Published: December 2022

PurposeIn the absence of previous work, this study investigates how the psychological contract (PC) influences the safety performance of construction workers in China.Design/methodology/approachThe literature is first consulted to obtain a set of PC and safety performance measures that fits the specific situation of construction workers, which is then moderated by five construction experts. A questionnaire survey of 206 workers from 4 different construction sites is followed by a descriptive statistical analysis of the nature of the PC and level of the safety performance of the respondents. Finally, a regression analysis is used to ascertain the level of influence of the PS, and an analysis is made of the influence of PC on safety performance.FindingsA set of PC and safety performance measures is identified that fits in the construction workers' specific situation. The PC of the respondents is found to be intact and well-performed, and their safety performance is maintained at a high level. Safety performance is highly influenced by the state of the PC, with the three dimensions of safety performance (safety result, safety compliance and safety participation) positively correlated with the three dimensions of the PC (normative, interpersonal and developmental).Originality/valueSuggestions are made to improve safety production management and safety performance by providing adequate material and economic conditions, helping the workers establish good interpersonal relationships and realize their personal values.
Factors affecting performance of graduate architects in contract implementation management: a case study on housing projects in Malaysia
Authors: Tiew Si Yee 
Published: December 2022

PurposeGraduate architect plays an important role in contract implementation management when handling building construction projects. Graduate architects had been authorized to manage the projects in construction industry due to limited architects in the country. The capability of graduate architect when manage project is critical in reducing performance barriers encountered. The aim of this paper is to identify critical factors that affect graduate architect's performance during project implementation.Design/methodology/approachAn explorative study was undertaken to provide an insight into actual experiences of graduate architects in contract implementation management. The data were collected through face-to-face semi-structured interviews providing case studies on contract implementation management on housing projects in Malaysia and observation of the actual on-going projects.FindingsThe five most crucial factors affected graduate architects' performance related to lack of training in project documentation, failed to obtain professional and peer support in quality and assessment, isolate in role during project coordination, lack of education support in design process and unaware of legal aspects which delayed response to contractor.Research limitations/implicationsThis research focuses only on seven housing projects and semi-structured interviews with twenty graduate architects who in charge of those projects. As such, the resulting factors that affect graduate architect's performance are limited and are constrained only to the construction industry in Malaysia.Practical implicationsThis research examined the factors affecting graduate architect's performance which is a timely study, as the increasing number of population and developments will provide ample opportunities for them to perform.Originality/valueThe outcome of the study is expected to facilitate graduate architects to devise proactive risk mitigation measures to reduce impact of these factors and improve project delivery.
Do salespeople’s online profile pictures predict the number of online reviews? Effect of a babyface
Authors: Yim Alexis , Price Bradley , Agnihotri Raj , Cui Annie Peng 
Published: December 2022

Purpose
This study aims to investigate the impact of a salesperson’s babyface in his/her profile picture on the number of online reviews the salesperson receives. In addition to testing the direct relationship, this study explores the moderating roles of salesperson gender and consumer involvement.

Design/methodology/approach
Responding to the call for field-based consumer research, the authors test their theory using an experimental design and a field study. Study 1 employs an experimental design in high and low involvement service settings to test the effect of a babyface on consumers’ intention to write online reviews. Study 2 uses field data, utilising real estate salespeople’s online profile pictures to test the effect of salespeople’s babyface on the number of online reviews they receive. It does so by using an artificial intelligence facial recognition application interface.

Findings
A salesperson’s babyface results in fewer online reviews in situations in which consumers are highly involved in the purchase process. By contrast, a salesperson’s babyface engenders more online reviews when consumers purchase low involvement services. The adverse effect of a babyface on the number of online reviews, however, attenuates when a salesperson is female.

Research limitations/implications
Limited information about salespeople, a skewed number of online reviews and blurry online profile pictures from a real-world data set constitute the study’s limitations.

Practical implications
When consumers are highly involved in the purchase process, salespeople should appear mature in their online profile photos to engender more online reviews. However, salespeople providing low involvement services should opt for online profile pictures reflecting babyish facial features to generate more online reviews.

Originality/value
Research has shown that salespeople’s physical appearance plays an important role in consumers’ perceptions of salespeople and their performance. Although abundant research and practice have shown the importance of online reviews, less is known about how online profile pictures affect online reviews. Thus, building on well-studied cases of an overgeneralization effect, this work examines the extent to which salespeople’s babyface features in their online profile picture affects the number of online reviews received in a real-world setting.

Published: December 2022

PurposeConstruction 4.0 technology is a novel innovative technology that has been proved to enhance project performance. However, information on the concept's awareness, adoption readiness and challenges in developing economies is still scanty. The purpose of the study is to appraise awareness, adoption readiness and challenges of Construction 4.0 technologies in Nigeria to bring to the fore the state of art of these innovative technologies in the study area.Design/methodology/approachThe study used a convenient sampling technique to select 129 construction professionals (architects, engineers and quantity surveyors) in Osun State, Nigeria, who provided data for the study through a closed-ended structure questionnaire survey. The quantitative data supplied were analysed using frequency, percentile, Cronbach's alpha, mean score (MS) analysis and analysis of variance (ANOVA).FindingsThe overall awareness level of construction professionals in the study area about Construction 4.0 technologies is at a moderate level (MS = 3.03). The analysis of each component of the Construction 4.0 technologies shows that BIM (MS = 3.69) has the highest level of awareness, while augmented reality (MS = 2.51) has the least awareness level. More results show a significant difference in the opinion of the respondents, a significant difference in the respondents on 36% of the components of Construction 4.0 technologies. The adoption readiness of the Nigerian construction industry (NCI) to Construction 4.0 technologies is at an initial level (MS = 2.86). However, the 3D printing (MS = 3.36) and augmented reality (MS = 2.49) have the highest and lowest adoption readiness ratings, respectively. There is no significant difference in how respondents ranked the NCI adoption readiness on 73% of the components of Construction 4.0 technologies. The main challenges of Construction 4.0 technologies in the study area are lack of standardisation (MS = 4.02), lack of investment in research and development and cost of implementation (MS = 3.87) each. The result shows that there is perfect unanimity in the way respondents ranked the challenges of Construction 4.0.Practical implicationsThe study provided information on the status quo of Construction 4.0 technologies in the NCI to enhance improvement in practice and the attendant project delivery.Originality/valueThe study attempted to bring to the fore the state of the art on awareness, adoption readiness and challenges of Construction 4.0 technologies in Nigeria. The study's information will be valuable to improve project delivery.
A longitudinal study on knowledge organization publications: using hierarchical clustering and multidimensional scaling
Authors: Danesh Farshid , Ghavidel Somayeh 
Published: December 2022

Purpose
The purpose of this study was a longitudinal study on knowledge organization (KO) realm structure and cluster concepts and emerging KO events based on co-occurrence analysis.

Design/methodology/approach
This longitudinal study uses the co-occurrence analysis. This research population includes keywords of articles indexed in the Web of Science Core Collection 1975–1999 and 2000–2018. Hierarchical clustering, multidimensional scaling and co-occurrence analysis were used to conduct the present research. SPSS, UCINET, VOSviewer and NetDraw were used to analyze and visualize data.

Findings
The “Information Technology” in 1975–1999 and the “Information Literacy” in 2000–2018, with the highest frequency, were identified as the most widely used keywords of KO in the world. In the first period, the cluster “Knowledge Management” had the highest centrality, the cluster “Strategic Planning” had the highest density in 2000–2018 and the cluster “Information Retrieval” had the highest centrality and density. The two-dimensional map of KO’s thematic and clustering of KO topics by cluster analysis method indicates that in the periods examined in this study, thematic clusters had much overlap in terms of concept and content.

Originality/value
The present article uses a longitudinal study to examine the KO’s publications in the past half-century. This paper also uses hierarchical clustering and multidimensional scaling methods. Studying the concepts and thematic trends in KO can impact organizing information as the core of libraries, museums and archives. Also, it can scheme information organizing and promote knowledge management. Because the results obtained from this article can help KO policymakers determine and design the roadmap, research planning, and micro and macro budgeting processes.
Institutional change through departmental quality assurance self-studies
Authors: Kolomitro Klodiana , Inglese Jenna , Stockley Denise , Scott Jill , Wright Madison 
Published: December 2022

Purpose
In 2010, the Ontario Universities Quality Assurance Council was established and became responsible for monitoring the quality of university programs, and each university was tasked with establishing institutional quality assurance purposes. The purpose of this study is to evaluate the effectiveness of the quality assurance process at facilitating change at one Canadian institution.

Design/methodology/approach
To better understand the impacts of quality assurance, the authors analyzed 39 self-study documents, which were completed for all academic programs at Queen’s University. Focus groups were also conducted with key stakeholders to gain more insights into the institutional change that resulted from completing these self-studies.

Findings
After the analysis of the self-studies and focus groups, three themes emerged as impacts of completing self-studies: teaching and learning, identity and collaboration and resource allocation and strategic planning. This study demonstrates that self-studies completed by departments have value beyond simply meeting the provincial mandate, as they are effective in catalyzing positive institutional change.

Research limitations/implications
The self-study documents were created for the purpose of institutional quality assurance process, not this research study, therefore limiting the data that could be collected.

Practical implications
Four considerations are provided at the end of this study to spark conversations at other institutions when reviewing and assessing the impact of their quality assurance processes.

Originality/value
To the best of the authors’ knowledge, this is the first time self-studies have been analyzed to evaluate the quality assurance process.
Bright and dark side of knowledge management practices in firms using information systems: examining different moderating impacts
Authors: Chatterjee Sheshadri , Chaudhuri Ranjan , Vrontis Demetris 
Published: December 2022

Purpose
This research aims to find out the impact of knowledge sharing (KS) and knowledge hiding (KH) on employee creativity (EC) and eventually on firm innovativeness (FI). The study also investigates the moderating roles of incentive focus, preventive focus and enterprise social networking (ESN) adoption on EC and FI.

Design/methodology/approach
The study used an empirical research approach and created a research model using resource-based view theory and literature. The model was validated using the partial least squares structural equation modeling technique to analyze data from 347 respondents from Indian firms.

Findings
The authors found that there is a considerable moderating impact of all three moderators on EC and firms’ innovativeness. KS has a positive impact and KH has a negative impact on EC.

Research limitations/implications
Knowledge can be shared within a firm by using an ESN tool. KS is the brighter side of the knowledge management process, whereas KH is the darker side of it. The study presents insights into and prescriptions for the bright and dark sides of knowledge management. The study results also imply that the firm managers must try to properly integrate the knowledge acquired from various stakeholders such as institutions, customers, competitors and suppliers as well as to focus on the tacit, precious and distinctive knowledge helpful to sustain long-term relationships with the valued external sources. The study empirically validates the model with the respondents from Indian firms, and thus the proposed model cannot be generalized.

Originality/value
Few research studies have examined both the bright and dark sides of the knowledge management process. There is a growing interest among researchers and practitioners to explore these sides of the knowledge management process using information systems and knowledge risk. Moreover, the proposed theoretical model has a high explanative power that makes the model effective and unique.
Mycorrhizal fungi alter root exudation to cultivate a beneficial microbiome for plant growth
Authors: Xu Yunjian , Chen Zhe , Li Xiaoyu , Tan Jing , Liu Fang , Wu Jianping 
Published: December 2022

Abstract

Arbuscular mycorrhizal (AM) fungi traditionally form symbioses with most plant species. Although AM fungi have critical effects on microbial communities, the pathways showing how AM fungi shape rhizosphere bacterial communities and their functions are rarely explored.

Here, through three systematic experiments, AM fungi–bacteria interactions were first investigated in the rhizosphere of Lotus japonicus, then the interactions were confirmed by a second experiment with wild‐type and a mycorrhiza‐defective mutant ljcbx of L. japonicus. The mechanisms were presented by adding core bacteria and AM fungi to the plant rhizosphere in the third experiment.

We found that AM fungi–bacteria interactions enhanced host plant growth and identified a core bacterial group that uniquely enhanced host plant growth. Adding core bacteria and AM fungi promoted host growth and nutrient acquisition compared to adding AM fungi or core bacteria independently.

Allelopathic substances secreted by AM fungal colonizing host roots to recruit the rhizosphere bacteria were detected by the multi‐omics joint analysis, showing that arachidonic acid was the main allelopathic substance that affected AM fungi–bacteria interactions.

Our findings provide direct evidence that mycorrhizal infection simulated root exudation, such as arachidonic acid, recruited a beneficial microbiome to the host rhizosphere, increasing plant growth and soil nutrient turnover.

Authors: Sandgren Olof , Andersson Ketty , Lyberg Åhlander Viveka , Rosqvist Ida , Hansson Kristina , Sahlén Birgitta 
Published: December 2022

AbstractBackgroundContinued professional development (CPD) is required for updated skills and knowledge. This study evaluates the efficacy of a CPD programme for mainstream school teachers.AimsIn an 11‐week intervention programme, speech–language therapists (SLTs) presented the participating teachers with whole‐class teaching techniques aimed at creating a language and communication‐supporting classroom environment. The effects of the intervention on the language development of the students in the teachers’ classes were assessed.Methods & ProceduresA total of 211 first‐ and second‐year students (Mage = 7;6, range = 6;5–8;9) underwent standardized language assessments of receptive and expressive language abilities before and after their teachers’ participation in the CPD. The students were divided into intervention and delayed intervention groups to enable randomized intervention allocation. Linear mixed modelling was used to estimate the individual and interaction effects of group, time and demographic factors.Outcomes & ResultsSignificant effects of time, group and school, respectively, but no interaction between time and group indicates that while all students advanced between assessments, the progress was not attributable to the teachers’ participation in the CPD.Conclusions & ImplicationsResults are discussed in light of those of recent studies of universal services to support optimal language development.WHAT THIS PAPER ADDSWhat is already known on this subjectAlthough inconclusive, previous research indicates that intervention delivered to teachers by SLTs has the potential to improve the language abilities of the students in the teachers’ classrooms.What this paper adds to existing knowledgeThis study explored the language development of first‐ and second‐year mainstream school students whose teachers took part in a CPD programme aimed at establishing language and communication‐supporting teaching techniques. Results indicate that the development of the students’ language abilities could not be attributed to the teachers’ participation in the CPD.What are the potential or actual implications of the work?SLTs are often asked to guide teachers and teaching staff rather than themselves conduct individual assessments and interventions. The results of this trial can be used to inform the discussion on how to prioritize between tasks.
Opportunities and challenges in discussing racism during primary care visits

Published: December 2022

AbstractObjectiveTo understand how patients and primary care practitioners (PCPs) discuss racism and their perspectives on having these conversations during primary care visits.Data Sources/Study SettingWe conducted semi‐structured interviews from September 2020–March 2021 at a Federally Qualified Health Center in the San Francisco Bay Area.Study DesignWe conducted an inductive qualitative descriptive pilot study using one‐on‐one, semi‐structured interviews with 5 members of a Patient Advisory Council and 10 internal medicine PCPs.Data Collection/Extraction MethodsInterviews were conducted via video conferencing, recorded, and transcribed. An iterative analytic process was used to thematically assess participants' experiences and perspectives and identify key themes.Principal FindingsPatients and PCPs identified benefits from engaging in conversations about racism during primary care visits and noted challenges and concerns. Patients and PCPs highlighted strategies to advance communication about racism in primary care.ConclusionsInitiating conversations about racism with patients in primary care can be meaningful, but also has risks. More research is needed for deeper exploration of patients' perspectives and development of trainings. Improving how PCPs communicate with patients about racism represents an opportunity to advance antiracism in medicine and improve health outcomes for individuals who have historically been poorly served by our health care system.
Safety assessment of herbal supplement components targeting hepatotoxicity and CYP3A4 induction in cell‐based assay using HepG2 cells
Authors: Kondo Takashi , Suzuki Ippei , Chiba Tsuyoshi , Tousen Yuko 
Published: December 2022

AbstractHerbal supplements can cause hepatotoxicity and drug interactions via hepatic cytochrome P‐450 (CYP) in some cases. However, there is no simple and stable cell‐based assay to conduct a screening for hepatotoxicity and CYP induction. In the present study, we selected 14 components of the herbal supplement based on our previous reports and investigated the safety of the herbal supplement components focusing on toxicity and CYP3A4 induction in a cell‐based assay using HepG2. The toxicity of the components was examined by lactate dehydrogenase (LDH) and cell proliferation assays. Then, the CYP3A4 induction of the components were examined by a reporter assay using reporter vectors of CYP3A4. The vector includes the CYP3A4 proximal promoter (CYP3A4PP) and the xenobiotic‐responsive enhancer module (XREM) regions. Luteolin (LU) significantly increased LDH activity and decreased cell proliferation activity that suggests LU may cause toxicity in HepG2 cells. Quercetin (QU) increased the transcriptional activity of CYP3A4 (1.5‐fold of control) in the reporter assay. However, the induction of QU was slightly in comparison to the validation of the transcriptional activity of CYP3A4 treated with CYP3A4 inducers. The CYP3A4 induction of QU may not involve CYP3A4PP but involves the XREM response. Throughout our results, the method in the present study may be useful for a safety assessment of herbal supplements, primarily focusing on hepatotoxicity and CYP3A4 induction.Practical ApplicationEven though there are problems with herbal supplements, studies related to toxicity are not actively carried out. The present methods may apply to the safety assessment for herbal supplements and be useful for the prevention and verification of health hazards caused by herbal supplements (the summary is shown in Figure S2).
