Australian Residential Solar Feed-in Tariffs: Industry Stimulus or Regressive Form of Taxation?
Tim Nelson,Paul Simshauser,Simon Kelley
Economic Analysis and Policy , 2011,
Abstract: Feed-in Tariffs (FiT) for residential photovoltaic solar technologies are available inmost Australian jurisdictions. Financial incentives under FiT are in addition to those provided by the Small-Scale Renewable Energy Scheme which forms part of the national 20% Renewable Energy Target. Little attention has been paid to the welfare impacts of FiT on retail electricity prices and social policy objectives. Our analysis indicates that current FiT are a regressive form of taxation. By providing estimates of household impact by income groupings, we conclude that wealthier households are beneficiaries and the effective taxation rate for low income households is three times higher than that paid by the wealthiest households.
Field Application of Processed Manure upon Water Quality and Crop Productivity
Paul Walker,Walt Kelly,Ken Smiciklas,Tim Kelley
Journal of Agronomy , 2009,
Abstract: The purpose of this study was to conduct an applied field study investigating the feasibility of utilizing processed liquid swine manure in crop production. Four treatments were evaluated; unprocessed liquid swine manure, processed liquid effluent, inorganic nitrogen fertilizer and zero-rate control. For shallow subsurface water (as measured by lysimeters), the inorganic nitrogen fertilizer treatment had the greatest levels of nitrate-N. However, there were no significant differences for any measured chemical parameter for groundwater (as measured by sampling wells) among the four treatments. In general, the zero-rate control treatment was the lowest yielding treatment for corn (Zea mays L.), in contrast to the equivalent response of the other treatments. Nutrient accumulation was similar for the four treatments, with the exception of greater plant manganese content of the inorganic nitrogen fertilizer treatment. For soybean (Glycine max L.), all four treatments responded in a similar fashion. After 5 years of annual treatment application, the processed liquid effluent and unprocessed manure treatments were similar for most soil parameters. In addition, soil and plant tissue samples were evaluated for pathogenic organisms (total coliform and Escherichia coli) and non-detectable levels were found for all treatments. The results of this study indicate the processed liquid swine effluent produced in this study, inorganic nitrogen fertilizer and unprocessed manure had similar effects on crop characteristics and subsurface water quality.
Opportunities for nurses in the era of electronic health records  [PDF]

Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.41003

Nursing leaders are currently faced with opportunities to advance nursing’s role in the use of electronic health records (EHRs). Nurse leaders can advance the design of EHRs with nurse informaticists to improve health outcomes of individual and populations of patients.

Investigation of the Relationship between Myopia and Intelligence in a Sample of Undergraduate Students  [PDF]
Michael P. Kelley
Neuroscience & Medicine (NM) , 2011, DOI: 10.4236/nm.2011.24041
Abstract: In a sample of undergraduate students, myopia was associated with higher Math and Total SAT score, and males had higher Math and Total SAT scores than females. The association between myopia and higher Math and Total SAT scores was significant only among males, and the gender differences in Math and Total SAT scores were significant only among allergic participants. There were also significant associations between ethnicity and both myopia and SAT scores, but regression analyses revealed that ethnicity, gender, and myopia each made significant independent contributions to Math SAT scores. The findings provide support for Storfer’s theory of myopia and brain growth.
Cell-extrinsic consequences of epithelial stress: activation of protumorigenic tissue phenotypes

Abstract: The contribution of extrinsic and intrinsic DNA damage to acquisition of desmoplastic phenotypes was investigated in primary human mammary fibroblasts (HMFs) co-cultured with vHMECs with telomere malfunction (TRF2-vHMEC) or in HMFs directly treated with DNA-damaging agents, respectively. Fibroblast reprogramming was assessed by monitoring increases in levels of selected protumorigenic molecules with quantitative polymerase chain reaction, enzyme-linked immunosorbent assay, and immunocytochemistry. Dependence of the induced phenotypes on activin A was evaluated by addition of exogenous activin A or activin A silencing. In vitro findings were validated in vivo, in preinvasive ductal carcinoma in situ (DCIS) lesions by using immunohistochemistry and telomere-specific fluorescent in situ hybridization.HMFs either cocultured with TRF2-vHMEC or directly exposed to exogenous activin A or PGE2 show increased expression of cytokines and growth factors, deposition of extracellular matrix (ECM) proteins, and a shift toward aerobic glycolysis. In turn, these "activated" fibroblasts secrete factors that promote epithelial cell motility. Interestingly, cell-intrinsic DNA damage in HMFs induces some, but not all, of the molecules induced as a consequence of cell-extrinsic DNA damage. The response to cell-extrinsic DNA damage characterized in vitro is recapitulated in vivo in DCIS lesions, which exhibit telomere loss, heightened DNA damage response, and increased activin A and cyclooxygenase-2 expression. These lesions are surrounded by a stroma characterized by increased expression of α smooth muscle actin and endothelial and immune cell infiltration.Thus, synergy between stromal and epithelial interactions, even at the initiating stages of carcinogenesis, appears necessary for the acquisition of malignancy and provides novel insights into where, when, and how the tumor stroma develops, allowing new therapeutic strategies.Cellular responses to stress are complex and vary, dependin
