Extended lymph node dissection in patients with urothelial cell carcinoma of the bladder: can it make a difference?

OBJECTIVE: We compared extended and limited lymph node dissections performed during radical cystectomy with regard to impact on survival and time to recurrence in bladder cancer patients. METHODS: We analyzed 170 patients who underwent radical cystectomy for urothelial carcinoma between January 1997 and December 2005. From 1997 to 2000, 69 of the patients were subjected to limited lymph dissection

Makt och biologi

Managementböckerna fortsätter att strömma ut på marknaden. I mångfalden är det givet att man finner en och annan bra och en och annan dålig bok. Ingvar & Sandberg lanserar inte mycket nytt, utan förmår endast knyta an till en idag ganska kraftlös sociobiologisk trend. Bennis & Nanus bryr sig inte så mycket om trender. De har en självständighet i sitt sökande efter ledarskapets "själ"... Ja

The Highest Force Hypothesis : Subordination in Swedish

This study discusses subordination in Swedish from the perspective of three construction types that involve clauses that have traditionally been difficult to classify as unambiguous main or subordinate clauses: “embedded V2”-constructions, direct speech constructions, and exclamatives. A general hypothesis regarding subordination and "superordination” is proposed: The Highest Force Hypothesis. The

Making MLSD decisions by thresholding the matched filter output

This paper presents an iterative detector that, by thresholding the output of the matched filter, gives maximum-likelihood sequence detector (MLSD) decisions on binary, antipodally modulated symbols that have been corrupted by intersymbol interference and additive Gaussian noise. The detector will make decisions on some, but often not all, of the symbols in a transmitted sequence, and those decisi

Mellan "jag" och andra. Nätbaserade studentdialoger med argumentering och responsgivning för lärande

The thesis is about how students can learn to use argumentation and the processes of giving responses in a web-based setting, as a tool for individual and collective learning. The thesis comprises three studies, which examine and describe how 70 distance students develop an individual and collective competence to provide feedback, critically evaluate and argue in the context of a web-based learnin
