This entry examines how wage-setting institutions (WSIs) shape wages across advanced economies. It focuses on four core mechanisms—minimum wages, collective bargaining, wage coordination, and wage centralization—drawing on theoretical insights, empirical evidence, and cross-country comparisons. The analysis shows that minimum wages safeguard low-paid workers but have heterogeneous employment effects depending on their level and enforcement. Collective bargaining raises average wages and compresses wage inequality, though it can reduce flexibility and create insider–outsider dynamics. Wage coordination stabilizes wage growth, prevents inflationary spirals, and fosters equity, while wage centralization promotes solidarity wages and macroeconomic discipline but may limit adaptability. Using The Organization for Economic Co-operation and Development (OECD) and Institutional Characteristics of Trade Unions, Wage Setting, State Intervention and Social Pacts (ICTWSS) data, the study highlights institutional diversity, ranging from coordinated Nordic models to fragmented liberal systems, and identifies trends toward “organized decentralization”. Policy implications suggest that WSIs should be viewed not as rigidities but as adaptable frameworks that can balance efficiency, equity, and stability when carefully designed. The conclusion emphasizes that the future of wage-setting lies in leveraging institutional complementarities to respond to globalization, technological change, and shifting labor market conditions.

This study provides a comprehensive characterization of the low-to-intermediate sulfidation (LS-to-IS) epithermal Molai Zn-Pb±(Ag,Ge) ore (Vigla-Mesovouni orebody) in Laconia, Greece, and provides insights on how such data may be employed in beneficiation flow-sheet design. Detailed mineralogical, chemical, textural, and physicochemical characterization defines a systematic transition from early refractory Ge-rich to late-stage refractory Ag-rich mineralization, including sulfides and fahlores. Germanium, although present in all sphalerite varieties (Sp-I, Sp-II, and Sp-III), is predominantly enriched in early sphalerite (Sp-I, up to 1891.60 ppm). Interestingly, Ge is also enriched in early Py-I pyrite, with content reaching up to 383 ppm. Silver is mainly concentrated in late-stage tetrahedrite Ttr-II (up to 3.60%), galena (Ga-II), and, to a lesser extent, late sphalerite (Sp-III). Liberation studies reveal effective liberation of Py-I and Sp-I, major Ge carriers, in the coarser fractions (+0.150 mm) and near complete liberation of all ore phases below 0.036 mm. Combined beneficiation via Wilfley pre-concentration and differential flotation produced up to ~35% Pb and ~65% Zn at >85% recovery for the smallest fractions (−0.036 mm). Ore characterization revealed that secondary circuits may be developed to further enhance the economic value of Molai ore (Ge from Py-I, and Ag±[Sb,As] from Ttr-II and Ag-bearing sulfosalts), which are dismissed as wastes in Pb and Zn flotation circuits. The results of our study establish a robust foundation for the design of tailored, multi-stage metallurgical flow-sheets aimed at maximizing the economic value of the Molai epithermal resource.

Assisted reproduction is a rapidly expanding pillar of medical tourism. Greece combines a liberal legal framework, internationally accredited clinics, and comparatively competitive costs, attracting cross-border patients seeking ART services. Following the 2022 amendment (Law 4958/2022) which amends the original law n.3305/2005, treatment is permitted up to age 54 under specific authorization, while court-approved surrogacy, anonymous gamete donation, and the adoption of decision-support technologies (e.g., AI-assisted embryo assessment, PGT-A) underpin the sector’s growth. This review synthesizes legal, medical, economic, and social dimensions, drawing on Q1 literature and official datasets (WHO, OECD, ESHRE/ICMART), and compares Greece with Spain, the USA, the Czech Republic, and Ukraine. Quantitative indicators include age-stratified success rates and indicative treatment costs. We discuss benefits and risks for patients and the health system, highlighting policy options for sustainable, ethically robust reproductive tourism in Greece. Full article

Launched in 2013, China’s Belt and Road Initiative (BRI) was originally devised to link East Asia and Europe through a network of physical and digital infrastructure. This article analyses the BRI’s development in the European context by offering a comparative analysis of 727 BRI and BRI-like projects within 46 European countries from 2005 to 2021. The analysis considers projects’ location, typology, status, and the main enterprises involved in each project. According to our results, there is a “two-speed Europe”. Indeed, while the vast majority of projects are included in the Digital Silk Road (e.g., telecommunication, transfer technology, data centre, 5G, fintech) and are located in North-Western Europe, traditional investments in infrastructure (e.g., ports, roads, railways, SEZ) are concentrated in South-Eastern Europe and the Balkan countries. While North-Western Europe is particularly concerned about cyber security and data protection issues, various South-Eastern European countries look favorably upon the development opportunities offered by the BRI. The BRI is clearly different from the Western approach to development (based on competition and economic liberalism) and integration (based on treaties). The BRI approach—including its platform, leveraging political flexibility, economic pragmatism, ability to mobilize resources, and ability to create synergies between state and business—could take advantage of the flaws of the European integration process. The BRI, with its strengths as well as weaknesses, represents an opportunity for the EU to understand the need for greater economic and political foresight, social cohesion, and economic flexibility to meet the development needs of its member countries. China, too, can draw inspiration from cooperating with EU countries on how to improve the reception of its investment initiatives by focusing on reciprocity, security guarantees, and protection of rights and the environment.

The transformation of energy systems towards low emission is one of the key assumptions of the climate and energy policy of the European Union and many countries around the world. These changes include not only the power and transport sectors but also the heating of residential buildings, which consume significant amounts of energy and emit large amounts of greenhouse gases. This article presents a detailed comparative analysis of the costs of heating using an air-to-water heat pump and a condensing gas boiler. The study concerned a retrofitted single-family building from the 1990s, located in southern Poland. The calculations were made taking into account daily meteorological data for two full heating seasons: 2022/2023 and 2023/2024. This approach made it possible to more precisely reproduce real operating conditions. The study was conducted for various configurations of the central heating system: surface and radiator. The following parameters were also taken into account: (1) variable heat pump parameters, such as supply temperature LWT and coefficient of performance COP; (2) current tariffs for electricity and natural gas; and (3) forecasted tariffs for electricity and natural gas in the conditions of market liberalization and phasing out of protective mechanisms. A comparison of the two heating seasons revealed lower costs with a heat pump. In some cases, the cost of heat generated by a gas boiler was over 100% higher than with a heat pump. This applies to both heating seasons. Under the current tariffs, the calculated gas cost for the first season was PLN 6856 (EUR 1605) (1 EUR = 4.27 PLN) compared to heat pump heating costs ranging from PLN 3191 to PLN 4576 (EUR 747 to 1072). For future gas and electricity tariffs, the costs were PLN 8227 (EUR 1926) for gas and PLN 3841 to PLN 5304 (EUR 899 to 1242) for a heat pump. Similarly, for the second heating season, these values were PLN 6055 (EUR 1418) for gas heating and PLN 2741–3917 (EUR 642–917) for a heat pump under the current tariffs, and PLN 7267 (EUR 1702) and PLN 3307–4540 (EUR 774–1064) under future tariffs. This means percentage savings of between approximately 33% and 55%, depending on the heating type and tariff. Therefore, the obtained results indicate the higher profitability of using an air heat pump compared to a gas boiler. This advantage was maintained in all the discussed scenarios, and its scale depended on the type of installation, supply temperature, and the selected electricity tariff. The highest economic profitability was noted for low-temperature systems. These results can provide a basis for making rational investment and design decisions in the context of the energy transformation of single-family housing. Full article

This study examines the moderating effect of bank capitalization on the relationship between economic freedom and banking performance, offering comparative evidence from both advanced and emerging economies. Using an unbalanced panel of 213 countries from 1993 to 2018, this study applies a two-step System Generalized Method of Moments approach to address dynamic effects, endogeneity, and unobserved heterogeneity. The results show that economic freedom exerts a negative and significant impact on bank profitability (ROA and ROE), particularly in emerging markets with weaker institutional safeguards. Strong internal capital buffers, on the other hand, mitigate these adverse effects and enhance resilience, supporting stable profitability under liberalized conditions. Regulatory capital shows a less consistent and sometimes restrictive role. Disaggregated results indicate that equity buffers most effectively cushion the risks of financial and investment freedom, whereas trade freedom is less sensitive to capital levels. The findings emphasize that successful liberalization depends on institutional capacity and capitalization strength, highlighting the importance of tailored prudential frameworks. The study contributes to debates on financial liberalization, Basel III, macroprudential regulation, and bank risk management, underscoring that a “one-size-fits-all” liberalization strategy may undermine stability and efficiency unless supported by robust capital buffers.

The Building Houses on Rented Land Model (BHRLM) was a pivotal land development model that drove Shanghai’s urbanization in the early modern era. This research examines the spatial generative mechanism of the Prepaid Building Houses on Rented Land Model (PBHRLM), prevalent during 1938–1941. It reveals how the wartime economic environment enabled interest alliances constituted with developers, landowners, and tenants to stimulate urban spatial growth. Firstly, we aim to analyze the features of architectural types linked to the PBHRLM using data-driven methods. Secondly, we aim to apply financial capital theory to investigate the innovations of financing methods. Finally, we draw on speculation theory to establish connections between the features of architectural types and the innovations of financing methods. The results include the following: (1) The PBHRLM’s dominant architectural types—new-styled lane houses, semi-shikumen lane houses, and garden houses—shared low-rise, high-density spatial features. (2) The PBHRLM’s innovations of financing methods lie in its convergence of financing and profitability, reflecting developers’ speculative intent. The research concludes that the PBHRLM operated as a spatial actuarial practice. Through risk games, the developers utilized the model to liberate land development from the control of financial capital and achieved multi-stakeholder synergy, generating small-scale, dispersed land development patterns. At the same time, surging housing demand thus perpetuated architectural types catering to the middle class with low-rise, low-tech tectonics and independent dwelling styles that continued to densely populate Shanghai concessions.

Electrical grids are undergoing a transformation driven by the increasing integration of renewable energy sources on the consumer side. This shift, alongside the electrification of consumption—particularly in areas such as electric mobility—has the potential to significantly reduce CO₂ emissions. However, it is also contributing to a rise in electricity prices due to growing demand and infrastructure costs. Paradoxically, these higher prices serve as a catalyst for further investment in renewable energy technologies by reducing the payback periods of such systems. Recent European legislation has accelerated this transformation by mandating the liberalization of energy markets. This regulatory shift enables the emergence of prosumers—consumers who are also producers of energy—by granting them the right to generate, store, and trade electricity using the existing distribution grid. In this new landscape, photovoltaic systems represent a viable and increasingly attractive investment option for both households and businesses. This study presents an economic evaluation of photovoltaic system investments across different European countries, focusing on key indicators such as payback periods and the impact of local solar irradiation on the resulting electricity price. The analysis provides insight into the varying economic feasibility of distributed solar energy deployment, offering a comparative perspective that supports both policymakers and potential investors in making informed decisions about renewable energy adoption.

This theoretical article explores the contrasting ontologies, axiologies, and political economies of transhumanism and posthumanism. Transhumanism envisions the human as an enhanced, autonomous agent shaped by neoliberal and Enlightenment ideals. Posthumanism challenges this by emphasizing relationality, ecological entanglement, and critiques of commodification. Both engage with technology’s role in reshaping humanity. Drawing on Braidotti’s posthumanism, Haraway’s cyborg figuration, Ahmed’s politics of emotion, Berlant’s cruel optimism, Massumi’s affective modulation, Seigworth and Gregg’s affective intensities, Zuboff’s surveillance capitalism, Fisher’s capitalist realism, Cooper’s surplus life, Sadowski’s digital capitalism, Lupton’s quantified self, Schafheitle et al.’s datafied subject, Pasquale’s black box society, Terranova’s network culture, Bratton’s platform sovereignty, Dean’s communicative capitalism, and Morozov’s technological solutionism, the article elucidates how subjectivity, data, and infrastructure are reorganized by corporate systems. Introducing technogensis as the co-creation of human and technological subjectivities, it links corporate-platform practices to future trajectories governed by Apple, Meta, and Google. These branded technologies function not only as enhancements but as infrastructures of governance that commodify subjectivity, regulate affect and behavior, and reproduce socio-economic stratification. A future is extrapolated where humans are not liberated by technology but incubated, intubated, and ventilated by techno-conglomerate governments. These attention-monopolizing, affective-capturing, behavior-modulating, and profit-extracting platforms do more than enhance; they brand subjectivity, rendering existence subscription-based under the guise of personal optimization and freedom. This reframes transhumanism as a cybernetic intensification of liberal subjectivity, offering tools to interrogate governance, equity, agency, and democratic participation, and resist techno-utopian narratives. Building on this, a posthumanist alternative emphasizes relational, multispecies subjectivities, collective agency, and ecological accountability, outlining pathways for ethical design and participatory governance to resist neoliberal commodification and foster emergent, open-ended techno-social futures.

As a consequence of the gradual exhaustion of apatite ore reserves, intensive comminution has been implemented in mineral processing operations to enhance phosphorus liberation. Consequently, improving the flotation efficiency of fine particles has remained a persistent challenge within the phosphate industry. The performance of flotation columns is strongly affected by the interaction between gas (bubble) and particle. The present research was designed to evaluate how certain process variables and chemical dosages influence gas holdup and its correlation with the column flotation performance of fine particles derived from a low-grade apatite ore. Column flotation experiments were conducted employing a factorial experimental approach to evaluate the effects of air flow rate, surfactant concentration, collector dosage, and depressant dosage on gas holdup, P₂O₅ grade, and recovery. The results made it possible to identify the levels of gas holdup that lead to appropriate values of P₂O₅ grade and recovery simultaneously, and their relation with the operating variables and reagent dosage. Gas holdup values higher than 23.5% led to the desired values of P₂O₅ grade (>30%) and recovery (>60%) simultaneously. Statistical models were developed with high correlation coefficients (R² > 0.98) to predict P₂O₅ grade and recovery as functions of the operating variables. This research provides a comprehensive framework of the gas holdup effect on column flotation systems, offering significant potential for improving the economic viability of low-grade phosphate ore processing.

Trade facilitation in regard to agricultural products plays a critical role in reducing costs and enhancing efficiency, especially in today’s complex global economic environment. The purpose of this study is to empirically examine how trade facilitation measures contribute to sustainable agricultural trade development in the RCEP (Regional Comprehensive Economic Partnership) region, with the aim of providing actionable policy recommendations. This study investigates the impact of trade facilitation on agricultural trade between China and other RCEP members through two complementary approaches—developing a multidimensional evaluation index system and implementing an extended gravity model—both applied to decade-spanning panel data. The results reveal that a 1% improvement in trade facilitation levels increases the volume of agricultural trade by 8.397%, with e-commerce development being the most influential driver. However, stringent customs procedures show counterintuitive negative effects, highlighting unique challenges in agricultural supply chains. As the largest agricultural trader within the RCEP, China should prioritize digital infrastructure investment and multilateral cooperation to address these barriers, thereby advancing regional trade liberalization.

The BRICS countries have been increasingly prioritizing electricity transition as a crucial step towards achieving sustainable growth, energy security, and mitigating climate change. As major emerging economies, the BRICS nations will play a significant role in the global energy landscape since their transition to renewable energy sources holds a significant implication for global energy markets and environmental sustainability. This study investigates the impact of the renewable energy transition on economic growth in BRICS nations from 1990 to 2023, employing a panel NARDL, DOLS, and FMOLS models. This study investigates the relationship between disaggregated renewable energy sources and economic growth. The findings show that renewable energy’s impact on economic growth varies across countries and depends on the type of renewable energy source. Specifically, hydropower, and wind power are found to have significant positive impacts on economic growth in some BRICS countries, while other renewables and trade openness have insignificant impacts. To foster economic growth and the expansion of renewable energy, it is essential for policymakers to focus on investments in hydropower and wind energy. Furthermore, they should encourage trade liberalization, as well as nuclear power development, and enhance regional collaboration. This study offers significant contributions to the current body of literature on the renewable energy–economic growth nexus, supplying crucial insights for both policymakers and researchers.

This paper explores the concept of ephemeral cultural landscapes through the lens of public election advertising during the 2025 Australian Federal election in the regional city of Albury, New South Wales. Framing election signage as a transient cultural landscape, the study assesses the distribution of election signage (corflutes) disseminated by political candidates against demographic and socio-economic criteria of the electorate. The paper examines how corflutes and symbolic signage reflect personal agency, spatial contestation, and community engagement within urban and suburban environments. A detailed windscreen survey was conducted across Albury over three days immediately prior to and on election day, recording 193 instances of campaign signage and mapping their spatial distribution in relation to polling booth catchments, population density, generational cohorts, and socio-economic status. The data reveal stark differences between traditional party (Greens, Labor, Liberal) strategies and that of the independent candidate whose campaign was marked by grassroots support and creative symbolism, notably the use of orange corflutes shaped like emus. The independent’s campaign relied on personal property displays, signaling civic engagement and a bottom-up assertion of political identity. While signage for major parties largely disappeared within days of the election, many of the independent’s symbolic emus persisted, blurring the temporal boundaries of the ephemeral landscape and extending its visual presence well beyond the formal campaign period. The study argues that these ephemeral landscapes, though transitory, are powerful cultural expressions of political identity, visibility, and territoriality shaping public and private spaces both materially and symbolically. Ultimately, the election signage in Albury serves as a case study for understanding how ephemeral landscapes can materially and symbolically shape public space during moments of civic expression.

In comparative analyses, specific features of the Spanish welfare and housing systems have often been emphasized. The case of Barcelona illustrates the extent to which these features are the result of a long-standing historical trajectory and the decisive impact of the challenges and policy responses adopted during Franco’s lengthy, dark, and gloomy regime. This period marked a significant shift, not only due to the persistent shortage of social rental housing, but also because of the early consolidation of a homeownership culture and its dominance in working-class suburban areas—a legacy that is completely different from that of the welfare states of Western Europe. Through a review of the literature and the analysis of primary sources, ongoing research on Barcelona seeks to clarify the factors and processes that led to this transformation, as well as its evolution during the democratic period, within an international context of economic liberalization and the dismantling of the welfare state.

This study investigates the impact of two comminution technologies—Vertical Shaft Impactors (VSI) and High-Pressure Grinding Rolls (HPGR)—on gold flotation performance, using ore samples from the Ballarat Gold Mine, Australia. The motivation stems from the growing need to improve energy efficiency and flotation recovery in mineral processing, particularly under increasing economic and environmental constraints. Despite the widespread use of HPGR and VSI in the industry, limited comparative studies have explored their effects on downstream flotation behavior. Laboratory-scale experiments were conducted across particle size fractions (300–600 µm) using two collector types—Potassium Amyl Xanthate (PAX) and DSP002 (a proprietary dithiophosphate collector) to assess differences in flotation recovery, concentrate grade, and specific energy consumption. The results reveal that HPGR produces more fines and micro-cracks, enhancing liberation but also increasing gangue entrainment and energy demand. Conversely, VSI produces coarser, cubical particles with fewer slimes, achieving higher flotation grades and recoveries at lower energy input. VSI at 600 µm demonstrated the highest flotation efficiency (4241) with only 9.79 kWh/t energy input. These findings support the development of hybrid or tailored comminution strategies for improved flotation selectivity and sustainable processing. Full article
