Advances in the endoscopic management of malignant biliary obstruction
2020
Biliary obstruction is common in pancreatobiliary malignancies and has a negative impact on the patient’s quality of life, postoperative complications, and survival rates. Particularly in the last decade, there has been enormous progress regarding the diagnostic and therapeutic options in patients with malignant biliary obstruction. Endoscopy has given a new insight in this direction and novel techniques have been developed for the better characterization and treatment of malignant strictures. We herein summarize the available data on the different endoscopic techniques, and clarify their role in the diagnosis and treatment of malignant biliary obstructive disease. Finally, we propose an al…
Classroom discussions: Possibilities and limitations for democratic classroom practices
2017
Are students offered possibilities to experience democratic practice in classrooms? Using an analysis of empirical data from classroom discussions in lower secondary school, this article identifies and explores two different types of classroom discussions which give students different positions: a conversation in which students are positioned as ‘poll respondents’, and a more deliberative conversation which positions students as learning debaters. The two forms of classroom discussions are discussed due to the way they give different meaning to democracy, and due to whether the student positions in the classrooms imply contribution to the subject matter and what is considered valuable knowl…
"You've got the color, but you dont't have the shades" : primary education CLIL teachers' identity negotiation within the Finnish context
2018
This dissertation explores how professional identity is experienced by teachers in Content and Language Integrated Learning (CLIL) instruction. In particular, it addresses professional identity in relation to two immediate contexts of teacher activity, i.e. that of the classroom and that of the collegial community. In addition to exploring how these two sides of the professional self give rise to a broader understanding of professional identity, this dissertation also explores aspects of professional agency and the negotiation of emotions in their work. The dissertation is founded on fourteen interviews with Finnish kindergarten and primary education teachers doing CLIL. The data were thema…
Niewykonanie kary ograniczenia wolności a zastępcza kara pozbawienia wolności
2021
Artykuł odnosi się do ostatniego etapu wykonawczego kary ograniczenia wolności w przypadku jej niewykonania przez skazanego na nią sprawcę przestępstwa w kontekście orzeczenia wobec niego zastępczej kary pozbawienia wolności.

W szczególności omawia jako najdalej idące alternatywne prawnie dopuszczalne rozwiązanie modyfikujące rodzaj orzeczonej pierwotnie kary i jej wymiar wymierzonej w orzeczeniu końcowym, wobec określonego sprawcy czynu zabronionego.

il volto della morte: le maschere funerarie della sepoltura dei preti morti di Gangi
2014
riassunto — Le mummie moderne e il signifcato recondito della doppia sepoltura nelle culture mediterranee moderne sono da tempo ampiamente dibattuti. In questo lavoro si discute di una particolare “collezione” di corpi di ecclesiastici, mummifcati ed esposti in un comune montano madonita della Sicilia, Gangi. I corpi, principalmente risalenti al XIX secolo, mummifcati per colatura come nella tradizione del tempo e vestiti degli abiti talari, sono esposti nel piano sottostante della Chiesa Madre, in quella che nella tradizione è detta la “fossa dei parrini” (fossa dei preti). Le mummie, a differenza di altri siti siciliani e mediterranei, sono altresì corredate di sonetto commemorativo e di …
Towards to Sustainable Tourism – Framework, Activities and Dimensions
2013
Abstract The tourism sector is most often associated with the attractive places worth to visit, sights to be seen or entertainment. In the general opinion, tourist sector does not have any negatives - it causes hundreds of tourists coming to the country who leave money, provide jobs and disseminate local space. On the other hand, heavy tourist traffic causes a significant damage, not only to the environment, which may lead to its degradation, but it also has a negative impact on the local community - for example, tourists bring a Coke or McDonalds’, the things unknown for one region, for example and they can lead to tooth decay or obesity. Fortunately, for many years many attempts have been…
A Repository for Multirelational Dynamic Networks
2012
Nowadays, WWW contains a number of social media sites, which are growing rapidly. One of the main features of social media sites is to allow to its users creation and modification of contents of the site utilizing the offered WWW interfaces. Such contents are referred to as user generated contents and their type varies from site to site. Social media sites can be modeled as constantly evolving multirelational directed graphs. In this paper we discuss persistent data structures for such graphs, and present and analyze queries performed against the structures. We also estimate the space requirements of the proposed data structures, and compare them with the naive "store each complete snapshot…
A Generic Architecture for a Social Network Monitoring and Analysis System
2011
This paper describes the architecture and a partial implementation of a system designed for the monitoring and analysis of communities at social media sites. The main contribution of the paper is a novel system architecture that facilitates long-term monitoring of diverse social networks existing and emerging at various social media sites. It consists of three main modules, the crawler, the repository and the analyzer. The first module can be adapted to crawl different sites based on ontology describing the structure of the site. The repository stores the crawled and analyzed persistent data using efficient data structures. It can be implemented using special purpose graph databases and/or …
