Market turbulence and service innovation in hospitality: examining the underlying mechanisms of employee and organizational resilience

ABSTRACT With changing customer demand, fierce market competition, and uncertainties, service organizations are facing dynamic or even highly turbulent environments. Fostering employees’ ability to innovate is an effective business strategy that can enable firms to overcome market turbulence and cope with these challenges. Drawing on resilience theory, this study examines (1) the mediating effect of employee resilience on the relationship between market turbulence and service innovation, and (2) whether such mediating process was moderated by organizational readiness for change. Data were collected from employees in the hospitality industry in a developing country, Ethiopia, and the results indicated that employee resilience partially mediates the relationship between market turbulence and service innovation. Moreover, the indirect link was stronger for hotels with higher readiness for change than for those with lower readiness for change. Implications for managers and directions for further research are also discussed.
Identification of Multiple Noise Sources Improves Estimation of Neural Responses across Stimulus Conditions

Abstract Most models of neural responses are constructed to reproduce the average response to inputs but lack the flexibility to capture observed variability in responses. The origins and structure of this variability have significant implications for how information is encoded and processed in the nervous system, both by limiting information that can be conveyed and by determining processing strategies that are favorable for minimizing its negative effects. Here, we present a new modeling framework that incorporates multiple sources of noise to better capture observed features of neural response variability across stimulus conditions. We apply this model to retinal ganglion cells at two different ambient light levels and demonstrate that it captures the full distribution of responses. Further, the model reveals light level-dependent changes that could not be seen with previous models, showing both large changes in rectification of nonlinear circuit elements and systematic differences in the contributions of different noise sources under different conditions.
Growth and influence of a porous iron oxide nanolayer on LiMn2O4 in an aqueous rechargeable lithium‐ion battery

A porous iron oxide nanolayer coating is grown on LiMn2O4 by a facile in‐situ method. Evolution of this coating and its influence on the structural retention and electrochemical activity of LiMn2O4 is examined and compared to a control in the environment of an aqueous rechargeable lithium‐ion battery. Two coinciding mechanisms of porous iron oxide nanolayer deposition and their depency on electrolyte pH are identified and discussed. The coating is found to significantly reduce Li2MnO3 surface formation, a major source of capacity fade in LiMn2O4 electrodes, thereby improving the structural retention. The nanolayer was also found to improve the electrochemical stability of the underlying LiMn2O4 in the potential window of lithium intercalation, reduce the growth rate of mass transfer and solid electrolyte interface resistances over the control, while also providing reduced charge transfer resistances over the pristine LiMn2O4 material. The totality of these improvements provided by the porous iron oxide nanolayer preserved the electrochemical and structural integrity of LiMn2O4 over the course of 500 deep discharge cycles in aqueous media.
Study on the satellite based assessment of malaria mosquitogenic conditions in and around Dehradun

The relevant satellite data after procuring from National Remote Sensing Agency (NRSA) was analysed using ERDAS Imagine version 8.6 and IDRISI version 2. Based on supervised classification and land use patterns, the mosquitogenic conditions have been verified in the study area by using satellite imagery (PAN, LISS-III and WIFS) as well as by paying a visit to the field. On the basis of mosquito breeding in various habitats, it concludes that the river beds, rain water collection, pools, flooded agricultural fields, canals, ponds, marshy areas have been found to be the potent breeding habitats of mosquitoes. The survey work conducted during the year 2004 and 2005 reveals occurrence of 15 species of Anopheles (An. aconitus, An. annularis, An. culicifacies, An. fluviatilis, An. gigas, An. jeyporiensis, An. lindesayi, An. maculatus, An. nigerrimus, An. splendidus, An. stephensi, An. subpictus, An. theobaldi, An. vagus and An. varuna), besides Aedes sp. , Culex sp. , Armigeres sp. and Uranotaenia sp. in three study belts namely, Kalsi-Vikasnagar, Sahaspur-Selaqui and Raipur-Doiwala belt in district Dehradun. Considering, the population of Anophelines as harboured in all the three different belts, it was maximum at RaipurDoiwala belt followed by Sahaspur-Selaqui and Kalsi-Vikasnagar belts in succession. At KalsiVikasnagar and Raipur-Doiwala belt, 12 species of Anopheles were found as adults. However, the immature density was recorded more in Kalsi-Vikasnagar belt (11) than Raipur-Doiwala belt (9). In Sahaspur-Selaqui belt, 11 species of adult Anopheles and only 9 species of immature forms were recorded.
Attachment of peri-implant pathogens to laser melted abutments and the development of a novel antimicrobial coating.

Dental implant placement is undertaken increasingly frequently to restore the function and aesthetics of missing teeth. The abutment forms the interface between the implant and overlying crown, bridge or denture prosthesis. Despite reasonable long‐term survival of dental implants overall, inflammation of peri-implant tissues may develop in response to chronic insult from microbial biofilms formed on implant surfaces, leading to implant failure. Despite efforts in developing novel treatments, progression and recurrence of peri-implantitis is a major clinical problem. Therefore, focus on prevention rather than treatment of peri-implant conditions is crucial. This project aimed to investigate the early, direct attachment of peri-implant pathogens Fusobacterium nucleatum (FN) and Porphyromonas gingivalis (PG) to laser melted Ti6Al4V. Subsequently, a novel antimicrobial abutment coating was developed to reduce bacterial attachment. Both microbes attached readily to Ti6Al4V without the aid of early colonisers in the presence and absence of artificial saliva (AS). Interestingly, AS reduced FN attachment and encouraged the attachment of the more pathogenic PG to laser melted surface. The developed antimicrobial coating was composed of triclosan-loaded liposomes, tethered to the Ti6Al4V oxide layer by the amphiphilic molecule octadecylphosphonic acid. Liposomes were composed of phosphatidylcholine and cholesterol at a 7:1 w/w ratio and encapsulated 300 μg/mL triclosan in 3 mg/mL lipids. Triclosan demonstrated efficacy in inhibiting both FN and PG. The liposomes were successfully adsorbed to the laser melted surfaces, although this coating was not uniform. The triclosan-loaded liposomal coating showed high antimicrobial efficacy against FN and PG in the absence of AS. However, preconditioning of coated surfaces with AS reduced liposomal antimicrobial activity. This work indicates that bacterial attachment to oral metallic implants may differ from the successive process described in the literature. A novel liposomal coating demonstrated potential in preventing attachment and proliferation of clinically relevant implant pathogens which may reduce peri-implantitis risk.
Impact of Electronic Health Record Interface Design on Unsafe Prescribing of Ciclosporin, Tacrolimus, and Diltiazem: Cohort Study in English National Health Service Primary Care

Background In England, national safety guidance recommends that ciclosporin, tacrolimus, and diltiazem are prescribed by brand name due to their narrow therapeutic windows and, in the case of tacrolimus, to reduce the chance of organ transplantation rejection. Various small studies have shown that changes to electronic health record (EHR) system interfaces can affect prescribing choices. Objective Our objectives were to assess variation by EHR systems in breach of safety guidance around prescribing of ciclosporin, tacrolimus, and diltiazem, and to conduct user-interface research into the causes of such breaches. Methods We carried out a retrospective cohort study using prescribing data in English primary care. Participants were English general practices and their respective EHR systems. The main outcome measures were (1) the variation in ratio of safety breaches to adherent prescribing in all practices and (2) the description of observations of EHR system usage. Results A total of 2,575,411 prescriptions were issued in 2018 for ciclosporin, tacrolimus, and diltiazem (over 60 mg); of these, 316,119 prescriptions breached NHS guidance (12.27%). Breaches were most common among users of the EMIS EHR system (breaches in 18.81% of ciclosporin and tacrolimus prescriptions and in 17.99% of diltiazem prescriptions), but breaches were observed in all EHR systems. Conclusions Design choices in EHR systems strongly influence safe prescribing of ciclosporin, tacrolimus, and diltiazem, and breaches are prevalent in general practices in England. We recommend that all EHR vendors review their systems to increase safe prescribing of these medicines in line with national guidance. Almost all clinical practice is now mediated through an EHR system; further quantitative research into the effect of EHR system design on clinical practice is long overdue.
Market town household solid waste management: a case study of Embu, Kenya

Household solid waste management directly impacts human health and the environment. Globally, increasing quantities and complexity of household solid waste has become a menace in many market towns. The aim of this study was to establish the status of household solid waste management in the market town of Embu in Kenya. The objectives were to identify the methods used by households to manage solid waste and to establish the factors that influenced the households’ choice of solid waste management method. A survey design was deployed and questionnaires were used in data collection. Data analysis was done using the Statistical Package for Social Sciences software. 37% of the households discarded their solid waste in open places, 32% burnt and 24% recycled it. About 8% households reused the solid waste. Employment, education and access to waste collection services were the major factors influencing household solid waste management strategy. Sustainability of household solid waste management depended on awareness on health and environmental benefits of improved household solid waste management, reduction in household solid waste generation and establishment of a household solid waste management policy for Embu market Town. It was concluded that the current practices for household solid waste management are inadequate. High level of unemployment and low education level hinder proper household solid waste management. Awareness on the health and environmental benefits and policy could improve household waste management in the market town. Keywords: Recycling, Solid waste, Environmental impact, Sustainability
The effect of social contexts and formation of individualism-collectivism orientation on knowledge sharing intention: the case of workers in Korea

This study aims to pay attention to the role of social contexts, including perceived relationship conflict and coworker support in creating an individualistic or collectivistic disposition, and how organization members differently behave to share knowledge depending on their personal dispositions. ,The research model was set and PLS-SEM was used to validate the proposed eight hypotheses. A total of 462 survey data were collected from workers in Korea to test the model. ,The findings revealed that both perceived relationship conflict and coworker support positively influence knowledge sharing intention by facilitating formation of individualism and collectivism orientation. In other words, individualism and collectivism are motivated by different factors, which applies equally to knowledge sharing. ,This study makes an initial step to explain the relationship between knowledge sharing behavior and individualism–collectivism orientation by using social contexts as a potential antecedent. Especially, along with perceived co-worker support, perceived relationship conflict was also found to have a positive impact on knowledge sharing intention through individualism orientation, which is a significant contribution to the field of knowledge management.
Miniaturized dual‐band slot antenna design for GPS, amateur radio and WLAN applications

In this article, miniaturization of dual‐band slot antenna design for GPS, WLAN and amateur radio applications is presented. The proposed dual‐band miniaturized antenna is achieved using slits, rectangular split ring and metallic strips fed by 50 Ω microstrip feed. The first resonant frequency is achieved by loading reference antenna with eight slits that is antenna 1 and the second resonant frequency is achieved by loading with one center slits and rectangular split ring that is antenna 2. Dual‐band antenna is achieved by loading reference slot antenna with nine slits and rectangular split ring which resonates at frequency of 1.52 and 3.03 GHz respectively. As a result, it is achieved 53.79% reduction in first band resonant frequency with 76.07% improvement in −10 dB bandwidth and 7.90% reduction in second band resonant frequency compared to reference slot antenna. Further, this dual‐band antenna is miniaturized by metallic strips which are placed on the bottom of the substrate. This results in 61.39% reduction in first band resonant frequency with 32.07% improvement in −10 dB bandwidth and 26.13% reduction in second band resonant frequency in comparison with reference slot antenna topology.
Mutation and expression of the C-KIT gene on population of Kazakhstan

Lung cancer is still a leading cause of death from malignant tumors worldwide. Due to late diagnosis, results of treatment remain unsatisfactory. In Kazakhstan about 3,669 new cases of lung cancer are detected every year, with a 5-year survival rate for 2016 equal to 48.0%. The aim of the current work is to study the expression of C-KIT protein and identify mutations in patients with lung cancer living in Almaty region. Literature data showed that anomalous expression of the corresponding gene and presence of mutations lead to a number of malignant neoplasms. Creation of drugs targeting C-KIT protein, promotes the development of clinical diagnosis and treatment of cancer. Blood samples and biopsy material obtained from patients diagnosed with lung cancer, treated at the Almaty Oncology Center and residing in Almaty region served the objects of the study. Written informed consent was obtained from all patients. Analysis of restriction fragment length polymorphism and immunohistochemical analysis followed the polymerase chain reaction. For immunohistochemical analysis tissue fixed in formalin and embedded in paraffin blocks was used. The presence of mutations in codon 557 was revealed by the genetic analysis of 11 exon of C-KIT gene. RFLP analysis and sequencing showed mutations in the codon. Immunohistochemical analysis revealed overexpression of C-KIT gene in four (9.09%) patients, 14 (31.82%) patients had moderate expression, 24 (54.54%) patients had weak expression and two (4.55%) patients had no expression. In total, 18 (40.91%) patients had a positive response to immunohistochemical analysis. This suggests that the disorders occur in the cells of tumor tissue and are not inherited. In fact, in most cases the occurrence of lung cancer can be associated with smoking.

Non-steroidal immunosuppressive drugs for non-neoplastic ocular disorders

Introduction Immunomodulatory or immunosuppressive drugs have an ability to suppress the immune drive by producing certain soluble bioactive molecules like cytokines and chemokines thus decreasing the tissue damage resulting from the inflammatory mediators. The use of immunosuppressives in ophthalmology follow their extensive use as anticancer chemotherapeutic agents. Nonneoplastic use of immunosuppressive agents by ophthalmologists has greatly increased over the past three decades because of better knowledge of the immunopathology of immune mediated, noninfectious ocular inflammatory disorders, affecting conjunctiva, cornea, sclera, uveal tissue etc. Most of the uveal disorders such as non-infectious uveitis associated with arthritis and collagen vascular diseases e.g. Vogt-koyanagi-Haradas disease, Behecets disease, sympathetic ophthalmitis, pars planitis etc are immune mediated and require immunosuppressive agents if corticosteroids fail or are not tolerated or contraindicated. Allergic eye diseases like vernal keratoconjunctivitis and atopic keratoconjunctivitis are characterized by complex immunopathology. Immunomodulating agents like cyclosporine A and tacrolimus can be used to inhibit T-cell activation among the patients with severe allergic eye diseases. Other immune mediated ocular conditions which require immunosuppressive drugs are thyroid associated ophthalmopathy (TAO), dry eye disease, necrotizing scleritis, moorener’s ulcer, limbal cell transplantation and peripheral ulcerative keratitis (PUK). Earlier, the use of immunosuppressives were limited to treatment of corticosteroid resistant, sight threatening ocular inflammation , but now a days these drugs are considered as first line of treatment for Wegeners granulomatosis, Behcetss disease etc. Most of the immunosuppressive agents are extremely potent and have significant adverse effects. The purpose of this review is to briefly summarize the management of various ocular inflammatory disorders by using immunosuppressive agents, with focus on use of newer immunosuppressive drugs. A review of the literature in the PubMed, MedLine, and Cochrane database was conducted to identify clinical trials, comparative studies, case series and case reports describing the use of immunosuppressive therapy.

Fuzzy Adaptive Finite-Time Fault-Tolerant Control for Strict-Feedback Nonlinear Systems

This article devotes to investigating the issue of fuzzy adaptive control for a class of strict-feedback nonlinear systems with nonaffine nonlinear faults. The computational complexity is reduced by adopting the dynamic surface control technique. Under the framework of finite-time stability, a novel fault-tolerant control strategy is designed so that the closed-loop system is semiglobally practically finite-time stable, and the tracking error converges to a small residual set in a finite time. Finally, simulation studies for an electromechanical system are shown to verify the feasibility of the presented approach.
Aggregate Volatility Risk: International Evidence

Abstract Using a procedure analogous to that of Ang et al. (2006), this paper documents that aggregate volatility risk does not appear to be priced in European equity markets. Specifically, based on the 2002–2016 period (for which European stock return data is available), the price of aggregate volatility risk is not statistically different from zero. Analysis based on GARCH-class and high-frequency intraday data models support these results. Consequently, contrary to what has been reported in some studies that examine U.S. data, whether aggregate volatility risk is priced in equity markets is an open question.
