Patient length of stay (LOS) is an important indicator of emergency department (ED) performance. Investigating factors that influence LOS could thus improve healthcare delivery and patient safety. Previous studies have focused on patient-level factors to explain LOS variation, with little research into service-related factors. This study examined the association between LOS and multi-level factors including patient-, service- and organization-level factors.

This study uses a retrospective observational design to identify a cohort of patients from arrival to discharge from ED. A year-long data regarding patients flow trhoguh ED were analyzed using analytics techniques and multi-regression models. The response variable was patient LOS, and the independent variables were patient characteristics, service-related factors and organizational variables.

The findings of this study showed that older patients, middle triage and hospitalization were all associated with longer LOS. Service-related factors such as complexity of care provided, initial ward designation and ward transfer had a significant impact as well. Finally, prolonged LOS was associated with a higher ratio of patients per medical doctor and per nurse. In contrast, a higher number of residents in the ED were associated with longer patient LOS.

Previous studies on patient LOS have focused on patient-level factors, with little research on service-related factors. This study has addressed that gap by examining the association between LOS and multi-level factors including patient-, service- and organization-level factors. Patient-level factors included demographics, acuity, arrival shift, arrival mode and discharge type. Service-level factors consisted of first ward, ward transfer and complexity of care provided. Organizational factors consisted of three ratios: patients per MD, patients per nurse and patients per resident. The results add to the current understanding of factors that increase patient LOS in EDs and contribute to the body of knowledge on ED performance, operation management and quality of care. The study also provides practical and managerial insights that could be used to improve patient flow in EDs and reduce LOS.

This study tested a structural equations model of the five French and Raven bases of supervisory power (coercive, reward, legitimate, expert, and referent), styles of handling conflict with supervisor (problem solving and bargaining), and job performance. Employees (N = 1,116) completed questionnaires on power and conflict styles, and their job performance was evaluated by their respective supervisors (N = 398). The data were aggregated for the subordinates associated with a given manager (N = 398) to make sure that independent observation assumption is not violated. The LISREL 8 analysis of data indicates that legitimate power influenced referent power positively and coercive power negatively, and reward and legitimate powers positively influenced expert power, which in turn, positively influenced referent power. Referent power, in turn, positively influenced problem solving (i.e., using more integrating and less avoiding styles) and negatively influenced bargaining (i.e., using more dominating and less obliging styles) conflict‐management styles, and finally, problem solving style, but not bargaining style, positively influenced job performance.

The purpose of this paper is to provide a critical and in‐depth review of the present status and recent developments in synthetic methodologies, reaction engineering, process design and quality control aspects associated with the manufacture of mono and multifunctional acrylate monomers.

This paper reviews commercially important UV cure mono and multifunctional acrylate monomers. It covers their synthesis, catalyst, and appropriate solvents for azeotropic removal of byproducts. The detail discussion on catalysis, basis of design of reactors and commercial plant and the process engineering associated with the manufacture has been supported through citation of synthesis of various acrylate monomers. The methodologies adopted for determination of physical, chemical and compositional characterisation of acrylate monomers have been presented. In addition, the guidelines regarding the bulk storage and commercial handling of acrylates have been reviewed.

The reaction engineering of esterification reaction between acrylic acid and polyol has been worked out to provide the basis for selection of reactors. The reaction has been modeled as a series – parallel complex reaction for providing explanation for generation of various byproducts/adducts and multiple esters.

The detailed discussion on formation, characterisation and treatment of Michael adducts and purification of acrylate monomers will be relevant for new researchers for further development. A review of guidelines on selection of homogenous and heterogeneous catalysts for synthesis of acrylate monomers has been presented.

Since the related literature on acrylate monomers is scarce, scattered and proprietary, the consolidated coverage in one paper will be useful.

Genetic and environmental factors are associated with psychosis risk, but the latter present more tangible markers for prevention. We conducted a theoretical exercise to estimate the proportion of psychotic illnesses that could be prevented if we could identify and remove all factors that lead to increased incidence associated with ethnic minority status and urbanicity. Measures of impact by population density and ethnicity were estimated from incidence rate ratios [IRR] obtained from two methodologically‐similar first episode psychosis studies in four UK centres. Multilevel Poisson regression was used to estimate IRR, controlling for confounders. Population attributable risk fractions [PAR] were estimated for our study population and the population of England. We considered three outcomes; all clinically relevant ICD‐10 psychotic illnesses [F10‐39], non‐affective psychoses [F20‐29] and affective psychoses [F30‐39]. One thousand and twenty‐nine subjects, aged 18‐64, were identified over 2.4 million person‐years. Up to 22% of all psychoses in England (46.9% within our study areas) could be prevented if exposures associated with increased incidence in ethnic minority populations could be removed; this is equivalent to 66.9% within ethnic minority groups themselves. For non‐affective psychoses only, PAR for population density was large and significant (27.5%); joint PAR with ethnicity was 61.7%. Effect sizes for common socio‐environmental risk indicators for psychosis are large; inequalities were marked. This analysis demonstrates potential importance in another light: we need to move beyond current epidemiological approaches to elucidate exact socio‐environmental factors that underpin urbanicity and ethnic minority status as markers of increased risk by incorporating gene‐environment interactions that adopt a multi disciplinary perspective.

Positive transformative leadership development practices in health care are perhaps the most important pathway that, collectively, can be pursued while heading towards a post-corona virus disease 2019 world, and race towards 2030. As a practitioner paper, based on front line and leadership experience, this study aims to argue that we need transformational leaders who will go beyond knowing to practice and implementation. While the findings from research is presented from different organisations and companies, they all have something in common – people. Hence, important lessons can be extrapolated to health-related organisations in the future.

The approach is based on practical research findings based on the literature. The approach uses real practical examples from companies and organisations to demonstrate the need for a new, radical way forward.

The findings from the literature clearly indicate that mindfulness-based transformative leadership development program is a worthwhile investment for decision-makers and organisations. A new transformative leader for the future of health care needs to be developed with care with investment in that development.

Implications of this paper show that health-care organisations need to begin this journey. There is a paucity in the literature to demonstrate the implementation of mindfulness-based transformative leadership development programs.

Organisations of the future face even greater challenges brought about by intelligent technology, new pandemics and even tighter government regulation. The time to prepare for such eventualities is now. This is not a choice but an imperative for organisations to know what to do rather than react with regret.

There is a paucity in the health-care literature that tracks, measures, and reports on the long-term results of a mindfulness-based transformative leadership development program. This needs to be addressed, and health care should be a leader in the field of mindfulness and transformative leadership of the future.

Drawing upon person–supervisor fit theory, a model is developed to illustrate how leader–member trait mindfulness (in)congruence may impact leader–member exchange (LMX) and how such trait mindfulness (in)congruence can indirectly influence taking charge.

Polynomial regression and response surface methodology are used to analyze 237 valid matched leader–member dyads.

LMX increases as leaders' and members' trait mindfulness become more aligned; LMX is higher when leader–member dyads are congruent at high levels (vs low levels). In the case of incongruence, LMX is higher when the member's trait mindfulness exceeds that of the leader. Furthermore, the relationship between leader–member trait mindfulness (in)congruence and taking charge is mediated by LMX.

The joint and interactive role of high trait mindfulness in leader–member dyads can help them to generate high-quality interpersonal exchange, as well as to cope with challenges posed by present and future changes.

The linear, nonlinear, simultaneous and interactive effects of dyadic trait mindfulness expand previous research, clarifying that the evaluation of leader–member congruence and incongruence at various degrees, and for various patterns of trait mindfulness, is more informative than examining the direct effect alone.

This paper aims to examine the historical evolution and popularity of activity-based thinking in management accounting. As an organising framework, this paper applies the lens of management fashion theory, which is a perspective that is well suited to the examination of the lifecycles of management accounting concepts and ideas.

This paper pursues a bibliographic approach to better understand the past and present state of activity-based thinking. Thus, this paper attempts to piece together a mosaic picture by synthesising existing research on activity-based thinking from a wide range of academic and practitioner-oriented sources.

While the original activity-based costing (ABC) model has evolved and broadened and has generated new related concepts, studies suggest that it is not as successful as accounting concepts such as the balanced scorecard. The overall popularity trajectory of activity-based thinking can be considered to be negative, and it is currently not receiving much attention in accounting journals.

This paper is based on desk research and is limited by a reliance on secondary sources. In addition, it may be subject to the authors’ own biases when it comes to defining relevant articles studied.

This paper provides more insight into the evolution and popularity of activity-based thinking and discusses some of the reasons why it is not more widely used in practice.

Although many studies have examined the diffusion of ABC-related techniques, most are quite dated. More than 30 years have passed since the coining of the ABC term, and the time is ripe to provide a historical re-examination of the impact of this type of thinking in the field of accounting and to consider the latest developments and trends.

The area behind the engine/wing junction of conventional civil aircraft configurations with underwing-mounted turbofans is susceptible to local flow separation at high angles of attack, which potentially impacts maximum lift performance of the aircraft. This paper aims to present the design, testing and optimization of two distinct systems of fluidic actuation dedicated to reduce separation at the engine/wing junction.

Active flow control applied at the unprotected leading edge inboard of the engine pylon has shown considerable potential to alleviate or even eliminate local flow separation, and consequently regain maximum lift performance. Two actuator systems, pulsed jet actuators with and without net mass flux, are tested and optimized with respect to an upcoming large-scale wind tunnel test to assess the effect of active flow control on the flow behavior. The requirements and parameters of the flow control hardware are set by numerical simulations of project partners.

The results of ground test show that full modulation of the jets of the non-zero mass flux actuator is achieved. In addition, it could be shown that the required parameters can be satisfied at design mass flow, and that pressure levels are within bounds. Furthermore, a new generation of zero-net mass flux actuators with improved performance is presented and described. This flow control system includes the actuator devices, their integration, as well as the drive and control electronics system that is used to drive groups of actuators.

The originality is given by the application of the two flow control systems in a scheduled large-scale wind tunnel test.

Drawing upon the creativity interaction theory and expectation-identity perspective, the purpose of this paper is to construct a chain mediation model of the influence of workplace status on individual creativity from the perspective of expectation identity and to explore the moderating effect of prosocial motivation in this model.

This study reached 529 employees from 35 enterprises as the investigation objects and used structural equation model and hierarchical regression for data analysis. Data on workplace status, prosocial motivation, creativity expectations and creativity role identity were collected at Time Point T1, and individual creativity was collected at time point T2 (one month later).

The results reveal that: workplace status has a significantly positive effect on creativity; creativity performance expectations and creativity role identity have partial mediating effect in the relationship between workplace status and creativity, respectively; creativity performance expectations and creativity role identity play a chain double mediation role in the relationship between workplace status and creativity; and prosocial motivation moderates the relationship between workplace status and creativity and further moderates the chain double mediation effect of creativity performance expectations and creativity role identity.

In existing studies, conclusions about the relationship between workplace status and individual creativity could be divided into three viewpoints: positive, negative and U-shaped. These inconsistent findings on the relationship between workplace status and creativity imply that the relationship is complex and not fully elucidated. This may be attributed to the fact that workplace status is influenced by cultural factors and research objects. This study reinterprets the relationship between workplace status and individual creativity through the lens of creativity interaction theory and demonstrates the significance of employee workplace status in the Chinese context.
