Well-being and career change intention: COVID-19’s impact on unemployed and furloughed hospitality workers

Purpose This study aims to examine the psychological distress experienced by unemployed and furloughed hospitality workers during the COVID-19 crisis and further investigate how this distress affects their career change intentions. Design/methodology/approach Derived from a sample of 607 unemployed and furloughed hospitality workers during the COVID-19 pandemic, the data for this research are analyzed using structural equation modeling. Findings This study reveals that unemployed and furloughed hospitality workers are financially strained, depressed, socially isolated and panic-stricken due to the pandemic’s effects. These effects lead to impaired well-being and an increased intention to leave the hospitality industry. Female and younger employees are impacted to a greater extent, while furloughed workers received fewer impacts compared to their laid-off compatriots. Research limitations/implications This study suggests that lockdown restrictions need to be implemented more deliberately, and the psychological well-being of the hospitality workforce deserves more immediate and continuing attention. It advises that hospitality businesses consider furloughs over layoffs when workforce reduction measures are necessary to combat the financial crisis. Originality/value This study adds to the current literature by examining the impact of the COVID-19 pandemic from the employee perspective. New insights are offered on the psychological toll of workforce reduction strategies during the financial fallout and how these distressing experiences affect career change intention.
LATE JURASSIC AND EARLY CRETACEOUS OSTRACOD ASSEMBLAGES OF NORTHEAST CHINA

Twelve outlined osrracod assemblages from Kimmeridgian of the late Jurassic to Albian of early Cretaceous in age can be recognized in Northeast China, in which three types of sedimentary facies, i. e. the marine, the marine-terrestrial transitional brackish and the inland lacustrine facies are included, while the latter is the most developed. The distribution horizons, characteristics and epochs of the ostracod assemblages are chiefly elucidated in the present paper.
The Influence of Diet, Exercise and Education Level During Pregnancy on Child Cavities and Tooth Eruption

Objectives: This study’s objective was to evaluate if exercise during pregnancy, a healthy diet rich in polyunsaturated fatty acids and calcium, and the mother’s educational level influenced the dental health measures of caries risk and tooth eruption of their offspring. Methods: Women with children 6 years and younger completed questionnaires regarding PA and diet (PUFA-rich, calcium-rich (Ca) dairy foods) during pregnancy and education level prior to their child’s dental examination. T-tests were used to compare exercisers and non-exercisers; correlation and regression analyses were conducted to determine relationships and predictors of child dental health, respectively. Results: Eighty-two mother-child pairs were analysed. Exercisers had trends of increased PUFA (p=0.07) and Ca-rich dairy foods (p=0.12) to non-exercisers during pregnancy. Ca-rich dairy foods during pregnancy had positive associations with primary tooth count (p=0.004), mixed surface count (p=0.02), and tooth eruption (p=0.04). Controlling for maternal education and exercise, tooth eruption was predicted by PUFA summary and cheese consumption while dairy summary predicted primary tooth count; caries risk was predicted by maternal education; primary surface caries was associated with exercise duration. Conclusion: During pregnancy, calcium-rich dairy and PUFA-rich foods influenced child tooth eruption and thus tooth count, while exercise duration was associated with primary surface caries. Maternal education was associated with lower caries risk. Our findings support educating women on calcium intake and appropriate exercise levels during pregnancy, plus oral health counseling for their child.
Remittances and Inequality: The Post-Communist Region

This study aims to investigate the impact of international remittances on income inequality in the post-communist region. The association between the variables is examined via static and dynamic panel models. Using macroeconomic data from 27 countries over the period 1991-2014, we discover that income inequality progresses along a U-shaped course as a country becomes more dependent on remittances. For most of the countries, the relationship between remittances and inequality is inverse. When remittances account for more than 20% of GDP, they exacerbate economic inequality. This finding challenges the view that remittances should only be viewed as a pro-poor redistribution mechanism because in certain cases, additional migrant transfers may actually increase income inequality.
Proximity to high densities of pastoral settlements reduces grassland regrowth in a protected tropical savanna

Sedentarization of pastoralist communities is reshaping the structure and functioning of tropical savannas. Of particular concern is how permanent pastoral settlements change grassland vegetation inside “protected” areas. In this study, we investigate the spatial impact of pastoral settlements on grassland regrowth in Nech Sar National Park, Ethiopia. Within the National Park, we established herbivore exclosures across the central grassland plains at varying distances from a high concentration of pastoral settlements. Plant species composition, biomass, and regrowth after clipping were measured every 6 months, inside and outside exclosures in close proximity and further away from pastoral settlements. After 18 months, close proximity to high densities of pastoral settlements negatively influenced grassland regrowth compared to further away from pastoral settlements. Excluding herbivores resulted in lower regrowth compared to grazed swards independent of distance from high densities of pastoral settlements. Cover of the dominant grass species Bothriochloa insculpta was lower when grazed and following clipping, whereas Chrysopogon plumulosus cover was higher closer to settlements. These grasses were dominant across the plain; yet further away from settlements there was a higher number of co‐dominant grassland species. These findings suggest that subtle changes in grassland community composition, likely following livestock grazing, contribute to spatial differences in savanna grassland regrowth near to and far from pastoral settlements. Furthermore, specific grassland species may be used as indicators of the wider spatial impact of pastoral settlement sedentarization on savanna regrowth.
Antibiotic resistance in heavy metal resistant non-lactose fermenting Enterobacteriaceae colonies cultured from textile industry effluents

Many of the aquatic pathogenic microflora belong to the non-lactose fermenting (NLF) Enterobacteriaceae and emergence as well as the spread of antibiotic resistance in them is now a serious threat to public health worldwide. Growth of textile industries has heavily flourished acting as hub for the ready-made garments factories in Bangladesh. Textile industry effluents may contain heavy metals and it is not clear whether their disposal is strictly monitored or not and their impact on the aquatic microflora have not been properly investigated and monitored. To assess the impact of heavy metals on the emergence and spread of antibiotic resistance in NLF Enterobacteriaceae, samples were collected from four different locations of drains running down effluents from five (n=5) different textile industries located in Savar, Dhaka, Bangladesh. Total bacterial counts (TBCs), minimal inhibitory concentrations (MICs) of heavy metals, antibiotic susceptibility, binary exposure and plasmid profile experiments were performed. TBCs from day 1 to day 5 revealed that most colony forming units (CFUs) uncountable at 10-6 dilution could be counted at 10-10 dilution. A total of 100 NLF bacterial isolates were categorized as type-1 and type-2 using 4 differential media. The MICs of 100% isolates in both type-1 and type-2 for nickel (Ni), lead (Pb) and chromium (Cr) were 0.6 mM, 0.6 mM and 1.0 mM, respectively. In case of type-1, most (38%) showed resistance to azithromycin (AZM) and least (2%) to cefotaxime (CTX). In case of type-2, most (48%) showed resistance to AZM and least (8%) to CTX. Binary exposure experiments revealed the combined effect of heavy metals and antibiotics. Where in most cases, zone of inhibition increased or remained unchanged. In few cases, zone of inhibition decreased. This finding indicated that the heavy metals typically exert negative or no effects on antibiotic resistance in the isolates tested. Plasmid profiling of the type-1 and type-2 NLF isolates resistant to both the antibiotics and heavy metals revealed that one of the five type-1 isolates contained very large plasmid (14 Kb) and four of the eight type-2 isolates contained 13 Kb plasmids and two contained 12 Kb plasmids. These findings indicated that these isolates possibly possess the ability to sequester metals before being discharged into the soil and/or water environment. Keywords: Antibiotics, effluents, heavy metals, minimum inhibitory concentration (MIC), resistance.
College student’s attitudes about SCD carrier screening

ABSTRACT Sickle Cell Disease (SCD) is an inherited blood disorders that leads to several health problems ranging from delayed growths, recurrent infections, vision problems, chronic hemolysis, kidney disease to low quality of life and life expectancy. Beyond individuals and families, SCD has the potential of economically burdening communities and societies. A non-probability sampling approach using a convenience sample of college students was used for this study. Data were obtained through an online survey derived from a modified version of the Attitudes to Participation in Carrier Testing scale. Results indicated that overall participants had positive attitudes toward screening; however, only 26% knew their own carrier status highlighting the need for improved screening participation.
Improving Performance of Zakat Institution in Poverty Alleviation: Balanced Scorecard Approach

The purpose of this study is to develop a performance improvement model of Zakat Institution in Indonesia (OPZIS) using four balanced scorecard perspectives in poverty alleviation. The model is examined by using Structural Equation Modeling (SEM) analysis. Respondents of this study was 100 employees of 11 Zakat Institution, 100 muzzaki and 100 mustahiq. The results of this study prove that the Balanced Scorecard approach as a strategic management model can improve Zakat Institution performance. The quality of Zakat Institution performance is influenced by the organization's ability to grow and become a learning organization with training and support from supervisors. Good internal processes are created by employee satisfaction and loyalty, which ultimately affects the quality of customer service. Good quality customer service will affect customer satisfaction, which in turn, customers become more loyal and affect Zakat Institution financial performance. High financial performance will increase the contribution of Zakat Institution in poverty alleviation. This is because Zakat Institution is able to properly channel the funds to those entitled to receive it, namely the poor.
The Impact of the Global Economic Meltdown on the Manufacturing Sector in Nigeria (2005 – 2009)

As several opinions and suggestions were made on the effect of the global economic meltdown on the Nigerian economy, however, few of these studies explored the impact of the crisis on the manufacturing sector of the economy. In this study, the effort is to provide empirical evidence of the impact on the sector. To achieve this, cross-sectional and time-series data were randomly collected from thirty-one (31) quoted firms across different sectors of the manufacturing sector and for a period of five years (2005-2009). A panel model analysis was employed as the estimating technique; it was considered as the most appropriate for the study. The objectives stated in the study were achieved, as the empirical findings revealed that the global economic meltdown had an impact on the Nigerian manufacturing sector. More so, the impact was negative on the sector and on its profitability all through the periods considered, as the impact was more severe in the year 2007. It was also revealed that profitability across the manufacturing firms in Nigeria is time-variant and cross sectionals variant. Finally, a set of policy recommendations were made as a result of the findings, in order to recognize the role of the manufacturing sector as the engine of growth, whose performance is crucial for economic dependency and transformation, these policies are to help in repositioning the sector from the bad state it was before and after the period of global economic crisis to an encouraging state: The sector need to have a strategic framework for industrial development that is domesticated, emphasis should be made on local sourcing of raw materials and technology so as to save guard the economy from the future severe impact of foreign economic shock, Government should ensure tight effective border control, power generation, transmission, and distribution should be improved, bailout funds and adequate credit should be made available. These and others, if carefully implemented, the manufacturing sector will be able to yield a positive result, possible as the driver of the economy by creating wealth, employment generation and economic prosperity.
Office of the citizen: a qualitative analysis of Twitter activity during the Lekki shooting in Nigeria’s #EndSARS protests

ABSTRACT In recent times, SNSs have been influential in re-shaping social movements. Not only do they allow access to cheaper and quicker mobilization resources for demonstrators, they also allow them to circumvent conventional communication networks to create their own narratives and thus gain communicative power. Therefore, the study explores the Twitter activities of the #EndSARS protesters in Nigeria on the night of the Lekki shooting with the specific objective of evaluating the role of influencers within the movement as well as establishing the various manifestations and expressions of anger or hope as tweeted by participants in the protests. The study discovered that users relied more on foreign media than local media for coverage while Nigerians in diaspora fueled information spreading about the protests on the night of the shooting.
Improvement of Heat Pipe Solar Collector Thermal Efficiency Using Al2O3/Water and TiO2/Water Nanofluids

Heat pipe solar collectors (HPSCs) are heat exchangers that carry heat based on the phase change of the heat pipe working fluid. It is aimed to increase the operating temperature range of solar collectors by changing the phase of the working fluid in the heat pipe at low temperature. For this reason, it has become widespread to use nanofluids obtained by mixing nanosized metal oxides with the base fluid in certain proportions in order to increase both the thermal conductivity of the heat pipe working fluids and to increase the specific heat closures. The main purpose of this study, which was conducted to evaluate the performance of HPSCs, is to increase performance, and an experimental study has been conducted in this direction. For this purpose, an HPSC designed and manufactured was used. Al2O3-water and TiO2-water nanofluids containing 2% nanoparticles were used in order to increase performance in the study. HPSC used in the study consists of 8 heat pipes with a length of 100 cm. The experiments were carried out for pure water and nanofluids, and their efficiency and strength were compared. The highest value of instantaneous efficiency was calculated as 48% when pure water was used as the working fluid, 58% for Al2O3-water nanofluid, and 64% for TiO2-water nanofluid. The instantaneous power obtained using pure water was determined as 135.66 W, 167.96 W for Al2O3-water nanofluid, and 184.03 W for TiO2-water nanofluid. The improvement in efficiency was determined as 20.8% for Al2O3-water nanofluid and 33.3% for TiO2-water nanofluid. Improvement in powers was found to be 23.8% for Al2O3-water nanofluid and 35.6% for TiO2-water nanofluid.
The effect of selenium on salinity stress and selenate – sulfate comparision in kale

Abstract Increased salinity is a threat to arid and semiarid zone agriculture worldwide. Kale consumption has increased as its nutritional and antioxidant benefits become more widely known. Compared with other vegetables, it is relatively salt tolerant. However, there is limited information on its salt tolerance, nutrient uptake under saline conditions, and physiological response. We examined the yield response, physiological parameters, and mineral nutrient content of kale grown under variable conditions of salt and Se addition in a greenhouse study. The experiment consisted of four salinity levels, four Se levels, and combined salinity treatments for a total of 16 treatments each with four replications. Salinity decreased yield when irrigated at 6 and 9 dS m−1 but not at 3 dS m−1. Selenium addition increased yield at all salinity levels but did not increase salt tolerance. Addition of 0.25 mg Se per kg of soil, corresponding to leaf Se concentrations of 1 mg kg−1, was sufficient to increase yield by an average of 11% relative to control. Kale yield loss began between 3 and 6 dS m−1 irrigation water salinity and 50% yield loss occurred at EC 6.
The Static Response of Axisymmetric Conical Shells Exhibiting Bistable Behavior

Belleville springs are widely used in a variety of mechanical systems. Recent advances in the field of multi-stable structures suggest that these conical axisymmetric washers may be extremely useful as bistable building blocks for multi-stable architected metamaterials. In this paper, we examine the ability of existing analytical models to accurately predict the bistable behavior of Belleville springs, namely, a nonmonotonous force–displacement relation with two branches of positive stiffness separated by a branch of negative stiffness. By comparing with results of finite element (FE) simulations, we find that current analytical models may suffer from significant inaccuracies associated with the assumption of rigid rotation. According to this assumption, adopted by all analytical models of Belleville springs, the cross section of the spring rotates without bending, i.e., maintains zero curvature as the spring deforms. Motivated by this insight, we relax the rigid-rotation assumption and approximate the radial displacement field by a linear relation in terms of the distance from the spring axis. We find, based on extensive finite element simulations, that the functional dependence of the radial displacement on the geometry of the springs is indifferent to the stage of deformation and can be expressed in terms of three geometrical parameters. These findings enable us to derive closed-form expressions that are simple and straightforward to use, yet are significantly more accurate than existing analytical models.
Brand Secret Micro-Collectives

Brand secrets are discoverable locations, options, and experiences selectively shared with a smaller subset of consumers. This article introduces the related construct of a brand secret micro-collective, a miniature consumer social group bound by shared special knowledge of a brand secret. We explore the experiential arcs associated with the bonds of shared special knowledge in brand secret micro-collectives.
Identifying groups of determinants in Bayesian model averaging using Dirichlet process clustering

Model uncertainty is a pervasive problem in regression applications. Bayesian model averaging (BMA) takes model uncertainty into account and identifies robust determinants. However, it requires the specification of suitable model priors. Mixture model priors are appealing because they explicitly account for different groups of covariates as robust determinants. Specific Dirichlet process clustering (DPC) model priors are proposed; their correspondence to the binomial model prior derived and methods to perform the BMA analysis including a DPC postprocessing procedure to identify groups of determinants are outlined. The application of these model priors is demonstrated in a simulation exercise and in an empirical analysis of cross‐country economic growth data. The BMA analysis is performed using the Markov chain Monte Carlo model composition sampler to obtain samples from the posterior of the model specifications. Results are compared with those obtained under a beta‐binomial and a collinearity‐adjusted dilution model prior.
Experimental and Theoretical Analysis of Heat Transfer Characteristics of Spray Cooling in a Closed Loop

Spray Cooling is a promising candidate to provide high rate heat flux removal in spacecraft thermal control.A mathematical model of spray cooling heat transfer characteristics is presented based on the fundamentals of bubble dynamics and heat transfer,and the predictions by the model coincide well with the experimental results in this paper.The heat transfer characteristics including spray cooling curve,temperature gradient on the heating surface and so on in a closed loop are obtained by both experiment and model simulation.The analyzed results show that:1) the temperature distribution on the heating surface is not uniform,however the maximal temperature difference is less than 5℃;2) spray cooling curves are almost in the two phase region,thus resulting in that the heat transfer in the closed loop system is stronger than that under the normal pressure condition due to the lower pressure in the spray chamber.
Home advantage in soccer after the break due to COVID-19 pandemic: does crowd support matter?

ABSTRACT The present study aimed to investigate the impact of the return of different European leagues and their divisions after the break due to the COVID-19 pandemic, without the crowd support, on home advantage (HA). Data from the first and second divisions of the 2016/2017, 2017/2018, 2018/2019 and 2019/2020 seasons of the German, Spanish, English and Italian leagues were analysed to obtain overall HA. As 2019/2020 season was interrupted due COVID-19 pandemic, we also calculated the home advantage in a fractional way: phases 1 and 2 played before and after the break, respectively. HA in first division of the German (F 3,51 = 4.86, P = .01, = 0.22, large) and Italian (F 3,57 = 4.50, P = .01, = 0.19, large) leagues were lower in 2019/2020 season compared with other seasons. Furthermore, HA decreased in phase 2 in four of the seven leagues and divisions analysed, with no advantage in first and second divisions Germany (45.1 ± 21.3%) and Italy (49.8 ± 18.5%), respectively. A positive correlation (0.82 ± 0.10; P < .01) and significant relationship (R 2: 0.69 ± 0.16; SEE: 4.36 ± 0.76; P < .01) were found between HA and team quality for all analysed leagues and divisions during the 2019/2020 season. The findings of the present study reveal that HA was affected in the 2019/2020 season, especially after the break due to the COVID-19 pandemic without crowd support.
