Over the last few years, a new methodology to address the P versus NP problem has been developed, based on searching for borderlines between the nonefficiency of computing models and the presumed efficiency. These borderlines can be seen as frontiers of efficiency, which are crucial in this methodology. “Translating,” in some sense, an efficient solution in a presumably efficient model to an efficient solution in a nonefficient model would give an affirmative answer to problem P versus NP. In the framework (...) of Membrane Computing, the key of this approach is to detect the syntactic or semantic ingredients that are needed to pass from a nonefficient class of membrane systems to a presumably efficient one. This paper deals with tissue P systems with communication rules of type symport/antiport allowing the evolution of the objects triggering the rules. In previous works, frontiers of efficiency were found in these kinds of membrane systems both with division rules and with separation rules. However, since they were not optimal, it is interesting to refine these frontiers. In this work, optimal frontiers of the efficiency are obtained in terms of the total number of objects involved in the communication rules used for that kind of membrane systems. These optimizations could be easier to translate, if possible, to efficient solutions in a nonefficient model. (shrink)

Balancing Change and Tradition in Global Education Reform is an invaluable resource for policymakers, faculty, students, and anyone interested in how decisions made about the education system ultimately affect the quality of education, educational access, and social justice.

Higher education in the 21st century faces the challenge of changing the way in which knowledge is conveyed and how teachers and students interact in the teaching-learning process. The current pandemic caused by SARS-CoV-2 has hastened the need to face up to this challenge and has furthered the need to approach the issue from the perspective of digitalisation. To achieve this, it is necessary to design training programmes geared towards teaching staff and which address both the use of technology and (...) instructional design aimed at promoting the development of self-regulated learning and automatic feedback systems. In this study, work was carried out with 23 teachers in a training programme conducted through Moodle. The aims were: to test whether there were any significant differences between the behaviour patterns of new teachers compared to experienced teachers, to determine whether clusters of behaviour patterns corresponded to the type of teacher and to ascertain whether the level of teacher satisfaction with the training activity in digital teaching will depend on the type of teacher. A quantitative as well as a qualitative design was applied. Differences were found in the behaviour patterns in the training activities for the development of rubrics and use of learning analytics systems in virtual learning environments. It was also found that the type of teacher did not correspond exactly to the behaviour cluster in the learning platform. In addition, no significant differences were found in the level of satisfaction between the two kinds of teacher. The main contribution this study makes is to provide a detailed description of the training stage as well as the materials required for its repetition. Further analytical studies are required on teacher perception of training programmes in digital teaching in order to provide personalised training proposals that lead to an effective use of teaching in digital environments.

IntroductionCognitive impairment is a highly prevalent non-motor feature of Parkinson’s disease. A better understanding of the underlying pathophysiology may help in identifying therapeutic targets to prevent or treat dementia. This study sought to identify metabolic alterations in the prefrontal cortex, a key region for cognitive functioning that has been implicated in cognitive dysfunction in PD.MethodsProton Magnetic Resonance Spectroscopy was used to investigate metabolic changes in the PFC of a cohort of cognitively normal individuals without PD, as well as PD participants (...) with either normal cognition, mild cognitive impairment, or dementia. Ratios to Creatine resonance were obtained for glutamate, glutamine and glutamate combined, N-acetylaspartate, myoinositol, and total choline, and correlated with cognitive scores across multiple domains administered to the PD participants only.ResultsWhen individuals retain cognitive capabilities, the presence of Parkinson’s disease does not create metabolic disturbances in the PFC. However, when cognitive symptoms are present, PFC Glu/Cre ratios decrease with significant differences between the PD-NC and PPD groups. In addition, Glu/Cre ratios and memory scores were marginally associated, but not after Bonferroni correction.ConclusionThese preliminary findings indicate that fluctuations in prefrontal glutamate may constitute a biomarker for the progression of cognitive impairments in PD. We caution for larger MRS investigations of carefully defined PD groups. (shrink)

The article deals with the constitution of a «historical people» in the conference munity that underlie to the interpretations of works of art in the conference are examined, pointing out the relationship of both with two types of different communities. In turn, they also constituted the images of ideal community of nacionalsocialism in power. This coincidence shows a deep agreement of Heidegger with governing nacionalsocialism different from a mere adhesion to the party. In this way, it is shown the parallel (...) of the question about the «new beginning» looked for by Heidegger starting from the Kehre and his political commitment for those years. (shrink)

The Sourcebook is a thematically unified collection of seminal texts in the history of economics on the topic of money and exchange relations —its nature, purpose, value, and relationship to justice and morality in financial transactions—within the tradition of late-scholastic commercial ethics.

Résumé Le refus par Arnauld, en 1641, de la thèse cartésienne d’une fausseté des idées, et non des seuls jugements, est habituellement analysé en fonction de l’admission, vue comme un revirement sous l’influence des Quatrièmes réponses, des idées de la sensation comme idées fausses dans la Logique. J’essaie au contraire de rapporter ce refus seulement aux textes des Méditations et des Premières réponses qui lui servent d’appui. Arnauld construit son objection en sorte que la thèse des idées fausses apparaisse en (...) contradiction avec la doctrine cartésienne même des idées. Ce n’est nullement la fausseté des idées de la sensation, mais la fausseté des idées tout court, qui est sa cible, et ses écrits ultérieurs manifestent une forme de continuité avec les raisons de sa critique initiale, plutôt qu’un simple abandon de cette dernière.

Many years before Adam Smith, numerous theologians associated with the School of Salamanca, such as Domingo de Soto, Juan de Lugo, Juan de Mariana, Luís Saravia de la Calle, Martin de Azpilcueta, Luis de Molina, Leonard Lessius, Thomas Cajetan, and Francisco Garcia had made great strides in the development of economics. Specifically, these theologians, otherwise known as the “Scholastics,” analyzed and argued against price and wage controls by explaining that the only “just” prices and wages are those that are (...) set by the market, examined and pushed back against prohibitions on usury, understood the concept of time preference, and helped develop monetary theory in multiple ways. They also demonstrated that all of this was consistent with the Catholic religion. This paper analyzes the ways in which these early theologians contributed to the development of economics and reconciled it with their Catholicism. (shrink)

The focus of this article is on representations of irregular migration in a Scandinavian context and how irregular migrants are constructed as a target group. A common feature in many European states is the difficult attempt to navigate between an urge for control and respecting, upholding and promoting humanitarian aspects of migration management. Legitimizing policies therefore become extremely important as governments have to appease national voters to remain in power and have to respect European regulations and international conventions. Doing so (...) raises questions of social, political and economic rights, of moral obligations, of sovereignty, and of equity, as well as of how to define target groups and legal and categorical statuses into the debates. Having a backdrop in the theoretical framework of Carol Bacchi, Anne Schneider and Helen Ingram and Giorgio Agamben, this article looks at how policy problematizations and constructions of target populations guide and legitimize particular policy approaches and may end up marginalizing and excluding groups in society and ultimately become a challenge for democracy.Dansk abstract: Legitimering af politik: Hvordan politiske tilgange til irregulære indvandrere formuleres og legitimeres i SkandinavienFokus i denne artikel er på repræsentationer af irregulær migration i en skandinavisk kontekst og hvordan illegale indvandrere er konstrueret som målgruppe. Et fælles træk i mange vesteuropæiske nationalstater er det svære forsøg på at navigere mellem kontrol og samtidig respektere, forsvare og fremme humanitære aspekter af migrationsstyringen. At legitimere den givne politik er derfor blevet særdeles vigtigt fordi regeringerne er nødt til at formilde de nationale indvandringsskeptiske vælgere for at forblive ved magten og er nødsaget til at respektere europæiske regler og internationale konventioner. Dette italesætter en diskussion om sociale, politiske og økonomiske rettigheder, af moralske forpligtelser, af suverænitet, af at definere målgrupper og juridiske statuskategorier i debatterne. Artiklen har baggrund i en teoretisk ramme som er udstukket af Carol Bacchi, Anne Schneider, Helen Ingram og Giorgio Agamben. Artiklen ser på, hvordan politiske problematiseringer og konstruktioner af målgrupper vejleder og legitimerer bestemte politiske strategier og kan ende med at marginalisere og udelukke grupper i samfundet og i sidste ende blive en udfordring for demokratiske principper som sådan.

Today's sweatshops violate our notions of justice, yet they continue to flourish. This is so because we have not settled on criteria that would allow us to condemn and do away with them and because the poor working conditions in certain places are preferable to the alternative of no job at all. In this paper, we examine these phenomena. We consider the definitional dilemmas posed by sweatshops by routing a standard definition of sweatshops through the precepts put forward in the (...) literature on justice and virtue ethics. We conclude that fixing on definitions is pointless and misleading and that we are better off looking at whether or not a workplace violates the basic human rights of workers and whether or not the working conditions there cohere with situations on which we have already rendered judgments. In the end, we suggest guidelines for businesses that operate in the global workplace to help them avoid charges of running sweatshops. These recommendations account for the harsh living conditions in certain developing and emerging countries as well as the norms of societies in developed countries. (shrink)

Experiments using a modified gap paradigm, where regular trials are intermingled with catch trials, demonstrate that the relative frequency of express versus regular saccades distinctly depends on catch trial frequency. More specifically, it has been shown that the probability of an express saccade depends stochastically on the type of the preceding trial, that is, on the sequence of stimuli. We discuss whether such contextual effects can be accommodated within the framework of Findlay & Walker's model.

Natural language processing involves a tight coupling between action (the production of language) and perception (the comprehension of language). We argue that similar theoretical principles apply to language processing as to action/perception in general. Language production is not driven solely by the speaker's intentions; language comprehension is not only input-driven; production and perception use common representations. We will relate recent findings from our language production lab to the Theory of Event Coding (TEC)'s principle of feature binding.

William of Ockham is often thought to be the medieval progenitor of divine command theory. This paper contends that the origin of a thoroughgoing and fully reductive DCT position is perhaps more appropriately laid at the feet of Andrew of Neufchateau. We begin with a brief recapitulation of an interpretive dispute surrounding Ockham in order to highlight how there is enough ambiguity in his work about the metaphysical foundations of morality to warrant suspicion about whether he actually stands at the (...) origin of DCT. We then show how all such ambiguity is jettisoned in the work of Andrew, who explicitly rejects a position similar to one plausibly attributable to Ockham and also articulates a fully reductive DCT.

This study draws upon the behavioral agency model and the concept of socioemotional wealth to investigate how family firms’ employee pension underfunding decisions differ from those of non-family firms. We explore how these differences are influenced by financial distress, generational stage, and whether the firm is eponymous. We test our hypotheses using data from 452 US firms over an eleven-year period. Our results suggest that family firms are less likely to underfund pensions, but this effect is attenuated in later generational (...) ownership stages and in non-eponymous firms. (shrink)

This study investigated whether temporal clustering of autobiographical memories around periods of self-development would also occur when imagining future events associated with the self. Participants completed an AM task and future thinking task. In both tasks, memories and future events were cued using participant-generated identity statements . Participants then dated their memories and future events, and finally gave an age at which each identity statement was judged to emerge. Dates of memories and future events were recoded as temporal distance from (...) the identity statement used to cue them. AMs and future events both clustered robustly around periods of self-development, indicating the powerful organisational effect of the self. We suggest that life narrative structures are used to organise future events as well as memories. (shrink)

We reply to Christoph Jäger's criticism of the conditional probability solution (CPS) to the value problem for reliabilism due to Goldman and Olsson (2009). We argue that while Jäger raises some legitimate concerns about the compatibility of CPS with externalist epistemology, his objections do not in the end reduce the plausibility of that solution.

This paper retraces some of the contrast between Aquinas and Scotus with respect to the metaphysical foundations of morality in order to highlight how subtle differences pertaining to the relationship between the divine will and the divine intellect can tip a thinker toward either an unalloyed natural law theory (NLT) or something that at least starts to move in the direction of divine command theory (DCT). The paper opens with a brief consideration of three distinct elements in Aquinas’s work that (...) might tempt one to view him in a DCT light, namely: his discussion of the divine law in addition to the natural law; his position on the so-called immoralities of the patriarchs; and some of his assertions about the divine will in relation to justice. We then respond to each of those considerations. In the second and third of these cases, following Craig Boyd, we illustrate how Aquinas’s conviction that the divine will follows the ordering of the divine intellect can help inform the interpretive disputes in question. We then turn our attention to Scotus’s concern about the freedom of the divine will, before turning to his discussion of the natural law in relation to the Decalogue as a way of stressing how his two-source theory of the metaphysical foundations of morality represents a clear departure from Aquinas in the direction of DCT.

This article deals with a mosaic from ancient Zeugma on the Euphrates found in 2002 and recently published with interpretive commentary. Its subject is the story of Theonoe and Leukippe preserved only in Hyginus and nowhere in Greek. Despite this, the authors argue that the myth, in its unique form, can for over one thousand years be connected with romance, mime, pantomime, tragedy and derives ultimately from early Cretan rituals of transvestism. Its immediate inspiration however is imperial pantomime along with (...) the transvestism notorious in that genre, as can be argued from the layout of the mosaic and the iconography of Theonoe, our first clear picture of a pantomime. But the main thrust of the article, especially in appendix B, is to demonstrate that the Hyginus story must now be considered to represent the plot of a lost tragedy, which derived many of its elements from late Euripides, but in its over-enthusiasic use of these represents a post-Euripidean artificially complex plot-type, for which hitherto we had limited evidence.

The aim of our research is to analyze how different religions influence business ethics. We develop an index of practices in the field of business ethics, made up of 19 items containing practices related to workers, consumers, products, human rights, management of ethical conflicts, and crime prevention. Also, we consider a wide range of religion affiliations. To undertake this research, we use a panel data sample composed of 11,956 firm‐year observations from 18 countries. Drawing on stakeholder theory, we posit some (...) hypotheses based on the religions considered. The results obtained show that a higher percentage of religious adherents in the country where a company does business usually involve the implementation of more ethical practices in the corporate field. These findings are obtained for Christian, Islamic, Jewish, and Hindu religions. In contrast, this does not stand for Buddhist and folk religions. Also, countries where there is no predominant religion do not show a confluence between religion and ethical corporate practices. (shrink)

Grime (1979) in a recently developed theory distinguished three basic plant strategies: stress tolerance,ruderality and competition. He relates them to environments characterized in terms of stress and disturbance. Classifications of strategies and environments both are ultimately defined in terms of production. This tends to make the theory tautological. If the theory is to make sense, environments had better be defined in independent terms.
