Carbonate-based heterogeneous reacting systems are investigated for the applications of thermochemical carbon dioxide capture and energy storage. This paper aims to review recent progress in numerical modeling of thermal transport phenomena in such systems.

Calcium oxide looping is selected as the model carbonate-based reacting system. Numerical models coupling heat and mass transfer to chemical kinetics are reviewed for solar-driven calcium oxide looping on the sorbent particle, particle bed, and reactor levels.

At the sorbent particle level, a transient numerical model of heat and mass transfer coupled to chemical kinetics has been developed for a single particle undergoing cyclic calcination and carbonation driven by time-periodic boundary conditions. Modeling results show cycle times impact the maximum sorbent utilization and solar-to-chemical energy efficiency. At the reactor level, a model of heat and mass transfer coupled to chemical kinetics of calcination of a packed-bed reactor concept has been developed to estimate the reactor’s performance. The model was used to finalize reactor geometry by evaluating pressure drops, temperature distributions, and heat transfer in the reactor.

Successful solar thermochemical reactor designs maximize solar-to-chemical energy conversion by matching chemical kinetics to reactor heat and mass transfer processes. Modeling furthers the understanding of thermal transport phenomena and chemical kinetics interactions and guides the design of solar chemical reactors.

Effective product life cycle management will save costs and resources and improve customer service. Seeks to present a simulation model of the complete life cycle of a batch of products undergoing breakdown and repair and to show the ability of the model to predict future waste arisings and cost savings.

ARENA system simulation software is used for a novel application – a full life cycle of manufacture, use, repair and ultimate disposal. Two batches of products are compared: products with and without features which improve reliability. The number of replications for the Monte Carlo process can be calculated from the statistics of the model data.

The model demonstrates the predicted flows of products through their life cycle. The software has in‐built probability distributions that are not fully suitable for the problem modelled, requiring some artificial treatment, especially when using the delay function. The number of replications should be increased, requiring additional computer time.

The model is potentially valuable for producers wishing to predict the effect on future costs or the risk of modifying designs. The method can also be used to assist waste management using the output graphs of disposed components or products; hence the economics of component remanufacture or reuse can be modelled.

The paper presents the first known application of manufacturing system simulation software for modelling product life cycles.

The purpose of the paper is to address the following question: What can novels reveal about what leadership nonfiction sources miss or obscure?

The paper reviews the benefits that are derived from the use of literature in the examination of leadership, compares and contrasts three novel experiments in the examination of literature and leadership, and examines the impact of one approach as reflected in student assignments and exit interviews.

Student reflection papers morphed from descriptive reviews to reflections expressed through poetry, artwork and personal experiences. Students also deepened their views on what leadership is and means. Exit interviews revealed student significant reflection on personal views in a number of areas. The longitudinal follow up of students expanded their flexibility and ability to listen and understand how and why people approach leadership in different ways. They also felt it increased their openness to new or different approaches and encouraged them to think more independently.

One implication of the approach of this class is how the authors embraced questions to guide the students and faculty. Instead of listing topics and assigning categorical meaning, the approach of the class was organized around questions, such as, “is leadership real or imagined? Am I ready to take responsibility?

The power of storytelling is unmistakable. The value of storytelling is that it allows the reader to escape from the day-to-day challenges we face to find how others are facing challenges sometimes very similar to our own.

The article compares and contracts three experiments in the examination of literature and leadership. The paper then examines one approach to literature and leadership in terms of the impact on students (papers, exit interview and longitudinal follow-up). Findings are assessed with the works of Gardner, Bennis and Hartley stressing the possibilities of storytelling as a unique approach to studying and practicing leadership.

Introducing change is a difficult issue facing all health care systems. The use of various clinical governance levers can facilitate change in health care systems. The purpose of this paper is to define clinical governance levers, and to illustrate their use in a large-scale transformation.

The empirical analysis deals with the in-depth study of a specific case, which is the organizational model for Ontario’s cancer sector. The authors used a qualitative research strategy and drew the data from three sources: semi-structured interviews, analysis of documents, and non-participative observations.

From the results, the authors identified three phases and several steps in the reform of cancer services in this province. The authors conclude that a combination of clinical governance levers was used to transform the system. These levers operated at different levels of the system to meet the targeted objectives.

To exercise clinical governance, managers need to acquire new competencies. Mobilizing clinical governance levers requires in-depth understanding of the role and scope of clinical governance levers.

This study provides a better understanding of clinical governance levers. Clinical governance levers are used to implement an organizational environment that is conducive to developing clinical practice, as well as to act directly on practices to improve quality of care.

ALMOST EVERY communication we receive from manufacturers or suppliers, whether sent direct or from professional public relations companies, claims that the firm concerned is the most important firm in its category.

By engaging in critical literacy, participants theorized Blackness and antiblackness. The purpose of this study was to have participants theorize Blackness and antiblackness through their engagements with critical literacy.

The authors used a youth-centered and informed Black critical-race grounded methodology.

Participants’ unique and varied revelations of Blackness as Vitality, Blackness as Cognizance and Blackness as Expansive Community, served to withstand, confront and transcend encounters with antiblackness in English curricula.

This paper provides a model for how to engage Black youth as a means to disrupt anti-Black English education spaces.

This study provides a foundation for future research efforts of Black English outer spaces as they relate to English education. Findings in this study may also inform existing English educator practices.

This study theorized both the role and the flexible nature of Black English outer spaces. It defined the multi-ethnic nature of Blackness. It proposed that affirmations of Blackness sharpened participants’ critical literacies in Black English outer spaces as a transformative intervention to anti-Black English education spaces.

This paper sets out to describe transform methods to control vendor‐managed inventory (VMI). It aims to examine the limits of modelling approaches within control‐theoretic models.

Modelling was achieved with the Simulink package using the equations developed by Disney and Towill for a two‐tier VMI system. Discrete and continuous models were considered together with two forms of production delays: a finite delay and the Forrester exponential delay. Standard control engineering analyses of these delay representations were compared to illustrate how the system response and stability depend on their formulation and to determine the permissible gains.

Response by a discrete or continuous model to step inputs in sales rates depends on the type of delay representation but the responses do not differ by more than 5 per cent if the same delay form is used in the models. The prime effect of using a finite delay is to deepen the stock‐out and increase the required order rate compared with the same response observed with the use of exponential forms of delay. Total time for recovery is similar with all models. It is shown that the continuous model with an exponential delay is always stable and when using a fixed delay the continuous model can be made stable.

The models presented here illustrate that the various forms of control‐theoretic models present similar results irrespective of technique used, provided that they have the same delay type. The range of gains for the required order rate can be computed for any VMI system, knowing that they can be designed to guarantee stable operation.

This work extends that of Disney and Towill to include different modelling representations. It allows operational gains to be safely chosen for stable operation.

This paper aims to examine how auditors respond through audit fees and audit quality following disciplinary actions imposed by audit regulators in an emerging market setting.

This paper uses the disciplinary actions in 2017 against two major audit firms in China as an exogenous shock to examine the effect of tougher enforcement actions on auditor behavior as reflected in their emended audit fees and audit quality. This paper sampled from publicly listed firms in China with requisite data for the period 2015 through 2018. Using a difference-in-differences model, this paper examines whether the enforcement action (i.e. the suspension of audit firms) significantly impacted the audit fees and audit quality for clients of the disciplined audit firms (hereafter, suspended audit firms) in the two-year period postsuspension relative to audit firms that were not disciplined (hereafter, nonsuspended audit firms).

This paper finds evidence of increased audit fees and improved audit quality by the suspended audit firms relative to the nonsuspended audit firms in the two-year period postsuspension. These findings suggest that in contrast to symbolic disciplinary actions such as public censures documented in prior literature (Boone et al.,2015), tougher punitive disciplinary actions are followed by an increase in audit fees and an improvement in audit quality by the suspended audit firms. This paper also finds that the deterrent effect from the audit firm suspension is exclusive to the penalized audit firms and had no positive spillover effects on their peers.

A limitation of this study is the focus on the effect of audit firm suspension against two large local audit firms in China. Given the unique characteristics of the Chinese audit market and the Chinese regulatory environment, our findings may not be generalizable to audit firms in other countries and jurisdictions, especially where the audit market is dominated by the international Big 4 auditors that possess greater brand name capital than second-tier local audit firms.

This paper provides novel evidence on the impact of strengthened enforcement on auditor behavior in an emerging market setting. This paper contributes to the existing literature examining the impact of regulatory interventions on financial reporting outcomes and audit quality. While there is evidence on how regulations affect financial statement preparers’ demand for high audit quality, there is limited research on how regulatory interventions affect auditor’s incentive to supply higher audit quality. This paper also contributes to the scant existing evidence on the effect of disciplinary actions against audit firms in emerging economies.

We propose that strategies typically applied to support corporate entrepreneurship can be extended and applied at the national level, with the objective of stimulating not just entrepreneurship – but new ventures that grow. Only when individual ventures grow, can sustained growth occur at the level of the macroeconomy. Keys to growth of new ventures in this model include effective management of knowledge, resources, rewards, and infrastructure.
