    The text in this paper is written in the form of a poem. The purpose of this paper is to draw attention to the destruction of value and passion of research by presenting the elements that are ruining this passion. The inspiration of this was Parker and Guthrie’s (2019) comment that accounting research suffered when science dominated universities privileged the science and medicine focussed impact factors, when most of the accounting journals were not even included in the rankings. The poem is written in free verse, which mimics the nuances and cadences of spoken English. Frequent media coverage of university rankings and outcomes of research assessment exercises and the close monitoring of academic research grants and publications have become fashionable clichés. The poem is an outcome of careful collection and coordination of different research papers that have highlighted the impact of research assessment exercises. The ideas shared in the poem ring so true to the hearts of the authors who are accounting scholars themselves

    Trans-acting mutations in loci other than kdpDE that affect kdp operon regulation in Escherichia coli: effects of cytoplasmic thiol oxidation status and nucleoid protein H-NS on kdp expression

    Transcription of the K+ transport operon kdp in Escherichia coli is induced during K+-limited growth by the action of a dual-component phosphorelay regulatory system comprised of a sensor kinase (integral membrane protein), KdpD, and a DNA-binding response regulator (cytoplasmic protein), KdpE. In this study, we screened for new dke (named dke for decreased kdp expression) mutations (in loci other than kdpDE) that led to substantially decreased kdp expression. One dke mutation was shown to be in hns, encoding the nucleoid protein H-NS. Another dke mutation was mapped to trxB (encoding thioredoxin reductase), and an equivalent reduction in kdp expression was demonstrated also for trxA mutants that are deficient in thioredoxin 1. Exogenously provided dithiothreitol rescued the kdp expression defect in trxB but not trxA mutants. Neither trxB nor trxA affected gene regulation mediated by another dual-component system tested, EnvZ-OmpR. Mutations in genes dsbC and dsbD did not affect kdp expression, suggesting that the trx effects on kdp are not mediated by alterations in protein disulfide bond status in the periplasm. Reduced kdp expression was observed even in a trxB strain that harbored a variant KdpD polypeptide bearing no Cys residues. A trxB hns double mutant was even more severely affected for kdp expression than either single mutant. The dke mutations themselves had no effect on strength of the signal controlling kdp expression, and constitutive mutations in kdpDE were epistatic to hns and trxB. These results indicate that perturbations in cytoplasmic thiol oxidation status and in levels of the H-NS protein exert additive effects, direct or indirect, at a step(s) upstream of KdpD in the signal transduction pathway, which significantly influence the magnitude of KdpD kinase activity obtained for a given strength of the inducing signal for kdp transcription

    After studying the fact of emerging advancement in the e-commerce sector we come with an idea of developing project based on the combination of virtual reality and augmentation. To create a web and mobile based platform for end user which will give them a new shopping experience. We are making a web based e-commerce platform where consumer can interact with product such as shoes or clothes at their home place. This will not going required any costly sensor just they have to use their computer and web-cam/ Kinect to interact with the website 3D portal.Our Project will be useful for day to day user to have interaction with the product or services they buy from e-commerce market place prior to actually buying product. They can choose from different product or services they like. And this will be beneficial to manufacturer also to analysis there market plans and production

    Dexmedetomidine premedication in cataract surgery under topical anaesthesia: to assess patient and surgeon satisfaction

    Background: Dexmedetomidine is a potent non-opioid analgesic that may enhance analgesia for cataract surgery under topical anaesthesia. This study was undertaken to assess sedation and analgesia provided by dexmedetomidine and evaluating patients’ satisfication. Secondary aims were: (1) To study the effect of dexmedetomidine in decreasing the intraocular pressure. (2) The impact on surgeons' satisfaction. (3) Hemodynamic effectsMethods: We conducted a prospective randomized study on ASA I/II patients presenting for cataract surgery under topical anesthesia. Patients were randomly assigned to two groups: group D received dexmedetomidine premedication 1 mcg/kg over 10 minutes and group C received saline at the same rate. Sedation and pain score, intraocular pressure, patient and surgeon satisfaction score and hemodynamics were monitored and compared.Results: There was a significant increase in sedation assessed by the Ramsay sedation score at all times in group D after receiving dexmedetomidine (p< 0.0001). However, pain scores (numeric rating scale) were similar in both groups (p>0.05). Dexmedetomidine decreased the intraocular pressure and the difference was statistically highly significant (p< 0.0001). Group D had better patient and surgeon satisfaction score as against group C (p=0.0001). Noticably, the incidence of dry mouth was higher in group D. Hemodynamic parameters were well maintained in both groups with no adverse events in either group. Conclusions: Dexmedetomidine can be used safely for cataract surgery under topical anesthesia surgery. Administration of dexmedetomidine was associated with better patient and surgeon satisfaction

    Effect of incubation time and substrate concentration on N-uptake rates by phytoplankton in the Bay of Bengal

    International audienceWe report here the results of three experiments, which are slight variations of the 15N method (JGOFS protocol) for determination of new production. The first two test the effect of (i) duration of incubation time and (ii) concentration of tracer added on the uptake rates of various N-species (nitrate, ammonium and urea) by marine phytoplankton; while the third compares in situ and deck incubations from dawn to dusk. Results indicate that nitrate uptake can be underestimated by experiments where incubation times shorter than 4h or when more than 10% of the ambient concentration of nitrate is added prior to incubation. The f-ratio increases from 0.28 to 0.42 when the incubation time increases from two to four hours. This may be due to the observed increase in the uptake rate of nitrate and decrease in the urea uptake rate. Unlike ammonium [y{=}2.07x{-}0.002\, (r2=0.55)] and urea uptakes [y{=}1.88x{+}0.004 (r2=0.88)], the nitrate uptake decreases as the concentration of the substrate (x) increases, showing a negative correlation [y{=}-0.76x+0.05 (r2=0.86)], possibly due to production of glutamine, which might suppress nitrate uptake. This leads to decline in the f-ratio from 0.47 to 0.10, when concentration of tracer varies from 0.01 to 0.04? M. The column integrated total productions are 519 mg C m-2 d-1 and 251 mg C m-2 d-1 for in situ and deck incubations, respectively. The 14C based production at the same location is ~200 mg C m-2 d-1, which is in closer agreement to the 15N based total production measured by deck incubation

    Objective: Otolaryngic disorders are very common in primary care, comprising 20–50% of presenting complaints to a primary care provider. There is limited otolaryngology training in undergraduate and post-graduate medical education for primary care. Presented at the American Academy of Otolaryngology – Head & Neck Surgery 2011 Annual Meeting, San Francisco, USA, on Tuesday, September 13, 2011. Continuing medical education may be the next opportunity to train our primary care providers (PCPs). The objective of this study was to assess the otolaryngology knowledge of a group of PCPs attending an otolaryngology update course. Methods: PCPs enrolled in an otolaryngology update course completed a web-based anonymous survey on demographics and a pre-course knowledge test. This test was composed of 12 multiple choice questions with five options each. At the end of the course, they were asked to evaluate the usefulness of the course for their clinical practice. Results: Thirty seven (74%) PCPs completed the survey. Mean knowledge test score out of a maximum score of 12 was 4.0±1.7 (33.3±14.0%). Sorted by area of specialty, the mean scores out of a maximum score of 12 were: family medicine 4.6±2.1 (38.3±17.3%), pediatric medicine 4.2±0.8 (35.0±7.0%), other (e.g., dentistry, emergency medicine) 4.2±2.0 (34.6±17.0%), and adult medicine 3.9±2.1 (32.3±17.5%). Ninety one percent of respondents would attend the course again. Conclusion: There is a low level of otolaryngology knowledge among PCPs attending an otolaryngology update course. There is a need for otolaryngology education among PCPs
