  1. 16. Predictions Within and Across Aquatic Systems using Statistical Methods and Models

    Författare :Peter H. Dimberg; Roger Herbert; Andreas C. Bryhn; Gesa Weyhenmeyer; Mikael Malmaeus; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lake; Water quality; Chlorophyll-a; Total phosphorus; Seasonality; Morphometry; Regression model; Probability; Markov chain; Genetic programming; Temporal-trend; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Sammanfattning : Aquatic ecosystems are an essential source for life and, in many regions, are exploited to a degree which deteriorates their ecological status. Today, more than 50 % of the European lakes suffer from an ecological status which is unsatisfactory. LÄS MER

    Sammanfattning : The gap between research and practice is well-known and has been addressed globally.The application of research-based knowledge in clinical practice has the potential to improve care quality and patient safety. LÄS MER

  4. 18. Source Language of Lexical Transfer in Multilingual Learners : A Mixed Methods Approach

    Författare :Hannah Neuser; Maria Kuteeva; Philip Shaw; Camilla Bardel; Scott Jarvis; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; multilingualism; third language acquisition; lexical transfer; crosslinguistic influence; modal differences; proficiency; recency; exposure; psychotypology; L2 status; transferability; markedness; lexical organization; activation; lexical access; English; engelska;

    Sammanfattning : The study reported in this thesis investigates the source language of lexical transfer in multilingual learners using a mixed methods approach. Previous research has shown that the source language of crosslinguistic influence can be related to factors such as proficiency, recency/exposure, psychotypology, the L2 status, and item-specific transferability.

  5. 19. Statistical tools for ultrasonic analysis of dispersive fluids

    Författare :Jesper Martinsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : This thesis focuses on the possibility of using ultrasonic measurement techniques for energy gas characterization. The idea is to combine both on-line flow measurements with non-invasive fluid characterization in the same measurement setup using the same sensor(s). LÄS MER

  7. 20. Economic Implications of Corporate Social Responsibility and Responsible Investments

    Författare :Cristiana Manescu; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Corporate Social Responsibility; Strategic CSR; Socially Responsible Investments; Sustainability; Firm Profitability; Stock Returns; Statistical Learning Techniques; Variable Selection; Smooth Splines; Regression Trees; Data Envelopment Analysis; Difference-GMM; Risk-Factor Test; Market Efficiency; Control Functions Approach.;

    Sammanfattning : Paper 1 (with Catalin Starica): This study conducts an in-depth analysis of the association between a unique ten-dimensional set of Corporate Social Responsibility (CSR) scores and firm profitability, as measured by Return on Assets (ROA). We find that non-linear (semi or non-parametric) regression methods bring important improvements in explaining profitability relative to a classical linear approach. LÄS MER
