  1. 1. Decoding Decision-Making: Comparative Insights from Differently Structured Organizations

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Matilda Blomstrand; Olivia Zakrison; [2023-06-29]
    Nyckelord :centralized decision-making; decentralized decision-making; organizational structure; responsibility; accountability;

    Sammanfattning : The world is constantly changing and for organizations to stay competitive in a dynamic environment, they need to practice efficient decision-making. Previous research distinguishes decision-making as a continuum between centralized and decentralized, the former as common in hierarchical structures and the latter a characteristic of a flat structure.

  3. 2. Unsupervised Online Anomaly Detection in Multivariate Time-Series

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datorteknik

    Författare :Ludvig Segerholm; [2023]
    Nyckelord :unsupervised; online; anomaly detection; explainable ai; machine learning; mahalanobis distance;

    Sammanfattning : This research aims to identify a method for unsupervised online anomaly detection in multivariate time series in dynamic systems in general and on the case study of Devwards IoT-system in particular. A requirement of the solution is its explainability, online learning and low computational expense. LÄS MER

  4. 3. The Moderating Role of Employee Skill on the Relationship between R&D Intensity and Firm Performance

    Magister-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Devansh Sharma; Wanni Arachchige Ishan Asiri Kumara; [2023]
    Nyckelord :Research Development; Return on Assets; Market Capitalization; Employee Training; Employee Productivity; Business and Economics;

    Sammanfattning : This paper investigates the moderating effect of employee skill, as measured by employee productivity and training, on the relationship between R&D spending, measured as R&D intensity, and firm performance, measured as ROA, for the accounting-based standard, and market capitalization, for the market-based standard. The study employs a hierarchical Pooled OLS logistic regression and a Fixed Effects regression model, to account for the structure of the panel data. LÄS MER

  5. 4. Revisionsföretagens attraktionskraft : Går medelstora revisionsföretagen sin egen väg?

    Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Handelshögskolan (from 2013)

    Författare :Jessica Bäck; Cajdert Emma; [2023]
    Nyckelord :Medium-sized audit firms; attractiveness; staff turnover; organizational structure; Medelstora revisionsföretag; attraktionskraft; personalomsättning; organisationsstruktur;

    Sammanfattning : Inom revisionsbranschen har attraktionskraften till yrket minskat och antalet revisorer har gradvis blivit färre den senaste tiden. Revisorer har dock en lika viktig funktion i samhället idag och förväntas även ha det i framtiden. LÄS MER
