Drawing lines at the sand: evidence for functional vs. visual reef boundaries in temperate Marine Protected Areas.
Marine Protected Areas (MPAs) can either protect all seabed habitats within them or discrete features. If discrete features within the MPA are to be protected humans have to know where the boundaries are. In Lyme Bay, SW England a MPA excluded towed demersal fishing gear from 206 km(2) to protect rocky reef habitats and the associated species. The site comprised a mosaic of sedimentary and reef habitats and so 'non reef' habitat also benefited from the MPA. Following 3 years protection, video data showed that sessile Reef Associated Species (RAS) had colonised sedimentary habitat indicating that 'reef' was present. This suggested that the functional extent of the reef was potentially greater than its visual boundary. Feature based MPA management may not adequately protect targeted features, whereas site based management allows for shifting baselines and will be more effective at delivering ecosystem goods and services
Making the Portland way of planning: the structural power of language : stories from community planning, 1969-2001
Thesis (Ph. D.)--University of Washington, 2003Portland, Oregon has attracted continuing attention for its achievements in planning, urban design, and growth management, and for its participatory approach to this work. They have stopped freeways, rebuilt their downtown, resurrected neighborhoods, built public transit, designed urban villages, and drawn urban growth boundaries. More than that, over the course of more than three decades they have built an extensive and powerful structure of planning for neighborhoods, downtown, the city, and the metropolitan region. This dissertation examines in detail two episodes in this process---the Northwest District Plan (1969--1977) and the Southwest Community Plan (1994--2001)---as a means of demonstrating how this structure is actually the cultural product of the concerted mobilization of meaning through the use of language in planning, organizing, democratizing and institutionalizing these practice. To suggest that language has structural power is to recast the arguments about the character and status of ostensible structural determinants of action
Actor-Networks, Farmer Decisions, and Identity
Climate change and industrial agricultural practices pose threats to the future of Kansas agriculture. To inform the debate about sustainable agriculture that must soon occur, we seek to illuminate the factors involved in the decision making of farmers in Kansas. Drawing from Actor–Network Theory, we consider how farmers’ participation in the industrial agricultural network shapes their decisions, defines the types of knowledge and skills that are valued by farmers and others in the network, transforms what it means to be a Kansas grain farmer, and entrenches unsustainable production practices

What Can We Learn from Rodents about Prolactin in Humans?
Prolactin (PRL) is a 23-kDa protein hormone that binds to a single-span membrane receptor, a member of the cytokine receptor superfamily, and exerts its action via several interacting signaling pathways. PRL is a multifunctional hormone that affects multiple reproductive and metabolic functions and is also involved in tumorigenicity. In addition to being a classical pituitary hormone, PRL in humans is produced by many tissues throughout the body where it acts as a cytokine. The objective of this review is to compare and contrast multiple aspects of PRL, from structure to regulation, and from physiology to pathology in rats, mice, and humans. At each juncture, questions are raised whether, or to what extent, data from rodents are relevant to PRL homeostasis in humans. Most current knowledge on PRL has been obtained from studies with rats and, more recently, from the use of transgenic mice. Although this information is indispensable for understanding PRL in human health and disease, there is sufficient disparity in the control of the production, distribution, and physiological functions of PRL among these species to warrant careful and judicial extrapolation to humans
