Power of person-job fit: Emotional labour for salespeople and its relation to job satisfaction

This study focused on the effect of person-job fit on the relationship between emotional labour and job satisfaction among salespeople in Turkey. Using survey data obtained from 204 salespeople working in different sectors, we analysed job satisfaction, person-job fit and three components of emotional labour, which are deep acting, surface acting and naturally felt emotions. We found that job satisfaction has a significant relationship positively with naturally felt emotions and negatively with surface acting. Although no significant moderation effect has been found for person-job fit, we found that person-job fit significantly mediates the relationship between job satisfaction and naturally felt emotions as well as the one between job satisfaction and surface acting. © Copyright 2017 Inderscience Enterprises Ltd

Synthesis and characterization of sulfonated homo- and co-polyimides based on 2,4 and 2,5-diaminobenzenesulfonic acid for proton exchange membranes

A series of sulfonated homo- and random co-polyimides (co-SPI) based on 2,4-diaminobenzene-sulfonic acid (2,4-DABS) and 2,5-diaminobenzenesulfonic acid (2,5-DABS) has been synthesized via conventional two-step polyimidization method. 2,4-DABS and 2,5-DABS were used as sulfonated diamine compounds, 4,4'-oxydianiline (ODA) and 4,4'-diaminodiphenyl sulfone (DDS) were used as non-sulfonated diamine compounds. Mixtures of sulfonated and non-sulfonated diamine compounds were reacted with benzophenonetetracarboxylic dianhydride (BTDA) to obtain co-SPI membranes. Molar ratios of sulfonated to non-sulfonated diamine were systematically varied to produce copolymers of controlled compositions. The co-SPIs were evaluated for thermal oxidative stability, ion exchange capacity (IEC), water uptake, proton conductivity, solubility, and hydrolytic stability. Proton conductivity and hydrolytic stability of the co-SPIs were compared with the fully aromatic polyimide, homo-SPIs (BTDA/2,4-DABS and BTDA/2,5-DABS). Regarding thermogravimetric analysis (TGA) analysis, it is concluded that desulfonation temperature in the range of 200-350 degrees C suggests high stability of sulfonic acid groups. co-SPIs with 40 mol% of 2,4-DABS showed similar or higher proton conductivity than Nafion (R) 117 in water. Proton conductivity values of the co-SPIs were mainly a function of IEC and water uptake. Consequently, the optimum concentration of 2,4-DABS was found to be in the range of 30-40 mol% from the viewpoint of proton conductivity, IEC, and hydrolytic stability.

Preparation of Yttria-Stabilized Zirconia by the Reverse Microemulsion Method and the Effect of Sc and Ce Doping on Microstructure and Ionic Conductivity for Solid Oxide Fuel Cell Applications

In this study, 8 mol% yttria-stabilized zirconia (8YSZ), ceria-, and scandia-doped YSZ powders were synthesized by the reverse microemulsion method. The powders were calcined at 1000 degrees C and sintered at 1450 degrees C. The crystalline properties and microstructure of the samples were characterized by X-ray diffraction and SEM methods, respectively. Oxygen ionic conductivities of the samples were measured by electrochemical impedance spectroscopy in the temperature range 250-375 degrees C. Grain interior and grain boundary resistivities were also calculated. Particle sizes of YSZ and Sc-doped YSZ were found to be < 100 nm, while that of Ce-doped YSZ was 120-150 nm. Approximately 1 mu m grains were observed after sintering of YSZ at 1450 degrees C. Particularly, the grain boundary and also the grain interior resistivities decreased with 3% scandia-doped YSZ. It was observed that the total conductivity of 3YSZ was higher than that of 3% ceria-doped YSZ

Preparation and characterization of sulfonated polyimide ionomers via post-sulfonation method for fuel cell applications

This paper describes our work on the synthesis of a series of sulfonated homo-/co-polyimides (SPI) which were obtained by post-sulfonation method over three steps. In the first step, 4,4'-oxydianiline (ODA) and 4,4'-diaminodiphenylsulfone (DDS) dissolved in N-methyl pyrrolidone (NMP) were reacted with benzophenonetetracarboxylic dianhydride (BTDA) in order to yield poly(amic acid) (PAA). Secondly, precipitated PAA was sulfonated via concentrated sulfuric acid (95-98%) at room temperature to give post-sulfonated PAA (PSPAA). Finally, PSPAA was converted into post-sulfonated PI (PSPI) by the thermal imidization method. PSPIs with ion exchange capacity (IEC) ranging from 0.20 to 0.67meq/g were prepared. The thermal properties of the PSPIs were evaluated and high desulfonation temperature was found in the range of 190-350 degrees C, suggesting the high stability of sulfonic acid groups. In water, PSPI-5 membrane displayed similar proton conductivity to Nafion (R) 117, whereas this membrane showed poor conductivity in dry state. All PSPIs displayed good solubility in common polar aprotic solvents such as NMP and dimethylacetamide (DMAc). Furthermore, the effects of post-sulfonation reaction on chemical structure, thermal oxidative behavior, and physical properties of the PSPI membranes such as membrane quality/stability and water uptake were discussed.

Nosocomial infections in neonatal units in Turkey: epidemiology, problems, unit policies and opinions of healthcare workers

WOS: 000276572900008PubMed ID: 20402067Turkish Neonatal Society Nosocomial Infections Study Group. Nosocomial infections in neonatal units in Turkey: epidemiology, problems, unit policies and opinions of healthcare workers. Turk J Pediatr 2010; 52: 50-57. The epidemiology of nosocomial infections in Turkish neonatal intensive care units (NICUs) shows that nosocomial sepsis is an important problem, especially for very low birth weight (VLBW) infants, and gram-negative agents, particularly Klebsiella species, are still the major causes of nosocomial infections. Sepsis frequency was 6.4%, ranging from 2.1 to 17%, in 16 centers in Turkey. Sepsis frequency was 22% in infants 2500 g. Sepsis-related mortality was 24.4 for 100 sepsis cases, ranging from 0 to 75 for 100 cases. Ventilator-associated pneumonia frequency was 1.7%, catheter-related infection frequency was 0.14% and urinary tract infection frequency was 3.7%. Healthcare workers (HCWs) complain of the inadequacy of some basic facilities and of staffing; however, they are aware of the causes and solutions and are willing to overcome this major health problem. We conclude that Turkish neonatal HCWs are quite optimistic about preventing neonatal nosocomial infections

Prevalence of Anosmia in 10.157 Pediatric COVID-19 Cases: Multicenter Study from Turkey.

Introduction: COVID-19-related anosmia is a remarkable and disease-specific finding. With this multicenter cohort study, we aimed to determine the prevalence of anosmia in pediatric cases with COVID-19 from Turkey and make an objective assessment with a smell awareness questionnaire. Material and Methods: This multicenter prospective cohort study was conducted with pediatric infection clinics in 37 centers in 19 different cities of Turkey between October 2020 and March 2021. The symptoms of 10.157 COVID-19 cases 10-18 years old were examined. Age, gender, other accompanying symptoms, and clinical severity of the disease of cases with anosmia and ageusia included in the study were recorded. The cases were interviewed for the smell awareness questionnaire at admission and one month after the illness. Results: Anosmia was present in 12.5% (1.266/10.157) of COVID-19 cases 10-18 years of age. The complete records of 1053 patients followed during the study period were analyzed. The most common symptoms accompanying symptoms with anosmia were ageusia in 885 (84%) cases, fatigue in 534 cases (50.7%), and cough in 466 cases (44.3%). Anosmia was recorded as the only symptom in 84 (8%) of the cases. One month later, it was determined that anosmia persisted in 88 (8.4%) cases. In the smell awareness questionnaire, the score at admission was higher than the score one month later (P < 0.001). Discussion: With this study, we have provided the examination of a large case series across Turkey. Anosmia and ageusia are specific symptoms seen in cases of COVID-19. With the detection of these symptoms, it should be aimed to isolate COVID-19 cases in the early period and reduce the spread of the infection. Such studies are important because the course of COVID-19 in children differs from adults and there is limited data on the prevalence of anosmia
