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)

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)

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)

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.

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.

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)

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)

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.

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)

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.

El texto define cada posición según sus potencialidades y límites para sobrevivir en el campo de la Filosofía. En diálogo con el libro de Francisco Vázquez intenta comprender qué permaneció y qué cambió en la filosofía española.

The quantization of the magnetic flux in superconducting rings is studied in the frame of a topological model of electromagnetism that gives a topological formulation of electric charge quantization. It turns out that the model also embodies a topological mechanism for the quantization of the magnetic flux with the same relation between the fundamental units of magnetic charge and flux as there is between the Dirac monopole and the fluxoid.

Fundamental records of Post-Husserlian Philosophy are highlighted by Sein und Zeit, Lʼêtre et le néant and the Phénoménologie de la perception, the work by Merleau-Ponty that deals with the problem of intersubjectvity, starting from a very particular concept of the body understood as «a work of art». However, the reasoning developed in his work of 1945 is about the sociopolitical dimensions of present intersubjectivity. This article carries out the analysis of later works by Merleau-Ponty, in which he studies the relationship (...) between Perception and everyday life to continue with the consideration of the aesthetic and pictorial sphere in order to develop a theory of Vision that has to be understood as a complement to the theory of Perception. This theory would be the ground to transcend the contingency and locate the relationship present-past as the final step of the theory of Intersubjectivity. (shrink)

Engagement of integrins and other adhesion receptors can induce tyrosine phosphorylation of focal adhesion kinase (FAK), a tyrosine kinase present in focal adhesions. Furthermore, in addition to adhesion receptors, a surprising variety of stimuli, acting either on specific surface receptors or on intracellular molecules, such as PKC or Rho, can induce also tyrosine phosphorylation of FAK. I suggest that a potential mechanism by which such distinct factors may modulate the tyrosine phosphorylation of FAK is the promotion of integrin or other (...) adhesion receptor clustering at focal adhesions.
