Workplace Bullying and Turnover Intention: Moderating Role of Abusive Supervision among Employees of Nepali Commercial Banks

Background: Organizations are facing many explicit and implicit costs associated with the voluntary turnover of high-performing employees. Voluntary turnover is detrimental to organizational growth and success. Therefore, employers and practitioners try to understand what motivates people to leave. Negative employee behaviors such as workplace bullying and abusive supervision have been identified as critical variables for employee motivation to leave. Purpose: The purpose of the paper was to investigate the moderating role of Abusive Supervision in relation to Workplace Bullying and Turnover Intention among employees in Nepali Commercial Banks. Research Methodology: This paper applied a quantitative approach and cross-sectional survey research design to investigate the research objective. The convenience sampling method was employed to research employees of different commercial banks. Data were collected from 202 employees via self-administered questionnaires. Covariance-Based Structure Equation Modeling (CB-SEM) was applied to examine research hypotheses. Results: The result showed that Workplace Bullying positively influences Turnover Intention among employees of Nepali commercial banks. Also, the result showed that Abusive Supervision moderates the relationship between Workplace Bullying and Turnover Intention. Conclusion: According to the paper, employees of Nepali commercial banks intend to leave their respective banks if they experience Workplace Bullying at a different level of Abusive Supervision. Increasing Abusive Supervision in the presence of Workplace Bullying increases the intention of leaving commercial banks. Implications: This paper has two implications. Theoretically, this paper provides a critical juncture for Nepali researchers by investing in moderating the role of Abusive Supervision on turnover intention. Managerially, it is imperative for organizations to invest in enriching their employees by creating a work environment free of bullying and abusive supervision. Originality: This paper stands at a critical juncture in Nepali research because it is among the fewest studies investigating the moderating role of abusive supervision on workplace bullying and turnover intention.
In Vitro Selection and Extended Culture of Antigen-Specific T Lymphocytes

Functional selection of antigen-specific T lymphocytes can be achieved by culturing thymus-dependent (T) lymphocytes from immunized guinea pigs on “monolayers” of antigen-pulsed adherent peritoneal exudate cells (PEC) from nonimmune syngeneic donors. Several aspects of the in vitro selection of T lymphocyte-rich peritoneal exudate lymphocytes (PEL) were studied. It was shown that irradiated adherent PEC were equivalent to nonirradiated adherent PEC in supporting selection cultures, indicating that the lymphocytes harvested at the end of the selection culture derive from the immune donors of the PEL and not from the nonimmune donor of the adherent PEC. The relative importance of specific adherence and specific proliferation for achieving selection was determined by comparing the degree of selection obtained when nonadherent cells were discarded at 24 hr with that noted when the discard step was omitted. It was found that omitting the discard step markedly diminished the degree of selection. On the other hand, blocking proliferation with specific alloantisera after the discard step did not diminish the degree of selection, although it did diminish the cell yield. Thus, specific adherence to antigen-pulsed PEC appeared to be critical in the selection culture procedure. An estimate of the degree of enrichment obtained by the selection culture procedure was obtained by culturing selected cells in an excess of nonprimed PEL, so that auxiliary cells would not be limiting. Under these conditions, it appeared that selected cells were enriched from 4-to 10-fold in antigen-responsive cells with respect to the initial cell population.
Association between Immunosuppressive Therapy Utilized in the Treatment of Autoimmune Disease or Transplant and Cancer Progression

Autoimmunity and cancer rates have both been on the rise in Western civilization prompting many to investigate the link between the two entities. This review will investigate the complex interactions between the activation and deactivation of the immune system and the development of malignancy. Additional focus will be placed on the main classes of immune inhibitor therapy utilized in transplant patients and in autoimmune disease including TNF-alpha, Calcineurin, mTOR, purine synthesis antagonists and IMPDH inhibitors.
Communities of Inquiry and the Case of the "Distance Education" Group during the COVID-19 Pandemic

According to the Community of Inquiry (CoI) Framework, successful learning experiences are supported by the presence and interaction of cognitive, social, and teaching elements. Since the CoI Framework has been widely used to examine the quality of educational interactions, its applicability to non-formal education has not been adequately explored. This research is a case study of the "Distance Education" group on Facebook. It was mainly carried out during a period of restrictions due to COVID-19, when most schools in Greece remained closed. This study explores the process by which shared understanding and learning were fostered in a Peer-to-Peer setting of teachers. Through group exploration and interaction team members were able to provide solutions and answers while focused discussion and smooth functioning were controlled by administrators who were also educators. The results of this research show the presence of social, cognitive, and teaching elements during the discussions. Similarly, the findings of the analysis of the discussions show that they contained content directly related to the learning activities, thus indicating the presence of the cognitive component. Off-topic discussions helped develop social relationships. Overall, when interpreted within the framework of CoI, the results reveal that all three components of an effective online learning experience were present in the context of Peer-to-Peer conversations between teachers. The most important finding is that during the pandemic, teachers had to develop reciprocal relationships and create common plans and projects that helped them overcome difficulties and, finally, reflect dialectically on the extraordinary conditions created by the pandemic. The results of the research can be used by professionals who wish to apply the framework in a non-formal educational setting.
An integral equation approach to internal (2-layer) solitary waves

The exact within potential flow integral equation approach of Evans and Ford [Proc. R. Soc. London Ser. A 452, 373 (1996)] for the normal solitary wave, is here generalized to 2‐layer, ‘‘internal’’ solitary waves. This differs in its mathematical form from other exact integral equation methods based on the complex velocity potential. For both ‘‘rigid lid’’ (i.e., flat toplayer surface) and ‘‘free‐surface’’ boundary conditions, a set of coupled non‐linear integral equations are derived by an application of Green’s theorem. For each point on the layer interface(s), these describe functional constraints on the profiles and interface fluid velocity moduli; the exact profiles and velocities being those forms that satisfy these constraints at all such interface points. Using suitable parametric representations of the profiles and interface velocity moduli as functions of horizontal distance, x, and utilizing tailored quadrature methods [Int. J. Comput. Math. B 6, 219 (1977)], numerical solutions were obtained b.
The analysis of apparent optical depth profiles for interstellar absorption lines

Attention is given to the apparent optical depth method, a procedure for analyzing interstellar absorption lines. Observed absorption-line profiles are converted into profiles of apparent optical depth, and apparent column density per unit velocity. By comparing the latter for a given interstellar species having two or more absorption lines which differ in the product, the presence or absence of unresolved saturated structure in the profiles can be directly inferred. The method is illustrated using absorption-line data from the IUE satellite for the highly ionized gas toward HD 64760. Additional illustrations and a study of the method's accuracy are provided through a series of numerical simulations of multicomponent interstellar absorption situations. The method is compared to the standard growth curve method for deriving interstellar column densities. The principal value of the apparent optical depth method is that the absorption-line data are directly converted into a form that provides for direct scientific interpretations of the physical conditions in the interstellar absorbing medium as a function of velocity.
KPC-Producing Enterobacterales from Douro River, Portugal—Persistent Environmental Contamination by Putative Healthcare Settings

Carbapenemase-producing Enterobacterales (CPE) are a growing concern, representing a major public health threat to humans, especially in healthcare settings. In the present study, we evaluated the persistent contamination by carbapenem-resistant Enterobacterales in water from Douro River, Portugal. KPC-producing Enterobacterales were detected in five water samples separated chronologically by 15 days each. Susceptibility testing was performed by disk-diffusion-method according to Clinical and Laboratory Standards Institute (CLSI), phenotypic carbapenemase activity was evaluated by carbapenem inactivation method, presumptive identification of the isolates was performed by CHROMagar orientation and confirmed by API-20E. Carbapenemase genes were screened by PCR and the clonality of all isolates was assessed by XbaI-Pulsed Field Gel Electrophoresis (PFGE). Fifteen KPC-producing Enterobacterales isolates were selected, identified as multidrug-resistant and showed a resistance profile to non-beta-lactam antibiotics: sulfamethoxazole + trimethoprim (7/15), ciprofloxacin (3/15), fosfomycin (3/15) and chloramphenicol (2/15). Isolates were identified as (6) Escherichia coli and (9) Klebsiella pneumoniae. Our results suggest a punctual contamination with KPC-producing Enterobacterales continued through the time. The absence of clonality between the isolates suggests a circulation of mobile genetic element harbouring KPC gene in the origin of contamination. This work provides a better understanding on the impacts of water pollution resulting from human activities on aquatic environments.
Phytase Supplementation under Commercially Intensive Rearing Conditions: Impacts on Nile Tilapia Growth Performance and Nutrient Digestibility

Simple Summary Fish farming is a fast-growing feed production sector that is expected to significantly contribute to world food safety. The awareness of the environmental impacts of this activity is increasing, as are the practices to enhance fish farming sustainability. Phytase is a feed additive that improves not only fish growth performance but also fish farming sustainability by reducing nutrient discharge in the water. In this regard, we evaluated phytase effects on nutrient digestibility and growth performance of Nile tilapia under commercially intensive rearing conditions. The results of this study demonstrate that phytase can be used as an approach to minimize fish farming environmental impacts and boost fish growth. Besides that, our results validate the findings of previous studies conducted under controlled laboratory conditions. Abstract This study evaluated the effects of phytase supplementation on growth performance and apparent digestibility of Nile tilapia (Oreochromis niloticus) in a commercial fish farm setting. Nile tilapia (6300 male, 57.48 ± 1.04 g) were randomly stocked into 42 floating cages. The experimental design was completely randomized, comprising six treatments and seven replications. Fish were fed five phosphorus deficient plant-based diets with graded levels of phytase supplementation (0, 500, 1000, 1500, 2000 UF kg−1) and an additional diet containing phosphorus supplementation to meet the requirement of this fish species (positive control). After 97 days of feeding, growth performance data were collected and 900 fish (500 ± 10 g) were relocated to 6 floating cages for the digestibility assessment. Quadratic polynomial regression analysis indicated 1537.5 and 1593.2 UF kg−1 as the optimum dietary levels for daily weight gain and feed conversion rate, respectively. Including 2000 UF kg−1 resulted in the higher dry matter, crude protein, energy, and ash apparent digestibility coefficient values. Therefore, phytase supplementation from 1500 to 2000 UF kg−1 is recommended to enhance growth performance and nutrient bioavailability of Nile tilapia reared according to industry practices.
Self-similar low-noise femtosecond ytterbium-doped double-clad fiber laser

We report the generation of self-similar highly stable femtosecond pulses from an ytterbium-doped double-clad fiber laser. Positively chirped parabolic pulses with 6.4-ps duration and more than 3.2-nJ energy are obtained. These pulses are extra-cavity compressed to 140 fs. Radio-frequency noise measurements show that this regime of emission ensures low-noise operation with less than 0.05% amplitude fluctuations.
On the Internal Stability of Explicit, m‐Stage Runge‐Kutta Methods for Large m‐Values

Explicit, m-stage Runge-Kutta methods are derived for which the maximal stable integration step per right hand side evaluation is proportional to m when applied to semi-discrete parabolic initial-boundary value problems. The internal stability behaviour of these methods is compared with that of similar Runge-Kutta methods proposed in the literature. Both by analysis and by numerical experiments we show that the value of m in the schemes proposed in this paper is not restricted by internal instabilities.
TOURIST SATISFACTION DURING THE PANDEMIC: AN ANALYSIS OF THE EFFECTS OF MEASURES TO PREVENT COVID-19 IN A MEDITERRANEAN COASTAL DESTINATION

The impact of the COVID-19 on tourist satisfaction is a particular relevant issue, due to the role that elements such as the prevention measures implemented at the destination might play. For this reason, this article examines tourist satisfaction during the peak tourist season of 2020 in a mature coastal destination in Catalonia in relation to safety and prevention measures imposed due to the COVID-19 pandemic. We use explanatory factor analysis and partial least squares path modelling for comparing the determinants of tourist satisfaction prior and during the pandemic based on surveys conducted in 2019 (N = 1556) and 2020 (N = 2220). The results suggest that the determinants of overall tourist satisfaction in 2019 remained significant in 2020. Moreover, although tourists especially appreciated feeling safe in 2020, our results suggest that such a perception was unrelated to measures to prevent COVID-19. The paper raises concerns towards the management of situations such as the pandemic in tourist destinations, as a proper balance must be found between the need of making visitors feel safe, and avoiding measures that can be felt as invasive or annoying, hampering the tourist experience.
Use of WeChat to gratify information needs of the Chinese community in Portugal during the COVID-19 outbreak

[Objectives] This paper seeks to characterize the main themes of COVID-19-related posts delivered by WeChat official accounts targeting Portuguese news, and explore the information needs and preferences of their users. Furthermore, the current study set out to evaluate the influence of coronavirus situation in Portugal on the number of posts, view frequency and total engagement on WeChat platforms. [Methods] Following the selection of COVID-19-related posts published in 2021 by four official accounts targeting Portuguese news, Chi-square tests were conducted to quantitively describe the differences between the four developmental stages of the COVID-19 pandemic in Portugal. Negative binominal regression was employed to establish an association between category variables and count data. Regression analysis was used to explore the relationship between COVID-19 infection cases in Portugal and the metrics of selected posts. [Results] A total of 3292 COVID-19-related posts remained. The posts regarding the latest epidemic situation in Portugal, COVID-19 vaccination and the economic news were more prevalent. However, the predominant posts were not consistent with followers’ information demands, and the most in demand information did not generate more engagement. In addition, thematic categories were found to be significantly associated with view frequency and total engagement. Furthermore, a significant difference in thematic categories was identified among the four developmental stages, which in turn was found to be related to the overall engagement of posts. The COVID-19 official case counts in Portugal is predictive of post frequency, view frequency and total engagement. [Conclusions] The results of this study support the view that social media provided diverse information sources for migrants during the ongoing COVID-19 pandemic. However, it is evidently clear from the findings that communicators have to leverage the characteristics of social media, not only for delivering real-time news, but also to gratify public information needs and attract more users.
On the Radial Vibration of Ball Bearings : Computer Simulation

Computer simulation is used to analyze the radial vibration of ball bearings in order to overcome the experimental and theoretical difficulties : the experimental difficulties are due to the complicated interaction of the dominant factors while the theoretical difficulties are due to the nonlinear spring behaviour and time-dependent excitation of ball bearings. The inner ring motion, which involves the Perret-Meldau problem, is considered in the radial plane for an ideal bearing the massive inner ring of which rotates at a constant speed under a constant radial load. The results show that superharmonic, subharmonic, beat and chaos-like vibrations appear, in addition to harmonic vibration which synchronizes with ball passage.
Biofertilizer reduces the dependency on chemical fertilizer on wheat production

Scarce availability of chemical fertilizers threatens sustainability of wheat production in Nepal. Combined application of chemical and biofertilizer can reduce chemical fertilizer and enhance the yield under limited fertilizer availability. A field experiment was carried out to assess the combined application of chemical and biofertilizer on the growth and yield of spring wheat at Rampur, Chitwan from November 2020 to April 2021. The experiment was laid out in strip plot design with four nitrogen and P2O5 levels (0, 50, 75 and 100% of recommended dose) in vertical plots and three biofertilizer application methods (not applied, seed applied and soil applied) in horizontal plots with three replications. The research results revealed significant interaction between nitrogen and P2O­5 levels and biofertilizer application methods. The highest grain yield (4624.48 kg ha-1) of wheat was obtained with 100% levels of N and P­­­2O5 with soil applied biofertilizer at par with 75% levels of N and P­­­2O5 with soil applied biofertilizer (4457.54 kg ha-1). The total nitrogen uptake was higher in biofertilizer applied wheat as compared with no application of biofertilizer although statistically not significant. The yield increment in 100% and 75% N and P­­­2O5 levels with soil applied biofertilizer over same level N and P­­­2O5 with no biofertilizer application were 10.96% and 29.60% respectively. The higher gross return, net return and B:C ratio were obtained with 75% and 100% N and P2O5 levels with soil and seed applied biofertilizers. The result indicates that 25% recommended dose of N and P2O5 could be reduced by soil application of biofertilizer without compromising the grain yield of wheat. Int. J. Appl. Sci. Biotechnol. Vol 10(4): 245-253.
Power Losses of Ni-Substituted Mn–Zn Ferrites

Effects of Ni-substitution in Mn–Zn ferrites on power losses and electromagnetic properties have been studied. When NiO was substituted for MnO in the range from 0 to 8 mol%, lattice constants decreased gradually due to the smaller ionic radius of Ni ions. NiO substitution lowered the initial permeability and increased the Curie temperature. NiO substitution also suppressed the magnitude of the imaginary part of complex permeability in the high-frequency range (>1 MHz). The minimum power loss at 1 MHz and 25 mT moved to higher temperatures with NiO substitution. The sample with 4 mol% NiO showed the lowest power loss of 57 kW/m3 at 80°C, 1 MHz and 25 mT.
Linear approximant-based metaheuristic proportional-integral-derivative controller for a neutral time delay central heating system

Abstract For a test-case central heating plant, modelled as a non-linear neutral time delay system, a metaheuristic proportional-integral-derivative (PID) control scheme is proposed to control the temperature of the room using as a sole actuatable input the energy supplied to the boiler. The control scheme is based on a neutral time delay description of the linearized approximation of the process. The linearization is tested using a Euclidian norm type of error, with emphasis on the performance variable of the system, to show that it is an accurate approximation of the original process for a wide range of variables of the plant. The performance of the closed-loop system is examined via simulation experiments.
The Soft Coral Sarcophyton trocheliophorum: A Warehouse of Terpenoids with Structural and Pharmacological Diversity

The soft coral Sarcophyton trocheliophorum, which was frequently encountered on Indo-Pacific and Red Sea coral reefs, furnished a wealth of secondary metabolites. Notably, terpenoids dominated the chemical profile of this species. In this review, we summarized the discovery of 156 terpenoids from the soft coral S. trocheliophorum specimens in different geographical areas. The structures comprised 13 terpenoidal classes with various functionalities. We covered the era from the first report of S. trocheliophorum-derived metabolites in 1976 up to October 2022. The biological effects of these chemical compositions on a vast array of potential pharmacological activities such as protein tyrosine phosphatase 1B (PTP1B) inhibitory, neuroprotective, cytotoxic, anti-inflammatory, antibacterial, antivirus, and immunomodulatory activities were also presented. This review also revealed an immense demand to explore the terpene biosynthetic gene clusters of this species besides the chemo- and bio-investigations.
