- We present Nemo-Nordic, a Baltic and North Sea model based on the NEMO ocean engine. Surrounded by highly industrialized countries, the Baltic and North seas and their assets associated with shipping, fishing and tourism are vulnerable to anthropogenic pressure and climate change. Ocean models providing reliable forecasts and enabling climatic studies are important tools for the shipping infrastructure and to get a better understanding of the effects of climate change on the marine ecosystems. Nemo-Nordic is intended to be a tool for both short-term and long-term simulations and to be used for ocean forecasting as well as process and climatic studies. Here, the scientific and technical choices within Nemo-Nordic are introduced, and the reasons behind the design of the model and its domain and the inclusion of the two seas are explained. The model's ability to represent barotropic and baroclinic dynamics, as well as the vertical structure of the water column, is presented. Biases are shown and discussed. The short-term capabilities of the model are presented, especially its capabilities to represent sea level on an hourly timescale with a high degree of accuracy. We also show that the model can represent longer timescales, with a focus on the major Baltic inflows and the variability in deep-water salinity in the Baltic Sea.

- Recent studies have suggested that bone marrow cells might possess a much broader differentiation potential than previously appreciated. In most cases, the reported efficiency of such plasticity has been rather low and, at least in some instances, is a consequence of cell fusion. After myocardial infarction, however, bone marrow cells have been suggested to extensively regenerate cardiomyocytes through transdifferentiation. Although bone marrow-derived cells are already being used in clinical trials, the exact identity, longevity and fate of these cells in infarcted myocardium have yet to be investigated in detail. Here we use various approaches to induce acute myocardial injury and deliver transgenically marked bone marrow cells to the injured myocardium. We show that unfractionated bone marrow cells and a purified population of hematopoietic stem and progenitor cells efficiently engraft within the infarcted myocardium. Engraftment was transient, however, and hematopoietic in nature. In contrast, bone marrow-derived cardiomyocytes were observed outside the infarcted myocardium at a low frequency and were derived exclusively through cell fusion.

- OBJECTIVE: This study investigates the predictive validity of the Oldenburg Burnout Inventory (OLBI), and of three health indicators (depression, anxiety, and self-rated health), for long-term sickness absence (LTSA).METHODS: Questionnaires were sent to all employees in a Swedish County Council (N = 6118), and the overall response rate was 65% (N = 3976). As 82% were women, only women were included in the study. Certified LTSA data were collected.RESULTS: Logistic regression analyses showed that high scores on exhaustion, depression, and poor self-rated health increased the risk of future LTSA (≥90 days). Support for the proposed two-factorial structure of the OLBI was found, including the dimensions of exhaustion and disengagement from work.CONCLUSION: Using burnout measures might be useful to identify those at risk for LTSA, and to enable preventive solutions in organizations.

- AIM: To assess the psychometric properties of a comprehensive tool for assessing psychosocial work characteristics(the QPSNordic), focusing on measurement invariance (MI) across occupations.METHODS: QPSNordic consists of 26 scales covering task, individual, and organizational aspects of work. Multiple group confirmatory factor analyses were performed in order to elucidate MI across a variety of occupational groups.SUBJECTS: Private sector employees and health care workers from the public sector participated. Equal size (n = 500) groups from six different occupations were drawn and entered in multiple group confirmatory factor analyses for assessment of MI.RESULTS: Nine of the 24 analysed scales functioned well across all occupational groups and could thus be used for valid comparisons across professions. The majority of the remaining scales showed MI at least across some groups.CONCLUSION: With some exceptions, the QPSNordic has good psychometric properties. Scales measuring organizational aspects of work could also be used across professional groups, enabling valid comparisons between differing workplaces and occupations.

- Psychometric properties, particularly predictive validity, of scales in the General Nordic Questionnaire for Psychological and Social Factors at Work (QPSNordic) were assessed. The analysis is confined to the scales in the QPSNordic, and 24 of the 26 scales are included. A large group of Swedish county council employees (n= 3,976; response rate = 65%) participated in a study and were given the QPSNordic. Register data for long-term sick leave (>90 days), with diagnosis, were used for predictive analysis. The following main results were obtained: Reliability was generally satisfactory, confirmatory factor analysis indicated good fit, concurrent validity was good, some less often investigated organizational variables predicted sickness absence, and scales were differentially associated with absence due to psychiatric and musculoskeletal disorders. In conclusion, the psychometric testing of the QPSNordic so far suggests that it is a good instrument for assessing health-related factors at work.
