Seen from the point of view of evaluation conditions, a usual way to obtain a connexive logic is to take a well-known negation, for example, Boolean negation or de Morgan negation, and then assign special properties to the conditional to validate Aristotle’s and Boethius’ Theses. Nonetheless, another theoretical possibility is to have the extensional or the material conditional and then assign special properties to the negation to validate the theses. In this paper we examine that possibility, not sufficiently explored in (...) the connexive literature yet.We offer a characterization of connexive negation disentangled from the cancellation account of negation, a previous attempt to define connexivity on top of a distinctive negation. We also discuss an ancient view on connexive logics, according to which a valid implication is one where the negation of the consequent is incompatible with the antecedent, and discuss the role of our idea of connexive negation for this kind of view.

Nuestro principal objetivo en este trabajo es el de analizar si es posible construir sistemas lógicos temporales-epistémicos lo suficientemente satisfactorios. Sin embargo, las principales dificultades para lograr este propósito provienen del hecho de tener que combinar una perspectiva temporal absoluta con una perspectiva epistémica relativa a cada agente; es decir, por un lado, los instantes de tiempo vienen determinados desde el punto de vista de un observador situado fuera del mundo, y, por otro lado, las alternativas epistémicas de cada agente (...) son relativas a dicho agente. Pensamos que algunas de estas dificultades podrían ser superadas con la ayuda de las lógicas híbridas, puesto que este tipo de lógicas simplifica la combinación de sistemas temporales y epistémicos, y así podemos evitar tener que construir modelos excesivamente complicados. Our main goal in this paper is to analyse if it is possible to build some suitable Temporal-Epistemic Systems. However, the main difficulties in order to aim this goal come from the fact of having to combine an absolute temporal perspective with a relative epistemic perspective; that is, on one hand, temporal points are determined from the point of view of an observer placed outside the world, and, on the other hand, the epistemic alternatives of each agent are relative to that agent. We think that some of these difficulties could be solved with the help of hybrid logics, because this kind of logics simplifies the combination of temporal and epistemic systems, and so we can avoid building highly complicated models.

Research on salesperson creativity remains as one of the most under-researched topics in the sales literature despite the evidence that encouraging creativity in the sales domain is a source of competitive advantage. This paper aims to fill this research gap by exploring the influence of perceived ethical climate on salesperson creative performance, paying special attention to the role that emotions play in this process. Data provided by 176 supervisor–salesperson dyads confirm that the trust/responsibility dimension of an ethical climate is positively (...) related to salesperson creative selling by increasing salespeople's organizational pride. Similarly, the perception of unethical selling practices negatively affects salesperson organizational pride, reducing the expression of creative behaviors. Moreover, the negative effect of unethical selling practices on creative performance is stronger (more negative) when salespeople's identification with an organization increases. Managerial implications and future research directions are also addressed. (shrink)

I argue that scientists should adopt a sexual orientation view that includes ‘internal’ sexual orientation markers such as desire, fantasies, and attraction, plus self-identification, and that these two markers should line up. By ‘internal’ markers, I mean inner states or processes of the agent. This can be contrasted with ‘external markers’, by which I mean, behaviours of the agent. I begin by critically reviewing four genetic studies of sexual orientation that are representative of the literature. I look at how each (...) of these studies deploy the concept of ‘sexual orientation’, and show a) that they are each using different notions, and b) that none of the notions are satisfactory. I argue that these accounts have a very limited amount of predictive and explanatory power. Following this, I outline what an account of sexual orientation that has more predictive and explanatory power might look like. I argue that this account will be one that includes internal markers and self-identification. (shrink)

A patent is a property granted to any new shape, configuration or arrangement of elements, of any device, tool, instrument, mechanism or other object or part thereof, that allows for a better or different operation, use or manufacture of the object that incorporates it or that provides it with some utility, advantage or technical effect that it did not have before. As a document, a patent really is a title that recognizes the right to exploit the patented invention exclusively, preventing (...) others from making, selling or using it without the consent of the owner. The fact of making a patent is motivated by the fact of promoting creativity, hindering competition in the market as only one person holds the patent, thus protecting the initial investment and fighting against plagiarism. Patents are available to the public for dissemination and general knowledge. It is generally recognized in the specialized literature that patents can be used as an indicator to calculate the results generated by research and development activities, being a very useful indicator to measure various social, economic or technological aspects. For this reason, it is of relevant interest to have tools or systems that allow us to obtain the patents developed in a specific period of time and to carry out analyses of various economic and social factors. These analyses can serve to obtain a social perspective of society’s progress in the technological field, and this is why an analysis of patents is of our interest. This paper proposes a platform specifically designed to obtain knowledge about patents as an indicator of Spanish social, economic or technological aspects. For this purpose, the platform retrieves, analyses and visualizes functionalities that represent data on the landscape of patents obtained from the Spanish Patent and Trademark Office as a particular case of study.

En este artículo discutimos la tesis de Jc Beall según la cual no hay negación lógica. Evaluamos la solidez del argumento con el que defiende su tesis y presentamos dos razones para rechazar una de sus premisas: que la negación tiene que ser excluyente o exhaustiva. La primera razón involucra una presentación alternativa de las reglas de la negación en sistemas de secuentes diferentes al que Beall presupone. La segunda razón establece que la negación no tiene que ser excluyente o (...) exhaustiva. (shrink)

The idea that appearances provide justifications for beliefs—the principle of phenomenal conservatism—is self-evidently true. In the case of cognitive penetration, however, it seems that certain irrational etiologies of a belief may influence the epistemic quality of that belief. Susanna Siegel argues that these etiologies lead to ‘epistemic downgrade.’ Instead of providing us with a decisive objection, cognitive penetration calls for us to clarify our epistemic framework by understanding the formative parts of appearances. In doing so, the two different but inseparable (...) ideas of sensation and intellection provide us with a basis of our appearances. These appearances, in turn, provide us with the objective evidence needed to test our judgements. Thus, the extra-sensory concepts of intellectual identification and the appearances they help form become an epistemic groundwork. (shrink)

This study aimed to determine the predictive character of organizational socialization and occupational positive mental health on organizational commitment in higher education teachers. A sample of 279 teachers from higher education institutions who signed an informed consent form was used. Fifty-four point five percent of the participants were women, with a mean age of 44.05 years. The participants completed the Organizational Socialization Inventory, the Positive Occupational Mental Health Questionnaire and the Organizational Commitment Scale, and for data analysis descriptive statistics, correlation (...) analysis and multiple linear regression with stepwise method were applied, entering each dimension of organizational commitment separately as a dependent variable. As a result, moderate to weak correlations were identified between the study variables, and it was found that the final models indicate that the future perspectives and socio-affective dimensions predict affective commitment by 38%; that future perspectives, spirituality and age predict normative commitment by 22.8%; and that the future perspectives dimension predicts commitment of continuity by 9.2%. It is concluded that teachers’ expectations about their development in the institution, as well as their interactions at the socio-affective and spiritual level with the work context, are factors that partially influence their attachment to the educational organization.

Quality standards fulfilment is an essential task in manufacturing processes that involves high costs. One target is to avoid the presence of burrs in the edge of machine workpieces, which reduce the quality of the products. Furthermore, they are not easily removed since the part can even be damaged. In this paper, we propose an optimized Convolutional Neural Network, to detect the presence of burrs in images of milling parts. Its design is focused on the optimization of classification (accuracy) and (...) performance metrics (training time and number of trainable parameters). The proposed architecture identifies burrs with a 91.16% accuracy in the test set, outperforming existing models as EfficientNetB0. It also reduces the number of trainable parameters from other models as AlexNet by 1.5 million. The prediction process just takes 48.39 milliseconds per image. Finally, in order to check if the model gets a high activation in the region of interest, a visual explanation of the model is also carried out by using Gradient-weighted Class Activation Mapping.

En la educación médica cubana se ha diseñado un currículo para el cumplimiento de su encargo social donde se inserta la enseñanza del inglés. Actualmente constituye una prioridad trabajar en la búsqueda de estrategias que favorezcan el perfeccionamiento idiomático de los egresados, en este sentido se desarrolló una investigación en la Filial de Ciencias Médicas de Colón con el objetivo de desarrollar la expresión oral en el inglés con fines específicos en el tercer año de la carrera de Medicina. Se (...) emplearon métodos como el análisis de documentos, la observación participante, y los registros anecdóticos. El sistema de actividades aplicado favorece la negociación de significados, toma de riesgos, mayor precisión al expresar ideas, así como el acercamiento del uso del idioma en situaciones reales con lo cual se logra mayor motivación, objetividad del aprendizaje e independencia, al emplear las habilidades lingüísticas para su desempeño profesional. In Cuban medical education, a curriculum in which English is integrated, is designed to fulfill a social mission. Presently, it is a priority to identify strategies that support the idiomatic improvement of graduates. To this end, an investigation was developed in the University of Medical Sciences of Matanzas at Colon Campus with the objective of developing speaking in English for Specific Purposes in the third-year of the medical program of study. Methods such as document analysis, participant observation, and review of anecdotal records were used. The resulting system of activities favors the negotiation of meaning, risk-taking, improved precision to express ideas and the expanded use of English language in real situations. This results in greater motivation, learning objectivity and independence to use language skills for their professional performance. (shrink)

Selective attention depends on goal-directed and stimulus-driven modulatory factors, each relayed by different brain rhythms. Under certain circumstances, stress-related states can change the balance between goal-directed and stimulus-driven factors. However, the neuronal mechanisms underlying these changes remain unclear. In this study, we explored how psychosocial stress can modulate brain rhythms during an attentional task and a task-free period. We recorded the EEG and ECG activity of 42 healthy participants subjected to either the Trier Social Stress Test, a controlled procedure to (...) induce stress, or a comparable control protocol, flanked by an attentional task, a 90 s of task-free period and a state of anxiety questionnaire. We observed that psychosocial stress induced an increase in heart rate, self-reported anxiety, and alpha power synchronization. Also, psychosocial stress evoked a relative beta power increase during correct trials of the attentional task, which correlates positively with anxiety and heart rate increase, and inversely with attentional accuracy. These results suggest that psychosocial stress affects performance by redirecting attentional resources toward internal threat-related thoughts. An increment of endogenous top-down modulation reflected an increased beta-band activity that may serve as a compensatory mechanism to redirect attentional resources toward the ongoing task. The data obtained here may contribute to designing new ways of clinical management of the human stress response in the future and could help to minimize the damaging effects of persistent stressful experiences.

El trabajo intenta mostrar, a partir de una introducción historiografica, uno de los modos posibles en que pueden vincularse el sistema filosófico de Nicolas de Cusa [1401 -1464], a traves de la reformulación que hace el Cusano de la coincidentia oppositorum en el Trialogus De possest' [1460], con la teoria sustancialista de Baruch de Spinoza [1632 -1677], tal como es presentada en el Liber Primus de su Ethic.

Normal 0 21 false false false MicrosoftInternetExplorer4 On February 12, 1440 Nicholas of Cusa (1401-1464) concludes in his birthplace of Kues drafting the first major systematic formulation of his thinking: De docta ignorantia . The main category of his metaphysics in this context, i.e. the maximum , is analyzed and interpreted by him on three considerations: the maximum in an absolute sense, as contracted and finally as absolute and contracted, at the same time. In the context of the First Book, (...) which presents the singular methodology of the docta ignorantia , considers the maximum in itself in light of the paradoxical concept of coincidentia oppositorum in the absolute. In the final chapters of this first book tackles the critical of the theological discourse and thus, the problem of the ineffable name of maximum et minimum absolutum . Hence the purpose of this work is the further on cusan’s evaluation of language problem as it shows through treatment of the theological discourses and divine names that emerge from them, in light of the way of docta ignorantia.

In this paper I explore whether three different approaches to connexivity – namely, Lewis and Langford’s, Wansing’s and Egré and Politzer’s – can be non-trivially related. Lewis and Langford’s approach consists of the definition of the conditional in terms of consistency via the definition of possibility in terms of consistency and Lewis’ definition of the (strict) conditional in terms of possibility; Wansing’s approach is based on his definition of the falsity condition for the conditional as “if A is true then (...) B is false”; Egré and Politzer’s approach relies on the modalization of the falsity condition for the conditional in its conditional form (A→◇~B). With this background in mind, I build upon Estrada-González’s work relating connexivism and possibilism, the thesis according to which everything is possible. Estrada-González’s work relates Lewis and Langford’s connexive approach with Nelson’s idea that every proposition is self-consistent. He does so using a fragment of LP augmented with a special conditional. This relation has resulted in the study and postulation of several truth-functional modalities, some of which have already been discussed elsewhere. I employ several truth-functional modalities to evaluate Egré and Politzer’s falsity conditions for the conditional. I show that in using Béziau’s truth-functional modality ◇B, definable in Estrada-González’s framework, one can retain in a single framework the three different approaches. More specifically, distinguishing the notion of logical equivalence from the notion of interderivability and these two from the notion of coimplication, it is possible to relate ~(A→B) and (A→◇~B) as interderivable schemas and in a valid biconditional. I also show some consequences of this for Béziau’s negative appraisal of three-valued truthfunctional modalities. (shrink)

The idea has been largely studied in its categorial aspect, but hardly in its metaphysical onto-theological constitution. This is, nevertheless, the point of González´s “Metaphysical relation between finite and infinite by Nicolaus of Cusa”. The basic assumptions are: 1) There is a disproportion between finite and infinite; 2) As a consequence of it, the relation between immanence and transcendence appears; 3) The operational relationship between finite and infinite is the creation, which is necessarily asymmetric. Besides, the Cusano´s vision of (...) the relation finite-infinite can be applied to the human being -holds up González, together with Polo-, and shows that human person is a relation to the origin. The notion of relation is analogous. But, whether the Cusano´s philosophy allows maintaining this thesis is dubious. (shrink)

Software vulnerabilities are the root cause for a multitude of security problems in computer systems. Owing to their efficiency and tight control over low-level system resources, the C and C++ programming languages are extensively used for a myriad of purposes, from implementing operating system kernels to user-space applications. However, insufficient or improper memory management frequently leads to invalid memory accesses, eventually resulting in memory corruption vulnerabilities. These vulnerabilities are used as a foothold for elaborated attacks that bypass existing defense methods. (...) In this paper, we summarise the main memory safety violation types (i.e. memory errors), and analyse how they are exploited by attackers and the main mitigation methods proposed in the research community. We further systematise the most relevant techniques with regards to memory corruption identification in current programs. (shrink)
