Abstract
Purpose
The study aims at providing a reliable system of real-time monitoring for underground mine and tunnels which detects any structural change in the network and reconfigures it for resuming the data delivery process. In high stress environments, e.g. underground mines and tunnels, real-time activity monitoring is an emerging issue. Wireless sensor networks (WSNs) play a key role in ensuring the safety of people working in underground mines and tunnels. WSN not only provide real-time monitoring of underground environment but also detects any structural change in the network itself.
Design/methodology/approach
In this paper, results of empirical implementation of a re-configurable WSN, capable of self-healing approach, reconfigure the network connectivity upon failure or addition of nodes in the system. An open-source radio-frequency identification standard for WSN, named as DASH7, is used for practical implementation. The proposed system is capable of determining cluster breakage by sudden disruptions caused by roof falls, explosions and node failures, sensor coverage hole, node re-addition to the network and distress priority signal generation by the miner.
Findings
The proposed platform contributes to re-attain network state for establishing a communication link with fusion center in terms of: instant and accurate detection of collapse holes, acceptable error rate, time to re-attain network state, rapid distress signal propagation and low deployment cost. This platform is deployed in four different environments of anechoic chamber, hallway, outdoor and underground mine environment, to test the aforementioned scenarios using DASH7-compatible Bitsense Sensor Motes operating at 433 MHz. The effectiveness of the proposed approach has been experimentally validated for the single and multiple adjacent and disjoint node failures in all the four environments.
Originality/value
The number of monitoring systems was implemented for safety assurance in high stress environments before, but the novelty of our platform is long range, cost effectiveness, quick response to any structural change in the network, rapid and accurate data delivery using WSN operated on DASH7 protocol stack.

Abstract
Purpose
This case captures the experience of the newly hired investigation officer (IO) at the SECP, who crafts a front running case focused on the ethical transgressions by equity trader and KATS operator, at a famous brokerage house named Mir Ali Chaudhary Securities (MAC) Securities and three traders at DICE in Pakistan. The case outlines the whole series of investigation event that took place, from the IO identifying the smoke to all the pieces of puzzle together to form collectively evidence of front running. The case outlines and probes students to think at each stage of investigation as to how to answer the general claims that insider trading should be legalized. All these questions are viewed from the perspective of Pakistan’s regulatory environment.
Design/methodology/approach
The authors use a descriptive case study methodology approach.
Findings
The investigation trial held Sidney and Aslam guilty, sentencing them to imprisonment and making them pay fine to the Securities Exchange Commission of Pakistan (SECP) worth Rs 5m and Rs 1m, respectively. Likewise, the three equity traders at DICE were sentenced to imprisonment and charged a fine of Rs. 1m each.
Originality/value
On March 21, 2018, Mr Sidney, the equity trader, Mr Aslam, a KATS operator at MAC Securities and three equity traders at DICE Securities (Pvt.) Ltd were convicted under Securities Act (2015) and Court of law. Sidney and Aslam were alleged of tipping off advance confidential information of their clients’ order to the three equity traders at DICE, whereas the three traders at DICE were alleged of trading shares based on the tipped information in their trading account before the MAC clients’ orders were filled.

This paper examines the impact of Russian invasion of Ukraine on the intraday efficiency of four major energy markets, namely, diesel oil, Brent oil, light oil and natural gas.
Abstract
Purpose
This paper examines the impact of Russian invasion of Ukraine on the intraday efficiency of four major energy markets, namely, diesel oil, Brent oil, light oil and natural gas.
Design/methodology/approach
This study applies the multifractal detrended fluctuation analysis (MFDFA) to high-frequency returns (30-min intervals) for the period from October 21, 2021, to May 20, 2022. The data sample of 5,141 observations is divided into two sub-samples, before and after the invasion of 24th February 2022. Additionally, the magnitude of long memory index is employed to investigate the presence of herding behavior around the invasion period.
Findings
Results confirm the presence of multifractality in energy markets and reveal significant changes of multifractal strength due to the invasion, indicating a decline of intraday efficiency for oil markets. Surprisingly, the natural gas market, being the least efficient before the invasion, turns out to be more efficient after the invasion. The findings also suggest that investors in these energy markets are likely to show herding, more prominently after the invasion.
Practical implications
The multifractal patterns, in particular the long memory property of energy markets, can help investors develop profitable investment strategies. Furthermore, the improved efficiency observed in the natural gas market, after the invasion, highlights its unique traits and underlying complexity.
Originality/value
This study is the first attempt to assess the impact of the Russia–Ukraine war on the efficiency of global commodity markets. This is quite important because the adverse effects of the war on financial markets may potentially cause destabilizing outcomes and negative effects on social welfare on a global scale.

Abstract
Purpose
This study aimed to test some dynamics related to YouTube advertising clutter and viewers' attitudes towards YouTube channels operated by traditional television (TV) companies (These YouTube channels tend to have a greater ad clutter since their videos have embedded ads of programme sponsors in addition to regular YouTube advertisements).
Design/methodology/approach
Employing a positivistic, quantitative methodology, the study collected data through an online survey from a sample of 295 YouTube viewers in Sri Lanka. Data were analysed using the regression-based PROCESS macro, utilising the SPSS software.
Findings
Ad clutter has a negative impact on viewers' attitudes towards the YouTube channel, but only indirectly, through irritation. Skippability of advertisements does not moderate the relationship between ad clutter and ad irritation, but non-skippability increases ad irritation (direct relationship).
Practical implications
YouTube channel owners should pay careful attention to having an optimum level of advertising because clutter resulting in high ad irritation leading to a negative attitude towards the channel could reduce subscriptions. Offering an ad skippability option is unlikely to reduce irritation if there is high clutter.
Originality/value
Although ad clutter is well-researched, its impact on viewer responses to online media channels is uncommon. With YouTube poised to become a top ad revenue-generating medium, this study contributes by examining some dynamics related to ad clutter in a possibly high-clutter context.

Abstract
Purpose
The purpose of this study is to explore the key challenges of academic libraries in times of changing nature of higher education system and how library leaders can manage the challenges when effective leadership is highly required for academic libraries today. As the time is changing, the kinds of challenges that library leaders face have also changed. Author of this study explores the methods and approaches, which are more effective ways of managing challenges in the reshaping environment of academic libraries. At the same time, change has become a permanent part of academic libraries and they need leaders who are able to lead and manage change efficiently, bring theories into practices, find innovative solutions to challenges, creative thinkers, effective communicators, collaborative mindset and self-motivators.
Design/methodology/approach
The selective publications have been reviewed to find the best ways to leading changes and managing challenges in academic libraries. The approaches and methods in this study are based on personal experiences of author as director of the university libraries and experiences of library leadership worldwide are conversed.
Findings
Academic libraries are facing similar challenges around the world. The author found that academic library leadership needs innovative skills and competencies, effective communication abilities and a new way of thinking to deal with challenges and create willingness to adapt the changes. Kotter’s leadership manage change model may apply for creating and implementing organizational change in academic libraries.
Originality/value
Literature on this topic is comparatively limited. Consequently, this manuscript adds value to the publications of library and information sciences and offers the literature in the field of leadership challenges and manage change in the academic libraries. It also provides guidelines to academic library leadership universally, and how can leaders work with change effectively.

Abstract
Purpose
Though microfinance has been working for many years as a tool to eradicate poverty from its root, most of the least developed and developing countries are yet to significantly alleviate it from the society. The purpose of this paper is to focus on Shariah-based microfinance products in the context of sustainable poverty alleviation approach and provide them financial benefits to enhance their livelihoods.
Design/methodology/approach
Here, this qualitative study critically analyzes the basics of the sustainable Islamic microfinance to exterminate the level of poverty.
Findings
Islamic microfinance is a more ethical practice than the traditional motives of profit maximization, and it encourages extending the time of repayment if the debtors are in hardship. In some case, it suggests to give charity if the creditor has capability.
Research limitations/implications
Most importantly, research scholars and experts have already criticized the concept of conventional microfinance on the basis of various points, especially for its high rate of interest.
Social implications
Islamic microfinance is provided with a view to fulfill two tools simultaneously, i.e., social and financial inclusion. In this case, credits and Zakah can be given to the extreme poor people for satisfying basic needs. In terms of social responsibility, Islam encourages the people to be soft in case of collecting the lending money.
Originality/value
The study discoursed that sustainable Islamic Microfinance (IM) may be a promising future option to draw the attention of the religiously sensitive people toward the Shariah-based microfinance which can, in turn, mitigate the poverty level.

Abstract
Purpose
This paper aims to investigate the subject matter of Islamic economics that will be the object of a study as a discipline by classifying and unifying different approaches proposed by Islamic economists.
Design/methodology/approach
The paper is a conceptual paper using discursive analysis analysing the perspective and approaches proposed by Islamic economists in defining economic problems from an Islamic perspective. The perspective and approaches proposed are classified and analysed for their implications in constructing the subject matter of discipline.
Findings
Islamic economics, as a new body of knowledge, needs to clarify the economic problems that will be its subject matter. The paper brings an insight into the subject matter of Islamic economics as conceived by scholars in two approaches, namely, economic problems “as they are” and economic problems “as they should be”. The paper also proposes a unified perspective in defining the subject matter of Islamic economics for further development of the discipline.
Research limitations/implications
This paper only provides philosophical guidance for researchers in mapping the problems and the goals of the policy being studied, although it does not offer any practical use for policymaking as each policy is faced with different and specific cases. This paper may be used to assist future researchers in shaping other unexplored fields in Islamic economics as a body of knowledge.
Practical implications
Islamic economics as a discipline will be strengthened if it has a clear subject matter that will be the object of study. However, the conception of economic problems proposed by Islamic economists is based on life-reality, i.e. of what human beings face in their life (practical-type economic problems as they are) and based on life guidance from the Qur’an on how human beings should live as well as life-objectives, i.e. of what goals he should strive for (ideal-type economic problems as they ought to be) brings implication that there are differences in determining the object of study of Islamic economics.
Originality/value
This paper promotes the unification of two conceptions of economic problems proposed by scholars by defining Islamic economics as “a study of resource appropriation to realize human well-being (maslahah)”. This suggests that economic problems as manifested in life reality will be studied within the grand objective of life in Islam (maqasid al-Shariah), and economic problems as perceived in life goals will be studied in the context of life reality. Islamic economic theory will be formulated not only to solve the apparent problem of “what is” but also formulated in a way that refers to goals (ideals) of “what ought to be” that will provide solutions to current economic problems according to certain vision and to take steps to move in that visionary direction.

Abstract
Purpose
Today, the sustainability and outreach of microfinance institutions (MFIs) are crucial to the success of microfinance and the sector’s potential to make a lasting impact. The ability of MFIs to operate financially well without sacrificing their social goals has come under scrutiny. This study aims to identify the kind of relationships between the two objectives of MFIs in Ethiopia.
Design/methodology/approach
This study investigated the association between the outreach and financial sustainability of Ethiopian MFIs from the years 2012 to 2021 using a balanced set of panel data. The study used secondary data and employed a descriptive research design and a quantitative research approach. To this end, random and fixed effects estimation models, as well as three-stage least squares, with the model of seemingly unrelated regression (SUR) are used.
Findings
According to the study, outreach performance enables MFIs to achieve sustainability/financial performance. On the other side, MFI that are financially sound improve social performance. There was therefore no trade-off between the two objectives.
Originality/value
As Ethiopia’s microfinance sector shifts away from government and non-government backing and toward commercialization, such research is crucial. This aspect of the Ethiopian microfinance industry has gotten little consideration in research. The SUR model was used in the study together with random and fixed effect estimators, and the most reliable estimation result was chosen based on the necessary tests.

Abstract
Purpose
The purpose of the paper is to review and analyse different glass ceiling studies conducted in different Asian countries during the three decades after the introduction of the metaphor. It also describes the antecedents and the consequences of the glass ceiling.
Design/methodology/approach
The method chosen for the study was a computerised search of available materials using the keywords relating to glass ceiling in Asia and latest reports from international organisations.
Findings
The perception of glass ceiling existence in Asian countries has been sorted out region-wise. Different factors for glass ceiling have been categorised under different theories.
Research limitations/implications
The study includes a multiregional aspect of glass ceiling, which will be useful for further studies in this area. The limitation of the study is that it did not assess the awareness and influence of glass ceiling in each industry.
Practical implications
Since the study showed glass ceiling practices in different countries in Asia, it might help policy makers for making proper decisions for breaking of glass ceiling.
Social implications
The study may be a part of empowering women as it analyses areas of inequality and finds out antecedents.
Originality/value
This paper is the first to shed light on glass ceiling on a multicultural and multiregional aspect.

Abstract
Purpose
The purpose of this paper is to discover the main reasons for change, why change is necessary and how library professionals can adapt to change. Academic institutions are rapidly changing around the world where libraries are facing similar challenges and adapting change is a demand for growth and improvement. Library administrators need a clear vision and strategic plan to meet the upcoming challenges, they must have self-confidence, ability to work with diversity. Library professionals need to show flexibility and a willingness to develop new skills, they also need to adopt new ways of working and dealing with the academic community.
Design/methodology/approach
The literature review is built on resources from offline and online full-text databases such as ProQuest, EBSCO, Emerald, Library Literature and Information Science databases. This paper is based on a systematic literature review method which includes 50 research articles and 5 print books. A total of 109 articles were collected at the beginning stage but after their analysis in detail, they were reduced to 50 articles as the rest of the articles did not exactly focus on adapting to change in academic libraries. Basic keyword and advanced searching options have been used to retrieve the relevant literature on the topic from peer-reviewed and scholarly resources.
Findings
Changes are the result of organizational restructuring, user expectations and accessibility to a growing range of digital content, so library professionals are under pressure to adopt change in academic libraries and introduce new services and technology. Library professionals need to change traditional ways of working and boost their knowledge and skills, collaborative attitude, redesign and policies and procedures and create a willingness to adapt to the change. Challenges can be managed if an individual has a keen interest and eagerness to keep up to date with the current knowledge and emerging trends in academic libraries.
Research limitations/implications
Appropriate literature on the topic was reviewed systematically, not all publications were included. Literature on this topic is relatively limited so more research and publications are needed to deal with current and future scenarios of academic libraries.
Practical implications
This paper offers a useful overview of the ways and approaches used to adopting change by library professionals and the approaches that can be used in the current and future settings of academic libraries. Suggestions and recommendations can be used in the field of LIS, as well as library professionals may apply in the academic and research libraries to effectively change.
Originality/value
This paper focuses on the concept of adapting to change in academic libraries, rather than responding to change. This piece of opinion contributes to library science in the area of how to manage and implement change, suggests ways and frameworks which can be used to adopting change by library professionals.
