Ups and Downs: Does the American Economy Still Promote Upward Mobility?

Examines trends in absolute intragenerational mobility by analyzing short- and long-term income fluctuations from 1967-2004, rates of recovery from declines, recovery time, and rates of gains compared with those of declines

TIMBER HARVEST ADJACENCY ECONOMIES, HUNTING, SPECIES PROTECTION, AND OLD GROWTH VALUE: SEEKING THE OPTIMUM

Spatial forest management models recognize that nontimber benefits cat1 be influenced by the status of adjacent land. For instance, contiguous old growth provides habitat, aesthetic value, and environmental services. Conversely, edge areas provide forage and cover habitat for game and non-game wildlife. However, adjacency externalities are not limited to nontimber concerns. Larger harvest areas generate average cost savings as fixed harvesting costs are spread across greater acreage, a problem excluded from most literature on optimal harvesting. Hence, it is typical that economies and diseconomies of adjacency in harvesting occur simultaneously. This complicates the determination of optimal ecosystem management behavior, which recognizes timber, aesthetic, wildlife protection, and hunting values. This paper conceptually portrays economies of adjacency in competing objectives using multiple management strategies.Resource /Energy Economics and Policy,

U.S. BIOMASS SUPPLY FOR ELECTRICITY GENERATION: CLIMATE POLICY IMPLICATIONS AND CARBON NEUTRALITY

This paper investigates three important energy and climate policy issues: (1) the availability of biomass for electricity generation (i.e., supply), (2) climate policy effects on this supply, and (3) the net greenhouse gas reduction when biomass is used for electricity generation. Using a detailed model of U.S. agriculture and forestry markets and land-use, that includes a broad and diverse set of biomass feedstocks, we evaluate competing potential sub-national and feedstock specific supplies of biomass for U.S. electricity generation. Our preliminary results suggest significant supply, with residues dominating at lower delivered energy prices, and dedicated crops significant at higher prices. Sub-national variation is dramatic and will affect generation siting and sustainability. We find displacement of food crops, but net forest land and cropland expansion. We also find that GHG policies could substantially increase the delivered cost of biomass; however, the implications for individual regions and feedstocks is non-uniform, with some supplies falling to zero and others increasing. Finally, we find that bioelectricity is not carbon neutral, but can be emissions reducing relative to coal generation, yield greater direct GHG benefits than biofuels, and even result in domestic indirect emissions reductions with incentives for forest based feedstocks.Agricultural and Food Policy, Environmental Economics and Policy, Land Economics/Use, Resource /Energy Economics and Policy,

Blueprint for Learning: Constructing College Courses to Facilitate, Assess, and Document Learning is an outstanding faculty development tool. It neither overcomplicates nor oversimplifies instructional design, and it provides numerous illustrations and references, making it a well-rounded tool. It would be best utilized as a study guide for faculty interested in engaging, learner-centered, accountable instruction

Glycan analysis of the chicken synaptic plasma membrane glycoproteins - a major synaptic N-glycan carries the LewisX determinant

The majority of plasma membrane components are glycosylated. It is now widely accepted that this post-translational modification is crucial during the establishment, maintenance and function of the nervous system. Despite its significance, structural information about the glycosylation of nervous system specific glycoproteins is very limited. In the present study the major glycan structure of the chicken synaptic plasma membrane (SPM) associated glycoprotein glycans were determined. N-glycans were released by hydozinnolysis, labelled with 2-aminobenzam,ide, treated with neuraminidase and subsequently fractionated by size exclusion chromatography. Individual fractions were characterized by combination of high-pressure liquid chromatography, exoglicosidase treatment or reagent array analysis method (RAAM). In addition to oligomannose-type glycans, core-fucosylated complex glycans with biantennary bisecting glycans carrying the LewisX epitope were most abundant. The overall chicken glycan profile was strikingly similar to the rat brain glycan profile. The presence of the LewisX determinant in relatively large proportions suggests a tissue-specific function for these glycans

A brief history of the British Neuroscience Association

As the British Neuroscience Association commemorates 50 years of existence in 2018, this article recalls its founding as a discussion group, its establishment as the Brain Research Association, its transition to a professional society encompassing all aspects of neuroscience research, both clinical and non-clinical, and its re-branding as the British Neuroscience Association in the late 1990s. Neuroscience as a branch of life science has expanded hugely in the last 25 years and the British Neuroscience Association has adapted, frequently working with partner societies, to serve as an interdisciplinary hub for professionals working in this exciting and crucial field. The authors have attempted to highlight some key events in the Association’s history and acknowledge the contributions made by many people over half a century

Moving Forward with the Responsibility to Protect: Using Political Inertia to Protect Civilians

First formulated in 2005, the Responsibility to Protect has emerged onto the international legal landscape. This doctrine recently was expressed in the 2011 United Nations-authorized humanitarian intervention in Libya. Despite this promising start, the doctrine—designed to protect civilians from violence caused by their government or violence which the government is powerless to stop—has done nothing for the civilians in Syria. This Note explores the history of the Responsibility to Protect, identifies its flaws, analyzes proposed reforms, and ends with a suggested revision to the doctrine. This suggested revision would allow the political inertia of states to work for, rather than against, civilians
