BackgroundAcute respiratory infection (ARI) is the leading cause of morbidity and mortality in pediatric patients worldwide and imposes an intense pressure on health care facilities. Data on the epidemiology profiles of ARIs are scarce in the western and rural areas of China. The purpose of the current study is to provide data on the presence of potential pathogens of ARIs in hospitalized children in Chengdu, west China.MethodsRespiratory specimens were obtained from hospitalized patients (under 6 years old) with ARIs in a local hospital in Chengdu. Eight respiratory viruses were identified by PCR and 6 respiratory bacteria by biochemical reactions and Analytical Profile Index (API). Pathogens profiles, clinical characteristics and seasonality were analyzed.ResultsFifty-one percent of patients were identified with at least one respiratory pathogen. Human rhinovirus (HRV) (23%), Respiratory syncytial virus (RSV) (22.7%) was the most commonly identified viruses, with Klebsiella pneumoniae (11.5%) the most commonly identified bacterium in the study. The presences of more than one pathogen were found, and multiple viral, bacterial, viral/bacterial combinations were identified in 14.9, 3.3 and 13.9% of patients respectively. Respiratory viruses were identified throughout the year with a seasonal peak in December–February. Pathogens profiles and clinical associations were different between infants (< 1 year of age) and older children (> 1 year of age). Infants with ARIs were more likely to have one or more viruses than older children. Infants identified with multiple pathogens had significantly higher proportions of tachypnea than infants that were not.ConclusionsThis study demonstrated that viral agents were frequently found in hospitalized children with ARI in Chengdu during the study period. This study gives us better information on the pathogen profiles, clinical associations, co-infection combinations and seasonal features of ARIs in hospitalized children, which is important for diagnoses and treatment of ARIs, as well as implementation of vaccines in this area. Moreover, future efforts in reducing the impact of ARIs will depend on programs in which available vaccines, especially vaccines on RSV, HRV and S. pneumoniae could be employed in this region and new vaccines could be developed against common pathogens.

Purpose This study aims to critically review the research on the phenomenon of discrimination in hospitality and tourism services to identify the key thematic areas, scenarios, antecedents and consequences; to provide theoretical propositions for future research; and to propose practical strategies to reduce discrimination and to improve equality in the field. Design/methodology/approach This paper adopts the preferred reporting items for systematic reviews and meta-analyses guidelines to collect relevant academic work on discrimination in hospitality and tourism services from 1985 to 2020 and critically reviews and analyses the studies through bibliometric analysis, content analysis and critical analysis. Findings The findings show that the main sources of discrimination in hospitality and tourism services include sexism, racism, ethnocentrism, lookism and ego-altruism. Discrimination-related research has temporal and geographical variations. A research map is proposed to present existing knowledge of discrimination in hospitality and tourism services, which indicates that while the impacts (at the individual, organizational and institutional levels) of discrimination in hospitality and tourism services have been thoroughly researched, the nature and characteristics of the phenomenon remain context-based and poorly conceptualized. Practical implications An anti-discrimination guideline for hospitality and tourism practitioners is designed to cope with and eliminate discriminatory situations. This evidence-based guideline provides useful coping strategies based on the prevent–monitor–manage principle. Originality/value This paper is comprehensive in its scope, methodology and wide coverage of discrimination-related research in hospitality and tourism services. It is the first attempt to review this phenomenon in the existing literature and identifies the research gaps and future research agendas.

A B S T R A C TThis study examines the effects of both specialization in tourism and market competition on the efficiency of the hotel industry. For this purpose, stochastic frontier analysis (SFA) was employed to evaluate the efficiency of the hotel industry on a provincial level in China and to analyze how it is impacted by specialization in tourism and market competition. The results confirm that tourism specialization and market competition exert a synergistic effect on hotel industry efficiency in China. This study finds that tourism development as represented by a high level of tourism specialization by a destination does not guarantee high efficiency in hotels but does enhance the negative effect of market competition on hotel industry efficiency. Significant policy and managerial implications stem from these findings.
