Published: September 2022

ABSTRACTStreptococcus gallolyticussubsp.gallolyticus (SGG)is an opportunistic bacterial pathogen strongly associated with colorectal cancer. Here, through comparative genomics analysis, we demonstrated that the genetic locus encoding the Type VIIb Secretion System (T7SSb) machinery is uniquely present inSGGin two different arrangements.SGGUCN34 carrying the most prevalent T7SSb genetic arrangement was chosen as the reference strain. To identify the effectors secreted by this secretion system, we inactivated the essC gene encoding the motor of this machinery. Comparison of the proteins secreted by UCN34 WT and its isogenic ΔessC mutant revealed six T7SSb effector proteins, including the expected WXG effector EsxA and three LXG-containing proteins. In this work, we characterized an LXG-family toxin named herein TelE displaying pore-forming activity. Seven homologs of TelE harboring a conserved glycine zipper motif at the C-terminus were identified in differentSGGisolates. Scanning mutagenesis of this motif showed that the glycine residue at position 470 was crucial for TelE pore-forming activity. Unlike other pore-forming toxins commonly antagonized by a membrane protein, TelE activity was antagonized by a small protein TipE belonging to the DUF5085 family. Overall, we report herein a uniqueSGGT7SSb effector exhibiting a pore-forming activity against non-immune bacteria.IMPORTANCEIn this study, 38 clinical isolates ofStreptococcus gallolyticussubsp. gallolyticus(SGG) were sequenced and a genetic locus encoding the Type VIIb secretion system (T7SSb) was found conserved and absent from 16 genomes of the closely relatedS. gallolyticussubsp.pasteurianus (SGP). The T7SSb is abona fidepathogenicity island. Here, we report that the model organismSGGstrain UCN34 secretes six T7SSb effectors. One of the six effectors named TelE displayed a strong toxicity when overexpressed inEscherichia coli. Our results indicate that TelE is a pore forming toxin whose activity can be antagonized by a non-canonical immunity protein named TipE. Overall, we report a unique toxin-immunity protein pair and our data expand the range of effectors secreted through T7SSb.
Exploring institutional pressure, the top management team's response, green innovation adoption, and firm performance: evidence from Taiwan's electrical and electronics industry
Authors: Huang Yi-Chun , Huang Chih-Hsuan 
Published: September 2022

PurposePrior research on green innovation has shown that institutional pressure stimulates enterprises to adopt green innovation. However, an institutional perspective does not explain why firms that face the same amount of institutional pressure execute different environmental practices and innovations. To address this research gap, the authors linked institutional theory with upper echelons theory and organization performance to build a comprehensive research model.Design/methodology/approachA total of 800 questionnaires were issued. The final usable questionnaires were 195, yielding a response rate of 24.38%. AMOS 23.0 was used to analyze the data and examine the relationships between the constructs in our model.FindingsInstitutional pressures affected both green innovation adoption (GIA) and the top management team's (TMT's) response. TMT's response influenced GIA. GIA was an important factor affecting firm performance. Furthermore, TMT's response mediated the relationship between institutional pressure and GIA. Institutional pressures indirectly affected green innovation performance but did not influence economic performance through GIA. Finally, TMT's response indirectly impacted firm performance through GIA.Originality/valueThe authors draw on institutional theory, upper echelons theory, and a performance-oriented perspective to explore the antecedents and consequences of GIA. This study has interesting implications for leaders and managers looking to implement green innovation and leverage it for firm performance to out compete with market rivals as well as to make the changes in collaboration with many other companies including market rivals to gain success in green innovation.
Built environment academics for 21st-century world of teaching: stakeholders' perspective
Authors: Ebekozien Andrew , Aigbavboa Clinton , Aliu John 
Published: September 2022

PurposeResearch reveals that the built environment graduates are not matching the needs of the 21st century construction industry. Evidence shows that the built environment academics (BEA) struggle to reskill and upskill to meet the industry's demand. Studies about Nigeria's BEA's perceived barriers in meeting the 21st-century industry demands are scarce. Thus, the paper investigated the perceived barriers and measures to improve BEA in Nigeria's 21st-century world of teaching. The outcome intends to enhance teaching practices and increase employability in the built environment disciplines.Design/methodology/approachData were sourced from elite virtual interviews across Nigeria. The participants were well informed about Nigeria's built environment education and the possible barriers hindering 21st-century teaching from improving employable graduates in the built environment professionals (BEP). The researchers adopted a thematic analysis for the collected data and supplemented the data with secondary sources.FindingsThe study shows that BEA needs to improve BEA's teaching mechanism. Improving BEA will enable the built environment graduates to meet the minimum standards expected by the 21st-century industry. Findings categorised the perceived 22 barriers facing BEA into internal stakeholders-related barriers, external stakeholders-related barriers, and common barriers. Also, findings proffered practicable measures to improve BEA in the workplace via improved industry collaboration and technological advancement.Research limitations/implicationsThe research is restricted to the perceived barriers and measures to improve BEA in 21st-century teaching in Nigeria via a qualitative research design. Future research should validate the results and test the paper's proposed framework.Practical implicationsThe paper confirms that the BEA requires stakeholder collaboration and technological advancement measures to improve teaching in the 21st century, leading to enhanced employability graduates. The paper would stir major stakeholders, especially BEA, and advance the quality of employable graduates in the Nigerian built environment professions.Originality/valueThe thematic network and proposed framework could be employed to stimulate Nigeria's BEA for better service delivery. This intends to create an enabling environment that will enhance stakeholders' collaboration and technological advancement for the BEA to produce better employable graduates in the 21st century.
Does firms and managerial experience matter for exporting? The case of selected EU member and non-member countries
Authors: Cieślik Andrzej , Michałek Jan Jakub , Michałek Anna 
Published: September 2022

PurposeThe main goal of this paper is to study empirically the importance of experience of top managers and firms for export performance, having controlled for a number of firm characteristics.Design/methodology/approachThe study is based on the probit model applied to the 2020 edition of the BEEPS firm level survey. The authors analyze firms in 15 EU member and 15 non-member countries.FindingsThe results indicate that firm experience can increase the probability of direct exporting, but is not significant for indirect exporting. The results also support the importance of interaction between experience of managers and experience of firms. The authors conclude that only the combination of managerial and firm experience can have a positive and significant effect for direct exporting. This relationship is more pronounced in the case of EU members.Research limitations/implicationsThe main limitations of our approach are related to data constraints. These include availability of only cross-sectional data and the limited number of individual characteristics of managers.Practical implicationsThe importance of experience for exporting suggests that firms can break into foreign markets by hiring more experienced managers.Social implicationsPost-communist countries can improve their export performance by hiring more experienced managers that would stimulate direct exports. Moreover, they can also export indirectly through intermediaries.Originality/valueIn contrast to previous studies, the authors used a model proposed by Jørgensen and Schroder (2008) in which the authors endogenized the costs of exporting by linking them to firm and managerial experience. Then, the authors validated empirically the importance of experience for firm export performance, having controlled for the set of individual firm characteristics.
Are single-item needs' and values' measures a good alternative to multi-item measures for sport marketers?

Published: September 2022

PurposeThis paper aims to determine if single-item (SI) needs' and values' measures have similar reliability and validity values to multi-item (MI) measures of the same constructs and thus could be substituted by sport marketers to predict internal motivating aspects of sport consumer attitudes and behavior. In addition, the authors wish to determine whether a small subset of needs and values listed in current measures are sufficient to predict sport consumer attitudes and behavior.Design/methodology/approachIn this two-study design, the first study was a national sample (N = 439) comparing reliability and validity of single-item scales to multi-item scales. In the second study the authors collected data from fans and spectators of four different teams (N1 = 583; N2 = 1164; N3 = 213; N4 = 404) to determine the impact of needs and values on sport consumer attitudes and behavior.FindingsThe authors determined that in 89% of the scales, single-item measures of needs and values were just as reliable and valid as their associated multi-item measures. The authors also found that a small subset of the needs and values explain a meaningful amount of variance in sport consumer attitudes and behaviors.Research limitations/implicationsThe authors determined that in 89% of the scales, single-item measures of needs and values were just as reliable and valid as their associated multi-item measures. The authors also found that a small subset of the needs and values explain a meaningful amount of variance in sport consumer attitudes and behaviors.Originality/valueThe authors show that as motives for sport consumption, single-item measures of personal needs and values are equivalent to multi-item measures and not all needs and values used in previous sport research are necessary because they do not predict a meaningful amount of variance in sport consumer attitudes and behaviors. The authors identified a small number of single-item measures that practitioners can easily use in short surveys that will predict a statistically meaningful amount of variance in sport consumer attitudes and behaviors.
Shocks and IS user behavior: a taxonomy and future research directions
Authors: Meier Marco , Maier Christian , Thatcher Jason Bennett , Weitzel Tim 
Published: September 2022

PurposeJarring events, be they global crises such as COVID-19 or technological events such as the Cambridge Analytica data incident, have bullwhip effects on billions of people's daily lives. Such “shocks” vary in their characteristics. While some shocks cause, for example, widespread adoption of information systems (IS) as diverse as Netflix and Teams, others lead users to stop using IS, such as Facebook. To offer insights into the multifaceted ways shocks influence user behavior, this study aims to assess the status quo of shock-related literature in the IS discipline and develop a taxonomy that paves the path for future IS research on shocks.Design/methodology/approachThis study conducted a literature review (N = 70) to assess the status quo of shock-related research in the IS discipline. Through a qualitative study based on users who experienced shocks (N = 39), it confirmed the findings of previous literature in an illustrative IS research context. Integrating the findings of the literature review and qualitative study, this study informs a taxonomy of shocks impacting IS use.FindingsThis study identifies different ways that shocks influence user behavior. The taxonomy reveals that IS research could profit from considering environmental, private and work shocks and shedding light on positive shocks. IS research could also benefit from examining the urgency of shocks, as there are indications that this influences how and when individuals react to a specific shock.Originality/valueFindings complement previous rational explanations for user behavior by showing technology use can be influenced by shocks. This study offers a foundation for forward-looking research that connects jarring events to patterns of technology use.
Overview international best practices on customer due diligence and related anti-money laundering measures
Authors: Chitimira Howard , Munedzi Sharon 
Published: September 2022

Purpose
The anti-money laundering (AML) frameworks of many countries were generally influenced by the international best practices of money laundering that were first established in 1988 through the Basel Committee on Banking Supervision (BCBS). The general belief is that these international best practices are applicable in all jurisdictions, although most countries are still affected by money laundering. The international best practices are universal measures that were developed as a yardstick to control and curb money laundering globally. Nonetheless, international best practices for money laundering are not tailor-made for specific jurisdictions and/or countries. Therefore, it remains the duty of respective jurisdictions and/or countries to develop their own context-sensitive AML measures in accordance with international best practices. An overview of the AML international best practices that were developed and adopted by several countries are analysed in this paper. These include customer due diligence measures established by the BCBS, the financial action task force (FATF) standards, as well as the ongoing monitoring and the risk-sensitive approach that were implemented to curb money laundering globally.

Design/methodology/approach
The article analyses the AML international best practices that were developed and adopted by several countries. These include customer due diligence measures established by the BCBS, the FATF standards, as well as the ongoing monitoring and the risk-sensitive approach that were implemented to curb money laundering globally.

Findings
It is hoped that policymakers and other relevant persons will use the recommendations provided in the paper to enhance the curbing of money laundering in financial institutions globally.

Research limitations/implications
The paper does not provide empirical research.

Practical implications
The study is useful to all policymakers, lawyers, law students and regulatory bodies globally.

Social implications
The study seeks to curb money laundering in the economy and society globally.

Originality/value
The study is original research on the use of AML/counter financing of terrorism international best practices to curb money laundering activities globally.
Whither monetary values of public cultural, heritage and scientific collections for financial reporting purposes
Authors: Carnegie Garry D. , Kudo Eiichiro 
Published: September 2022

PurposeUsing the most available literature, this viewpoint takes and supports the argument that public cultural, heritage and scientific collections of not-for-profit cultural heritage or arts institutions are non-financial resources, expressly in the specific organisational and social contexts in which they are held, for preservation, conversation and protection into perpetuity. These collections are, therefore, not “assets” or “heritage assets” for recognition in statement of financial position.Design/methodology/approachTo clarify and augment the literature in developing better understanding of how the monetary valuation of public cultural, heritage and scientific collections for general purpose financial reporting purposes is both not fit-for-purpose in these contexts and at least potentially misleading to stakeholders.FindingsThe evaluation of this public sector financial reporting issue portrays to be fit-for-purpose in its social and organisational contexts in which public, non-profit collecting institutions operate. Accounting's role is not the change contexts in the public sector into settings which they are, in substance, not.Originality/valueTo contribute to the overcoming of controversy by illuminating to both accounting professionals and heritage professionals the vexed issues involved in its ongoing discussion and debate. It is argued that there is no need for any accounting standard to be issued on this topic, which would lead to financial values being placed on non-financial cultural, heritage and scientific collections resources in statements of financial position, thereby misrepresenting these collections.
Digital consumer engagement: examining the impact of native advertising exposure in a social network
Authors: Sussman Kristen L. , Bright Laura F. , Wilcox Gary B. 
Published: September 2022

PurposeThe digital environment afforded by social networks has created an opportunity to understand more clearly the impact of social media native advertising on advertising processing outcomes. Thus, the current study integrates native advertising with engagement literature to compare engagement outcomes between feed and banner placements before analyzing engagement outcomes of sponsored social media posts by advertising objective. This work aims to contribute to advertising effectiveness literature arguing for the importance of engagement as a measure of effectiveness.Design/methodology/approachFacebook advertising data were collected from a convenience sample of 10 Facebook advertisers that accounted for roughly $414,000 in advertising spend. Panel data, which are also called longitudinal or cross-sectional time-series data, used 26 months of data from the 10 advertisers to measure relationships between native advertising exposure and digital consumer engagement with advertising by advertising objectives of brand awareness, link clicks, conversions, post-engagement and video views.FindingsExposure to native advertising was a strong predictor of advertising processing and consumption using the three variables of interest: clicks, comments and shares. Ads reaching consumers while natively consuming content in their feed resulted in statistically significant improvements in impressions and clicks when compared to banner ads. Exposure to native ads was significantly related to all engagement outcomes of interest, except for advertisers who chose post-engagement as their advertising objective.Practical implicationsThe results suggest that for advertisers seeking clicks, post-engagement objectives should likely be avoided. For this group, impressions were not related to link clicks but were related to comments and shares. Native advertising placements in the feed, however, are generally more effective than banner ads on Facebook for advertisers seeking engagement.Research limitations/implicationsThis research is one of few studies to use longitudinal advertising data to explore engagement effects using real-world data collected from a diverse set of Facebook advertisers over a 26-month period. This study shows that interactive marketers using a social media feed to reach consumers can expect positive outcomes in advertising consumption, affective and cognitive processing and advocacy, but those outcomes may vary by advertising objective.Originality/valueGiven the uniqueness of the data set, the findings contribute to native advertising literature and to the literature on digital consumer engagement with advertising in social media. The study also provides empirical support for the efficacy of native advertising.

Published: September 2022

PurposeThis study aims to investigate the technology usage behaviour of the tourists in line with the modified unified theory of acceptance and use of technology (UTAUT) model.Design/methodology/approachData were collected from a survey of 265 tourists using the random sampling technique. Partial least squares-based structural equation modelling (PLS-SEM) technique was used to analyze the data.FindingsThe findings revealed that performance expectancy, hedonic motivation and habit significantly influence the behavioural intention of tourists to use information and communication technology (ICT), while effort expectancy, social influence, and facilitating conditions do not have a significant influence. However, actual ICT usage behaviour largely depends on the behavioural intention of the tourists, and their habits, while the facilitating conditions do not have any influence in this case.Practical implicationsThe findings uncover the core factors influencing tourists' actual ICT use behaviour that can assist the concerned stakeholders in designing tourism planning and sales. The study results also offer pathways for the world's tourism industry for a healthy recovery from the COVID-19 pandemic.Originality/valueThe findings have made robust contributions by extending the existing UTAUT-based literature by adding two new moderators in the relationship between behavioural intention and actual ICT usage behaviour.
