The concept of indiscernibility in a structure is analysed with the aim of emphasizing that in asserting that two objects are indiscernible, it is useful to consider these objects as members of (the domain of) a structure. A case for this usefulness is presented by examining the consequences of this view to the philosophical discussion on identity and indiscernibility in quantum theory.

da Costa’s conception of being modifies that of Quine to incorporate relativization to non-classical logics. A naturalistic view of this conception is discussed. This view tries to extend to logic some ideas of Maddy’s naturalism concerning mathematics.

We study the computability-theoretic complexity and proof-theoretic strength of the following statements: (1) "If X is a well-ordering, then so is ε X ", and (2) "If X is a well-ordering, then so is φ(α, X)", where α is a fixed computable ordinal and φ represents the two-placed Veblen function. For the former statement, we show that ω iterations of the Turing jump are necessary in the proof and that the statement is equivalent to ${\mathrm{A}\mathrm{C}\mathrm{A}}_{0}^{+}$ over RCA₀. To prove the (...) latter statement we need to use ω α iterations of the Turing jump, and we show that the statement is equivalent to ${\mathrm{\Pi }}_{{\mathrm{\omega }}^{\mathrm{\alpha }}}^{0}{-\mathrm{C}\mathrm{A}}_{0}$ . Our proofs are purely computability-theoretic. We also give a new proof of a result of Friedman: the statement "if x is a well-ordering, then so is φ(x, 0)" is equivalent to ATR₀ over RCA₀. (shrink)

We prove that the maximal order type of the wqo of linear orders of finite Hausdorff rank under embeddability is φ2, the first fixed point of the ε-function. We then show that Fraïssé’s conjecture restricted to linear orders of finite Hausdorff rank is provable in +“φ2 is well-ordered” and, over , implies +“φ2 is well-ordered”.

Pensar nas cidades que construímos é constituir também a construção de um olhar para os corpos que ocupam esses espaços. Neste trabalho, buscamos mergulhar na experiência da sexualidade-em-situação de homens gays da cidade de Campos dos Goytacazes - RJ. A história da construção da cidade se entrelaça em memórias de opressão e violências que até hoje se perpetuam na situação dos corpos desses homens, que a partir de suas trajetórias e experiências, resgatam memórias das situações que viveram e ainda vivem (...) na cidade. Há, portanto, a urgência de um imperativo de mudança que vai acontecendo individualmente e coletivamente, indicando que as suas experiências reivindicam e extrapolam as estruturas que um dia impediram seus corpos de existirem.

This paper compares Kant’s and Leibniz’s views on the relation between knowing subjects and known objects. Kant discusses Leibniz’s philosophy in the ‘Amphiboly’ section of the first Critique. According to Kant, Leibniz’s main error is mistaking objects in space and time for mind-independent things in themselves, that is, for monads. The paper argues that, pace Kant, Leibniz regards objects in space and time as mind-dependent. A deeper divergence between the two philosophers concerns knowing subjects. For Leibniz, they are substances. For (...) Kant, we cannot know whether they are substances. Kant conceives of knowing subjects as complex systems of cognitive capacities. (shrink)

In (Fund Math 60:175–186 1967), Wolk proved that every well partial order (wpo) has a maximal chain; that is a chain of maximal order type. (Note that all chains in a wpo are well-ordered.) We prove that such maximal chain cannot be found computably, not even hyperarithmetically: No hyperarithmetic set can compute maximal chains in all computable wpos. However, we prove that almost every set, in the sense of category, can compute maximal chains in all computable wpos. Wolk’s original result (...) actually shows that every wpo has a strongly maximal chain, which we define below. We show that a set computes strongly maximal chains in all computable wpo if and only if it computes all hyperarithmetic sets. (shrink)

Isaac de Pinto was an active financier, economist and homme de lettres. Descending from a Jewish family of Portuguese origin, he lived in Amsterdam, Paris and London. Throughout his life, he enjoyed close relationships and made regular contact with important figures of the European Enlightenment. The main purpose of this article is to show that the concern with the Jewish problems, namely those relating to the difficult economic situation of the Portuguese nation in Amsterdam in the second half of the (...) eighteenth century, is a key factor in explaining the ongoing moral and apologetic dialogues that Isaac de Pinto maintained separately with Voltaire and Diderot. ☆ The authors are most grateful for the comments and suggestions provided by Antoin Murphy and two referees of this journal.

The plays written about AIDS in the past dozen years form a radical canon establishing gay men as the locus for public attention. These plays have been all but silent in their representation of women with AIDS. This article examines the marginalized women in early plays such as The Normal Heart and As Is, and the women more central to later plays such as The Baltimore Waltz, Before It Hits Home, and Patient A. It foregrounds some of the most problematic (...) issues surrounding the AIDS virus: the perception of women as vectors of disease for men and unborn children, the insistent representation of women as mothers and caregivers, and the denial of patterns of abuse, sexual exploitation, and poverty which contribute to the marginalization of woman and people of color.

Cinematic virtual reality (CVR) offers filmmakers a wide range of possibilities to explore new techniques regarding movie scripting, shooting and editing. Despite the many experiments performed so far both with both live action and computer-generated movies, just a few studies focused on analyzing how the various techniques actually affect the viewers’ experience. Like in traditional cinema, a key step for CVR screenwriters and directors is to choose from which perspective the viewers will see the scene, the so-called point of view (...) (POV). The aim of this paper is to understand to what extent watching an immersive movie from a specific POV could impact the narrative engagement (NE), i.e., the viewers’ sensation of being immersed in the movie environment and being connected with its characters and story. Two POVs that are typically used in CVR, i.e., first-person perspective (1-PP) and external perspective (EP), are investigated through a user study in which both objective and subjective metrics were collected. The user study was carried out by leveraging two live action 360° short films with distinct scripts. The results suggest that the 1-PP experience could be more pleasant than the EP one in terms of overall NE and narrative presence, or even for all the NE dimensions if the potential of that POV is specifically exploited.

Agreement technologies refer to a novel paradigm for the construction of distributed intelligent systems, where autonomous software agents negotiate to reach agreements on behalf of their human users. Smart Cities are a key application domain for agreement technologies. While several proofs of concept and prototypes exist, such systems are still far from ready for being deployed in the real-world. In this paper we focus on a novel method for managing elements of smart road infrastructures of the future, namely the case (...) of auction-based road intersections. We show that, even though the key technological elements for such methods are already available, there are multiple non-technical issues that need to be tackled before they can be applied in practice. For this purpose, we analyse legal and ethical implications of auction-based road intersections in the context of international regulations and from the standpoint of the Spanish legislation. From this exercise, we extract a set of required modifications, of both technical and legal nature, which need to be addressed so as to pave the way for the potential real-world deployment of such systems in a future that may not be too far away.

In this note, the problem of tracking random references and rejecting random perturbations in a quadrotor, both generated by an auxiliary system named exosystem, is solved by extending the deterministic tracking problem to the area of stochastic processes. Besides, it is considered that only a part of the state vector of the quadrotor is available through measurements. As a consequence, the state vector of the plant must be estimated in order to close the control loop. On this basis, a controller (...) to track random references and to reject random perturbations is developed by combining a Kalman filter to estimate the references and perturbations of an exosystem and an observer to estimate the states of a quadrotor. Besides, to obtain a more practical controller, the analysis is carried out in discrete time. Numerical simulations are used in a quadrotor to confirm the validity and effectiveness of the proposed control. (shrink)

When the language-dominant hemisphere is damaged by a focal lesion, the brain may reorganize the language network through functional and structural changes known as adaptive plasticity. Adaptive plasticity is documented for triggers including ischemic, tumoral, and epileptic focal lesions, with effects in clinical practice. Many questions remain regarding language plasticity. Different lesions may induce different patterns of reorganization depending on pathologic features, location in the brain, and timing of onset. Neuroimaging provides insights into language plasticity due to its non-invasiveness, ability (...) to image the whole brain, and large-scale implementation. This review provides an overview of language plasticity on MRI with insights for patient care. First, we describe the structural and functional language network as depicted by neuroimaging. Second, we explore language reorganization triggered by stroke, brain tumors, and epileptic lesions and analyze applications in clinical diagnosis and treatment planning. By comparing different focal lesions, we investigate determinants of language plasticity including lesion location and timing of onset, longitudinal evolution of reorganization, and the relationship between structural and functional changes.

The influence of externally focused organizational capabilities on the generation of proactive environmental strategies was examined under contingenteffects of uncertainty in the general business environment in 134 North American and European ski resorts. Capabilities of strategic proactivity and continuous innovation were found to be associated with proactive environmental strategies. Managerial perceptions of uncertainty in the general business environment were found to moderate the deployment of the capability of continuous innovation at all levels of uncertainty and stakeholder engagement at low and (...) average levels of uncertainty. The study contributes to the resource-based view by illuminating an important contingency under which these capabilities are likely to be deployed to generate such a strategy. (shrink)

This paper examines the influence of internal barriers on the relationship between the organizational capability of stakeholder integration and proactive environmental strategies. We adopt a moderate hierarchical regression model to test the hypotheses using data from a sample of 73 managers in the business education industry. The paper contributes to stakeholder theory by showing that stakeholder integration positively influences the development of proactive environmental strategies when managers perceive internal barriers to the development of such strategies. This article also explores an (...) ethical dilemma—managers may use the stakeholder integration capability to support their own interests rather than to benefit stakeholders. (shrink)

Este artículo explora el concepto de trauma colectivo y su aplicación en el contexto histórico y social de las sociedades latinoamericanas. La transferencia del término «trauma colectivo» desde el campo del conocimiento psicológico a la esfera social e histórica plantea preguntas sobre su legitimidad y marco conceptual. El estudio examina la fidelidad de esta transferencia conceptual y su relación con la comprensión psicoanalítica temprana de los fenómenos traumáticos. El contexto cultural europeo de finales del siglo xix y principios del siglo (...) xx proporcionó la base para teorizar las consecuencias de experiencias intensas y violentas, lo que resultó en el concepto de «neurosis traumática», influenciado significativamente por el trabajo de Freud. El artículo discute la apropiación de herramientas psicoanalíticas en la crítica histórica y cultural para comprender eventos que desafían marcos tradicionales y la inteligibilidad social, como el Holocausto. La noción del trauma como una fuerza enigmática y recurrente en la experiencia histórica se explora a través del enfoque de los estudios del trauma. El artículo pone de relieve a destacados y destacadas académicas en este campo y su uso de conceptos psicoanalíticos, demostrando la preservación y aplicación significativa de estas nociones en la comprensión de fenómenos históricos y colectivos. Al acortar la brecha entre las experiencias psicológicas individuales y los traumas colectivos, los estudios del trauma ofrecen un enfoque único para interpretar y representar eventos que resisten las narrativas históricas tradicionales.

In this paper intergenerational dimensions of reproductive behavior are studied within the context of the experience of a mid-sized Spanish town just before and during the demographic transition. Different indicators of reproduction are used in bivariate and multivariate approaches. Fertility shows a small, often statistically significant intergenerational dimension, with stronger effects working through women and their mothers than those stemming from the families of their husbands. These effects are materialized mainly through duration-related fertility variables, are singularly absent for variables such (...) as age at first birth or birth intervals, and are much stronger in the case of firstborn daughters than with later siblings. There is a substantial increase in the strength of intergenerational effects during the course of the demographic transition, most visible in age at last birth and duration of reproduction (between women and their mothers), as well as in the effects working through the families of their husbands. These results underscore the on-going importance of biological dimensions of reproduction as well as the way attitudes toward reproduction are taught within the family. The changes identified in this study suggest that the transmission of values and attitudes became more important for reproductive outcomes during this period of demographic modernization. (shrink)

The 'Enciclopedia Filosofica' is an encyclopaedia of philosophical topics promoted by the Centre for Philosophical Studies of Gallarate and published, in its third and last edition in 2006, by the Bompiani publishing house in Milan.

A growing number of recreational races are being held in different locations, drawing many local and visiting runners. This study examined the relationships between quality, value, satisfaction, and loyalty among runners in a recreational race and examines potential differences in relationships between these constructs based on the runners’ experience. The participants were 985 runners with a mean age of 40.74±9.41years. Validated, reliable ad hoc instruments were used. A multi-group analysis was performed to ascertain the existence of relationships between the constructs (...) and differences in the relationships between the different study groups. The results show that quality is a direct antecedent of value and satisfaction. Value is directly related to satisfaction and indirectly related to loyalty. Satisfaction is related to the loyalty of participants in the race. Differences in the relationship between satisfaction and loyalty were dependent upon the runners’ experience. Loyalty to a race depends primarily on satisfaction and is modified by the runners’ experience. (shrink)

Behavioral interventions have shown promising neuroprotective effects, but the cascade of molecular, brain and behavioral changes involved in these benefits remains poorly understood. Projecte Moviment is a 12-week multi-domain, single-blind, proof-of-concept randomized controlled trial examining the cognitive effect and underlying mechanisms of an aerobic exercise, computerized cognitive training and a combined groups compared to a waitlist control group. Adherence was > 80% for 82/109 participants recruited. In this study we report intervention-related changes in plasma biomarkers and structural-MRI and how they (...) related to changes in physical activity and individual variables and their potential role as mediators in the cognitive changes. Our results show that although there were no significant changes in molecular biomarker concentrations in any intervention group, changes in ICAM-1 and SDF1-α were negatively associated with changes in physical activity outcomes in AE and COMB groups. Brain volume changes were found in the CCT showing a significant increase in precuneus volume. Sex moderated the brain volume change in the AE and COMB groups, suggesting that men may benefit more than women. Changes in molecular biomarkers and brain volumes did not significantly mediate the cognitive-related benefits found previously for any group. This study shows crucial initial molecular and brain volume changes related to lifestyle interventions at early stages and highlights the value of examining activity parameters, individual difference characteristics and using a multi-level analysis approach to address these questions.

Antonio Rosmini-Serbati was one of the first natural law scholars to bring natural law thinking into a conversation with the market economic order that was beginning to emerge in Europe in the 19th century. His reflections on matters such as the origin, nature, and limits of private property, the role of the state, and the nature of human reason show him to be a unique, innovative thinker who nonetheless was determined to work within the parameters of Catholic doctrine. Many (...) of these ideas are concretized in his seminal work The Constitution Under Social Justice, a text that has profound instights to offer those today seeking to integrate theology, philosophy, and economics into their conceptions of a social order that aspires to be both free and just.
