RESUMO
This study was aimed at establishing whether loneliness among hotel employees in the workplace affects their psychological and emotional experiences by empirically investigating their perceptions of negative situations. A self-administered questionnaire was distributed to 300 hotel employees, after which confirmatory factor analysis was conducted to reassess the reliability and validity of the measured questionnaire items. A model of workplace loneliness, psychological detachment, and emotional exhaustion was developed and examined through structural equation modeling. The results showed that the hotel employees experienced workplace loneliness and expressed a desire to be psychologically detached from their jobs for recovery. Workplace loneliness also contributed to emotional exhaustion. Theoretical and practical implications, as well as limitations and future research directions, are discussed.

Interferon Regulatory Factor 3 (IRF3) is a member of interferon-regulated transcription factor family and is known to play an important role in the innate immune response against viral infections. In this study, the expression of IRF3 in different tissues, developmental stages, and stocking densities of olive flounder was investigated. The expression of IRF3 was observed to gradually increase in early-stage juvenile fish. The highest expression was observed in later-stage juvenile fish when immune tissues were formed. High IRF3 expression was observed in the muscles and the brain tissues. The expression of IRF3 was observed in fish at different stocking densities after viral hemorrhagic septicemia virus (VHSV) infection. It yielded an interesting expression pattern in the muscles and the brain tissues of fish stocked at low density. These observations can be used as basic data for the study of the expression of immune response-related genes against viruses based on stocking density and immune systems in other fish species.
RESUMO
COVID-19 has caused an unprecedented crisis in all industries around the world. This study sought to verify that job insecurity, as perceived by deluxe hotel employees, significantly affects their job engagement and turnover intent and to determine the moderating effect of generational characteristics. The finding showed that perceptions of job insecurity had negative effects on the engagement of deluxe hotel employees. Also, employees' job engagement can decrease turnover intent. The engagement of employees fully mediated the relationship between perceptions of job insecurity and turnover intent, and job insecurity caused by COVID-19 had a greater influence on Generation Y than Generation X in reducing job engagement, indicating that the negative impact of job insecurity is higher in Generation Y.
RESUMO
Today, organizations face risky legal and financial consequences stemming from a single sexual harassment event. The purpose of this study was to verify that the sexual harassment, as perceived by female employees, significantly affects their levels of psychological distress and workplace deviant behavior to investigate the moderating role of organizational silence and psychological detachment in the causal relationship. First, this study found that perceived sexual harassment has a negative impact on the female employees' psychological distress and workplace deviant behavior. This study's results also demonstrated that psychological distress has a positive impact on workplace deviant behavior. Additionally, the influence of perceived sexual harassment on psychological distress increased when the employees' psychological detachment was weak. Finally, limitations and future research directions are also discussed.

The caspase10 encodes an initiating caspase that plays an important role in the maintaining the cellular homeostasis by regulating the steps involved in the immune response and cell death. We investigated the expression of caspase10 during the different developmental stages and in olive flounder tissues. Caspase10 increased in the late stage of the formation of immune tissue, and high expression was observed in the gills, kidney, skin, and spleen. The current study analyzed the expressional changes of caspase10 in olive flounder infected with viral hemorrhagic septicemia virus (VHSV). One of the major causes of mass mortality, VHSV infection in olive flounder attributes to significant expression of caspase10 in the gills, spleen, skin, and kidneys. The results indicate a close association of caspase10 expression with the immune response to VHSV infection in olive flounder. The observations could form the basis data for exploration of other fish immune system.
RESUMO
Complete mitochondrial genomes of two Pleuronectid species, Clidoderma asperrimum and Verasper variegatus (Teleostei: Pleuronectiformes: Pleuronectidae) were analysed using the primer walking method. Their mitogenomes were 17,632 and 17,273 bp in total length, respectively and comprised 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes. Their gene contents and orders were similar to those of typical vertebrates. All Pleuronectid species were subdivided into three clades in the phylogenetic tree, and the two Pleuronectid species analysed in this study formed a strong monophyletic group comprising species belonging to three genera, Hippoglossus, Reinhardtius, and Verasper.
