The logic BN4 was defined by R.T. Brady in 1982. It can be considered as the 4-valued logic of the relevant conditional. E4 is a variant of BN4 that can be considered as the 4-valued logic of entailment. The aim of this paper is to define reduced general Routley-Meyer semantics for BN4 and E4. It is proved that BN4 and E4 are strongly sound and complete w.r.t. their respective semantics.

Valerie Plumwood introduced in "Some false laws of logic" a series of arguments on how the rules Exported Syllogism, Disjunctive Syllogism, Commutation, and Exportation are not acceptable. Based on this we define the class of Plumwood algebras - logical matrices that do not verify any of these theses. Afterwards we provide conditional variants of the characteristic matrix of the logic RM3 that are also Plumwood algebras. These matrices are given an axiomatization based on First Degree Entailment and are endowed with (...) Belnap-Dunn Semantics. Finally we provide results of Soundness and Completeness in the strong sense for each of the defined variants. (shrink)

The logic BN4 can be considered as the 4-valued logic of the relevant conditional and the logic E4, as the 4-valued logic of entailment. The aim of this paper is to endow E4 with a 2-set-up Routley-Meyer semantics. It is proved that E4 is strongly sound and complete w.r.t. this semantics.

In diesem Beitrag möchte ich mich darauf beschränken, einige Aspekte von Fichtes Verhältnis zu Kant zu berücksichtigen, die mir sowohl für das Verständnis Fichtes als auch für das Verständnis Kants sehr lehrreich zu sein scheinen. Denn die Einsicht in die unterschiedlichen Auffassungen des alten und des jungen Denkers läßt um so mehr da, wo der zweite meint, den ersten bloß zu wiederholen, treu zu interpretieren oder allenfalls treu weiterzudenken, den Geist der beiden philosophischen Ansätze am deutlichsten zutage treten. Den manchmal (...) unbestimmten Ausdruck »Geist« darf man in diesem Fall wohl verwenden, da die Textstellen, die dem Vergleich feste Bezugspunkte angeben, nicht isoliert dastehen, sondern jeweils in zwei verschiedene und scharf konturierte philosophische Ansätze hinein konvergieren.

Fission of cellular membranes is ubiquitous and essential for life. Complex protein machineries, such as the dynamin and ESCRT spirals, have evolved to mediate membrane fission during diverse cellular processes, for example, vesicle budding. A new study suggests that non-specialized membrane-bound proteins can induce membrane fission through mass action due to protein crowding. Because up to 2/3 of the mass of cellular membranes is contributed by proteins, membrane protein crowding is an important physiological parameter. Considering the complexity of membrane shape (...) transitions during a fission reaction, spatial and temporal variability in protein distribution, and the abundance of intrinsically disordered regions in proteins on an invaginating membrane, protein crowding can have diverse consequences for fission in the cell. The question is, how and to what extent this mechanism combines with the action of dedicated fission machineries. Membrane fission, which is required for formation of vesicles or cytokinesis, can be carried out by specialized proteins like dynamin and the ESCRT complex. Recent work suggests that fission of cellular membranes, which are densely packed with proteins, can also be induced by protein crowding due to high entropic tension. (shrink)

J’analyserai des déclarations et des idées proposées par Galilée dans son Sidereus Nuncius et j’en proposerai des interprétations non conventionnelles. Je vais essayer de montrer qu’avec un esprit logique et de nouvelles hypothèses, il est possible de parvenir à de nouvelles interprétations possibles de la pensée de Galilée.

We investigated motor resonance in children using a priming paradigm. Participants were asked to judge the weight of an object shortly primed by a hand in an action-related posture or a non action-related one . The hand prime could belong to a child or to an adult. We found faster response times when the object was preceded by a grasp hand posture . More crucially, participants were faster when the prime was a child’s hand, suggesting that it could belong to (...) their body schema, particularly when the child’s hand was followed by a light object . A control experiment helped us to clarify the role of the hand prime. To our knowledge this is the first behavioral evidence of motor simulation and motor resonance in children. Implications of the results for the development of the sense of body ownership and for conceptual development are discussed. (shrink)

This article develops an analysis of disability according to which disabling conditions are properties of organisms embedded in sets of environments. We begin by presenting the three mainstream accounts of disability—the medical, social, and interactionist models—and rehearsing some known limitations. We argue that, because of their primary focus on etiology, all three models share, more or less implicitly, a problematic assumption. This is the tenet that disabilities are individual properties. The second part of the essay presents an “ecological” interpretation of (...) disability, inspired by classic and contemporary research on biological niches. Our proposal preserves many insights underlying extant approaches, while allowing a more accurate characterization of the nature and experience of disability. We conclude by drawing some general implications of our analysis. (shrink)

La crítica situación económica actual, ha potenciado que las empresas asuman sus responsabilidades y se instaure la cultura de la Responsabilidad Social. Este concepto se desarrolla tardíamente en España, pero las empresas actualmente son más conscientes de la necesidad de integrarla en su política estratégica. Partiendo de la base de que las empresas, en el desarrollo de su actividad cotidiana, cumplen con las leyes que les afectan, si desarrollan un sistema de gestión de la Responsabilidad Social (RS) adaptado a las (...) características de cada empresa, podrían obtener beneficios adicionales. La Norma Internacional ISO 26000 indica como implantar la RS en las empresas y la RS 10 fija los requisitos de acuerdo con la ISO 26000. En este trabajo se lleva a cabo una comparación crítica.

Communication campaigns often highlight environmental progress to encourage further pro-environmental behaviour. Consequently, the drop in carbon emissions caused by the COVID-19 restrictions has been framed as a positive environmental outcome of the pandemic. We conducted an experimental study with a US-representative sample (N = 500) to show that raising awareness of emissions reduction has the contrary effect: an increase in moral self-concept facilitated a negative spillover, namely, it reduced climate-friendly behavioural intentions. Normative influence was able to prevent this negative spillover (...) because activating environmental norms inhibited compensatory feelings. Besides, awareness of recent emissions reduction was less likely to increase the moral self-concept of participants with a strong environmental self-identity. Our findings demonstrate that environmental progress increases moral self-concept which, in turn, could cause a negative spillover (i.e., reduce climate-friendly low-carbon behaviour and increase climate-harmful high-carbon behaviour). Normative influences and environmental self-identity can inhibit this negative spillover. (shrink)

Tomas Aquinas defined truth as the correspondence between things and understanding. Castro Alves paints the horror of the slave nautical traffic. In his essay On the Concept of History, Walter Benjamin reminds us: “The tradition of the oppressed teaches us that the ‘emergency situation’ in which we live is the rule.” This ‘emergency situation’ was Fascism. Albert Camus defended his romance La Peste against the accusation of Roland Barthes that is was “dehors de l’histoire”, pointing out that it was not (...) only about the recent historical phenomenon of Fascism, but also about the permanent risk of its rebirth. Agnes Heller associates faith with prejudice and alienation. The following article will explore the Thomist concept of truth, Benjamin’s concept of history, Camus’ allegory of the plague, Agnes Heller’s notion of faith and Castro Alves’ powerful denouncement of slave traffic, to better criticize the phenomenon of post-truth, a rebirth of fascist information practices.

Bibliographic negligence, i.e. omission of citation of the relevant work of other researchers, is possibly the most common type of research misconduct, leading to unfair loss of priority of authorship and undermining the reward system of science. We report a case of bibliographic negligence which we recently suffered from a leading biomedical journal. The case is discussed in the context of the editorial policy of the journal and of relevant ethical guidelines. Scientific journals should develop codes of conduct for citations. (...) In addition, the implications and consequences of bibliographic negligence deserve thorough investigation. (shrink)

Emotional dysregulation, age, gender, and obesity are transdiagnostic risk factors for the development and maintenance of eating disorders. Previous studies found that patients with ED had less meaning in life than the non-clinical population, and that meaning in life acted as a buffer in the course of ED; however, to the data, there are no studies about the mediator role of meaning in life in association between the emotional dysregulation and the ED psychopathology.Objective: To analyze the mediating role of meaning (...) in life in the relationship between emotional dysregulation and the ED psychopathology in three samples with diverse risk factors for ED.Method: Sample 1, n = 153 undergraduate young women; sample 2, n = 122 participants with obesity; and sample 3, n = 292 participants with ED. Multiple mediation analysis was performed.Results: Sample 1: meaning in life showed a mediation effect between emotional dysregulation and the ED psychopathology, body satisfaction, and depression symptoms ; sample 2: meaning in life showed a mediation effect between emotional dysregulation and binge eating and purging behaviors and depression symptoms ; sample 3: meaning in life showed a mediation effect between emotional dysregulation and the ED psychopathology, body satisfaction, borderline symptoms, and hopelessness.Conclusions: These studies suggest the importance of considering meaning in life as a variable in the onset and maintenance of ED.

There are few successful applications of automated reasoning over OWL-formalised bio-ontologies, and requirements are often unclearly formulated. Of what is available, usage and prospective scenarios of automated reasoning is often different from the straightforward classification and satisfiability. We list nine types of scenarios and specify the requirements in more detail. Several of these requirements are already possible in practice or at least in theory, others are in need of further research, in particular regarding the linking of the OWL ontology to (...) data, reasoning over roles, and dynamically linking modular ontologies.

An intermediate stage in Hrushovski’s construction of flat strongly minimal structures in a relational language L produces ω-stable structures of rank ω. We analyze the pregeometries given by forking on the regular type of rank ω in these structures. We show that varying L can affect the isomorphism type of the pregeometry, but not its finite subpregeometries. A sequel will compare these to the pregeometries of the strongly minimal structures.
