Authors: Zhu Junchao , Wei GuangCheng , Zong Chen , Xin DaKuan 
Published: May 2023

Purpose
This paper aim to take the ship shaft stern bearing as the research object, and studies the influence of journal axial vibration on bearing dynamic characteristics under different misaligned angles and rotation speeds.

Design/methodology/approach
Computational fluid dynamics (CFD) and harmonic excitation method were used to build bearing unstable lubrication model, and the dynamic mesh technology was used in calculation.

Findings
The results indicate that journal axial vibration has a significant effect on bearing dynamic characteristics, like maximum oil film pressure, bearing stiffness and damping coefficients, and the effect is positively correlated with journal misaligned angle. The effect of shaft rotation speed and journal axial vibration on bearing dynamics characteristics are independent; they have no coupling. Bearing axial stiffness is mainly affected by the journal axial displacement, bearing axial damping is mainly affected by journal axial velocity and they are positively correlated with the misaligned angle. The influence of rotational speed on bearing axial stiffness and axial damping is not obvious.

Originality/value
This paper establishes the bearing dynamic model by CFD and harmonic excitation method with consideration of cavitation effect and analyzing the influence of journal axial vibration on the dynamic characteristics. The results are benefit to the design of ship propulsion shaft and the selection of stern bearing. Also, they are of great significance to improve the operation stability of the shaft bearing system and the vitality of the ship.

Homefluencers' endorsement of millennial consumers' purchase intention in new normal
Authors: Ghosh Mollika , Islam ABM Shahidul 
Published: May 2023

PurposeThe purpose of this study is to examine how “homefluencers” sponsored posts on millennial consumers' purchase intention in the international marketing sphere can be impacted in the new normal by drawing on source credibility, parasocial interaction (PSI) and persuasion knowledge model (PKM) theory.Design/methodology/approachThis research applies structural equation modeling (SEM) and mediation analysis as the data analysis method using non-probability purposive sampling of a total of 217 local millennial Instagram and Facebook users, who have followed homefluencers sponsored posts in fashion-beauty, yoga-fitness and food sectors.FindingsBased on hypothesis testing, advertising recognition strongly mediates purchase intention with the indirect effects of expertise and trustworthiness than attractiveness.Research limitations/implicationsThis research extends the international marketing literature on source credibility, PSI, PKM and purchase intention theory in the new normal by proposing “Homefluencer's Endorsement Model for Purchase Intention” (HEMPI). Specifically, the mediating role of ad recognition of homefluencers sponsorship disclosure (#paidad, #sponsored), positively affects “change-of-persuasion meaning” on Instagram and Facebook, where research is rare.Practical implicationsThis research provides valuable suggestions for global brand owners, consumers and authorities of Instagram and Facebook to consider post-COVID consumer behavior highlighting homefluencers sponsored collaboration.Originality/valueThe authors have contributed to the use of the source credibility model and PSI to identify the antecedents in determining how the homefluencer's effective sponsorship disclosure can positively activate ad recognition on millennial consumers' purchase intention in a crisis period from an international standpoint with the practical implications in post-COVID.
Parental influences on excessive Internet use among adolescents
Authors: O'Reilly Conor , Mohan Gretta 
Published: May 2023

PurposeUsing longitudinal data, this study aims to provide a greater understanding as to how parenting factors, including the employment of various disciplinary techniques, during a young person's early adolescence may contribute to excessive Internet use (EIU) in later adolescence.Design/methodology/approachEmploying “Problem Behaviour” theory (PBT) as a guiding framework, this study uses data from the Growing Up in Ireland ’98 Cohort to investigate the effect of proximal and distal parental influences, measured when children were 13 years old, on symptoms of EIU in young adults at 17 or 18 years. Multiple regression models control for other child and family factors, and separate models for males and females examine sex differentials.FindingsEstimation did not find a statistically significant association between internet-specific mediation practices in early adolescence and EIU in later adolescence. However, regularly playing games or sports together is a protective factor. Parent-adolescent conflict and spending time home alone are estimated as risk factors. How parents deal with misbehaviour is a strong predictor of EIU, with the direction of association dependent upon the type and frequency of discipline employed.Practical implicationsThe findings are of practical significance in informing parents of modifiable aspects of their behaviour that can lead to EIU.Originality/valueThe study applies a longitudinal modelling framework and considers the effect on EIU of various parental disciplinary techniques, representing a novel contribution.
New challenges for public value and accountability in the age of big data: a bibliometric analysis
Authors: Pavone Pietro , Ricci Paolo , Calogero Massimiliano 
Published: May 2023

Purpose
This paper aims to investigate the literacy corpus regarding the potential of big data to improve public decision-making processes and direct these processes toward the creation of public value. This paper presents a map of current knowledge in a sample of selected articles and explores the intersecting points between data from the private sector and the public dimension in relation to benefits for society.

Design/methodology/approach
A bibliometric analysis was performed to provide a retrospective review of published content in the past decade in the field of big data for the public interest. This paper describes citation patterns, key topics and publication trends.

Findings
The findings indicate a propensity in the current literature to deal with the issue of data value creation in the private dimension (data as input to improve business performance or customer relations). Research on data for the public good has so far been underestimated. Evidence shows that big data value creation is closely associated with a collective process in which multiple levels of interaction and data sharing develop between both private and public actors in data ecosystems that pose new challenges for accountability and legitimation processes.

Research limitations/implications
The bibliometric method focuses on academic papers. This paper does not include conference proceedings, books or book chapters. Consequently, a part of the existing literature was excluded from the investigation and further empirical research is required to validate some of the proposed theoretical assumptions.

Originality/value
Although this paper presents the main contents of previous studies, it highlights the need to systematize data-driven private practices for public purposes. This paper offers insights to better understand these processes from a public management perspective.
How value drivers of internet medical business model affect value creation: a configurational approach
Authors: Jiang Jihai , Liu Rui , Wang Fengquan 
Published: May 2023

PurposeThis paper aims to investigate how value drivers of internet medical business model affect value creation through a configurational approach. The internet medical business model (IMBM) is such a business model that integrates online and offline medical services with the driving force of internet technologies covering prediagnosis, in-diagnosis and postdiagnosis. The outbreak of COVID-19 and the support of national policies have boosted the development of internet health care. However, there are still many challenges in practice, such as the unclear innovation path, as well as difficulties in landing and profiting. Academic research has not yet provided sufficient theoretical insights. Therefore, to better explain and guide practice, it is urgent to clarify the innovation path and mechanism of value creation for IMBM.Design/methodology/approachBased on the sample of 58 internet medical firms in China, this paper adopts fuzzy-set qualitative comparative analysis (fsQCA) to explore the configurational effects of IMBM’s value drivers on value creation.FindingsBuilding on the business model canvas and the characteristics of internet health care, five value drivers of IMBM are identified, namely, functional value proposition, emotional value proposition, user involvement, resource capabilities and connection properties. And the five value drivers form three configurations, which are, respectively, labeled as resource-driven configuration, user-operated configuration and product-combined configuration. From the perspective of the integration of traditional and emerging theories, such as resource-based view, internet economics and value cocreation, each configuration leads to value creation and improves value results with different mechanisms behind it.Originality/valueFirst, combined with the business model canvas and the characteristics of internet health care, this paper identifies five value drivers of IMBM, thus improving the relevant research on internet health care. Second, based on the configurational effects, this paper discusses the mechanism behind the configurational effects of IMBM’s value drivers on value creation, thus expanding relevant research on the value creation of business models. Third, applying fsQCA and combining the advantages of qualitative research and quantitative research, this paper adds to the configurations of IMBM’s value drivers that achieve high-value results.
Universities and innovation – the case of hybrid courses
Authors: Pandey Satyendra C. , Panda Swati 
Published: May 2023

Purpose
Hybrid learning, integrating online methods of instruction with face-to-face learning methods, has recently gained increased attention. The literature on pedagogy and course management has focused on hybrid learning as a combination of virtual and physical environments, which can shift learning to a more student-centered model from the teacher-centered model. A gap exists in the literature related to the execution of hybrid learning and challenges faced by internal stakeholders, and the outcomes are achieved. This study aims to examine the implementation of hybrid learning courses and investigate the challenges and outcomes.

Design/methodology/approach
This study adopted a qualitative approach. This study presents a case of a management university in India. Ten semistructured interviews were conducted with the university officials, including the vice-chancellor, dean and faculty members. The data collection method also included reviewing university documents and reports.

Findings
While formalized knowledge transfer through online courses can facilitate knowledge dissemination, it has its own downsides: it needs to be contextualized; it requires additional resources; it is not a one size fits all policy, as its conducive to some and alienates others; and students may not completely adopt it.

Originality/value
This investigation attempts to examine the shift to hybrid learning in the Indian context.

PurposeThe purpose of this research is to provide an introduction into Hoshin Kanri and how it has been used with other methodologies and frameworks. Additionally, factors that impact successful Hoshin Kanri implementation and future research opportunities are explored.Design/methodology/approachA systematic literature review was conducted to determine the methodologies and frameworks that have previously been explored and identify factors that lead to successful Hoshin Kanri implementation as it relates in the Western world.FindingsEven though Hoshin Kanri has been used to a limited extent for decades in the West, there is still relatively little published research on the topic. In the period reviewed most published research was performed in the UK or USA. In addition, most years had less than two publications (the exception being five in 2020).Research limitations/implicationsThis literature review was primarily focused on the manufacturing sector, publications from 1990–2021, and available in English.Practical implicationsCurrent practitioners may use the research in this review to improve their current Hoshin Kanri practices using the techniques mentioned as a means of continuous improvement or to build a new framework for their own needs.Originality/valueThis paper makes an important contribution to the study of Hoshin Kanri as it provides: (1) an updated literature review regarding the study and application of Hoshin Kanri, (2) a qualitative analysis of alternative methodologies and frameworks to traditional Hoshin Kanri and (3) success factors when considering implementation of Hoshin Kanri within an organization and researchers with potential ideas for future research.
Tree and shrub expansion at treeline drive contrasting responses in a subarctic passerine community
Authors: Mizel Jeremy D. , Schmidt Joshua H. , Roland Carl A. , Mcintyre Carol L. 
Published: May 2023

AbstractInferences about the mechanisms of distributional change are often made from simple assessments of variation in the geographical positions of populations. However, direct assessments of species' responses to local habitat change may be necessary for proper understanding of the drivers of distributional dynamics.Amplified climate warming is inducing cascading impacts in boreal‐tundra regions including the expansion of conifers and deciduous shrubs (shrubs). In Denali National Park (Denali), Alaska, passerine birds are exhibiting rapid upslope shifts in distribution but the relative roles of conifer and shrub (woody vegetation) expansion in driving these shifts are unknown. Without directly assessing passerine‐vegetation dynamics, the assumption has been that the observed upslope shifts are indicative of shrub‐adapted passerines tracking the upslope expansion of shrubs. Here, we jointly investigate the processes of conifer and shrub expansion and their relationship to changes in passerine abundance in Denali.We used a remotely sensed vegetation cover timeseries (1985–2020) to assess the topographic and edaphic correlates of conifer and shrub expansion. We then assessed the impacts of changes in shrub and conifer cover on the relative abundance of 12 passerine species (1995–2020).Shrub and conifer colonization rates were highest at intermediate elevations near treeline. However, forest‐ and shrub‐adapted passerines differed in terms of the location in which their response was concentrated relative to treeline. The population growth rates of forest‐adapted passerines exhibited stronger effects of woody vegetation expansion at sites that were initially above treeline (IAT). In contrast, the population growth rates of shrub‐adapted passerines exhibited the negative effects of conifer expansion together with the positive effects of shrub expansion at initially below treeline sites. However, they showed a weak response to woody vegetation expansion at sites that were IAT.Below treeline conifer infilling appears to be pushing the elevational distributions of shrub‐adapted passerines upslope rather than these species following the pull of modest shrub expansion above treeline, as previously assumed.Overall, our findings illustrate the need for explicitly accommodating heterogeneity in habitat change at small spatial scales to properly view the distributional response, particularly when habitat change is concentrated at ecotones.
Trait‐mediated community assembly during experimental grassland restoration is altered by planting year rainfall

Published: May 2023

Abstract

Ecological restoration outcomes are highly variable, undermining efforts to recover biodiversity and ecosystem functions. One poorly understood source of variability is ‘year effects’—interannual variation in environmental conditions during the first year of restoration that alter successional trajectories of plant communities.

There have been few experimental tests disentangling planting years from other differences among restoration projects (e.g. edaphic conditions, restoration approach), particularly those resolving mechanisms for year effects such as planting‐year rainfall. Moreover, past year effect studies focused almost exclusively on species‐level consequences. Therefore, the extent to which year effects influence the traits of communities is unknown.

To address these gaps and provide a mechanistic test of how precipitation contributes to year effects, we conducted an experiment where we manipulated rainfall (drought, average and high levels) during the first growing season, replicated across three establishment year treatments to disentangle the effects of precipitation from other drivers of year effects. In each establishment year, we seeded the same species mix to initiate grassland restoration. We then surveyed plant community compositions annually for 5 years to quantify trait responses of restored communities to planting year rainfall.

We found that variation in planting‐year precipitation altered community assembly trajectories by influencing community‐weighted mean (CWM) trait composition, and these effects persisted for at least 5 years. Over time, CWM specific leaf area and CWM seed mass decreased and CWM plant height increased. The effect of age on CWM plant height was stronger in plots that received mean and high watering treatments compared to drought treatments. This effect was also observed for CWM seed mass, albeit weaker.

We also found some evidence for planting year effects unrelated to planting‐year rainfall for the three CWM traits, illustrating how interannually varying environmental conditions besides rainfall can generate persistent year effect on plant communities through their traits.

Synthesis and applications. Our results provide evidence for planting year rainfall interacting with community assembly to alter the functional trait composition of restored grasslands. This suggests that interannual variation in rainfall during establishment is an important source of divergent biodiversity and functional outcomes in restored grasslands.

AbstractMythimna separata and Mythimna loreyi are global pests of gramineous cereals, heavily controlled with synthetic insecticides. Here, we generated two high‐quality chromosome‐level genome assemblies for M. separata (688 Mb) and M. loreyi (683 Mb). Our analysis identified Z and W chromosomes, with few genes and abundant transposable elements (TEs) found on the W chromosome. We also observed a recent explosion of long interspersed nuclear elements (LINEs), which contributed to the larger genomes of Mythimna. The two armyworms diverged ~10.5 MYA, with only three chromosomes have intrachromosomal rearrangements. Additionally, we observed a tandem repeat expansion of α‐amylase genes in Mythimna, which may promote the digestion of carbohydrates and exacerbate their damage to crops. Furthermore, we inferred the sex pheromone biosynthesis pathway for M. separata, M. loreyi and Spodoptera frugiperda. We discovered that M. loreyi and S. frugiperda synthesized the same major constituents of sex pheromones through different pathways. Specifically, the double bonds in the dominant sex pheromone components of S. frugiperda were generated by Δ9‐ and Δ11‐desaturase, while they were generated by Δ11‐desaturase and chain‐shortening reactions in M. loreyi. We also identified pheromone receptor (PR) genes and inferred their corresponding components. These findings provide a better understanding of sex pheromone communication and promote the development of a new pest control strategy involving pheromone traps, which are more effective and environmentally friendly than current strategies.
A new metabolic trait in an acetogen: Mixed acid fermentation of fructose in a methylene‐tetrahydrofolate reductase mutant of Acetobacterium woodii
Authors: Moon Jimyung , Schubert Anja , Poehlein Anja , Daniel Rolf , Müller Volker 
Published: May 2023

AbstractTo inactivate the Wood–Ljungdahl pathway in the acetogenic model bacterium Acetobacterium woodii, the genes metVF encoding two of the subunits of the methylene‐tetrahydrofolate reductase were deleted. As expected, the mutant did not grow on C1 compounds and also not on lactate, ethanol or butanediol. In contrast to a mutant in which the first enzyme of the pathway (hydrogen‐dependent CO2 reductase) had been genetically deleted, cells were able to grow on fructose, albeit with lower rates and yields than the wild‐type. Growth was restored by addition of an external electron sink, glycine betaine + CO2 or caffeate. Resting cells pre‐grown on fructose plus an external electron acceptor fermented fructose to two acetate and four hydrogen, that is, performed hydrogenogenesis. Cells pre‐grown under fermentative conditions on fructose alone redirected carbon and electrons to form lactate, formate, ethanol as well as hydrogen. Apparently, growth on fructose alone induced enzymes for mixed acid fermentation (MAF). Transcriptome analyses revealed enzymes potentially involved in MAF and a quantitative model for MAF from fructose in A. woodii is presented.
