Do Antidoping Interventions Work?

Andrea Petróczi Cora Burnett Cornelia Blank Eduard Bezuglov Tamara Dolmatova Tarryn Godfrey Carmen Horvat Vassil Girginov Mike McNamee Andrew Bloodworth

Publication Name: Journal of Sport and Social Issues

Publication Date: 2026-04-01

Volume: 50

Issue: 2

Page Range: 145-172

Description:

A multitude of interventions have been designed to tackle doping in sport. Despite significant advances in understanding the role of motivation, the environment, policies and education in addressing doping, there is a lack of nuanced knowledge concerning the design and implementation of these interventions. The present study adopted an intervention mapping evaluation perspective, critically evaluating a selection of 12 antidoping programs across three sports in Austria, Russia, South Africa, and the United Kingdom, using a mixed-methods, sequential, explanatory design. Findings confirm that the antidoping intervention landscape is diverse and complicated, incorporating multiple strands, sites, ambitions and stakeholders. It also suggests that the drive for policy compliance led by WADA has promoted considerable isomorphism across diverse cultural and economic communities and sports. Antidoping educational interventions appear to have been informed more by the moral imperatives for clean and fair sport rather than sound theoretical bases. While the theoretical basis on which most interventions were based can operate across culturally and economically divergent contexts, this is undermined by differences in their interpretation and the context of their implementation. Several lacunae in the design and implementation of antidoping interventions are also identified and discussed.

Development in Machine Learning Based Rapid Visual Screening Method for Masonry Buildings

O. Kegyes-Brassai Nurullah Bektaş

Publication Name: Lecture Notes in Civil Engineering

Publication Date: 2023-01-01

Volume: 433 LNCE

Issue: Unknown

Page Range: 411-421

Description:

The susceptibility of existing buildings to earthquakes is required to be assessed since building stock consists of structures that were constructed before the development of seismic standards, whether by disregarding them or by taking into account lower seismic regulations. Damage to buildings due to earthquakes not only endanger people’s lives but also causes economic losses. Because examining a large number of buildings by employing detailed building assessment methods is computationally expensive, Rapid Visual Screening (RVS) techniques are capable of assessing large building stock. Previous studies demonstrate that accuracy of the conventional RVS methods to precisely determine buildings’ damage states is limited. Therefore, it is required to develop a new RVS method. Since machine learning is extremely competent in establishing a relationship between input parameters and the target variable, this study introduces a new machine learning-based highly accurate RVS method, that can be applied in different countries, for masonry buildings using post-earthquake building screening data of 273 masonry buildings collected after the 2019 Mugello, Italy earthquake. The developed method differs from conventional RVS methods in terms of considered parameters such as spectral acceleration, the fundamental natural frequency of buildings, and the distance to the earthquake source. By comparing calculated building damage states with identified damage states through post-earthquake inspection, the developed method’s potential efficiency has been demonstrated as 88.9% accurate.

Description:

The overwhelming majority of intercontinental long-haul transportations of goods are usually carried out on road by semi-trailer trucks. Vibration has a major effect regarding the safety of the transport, the load and the transported goods. This paper deals with the logistics goals from the point of view of vibration and summarizes the methods to predict or measure the vibration load in order to design a proper system. From these methods, the focus of this paper is on the computer simulation of the vibration. An analytical method is presented to calculate the vertical dynamics of a semi-trailer truck containing general viscous damping and exposed to harmonic base excitation. For the purpose of a better understanding, the method will be presented through a simplified four degrees-of-freedom (DOF) half-vehicle model, which neglects the stiffness and damping of the tires, thus the four degrees-of-freedom are the vertical and angular displacements of the truck and the trailer. From the vertical and angular accelerations of the trailer, the vertical acceleration of each point of the platform of the trailer can easily be determined, from which the forces acting on the transported goods are given. As a result of this paper the response of the full platform-load-packaging system to any kind of vehicle, any kind of load and any kind of road condition can be analyzed. The peak acceleration of any point on the platform can be determined by the presented analytical method.

Description:

Introduction – Spirulina maxima (Sm), a blue-green microalgae, is well known for its rich nutritional composition, antioxidant, and anti-inflammatory properties. In this study, we found that small extracellular vesicles (sEVs) isolated from Sm exhibit antifibrotic activity. Methods – Sm derived sEVs (Sm_sEV) were purified from the Sm culture medium using tangential flow filtration (TFF), followed by size-exclusion chromatography (SEC). Characterization of the sEVs was performed using nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), immunogold TEM, surface-enhanced IR spectroscopy (SEIRS), and flow cytometry (FC). Internalization of DiI-labeled sEVs by human primary peritoneal mesothelial cells (P-MCs) and peritoneal fibroblasts (p-FBs) was examined using fluorescence microscopy. The effect of sEVs on mesenchymal transition of P-MCs and activation of P-FBs was investigated by immunofluorescent staining, MTT cell-proliferation, and Sirius Red collagen accumulation assays, respectively. The antifibrotic relevance of Sm_sEV was further investigated in a chlorhexidine digluconate (CG)-induced mouse model of peritoneal fibrosis. Results – The isolated Sm_sEV exhibited a spherical morphology, with a size range of 150.0 ± 67.6 nm, and the protein-to-lipid ratio (P/L_spectr) was 2.27 ± 0.07. The sEVs cargo contained Parkinson’s disease protein 7 (PARK7), and heat shock protein 70 (HSP70). DiI-labeled sEVs were successfully internalized by both P-MCs and P-FBs and inhibited TGF-β-induced mesenchymal transition in P-MCs and the collagen production and PDGF-B-induced proliferation in P-FBs. In vivo, intraperitoneal administration of Sm_sEVs reduced CG-induced submesothelial thickening, fibronectin, and collagen type I alpha 1 immunopositivity, and increased cytokeratin 18, immunopositivity in the mesothelial layer. Discussion – These findings highlight the antifibrotic effect of Sm_sEV and support their further investigation in the context of fibrosis.

Incorporating single cell proteins in the diet of IBD patients

Balázs Ásványi Judit Molnár Dávid Vasas

Publication Name: Elelmiszervizsgalati Kozlemenyek

Publication Date: 2018-01-01

Volume: 64

Issue: 4

Page Range: 2290-2296

Description:

Worldwide, and also in Hungary, more and more patients are diagnosed with inflammatory bowel disease (IBD) each year. In the case of IBD patients, to supplement a normal diet, alternative solutions, such as, for example, the dietary use of single cell proteins intended to be examined by us are required. Ensuring the proper nutrition and liquid supply of the human body is one of the major tasks of modern food science. By using state-of-the-art scientific knowledge and diagnostic methods, the energy requirement of people with increased energy and protein needs can be determined as a function of their body weight, and the production processes of foods should be realized with this information in mind. In our research, single cell proteins (SCP) have been produced in a yeast culture grown on high sugar content culture media, including their nutritional evaluation. Possibilities for incorporating SCP in the diet of IBD patients have also been investigated. With our research results, we would like to provide assistance to specialists in food science and those in nutrition science contributing to food production.

János Szép Kitti Karolyfi Nóra Géczy Rnin Salah

Publication Name: Digital Applications in Archaeology and Cultural Heritage

Publication Date: 2025-06-01

Volume: 37

Issue: Unknown

Page Range: Unknown

Description:

Heritage conservation demands innovative approaches that integrate advanced technologies with traditional principles to protect monuments and historic buildings. This research investigates the potential of Building Information Modeling (BIM) in heritage conservation, with a focus on developing and adapting workflows tailored to Heritage Building Information Modeling (HBIM). Through a systematic analysis of literature, the research highlights the adaptation of scan-to-BIM methodologies for HBIM creation and their significant role in enhancing preservation efforts. Key technologies, including laser scanning, photogrammetry, and machine learning, are discussed for their contributions to generate accurate and information-rich digital models of heritage structures. Furthermore, this work discovers critical specifications and proposes a structured framework for balancing these specifications within HBIM workflows. This framework addresses challenges such as standardization, scalability, and adaptability, which are essential for accurately capturing the complexity of heritage buildings. By examining these issues, the study identifies opportunities to improve HBIM's capability to monitor, document, and manage culturally significant assets. The findings provide a comprehensive understanding of HBIM processes and their potential to support the effective conservation of heritage.

Application of interpolation-based fuzzy logic reasoning in behaviour-based control structures

Szilveszter Kovacs Laszlo T. Koczy

Publication Name: IEEE International Conference on Fuzzy Systems

Publication Date: 2004-12-01

Volume: 3

Issue: Unknown

Page Range: 1543-1548

Description:

Some difficulties emerging during the construction of fuzzy behaviour-based control structures are inherited from the type of the applied fuzzy reasoning. The fuzzy rule base requested for many classical reasoning methods needed to be complete. In case of fetching fuzzy rules directly from expert knowledge e.g. for the behaviour coordination module, the way of building a complete rule base is not always straightforward. One simple solution for overcoming the necessity of the complete rule base is the application of interpolation-based fuzzy reasoning methods, since interpolation-based fuzzy reasoning methods can serve usable (interpolated) conclusion even if none of the existing rules is hit by the observation. These methods can save the expert from dealing with derivable rules and help to concentrate on cardinal actions only. For demonstrating the applicability of the interpolation-based fuzzy reasoning methods in behaviour-based control structures a simple interpolation-based fuzzy reasoning method and its adaptation for behaviour-based control will be introduced briefly in this paper.
