Structures of Tweety Homolog Proteins TTYH2 and TTYH3 reveal a Ca2+-dependent switch from intra- to inter-membrane dimerization
Authors: Li Baobin , Hoel Christopher M. , Brohawn Stephen G.
Published: August 2021

Tweety homologs (TTYHs) comprise a conserved family of transmembrane proteins found in eukaryotes with three members (TTYH1-3) in vertebrates. They are widely expressed in mammals including at high levels in the nervous system and have been implicated in cancers and other diseases including epilepsy, chronic pain, and viral infections. TTYHs have been reported to form Ca2+- and cell volume-regulated anion channels structurally distinct from any characterized protein family with potential roles in cell adhesion, migration, and developmental signaling. To provide insight into TTYH family structure and function, we determined cryo-EM structures of Mus musculus TTYH2 and TTYH3 in lipid nanodiscs. TTYH2 and TTYH3 adopt a novel fold which includes an extended extracellular domain with a partially solvent exposed pocket that may be an interaction site for hydrophobic molecules. In the presence of Ca2+, TTYH2 and TTYH3 form homomeric cis-dimers bridged by extracellularly coordinated Ca2+. Strikingly, in the absence of Ca2+, TTYH2 forms trans-dimers that span opposing membranes across a ~130 Å intermembrane space as well as a monomeric state. All TTYH structures lack ion conducting pathways and we do not observe TTYH2-dependent channel activity in cells. We conclude TTYHs are not pore forming subunits of anion channels and their function may involve Ca2+-dependent changes in quaternary structure, interactions with hydrophobic molecules near the extracellular membrane surface, and/or association with additional protein partners.

Reproductive phenology is well known to be a key feature of crop adaptation to diverse ecogeographic variation and management practices. Lentil is one of the founder pulse crops of middle-eastern Neolithic agriculture, and the modern-day domesticated lentil germplasm is generally considered to form three broad adaptation groups: Mediterranean, South Asian and northern temperate, which correspond approximately to the major global production environments. Understanding the molecular basis of these adaptations is crucial to maximise efficiency of breeding programs. Here, we use a QTL approach to dissect the earliness that is characteristic of the South Asian pilosae ecotype, and that suits it to the typically short winter cropping season. We identified two loci, DTF6a and DTF6b, at which dominant alleles confer early flowering. We show that, although these loci can interact in an additive manner, DTF6a alone is sufficient to confer early flowering even in extremely short photoperiods. Comparisons with closely related legume species confirmed the presence of a conserved cluster of three FT orthologs among potential candidate genes in the region, and expression analysis in near-isogenic material showed that the early dtf6a allele is associated with a strong derepression of the FTa1 gene in particular. Analysis of sequence variation revealed the presence of a 7.4 kb deletion in the FTa1-FTa2 intergenic region in the pilosae parent, and a wide survey of over 400 accessions with diverse origin showed that the dtf6a allele is dominant in South Asia material. Collectively, these results contribute to understanding the molecular basis of global adaptation in lentil, and further emphasize the importance of this conserved genomic region for adaptation in temperate legumes generally.
Peptide Scanning of SARS-CoV and SARS-CoV-2 Spike Protein Subunit 1 Reveals Potential Additional Receptor Binding Sites
Authors: Lin Weilin , Rafeya Jannatul , Roschewitz Vanessa , Smith David , Keller Adrian , Zhang Yixin
Published: August 2021

The binding of SARS-CoV and SARS-CoV-2 to the ACE2 receptor on human cells is mediated by the spike protein subunit 1 (S1) on the virus surfaces, while the receptor binding domains (RBDs) of S1 are the major determinants for the interaction with ACE2 and dominant targets of neutralizing antibodies. However, at the virus-host interface, additional biomolecular interactions, although being relatively weak in affinity and low in specificity, could also contribute to viral attachment and play important roles in gain- or loss-of-function mutations. In this work, we performed a peptide scanning of the S1 domains of SARS-CoV and SARS-CoV-2 by synthesizing 972 16-mer native and mutated peptide fragments using a high throughput in situ array synthesis technology. By probing the array using fluorescently labelled ACE2, a number of previously unknown potential receptor binding sites of S1 have been revealed. 20 peptides were synthesized using solid phase peptide synthesis, in order to validate and quantify their binding to ACE2. Four ACE2-binding peptides were selected, to investigate whether they can be assembled through a biotinylated peptide/neutravidin system to achieve high affinity to ACE2. A number of constructs exhibited high affinity to ACE2 with Kd values of pM to low nM.

Published: August 2021

G-quadruplexes (G4s) are noncanonical DNA secondary structures formed through the self-association of guanines, and G4s are distributed widely across the genome. G4 participates in multiple biological processes including gene transcription, and G4-targeted ligands serve as potential therapeutic agents for DNA-targeted therapies. However, genome-wide studies of the exact roles of G4s in transcriptional regulation are still lacking. Here, we establish a sensitive G4-CUT&Tag method for genome-wide profiling of native G4s with high resolution and specificity. We find that native G4 signals are cell type–specific and are associated with transcriptional regulatory elements carrying active epigenetic modifications. Drug-induced promoter-proximal RNA polymerase II pausing promotes nearby G4 formation. In contrast, G4 stabilization by G4-targeted ligands globally reduces RNA polymerase II occupancy at gene promoters as well as nascent RNA synthesis. Moreover, ligand-induced G4 stabilization modulates chromatin states and impedes transcription initiation via inhibition of general transcription factors loading to promoters. Together, our study reveals a reciprocal genome-wide regulation between native G4 dynamics and gene transcription, which will deepen our understanding of G4 biology toward therapeutically targeting G4s in human diseases.
Entorhinal cortical Island cells regulate temporal association learning with long trace period
Authors: Yokose Jun , Marks William D. , Yamamoto Naoki , Ogawa Sachie K. , Kitamura Takashi
Published: August 2021

Temporal association learning (TAL) allows for the linkage of distinct, nonsynchronous events across a period of time. This function is driven by neural interactions in the entorhinal cortical–hippocampal network, especially the neural input from the pyramidal cells in layer III of medial entorhinal cortex (MECIII) to hippocampal CA1 is crucial for TAL. Successful TAL depends on the strength of event stimuli and the duration of the temporal gap between events. Whereas it has been demonstrated that the neural input from pyramidal cells in layer II of MEC, referred to as Island cells, to inhibitory neurons in dorsal hippocampal CA1 controls TAL when the strength of event stimuli is weak, it remains unknown whether Island cells regulate TAL with long trace periods as well. To understand the role of Island cells in regulating the duration of the learnable trace period in TAL, we used Pavlovian trace fear conditioning (TFC) with a 60-sec long trace period (long trace fear conditioning [L-TFC]) coupled with optogenetic and chemogenetic neural activity manipulations as well as cell type-specific neural ablation. We found that ablation of Island cells in MECII partially increases L-TFC performance. Chemogenetic manipulation of Island cells causes differential effectiveness in Island cell activity and leads to a circuit imbalance that disrupts L-TFC. However, optogenetic terminal inhibition of Island cell input to dorsal hippocampal CA1 during the temporal association period allows for long trace intervals to be learned in TFC. These results demonstrate that Island cells have a critical role in regulating the duration of time bridgeable between associated events in TAL.
Sleep spectral power correlates of prospective memory maintenance
Authors: Cunningham Tony J. , Bottary Ryan , Denis Dan , Payne Jessica D.
Published: August 2021

Prospective memory involves setting an intention to act that is maintained over time and executed when appropriate. Slow wave sleep (SWS) has been implicated in maintaining prospective memories, although which SWS oscillations most benefit this memory type remains unclear. Here, we investigated SWS spectral power correlates of prospective memory. Healthy young adult participants completed three ongoing tasks in the morning or evening. They were then given the prospective memory instruction to remember to press “Q” when viewing the words “horse” or “table” when repeating the ongoing task after a 12-h delay including overnight, polysomnographically recorded sleep or continued daytime wakefulness. Spectral power analysis was performed on recorded sleep EEG. Two additional groups were tested in the morning or evening only, serving as time-of-day controls. Participants who slept demonstrated superior prospective memory compared with those who remained awake, an effect not attributable to time-of-day of testing. Contrary to prior work, prospective memory was negatively associated with SWS. Furthermore, significant increases in spectral power in the delta-theta frequency range (1.56 Hz–6.84 Hz) during SWS was observed in participants who failed to execute the prospective memory instructions. Although sleep benefits prospective memory maintenance, this benefit may be compromised if SWS is enriched with delta–theta activity.
Fuzzy robust fault estimation scheme for fault tolerant flight control systems based on unknown input observer
Authors: Unal Gulay
Published: August 2021

Purpose

The purpose of this study is to present a new integrated structure for a fault tolerant aircraft control system because fault diagnosis of flight control systems is extremely important in obtaining healthy flight. An approach to detect and isolate aircraft sensor faults is proposed, and a new integrated structure for a fault tolerant aircraft control system is presented.

Design/methodology/approach

As disturbance and sensor faults are mixed together in a flight control system, it is difficult to isolate any fault from the disturbance. This paper proposes a robust unknown input observer for state estimation and fault detection as well as isolation using fuzzy logic.

Findings

The dedicated observer scheme (DOS) and generalized observer scheme (GOS) are used for fault detection and isolation in an observer-based approach. Using the DOS, it has been shown through simulation that sensor fault detection and isolation can be made, but here the threshold value must be well chosen; if not, the faulty sensor cannot be correctly isolated. On the other hand, the GOS is more usable and flexible than the DOS and allows isolation of faults more correctly and for a fuzzy logic-based controller to be used to realize fault isolation completely.

Originality/value

The fuzzy logic approach applied to the flight control system adds an important key for sensor fault isolation because it reduces the effect of false alarms and allows the identification of different kinds of sensor faults. The proposed approach can be used for similar systems.
Holistic framework for evaluating and improving information security culture
Authors: Arbanas Krunoslav , Spremic Mario , Zajdela Hrustek Nikolina
Published: August 2021

Purpose

The objective of this research was to propose and validate a holistic framework for information security culture evaluation, built around a novel approach, which includes technological, organizational and social issues. The framework's validity and reliability were determined with the help of experts in the information security field and by using multivariate statistical methods.

Design/methodology/approach

The conceptual framework was constructed upon a detailed literature review and validated using a range of methods: first, measuring instrument was developed, and then content and construct validity of measuring instrument was confirmed via experts' opinion and by closed map sorting method. Convergent validity was confirmed by factor analysis, while the reliability of the measuring instrument was tested using Cronbach's alpha coefficient to measure internal consistency.

Findings

The proposed framework was validated based upon the results of empirical research and the usage of multivariate analysis. The resulting framework ultimately consists of 46 items (manifest variables), describing eight factors (first level latent variables), grouped into three categories (second level latent variables). These three categories were built around technological, organizational and social issues.

Originality/value

This paper contributes to the body of knowledge in information security culture by developing and validating holistic framework for information security culture evaluation, which does not observe information security culture in only one aspect but takes into account its organizational, sociological and technical component.

Published: August 2021

Purpose

This study aims to investigate the underlying factors that give rise to the set of sustainability indicators which are used for the implementation of sustainable construction projects and eventually the production of sustainable built assets.

Design/methodology/approach

To accomplish the purpose of this research, an online questionnaire survey was administered to a sample of 200 experts. By employing the statistical method of exploratory factor analysis (EFA), five distinct dimensions (factors) of stakeholders' attitudes were revealed.

Findings

The findings indicate that the sustainability indicators are based on five underlying factors, namely (1) sustainable competitiveness; (2) stakeholder engagement; (3) sustainable economic growth; (4) social sustainability; and (5) resource conservation and environmental policy.

Research limitations/implications

More studies would be welcome to verify the underlying factors revealed in this paper.

Practical implications

The knowledge of the underlying factors enables senior management to maintain a balance of choices during the project management (PM) phase in order to implement and deliver sustainable construction projects. Furthermore, the findings deepen the understanding toward sustainable PM practices by providing insights on its core attributes.

Originality/value

As a theoretical contribution to knowledge, this study enhances the body of knowledge by revealing the underlying factors that give rise to the predefined set of the 82 sustainability indicators which are used to enable sustainable construction projects. In practice, the findings aid senior management in adopting strategies that enhance the delivery of sustainable construction projects.
Why trainees evaluate the same trainer differently? Examining a dual-process model of training effectiveness
Authors: Baig Muhammad Usman Anwar , Naqvi Sayyed Muhammad Mehdi Raza
Published: August 2021

Purpose

It is commonly observed in trainings that all trainees do not get satisfied with the performance of the trainer. The usual way to increase the satisfaction of trainees is a stress on improving task communication of the trainer. It is based on the assumption that effective task communication essentially fosters training effectiveness. This study aims to provide preliminary evidence that effective task communication can also obstruct training effectiveness besides promoting it. To achieve this objective, the authors hypothesized a dual-process model of training effectiveness based on uncertainty reduction theory.

Design/methodology/approach

This was a field study in which the authors collected time-lagged data from seven trainings. The trainings were designed to impart technical knowledge of multilevel analyses to professional social science researchers. Confirmatory factor analysis for ordinal indicators was used to test the measurement properties of the model and scales. Structural equation modeling for ordinal indicators was used to test hypotheses.

Findings

This study provided evidence of an overall positive effect of the trainer’s task communication on the trainee’s communication satisfaction. A complex mediation analysis also revealed the existence of two opposite psychological processes. While the first process transmitted the positive effect of task communication to communication satisfaction, the other process diminished this positive effect. Implications for the theory and practice of training are discussed.

Originality/value

Training scholars and practitioners universally believe that an effective task communication of trainers essentially promotes training effectiveness. This study has provided empirical evidence that this assumption is an incomplete picture of a complex reality that requires further investigation.
The essential skills and competencies of LIS professionals in the digital age: alumni perspectives survey
Authors: Yadav Akhilesh K.S.
Published: August 2021

Purpose

The librarianship profession has gone through many changes over time, more so with the emergence of digital technologies. To thrive in the library and information science (LIS) profession, professionals must have knowledge, skills, competencies and abilities to perform their job duties. The purpose of this paper was to identify essential knowledge, skills and abilities (KSAs) for the LIS professionals.

Design/methodology/approach

The targeted survey group for the study were alumni of ten LIS schools in India, who are now working in various library sectors. A structured questionnaire was designed to seek their opinions, and the snowball sampling technique was adopted to collect the data. A total of 377 responses were received from the respondents.

Findings

Five broad areas of KSAs were identified: traditional library skills, research skills, computing skills, data management skills and soft skills. This study found that computing skills, library automation and library digitization are considered absolutely essential for the LIS professionals. The results also brought out the importance of “soft skills” for the LIS professionals. Prerequisite knowledge of library liaison services, technical services and foreign language were reportedly important only for working in special libraries.

Practical implications

This study identified 54 skills across five broad areas that are essential for the professionals working in library and information centres. The research findings will be helpful for the educators who want to design, develop and upgrade the LIS course curriculum in accordance with the skills that are in demand in the market.

Originality/value

This study establishes that though the participants expressed satisfaction with the practicum of the curriculum, the LIS course curriculum needs to be improved. It would be in the best interest of the LIS schools to identify and rectify the gap.

Authors: Malanga Donald Flywell , Banda Memory John
Published: August 2021

Purpose

This study aims to assess the impact of mobile phones on the livelihoods of women microenterprises in two selected districts of Malawi.

Design/methodology/approach

This study adopted an interpretive qualitative approach. The authors conducted six focus group discussions with 33 women microenterprise owners in two selected districts of Malawi. This study was guided by the sustainable livelihood approach as an analytical framework.

Findings

The findings confirmed that to some extent use of mobile phones by women microenterprises helped them realise their livelihood outcomes. These included improved access to information, improved communication, improved marketing, reduced transport costs and improved efficiency and productivity. However, optimum benefits were highly curtailed by a number of factors such as poor information and communication technologies (ICT) infrastructure, security issues, high cost of talk time and data bundle, lack of ICT literacy, low education and sociocultural factors.

Originality/value

The findings provide evidence on the role of mobile phone technology play in promoting the value for women participating in business activities in disadvantaged communities. Policymakers and other stakeholders can use the findings as a basis for prioritising the improvement of mobile technology infrastructure in rural communities tailor-made to women microenterprises.

Authors: Loan Fayaz Ahmad , Bisma Bashir , Nahida Nasreen
Published: August 2021

Purpose

The purpose of the study is to conduct a scientometric analysis of cybersecurity literature indexed in the core collection of the Web of Science for a period of ten years (2011–2020).

Design/methodology/approach

Cybersecurity is a focused topic of research across the globe. To identify the global research productivity in the field, the terms “cybersecurity, cyber-security, web security, information security, computer security, etc.” were used for retrieving the publications in the advanced search mode of the database “Web of Science”, limiting the time frame for 2011– 2020. The results retrieved were downloaded in the Excel file for further analysis and interpretation. The harvested data was analysed by using scientometric techniques to measure the progress such as growth rate, doubling time and author collaborations. Besides, the Biblioshiny and VOSviewer software were used for mapping networks.

Findings

The research output in the field of cybersecurity has shown an increasing trend during 2011–2020, and the maximum number of scholarly publications was published in 2020 (1,581), i.e. more than 715% of 2011 (221). A good number of countries (93) have contributed globally in cybersecurity research, and the highest share in research publications was reported by the USA (23.55%), followed by China (23.24%), South Korea (5.31%), UK (5.28%) and India (4.25%). The authorship patterns in cybersecurity publications show a collaborative trend, as most articles have been published by multiple authors. Total 5,532 (90.14%) articles have been published in co-authorship, whereas only 605 (9.86%) articles have been published by single authors. Keyword analysis shows that the most common keyword research by the authors is cybersecurity and its variants such as “cyber security” and “cyber-security” (1,698) followed by security (782), computer security (680) and information security (329).

Research limitations/implications

The database studied for the work does not represent the total literary output available on the theme. There are plenty of other databases, such as Scopus, Compendex, INSPEC, IEEE Xplore, arXiv, contributing to the same theme as well.

Practical implications

The findings of the study may help researchers, information technologists, library professionals and information specialists to identify the research progress, authorship patterns, collaborative networks and hot topics of research in the field of cybersecurity. Besides, it will assess the global response to the cybersecurity issue.

Originality/value

The study is the scientometric analysis of the cybersecurity based on current literature and will highlight the progress and development of global research in the said field.
Gender-based variations in the perception of climate change impact, vulnerability and adaptation strategies in the Pra River Basin of Ghana
Authors: Bessah Enoch , Raji AbdulGaniy Olayinka , Taiwo Olalekan John , Agodzo Sampson Kwaku , Ololade Olusola Oluwayemisi , Strapasson Alexandre , Donkor Emmanuel
Published: August 2021

Purpose

This study aims to assess gender-based differences on farmers’ perception of impacts and vulnerability to climate change and the implementation of adaptation strategies in the Pra River Basin of Ghana, while also providing lessons for other Sub-Saharan nations and regions with similar conditions.

Design/methodology/approach

The study used semi-structured interviews and questionnaires to collect data from 344 farmers, 64 participants in focus group discussions and 6 agriculture extension officers (key informants) from 10 districts in the Pra River Basin of Ghana.

Findings

Results showed several differences in how climate change is perceived and tackled by male and female genders. In the perception of male farmers, for example, they were found to be more vulnerable to increased temperature, and changes in rainfall and growing season, whereas female farmers on average were considered to be less resilient to floods and droughts for different reasons. Moreover, floods posed higher risks to farming than other climate change impacts. Gender roles had a significant correlation with the type of adaptation strategies practised. Men adopted agrochemicals more often than women, as an adaptation strategy.

Research limitations/implications

Gender-differentiated interventions should be incorporated in the national climate change action plan for sustainable development in a rain-fed agricultural economy such as Ghana. The study recommends several actions to promote gender equity in the assessed region.

Originality/value

This research assessed the gender differentials in climate trends, impact, vulnerability and adaptation based on primary data collected between April and May 2019 and compared the results with climate data in the basin for the period 1991–2014. It is an empirical study focused on primary data analysis obtained in loco by authors, involving approximately 400 participants.
Skills and competencies for digital transformation – a critical analysis in the context of robotic process automation
Authors: Schlegel Dennis , Kraus Patrick
Published: August 2021

Purpose

Digital transformation of organizations has major implications for required skills and competencies of the workforce, both as a prerequisite for implementation, and, as a consequence of the transformation. The purpose of this study is to analyze required skills and competencies for digital transformation using the context of robotic process automation (RPA) as an example.

Design/methodology/approach

This study is based on an explorative, thematic coding analysis of 119 job advertisements related to RPA. The data was collected from major online job platforms, qualitatively coded and subsequently analyzed quantitatively.

Findings

The research highlights the general importance of specific skills and competencies for digital transformation and shows a gap between available skills and required skills. Moreover, it is concluded that reskilling the existing workforce might be difficult. Many emerging positions can be found in the consulting sector, which raises questions about the permanent vs temporary nature of the requirements, as well as the difficulty of acquiring the required knowledge.

Originality/value

This paper contributes to knowledge by providing new empirical findings and a novel perspective to the ongoing discussion of digital skills, employment effects and reskilling demands of the existing workforce owing to recent technological developments and automation in the overall context of digital transformation.
Classification of halal hotels based on industrial perceived value: a study of Indonesia and Thailand
Authors: Rachmiatie Atie , Rahmafitria Fitri , Suryadi Karim , Larasati Ajeng Ramadhita
Published: August 2021

Purpose

The research aims to classify halal hotels based on Islamic values as embodied in both physical and non-physical attributes.

Design/methodology/approach

This study explores the perceived values of business owners of the halal hotels.

Findings

Perceptions of hotel owners are divided into three types: those who view the value of halal hotel only in terms of branding and attracting consumers; those who consider the ideology behind halal hotels based on strong Islamic values; and those who avoid halal branding but implement Islamic values in their hotels. For the hotel industry, halal certification is not a priority because a minimum effort at implementing halal standards can already attract Muslim customers. This case is especially true for countries where Muslims make up the majority of the population.

Research limitations/implications

This study was limited to a case study in Bandung and Bangkok as a representative of halal tourism in Asia. Hence, it could be extended by conducting comparative studies with other cities in Association of South East Asian Nation which already declare to develop halal tourism.

Practical implications

The findings of this research show that there is a large variety of halal hotel products, depending on the Islamic values upheld, which is causing difficulties for the government in creating standards. Then the result can help inform the government in establishing the strategic framework of halal tourism development, more particularly in the formulation of policy for industrial actors.

Originality/value

The findings contribute to the concept of product-centered business, in which it is generally assumed that industrial actors are frequently focused on the mere label of “halal” and ignore the true values. However, the research shows that some industrial actors put Islamic values first instead of the mere halal label, and another case shows that some of them implement Islamic values in their business but avoid halal branding. This empirical evidence shows that in halal hotels, the concept of product-centered is not always proper. The quality of halal hotel products depends on the Islamic value of the owner, not always influenced by business imperatives.
Identifying wine consumers interested in environmentally sustainable production practices
Authors: Kelley Kathleen , Todd Marielle , Hopfer Helene , Centinari Michela
Published: August 2021

Purpose

This study aims to characterize several wine consumer segments who were “likely” to sample (i.e. taste before purchasing) wine from vineyards using cover crops, a sustainable production practice that reduces herbicide applications, and identify those with a greater probability of being a viable target market based on survey responses.

Design/methodology/approach

A total of 956 wine consumers from the Mid-Atlantic and boarding US states were separated into segments based on an ECHAID (exhaustive Chi-square automatic interaction detector) classification tree from internet survey responses.

Findings

Out of the 12 created segments, 6 (n = 530, 72% of training data) contained participants who were at least 1.02 times (index score =102%) more “likely” to try the wine compared to the overall sample and were willing to pay $18.99 for a 750-mL bottle of the wine, which included a $1 surcharge to cover associated production costs. Of these, three (n = 195, 26%) had the greatest potential for which a marketing plan could be developed (index scores of 109%–121%), with over half in each segment willing to pay $20.99 for the bottle of wine, which could motivate growers to consider implementing this sustainable strategy.

Originality/value

Although several segments of participants were “likely” to sample the sustainably produced wine, an ECHAID classification tree allowed us to identify participants who would not pay $18.99 for a 750-mL bottle of wine, even after learning about the use of cover crops and the trade-off ($1 bottle surcharge). By narrowing the number of potential “likely” segments to those with a greater potential of sampling the wine, more purposeful marketing strategies can be developed based on demographics, attitudes, and behaviors defined in the model.
The COVID-19 pandemic, customer satisfaction and sales performance in wine tasting rooms in the Finger Lakes region of New York State
Authors: Davis Trent James , Gomez Miguel I.
Published: August 2021

Purpose

The purpose of this paper is to identify the drivers of customer satisfaction (CS) and sales performance at wineries in the Finger Lakes region of New York State in the context of changes winery tasting rooms implemented due to the COVID-19 pandemic.

Design/methodology/approach

A survey was administered to tasting room visitors at two wineries in October 2020 in the Finger Lakes region of New York State resulting in 215 usable survey responses measuring customer satisfaction. A factor analysis was used to identify primary factors influencing overall CS. The authors then modeled how these primary factors, along with various demographic factors, influence sales metrics. The results are then compared with previous estimates of such drivers in pre-COVID tasting rooms.

Findings

The authors identified four main CS factors: Staff Interactions, Wine Tasting, COVID-19 Precautions and Ambience that play a significant role in overall CS. Of these, Wine Tasting was shown to have a positive influence on total amount spent and the number of bottles purchased, whereas COVID-19 Precautions positively impacted the number of bottles purchased. Overall, CS is also shown to positively impact total amount spent and number of bottles purchased. Customers are shown to prefer some changes to the tasting room due to COVID-19, such as having table service and reservations.

Originality/value

This is the first study researching the influence of certain tasting room changes implemented due to the COVID-19 pandemic has had on CS and wine-purchasing decisions in tasting rooms.
Remittances-inflation nexus in South Asia: an empirical examination
Authors: Basnet Hem C. , Donou-Adonsou Ficawoyi , Upadhyaya Kamal
Published: August 2021

Purpose

The purpose of this paper is to examine whether remittances induce inflation in South Asian countries, namely, Bangladesh, India, Nepal, Pakistan and Sri Lanka.

Design/methodology/approach

This study uses panel cointegration and Pooled Mean Group techniques covering from 1975 to 2017 to estimate the long-run and the short-run effect of remittances on inflation.

Findings

The estimated results suggest that the inflationary impact of remittances in South Asia depends on the time length. The inflow tends to lower inflation in the short run, whereas it increases in the long run. The findings highlight the regional peculiarity in the impact of remittances on the price level. The results are statistically significant and are confirmed by the Mean Group estimation as well.

Originality/value

Most past studies investigating the nexus between remittances and inflation in the South Asian context examine either these countries individually or include them all in a pool of big cross-sections. This study contributes to the literature by addressing this void. The South Asian countries should not generalize the earlier findings on the link between remittance inflows and inflation, as the short-run effect is different from the long run. Thus, these countries would be better off designing long-run policies that are different from the short run.
Organisational form and performance in fashion retailing
Authors: Mejía-Vásquez Pericles Ramón , Sánchez-Gómez Roberto , Serafim da Silva Sheila , Vázquez-Suárez Luis
Published: August 2021

Purpose

This research seeks to discover how the organisational form (franchising vs vertical integration) of 384 fashion stores belonging to a Spanish franchise chain influences unit-level performance measured through three key indicators commonly used in the retail literature: sales per square metre, sales per employee and service quality scores.

Design/methodology/approach

The authors have analysed this research question using bivariate and multivariate analyses, with a panel dataset that includes quarterly establishment-level data covering the period from January 2018 to December 2019.

Findings

The aggregated data initially reveal weaker outcomes among franchised establishments. However, after controlling for other variables related to the fashion stores and their local markets, the authors have found that franchised establishments record higher sales both per square metre and per employee than vertically integrated stores. The findings also reveal that franchised establishments record lower service quality scores than their company-owned counterparts.

Originality/value

Nothing has been published on the differences between franchising and company ownership in terms of establishment-level performance in fashion retailing.
Coordination at the 10-year mark of the JHLSCM–from global response to local preparedness
Authors: Jahre Marianne , Jensen Leif-Magnus
Published: August 2021

Purpose

At the inception of the Journal of Humanitarian Logistics and Supply Chain Management (JHLSCM), logistics coordination was identified as important, both in practice and research, but few studies on the topic had been published. Ten years later, many, if not most, papers in the journal mention the topic. So the picture has changed, but to what extent? This paper discusses how coordination research has followed humanitarian logistics practice and vice versa.

Design/methodology/approach

The point of departure in the present article is the most salient topic from the study’s original papers (Jahre et al., 2009; Jahre and Jensen, 2010). The authors discuss how these topics have developed in research and practice. A recent literature review (Grange et al., 2020) enables us to pick relevant papers from JHLSCM and supplement them with more recent ones. The authors complement this approach with updated data on the cluster system, particularly the logistics cluster, to add insights from the empirical domain.

Findings

In practice, the cluster concept has developed from coordination within clusters in response to the inclusion of inter-cluster coordination in preparedness, and more recently a focus on localized preparedness. However, JHLSCM research does not appear to have kept pace, with a few notable exceptions. The majority of its papers still focus on response. To the extent that preparedness is covered, it is primarily done so at the global level.

Originality/value

The authors use a framework to discuss humanitarian logistics coordination research and identify important gaps. Based on developments in practice, the study’s key contribution is a revised model with suggestions for further research.

The purpose of this paper is to defend the notion of “trust in technology” against the philosophical view that this concept is misled and unsuitable for ethical evaluation. In contrast, it is shown that “trustworthy technology” addresses a critical societal need in the digital age as it is inclusive of IT-security risks not only from a technical but also from a public layperson perspective.

Design/methodology/approach

From an interdisciplinary perspective between philosophy andIT-security, the authors discuss a potential instantiation of a “trustworthy information and communication technology (ICT)”: a solution for privacy respecting video surveillance. Here, strong data protection measures address grave concerns such as the threat of bulk biometric tracking of citizens. In a logical argument, however, the authors show that this technical notion of “trust” needs to be complemented by interlocking trust relations to justify public trust.

Findings

Based on this argument, the authors demonstrate that the philosophical position considering “trust in technology” to denote either “reliability” or “interpersonal trust” is too limited as it fails to address critical aspects of IT-security. In a broader, socio-technical sense, however, it is shown that several distinct accounts of trust – technical, interpersonal and institutional – should meaningfully interlock, to address concerns with ICTs.

Originality/value

This conceptual study demonstrates the potential of “trust in technology” for a more comprehensive evaluation of ICTs within the context of operation. Furthermore, it adds to the discussion of trust in IT-security by highlighting the layperson’s challenge of judging a technology’s trustworthiness. Vice versa, it contributes to Ethics of Technology by highlighting crucial IT-security needs.
Analysing the factors influencing customer engagement and value co-creation during COVID-19 pandemic: the case of online modest fashion SMEs in Egypt
Authors: AbdelAziz Kesmat , Md Saad Nor Hasliza , Thurasamy Ramayah
Published: August 2021

Purpose

The purpose of this paper is to analyse the factors which influence value co-creation intention through customer engagement during the COVID-19 pandemic. This paper studies the online modest fashion small- and medium-sized enterprises (SMEs) in Egypt as a Muslim country.

Design/methodology/approach

This paper is based on the social cognitive theory (SCT) and the literature to develop a theoretical framework of the factors influencing customers’ value co-creation intention on social media. The framework is then tested quantitatively through structural equation modelling based on partial least squares method (SEM-PLS) approach using the SmartPLS software.

Findings

The empirical analysis supported the SCT through the following conclusions: first, regarding the subject factors, self-efficacy has a positive significant effect on all dimensions of customer engagement and outcome expectation has a positive significant effect on cognitive customer engagement. Concerning the environmental factors, community experience has a positive significant effect on affective and behavioural customer engagement, whereas content quality has a positive significant effect on affective customer engagement. Second, customer engagement is a significant mediator through the dimensions of affective and behavioural customer engagement.

Practical implications

The findings of this study can help online modest fashion SMEs better comprehend the factors which influence the customers’ engagement for value co-creation intention whether it is subject factors or environmental factors. Therefore, they can better operate online and encourage customers to contribute to the development of new products and services and hence achieve a competitive advantage and survive in times of COVID-19.

Originality/value

Most of the existing studies focused on the value co-creation behaviour and output. However, there is limited research focusing on what contributes to the customers’ engagement for value co-creation intention, especially for online modest fashion and Muslim countries. Therefore, this study attempts to examine and bridge this research gap.
Assessing the sustainability of using drone technology for last-mile delivery in a blood supply chain

Published: August 2021

Purpose

Delivery management of perishable products such as blood in a supply chain is a considerable issue such that the last-mile delivery, which refers to deliver goods to the end user as fast as possible takes into account as one of the most important, expensive and, polluting segments in the entire supply chain. Regardless of economic challenges, the last-mile delivery faces social and environmental barriers to continuing operations while complying with environmental and social standards, therefore incorporating sustainability into last-mile logistic strategy is no longer an option but rather a necessity. Accordingly, the purpose of this paper is to consider a last-mile delivery in a blood supply chain in terms of using appropriate technologies such as drones to assess sustainability.

Design/methodology/approach

The authors discuss the impact of drone technology on last-mile delivery and its importance in achieving sustainability. They focus on the effect of using drones on CO2 emission, costs and social benefits by proposing a multi-objective mathematical model to assess sustainability in the last-mile delivery. A preemptive fuzzy goal programming approach to solve the model and measure the achievement degree of sustainability is conducted by using a numerical example to show the capability and usefulness of the suggested model, solution approach and, impact of drone technology in achieving all three aspects of sustainability.

Findings

The findings illustrate the achievement degree of sustainability in the delivery of blood based on locating distribution centers and allocating drones. Moreover, a comparison between drones and conventional vehicles is carried out to show the preference of using drones in reaching sustainability. A sensitivity analysis on aspects of sustainability and specifications of drone technology is conducted for validating the obtained results and distinguishing the most dominant aspect and parameters in enhancing the achievement degree of sustainability.

Originality/value

To the best of the authors’ knowledge, no research has considered the assessment of sustainability in the last-mile delivery of blood supply chain with a focus on drone technology.
Modeling and scheduling hybrid open shops for makespan minimization
Authors: Araújo Kennedy Anderson Guimarães de , Oliveira e Bonates Tiberius , Prata Bruno de Athayde
Published: August 2021

Purpose

This study aims to address the hybrid open shop problem (HOSP) with respect to the minimization of the overall finishing time or makespan. In the HOSP, we have to process n jobs in stages without preemption. Each job must be processed once in every stage, there is a set of mk identical machines in stage k and the production flow is immaterial.

Design/methodology/approach

Computational experiments carried out on a set of randomly generated instances showed that the minimal idleness heuristic (MIH) priority rule outperforms the longest processing time (LPT) rule proposed in the literature and the other proposed constructive methods on most instances.

Findings

The proposed mathematical model outperformed the existing model in the literature with respect to computing time, for small-sized instances, and solution quality within a time limit, for medium- and large-sized instances. The authors’ hybrid iterated local search (ILS) improved the solutions of the MIH rule, drastically outperforming the models on large-sized instances with respect to solution quality.

Originality/value

The authors formalize the HOSP, as well as argue its NP-hardness, and propose a mixed integer linear programming model to solve it. The authors propose several priority rules – constructive heuristics based on priority measures – for finding feasible solutions for the problem, consisting of adaptations of classical priority rules for scheduling problems. The authors also propose a hybrid ILS for improving the priority rules solutions.
