Published: February 2022

ABSTRACTNatural hybrid zones provide opportunities for studies of the evolution of reproductive isolation in wild populations. Although several recent investigations have found that the formation of neo-sex chromosomes is associated with reproductive isolation, the mechanisms remain unclear in most cases. Here, we assess the contemporary structure of gene flow in the contact zone between largely allopatric cytotypes of the dioecious plantRumex hastatulus, a species in which there is evidence of sex chromosome turn-over. Males to the west of the Mississippi river, USA, have an X and a single Y chromosome, whereas populations to the east of the river have undergone a chromosomal rearrangement giving rise to a larger X and two Y chromosomes. Using reduced-representation sequencing, we provide evidence that hybrids form readily and survive multiple backcross generations in the field, demonstrating the potential for ongoing gene flow between the cytotypes. At the scale of chromosomes, cline analysis of each chromosome separately captured no signals of difference in cline shape between chromosomes. However, when comparing SNPs, principal component regression revealed a significant increase in the contribution of individual SNPs to inter-cytotype differentiation on the neo-X, but no correlation with recombination rate. Cline analysis revealed that the only SNPs with significantly shallower clines than the genome-average were located on the neo-X. Our data are consistent with a role for the neo-sex chromosome in reproductive isolation betweenR. hastatulus cytotypes. Our investigation highlights the importance of studying plant hybrid zones in species with sex chromosomes for understanding mechanisms of reproductive isolation and for understanding the role of gene flow in governing the spread of the neo-X chromosomes.

Authors: Gao Zhenhuan , Liu Yongxuan , Wang Chong , Yang Huisheng , Xu Lining , Qiao Lijie 
Published: February 2022

Purpose
This study aims to report the CO2 corrosion performance of 3Cr steel and 3Cr2Al steel and reveal the role of aluminum in mitigating corrosion of low-Cr steel.

Design/methodology/approach
Aluminum was added to 3Cr steel to prepare a new type of 3Cr2Al steel, and the effect of aluminum on the corrosion resistance of pipeline steel was studied using morphology observation and composition analysis, weight loss tests and electrochemical test.

Findings
In the CO2/O2 coexistence environment, the average corrosion rate of the 3Cr2Al steel was obviously lower than that of the 3Cr steel. The addition of aluminum expanded the range of prepassivation, and the dynamic potential polarization curve of 3Cr2Al steel showed duplex prepassivation phenomena. 3Cr steel underwent severe local corrosion, and 3Cr2Al steel underwent uniform corrosion. The addition of aluminum contributed to the formation of a dense corrosion product layer and greatly reduced the localized corrosion sensitivity.

Originality/value
The studies on CO2 corrosion of aluminum containing low-Cr steel are quite rare. This study clarifies the role of aluminum by comparing the corrosion behavior of 3Cr2Al and 3Cr steel. The effect of aluminum on the growth of corrosion product film was discussed, and the duplex prepassivation phenomena of Cr and Al were revealed.
Dark side consequences of cyberchondria: an empirical investigation
Authors: Khan Abdul Wahid , Pandey Jatin 
Published: February 2022

PurposeCyberchondria refers to the repeated and excessive search for health-related information online, associated with increased health anxiety. This paper utilizes the protection motivation theory to investigate the negative behavioral consequences of cyberchondria that pose health risks to users, such as trust in the physician, propensity to self-medicate, and therapy compliance.Design/methodology/approachThe data for the study were collected from a sample of 317 participants in India using an online survey and form. The analysis was conducted using structural equation modeling.FindingsCyberchondria negatively affects the trust in physician and positively affects the propensity to self-medicate. Trust in physician negatively affects the propensity to self-medicate and positively affects therapy compliance. Furthermore, trust in physician partially mediates the relationship between cyberchondria and the propensity to self-medicate and completely mediates the relationship between cyberchondria and therapy compliance. Cyberchondria has no direct significant effect on therapy compliance.Research limitations/implicationsResearchers need to examine other behavioral or psychological factors affected by the reduced trust in physicians due to cyberchondria.Practical implicationsPhysicians and health care providers should refocus on patients with cyberchondria and regain their trust through quality interactions and services. Policymakers may consider regulating online health information publication to set the standards of information quality and source. Websites and platforms publishing health information online should distinctly label verified information.Originality/valueThis study investigates the damaging effects of cyberchondria's behavioral consequences that pose health risks to users.
A meta-analysis of the impact of agricultural extension services
Authors: Ogundari Kolawole 
Published: February 2022

PurposeThis study aims to address two research questions. First, do the agricultural extension services have an impact on the potential outcomes considered in the primary studies, and to what extent? Second, how sensitive is the reported impact to the study-specific characteristics in the primary studies?Design/methodology/approachThe paper synthesizes 45 studies that assessed the causal impact of agricultural extension services published in 2004–2021, using meta-regression analysis. It considers three measures of effect sizes – Cohen’s, Hedges and principal correlation coefficient (PCC) – to standardize the reported impact of agricultural extension services in the primary studies.FindingsThe empirical results show that, on average, agricultural extension services have statistically significant and positive impacts on the potential outcomes identified in the primary studies. However, the magnitude of the impact is considered medium-sized. Other results show that the effect size estimates of agricultural extension services' impact significantly vary with the data type (cross-sectional data vs. panel data), research design (non-experimental vs. experimental design) and econometric methods employed in the primary studies.Practical implicationsOne can argue that the medium-sized impact we estimated indicates evidence of a moderate, weak relationship between agricultural extension services and the potential outcomes considered in the primary studies. This means that agricultural extension services need to be restructured in the current form to stimulate change in the agricultural sector globally. In addition, the sensitivity of effect sizes to study attributes (i.e. data types, research design and econometric methods) shows that researchers and academicians need to pay attention to these attributes to provide more reliable estimates for policy purposes.Originality/valueThis is the first study that attempts to shed light on the overall performance of agricultural extension services using a meta-regression analysis approach.
Millennials’ perceptions of artificial intelligence in hotel service encounters
Authors: Rauf Abdul , Zurcher Marius , Pantelidis Ioannis , Winbladh Johan 
Published: February 2022

Purpose
Artificial intelligence (AI) is increasingly becoming part of the hospitality industry. In times of staff shortages, AI used in the industry can have advantages, but it also brings with it the possibility of customer backlash. The purpose of this paper is to understand the potential response of millennial guests to the potential applications of AI in the hotel industry. The emphasis was on which hotel service encounter categories are most suited to replacing employees with AI in the context of the millennial guest experience.

Design/methodology/approach
This quantitative research used a survey questionnaire for the data collection. Responses from 169 millennials from six continents were analysed using a combination of descriptive statistics, t-tests, MANOVA tests and Bonferroni tests.

Findings
Four service encounter categories were studied: (i) “Check-in”, (ii) “Reception Services (excl. check-in)”, (iii) “Wellness” and (iv) “Food and Beverage Services”. The results showed that of these four categories, “Food and Beverage Services” is more suited to replacing employees with AI than “Wellness”.

Practical implications
The findings of this research are important as they contribute to the body of knowledge related to the implementation of AI in the hospitality industry and provide useful information to policymakers and hotel managers who may wish to identify suitable areas for investment related to AI in their operations.

Originality/value
This study offers useful insight on a cutting-edge topic of AI application for service encounters within the hospitality sector and confirms the suitability of some encounters.
Running up the hill – long-term streaming video pilots: process, analysis and outcomes
Authors: Foster Anita K. , Springs Gene R. 
Published: February 2022

Purpose
Academic libraries are struggling to support the growing demand for streaming video. The purpose of this paper is to detail the experience of running three long-term pilots with different streaming video platforms, including processes involved, lessons learned and next steps.

Design/methodology/approach
This paper uses a mixed methods approach, combining analysis of usage data with case study observations.

Findings
The length of the pilots allowed for deep understanding of the needs of this academic library’s community’s engagement with streaming video in the classroom, and confirmed anecdotal information that availability of multiple platforms supports diverse needs which led to continuing access to all platforms, operationalized to be managed within existing processes. Using usage data and feedback from a task force led to decisions to continue with all three platforms that were piloted.

Research limitations/implications
While this research describes the experience at one academic library, the information may be generalizable enough that other libraries may use it for their streaming video collection development decisions.

Originality/value
Long-term pilot studies for streaming video platforms can be challenging for many libraries to undertake. With a modest initial financial commitment, the library was able to explore how the community might use streaming video. Through analysis of usage data, the library was able to see when, where and what was being used and could make better informed decisions about where to concentrate future funds for streaming video support.
Gain or loss: the double-edged effect of empowering leadership on employees’ innovative behaviours
Authors: Li Zhengwei , Qiu Chenye , Zeng Kai , Wang Feirong 
Published: February 2022

PurposeEmpowering leadership is often considered unequivocally positive for employees, but recent studies have shown that this ostensibly straightforward effect is more complex. The dual facets of the effect of empowering leadership – especially on employees’ innovative behaviour – have received insufficient attention. Based on job demand-resource (JD-R) theory, this study aims to propose a theoretical framework for the relationship between empowering leadership and employees’ innovative behaviours with a dual process model of gain and loss.Design/methodology/approachThis study is survey based, with 261 paired leader–employee data points collected in the People’s Republic of China.FindingsThe results show that empowering leadership has a “double-edged” effect on employees’ innovative behaviours: it affects innovative behaviours positively through employee job engagement and negatively through emotional exhaustion. Moreover, trust in leaders moderates the mediating roles of job engagement and emotional exhaustion.Originality/valueThis study contends that empowering leadership has a dual impact on employees and proposes a promising model of this double-edged effect to contrast with other complex models in the empowering leadership literature. Furthermore, this study uses JD-R theory to deeply explore the dual process whereby empowering leadership influences employees’ innovative behaviour and provides practical guidance for business management.
Whose fault is it? Loan defaults at the Devkhand bank, India
Authors: Joshi Gaurav 
Published: February 2022

Learning outcomes
Through this case, the students will be able: to study how developments in the external environment impact businesses, in general, and banking sector, in particular, banks/banking, environmental management, financing/borrowing, government, political business risk and politics; to identify the politico-legal constituents of the external environment which significantly influence businesses; and to analyse the pros and cons of loan-waivers as a policy decision on various stakeholders including banks, borrowers, governments as well as the larger society.

Case overview/synopsis
The case is symptomatic of the dilemmas faced by the Indian bank employees, in charge of loan-disbursals, torn between seemingly contradictory demands from their top management and the governments.

Complexity academic level
The case is meant to be used in the course on “Business Environment” both at the UG and PG levels. It can be used along with the module on “External Environment and its Constituents” to augment students’ understanding of the “Impact of Political Environment on Business.” The case can also enrich the class discussion on the PEST (politico-legal/economic/socio-cultural/technological) framework for analysing the forces in the external environment acting upon a business.

Big data analytics in strategic sales performance: mediating role of CRM capability and moderating role of leadership support
Authors: Chatterjee Sheshadri , Chaudhuri Ranjan , Vrontis Demetris 
Published: February 2022

PurposeThis study investigates how the combined effects of big data ability and CRM capability could impact on an organization's strategic sales performance (SSP), and how the leadership support (LS) could moderate the relationships between SSP with CRM capability and customer retention ability.Design/methodology/approachHaving inputs from the literature and resource-based view (RBV) theory, a model has been developed conceptually. The conceptual model was validated statistically using the partial least squares structural equation modeling (SEM) technique with 317 responses.FindingsThe study found that organizations' big data analytics (BDA) capability, along with customer relationship management (CRM) capability, positively and significantly impacts organizations' SSP. Also, the study found that LS has a moderating impact on organizations' SSP.Research limitations/implicationsThe study cannot be generalizable, as it is cross-sectional in nature. Also, the sample size for statistically validating the model is 317, which is not large enough to generalize the study findings. The study has used only five constructs and one moderator. With more constructs and other moderators, the boundary conditions of the model could have been increased, which could result a better explanative power of the model.Practical implicationsThis study shows that organizations' big data and CRM capabilities are important for their SSP; therefore, managers must ensure that their organization has appropriate big data and CRM capabilities. Also, the study shows the significance of LS to increase the SSP of their organizations. Thus, organizational leadership must support big data and CRM-related capabilities and ensure employees are appropriately trained to successfully use these capabilities.Originality/valueOnly a limited number of studies are available on the combined impact of big data capability and CRM capability on an organization's strategic sales. How BDA could help organizations to improve their SSP has not been explicitly studied. The proposed model shows that these capabilities, along with the moderating effects of LS, impact on organizations' SSP. Thus, the proposed theoretical model is a unique model, and the study is novel.
Exploring factors influencing bicycle-sharing adoption in India: a UTAUT 2 based mixed-method approach
Authors: Chopdar Prasanta Kr , Lytras Miltiadis D. , Visvizi Anna 
Published: February 2022

PurposeBicycle sharing offers a novel way to create smart and sustainable mobility solutions for the future. The purpose of this study is to draw on the Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2) framework for identifying the factors necessary to predict bike-sharing intention among users in India.Design/methodology/approachData were collected through a questionnaire distributed across four major cities in India, and 515 responses were analyzed. A sequential approach was employed to analyze the data using Partial Least Square–Structural Equation Modeling (PLS-SEM) and Fuzzy-set Qualitative Comparative Analysis (fsQCA).FindingsThe findings from PLS analysis revealed that performance expectancy, effort expectancy, facilitating conditions, hedonic motivation and price value are the salient variables that affect users' intentions to participate in bike sharing. In addition, based on fsQCA, six configurations of causal conditions are presented as intermediate solutions that produce the same results. Although antecedent conditions, such as habit and social influence, had an insignificant effect on individuals' BSI, they create conditions sufficient to encourage users' participation in bike sharing in combination with other variables.Research limitations/implicationsA few limitations of this research and the implications of the findings in terms of theory and policy implications are also discussed.Originality/valueThe reported study is one of the earliest to explain bike-sharing adoption in India using the UTAUT 2 model.
Toward higher import substitution: does quality governance matter for uptake and pricing of improved local rice in Ghana?
Authors: Ibrahim Latif Apaassongo , Sakurai Takeshi , Tachibana Towa 
Published: February 2022

PurposeProduct quality standardization is the solution to market collapses due to quality-insensitive pricing regimes prevalent in West African (WA) rice value chains. However, access to local rice that is differentiated by quality standards is limited. This paper explores feasibility of quality standardization of local rice and evaluates how its price–quality connecting effect depends on retailer characters/reactions.Design/methodology/approachThis study uses panel data from a wholesale randomized control trial (RCT) and three surveys of 135 rice retailers in Ghana.FindingsImproved local food value chains and access to quality differentiated products are impactful entry points for import substitution policies. The strength of interretailer competition, retail infrastructure and wholesaler activities matter for a stronger connection of prices and quality, given uptake of quality-standardized local rice.Research limitations/implicationsAccess to quality-differentiated local rice can be increased via private and third-party certification. This addresses the prevailing inefficient pricing and its related problems. The positive impacts of such access would be magnified by designing quality certification interventions to elicit regular-frequent purchases by retailers and target retailers with adequate retail infrastructure in high competition areas. However, this study only explored profitability and opportunities for strategic behavior as the behavioral basis for quality-sensitive pricing. Other impact mechanisms could be explored in further research that includes consumer data.Originality/valueDespite their difficulty and limited use in value chains studies, RCT and panel data methods are used. This study is the first to empirically analyze feasibility of introducing product standardization, a missing institution in the WA local rice markets.

PurposeThe shutdown of normal face-to-face educational method of learning caused by the coronavirus disease 2019 (COVID-19) pandemic has made the education stakeholders reconsider and rethink education anew in light of the emerging challenges and opportunities imposed on e-learning in higher education in Nigeria post COVID-19. This study investigates the challenges confronting e-learning in higher education in Nigeria amid COVID-19.Design/methodology/approach Drawing upon data collected through a structured questionnaire administered to 395 lecturers in various disciplines in private, state and federal universities in Nigeria, the study adopts a quantitative research method. The quantitative data were analyzed using descriptive statistics.FindingsThe findings indicate that Nigeria Higher Education Institutions (HEIs) are still in the early stage of adopting the e-learning mode of study. In addition, there was no existing e-learning curriculum before the pandemic. Also, adopting e-learning mode of teaching was an uphill task for both the lecturers and the learners, given the lack of experience in information and communications technology usage and inadequate infrastructure to support e-learning.Research limitations/implications A major limitation of the study is the inability to investigate the challenges facing students in using e-learning tools due to the unavailability of access to students during the lockdown. However, the limitations create opportunities for further studies into the subject matter.Originality/value The study is timely given that HEIs in Nigeria and some other countries in Africa are yet to adopt blended teaching methods. Literature reveals that most HEIs in Nigeria are using only brick and mortar mode of teaching despite the benefit of blended learning in a pandemic situation.
