Transcriptional enhancers regulate gene expression in a developmental-stage and cell-specific manner. They were originally defined as individual regulatory elements that activate expression regardless of distance and orientation to their cognate genes. Genome-wide studies have shown that the mammalian enhancer landscape is much more complex, with different classes of individual enhancers and clusters of enhancer-like elements combining in additive, synergistic and redundant manners, possibly acting as single, integrated regulatory elements. These so-called super-enhancers are largely defined as clusters of enhancer-like elements which recruit particularly high levels of Mediator and often drive high levels of expression of key lineage-specific genes. Here, we analysed 78 erythroid-specific super-enhancers and showed that, as units, they preferentially interact in a directional manner, to drive expression of their cognate genes. Using the well characterised α-globin super-enhancer, we show that inverting this entire structure severely downregulates α-globin expression and activates flanking genes 5’ of the super-enhancer. Our detailed genetic dissection of the α-globin locus clearly attributes the cluster’s functional directionality to its sequence orientation, demonstrating that, unlike regular enhancers, super-enhancers act in an orientation-dependent manner. Together, these findings identify a novel emergent property of super-enhancers and revise current models by which enhancers are thought to contact and activate their cognate genes.
Levelling up or down: leader’s strategies to encounter downward envy in family-owned software houses
Authors: Aftab Shafaq , Saleem Irfan , Belwal Rakesh
Published: July 2022

Purpose

This study aims to invoke social comparison theory and researches mainly on leaders’ downward envy at workplaces in a collectivist culture. The study also aims to infer and explain the constructive and destructive behaviour of benign envy (BE) and malicious envy (ME) in the workplace by studying supervisor-subordinate dyads.

Design/methodology/approach

A survey was conducted to test the proposed hypotheses. The sample included 352 randomly chosen supervisor-subordinate dyads from registered software houses in Pakistan. Partial least square SEM was used to test the proposed model and hypotheses.

Findings

This research identified that the leaders' gratitude and workplace friendship encourage leaders to adopt a levelling-up strategy to encounter benign envy (BE). In contrast, subordinates’ low level of loyalty and affect towards supervisors cause ME. The study also found that BE motivates frustrated supervisors to behave positively, whereas ME triggers the envious supervisor to threaten their aides with abusive supervision. However, envious supervisors with high core self-evaluation and gratitude are more likely to reflect self-improvement.

Practical implications

This study gives key insights to organisations on recognising the potential of downward envy, using it purposefully, and managing the consequences constructively. For instance, organizations could train leaders to understand the holistic view of downward envy to help them focus on self-improvement instead of abusing employees. In addition, training employees on envy could help them demonstrate warmth and competence.

Originality/value

The study is original and valuable in three aspects. Theoretically, this study develops a generic framework for dealing with downward envy. Contextually, the study brings a piece of evidence from software houses in Asia to study downward envy. Practically, this study suggests tactics to deal with downward envy in family-owned tech firms operating in emerging markets.
The effects of organizational positioning and donation recognition on charitable giving: insights from moral foundations theory
Authors: Paramita Widya , Septianto Felix , Escadas Marco , Arnita Devi , Nasution Reza Ashari
Published: July 2022

Purpose

The present research aims to investigate the influence of organizational positioning by drawing upon moral foundations theory in relation to driving charitable giving, and the moderating role of recognition in this regard.

Design/methodology/approach

Two experimental studies were conducted to examine the interactive effect of organizational positioning emphasizing a binding (vs an individualizing) moral foundation and donation recognition on charitable giving. Study 1 was conducted in Indonesia, while Study 2 was conducted in the US.

Findings

This research demonstrates that individuals will give higher donations to an organization with a binding (vs an individualizing) moral foundation that provides donation recognition. Further, this effect is mediated by social identity signaling.

Originality/value

The findings of this research provide a novel perspective on how organizational positioning can influence whether donation recognition increases charitable giving. Moreover, the findings offer managerial implications to non-profit organizations developing effective charitable campaigns in terms of combining appropriate organizational positioning and donation recognition strategies.
Factors promoting customer citizenship behaviours and the moderating role of self-monitoring: a study of ride-hailing services
Authors: Van Tonder Estelle , Petzer Daniel J.
Published: July 2022

Purpose

This study aims to broaden understanding of why customers engage in helping and feedback citizenship behaviours. Beyond traditional attitude–behaviour relationships, limited insight is available on the additional role of symbolic factors, such as self-congruence perceptions, in motivating citizenship behaviours. Literature further suggests self-monitoring affects social behaviours, yet extant research has not accounted for this personality trait’s moderating influence on customer helping and feedback citizenship behaviours. Accordingly, a research model is developed, providing novel insight into factors promoting helping and feedback citizenship behaviours and the moderating role of self-monitoring in a ride-hailing service context.

Design/methodology/approach

The research is guided by self-monitoring literature and the social exchange and similarity-attraction theories. Survey data from 609 ride-hailing customers in an emerging market country is analysed using multi-group confirmatory factor analysis and structural equation modelling, and the chi-square difference test.

Findings

This study shows that perceived justice (a cognitive attitudinal factor) influences helping citizenship intention in the low self-monitoring group, while self-congruity (a symbolic factor) affects helping and feedback citizenship intention in the high self-monitoring group. Affective commitment towards the ride-hailing brand (an affective attitudinal factor) does not impact customer citizenship intentions.

Research limitations/implications

Although customers may be interested in brands’ functional and symbolic benefits, positive attitudes about the service experienced motivate low self-monitors, while a symbolic-driven factor like self-congruence is more successful in motivating high self-monitors to engage in customer citizenship behaviours.

Originality/value

Novel insight is obtained into the additional influence of self-congruity on customer citizenship behaviours, a neglected factor in extant research involving customer citizenship behaviours that is explained by the similarity-attraction theory. Furthermore, this study provides a pioneering view of the relevance of the self-monitoring theory in moderating customer citizenship behaviours, specifically in ride-hailing services.
Privacy matters: impact of ethical organization care and government regulations on customer patronage
Authors: Bano Sobia , Mirza Muhammad Zeeshan , Sohail Marva , Javaid Muhammad Umair
Published: July 2022

Purpose

The coronavirus disease 2019 (COVID-19) epidemic has given an upsurge to online retailing in Pakistan. This shift has escalated the issues about privacy concerns among consumers. Keeping in view the growing concerns, the objective of this study is to investigate customer patronage in online shopping and the role of privacy concerns in this relationship.

Design/methodology/approach

To generalize the relationship between antecedents and outcomes of privacy concerns, a cross-disciplinary macro model was used. Data were collected through a survey method from the consumers who used credit and debit cards during online shopping.

Findings

Results show that government regulations have a significant positive relationship with privacy concerns and customer patronage. Privacy concerns are found to have a significant negative relationship with organizational ethical care while customer patronage was found to have a significant positive relationship with organizational ethical care. Customer patronage was also found to have a significant negative relationship with privacy concerns. Privacy concerns mediated the relationship between government regulations and customer patronage, whereas privacy concerns does not mediate the relationship between organizational ethical care and customer patronage.

Originality/value

The research adds to the existing literature and highlights the customer behavior toward online shopping/e-commerce in developing economies. The research gives a direction to stakeholders to counter privacy concerns and ensure safer e-commerce practices.
Female executives and firm value: the moderating effect of co-CEO power gaps
Authors: Hong Jiyeun , Kim Su-In
Published: July 2022

Purpose

This study aims to examine the moderating effect of co-CEO power gaps on the impact of female executives on firm value. Several studies have suggested that female executives have a positive effect on improving firm value. The authors would like to examine whether this relationship changes because of co-CEO power gaps.

Design/methodology/approach

For empirical analysis, 426 non-financial companies are selected from companies listed in the Korean securities market from 2013 to 2018. The relationships between dummy variables of female CEOs, outside directors, registered executives and Tobin’s Q are examined, and the moderating effect of co-CEO power gaps that scored various factors is verified.

Findings

The results of this study show that female executives have a positive impact on firm value, but the larger the co-CEOs power gap is, the weaker that impact is.

Practical implications

The mutual monitoring of co-CEOs substitutes for governance mechanisms, but if there are power gaps between co-CEOs, then the leadership cannot be equitably shared and the mutual monitoring effect can be weakened.

Originality/value

This study contributes to research on corporate executives by analyzing the relationship between female executives related to shared leadership and firm values in Korean companies. Especially, this study finds that the role of female executives is differentiated according to co-CEO power gaps by using the CEO power index that reflects the characteristics of Korean corporate governance.
Natural convection in a sinusoidally heated cavity filled with ferrofluid in the presence of partial variable magnetic field
Authors: Geridonmez Pekmen , Oztop Hakan
Published: July 2022

Purpose

The purpose of this study is to investigate partial magnetic source (MS) effect on natural convection (NC) flow of a ferrofluid flow in a cavity with sinusoidally heated vertical walls. The combination of ferrohydrodynamics and magnetohydrodynamics due to the variable magnetic field (MF) and magnetite nanoparticles in one part of the cavity, and the classical NC in the other part of the cavity are concerned.

Design/methodology/approach

The dimensionless equations in stream function-vorticity form are numerically solved by radial basis functions (RBF) based collocation method.

Findings

A remarkable change in fluid flow and heat transfer is noted if the MS location is close to the left sinusoidally heated wall. In particular, the average Nusselt number is the smallest for the middle centered partial MF through the left wall at a large Hartmann number.

Research limitations/implications

RBF collocation approach is limited to small geometries due to the obtained solution globally in the entire domain of the problem.

Practical implications

If the partial restriction of the effect of MF is done in real life, it would be a control parameter at some required/requested areas of the concerned problem.

Social implications

This is a physical problem.

Originality/value

If the proposed idea of partial variable MF is able to be applied to a system in real life, it would be a good controller on fluid flow and heat transfer. RBF-based methods are also alternative numerical procedures to solve heat transfer and fluid flow problems.
A failure mode, effects and criticality analysis-based method for formwork assessment and selection in building construction
Authors: Abu Dabous Saleh , Zadeh Tareq , Ibrahim Fakhariya
Published: July 2022

Purpose

This study aims at introducing a method based on the failure mode, effects and criticality analysis (FMECA) to aid in selecting the most suitable formwork system with the minimum overall cost.

Design/methodology/approach

The research includes a review of the literature around formwork selection and analysis of data collected from the building construction industry to understand material failure modes. An FMECA-based model that estimates the total cost of a formwork system is developed by conducting a two-phased semi-structured interview and regression and statistical analyses. The model comprises material, manpower and failure mode costs. A case study of fifteen buildings is analysed using data collected from construction projects in the UAE to validate the model.

Findings

Results obtained indicate an average accuracy of 89% in predicting the total formwork cost using the proposed method. Moreover, results show that the costs incurred by failure modes account for 11% of the total cost on average.

Research limitations/implications

The analysis is limited to direct costs and costs associated with risks; other costs and risk factors are excluded. The proposed framework serves as a guide to construction project managers to enhance decision-making by addressing the indirect cost of failure modes.

Originality/value

The research proposes a novel formwork system selection method that improves upon the subjective conventional selection process by incorporating the risks and uncertainties associated with the failure modes of formwork systems into the decision-making process.
How do consumers select between hotels and Airbnb? A hierarchy of importance in accommodation choice
Authors: Mody Makarand Amrish , Jung Sean , Dogru Tarik , Suess Courtney
Published: July 2022

Purpose

The purpose of this study is to examine the impact of key decision-making attributes on consumers’ choice of accommodation among and between hotels and Airbnb.

Design/methodology/approach

The study used a choice-based conjoint approach using 21 key decision-making factors that impact consumers’ choice of accommodation across five segments ranging from economy to luxury. Latent class estimation was used to identify segments of respondents who tend to have similar preferences for accommodation.

Findings

The results showed the presence of a consistent pattern of decision-making across the five accommodation segments, culminating in a hierarchy of importance in accommodation choice. The 21 key decision-making attributes comprised three tiers in order of decreasing importance: quality and service, amenities, and accessibility and safety. Further, latent class analysis indicated the presence of a hotel group and an Airbnb group of customers, which allowed us to identify how both types of providers might maximize the value of their offers to encourage customer switch.

Research limitations/implications

The accommodation landscape is extremely dynamic (particularly as the COVID-19 pandemic unfolds) and complex. The present study cannot capture all of its intricacies but provides an invaluable foundation for future research on the topic of consumer choice in an evolving and competitive accommodation market.

Originality/value

Extant research on accommodation choice has focused on hotels or Airbnb only. Moreover, research that has considered both types of accommodation simultaneously is limited in its conceptual and methodological scope. The present study synthesizes the fragmented literature on consumers’ accommodation choices and offers a holistic and coherent schematic – the hierarchy of importance in accommodation choice – that can be used by future researchers and practitioners alike.
Stock price crash risk and the adoption of poison pills: evidence from Brazil
Authors: Azevedo Yuri Gomes Paiva , Schwarz Lucas Allan Diniz , Gomes Hellen Bomfim , Ambrozini Marcelo Augusto
Published: July 2022

Purpose

The purpose of this paper is to examine the effect of stock price crash risk on the adoption of poison pills.

Design/methodology/approach

The authors estimate logit and probit regressions. Their sample includes 185 Brazilian public firms for the period 2010–2018. Following previous studies, the authors use the negative skewness of firm-specific weekly returns and the down-to-up volatility of firm-specific weekly returns as measures of firm's stock price crash risk. As proxies of poison pills, the authors employ the “conventional” poison pills in their baseline models and the “eternity” poison pills, which prevent the removal of poison pills from bylaws, in additional models.

Findings

The authors find that stock price crash risk measures are not associated with poison pill adoption. However, although stock price crash risk does not lead to poison pill adoption as a complementary corporate governance mechanism that protects firms against hostile takeover attempts, further results show that managers do not draw on stock price crash risk as a pretext to entrench themselves. Additional analyses also highlight that CEO power seems to play a role in moderating the relationship between stock price crash risk and eternity poison pill adoption.

Originality/value

The authors contribute to the literature on stock price crash risk, which calls for research in international contexts to better understand the effect of stock price crash risk on country-specific idiosyncratic features. The authors discuss a controversial anti-takeover mechanism that has been debated by Brazilian policymakers.
The impact of gender and political embeddedness on firm performance: evidence from China
Authors: Teng Ying , Gimmon Eli , Heilbrunn Sibylle , Song Shenyi
Published: July 2022

Purpose

This study explored the mediating effect of political embeddedness on the relationship between gender and performance of private enterprises in the emerging economy of China. Political embeddedness is examined in terms of personal characteristics of owners and their firm.

Design/methodology/approach

Secondary data were collected from the Chinese Private Enterprises Survey for the years 2002, 2006, 2014 and 2016 using responses to identical questions. Tobit models were implemented to examine hypotheses related to the gender gap. A bootstrapping approach was applied to examine hypotheses related to mediation through political embeddedness.

Findings

The gender effect on enterprise performance was found to be partially mediated by political embeddedness at the personal level and even more strongly by political embeddedness at the firm level, which is beyond the well-known mediation effect of bank loans.

Research limitations/implications

The Chinese sample, in which guanxi plays a significant role with respect to women-led firms, may limit the generalizability of the findings to other emerging economies.

Practical implications

Given the mediating effects on firm performance of political embeddedness at the personal and firm levels, women business owners in China should pursue political involvement, possibly with the support of policymakers and mentors.

Originality/value

The relationship between businesswomen and political embeddedness is underexplored. This study innovates by applying the gender lens to the notion of political embeddedness and extending the construct of personal political embeddedness to the firm level.
TQM model based on Deming prize for schools
Authors: Alauddin Nursuhana , Yamada Shu
Published: July 2022

Purpose

This paper aims to develop a total quality management (TQM) model based on the Deming prize criteria extracted from the Deming Prize. The proposed model is aligned with the school education context and deployed with the goal of achieving school excellence.

Design/methodology/approach

The model is developed based on a literature review in which key concepts for formulating the criteria and sub-criteria were identified. A qualitative research approach is applied to validate the model’s effectiveness. Interviews and feedback from an international school in Japan which adopted the model are used to determine its impact.

Findings

The model emphasises the achievement of school objectives (A) by implementing TQM activities (B) and assessing their impact (C). Its implementation offers enhanced organisational ability and the achievement of society-oriented school objectives. The findings show that the model gives clarity to TQM application and offers benefits for schools’ future sustainability.

Originality/value

This research proposes the adoption of a TQM model for educational institutions based on Deming criteria. Based on a comparison with prescriptive models such as Malcolm Baldrige National Quality Award and ISO 9001, this study shows how the developed model ensures organisational ability in current practice and future growth towards school excellence. Through the formulation of society-oriented school objectives and their linkage with results, it enables schools to create a balanced recognition of important stakeholders and gain consensus in realising the school’s objectives.
State-of-the-art review of the reliability evaluation of concrete beams exposed to fire
Authors: Coelho Tulio , Diniz Sofia , Rodrigues Francisco , Van Coile Ruben
Published: July 2022

Purpose

This paper aims to investigate the state of the art for the reliability evaluation of reinforced concrete beams in a fire situation. Special emphasis is placed on addressing which parameters were considered probabilistically or deterministically, the prescribed probabilistic models for the assumed stochastic variables, the treatment of the heat transfer mechanism, the quantification of the structural fire performance and the assumed target reliability levels.

Design/methodology/approach

Research papers were identified through a search on the Web of Science, Google Scholar and detailed searches within the journals Journal of Structural Fire Engineering, Fire Technology and Fire Safety Journal, supplemented with references known by the authors.

Findings

Considering the state-of-the-art review, gaps in the literature are identified related to (1) the probabilistic evaluation of shear capacity for standard fires and parametric fires, and bending capacity for parametric fires, (2) the absence of reference fragility curves for immediate design application/code calibration and (3) the specification of target safety levels for reliability-based design.

Originality/value

The lack of research papers gathering studies on the reliability of reinforced concrete beams in fire situation makes it difficult to further develop research in the area. The value of this work lies precisely in the collection of the basic information, making it possible to identify gaps to be addressed in future research and the suggestion of a research framework.
Job training satisfaction and knowledge sharing in IT company: a case study
Authors: Buonomo Ilaria , Piccinini Marco , Benevene Paula , Blasutig Gabriele , Cervai Sara
Published: July 2022

Purpose

This research aims to understand whether and how the perceptions that employees build and share over time about training activities and opportunities at work are linked to the knowledge management processes within the organization. This study aims at measuring how different levels of job training satisfaction are linked to employee perceptions of knowledge-sharing (KS) practices at work.

Design/methodology/approach

A total of 179 employees from an information and technology firm in Italy took part in the study, by completing questionnaires on job training satisfaction, KS practices and job-related variables (i.e. years of experience, hours of training in the previous year, job role and organizational area of belonging).

Findings

Findings showed that high job training satisfaction is related to positive perceptions of KS practices, so that when employees are satisfied with their job training experiences, they are more likely to value and recognize those practices.

Research limitations/implications

The relation between job training satisfaction and KS practices needs to be extended to different sectors and organizations to be generalized.

Social implications

Training activities within the organization are at the core of knowledge management practices and constitute a main source of sustainable competitive advantage; human resource management should reconsider the importance of monitoring training perceptions inside the organization, to become more conscious of the value and impact of these practices, in particular about training strategies.

Originality/value

Although great attention has been given to single-training satisfaction, only few studies consider the wider impact of job training satisfaction and its possible impact on knowledge sharing.
Egyptian physicians' information-seeking behavior while serving in public isolation hospitals for coronavirus patients
Authors: Mansour Essam , Shehata Ahmed , Farrag Abdelrahman
Published: July 2022

Purpose

The purpose of this study is to explore the information-seeking behavior of Egyptian physicians serving in COVID-19 isolation hospitals.

Design/methodology/approach

A sample of 91 physicians serving in Egyptian isolation hospitals answered the study questionnaire.

Findings

Demographically, more than half of respondents were males. Over one-third of them are holding Doctor of Medicine (M.D), followed by one-third holding Master of Medicine (MMed). Respondents' age ranged from 30 to 60 years. Internal medicine is the most common specialty, accounting for nearly half of all physicians, followed by chest medicine and intensive care medicine. The information-seeking behavior of these three groups in their regular work is believed to be different, but since all of the participants are working in COVID-19 isolation hospitals, they should have the same information resources, Internet access and the same needs relevant to COVID-19 in order to make accurate clinical decisions. The physicians used traditional and electronic information sources to fulfill their information needs, the most important of which were to make a specific research, find an answer to a specific case, and deliver a medical lecture. Colleagues, coworkers, nurses and pharmacists were the most important channels pursued by Egyptian physicians to obtain information.

Originality/value

This study is the first study that focuses on investigating the information-seeking behavior of Egyptian physicians serving in isolation hospitals. Any findings resulted from this study may serve as a noteworthy reference that may be useful to the Egyptian health sector, experts, researchers, as well as policymakers in establishing strategic decisions for making the understating much better.

Rethinking business transformation: how multiple technologies interact with intelligent workflows to produce exponential value
Authors: Dencik Jacob , Marshall Anthony
Published: July 2022

Purpose

IBM IBV research shows that interactions between several new digital technologies and between these technologies and other organizational capabilities enable and drive the business value needed for successful transformation.

Design/Methodology/Approach

Organizations should first identify the high value workflows and focus on what it takes to transform them.

Findings

IBM IBV analysis found that if an organization excels at implementing four key elements of transformation together with an integrated set of digital technologies, the revenue impact of a dollar invested is as much as 13 times greater than the revenue impact of a single technology such as cloud alone.

Practical/implications

Workflows provide an end-to-end perspective of what scaled transformation will look like while enabling identification of appropriate areas of immediate transformation.

Originality/Value

This paper especially valuable to practitioners and academics because it is sourced from multiple recent large-scale C-suite executive surveys conducted by the IBM Institute for Business Value, working in collaboration with Oxford Economics.

Published: July 2022

This paper investigates the determinants of venture capital investments across 25 African countries over the period 2014–2019. In particular, it considers the significance of innovation and digitalization in Africa's venture capital activity. The results show that digital infrastructure, high‐technology exports, internet coverage, market size, minority investor protection and government effectiveness are the main drivers of venture capital deals in Africa over the period examined. More generally, these findings highlight that digital infrastructure and connectivity, innovation and institutional frameworks all play an important role in shaping a favorable environment to attract venture capital funding.
Subjective poverty and migration intention abroad: The case of Senegal
Authors: Diallo Mamadou Abdoulaye
Published: July 2022

Based on data from Round 7 of the Afrobarometer survey, this study aims to identify the factors associated with Senegalese adults’ migration intention and investigates the effect of poverty on migration intention. We construct a subjective poverty index via multiple correspondence analysis and estimate a logistic regression model to identify the determinants of migration intention. The results show that poverty has a positive and significant effect on migration intention. Meanwhile, migration intention decreases with age, yet increases with both the level of dependence on remittances and the presence of a returned migrant in the household. Our results are policy relevant, as knowledge and understanding of the intention to migrate and its determinants can be used to assess and design future migration programs through the creation of employment opportunities and better working conditions to reduce poverty, remittances dependency, and potential brain drain, especially among youth and full/part‐time workers.
Palm‐based cellulose nanofiber isolated from mechano‐chemical processing as sustainable rheological modifier in reduced fat mayonnaise
Authors: Lee Zu Jia , Tong Shi‐Cheng , Tang Teck‐Kim , Lee Yee‐Ying
Published: July 2022

Reducing fat intake from our daily diet serves to be an effective way to combat the rising obesity issue worldwide. Hence, reducing fat content in mayonnaise, a high fat food product, is one of the primary trends in the food industry. To date, research on the use of nanocellulose, a new and emerging form of fat mimetic, in mayonnaise formulation remains limited. This study sets out to formulate reduced fat 5%, 15%, and 30% mayonnaise using varying concentration of nanocellulose synthesized from palm pressed fiber followed by a 20‐day stability study. Nanocellulose was synthesized with particle size of 106.0 ± 18.7 nm and zeta potential of −72.5 ± 2.26 mV. It was used as fat mimetic in mayonnaise. Rheological analysis conducted showed that incorporation of nanocellulose into reduced fat mayonnaise formulation was able to counteract the loss of viscosity in mayonnaise caused by fat content reduction. This finding was further supported by the smaller oil droplets that are closely packed in reduced fat mayonnaise formulation when viewed under light microscope. Nonetheless, significant oil droplet coalescence was found in reduced fat mayonnaise formulations during storage period which could lead to loss of viscosity. Taken together, these findings suggest that CNF was able to act as fat mimetic upon formulation of mayonnaise but the same cannot be said during long term storage of mayonnaise.

Practical Application

We successfully isolated nanocellulose from palm biomass (palm pressed fiber) using green approach and used it as a fat replacer for preparation of 5%, 15%, and 30% reduced fat mayonnaise. A computation study revealed a strong binding affinity of the nanocellulose on the lipase active site essential to inhibit the digestion of fats and oils. Therefore, nanocellulose demonstrated a huge potential to be used as not only as fat replacer but also rheological modifier for the development of reduced fat or vegan foods.

Authors: Nasir Bushra Farah , Kisely Stephen , Hides Leanne , Brennan‐Olsen Sharon , Kondalsamy‐Chennakesavan Srinivas , Nicholson Geoffrey C. , Gill Neeraj S. , Beccaria Gavin , Toombs Maree
Published: July 2022

Note: We respectfully refer to Aboriginal and Torres Strait Islander people as Indigenous in this study.

Objective

To design and develop an Indigenous specific suicide intervention skills program that focuses on education and intervention training as an effective suicide prevention strategy.

Method

Using a co‐designed wrap‐around framework, we developed a program in collaboration with >90 communities, stakeholders and service providers across Australia to understand knowledge, awareness and sense of connectedness between at‐risk groups and health services or support groups.

Results

The I‐ASIST training provides participants with the necessary skills and knowledge to apply a suicide intervention model. The framework behind the intervention model provides caregivers the awareness to recognise when someone may be at risk of suicide. It then gives them the skills to connect with a person at risk of suicide and to understand and clarify that risk, steps to keep that person safe for a specific period and then provide them with the resources or links required for further help. The program enables the development of knowledge through interactive strategies through cultural recognition and empowerment of participants. Based on a social‐enterprise model, I‐ASIST has been translated into a certified program supported by LivingWorks Australia.

Conclusion

Based on a strengths‐based and self‐determination model of co‐design, this grass roots innovative framework creates suicide safer communities.
Greenwash and green brand equity: The mediating role of green brand image, green satisfaction and green trust and the moderating role of information and knowledge
Authors: Ha Minh‐Tri , Ngan Vo Thi Kim , Nguyen Phuong N. D.
Published: July 2022

This work examines the impact of greenwash on green brand equity and analyses the mediation effects of green brand image, green satisfaction and green trust as well as the moderating effect of information and knowledge based on the legitimacy theory and signalling theory. This study adopts a questionnaire‐based survey design to gather data from 445 respondents using a cluster random sampling technique. Data collection focuses on Vietnamese consumers who had purchased electronic products in Ho Chi Minh City, Vietnam. The findings show that although greenwash is not significantly related to green brand equity possibly due to the halo effect, greenwash is adversely related to green brand image, green satisfaction and green trust, which would positively influence green brand equity. In other words, green brand image, green satisfaction and green trust play a full mediation role in the relationship between greenwash and green brand equity. In addition, information and knowledge actually moderate the relationship between greenwash and green brand equity, and it strengthens the adverse relationship between greenwash and green brand equity. This research is the first to combine green brand image, green satisfaction and green trust as mediators to shed light on the understanding of different impact mechanisms in the greenwash–green brand equity relationship. Furthermore, this research is also the first to study information and knowledge as a moderator in the greenwash–green brand equity relationship. This provides a better insight into the process and context by which greenwash affects green brand equity. Taken together, the findings of this study extend and advance the understanding regarding the different mechanisms and the dynamics in which green brand image, green satisfaction, green trust as mediators and information and knowledge as a moderator can play in the emerging market context of consumers of electronic products in Vietnam. The findings enrich the growing body of green marketing literature and contribute significantly towards a unified theory of brand equity.
Prioritizing Candidate Peptides for Cancer Vaccines Through Predicting Peptide Presentation by HLA-I Proteins
Authors: Zhou Laura Y. , Zou Fei , Sun Wei
Published: July 2022

Cancer (treatment) vaccines that are made of neoantigens, or peptides unique to tumor cells due to somatic mutations, have emerged as a promising method to reinvigorate the immune response against cancer. A key step to prioritizing neoantigens for cancer vaccines is computationally predicting which neoantigens are presented on the cell surface by a human leukocyte antigen (HLA). We propose to address this challenge by training a neural network using mass spectrometry (MS) data composed of peptides presented by at least one of several HLAs of a subject. We embed the neural network within a mixture model and train the neural network by maximizing the likelihood of the mixture model. After evaluating our method using data sets where the peptide presentation status was known, we applied it to analyze somatic mutations of 60 melanoma patients and identified a group of neoantigens more immunogenic in tumor cells than in normal cells. Moreover, neoantigen burden estimated by our method was significantly associated with a measurement of the immune system activity, suggesting these neoantigens could induce an immune response.

Authors: Afacan Nazife Nur , Coşkun Zerrin Özergin , Çeliker Metin , Erdivanlı Özlem Çelebi , Terzi Suat , Dursun Engin
Published: July 2022

Objectives

The objectives of this study were to evaluate and compare the test–retest reliability of acoustic parameters (jitter [%], shimmer [%], noise‐to‐harmonic ratio [NHR], and voice turbulence index [VTI]) by using multidimensional voice program, and to detect the discriminatory power of the acoustic measures with respect to dysphonic voices and normal voices.

Design, Setting, Participants, and Methods

Fifty‐four (25 male and 29 female) participants with voice disorders and fifty‐one (27 male and 24 female) participants with normal voices were enrolled in this study. They were assessed by anamnesis, visual examination, auditory perceptual assessment (GRBAS), and acoustic measurements. The intraclass correlation coefficient was used to determine the test–retest reliability. The effect size (d value) and p value obtained from the t‐test were used to determine the discriminatory power.

Results

In the normal group, good reliability was observed for jitter, shimmer, and NHR, and moderate reliability was observed for VTI. With regard to the dysphonic group, jitter, shimmer, and VTI were moderately reliable, and the NHR had good reliability. Meanwhile, the discriminatory powers of jitter and shimmer were evaluated as ‘medium’, and those of NHR and VTI as ‘small’.

Conclusion

The reliability and discriminatory powers of our acoustic measures were high compared with most other studies. Their level of reliability and discriminatory power can be maximised by using stringent rules. However, attaining an excellent level of reliability and discriminatory seems infeasible power owing to the variable characteristic of voice. Therefore, acoustic measures should be adopted as a complementary tool.
The utility of liver function tests and abdominal ultrasound in infectious mononucleosis—A systematic review
Authors: Tan E Tian , Wilkinson Danielle , Edafe Ovie
Published: July 2022

Introduction

A large proportion of patients with infectious mononucleosis (IM) have abnormal liver function tests (LFT) at presentation. There is no guideline regarding the management and follow‐up of these patients. Some patients also have abdominal ultrasound (US) due to deranged LFT, the need for this practice is unclear. The aim of this systematic review was to evaluate the evidence base on LFT assessment in IM, time to resolution of derangement, and the role of abdominal US.

Methods

A systematic search of PubMed, EMBASE and the Cochrane library was done. Two authors independently screened records for eligibility using pre‐defined criteria. We included both adult and paediatric populations. Quality assessment of included studies was done.

Results

A total of 3924 patients were included from 32 studies, of which LFT values were reported on 2779 patients. A combination of typical clinical features, heterophile antibodies and Epstein–Barr virus‐specific antibodies were used to ascertain diagnosis. The following proportion of patients had abnormal LFT: aspartate transaminase (57%); alanine transaminase (62%); alkaline phosphatase (65%); bilirubin (16%); gamma‐glutamyltransferase (41%). Reported median (interquartile range) time to resolution of LFT was 8 (6–12) weeks (n = 438). Maximum time to resolution was >6 months. Clinical hepatomegaly and splenomegaly were found in 35% and 44% of patients, respectively. Enlarged liver and spleen on US were seen in 16 of 29 and 38 of 38 of patients, respectively. There were no reports of decompensated liver disease.

Conclusion

Current evidence questions the need for routine assessment of LFT in immunocompetent patients presenting with IM; serial LFT assessments following initial abnormalities are not required in immunocompetent patients with subclinical derangement of LFT; routine US abdomen in IM to evaluate for derangement of LFT is not required.
Informing employees in small and medium‐sized firms about training: Results of a randomized field experiment

We mailed brochures to 10,000 randomly chosen employed German workers who were eligible for a subsidized occupational training program called WeGebAU, informing them about the importance of skills‐upgrading training in general and about WeGebAU in particular. Using survey and register data, we estimate effects of the informational brochure on awareness of the program, on take‐up of WeGebAU and other training, and on subsequent employment. The brochure more than doubles awareness of the program. There are no effects on WeGebAU take‐up, but participation in other (unsubsidized) training increases among employees aged under 45. Short‐term labor market outcomes are not affected.
Women's work and wages in the sixteenth century and Sweden's position in the ‘little divergence’
Authors: Molinder Jakob , Pihl Christopher
Published: July 2022

We use a unique source from the Swedish royal demesnes to examine the work and relative wages of women in sixteenth‐century Sweden, an economic laggard in the early modern period. The source pertains to workers hired on yearly contracts, a type more representative of historical labour markets than day labour on large construction sites, and this allows us to observe directly the food consumed by workers. We speak to the debate on the ‘little divergence’ within Europe, as women's work and gender differentials in pay is a key indicator of women's relative autonomy and seen as a cause for the economic ascendency of the North Sea region during the period. We find small gender differentials among both unskilled and skilled workers, indicating that Sweden was a part of the ‘golden age’ for women. We argue that despite superficial equality, women's economic outlooks were restrained in many other ways – including their access to higher‐skilled work and jobs in the expanding parts of the economy – adding important nuance to the discussion about the relationship between women's social position and economic growth in the early modern period.
Predicting the suitable fertilizer for crop based on soil and environmental factors using various feature selection techniques with classifiers

Agriculture is an essential part of human life. The crop productivity is based on the soil and environmental factors. Different crops are cultivated in different areas. Nowadays, the crop productivity level is affected by the climate change and diseases in the crops. Due to this pest infestation, the crop growth is heavily affected. To overcome this problem, the right fertilizer for a particular crop has to be chosen and fertilizer helps farmers to improve the crop productivity rate. This process can be done by using various machine learning techniques. In this work, various features selection techniques with classifiers used to predict the suitable fertilizer for a crop. The experimental results show that recursive feature elimination along the proposed Heterogeneous Stacked Ensemble classifier gives better prediction rate than other methods.

The Challenge

The Challenge Statement: The inclusion of culturally and linguistically diverse (CLD) students is rarely addressed in Chinese Language Education. What is the potential of Chinese classrooms as sites for the inclusion of CLD students? This article presents findings from a systematic review and suggests a path forward for a more culturally responsive Chinese Language Education.
