Published: January 2021

Purpose
The prevalence of artificial intelligence (AI) has considerably affected management and society. This paper aims to explore its potential impact on hospitality industry employees, bringing enlightenment to both employees and managers.

Design/methodology/approach
Data were collected from a survey of 432 employees who worked in full-service hotels in China. Structural equation modeling (SEM) was used to analyze the data.

Findings
Results presented a positive relationship between AI awareness and job burnout. No significant direct relationship was found between AI awareness and career competencies. Organizational commitment mediated the relationship between AI awareness and career competencies, as well as the relationship between AI awareness and job burnout.

Research limitations/implications
This study contributes to human resource management in the hospitality industry to theoretical and practical aspects. Theoretically, it enriched both career theory and fit theory. Practically, this study reminds managers to pay attention to the adverse effect of AI on human capital. It also enlightens the manager to think of the positive effects that AI may bring. Managers should provide proper support to overcome AI’s threat to human resources.

Practical implications
Practically, this study reminds managers to pay attention to the adverse effect of AI on human capital. It also enlightens the manager to think of the positive effects that AI may bring. Managers should provide proper support to overcome AI’s threat to human resources.

Originality/value
The study aims to analyze the impact of AI from a career perspective. It provided theoretical support and evidence for hotel managers for the effects of AI awareness on hotel employees. The study conveys a potential topic of concern that the hospitality industry may face in the future.
Are mom-and-pop and professional hosts actually competing against hotels?
Authors: Sainaghi Ruggero , Baggio Rodolfo 
Published: January 2021

Purpose
This paper aims to examine the question of whether commercial, peer-to-peer accommodation platforms (Airbnb, in particular) and hotels are in fierce competition with each other with the possible presence of substitution threats, and compares the time series of the occupancy values across two supplier types.

Design/methodology/approach
The cities of Milan and Rome are used as case studies for this analysis. To assess the extent of synchronization, the series of Airbnb and hotels are transformed into a series of symbols that render their rhythmic behavior, and a mutual information metric is used to measure the effect.

Findings
The results show that Airbnb hosts and hotels have different seasonal patterns. The diverse occupancy trends support the absence of direct competition between Airbnb and hotels. The findings are consistent in the two analyzed cities (Milan and Rome). Interestingly, there are higher similarities between seasonal occupancy series of Airbnb listings in Milan and Rome, on one side, and hotels in Milan and Rome, on the other, than between Airbnb and hotels in the same city.

Research limitations/implications
The findings show a progressive de-synchronization (within mutual information) among the five groups of Airbnb hosts triggered by the rising professionalization degree. This result suggests the existence of a partial different business model for multi-listing hosts.

Practical implications
The study illustrates an absence of any substitution threat between Airbnb and hotels in both cities. This could have important consequences, especially for the pricing and revenue management policy. In fact, the higher the substitution threat, the higher the attention that Airbnb entrepreneurs should pay to the pricing strategy implemented by hotels, and vice versa.

Originality/value
This study sheds new light on the competition threat between Airbnb and hotels. In this study, hotels and Airbnb hosts appear as two very separate markets.
A leadership maturity model for implementing Six Sigma in academic institutions – using case studies to build theory
Authors: Anthony Stephen Graham , Antony Jiju 
Published: January 2021

Purpose
The purpose of this paper is to present a maturity model for academic leadership teams to benchmark their ability to deliver a culture of continuous improvement through the use of Lean Six Sigma. Teams will also be able to use this model to develop strategic action plans to improve the culture of continuous improvement within their institution. In addition, this paper explains the journey the authors have taken in creating this model by using a mixture of literature review, questionnaires and case studies to build the model and the use of test cases to refine and improve the model.

Design/methodology/approach
This paper uses a structured approach, focussing first on assessing the state of UK Lean Six Sigma (LSS) implementation and the, through the use of the case study method, the authors have designed a maturity model based on the classic capability maturity matrix approach. The final model has then been tested to refine the model into an improved version.

Findings
Key findings from interviewing the academic institutions that make up this paper highlight the current best practice in the UK and how far they still have to travel to become truly continuous improving organisations.

Research limitations/implications
This paper is limited to only focussing on UK institutions in the design and development of the maturity model. Future research should benchmark UK institutions more formally with international universities from North America and the Far East.

Practical implications
This paper present a final maturity model which can be used by academic leadership teams to both map their maturity at delivering continuous improvement projects and to act as an action plan to move the culture towards a quality-based, continuously improving institution.

Originality/value
To the best of the authors’ knowledge, this is the first such model to be produced focussing on the leadership and sustainability of deploying LSS in academic institutions.
Islamic stock-sukuk indexes' correlations: does financial uncertainty matter?
Authors: Alahouel Fatma , Loukil Nadia 
Published: January 2021

PurposeThis study examines co-movements between global Islamic index and heterogeneous rated/maturity sukuk. It tests the impact of financial uncertainty on these movements.Design/methodology/approachFirstly, we conduct a bivariate wavelet analysis to assess the co-movements between stocks and sukuk indexes. Secondly, we use General dynamic factor model and stochastic volatility to construct financial uncertainty index from Islamic stock indexes. Finally, we run regression analysis to determine the impact of uncertainty on the obtained correlations.FindingsOur results suggest the absence of flight to quality phenomenon since correlations are positive especially at a short investment horizon. There is evidence of contagion phenomena across assets. Financial uncertainty may be considered as a determinant of stock-sukuk co-movements. Our results show that a rise in financial uncertainty induces correlation to move in the opposite direction in the short term, (exception for correlation with AA-Rated sukuk). However, the sign of stock market uncertainty becomes positive in the long term, which leads sukuk and stocks to move in the same direction (exception for 1–3 Year and AA Rated sukuk).Practical implicationsInvestors may combine sukuk with 1–3 Year maturity and AA Rated when considering long holding periods. Further, all sukuk categories provide diversification benefit in time high financial uncertainty expectation for AA Rated sukuk when considering short holding periods.Originality/valueTo the best of our best knowledge, our study is the first investigation of the impact of financial uncertainty on Stock-sukuk co-movements and provides recommendation considering sukuk with different characteristics.

The paper suggests new research avenues to study alternative worldviews in organisations.Originality/valueThis paper creatively contributes to the discussion about alternatives to the current unsustainable economy with a special focus on the micro level, where businesses act as a vital driving force for economic growth.
Comparing the day temperature and holiday effects on retail sales of alcoholic beverages – a time-series analysis
Authors: Hirche Martin , Haensch Juliane , Lockshin Larry 
Published: January 2021

PurposeLittle research on the influence of external factors, such as weather and holiday periods, on retail sales on alcoholic beverages is available. This study aims to investigate how weekly retail sales of different alcoholic beverages vary in association with daily maximum temperatures and annual federal holidays across selected US counties in the years 2013 to 2015. The research provides information, which can contribute to better sales forecasts.Design/methodology/approachSecondary data of weekly retail sales (volume) of alcoholic beverages from 37,346 stores in 651 counties in the USA are analysed. The data cover on average 21% of all existing US counties and 12% of the total US off-trade retail sales of alcoholic beverages in the period studied (Euromonitor, 2017). Additional data of federal holidays and meteorological data are collated for each county in the sample. Seasonal autoregressive integrated moving average models with exogenous regressors (SARIMAX) are applied to develop forecasting models and to investigate possible relationships and effects.FindingsThe results indicate that off-trade retail sales of beer, liquor, red and white wine are temperature sensitive throughout the year, while contrary to expectations rosé, sparkling and other wines are not. Sales sensitivities to temperature also differ by geography. In the warmest regions, liquor and white wine sales do not respond to temperature changes, as opposed to the coolest regions, where they are responsive. Public holidays, particularly Easter, Thanksgiving, Christmas and New Year holidays, represent a constant influencing factor on short-term sales increases for all investigated alcoholic beverage categories.Originality/valueThis is the first large-scale study of weather and holiday-related sales variations over time, across geographies and different alcoholic beverage categories. Seasonal and non-seasonal short-term sales variations are important for retailers and manufacturers alike. Accounting for expected changes in demand accommodates efficiencies along the supply chain and has implications for retail management, as well as adjusting marketing efforts in competing categories.
CFD-based calculation method of convective heat transfer coefficient of spiral bevel gear in intermediate gearbox under splash lubrication
Authors: Lu Fengxia , Wang Meng , Liu Weizhen , Bao Heyun , Zhu Rupeng 
Published: January 2021

Purpose
This paper aims to propose a numerical method to calculate the convective heat transfer coefficient of spiral bevel gears under the condition of splash lubrication and to reveal the lubrication and temperature characteristics between the gears and the oil-air two-phase flow.

Design/methodology/approach
Based on computational fluid dynamics, the multiple reference frames (MRF) method was used to simulate the rotational characteristics of gears and the motions of their surrounding fluid. The lubrication and temperature characteristics of gears were studied by combining the MRF method with the volume of the fluid multiphase flow model.

Findings
The convective heat transfer coefficient can be improved by increasing the rotational speed and the oil immersion depth. Moreover, the temperature of the tooth surface having a large convective heat transfer coefficient is also found to be low. A large convection heat transfer coefficient could lead to a good cooling effect.

Originality/value
This method can be used to obtain the convective heat transfer coefficient values at different meshing positions, different radii and different tooth surface positions. It also can provide research methods for improving the cooling effect of gears under the condition of splash lubrication.

Has financial inclusion made the financial sector riskier?
Authors: Ozili Peterson Kitakogelu 
Published: January 2021

Purpose
This paper aims to examine whether high levels of financial inclusion is associated with greater financial risk.

Design/methodology/approach
The study uses regression methodology to estimate the effect of financial inclusion on financial risk.

Findings
The findings reveal that higher account ownership is associated with greater financial risk through high non-performing loans and high-cost inefficiency in the financial sector of developed countries, advanced countries and transition economies. Increased use of debit cards, credit cards and digital finance products reduced risk in the financial sector of advanced countries and developed countries but not for transition economies and developing countries. The findings also show that the combined use of digital finance products with increased formal account ownership improves financial sector efficiency in developing countries while the combined use of credit cards with increased formal account ownership reduces insolvency risk and improves financial sector efficiency in developing countries.

Research limitations/implications
The paper offers several implications for policy and financial regulation. It suggests policies that would reduce the financial risk that financial inclusion poses to the financial sector.

Originality/value
The recent interest in financial inclusion and the unintended consequences of policy-driven financial inclusion in some parts of the world is raising concern about the risks that financial inclusion may introduce to the formal financial sector. Little is known about the risks that financial inclusion may pose to the financial sector.
Assessing industrial barriers of additively manufactured digital spare part implementation in the machine-building industry: a cross-organizational focus group interview study
Authors: Chekurov Sergei , Salmi Mika , Verboeket Victor , Puttonen Tuomas , Riipinen Tuomas , Vaajoki Antti 
Published: January 2021

PurposeAlthough additive manufacturing (AM) has been demonstrated to have significant potential in improving spare part delivery operations and has been adopted to a degree in the aviation and automotive industries, its use in spare part production is still limited in other fields due to a variety of implementation barriers. The purpose of this article is to assess the significance of previously reported barriers in the context of the machine-building industry.Design/methodology/approachAdoption barriers are identified from the literature and formulated as hypotheses, which are verified with a set of focus group interviews consisting of original equipment manufacturers (OEMs), AM service providers and quality inspection and insurance institutions. The results of the interviews are reported qualitatively, and the transcripts of the interviews are subjected to quantitative content analysis.FindingsThe article identifies distrust in quality, insufficient material and design knowledge among stakeholders and poor availability of design documentation on spare parts as the key barriers of adopting AM in the production of spare parts. The three key barriers are interconnected and training engineers to be proficient in design and material issues as well as producing high-quality design documentation will yield the highest increase in AM implementation in spare parts.Originality/valueThe article offers a unique approach as it investigates the subjective views of a cross-organizational group of industrial actors involved in the machine-building industry. The article contributes to the theory of digital spare parts by verifying and rejecting presented barriers of AM implementation and how they are interconnected.
What makes people engage in civic activism on social media?
Authors: Hong Hyehyun , Kim Yeuseung 
Published: January 2021

PurposeGiven the profound impact of social media on civic activism, as demonstrated by the #BlackLivesMatter and #MeToo movements, the current study aimed to examine the factors that influence the public to engage in civic activism on social media platforms.Design/methodology/approachThis study used the responses from 4,316 social media users who participated in the 2018 American Trends Survey (Wave 35) conducted by Pew Research Center. The dataset was analyzed using hierarchical regression.FindingsThe results suggest that respondents who were younger, female, White and liberal were more likely to participate in activism-related behaviors, such as using hashtags, changing profile pictures and participating in groups with shared interests in political and social issues. Respondents' engagement in online civic activism increased particularly when they had a strong motive for expressing and sharing their opinions. In contrast, external online political efficacy – the belief that social media influences policymaking and decision makers – was not significantly associated with activism engagement on social media.Originality/valueThis study identified key demographic characteristics of social media users who participate in online civic activism. In addition, the findings extend previous lines of inquiry by examining and assessing the impact of external online political efficacy and opinion expression motive. We conclude that individuals engage in civic activism on social media mainly because they find it important to express views on political and social issues and to find others who share these views, as opposed to thinking that social media can be used to exert influence on policy decisions.
Rare cases of PAMI syndrome in both father and son with the same missense mutation in PSTPIP1 gene and literature review
Authors: Huang Xiaowen , Xu Meinian , Dai Siqi , Wang Menglei , Zheng Huanxin , Zeng Kang , Li Li 
Published: January 2021

AbstractPSTPIP1‐associated myeloid‐related proteinaemia inflammatory (PAMI) syndrome has been described as a rare and distinct clinical phenotype of PSTPIP1‐associated inflammatory diseases. We report PSTPIP1 mutation in both father and son who have leukopenia and acne‐like lesions. Through whole‐exome sequencing on blood DNA, it is found a heterozygous mutation of PSTPIP1 gene c.748G>A on the father and son. The diagnosis of PAMI is made based on DNA sequencing results and clinical characteristics of typical lesions, leukopenia, and the markedly increased serum S100A8/A9 (calprotectin).
Associations between testosterone and immune activity in alligators depend on bacteria species and temperature

Published: January 2021

Abstract

The immunocompetence handicap hypothesis (ICHH) postulates that testosterone supports the development of secondary sexual traits while simultaneously suppressing immune function, creating a trade‐off between trait quality and pathogen vulnerability.

The nature of interactions between testosterone and immunity is complex. Conflicting patterns from the literature suggest that testosterone–immunity relationships are variable across immune measures and may be modified by factors both intrinsic and extrinsic to the organism.

In this study, we tested the ICHH in free‐ranging American alligators Alligator mississippiensis and examined how both intrinsic (steroid hormone levels) and extrinsic (temperature) factors modulate the relationship between testosterone and immunity. Specifically, we quantified the simultaneous effects of testosterone and dehydroepiandrosterone (DHEA) on microbial killing capacity of three bacteria species (Escherichia coli, Salmonella typhimurium and Klebsiella pneumoniae) at two challenge temperatures (15°C and 30°C).

We found that accounting for circulating levels of DHEA was important for predicting testosterone‐mediated effects on microbial killing capacity. We also found that testosterone‐mediated immunosuppression was dependent on temperature and bacteria species, with negative effects of testosterone present only for S. typhimurium at 15°C.

Our results highlight the context dependency of interactions between testosterone and immunity, and illustrate the importance of evaluating the ICHH in natural systems to identify key intrinsic and extrinsic factors modulating testosterone‐immunity trade‐offs.

AbstractBackgroundImmune checkpoint inhibitors (ICIs) are an established treatment for non‐small cell lung cancer (NSCLC) that have demonstrated durable clinical benefits (DCBs). Previous studies have suggested NY‐ESO‐1 and LAG‐3 to be surrogate markers of ICI responses in NSCLC; therefore, we explored the predictive value of their expression in NSCLC.MethodsWe retrospectively reviewed the records of 38 patients with advanced NSCLC treated with anti‐PD‐1 monoclonal antibodies from 2013 to 2016 at Seoul National University Hospital and Seoul National University Bundang Hospital after failed platinum‐based chemotherapy. Tumor tissues from each patient were subjected to immunohistochemical analysis to determine NY‐ESO‐1, LAG‐3, and PD‐L1 expression, whose ability to predict progression‐free survival (PFS) and overall survival (OS) was then analyzed alongside their positive (PPV) and negative (NPV) predictive values.ResultsNY‐ESO‐1 or LAG‐3 expression was detected in all tumor samples from patients with high PD‐L1 expression and was significantly associated with favorable outcomes, unlike PD‐L1 expression. Patients with both NY‐ESO‐1‐ and LAG‐3‐expressing tumors had a high DCB rate and those with triple‐positive PD‐L1, LAG‐3, and NY‐ESO expression had a superior median OS and PFS than those with triple‐negative expression. Furthermore, LAG‐3 and NY‐ESO‐1 co‐expression was an independent predictor of both PFS and OS, while LAG‐3 displayed a good NPV.ConclusionsPatients with NSCLC who co‐express NY‐ESO‐1 or LAG‐3 with PD‐L1 exhibit greater DCBs and improved long‐term survival following anti‐PD‐1 therapy. Moreover, NY‐ESO‐1 and LAG‐3 could be novel predictive biomarkers of survival and should be considered in the future use of ICIs.
