Guaspari (J Symb Logic 48:777–789, 1983) conjectured that a modal formula is it essentially Σ1 (i.e., it is Σ1 under any arithmetical interpretation), if and only if it is provably equivalent to a disjunction of formulas of the form ${\square{B}}$ . This conjecture was proved first by A. Visser. Then, in (de Jongh and Pianigiani, Logic at Work: In Memory of Helena Rasiowa, Springer-Physica Verlag, Heidelberg-New York, pp. 246–255, 1999), the authors characterized essentially Σ1 formulas of languages including witness (...) comparisons using the interpretability logic ILM. In this note we give a similar characterization for formulas with a binary operator interpreted as interpretability in a finitely axiomatizable extension of IΔ 0 + Supexp and we address a similar problem for IΔ 0 + Exp.

This paper is part of a project that is based on the notion of a dialectical system, introduced by Magari as a way of capturing trial and error mathematics. In Amidei et al. (2016, Rev. Symb. Logic, 9, 1–26) and Amidei et al. (2016, Rev. Symb. Logic, 9, 299–324), we investigated the expressive and computational power of dialectical systems, and we compared them to a new class of systems, that of quasi-dialectical systems, that enrich Magari’s systems with a natural mechanism (...) of revision. In the present paper we consider a third class of systems, that of p-dialectical systems, that naturally combine features coming from the two other cases. We prove several results about p-dialectical systems and the sets that they represent. Then we focus on the completions of first-order theories. In doing so, we consider systems with connectives, i.e. systems that encode the rules of classical logic. We show that any consistent system with connectives represents the completion of a given theory. We prove that dialectical and q-dialectical systems coincide with respect to the completions that they can represent. Yet, p-dialectical systems are more powerful; we exhibit a p-dialectical system representing a completion of Peano Arithmetic that is neither dialectical nor q-dialectical. (shrink)

This book explores C.G. Jung's complex relationship with Friedrich Nietzsche through the lens of the so-called 'visionary' literary tradition. The book connects Jung's experience of the posthumously published Liber Novus with his own understanding of Nietzsche's Zarathustra, and formulates the hypothesis of Jung considering Zarathustra as Nietzsche's Liber Novus –– both works being regarded by Jung as 'visionary' experiences. After exploring some 'visionary' authors often compared by Jung to Nietzsche, the book focuses upon Nietzsche and Jung exclusively. It analyses stylistic (...) similarities, as well as explicit references to Nietzsche and Zarathustra in Liber Novus, drawing on Jung's annotations in his own copy of Zarathustra. The book then uses Liber Novus as a prism to contextualize and understand Jung's five-year seminar on Zarathustra: all the nuances of Jung's interpretation of Zarathustra can be fully explained, only when compared with Liber Novus and its symbology. One of the main topics of the book concerns the figure of 'Christ' and Nietzsche's and Jung's understandings of the 'death of God.'. (shrink)

This article is a first assessment of the Italian Code of deontology for nurses (revised in 1999) on the basis of data collected from focus groups with nurses taking part in the Ethical Codes in Nursing (ECN) project. We illustrate the professional context in which the Code was introduced and explain why the 1999 revision was necessary in the light of changes affecting the Italian nursing profession. The most remarkable findings concern professional autonomy and responsibility, and how the Code is (...) thought of as a set of guidelines for nursing practice. We discuss these issues, underlining that the 1999 Code represents a valuable instrument for ethical reflection and examination, a stimulus for putting the moral sense of the nursing profession into action, and that it represents a new era for professional nursing practice in Italy. The results of the analysis also deserve further qualitative study and future consideration. (shrink)

There is a speed-accuracy trade-off in perception. The ability to quickly extract sensory information is critical for survival, while extended processing can improve our accuracy. It has been suggested that emotions can change our style of processing, but their influence on processing speed is not yet clear. In three experiments, combining online and laboratory studies with different emotion induction procedures, we investigated the influence of both affective states, manipulated with music, and individual traits in sensory-processing sensitivity on the ability to (...) rapidly segregate two visual flashes. Across studies, the musical manipulations pushed participants towards either rapid or slow processing. Individual variations in sensory-processing sensitivity modulated these effects. Our findings demonstrate that affective states, influenced by music, can shift the balance between fast and slow visual processing, altering our perceptual experience. These results also emphasise the interaction of individual traits in sensory processing and affective states. (shrink)

In the Phenomenology of Perception, Merleau-Ponty dedicates many pages to the analysis of pathological cases, which seem to be assessed as merely negative phenomena that reinforce an extrinsic opposition with normal ones. This paper aims to clarify that Merleau-Ponty in effect challenges the able–disabled dichotomy by articulating an intentional analysis based on the perspective of being-in-the-world and proposing a differential understanding of embodiment. Such an analysis demonstrates that ability and disability exist as material and situational events and, simultaneously, form an (...) existential continuum—one that rejects the identification of disability with a disruption (ontological claim) or a degradation (normative claim).

The image of the Roman woman, which has survived to this day and imposed itself almost as the only possibility for the ancient scholarship, is the domiseda: the housewife, mother, and spinner. In addition to the investigations of this traditional depiction, which steered the research on Roman women, the issues of our time and the advances in scientific research constantly bring us new perspectives, approaches, and problems around this object of study. This inevitably motivates us to question the role of (...) women in the business and finance world in Ancient Rome. Is it possible to write an economic and financial history of Roman women? What are the limits of this endeavor? This article addresses the insertion of women in the business and finance world, as well as some of the multiple possibilities of writing the History of Women from the Economic and Social History viewpoint. The time frame is restricted to the end of the Republic and the imperial period. This article is therefore divided into three parts: first, an introduction to the discussion of the situation of women in the domus; secondly, methodological assumptions to the study of women and their placement in economic and financial life; and, finally, some examples ofwomen from three different social groups who appear involved in credit relations in the documentation.

This article pursues the goal of articulating a pedagogical paradigm of philosophy as a way of life that can effectively re-invigorate the teaching of philosophy in today’s academic world. This re-invigoration should take direct inspiration from Hadot’s hermeneutical framework of how to live philosophically, while still recognizing the intrinsic limitations that his model presents when applied to the modern educational practices of academia. In particular, we maintain that a literal application of Hadot’s model would require we turn the teaching of (...) philosophy as a way of life into a systemic affair that demands from students a full commitment to particular schools of thought. Conversely, we argue for a pedagogical paradigm of philosophy as a way of life (“PWOL-as-Situated-Pedagogy”) that enacts a triple balancing between theory and practice, progress and assessment, and depth and breadth. In this way, the problem of self-cultivation is tackled by engaging students with a broader consideration of philosophies and spiritual exercises. (shrink)

When information grows abundant, attention becomes a scarce resource. As a result, agents must plan wisely how to allocate their attention in order to achieve epistemic efficiency. Here, we present a framework for multi-agent epistemic planning with attention, based on Dynamic Epistemic Logic. We identify the framework as a fragment of standard DEL, and consider its plan existence problem. While it is undecidable in the general case, we show that when attention is required for learning, all instances of the problem (...) are decidable. (shrink)

L’ouvrage de F. Stella est une enquête de grande envergure sur la notion d’« intellect » entre la Grèce archaïque et la période classique. Encore hésite-t-on à traduire ainsi le vocabulaire du νόος, car cela reviendrait d’emblée à le lester d’une signification déterminée : celle de l’acte cognitif par excellence, où culmine le geste philosophique d’abstraction. Or le projet de F. Stella est précisément de démontrer que cette signification est le produit d’une histoire : le sens qui se constit...

There is growing public interest in developing biomedical technologies capable of extending the human lifespan. This chapter discusses the desirability of a substantial life extension with regard to its implications for personal identity over time. The possibility of significant lifespan extension involves two different personal‐identity questions. First, it raises the question of whether one is identifiable as the very same person throughout a lifetime; secondly, it challenges our self‐conception. The chapter describes the way in which personal identity as “sameness” might (...) be affected by the prospect of substantial life extension. It then focuses on the significance of the conception of personal identity as “selfhood” for radically extended lifespans. Finally, the chapter argues that a substantial life extension raises important concerns about the continuity of one's identity over time and is not straightforwardly desirable for the individual.

The hypothesis that foreseeable developments in interventions directed to forestall and to treat the disabilities of aging might result in the extension of the human lifespan may be further supported by the “evolutionary theory of aging.” Besides caloric restriction, several hormone supply or replacement strategies are considered to contrast the functional decline associated with aging. Hormone treatments may include growth hormone (GH), insulin‐like growth factor I (IGF‐I) signaling, dehydroepiandrosterone (DHEA), melatonin, testosterone, progesterone, and estrogen. In the 1990s, DHEA was exalted (...) as a possible candidate for the “fountain of youth.” Several experiments on animals have shown that DHEA is a multifunctional adrenal steroid with immune function enhancement, anti‐diabetic, anti‐cancer, and anti‐aging effects. The ethical questions concerning the extension of the lifespan belong to two distinct areas: the area of individual morality and the area of social morality. (shrink)

Awareness structures by Fagin, Halpern (Artif Intell 34:39–76, 1988) (FH) feature a syntactic awareness correspondence and accessibility relations modeling implicit knowledge. They are a flexible model of unawareness, and best interpreted from an outside modeler’s perspective. Unawareness structures by Heifetz et al. (J Econ Theory, 130:78–94, 2006, Games Econ Behav 62:305–324, 2008) (HMS) model awareness by a lattice of state spaces and explicit knowledge via possibility correspondences. Sublattices thereof can be interpreted as subjective views of agents. Open questions include (1) (...) how implicit knowledge can be defined in HMS structures, and (2) in which way FH structures can be extended to model the agents’ subjective views. In this paper, we address (1) by defining implicit knowledge such that it is consistent with explicit knowledge in HMS models. We also introduce a variant of HMS models that instead of explicit knowledge, takes implicit knowledge and awareness as primitives. Further, we address (2) by introducing a category of FH models that are modally equivalent relative to sublanguages and can be interpreted as agents’ subjective views depending on their awareness. These constructions allow us to show an equivalence between HMS and FH models. As a corollary, we obtain soundness and completeness of HMS models with respect to the Logic of Propositional Awareness, based on a language featuring _both_ implicit and explicit knowledge.

We recently demonstrated, by means of short latency afferent inhibition (SAI), that before an imagined movement, during the reaction time (RT), SAI decreases only in the movement-related muscle (sensorimotor modulation) and that a correlation exists between sensorimotor modulation and motor imagery (MI) ability. Excitatory anodal transcranial direct current stimulation (a-tDCS) on M1 could enhance the MI outcome; however, mechanisms of action are not completely known. Here, we assessed if a-tDCS on M1 prior to an MI task could affect sensorimotor modulation. (...) Participants imagined abducting the index or little finger in response to an acoustic signal. SAI was evaluated from the first dorsal interosseus after the “go” signal, before the expected electromyographic (EMG) activity. Participants received 20-min 1.5 mA a-tDCS or sham-tDCS on M1 on two different days, in random order. Results showed that a-tDCS on M1 increases the sensorimotor modulation consisting of a weakening of SAI after the Go signal with respect to sham-tDCS, in the movement-related muscle right before the beginning of MI. These results suggest that a-tDCS on M1 further potentiate those circuits responsible for sensorimotor modulation in the RT phase of MI. Increased sensorimotor modulation during MI may be one of the mechanisms involved in MI improvement after a-tDCS over M1. (shrink)

This article examines continuity and change in Star trek’s expression of the American Frontier Myth, moving from an American ideal of imperialist expansion across an unlimited feminized landscape and destruction of Indians and animals in the myth’s early form, to one of benevolent redemption of the Other as misguided or evil alien in the unlimited expanse of outer space in early Star Trek. Analysis of symbol and narrative in Star Trek Voyager show further change, as feminist and environmental ethics are (...) included. Now, movement is toward earth rather than away from it, raced and gendered Others are often internalized rather than projected onto Indians and aliens, and nature is vulnerable and spiritual rather than unlimited and inert. Though women and nature are still linked and idealized as selfless givers, progress is also made as women gain equal rank and air time and men take on some traditionally feminine roles. (shrink)

Name der Zeitschrift: Nietzscheforschung Jahrgang: 21 Heft: 1 Seiten: 231-242.

Nietzsche calls himself a “psychologist [Psychologe]” in a few passages of his published works. Furthermore—and mainly due to his intense interest in the scientific debates of his time, which involved figures such as Hartmann, Schopenhauer, Gerber, Helmholtz, and Zöllner—Nietzsche’s early philosophical thought can be regarded as clearly “permeated” by his concern with the unconscious. The combination of psychology and this concern with the unconscious..

An extended visual exploration of Brooklyn and its inhabitants viewed from a bus window frame. The project was conceived as a symbolic photographic portrait of America in this specific time of history, a time of transition and transformation deeply affected by the global economic crisis and its consequences on society, politics and culture.

The focus group held in Bologna on 2 October 2005 revolved around the relationships between ‘body’, ‘sexuality’ and ‘precarity’, which are concepts at the heart of the reflections and political agenda of the feminist and Gay, Lesbian, Bisexual, Transgender and Queer (GLBTQ) movements in Italy.

This study relies on environmental stewardship, a stakeholder-enlarged view of stewardship theory, and institutional theory to analyze the relationship between CEO compensation and firms’ environmental commitment in a worldwide sample of 520 large listed firms. Our findings show that environment friendly firms pay their CEOs less total compensation and rely less on incentive-based compensation than environment careless firms. This negative relationship is stronger in institutional contexts where national environmental regulations are weaker. Our findings have important theoretical meaning and practical implications. (...) Results show that CEOs do not necessarily act opportunistically; rather some of them may be willing to act as stewards of the natural environment and accept a lower, less incentive-based compensation from environment friendly firms. This study also provides evidence of the important influence of the institutional context in setting-up CEO compensation as the relationship is stronger when national environmental regulations are weaker. Our findings question the universal validity of agency theory in explaining CEO compensation. Compensation based on pecuniary incentives might be less indicated to motivate CEOs who feel rewarded by playing a stewardship role for environment friendly firms. When designing compensation for CEOs, compensation committees and external compensation advisors should consider psychological and institutional factors that might affect CEO motivation. (shrink)

Since the 1970s, many Anglo-American studies have investigated the theme of corporate social responsibility (CSR) and its costs and benefits. Most studies have tried to test, largely in samples of multiple industries, the relationship between corporate social performance (CSP) and corporate financial performance (CFP). These analyses, however, have produced conflicting results and any attempt to give a generalized and coherent conclusion has proved inadequate. This article examines the ways CSP can be proxied and investigates the possible relationship between CSP (measured (...) by ethical rating) and CFP (measured by market and accounting ratios) in the banking sector using correlation methodology. It emerges that there is no statistically significant link between CSP and CFP. (shrink)
