We investigate the gender gap in issue attention among members of parliament (MPs) by applying automated text analytic techniques to a novel data set on Italian parliamentary speeches over a remarkably long period (1948–2020). We detect a gendered specialization across issues that tends to disappear as women’s shares in parliamentary groups increase. We then investigate whether women’s access to previously male-owned issues brings with it a different agenda, operationalized as a different vocabulary. We detect a U-shaped pattern: language gender specificity is high when female MPs are tokens in parliamentary groups with a large preponderance of men; it decreases when their shares start increasing and grows again when they constitute a considerable minority. We argue that this pattern is consistent with the theory of tokenism, and it is produced by the interlinkage of commitment to shared norms and the distribution of “activation thresholds” among female MPs.
In this paper, I argue for Fit, a prudential version of the claim that attitudes must fit their objects, the claim that there is an extra benefit when one's reactions fit their objects. I argue that Fit has surprising and powerful consequences for theories of well-being. Classic versions of the objective list theory, hedonism, desire views, and loving-the-good theories do not accommodate Fit. Suitable modifications change some of the views substantially. Modified views give reactions a robust role as sources of well-being, and they accept that objects call for some attitudes but not others. I argue that objective list theories and loving-the-good theories require the most minimal changes to accommodate Fit, so we have a pro tanto reason to favor these views over alternatives.
Solving a nonsmooth and nonconvex minimization problem can be approached as finding a zero of a set-valued operator. With this perspective, we propose a novel Majorizer–Minimizer technique to find a local minimizer of a nonsmooth and nonconvex function and establish its convergence. Our approach leverages Bregman distances to generalize the classical quadratic regularization. By doing so, we generate a family of regularized problems that encompasses quadratic regularization as a special case. To further demonstrate the effectiveness of our method, we apply it on a lasso regression model, showcasing its performance.
During a pioneering aerial survey of the Near East in the 1920s, Father Antoine Poidebard recorded hundreds of fortified military buildings that traced the eastern frontier of the Roman Empire. Based on their distribution, Poidebard proposed that these forts represented a line of defence against incursions from the east. Utilising declassified images from the CORONA and HEXAGON spy satellite programmes, the authors report on the identification of a further 396 forts widely distributed across the northern Fertile Crescent. The addition of these forts questions Poidebard's defensive frontier thesis and suggests instead that the structures played a role in facilitating the movement of people and goods across the Syrian steppe.
Sufficient vitamin D status is crucial for successful pregnancy and fetal development. The assessment of 25-hydroxyvitamin D (25(OH)D) concentrations is commonly used to evaluate vitamin D status. Our objective was to examine the interrelated biodynamics of maternal and neonatal total, free and bioavailable 25(OH)D in maternal–neonatal dyads at birth and their associations with homeostasis and neonatal birth anthropometry. We analysed a cohort of seventy full-term mother–child pairs. We found positive associations between all neonatal measures of vitamin D status. Maternal forms exhibited a similar pattern of association, except for the bioavailable maternal form. In multivariate analysis, both total and free maternal 25(OH)D concentrations were correlated with all neonatal forms (neonatal total 25(OH)D: 1·29 (95 % CI, 1·12, 1·46) for maternal total 25(OH)D, 10·89 (8·16, 13·63) for maternal free 25(OH)D), (neonatal free 25(OH)D: 0·15 for maternal total 25(OH)D, 1·28 (95 % CI, 0·89, 1·68) for maternal free 25(OH)D) and (0·13 (95 % CI, 0·10, 0·16), 1·06 (95 % CI, 0·68, 1·43) for maternal free 25(OH)D), respectively, with the exclusion of the bioavailable maternal form. We observed no significant interactions within or between groups regarding maternal and neonatal vitamin D parameters and maternal calcium and parathyroid hormone concentrations, and neonatal birth anthropometry. Our study indicates that bioavailable maternal and neonatal 25(OH)D have no significant effects on vitamin D equilibrium, Ca homeostasis and neonatal anthropometry at birth. However, we observed an interaction between maternal and neonatal total and free 25(OH)D concentrations at the maternal–neonatal interface, with no associations observed with other calciotropic or anthropometric outcomes.
Plant-based substitutes (PBS) are seen as a convenient way to transition to a more plant-based diet, but their potential health benefits and nutritional concerns remain debated. Based on a review of the literature, it is concluded here that the primary risk of insufficient nutrient intake with PBS concerns iron and calcium, which are critical to the nutritional value of PBS. Other risks were identified but these would depend on the characteristics of the overall diet, as is the case for iodine in a diet containing no seafood or dairy, and vitamin B12 in a vegetarian/vegan diet. Conversely, the use of PBS is also expected to confer some benefits for long-term health because it would result in higher fibre intakes (in the case of meat PBS) and lower SFA intakes (but higher PUFA/MUFA intakes), but attention should be paid to a potential increase in sodium intake with PBS of meat products. In fact, a recurring finding in this review was that PBS is a very heterogeneous food category involving considerable variations in ingredient and nutrient composition, and whose design could be improved in order to foster nutritional and health benefits. The latter also depend on the animal food that is being replaced and are only deemed likely when PBS replace red meat. The fortification of PBS with key nutrients such as iron and calcium may constitute an actionable public health solution to further shift the balance in favour of PBS in the context of the current dietary transition in western countries.
We study the coupled settling, deformation and mixing dynamics of a dense blob of fluid falling in an axially (vertically) linearly stratified Taylor–Couette cell (operated in a laminar stable regime). This configuration allows the independent analysis of stretching dynamics, driven by radial (horizontal) velocity variations, and settling dynamics, driven by buoyancy forces associated with vertical density variations. As the blob settles, it is stretched in the horizontal plane and forms an elongated lamella. Through the competing effects of transverse compression of the lamella due to this shear-induced stretching and broadening due to diffusion, the lamella irreversibly mixes with ambient fluid, thus progressively adjusting its own density towards that of the ambient fluid. Eventually, the lamella settling stops at a final equilibrium position that depends on the ambient vertical density gradient and the rate at which it has been deformed by the horizontal shear. We show how this final position is determined by stretching-enhanced diffusion, i.e. mixing. We demonstrate that a theoretical mixing model compares favourably with experiments with various Froude numbers (quantifying the relative strength of the horizontal shear and the vertical stratification) and construct a new criterion for the energetic ‘efficiency’ of this mixing process that explicitly captures its inherently diffusive character.
In this essay, I turn to the example of the 1919 Elaine Massacre—the deadliest incident of anti-Black violence in U.S. history—in order to better understand how its economically motivated, state-sanctioned, and brutally indiscriminate violence were nearly erased from history. I find that white journalists, military officials, as well as the Governor of Arkansas himself, drew upon long-standing race-based fears in their characterizations of what took place in Elaine. In so doing, they were able to simultaneously glorify and obfuscate the anti-Black violence, as well as further protect the property and economic interests of the white residents who had putatively been “under threat.” The scale of the violence in Elaine and the near totality of its erasure from the official record make the Elaine Massacre a chilling example of what Lindsay Schakenbach Regele has described as “martial capitalism”: the use of concealed military violence to wrest economic resources away from marginalized communities and toward their white counterparts.
This article investigates the pattern of economic voting at the regional level in Italy. It focuses on the elections held in 18 out of 20 Italian regions from 1995 to 2020. Retrospective voting is examined by using the theory of economic voting, measured at the subnational level. By providing some inferential models and controlling for the impact of phases of recession, this article tests the hypothesis whereby the incumbent regional government is rewarded (or punished) by voters in the event of a good (or poor) state of the regional economy. It mainly considers macroeconomic variables, focusing on the relationship between the unemployment rate (at both national and regional levels) and the electoral performance of the incumbent executive. The empirical analysis shows that, particularly during periods of ‘quiet politics’, economic voting also occurs at the local level and thus the regional unemployment rate affects regional rulers' electoral outcomes.
To advocate for restrictive immigration policies, conservative U.S. politicians have advanced a narrative that Latino immigrants commit violent crimes against White women. This framing of immigrant threat builds on a long history of similar anti-Black discourse and activates racialized ideas about protecting femininity. I demonstrate how the identities of purported victims of immigrant crime connect attitudes about immigration with benevolent sexism—a superficially positive, protective attitude toward particular types of women. An original survey experiment shows that benevolent sexism is activated when victims of immigrant crime are White women. Using nationally representative survey data, I show that the benevolent face of sexism has a notable impact on the immigration attitudes of White Americans, particularly when it comes to the protectionist policy of policing of the U.S.-Mexico border.
A coin always floats in stable equilibrium with its longitudinal axis normal to the air–liquid interface. In contrast, a long thin cylindrical pin floats with its longitudinal axis parallel to the air–liquid interface. In this context, we present a theoretical investigation of the stability of small-scale hydrophobic cylinders floating in vertical and horizontal orientations at various aspect ratios (length/diameter). The study is limited to cylinders denser than water floating at the air–water interface. Our analysis shows that, unlike large-scale vertically floating cylinders, the stability of vertically orientated small-scale cylinders increases with an increase in aspect ratio. A similar trend is observed in the stability of small-scale horizontal cylinders. We also explain the underlying mechanics that leads to a rise in the stability of floating cylinders with an increase in aspect ratio. Unlike large-scale floating cylinders with uniform density, we show that the effect of governing forces (weight, buoyancy and surface tension) in small-scale cylinders changes from a stabilising to a destabilising force with a change in the aspect ratio. For example, in the case of a vertically floating cylinder, the buoyancy force acts as a stabilising force at a small aspect ratio whereas, at large aspect ratios, the buoyancy force has a destabilising influence. Likewise, the body's weight has a destabilising influence at a small aspect ratio and stabilising effect at a large aspect ratio. The reason behind this transformation is that, above a particular aspect ratio, the centre of gravity of small-scale floating cylinders lies below the centre of buoyancy.
The global trend towards heightened protection for geographical indications (GIs) has been bolstered by the incorporation of anti-evocation provisions in various bilateral and regional trade agreements, primarily led by the European Union (EU). While these anti-evocation measures have raised GI protection to an unprecedented level, they also place limitations on the freedom of expression and competition for other market players. This article conducts a critical analysis of the necessity of those restrictions by evaluating the justifications for implementing anti-evocation protection. Specifically, the analysis centres on the formal justifications put forth by law enforcement authorities and their direct contribution to enforcement errors and inconsistencies. Furthermore, inherent limitations within these justifications are also identified. Clarifying the rationale for anti-evocation protection and establishing a clearly defined scope of protection, substantiated by sound justifications, could effectively mitigate errors and inconsistencies in law enforcement and minimize any undue impact on the public interest. Countries that have adopted or are considering adopting anti-evocation protection, following the EU's lead, should exercise caution to avoid similar pitfalls.
We study the effect of railroads, the single largest public investment in colonial India, on human capital. Using district-level data on literacy and two different identification strategies, we find railroads had positive effects on literacy, in particular on male and English literacy. We show that railroads increased literacy by raising secondary and elite primary schooling, rather than vernacular primary schooling. Our mediation analysis suggests that non-agricultural income, urbanization, and opportunities for skilled employment are important mechanisms, while agricultural income is not.
Are the preferences of women and men unequally represented in public policies? This simple yet fundamental question has remained largely unexplored in the fast-growing fields of women’s representation and inequality in the opinion-policy link. Our study analyzes gender biases in policy representation using an original dataset covering 43 countries and four decades, with citizens’ preferences regarding more than 4,000 country-year policies linked to information about actual policy change. Our analysis reveals clear and robust evidence that women’s policy preferences are underrepresented compared to those of men. While this skew is fairly modest in terms of congruence, women’s representation is driven mostly by the high correlation of preferences with men. When there is disagreement, policy is more likely to align with men’s preferences. Our analyses further suggest that women’s substantive underrepresentation is mitigated in contexts with high levels of female descriptive representation and labor market participation. In sum, our study shows that gender inequality extends to the important realm of policy representation, but there is also meaningful variation in unequal representation across contexts.
Direct numerical simulations up to Reλ = 1445 show that the scaling exponents for the enstrophy and the dissipation rate extrema are different and depend on the Reynolds number. A similar Reynolds number dependence of the scaling exponents is observed for the moments of the dissipation rate, but not for the moments of the enstrophy. Significant changes in the exponents occur at approximately Reλ ≈ 250, where Reλ is the Taylor based Reynolds number, which coincides with structural changes in the flow, in particular the development of large-scale shear layers. A model for the probability density functions (PDFs) of the enstrophy and dissipate rate is presented, which is an extension of our existing model (Proc. R. Soc. A, vol. 476, 2020, p. 20200591) and is based on the mentioned development of large-scale layer regions within the flow. This model is able to capture the observed Reynolds number dependencies of the scaling exponents, in contrast to the existing theories which yield constant exponents. Moreover, the model reconciles the scaling at finite Reynolds number with the theoretical limit, where the enstrophy and dissipation rate scale identically at infinite Reynolds number. It suggests that the large-scale shear layers are vital for understanding the scaling of the extrema. Furthermore, to reach the theoretical limit, the scaling exponents must remain Reynolds number dependent beyond the present Reλ range.
The moral problem of authority can be expressed as follows: how can authority, and the deference it entails, be compatible with freedom and rationality? The pluralist approach separates political obligation from authority. For pluralists, authority is both unjustifiable and unnecessary, and so legitimate political obligation, including the duty to obey the law, does not entail deference. I argue that it is possible to retain the pluralist commitment to plural grounds of legitimacy, while rebutting the pluralist objections to authority. As a result, whenever authority does have legitimacy, the moral question of authority will demand an answer.
