Turning Theory into Practice: A Case Study in the Arts

Students who take art and music courses learn not only content, but also develop new ways of thinking, communicating, and evaluating. Ultimately, such classes teach students to hear and to see, to be comfortable with ambiguity, to examine issues from multiple perspectives, and to develop sound strategies for working through confusing and sometimes controversial issues.  We argue that the ways of thinking presented in these courses can transfer to any discipline.  This article presents a targeted case study of our experience tailoring a multi-disciplinary arts course specifically to nursing students.  We outline the course construction, document our findings, assess our results, and argue for the benefits of visual and aural training

Nitrogen removal during summer and winter in a primary facultative WSP pond: preliminary findings from 15N-labelled ammonium tracking techniques

Nitrogen removal mechanisms and pathways within WSP have been the focus of much research over the last 30 years. Debates and theories postulated continue to refine our knowledge regarding the cycling and removal pathways for this important nutrient, but a succinct answer has yet to be provided for holistic nitrogen removal. In this study, two experimental runs using labelled 15N as a stable isotope tracking technique were conducted on a pilot-scale primary facultative WSP in the UK; one in the summer of 2006, and the other in the winter of 2007. An ammonium chloride (15NH4Cl) spike was prepared as the slug for each experimental run, which also contained rhodamine WT to act as a dye tracer enabling the hydraulic characteristics of the pond to be mapped. Initial results from the study are reported here, and findings are compared and contrasted. Preliminary findings reveal that a greater proportion of 15N is incorporated into the algal biomass by assimilation and subsequent release as soluble organic nitrogen in summer than in winter. 15N ammonium passes out of the system much sooner and in a much higher proportion in the winter than in summer

ANALYSIS OF THE TAXATION SYSTEM IN ROMANIA IN THE ECONOMIC CRISIS CONTEXT

In this paper we try to realize a study on the interdependencies and correlation between the fiscal policy and financial and economic crisis in Romania. First, we analyze the taxation system in Romania before and after the start of economic crisis to establish the correlation between the level of taxation and the economic growth rate. The sense of correlation is important for analysis the direction of the government fiscal policy in the present context. It is important to follow the major changes of fiscal system after economic crisis beginning to anticipate the opportunity of these fiscal measures in the new economic climate.fiscal policy, financial turmoil, budget deficit, Romanian economy, tax burden.

Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds

A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems. Stable isotope analysis of δ15N showed that nitrification could be considered as an intermediate step in WSP, which is masked by simultaneous denitrification, under conditions of low algal activity. Molecular microbiology analysis showed that denitrification can be considered a feasible mechanism for permanent nitrogen removal in WSP, which may be supported either by ammonia-oxidising bacteria (AOB) or by methanotrophs, in addition to nitrite-oxidising bacteria (NOB). However, the relative supremacy of the denitrification process over other nitrogen removal mechanisms (e.g., biological uptake) depends upon phytoplanktonic activity

Potential Analysis of Promoting the Dengue Hemorrhagic Fever Prevention Through Youtube

Background: Deal with health promotion efforts in terms of disease control using media or social networking is an innovative breakthrough in a region having a broad range of territory, such as Indonesia and others countries alike. The use of social media /video platforms such as youtube, vimeo, veoh in health promotion has been significantly increased. This study aims to determine the potential availability of information about dengue hemorrhagic fever (DHF) on YouTube social media and social media potential of as a medium for dissemination of knowledge of health promotion. Methods: This study used a social media site or website which is the most popular video hosting sites in the world, ‘YouTube', with the keyword of ‘dengue hemorrhagic fever'. The selected video directly associated with DHF, videos in English that were included in this study using Latin letters in the description of the video; with duration less than or equal to 5 minutes. 76 videos analyzed with content analysis methods. Results:Showed that 76 videos divided into categories of prevention, control, transmission, treatment, dengue fever treatment, and other categories. Other information classification categories explain the severity of dengue virus infection, dengue vector (morphology, bionomics), intrinsic phase dengue virus and some research conducted as dengue vaccine discovery efforts. Conclusion: The availability of information about dengue on YouTube social media is still very deficient. Recommendation: YouTube has the potential of social media as a medium for disseminating health promotion information about dengue

A Far-infrared Characterization of 24 μm Selected Galaxies at 0 < z < 2.5 using Stacking at 70 μm and 160 μm in the COSMOS Field

We present a study of the average properties of luminous infrared galaxies detected directly at 24 μm in the COSMOS field using a median stacking analysis at 70 μm and 160 μm. Over 35,000 sources spanning 0 ≤ z ≤ 3 and 0.06 mJy ≤ S_(24) ≤ 3.0 mJy are stacked, divided into bins of both photometric redshift and 24 μm flux. We find no correlation of S_(70)/S_(24) flux density ratio with S_(24), but find that galaxies with higher S_(24) have a lower S_(160)/S_(24) flux density ratio. These observed ratios suggest that 24 μm selected galaxies have warmer spectral energy distributions (SEDs) at higher mid-IR fluxes, and therefore have a possible higher fraction of active galactic nuclei. Comparisons of the average S_(70)/S_(24) and S_(160)/S_(24) colors with various empirical templates and theoretical models show that the galaxies detected at 24 μm are consistent with "normal" star-forming galaxies and warm mid-IR galaxies such as Mrk 231, but inconsistent with heavily obscured galaxies such as Arp 220. We perform a χ^2 analysis to determine best-fit galactic model SEDs and total IR luminosities for each of our bins. We compare our results to previous methods of estimating L IR and find that previous methods show considerable agreement over the full redshift range, except for the brightest S_(24) sources, where they overpredict the bolometric IR luminosity at high redshift, most likely due to their warmer dust SED. We present a table that can be used as a more accurate and robust method for estimating bolometric infrared luminosity from 24 μm flux densities

Retrospective Evaluation of the Epidemiology and Practice Variation of Dexmedetomidine Use in Invasively Ventilated Pediatric Intensive Care Admissions, 2007-2013

OBJECTIVES: The study assessed dexmedetomidine utilization and practice variation over time in ventilated pediatric intensive care unit (PICU) patients; and evaluated differences in hospital outcomes between high- and low-dexmedetomidine utilization hospitals. STUDY DESIGN: This serial cross-sectional analysis used administrative data from PICU admissions in the pediatric health information system (37 US tertiary care pediatric hospitals). Included admissions from 2007 to 2013 had simultaneous dexmedetomidine and invasive mechanical ventilation charges, <18 years of age, excluding neonates. Patient and hospital characteristics were compared as well as hospital-level severity-adjusted indexed length of stay (LOS), charges, and mortality. RESULTS: The utilization of dexmedetomidine increased from 6.2 to 38.2 per 100 ventilated PICU patients among pediatric hospitals. Utilization ranged from 3.8 to 62.8 per 100 in 2013. Few differences in patient demographics and no differences in hospital-level volume/severity of illness measures between high- and low-utilization hospitals occurred. No differences in hospital-level, severity-adjusted indexed outcomes (LOS, charges, and mortality) were found. CONCLUSION: Wide practice variation in utilization of dexmedetomidine for ventilated PICU patients existed even as use has increased sixfold. Higher utilization was not associated with increased hospital charges or reduced hospital LOS. Further work should define the expected outcome benefits of dexmedetomidine and its appropriate use
