Abstract
Purpose
Enzymes play a pivotal role in orchestrating essential biochemical processes and influencing various cellular activities in tissue. This paper aims to provide the process of enzyme diffusion within the tissue matrix and enhance the nano system performance by means of the effectiveness of enzymatic functions. The diffusion phenomena are also documented, providing chemical insights into the complex processes governing enzyme movement.
Design/methodology/approach
A computational analysis is used to develop and simulate an optimal control model using numerical algorithms, systematically regulating enzyme concentrations within the tissue scaffold.
Findings
The accompanying videographic footages offer detailed insights into the dynamic complexity of the system, enriching the reader’s understanding. This comprehensive exploration not only contributes valuable knowledge to the field but also advances computational analysis in tissue engineering and biomimetic systems. The work is linked to biomolecular structures and dynamics, offering a detailed understanding of how these elements influence enzymatic functions, ultimately bridging the gap between theoretical insights and practical implications.
Originality/value
A computational predictive model for nanozyme that describes the reaction diffusion dynamics process with enzyme catalysts is yet not available in existing literature.

Abstract
In our societal context, the neoliberal competitive and knowledge-oriented culture still exerts a stranglehold on teachers' sense of professional autonomy giving rise to a deficit image of them as ‘excessively entitled’. The purpose of this chapter is to eschew this deficit view of teachers by bringing their agentive side to the fore. First, it explores the concept of ‘excessive teacher entitlement’ in terms of the prevalent characteristics of the culture of teaching in schools and the nature of authority wielded by teachers in this culture and its negative consequence on student learning using an excerpt from an English as Second Language (ESL) classroom in India where this study is set. This episode helps expose the teacher's unawareness of the gaps between their intention and action, a hallmark of excessive entitlement. Second, it juxtaposes an alternative image of ‘teacher as researcher’ to foreground teachers' ‘transformative activist stance’ which revolves around their ideological becoming in agentively striving to realise their ‘best-loved self’. Framed within Vygotskian Cultural-Historical Activity Theory, the principle of ‘double stimulation’ provides a powerful analytical lens to unpack the complex discursive dynamics of their practice nested within historically developing contradictions. These contradictions work tacitly to drive a wedge between teachers' intentions and action making them feel excessively entitled to passively acquiesce with the existing order of things. This study provides some signposts for teacher education about creating an environment where teachers can reclaim their transformative agency freeing themselves from the ‘excessive entitlement’ that binds their practice to the status quo and diminishes their relationships with students.

Abstract
Purpose
This study evaluates the potential of using the material extrusion (MEX) process for recycling waste tire rubber (WTR). By investigating the process parameters, mechanical behaviour and morphological characterisation of a thermoplastic polyurethane-waste tire rubber composite filament (TPU-WTR), this study aims to establish a framework for end-of-life tire (ELT) recycling using the MEX technology.
Design/methodology/approach
The research assesses the impact of various process parameters on the mechanical properties of the TPU-WTR filament. Hysteresis analysis and Poisson’s ratio estimation are conducted to investigate the material’s behaviour. In addition, the compressive performance of diverse TPU-WTR triply periodic minimal surface lattices is explored to test the filament suitability for printing intricate structures.
Findings
Results demonstrate the potential of the TPU-WTR filament in developing sustainable structures. The MEX process can, therefore, contribute to the recycling of WTR. Mechanical testing has provided insights into the influence of process parameters on the material behaviour, while investigating various lattice structures has challenged the material’s capabilities in printing complex topologies.
Social implications
This research holds significant social implications addressing the growing environmental sustainability and waste management concerns. Developing 3D-printed sustainable structures using recycled materials reduces resource consumption and promotes responsible production practices for a more environmentally conscious society.
Originality/value
This study contributes to the field by showcasing the use of MEX technology for ELT recycling, particularly focusing on the TPU-WTR filament, presenting a novel approach to sustainable consumption and production aligned with the United Nations Sustainable Development Goal 12.

Abstract
This introductory chapter begins by outlining the background of this book: how the concept of excessive teacher entitlement took shape and was progressively enriched through my collaborative work with Cheryl J. Craig. Our ongoing informal dialogues gave rise to an invisible college where we co-created new meanings to deepen the understanding of professional inertia. We saw professional inertia as a manifestation of excessive teacher/faculty entitlement constantly adrift in a yin and yang relationship with their best-loved self. This insight came from challenging the narrow mainstream view of the notion of excessive entitlement as a purely volitional act of autonomous individuals which leads to blaming and pathologizing teachers/faculty. Instead, a Vygotskian cultural-historical perspective is proposed. This perspective facilitates a more complex historicized view of the phenomenon by directing attention to the historically and culturally mediated nature of excessive teacher/faculty entitlement and the means to alleviate it. The healing touch to excessive teacher/faculty entitlement repeatedly surfaces as humanizing pedagogy. This involves helping teachers/faculty develop empowered entitlement and work towards realizing their dreams, their best-loved self. Finally, this introductory chapter provides a brief overview of the 15 chapters that follow. They explore the notion of excessive teacher/faculty entitlement in diverse sociocultural contexts and examine promising approaches to address this problem from different theoretical and methodological angles. You are invited to join us in this rich journey of inquiry and transformation.

Abstract
This chapter investigates the experiences of doctoral students and supervisors in the doctoral process, focusing on the potential impact of imbalances in the distribution of power. In this respect, there are troublesome manifestations of excessive faculty entitlement that appear to be a source of inequality and injustice. These phenomena call into question the crucial relationship of support expected of doctoral students, as thesis supervisors have a fundamental role to play in guiding them towards the doctorate and ensuring their successful entry into the research community. Looking at the issue from the angle of the theory of social fields, I examine instances of dysfunction in supervisory experiences. Such problematic practices tend to conform to the relationships and traditions that sustain and (re)produce the practices of the academy, constraining the establishment of what Bakhtin describes as a dialogical relationship, between doctoral students and supervisors. I examine this problem from my own experience, both as a doctoral student and as a supervisor. I approach the question by combining self-study and narrative inquiry to make use of the data from my experience to analyse the issues raised during the supervision of doctoral programmes. I connect accounts drawn from literature, real-life testimonies and a corpus of discussions and notes to explore the manifestations of excessive faculty entitlement in the form of asymmetries and difficulties that can negatively impact the quality of supervision.

Abstract
This chapter presents three Chinese teachers' narrative accounts about how they live in dilemmatic spaces due to excessive entitlement. Still, the teachers move forward with transformative agency. The thick description of the three teacher participants has been reported elsewhere as the narratives of Lee – a math teacher, Ping – a Chinese language teacher and Wang – a school principal. In this chapter, however, ‘excessive teacher entitlement’ is used as a new lens to assist me in revisiting their stories of living in dilemmatic spaces. Narrative inquiry as a method unpacks the three teachers' life experiences. Although Lee, Ping and Wang encounter different entitlements and various dilemmas, their transformative agency in transitioning from a survival mode to thriving human beings brings out the similarities in their experiences. Using Vygotskian philosophy and cultural-historical activity theory (CHAT), this chapter focuses on the teachers' transformative agency as breaking away from given boundaries in their professional lives and taking up initiatives that confront the tacit excessive entitlement in and around them. Furthermore, transformative agency is promising in that it helps develop new practices in teacher education. Finally, the new understanding emanating by viewing the three subjects' experiences from the angle of excessive entitlement has the potential to inspire teachers in other contexts to become conscious of manifestations of excessive entitlement not only in themselves or others they interact with but also in the macro context we live in. This consciousness also increases the likelihood of the urge to find ways to ameliorate excessive entitlement and to move closer to one's cherished professional values.

Abstract
Purpose
A synthesis of integrated care models classified by their aims and central characteristics does not yet exist. We present a collection of five “archetypes” of integrated care, defined by their aims, to facilitate model comparison and dialogue.
Design/methodology/approach
We used a purposive literature search and expert consultation strategy to generate five archetypes. Data were extracted from included articles to describe the characteristics and defining features of integrated care models.
Findings
A total of 25 examples of integrated care models (41 papers) were included to generate five archetypes of integrated care. The five archetypes defined include: (1) whole population models, (2) life stage models, (3) disease-focused models, (4) identity group-based models and (5) equity-focused models.
Research limitations/implications
The five presented archetypes offer a conceptual framework for academics, health system decision makers and patients, families, and communities seeking to develop, adapt, investigate or evaluate models of integrated care.
Originality/value
Two cross-cutting themes were identified, including (1) minimal reporting of patient, caregiver and community engagement efforts in integrated care development, implementation and evaluation, and (2) the nuanced emphasis and implementation of electronic data sharing methods across archetypes, and the need for further definition of the role of these data sharing methods.

Abstract
Purpose
Algorithm bias refers to repetitive computer program errors that give some users more weight than others. The aim of this article is to provide a deeper insight of algorithm bias in AI-enabled ERP software customization. Although algorithmic bias in machine learning models has uneven, unfair and unjust impacts, research on it is mostly anecdotal and scattered.
Design/methodology/approach
As guided by the previous research (Akter et al., 2022), this study presents the possible design bias (model, data and method) one may experience with enterprise resource planning (ERP) software customization algorithm. This study then presents the artificial intelligence (AI) version of ERP customization algorithm using k-nearest neighbours algorithm.
Findings
This study illustrates the possible bias when the prioritized requirements customization estimation (PRCE) algorithm available in the ERP literature is executed without any AI. Then, the authors present their newly developed AI version of the PRCE algorithm that uses ML techniques. The authors then discuss its adjoining algorithmic bias with an illustration. Further, the authors also draw a roadmap for managing algorithmic bias during ERP customization in practice.
Originality/value
To the best of the authors’ knowledge, no prior research has attempted to understand the algorithmic bias that occurs during the execution of the ERP customization algorithm (with or without AI).

Abstract
As Ratnam makes clear, a cultural–historical perspective on teacher/faculty excessive entitlement is indispensable if we are to use this concept to work with, rather than undermine, education practitioners. In this chapter, a networked relational model of activity is proposed as a tool for understanding excessive entitlement from a cultural–historical activity theory (CHAT) perspective, so that the transformative potential of both entitlement and the modeling of it may be harnessed. The networked relational model, which represents CHAT activity systems as a hand-draw or painted network of relationships between actors and artifacts, allows its creators, in their capacity as researchers or academics, to use it as an imaginative artifact in the Wartofskian sense. That is, by representing activity systems of academic performance as networks of interacting entities, the emergence of excessive entitlement can be traced to, and perhaps mitigated through the relationships that they represent. In this regard, the why, what, and how artifacts proposed by Engeström are taken up as useful means for enhancing the functioning of the networked relational model not just as a tool for analyses of entitlement but also a means for envisioning alternative countercultures into being.

Abstract
In an age of educational reform which incentivises increased digitisation and standardisation, teachers are expected to embrace the rise of ‘new’ tools and pedagogies with limited agency to inform, question or direct what ‘newness’ must be brought into their classrooms. Drawing on my research with English as a Foreign Language (EFL) educators in South Africa and using an ‘excessive entitlement’ lens, I showcase how teachers' lack of agency can result in ‘defensive’ and ‘coercive’ practices in the classroom which are a far cry from the education transformation imagined according to either global and local imaginaries for teaching and learning. If we are interested in an educational revolution, I argue that a fundamental reorientation in education recognising teachers' agency in informing change is necessary. To do so requires theoretically driven intervention methodologies which view the competing demands placed on teachers as entry points to developing their agency and volition to find practices which work for them and their students in the classroom. To that end, I illustrate how Cultural-Historical Activity Theory (CHAT) informed interventions like Change Laboratories could aid in this fundamental repositioning for teachers regarding transformational efforts and their far-reaching potential for educational revolution becoming conscious of and overcoming their feelings of excessive entitlement.
