Ez a műhelytanulmány a 2009-es versenyképesség kutatás során 317 vállalatra kiterjedő kérdőíves felmérés konkrét adataiból emeli ki az ellenőrzéssel, kontrollal összefüggő tényezőket és ezek eredményeit hasonlítja össze a hazai és nemzetközi szakirodalom ide vonatkozó elméleteivel. A kutatási kérdések arra irányulnak, hogy milyen részekből, feladatokból, tevékenységekből tevődnek össze a vezetők ellenőrzési feladatai, azok mikre terjednek ki, és mennyiben tekinthetők fejlettnek a versenyképes vállalatoknál. A műhelytanulmányban konkrétan a kontrolling eszköztár, a belső ill. pénzügyi ellenőrzés és kockázatkezelés, valamint a minőségirányítási sztenderdek, szabványok által megkövetelt ellenőrzési mechanizmusok vizsgálata történik a hazai, 50 főt meghaladó vállalkozások esetében. A műhelytanulmány a klasszikus kutatási jelentések sémájában készült, elméleti felvezetéssel és szakirodalmi áttekintéssel indít, majd második részében a konkrét versenyképesség adatbázis adatainak bemutatása történik a témában, végül összegzés, segítő szószedet és irodalomjegyzék zárja azt. _______ This workpaper is a report of controlmechanisms used by Hungarian companies. The latest stage of the Competitivness Research project started in 2009 during which data were collected from 317 Hungarian companies. Themes of this workpaper are controlmechanism, or controll-framework of the companies and connection between controlmechanism and competitiveness. Main elements of the research are: controlling aspects, internal and financial audits completed by managment including critical risks, audits according to ISO 9001:2008 standards or other standards, and the way these elements support or influence the competitiveness of the companies. The structure of this workpaper follows the common parts of other research reports. It begins with details of the theoretical background and presents main publications of the topic, than goes through several direct analisys and tests regarding the Hungarian competitiveness database of 2009. At the end the of the workpapaper a basic summary can be found with a glossary of explanations, and a bibliography of cited papers and publications.

Historically, grapevine (Vitis vinifera L.) leaf characterisation has been a driving force in the identification of cultivars. In this study, ampelometric (foliometric) analysis was done on leaf samples collected from hand-pruned, mechanically pruned and minimally pruned ‘Sauvignon blanc’ and ‘Syrah’ vines to estimate the impact of within-vineyard variability and a change in bud load on the stability of leaf properties. The results showed that within-vineyard variability of ampelometric characteristics was high within a cultivar, irrespective of bud load. In terms of the O.I.V. coding system, zero to four class differences were observed between minimum and maximum values of each characteristic. The value of variability of each characteristic was different between the three levels of bud load and the two cultivars. With respect to bud load, the number of shoots per vine had a significant effect on the characteristics of the leaf laminae. Single leaf area and lengths of veins changed significantly for both cultivars, irrespective of treatment, while angle between veins proved to be a stable characteristic. A large number of biometric data can be recorded on a single leaf; the data measured on several leaves, however, are not necessarily unique for a specific cultivar. The leaf characteristics analysed in this study can be divided into two groups according to the response to a change in bud load, i.e. stable (angles between the veins, depths of sinuses) and variable (length of the veins, length of the petiole, single leaf area). The variable characteristics are not recommended to be used in cultivar identification, unless the pruning method/bud load is known.

This paper tries to reframe the man-machine problem, which has frequently changed throughout history. Originally, a machine was a helper of man, but later became its competitor and substitute. As a consequence of this, man has been pushed out of production and possibly, out of life itself. For today, nearly all the man’s functions – except for consumption and creativity – can be furnished by machines. Creativity should have a special place because it is the last “shelter” of man in the conflict with machine. Almost every other faculty of man has more or less been simulated by technology. There are some key questions to be answered: Whom do the creative techniques serve? Is the target group the men or machines?

The article first gives an overview of the formation and the evolution of the principle of non-refoulement under international law. The different meanings of the concept in the asylum and human rights contexts are then discussed and compared, with due regard to the convergences that arose in the course of legal developments. In doing so, this short piece also draws attention to certain controversial issues and blurred lines, which have surfaced through the practical application of the prohibition of refoulement. Identifying the contours of the concept and clarifying its content and its effects may help in appreciating the implications that stem, in the current extraordinary times of migratory movements, from the fundamental humanitarian legal principles of which the imperative of non-refoulement forms part.
