| The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country. The model is applied to bananas in Uganda, making use of disaggregated data on variety-specific farm-gate banana bunch prices and attributes. The hedonic analysis is applied at the farm-gate, the first link in the market chain, while accounting for the semi-subsistence nature of banana producing households. Within the framework of the agricultural household, where consumption and production decisions are non-separable, prices reflect the implicit marginal valuation of both consumption and production attributes jointly. The paper is motivated by the need to quantify the value of... |

| Teve-se como objetivo neste artigo abordar elementos teóricos já estudados sobre o processo de decisão, bem como da Economia dos Custos de Transação e da Análise Sistêmica, de forma a propor uma estrutura analítica sistêmica, multinível e interdisciplinar, que possa ser usada para o estudo da tomada de decisão de investimentos em cadeias produtivas agronegociais. Da consolidação do referencial teórico, por meio de estrutura analítica, aplicada a um estudo de caso, no caso a cadeia produtiva do biodiesel, pode-se perceber que na medida em que a commodity soja vai avançando nos elos da cadeia, vai se tornando um produto de maior valor agregado, cujos ativos envolvidos para seu processamento e distribuição possuem alta especificidade, o que por sua vez vai... |

| We aimed to contribute to the field of natural resource management (NRM) by introducing an alternative systemic context-based framework for planning, research, and decision making, which we expressed practically in the development of a decision-making “tool” or method. This holistic framework was developed in the process of studying a specific catchment area, i.e., the Sand River Catchment, but we have proposed that it can be generalized to studying the complexities of other catchment areas. Using the lens of systemic resilience to think about dynamic and complex environments differently, we have reflected on the development of a systemic framework for understanding water and livelihood security under transformation in postapartheid... |

| The paper sets out the agenda for reviewing models of decision making in the context of farmers’ use of seasonal climate forecasting. Such forecasts have been framed in terms of shifts in cumulative distribution functions of yields or gross margins. Typically they have been applied to choices about crop variety, crop type, time of planting or level of fertiliser application. Fundamental questions are: how do farmers conceptualise and make use of the information contained in seasonal climate forecasts? Do our models of decision making represent well the way in which these decisions are made? |

| This study presents an agent-based simulation modeling in an emergency department. In a traditional approach, a supervisor (or a manager) allocates the resources (receptionist, nurses, doctors, etc.) to different sections based on personal experience or by using decision-support tools. In this study, each staff agent took part in the process of allocating resources based on their observation in their respective sections, which gave the system the advantage of utilizing all the available human resources during the workday by being allocated to a different section. In this simulation, unlike previous studies, all staff agents took part in the decision-making process to re-allocate the resources in the emergency department. The simulation modeled the behavior... |

| Climate change and its associated consequences pose an increasing risk to public lands in the western United States. High-level mandates currently require federal agencies to begin planning for adaptation, but the extent to which these mandates have resulted in policies being implemented that affect on the ground practices is unclear. To examine the status of adaptation efforts, we conducted an original survey and semistructured interviews with land managers from the four major federal land management agencies in the U.S. states of Colorado, Utah, and Wyoming. The survey was designed to examine current planning for adaptation on public lands and how it differs from prior planning, the major challenges facing land managers in this region, the major... |

| Ecological assessments and monitoring programs often rely on indicators to evaluate environmental conditions. Such indicators are frequently developed by scientists, expressed in technical language, and target aspects of the environment that scientists consider useful. Yet setting environmental policy priorities and making environmental decisions requires both effective communication of environmental information to decision makers and consideration of what members of the public value about ecosystems. However, the complexity of ecological issues, and the ways in which they are often communicated, make it difficult for these parties to fully engage such a dialogue. This paper describes our efforts to develop a process for translating the indicators of... |

| How "default options" should be used in health risk assessment divides the risk analysis profession. Some argue that these should be "hard": set by policy, generally biased to be "health protective" and requiring a substantial body of evidence to replace by decision-specific alternatives. Others argue that they should be science-based, identified by consensus of the professional community, replaced by whatever decision-specific information may be available to the analyst. This paper shows that both positions have validity, and that both are incomplete. Each kind of construct has a useful role to play, but in different kinds of decisions. Because the two are different, we suggest giving them different names, "default option" being assigned to the... |

| This paper describes the development of a learning package to support improved pasture quality on New Zealand deer farms. The first step has been to determine the specific requirements of deer farmers that will enable them to improve pasture quality decisions on-farm. Decision support software that interprets and demonstrates the impacts of pasture quality and animal physiology on the performance of young growing deer has also been developed. Key themes identified to aid pasture management decision-making included identifying the right pasture quality, management systems to maintain pasture quality and maximising the potential of livestock. This paper reports on the type of knowledge that deer farmers require in the learning package. |
