development of SDR infrastructures. By using such approach, we identify several possible sources of vulnerabilities, attacks, intrusions, and mitigation strategies, illustrating them onto typical tactical radio network deployment scenarios, as an initial and necessary step for the definition of realistic and relevant security requirements for military software defined radio applications.

  16. SUPPORTED CATALYST WITHOUT EXTERNAL ELECTRON DONOR FOR PROPYLENE POLYMERIZATION Ⅱ. TACTICITY DISTRIBUTION AND MICROSTRUCTURE OF POLYPROPYLENE

    Institute of Scientific and Technical Information of China (English)

    1998-01-01

    Propylene was polymerized with a novel supported Ziegler-Natta catalyst containing 2,2-di-iso-butyl-1,3-dimethoxy-propane (DIBDMP) as internal donor and in the absence of external donor. The tacticity distribution of polypropylene was obtained by using temperature rising elution fractionation (TREF) technique and microstructure of fractions was studied with 13C-NMR. Compared with the catalyst without electron donor, this catalyst gives a considerably narrower tacticity distribution. Fractionation data demonstrate that DIBDMP shows better performance than aromatic diester DNBP (di-n-butyl phthalate). Chemically inverted propylene units and less stereoblockiness are found in the first fraction. Possible reasons for these were presented.

    Science.gov (United States)

    Smith, Jeremy C.; Neitzke, Kurt W.; Bussink, Frank J. L.

    2008-01-01

    This paper presents the results from a study that investigates the performance of aspects of an Airborne Separation Assistance System (ASAS) under varying demand levels using realistic traffic patterns. This study only addresses the tactical aspects of an ASAS using aircraft state data (latitude, longitude, altitude, heading and speed) to detect and resolve projected conflicts. The main focus of this paper is to determine the extent to which sole reliance on the proposed tactical ASAS can maintain aircraft separation at demand levels up to three times current traffic. The effect of mixing ASAS equipped aircraft with non-equipped aircraft that do not have the capability to self-separate is also investigated.

    Full Text Available Orientation: Impression management tactics are utilised differently by people depending on the situation and the others around them.Research purpose: The purpose of the study was to identify the impression management tactics Zulu people display when they want to impress people in a work context.Motivation for this study: Organisations are competing for talented employees and people who contribute to the return on investment for the organisation. Individuals display impression tactics to influence the perceptions of others in the workplace, especially pertaining to performance appraisals and promotional opportunities.Research approach, design and method: The social constructivism paradigm was employed in conducting this study, following a phenomenological approach. The research sample consisted of 30 Zulu-speaking individuals from various organisations who were interviewed through semi-structured interviews. The researcher used thematic analysis to analyse the data.Main findings: The main findings in this study included impression management tactics that are used by Zulu people when attempting to impress people in the work context. The findings were divided into different categories (colleagues and supervisor. Conscientiousness,interpersonal amiability, openness and relational action are the themes that were reported as the most common impression management features people display at their workplace with colleagues. Themes that were reported when impressing a supervisor include conscientiousness,integrity, relational action and skilfulness.Practical/managerial implications: This study provides organisations with knowledge on the impression management tactics utilised by isiZulu employees. The nature of this information enables management to not misinterpret the use of certain tactics and will lead to more understanding and resilience by organisations and colleagues when working with isiZulu individuals.Contribution/value-add: This study

    1993-01-01

    Many recuperators have components which react to corrosive gases and are used in applications where the donor fluid includes highly corrosive gases. These recuperators have suffered reduced life, increased service or maintenance, and resulted in increased cost. The present joint when used with recuperators increases the use of ceramic components which do not react to highly corrosive gases. Thus, the present joint used with the present recuperator increases the life, reduces the service and maintenance, and reduces the increased cost associated with corrosive action of components used to manufacture recuperators. The present joint is comprised of a first ceramic member, a second ceramic member, a mechanical locking device having a groove defined in one of the first ceramic member and the second ceramic member. The joint and the mechanical locking device is further comprised of a refractory material disposed in the groove and contacting the first ceramic member and the second ceramic member. The present joint mechanically provides a high strength load bearing joint having good thermal cycling characteristics, good resistance to a corrosive environment and good steady state strength at elevated temperatures.

    Full Text Available The study was aimed at assessing the impact of relationship marketing tactics on customer loyalty in the Ghanaian mobile industry where deregulation has led to intense competition and scramble for market share. Marketers in the industry are employing variety of relationship marketing tactics to attract and retain customers. This research study adopted four relationship marketing tactics (service quality, price perception, brand image and value offered typical of a service industry and examined their impact on customer loyalty in the Ghanaian mobile industry. A self-completion questionnaire with a total of 40 closed questions was developed to gather field data. All of the items were measured by using a five-point Likert-type response scales, defined with 5 as strongly agree and 1 as strongly disagrees. Reliability test and some parametric and non-parametric tests were conducted and the results showed that there exist a positive significant relationship between each of the four relationship marketing tactics (namely service quality, price, value offered and brand image and customer loyalty. The results are consistent with evidence in the extant literature. The study provides insight and significant feedback from mobile phone users to the telecommunication operators. As the competitive environment increasingly becomes fierce, the voice and preferences of the customers are also becoming the priority. This finding is expected to serve as a guide and help to telecommunication managers in making informed judgment about the relationship marketing mix relevant to the present customer’s need that yields increase in revenue and profit.

    Full Text Available Basic properties of varieties of tactical thought of handballers are considered. The level of their display is shown for the sportswomen of different qualification. 78 sportswomen took part in research. For determination of parameters of tactical and playing thought the method of «Balltest» is utillized in an attack and defence. Priority of exactness and speed of thought is set depending on the level of sporting trade of handballers. Different influence of speed of thought is well-proven on the rightness of decision of playing situations of different orientation in the handballers of mass digits and high level of display of the indicated properties of thought for the sportswomen of high qualification. It is discovered that a level of display of basic properties of tactical thought is in defence substantially below of other varieties of thought. It is marked that with the increase of trade of players there were possibilities to growth of quantitative and speed parameters of tactical thought.

    Organisms that share the same genotype can develop into divergent phenotypes, depending on environmental conditions. In Atlantic salmon, young males of the same age can be found either as sneakers or immature males that are future anadromous fish. Just as the organism-level phenotype varies between divergent male developmental trajectories, brain gene expression is expected to vary as well. We hypothesized that rearing environment can also have an important effect on gene expression in the brain and possibly interact with the reproductive tactic adopted. We tested this hypothesis by comparing brain gene expression profiles of the two male tactics in fish from the same population that were reared in either a natural stream or under laboratory conditions. We found that expression of certain genes was affected by rearing environment only, while others varied between male reproductive tactics independent of rearing environment. Finally, more than half of all genes that showed variable expression varied between the two male tactics only in one environment. Thus, in these fish, very different molecular pathways can give rise to similar macro-phenotypes depending on rearing environment. This result gives important insights into the molecular underpinnings of developmental plasticity in relationship to the environment. ?? 2005 The American Genetic Association.

  11. Oxytocin receptor density is associated with male mating tactics and social monogamy.

    2012-03-01

    Despite its well-described role in female affiliation, the influence of oxytocin on male pairbonding is largely unknown. However, recent human studies indicate that this nonapeptide has a potent influence on male behaviors commonly associated with monogamy. Here we investigated the distribution of oxytocin receptors (OTR) throughout the forebrain of the socially monogamous male prairie vole (Microtus ochrogaster). Because males vary in both sexual and spatial fidelity, we explored the extent to which OTR predicted monogamous or non-monogamous patterns of space use, mating success and sexual fidelity in free-living males. We found that monogamous males expressed higher OTR density in the nucleus accumbens than non-monogamous males, a result that mirrors species differences in voles with different mating systems. OTR density in the posterior portion of the insula predicted mating success. Finally, OTR in the hippocampus and septohippocampal nucleus, which are nuclei associated with spatial memory, predicted patterns of space use and reproductive success within mating tactics. Our data highlight the importance of oxytocin receptor in neural structures associated with pairbonding and socio-spatial memory in male mating tactics. The role of memory in mating systems is often neglected, despite the fact that mating tactics impose an inherently spatial challenge for animals. Identifying mechanisms responsible for relating information about the social world with mechanisms mediating pairbonding and mating tactics is crucial to fully appreciate the suite of factors driving mating systems.

  12. Temporomandibular joint disorders.

    2007-11-15

    Temporomandibular joint disorders are common in adults; as many as one third of adults report having one or more symptoms, which include jaw or neck pain, headache, and clicking or grating within the joint. Most symptoms improve without treatment, but various noninvasive therapies may reduce pain for patients who have not experienced relief from self-care therapies. Physical therapy modalities (e.g., iontophoresis, phonophoresis), psychological therapies (e.g., cognitive behavior therapy), relaxation techniques, and complementary therapies (e.g., acupuncture, hypnosis) are all used for the treatment of temporomandibular joint disorders; however, no therapies have been shown to be uniformly superior for the treatment of pain or oral dysfunction. Noninvasive therapies should be attempted before pursuing invasive, permanent, or semi-permanent treatments that have the potential to cause irreparable harm. Dental occlusion therapy (e.g., oral splinting) is a common treatment for temporomandibular joint disorders, but a recent systematic review found insufficient evidence for or against its use. Some patients with intractable temporomandibular joint disorders develop chronic pain syndrome and may benefit from treatment, including antidepressants or cognitive behavior therapy.

    2011-09-01

    Full Text Available The temporo-mandibular joint (TMJ it’s a joint closely related to the skull base, the spine, and the jaws; all these anatomical structures must be taken in consideration when evaluating pain involving the tmj. In order to detect patients affected by pathology or dysfunctions of the tmj, physical examination is of great value in orienting the diagnosis. Inspection must consider the symmetry of the body, the dental status and the type of occlusion. Palpation is a way to assess contractiont involving the muscles of the masticatory system and of the neck. Auscultation, based on articular noise provides means to determine whether we are dealing with degeneration of the joint or a dislocation of the intrarticular disc. In order to confirm the diagnosis obtained with the clinical evaluation, it’s useful to perform imaging techniques as opt, tomography and TC of the tmj and electromyokineosiography – index of the mandibular functionality and of the muscles status. MRI and dynamic MRI are among the non invasive exams which give the greatest amount of information, regarding the disc position and the joint degeneration. Arthroscopy is an invasive technique that allows early diagnosis of degeneration and is helpful to reveal early inflammatory processes of the joint.

    Full Text Available Distal radioulnar joint is a trochoid joint relatively new in evolution. Along with proximal radioulnar joint , forearm bones and interosseous membrane, it allows pronosupination and load transmission across the wrist. Injuries around distal radioulnar joint are not uncommon, and are usually associated with distal radius fractures,fractures of the ulnar styloid and with the eponymous Galeazzi or Essex_Lopresti fractures. The injury can be purely involving the soft tissue especially the triangular fibrocartilage or the radioulnar ligaments.The patients usually present with ulnar sided wrist pain, features of instability, or restriction of rotation. Difficulty in carrying loads in the hand is a major constraint for these patients. Thorough clinical examination to localize point of tenderness and appropriate provocative tests help in diagnosis. Radiology and MRI are extremely useful, while arthroscopy is the gold standard for evaluation. The treatment protocols are continuously evolving and range from conservative, arthroscopic to open surgical methods. Isolated dislocation are uncommon. Basal fractures of the ulnar styloid tend to make the joint unstable and may require operative intervention. Chronic instability requires reconstruction of the stabilizing ligaments to avoid onset of arthritis. Prosthetic replacement in arthritis is gaining acceptance in the management of arthritis.

    2014-10-01

    Full Text Available Certain limitations remain unaddressed when utilizing the Teaching Games for Understanding approach, suggesting the need for more research on authentic assessment of skill development and tactical awareness in order to guide the design of developmentally appropriate curriculum materials. This study investigated physical education students’ (n=19; age: 13.71 ± 0.4 game performance during an invasion game, specifically the relationship between their skill execution and decision-making ability. The purpose of the study was twofold: (a to devise and implement a ‘game context’ approach to assess the game performance components and in doing so, (b to provide information that could be used to design suitable learning progressions within tactical teaching approaches. Students’ game performance was videotaped, and measures of skill execution and decision-making were developed from observational analyses. Decision-making was measured at two levels: a decision making restricted to the selection of technical-tactical skills (i.e., passing, moving with the ball, getting free, marking, tackling, double teaming and interception; and b decisionmaking in the adaptation to the tactical contexts of the game. Participants played a 5 vs. 5 modified eight-minute team handball game. Participants scored significantly higher in penetrating-the-defense context adaptation than in keepingthe- ball context adaptation. Participants showed a higher efficiency in decision-making than in execution in most of the technical-tactical skills; including on-the-ball over off-the-ball decision-making, and in attack compared to defensive execution. The findings also revealed significant relationships between decision-making and skill execution in shooting, tackling and passing

    Full Text Available Studies of a welded joint were described. The joint was made as a result of the reconstruction of a truss and one of the possible means to make a repair. The studies were of a simulation character and were targeted at the detection of welding defects and imperfections thatshould be eliminated in a real structure. A model was designed and on this model the tests and examinations were carried out. The modelwas made under the same conditions as the conditions adopted for repair. It corresponded to the real object in shape and dimensions, and in the proposed technique of welding and welding parameters. The model was composed of five plates joined together with twelve beads.The destructive and non-destructive tests were carried out; the whole structure and the respective welds were also examined visually. Thedefects and imperfections in welds were detected by surface methods of inspection, penetration tests and magnetic particle flaw detection.The model of the welded joint was prepared by destructive methods, a technique that would never be permitted in the case of a realstructure. For the investigations it was necessary to cut out the specimens from the welded joint in direction transverse to the weld run. The specimens were subjected to metallographic examinations and hardness measurements. Additionally, the joint cross-section was examined by destructive testing methods to enable precise determination of the internal defects and imperfections. The surface methods were applied again, this time to determine the severity of welding defects. The analysis has proved that, fabricated under proper conditions and with parameters of the welding process duly observed, the welded joint has good properties and repairs of this type are possible in practice.

    1998-01-01

    Buff-breasted sandpipers use a variety of mating tactics to acquire mates, including remaining at a single lek for most of the breeding season, attending multiple leks during the season, displaying solitarily or displaying both on leks and solitarily. We found that differences in body size, body condition, fluctuating asymmetry scores, wing coloration, territory location and behaviour (attraction, solicitation and agonistic) did not explain the observed variation in mating tactics used by males. Which males abandoned versus returned to leks was also not related to morphology or behaviour, and there was no tendency for males to join leks that were larger or smaller than the lek they abandoned. These results suggest that male desertion of leks was not dependent on a male's characteristics nor on the size of the lek he was presently attending. Males did join leks with larger males than their previous lek, perhaps to mate with females attracted to these larger 'hotshot' males. Males at both leks and solitary sites successfully mated. Lek tenure did not affect mating success, although lekking males appeared to mate more frequently than solitary males. Courtship disruption and to a lesser extent, female mimicry, were effective at preventing females from mating at leks, and may offer a partial explanation for female mating off leks. Our analysis that combined all males together within a year (regardless of mating tactic) indicated that males that attended leks for longer periods of time and that had fewer wing spots were significantly more likely to mate. Given some evidence that wing spotting declines with age, and that females inspect male underwings during courtship, the latter result suggests that female choice may play some role in determining male success. We suggest that male buff-breasted sandpipers may use alternative mating tactics more readily than males in other 'classic' lek-breeding species because: (1) unpredictable breeding conditions in this species' high

Courtship disruption and to a lesser extent, female mimicry, were effective at preventing females from mating at leks, and may offer a partial explanation for female mating off leks. Our analysis that combined all males together within a year (regardless of mating tactic) indicated that males that attended leks for longer periods of time and that had fewer wing spots were significantly more likely to mate. Given some evidence that wing spotting declines with age, and that females inspect male underwings during courtship, the latter result suggests that female choice may play some role in determining male success. We suggest that male buff-breasted sandpipers may use alternative mating tactics more readily than males in other 'classic' lek-breeding species because: (1) unpredictable breeding conditions in this species' high

    Full Text Available The aim of the study is to establish the structure of the technical and tactical actions skilled players with a specific game role and areas of the field. Found that the improvement of the technical and tactical actions must be due to functional responsibilities of the players depending on the game role and the different areas of the playing field. Found that the most involved areas on average during the match falls on the linebackers, and the lowest - in the forwards. The last defenders and midfielders mainly perform the technical and tactical actions in the flanking regions, and the central axis of the players - in the central areas of the field. The obtained data confirmed that modern football is important players perform functional duties in accordance with their roles and areas of the field. Differentiated approach is recommended in the process of improving the technical and tactical training of players.

    2011-01-01

    Full Text Available An integrated equilibrium model for tactical decisions in network design is developed. We consider a decentralized supply chain network operating in markets under uncertain demands when there is a rival decentralized chain. The primary assumption is that two chains provide partial substitutable products to the markets, and markets' demands are affected by tactical decisions such as price, service level, and advertising expenditure. Each chain consists of one risk-averse manufacturer and a set of risk-averse retailers. The strategic decisions are frequently taking precedence over tactical ones. Therefore, we first find equilibrium of tactical decisions for each possible scenario of supply chain network. Afterwards, we find optimal distribution network of the new supply chain by the scenario evaluation method. Numerical example, including sensitivity analysis will illustrate how the conservative behaviors of chains' members affect expected demand, profit, and utility of each distribution scenario.

    Full Text Available Aim. The aim of the researches was to inspect the relation between borderline personality and Machiavellianism as well as the tendency to apply various manipulation tactics in everyday life and in therapy.Method. The test used an original/ authors’ survey for testing the tendency to employ manipulation tactics as well as a MACH-IV questionnaire (Christie, Geis, 1970 for measuring Machiavellianism. The studied group included 30 patients with diagnosed BPD, 37 therapists and 30 persons in the control group.Results. No differences were noted in the general indicator of Machiavellianism; however, the patients scored lower on the Tactics scale than people from the control group. Patients preferred employing the tactics of taking offense, lying and begging in everyday life. Compared to people from the control group, patients presented a larger tendency to employ tactics of begging, threatening and threatening to break off a close relationship, and a lower tendency to employ seduction. According to therapists, during the therapy patients most often resorted to lying and arousing guilt. Therapists assessed the patients’ tendency to employ manipulation tactics higher than the patients themselves.

    2017-01-01

    Impression management (IM) is pervasive in interview and job performance settings. We meta-analytically examine IM by self- and other-focused tactics to establish base rates of tactic usage, to understand the impact of tactics on interview and job performance ratings, and to examine the moderating effects of research design. Our results suggest IM is used more frequently in the interview rather than job performance settings. Self-focused tactics are more effective in the interview rather than in job performance settings, and other-focused tactics are more effective in job performance settings rather than in the interview. We explore several research design moderators including research fidelity, rater, and participants. IM has a somewhat stronger impact on interview ratings in lab settings than field settings. IM also has a stronger impact on interview ratings when the target of IM is also the rater of performance than when the rater of performance is an observer. Finally, labor market participants use IM more frequently and more effectively than students in interview settings. Our research has implications for understanding how different IM tactics function in interview and job performance settings and the effects of research design on IM frequency and impact.

That project, to plant 52 million trees, protect existing forests from cutting and fire, and enhance rural development, is being implemented by CARE Guatemala to offset 120 per cent of the emissions of a small coal burning power plant that has been built in Connecticut. Since that time, several utilities and governments have initiated additional projects. Not all of these necessarily consist of tree planting in other countries, but may consist of energy efficiency or energy conservation programs designed to reduce carbon emissions by at least as much as the additional releases from a new facility. All JI projects share the characteristic of linking the release of greenhouse gases in an industrial country with an offset that reduces or absorbs a comparable amount in another country. The emitter in the industrial country is willing to pay for the reduction elsewhere because costs are less than they would be at home.

    2017-06-14

    The miniaturization of machines towards the micron and nanoscale requires the development of joint-like elements that enable and constrain motion. We present a facile method to create colloidal joints, that is, anisotropic colloidal particles functionalized with surface mobile DNA linkers that control the motion range of bonded particles. We demonstrate quantitatively that we can control the flexibility of these colloidal joints by tuning the DNA linker concentration in the bond area. We show that the shape of the colloidal joint controls the range of motion of bonded particles through a maximisation of the bond area. Using spheres, cubes, and dumbbells, we experimentally realize spherical joints, planar sliders, and hinges, respectively. Finally we demonstrate the potential of the colloidal joints for programmable bottom-up self-assembly by creating flexible colloidal molecules and colloidal polymers. The reconfigurability and motion constraint offered by our colloidal joints make them promising building blocks for the development of switchable materials and nanorobots.

  18. Using an inflation-augmented price-earnings ratio to guide tactical asset allocation

    2011-08-01

    Full Text Available Asset allocation plays a central role in determining investment outcomes, and available evidence shows that portfolio results can be enhanced through tactical asset allocation if managers use the simple price-earnings ratio as a predictor of equity returns. Recently, some international evidence has emerged which shows that, by augmenting the price-earnings metric with information about consumer price inflation, further enhancements can be achieved in tactical asset allocation.  This study reviews these arguments  as they apply to South Africa, and finds that an inflation-augmented price-earnings ratio is more successful in forecasting equity returns than is the simple price-earnings ratio.  Moreover, the metric is found to be significant in explaining relative asset class returns. On a risk-adjusted basis, however, the tool fails to improve the portfolio results when compared to a buy-and-hold strategy.

The more the level of relationship marketing tactics, the more the quality of relations with customers, which ultimately leads to customer loyalty.

  20. Tactical UAV Localization Using Coordinated Monopulse Trackers with Low Rate Feedback

    2013-07-01

    Full Text Available To run a tactical unmanned aerial vehicle (UAV, efficient information transmission schemes, such as beamforming, are preferred due to the limit of the payload. Therefore, beam tracking and localization algorithms are considered to be one of the key technologies. In this paper, we propose a coordinated UAV localization algorithm for a tactical scenario where the ground receivers are connected with wireless limited lower rate backhaul and are closely spaced. By applying the αβ filter to the conventional scheme, we first show that the localization performance can be improved significantly. We also propose an efficient localization algorithm for a system with low rate limited feedback. Using numerical simulations, we show that the proposed scheme can improve the localization performance while reducing the feedback over conventional scheme.

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

    Brown, Culum; Garwood, Martin P; Williamson, Jane E

    2012-10-23

    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.

    Previous talks at this meeting have covered our collaborative work on high-energy jets such as present in tactical aircraft (those with supersonic plumes). The emphasis of this work is improving our understanding of flow physics and our prediction tools. In this presentation we will discuss recent flow diagnostics acquired using Particle Image Velocimetry (PIV) made on an underexpanded shocked jet plume from a tactical aircraft nozzle. In this presentation we show cross-sectional and streamwise cuts of both mean and turbulent velocities of an F404 engine nozzle with various chevron designs applied. The impact of chevron penetration, length, and width are documented. The impact of the parameters is generally nonlinear in measures considered here, a surprising result given the relatively smooth behavior of the noise to variations in these chevron parameters.

    Batzias, Dimitris F.; Pollalis, Yannis A.

    2012-12-01

    In this paper, optimal environmental policy for reclamation of land unearthed in lignite mines is defined as a strategic target. The tactics concerning the achievement of this target, includes estimation of optimal time lag between each lignite site (which is a segment of the whole lignite field) complete exploitation and its reclamation. Subsidizing of reclamation has been determined as a function of this time lag and relevant implementation is presented for parameter values valid for the Greek economy. We proved that the methodology we have developed gives reasonable quantitative results within the norms imposed by legislation. Moreover, the interconnection between strategy and tactics becomes evident, since the former causes the latter by deduction and the latter revises the former by induction in the time course of land reclamation.

    Full Text Available This case study examines the incorporation of digital media technologies and practices into Respecting Elders: Communities Against elder Abuse (RECAA, an organization of activist elders. By studying RECAA’s specific transition and following the work of Michel de Certeau (1988, I distinguish between tactical mediatization and strategic mediatization. Organizations such as RECAA must negotiate with political, ideological, administrative, and economic agendas that exert pressure and provide incentives for organizations “to mediatize” in order to survive in the current Canadian context. ‘Tactical mediatization’ is used to understand RECAA’s very deliberate and considered response to these pressures. This distinction provides a framework for conceptualizing how activist organizations such as RECAA struggle to exert agency within meta-processes that place mounting and insistent pressure on the organization to incorporate digital media technologies into its mandate and system of values.

    Multiple Input Multiple Output (MIMO) wireless communications vastly expand the capacity and connectivity of communications for forces operating in challenging environments such as urban or forested terrain. A MIMO architecture called BLAST (Bell Laboratories Layered Space-Time) has been formulated to realize these capacities. We have developed a packet version of BLAST, called PacketBLAST, specifically to support high mobility, ad-hoc, tactical communications on the move in challenging environments. PacketBLAST offers a number of benefits to tactical communications. We have implemented a first-ever, end-to-end mobile, ad-hoc network (MANET) of PacketBLAST nodes and have successfully tested it in a number of field demonstrations.

    The Night Vision Goggle (NVG) Tactical Decision Aid (TDA) was developed to support Army operations in situations requiring accurate predictions of light levels. Minimum thresholds of illumination are used by the Army to plan and execute missions during periods of darkness or near darkness. The NVG TDA is part of a suite of decision aids that will become part of the fielded Integrated Meteorological System (IMETS). The IMETS is a system designed to be operated by Air Force Staff Weather Officers supporting Army tactical operations in peacetime and in times of conflict. The verification and validation (V & V) effort discussed in this report is part of the Battlefield Environment Directorate configuration management plan to field physically correct and user-friendly software to Army units over the entire conflict spectrum. The V & V described is thorough and shows that the NVG TDA is physically correct and applicable for accreditation before use.

    It is the intent of this article to define the strategy by which Combat Medics have been employed in contemporary stability operations and counterinsurgency conflicts. This article describes the advances in training based on Tactical Combat Casualty Care and how training evolved into an evidence-based model. Training platforms evolved with shifts in mission requirements, new technology, improved medical techniques, and changing protocols. The last portion of this article details recommendations in doctrine, materiel, and training that could enable optimal sustainment standards while retaining operational capability across a wide variety of combat and peace operations. Lessons learned and changes adapted for Medics that are addressed: (1) advances in training and employment of the Combat Medic necessitated by tactics and strategy of current conflicts, (2) Combat Medic regulatory requirements and centralized, just-in-time training, and (3) changes in sustainment training driven by certification requirements and use of medical simulation training centers.

    Tactical mobile ad hoc network (MANET) is a collection of mobile nodes forming a temporary network,without the aid of pre-established network infrastructure. The routing protocol has a crucial impact on the networkperformance in battlefields. Link reliability based hybrid routing (LRHR) is proposed, which is a novel hybrid routing protocol, for tactical MANET. Contrary to the traditional single path routing strategy, multiple paths are established between a pair of source-destination nodes. In the hybrid routing strategy, the rate of topological change provides a natural mechanism for switching dynamically between table-driven and on-demand routing. The simulation results indicate that the performances of the protocol in packet delivery ratio, routing overhead, and average end-to-end delay are better than the conventional routing protocol.

The corpus consists of students’ interviews and writing and rewriting texts activities, which were held throughout two disciplines of the course, taught by the same teacher. Data analysis highlights few times when students performed active and tactical attitude in the writing process activities in both disciplines. This result is among other reasons due to the history of each student as a producer of texts in basic education, and above all the absence of a significant work in producing texts in the Languages Graduate Course.

    2015-01-01

    In soccer, home teams win about 67% of decided games. The causes for this home advantage are still unresolved. There is a shortage of research on the psychological states of actors involved. In this study, we examined soccer coaches' expectations, goal setting and tactical decisions in relation to game location. Soccer coaches (N = 297) with different expertise levels participated in an experimental, online management game and were randomly assigned to one of two groups, "home game (HG)" or "away game." Participants received information on the game for which they were asked to make decisions in multiple points. The only differing information between groups was game location. Regardless of expertise, HG coaches had higher expectations to win, set more challenging goals and decided for more offensive and courageous playing tactics. Possible consequences of these findings concerning home advantage in soccer are discussed.

    1984-12-01

    Many hospitals are concerned about the loss of control which is associated with contracting for linen service. On the the hand, many laundries do not have the resources or experience to serve hospitals in a comprehensive and trouble-free manner. In many communities a joint venture, such as the one described here, can successfully combine the interests of the hospital and laundry communities without causing the hospitals to lose control of the service and without requiring the laundry operator to have detailed knowledge of hospital operations. As more hospitals opt for contract service, and if this service is to be provided at the lowest total cost, the hospitals and the laundries must come to grips with the problems surrounding the laundry-hospital interface. A joint venture, such as that described here, is one way to accomplish this.
