An investigation of underlying dimensions of customers’ perceptions of a safe hotel in the COVID-19 era: effects of those perceptions on hotel selection behavior

ABSTRACT This study focuses on the guests’ perceptions of a safe hotel within the context of COVID-19. Based on the principles of the Social Exchange Theory, it (1) explores the underlying dimensions of a safe hotel image in the COVID-19 era, and (2) evaluates the relationships of these dimensions with future hotel guests’ selection behaviors. The data were gathered from a sample of 500 hotel guests via an online survey instrument. A purposive sampling method was employed. Factor analysis and multiple regression analysis were carried out. Four dimensions were distinguished: Medical Preparedness, Hygiene Control, Health Communication, and Self-service Technology. Findings revealed significant influence of these dimensions on hotel selection behaviors. Hygiene control was found to be the most important predictor for future hotel selection behaviors. These findings provide critical strategic recommendations to help hoteliers assure and project a safe hotel image in the COVID-19 era.
DETERMINANTES DA INFORMALIDADE E DESEMPREGO NO MERCADO DE TRABALHO DA REGIÃO METROPOLITANA DO RECIFE

In view of the importance of better understanding the labor market, the present study evaluates the behavior of the determinants of informality and unemployment through an econometric model that estimates the chances of an individual being in such employment status, the Probit model for the period of employment, 2010. The determinants that had the greatest impact in order to reduce the chances of belonging to the informal sector or being unemployed were: education, age, marital status, position at home and race, in addition to a neighborhood composition adopted in the study. In order to make a comparison between the genders, it also estimates the equations separated by genders. Among the differences found, the main one was that, although the impact of education on the probability studied was the most important among the factors analyzed for both genders, it was more striking among women.
Laboratory and Field Performance of Five Cheap Commercial Light Traps for Capturing Mosquitoes In China

BackgroundMosquito light traps for household use are popular because they are small, cheap, user friendly, and environmentally friendly. At present, there are many variations and specifications of mosquito traps intended for household use on the market. Their labels claim they are powerful, but research and evaluation of their claims is lacking.MethodsThis article tested the key parameters, the laboratory capture rates, and the field capture rate of 5 popular mosquito traps intended for household use. ResultsThe study found that in the laboratory experiment, the capture rate of the mosquito traps selected was between 34.7%-65.0%. The analysis showed that the fan speed, and design of the air guide of the traps are important factors that affect the mosquito catch rate. Field tests in the greenhouse found that the 5 mosquito traps had high catch rates for Culex quinquefasciatus. The average percentage of Cx. quinquefasciatus, Aedes albopictus, Anopheles sinensis, and other flying insects captured every night was 51.76%, 25.29%, 14.12%, and 8.82%, respectively. There was no significant difference in the capture rate of Ae. Albopictus and An. sinensis by the 5 mosquito traps in the greenhouse, but a significant difference in the catch rate of Cx. Quinquefasciatu. ConclusionsThe ultraviolet wavelength (395-400nm) involved in the selected mosquito traps is not the main reason that affects the mosquito catching effect, but the fan speed and the air guide may be the reason for the difference in the catching effect among the five mosquito traps. Therefore, the mosquito traps intended for household use can be improved by adjusting the fan speed and optimizing the air guide.
An examination of the psychometric properties of the occupational identity questionnaire for community-living elderly who require care

Introduction Authors created an Occupational Identity Questionnaire Provisional version (OIQ-P) to assess occupational identity for elderly individuals. The purpose of this study was to examine the psychometric properties of the OIQ-P. Methods Participants included 135 (42 males) elderly who lived locally and required care or support. OIQ-P was evaluated in terms of structural validity, criterion validity and internal consistency. Results Based on the results of an exploratory factor analysis and confirmatory factor analysis, an OIQ with a factor structure of 3 factors and 14 items was created. Rasch rating scale model revealed that 14 participants and 1 item did not fit the goodness of fit, nevertheless, the overall result was good. Spearman's rank correlation coefficient indicates that there was a law correlation between OIQ and the occupational identity scale of the Occupational Performance History Interview Version 2. In terms of internal consistency, the person separation index and person separation reliability coefficient were 2.30 and 0.84, respectively. Conclusion This study confirmed the structural validity, criterion validity and internal consistency for the OIQ. To enhance the clinical utility of the OIQ, it is necessary to examine the interpretability and conduct an intervention study using the OIQ.
Enzymatic flow injection analysis of coprostanol in non-aqueous media

An alternative method has been developed for the spectrophotometric determination of coprostanol in sediments, based on its extraction with chloroform-methanol(2+1 v/v) and enzymatic analysis in pH 7.0 buffer saturated toluene, using a bienzymic reactor prepared with 1 mg cholesterol oxidase (23 IU) and 1 mg horseradish peroxidase (220 PU) both noncovalently immobilised on controlled pore glass beads. The method allow us to determine coprostanol in a dynamic range from 2.2xl0-4 M to 9x10-4 M , measuring the absorbance at 458 nm of the oxidized form of p-anisidine. The relationship between absorbance (A) and coprostanol concentration (C) expressed in mol.L-1 was A = (0.0059 ± 0.0005) + (17 ± 1) (C) with a r2 = 0.998 and it was obtained a limit of detection of 7x10-6 M in the best experimental conditions. Recovery studies carried out on water and beach sediments, at concentration levels from 0.1 to 0.25 mg.g1, provided values from 96 to 112%.

In conclusion: The use ofoverdoses than permissible of sorbitol and aspartame for a prolonged period leads to disturbance of lipidprofile levels, but it is statistically imperceptible.
The Correlation of ELP4-PAX6 With Rolandic Spike Sources in Idiopathic Rolandic Epilepsy Syndromes

Objective: To study the single nucleotide polymorphism rs662702 of ELP4-PAX6 in patients with idiopathic rolandic epilepsy syndromes (IRES) in China and explore the relationship between the distribution of rolandic spike sources and the single nucleotide polymorphism rs662702 in ELP4-PAX6. Methods: First, clinical information was obtained from patients diagnosed with IRES. Next, the single nucleotide polymorphism rs662702 of ELP4 was analyzed by using the Sanger method. Resting-state magnetoencephalography data were collected from 17 patients. We analyzed the epileptic spike sources using the single equivalent current dipole (SECD) model and determined the spike distributions across the whole brain. Finally, Fisher's test was performed to assess the correlation between the single nucleotide polymorphism rs662702 of ELP4-PAX6 and rolandic spike sources. Results: ELP4 rs662702 T alleles were found in 10.7% of IRES patients and occurred four times more frequently in these patients than in the healthy controls. TT homozygosity was found in one IRES patient (1.3%), while no TT homozygosity was found in the healthy control group. The IRES rolandic spike sources were unilateral in sixteen patients (94.1%) and were mainly located in the anterior central gyrus (58.8%). The spike source of patients without the ELP4 rs662702 T allele was correlated with the central region (p < 0.05). The rolandic spikes sources were significant correlated with the non-central gyrus (frontal and temporal lobes) in patients with the ELP4 rs662702 T allele (p < 0.05). Conclusion: The rolandic spike sources of the IRES patients with the ELP4 rs662702 T allele were significantly associated with the non-central gyrus, including the frontal and temporal lobes. Our study confirmed for the first time in vivo that ELP4 rs662702 T allele overexpression is correlated with the rolandic spike distribution in patients with IRES and provides important insights into how genetic abnormalities can lead to brain dysfunction and into the precise targeting of abnormal discharge sources in the brain.
Association of Helicobacter pylori Infection and Atrophic Gastritis with Chronic Renal Insufficiency in Yaounde Cameroon, Using Gastropanel® Serological Biomarker Panel (Pepsinogen I; Pepsinogen II; Gastrin-17; Helicobacter pylori Igg)

Introduction: Helicobacter pylori infection is associated with an atrophic gastritis peptic and duodenal ulcer and gastric cancer. Patients with chronic renal diseases usually have dyspeptic symptoms. Several investigations have demonstrated an association between H. pylori infection and chronic kidney disease, although their results are still conflicting. We therefore aimed, to clarify the prevalence of H. pylori infection in patients receiving dialysis. Materials and Methods: Patients undergoing hemodialysis were recruited at the University Teaching Hospital of Yaounde, between January and May 2019. The clinical and socio-demographic information of the patients was recorded. 5 ml of blood were collected aseptically for Pepsinogen I and II enzymes, gastrin17 hormone and IgG anti H. pylori anti-body. The test parameters were analyzed using a GastroSoft software application. The data was analyzed using Epi Info 7.0. All statistics were 95% CI. Ethical clearance was also obtained from the National Ethics Committee. Authorization was obtained atthe University Teaching Hospital. Results: A total of 60 subjects were recruited aged 25-74 years, (mean±SD 52.03 ± 12,78) years;22(45.16%) females, aged 29 to 71years(mean±SD 47,45 ± 11.46) years and 38(54.84%) males aged 25 to 74 (mean±SD 56,47±12.25) years. Female / male ratio was 1.2. Overall, 26(43.33%) subjects were positive for H. pylori infection (IgG≥30EIU). The prevalence of atrophic gastritis obtained was (23.33%)(PG1< 30µg/l). The mean H. pylori IgG antibodies were significantly higher in obese than non obese subjects (F=3.59; p=0,01). A significant increase in the mean creatinine(P=0.008), andurea (P=0,05) was observed in H. pylori positive than negative ones. Conclusion: H. pylori infection is highly prevalent amongst patients with chronic renal failure and may thus require continuous follow up.
The Impact of Deviant Strategy on Corporate Innovation Performance: The Moderating Role of Equity Incentives and Market Competition

Related research has pointed out that the choice of corporate strategy can affect corporate performance, but the relationship between deviant strategy and corporate innovation performance has not been revealed. This article uses the 2007-2017 Chinese A-share listed companies as samples. The study found that corporate innovation performance is affected by deviant strategy, and there is a positive correlation between them; equity incentives will strengthen the relationship between deviant strategy and corporate innovation performance; however, market competition will weaken the relationship between deviant strategy and the innovation performance of enterprises. This research has certain theoretical significance and provides relevant suggestions for management practice
Spondias mombin Seed Oil Compounds Identification by Raman Spectroscopy and NMR

Spondias mombin L. has been used in traditional medicine to treat some cases such as infections and inflammations. Some researchers have reported that its biological components, such as carotenoids, carotenes, and phenols, have been characterized primarily by HPLC analysis. Here, we report on the characterization of Spondias mombin L. seed oil by Raman spectroscopy, and the profile identification of fatty acids by 1H-NMR and 13C-NMR spectroscopy. The oil was extracted from different weight volumes of seeds using organic solvent, and each batch was characterized. The analysis of the fatty acid profile by NMR indicated that the seed oil is highly unsaturated (monounsaturated: 29.4% and polyunsaturated: 43.5%). Molecular Raman vibrations at 1006, 1158 and 1523 cm−1 showed the presence of carotenoids, which in turn performed an antioxidant activity. This was demonstrated by a 2,2′-Azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) method. The cell viability in colon cancer cells was promoted in the presence of the oil. The compounds identified in this study from seed oil could be an interesting proposal for food or pharmaceutical applications.
Prevalence of MDR-TB Based on Demographic Factors Among Patients Attending Nauth and St Patrick’s Hospital Mile 4 Abakaliki in Southeast Nigeria

This study was designed to determine the prevalence of multi-drug resistant tuberculosis (MDR-TB) among pulmonary tuberculosis patients attending NnamdiAzikiwe University Teaching Hospital (NAUTH) Nnewi and St Patrick’s Hospital Mile 4 Abakaliki demographically. Patients with persistent cough for over two weeks were screened by Ziehl-Neelsen ZN technique for the presence of acid fast bacilli (AFB) in their sputum and a total of 103 patients with AFB positive sputum samples were recruited. The positive sputum samples were subjected to Xpert MTB/RIF assay (GeneXpert®, Cepheid USA) and culture on Lowestein Jensen medium for 42 days at 37°C. Drug susceptibility testing was done on the isolates using the nitrate reduction assay (NRA). Eighty-three 83 (80.6%) of the isolates were obtained from culture after suspected colonies were subjected to morphological, biochemical, and immunological tests and out of the 83 (80.6%) samples analysed by Xpert MTB/RIF assay 45 (67.2%) were rifampicin resistant. Age group 26-35 years showed the highest proportion of positive culture results (33.7%) followed by age group 18-25 (28.8%) years. Demographically, age group 26-35 years had a high prevalence rate of MDR-TB (50.0%) and female gender also showed high prevalence rate of MDR-RB (48.5%). Strikingly, educational status was significantly associated with MDR-TB (P=.020). St Patrick’s hospital had a high prevalence rate of MDR-TB (46.94%) when compared with NAUTH (38.9%) and these indicates that there is high prevalence of MDR-TB among patients with pulmonary TB in these sites. The demographic results of this study calls for urgent and serious intervention as MDR-TB prevalence is increasing even in the face of intense national TB control program.
DNA Preparation In Vitis Vinifera L. for Third Generation Sequencing

Background: There have been several attempts to sequence the genome of Vitis vinifera L. (grapevine), utilizing low-resolution second-generation platforms. Nevertheless, the characterization of the grapevine genetic resources and its adaptation to vulnerable conditions could be better addressed through extensive and high-resolution genome sequencing.MinION is a third-generation sequencer preferred by many laboratories due to its relatively low cost, ease of use and small size. Even though this long-read technology has been rapidly improving, to reach its full potential requires high-quality DNA.Results: Here we establish a workflow for DNA extraction suitable for MinION sequencing long reads from grapevine. This protocol was tested with leaf samples from different positions on annual growing branches of grapevine, Purified nuclei from fresh young leaves that led to high quality, long DNA fragments, suitable for long-read sequencing were successfully generated. It is evident that longer reads in grapevine associate with both fresh tissue and adjusted conditions used for nuclei purification.Conclusions: We propose that this workflow presents a significant advancement for long-read quality DNA isolation for grapevine and likely other plant species.
What is our power to detect device effects in animal tracking studies?

The use of bio‐logging devices to track animal movement continues to grow as technological advances and device miniaturisation allow researchers to study animal behaviour in unprecedented detail. Balanced against the remarkable data that bio‐loggers can provide is a need to understand the impact of devices on animal behaviour and welfare. Recent meta‐analyses have demonstrated the impacts of device attachment on animal behaviour, but there is a concern about the frequency and clarity with which device effects are reported. One aspect lacking in many studies is assessment of the statistical power of tests of device effects, yet such information would assist the interpretation of results. We address this issue by providing an overview of the statistical power, as well as the Type M (magnitude) and Type S (sign) error rate, of tests of device effects within the avian tracking literature across a range of assumed effect sizes. The median power of statistical tests ranged from 9% to 65% across a range of assumed effect sizes corresponding to benchmark values for small, moderate and large effects (d = 0.2, 0.5, 0.8, respectively). Moreover, when using effect sizes derived from previous a meta‐analysis (d = 0.1), median power was only 6%. When assuming smaller effect sizes, statistical tests were characterised by high Type M and Type S error rates, suggesting that statistically significant results of device effects will tend to exaggerate the size of such effects and may estimate the sign of an effect in the wrong direction. Well‐designed tracking studies will reduce device effects to low levels and consequently issues associated with low power will be commonplace. Nevertheless, assessment of device effects remains important, particularly when embarking on novel tracking studies. We recommend that statistical tests of device effects are reported clearly and are routinely accompanied by assessment of statistical power, including Type M and Type S errors, based upon realistic external estimates of effect size. Reporting the statistical power can help avoid the pitfalls of overstating results from individual studies, shift the emphasis to accurate reporting of effect sizes and guide decisions about the ethical impacts of device attachment.

CONTRACEPTIVE STEROIDS INCREASE ERYTHROCYTE LIPID PEROXIDATION IN FEMALE RATS(

In order to investigate the effects of contraceptive steroid combinations on lipid pcroxidation in the erythrocyte membranes, adult female rats were divided into 2 groups for short- and long-term investigations; each group was then subdivided into 5 subgroups according to orally given low and high doses of EE/NEA (ethinyl estradiollnorethisterone acetate) and EULNG (ethinyl estradiolllevonorgestrel) combinations and control group. Since EE was included in each combination, the groups were named according to the progestin (NEA, LNG) components. At the end of the experiment periods, lipid peroxidation in the erythrocyte membranes from rats was measured. When compared to the controls, except low-dose LNG groups, lipid peroxidation levels were increased in all study groups. It was seen that the effect of NEA and LNG combinations on lipid peroxidation was not time-, but dose-dependent. When these combinations were compared to each other, different effects of NEA and LNG on hpid peroxidation were not detected in the experiment period. As a result, the increased lipid peroxidation following the administration of contraceptive steroid combinations is a very important finding that should be taken into account. in addition to the effects of these steroids on lipid and lipoprotein metabolism.
Application of the Sequence Planner Control Framework to an Intelligent Automation System with a Focus on Error Handling

Future automation systems are likely to include devices with a varying degree of autonomy, as well as advanced algorithms for perception and control. Human operators will be expected to work side by side with both collaborative robots performing assembly tasks and roaming robots that handle material transport. To maintain the flexibility provided by human operators when introducing such robots, these autonomous robots need to be intelligently coordinated, i.e., they need to be supported by an intelligent automation system. One challenge in developing intelligent automation systems is handling the large amount of possible error situations that can arise due to the volatile and sometimes unpredictable nature of the environment. Sequence Planner is a control framework that supports the development of intelligent automation systems. This paper describes Sequence Planner and tests its ability to handle errors that arise during execution of an intelligent automation system. An automation system, developed using Sequence Planner, is subjected to a number of scenarios where errors occur. The error scenarios and experimental results are presented along with a discussion of the experience gained in trying to achieve robust intelligent automation.
