The critical incident technique was applied in analyzing the job of store managers in a Swedish grocery company. About 1800 incidents were collected, mainly by interviews, but also by questionnaires. Several reliability and validity aspects of the method were studied. When two-thirds of the incidents had been classified, 95% of the subcategories had appeared. The structure of the material was not influenced by the methods of collecting or by the interviewers. A repetition of the categorizing procedure was used to determine the stability of the subcategories. It was found that literature used in the training of personnel did not provide any additional, relevant information. Ratings of the subcategories support the assumption that the method covered the essential points in the job.
119 Swedish children were followed from their first year of life up to the age of 8. Most could be classified according to (a) type of day-care they had experienced during their first 7 years of life and (b) time of first entrance into day-care. At 8 years, the children were tested with aptitude tests and rated by their teachers on school performance and social and personal development. Hierarchical regression analyses and MANCOVAs were used in the statistical treatment. Time of entrance into day-care predicted children's cognitive and socioemotional development, controlling for sex and home background. Children with early day-care (entrance before the age of 1) were generally rated more favorably and performed better than children with late entrance or home care. There was a tendency for early center care to predict a more favorable outcome than other care.

A group of Senior high school students, 18 years old, answered a questionnaire about their perceptions of their school situation. Around one-third of the group seemed to like school very much and another third seemed to hate or dislike school very much. This group was followed up until they were 25 years old. Of the original sample 82%, 462 persons, answered a new questionnaire about how they had succeeded in life, what kind of further education they had got, what kind of job they had, how they looked upon their future job and life careers, etc.They were also asked about their memories and feelings about their former school experiences. In the analyses we relate the students' school perceptions at age 18 to their memories of school when 25. A substantial number of the respondents remembered school in the same way as they perceived school when in school. Those who hated school seemed to be more vulnerable when they were adult. We also discuss what could be done to change school so that it does not loose one-third of its students. We introduce the concept of the 'learning centre', the aim of which is to teach the joy of learning and stimulate the students' thirst for knowledge.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
