| The need to develop successful collaborative strategies is an enduring problem in sustainable resource management. Our goal is to evaluate the relationship between information networks and conflict in the context of collaborative groundwater management in the rapidly growing central highland region of Arizona. In this region, water-management conflicts have emerged because of stakeholders’ differing geographic perspectives and competing scientific claims. Using social network analyses, we explored the extent to which the Verde River Basin Partnership (VRBP), which was charged with developing and sharing scientific information, has contributed to collaboration in the region. To accomplish this, we examined the role that this stakeholder... |

| Reducing Emissions from Deforestation and Forest Degradation (REDD+) is a priority issue for forest and climate policy in Indonesia, and REDD+ policy-making activity has been characterized by considerable public consultation. Despite this engagement, discussions on REDD+ in Indonesia are reported to have remained top-down, a disconcerting pattern when adaptive governance and transformational change require cross-scale and cross-sectoral communication. Explicitly modeling the patterns of information exchange related to REDD+ can clarify these claims and help identify potential barriers to the transformational change needed to implement REDD+. We used data obtained through semistructured and structured interviews held in 2011 with representatives from a... |

| ABSTRACT At present, most large machinery and vehicle engines are electronically controlled but their electronic control systems are too expensive to be popularised and applied in small gasoline engines with relatively low prices. Therefore, small gasoline engines still use mechanical speed regulators. Mechanical speed regulators not only have the defects of inertia lag, friction resistance, inherent speed regulation and the like, but also have the disadvantage that dynamic performance and steady performance cannot be combined, which is not suitable for the increasingly improved speed regulation performance of gasoline engines. This paper describes the design of an electronically controlled intelligent governor for small gasoline engines. Starting from a... |

| Diesel fuel is used widely in Brazil and worldwide. On the other hand, the growing environmental awareness leads to a greater demand for renewable energy resources. Thus, this study aimed to evaluate the use of different blends of soybean (Glycine max) methyl biodiesel and diesel in an ignition compression engine with direct injection fuel. The tests were performed on an electric eddy current dynamometer, using the blends B10, B50 and B100, with 10; 50 e 100% of biodiesel, respectively, in comparison to the commercial diesel B5, with 5% of biodiesel added to the fossil diesel. The engine performance was analyzed trough the tractor power take off (PTO) for each fuel, and the best results obtained for the power and the specific fuel consumption,... |

| ABSTRACT The use of fuels for agricultural Diesel engines cycle, both of mineral origin (Diesel) or vegetable and animal origin (biodiesel) can significantly alter its performance. Therefore, the aim of this study was to quantify the change in torque, power and consumption of agricultural Diesel engine fuel using minerals and vegetables fuels. It was used a tractor power take-off coupled to a magnetic brake dynamometer (for measuring speed and torque for subsequent calculation of power), and a flow meter (for measuring the hourly fuel consumption and specific fuel consumption calculation). Eleven different fuels (S10 mineral diesel with 5%, 10%, 15%, 20% and 50% biodiesel and mineral diesel S500 with 5%, 10%, 15%, 20% and 50% biodiesel, have been used pure... |

| In marine spatial planning (MSP), the production of knowledge about marine-based activities is fundamental because it informs the process through which policies delineating the use of space are created and maintained. This paper revises our view of knowledge—developed during the mapping and planning processes—as the undisputed factual basis on which policy is developed. Rather, it argues that the construction, management, validation, and marginalisation of different types of knowledge stemming from different stakeholders or disciplinary approaches is at the heart of policy and planning processes. Using the case of fisheries-generated knowledge in the implementation of MSP, we contend that the fisheries data informing the MSP process are still very much... |

| Power plays a key role in any chain relationship. In the past large manufacturers such as Unilever and Nestle were the most dominant players in the chain. However, as a result of consolidation among retailers, power has shifted towards retailers. Nowadays such retailers as Wal-Mart, Carrefour, and Tesco are seen as powerful gatekeepers controlling the access to the end consumer. Moreover, branded manufacturers and large multinational retailers become increasingly dependent on fewer and larger suppliers who can deliver high quality products at competitive prices. Since many decades there is discussion going on about the role of power in chains and marketing channels. In order to understand how power and its interactions with other constructs in the chain... |

| The standard formulas for sample size and power calculation, as implemented in the command sampsi, make use of a normal approximation to the t-distribution. When the sample sizes are small, this approximation is poor, resulting in overestimating power (or underestimating sample size). One particular situation in which this is likely to be important is the field of cluster randomized trials. Although the total number of individuals in a cluster randomized trial may be large, the number of clusters will often be small. We present a simulation study from the design of a cluster randomized crossover trial that motivated this work and a command to perform more accurate sample size and power calculations based on the noncentral t-distribution. |

| Modernity is usually thought as a complex society with clearly differentiated spheres of everyday life. It means, in particular, that economic rules do not interfere with the norms structuring political, social, scientific and other interactions. The complex, differentiated society sharply contrasts with a "small" and homogeneous "pre-modern" society. The process of modernization, i.e. differentiation of the spheres of everyday life, can take various forms. In an advanced country it relies on internal forces. Modernization in this context looks like an evolutionary, "bottom-up" development. In a backward country (Russia and Germany in the first half of the 20th century), modernization requires a strong governmental (from the top to the bottom)... |

| The research topic of power relationships has been receiving increasingly more attention lately. However, only a few scientific works have studied power in the context of supply chain management. In this regard, intriguing research questions arise of how to distinguish among and deal with negative and positive effects of power in order to avoid problems and use power as an effective tool for supply chain management appear to be an important one. An important challenge, therefore, is to find out what role power plays in supply chain networks and how it affects supply chain management with specific attention to coordination and cooperation, and whether power can be utilized as a tool to promote the overall supply chain effectiveness. Therefore, the aim of... |

| In the last years the expression environment and the concern in relation to it became common. However, the environmental question, nowadays a social and sociological problem, has been constructed along human history, gaining new and different aspects and leading to different types of conflicts. Under an apparent “consensus” about the importance of the environment there are power conflicts to define, among others, the meaning of environment, the origin and solutions of the environmental problems and the forms of relations between society and nature, which influence the entire functioning of the society. A first step to advance in the discussion about this theme may be understanding that environment or nature is not so “natural”. Therefore, we propose to... |

| This paper presents a conceptual framework on how institutions of property rights and collective action can contribute to poverty reduction, including through external interventions and action by poor people themselves. The first part of the paper examines the initial conditions of poverty, highlighting the role of assets, risks and vulnerability, legal structures and power relations. The latter part investigates the decision-making dynamics of actors—both poor and non-poor—and how they can use the tangible and intangible resources they have to shape their livelihoods and the institutions that govern their lives. The paper concludes with a discussion of how attention to property rights and collective action can improve the understanding of outcomes in... |
