Changes in food habits amongst Norwegian adolescents in 2016 and 2019 according to gender and socioeconomic status
2021
Background: Monitoring dietary habits is important in order to identify risk groups and as a basis for targeted public health initiatives. Objective: To study trends in consumption of selected foods and beverages from 2016 to 2019 amongst Norwegian adolescents according to gender and parental education. Design: Repeated cross-sectional study amongst 25,996 adolescents, aged 14–17 years old. Consumption of selected food and beverages was measured by an online food frequency questionnaire and general linear models were applied to estimate changes in dietary habits. Results: Between 2016 and 2019, we observed a reduced frequency of consumption of vegetables (from 4.7 to 4.4 times/week), fruit …
Time-like Proton Form Factors with Initial State Radiation Technique
2022
Electromagnetic form factors are fundamental quantities describing the internal structure of hadrons. They can be measured with scattering processes in the space-like region and annihilation processes in the time-like region. The two regions are connected by crossing symmetry. The measurements of the proton electromagnetic form factors in the time-like region using the initial state radiation technique are reviewed. Recent experimental studies have shown that initial state radiation processes at high luminosity electron-positron colliders can be effectively used to probe the electromagnetic structure of hadrons. The BABAR experiment at the B-factory PEP-II in Stanford and the BESIII experim…
Carbon Nitride-Based Catalysts for High Pressure CO2 Photoreduction
2022
In the current research, the productivity of CO2 photoreduction has been boosted by performing the reaction in an innovative photocatalytic reactor, which allows for operation up to 20 bar. A set of photocatalysts were used, including three types of pristine TiO2, i.e., one commercially prepared (Evonik P25), one home-prepared by flame spray pyrolysis (FSP), and one obtained by the hydrolysis of TiCl4 (TiO2exCl), a bare thermo-exfoliated carbon nitride (C3N4-TE), and binary materials composed of TiO2 and C3N4-TE. The photoreduction was carried out in water at pH 14 and in the presence of Na2SO3 as a hole scavenger. Hydrogen and very small amounts of CO were detected in the head space of the…

Path-dependencies, constrained transformations and dynamic agency. An accounting case study informed by both ANT and NIS
2013
Purpose – The purpose of this paper is to discuss the compatibility of actor network theory (ANT) and new institutional sociology (NIS) in analysing a case study of accounting change. Design/methodology/approach – This is an interpretive case study. Findings – The Finnish case city experienced several path-dependent changes concerning performance measurement (PM), financial reporting and the adoption of enterprise resource planning system (ERP). New tools such as the ERP have a potential to transform the actors and to change the agency of the actors. Furthermore, the concepts drawing on both ANT and NIS can together enrich analyses of accounting changes. Research limitations/implications – …
Akateemisen varhaiskasvatuksen muotoutuminen
2001
Tässä tutkimuksessa rajaudutaan tarkastelemaan varhaiskasvatusta tieteenalan perspektiivistä. Tutkimuksessa tarkastellaan akateemisen kentän muotoutumista ja varhaiskasvatuksen sisällöllistä määrittymistä. Aineistona ovat Suomen varhaiskasvatuksen professoreiden virantäyttöprosesseissa tuotetut dokumentit. Tutkimuksemme painottuu erityisesti akateemisen kentän keskeisten toimijoiden - asiantuntijoiden ja viranhakijoiden - identifioimiseen. Työmme kohdentuu lähihistoriaan ja sitä voidaan luonnehtia akateemisen varhaiskasvatuksen kentän historiaa ja muotoutumista koskevaksi perustutkimukseksi. Aineistolähtöinen sisällönanalyysi osoittaa, etteivät asiantuntijalausunnot juurikaan tuo yllätyksiä…
Burnout syndrome assessment among Spanish oral surgery consultants: A two populations comparative pilot study.
2021
Background The professional Burnout Syndrome (BOS) or Burnout is considered a professional disease made up of three interrelated dimensions (emotional exhaustion, depersonalization and lack of personal fulfillment). BOS has been documented to most severely affect the healthcare professions, especially dentists. On the other hand, its appearance has been documented at an early age, during dental training. However, there are no studies that analyze its incidence in professionals dedicated to Oral Surgery and Implantology, determining the age of onset and related factors. Material and Methods The modified Maslach questionnaire was carried out anonymously among the professors and students of th…
Estudio comparativo in vitro de distintos métodos de extracción de tornillos fracturados en implantes
2022
En los tratamientos sobre implantes, pueden aparecer complicaciones como la fractura de los tornillos que sujetan las prótesis que van sobre ellos. El objetivo principal de esta investigación fue evaluar in vitro la efectividad de los sistemas mecánicos de extracción de tornillos fracturados en implanto-prótesis. Material y Método: Se utilizaron 180 muestras que consistían en un implante de conexión interna Sweden&Martina® con un pilar prefabricado de titanio Sweden&Martina®, que se atornillaba al implante con un tornillo de titanio, de la misma casa comercial. Cada una de las muestras fue sometida a una carga cíclica y posteriormente a una carga de compresión hasta conseguir la fractura de…
Sex differences in food choices, adherence to dietary recommendations and plasma lipid profile in type 2 diabetes
2016
Background and aims Diabetic women have a more adverse plasma lipid profile than men. Sex differences in dietary habits may play a role, but are little investigated. The study evaluates the quality of diet, adherence to the nutritional recommendations of the Diabetes and Nutrition Study Group and their relation with plasma lipid in men and women with diabetes. Methods and results We studied 2573 people, aged 50–75, enrolled in the TOSCA.IT study (clinicaltrials.gov; NCT00700856). Plasma lipids were measured centrally. Diet was assessed with a semi-quantitative food frequency questionnaire. Women had a more adverse plasma lipid profile than men. Women consumed significantly more legumes, veg…
Firms’ distance to the European productivity frontier
2022
AbstractIn this article we explore the factors contributing to reduce the distance of laggard firms to the European frontier, focusing on institutional factors. To characterize Total Factor Productivity frontier firms within industries for the European Union we use firm level data from AMADEUS for the period 2003–2014. Our findings provide evidence on the importance of governance quality and easiness in getting credit in explaining the distance of laggard firms to the European productivity frontier. We also find that other factors at the country level -tertiary education, R&D stock, and trade openness- and at the firm level -size, age, and capital-intensity- influence the distance of la…
