Professional quality of life and resilience in emergency department healthcare professionals during COVID-19 in Hong Kong: A cross-sectional study

Background: The professional quality of life of healthcare professionals in emergency departments may be compromised during the COVID-19 pandemic. Objectives: This study aims to examine professional quality of life and resilience as well as their relationships among emergency department healthcare professionals in Hong Kong during the COVID-19 outbreak. Methods: This study employed a cross-sectional design. Healthcare professionals (doctors and nurses) working in emergency departments in Hong Kong were recruited via snowball sampling. The Professional Quality of Life Scale, version 5, and the 10-item Connor-Davidson Resilience Scale were used to assess their positive (compassion satisfaction) and negative (secondary traumatic stress and burnout) aspects of professional quality of life and self-reported resilience. Socio-demographics and work-related characteristics were also analysed. Results: A total of 106 participants provided valid responses. The results showed an overall moderate level of compassion satisfaction, secondary traumatic stress and burnout among emergency department healthcare professionals. The mean score of the 10-item Connor-Davidson Resilience Scale was 23.8. Backward linear regression analyses revealed self-reported resilience was the only significant predictor of compassion satisfaction (regression coefficient B = 0.875; p < 0.001), secondary traumatic stress (B = −0.294, p < 0.001) and burnout (B = −0.670; p < 0.001), explaining 70.6%, 18.5% and 59.8% of total variance, respectively. Conclusion: Emergency department healthcare professionals in Hong Kong experienced an overall moderate level of professional quality of life during the COVID-19 outbreak. Those with a higher level of self-reported resilience had better compassion satisfaction and lower levels of secondary traumatic stress and burnout. The results support the importance of developing interventions that foster resilience among this group of emergency department healthcare professionals to combat COVID-19.
Prognostic Role of Porphyromonas Gingivalis in Oral Cavity Squamous Cell Carcinoma Patients

Background: Oral microbial species play direct and/or indirect role in carcinogenesis of oral cavity squamous cell carcinoma (OSCC). Porphyromonas gingivalis (Pg) has been identified a correlation with OSCC. Fimbriae play a vital role for its attribution of initial attachment and adhesion of Pg. Six genotypes (types I-V, Ib) of fimA were identified based on sequence variations and the genotype was suggested a relationship to pathogenicity of Pg.Objective: To investigate the abundance of Pg in OSCC as well as the frequency of Pg fimA genotypes in OSCC patients.Methods: Ninety-five OSCC patients and thirty-nine gender- and age-matched non-OSCC subjects were investigated abundance of Pg in saliva. Presence of Pg was compared in OSCC tissue and para-cancerous tissue from patient as well. Clinical data were extracted and patients followed up for a mean period of 13 months. Presence of Pg and fimA genotypes were investigated in OSCC tissue and in saliva, then PCR products were sequencing and compared.Results: OSCC patients showed high abundance of Pg in saliva (Chi-square=14.531, P=0.001). OSCC tissue showed strong in situ expression of Pg by in situ hybridization compared with normal tissue adjacent to OSCC. Patients with overabundance of Pg in saliva are associated with systemic disease (Chi-square=10.328, P=0.029), longer disease-free time (Z=-2.988, P=0.003), and lower recurrence rate (Chi-square=5.670, P=0.017). The abundance of Pg was an independent favorable prognostic factor (HR: 0.124, 95%CI: 0.016 to 0.941). There was dominant distribution of Pg with genotype I+Ib (21.1%), II (31.6%) and IV (21.1%) in OSCC patients. The fimA genotypes detected in saliva were in accordance with those in OSCC tissue, and there was significantly correlation in amplified Pg fragments similarity between in saliva and in OSCC tissue. Conclusions: This study indicated that Pg might involve in the pathogenesis of OSCC, and Pg might consider as a potential prognostic indicator in OSCC. There was a dominant distribution of Pg with genotypes I, Ib, II and IV in OSCC patients. The presence of Pg in tumor might be saliva in provenance.

A Least Squares Regression Realized Covariation Estimation

We propose a least squares regression framework for the estimation of the realized covariation matrix using high frequency data. The new estimator is robust to market microstructure noise (MMS) and non-synchronous trading. Comprehensive simulation and empirical analysis show that our estimator performs as well as a set of popular estimators in the literature. More importantly, our framework allows for the unique identification of MMS noise moments. We find that these noise moments are related to measures of liquidity and contain predictive information that helps to significantly improve out-of-sample asset allocation.
The Evolution of Cable Network Branding: Time Warner in the Post-Network Era, 2001-2011

From 2001 to 2011, there were a number of significant changes, such as increased audience fragmentation and new media technologies, which impacted the television industry and continue to threaten the financial strength and success of cable television networks. The cable television industry employed branding as a major combatant to manage such challenges. Branding is the most important tool in the post-network era, yet networks use it in ways that challenge previously held scholarly assumptions about the cable television industry. Cable television network branding functions in two main ways – one as a performance intended for competitors, distributors, and other key industry players; and two as a means of rationalization, essentially a tool that network executives can wield whenever they want or need to justify a decision, action or behavior.

Online Retail Store Community Engagement and Its Impact on Purchase Intentions in the Context of Online Reviews

Consumers want to engage with the retail store community in the shopping context. This study examines how consumers’ perceptions of source credibility and perceived usefulness of online reviews impact an intention to engage with the online retail store community and purchase intentions. The study also identifies differences when reviews are posted by customers versus store employees. Results show that the proposed relationships within the structural model are significant and reviews posted by store employees are seen as more credible, whereas reviews posted by other customers are perceived to be more useful. Theoretical and managerial implications are discussed.
ALLEVIATION OF WATER DEFICIENCY EFFECT BY APPLICATION OF POTASSIUM SILICATE TO FABA BEAN INTERCROPPED WITH SUGAR BEET IN SANDY SOIL

Two field experiments were carried out at Ismailia Agricultural Research Station, Agricultural Research Center, Ismailia governorate (Lat. 30° 35' 30" N, Long. 32° 14' 50" E, 10 m a.s.l.), Egypt, during 2018/2019 and 2019/2020 growing seasons. The objective of this study was to determine the rate of potassium silicate that could mitigate the effect of water shortage on productivity of faba bean intercropped with sugar beet and its effects on water and land equivalent ratios, as well as farmer’s net revenue. In split plot design with three replications, three irrigation treatments i.e., 120, 100 and 85% Evapotranspiration (mm/d) (ETo) were assigned to the main plots, while three rates of sprayed potassium silicate (unsprayed (control), 200 ppm and 300 ppm) were arranged in sub-plots. The results showed that irrigation with 120% ETo and spraying with 200 ppm potassium silicate attained the highest yield and its components for both faba bean and sugar beet under their intercropping system in both growing seasons. For faba been and sugar beet, N, K and Si content were positively affected by irrigation levels at 100% ETo with foliar potassium silicate 200 ppm, but P content was positively affected by irrigation levels at 120% ETo with foliar 200 ppm potassium silicate. The available P and K in the soil were positively affected by irrigation with 120% ETo with foliar 300 ppm potassium silicate. N content was positive affected by irrigation with 100% ETo with foliar 200 ppm potassium silicate. The highest values of water and land equivalent ratios (WER and LER), as well as total and net return were obtained under irrigation with 120% ETo and spraying with 200 ppm potassium silicate. However, both WER and LER under application of 100% ETo and 200 potassium silicate were higher than irrigation with120% ETo and unsprayed plants in both growing seasons. The highest value of farmer net revenue was obtained when 120% ETo and spraying with 200 ppm potassium silicate were applied. Thus, to attain the highest faba bean with sugar beet in an intercropping system and highest water and land equivalent ratios, as well as farmer’s net revenue, 120% ETo and spraying with 200 ppm potassium silicate should be applied. However, in case of water shortage, 100% ETo and spraying with 200 ppm potassium silicate could be applied to mitigate the effect of water deficiency.
Relationship of Metabolic Syndrome Defined by IDF or Revised NCEP with Glycemic Control among Malaysians with Type 2 Diabetes

Background Chronic complication of Type 2 Diabetes (T2D) such as macrovascular disease is amplified with the increase in the number of the metabolic syndrome (MetS) risk factors. Specific criteria for diagnosis of MetS are essential to help in glycemic control and reduce cardiovascular morbidity and mortality in diabetic patients with metabolic syndrome.Methods The study is cross-sectional observational study which involved 485 T2D patients who are receiving treatment at the University Kebangsaan Malaysia Medical Center (UKMMC), Kuala Lumpur, Malaysia. Metabolic syndrome among the T2D patients was diagnosed based on IDF and NCEP-R criteria. C-peptide and glycated hemoglobin (HbA1c) levels were determined by an automated quantitative immunoassay analyzer and high-performance liquid chromatography, respectively. The metabolic syndrome factors, glucose, triglyceride and HDL cholesterol were measured by spectrophotometer Results Application of IDF and NCEP-R criteria respectively resulted in 73% and 85% of T2D subjects being diagnosed with MetS. The concordance of these criteria in diagnosing MetS among T2D was low (κ =0.33, P<0.001). Both IDF and NCEP-R criteria indicated that T2D with five criteria of MetS had higher insulin resistance (P=2.1×10-13, P=1.4×10-11), C-peptide (P=1.21×10-13; 4.1×10-11), blood glucose (P=0.01; 0.021) and HbA1c (P=0.039; 0.018) than those T2D without MetS respectively. Conclusion Although, there is a low concordance between IDF and NCEP-R criteria in the diagnosis of MetS among T2D, both criteria showed that T2D with five criteria of MetS had higher insulin resistance, blood glucose and HbA1c.
Development and characterisation of a near-infrared femtosecond optical parametric oscillator frequency comb

This thesis describes a 280 MHz MgO:PPLN-based optical parametric oscillator (OPO) synchronously pumped by a 50 fs Ti:sapphire laser to produce ultrafast pulses in the near-infrared. The OPO tuned over a wavelength range from 1450 1550 nm and 1624 1750 nm for the signal and idler respectively. The carrier-envelope-offset (CEO) frequency of the signal pulses was stabilised to a 10 MHz reference frequency without f-2f self-referencing, with an RMS phase variation of 0.56 rad over an observation time of 1 second. The relative intensity noise was measured for the CEO-stabilised OPO over an observation time of 64 seconds as 0.04%. The repetition frequency of the OPO was stabilised to 280 MHz using a frequency synthesiser at the eighth harmonic (2.24 GHz). This locking loop had an RMS phase variation of 0.98 mrad over a 1 second observation time. The CEOand repetition frequencies were then locked simultaneously to a synthesiser referenced to a Rb-disciplined source, to generate a fully stabilised 1.5 μm frequency comb with an absolute uncertainty in comb mode position of 110 Hz. The upper limit for the fractional instability for a comb mode at 200 THz was found to be 2 x 10, limited by the stability of the Rb reference. A five-fold increase in comb mode spacing to 1.4 GHz was demonstrated with the stabilised frequency comb. This was achieved using a passive filter cavity, stabilised to a transmission peak via dither locking. The FWHM bandwidth of the optical spectrum for the filtered frequency comb was reduced to 8 nm, however no increase in comb linewidth was observed. An additional experiment was carried out where an external cavity diode laser was frequency-stabilised to a saturated absorption peak in Rb at 780.2 nm using dither locking, providing an optical frequency reference for future OPO frequency combs.
Cultivar- and tissue-specific transcriptomic changes induced by cadmium in Brassica parachinensis

Background One of the main pathways for cadmium (Cd) transfer from the environment to the human body is through the consumption of leafy vegetables, and Brassica leafy crops tend to be Cd hyper-accumulators. But its response strategies to Cd still lack of systematic study. Results To investigate Brassica response strategies to Cd, we identified two cultivars with different Cd translocation efficiencies and performed mutli-transcriptomic sequencing studies under Cd treatments. Certain transporter families exhibited different temporal expression profiles in the two cultivars and may underlie the different Cd translocation efficiencies. Cd induced a drastic reduction of a 22 nt small RNA, the footprint of a pentatricopeptide repeat (PPR) protein on the chloroplast ndhB transcript and the concomitant down-regulation of the ndhB transcript. A global reduction in the expression of PPR genes was found, revealing previously unknown effects of Cd on organellar gene expression. Analyses of microRNAs (miRNAs) and their target genes by small RNA and degradome sequencing not only revealed Cd-induced changes in miRNAs but also implicated the existence of a regulatory cascade involving bra-miR156, its target gene, and bra-miR397 and bra-miR398 in Cd stress responses. Conclusions The present findings help uncover the impact of Cd stress on the transcriptome of B. parachinensis and provide candidate genes and miRNAs for further investigation.
Gratitude to Nature: Presenting a Theory of its Conceptualization, Measurement, and Effects on Pro-Environmental Behavior

Feeling grateful to nature for its bountiful benefits to humans and wanting to give thanks to nature is a familiar theme in personal stories and cultural rituals, but this emotional experience has rarely been understood scientifically. The present research fills this gap by presenting a theory of gratitude to nature. Findings from four correlational studies and one experiment robustly support its propositions. Gratitude to nature can be conceptualized as a form of benefit-triggered gratitude. The distinction between trait and state gratitude to nature was found to be valid, and both forms of gratitude can be reliably measured. Trait gratitude to nature was associated with interpersonal gratitude as well as a number of constructs relevant to the human-nature relationship (e.g., experience with nature, connectedness to nature, anthropomorphism). Also, gratitude to nature strongly and robustly motivated not only intention but also actual performance of pro-environmental behavior. The theory offers novel insights into the understanding of humans’ relations with nature and responses to environmental problems. It also suggests potential directions for environmental education and communication.

Ship Navigation Simulation Study Miami Harbor Navigation Improvement Project, Miami, Florida

Abstract : A real-time ship simulation study of the proposed design for deepening the Entrance Channel and Fishermans Channel in Miami Harbor, Florida, was made. The purpose was to determine whether deeper draft containerships could enter the harbor safely. The study showed that even with bend easements in certain critical areas, the deeper/heavier proposed ships would have difficulty entering the harbor under certain wind and tide conditions. Tidal current data for the simulation were obtained from a numerical model and were supplemented with prototype measurements.
Realized Quantiles*

Abstract This article proposes a simple approach to estimate quantiles of daily financial returns directly from high-frequency data. We denote the resulting estimator as realized quantile (RQ) and use it to forecast tail risk measures, such as Value at Risk (VaR) and Expected Shortfall (ES). The RQ estimator is built on the assumption that financial logarithm prices are subordinated self-similar processes in intrinsic time. The intrinsic time dimension stochastically transforms the clock time in order to capture the real “heartbeat” of financial markets in accordance with their trading activity and/or riskiness. The self-similarity assumption allows to compute daily quantiles by simply scaling up their intraday counterparts, while the subordination technique can easily accommodate numerous empirical features of financial returns, such as volatility persistence and fat-tailedness. Our method, which is built on a flexible assumption, is simple to implement and exploits the rich information content of high-frequency data from another time perspective than the classical clock time. In a comprehensive empirical exercise, we show that our forecasts of VaR and ES are more accurate than the ones from a large set of up-to-date comparative models, for both, stocks and foreign exchange rates.
Improvement of Stress-Induced Changes Related To Mood and Cognitive Function in Healthy Young Adults Following Supplementation With Ajwa Dates

This study tested the effects of Ajwa dates supplementation on stress-induced changes to mood and cognitive functions in healthy young adults. 20 young adults were selected to receive seven dates per day for six weeks. Subjects completed measures of mood (POMS and DASS-21 questionnaires), and cognitive functions (simple reaction time, Stroop, n-back tests) before and after six weeks of supplementation: following an acute stressor task (Trier Social Stress test). Analysis of coronary risk and renal profiles were also done before and after six weeks of supplementation. Parameters related to mood including tension subscale in POMS, and stress subscale in DASS-21 significantly improved from baseline to week six. Significant improvements were also observed in the mean reaction time of Stroop, 1-back and 2-back tests after week six. There were no changes in coronary risk and renal profile after six weeks of supplementation. Our findings indicate that Ajwa dates supplementation has the potential to alleviate stress-induced changes in mood and cognitive functions in healthy young adults without adverse effect on renal functions.
A compensation approach for two-dimensional Markov processes

Several queueing processes may be modeled as random walks on a multidimensional grid. In this paper the equilibrium distribution for the case of a two-dimensional grid is considered. In previous research it has been shown that for some two-dimensional random walks the equilibrium distribution has the form of an infinite series of products of powers which can be constructed with a compensation procedure. The object of the present paper is to investigate under which conditions such an elegant solution exists and may be found with a compensation approach. The conditions can be easily formulated in terms of the random behaviour in the inner area and the drift on the boundaries.
