In the Reality we know, we cannot say if something is infinite whether we are doing Physics, Biology, Sociology or Economics. This means we have to be careful using this concept. Infinite structures do not exist in the physical world as far as we know. So what do mathematicians mean when they assert the existence of ω? There is no universally accepted philosophy of mathematics but the most common belief is that mathematics touches on another worldly absolute truth. Many mathematicians (...) believe that mathematics involves a special perception of an idealized world of absolute truth. This comes in part from the recognition that our knowledge of the physical world is imperfect and falls short of what we can apprehend with mathematical thinking. The objective of this paper is to present an epistemological rather than an historical vision of the mathematical concept of infinity that examines the dialectic between the actual and potential infinity.

Human language has the characteristic of being open and in some cases polysemic. The word “infinite” is used often in common speech and more frequently in literary language, but rarely with its precise meaning. In this way the concepts can be used in a vague way but an argument can still be structured so that the central idea is understood and is shared with to the partners. At the same time no precise definition is given to the concepts used and (...) each partner makes his own reading of the text based on previous experience and cultural background. In a language dictionary the first meaning of “infinite” agrees with the etymology: what has no end. We apply the word infinite most often and incorrectly as a synonym for “very large” or something that we do not perceive its completion. In this context, the infinite mentioned in dictionaries refers to the idea or notion of the “immeasurably large” although this is open to what the individual’s means by “immeasurably great.” Based on this linguistic imprecision, the authors present a non Cantorian theory of the potential and actual infinite. For this we have introduced a new concept: the homogon that is the whole set that does not fall within the definition of sets established by Cantor. (shrink)

This paper aims to enhance security in IoT device networks through a visual tool that utilizes three projection techniques, including Beta Hebbian Learning (BHL), t-distributed Stochastic Neighbor Embedding (t-SNE) and ISOMAP, in order to facilitate the identification of network attacks by human experts. This work research begins with the creation of a testing environment with IoT devices and web clients, simulating attacks over Message Queuing Telemetry Transport (MQTT) for recording all relevant traffic information. The unsupervised algorithms chosen provide a set (...) of projections that enable human experts to visually identify most attacks in real-time, making it a powerful tool that can be implemented in IoT environments easily.

A genuine commitment to ethics and compliance (E&C) programs means that top management adopt them for what they represent and not for other purposes. Only then can they truly build socially responsible behavior and a successful and sustainable business, as stated in the latest international standard for compliance management practice (ISO 37301:2021), which we found to be consistent with a new business narrative as conceptualized in Freeman's work. However, it also requires that top managers place a moral value on these (...) practices, rather than simply using them for instrumental reasons. Building on Kohlberg's six stages of moral development as applied to managers' moral thinking, this manuscript offers a model to explain how top managers' moral valuing of these practices varies along a moral reasoning continuum, resulting in four distinct modes. It also theorizes that each mode of moral valuing yields an archetype of E&C programs. It thus offers a new approach that contributes to the business ethics and management literature by incorporating a morally grounded perspective on the adoption and implementation of E&C practices and how it might shape their features and characteristics. It also aims to improve professional practice and business contributions to Freeman's ideas through genuine ethics‐based E&C programs. (shrink)

A dimensional reduction algorithm is applied to an intelligent classification model with the purpose of improving the efficiency and accuracy. The proposed classification model, used to distinguish the operating mode: Hard- and Soft-Switching, is presented and an analysis of the synchronized rectified step-down converter is done. With the aim of improving the accuracy and reducing the computational cost of the model, three different methods for dimensional reduction are applied to the input dataset of the model: self-organizing maps, principal component analysis (...) and correlation matrix. The obtained results show how the number of variable is highly reduced and the performance of the classification model is boosted: the results manifest an improve in the accuracy and efficiency of the classification.

As it is well known, mobile phones have become a basic gadget for any individual that usually stores sensitive information. This mainly motivates the increase in the number of attacks aimed at jeopardizing smartphones, being an extreme concern above all on Android OS, which is the most popular platform in the market. Consequently, a strong effort has been devoted for mitigating mentioned incidents in recent years, even though few researchers have addressed the application of visualization techniques for the analysis of (...) malware. Within this field, the present work proposes the extension of a new technique called Hybrid Unsupervised Exploratory Plots to visualize Android malware datasets. More precisely, the novel Beta-Hebbian Learning (BHL) method is applied for the first time and validated under the frame of Hybrid Unsupervised Exploratory Plots, in conjunction with clustering methods. The informative visualization achieved provides a picture of the structure of the malware families, allowing subsequent analysis of their organization. To validate the Hybrid Unsupervised Exploratory Plot extension and its tuning, the popular Android Malware Genome dataset has been used in the experimental setting. Promising results have been obtained, suggesting that BHL applied in combination with clustering techniques in Hybrid Unsupervised Exploratory Plots are a viable resource for the visualization of malware families.

This article studies the differences between traditional financial intermediaries (commercial banks, savings banks and cooperative banks) and ethical banks based on property rights, in which the owner decides the ideology, principles, standards and objectives of the organisation. In ethical banking, affinity centres on positive social and ethical values. The article consequendy focuses on an index proposed both to differentiate ethical banks from other types of banks, and also to pinpoint the differences between the various ethical banks themselves.This is the Radical (...) Affinity Index (RAI), which groups banks together in terms of their stance on ethical commitment, concentrating on ethical ideology and principles (information transparency, placement of assets, guarantees and participation) and using a sample of 114 European banks. The evidence shows that transparency of information and placement of assets are factors that differentiate ethical banks from other financial intermediaries.Guarantees and participation are characteristics specific to ethical banks; these variables, however, do not offer clear evidence to our analysis.

The present research describes a novel adaptive anomaly detection method to optimize the performance of nonlinear and time-varying systems. The proposal integrates a centroid-based approach with the real-time identification technique Recursive Least Squares. In order to find anomalies, the approach compares the present system dynamics with the average (centroid) of the dynamics found in earlier states for a given setpoint. The system labels the dynamics difference as an anomaly if it rises over a determinate threshold. To validate the proposal, two (...) different datasets obtained from a level control plant operation have been used, to which anomalies have been artificially added. The results shown have determined a satisfactory performance of the method, especially in those processes with low noise. (shrink)

The function and legitimacy of values in decision making is a critically important issue in the contemporary analysis of science. It is particularly relevant for some of the more application-oriented areas of science, specifically decision-oriented science in the field of regulation of technological risks. Our main objective in this paper is to assess the diversity of roles that non-cognitive values related to decision making can adopt in the kinds of scientific activity that underlie risk regulation. We start out, first, by (...) analyzing the issue of values with the help of a framework taken from the wider philosophical debate on science and values. Second, we study the principal conceptualizations used by scholars who have applied them to numerous case studies. Third, we appraise the links between those conceptualizations and learning processes in decision-oriented science. In this, we recur to the concept of methodological learning, i.e., learning about the best methodologies for generating knowledge that is useful for science-based regulatory decisions. The main result of our analysis is that non-cognitive values can contribute to methodological improvements in science in three principal ways: as basis for critical analysis, for contextualizing methodologies, and for establishing the burden of proof.

Batteries are a fundamental storage component due to its various applications in mobility, renewable energies and consumer electronics among others. Regardless of the battery typology, one key variable from a user’s perspective is the remaining energy in the battery. It is usually presented as the percentage of remaining energy compared to the total energy that can be stored and is labeled State Of Charge (SOC). This work addresses the development of a hybrid model based on a Lithium Iron Phosphate (LiFePO4) (...) power cell, due to its broad implementation. The proposed model calculates the SOC, by means of voltage and electric current as inputs and the latter as the output. Therefore, four models based on k-Means, Agglomerative Clustering, Gaussian Mixture and Spectral Clustering techniques have been tested in order to obtain an optimal solution. (shrink)

This paper based on the distinction between the instrumental and normative views of stakeholder management explores how business education and personal moral philosophies may influence the orientation adopted by an individual. A mediated regression analysis using survey information collected from 206 Spanish university students showed that those exposed to management theories were less willing to consider stakeholders when making business decisions if the consequent economic impacts on the firm were omitted. The results also provided support for a negative effect of (...) business education on idealism and a mediating effect of the latter on the relationship between education and stakeholder management orientation. This study thus raises awareness on the influence of business education on individuals’ ethical decision-making processes and suggests some possible changes for business education. (shrink)

In this research work a novel two-step system for anomaly detection is presented and tested over several real datasets. In the first step the novel Exploratory Projection Pursuit, Beta Hebbian Learning algorithm, is applied over each dataset, either to reduce the dimensionality of the original dataset or to face nonlinear datasets by generating a new subspace of the original dataset with lower, or even higher, dimensionality selecting the right activation function. Finally, in the second step Principal Component Analysis anomaly detection (...) is applied to the new subspace to detect the anomalies and improve its classification capabilities. This new approach has been tested over several different real datasets, in terms of number of variables, number of samples and number of anomalies. In almost all cases, the novel approach obtained better results in terms of area under the curve with similar standard deviation values. In case of computational cost, this improvement is only remarkable when complexity of the dataset in terms of number of variables is high. (shrink)

Elite athletes are characterized by their high level of performance in sport. Since the very beginnings of sport, it has been understood that physical and physiological abilities influence the performance of athletes. Advances in scientific knowledge, especially sport psychology and neuroscience, seem to confirm this intuition and consequently it is possible to characterize elite athletes as having an extraordinary combination of physical and mental abilities. Techniques and substances that contribute to enhancing physical characteristics of athletes have also been well known (...) for ages. But it is now possible to make use of other techniques and substances that not only enhance physical abilities but also cognitive capabilities, which seem to require greater consideration given their direct impact on the athlete’s brain. In this article, we examine two such techniques, cognitive enhancers and transcranial stimulators, and highlight the potential advantages and drawbacks that applying each one may have on sport. Given the relative novelty of these enhancement techniques and substances and the absence of conclusive evidence regarding their short- and long-term effects, we deem that their use ought to be strictly governed by cautionary principles. But due to that same lack of evidence, we believe that the possibility of examining the feasibility of applying these techniques to sport should not be denied. (shrink)

Manuscript type Empirical. Research question/issue This paper aims to contribute to an improved theoretical and empirical understanding of the role that corporation has to play in anticorruption efforts. Research findings/insights Using cross-country data from three databases (Bribe Payers Index, Corruption Perceptions Index, and Doing Business) we found that pro-bribery Investment Climate conditions in host countries are not related to the payments of bribes by multinational companies when these corporations operate abroad. Theoretical/academic implications After describing the conceptual and policy framework that (...) surrounds the discussion on the role played by firms in anticorruption, we present the current debate regarding the effectiveness of international bribery control instruments, with the World Bank-GAC (2006-2008) report as a basis. Both literature and policy seem to be divided into two main, although not mutually exclusive, positions: one demands improvements in Investment Climate conditions from a joint public-private consensus led by international agencies; the other one supports the effectiveness of self-regulation by firms, independent of Investment Climate improvements. The study provides empirical support to the idea that a better Investment Climate is not enough for reducing corrup tion. Practitioner/policy implications This study offers insights to policy makers interested in promoting the involvement of corporations in the fight against corruption. (shrink)

This article studies the observations which John Stuart Mill collected about Spain in his writings. The aim is to analyze how one of the most important thinkers of the time valued some political Spanish events, certain aspects of socioeconomic reality, or determined features which he considered to constitute the Spanish «national character». Throughout his entire intellectual trajectory, Mill seems to have been aware of the complex and eventful life of Spanish politics. Moreover, Mill visited Spain in 1860 and captured the (...) image of a country in a process of economic transformation, similar to the image portrayed by historians today and far from the romantic stereotypes that were so common to travel books of the 19th century.

sBuilding models as a practical aspect of ecological theory has as a principal purpose the determination of relations in formal language. In this paper, the authors provide a formalization of ecological models based on impure systems theory. Impure systems contain objects and subjects: subjects are human beings. We can distinguish a person as an observer that by definition is the subject himself and part of the system. In this case he acquires the category of object. Objects are significances, which are (...) the consequence of perceptual beliefs on the part of the subject about material or energetic objects with certain characteristics. The impure system approach is as follows: objects are perceptual significances of material or energetic objects. The set of these objects will form an impure set of the first order. The existing relations between these relative objects will be of two classes: transactions of matter and/or energy and inferential relations. Transactions can have alethic modality: necessity, possibility, impossibility and contingency. In this work we define measures which let us choose the more suitable variables to relate both the model with the ecosystem and with different models. In this way we define different comparison indexes. (shrink)

John Rawls shows a deep influence of David Hume’s thought, mainly at his Theory of Justice, though also at the rest of his works. This influence is well-known in the field of political philosophy, much less in the field of moral philosophy. Rawls reads Hume’s thought with a sceptic and naturalistic key, attributing him what he calls a “nature fideism”. Besides this, attributes to Hume an ethical and political position linked with the classical utilitarianism. Nevertheless, his skeptical epistemology will move (...) away, paradoxically, to Hume from the utilitarian positions. Hume’s ethics and politics will finish, according to Rawls, showing a purely descriptive character and a lack of normative purposes. Hume does not have in the strict sense a theory of practical reason. This article examines and puts in question this interpretation of Hume proposed by John Rawls. The philosophy of Hume is not aporetically skeptical, articulates the moral roles of reason and the passions; and finally, is not only connected with utilitarianism; his defense of the role of utility frees to his theory of some of the main contradictions of classical utilitarianism. Besides this, the theory of the “judicious spectator” can be considered a form of a theory of practical rationality. (shrink)

Commitment has been perceived as a strategic topic in organizations due to its positive effect on retaining talent, increasing performance, or boosting employees’ innovative behavior. However there are many focis of commitment in the workplace, which has represented a challenge to human resources management, who need implement measures to improve the employee’s commitment. Recent research has suggested a need to conduct studies about commitment, namely antecedents and the relationship between different focis, to understand the dynamic and directionality between them. Hence, (...) the purpose of this work is to analyze how employees’ emotional awareness relates with two focis of commitment, also assessing the mediating role of affective commitment to the leader. The study uses structural equation modeling and Lisrel to test the hypotheses considering the multidimensionality of organizational commitment, employees emotional awareness, and the affective commitment to the leader, under the scope of Social Exchange Theory. The Mackinon’s Z Test was used to assess the mediation role of affective commitment to the leader. The sample is composed for 403 employees from two multinational companies. The results provide empirical evidence about the mediating role of affective commitment to the leader in the relationship between employees’ emotional awareness and organizational commitment, and the employees’ emotional awareness as an antecedent of commitment. The implications for theory and practice are discussed. (shrink)

La crisis multidimensional por la que atraviesa actualmente la humanidad coloca en primer plano la cuestión, más que de «la salida de la crisis», de la superación de los condicionamientos negativos que han conducido a ella. Más allá de las causas próximas reconocibles se hallan las apuestas paradigmáticas, la Weltanschauung dominante que inspira las conductas erróneas. En el artículo se sostiene que a la metafísica materialista —que el autor distingue del ateísmo—, en tanto que idea-guía principal de la modernidad, corresponde (...) gran parte de la responsabilidad por las patologías de la sociedad actual, a cuyo clímax estamos asistiendo. Se asume que el mundo ha experimentado tales transformaciones que ninguna de las concepciones metafísicas o criptometafísicas a las que estamos acostumbrados sirve para fundamentar una guía de actuación capaz de sacarnos del atolladero. Y se propone una idea de fondo que se estima que sí podría hacerlo: un noocentrismo, la consideración de la consciencia como la realidad fundamental y, por supuesto, referencial. Un neoespiritualismo, si se quiere, capaz de fundamentar una Ética universal, y orientado a la liberación individual y colectiva del ser humano, en armonía con una Naturaleza entendida como de igual importancia, y dejando atrás el espejismo pseudocientífico —y en realidad sojuzgador y bloqueante— del materialismo metafísico.

Consider any subvariety of BL-algebras generated by a single BL-chain which is the ordinal sum of the standard MV-algebra on [0, 1] and a basic hoop H. We present a geometrical characterization of elements in the finitely generated free algebra of each of these subvarieties. In this characterization there is a clear insight of the role of the regular and dense elements of the generating chain. As an application, we analyze maximal and prime filters in the free algebra.

The liar paradox is a famous and ancient paradox related to logic and philosophy. It shows it is perfectly possible to construct sentences that are correct grammatically and semantically but that cannot be true or false in the traditional sense. In this paper the authors show four approaches to interpreting paradoxes that illustrate the influence of: the levels of language, their belonging to indeterminate compatible propositions or indeterminate propositions, being based on universal antinomy and the theory of dialetheism.
