Relations and relational operators can be used to define the semantics of programming languages. The operations∨and∘serve to giveangelic semanticsby defining a program to go right when there is a possibility to go right. On the other hand, the demonic operations⊔and□do the opposite: if there is a possibility to go wrong, a program whose semantics is given by these operators will go wrong; it is thedemonic semantics. This type of semantics is known at least since Dijkstra's introduction of the language of guarded commands. Recently, there has been a growing interest in demonic relational semantics of sequential programs. Usually, a construct is given an ad hoc semantic definition based on an intuitive understanding of its behavior. In this note, we show how the notion ofrelational flow diagram(essentially a matrix whose entries are relations on the set of states of the program), introduced by Schmidt, can be used to give a single demonic definition for a wide range of programming constructs. This research had originally been carried out by J. Desharnais and F. Tchier (1996) in the same framework of the binary homogeneous relations. We show that all the results can be generalized by using the monotypes and the residuals introduced by Desharnais et al. (2000).

Hawthorne (2001) toys with the view that ascriptions of free will are context-sensitive. But the way he formulates the view makes freedom contextualism look like a non-starter. I step into the breach for freedom contextualism. My aim is twofold. On the one hand, I argue that freedom contextualism can be motivated on the basis of our ordinary practice of freedom attribution is not ad hoc. The view explains data which cannot be accounted for by an ambiguity hypothesis. On the other hand, I suggest a more plausible freedom contextualist analysis, which emerges naturally once we pair the assumption that freedom requires that the agent could have acted otherwise with a plausible semantics of "can" statements. I'll dub the resulting view Alternate Possibilities Contextualism, or APC, for short. In contrast to Hawthorne's view, APC is well-motivated in its own right, does not beg the question against the incompatibilist and delivers a context parameter which allows for a wide range of context shifts. I conclude that, far from being a non-starter, freedom contextualism sets an agenda worth pursuing.


to increase simultaneously the manifestness of a wide range of assumptions, so that her intention concerning each of these assumptions is weakly manifest, then each of them is weakly communicated. An example would be sniffing ecstatically and osten-sively at the fresh seaside air. There is, of course, a continuum of cases in between. In the case of strong communication, the communicator can have fairly precise expectations about some of the thoughts that the audience will actually entertain. With weaker forms of communication, the communicator can merely expect to steer the thoughts of the audience in a certain direction. Often, in human interaction, weak communication is found sufficient or even preferable to the stronger forms. Non-verbal communication tends to be relatively weak. One of the advantages of verbal communication is that it gives rise to the strongest possible form of com-munication; it enables the hearer to pin down the speaker’s intentions about the explicit content of her utterance to a single, strongly manifest candidate, with no alternative worth considering at all. On the other hand, what is implicit in ver-bal communication is generally weakly communicated: the hearer can often fulfil part of the speaker’s informative intention by forming any of several roughly similar but not identical assumptions. Because all communication has been seen as strong communication, descriptions of non-verbal communication have been marred by spurious attributions of ‘meaning’; in the case of verbal communication, the difference between explicit content and implicit import has been seen as a differ-ence not in what gets communicated but merely in the means by which it is com-municated, and the vagueness of implicatures and non-literal forms of expression has been idealised away. Our account of informative intentions in terms of man-ifestness of assumptions corrects these distortions without introducing either ad hoc machinery or vagueness of description.

In recent years, much research has been devoted to the refinement of IPv6; on the other hand, few have investigated the confusing unification of interrupts and Internet QoS. In this position paper, it demonstrates the emulation of interrupts. In order to overcome this quagmire, a novel system is presented for the intuitive unification of expert systems and massive multiplayer online role-playing games. It is concluded that erasure coding can be verified to make heterogeneous, interposable, and event-driven, which is proved to be applicable.

The behaviour of various types of polar dienes towards halogenated ortho quinones has been investigated in a number of representative cases. As compared to the commonly used para analogues, o-quinones provide a wide range of products that indicate a keener response to the nature, number, and position of substituents on both reactants. 3-Halogenated-o-naphthoquinones 1 and 2 react smoothly with a representative vinologous ketene acetal 3, vinylketene acetals 4 and 5, and a monooxygenated diene 6 to provide variously substituted phenanthrenequinones 7–11. Only monooxygenated dienes on the other hand add to o-benzoquinones 14–16 and give convenient syntheses of the corresponding o-naphthoquinones 18–20. Keywords: cycloaddition, o-naphthoquinones, phenanthrenequinones, regiospecificity.

Abstract Reexamination of a wide range of documents surrounding the twenty-second, twenty-fourth, and twenty-fifth sessions of the Council of Trent reveals that delegates strived officially to say as little as possible about music: only that secular or impure elements should be eliminated and that specific issues should be settled locally, by individual bishops and provincial synods. But, beginning with Gustave Reese, several scholars have misleadingly strung together a preliminary canon, stressing textual intelligibility, which was never approved in the general congregations, and the few lines that actually supplanted it, concerned only with the elimination of lasciviousness. On the other hand, a largely unrecognized or misunderstood attack on church polyphony did occur at the less familiar twenty-fifth session, when Gabriele Paleotti may have attempted to suppress elaborate music in female monasteries. Although this attempt was rejected in the general congregations, its restrictions were subsequently revived by local authorities such as Paleotti and Carlo Borromeo in their own dioceses. In the Council's immediate aftermath, reformers such as Paleotti and Borromeo once again focused on the issue of intelligibility, affording it a quasi-official status that seems to have quickly become widely accepted as “iuxta formam concilii.”

El objetivo principal de esta investigación ha sido conocer y analizar la inclusión de actividades de danza en la práctica educativa del aula de Educación Infantil desde la perspectiva de los docentes. Los participantes (N=105) han sido maestras/os que imparten docencia en el segundo ciclo de Educación Infantil en centros educativos de la Región de Murcia (España). Para la recogida de datos se ha diseñado un cuestionario ad hoc y posteriormente se ha aplicado un análisis descriptivo a la información obtenida. Los resultados reflejan que los especialistas de Educación Infantil de la Región de Murcia incluyen en sus programaciones y en su práctica docente actividades de danza. Asimismo, las consideran fundamentales en el desarrollo integral del alumnado y que este responde de forma positiva y activa a este tipo de actividades. Por otro lado, alertan de la necesidad de mejorar la oferta formativa con respecto a estas materias y la calidad y cantidad de medios y recursos para llevarlas adecuadamente a la práctica. Abstract. The main objective of this research was to learn and analyze the inclusion of dance activities in Preschool teaching practices from the perspective of teachers. Participants (N=105) were teachers who teach at the second cycle of Preschool Education in schools from the Region of Murcia (Spain). An ad hoc questionnaire was designed for the collection of data, and descriptive analysis was subsequently applied. The results reflect that specialists of Preschool Education from the Region of Murcia include dance activities in their planning and teaching practices. Likewise, they consider them fundamental for the integral development of students, who respond in a positive and active way to this type of activities. On the other hand, they call the attention on the need to improve both teacher training with respect to these subjects and the quality and quantity of resources to carry them properly into practice.

ADR (Alternative Dispute Resolution), as a non-judicial resolution of disputes, is a wide range of mechanisms that aim to put an end to a conflict without the need of conducting a trial before the court. On the other hand, the modern form of ADR is ODR (Online Dispute Resolution) – an online dispute resolution system that is the expression of the newest means of communication and technical innovations in order to help in non-judicial dispute resolving. The goal of this publication is to present the ODR platform and, in particular, to describe the process of filing a complaint by the consumer by means of it.

This chapter examines Hegel’s lectures on the history of modern philosophy in view of the tension between, on the one hand, his ambition to grasp philosophy’s past in a truly philosophical way and, on the other hand, the necessity to account for the actual particularities of a wide range of philosophical systems. Hegel’s lectures are put in relief by comparing their methodological principles to those put forward by his Kantian predecessor Tennemann. After discussing Hegel’s conception of modern philosophy as a whole, the chapter turns to his reading of Locke, Leibniz, and, in particular, Kant. In this context, it also compares Hegel’s assessment of Kant’s achievements to that of Tennemann. The chapter concludes by considering Hegel’s account of the final moment of the history of philosophy.

This chapter analyses Articles 27.5, 27.6, and 27.7 of the Vienna Convention on Diplomatic Relations. The three sections mainly centre on matters regarding the functions diplomatic couriers. According to Article 27.5, the diplomatic courier, who shall be provided with an official document indicating his status and the number of packages constituting the diplomatic bag, shall be protected by the receiving State in the performance of his functions. He shall enjoy personal inviolability and shall not be liable to any form of arrest or detention. Article 27.6 on the other hand states that the sending State or the mission may designate diplomatic couriers ad hoc. If this happens, then the provisions of Article 27.5 shall also apply. Lastly, Article 27.7 states that a diplomatic bag may be entrusted to the captain of a commercial aircraft and that he shall be provided with an official document indicating the number of packages constituting the bag but he shall not be considered to be a diplomatic courier.
