Complex systems are difficult to manage, operate and maintain. This is why we see teams of highly specialised engineers in industries such as aerospace, nuclear and subsurface. Condition based monitoring is also employed to maximise the efficiency of extensive maintenance programmes instead of using periodic maintenance. A level of automation is often required in such complex engineering platforms in order to effectively and safely manage them. Advances in Artificial Intelligence related technologies have offered greater levels of automation but this potentially (...) pivots the weight of decision making away from the operator to the machine. Implementing AI or complex algorithms into a platform can mean that the Operators’ control over the system is diminished or removed altogether. For example, in the Boeing 737 Air Max Disaster, AI had been added to a platform and removed the operators’ control of the system. This meant that the operator could not then move outside the extremely reserved, algorithm defined, “envelope” of operation. This paper analyses the challenges of AI driven condition based monitoring where there is a potential to see similar consequences to those seen in control engineering. As the future of society becomes more about algorithm driven technology, it is prudent to ask, not only whether we should implement AI into complex systems, but how this can be achieved ethically and safely in order to reduce risk to life.

Sometimes, a form of discrimination is hard to register, understand, and articulate. A rich precedent demonstrates how victim testimonies have been key in uncovering such “hidden” forms of discrimination, from sexual harassment to microaggressions. I reflect on how this plausibly goes too for “attentional discrimination”, referring to cases where the more meaningful attributes of one social group are made salient in attention in contrast to the less meaningful attributes of another. Victim testimonies understandably dominate the “context-of-discovery” stage of research into (...) these initially opaque forms of discrimination; a victim’s encounter with the gap between their experience and dominant conceptual frameworks for understanding it is what provides an initial foothold for analysis to begin. Some object, however, to this methodology continuing to dominate the later “context-of-justification” stage, where the hypothesis is rigorously challenged. I argue that this objection underestimates not just how other methodologies are more likely to inherit the various mechanisms of invisibility hiding the discrimination in question, but also how victim testimonies are distinctively well-suited to recognize and challenge those mechanisms. Victim testimonies, then, ought to continue playing a dominant role into these later stages of research regarding hidden forms of discrimination. (shrink)

Abstract Gene-selectionists define fundamental terms in non-standard ways. Genes are determinants of difference. Phenotypes are defined as a gene’s effects relative to some alternative whereas the environment is defined as all parts of the world that are shared by the alternatives being compared. Environments choose among phenotypes and thereby choose among genes. By this process, successful gene sequences become stores of information about what works in the environment. The strategic gene is defined as a set of gene tokens that combines (...) ‘actor’ tokens responsible for an effect with ‘recipient’ tokens whose replication is thereby enhanced. This set of tokens can extend across the boundaries of individual organisms, or other levels of selection, as these are traditionally defined.

David Haig propounds and illustrates the unity of a radically revised set of definitions of the family of terms at the heart of philosophy of cognitive science and mind: information, meaning, interpretation, text, choice, possibility, cause. This biological re-grounding of much-debated concepts yields a bounty of insights into the nature of meaning and life. An interpreter is a mechanism that uses information in choice. The capabilities of the interpreter couple an entropy of inputs to an entropy of outputs is (...) dispelled by observation. The second entropy is dispelled. I propose that an interpreter’s response to inputs meaning of the information for the interpreter. In this conceptual framework, the mechanisms of interpreters provide the much-debated link between Shannon information and semantics. (shrink)

August Weismann rejected the inheritance of acquired characters on the grounds that changes to the soma cannot produce the kind of changes to the germ-plasm that would result in the altered character being transmitted to subsequent generations. His intended distinction, between germ-plasm and soma, was closer to the modern distinction between genotype and phenotype than to the modern distinction between germ cells and somatic cells. Recently, systems of epigenetic inheritance have been claimed to make possible the inheritance of acquired characters. (...) I argue that the sense in which these claims are true does not challenge fundamental tenets of neo-Darwinism. Epigenetic inheritance expands the range of options available to genes but evolutionary adaptation remains the product of natural selection of ‘random’ variation. (shrink)

The High Court is taking an increasingly important role in shaping the contours of democracy in Australia. In deciding fundamental democratic questions, does the Court pursue a consistent and overarching democratic vision? Or are its decisions essentially constrained by institutional and practical limitations? Judging Democracy, first published in 2000, addresses this question by examining the Court's recent decisions on human rights, citizenship, native title and separation of powers. It represents the first major political and legal examination of the Court's new (...) jurisprudence and the way it is influencing democracy and the institutions of governance in Australia. A foreword to the book has been written by the former Chief Justice of the High Court, Sir Anthony Mason. (shrink)

Consider a terrible situation that too many women find themselves in: 85,000 women are raped in England and Wales alone every year. Many of these women do not bring their cases to trial. There are multiple reasons that they might not want to testify in the courts. The incredibly low conviction rate is one. Another reason, however, might be that these women do not want the fact that they were raped to become the most salient thing about them. More specifically, (...) they do not want it to be the thing that others attend to the most—that others find most noticeable and memorable. In this paper, I introduce the notion of ‘harmful salience perspectives’ to help to explain this and related phenomena. This refers either to attention on things that should not be salient, or not enough attention on things that deserve to be made salient. Following ideas within the feminist literature on objectification, I argue that we can be harmed when aspects of our identity that do not reflect our personhood—our agency, rationality, personality, and so on—are more prominent in the minds of others than aspects that do reflect our personhood. Crucially, these ways of attending do not need to implicate false beliefs and harmful ideologies to be harmful, but can be harmful in their own right. (shrink)

Modern honor appears to be distinguished by two contradictory impulses, a neglect or even disdain of honor, and an ambition to elevate and promote it as dignity, self-esteem, and recognition. The article argues that these tensions can be traced to a foundational difference regarding the political importance of the passion of honor, evident in the seminal and contending formulations by Machiavelli and Hobbes. In recovering and articulating the bases of these competing modern conceptions of honor and tracing the influence of (...) their divergent trajectories, the article seeks to show the importance of honor for understanding contemporary politics.

John Locke is acknowledged to be one of the theoretical founders of the separation of church and state, a distinguishing feature of modern liberal democracies. Though Locke’s arguments for the merits of such separation have been subject to extensive investigation, his argument for its feasibility has remained relatively unexamined. This article argues that Locke was confident that separation of church and state can successfully be implemented in all times and places because of his epistemological and psychological insights that human beings (...) are moved to act by unease and that separating church and state removes the unease that causes religiously based political instability. We conclude by noting that Locke’s understanding of unease is foundational for his larger ambition to secure political liberty. (shrink)

One theme in complaints from those with marginalized social identities is that they are seen primarily in terms of that identity. Some Black artists, for instance, complain about being seen as Black first and artists second. These individuals can be understood as objecting to a particularly subtle form of morally problematic attention: “relative attentional surplus on the wrong property.” This attentional surplus can coexist with another type of common problematic attention affecting these groups, including attentional deficits; marginalized individuals and groups (...) themselves are routinely insufficiently attended to in virtue of the surplus attention given to their social identity properties.

The Philosophy of Quantitative Methods undertakes a philosophical examination of a number of important quantitative research methods within the behavioral sciences in order to overcome the non-critical approaches typically provided by textbooks. These research methods are exploratory data analysis, statistical significance testing, Bayesian confirmation theory and statistics, meta-analysis, and exploratory factor analysis. Further readings are provided to extend the reader's overall understanding of these methods.

Whenever we communicate, we inevitably have to say one thing before another. This means introducing particularly subtle patterns of salience into our language. In this paper, I introduce ‘order-based salience patterns’, referring to the ordering of syntactic contents where that ordering, pretheoretically, does not appear to be of consequence. For instance, if one is to describe a colourful scarf, it wouldn’t seem to matter if one were to say it is ‘orange and blue’ or ‘blue and orange’. Despite their apparent (...) triviality, I argue that order-based salience patterns tend to make the content positioned first more salient – in the sense of attention-grabbing – in a way that can have surprising normative implications. Giving relative salience to gender differences over similarities, for instance, can result in the activation of cognitively accessible beliefs about gender differences. Where those beliefs are epistemically and/or ethically flawed, we can critique the salience pattern that led to them, providing an instrumental way of evaluating those patterns. I suggest that order-based salience patterns can also be evaluated on constitutive grounds; talking about gender differences before similarities might constitute a subtle form of bias. Finally, I reflect on how the apparent triviality of order-based salience patterns in language gives them an insidious strength. (shrink)

Learning to adapt to the new set of conditions that confound behavioral standards was made possible by the pandemic-driven change in the school system. Due to these conditions and the COVID-19 pandemic, students may experience behaviors like social media addiction and social anxiety that may affect their well-being or happiness. Thus, this study aims to investigate the effects of social media addiction and social anxiety on the happiness of tertiary students amidst the COVID-19 pandemic. The study was conducted on 316 (...) first-year college students utilizing Google forms to disseminate questionnaires. After utilizing Bergen Social Media Addiction Scale, Social Anxiety Scale, and Oxford Happiness Questionnaire, it was found that social media addiction (β = -0.30, p<.00) and social anxiety (β = -0.003, p<.00) has a significant negative effect on happiness. Therefore, the study recommended and designed a student wellness program that provides a range of recreational, healthimproving, self-esteem-boosting, and relationship-strengthening activities for students in order to mitigate the negative effects of problematic social media usage and social anxiety that negatively effect their happiness.

Hobbes's understanding of love, and its significance for his political thought, has received insufficient attention. This essay contends that Hobbes has a consistent and comprehensive teaching on love that directly repudiates what he regards as the Platonic teaching on eros. In attacking the Platonic idea of eros, Hobbes undermines a pillar of classical political philosophy and articulates a significant aspect of his new understanding of the passions in terms of power, which is itself a critical part of his new political (...) science most famously presented in Leviathan.

Therefore, it is appropriate to evaluate his undertaking, not only in terms of its teaching, but also in the success of its rhetorical ambition. 1I argue in this paper that Hobbesian rhetoric is fundamentally determined by his political theory, in particular, by his discovery of the problem of vaine-glory, or pride. Pride poses a political problem because it is a passion that produces an unrealistic estimation of our abilities and therefore ultimately leads to deadly struggles and war.

This argument about the rhetorical character of the first part of the Leviathan has important theoretical consequences: it suggests that Hobbes's influential formulation of power, rights, and justice also had a profoundly rhetorical character.But how persuasive is Hobbes's rhetoric? For reasons noted above, this question goes to the heart of his political theory. The final part of this paper explores the efficacy of the Hobbesian rhetoric of pride and therefore of Hobbesian science. I argue that the rhetorical descent in the first part of the Leviathan, where the truth about human weakness is revealed to the proud, is simultaneously an ascent that acknowledges independence and self-sufficiency of human beings as "self-makers." Thus I argue that, rather than overcoming the problem of pride, Hobbesian political science re-founds it on the bases of rights and the promise of unlimited progress through science and commerce: Hobbes's rhetoric reformulated, but did not solve, the problem of pride.

Recent scandals allegedly linked to CEO compensation have brought executive compensation and perquisites to the forefront of debate about constraining executive compensation and reforming the associated corporate governance structure. We briefly describe the structure of executive compensation, and the agency theory framework that has commonly been used to conceptualize executives acting on behalf of shareholders. We detail some criticisms of executive compensation and associated ethical issues, and then discuss what previous research suggests are likely intended and unintended consequences of some (...) widely proposed executive compensation reforms. We explicitly discuss the following recommendations for reform: require greater independence of compensation committees, require executives to hold equity in the corporation, require greater disclosure of executive compensation, increase institutional investor involvement in corporate governance (including executive compensation), and require firms to expense stock options on their income statements. We provide a brief summary discussion of ethical issues related to executive compensation, and describe possible future research. (shrink)

Asay (2018) criticizes our contention that psychologists do best to adhere to a substantive theory of correspondence truth. He argues that deflationary theory can serve the same purposes as correspondence theory. In the present article we argue that (a) scientific realism, broadly construed, requires a version of correspondence theory and (b) contrary to Asay’s suggestion, correspondence theory does have important additional resources over deflationary accounts in its ability to support generalizations over classes of true sentences.

Organisms can be treated as optimizers when there is consensus among their genes about what is best to be done, but genomic consensus is often lacking, especially in interactions among kin because kin share some genes but not others. Grafen adopts a majoritarian perspective in which an individual’s interests are identified with the interests of the largest coreplicon of its genome, but genomic imprinting and recombination factionalize the genome so that no faction may predominate in some interactions among kin. Once (...) intragenomic conflicts are recognized, the individual organism can be conceptualized as an arbiter among competing interests within a collective. Organismal adaptation can be recognized without phenotypes being optimized. (shrink)

Mitochondria exist in large numbers per cell. Therefore, the strength of natural selection on individual mtDNAs for their contribution to cellular fitness is weak whereas the strength of selection in favor of mtDNAs that increase their own replication without regard for cellular functions is strong. This problem has been solved for most mitochondrial genes by their transfer to the nucleus but a few critical genes remain encoded by mtDNA. Organisms manage the evolution of mtDNA to prevent mutational decay of essential (...) services mitochondria provide to their hosts. Bottlenecks of mitochondrial numbers in female germlines increase the homogeneity of mtDNAs within cells and allow intraorganismal selection to eliminate cells with low quality mitochondria. Mechanisms of intracellular “quality control” allow direct selection on the competence of individual mtDNAs. These processes maintain the integrity of mtDNAs within the germline but are inadequate to indefinitely maintain mitochondrial function in somatic cells. (shrink)

The germ track is the cellular path by which genes are transmitted to future generations whereas somatic cells die with their body and do not leave direct descendants. Transposable elements (TEs) evolve to be silent in somatic cells but active in the germ track. Thus, the performance of most bodily functions by a sequestered soma reduces organismal costs of TEs. Flexible forms of gene regulation are permissible in the soma because of the self‐imposed silence of TEs, but strict licensing of (...) transcription and translation is maintained in the germ track to control proliferation of TEs. Delayed zygotic genome activation (ZGA) and maternally inherited germ granules are adaptations that enhance germ‐track security. Mammalian embryos exhibit very early ZGA associated with extensive mobilization of retroelements. This window of vulnerability to retrotransposition in early embryos is an indirect consequence of evolutionary conflicts within the mammalian genome over postzygotic maternal provisioning. (shrink)

In the philosophy of language and epistemology, debates often centre on what content a person is communicating, or representing in their mind. How that content is organised, along dimensions of salience, has received relatively little attention. I argue that salience matters. Mere change of salience patterns, without change of content, can have dramatic implications, both epistemic and moral. Imagine two newspaper articles that offer the same information about a subject, but differ in terms of what they headline. These articles can (...) be said to adopt different linguistic salience perspectives. Making different things salient in language is a way of making different things salient in an audience’s mind: it is a way of encouraging the audience to adopt a particular cognitive salience perspective. Building on Elisabeth Camp’s work on perspectives, and Sebastian Watzl’s work on attention, I suggest that one has a certain cognitive salience perspective in virtue of better noticing, remembering, and finding cognitively accessible certain contents over others. Drawing on psychological research into cognitive biases and framing effects, I argue that that simply making some content salient in the mind, perhaps through first making it salient in language, can be sufficient to activate substantive cultural beliefs or ideologies associated with that content. Where those beliefs and ideologies have epistemic and moral problems, we have grounds for criticising the salience perspective that causally produced them. Besides this instrumental harm, I also suggest that certain salience perspectives can themselves constitute harm. I draw on feminist work on objectification to argue that making the wrong thing salient about a person can constitute a way of dehumanising them. A great many factors, from physical and psychological violence, to false beliefs and credibility deficits, have already been identified as potentially harming an individual or group. What is distinctive about this argument, then, is the idea that, sometimes, mere patterns of salience can be damaging in and of themselves. (shrink)

Organisms and their genomes are mosaics of features of different evolutionary age. Older features are maintained by ‘negative’ selection and comprise part of the selective environment that has shaped the evolution of newer features by ‘positive’ selection. Body plans and body parts are among the most conservative elements of the environment in which genetic differences are selected. By this process, well-trodden paths of development constrain and direct paths of evolutionary change. Structuralism and adaptationism are both vindicated. Form plays a selective (...) role in the molding of form. (shrink)

Concepts of cause, choice, and information are closely related. A cause is a choice that can be held responsible. It is a difference that makes a difference. Information about past causes and their effects is a valuable commodity because it can be used to guide future choices. Information about criteria of choice is generated by choosing a subset from an ensemble for ‘reasons’ and has meaning for an interpreter when it is used to achieve an end. Natural selection evolves interpreters (...) with ends. Surviving genes embody a textual record of past choices that had favorable outcomes. Consultation of these archives guides current choices. Purposive choice is well-informed difference making. (shrink)

RNAs can do many things. They can store information, act in the world, and respond to the world. Because of these capabilities biologists have proposed a primordial ‘RNA world’ in which RNA, rather than DNA, performed the central role of replicator and repository of adaptive information. Deacon dismisses this hypothesis because replication is not about anything and because the structure of replicating molecules cannot contain information about the environment. I dispute both claims. An RNA and its opposite-sense complement represent each (...) other and, by two rounds of complementation, represent themselves. Although nucleic acid sequences do not change in response to their present environment, these sequences embody information about ancestral environments via the selective filtering of alternative sequences in those environments. Nucleic acid sequences are the textual record of what has worked in the past. (shrink)

Most eukaryotes possess many copies of rDNA. Organismal selection alone cannot maintain rRNA function because the effects of mutations in one rDNA are diluted by the presence of many other rDNAs. rRNA quality is maintained by processes that increase homogeneity of rRNA within, and heterogeneity among, germ cells thereby increasing the effectiveness of cellular selection on ribosomal function. A successful rDNA repeat will possess adaptations for spreading within tandem arrays by intranuclear selection. These adaptations reside in the non‐coding regions of (...) rDNA. Single‐copy genes are predicted to manage processes of intranuclear and cellular selection in the germline to maintain the quality of rRNA expressed in somatic cells of future generations. (shrink)
