Modelling searching on academic social networking sites: a focus on learning outcomes
Authors: Wu Dan , Lu Liuxing , Cheng Lei 
Published: May 2022

Purpose
This paper aims to establish a theoretical search model on academic social networking sites (ASNSs).

Design/methodology/approach
Based on the characteristics of ASNSs and a previous extended sense-making model, this paper first presented an initial model of searching on ASNSs. Next, an online survey was conducted on ResearchGate to understand the search processes and outcomes with the help of a survey questionnaire. In total, 359 participants from 70 countries participated in this online survey. The survey results provided a basis for modifying the initial model.

Findings
Results showed that the theoretical model of searching on ASNSs included motives for searching on ASNSs, identification of needs, search triggered by information needs, search triggered by social needs and outcomes. The search triggered by information needs was significantly positively correlated with learning outcomes. Besides learning outcomes, searching on ASNSs could help user amplify their social networks and promote research dissemination.

Practical implications
Understanding users’ search habits and knowledge acquisition can provide insights for ASNSs to design an interface to support searching and enhance learning. Moreover, the proposed model can help users recognize their knowledge status and learning effects and improve their learning efficiency.

Originality/value
This paper contributes to establishing a theoretical model to understand users’ search process and outcomes on ASNSs.
“Konnichiwa, Mr. Robot”: a direct observation of hotel visitors' attitudes and anxiety regarding service robots
Authors: Leung Rosanna 
Published: May 2022

PurposeThis study investigates human behavior, specifically attitude and anxiety, toward humanoid service robots in a hotel business environment.Design/methodology/approachThe researcher adopted direct observations and interviews to complete the study. Visitors of Henn-na Hotel were observed and their spatial distance from the robots, along with verbal and non-verbal behavior, was recorded. The researcher then invited the observed hotel guests to participate in a short interview.FindingsMost visitors showed a positive attitude towards the robot. More than half of the visitors offered compliments when they first saw the robot receptionists although they hesitated and maintained a distance from them. Hotel guests were also disappointed with the low human–robot interaction (HRI). As the role of robots in hotels currently remains at the presentation level, a comprehensive assessment of their interactive ability is lacking.Research limitations/implicationsThis study contributes to the HRI theory by confirming that people may treat robots as human strangers when they first see them. When a robot's face is more realistic, people expect it to behave like an actual human being. However, as the sample size of this study was small and all visitors were Asian, the researcher cannot generalize the results to the wider population.Practical implicationsCurrent robot receptionist has limited interaction ability. Hotel practitioners could learn about hotel guests' behavior and expectation towards android robots to enhance satisfaction and reduce disappointment.Originality/valuePrior robot research has used questionnaires to investigate perceptions and usage intention, but this study collected on-site data and directly observed people's attitude toward robot staff in an actual business environment.

Authors: Hussainey Khaled , Albitar Khaldoon , Alkaraan Fadi 
Published: May 2022

Purpose
This paper aims to provide early evidence on corporate transformation towards Industry 4.0 (CTTI4) in the UK, particularly by examining the effect of corporate governance on the narrative reporting of CTTI4.

Design/methodology/approach
The authors analyse all UK financial times stock exchange all-share non-financial firms that have published their annual reports for the period of 2013–2018. The authors use computerised textual analysis to measure the level of corporate reporting on Industry 4.0 (I4.0) for 1,001 firm-year observations. The authors used different regression models to test the research hypotheses.

Findings
The findings contribute to the growing literature on business model transformation in UK companies towards the I4.0 strategy. The findings show that the level of reporting on CTTI4 is improving over the sample period and varies between industries. The authors also find that better governance quality enhances the level of reporting on CTTI4.

Practical implications
The findings of this study inform decision makers and regulators about factors driving UK companies to report information about their actionable strategies to direct I4.0 endeavours.

Originality/value
The paper makes an important and novel contribution to corporate disclosure literature. So far as the authors know, it is the only paper to examine the impact of corporate governance on corporate narrative reporting on I4.0 technologies. Moreover, to the best of the authors’ knowledge, it is the first paper to show that the quality of corporate governance adds value to this strategic type of corporate disclosure.
The impact of supply chain relationship configurations on supplier performance: investigating buyer–supplier relations in the aerospace industry
Authors: Schmelzle Ulrich , Mukandwal Prabhjot S. 
Published: May 2022

Purpose A supplier may sell not only to one buyer (sole relationship configuration) but also to the buyers competitors (shared relationship configuration) for a specific product category. This study examines the performance implications when suppliers establish shared relationships with the buyer’s competitors.Design/methodology/approach Secondary data are used to test hypotheses relating a supplier’s relationship configurations to its operational performance. A seemingly unrelated regression approach (SUR) is applied to analyze the data, followed by endogeneity checks of the empirical findings.Findings The study shows that suppliers with less-shared ties with buying firms’ competitors exhibit superior inventory efficiency and asset turnover. Thus, suppliers can improve operational efficiency by creating relatively exclusive, deep and trust-based relations instead of more extensively shared and shallower relationships.Research limitations/implications Based on agency theory as a theoretical lens and aerospace industry data, this research contributes by addressing the supplier’s perspective and linking its operational efficiency performance with its chosen supply relationship configuration.Practical implications Suppliers need to understand the performance implications of choosing relatively exclusive relationships versus shared relationships with buying firms. The research provides new insights for managers and can guide their supply chain decision-making.Originality/value Little is known about how a supplier’s relationship configurations can elevate, or impair, its operational efficiency. While conventional wisdom holds that suppliers should focus on multiple avenues of revenue growth by selling to buyers’ competitors, this study demonstrates that more sales to a buying firm’s rivals might, in fact, reduce a supplier’s efficiency.
The development of the Chinese wine industry and trade
Authors: Mizik Tamás , Balogh Jeremiás Máté 
Published: May 2022

Purpose
The study aims to give an overview of the development of the Chinese wine industry and trade between 1992 and 2019. Its importance is highlighted by the fact that China has become one of the world’s largest wine-consuming markets with great growth potential and is now ranked among the top 10 largest global markets for wine.

Design/methodology/approach
To address Chinese wine industry competitiveness, revealed comparative advantage (RCA), relative trade advantage (RTA) and revealed competitiveness (RC) were calculated, based on the World Bank World Integrated Trade Solution database. Chinese wine market-related issues are analyzed by Porter’s Five Forces in help of Market Line industry profile reports.

Findings
Results suggest that the Chinese wine market is relatively fragmented, with a concentrated food and beverages retail industry, strong buyer power and a moderate supplier power. The RCA calculated for the Chinese wine trade indicates that the share of exported bottled wine has become significant in the analyzed period. However, the RCA was perceivable just for bottled wines and only in the last analyzed period (2013–2019), whereas RTA and RC were negative for all periods revealing a comparative disadvantage. However, current market trends suggest that they will increase in the future.

Research limitations/implications
Data accuracy may affect these results because wine statistics may contain mislabeling. Moreover, China expanded its investments in many well-known wine regions all over the world, especially in Bordeaux, France. These, along with the significant re-export, could make it harder to interpret wine trade data because some part of the export is related to Chinese wineries outside of China.

Practical implications
Knowing the above-mentioned limitations, results should be interpreted with caution. However, high-quality wines can be identified as a niche market in China.

Originality/value
The study provided a detailed analysis of the Chinese wine industry and its competitiveness.
The impact of COVID-19 on conventional and Islamic stocks: empirical evidence from Pakistan
Authors: Bhutto Niaz Ahmed , Khan Shabeer , Khan Uzair Abdullah , Matlani Anjlee 
Published: May 2022

PurposeThe purpose of this study is to investigate the impact of COVID-19 on conventional and Islamic stocks by using the data spanning from February 25, 2020, to February 3, 2021, and employing a panel regression approach.Design/methodology/approachIn this study a panel regression approach has been used.FindingsThe study finds a negative association between COVID-19 and stock (both Islamic and conventional). After splitting the data into 1st and 2nd waves, the relationship between COVID-19 and stock (both Islamic and conventional) remains the same (negative) in the case of the 1st wave. In contrast, in the case of the 2nd wave, the relationship turned out to be positive. During both waves of the pandemic, the magnitude of the effect is found to be higher for conventional stocks. Additionally, the study also analyzes the aggregate influence of COVID-19 on different sectors and finds that commercial banks, oil and gas exploration and marketing companies are the most influenced sectors. At the same time, automobiles and pharma are the least affected sectors.Practical implicationsThe study suggests that markets start gaining momentum to reach their prepandemic level after absorbing the initial shock (emergence of a pandemic). The study also provides thorough insights for market regulators and policymakers by implying the dynamic relations between markets (conventional and Islamic) and financial crisis, which would allow them more effective control of crisis in future endeavors.Originality/valueThis is one of the first studies to investigate the impact of COVID-19 on both conventional and Islamic stocks, especially in the context of Pakistan.
CEO polychronicity and SME internationalization
Authors: Agnihotri Arpita , Bhattacharya Saurabh 
Published: May 2022

PurposeThis study, leveraging the upper echelon and social network theories, aims to explore the association between chief executive officers (CEO’s) polychronicity and small and medium size enterprises (SMEs’) international performance under the complete mediation effect of social networks. The paper explores this relationship under the moderation effect of CEO perceived time pressure and synchrony preference.Design/methodology/approachThe paper investigates a moderated mediating relationship based on a sample of 186 UK firms.FindingsThe findings of this study suggest that social network fully mediates the CEO polychronicity and firm international performance relationship. Furthermore, CEO perceived time pressure moderates the social network and SME international performance relationship such that it reduces the positive indirect association between CEO polychronicity and SME international performance. CEO synchrony preference, on the contrary, enhances the positive indirect association between CEO polychronicity and SME performance.Originality/valueExtant research suggests SMEs having a more robust set of organizational capabilities helps them network and avail foreign market knowledge. However, research exploring antecedents of this organizational capability is scant.
Feedbacks between size and density determine rapid eco‐phenotypic dynamics
Authors: Gibert Jean P. , Han Ze‐Yi , Wieczynski Daniel J. , Votzke Samantha , Yammine Andrea 
Published: May 2022

AbstractBody size is a fundamental trait linked to many ecological processes—from individuals to ecosystems. Although the effects of body size on metabolism are well‐known, the potential reciprocal effects of body size and density are less clear. Specifically, (a) whether changes in body size or density more strongly influence the other and (b) whether coupled rapid changes in body size and density are due to plasticity, rapid evolutionary change or a combination of both.Here, we address these two issues by experimentally tracking population density and mean body size in the protistTetrahymena pyriformisas it grows from low density to carrying capacity. We then use Convergent Cross Mapping time series analyses to infer the direction, magnitude and causality of the link between body size and population dynamics. We confirm the results of our analysis by experimentally manipulating body size and density while keeping the other constant. Last, we fit mathematical models to our experimental time series that account for purely plastic change in body size, rapid evolution in size, or a combination of both, to gain insights into the processes that most likely explain the observed dynamics.Our results indicate that changes in body size more strongly influence changes in density than the other way around, but also show that there is reciprocity in this effect (i.e., a feedback). We show that a model that only accounts for purely plastic change in size most parsimoniously explains observed, coupled phenotypic and ecological dynamics.Together, these results suggest (a) that body size can shift dramatically through plasticity, well within ecological timescales, (b) that rapid changes in body size may have a larger effect on population dynamics than the reverse, but (c) phenotypic and population dynamics influence each other as populations grow. Overall, we show that rapid plastic changes in functional traits like body size may play a fundamental—but currently unrecognized—role in familiar ecological processes such as logistic population growth.Read the freePlain Language Summaryfor this article on the Journal blog.

SummaryBackground and AimsCurrent guidelines recommend long‐term nucleot(s)ide analogue (NA) therapy for patients with HBeAg‐negative chronic hepatitis B (CHB). However, disease remission has been described after stopping NA therapy, as well as HBsAg loss.MethodsWe performed a prospective multi‐centre cohort study of stopping NA therapy. Inclusion criteria were HBeAg‐negative CHB, the absence of cirrhosis and HBVDNA<lower limit of quantification for ≥18 months. We assessed virological and biochemical outcomes including HBsAg loss, as well as NA restart rates, over 96 weeks.ResultsIn total, 110 patients [62% entecavir (ETV); 28% tenofovir (TDF), 10% other] were enrolled. Median age was 56 years, 57% were male, 85% were Asian, median baseline HBsAg level was 705 (214–2325) IU/ml. Virological reactivation occurred in 109/110 patients, median time to detection was 8 (4–12) weeks, and occurred earlier after stopping TDF versus ETV (median 4 vs. 12 weeks p < 0.001). At week 96, 77 (70%) remained off‐treatment, 65 (59%) had ALT <2× ULN, 31 (28%) patients were in disease remission with HBVDNA <2000 IU/ml plus ALT <2× ULN and 7 (6%) patients had lost HBsAg. Baseline HBsAg ≤10 IU/ml was associated with HBsAg loss (6/9 vs. 1/101 p < 0.001). ALT >5× ULN occurred in 35 (32%); ALT flares were not associated with HBsAg loss. There were no unexpected safety issues.ConclusionVirological reactivation was very common after stopping NA therapy and occurred earlier after stopping TDF versus ETV. The majority of patients had ALT <2× ULN at week 96, but only one‐third achieved disease remission and HBsAg loss was rare. Very low HBsAg levels at baseline were uncommon but predicted for HBsAg loss and disease remission.

AimsTo investigate the influence of pharmacogenetic polymorphisms on efavirenz (EFV) exposure and metabolism in HIV‐infected Brazilians under treatment with EFV‐containing antiretroviral (ART) regimens.MethodsHIV‐positive adults (n = 82) on stable ART regimens containing 600 mg EFV once daily for at least 6 months were recruited at 2 university hospitals. Blood samples collected at mid‐dose interval were used to quantify the plasma concentrations of EFV (denoted [EFV]), its major metabolite 8‐OH‐EFV ([8‐OH‐EFV]) and [8‐OH‐EFV]/[EFV] metabolic ratio, and to genotype single nucleotide polymorphisms in CYP2B6 (rs3745274, c.516G > T; rs28399499, c.983 T > C) and ABCB1 (rs3842, c.4036G > A). CYP2B6 metabolic phenotypes were inferred from the CYP2B6 diplotypes. Linear regression modelling was applied to identify sociodemographic, clinical and pharmacogenetic predictors of [EFV] and [8‐OH‐EFV]/[EFV] metabolic ratio.ResultsWide (50‐fold) interindividual variation in [EFV], [8‐OH‐EFV] and [8‐OH‐EFV]/[EFV] was observed; 69.5% of participants had [EFV] within the nominal therapeutic range (1000–4000 ng/mL), while 19.5 and 11.0% had [EFV] below and above this range, respectively. Multiple regression modelling retained only CYP2B6 metabolic phenotypes or the combined rs3745274 and rs28399499 genotypes, as significant predictors of [EFV] and [8‐OH‐EFV]/[EFV].ConclusionEFV exposure and disposition varied widely among HIV‐infected Brazilians under stable treatment with EFV‐containing ART regimens. About 1/10 of the participants had [EFV] exceeding nominal supratherapeutic concentration (4000 ng/mL), but reported tolerance to the ARV regimens, while 1/5 of participants had nominal subtherapeutic [EFV] (<1000 ng/mL) but adequate virological response. Genotype for the 2 CYP2B6 single nucleotide polymorphisms studied explained 48% of variation in [EFV] and 35% of variation in [8‐OH‐EFV]/[EFV].
From pity to numbness: Social exclusion moderates the relationship between trait empathy and bystanders’ aggressive tendencies in cyberbullying
Authors: Gao Lu , Liu Cheng‐Hong , Yin Xian‐Rui 
Published: May 2022

AbstractStudies on cyberbullying have revealed an inconsistent relationship between trait empathy and bystanders’ aggressive tendencies towards victims. We believe that these studies have overlooked the role of social exclusion. We infer that high‐severity social exclusion suppresses the negative relationship between trait empathy and bystanders’ aggressive tendencies. In Study 1, 226 participants read a news report concerning a singer's humiliation by netizens due to lack of talent. The results revealed that trait empathy predicted lower aggressive tendencies towards the singer for participants with fewer experiences of social exclusion. However, trait empathy was unrelated to aggressive tendencies for participants with more experiences of social exclusion. In Study 2, 146 participants were randomly assigned to a low‐severity or a high‐severity social exclusion condition and were required to recall their experiences of low‐ or high‐severity social exclusion, respectively. The results demonstrated that in the low‐severity condition, trait empathy was negatively associated with participants’ aggressive tendencies towards the singer and this relationship was mediated by state empathy. However, there was no evidence that the process was at work in the high‐severity condition. This study further presents implications and directions for future research.
Optimal Allocation of Finite Sampling Capacity in Accumulator Models of Multialternative Decision Making
Authors: Ramírez‐Ruiz Jorge , Moreno‐Bote Rubén 
Published: May 2022

AbstractWhen facing many options, we narrow down our focus to very few of them. Although behaviors like this can be a sign of heuristics, they can actually be optimal under limited cognitive resources. Here, we study the problem of how to optimally allocate limited sampling time to multiple options, modeled as accumulators of noisy evidence, to determine the most profitable one. We show that the effective sampling capacity of an agent increases with both available time and the discriminability of the options, and optimal policies undergo a sharp transition as a function of it. For small capacity, it is best to allocate time evenly to exactly five options and to ignore all the others, regardless of the prior distribution of rewards. For large capacities, the optimal number of sampled accumulators grows sublinearly, closely following a power law as a function of capacity for a wide variety of priors. We find that allocating equal times to the sampled accumulators is better than using uneven time allocations. Our work highlights that multialternative decisions are endowed with breadth–depth tradeoffs, demonstrates how their optimal solutions depend on the amount of limited resources and the variability of the environment, and shows that narrowing down to a handful of options is always optimal for small capacities.
