A poset Q is called n-normal, if its every prime ideal contains at most n minimal prime ideals. In this paper, using the prime ideal theorem for finite ideal distributive posets, some properties and characterizations of n-normal posets are obtained.
The author presents a historical overview of company newspapers published in Wrocław and two nearby towns — Brzeg Dolny and Jelcz-Laskowice — where large industrial plants employing thousands of people living in the Lower Silesian capital were located. The article consists of two parts. In the first the author quotes the definition of company press, discusses its function and on the basis of figures from Ruch Wydawniczy w Liczbach [Polish Publishing in Figures] from 1968–1992 presents the publication frequency and geography of such publications with regard to the whole country. Part two is devoted to company newspapers published in the region referred to in the title. Drawing on an analysis of archive material kept in the State Archives in Wrocław, especially documents produced by the Regional Committee of the Polish United Workers’ Party in 1971–1978, the author examines the party nature of these publications and the requirements imposed on their editorial teams. She analyses the following publications in chronological order: Pafawag (1946–1990), Ku Nowemu (1954–1990), Żeglarz Odrzański (1954–1981), Życie Załogi (1956–1981), Nasze Problemy (1969–1990), Intermoda (1972–1981), Elwro (1973–1981), Polar (1976–1981), as well as one from Brzeg Dolny (Głos Rokity, 1954–1981) and Jelcz-Laskowice (Głos Jelcza 1962–2001). She points to formal features like format, size and circulation; editorial features, especially changes in the graphic layout of the headpiece; lists members of the editorial teams and briefly describes the profile of each newspaper in question.
