How Wood Fuels\u2019 Quality Relates to the Standards: A Class-Modelling Approach

The quality requirements of wood biofuels are regulated by a series of harmonized international standards. These standards define the technical parameter limits that influence the quality of solid biomass as a fuel. In 2014 the European reference standard for solid biofuel was replaced by the International ISO standard. In the case of wood chips, the main difference between the European and International standards is the definition of particle size distribution classes. In this context, this study analyses the quality of wood chips and its variation over the years according to the \u201cformer\u201d (EN 14691-4) and \u201cin force\u201d (ISO 17225-4) standards. A Soft Independent Modelling of Class Analogy (SIMCA) model was built to predict the best quality of wood chips and to clarify the relationship between quality and standard parameters, time and changes in the standard regulations. The results show that, compared to the EN standards, classification with the ISO standards increases the samples belonging to the best quality classes and decreases the not classified samples. Furthermore, all the SIMCA models have a high sensitivity (>90%), reflect the differences introduced to the quality standards and are therefore suitable for monitoring the quality of wood chips and their changes

Social capital in chronic disease: an ethnographic study

Chronically ill conditions are particularly difficult to manage because of their impact both on the social and on the corporal sphere to such an extent as to involve a series of problems that negatively alter the quality of life of affected patients. Chronicity has also a considerable ef-fect on social capital. In the current literature, it is known that social capital may contribute to a range of advantages to people health. Chronic Venous Disease (CVD) includes several pathologi-cal alterations of the venous system of the lower limbs that cause a wide range of symptoms and signs. The aim of this study is to explore, with a qualitative approach, the dynamics of social cap-ital within people's experience of CVD and describe the roles of family and friends and the health care system. The method used is based on face-to-face semistructured interviews was performed, following the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist. Six-teen patients were included: 11 women and 5 men. The results obtained are completely in line with the current literature, which shows a certain difficulty in terms of daily activities, pain management; work-related difficulties; non-coverage of healthcare costs for medications and drugs prescribed. In the context of social capital, the bonding social capital of the patients inter-viewed was more positively perceived in the role of CVD management than by the patients' fami-lies. Another interesting result concerns the total absence of knowledge of patient associations with CVD. Thus, alongside the biographical destruction that CVD entails, there is evidence of the scarce relevance and presence of health policies capable of improving the quality of life of these people not only from a social and medical point of view but also from an economic point of vie

Leveraging online selling through social media influencers

Shuqair, S., Filieri, R., Viglia, G., Mattila, A. S., & Pinto, D. C. (2024). Leveraging online selling through social media influencers. Journal of Business Research, 171(January), 1-10. [114391]. https://doi.org/10.1016/j.jbusres.2023.114391While prior research suggests that facial expression influences consumer behavior, it remains unclear under which conditions specific emotional expressions on social media drive sales performance and customer engagement. Drawing on the facial feedback hypothesis and the emotional congruence framework, two pre-registered experimental studies (N = 995) demonstrate that the fit between facial expressions (broad vs. slight smile) and endorsement type (hedonic vs. utilitarian) influence engagement and consumers’ purchase intents. Findings indicate that broad (vs. slight) smiles are more likely to enhance consumer responses when paired with hedonic endorsements driven by emotional contagion. Conversely, slight smiles are equally suited for both types of endorsements and do not foster emotional contagion. The findings offer actionable insights for maximizing consumer engagement and purchase intents within social media marketing efforts.publishersversionepub_ahead_of_prin

Auditory predictions shape the neural responses to stimulus repetition and sensory change

Perception is a highly active process relying on the continuous formulation of predictive inferences using short-term sensory memory templates, which are recursively adjusted based on new input. According to this idea, earlier studies have shown that novel stimuli preceded by a higher number of repetitions yield greater novelty responses, indexed by larger mismatch negativity (MMN). However, it is not clear whether this MMN memory trace effect is driven by more adapted responses to prior stimulation or rather by a heightened processing of the unexpected deviant, and only few studies have so far attempted to characterize the functional neuroanatomy of these effects. Here we implemented a modified version of the auditory frequency oddball paradigm that enables modeling the responses to both repeated standard and deviant stimuli. Fifteen subjects underwent functional magnetic resonance imaging (fMRI) while their attention was diverted from auditory stimulation. We found that deviants with longer stimulus history of standard repetitions yielded a more robust and widespread activation in the bilateral auditory cortex. Standard tones repetition yielded a pattern of response entangling both suppression and enhancement effects depending on the predictability of upcoming stimuli. We also observed that regularity encoding and deviance detection mapped onto spatially segregated cortical subfields. Our data provide a better understanding of the neural representations underlying auditory repetition and deviance detection effects, and further support that perception operates through the principles of Bayesian predictive coding

Using a system thinking approach to assess the contribution of nature based solutions to sustainable development goals

Abstract Climate change and the overexploitation of natural resources increase the need to integrate sustainable development policies at both national and international levels to fit the demands of a growing population. In 2015 the United Nations (UN) established the 2030 Agenda for sustainable development with the aim of eradicating extreme poverty, reducing inequality and protecting the planet. The Agenda 2030 highlights the importance of biodiversity and the functioning of ecosystems to maintain economic activities and the well-being of local communities. Nature Based Solutions (NBS) support biodiversity conservation and the functioning of ecosystems. NBS are increasingly seen as innovative solutions to manage water-related risks while transforming natural capital into a source of green growth and sustainable development. In this context, NBS could potentially contribute to the achievement of several Sustainable Development Goals (SDGs) by promoting the delivery of bundles of ecosystem services together generating various social, economic and environmental co-benefits. However, to achieve the full potential of NBS, it is necessary to recognize the trade-offs and synergies of the co-benefits associated with their implementation. To this aim, we have adopted a system perspective and a multi-sectoral approach to analyse the potential of NBS to deliver co-benefits while at the same time reducing the negative effects of water-related hazards. Using the case study of Copenhagen, we have analysed the relationships between the co-benefits associated with the scenario of the restoration of the Ladegaardsaa urban river. Our hypothesis is that enhancing the understanding of the social, economic and environmental factors of the system, including mutual influences and trade-offs, could improve the decision-making process and thereby enhance the capability of NBS to contribute to the achievement of the SDGs

Minimal disease activity in patients with psoriatic arthritis treated with ustekinumab: results from a 24-week real-world study

Psoriatic arthritis (PsA) is a chronic inflammatory joint disease affecting around 40% of psoriasis patients. Minimal disease activity (MDA) criteria have been proposed to identify a state of low disease activity, one of the principal goals of treatment for psoriatic disease. This study investigated treatment with ustekinumab (UST) in the context of a real-world setting. Thirty-four PsA patients who had failure or inadequate response to conventional synthetic disease-modifying antirheumatic drugs or to anti-tumour necrosis factor alpha were enrolled. Demographic and clinical features, MDA criteria, and the impact of psoriatic skin manifestations on patients' quality of life (QoL) using the dermatology life quality index (DLQI) questionnaire were evaluated at baseline and after 24-week treatment. Adverse events were recorded. At week 24, 70.5% of patients (n = 24) achieved MDA. A sub-analysis of dermatological indices of the MDA criteria showed that the psoriasis area severity index score was significantly improved and body surface area was significantly decreased at 24 weeks compared with that at baseline (both p < 0.001). For the rheumatologic indexes, tender joint count, swollen joint count, and tender entheseal points were all significantly improved at 24 weeks of therapy (all p < 0.01 vs. baseline). Mean DLQI value decreased approximately fourfold, and there were no safety concerns. The achievement of MDA as well as the significant improvement in DLQI and lack of adverse events in the context of a real-life setting shown here confirms the efficacy and safety of UST in PsA

Extruded snacks enriched with açaí berry: physicochemical properties and bioactive constituents

This work aimed to develop extrudates enriched with açaí and evaluate the effect of this fruit on their physicochemical properties and bioactive constituents of these foods. Rice/corn (2 : 1) extrudates containing 0, 2, 4, and 6% of freeze-dried açaí were prepared using a twin-screw extruder and characterized towards proximate composition, the concentration of anthocyanin and carotenoids, and typical process-related extrudate characteristics. The addition of açaí increased the total anthocyanins (from 0 to 20.1 mg 100 g-1) and total carotenoid content (from 1.6 to 6.2 μg g-1). Açaí enrichment elevated the protein and mineral content by 6.3% and 32.2%, respectively. There was no significant difference between the samples regarding the expansion index. Higher incorporation of açaí resulted in crispier snacks extrudates and high total color difference (ΔE). Therefore, açaí (up to 6%) can be regarded as stable in the extrusion conditions applied and be used in extrudates to enhance their bioactive and nutritional properties, providing color and suitable physical characteristics. Açaí extrudates can serve as an alternative for consumers interested in convenience food with bioactive constituents

Association between Anthropometric Measurements and Vascular Disease: A Cross Sectional Study

The aim of this article is to assess the most studied anthropometric measurements in a population of patients with vascular disease (VD) such as chronic venous disease (CVD), carotid stenosis (CS), abdominal aortic aneurysm (AAA), and peripheral artery disease (PAD). This is a cross sectional study that recruited consecutive patients with VD (CVD, CS, AAA, PAD) referred to Vascular Surgery Units of two hospitals in the period July 2019–March 2022. Several anthropometric measurements such as height, weight, body mass index (BMI), waist circumference, waist-to-BMI, waist-to-hip ratio (WHR), A Body Shape Index (ABSI), waist-to-stature ratio (WSR) were recorded. In a one-way ANOVA test, no statistical significance for all anthropometric variables were found, but the post hoc analysis performed with Tuckey test, show significant difference for height (p-value: 0.017) and WHR (p-value: 0.005) when compared AAA and CS groups with CVD, respectively. Height seems positively associated with AAA, and negatively associated with CVD. WHR seems positively associated with CS and negatively associated with CVD. Further studies are needed to clarify the role of anthropometric measures as independent predictors for vascular disease onset, progression, and response to treatments

Molecular Determinants of Chronic Venous Disease: A Comprehensive Review

Chronic Venous Disease (CVD) refers to several pathological and hemodynamic alterations of the veins of lower limbs causing a wide range of symptoms and signs with a high prevalence in the general population and with disabling consequences in the most severe forms. The etiology and pathophysiology of CVD is complex and multifactorial, involving genetic, proteomic, and cellular mechanisms that result in changes to the venous structure and functions. Expressions of several genes associated with angiogenesis, vascular development, and the regulation of veins are responsible for the susceptibility to CVD. Current evidence shows that several extracellular matrix alterations (ECM) could be identified and in some cases pharmacologically targeted. This review shows the most up to date information on molecular determinants of CVD in order to provide a complete overview of the current knowledge on this topic. In particular, the article explores the genetic influence, the hormonal influence, ECM imbalance, and histopathology of CVD and the role of endothelial dysfunction in CVD
