Enactivism is a family of theories that construe action as constitutive of cognition and reject the need to postulate representations in order to explain all cognitive activities. Acknowledging a biologically basic, non-representational mode of cognition, however, raises the question of how to explain higher or more complex cognitive acts, what we call explanatory integration challenge. In this paper, we critically discuss some attempts to meet that challenge through scaling up basic cognition and through scaling down complex cognition (...) within the enactivist research program.

This chapter explores the idea that phylogenetic diversity plays a unique role in underpinning conservation endeavour. The conservation of biodiversity is suffering from a rapid, unguided proliferation of metrics. Confusion is caused by the wide variety of contexts in which we make use of the idea of biodiversity. Characterisations of biodiversity range from all-variety-at-all-levels down to variety with respect to single variables relevant to very specific conservation contexts. Accepting biodiversity as the sum of a large number of individual measures (...) results in an empirically intractable framework. However, large-scale decisions cannot be based on biodiversity variables inferred from local conservation imperatives because the variables relevant to the many systems being compared would be incommensurate with one another. We therefore need some general conception of biodiversity that would make tractable such large-scale environmental decision-marking. We categorise the large array of strategies for the measurement of biodiversity into four broad groups for consideration as general measures of biodiversity. We compare common moral justifications for the conservation of biodiversity and conclude that some form of instrumental value is the most plausible justification for biodiversity conservation. Although this is often interpreted as a reliance on option value, we opt for a broadly consequentialist characterisation of biodiversity conservation. We conclude that the best justified general measure of biodiversity will be some form of phylogenetic diversity. (shrink)

Topicality of the research topic. As a result of the COVID-19 pandemic, there is an increase in the instability of the structure of ecosocial systems. Technological innovations have led to a sharp deterioration in natural social ecodynamics. The aim of the research is the conceptual modeling of the proliferation of biopolitics from the social sphere to the field of international relations with the subsequent transformation into a systemic factor of the global evolutionary process. Research methods and results. The model is (...) based on our previously proposed concept of a three-module stable evolutionary strategy of technogenic civilization. In relation to the triple spiral of anthropo-socio-technogenesis, i.e., the historical development of the cultural-ecological niche of Homo sapiens, constructed by him, this means the following. Periods of stable progressive growth of evolutionary and civilizational success are replaced by periods of various scales crisis, up to civilizational or even biological-evolutionary singularity. During the crisis, the importance of the political factor increases sharply, and over the past 50 years, this primarily relates to the field of biopolitics. The regional differentiation of the biopolitical sphere reconstruction during the fight against the pandemic will inevitably complicate international relations not only between regions that belong to different cultural and civilizational types. Probably less so, the same problems will affect the reconciliation of differences caused by geopolitical, interethnic, religious and even economic (competition) reasons. The first phase of the adaptive civilizational response is to reduce the degree of connection between the individual socio-cultural elements of modern civilization, i.e., slowing down the globalization process and intensifying interregional conflicts of various contents. In particular, such contradictions will be most acute in the post-Soviet geopolitical space, where the conditions of the civilizational rift are imposed on the conflicts of the transition period. Due to the specifics of modern high technologies, the process will enter the phase of global socio-techno-ecological self-developing systems reconstruction, which includes man as its element. And the obvious conclusion will be the transition of the development of biopolitical issues to a new, no longer international, but global-evolutionary level. In our understanding, transbiopolitics is a political issue related to the rationalization of the global evolutionary process. The latter will become a bearing element of the global process of evolution of the noosphere with the subsequent complication and increase of cohesion between separate sociocultural types which are a part of system of the modern globalizing civilization.

The development of nuclear energy technologies in the second half of the 20th century came with great hopes of rebuilding nations recovering from the devasta-tion of the Second World War or recently released from colonial rule. In coun-tries like France, India, the USA, Canada, Russia, and the United Kingdom, nuclear energy became the symbol of development towards a modern and technologically advanced future. However, after more than six decades of experi-ence with nuclear energy production, and in the aftermath of the (...) Fukushima nuclear disaster, it is safe to say that nuclear energy production is not without its problems.Some of these problems have their origins in the very materiality of the technolo-gies involved. For example, not only does the use of highly radioactive materials give rise to risks for the current generation (e.g., in the potential for disaster when reactors melt down) but high-level radioactive waste from nuclear energy production presents a serious intergenerational problem for which an acceptable final solution or its implementation remains elusive. Moreover, nuclear energy technologies have specific social and political consequences. For example, they have been said to be authoritarian technologies (Winner, 1980), requiring cen-tralized authority, secrecy, and technocratic decision-making. While some of these problems could have been foreseen before nuclear energy technologies were introduced, others only arose after these technologies were already integrated into the social and infrastructural fabric of our lives. Addition-ally, new technologies (e.g., Generation III, III+ and IV reactors) are still being developed, bringing with them new and uncertain hazards and risks. Ignorance and uncertainty about the possible deleterious effects of introducing a new technology are inevitable, especially if the technology is complex, large time-scales are involved, or risks depend on social or political factors unforeseen in the design stage. However, this should not deter us from developing and intro-ducing new technologies. Rather, it should motivate us to organize these ‘exper-iments’ with new technologies in society in such a way that we can learn about their possible hazards and risks as effectively and responsibly as possible (van de Poel, 2011, 2015). In this way, it is possible to minimize risks and avoid unwant-ed moral, social or political developments. However, organizing such experi-ments responsibly also means that one could come to the conclusion that continuing an experiment is no longer responsible or desirable. Should we be prepared for such a scenario, and if so, how could we do that? One possible strategy to tackle this issue is that the technology and its introduction should be reversible. The aim of this thesis is to further explore this strategy by answering the following main research question (RQ) and accompanying subquestions (SQ):RQ: What are the implications of reversibility for the responsible develop-ment and implementation of nuclear energy technologies?SQ1: Under what conditions can nuclear energy technologies be considered reversible?SQ2: Why should nuclear energy technologies be reversible?SQ3: If so, how could the reversibility of nuclear energy technologies be achieved?After the introductory chapter 1, the chapters that form the main body of this dissertation each provide a distinct contribution to answering the three subques-tions and, by extension, the main research question. Guided by three historical case studies of nuclear energy technology development (i.e., India, France and the USA), chapter 2 answers the first subquestion by formulating the two condi-tions under which it can be considered reversible, i.e., 1) the ability to stop the further development and deployment of a that technology in society, and 2) the ability to undo the undesirable outcomes (material, institutional or symbolic) of the development and deployment of the technology. Chapter 3 subsequently tackles the second subquestion by establishing the general desirability of technological reversibility by virtue of its relation to responsibility in Emmanuel Levinas’ ethical phenomenology. It argues that technology development is a legitimate response to responsibility but inevitably falls short of the responsibility that inspires it, incessantly calling for technological and political change in the process. Having thus argued that nuclear energy technologies should ideally be reversible, chap-ters 4 and 5 work towards specific strategies to achieve technological reversibil-ity. Chapter 4 first investigates the processes that make it difficult to stop the further development and implementation of a nuclear energy technology in society, thus provid-ing input on how to fulfill the first condition for the reversibility of nuclear energy technologies. To do so, it presents a phenomenological perspective on technology and its adoption based on the work of Alfred Schutz. It also explores different ways in which technology adoption drives the processes of path depend-ence towards technological lock-in. Chapter 5 examines the history of geological disposal of high-level radioactive waste in the USA. It identifies a number of concrete policy pitfalls that could lead to lock-in and that should consequently be avoided. It also presents a number of general design strategies that could facilitate the undoing of undesirable consequences of a technology, thus providing input on how to fulfill the second condition for the reversibility of nuclear energy technol-ogies.Chapter 6 summarizes the central findings of the thesis and explains how these help to answer the research questions. On top of this, it reflects on a number of complications connected to reversibility considerations. Based on this, it is concluded that the question of irreversibility and reversibility is context- and technology-specific and a matter of degree. The chapter concludes with a reflec-tion on generalizations and limitations of the results. Finally, chapter 7 discusses the implications of this dissertation’s results for responsibly experimenting with nuclear energy technologies in society. (shrink)

After motivating a framework for evaluating top-down, middle-out, middle-in, and bottom-up ontology development strategies, we apply our framework to investigate whether infectious disease ontologies - specifically, the Virus Infectious Disease Ontology (VIDO) and the Coronavirus Infectious Disease Ontology (CIDO) - effectively promote semantic interoperability.

The article examines the impact of the virtual public sphere on how urban spaces are experienced and conceived in our data-driven society. It places particular emphasis on urban scale digital twins, which are virtual replicas of cities that are used to simulate environments and develop scenarios in response to policy problems. The article also investigates the shift from the technical to the socio-technical perspective within the field of smart cities. Despite the aspirations of urban scale digital twins to enhance the (...) participation of citizens in the decision-making processes relayed to urban planning strategies, the fact that they are based on a limited set of variables and processes makes them problematic. The article aims to shed light on the tension between the real and the ideal at stake during this process of abstracting sets of variables and processes in the case of urban scale digital twins.

The metaphor of weighing reasons brings to mind a single (double-pan balance) scale. The reasons for φ go in one pan and the reasons for ~φ go in the other. The relative weights, as indicated by the relative heights of the two pans of the scale, determine the deontic status of φ. This model is simple and intuitive, but it cannot capture what it is to weigh reasons correctly. A reason pushes the φ pan down toward permissibility (has justifying (...) weight) only insofar as it pushes the ~φ pan up toward impermissibility (has requiring weight). Thus, Single Scale is committed to Single Proportion (first pass): all reasons have the same proportion of justifying and requiring weight. Many normative theories reject Single Proportion, and they are not thereby confused about how to weigh reasons. One can be mistaken about the weight of a reason without being confused about how reasons are to be weighed. Single Scale is problematic, not because it appeals to the image of a scale, but because it appeals to the image of a single scale. We need two scales to capture what it is to weigh reasons correctly. (shrink)

Following the previous relevant works [1]-[3], a scaling analysis is performed to derive a set of scaling criteria which were thought to be suitable for reproducing the major thermal-hydraulic phenomena in a scaled-down CANDU moderator tank similar to that in a prototype power plant during a full power steady state condition. The objective of building a scaled-down moderator tank is to generate the experimental data necessary to validate the computer codes which are used to analyze the (...) accident analysis of CANDU-6 plants. The major variables of interests in this paper are moderator flow velocity and temperature of the moderator which is D2O inside the moderator tank during a steady state and transient conditions. The reason is that the local subcooling of the moderator is found to be a critical parameter determining whether the stable film boiling can sustain on the outer surface of the calandria tube if the contact of overheated pressure tube and cold calandria tube should occur due to pressure tube ballooning during LBLOCA with ECC injection failure [4]. The key phenomena involved include the inlet jet development and impingement, buoyancy force driven by the moderator temperature gradient caused by non-uniform direct heating of the moderator, and the pressure drop due to viscous friction of the flow across the calandria tube array. In this paper, the previous researches are reviewed, some concerns or potential problems associated with them implied by comparing CFD analyses results between the CANDU-6 moderator tank and 1/4 scaled-down test facility are described, and as a way to examine the assumption of the scaling analysis is true an order-of-magnitude analyses are performed. Based on the results of these analyses the assumption of neglecting and terms cannot be justified for the power of 0.5 MW and 1.566 MW for the 1/4 scaled-down facility. Further investigation is thought to be necessary to confirm this result, i.e. if the scaling of the previous work1 is justifiable by some other independent analyses. (shrink)

While the predominant focus of the philosophical literature on scientific modeling has been on single-scale models, most systems in nature exhibit complex multiscale behavior, requiring new modeling methods. This challenge of modeling phenomena across a vast range of spatial and temporal scales has been called the tyranny of scales problem. Drawing on research in the geosciences, I synthesize and analyze a number of strategies for taming this tyranny in the context of conceptual, physical, and mathematical modeling. This includes several strategies (...) that can be deployed in physical modeling, even when strict dynamical scaling fails. In all cases, I argue that having an adequate conceptual model—given both the nature of the system and the particular purpose of the model—is essential. I draw a distinction between depiction and representation, and use this research in the geosciences to advance a number of debates in the philosophy of modeling. (shrink)

The increasing complexity and scale of modern computing needs have led to the development and adoption of cloud computing as a ubiquitous paradigm for data storage and processing. The hybrid cloud model, which combines both public and private cloud infrastructures, has been particularly appealing to organizations that require both the scalability offered by public clouds and the security features of private clouds. Various strategies for configuring and managing resources have been developed to optimize the hybrid cloud environment. These strategies aim (...) to balance conflicting objectives such as cost-efficiency, performance optimization, security, and compliance with regulatory standards. This exploratory research focused on evaluating the efficiency and limitations of different configuration strategies in hybrid cloud environments. Findings indicate that each approach presents distinct advantages. Improving resource utilization and automating governance processes are significant advantages of Policy-based Resource Management, which leads to costeffectiveness. Intelligent routing of traffic is a feature of Cross-cloud Load Balancing, resulting in optimized performance and higher service availability. By centralizing control, the Hybrid Cloud Service Mesh allows for secure and streamlined cross-service communication. A notable feature of Cross-cloud Container Orchestration is its ability to simplify the migration of applications across diverse cloud environments. For immediate threat detection and regulatory compliance, real-time monitoring is facilitated by Log Management and Analytics. However, Policy-based Resource Management can be complex and inflexible. Extra costs for data transfer between different cloud providers are a drawback of Crosscloud Load Balancing. Additional network hops create latency issues in Hybrid Cloud Service Mesh configurations. If configured incorrectly, Cross-cloud Container Orchestration could expose the system to security risks. Finally, Log Management and Analytics require both ample storage and advanced analytical capabilities. (shrink)

Background: The feeding modalities used in school meal programs—such as breakfast, lunch, dinner, snacks, and take-home rations—are influenced by various factors, including supply chain constraints and technical challenges in food distribution. The methods of supply sourcing, whether through domestic or foreign food reserves via in-kind donations or purchases, play a critical role in shaping the feeding options provided. Aim: This study aims to examine the association between supply-sourcing strategies, i.e., domestic and foreign in-kind donations and national-international purchases, with the feeding (...) modalities applied in school meal programs. Methods: The Bayesian Mindsponge Framework, combining the reasoning strengths of Mindsponge Theory and inference advantages of Bayesian analysis, was employed on a dataset of government representatives who manage large-scale school meal programs across 126 countries. Results: The findings revealed that sourcing supplies through in-kind donations from neighboring or distant countries showed a highly reliable negative association with the feeding modalities of school meal programs, while those from the national bodies showed an ambiguous relationship. The purchasing methods—whether domestic or foreign—tended to exhibit positive associations with feeding modalities, though these associations were only weakly reliable. Conclusions: The findings reveal substantial rooms to improve the effectiveness of supply purchasing strategies in enhancing school meal program feeding modalities. Further research is needed to examine the impact of sourcing supplies through domestic in-kind donations on feeding outcomes. Additionally, developing strategic plans to optimize the use of in-kind donations from international organizations is strongly recommended to avoid its negative consequences and further enhance program effectiveness.

Some natural languages do not lexically distinguish between modals of possibility and modals of necessity. From the perspective of languages like English, modals in such languages appear to do double duty: they are used both where possibility modals are expected and where necessity modals are expected. The Nez Perce modal suffix o’qa offers an example of this behavior. I offer a simple account of the flexibility of the o’qa modal centered on the absence of scalar implicatures. O’qa is a possibility (...) modal that does not belong to a Horn scale; its use is never associated with a scalar implicature. Accordingly, in an upward entailing environment, φ-o’qa is appropriate whenever there are accessible φ-worlds, even if indeed all accessible worlds are φ-worlds. In a downward entailing environment, the flexibility of the o’qa modal is seen no more. Here, neither o’qa nor English possibility modals are associated with scalar implicatures, and the use of o’qa exactly parallels the use of English modals of possibility. -/- Given that o’qa is a possibility modal that does not contrast with a modal of necessity, just how do you talk about necessities in Nez Perce? Speakers translating into Nez Perce rely on a variety of techniques to paraphrase expressions of simple necessity away. Their strategies highlight an area where Nez Perce and English plausibly differ in the range of propositions they convey. The data cast doubt on any strong form of effability as a language universal.

Perception of time is susceptible to distortions; among other factors, it has been suggested that the perceived duration of a stimulus is affected by the observer’s expectations. It has been hypothesized that the duration of an oddball stimulus is overestimated because it is unexpected, whereas repeated stimuli have a shorter perceived duration because they are expected. However, recent findings suggest instead that fulfilled expectations about a stimulus elicit an increase in perceived duration, and that the oddball effect occurs because the (...) oddball is a target stimulus, not because it is unexpected. Therefore, it has been suggested that top-down attention is sometimes sufficient to explain this effect, and sometimes only necessary, with an additional contribution from saliency. However, how the expectedness of a target stimulus and its salient features affect its perceived duration is still an open question. In the present study, participants’ expectations about and the saliency of target stimuli were orthogonally manipulated with stimuli presented on a short (Experiment 1) or long (Experiment 2) temporal scale. Four repetitive standard stimuli preceded each target stimulus in a task in which participants judged whether the target was longer or shorter in duration than the standards. Engagement of top-down attention to target stimuli increased their perceived duration to the same extent irrespective of their expectedness. A small but significant additional contribution to this effect from the saliency of target stimuli was dependent on the temporal scale of stimulus presentation. In Experiment 1, saliency only significantly increased perceived duration in the case of expected target stimuli. In contrast, in Experiment 2, saliency exerted a significant effect on the overestimation elicited by unexpected target stimuli, but the contribution of this variable was eliminated in the case of expected target stimuli. These findings point to top-down attention as the primary cognitive mechanism underlying the perceptual extraction and processing of task-relevant information, which may be strongly correlated with perceived duration. Furthermore, the scalar properties of timing were observed, favoring the pacemaker-accumulator model of timing as the underlying timing mechanism. (shrink)

As detailed in The Evolutionary Manifesto and Evolution’s Arrow, an understanding of the large-scale processes that govern the evolution of life is capable of making sense of human existence.

A classic analytic approach to biological phenomena seeks to refine definitions until classes are sufficiently homogenous to support prediction and explanation, but this approach founders on cases where a single process produces objects with similar forms but heterogeneous behaviors. I introduce object spaces as a tool to tackle this challenging diversity of biological objects in terms of causal processes with well-defined formal properties. Object spaces have three primary components: (1) a combinatorial biological process such as protein synthesis that generates objects (...) with parts that are modular, independent, and organized according to an invariant syntax; (2) a notion of “distance” that relates the objects according to rules of change over time as found in nature or useful for algorithms; (3) mapping functions defined on the space that map its objects to other spaces or apply an evaluative criterion to measure an important quality, such as parsimony or biochemical function. Once defined, an object space can be used to represent and simulate the dynamics of phenomena on multiple scales; it can also be used as a tool for predicting higher-order properties of the objects, including stitching together series of causal processes. Object spaces are the basis for a strategy of theorizing, discovery, and analysis in biology: as heuristic idealizations of biology, they help us transform inchoate, intractable problems into articulated, well-structured ones. Developing an object space is a research strategy with a long, successful history under many other names, and it offers a unifying but not overreaching approach to biological theory. (shrink)

In this paper, I will present the empirical version of the slippery slope argument (SSA) in the field of genome editing. According to the SSA, if we adopt germline manipulation of embryos we will eventually end up performing or allowing something morally reprehensible, such as new coercive eugenics. I will investigate the actual possibility of sliding towards eugenics: thus, I will examine enhancement and eugenics both in the classical and liberal versions, through the lens of SSA. In the first part, (...) I will discuss the classical eugenics from a historical perspective and conclude that classical eugenics is morally deplorable; but by currently accepting genome editing I argue that it is not possible to ‘slip’ into classical eugenics. Then, I will analyze liberal eugenics: I will consider Habermas’ and Sandel’s objections to liberal eugenics and genetic human enhancement. Subsequently, I will reply to these arguments affirming that, although it is not possible to refuse any form of genetic enhancement, liberal eugenics would not consider the principles of justice, non-maleficence, and non-instrumentalization; hence, it should be considered not morally acceptable. In addition, I will support the thesis according to which the possibility of relapsing into liberal eugenics is more likely than relapsing into classical eugenics. Then, I will present a strategy that, while avoiding falling into the undesirable scenarios related to SSA, still accepts some application of germline genome editing of embryos and gametes. In such a way, I will show that even if we accept the plausibility of a certain slip into an undesirable scenario, SSA does not offer conclusive reasons to forbid any use of germline genome editing technique in both therapeutic and enhancement fields.

The striving for a more equal society has been an inspiring ideal for social policy and a powerful engine for the foundations of the welfare state. However, equality as a political concept has been subject to ongoing criticism and has been gradually denounced.

This strategy has been extensively (...) debated in political philosophy but has not been examined through a social policy perspective. This gap is addressed in the following discussion which aims to generate achievable policy implications with greater commitment to the ideal of equality. (shrink)

E-business capabilities encompass the use of technology and digital infrastructure, while digital marketing strategies are employed to attract and retain online customers. The study examines the effect of e-business capabilities through digital marketing strategies on the customer satisfaction and loyalty of UAE e-commerce industry. The research is descriptive and explanatory, (...) and uses a structured 5-scale Likert questionnaire to collect data from the HR managers of 135 e-commerce companies based in UAE. The statistical analysis is performed using structural equation modeling. The findings highlight the significant relationship of the study variables. Consequently, the results of this study provide valuable insights for e-commerce businesses, elucidating the need to invest in robust e-business capabilities to support effective digital marketing efforts. Additionally, the research underscores the significance of tailoring digital marketing strategies to align with specific business objectives and customer segments. The study also contributes to the literature on digital transformation, by demonstrating how e-business capabilities and digital marketing strategies can enable e-commerce firms to adapt and thrive in the dynamic and competitive digital environment.

An objection to shifty epistemologies such as subject-sensitive invariantism is that it predicts that agents are susceptible to guaranteed losses. Bob Beddor (Analysis, 81, 193–198, 2021) argues that these guaranteed losses are not a symptom of irrationality, on the grounds that forgetful agents are susceptible to guaranteed losses without being irrational. I agree that forgetful agents are susceptible to guaranteed losses without being irrational– but when we investigate why, the analogy with shifty epistemology breaks down. I argue that agents (...) with shifty epistemologies are susceptible to guaranteed losses in a way which is a symptom of irrationality. Along the way I make a suggestion about what it takes for an agent to be coherent over time. I close by offering a taxonomy of shifty epistemologies. (shrink)

Today, resilience is used in many societal contexts for understanding how things respond to risks and for improving their performance in this regard, having also become a prominent approach for adapting to climate change. Yet, despite the broad appeal of resilience and resilience-based approaches within and outside academia, there are persisting puzzles about how to interpret resilience, its relation to competing concepts and approaches, or its desirability. Some proponents of resilience advise caution with the normative use of the term, noting (...) that resilience is a purely descriptive and ambivalent quality, which can be good in some circumstances but not in others. Critics have also noted that resilience approaches can be technocratic and that they tend to conceal the needs and vulnerabilities of the poor. -/- These examples demonstrate the need for reflecting on the status and significance of a term that is so widely used in academia and across the science-policy divide, but whose meaning and value are so fiercely disputed. Given that resilience is already informing many large-scale and significant societal efforts, they also raise the need to ask under which conditions such efforts could be just. -/- This work uses philosophical perspectives from ethics, metaethics and justice theory for revisiting recent debates on the meaning and normative status of this concept, with special emphasis on understanding the normative guidance that diverse interpretations of resilience can offer and disclosing the implications that this may have for achieving justice in and through resilience-based interventions.

This article argues for a task-based approach to identifying and individuating cognitive systems. The agent-based extended cognition approach faces a problem of cognitive bloat and has difficulty accommodating both sub-individual cognitive systems ("scaling down") and some supra-individual cognitive systems ("scaling up"). The standard distributed cognition approach can accommodate a wider variety of supra-individual systems but likewise has difficulties with sub-individual systems and faces the problem of cognitive bloat. We develop a task-based variant of distributed cognition designed to (...) scale up and down smoothly while providing a principled means of avoiding cognitive bloat. The advantages of the task-based approach are illustrated by means of two parallel case studies: re-representation in the human visual system and in a biomedical engineering laboratory. (shrink)

Korea Atomic Energy Research Institute (KAERI) has been carrying out a scaled-down moderator test program to simulate the CANDU-6 moderator circulation phenomena during steady state operation and accident conditions. The Moderator Circulation Test (MCT) facility was designed and constructed as 1/4 scale of the prototype of CANDU-6 reactor. In the present work spatial distribution of two-dimensional velocity in the MCT facility under isothermal condition was measured using planar Particle Image Velocimetry (PIV) system which consists of double pulsed laser, synchronizer, (...) and high speed camera. TSI’s Insight TM 4G software was used to perform PIV image capturing, PIV calculation and post processing. 10 μm sized silver-coated hollow sphere particles were used as flow tracer particles. Multiple experiments were conducted to cover large area of the MCT facility with limited field of view of a single camera. Instantaneous and averaged velocity field were analyzed for each spatial position and flow rate. This research is capable of offering validation data for self-reliant CFD tools to predict moderator subcooling margin in CANDU-6 reactor. (shrink)

Teaching a compulsory, large-scale Philosophy of Economics (PoE) course to economics students presents distinct challenges. Instructors face a heterogeneous student body with varying levels of interest in the topics, diverse occupational goals and a limited philosophical background. Unlike elective courses, for which students self-select based on interest, a compulsory course entails motivating disengaged students and managing their expectations. We put forward the case for a student-oriented approach to teaching PoE, emphasising four key strategies: recognising students’ limited philosophical knowledge, demonstrating the (...) relevance of PoE to their professional and personal lives, using real-world problems to engage them and avoiding the oversimplification of topics. We argue that PoE instruction should account for the distinct characteristics of economics students, moving beyond a supply-driven approach. Our suggestions aim to enhance student engagement and provide practical guidance for instructors navigating the challenges of teaching PoE at scale. (shrink)

Background: Food fortification refers to the process of adding nutrients to foods during their production. It is a cost-effective strategy with well-documented health, economic, and social benefits. Food fortification practices in school meal programs need guidance and legal support from various national policies. Aim: This study aims to analyze how various national policies—such as those related to school feeding, nutrition, health, food safety, agriculture, and the private sector—associate with the implementation of in-school food fortification among countries with school meals (...) programs. Methods: The Bayesian Mindsponge Framework, combining the reasoning strengths of Mindsponge Theory and inference advantages of Bayesian analysis, was employed on a dataset of 126 government representatives who manage large-scale school meal programs in 126 different countries. Results: Findings showed that food safety policy and agriculture policy were positively and significantly associated with the in-school food fortification practices, while school feeding policy and private sector policy had ambiguous relationships with these practices. Nutrition policy and health policy had a significant negative association with food fortification practices among countries implementing school meal programs. Conclusions: Findings underscore the strong position of food safety policy and agriculture policy in guiding food fortification practices in school meal programs. There is a need to re-assess the implemented nutrition policy and health policy due to their significant negative associations with these practices. Enhancing and strengthening the school feeding policy and private sector policy may increase their potencies in giving positive impacts on in-school food fortification practices. (shrink)

Background: Food insecurity condition challenges the availability of food, access to food, food supply stability, and food utilization. Food banks play a major role in the food aid sector by distributing donated and purchased groceries directly to food-insecure families, thus significantly impacting food insecurity. On the other hand, school meal programs are implemented in many countries to combat food insecurity among school-aged children. The synergy between school meal programs and food banks has a great potency to combat food insecurity among (...) children effectively. Aim: This study aims to examine the association between experts’ involvement—such as nutritionists, farmers, and private sectors—and community engagement, including parents and others, with the linkage between food banks and school meal programs among implementing countries. Methods: The Bayesian Mindsponge Framework, combining the reasoning strengths of Mindsponge Theory and inference advantages of Bayesian analysis, was employed on a dataset of 126 government representatives who manage large-scale school meal programs in 126 different countries. Results: Findings showed that the involvement of nutritionists and the private sector was positively associated with the linkage between food banks and school meal programs, while farmers’ involvement showed an ambiguous association. The engagement of parents and others also showed an ambiguous relationship with this linkage. Conclusions: Findings underscore the strong need to formulate strategies for increasing the involvement of nutritionists and the private sector to successfully link the food banks with school meal programs in implementing countries, which is crucial for effectively combating food insecurity among school-aged children.

Background: School meal programs are not only government initiatives but also community-driven efforts. Aiming to combat food insecurity among school-aged children effectively, these programs are executed in conjunction with food bank initiatives. Various community groups play a crucial role in the success of both food security initiatives. There is a need to improve community engagement to successfully link school meal programs with food banks to build program synergy, combating food insecurity through a two-sided approach. Aim: This study aims to examine (...) community engagement in school meals program by analyzing its purposeful focus on creating jobs and income-generating opportunities for different community groups, i.e., youths, women, and others. Methods: The Bayesian Mindsponge Framework, combining the reasoning strengths of Mindsponge theory and inference advantages of Bayesian analysis, was employed on a dataset of 126 government representatives who manage large-scale school meal programs in 126 different countries. Results: Findings showed that the school meals program’s purposeful focus on creating jobs and income-generating opportunities for women in the community was positively associated with community engagement, thereby supporting the linkage between the programs and food banks. In contrast, providing jobs and income-generating opportunities for youths and other community groups had an ambiguous association with community engagement in school meal programs. Conclusions: Findings underscore the importance of creating jobs and income-generating opportunities for women to improve community engagement in school meal programs. Formulating strategies that empower woman’s entrepreneurship may foster their involvement and engagement in school meal programs, promising to successfully link these programs with food bank initiatives among implementing countries.

The basis of perception is the processing and categorization of perceptual stimuli from the environment. Much progress has been made in the science of perceptual categorization. Yet there is still no consensus on how the brain generates sensory individuals, from sensory input and perceptual categories in memory. This chapter argues that perceptual categorization is highly variable across perceivers due to their use of different perceptual strategies for solving perceptual problems they encounter, and that the perceptual system structurally adjusts to the (...) strategies that are most successful. Despite this variability, the different sensory individuals that result when different perceivers rely on different strategies nonetheless correspond to actual external world objects/features. This view is called 'perceptual pluralism'. (shrink)

A new strategy for moving forward in the characterization of the Global Neuronal Workspace (GNW) is proposed. According to Dehaene, Changeux and colleagues, broadcasting is the main function of the GNW. However, the dynamic network properties described by recent graph-theoretic GNW models are consistent with many large-scale communication processes that are different from broadcasting. We propose to apply a different graph-theoretic approach, originally developed for optimizing information dissemination in communication networks, which can be used to identify the pattern of (...) frequency and phase-specific directed functional connections that the GNW would exhibit only if it were a broadcasting network.

I argue that part of Plato's strategy to neutralize the paradox of falsehood is to pin down various referents of the name 'being', τὸ ὄν. I focus on four and track their role in the dialogue's argument. They are: (1) any primary being; (2) the Kind Being; (3) any participant in the Kind Being; (4) a set of participants in the Kind Being.

Some prominent evidentialists argue that practical considerations cannot be normative reasons for belief because they can’t be motivating reasons for belief. Existing pragmatist responses turn out to depend on the assumption that it’s possible to believe in the absence of evidence. The evidentialist may deny this, at which point the debate ends in an impasse. I propose a new strategy for the pragmatist. This involves conceding that belief in the absence of evidence is impossible. We then argue that evidence (...) can play a role in bringing about belief without being a motivating reason for belief, thereby leaving room for practical considerations to serve as motivating reasons. I present two ways in which this can happen. First, agents can use evidence as a mere means by which to believe, with practical considerations serving as motivating reasons for belief, just as we use tools (e.g. a brake pedal) as mere means by which to do something (e.g. slow down) which we are motivated to do for practical reasons. Second, evidence can make it possible for one to choose whether or not to believe – a choice one can then make for practical reasons. These arguments push the debate between the evidentialist and the pragmatist into new territory. It is no longer enough for an evidentialist to insist that belief is impossible without evidence. Even if this is right, the outcome of the debate remains unsettled. It will hang on the ability of the evidentialist to respond to the new pragmatist strategy presented here. (shrink)

Outbreaks of novel influenza viruses are continually occurring on many places on our planet, with the ultimate and most extreme consequence being a full-scale pandemic. Modern communication technology is widely used for risk communication regarding recommended change in behavior patterns and other precautions in order to mitigate the transmission. However, the assumption and bias that modern communication technology constitutes the norm causes vulnerable groups to be at possible risk of systematic exclusion to correct and updated information. Through conducting a literature- (...) and case analysis, the aim of this study is to identify insufficient or inadequate risk communication efforts in South Korea and Vietnam during influenza outbreaks, especially with concern of vulnerable groups. Further, to analyze how national influenza preparedness plans observe or ignore these insufficiencies. Results show that vulnerable groups are explicitly recognized in the preparedness plan of Vietnam. However, the South Korean preparedness plan show a more homogenous approach. Both South Korea and Vietnam showed a broad variety of channels used in their risk communication strategies which could be positive in terms of a broad outreach to a heterogenous population, including vulnerable groups. Four key factors that moderate the outcomes of risk communication were identified: Channels, Messages, Transparency and Trust. (shrink)

Conspiracy theories should be neither believed nor investigated - that is the conventional wisdom. I argue that it is sometimes permissible both to investigate and to believe. Hence this is a dispute in the ethics of belief. I defend epistemic ‘oughts’ that apply in the first instance to belief-forming strategies that are partly under our control. I argue that the policy of systematically doubting or disbelieving conspiracy theories would be both a political disaster and the epistemic equivalent of self-mutilation, since (...) it leads to the conclusion that history is bunk and the nightly news unbelievable. In fact (of course) the policy is not employed systematically but is only wheeled on to do down theories that the speaker happens to dislike. I develop a deductive argument from hard-to-deny premises that if you are not a ‘conspiracy theorist’ in my anodyne sense of the word then you are an ‘idiot’ in the Greek sense of the word, that is, someone so politically purblind as to have no opinions about either history or public affairs. The conventional wisdom can only be saved (if at all) if ‘conspiracy theory’ is given a slanted definition. I discuss some slanted definitions apparently presupposed by proponents of the conventional wisdom (including, amongst others, Tony Blair) and conclude that even with these definitions the conventional wisdom comes out as deeply unwise. I finish up with a little harmless fun at the expense of David Aaronvitch whose abilities as a rhetorician and a popular historian are not perhaps matched by a corresponding capacity for logical thought.

The universality of critical phenomena is best explained by appeal to the Renormalisation Group (RG). Batterman and Morrison, among others, have claimed that this explanation is irreducible. I argue that the RG account is reducible, but that the higher-level explanation ought not to be eliminated. I demonstrate that the key assumption on which the explanation relies – the scale invariance of critical systems – can be explained in lower-level terms; however, we should not replace the RG explanation with a bottom-up (...) account, rather we should acknowledge that the explanation appeals to dependencies which may be traced down to lower levels.

Many scholars agree that the Internet plays a pivotal role in self-radicalization, which can lead to behaviours ranging from lone-wolf terrorism to participation in white nationalist rallies to mundane bigotry and voting for extremist candidates. However, the mechanisms by which the Internet facilitates self-radicalization are disputed; some fault the individuals who end up self-radicalized, while others lay the blame on the technology itself. In this paper, we explore the role played by technological design decisions in online self-radicalization in its myriad (...) guises, encompassing extreme as well as more mundane forms. We begin by characterizing the phenomenon of technological seduction. Next, we distinguish between top-down seduction and bottom-up seduction. We then situate both forms of technological seduction within the theoretical model of dynamical systems theory. We conclude by articulating strategies for combatting online self-radicalization.

Two decades ago, in 1994, in the context of the 4th EU Framework Programme, ELSA was introduced as a label for developing and funding research into the ethical, legal and social aspects of emerging sciences and technologies. Currently, particularly in the context of EU funding initiatives such as Horizon2020, a new label has been forged, namely Responsible Research and Innovation. What is implied in this metonymy, this semantic shift? What is so new about RRI in comparison to ELSA? First of (...) all, for both labels, the signifier was introduced in a top-down manner, well before the concept that was signified by it had acquired a clear and stable profile. In other words, the signifier preceded the research strategies actually covered by these labels. Moreover, the newness of RRI does not reside in its interactive and anticipatory orientation, as is suggested by authors who introduced the term, but rather in its emphases on social-economic impacts.

WINNER BEST SOCIAL PHILOSOPHY BOOK IN 2021 / NASSP BOOK AWARD 2022 -/- Together we can often achieve things that are impossible to do on our own. We can prevent something bad from happening or we can produce something good, even if none of us could do it by herself. But when are we morally required to do something of moral importance together with others? This book develops an original theory of collective moral obligations. These are obligations that individual moral (...) agents hold jointly, but not as unified collective agents. To think of some of our obligations as joint or collective is the best way of making sense of our intuitions regarding collective moral action problems. Where we have reason to believe that our efforts are most efficient as part of a collective endeavor we may incur collective obligations together with others who are similarly placed as long as we are able to establish compossible individual contributory strategies towards that goal. The book concludes with a discussion of “massively shared obligations” to large-scale moral problems such as global poverty. (shrink)

Famous results by David Lewis show that plausible-sounding constraints on the probabilities of conditionals or evaluative claims lead to unacceptable results, by standard probabilistic reasoning. Existing presentations of these results rely on stronger assumptions than they really need. When we strip these arguments down to a minimal core, we can see both how certain replies miss the mark, and also how to devise parallel arguments for other domains, including epistemic “might,” probability claims, claims about comparative value, and so on. (...) A popular reply to Lewis's results is to claim that conditional claims, or claims about subjective value, lack truth conditions. For this strategy to have a chance of success, it needs to give up basic structural principles about how epistemic states can be updated—in a way that is strikingly parallel to the commitments of the project of dynamic semantics.

Wild animal reproduction poses an important moral problem for animal rights theorists. Many wild animals give birth to large numbers of uncared-for offspring, and thus child mortality rates are far higher in nature than they are among human beings. In light of this reproductive strategy – traditionally referred to as the ‘r-strategy’ – does concern for the interests of wild animals require us to intervene in nature? In this paper, I argue that animal rights theorists should embrace fallibility-constrained (...) interventionism: the view that intervention in nature is desirable but should be constrained by our ignorance of the inner workings of ecosystems. Though authors sometimes assume that large-scale intervention requires turning nature into an enormous zoo, I suggest an alternative. With sufficient research, a new form of gene editing called CRISPR promises to one day give us the capacity to intervene without perpetually interfering with wild animals’ liberties. (shrink)

Authors critical of corporate power focus almost exclusively on one solution: bringing it under democratic control. However important this is, there are at least two other options, which are rarely discussed: reducing powerful firms’ size and influence, or accepting corporate power as a necessary evil. This article provides a comparative perspective for evaluating all three options. It argues that the trade-offs we face in responding to corporate power have a trilemmatic structure. The pure strategies of accepting powerful firms, breaking them (...) up, or rendering them more accountable are each incompatible with one of three important values: power balance, economies of scale, and minimizing agency costs, respectively. While the latter two concepts are purely economic and efficiency-based, the value of power balance can be grounded in a variety of reasons. Different normative interpretations of power balance are discussed, along with their implications for policy choices within the trilemma. (shrink)

Even where an act appears to be responsible, and satisfies all the conditions for responsibility laid down by society, the response to it may be unjust where that appearance is false, and where those conditions are insufficient. This paper argues that those who want to place considerations of responsibility at the centre of distributive and criminal justice ought to take this concern seriously. The common strategy of relying on what Susan Hurley describes as a 'black box of responsibility' (...) has the advantage of not taking responsibility considerations to be irrelevant merely because some specific account of responsibility is mistaken. It can, furthermore, cope perfectly well with an absence of responsibility, even of the global sort implied by hard determinism and other strongly sceptical accounts. Problems for the black box view come in where responsibility is present, but in a form that is curtailed in one significant regard or another. The trick, then, is to open the box of responsibility just enough that its contents can be the basis for judgements of justice. I identify three 'moderately sceptical' forms of compatibilism that cannot ground judgements of justice, and are therefore expunged by the strongest 'grey box' view. (shrink)

Air pollution is a considerable environmental stressor for urban residents in developing countries. Perceived health risks of air pollution might induce migration intention among inhabitants. The current study employed the Bayesian Mindsponge Framework (BMF) to investigate the rationale behind the domestic and international migration intentions among 475 inhabitants in Hanoi, Vietnam – one of the most polluted capital cities worldwide. We found that people perceiving more impacts of air pollution in their daily life are more likely to have migration intention. (...) The effect of perceived air pollution impact on international migration intention is stronger than that of domestic migration. Acknowledging a family member’s air pollution-induced sickness moderated the association between perceived air pollution impact and domestic migration intention, while the personal experience of air pollution-induced sickness did not. In contrast, the moderation effect of personal experience of sickness became significant in the international migration circumstance, but the effect of information about a family member’s sickness was trivial. The findings suggest that urban inhabitants’ consideration of air pollution averting strategies reflects some characteristics of Homo Oeconomicus. Additionally, the individual’s socio-economic decision is seemingly insignificant on a social scale. Still, through environmental stressors as catalysts, such decisions might result in considerable social outcomes (e.g., internal migration and emigration). (shrink)

Although Gilles Deleuze never explicitly developed what might be considered a ‘philosophy of technology’, this article nonetheless attempts to outline the rudiments of a Deleuzian approach to technology by proposing a series of interrelated concepts: (1) prosthesis (technological artefacts are externalised organs); (2) proto-technicity, or originary technicity (but this technicity already exists in Nature, all the way down, and precedes any ‘theory’); (3) exodarwinism (the fact that evolutionary time has bifurcated, and technology evolves in a faster and accelerating time (...) scale); (4) de-specialisation or de-differentiation (what conditions the externalisation of organs is their deterritorialisation); (5) motricity (the link between the brain and the hand/mouth is primarily one of movement); (6) inscription, or graphism (the link between mouth and hand takes place through phonetic writing, when the hand reproduces speech in graphic inscriptions); (7) maker's knowledge (we know the organisations of matter found in nature through the organisations of matter that we ourselves have created); and finally, (8) totipotence (like a stem cell, the body is capable of externalising an almost unlimited number of forms and functions; it is itself an abstract and the source of abstractions).

This chapter focuses on the psychological mechanisms behind the construction of preference, especially the actual processes used by humans when they make decisions in their everyday lives or in business situations. The chapter uses cognitive psychological techniques to break down these processes and set them in their social context. When attributes are compatible with the response scale, they are assigned greater weight because they are most easily mapped onto the response. For instance, when subjects are asked to set a (...) price for a gamble this task is compatible with the information about the gamble payoff, which is also expressed in monetary values (e.g., dollars). Conversely, when the task requires a choice the payoff information is not easily mapped onto the response anymore and loses some of its salience. In fact, Slovic, Griffin, and Tversky (1990) could show that using non-monetary outcomes attenuates preference reversals when no compatibility between the pricing task and the outcome attribute was possible. An assumption of the compatibility effect is that response modes compatible with specific characteristics of the options (e.g., payoffs) draw attention to them. One of the main themes that has emerged from behavioral decision research during the past decades is the view that people's preferences are often constructed—not merely revealed—in the process of elicitation (see e.g. Slovic). This conception is derived in part from studies demonstrating that normatively equivalent methods of elicitation often give rise to systematically different responses. These "preference reversals" violate the principle of procedure invariance fundamental to theories of rational choice and raise difficult questions about the nature of human values. If different elicitation procedures produce different orderings of options, how can preferences be defined and in what sense do they exist? Describing and explaining such failures of invariance will require choice models of far greater complexity than the traditional models -/- . (shrink)

The Morality First strategy for developing AI systems that can represent and respond to human values aims to first develop systems that can represent and respond to moral values. I argue that Morality First and other X-First views are unmotivated. Moreover, according to some widely accepted philosophical views about value, these strategies are positively distorting. The natural alternative, according to which no domain of value comes “first” introduces a new set of challenges and highlights an important but otherwise obscured (...) problem for e-AI developers.

This paper is a complement to the recent wealth of literature suggesting a strong philosophical relationship between artificial life (A-Life) and artificial intelligence (AI). I seek to point out where this analogy seems to break down, or where it would lead us to draw incorrect conclusions about the philosophical situation of A-Life. First, I sketch a thought experiment (based on the work of Tom Ray) that suggests how a certain subset of A-Life experiments should be evaluated. In doing so, (...) I suggest that treating A-Life experiments as if they were just AI experiments applied to a new domain may lead us to see problems (like Searle’s “Chinese room”) which do not exist. In the second half of the paper, I examine the reasons for suggesting that there is a philosophical relationship between the two fields. I characterize the strong thesis for a translation of AI concepts, metaphors, and arguments into A-Life as the “global replacement strategy.” Such a strategy is only fruitful inasmuch as there is a strong analogy between AI and A-Life. I conclude the paper with a discussion of two areas where such a strong analogy seems to break down. These areas relate to eliminative materialism and the lack of a “subjective” element in biology. I conclude that the burden of proof lies with the person who wishes to import a concept from another discipline into A-Life, even if that other discipline is AI. (shrink)

This article aims to show that fundamentality is construed differently in the two most prominent strategies of analysis we find in physical science and engineering today: (1) atomistic, reductive analysis and (2) Systems analysis. Correspondingly, atomism is the conception according to which the simplest (smallest) indivisible entity of a certain kind is most fundamental; while systemism, as will be articulated here, is the conception according to which the bonds that structure wholes are most fundamental, and scale and/or constituting entities are (...) of no significance whatsoever for fundamentality. Accordingly, atomists maintain that the basic entities—the atoms—are fundamental, and together with the “external” interactions among them, are sufficient for illuminating all the features and behaviors of the wholes they constitute; whereas systemists proclaim that it is instead structural qualities of systems, that flow from internal relations among their constituents and translate directly into behaviors, that are fundamental, and by themselves largely (if not entirely) sufficient for illuminating the features and behaviors of the wholes thereby structured. Systemism, as will be argued, is consistent with the nonexistence of a fundamental “level” of nondecomposable entities, just as it is consistent with the existence of such a level. Still, systemism is a conception of the fundamental in quite different, but still ontological terms. Systemism can serve the special sciences—the social sciences especially—better than the conception of fundamentality in terms of atoms. Systemism is, in fact, a conception of fundamentality that has rather different uses—and importantly, different resonances. This conception of fundamentality makes contact with questions pertaining to natural kinds and their situation in the metaphysics of the special sciences—their situation within an order of autonomous sciences. The controversy over fundamentality is evident in the social sciences too, albeit somewhat imperfectly, in the terms of debate between methodological individualists and functionalists/holists. This article will thus clarify the difference between systemism and holism. (shrink)

This article is a comparative study between predictive processing (PP, or predictive coding) and cognitive dissonance (CD) theory. The theory of CD, one of the most influential and extensively studied theories in social psychology, is shown to be highly compatible with recent developments in PP. This is particularly evident in the notion that both theories deal with strategies to reduce perceived error signals. However, reasons exist to update the theory of CD to one of “predictive dissonance.” First, the hierarchical PP (...) framework can be helpful in understanding varying nested levels of CD. If dissonance arises from a cascade of downstream and lateral predictions and consequent prediction errors, dissonance can exist at a multitude of scales, all the way up from sensory perception to higher order cognitions. This helps understand the previously problematic dichotomy between “dissonant cognitive relations” and “dissonant psychological states,” which are part of the same perception-action process while still hierarchically distinct. Second, since PP is action-oriented, it can be read to support recent action-based models of CD. Third, PP can potentially help us understand the recently speculated evolutionary origins of CD. Here, the argument is that responses to CD can instill meta-learning which serves to prevent the overfitting of generative models to ephemeral local conditions. This can increase action-oriented ecological rationality and enhanced capabilities to interact with a rich landscape of affordances. The downside is that in today’s world where social institutions such as science a priori separate noise from signal, some reactions to predictive dissonance might propagate ecologically unsound (underfitted, confirmation-biased) mental models such as climate denialism.

Is it morally important to vote? It is common to think so, but both consequentialist and deontological strategies for defending that intuition are weak. In response, some theorists have turned to a role-based strategy, arguing that it is morally important to be an excellent citizen, and that excellent citizens vote. But there is a lingering puzzle: an individual vote changes very little (virtually nothing in large-scale elections), so why would the excellent citizen be so concerned to cast a ballot? (...) Why bother with something that has so little effect on the common good? This paper answers by developing the idea of respect for a practice, and then arguing that respect for democracy will often require citizens to vote. (shrink)

When radiocarbon dating techniques were applied to archaeological material in the 1950s they were hailed as a revolution. At last archaeologists could construct absolute chronologies anchored in temporal data backed by immutable laws of physics. This would make it possible to mobilize archaeological data across regions and time-periods on a global scale, rendering obsolete the local and relative chronologies on which archaeologists had long relied. As profound as the impact of 14C dating has been, it has had a long and (...) tortuous history now described as proceeding through three revolutions, each of which addresses distinct challenges of capturing, processing and packaging radiogenic data for use in resolving chronological puzzles with which archaeologists has long wrestled. In practice, mobilizing radiogenic data for archaeological use is a hard-won achievement; it involves multiple transformations that, at each step of the way, depend upon a diverse array of technical expertise and background knowledge. I focus on strategies of triangulation and traceability that establish the integrity of these data and their relevance as anchors for evidential reasoning in archaeology. (shrink)
