The study was carried out alongside National SOM 2008. Purpose: The purpose of the survey is to explore working life and job conditions in Sweden. Wed, 13 Apr 2016 00:00:00 GMT https://researchdata.se/en/catalogue/dataset/snd0896-1 https://researchdata.se/en/catalogue/dataset/snd0896-1 University of Gothenburg The first level of living survey started within the framework of a governmental commission set up to study the prevalence and problems of low incomes. Their task was broadly defined, so beside a range of studies on income and income distributions they also commissioned a group of sociologists, headed by Sten Johansson, to study the distribution of welfare in Sweden more generally. The study by Johansson and his colleagues, undertaken in 1968, came to be known as the Level of Living Survey. From the beginning it was not the longitudinal aspect that was the novelty, but rather the fact that a wide spectrum of living conditions was studied with the survey method as such. The division of level of living into different components, inspired by the work within the UN, resulted in the following list of components included in the Swedish Level of Living Surveys: Health and access to care; Employment and working conditions; Economic resources; Educational resources; Family and social integration; Housing and neighbourhood facilities; Security of life and property; Recreation and culture; Political resources. The first survey was based on a 0.0001 random sample of the Swedish population aged 15 to 75 years of age. The interviews were made face-to-face according to a structured questionnaire covering all areas listed above. A large number of questions were asked dealing with a variety of aspects within each area. The 1968 survey was to be repeated in 1974, and the decision was made to stick to the original sample but also include new cohorts of young people and immigrants arriving to Sweden in between the survey periods. Dropped from the sample was those above 75 years of age and those who had either emigrated or died. In 1981 the third Level of Living Survey was conducted with the same sample design and by and large with the same questionnaire. When Johansson left the project in 1982 Robert Erikson became the project leader. Erikson was project leader for the fourth level of living survey, conducted in 1991. During the project period Jan O. Jonsson and Johan Fritzell also were directors of the survey work. The 1991 survey was conducted with basically the same design, except for the fact that the youngest age bracket now became 18 instead of 15. The 1991 survey was enlarged in several respects. An obvious drawback of the panel design in the Level of Living Surveys is the relatively large time-span between each survey. Partly in order to fill in these missing years the 1991 questionnaire includes a work-life history section, and educational and family histories as well, thereby broadening the longitudinal aspects of the study. A second novelty was a specific survey to all individuals previously within the sample but excluded in the 1991 survey, due to the upper age limit. The sample included all persons older than 75 in 1991 who had previously been included in the Level of Living Survey sample and had been interviewed at least once. The interviews included most of the welfare components, with the exception of work related questions and education. Instead, more detailed data on health status and functional abilities was collected, partly by means of simple test performed during the interview. The third major extension was a separate work-place study consisting of interviews with managers at the work-places of all individuals who were employed at a work-place with at least ten employees.

A battery of questions addressed work-related issues such as supervision, decision-making, autonomy, respondents formal position in the hierarchy, ownership, credentials, and income. Other work-related data describe the size, industrial sector, and government or corporate linkage of the individuals employer. Further information was gathered on the class origins of the respondents family and of the families of the respondents spouse and friends. Data on class-related experiences such as unemployment and union participation were also collected, as well as data on the division of power and labour in the household. In addition the survey contained a broad range of questions on social and political attitudes and the respondents political participation. The study is part of the multinational study ´Class Structure and Class Consciousness´ (ICPSR 8413), which includes almost identificial studies from United States, Norway, Canada, and Finland.

The change is not as evident for the high‐temperature region. CaO replaced by TiO2 gives almost no effect on the viscosity, however, as it approaches Na2O/TiO2≈2 it tends to crystallize at temperatures of 1000‐1050 °C.

Currently, different materials and methods are in use in alternative rehabilitations technologies for sewer renewal. This work was conducted to study one of these materials, which is a glass -flake reinforced polyester polymeric system, during artificial aging to provide a better understanding of the material’s performance under operating conditions when it is regularly exposed to degrading factors such as high temperature and water. Changes in the material during aging were monitored by conducting different tests, including thermal and mechanical analysis, water absorption and microscopy. The dataset was originally published in DiVA and moved to SND in 2024.

A total of 125 laypeople watched 78 short videos each of individuals experiencing a hemorrhage. Victim gender, volume of blood lost, and camera perspective were systematically manipulated in the videos. The data set consists of four variables: volume estimate, volume error, response time, and classification. Each variable has a separate sheet in the excel document. The data is from 125 individuals, each listed on a separate row with a unique ID for each individual. Each sheet includes the participant ID (anonymous number), age in years, participant sex (0 = male, 1 = female), perspective of the video clip (0 = top view, 1 = front view), and then one column for each victim gender and loss volume combination (24 total). The column label consists of M or F for male and female victim, followed by underscore and the loss volume (e.g., M_50 for male victim with 50 ml of blood loss, or F_1100 for a female victim with 1100 ml of blood loss). Volume estimates are the participants' estimate of blood loss in ml. Volume error is the estimate minus the true value, in ml. Response time is the time it took for participants to classify the bleeding as life-threatening or not, in seconds. Classification is a value from 0 to 1 for the proportion of times the participant classified that particular gender-volume combination as depicting a life-threatening blood loss .
