Decomposition of (co)isotropic relations
We identify thirteen isomorphism classes of indecomposable coisotropic
relations between Poisson vector spaces and show that every coisotropic
relation between finite-dimensional Poisson vector spaces may be decomposed as
a direct sum of multiples of these indecomposables. We also find a list of
thirteen invariants, each of which is the dimension of a space constructed from
the relation, such that the 13-vector of multiplicities and the 13-vector of
invariants are related by an invertible matrix over .
It turns out to be simpler to do the analysis above for isotropic relations
between presymplectic vector spaces. The coisotropic/Poisson case then follows
by a simple duality argument.Comment: 9 pages. The final publication is available at Springer via

(Co)isotropic Pairs in Poisson and Presymplectic Vector Spaces
We give two equivalent sets of invariants which classify pairs of coisotropic
subspaces of finite-dimensional Poisson vector spaces. For this it is
convenient to dualize; we work with pairs of isotropic subspaces of
presymplectic vector spaces. We identify ten elementary types which are the
building blocks of such pairs, and we write down a matrix, invertible over
, which takes one 10-tuple of invariants to the other
An Experimental Analysis of the Ultimatum Game: The Role of Competing Motivations
This paper forwards a new way of accounting for the experimental evidence related to the Ultimatum Game. We argue that players in this game have reasons to be both fair and self-interested, but the balance between these two considerations cannot be expressed in terms of a tradeoff. We test our thesis by perturbing the Ultimatum Game in a way that emphasizes the force of self-interest considerations; the evidence we collected provides support for our thesis.
Aliciklusos β-aminosavak szelektív funkcionalizálása = Stereoselective functionalization of alicyclic β-amino acids
Az aliciklusos ß-aminosavak szelektív funkcionalizálását az aminosavak ciklopentén- illetve ciklohexén vázán levő olefinkötés átalakításával végeztük. Az egyik megközelítés szerint a gyűrű kettős kötésének sztereoszelektív epoxidálási reakcióját követő szelektív oxirán nyitással és egyéb transzformációkkal építettük ki az új funkciókat, melynek során ortogonálisan védett ciklusos diaminokarbonsav származékokat, azido-aminociklopentanolok sztereoizomerjeit, triazol-szubsztituált ciszpentacin származékokat, regio- és sztereoszelektíven hidroxilált ciklusos aminosavakat állítottunk elő. A második funkcionalizálási stratégia az olefinkötésre történő 1,3-dipoláris cikloaddíción alapult, amelynek eredményeként izoxazolin gyűrűvel kondenzált ciszpentacin származékok regio- és sztereoizomerjeihez jutottunk. A harmadik funkcionalizálás kulcseleme az aliciklusos ß-aminosavak oxidatív gyűrűnyitását követő reduktív gyűrűzárása volt, amely általánosan alkalmazható módszerrel új piperidin- és azepánvázas ß-aminosav származékokat állítottunk elő. Mindhárom funkcionalizálási technika alkalmasnak bizonyult a fenti vegyületek előállítására enantiomer tiszta formában is. | The functionalization of alicyclic ß-amino acids has been accomplished by transformation of their ring carbon-carbon double bond. An approach toward functionalization consisted in the stereoselective epoxidation reaction of the ring olefinic bond, followed by selective oxirane opening and other type of transformations, which resulted in orthogonally protected cyclic diaminocarboxylates, azidoaminocyclopentanol stereoisomers, triazole-substituted cispentacin derivatives, regio- and stereoselectively hydroxylated cyclic amino acids. The second functionalization strategy involved 1,3-dipolar cycloaddition to the ring carbon-carbon double bond, affording isoxazoline-fused cispentacin regio- and stereoisomers. The key step of the third functionalization strategy was the oxidative ring opening followed by reductive ring closure reactions of the alicyclic ß-amino acids, which generally applicable method led to novel ß-amino acids with a piperidine or azepane skeleton. All three functionalization techniques were suitable for the synthesis of the above compounds in enantiomerically pure form

'Interim agreements' under Article XXIV GATT
AbstractThis note looks at the WTO rules and procedures applicable to the implementation period of regional trade agreements on trade in goods. In addition, it highlights some differences between law and practice and explores the implications of these divergences. Where the GATT and subsequent instruments draw a distinction between ‘full’ regional trade agreements and ‘interim’ agreements, in practice all agreements are notified as ‘full’ agreements with an implementation period. It analyses the possibility that this deviation from the law, now sanctioned in the 2006 Transparency Decision, might have some practical implications for the regulation of regional trade agreements in the WTO.This material is copyright Cambridge University Press or reproduced with permission from other copyright owners.

Talent in the Professional Practice - The Hungarian higher education with a practice based approach, the example of the University of Pecs
The study presents a research carried out among the students of Hungary’s one of the most successful university faculties, at the University of Pécs Faculty of Business and Economics (PTE KTK). The aim of the study is to highlight the expectations of employers and students regarding professional practice. Our results show that the employers do not focus on creativity. By employing a new staff member fast integration, adaptation, diligent and precise work becomes important. Primarily employers want to hire such appropriate person who fits into their own corporate culture. The PTE KTK students have developed emotional intelligence, which allows for better integration.After presenting the results of empirical research we give a brief overview of the Hungarian and Romanian situation of higher education on the basis of criteria for the European Higher Education Area and the Bologna process. Subsequently, we formulate our recommendations, which are primarily based on the experience of professional practice. The system of professional practice serves as a highly effective feedback, and this shows the removal of the conventional belief. Secondly, there is a demand for bipolar system of knowledge and skill-application (that manifested in competence-principle).professional practice; talent management; career management; labor market; requirements; skills of students.
