Financing the energy transition ::analysis and solution within the Swiss legislative framework
No full textThis paper investigates new financing solutions to facilitate energy transition in the real estate renovation sector. Recognizing financing as a significant barrier to energy efficient renovations, the study aims to understand the role of investors and to develop innovative financial products. Our approach involved conducting detailed interviews with key financial sector stakeholders, including banks, pension funds, and fund managers, to gage their perspectives on current challenges and to explore novel financing hypotheses. This was achieved through the co-design methodology. The findings indicate that while mortgages remain the prevalent financing method for renovations, there is a pressing need for more tailored financial products that can address issues related to insufficient equity and borrowing capacity. The research underscores the potential of a hybrid financial product that combines features of Energy Performance Contracting, leasing, crowdfunding, and secured financing, providing a more flexible and accessible financing avenue for energy renovations. This new financial model needs field testing to confirm its effectiveness and suitability within the Swiss energy renovation context
When should a researcher stop researching? an exploratory study
No full textThis paper presents a study aimed at defining the limits of research, by asking when a researcher should stop investigating. The question seems obvious at first glance, but our exploratory research shows that the answers vary greatly depending on the context of the research. The learnings from this research are intended to provide food for thought for students, entrepreneurs, and researchers, to shed light on the limits of research, the conditions of validity and the biases limiting the validity of the knowledge creation at the end of research, as well as other characteristics allowing or obliging the researcher to stop. This paper also compares different epistemological approaches to the definition of the term of the knowledge project and its limits. The methods used to answer this question include a purposeful literature review, as well as interviews with selected experts from different research fields such as social sciences, management, business informatics, sociology, geography, engineering, and entrepreneurship, as well as research and development experts in several Swiss SMEs. In conclusion, this paper summarizes what we have learned about the definition of the term "research"
Family ownership and the accrual anomaly
No full textMotivated by the unique nature of family firms and the puzzling persistence of the accrual anomaly worldwide, we study the effect of family ownership on the presence and the economic significance of the accrual anomaly. We propose and explore three possible channels linked to family ownership: agency problems, information uncertainty, and barriers to arbitrage. Using a sample of 27,117 observations from 34 capital markets, we find that the negative relation of accruals with future earnings performance and stock returns is more pronounced in family firms than in non-family firms. The economic significance of this finding is highlighted by portfolio-level analysis, which shows that the accrual anomaly is more profitably exploited by family firms with an annual hedge abnormal return of 18.7% versus 3.4% for non-family firms. Our findings are robust to investors sophistication, different measures of family ownership, and the institutional environment
Converting infiltration swales to sustainable urban drainage systems can improve water management and biodiversity
No full textSustainable Urban Drainage Systems (SUDS) are ecosystems that are based on engineered soil and designed plant communities to manage stormwater on-site and to enhance infiltration, evapotranspiration, and cooling, thus reducing flooding and urban heat islands. In addition, SUDS may act as hotspots for biodiversity and could be more socially accepted if they work well and are multifunctional. However, we still lack a critical understanding of the techno-ecological basis to construct SUDS sustainably. Due to climate change and pollutants such as de-icing salts, SUDS are confronted with harmful environmental triggers that interfere with their sustainable development. Thus, the challenge is to combine stormwater treatment and urban drainage with principles of restoration ecology, while implementing expertise from soil science, microbiome research, and plant ecology. In this perspective paper, we will discuss the SUDS development and maintenance principle and the role of interdisciplinary research in reaching these goals
The CLEF 2024 monster track ::one lab to rule them all
No full textGenerative Artificial Intelligence (AI) and Large Language Models (LLMs) are revolutionizing technology and society thanks to their versatility and applicability to a wide array of tasks and use cases, in multiple media and modalities. As a new and relatively untested technology, LLMs raise several challenges for research and application alike, including questions about their quality, reliability, predictability, veracity, as well as on how to develop proper evaluation methodologies to assess their various capacities.
This evaluation lab will focus on a specific aspect of LLMs, namely their versatility. The CLEF Monster Track is organized as a meta-challenge across a selection of tasks chosen from other evaluation labs running in CLEF 2024, and participants will be asked to develop or adapt a generative AI or LLM-based system that will be run on all the tasks with no or minimal task adaptation. This will allow us to systematically evaluate the performance of the same LLM-based system across a wide range of very different tasks and to provide feedback to each targeted task about the performance of a general-purpose LLM system compared to systems specifically developed for the task. Since the datasets for CLEF 2024 have not yet been released publicly, we will be able to experiment with previously unseen data, thus reducing the risk of contamination, which is one of the most serious problems faced by LLM evaluation datasets

Quand les trois fabriques suisses ont fermé dans les années 1990, la plupart de leurs archives ont été détruites. Par conséquent, cette étude s’est rapidement transformée en une enquête très détaillée visant à documenter cette période de l’histoire à l’aide de sources primaires. Rassemblant des informations et des documents éparpillés dans de nombreux lieux, cet ouvrage dévoile des images inédites et éclaire un chapitre méconnu de l’histoire industrielle et typographique, tant au niveau local qu’international
Explainable AI-guided optimization of EMG channels and features for precise hand gesture classification ::a SHAP-based study
No full textExtraction of the correct and efficient descriptors of muscular activity plays a vital role in tackling the challenging problem of myoelectric control of powered prostheses. This work presents a feature extraction framework that aims to enhance the representation of muscular activities by increasing the amount of information that can be extracted from individual and combined electromyogram (EMG) channels. The proposed method for feature selection is based on Shapley Additive explanations (SHAP). The SHAP value is used to reduce the feature dimension. The proposed approach has been evaluated on two datasets obtained at a sampling rate of 1 kHz through a band consisting of seven EMG channels. The Standard deviation (SD) and Integrated EMG (IEMG) of electrodes 3, 5, 6, and 7 recognized four motions with a classification accuracy of 98.42%±1.16% and six gestures with a classification accuracy of 96.6%±0.91%, respectively. In the present work, an ensemble technique called bagging in the random forest algorithm has been used to obtain the optimum results
Innføring av praksis i prosjektledelsesutdanningen ::kan seriøse spill bygge bro mellom teori og praksis ?
No full textWe explore the dynamic landscape of practice-oriented teaching in higher education, focusing on effectively integrating educational games (serious games) to impart management and economic concepts. The effects of and reasons for using games and simulations in management teaching is relatively well known, but the varied impact and use of different types of games is less explored. Therefore, this chapter contributes with a comparative analysis of various game types, including role-based play, simulations, system dynamics, and decision tree logic-based games. It elucidates their unique pedagogical strengths and applications across various management disciplines. By examining the diverse spectrum of educational games, educators can strategically select and employ these tools to engage students, foster critical thinking, and cultivate practical skills in management education
