Nash bargaining in ordinal environments

We analyze the implications of Nash’s (1950) axioms in ordinal bargaining environments; there, the scale invariance axiom needs to be strenghtened to take into account all order-preserving transformations of the agents’ utilities. This axiom, called ordinal invariance, is a very demanding one. For two-agents, it is violated by every strongly individually rational bargaining rule. In general, no ordinally invariant bargaining rule satisfies the other three axioms of Nash. Parallel to Roth (1977), we introduce a weaker independence of irrelevant alternatives axiom that we argue is better suited for ordinally invariant bargaining rules. We show that the three-agent Shapley-Shubik bargaining rule uniquely satisfies ordinal invariance, Pareto optimality, symmetry, and this weaker independence of irrelevant alternatives axiom. We also analyze the implications of other independence axioms

The transferencial relation beyond the interpretation : reflections from the theory of Winnicott.

Este artigo reflete sobre a importância de pensar a relação transferencial na clínica psicanalítica para além da interpretação. Para isso, utiliza-se a concepção de Winnicott como referencial teórico, sendo ressaltadas a noção de holding, a regressão à dependência e a questão do uso de objetos e sua influência sobre a técnica da interpretação. Winnicott revela que na clínica com alguns pacientes, em especial os autistas e psicóticos, o objetivo da análise, antes de fornecer interpretações, é proporcionar um ambiente suficientemente bom a partir do qual o sujeito pode retomar o processo de constituição de si mesmo e da externalidade do mundo.This article reflects about the importance of thinking the transferencial relation in the psychoanalytic clinic beyond the interpretation. For this, the Winnicott’s concept is used as theoretical reference, highlighting the concept of holding, regression to dependence and the question of the use of objects and its influence on the technique of interpretation. Winnicott shows that in the clinic, with some patients, particularly autistic and psychotic, before providing interpretation, the objective of the analysis is to provide a good environment from which the subject can retake the constitution process of himself/herself and of the externality of the world

2-(4-Bromo­phen­yl)-2-oxoethyl anthracene-9-carboxyl­ate

In the title compound, C23H15BrO3, the anthracene ring system is essentially planar [maximum deviation = 0.29 (2) Å] and makes a dihedral angle of 5.74 (8)° with the mean plane of the bromo-substituted benzene ring. An intra­molecular C—H⋯O hydrogen bond generates an S(9) ring motif. In the crystal, mol­ecules are linked by C—H⋯O inter­actions, forming a two-dimensional network parallel to the ac plane. π–π stacking inter­actions are observed between benzene rings [centroid–centroid distances = 3.5949 (14) and 3.5960 (13) Å]

4-(o-Tol­yl)piperazin-1-ium chloride

In the title mol­ecular salt, C11H17N2 +·Cl−, the piperazin-1-ium ring adopts a chair conformation with the aromatic ring in a pseudo-equatorial orientation. The dihedral angle between the benzene ring and the mean plane of the piperazin-1-ium ring is 51.22 (6)°. In the crystal, N—H⋯Cl hydrogen bonds link the mol­ecules into chains propagating in [100]. Weak C—H⋯π inter­actions also ocur

On the Sets of Real Numbers Recognized by Finite Automata in Multiple Bases

This article studies the expressive power of finite automata recognizing sets of real numbers encoded in positional notation. We consider Muller automata as well as the restricted class of weak deterministic automata, used as symbolic set representations in actual applications. In previous work, it has been established that the sets of numbers that are recognizable by weak deterministic automata in two bases that do not share the same set of prime factors are exactly those that are definable in the first order additive theory of real and integer numbers. This result extends Cobham's theorem, which characterizes the sets of integer numbers that are recognizable by finite automata in multiple bases. In this article, we first generalize this result to multiplicatively independent bases, which brings it closer to the original statement of Cobham's theorem. Then, we study the sets of reals recognizable by Muller automata in two bases. We show with a counterexample that, in this setting, Cobham's theorem does not generalize to multiplicatively independent bases. Finally, we prove that the sets of reals that are recognizable by Muller automata in two bases that do not share the same set of prime factors are exactly those definable in the first order additive theory of real and integer numbers. These sets are thus also recognizable by weak deterministic automata. This result leads to a precise characterization of the sets of real numbers that are recognizable in multiple bases, and provides a theoretical justification to the use of weak automata as symbolic representations of sets.Comment: 17 page

4-(Morpholin-4-yl)-3-(trifluoro­meth­yl)­benzonitrile

In the title benzonitrile compound, C12H11F3N2O, an intra­molecular C—H⋯F hydrogen bond generates an S(7) ring motif. The trifluoro­methyl group is disordered over two orientations with a refined occupancy ratio of 0.549 (16):0.451 (16). The morpholine ring adopts a chair conformation. The benzene ring and mean plane of the morpholine ring make a dihedral angle of 58.04 (10)° with each other. In the crystal, mol­ecules are connected by inter­molecular C—H⋯F and C—H⋯O inter­actions to form R 2 2(8) ring motifs. These inter­actions also link the mol­ecules into chains parallel to the [10] direction

THE MAKING OF PROFILE VIDEO ABOUT TOURISM IN SIAK REGENCY

Tourism is very important in Indonesia. However, there are many ways to promote tourism. One of the ways is through video. In promoting tourism in Siak Regency, many people have made tourism video but only in short videos. They are advertisement videos. The duration of the videos was limited and the dubber explained the exposure of the video used Bahasa Indonesia. Therefore, this profile video about tourism in Siak Regency will help Siak Regency in promoting tourism destinations. The main purpose of this final project is to explain the processes of making a profile video about tourism in Siak Regency. The method of this study is descriptive method. There are several steps in making this video such as collecting data, providing materials recording the video, giving the subtitles, continuing proceed with the process of dubbing, and the last was editing process. This video contains of ten places and a tourism event. This video can be used in order to help students, Tourism Office of Siak Regency, local community, and especially International community get information about the history and the tourism destinations in Siak Regency easily.   Tourism is very important in Indonesia.
