Adding ethnicity to cardiovascular risk prediction: external validation and model updating of SCORE2 using data from the multiethnic HELIUS population cohort

Abstract Background Current prediction models for mainland Europe do not include ethnicity, despite ethnic disparities in cardiovascular disease (CVD) risk. Purpose We evaluated the performance of SCORE2 across the largest ethnic groups in the Netherlands with and without the factor of ethnicity. Methods We linked data from 11,614 participants enrolled between 2011 and 2015 in the prospective, multi-ethnic HELIUS cohort study, the Netherlands, aged between 40 and 70 years without CVD with hospital data. Variables (age, sex, smoking status, blood pressure, cholesterol) and outcome first CVD event (myocardial infarction, stroke, CVD death) were consistent with SCORE2. We used Fine and Gray models to calculate sub-distribution hazard ratios (SHR) for South-Asian Surinamese, African Surinamese, Ghanaian, Turkish and Moroccan origin groups, relative to the Dutch origin group, on top of individual SCORE2 risk predictions. Model performance was evaluated by discrimination, calibration and net reclassification index (NRI). Results Overall, 274 fatal and non-fatal CVD events, and 146 non-cardiovascular deaths were observed during a median of 7.8 years follow-up (IQR 6.8–8.8). SHRs for CVD events were 1.86 (95% CI 1.31-2.65, p=0.0005) for the South-Asian Surinamese, 1.09 (95% CI 0.76-1.56) for the African-Surinamese, 1.48 (95% CI 0.94-2.31) for the Ghanaian, 1.63 (95% CI 1.09-2.44, p=0.018) for the Turkish, and 0.67 (95% CI 0.39-1.18) for the Moroccan origin groups. Adding ethnicity to SCORE2 led to comparable calibration and discrimination [0.76 (0.74-0.79) vs. 0.77 (95% CI 0.74-0.78)]. The NRI for adding ethnicity to SCORE2 was 0.24 (95% CI 0.18-0.31) for events and -0.12 (95% CI -0.13--0.12) for non-events. Conclusion Adding ethnic backgrounds improves risk classification of the SCORE2 risk prediction model in a middle-aged, multi-ethnic Dutch population, which may help to address disparities in CVDs through timely treatment.

Monitoring spatiotemporal patterns in the genetic diversity of a European butterfly species

Abstract The importance of genetic diversity has been recognised by the Convention on Biological Diversity but attempts at monitoring or improving the genetic diversity of populations have been minimal. Here, we investigate changes over time in the genetic diversity of a wild insect species, Maniola jurtina (Lepidoptera: Nymphalidae) and present a large‐scale investigation into contemporary spatial genetic diversity. Using microsatellite markers, we calculate multiple measures of genetic diversity and divergence for M. jurtina populations over 8 years in the UK and compare these findings with long‐term abundance trends. We also conduct a large‐scale spatial analysis into the genetic diversity and population structuring of M. jurtina across Europe. All UK populations sampled have high levels of gene flow and genetic diversity, with genetic diversity stable over time. Across Europe, we find some population structuring between populations in the UK and the European mainland, suggesting restricted geneflow between the two regions. The monitoring of a wild species' genetic diversity is an achievable aim, and one that could be carried out for many species, particularly Lepidoptera. Future approaches may aim to develop higher resolution genetic markers and cover a wider range of species. The use of abundance data offers additional insight, and we find that concurrent, dedicated genetic monitoring can provide effective tracking of biodiversity trends.

Phenology of the spruce bark beetle Ips typographus in the UK under past, current and future climate conditions

Summary The European spruce bark‐beetle, Ips typographus, is a major pest of Norway spruce across mainland Europe; however, until 2018, it was considered absent from the United Kingdom (UK). The finding of a breeding population of I. typographus in Kent, England, in 2018 and subsequent findings in pheromone traps across the southeast of England, has led to an urgent need to improve understanding of environmental suitability across the UK. Two distinct published phenological models for I. typographus, developed in Sweden and Austria, were adapted for use in the UK and validated against pheromone trap data collected at the original site of infestation and in the surrounding area from 2019 to 2022. Both models captured some, but not all, of the within‐season variation in trap catches. One, the PHENIPS model, more accurately captured early season flight patterns. The climate in the southeast of England is mild enough to facilitate two generations of the beetle, while further north the pest is expected to be univoltine. At high altitude in Scotland, there is insufficient thermal warming within a season for the completion of one annual generation. Phenological modelling does not explain why the pest failed to establish in England prior to 2018 including when a large amount of infested material was imported to sawmills in the 1940s. Under 2 and 3°C global warming scenarios, we might expect to see an increase in potential voltinism across the UK in the next few decades, increasing the risk of large outbreaks of I. typographus were it allowed to establish. Societal impact statementIn 2018, a breeding population of the European spruce bark‐beetle, Ips typographus, was discovered in woodland in southeast England. Ips typographus is a major forest pest in continental Europe; however, despite previous findings at ports and sawmills, this was the first recorded infestation in the UK. The number of generations per year (voltinism) varies with latitude and altitude. Applying a phenological model, we find that the current climate in southern UK could support two generations, while temperature accumulation in parts of Scotland may be insufficient to support one generation. Global warming will increase voltinism and hence the risk of establishment.

English as a lingua franca discourse in European Union higher education and research policy

The use of English as lingua franca in mainland Europe’s higher education and research sectors has rapidly expanded over the past several decades. Despite these expansions, critics claim that there is a conspicuous absence of European Union (EU) language policy concerned with the use of English as a “contact” language in education and research contexts. This study attempts to assess these claims by conducting a comparative analysis of English as a lingua franca discourse in the policy declarations and communications of two EU actors with remits for higher education and research – the European Higher Education Area (EHEA) and the European Research Area (ERA). Using methods that draw on critical discourse analysis and corpus linguistics, I compiled specialised corpora consisting of the policy documents published by the EHEA and the ERA over the past twenty years. I then used the corpus analysis tool Sketch Engine and a reference corpus of general EU discourse to assess how often and in what ways language policy was considered. The analysis reveals intra-institutional conflicts in how language is conceptualised between policy actors and across policy portfolios in the EU. The findings also confirm the absence of explicit discourse on the use of English in academic and research contexts over the institutional lifetimes of two actors with remits for these sectors. The study highlights the persistence of a “top-down/bottom-up” conceptual gap at the heart of EU language policymaking regarding English as a lingua franca in European higher education and research.

HEMATOLOGY AND BIOCHEMISTRY REFERENCE VALUES IN NESTLING RED KITES (MILVUS MILVUS) IN SHORT-TERM HUMAN CARE IN ENGLAND.

Between the years 2022 and 2023, 62 red kite (Milvus milvus) nestlings were translocated from England to Spain to bolster declining populations in mainland Europe as part of a wider conservation initiative. Health examinations were undertaken by veterinarians ahead of translocation, including examination of hematology and biochemistry parameters from blood samples. This study aimed to establish reference values for these parameters in nestling red kites for use in future translocations or for other clinical purposes. All individuals included in the analysis were clinically healthy at the time of sampling. Biochemical reference intervals were comparable to published values for other Accipitridae, although differences in hematology were noted: PCV was generally lower; and WBC counts higher than (up to triple) those reported for related species of a similar age. It is hypothesized that these differences reflect species variations or the effects of the stress of recent capture on the immune system of the red kites. A Leucocytozoon species was identified on blood smears of six of the red kites. The reference intervals presented in this study are representative of free-living red kite nestlings in England that have recently been captured for conservation translocation purposes.

Assessment of river ecological status in the French West Indies based on diatom flora

The Water Framework Directive (WFD) requires member states to routinely assess the river ecological status using community-based indices. However, there is still a lack of published WFD-compliant methods for the French West Indies, especially using diatom-based indices. Martinique and Guadeloupe exhibit diverse landscapes shaped by their complex geological history and tropical climatic conditions. These strong particularities make the existing indices developed for the European mainland unusable. Based on diatom sampling from to 2013 (607 samples) and through multivariate analyses, we developed the Indice Diatomique des Antilles (IDA). We first identified the key abiotic factors influencing diatom communities on both islands, and then characterized taxon sensitivity by considering their presence probability along a pressure gradient.. The index was based on the presence and relative abundance of these taxa in each sample. The last step consisted of using new data from the 2014–2022 sampling surveys (457 samples) as a validation dataset to verify IDA accuracy. Our results suggest that the IDA methodology is well designed to assess the ecological status of rivers in the West Indies.

Research on teachers of colour and minoritised teachers in majoritarian education systems: A scoping review of the literature in the last two decades

AbstractThe world map is changing due to waves of immigration, population and demographic changes in mainland Europe and North America. There is a growing need for a more diverse teacher workforce to close the racial and ethnic gap between students and teachers in populations with high diversity. The scholarship discussing integration challenges facing teachers of colour and minority teachers in majoritarian education systems has yet to be exhaustively analysed and synthesised. Moreover, the literature remains fragmented despite numerous studies emphasising the significance of supporting teachers of colour and minority teachers to ensure equity and inclusiveness in majoritarian education systems to better represent the student body. This study reviews the literature through a bibliometric analysis of 387 peer‐reviewed papers on this topic published between 2000 and 2024, followed by a synthesis of the top‐cited papers. First, we emphasised the importance of researching the integration of minority teachers and teachers of colour to understand their contribution to students' thriving and the transformation of education systems towards diversity and inclusion. The quantitative analysis is followed by a systematic qualitative synthesis of the top 18 cited papers. The results highlighted that most research on minority teachers and teachers of colour is from the United States and the United Kingdom. They also highlighted the necessity of revisiting curriculums and enhancing relationships with children to raise awareness about issues of systemic racism, cultural responsiveness and deeper inclusion. Recommendations emphasise addressing systemic racism and enhancing cultural responsiveness. These findings can guide future research, policies and practices to support minority teachers' integration and better represent student diversity. Context and implicationsRationale for this studyThe world map is changing due to waves of immigration, population shift, and demographic changes, highlighting the growing need for a more diverse teaching workforce to close the racial and ethnic gaps between students and teachers in highly diverse populations. However, the scholarship discussing the integration challenges faced by teachers of colour and minority teachers in majoritarian education systems remains fragmented and has yet to be exhaustively analysed and synthesised. Therefore, this paper presents a mixed‐methods systematic review of recent international evidence on the integration of minority teachers and teachers of colour in majoritarian education systems worldwide.Why the new findings matterThis research contributes to further insights in the scholarship foci, including identifying several research gaps related to the integration of teachers of colour and minority teachers. Our findings can inform future policies by enhancing understanding of the unique needs and challenges faced by minoritised teachers within various political, social and educational contexts. This knowledge can guide the training, recruitment, mentoring and retention of minority teachers. Additionally, further comparative research on this topic is necessary to enrich knowledge and contribute to diverse models for preparing, recruiting and retaining teachers of colour, thereby enhancing diversity in schools and fostering the success of minority students. Therefore, this study not only enriches our understanding of the current state of research but also sets the stage for future inquiries that could inform more nuanced and effective educational policies and practices worldwide.Implications for educational researchers and policy makersOur research findings offer valuable insights for scholars, policy makers, superintendents and school principals who are committed to conducting future empirical research, systematic reviews or implementing policies for the equitable inclusion of minoritised teachers in majoritarian education systems. These insights aim to promote deep diversity and representation. Key takeaways include: This systematic review identifies a research gap concerning the integration of teachers of colour and minority teachers. Addressing this gap involves understanding their unique needs and challenges within various political, social and educational contexts. There is a need for further comparative research on this topic to enhance knowledge and contribute to developing varied models for preparing, recruiting and retaining teachers of colour, thereby improving diversity in schools and supporting the success of minority students. Future policy design and implementation at both the district and school levels should focus on the training, recruitment, mentoring and retention of minority teachers. This includes identifying positive ecological dynamics at both district and school levels that support the integration of minority teachers and teachers of colour. In today‘s era of digital literacy and artificial intelligence (AI), we recommend researching the applicability, usage and impact of AI programs in enhancing equitable hiring processes. This research should explore how AI can be used to detect early warning signs of exclusion or marginalisation that may contribute to turnover among minority teachers, and how it can facilitate supportive interventions.

The last days of Aporia crataegi (L.) in Britain: Evaluating genomic erosion in an extirpated butterfly.

Current rates of habitat degradation and climate change are causing unprecedented declines in global biodiversity. Studies on vertebrates highlight how conservation genomics can be effective in identifying and managing threatened populations, but it is unclear how vertebrate-derived metrics of genomic erosion translate to invertebrates, with their markedly different population sizes and life histories. The Black-veined White butterfly (Aporia crataegi) was extirpated from Britain in the 1920s. Here, we sequenced historical DNA from 17 specimens collected between 1854 and 1924 to reconstruct demography and compare levels of genomic erosion between extirpated British and extant European mainland populations. We contrast these results using modern samples of the Common Blue butterfly (Polyommatus icarus); a species with relatively stable demographic trends in Great Britain. We provide evidence for bottlenecks in both these species around the period of post-glacial colonization of the British Isles. Our results reveal different demographic histories and Ne for both species, consistent with their fates in Britain, likely driven by differences in life history, ecology and genome size. Despite a difference, by an order of magnitude, in historical effective population sizes (Ne), reduction in genome-wide heterozygosity in A. crataegi was comparable to that in P. icarus. Symptomatic of A. crataegi's disappearance were marked increases in runs-of-homozygosity (RoH), potentially indicative of recent inbreeding, and accumulation of putatively mildly and weakly deleterious variants. Our results provide a rare glimpse of genomic erosion in a regionally extinct insect and support the potential use of genomic erosion metrics in identifying invertebrate populations or species in decline.

Dismantling Colonial Laughter: Tracing Emergent African Diaspora Stand-Up Comedy in French and German

This study redirects attention from English-speaking African diaspora stand-up productions to French and German language expressions of purposively selected comedians with recent immigration history from Africa performing within mainland Europe. Through a socio-historical interrogation of specific colonial histories and joke themes, the paper comparatively explores the French language stage acts of Fary Lopez, Samia Orosemane (France) and Cécile Djunga (Belgium and France) and the German language works of Dave Davis (Germany), Charles Nguela (Switzerland), and Soso Mugiraneza (Austria). The aim is to show how the individuated colonial histories of the nations in which these comics reside and the chronicles of their relations with Africa(ns) and Black peoples feature in joke formulations and satiric jibes of the jokesters. Through these explorations, this essay studies how stand-up comedy’s transformative power challenges societal norms and attitudes using the backdrop of the concurrently heterogeneous and dissimilar colonial histories of the African continent and its diasporas. Moreover, through its focus on non-English expressions, it presents the unique intersections of language, “race,” ethnicity and colonial histories, as well as the geographic and linguistic spread of the African diaspora beyond European nations with direct colonial contact with the continent. Thus, the enquiry posits joke performances as platforms for cultural expression and critique as well as a site within which African peoples negotiate their presence in non-African environments.

A social identity perspective on lesbian, gay, bisexual and transgender (LGBT) entrepreneurs’ networking behavior

PurposeThis study aims to draw upon entrepreneurial network resource and social identity theories to advance the understanding of LGBT entrepreneurial behavior. The authors focus on what resources are acquired by LGBT entrepreneurs from LGBT-specific networks, such as entrepreneurs’ associations or chambers of commerce, and why they might engage with them.Design/methodology/approachAs an initial scoping exercise, Study 1 quantitatively examined the different resources acquired via a survey of 109 LGBT entrepreneurs from the UK, mainland Europe and North America. Building on these findings, Study 2 qualitatively explored why LGBT entrepreneurs acquire resources from and engage with LGBT-specific networks via interviews with 23 LGBT entrepreneurs (with representation from the UK, Mainland Europe and North America).FindingsStudy 1 indicates that being more involved in LGBT-specific networks is associated with stronger resource acquisition, particularly those that are relational and psychological in nature. Study 2 reveals that such networks can act as psychologically safe holding environments where resources that fulfil needs for belonging and uniqueness are acquired. However, certain challenges and issues arise when trying to meet all members' needs.Practical implicationsThe findings underscore the need for LGBT networks that are run for, and by, LGBT entrepreneurs. Such networks allow LGBT entrepreneurs to be more authentic about, and empowered by, their LGBT identity in their business such that they can develop a stronger sense of individual and collective pride in being part of an LGBT entrepreneurial community. Yet, there is a need to understand the variety of identities and needs across the LGBT community.Originality/valueThe authors advance our understanding of LGBT entrepreneurs by connecting knowledge on entrepreneurship with that on applied psychology. The authors develop an original contribution by focusing on how LGBT entrepreneurs use LGBT-specific networks to meet important psychological and relational needs, thus speaking to the importance of developing an LGBT entrepreneurial community that enables LGBT entrepreneurs to express their LGBT and entrepreneurial identities.

Investigating the emergence of a zoonotic virus: phylogenetic analysis of European bat lyssavirus 1 in the UK.

European bat lyssavirus 1 (EBLV-1, Lyssavirus hamburg) is predominantly detected in serotine bats (Eptesicus serotinus) and is responsible for the majority of bat rabies cases in mainland Europe. A passive bat rabies surveillance scheme detected the virus in a serotine bat in the UK for the first time in October 2018. As of May 2024, 34 cases have been reported, 20 of which involved contact with an animal and 5 reported human contact. We investigated the emergence of EBLV-1 by undertaking comprehensive sequence analysis and Bayesian phylogenetics, based on complete virus genomes of 33 UK sequences and 108 sequences covering six countries in mainland Europe (1968-2023), including 21 French EBLV-1-positive RNA samples sequenced for this study. Sequence analysis revealed extreme similarity among UK EBLV-1 sequences (99.9%-100%), implying a single source of introduction rather than multiple independent introductions. Bayesian analysis revealed that the UK EBLV-1 sequences shared their most recent common ancestor with an EBLV-1 sequence from a serotine bat detected in Brittany, France, in 2001, with an estimated date of divergence of 1997. Within the UK sequences, the earliest divergence was estimated to occur in 2007. This study provides valuable insights into the molecular epidemiology of an emerging zoonotic pathogen and improved understanding of the risks posed to public and animal health.

Looking at the modern landscape of submediterranean Greece through a palaeoecological lens

The importance of understanding the long-lasting legacy of past land use on modern ecosystems has long been acknowledged. However, the magnitude and persistence of such legacies have been assessed only occasionally. Northern Greece has been a gateway of farming into mainland Europe during the Neolithic, thus providing a perfect setting to assess the potential impact of land-use history on present-day ecosystems. Additionally, the marked Holocene climatic variability of the southern Balkans makes it possible to investigate climate-vegetation-land use interactions over long timescales. Here, we have studied a sediment record from Limni Vegoritis (Northern Greece) spanning the past ∼9000 years using palaeoecological proxies (pollen, spores, stomata, microscopic charcoal). We aimed to reconstruct long-term vegetation dynamics in submediterranean Greece, to assess the environmental factors controlling them and to establish the legacies of the long history of land use in the modern landscape. We found that the Early Holocene afforestation, mainly oak woodlands, was delayed because of suboptimal moisture conditions. Later, colder and drier conditions during the rapid climate change centred around the ‘8.2 ka event’ triggered woodland opening and the spread of wooded (Juniperus) steppe vegetation. First indicators of farming activities are recorded during this period, but their abundances are too low to explain the concurrent large deforestation episode. Later, pinewoods (probably dominated by Pinus nigra) with deciduous Quercus spread and dominated the landscape for several millennia. These forests experienced repeated multi-centennial setback-recovery episodes associated with land-use intensification, but pines eventually declined ∼2500–2000 years ago during Classical times under heavy land use comprising intense pastoralism. This was the starting point for the present-day landscape, where the main ‘foundation’ taxon of the ancient forests (Pinus cf. nigra) is missing, therefore attesting to the strong imprint that historical land use has left on the modern landscape.

Quantitative risk assessment for the introduction of bluetongue virus into mainland Europe by long-distance wind dispersal of Culicoides spp.: A case study from Sardinia.

Europe faces regular introductions and reintroductions of bluetongue virus (BTV) serotypes, most recently exemplified by the incursion of serotype 3 in the Netherlands. Although the long-distance wind dispersal of the disease vector, Culicoides spp., is recognized as a virus introduction pathway, it remains understudied in risk assessments. A Quantitative Risk Assessment framework was developed to estimate the risk of BTV-3 incursion into mainland Europe from Sardinia, where the virus has been present since 2018. We used an atmospheric transport model (HYbrid Single-Particle Lagrangian Integrated Trajectory) to infer the probability of airborne dispersion of the insect vector. Epidemiological disease parameters quantified the virus prevalence in vector population in Sardinia and its potential first transmission after introduction in a new area. When assuming a 24h maximal flight duration, the risk of BTV introduction from Sardinia is limited to the Mediterranean Basin, mainly affecting the southwestern area of the Italian Peninsula, Sicily, Malta, and Corsica. The risk extends to the northern and central parts of Italy, Balearic archipelago, and mainland France and Spain, mostly when maximal flight duration is longer than 24h. Additional knowledge on vector flight conditions and Obsoletus complex-specific parameters could improve the robustness of the model. Providing both spatial and temporal insights into BTV introduction risks, our framework is a key tool to guide global surveillance and preparedness against epizootics.

On the occurrence of the Dragon leech Hirudo troctina Johnson, 1816 (Annelida, Hirudinea) in Sardinia (Italy)

In recent decades, medicinal leeches of the genus Hirudo have experienced a sharp decline throughout their distribution range due to their overexploitation for medical use and habitat alteration. Such a phenomenon is not fully understood because of the complex taxonomy of the genus, which remained unsettled until the beginning of the XXI century, when the implementation of DNA taxonomy allowed for a better understanding of the diversity of the genus and the distribution ranges of Hirudo species. Only the Mediterranean medicinal leech Hirudo verbana Carena, 1820 is currently reported to occur in Italy and its major islands, although records of other Hirudo species have been reported in the literature. In this study, we report the occurrence of the Dragon leech Hirudo troctina Johnson, 1816 in Sardinia and provide its molecular characterization. In addition, based on a review of the existing literature and museum collections, we provide an ample synopsis of the available evidence regarding the occurrence of the species on the island. Hirudo troctina proved to be widespread and abundant in Sardinia during the XIX century but became rarer and rarer in the XX and XXI centuries possibly due to its overexploitation for medicinal use and export in mainland Europe, the abandonment of traditional grazing practices, and the decline of wetland habitats and amphibian populations. Currently, the only recently validated occurrence sites of the species are the water bodies of the “Giara di Gesturi”, a basaltic plateau in central-southern Sardinia. No corroborated evidence of the possible occurrence of other Hirudo species on the island was found. A better understanding of Hirudo troctina distribution in Sardinia will allow the amelioration of its protection and management practices, also under the provisions of the European “Habitats Directive”, where the H. medicinalis species complex is listed in Annex V.

Ideological Hatred and the New Social Cleavages

The war in Ukraine pushed a large part of the planet to reformulate its narratives, its arguments and rationalities to accommodate an impossible reality: a real, hot war in the European mainland where everybody had already embraced the mantra of a for-ever post-war-scenario. With the politicians re-using old and highly symbolical expressions, all of us were driven in the middle of a semantic turmoil. One year after, we may easily distinguish the opposite camps all around the world and the line between them drawn by the new, post-communist source of dissonances: the bare ideology covered in fluid, transparent inter-textual coats, as if the war itself were just a synthesis of history, geopolitics, religion, modernization and international relations altogether. However, beyond all these, there comes a well-known theory to seek its own updates: Julien Benda labeled three types of hatred, namely of race, class and nation. My claim is that this war in Ukraine added a full-fledged new category of ideological hatred, cutting across the above mentioned ones as if annulling their existence and subordinating all to the present commands of politics. I intend to explore these divisions, tracing a line to connect all four types while searching for the anatomy of the new (old) ghost: the ideological hatred, how it works with the sociological categories of race, class and nation encapsulating them to create new political subjects. The latter are the combating parts in this war and we may say that the war renovated the sociological division of roles through reconfiguring the players in the game.

EWOM Information Richness and Online User Review Behavior: Evidence from TripAdvisor

The growing number of online users commenting on review platforms has fueled the development of electronic word–of–mouth (eWOM). At the same time, merchants have improved their requirements for the length and frequency of online reviews. However, few studies have examined the updating mechanism of online reviews length and frequency from the perspective of businesses. This study explores the relationship between online commenting platform users and eWOM and examines how eWOM information richness affects online user review behavior. We used media richness theory (MRT) to quantify the information richness of eWOM content (linguistic, textual, and photographical) to build an empirical framework. For the research data, we used advanced big data analytics to retrieve and analyze TripAdvisor data on restaurant services in nine major tourist destinations, the United States, Mexico, and mainland Europe (including UK, Spain, Netherlands, etc.), over a long period of time. Based on >10 million eWOM, this study used multiple regression to examine the impact of eWOM information richness on online user review behavior, considering the moderating effect of information ambiguity. Our research results show that content information richness positively affects online user review behavior, increasing their frequency and length. Information ambiguity play a moderating role that strengthens this relationship. This supports our theoretical hypothesis. Finally, for greater applicability and reliability, we conducted a comparative study on the degree of differences in the relationship between eWOM and users based on different cultural backgrounds across countries.

Identity and standards for English as a European Union lingua franca

AbstractThis article addresses, from an applied linguistics perspective, the position English maintains among the myriad of languages spoken in the European Union (EU). The linguistic make‐up of EU society, as well as the language policy of the Union, is scrutinised. The role English is playing in European unification is also important for the discussion, as is the call for a re‐evaluation of the norms deployed in English language teaching. The linguistic nativisation currently taking place in mainland Europe, which indicates that English is functioning more as an Outer Circle rather than as an Expanding Circle language, is juxtaposed with these developments.

Middle Pleistocene Hippopotamus amphibius (Mammalia, Hippopotamidae) from southern Europe: Implications for morphology, morphometry and biogeography

Hippopotamuses were present in Western Europe during the Pleistocene with at least two continental species: Hippopotamus antiquus and H. amphibius. The former was the large European hippopotamus, which appeared in the fossil record around 2 Ma and successfully spread across Europe before its last appearance datum (LAD) in Portugal and Greece, dated to 0.4 Ma. The extant hippopotamus, H. amphibius, first occurred in Africa around 1.5 Ma, and was well-established in Europe during the Late Pleistocene; however, its first occurrence datum (FOD) in Europe is still highly debated. Most of the H. amphibius remains collected from Middle Pleistocene localities are either badly preserved and fragmented or lacking clear stratigraphical data, in turn leading to doubtful specific attributions. A well-preservedmandible herein described, collected from Fosso Malafede (Latium, central Italy), allows to re-assess the occurrence of H. amphibius and to critically revise its earliest records. The morphological and morphometric characters of the studied remain, such as the general robustness of the studied mandible, the convex ventral profile of the mandibular corpus, the length of the teeth series, and the shape of the sagittal cross section of the mandibular symphysis, allow us to ascribe it to Hippopotamus amphibius. Fosso Malafede has been chronologically assigned to MIS 7 (∼0.25 Ma) and represents one of the best preserved H. amphibius specimen of the Middle Pleistocene of the European mainland. Accordingly, we discuss biochronological and paleobiogeographic implications, suggesting a critical revision of several remains from the Middle Pleistocene of southern Europe.

Three leafhoppers newly recorded from the European mainland (Hemiptera: Auchenorrhyncha: Cicadellidae), with notes on their habitats

The leafhopper fauna of the Iberian Peninsula is the least studied in Europe. Recent surveys in agroecosystem areas of southern Spain, specifically in Andalusia, aimed to identify potential Auchenorrhyncha vectors of the bacterium Xylella fastidiosa. During these surveys, three previously unrecorded species of Cicadellidae belonging to the subfamily Deltocephalinae have been discovered. These newly recorded species are Balclutha incisa (Matsumura), Cicadulina (Cicadulina) bipunctata (Melichar), and Maiestas angustisecta (Linnavuori). Generally, these species were previously only known from American, African and eastern Palaearctic regions. This work is the first to record these species on the European mainland. Detailed descriptions of adult specimens have been provided, along with information on their current distribution and host plants. The potential role of these leafhoppers as potential vectors of plant pathogens is discussed, highlighting their importance in agroecosystems.
