scholarly journals The landscape of fear conceptual framework: definition and review of current applications and misuses

Landscapes of Fear (LOF), the spatially explicit distribution of perceived predation risk as seen by a population, is increasingly cited in ecological literature and has become a frequently used “buzz-word”. With the increase in popularity, it became necessary to clarify the definition for the term, suggest boundaries and propose a common framework for its use. The LOF, as a progeny of the “ecology of fear” conceptual framework, defines fear as the strategic manifest of the cost-benefit analysis of food and safety tradeoffs. In addition to direct predation risk, the LOF is affected by individuals’ energetic-state, inter- and intra-specific competition and is constrained by the evolutionary history of each species. Herein, based on current applications of the LOF conceptual framework, I suggest the future research in this framework will be directed towards: (1) finding applied management uses as a trait defining a population’s habitat-use and habitat-suitability; (2) studying multi-dimensional distribution of risk-assessment through time and space; (3) studying variability between individuals within a population; and (4) measuring eco-neurological implications of risk as a feature of environmental heterogeneity.

As the market size of the video industry continues to grow by 3.6 times increased in the past five years, more and more companies adopt video marketing. Under this circumstance, it is meaningful and important to discuss the marketing issues in this industry. The objective of this study is to clarify the definition, problems and countermeasures of video marketing. Literature was obtained through data retrieval, and the data was aggregated and analyzed by induction. Findings show that the problems of video marketing cover the laws, suppliers, buyers, competitors, and content technical issues. And we suggest that the future research can try to verify the key points of STP analysis (segmentation, targeting, and positioning), marketing mix, as well as the cost-benefit analysis in video marketing.

<p>El estudio de la valoración de los servicios de los ecosistemas es un área de investigación reciente en España pero que ha cobrado un fuerte impulso durante las últimas décadas. El carácter multidimensional de estos servicios, la diversidad de beneficiarios y partes interesadas, y los diferentes enfoques valorativos existentes hacen que su valoración resulte compleja. En este trabajo se presenta el marco conceptual para la valoración de los servicios provistos por los ecosistemas y una descripción de las metodologías más utilizadas, aplicado a los agroecosistemas españoles. Para ello se ha realizado una búsqueda en la base de datos del <em>Institute for Scientific Information </em>(ISI), dando como resultado una muestra de 101 trabajos. La metodología utilizada para su análisis ha sido de tipo cualitativo. Los resultados obtenidos muestran como el grueso de los trabajos de valoración de ecoservicios provistos por agroecosistemas en España se ha publicado durante los últimos cinco años y que entre las metodologías económicas más utilizadas destacan el análisis coste-beneficio, la valoración contingente y los experimentos de elección.</p><p>The study of the valuation of ecosystem services is a recent area of research in Spain but has gained strong impulse during the last decades.

This article analyzes definitions and the role of hostile takeovers at the Russian and European markets for corporate control. It develops the methodology of assessing the efficiency of anti-takeover defenses adapted to the conditions of the Russian market. The paper uses the cost-benefit analysis, where the costs and benefits of the pre-bid and post-bid defenses are compared.

Many countries are investing in measures to improve surface water quality, but the investment programmes for so doing are increasingly becoming subject to cost-benefit analysis. Whilst the cost of control measures can usually be determined for individual improvement schemes, there are currently no established procedures for valuing the benefits attributable to improved surface water quality. The paper describes a methodology that has been derived that now makes this possible.

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.
