Beyond Vicarious Storytelling: How Level Telling Fields Could Help Create a Fair Narrative on Migration

Life stories play a crucial role in migration discourses: they serve as testimony in journalistic work, form the core of ambassadorial storytelling by non-governmental organizations (NGOs), and inspire collaborative projects initiated by writers seeking to express their solidarity. However, this article argues, drawing on migrants’ experiences for such purposes also creates an ethical dilemma: speaking about–or even for–rather than with migrants assigns them a passive role and tends to recycle existing narrative patterns and templates. Starting with a generic distinction between what we call stories of migration (various forms of self-expression granting migrants full authority and control over their narrative) and narratives on migration (external perspectives, e.g., academic, economic, political, and legal approaches, detached from lived experience), we explore the extensive middle ground of hybrid forms between these two extremes–i.e., different kinds of vicarious storytelling–before addressing their ethical implications. We further discuss how the metaphor of the level playing field, a key concept in economics, can be used in transdisciplinary research projects to establish level telling fields (LTFs), i.e., communicative spaces characterized by a fair dialogue on an equal footing for all participants.

The application of chromatographic methods in optimization and the enhancement of the oxidative liquefaction process to wind turbine blade recycling

AbstractThe concept of the circular economy aims to maximise the longevity of raw materials, materials, and final goods while simultaneously minimising waste generation. In order to accomplish this objective, researchers are currently exploring emission-free recycling methods and advancing a novel oxidative liquefaction methodology. This process is employed to efficiently degrade the polymer matrix which we can find among other things in wind turbine blades while also conducting chromatographic investigations of the resulting degraded resins. The conducted experiments included a temperature range spanning from 250 °C to 350 °C. The residence lengths varied from 30 to 90 min, while the pressures ranged from 20 to 40 bars. Additionally, the waste-to-liquid ratios were within the range of 5–25%, and the oxidant concentrations were between 15 and 45% by weight. The study’s results will help improve the design of the experiments by focusing on getting the highest concentrations of oxygenated chemical compounds, such as volatile fatty acids, aromatic hydrocarbons, and aromatic carboxylic acids. These compounds are the main chemicals obtained during resin degradation, and identifying the optimal conditions for their production will facilitate the implementation of this process on a larger scale.

Value switching: Extracting profit from the city

Land and property, and the wealth extracted from it, has reappeared as a central concern in understanding the process of urbanisation under capitalism. Much of the academic discussion centres on the re-emergence of ‘rentier capitalism’ drawing on 19th-century concepts of land economics. However, the accumulation of wealth through property ownership and the development process points towards a value proposition contained in the land question that is not satisfactorily explained by notions of ‘rent’ or ‘rentier’ capitalism, rooted as they are on 19th-century concepts of the land development process. This article seeks to extend this debate by exploring multiple regimes of value that underpin the contemporary urban development process. The first part of the article maps out four intersecting regimes of land value, before arguing by reference to empirical analysis of land and property sales data in Sydney Australia that switching between these value regimes – value switching – is a key transformative moment in the urban development process. Specifically, this article argues that value switching, as triggered by the land use planning process, has become the key driver of urban development dynamics and adds a further dimension to theories on land and housing development in the financialised city.

Transforming discarded walnut green husk into a resource of valuable compounds for colored bioactive textiles with a focus on circular economy concept

This study takes a new look at a circular economy concept for discarded walnut green husks. Their ethanol extract was prepared and characterized using RP-HPLC, then diluted with water and employed for dyeing and/or functionalizing different fabrics. A diluted extract can dye wool (WO), cotton (CO), cellulose acetate (CA), and polyamide (PA) at pH 4.5. Extract:water ratio of 10:40, 65 °C and 75 min and extract:water ratio of 15:35, 45 °C, and 60 min were found suitable for dyeing WO and CA, respectively. Dyed WO and CA exhibited color strength values of 29.0 and 9.2, and excellent antioxidant activity (>97 %) before and after washing, and a significant level of efficacy against S. aureus. CA possessed excellent (5) and very good (4) color fastness to rubbing in a dry and wet state, respectively. WO showed very good (4) and good to very good (3–4) color fastness to rubbing in a dry and wet state, respectively. CO and PA displayed excellent antioxidant activity, with CO also exhibiting significant antibacterial activity against S. aureus even after washing. Moreover, the same dyebath can be reused for up to four dyeing cycles, enabling obtaining bioactive WO and CA fabrics in various brown shades suitable for different applications. Cytotoxicity assay confirmed the non-cytotoxic nature of dyed and washed CA, PA, and CO fabrics. Bioactive WO, CO, CA, and PA fabrics can be considered for the production of wound dressing, performance clothes, and tights for people with sensitive skin. Finally, this paper sheds new light on a novel circular economy concept since collected husks’ solid parts that remained after extraction were converted into activated carbon, which was then used for the preparation of supercapacitor having a specific capacitance of 144–275 F/g at current densities 0.1–2.0 A/g.

The hidden concept and the beauty of multiple “R” in the framework of waste strategies development reflecting to circular economy principles

There are numerous unresolved research questions, along with ongoing debates, regarding how to achieve a circular economy and at what level. The forthcoming circular economy standard (ISO 59000 framework, ISO59010) as a result from the ISO/TC 323, from the International Organization for Standardization (ISO) aims to offer global implementation pathways using a unified technical language. The most challenging aspect of circularity, whether viewed scientifically, technically, and/or legislatively, is how to enhance prosperity while reducing reliance on primary materials and energy to achieve climate neutrality by 2050, thereby aiding the EU in achieving a successful and equitable transition towards a sustainable future. Strategies in the framework of waste management and circular economy are essential and needed to reduce the impact of several processes on the environment through product, processes, and corporate policies using green applicable sustainable resources and environmental management systems. In addition, “measuring something that is not there” is very complex and not fully comprehensible, not clear and not tangible from organizations, researchers, policy makers and citizens. The willingness and ability of individuals or organizations to take actions towards a low-carbon society involves grappling with various perspectives, such as social norms and economic viability. Circular economy is considered a tool in combating climate change and implementing climate mitigation (as well as adaptation) measures. Moreover, to date, there has been no common scientific or technical language for the application of the circular economy concept. This paper highlights the multitude of “Rs” beyond the well-known (3Rs) Reduce-Reuse-Recycle pattern, which can be applied in various contexts to assist SMEs (Small and Medium Enterprises), organizations and even citizens successfully adopt circular economy principles. Is also explores how these “Rs” can be utilized to measure intangible aspects (something that is not there). The results indicate that more than 55Rs exist which directly involved in the circular economy framework, also considering waste management strategies. The findings of this study reveal the existence of over 100 “Rs” beyond the well-known principles of “reduce, reuse, recycle,” each playing a distinct role in the development of strategies aimed at addressing waste management issues and advancing circularity towards a low-carbon society. Furthermore, the results could be useful for any policy makers, consultants, engineers, practitioners, urban planners, academics etc., in order to develop, apply, monitor, measure and improve any strategy such as circular economy strategy, waste prevention, zero waste, reuse, reduce, energy recovery etc., in the framework of circular economy principles, solid waste management and beyond.

Civilization Approach in Economic Researches

The proposed article presents the author’s view on how the civilizational approach to the analysis of economic processes developed and what it consisted of in various predominantly Russian-language literary sources of the 19th century. The author recognizes that the volume of sources containing evidence of such an approach is immense, so he focuses on those that he considers the most important and indicative for assessing the contribution of Russian science to the development of such a methodology of economic analysis, as well as the modern concept of human economy, to which some of the author’s earlier works were devoted. In the author’s opinion, the civilization approach already at the early stages of economic research helped to bring out non-material, cultural-psychological and moral aspects of economic behavior and formation of economic institutions. Most studies of the impact of civilizational development on the economy demonstrate a certain one-directionality, that is, they are built in the logic of a hierarchical world order: civilized nations are at the top of the pyramid of development, and uncivilized, barbaric nations are located somewhere at its base. The civilizational approach allows us to abandon the “economism”, which has become a template, based on the exclusive recognition of the primacy of material factors of social development. In addition, in the author’s opinion, there is an opportunity to raise the question of the correctness of the multipolarity concept, which can no longer describe in detail the formation of a new world order. The civilizational approach gives a chance to assess the processes of globalization and fragmentation in a new way, not as antagonistic processes, but as mutually conditioned. In general, the future development of a multi-civilizational world order and its conflict-free nature will be largely determined by the willingness of representatives of primarily Western civilization to recognize the need to gradually abandon the paradigm of universality of social development conditions in favor of manners identity paradigm, uniqueness of economic structure and behavior, and the importance of identity for economic development.

Investigating the effect of circularity index on a closed loop supply chain with multi-shipment policy

Environmental sustainability has emerged as a crucial aspect for every business, as the wastage of used products greatly contributes to greenhouse gas emissions and environmental hazards. Adopting the circular economy concept is essential to address this problem. This approach prioritizes reliability and re-manufacturability, aiming to simultaneously reduce waste and enhance sustainability and profitability. In this context, the proposed model introduces a sustainable closed-loop supply chain model wherein the manufacturer oversees the production process and delivers requested batches to the retailer under the single order and multi-shipment policy. The model incorporates the notion of circularity, quantified by a circularity index representing the degree to which the product's circularity level. The level of product circularity can be enhanced by material choice, supplier selection, and innovative design while manufacturing. The model being presented aims to maximize the total integrated profit of the closed-loop supply chain system by optimizing the number of shipments as well as the circularity index. It is evident from the analysis that the circularity index significantly influences profits and environmental sustainability by increasing product demand and extending product life cycles. Notably, the numerical example provided in the model illustrates that accounting for the effects of the circularity index results in an optimal profit up to 5% higher compared to scenarios where such effects are not considered.

Creative and Innovative Digital Economy Training to Increase Income of SMA Karya Utama Students

Abstract: The creative and innovative digital economy, fuelled by digital technology and the internet, offers numerous opportunities for individuals to increase their income. Shopee, a widely recognised e-commerce platform, effectively taps into this potential with its user-friendly services. SMA Karya Utama, a 22-student senior high school located at Jalan Pendidikan No. 23 Marindal Village, Patumbak District, has yet to fully comprehend the potential of e-commerce for entrepreneurship, as evidenced by the PKM team's survey. To bridge this gap, the PKM team aims to educate SMA Karya Utama students on the opportunities presented by the digital economy and how to utilise the Shopee app for sales. The PKM activity employed a variety of socialisation, demonstration, and practical methods to expose students to creative digital economy concepts and train them in the operational aspects of Shopee. The results of this activity included increased knowledge of the digital economy and practical skills in account creation, product uploading, store management, and marketing on Shopee. The training aimed to empower SMA Karya Utama students to increase their income, foster independence, and equip them to effectively face future economic challenges.

Emergent concepts in local economic development

This paper identifies and explores the local economic development concepts that are the focus of the most highly cited papers published between 2013 and 2023. It finds that many emergent concepts describe the functioning of modern, knowledge-intensive economies (agglomeration, innovation ecosystems, mission-led innovation, global production networks, Industry 4.0, smart cities and institutions) and the uncertainty they are experiencing (economic resilience, gig economy and work from home). Other concepts deal with the opportunity associated with greater inclusion (female entrepreneurship) and the changing nature of rural economies. Finally, substantial emerging literature tackles the opportunities and challenges associated with the transition to an economy that does not outstrip the planet’s natural resources (clean energy transition, circular economy and degrowth). These ideas do not reconcile easily into a coherent framework. The challenge for local economic development practitioners is to work in partnership with others to integrate these concepts into an approach that makes sense for their communities.

The moral economy of student debt: A pharmacological approach

Over the past three decades, student debt has surged in most English-speaking countries. Despite this trend, enrollment at universities has steadily risen, which testifies to the enduring appeal that higher education still exerts on middle-class individuals and families. Nevertheless, the policies responsible for this growing indebtedness have also stirred up their share of controversy. In an attempt to make sense of these debates, this article focuses mainly on the English and American cases to demonstrate how moral arguments have been put forth both in favor of and against using credit to finance education. Because it shows the ambivalent and unstable nature of the normative principles underpinning debt relations, the concept of moral economy is particularly well suited to discuss this phenomenon. On one hand, it explains how certain ethical expectations seemingly justify the need to incur debt for educational pursuits. On the other hand, it also shows why the perceived legitimacy of student debt eventually comes to be challenged. At its core lies an undecidable choice between antinomic values, as the decision to study on credit involves both a striving for personal autonomy and subjecting oneself to an exploitative relation of dependence. Recognizing this fundamental ambivalence, the article develops a ‘pharmacological approach’ to address the issue of student debt, aiming to better grasp the social and political tensions surrounding higher education in neoliberal societies.

Making “Enemies”: Industry‐State Subterfuge and US Fair Trade Practices Towards Non‐Market Economies Since 1960

AbstractStudies on US “non‐market economy” (NME) antidumping (AD) policy frame its origins as either an ideological relic of the Cold War or as a case of regulatory capture informed by strategic filing patterns. While these insights are invaluable, they do not address the underlying social processes which inform the creation of economic concepts in the first instance. NME policy evolved out of the legal‐discursive tactics employed by the US steel industry hoping to receive relief from imports, and a US state which had to simultaneously provide a form of protection to the steel industry and maintain an international commitment to free trade. Steel and the state used legal subterfuge to achieve these goals. Accordingly, NME policy developed from the institutional struggle between two stakeholders in a strategic action field.

Plastic waste management in urban areas: Key takeaways from the “Send Plastic Home” project in Bangkok, Thailand

This study evaluates the plastic waste recycling program, named “Send Plastic Home,” tailored for urban areas in Thailand. Thirteen strategically located plastic drop-off points were implemented, and their effectiveness was assessed using the Productivity Index (PI). In-depth interviews and group discussions were conducted to identify key stakeholders and estimate the Social Return on Investment (SROI) associated with the project. Moreover, the environmental impacts of various plastic waste management scenarios were investigated and compared. To improve the PI of drop-off points, pass-through points for smaller amounts of plastic and drive-through points for bulk returns are recommended. Increasing drop-off points in highly populated areas, coupled with effective multi-channel public relations, would be beneficial. The current plastic waste management approach, combining recycling and waste-to-energy methods, yields commendable environmental benefits, particularly in mitigating marine aquatic ecotoxicity. With a collected plastic waste volume of 22,135 kg, greenhouse gas emissions and waste management costs are minimized by 27 tonCO2eq and 1803 USD, respectively. The program operates effectively, as evidenced by an impressive SROI ratio of 8.45. These findings provide a data-driven foundation and actionable insights for the design and implementation of more efficient plastic waste collection infrastructures in urban environments, aligning with the circular economy concept.

Review of Organic Waste-to-Energy (OWtE) Technologies as a Part of a Sustainable Circular Economy

Organic waste-to-energy (OWtE) technologies are playing a steadily increasing role in the Green Transition, thus becoming a powerful driver in the establishment of an ever more efficient and sustainable circular economy. The advantages of OWtE processes are well known: not only do they reduce the waste volumes sent to landfills or incineration plants, but also and foremost, through the energy they yield (biogenic carbon dioxide, amongst others), they reduce dependance on fossil fuels. This article gives a complete panorama of these technologies, starting from the classical methods and ending with a review of the latest modern novelties. Advantages and disadvantages of each method are highlighted, with particular focus on the formation of by-products and the relevant treatment aimed at preventing environmental pollution. Accordingly, modern techniques for increasing waste-to-energy efficiency and integrating the concept of circular economy and substitutability are analyzed from this perspective. Along with an analysis of modern scientific achievements in this area, practical examples of the implementation of technologies in European countries are given, with an emphasis on the obvious advantages, both economic and environmental.

Effective recovery of limonene-rich concentrate from lemon residues using terpene-based deep eutectic solvents based on statistical experimental design.

Waste by-products of the juice industry appear valuable for the circular economy concept, considering that the peel accounts for almost half of the total fruit weight. Therefore, the recovery of these highly valuable components from relevant biowaste has become a very interesting research topic. The current study aims to develop an extraction process integrated with hydrophobic deep eutectic solvent (DES) based on statistical experimental design approach. Homogenizer-assissted extraction (HAE) was used to recover the citrus extract rich in limonene (the main component of the volatile mixture) from lemon peels. Menthol-based deep eutectic mixtures were accompanied by carboxylic acids (formic, acetic, and propionic acids). Optimization continued on the combination that gave the highest efficiency (in terms of limonene content) among the solvents prepared at different molar ratios (1/1, 1/2, and 2/1). Process parameters were analyzed to optimize the process through central composite design with response surface method (RSM). D-Limonene yield was quantified with gas chromatography-mass spectrometry (GC-MS) with solid-phase microextraction (SPME) technique. The quality of the lemon peel extracts was also evaluated with respect to in vitro bioactivity assays (phenolic content and 2,2-diphenyl-1-picrylhydrazyl [DPPH] free radical scavenging activity). The maximum yield (3.80 mg-limonene per g fresh sample) was achieved by 2 mg solid/30 mL DES, ~53 sec, and ~8500 rpm. Statistically most effective variable was identified as solid mass, followed by second powers of mixing speed and extraction time at p< 0.0001.

Are the Undergraduate Students Ready for K-economy?

In this era, the knowledge-based economy (k-economy) is becoming increasingly popular and widely discussed in various circles because it is an economic concept in which knowledge and information are the main factors in generating economic value and creating progress. Students’ k-economy readiness is expected to help students prepare well, one of which is with the accounting education they get. This study uses a quantitative approach that examines the effect of accounting education, students have on k-economy readiness. This study uses an online questionnaire distributed to 150 undergraduate students in East Java, Indonesia. The results of this study showed a positive influence of students’ accounting education on their k-economy readiness. This study can be used as a basis for developing a learning plan or curriculum for high schools and universities, so that the younger generation can prepare well and participate in the K-economy. Keywords: accounting education, k-economy, economics education, undergraduate students, quantitative
