We investigate computability of a self-similar set on a Euclidean space. A nonempty compact subset of a Euclidean space is called a self-similar set if it equals to the union of the images of itself by some set of contractions. The main result in this paper is that if all of the contractions are computable, then the self-similar set is a recursive compact set. A further result on the case that the self-similar set forms a curve is also discussed.

One conceptual question has been puzzling people for a long time: As the observable universe has been expanding, what has it been expanding into and where did it come from? In this essay I will combine the two questions above to one: What is the Total Universe? I will begin attempt to develop such a description by examining the linguistic human limitations because I believe that this language barrier between our evolved language and a description of the total universe can (...) be surmounted. The basis of this approach is the assumption that a universe would be total if it could be described without logical contradiction in infinities or zero-values. (shrink)

This work investigates the ability of the human visual system to discriminate self-similar Gaussian random textures. The power spectra of such textures are similar to themselves when rescaled by some factor h > 1. As such, these textures provide a natural domain for testing the hypothesis that texture perception is based on a set of spatial-frequency channels characterized by filters of similar shape.

Graham Priest argued that all the paradoxes of set theory and logic fall under one schema; and hence they should be solved by one kind of solution. This reply addresses both claims, and counters that in fact at least one paradox escapes the schema, and also some apparently "safe" theorems fall within it; and even for the range of paradoxes so captured by the schema, the assumption of a common solution is not obvious; each paradox surely depends upon the theory (...) and context in which it arises. Details of Priest's proposed solution are also sought. (shrink)

Frailty is a state of increased vulnerability to poor resolution of homeostasis after a stressor event. Frailty is most frequently assessed in the old using the Clinical Frailty Scale (CSF) which ranks frailty from 1 to 9. This assessment typically takes less than one minute and is not validated in patients with learning difficulties or those under 65 years old. The National Institute for Health and Care Excellence (NICE) developed guidelines that use “frailty” as one of the priority-setting criteria for (...) how scarce, but potentially lifesaving, health care resources should be allocated during the COVID-19 pandemic. Similar guidelines have been developed elsewhere. This paper discusses the ethical implications of such rationing and argues that this is an unproven and ethically problematic form of health care rationing. It specifically discusses: (1) how the frailty ascription becomes a self-fulfilling prophecy, (2) the problematic use of “frailty” in COVID-19 “triage,” (3) the circularity of the link between age and frailty, (4) indirect discrimination because of the use of a seemingly neutral criterion in health care rationing, and (5) the difficult link between comorbidities and frailty. It is found that there was no research into the use of global frailty scores as a criterion for access to acute treatment before January 2020 and so it is concerning how readily frailty scoring has been adopted to ration access to potentially lifesaving treatments. Existing gerontological frailty scoring systems have not been developed for this purpose, and repurposing them creates significant ethical issues. (shrink)

We prove that any speedable computably enumerable set may be split into a disjoint pair of speedable computably enumerable sets. This solves a longstanding question of J.B. Remmel concerning the behavior of computably enumerable sets in Blum's machine independent complexity theory. We specify dynamic requirements and implement a novel way of detecting speedability-by embedding the relevant measurements into the substage structure of the tree construction. Technical difficulties in satisfying the dynamic requirements lead us to implement "local" strategies that only look (...) down the tree. The (obvious) problems with locality are then resolved by placing an isomorphic copy of the entire priority tree below each strategy (yielding a self-similar tree). This part of the construction could be replaced by an application of the Recursion Theorem, but shows how to achieve the same effect with a more direct construction. (shrink)

In this paper, I take up the question of whether the phenomenon of self-deception requires a radical sort of partitioning of the mind, and argue that it does not. Most of those who argue in favor of partitioning accept a model of self-deception according to which the self-deceived person desires to and intentionally sets out to form a certain belief that she knows to be false. Such a model is similar to that of deception of other persons, and for this (...) reason is thought to require that the self-deceiver’s mind be partitioned; one “part” of her knows the truth, while the other “part” is convinced of a false belief. I argue that while both the partitionist model and its main competitor should be rejected, each contains a key insight. On the one hand, anti-partitionist models correctly invoke some sort of desire or motivation on the part of self-deceivers as playing a role in the acquisition of their beliefs. But it is partitionists who identify the right sort of desire, namely, the desire to believe. (shrink)

The notion of an agent and the notion of a self are connected, for agency is one role played by the self. Millgram argues for a disunity thesis of agency on the basis of extreme incommensurability across some major life events. We propose a similar negative thesis about the self, that it is composed of relatively independent threads reflecting the different roles and different mind-sets of the person's life. Our understanding of those threads is based on theories of the narrative (...) construction of the self. Our disunity thesis is that there need be no overarching narrative that unifies those narrative threads. To explain how the threads hang together to produce coherent action, we make these positive claims: control normally switches smoothly and unconsciously between threads as circumstances require, within one thread there is likely to be acknowledgment of other threads, some situations require a temporary blending of threads, and some plans and policies reach across different threads and contribute to some coordination among them. Our account of a self provides an account of agency that has merits in comparison to Millgram's. Our narrative approach allows explanations of actions beyond rational deliberation. (shrink)

Little is known about how to generate plausible new scientific ideas. So it is noteworthy that 12 years of self-experimentation led to the discovery of several surprising cause-effect relationships and suggested a new theory of weight control, an unusually high rate of new ideas. The cause-effect relationships were: (1) Seeing faces in the morning on television decreased mood in the evening (>10 hrs later) and improved mood the next day (>24 hrs later), yet had no detectable effect before that (0–10 (...) hrs later). The effect was strongest if the faces were life-sized and at a conversational distance. Travel across time zones reduced the effect for a few weeks. (2) Standing 8 hours per day reduced early awakening and made sleep more restorative, even though more standing was associated with less sleep. (3) Morning light (1 hr/day) reduced early awakening and made sleep more restorative. (4) Breakfast increased early awakening. (5) Standing and morning light together eliminated colds (upper respiratory tract infections) for more than 5 years. (6) Drinking lots of water, eating low-glycemic-index foods, and eating sushi each caused a modest weight loss. (7) Drinking unflavored fructose water caused a large weight loss that has lasted more than 1 year. While losing weight, hunger was much less than usual. Unflavored sucrose water had a similar effect. The new theory of weight control, which helped discover this effect, assumes that flavors associated with calories raise the body-fat set point: The stronger the association, the greater the increase. Between meals the set point declines. Self-experimentation lasting months or years seems to be a good way to generate plausible new ideas. Key Words: breakfast; circadian; colds; depression; discovery; fructose; innovation; insomnia; light; obesity; sitting; standing; sugar. (shrink)

Phenomenological theories have a long history in undermining the traditional opposition between mind and body. According to them, the material, viz. the corporal can serve as a place for the processes of meaning-formation, i.e., as a condition of possibility for any set of relationships forming a body of meaning. In this paper, this manifests itself through the fact that the basic concepts related to corporeality, e.g., perception, movement etc., are the conditions of possibility for any construction of meaning and consciousness (...) process, as also shown by contemporary neuroscience and communication theory in the case of intelligence and communication. However, this was already known to Aristotle, long before the advent of modern neuroscience, but the stakes were even higher for him: the issue of corporeality is itself problematic in terms of determining its boundaries, as the limits of the Self (viz. my body) merge with those of the world. The situation is similar to the passive and active synthesis of Husserl and also to Heidegger’s twofold openness of the Dasein, conflating the boundaries of the Self and the limits of the world for our human being-there, or consciousness.

Relationships between self-ratings and expectations of an ideal U.S. president, were studied in 43 men drawn from a university setting in the eastern coast of the U.S.A. The men first rated themselves on personality variables, life choices (agentic and communal), peacefulness, spirituality, and morality. Then they were presented with a vignette requesting that they describe an ideal U.S. president on inventories measuring personality variables, life choices, peacefulness, spirituality, and morality. For the rating of the ideal U.S. president, they also were (...) asked to respond to a 20 item questionnaire that was a composite of several factors on organization and leadership, morality, spirituality, and peacefulness. The respondents belonged to one of seven different political persuasions, similar in some ways to different cultures. Self-ratings of the men and expectations of the president were highly correlated for extraversion, openness, trait morality, agentic and communal life choices. However, no significant correlations were found between the self-ratings and expectations of the president for neuroticism, agreeableness, conscientiousness, peacefulness, nor state morality. The men were also presented with vignettes for the ideal physician and ideal automechanic and asked to rate each of them on the inventory items. Overall, the U.S. President was rated as more neurotic and immoral in terms of ingrained ideas of right and wrong, but also as more caring for others, transcendent, seeking goodness and truth, forgiving, cooperative, and most concerned with matters of justice and mercy, and more concerned with both agentic (power-seeking) and communal (community-minded) life choices than were either the ideal physician or ideal automechanic. The ideal physician was rated as highest in extra-version, openness, agreeableness, conscientiousness, and overall peacefulness, and lowest in neuroticism. The ideal automechanic was rated as highest in state or situational immorality, and lowest in both agentic (power-seeking, business-mindedness) and communal (community-mindedness) life choices, and also lowest in caring for others well-being, transcendence, seeking goodness and truth, forgiveness and cooperation, being concerned with justice and mercy, overall expectations, overall spirituality, and overall organization and leadership. In general, the self-ratings were significantly related to ratings/expectations, of the U.S. President, ideal physician, and ideal automechanic. The men seemed to identify more with the automechanic than with the present or physician. (shrink)

This chapter describes the application of reduction concepts in emergence and self organization of complex dynamical system. Condition-dependent laws compress and dynamical equation sets provide implicit compressed representations even when most of that information is not explicitly available without decompression. And, paradoxically, there is still the determined march of fundamental analytical dynamics expanding its compression reach toward a Theory of Everything—even while the more rapidly expanding domain of complex systems dynamics confronts its assumptions and its monolithicity. Nor does science fall (...) apart into a disunified aggregate of particular cases since, with fundamental dynamics as a backbone, complex matching up of models across theoretical and empirical domains then articulates its model-structured skeleton. Discussion provides the delicately entwined dance of emergence and reduction providing constraints on compression that also permit its expansion. However, while the vision is not dead, it is currently substantially more complexly structured through model similarities and differences than that initially envisaged and individuals are left with deep questions about compression unresolved.

While distinguishing between the actions and physical boundaries of self and other (non-self) is usually straightforward there are contexts in which such differentiation is challenging. For example, self–other ambiguity may occur when actions of others are similar or complementary to those of the self. Even in the absence of such situational challenges, individuals experiencing hallucinations have difficulties with this distinction, often experiencing thoughts or actions of self as belonging to other agents. This paper explores the role of ambiguity in self–other (...) differentiation, drawing from developmental, psychodynamic, and neurocognitive perspectives. A key proposal is that engagement in contexts that make distinctions between self and other challenging yet necessary allow reality-testing skills related to agency to develop. Attunement in typical caregiver–infant interactions is framed as a safe but inherently ambiguous environment that provides optimal condition for the infant to develop a coherent self–other sense. Vulnerability to psychosis may be related to limited access to such an environment in early development. However, the perceptual, cognitive, and social skills that contribution to attribution are likely to be malleable following infancy and improve though opportunities for boundary play in similarly ambiguous settings. Using music-making to illustrate, we postulate that engagement in intricate joint-actions that blurs agentic boundaries can contribute to the continued development of an adaptive sense of self and other essential to healthy social functioning. Increased insight into the self–other ambiguity may enhance our understanding of mechanisms underlying “self-disorders” such as schizophrenia and eventually extend the range of social and arts-based therapeutic possibilities.

Instead of the half-century old foundational feud between set theory and category theory, this paper argues that they are theories about two different complementary types of universals. The set-theoretic antinomies forced naïve set theory to be reformulated using some iterative notion of a set so that a set would always have higher type or rank than its members. Then the universal u_{F}={x|F(x)} for a property F() could never be self-predicative in the sense of u_{F}∈u_{F}. But the mathematical theory of categories, (...) dating from the mid-twentieth century, includes a theory of always-self-predicative universals--which can be seen as forming the "other bookend" to the never-self-predicative universals of set theory. The self-predicative universals of category theory show that the problem in the antinomies was not self-predication per se, but negated self-predication. They also provide a model (in the Platonic Heaven of mathematics) for the self-predicative strand of Plato's Theory of Forms as well as for the idea of a "concrete universal" in Hegel and similar ideas of paradigmatic exemplars in ordinary thought.

In lieu of an abstract, here is a brief excerpt of the content:Setting the Scientific Bar for the Genetics of BehaviorEric Turkheimer, PhD (bio) and Sarah Rodock Greer, BA (bio)We are grateful for the opportunity to respond to such a varied and challenging set of commentaries. They range from highly supportive to quite disputatious; we will repay the supportive ones ironically, by discussing them only briefly. That will allow us to expand a bit on the more difficult comments, and of (...) course the thoughtful reply from Dr. Dick.Knox, Allen, and DownesKnox, Allen, and Downes imagine a world in which effective polygenic scores for alcohol use exist and conclude that even then there would be no way to use them ethically. We agree, for the most part, but there are several distinctions to consider. The first is among physical, medical, psychiatric, and normal-range behavioral phenotypes. Effective polygenic scores exist for height, and to a somewhat lesser extent for medical conditions like coronary heart disease. Whether or not it is a good idea to deploy them in embryo selection or clinical medicine, that is already happening.We do not think an R2 of 0.35 polygenic scores for complex behavioral phenotypes will ever exist, for all the reasons we outlined in the original paper. If we allow ourselves to imagine it happening, however, there are two explanatory pathways to follow. The first is the raw R2, and let’s stipulate that with more enormous samples or exome sequencing or whatever, respectable values are eventually achieved. The second involves the causal validity underlying black-box prediction. Scientists are taking the first step down that path (although not in Spit for Science [S4S], see the reply below to Lee and Morris) by investigating direct and indirect effects between and within families and examining the portability of polygenic scores (PGS) across environments and ancestries. The most convincing causal evidence would involve the kind of mechanistic causal biology about which enthusiasts like to speculate, but there is little sign of that.We will grant another possibility. Suppose there was a PGS for alcohol at an R2 of 0.35 that worked between families and within them, in [End Page 455] North America, South Asia, Central America, and West Africa. Animal models confirmed that it is related to specific metabolic pathways involved in alcohol. It was related but not identical to other successful PGS that predict cannabis use and other addictions. Ancient DNA studies find that it is high in human remains that were preserved next to the casks of wine that they apparently loved. Pharmacologists use it to develop effective medications for withdrawal. This hypothetical PGS, mechanistically opaque though it might remain, would exist in what Cronbach and Meehl (1955) called a nomological network. It would have construct validity, similar to a good self-report questionnaire. Like PGS for coronary heart disease, people would want to have access to construct valid PGS, and there would probably be no way to prevent people from obtaining them. We repeat that we do not expect this to happen, and as we discuss in the response to Dick below, hypothetical discussions of future scientific outcomes usually turn out to be unscientific wishcasting. It is like insisting that cities need to develop traffic control systems for flying cars.SadlerSadler is probably correct that the exigencies of grant funding explain much of what we have observed in S4S. It is certainly a more charitable explanation than the alternatives. It is interesting to consider that one of several revolutions that have occurred in the years since S4S was conceived is in the realm of scientific design and reporting. Preregistration of research hypotheses might have prevented many of the more dubious outcomes of S4S. Yet those ideas have never been applied to grant proposals, as far as we know. Grant reviews reward grandiose promises. No one has ever received funding for announcing that they hope to make incremental progress at the margins of a difficult and perhaps intractable problem. There is no mechanism to check on whether the big promises in proposals were ever fulfilled. What does get checked is whether and where investigators have published, often without regard to what the... (shrink)

Interpretations of Nietzsche as a virtue theorist have proliferated in recent years as commentators have sought to read him as a modern eudaimonistic philosopher while also attempting to show what makes his contribution to this tradition valuable and distinctive.1While some commentators still contend that interpreting Nietzsche as a eudaimonist is antithetical to his overtly-stated philosophical aims,2 over the last decade there has been a upsurge of support for such readings, especially from commentators who emphasise what they claim is the pervasive (...) influence of the Hellenistic tradition on his work. Keith Ansell-Pearson has argued that Epicurus was a key influence on Nietzsche’s middle period, for example; whereas Michael Ure has claimed that the Stoic thought of Seneca and Epictetus was also highly influential.3 Nevertheless, even those commentators who agree that Nietzsche can be informatively situated, or is even best situated, within the Hellenistic tradition cannot agree on two seemingly-intractable puzzles which any virtue-theoretical reading must solve in order to give a full account of his moral philosophy. The puzzles can be stated as follows: Puzzle 1: Which character traits does Nietzsche endorse as virtues? Puzzle 2: What is Nietzsche’s ethical ideal? This article offers an exegetical strategy to shed light on both puzzles, especially the first one regarding which character traits Nietzsche endorses as virtues which, as we shall see, is tougher to answer by a straightforward appeal to his texts. To elucidate this puzzle, I will propose that his approving comments regarding excellence-based moral philosophy indicate that his own ethics is also structured in terms of an ethical ideal with a requisite set of virtues which, following his ancient philosophical influences, he views as fundamentally connected. As Julia Annas notes, one the most distinctive ‘assumptions which ancient theories make [is] the relationship of [our] virtues to our final end’,4 and given Nietzsche’s interest in, and apparent endorsement of, ancient eudaimonism – especially compared to his invariably scathing remarks on the modern deontological and utilitarian traditions – we have reason to think that he shares this view.5 What is significant for this article, however, is that Nietzsche’s commitment to a kind of eudaimonism modelled on the ancient world offers a potential way to solve both puzzles. If his virtues and ethical ideal are connected in a similar way to ancient eudaimonistic theories, then understanding his ethical ideal allows us to infer which character traits he endorses as virtues, and vice versa. Although it might be objected that a method tackling both puzzles in tandem would be unworkable if their solutions were contained in each other, in what follows I will show that Nietzsche’s extensive comments on his ethical ideal of ‘becoming what one is’ positions us in a strong position to infer which character traits he prizes most highly. I will call these character traits ‘virtues of self-cultivation’. (shrink)

It has been widely theorized and empirically proven that self-regulated learning (SRL) is related to more desired learning outcomes, e.g., higher performance in transfer tests. Research has shifted to understanding the role of SRL during learning, such as the strategies and learning activities, learners employ and engage in the different SRL phases, which contribute to learning achievement. From a methodological perspective, measuring SRL using think-aloud data has been shown to be more insightful than self-report surveys as it helps better in (...) determining the link between SRL activities and learning achievements. Educational process mining on the basis of think-aloud data enables a deeper understanding and more fine-grained analyses of SRL processes. Although students’ SRL is highly contextualized, there are consistent findings of the link between SRL activities and learning outcomes pointing to some consistency of the processes that support learning. However, past studies have utilized differing approaches which make generalization of findings between studies investigating the unfolding of SRL processes during learning a challenge. In the present study with 29 university students, we measured SRLviaconcurrent think-aloud protocols in a pre-post design using a similar approach from a previous study in an online learning environment during a 45-min learning session, where students learned about three topics and wrote an essay. Results revealed significant learning gain and replication of links between SRL activities and transfer performance, similar to past research. Additionally, temporal structures of successful and less successful students indicated meaningful differences associated with both theoretical assumptions and past research findings. In conclusion, extending prior research by exploring SRL patterns in an online learning setting provides insights to the replicability of previous findings from online learning settings and new findings show that it is important not only to focus on the repertoire of SRL strategies but also on how and when they are used.

In lieu of an abstract, here is a brief excerpt of the content:Self-Predication and the "Third Man" Argument ROGER A. SHINER 1.1. IN COMMPm'mO on the 'Third Man' Argument (TMA), Proclus z produces the following line of thought. He argues that. if the relation of resemblance between Form and particular were symmetrical, the argument in question would be valid; the relation is not, however, symmetrical. Where a Form and particular are both alike, have the quality of likeness, the likeness of (...) that which is derived is not the same as the likeness of that from which it is derived, just because of the former's derivatory nature. Consequently, ~k tt~v ala01]x~ bttotoi3c0at ~re[vot~ (sc. xo~ ~Semv), abx~ 8~ xo6~ot~ oSr~xt, 'the sensible particulars resemble the Forms, but they are not in the same relation of resemblance to the particulars' (ibid., 913.29-30). That is to say, the bare relation of similarity may be symmetrical, but the relation of a similar copy to a similar original is not; the copy is 'a copy of' the original, but the original/s not 'a copy of' the copy. This way of defending the Theory of Forms against the TMA I shall for purposes of identification call the 'Ontological Defence'. It lays stress on the ontological difference between Form and particular in order to avoid the fatal implication that the relation between them is symmetrical. If we use the language of predication, the point is as follows: the TMA is valid, if the Forms have a given term predicated of them severally in exactly the same sense as it is predicated of their respective dependent particulars. This, however, is not the case, for the quality in virtue of which a given term is predicated of a given Form differs in ontological status from the quality in virtue of which that term is predicated of that Form's dependent particulars. Thus we see that underlying the Ontological x I am grateful for helpful comments on an earlier version of this paper to Professor Gilbert Ryle, Professor John F. Malcolm and two anonymous readers for this Journal. Since this paper went to press, the following relevant articles have appeared: G.

[3711 372 HISTORY OF PHILOSOPHY Defence is the following assumption--the fact that the Forms are self-predicating only causes problems for the Theory of Forms, if a given Form F and its corresponding particulars, a set of f things, have 'F' predicated of them univocally, are F in precisely the same sense. My thesis in this paper is that this latter assumption is false, it is, rather, quite sufficient for the Self-Predication Assumption (SPA) to be vicious, if 'F' is predicated of both Form and particular not equivocally. This is not the same as 'univocally', and furthermore it is not possible that Plato could have thought of the predication of a term of both Form and particular as equivocal, the only alternative left to him to escape the TMA. The SPA, therefore, is required for the Theory of Forms to make sense, and leads to an ineradicable defect in that Theory. 1.2. One minor terminological point must be noted before we proceed. There are two versions of the TMA in the Parmenides; the first runs from 131eS-132b2, and the second from 132c11-133a7. The second of these explicitly employs the language of copy-resemblance, 7mpdS~tytm ('paradigm'), 6lxoio)tta ('likeness'), ~tKao0~vat ('resemble') as an explication of ~t~0e~tq ('participation'): the first employs the lan~.,uage of cttx6 ~ xai3xa.., eIvat ('that by which things are...'), which, as Plato has already indicated (Phaedo 100d6-8), is deliberatety noncommittal as to the relation between Forms and particulars.

The model of self-referential truth presented in this paper, named Revision-theoretic supervaluation, aims to incorporate the philosophical insights of Gupta and Belnap’s Revision Theory of Truth into the formal framework of Kripkean fixed-point semantics. In Kripke-style theories the final set of grounded true sentences can be reached from below along a strictly increasing sequence of sets of grounded true sentences: in this sense, each stage of the construction can be viewed as an improvement on the previous ones. I want to (...) do something similar replacing the Kripkean sets of grounded true sentences with revision-theoretic sets of stable true sentences. This can be done by defining a monotone operator through a variant of van Fraassen’s supervaluation scheme which is simply based on ω-length iterations of the Tarskian operator. Clearly, all virtues of Kripke-style theories are preserved, and we can also prove that the resulting set of “grounded” true sentences shares some nice features with the sets of stable true sentences which are provided by the usual ways of formalising revision. What is expected is that a clearer philosophical content could be associated to this way of doing revision; hopefully, a content directly linked with the insights underlying finite revision processes.

Educational institutions need to respond to global competitive problems, and branding has become a method for higher education institutions to differentiate themselves. Thus, this study attempted to investigate predictors of employee brand-based equity. A cross-sectional research design has been used to record the perception of the teachers, and data are collected using a convenience sampling technique. Before administrating the study on large scale, a pilot testing was conducted, and reliability of the scale and their items was ensured. Pilot testing results (...) indicated a satisfactory reliability level, and constructs correlations were in the assumed directions, which allowed to conduct the study on a large scale. A sample size of 400 was set, and questionnaires were distributed among the participants, out of which, 376 were received back, while 351 were left at the end after discarding incomplete responses. The left over and completed questionnaires indicate 88% response rate. Data have been analyzed through the Smart PLS software by applying the structural equation modeling technique. After establishment of the measurement model through reliability and validity, the structural model was used to test study hypotheses. All the study hypotheses were found statistically significant on the basis of t and p statistics. Results indicate that teacher’s emotional intelligence enhances teachers’ self-efficacy, which further improves their brand-based equity. Similarly, emotional intelligence increases teacher’s performance, which also increases their brand-based equity. Limitations and future directions of the study are also reported. (shrink)

This institutional self-study investigated the use of text-matching software to prevent plagiarism by students in a Canadian university that did not have an institutional license for TMS at the time of the study. Assignments from a graduate-level engineering course were analyzed using iThenticate®. During the initial phase of the study, similarity scores from the first student assignments were collected to determine a baseline level of textual similarity. Students were then offered an educational intervention workshop on academic integrity. Another set of (...) similarity scores from consenting participants’ second assignments were then collected, and a statistically significant assignment effect was found between the similarity scores of the two assignments. The results of this study indicate that TMS, when used in conjunction with educational interventions about academic integrity, can be useful to students and educators to prevent and identify academic misconduct. This study adds to the growing body of empirical research about academic integrity in Canadian higher education and, in particular, in engineering fields. (shrink)

The paradoxes of self-reference are genuinely paradoxical. The liar paradox, Russell’s paradox and their cousins pose enormous difficulties to anyone who seeks to give a comprehensive theory of semantics, or of sets, or of any other domain which allows a modicum of self-reference and a modest number of logical principles. One approach to the paradoxes of self-reference takes these paradoxes as motivating a non-classical theory of logical consequence. Similar logical principles are used in each of the paradoxical inferences. If one (...) or other of these problematic inferences are rejected, we may arrive at a consistent (or at least, a coherent) theory. In this paper I will show that such approaches come at a serious cost. The general approach of using the paradoxes to restrict the class of allowable inferences places severe constraints on the domain of possible propositional logics, and on the kind of metatheory that is appropriate in the study of logic itself. Proof-theoretic and model-theoretic analyses of logical consequence make provide different ways for non-classical responses to the paradoxes to be defeated by revenge problems: the redefinition of logical connectives thought to be ruled out on logical grounds. Non-classical solutions are not the “easy way out” of the paradoxes. (shrink)

As the labeling costs in legal artificial intelligence tasks are expensive. Therefore, it becomes a challenge to utilize low cost to train a robust model. In this paper, we propose a LAIAugment approach, which aims to enhance the few-shot learning capability in legal artificial intelligence tasks. Specifically, we first use the self-training approach to label the amount of unlabelled data to enhance the feature learning capability of the model. Moreover, we also search for datasets that are similar to the training (...) set by improving the text similarity function. We conducted experimental analyses for three legal artificial intelligence tasks, including evidence extraction, legal element extraction, and case multi-label prediction, which composed of 3500 judgement documents. The experimental results show that the proposed LAIAugment method has an average F1-score of 72.3% on the three legal AI tasks, which is 1.93% higher than the baseline model. At the same time, it shows a huge improvement in few-shot learning. (shrink)

If is a random sequence, then the sequence is clearly not random; however, seems to be “about half random”. L. Staiger [Kolmogorov complexity and Hausdorff dimension, Inform. and Comput. 103 159–194 and A tight upper bound on Kolmogorov complexity and uniformly optimal prediction, Theory Comput. Syst. 31 215–229] and K. Tadaki [A generalisation of Chaitin’s halting probability Ω and halting self-similar sets, Hokkaido Math. J. 31 219–253] have studied the degree of randomness of sequences or reals by measuring their “degree (...) of compression”. This line of study leads to various definitions of partial randomness. In this paper we explore some relations between these definitions. Among other results we obtain a characterisation of Σ1-dimension in terms of strong Martin-Löf ε-tests , and we show that ε-randomness for ε is different than the classical 1-randomness. (shrink)

Collectively, lawyers probably seek in vain to be sufficiently trusted, even when most individual lawyers appear to do their utmost to behave responsibly. Efforts to address lawyers' behavioural failures remain an important social policy objective and a professional obligation. In this article we argue that it is politically sensible and socially responsible for the legal profession to continue to address its misbehaving members in a more fundamental manner than just the post-facto disciplinary process. We suggest that pre-emptive (pre-offence), ethics self-assessments (...) may limit the later incidence of misbehaviour and assist in rehabilitation programs for disciplined lawyers. We report on an experimental approach to lawyers' discovering more about their innate ethics. We have trialled lawyers' responses to a series of concrete statements about their ethical priorities and developed a statistically valid 'scale' (or set of statements) to allow lawyers in an Australian context to observe and reflect upon, their differing ethical approaches. To date, no such a scale has been developed for lawyers' ethics. The results of this scale development process are sufficiently encouraging to justify further work on similar scales for different cultures and legal traditions, in the interest of producing a tailored, reliable and valid instrument for general pre-emptive use within each local profession. The proposition that awareness improves conscious decision-making is not revolutionary or particularly contentious. While raising lawyers' awareness of how they make choices may only make a modest contribution to enhancing the ethical quality of their professional behaviour, it nevertheless seems plausible that it will raise their awareness and is therefore a worthwhile exercise.

We defend the many-worlds interpretation of quantum mechanics against the objection that it cannot explain why measurement outcomes are predicted by the Born probability rule. We understand quantum probabilities in terms of an observer's self-location probabilities. We formulate a probability postulate for the MWI: the probability of self-location in a world with a given set of outcomes is the absolute square of that world's amplitude. We provide a proof of this postulate, which assumes the quantum formalism and two principles concerning (...) symmetry and locality. We also show how a structurally similar proof of the Born rule is available for collapse theories. We conclude by comparing our account to the recent account offered by Sebens and Carroll. (shrink)

Multi-user online environments involve millions of participants world-wide. In these online communities participants can use their online personas – avatars – to chat, fight, make friends, have sex, kill monsters and even get married. Unfortunately participants can also use their avatars to stalk, kill, sexually assault, steal from and torture each other. Despite attempts to minimise the likelihood of interpersonal virtual harm, programmers cannot remove all possibility of online deviant behaviour. Participants are often greatly distressed when their avatars are harmed (...) by other participants’ malicious actions, yet there is a tendency in the literature on this topic to dismiss such distress as evidence of too great an involvement in and identification with the online character. In this paper I argue that this dismissal of virtual harm is based on a set of false assumptions about the nature of avatar attachment and its relation to genuine moral harm. I argue that we cannot dismiss avatar attachment as morally insignificant without being forced to also dismiss other, more acceptable, forms of attachment such as attachment to possessions, people and cultural objects and communities. Arguments against according moral significance to virtual harm fail because they do not reflect participants’ and programmers’ experiences and expectations of virtual communities and they have the unintended consequence of failing to grant significance to attachments that we take for granted, morally speaking. Avatar attachment is expressive of identity and self-conception and should therefore be accorded the moral significance we give to real-life attachments that play a similar role. (shrink)

Hume maintained that “since all actions and sensations of the mind are known to us by consciousness, they must necessarily appear in every particular what they are, and be what they appear.” Descartes maintained a very similar doctrine, and Locke and Berkeley held at least part of the doctrine. I shall not try to set out precisely what any of these philosophers thought about self-knowledge; I cite them simply as proponents of the general view which I shall be examining in (...) this paper: namely, that each of us has a special epistemic authority about his own mental life. This view is still widely held, particularly in the form of the thesis that one's sincere avowals of current mental states are incorrigible, i.e., such that, necessarily, no one ever has overriding reason to think them false.

Within the class environment, particularly in the language learning setting, stress is considered to be the most common mental condition educators experience in their work, and due to the effect of stress on teachers, burnout similarly occurs because English as a foreign language teachers periodically experience affective trauma while participating and engaging in their careers.

Introduction: Globally, vitamin D deficiency is one of the most common deficiencies, affecting nearly half the world's population. The objective of this survey was to assess and compare the knowledge about vitamin D and the perceived state of health in Emirati and international tourist female students in Dubai, UAE. Methods: This is a cross-sectional study that took place in universities in Dubai, UAE. This survey consisted of 17 multiple choice questions. The first part of the survey assessed levels of supplementation, (...) diet and UV exposure. Another section evaluated the participants’ self-assessed state of health regarding vitamin D testing, symptoms related to vitamin D deficiency and general welbeing. The collected data were statistically analyzed using SPSS statistics for windows version 26.0 (SPSS Inc., Chicago, IL). Statistical significance was set at P<0.05. Results: 105 respondents were Emiratis and 65 were international students. The average age was 21, with an average BMI 23.3. Almost one-third of each group reported using Vitamin D supplements once weekly. The majority of both groups reported rarely getting tanned. Almost all participants reported regular consumption of Vitamin-D rich foods. In both groups, more than half reported consuming milk and cheese regularly and up to one-third reported consuming fish in a regular manner. Although more than half of the students rated their health as good; more than two-thirds reported experiencing muscle pain; only half reported having their blood Vitamin D levels measured once; half reported experiencing problems with concentration and more than three-quarters reported experiencing bad mood in the past month. The prevalence of these symptoms was almost similar across different categories of vitamin D supplementation, tanning habits, dietary intake, or nationality. No statistically significant differences were noted between the 2 groups. Conclusion: more Emirati students were aware of the association between vitamin D and osteoporosis than International tourist students (40% vs. 21.9%, respectively; p<0.05). On the other hand, both groups had lower knowledge about the relationship between vitamin D deficiency and depression, Rheumatoid Arthritis and Hypertension, and the optimal vitamin D level; however, no statistically significant differences were noted regarding this knowledge of Emiratis and international students.

Success in online and blended courses requires engaging in self-regulated learning (SRL), especially for challenging STEM disciplines, such as physics. This involves students planning how they will navigate course assignments and activities, setting goals for completion, monitoring their progress and content understanding, and reflecting on how they completed each assignment. Based on Winne & Hadwin’s COPES model, SRL is a series of events that temporally unfold during learning, impacted by changing internal and external factors, such as goal orientation and content (...) difficulty. Thus, as goal orientation and content difficulty change throughout a course, so might students’ use of SRL processes. This paper studies how students’ SRL behavior and achievement goal orientation change over time in a large (N = 250) college introductory level physics course taught online. Students’ achievement goal orientation was measured by repeated administration of the achievement goals questionnaire-revised (AGQ-R). Students’ SRL behavior was measured by analyzing their clickstream event traces interacting with online learning modulesviaa combination of trace clustering and process mining. Event traces were first divided into groups similar in nature using agglomerative clustering, with similarity between traces determined based on a set of derived characteristics most reflective of students’ SRL processes. We then generated causal nets for each cluster of tracesviaprocess mining and interpreted the underlying behavior and strategy of each causal net according to the COPES SRL framework. We then measured the frequency at which students adopted each causal net and assessed whether the adoption of different causal nets was associated with responses to the AGQ-R. By repeating the analysis for three sets of online learning modules assigned at the beginning, middle, and end of the semester, we examined how the frequency of each causal net changed over time, and how the change correlated with changes to the AGQ-R responses. Results have implications for measuring the temporal nature of SRL during online learning, as well as the factors impacting the use of SRL processes in an online physics course. Results also provide guidance for developing online instructional materials that foster effective SRL for students with different motivational profiles. (shrink)

My aim in this note is to shed light on ways of interpreting Kant’s Formula of Universal Law (FUL), by looking at relevant similarities and differences between Pauline Kleingeld and Mark Timmons. I identify both their readings as a formal interpretation of Kant’s FUL, in contrast to the substantive interpretations that favor a robust conception of rational agency as a necessary requirement for moral deliberation. I highlight the benefits that arise from Kleingled’s interpretation in showing the immediacy involved in the (...) volitional self-contradiction when universalizing a maxim. Alongside Timmons, I address a question as to whether Kleingeld’s interpretation is completely free from at least a minimal set of assumptions about practical deliberation more broadly, that seem to play a role in generating the volitational self-contradiction she is defending. I close by raising some skeptical worries about the capacity of this kind of contradiction to translate into a moral judgment triggering action. (shrink)

Bainbridge’s well known “Ironies of Automation” Analysis, design and evaluation of man–machine systems. Elsevier, Amsterdam, pp 129–135, 1983. https://doi.org/10.1016/B978-0-08-029348-6.50026-9) laid out a set of fundamental criticisms surrounding the promises of automation that, even 30 years later, remain both relevant and, in many cases, intractable. Similarly, a set of ironies in technologies for sensor driven self-quantification is laid out here, spanning from instrumental problems in human factors design to much broader social problems. As with automation, these ironies stand in the way (...) of many of the promised benefits of these wearable technologies. It is argued here that without addressing these ironies now, the promises of wearables may not come to fruition, and instead users may experience outcomes that are opposite to those which the designers seek to afford, or, at the very least, those which consumers believe they are being offered. This paper describes four key ironies of sensor driven self-quantification: know more, know better versus no more, no better; greater self-control versus greater social control; well-being versus never being well enough; more choice versus erosion of choice.

The phenomenon whereby severely disabled persons self-report a higher than expected level of subjective well-being is called the “disability paradox.” One explanation for the paradox among brain injury survivors is “response shift,” an adjustment of one’s values, expectations, and perspective in the aftermath of a life-altering, disabling injury. The high level of subjective well-being appears paradoxical when viewed from the perspective of the non-disabled, who presume that those with severe disabilities experience a quality of life so poor that it might (...) make their lives not worth living. This presumption has profound consequences, for it may inform end-of-life choices made in advance directives, or influence decisions made by surrogates on behalf of persons who are unable to direct their own medical treatment. -/- Peterson et al propose a cautious, well-considered plan to use fMRI-based brain-computer interfaces to assess the decision making capacity of covertly aware, behaviorally non-responsive individuals who retain high levels of preserved cognition. Their plan, if it succeeds, could eventually restore autonomy and empower some severely disabled persons, allowing them to participate in clinical decision making. Peterson et al discuss possible in-principle objections to their proposal, among them the “argument from psychological health,” and the “changing sets of values” objection. These objections both presume that deviations from a pre-injury norm could indicate diminished decision making capacity. This presumption threatens the autonomy of the patient who is capable of making decisions, but whose post-injury decisions appear to diverge from pre-injury preferences or values. In light of the potential for response shift, and the disability paradox, it should not be inferred that changes in values or preferences are unreflective of the true current preferences of a brain-injured person, nor are they conclusive evidence of diminished capacity. Presuming diminished capacity on the basis of unexpected or unconventional preferences has, in the past, been used to disempower patients whose autonomy and capacity would not have been doubted had they made choices that accorded with the expectations or values of others. We must be cautious, and vigilant, to prevent similarly diminishing the autonomy of covertly aware, behaviorally non-responsive individuals on the basis of empirically and ethically questionable inferences about their decision making capacity.

At first glance, Schopenhauer’s account of human freedom looks strikingly similar to Schelling’s account of formal freedom in the Freiheitsschrift. Despite the clear similarities, I argue that there is a decisive difference between the two accounts—a difference that has to do with the ultimate grounding of freedom. For Schelling, the intelligible deed is a radical self-grounding of the eternal essence of the human being. For Schopenhauer, the eternal essence of the human being is groundless. Moreover, I argue that this difference (...) has decisive consequences for two sets of issues. On the one hand, Schelling’s concept of self-grounding allows him to preserve the universal application of the principle of ground. On the other hand, self-grounding is the only way that human beings can be responsible for who they are. Schelling thus anticipates a key insight of Galen Strawson: ultimate moral responsibility is only possible for a causa sui. (shrink)

We usually withhold attributions of moral responsibility when a person acts on preferences that are induced without her consent by other people by means of conditioning, post-hypnotic suggestion, neurological fiddling and similar techniques. However, this is not generally the case when a person induces preferences in herself by the process of character building. However, the distinction between non-responsibility and responsibility for preferences does not map neatly onto the distinction between psychological induction by other and by self. Sometimes responsibility-grounding freedom of (...) action and autonomy of will re compromised when a person induces preferences in herself by adaptive preference-formation, the mechanism that sets up the cry of “sour grapes.” They can also be compromised when a person intentionally undertakes a strategy of self-abnegating resignation to oppressive necessity. It remains unclear, nonetheless, how the unfreedom and heteronomy of preferences calibrated to the merely feasible contrasts with the freedom and autonomy of planned preferences-changes guided by the person’s own values in projects of character building.

This paper examines an example of learning with artifacts using the commonplace materials of string and knots. Emphases include research into learning processes as well as construction of objects to assist learning. The inquiry concerns the development of mathematical thinking, topology in particular. The research methodology combines participant observation and clinical interview within a constructionist framework. The study was set in a self-styled, self-constructed environment that consisted of knots and a social substrate encouraging lively exchanges of ideas about them. Comparisons (...) of certain knots helped to elicit conceptions of the fundamental topological relationships of neighborhood, continuity, and boundaries. The paper includes comments on the suitability of specific artifacts for specific kinds of thinking and learning, and emphasizes the importance for software design of considering different learning styles.

Reports of research fraud have raised concerns about research integrity similar to concerns raised about financial accounting fraud. We propose a departure from self-regulation in that researchers adopt the financial accounting approach in establishing trust through an external validation process, in addition to the reporting entities and the regulatory agencies. The general conceptual framework for reviewing financial reports, utilizes external auditors who are certified and objective in using established standards to provide an opinion on the financial reports. These standards have (...) become both broader in scope and increasingly specific as to what information is reported and the methodologies to be employed. We believe that the financial reporting overhaul encompassed in the US Sarbanes–Oxley Act of 2002, which aims at preventing accounting fraud, can be applied to scientific research in 4 ways. First, Sarbanes–Oxley requires corporations to have a complete set of internal accounting controls. Research organizations should use appropriate sampling techniques and audit research projects for conformity with the initial research protocols. Second, corporations are required to have the chief financial officer certify the accuracy of their financial statements. In a similar way, each research organization should have their vice-president of research (or equivalent) certify the research integrity of their research activities. In contrast, the primary responsibility of the existing Research Integrity Officers is to handle allegations of research misconduct, an after-the-fact activity. Third, generally accepted auditing standards specify the appropriate procedures for external review of a corporation’s financial statements. For similar reasons, the research review process would also require corresponding external auditing standards. Finally, these new requirements would be implemented in stages, with the largest 14 research organizations that receive 25% of the total National Institutes of Health funding, adopting these research oversight enhancements first.

Economic models are founded in the idea of taking individuals' preferences as both known and given. This article explores the evolution of personal preferences, within a context of both entrepreneurial discovery and Objectivist philosophy. It begins by formalizing Ayn Rand's theory of Objectivism applied to human values, and continues by modeling preference changes similar to Schumpeter's theory of creative destruction—a process of self-discovery. Next the role of societal factors is examined in forming shared preference sets. Finally, the article describes how (...) the strength of human preferences is used to narrow choice sets in the presence of greater consumption options. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.4 (2003) 361-367 [Access article in PDF] Psychopathology and Two Kinds of Narrative Account of the Self Tim Thornton Keywords self, narrative, reductionism, embodiment, Dennett, Strawson, McDowell The self plays an important role in psycho pathology. Conditions such as dementia raise the question of how much loss of memory and awareness there can be before there is, if ever, also a loss of the self. (...) Syndromes such as Dissociative Identity Disorder (DID) or Multiple Personality Disorder (MPD) raise the possibility of a fragmentation of one self into a number of selves. Depersonalization disorder suggests a kind of diminution both of the sense of self and the reality of the world. Symptoms such as thought insertion suggest a different kind of fragmentation of the coherence of thought within a self.At the same time there is something prima facie paradoxical about the very idea of the fragmentation or loss of self. It seems to be one thing for a self to suffer loss, quite another to think of the self as being lost. Although the experiences or beliefs had or entertained by a self might be disordered or chaotic, how can a self be anything other than whole and seem real and whole to itself?The narrative approach to the self looks like a tool purpose built to shed light on some aspects of psychopathology. The papers in this issue have examined its application to four revealing case histories and questioned its effectiveness in accounting for features of psychopathology. But in this short note I wish to stand back from the particular cases discussed in previous papers and to shed light on the general approach by setting out two contrasting versions of it. Crudely put, the first forges a connection between the concepts of self and personality; the second between the concepts of self and person. I will use the contrast between these two to draw some general lessons for the philosophy of psychopathology. Dennett's Austere Narrative Account I will start with Dennett's influential version of a narrative account of the self. His central idea is that the very idea of a self should be understood as dependent on a particular kind of interpretative strategy. Roughly, this contrasts with the idea that it is a more basic datum calling out for notice prior to adopting a specific theoretical perspective.Dennett suggests an analogy with centers of gravity both to outline the consequences of this view for the reality of selves, and the connection between the self and the interpretative strategy involved. [End Page 361] A center of gravity is just an abstractum. It's just a fictional object. But when I say it's a fictional object, I do not mean to disparage it; it's a wonderful fictional object, and it has a perfectly legitimate place within serious, sober, echt physical science. (Dennett 1992) The concept of a center of gravity is deployed within a branch of physics to describe and predict the behavior of physical systems acting under physical forces. It is the theoretical context that determines the nature of centers of gravity; at the same time, they contribute to that broader context. Dennett stresses that they are abstract or calculation-bound theoretical objects to contrast with objects that are also theoretically posited but causally interactive, such as microphysical particles (Dennett 1987, 53).Dennett has also used the analogy with abstracta to account for mental states such as beliefs, desires, and other propositional attitudes, which he suggests are ascribed using a particular interpretative strategy: the "Intentional Stance" (Dennett 1987, 13-42). The suggestion is that by showing the necessity of adopting that stance to make sense of human behavior he can defend a form of objectivity about mental states even while rejecting the industrial-strength realism that requires identifying mental states with physical, and thus causally interactive, internal states.Selves are given similar treatment. Like centers of gravity or mental states, they are theoretical, even fictional, entities articulated within an interpretative theoretical stance: A self is also an abstract object, a theorist's fiction...

For Dōgen, the Buddhist doctrine of “no self” ultimately presents the self as contextualized. The self is for him not an independent entity, but is intricately related to its environment, determined through the many beings around it. In a quite different philosophical setting, Spinoza developed similar ideas. While Dōgen challenged the specifics of a tradition that explicitly argues against the idea of an absolute self, Spinoza faced a more radical challenge: questioning an absolute, unchanging, and free self that the Western (...) tradition has mostly taken for granted. After an analysis of the ideas of the two thinkers, the essay presents some important implications for contemporary times. Our domination of the earth and one another is arguably rooted in the individualism Dōgen and Spinoza seek to overcome. The insight that we are contextualized is a first step toward re-determining ourselves as placed within a larger whole. (shrink)

The South African government’s COVID-19 pandemic risk mitigation strategies significantly limited social contact, which necessitated a novel approach to existing face-to-face career guidance practices. The Grade 9 Career Guidance Project, originally developed as a group-based career development intervention, required radical adaptation into a self-directed, manualized format to offer career guidance to Grade 9 learners from low-income communities amid a global pandemic. The adaptation and continuation of the project was deemed essential as secondary school learners in low-income communities have limited career (...) guidance support. Furthermore, a close collaboration with the teachers at eight resource-constrained South African secondary schools was vital for successful implementation. To assess the success of the adaptation to a self-directed format, a mixed-methods design was employed, and Life Orientation teachers’ evaluative feedback was solicited. Favorable quantitative results were obtained; majority of teachers agreed that learners enjoyed the booklet and that it was deemed an adequate substitute to the previous contact-based format of the Career Guidance Project. This was also confirmed by the qualitative findings revealing teachers’ satisfaction with the booklet’s content, specifically that the booklet is complementary to the Life Orientation curriculum. Qualitative findings identified specific contextual barriers that contributed to some learners struggling to use the booklet optimally. The results suggest that it is feasible and acceptable to implement a self-directed career guidance intervention among secondary school learners amid a global pandemic. Teachers recommended ways to integrate the booklet, resources, and contact sessions as a preferred way forward. These findings have important implications for similar resource-constrained settings that may not have readily access to in-person career guidance and counseling human development. (shrink)

This is a text for a one or two semester course on axiomatic set theory; the goal is to introduce and develop one system of set theory in a complete and thorough way, presupposing only the elusive "mathematical maturity" of the reader. There are nine chapters which begin with a development of propositional and predicate logic oriented toward set theory and develop the Zermelo-Fraenkel system in exceptional detail. The book starts slowly, the first 120 pages being devoted to logical preliminaries (...) and the introduction of axioms; it gathers speed, however, and the remaining chapters include treatment of the algebra of classes, relations and functions, order of various sorts and Zorn's lemma, real numbers and equivalence classes, the equipollence of sets, similarity as a relation of sets, the ordinal numbers and their arithmetic, the cardinal numbers and their arithmetic. These later chapters are extremely detailed and comprehensive, presenting a wealth of material. There are numerous exercises, many quite difficult, at the end of each chapter, along with a summary of that chapter's content. Because of the single-mindedness of the book, there is little reference to other systems of set theory, but this is not a drawback at all. The presentation is orthodox, but not dull; careful, but not generally pedantic or repetitive. This makes it a good text for self-study.—P. J. M. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Making a New Man: Ciceronian Self-Fashioning in the Rhetorical WorksAndrew M. RiggsbyJohn Dugan. Making a New Man: Ciceronian Self-Fashioning in the Rhetorical Works. Oxford: Oxford University Press, 2005. x + 388 pp. Cloth, $120.The title somewhat undersells this book in two respects. First, in addition to treating several of the rhetorica (De Oratore, Brutus, Orator), it also offers readings of two actual orations (Pro Archia and In Pisonem). (...) Second, and more importantly, self-fashioning in the narrow sense is only half of the project Dugan analyzes. As interested as Cicero was in offering versions of himself to a variety of audiences, he seems to have been at least as interested in fashioning an audience that would evaluate those versions properly (that is, positively). The theatrical character some have noted in much of Roman culture might lead one not to be surprised to find late Republican interest in self-fashioning; and, as Dugan points out, a "new" man such as Cicero would have been particularly self-conscious about the matter. One might even have expected that attempts to change the rules on the fly would be fair game (cf. Pliny Ep. 4.17.3, 6.17.4, 7.4.10). Still, the scale of Cicero's enterprise seems to have no classical parallel and was badly in need of description and analysis. This is the work carried out effectively by Dugan's book. The Cicero being fashioned is in part the togate general and hero of the Catilinarian affair. He is also, however, the cultural producer who tests cultural limits and standards of acceptability and is eventually displaced by his own product.The first chapter argues that Pro Archia adopts an essentially epideictic form to exploit, on the one hand, the ludic associations of that genre and, on the other, its proximity to the aristocratic laudatio funebris. The former licenses Cicero's valuation of literary polishing (roughly, ornatus), explicitly in poetry, but also in history and oratory. The latter co-opts a highly traditional mode of fashioning for a new man who might not have literal access to it. The speech is both an argument for a certain set of values and a demonstration of Cicero's possession of the same: the value of cultural production to the community, the [End Page 473] value of formal polish and aestheticization to that production, the role of texts in processes of exchange, personal auctoritas as the ultimate guarantor of value, and semiotic transparency. This speech and its hoped-for responses would be able to canonize Cicero's version of the Catilinarian conspiracy, a version in which he was the hero. In Pisonem attempts to canonize a vice-ridden Piso by similar means and also sets him in a world where the same values (especially transparency) break down.The second chapter reads De Oratore as a defense of a novel, Ciceronian construct of the ideal orator as in fact traditional. The key to the new aesthetic (beyond its being an aesthetic in sometimes moralizing terms) is "controlled transgression," that is, a tolerance for the metaphorical, the theatrical, the humorous, and in general the potentially indecorous and effeminate. This is made tolerable by a variety of strategies. The overt arguments of the text constantly police the boundaries of decorum (even if they protest too much). The whole is projected back onto ancestors who are automatically respectable and from whom Cicero personally can construct an intellectual genealogy. (Here again we have potential contact with the laudatio funebris.) At the same time, parts of the reputations of some of those maiores are cleaned up to suppress potential controversy. The dialogue form displaces responsibility for any particular claim of characters in the text, even though Cicero does in places stress his own authorship of the whole. Not only are Cicero's would-be weaknesses (such as his perhaps over-ready wit) justified, but he also assumes the role of the regulator. Heavy use of bodily metaphors and refusal of the conventional form/content distinction serve to naturalize Cicero's preference for risking effeminacy for the sake of ornatus.Brutus, the topic of chapter 3, gives a "history" of oratory with a point...

This article analyses the paternalistic justification of the world’s first mandatory tobacco plain packaging policy, which came into force in Australia in 2012. The policy is setting international precedence, with a range of developed and developing countries planning and implementing similar policies. Understanding the paternalistic dimension of the policy is therefore of imminent international importance. The policy meets important ethical benchmarks such as respect for citizens’ self-interests and protection of others against harm. However, plain packaging faces a number of ethical (...) challenges: the policy is a controversial type of paternalism; it runs partially against the harm principle; and it fails to meet key operational criteria.

It has been well documented that children perceive robots as social, mental, and moral others. Studies on child-robot interaction may encourage this perception of robots, first, by using a Wizard of Oz set-up and, second, by having robots engage in self-description. However, much remains unknown about the effects of transparent teleoperation and self-description on children’s perception of, and relationship formation with a robot. To address this research gap initially, we conducted an experimental study with a 2 × 2 between-subject design (...) in which 168 children aged 7–10 interacted with a Nao robot once. Transparency about the teleoperation procedure decreased children’s perceptions of the robot’s autonomy and anthropomorphism. Self-description reduced the degree to which children perceived the robot as being similar to themselves. Transparent teleoperation and self-description affected neither children’s perceptions of the robot’s animacy and social presence nor their closeness to and trust in the robot. (shrink)

The best way to protect information is never to release it. Yet even the earliest definition of security recognizes availability as a necessary quality. In this work, we seek to quantify the value of information disclosure for web resource evaluation and discovery. Communal evaluation tools help users share ratings on websites, music, and other online resources. This approach assumes that experiences are self-similar, so that a site one person visits is likely to have been evaluated and thus visited by others. (...) Collaborative search tools aim for discovery as opposed to evaluation. Therefore, they assume participants in a collaborative network have large sets of non-overlapping sites so that an increase in network size corresponds to an increase in web coverage. We quantify the value of information sharing for these closely related but sometimes distinct functions. In this paper, we analyzed a dataset that includes eight weeks of browsing history of 1084 college students that live in the same dormitory. Our experiments showed that for discovery, more sharing monotonically improves results; for evaluation, however, there are decreasing marginal returns for each participant added to the network. The subject population was selected for its homogeneity in order to mimic a collaborative network. (shrink)

Though they worked in very different disciplines, Max Weber and Thomas Mann were engaged from early in their careers in a remarkably similar enterprise converging on questions of personal identity and national self-understanding, and built upon conceptions drawn from a common intellectual and national heritage. Harvey Goldman's ambitious new book is about a part of that enterprise, the foundation of their understanding of the relation of self and work as set out in Weber's essays on religion and Mann's pre-World War (...) I writings. Weber and Mann sought to revitalize a set of ideas of character and action—calling and personality—to guide their own lives and intellectual creation, as well as politics and the life of the nation. In their hands these ideas also became explanatory tools for understanding the crisis of their class and of Germany. By organizing the interpretation of Weber and Mann around the conceptual nexus of calling and personality, the author reveals a number of issues and problems that have been overlooked, providing an altogether new approach to Weber's famous explanation of the capitalist spirit and recovering a vital modern debate around the idea and meaning of the person. In the convergence of so many themes in their writings, Weber and Mann exemplify the self-understanding of their age and cast a special light on problems of self, identity, and social life. This work contains fascinating material for students of intellectual history and modern political theory. Anyone concerned generally with twentieth-century European history, politics, philosophy, and literature will welcome this rich, vigorously written book. (shrink)
