Australia II: A Case Study in Engineering Ethics

Australia II became the first foreign yacht to win the America's Cup in 1983. The boat had a revolutionary wing keel and a better underwater hull form. In official documents, Ben Lexcen is credited with the design. He is also listed as the sole inventor of the wing keel in a patent application submitted on February 5, 1982. However, as reported in New York Times, Sydney Morning Herald, and Professional Boatbuilder, the wing keel was in fact designed by engineer Peter van Oossanen at the Netherlands Ship Model Basin in Wageningen, assisted by Dr. Joop Slooff at the National Aerospace Laboratory in Amsterdam. Based on telexes, letters, drawings, and other documents preserved in his personal archive, this paper presents van Oossanen’s account of how the revolutionary wing keel was designed. This is followed by an ethical analysis by Martin Peterson, in which he applies the American NSPE and Dutch KIVI codes of ethics to the information provided by van Oossanen. The NSPE and KIVI codes give conflicting advice about the case, and it is not obvious which document is most relevant. This impasse is resolved by applying a method of applied ethics in which similarity-based reasoning is extended to cases that are not fully similar. The key idea, presented in Peterson’s book The Ethics of Technology (Peterson, The ethics of technology: A geometric analysis of five moral principles, Oxford University Press, 2017), is to use moral paradigm cases as reference points for constructing a “moral map”.

Why you shouldn’t serve meat at your next catered event

Much has been written about the ethics of eating meat. Far less has been said about the ethics of serving meat. In this paper I argue that we often shouldn’t serve meat, even if it is morally permissible for individuals to purchase and eat meat. Historically, the ethical conversation surrounding meat has been limited to individual diets, meat producers, and government actors. I argue that if we stop the conversation there, then the urgent moral problems associated with industrial animal agriculture will go unsolved. Instead, we must also consider the important but overlooked role that midsized institutions play in addressing major collective problems. I focus mostly on the harms that industrial animal agriculture inflicts on humans, animals, and the environment, but the discussion bears on other global issues like climate change. Institutional choices are an underexplored avenue for driving social change—their power and influence outstrip individual actions, and they can shape behavior in modest ways that promote social goods. Here I highlight the paradigmatic case of catered events and suggest three ways that institutional actors can reduce meat consumption and shape cultural attitudes surrounding meat: large impact decisions, subtly shaping incentives, and consolidating burdens.

Perfection and Success

According to reductivist axiological perfectionism about well-being (RAP), well-being is constituted by the development and exercise of central human capacities. In defending this view, proponents have relied heavily on the claim that RAP provides a unifying explanation of the entries on the ‘objective list’ of well-being constituents. I argue that this argument fails to provide independent support for the theory. RAP does not render a plausible objective list unless such a list is used at every stage of theory development to shape the details of the view. Absent such motivated fine-tuning, RAP even fails to provide a satisfying account of two supposed paradigm cases of perfectionist value: achievement and knowledge. Thus, if RAP is to be defended, it must be defended directly by providing reasons for accepting the axiological principle at its heart. It cannot be defended, indirectly, by pointing to its attractive implications.

Modeling dynamic crack growth in quasicrystals: Unraveling the role of phonon-phason coupling

In this work, we employed the phase-field fracture (PFF) model for dynamic brittle fracture in quasicrystals (QCs). The dynamic PFF formulation is derived using both elastodynamics and elasto-hydrodynamic theory. The temporal discretization is achieved using an implicit generalized-α method, which is unconditionally stable for a particular choice of constants. The model incorporates two distinct crack driving forces: (a) the contribution of elastic strain energy from both phonon and phason fields and (b) the contribution solely from the elastic energy associated with the phonon field. To validate the implementation of QCs, we have conducted benchmarking against recent results in the literature, particularly in the context of quasi-static loading. We addressed various paradigmatic case studies to demonstrate the dynamic crack nucleation and propagation in planar 2D decagonal QCs, with a primary emphasis on understanding the interplay between phonon and phason fields. Phason walls, representing low-energy crack paths resulting from atomic rearrangements, play a significant role in crack propagation by introducing an additional energy component. Notably, increasing the phonon-phason coupling constant expedites both crack initiation and propagation. Furthermore, variations in the phonon-phason coupling parameter result in different crack trajectories, observed in both uniaxial and biaxial loading scenarios.

Marketisation and the Public Good: A Typology of Responses among Museum Professionals

Across Western democracies, the public sector has undergone significant changes following successive waves of marketisation. Such changes find material expression in an organisation’s logic and associated vocabulary. While marketisation may be adopted, a growing body of research explains how it is often resisted as public sector professionals reject its logic and vocabulary. We contribute to this debate by detailing additional, theoretically important responses. Rather than simply rejecting or adopting both the logic and vocabulary of marketisation, this article shows how UK museum professionals decouple these. Our analysis shows how museum professionals either fashion generic market vocabulary (e.g. customer, value) to pursue local projects or sustain terms such as public and culture to cling to longer-standing ideals of publicness. Partly because of the nature of cultural goods, we propose the museum sector as a paradigm case to illustrate this phenomenon, but our argument has broader implications for the public sphere.

Future prospects for partially ionized solar plasmas: the prominence case.

Partially ionized plasmas (PIP) constitute an essential ingredient of our plasma universe. Historically, the physical effects associated with partial ionization were considered in astrophysical topics such as the interstellar medium, molecular clouds, accretion disks and, later on, in solar physics. PIP can be found in layers of the Sun's atmosphere as well as in solar structures embedded within it. As a consequence, the dynamical behaviour of these layers and structures is influenced by the different physical effects introduced by partial ionization. Here, rather than considering an exhaustive discussion of partially ionized effects in the different layers and structures of the solar atmosphere, we focus on solar prominences. The reason is that they represent a paradigmatic case of a partially ionized solar plasma, confined and insulated by the magnetic field, constituting an ideal environment to study the effects induced by partial ionization. We present the current knowledge about the effects of partial ionization in the global stability, mass cycle and dynamics of solar prominences. We revise the identified observational signatures of partial ionization in prominences. We conclude with prospects for PIP research in prominences, proposing the path for advancing in the prominence modelling and theory and using new and upcoming instrumentation. This article is part of the theme issue 'Partially ionized plasma of the solar atmosphere: recent advances and future pathways'.

Rastros documentales de la (des)aparición de cuerpos: inhumaciones irregulares y antropología forense en un cementerio público de Córdoba

This article reflects on the extensive use of irregular burials in public cemeteries as a method of disappearance/elimination of bodies during the last civic-military dictatorship in Argentina. Drawing on a historical-anthropological perspective, it investigates a paradigmatic case: the discovery of one of the largest mass graves in Latin America, located in the San Vicente Cemetery in the city of Córdoba, Argentina. The underlying assumption guiding the analysis is that irregular burial involved the intervention of bureaucratic-administrative instances linked to the regular handling of corpses—hospitals, morgues, and public cemeteries—resulting in the existence of documentary traces that currently account for its use and extent. The article begins with the description of a letter written in 1980 by morgue workers and a newspaper article about the first identification in Córdoba, serving as temporal markers of a lengthy search process. The geographical and historical reconstruction of San Vicente and its burial practices configure it as a territory of marginalities and impurities, as a receiver of bodies of the sick, the poor, and also “subversive delinquents.” Analyzed as cultural artifacts, the morgue's entry books and the 1980 letter reveal different aspects of the irregular burial practice and how the bodies of the murdered were incorporated into the routines of state agencies. Such records were crucial in the forensic anthropological work of searching for and locating the large mass grave. The article is framed among studies focusing on the “legal” and “administrative” forms of state repression and terror. It seeks to highlight the importance of preliminary investigation and interdisciplinarity in the application of forensic anthropology, not only in the analyzed geographical area but also in clarifying the multiple violences that permeate the region.

‘Post-fascism’, or how the far right talks about itself: the 2022 Italian election campaign as a case study

ABSTRACT While the mainstreaming of the far right is attracting growing scholarly interest based on its contemporary relevance, the role that far-right self-representation strategies play in this process has seen limited engagement. In this article, we argue that far-right actors employ a post-fascist logic to bring their ideas closer to the mainstream. This logic rests on a dual message, whereby they attempt to outwardly distance themselves from fascism while at the same time recontextualising fascist ideas. To explore these dynamics, we use a mixed-methods approach to discourse analysis to examine far-right social media posts during the 2022 Italian general election. Taking all Facebook, Instagram and Twitter posts during the official campaigning period from the party and leader accounts of Lega per Salvini Premier and Fratelli d’Italia, we explored articulations of the post-fascist dyad within this context. Our findings underscore how both far-right parties ridiculed accusations of fascism and depicted themselves as ‘centre-right’, yet they commonly used fascist dog-whistles and violent anti-immigration discourse to construct a broader conspiracy narrative and portray themselves as Italy's saviour. While Italy proves a paradigmatic case, this research has wider implications for the need to explore the relationship between self-representation and mainstreaming.

Unveiling the magic of mega-city block environments: investigating the intriguing mechanisms shaping children's spontaneous play preferences.

This study delves into the spatial preferences of children for play spaces within high-density urban block environments, specifically targeting the area of Baihua Second Road in Shenzhen, China. Recognizing the critical role of play in children's development, and the unique challenges posed by dense urban settings, this research employs multiclass logistic regression models and negative binomial regression models to construct a detailed mathematical analysis of neighborhood spatial elements and children's play space preferences. Data was meticulously gathered through both objective observations of 14 different types of spaces within the block, and subjective assessments via children's responses to a series of environment photos, capturing the essence of over 3,000 child participants' interactions and choices. Key findings reveal a pronounced preference among children for soft facility features and visually appealing spatial experiences, suggesting a nuanced understanding of play space needs beyond traditional playground designs. Notably, the study identifies that while cartoon-style designs in play facilities might increase moderate attractiveness, ordinary designs hold broader appeal, indicating a preference for diversity in play space aesthetics. These insights offer profound implications for urban planners and designers, advocating for a child-centered approach in the creation of urban play environments that prioritize aesthetic diversity, and the integration of natural elements. Moreover, the study situates Baihua Second Road as a paradigmatic case, illustrating the methodology and analytical framework applied in addressing the complex interplay between children's play preferences and urban spatial configurations. By incorporating a comprehensive data-driven analysis, this research contributes significantly to the discourse on child-friendly urban design, offering valuable strategies for cultivating inclusive and engaging urban play spaces for children amidst the constraints of high-density city living.

Conformism, Ignorance & Injustice: AI as a Tool of Epistemic Oppression

Abstract From music recommendation to assessment of asylum applications, machine-learning algorithms play a fundamental role in our lives. Naturally, the rise of AI implementation strategies has brought to public attention the ethical risks involved. However, the dominant anti-discrimination discourse, too often preoccupied with identifying particular instances of harmful AIs, has yet to bring clearly into focus the more structural roots of AI-based injustice. This paper addresses the problem of AI-based injustice from a distinctively epistemic angle. More precisely, I argue that the injustice generated by the implementation of AI machines in our societies is, in some paradigmatic cases, also a form of epistemic injustice. With a particular focus on AIs employed as gatekeepers of our epistemic resources, this paper shows how their epistemically conformist behaviour is responsible for the marginalisation and the ostracism of minoritarian perspectives. Because it clarifies key structural flaws and weaknesses of current AI design, this paper helps make headway in critical discussion of current AI technologies. And because it forges new theoretical tools to understand forms of epistemic oppression, this paper also contributes to the advancement of feminist theorisation.

Acute Cerebellitis or Post-Infectious Cerebellar Ataxia? Approach to Paradigmatic Pediatric Clinical Cases

Acute cerebellitis is a rare disease resulting from dysfunction of the cerebellum or its connections, with infectious or inflammatory causes, varied clinical manifestations, and evidence of predominantly cerebellar inflammation on magnetic resonance imaging (MRI). It belongs to the spectrum of acute post-infectious cerebellar ataxia, a self-limited disease whose therapeutic approach is individualized. Three clinical cases of cerebellar ataxia in pediatric age are described. In case 1, there is a post-infectious context associated with Epstein-Barr virus. In case 2, there is a possible Mycoplasma pneumoniae post-infectious context, with MRI revealing cerebellar inflammation. Steroids were used in both cases. Case 3 presents severe cerebellar post-infection symptoms associated with varicella zoster virus, and human immunoglobulin was given. Evolution was favorable in all. These cases demonstrate the variable spectrum of post-infectious cerebellar ataxia and the different therapeutic options used, depending on the clinical presentation and individual characteristics of affected children.

‘We really enjoyed doing the extracurricular transmedia stuff’: How I Met Your Mother and the beginnings of transmedia in the sitcom genre

The sitcom How I Met Your Mother (2005–14) applies a narrative with a transmedia perspective, using advertising techniques that had been unusual for its genre up to that point. We refer to the reverse product placement tool as a technique to expand the narrative in a ground-breaking way through books apparently written by one of the characters in the series. This study explores the communicative dimensions applied by its developers through an exploratory-descriptive methodology that offers a qualitative analysis. We conduct a bibliographic study alongside an exclusive interview with the co-creator of the series, Carter Bays. Consequently, our study dissects the communicative process from a semantic and advertising perspective with an international reach. Finally, the results identify a paradigmatic case that takes advantage of the communicational context to build a transmedia narrative, giving rise to an intertextual and parasocial interpretation.

The Life and Times of Turnspit Dogs: A Paradigmatic Case of Animal Labor in Early Modern Industrial Production

Abstract This article investigates the early modern history of dog labor in small-scale industrial production in Europe and the Americas as a paradigmatic example of the history of animal labor. The turnspit dog was the “product” of material conditions of production as they were forced to labor in butter-churning, knife-grinding, water-raising, sewing, and food industries. Furthermore, their bodies and labor tried to be “perfected” by selective breeding and violent methods of training, mechanical dressage, and labor discipline. The incorporation of dog labor into mechanized industrial production developed hand-in-hand with certain ideas, ideologies, and mentalities, such as the mechanistic interpretation of bodies deprived of soul, mind, and sentience.

A statistical analysis of causal decomposition methods applied to Earth system time series

Causal Decomposition (CD) constitutes a novel and widely accepted method for discovering and quantifying the internal causal relationships inherent to complex systems. This new causality bases not on time nor state. Instead, it relies on instantaneous phase coherence between the corresponding Intrinsic Mode Functions (IMFs) of the signals, obtained via Empirical Mode Decomposition (EMD). In this paper we compare the results obtained with two noise-assisted methods: Ensemble EMD (EEMD) and Noise Assisted Multivariate EMD (NA-MEMD). Given the inherent stochastic nature of noise-assisted methods, CD was treated as a randomized experiment. Hence, we repeated procedures to perform a robust statistical analysis. Confidence intervals, adequate normality conditions and differential causality hypothesis testing were then evaluated. The methodology was adjusted through the paradigmatic case of a forced mechanical oscillator, since the causal implications are known in advance. CD was then applied to a couple of series from the Earth system: insolation and oxygen isotope rate. Differential causality was established in favor of insolation at the frequency corresponding to the obliquity cycle. The apparent causality detected with EEMD on other time scales was discarded and attributed to a mode mixing problem. Therefore, NA-MEMD outperformed EEMD with less mode mixing and sharper mode alignment.

The “Global” Deception: Flat-Earth Conspiracy Theory between Science and Religion

The article focuses on flat earthism, one of the most well-known contemporary conspiracy theories in popular culture. According to proponents of this theory, which has found a growing international following in recent years, political institutions such as the U.S. government and scientific institutions such as NASA would operate to deceive humanity about the real shape of our planet and the universe in which we live. In countering the data acquired by modern science and common sense knowledge, flat earthism stands as a heterodox theory and a radical critique of the authority of socially legitimized epistemic institutions. This article consists of two parts. The first part will offer a genealogical reconstruction of the flat-earth conspiracy, tracing its history from the 19th century to the exponents of the current movement. The second part will delve into the discourse of the proponents of flat earthism with specific reference to the Italian context, through documentary analysis of recent publications and online material available on YouTube and Telegram, which constitute some of the main channels for the discussion and dissemination of flat earthism in Italy today. On the basis of the data collected and analyzed, it will be shown how flat earthism represents a paradigmatic case of superconspiracy, that is, of a far-reaching theory capable of linking and including within itself a set of other, more circumscribed theories. To this end, flat earthism elaborates on a discourse that ambivalently combines two registers, scientific and religious language, proposing itself as a dissident narrative that if on the one hand rejects the knowledge of institutionalized and organized science and religion, on the other hand accredits an alternative and anti-intellectualist path of knowledge, accessible to the “common man” that aims to create a space of autonomy and opposition to the processes of secularization and globalization in which the flat earthers see the project of building a dystopian New World Order.

Constitutional interpretation and populism: A comparison between Italy and Hungary

AbstractThis essay aims to compare the constitutional interpretation techniques used by the Italian Constitutional Court and the Hungarian one, facing the advancing of populist claims in Europe. After introducing the differences between the exercise of sovereignty in constitutional legal systems towards populistic regimes, the authors analyse some paradigmatic cases in which Constitutional Courts reacted to populistic waves. Through comparing the different legal instruments adopted to interpret the Constitution, this paper will therefore test the Italian and Hungarian legal system's concrete democratic evolution.

Stochastic resetting with refractory periods: pathway formulation and exact results

We look into the problem of stochastic resetting with refractory periods. The model dynamics comprises diffusive and motionless phases. The diffusive phase ends at random time instants, at which the system is reset to a given position—where the system remains at rest for a random time interval, termed the refractory period. A pathway formulation is introduced to derive exact analytical results for the relevant observables in a broad framework, with the resetting time and the refractory period following arbitrary distributions. For the paradigmatic case of Poissonian distributions of the resetting and refractory times, in general with different characteristic rates, closed-form expressions are obtained that successfully describe the relaxation to the steady state. Finally, we focus on the single-target search problem, in which the survival probability and the mean first passage time to the target can be exactly computed. Therein, we also discuss optimal strategies, which show a non-trivial dependence on the refractory period.

Origins

Abstract Scientific origins are information sources that transmit encoded information signals to receivers. Originary sciences identify information preserving receivers and decode the signals to infer their origins. Paradigmatic cases of scientific origination such as the Big Bang, the origins of species, horizontal gene transfer, the origin of the Polynesian potato, and ideational origins in the history of ideas are analyzed to discover what is common to them ontologically and epistemically. Some causes are not origins. Origination supervenes on causation, but has different properties. The unique properties of origins that causes do not share shield theories of origination from the kind of counterexamples and counterintuitive results that challenge comparable theories of causation. The epistemology of origination may serve as a basis for founding a novel epistemic and methodological division of the sciences into originary historical sciences and causal theoretical sciences.

Exploring the nonclassical dynamics of the “classical” Schrödinger equation

The introduction of nonlinearities into the Schrödinger equation has been considered in the literature as an effective manner to describe the action of external environments or mean fields. Here, we explore the nonlinear effects induced by subtracting a term proportional to Bohm’s quantum potential to the usual (linear) Schrödinger equation, which generates the so-called “classical” Schrödinger equation. Although a simple nonlinear transformation allows us to recover the well-known classical Hamilton–Jacobi equation, by combining a series of analytical results (in the limiting cases) and simulations (whenever the analytical treatment is unaffordable), we find an analytical explanation to why the dynamics in the nonlinear “classical” regime is still strongly nonclassical. This is even more evident by establishing a one-to-one comparison between the Bohmian trajectories associated with the corresponding wave function and the classical trajectories that one should obtain. Based on these observations, it is clear that the transition to a fully classical regime requires extra conditions in order to remove any trace of coherence, which is the truly distinctive trait of quantum mechanics. This behavior is investigated in three paradigmatic cases, namely, the dispersion of a free propagating localized particle, the harmonic oscillator, and a simplified version of Young’s two-slit experiment.

Exploring Obstacles Experienced by Learners with High-Functioning Autism in Pursuing Careers in Sports

This study investigated the obstacles faced by learners with high-functioning autism in pursuing careers in sports, at a special school in Johannesburg, South Africa. It explored strategies that these learners can use to overcome obstacles they may experience in pursuing careers in sports. The study used a qualitative methodology informed by an interpretive paradigm and intrinsic case study design. The study involved eighteen participants, namely six teachers, six parents and six learners. Data were collected through focus group interviews, semi-structured interviews, art-based career collages and document analysis. The data were analyzed through thematic analysis. The findings show that these learners face numerous obstacles in pursuing sports careers due to a lack of resources, inadequate facilities, lack of parental involvement, discrimination, inadequate training of teachers, lack of sporting activities, and lack of appropriate school structures. The learners face personal obstacles, including verbal, writing, social, interactional, and behavioral deficiencies. The findings indicate a need to provide these learners with adequate and relevant resources and facilities at home, school, and elsewhere to tackle these obstacles.
