Beyond Aesthetics : Asset Pricing Theory and the Scandinavian Art Market

This study utilizes a hedonic model to examine factors influencing the pricing of Scandinavian paintings, such as size, artist reputation, and auction house. The analysis focuses on prominent painters from Denmark, Sweden, and Norway from 1991 to 2023, constructing a comprehensive price index. Using this index, we evaluate Scandinavian art as an investment, comparing it to traditional asset classes. Additionally, the study applies the Capital Asset Pricing Model (CAPM) to analyze price movements in the Scandinavian art market and other asset classes. This research contributes to understand the dynamics of the Scandinavian art market and assessing whether it might provide an investment opportunity for art enthusiasts.nhhma

Vingt-cinq ans d’évolution de l’emploi dans les professions culturelles

En vingt-cinq ans, les professionnels de la culture ont connu une forte augmentation de leurs effectifs, bien supérieure à celle de l’ensemble des actifs. Cette expansion concerne principalement les professions des arts visuels et celles de l’audiovisuel et du spectacle vivant. La part des femmes dans les professions artistiques et culturelles évolue globalement dans la même proportion que celle constatée chez les actifs occupés entre 1995 et 2019, avec des différences selon les professions. Bien qu’une forte progression de la féminisation de certaines professions soit constatée, les femmes exerçant une profession culturelle et artistique restent légèrement moins nombreuses. Un vieillissement progressif des professionnels de la culture est observé, à l’instar des actifs occupés, avec une part de plus en plus importante des individus âgés de plus de 40 ans. En revanche, la population des non-salariés rajeunit par rapport aux salariés des domaines culturels et artistiques. Nettement plus diplômés, la part de titulaires d’au moins un bac + 3 a fortement progressé entre 1995 et 2019. Les professionnels de la culture sont également plus nombreux à être Franciliens et à avoir une origine sociale favorisée

Perception of mental health and professional quality of life in Tunisian doctors during the COVID-19 pandemic: a descriptive cross-sectional study

Introduction: few research studies about mental health problems in medical staff during the first wave of the COVID-19 pandemic have been reported. The Aim of the study is to assess the prevalence of anxiety and insomnia, affecting the professional quality of life of physicians during COVID-19 pandemic. Methods: doctors answered an online questionnaire regarding their perception of insomnia, anxiety and professional quality of life during COVID-19 pandemic with psychological parameters including the Generalized Anxiety Disorder (GAD-7), Insomnia Severity Index (ISI) and Professional quality of life version 5 (ProQOL5). Results: anxiety was found in 64.8% of the participants. This disorder was respectively moderate and severe in 12.4% and 6.7% of cases. Insomnia was found in 51.4% of respondents, 29.5% of whom worked in the COVID circuit (p=0.17). Insomnia was assessed as mild, moderate and severe in respectively 38.1%, 11.4% and 1.9% of cases. Compassion satisfaction was moderate in 72.4 of cases and high in 24.8% of cases. The entire population with low CS belonged to the 20-29 age group (p=0.019). Compassion satisfaction was statistically higher in married people (32.7%) (p=0.004). This entity varied significantly with occupational grade (p=0.003), seniority in grade (p=0.011) and working in the private health sector (p=0.046). Burnout was moderate in 73.3% and low in 26.7% of cases. Burnout was significantly higher among single people (p=0.03) and statistically altered in the staff working in the COVID unit (p=0.028). Secondary traumatic disorder was above moderate in 69.6%. Conclusion: a high prevalence of psychological symptoms was found among doctors during COVID-19. Medical health workers are in need of health protection and adequate working conditions

Influence of Tunisian Revolution on Bullying at Work in Interns and Residents

This study aims to compare prevalence and determinants of workplace bullying, in interns and residents before and after Tunisian revolution and to assess its influence on their quality of life. It was a two-step-cross-sectional study, carried out in 2009 and in 2016, in547 interns and residents in 2009 and 667 in 2016.The prevalence of workplace bullying decreased significantly (p < 10−3) between 2009 (74%) and 2016 (43.6%). It was related to the professional status, gender, seniority, deliberate choice of medicine, satisfaction, serious family problems and hobbies in 2009 while it was related to professional status, nature of specialty, deliberate choice of medical studies and the satisfaction of the practice of Medicine in 2016.Most common acts were similar between both cohorts. Median mental and physical quality of life scores were below the mean baseline scores in both cohorts with no significant difference. Despite decrease in workplace bullying rate between both cohorts, its perception has not changed. Lawful criminalization, raising public awareness to reduce this phenomenon and prevent its negative effects are preventive measures to apply

Influence of shift work on the physical work capacity of Tunisian nurses: a cross-sectional study in two university hospitals

Introduction: This study has been performed to determine the influence of rotating shift work on physical working capacity of Tunisian nurses and to design recommendations to managers so that they implement effective preventive measures. Methods: It is a cross-sectional design using a standardized questionnaire and many physical capacity tests on a representative sample of 1181 nurses and nursing assistants from two university hospital centers of the school of Medicine of Monastir located in the Tunisian Sahel. 293 participants have been recruited by stratified random sampling according to gender and departments. Maximum Grip strength, 30s sit-to-stand test, one leg test, Fingertip-to-Floor test, Saltsa test and peak expiratory flow were used to assess physical capacity. Work ability was assessed through the workability index.Results: Mental and physical loads were heavily perceived in shift healthcare workers (p=0.01; p=0.02). The maximum grip force was stronger in rotating shift work nurses (p=0.0001). Regarding to the seniority subgroups in each kind of work schedule, the Body Mass Index was increasing with seniority in both schedules. All the physical tests, were better in less-than-ten-year groups. Peak Flow and grip strength were significantly better in less-than-tenyear seniority in shift work group. Conclusion: There is a need to improve the design of the existing shift systems and to reduce as much as possible shift schedule as well as to avoid shift schedule for over-10-year-seniority nurses

The WRKY transcription factor family in citrus: valuable and useful candidate genes for citrus breeding

WRKY transcription factors belong to a large family of plant transcriptional regulators whose members have been reported to be involved in a wide range of biological roles including plant development, adaptation to environmental constraints and response to several diseases. However, little or poor information is available about WRKY's in Citrus. The recent release of completely assembled genomes sequences of Citrus sinensis and Citrus clementina and the availability of ESTs sequences from other citrus species allowed us to perform a genome survey for Citrus WRKY proteins. In the present study, we identified 100 WRKY members from C. sinensis (51), C. clementina (48) and Citrus unshiu (1), and analyzed their chromosomal distribution, gene structure, gene duplication, syntenic relation and phylogenetic analysis. A phylogenetic tree of 100 Citrus WRKY sequences with their orthologs from Arabidopsis has distinguished seven groups. The CsWRKY genes were distributed across all ten sweet orange chromosomes. A comprehensive approach and an integrative analysis of Citrus WRKY gene expression revealed variable profiles of expression within tissues and stress conditions indicating functional diversification. Thus, candidate Citrus WRKY genes have been proposed as potentially involved in fruit acidification, essential oil biosynthesis and abiotic/biotic stress tolerance. Our results provided essential prerequisites for further WRKY genes cloning and functional analysis with an aim of citrus crop improvement

Supraclavicular Approach to Ultrasound-Guided Brachiocephalic Vein Cannulation in Children and Neonates

The correct choice of intra vascular access in critically ill neonates should be individualized depending on the type and duration of therapy, gestational and chronological age, weight and/or size, diagnosis, clinical status, and venous system patency. Accordingly, there is an ongoing demand for optimization of catheterization. Recently, the use of ultrasound (US)-guided cannulation of the subclavian vein (SCV) has been described in children and neonates. This article gives an overview of the current use of US for achieving central venous catheter placement in the SCV or the brachiocephalic vein (BCV) in neonates. More than 1,250 catheters have been reported inserted in children and neonates for a cumulated success rate of 98.4% and the complication rate is reported to be low. The technical aspects of various approaches are discussed, and we offer our recommendation of an US-guided technique for SCV and BCV cannulation based on our experience in a large NICU setting. Although the cannulation the SCV or BCV does not substitute the use of peripherally inserted central catheters or umbilical venous central catheters in neonates, it is a feasible route in very small children who are in need of a large caliber central venous access

Ultrasound-Guided Subclavian Vein Cannulation in Low Birth Weight Neonates

OBJECTIVES: Central venous access in critically ill, small infants remains technically challenging even in experienced hands. Several vascular accesses exist, but the subclavian vein is often preferred for central venous catheter insertion in infants where abdominal malformation and/or closure of the vein preclude the use of umbilical venous catheters, as catheterization of the subclavian vein is easier in very short necks than the internal jugular vein for age-related anatomical reasons. The subclavian vein approach is yet relatively undescribed in low birth weight infants (i.e., \textless 2,500 g), and this study aims to explore the feasibility of this technique in very small infants. DESIGN: Retrospective data collection of prospectively registered data on central venous catheter insertion in infants. SETTING: Neonatal ICU and PICU at a university hospital. PATIENTS: One hundred and five newborn children hospitalized in at the ICU. INTERVENTIONS: An ultrasound-guided supraclavicular approach was applied on all infants who had an subclavian vein catheterization during a 30-month period from January 2013 to July 2015. MEASUREMENTS AND MAIN RESULTS: One hundred seven supraclavicular subclavian vein catheters were placed in 105 children weighing less than 5,000 g. Among those, 40 patients weighed less than 2,500 g and 10 patients weighed less than 1,500 g. Successful central venous catheter insertion, defined as the correct placement of a functional double-lumen catheter (3F or 4F), was obtained in 97.3%. All three registered failed attempts were due to hematomas from venous bleeding and occurred in infants weighing greater than 2,500 g. No case of accidental arterial puncture or pleural puncture was registered. CONCLUSIONS: This large series of subclavian vein catheterizations in small infants demonstrates the feasibility of subclavian vein catheterizations even in very small neonates weighing less than 1,500 g
