Authors: Basu Saprativ , Chakrabarty Arijit , Nag Samik , Behera Kishore , Bandyopadhyay Brati , Grima Andrew Phillip , Ghosh Probal 
Published: April 2021

Purpose
The dryer feed chute of the pellet plant plays an important role in the pelletizing process. The chute discharges sticky and moist iron ore fines (<1 mm) to the inline rotary dryer for further processing. Since the inception of the installation of the dryer feed chute, the poor flowability of the feed materials has caused severe problems such as blockages and excessive wear of chute liners. This leads to high maintenance costs and reduced lifetime of the liner materials. Constant housekeeping is needed for maintaining the chute and reliable operation. The purpose of this study is to redesign the dryer feed chute to overcome the above challenges.

Design/methodology/approach
The discrete element method (DEM) has been used to model the flow of cohesive materials through the transfer chute. Physical experiments have been performed to understand the most severe flow conditions. A DEM material model is also developed for replicating the worst-case material condition. After identifying the key problem areas, concept designs were proposed and simulated to assess the design improvements to increase the reliability of chute operation.

Findings
Flow simulations correlated well with the existing flow behavior of the iron ore fines inside the chute. The location of the problematic areas has been validated with that of the previously installed chute. Subsequently, design modifications have been proposed. This includes modification of deflector plate and change in slope and cross-section of the chute. DEM simulations and analysis were conducted after incorporating these design changes. A comparison in the average velocity of particle and force on chute wall shows a significant improvement using the proposed design.

Originality/value
Method to calibrate DEM material model was found to provide accurate prediction and modeling of the flow behavior of bulk material through the real transfer chute. DEM provided greater insight into the performance of the chute especially modeling cohesive materials. DEM is a valuable design tool to assist chute designers troubleshoot and verify chute designs. DEM provides a greater ability to model and assess chute wear. This technique can help in achieving a scientific understanding of the flow properties of bulk solids through transfer chute, hence eliminate challenges, ensuring reliable, uninterrupted and profitable plant operation. This paper strongly advocates the use of calibrated DEM methodology in designing bulk material handling equipment.
COVID-19 and its impact on visitation and management at US national parks
Authors: Templeton A.J. , Goonan Kelly , Fyall Alan 
Published: April 2021

PurposeNational Park Service (NPS) units generate a significant economic impact for states and local gateway communities across the USA. Utah is home to 13 NPS units with visitation accounting for 18% of the state's US$9.75bn tourism economy in 2018. Twelve NPS units, including five national parks, are located in Southern Utah, driving an economy that is heavily dependent on tourism. This paper examines the challenges and opportunities for visits to national parks post-COVID-19, generally and in the specific context of Southern Utah. Although the assumption is that visits to national parks will recover quickly, this paper will critically examine how visitation may change and what adaptive measures and alternative forms of unit management may be necessary.Design/methodology/approachBy adopting a holistic-inductive paradigm, this paper utilizes a descriptive case study approach. Data were collected across a variety of mediums focusing on interviews with key stakeholders in and around Southern Utah.FindingsThe results from this study highlight the various challenges faced in parks and gateway communities vis-à-vis changing patterns of visitation, adaptive measures and alternative forms of unit management necessary due to COVID-19 and their impact on the future management and marketing of national parks for touristic purposes.Originality/valueThis paper examines the impacts of COVID-19 on an often-neglected yet significant area within tourism, yielding implications for industry, visitors and destination communities.

Authors: Paletta Angelo , Alimehmeti Genc , Mazzetti Greta , Guglielmi Dina 
Published: April 2021

PurposeThis study explores the factors that explain the adoption of innovative teaching practices within schools and how this is determined by the different perceptions of principals and teachers.Design/methodology/approachThe authors use the self-other agreement to measure the difference between the principal and teachers' rating based on the responses of 255 principals and 10,415 teachers, applying polynomial regression with surface analysis to examine the in-agreement/disagreement of self- and other-ratings.FindingsResults indicate that schools where principals and teachers agree on the level of collaborative culture, learning climate, professional development and instructional leadership are associated with higher innovative teaching practices, creating opportunities for stimulating learning environments. In addition, the adoption of innovative professional practices is more likely to result when there is disagreement with teacher over-rating the factors.Practical implicationsIt has practical implications for developing strategies aimed at encouraging the implementation of innovative teaching practices among teachers and it extends the research on teachers' professional practices by using self-other agreement data collection method and surface analysis.Originality/valueThe vast collection of data provide a unique investigation opportunity of the effects of collaborative culture, learning climate, professional development and instructional leadership on innovative teaching in Italy.
Early childhood centre directors coping with stress: firefighters and oracles
Authors: Kristiansen Elsa , Rydjord Tholin Kristin , Bøe Marit 
Published: April 2021

PurposeEarly childhood education (ECE) centre directors have to meet various leadership demands at present, and this has become even more important in a time of extensive policy changes. There is little research on work-related stress from the perspective of ECE directors. The purpose of this study was therefore to enhance one’s knowledge of (a) what ECE centre directors perceive to be work-related stressors; (b) what causes stressful situations; and (c) how they cope with the identified stressors.Design/methodology/approachEighty directors from three groups in part-time leadership education programmes participated between 2017 and 2020. Data was collected through class discussions and whiteboard notes, focus group interviews with 24 directors and student role-play scenarios that were acted out in class.FindingsThe findings illustrated three main categories of stressors: an overwhelming number of administrative tasks, leading others and lack of social support. Unexpected findings were a lack of knowledge about coping strategies and a need for more resources so that directors can focus on pedagogical leadership.Research limitations/implicationsThe study has been done in the Norwegian educational context with Norwegian ECE centre directors participating in a leadership programme. Several qualitative methods were used on three groups of centre directors. These limitations must be considered when generalizing.Practical implicationsThe results can be used as guidance for supporting ECE centre directors, owners and policymakers in how to develop and sustain leadership and increase well-being and work satisfaction.Originality/valueThe current study is among the few ones focussing on perceived stressors among centre directors and the consequent coping in the early childhood setting.
Emotional self-efficacy and workplace psychological health in emergency dispatchers
Authors: Huard Charlotte , Deschênes Andrée-Ann , Rioux Charles-Antoine 
Published: April 2021

PurposeThe main purpose of this research is to establish the relationships between emotional self-efficacy and workplace psychological health for emergency dispatchers.Design/methodology/approachA correlational design was used to validate results of the study. Between December 2018 and February 2019, a secure online questionnaire was sent to dispatchers through four emergency call centers. Participation was voluntary. A total of 257 emergency dispatchers participated in this study. Gilbert et al.’s (2011) scale of workplace psychological health and Deschênes et al.’s (2019) scale of emotional self-efficacy were used. Multiple linear regression and Pearson's correlation tests were run using the SPSS 25 program in order to establish relationships between the two variables.FindingsA total of three emotional competencies positively affect workplace psychological well-being (PWB), i.e. self-efficacy beliefs on managing one's own emotions, on managing other people' emotions and on using one's own emotions. As regards to psychological distress (PD), it is negatively correlated to self-efficacy beliefs on managing and using one's own emotions.Research limitations/implicationsOne of the study's theoretical contributions is to broaden the scientific knowledge of emergency service dispatching, in addition to opening up a new field of study in workplace people management.Practical implicationsThese scientific findings therefore show the importance of emotional self-efficacy in the workplace. The manager or the dispatch leader should focus on developing the following three emotional skills: self-efficacy in managing emotions, managing the emotions felt by others and using emotions. Training allowing the development of these emotional skills should be considered and would be beneficial for emergency dispatchers to maximize their well-being at work.Originality/valueTo the best of the authors’ knowledge, no other study has focused on emergency dispatchers and included the emotional self-efficacy and workplace mental health variables.
Being mobile: a call for collaborative innovation practices?
Authors: Antonczak Laurent , Burger-Helmchen Thierry 
Published: April 2021

Purpose
The purpose of this study is to examine mobile technology as being a key apparatus and interface for collaborative innovation, which allows organisations to develop their information ecology.

Design/methodology/approach
The qualitative research was performed by in-depth interviews, observations and field notes. The eight main interviews are supported by an interdisciplinary narrative literature review of knowledge management and associated fields.

Findings
This study validates the following propositions: mobile technology can offer users timely information, mobile technology can foster collaboration beyond physical and organisational boundaries, in general, mobile technology enables a wider amount of interactions between people. Thereby, this paper draws some implications about the knowledge management of creative (and non-creative) workers.

Research limitations/implications
The collected data sheds light on how organisations and individuals positioned themselves about mobile technology co-creative practices before the COVID era. Therefore, it shall be pertinent to further investigate these findings through a quantitative approach to better ascertain path models and to strengthen the new results with another qualitative perspective, in the post-COVID era.

Practical implications
The study highlights how mobile devices are facilitating collaborative innovation practices by improving management decisions, enabling new business and/or operating models, developing a flow of ideas inner/outer an organisation and fostering the ability to make innovation.

Social implications
Mobile technology transforms the way to work (knowledge creation and/or conversion) and it changes the relations between collaborators in a working environment (beyond physical boundaries). This study deciphers how a creative and/or decision-making person can change their work schedule and/or routines based on the use of mobile devices.

Originality/value
The added value of this transdisciplinary study is that it improves research on collaborative innovation and collective knowledge by revealing three pertinent characteristics of mobile technology: enabling quick decision; connecting with a glocal network and fostering collective creativity. It also creates a bridge between the fields of education and business.

Authors: Karayianni Eva , Hadjielias Elias , Glyptis Loukas 
Published: April 2021

Purpose
The purpose of this paper is to study the way in which family ties influence the entrepreneurial preparedness of the diaspora family business owner.

Design/methodology/approach
In-depth interviews were carried out with 15 Cypriot family business owners hosted in various countries. The paper draws on social capital theory and uses an abductive analytical approach.

Findings
The findings of this paper illustrate that family ties coming from the family across borders play a significant role for diaspora family business owners’ entrepreneurial preparedness. Hidden values deriving from the interpersonal relationships within the family across borders drive the diaspora family business owners to learn upon self-reflection and become entrepreneurially prepared, led by both urgency and esteem.

Practical implications
This study provides practical implications for the entrepreneurial preparedness of diaspora family business owners and those who wish to become family business owners in a diaspora context.

Originality/value
This study contributes theoretically through the conceptualization of “family across borders social capital” and “diaspora entrepreneurial preparedness”. It also contributes empirically to the fields of diaspora family business, entrepreneurial learning and diaspora entrepreneurship through new knowledge regarding the role of family across borders social capital in the entrepreneurial preparedness of the diaspora family business owner.
Using accounting ratios to measure construction industry lag
Authors: Killingsworth John , Mehany Mohammed Hashem , Kim Jeff 
Published: April 2021

Purpose
The apparent lag between macro-economic behavior and financial implications in the construction industry is yet to be examined. The purpose of this paper is to understand the nature of the lag and the relationship between economic changes from year-to-year and the impact on the financial status of construction companies.

Design/methodology/approach
Correlation was made between US economic growth and construction industry financial indicators over a 28-year period. Cumulative per cent growth in US GDP was considered an independent variable, while nine financial ratios were calculated and considered dependent variables in this study.

Findings
The results of this study found that correlation improved when considering lag of two, three or sometimes four years after the economic event. Some financial ratios proved more sensitive than others, supporting the hypothesis of this study.

Research limitations/implications
The practical application of this study for construction companies is to understand how the construction industry lag impacts financial behavior. It therefore informs managerial decisions related to solvency, liquidity, equity structure and managerial practices; all of which are measured by financial ratios.

Practical implications
This study was intended to advance the research in this area and also to serve to strengthen industry members in their financial management of construction companies. Economic dynamics have long-lasting implications, which can be addressed through an increased focus on managing financial health.

Originality/value
Though the lag is intuitively known and has been studied from market perspectives, there is a lack of empirical study evaluating the impact of lag on financial key performance indicators.
Significant factors associated with malaria spread in Thailand: a cross-sectional study
Authors: Krainara Patcharaporn , Dumrongrojwatthana Pongchai , Bhattarakosol Pattarasinee 
Published: April 2021

PurposeThis paper aims to uncover new factors that influence the spread of malaria.Design/methodology/approachThe historical data related to malaria were collected from government agencies. Later, the data were cleaned and standardized before passing through the analysis process. To obtain the simplicity of these numerous factors, the first procedure involved in executing the factor analysis where factors' groups related to malaria distribution were determined. Therefore, machine learning was deployed, and the confusion matrices are computed. The results from machine learning techniques were further analyzed with logistic regression to study the relationship of variables affecting malaria distribution.FindingsThis research can detect 28 new noteworthy factors. With all the defined factors, the logistics model tree was constructed. The precision and recall of this tree are 78% and 82.1%, respectively. However, when considering the significance of all 28 factors under the logistic regression technique using forward stepwise, the indispensable factors have been found as the number of houses without electricity (houses), number of irrigation canals (canals), number of shallow wells (places) and number of migrated persons (persons). However, all 28 factors must be included to obtain high accuracy in the logistics model tree.Originality/valueThis paper may lead to highly-efficient government development plans, including proper financial management for malaria control sections. Consequently, the spread of malaria can be reduced naturally.
Cross-cultural effects on graphical password memorability and design
Authors: Mohamed Mona , Porterfield Tobin , Chakraborty Joyram 
Published: April 2021

Purpose
This study aims to examine the impact of cultural familiarity with images on the memorability of recognition-based graphical password (RBG-P).

Design/methodology/approach
The researchers used a between-group design with two groups of 50 participants from China and the Kingdom of Saudi Arabia, using a webtool and two questionnaires to test two hypotheses in a four-week long study.

Findings
The results showed that culture has significant effects on RBG-P memorability, including both recognition and recall of images. It was also found that the login success rate depreciated quickly as time progressed, which indicates the memory decay and its effects on the visual memory.

Research limitations/implications
Collectively, these results can be used to design universal RBG-Ps with maximal password deflection points. For better cross-cultural designs, designers must allow users from different cultures to personalize their image selections based on their own cultures.

Practical implications
The RBG-P interfaces developed without consideration for users’ cultures may lead to the construction of passwords that are difficult to memorize and easy to attack. Thus, the incorporation of cultural images is indispensable for improving the authentication posture.

Social implications
The development of RBG-P with cultural considerations will make it easy for the user population to remember the password and make it more expensive for the intruder to attack.

Originality/value
This study provides an insight for RBG-P developers to produce a graphical password platform that increases the memorability factor.

Findings
A framework was proposed which is viable for designing an IoT-based smart warehouse infrastructure. Based on the data collected from a case company, the proposed smart warehouse infrastructure design successfully implemented real-time visibility and traceability and improved overall warehouse efficiency.

Research limitations/implications
While the framework in this research was carried out in one of the developing counties, the study could be used as the basis for future research in a smart warehouse, IoT and related topics.

Originality/value
This research enhances the limited knowledge to establish the IoT infrastructure for a smart warehouse to enable real-time visibility and traceability. This study is also the first to specifically propose a framework for designing an IoT-based smart warehouse infrastructure. The proposed framework can motivate companies in developing countries to deploy efficient and effective smart warehouses using IoT to drive the countries’ economic growth.
Gender diversity on board of directors: comprehensive analysis of female directorate networks and the linkage between busyness and performance
Authors: Safari Maryam 
Published: April 2021

PurposeDrawing from social capital theory, this study aims to investigate the manifested critical barriers in deriving and implementing gender diversity policies, paying particular attention to the role multiple directorships play in shaping the directors’ behavior and the dynamic of the board of directors. The study comprehends social capital as a multi-dimensional concept and uses combinations of interconnected internal, external, expressive and instrumental networks.Design/methodology/approachThe study uses a mixed-method approach through which the quantitative approach is supplemented by a qualitative research method to comprehensively examine the development and impact of female directors’ networks in Australia. To do so, a large data set consisting of 2,527 observations of all Australian firms and data emerged from semi-structured interviews with female directors were brought together and analyzed.FindingsThe findings reveal an inverted U-shaped relationship between the size of women’s directorate networks and firm performance. The study additionally explicates the key moderating factors influencing the optimal number of multiple directorships. The key power-based and psychological well-being-related benefits of the inter- and intra-organizational interactions and “open” directorate networks for individual directors are further discussed. The findings also elucidate the status quo vis-à-vis labyrinth metaphor and excessive numbers of directorships.Social implicationsThe study should be of interest to those interested in effective gender diversity management. The findings would assist in enabling tangible outcomes for women through advanced processes and systematic investment in and institutionalization of well-structured, equitable opportunities provided via gender-responsive policies dedicated to the education and training of future female directors.Originality/valueCalling for social dialogues and discussions on non-financial factors, this study adds to the scarce literature on influential factors related to diversity management policies and practices on the board of directors.
