Purpose The purpose of this paper is to examine the coupled heat and mass transport of different shaped porous moist objects in a rectangular channel under the effects of convective drying. Numerical simulations were performed under turbulent conditions for cylindrical, triangular and rectangular shaped different food products in a two-dimensional channel. Design/methodology/approach Finite element method was used for the unsteady problem and, effects of drying air velocity (AV) and temperature on transport mechanism were evaluated. Three different food materials were used for the circular shaped object and drying performance of the products under different conditions was compared. Findings Results showed that, changing the air temperature has an important effect on drying for all shaped objects and all materials. The same effect was seen for the AV as, increasing the velocity had positive effects on drying. Two identical objects were placed in the channel one behind the other, and this configuration showed that location of the object in the channel is also important for drying. The moisture content in the object at the front is lower than in the object behind at the end of drying. Originality/value This paper can provide technical support to optimize drying performance in the industry with comprehensive data for the process.

Purpose The purpose of this paper is to explore healthcare waiting time and the negative and positive effects (i.e. the dual effects) it has on outpatient satisfaction. Design/methodology/approach Self-administered surveys with 334 outpatients and follow-up interviews with 20 outpatients in three large hospitals in Taiwan were conducted to collect data. Findings Quantitative surveys demonstrated that perceived waiting time correlated with satisfaction negatively first but then positively. Satisfaction also correlated with doctor reputation and patient sociability. Follow-up qualitative interviews further revealed that, for some patients, waiting contributed positively to patient evaluations through signaling better healthcare quality and facilitating social interaction. Originality/value This research demonstrated the possibility that waiting might have positive effects on healthcare satisfaction. It also identified variables that could produce greater positive perceptions during hospital waiting and underlying mechanisms that could explain how the positive effects work. This research may potentially help hospitals with a better understanding of how they can improve patients’ waiting experiences and increase satisfaction.

PurposeThis study seeks to investigate how leader ability and diverse organisational cultures (OC) act to influence employee creativity in manufacturing organisations. By leveraging the multifaceted nature of the competing values framework (CVF), this study examines the growing deterioration of employee creativity through the lens of four OC quadrants within the Nigerian manufacturing industry and further investigates how distinct OCs and leader ability can aid to bolster employee creativity. The CVF is a model used to assess organisational cultures, irrespective of their industry, for the overarching purpose of improving organisational performance.Design/methodology/approachThe target population consists of employees of research and development (R&D) and information technology (IT) in the headquarters of 21 manufacturing organisations. Our useable sample consisted of 439 responses from the Nigerian manufacturing industry.FindingsResults indicated that leader ability and adhocracy OC have positive effects on employee creativity. Market and clan OC have negative effects on employee creativity. Likewise, leader ability dampens the effects of adhocracy OC on employee creativity and reinforces the market OC effect on employee creativity.Originality/valueThis study provides novel insights that challenges several controversial and contemporary postulations of extant research which theorise the OC–employee creativity relationships. By leveraging the construct of leader ability, unique contributions are also made to provoke congruence.

Purpose The COVID-19 pandemic has affected psychotherapy practice. A common change is a move to online sessions over video calls. In their therapeutic community (TC) for those with personality disorders, the authors have used video calls but not all clients could work in this way. The authors decided to meet patients outside and walked with them while adhering to government guidelines. This study aims to present the authors’ experience with one client who was interviewed afterwards about the experience. Design/methodology/approach A total of 10 walking therapy sessions of 60-min duration were conducted with the patient. After the sessions, both the patient and therapist were interviewed about their experience. The resulting interviews with both patient and therapist were thematically analysed independently by both authors. Findings There were common themes to both the client and therapist’s account following thematic analysis. These were: modelling and normalising in the real world, replacing what COVID-19 had taken away from the TC experience, changes at home, therapist disclosure, outcomes and good endings and being outside of the clinical environment. Research limitations/implications The authors have presented a single case of the patient and therapist experience of outdoor therapy sessions in a TC context response to the COVID-19 pandemic. The findings are not generalisable and can only provide a suggestion at the positive potential for working in this way. The authors hope that the positive effects of outdoor therapy noted here may inspire other clinicians to consider similar novel approaches in their work. Originality/value This study describes a novel way that a TC has adapted to the COVID-19 pandemic.

Purpose The purpose of this paper is to underscore the need for developing a meta-intelligence in companies based on a conceptual framework for combining artificial and human intelligence. Design/methodology/approach This is a conceptual paper, which draws on the insights from extant theoretical and empirical research. Findings In light of a growing trend towards artificial intelligence (AI), most companies face substantial difficulties, which often derive from an excessive emphasis on merely replacing human intelligence by means of AI. To capture the complementary benefits of artificial and human intelligence beyond mere cost savings, firms do not only need to enhance their advanced analytics while continuing to develop their human intelligence. Rather, they additionally need a meta-intelligence for transforming their intelligence architecture in line with corporate strategy. Consequently, the firms need intelligence3 – comprising AI, human intelligence and the meta-intelligence. Originality/value The new concept of a meta-intelligence for renewing and recombining artificial and human intelligence helps to reconcile diverse findings in prior research. Without this meta-intelligence, most AI initiatives will be isolated endeavors, which may have positive effects but likely will not live up to the expectations.

Purpose The purpose of this paper is to explore the determinants of family business owners’ intrafamily succession intention based on the theory of planned behavior and neo-institutional theory. Design/methodology/approach National survey data were collected from Chinese private firms in 2010, and a sample of 804 family firms was used to test the hypotheses. Findings At the micro level, familism, intrafamily succession regulation and family control have positive effects on owners’ intrafamily succession intention. At the macro level, district succession orientation, which is the district prevalence of intrafamily succession practice, has a positive effect on owners’ intrafamily succession intention. Additionally, the district succession orientation weakens the positive effects of intrafamily succession regulation and family control. Originality/value The paper contributes to the understanding of family business owners’ intrafamily succession intention from both micro and macro perspectives. Besides, it also contributes to the integration of micro and macro research by examining the interaction effects.
