Publishing should be more about culture than book sales

This article argues that publishing should be studied as a social and cultural practice rather than merely a business

We need creative teaching to teach creativity

This article discusses whether or not creativity can be taught

Play scripts as knowledge objects

This paper outlines the ways that play writing acts as a research method and plays can be understood as knowledge objects or research outcomes. It also argues that Playwriting Studies, an emerging research field, is best conceived as a sub-discipline situated within the Creative Writing discipline

Self-publishing matters – don’t let anyone tell you otherwise

This article argues that self-publishing is a significant cultural and economic phenomena that needs further scholarly attention

Digestion of Protein in Premature and Term Infants.

Premature birth rates and premature infant morbidity remain discouragingly high. Improving nourishment for these infants is the key for accelerating their development and decreasing disease risk. Dietary protein is essential for growth and development of infants. Studies on protein nourishment for premature infants have focused on protein requirements for catch-up growth, nitrogen balance, and digestive protease concentrations and activities. However, little is known about the processes and products of protein digestion in the premature infant. This review briefly summarizes the protein requirements of term and preterm infants, and the protein content of milk from women delivering preterm and at term. An in-depth review is presented of the current knowledge of term and preterm infant dietary protein digestion, including human milk protease and anti-protease concentrations; neonatal intestinal pH, and enzyme activities and concentrations; and protein fermentation by intestinal bacteria. The advantages and disadvantages of incomplete protein digestion as well as factors that increase resistance to proteolysis of particular proteins are discussed. In order to better understand protein digestion in preterm and term infants, future studies should examine protein and peptide fragment products of digestion in saliva, gastric, intestinal and fecal samples, as well as the effects of the gut micro biome on protein degradation. The confluence of new mass spectrometry technology and new bioinformatics programs will now allow thorough identification of the array of peptides produced in the infant as they are digested

U.S. Climate Policy Developments

This paper outlines recent developments in U.S. climate policies. Although the United States does not participate in the Kyoto Mechanism, a number of climate policies are being implemented at state level as well as at the federal level. First, we report and compare the federal cap and trade proposals in the 110th Congress. Then, the paper illustrates the current situations of state level climate policies, such as the Regional Greenhouse Gas Initiative in the northeastern states or AB32 in California. We analyze these proposals from the viewpoint of technology policies and impacts on international markets. It is found that technology policies play important roles in the cap and trade proposals and that there is a great expectation for carbon capture and sequestration (CCS) technology. In terms of the impacts on international markets, several federal proposals as well as regional programs permit trading in international markets. As emission targets become more stringent in the future, U.S. GHG emitters are more likely to interact with these markets. Thus, despite the lack of U.S. participation in the Kyoto Protocol, U.S. markets will be linked to foreign markets, at least, in an indirect way.United States, climate policy, cap and trade, the Kyoto mechanism, technology policy

Relative importance of host environment, transmission potential and host phylogeny to the structure of parasite metacommunities

Identification of mechanisms that shape parasite community and metacommunity structures have important implications to host health, disease transmission, and the understanding of community assembly in general. Using a long-term dataset on parasites from desert rodents, we examined the relative contributions of host traits that represent important aspects of parasite environment, transmission probability between host species, and host phylogeny to the structure of a parasite metacommunity as well as for taxonomically restricted parasite metacommunities (coccidians, ectoparasites and helminths). This was done using a combination of metacommunity analysis and variance partitioning based on canonical correspondence analysis. Coccidian and ectoparasite metacommunities did not exhibit coherent structure. In contrast, helminths and the full parasite metacommunity had Clementsian and quasi-Clementsian structure, respectively, indicating that parasite species distributions for these metacommunities were compartmentalized along a dominant gradient. Variance decomposition indicated that characteristics associated with the host environment consistently explained more variation than did host traits associated with transmission opportunities or host phylogeny, indicating that the host environment is primary in shaping parasite species distributions among host species. Moreover, the importance of different types of host traits in structuring parasite metacommunities was consistent among taxonomic groups (i.e. full metacommunity, coccidians, and helminths) despite manifest differences in emergent structures (i.e. Clementsian, quasi-Clementsian, and random) that arose in response to variation in host environment. © 2014 The Authors
