To explore how Critical Management Studies can be used to frame a strategy to effect change and promote diversity and inclusion in organizations.
Abstract
Purpose
To explore how Critical Management Studies can be used to frame a strategy to effect change and promote diversity and inclusion in organizations.
Design/methodology/approach
Drawing on the experience gained from a large multi-sector action research project aimed at promoting equality, diversity and inclusion in organizations, this chapter proposes a multilayer [Critical] Ecological Model.
Findings
While early critical theorists were committed to effecting change, the rise of post-modern critical theory eroded the ground on which to stand, widening the gap between theory and practice. Secondly, the chapter asserts the importance of linking empirical research and critical theory in order to advance equality seeking projects. Thirdly, the chapter provides a [Critical] Ecological model that bridges theory and action in Critical Management Studies, based partly on experience from a large community-based research project. The need for a multifaceted approach to advance equality and inclusion emerged as a way to bridge ideological differences among actors and academics committed to effecting social change.
Practical implications
By addressing directly the challenges of theoretical rifts as well as differences in research focused on micro, meso and macro levels, the chapter builds a framework to allow different stakeholders – scholars, practitioners, activists and change agents across sectors – to take action in advancing inclusion and equality as well as an understanding of interactions between levels.
Originality/value
While sharing similar goals, many approaches to change are fragmented on the level of analysis and by underlying paradigms. This chapter is unique in its focus on ways to bridge theory and practice and to develop a framework for action that accommodates equality seeking theorists and activists working on several levels.

Abstract
Purpose
Die edge quality with its corresponding die strength are two important factors for excellent dicing quality especially for low-k wafers due to their weak mechanical properties and fragile structures. It is shown in past literatures that laser dicing or grooving does yield good dicing quality with the elimination of die mechanical properties. This is due to the excess heat energy that the die absorbs throughout the procedure. Within the internal structure, the mechanical properties of low-k wafers can be further enhanced by modification of the material. The purpose of this paper is to strengthen the mechanical properties of wafers through the heat-treatment process.
Design/methodology/approach
The methodology of this approach is by heat treating several low-k wafers that are scribed with different laser energy densities with different laser micromachining parameters, i.e. laser power, frequency, feed speed, defocus reading and single/multibeam setup. An Nd:YAG ultraviolet laser diode that is operating at 355 nm wavelength was used in this study. The die responses from each wafer are thoroughly visually inspected to identify any topside chipping and peeling. The laser grooving profile shape and deepest depth are analysed using a laser profiler, while the sidewalls are characterized by scanning electron microscopy (SEM) to detect cracks and voids. The mechanical strength of each wafer types then undergoes three-point bending test, and the performance data is analyzed using Weibull plot.
Findings
The result from the experiment shows that the standard wafers are most susceptible to physical defects as compared to the heat-treated wafers. There is improvement for heat-treated wafers in terms of die structural integrity and die strength performance, which revealed a 6% increase in single beam data group for wafers that is processed using high energy density laser output but remains the same for other laser grooving settings. Whereas for multibeam data group, all heat-treated wafer with different laser settings receives a slight increase at 4% in die strength.
Originality/value
Heat-treatment process can yield improved mechanical properties for laser grooved low-k wafers and thus provide better product reliability.

Abstract
Self-Service Technology (SST) is a disruptive technology that has reshaped customer interactions, increased efficiency, and enabled data-driven decision-making. Its impact continues to evolve as technology advances and customer expectations change, making it a key consideration for businesses in a dynamic landscape. This chapter delves into critical findings regarding the adoption and implications of SST in tourism and hospitality. The relevant studies are sourced from the Scopus database. A mixed literature review methodology was employed to review papers. The literature review findings show facets of SST adoption, shedding light on the intricate relationships between consumer readiness variables, context-specific influences, preferred SST features, and psychological attributes. The study reveals consumer preferences, including convenience, ease of use, and speed of service, as primary drivers of the adoption of SST. The bibliometric analysis reveals the scope for developing SST literature in tourism and hospitality. Collaborations among scholars, research and funding institutions could help provide the impetus. Research in SST security, sustainability, and resilience could help enhance the SST literature. Comparative studies evaluating SST's social and economic implications are also suggested.

The objective of this study is to examine the dose‐response effect of inulin on mineral absorption and faecal short‐chain fatty acids concentration in formula‐fed infants.
Abstract
Purpose
The objective of this study is to examine the dose‐response effect of inulin on mineral absorption and faecal short‐chain fatty acids concentration in formula‐fed infants.
Design/methodology/approach
The effects of inulin on faecal short‐chain fatty acids and minerals absorption in 36 healthy, formula‐fed infants given three different doses of inulin (0.75g/d, 1.00g/d, and 1.25g/d) were studied using complete randomized design. Acetic, butyric, propionic and lactic acids were analysed using gas chromatography.
Findings
No significant (p<0.05) difference was observed in the infant faecal short‐chain fatty acids contents during the basal period, the intake period and the washout period. A significant (p<0.05) increase in per cent apparent absorption, per cent apparent retention and net retention of iron were seen in infants supplemented with 1g/day inulin. A significant (p<0.05) increase in per cent apparent retention and net retention of Magnesium was also seen in infants supplemented with 0.75, 1 and 1.25g/day inulin. A significant (p<0.05) increase in per cent apparent absorption and net retention of Zinc was seen in infants supplemented with only 0.75g/day inulin. No significant improvement in calcium, or copper absorption or retention was observed in all the doses of inulin studied.
Originality/value
Most previous studies were conducted on adults and adolescents.

Abstract
Purpose
This paper aims to deal with the optimization of engine operational parameters such as load, compression ratio and blend percentage of fuel using a combined approach of particle swarm optimization (PSO) with Derringer’s desirability.
Design/methodology/approach
The performance parameters such as brake thermal efficiency (BTHE), brake specific fuel consumption (BSFC), CO, HC, NOx and smoke are considered as objectives with compression ratio, blend percentage and load as input factors. Optimization is carried out by using PSO coupled with the desirability approach.
Findings
From results, the optimum operating conditions are found to be at compression ratio of 18.5 per cent of fuel blend and 11 kg of load. At this input’s parameters of the engine, outputs performance parameters are found to be 34.84 per cent of BTHE, 0.29 kg/kWh of BSFC, 2.86 per cent of CO, 13 ppm of HC, 490 ppm of NOx and 26.25 per cent of smoke.
Originality/value
The present study explores the abilities of both particle swarm algorithm and desirability approach when used together. The combined approach resulted in faster convergence and better prediction capability. The present approach predicted performance characteristics of the variable compression ratio engine with less than 10 per cent error.

Abstract
Purpose
The purpose of this paper is to explore the variety of food in which it has been applied as a prebiotic and functional ingredient, the concentrations used there in, the tests that have been conducted on these fortified foods and briefly reviews the history and characteristics of inulin.
Design/methodology/approach
The review included articles from 1999-2013. The papers which reported inulin concentrations used, the purpose of the application and tests on final product, were mainly selected. Articles were collected in electronic databases such as Elsevier-Science Direct, Emerald, Springer Link, Wiley and Redalyc.
Findings
The interaction inulin-food with different food matrices is complex, and is not always technologically favorable for the product. Moreover, additional to evaluations of sensory, physicochemical and rheological characteristics, it is essential to carry out measurements in the food, of such characteristics as prebiotic content, and prebiotic activity in vivo and in vitro, and assess potential adverse reactions in order to define suitable doses of consumption.
Originality/value
The paper highlights the importance of conducting in vitro and in vivo testing of potential prebiotic inulin-supplemented food in order to define dose that benefit health and do not cause unacceptable gastrointestinal distress.

Abstract
This study evaluates low Reynolds number models of turbulence for numerical computations on the heat transfer and fluid flow behavior in a rectangular channel with streamwise‐periodic ribs mounted on one of the principal walls. The models include k − ε models of Launder and Sharma (1974), Chien (1982), k − ε model of Lin and Hwang (1998), Wilcox’s k−ω model (Wilcox, 1994) and Durbin’s model k − ε −v2 (Durbin, 1995). The numerical results show that all these models can predict the flowfield reasonably well, and the inclusion of the Yap term (Yap, 1987) in the ε – equation (or ε – equation) can further improve the prediction in these k − ε models, k − ε model and k − ε − v2 model. However, these models behave differently in heat transfer computations. The k − ω model leads to too low a level of heat transfer and turbulence. Among these k − ε models and the k − ε model, Lin’s model with the Yap term predicts the heat transfer level best. Durbin’s model with extra v2, f equations and the Yap term exhibits further improvement.

Abstract
Purpose
The success rate of Lean Six Sigma (LSS) in the service industries is dismally poor, and most organisations discontinue LSS initiatives prematurely. This paper aims to identify the LSS barriers (LSSBs) and analyse their interaction via a hierarchical model developed by using interpretive structural modelling (ISM) and Fuzzy Matriced Impacts Croise’s Multiplication Appliqué à un Classement (MICMAC). These allow the LSS execution and implementation to be much more effective and avoid the high cost of implementation.
Design/methodology/approach
A structural review of the literature and interviews with experts and professionals from the service industries in the UAE supplied data wherewith to identify LSSBs. Sixteen LSSBs were determined and analysed using ISM and the MICMAC approach to discover the strong drivers and highly dependent barriers. The Fuzzy set was included in the MICMAC analysis to obtain a more precise output and create an effective hierarchical model of the barriers.
Findings
The research findings suggest that the top barriers to LSS implementation in service industries are lack of top management commitment, lack of customer focus, resistance to change management and lack of alignment between the LSS and organisational strategy. A deeper analysis using the Fuzzy-MICMAC approach categorises these barriers on the basis of their driving power and dependency.
Research limitations/implications
The relationships between paired LSSBs were obtained through an experts’ interpretations of limited numbers in one country. Conducting a large-scale survey with a more comprehensive demographic or deep focus in one service industry might deepen our understanding of the interactions of LSSBs and models.
Practical implications
The developed ISM that model suggests that the dependencies and relationships among the barriers must be accurately determined so as to remove the collaborative effect of barriers on the implementation process is at the earliest opportunity. This would improve service companies’ competitive advantage and profitability, drive out waste and reduce the cost associated with poor quality. Similarly, academicians may advocate ways in various issues can contribute to improve LSSBs for amended LSS implementation now that business services are booming in the fourth industrial revolution.
Originality/value
The structural model was developed holistically on the basis of the inputs from practitioners and academicians to ensure its practical validity. Though the model has theoretical foundations, its practical applicability is a key factor in its development, so this approach was helpful for practitioner wanted to focus on removing the key dominant barriers and be able to deploy LSS concepts smoothly in service industries. The results support the proposition that top management is a crucial factor for LSS project implementation, whatever the complexity of the research methodology and the nature of the service industries.

Abstract
Purpose
The purpose of this study is to highlight key issues pertaining to making use of Islamic equity indices and proposing possible solutions to address the problems faced in advancement of the concept of Shariah investing (SI) with the aim to advance the discourse on the subject.
Design/methodology/approach
Online focus group discussion (FGD) was carried out in which ten Islamic finance researchers and analysts belonging to institutions considered as authority on the subject matter participated to share their viewpoints on Islamic equity indices. Content analysis on the collected data of FGD was carried out which has revealed six key themes.
Findings
Six broader themes were identified based on the analysis of FGD, which includes criteria for constructing Islamic equity indices, utilization of Islamic equity indices for comparison with conventional stock indices, stock market efficiency perspectives, reason for integration of different equity markets, investors’ awareness of SI and future directions of Islamic equity indices. Results of the study indicate that Islamic finance researchers and analysts opined that there is a need for revising the criteria for construction of Islamic equity indices. There are conflicting viewpoints regarding performance and efficiency of Islamic indices in comparison with conventional indices and main reasons for stock market integration are trade liberalization, globalization and other factors. Moreover, there is a need for making investors and other market players aware about the attractiveness of Islamic indices from investing point of view.
Originality/value
Based on this extensive literature review and as highlighted by Masih et al. (2018) in their recap of literature on Islamic equity indices indicating that there are bulk of empirical studies carried in the past in the domain, however, there is a dearth of theoretical and qualitative studies. Hence, this preliminary qualitative study not only makes theoretical contribution but also deploys FGD, which is rarely used in the similar context, and offers candid views of the participants on key issues pertaining to Islamic equity indices. This lends novelty to this study.

Abstract
Information and communications technology (ICT) offers enormous opportunities for individuals, businesses and society. The application of ICT is equally important to economic and non-economic activities. Researchers have increasingly focused on the adoption and use of ICT by small and medium enterprises (SMEs) as the economic development of a country is largely dependent on them. Following the success of ICT utilisation in SMEs in developed countries, many developing countries are looking to utilise the potential of the technology to develop SMEs. Past studies have shown that the contribution of ICT to the performance of SMEs is not clear and certain. Thus, it is crucial to determine the effectiveness of ICT in generating firm performance since this has implications for SMEs’ expenditure on the technology. This research examines the diffusion of ICT among SMEs with respect to the typical stages from innovation adoption to post-adoption, by analysing the actual usage of ICT and value creation. The mediating effects of integration and utilisation on SME performance are also studied. Grounded in the innovation diffusion literature, institutional theory and resource-based theory, this study has developed a comprehensive integrated research model focused on the research objectives. Following a positivist research paradigm, this study employs a mixed-method research approach. A preliminary conceptual framework is developed through an extensive literature review and is refined by results from an in-depth field study. During the field study, a total of 11 SME owners or decision-makers were interviewed. The recorded interviews were transcribed and analysed using NVivo 10 to refine the model to develop the research hypotheses. The final research model is composed of 30 first-order and five higher-order constructs which involve both reflective and formative measures. Partial least squares-based structural equation modelling (PLS-SEM) is employed to test the theoretical model with a cross-sectional data set of 282 SMEs in Bangladesh. Survey data were collected using a structured questionnaire issued to SMEs selected by applying a stratified random sampling technique. The structural equation modelling utilises a two-step procedure of data analysis. Prior to estimating the structural model, the measurement model is examined for construct validity of the study variables (i.e. convergent and discriminant validity).
The estimates show cognitive evaluation as an important antecedent for expectation which is shaped primarily by the entrepreneurs’ beliefs (perception) and also influenced by the owners’ innovativeness and culture. Culture further influences expectation. The study finds that facilitating condition, environmental pressure and country readiness are important antecedents of expectation and ICT use. The results also reveal that integration and the degree of ICT utilisation significantly affect SMEs’ performance. Surprisingly, the findings do not reveal any significant impact of ICT usage on performance which apparently suggests the possibility of the ICT productivity paradox. However, the analysis finally proves the non-existence of the paradox by demonstrating the mediating role of ICT integration and degree of utilisation explain the influence of information technology (IT) usage on firm performance which is consistent with the resource-based theory. The results suggest that the use of ICT can enhance SMEs’ performance if the technology is integrated and properly utilised. SME owners or managers, interested stakeholders and policy makers may follow the study’s outcomes and focus on ICT integration and degree of utilisation with a view to attaining superior organisational performance.
This study urges concerned business enterprises and government to look at the environmental and cultural factors with a view to achieving ICT usage success in terms of enhanced firm performance. In particular, improving organisational practices and procedures by eliminating the traditional power distance inside organisations and implementing necessary rules and regulations are important actions for managing environmental and cultural uncertainties. The application of a Bengali user interface may help to ensure the productivity of ICT use by SMEs in Bangladesh. Establishing a favourable national technology infrastructure and legal environment may contribute positively to improving the overall situation. This study also suggests some changes and modifications in the country’s existing policies and strategies. The government and policy makers should undertake mass promotional programs to disseminate information about the various uses of computers and their contribution in developing better organisational performance. Organising specialised training programs for SME capacity building may succeed in attaining the motivation for SMEs to use ICT. Ensuring easy access to the technology by providing loans, grants and subsidies is important. Various stakeholders, partners and related organisations should come forward to support government policies and priorities in order to ensure the productive use of ICT among SMEs which finally will help to foster Bangladesh’s economic development.
