The purpose of this study is to understand the complex interplay between illicit opioids trade and consumption practices and state policies that aim to reduce their misuse.

The study adopted an exploratory design. Data were gathered through in-depth interviews with 31 commercially oriented drug dealers in Uyo, Nigeria. The framework approach was used in data analyses, while “friction” provided the interpretive lens.

Accounts revealed public concerns over the misuse of tramadol and other opioids among young people and the associated health and social harms. These concerns provided support for enforcement-based approaches to prescription opioids control, including police raids on pharmacy stores. These measures did not curtail opioids supply and consumption. Instead, they constrained access to essential medicines for pain management, encouraged illegal markets and fuelled law enforcement corruption in the form of police complicity in illegal tramadol trade.

The findings reveal the frictions of drug control in Nigeria, wherein enforcement-based approaches gained traction through public concerns about opioids misuse but also faced resistance due to the persistence of non-medical use and illegal supply channels made possible by law enforcement complicity. These indicate a need to prioritize approaches that seek to reduce illegal supply and misuse of opioids while ensuring availability of these medications for health-care needs.

The study is unique in its focus on the creative tension that exists between state control measures and local opioids supply and consumption practices.

This paper aims to explore the misuse of prescription opioids, associated consumption cultures and the emergence of “informal governing images” among young men in Nigeria.

Using a qualitative research approach involving purposive sampling: six in-depth interviews, one focus group discussion and key informant interviews with two health-care professionals using the transgressive theory approach, this paper explores consumption cultures, motivations and the resultant “informal governing images” associated with the misuse of prescription opioids among young local street high-risk users in Nigeria.

Findings show complex expressions of diverse consumption practices, such as grinding, sniffing and concoction of tramadol (TM)with other opioids. The “puff-puff pass” practice serves as induction for new users of opioids commonly accessed through street drug dealers and pharmacists sold via backdoors. Codeine mixtures with different brands of soft drinks for dilution are used to achieve a “lower high” while a concoction of different opioids, with alcohol, and spirits obtains a “higher high”. Manufacturers’ indelible colouring and bottling discourage the non-medical use of opioids. Desiring to be awake for nocturnal activities, mostly “yahoo-yahoo” (internet fraud), sexual enhancement and dosage competitions, are motivations for the non-medical use of prescription opioids. These consumption cultures create “misuse circuits”, leading to the emergence of “informal governing images” triggered by threats from formal controls.

This paper, therefore, concludes that pharmaceutical industries should also add colourings to TM and codeine just like they did in rophinol to discourage the non-medical use of prescription opioids among young people in Nigeria.

This paper concludes that rather than branding and packaging in such a way that concealability is difficult for high-risk users as the best way to discourage the non-medical consumption of prescription opioids in Nigeria, the focus should be on addressing youth poverty and unemployment and improving access to treatment for drug use disorders, instead of calling for more enforcement-based measures.

This is an original research.

This study aims to provide and illustrate the application of a framework for conducting techno-economic analyses (TEA) of early-stage designs for net-zero water and energy, single-family homes that meet affordable housing criteria in diverse locations.

The framework is developed and applied in a case example of a TEA of four designs for achieving net zero-water and energy in an affordable home in Saint Lucie County, Florida.

Homes built and sold at current market prices, using combinations of well versus rainwater harvesting (RWH) systems and grid-tied versus hybrid solar photovoltaic (PV) systems, can meet affordable housing criteria for moderate-income families, when 30-year fixed-rate mortgages are at 2%–3%. As rates rise to 6%, unless battery costs drop by 40% and 60%, respectively, homes using hybrid solar PV systems combined with well versus RWH systems cease to meet affordable housing criteria. For studied water and electricity usage and 6% interest rates, only well and grid-tied solar PV systems provide water and electricity at costs below current public supply prices.

This article provides a highly adaptable framework for conducting TEAs in diverse locations for designs of individual net-zero water and energy affordable homes and whole subdivisions of such homes. The framework includes a new technique for sizing storage tanks for residential RWH systems and provides a foundation for future research at the intersection of affordable housing development and residential net-zero water and energy systems design.

The effects of population growth in the developing world and climate change have increased the stress on available water resources. The majority of Rajshahi city, Bangladesh, is facilitated with groundwater withdrawal. As Bangladesh is a country of monsoon climate, reserved rainwater can be contributed as an alternative to extracted groundwater. This study aims to develop a framework for rooftop rainwater harvesting (RRWH) for domestic purposes and estimate the appropriate size of the storage tanks and their costs required to fulfill the annual drinking and cooking water demands through RRWH in Rajshahi city of Bangladesh.

A total of 100 single-story residential dwellings with varying rooftop areas were surveyed for the projection of RRWH potential. The relationship between the size and cost of a water tank and the rooftop areas of different houses is expressed using a general mathematical equation. Cost estimates for the proposed RRWH system for all houses have been completed, and a cost model illustrating the relationship between rooftop or catchment area and associated cost of RRWH system has been developed.

This study reveals that a maximum of 110.75 m³/year rainwater can be collected from a 100 m² rooftop area of Rajshahi city. Moreover, this study finds that such harvesting of rainwater can reduce municipal water supply to the extent of almost 75%. Water samples collected from rooftops also revealed that if germs were removed through bacteria treatment, the collected rainwater potentially can be used for drinking and cooking purposes.

The novelty of this study is that it focused mainly on how significant RRWH can be to meet people’s daily required amount of water for household purpose and ascertain the cost reduction using the RWH method. This paper also is unique as it assessed the volume of the storage tank that is sufficient to distribute the necessary amount of water for drinking and cooking purpose as a sustainable alternative source in the dry season.

This work aims to develop a web platform for inspecting roof structures for technical assistance supported by drones and artificial intelligence. The tools used were HTML, CSS and JavaScript languages; Firebase software for infrastructure; and Custom Vision for image processing.

This study adopted the design science research approach, and the main stages for the development of the web platform include (1) creation and validation of the roof inspection checklist, (2) validation of the use of Custom Vision as an image recognition tool, and (3) development of the web platform.

The results of automatic recognition showed a percentage of 77.08% accuracy in identifying pathologies in roof images obtained by drones for technical assistance.

This study contributed to developing a drone-integrated roof platform for visual data collection and artificial intelligence for automatic recognition of pathologies, enabling greater efficiency and agility in the collection, processing and analysis of results to guarantee the durability of the building.

The purpose of this paper is to identify the key aspects of building defects performance cases in relation to the building components focusing on the government-owned buildings and to enhance government’s role to curb the building defects to reoccur.

The qualitative research method approach was adopted with a total of 5,243 specific building defects identified and accumulated from actual building projects and provided feedback on the defects associated with the Government of Malaysia’s owned buildings.

This paper statistically validates that building defects are a staid delinquent matter fronting the construction industry in Malaysia. This matter needs to be tacked by all the parties involved in the industry. This paper proposes a factual statistical statement that is proved to be a practical and suitable measurement in correcting building defects and preventing them from reoccurring.

Future research could focus on developing a defect performance measurement on real projects now focusing on private buildings as well.

The defects performance statistical measurement is anticipated to prove the problematic rate of defects occurrence on government-owned structures, as the key elements on the national defect preventive strategy which have to be taken into account.

The outcome of this paper is significant in its own right and serves as a platform for future research in this area.

This paper aims to examine landlords’ health support systems to tenants to control COVID-19 in selected informal settlement rental housing (ISRH) in Ghana, dwelling on landlords’ views.

The paper used the concurrent imbedded mixed-methods approach and grounded the findings in the socio-ecological theory. The authors collected both qualitative and quantitative data from 242 landlords in 13 informal settlements across Ghana using quotas. The authors undertook semi-structured face-to-face and telephone interviews. The authors conducted content and thematic qualitative data analysis and used simple descriptive statistical data analysis.

The paper discovered that tenants had limited knowledge on the transmission of the pandemic, forcing landlords to regulate their building services usage, ventilation and thermal control, entertainment, common areas and rent advancement for tenants to control the pandemic. Also, tenants found it difficult to comply with the rules on ventilation for fear of criminal attacks, while high social connection and interaction among renters and inadequate enforcement caused the non-adherence by renters to social gathering. Again, landlords had difficulty in contract-tracing visitors suspected to be infected with the virus.

The use of concurrent and imbedded mixed methods to investigate landlords’ viewpoints on their support in health needs of their tenants to regulate COVID-19. The prescriptions from the study provide practical applications to formulate a mix of housing and health policies to formalize the support of landlords to their tenants in ISRH in Ghana.

The United Nation's 2030 mission provides scholars, practitioners and governments with a valuable framework to direct their research in a way that tackles societal issues. Towards this aim, some key Sustainable Development Goals focus on improving the well-being of humans and societies; however, the literature dealing with individual financial well-being is still underdeveloped and fragmented. To address this significant research gap, this paper reviews the literature on financial well-being. It provides an in-depth analysis of different theories, mediators and moderators employed in financial well-being studies to deepen the theoretical framework and widen the scope of financial well-being research.

Using the Web of Science Core Collection database (WoS), the literature on financial well-being was reviewed (n = 32) following a systematic review approach.

Findings revealed that (a) there is a limited application of theories in financial well-being studies (n = 19) with the majority of studies (n = 15) employing only one theory; (b) twenty-one different theories were used with the maximum number of theories employed by any study was four; (c) the theory of planned behavior was the most commonly used (n = 4); (d) While a reasonable number of studies examine mediators and moderators in antecedents-financial well-being relationships, studies examining mediators and moderators relationships in financial well-being-outcomes relationships are limited. Based on these findings, this review identified a need for future theory-based financial well-being research and examining the role of underlying and intervening mechanisms in antecedents-financial well-being-outcomes relationships.

The study concludes by suggesting some relevant theories and prospective variables that can explain potential financial well-being relationships. To the best of the author's knowledge, this is the first review on the use of theories, mediators and moderators in financial well-being studies.

In the space of slums are many stakeholders; the extent to which their assistance contributes to slum administration is sparsely studied. The study aims to examine how external stakeholders contribute to slum administration within the Ghanaian context.

Using the stakeholder theory, the study used an exploratory qualitative design based on face-to-face, in-depth interviews among 21 respondents. Participants were purposively selected from stakeholder organisations and slum residents based on the stake in slums governance in Ghana.

The results indicate that stakeholders have contributed towards slums livelihoods in the general areas of housing, trading, skill development and capacity building. It shows that stakeholders’ contributions tend to enhance slums’ living conditions and affect local assemblies positively. The study finds that slum dwellers categorise stakeholders’ contributions as short-term relief and long-term solutions. Additionally, it emerged that in the areas of policy design, implementation and policy feedback, external stakeholders have supported the government in that regard.

The conclusion drawn from the study is limited to the four communities and the stakeholder organisations. However, communities with similar characteristics globally might benefit from the findings.

The study uncovers a context-specific role and assistance of external stakeholders in the domain of slums. This provides a guide to the government regarding key areas of stakeholder collaboration towards slum governance in the Ghanaian context. Theoretically, this study has contributed to new knowledge about stakeholders’ contribution to the overall governance of slums.

The study expands the frontiers of knowledge in the field of slum administration by focusing on external stakeholders. This study departs from previous studies, which have examined, in broader perspectives, stakeholders’ roles within the space of slums.
