Using data from the understudied language Gιsιɖa Anii, we provide a formal analysis of irrealis that builds on the framework of modality proposed in Giannakidou and Mari. In particular, we propose that Anii has an irrealis modal morpheme whose meaning is that the speaker does not believe that the proposition is true at a particular time. This gives irrealis, at least in Anii, a negatively biased meaning. Giannakidou and Mari propose that the subjunctive in European languages is a positively biased modal but find no evidence in their data for a corresponding negatively biased one. However, in expanding their approach to a completely unrelated language, we show that modal bias can also be negative, filling in the paradigmatic gap left open by Giannakidou and Mari’s work. We also illustrate the utility of analyzing irrealis (in relation to the concept of veridicality) as a morphosyntactic and semantic category with a status similar to tense and aspect. Our formal analysis accounts for the obligatory realization of irrealis in a wide range of semantic contexts in Anii, including future tense, negation, and wishes, and shows how irrealis can be composed with other clausal elements. We suggest that reality status, which we analyze as (non)-veridicality, is obligatorily present in the Anii clause and discuss the implications of this for other languages.
Many early modern Italian nobles were obsessed with duelling. Despite bans from secular authorities and the Council of Trent, the violent honor complex was veiled in part under the title of the scienza cavalleresca, the knightly science, which provided rules for the conduct of conflicts between aristocrats and those with noble aspirations. Such rules were both concerned with emotions and the object of emotions. Using the tools of the history and sociology of emotions, this article contributes to the emotional history of the scienza cavalleresca through examining the rules proposed both as feeling rules in themselves and as objects of emotional judgment. Toward the turn of the eighteenth century, more aristocrats began rejecting such codes with explicit objections to the scienza cavalleresca and its ethical basis. One such noble was Paolo Mattia Doria (1667–1746), a notorious duellist in the closing years of the Spanish regime, who renounced the vendetta and expressed disgust with its practitioners. A zealous convert against the noble vengeance system, he will serve as an example to explore the wider struggle over emotional values in early modern Italy and, more generally, in societies with high levels of violence. The article traces the role of emotions in the scienza cavalleresca, the taste for dispute through one genre (letters of challenge or cartelli di sfida), then explores the case of Doria. From these three stages, the article argues for the significance of adopting approaches from the sociology of emotions to analyze elite cultures of violence.
The confluence of extreme weather conditions and crowded forests are contributing to larger and more severe forest fires. The progressive migration of the US population into the wildland-urban-interface is placing more people in the path of wildfire, while the emissions from wildland fire are reversing historical improvements in national air quality and placing the health of people remote from the wildfire at risk. The presentation will describe the historical pattern of wildfire in the U.S., factors contributing to a significant increase recently, and projections for wildfire behavior into the future. The human health effects of wildfire will be addressed within the context of mental health issues emerging among survivors of wildfire, and health effects to exposure to emissions of firefighters, and populations at a distance. Clinical and public health recommendations for individuals and communities to protect themselves from smoke exposure will be presented.
Learning Objectives
Describe the factors that are increasing the size and severity of wildfire.
Describe actions individuals and communities can take to reduce exposure to wildfire smoke.
Describe key unanswered questions requiring new research to inform policy and decision-making by professionals charged with managing forests and environmental quality, prescribed fire, public health and healthcare.
This paper examines the population of corporate directors of Britain at the turn of the twentieth century. Over the period 1881-1911 the corporate form became the most common mode of business organisation for large businesses. As their number increased, the population of directors expanded and reflected an increasingly diversified corporate landscape. Based on a large-scale dataset, this paper analyses the characteristics and networks of this wider population of directors. The study goes beyond previous work, which has mainly focused on elite directors or prominent companies, and shows three key findings. First, the population of directors was very connected into a large network, complete isolation from this network was rare. Second, over 1881-1911 director interlocks with banks became less important for most sectors, while interlocks with other financial institutions such as trusts became increasingly important. Insurance companies stood out as the most connected sector spanning smaller local companies and larger international ones. Third, during the period studied there was a shift from director clusters that were mainly based on proximity, to those that were connected through industries.
The twentieth-century processes of legal modernization rendered transformations to the concept of authority and its public perception. This article builds on the complex Weberian articulations of these transformations to analyze a contemporary contentious debate concerning the establishment of a Rabbinical Court of Appeals, in Mandatory Palestine, between 1918 and 1921. This initiative, imposed by the British government and supported by non-religious Jewish leaders, raised a heated controversy between two rabbinical figures—Haim Hirschnson of Hoboken, New Jersey, and Ben-Zion Uziel of Jaffa. Based on a close reading of their texts, juxtaposing them to Weberian conceptualizations of modern authority, and contextualizing them in particular historical circumstances, I argue that both rabbis comprehended the appellate mechanism as transforming the concept of rabbinical authority. By instituting appellate courts, authority shifts from its “charismatic” or “traditional” form to a “legal” institutional-based form. They harshly disagreed, however, if this transformation is a positive development in the modernization of Jewish law, or, on the contrary, will have a detrimental impact on the public's trust in the judiciary. The rabbinical articulations of these Weberian themes, as I suggest to interpret their texts, shed light on the application of the Weberian theory of bureaucracy to the judicial system and legal profession and also provide illuminating insights into the analysis of current church-law relationships, in Israeli law and elsewhere.
In the present work, the tangential (swirl) velocity component is superimposed at the intake of a narrow fluidic cylindrical pipe to achieve the desired mixing of inelastic non-Newtonian fluids/solutes at the outlet. We discuss an analytical method for obtaining the swirl velocity profile, considering the nonlinear viscous effects for both shear-thinning and shear-thickening fluids, represented by the power-law model. We numerically solve the species transport equation, coupled with the analytically derived swirl velocity, using our in-house developed code for the concentration distribution in the flow field. The results show that the inlet swirl and an increase in the shear-thinning fluid property improve advection-dominated mixing. Additionally, higher Reynolds numbers significantly enhance advection's dominance, as more rotation leads to the generation of vortices, resulting in an engulfment flow (chaotic convection) based mixing. We demonstrate that considering the increase in the shear-thinning fluid property with swirl intake reduces the amount of mixing time required in the convective regime.
The complex behaviours of supersonic turbulent boundary-layer flows interacting with combustion is explored through the use of direct numerical simulations. The chosen flow model is a non-premixed hydrogen–air flame ignited within a three-dimensional supersonic turbulent flat-plate boundary layer operating at a Mach number of 2.33 and a friction Reynolds number of approximately 1000. The simulation involves a finite-rate model for the hydrogen–air reaction including 9 species and 19 steps with adiabatic non-catalytic wall conditions. The inlet flow consists of preheated air in the main stream and a hydrogen film injected in proximity to the cold wall, inducing mixing and ignition in the outer layer. The specific inlet configuration leads to two successive transition stages of distinct mechanisms, with the first stage related to the mixing-layer instability and the second one to the boundary-layer instability. The excess Reynolds stresses resulting from the transition exhibit a downstream decrease, with values being lower than canonical adiabatic profiles, particularly in the outer layer. This difference is attributed to the reduced local friction Reynolds numbers, associated with the non-classical wall-normal distributions of density and viscosity. The effect of combustion on the recovery process and skin friction is analysed in comparison with a supplemented chemistry-frozen setting. Velocity–temperature and velocity–species correlations are further examined. The wall-normal profiles of turbulent Prandtl number tend to classical non-reacting values and the turbulent Schmidt number is only slightly affected by the reaction. The strong Reynolds analogy linking velocity and temperature fluctuations is found to be invalid in the outer layer due to the presence of large-scale temperature fluctuations and the inhomogeneity of hydrogen gas distribution, as revealed by a spectrum analysis. A statistical analysis of elementary reactions at varying wall-normal distances is provided, highlighting the dominance of hydrogen atom depletion in the inner region and the prevalence of water vapour production in the outer region, together contributing to the chemical heat release across the boundary layer. Turbulence–chemistry interaction is assessed through a comparison of mean turbulent and laminar chemical heat release rates, showing significant differences of up to an order of magnitude. Using a simple diagnostic tool, the modelling of fluctuations associated with hydrogen gas and two intermediate products is found to be crucial for turbulent chemistry closure.
This study utilises panel data of 46 countries from 2005 to 2019 to examine the impact of digital service trade (DST) on inclusive growth. Inclusive growth is a growth model that promotes economic growth and development, while also building social equity and inclusiveness and balancing environmental sustainability. The findings indicate that a nation’s DST development significantly fosters domestic economic growth and development, specifically through its employment enhancement effect. DST substantially promotes social equity and inclusiveness, mainly through the inclusive innovation effect. However, DST is also found to increase carbon emissions, impeding environmentally sustainable growth, specifically via the energy demand effect. Hence, DST exerts diverse impacts on different facets of inclusiveness. The study also reveals heterogeneity in the effects of DST on the three aspects of inclusive growth related to trade’s import–export dynamics, income levels, and DST barrier intensities. This paper contributes to and refines the body of research on the relationship between DST and inclusive growth. It offers policy suggestions for crafting more open and mutually beneficial DST policies to foster social equity and inclusive global trade.
Modern warfare has challenged the way in which far-forward medical assistance is provided in such settings. Since the existing approach and tools are insufficient for the changing landscape and humanitarian assistance, steps need to be taken to support an appropriate response. Of particular importance is the revision of a curriculum that fits the civilian medical system and facilitates its adaptation to the context and available resources.
Learning Objectives
Present the correlation between the asymmetry in warfare, the implementation of an integrated trauma system and its application in the management of civilian casualties.
Understand how lessons from the implementation of trauma care close to the frontlines contribute to generate a model for the provision of trauma care in asymmetric conflict.
This paper analyses the ethnic penalty by focusing on the racialization of labor market outcomes beyond the migrant penalty. An illegitimate statistical or taste-based discrimination can be revealed specifically by distinguishing migrants into ethnic groups. Accordingly, ethnic penalty based on five different ethnic groups was estimated through the difference in employment and job quality with respect to natives. The analysis was conducted at the country and European average levels using 16 European countries under a framework of ethnic penalty processes in the labor market. According to the analysis, Eastern Europeans were the most prominent ethnicity regarding higher employment across the 16 countries, although they were mostly posited in unskilled jobs. Migrants from the Middle East and North Africa were shown to be subject to a double penalty in both measures, and the penalty tendency was much clearer for females. Asians and South Americans showed the least penalty, while sub-Saharan Africans were revealed to hold an in-between position.
Previous work suggests that African American and Latino voters lack political cohesiveness. Recently, these findings have been cited by opponents of “minority aggregation,” which is the idea that African Americans and Latinos can be thought of as constituting a single “class of citizens” when filing claims under the Voting Rights Act. I replicate one influential study, Rocha (2007), with updated data and greater attentiveness to moderating conditions that are meaningful in voting rights law. My findings suggest African Americans and Latinos are more cohesive than previously thought, especially in majority–minority jurisdictions. Furthermore, cohesion cannot be explained solely by shared partisanship.
In this study, the resolvent-based estimation (RBE) is further generalised to cases with arbitrarily sampled measurements in time, where the generalised RBE is denoted as GRBE in this study. Different from the RBE that constructs the transfer function at each frequency, the GRBE minimises the estimation error energy in the physical temporal domain by considering the forcing and noise statistics. The GRBE is validated by estimating the complex Ginzburg–Landau equation and turbulent channel flows with the friction Reynolds number $Re_{\tau }=186$, 547 and 934, where the results from the RBE are also included. When the measurements are temporally resolved, the estimation results of the two approaches are equivalent to each other, and both match well with the reference numerical results. For the temporally unresolved cases, the estimation errors from the GRBE are obviously lower than those from the RBE. After validation, the GRBE is applied to investigate the impacts of the abundance of the measured information, including the temporal information and sensor types, on the estimation accuracy. Compared with the mean square error (MSE) in the estimation with temporally resolved measurements, that with measurements at only one snapshot, i.e. without any temporal information, increases by approximately $15\,\%$. On the other hand, it can effectively improve the estimation accuracy by increasing the number of sensor types. With temporally resolved measurements, the relative MSE decreases by $12.3\,\%$ when the sensor types increase from $\lbrace \tau _u \rbrace$ to $\lbrace \tau _u,\tau _w,p \rbrace$, where $\tau_u$, $\tau_w$ and p are the streamwise shear stress, spanwise shear stress and pressure at the wall. Finally, several existing forcing models are incorporated into the GRBE to investigate their performance in the linear estimation of flow state. The wall-distance-dependent model (W-model) results match well with the optimal linear estimations when the measurements are temporally unresolved. Meanwhile, with the increase of temporal information of the measurement, the estimation errors from the tested W-model and the scale-dependent model ($\lambda$-model) both increase, which contradicts the tendency observed in the optimal linear GRBE estimation results. Such a phenomenon highlights the importance of proper modelling of the forcing in the temporal domain for the accuracy of flow state estimation.
Flood is one of the major public health concerns increasing the risk of childhood diarrhea. This study aims to explore the association of floods with diarrhea among under-five children in rural India.
Methods
A cross-sectional study was carried out using large-scale nationally representative data from the National Family Health Survey-5. The Central Water Commission reports between the years 2018 and 2020 were used to group all the districts as non-flood-affected districts or flood-affected districts. Bivariate and multivariate logistic regression models were employed to assess the association of floods with childhood diarrhea.
Results
The prevalence of diarrhea was higher among children exposed to three consecutive floods during the year 2019-21 than those children not exposed to flood. Children exposed to flood three times between the year 2018-19 to 2020-21 were associated with a 34% higher likelihood of developing diarrhea than those children exposed to flood one or two times.
Conclusions
Our study suggests that community health workers should target mothers belonging to the poor wealth quintile, young mothers, and mothers with young infants and more children to receive child health related counseling in flood-prone areas.
The choice between primary repair and staged repair strategy for Tetralogy of Fallot remains a subject of debate in clinical practice. This review aims to compare the outcomes and efficacy of two surgical approaches in managing Tetralogy of Fallot among neonatal populations. Literature search was conducted across seven databases, identifying a total of 1393 relevant studies. Inclusion criteria encompassed comparative studies focusing on primary repair and staged repair for Tetralogy of Fallot in neonates. Quality of included studies was assessed using The Newcastle-Ottawa Scale for retrospective cohort studies. Data synthesis involved the extraction of post-operative outcomes. Meta-analysis was performed where feasible, pooling effect sizes to determine the overall impact of each repair strategy. Eight studies were selected for full-text appraisal. A total of 4464 Tetralogy of Fallot patients underwent surgical correction. The pooled mean patient age was 8.68 (±7.38) and 8.56 (±6.8) days for primary repair and staged repair, respectively. The primary repair was associated with a higher cardiac complications rate (odds ratio 1.50, 95% confidence interval 1.07 to 2.10) and transannular patch usage (odds ratio 2.62, 95% CI confidence interval 2.02 to 3.40). In contrast, staged repair was associated with longer hospital (mean difference 11.84, 95% confidence interval 9.59 to 14.10) and ICU (mean difference 3.06, 95% confidence interval 1.64 to 4.47) length of stay. However, no substantial differences were observed in terms of mortality and reintervention rates between these two approaches. The findings highlight the need for well-designed research and emphasise the importance of personalised approaches to address the intricate nature of Tetralogy of Fallot management in this population. Adjusting surgical approach to patient features may be necessary to maximise surgical outcomes.
Single-molecule techniques to analyze proteins and other biomolecules involving labels and tethers have allowed for new understanding of the underlying biophysics; however, the impact of perturbation from the labels and tethers has recently been shown to be significant in several cases. New approaches are emerging to measure single proteins through light scattering without the need for labels and ideally without tethers. Here, the approaches of interference scattering, plasmonic scattering, microcavity sensing, nanoaperture optical tweezing, and variants are described and compared. The application of these approaches to sizing, oligomerization, interactions, conformational dynamics, diffusion, and vibrational mode analysis is described. With early commercial successes, these approaches are poised to have an impact in the field of single-molecule biophysics.
In an open channel flow, deviations to the lower topography can induce abrupt changes in the wave height, known as hydraulic jumps. This phenomenon occurs when the flow switches from subcritical to supercritical (or vice versa), and is commonly observed in rivers, flumes and weirs. Theoretical insight is typically sought through the study of reduced models such as the forced Korteweg–de Vries equation, in which previous work has predominantly focused on either stationary formulations or the initial transient behaviour caused by perturbations. In a joint theoretical and numerical study of the free-surface Euler equations, Keeler & Blyth (J. Fluid Mech., vol. 993, 2024, A9) have detected a new class of unsteady solutions to this problem. These emerge from an unstable steady solution, and feature large-amplitude time-periodic ripples emitted from a sudden decrease in the water depth forced by topography, known as a hydraulic fall.
This article explores relations between transcultural processes and historical boundaries. Drawing on the Deleuzo-Guattarian concept of assemblage, it examines the selection and organisation of cultural elements in a Japanese-styled Chinese New Year installation at a Hong Kong shopping mall. The article presents three affective regimes produced in this transcultural assemblage: New Year festivity, simulated tourism, and partial historicity. We argue that these regimes are regulated in the processes of erasure (the selective blockage of competing lineages of rituals, traditions, and spaces) and forgetting (the process evoking creative re-organisation of semiotic boundaries between cultural elements selected into the transcultural assemblage). This article suggests two implications. First, transculturality is not only the dialogic transgression and creation of boundaries but also the selection and regulation of cultural elements in an assemblage. Second, historical boundaries are not sidestepped but are regulated by the partial blockage through erasure and re-organisation through forgetting in affective regimes. (Transculturality, assemblage, affective regime, erasure, forgetting, Hong Kong)
