The dissertation completes research that began in late 2007. It presents research findings concerning ways and methods of (re) construction of gender identities of Czech children placed in facilities for institutional and protective education. Based on ethnographic research in Diagnostic institute Ark there are examined practices and techniques shaping gender roles and contents, which are rooted in the so-called helping professions discourses. Psychology, special education, social work, pedagogy, education and health education are specializations that converge are under the roof of the institutes and create a discursive field for the exercise of power-colored procedures disciplining the children who are placed (cf. Laan, 1998). These procedures are directly linked to the concepts of socially desirable sex-gender order. The research objective was to capture the processes which have been neglected by the Czech professional community so far and which may become potential disciplination instruments in the hands of professionals in a wide range of helping professions, including social and special pedagogy.

Transformatorstationer i det svenska elnätet innehar en vital funktion för att försörjningen av elenergi från producent till konsument skall fungera. Stationerna finns på olika spännings-nivåer – men de har alla en sak gemensamt: Behov av att lokalkraftsförsörjningen skall fungera enligt angivna krav. Försörjningen av en stations lokalkraftanläggning kan ske på flera olika sätt. I rapporten belyses alternativen stationstransformator, externt abonnemang, ok-lindning och ABB:s SSVT (Station Service Voltage Transformer). De olika lösningarna karaktäriseras av olika tekniska och ekonomiska aspekter och tillhörande för- respektive nackdelar. Studien utvärderar de fyra olika lokalkraftslösningarna ur ett helhetsperspektiv. Först redogörs för den bakomliggande grundläggande teorin kring lokalkraft och elkraftsekonomi. Därefter jämförs de tekniska och ekonomiska skiljaktigheterna gentemot varandra för respektive given transformatorstationstyp; fördelnings-, region- och stamstation. Vattenfall eftersöker de teknisk-ekonomiskt bästa lokalkraftsalternativen för deras transformatorstationer och rapporten skall fungera som underlag. Ur rapporten kan följande resultat och slutsatser erhållas: • Fördelningsstation: Stationstransformator och ok-lindning rekommenderas då de erbjuder teknisk funktionalitet till ett ekonomiskt försvarbart och likvärdigt pris. • Regionstation: Primärt rekommenderas alternativet ok-lindning. • Stamstation: Likväl som på de andra stationerna rekommenderas ok-lindning för försörjning av lokalkraft. Sammanfattningsvis erbjuder alla fyra alternativ de tekniska krav som finns för lokalkraftsförsörjning, men att en avvägning av vilken lösning som lämpar sig bäst för respektive transformatorstation bör utföras från fall till fall. / Substations in the Swedish electric power network have a vital function regarding the supply of electric energy from producer to consumer. The substations are represented on different voltage levels in the network – but they all have one thing in common: The need for auxiliary power to function as intended. There are different options for the supply of substations auxiliary feed. In the thesis the following alternatives are described holistic: local transformer, external power subscription, auxiliary winding on ordinary transformer, and a new (for the Swedish market) alternative from ABB called SSVT (Station Service Voltage Transformer). The distinct solutions are characterized with different technical and economic aspects and associated pros and cons. The study evaluates the four different auxiliary power solutions from a holistic view. First, the underlying essential theory about auxiliary power and electrical power economy is explained. Afterwards, the technical and economical differences are visualized for each of the solutions, and in comparison to each other for each defined substation type; distribution, region and national substation. The company Vattenfall strives for the best technical-economical alternatives for their different types of substations and the report intends to act as a supportive document. From the report, the following results and conclusions can be obtained: • Distribution substation: Local transformer and auxiliary winding is recommended due the technical functionality relative to its equivalent economic aspects. • Region substation: Primarily, the auxiliary winding alternative is recommended, mostly because of the cost-effectiveness. There are fewer alternatives in this type of substation. • National substation: The auxiliary winding is recommended as local power solution. To sum up, all of the four alternatives fill the technical requirements, but consideration for which solution for which substation type must be done on a case to case basis.
