External sources of clean technology: evidence from the clean development mechanism
New technology is fundamental to sustainable development. However, inventors from industrialized countries often refuse technology transfer because they worry about reverse-engineering. When can clean technology transfer succeed? We develop a formal model of the political economy of North–South technology transfer. According to the model, technology transfer is possible if (1) the technology in focus has limited global commercial potential or (2) the host developing country does not have the capacity to absorb new technologies for commercial use. If both conditions fail, inventors from industrialized countries worry about the adverse competitiveness effects of reverse-engineering, so technology transfer fails. Data analysis of technology transfer in 4,894 projects implemented under the Kyoto Protocol’s Clean Development Mechanism during the 2004–2010 period provides evidence in support of the model
Color No Longer A Sign of Bondage: Race, Identity and the First Kansas Colored Volunteer Infantry Regiment (1862-1865)
"Color No Longer A Sign of Bondage" is an account of the First Kansas Colored Volunteer Infantry Regiment from its earliest days in 1862 to the regiment's triumphant return to Kansas in November 1865. This work encompasses the racial attitudes of the black and white communities of Kansas, Indian Territory, and Arkansas, and the military service of the regiment through campaigns in the service of the Union's Army of the Frontier. The evolution of white support for black enlistment in Kansas, the regiment's acceptance by white Union regiments, and the concurrent conflicts with Confederate sympathizers and military organizations are central themes of this work. Although black military service in the Union was not officially countenanced in Kansas prior to 1863 and the Emancipation Proclamation, the First Kansas Colored fought for recognition and shed blood despite the opposition of Kansas civil and military authorities alike. The irregular enlistment and employment of the regiment jeopardized its existence through the fall of 1862, and despite official disapproval the regiment survived to become a vital part of the Army of the Frontier. White and black Kansans alike took note of the regiment's military service and through the sterling service of the regiment in an unforgiving theater of war, the regiment won the admiration of white regiments and a skeptical black civil populace. The deeds of the First Kansas Colored in battle and in garrison ultimately undergirded the black drive for civil rights and proved that black men could serve as soldiers in an army that often relegated its black soldiers to fatigue duty. The First Kansas Colored was a fighting regiment that won honors in Kansas, Indian Territory, and Arkansas and by its actions demanded respect. The manhood denied to blacks prior to the Civil War was not won through legal battles, but through courageous conduct in war and the blood shed by its soldiers in combat. The First Kansas Colored never faltered in its service to the Union; nor did it fail its supporters and the families of those who served in its ranks. The First Kansas Colored proved that color was no longer a sign of bondage and, although recognition for its deeds often proved ephemeral, its legacy endures
Striving for a Happier America: Lessons from Denmark
American society has lost sight of one of its most valued virtues: Happiness. Research has showed that the United States is behind many other countries in the overall happiness of its citizens. Leading the world in well-being is Denmark. This paper’s aim is to explore possible factors that could be facilitating the well-being of Danish citizens, and applying them to American society. In this search, I explore universal individual factors, as well as factors that lead to the development of a culture and dispositions of its citizens. From these factors, as well as unique characteristics of both countries, I hypothesized determinates of well-being in Demark, as well as factors that are detrimental to American’s well-being. Factors for Demark include uniform cultural ideals, social equality, social programs, and unique perspectives on happiness. Conversely, the lack or low levels of these factors for Americans might attest to lower well-being. By emulating these Danish policies and ideals, the U.S. could produce happier, less stressed Americans
Clustering and Alignment of Polymorphic Sequences for HLA-DRB1 Genotyping
Located on Chromosome 6p21, classical human leukocyte antigen genes are highly polymorphic. HLA alleles associate with a variety of phenotypes, such as narcolepsy, autoimmunity, as well as immunologic response to infectious disease. Moreover, high resolution genotyping of these loci is critical to achieving long-term survival of allogeneic transplants. Development of methods to obtain high resolution analysis of HLA genotypes will lead to improved understanding of how select alleles contribute to human health and disease risk. Genomic DNAs were obtained from a cohort of n = 383 subjects recruited as part of an Ulcerative Colitis study and analyzed for HLA-DRB1. HLA genotypes were determined using sequence specific oligonucleotide probes and by next-generation sequencing using the Roche/454 GSFLX instrument. The Clustering and Alignment of Polymorphic Sequences (CAPSeq) software application was developed to analyze next-generation sequencing data. The application generates HLA sequence specific 6-digit genotype information from next-generation sequencing data using MUMmer to align sequences and the R package diffusionMap to classify sequences into their respective allelic groups. The incorporation of Bootstrap Aggregating, Bagging to aid in sorting of sequences into allele classes resulted in improved genotyping accuracy. Using Bagging iterations equal to 60, the genotyping results obtained using CAPSeq when compared with sequence specific oligonucleotide probe characterized 4-digit genotypes exhibited high rates of concordance, matching at 759 out of 766 (99.1%) alleles. © 2013 Ringquist et al
Differentiating Literacy Instruction Through Guided Reading
Research reiterates how instilling a strong reading foundation in young students is vital to their growth in the future. Today, students need more support and individualized education to meet the diverse needs students enter school with. Whole group reading instruction does not benefit students in comparison to differentiated instruction. In order to differentiate instruction to meet the needs of the students as well as provide scaffolds to enhance literacy, teachers must incorporate small group instruction such as guided reading groups.
Guided reading are groups of students around the same developmental level that showcase similar learning needs exploring books. Teachers work alongside students, coaching through strategies, word work, fluency and comprehension reading skills. Students working in a social setting, building on skills with support from the teacher working to their full potential. Guided reading groups teach important reading skills before reading, during reading and after reading. Although guided reading is not a curriculum in and of itself, teachers must understand its importance and its place in the classroom. Persuasive information and providing examples will inspire teachers to incorporate a reading instruction format that is grounded in providing the best instruction to each individual child
Crystal structure of the Legionella pneumophila Lpg2936 in complex with the cofactor S-adenosyl-L-methionine reveals novel insights into the mechanism of RsmE family methyltransferases
The methylationlation of U1498 located in the 16S ribosomal RNA of Escherichia coli is an important modification affecting ribosomal activity. RsmE methyltransferases methylate specifically this position in a mechanism that requires an S-adenosyl-L-methionine (AdoMet) molecule as cofactor. Here we report the structure of Apo and AdoMet-bound Lpg2936 from Legionella pneumophila at 1.5 Å and 2.3 Å, respectively. The protein comprises an N-terminal PUA domain and a C-terminal SPOUT domain. The latter is responsible for protein dimerization and cofactor binding. Comparison with similar structures suggests that Lpg2936 is an RsmE-like enzyme that can target the equivalent of U1498 in the L. pneumophila ribosomal RNA, thereby potentially enhancing ribosomal activity during infection-mediated effector production. The multiple copies of the enzyme found in both structures reveal a flexible conformation of the bound AdoMet ligand. Isothermal titration calorimetry measurements suggest an asymmetric two site binding mode. Our results therefore also provide unprecedented insights into AdoMet/RsmE interaction, furthering our understanding of the RsmE catalytic mechanism. This article is protected by copyright.

Amino Acid Position 11 of HLA-DRβ1 is a Major Determinant of Chromosome 6p Association with Ulcerative Colitis
The major histocompatibility complex (MHC) on chromosome 6p is an established risk locus for ulcerative colitis (UC) and Crohn’s disease (CD). We aimed to better define MHC association signals in UC and CD by combining data from dense single nucleotide polymorphism (SNP) genotyping and from imputation of classical HLA types, their constituent SNPs and corresponding amino acids in 562 UC, 611 CD, and 1,428 control subjects. Univariate and multivariate association analyses were performed, controlling for ancestry. In univariate analyses, absence of the rs9269955 C allele was strongly associated with risk for UC (P = 2.67×). rs9269955 is a SNP in the codon for amino acid position 11 of HLA-DRβ1, located in the P6 pocket of the HLA-DR antigen binding cleft. This amino acid position was also the most significantly UC-associated amino acid in omnibus tests (P = 2.68×). Multivariate modeling identified rs9269955-C and 13 other variants in best predicting UC versus control status. In contrast, there was only suggestive association evidence between the MHC and CD. Taken together, these data demonstrate that variation at HLA-DRβ1, amino acid 11 in the P6 pocket of the HLA-DR complex antigen binding cleft is a major determinant of chromosome 6p association with ulcerative colitis

Superfund, Hedonics, and the Scales of Environmental Justice
Environmental justice (EJ) is prominent in environmental policy, yet EJ research is plagued by debates over methodological procedures. A well-established economic approach, the hedonic price method, can offer guidance on one contentious aspect of EJ research: the choice of the spatial unit of analysis. Environmental managers charged with preventing or remedying inequities grapple with these framing problems. This article reviews the theoretical and empirical literature on unit choice in EJ, as well as research employing hedonic pricing to assess the spatial extent of hazardous waste site impacts. The insights from hedonics are demonstrated in a series of EJ analyses for a national inventory of Superfund sites. First, as evidence of injustice exhibits substantial sensitivity to the choice of spatial unit, hedonics suggests some units conform better to Superfund impacts than others. Second, hedonic estimates for a particular site can inform the design of appropriate tests of environmental inequity for that site. Implications for policymakers and practitioners of EJ analyses are discussed
