A cross-sector analysis of consumer intention towards sustainable product-service systems: Evidence from mobility, clothing and tooling
No full textpeer reviewedSustainable Product-Service Systems (SPSS) offer a promising solution to sustainability challenges in modern consumption. Yet, enduring adoption of SPSS by consumers is still uncertain and identifying the factors affecting SPSS adoption is complex. This study investigates the drivers and barriers (D&B) of SPSS adoption intention, analysing their variations across three distinct areas of need: mobility, clothing, and tooling. A comprehensive framework is constructed to categorize D&B into cognitive, attitudinal, comparative, and emotional factors, drawing upon extensive literature. The significance and intensity of these D&B are empirically assessed through a survey of Brussels consumers, revealing variations among areas of need. From this analysis, three distinct categories of D&B are identified: generic ones, transcending area-specific differences (e.g., the financial advantage); irrelevant ones, exhibiting general non-significance across all areas (e.g., the absence of maintenance worries); and area-specific ones, pertinent to certain, but not all, areas of need (e.g., the consumerist attitude in the tooling area of need). This study contributes to an enhanced understanding of SPSS adoption, offers valuable insights for businesses to tailor their strategies and promotes sustainable consumption practices

How does entrepreneurial experience shape decision-making and cognitive flexibility?
No full texteditorial reviewedEntrepreneurs evolve in an environment requiring cognitive flexibility— the ability to adapt to new and changing situations— and decision-making under uncertainty. Especially, they often have to choose between exploring new options or exploiting already known ones. This kind of decision is underpinned by cognitive flexibility abilities. Recent studies evidenced that higher cognitive flexibility in experienced entrepreneurs is associated with differences in brain structure and function compared with managers. However, whether this heightened cognitive flexibility is an inherent trait of entrepreneurs or develops through experience remains unclear. This work aims to investigate if entrepreneurial experience modifies decision-making strategies through the evolution of cognitive flexibility abilities. The study will involve 90 entrepreneurs at various career stages and 30 employees without entrepreneurial experience, who will perform cognitive tasks assessing decision-making and cognitive flexibility. Decision-making strategies will be evaluated using a two-armed bandit task designed to manipulate novelty and uncertainty of stimuli, addressing exploration-exploitation strategies. We hypothesize that decision-making strategies evolve with entrepreneurial experience, with more experienced entrepreneurs exhibiting greater exploratory behaviour. We propose that this effect is mediated by an increase in cognitive flexibility associated with entrepreneurial experience. By disentangling the effects of entrepreneurial experience on decision-making under uncertainty, this study will provide insights into the influence of specific environments on decision-making and cognitive flexibility—key prerequisites for success in today’s information-rich world
Digitization and calibration of historical solar absorption infrared spectra from the Jungfraujoch site
No full textpeer reviewedThis study describes the digitization and calibration of historically significant solar absorption spectra recorded at the Jungfraujoch International Scientific Station in the 1950s. Using a homemade Pfund-type grating spectrometer, these spectra were recorded on paper rolls to study the solar spectrum which was then used to compile a solar atlas between 2.8 and 23.7 µm (421 to 3571 cm−1) that, in particular, later contributed to the development of the HITRAN (High-Resolution Transmission Molecular Absorption Database) database. We have now digitized these analogue recorded spectra to make them available for atmospheric studies. Our approach involves image-processing techniques, including colour masking for digitization and peak detection for accurate wavenumber calibration against a synthetic spectrum.
We have also developed a validation method by re-digitizing degraded Fourier transform infrared (FTIR) spectra to the same resolution as the old spectra to evaluate the digitization accuracy. Furthermore, we have studied the influence of line thickness on the digitization error.
The number of spectra transformed into a machine-readable format is 106 (freely available for download), with an average digitization error of 1.55 % and a wavenumber shift standard deviation of 0.075 cm −1. These digitized and calibrated spectra now offer a valuable resource for atmospheric studies, providing essential historical data for atmospheric research. This work not only helps to preserve scientific heritage but also enhances the utility of historical data in contemporary research

Traiter la dysménorrhée chez les adolescentes: quand penser à l'endométriose?
No full textWhen confronted to a young girl complaining of dysmenorrhea, diagnosis is mainly based on the interrogation and clinical examination. Abdominal or transvaginal ultrasound in non-virgin adolescent is useful. Pelvic examination, pregnancy test, sexual transmitted diseases screening and Magnetic Resonance Imaging may help exclude other causes of pain. As a last resort, when medical treatment is insufficient and additional examinations negative, an exploratory laparoscopy could be proposed.
More recently, a new non-invasive diagnostic tool based on miRNA assessment in the saliva is being evaluated to avoid surgery in such young patients
Straight leg raise versus knee extension angle: which structure limits the test in asymptomatic subjects?
Full text linkpeer reviewed[en] OBJECTIVES: This study aimed to determine if the first onset of symptoms (discomfort) during the straight leg raise (SLR) (hip flexion with an extended knee) and the Knee Extension Angle (KEA) tests (knee extension with 90°of hip flexion) results from nervous or muscular structures in asymptomatic individuals. The secondary objective was to investigate if the gender influences the structure related to the discomfort.
METHODS: This cross-sectional study consisted of a single assessment session during which the structure related to participants' discomfort during the KEA and SLR was identified. For this identification, a structural differentiation (SD) was conducted during both tests using passive mobilization of the cervicothoracic spine in flexion and extension. Changes in participants' discomfort were monitored during the SD to determine whether a change or lack of change was consistent with variations in the load applied to the suspected structures either muscular or neural. If the structure related to the participants' discomfort could not be identified, two additional tests were conducted: the lateral SLR and the Slump test.
RESULTS: One hundred and seventy-eight individuals were included. Median [IQR] age was 21 years [20;23], and 57.3% were female. The structure related to participants' discomfort was similar for the SLR and the KEA (p = 0.451): neural for 72.5% of participants in the SLR and 75.8% in the KEA. Gender only influenced the structure identified in the KEA test, with a significantly higher rate of nerve-related discomfort in females than males and a significantly higher rate of muscle-related discomfort in males (p = 0.002).
CONCLUSION: In asymptomatic individuals, the discomfort induced by the SLR and the KEA tests could be related to either muscular or neural structures. Therefore, structural differentiation is necessary to identify the structure causing the discomfort in both research and clinical practice
Single-cell transcriptomics reveals inter-ethnic variation in immune response to Falciparum malaria.
Full text linkpeer reviewedAfrica's environmental, cultural, and genetic diversity can profoundly shape population responses to infectious diseases, including malaria caused by Plasmodium falciparum. Differences in malaria susceptibility among populations are documented, but the underlying mechanisms remain poorly understood. Notably, the Fulani ethnic group in Africa is less susceptible to malaria compared to other sympatric groups, such as the Mossi. They exhibit lower disease rates and parasite load as well as enhanced serological protection. However, elucidating the molecular and cellular basis of this protection has been challenging in part due to limited immunological characterization at the cellular level. To address this question, we performed single-cell transcriptomic profiling of peripheral blood mononuclear cells from 126 infected and non-infected Fulani and Mossi children in rural Burkina Faso. This analysis generated over 70,000 single-cell transcriptomes and identified 30 distinct cell subtypes. We report a profound effect of ethnicity on the transcriptional landscape, particularly within monocyte populations. Differential expression analysis across cell subtypes revealed ethnic-specific immune signatures under both infected and non-infected states. Specifically, monocytes and T cell subtypes of the Fulani exhibited reduced pro-inflammatory responses, while their B cell subtypes displayed stronger activation and inflammatory profiles. Furthermore, single-cell expression quantitative trait locus (eQTL) analysis in monocytes of infected children revealed several significant regulatory variants with ethnicity-specific effects on immune-related genes, including CD36 and MT2A. Overall, we identify ethnic, cell-type-specific, and genetic regulatory effects on host immune responses to malaria and provide valuable single-cell eQTL and transcriptomic datasets from under-represented populations
