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 chapter presents the strategy employed to develop a methodology to evaluate research collaboration networks in a higher education context. The research design comprised four successive tracks. We understand these methodological tracks as the tactics employed to organise available means to accomplish an objective. In the first track, we selected the key subjects, the ego networks and the network leaders to be analysed. In the second track, we visualised networks through graphs. In the third track, the statements of the subjects about formed networks were pursued, based on interviews. In the fourth track, case studies were researched and described. The study included qualitative and quantitative data to uncover the interactive processes of doing collaborative research inside a network. The methodology was useful to obtain visual understanding of the networks of co-authorial relations, quantitative and qualitative markers to be used in participatory evaluation of collaborative research networks, as well as an extended view of the life cycles of collaborative research networks. The main contribution of the chapter is to show a sequence of cross-disciplinary methodological steps allowing to understand different types of relations inside research network.

Purpose – In this research, we have prepared activated carbon (AC) from the waste of banana peels (Musa acuminate L.) using potassium hydroxide (KOH) for carbon monoxide (CO) adsorption from motorcycle gas emission.

Design/Methodology/Approach – The activation was conducted using a chemical activator (KOH) at various concentrations of 1, 2, and 3 N for 1, 2, and 3 h, respectively. Characteristics of banana peels AC (BPAC) produced were analyzed using the Fourier-transform infra-red spectroscopy and scanning electron microscopy.

Findings – Results showed that KOH concentration and activation time strongly affected the CO adsorption and opening of the AC surface pore. There was an increase in the CO sorption when the KOH concentration was increased up to 3 N concentration. The highest CO adsorption from the emission occurred at 70.95% under KOH concentration of 3 N during the 3-h preparation.

Research Limitations/Implications – BPAC has been used as an adsorbent for only CO from motorcycle gas emission but not as an adsorbent for HC, NO, NO_x, or H₂S.

Practical Implications – BPAC can be used as the potential adsorbent for the removal of CO from motorcycle gas emission, and it is an environmental friendly, low cost, and easy to make adsorbent.

Originality/Value – In this study, the AC is made from biomass and is used in wastewater treatment, but limited studies are found on the removal of CO from motorcycle gas emission.

Homelessness has many causes and also is stigmatized in the United States, leading to much misunderstanding of its causes and what policy solutions may ameliorate the problem. The problem is of course getting worse and impacting many communities far removed from the West Coast cities the authors examine in this study. This analysis examines the socioeconomic variables influencing homelessness on the West Coast in recent years. The authors utilize a panel fixed effects model that explicitly includes measures of healthcare access and availability to account for the additional health risks faced by individuals who lack shelter. The authors estimate a spatial error model (SEM) in order to better understand the impacts that systemic shocks, such as the COVID-19 pandemic, have on a variety of factors that directly influence productivity and other measures of welfare such as income inequality, housing supply, healthcare investment, and homelessness.

To begin, therefore by establishing certain parameters to both delimit and evoke the discussion, one might first note before side-stepping the well-recognised ethical issues that announce themselves within these early ethnological texts (see for instance Hsu, 1979). The ‘pith-helmet’ terminology and exoticised intentionality, borne with such unselfconscious assurance, can in fact serve to effect complacency on the part of the contemporary ethnographer – were they to believe that one could completely escape such tendencies. In fact, Western thought has always displayed just these acquisitive geometries in its surveying, arraying and apprehending of the world.¹ Obviously, therefore, this is not to criticise in a naive or petulant manner a fundamental comportment of the Western intellectual tradition, which clearly structures this and every enquiry couched within its terrain. Nor is it to suggest that certain keywords (‘colonialism’ for example) might somehow name this tendency without repeating its form, or that earnest mantras concerning ‘emancipation’ or ‘respect for alterity’ immediately authorise its continuation. For one to deal responsibly with the ensuing philosophical and ethical motifs would require a measured and careful analysis beyond the remit of the present discussion. Nonetheless, the basic geometry of this disposition is assumed for ethnography in the analysis that follows. Ethnography, that is to say, is actively oriented towards an object, here referred to variously as ‘lived experience’ or ethnos, and is always to some measure engaged in the apprehension and transmission of that object.

This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

The first aim of the chapter is to offer a characterization of back-reshoring as a possible step of the firm’s nonlinear internationalization process. The second aim is to review the empirical literature on back-reshoring and to complement it with the findings of an extensive data collection.

In this chapter we adopted an explorative approach building on both theoretical and empirical literature from the fields of international business and international operations Management. We also collected secondary data on back-reshoring decisions in order to define the magnitude of the investigated phenomenon and to offer a primary characterization.

Our findings confirm that, though it cannot be considered a generalized trend, back-reshoring is a very topical issue for international business scholars. It represents an autonomous phenomenon consistent with the idea of nonlinear internationalization process.

The chapter is based on cross-sectional data. Longitudinal research is required in order to address the proposed research questions and help understanding “how much” and what kind of manufacturing will be housed in western countries in the near future.

This is the first attempt to conceptualize back-reshoring as a possible step of the firms’ internationalization process. It is also the first chapter that summarizes and discusses the literature and empirical evidence on back-reshoring emerging from a wide range of countries.

Currently, Mauritius is adopting landfilling as the main waste management method, which makes the waste sector the second biggest emitter of greenhouse gas (GHG) in the country. This presents a challenge for the island to attain its commitments to reduce its GHG emissions to 30% by 2030 to cater for SDG 13 (Climate Action). Moreover, issues like eyesores caused by littering and overflowing of bins and low recycling rates due to low levels of waste segregation are adding to the obstacles for Mauritius to attain other SDGs like SDG 11 (Make Cities & Human Settlements Inclusive, Safe, Resilient & Sustainable) and SDG 12 (Guarantee Sustainable Consumption & Production Patterns). Therefore, together with an optimisation of waste collection, transportation and sorting processes, it is important to establish a solid waste characterisation to determine more sustainable waste management options for Mauritius to divert waste from the landfill. However, traditional waste characterisation is time consuming and costly. Thus, this chapter consists of looking at the feasibility of adopting machine learning to forecast the solid waste characteristics and to improve the solid waste management processes as per the concept of smart waste management for the island of Mauritius in line with reducing the current challenges being faced to attain SDGs 11, 12 and 13.

This chapter provides a genealogy of the Gladue–Ipeelee principle of special consideration of Indigenous circumstances at sentencing. The principle is codified in the 1996 statutory requirement that “all available sanctions other than imprisonment … should be considered for all offenders, with particular attention to the circumstances of Aboriginal offenders” (s. 718.2e of the Criminal Code of Canada). Using the Foucaultian genealogy method to produce a “history of the present,” this chapter eschews normative questions of how s. 718.2e has “failed” to reduce Indigenous over-incarceration to instead focus on how practices of “special consideration” reproduce settler-state paternalism. This chapter addresses three key components of the Gladue–Ipeelee principle: the collection of circumstances information, the characterization of those circumstances, and finally their consideration at sentencing. Part one focuses on questions of legitimacy and authority and explicates how authority and responsibility to produce Indigenous circumstances knowledge was transferred from the Department of Indian Affairs (DIA) to Indigenous Courtworker organizations in the late 1960s/early 1970s. Part two identifies how authority shapes problematization by examining the characterization of Indigenous circumstances in the two eras, finding that present-day Gladue reports articulate an Indigenous history and critique of colonialism as the root cause of Indigenous criminalization, whereas DIA reports prior to 1970 generally characterized this criminalization as a “failure to assimilate.” Part three focuses on the structural reproduction of power relations by exploring historical continuities in judicial and executive-branch consideration of Indigenous circumstances, suggesting that the Gladue–Ipeelee principle reinscribes a colonial “mercy” framework of diminished responsibility. The author discusses how the principle operates in the shadow of Indigenous over-incarceration as a form of state “recognition” and a technique of governance to encourage Indigenous participation in the settler justice system and suggests that the Gladue–Ipeelee principle produces a governing effect that reinforces settler-state authority by recirculating colonial practices and discourses of settler superiority.
