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.

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.

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.

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.

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

The purpose of this paper is to explore the processes and complexities of community participation in a water supply project for the urban informal poor in Dhaka, Bangladesh.

This paper reviews the performance of a community-based water governance entitled Dushtha Shasthya Kendra Model. The Model includes the local urban poor community with the formal urban service providers in the process of water supply. Using a case study of Karail slum in Dhaka, the paper affirms the potential of community engagement for successful implementation of water supply project by the formal organizations.

The opportunity of community participation by the urban poor helps them to be engaged with the formal organizations. Community engagement not only offers them access to water supply but also ensure formal/legal existence in the city. Despite the fact, the community initiative in the slum faces huge locally situated political and socioeconomic challenges. Addressing these complexities with a proper management may still provide a successful community-based effort for water supply to the urban poor in the slums.

The paper presents a case study of water supply system for the informal poor. Water scarcity in the slum is a serious problem in Dhaka city, though the formal authorities often forget the issue during policy making and planning. This study certainly offers a better understanding of complexity and potentiality of community-based water governance, which may further ensure community participation as well as equal access to water by the urban poor.

What makes neighbourhood environment more walkable is an important question for urban planning and design research. The purpose of this paper is to explore this question through a case study of urban sidewalks in different contexts of urban neighbourhoods in Rajshahi city of Bangladesh.

Using participatory observation, Google street view and photography techniques, it examines the quality of the street facilities by demonstrating physical attributes of sidewalks and by analysing how various obstructions on them characterize neighbourhood walkability environment.

The findings suggest that the unusable sidewalks in Rajshahi city, Bangladesh, are a production of inadequate and inappropriate planning and design that unable to capitalize the functionality of sidewalks as a means of walking. It further argues that the urban planners and designers of streets have paid little attention to the diverse requirements of sidewalks in accordance with spatial and socio-economic categories of urban neighbourhoods.

This study adds insights about the urban sidewalks planning and design in the context of a developing country. It provides an empirical evidence about the constraints and potentials of making a walkable city.

This study analyzed the relationship between mobile financial services (MFS) usage and customer satisfaction with MFS in Bangladesh, considering perception, purpose of use and technical challenges as the primary factors influencing customer satisfaction with MFS. The aim is to determine the factors most influencing the use of MFS.

Data were collected from 400 MFS users through a structured web survey using snowball sampling that is consistent with the nature of MFS users who are difficult to identify or locate. Structural equation modeling (SEM) was used to analyze the data and evaluate the reliability and validity of the measurement model.

The results show that customers’ perceptions and satisfaction significantly impact their intention to use MFS. Specifically, customers’ perceptions strongly influence their satisfaction with MFS, and the purpose of use significantly predicts both perception and satisfaction. Technical problems and challenges were found to have no significant impact on satisfaction levels, but other factors were more critical. Furthermore, the integration of innovative technological solutions is crucial for fostering sustainability in MFS, as it enhances reliability and efficiency while minimizing environmental footprints.

The study was conducted in a single country, relied on self-reported data, and used a cross-sectional design, which limits the ability to draw causal inferences. Future research could explore the factors that influence customer satisfaction with MFS in different countries and regions and incorporate additional variables to provide a more comprehensive understanding of the drivers of customer satisfaction with MFS.

This study significantly contributes by extending the technology acceptance model (TAM) framework with the innovation resistance theory, offering a nuanced understanding of MFS adoption. The findings challenge conventional wisdom, highlighting the limited impact of technical problems on satisfaction and emphasizing the central role of user perceptions in shaping satisfaction and intention to use.

Using the technology acceptance model (TAM), this study investigates factors influencing the adoption of cryptocurrency in Bangladesh.

Data were collected from 346 members of the general public through a structured web survey using snowball sampling. Structural equation modeling was used to analyze the data and assess the reliability and validity of the measurement model.

The results show that knowledge of cryptocurrency, benefits of use (perceived usefulness), attitude and challenges all have a significant impact on the adoption of cryptocurrency.

This study was conducted in a single country, relied on self-reported data and used a cross-sectional design, which limits the ability to draw causal inferences.

This study contributes to understanding the factors driving the adoption of and intention to use technology-based services, providing insights that can inform the design and implementation of future technology-based services.

This study aims to assess the nutritional status and physical fitness status of school children among major ethnic and Dalit populations, in Rajshahi, Bangladesh.

Data were collected through structured questionnaires administered to mothers or caregivers of the children, followed by physical fitness assessments. Anthropometric indicators were used to evaluate nutritional status, including body mass index-for-age, height-for-age, and weight-for-height, based on Centre for Disease Control guidelines. Physical fitness was assessed through tests for flexibility, abdominal, muscular, speed, and lower limb strength. Statistical analysis was performed using SPSS.

Approximately 45% of boys and 55% of girls had normal nutritional status. However, the study also identified varying percentages of children with stunted, underweight, wasted, and mixed nutritional issues, highlighting the prevalence of malnutrition among this population. Boys consistently outperformed girls in terms of physical fitness across all age groups, with 84% to 90% of boys meeting established fitness criteria. Girls face a 1.8-fold and 2.2-fold increased risk of wasted and underweight conditions compared to boys. Lower-income group children exhibit a 2.6-fold and 1.6-fold increased risk of wasted conditions and underweight conditions. Children consuming meals twice a day have a 2.1-fold and 2.5-fold elevated risk of wasted and underweight conditions compared to others.

This study highlights the need for interventions and strategies to improve the nutritional and health status of ethnic children in Rajshahi, Bangladesh, considering their diverse dietary habits and lifestyles. By addressing these issues, the authors can empower these communities to actively contribute to the social and economic development of the region.

This review paper aims to focus on recent advances of carbon nanotubes (CNTs) to produce gas sensors. Gas sensors are widely used for monitoring hazardous gas leakages and emissions in the industry, households and other areas. For better safety and a healthy environment, it is highly desirable to have gas sensors with higher accuracy and enhanced sensing features.

In this review, the authors focus on recent contributions of CNTs to the technology for developing different types of gas sensors. The design, fabrication process and sensing mechanism of each gas sensor are summarized, together with their advantages and disadvantages.

Nowadays, CNTs are well-known materials which have attracted a significant amount of attention owing to their excellent electrical, electronic and mechanical properties. On exposure to various gases, their properties allow the detection of gases using different methods. Therefore, over recent years, researchers have developed several different types of gas sensors along with other types of sensors for temperature, strain, pressure, etc.

The main purpose of this review is to introduce CNTs as candidates for future research in the field of gas sensing applications and to focus on current technical challenges associated with CNT-based gas sensors.

Governance can often be assessed as one part of directing companies’ action toward something better. This study examines how governance quality at the country level and firm level can affect sustainability performance that aligns with sustainable development goals (SDG). Prior academic literature explains that if a country has a low institutional condition, it is a great challenge to implement sustainability. However, the internal awareness of the company to implement sustainability plays an important role as well. To examine the research question, this study uses the banking sector as a research sample with an observation period from 2017 to 2019. Prior literature overlooks research in the banking sector and does not feature country-level governance with firm-level governance. The data were collected either from the annual report or sustainability report, which comprises 141 companies, with the total observation of 423 firm-year. This study used panel data regression analysis and was based on the Hausman Test; it shows that random effect is used to test the hypothesis. This research finds that good quality governance at the country level, results in good sustainability performance. However, contrary to expectations regarding the quality of firm-level governance, which is thought to be positively related to sustainability performance, this study found a negative relationship. The argument that might answer the finding is the existence of governance conditions at the state level and at the firm level that mutually subsidize each other. This research contributes to policymakers continuing to provide counseling and improve institutional conditions to motivate companies to support the achievement of the SDGs. Companies should also pay attention to the effectiveness of their internal governance and strive to use stakeholder opinions as a guide in the realization of SDGs.

The purpose of this paper is to review the topic “urban green space” focusing on its social benefits and measure techniques in terms of monetary value and accessibility. It suggests potential research direction by using an integrated valuation and measurement framework, and concludes that urban green space valuation in the providers’ perspective as well as accessibility analysis in the consumers’ perspective are useful tools that provide significant measure techniques in urban green space planning.

The paper uses a systematic approach to build up a conceptual framework that quantifies social benefits of green space from provider and consumer perspectives. The literature review indicates some limitations of existing techniques of valuation and accessibility analyses, which entails an integrated model of measurements.

The paper explores social benefits of urban green space, which includes recreational opportunities, aesthetic enjoyments, adjusting psychological well‐being and physical health, enhancing social ties, and providing educational opportunities. To analyze existing evaluation and measure techniques of urban green space, the paper points out that a single measurement only evaluates certain aspects of urban green space, which may not always be suitable to comprehensively assess social benefits from both providers’ and consumers’ perspectives. Considering this limitation, the paper offers an integrated model to measure urban green space that may deal with current limitations.

The originality of the study resides in designing an integrated model including valuation and measure techniques. It certainly offers an important avenue to evaluate social benefits of urban green space.

This paper aims to provide a conceptual framework to analyse whether the global concept of sustainable city, generally produced as a goal in the cities of the global North, will be equally suitable in the cities of the global South or not.

Research has been based on a review of the literature, which has been collected from books, journals, reports and soft‐materials of the internet. A simple descriptive analytical approach is followed to examine the argument. The paper argues that a sustainable city should not be a goal, but a principle of effective service provisions based on social equity and justice.

Despite the main premise that a sustainable city is to achieve environmental, social and economic sustainability, the concept is widely criticised due to its disputable application in the cities of the South. The paper suggests that the sustainable city discourse does not include the main problems of the cities in the global South, even though, as a goal, it is efficient and effective in the developed countries of the global North. Thus, the paper concludes that a goal‐based sustainable city discourse of the global North will be misleading and inappropriate for the sustainable urban development in the cities of the global South.

Despite the widespread application of the sustainable city concept in developing countries, cities are facing numerous social, economic and environmental problems. Realising this fact, it is imperative to investigate the root‐causes of the problems. In line with this thinking, the paper offers a conceptual framework to analyse urban development policies in the cities of the global South.
