Poverty and Nonprofits: Investigating the Relationship Between Poverty and Nonprofit Activity in the United States
In order to better understand our society and institutions, we can look at the relationships between institutions, social infrastructure, and human conditions. Social and institutional networks can influence the flow of resources on a scale that individuals cannot. These structures can perpetuate or alleviate social and human conditions but, alternatively, social conditions can mobilize and influence institutional structures. As systemic poverty remains a social issue, various US programs and forms of aid continue to be delivered despite limiting and varying levels of success. One such mode of aid is provided by nonprofits. Studies have shown that nonprofits empirically do very little to alleviate poverty. Instead they behave more as temporary relief programs, providing some basic and fundamental services but not enough to make large strides in reducing poverty. Given this research and others that have examined this relationship as a top-down system where nonprofit actions influence poverty, this research is focused on considering the opposite model. Perhaps instead, poverty is a driver for institutional change. Given a societal problem, the problem itself could influence structures and the flow of resources from a bottom-up perspective. This research evaluates whether poverty is correlated to the activities of nonprofits and the relationship between the two. An empirical model examines the role of poverty on the activities of community-based nonprofits and whether nonprofits are responding to poverty. The data examined include a nationwide survey of community-based nonprofits organized at a microscale. The results show that given last year’s poverty, there is an increase in nonprofit activity this year, exhibiting a strong, positive relationship between the two. This research suggests that community-based relief may instead be a response to poverty regardless of whether nonprofits are effective in reducing poverty
Solvent Degradation and Emissions from a 0.7MWe Pilot CO\u3csub\u3e2\u3c/sub\u3e Capture System with Two-Stage Stripping
The UKy-CAER team successfully tested an advanced 0.7 MWe post-combustion CO2 capture system on a coal-fired power plant using a heat integration process combined with two-stage stripping to enhance the CO2 absorber performance. One of the unique feature of the UKy-CAER integrated process is a two-stage stripping unit for solvent regeneration. The secondary stripper is empowered by the heat rejection from a conventional steam-heated (primary) stripper. The secondary stripper outlet stream at the commercial scale can be used as boiler secondary combustion air, consequently enriching the flue gas with CO2, resulting in less energy penalty required by the CO2 capture system. The primary goal of this study was to form an initial assessment of the impact on the amine solvent from coal combustion flue gas contaminants and the potential higher oxygen content in the solvent due to incorporation of the secondary air stripper into the conventional amine scrubber/stripper system. The overall oxidative degradation was comparable to previous reports with 30 wt% MEA solvent at similar flue gas run hours. This suggests that the addition of the secondary air stripper appears to be negligible with regards to solvent oxidation
Automated Reminders to Promote Radon Testing in a Lung Cancer Case Control Study
One of the four pilot projects of the Lung Cancer Initiative sponsored by the Department of Defense measures radon levels in the participants homes. Radon exposure is the second leading cause of Lung Cancer. The case-control study has a targeted accrual of 1800 with a case-control ratio of 1:4. The long-term radon kits remain in the home for 90 days and the participants are asked to mail the test kit to the company for analysis. In order to maximize the test kit return rate, reminder calls to the participants occurred 90 days after the home visit

Theorising Global Governance Inside Out: A Response to Professor Ladeur
Professor Ladeur argues that administrative law’s postmodernism (and by extension Global Administrative Law) necessitates that we move beyond relying on ideas of delegation, account- ability and legitimacy. Global Governance, particularly Global Administrative Law and Global Constitutionalism, should try to adapt and experiment with the changing nature of the postmod- ern legality and support the creation of norms that will adapt to the complexities of globalisation. Ladeur’s contestation, similar to GAL’s propositions, can be challenged. By taking the International Criminal Tribunal for Rwanda, a significant contributor to the field of international criminal law, as an example, it is suggested that the creation of networks that Ladeur makes visible may not account for ‘regulatory capture’. This paper will argue that from the outside, the proliferation of networks may suggest that spontaneous accountability is possible. A closer look, however, drawing on anthropological insights from the ICTR, reveals that international institutions are suscepti- ble to capture by special interests. Furthermore, there are two central themes that animate the response to Professor Ladeur: the political nature of international institutions and the history of international law, and the role of institutions in this history
Global prevalence and disease burden of vitamin D deficiency: a roadmap for action in low- and middle-income countries.
Vitamin D is an essential nutrient for bone health and may influence the risks of respiratory illness, adverse pregnancy outcomes, and chronic diseases of adulthood. Because many countries have a relatively low supply of foods rich in vitamin D and inadequate exposure to natural ultraviolet B (UVB) radiation from sunlight, an important proportion of the global population is at risk of vitamin D deficiency. There is general agreement that the minimum serum/plasma 25-hydroxyvitamin D concentration (25(OH)D) that protects against vitamin D deficiency-related bone disease is approximately 30Â nmol/L; therefore, this threshold is suitable to define vitamin D deficiency in population surveys. However, efforts to assess the vitamin D status of populations in low- and middle-income countries have been hampered by limited availability of population-representative 25(OH)D data, particularly among population subgroups most vulnerable to the skeletal and potential extraskeletal consequences of low vitamin D status, namely exclusively breastfed infants, children, adolescents, pregnant and lactating women, and the elderly. In the absence of 25(OH)D data, identification of communities that would benefit from public health interventions to improve vitamin D status may require proxy indicators of the population risk of vitamin D deficiency, such as the prevalence of rickets or metrics of usual UVB exposure. If a high prevalence of vitamin D deficiency is identified (>20% prevalence of 25(OH)D 1%), food fortification and/or targeted vitamin D supplementation policies can be implemented to reduce the burden of vitamin D deficiency-related conditions in vulnerable populations
Distinct phenotypes of three-repeat and four-repeat human tau in a transgenic model of tauopathy.
Tau exists as six closely related protein isoforms in the adult human brain. These are generated from alternative splicing of a single mRNA transcript and they differ in the absence or presence of two N-terminal and three or four microtubule binding domains. Typically all six isoforms have been considered functionally similar. However, their differential involvement in particular tauopathies raises the possibility that there may be isoform-specific differences in physiological function and pathological role. To explore this, we have compared the phenotypes induced by the 0N3R and 0N4R isoforms in Drosophila. Expression of the 3R isoform causes more profound axonal transport defects and locomotor impairments, culminating in a shorter lifespan than the 4R isoform. In contrast, the 4R isoform leads to greater neurodegeneration and impairments in learning and memory. Furthermore, the phosphorylation patterns of the two isoforms are distinct, as is their ability to induce oxidative stress. These differences are not consequent to different expression levels and are suggestive of bona fide physiological differences in isoform biology and pathological potential. They may therefore explain isoform-specific mechanisms of tau-toxicity and the differential susceptibility of brain regions to different tauopathies
Altered versican cleavage in ADAMTS5 deficient mice : a novel etiology of myxomatous valve disease
AbstractIn fetal valve maturation the mechanisms by which the relatively homogeneous proteoglycan-rich extracellular matrix (ECM) of endocardial cushions is replaced by a specialized and stratified ECM found in mature valves are not understood. Therefore, we reasoned that uncovering proteases critical for ‘remodeling’ the proteoglycan rich (extracellular matrix) ECM may elucidate novel mechanisms of valve development. We have determined that mice deficient in ADAMTS5, (A Disintegrin-like And Metalloprotease domain with ThromboSpondin-type 1 motifs) which we demonstrated is expressed predominantly by valvular endocardium during cardiac valve maturation, exhibited enlarged valves. ADAMTS5 deficient valves displayed a reduction in cleavage of its substrate versican, a critical cardiac proteoglycan. In vivo reduction of versican, in Adamts5−/− mice, achieved through Vcan heterozygosity, substantially rescued the valve anomalies. An increase in BMP2 immunolocalization, Sox9 expression and mesenchymal cell proliferation were observed in Adamts5−/− valve mesenchyme and correlated with expansion of the spongiosa (proteoglycan-rich) region in Adamts5−/− valve cusps. Furthermore, these data suggest that ECM remodeling via ADAMTS5 is required for endocardial to mesenchymal signaling in late fetal valve development. Although adult Adamts5−/− mice are viable they do not recover from developmental valve anomalies and have myxomatous cardiac valves with 100% penetrance. Since the accumulation of proteoglycans is a hallmark of myxomatous valve disease, based on these data we hypothesize that a lack of versican cleavage during fetal valve development may be a potential etiology of adult myxomatous valve disease
Effect of Duration and Intermittency of Rifampin on Tuberculosis Treatment Outcomes: A Systematic Review and Meta-Analysis
In a systematic review of randomized controlled trials on tuberculosis treatment, Dick Menzies and colleagues find shorter courses of rifampin to be associated with poorer treatment outcomes
Finishing the euchromatic sequence of the human genome
The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
