Published: March 2022

AbstractHere, we report the discovery of a ParM protein fromClostridium botulinum(CBgs-ParM), which forms a double-stranded polar filament. CBgs-ParM shares many similarities in its basic filament architecture with actin, however, Pi release after nucleotide hydrolysis induces a large lateral strand shift of ~2.5 nm. We identified the ParR (CBgs-ParR) that acts as a nucleation factor in the initial stage of polymerization, similar to ParR fromEscherichia coliplasmid R1. CBgs-ParR also functions as a depolymerization factor, probably by recognizing the structural change in the CBgs-ParM filament after Pi release. Comparison with CBH-ParM, another ParM fromClostridum botulinum, showed that subunit-subunit interacting regions largely differ, preventing co-polymerization, implying a selection pressure in evolution to prevent interference between different ParMRC systems.

Authors: Hsu Fu Chieh , Park Sung Hee , Miller Joseph C. 
Published: March 2022

PurposeThe primary purpose of this research is to segment food festivalgoers based upon their experiential value. Once those segments are found, it aims to examine whether the segments differ with regard to their perceived level of satisfaction, delight and loyalty.Design/methodology/approachA self-administered questionnaire was designed to assess the on-site festival experiential value, satisfaction, delight and loyalty of local and overseas visitors at the Macau International food festival. Data were analyzed by using the factor and cluster approach. To profile segments, a series of chi-square tests, ANOVAs and multivariate analysis of variance were performed.FindingsThis study uncovered three underlying dimensions of experiential value and classified four segments based on their experiential value among the food festivalgoers, which provides insightful implications for festival organizers and marketers. The segments differed in age, education level and place of residence. Furthermore, the multi-experiential value group was the most important segment, showing the highest festival satisfaction, delight and loyalty.Originality/valueExperiential value reflects a core value of festival attendees, where the experience is a determining factor in the creation of a successful festival and desirable outcomes. Limited studies, however, have been conducted to segment food festival markets according to their festival experience. This study identified experiential value, applying it as a segmentation criterion within a food festival setting.

Authors: Oladinrin Olugbenga Timo , Arif Mohamed , Rana Muhammad Qasim , Gyoh Louis 
Published: March 2022

Purpose
Many companies invest in innovations because of the inherent benefits, and research on innovation has increased over the year. However, the vast majority of research papers deals with purely technical matters. There seem to be growing concerns over ethical issues in adopting innovations in the construction industry. This extant review of literature aims to analyse the interrelations between the concepts of ethics and innovations in construction research to understand the advances of current scientific production and future lines of research.

Design/methodology/approach
Thus, this work presents a bibliometric analysis covering articles obtained from the Web of Science Core Collection Database published between 1995 and May 2021. A sample size of 5,786 research papers relevant to the study was evaluated using VOSviewer software.

Findings
The results of the analysis shed light on the evolution of the connection between the two concepts. The study highlighted Heng Li as the most productive author. The country with the most publications and citations is China. The most productive institution is the Hong Kong Polytechnic University. The results revealed a limited intellectual exchange and lack of cohesion characterising the two concepts (ethics and innovation), resulting in a situation whereby innovation-related researchers tend to follow personal trajectories in isolation from ethics-related researchers in the construction field.

Originality/value
This is probably the most comprehensive scientometric analysis ever conducted to examine the theoretical relationship between ethics and innovation in construction. This study adds to the so far limited knowledge in the field and provides insights for future research. Overall, this review may spur future research on dyad investigation of ethics and innovative related themes in construction such as ethics and sustainability, ethics and sensor-based technology and ethics and innovative safety approach.
Exploring the influencing factors of environmental deterioration: evidence from China employing ARDL–VECM method with structural breaks
Authors: Wang Hongwei 
Published: March 2022

Purpose
The environmental deterioration has become one of the most economically consequential and charged topics. Numerous scholars have examined the driving factors failing to consider the structural breaks. This study aims to explore sustainability using the per capita ecological footprints (EF) as an indicator of environmental adversities and controlling the resources rent [(natural resources (NR)], labor capital (LC), urbanization (UR) and per capita economic growth [gross domestic product (GDP)] of China.

Design/methodology/approach
Through the analysis of the long- and short-run effects with an autoregressive distributed lag model (ARDL), structural break based on BP test and Granger causality test based on vector error correction model (VECM), empirical evidence is provided for the policies formulation of sustainable development.

Findings
The long-run equilibrium between the EF and GDP, NR, UR and LC is proved. In the long run, an environmental Kuznets curve (EKC) relationship existed, but China is still in the rising stage of the curve; there is a positive relationship between the EF and NR, indicating a resource curse; the UR is also unsustainable. The LC is the most favorable factor for sustainable development. In the short term, only the lagged GDP has an inhibitory effect on the EF. Besides, all explanatory variables are Granger causes of the EF.

Originality/value
A novel attempt is made to examine the long-term equilibrium and short-term dynamics under the prerequisites that the structural break points with its time and frequencies were examined by BP test and ARDL and VECM framework and the validity of the EKC hypothesis is tested.
The role of the hub-firm in developing innovation capabilities: considering the French wine industry cluster from a resource orchestration lens
Authors: Kumar Maneesh , Pullman Madeleine , Bouzdine-Chameeva Tatiana , Sanchez Rodrigues Vasco 
Published: March 2022

PurposeThis paper explores how hub-firms in a regional industrial cluster orchestrate resources to enhance the innovation capabilities of member firms and how this role changes as innovation projects develop. The work advances our understanding of how innovation-oriented clusters can drive the collaboration process, support the development of member capabilities and achieve desired outcomes.Design/methodology/approachThe research utilises exploratory case studies within an innovation cluster, where a hub-firm brings together different players for specific innovation projects. Using resource orchestration theory, the paper analyses six project cases to reveal the shifting roles and activities related to structuring, bundling and leveraging different resources for innovation capabilities particularly associated with improved quality and reputation for the firms and region.FindingsThe study reveals the important role played by the cluster hub-firm in structuring, bundling and leveraging resources to create and fund project teams. After project formation, a team member takes the role of an orchestrator to bundle further and then leverage the resources to achieve desired outcomes for the team and the region.Research limitations/implicationsThis work focuses on a wine industry but has implications for the success orchestration of other regional industrial clusters. Also, the lack of hub-firm interaction during the project process provides an opportunity to consider mechanisms for better guidance of the project team.Practical implicationsThere are implications for practitioners for participating in and further improving the collaborative innovative process.Social implicationsPolicymakers can benefit from the study as the required practices for stimulating innovation capabilities and economic development in a region are discussed.Originality/valueThis research enhances understanding of the hub-firm's role in a regional cluster not only in orchestrating resources to create collaborative innovation projects but how the role shifts over time.
Prediction of cold chain logistics temperature using a novel hybrid model based on the mayfly algorithm and extreme learning machine
Authors: Lim Ming K. , Li Yan , Wang Chao , Tseng Ming-Lang 
Published: March 2022

PurposeThe transportation of fresh food requires cold chain logistics to maintain a low-temperature environment, which can reduce food waste and ensure product safety. Therefore, temperature control is a major challenge that cold chain logistics face.Design/methodology/approachThis research proposes a prediction model of refrigerated truck temperature and air conditioner status (air speed and air temperature) based on hybrid mayfly algorithm (MA) and extreme learning machine (ELM). To prove the effectiveness of the proposed method, the mayfly algorithm–extreme learning machine (MA-ELM) is compared with the traditional ELM and the ELM optimized by classical biological-inspired algorithms, including the genetic algorithm (GA) and particle swarm optimization (PSO). The assessment is conducted through two experiments, including temperature prediction and air conditioner status prediction, based on a case study.FindingsThe prediction method is evaluated by five evaluation indicators, including the mean relative error (MRE), mean absolute error (MAE), mean squared error (MSE), root mean square error (RMSE) and coefficient of determination (R2). It can be concluded that the biological algorithm, especially the MA, can improve the prediction accuracy. This result clearly proves the effectiveness of the proposed hybrid prediction model in revealing the nonlinear patterns of the cold chain logistics temperature.Research limitations/implicationsThe case study illustrates the effectiveness of the proposed temperature prediction method, which helps to keep the product fresh. Even though the performance of MA is better than GA and PSO, the MA has the disadvantage of premature convergence. In the future, the modified MA can be designed to improve the performance of MA-ELM.Originality/valueIn prior studies, many scholars have conducted related research on the subject of temperature monitoring. However, this monitoring method can only identify temperature deviations that have occurred that harmed fresh food. As a countermeasure, research on the temperature prediction of cold chain logistics that can actively identify temperature changes has become the focus. Once a temperature deviation is predicted, temperature control measures can be taken in time to resolve the risk.
Reassessing the feasibility of adopting dollarization in Latin America
Authors: Padilla León 
Published: March 2022

PurposeThis paper analyses the possibility of Latin America's (LA) major economies adopting dollarization, considering that in the last decade macroeconomic instability has once again challenged the ability of certain economies to properly manage their own currency.Design/methodology/approachTo determine the feasibility of adopting the US dollar as official currency, the author uses the framework of optimum currency area (OCA) theory, since, in fact, dollarization is an incomplete monetary union. The author uses a structural vector autoregressive (SVAR) model to identify what type of structural shock — country-specific, regional or global — prevails in LA economies. For this purpose, the US output is used to represent the global output and determine how the shocks of the US influence the output trajectory of each LA nation. The higher the influence of the US product, the lower the costs of adopting the US dollar.FindingsThe results of the variance decomposition show that the influence of the US shocks in the gross domestic product (GDP) trajectory of LA countries has significantly decreased over the last two decades, even in the currently dollarized economies. The estimates for Venezuela and Argentina show that the importance of US shocks in the trajectory of their GDP is low. Therefore, the cost of adopting the US dollar as the official currency would be high.Originality/valueIn view of hyperinflation and macroeconomic imbalances in certain LA nations, the dollarization debate has resurfaced in recent years. However, the literature that empirically evaluates the feasibility of adopting dollarization as a monetary system under current economic conditions is limited.
Antecedents of knowledge-seeking intentions and efforts within new product development teams: empirical evidence from knowledge-based Chinese companies
Authors: Zhang Wei , Jiang Yuan , Zhou Wenkai , Pan Wei 
Published: March 2022

PurposeThis study aims to examine the antecedents of knowledge-seeking intentions (SIs) and efforts within new product development (NPD) teams.Design/methodology/approachData was collected from 331 employees affiliated with 29 NPD teams across 18 Chinese firms in five high-tech and knowledge-based industries via an online assessment and a survey. Hierarchical linear modelling was used to test the hypotheses using HLM and Mplus software.FindingsThe results of this study show that intrinsic task motivation (IM) and personal task experience (TE) positively relate to SIs, whereas leadership support (LS) and shared culture (SC) negatively relate to knowledge-seeking efforts (SEs). SIs partially mediate the relationship between IM and SEs, while they fully mediate the relationship between TE and SEs. Additionally, customer orientation (CO) positively moderates the relationship between SIs and SEs.Research limitations/implicationsData collection was completed online by relying on an existing version of the Abedi Creativity Test. The samples involve 18 companies in a High-Tech Development Zone in China, which indicates limited generalizability.Practical implicationsEffective NPD depends on successful marketing–R&D integration and knowledge exchange within the NPD team. Besides, organizations need to find ways to stimulate NPD team members’ IM and also through various ways to inspire more efforts from team members under the condition of supportive leadership and culture.Originality/valueThis study contributes to the knowledge management and marketing literature on NPD teamwork by examining knowledge-seeking phenomena from the perspective of the internal knowledge market and contributes to knowledge-seeking research by revealing the antecedents of SIs and SEs at both the individual and organizational level.

Authors: Liu Weihua , Liang Yanjie , Shi Xiaoran , Gao Peiyuan , Zhou Li 
Published: March 2022

PurposeThe review aims to facilitate a broader understanding of platform opening and cooperation and points out potential research directions for scholars.Design/methodology/approachThis study searches Web of Science (WOS) database for relevant literature published between 2010 and 2021 and selects 86 papers for this review. The selected literature is categorized according to three dimensions: the strategic choice of platform opening and cooperation (before opening), the construction of an open platform (during opening) and the impact of platform opening and cooperation (after opening). Through comparative analysis, the authors identify research gaps and propose four future research agendas.FindingsThe study finds that the current studies are fragmented, and a research system with a theoretical foundation has not yet formed. In addition, with the development of platform operations, new topics such as platform ecosystems and open platform governance have emerged. In short, there is an urgent need for scholars to conduct exploratory research. To this end, the study proposes four future research agendas: strengthen basic research on platform opening and cooperation, deeply explore the dynamic evolution and cutting-edge models of platform opening and cooperation, analyze potential crises and impacts of platform openness and strengthen research on open platform governance.Originality/valueThis is the first systematic review on platform opening and cooperation. Through categorizing literature into three dimensions, this article clearly shows the research status and provides future research avenues.

Comparison between cotton fiber and cellulose powder for wastewater treatment efficiency with nano-crystalline TiO2 by sono-synthesis
Authors: Rubel Md Mehedi Hasan , Islam Syed Rashedul , Alassod Abeer , Farooq Amjad , Shen Xiaolin , Ahmed Taosif , Rashid Mohammad Mamunur , Zareen Afshan 
Published: March 2022

Purpose
The main purpose of this study was to prepare the cotton fibers and cellulose powder by a layer of nano-crystalline-titanium dioxide (TiO2) using the sol-gel sono-synthesis method to clean the wastewater containing reactive dye. Moreover, TiO2 nano-materials are remarkable due to their photoactive properties and valuable applications in wastewater treatment.

Design/methodology/approach
In this research, TiO2 was synthesized and deposited effectively on cotton fibers and cellulose powder using ultrasound-assisted coating. Further, tetra butyl titanate was used as a precursor to the synthesis of TiO2 nanoparticles. Reactive dye (red 195) was used in this study. X-ray Diffraction, scanning electron microscopy and Fourier transform infrared spectroscopy were performed to prove the aptitude for the formation of crystal TiO2 on the cotton fibers and cellulose powder along with TiO2 nanoparticles as well as to analyze the chemical structure. Decoloration of the wastewater was investigated through ultraviolet (UV-Visible) light at 30 min.

Findings
The experimental results revealed that the decolorization was completed at 2.0 min with the cellulose nano TiO2 treatment whereas cotton nano TiO2 treated solution contained reactive dyestuffs even after the treatment of 2 min. This was the fastest method up to now than all reported methods for sustainable decolorization of wastewater by absorption. Furthermore, this study explored that the cellulose TiO2 nano-composite was more effective than the cotton TiO2 nano-composite of decoloration wastewater for the eco-friendly remedy.

Research limitations/implications
Cotton fibers and cellulose powder with nano-TiO2, and only reactive dye (red 195) were tested.

Practical implications
With reactive dye-containing wastewater, it seems to be easier to get rid of the dye than to retain it, especially from dyeing of yarn, fabric, apparel, and as well as other sectors where dyestuffs are used.

Social implications
This research would help to reduce pollution in the environment as well as save energy and cost.

Originality/value
Decoloration of wastewater treatment is an essential new track with nano-crystalline TiO2 to fast and efficient cleaning of reactive dyes containing wastewater used as a raw material.
An analysis of post-pandemic scenarios: what are the prospects for the Caribbean cruise industry?
Authors: Ajagunna Ibrahim , Ilori Matthew Olusoji , McLean Eron 
Published: March 2022

PurposeThe cruise industry has been significantly impacted as a result of Covid-19. Some cruise lines have downsized, and many have cancelled ship orders while some vessels have been put on retainers. It is still uncertain how long this situation will continue. Even when cruise lines resume their services, the uptake is likely to be gradual because many traditional and potential cruisers may still be reluctant to travel because of the fear of contracting the disease. In addition, an enormous amount of money and time will be required to overhaul ships, re-plan service processes, re-certify crew and develop a new normal for how cruise businesses operate. An analysis of these issues forms the primary purpose of this study.Design/methodology/approachA qualitative approach was used to gather data and this was augmented by the personal industry experiences of the authors.FindingsSteady growth in the cruise industry came to an end during the last two years due to the unanticipated impact of the pandemic. SARS, Ebola and other diseases were much less significant in comparison. Many Caribbean islands have recently upgraded their ports to accommodate mega cruise ships as tourism is the main source of income for these islands. These investments run to millions of US dollars and as yet, there are no indications as to when the industry will recover.Research limitations/implicationsAccess to industry experts was not as broad-ranging as anticipated due to time pressures and the fact that it is difficult to schedule interviews by telephone or webinar with busy practitioners.Social implicationsThe pandemic will continue to impact the people of the Caribbean economically and socially, because of their dependence on tourism and especially cruise businesses.Originality/valueThe gradual re-entry of cruise operations represents a fourth phase in the development of the industry. This juncture is the most critical phase because of the many opinions surrounding vaccination. Cruising is unlike land-based tourism assets where a rapid reactive response is easier to facilitate. A health crisis at sea can have disastrous consequences, especially for small islands with limited facilities to deal with critical Covid-19 infections.
