The H ∞ performance of a class of T-S fuzzy systems with Markovian-jump parameters is analyzed. A state feedback controller is designed for T-S fuzzy systems with Markovian-jump parameters. First, a new modal-dependent Lyapunov function composed of closed-loop functions is constructed, which can fully use system status information. Based on this function, the stability conditions with less conservatism are given by linear matrix inequalities. At the same time, a design algorithm for a state feedback controller is proposed for the Markovian-jump-parameters (...) T-S fuzzy systems, which ensures the system’s stability under the condition of H ∞ − γ performance. Simulation results demonstrate that the mentioned method is accurate and practical. (shrink)

In the complex environment, the suddenly changing structural parameters and abrupt actuator failures are often encountered, and the negligence or unproper handling method may induce undesired or unacceptable results. In this paper, taking the suddenly changing structural parameters and abrupt actuator failures into consideration, we focus on the robust adaptive control design for a class of heterogeneous Takagi–Sugeno fuzzy nonlinear systems subjected to discontinuous multiple uncertainties. The key point is that the switch modes not only vary with the system (...) time but also vary with the system states, and the intrinsic heterogeneous characteristics make it difficult to design stable controllers. Firstly, the concepts of differential inclusion are introduced to describe the heterogeneous fuzzy systems. Meanwhile, a fundamental lemma is provided to demonstrate the criteria of the boundness for a Filippov solution. Then, by using the set-valued Lie derivative of the Lyapunov function and introducing a vector of specific continuous functions, the closed-loop T-S fuzzy differential inclusion systems are proved to be ultimately bounded. The sufficient conditions for system stability are derived in term of linear matrix inequalities, which can be solved directly. Finally, a numerical example is provided to illustrate the effectiveness of the proposed control algorithm. (shrink)

A fuzzy predictive fault-tolerant control scheme is proposed for a wide class of discrete-time nonlinear systems with uncertainties, interval time-varying delays, and partial actuator failures as well as unknown disturbances, in which the main opinions focus on the relevant theory of FPFTC based on Takagi-Sugeno fuzzy model description of these systems. The T-S fuzzy model represents the discrete-time nonlinear system in the form of the discrete uncertain time-varying delay state space, which is firstly constructed by a set of local (...) linear models and the nonlinear membership functions. The novel improved state space model can be further obtained by extending the output tracking error to the constructed model. Then the fuzzy predictive fault-tolerant control law based on this extended model is designed, which can increase more control degrees of freedom. Utilizing Lyapunov-Krasovskill theory, less conservative delay-range-dependent stable conditions in terms of linear matrix inequality constraints are given to ensure the asymptotically robust stability of closed-loop system. Meanwhile, the optimized cost function and H-infinity performance index are introduced to the stable conditions to guarantee the robust performance and antidisturbance capability. The simulation results on the temperature control of a strong nonlinear continuous stirred tank reactor show that the proposed control scheme is feasible and effective. (shrink)

On the surface, it seems plausible that the goodness or badness of an agent’s actions should be completely irrelevant to the question of whether she performed them intentionally, but there is growing evidence that ascriptions of intentional actions are affected by moral considerations. Joshua Knobe, for instance, has recently published a series of groundbreaking papers (2003a, 2003b, 2004) in which he suggests that people’s judgments concerning the intentionality of an action may sometimes depend on what they think about the action (...) – morally speaking. One of the more interesting results of Knobe’s psychological experiments is the discovery that people may have a lower threshold for judging that lucky (or unskilled) actions are intentional when these actions are praiseworthy or blameworthy than they do for judging that equally lucky (or unskilled) morally neutral actions are intentional. In this paper I show that this discovery – when supplemented with some additional empirical data – gives us a way of shedding new light on a controversy that was sparked by Ronald Butler in 1977 when he posed the following problem to the readers of Analysis.

This book offers an important study of Aristotle's theory of the sense-organs. It aims to answer two questions central to Aristotle's psychology and biology: why does Aristotle think we have sense-organs, and why does he describe the sense-organs in the way he does? The author looks at all the Aristotelian evidence for the five senses and shows how pervasively Aristotle's accounts of the sense-organs are motivated by his interest in form and function. The book also engages with the celebrated problem (...) of whether perception for Aristotle requires material changes in the perceiver. It argues that, surprisingly to the modern philosopher, nothing in Aristotle's description of the sense-organs requires us to believe in such changes. (shrink)

Professional identity and competent ethical behaviors of nursing students are commonly developed through curricular inclusion of professional nursing values education. Despite the enactment of this approach, nursing students continue to express difficulty in managing ethical conflicts encountered in their practice. This descriptive correlational study explores the relationships between professional nursing values, self-esteem, and ethical decision making among senior baccalaureate nursing students. A convenience sample of 47 senior nursing students from the United States were surveyed for their level of internalized professional (...) nursing values (Revised Professional Nursing Values Scale), level of self-esteem (Rosenberg’s Self-Esteem Scale), and perceived level of confidence in ethical decision making. A significant positive relationship (p < 0.05) was found between nursing students’ professional nursing values and levels of self-esteem. The results of this study can be useful to nursing educators whose efforts are focused on promoting professional identity development and competent ethical behaviors of future nurses. (shrink)

When physical structures resonate in proximity to each other they will under certain circumstances 'sync up' in a shared resonance frequency. This is the phenomenon of spontaneous selforganization. General resonance theory (GRT), a theory of consciousness developed by Hunt and Schooler, suggests that consciousness is a product of various shared resonance frequencies at different physical scales. I suggest a heuristic for calculating the boundaries and resulting capacity for phenomenal consciousness in such resonating structures. Shared resonance results in phase transitions in (...) the speed and bandwidth of information exchange and thus richer and more complex consciousness. This approach is a solution to the 'combination problem' and 'boundary problem' of consciousness. The proposed mathematical heuristic is a practical approach for identifying potential conscious structures and the spatial and temporal boundaries of such structures over time, and also for calculating the capacity for phenomenal consciousness of any putative conscious entity. The slowest-frequency shared resonance -- the 'slowest common denominator'-- is the limiting factor for the spatial extent of any macro-consciousness. Various synchrony indexes are discussed. I describe some limitations of the proposed framework, and how it compares to Tononi's integrated information theory. IIT's constellation- qualia characterization framework is compatible with GRT and may be a useful tool in conjunction with GRT's quantification framework. (shrink)

Wittgenstein’s rule-following argument suggests that linguistic understanding does not consist in knowing interpretations, whereas Kripkenstein’s version suggests that meaning cannot be metaphysically fixed by interpretations. In the present paper, rule-following considerations are used to suggest that certain ontological questions cannot be answered by interpretations. Specifically, if the aim is to specify the ontology of a language, an interpretation cannot answer what object an expression of L denotes, if the interpretations are themselves L-expressions. Briefly, that’s because the ontology of such interpretations (...) would naturally be in question as much as the expressions they interpret. So in order to settle the question of ontology, the interpretations themselves would need to be interpreted, and thus a regress. I conclude that knowing the answer to what ontology underlies L cannot be a matter of knowing interpretations. The paper ends with a quietist conclusion; the slogan is that empirical science is ontology enough, or rather, it is about all the ontology one should expect. (shrink)

The Gouldian argument for evolutionary contingency found in Wonderful Life can be dissected into three premises: palaeontological, macro-evolutionary, and developmental. Discussions of evolutionary contingency have revolved primarily around the developmental. However, a shift in methodological practice and new palaeontological evidence subsequent to the book’s publication appears to threaten the palaeontological premise that asserts high Cambrian disparity, or, roughly, that morphological differences between the Cambrian species were high. This presents a prima facie problem: Did the Cambrian consist of enough anatomical variety (...) to fuel a different outcome upon a replay of the tape of life? I investigate the role that disparity plays in the Gouldian argument for evolutionary contingency and conclude that the reduced disparity view does not undermine the argument, per se. As for the macro-evolutionary premise, Gould never offers any explicit justification for the idea that species sorting was indiscriminate or ‘lottery-like’ (though he certainly gestures at it). Putting aside the exegetical, I consider certain empirical avenues for underwriting the macro-evolutionary premise and argue that the most plausible route is to appeal to the special status of mass extinctions, a move that is not entirely unfamiliar to macro-evolutionists. That is, mass extinctions can be good sources of contingency due to their being ‘chancy’ in at least three respects. In sum, I update the palaeontological and macro-evolutionary premises as to reconstrue the Gouldian argument for evolutionary contingency in its strongest form. (shrink)

Both Plato and Aristotle have something to say about admiration. But in order to know where to look, and in order to appreciate the force of their remarks, we need to sketch a little of the ethical background that they presuppose. I begin, therefore, with ancient Greek ethics in the wider sense, and discuss the treatment of admiration and related attitudes by Homer, Herodotus, and other pre-Platonic sources. Then I turn to the views of Plato, Adam Smith, Aristotle and Cicero. (...) This order of discussion allows us to see why admiration is both morally significant and, in some respects, morally unreliable. (shrink)

Context: The enactive paradigm in the cognitive sciences is establishing itself as a strong and comprehensive alternative to the computationalist mainstream. However, its own particular historical roots have so far been largely ignored in the historical analyses of the cognitive sciences. Problem: In order to properly assess the enactive paradigm’s theoretical foundations in terms of their validity, novelty and potential future directions of development, it is essential for us to know more about the history of ideas that has led to (...) the current state of affairs. Method: The meaning of the disappearance of the field of cybernetics and the rise of second-order cybernetics is analyzed by taking a closer look at the work of representative figures for each of the phases: Rosenblueth, Wiener and Bigelow for the early wave of cybernetics, Ashby for its culmination, and von Foerster for the development of the second-order approach. Results: It is argued that the disintegration of cybernetics eventually resulted in two distinct scientific traditions, one going from symbolic AI to modern cognitive science on the one hand, and the other leading from second-order cybernetics to the current enactive paradigm. Implications: We can now understand that the extent to which the cognitive sciences have neglected their cybernetic parent is precisely the extent to which cybernetics had already carried the tendencies that would later find fuller expression in second-order cybernetics.

Contingency-theorists have gestured to a series of phenomena such as random mutations or rare Armageddon-like events as that which accounts for evolutionary contingency. These phenomena constitute a class, which may be aptly called the ‘sources of contingency’. In this paper, I offer a probabilistic conception of what it is to be a source of contingency and then examine two major candidates: chance variation and genetic drift, both of which have historically been taken to be ‘chancy’ in a number of different (...) senses. However,contrathe gesturing of contingency-theorists, chance variation and genetic drift are not always strong sources of contingency, as they can be non-chancy in at least one sense that opposes evolutionary contingency. The probabilistic conception offered herein allows for sources of contingency to appropriately vary in strength. To this end, I import Shannon’sinformation entropyas a statistical measure for systematically assessing the strength of a source of contingency, which is part and parcel of identifying sources of contingency. In brief, the higher the entropy, the greater the strength. This is also empirically significant because molecular, mutational, and replicative studies often contain sufficient frequency or probability data to allow for entropies to be calculated. In this way, contingency-theorists can evaluate the strength of a source of contingency in real-world cases. Moreover, the probabilistic conception also makes conceptual room for the converse of sources of contingency: ‘sources of directionality’, which ought to be recognised, as they can interact with genuine sources of contingency in undermining evolutionary contingency.

Are there universal structures or stages of experience, so-called contemplative landmarks, that unfold during meditative practice? As commonly described in contemplative manuals or handbooks, there is a transition from a form of meditation where the subject must exert continual effort in order for consciousness to remain focused. As Kenneth Rose has recently shown, these manuals, stemming from the Buddhist, Hindu, and Christian traditions, agree that a transition will take place from effortful meditation into a state where attention is fixed or (...) locked in on the meditation object. This article describes the micro-phenomenology of this phenomenon, sometimes called dhyana or access concentration, from the first-person perspective. This study both confirms and refines the traditional account, engaging with certain difficulties involved in establishing a correspondence between traditional, clear-cut, and sometimes contradictory concepts and actual experiences, which can be hard to conceptualize precisely.

It is a consequence of Quine’s confirmation holism that the logical laws are in principle revisable. Some have worried this is at odds with another dictum in Quine, viz., that any translation which construes speakers as systematically illogical is ipso facto inadequate. In this paper, I try to formulate exactly what the problem is here, and offer a solution to it by (1) disambiguating the term ‘logic,’ and (2) appealing to a Quinean understanding of ‘necessity.’ The result is that the (...) different theses in Quine’s philosophy of logic are to be situated within different contexts of inquiry.

An interpretation is offered of thrasymachus' account of the nature of justice and just action in book I of the 'republic' which is internally consistent throughout on all important points.

The ArgumentRecent archival research has brought about a new understanding of the import of Einstein's puzzling remarks (1916) attributing a physical meaning to general covariance. Debates over the scope and meaning of general covariance still persist, even within physics. But already in 1921 Cassirer identified the significance of general covariance as a novel stage in the development of the criterion of objectivity within physics; an account of this development, and its implications, is the primary task undertaken in his monograph of (...) “epistemological considerations” on the theory of relativity. Cassirer's assessment is correct: general covariance, understood as an injunction against dynamical theories with background elements, is a “limiting heuristic principle” guiding Einstein's fundamental conception of a “complete field theory”; as such, it underlies a “separation principle” built into the conceptual framework of the EPR criticism of quantum mechanics. In conclusion, a further parallel is noted: mutual recognition that the principle of general covariance is but a form of “anthropomorphism.”. (shrink)

It is a particular pleasure to be able to participate in this symposium in honor of Amartya Sen. We agree on a wide range of topics, but I will focus here on an area of relative disagreement. Sen is much more attracted to consequentialism than I am, and the main topic of my paper will be the particular version of consequentialism that he has articulated and the reasons why he is drawn to this view.

Multiple Sclerosis is a debilitating chronic autoimmune disease of the central nervous system that results in lower quality of life. Medication adherence is important for reducing relapse, disease progression, and MS-related symptoms, particularly during the early stages of MS. However, adherence may be impacted by negative emotional states. Therefore, it is important to identify protective factors. Past research suggests that the ability to discriminate between negative emotional states, also known as negative emotion differentiation, may be protective against enactment of maladaptive (...) risk-related behaviors. However, less is known as to how NED may promote adaptive health behaviors such as medication adherence. Utilizing weekly diaries, we investigated whether NED moderates the association between negative affect and medication adherence rates across 58 weeks among patients newly diagnosed with MS. Results revealed that NED significantly moderated the relationship between negative affect and medication adherence. Specifically, greater negative affect was associated with lower adherence only for individuals reporting low NED. However, this link disappeared for those reporting moderate to high NED. Building upon past research, our findings suggest that NED may promote adaptive health behaviors and have important clinical implications for the treatment and management of chronic illness.

Agent-relative consequentialism is thought attractive because it can secure agent-centred constraints while retaining consequentialism's compelling idea—the idea that it is always permissible to bring about the best available outcome. We argue, however, that the commitments of agent-relative consequentialism lead it to run afoul of a plausibility requirement on moral theories. A moral theory must not be such that, in any possible circumstance, were every agent to act impermissibly, each would have more reason to prefer the world thereby actualized over the (...) world that would have been actualized if every agent had instead acted permissibly.

This article attempts to answer certain questions that arise regarding the dialogues as penned by Plato centuries ago. The speaker or the narrator of the text happens to be Socrates, who through various conversations with his apprentices unravels the nuances of the various philosophical dialogues.

[For a planned Festschrift on William Lycan, edited by Mitch Green and Jan Michel.] Lycan (2022) sums up his (2019) _On Evidence in Philosophy_ as a “dolorous” book. This is primarily because the book claims that the field is infected with non-rational socio-psychological forces (fashion, bias, etc.) and that there is a persistent lack of consensus on philosophical questions. In this paper, I primarily rebut Lycan's second reason for dolorousness. For one, if we attend carefully to his text, his metaphilosophical (...) despair seems to die a death of 1000 qualifications. For another, several of the most important qualifications to such pessimism have been omitted. In attending to these, we shall see that philosophy has much to be proud of. I also offer an explanation for why many optimistic signs for philosophical progress tend to escape our notice. (shrink)

This “Legal Briefing” column covers recent legal developments involving patient decision aids. This topic has been the subject of recent articles in JCE. It is included in the 2010 Patient Protection and Affordable Care Act. And it has received significant attention in the biomedical literature, including a new book, a thematic issue of Health Affairs, and a recent article in the New England Journal of Medicine. Moreover, physicians and health systems across the United States are increasingly integrating decision aids into (...) their clinical practice. Both federal and state laws play a significant role in promoting this expanded use. On the other hand, concerns about liability could stymie development and implementation. We categorize legal developments concerning patient decision aids into the following five sections:1. Development of decision aids2. Effectiveness of decision aids3. Federal regulation of decision aids4. State regulation of decision aids5. Legal concerns regarding decision aids. (shrink)

The American Antitrust Institute, a Washington, D.C. think tank, recently completed a study that concludes that competition law and policy plays little if any role in business ethics courses taught in U.S. business schools. To fill this intellectual void, this article makes a case for the development of a business ethics sub-field of antitrust ethics that is synonymous with the ethics of competitive strategy. After reviewing Paine''s Five Principles of Positive Competition and Boatright''s and Hendry''s views on the Moral Manager (...) Model and Moral Market Model, the need for ethical decision-making in a dynamic, innovative environment is explained through a Federal Trade Commission antitrust case involving the Dell Computer Corporation. The author argues that the contributions of Paine, Boatright, and Hendry provide an initial foundation for further research concerning the moral theories, principles, and rules pertaining to antitrust ethics, especially as it pertains to dynamic competition and "fair and competitive" executive behavior.

This paper details an algorithm for a binary, primitive recursive function that apparently computes, for any $i$ and $n$, $f_i\left(i,n\right)$. The algorithm works by exploiting the fact that, in the formal system described, the index assigned to a p.r. function codes the definitional composition of the function. The algorithm exploits such a code to generate a "canonical proof" of $f_i\left(i,n\right)=m$. Since this kind of algorithm is shown impossible by diagonal arguments, the algorithm must be in error. But the error is (...) worth investigating, for it is unclear upon sustained, earnest reflection where it lies. I thus offer this material to readers with a humble request for assistance. (shrink)

The Mental Capacity Act is an impressive piece of legislation that deserves serious ethical attention, but much of the commentary on the Act has focussed on its legal and practical implications rather than the underlying ethical concepts. This paper examines the approach that the Act takes to best interests. The Act does not provide an account of the underlying concept of best interests. Instead it lists factors that must be considered in determining best interests, and the Code of Practice to (...) the Act states that this list is incomplete. This paper argues that this general approach is correct, contrary to some accounts of best interests. The checklist includes items that are unhelpful. Furthermore, neither the Act nor its Code of Practice provides sufficient guidance to carers faced with difficult decisions concerning best interests. This paper suggests ways in which the checklist can be developed and discusses cases that could be used in an updated Code of Practice. (shrink)

This essay considers the ways in which the various contexts – abortion, prenatal diagnosis, fetal research, and the use of fetuses in transplantation – shape the American debate on the moral standing of the fetus. This discussion gives rise to several philosophical debates on the status of the preimplantation embryo, particularly the debate over when the preimplantation embryo becomes individuated. How that question is resolved has critical ethical and policy implications.

If there is such a thing as a genuine property appropriately called "intrinsic value" this property must be such that recognition that something does, or would, possess it, has a necessary tendency to motivate towards sustaining that thing in existence or producing it (if possible). There is just one thing which possesses that property and that is the property of being pleasurable (properly conceived) which, therefore, is the same as intrinsic value. (The same, mutatis mutandis, applies to intrinsic disvalue and (...) painfulness.) Why this seems not to be so is explained. (shrink)
