Resumo Nas últimas décadas, cresceu o interesse em compreender os mecanismos do desempenho da recuperação de serviço (DRS) na indústria hoteleira. Este estudo introduz uma perspectiva interativa que incorpora fatores extrínsecos e intrínsecos, investigando a influência da liderança inclusiva e da autonomia no trabalho na autoeficácia dos funcionários, sendo que a autoeficácia medeia a suas relações com o DRS. A atuação superficial é proposta como um moderador negativo. Questionários foram aplicados a uma amostra de 83 supervisores e 350 funcionários de front office de 8 hotéis chineses. As metodologias de análise baseiam-se no PLS-SEM e análise de regressão. Os resultados mostram que a liderança inclusiva e a autonomia no trabalho contribuem para uma autoeficácia forte e um DRS aprimorado. A atuação superficial modera a relação entre a liderança inclusiva e a autoeficácia, mas não entre a autonomia no trabalho e a autoeficácia. Esta pesquisa transversal oferece implicações práticas para os gestores hoteleiros, fornecendo orientações para promover ambientes que estimulem a autoeficácia e aprimorem o DRS. As limitações incluem a dependência de medidas autorrelatadas e um design transversal. Pesquisas futuras podem explorar outros moderadores e mediadores, diferentes setores industriais e utilizar designs longitudinais ou experimentais para estabelecer causalidade.

Abstract In recent decades, interest has grown in understanding the mechanisms of service recovery performance (SRP) in the hospitality industry. This study introduces an interactive perspective incorporating both extrinsic and intrinsic factors, investigating the roles of inclusive leadership and job autonomy on employee self-efficacy, with self-efficacy mediating their relationships with SRP. Surface acting is proposed as a negative moderator. A sample of 83 supervisors and 350 frontline employees from 8 Chinese hotels completed questionnaires. Data analysis was conducted using PLS-SEM in Smart PLS 4 and regression analysis in SPSS 25. Results show that inclusive leadership and job autonomy contribute to strong self-efficacy and enhanced SRP. Surface acting moderates the relationship between inclusive leadership and self-efficacy but not between job autonomy and self-efficacy. This cross-sectional survey offers practical implications for hospitality managers, providing guidance on fostering environments that promote self-efficacy and enhance SRP. Limitations include reliance on self-reported measures and a cross-sectional design. Future research could explore other moderators and mediators, different industries, and use longitudinal or experimental designs to establish causality.

ABSTRACT A novel inclusion complexes nanofibrous membrane fluorescent sensor was prepared for recognizing F- via electrospinning and host–guest interaction. The host α-cyclodextrin on the surface of the electrospun nanofiber membrane is assembled into the guest azobenzene molecule which modified with F- fluorescent probe, and the formation of the inclusion complex is fixed on the surface of the nanofibrous membrane without external force, to prepare a novel surface controllable composite nanofiber membrane for F- detection. The inclusion complexes nanofibrous membrane exhibited favourable sensitivity and selectivity for F-. The introduction of F- would result in notable fluorescent decreasing of the membrane, but the other most common anions would not disturb the detection of F-. Moreover, this nanofibrous membrane was not only a fluorescent sensor for detecting F-, but also a good adsorbent for F- in solution.

Com base na teoria do envolvimento no lazer, este estudo examina como os impactos negativos dos eventos desportivos influenciam o bem-estar subjetivo do público, o que afeta ainda mais o apoio ao evento. O envolvimento no lazer é ainda utilizado para testar o efeito moderador desse relacionamento. Ao distribuir questionários no local durante os quatro dias do Grande Prémio de Macau de 2018, foram analisados 620 inquéritos válidos. Os resultados sugerem que: (a) o impacto negativo percebido pelas audiências do Grande Prémio de Macau influencia negativamente o seu bem-estar subjetivo; (b) quando o envolvimento no lazer é baixo, a relação negativa entre o impacto negativo do Grande Prémio de Macau e o bem-estar subjetivo das audiências foi aliviado; (c) os efeitos indiretos do impacto negativo percebido pelo público no apoio a eventos desportivos por meio do bem-estar subjetivo foram amortecidos pelo envolvimento no lazer, de modo que os efeitos indiretos foram encontrados apenas em díades com menor envolvimento no lazer, mas não em díades com maior envolvimento no lazer. Também são discutidas contribuições teóricas e implicações práticas para o governo de Macau e para a organização do Grande Prémio de Macau.

Drawing on leisure coping theory, this study examines how negative impacts of sport events influence audiences’ subjective well-being, which further affects the support of the event. Leisure engagement is further employed to test its moderating effect of this relationship. By distributing questionnaires on-site during the on-going four days of the Macau Grand Prix 2018, 620 valid audiences were surveyed. The findings suggest that (a) audiences’ perceived negative impact of the Macau Grand Prix negatively influence their subjective well-being, (b) when the leisure engagement was low, the negative relationship between negative impact of the Macau Grand Prix and audiences’ subjective well-being was alleviated, and (c) the indirect effects of audiences’ perceived negative impact on support for sport events via subjective well-being was buffered by leisure engagement, such that the indirect effects were only found in dyads with lower leisure engagement, but not in dyads with higher leisure engagement. Theoretical contribution and practical implications for Macau government and organization of the Macau Grand Prix were also discussed.

The present study was to investigate the effects of visfatin on the morphological structure and function of the rat uterus during inflammation. The expression and distribution of visfatin, morphological structure, eosinophils (EOS), myeloperoxidase (MPO) and cytokines in the uterus of the LPS-induced rat were studied using hematoxylin-eosin staining (HE), immunohistochemical methods, western blots and enzyme-linked immunosorbent assay (ELISA). The present study showed that visfatin positive cells dispersed widely in the uterus, and strong positive staining was observed mainly in the cell cytoplasm. Compared with saline group, in visfatin group, more uterine glands were found, EOS increased, and the difference was significant (P<0.05), MPO reduced, and the difference was significant (P<0.01). In addition, visfatin was able to increase the secretion of IL-1b, IL-6, and TNF-a (P<0.01). Compared with LPS group, in vifatin+LPS group, the uterine glands of the lamina propria increased, the myometrium became thinner, the number of EOS and MPO reduced obviously, but the difference was not significant (P>0.05), and after LPS stimulated body, visfatin decrease the level of IL-1b, IL-6, TNF-a (P<0.01). The above results suggest that visfatin could affect the morphological structure of rat uterus; Visfatin could modulate the inflammatory response in rats' uterus by regulating the quantity of inflammatory cells, such as EOS and MPO, and the level of inflammatory cytokines, such as IL-1b, IL-6, TNF-a.

El objetivo del presente estudio fue investigar los efectos de la visfatina sobre la estructura morfológica y la función del útero de la rata durante la inflamación. Se estudiaron la expresión y distribución de la visfatina, la estructura morfológica, eosinófilos, mieloperoxidasa y citoquinas en el útero de rata mediante la tinción de H&E, métodos inmunohistoquímicos, Western blots y ELISA. El estudio mostró que las células visfatina positivas se dispersan ampliamente en el útero, junto a una fuerte tinción positiva, principalmente en el citoplasma de la célula. En comparación con el grupo control, en el grupo visfatina, se encontraron más glándulas uterinas, se observó un aumento de EOS y la diferencia fue significativa (p<0,05), MPO reducida siendo esta diferencia también significativa (p<0,01). Además, la visfatina fue capaz de aumentar la secreción de IL-1b, IL-6 y TNF-a (P<0,01). En comparación con el grupo LPS, visfatina+grupo LPS, las glándulas uterinas de la lámina propia aumentaron, se observó un miometrio más delgado, y número reducido de EOS y MPO, sin embargo, la diferencia no fue significativa (P>0,05). Después de estímulo LPS en el cuerpo, se registró un nivel menor de visfatina en IL-1b, IL-6, TNF-a (P<0,01). Los resultados anteriores sugieren que visfatina podría afectar a la estructura morfológica del útero de rata. Además, podría modular la respuesta inflamatoria en el útero mediante la regulación de la cantidad de células inflamatorias, tales como EOS y MPO.
