AbstractAimThe geographical distribution of bacteria is an important, but poorly understood, topic in microbial ecology. A major question is how broadly distributed generalist taxa, and limitedly distributed specialist taxa, vary across a latitudinal gradient in freshwater ecosystems. We predict that: (a) generalists and specialists exhibit latitudinal diversity gradient with different patterns; (b) their community assemblies are mainly driven by stochastic processes; and (c) generalists coexist through niche differences, while specialists coexist through fitness differences.LocationSixty lakes and reservoirs in China, ranging from 18° N to 50° N.Time PeriodJuly–August in 2012 and 2018.Taxa StudiedBacterioplankton.MethodsWe clustered zero‐radius operational taxonomic unit (zOTU) (subspecies‐like level) into operational taxonomic unit (OTU) (species‐like level) and calculated the intra‐specific variation and spatial asynchrony of OTU. We examined the relative effects of environment versus space (latitude) on bacterial community and quantified the community assembly processes of generalists and specialists, respectively. The binary‐state speciation and extinction (BiSSE) model has been used to estimate the evolutionary characteristics. The abundances of the top zOTUs within each OTU were identified to reveal their niche preferences (distribution patterns at different sites).ResultsWe found that bacterial generalists had a higher intra‐specific variation, greater asynchrony and wider niche width than the specialists. With increasing latitude, bacterial diversity decreased with abundance variations in generalists and occurrence variations in specialists, respectively. Diversification in stochastic processes was the main driving factor in both groups, though deterministic processes showed greater effects on specialists than generalists in local communities. Bacterial generalists coexisted through niche differences, whereas specialists coexisted through average fitness differences.Main ConclusionsWe demonstrated distinct latitudinal distribution patterns of bacterial generalists and specialists. These results highlight differences in biogeography of microbial generalist and specialist taxa mediated by intra‐specific variation and emphasize their distinctly vital roles mediated by differing mechanisms in freshwater ecosystems.

AbstractAimDespite the strong evidence of species range shifts as a response to environmental change, attempts to identify species traits that modulate those shifts have been equivocal. We investigate the role of species traits and environmental preferences on birds' range shifts in Great Britain, an island where dispersal is limited by the English Channel and the North Sea.LocationGreat Britain (England, Scotland and Wales).TaxaBirds (Aves).Time Period1968–2011.MethodsUsing 404,949 occurrence records from two time periods, we investigated the potential drivers of leading and rear range edge shifts of breeding birds using phylogenetic linear mixed models. We hypothesized that shifts are influenced by species' trophic and morphological traits, dispersal abilities and environmental preferences, but also by the geographical boundaries of Great Britain.ResultsGeographical boundaries—the distance from the northern or southern boundaries of Britain—accounted for most of the variability in range edge shifts. Species traits and environmental preferences emerged as relevant drivers of range shifts only for northern and Passeriform species. Northern habitat specialist, those with more predators and those sensitive to precipitation were more likely to shift their rear edge poleward. For Passeriformes, habitat generalists, species with smaller dispersal capabilities, under higher predatory pressure or associated with forest and grassland were more likely to shift their rear edge poleward.Main ConclusionsWhile geographical boundaries impose constraints on range shifts in British birds, the subtle effects of species traits and environmental preferences emerge as relevant predictors for Northern and passeriform species' rear edge shifts. This highlights the importance of accounting for geographical boundaries when predicting species responses to global change. Differential range shifts of species across different trophic levels could result in the reorganization of biotic interactions, with consequences for ecosystem structure and stability.
Anticipating resistance: Teaching gender and management to business school students
Authors: Stierncreutz Micaela , Tienari Janne 
Published: September 2023

AbstractGender perspectives and feminism are rarely considered legitimate in business school education. Existing research tells us that those who teach in business schools do so in conditions where feminist theories and pedagogy evoke resistance and where their work is paved with discomfort caused by tensions between feminist and neoliberal idea(l)s. We argue that for those challenging the status quo in the business school through teaching, the impact of the threat of resistance can be as “real” as that of realized resistance. In this paper, we engage with collaborative autoethnography and elucidate how our anticipation of resistance shapes the way we teach, even when resistance does not materialize in the classroom. Building on reflections of our shared experiences, we theorize anticipated resistance as productive in and of itself, challenging the conventional view of resistance as brought into being through resisting practices at a specific time and place.

AbstractBackgroundChildren and adolescents may experience pain in the lower limbs, predominantly at the end of the day or during the night, without any relation to organic disease. These pains are often called “growing pains” (GP) by pediatricians and orthopedists. They are commonly attributed to rapid growth.ObjectiveThe aim of this study was to review and characterize GP in children and adolescents as a precursor/comorbidity with migraine.MethodsThe study was of a cross‐sectional, prospective, longitudinal cohort, with group comparison. A sample of 100 children/adolescents born to mothers with migraine seen at a headache clinic was recruited in a random order chosen by lot, maintaining the ratio of 1:1 for the group with GP and the controls. Both groups were followed for a period of 5 years.ResultsAfter 5 years of follow‐up, 78 patients completed the study, of which 42 were from the GP group and 36 were from the control group. Headache fulfilling the International Classification of Headache Disorders, 3rd edition diagnostic criteria for migraine without aura or probable migraine occurred in 32/42 (76%) of patients with GP and in 8/36 (22%) of controls (p < 0.001). In the sample that initially had “growing pains,” these pains persisted in 6/42 (14%) and appeared in 14/36 (39%) of those who were previously asymptomatic (p = 0.026).ConclusionsPain in the lower limbs of children and adolescents, commonly referred to as GP by pediatricians and orthopedists, may reflect a precursor or comorbidity with migraine.

AbstractMucosal antibodies play a key role in protection against breakthrough COVID‐19 infections and emerging viral variants. Intramuscular adenovirus‐based vaccination (Vaxzevria) only weakly induces nasal IgG and IgA responses, unless vaccinees have been previously infected. However, little is known about how Vaxzevria vaccination impacts the ability of mucosal antibodies to induce Fc responses, particularly against SARS‐CoV‐2 variants of concern (VoCs). Here, we profiled paired mucosal (saliva, tears) and plasma antibodies from COVID‐19 vaccinated only vaccinees (uninfected, vaccinated) and COVID‐19 recovered vaccinees (COVID‐19 recovered, vaccinated) who both received Vaxzevria vaccines. SARS‐CoV‐2 ancestral‐specific IgG antibodies capable of engaging FcγR3a were significantly higher in the mucosal samples of COVID‐19 recovered Vaxzevria vaccinees in comparison with vaccinated only vaccinees. However, when IgG and FcγR3a engaging antibodies were tested against a panel of SARS‐CoV‐2 VoCs, the responses were ancestral‐centric with weaker recognition of Omicron strains observed. In contrast, salivary IgA, but not plasma IgA, from Vaxzevria vaccinees displayed broad cross‐reactivity across all SARS‐CoV‐2 VoCs tested. Our data highlight that while intramuscular Vaxzevria vaccination can enhance mucosal antibodies responses in COVID‐19 recovered vaccinees, restrictions by ancestral‐centric bias may have implications for COVID‐19 protection. However, highly cross‐reactive mucosal IgA could be key in addressing these gaps in mucosal immunity and may be an important focus of future SARS‐CoV‐2 vaccine development.

AbstractAimThis study aims to (1) describe trends in explanations provided for racial/ethnic inequities in dental caries and periodontitis, and (2) explore the patterns of relatedness among explanations for these inequities.Materials and MethodsHighly cited publications based on studies indexed in the Scopus database were retrieved and assessed for eligibility. Explanations for racial/ethnic inequities were classified into eight different, but interrelated domains. We assessed trends and examined the relations among explanations using multiple correspondence analysis.ResultsA total of 200 articles among the most cited publications were selected. The proportion of studies invoking racism as an explanation for racial inequities in oral health increased from 0% to 14.3%, from 1937 to 2020. The proportions of individual socio‐economic factors increased from 52.0% to 82.9%, and dental care from 28.0% to 62.9%. The remaining explanations were stable: psychological/behavioural processes (62.5%), biological factors (49.5%), contextual/area‐level effects (24.0%) and immigrant paradox (4.0%). Multiple correspondence analysis revealed a smaller axial distance between racism and the following categories: studies from Brazil, recent publications and Blacks/Hispanics/mixed‐race groups. Publications about immigrants were axially closer to the high‐income countries category.ConclusionsOur findings call on dental researchers to consider racism as a cause for existing racial/ethnic inequities in oral health.
Broad‐spectrum sunscreens containing the TriAsorB™ filter: In vitro photoprotection and clinical evaluation of blue light‐induced skin pigmentation

Published: September 2023

AbstractBackgroundBlue light (BL), particularly high‐energy visible (HEV) light (400–450 nm), can cause skin damage and pigmentation. Therefore, effective sunscreens should offer photoprotection beyond ultraviolet (UV) radiation to also prevent or limit BL‐induced cutaneous effects.ObjectivesTo evaluate the in vitro BL photostability and photoprotection properties of nine sunscreens containing the broad‐spectrum UV/BL phenylene bis‐diphenyltriazine (PBDT or TriAsorB™) filter, together with three other organic UV filters, and to assess the in vivo photoprotection level provided by two of these products against BL‐induced skin pigmentation.MethodsIn vitro BL photostability and photoprotection factors, comprising the percentage of BL radiation stopped by the product (%BL) and the critical wavelength extended to BL (BL‐CW), were determined by spectrophotometry. The in vivo photoprotection provided by two representative sunscreens (i.e. similar formulations, one non‐tinted and one tinted) was assessed in two open randomized studies (20 and 16 women, respectively) after exposure of two test areas (with and without sunscreen) on the back of each subject to a 412‐nm irradiation dose at 50 J/cm2, using instrumental and clinical measurements of skin pigmentation. The percentage sunscreen photoprotective effectiveness (%PPE) was calculated by comparing intrasubject post‐exposure pigmentation changes between the with and without sunscreen test areas.ResultsIn vitro, the nine PBDT‐containing products were highly photostable and had a BL‐CW ≥385 nm and a %BL ≥30% (range: 30%–50%), thus allowing effective BL photoprotection. In vivo, both representative sunscreens prevented BL‐induced immediate skin pigmentation (1 and 24 h post‐exposure) with %PPE values ranging from 50.7% to 75.5% for colorimetric assessments (p < 0.001) and from 31.2% to 72.7% for visual scores (p ≤ 0.001).ConclusionsAll PBDT‐containing sunscreens were considered effective at absorbing BL radiation in vitro. The two representative broad‐spectrum sunscreens tested in subjects significantly reduced BL‐induced immediate skin pigmentation following single exposure to monochromatic BL radiation.

AbstractThe pyjama shark (Poroderma africanum) is a Scyliorhinid species endemic to South Africa. Even though it is kept in captivity in many aquaria, there is a lack of research on its growth and development. In this study, we investigated the fertilization rate of eggs and the age at female sexual maturation in captive sharks and compared their growth to that of wild individuals. This is the first study to compare the growth of captive and wild catsharks as well as the first study to compare growth in male and female pyjama sharks and benefits from a much larger sample size than has previously been collected. The mean incubation rate (±standard error of the mean [SE]) was 239.46 ± 4.97 days, the mean Lt of hatchlings (±SE) was 14.65 ± 0.24 cm, and the mean Wt (±SE) was 17.19 ± 0.75 g. The observed ratio of male to female offspring (1:3.5) was also significantly different from 1:1. One female laid fertilized eggs 6.6 years after hatching and was considered sexually mature. Both in captivity and in the wild, males showed negative allometric growth and females showed isometric growth. The growth performance (Φ') was also greater in captive sharks compared to wild sharks regardless of sex. However, there was significant variation in growth between individuals of the same sex. The similar growth patterns (i.e., allometry and isometry) found in wild and captive populations are a very useful tool for informing future conservation management if the population of this shark species were to decline in the future and also prove that captive studies for this species are transferable to wild populations with regard to sexual differences. This study also provides a benchmark for further captive studies in other lesser‐studied catshark species and raises interesting questions concerning sexual differences in growth for other shark species.

Published: September 2023

AbstractIn mid‐May 2022, pink salmon Oncorhynchus gorbuscha smolts were caught in the rivers Botnsá, Grímsá, and Langá in Iceland. This observation provides the first evidence of successful spawning and the completion of the freshwater phase of the life cycle in Icelandic rivers. It is the most western record of O. gorbuscha smolts in Europe, further west than Russia, Norway, and the UK. Smolts originating from Iceland potentially support the recruitment of this species in the North Atlantic and may lead to the establishment of a self‐sustaining population in Iceland.

AbstractUsing a panel smooth transition regression framework on a new proxy of the business cycle (BC) index and quarterly data of US bank holding companies from 1993Q1 to 2020Q1, our results provide empirical support for the theory that the BC has a nonlinear effect on liquidity creation. We find a positive and highly significant nonlinear effect of the BC on liquidity creation, which not only supports the pro‐cyclicality of liquidity creation but also improves the liquidity creation estimation compared to previous studies. The results are robust to different proxies of the BC and model specifications. We also document that US bank holding companies create liquidity more during the expansion phase (normal times) than during the recession phase (crisis times) of the BC, suggesting an asymmetrical effect of BC changes on liquidity creation. Our findings have important implications for financial market participants by suggesting that banks should keep alternative sources of funding on hand during the BC recession phase. Insights from our study also provide policy implications for central banks and prudent supervisors to consider when incentivizing banks, for instance, by lowering regulatory requirements, adjusting the policy rate, or implementing any other quantitative easing policy during the BC recession phase to keep the financial system efficient.
Achieving collaborative innovation by controlling or leveraging network complexities through complexity leadership
Authors: Callens Chesney 
Published: September 2023

AbstractRecent innovation research in the public sector demonstrates the advantages of collaborative innovation, but also recognizes the complex character of collaborative innovation processes. These complexities might both stimulate and hinder collaborative innovation. Through a qualitative comparative analysis of empirical data from 19 public–private innovation partnerships (PPIs) in five European Countries, we show how particular types of complexity leadership (i.e., generative leadership and administrative leadership) act on these complexities in PPIs to produce highly innovative services. The results show that small partnerships use generative leadership in the presence of network complexities, and administrative leadership in the absence of network complexities to produce highly innovative services. However, large partnerships only use generative leadership, while abandoning administrative leadership, to produce highly innovative services. These findings bring about theoretical and practical insights as to how various forms of complexity leadership might be employed in varying contexts of partnership complexity.
Kant's Racism as a Philosophical Problem
Authors: Ramsauer Laurenz 
Published: September 2023

AbstractImmanuel Kant was possibly both the most influential racist and the most influential moral philosopher of modern, Western thought. So far, authors have either interpreted Kant as an “inconsistent egalitarian” or as a “consistent inegalitarian.” On the former view, Kant failed to draw the necessary conclusions about persons from his own moral philosophy; on the latter view, Kant did not consider non‐White people as persons at all. However, both standard interpretations face significant textual difficulties; instead, I argue that Kant's moral egalitarianism is so thin as to remain almost entirely useless as an antidote to racism.
Graded and ungraded expectation patterns: Prediction dynamics during active comprehension
Authors: Lai Melinh K. , Payne Brennan R. , Federmeier Kara D. 
Published: September 2023

AbstractLanguage comprehension can be facilitated by the accurate prediction of upcoming words, but prediction effects are not ubiquitous, and comprehenders likely use predictive processing to varying degrees depending on task demands. To ascertain the processing consequences of prioritizing prediction, we here compared ERPs elicited when young adult participants simply read for comprehension with those collected in a subsequent block that required active prediction. We were particularly interested in frontally‐distributed post‐N400 effects for expected and unexpected words in strongly constraining contexts, which have previously been documented as two distinct patterns: an enhanced positivity (“anterior positivity”) observed for prediction violations compared to words that are merely unpredictable (because they occur in weakly constraining sentences) and a distinction between expected endings in more constraining contexts and those same weakly constrained words (“frontal negativity” to the strongly predicted words). We found that the size of the anterior positivity effect was unchanged between passive comprehension and active prediction, suggesting that some processes related to prediction may engage state‐like networks. On the other hand, the frontal negativity showed graded patterns from the interaction of task and sentence type. These differing patterns support the hypothesis that there are two separate effects with frontal scalp distributions that occur after the N400 and further suggest that the impact of violating predictions (as long as prediction is engaged at all) is largely stable across varying levels of effort/attention directed toward prediction, whereas other comprehension processes can be modulated by task demands.
Negotiating civic identity across different political contexts: Immigrant participation in social movements and political incorporation
Authors: Chow Cheng , Ren Lifeiyang 
Published: September 2023

AbstractThis article examines the understudied intersection between migration and contentious politics, focusing specifically on immigrant participation in social movements within their host societies. Drawing upon data from the Anti‐Extradition Law Amendment Bill (Anti‐ELAB) Movement in Hong Kong, it illuminates the process through which Chinese immigrants become politicized, evolve collective identities, and mobilize against civil dominance. Further, it underscores the transformative potential of social movements in facilitating immigrant political incorporation. However, it also recognizes the unilateral acceptance determined by mainstream society, which often leaves immigrants sidelined in discussions regarding their qualifications for unconventional political participation. To address civil inequality, immigrants establish their civil identities, challenge dominance, and amass political capital for future incorporation. This study extends the migration and social movements literature by shedding light on the political dynamics of immigrant participation and the hurdles they encounter during their journey toward political incorporation. It also underscores the significant role of progressive social movements in fostering immigrant political participation. Furthermore, the research highlights the unique immigrant political identity that emerges and evolves through participation in social movements, contesting exclusion and monopolistic dominance over democratic realization.
