The concept of ‘marketplace of ideas’ has been employed as a conventional argument to justify freedom of expression. The Constitutional Court of Korea has also been significantly influenced by this concept, presenting it as a rationale to protect freedom of expression and asserting that “the Internet is the medium most closely approximating the ‘marketplace of ideas’”. However, the proliferation of disinformation, hate speech, and the development of artificial intelligence have urged a re-evaluation of the validity of the ‘marketplace of ideas’, which posits that truth can prevail over falsehoods through unrestricted competition. ‘Marketplace of ideas’, which is advocated from a laissez-faire perspective, also encounters challenges related to market failure when examined from an economic perspective. This phenomenon occurs because market failure is not limited to the market for goods but extends to the market for ideas as well. In the context of freedom of expression, market failure can result in impediments to information distribution, insufficient dissemination of high-quality information, and democratic representation. To address market failure in the realm of free expression, it is imperative to focus on platform governance. In the United States, self-regulation by individual companies or industries, and in Europe, co-regulation by governments, have been proposed as potential solutions to market failure. The divergence between the US and European approaches to platform governance stems from the distinct constitutional traditions of freedom of expression. While platform governance mechanisms, such as self-regulation and co-regulation, offer advantages including flexibility, expedience, and professionalism, they may also generate tensions with the rule of law and potentially result in private censorship when limiting fundamental rights. To ensure the democratic legitimacy of self-regulation, limitations on freedom of expression must be implemented in a manner consistent with the rule of law. Furthermore, to prevent co-regulation from devolving into private censorship, considerable caution must be exercised to ensure that government intervention does not transform into censorship by administrative authority.

사회약자층 안전도 제고방안 : 민간-경찰 협력시스템을 중심으로

The issue of vulnerable populations in South Korea has been a longstanding concern, with various attempts made to address it over the years. However, these efforts have not yielded satisfactory outcomes. On the contrary, the problem has intensified quantitatively and qualitatively, becoming a more entrenched social issue. The lack of visible progress can be attributed to the structural problems of the national economy. At the same time, there is a limitation in the fragmented approach of addressing the issues of vulnerable populations solely from an economic perspective. The category of vulnerable populations includes not only those facing economic challenges but also socially and culturally marginalized groups, as well as individuals with illnesses or disabilities who are unable to lead lives within the normal range of society on their own. These groups are being perpetuated and expanded under the neglect of the state and society. Thus, resolving the issues faced by vulnerable populations must focus on enhancing social safety measures to improve their quality of life. To achieve this, it is essential to establish a safety system tailored to each type of vulnerable population and create an environment where this system can operate effectively. Specifically, this involves setting up dedicated departments within police forces, strengthening patrol functions for identifying and detecting vulnerable groups, and building a civil-police cooperation safety system. In addition, there should be continuous training of specialized personnel to care for these populations, along with the establishment of support systems to assist them. Fundamentally, the need to enhance the cohesion among disbanded community members is to ensure a comprehensive community safety net.

A comparison of animal and plant-based proteins from an economic, environmental, and nutritional perspective in the Republic of Ireland

CONTEXTProtein is a central component of health and nutrition. The current protein production system is unlikely to sustainably meet the growing global demand for protein. Therefore, alternative sources of protein must be considered. OBJECTIVEThis study uniquely compares animal-based (milk, beef meat, sheep meat) and plant-based (cereals and legumes) protein production in terms of land usage. The comparison is carried out across a suite of economic, environmental, and nutritional metrics. As land use decisions are taken at the farm level, the analysis adopts a farm gate approach. Focusing on the supply side, consumption is not considered in the analysis. METHODSEconomic performance is measured through the gross and net margins. Environmental performance is evaluated through farm-level greenhouse gas (GHG) emissions and nutrient (nitrogen and phosphorus) balances. Nutritional performance is measured through the gross protein yield, the protein yield corrected for digestibility and land-use efficiency, i.e., the land needed to generate one kg of (digestible) protein. Results are expressed per hectare and per 100 g of gross and digestible protein to allow for a holistic comparison. The analysis focuses on the Republic of Ireland, a relevant country given the importance of the strong agricultural export focus, the dominance of the livestock sector and the country's ambitious environmental emission reduction targets. RESULTS AND CONCLUSIONSFindings indicate that, on a per hectare basis, milk production on dairy farms has the strongest economic performance and highest GHG emissions amongst the products considered. Crops' gross and net margins are less than half that of dairy farms, but they also show the strongest environmental performance generally. Cereals and legumes have the best nutritional performance, from a protein perspective, whereas sheep meat production returned the lowest gross and digestible protein yields per hectare. Arable crops also show the lowest GHG emissions and nutrient balances on a per unit of protein basis. SIGNIFICANCELand-use policies need to be designed holistically, given the complexity of the agricultural sector. Agricultural policy design currently focuses on income support and on the environmental impact of the agricultural sector, but farmers' livelihood and food and protein security need to be safeguarded. Diversifying agricultural production and increasing plant-based protein production in Ireland, a country with a livestock-focused agricultural sector, could contribute to achieving the climate change targets of the country, provided the necessary policy levers are in place.

Balancing Environmental Sustainability and Economic Viability in Luxembourgish Farms: An Agent-Based Model with Multi-Objective Optimization

To curb the impacts arising from the agricultural sector, the actions undertaken by policymakers, and ultimately by the farmers, are of paramount importance. However, finding the best strategy to reduce impacts, and especially assessing the effects of the interactions and mutual influence among farmers, is very difficult. To this aim, this paper shows an application of an agent-based model (ABM) coupled with life cycle assessment (LCA), which also includes multi-objective optimization of farming activities (including both crop cultivation and livestock breeding) from an economic and environmental perspective. The environmental impacts are assessed using the impact assessment scores calculated with the Environmental Footprint 3.0 life cycle impact assessment method and the study is conducted “from cradle to farm gate”. The model is applied to all the farms in Luxembourg, whose network is built utilizing neighborhood interactions, through which a parameter known as farmer’s green consciousness is updated at each time step. The optimization module is instantiated at the end of each time step, and decision variables (the number of livestock units and land allocation) are assigned based on profitability and specified environmental impact categories. If only profit optimization is considered (i.e., when farmers’ green consciousness is de-activated), the results show a 9% reduction in the aggregated environmental impacts (obtained as the Environmental Footprint single score) and a 5.5% increase in overall profitability. At the farm level, simulations display a clear trade-off between environmental sustainability and financial stability, with a 25% reduction in overall emissions possible if farming activities are carried out using the single score impact in the objective function, though this results in an 8% reduction in profitability over 10 years.

The Stakeholders Engagement Study in Rural Development Program

Rural development is integral to achieving sustainable development in Indonesia, where success is measured from an economic, social, and environmental perspective. As a region with cultural riches and abundant natural resources, the Special Region of Yogyakarta has become a focal point in village development efforts. One example of successful village development is in Kulwaru Village, where communal cattle were constructed. This research aims to explore the role and engagement of stakeholders in village development in the case of communal cattle. This study uses a qualitative case study method by collecting data through in-depth interviews with 15 informants, including local government, group leaders, community leaders, community organizations, and other related organizations. The data was then analyzed descriptively, and a power and interest matrix was used to determine the role positions of the stakeholders. This research found that stakeholder engagement has different powers and interests. Stakeholders included in the categories (1) Key players: administrators, livestock group members, and BKM Bina Mandiri; (2) Keep Informed: Kubaweta Cooperative, Puskeswan, IAAS UGM, and Academics. (3) Keep Satisfied: Kulwaru Village Government, District Agriculture and Food Service. Kulon Progo, the Central and Provincial PUPR Ministries; and (4) monitor category, the PUPR District Service. Kulon Progo. Collaboration between these stakeholders plays a vital role in the success of building communal cattle and surviving and overcoming the slum environment problems faced by the people of Kulwaru Village.

Influence of TEMPO on preparation of softwood nanofibrils and their hydrogel network properties

From an economic and environmental perspective, the use of less chemicals in the production of cellulose nanofibrils (CNFs) is advantageous. In this study, we investigated the oxidation (TEMPO/NaClO2/NaClO, pH 6.8) of softwood (SW) particles with varying amounts of TEMPO (16, 8 or 0 mg g−1 of wood). Following, TEMPO-oxidized SW nanofibrils (TO-SWNFs) were obtained by nanofibrillation and their size, morphology, and crystallite size were assessed. Hydrogel networks of TO-SWNFs were prepared and mechanical properties were measured in dH2O and phosphate buffered saline (PBS) to compare their performance for possible biomedical applications such as wound dressings. The results reveal that the presence of TEMPO is of importance for TO-SWNF network properties, presenting higher eq. H2O absorption (≈2500 %) and elongation at break (≈10 %) with good wet strength (≈180 kPa). In addition, a decrease in use of TEMPO catalyst from 16 to 8 mg g−1 of wood is possible, without detrimental effects on hydrogel network properties (dH2O absorption ≈ 2000 %, elongation at break ≈ 13 %, wet strength ≈ 190 kPa) related to applications as wound dressings.

A Review of Research on Employee Incentive Mechanisms and Firm Performance from the Perspective of Behavioral Economics

This paper reviews the relationship between employee incentives and corporate performance from the perspective of behavioral economics. As the limitations of traditional material incentive theory gradually emerge, behavioral economics provides new theoretical support for the optimization of incentive mechanisms. This paper first explores the core concepts of behavioral economics, including loss aversion, intrinsic motivation, framing effects and social norms, and compares them with traditional incentive theories. By analyzing the additions and modifications of behavioral economics to incentives, it reveals how it affects incentive design, which in turn improves employee motivation and corporate performance. In addition, this paper demonstrates the successful application of behavioral economics principles in corporate incentives by combining practical cases and discusses the marginal effects and potential problems of incentives. Finally, this paper summarizes the effectiveness of the application of behavioral economics in the design of incentives and proposes directions for future research, such as personalized incentives, long-term incentive effects, cross-cultural research and technology-driven incentive design. The study shows that by scientifically designing incentive mechanisms, companies can more effectively motivate employees, improve overall performance, and achieve long-term sustainable development.

Accelerating decarbonized economic growth through net-zero entrepreneurship: Low-carbon economic development perspective

Net-zero entrepreneurship is a novel concept introduced in the context of carbon neutrality, and exploring whether it can catalyze decarbonized economic growth is a worthy pursuit. This study constructs a comprehensive, low-carbon endogenous economic growth model to scrutinize the intricate nexus between net-zero entrepreneurship and decarbonized economic growth. Empirical validation employs a series of multiple regression models to rigorously test the hypotheses derived from the theoretical framework using an extensive dataset spanning Chinese provinces. The results reveal a nuanced landscape. (i) Net-zero entrepreneurship plays a remarkable role in promoting decarbonization growth, with considerable regional heterogeneity. (ii) Green technology progress exhibits a notable mediating effect. (iii) Environmental regulation and industrial structure optimization have positive moderating effects. (iv) The results passed alternative dependent variable and one-phase lag regression robustness tests. In a distinct contribution to entrepreneurship literature, this study augments the discourse on strategies to steer low-carbon transitions. The research findings indicate that net-zero entrepreneurship can accelerate the global decarbonization process, and green technology progress is a significant driving mechanism in this process. Additionally, it is essential to strengthen environmental agencies’ regulatory oversight and optimize industrial structures to pave the way for transformative sustainable growth. In the future, more entrepreneurs should be encouraged to engage in green technology and business model innovation to contribute to global decarbonization efforts.

1H-NMR, HPSEC-RID, and HPAEC-PAD Characterization of Polysaccharides Extracted by Hydrodynamic Cavitation from Apple and Pomegranate By-Products for Their Valorization: A Focus on Pectin

Several chemical analytical methods were applied to characterize the chemical structure of polysaccharides extracted from discarded apples and pomegranate peels using hydrodynamic cavitation methods in a circular economy perspective. In particular, the purity of the polysaccharides and the degrees of acetylation and methylation were evaluated by proton Nuclear Magnetic Resonance (1H-NMR) analysis; simple sugars and galacturonic acid were analyzed simultaneously by High-Performance Anion Exchange Chromatography—Pulsed Amperometric Detector (HPAEC-PAD); the molecular weight of the extracted polysaccharides was determined by High-Performance Size Exclusion Chromatography-Refractive Index Detector (HPSEC-RID). The results showed a negligible presence of co-precipitated proteins/tannins, easily removed by dialysis, as well as other co-precipitated molecules such as monosaccharides and organic acids. Polysaccharides from apples consisted mainly of pectic material with a prevalence of homogalacturonans. Polysaccharides from pomegranate peels showed greater compositional variability with significant amounts of arabinose and galactose, a lower content of pectin, and the presence of rhamnogalacturonans I. Both polysaccharides were highly methylated and differed in the degree of acetylation, which could lead to different properties. Polysaccharides from apples presented two main molecular weights (>805 kDa and 348–805 kDa, respectively), while those from pomegranate peel showed a major fraction at 348 kDa and minor fractions < 23 kDa. In conclusion, the research tools proposed by this study have allowed defining the macrostructure of polysaccharides in a quick and efficient way to valorize these food by-products.

Clinical strategy study on prenatal screening and diagnostic model for Down syndrome

Exploring efficient and easily implementable prenatal screening strategies aims at birth defect prevention and control. However, there have been limited economic evaluations of non-invasive prenatal screening (NIPS) strategies in China. Furthermore, these studies were predominantly confined to local or geographically proximate provinces and lacked universality and representativeness. This study assesses the health economics of current prenatal screening strategies and NIPS as first-line screening programs, analyzing their efficacy to determine an optimal strategy. From the perspective of health economics, cost-effectiveness, cost-benefit, and single-factor sensitivity were conducted for five different screening strategies using a decision tree model. Among pregnant women aged < 35 years who underwent only one screening for foetal Down syndrome (DS), the detection rate, false positive rate and positive predictive value of NIPS for foetuses with DS were superior to those of the other four serological screening methods. Although applying NIPS as first-line screening method yields the highest efficacy and benefits, it currently lacks cost-effectiveness when compared to serological screening and sequential NIPS screening strategies.

Research on the Cultivation of Innovative Talents for Professional Undergraduate Finance Majors from the Perspective of Digital Economy

Along with the arrival of the digital economy, the country’s financial industry ushered in the development of the “golden period,” under this background financial services, technology and others continue to optimize and perfect. To meet the needs of social development, the relevant positions need a large number of high-quality, skilled financial professionals, but the current personnel training model has been unable to achieve the established goals. Therefore, in the context of the new era, vocational colleges need to deeply analyze the new requirements of the digital economy on the ability of professional talents, then discuss the restrictive factors existing in the current training of professional talents, and put forward effective reform measures to improve the quality of talent training and effectively deepen the reform of professional teaching.

Comparative environmental and economic assessment of emerging hydrometallurgical recycling technologies for Li-ion battery cathodes

The growing demand for electric vehicles has led to a growing concern for battery recycling, particularly for critical raw materials. However, there is insufficient investigation into the environmental and economic impacts of hydrometallurgical recycling methods. In this study we explored emerging hydrometallurgical technologies in economic and environmental perspective to establish conceptual routes to recover Co, Ni and Mn oxides from waste LiNi0.33Mn0.33Co0.33O2 cathode materials from spent Li-ion batteries. After, life cycle assessment and costing techniques were utilized to compare the environmental and economical performances of each conceptual route. Recovery efficiency of metal oxides through each route was also considered as a key factor. Results suggested that deep eutectic solvent-based leaching produces the highest impact under many impact categories while electrolysis-based leaching showed the least. Under purification technologies assessed, ion-exchange based purification showed significantly lower impact under many categories except stratospheric ozone depletion. Solvent based purification has been identified as the worst technology for purification. Hydroxide based calcination has been identified as the most environmentally sustainable calcination method compared to oxalate calcination. The route consists with inorganic leaching, ion-exchange based purification and hydroxide calcination showed the lowest environmental impact (emission effect at 33.8 kg CO2 eq), with lower economic impact ($ 119) and the highest recovery efficiency (78 %) per 1 kg of cathode active materials. However, using electrolysis-based leaching can slightly increase the impacts with lower recovery efficiency (75 %) and better economic performance ($104/kg of cathode active materials). Terrestrial ecotoxicity was identified to be the most affected impact category for the recovery processes. It is recommended that technologies like deep eutectic solvent-based leaching, solvent extraction and environmentally sustainable technologies like supercritical fluid extraction need further studies prior to industrial applications.

Spatial-temporal evolution and drivers of ecological sustainability of coastal fisheries in China

Marine fisheries are an important source for the survival and economic livelihood of the world's population. With coastal economic development, rapid population growth, and advances in fishing technology, oceans and coastal areas have been placed under greater environmental pressure. Therefore, the sustainability of coastal fisheries must be revisited. This study used the 3D ecological footprint (EF) model and partial least squares (PLS) to analyze the spatial-temporal evolution of the ecological sustainability of coastal fisheries in China, and discuss the direct and indirect impacts of drivers from economic, social, and technological perspectives. Results showed that the gap between per capita EF and per capita biocapacity (BC) of coastal fisheries narrowed until it stabilized from 2010 to 2020. Footprint depth and size wholly showed a fluctuating upward trend. In terms of spatial distribution, footprint depth was high in the north and low in the south, and footprint size was a relatively scattered. Consumption pull had the largest effect on the ecological sustainability of coastal fisheries in China, followed by the economy push, but the effect of technology suppression was not significant. Some policy recommendations for sustainable fisheries governance were proposed in terms of consumption structure transformation, fisheries industry upgrading, and ecosystem-based management. This study indicated that the current development of coastal fisheries in China is sustainable from an ecological supply and demand perspective. The findings provide information on effective coastal fisheries governance and broad coastal and ocean management, and have the potential to provide references for sustainable fisheries governance in other coastal countries with similar contexts.

Integrating life cycle assessment and multi criteria decision making analysis towards sustainable cocoa production system in Indonesia: An environmental, economic, and social impact perspective

Sustainable Cocoa production practices should be investigated comprehensively to address sustainability requirements and mitigate Cocoa production issues in Indonesia. This study aims to identify the sustainable Cocoa production system considering the environmental, economic, and social impacts. Life cycle framework and multicriteria decision-making (MCDM) were integrated to obtain the study's objectives by comparing Cocoa monocropping system (CM) and Cocoa intercropping systems (IC). The result indicated that in the environmental sustainability aspect, the monocropping system (CM) showed higher performance as indicated by the lower environmental impact in all indicators; for example, CM emitted a lower Global Warming Potential (GWP) that has a lower margin of 34.5–55.9 % compared to the intercropping system (IC-I and IC-II). In the economic aspect, both on the short-term and long-term analysis, the Cocoa intercropping system (IC-II) generated higher value-added and economic feasibility, with a higher profit margin of 150–205 % compared to CM and IC-1. Along with the increase of economic benefits in IC II, this system also significantly provides social benefits, as presented by the higher social index margin of 4.9–23.7 % compared to other systems. Furthermore, by applying decision-making analysis, the result determines the highest index on the Cocoa intercropping system II (IC-II). These findings highlight that applying the intercropping system II is recommended to overcome the cocoa issue at the farmer and decision-maker levels. Additionally, the proposed method that combined LCA-MCDM can be applied to another agricultural commodity to achieve sustainable agriculture production.

Environmental–economic total factor productivity of vegetable production in China from the life cycle perspective

Enhancing agricultural green total factor productivity (GTFP) is crucial for promoting sustainable economic development. However, the absence of systematic approaches to assess the environmental-economic productivity from a full life cycle perspective hinders sustainable agricultural development and constrains the transition to a green economy. This study introduced an innovative framework of life cycle GTFP (LCGTFP) through interdisciplinary collaboration. This framework integrated regionalized life cycle impact assessment (LCIA), multimedia LCIA-based life cycle costing analysis, and the epsilon-based measure combined with the global Malmquist–Luenberger approach. This integration allows for the inclusion of comprehensive environmental burdens into GTFP analysis. Empirical results from the production of 10 types of vegetables in China reveal a “win–win” trend in vegetable industry from an environmental–economic perspective. The LCGTFP reached a value of 1.036 (CV: 0.021) over the past decade, indicating a 3.6% increase in environmental–economic productivity. However, challenges (e.g., fertilizer overuse and regression on the technical frontier) persist in sustainable vegetable production. This study highlights the necessity of technical dissemination, agricultural education, high-quality crop varieties, and e-commerce. Furthermore, the development of the vegetable industry must incorporate environmental and economic conditions, because environmental–economic misallocation occurs in areas that are recognized as having geoclimatic–locational advantages.

Constructing Highly Efficient Catalysts for the 1‐Butene Epoxidation

AbstractEpoxides are high‐valued intermediates in the production of chemicals, pharmaceuticals, perfumes, and polymers. Given the growing demand for epoxides, it is imperative to develop more environmental friendly and sustainable routes instead of the chlorohydrin process. Notably, the direct utilization of hydrogen peroxide (H2O2) for the epoxidation reaction presents significant advantages from both environmental and economic perspectives. The review provides insights into both homogeneous and heterogeneous catalysts employed in the 1‐butene epoxidation using the green oxidant H2O2. Among the diverse range of catalysts, titanosilicate‐1 (TS‐1) has garnered extensive attention due to its exceptional selectivity and high oxygen atom utilization. The aim of this review is to illustrate various strategies for TS‐1 catalysts preparation that can lead to more versatile, higher‐performance, and greener epoxidation processes. Additionally, various potential approaches to enhance the catalyst performance of TS‐1 are highlighted, including (i) constructing specific coordination modes of Ti sites, (ii) regulating the microenvironment around Ti sites, and (iii) improving the accessibility of Ti sites. Furthermore, advances in molding TS‐1 catalysts are also introduced from the perspective of the industrialization. Finally, future research directions are discussed with emphasis on the application scope of TS‐1 to gain deeper insights into epoxidation process.
