A continuoxis t- norm is a continuous map * from [0, 1]² into [0,1] such that is a commutative totally ordered monoid. Since the natural ordering on [0,1] is a complete lattice ordering, each continuous t-norm induces naturally a residuation → and becomes a commutative naturally ordered residuated monoid, also called a hoop. The variety of basic hoops is precisely the variety generated by all algebras, where * is a continuous t-norm. In this paper we investigate the structure of the (...) variety of basic hoops and some of its subvarieties. In particular we provide a complete description of the finite subdirectly irreducible basic hoops, and we show that the variety of basic hoops is generated as a quasivariety by its finite algebras. We extend these results to Hájek's BL-algebras, and we give an alternative proof of the fact that the variety of BL-algebras is generated by all algebras arising from continuous t-norms on [ 0,1] and their residua. The last part of the paper is devoted to the investigation of the subreducts of BL- algebras, of Gödel algebras and of product algebras. (shrink)

We develop and apply a multi-dimensional conception of explanatory depth towards a comparative analysis of inflationary and bouncing paradigms in primordial cosmology. Our analysis builds on earlier work due to Azhar and Loeb (2021) that establishes initial condition fine-tuning as a dimension of explanatory depth relevant to debates in contemporary cosmology. We propose dynamical fine-tuning and autonomy as two further dimensions of depth in the context of problems with instability and trans-Planckian modes that afflict bouncing and inflationary approaches respectively. In (...) the context of the latter issue, we argue that the recently formulated trans-Planckian censorship conjecture leads to a trade-off for inflationary models between dynamical fine-tuning and autonomy. We conclude with the suggestion that explanatory preference with regard to the different dimensions of depth is best understood in terms of differing attitudes towards heuristics for future model building.

Distributive, procedural, and interactional justice are constructs that are increasingly being recognized as important factors that affect individual perceptions in the workplace environment. This paper presents a theoretical perspective that suggests that justice is perceived through a subjective lens that consists of individualized beliefs and proposes that cultural attributes and demographic characteristics play an integral part in determining the perception of justice. The distinctions between these three constructs are presented in context with the core beliefs of individual employees – affected (...) by a multitude of perceptual and demographic factors that we briefly identify herein. Based on the theoretical perspective, an instrument that measures the constructs of justice as perceived by individuals was developed. With a focus on justice within the business setting, hypotheses about attitudes related to justice were tested. Survey results confirm that the three constructs of justice are distinct but correlated. Significant differences were found in the perceptions of African-American respondents with regard to procedural justice. Although the empirical findings do not support all the hypotheses, this research highlights the need for further development of measures to assess the perception of justice in business settings and at an applied level, underscores the importance of recognizing cultural attributes and demographic characteristics in understanding how justice is perceived.

When I offered this title, I was engaging myself to investigate an apparent difference between two kinds of intentionality, in the hope that I should be able to find some firm logical criterion to distinguish them. I was less successful in this than I had hoped. I think I have gained a certain amount of insight into the logic and semantics of one kind of intentional context, largely due to the work I was doing while visiting the University of Pennsylvania (...) on Frege and on Michael Dummett’s monumental commentary on Frege. But as regards the other variety of intentionality I am still very much in the dark; so I am giving you thus far merely a progress report on that. (shrink)

In this essay, P. Taylor Webb and Kalervo N. Gulson argue that educational policy is a spatial process and that implementation processes in particular produce crucial emergent geographies for policy research. Webb and Gulson describe how emergent geographies are produced when policy folds actors through senses and enactments of policy. The idea that policy is sensed and enacted is developed into the concept of a policy intension that extends approaches to spatial and, in particular, micropolitical analyses in policy research. Webb (...) and Gulson conclude by discussing cartographical methods that better map the geographies of subjectivity produced through policy intensions. (shrink)

The conception of “prospective potency” was defined by its author H.Driesch as “the sum of the possible modes of development of a given part of the embryo”. However, in the language of science the word “potency” usually means “power”, not “possibility”. Therefore this conception from the beginning possessed a certain ambiguity, that it retained up to the present. The distinction of “active” and “passive” potency, introduced by Roux, has found no general acceptance. It appeared necessary to submit the conception of (...) “potency” to a profound analysis. In the first place it is shown, that the ambiguity of this conception vanishes, if we understand by the word “potency” those fundamental properties of the embryonic material, that are responsible for its various developmental possibilities. We can distinguish among these properties the “reactive powers”, by which the embryonic material reacts to inductive stimulations, and its own “developmental tendencies”. These faculties only differ by their strength; a “reactive power” may change into a “tendency”, when its intensity increases during development; conversely, a “tendency” may change into a mere “reactive power” by a decrease of its strength. The determination of the material results from the conflict of its tendencies. The inductive actions interfere by strengthening or weakening different tendencies, and by activating new tendencies by reinforcement of the “reactive powers” of the embryonic material.La conception de „prospektive Potenz” fut définie par son auteur H.Driesch comme „l'ensemble des modes de développement possibles d'une certaine partie de l'embryon”. Cependant, le, mot „Potenz” dans le langage de la science répond plutôt à la „puissance” qu'à la „possibilité”. De là résulte, que cette conception dès son origine avait une certaine ambiguïté, qui se fait sentir jusqu'à présent. La distinction entre „potentialité active” et „potentialité passive”, proposée par Roux, n'est pas acceptée généralement. Il se trouvait nécessaire, que la conception de „Potenz” fût soumise à une. analyse profonde. D'abord il est démontré, que l'ambiguïté de cette conception disparaît, si on entend par le mot „Potenz” les propriétés fondamentales du matériel embryonnaire, qui sont à la base de ses diverses possibilités de développement. On peut distinguer parmi ces propriétés les „pouvoirs réactifs”, en vertu desquels le matériel embryonnaire répond à des inductions morphogénétiques, et les „tendances propres” du matériel. Ils ne diffèrent que par leur intensité; un „pouvoir réactif” peut se changer en „tendance” par suite d'un renforcement au cours du développement, une „tendance” peut se changer en „pouvoir réactif” par une diminution d'intensité. La détermination du matériel se réalise par une „lutte” entre les tendances. Les actions inductives influent sur cette lutte en renforçant ou en diminuant l'intensité des diverses tendances, et en activant de nouvelles tendances par le renforcement de „pouvoirs réactifs”.

In this desolate ancient country, which is a semicolony, all activities [seemed to have] stopped. People's lives have also become meaningless. The warm breeze blown from other countries stirred the curiosity of youth. Go! Let us go to the free world. And so, many people left the motherland for France in Europe, as if even workers there were happier than gentlemen here. But what was the reality? They were unable to do very hard work like the average workers. So their (...) idealized country became the target of their curses. (shrink)
