  8. Natural games

    CERN Document Server

    Anttila, Jani

    2011-01-01

    Behavior in the context of game theory is described as a natural process that follows the 2nd law of thermodynamics. The rate of entropy increase as the payoff function is derived from statistical physics of open systems. The thermodynamic formalism relates everything in terms of energy and describes various ways to consume free energy. This allows us to associate game theoretical models of behavior to physical reality. Ultimately behavior is viewed as a physical process where flows of energy naturally select ways to consume free energy as soon as possible. This natural process is, according to the profound thermodynamic principle, equivalent to entropy increase in the least time. However, the physical portrayal of behavior does not imply determinism. On the contrary, evolutionary equation for open systems reveals that when there are three or more degrees of freedom for behavior, the course of a game is inherently unpredictable in detail because each move affects motives of moves in the future. Eventually, wh...

  9. ["Treasure Hunt"--a cognitive-behavioural computer game].

    Brezinka, Veronika

    2011-01-01

    The development of video games promoting health related behaviour is increasing. This holds not only for chronic diseases like asthma and diabetes, but also for the field of child psychotherapy. At the Department of Child and Adolescent Psychiatry of Zürich University, the video game Treasure Hunt was developed to support psychotherapeutic treatment of children between eight and thirteen years of age. Treasure Hunt does not replace the therapist but supports treatment by offering attractive electronic work assignments. The scope of this article is an overview on health games for children and a description of Treasure Hunt. After the explanation of its therapeutic potentials, an evaluation based on questionnaires for therapists and children will be presented. 124 therapists answered a questionnaire on their impression of the game three months after download. 41 therapists were willing to participate in the further evaluation and sent questionnaires of 200 children with whom Treasure Hunt had been used. A limitation of these data is that a positive bias can not be excluded, as therapists with a positive attitude towards psychotherapeutic computer games were more likely to answer the questionnaire. 118 therapists (95.2%) considered Treasure Hunt a useful tool in child psychotherapy. 197 children (98.5%) report being satisfied with the use of the game during treatment. Treasure Hunt was predominantly used for the age group it is designed for and both, by very experienced and by young therapists. Eleven diagnostic categories reflect a broader range of indications than expected.

    In this paper I quantize the stag hunt game in the framework proposed by Marinatto and Weber which, is introduced to quantize the Battle of the Sexes game and gives a general quntization scheme of various game theories. Then I discuss the Nash equibilium solution in the cases of which starting strategies are taken in both non entangled state and entangled state and uncover the structure of Nash Equilibrium solutions and compare the case of the Battle of the Sexes game. Since the game has 4 parameters in the payoff matrix has rather rich structure than the Battle of the Sexes game with 3-parameters in the payoff matrix, the relations of the magnitude of these payoff values in Nash Equilibriums are much involuved. This structure is uncovered completly and it is found that the best strategy which give the maximal sum of the payoffs of both players strongly depends on the initial quntum state. As the bonus of the formulation the stag hunt game with four parameters we can discuss various types of symmetric games p...

  1. Provisioning of game meat to rural communities as a benefit of sport hunting in Zambia.

    White, Paula A; Belant, Jerrold L

    2015-01-01

    Sport hunting has reportedly multiple benefits to economies and local communities; however, few of these benefits have been quantified. As part of their lease agreements with the Zambia Wildlife Authority, sport hunting operators in Zambia are required to provide annually to local communities free of charge i.e., provision a percentage of the meat obtained through sport hunting. We characterized provisioning of game meat to rural communities by the sport hunting industry in Zambia for three game management areas (GMAs) during 2004-2011. Rural communities located within GMAs where sport hunting occurred received on average > 6,000 kgs per GMA of fresh game meat annually from hunting operators. To assess hunting industry compliance, we also compared the amount of meat expected as per the lease agreements versus observed amounts of meat provisioned from three GMAs during 2007-2009. In seven of eight annual comparisons of these GMAs, provisioning of meat exceeded what was required in the lease agreements. Provisioning occurred throughout the hunting season and peaked during the end of the dry season (September-October) coincident with when rural Zambians are most likely to encounter food shortages. We extrapolated our results across all GMAs and estimated 129,771 kgs of fresh game meat provisioned annually by the sport hunting industry to rural communities in Zambia at an approximate value for the meat alone of >US$600,000 exclusive of distribution costs. During the hunting moratorium (2013-2014), this supply of meat has halted, likely adversely affecting rural communities previously reliant on this food source. Proposed alternatives to sport hunting should consider protein provisioning in addition to other benefits (e.g., employment, community pledges, anti-poaching funds) that rural Zambian communities receive from the sport hunting industry.

    2012-01-01

    Studies suggest hunter discarded viscera of big game animals (i.e., offal) is a source of lead available to scavengers. We investigated the incidence of lead exposure in bald eagles in Wyoming during the big game hunting season, the influx of eagles into our study area during the hunt, the geographic origins of eagles exposed to lead, and the efficacy of using non-lead rifle ammunition to reduce lead in eagles. We tested 81 blood samples from bald eagles before, during and after the big game hunting seasons in 2005-2010, excluding 2008, and found eagles had significantly higher lead levels during the hunt. We found 24% of eagles tested had levels indicating at least clinical exposure (>60 ug/dL) during the hunt while no birds did during the non-hunting seasons. We performed driving surveys from 2009-2010 to measure eagle abundance and found evidence to suggest that eagles are attracted to the study area during the hunt. We fitted 10 eagles with satellite transmitters captured during the hunt and all migrated south after the cessation of the hunt. One returned to our study area while the remaining nine traveled north to summer/breed in Canada. The following fall, 80% returned to our study area for the hunting season, indicating that offal provides a seasonal attractant for eagles. We fitted three local breeding eagles with satellite transmitters and none left their breeding territories to feed on offal during the hunt, indicating that lead ingestion may be affecting migrants to a greater degree. During the 2009 and 2010 hunting seasons we provided non-lead rifle ammunition to local hunters and recorded that 24% and 31% of successful hunters used non-lead ammunition, respectively. We found the use of non-lead ammunition significantly reduced lead exposure in eagles, suggesting this is a viable solution to reduce lead exposure in eagles.

  7. Lead exposure in free-flying turkey vultures is associated with big game hunting in California.

    Directory of Open Access Journals (Sweden)

    Terra R Kelly

    Full Text Available Predatory and scavenging birds are at risk of lead exposure when they feed on animals injured or killed by lead ammunition. While lead ammunition has been banned from waterfowl hunting in North America for almost two decades, lead ammunition is still widely used for hunting big game and small game animals. In this study, we evaluated the association between big game hunting and blood lead concentration in an avian scavenger species that feeds regularly on large mammals in California. We compared blood lead concentration in turkey vultures within and outside of the deer hunting season, and in areas with varying wild pig hunting intensity. Lead exposure in turkey vultures was significantly higher during the deer hunting season compared to the off-season, and blood lead concentration was positively correlated with increasing wild pig hunting intensity. Our results link lead exposure in turkey vultures to deer and wild pig hunting activity at these study sites, and we provide evidence that spent lead ammunition in carrion poses a significant risk of lead exposure to scavengers.

  12. Coordination learning in stag hunt games with application to emergency management.

    Science.gov (United States)

    Guastello, Stephen J; Bond Jr, Robert W

    2004-07-01

    Response teams for natural disaster emergencies require coordinated and self-organized efforts for rescue, medical services, damage containment, and evacuation. The unfolding of events depends on initial conditions of specific time, location, and preparedness of the response teams. This study considered a new range of emergency response situations where the perpetrator is a sentient attacker that learns with repeated exchanges. The strategy is conceptualized as a stag hunt coordination game on the part of the defense agents and a strictly competitive game with respect to the attacking adversary. Participants were 28 university students who played an iterative board game (The Creature that Ate Sheboygan) wherein a team of three Humans represented military and civil resources, against one Godzilla-type monster. The Monster gained points by destroying buildings and human combat power. The Humans gained points by wearing down the Monster's defenses and containing damage caused by the Monster. Experimental manipulations and empirical analysis showed the following: Communication outages among the Humans assisted the Monster, but the ability to communicate only equalized the Humans' chances rather than providing them with an advantage. Coordination among Humans was instant, but it fluctuated greatly as a result of the Monster's progress. Nonlinear analysis showed an asymptotic decline in coordination to a non-zero level in response to outcome uncertainty. Learning effects were noted for Humans and Monsters, but there were significant interactions with communication blackout conditions

    Full Text Available Knowing the profileof hunting tourism consumers is particularly useful to the administrators ofhunting funds or natural parks, and of travel agencies that develop huntingtourism products for the hunting of large game for trophy, of small game asrecreational activity and also for the experienced hunting tourists who loveadventure and hunting with traditional weapons. The motivation for huntingconsists in the existing fauna in a certain area, but there are also cultural,historical reasons or spending time in the middle of nature. Consumers ofhunting tourism have a wide range of ages: hunting tourists prefer watching theanimals in their natural habitat and are less adventure-oriented, unlike trophyhunting tourists who are self-contended, travel much and wish to know thehistory, the culture and the behaviour of animals in protected areas. Theyprefer special accommodation and transport conditions and rely on largeincomes: they wish to get the rarest trophies to display back home as a symbolof their hunting skills and courage

    Development from extracting oil and gas resources can have unintended effects on multiple ecosystem functions, with cascading effects on wildlife, ecosystem services, and local economies. Big-game hunting opportunities may be closely related to these effects, but empirical analyses of impacts of energy development on hunting are limited. We examined the influence of oil and gas development density on harvest efficiency, or harvest per unit of hunter effort, within all hunt areas in Wyoming, USA, from 2008 to 2014 for 3 big-game species: elk (Cervus canadensis), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana). Using harvest/hunter day as the response variable, we compared linear mixed-effects models for each species that included total well density (i.e., all wells constructed up to the year of record), active well density (i.e., only those wells currently producing oil or gas in that year), or neither as a predictor variable. We used well densities as indicators of development in the absence of data specifying the locations of other oil and gas infrastructure (e.g., roads, well pads). Models also accounted for the fixed effects of road density, hunter density, proportion of the area that is public land with unrestricted hunter access, proportion of the area that is forested, year of observation, and random effects of variation among hunt areas nested within associated game herd units. Presence of oil and gas wells had a positive influence on harvest efficiency for elk and mule deer. Although there was no overall effect to pronghorn, there was a negative influence of wells on juvenile pronghorn harvest efficiency. Changes in harvest efficiency due to expanding oil and gas development could alter the time spent hunting by hunters and their chances of harvesting an animal. This could have subsequent impacts on hunter satisfaction, game populations, and economic revenue generated from recreational hunters.

    Full Text Available Skin whitening products are commercially available for cosmetic purposes in order to obtain a lighter skin appearance. They are also utilized for clinical treatment of pigmentary disorders such as melasma or postinflammatory hyperpigmentation. Whitening agents act at various levels of melanin production in the skin. Many of them are known as competitive inhibitors of tyrosinase, the key enzyme in melanogenesis. Others inhibit the maturation of this enzyme or the transport of pigment granules (melanosomes from melanocytes to surrounding keratinocytes. In this review we present an overview of (natural whitening products that may decrease skin pigmentation by their interference with the pigmentary processes.

  5. Treasure Hunt - a serious game to support psychotherapeutic treatment of children.

    2008-01-01

    Computer and video games for children have gained negative publicity due to reported associations between intensive gaming and aggressive behaviour, school failure, and overweight. While most studies centre upon negative consequences of video games, their innovative potentials tend to be overlooked. One field for the innovative use of computer games is child psychotherapy. By including therapeutic concepts into a video game, children can be offered attractive electronic homework assignments that enable them to rehearse and repeat basic psychoeducational concepts they have learned during therapy sessions. Moreover, therapeutic games can help therapists to structure therapy sessions. Psychotherapeutic computer games translated into foreign languages could form a useful tool in the treatment of migrant children. 'Treasure Hunt' is the first serious game based on principles of cognitive behaviour modification. It is developed for eight to twelve year old children who are in cognitive-behavioural treatment for various disorders. Reactions of children and therapists to experimental versions of the game are positive. Serious games might prove a useful tool to support psychotherapeutic treatment of children.

    2015-04-01

    This posterdescribes a geoscience activities on mineral resources for students of 14-18 years old. The activities are created as a treasure hunt of mineral resources, students must pass test and solve questions, search mineral in different environments: near a volcanos, in the river, in a lake, in a cave, under the sea and on a mountain. The activity is created using a virtual environment a virtual world built with a software, Opensim, a opensource software. In this virtual world every student as avatar, a virtual rapresentation of himself, search information, objects, mineral as in a serious game, a digital serious game. In the serious game buit as a treasure hunt, students interact with environment in a learning by doing, and they interact with other students in a cooperative learning and a collaborative environment. In the hunt there is a challenge that student must overcome: understanding what is a mineral resource collecting data on mineral analyzing environments where they are created so the students can improve motivation and learn, and improve scientific skills.

  10. How hunting strengthens social awareness of coupled human-natural systems

    Directory of Open Access Journals (Sweden)

    M. Nils Peterson

    2010-12-01

    Full Text Available Hunting has the potential to remind modern societies of their reliance on natural systems. As a material and symbolic practice that motivates both hunters and non-hunters to certain actions relative to nature, hunting enables society to experience itself and nature differently than it could if humans no longer hunted. Although hunting may be anachronistic in modern society, certain dimensions of hunting culture may enable society to re-collect a sense of human integration with nature. In this essay, we develop a critical perspective grounded in neo-Marxist and Durkheimian theory to analyze how hunting may contribute to linking humans and nature by rendering the materiality of food production explicit, and how hunting culture strengthens the symbolic meaning of food in ways that are rooted in its materiality. We trace this potential through the practices of searching, killing, processing, and consuming food obtained via hunting. Along the way, we note how technology, both formal and informal social control, and commoditization may constrain hunting’s potential to highlight linkages between human and natural systems.

  2. Will Hunting Wildlife Harm the Ecological Balance of Nature?

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    The Expert Committee of Wild Animal Hunting,an organization under the State Forestry Administration of China,recently approved a group of foreign hunters’applications to shoot wildlife in China. The news has gained much attention across the country. The application was submitted by two domestic travel agencies on behalf of seven foreign hunters,who plan to shoot nine blue sheep and seven Tibetan gazelles in an international hunting ground in west China’s Qinghai Province. Despite the expert committee’s approval,however,the hunters still can’t fire a shot in China until they get an official license from the State Forestry Administration.According to recent news,the administration has declined the application. In China,blue sheep and Tibetan gazelles are ranked as Class 2

  3. Cooperative behavior and phase transitions in co-evolving stag hunt game

    2016-02-01

    Cooperative behavior and different phases in a co-evolving network dynamics based on the stag hunt game is studied. The dynamical processes are parameterized by a payoff r that tends to promote non-cooperative behavior and a probability q for a rewiring attempt that could isolate the non-cooperators. The interplay between the parameters leads to different phases. Detailed simulations and a mean field theory are employed to reveal the properties of different phases. For small r, the cooperators are the majority and form a connected cluster while the non-cooperators increase with q but remain isolated over the whole range of q, and it is a static phase. For sufficiently large r, cooperators disappear in an intermediate range qL ≤ q ≤qU and a dynamical all-non-cooperators phase results. For q >qU, a static phase results again. A mean field theory based on how the link densities change in time by the co-evolving dynamics is constructed. The theory gives a phase diagram in the q- r parameter space that is qualitatively in agreement with simulation results. The sources of discrepancies between theory and simulations are discussed.

    2016-08-01

    Full Text Available Background: Indigenous peoples have traditionally relied on foods hunted and gathered from their immediate environment. The Eastern James Bay Cree people consume wild game and birds, and these are believed to provide health as well as cultural benefits. Objective: To determine the fatty acid (FA composition of traditional game and bird meats hunted in the Eastern James Bay area. Design: Harvested traditional game and birds were analysed for FA composition. A total of 52 samples from six wildlife species were collected in the areas of Chisasibi, Waswanipi and Mistissini, of which 35 were from birds (white partridge and Canada goose and 17 were from land animals (beaver, moose, caribou and black bear. Results: Alpha-linolenic acid (ALA was the most common n-3 polyunsaturated fatty acid (PUFA in all samples except for the black bear flesh, in which it was docosapentaenoic acid (DPAn-3. In white partridge, beaver and caribou flesh, PUFAs (mainly n-6 were the most common category of fats while in goose, moose and black bear flesh, monounsaturated fatty acids (MUFAs predominated. In all species, saturated fatty acids (SFAs were the second most important FAs. It would appear that in the land animals and birds that were analysed, the SFA content was lower and the PUFA content was higher than store-bought meats giving them a more heart-healthy profile. Conclusions: These results showed that the FA composition of game species consumed by the James Bay Cree population is consistent with a beneficial diet and that traditional foods should continue to be promoted among the Cree people to provide better physical health as well as social and spiritual benefits.

    Full Text Available This project shows a creative approach to the familiar scavenger hunt game. It involved the implementation of an iPhone application, HUNT, with Augmented Reality (AR capability for the users to play the game as well as an administrative website that game organizers can use to create and make available games for users to play. Using the HUNT mobile app, users will first make a selection from a list of games, and they will then be shown a list of objects that they must seek. Once the user finds a correct object and scans it with the built-in camera on the smartphone, the application will attempt to verify if it is the correct object and then display associated multi-media AR content that may include images and videos overlaid on top of real world views. HUNT not only provides entertaining activities within an environment that players can explore, but the AR contents can serve as an educational tool. The project is designed to increase user involvement by using a familiar and enjoyable game as a basis and adding an educational dimension by incorporating AR technology and engaging and interactive multimedia to provide users with facts about the objects that they have located

  14. Applying principles from the game theory to acute stroke care: Learning from the prisoner's dilemma, stag-hunt, and other strategies.

    Science.gov (United States)

    Saposnik, Gustavo; Johnston, S Claiborne

    2016-04-01

    Acute stroke care represents a challenge for decision makers. Decisions based on erroneous assessments may generate false expectations of patients and their family members, and potentially inappropriate medical advice. Game theory is the analysis of interactions between individuals to study how conflict and cooperation affect our decisions. We reviewed principles of game theory that could be applied to medical decisions under uncertainty. Medical decisions in acute stroke care are usually made under constrains: short period of time, with imperfect clinical information, limit understanding about patients and families' values and beliefs. Game theory brings some strategies to help us manage complex medical situations under uncertainty. For example, it offers a different perspective by encouraging the consideration of different alternatives through the understanding of patients' preferences and the careful evaluation of cognitive distortions when applying 'real-world' data. The stag-hunt game teaches us the importance of trust to strength cooperation for a successful patient-physician interaction that is beyond a good or poor clinical outcome. The application of game theory to stroke care may improve our understanding of complex medical situations and help clinicians make practical decisions under uncertainty. © 2016 World Stroke Organization.

    2012-04-01

    City are looked for today, including a development at the University of Torino called SimTorino, which simulates the development of the city in the next 20 years. The connection to another games genre as video games, the board games, will be investigated, since there are games on construction and reconstruction of a cathedral and its tower and a bridge in an urban environment of the middle ages based on the two novels of Ken Follett, "Pillars of the Earth" and "World Without End" and also more recent games, such as "Urban Sprawl" or the Romanian game "Habitat", dealing with the man-made hazard of demolition. A review of these games will be provided based on first hand playing experience. In games like "World without End" or "Pillars of the Earth", just like in the recently popular games of Zynga on social networks, construction management is done through providing "building" an item out of stylised materials, such as "stone", "sand" or more specific ones as "nail". Such approach could be used also for retrofitting buildings for earthquakes, in the series of "upgrade", not just for extension as it is currently in games, and this is what our research is about. "World without End" includes a natural disaster not so analysed today but which was judged by the author as the worst of manhood: the Black Death. The Black Death has effects and costs as well, not only modelled through action cards, but also on the built environment, by buildings remaining empty. On the other hand, games such as "Habitat" rely on role playing, which has been recently recognised as a way to bring games theory to decision making through the so-called contribution of drama, a way to solve conflicts through balancing instead of weighting, and thus related to Analytic Hierarchy Process. The presentation aims to also give hints on how to design a game for the problem of earthquake retrofit, translating the aims of the actors in such a process into role playing. Games are also employed in teaching of urban

    2016-01-01

    Full Text Available Natural User Interface (NUI is a new approach that has become increasingly popular in Human-Computer Interaction (HCI. The use of this technology is widely used in almost all sectors, including the field of education. In recent years, there are a lot of educational games using NUI technology in the market such as Kinect game. Kinect is a sensor that can recognize body movements, postures, and voices in three dimensions. It enables users to control and interact with game without the need of using game controller. However, the contents of most existing Kinect games do not follow the standard curriculum in classroom, thus making it do not fully achieve the learning objectives. Hence, this research proposes a design model as a guideline in designing educational game using NUI. A prototype has been developed as one of the objectives in this study. The prototype is based on proposed model to ensure and assess the effectiveness of the model. The outcomes of this study conclude that the proposed model contributed to the design method for the development of the educational game using NUI. Furthermore, evaluation results of the prototype show a good response from participant and in line with the standard curriculum.

  20. Names for Games: Locating 2 × 2 Games

    Directory of Open Access Journals (Sweden)

    Bryan Randolph Bruns

    2015-10-01

    Full Text Available Prisoner’s Dilemma, Chicken, Stag Hunts, and other two-person two-move (2 × 2 models of strategic situations have played a central role in the development of game theory. The Robinson–Goforth topology of payoff swaps reveals a natural order in the payoff space of 2 × 2 games, visualized in their four-layer “periodic table” format that elegantly organizes the diversity of 2 × 2 games, showing relationships and potential transformations between neighboring games. This article presents additional visualizations of the topology, and a naming system for locating all 2 × 2 games as combinations of game payoff patterns from the symmetric ordinal 2 × 2 games. The symmetric ordinal games act as coordinates locating games in maps of the payoff space of 2 × 2 games, including not only asymmetric ordinal games and the complete set of games with ties, but also ordinal and normalized equivalents of all games with ratio or real-value payoffs. An efficient nomenclature can contribute to a systematic understanding of the diversity of elementary social situations; clarify relationships between social dilemmas and other joint preference structures; identify interesting games; show potential solutions available through transforming incentives; catalog the variety of models of 2 × 2 strategic situations available for experimentation, simulation, and analysis; and facilitate cumulative and comparative research in game theory.

  3. Learning the Rules of the Game: The Nature of Game and Classroom Supports When Using a Concept-Integrated Digital Physics Game in the Middle School Science Classroom

    Science.gov (United States)

    Stewart, Phillip Michael, Jr.

    Games in science education is emerging as a popular topic of scholarly inquiry. The National Research Council recently published a report detailing a research agenda for games and science education entitled Learning Science Through Computer Games and Simulations (2011). The report recommends moving beyond typical proof-of-concept studies into more exploratory and theoretically-based work to determine how best to integrate games into K-12 classrooms for learning , as well as how scaffolds from within the game and from outside the game (from peers and teachers) support the learning of applicable science. This study uses a mixed-methods, quasi-experimental design with an 8th grade class at an independent school in southern Connecticut to answer the following questions: 1. What is the nature of the supports for science content learning provided by the game, the peer, and the teacher, when the game is used in a classroom setting? 2. How do the learning gains in the peer support condition compare to the solo play condition, both qualitatively and quantitatively? The concept-integrated physics game SURGE (Scaffolding Understanding through Redesigning Games for Education) was selected for this study, as it was developed with an ear towards specific learning theories and prior work on student understandings of impulse, force, and vectors. Stimulated recall interviews and video observations served as the primary sources and major patterns emerged through the triangulation of data sources and qualitative analysis in the software QSR NVivo 9. The first pattern which emerged indicated that scaffolding from within the game and outside the game requires a pause in game action to be effective, unless that scaffolding is directly useful to the player in the moment of action. The second major pattern indicated that both amount and type of prior gaming experience has somewhat complex effects on both the uses of supports and learning outcomes. In general, a high correlation was found

  5. How much land is needed for feral pig hunting in Hawai'i?

    Science.gov (United States)

    Hess, Steven C.; Jacobi, James D.

    2014-01-01

    Hunting is often considered to be incompatible with conservation of native biota and watershed functions in Hawai'i. Management actions for conservation generally exclude large non-native mammals from natural areas, thereby reducing the amount of land area available for hunting activities and the maintenance of sustainable game populations. An approach which may be useful in addressing the necessary minimum amount of land area allocated for hunting in Hawai'i is to determine the amount of land area necessary for sustaining populations of hunted animals to meet current levels harvested by the public. We ask: What is the total amount of land necessary to provide sustained-yield hunting of game meat for food at the current harvest level on Hawai'i Island if only feral pigs (Sus scrofa) were to be harvested? We used a simplistic analysis to estimate that 1 317.6 km2-1 651.4 km2 would be necessary to produce 187 333.6 kg of feral pig meat annually based on the range of dressed weight per whole pig, the proportion of a pig population that can be sustainably removed annually, and the density of pig populations in the wild. This amount of area comprises 12.6-15.8% of the total land area of Hawai'i Island, but more likely represents 27.6-43.5% of areas that may be compatible with sustained-yield hunting.

    Full Text Available In the last decades, Natural Language Processing (NLP has obtained a high level of success. Interactions between NLP and Serious Games have started and some of them already include NLP techniques. The objectives of this paper are twofold: on the one hand, providing a simple framework to enable analysis of potential uses of NLP in Serious Games and, on the other hand, applying the NLP framework to existing Serious Games and giving an overview of the use of NLP in pedagogical Serious Games. In this paper we present 11 serious games exploiting NLP techniques. We present them systematically, according to the following structure:  first, we highlight possible uses of NLP techniques in Serious Games, second, we describe the type of NLP implemented in the each specific Serious Game and, third, we provide a link to possible purposes of use for the different actors interacting in the Serious Game.

    Imposing electroweak scale naturalness constraints (low \\Delta_{EW}) on SUSY models leads to mass spectra characterized by light higgsinos ~100-300 GeV, highly mixed top-squarks and gluinos at the 1-5 TeV scale and allows for m_h ~125 GeV. First and second generation squarks can easily live at the 5-20 TeV scale, thus providing at least a partial solution to the SUSY flavor/CP problems. For such models at the LHC, gluino pair production is followed by cascade decays to t- and b-quark rich final states along with multileptons. The reach of LHC14 with 300 fb^{-1} is computed to be around m_{\\tg} 1.8 TeV. However, the small magnitude of the \\mu-parameter-- a necessary condition for naturalness-- leads to a unique hadronically quite same-sign diboson (W^\\pm W^\\pm) signature from wino pair production. In low \\Delta_{EW} models with unified gaugino masses, this signature yields a somewhat higher reach up to m_{\\tg} 2.1 TeV. The smallness of |\\mu| implies that the ILC should be a higgsino factory in addition to a Hi...

  12. The (De-)evolution of Evolution Games: A Content Analysis of the Representation of Evolution Through Natural Selection in Digital Games

    Leith, Alex P.; Ratan, Rabindra A.; Wohn, Donghee Yvette

    2016-08-01

    Given the diversity and complexity of education game mechanisms and topics, this article contributes to a theoretical understanding of how game mechanisms "map" to educational topics through inquiry-based learning. Namely, the article examines the presence of evolution through natural selection (ENS) in digital games. ENS is a fundamentally important and widely misunderstood theory. This analysis of ENS portrayal in digital games provides insight into the use of games in teaching ENS. Systematic database search results were coded for the three principles of ENS: phenotypic variation, differential fitness, and fitness heritability. Though thousands of games use the term evolution, few presented elements of evolution, and even fewer contained all principles of ENS. Games developed to specifically teach evolution were difficult to find through Web searches. These overall deficiencies in ENS games reflect the inherent incompatibility between game control elements and the automatic process of ENS.

    Full Text Available In the Republic of Croatia, game meat is consumed far less than meat of domestic animals. Yearly game meat consumption amounts to only 0.55 kg per household member. Consumers prefer meat of domestic animals, because it is cheaper, not paying attention to specific nutritive advantages of game meat. A research on the game meat market and consumers’ preferences was carried out on 101 examinees, chosen among inhabitants of Slavonia and Baranja. The majority of questioned inhabitants did consume game meat (92%, of whom 66% consider game meat to be of better quality than meat of domestic animals. Significant number of examinees considers game meat as healthy food, being also convinced that game was healthier to consume if hunted in their natural environment, than if reared on specialized farms (90%. Irrespective of quality, only 22% of examinees buy game meat, and 51% think such meat is too expensive. This is the main reason why consumers have game meat only once a month (51%. Taking into consideration monthly income of their respective household, 58% of examinees can afford game meat only once a month, and, if having an opportunity, they would opt for meat of roe deer (55% and rabbit (25%. When asked what would stimulate the game meat market in Croatia, 56% of examinees believe this could be achieved by lowering of prices, 27% think the issue could be addressed by opening of specialty stores, and only 17% opted for more aggressive marketing activities.

  19. Using systems gaming to explore decision-making under uncertainty in natural hazard crises

    Science.gov (United States)

    McCaughey, Jamie W.; Finnigan, David

    2017-04-01

    Faced with uncertain scientific forecasts of a potential hazard, it is perhaps natural to wait and see. As we wait, uncertainties do decrease, but so do our options to minimise impacts of the hazard. This tradeoff is fundamental to preparing for natural hazards, yet difficult to communicate. Interactive systems gaming is one promising way forward. We are developing in-person interactive games, drawing on role-playing and other table-top scenario exercises in natural hazards, as well as on game-based modeling of complex systems. Our games model an unfolding natural hazard crisis (such as volcanic unrest or an approaching typhoon) as a complex social-physical system. Participants take on the roles of diverse stakeholder groups (including government, scientists, media, farmers, city residents, and others) with differing expertise, responsibilities, and priorities. Interactions among these groups play out in a context of decreasing scientific uncertainty and decreasing options for actions to reduce societal risk. Key design challenges are (1) to engage players without trivialising the real-world context; (2) to provide the right level of guidance for players to navigate the system; and (3) to enable players to face realistic tradeoffs and see realistic consequences of their choices, without feeling frustrated that the game is set up for them to fail. We will first prototype the games with general public and secondary-school participants, then adjust this for specialist groups working in disaster management. We will illustrate participatory systems gaming techniques in our presentation 'A toolkit of systems gaming techniques' in the companion EGU session EOS6: 'Perform! A platform to discuss art & science projects with live presentation'.

  20. Neandertal mobility and large-game hunting: the exploitation of reindeer during the Quina Mousterian at Chez-Pinaud Jonzac (Charente-Maritime, France).

    Neandertals were effective hunters of large ungulates throughout their geographic and temporal ranges. Equipped with this knowledge, researchers in paleoanthropology continue to seek insight on the relationships between hunting and subsistence strategies with other components of the Neandertals' niche, such as mobility, site use, and lithic technology. The Quina Mousterian deposits from the rockshelter site of Chez Pinaud Jonzac (Charente-Maritime, France; hereafter Jonzac) offer an excellent opportunity to pursue these issues. This paper focuses on the extensive and well-preserved skeletal remains of reindeer (Rangifer tarandus) recovered from recent excavations of the site, representing at least 18 individuals that were hunted by Neandertals during the fall through winter. Our zooarchaeological results indicate that all ages of reindeer were hunted but adult individuals predominate. No bias is evident in the comparable frequencies of males and females. These prey were butchered on-site, with abundant evidence of meat filleting and marrow exploitation. In the excavated sample, the absence of hearths and the almost complete lack of burned bones or stones suggest that Neandertals were not using fire to assist with processing the reindeer carcasses. The zooarchaeological results presented here indicate that reindeer were hunted during a restricted window of time when they were seasonally abundant in the local area near Jonzac. Taken together with the lithic industry based on bifacial elements, the evidence is consistent with a pattern of site use by highly mobile hunter-gatherers making frequent, short-term visits. Ongoing research at Jonzac and other Quina Mousterian localities will contribute to a better understanding of Neandertal behavior during cold climate phases.

    Margaret Beier, Leslie Miller, and Shu Wang's paper, Science games and the development of possible selves examines the effects of game-playing in a serious scientific game on science possible selves identity creation, utilizing a possible selves identification instrument they created. This paper continues the discussion that Beier and colleagues start in the paper by calling into question both the idea that a predictive model of science career choice can be attained by serious science game-playing and the nature of the instrument created and used by Beier and her colleagues to identify participants' creation of science possible selves. Recommendations include incorporating the idea of possible selves as being complex, dynamic and intertwined with self-concept in interpreting their findings and casting a wider net to capture the phenomena of their participants' identities and experiences by potentially making use of possible selves identification methodologies from the career training arena.

  2. The influence of action video game playing on eye movement behaviour during visual search in abstract, in-game and natural scenes.

    Azizi, Elham; Abel, Larry A; Stainer, Matthew J

    2017-02-01

    Action game playing has been associated with several improvements in visual attention tasks. However, it is not clear how such changes might influence the way we overtly select information from our visual world (i.e. eye movements). We examined whether action-video-game training changed eye movement behaviour in a series of visual search tasks including conjunctive search (relatively abstracted from natural behaviour), game-related search, and more naturalistic scene search. Forty nongamers were trained in either an action first-person shooter game or a card game (control) for 10 hours. As a further control, we recorded eye movements of 20 experienced action gamers on the same tasks. The results did not show any change in duration of fixations or saccade amplitude either from before to after the training or between all nongamers (pretraining) and experienced action gamers. However, we observed a change in search strategy, reflected by a reduction in the vertical distribution of fixations for the game-related search task in the action-game-trained group. This might suggest learning the likely distribution of targets. In other words, game training only skilled participants to search game images for targets important to the game, with no indication of transfer to the more natural scene search. Taken together, these results suggest no modification in overt allocation of attention. Either the skills that can be trained with action gaming are not powerful enough to influence information selection through eye movements, or action-game-learned skills are not used when deciding where to move the eyes.

    What is the attitude of the general public towards hunting? As a recreational activity, hunting stands apart from other forms of outdoor recreation like birdwatching in that it involves the pursuit and killing of wild animals. Today, it is in a tight spot. It has been criticized from animal ethics......, hunting organized as a group hunt, and single day leases of hunting grounds. Respondents with a “mutualist” wildlife value orientation had the most negative attitude towards hunting (39%), “distanced” respondents were the most indifferent (44%), and “utilitarians” were the most positive (61%).

  4. Stochastic noncooperative and cooperative evolutionary game strategies of a population of biological networks under natural selection.

    Chen, Bor-Sen; Yeh, Chin-Hsun

    2017-09-05

    We review current static and dynamic evolutionary game strategies of biological networks and discuss the lack of random genetic variations and stochastic environmental disturbances in these models. To include these factors, a population of evolving biological networks is modeled as a nonlinear stochastic biological system with Poisson-driven genetic variations and random environmental fluctuations (stimuli). To gain insight into the evolutionary game theory of stochastic biological networks under natural selection, the phenotypic robustness and network evolvability of noncooperative and cooperative evolutionary game strategies are discussed from a stochastic Nash game perspective. The noncooperative strategy can be transformed into an equivalent multi-objective optimization problem and is shown to display significantly improved network robustness to tolerate genetic variations and buffer environmental disturbances, maintaining phenotypic traits for longer than the cooperative strategy. However, the noncooperative case requires greater effort and more compromises between partly conflicting players. Global linearization is used to simplify the problem of solving nonlinear stochastic evolutionary games. Finally, a simple stochastic evolutionary model of a metabolic pathway is simulated to illustrate the procedure of solving for two evolutionary game strategies and to confirm and compare their respective characteristics in the evolutionary process.

    Full Text Available Researchers are increasingly exploring the role of emotions in interactive decision‐making.  Recent theories have focused on the interpersonal effects of emotions—the influence of the decisionmaker’s expressed emotions on observers’ decisions and judgments. In this paper, we examine  whether people assess others’ risk preferences on the basis of their emotional states, whether this  affects their own behavior, and how this assessment matches others’ actual behavior. To test these  ideas, we used an experimental Stag Hunt game (n = 98, and included non‐trivial financial  consequences. Participants were told (truthfully that their counterparts’ previous task had left them  happy, fearful, or emotionally neutral. People who were told their counterparts were fearful  reported that they expected less risky decisions from these counterparts than people told their  counterparts were neutral or happy. As a result, given that the Stag Hunt is a coordination game,  these participants were themselves less risky. Interestingly, these participants’ expectations were  not accurate; thus, coordination failed, and payoffs were low. This raises the possibility of a “curse  of knowledge” whereby one player’s erroneous beliefs about the effects of the counterpart’s  emotional state leads the first player to make poor action choices.

    Ermon, Stefano; Gomes, Carla P; Selman, Bart

    2012-01-01

    In this paper we introduce a class of Markov decision processes that arise as a natural model for many renewable resource allocation problems. Upon extending results from the inventory control literature, we prove that they admit a closed form solution and we show how to exploit this structure to speed up its computation. We consider the application of the proposed framework to several problems arising in very different domains, and as part of the ongoing effort in the emerging field of Computational Sustainability we discuss in detail its application to the Northern Pacific Halibut marine fishery. Our approach is applied to a model based on real world data, obtaining a policy with a guaranteed lower bound on the utility function that is structurally very different from the one currently employed.

    Full Text Available Czech Republic has a long tradition of hunting, and trophy hunting is important to manage game populations. In this study data was analysed from the five last trophy exhibitions in Czech Republic. Namely, hunter selection, compensatory selection, management selection, hunting pressure selection and depletion selection was tested in different landscape types. In compensatory hunting there is a difference between the landscape types; apparent differences exist between the landscape type with respect to hunting pressure. There was no hunter selection, or depletion selection, and no differences in management between landscape types. This study suggests that the landscape composition has an effect on selective hunting in Czech Republic.

  19. Toward brain correlates of natural behavior: fMRI during violent video games.

    Science.gov (United States)

    Mathiak, Klaus; Weber, René

    2006-12-01

    Modern video games represent highly advanced virtual reality simulations and often contain virtual violence. In a significant amount of young males, playing video games is a quotidian activity, making it an almost natural behavior. Recordings of brain activation with functional magnetic resonance imaging (fMRI) during gameplay may reflect neuronal correlates of real-life behavior. We recorded 13 experienced gamers (18-26 years; average 14 hrs/week playing) while playing a violent first-person shooter game (a violent computer game played in self-perspective) by means of distortion and dephasing reduced fMRI (3 T; single-shot triple-echo echo-planar imaging [EPI]). Content analysis of the video and sound with 100 ms time resolution achieved relevant behavioral variables. These variables explained significant signal variance across large distributed networks. Occurrence of violent scenes revealed significant neuronal correlates in an event-related design. Activation of dorsal and deactivation of rostral anterior cingulate and amygdala characterized the mid-frontal pattern related to virtual violence. Statistics and effect sizes can be considered large at these areas. Optimized imaging strategies allowed for single-subject and for single-trial analysis with good image quality at basal brain structures. We propose that virtual environments can be used to study neuronal processes involved in semi-naturalistic behavior as determined by content analysis. Importantly, the activation pattern reflects brain-environment interactions rather than stimulus responses as observed in classical experimental designs. We relate our findings to the general discussion on social effects of playing first-person shooter games.

  20. The thrill of the chase: uncovering illegal sport hunting in Brazil through YouTube™ posts

    2015-09-01

    Full Text Available The impacts of unregulated sport hunting can severely affect populations of target game species. Because hunting in Brazil is limited by law, obtaining data on illegal sport hunting in this country is challenging. We used an unusual online resource, YouTube™, to detect the occurrence of sport hunting in Brazil, measure the impacts of the activity on the main Brazilian game species and biomes, evaluate the opinions of hunters and internet users on sport hunting, and discuss the need for policy interventions in wildlife conservation in this country. We found 383 videos related to Brazilian sport hunting on YouTube™, accounting for more than 15 million views. Most videos were produced in the Cerrado (Brazilian savannah and approximately 70% of them depicted events of pursuit and killing of wild animals, especially lowland pacas (Cuniculus paca and armadillos (Family Dasypodidae. Videos were posted primarily in July and December, coinciding with the two main Brazilian vacation periods. Furthermore, the shotguns identified on videos show that sport hunters expend large sums of money to undertake their hunts. These results indicate that Brazilian sport hunters are possibly wealthier urban residents who travel to rural areas to hunt, contrasting with previous hunting studies in the country. Most viewers declared themselves in favor of sport hunting in comments (n = 2893 and ratings (n = 36,570 of the videos. Discussions generated by comments suggest that Brazilian sport hunters employ several informal management strategies to maintain game species stocks for future hunting and intensely question the restrictions of Brazilian environmental policies. Our results demonstrate that solutions are needed for the regulation of sport hunting in Brazil. Government actions, whether to increase surveillance or legalize hunting programs, should take into account the opinions of sport hunters and their perceptions on hunting dynamics to support effective policy

    Although the cheetah is recognised as the fastest land animal, little is known about other aspects of its notable athleticism, particularly when hunting in the wild. Here we describe and use a new tracking collar of our own design, containing a combination of Global Positioning System (GPS) and inertial measurement units, to capture the locomotor dynamics and outcome of 367 predominantly hunting runs of five wild cheetahs in Botswana. A remarkable top speed of 25.9 m s(-1) (58 m.p.h. or 93 km h(-1)) was recorded, but most cheetah hunts involved only moderate speeds. We recorded some of the highest measured values for lateral and forward acceleration, deceleration and body-mass-specific power for any terrestrial mammal. To our knowledge, this is the first detailed locomotor information on the hunting dynamics of a large cursorial predator in its natural habitat.

  5. The economic impact of hunting: A regional approach

    Full Text Available The core of South Africa tourism industry is based on wildlife tourism.  Private game reserves and game farms which forms part of wildlife tourism constitute most of the wildlife products in South Africa.  On these private reserves and game farms, hunting is one of the major income generators for product owners.  The aim of this study is to analyse the economic impact of hunting on the regional economies of three of South Africa’s most important hunting provinces. The study used economic multipliers, input-output analysis, and related modelling processes through input-output (supply-use tables and social accounting matrices (SAM. The results differed significantly for the three provinces, with Limpopo receiving the biggest impact (R2.6 billion and the Free State having the highest multiplier (2.08. The geographical location of the game farms, the number of farms per province and the species available all influenced the magnitude of the economic impact of hunters over and above the traditional determinants of economic impact analysis. The implication of the research is that it will help product owners in the development of game farms or hunting products, contribute to policy formulation, especially for government decisions on what products to offer where, and how to create more jobs.

    Discovery of new natural products by heterologous expression reaches its limits, especially when specific building blocks are missing in the heterologous host or the production medium. Here, we describe the insect-specific production of the new GameXPeptides E-H (5-8) from Photorhabdus luminescens TTO1, which can be produced heterologously from expression of the GameXPeptide synthetase GxpS only upon supplementation of the production media with the missing building blocks, and thus must be regarded as the true natural products under natural conditions.

    Electronic medical records (EMRs) are increasingly repurposed for activities beyond clinical care, such as to support translational research and public policy analysis. To mitigate privacy risks, healthcare organizations (HCOs) aim to remove potentially identifying patient information. A substantial quantity of EMR data is in natural language form and there are concerns that automated tools for detecting identifiers are imperfect and leak information that can be exploited by ill-intentioned data recipients. Thus, HCOs have been encouraged to invest as much effort as possible to find and detect potential identifiers, but such a strategy assumes the recipients are sufficiently incentivized and capable of exploiting leaked identifiers. In practice, such an assumption may not hold true and HCOs may overinvest in de-identification technology. The goal of this study is to design a natural language de-identification framework, rooted in game theory, which enables an HCO to optimize their investments given the expected capabilities of an adversarial recipient. We introduce a Stackelberg game to balance risk and utility in natural language de-identification. This game represents a cost-benefit model that enables an HCO with a fixed budget to minimize their investment in the de-identification process. We evaluate this model by assessing the overall payoff to the HCO and the adversary using 2100 clinical notes from Vanderbilt University Medical Center. We simulate several policy alternatives using a range of parameters, including the cost of training a de-identification model and the loss in data utility due to the removal of terms that are not identifiers. In addition, we compare policy options where, when an attacker is fined for misuse, a monetary penalty is paid to the publishing HCO as opposed to a third party (e.g., a federal regulator). Our results show that when an HCO is forced to exhaust a limited budget (set to $2000 in the study), the precision and recall of the

    2014-09-01

    Full Text Available This paper addresses the problem of resource division for robotic agents in the framework of Multi-Agent System. Knowledge of the environment represented in the system is uncertain, incomplete and distributed among the individual agents that have both limited sensing and communication abilities. The pick-up-and-collection problem is considered in order to illustrate the idea presented. In this paper a framework for cooperative task assignment to individual agents is discussed. The process of negotiating access to common resources by intercommunicating agents is modeled and solved as a game against Nature. The working of the proposed system was verified by multiple simulations. Selected, exemplary simulations are presented in the paper to illustrate the approach discussed

    Full Text Available Situla art developed as an echo of the toreutic style which had spread from the Near East through the Phoenicians, Greeks and Etruscans as far as the Veneti, Raeti, Histri, and their eastern neighbours in the region of Dolenjska (Lower Carniola. An Early Iron Age phenomenon (c. 600—300 BC, it rep- resents the major and most arresting form of the contemporary visual arts in an area stretching from the foot of the Apennines in the south to the Drava and Sava rivers in the east. Indeed, individual pieces have found their way across the Alpine passes and all the way north to the Danube. In the world and art of the situlae, a prominent role is accorded to ani- mals. They are displayed in numerous representations of human activities on artefacts crafted in the classic situla style – that is, between the late 6th  and early 5th centuries BC – as passive participants (e.g. in pageants or in harness or as an active element of the situla narrative. The most typical example of the latter is the hunting scene. Today we know at least four objects decorat- ed exclusively with hunting themes, and a number of situlae and other larger vessels where hunting scenes are embedded in composite narratives. All this suggests a popularity unparallelled by any other genre. Clearly recognisable are various hunting techniques and weapons, each associated with a particu- lar type of game (Fig. 1. The chase of a stag with javelin, horse and hound is depicted on the long- familiar and repeatedly published fibula of Zagorje (Fig. 2. It displays a hound mauling the stag’s back and a hunter on horseback pursuing a hind, her neck already pierced by the javelin. To judge by the (so far unnoticed shaft end un- der the stag’s muzzle, the hunter would have been brandishing a second jave- lin as well, like the warrior of the Vače fibula or the rider of the Nesactium situla, presumably himself a hunter. Many parallels to his motif are known from Greece, Etruria, and

    Full Text Available While hunting in traditional societies, was most commonly practised as a profession, for food, sports or entertainment, it was fully a part of Ottoman State organization as a military exercise or war game. From the first Ottoman rulers, there has been hunting institution in the palace. An organized hunting institution, regular hunting practices and the number of hunted animals had been perceived as the symbols of power of the ruler. Hunting organization was instrumental in identifying the situations of the country and people, inspecting government officials and listening to people’s problems. In this respect, the meaning of hunting ceremony gains great importance. Hunting bird-growing organization in Ottoman Empire palace had been institutionalized since early years. Its provincial administration was created for particular sanjaks. The structure of provincial hunting organization was organized in the form of taşra doğancıları (provincial falconers or hawkers, sayyad (hunters, yavrucu (fledgeling careres, yuvacı (nest carers, kayacı (carer of nest rocks, görenceci (bird observers, tuzakçı (bird catchers. There are records in Ottoman archives about this units concerning their organization, numbers, how they were spread and how the duties were passed from father to son. In this study, in the 16th century provincial Ottoman hunting organization and services in Silistra has been throughly examined, using archive documents.

  17. Hunting for Livelihood in Northeast Gabon: Patterns, Evolution, and Sustainability

    Directory of Open Access Journals (Sweden)

    Robert Nasi

    2008-12-01

    Full Text Available We suggest an ethno-biological approach to analyze the cultural and social drivers of hunting activities and assess sustainability in villages near Makokou, northeast Gabon, based on interviews with hunters, participatory mapping of hunting territories, and daily records of offtakes for 1 yr. Hunting in villages of northeast Gabon is practiced for both local consumption and cash income to cover basic family expenses. There appears to be no clear tendency to abandon subsistence hunting for commercial hunting as in other regions of Africa. Cultural and socioeconomic factors explain the temporal and spatial variation in hunting activities. Hunting increases in the dry season during circumcision ceremonies, when it is practiced mainly at > 10 km from villages, and decreases during the rainy season because most hunters are occupied by other economic activities. Degraded forest such as secondary regrowth supplies 20% of the animals killed and the greatest diversity of species at short distances from villages. Mature forest supplies the species with the greatest commercial value, e.g., red river hog (Potamochoerus porcus, and is the preferred source of meat for traditional ceremonies. In the last 15 yr, hunting patterns have changed rapidly, mainly because of the spread of gun hunting, which had serious implications for the nature of offtakes. Our results suggest that there is potential to allow hunting for resistant species such as blue duiker (Cephalophus monticola and African brush-tailed porcupine (Atherurus africanus. Other species such as red river hog and small diurnal monkeys require more attention. Specific management systems could be discussed in participatory hunting management plans to identify possible solutions to maintain the population levels of the more critical species.

  8. Wolves on the hunt: The behavior of wolves hunting wild prey

    Mech, L. David; Smith, Douglas W.; MacNulty, Daniel R.

    2015-01-01

    The interactions between apex predators and their prey are some of the most awesome and meaningful in nature—displays of strength, endurance, and a deep coevolutionary history. And there is perhaps no apex predator more impressive and important in its hunting—or more infamous, more misjudged—than the wolf. Because of wolves’ habitat, speed, and general success at evading humans, researchers have faced great obstacles in studying their natural hunting behaviors. The first book to focus explicitly on wolf hunting of wild prey, Wolves on the Hunt seeks to fill these gaps in our knowledge and understanding. Combining behavioral data, thousands of hours of original field observations, research in the literature, a wealth of illustrations, and—in the e-book edition and online—video segments from cinematographer Robert K. Landis, the authors create a compelling and complex picture of these hunters. The wolf is indeed an adept killer, able to take down prey much larger than itself. While adapted to hunt primarily hoofed animals, a wolf—or especially a pack of wolves—can kill individuals of just about any species. But even as wolves help drive the underlying rhythms of the ecosystems they inhabit, their evolutionary prowess comes at a cost: wolves spend one-third of their time hunting—the most time consuming of all wolf activities—and success at the hunt only comes through traveling long distances, persisting in the face of regular failure, detecting and taking advantage of deficiencies in the physical condition of individual prey, and through ceaseless trial and error, all while risking injury or death. By describing and analyzing the behaviors wolves use to hunt and kill various wild prey—including deer, moose, caribou, elk, Dall sheep, mountain goats, bison, musk oxen, arctic hares, beavers, and others—Wolves on the Hunt provides a revelatory portrait of one of nature’s greatest hunters.

  10. Determining the economic value of game farm tourism

    Directory of Open Access Journals (Sweden)

    P. van der Merwe

    2003-12-01

    Full Text Available Internationally tourism is accepted as one of the world's fastest-growing industries. The World Tourism Organisation (WTO indicated that tourist arrivals in 1998 grew by 2.4 % worldwide. The WTO has forecast that the number of people travelling internationally will increase from 613 million in 1997 to 1.6 billion by the year 2020. Ecotourism, which according to the WTO is any form of tourism to an unspoilt nature area,is responsible for 20 % of the world's total tourism expenditure and is also rated the fastest growing of all tourism sectors. It is also a fact that 80 % of nature conservation in South Africa is taking place on privately owned land such as game farms, and this forms part of ecotourism. The above endorses that ecotourism is an important product for South Africa and a drawcard for international as well as local tourists. The main objective of this study was to determine the economic value of game farm tourism. This will be done by determining the economic value of each of the four pillars on which game farming is based, namely hunting, ecotourism, breeding rare game species andvenison sales. Data collation was done in two ways. Firstly, research was conducted in the form of questionnaires. Game farms were randomly sampled from the database of registered game farms. The aim of this questionnaire was threefold and determined the economic contribution of game farm tourism to ecotourism. Secondly, a literature study was conducted that included the latest data by PHASA (Professional Hunters Association of South Africa, Nature Conservation and trophy hunting in South Africa. This paper will argue that game farm tourism makes a significant economic contribution to the economy of South Africa, apart from the substantial economic contribution game farm tourism already makes to conservation. This paper will be organised as follows: The first section deals with the introduction, which indicates the growth of game farm tourism; the second

  11. Managing hunting under uncertainty: from one-off ecological indicators to resilience approaches in assessing the sustainability of bushmeat hunting

    Directory of Open Access Journals (Sweden)

    Nathalie van Vliet

    2015-09-01

    Full Text Available Despite the fact that sustainability of bushmeat hunting in tropical areas is of major concern for conservation and development practitioners, we still know very little about how to measure sustainability and how to put in place sustainable bushmeat hunting systems. We review the current limits of traditional methods used to investigate sustainability of bushmeat hunting, discuss the need to incorporate the characteristics of complex systems into sustainability assessments, and suggest how resilience theories could assist in understanding bushmeat sustainability and more effective conservation of wildlife in tropical areas. Traditional methods used to assess the sustainability of bushmeat hunting include demographic models of population growth, one-off biological indicators, population trend methods, harvest-based indicators, and comparisons of demographic parameters between sites. These traditional biological sustainability indices have proved inadequate for measuring the impact of bushmeat hunting because sustainability is treated as a static, binary (yes or no question, thus ignoring stochastic processes, the inherent variability of natural systems, and the complexity of hunting systems. We suggest that bushmeat hunting systems in tropical areas should be regarded as social-ecological systems in which the impacts of hunting on prey populations are not the only focus. Instead, the analysis of resilience aims at understanding the complex and dynamic relationships between the hunting ground, its resources, the stakeholders, and the different exogenous drivers of change that affect the components of the system at different scales. The main implication of using the resilience theory in the context of bushmeat hunting is the shift from the need to assess stocks with imprecise measures to the incorporation of the uncertainty and stochasticity inherent to complex systems in participatory and adaptive management processes. As such, the resilience

    The primary purpose for the initiation of deer hunts on the Oak Ridge Reservation (ORR) was deer population control to reduce collisions with vehicles and maintain a healthy herd and habitat. As of 1997, thirteen annual deer hunts have been conducted on the ORR. The deer hunt monitoring program (DHMP) has two components -- a field screening monitoring program and a confirmatory laboratory analysis program of both retained and randomly selected released deer samples.

  18. Depletion: A Game with Natural Rules for Teaching Reaction Rate Theory

    Science.gov (United States)

    Olbris, Donald J.; Herzfeld, Judith

    2002-10-01

    Depletion is a game that reinforces central concepts of reaction rate theory through simulation. Each player buys chemicals and guides them through a series of reactions, thereby earning money to buy more chemicals. The reactions occur when players roll a high enough value on two dice to overcome an activation barrier. The reactions may be accelerated by buying heat (which allows the player to roll three dice instead of two) or catalysts (which lower the activation barrier). The value of acceleration derives from the increasing price of fresh chemicals as resources are depleted and waste products accumulate. The player who nets the most money wins the game. The details of the game are presented, with a set of follow-up questions suitable for either a quiz or discussion. Student reaction to the game is also described.

  20. Can compensatory culling offset undesirable evolutionary consequences of trophy hunting?

    Mysterud, Atle; Bischof, Richard

    2010-01-01

    1. There is growing concern about the evolutionary consequences of human harvesting on phenotypic trait quality in wild populations. Undesirable consequences are especially likely with trophy hunting because of its strong bias for specific phenotypic trait values, such as large antlers in cervids and horns in bovids. Selective hunting can cause a decline in a trophy trait over time if it is heritable, thereby reducing the long-term sustainability of the activity itself. 2. How can we build a sustainable trophy hunting tradition without the negative trait-altering effects? We used an individual-based model to explore whether selective compensatory culling of 'low quality' individuals at an early life stage can facilitate sustainability, as suggested by information from managed game populations in eastern and central Europe. Our model was rooted in empirical data on red deer, where heritability of sexual ornaments has been confirmed and phenotypic quality can be assessed by antler size in individuals as young as 1 year. 3. Simulations showed that targeted culling of low-quality yearlings could counter the selective effects of trophy hunting on the distribution of the affected trait (e.g. antler or horn size) in prime-aged individuals. Assumptions of trait heritability and young-to-adult correlation were essential for compensation, but the model proved robust to various other assumptions and changes to input parameters. The simulation approach allowed us to verify responses as evolutionary changes in trait values rather than short-term consequences of altered age structure, density and viability selection. 4. We conclude that evolutionarily enlightened management may accommodate trophy hunting. This has far reaching implications as income from trophy hunting is often channelled into local conservation efforts and rural economies. As an essential follow-up, we recommend an analysis of the effects of trophy hunting in conjunction with compensatory culling on the

  5. HUNTing the Overlap

    2005-07-08

    Hiding communication latency is an important optimization for parallel programs. Programmers or compilers achieve this by using non-blocking communication primitives and overlapping communication with computation or other communication operations. Using non-blocking communication raises two issues: performance and programmability. In terms of performance, optimizers need to find a good communication schedule and are sometimes constrained by lack of full application knowledge. In terms of programmability, efficiently managing non-blocking communication can prove cumbersome for complex applications. In this paper we present the design principles of HUNT, a runtime system designed to search and exploit some of the available overlap present at execution time in UPC programs. Using virtual memory support, our runtime implements demand-driven synchronization for data involved in communication operations. It also employs message decomposition and scheduling heuristics to transparently improve the non-blocking behavior of applications. We provide a user level implementation of HUNT on a variety of modern high performance computing systems. Results indicate that our approach is successful in finding some of the overlap available at execution time. While system and application characteristics influence performance, perhaps the determining factor is the time taken by the CPU to execute a signal handler. Demand driven synchronization at execution time eliminates the need for the explicit management of non-blocking communication. Besides increasing programmer productivity, this feature also simplifies compiler analysis for communication optimizations.

    Full Text Available Wildlife hunting is an important economic activity that contributes to the subsistence of indigenous peoples and the maintenance of their cultural identity. Changes in indigenous peoples' ways of life affect the way they manage the ecosystems and resources around them, including wildlife populations. This paper explores the relationship between cultural change, or detachment from traditional culture, and hunting behaviour among the Tsimane', an indigenous group in the Bolivian Amazon. We interviewed 344 hunters in 39 villages to estimate their hunting activity and the degree of cultural change among them. We used multilevel analyses to assess the relationships between three different proxies for cultural change at the individual level (schooling, visits to a market town, and detachment from tradition, and the following two independent variables: 1 probability of engaging in hunting (i.e., hunting activity and 2 hunting efficiency with catch per unit effort (CPUE. We found a statistically significant negative association between schooling and hunting activity. Hunting efficiency (CPUE biomass/km was positively associated with visits to a market town, when holding other co-variates in the model constant. Other than biophysical factors, such as game abundance, hunting is also conditioned by social factors (e.g., schooling that shape the hunters' cultural system and impel them to engage in hunting or deter them from doing so.

    We use the self-tuning Experience Weighted Attraction model with repeated-game strategies as a computer testbed to examine the relative frequency, speed of convergence and progression of a set of repeated-game strategies in four symmetric 2 × 2 games: Prisoner's Dilemma, Battle of the Sexes, Stag-Hunt, and Chicken. In the Prisoner's Dilemma game, we find that the strategy with the most occurrences is the "Grim-Trigger." In the Battle of the Sexes game, a cooperative pair that alternates between the two pure-strategy Nash equilibria emerges as the one with the most occurrences. In the Stag-Hunt and Chicken games, the "Win-Stay, Lose-Shift" and "Grim-Trigger" strategies are the ones with the most occurrences. Overall, the pairs that converged quickly ended up at the cooperative outcomes, whereas the ones that were extremely slow to reach convergence ended up at non-cooperative outcomes.

    Swiss Telescope at La Silla Very Successful Summary The intensive and exciting hunt for planets around other stars ( "exoplanets" ) is continuing with great success in both hemispheres. Today, an international team of astronomers from the Geneva Observatory and other research institutes [1] is announcing the discovery of no less than eleven new, planetary companions to solar-type stars, HD 8574, HD 28185, HD 50554, HD 74156, HD 80606, HD 82943, HD 106252, HD 141937, HD 178911B, HD 141937, among which two new multi-planet systems . The masses of these new objects range from slightly less than to about 10 times the mass of the planet Jupiter [2]. The new detections are based on measured velocity changes of the stars [3], performed with the CORALIE spectrometer on the Swiss 1.2-m Leonard Euler telescope at the ESO La Silla Observatory , as well as with instruments on telescopes at the Haute-Provence Observatory and on the Keck telescopes on Mauna Kea (Hawaii, USA). Some of the new planets are unusual: * a two-planet system (around the star HD 82943) in which one orbital period is nearly exactly twice as long as the other - cases like this (refered to as "orbital resonance") are well known in our own solar system; * another two-planet system (HD 74156), with a Jupiter-like planet and a more massive planet further out; * a planet with the most elongated orbit detected so far (HD 80606), moving between 5 and 127 million kilometers from the central star; * a giant planet moving in an orbit around its Sun-like central star that is very similar to the one of the Earth and whose potential satellites (in theory, at least) might be "habitable". At this moment, there are 63 know exoplanet candidates with minimum masses below 10 Jupiter masses, and 67 known objects with minimum masses below 17 Jupiter masses. The present team of astronomers has detected about half of these. PR Photo 13a/01 : Radial-velocity measurements of HD 82943, a two-planet system . PR Photo 13b/01 : Radial

    Full Text Available Abstract Background Subsistence hunting is a traditional practice providing food and many other goods for households in the Yucatan Peninsula, southeast Mexico. Economic, demographic, and cultural change in this region drive wildlife habitat loss and local extinctions. Improving our understanding about current practices of wildlife use may support better management strategies for conserving game species and their habitat. We aimed to evaluate if wildlife use remained relevant for the subsistence of rural residents of the Yucatan Peninsula, as well as if local hunting practices were related to environmental, geographical, and cultural factors. Methods Fieldwork was done between March 2010 and March 2011. Information was obtained through conversations, interviews, and participant observation. Record forms allowed recording animals hunted, biomass extracted, distance intervals to hunting sites, habitat types and seasonality of wildlife harvests. Data were analyzed using one-way Analysis of Variance, and Generalized Linear Models. Results Forty-six terrestrial vertebrate species were used for obtaining food, medicine, tools, adornments, pets, ritual objects, and for sale and mitigating damage. We recorded 968 animals taken in 664 successful hunting events. The Great Curassow, Ocellated Turkey, paca, white-tailed deer, and collared peccary were the top harvested species, providing 80.7% of biomass (10,190 kg. The numbers of animals hunted and biomass extracted declined as hunting distances increased from villages. Average per capita consumption was 4.65 ± 2.7 kg/person/year. Hunting frequencies were similar in forested and agricultural areas. Discussion Wildlife use, hunting patterns, and technologies observed in our study sites were similar to those recorded in previous studies for rural Mayan and mestizo communities in the Yucatan Peninsula and other Neotropical sites. The most heavily hunted species were those providing more products and by

    Full Text Available The focus of this paper is on the traditional Saami hunting in relation to the animal and hunting motifs on their drum, more specifially the southern Saami drums. One may wonder if it is possible for anyone to interpret a picture unconditionally. One has a certain ground of one's own to stand on and the question arises of whether this is the correct position, when -as in the present case — we approach another culture. We naturally include the experiences of our own culture in interpretations of another culture. The animal which is the commonest species on the southern Saami drums, is the reindeer. Other animals that occur are elks, wolves, beavers, foxes, snakes, among others. Considering the Saamis' hunting weapons, the most important of these were the bow and arrow, and the spear or spear shaft. Of these weapons it is the bow which is most often portrayed on drums. Also some trapping implement like a gin may appear on a drum, but in general we have little or no information about hunting or trapping methods at all.

    Although deforestation and forest degradation have long been considered the most significant threats to tropical biodiversity, across Southeast Asia (Northeast India, Indochina, Sundaland, Philippines) substantial areas of natural habitat have few wild animals (>1 kg), bar a few hunting-tolerant species. To document hunting impacts on vertebrate populations regionally, we conducted an extensive literature review, including papers in local journals and reports of governmental and nongovernmental agencies. Evidence from multiple sites indicated animal populations declined precipitously across the region since approximately 1980, and many species are now extirpated from substantial portions of their former ranges. Hunting is by far the greatest immediate threat to the survival of most of the region's endangered vertebrates. Causes of recent overhunting include improved access to forests and markets, improved hunting technology, and escalating demand for wild meat, wildlife-derived medicinal products, and wild animals as pets. Although hunters often take common species, such as pigs or rats, for their own consumption, they take rarer species opportunistically and sell surplus meat and commercially valuable products. There is also widespread targeted hunting of high-value species. Consequently, as currently practiced, hunting cannot be considered sustainable anywhere in the region, and in most places enforcement of protected-area and protected-species legislation is weak. The international community's focus on cross-border trade fails to address overexploitation of wildlife because hunting and the sale of wild meat is largely a local issue and most of the harvest is consumed in villages, rural towns, and nearby cities. In addition to improved enforcement, efforts to engage hunters and manage wildlife populations through sustainable hunting practices are urgently needed. Unless there is a step change in efforts to reduce wildlife exploitation to sustainable levels, the

    Tanzania holds most of the remaining large populations of African lions (Panthera leo) and has extensive areas of leopard habitat (Panthera pardus), and both species are subjected to sizable harvests by sport hunters. As a first step toward establishing sustainable management strategies, we analyzed harvest trends for lions and leopards across Tanzania's 300,000 km(2) of hunting blocks. We summarize lion population trends in protected areas where lion abundance has been directly measured and data on the frequency of lion attacks on humans in high-conflict agricultural areas. We place these findings in context of the rapidly growing human population in rural Tanzania and the concomitant effects of habitat loss, human-wildlife conflict, and cultural practices. Lion harvests declined by 50% across Tanzania between 1996 and 2008, and hunting areas with the highest initial harvests suffered the steepest declines. Although each part of the country is subject to some form of anthropogenic impact from local people, the intensity of trophy hunting was the only significant factor in a statistical analysis of lion harvest trends. Although leopard harvests were more stable, regions outside the Selous Game Reserve with the highest initial leopard harvests again showed the steepest declines. Our quantitative analyses suggest that annual hunting quotas be limited to 0.5 lions and 1.0 leopard/1000 km(2) of hunting area, except hunting blocks in the Selous Game Reserve, where harvests should be limited to 1.0 lion and 3.0 leopards/1000 km(2) .

  17. Criteria and indicators of sustainable hunting – the Austrian assessment approach

    Directory of Open Access Journals (Sweden)

    Lexer, W.

    2005-12-01

    Full Text Available Concepts and assessment tools for sustainable natural resource management have been developed in, amongst others, forestry, agriculture, fishery and tourism, but not for hunting or wildlife management. We applied a broad participatory stakeholder approach for the development of criteria and indicators of sustainable hunting in Austria. Based on international and national obligations and provisions, the concept is operational by defining ecological, economic and socio-cultural principles, criteria and sub-criteria with indicators and performance scales. The assessment set enables hunters to assess the degree of sustainability of their own individual practice of hunting in a self-reliant way. Its main function is to serve as a decision-supporting and awareness-raising instrument on hunting to identify deficiencies in sustainability, provide guidance for more sustainable future hunting practices and monitor effectiveness of management actions. The concept allows adaptation to specific regional conditions and different national hunting systems and application on regional and supra-regional scales.

    its prevalence suggests that it is both adaptive and that it has an underlying pharmacological explanation. We hypothesize that hallucinogenic plants alter perception in hunting dogs by diminishing extraneous signals and by enhancing sensory perception (most likely olfaction) that is directly involved in the detection and capture of game. If this is true, plant substances also might enhance the ability of dogs to detect explosives, drugs, human remains, or other targets for which they are valued. Copyright © 2015 Elsevier Ireland Ltd.

    Koster, Jeremy M; Tankersley, Kenneth B

    2012-02-21

    In past and modern human societies, dogs have played an important role as hunting companions. Given considerable ethnographic evidence that dogs vary in their hunting abilities, this paper addresses the effects of key demographic variables, namely age and sex, on the amount of harvested game that dogs contribute in an indigenous Nicaraguan community. Controlling for variation in the time spent potentially hunting, male dogs and older dogs are significantly associated with greater harvests. These results may account for documented preferences for males in both archaeological and ethnographic contexts. Among societies in which dogs are used both as hunting companions and sources of food, the age-related delay in peak hunting ability also suggests a tradeoff that might explain the consumption of dogs shortly after they have reached adult size. Informant rankings of two cohorts of dogs indicate that residents of the community exhibit high agreement about the relative abilities of the dogs, and the rankings indicate that dogs from the same household exhibit comparable skill. There is little evidence that talented, highly-ranked dogs are provided a more nutritious diet, as measured by nitrogen-based and carbon-based isotopic analysis of hair samples. Overall, although dogs can be quite advantageous as hunting companions, this research suggests that the heterogeneity of hunting ability combines with the high mortality of dogs to impose risks on households that depend on dogs as a source of harvested meat.

The powerful influence of Italian and French opera schools, as well as the Italian Commedia Dell'arte led to the flourishing of music and theatre art in Austria: opera buffa (A. Salieri, Ch. W. Glück, J. Haydn, W. A. Mozart, fairy-tale comedies of F. Raimund and satirical dramas of Nestroy. Their game-like nature finds its expression in musical turns, satirical songs and duets. Viennese dance operetta has absorbed the traditions of Viennese popular comedy and comic opera. Recitative, vocal music and folk dances were the key elements of operettas (J.

  7. Galaxy 'Hunting' Made Easy

    Galaxies found under the Glare of Cosmic Flashlights Astronomers using ESO's Very Large Telescope have discovered in a single pass about a dozen otherwise invisible galaxies halfway across the Universe. The discovery, based on a technique that exploits a first-class instrument, represents a major breakthrough in the field of galaxy 'hunting'. ESO PR Photo 40a/07 ESO PR Photo 40a/07 Newly Found Galaxies (SINFONI/VLT) The team of astronomers led by Nicolas Bouché have used quasars to find these galaxies. Quasars are very distant objects of extreme brilliance, which are used as cosmic beacons that reveal galaxies lying between the quasar and us. The galaxy's presence is revealed by a 'dip' in the spectrum of the quasar - caused by the absorption of light at a specific wavelength. The team used huge catalogues of quasars, the so-called SDSS and 2QZ catalogues, to select quasars with dips. The next step was then to observe the patches of the sky around these quasars in search for the foreground galaxies from the time the Universe was about 6 billion years old, almost half of its current age. "The difficulty in actually spotting and seeing these galaxies stems from the fact that the glare of the quasar is too strong compared to the dim light of the galaxy," says Bouché. This is where observations taken with SINFONI on ESO's VLT made the difference. SINFONI is an infrared 'integral field spectrometer' that simultaneously delivers very sharp images and highly resolved colour information (spectra) of an object on the sky. ESO PR Photo 32e/07 ESO PR Photo 40b/07 Chasing 'Hidden' Galaxies (Artist's Impression) With this special technique, which untangles the light of the galaxy from the quasar light, the team detected 14 galaxies out of the 20 pre-selected quasar patches of sky, a hefty 70% success rate. "This high detection rate alone is a very exciting result," says Bouché. "But, these are not just ordinary galaxies: they are most notable ones, actively forming a lot of

    Conservation scientists are increasingly focusing on the drivers of human behavior and on the implications of various sources of uncertainty for management decision making. Trophy hunting has been suggested as a conservation tool because it gives economic value to wildlife, but recent examples show that overharvesting is a substantial problem and that data limitations are rife. We use a case study of trophy hunting of an endangered antelope, the mountain nyala (Tragelaphus buxtoni), to explore how uncertainties generated by population monitoring and poaching interact with decision making by 2 key stakeholders: the safari companies and the government. We built a management strategy evaluation model that encompasses the population dynamics of mountain nyala, a monitoring model, and a company decision making model. We investigated scenarios of investment into antipoaching and monitoring by governments and safari companies. Harvest strategy was robust to the uncertainty in the population estimates obtained from monitoring, but poaching had a much stronger effect on quota and sustainability. Hence, reducing poaching is in the interests of companies wishing to increase the profitability of their enterprises, for example by engaging community members as game scouts. There is a threshold level of uncertainty in the population estimates beyond which the year-to-year variation in the trophy quota prevented planning by the safari companies. This suggests a role for government in ensuring that a baseline level of population monitoring is carried out such that this level is not exceeded. Our results illustrate the importance of considering the incentives of multiple stakeholders when designing frameworks for resource use and when designing management frameworks to address the particular sources of uncertainty that affect system sustainability most heavily.

    It is argued that trophy hunting of large, charismatic mammal species can have considerable conservation benefits but only if undertaken sustainably. Social-ecological theory suggests such sustainability only results from developing governance systems that balance financial and biological requirements. Here we use lion (Panthera leo) trophy hunting data from Tanzania to investigate how resource ownership patterns influence hunting revenue and offtake levels. Tanzania contains up to half of the global population of free-ranging lions and is also the main location for lion trophy hunting in Africa. However, there are concerns that current hunting levels are unsustainable. The lion hunting industry in Tanzania is run by the private sector, although the government leases each hunting block to companies, enforces hunting regulation, and allocates them a species-specific annual quota per block. The length of these leases varies and theories surrounding property rights and tenure suggest hunting levels would be less sustainable in blocks experiencing a high turnover of short-term leases. We explored this issue using lion data collected from 1996 to 2008 in the Selous Game Reserve (SGR), the most important trophy hunting destination in Tanzania. We found that blocks in SGR with the highest lion hunting offtake were also those that experienced the steepest declines in trophy offtake. In addition, we found this high hunting offtake and the resultant offtake decline tended to be in blocks under short-term tenure. In contrast, lion hunting levels in blocks under long-term tenure matched more closely the recommended sustainable offtake of 0.92 lions per 1000 km2. However, annual financial returns were higher from blocks under short-term tenure, providing $133 per km2 of government revenue as compared to $62 per km2 from long-term tenure blocks. Our results provide evidence for the importance of property rights in conservation, and support calls for an overhaul of the system in

    2010-01-01

    We construct quantum games from a table of non-factorizable joint probabilities, coupled with a symmetry constraint, requiring symmetrical payoffs between the players. We give the general result for a Nash equilibrium and payoff relations for a game based on non-factorizable joint probabilities, which embeds the classical game. We study a quantum version of Prisoners' Dilemma, Stag Hunt, and the Chicken game constructed from a given table of non-factorizable joint probabilities to find new outcomes in these games. We show that this approach provides a general framework for both classical and quantum games without recourse to the formalism of quantum mechanics.

    2010-03-23

    Evolutionary game dynamics of two players with two strategies has been studied in great detail. These games have been used to model many biologically relevant scenarios, ranging from social dilemmas in mammals to microbial diversity. Some of these games may, in fact, take place between a number of individuals and not just between two. Here we address one-shot games with multiple players. As long as we have only two strategies, many results from two-player games can be generalized to multiple players. For games with multiple players and more than two strategies, we show that statements derived for pairwise interactions no longer hold. For two-player games with any number of strategies there can be at most one isolated internal equilibrium. For any number of players with any number of strategies , there can be at most isolated internal equilibria. Multiplayer games show a great dynamical complexity that cannot be captured based on pairwise interactions. Our results hold for any game and can easily be applied to specific cases, such as public goods games or multiplayer stag hunts.

  10. [Role of modern hunting in wildlife management].

    Science.gov (United States)

    Cao, Shi; Zhou, Xue-Hong; Zhang, Wei

    2014-01-01

    Although modern hunting is different from traditional hunting, it remains a controversial topic. A large number of scholars in the world have studied the effects of hunting on wild animals from an ecological, ethological, genetic and economic aspect. This paper reviewed the role of controlled hunting in wildlife production from population dynamics, behavior, genetic and a phenotypic level, and by integrating a large number of domestic and foreign literatures. Many studies have shown that regulated hunting is an efficient approach in managing wildlife populations, which could be beneficial to the recovery and possibly even growth of wildlife populations. Meanwhile, over-exploitation or inappropriate hunting could affect the sex, birth and mortality ratios of wildlife populations, change foraging behavior and socio-spatial behavior and generate artificial selection of their genotype and phenotype. To apply modern hunting properly to wildlife management, China could learn from successful hunting programs implemented in many other countries, which are based on ecological and economic principles to formulate scientifically determined hunting quotas and set up an effective system to regulate and manage the hunting of wildlife populations.

    Primates are regularly hunted for bushmeat in tropical forests, and systematic ecological monitoring can help determine the effect hunting has on these and other hunted species. Monitoring can also be used to inform law enforcement and managers of where hunting is concentrated. We evaluated the effects of law enforcement informed by monitoring data on density and spatial distribution of 8 monkey species in Taï National Park, Côte d'Ivoire. We conducted intensive surveys of monkeys and looked for signs of human activity throughout the park. We also gathered information on the activities of law-enforcement personnel related to hunting and evaluated the relative effects of hunting, forest cover and proximity to rivers, and conservation effort on primate distribution and density. The effects of hunting on monkeys varied among species. Red colobus monkeys (Procolobus badius) were most affected and Campbell's monkeys (Cercopithecus campbelli) were least affected by hunting. Density of monkeys irrespective of species was up to 100 times higher near a research station and tourism site in the southwestern section of the park, where there is little hunting, than in the southeastern part of the park. The results of our monitoring guided law-enforcement patrols toward zones with the most hunting activity. Such systematic coordination of ecological monitoring and law enforcement may be applicable at other sites. ©2012 Society for Conservation Biology.

  13. From Subsistence to Commercial Hunting: Technical Shift in Cynegetic Practices Among Southern Cameroon Forest Dwellers During the 20th Century

    Directory of Open Access Journals (Sweden)

    Edmond Dounias

    2016-03-01

    Full Text Available Tropical rainforest dwellers, who are currently engaged in bushmeat trade, used to track game for their own subsistence. We investigate the technical evolution over the past century of bushmeat procurement by the Fang, a group of southern Cameroon forest dwellers who are renowned for their extensive cynegetic expertise. This investigation consists of a diachronic approach to assess Fang hunting and trapping technology by comparing firsthand data on bushmeat procurement collected in the early 1990s with detailed descriptions recorded in the early 1900s among the same populations by the German anthropologist Günter Tessmann. Other archive sources bequeathed by explorers in the twilight of the 19th century are also exploited. The comparison conveys a more dynamic view of hunting practices following the greater involvement of the Fang hunters in the bushmeat trade. Historical sources remind us that projectile weapons were initially destined for warfare and that trapping, mobilizing a vast panel of modalities, was the prominent means to catch game for domestic consumption. Net hunting and crossbow hunting, which used to be typical Fang activities, are now exclusively conducted by Pygmies; spear hunting with hounds has become anecdotal. If a large range of trap mechanisms is still functional, effort is now focused on snares, elicited by the banalization of twisted wire cable. The legacy of other remaining models is left to children who carry out a didactic form of garden trapping. The major detrimental change is the use of firearms, which were initially adopted as a warfare prestige attribute before becoming the backbone instrument of bushmeat depletion. Revisiting the past provides useful lessons for improving current hunting management, through the promotion of garden hunting and wildlife farming, and the revitalization of a collective and cultural art of hunting as an alternative to indiscriminate overhunting by neophyte and increasingly

    Pigeon, Gabriel; Festa-Bianchet, Marco; Coltman, David W; Pelletier, Fanie

    2016-04-01

    The potential for selective harvests to induce rapid evolutionary change is an important question for conservation and evolutionary biology, with numerous biological, social and economic implications. We analyze 39 years of phenotypic data on horn size in bighorn sheep (Ovis canadensis) subject to intense trophy hunting for 23 years, after which harvests nearly ceased. Our analyses revealed a significant decline in genetic value for horn length of rams, consistent with an evolutionary response to artificial selection on this trait. The probability that the observed change in male horn length was due solely to drift is 9.9%. Female horn length and male horn base, traits genetically correlated to the trait under selection, showed weak declining trends. There was no temporal trend in genetic value for female horn base circumference, a trait not directly targeted by selective hunting and not genetically correlated with male horn length. The decline in genetic value for male horn length stopped, but was not reversed, when hunting pressure was drastically reduced. Our analysis provides support for the contention that selective hunting led to a reduction in horn length through evolutionary change. It also confirms that after artificial selection stops, recovery through natural selection is slow.

    Toxigenic Corynebacterium ulcerans is a zoonotic pathogen that produces diphtheria toxin and causes a diphtheria-like illness in humans. The organism is known to infect and circulate among dogs, which can then transmit it to humans. Furthermore, previous studies have found that C. ulcerans is carried by wild animals, including game animals. In the present study, we tested hunting and companion dogs for the presence of toxigenic C. ulcerans and succeeded in isolating the bacterium from a hunting dog. Moreover, several hunting dogs had serum diphtheria antitoxin titers that were higher than the titers required for protection in humans, suggesting a history of exposure to toxigenic Corynebacterium strains. Notably, ribotyping, pulsed-field gel electrophoresis and tox gene sequencing demonstrated that the isolate from the hunting dog clustered with previously characterized C. ulcerans strains isolated from wild animals, as opposed to groups of isolates from humans and companion dogs. Interestingly, the wild animal cluster also contains an isolate from an outdoor breeding dog, which could have formed a bridge between isolates from wild animals and those from companion dogs. The results presented herein provide insight into the mechanism by which the zoonotic pathogen C. ulcerans circulates among wild animals, hunting and companion dogs, and humans.

    Full Text Available In the world scale, there are various forms of how the hunting tourism is carried out. there is a considerably specific situation in the czech republic originating in the historical development. the assessment of the diversification of the demand for tourist activities was chosen to be the aim of this article. this assessment is based on a questionnaire survey among tourism participants who consume the specific products of the hunting tourism in the tourist regions of Bohemian Forest and south Bohemia. A guided tour in a game enclosure with a professional commentary and wildlife observation showed to be the most interesting offer. the most important thing is the identification of five main segments of demand called “ordinary” gamekeeper's hunting, “occasional” gamekeeper's hunting, angling activities, hunting without the killing and complementary activities. the differences among the latter five segments were identified in the representation of respondents as far as their gender and their membership in a community of anglers or gamekeepers are concerned.

  3. Multiple-host pathogens in domestic hunting dogs in Nicaragua's Bosawás Biosphere Reserve.

    Fiorello, Christine V; Straub, Mary H; Schwartz, Laura M; Liu, James; Campbell, Amanda; Kownacki, Alexa K; Foley, Janet E

    2017-03-01

    Nicaragua's Bosawás Biosphere Reserve is a vast forested area inhabited largely by indigenous Mayangna and Miskitu people. Most Bosawás residents rely on subsistence hunting and swidden agriculture, and hunting dogs are important for finding and securing wild game. We investigated the health of hunting dogs in three communities differing in location, size, and economy. Dogs in all communities were nutritionally compromised and experienced a heavy burden of disease. Seroprevalence of canine distemper, canine parvovirus, Rickettsia rickettsii, and Leptospira spp. exceeded 50% of dogs. At least one dog was actively shedding leptospires in urine, and many dogs were anemic and/or dehydrated. These dogs interact with wildlife in the forest and humans and domestic livestock in the communities, and may therefore serve as sources of zoonotic and wildlife diseases. Bosawás represents one of the largest intact tracts of habitat for jaguars (Panthera onca) in Central America, and given that these communities are located within the forest, jaguars may be at risk from disease spillover from hunting dogs. Dog owners reported that four of 49 dogs had been attacked and killed by jaguars in the past year, and that retaliatory killing of jaguars was sometimes practiced. Disease spillover from dogs to wildlife could occur both in the course of dogs' hunting activities as well as during jaguar attacks. A better understanding of dog depredation by jaguars, pathogen exposure in jaguars, and a management strategy for the hunting dog population, are urgently needed to mitigate these dual threats to jaguars, improve the lives of hunting dogs, and safeguard the health of their owners.

    Conservation organizations have increasingly raised concerns about escalating rates of illegal hunting and trade in wildlife. Previous studies have concluded that people hunt illegally because they are financially poor or lack alternative livelihood strategies. However, there has been little attempt to develop a richer understanding of the motivations behind contemporary illegal wildlife hunting. As a first step, we reviewed the academic and policy literatures on poaching and illegal wildlife use and considered the meanings of poverty and the relative importance of structure and individual agency. We placed motivations for illegal wildlife hunting within the context of the complex history of how wildlife laws were initially designed and enforced to indicate how hunting practices by specific communities were criminalized. We also considered the nature of poverty and the reasons for economic deprivation in particular communities to indicate how particular understandings of poverty as material deprivation ultimately shape approaches to illegal wildlife hunting. We found there is a need for a much better understanding of what poverty is and what motivates people to hunt illegally.

    Full Text Available Actual worship or veneration of wolf is not known in Estonian folk tradition. Wolf is a wild animal and oral lore about it, which has sprung from herding lore, is versatile and affluent. In the Estonian tradition, wolf was a force of nature that had to be considered – and respected. Already the large number of euphemisms about the wolf is evidence of the great respect for this animal. The veneration of wolf as a predator is described in several Estonian lore texts as follows:(a people recognised its right to catch. For this purpose each farm allotted a portion of its produce for the wolf;(b because the wolf’s right to catch, disturbing, or even scolding a wolf departing with a catch was prohibited;(c a wolf’s catch could not be used;(d people believed that by slaughtering domestic animals, a wolf also encourages their breeding;(e when a wolf was encountered, it had to be addressed in kind words;(f people were afraid of ravaging a wolf’s den for fear of revenge.A wolf – parts and substances of his body and the animal itself – was expected to provide help and protection. The narratives mention wolf’s flesh, throat, skull, fangs, tail, hair and faeces. These were believed to help people to cure their ailments, ensure success and luck in household chores, work, offer protection against evil forces and bring luck in personal life.In Estonian folk medicine, wolf meat has been used to cure rheumatism; a person who ate its meat was believed to get the magical power to heal other people. Throat was used for beekeeping and growing crops. The skull was kept in the granary as a protective charm. Fangs were used for two purposes: to speed up babies’ teething and as amulets or charms. Tail was used in both love and work magic. Wolf ’s hair was used for treating typhoid fever (hundiviga, soetõbi, literally ‘wolf ’s disease’. Excrements were used for treating colic.People expected wolf itself to offer help. When they were seen

    A 36-year-old man presented with facial nerve palsy, hearing loss, vertigo and headache. He was initially diagnosed with Ramsay Hunt syndrome and treated with a systemic steroid and valaciclovir; however, his symptoms deteriorated. Serum rapid plasma reagin (RPR) and treponema pallidum hemagglutination tests were positive. Cerebrospinal fluid analysis revealed an elevated white blood cell count and positive RPR, confirming the diagnosis of neurosyphilis. Penicillin G (PCG) was administered, and his facial nerve function and headache improved. However, left-side hearing loss worsened temporarily, which was assumed to be a Jarisch-Herxheimer reaction. Betamethasone was administered along with PCG, and he recovered completely.

    2010-08-01

    The Hponkanrazi Wildlife Sanctuary, North Myanmar and three contiguous protected areas, comprise some of the largest expanses of natural forest remaining in the region. Demand for wildlife products has resulted in unsustainable exploitation of commercially valuable species resulting in local extirpation of vulnerable species. Camera trap, track and sign, and questionnaire-based surveys were used to examine (a) wildlife species targeted by hunters, (b) the importance of wild meat for household consumption, and (c) the significance of hunting as a livelihood activity for resident villages. Certain commercially valuable species highly preferred by hunters were either completely absent from hunt records (tiger, musk deer and otter) or infrequently obtained during actual hunts (bear, pangolin). Species obtained by hunters were commonly occurring species such as muntjacs with low commercial value and not highly preferred by hunters. Fifty eight percent of respondents ( n = 84) indicated trade, 27% listed subsistence use and 14% listed human-wildlife conflict as the main reason for hunting ( n = 84). Average amount of wild meat consumed per month is not significantly higher during the hunting season compared to the planting season (paired t-test, P > 0.05). Throughout the year, the average amount of fish consumed per month was higher than livestock or wild meat (Friedman test, P < 0.0001). Hunting is driven largely by trade and wild meat, while not a critical source of food for a large number of families could potentially be an important, indirect source of access to food for hunting families. Findings and trends from this study are potentially useful in helping design effective conservation strategies to address globally prevalent problems of declining wildlife populations and dependent human communities. The study provides recommendations to reduce illegal hunting and protect vulnerable species by strengthening park management through enforcement, increasing the

  20. The Hundred Year Hunt for the Red Sprite

    Lyons, W. A.; Schmidt, M.

    2003-12-01

    This presentation reviews an NSF Informal Science Education project directed by the PO of an ongoing NSF Physical Meteorology/Aeronomy-sponsored research program on red sprites. For over 100 years, anecdotal reports and citations in the literature have persisted of strange luminous apparitions occurring high above thunderstorms. They were long discounted by the scientific community - until 1989, when by pure chance, a video revealed two giant pillars of light extending tens of kilometers above a thunderstorm. Since then, thousands of events, now called sprites, have been imaged, many by the PI. Mesospheric sprites, at 40 to 90 km altitude, are induced by lightning discharges having highly unusual characteristics. Science is now gradually unraveling the nature of the giant lightning discharges which spawn sprites. In the process we have found even more unusual electrical discharges above thunderstorms, suggesting that many new discoveries await to be made. We produced and are distributing a planetarium DVD/video program (42 minutes length) entitled, "The Hundred Year Hunt for the Red Sprite." It documents the application of the scientific method to unraveling this century old mystery surrounding strange lights in the night sky. We also contrasted this story of discovery to the pseudo-science prevalent today in topics such as UFOs. With distribution to numerous planetaria and science centers, we believe over 200,000 persons will eventually view this program (which has won three major video production awards). Our long term goal is to inspire planetarium visitors to undertake their own self-directed learning programs. A companion educational web site (www.Sky-Fire.TV) allows students and adults sufficiently motivated by the planetarium experience to further investigate sprites and related basic science topics. The highly interactive web site challenges visitors to test their knowledge of sprites and lightning by participating in an on-line 20 question quiz game, which

    Full Text Available Galați county is a geographical area that is less valued in terms of tourism, but which benefits by a natural tourism potential. The aim of this study is to identify the potential and the activities of the hunting and fishing tourism. Exploitation of hunting and fishing activities in touristic aim is only partial because of the lack of touristic infrastructure and the lack of collaboration with various travel agencies from this branch of tourism. Proposals that would help the future development and improvement of tourism activity are from “wildlife watching tourism” domain: capturing images with the camera, observing the behavior of hunting species without affecting them, providing information for those interested in the hunting behavior and life fauna, creating a wildlife museum and last but not least, upgrading the transport infrastructure.

  6. How game changers catalyzed, disrupted, and incentivized social innovation: three historical cases of nature conservation, assimilation, and women's rights

    Directory of Open Access Journals (Sweden)

    Frances R. Westley

    2016-12-01

    Full Text Available We explore the impact of "game changers" on the dynamics of innovation over time in three problem domains, that of wilderness protection, women's rights, and assimilation of indigenous children in Canada. Taking a specifically historical and cross-scale approach, we look at one social innovation in each problem domain. We explore the origins and history of the development of the National Parks in the USA, the legalization of contraception in the USA and Canada, and the residential school system in Canada. Based on a comparison of these cases, we identify three kinds of game changers, those that catalyze social innovation, which we define as "seminal," those that disrupt the continuity of social innovation, which we label exogenous shocks, and those that provide opportunities for novel combinations and recombinations, which we label as endogamous game changers.

  7. Opportunistic Migration in Spatial Evolutionary Games

    CERN Document Server

    Buesser, Pierre; Antonioni, Alberto

    2013-01-01

    We study evolutionary games in a spatial diluted grid environment in which agents strategically interact locally but can also opportunistically move to other positions within a given migration radius. Using the imitation of the best rule for strategy revision, it is shown that cooperation may evolve and be stable in the Prisoner's Dilemma game space for several migration distances but only for small game interaction radius while the Stag Hunt class of games become fully cooperative. We also show that only a few trials are needed for cooperation to evolve, i.e. searching costs are not an issue. When the stochastic Fermi strategy update protocol is used cooperation cannot evolve in the Prisoner's Dilemma if the selection intensity is high in spite of opportunistic migration. However, when imitation becomes more random, fully or partially cooperative states are reached in all games for all migration distances tested and for short to intermediate interaction radii.

    Full Text Available The detailed analysis was completed on long­term population dynamics data of different game mammals conducted in the region of the Middle Amur. The study showed that when a certain stability of the majority of the total number of game animals throughout the Jewish Autonomous Region (the coefficient of Malthus model for the entire period of observation a little more than 1, except for the lynx, kolinsky and squirrel from the mid 90s of the last century indicates a steady downward trend in population numbers, especially in areas where hunting occurs (Malthus model coefficients less than 1. Perhaps the reason for the decline was the increase in the amount of poaching in the 90s due to the deteriorating socio­economic situation in the country. Impression of a certain stability in the JAR as a whole due to the position of animals in protected areas. For all considered commercial species in the reserve there is a clear tendency for the number. For such species as the kolinsky, squirrel and bears, the maximum possible model number lower than the maximum number of accounting was observed during the study period. For populations of other game animals it can be assumed that the status of their ecological niches, i.e. habitat resources (supply of food, the size of the range, availability and propagation of the growth of the offspring, etc. are relatively stable. The relation between the amount of natural reproduction of «local» populations and their replenishment quantities due to external migration was studied in detail. Maintaining the number of target species is determined by migratory activity. The presence of protected areas helps to maintain and even some increase the population numbers, but it is clearly insufficient. It’s necessary to expand the territories free from the hunt and the transition to the strategies of hard periodic limitations of hunting populations experiencing depressive mode of population dynamics.

    Full Text Available Aim. The goal of the research is that: to identify the taxonomic composition of game species and make full list of species to assess the current state of populations and resources to carry out eco-faunistic analysis of the distribution of game mammals habiting Shelkovskiy district of Chechnya. Methods. We used mapping techniques, various methods of census forms and scientific processing of the collected material, systematic and bioecological analysis. Results. As a result, we have identified 5 ecological complexes and characterized them by distribution on the identified and described natural habitats. We have made an inventory of species, identified conditions of rare species and determined their status. Biometric data has been obtained for a number of species; their biological and ecological features have been described. We also identified the species composition of game mammals and their spatial distribution of habitats. The differentiation of species in ecological groups has been carried out. Data has been obtained on the number of nine major types for the period of 2012-2013, and their characteristics. We have made an estimation of ecological and economic potential of resources of game mammals of the study area. Conclusions. Based on the analysis of the results we can make a judgment about the level of biodiversity of species of game mammals of the studied area, the current state of their number and possible use for commercial, sports and recreational purposes. We propose specific measures such as the use of existing biological resources i.e. species of mammals, as well as the creation of new protected areas as a form of preserving and increasing the number of mammals in the area. The research results can be useful for monitoring and creating specially protected natural reservations, protection of endangered species. The findings have implications for the organization of hunting economy to increase the number of game animals.

    Benjamin, S C; Benjamin, Simon C.; Hayden, Patrick M.

    2001-01-01

    Game theory is a mature field of applied mathematics. It formalizes the conflict between competing agents, and has found applications ranging from economics through to biology. Recently the first efforts have been made to introduce quantum information into game theory. For two-player games, it has been found that when the allowed `moves' are extended to include everything quantum mechanically possible, then the predominant strategies in the game can disappear, and only reappear if the players degrade the quantum coherence. Here we present the first study of quantum games with more than two players. We demonstrate that such games can exhibit `coherent' equilibrium strategies which have no analogue in classical games, or even in two-player quantum games. These equilibria are generally of a cooperative nature: quantum players can exploit their environment highly efficiently through the use of collaborative strategies.

    Ito, Hiromu; Katsumata, Yuki; Hasegawa, Eisuke; Yoshimura, Jin

    2017-01-01

    The evolution of cooperative behavior is one of the most important issues in game theory. Previous studies have shown that cooperation can evolve only under highly limited conditions, and various modifications have been introduced to games to explain the evolution of cooperation. Recently, a utility function basic to game theory was shown to be dependent on current wealth as a conditional (state) variable in a dynamic version of utility theory. Here, we introduce this dynamic utility function to several games. Under certain conditions, poor players exhibit cooperative behavior in two types of chicken games (the hawk-dove game and the snowdrift game) but not in the prisoner’s dilemma game and the stag hunt game. This result indicates that cooperation can be exhibited by the poor in some chicken games. Thus, the evolution of cooperation may not be as limited as has been suggested in previous studies.

    While trophy hunting provides revenue for conservation, it must be carefully managed to avoid negative population impacts, particularly for long-lived species with low natural mortality rates. Trophy hunting has had negative effects on lion populations throughout Africa, and the species serves as an important case study to consider the balance of costs and benefits, and to consider the effectiveness of alternative strategies to conserve exploited species. Age-restricted harvesting is widely recommended to mitigate negative effects of lion hunting, but this recommendation was based on a population model parameterized with data from a well-protected and growing lion population. Here, we used demographic data from lions subject to more typical conditions, including source-sink dynamics between a protected National Park and adjacent hunting areas in Zambia's Luangwa Valley, to develop a stochastic population projection model and evaluate alternative harvest scenarios. Hunting resulted in population declines over a 25-yr period for all continuous harvest strategies, with large declines for quotas >1 lion/concession (~0.5 lion/1,000 km(2) ) and hunting of males younger than seven years. A strategy that combined periods of recovery, an age limit of ≥7 yr, and a maximum quota of ~0.5 lions shot/1,000 km(2) yielded a risk of extirpation populations throughout Africa and to inform global efforts to conserve exploited carnivore populations.

  19. Isotopic evidence for Last Glacial climatic impacts on Neanderthal gazelle hunting territories at Amud Cave, Israel.

    2015-07-01

    The Middle Paleolithic site of Amud Cave, Israel, was occupied by Neanderthals at two different time periods, evidenced by two chronologically and stratigraphically distinct depositional sub-units (B4 and B2/B1) during MIS 4 and MIS 3, respectively. The composition of both hunted large fauna and naturally-deposited micromammalian taxa is stable at the site over time, despite a ∼ 10 ky gap between the two occupation phases. However, while gazelle is the most ubiquitous hunted species throughout the occupation, isotopic analysis showed that there is a marked change in Neanderthal hunting ranges between the early (B4) and late (B2/B1) phases. Hunting ranges were reconstructed by comparing oxygen, carbon, and strontium isotopes from gazelle tooth enamel with modern isotope data from the Amud Cave region. This region is characterized by extensive topographic, lithological, and pedological heterogeneity. During the early occupation phase negative oxygen isotope values, low radiogenic (87)Sr/(86)Sr ratios, and low Sr concentrations reveal restricted gazelle hunting in the high elevations west of Amud Cave. In the late occupation phase, hunting ranges became more diverse, but concentrate at low elevations closer to the site. Climatic proxies indicate that conditions were drier in the early occupation phase, which may have pushed gazelle populations into higher, more productive foraging areas. This study showed that Neanderthals adjusted their hunting territories considerably in relation to varying environmental conditions over the course of occupation in Amud Cave. It highlights the utility of multiple isotope analysis in enhancing the resolution of behavioral interpretations based on faunal remains and in reconstructing past hunting behaviors of Paleolithic hominins.

    Conservation of Neotropical game species must take into account the livelihood and food security needs of local human populations. Hunting management decisions should therefore rely on abundance and distribution data that are as representative as possible of true population sizes and dynamics. We simultaneously applied a commonly used encounter-based method and an infrequently used sign-based method to estimate hunted vertebrate abundance in a 48,000-km2 indigenous landscape in southern Guyana. Diurnal direct encounter data collected during three years along 216, four-kilometer -long transects consistently under-detected many diurnal and nocturnal mammal species readily detected through sign. Of 32 species analyzed, 31 were detected by both methods; however, encounters did not detect one and under-detected another 12 of the most heavily hunted species relative to sign, while sign under-detected 12 never or rarely collected species relative to encounters. The six most important game animals in the region, all ungulates, were not encountered at 11-40% of village and control sites or on 29-72% of transects where they were detected by sign. Using the sign methodology, we find that tapirs, one of the terrestrial vertebrates considered most sensitive to overexploitation, are present at many sites where they were never visually detected during distance sampling. We find that this is true for many other species as well. These high rates of under-detection suggest that behavioral changes in hunted populations may affect apparent occurrence and abundance of these populations. Accumulation curves (detection of species on transects) were much steeper for sign for 12 of 16 hunted species than for encounters, but that pattern was reversed for 12 of 16 species unhunted in our area. We conclude that collection of sign data is an efficient and effective method of monitoring hunted vertebrate populations that complements encounter and camera-trapping methods in areas impacted by

    Full Text Available Bushmeat hunting threatens biodiversity and increases the risk of zoonotic pathogen transmission. Nevertheless, limited information exists on patterns of contact with wildlife in communities that practice bushmeat hunting, especially with respect to social drivers of hunting behavior. We used interview responses from hunters and non-hunters in rural hunting communities in Nigeria to: 1 quantify contact rates with wildlife, 2 identify specific hunting behaviors that increase frequency of contact, 3 identify socioeconomic factors that predispose individuals to hunt, and 4 measure perceptions of risk. Participants engaged in a variety of behaviors that increased contact with wild animals, including: butchering to sell (37%, being injured (14%, using body parts for traditional medicine (19%, collecting carcasses found in forests and/or farms (18%, and keeping as pets (16%. Hunters came into contact with wildlife significantly more than non-hunters, even through non-hunting exposure pathways. Participants reported hunting rodents (95%, ungulates (93%, carnivores (93%, primates (87%, and bats (42%, among other prey. Reported hunting frequencies within taxonomic groups of prey were different for different hunting behaviors. Young age, lower education level, larger household size, having a father who hunts, and cultural group were all associated with becoming a hunter. Fifty-five percent of respondents were aware that they could contract diseases from wild animals, but only 26% of these individuals reported taking protective measures. Overall, hunters in this setting frequently contact a diversity of prey in risky ways, and the decision to become a hunter stems from family tradition, modified by economic necessity. Conservation and public health interventions in such settings may be most efficient when they capitalize on local knowledge and target root socio-economic and cultural drivers that lead to hunting behavior. Importantly, interventions that

    Gray wolves (Canis lupus) are managed for competing uses in the Greater Yellowstone Ecosystem (GYE). Tourism benefits Yellowstone National Park (YNP) visitors while trophy hunting benefits hunters outside of the park. We investigate the policy scope of gray wolf management across jurisdictional boundaries by incorporating three foundations of the behavioral ecology of wolves: refuge-seeking behavior, optimal foraging group size and territoriality. Tradeoffs between and within consumptive and non-consumptive human benefits and wolf population fitness and life history indicators are quantified as a set of elasticities, providing clear implications to resource managers. Our approach highlights that hunting intensity affects the provision of consumptive and non-consumptive human benefits across jurisdictional boundaries and ought to be managed accordingly. We also show that population levels are an incomplete indicator of species fitness, which may depend on how hunting policies impact underlying group ecology. Our findings suggest traditional optimization approaches to wildlife management may lead to suboptimal policy recommendations when the boundaries on the natural system are oversimplified. Highlighting the human element of wildlife management, we show that understanding tourist and hunter responses to wildlife population abundances is critical to balancing provision of consumptive and non-consumptive human uses.

    Zooarchaeological research at Qesem Cave, Israel demonstrates that large-game hunting was a regular practice by the late Lower Paleolithic period. The 400- to 200,000-year-old fallow deer assemblages from this cave provide early examples of prime-age-focused ungulate hunting, a human predator–prey relationship that has persisted into recent times. The meat diet at Qesem centered on large game and was supplemented with tortoises. These hominins hunted cooperatively, and consumption of the highest quality parts of large prey was delayed until the food could be moved to the cave and processed with the aid of blade cutting tools and fire. Delayed consumption of high-quality body parts implies that the meat was shared with other members of the group. The types of cut marks on upper limb bones indicate simple flesh removal activities only. The Qesem cut marks are both more abundant and more randomly oriented than those observed in Middle and Upper Paleolithic cases in the Levant, suggesting that more (skilled and unskilled) individuals were directly involved in cutting meat from the bones at Qesem Cave. Among recent humans, butchering of large animals normally involves a chain of focused tasks performed by one or just a few persons, and butchering guides many of the formalities of meat distribution and sharing that follow. The results from Qesem Cave raise new hypotheses about possible differences in the mechanics of meat sharing between the late Lower Paleolithic and Middle Paleolithic. PMID:19666542

    Full Text Available The risk for humans to contract bovine tuberculosis through the consumption of undercooked game meat as well as biltong (traditionally dried game meat is a concern. The survival potential of Mycobacterium bovis during the cooking and drying processes was researched in a preceding study on beef and the positive results compelled the authors to investigate the results with a similar preliminary study on game meat. Muscular, lymphatic and visceral tissues from skin test positive African buffalo (Syncerus caffer and greater kudu (Tragelaphus strepsiceros with tuberculous lesions were collected from the Hluhluwe iMfolozi Park during the park's culling programme. The different tissues were exposed to cooking and the muscular tissue to the drying process prior to culture. All acid-fast isolates were analysed by polymerase chain reaction for the presence of Mycobacterium bovis. All tissues were found negative for Mycobacterium bovis but non-tuberculous mycobacteria were isolated from kidney, liver, heart and lymph nodes. The results showed that these processes will kill Mycobacterium bovis but the unexpected recovery of non-tuberculous mycobacteria suggests possible survival and resistance characteristics of these strains which might be of veterinary public health interest.

  7. [New Developments in Video Games for Psychotherapy].

    2016-01-01

    A literature survey on new developments in the area of video games and psychotherapy of children and adolescents was conducted. Despite the omnipresence of computers and the internet, development of therapeutic games seems rather slow. The video game Treasure Hunt was introduced in 2008 to support treatment of children with internalizing and externalizing disorders. Camp Cope-A-Lot was developed for treatment of anxious children, whereas the self-help game SPARX is directed at depressed adolescents. Rage-Control is a biofeedback game for children with anger problems. The game Zoo U aims to assess and train social skills of primary school children. Ricky and the Spider for young children with obsessive compulsive disorder is meant to support the cognitive-behavioural treatment of these patients. Clash- Back is a French game for adolescents with externalizing problems. Possible reasons for the relatively slow development of therapeutic games are the high methodological demands concerning an evaluation as well as the high costs of game development. Nonetheless, computers and the internet are bound to influence psychotherapy with children and adolescents in the long run.

    The game statistics for the island of Olkiluoto were updated in the summer 2014 and compared with earlier statistics. In addition, the estimated biomass of hunted animals was calculated. The reported game bag and population size estimates are based on the annual action report of local hunting club (Olkiluodon Metsaestysseura ry) and interviews of hunting club's secretary. No moose or deer inventories were made in the winter 2013-2014. The moose population has been a slightly increasing when comparing the previous year; there were 4-6 individuals on the island after hunting season. The number of moose varies because they tend to move between the island and mainland. Winter 2013-2014 was relatively easy for white-tailed deer and roe deer but the predation caused by lynxes inhibits the increase of populations. However, the current amount of lynxes on the island is unknown because the lack of snow in the winter 2013-2014. In the summer of 2014, there were several lynx observations. The number of hunted raccoon dogs was almost four times as large as in the previous year; altogether 26 individuals were killed. There were no noticeable changes in the number of other hunted small or medium-sized predators. American minks were not killed at all. The total number of hunted hares decreased from eleven to seven. Once again, mallard was the most common hunted bird species followed by hooded crow. Other bird species hunted were wood pigeon, herring gull, hazel grouse, wigeon, teal and common pochard. The total biomass hunted was approximately 1 225 kilos (1 170 for mammals and 55 for birds) which was 305 kilos more than in the previous year. The biomass destined to human consumption (i.e. game meat) was approximately 415 kilos (400 kilos for mammals, 15 for birds). (orig.)

    The aim of this study was to measure lead (Pb) levels in blood (Pb-blood) in consumers of game meat, taking into account other possible sources of lead exposure. A spot blood sample was obtained from 95 subjects, and a questionnaire was used to collect general information and data on game meat consumption, hunting, wine drinking and other possible sources of lead exposure. Pb-blood was measured by inductively coupled plasma-mass spectrometry. Pb-blood was not influenced by age, sex, residence in an urban or rural area, consumption of game meat, tobacco smoking or hobbies associated with potential exposure to lead, and median Pb-blood was 1.7 (5th-95th percentile 1.0-5.3)µg/dL and 3.4 (0.9-6.1)µg/dL for game meat non-eaters and eater, respectively. A multiple linear regression analysis (containing the covariates sex, age, hunting, wine drinking, game meat consumption, tobacco smoking, shooting range, and occupational exposure) found an association with hunting (Pb-blood almost double in hunters) and wine drinking (40% higher in drinkers) but not with consumption of game meat or other parameters. Whether the higher Pb-blood level was due to inhalation of lead fumes while shooting with lead ammunition, to handling lead ammunition or both could not be ascertained. Copyright © 2017 Elsevier Inc.

    A subject of major importance in fundamental physics is the investigation of the origin of Electroweak Symmetry Breaking. The mechanism of mass generation through the spontaneous breaking of a gauge symmetry is called the Brout-Englert-Higgs mechanism and is associated with the appearance of a physical scalar boson. The discovery announced at CERN on 4th July 2012 by the ATLAS and CMS Collaborations of a boson at a mass close to 125 GeV/c2, compatible with this scalar boson of the Standard Model, the so-called Higgs boson, mainly in γγ, ZZ and WW decay modes, with compatible evidence also found at Fermilab in the bb mode, changed the landscape. This important discovery was acknowledged as decisive for the attribution of the 2013 Nobel Prize in Physics awarded jointly to François Englert and Peter Higgs . This 7th workshop of the "Higgs Hunting" series organized in Paris on August 31 - September 2, 2016 will discuss the developments of LHC run 2 analyses, detailed studies of the new boson and possible de...

    The digital revolution of the information age and in particular the sweeping changes of scientific communication brought about by computing and novel communication technology, potentiate global, high grade scientific information for free. The arXiv for example is the leading scientific communication platform, mainly for mathematics and physics, where everyone in the world has free access on. While in some scientific disciplines the open access way is successfully realized, other disciplines (e.g. humanities and social sciences) dwell on the traditional path, even though many scientists belonging to these communities approve the open access principle. In this paper we try to explain these different publication patterns by using a game theoretical approach. Based on the assumption, that the main goal of scientists is the maximization of their reputation, we model different possible game settings, namely a zero sum game, the prisoners' dilemma case and a version of the stag hunt game, that show the dilemma of sc...

  1. High risk of lead contamination for scavengers in an area with high moose hunting success.

    Top predators and scavengers are vulnerable to pollutants, particularly those accumulated along the food chain. Lead accumulation can induce severe disorders and alter survival both in mammals (including humans) and in birds. A potential source of lead poisoning in wild animals, and especially in scavengers, results from the consumption of ammunition residues in the tissues of big game killed by hunters. For two consecutive years we quantified the level lead exposure in individuals of a sentinel scavenger species, the common raven (Corvus corax), captured during the moose (Alces alces) hunting season in eastern Quebec, Canada. The source of the lead contamination was also determined using stable isotope analyses. Finally, we identified the different scavenger species that could potentially be exposed to lead by installing automatic cameras targeting moose gut piles. Blood lead concentration in ravens increased over time, indicating lead accumulation over the moose-hunting season. Using a contamination threshold of 100 µg x L(-1), more than 50% of individuals were lead-contaminated during the moose hunting period. Lead concentration was twice as high in one year compared to the other, matching the number of rifle-shot moose in the area. Non-contaminated birds exhibited no ammunition isotope signatures. The isotope signature of the lead detected in contaminated ravens tended towards the signature from lead ammunition. We also found that black bears (Ursus americanus), golden eagles and bald eagles (Aquila chrysaetos and Haliaeetus leucocephalus, two species of conservation concern) scavenged heavily on moose viscera left by hunters. Our unequivocal results agree with other studies and further motivate the use of non-toxic ammunition for big game hunting.

  2. High risk of lead contamination for scavengers in an area with high moose hunting success.

    Pierre Legagneux

    Full Text Available Top predators and scavengers are vulnerable to pollutants, particularly those accumulated along the food chain. Lead accumulation can induce severe disorders and alter survival both in mammals (including humans and in birds. A potential source of lead poisoning in wild animals, and especially in scavengers, results from the consumption of ammunition residues in the tissues of big game killed by hunters. For two consecutive years we quantified the level lead exposure in individuals of a sentinel scavenger species, the common raven (Corvus corax, captured during the moose (Alces alces hunting season in eastern Quebec, Canada. The source of the lead contamination was also determined using stable isotope analyses. Finally, we identified the different scavenger species that could potentially be exposed to lead by installing automatic cameras targeting moose gut piles. Blood lead concentration in ravens increased over time, indicating lead accumulation over the moose-hunting season. Using a contamination threshold of 100 µg x L(-1, more than 50% of individuals were lead-contaminated during the moose hunting period. Lead concentration was twice as high in one year compared to the other, matching the number of rifle-shot moose in the area. Non-contaminated birds exhibited no ammunition isotope signatures. The isotope signature of the lead detected in contaminated ravens tended towards the signature from lead ammunition. We also found that black bears (Ursus americanus, golden eagles and bald eagles (Aquila chrysaetos and Haliaeetus leucocephalus, two species of conservation concern scavenged heavily on moose viscera left by hunters. Our unequivocal results agree with other studies and further motivate the use of non-toxic ammunition for big game hunting.

  3. Game Theory with Costly Computation

    Halpern, Joseph Y

    2008-01-01

    We develop a general game-theoretic framework for reasoning about strategic agents performing possibly costly computation. In this framework, many traditional game-theoretic results (such as the existence of a Nash equilibrium) no longer hold. Nevertheless, we can use the framework to provide psychologically appealing explanations to observed behavior in well-studied games (such as finitely repeated prisoner's dilemma and rock-paper-scissors). Furthermore, we provide natural conditions on games sufficient to guarantee that equilibria exist. As an application of this framework, we consider a notion of game-theoretic implementation of mediators in computational games. We show that a special case of this notion is equivalent to a variant of the traditional cryptographic definition of protocol security; this result shows that, when taking computation into account, the two approaches used for dealing with "deviating" players in two different communities -- Nash equilibrium in game theory and zero-knowledge "simula...

  5. The management of hunting of Anatidae

    Science.gov (United States)

    Nichols, J.D.; Johnson, F.A.; Birkan, Marcel

    1996-01-01

    The objectives of harvest management for members of family Anatidae typically involve the size of the harvested population and the size of the harvest. Hunting regulations are the primary tool used to try to achieve the objectives of harvest management. Informed harvest management thus requires a knowledge of the relationship between hunting regulations and both Anatid abundance and harvest. Results of retrospective studies in North America provide evidence that generally restrictive regulations produce lower harvest rates than generally liberal regulations. However, such studies have provided little evidence that specific hunting regulations designed to produce a change in the relative harvest rates of different species, or of the sexes within a species, have been successful in 'directing' harvest toward specific groups of birds and away from other groups. Estimates of the strength of the relationship between harvest mortality rates and annual survival rates of Anatidae have ranged from weak to strong. Thus, the key relationships for harvest management of Anatidae, those between hunting regulations and the size of both the subsequent harvest and the subsequent population, are not 'known' but are characterized by uncertainty. In the United States, this uncertainty led to a risk-aversive conservatism that characterized the setting of hunting regulations during the last decade. Recently, managers have begun to consider using hunting regulations themselves as a means to better understand the system being managed. This approach, referred to as active adaptive management, attempts to balance short-term demands for hunting opportunity with the learning needed to improve long-term management performance. Learning is accomplished by periodically comparing observed system response, as estimated by ongoing survey and data collection programs, with predictions of competing models. These periodic comparisons lead to changes in measures of credibility associated with the

  6. Human Hunting and Nascent Animal Management at Middle Pre-Pottery Neolithic Yiftah'el, Israel.

    Directory of Open Access Journals (Sweden)

    Lidar Sapir-Hen

    Full Text Available The current view for the southern Levant is that wild game hunting was replaced by herd management over the course of the Pre-Pottery Neolithic B period, but there is significant debate over the timing, scale and origin of this transition. To date, most relevant studies focus either on wild game exploitation in the periods prior to domestication or on classic markers of domestication of domestic progenitor species over the course of the PPNB. We studied the faunal remains from the 2007-2008 excavations of the Middle PPNB (MPPNB site of Yiftah'el, Northern Israel. Our analysis included a close examination of the timing and impact of the trade-off between wild game and domestic progenitor taxa that reflects the very beginning of this critical transition in the Mediterranean zone of the southern Levant. Our results reveal a direct trade-off between the intensive hunting of wild ungulates that had been staples for millennia, and domestic progenitor taxa. We suggest that the changes in wild animal use are linked to a region-wide shift in the relationship between humans and domestic progenitor species including goat, pig and cattle.

    2004-03-11

    In most species, sport hunting of male trophy animals can only reduce overall population size when the rate of removal of males is so high that females can no longer be impregnated. However, where males provide extensive paternal care, the removal of even a few individuals could harm the population as a whole. In species such as lions, excessive trophy hunting could theoretically cause male replacements (and associated infanticide) to become sufficiently common to prevent cubs reaching adulthood. Here we simulate the population consequences of lion trophy hunting using a spatially explicit, individual-based, stochastic model parameterized with 40 years of demographic data from northern Tanzania. Although our simulations confirm that infanticide increases the risk of population extinction, trophy hunting could be sustained simply by hunting males above a minimum age threshold, and this strategy maximizes both the quantity and the quality of the long-term kill. We present a simple non-invasive technique for estimating lion age in populations lacking long-term records, and suggest that quotas would be unnecessary in any male-only trophy species where age determination could be reliably implemented.

    Even when hunting in groups is mutually beneficial, it is unclear how communal hunts are initiated. If it is costly to be the only hunter, individuals should be reluctant to hunt unless others already are. We used 70 years of data from three communities to examine how male chimpanzees 'solve' this apparent collective action problem. The 'impact hunter' hypothesis proposes that group hunts are sometimes catalysed by certain individuals that hunt more readily than others. In two communities (Kasekela and Kanyawara), we identified a total of five males that exhibited high hunt participation rates for their age, and whose presence at an encounter with red colobus monkeys increased group hunting probability. Critically, these impact hunters were observed to hunt first more often than expected by chance. We argue that by hunting first, these males dilute prey defences and create opportunities for previously reluctant participants. This by-product mutualism can explain variation in group hunting rates within and between social groups. Hunting rates declined after the death of impact hunter FG in Kasekela and after impact hunter MS stopped hunting frequently in Kanyawara. There were no impact hunters in the third, smaller community (Mitumba), where, unlike the others, hunting probability increased with the number of females present at an encounter with prey.

    The purpose of this article is to analyze the South Korea and China of computer game research, and the current state of research in Japan. Excessive game actions were analyzed by PET-MRI, MRI, fMRI, NIRS, EEG. These results showed that the prefrontal cortical activity decreased during game play. Also, game addiction causes damage to the prefrontal cortex. The NIRS-EEG and simultaneous recording, during game play correspond well with the decrease of β band and oxygen-hemoglobin. The α band did not change with game play. However, oxygen-hemoglobin decreased during game play. South Korea, game addiction measures have been analyzed since 2002, but in Japan the research is recent.

    To compare upper limb kinematics of children with spastic cerebral palsy (CP) using a passive rehabilitation joystick with those of adults and able-bodied children, to better understand the design requirements of computer-based rehabilitation devices. A blocked comparative study involving seven children with spastic CP, nine able-bodied adults and nine able-bodied children, using a joystick system to play a computer game whilst the kinematics of their upper limb were recorded. The translational kinematics of the joystick's end point and the participant's shoulder movement (protraction/retraction) and elbow rotational kinematics (flexion/extension) were analysed for each group. Children with spastic CP matched their able-bodied peers in the time taken to complete the computer task, but this was due to a failure to adhere to the task instructions of travelling along a prescribed straight line when moving between targets. The spastic CP group took longer to initiate the first movement, which showed jerkier trajectories and demonstrated qualitatively different movement patterns when using the joystick, with shoulder movements that were significantly of greater magnitude than the able-bodied participants. Children with spastic CP generate large shoulder and hence trunk movements when using a joystick to undertake computer-generated arm exercises. This finding has implications for the development and use of assistive technologies to encourage exercise and the instructions given to users of such systems. A kinematic analysis of upper limb function of children with CP when using joystick devices is presented. Children with CP may use upper body movements to compensate for limitations in voluntary shoulder and elbow movements when undertaking computer games designed to encourage the practice of arm movement. The design of rehabilitative computer exercise systems should consider movement of the torso/shoulder as it may have implications for the quality of therapy in the

  16. Asymmetric Evolutionary Games.

    Directory of Open Access Journals (Sweden)

    Alex McAvoy

    2015-08-01

    Full Text Available Evolutionary game theory is a powerful framework for studying evolution in populations of interacting individuals. A common assumption in evolutionary game theory is that interactions are symmetric, which means that the players are distinguished by only their strategies. In nature, however, the microscopic interactions between players are nearly always asymmetric due to environmental effects, differing baseline characteristics, and other possible sources of heterogeneity. To model these phenomena, we introduce into evolutionary game theory two broad classes of asymmetric interactions: ecological and genotypic. Ecological asymmetry results from variation in the environments of the players, while genotypic asymmetry is a consequence of the players having differing baseline genotypes. We develop a theory of these forms of asymmetry for games in structured populations and use the classical social dilemmas, the Prisoner's Dilemma and the Snowdrift Game, for illustrations. Interestingly, asymmetric games reveal essential differences between models of genetic evolution based on reproduction and models of cultural evolution based on imitation that are not apparent in symmetric games.

    The pollution of wetlands by lead derived from waterfowl hunting with lead shot was investigated. We determined soil pellet density and Pb concentration in soil, water and vegetation in natural wetlands and rice fields in central-eastern Santa Fe province, Argentina. Pellet density varied greatly among hunting sites (between 5.5-141 pellets/m(2)) and pellets were present in some control sites. Soil Pb concentration in most hunting sites (approximately 10-20 mg kg(-1)) was not much higher than in control sites (~5-10 mg kg(-1)), with the exception of the site with highest pellet density, which also had a high Pb soil concentration. In water, on the other hand, Pb concentration was similar in all sites (~4-7 μg L(-1)), both control and hunting, and higher than reference values for aquatic media. Lead was also present in vegetation, including grasses and rice crops, in almost all cases. Most soil-collection sites were slightly acidic, and were frequently flooded. These results strongly suggest that metallic Pb from spent shot is oxidized and dissolved due to wetland conditions. Thus, the pollutant is readily mobilized and distributed across all wetland areas, effectively homogenizing its concentration in locations with and without hunting activities. The replacement of lead by nontoxic materials in pellets appears to be the only effective way to prevent Pb pollution in wetlands.

    Hunting cheetah reportedly store metabolic heat during the chase and abandon chases because they overheat. Using biologging to remotely measure the body temperature (every minute) and locomotor activity (every 5 min) of four free-living cheetah, hunting spontaneously, we found that cheetah abandoned hunts, but not because they overheated. Body temperature averaged 38.4°C when the chase was terminated. Storage of metabolic heat did not compromise hunts. The increase in body temperature following a successful hunt was double that of an unsuccessful hunt (1.3°C ± 0.2°C versus 0.5°C ± 0.1°C), even though the level of activity during the hunts was similar. We propose that the increase in body temperature following a successful hunt is a stress hyperthermia, rather than an exercise-induced hyperthermia.

    We consider a hunting area and a wildlife reserve and answer the question: How does clever migration decision affect the social optimal and the private optimal hunting levels and population stocks? We analyze this in a model allowing for two-way migration between hunting and reserve areas, where...... the populations’ migration decisions depend on both hunting pressure and relative population densities. In the social optimum a pure stress effect on the behavior of smart wildlife exists. This implies that the population level in the wildlife reserve tends to increase and the population level in the hunting area...... and hunting levels tend to decrease. On the other hand, the effect on stock tends to reduce the population in the wildlife reserve and increase the population in the hunting area and thereby also increase hunting. In the case of the private optimum, open-access is assumed and we find that the same qualitative...

  10. Quantum Game Theory Based on the Schmidt Decomposition: Can Entanglement Resolve Dilemmas?

    CERN Document Server

    Ichikawa, T; Tsutsui, I; Cheon, Taksu; Ichikawa, Tsubasa; Tsutsui, Izumi

    2007-01-01

    We present a novel formulation of quantum game theory based on the Schmidt decomposition, which has the merit that the entanglement of quantum strategies is manifestly quantified. We apply this formulation to 2-player, 2-strategy symmetric games and obtain a complete set of quantum Nash equilibria. Apart from those available with the maximal entanglement, these quantum Nash equilibria are extensions of the Nash equilibria in classical game theory. The phase structure of the equilibria is determined for all values of entanglement, and thereby the possibility of resolving the dilemmas by entanglement in the game of Chicken, the Battle of the Sexes, the Prisoners' Dilemma, and the Stag Hunt, is examined. We find that entanglement transforms these dilemmas with each other but cannot resolve them, except in the Stag Hunt game where the dilemma can be alleviated to a certain degree.

  12. Cat Dilemma: Too Protected To Escape Trophy Hunting?

    OpenAIRE

    2011-01-01

    Trophy hunting is one of the most controversial issues in the field of biodiversity conservation. In particular, proponents and opponents debate fiercely over whether it poses a threat to hunted populations. Here, we show that trophy hunting constitutes a greater menace to threatened species than previously realized. Because humans value rarity, targeted species that are threatened are likely to be disproportionately hunted, thereby becoming even more vulnerable, which could eventually push t...

  13. Pervasive Gaming: Formats, Rules, And Space

    Directory of Open Access Journals (Sweden)

    Bo Kampmann Walther

    2006-01-01

    Full Text Available Pervasive Gaming (PG denotes a noteworthy change in the history and nature of computer games. By intentionally merging virtual and physical space, pervasive gaming not only extends the magic circle of play; it further challenges our conception of game rules, game mechanics, and game entities. This paper introduces and discusses some of the key characteristics of this novel trend in computer games. Following a short description of the significant features of pervasive computing, Walther explicates pervasive gaming in relation to time, space, and presence (or immersion. Then I position four axes or zones of pervasive gaming: mobility, distribution, persistence, and transmediality. Further, I describe and analyse three essential units of PG (rules, entities, and mechanics, and finally, I speculate about the role of space in PG by differentiating between tangible space, information space, and accessibility space.

    Conservation scientists are increasingly focusing on the drivers of human behavior and on the implications of various sources of uncertainty for management decision making. Trophy hunting has been suggested as a conservation tool because it gives economic value to wildlife, but recent examples show that overharvesting is a substantial problem and that data limitations are rife. We use a case study of trophy hunting of an endangered antelope, the mountain nyala (Tragelaphus buxtoni), to explore how uncertainties generated by population monitoring and poaching interact with decision making by 2 key stakeholders: the safari companies and the government. We built a management strategy evaluation model that encompasses the population dynamics of mountain nyala, a monitoring model, and a company decision making model. We investigated scenarios of investment into antipoaching and monitoring by governments and safari companies. Harvest strategy was robust to the uncertainty in the population estimates obtained from monitoring, but poaching had a much stronger effect on quota and sustainability. Hence, reducing poaching is in the interests of companies wishing to increase the profitability of their enterprises, for example by engaging community members as game scouts. There is a threshold level of uncertainty in the population estimates beyond which the year-to-year variation in the trophy quota prevented planning by the safari companies. This suggests a role for government in ensuring that a baseline level of population monitoring is carried out such that this level is not exceeded. Our results illustrate the importance of considering the incentives of multiple stakeholders when designing frameworks for resource use and when designing management frameworks to address the particular sources of uncertainty that affect system sustainability most heavily.

  8. Hunting Elusive SPRITEs with Spitzer

    Science.gov (United States)

    Kohler, Susanna

    2017-05-01

    In recent years, astronomers have developed many wide-field imaging surveys in which the same targets are observed again and again. This new form of observing has allowed us to discover optical and radio transients explosive or irregular events with durations ranging from seconds to years. The dynamic infrared sky, however, has remained largely unexplored until now.Infrared ExplorationExample of a transient: SPIRITS 14ajc was visible when imaged by SPIRITS in 2014 (left) but it wasnt there during previous imaging between 2004 and 2008 (right). The bottom frame shows the difference between the two images. [Adapted from Kasliwal et al. 2017]Why hunt for infrared transients? Optical wavelengths dont allow us to observe events that are obscured, such that their own structure or their surroundings hide them from our view. Both supernovae and luminous red novae (associated with stellar mergers) are discoverable as infrared transients, and there may well be new types of transients in infrared that we havent seen before!To explore this uncharted territory, a team of scientists developed SPIRITS, the Spitzer Infrared Intensive Transients Survey. Begun in 2014, SPIRITS is a five-year long survey that uses the Spitzer Space Telescope to conduct a systematic search for mid-infrared transients in nearby galaxies.In a recent publication led by Mansi Kasliwal (Caltech and the Carnegie Institution for Science), the SPIRITS team has now detailed how their survey works and what theyve discovered in its first year.The light curves of SPRITEs (red stars) lie in the mid-infared luminosity gap between novae (orange) and supernovae (blue). [Kasliwal et al. 2017]Mystery TransientsKasliwal and collaborators used Spitzer to monitor 190 nearby galaxies. In SPIRITS first year, they found over 1958 variable stars and 43 infrared transient sources. Of these 43 transients, 21 were known supernovae, 4 were in the luminosity range of novae, and 4 had optical counterparts. The remaining 14 events

    Phenotype-based selective harvests, including trophy hunting, can have important implications for sustainable wildlife management if they target heritable traits. Here we show that in an evolutionary response to sport hunting of bighorn trophy rams (Ovis canadensis) body weight and horn size have declined significantly over time. We used quantitative genetic analyses, based on a partly genetically reconstructed pedigree from a 30-year study of a wild population in which trophy hunting targeted rams with rapidly growing horns, to explore the evolutionary response to hunter selection on ram weight and horn size. Both traits were highly heritable, and trophy-harvested rams were of significantly higher genetic 'breeding value' for weight and horn size than rams that were not harvested. Rams of high breeding value were also shot at an early age, and thus did not achieve high reproductive success. Declines in mean breeding values for weight and horn size therefore occurred in response to unrestricted trophy hunting, resulting in the production of smaller-horned, lighter rams, and fewer trophies.

    DEFF Research Database (Denmark)

    2015-01-01

    When we play games of any kind, from tennis to board games, it is easy to notice that games seem to be configured in space, often using stripes or a kind of map on a board. Some games are clearly performed within this marked border, while it may be difficult to pinpoint such a border in games like...... hide-and-seek, but even these games are still spatially configured. The border (visible or not) both seem to separate and uphold the game that it is meant for. This chapter sets out to analyse the possible border that separates a game from the surrounding world. Johan Huizinga noted this “separateness......” in his classic work “Homo Ludens” (Huizinga 1938, translated into English 1971). This has since been developed into the concept of the “magic circle” by Salen and Zimmerman (2003), as an understanding of playing games as a kind of alternate reality. When a person cross the magic circle of a game, he...

    CERN Document Server

    Neeman, Itay

    2004-01-01

    In this volume the author develops and applies methods for proving, from large cardinals, the determinacy of definable games of countable length on natural numbers. The determinacy is ultimately derived from iteration strategies, connecting games on natural numbers with the specific iteration games that come up in the study of large cardinals. The games considered in this text range in strength, from games of fixed countable length, through games where the length is clocked by natural numbers, to games in which a run is complete when its length is uncountable in an inner model (or a pointclass) relative to the run. More can be done using the methods developed here, reaching determinacy for games of certain length. The book is largely self-contained. Only graduate level knowledge of modern techniques in large cardinals and basic forcing is assumed. Several exercises allow the reader to build on the results in the text, for example connecting them with universally Baire and homogeneously Suslin sets. - Importan...

    2012-01-01

    Serum and blood samples from 36 game animals, shot during the hunting seasons 2007-2009, were collected and analyzed for the presence of Trypanosoma spp. by three methods: isolation, polymerase chain reaction (PCR), and serology. Only fissiped animals were included, four different ruminants and wild boar. Trypanosomes could be isolated from two of the animals, and eight had detectable parasite DNA. Seven animals had high titers of anti-trypanosoma IgG antibodies. The two isolated strains, one from roe dear and one from European elk, were determined to Trypanosoma theileri by partial DNA sequencing of the 18S ribosomal gene. In the seven boars, no Trypanosoma were detected, but four out of seven strongly positive serological samples came from this group. This is the first study in Scandinavia on the presence of Trypanosoma in game animals. The results indicate that trypanosomiasis is frequently occurring among Swedish game animals.

    2014-12-01

    It seems a universal phenomenon of networks that the attacks on a small number of nodes by an adversary player Alice may generate a global cascading failure of the networks. It has been shown (Li et al., 2013) that classic scale-free networks (Barabási and Albert, 1999, Barabási, 2009) are insecure against attacks of as small as O(logn) many nodes. This poses a natural and fundamental question: Can we introduce a second player Bob to prevent Alice from global cascading failure of the networks? We proposed a game in networks. We say that a network has an equilibrium game if the second player Bob has a strategy to balance the cascading influence of attacks by the adversary player Alice. It was shown that networks of the preferential attachment model (Barabási and Albert, 1999) fail to have equilibrium games, that random graphs of the Erdös-Rényi model (Erdös and Rényi, 1959, Erdös and Rényi, 1960) have, for which randomness is the mechanism, and that homophyly networks (Li et al., 2013) have equilibrium games, for which homophyly and preferential attachment are the underlying mechanisms. We found that some real networks have equilibrium games, but most real networks fail to have. We anticipate that our results lead to an interesting new direction of network theory, that is, equilibrium games in networks.

  2. Games are motivating, aren´t they? Disputing the arguments for digital game-based learning

    Directory of Open Access Journals (Sweden)

    Wim Westera

    2015-06-01

    Full Text Available The growing popularity of game-based learning reflects the burning desire for exploiting the involving and motivating characteristics of games for serious purposes. A wide range of arguments for using games for teaching and learning can be encountered in scientific papers, policy reports, game reviews and advertisements. With contagious enthusiasm, the proponents of game-based learning make their claims for using games to improve education. However, standing up for a good cause is easily replaced with the unconcerned promotion and spread of the word, which tends to make gaming an article of faith. This paper critically examines and re-establishes the argumentation used for game-based learning and identifies misconceptions that confuse the discussions. It reviews the following claims about game-based learning: 1 games foster motivation, 2 play is a natural mode of learning, 3 games induce cognitive flow, which is productive for learning, 4 games support learning-by-doing, 5 games allow for performance monitoring, 6 games offer freedom of movement and the associated problem ownership, 7 games support social learning, 8 games allow for safe experimentation, 9 games accommodate new generations of learners, who have grown up immersed in digital media, and 10 there are many successful games for learning. Assessing the validity of argumentation is considered essential for the credibility of game-based learning as a discipline.

  3. Positional games

    Hefetz, Dan; Stojaković, Miloš; Szabó, Tibor

    2014-01-01

    This text serves as a thorough introduction to the rapidly developing field of positional games. This area constitutes an important branch of combinatorics, whose aim it is to systematically develop an extensive mathematical basis for a variety of two-player perfect information games. These range from such popular games as Tic-Tac-Toe and Hex to purely abstract games played on graphs and hypergraphs. The subject of positional games is strongly related to several other branches of combinatorics such as Ramsey theory, extremal graph and set theory, and the probabilistic method. These notes cover a variety of topics in positional games, including both classical results and recent important developments. They are presented in an accessible way and are accompanied by exercises of varying difficulty, helping the reader to better understand the theory. The text will benefit both researchers and graduate students in combinatorics and adjacent fields.

  16. Post–breeding movements and migration patterns of western populations of common quail (Coturnix coturnix: from knowledge to hunting management

    Full Text Available We investigated the patterns of post–breeding movements of the common quail (Coturnix coturnix in the Iberian peninsula with the aim of describing its migratory phenology and some physiological features of individuals. This information is needed to adjust hunting seasons in an optimal way. We worked with two data–sets: a captures made in a non–breeding site (Garraf from August to October in 2009 and 2010; b post–breeding recoveries of individuals ringed in Europe and recaptured in Spain between 1933 and 2005. The results showed that post–breeding movements in Garraf occur in two waves: a first wave that occurs around 10 VIII and is mainly composed of non–sexually active yearlings that do not correspond physiologically to migrants, and a second much more intense wave, which occurs around 17 IX and is mainly composed of non–sexually active migrant yearlings. The hunting season in Spain takes place mainly during the first wave, preserving the passage of migrant individuals from Spain and other European countries. Information on the post–breeding movements in other Spanish regions and other European countries where the common quail is a popular game species would improve timing between the hunting season and migration by providing more precise recommendations for hunting management.

  18. Rapid evolution in the wild: changes in body size, life-history traits, and behavior in hunted populations of the Japanese mamushi snake.

    Sasaki, Kiyoshi; Fox, Stanley F; Duvall, David

    2009-02-01

    Rapid evolution caused by human exploitation of wildlife is not usually addressed in studies of the impacts of such exploitation despite its direct relevance to population persistence. Japanese mamushi (Gloydius blomhoffii), an endemic venomous snake of the Japanese archipelago, has been heavily hunted by humans, and many populations appear to be declining or are already extirpated. We compared local populations that have been hunted regularly with populations that have not been hunted. Mamushi in hunted populations were smaller, had fewer vertebrae, produced more and smaller offspring, had increased reproductive effort among smaller females, and in nature fled at greater distances from an approaching human and were less defensive than mamushi in unhunted populations, as predicted from life-history theory. Heritability estimates for body size, number of vertebrae, and antipredator behavior were statistically significant, and neonates from hunted sites showed the same distribution of altered characters (compared with those from unhunted sites) as adults. Thus, distribution of the divergent trait between hunted and unhunted sites appeared in part to be genetically based, which suggests rapid evolution to human predation pressures. Trait distributions in hunted populations probably deviate from naturally (as opposed to anthropogenically) selected optima and, therefore, may have long-term negative repercussions on population persistence. Because rapid evolution affects a suite of parameters that characterize exploited populations, accurate understanding of the impacts of exploitation and effective resource management and conservation can only be achieved if evolutionary consequences are considered explicitly.

  19. Identity-driven differences in stakeholder concerns about hunting wolves.

    2014-01-01

    Whereas past wolf management in the United States was restricted to recovery, managers must now contend with publicly contentious post-recovery issues including regulated hunting seasons. Understanding stakeholder concerns associated with hunting can inform stakeholder engagement, communication, and policy development and evaluation. Social identity theory (SIT) has been used to understand how groups interact, why they conflict, and how collaboration may be achieved. Applying SIT to stakeholder conflicts about wolf hunting may help delineate groups according to their concern about, support for or opposition to the policy choice of hunting wolves. Our objective was to assess concerns about hunting as a tool to resolve conflict in Michigan, using SIT as a framework. We used a mixed-modal sampling approach (e.g., paper, Internet) with wolf hunting-related public meeting participants in March 2013. Survey questions focused on 12 concerns previously identified as associated with hunting as a management tool to resolve conflict. Respondents (n  =  666) cared greatly about wolves but were divided over hunting wolves. Wolf conflicts, use of science in policy decisions, and maintaining a wolf population were the highest ranked concerns. Principle components analysis reduced concerns into three factors that explained 50.7% of total variance; concerns crystallized over justifications for hunting. General linear models revealed a lack of geographic influence on care, fear and support for hunting related to wolves. These findings challenge assumptions about regional differences and suggest a strong role for social identity in driving dichotomized public perceptions in wildlife management.

    Chappell, James M; Iqbal, Azhar; Abbott, Derek

    2012-01-01

    The framework for playing quantum games in an Einstein-Podolsky-Rosen (EPR) type setting is investigated using the mathematical formalism of geometric algebra (GA). The main advantage of this framework is that the players' strategy sets remain identical to the ones in the classical mixed-strategy version of the game, and hence the quantum game becomes a proper extension of the classical game, avoiding a criticism of other quantum game frameworks. We produce a general solution for two-player games, and as examples, we analyze the games of Prisoners' Dilemma and Stag Hunt in the EPR setting. The use of GA allows a quantum-mechanical analysis without the use of complex numbers or the Dirac Bra-ket notation, and hence is more accessible to the non-physicist.

    2016-11-16

    We present evidence of a novel form of group hunting. Individual sailfish (Istiophorus platypterus) alternate attacks with other group members on their schooling prey (Sardinella aurita). While only 24% of attacks result in prey capture, multiple prey are injured in 95% of attacks, resulting in an increase of injured fish in the school with the number of attacks. How quickly prey are captured is positively correlated with the level of injury of the school, suggesting that hunters can benefit from other conspecifics' attacks on the prey. To explore this, we built a mathematical model capturing the dynamics of the hunt. We show that group hunting provides major efficiency gains (prey caught per unit time) for individuals in groups of up to 70 members. We also demonstrate that a free riding strategy, where some individuals wait until the prey are sufficiently injured before attacking, is only beneficial if the cost of attacking is high, and only then when waiting times are short. Our findings provide evidence that cooperative benefits can be realized through the facilitative effects of individuals' hunting actions without spatial coordination of attacks. Such 'proto-cooperation' may be the pre-cursor to more complex group-hunting strategies.

    The use of Natural Gas is nowadays increasing in Brazilian scene and this fact shows the necessity of effective planning tasks in that sector. In the case of Natural Gas Vehicular (NGV) distribution one can face problems of actor's (distributor, retailers, customers and non-users) point of view conflicts and fuel stations expand in most Brazilian urban areas in an uncontrolled way, despising counties regulation on land use. This paper reports a study using a model based in Game Theory concepts to determine some key-variables as the number of fuel stations which must deliver NGV in a given study area. Although some information could not be available the results of simulation shows the usefulness of using such an approach to give solutions to distribution questions in NGV sector. The model was applied to the case of a district in Fortaleza city which is the study area of a project entitled Projeto GASLOG presently on process under the sponsoring of Brazilian Government, PETROBRAS and Brazilian GasEnergy Research Network.

    Mutual imitation games among artificial birds are studied. By employing a variety of mappings and game rules, the evolution to the edge between chaos and windows is universally confirmed. Some other general features are observed, including punctuated equilibria, and successive alternations of dominant species with temporal complexity. Diversity of species aided by the symbolization of artificial birds' song are also shown.

  5. An application of evolutionary game theory to social dilemmas: the traveler's dilemma and the minimum effort coordination game.

    Directory of Open Access Journals (Sweden)

    Swami Iyer

    Full Text Available The Traveler's Dilemma game and the Minimum Effort Coordination game are two social dilemmas that have attracted considerable attention due to the fact that the predictions of classical game theory are at odds with the results found when the games are studied experimentally. Moreover, a direct application of deterministic evolutionary game theory, as embodied in the replicator dynamics, to these games does not explain the observed behavior. In this work, we formulate natural variants of these two games as smoothed continuous-strategy games. We study the evolutionary dynamics of these continuous-strategy games, both analytically and through agent-based simulations, and show that the behavior predicted theoretically is in accord with that observed experimentally. Thus, these variants of the Traveler's Dilemma and the Minimum Effort Coordination games provide a simple resolution of the paradoxical behavior associated with the original games.

    The purpose of this study is to explore how an online-structured dialogue environment supported (OSDE) collaborative learning about the nature of science among a group of trainee science teachers in the UK. The software used (InterLoc) is a linear text-based tool, designed to support structured argumentation with openers and `dialogue moves'. A design-based research approach was used to investigate multiple sessions using InterLoc with 65 trainee science teachers. Five participants who showed differential conceptual change in terms of their Nature of Science (NOS) views were purposively selected and closely followed throughout the study by using key event recall interviews. Initially, the majority of participants held naïve views of NOS. Substantial and favourable changes in these views were evident as a result of the OSDE. An examination of the development of the five participants' NOS views indicated that the effectiveness of the InterLoc discussions was mediated by cultural, cognitive, and experiential factors. The findings suggest that InterLoc can be effective in promoting reflection and conceptual change.

  11. Adhesive foot pads: an adaptation to climbing? An ecological survey in hunting spiders.

    Wolff, Jonas O; Gorb, Stanislav N

    2015-02-01

    Hairy pads relying on dry adhesion are fascinating structures that convergently evolved among spiders and lizards. Numerous studies underline the functional aspects leading to their strong adhesion to smooth surfaces, but rarely has their role been studied in the context of natural habitats and surfaces that animals are faced with. In hunting spiders, the hairy foot pads (claw tufts) underneath the paired claws are assumed to be an adaptation to a climbing lifestyle, particularly on smooth plant surfaces. However, surfaces that are too smooth for claws to generate a sufficient grip are rather rare in natural habitats and above-ground habitats are occupied by hunting spiders both with and without claw tufts. In this study we estimated the proportion of claw tuft-bearing hunting spiders (ct+ ratio) among microhabitat-specific assemblages by conducting both a field study and a meta-analysis approach. The effect of surface characteristics, structure fragmentation and altitude of the microhabitat niche on the ct+ ratio was analyzed. We hypothesized that the ct+ ratio will be higher in (i) hunting spider assemblages obtained from microhabitats above the ground than from those at the ground and (ii) in hunting spider assemblages obtained from microhabitats with smoother surfaces (tree foliage) than those with rougher surfaces (barks, stones), and lower in (iii) hunting spider assemblages obtained from microhabitats with more fragmented structures (small leaves) than in those with comparable but less fragmented structures (large leaves). We found the ct+ ratio to be significantly affected by the microhabitat's distance from the ground, whereas surface characteristics and fragmentation of the substrates were of minor importance. This suggests that claw tufts are highly beneficial when the microhabitat's height exceeds a value where the additional pad-related costs are exceeded by the costs of dropping. We assume the benefit to be mainly due to gaining a high safety factor

    Niklas Schrape

    2014-09-01

    Full Text Available James Lovelock’s vision of Earth as a living cybernetic system is popular again. The surprising new preacher of Gaia is Bruno Latour. He uses the concept to refer to a holistic understanding of Earth, in which mankind is situated as integral part. Gaia becomes the catalyst and fundament for his philosophical attempt to design a new believe-system in the time of ecological crisis. But the concept of Gaia is characterised by a tension between the idea of a powerful but indifferent nature and a grandiose vision of total control over it. This tension reveals itself to be deeply rooted in cybernetic thought. It is not only apparent in Lovelock’s own writing, but also in simulation programs based on the Gaia hypothesis such as the Daisyworld model and the computer game “SimEarth: The Living Planet” (1991. The article will distinguish Lovelock’s from Latour’s concept of Gaia and relate them to first- and second order cybernetics as well as to two different approaches to computer simulation: system dynamics and cellular automata.

  13. Immersion in narrative games

    Suely Fragoso

    2014-12-01

    Full Text Available This paper discusses the expressions used to refer to the experience of immersive in narrative games. The starting point is a review of the meanings associated with the suspension of disbelief in literature, cinema and television, challenging the myth of the naïve audience that cannot distinguish between representation and reality. Two characteristics of interactive media narratives – the possibility of agency and the disparities between hardware and software interfaces – reveal the active nature of the audience’s involvement with media representations. It is proposed that, in the case of games, this ability, which allows for simultaneous actions in the world of games and in the real world, is better described as a performance of belief.

  20. Evolving hunting practices in Gabon: lessons for community-based conservation interventions

    Directory of Open Access Journals (Sweden)

    Gretchen Walters

    2015-12-01

    Full Text Available Addressing today's environmental challenges is intimately linked to understanding and improving natural resource governance institutions. As a result conservation initiatives are increasingly realizing the importance of integrating local perspectives of land tenure arrangements, natural resource rights, and local beliefs into conservation approaches. However, current work has not sufficiently considered the dynamic nature of natural resource governance institutions over time and the potential implications for current conservation interventions. We therefore explored how and why hunting governance has changed since the precolonial period in two ethnic hunting communities in Gabon, Central Africa, integrating various ethnographic methods with resource-use mapping, and a historic literature review. In both communities, hunting governance has undergone significant changes since the precolonial period. A closed-access, lineage-based system of resource use with strict penalties for trespassing, has evolved into a more open-access system, in which the influence of customary governance systems, including magico-political aspects, has declined. These changes have occurred mainly in response to policies and governance structures put in place by the colonial government and postindependence, early state laws. This included a policy of merging villages, the introduction of more modern hunting techniques such as guns and wire cables, and a shift from community to government ownership of the land. Current governance structures are thus the product of a complex mixture of customary, colonial and state influences. These findings suggest that a historical perspective of resource governance, gained through in-depth and long-term engagement with local communities, can provide important insights for community-based conservation approaches, such as helping to identify potential causes and perceptions of environmental change and to design more suitable conservation

  10. Quantum game theory and open access publishing

    2007-08-01

    The digital revolution of the information age and in particular the sweeping changes of scientific communication brought about by computing and novel communication technology, potentiate global, high grade scientific information for free. The arXiv, for example, is the leading scientific communication platform, mainly for mathematics and physics, where everyone in the world has free access on. While in some scientific disciplines the open access way is successfully realized, other disciplines (e.g. humanities and social sciences) dwell on the traditional path, even though many scientists belonging to these communities approve the open access principle. In this paper we try to explain these different publication patterns by using a game theoretical approach. Based on the assumption, that the main goal of scientists is the maximization of their reputation, we model different possible game settings, namely a zero sum game, the prisoners’ dilemma case and a version of the stag hunt game, that show the dilemma of scientists belonging to “non-open access communities”. From an individual perspective, they have no incentive to deviate from the Nash equilibrium of traditional publishing. By extending the model using the quantum game theory approach it can be shown, that if the strength of entanglement exceeds a certain value, the scientists will overcome the dilemma and terminate to publish only traditionally in all three settings.

    Full Text Available Ramsay Hunt syndrome (RHS is characterized by facial paralysis, inner ear dysfunction, periauricular pain, and herpetiform vesicles. The reported incidence in children is 2.7/100,000. The pathogenesis involves the reactivation of latent varicella zoster virus (VZV in the geniculate ganglion of the facial nerve. The recovery rate is better in children than in adults. This paper discusses a 12-year-old girl with a rare case of peripheral facial paralysis caused by RHS and reviews the literature.

  19. Duality, Phase Structures and Dilemmas in Symmetric Quantum Games

    Ichikawa, T; Ichikawa, Tsubasa; Tsutsui, Izumi

    2006-01-01

    Symmetric quantum games for 2-player, 2-qubit strategies are analyzed in detail by using a scheme in which all pure states in the 2-qubit Hilbert space are utilized for strategies. We consider two different types of symmetric games exemplified by the familiar games, the Battle of the Sexes (BoS) and the Prisoners' Dilemma (PD). These two types of symmetric games are shown to be related by a duality map, which ensures that they share common phase structures with respect to the equilibria of the strategies. We find eight distinct phase structures possible for the symmetric games, which are determined by the classical payoff matrices from which the quantum games are defined. We also discuss the possibility of resolving the dilemmas in the classical BoS, PD and the Stag Hunt (SH) game based on the phase structures obtained in the quantum games. It is observed that quantization cannot resolve the dilemma fully for the BoS, while it generically can for the PD and SH if appropriate correlations for the strategies of...

  7. Cat dilemma: too protected to escape trophy hunting?

    Directory of Open Access Journals (Sweden)

    Lucille Palazy

    Full Text Available Trophy hunting is one of the most controversial issues in the field of biodiversity conservation. In particular, proponents and opponents debate fiercely over whether it poses a threat to hunted populations. Here, we show that trophy hunting constitutes a greater menace to threatened species than previously realized. Because humans value rarity, targeted species that are threatened are likely to be disproportionately hunted, thereby becoming even more vulnerable, which could eventually push them to extinction. With the ten felid species currently hunted for their trophies, we present evidence that (1 the number of killed individuals increases with time, in several cases exponentially, despite population declines, (2 the price of trophies is strongly dependent on species protection status, (3 changes of protection status coincide with counter-intuitive changes of hunting pressures: protection intensification with augmented hunting effort, and protection relaxation with lower effort. This suggests an over-exploitation of trophy-hunted felids and the necessity of a better quota system coupled with reconsidered protection methods.

    Objectives: The repetitive and sometimes mundane nature of conventional rehabilitation therapy provides an ideal opportunity for development of interactive and challenging therapeutic games that have the potential to engage and motivate the players. Certain game design parameters that may encourage patients to actively participate by making the games more enjoyable have been identified. In this article, we describe a formative study in which we designed and evaluated some of these parameters with healthy subjects. Materials and Methods: The "operant conditioning" and "scoring" design parameters were incorporated in a remake of a classic labyrinth game, "Marble Maze." A group of participants (n=37) played the game twice: Once in the control condition without both modalities and then with either one of the parameters or with both. Measures of game duration and number of fails in the game were recorded along with survey questionnaires to measure player perceptions of intrinsic motivation on the game. Results: Longer playtimes, higher levels of interest/enjoyment, and effort to play the game were recorded with the introduction of these parameters. Conclusions: This study provides an understanding on how game design parameters can be used to motivate and encourage people to play longer. With these positive results, future aims are to test the parameters with stroke patients, providing much clearer insight as to what influences these parameters have on patients undergoing therapy. The ultimate goal is to utilize game design in order to maintain longer therapeutic interaction between a patient and his or her therapy medium.

    Wildlife subsistence hunting is a major source of protein for tropical rural populations and a prominent conservation issue. The intrinsic rate of natural increase. (rmax ) of populations is a key reproductive parameter in the most used assessments of hunting sustainability. However, researchers face severe difficulties in obtaining reproductive data in the wild, so these assessments often rely on classic reproductive rates calculated mostly from studies of captive animals conducted 30 years ago. The result is a flaw in almost 50% of studies, which hampers management decision making. We conducted a 15-year study in the Amazon in which we used reproductive data from the genitalia of 950 hunted female mammals. Genitalia were collected by local hunters. We examined tissue from these samples to estimate birthrates for wild populations of the 10 most hunted mammals. We compared our estimates with classic measures and considered the utility of the use of rmax in sustainability assessments. For woolly monkey (Lagothrix poeppigii) and tapir (Tapirus terrestris), wild birthrates were similar to those from captive populations, whereas birthrates for other ungulates and lowland-paca (Cuniculus paca) were significantly lower than previous estimates. Conversely, for capuchin monkeys (Sapajus macrocephalus), agoutis (Dasyprocta sp.), and coatis (Nasua nasua), our calculated reproductive rates greatly exceeded often-used values. Researchers could keep applying classic measures compatible with our estimates, but for other species previous estimates of rmax may not be appropriate. We suggest that data from local studies be used to set hunting quotas. Our maximum rates of population growth in the wild correlated with body weight, which suggests that our method is consistent and reliable. Integration of this method into community-based wildlife management and the training of local hunters to record pregnancies in hunted animals could efficiently generate useful information of life

    Background Lead-free hunting bullets are an alternative to lead-containing bullets which cause health risks for humans and endangered scavenging raptors through lead ingestion. However, doubts concerning the effectiveness of lead-free hunting bullets hinder the wide-spread acceptance in the hunting and wildlife management community. Methods We performed terminal ballistic experiments under standardized conditions with ballistic soap as surrogate for game animal tissue to characterize dimensionally stable, partially fragmenting, and deforming lead-free bullets and one commonly used lead-containing bullet. The permanent cavities created in soap blocks are used as a measure for the potential wound damage. The soap blocks were imaged using computed tomography to assess the volume and shape of the cavity and the number of fragments. Shots were performed at different impact speeds, covering a realistic shooting range. Using 3D image segmentation, cavity volume, metal fragment count, deflection angle, and depth of maximum damage were determined. Shots were repeated to investigate the reproducibility of ballistic soap experiments. Results All bullets showed an increasing cavity volume with increasing deposited energy. The dimensionally stable and fragmenting lead-free bullets achieved a constant conversion ratio while the deforming copper and lead-containing bullets showed a ratio, which increases linearly with the total deposited energy. The lead-containing bullet created hundreds of fragments and significantly more fragments than the lead-free bullets. The deflection angle was significantly higher for the dimensionally stable bullet due to its tumbling behavior and was similarly low for the other bullets. The deforming bullets achieved higher reproducibility than the fragmenting and dimensionally stable bullets. Conclusion The deforming lead-free bullet closely resembled the deforming lead-containing bullet in terms of energy conversion, deflection angle, cavity shape

    Protected areas are essential for conservation of wildlife populations. However, in the tropics there are two important factors that may interact to threaten this objective: 1) road development associated with large-scale resource extraction near or within protected areas; and 2) historical occupancy by traditional or indigenous groups that depend on wildlife for their survival. To manage wildlife populations in the tropics, it is critical to understand the effects of roads on the spatial extent of hunting and how wildlife is used. A geographical analysis can help us answer questions such as: How do roads affect spatial extent of hunting? How does market vicinity relate to local consumption and trade of bushmeat? How does vicinity to markets influence choice of game? A geographical analysis also can help evaluate the consequences of increased accessibility in landscapes that function as source-sink systems. We applied spatial analyses to evaluate the effects of increased landscape and market accessibility by road development on spatial extent of harvested areas and wildlife use by indigenous hunters. Our study was conducted in Yasuní Biosphere Reserve, Ecuador, which is impacted by road development for oil extraction, and inhabited by the Waorani indigenous group. Hunting activities were self-reported for 12–14 months and each kill was georeferenced. Presence of roads was associated with a two-fold increase of the extraction area. Rates of bushmeat extraction and trade were higher closer to markets than further away. Hunters located closer to markets concentrated their effort on large-bodied species. Our results clearly demonstrate that placing roads within protected areas can seriously reduce their capacity to sustain wildlife populations and potentially threaten livelihoods of indigenous groups who depend on these resources for their survival. Our results critically inform current policy debates regarding resource extraction and road building near or within

  1. Identity-driven differences in stakeholder concerns about hunting wolves.

    Michelle L Lute

    Full Text Available Whereas past wolf management in the United States was restricted to recovery, managers must now contend with publicly contentious post-recovery issues including regulated hunting seasons. Understanding stakeholder concerns associated with hunting can inform stakeholder engagement, communication, and policy development and evaluation. Social identity theory (SIT has been used to understand how groups interact, why they conflict, and how collaboration may be achieved. Applying SIT to stakeholder conflicts about wolf hunting may help delineate groups according to their concern about, support for or opposition to the policy choice of hunting wolves. Our objective was to assess concerns about hunting as a tool to resolve conflict in Michigan, using SIT as a framework. We used a mixed-modal sampling approach (e.g., paper, Internet with wolf hunting-related public meeting participants in March 2013. Survey questions focused on 12 concerns previously identified as associated with hunting as a management tool to resolve conflict. Respondents (n  =  666 cared greatly about wolves but were divided over hunting wolves. Wolf conflicts, use of science in policy decisions, and maintaining a wolf population were the highest ranked concerns. Principle components analysis reduced concerns into three factors that explained 50.7% of total variance; concerns crystallized over justifications for hunting. General linear models revealed a lack of geographic influence on care, fear and support for hunting related to wolves. These findings challenge assumptions about regional differences and suggest a strong role for social identity in driving dichotomized public perceptions in wildlife management.

  2. Autocratic strategies for alternating games.

    Science.gov (United States)

    McAvoy, Alex; Hauert, Christoph

    2017-02-01

    Repeated games have a long tradition in the behavioral sciences and evolutionary biology. Recently, strategies were discovered that permit an unprecedented level of control over repeated interactions by enabling a player to unilaterally enforce linear constraints on payoffs. Here, we extend this theory of "zero-determinant" (or, more generally, "autocratic") strategies to alternating games, which are often biologically more relevant than traditional synchronous games. Alternating games naturally result in asymmetries between players because the first move matters or because players might not move with equal probabilities. In a strictly-alternating game with two players, X and Y, we give conditions for the existence of autocratic strategies for player X when (i) X moves first and (ii) Y moves first. Furthermore, we show that autocratic strategies exist even for (iii) games with randomly-alternating moves. Particularly important categories of autocratic strategies are extortionate and generous strategies, which enforce unfavorable and favorable outcomes for the opponent, respectively. We illustrate these strategies using the continuous Donation Game, in which a player pays a cost to provide a benefit to the opponent according to a continuous cooperative investment level. Asymmetries due to alternating moves could easily arise from dominance hierarchies, and we show that they can endow subordinate players with more autocratic strategies than dominant players.

    General game players are computer systems able to play strategy games based solely on formal game descriptions supplied at ""runtime"" (n other words, they don't know the rules until the game starts). Unlike specialized game players, such as Deep Blue, general game players cannot rely on algorithms designed in advance for specific games; they must discover such algorithms themselves. General game playing expertise depends on intelligence on the part of the game player and not just intelligence of the programmer of the game player.GGP is an interesting application in its own right.

    Eukaryotic cells package their DNA with histone proteins to form chromatin that can be regulated to enable transcription, DNA repair and replication in response to cellular needs and external stimuli. A wealth of recent studies of post-translational histone modifications and histone variants have led to an explosion of insights into and more questions about how these processes might be regulated. Work from Donald Hunt and colleagues contributed greatly to our understanding of the "histone code" by developing novel methods to study and identify histone modifications in both generic and specialized variant histone proteins. Without his expertise, the field of chromatin biology would not be where it is today. In recognition, we are pleased to contribute to a special issue of the International Journal of Mass Spectrometry dedicated to the many advances pioneered by the Hunt laboratory, which have enhanced the science of many fields and the careers of many scientists.

    Full Text Available Tabletop role-playing games combine performance, procedures, and improvisation to both tell stories and reflect on the nature of storytelling. This article discusses the three games 1,001 Nights by Meguey Baker, What Is a Role-Playing Game? by Epidiah Ravachol, and World Wide Wrestling by Nathan D. Paoletta in terms of how their procedures of play and framing devices comment on the tabletop role-playing game medium. Taken together, these three games on games demonstrate the inherent tensions of player motivation, collective fiction creation, and selling a performance to one’s fellow players, and how RPG theory helps us to understand them.

  9. Non-Digital Game Playing by Older Adults.

    2017-09-01

    Research on video games' effect on cognition and behaviour has been extensive, yet little research has explored non-digital forms of game playing, especially among older adults. As part of a larger survey on game playing, 886 respondents (≥ age 55) filled out questionnaires about non-digital game play. The study aims were to determine perceived benefits of non-digital game play and to determine socio-demographic factors that might predict perceived benefits. Survey results indicate that non-digital game playing is social in nature and common (73% of respondents) among older adults. Older adults play for fun, but also to help maintain their cognition. Regression analyses indicated various socio-demographic factors - age, education, gender, and race - were independently associated with perceived benefits from game playing. The results thus emphasize the importance of non-digital game playing in this population and suggest that efforts to facilitate game playing may improve social interactions and quality of life.

    Full Text Available Ramsay-Hunt Syndrome (RHS is a rare disease characterized by peripheral facial paralysis, cochleovestibular symptoms, skin lesions in the auricular canal and/or in the auricula and rarely skin lesions in the hard palate. The disease is also known as Herpes zoster oticus or herpes zoster cephalicus. Early diagnosis and antiviral treatment of peripheral nerve paralysis associated with higher rates of improvement. RHS, which is a rare disease in children should be considered in the differential diagnosis in children presenting with peripheral nerve palsy, erythema, vesicular lesions and/or ear pain. Here we presented a child case in which the first symptom was ear pain and facial palsy, followed by vesicular lesions in the ear pinna, and in the external auditory meatus.The patient recovered without squela of oral steroids and antiviral therapy.

  14. Hunting for the Quantum Cheshire Cat

    2012-01-01

    The proposal of Aharonov, Popescu, and Skrzypczyk [arXiv:1202.0631] of disembodying physical properties from particles is analyzed. It is argued that: (1) in order to state that the cat is at one location and the smile at another, one should look at correlations, not mean values; (2) a weak value of one for the presence of the cat describes the average over a large number of trials, where the detector gives in each trial outputs that are not zero nor one, and that are much larger than unity (they can be large and negative as well); (3) once these issues are addressed, the specific model proposed does not provide evidence for disembodiment of physical properties. Here, the exact probability distribution and its characteristic function are derived for arbitrary coupling strength, preparation and post-selection. This allows to successfully hunt down the quantum Cheshire cat.

  15. Bump-hunting in LHC ttbar events

    2016-01-01

    We demonstrate that a purposefully normalised NNLO top pair invariant mass differential spectrum can have very small theoretical uncertainty and, in particular, a small sensitivity to the top quark mass. Such observable can thus be a very effective bump-hunting tool for resonances decaying to top pair events during LHC Run II and beyond. To illustrate how the approach works, we concentrate on one specific example of current interest, namely, the possible 750 GeV di-gamma excess resonance Phi. Considering only theoretical uncertainties, we demonstrate that it is possible to distinguish pp -> Phi -> tt signals studied in the recent literature [Hespel, Maltoni and Vryonidou, arXiv:1606.04149] from the pure SM background with very high significance. Alternatively, in case of non-observation, a strong upper limit on the decay rate Phi -> tt can be placed.

  18. Bear-baiting may exacerbate wolf-hunting dog conflict.

    2013-01-01

    The influence of policy on the incidence of human-wildlife conflict can be complex and not entirely anticipated. Policies for managing bear hunter success and depredation on hunting dogs by wolves represent an important case because with increasing wolves, depredations are expected to increase. This case is challenging because compensation for wolf depredation on hunting dogs as compared to livestock is less common and more likely to be opposed. Therefore, actions that minimize the likelihood of such conflicts are a conservation need. We used data from two US states with similar wolf populations but markedly different wolf/hunting dog depredation patterns to examine the influence of bear hunting regulations, bear hunter to wolf ratios, hunter method, and hunter effort on wolf depredation trends. Results indicated that the ratio of bear hunting permits sold per wolf, and hunter method are important factors affecting wolf depredation trends in the Upper Great Lakes region, but strong differences exist between Michigan and Wisconsin related in part to the timing and duration of bear-baiting (i.e., free feeding). The probability that a wolf depredated a bear-hunting dog increases with the duration of bear-baiting, resulting in a relative risk of depredation 2.12-7.22× greater in Wisconsin than Michigan. The net effect of compensation for hunting dog depredation in Wisconsin may also contribute to the difference between states. These results identified a potential tradeoff between bear hunting success and wolf/bear-hunting dog conflict. These results indicate that management options to minimize conflict exist, such as adjusting baiting regulations. If reducing depredations is an important goal, this analysis indicates that actions aside from (or in addition to) reducing wolf abundance might achieve that goal. This study also stresses the need to better understand the relationship among baiting practices, the effect of compensation on hunter behavior, and depredation

    The most common presentation of herpes zoster in the head and neck region is called Ramsay Hunt syndrome (RHS), which rarely accompanies multiple cranial neuropathy. Herpes zoster also involves the mucous membrane of the tongue, palate, pharynx, and larynx. Herpes zoster infection of the larynx accompanied by Ramsay Hunt syndrome with cranial polyneuropathy is extremely rare, with only few reported cases in the literature. At the time of this report, a review of the medical literature disclosed 4 reported cases of herpes zoster laryngitis accompanied by Ramsay Hunt syndrome. Herein, we present 2 additional cases and report the clinical outcome of cranial polyneuropathy with a review of the literature.

    Full Text Available Ramsay hunt syndrome is not just a syndrome but it's rather an infectious disease caused by reactivation of latent varicella-zoster virus in geniculate ganglion. This was first explained by J. Ramsay Hunt as a triad of complications like otalgia, mucosal and cutaneous rashes with or without trigeminal facial palsy. The facial palsy can occur with characteristic vesicles along the path of nerve. We present a case of Ramsay Hunt syndrome in a 48-year-old male. The unilateral pattern of facial involvement and presence of vesicles assisted us for early diagnosis, distinguishing the syndrome with diseases mimicking other severe neurological illnesses and prompt treatment.

    2013-01-01

    According to educational gaming advocates, the engaging nature of games encourages sustained game play and enhanced attention to learning outcomes among players. Because children's and adolescents' play time varies by game genre, engagement with a game likely reflects the match between the genre and the player's preferences and needs. Youth learn which games are likely to promote satisfying psychological needs and yield positive experiences, which then informs their engagement with the games. A model is presented for research and development of educational games based on uses and gratifications theory from communication science, as well as developmental science and cognitive science findings.

    New kinds of knowledge, usage patterns and management strategies of natural resources emerge in local communities as a way of coping with uncertainty in a changing world. Studying how human groups adapt and create new livelihoods strategies are important research topics for creating policies in natural resources management. Here, we study the adoption and development of lagartos (Crocodylus moreletii) commercial hunting by Mayan people from a communal land in Quintana Roo state. Two questions guided our work: how did the Mayan learn to hunt lagartos? And how, and in what context, did knowledge and management practices emerge? We believe that social structures, knowledge and preexisting skills facilitate the hunting learning process, but lagarto ecological knowledge and organizational practice were developed in a "learning by doing" process. We conducted free, semi-structured and in-depth interviews over 17 prestigious lagartos hunters who reconstructed the activity through oral history. Then, we analyzed the sources of information and routes of learning and investigated the role of previous knowledge and social organization in the development of this novel activity. Finally, we discussed the emergence of hunting in relation to the characteristic of natural resource and the tenure system. Lagarto hunting for skin selling was a short-term activity, which represented an alternative source of money for some Mayans known as lagarteros. They acquired different types of knowledge and skills through various sources of experience (individual practice, or from foreign hunters and other Mayan hunters). The developed management system involved a set of local knowledge about lagartos ecology and a social organization structure that was then articulated in the formation of "working groups" with particular hunting locations (rumbos and trabajaderos), rotation strategies and collaboration among them. Access rules and regulations identified were in an incipient state of development

  13. Local Strategy Improvement for Parity Game Solving

    Directory of Open Access Journals (Sweden)

    Oliver Friedmann

    2010-06-01

    Full Text Available The problem of solving a parity game is at the core of many problems in model checking, satisfiability checking and program synthesis. Some of the best algorithms for solving parity game are strategy improvement algorithms. These are global in nature since they require the entire parity game to be present at the beginning. This is a distinct disadvantage because in many applications one only needs to know which winning region a particular node belongs to, and a witnessing winning strategy may cover only a fractional part of the entire game graph. We present a local strategy improvement algorithm which explores the game graph on-the-fly whilst performing the improvement steps. We also compare it empirically with existing global strategy improvement algorithms and the currently only other local algorithm for solving parity games. It turns out that local strategy improvement can outperform these others by several orders of magnitude.

  20. Emotionally Colorful Reflexive Games

    CERN Document Server

    Tarasenko, Sergey

    2011-01-01

    This study addresses the matter of reflexive control of the emotional states by means of Reflexive Game Theory (RGT). It is shown how to build a bridge between RGT and emotions. For this purpose the Pleasure-Arousal-Dominance (PAD) model is adopted. The major advantages of RGT are its ability to predict human behavior and unfold the entire spectra of reflexion in the human mind. On the other hand, PAD provides ultimate approach to model emotions. It is illustrated that emotions are reflexive processes and, consequently, RGT fused with PAD model is natural solution to model emotional interactions between people. The fusion of RGT and PAD, called Emotional Reflexive Games (ERG), inherits the key features of both components. Using ERG, we show how reflexive control can be successfully applied to model human emotional states. Up to date, EGR is a unique methodology capable of modeling human reflexive processes and emotional aspects simultaneously.
