Frameshifting at collided ribosomes is modulated by elongation factor eEF3 and by Integrated Stress Response regulators Gcn1 and Gcn20
Authors: Houston Lisa , Platten Evan , Connelly Sara , Wang Jiyu , Grayhack Elizabeth J.
Published: August 2021

Ribosome stalls can result in ribosome collisions that elicit quality control responses, one function of which is to prevent frameshifting by the stalled ribosome, an activity that entails interaction of the conserved yeast protein Mbf1 with uS3 on colliding ribosomes. However, the full spectrum of factors that mediate frameshifting during ribosome collisions is unknown. To delineate such factors in the yeastSaccharomyces cerevisiae, we used genetic selections for mutants that either suppress or increase frameshifting from a known ribosome stall site, CGA codon repeats. We show that the general translation elongation factor eEF3 promotes frameshifting, while Integrated Stress Response (ISR) pathway components Gcn1 and Gcn20 suppress frameshifting. We found a mutant form of eEF3 that specifically suppressed frameshifting, but not translation inhibition by CGA codons. Thus, we infer that frameshifting at collided ribosomes requires eEF3, which facilitates tRNA-mRNA translocation and E-site tRNA release in yeast and other single cell organisms. By contrast, we found that removal of either Gcn1 or Gcn20, which bind collided ribosomes with Mbf1, increased frameshifting. Thus, we conclude that frameshifting is suppressed by Gcn1 and Gcn20, although these effects are not mediated through activation of the ISR. Furthermore, we examined the relationship of eEF3-mediated frameshifting to other quality control mechanisms, finding that the eEF3-mediated frameshifting competes with No-Go decay, Mbf1 and Gcn1/20. Thus, these results provide evidence of a direct link between translation elongation and frameshifting at collided ribosomes, as well as evidence that frameshifting competes with other quality control pathways that act on collided ribosomes.
Using herbarium samples for NGS methods – a methodological comparison
Authors: Marinček Pia , Wagner Natascha D. , Tomasello Salvatore
Published: August 2021

Herbaria harbor a tremendous amount of plant specimens that are rarely used for plant systematic studies. The main reason is the difficulty to extract a decent quantity of good quality DNA from the preserved plant material. While the extraction of ancient DNA in animals is well established, studies including old plant material are still underrepresented. In our study we compared the standard Qiagen DNeasy Plant Mini Kit and a specific PTB-DTT protocol on two different plant genera (Xanthium L. and Salix L.). The included herbarium material covered about two centuries of plant collections. A selected subset of samples was used for a standard library preparation as well as a target enrichment approach. The results revealed that PTB-PTT resulted in higher quantity and quality regarding DNA yield. For relatively recent herbarium specimens, and despite the lower overall yield of DNA, the Qiagen Kit resulted in better sequencing results regarding the number of filtered and mapped reads. We were able to successfully sequence a sample from 1820 and conclude that it is possible to include old herbarium specimens in NGS approaches. This opens a treasure box for phylogenomic research.

Published: August 2021

Listeria monocytogenesis a facultative anaerobe which can cause a severe food-borne infection known as listeriosis. Rhamnose is a deoxyhexose sugar abundant in a range of environments, including the human intestine, and can be degraded byL. monocytogenesin aerobic and anaerobic conditions into lactate, acetate and 1,2-propanediol. Our previous study showed that addition of vitamin B12 stimulates anaerobic growth ofL. monocytogeneson rhamnose due to the activation of bacterial microcompartment (BMC)-dependent 1,2-propanediol utilization with concomitant production of propionate and propanol. Notably, anaerobic propanediol metabolism has been linked to virulence of enteric pathogens includingSalmonellaspp. andL. monocytogenes. In this study we investigate the impact of B12 on aerobic and anerobic growth ofL. monocytogeneson rhamnose, and observed growth stimulation andpduBMC activation only in anaerobically grown cells with B12 added to the medium. Comparative Caco-2 virulence assays, showed that thesepduBMC induced cells have significantly higher translocation efficiency compared to aerobically grown cells (without and with added B12) and non-induced anaerobically grown cells, while adhesion and invasion capacity is similar for all cells. Comparative proteomics analysis showed specific and overlapping responses linked to metabolic shifts, activation of stress defense proteins and virulence factors, with RNA polymerase sigma factor SigL; teichoic acids export ATP-binding protein, TagH; DNA repair and protection proteins RadA and DPS; and glutathione synthase GshAB previously linked to activation of virulence response inL. monocytogenes, uniquely upregulated in anaerobically rhamnose grownpduBMC induced cells. Our results shed new light into B12 impact onL. monocytogenescompetitive fitness and virulence.
Sex differences in deleterious genetic variants in a haplodiploid social insect
Authors: Miller Sara E. , Sheehan Michael J.
Published: August 2021

Deleterious variants are selected against but can linger in populations at low frequencies for long periods of time, decreasing fitness and contributing to disease burden in humans and other species. Deleterious variants occur at low frequency but distinguishing deleterious variants from low frequency neutral variation is challenging based on population genetics data. As a result, we have little sense of the number and identity of deleterious variants in wild populations. For haplodiploid species, it has been hypothesized that deleterious alleles will be directly exposed to selection in haploid males, but selection can be masked in diploid females due to partial or complete dominance, resulting in more efficient purging of deleterious mutations in males. Therefore, comparisons of the differences between haploid and diploid genomes from the same population may be a useful method for inferring rare deleterious variants. This study provides the first formal test of this hypothesis. Using wild populations of Northern paper wasps (Polistes fuscatus), we find that males have fewer overall variants, and specifically fewer missense and nonsense variants, than females from the same population. Allele frequency differences are especially pronounced for rare missense and nonsense mutations and these differences lead to a lower genetic load in males than females. Based on these data we estimate that a large number of highly deleterious mutations are segregating in the paper wasp population. Stronger selection against deleterious alleles in haploid males may have implications for adaptation in other haplodiploid insects and provides evidence that wild populations harbor abundant deleterious variants.
On incoherent diffractive imaging
Authors: Lohse Leon M. , Vassholz Malte , Salditt Tim
Published: August 2021

Incoherent diffractive imaging (IDI) promises structural analysis with atomic resolution based on intensity interferometry of pulsed X-ray fluorescence emission. However, its experimental realization is still pending and a comprehensive theory of contrast formation has not been established to date. Explicit expressions are derived for the equal-pulse two-point intensity correlations, as the principal measured quantity of IDI, with full control of the prefactors, based on a simple model of stochastic fluorescence emission. The model considers the photon detection statistics, the finite temporal coherence of the individual emissions, as well as the geometry of the scattering volume. The implications are interpreted in view of the most relevant quantities, including the fluorescence lifetime, the excitation pulse, as well as the extent of the scattering volume and pixel size. Importantly, the spatiotemporal overlap between any two emissions in the sample can be identified as a crucial factor limiting the contrast and its dependency on the sample size can be derived. The paper gives rigorous estimates for the optimum sample size, the maximum photon yield and the expected signal-to-noise ratio under optimal conditions. Based on these estimates, the feasibility of IDI experiments for plausible experimental parameters is discussed. It is shown in particular that the mean number of photons per detector pixel which can be achieved with X-ray fluorescence is severely limited and as a consequence imposes restrictive constraints on possible applications.

Published: August 2021

The asymmetric unit of the title compound, C16H14Cl2N2O, comprises two similar molecules, A and B, in which the dihedral angles between the two aromatic rings are 70.1 (3) and 73.2 (2)°, respectively. The crystal structure features short C—H...Cl and C—H...O contacts and C—H...π and van der Waals interactions. The title compound was refined as a two-component non-merohedral twin, BASF 0.1076 (5). The Hirshfeld surface analysis and two-dimensional fingerprint plots show that H...H (38.2% for molecule A; 36.0% for molecule B), Cl...H/H...Cl (24.6% for molecule A; 26.7% for molecule B) and C...H/H...C (20.0% for molecule A; 20.2% for molecule B) interactions are the most important contributors to the crystal packing.
Consumers’ attitudes, perceived risks and perceived benefits towards repurchase intention of food truck products
Authors: Loh Zeyen , Hassan Siti Hasnah
Published: August 2021

Purpose

This study aims to determine the repurchase intention of food truck products based on perceived risks and perceived benefits by consumers within the context of Malaysia. Recently, the food truck industry has been expanding as customers begin to explore alternatives for food convenience. However, there are not many studies carried out on this topic, especially in Asian countries. This study will fill the gaps on the factors that affect repurchase intention, especially perceived risks and perceived benefits of food trucks products.

Design/methodology/approach

A cross-sectional online survey was conducted through Facebook Messenger and WhatsApp on consumers with prior experience in buying food truck products. The partial least square (PLS) modelling using the SmartPLS software was employed to analyse the data.

Findings

The results from 294 food truck consumers showed that perceived benefit, food safety, attitude and subjective norm significantly influence food truck products' repurchase intention. On the other hand, perceived risk towards the environment and perceived behavioural control do not substantially affect food truck products' repurchase intention.

Research limitations/implications

The data collected were related only to the food trucker's customer that operates in Malaysia. Thus, the results might be only applicable to similar other Asian or developing countries.

Practical implications

The results provided some managerial indicators to improve the level of business efficiency among food truck operators. Besides, marketers and policymakers can develop effective strategies and policies based on this study to develop this industry further.

Originality/value

The study gives a fresh overview of how the food truck business can improve its services in developing countries. The results offer a competitive advantage and how to strengthen customer retention that can improve business performance.
Line managers' perceptions of diversity management: insights from a social exchange theory perspective
Authors: Nachmias Stefanos , Mitsakis Fotios , Aravopoulou Eleni , Rees Christopher J. , Kouki Amairisa
Published: August 2021

Purpose

Drawing on the social exchange theory, this study aims to explore line managers' perceptions of diversity management, as well as their perceptions of their role and responsibilities in shaping and implementing diversity practices. The senior management's leadership support, as it is perceived by line managers, in assisting them to manage diversity successfully is also examined.

Design/methodology/approach

Semi-structured interviews with 51 line managers across different sectors in the UK were conducted to address the following three research questions. First, how do line managers perceive diversity management? Second, what are the actual roles and responsibilities of line managers in shaping diversity practices' implementation? Third, how do leadership interactions within the organisation influence line managers' perceptions of diversity practices?

Findings

Line managers present high levels of personal determination and commitment towards diversity supplemented by a consensus on the strategic role of leadership in relation to diversity management. In addition, poor levels of organisational support, leadership values and style are identified; all highly related to their ability to deliver results and, most importantly, to form effective relationships in the workplace.

Research limitations/implications

Data included line managers' views but not senior managers' perspectives, thus limiting the study in identifying the holistic impact of social exchanges in shaping effective relations. In addition, quantitative research could test and enhance the generalisability of existing findings.

Practical implications

Investing in social relationships can positively influence line managers' ability to deliver results. Action is required at the organisational level by senior management to support and recognise line managers' critical roles to enable them to apply and promote diversity management.

Originality/value

These findings address a theoretical gap relating to the evaluation of the critical role played by line managers in the delivery of diversity practices. The study further demonstrates how social exchange relationships can influence line managers' perceptions of diversity management, an unexplored area within the diversity literature.
Reducing tax identity theft by identifying vulnerability points in the electronic tax filing process
Authors: Ngugi Benjamin K. , Hung Kuo-Ting , Li Yuanxiang John
Published: August 2021

Purpose

Tax Identity Theft involves the illegal use of a potential taxpayer’s identity, usually the social security number, to fraudulently file a tax return and claim a refund. The victim is the real owner of the social security number who will have difficulties getting a tax refund, as the offender has already taken a refund for the year in question. This paper aims to investigate whether the increased use and adoption of electronic tax filing (i.e. E-Filing) technologies has inadvertently resulted in a corresponding growth in Tax Identity Theft.

Design/methodology/approach

Multiple regressions are used to analyze the data that is extracted from the Identity Theft complaint reports (maintained by the Federal Trade Commission) and the tax filing statistics (retrieved from the Internal Revenue Service).

Findings

The results indicate that E-Filing can indirectly but significantly increase Tax Identity Theft through the full mediation effects of individual Self-E-Filing and Direct Deposit adoption, after controlling for general Identity Theft, the number of Individual Tax Returns and Total Refunds.

Originality/value

The authors explore the association between the adoption of tax e-filing technologies and Tax Identity Theft. The findings suggest that the key loopholes in the Tax Identity Theft process are at the Self-E-Filing and the Direct Deposit points. Several practical recommendations for patching these loopholes are provided and discussed.
Hospitality employees’ emotions in the workplace: a systematic review of recent literature
Authors: Hwang YooHee , Shi Xiaolin (Crystal) , Wang Xingyu
Published: August 2021

Purpose

This systematic review synthesizes the recent literature (2010–2020) on hospitality employees’ emotions, affect and moods. This study has three objectives: to clarify the definitions of emotions, affect and moods; to explain how theories are integrated into understanding hospitality employees’ emotions, affect and moods; and to assess how emotions, affect and moods are measured.

Design/methodology/approach

Using seven major databases, the authors selected 61 peer-reviewed academic journal articles published in hospitality outlets for review. We based our study on five stages of conducting a systematic review: scoping, planning, identification, screening and eligibility.

Findings

Affect is an umbrella term encompassing moods and emotions. Emotions are distinct from emotion-laden constructs, such as emotional labor and emotional intelligence. Theories on conservation of resources, emotional labor and social exchange have been most frequently used to understand hospitality employees’ emotions. However, they overlooked the dynamic nature of emotions when using these theories. Hospitality researchers often used a subset of the positive and negative affect scale and did not discuss back-translation.

Practical implications

Hospitality employees’ emotions lead to far-reaching consequences in attitudes, intentions and behaviors in work and non-work domains. Effective practices (e.g. creating a supportive climate) that help evoke positive employee emotions and reduce negative employee emotions are thus desirable.

Originality/value

Our findings crystallize the understanding of emotions, affect and moods of hospitality employees. We further provide a roadmap for future research on hospitality employees’ emotions. Data triangulation, cross-cultural research and mixed emotions are novel opportunities for future research.
Does tourism affect house prices in Turkey? Evidence from smooth structural break tests
Authors: Yıldırım Mustafa Ozan , Karul Cagin
Published: August 2021

Purpose

The purpose of this study is to examine the impact of tourism activities on house prices in Turkey from January 2010 to March 2020.

Design/methodology/approach

It is used newly developed cointegration and causality tests based on Fourier approximation. These methods consider smooth structural breaks and do not need to recognize a priori date number and/or form of breaks.

Findings

Empirical findings show that international tourism activities have a substantial role in the escalation of house prices in Turkey. Findings also indicate a rise in industrial production enhances house prices while the mortgage lending rate exhibits a negative influence on house prices. Additionally, the evidence from Fourier causality tests reveals the unilateral causal linkage from tourism to house prices. This situation also shows that the tourism sector has a substantial role in stabilizing house prices’ rapid rise as a policy implication.

Originality/value

Although a large number of papers have been analyzing the link between house prices and macroeconomic variables, this study eliminates the lack of papers examining the link between tourism and house prices in Turkey by using the new cointegration and causality methods that consider smooth structural changes.
Auto-attentional mechanism in multi-domain convolutional neural networks for improving object tracking
Authors: Huang Jinchao
Published: August 2021

Purpose

Multi-domain convolutional neural network (MDCNN) model has been widely used in object recognition and tracking in the field of computer vision. However, if the objects to be tracked move rapid or the appearances of moving objects vary dramatically, the conventional MDCNN model will suffer from the model drift problem. To solve such problem in tracking rapid objects under limiting environment for MDCNN model, this paper proposed an auto-attentional mechanism-based MDCNN (AA-MDCNN) model for the rapid moving and changing objects tracking under limiting environment.

Design/methodology/approach

First, to distinguish the foreground object between background and other similar objects, the auto-attentional mechanism is used to selectively aggregate the weighted summation of all feature maps to make the similar features related to each other. Then, the bidirectional gated recurrent unit (Bi-GRU) architecture is used to integrate all the feature maps to selectively emphasize the importance of the correlated feature maps. Finally, the final feature map is obtained by fusion the above two feature maps for object tracking. In addition, a composite loss function is constructed to solve the similar but different attribute sequences tracking using conventional MDCNN model.

Findings

In order to validate the effectiveness and feasibility of the proposed AA-MDCNN model, this paper used ImageNet-Vid dataset to train the object tracking model, and the OTB-50 dataset is used to validate the AA-MDCNN tracking model. Experimental results have shown that the augmentation of auto-attentional mechanism will improve the accuracy rate 2.75% and success rate 2.41%, respectively. In addition, the authors also selected six complex tracking scenarios in OTB-50 dataset; over eleven attributes have been validated that the proposed AA-MDCNN model outperformed than the comparative models over nine attributes. In addition, except for the scenario of multi-objects moving with each other, the proposed AA-MDCNN model solved the majority rapid moving objects tracking scenarios and outperformed than the comparative models on such complex scenarios.

Originality/value

This paper introduced the auto-attentional mechanism into MDCNN model and adopted Bi-GRU architecture to extract key features. By using the proposed AA-MDCNN model, rapid object tracking under complex background, motion blur and occlusion objects has better effect, and such model is expected to be further applied to the rapid object tracking in the real world.
Lesson study as a way of improving school-day navigation for pupils with severe intellectual disability and autism
Authors: Klefbeck Kamilla
Published: August 2021

Purpose

This research explores lesson study as a way to enhance the quality of teaching for pupils with learning disabilities and autism spectrum disorder by observing changes to one pupil's (Wilma) active educational participation. The study also investigates if and in what ways the professional development impacted teaching practices.

Design/methodology/approach

Five teachers met with the author on four occasions. Between these meetings, the teachers delivered the lessons they had planned together. The author video recorded the meetings to discern how the teachers' expressions developed. The author shared their thoughts with another researcher to enable an interrater validity examination.

Findings

The implementation of the lesson study vehicle enabled the teachers to transform their thinking from mainly focusing on pupils' deficiencies to instead focusing on their strengths. A relationship was found between teachers' understanding of central coherence, their skills in adapting received instructions and pupils' abilities to process and contextualize information or discern the whole picture.

Research limitations/implications

Research that involves teachers in the learning process emphasizes the relation between teachers’ thinking and their potential to enable the contextualized inclusion of pupils with learning disabilities.

Originality/value

This research offers important insights into how school-day navigation for pupils with severe intellectual disability and autism can be understood through the lens of variation theory; the teachers' repeated and adjusted use of the frame on the schedule strip enabled Wilma to discern what would happen next during the school day.
Trace data visualisation enquiry: a methodological coupling for studying information practices in relation to information systems
Authors: Ekström Björn
Published: August 2021

Purpose

The purpose of this paper is to examine whether and how a methodological coupling of visualisations of trace data and interview methods can be utilised for information practices studies.

Design/methodology/approach

Trace data visualisation enquiry is suggested as the coupling of visualising exported data from an information system and using these visualisations as basis for interview guides and elicitation in information practices research. The methodology is illustrated and applied through a small-scale empirical study of a citizen science project.

Findings

The study found that trace data visualisation enquiry enabled fine-grained investigations of temporal aspects of information practices and to compare and explore temporal and geographical aspects of practices. Moreover, the methodology made possible inquiries for understanding information practices through trace data that were discussed through elicitation with participants. The study also found that it can aid a researcher of gaining a simultaneous overarching and close picture of information practices, which can lead to theoretical and methodological implications for information practices research.

Originality/value

Trace data visualisation enquiry extends current methods for investigating information practices as it enables focus to be placed on the traces of practices as recorded through interactions with information systems and study participants' accounts of activities.
Corporate social responsibility (CSR) and tax incentives: the case of Tunisian companies
Authors: Kacem Henda , Brahim Omri Mohamed Ali
Published: August 2021

Purpose

This paper aims to investigate the question concerning whether tax incentives motivate companies to be socially responsible. This study, specifically, examines the impact of tax incentives for corporate social responsibility (CSR) on the societal practices of Tunisian companies.

Design/methodology/approach

This study uses multiple regression models to assess the effectiveness of tax incentives for companies to take responsible actions. The study was conducted on 71 Tunisian companies operating in different sectors.

Findings

The results reveal that there is a negative and significant association between tax incentives and CSR practices. Therefore, there is an inefficient use of these types of incentives.

Practical implications

The results of the study have important implications for investors and regulatory basis wishing to enhance CSR by giving tax incentives. Investment in social responsibility may improve the corporate culture and reduce the conflict in companies.

Originality/value

The theoretical contributions relate mainly to the originality of the conceptual model developed, to the literature review and to the theoretical foundations mobilized. In fact, the originality of this research is justified by the scarcity of previous study dealing with the relationship between tax incentives and CSR. Thus, to the best of the authors’ knowledge, this study is one of the first to investigate the impact of tax incentives for CSR on CSR practices.
Transferring, translating and transforming knowledge: the role of brokering in healthcare networks
Authors: Williams Sharon J. , Radnor Zoe , Aitken James , Esain Ann , Matthias Olga
Published: August 2021

Purpose

This research examines how knowledge and information are managed within two care networks. We develop a conceptual framework drawing on the notion of brokering and the 3T framework, which is used to describe the relative complexity of boundaries (referred to in the framework as syntactic, semantic and pragmatic) as well as capabilities and processes required to exchange information within the network. Previous research on brokering has focused on healthcare managers and professionals, but this research extends to patients and caregivers. Understanding knowledge exchange and brokering practices in healthcare is critical to the delivery of effective services.

Design/methodology/approach

For this case research, non-participant observation and experienced-based interviews were undertaken with healthcare professionals, patients and caregivers within two care networks.

Findings

The findings reveal brokering roles occupied by healthcare professionals, patients and caregivers support the transfer, translation and transformation of knowledge and information across functional and organisational boundaries. Enablers and disablers to brokering and the exchange of knowledge and information are also identified.

Research limitations/implications

The study is limited to two care networks for long-term conditions within the UK. Further research opportunities exist to examine similar care networks that extend across professional and organisational boundaries.

Practical implications

This research informs healthcare professionals of the brokering capabilities that occur within networks and the enabling and disabling factors to managing knowledge across boundaries.

Originality/value

This paper provides a conceptual framework that categorises how increased levels of knowledge and information exchange and brokering practices are managed within care networks.
Islamic finance and economic growth nexus: an empirical evidence from Southeast Asia using dynamic panel one-step system GMM analysis
Authors: Ledhem Mohammed Ayoub , Mekidiche Mohammed
Published: August 2021

Purpose

This paper aims to empirically explore the nexus between Islamic finance and economic growth across Southeast Asia based on the perception of the endogenous growth model.

Design/methodology/approach

This paper applied the dynamic panel one-step system GMM as an optimum estimation approach to study the influence of Islamic finance on economic growth in Southeast Asia from 2013Q4 to 2019Q4. This paper used total Islamic financing as the major exogenous explanatory factor inside the endogenous growth model, whereas the gross domestic product was used as the measurement of economic growth. The sample consisted of all complete Islamic banks operating in Southeast Asia (Malaysia, Brunei Darussalam and Indonesia).

Findings

The findings demonstrated that Islamic finance is promoting economic growth in Southeast Asia, which reflects the weighty role of Islamic finance as an energetic contributor to economic growth.

Practical implications

This paper would enrich the literature by studying the nexus between Islamic finance and economic growth in Southeast Asia based on the perception of endogenous growth model, as the results of this paper assist as an attendant for financial scholars, decision-makers and policymakers to expand Islamic finance globally as an alternative funding source for the best involvement to economic growth.

Originality/value

Despite the existing studies on the nexus between Islamic finance and economic growth, this paper is the first that explores empirically the nexus between Islamic finance and economic growth in Southeast Asia based on the theoretical background of the endogenous growth model to obtain solid information on this nexus.
Young aspiring globals (YAGs): early-stage strategies of knowledge-focused international entrepreneurs
Authors: Brockman Paul , Dow Douglas , Phan Hoang Long , Rammal Hussain Gulzar , Zurbruegg Ralf
Published: August 2021

Purpose

This study aims to explore the intention–action relationship of small and medium-sized (SMEs) firms with knowledge capital that declare their intention to internationalize from their inception.

Design/methodology/approach

The authors apply the theory of planned behavior and hand-collect a database of Chinese born globals, purely domestic firms and traditional exporting firms. The authors’ hypothesis is that Chinese born globals [or young aspiring globals (YAGs)] will strive to acquire domestic and international patents at an early stage to institutionally protect their knowledge-capital via intellectual property rights as they enter the competitive global marketplace.

Findings

The results confirm that knowledge-focused YAGs apply for patents at an earlier stage than purely domestic and traditional exporting firms. However, in the long run, these firms are neither demonstrating increased knowledge capital by being more innovative nor producing more valuable innovations than their counterparts.

Originality/value

This study tests the intention–action relationship in the context of SMEs internationalization. It contributes to the internationalization literature by identifying the internationalization pattern of born globals (YAGs) from emerging markets and providing an explanation for what happens to these firms as they mature.
How to harnesses digital technologies for pursuing business model innovation: a longitudinal study in creative industries
Authors: Priyono Anjar , Darmawan Baziedy , Witjaksono Gunawan
Published: August 2021

Purpose

This study aims to investigate how manufacturing firms in the creative industries harness digital technologies to undertake business model innovation.

Design/methodology/approach

This study used in-depth case studies to examine the complex interplay between digital technologies and business model innovation. A longitudinal approach was selected to capture major events both within the firm and in the business environment. Building on the firm’s archival data, interviews and secondary data that was available to the public, the authors carefully analyzed impactful digital technology events and the firm’s responses to the technological changes that occurred over the period of 2004–2020.

Findings

The findings suggest that digital technologies alone are not sufficient for business model innovation to be successful; support from sociotechnical factors is also required. Additionally, firms should reinvent a new business model when the existing ones seem to start to diminish.

Research limitations/implications

In this study one firm was examined as the subject, using a qualitative method. This method allowed us to observe complex interplays among the resources required in business models. Future research can combine qualitative methods with computational case studies, which utilize a large volume of quantitative big data.

Practical implications

The results of this study suggest that managers must ensure that the resources within and outside organizations are loosely connected and are readily available to be mobilized for supporting business model innovation. To enable this, managers must prepare the required resources in advance.

Originality/value

The current findings add to a growing body of literature on business model innovation and digital technologies. In particular, this study describes the process of how a traditional firm from a least developed country pursues business model innovation with the support of digital technologies.

Consequently, this study theoretically x-rayed the various ways in which IoT could be applied to academic libraries and the expected challenges associated with the adoption of the technology.

Design/methodology/approach

This study used the review method to examine the application of IoT in contemporary academic libraries.

Findings

This study explained the concept of IoT and went further to x-ray the application of IoTs in academic libraries as it affects critical aspects of the library operations, thereby justifying how IoT influences innovative service delivery. The peculiar challenges faced by academic libraries in developing countries were also discussed.

Originality/value

This study’s value is reflected in the need to examine IoT adoption in academic libraries from the perspective of both developing and developed countries, where for certain reasons, the diffusion of new technology is relatively slow.
Recovery colleges in mental health-care services: an Australian feasibility and acceptability study
Authors: Hopkins Liza , Foster Andrew , Belmore Sue , Anderson Shelley , Wiseman Di
Published: August 2021

Purpose

This study aims to evaluate the feasibility and acceptability of establishing a recovery college in an Australian acute and community adult mental health service. Very little has been published on efforts to incorporate recovery colleges in inpatient settings other than forensic. This study offers an evaluation of feasibility and acceptability of this service model within a health-care setting.

Design/methodology/approach

Participant feedback and qualitative implementation data, from an acute mental health-care inpatient ward and adult community care were used. Participants were mental health service consumers and staff. The intervention involved a co-produced, co-designed, co-delivered and co-received educational opportunity for mental health consumers, carers, staff and the community.

Findings

Feedback from course participants indicates that learning objectives were met by the majority of participants, while stakeholders identified that establishing a recovery college within both the inpatient and community health-care service was feasible at a service level and broadly acceptable to consumers.

Originality/value

Establishing an adult recovery college in inpatient and community care is likely to be effective re-orientating mental health-care services as well as improving outcomes for consumers.
CSR motives on situational scepticism towards luxury brands
Authors: Teah Kevin , Sung Billy , Phau Ian
Published: August 2021

Purpose

The purpose of this study is to examine how perceived corporate social responsibility (CSR) motives may influence situational scepticism towards luxury brands and its effects on brand resonance, resilience to negative information and consumer advocacy of luxury brands. The moderating role of perceived fit towards luxury brand CSR initiatives is also investigated.

Design/methodology/approach

An experimental approach on a 2 × 2 matrix was used. Data are collected through a consumer panel.

Findings

Values-driven motives were found to lead to lower consumer situational scepticism and egoistic-driven motives would lead to higher levels of consumer situational scepticism. While higher consumer situational scepticism leads to lower brand resonance, there is no significant relationship between scepticism and resilience to negative information and consumer advocacy. The findings also suggest that perceived fit moderates the relationship between consumer situational scepticism to resilience to negative information and consumer situational scepticism to consumer advocacy.

Originality/value

The key originality of the study is that it provides empirical insights into situational scepticism of CSR initiatives and its influence in consumer and management outcomes in luxury brands.
Rethinking the trajectory of economic development: a study of firm entry mode under reverse directionality
Authors: Balachander Jayaram
Published: August 2021

Purpose

Most of the research studies on entry mode have been done through the lens of manufacturing firms from mature economic countries entering the Global South countries, and most of the related frameworks and theories have been developed to explain this perspective. This paper presents an understanding of entry mode strategies of services firms from the Global South countries entering into countries with mature economies by considering six software services firms in India entering the US market. The study develops a framework that incorporates multiple theories – both from an emerging economy perspective as well as a services perspective.

Design/methodology/approach

This study is exploratory in nature and focuses on the how and why aspects of strategic decisions. Qualitative research has traditionally been chosen when the main research objective is to improve understanding of a phenomenon. A multiple case study approach was used in this research. One of the key aspects of this study is the impact of different theories (institutional, network and other theories) on enterprises of different sizes. Therefore six cases – two each on small, medium and large enterprises – were selected.

Findings

Results identify addressable market size, cultural aspects, firm size, resource and service characteristics as dominating factors that influenced choice of entry modes. From a theoretical perspective, the author finds that theories such as transaction cost theory, eclectic paradigm and other popular theories associated with entry mode do not successfully explain the entry mode strategies for firms from the Global South. Strategic theory, such as resource-based view, motivation of a firm, have some application but do not explain, in isolation, all aspects of the entry mode choices.

Research limitations/implications

The study is an exploratory study and needs more data to validate the themes expressed in its conclusions. The study also focused on one industry and one country. Different industries within the same country may have different characteristics and may not follow the observations found in this study. Similarly, firms from other countries with similar economic characteristics may exhibit very different behavior. As a result, the themes that were expressed for software companies in India may not be generalizable across other industries and countries.

Originality/value

This study is significant for both academics and managers. For academics, the study addresses a significant gap in the literature. For managers, this study provides a framework for managers to evaluate and select the entry mode strategy that would be most effective in a successful expansion into foreign countries.

CSR portfolio characteristics and performance outcomes: examining the impacts of CSR portfolio diversity and dynamism
Authors: Turner Kyle , Turner Craig A. , Heise William H.
Published: August 2021

Purpose

The purpose of this paper is to introduce and test a portfolio view of a firm’s corporate social responsibility (CSR) activities. Drawing from stakeholder theory and the dynamic capabilities literature, the authors introduce CSR portfolio diversity and dynamism as key portfolio characteristics that have differential impacts across short- and long-term performance contexts.

Design/methodology/approach

The study draws from the Kinder, Lydenberg and Domini database to examine CSR portfolio diversity and dynamism across seven dimensions of CSR activities. The authors test the direct and indirect relationships between CSR portfolio characteristics and both short- and long-term performance outcomes to assess the opportunities and challenges associated with managing a diverse and dynamic CSR portfolio.

Findings

The findings suggest that a diverse portfolio of CSR activities positively impacts long-term performance; however, CSR portfolio diversity yields negative performance outcomes in the short-term. The authors also find that CSR portfolio dynamism moderates the relationship between CSR level and firm performance, such that a dynamic portfolio of CSR positively moderates the relationship between a firm’s CSR level and long-term performance; however, it negatively moderates the relationship between CSR level and short-term performance.

Originality/value

This study integrates insights from the literature that examine the independent effects of individual CSR activities and the broader perspective that assesses the aggregated summation of CSR activities in relation to firm performance. By taking a portfolio perspective, the present study provides a unique integration of these two research streams to examine the performance implications of engaging in a diverse and dynamic range of CSR activities.
Thanatopsis and mortality mediation within “lightest” dark tourism
Authors: Light Duncan , Ivanova Preslava
Published: August 2021

Purpose

This paper aims to investigate the visitor experience at a “lightest” dark tourism attraction, focusing on issues of thanatopsis and mortality mediation.

Design/methodology/approach

Data were collected through semi-structured interviews with 24 visitors to a “Dungeon”-style attraction in the UK (a site of “lightest” dark tourism). The interviews were analysed using thematic analysis; four themes were identified.

Findings

Reflection on, and contemplation of, issues of life and death was a common (but not universal) component of the visitor experience. Four forms of such reflection were apparent: considering absent/present death; thanatopsis (reflection on the self’s inevitable mortality); reflecting on the nature of death and dying in the past; and enjoyment of the opportunity to engage with death without fear in the safe setting of a visitor attraction. Some visitors also reflected on issues of individual and collective morality, in both past and present.

Research limitations/implications

“Lightest” dark tourism is not necessarily about shallow experiences. Instead, many visitors are active agents, engaged in acts of making meaning about issues of death and life. This calls for a more sophisticated conceptualisation of such visitors.

Originality/value

The mortality mediation model is widely accepted as a way of explaining the experience of visiting places of death but has rarely been subject to empirical scrutiny. This is one of few studies to explore in detail issues of mortality mediation and thanatopsis in the context of “lightest” dark tourism.
Physiology and genetics of ethanologenesis in the acetogenic bacterium Acetobacterium woodii
Authors: Moon Jimyung , Müller Volker
Published: August 2021

The acetogenic model bacterium Acetobacterium woodii is well‐known to produce acetate by homoacetogenesis from sugars, but under certain conditions minor amounts of ethanol are produced in addition. Here, we have aimed to identify physiological conditions that increase electron and carbon flow towards ethanol production. Ethanol was only produced from fructose but not from H2 + CO2, formate, pyruvate, lactate or alanine. In the absence of Na+, the Wood–Ljungdahl pathway (WLP) of acetate formation is not functional. Therefore, the ethanol yield increased to 0.42 mol/mol (ethanol/fructose) with an ethanol/acetate ratio of 0.28 mol/mol. The presence of bicarbonate/CO2 stimulated electron and carbon flow through the WLP and led to less ethanol produced. Of the 11 potential alcohol dehydrogenase genes, the most upregulated during ethanologenesis was adh4. A deletion of adh4 led to an increase in ethanol production by 100% to a yield of 0.79 mol/mol (ethanol/fructose); this correlated with an increase in transcript abundance of adh6. In sum, our studies revealed low Na+ and bicarbonate/CO2 as factors that trigger ethanol formation and that a deletion of adh4 drastically increased ethanol formation in A. woodii.
