Abstract
Purpose
The purpose of this paper is to present an analytical approach to find the reduction in the required number of surface mount capacitors by the use of embedded capacitors in decoupling applications.
Design/methodology/approach
The analytical model used to perform decoupling is cavity model from theory of microstrip antenna and N‐port impedance matrix. The methodology involves addition of decoupling capacitors between the power and the ground plane such that the impedance between ports on the power‐ground plane becomes lower than the target impedance at that frequency. A case study is presented in which a 0.3 m×0.3 m power‐ground plane is decoupled by using various combinations of surface mount capacitors and embedded capacitors in the frequency range of 0.001‐1 GHz and at a target impedance of 0.1, 0.01, and 0.001 Ω. The total number of surface mount capacitors are compared in each case.
Findings
Use of embedded planar capacitors with a thin dielectric (about 8 mm) dampened board resonances at high frequency, as compared to a thick dielectric. Embedded capacitors are found to reduce the number of surface mount capacitors when the target impedance is low and the operating frequency is high.
Research limitations/implications
The methodology discusses in this paper is applicable to a simplified power‐ground plane (which has no cut‐outs and is rectangular in shape) as compared to actual digital circuits.
Originality/value
This methodology can be used as a quick preliminary tool to evaluate the decrease in the number of surface mount capacitors (by the use of embedded capacitors) as compared to complex and time consuming electromagnetic solvers.

Abstract
Groundwater resources are the primary source of meeting the water demand in Bangladesh. In rural areas, hand-pumped tube wells have been the primary source of drinking water. Though studies claim that Bangladesh has the potential to achieve universal safe drinking water supply coverage, the presence of excessive arsenic in the shallow groundwater sources, and the encroachment of salinity in the coastal aquifers in coastal regions (Satkhira, Khulna, Bagerhat, Patuakhali, Jhalakathi, Pirojpur, Barisal, Barguna etc.) hind the path. The concerned authorities of government and other non-government organizations assist the coastal people with alternative technologies like Desalination Plant, Arsenic-Iron Removal Plant, Pond Sand Filtration (PSF), Managed Aquifer Recharge, Rainwater Harvesting System, Installation of Shallow, and Deep Tube Wells. But based on case studies and surveys, this article shows how these existing technologies fail to ensure water safety within the coastal areas. The Singaporean water management policy is an example, this article advocates for necessary government intervention to ensure safe drinking water in coastal areas.

Abstract
Purpose
The purpose of this paper is to investigate the perceived thermal comfort experienced by active Muslim women (AMW) wearing hijabs determined by their experience of comfort sensation while doing sports activities or regular exercises. This study also examines whether the casual hijabs which are widely used among AMW are able to supply the appropriate comfort for active purposes.
Design/methodology/approach
This study used the quantitative method using survey questionnaires to collect 100 primary data obtained from AMW respondents who are university students located around the Klang Valley region in Malaysia.
Findings
Based on the overall results, this study suggests that the common hijabs that are used for casual applications do not offer sufficient comfort to Muslim women while performing sports activities or regular exercises.
Research limitations/implications
The outcome of this study will help to gain a better understanding on hijab preferences and comfort experienced from the viewpoint of regular hijab users. The information will assist industries to consider the selection of the right materials when developing sportswear hijabs to provide better comfort for more AMW in the near future. The method used in this study is useful to gain information on consumer’s profile and value-added details about the discomfort aspects of hijab which are scarce in the existing literature on thermal comfort.
Originality/value
This study was conducted to explore the type of hijabs commonly worn by AMW while performing sports activities and to obtain their views on the perceived thermal comfort.

Abstract
Purpose
The aim of the study is to examine the impact of the big data analytics capabilities (BDAC) on the organizational performance. The study also examines the mediating role of ambidexterity and the moderating role of business value of big data (BVBD) analytics in the relationship between the big data analytics capabilities and the organizational performance.
Design/methodology/approach
This study collected primary data based on a questionnaire survey among the large manufacturing firms operating in UAE. A total of 650 questionnaires were distributed among the manufacturing firms and 295 samples were used for final data analysis. The survey was conducted from September to November in 2019, and data were analyzed based on partial least squares structural equation modeling (PLS-SEM).
Findings
The big data analysis (BDA) scalability is supported by the findings on the performance of firm and its determinants such as system, value of business and quality of information. The roles of business value as a moderator and ambidexterity as mediator are found significant. The results reveal that there is a need for managers to consider the business value and quality dynamics as crucial strategic objectives to achieve high performance of the firm.
Research limitations/implications
The study has significant policy implication for practitioners and researchers for understanding the issues related to big data analytics.
Originality/value
This is an original study based on primary data from UAE manufacturing firms.

Abstract
The purpose of the paper is to present the result of an empirical review as to how and to what extent the interest‐free microfinance to micro entrepreneurs contributes in minimising different cots of both the lender and the borrowers. An institutional‐network theoretical approach is used to study the phenomenon. A qualitative nature of research methodology is used while studying this particular phenomenon. A multiple explanatory case study was adopted as a research strategy in order to focus on contemporary phenomenon within the real life context of different rural‐based micro entrepreneurs and their relationships with the lending organisations. Interest‐free microfinance by Islamic banks is characterised by a close supervision and an in‐kind type of financing, which contributes greatly in promoting lender‐borrower network relationships between the bank and the rural based micro entrepreneurs. Such network relationships result in minimising exchange costs and other business related costs of both the borrowers and the lending organisations. The study was mainly concerned with rural‐based micro entrepreneurs who are engaged in grass‐root type entrepreneurs like poultry and diary firm, handloom industry, etc. Particular reference is made here to the facts of rural‐based micro entrepreneurs and their relationships with Islamic banks in Bangladesh.

Abstract
Purpose
The purpose of this article is to explore the impression management practices in Covid-19 related discourses in the annual reports of the insurance companies in Bangladesh.
Design/methodology/approach
To fulfil this objective, the authors have conducted a discourse analysis of the Covid-19 related corporate narratives in the latest annual reports of listed insurance companies. The findings are then interpreted through the lens of impression management theory, following the impression management strategies identified by Caliskan et al. (2021).
Findings
It is found that companies tried to manage the impression of the stakeholders through the strategic use of language. There is evidence that the companies used assertive and performance-oriented tactics to impress their stakeholders. In few cases, defensive strategies were applied.
Practical implications
This study will facilitate improving the understanding of corporate communication during the Covid-19 crisis. Policymakers will be able to understand the current status of Covid-19 related disclosures and consider the necessity to provide guidance that may lead to better accountability during the crisis.
Originality/value
This study will contribute to the limited literature on Covid-19 related disclosure from the context of developing economies. This research is methodologically novel as it applies discourse analysis and interprets the findings through the lens of impression management.

Abstract
Purpose
The recent development in integrated reporting (<IR>) demonstrated a potential government tool for decision-making in allocating resources and developing sustainable policies for higher education institutions. This paper aims to examine the extent of the disclosure level of <IR> content elements in the annual reports of Malaysian Public Universities (MPUs). Additionally, the relationship between the disclosure level of <IR> content elements and the specific characteristics of MPUs is investigated.
Design/methodology/approach
The study performed descriptive statistics analysis for each component of <IR> content elements. This idea is achieved by examining the annual reports of MPUs between 2016 and 2018. The relationship was also investigated using ordinary least squares, fixed effect and lagged models.
Findings
The findings showed an increasing trend in the disclosure level of <IR> content elements in MPUs’ annual reports, supported by institutional theory. Furthermore, RUs exhibited a significant positive relationship with the disclosure level of <IR> content elements, whereas university size and report conciseness are insignificant variables.
Originality/value
The study adds to the body of knowledge in public sector accounting and has significant implications in the industry. This implication is specific to achieving sustainable development goals within the context of a developing country, paving avenues for further MPU reporting studies.

The purpose of this study is to explore the gender-related discourses in the annual reports of the listed companies in Bangladesh.
Abstract
Purpose
The purpose of this study is to explore the gender-related discourses in the annual reports of the listed companies in Bangladesh.
Design/methodology/approach
To fulfill this objective, a sociological discourse analysis (SDA) of the gender-related texts in the annual reports of Bangladeshi companies (listed in the Dhaka Stock Exchange) was conducted. Sandberg and Holmlund’s (2015) organizational impression management tactics (description, praise, admission, defense and writing styles) was applied as the analytical framework of SDA. The findings of the study were interpreted from a triangulation of two different theories: legitimacy theory and impression management theory.
Findings
The study suggests that the companies in Bangladesh are disclosing gender-related information to a limited extent. They provide some information in relation to equal opportunities, business activities targeted to women and corporate contribution to women’s welfare. Most of these gender-related discourses are rhetorical in nature. The companies used various impression management tactics such as description, praise, positive writing style, vague writing style and emotional writing style.
Research limitations/implications
This study is exploratory in nature and focuses on cross-sectional data. Thus, it does not identify the trend of corporate gender reporting over the years.
Practical implications
At the policy level, the findings revealed a need for reporting guidelines for gender narratives. Although there is a global gender reporting guideline as proposed under global reporting initiative, there is no local guideline in Bangladesh. Our findings suggest that in the absence of proper directives, companies presented facts and figures rhetorically and qualitatively.
Social implications
Our findings provide valuable insights for the companies in assisting the Government of Bangladesh to deal with the prevailing gender inequality and achieved gender-related sustainable development goals. It is argued that the government should take more interest in corporate social responsibility activities (such as promoting gender equality) and introduce legislation and guidelines for social accounting.
Originality/value
This is one of the very few studies that illustrate the corporate gender reporting of a developing economy – Bangladesh. To make a unique contribution to corporate gender disclosure, the study has drawn its analysis from a triangulation of the impression management and the legitimacy perspectives. Also, the use of SDA for annual report analysis has informed the readers about “how” the corporate narratives are presented in the annual reports rather than “what” issues are disclosed as commonly done in content analysis.

Abstract
Purpose
The purpose of the paper is to examine the influence of consumers' perceived knowledge, knowledge discrepancy and confusion on the intention to purchase farmed fish (FF) via a survey design regarding perceptions, buying and consumption practices of urban households in Chittagong, Bangladesh.
Design/methodology/approach
The samples of 498 households were selected from a stratified cluster from the Chittagong city and were interviewed using a structured questionnaire. The data have been analysed using exploratory factor analysis and structural equation modelling.
Findings
The results show that consumers' subjective knowledge (SK) is significant for purchase intention whereas objective knowledge (OK) is not. Again, consumers' SK, OK, knowledge discrepancy and confusion have no influence in forming consumers' attitude towards FF. However, consumers who overestimate their actual level of knowledge hold negative attitude towards FF and vice versa. Furthermore, consumers' OK affects their confusion inversely although it does not influence the purchase intention significantly.
Practical implications
If the marketers can frame a more engaging means of communication and knowledge enhancement plan, consumers' attitude and purchase intention regarding FF will be signified.
Originality/value
This is the first study that fundamentally contributes to the scientific research in that it measures the knowledge discrepancy of consumers regarding FF. In addition, this study substantiates that low objective knowledge leads to confusing consumers at the time of purchasing. The effect of overestimating the level of knowledge as well as underestimating the level of knowledge in explaining the purchase intention of FF would be a supplementary addition.
