[Challenges of the grounded theory approach to a novice researcher].
The grounded theory approach has been used in nursing research since 1970. The latest methodological books describe the research process in details. However, there are many problems involved in the grounded theory approach, which especially need to be considered by a novice researcher. One of these problems is the question of how deeply and widely the researcher should get familiar with the research topic before the empirical study. The problems also include the need to focus the research problem and to choose the sampling method. Data analysis is a multistage process, which demands from the researcher sensitivity and time to work out the findings which emerge from the data. In this paper, the grounded theory approach is described as a process undertaken by the researcher. The purpose of this paper is to discuss the challenges of the grounded theory approach and the problems encountered by a researcher using the method for the first time.
Now days there are tremendous amount of videos available on internet. Entertainment video, news video, sports video are accessed by users to fulfill their different needs. Our daily routine systems are also producing huge amount of videos for example surveillance system, shopping malls, home videos etc. These videos need to be accessed for different purposes. Current research topics on video includes video abstraction or summarization, video classification, video annotation, content based video retrieval. In nearly all these application one needs to identify shots in video which will correctly and briefly indicate the contents of video. This paper compares some of the popular shot boundary detection techniques. The merits and demerits of each of the techniques are also discussed. Some experiment done are also discussed.
