Graphical AbstractScientists should learn to communicate effectively with their colleagues through long-term, sustained training instead of ad hoc, one-off “interventions” that may or may not occur during graduate school or postdoctoral work. Since such training may place unreasonable demands on research advisors, institutions should create career opportunities for “peer-peer communication teachers.”.

Although the terms mentor and thesis advisor (or research supervisor) are often used interchangeably, the responsibilities associated with these roles are distinct, even when they overlap. Neither are role models necessarily mentors, though mentors are role models: good examples are necessary but not sufficient. Mentorship is both a personal and a professional relationship. It has the potential for raising a number of ethical concerns, including issues of accuracy and reliability of the information conveyed, access, stereotyping and tracking of advisees, and (...) the abuse of power. Nevertheless, mentors can be critically important for professional success and are one of a number of elements that affect the responsible conduct of research. In addition, the community as a whole has a responsibility to mentor junior members. (shrink)

An important method for finding the optimal solution for linear and nonlinear models is the graphical method, which is used if the linear or nonlinear mathematical model contains one, two, or three variables. The models that contain only two variables are among the most models for which the optimal solution has been obtained graphically, whether these models are linear or non-linear in references and research that are concerned with the science of operations research, when the data of the issue under (...) study is classical data. In this research, we will present a study through, which we present the graphical method for solving Neutrosophical nonlinear models in the following case: A nonlinear programming issue, the objective function is a nonlinear function, and the constraints are linear functions. Note that we can use the same method if (i) the objective function follower is a linear follower and the constraints are nonlinear; (ii) the objective function is a non-linear follower and the constraints are non-linear. In the three cases, the nonlinear models are neutrosophic, and as we know, the mathematical model is a nonlinear model if any of the components of the objective function or the constraints are nonlinear expressions, and the nonlinear expressions may be in both. At the left end of the constraints are neutrosophic values, at least one or all of them. Then, the possible solutions to the neutrosophic nonlinear programming problem are the set of rays that fulfills all the constraints. As for the region of possible solutions, it is the region that contains all the rays that fulfill the constraints. The optimal solution is the beam that fulfills all constraints and at which the function reaches a maximum or minimum value, depending on the nature of the issue under study (noting that it is not necessary to be alone).

The paper has two goals. First, it defends one type of subjectivist account of reasons for actions—deliberative accounts—against the criticism that they commit the conditional fallacy. Second, it attempts to show that another type of subjectivist account of practical reasons that has been gaining popularity—ideal advisor accounts—are liable to commit a closely related error. Further, I argue that ideal advisor accounts can avoid the error only by accepting the fundamental theoretical motivation behind deliberative accounts. I conclude that ideal advisor accounts (...) represent neither a substantial departure from, nor a substantial improvement upon, deliberative accounts. (shrink)

Large language models (LLMs) represent the currently most relevant incarnation of artificial intelligence with respect to the future fate of democratic governance. Considering their potential, this paper seeks to answer a pressing question: Could LLMs outperform humans as expert advisors to democratic assemblies? While bearing the promise of enhanced expertise availability and accessibility, they also present challenges of hallucinations, misalignment, or value imposition. Weighing LLMs’ benefits and drawbacks compared to their human counterparts, I argue for their careful integration to (...) augment democracy’s ability to address complex policy issues. The paper posits that time-tested democratic procedures like deliberation and aggregation by voting provide safeguards effective against both human and machine advisor imperfections. Additional protective measures include custom LLM training for the advisory role, boosting representatives’ competencies in query formulation, or implementation of adversarial proceedings in which LLM advisors could debate each other and provide dissenting opinions. These could further mitigate the risks that LLMs present in advisory roles and empower human decision-makers toward increased autonomy and quality of their collective choices. My conceptual exploration offers a roadmap for the co-evolution of AI and democratic institutions, setting the stage for an empirical research agenda to finetune the implementation specifics.

This essay considers the ways in which graphic caregiving memoirs complicate the idealizing tendencies of ethics of care philosophy. The medium’s “capacious” layering of words, images, temporalities, and perspectives produces “productive tensions... The words and images entwine, but never synthesize”. In graphic memoirs about care, this “capaciousness” allows for quick oscillation between the rewards and struggles of care work, representing ambiguous, even ambivalent attitudes toward care. Graphic memoirs effectively represent multiple perspectives without synthesis, part of a structural and thematic ambivalence (...) that provides a provocative counterpart to the abstract idealism of ethics of care philosophy.

Through the lens of the Health Belief Model and Protection Motivation Theory, we analyzed interviews of 36 agricultural advisors in Indiana and Nebraska to understand their appraisals of climate change risk, related decision making processes and subsequent risk management advice to producers. Most advisors interviewed accept that weather events are a risk for US Midwestern agriculture; however, they are more concerned about tangible threats such as crop prices. There is not much concern about climate change among agricultural (...) class='Hi'>advisors. Management practices that could help producers adapt to climate change were more likely to be recommended by conservation and Extension advisors, while financial and crop advisors focused more upon season-to-season decision making. We contend that the agricultural community should integrate long-term thinking as part of farm decision making processes and that agricultural advisors are in a prime position to influence producers. In the face of increasing extreme weather events, climatologists and advisors should work more closely to reach a shared understanding of the risks posed to agriculture by climate change. (shrink)

The ArugmentThis essay answers a single question: what was Robert Hooke, the Royal Society's curator of experiments, doing in his well-known 1665 work,Micrographia?Hooke was articulating a “universal cure of the mind” capable of bringing about a “reformation in Philosophy,” a change in philosophy's interpretive practices and organization. The work explicated the interpretive and political foundations for a community of optical instrument users coextensive with the struggling Royal Society. Standard observational practices would overcome the problem of using nonstandard instruments, while inherent (...) inrepresentation– the interpretive practice championed in the text – were important theological and political meanings. Hooke's kind of experimental philosophy undermined the claims made by “atheists” and “enthusiasts” – the enemies of the restored church and state – while also producing useful knowledge. Equally important, Hooke modeled the community described inMicrographiaupon the classicalres publica, but his community made important concessions to Restoration political realities, especially the growing role of commercial or transactional relationships.

The article examines the place of graphic design in modern post-industrial society, extending beyond purely applied art and aspiring to play the role of an expert in the interiors of human existence, determining the social and cultural status of an individual. It is argued that graphic design, organically integrating into contexts and actively responding to the challenges of such a social-decorative phenomenon as fashion, plays a significant role in shaping taste culture. This attests to the multiplicity of ambivalent cultural manifestations (...) of graphic design. Special attention is given to identifying the functional potential of graphic design in creating cross-cutting trends that, through non-verbal means of communication, can form and maintain social and cultural unity. In connection with this, an analysis of graphic design is carried out through the prism of philosophical communication, allowing the identification of graphic design as the most effective practice of nonverbal communication and information visualization in post-industrial society. It is determined that graphic design is capable not only of generating new meanings but also of creating communicative gaps. Given this specificity, the article particularly focuses on identifying the educational and upbringing potential of graphic design. It is demonstrated that the process of creating visual images and their subsequent interpretation by consumers of graphic information depends not only on the aesthetic taste, ethical beliefs, and humanistic orientation of the designer (visualizer) but also on their educational and upbringing potential. The necessity of strengthening humanistic orientations in modern Ukrainian design and art education is emphasized. (shrink)

We describe a form of moral artificial intelligence that could be used to improve human moral decision-making. We call it the “artificial moral advisor”. The AMA would implement a quasi-relativistic version of the “ideal observer” famously described by Roderick Firth. We describe similarities and differences between the AMA and Firth’s ideal observer. Like Firth’s ideal observer, the AMA is disinterested, dispassionate, and consistent in its judgments. Unlike Firth’s observer, the AMA is non-absolutist, because it would take into account the human (...) agent’s own principles and values. We argue that the AMA would respect and indeed enhance individuals’ moral autonomy, help individuals achieve wide and a narrow reflective equilibrium, make up for the limitations of human moral psychology in a way that takes conservatives’ objections to human bioenhancement seriously, and implement the positive functions of intuitions and emotions in human morality without their downsides, such as biases and prejudices.

We present a theoretical framework bearing on the evolution of written communication. We analyze writing as a special kind of graphic code. Like languages, graphic codes consist of stable, conventional mappings between symbols and meanings, but (unlike spoken or signed languages) their symbols consist of enduring images. This gives them the unique capacity to transmit information in one go across time and space. Yet this capacity usually remains quite unexploited, because most graphic codes are insufficiently informative. They may only be (...) used for mnemonic purposes or as props for oral communication in real-time encounters. Writing systems, unlike other graphic codes, work by encoding a natural language. This allows them to support asynchronous communication in a more powerful and versatile way than any other graphic code. Yet, writing systems will not automatically unlock the capacity to communicate asynchronously. We argue that this capacity is a rarity in non-literate societies, and not so frequent even in literate ones. Asynchronous communication is intrinsically inefficient because asynchrony constrains the amount of information that the interlocutors share and limits possibilities for repair. This would explain why synchronous, face-to-face communication always fosters the development of sophisticated codes (natural languages), but similar codes for asynchronous communication evolve with more difficulties. It also implies that writing cannot have evolved, at first, for supporting asynchronous communication. (shrink)

A graphic means of representing deductive proofs in a sentential system of symbolic logic is presented. Proof construction is characterized as a domain of the cognitive theory of problem solving, and three different interface designs for supporting the working backwards method of proof construction are demonstrated. Following a description of the rule set and the working backwards method, an analysis is given of student performance data that has guided interface development during the past two years. One interface design is shown (...) to be superior to the others in respect to working backwards. Finally, some general conclusions are drawn concerning the relevance of instructional programs for empirically documenting student difficulties and for improving interface designs. (shrink)

Professor Mitt Regan takes up Brad Wendel's suggestion that we have to distinguish the ethics of advocates from those which guide other forms of legal work, and proposes that the distinction be taken further. Legal advising can itself implicate different ethical positions. Regan concentrates on tax advisers, and argues that their work can, at times, legitimately require a partisan advocate's stance in the giving of tax advice or an impartial trustee's stance in ensuring that the spirit, as well as the (...) letter, of tax law is honoured. Especially in the US, there are strong systemic justifications for treating the tax adviser as an advocate: the wide latitude that tax law gives the citizen when calculating tax liability, the hazards of accurate interpretation of the tax code, and the need for predictability in client arrangements suggesting that it is preferable to concentrate strictly on the letter of the law. So too, the tax adviser as trustee is informed by the importance of tax collection for ordinary government services, and by 'tax morale' and the community's confidence in the tax system generally. The bifurcation of ethical stances in tax advising is, as a consequence, a function of the 'conflicted regulation' of citizen taxpayers. (shrink)

Richard Rudner famously argues that the communication of scientific advice to policy makers involves ethical value judgments. His argument has, however, been rightly criticized. This article revives Rudner’s conclusion, by strengthening both his lines of argument: we generalize his initial assumption regarding the form in which scientists must communicate their results and complete his ‘backup’ argument by appealing to the difference between private and public decisions. Our conclusion that science advisors must, for deep-seated pragmatic reasons, make value judgments is (...) further bolstered by reflections on how the scientific contribution to policy is far less straightforward than the Rudner-style model suggests.

Graphical models are a powerful tool for causal model specification. Besides allowing for a hierarchical representation of variable interactions, they do not require any a priori specification of the functional dependence between variables. The construction of such graphs hence often relies on the mere testing of whether or not model variables are marginally or conditionally independent. The identification of causal relationships then solely requires some general assumptions on the relation between stochastic and causal independence, such as the Causal Markov Condition (...) and the Faithfulness Condition (Spirtes et al. 2000; Pearl 2000). However, a procedure would require further assumptions to hold. Namely those the independence tests themselves are based on. In continuous settings, Spirtes et al. (2000) suggest causal inference based on a very restrictive formulation of independence, that is, vanishing partial correlations. Such a measure does, however, limit the applicability of causal inference to linear systems. This constitutes a serious drawback especially for the social sciences where an a priori specification of the functional form proves difficult or at odds with linearity. In short: graphical models theoretically reduce specification uncertainty regarding functional dependence, but their implementation in practice deprives them of this virtue. In this paper we investigate how causal structures in continuous settings can be identified when both functional forms and probability distributions of the variables remain unspecified. We focus on tests exploiting the fact that if X and Y are conditionally independent given a set of variables Z, the two conditional densities f (X|Y, Z) and f (X|Z) must coincide. We start by estimating the conditional densities f(X|Y, Z) and f(X|Z) via nonparametric techniques (kernel methods). We proceed by testing if some metric expressing the distance between these very conditional densities is sufficiently close to zero. Out of several metrics available in the literature to express such distance we choose two, the Euclidean, and the Hellinger distance. We investigate in a Monte Carlo study how different tests involving either measure are able to detect statistical independence, conditioned on a small set of variables. One limitation may result from nonparametric density estimation being subject to the curse of dimensionality. As the number of variables increases, the estimated empirical density converges at a slower rate to its population value. To compensate this drawback we use a local bootstrap procedure which consists of resampling the data for each test. While local bootstrap strongly increases the computational time of the test, it succeeds in counterbalancing the curse of dimensionality. (shrink)

Questions concerning mediated causal effects are of great interest in psychology, cognitive science, medicine, social science, public health, and many other disciplines. For instance, about 60% of recent papers published in leading journals in social psychology contain at least one mediation test (Rucker, Preacher, Tormala, & Petty, 2011). Standard parametric approaches to mediation analysis employ regression models, and either the “difference method” (Judd & Kenny, 1981), more common in epidemiology, or the “product method” (Baron & Kenny, 1986), more common in (...) the social sciences. In this article, we first discuss a known, but perhaps often unappreciated, fact that these parametric approaches are a special case of a general counterfactual framework for reasoning about causality first described by Neyman (1923) and Rubin (1924) and linked to causal graphical models by Robins (1986) and Pearl (2006). We then show a number of advantages of this framework. First, it makes the strong assumptions underlying mediation analysis explicit. Second, it avoids a number of problems present in the product and difference methods, such as biased estimates of effects in certain cases. Finally, we show the generality of this framework by proving a novel result which allows mediation analysis to be applied to longitudinal settings with unobserved confounders. (shrink)

The article explores the demands that the conflictual dimension of globalization poses for a cosmopolitan education. Such an emphasis seems necessary in times where the populations who undertake inter- and intra-national border crossings are increasingly those who are forced to: those trying to escape unbearable poverty, atrocious wars, the disenfranchised and victims of racist, sexist or religious persecution. Reflecting on the experiences articulated in the two graphic novels, Persepolis and American Born Chinese, the dimension of the globalizing world and its (...) impact and demands on its future world citizens which comes to the fore is one that highlights the necessity for learning how to take a critical and political stance rather than the search for how education can facilitate a smooth adaptation to a new mobile order. Stanley Cavell’s examination of the relationship between autobiography, philosophy, and the founding of a self-reliant voice will be reconsidered in light of its contribution to re-thinking the meaning of a cosmopolitan education between critical self-appropriation and developing a transformative political vision of a new societal order.

Part of Allen et al.’s criticism of Hamilton’s rule makes sense only if we are interested in social adaptation rather than merely social selection. Under the assumption that we are interested in casually modeling social adaptation, I illustrate how graphical causal models of social adaptation can be useful for predicting evolution by adaptation. I then argue for two consequences of this approach given some of the recent philosophical literature. I argue Birch’s claim that the proper way to understand Hamilton’s rule (...) is as providing an organizational framework for causal models is incorrect. I provide an account of a causally adequate decomposition of evolutionary change due to social adaptation and show that my account is superior to Okasha’s. (shrink)

The linear programming method is one of the important methods of operations research that has been used to address many practical issues and provided optimal solutions for many institutions and companies, which helped decision makers make ideal decisions through which companies and institutions achieved maximum profit, but these solutions remain ideal and appropriate in If the conditions surrounding the work environment are stable, because any change in the data provided will affect the optimal solution and to avoid losses and achieve (...) maximum profit, we have, in previous research, reformulated the linear models using the concepts of neutrosophic science, the science that takes into account the instability of conditions and fluctuations in the work environment and leaves nothing to chance. While taking data, neutrosophic values carry some indeterminacy, giving a margin of freedom to decision makers. In another research, we reformulated one of the most important methods used to solve linear models, which is the simplex method, using the concepts of this science, and as a continuation of what we did in the previous two researches, we will reformulate in this research. The graphical method for solving linear models using the concepts of neutrosophics. We will also shed light on a case that is rarely mentioned in most operations research references, which is that when the difference between the number of unknowns and the number of constraints is equal to one, two, or three, we can also find the optimal solution graphically for some linear models. This is done by taking advantage of the conditions of non-negativity that linear models have, and we will explain this through an example in which the difference is equal to two. Also, through examples, we will explain the difference between using classical values and neutrosophic values and the extent of this’s impact on the optimal solution. (shrink)

Music may have a strong influence on literature. Many novels have reflected this by thematizing music in many different ways. However, this engagement can also adopt the form of an imitation or a formal presence that does not actually require the text to say anything about music. This paper aims to explore some aspects of musical imitation in literature that have not been analyzed in depth. Departing from the approach developed by Werner Wolf, I propose a distinction between imitating and (...) imitated elements that applies to any case of study. Furthermore, at the core of this article, I advocate for a fourth dimension that the imitation of music in literature may have and that should be added to word music, formal and structural analogies, and imaginary content analogies. I call this fourth category “graphic analogies.” It implies an imitation whose imitating element is the graphic, written aspect of the linguistic signifier. Finally, this leads to the idea that, in the case of the imitation of music in literature, there is not a necessary correlation between imitating and imitated elements. (shrink)

Medthics is an online graphic novel series comprising of six issues . What is often viewed as pop culture escapism, this "comic book" series tackles the complex world of medicine and its moral/ethical intricacies. From topics about physician identity formation to humane patient care, Medthics brings to the forefront subject matter essential to clinical practice. The art of medicine is depicted through stylized characters as they live their lives through a fictional world inspired by true events.

Comics has always had a critical engagement with socio-political and cultural issues and hence evolved into a medium with a subversive power to challenge the status quo. Staying true to the criticality of the medium, graphic medicine critiques the exploitative and unethical practices in the field of healthcare, thereby creating a critical consciousness in the reader. In close reading select graphic pathographies such as Gabby Schulz's Sick, Emily Steinberg's Broken Eggs, Ellen Forney's Marbles: Mania, Depression, Michelangelo & Me and Marisa (...) Marchetto's Cancer Vixen, the present article delineates how graphic medicine interrogates the larger than life forces in the field of healthcare. Drawing specific instances from the aforementioned graphic texts, the essay demonstrates that graphic medicine scrutinizes the political economy of health under capitalism. In so doing, the article illustrates how the pharmaceutical corporations, insurance companies, medical technology, and healthcare corporations marketize and commoditize health in the neoliberal era. Finally, the article attempts to theorize how graphic pathographies, mediating subjective experiences, generate a new critical literacy through the conflation of the personal and the political in the verbovisual medium of comics.

The emergence of shared symbol systems is considered to be a pivotal moment in human evolution and human development. These changes are normally explained by reference to changes in people's internal cognitive processes. We present 2 experiments which provide evidence that changes in the external, collaborative processes that people use to communicate can also affect the structure and organization of symbol systems independently of cognitive change. We propose that mutual‐modifiability—opportunities for people to edit or manipulate each other's contributions—is a key (...) constraint on the emergence of complex symbol systems. We discuss the implications for models of language development and the origins of compositionality. (shrink)

A patient arrives in the emergency room apparently in a comatose state. But is he really unconscious or just faking? The young doctors on duty are skeptical. Failing to get a reaction with a chest rub, they try a variety of methods that become increasingly sadistic—pressing on the patient's fingernail with a ballpoint pen, spraying his testicles with a skin‐freezing compound, announcing an imminent eye injection to scare the patient awake.I first encountered those chilling pen‐and‐ink images in a 2012 comic (...) book, Disrepute, authored by Thom Ferrier, the nom de plume for British general practitioner Ian Williams. Disrepute is part of a young but growing genre that Williams helped dub "graphic medicine" when he founded a website by that name in 2007. Using the graphic novel form, doctors, nurses, and patients are producing accounts that often reveal the dark underbelly of the world of medicine. From patients and their families, these include portraits of imperious and insensitive physicians or nurses; from doctors, explorations of the doubt that racks them when their treatment ends in a mistake or a patient's death. While the form is also referred to as “comics,” the work, as in Williams's strip, is bleak just as often as it is humorous. (shrink)

In this paper, we propose two four-base related 2D curves of DNA primary sequences and their corresponding single-base related 2D curves. The constructions of these graphical curves are based on the assignments of individual base to four different sinusoidal functions; then by connecting all these points on these four sinusoidal functions, we can get the F-B curves; similarly, by connecting the points on each of the four sinusoidal functions, we get the single-base related 2D curves. The proposed 2D curves are (...) all strictly non degenerate. Then, a 8-component characteristic vector is constructed to compare similarity among DNA sequences from different species based on a normalized geometrical centers of the proposed curves. As examples, we examine similarity among the coding sequences of the first exon of beta-globin gene from eleven species, similarity of cDNA sequences of beta-globin gene from eight species, and similarity of the whole mitochondrial genomes of 18 eutherian mammals. The experimental results well demonstrate the effectiveness of the proposed method. (shrink)

Reporting systems based on mobile technologies and feedback from regular citizens are becoming increasingly popular, especially as far as protection of environmental and cultural heritage is concerned. Reporting life-threatening situations, such as sudden natural disasters or traffic accidents, belongs to the same class of problems and could be aided by IT systems of a similar architecture. Designing and developing systems for reporting life-threatening situations is not a trivial task, requiring close cooperation between software developers and experts in different domains, who (...) could possibly find industrially recognized languages and notations difficult. Thus, the question is whether using simplified graphical domain-specific languages (SGDSLs) could help in creating a common communication platform. It has been revealed that domain experts have a preference for such languages as they offer good learnability, readability and ability to focus on the idea of application. The perspective of developers (technical persons) is introduced on the basis of feedback obtained from 84 students of Computer Science at the Lublin University of Technology, who attended comprehensive workshops followed by an anonymous survey. All participants received theoretical and practical training in modeling mobile software using the same set of languages as domain experts. An analysis of the results revealed that opinions expressed by technical and nontechnical persons concerning SGDSLs oriented on defining a flow of actions is consistent. Most respondents claimed that such languages might be valuable as tools for creating a common communication platform. (shrink)

Robustness has long been recognized as an important parameter for evaluating game-theoretic results, but talk of ‘robustness’ generally remains vague. What we offer here is a graphic measure for a particular kind of robustness (‘matrix robustness’), using a three-dimensional display of the universe of 2 × 2 game theory. In such a measure specific games appear as specific volumes (Prisoner’s Dilemma, Stag Hunt, etc.), allowing a graphic image of the extent of particular game-theoretic effects in terms of those games. The (...) measure also allows for an easy comparison between different effects in terms of matrix robustness. Here we use the measure to compare the robustness of Tit for Tat’s well-known success in spatialized games (Axelrod, R. (1984). The evolution of cooperation . New York: Basic Books; Grim, P. et al. (1998). The philosophical computer: Exploratory essays in philosophical computer modeling .

A new vectorial representation for the successive Lorentz transformations has recently been proved very convenient to achieve a straightforward treatment of the Thomas rotation effect. Such a representation rests on equivalent forms for the pure Lorentz transformation and SLT whose physical meaning escaped us. The present paper fills this gap in by showing that those equivalent forms could represent appropriate world lines, lines and planes of simultaneity. Those geometric elements are particularly convenient to build up two new graphical representations for (...) the SLT: the first rests on that equivalent form for the SLT, while the second takes the SLT as a PLT preceded or followed by a Thomas rotation and uses the equivalent form for the PLT. As an application, the SLT Lorentz contraction formulas are derived for the first time. The dependence of the SLTLC on the Thomas rotation is put in evidence. The SLTLC along directions transverse and parallel to the composite velocity is studied. Original SLT Minkowski diagrams are given for the first time. (shrink)

In her recent article, ‘Internalism About Reasons: Sad But True?,’ Kate Manne offers a brilliant defense of a novel version of internalism about normative reasons. But I will argue that this defense is not successful. After explaining the nature of Manne’s internalism, I offer two counterexamples to it, thereby showing that her argument in its favor goes wrong somewhere. I then identify the false premise in her argument. In brief, I suggest that Manne’s ‘practice-based approach’ to practical normativity (or at (...) least, to normative reasons) should be rejected.
