AFFECTION OF CSR TO JOB SATISFACTION MEDIATED BY QUALITY OF WORK LIFE (CASE STUDY OF FOUR STAR HOTEL IN INDONESIA)

The purpose of this study is to discuss the perceptions of employees in the hospitality industry on corporate social responsibility and their influence on employee job satisfaction which is mediated by the quality of life of employees. This study hypothesizes about employee job satisfaction with corporate social responsibility mediated by the quality of work life. The population in this study consisted of the hotel industry with 4-star classes working for companies where CSR practices. Methods of data collection include the distribution of survey questionnaires. Using samples taken from four-star hotel employees in DKI Jakarta Indonesia, 175 samples were used as samples for analysis using the Structural Equation Model. The results showed that there are influences of each dimension of CSR (legal, economy, ethical, philanthropic) to the quality of work life. This study also shows the influence of employee job satisfaction to the quality of work-life of employees. There is a mediation of the quality of work-life between CSR dimensions to job satisfaction. This research is expected that the company can find out the needs that must be met by the company for job satisfaction of its employees through CSR activities

A brief review of the literature on the malignant ureteral obstruction

Malignant ureteral obstruction (MUO) caused by a primarily urological tumor or secondary to a late-stage malignancy can be difficult for the urologist to manage. Due to a lack of clinical data on the management of MUO, every case is particular and should be aborted individually. Lack of specific treatment, either palliative or definitive, can severely damage renal function and lifetime expectancy in patients, causing even more damage that could otherwise be avoided. Prompt management directed at the recovery of renal function is the main goal in such cases. Even after urinary flow is restored, life threatening post-obstructive diuresis needs to be managed

The impact of biomass withdrawal strategy on the biomass selection and polyhydroxyalkanoates accumulation of mixed microbial cultures

UIDP/04378/2020 UIDB/04378/2020 LA/P/0140/2020 SFRH/BD/110673/2015The production of polyhydroxyalkanoates (PHA) by mixed microbial cultures (MMC) has been studied as an alternative to pure cultures in order to reduce the price of PHA through use of open systems and low-cost substrates, such as agro-industrial sub-products. However, the widespread applicability of this process depends on the optimization of operational factors impacting PHA productivity. This study addresses the impact of biomass withdrawal strategy on the performance of MMC selection reactors and consequently on biomass productivity and global PHA productivity. Two selection reactors were operated in parallel under similar conditions, except for the timing of biomass withdrawal, at the end of the famine phase (Reactor 1, R1) versus at the end of the feast phase (Reactor 2, R2) at an organic loading rate of 100 Cmmol.L−1.d−1 and solids retention time of 4 days. The biomass selected in both conditions had similar PHA storing capacity as shown by the similar yields of PHA per substrate obtained in the accumulation assays; however, R1 reached a higher biomass productivity (about 4-fold higher than R2). This study demonstrated that removing the excess biomass at the end of the famine phase resulted in a much higher global PHA productivity and that the key parameter affecting the global PHA productivity of the 2-stage system was the volumetric biomass productivity. Results obtained provide important insight into how MMC systems can be best operated to maximize PHA productivity.publishersversionpublishe

User perceptions of sound quality: implications for the design and use of audio-based mobile applications

This study sought to investigate the effect that contextual cues (in particular, device type and content type) have on the perception of sound quality. A sample of 49 participants were tested on different mobile devices sizes (small – iPhone, medium – iPad Mini, and large – iPad) which had identical sound output characteristics within in different usage contexts (generic content vs. musical training app contexts). Results showed that the users’ perception of generic sound types was affected by device type, with iPhones appearing to have better sound quality compared to larger devices. On the other hand, within application contexts, the application type seemed to affect user perceptions more, with the rhythm training application rating poorer on sound quality, picture quality, and likelihood of future use as compared to the pitch training application (although this may be due to the perceived increased difficulty). Together, these findings demonstrate the influence of device and content cues (when actual physical qualities are controlled) on user sound perception. Interestingly, differences in perceived sound quality was not accompanied by an overriding preference for that device as compared to other devices. Instead, considerations such as ease of use seemed to drive considerations for uptake of applications

The impact of pH on the anaerobic and aerobic metabolism of Tetrasphaera-enriched polyphosphate accumulating organisms

Funding Information: The authors thank the Portuguese Fundaçao para a Ciência e a Tecnologia, which supports the Applied Molecular Biosciences Unit - UCIBIO, the European Commission (Water JPI project 196 (Water-Works2014 ERA-NET Co-funded Call): “Smart decentralized water management through a dynamic integration of technologies (Watintech)” and the Australian Research Council ( ARC LP190100329 ). Publisher Copyright: © 2023Members of the genus Tetrasphaera are putative polyphosphate accumulating organisms (PAOs) that have been found in greater abundance than Accumulibacter in many full-scale enhanced biological phosphorus removal (EBPR) wastewater treatment plants worldwide. Nevertheless, previous studies on the effect of environmental conditions, such as pH, on the performance of EBPR have focused mainly on the response of Accumulibacter to pH changes. This study examines the impact of pH on a Tetrasphaera PAO enriched culture, over a pH range from 6.0 to 8.0 under both anaerobic and aerobic conditions, to assess its impact on the stoichiometry and kinetics of Tetrasphaera metabolism. It was discovered that the rates of phosphorus (P) uptake and P release increased with an increase of pH within the tested range, while PHA production, glycogen consumption and substrate uptake rate were less sensitive to pH changes. The results suggest that Tetrasphaera PAOs display kinetic advantages at high pH levels, which is consistent with what has been observed previously for Accumulibacter PAOs. The results of this study show that pH has a substantial impact on the P release and uptake kinetics of PAOs, where the P release rate was >3 times higher and the P uptake rate was >2 times higher at pH 8.0 vs pH 6.0, respectively. Process operational strategies promoting both Tetrasphaera and Accumulibacter activity at high pH do not conflict with each other, but lead to a potentially synergistic impact that can benefit EBPR performance.publishersversionpublishe

The workday of hospital surgeons: what they do, what makes them satisfied, and the role of core tasks and administrative tasks; a diary study.

BACKGROUND Many surgeons report passion for their work, but not all tasks are likely to be satisfying. Little is known about how hospital surgeons spend their days, how they like specific tasks, and the role of core tasks (i.e. surgery-related tasks) versus tasks that may keep them from core tasks (e.g., administrative work). This study aimed at a more detailed picture of hospital surgeons' daily work - how much time they spend with different tasks, how they like them, and associations with satisfaction. METHODS Hospital surgeons (N = 105) responded to a general survey, and 81 of these provided up to five daily questionnaires concerning daily activities and their attractiveness, as well as their job satisfaction. The data were analyzed using t-tests, analysis of variance, as well as analysis of covariance and repeated measures analysis of variance for comparing means across tasks. RESULTS Among 14 tasks, surgery-related tasks took 21.2%, patient-related tasks 21.7% of the surgeons' time; 10.4% entailed meetings and communicating about patients, and 18.6% documentation and administration. The remaining time was spent with teaching, research, leadership and management, and not task-related activities (e.g. walking between rooms). Surgery was rated as most (4.25; SD = .66), administration as least attractive (2.63; SD = .78). A higher percentage of administration predicted lower perceived legitimacy; perceived legitimacy of administrative work predicted job satisfaction (r = .47). Residents were least satisfied; there were few gender differences. CONCLUSIONS Surgeons seem to thrive on their core tasks, most notably surgery. By contrast, administrative duties are likely perceived as keeping them from their core medical tasks. Increasing the percentage of medical tasks proper, notably surgery, and reducing administrative duties may contribute to hospital surgeons' job satisfaction

Polyphosphates and poly-β-hydroxybutyrate granules identification through quantitative image analysis in enhanced biological phosphorus removal systems

Enhanced biological phosphorus removal (EBPR) is a widely implemented technique for having the potential to cheaply and reliably remove phosphate from wastewater treatment processes, than traditional chemical methods. EBPR is performed by operating the system sequentially with anaerobic and aerobic conditions. Several studies were already performed ranging from different strategies for the competition between polyphosphate accumulating organisms (PAOs) and glycogen accumulating organisms (GAOs) to modeling both types of bacterial activities. Until now, slight attention has been given to the development of newer, faster, simpler, and better suited monitoring techniques for this type of system. This work is focused on the development of image analysis techniques for polyphosphates and poly-β-hydroxybutyrate granules in EBPR systems since off-line analyses are labor intensive and not able to be performed in full-scale plants. A lab-scale sequencing batch reactor fed with synthetic wastewater containing volatile fatty acids (VFAs) and orthophosphate was used. The reactor had a working volume of 4 L and was operated with a cycle time of 6 h consisting of 2 h anaerobic, 3 h aerobic, 50 min settling and decanting, and 5 min anaerobic idle periods. In each cycle, 2 L of synthetic wastewater was fed to the reactor in the first 5 min of the anaerobic period, resulting in a hydraulic retention time (HRT) of 12 h. The pH was controlled during both the anaerobic and aerobic periods around 7, and the temperature was controlled at 30 ºC in order to provide selective advantages to GAOs over PAOs. The ratio between chemical oxygen demand (COD) and P in the feed was kept at 10 (gCOD/g P). Biomass samples were collected at the end of the anaerobic and aerobic phases and fixed with phosphate buffer saline solution (PBS) and ethanol. Two fluorescence staining methods were used: (1) DAPI for poly-P identification; and (2) nile blue for poly-β-hydroxybutyrate granules. So far, promising results were achieved regarding the type of images achieved by these fluorescence staining methods and the image analysis procedures still under development
