Abstract

Purpose

This study aims to determine direct and indirect ways of strengthening consumer’s halal buying behaviour. For this, the researchers explore the role of religiosity and consumers’ personal norms on consumers’ attitudes and halal buying behaviour. The study also reconnoiters the mediating role of consumer attitudes.

Design/methodology/approach

With a structured questionnaire, a survey was conducted to collect data on consumer attitudes, personal norms and halal buying behaviour. Finally, 229 valid questioners were retained for data analysis. The structural equation modelling technique was used for data analysis using SmartPLS 3.0 software.

Findings

The result of this study suggests that consumers’ attitude towards halal purchase depends on consumers’ personal norms and religiosity. Further, the role of consumer attitudes and religiosity on the halal buying behaviour of consumers is significant. However, the personal norm is not a significant predictor of halal buying behaviour. Consumer attitudes mediate the relationships between personal norms and halal buying behaviour, as well as religiosity and halal buying behaviour.

Research limitations/implications

The findings of the present study indicate that consumers’ personal norms and religiosity are the important determinants of consumer attitude and behaviour towards halal purchase. Marketers of halal products and services should focus on strengthening consumers’ attitudes and religiosity to influence consumer behaviour towards halal purchase.

Originality/value

In light of recent research studies on the halal purchase, the present research finds the essential predictors of consumers’ halal purchase attitude and behaviour. The study also reveals that consumer attitude is an important role in strengthening halal buying behaviour, as it has both direct and indirect impact halal buying behaviour.

Abstract

Purpose

This paper aims to investigate the impact of selected macro-economic variables like real effective exchange rate (REER), GDP, inflation (INF), the volume of trade (TR) and money supply (M2) on-budget deficit (BD) in Bangladesh over the period of 1980–2018.

Design/methodology/approach

By using secondary data, the paper uses the Vector Error Correction Model (VECM) and Granger Causality test. Johansen’s cointegration test is used to examine the long-run relationship among the variables under study.

Findings

Johansen’s cointegration test result shows that there exists a positive long-run relationship of selected macroeconomic variables (real effective exchange rate, inflation, the volume of trade and money supply) with the budget deficit, whereas GDP has a negative one. The short-run results from the VECM show that GDP, inflation and money supply have a negative relationship with the budget deficit. The Granger Causality test results reveal unidirectional causal relationships running from BD to REER; TR to BD; M2 to BD; GDP to REER; M2 to REER; INF to GDP; GDP to TR; M2 to GDP and bidirectional causal relationship between GDP and BD; TR and REER; M2 and TR.

Originality/value

Bangladesh has been experiencing a budget deficit since 1972 due to a decline in sources of revenue. This study contributes to the empirical debate on the causal nexus between macroeconomic variables and budget deficits by employing VECM and Granger Causality approaches.

This study aims to use an environomics method to assess the environmental impacts of selected gas turbine power plants in Nigeria.

Abstract

Purpose

This study aims to use an environomics method to assess the environmental impacts of selected gas turbine power plants in Nigeria.

Design/methodology/approach

In this study, exergoenvironomic analysis has been carried out to investigate the environmental impact of selected gas turbine power plants in Nigeria from an exergetic point of view.

Findings

The exergy analysis reveals that the combustion chamber is the most exergy destructive component compared to other cycle components. The exergy destruction of this component can be reduced by increasing gas turbine inlet temperature (GTIT). The results of the study show that thermodynamic inefficiency is responsible for the environmental impact associated with gas turbine components. The study further shows that CO2 emissions and cost of environmental impact decrease with increasing GTIT.

Originality/value

The exergo-environomic parameters computed in this study are CO2 emission in kg per MWh of electricity generated, depletion number, sustainability index, cost flow rate of environmental impacts (Ċenv) in $/h and total cost rates of products (ĊTot) in $/hr. For the period considered, the CO2 emissions for the selected plants vary from 100.18 to 408.78 kgCO2/MWhm, while cost flow rate of environmental impacts varies from $40.18 /h to $276.97 /h and the total cost rates of products vary from $2935.69/h to $12,232.84/h. The depletion number and sustainability index vary from 0.69 to 0.84 and 1.20 to 1.44, respectively.

Abstract

In this study, exergoeconomic analysis and performance evaluation of selected gas turbine power plants in Nigeria were carried out. The study was conducted using operating data obtained from the power plants to determine the exergy efficiency, exergy destruction, unit cost of electricity and cost of exergy destruction of the major components of a gas turbine engine in the selected power plants. The results of exergy analysis confirmed that the combustion chamber is the most exergy destructive component compared to other cycle components as expected. The total efficiency defects and overall exergetic efficiency of the selected power plants vary from 38.64 to 69.33% and 15.66 to 30.72% respectively. The exergy analysis further shows that the exergy improvement potential of the selected plants varies from 54.04 MW to 159.88 MW. The component with the highest exergy improvement potential is the combustion chamber and its value varies from 30.21 MW to 88.86 MW. The results of exergoeconomic analysis show that the combustion chamber has the greatest cost of exergy destruction compared to other components. Increasing the gas turbine inlet temperature (GTIT), both the exergy destruction and the cost of exergy destruction of this component were found to decrease. The results of this study revealed that an increase in the GTIT of about 200 K can lead to a reduction of about 29% in the cost of exergy destruction. From exergy costing analysis, the unit cost of electricity produced in the selected power plants varies from cents 1.99 /kWh (N3.16 /kWh) to cents 5.65 /kWh (N8.98 /kWh).

Abstract

Purpose

The purpose of this paper is to provide a better understanding about sources of water for the urban poor in Rajshahi city, Bangladesh. It evaluates water supply performances to identify priority areas of water supply for further improvement. The paper also illustrates whether location of slums in the city has a connection with water supply facilities or not.

Design/methodology/approach

The paper presents a case study of water supply for the urban slum dwellers. Based on a questionnaire survey, it evaluates performances of water supply following a holistic framework for assessing dimensions of water supply system among three slum zones of Rajshahi city. The dimensions of water supply are as follows: technical, biophysical, political, institutional, economic and social.

Findings

The research finds that most of the slum dwellers do not have reliable and sufficient access to water supply. The performance of water supply is location specific, and all of the slums do not have equal access to all dimensions of water supply. Overall performance of water supply is moderate, but individual performances of dimensions are unsatisfactory and unequal among the slums.

Practical implications

The paper suggests location-specific identification of strengths and weaknesses of water supply for the poor. It consolidates a performance evaluation method for identifying priority areas and needs of the urban poor for making Rajshahi city more inclusive and sustainable.

Originality/value

The paper provides an assessment of water supply performance for the urban poor in Rajshahi city, Bangladesh.

Abstract

Purpose

Academic research on the transgenerational performance differences among family firms in Bangladesh is still in its infancy. This paper delves into this issue to answer whether the financial performance of family firms run by second-generation family members is different from their predecessors and nonfamily firms.

Design/methodology/approach

The study employs panel data analysis that attempts to conceptualize the performance difference, quantified in terms of profitability and return, between founder- and second-generation-run public companies in Bangladesh. Moreover, cross-sectional regressions extend the research paradigm to investigate and validate whether heir-controlled family firms perform differently than nonfamily firms or firms that are yet to experience ownership succession within a family.

Findings

The study indicates that family firms perform better when founding family members are in control compared to second-generation-run family firms. Moreover, further analysis suggests that heir-controlled family firms do not show a significant difference in performance compared to firms that never had a family succession in its managerial positions. The implications are that there could be nonfinancial family-centric motivations for family business ownership transition.

Practical implications

Family succession of firm ownership is venerated without necessarily a validation of its financial merit. In Bangladesh, this is too often a de facto transfer of leadership within family firms. This study can act as a reference point to understand that family succession of firm ownership in Bangladesh may not necessarily be in the best financial interest of a firm.

Originality/value

The literature on family firms propounds a plethora of vacillating conclusions and opinions. This paper adds this body of empirical literature into an exercise of formal logic. Such an empirical investigation into the financial performance of Bangladeshi family firms, visualized through the lens of leadership transfer to a second-generation family member, has not been extensively studied in contemporary literature.

Abstract

Purpose

The purpose of this study is to propose an approach to avoid having to trust a single entity in cloud-based applications. In cloud computing, data processing is delegated to a remote party for efficiency and flexibility reasons. A practical user requirement usually is data privacy; hence, the confidentiality and integrity of data processing needs to be protected. In the common scenarios of cloud computing today, this can only be achieved by assuming that the remote party does not in any form act maliciously.

Design/methodology/approach

An approach that avoids having to trust a single entity is proposed. This approach is based on two concepts: the technical abstraction of sealed computation, i.e. a technical mechanism to confine a privacy-aware processing of data within a tamper-proof hardware container, and the role of an auditing party that itself cannot add functionality to the system but is able to check whether the system (including the mechanism for sealed computation) works as expected.

Findings

Discussion and analysis of the abstract, technical and procedural requirements of these concepts and how they can be applied in practice are explained.

Originality/value

A preliminary version of this paper was published in the proceedings of the second International Workshop on SECurity and Privacy Requirements Engineering (SECPRE, 2018).

Abstract

Purpose

This paper aims to develop a simple model for estimating sustainable development goals index using the capabilities of artificial neural networks.

Design/methodology/approach

Sustainable development has three pillars, including social, economic and environmental pillars. Three clusters corresponding to the three pillars were created by extracting sub-indices of three 2018 global reports and performing cluster analysis on the correlation matrix of sub-indices. By setting the sustainable development goals index as the target variable and selecting one indicator from each cluster as input variables, 20 artificial neural networks were run 30 times.

Findings

Artificial neural networks with seven nodes in one hidden layer can estimate sustainable development goals index by using just three inputs, including ecosystem vitality, human capital and gross national income per capita. There is an excellent similarity (>95%) between the results of the artificial neural network and the sustainable development goals index.

Practical implications

Instead of calculating 232 indicators for determining the value of sustainable development goals index, it is possible to use only three sub-indices, but missing 5% of precision, by using the proposed artificial neural network model.

Originality/value

The study provides additional information on the estimating of sustainable development and proposes a new simple method for estimating the sustainable development goals index. It just uses three sub-indices, which can be retrieved from three global reports.

Abstract

Purpose

The coastal zone of Bangladesh that is in the front line of the battle against climate change faced over 200 natural disasters in the past 40 years, and most of the disasters were cyclones. The inevitable cyclone shelter (CS), the backbone of disaster management (DM), provides short-term safety for the disaster victims in Bangladesh. This study aims to explore the community-based limitations and sustainable development features of CSs including the gender issues.

Design/methodology/approach

A questionnaire survey was carried out among 230 community people to identify the requirements and sustainable development features of CSs. A field visit was carried out in 23 CSs to capture its existing facilities. Key informant interviews were conducted in the office of Upazila Engineers to strengthen survey data.

Findings

This research found that the plan of CSs, quality of construction, capacity, facilities, entrance and exit, space allocation, management and policy were not capable enough to fulfill the needs and requirements of the community people. Due to lack of separate facilities, women and girls avoided shelters for fear of sexual and mental harassment in CSs, as they had experiences in the earlier events of cyclones. Insufficient facilities discourage community from using the shelters.

Research limitations/implications

Women and girls were shy to share their experience in CSs. The historical data were limited in the study area. To the best of the authors’ knowledge, this research presents the actual community-based outcome. During CCRIP training program, the authors met 3,625 community people, and participatory discussions were made to explore the participants’ experiences and perceptions about the sustainable development of CSs.

Practical implications

South-Asian coastal zones are prone to natural, quasi-natural hazard and disasters, where shelters are required for protecting lives of community people during such disasters such as cyclones, storm surges, and floods. Therefore, this study can help in making sustainable development decisions in terms of constructing shelters in disaster-prone countries like Bangladesh.

Social implications

The outcomes of this investigation are useful for uplifting psychosocial status to protect lives during disasters such as cyclones, storm surges and floods and increase accessibility to shelters, and users will consider CSs as a social asset. In turn, the acceptability of CSs into community level are expected to be increased for combating against cyclones, storm surges, and floods.

Originality/value

This study introduces the bottom-up approach that refers to the community-based decision-making to identify the limitations and sustainable improvement of CSs. This research contributes to bridging the gaps between decision-makers and users of CSs. From the authors’ field experience, it can be said that this is the first fieldwork regarding the objectives.
