Endogenous Learning and Consensual Understanding in Multilateral Negotiations: Arguing and Bargaining in the WTO AgEcon
Wolfe, Robert.
People at home and trade negotiators in Geneva cannot bargain what they do not understand, and what they bargain must be based on consensual understanding among the relevant actors, whether or not they agree on what to do about it. Consensual understanding is endogenous, arising in an argumentative process of learning structured by constitutive principles of a regime. In a departure from both rationalist and constructivist approaches to negotiation analysis in political science, my goal in this paper is to try to advance analysis of these questions by exploring the contribution that deliberation or arguing makes to learning. My proposition is that something happens at the multilateral negotiation table in addition to bargaining, something that alters...

Enhancing Adaptive Capacity in Food Systems: Learning at Farmers' Markets in Sweden Ecology and Society
Milestad, Rebecka; Department of Urban and Rural Studies, Swedish University of Agricultural Sciences; Division of Environmental Strategies Research, Royal Institute of Technology; rebecka.milestad@sol.slu.se; Westberg, Lotten; Department of Urban and Rural Studies, Swedish University of Agricultural Sciences;; Geber, Ulrika; County Administrative Board of Stockholm;.
This article examines how local food systems in the form of farmers' markets can enhance adaptive capacity and build social-ecological resilience. It does this by exploring the learning potential among farmers and customers. Learning can enable actors to adapt successfully and thus build adaptive capacity. Three forms of learning are investigated: instrumental, communicative, and emancipatory. These forms of learning constitute the foundation for lasting changes of behaviors. Local food systems are characterized by close links and opportunities for face-to-face interactions between consumers and producers of food, and are also institutions where farmers and customers can express and act upon their ethical values concerning food. However, local food systems...

Evaluation of effects of photooxidized Vespa orientalis venom on memory and learning in rats J. Venom. Anim. Toxins incl. Trop. Dis.
Mukund,H; Gawade,SP.
Wasp venom is mixture of complex proteins that have several physical and pharmacological properties. The photochemical detoxification of Vespa orientalis venom is expected to generate photooxidized venom sac extract (PVSE). Antigenically active PVSE is obtained by exposing the venom sac extract (VSE) of Vespa orientalis to ultraviolet radiation in the presence of methylene blue. The aim of the present work was to evaluate the effect of PVSE on learning and memory of rats. Detoxification of PVSE was evident since treated mice had longer survival time than the group of mice treated with VSE. Photooxidized VSE of V. orientalis revealed enhancement on learning and memory by shortening the time to reach food (TRF) in T-maze. In a 28-day study with rats, we...

Evaluation of self-feeders as a tool to study diet preferences in groups of Atlantic cod (Gadus morhua) ArchiMer
Millot, Sandie; Nilsson, Jonatan; Fosseidengen, Jan Erik; Begout, Marie-laure; Kristiansen, Tore.
Among other applications, self-feeding has been used to study food preferences in fish allowing them to choose between feeders with different food content. Preference tests assume that (i) trigger actuations are motivated by appetite, (ii) fish can learn which feeder contains which food and discriminate between feeders solely on the basis of their content, and (iii) in groups of fish, the triggering preferences is representative for the individuals of the group. We studied individual triggering behaviour in four groups of 14 Atlantic cod (length of 34 +/- 2 cm, weight of 424 +/- 102 g, mean +/- SE, water temperature comprised between 7-8 degrees C) that were first given the choice between two self-feeders with identical content (Period 1 of 14 days) and...

Extrapolation in Games of Coordination and Dominance Solvable Games AgEcon
Mengel, Friederike; Sciubba, Emanuela.
We study extrapolation between games in a laboratory experiment. Participants in our experiment first play either the dominance solvable guessing game or a Coordination version of the guessing game for five rounds. Afterwards they play a 3x3 normal form game for ten rounds with random matching which is either a game solvable through iterated elimination of dominated strategies (IEDS), a pure Coordination game or a Coordination game with pareto ranked equilibria. We find strong evidence that participants do extrapolate between games. Playing a strategically different game hurts compared to the control treatment where no guessing game is played before and in fact impedes convergence to Nash equilibrium in both the 3x3 IEDS and the Coordination games. Playing...

Frames of Scale Challenges in Finnish and Greek Biodiversity Conservation Ecology and Society
Apostolopoulou, Evangelia; Department of Ecology, School of Biology, Aristotle University of Thessaloniki ; evaposto@bio.auth.gr; Paloniemi, Riikka ; Environmental Policy Centre, Finnish Environment Institute (SYKE); riikka.paloniemi@ymparisto.fi.
Global conservation expansion has been associated with significant changes in cross-scale interactions and in the discourses surrounding them engendering new scale challenges in the field of biodiversity conservation. In this paper, we analyze frames of scale challenges by drawing on evidence from eight focus groups of stakeholders and scientists from Greece and Finland. By following a systematic frame analysis we found three dominant frames. First, framing scale challenges as mainly derived from knowledge gaps regarding ecological scale emphasizes the scale problems occurring when only limited consideration is given to the scale-dependence of ecological phenomena. This prioritizes the formulation of scientifically informed conservation policies,...

Generalization of temporal order detection skill learning: two experimental studies of children with dyslexia BJMBR
Murphy,C.F.B.; Schochat,E..
The objective of this study was to investigate the phenomenon of learning generalization of a specific skill of auditory temporal processing (temporal order detection) in children with dyslexia. The frequency order discrimination task was applied to children with dyslexia and its effect after training was analyzed in the same trained task and in a different task (duration order discrimination) involving the temporal order discrimination too. During study 1, one group of subjects with dyslexia (N = 12; mean age = 10.9 ± 1.4 years) was trained and compared to a group of untrained dyslexic children (N = 28; mean age = 10.4 ± 2.1 years). In study 2, the performance of a trained dyslexic group (N = 18; mean age = 10.1 ± 2.1 years) was compared at three...

Horizontal Evaluation: Stimulating social learning among peers AgEcon
Thiele, Graham; Devaux, Andre; Velasco, Claudio; Manrique, Kurt.
Horizontal evaluation is a flexible evaluation method that combines self-assessment and external review by peers. We have developed and applied this method for use within an Andean regional network that develops new methodologies for research and development (R&D). The involvement of peers neutralizes the lopsided power relations that prevail in traditional external evaluations, creating a more favourable atmosphere for learning and improvement. The central element of a horizontal evaluation is a workshop that brings together a group of ‘local participants’ who are developing a new R&D methodology and a group of ‘visitors’ or ‘peers’ who are also interested in the methodology. The workshop combines presentations about the methodology with field...

How Homophily Affects Learning and Diffusion in Networks AgEcon
Golub, Benjamin; Jackson, Matthew O..
We examine how three different communication processes operating through social networks are affected by homophily - the tendency of individuals to associate with others similar to themselves. Homophily has no effect if messages are broadcast or sent via shortest paths; only connection density matters. In contrast, homophily substantially slows learning based on repeated averaging of neighbors' information and Markovian diffusion processes such as the Google random surfer model. Indeed, the latter processes are strongly affected by homophily but completely independent of connection density, provided this density exceeds a low threshold. We obtain these results by establishing new results on the spectra of large random graphs and relating the spectra to...

Human Resources Management, Knowledge Sharing and Organizational Learning AgEcon
Baldini, Krista Kamborian.
This Brief reports the results of a study that explored the role of human resources policies and practices in fostering knowledge sharing and organizational learning. The study examined six centres of the Consultative Group on International Agricultural Research (CGIAR) and six organizations that are considered to be leaders in the field of knowledge sharing and organizational learning. Five of these were public or non-governmental and the sixth was a private corporation. All the organizations studied (including the CGIAR centres) are promoting knowledge sharing and organizational learning to some extent, generally in the context of broader organizational change. Some have comprehensive, integrated approaches to organizational change, but most efforts tend...

Identification and analysis of vocal communication pathways in birds through inducible gene expression Anais da ABC (AABC)
Mello,Claudio V..
The immediate-early gene zenk is an activity-dependent gene highly induced in auditory processing or vocal motor control brain areas when birds engage in hearing or producing song, respectively. Studies of the expression of zenk in songbirds and other avian groups will be reviewed here briefly, with a focus on how this analysis has generated new insights on the brain pathways and mechanisms involved in perceptual and motor aspects of vocal communication and vocal learning.

Idle Chatter or Learning? Evidence from Rural Tanzania of Social Learning about Clinicians and the Health System AgEcon
Adelman, Sarah W.; Essam, Timothy M.; Leonard, Kenneth L..
We examine data from rural Arusha region in Tanzania in which households are asked to recall the illness episodes of randomly chosen other households in their village. We analyze the probability that a household would be able to recall another illness episode as a function of the characteristics of the illness, the location and type of health care chosen and the outcome experienced. Households are more likely to recall severe illnesses and illnesses for which good quality care is important, illnesses that resulted in visits to hospitals or when the patient was not cured. In addition, households are more likely to recall illnesses that resulted in a visit to a facility where the average tenure of clinicians is less than two years old. The results are...

Impact of a plant-based diet on behavioural and physiological traits in sea bass (Dicentrarchus labrax) ArchiMer
Benhaim, David; Begout, Marie-laure; Pean, Samuel; Manca, Michael; Prunet, Patrick; Chatain, Beatrice.
Replacing aquaculture feeds based on fisheries-derived resources with plant-based diets could be a relevant strategy to improve the sustainability of aquaculture. Recent studies on sea bass have shown that the total and early replacement of marine products by plant products would have a moderate effect on fish growth and body lipid content. Whether a plant-based diet impacts behavioural and physiological traits possibly linked to fish welfare, is not known, however. Here, we studied the effect of a totally plant-based diet introduced at an early stage of sea bass development on self-feeding behaviour, learning ability in a T-maze and stress biomarkers. We first compared learning processes in self-feeding conditions, between naive fish fed a plant-based...

IMPLICATION OF THE INFORMATIC KNOWLEDGE AgEcon
Sorea, Daniella.
The contemporary education process is necessary tied to information-technology and to Informatic. By using the Internet as source and as knowledge’s transmission modality one modifies the learning parameters. From the quantitative point of view, the Informatic increases the education process efficiency. From the qualitative point of view, the Informatic imposes a change of the education paradigm. The Informatic determines status modifications for the purveyor and for the beneficiary of the knowledge. The Informatic modifies the psychosocial characteristics of the knowledge process too. Using the Internet supposes the assumption of at least two levels reality. A more than one level reality representation agrees with the quantum mechanics and with relativity...

Innovation Histories: A method from learning from experience AgEcon
Douthwaite, Boru; Ashby, Jacqueline.
Preparing an ‘innovation history’ is a method for recording and reflecting on an innovation process. People who have been involved in the innovation jointly construct a detailed written account (sometimes referred to as a ‘learning history’) based on their recollections and on available documents. The process of preparing this history stimulates discussion, reflection and learning amongst stakeholders. Subsequent planning can build on the lessons learned, formulate a shared vision and act as a catalyst for change. Based on the initial detailed account of the innovation process, more concise informational products can be prepared that summarize the innovation process for wider dissemination of findings. These may include public awareness materials, policy...

Innovative behaviour in fish: Atlantic cod can learn to use an external tag to manipulate a self-feeder ArchiMer
Millot, Sandie; Nilsson, Jonatan; Fosseidengen, Jan Erik; Begout, Marie-laure; Ferno, Anders; Braithwaite, Victoria A.; Kristiansen, Tore S..
This study describes how three individual fish, Atlantic cod (Gadus morhua L.), developed a novel behaviour and learnt to use a dorsally attached external tag to activate a self-feeder. This behaviour was repeated up to several hundred times, and over time these fish fine-tuned the behaviour and made a series of goal-directed coordinated movements needed to attach the feeder’s pull string to the tag and stretch the string until the feeder was activated. These observations demonstrate a capacity in cod to develop a novel behaviour utilizing an attached tag as a tool to achieve a goal. This may be seen as one of the very few observed examples of innovation and tool use in fish.
