Az Európai Unió számos új lehetőséget kínált és új kihívást jelentett a 2004-ben és 2007-ben belépő 12 új tagország számára. A csatlakozás mezőgazdaságra gyakorolt hatása már a bővítést megelőzően is az egyik legtöbbet vitatott kérdés volt mind a régi tagországok, mind a tagjelöltek körében. A szerzők az új tagországok agrárgazdasági teljesítményei mögött meghúzódó tényezőket igyekeznek azonosítani a legfrissebb adatok és az eddigi tapasztalatok tükrében. Eredményeik szerint a csatlakozás alapvetően pozitív hatást gyakorolt a térség mezőgazdaságára, noha az egyes országok különböző módon éltek a csatlakozás kínálta lehetőségeikkel, ami a kezdeti adottságokkal, valamint a belépés előtti és utáni agrárpolitikájukkal magyarázható. A pozitív hatások mellett számos nehézség is felmerült - ezek közül az erős versenyben való helytállás nehézségei, illetve a kisgazdaságok hátrányos helyzete bizonyultak a leginkább meghatározónak.

A cikk Oliver Hart és szerzőtársai modelljeinek következtetéseit hasonlítja össze Williamson tranzakciós költségekre vonatkozó nézeteivel. Megmutatja, hogy a két irányzat a vállalat vagy piac kérdéskörében más eszközöket használ, de hasonlóan érvel. Megismerkedhetünk Williamson Harttal szemben megfogalmazott azon kritikájával, hogy Hart modelljeiben az alkunak nincsenek tranzakciós költségei, illetve a kritika kritikájával is. Hart elképzeléseit támasztja alá a tulajdonjogi irányzaton belül nemrégiben kialakult referenciapont-elmélet, amely kísérleti lehetőségeket is nyújt a különböző feltételezések igazolására. ____ The article compares the conclusions from the models of Oliver Hart et al. with the views of Williamson on transaction costs. It shows that the two schools use different means on the question of the firm or the market, but similar reasoning. The author covers Williamson's criticism of Hart that there are no transaction costs in his models, and also the criticism of that criticism. Hart's notions are supported by the recently developed theory of reference point within the property-right trend, which offers chances of experimental proof of the various assumptions.

The entire population of Icelandic occupational therapists were surveyed concerning characteristics and attitudes toward professionalism and educational goals. There were 87 questionnaires sent out and 80 (92%) were returned and used for analysis. This data will have a positive impact upon the development of the first Icelandic occupational therapy curriculum. Icelandic occupational therapists, in general, value academic skills over technical skills, are active in their association, willing to take on duties for the advancement of the profession and are interested in conducting research. The attitudes of the Icelandic occupational therapists were generally quite uniform. T- tests and one-way ANOVAs (p < .05) revealed some significant differences in a number of attitudes by education level, length of professional experience and country of education. The results show the importance of providing Icelandic occupational therapy practitioners with the opportunity to take part in research. This study will serve as a foundation for future studies on Icelandic occupational therapists and provide reference data for later comparison.
