A INOVAÇÃO, A COOPERAÇÃO E O APRENDIZADO NO ARRANJO PRODUTIVO LOCAL DO AGRONEGÓCIO LEITE NO MUNICÍPIO DE JARU AgEcon
Riva, Fabiana Rodrigues; Costa, Patricia Ferreira; Cordeiro, Higor.
As informações se restringem cada vez mais em poder de menos pessoas ocasionando uma disparidade na utilização das praticas administrativas. O setor agrícola constantemente tem sofrido com esta situação, pois os micros e pequenos empresários dificilmente conseguem acompanhar tais mudanças e o nível de competitividade destes diminui ocasionando baixa produtividade e perdas na qualidade dos produtos, prejudicando os processos de aprendizagem, cooperação e inovação e consequentemente o desenvolvimento deste APL. Buscando identificar como ocorrem esses processos e conhecer sua importância para os atores de um arranjo foi realizado um levantamento de suas interações nos diversos segmentos do arranjo produtivo local do agronegócio leite no município de Jaru em...

A link between the hippocampal and the striatal memory systems of the brain Anais da ABC (AABC)
Rossato,Janine I.; Zinn,Carolina G.; Furini,Cristiane; Bevilaqua,Lia R.M.; Medina,Jorge H.; Cammarota,Martín; Izquierdo,Iván.
Two major memory systems have been recognized over the years (Squire 1987): the declarative memory system, which is under the control of the hippocampus and related temporal lobe structures, and the procedural or habit memory system, which is under the control of the striatum and its connections. Most if not all learning tasks studied in animals, however, involve either the performance or the suppression of movement; this, if learned well, may be viewed as having become a habit. It is agreed that memory rules change from their first association to those that take place when the task is mastered. Does this change of rules involve a switch from one memory system to another? Here we will comment on: 1) reversal learning in the Morris water maze (MWM), in...

Adaptation or Manipulation? Unpacking Climate Change Response Strategies Ecology and Society
Thomsen, Dana C; Sustainability Research Centre, University of the Sunshine Coast; dthomsen@usc.edu.au; Smith, Timothy F; Sustainability Research Centre, University of the Sunshine Coast; tim.smith@usc.edu.au; Keys, Noni; Sustainability Research Centre, University of the Sunshine Coast; nkeys@usc.edu.au.
Adaptation is a key feature of sustainable social–ecological systems. As societies traverse various temporal and spatial scales, they are exposed to differing contexts and precursors for adaptation. A cursory view of the response to these differing contexts and precursors suggests the particular ability of persistent societies to adapt to changing circumstances. Yet a closer examination into the meaning of adaptation and its relationship to concepts of resilience, vulnerability, and sustainability illustrates that, in many cases, societies actually manipulate their social–ecological contexts rather than adapt to them. It could be argued that manipulative behaviors are a subset of a broader suite of adaptive behaviors; however, this...

Adaptive Comanagement in the Venice Lagoon? An Analysis of Current Water and Environmental Management Practices and Prospects for Change Ecology and Society
Munaretto, Stefania; University IUAV of Venice, Faculty of Urban and Regional Planning, Venice, Italy; VU University - Institute for Environmental Studies (IVM), Amsterdam, Netherlands; stefania.munaretto@ivm.vu.nl; Huitema, Dave; VU University - Institute for Environmental Studies (IVM), Amsterdam, Netherlands; dave.huitema@ivm.vu.nl.
Adaptive comanagement (ACM) is often suggested as a way of handling the modern challenges of environmental governance, which include uncertainty and complexity. ACM is a novel combination of the learning dimension of adaptive management and the linkage dimension of comanagement. As has been suggested, there is a need for more insight on enabling policy environments for ACM success and failure. Picking up on this agenda we provide a case study of the world famous Venice lagoon in Italy. We address the following questions: first, to what extent are four institutional prescriptions typically associated with ACM currently practiced in the Venice system? Second, to what extent is learning taking place in the Venice system? Third, how is learning related to the...

Are There Scientific Criteria for Putting Short-term Conservation Ahead of Learning? No. Ecology and Society
Hinrichsen, Richard A; Hinrichsen Environmental Services; hinrich@seanet.com.
Kai Lee asks "Are there clearly articulated scientific criteria for putting short-term conservation ahead of learning? (That is, are there conservation situations where we know enough not to need to worry about surprises?)" There can be no such scientific criteria, even in the most trivial of circumstances, because it is really a question of societal values. In cases in which societal values favor conservation of an endangered or threatened population, reliable learning is unlikely to be placed ahead of short-term conservation, partly because it is uncertain whether learning will really improve the prospects for population recovery. Given the prevailing societal values and scientific realities surrounding endangered or threatened populations, the question...

Are We Entering an Era of Concatenated Global Crises? Ecology and Society
Biggs, Duan; ARC Centre of Excellence for Coral Reef Studies, James Cook University, Townsville Australia; ancientantwren@gmail.com; Biggs, Reinette (Oonsie); Stockholm Resilience Centre, Stockholm University, Sweden; oonsie.biggs@stockholmresilience.su.se; Dakos, Vasilis; Department of Aquatic Ecology & Water Quality Management, Wageningen University; vasileios.dakos@wur.nl; Scholes, Robert J; CSIR Natural Resources and the Environment, Pretoria, South Africa; BScholes@csir.co.za; Schoon, Michael; School of Human Evolution and Social Change, Arizona State University; Michael.Schoon@asu.edu.
An increase in the frequency and intensity of environmental crises associated with accelerating human-induced global change is of substantial concern to policy makers. The potential impacts, especially on the poor, are exacerbated in an increasingly connected world that enables the emergence of crises that are coupled in time and space. We discuss two factors that can interact to contribute to such an increased concatenation of crises: (1) the increasing strength of global vs. local drivers of change, so that changes become increasingly synchronized; and (2) unprecedented potential for the propagation of crises, and an enhanced risk of management interventions in one region becoming drivers elsewhere, because of increased connectivity. We discuss the...

Caractérisation de l’adaptation comportementale des téléostéens en élevage : plasticité et effets de la domestication ArchiMer
Benhaim, David.
The farming of aquatic animals has started recently in comparison with that of terrestrial species which domestication started 10 500 years ago. Aquaculture is however the fastest growing animal food-production sector. This sector has now to face several challenges threatening its sustainability. Indeed, aquaculture future largely depends upon the reduction of the reliance on feeds based ingredients derived from wild fishery resources, upon a better knowledge of fish domestication process and of the adaptation mechanisms and related welfare potential. The present work aims at a better understanding of the adaptation to farming conditions through a behavioural approach based on the comparison between wild vs. domesticated populations of three species: a...

Chlorpheniramine impairs spatial choice learning in telencephalon-ablated fish Biol. Res.
ROMAGUERA,FERNANDA; MATTIOLI,ROSANA.
This work investigated the effect of the Hj receptor blockade in the forebrain of ablated Carassius auratus in a simple stimulus-response learning task using a T-maze test with positive reinforcement. The goldfish were submitted to surgery for removal of both telencephalic lobes five days before beginning the experiment. A T-shaped glass aquarium was employed, with two feeders located at the extremities of the long arm. One of the two feeders was blocked. The experimental triáis were performed in nine consecutive days. Each fish was individually placed in the short arm and confined there for thirty seconds, then it was allowed to swim through the aquarium to search for food for ten minutes (máximum period). Time to find food was analysed in seconds....

Consequences of gestational diabetes to the brain and behavior of the offspring Anais da ABC (AABC)
SOUSA,RICARDO A.L. DE; TORRES,YASMIN S.; FIGUEIREDO,CLAUDIA P.; PASSOS,GISELLE F.; CLARKE,JULIA R..
ABSTRACT Gestational diabetes mellitus (GD) is a form of insulin resistance triggered during the second/third trimesters of pregnancy in previously normoglycemic women. It is currently estimated that 10% of all pregnancies in the United States show this condition. For many years, the transient nature of GD has led researchers and physicians to assume that long-term consequences were absent. However, GD diagnosis leads to a six-fold increase in the risk of developing type 2 diabetes (T2D) in women and incidence of obesity and T2D is also higher among their infants. Recent and concerning evidences point to detrimental effects of GD on the behavior and cognition of the offspring, which often persist until adolescence or adulthood. Considering that the...

CONTRIBUCIÓN DEL CAPITAL SOCIAL EN LA MICROEMPRESA RURAL AgEcon
Ojeda Lopez, Ruth Noemi; Mul Encalada, Jennifer; Lopez Canto, Leonor Elena; Jimenez Diez, Olivia.
The present study research identified the level of social capital in a small enterprise and its impact in the company itself. In Latin America, the importance of this concept lies in its relevance because diverse disciplines uses it as a reference setting, today it is used not only as part of political science and sociology, but also as part of the organization theory, economics, human behavior and management. It put emphasis in the relationships among people, among organizations and not in the individuals as isolated subjects. One of its advantages is that the social capital can contribute in the analysis of the small local communities from a social perspective and economical development. Because of the nature of the data handled in this study a...

Development of profitable milk production systems for northern Australia: an analysis of intensification of current systems AgEcon
Callow, Mark N.; Gobius, N.; Hetherington, G..
Milk producers in northern Australia are attempting to make rapid adjustments to production systems that enable them to compete in a newly deregulated market, although there is uncertainty about how to do this. Through industry consultation and expert review a process was developed to identify production systems that may be capable of supporting economic targets of 10% return on assets and 600,000 L milk/labour unit. A broadly based project team in terms of disciplines then used this process to identify five production systems which were each applicable to substantial numbers of current milk producers. These were modelled using whole farm economic analyses and annual feed planning, using an iterative process over an extended period, to determine the...

Disadoption of Agricultural Practices by Livestock Farmers AgEcon
Gedikoglu, Haluk; McCann, Laura M.J..
To be effective, policies that encourage farmers to use new technologies or practices need farmers both adopt and also keep using these technologies and practices. Adoption of new technologies has been widely analyzed in the literature. However, there is little known about the factors that cause farmers to keep using new technologies or quit using them. Using hazard function estimation, the current study investigates disadoption of Roundup Ready soybeans, injecting manure into the soil, and soil testing. The results of the current study show that over time farmers observe the true benefits and costs of these practices and they become more likely to disadopt these practices.

Dynamic Informative Advertising of New Experience Goods AgEcon
Saak, Alexander E..
This paper analyzes the optimal advertising and price policies of a monopolist who sells a new experience good over time to a population of heterogeneous forward-looking buyers. We consider informative advertising that can complement or substitute for learning-by-purchasing, and show that the advertising intensity always peaks during the early stages when the price extracts surplus from the buyers who are yet to learn their valuation for the good. We also show that even though informative advertising may temporarily raise prices and slow down the learning process, an advertising ban can reduce welfare.

Similar to research on social learning among adult participants in natural resources management, current research in the field of education claims that learning is situated in real-world practice, and occurs through recursive interactions between individual learners and their social and biophysical environment. In this article, we present an overview of the social and situated learning literatures from the fields of natural resources and education, and suggest ways in which educational programs for secondary and university students might be embedded in and contribute to efforts to enhance resilience of social–ecological systems at the local scale. We also describe three initiatives in which learning is situated in adaptive co-management and civic...

Effects of caffeine on learning and memory in rats tested in the Morris water maze BJMBR
Angelucci,M.E.M.; Cesário,C.; Hiroi,R.H.; Rosalen,P.L.; Cunha,C. Da.
We studied some of the characteristics of the improving effect of the non-specific adenosine receptor antagonist, caffeine, using an animal model of learning and memory. Groups of 12 adult male Wistar rats receiving caffeine (0.3-30 mg/kg, ip, in 0.1 ml/100 g body weight) administered 30 min before training, immediately after training, or 30 min before the test session were tested in the spatial version of the Morris water maze task. Post-training administration of caffeine improved memory retention at the doses of 0.3-10 mg/kg (the rats swam up to 600 cm less to find the platform in the test session, P<=0.05) but not at the dose of 30 mg/kg. Pre-test caffeine administration also caused a small increase in memory retrieval (the escape path of the rats...
