Employee participation as a new frontier in corporate social responsibility: a review of the literature

PurposeThis paper examines the relationship between employee involvement in decision-making (in particular codetermination) and corporate social responsibility, i.e. extra-financial or environmental, social and governance (ESG) performance.Design/methodology/approachLiterature review was done based on the following methodology: synthesis of existing knowledge, bringing together and summarising published work on the relationship between codetermination and CSR; identification of potential gaps in the literature, highlighting what has been little studied in the field; assessment of the quality, relevance and limitations of existing studies and following citation standards to acknowledge the work of other researchers.FindingsCodetermination has a rather positive impact on extra-financial performance. The special status of employee directors, who combine independence (from management) with knowledge of the company and its sector, may generate better strategic choices and enhanced oversight of management action, with positive consequences for ESG performance overall. Regarding, more specifically, governance, although codetermination inevitably upsets the internal balances of corporate boards, it does not seem to pose a major risk to their operation. The possibility of blocking decisions remains theoretical, and codetermination does not necessarily lead to oversized boards. On the social side, codetermination would have a positive impact on wage and employment management. Finally, regarding the environment, no strong consensus has emerged so far on whether codetermination improves or deteriorates corporate environmental performance.Originality/valueThe originality of our approach is to propose a review of the literature on the determinants and impact of employee participation in light of concerns and reflections on the nature and responsibility of firms, particularly about the ecological and environmental crisis that contributed to shifting the challenges to less operational and more strategic considerations. We thus question how the participation of employees in the decision-making process tends to delineate a democracy that is no longer merely liberal but also “social”. We examine, conceptually and empirically, the various forms that the participation of employees may take and their impact on firm performance.

Plasmon‐Promoted Interatomic Hot Carriers Regulation Enhanced Electrocatalytic Nitrogen Reduction Reaction

AbstractUtilizing hot carriers for efficient plasmon‐mediated chemical reactions (PMCRs) to convert solar energy into secondary energy is one of the most feasible solutions to the global environmental and energy crisis. Finding a plasmonic heterogeneous nanostructure with a more efficient and reasonable hot carrier transport path without affecting the intrinsic plasmonic properties is still a major challenge that urgently needs to be solved in this field. Herein, the mechanism by which plasmon‐promoted interatomic hot electron redistribution on the surface of Au3Cu alloy nanoparticles promotes the electrocatalytic nitrogen reduction reaction (ENRR) is successfully clarified. The localized surface plasmon resonance (LSPR) effect can boost the transfer of plasmon hot electrons from Au atoms to Cu atoms, trigger the interatomic electron regulation of Au3Cu alloy nanoparticles, enhance the desorption of ammonia molecules, and increase the ammonia yield by approximately 93.9 %. This work provides an important reference for rationally designing and utilizing the LSPR effect to efficiently regulate the distribution and mechanism of plasmon hot carriers on the surface of heterogeneous alloy nanostructures.

Educating in and for Degrowth: Training Future Generations to Prevent Environmental Collapse

This research has been developed through a literature review on the importance of and current approach in the education system to the present environmental and ecosystemic crisis and the training of future generations in degrowth in the Spanish education system. To this end, a systematic literature review (SLR) has been carried out following the standards of the PRISMA declaration. In total, 40 articles published between January 2005 and March 2024 were selected from the following databases: Scopus, Dialnet, Web of Science and Scielo. The findings show it is a relevant topic in school education as a concern, but it is not reflected in educational practice; that it has been incorporated into the curriculum, but sporadically, decontextualised and more focused on ‘sustainable development’; also, it lacks critical questioning of the unlimited growth and consumption model that capitalism entails. The study concludes that it is crucial to incorporate degrowth in a transversal way in education at all schooling levels, and to reform the curricula of the faculties of education in all universities so that the pedagogy of degrowth is a priority in the training of future teachers.

Fabrication of CdIn2S4/ZnS S-scheme heterojunction via in-situ phase transformation for boosting photocatalytic conversion of organic compounds

Developing efficient photocatalysts is one of green and low cost tactic for addressing the environmental deterioration and energy crisis. Therefore, it remains a fantastic and important strategy to design an efficient junction between different semiconductors for harvesting solar light, boosting the redox capability. Herein, the fabrication of ZnS in situ decorated CdIn2S4 (referred to as CIS-Zx) were prepared by converting ZnS particles on Cd2In4S surface by a facile cation exchange method during solvothermal synthesis. According to a series of PEC measurements and DFT calculations, the bending of band edge as well as the establishing of built-in electric field in the interface of CIS/ZnS heterojunction were concluded, causing the formation of in-situ S-scheme heterojunctions in CdIn2S4/ZnS. The in-situ S-scheme heterojunctions can effectively ameliorate the migration behaviors of photo-generated charges. Compared with pure CdInS4, ZnS and physically mixed CdIn2S4/ZnS, the CIS-Zxin-situ S-scheme heterojunction exhibits efficient photocatalytic activity and stability in the selective reduction of aromatic nitro compounds and oxidation of aromatic alcohols, it is hoped that this work will open up a new avenue for innovative applications of in-situ S-scheme heterojunctions.

In situ composite of biomass derived carbon/porous carbon nitride and its enhanced performance in solar-driven photocatalytic hydrogen evolution reaction

Converting waste organic biomass into functional carbon materials is regarded as a sustainable development strategy to address environmental pollution and energy crisis. In this work, carbon/porous carbon nitride (PCN) composite photothermal catalysts were prepared via an in-situ method with urea and phragmites spikelets as raw materials for the solar-driven hydrogen evolution reaction (HER). The biomass derived porous carbon, in close contact with PCN, not only acts as a charge transfer bridge facilitating the rapid separation and migration of photogenerated charges but also serves as a photothermal carrier to enhance the kinetic process of the photocatalytic reaction. Under simulated solar irradiation (AM 1.5 G), the optimal HER rate of the composite catalyst is 4.98 mmol g−1h−1, which is 2.1 times that of pure PCN. The physicochemical properties of the materials, including morphology, crystal structure, elemental composition and state, and energy band characteristics, were determined. Additionally, theoretical calculations were employed to explore the impact of biomass-derived porous carbon on the electronic structure and band structure of carbon nitride. This work not only broadens the range of raw materials for biomass-derived porous carbon but also provides a novel strategy for promoting photocatalytic HER through synergistic multifield effects, showing broad application prospects in the field of resource recovery and green catalysis.

Social determinants of participation in genetic research among Puerto Ricans and in the Puerto Rican diaspora

Puerto Ricans are underrepresented in genetic research. This underrepresentation denies Puerto Ricans the benefit from therapeutic developments that could mitigate health disparities arising from conditions for which genetically-derived treatments exist. The Puerto Rican diaspora, especially post-2017 due to economic and environmental crises, has expanded within the USA. Prior research suggests that Latin American diaspora communities are less likely to participate in genetic research. We hypothesized, specifically, that the Puerto Rican diaspora in the USA would be less likely to participate in genetic research than would Puerto Ricans in their homeland's archipelago, and that accounting for social and cultural determinants related to the diaspora experience would mitigate this disparity. We implemented an analytical cross-sectional study of archipelago-residing Puerto Ricans and of the USA-residing diaspora to evaluate this hypothesis. With 1582 Puerto Ricans (723 in Puerto Rico, 859 in the USA), we found that while most participants would participate in genetic research, participation rates varied significantly by diaspora status. Puerto Ricans born and living in the USA were initially more likely to decline participation compared to those in Puerto Rico (OR = 1.54, p < 0.01). However, once adjusted for social and cultural variables, this difference was eliminated (aOR = 1.08, p = n.s.). The factors influencing non-participation include oppression, discrimination, distrust, and social determinants, aligning with the theory of minoritization. An important community in the USA and in the world, Puerto Ricans have the right to participate in well-conducted research and to benefit from its findings, particularly around topics that could help address existing disparities in health outcomes.

MIL-125-PDI/ZnIn2S4 Inorganic-Organic S-Scheme Heterojunction With Hierarchical Hollow Nanodisc Structure for Efficient Hydrogen Evolution from Antibiotic Wastewater Remediation.

Efficient photocatalytic production of H2 from wastewater is expected to address environmental pollution and energy crises effectively. However, the rapid recombination of photoinduced carriers results in low photoconversion efficiency. At present, inorganic-organic S-scheme heterojunction have become a prominent and promising technology. In this study, an organic ligand modified MIL-125-PDI/ZnIn2S4 (ZIS) inorganic-organic S-scheme heterojunction catalyst is designed. ZIS nanosheets are grown on the disc-shaped MIL-125-PDI surface to form a distinctive hollow nanodiscs with hierarchical structure, giving the material an abundance of surface active sites, an optimized electronic structure, and a spatially separated redox surface. Consequently, the optimal 100MIL-125-PDI250/ZIS exhibited high photocatalytic HER of 508.99 µmol g-1 h-1 in Tetracycline hydrochloride (TC-HCl) solution. Meanwhile, the catalyst achieved complete TC-HCl removal and mineralization rate of 66.62% in 4h. Experimental and theoretical calculations corroborate that the staggered band alignment and work function difference between MIL-125-PDI and ZIS induce the formation of a built-in electric field, thus regulating the charge transfer routes and consequently enhancing charge separation efficiency. The possible photocatalytic mechanism is analyzed using liquid chromatography-mass spectrometry (LC-MS), and the toxicities of the degradation products are also evaluated. This work presents a green dual-function strategy for H2 production and antibiotic wastewater recycling.

Constitutive Modeling of Anisotropic Plasticity with ML Algorithms in Metals

Nuclear reactors hold significant promise for mitigating the environmental crisis and achieving a carbon-free world. The advancement of nuclear technology, however, is intricately tied to the materials used in reactors, with metals and alloys forming their core components. Understanding the plasticity and degradation of these materials is crucial to prevent critical reactor failures caused by factors such as radiation-induced embrittlement, creep, and fuel-cladding interactions. While traditional plasticity modeling has relied on constitutive laws and yield functions, the advent of machine learning (ML) and artificial intelligence has opened new avenues for this field. This paper explores the potential of data-driven approaches to enhance plasticity modeling for metals used in nuclear reactors. Recent studies have leveraged ML algorithms, including support vector machines and artificial neural networks, to model yield surfaces and correct theoretical yield functions with experimental data. Despite their accuracy, these models often lack interpretability and generality. To address these challenges, we investigate the applicability of various ML algorithms, i.e. neural networks, logistic regressions, decision trees, K-nearest neighbors, and Gaussian processes (GPs), in developing data-oriented flow rules for plasticity modeling. The paper demonstrates the superiority of GPs in terms of interpretability and generality. Using stress data generated from PyLabFEA, we compared the performance of these algorithms, highlighting the intrinsic uncertainties associated with GP predictions. Our findings indicate that Gaussian process classifiers (GPCs) offer a promising approach for modeling plasticity in metals, providing a balance between precision and physical insight. Additionally, this work presents a deep neural network (DNN) to model anisotropic Hill-type plasticity with perfect test data accuracy (accuracy score: 1.0), which is often hard to achieve with a classification problem. This shows the superiority of DNNs in terms of accuracy in modeling yield functions. The implications of our results for bridging the scale gaps in macrolevel simulations are discussed, and future directions for incorporating microstructural features into ML-based plasticity models are proposed. Overall, the ML framework presented in this paper can be employed for modeling constitutive relations that can be incorporated within traditional Finite Element Method (FEM)–based codes. Specifically, the GPC or DNN developed in this work can be readily swapped with the yield function within the so-called return mapping algorithm of nonlinear FEM-based plasticity subroutines to indicate yielding. Consequently, this merging of ML and FEM will allow us to leverage the geometric representational ability of FEM alongside the superior modeling capabilities of the ML algorithms.

Refugee Rights and International Law: Evaluating the Efficacy of Global Humanitarian Responses to Forced Displacement

The increasing scale of forced displacement due to conflict, persecution, and environmental crises has brought refugee rights to the forefront of global humanitarian discourse. This article critically examines the efficacy of international law in protecting refugee rights and assessing global responses to the growing refugee crisis. Through an analysis of key international legal frameworks, such as the 1951 Refugee Convention and the role of the United Nations High Commissioner for Refugees (UNHCR), the study evaluates the adequacy of current policies in addressing the challenges faced by refugees. It highlights gaps in protection, such as unequal burden-sharing among nations, restricted access to asylum, and prolonged displacement in refugee camps. Case studies from various regions reveal how inconsistent application of international law undermines refugees’ access to fundamental rights, including safety, healthcare, and education. The article argues for stronger international cooperation, better policy implementation, and more robust legal mechanisms to ensure the protection of refugee rights. It concludes by offering recommendations for improving global humanitarian responses and creating more equitable and sustainable solutions for forced displacement.

An unlikely form of violence: conservation and conflict in the Chilean mountains

ABSTRACT This article explores the relationship between legal frameworks, mountain communities and the puma in Chile. Delving into the effects of how pumas’ lives have been reshaped by myriad factors (economy, the law, and global change), we address the question of how ‘killability’ is distributed in one Chilean basin where the species is endangered: the Maule. We pay attention to a three-level relationship that distributes and sets the rules around the right to maim and kill bodies, encompassing the state's, rancher's and puma's intrusions. We explore the distribution of the ‘killable’ as ongoing effects and actions cast upon bodies. These actions shape interspecies and life-death ecological relationships. We continue by deepening into the contextual vulnerability of human and non-human lives forced to compete, or set new agreements, to improve and rearrange state mandates, experiencing the symptoms of an environmental and political crisis in which they must either endure or perish. Finally, we address how the interplay between economy, conservationism and animal lives redistribute the value of, and grievability among, species.

An integrated management system (IMS) approach to sustainable construction development and management

Construction is significantly contributing to the severe environmental crisis it is facing. The sector consumes over 3 billion tons of raw materials annually, and its activities account for 40% of global CO2 emissions. Traditional integrated strategies toward fragmented sustainability cannot offer total optimization. In this respect, the present research presents an integrated management system (IMS) containing a composite of metrics for sustainable construction management (SCM). This research was specifically geared to test the relationship between the elements of IMS and SCM from the perspective of the construction industry. A quantitative survey tested through 119 professionals was used for data collection. It is established through structural equation modeling (SEM) that the internal consistency of Cronbach’s Alpha 0.72–0.95 and construct validity was strong. The Fornell-Larcker criterion was realized to affirm good discriminant validity. Crucial results identified the presence of significant impacts for quality management (QM) (β = 0.643, p < 0.001), risk management (RM) (β = 0.53, p < 0.001), and safety management (SM) (β = 0.439, p < 0.001). Therefore, this study further enhances the scalability of IMS so that it is practically applied to improve project quality and safety, along with risk management. Future research could also focus on studying the context of the integration of IMS with SCM and continue to work using objective performance measures to validate these findings.

The Current State and Future of the Urban Cold Chain: A Review of Algorithms for Environmental Optimization

Cold chains are essential in providing people with food and medicine across the globe. As the global environmental crisis poses an existential threat to humanity and societies strive for more sustainable ways of life, these critically important systems need to adapt to the needs of a new era. As it is, the transportation sector as a whole accounts for a fifth of global emissions, with the cold chain being embedded in this old fossil-fuel-dependent infrastructure. With the EU is passing regulations and legislation to cut down on emissions and phase out polluting technologies like combustion engine vehicles, the next couple of decades in Europe will be defined by rapid infrastructural change. For logistics and cold transportation, this shift presents many opportunities but also highlights the need for innovation and new research. In this literature review, we identify pressing issues with the current urban cold chain, review the recent research around environmental optimization in urban logistics, and give a cross-section of the field: what the trending research topics in urban logistics optimization across the globe are, and what kind of blind spots are identifiable in the body of research, as well as changes arising with future green logistics infrastructure. We approach the issues discussed specifically from the point of view of refrigerated urban transportation, though many issues extend beyond it to transportation infrastructure at large.

Conspiratorial Storytelling and Environmental Crisis

ABSTRACT What happens when the narrative of conspiracy theory is used to represent the ecological crisis? Among climate scientists, conspiracy theories are often considered harmful, because they spread doubt about the global scientific consensus on climate change. In recent years, however, the rhetoric of conspiracy theory has become increasingly common among environmental filmmakers who use its narrative conventions to tell stories about complex environmental issues. This article explores this trend by analysing the Netflix documentary, Seaspiracy (2021), which portrays the oceanic crisis as the result of global corruption. The article demonstrates how the film’s high narrative velocity, its negotiation of individual agency, and its construction of ‘hierarchies of scale’ create an ambiguous depiction that is both overwhelming and reductive, yet also highly engaging and, potentially, empowering. Reflecting on this ambiguity, the article argues that this emergent subgenre provides insights into our shifting relations with the ecological crisis and its representational challenges.

Heterointerface of Monodispersed Ultrathin-MnO2@Amorphous Carbon to Attain Durable Lattice Oxygen Redox Chemistry through Creation of Dual Lattice Oxygens.

Lattice oxygen (OL) redox chemistry is a key to alleviating the energy and environmental crisis, but it faces challenges in activating the OL while ensuring structural stability. We disclosed herein that engineering a heterogeneous interface between ultrathin oxide and amorphous carbon can attain the durable OL redox chemistry without introducing catalytically impure sites. To this end, we proposed a green strategy to grow ∼3.9 nm-thickness wrinkled δ-MnO2 nanosheets that are rich in defects and are vertically aligned on amorphous carbon spheres. Experiments and calculations reveal that the electrons can easily migrate from the amorphous carbon to MnO2 at the δ-MnO2@C heterointerface. The heterogeneous interfaces can not only regulate the Mn-O bond and create oxygen defects in δ-MnO2 but also introduce lattice oxygen with varying reactivities. Specifically, the δ-MnO2@C structure carries more activated lattice oxygen that contributes to the enhanced activity on catalytic oxidation of bioderived 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA), with a high FDCA formation rate of 1759 μmol gcat-1 h-1 and a high selectivity of 95%. The heterogeneous interface of MnO2@C also brings inert lattice oxygen, so that it manifests high structural stability during the oxidation reactions. This work deepens the fundamental understandings in the engineering of lattice oxygen for durable lattice oxygen redox chemistry and showcases an effective interface technique in creating advanced catalysts for clean sustainable energy.

A primer of community ecology using the R language

AbstractCommunity ecology beginners often struggle to understand theories expressed in complex mathematical formulas and to master computer programming. To remedy this situation, this article provides a practical, R‐based introduction to community ecology by illustrating core concepts (vital rates, carrying capacity, density dependence) and models that can be used to explore the patterns of species abundance and diversity. The structure of this article consists of three modeling exercises, each asking a general question that can be answered by a combination of theory and R programming: (1) what determines the abundance of species, and what makes a population persist and go extinct?; (2) what determines the distribution of species and species diversity?; (3) what determines the relative abundance of species and what allows species to coexist? Through the exercises, I discuss the following five concepts and ideas that provide valuable insights into the questions: (i) the tragedy of the commons, (ii) the theory of island biogeography, (iii) competitive exclusion, (iv) the neutral theory of biodiversity, and (v) frequency dependence. These materials are thus designed to guide the reader in developing an intuition for ecological thinking that will help capture the essence of the global environmental and biodiversity crisis. Although this article does not delineate the scope and depth of the vast field of community ecology, I hope that it will motivate the reader to step up to a more formal introduction to community ecology.

Cultural Sensitivity and Social Well-Being in Embassy Architecture: Educational Approaches and Design Strategies

Over the past two decades, the expanding environmental and ecological crises highlight the need to broaden the concept of sustainability to encompass support for cultural sensitivity and social well-being. This study explores the role of architectural education in fostering cultural sensitivity and social well-being in embassy architecture within a framework of environment–behavior studies. It starts from the premise that the architectural values of a culture are deeply rooted in the relationship between the users, architecture, and surrounding environment. State-sponsored architectural works (e.g., embassies, consulates, cultural centers) built outside the country are viewed as symbolic representations of a nation’s diplomatic and cultural influence. These architectural typologies hold a unique potential to act as bridges for cross-cultural dialogue and foster a collective sense of global citizenship. In order to develop and assess the teaching curriculum, a specific assignment was given to master’s students of the Faculty of Architecture, University of Belgrade, with the aim to explore how engineering education can be adopted to motivate students toward sustainable attitudes and design solutions. While traditional diplomatic architecture emphasizes inward-facing, fortress-like design strategies, establishing physical and symbolic barriers between the embassy’s territory and the surrounding context, this research advocates for a more holistic approach oriented toward cultural sustainability, openness, and integration within an urban context. Key findings highlight creative solutions for balancing cultural representation with functional requirements while prioritizing community engagement, environmental responsibility, and user well-being. By demonstrating the two distinctive architectural strategies, this study contributes to the culturally responsive embassy design within the broader context of sustainable architectural education.

Evaluating Belizean Sugarcane Farmers’ Adoption Intentions Regarding Organic Fertilizer

Sugarcane is vital to Belize’s economy, significantly contributing to its Gross Domestic Product and supporting a large portion of the population. It is necessary to address the declining soil health in this nation due to excessive chemical fertilizer use, and Belize aims to promote organic fertilizers, which enhance soil quality and reduce environmental impacts. The primary purpose of this study was to investigate the determinants of adoption intentions regarding organic fertilizers among Belizean sugarcane farmers using the Extended Theory of Reasoned Action. Data were collected from 207 farmers in the Orange Walk and Corozal districts using a non-probability sampling approach via a self-administered questionnaire measuring perceived health risks, environmental concerns, attitudes, subjective norms, and adoption intentions. The results revealed that both perceived health risks and environmental concerns influenced farmers’ attitudes and subjective norms, which, in turn, affected their adoption intentions, as revealed through path analysis; socio-economic factors, years of farming experience, and ownership background partially affected adoption intentions regarding organic fertilizers, as determined via binary logistic regression analysis. The findings suggest that raising farmers’ awareness of health risks and environmental crises, as well as enhancing farmers’ knowledge and their positive attitudes towards the use of organic fertilizers, will contribute to the sustainable development of the sugarcane industry in Belize. Some interventions by policymakers are recommended to support the transition to the use of organic fertilizers in sugarcane farming.

Why Are We Not on the Road to Save the Earth and Us? Indirect Drivers of the Anthropogenic Impacts on Environment

The growth of anthropogenic impacts on environment rapidly acelerated since 1950s and led to overshooting of several planetary ecological thresholds, decreasing the Earth´s ability to support our civilization. Even the concept of sustainability did not lead to recognition of necessary limits to this growth. These limits define the framework of our study on the roots of the current environmental crisis. Numerous studies have been devoted to environmental degradation, but analyses of its indirect driving forces are often fragmentary and confusing. We have attempted to provide a systemic assessment of three groups of indirect drivers by reflecting new physical ones and adding the paradigmatic drivers – such as the mechanical heritage and low reflection of life´s awesome complexity. A paradigm shift is required, as the current paradigm is incompatible with the reality of the Earth´s life support systems erosion. We also strived to contribute to much debated value-based category analysis. This underlines complexity of the driving forces of the crisis. Moreover, some absurd theories of how to come out of the crisis were mentioned. We stress the opportunity for Christians to put into practice the biblical messages to become caring stewards of nature in the God´s image.

Hierarchically fibrillated spunlaced nonwovens from waste wool supported ionic liquid as solid amine adsorbents for CO2 capture

The environmental crisis caused by excessive emissions of carbon dioxide-based greenhouse gases has garnered widespread public concern. Solid amine is considered to be one of the most effective carbon dioxide (CO2) adsorbents. However, traditional solid amine carriers have problems such as structural collapse, low efficiency and poor regeneration. In this study, waste wool having hierarchical fibrous structure was spunlaced, fibrillated and later compounded with amino acid ionic liquids (AAIL) leading to the formation of the AAIL@feather-like wool nonwoven absorbents. A synergistic co-amine effect was observed after primary and secondary fibrillation without any sacrifice in the mechanical property of wool nonwovens. Also, the fibrillated nonwovens had high specific area which provided high loading rate (13.53 %) on AAIL. Compared with untreated wool nonwovens, the CO2 adsorption capacity of feather-like wool nonwovens was higher by 65 % (11.75 mmol/g) after loading AAIL. Furthermore, the CO2 adsorption capacity was retained (95.2 %) even after 12 cycles at 80 ℃, indicating that the AAIL@ feather-like wool nonwovens possess good long-term stability. This work paves the way for large scale manufacturing of biobased solid adsorbents with a hierarchical nonwoven structure for efficient CO2 capture.
