Complete Genome Sequence of a Divergent Human Rhinovirus C Isolate from an Infant with Severe Community-Acquired Pneumonia in Colorado, USA.
Here, we report the genome sequence of a divergent human rhinovirus C isolate identified from an infant with a severe community-acquired respiratory infection. RNA sequencing performed on an Illumina platform identified reads aligning to human rhinovirus species, which were de novo assembled to produce a coding-complete genome sequence
Sustainable Recycling of Insoluble Rust Waste for the Synthesis of Iron-Containing Perovskite-Type Catalysts
Insoluble rust waste from the scraping of rusted iron-containing materials represents a cheap, eco-friendly, and available source of iron. LaFeO3 perovskite-type powders were successfully prepared by solution combustion synthesis using rust waste from an electricity transmission tower manufacturer. Solution combustion synthesis enabled introduction of this insoluble iron precursor directly into the final product, bypassing complex extraction procedures. Catalytic activity in the propylene oxidation of the waste-derived LaFeO3 with stoichiometric Fe/La ratio was almost identical to the commercial iron nitrate-derived LaFeO3 , thus demonstrating the viability of this recycling solution. The amount of waste iron precursor was varied and its effect on the powder properties was investigated. A lesser stoichiometric amount of precursor produced a LaFeO3 -La2O3 binary system, whereas a higher stoichiometric amount led to a LaFeO3 -Fe2O3 binary system. Catalytic activity of iron-rich compositions in the propylene oxidation was only slightly lower than the stoichiometric one, whereas iron-poor compositions were much less active. This eco-friendly methodology can be easily extended to other iron perovskites with different chemical compositions and to other iron-containing compounds

Attributions of blame in sexual harassment incidents : an honors thesis (HONRS 499)
Perceptions of culpability in situations in which a male professor engages in sexual harassment of a female student were studied. Specifically, the influence of subject gender, latency of reporting, and severity of harassment on subjects' perceptions of sexual harassment was studied. Introductory psychology students (186 females, 106 males) read one of twelve vingettes and then completed a two-part questionnaire on their perceptions of the situation portrayed in the vignette. A 2 X 3 x 4 between-subjects factorial analysis was performed. As hypothesized, subject gender and severity of harassment significantly affected perceptions of sexual harassment. Females viewed the incidents more negatively than did males. Subjects viewed harassment incidents of greater severity more negatively than those incidents of less severity. Latency of reporting did not appear to affect subjects' perceptions of sexual harassment.Honors CollegeThesis (B.?.
Strontium and iron-doped barium cobaltite prepared by solution combustion synthesis: exploring a mixed-fuel approach for tailored intermediate temperature solid oxide fuel cell cathode materials
Ba0.5Sr0.5Co0.8Fe0.2O3–δ (BSCF) powders were prepared by solution combustion synthesis using single and double fuels. The effect of the fuel mixture on the main properties of this well-known solid oxide fuel cell cathode material with high oxygen ion and electronic conduction was investigated in detail. Results showed that the fuel mixture significantly affected the area-specific resistance of the BSCF cathode materials, by controlling the oxygen deficiency and stabilizing the Co2+ oxidation state. It was demonstrated that high fuel-to-metal cations molar ratios and high reducing power of the combustion fuel mixture are mainly responsible for the decreasing of the area-specific resistance of BSCF cathode materials. Moreover, a new metastable monoclinic phase with Ba0.5Sr0.5CO3 composition was discovered in the as-burned BSCF powders, enlarging the existing information on the BSCF phase formation mechanis

The Influence of Administrative Supervision on Counselor Subordinates: Uncharted Territory
The purpose of this dissertation is to convey research on counselors’ experience of administrative supervision. While research in counseling has given much attention to clinical supervision and the relationship between clinical supervisor and supervisee, it has not adequately attended to the important and influential role of administrative supervision and its impacts on counselor subordinates. There is limited research and literature that suggests administrative supervision is important to the welfare of counselor subordinates, such as in burnout prevention, and also important to counselor subordinates’ job performance, which can have an impact on client welfare. However, no research was found in the field of counseling that directly examines administrative supervision’s effects. This study addresses a gap in counseling research by utilizing qualitative grounded theory methodology to shine a light on how therapists experience administrative supervision. Primary categories that developed from this study included counselors evaluating administrative supervisors, administrative supervisors’ alignment with counseling principles, counselors responding to conditions of administrative supervision, and impacts on counselors professionally and personally. The major finding of the study involved the generation of a grounded theory to explain how participants experienced administrative supervision. Participants described their experience of administrative supervision as a process of evaluating their administrative supervisors through a lens of idealism formed in their personal backgrounds, but further refined and strengthened by their graduate training and education. Participants went into agency work with strong ideals that were often disappointed by the administrative supervision they received. To navigate this, they responded by performing the work, relating to others, and taking personal actions. When administrative supervisors aligned with participants’ ideals, participants experienced positive effects on their work performance, commitment to the profession, relationships with others, and personal well-being; but when they experienced mis-alignment, they experienced negative impacts in these areas. Member checking confirmed that participants felt the generated grounded theory captured their experiences and also that it helped them put words to what they felt but had not been able to articulate. In conclusion, the developed grounded theory of this study did explain how the participants experience administrative supervision, helped the participants put words to their experiences, and provides a foundation for future research and attention to this neglected area of counseling practice
Macrophytes as indicators of land-derived wastewater : application of a δ15N method in aquatic systems

The definitive version was published in Water Resources Research 41 (2005): W01014, doi:10.1029/2004WR003269.We measured δ15N signatures of macrophytes and particulate organic matter (POM) in six estuaries and three freshwater ponds of Massachusetts to assess whether the signatures could be used as indicators of the magnitude of land-derived nitrogen loads, concentration of dissolved inorganic nitrogen in the water column, and percentage of N loads contributed by wastewater disposal. The study focused specifically on sites on Cape Cod and Nantucket Island, in the northeastern United States. There was no evidence of seasonal changes in δ15N values of macrophytes or POM. The δ15N values of macrophytes and POM increased as water column dissolved inorganic nitrogen concentrations increased. We found that δ15N of macrophytes, but not of POM, increased as N load increased. The δ15N values of macrophytes and groundwater NO3 tracked the percent of wastewater contribution linearly. This research confirms that δ15N values of macrophytes and NO3 can be excellent indicators of anthropogenic N in aquatic systems.This work was supported by funds from the

Adhesive and Rheological Features of Ecofriendly Coatings with Antifouling Properties
In this work, formulations of "environmentally compatible" silicone-based antifouling, synthesized in the laboratory and based on copper and silver on silica/titania oxides, have been characterized. These formulations are capable of replacing the non-ecological antifouling paints currently available on the market. The texture properties and the morphological analysis of these powders with an antifouling action indicate that their activity is linked to the nanometric size of the particles and to the homogeneous dispersion of the metal on the substrate. The presence of two metal species on the same support limits the formation of nanometric species and, therefore, the formation of homogeneous compounds. The presence of the antifouling filler, specifically the one based on titania (TiO2) and silver (Ag), facilitates the achievement of a higher degree of cross-linking of the resin, and therefore, a better compactness and completeness of the coating than that attained with the pure resin. Thus, a high degree of adhesion to the tie-coat and, consequently, to the steel support used for the construction of the boats was achieved in the presence of the silver-titania antifouling
