The variety DMM of De Morgan monoids has just four minimal subvarieties. The join-irreducible covers of these atoms in the subvariety lattice of DMM are investigated. One of the two atoms consisting of idempotent algebras has no such cover; the other has just one. The remaining two atoms lack nontrivial idempotent members. They are generated, respectively, by 4-element De Morgan monoids C4 and D4, where C4 is the only nontrivial 0-generated algebra onto which finitely subdirectly irreducible De Morgan monoids may (...) be mapped by noninjective homomorphisms. The homomorphic preimages of C4 within DMM constitute a proper quasivariety, which is shown to have a largest subvariety U. The covers of the variety within U are revealed here. There are just ten of them. In exactly six of these ten varieties, all nontrivial members have C4 as a retract. In the varietal join of those six classes, every subquasivariety is a variety—in fact, every finite subdirectly irreducible algebra is projective. Beyond U, all covers of [or of ] within DMM are discriminator varieties. Of these, we identify infinitely many that are finitely generated, and some that are not. We also prove that there are just 68 minimal quasivarieties of De Morgan monoids. (shrink)

The debate on the influence of markets on virtues has focused on two opposite hypotheses: the doux commerce thesis and the self-destruction thesis. Whereas the doux commerce hypothesis assumes that capitalism polishes human manners, the self-destruction hypothesis holds that capitalism erodes the moral foundation of society. This paper will develop a more balanced position by using the virtue ethics developed by Aristotle, which distinguishes several virtues. The research will focus on the question for which virtues the doux commerce or self-destruction (...) thesis is likely to hold. An extensive literature survey shows that market competition tends to stimulate diligence, crowd out temperance, generosity, and sociability, and stimulate envy. The effect on other virtues – i.e. courage, high-spiritedness, justice, and prudence – is ambiguous. (shrink)

This article engages various critiques of Fair Trade, from its participation in commodification to providing a cover for "Fair-washing" corporations, and argues that Fair Trade has the potential to answer the challenges contained within them if and when it initiates an ongoing process of developing the "ethical valuedadded" content of the label. This argument is made in a number of ways. First, by distinguishing between economic and human development impacts and ethics, this article argues that these impacts are necessary but (...) not sufficient conditions for ethical trade. Second, it engages the question of the possibility of ethical practice in economics generally; developing the idea that when economics is concerned with securing the material basis of a broad range of life capacities it becomes ethical. Third, Fair Trade practice itself is examined from this standpoint, and is conceived of as both comprising a promising ethical value-added practice as well as posing a problem in its current formulation that the framework of ethical valueadded can help understand and resolve. Finally, an examination of these theoretical ideas in practice is undertaken through a case study of Café Femenino, a Fair Trade coffee produced in Peru. In conclusion it is argued that for Fair Trade to build upon its economic and human impacts, and therefore remain a meaningful ethical and economic alternative to corporate capitalism and globalization, it must distinguish itself clearly in ethics from those market relations it wishes, explicitly or implicitly, to challenge.

In an earlier paper I argued that time travellers cannot change the past: alleged models of changing the past either fall into contradiction or else involve avoiding, not changing, the past. Goddu has responded to my argument, maintaining that his hypertime model involves time travellers changing (not avoiding) the past. In the present paper I first discuss what would be required to substantiate the claim that a given model involves changing rather than avoiding the past. I then consider Goddu's hypertime (...) model and an earlier model due to Meiland. I argue that neither author does what would be required to substantiate the claim that the model involves changing (not avoiding) the past. I go on to give reasons for the stronger claim that no-one can present a coherent model and also substantiate the claim that it involves changing (not avoiding) the past. (shrink)

Het Leids-Haags Allegorieënlexicon toont nieuwe perspectieven op de maatschappelijke werkelijkheid met een actuele duiding van vijftig kernthema’s uit de wetenschap. De auteurs zijn de duale promovendi en hun promotores van Leiden University Dual PhD Centre The Hague. Ze worden daarbij geïnspireerd door de metafoor van de grot van Plato: Waar ben ik? Waar sta ik? Welk beeld zie ik? Hoe kan ik dat begrijpen? Er ontstaan beeldende voorstellingen van begrippen waarin op zoek wordt gegaan naar de centrale gedachten die ten (...) grondslag liggen aan die begrippen. Zo wordt de veranderende wereld waargenomen met het besef dat we nooit kunnen weten of we de gehele werkelijkheid kunnen zien of begrijpen. De waarneming is afhankelijk van de zichtpositie die de waarnemer inneemt. Zo ontstaan verbeeldingen van waarnemingen van ons menselijk bestaan. Zoals: assimilatie, creativiteit, gender, kunstenaarschap, magistraat, participatie, regels, tragedie en verzorgingsstaat. Eerst wordt actuele literatuur besproken. Daarna volgt discussie. Tenslotte neemt de auteur positie in. Met bijdragen van promotores Wilfried Admiraal, Ingrid van Biezen, Hans Borgman, Paul Cliteur, Jaap van den Herik, Rikki Holtmaat, Willem Otterspeer, Jos Raadschelders, Robert Tijssen, Wim Willems en promovendi.

We analyse the relationship between applicability and effectiveness of legal norms from a philosophical perspective. In particular, we distinguish between two concepts of applicability. The external applicability of norms refers to institutional duties; a norm N is externally applicable if and only if a judge is legally obliged to apply N to some case c. Internal applicability refers instead to the sphere of validity of legal norms. A norm N is internally applicable to actions regulated by its sphere of validity. (...) We also explore the consequences of a thesis which maintains that applicability restricts the concept of effectiveness, so that only applicable norms can be considered effective. Our analysis illustrates that a proper reconstruction of the concept of applicability is of great importance not only for understanding the concept of effectiveness but also for providing insight into the nature of law.

A superconducting transition temperature as high as 100 K was recently discovered in one monolayer FeSe grown on SrTiO3. The discovery ignited efforts to identify the mechanism for the markedly enhanced Tc from its bulk value of 8 K. There are two main views about the origin of the Tc enhancement: interfacial effects and/or excess electrons with strong electron correlation. Here, we report the observation of superconductivity below 20 K in surface electron-doped bulk FeSe. The doped surface layer possesses all (...) the key spectroscopic aspects of the monolayer FeSe on SrTiO3. Without interfacial effects, the surface layer state has a moderate Tc of 20 K with a smaller gap opening of 4.2 meV. Our results show that excess electrons with strong correlation cannot induce the maximum Tc, which in turn reveals the need for interfacial effects to achieve the highest Tc in one monolayer FeSe on SrTiO3.

There have been two main lines in the literature on restricted games: the first line was started by Myerson (1977) that studied graph-restricted games an the second one was initiated by Faigle (1989). The present paper provides a unified way to look on the literature and establishes connections between the two different lines on restricted games. The strength and advantages of this unified approach becomes clear in the study of the inheritance of the convexity from the game to the restricted (...) game where an interesting result by Nouweland and Borm (1991) on the convexity of graph-restricted games is turned into a direct consequence of the corresponding result by Faigle (1989), by means of this relation.

Der Atheismus erlebte in den letzten Jahren eine Renaissance. Durch verschiedene Publikationen wurde der Atheismus in der Offentlichkeit und in den Wissenschaften wieder zum Thema. Religioser Glaube sei mit einem wissenschaftlichen Weltbild nicht vereinbar, so viele Atheisten. Diese Bewegung fasst man unter dem Namen Neuer Atheismus zusammen. Aber ist tatsachlich etwas neu am neuen Atheismus? Gibt es in den modernen Naturwissenschaften noch einen Platz fur Gott? Konnen Argumente der neuen Atheisten uberzeugend zeigen, dass es unvernunftig und unwissenschaftlich ist, an die (...) Existenz eines Gottes zu glauben? Dies sind nur einige Beispielfragen, die die Autoren dieses Bandes versuchen werden zu beantworten. Die Autoren kommen aus unterschiedlichsten Disziplinen: Aus der Physik, der Biologie, der Mathematik, der Philosophie und der Theologie.". (shrink)

Le névrosé est un homme qui demeure infantile et s'enferme dans un refuge imaginaire. Sans courage, il est prisonnier des angoisses primitives. A partir d'une compréhension de la relation fondamentale entre l'angoisse et le courage s'éclaire la valeur proprement humaine de l'amour humain, de la rencontre, de la confrontation et de la liaison entre le Moi et le Toi comme une existence sous la forme du Nous - la „liebende Wirheit” dont parle Binswanger. Le mysterium tremendum de l'amour personnel pour (...) un ‘étranger’ - qui n'est donc n i la mère n i le père - est un risque existentiel par essence, c'est le franchissement du seuil vers une forme nouvelle de l'existence du Dasein. C'est la raison pour laquelle la route vers le Toi passe par l'angoisse et que l'engagement dans cette voie présuppose un Moi libre, courageux et responsable. C'est ce que nous apprend déjà le dicton : „Qui veut épouser la fille du roi doit d'abord supporter le tremblement de l'angoisse”. Le courage qui est ici nécessaire s'accomplit dans la liberté heureuse de ce qu'on a appelé le „discours-révélant” -par lequel le „langage-du-désir” de notre inconscience originelle est assumé et qu'il accomplit sa signification.

There are five main claims that may be made about life after death: We are reincarnated in the self-same body we had in life. We are reincarnated in another body. We are revived, or continue to live in a disembodied form.
