High Temperature Sinter

Slightly alkaline hot springs and geysers in Yellowstone National Park exhibit distinctive assemblages of high-temperature (>73 °C) siliceous sinter reflecting local hydrodynamic conditions. The main depositional zones include subaqueous pool and channel bottoms and intermittently wetted subaerial splash, surge, and overflow areas. Subaqueous deposits include particulate siliceous sediment and dendritic and microbial silica framework. Silica framework forms thin, porous, microbe-rich films coating subaqueous surfaces. Spicules with intervening narrow crevices dominate in splash zones. Surge and overflow deposits include pool and channel rims, columns, and knobs. In thin section, subaerial sinter is composed of (i) dark brown, nearly opaque laminated sinter deposited on surfaces that evaporate to dryness; (ii) clear translucent silica deposited subaqueously through precipitation driven by supersaturation; (iii) heterogeneous silica representing silica-encrusted microbial filaments and detritus; and (iv) sinter debris. Brownish laminations form the framework of most sinter deposited in surge and overflow zones. Pits and cavities are common architectural features of subaerial sinter and show concave-upward pseudo-cross-laminations and micro-unconformities developed through migration. Marked birefringence of silica deposited on surfaces that evaporate to dryness is probably a strain effect. Repeated wetting and evaporation, often to dryness, and capillary effects control the deposition, morphology, and microstructure of most high-temperature sinter outside of the fully subaqueous zone. Microbial filaments are abundant on and within high-temperature sinter but do not provide the main controls on morphology or structuring except in biofilms developed on subaqueous surfaces. Millimetre-scale lamination cyclicity in much high-temperature sinter represents annual layering and regular seasonal fluctuations in silica sedimentation.

AbstractDifferent theories have been posited that try to explain the decision-making process of smallholders especially regarding the adoption of new technologies or new agricultural techniques. The objective of this paper is to review and re-assess the dominant household production theories to explain the decision making of smallholders practicing conservation agriculture (CA) in the southern, eastern, and central provinces of Zambia. It also discusses the potential role of CA toward economic development. It finds that the CA smallholders studied did not aim to maximize profits but tried to secure household consumption from their own production before any other considerations in risky and uncertain environments. Their response to economic incentives was contingent on minimizing risks associated with securing a minimum level of livelihood and investing into local forms of insurance. This paper concludes that the ability for CA to contribute to rural livelihoods and economic development would depend on how adequately the factors that hinder smallholder agricultural development in general are addressed.

Systems Modelling

Plant health is relatively poorly funded compared with animal and human health issues. However, we contend it is at least as complex and likely more so given the number of pests and hosts and that outbreaks occur in poorly monitored open systems. Modelling is often suggested as a method to better consider the threats to plant health to aid resource and time poor decision makers in their prioritisation of responses. However, like other areas of science, the modelling community has not always provided accessible and relevant solutions. We describe some potential solutions to developing plant health models in conjunction with decision makers based upon a recent example and illustrate how an increased emphasis on plant health is slowly expanding the potential role of modelling in decision making. We place the research in the Credibility, Relevance and Legitimacy (CRELE) framework and discuss the implications for future developments in co-construction of policy-linked models.

In riverine forest of Chitwan National Park, Nepal, Bhellar or trewia (Trewia nudiflora) is one of the most abundant tree species. Similarly, chital (Axis axis) is the most abundant and widely distributed deer species. We documented the potential role of chital in seed dispersal of trewia tree in Chitwan. We observed the trewia seeds regurgitated by chital at the Gharial Conservation and Breeding Center (GCBC), Kasara, Chitwan. The trewia seeds were recorded the following morning of the chital sheltering the GCBC. A detailed study is suggested to understand trewia the seed germination success and trewia-chital relationship.

The Belgian Presidency is generally seen as being a success. On many difficult questions, the Belgians succeeded in forging compromises between the member states. There is a risk however, that the apparent successes of this Presidency will lead to an over-estimation of the role which a EU-president can play. Therefore, it is important to pay attention to its limits and possibilities. It can help to relativize the Belgian presidency and to improve insights into the potential role of EU-presidents within the decision-making of the European Union.

This chapter shows how a particular kind of meeting, called in isiZulu the indaba, contributes toBatho Pele, an African values-based practice. First, it explores the challenge of values diversity, including what it means to respect diversity of values, and the different responses to the challenge from regulatory ethics and from values-based practice. It then explores the challenge of diversity in an African context through the story of a real (though biographically disguised) person, Ms. Precious Pelo, her family members and clinicians. Ms. Pelo’s story shows the need for substantive (process-focused) rather than merely executive (outcomes-focused) communicative processes in responding to the challenge of values diversity in clinical decision-making. Finally, it describes part of an indaba convened for Ms. Pelo, its opening minutes illustrating many of the key features ofBatho Pele. We conclude with an indication of the potential role of indabas in other areas of values-based practice.
