The relationship between individual thoughts and the social environment has been widely studied in sociology (Weber, 1968), psychology (Lewin, 1951) and social psychology. The influence of reference groups on individual behaviour is often manifested in the decisions made by consumers while members of these reference groups are often the individual’s friends and acquaintances. Their decisions, their values and norms serve as an example for the individual. In this study the influences of reference groups are examined within the context of the family form in Hungary. The paper focuses on the nature of peer influence in single parent households and full families, to analyse the normative and informational dimensions of peer pressure and communication patterns within the family.

A tanulmánykötet három részre tagolódik. Az első rész két tanulmánya a korrupció elméleti-fogalmi kereteit tárgyalja. Ebben a fejezetben egyrészt a korrupció általunk használt fogalmának tisztázása mellett a megbízó-megbízott-kliens modell segítségével bemutatjuk a korrupció négy ideáltípusát. Míg a vesztegetést és zsarolást a megbízott és kliens közti, addig a hűtlen kezelést és csalást a megbízó és megbízott közti tranzakcióként definiáljuk. A korrupció ezen alaptípusait irányított gráfok segítségével ábrázoljuk. Másrészt kitekintünk – a többnyire a közgazdaságtan fogalmaiként használatos – információs aszimmetria és morális kockázat jelenségére, oly módon, hogy egyúttal azok politikatudományi alkalmazhatósága mellett is érvelünk. A kötet második részében empirikus elemzések és esettanulmányok segítségével mutatjuk be a korrupció sokszínű jelenségét Magyarországon. Míg médiaelemzésünkben a médiában korábban napvilágot látott korrupciógyanús esetek összegyűjtésével a tranzakciós helyzetek felmérésére és elemzésére teszünk kísérletet, addig a korrupció mélyszerkezetét vizsgálva tipikus magyarországi korrupciós hálózatok társadalmi és intézményi beágyazottságát mutatjuk be, a korrupciós tranzakciókat többszereplős, bonyolult és multiplex gráfokkal ábrázolva. Harmadik tanulmányunk a járadékvadászat és a korrupció kapcsolatát empirikus példák segítségével világítja meg, míg a fejezet utolsó két tanulmánya a villamosenergia-piac működéséről és a szélerőművek telepítésének korrupciós kockázatairól fest részletesebb képet. Végül a kötet harmadik fejezetében különböző antikorrupciós politikák elveire és azok gyakorlati megvalósítási lehetőségeire térünk ki. Ennek keretében egyfelől olyan antikorrupciós reformokat körvonalazunk, amelyek közvetlenül a korrupciós tranzakciók visszaszorítására irányulnak, illetve olyan antikorrupciós kormányzati lépéseket vázolunk, amelyek a szabályozási környezet megváltozására irányulnak. A kötet záró tanulmánya a gyakorlatra helyezi a hangsúlyt. Részint egy korrupciós helyzeteket és azok jogkövetkezményeit is bemutató esettanulmány segítségével megkönnyíti az ide vonatkozó hazai szabályozásban való eligazodást, másfelől – elsősorban vállalkozók számára – javaslatokat fogalmaz meg azzal kapcsolatban, hogy hogyan lehet megelőzni, illetve hatékonyan küzdeni a különböző korrupt tevékenységek ellen.

The work carried out by the physical oceanography group on POLARSTERN Leg ANT-V/3 concentrated on four major topics: A. A large scale survey of the eastern boundary between the Weddell gyre and the open ocean. On the way to the coastal polynya in early October 12 CTD stations were carried out between 54°30'S, 6°E and 70°30'S 8°W. Another set of 16 stations was obtained in early December on the way back north. During this transsect three current meter moorings were recovered at Maud Rise. The path between the current meter arrays was used to run an additional section to the NNE across the top of Maud Rise. B. A large scale survey of the Antarctic Coastal Current along the eastern shelf area. To obtain the water mass characteristics along the eastern Weddell shelf 36 CTD stations were carried out between Atka Bay and the Filchner Trench. Most of the stations were located on the shelf. Cross shelf sections were obtained both near Drescher Inlet and off Halley Bay, in the divergence area of the Coastal Current where the continental slope turns to the west and south of Vestkapp at Neptune's Point. A longshore section over 120 km was run north of Vestkapp. C. A mesoscale survey of the Antarctic Coastal Current off Drescher Inlet. The experimental work consisted of 37 CTD-stations and direct current measurements. The CTD-profiles were grouped into seven sections perpendicular to the coast line off Drescher Inlet extending once over 70 km but normally over 35 km. The profile depth ranged from 300 m on one section to the complete water column at two sections. Most sections consist of five stations providing highest resolution over the upper continental slope with offshore increasing spacing. The stations were chosen to represent the shelf (450 m), the shelf break (800 m), the upper slope (1600 m), the lower slope (2400 m) and the transition to the abyssal plain (3400 m). Rough topography and difficult ice conditions made it impossible to meet those requirements in all cases. D. A small scale survey of the hydrographic conditions under the sea ice. The motivation for these studies arose during the cruise. Consequently a suitable Instrumentation had to be developed at sea. This was done with a NB-Smart CTD which was inserted on an L-shaped lever through a hole in the ice. However, various water intrusions into the instrument resulted in the failure of this technique. In consequence a special lever system was built to position a NB Mark 3b weighing about 40 kg below the ice. Twenty four profiles were obtained reaching from the bottom of the ice down to 2 m below the ice surface with a maximum distance of 1 m from the entry hole. As the conductivity sensor was influenced by nearby ice platelets, salinity samples where drawn to check the sensor.

Background: Cellulitis of the lower leg accounts for 2-3% of hospital admissions (Cox et al, 1998), with an average length of in-patient stay of nine days. Studies have reported that up to half of these patients suffer further episodes (Cox et al, 1998; Dupuy et al, 1999). Reducing the recurrence of cellulitis could therefore have a significant impact on both patient morbidity and NHS costs. Aims: To assess whether prophylactic antibiotics prescribed after an episode of cellulitis of the leg results in fewer subsequent attacks and reduced health service costs (PATCH prophylactic antibiotics for the treatment of cellulitis at home). Methods: This article describes two related studies in which participants are randomised to receive either 12 months of prophylaxis (PATCH I) or six months of prophylaxis (PATCH II). The PATCH I study recruits only patients with recurrent disease defined as two or more episodes of cellulitis in the last three years. PATCH II has more open criteria and includes patients with a first episode of cellulitis and also participants with recurrent disease. It is expected that 260 patients will be recruited into PATCH I and 400 patients into PATCH II.

A investigação nas ciências humanas e sociais em geral e em educação de forma particular tem passado por muitas transformações ao longo das últimas décadas. Como todos os ramos das ciências, estas também influenciaram e foram influenciadas pelos desenvolvimentos específicos da área e das tecnologias. Há mais de 30 anos que aplicações informáticas ajudam os utilizadores a fazerem análise qualitativa de dados não-numéricos e não-estruturados, apresentando aos utilizadores resultados em forma de matrizes numéricas, trianguladas, com discurso descritivo de cariz qualitativo, que os apoia nas suas interpretações (Neri de Souza, Costa, & Moreira, 2010). O webQDA é um software de análise de texto, vídeo, áudio e imagem que funciona num ambiente colaborativo e distribuído com base na internet. O webQDA procura suprir essa necessidade, principalmente porque os projetos de investigação são cada vez mais desenvolvidos no âmbito multidisciplinar e com o envolvimento de utilizadores dispersos geograficamente. Também supre a lacuna de muitos programas que “obrigam” o(a) utilizador(a) a esperar que o(a) colega desenvolva a “sua parte do projeto”, para que lhe seja enviado o ficheiro e somente então poder inserir a sua contribuição, processo que se poderá perder num trabalho realmente colaborativo.
