Development Trends of Digital Transformation in Entrepreneurship and Innovation: A Bibliometric Analysis

The research provided a bibliometric analysis of 340 studies conducted between 2011 and 2022 related to digital transformation in entrepreneurship and innovation. The bibliographic data were extracted from the Scopus database and analyzed using bibliometric tools in R software. The research revealed research trends such as publication and citation per year, top sources, top authors, top documents, and top countries, as well as their impacts. The conceptual structure was analyzed using Multiple Correspondence Analysis (MCA) and hierarchical clustering analysis, which resulted in four cluster keywords related to leadership, entrepreneurial agility, technology impact, digital ecosystems, and digital services. The thematic map analysis identified twenty-seven clusters, which were mapped into four quadrants. Three of those clusters were identified as motor themes (micro foundation, digital global value chain, and digital servitization) which were analyzed in detail through content analysis. The theoretical contribution of the research is to enhance the understanding of how digital technology changes the broad assumptions on the sources, processes, and outcomes of entrepreneurial activities and innovation processes, while the practical contribution provides various contexts of technological impact.

Didymella fabae Punith.: mating type occurrence, distribution and phenotyping of the anamorph Ascochyta fabae Speg. in Tunisia.

Faba bean ascochyta blight, caused by Ascochyta fabae Speg. (teleomorph: Didymella fabae Punith.), is one of the most devastating diseases of the crop. It can cause yield losses that reach 95% in conducive weather conditions. Surveys were carried out in five regions of Tunisia: Beja, Bizerte, Jendouba, Kef and Tunis-Cap Bon. A total of 513 fungal isolates were collected from 2011 to 2013. A molecular characterization was conducted to identify the mating type of each individual using a mating type specific PCR. Results revealed that the two mating types MAT1-2 and MAT1-1 coexisted in all surveyed regions. An imbalance in favor of MAT1-2 was observed particularly in Bizerte and Jendouba regions (sex ratio was 18:85 and 32:80, respectively). Moreover, morphological and pathogenic characterization of 122 isolates among the collection revealed a significant variability in conidia type (one celled or two celled conidia) frequency, in conidia mean size and in aggressiveness toward Badii faba bean cultivar (incubation period, IP; percentage necrotic leaf area, S; and area under disease progression curve, AUDPC). A principal component analysis (PCA) performed on morphologically studied parameters (frequency of conidia cell number and conidia mean size) identified three groups of isolates based on morphological traits: one celled (1C) and two celled (2C) conidia rates, one celled and two celled conidia length and width (1L, 1W, 2L and 2W, respectively). A second PCA using aggressiveness parameters (IP: Incubation period, S1, S4 and S9: percentage of necrotic leaf area respectively 5, 20 and 45 days after inoculation) identified three distinct pathogenic groups: poorly pathogenic AG1, moderately pathogenic AG2 and highly pathogenic AG3. Morphological and pathogenic groups and mating type data were used to conduct a multiple factorial correspondence analysis (MFCA) which revealed a correlation between the variables studied. Five groups were identified, each associated with a morphological and pathogenic trait and mating type. The most pathogenic group belonged to MAT1-2 suggesting that in locations where MAT1-2 is prevalent the epidemic risk is more important.

Association of childhood adversities with psychosocial difficulties among Chinese children and adolescents.

Adverse childhood experiences (ACEs) have been well recognized as risk factors for various adverse outcomes. However, the impacts of ACEs on psychological wellbeing among Chinese children and adolescents are unknown. In total, 27 414 participants (6592 Grade 4-6 and 20 822 Grade 7-12 students) were included and information on ACEs and various psychosocial outcomes was collected. We identified subgroups with distinct psychosocial statuses using cluster analysis and logistic regression was applied to measure the associations of ACEs [individual, cumulative numbers by categories or co-occurring patterns identified by using multiple correspondence analysis (MCA)] with item- and cluster-specific psychosocial difficulties. Three and four cluster-based psychosocial statuses were identified for Grade 4-6 and Grade 7-12 students, respectively, indicating that psychosocial difficulties among younger students were mainly presented as changes in relationships/behaviours, whereas older students were more likely featured by deviations in multiple domains including psychiatric symptoms and suicidality. Strongest associations were found for threat-related ACEs (e.g. bullying experiences) with item- or cluster-based psychosocial difficulties (e.g. for cluster-based difficulties, the highest odds ratios = 1.72-2.08 for verbal bullying in Grade 4-6 students and 6.30-12.81 for cyberbullying in Grade 7-12 students). Analyses on cumulative numbers of ACEs and MCA-based ACE patterns revealed similar risk patterns. Additionally, exposure patterns predominated by poor external environment showed significant associations with psychosocial difficulties among Grade 7-12 students but not Grade 4-6 students. Chinese adolescents faced different psychosocial difficulties that varied by age, all of which were associated with ACEs, particularly threat-related ACEs. Such findings prompt the development of early interventions for those key ACEs to prevent psychosocial adversities among children and adolescents.

Cluster Analysis To Explore Clinical Subphenotypes Of Eosinophilic Granulomatosis With Polyangiitis (Churg-Strauss).

Previous studies suggested that distinct phenotypes of eosinophilic granulomatosis with polyangiitis (EGPA) could be determined by presence or absence of antineutrophil cytoplasmic antibodies (ANCA), reflecting predominant vasculitic or eosinophilic processes, respectively. This study explored whether ANCA-based clusters or other clusters can be identified in EGPA. This study used standardized data of 15 European centers for patients with EGPA fulfilling widely accepted classification criteria. We used multiple correspondence analysis, hierarchical cluster analysis, and a decision tree model. The main model included 10 clinical variables (musculoskeletal, mucocutaneous, ophthalmological, ENT, cardiovascular, pulmonary, gastrointestinal, renal, central or peripheral neurological involvement); a second model also included ANCA results. The analyses included 489 patients diagnosed in 1984-2015. ANCA were detected in 37.2% of patients, mostly P-ANCA (85.4%) and/or anti-myeloperoxidase (87.0%). Compared with ANCA-negative patients, those with ANCA had more renal (P<0.001) and peripheral neurological involvement (P=0.04), fewer cardiovascular signs (P<0.001) and fewer biopsies with eosinophilic tissue infiltrates (P=0.001). The cluster analyses generated four (model without ANCA) and five clusters (model with ANCA). Both models identified three identical clusters of 34, 39 and 40 patients according to the presence or absence of ENT, CNS and ophthalmological involvement. Peripheral neurological and cardiovascular involvement were not predictive characteristics. Although reinforcing the known association of ANCA status with clinical manifestations, cluster analysis does not support a complete separation of EGPA in ANCA-positive and -negative subsets. Collectively, these data indicate that EGPA should be regarded as a phenotypic spectrum rather than a dichotomous disease.

Statistical modelling to assessing and enhancing road traffic safety in Tripoli, Libya: A systematic approach

In recent years, there is gradual increase in the needs for private vehicle ownership in Libya due to the lack and poor public transportation infrastructure which results in the growth of road traffic accidents (RTAs), particularly in Tripoli. Therefore, in order to evaluate RTAs, the current study used a systematic method that looks at three variables: the driver, the vehicle, and urban conditions. Besides, in order to explore the causes and factors that contribute to RTAs in the city, the current study used multiple correspondence analysis and logistic regression analysis to examine the data of 1) drivers and 2) vehicles involved in accidents, and 3) RTAs reported between 2015 and 2019 on twelve major urban roads in Tripoli. The findings show that each of the 12 chosen routes had a severity index (SI) above 10 and that RTAs regularly happened on those roads. RTAs most commonly happened as a result of driver negligence, which included speeding, being careless, failing to give priority, using a phone while driving, and negotiating bends incorrectly. While the results of the logistic regression analysis showed that increasing the width of the road median, crosswalks, and pedestrian bridges as well as the number of lanes and traffic signs would significantly increase road traffic safety (RTS), by following the distinct RTA-related factors such as sign boards on each road. A reduction in RTA frequency in Tripoli might be achieved by enhancing driver education and risk perception (drivers should maintain a high degree of awareness, refrain from distractions, respect traffic rules, and modify their driving style to the conditions of the road as well as their own physical and mental health), as the majority of RTAs there are caused by speeding and inattention, and by improving the nation's road infrastructure. The current study helps to design the policy of creating and putting into practice a systematic approach for safer roads in Tripoli.

From “Bangtan Boys” to “International Relations Professor”: Mapping Self‐Identifications in the UN’s Twitter Public

Digitalization and social media established world-encompassing publics that engage with international organizations. While scholarship has analyzed how international organizations communicate with such digital publics, this article determines who participates in these publics. We created a novel dataset to map the UN’s digital public on Twitter and analyzed the bios of 243,168 accounts that have interacted with the UN. Members of this public provide self-identifications (such as researcher, consultant, or scientist) that indicate a professional interest in the UN. We analyzed clusters of users that self-identify with similar words. We find high heterogeneity in the UN’s digital public: Clusters of professional, academic, and organizational users suggest that the technocratic history of international organizations reflects in the members of its digital public. At the same time, the digital public of the UN extends to very different groups (human rights activists and K-Pop fans feature in the UN’s public on Twitter). We demonstrate for future research how multiple correspondence analysis can reveal clusters in unstructured biographical data. The article contributes the first analysis of self-identifications in digital publics of global politics.

Association of cropping practices, cropping areas, and foliar diseases of common bean (Phaseolus vulgaris L.) in Ethiopia

Common bean production is being constrained by a number of diseases. The survey was carried out to prioritize common bean diseases and their associations with cropping areas and cultural practices. A stratified random assessment on 114 farmer's fields was conducted in Ethiopia's four common bean producing zones (Metekel, Sidama, Wolaita, and Halaba). Data are collected randomly on disease severity, incidence levels, and agronomic practices. The results revealed that eleven foliar diseases were found to affect common bean production. Among them, the maximum disease severity and distribution was scored for angular leaf spot (Pseudocercospora griseola) (mean disease severity of 17.8%) and bean anthracnose (Colletotrichum lindemuthianum) (10.9%) followed by floury leaf spot (Mycovellosiella phaseoli), ascochyta blight (Ascochyta phaseolorum Sacc), and web blight (Thanatephorus cucumeris). A multiple correspondence analysis was conducted, and revealed a significant association between the diseases, cropping areas and cultural practices. Optimal crop density was found to be associated with lower bean anthracnose and mosaic virus severities, while being liked to high levels of angular leaf spot and frog-eye leaf spot. Additionally, optimum sowing dates were associated with low severities of bean anthracnose, angular leaf spot, frog-eye leaf spot, Halo Blight, and mosaic virus. On the other hand, a high weediness level was found to be associated with higher levels of web blight and bean anthracnose. Intercropping and row planting were obtained to reduce angular leaf spot and increase occurance of ascochyta blight compared to monocropping. Furthermore, row planting were found to decrease bean anthracnose, angular leaf spot, and cercospora leaf spot when compared to broadcasting. The application of fertilizer was found to decrease the occurances of bean anthracnose, halo blight, floury leaf spot, and angular leaf spot. Therefore, efforts should focus on the optimization and integration of cultural practices for managing disease and producing common bean sustainably.

Gender differences in the acceptance of wife-beating: evidence from 30 countries in Sub-Saharan Africa

BackgroundThe World Health Organization (WHO) has cited domestic violence as an urgent global maternal and child health priority. Gender differences in the acceptance of wife-beating have not been explored at the multi-country level in sub-Saharan Africa (SSA) where the occurrence of wife-beating (36%) is greater than the global average (30%). It is against this backdrop that we examine the gender differences in the acceptance of wife beating in SSA.MethodsWe used Demographic and Health Survey data from 30 SSA countries. Acceptance of wife beating among women and men was the principal outcome variable of interest. We employed Multiple correspondence analysis and logistic regression model as the primary estimation methods for this study. The descriptive statistics show that women had a higher acceptance rate (44%) of wife beating than men (25%). For the women sample, Mali, Democratic Republic of Congo, Chad, and Guinea had higher rates of acceptance of the wife beating (80.6%, 78.4%, 77.1% and 70.3% respectively) For the men, only Guinea had an acceptance rate above 50 percent.ResultsWe found that all else equal, women’s acceptance of wife beating is higher for male-headed households than for female-headed households. Women without formal education were 3.1 times more likely to accept wife beating than those with higher education. Men with no formal education were 2.3 times more likely to accept wife beating than men with higher education. We found that polygamous women were comparable to polygamous men. Polygamous women were 1.2 times more likely to accept wife beating than those in monogamous marriages. Women were 1.2 times more likely to accept wives beating if they had extramarital relationships. Contrarily, men who engaged in extramarital affairs were 1.5 times more likely to justify wife beating. We also found that women’s acceptance of wife beating decreases as they age. Men who decide on major household purchases and spending decisions on their earnings are more likely to accept wife beating. Corollary, women with similar gender and employment roles also accept wife beating. Finally, exposure to mass media is significantly associated with lower acceptance of wife beating for women and men.ConclusionWe conclude that women have a higher acceptance rate of wife beating than men in SSA. Acceptance of wife beating differs significantly by country. Given the same level of education, women are more likely to accept wife beating than men. If women and men have similar levels of employment and gender roles, acceptance of wife beating is higher when men make major household purchasing decisions and and it is still higher even when the woman makes these decisions. Acceptance of wife beating is higher among young women and men, the uneducated, those in polygamous marriages, women, and men who engage in extra marital affairs, poor households and in rural areas. The findings indicate the need for policies and programs by SSA countries to truncate the high acceptance rate of wife beating, especially among women.

“RISE AND FALL” OF THE WALRASIAN PROGRAM IN ECONOMICS: A SOCIAL AND INTELLECTUAL DYNAMICS OF THE GENERAL EQUILIBRIUM THEORY

This paper aims at understanding social practices and institutions that ensured the transnational diffusion, recognition, and renewal of the research program in the General Equilibrium Theory (GET), in spite of multiple critics and apparent theoretical dead ends. First, we trace the main conceptual developments of the Walrasian GET program since the 1950s and thus elaborate on its intellectual identity. Then, based on a systematic study of the educational and professional trajectories typical for several generations of GET scholars, we analyze a social form taken by this transnational and multidisciplinary “scientific community”: an institutional dynamics of the Walrasian GET program, most common career patterns, and the forms of international and intergenerational transmission. We construct a database of GET theorists and apply to this dataset a technique of Multiple Correspondence Analysis (MCA) in order to investigate the relational patterns between attribution of scientific credit (symbolic capital) and biographical properties in a transnational space of the GET scholars.

Survey on public acceptance of insects as novel food in a non-EU country: a case study of Serbia

Abstract The present study aimed to evaluate the state of public perceptions and acceptance of insects as food in Serbia. The data was gathered via an online survey involving 1102 participants who completed Google Forms questionnaire shared through mailing lists and social media channels. The findings indicate that, while 85.3% of the respondents were aware of the use of insects in human diet, only 12.5% had previously consumed edible insects. The results of the chi-square tests further revealed that both familiarity and experience significantly affected willingness to buy insect-based food, whereas age and educational level did not. Men were more open to purchasing edible insects than women. Twice as many participants (49.4%) responded positively to eating insect-based food in which insects were not visible than to consuming recognisable insects (25.4%). Crisis (shortage of conventional sources of protein), curiosity, nutrition, and health benefits were the most frequently chosen reasons for including insect-based products in a diet, whereas disgust was the main reason against. Multiple correspondence analysis resulted in two dimensions that accounted for the largest amount of variance. The first dimension referred to familiarity with entomophagy, experience of eating edible insects, and willingness to buy insect-based products, whereby sustainability, affordability, taste, nutrition, and curiosity were the reasons for including insect-based products in a diet, while high price was a reason against. The second dimension indicated lack of familiarity, experience, or willingness to buy, with crisis as the most common motivating reason, and the perception of insects as pests and socio-cultural unacceptance as the main reasons against. Although almost half of the respondents reported willingness to consume processed insect-based products, the actual acceptance is possibly lower. Therefore, future research should focus on the provision of tasting opportunities as well as information on the benefits associated with the production and consumption of insects.

Is there a generational shift in preferences for forest carbon sequestration vs. preservation of agricultural landscapes?

Afforestation and reforestation are considered important measures for climate change mitigation. Because the land area available for tree planting may serve multiple purposes, striking the right balance between climate goals and other objectives is crucial. We conducted a survey of the Norwegian population to investigate potential land-use conflicts that may arise from executing a large-scale afforestation programme. Respondents were presented with three land-use alternatives to replace formerly grazed agricultural land. We used manipulated landscape photos to elicit their underlying value orientations. We combined multiple correspondence analysis with latent class regression models to reveal preference heterogeneity. Our models grouped respondents into three latent classes, with 24%, 24% and 52%, respectively, expressing a preference for forest carbon sequestration, recreation or agriculture as the most crucial land-use function to be retained. Birth year emerged as a strong predictor of class membership. Specifically, generations born before 1970 were more inclined to support the continuation of agricultural landscapes, while those born in 1980 and later showed a stronger inclination towards natural forest succession for carbon sequestration or recreational purposes. Quantitatively, every 10-year reduction in age increased the odds of a respondent belonging to the forestation or recreation class (relative to the agricultural class) by a factor of 2. Interestingly, even among respondents who were classified as most climate concerned, natural forests were 50% more likely to be preferred over monoculture spruce plantation as a policy option. This suggests that there may be public resistance to spruce planting for climate mitigation purposes in Norway.

Asset accumulation, financial inclusion and subjective well‐being: The role of financial formality in South Africa's households

AbstractAsset building and financial inclusion programmes have contributed to the enhancement of consumers' welfare through asset accumulation. Employing the FinScope consumer survey for South Africa, we extended the analysis of the relationship between financial inclusion and asset holding by examining whether this, in turn, improves consumers' subjective well‐being (SWB). Financial inclusion was captured by credit, savings, and insurance whereas multiple correspondence analysis was employed to compute an asset index that captured indicators of individual material possessions. Results from the partial least squares path model suggested that financial inclusion had an indirect positive association with consumers' SWB through increased asset holding, but the association was more pronounced via formal channels of saving, credit, and insurance. As such, social policymakers are encouraged to integrate access to insurance, credit, and savings through formal channels in poverty interventions since this has a greater indirect association with consumers' SWB via increased asset ownership.

Factors associated with exclusive breastfeeding of children under six months of age in Cote d’Ivoire

BackgroundDespite benefits of exclusive breastfeeding (EBF) and its strategic place in the national guidelines for infant and young child feeding, its practice remains insufficient in Cote d’Ivoire. It is therefore important to identify its early stopping associated factors. We aimed to (i) assess the extent of children’s exposure to exclusive breastfeeding and the associated explanatory factors for discontinuation before six months, and (ii) to profile non-exclusively breastfed children and interrelationships between these factors.MethodsA secondary analysis of data from the 2016 Cote d’Ivoire Fifth Multi Indicator Cluster Survey (MICS5) of 980 children under six months of age was conducted in this study. Data were analyzed using the actuarial method of survival hazard estimation combined with the Wilcoxon (Gehan) test, discrete time proportional hazards regression models, and Multiple Correspondence Analysis (MCA) to profile the children.ResultsMaternal exposure to counseling session, age at delivery, and child sex were significantly associated with the likelihood of discontinuing exclusive breastfeeding before the first six months of life. Children deprived of EBF resided in urban areas, in high and very high economic welfare households. Their mothers had a secondary education or higher and had three or fewer children.Logistic analysis showed that health status and sex of the child were significantly associated (P < 0.001) with exclusive breastfeeding. An extremely important and rarely studied factor is that children who were sick in weeks prior to the survey were more likely to remain exclusive breastfeeding (adjusted OR 1.80; 95% Confidence Interval (CI) 1.452, 2.234). Girls are less likely to be exclusively breastfed than boys (adjusted OR 1.48; 95% CI 1.22, 1.798). Low standard of living was associated with early cessation of EBF (adjusted OR 2.15; CI 1.325, 3.499). The duration of the exclusive breastfeeding was significantly longer among mothers with high exposure to medical discourse (adjusted OR 0.74; CI 0.595, 0.91).ConclusionsImproving the practice of exclusive breastfeeding in Cote d’Ivoire requires strengthening the capacities of health professionals in terms of advice and assistance to mothers for the practice of exclusive breastfeeding and its maintenance until six months of age, regardless of the health status and sex of the child.

The Relationship Between Satisfaction and Conventional and Alternative Characteristics of Organizations

In this quantitative study, through Multiple Correspondence Analysis, we explored the existence of a statistically significant association between conventional and alternative organizational characteristics and the attribution of satisfaction or dissatisfaction at work. The study had 172 respondents participating in an online survey. The results indicate that all characteristics of conventional organizations, to a greater or lesser extent, were associated with the perception of dissatisfaction, whereas characteristics of alternative organizations, in the same way, were associated with satisfaction. Four dimensions of comparison between conventional and alternative organizational modes stood out in terms of contribution and relevance, namely: i) technical orientation (efficiency versus conviviality); ii) economic orientation (growth versus sufficiency); iii) commercial orientation (market versus community); and iv) inter-organizational orientation competition vers(us cooperation). The results, specifically, show that the technical orientation toward productive efficiency, as well as the commercial orientation toward the market, is, at a strong level, associated with dissatisfaction, while the cooperative inter-organizational orientation is strongly associated with satisfaction. The investigation sheds light on a better understanding of organizational modes that oppose the dominant conventional logic.

Association of haemolysis markers, blood viscosity and microcirculation function with organ damage in sickle cell disease in sub-Saharan Africa (the BIOCADRE study).

Sickle cell anaemia (SCA) is a monogenic disease with a highly variable clinical course. We aimed to investigate associations between microvascular function, haemolysis markers, blood viscosity and various types of SCA-related organ damage in a multicentric sub-Saharan African cohort of patients with SCA. In a cross-sectional study, we selected seven groups of adult patients with SS phenotype in Dakar and Bamako based on the following complications: leg ulcer, priapism, osteonecrosis, retinopathy, high tricuspid regurgitant jet velocity (TRV), macro-albuminuria or none. Clinical assessment, echocardiography, peripheral arterial tonometry, laboratory tests and blood viscosity measurement were performed. We explored statistical associations between the biological parameters and the six studied complications. Among 235 patients, 58 had high TRV, 46 osteonecrosis, 43 priapism, 33 leg ulcers, 31 retinopathy and 22 macroalbuminuria, whereas 36 had none of these complications. Multiple correspondence analysis revealed no cluster of complications. Lactate dehydrogenase levels were associated with high TRV, and blood viscosity was associated with retinopathy and the absence of macroalbuminuria. Despite extensive phenotyping of patients, no specific pattern of SCA-related complications was identified. New biomarkers are needed to predict SCA clinical expression to adapt patient management, especially in Africa, where healthcare resources are scarce.

Variables fordifferential diagnosis offamilial Mediterranean fever: Multiple correspondence analysis ofa large Japanese cohort.

We investigated differential diagnoses that should be noted with familial Mediterranean fever (FMF) and useful variables for differentiation in a large Japanese cohort. Patients aged ≥13 years who were clinically suspected of having FMF by Livneh criteria were studied 1 year after MEFV genetic testing. Patients ultimately diagnosed with other diseases were studied, and the association among each disease, patient characteristics, and clinical variables were analysed using multiple correspondence analysis. In total, 504 patients were included in this study; 34 (6.7%) were diagnosed with a disease other than FMF. The most common diagnosis was Behçet's disease, followed by periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome, inflammatory bowel disease, myelodysplastic syndromes (MDS), and infectious diseases. Although none of the non-FMF patients had exon 10 variants, some responded to colchicine treatment. Multiple correspondence analysis suggested that atypical symptoms such as stomatitis were associated with Behçet's disease and PFAPA syndrome, whereas characteristic situations such as disease onset ≥40 years were associated with MDS and infectious diseases. Careful follow-ups and reanalysis of the diagnosis should be performed for patients with atypical findings and no exon 10 variants, even if their symptoms meet the clinical criteria for FMF.

Seasonality of acute kidney injury phenotypes in England: an unsupervised machine learning classification study of electronic health records

BackgroundAcute Kidney Injury (AKI) is a multifactorial condition which presents a substantial burden to healthcare systems. There is limited evidence on whether it is seasonal. We sought to investigate the seasonality of AKI hospitalisations in England and use unsupervised machine learning to explore clustering of underlying comorbidities, to gain insights for future intervention.MethodsWe used Hospital Episodes Statistics linked to the Clinical Practice Research Datalink to describe the overall incidence of AKI admissions between 2015 and 2019 weekly by demographic and admission characteristics. We carried out dimension reduction on 850 diagnosis codes using multiple correspondence analysis and applied k-means clustering to classify patients. We phenotype each group based on the dominant characteristics and describe the seasonality of AKI admissions by these different phenotypes.ResultsBetween 2015 and 2019, weekly AKI admissions peaked in winter, with additional summer peaks related to periods of extreme heat. Winter seasonality was more evident in those diagnosed with AKI on admission. From the cluster classification we describe six phenotypes of people admitted to hospital with AKI. Among these, seasonality of AKI admissions was observed among people who we described as having a multimorbid phenotype, established risk factor phenotype, and general AKI phenotype.ConclusionWe demonstrate winter seasonality of AKI admissions in England, particularly among those with AKI diagnosed on admission, suggestive of community triggers. Differences in seasonality between phenotypes suggests some groups may be more likely to develop AKI as a result of these factors. This may be driven by underlying comorbidity profiles or reflect differences in uptake of seasonal interventions such as vaccines.

Recognition of emotion and pain by owners benefits the welfare of donkeys in a challenging working environment.

Working donkeys (Equus asinus) support human living standards globally. However, there is little information on the effect of human perceptions of emotion and pain on the welfare of working donkeys. We interviewed donkey owners (n=332) in Pakistan to determine the relationship between human perspectives on donkey sentience: emotions and the ability to feel pain, and the routine working practices that could impact donkey welfare. The majority of donkey owners used padding under the saddle (n=211; 63.6%; 95% CI (58.3%-68.9%)) and provided access to food (n=213; 64.2%; 95% CI (58.9%-69.3%)) and water (n=195; 58.7%; 95% CI (53.4%-64.1%)) during the working day. Owners reported that at some point in their donkey's life, 65.3% (95% CI (60.2%-70.5%)) had load-associated injuries, of which 27.7% (n=92; 95% CI (22.8%-32.5%)) were wounds, 20.5% (n=68; 95% CI (16.1%-24.8%)) were lameness and 7.2% (n=24; 95% CI 4.4%-10.0%) were back pain. In total, 81.3% (95% CI 77.1%-85.5%; n=270) of owners believed that their donkeys felt pain, and 70.2% (95% CI (65.2%-75.1%; n=233) of owners believed that their donkeys had emotions. Multiple correspondence analysis (MCA) was used to understand the relationship between owners' recognition of emotions and pain in donkeys and their working practices. The MCA factor map revealed two clusters, named positive and negative clusters. The positive cluster included owner's recognition of donkey pain and emotions, the availability of food and water, use of padding under the saddle, absence of injuries along with the willingness to follow loading guidelines. The negative cluster represented practices that did not benefit donkey welfare, such as using saddles without padding and a lack of food and water during work. The presence of injuries, owners not recognizing that donkeys feel pain and emotion along with an unwillingness to follow loading guidelines were also found in the negative cluster. We show that the owners who recognized sentience in their donkeys were more likely to use practices that are good for donkey welfare. The ability of owners to identify sentience in donkeys, along with their willingness to follow welfare guidelines, are important factors in improving the lives of working donkeys.

A bourdieusian analysis of vaccine hesitancy. The case of Italian upper secondary school students

ABSTRACT The aim of this paper is to propose an original analysis of the association between social status and attitudes toward Covid-19 vaccines regarding upper-secondary students in Italy. The research was conducted by administering an online survey on a probabilistic and stratified sample of 5,699 students, in the spring of 2021, when the vaccination campaign in Italy had been underway for only a few months. Following the bourdieusian perspective, we have used a multiple correspondence analysis to examine the polarization between pro-vaccine and anti-vaccine groups as the clash of stances that agents take in accordance with their position in the cultural field. Our results suggest that the construction of a negative school experience by the subordinate classes is the source of a lack of social recognition in the cultural field, which feeds an aversion to everything the main institutions in this field recommend should be done.

Use of multiple correspondence analysis to explore associations between caregivers and sun protective habits during summer vacations.

Childhood exposure to ultraviolet radiation (UVR) plays an important role in the development of keratinocyte carcinomas and melanomas. Therefore, sun protective measures ought to be implemented during early childhood. Young children are largely dependent upon adult care providers in order to achieve proper sun protection. To develop effective photoprotection in children, it is necessary to understand caregivers' attitudes and knowledge about UVR exposure. This study aimed to explore the variables associated with sun protective behaviour in parents and grandparents during summer vacations. A multinational, cross-sectional study was conducted using a web-based online survey with a representative sample of parents and grandparents of children aged ≤ 12 years, who cared for their children/grandchildren for at least 2 weeks during the summer of 2021, in five countries (France, Germany, Spain, Italy and the USA). Multiple correspondence analysis (MCA) was used to explore in an unbiased way the possible relationships among all the variables and to identify specific profiles. A total of 6190 adult participants responded to the questionnaire: 5104 parents (average age 42.0 years, 54.3% women) and 1086 grandparents (average age 64.2 years, 55.5% women). MCA allowed discrimination of two groups of respondents based on their answers: a profile with 'unprotected sun exposure habits' vs. those with 'protective sun exposure habits'. Parents fell in closer proximity to the 'unprotected sun exposure habits', and 'sunburn reported in youngest child'. Grandparents adopted more cautious behaviours than parents. Nevertheless, grandparents fell in proximity to 'having exposed the grandchild to the sun between 11 h and 17.00 h', 'not using an umbrella' and 'not using sunglasses'. Although grandparents appear to adopt more cautious behaviours than parents, many gaps in proper sun protection behaviour were observed in both groups of caregivers.
