Against the background of a growing and increasingly sophisticated body of theological literature on economic ethics, this article proposes a project to change for the better, morally, how coffee is supplied on the campuses of Catholic colleges and universities. We argue that this project is squarely in service of a Catholic college or university’s core educational goal of humane development of its students. The article then proceeds in three steps. First, we explain how the coffee supply chain works and how it is entangled in what Pope Francis called “the economy that kills.” Second, we discuss obstacles to our proposed project and a number of strategies for overcoming them. Third and finally, we reflect further on why our project is worth undertaking. Its impetus is resistance to the exploitation of the vulnerable and affirmation of the basic human dignity of the poor. It thereby presents an opportunity to show students Catholic social thought in practice.
We develop a quantitative contraction framework for Schrodinger and Sinkhorn bridges based on transportation-cost inequalities and Riccati matrix difference equations. Our approach combines logarithmic Sobolev and Talagrand-type inequalities to obtain explicit entropy and Wasserstein contraction bounds for Sinkhorn bridge measures, entropic optimal transport plans, and the associated Markov transport maps. A key feature of the analysis is the interplay between transport-cost inequalities and matrix Riccati difference equations arising in filtering and stochastic control. The results are established under local regularity assumptions on the reference transition, formulated in terms of curvature, Lipschitz continuity, and Fisher-information bounds. Within this general setting, we derive quantitative stability and convergence estimates for Schrodinger bridges and Sinkhorn iterates that are robust with respect to the choice of reference measure. As a main application, we specialize the theory to linear-Gaussian reference transitions, where the Gaussian structure permits sharp constants, refined exponential decay rates, and continuity estimates for Schrodinger bridges, Sinkhorn iterates, barycentric projections, conditional covariances, and proximal sampler semigroups. In this setting, we recover and extend several known contraction results for entropic and Wasserstein distances, and obtain new quantitative bounds that improve previously available rates. Our results provide a unified probabilistic framework for stability, regularity, and convergence of Sinkhorn algorithms.

This paper discusses and contains offensive content. Language models (LMs) are used in decision-making systems and as interactive assistants. However, how well do these models making judgements align with the diversity of human values, particularly regarding social and moral norms? In this work, we investigate how inclusively LMs perceive norms across demographic groups (e.g., gender, age, and income). We prompt 11 LMs on rules-of-thumb (RoTs) and compare their outputs with the existing responses of 100 human annotators. We introduce the Absolute Distance Alignment Metric (ADA-Met) to quantify alignment on ordinal questions. We find notable disparities in LM responses, with younger, higher-income groups showing closer alignment, raising concerns about the representation of marginalized perspectives. Our findings highlight the importance of further efforts to make LMs more inclusive of diverse human values. The code and prompts are available on GitHub under the CC BY-NC 4.0 license.
Reliable autonomous driving systems require accurate detection of traffic participants. To this end, multi-modal fusion has emerged as an effective strategy. In particular, 4D radar and LiDAR fusion methods based on multi-frame radar point clouds have demonstrated the effectiveness in bridging the point density gap. However, they often neglect radar point clouds' inter-frame misalignment caused by object movement during accumulation and do not fully exploit the object dynamic information from 4D radar. In this paper, we propose MoRAL, a motion-aware multi-frame 4D radar and LiDAR fusion framework for robust 3D object detection. First, a Motion-aware Radar Encoder (MRE) is designed to compensate for inter-frame radar misalignment from moving objects. Later, a Motion Attention Gated Fusion (MAGF) module integrate radar motion features to guide LiDAR features to focus on dynamic foreground objects. Extensive evaluations on the View-of-Delft (VoD) dataset demonstrate that MoRAL outperforms existing methods, achieving the highest mAP of 73.30% in the entire area and 88.68% in the driving corridor. Notably, our method also achieves the best AP of 69.67% for pedestrians in the entire area and 96.25% for cyclists in the driving corridor.
This paper examines the intricate interplay among AI safety, security, and governance by integrating technical systems engineering with principles of moral imagination and ethical philosophy. Drawing on foundational insights from Weapons of Math Destruction and Thinking in Systems alongside contemporary debates in AI ethics, we develop a comprehensive multi-dimensional framework designed to regulate AI technologies deployed in high-stakes domains such as defense, finance, healthcare, and education. Our approach combines rigorous technical analysis, quantitative risk assessment, and normative evaluation to expose systemic vulnerabilities inherent in opaque, black-box models. Detailed case studies, including analyses of Microsoft Tay (2016) and the UK A-Level Grading Algorithm (2020), demonstrate how security lapses, bias amplification, and lack of accountability can precipitate cascading failures that undermine public trust. We conclude by outlining targeted strategies for enhancing AI resilience through adaptive regulatory mechanisms, robust security protocols, and interdisciplinary oversight, thereby advancing the state of the art in ethical and technical AI governance.
The aim of this article is to elucidate the rational foundations upon which personalist bioethics is built, thereby enhancing understanding regarding its place within the broader discourse of secular bioethics. Personalist bioethics, as a dynamic pursuit, actively engages with scientific discoveries, periodically revisiting them and considering contemporary individualsʼ diverse perceptions of identity and values. It integrates two foundational trunks: personalism and Aristotelian-Thomistic theology with metaphysical reference. The method employed by personalist bioethics is illustrated through triangulation: the exposition of biomedical reality, an in-depth study of anthropological significance, and the identification of values at stake. Rooted in a substantialist concept of the human person, it follows a systematic interaction of various knowledge spheres, aiming not only to describe problematic relations but also to propose prescriptive solutions. Personalism maintains that the human person is valuable for who he is and not only for the choices he makes; he is a source from which the choices proceed. According to personalist ethics, the ethical value of an act will have to be considered under the subjective aspect of intentionality, but it will also have to be considered in terms of its objective content and its consequences. The natural moral law that urges every conscience to do good and avoid evil, therefore, becomes concrete in respect for the human person in all the fullness of his values, his essence, and ontological dignity.

In June 2022, the Catholic Peacebuilding Network hosted Catholic Peacebuilding in Times of Crisis: Hope for a Wounded World, an international virtual conference with Church leaders, scholars, peacebuilding specialists, and other practitioners from more than 30 countries. The intent of the conference was to examine how Catholic peacebuilding can respond in an integral way to the diverse challenges and crises of today. This essay introduces that conference and four essays adapted from it that make up this special symposium. These four symposium essays provide a glimpse of the ways in which Catholic peacebuilding can ask questions of Catholic moral theology and ethics. Some are practical and some theoretical, some are critical and some supplementary. The hope is that they help set the table for additional conversation between these areas of praxis and thought, as the work of moral theologians and theological ethicists is vital for making peacebuilding a living part of the church’s mission.
This article explores and compares two similar debates in Germany and Sweden during the 1980s, in which feminists blamed the Hebrew Bible, or ‘Old Testament’, for being the origin of the patriarchy. In Germany, the psychologist and pedagogue Gerda Weiler articulated the discourse in several writings, which led to a scholarly debate on anti-Jewish tendencies within Christian feminist theology. In Sweden, the debate mainly became a media event, initiated by the author Birgitta Onsell. Instead of criticising the discourse, as in the German debate, other actors reinforced it, for example by highlighting Jesus as a feminist and a contrast to the Old Testament religion. The article further examines ideological consequences of the discourse, including the interdiscursive link to the notion of Judaism as responsible for the patriarchal moral that enabled the Holocaust, also expressed in the public sphere in Germany and Sweden.
This chapter approaches Paul Farmer’s work from the lens of liberation theology in public health, particularly the activism of liberation theologians for universal healthcare coverage in Brazil, stressing health care as a human right. This liberation approach in medicine precedes Paul Farmer’s work. The text presents experiences of liberating approach to health care developed in Brazil that began before Farmer’s activism and scholarship. The author argues that Farmer can be seen as part of this liberation perspective, that he incorporated in his medical service after his reading of earlier Latin American liberation theology’s material. Hence, he brought to the US context (and English readers) a liberation approach to medicine, also present in his public discourse and practice around the world, through his own voice/hands and the actions of the organization he co-founded, Partners In Health. Doing so, Farmer helped to expand the liberation approach to public health, offering a new pluralism that mediates the dialogue between the global and the local.

To achieve desirable performance, current AI systems often require huge amounts of training data. This is especially problematic in domains where collecting data is both expensive and time-consuming, e.g., where AI systems require having numerous interactions with humans, collecting feedback from them. In this work, we substantiate the idea of $\textit{cognitive models as simulators}$, which is to have AI systems interact with, and collect feedback from, cognitive models instead of humans, thereby making their training process both less costly and faster. Here, we leverage this idea in the context of moral decision-making, by having reinforcement learning (RL) agents learn about fairness through interacting with a cognitive model of the Ultimatum Game (UG), a canonical task in behavioral and brain sciences for studying fairness. Interestingly, these RL agents learn to rationally adapt their behavior depending on the emotional state of their simulated UG responder. Our work suggests that using cognitive models as simulators of humans is an effective approach for training AI systems, presenting an important way for computational cognitive science to make contributions to AI.
Striving to be focused and concrete, Silvia de Sanjosé offers a specific example to inform present and future commitments in the ongoing cancer pandemic by articulating a global strategy for eliminating cervical cancer. Cervical cancer, which is preventable, is a global public health problem. It is the fourth most common cancer, with over 600.000 new cases diagnosed every year and it is the fourth leading cause of cancer death in women worldwide. Most of these cancer cases occur in low-resource settings where women are not screened regularly. While highlighting these ongoing challenges, the author stresses the existing opportunities for prevention, screening, and vaccination.
We investigate Kantian equilibria in finite normal form games, a class of non-Nashian, morally motivated courses of action that was recently proposed in the economics literature. We highlight a number of problems with such equilibria, including computational intractability, a high price of miscoordination, and problematic extension to general normal form games. We give such a generalization based on concept of program equilibria, and point out that that a practically relevant generalization may not exist. To remedy this we propose some general, intuitive, computationally tractable, other-regarding equilibria that are special cases Kantian equilibria, as well as a class of courses of action that interpolates between purely self-regarding and Kantian behavior.
Increasing automation in the healthcare sector calls for a Hybrid Intelligence (HI) approach to closely study and design the collaboration of humans and autonomous machines. Ensuring that medical HI systems' decision-making is ethical is key. The use of Team Design Patterns (TDPs) can advance this goal by describing successful and reusable configurations of design problems in which decisions have a moral component, as well as through facilitating communication in multidisciplinary teams designing HI systems. For this research, TDPs were developed to describe a set of solutions for two design problems in a medical HI system: (1) mitigating harmful biases in machine learning algorithms and (2) sharing health and behavioral patient data with healthcare professionals and system developers. The Socio-Cognitive Engineering methodology was employed, integrating operational demands, human factors knowledge, and a technological analysis into a set of TDPs. A survey was created to assess the usability of the patterns on their understandability, effectiveness, and generalizability. The results showed that TDPs are a useful method to unambiguously describe solutions for diverse HI design problems with a moral component on varying abstraction levels, that are usable by a heterogeneous group of multidisciplinary researchers. Additionally, results indicated that the SCE approach and the developed questionnaire are suitable methods for creating and assessing TDPs. The study concludes with a set of proposed improvements to TDPs, including their integration with Interaction Design Patterns, the inclusion of several additional concepts, and a number of methodological improvements. Finally, the thesis recommends directions for future research.
Scepticism towards childhood vaccines and genetically modified food has grown despite scientific evidence of their safety. Beliefs about scientific issues are difficult to change because they are entrenched within many related moral concerns and beliefs about what others think. We propose a cognitive network model which estimates the relationships, dissonance, and randomness between all related beliefs to derive predictions of the circumstances under which beliefs change. Using a probabilistic nationally representative longitudinal study, we found support for our model's predictions: Randomness of the belief networks decreased over time, for many participants their estimated dissonance related positively to their self-reported dissonance, and individuals who had high estimated dissonance of their belief network were more likely to change their beliefs to reduce this dissonance. This study is the first to combine a unifying predictive model with an experimental intervention and sheds light on dynamics of dissonance reduction leading to belief change.
We propose a new solvable class of multidimensional quantum harmonic oscillators for a linear diffusive particle and a quadratic energy absorbing well associated with a semi-definite positive matrix force. Under natural and easily checked controllability conditions, the ground state and the zero-point energy are explicitly computed in terms of a positive fixed point of a continuous time algebraic Riccati matrix equation. We also present an explicit solution of normalized and time dependent Feynman-Kac measures in terms of a time varying linear dynamical system coupled with a differential Riccati matrix equation. A refined non asymptotic analysis of the stability of these models is developed based on a recently developed Floquet-type representation of time varying exponential semigroups of Riccati matrices. We provide explicit and non asymptotic estimates of the exponential decays to equilibrium of Feynman-Kac semigroups in terms of Wasserstein distances or Boltzmann-relative entropy. For reversible models we develop a series of functional inequalities including de Bruijn identity, Fisher's information decays, log-Sobolev inequalities, and entropy contraction estimates. In this context, we also provide a complete and explicit description of all the spectrum and the excited states of the Hamiltonian, yielding what seems to be the first result of this type for this class of models. We illustrate these formulae with the traditional harmonic oscillator associated with real time Brownian particles and Mehler's formula. The analysis developed in this article can also be extended to solve time dependent Schrodinger equations equipped with time varying linear diffusions and quadratic potential functions.
The author discusses the health effects of pollution and climate change to planetary health, and examines the distribution of their impacts through the lens of social justice. Pollution is the largest environmental cause of disease, disability, and death–whether one considers pollution in air, oceans, and soil or caused by chemicals. At the same time, global climate change has numerous negative effects on the planet’s ecosystems, and multiple adverse effects on human health are enhanced by pollution. Furthermore, both pollution and climate change disproportionately affect the poor and the vulnerable–and, among them, children and people living in the Global South and in poor communities worldwide. Hence, pollution, poverty, poor health, and lack of social justice are closely intertwined.
This article explores the theological themes prevalent in the language of anorexia nervosa by briefly exploring extant literature in the field before reporting on the author’s qualitative fieldwork with Christian women with anorexia nervosa. Sufferers, both those from religious and non-religious backgrounds, often convey their understanding of their illness in theological and moral language, using terms such as ‘sin’ and ‘sacrifice’. The use of theological frameworks on ‘Pro-Ana’ internet forums is also considered. The article concludes by considering the implications of this use of theological language for pastoral and chaplaincy care, and argues that highly skilled mental health chaplains would be of benefit to treatment models for anorexia nervosa and that community church leaders can pay a crucial role in long-lasting recovery, particularly for anorexic women who profess a Christian faith.
Within the wider field of ethical reflection and moral theology, Reformed ethics is tasked with understanding and orienting human action theologically by formative reference to the fundamental description of moral reality provided by Reformed doctrine. The essential features of this moral reality can helpfully be displayed and coordinated around the themes of belonging, gratitude, law, and holiness. Consideration of these themes helps to bring out what is distinctive in a Reformed theological ethic in the midst of much that is evidently also held in common with the wider Christian tradition. As this chapter looks to demonstrate, the history of Reformed theological ethics testifies to the fundamental and abiding conviction on the part of Reformed believers and theologians that reformatio doctrinae is intrinsically bound with and finds it term in serious and joyful reformatio vitae.
