Sterkere, raskere, bedre?

2023

Fotball er en kompleks idrett med omfattende krav. Dette gjør at fotballspillere har mange ferdigheter de må utvikle for å bli best mulig. Styrketrening blir brukt til å kunne forbedre noen av de fysiske ferdigheter som fotballspiller trenger, og fysiske ferdigheter blir ofte testet gjennom isolerte fysiske tester. Denne studien har som hensikt å undersøke om det er sammenheng mellom endringer i en styrke¬intervensjon og fysisk prestasjon i fotballkamp. Problemstillingen er slik: Er det en sammenheng mellom endringer i styrkeintervensjon og endringer i sprint, akselerasjon, nedbremsing, retningsforandring samt PlayerLoadTM i offisielle fotballkamper? Det ble gjennomført en kohortstudie med …

The road over the principle bridge to successful change management

2023

Change management has over time received a greater focus, as the companies are looking for new opportunities to improve and evolve their organization by implementing changes. “Bottom up” phenomenon is becoming more emerging, as well as the worker involvement and empowerment. Lean, that normally is seen as the method to reduce waste that was first introduces and used by Toyota. Has in the later years been adapted and used in different occasions, for example to overcome challenges with change management. Moreover, principles are becoming more sought after, to explore their potential. This master's thesis involves examining a case study in collaboration with Norway's largest oil and gas compan…

Hydrodynamic response of a loam soil after wetting with different methods

2023

Different points in a field can be wetted with different natural or artificial rainfall amounts and intensities. Therefore, a non-uniform soil wetting could occur during short-term monitoring of soil hydrodynamic parameters and its global effect on soil characterization is not easily predictable. For an initially dry loam soil, a sequence of three beerkan infiltration runs was performed at fixed sampling points in a period of two weeks. Immediately after the first beerkan run, the soil was perturbed by adding an additional water volume differing with the sampling point by the amount of water (0, 100 or 227 mm) and the application methodology (rainfall simulation, another beerkan run). As co…

Stationary, Oscillatory, Spatio-Temporal Patterns and Existence of Global Solutions in Reaction-Diffusion Models of Three Species

2023

The goal of my Ph.D. research is to analyze three species models in order to describe the behavior of an ecological community. In particular, two reaction-diffusion systems describing different local interactions between three species have been considered to obtain species coexistence, diversity, and distribution patterns. The first analyzed model describes intraguild predation: there are an IG-predator species, an IG-prey species, and a common resource species, which is shared by both of them. The IGP interaction is of Lotka-Volterra type, coupled with nonlinear diffusion, since we assume that the IG-prey moves towards lower density areas of the IG-predator. In this model, the extinction o…

A systematic review of functional numeracy measures for 9–12 -year-olds: Validity and reliability evidence

2023

This systematic review aimed to summarize the characteristics and the measurement properties of functional numeracy measures developed for use by teachers among 9–12-year-old children with or without mathematical learning difficulties. A systematic search from five databases was conducted based on pre-defined criteria. PRISMA guidelines were followed for reporting the results. The terminology and classification of measurement properties adopted by the COSMIN taxonomy was used. Twenty-one studies of 18 measures met the inclusion criteria. Most of the identified measures did not report on several measurement properties due to incomplete or missing psychometric data. Knowledge of Mathematical …

Factores de riesgo en mujeres en situación de perimenopausia y menopausia y su prevención

2023

Las mujeres permanecen más de la tercera parte de su vida en estado de perimenopausia o menopausia y esta situación se ha asociado con aumento de los Factores de Riesgo Cardiovascular (FRCV) y del Síndrome Metabólico (SM), cuya progresión está relacionada con el tiempo de menopausia y estilos de vida. Así pues, los objetivos del presente estudio fueron determinar la presencia de FRCV: hipertensión arterial, dislipemia, exceso ponderal y composición corporal, en mujeres en menopausia o perimenopausia, así como estimar el aumento de grasa visceral en este periodo y su correlación con los FRCV. También, se investigó sobre el efecto de la práctica de ejercicio físico y la realización una dieta …

Can TikTok Sound Enhance Tourism SMEs’ Engagement?

2023

AbstractThis study explores the role of sound and its interaction with marketer-generated content (MGC) (i.e., emotional, informational, transactional) in influencing customer engagement (CE) (i.e., views and shares) in the context of tourism SMEs and TikTok. Content analysis was conducted to analyze data from 7 travel guide services in Indonesia. The final dataset comprised 660 TikTok videos, 4,092,289 views, and 10,920 shares. The results confirm that cover sound has no direct effect either on views or shares. Also, cover sound has no interaction effects with any MGC in impacting CE (i.e., views and shares). Individually, the MGC of emotional content has significant and positive effects o…

Depressive Symptoms and Mortality : Findings from Helsinki Birth Cohort Study

2023

Background Individuals with depression and depressive symptoms have a higher mortality rate than non-depressed individuals. The increased comorbidity and mortality associated with depression has remained largely unexplained. The underlying pathophysiological differences between depressive subtypes, melancholic and non-melancholic, may provide some explanation to this phenomenon. Methods 1995 participants (mean age 61 years) from the Helsinki Birth Cohort Study were recruited for this prospective study and followed up for a mean of 14.1 years. Information regarding medical history, lifestyle, and biochemical parameters were obtained. Depressive symptoms were assessed using the Beck Depressio…

Hyvinvointiin omista lähtökohdista

2023

Hyvin- ja pahoinvoinnin välinen suhde heijastelee sitä, miten ja kuinka laajana hyvinvointi on milloinkin ymmärretty. Käsitteen merkityksen muutokset ilmentävät myös yhteiskunnassa tapahtuneita sosiaalisia ja taloudellisia sekä myös arvopohjaisia muutoksia. Historiallisesti katsottuna ihmisten vaikeudet saavuttaa riittävä henkinen ja aineellinen hyvinvointi liittyvät niihin elinympäristöihin ja alueisiin, missä he elävät. Heitä voitaisiin auttaa ja tukea erilaisin palveluin, mutta se edellyttäisi heidän yksilöllisten elämäntilanteidensa ja tarpeidensa sekä paikallisten olosuhteiden tarkempaa huomiointia. Myös koulutus on historiallisesti tärkeä hyvinvointia vahvistava tekijä. nonPeerReviewed

Kulttuurin diagnostisoitumisen tutkimus kulttuuriteoreettisesta näkökulmasta : teoreettis-metodologisia lähtökohtia

2023

Kulttuurin diagnostisoituminen on diskursiivinen ilmiö ja prosessi, jossa lähtökohtaisesti lääketieteen taudinmääritteiksi tarkoitetut ja spesifit diagnoosinimikkeet saavat yhä keskeisemmän sijan kulttuurissa. Erityisesti tämä näkyy psykiatristen ja neuropsykiatristen diagnoosien leviämisenä psykiatrian ja lääketieteen piiristä osaksi muuta kulttuuria. Kulttuuri puolestaan hahmottuu tässä yhteydessä kulttuurintutkimuksen piirissä kehitettyjen kulttuuriteorioiden mukaisesti merkityksenannon järjestelmäksi. Tätä kulttuurin diagnostisoitumisen ilmiötä analysoidaan monilla humanistisilla ja yhteiskuntatieteellisillä aloilla. Tässä kirjan luvussa saatetaan yhteen aiemman tutkimuksen havaintoja j…

Sosial kapital som byggestein for bærekraftig samfunnsutvikling En casestudie av #vårtagder - en regional samhandlingsstruktur på Agder

2023

Formålet med studien er å se på etableringen av samhandlingsstrukturen og nettverksmodellen #vårtagder og hvordan denne regionale samhandlingen på tvers av sektorer og fagområder kan være et virkemiddel for å løse komplekse samfunnsutfordringer. Fordi nettverksmodeller ikke bare er strukturelle, men også relasjonelle og kognitive, ønsker jeg å utforske disse dimensjonene i lys av teorier innen sosial kapital. Sosial kapital, som ifølge litteraturen er essensielt for mobilisering av den kollektive drivkraften i sivilsamfunnet (Putnam 1995, referert i Normann. et. al. 2014).

Evidence of a causal effect of genetic tendency to gain muscle mass on uterine leiomyomata

2023

Uterine leiomyomata (UL) are the most common tumours of the female genital tract and the primary cause of surgical removal of the uterus. Genetic factors contribute to UL susceptibility. To add understanding to the heritable genetic risk factors, we conduct a genome-wide association study (GWAS) of UL in up to 426,558 European women from FinnGen and a previous UL meta-GWAS. In addition to the 50 known UL loci, we identify 22 loci that have not been associated with UL in prior studies. UL-associated loci harbour genes enriched for development, growth, and cellular senescence. Of particular interest are the smooth muscle cell differentiation and proliferation-regulating genes functioning on t…

Pratiche anti-oppressive e popolazione LGBTQAI+: riflessioni per la formazione in servizio sociale

2023

The aim of this work is to contribute to the Italian debate, firstly through a reconstruction of the main assumptions of Critical Social Work (CSW) whose analyses provide social workers with a critical awareness and reflexivity without which it would not be possible to link their professional practice and the daily challenges that LGBTQAI+ people face with the systemic and structural aspects of disadvantage and oppression that characterise contemporary societies. In this sense, CSW - applied to the fields of sexual orientations, gender identities and non-normative sexualities - is configured as an overall practice that invests the identities of social workers and users and their symbolic an…

Estudio observacional prospectivo de valoración perioperatoria ecográfica del diafragma (D-POCUS) para la detección del bloqueo frénico y predicción …

2023

El músculo diafragma es el principal musculo que interviene en la ventilación, siendo responsable de alrededor del 80% del trabajo ventilatorio en condiciones normales. Cuando realizamos una anestesia del plexo braquial por encima de la clavícula, la proximidad del nervio frénico provoca un bloqueo de forma frecuente, y este hecho conlleva una disfunción hemidiafragmática en grado variable. Sin embargo pocos pacientes desarrollan complicaciones pulmonares postoperatorias. Se ha prestado poca atención al hemidiafragma contralateral como parte de la función diafragmática global. Conocer con exactitud el comportamiento de ambos diafragmas (en especial el contralateral al bloqueo) es clave para…

Molecular-Biology-Driven Frontline Treatment for Chronic Lymphocytic Leukemia: A Network Meta-Analysis of Randomized Clinical Trials

2023

The treatment of chronic lymphocytic leukemia (CLL) currently relies on the use of chemo-immunotherapy, Bruton’s tyrosine kinase inhibitors, or BCL2 inhibitors alone or combined with an anti-CD20 monoclonal antibody. However, the availability of multiple choices for the first-line setting and a lack of direct head-to-head comparisons pose a challenge for treatment selection. To overcome these limitations, we performed a systematic review and a network meta-analysis on published randomized clinical trials performed in the first-line treatment setting of CLL. For each study, we retrieved data on progression-free survival (according to del17/P53 and IGHV status), overall response rate, complet…

Organisational Legitimation Strategies in Social Media : How Business Schools Address Declining Ranking

2023

Public relations scholarship has drawn on organisational legitimacy theory to show how organisations appeal to stakeholders’ acceptance of their existence and importance in society. Studies have shown how different types of organisations utilise communication strategies in social media to gain legitimacy. This chapter contributes to public relations research by examining how a sample of business schools implemented legitimation strategies in their social media posts when their legitimacy was threatened. The findings show that when ten world-class European business schools faced declining institutional rankings between 2016 and 2019, they made use of four legitimation strategies—authorisatio…

The Treatment of Old Age at Court. The Kings of Sicily from Roger II to Martin II (11th–15th Century)

Nella concezione galenica, la vecchiaia perde la sua connotazione di ineluttabile processo degenerativo per soggiacere alle stesse regole terapeutiche messe in atto per mantenere la salute e prolungare la vita. L'aspirazione a ritardare i malanni della vecchiaia, richiamando e riproponendo il mito della prolongatio vite, anima il pensiero e l'operato di quanti (filosofi, medici) diventarono figure di riferimento per i sovrani siciliani. Analizzando i contesti culturali che videro l'isola attraversare varie dominazioni (normanna, sveva, angioina, aragonese), il contributo si propone di mettere a fuoco le strategie seguite dai re di Sicilia vissuti più a lungo - in tal senso il concetto di ve…
