While the concept of economic nationalism is frequently deployed it is often poorly defined, posited as the cause of protectionism in some cases while providing a rationale for liberalization in others. This Element provides a more rigorous articulation by analyzing variation in foreign investment regulation in postwar Brazil and India. Conventional approaches cite India's leftist “socialism” and Brazil's right-wing authoritarianism to explain why India resisted foreign direct investment (FDI) while Brazil welcomed foreign firms. However, this ignores puzzling industry-level variation: India restricted FDI in auto manufacturing but allowed multinationals in oil, while Brazil welcomed foreign auto companies but prohibited FDI in oil. This variation is inadequately explained by pluralist theories, structural-material approaches, or constructivist ideas. This Element argues that FDI policies were shaped by contrasting colonial experiences that generated distinct economic nationalisms and patterns of industrialization in both countries.

According to Kant, citizenship amounts to freedom (Freiheit), equality (Gleichheit), and civil self-sufficiency (Selbständigkeit). This Element provides a unifying interpretation of these three elements. Vrousalis argues that Kant affirms the idea of interdependent independence: in the just society, citizens have independent use of their interdependent rightful powers. Kant therefore thinks of the modern state as a system of cooperative production, in which reciprocal entitlements to one another's labour carry a justificatory burden. The empirical form of that ideal is a republic of economically independent commodity producers. It follows that citizenship and poverty, for Kant, are inextricably connected. Vrousalis explains how Kant's arguments anticipate Hegel's discussion of the division of labour, Marx's account of alienated labour, and Rawls' defence of a well-ordered society.

Transparency has become a ubiquitous presence in seemingly every sphere of social, economic, and political life. Yet, for all the claims that transparency works, little attention has been paid to how it works – even when it fails to achieve its goals. Instead of assuming that transparency is itself transparent, this book questions the technological practices, material qualities, and institutional standards producing transparency in extractive, commodity trading, and agricultural sites. Furthermore, it asks: how is transparency certified and standardized? How is it regimented by 'ethical' and 'responsible' businesses, or valued by traders and investors, from auction rooms to sustainability reports? The contributions bring nuanced answers to these questions, approaching transparency through four key organizing concepts, namely disclosure, immediacy, trust, and truth. These are concepts that anchor the making of transparency across the lifespan of global commodities. This title is also available as Open Access on Cambridge Core.

Against the backdrop of worsening tensions across the Taiwan Strait, this Element analyzes the positions and policies vis-à-vis Taiwan of six major democratic US treaty allies-Japan, Australia, South Korea, the United Kingdom, France, Germany-and the European Union. Historically and today, these US partners have exercised far greater agency supporting Taiwan's international space and cross-Strait stability-in key instances even blazing early trails Washington would later follow-than the overwhelmingly US-centric academic and policy discourse generally suggests. Decades ago, each crafted an intentionally ambiguous official position regarding Taiwan's status that effectively granted subsequent political leaders considerable flexibility to operationalize their government's 'One China' policy and officially 'unofficial' relationship with Taiwan. Today, intensifying cross-Strait frictions ensure that US allies' policy choices will remain critical factors affecting the status quo's sustainability and democratic Taiwan's continued viability as an autonomous international actor.

This paper presents the design and characterization of a unit cell for dual-polarized liquid crystal (LC)-based reconfigurable intelligent surfaces (RIS), as well as an efficient, full-wave simulation methodology for the far-field beam-steering capabilities of large-scale LC-RIS. Within this framework, the unit cell relies on defected delay lines with a 4.6 μm thin LC layer aperture coupled to a patch antenna. This delay line architecture aims towards simultaneous optimization of loss, bandwidth and response time. Full-wave simulations of the unit cell in a periodic environment show an operating frequency between 26.5 and 29.5 GHz with wide angle radiation. Measurements of the unit cell in a 3 $\times$ 3 rectangular grid exhibit wideband impedance matching and overall good agreement with simulations. Furthermore, a simulation methodology is introduced that evaluates large-scale LC-RIS far-field beam-steering capabilities without requiring full-wave simulations of the entire structure, but just few unit cells. Within this scope, the LC-RIS achieves a maximum efficiency of 20.8% with a beam-steering range from −48° to +48°, despite the use of a lossy glass substrate and gold as a conductor. It exhibits a minimum bandwidth of 8.2% for an efficiency of at least 10% across all analyzed steering angles in E-Plane and H-Plane.
This Element explores the transformative impact of integrating service design principles into public management and administration, championing a user-centred approach and co-design methodology. By reviewing existing literature, the authors define the scope and applications of service design within public administration and present three empirical studies to evaluate its implementation in public services. These studies reveal a trend towards embracing co-design and digital technologies, advancing a citizen-centred strategy for public service design. This approach prioritizes value creation and responsiveness, highlighting the importance of involving users and providers in the development of services that meet changing needs and promote inclusion. Combining theoretical insights with practical solutions, the Element offers a comprehensive framework for public management research. It highlights the need for ongoing engagement and integration of user experiences, presenting an effective strategy to navigate the complexities of public service design.

We consider the flow of a viscous fluid through a two-dimensional symmetric cross-slot geometry with sharp corners. The problem is analysed using the unified transform method in the complex plane, providing a quasi-analytical solution that can be used to compute all the physical quantities of interest. This study is a novel application of this method to a complicated geometry featuring multiple sharp corner singularities and multiple inlets and outlets. Our approach offers the advantage of resolving unbounded domains, as well as providing quantities of interest, such as the velocity and stress profiles, and the Couette pressure correction, from the solution of low-order linear systems. Our results agree well with the existing literature, which has largely used truncated bounded geometries with rounded or curved corners.
To evaluate eligibility and participation in nutrition assistance programs (Supplemental Nutrition Assistance Program [SNAP] and Woman, Infants, and Children [WIC]) among transgender and gender diverse (TGD) adults in the United States (U.S.) and to capture their experiences when accessing food benefits.
Design:
This was a cross-sectional analysis of the U.S. Transgender Survey (USTS) dataset– the largest survey of TGD adults in the U.S. SNAP and WIC participation and experiences when visiting the public assistance office were reported using descriptive statistics; stratified analyses were conducted based on race using multivariate logistic regression modeling.
Setting:
The USTS was completed electronically in the United States.
Participants:
27,715 TGD adults.
Results:
Approximately 40.9% of the full sample were SNAP eligible, yet only 30.6% of those eligible were receiving the benefit; 0.45% of the sample reported receiving WIC. TGD adults avoided the public assistance office because they feared being mistreated (3.2%), were identified as transgender (46.2%), were denied equal treatment (6.5%), or were verbally harassed (5.2%). People of color were more likely to be denied equal treatment and verbally harassed at the public benefits office than white peers. The impact of age, education level, employment status, relationship status, and census region varied within each racial group.
Conclusions:
Far more TGD adults need food assistance compared to the general population, yet fewer are receiving the benefit. Culturally informed interventions are urgently needed to resolve the root causes of food insecurity, increase SNAP participation and address the negative experiences of TGD adults when accessing food benefits.
Aspects of the school food environment can influence food purchasing and consumption among adolescents, particularly those without access to a school meal program. Our objective was to describe and compare food vendors of junior high schools in Ghana.
Design:
We conducted structured observations of food vendors within a 0.25-km radius of 8 junior high schools. We compared foods sold and hygiene practices by vendor and community characteristics, such as on vs off campus location, urban vs rural, and predominant income generating activity of the community. We also assessed the relationship between adolescent diet quality (food group diversity, all-5, NCD-protect, and NCD-risk scores) and procurement method for foods consumed during the school day.
Setting:
Cape Coast and Elmina, Ghana
Participants:
200 randomly selected students.
Results:
Of 265 identified vendors, 25.3% sold foods on-campus. On-campus vendors were less likely to sell branded snacks (19.4% vs. 33.8%, p=0.001), and beverages (17.9% vs. 35.4%, p=0.008) and more likely to sell prepared dishes (53.7% vs. 31.8%, p=0.001) than off-campus vendors. Vendors practiced an average of 38.8% of applicable food hygiene practices, which did not differ by on- or off- campus location. In the previous month, 59.4% of students most often purchased food on campus. There were no significant relationships between method of food procurement and diet quality.
Conclusion:
Many adolescents purchased food at school and there were differences in foods sold by on- and off campus vendors. School policies may be a promising avenue to alter food environments for adolescents.
We present a framework to calculate the scale-resolved turbulent Prandtl number ${\textit{Pr}}_t$ for the well-mixed and highly inertial bulk of a turbulent Rayleigh–Bénard mesoscale convection layer at a molecular Prandtl number of ${\textit{Pr}}=10^{-3}$. It builds on Kolmogorov’s refined similarity hypothesis of homogeneous isotropic fluid and passive scalar turbulence, based on log–normally distributed amplitudes of kinetic energy and scalar dissipation rates that are coarse-grained over variable scales $r$ in the inertial subrange. Our definitions of turbulent (or eddy) viscosity and diffusivity do not rely on mean gradient-based Boussinesq closures of Reynolds stresses and convective heat fluxes. Such gradients are practically absent or indefinite in the bulk. The present study is based on direct numerical simulation of plane-layer convection at an aspect ratio of $\varGamma =25$ for Rayleigh numbers $10^5\leqslant Ra\leqslant 10^7$. We find that the turbulent Prandtl number is effectively up to four orders of magnitude larger than the molecular one, ${\textit{Pr}}_t\sim 10$. This holds particularly for the upper end of the inertial subrange, where the eddy diffusivity exceeds the molecular value, $\kappa _e(r)\gt \kappa$. Highly inertial low-Prandtl-number convection becomes effectively a higher-Prandtl-number turbulent flow, when turbulent mixing processes on scales that reach into the inertial range are included. This might have some relevance for prominent low-Prandtl-number applications, such as solar convection.
This study documents and analyzes arthropod trackways from the Upper Cretaceous Wapiti Formation, located in west-central Alberta, Canada. In general, the ichnotaxonomy of arthropod trackways is problematic due to inconsistent use of diagnostic criteria in previous studies. Thus, the trackways from the Wapiti Formation are described following recently defined criteria to facilitate future ichnotaxonomic reevaluations. Judging primarily from the number and morphology of the imprints and the symmetry of the track series, the trackways are identified as Octopodichnus cf. O. raymondi Sadler, 1993. Other relevant track attributes include heteropody and great imprint depth. The mudstone slabs bearing the trackways also contain other well-preserved invertebrate trace fossils along with abundant silicified plant material. The silicified plant fragments, taken together with bentonite overlying the trace-bearing surface, suggest volcanic ash played a role in preserving the trackways. The associated traces include burrows, fecal mounds, and surficial marks and contribute to a diverse invertebrate trace-fossil assemblage. The Wapiti Formation trackways are attributed to crayfish or similar decapods and were emplaced in a succession interpreted to have been deposited in a swampy floodplain environment. By contrast, previously described examples of Octopodichnus have typically been attributed to arachnids in aeolian/desert environments. This paper expands the ichnological record of crayfish-like arthropods from the Late Cretaceous and contributes to the underexplored invertebrate fossil record of the Wapiti Formation and, more broadly, Cretaceous strata in the Western Canada Sedimentary Basin.
