This study aims to assess the effect of water variation on bioethanol production from cassava peels (CP) using Saccharomyces cerevisiae yeast as the ethanologenic agent.

The milled CP was divided into three treatment groups in a small-scale flask experiment where each 20 g CP was subjected to two-stage hydrolysis. Different amount of water was added to the fermentation process of CP. The fermented samples were collected every 24 h for various analyses.

The results of the fermentation revealed that the highest ethanol productivity and fermentation efficiency was obtained at 17.38 ± 0.30% and 0.139 ± 0.003 gL⁻¹ h⁻¹. The study affirmed that ethanol production was increased for the addition of water up to 35% for the CP hydrolysate process.

The finding of this study demonstrates that S. cerevisiae is the key player in industrial ethanol production among a variety of yeasts that produce ethanol through sugar fermentation. In order to design truly sustainable processes, it should be expanded to include a thorough analysis and the gradual scaling-up of this process to an industrial level.

This paper is an original research work dealing with bioethanol production from CP using S. cerevisiae microbe.

The increasing accumulation of synthetic plastic waste in oceans and landfills, along with the depletion of non-renewable fossil-based resources, has sparked environmental concerns and prompted the search for environmentally friendly alternatives. Biodegradable plastics derived from lignocellulosic materials are emerging as substitutes for synthetic plastics, offering significant potential to reduce landfill stress and minimise environmental impacts. This study highlights a sustainable and cost-effective solution by utilising agricultural residues and invasive plant materials as carbon substrates for the production of biopolymers, particularly polyhydroxybutyrate (PHB), through microbiological processes. Locally sourced residual materials were preferred to reduce transportation costs and ensure accessibility. The selection of suitable residue streams was based on various criteria, including strength properties, cellulose content, low ash and lignin content, affordability, non-toxicity, biocompatibility, shelf-life, mechanical and physical properties, short maturation period, antibacterial properties and compatibility with global food security. Life cycle assessments confirm that PHB dramatically lowers CO₂ emissions compared to traditional plastics, while the growing use of lignocellulosic biomass in biopolymeric applications offers renewable and readily available resources. Governments worldwide are increasingly inclined to develop comprehensive bioeconomy policies and specialised bioplastics initiatives, driven by customer acceptability and the rising demand for environmentally friendly solutions. The implications of climate change, price volatility in fossil materials, and the imperative to reduce dependence on fossil resources further contribute to the desirability of biopolymers. The study involves fermentation, turbidity measurements, extraction and purification of PHB, and the manufacturing and testing of composite biopolymers using various physical, mechanical and chemical tests.

This study examined the factors influencing willingness-to-repurchase for each class of airline service, and integrate the constructs of service quality, satisfaction and willingness-to-repurchase which were rooted on Engel-Kollat-Blackwell (EKB) model. The study focuses on the domestic and international arrival of passengers at Murtala Muhammed International Airport in Lagos and Nnamdi Azikwe International Airport in Abuja. Information was gathered from domestic and foreign passengers who had post-purchase experience and had used the airline's services more than once. The survey data were obtained concurrently from arrival passengers at two major international airports using an electronic questionnaire through random and purposive sampling techniques. The data was analysed using the ordinal logit model and structural equation model. From the 606 respondents, 524 responses were received but 489 responses were valid for data analysis and reporting and were obtained mostly from economy and business class passengers. The study found that the quality of seat pitch, allowance of 30 kg luggage permission, availability of online check-in 24 hours before the departing flight, quality of space for legroom between seats, and the quality of seats that can be converted into a fully flatbed are the major service factors influencing willingness-to-repurchase economy and business class tickets. Also, it was found that passengers' willingness to repurchase is influenced majorly by service quality, but not necessarily influenced by satisfaction. These results reflect the passengers' consciousness of COVID-19 because the study was conducted during the heat of COVID-19 pandemic. Recommendations were suggested for airline management based on each class.

Sustainable management requires companies to build up new knowledge to acquire the competencies needed for action. This chapter aims to deliver knowledge about sustainability and knowledge for sustainability. Firstly, we systematically analyse the sustainability literature in the social sciences through a bibliographic analysis and topic modelling using VOSviewer and Mallet software. We outline research directions, themes and critical contributions for each research cluster identified. Additionally, we categorise over 30 definitions of sustainability identified by Meuer, Koelbel, and Hoffmann (2020). Secondly, we enumerate knowledge types needed for effective sustainability transitions of organisations. We trace typologies of sustainable business models and their distinct evaluations of sustainability. In this chapter, we argue that integrating the triad of social, ecological and economic goals is central for sustainability attempts as well as long-term thinking. Therefore, our research offers a comprehensive overview of sustainability in the social sciences supporting researchers and practitioners to navigate this miscellaneous and scattered field. Accordingly, our study is precious to young scholars researching sustainability who want to use the term in an informed and meaningful way.

Malaysia’s industrialised building system (IBS) has been increasingly adopted for sustainable development by the country’s construction industry. However, although it has been used for commercial building projects, its application to sustainable infrastructure development has been limited to date. This study aims to examine the drivers and challenges involved.

A preliminary conceptual framework was initially developed based on a systematic literature review. Semi-structured interviews involving 20 participants were undertaken to gain insightful thoughts from the construction practitioners to discover the perception towards IBS application in the construction industry, the applicability of IBS, particularly in infrastructure projects, the strategies of IBS delivery and the sustainable potential of its application. A two-round Delphi study was conducted with 15 experienced and knowledgeable panellists to further identify, verify and prioritise factors developed from the literature review and interview findings. Then, the results were synthesised and triangulated to demonstrate a holistic insight.

The results show the main drivers to be better productivity, quality, environmental, safety and health, constructability design and cost, policy and requirements, with the main challenges being project planning and cost-related issues, inexperience and industry capacity.

The study’s main contribution is in systematically determining the practical implications involved in applying the IBS to sustainable infrastructure developments in Malaysia and other similar developing countries.

Parkruns are weekly, free, community-based, 5 km runs around open spaces, with a growing body of research indicating their social, physical and psychological benefits. Thirty-one custodial establishments in England and Wales regularly offer parkruns. The purpose of this paper is to consider prisoners' experiences of parkrun in custodial settings, and these are discussed in the context of the evidence base regarding parkrun in the community and the wider literature on prison sport, desistance, and rehabilitation culture.

Using an inductive, qualitative approach, data was collected at three English prisons, via semi-structured interviews with 24 adult male prisoners who participated in parkrun. Data was subjected to thematic analysis.

In total, five themes reflecting positive experiences associated with custodial parkrun were identified: connection with others; healthy living; a safe and predictable exercise environment; a sense of purpose; and a re-humanising experience. Factors appearing frequently in the wider parkrun research are present in the perceptions of parkrunners in custody. In addition, factors deemed important to desistance and promoting a rehabilitation culture were also found in the experiences of the sample.

The work emphasises the successes of His Majesty’s Prison and Probation Service (HMPPS) and parkrun working in partnership to support custodial events. By highlighting the positive experiences of custodial parkrun on prisons and prisoners, the authors anticipate that their findings may encourage further sites to consider launching parkrun events and prompt existing sites to consider their events in line with efforts to promote desistance and a rehabilitation culture.

To the best of the authors’ knowledge, this is the first paper to explore custodial parkrun. The findings indicate that custodial parkrun supports HMPPS strategic goals by offering an opportunity for prisons to promote desistance.

This article reconstructs the conditions under which displaced persons are integrated into their workplaces with their hosts. It identifies the characteristics of this pathway and provides guidance on the support that should be provided to these people. This support is part of social responsibility. Theories on professional integration/labour market integration (LMI) have been categorised and then arranged in a logical order to determine the stages of this integration. Theories on professional integration support for refugees were also reviewed and examined in relation to this categorisation. Six stages characterise professional integration: getting a job, its sustainability and its wage adequacy, its security and sustainability, career continuity and employability, the fact of being a full and equal participant and being an integrated part of the workforce and the meaningfulness of that job. The level of professional integration marks the quality of this integration. Each level encompasses the previous levels. Displaced persons should be supported throughout their careers to go beyond technical and behavioural skills and take a more holistic view of their tasks to find meaning in their work. While most research focuses on getting a job as a characteristic of occupational integration, this study found five other characteristics that were ordered. It also links vocational integration with social responsibility and provides guidance on how to help displaced people reach the final stage of this integration.

Northwest Nigeria is mostly populated by the Hausa and Fulani ethnic groups. Social inclusions and gender equality are listed among the fundamental rights. They are essential for human being to put up their best efforts in resolving all difficulties without restraint. Nonetheless, these rights are frequently withheld in many nations within the African continent, owing to ignorance, religion and custom fanaticism. In spite of these constraints, the northern Nigeria is faced with security issues such as persistent cattle rustling which ultimately evolved into armed banditry, which have exacerbated some lingering issues that revolves around children and women. This study attempts to examine the nature of the crisis that may relates to gender-based issues in Zamfara state. The article relied mostly on secondary literature. Evidences proved that security difficulties have worsened the living circumstances of women and girls in the understudied state, thereby espousing women and girls to dangerous attacks and hard living.

This paper aims to challenge the fashion of ubiquitous artificial intelligence (AI) and the effects which it will have upon society. In doing so it argues that the effects of AI will be minimal but important.

This argument is based upon the Socratic method and explores the Utilitarian background in which AI is based while drawing upon classical literature and other examples to illustrate the argument.

The findings are encompassed in the argument and show that we need to be more open and careful when considering AI and its effects. We also need to be more realistic when considering potential benefits.

This argument has significant implications for the adoption of AI.

The social implications are equally profound and will impact upon our application of AI solutions to current problems and upon humanity more generally.

This is the first paper which relates AI to human successes.

This study delves into the factors that influence the practice of female genital mutilation in West Africa, as well as the health implications. An online cross-sectional study was conducted with the use of electronic questionnaire. The study was targeted at adult females who were between the age of 18 and 50 years old. The Uniform Resource Locator (URL) of the electronic questionnaire was administered on social media platforms (Facebook and WhatsApp) only through convenience and snowball sampling techniques. A sample size of 3,119 adult females participated in the study. Spearman rank correlation (r) was employed to test the hypotheses. Responses were gathered from adult females whom originates from nine West African countries which are Nigeria, Ghana, Mali, Liberia, Benin, Cameroon, Chad, Gambia and Guinea. The study found a strong and positive relationship between culture and the practice of female genital mutilation in West Africa, and there was a weak and positive relationship between religion and education, and the practice of female genital mutilation in West Africa. Despite the health risks, it was revealed that female genital mutilation remained uninterrupted in West Africa. The findings of this study imply that the culture of the people, religious belief system and education are critical factors in efforts to be considered when discouraging the practice of female genital mutilation. Therefore, for healthy living, the practice of female genital mutilation should be discouraged in the study area. Based on the study outcome, recommendations were suggested.
