    Abstract The purpose of this study is to examine the linkage between political skill, emotional labor strategies, and two individual level outcomes; emotional exhaustion and subjective career success in the context of Chinese hotel industry. Political skill is hypothesized to have negative impact on surface acting, conversely, it was hypothesized to have positive impact on deep acting. Similarly, political skill is proposed to positively predict subjective career success and negatively to emotional exhaustion. Interactive effect of political skill with subjective career success and emotional exhaustion as outcome with surface acting as antecedent was also proposed. The emotional labor strategies were also hypothesized with emotional exhaustion and subjective career success as outcome variables. The setting of the study were hotels operating in Wuhan, Peoples' Republic of China. Frontline hotel staff responded 212 questionnaires. Covariance based Structural Equations Modeling was used to conduct the factor analysis and test the hypothesis, AMOS V 20.0 was used for the purpose. Results show that political skill is a positive predictor of subjective career success, and a negative predictor emotional exhaustion. Emotional labor strategies were also related with emotional exhaustion and subjective career success as hypothesized. Political skill confirmed the hypothesized interactive effect with surface acting to predict emotional exhaustion and subjective career success. Lastly, the implications for theory, policy, practice and future research have been given

    Abstract Potato crop, currently, is the staple food crop of about 1.3 billion global population. Potato is attaining even more admiration globally day by day owing to its public acceptability. However, potato sustainable production is distinctly challenged by multiple factors like diseases, pests and climate change etc. Among diseases, common scab is one of the prime threats to potato crop due to its soil-borne nature and versatility in phytotoxins' secretion. Common scab is caused multiple number of phytopathogenic streptomyces strains. Despite extensive research programs, researchers are still unable to identify a significant solution to this threat that is proliferating exceptional rate across the globe. To develop feasible remedies, adequate information regarding host-pathogen interaction should be available. This review possesses insights on existing pathogenic species, the evolution of novel pathogenic streptomyces spp. and phytotoxins produced by the pathogenic strains. Furthermore, which type of physiological, biochemical and genetic activities occur during pathogen's infestation of the host are also canvassed.

    Abstract Fabrication of composites by developing simple techniques can be an efficient way to modify the desire properties of the materials. This paper presents a detailed study on synthesis of low cost and efficient nitrogen doped reduced graphene oxide nickle-silver (N-rGO-Ni/Ag) and nickel-cobalt (N-rGO-Ni/Co) nanocomposites as electrocatalysts in fuel cell using one-pot blended reflux condensation route. An admirable correlation in the structures and properties of the synthesized nanocomposites was observed. The Oxygen Reduction Reaction (ORR) values for N-rGO-Ni/Ag and N-rGO-Ni/Co calculated from the onset potential, using Linear Sweep Voltammetry (LSV), were found to be 1.096 and 1.146. While the half wave potential were determined to be 1.046 and 1.106, respectively, N-rGO-Ni/Ag and N-rGO-Ni/Co. The Tafel and bi-functional (ORR/OER) values were calculated as 76 and 35 mV/decade and 1.23 and 1.12 V, respectively, for N-rGO-Ni/Ag and N-rGO-Ni/Co. The lower onset and half wave potential, low charge transfer resistance (R ct = 1.20 Ω/cm 2 ) and internal solution resistance (R s = 8.84 × 10 −1 Ω/cm 2 ), lower Tafel values (35 mV), satisfactory LSV measurements and mass activity (24.5 at 1.056 V for ORR and 54.9 at 1.056 for OER) demonstrate the remarkable electrocatalytic activity of N-rGO-Ni/Co for both ORR and OER. The chronamperometric stability for synthesized nanocomposites was found satisfactory up to 10 h.

    Abstract Conducting polymers integrated with metal oxides create opportunities for hybrid capacitive electrodes. In this work, we report a one-pot oxidative polymerization for the synthesis of integrated conductive polyindole/nickel oxide (PIn/NiO), polyindole/zinc oxide (PIn/ZnO), and polyindole/nickel oxide/zinc oxide (PNZ). The polymers were analyzed thoroughly for their composition and physical as well as chemical properties by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), ultraviolet–visible spectroscopy (UV–Vis), and thermogravimetric analysis (TGA). The PIn and its composites were processed into electrodes, and their use in symmetrical supercapacitors in two- and three-electrode setups was evaluated by cyclic voltammetry (CV), galvanostatic discharge (GCD), and electrochemical impedance spectroscopy (EIS). The best electrochemical charge storage capability was found for the ternary PNZ composite. The high performance directly correlates with its uniformly shaped nanofibrous structure and high crystallinity. For instance, the symmetrical supercapacitor fabricated with PNZ hybrid electrodes shows a high specific capacitance of 310.9 F g −1 at 0.5 A g −1 with an energy density of 42.1 Wh kg −1 , a power density of 13.2 kW kg −1 , and a good cycling stability of 78.5% after 5000 cycles. This report presents new electrode materials for advanced supercapacitor technology based on these results.

    Abstract Abstract Counter electrode (CE) is an essential part of dye‐sensitized solar cells (DSSCs) in determining their efficiency. Ultimately, the high catalytic activity and conductivity of a CE are dependent on the type of electrode material. The utilization of polyaniline (PANI) coatings for surface modification of CE has proven to be worth. Though it is a bit difficult to optimize the efficiency of a polymeric material, a proper combination of inorganic‐organic dopants can impart positive synergistic effects to the resulting PANI in terms of good conductivity, electrocatalytic activity, and low resistance. This work reports on the effect of the combination ration of an organic dopant (ammonium lauryl sulfate, ALS) and an inorganic dopant (sulfuric acid) on the catalytic activity of CEs modified with PANI for DSSCs. The results are compared with those of platinum counter electrode (Pt CE). The maximum conversion efficiency of DSSC with optimized case reaches 4.54%, which is higher than that of Pt counter electrode (4.02%). This organic–inorganic acids doped polymeric material showing an enhanced photoelectrochemical activity might be exploited in the future as a promising material for application in next‐generation solar devices.

    Abstract Introduction Constipation represents 3% of all office visits to pediatricians and 10% - 45% of consultations with pediatric gastroenterologists. It has been reliably established that the role of abdominal x-rays (AXR) in the diagnosis of constipation in pediatrics is limited; yet, significant overdiagnosis of constipation exists when plain abdominal x-rays are used in the acute setting for abdominal pain or to screen for other disorders. This results in loss of time, resources, exposure to unnecessary radiation, and potentially missing the primary diagnosis. The purpose of this study is to determine the sensitivity and specificity of AXR in diagnosing constipation in the acute setting. Objectives To determine 1) the sensitivity and specificity of plain AXR in the diagnosis of constipation and 2) the effect of age, race, gender, comorbid conditions, and practice setting on the diagnosis of constipation. Methods This study was a historical cohort study of children (two to 18 years of age) who were seen at Ascension St. John Children's Hospital between March 2015 - March 2018 and who had a plain AXR performed during an emergency department (ED) visit or inpatient stay. If AXR results contained keywords, such as "constipation," "stool load," "fecal retention," and "fecal load," the ambulatory medical record, Athena® (http://www.athenahealth.com), was searched to determine if the child had an ambulatory visit in the ensuing 45 days. Chart review was conducted to assess if the diagnosis of constipation was later confirmed by history and physical examination by a pediatrician or gastroenterologist at that visit. By comparing data from both encounters, the sensitivity and specificity of plain AXR in diagnosing constipation was assessed. All data were analyzed using the Statistical Package for Social Sciences (SPSS), v. 25.0 (IBM SPSS Statistics, Armonk, NY) and a p-value of 0.05 or less was considered to indicate statistical significance. Results Over the three-year study period, 1,383 AXRs were performed on 1,116 patients. The sensitivity of AXR in the diagnosis of constipation was 73.8%, specificity 26.8%, positive predictive value 46.4%, and negative predictive value of 54.3%. Pediatric gastroenterologists were more likely to diagnose constipation (63.2%) compared to pediatricians (41.4%) and pediatric surgeons (33.3%) (p = 0.04). Conclusions AXRs are not a reliable means of diagnosing constipation. Overall, we found similar sensitivity and specificity of AXR in diagnosing constipation compared to previous studies. Yet, our study gives new insight into the practices around diagnosing constipation in a single-center community hospital pediatric acute setting and the radiology department. This further emphasizes the need to review current practices and impart more education both in the acute care setting and radiology department.
