Examination of plant microfossils (phytoliths and starch granules) preserved in dental calculus allows for the direct identification of some components of prehistoric diets. In this article, the authors present the results of microfossil analysis of dental calculus from wild and domestic animals at the Late Neolithic site of Kangjia in the Central Plains, an area critical in the emergence of early Chinese states. Consumption of cooked plant foods by domestic pigs and dogs, and of domestic crops by wild animals, at this site hints, the authors argue, at an interdependent relationship between animal management, agricultural production and ritual practices that contributed to the political transformations of Late Neolithic China.
A “sink or swim” approach has been considered the only way to learn how to conduct empirical research; this should not be the case. Empirical research can be challenging for methodological, practical and ethical reasons; thus there should be detailed and systematic reporting on the methodology adopted. The absence of studies documenting the experiences of researching law implies that important lessons gained by one cohort are not readily accessible in a systematic way for the next. This article presents the methodology of research that was conducted in a conflict area in Nigeria during the pandemic; it aims to provide detailed reporting on the research and highlight the challenges. It offers lessons to future researchers undertaking socio-legal research in a conflict zone, during a pandemic or both. It contributes to the body of knowledge that presents not just what is being done in legal research but how, in order to develop “robust and cumulative scholarly traditions”.
The intensity of changes in the population dynamics of the Early Neolithic (ca. 6250–5300 cal BC) communities in the Central Balkans was addressed by estimating the growth rate values. The Bayesian approach (Crema and Shoda 2021) of estimating intrinsic growth rates by fitting different models of population growth was applied to radiocarbon dates from the Early Neolithic sites in Serbia. We explored two possible episodes of population growth based on the results of the population dynamics reconstruction using the summed calibrated radiocarbon probability distributions (SPD) method. The results have shown that, within the first episode of growth, the intrinsic growth rate mean values are higher than the estimated continental average (between 1% and 2%). The results indicate a sudden and fast rise in population size, possibly due to the influx of the new population settling in the region at the beginning of the Neolithic. Lower values for the second episode could indicate more gradual population growth due to the mechanisms associated with the Neolithic Demographic Transition and the rise in fertility.
Nonlinear machine learning for turbulent flows can exhibit robust performance even outside the range of training data. This is achieved when machine-learning models can accommodate scale-invariant characteristics of turbulent flow structures. This study presents a data-driven approach to reveal scale-invariant vortical structures across Reynolds numbers that provide insights for supporting nonlinear machine-learning-based studies of turbulent flows. To uncover conditions for which nonlinear models are likely to perform well, we use a Buckingham-Pi-based sparse nonlinear scaling to find the influence of the Pi groups on the turbulent flow data. We consider nonlinear scalings of the invariants of the velocity gradient tensor for an example of three-dimensional decaying isotropic turbulence. The present scaling not only enables the identification of vortical structures that are interpolatory and extrapolatory for the given flow field data but also captures non-equilibrium effects of the energy cascade. As a demonstration, the present findings are applied to machine-learning-based super-resolution analysis of three-dimensional isotropic turbulence. We show that machine-learning models reconstruct vortical structures well in the interpolatory space with reduced performance in the extrapolatory space revealed by the nonlinearly scaled invariants. The present approach enables us to depart from labelling turbulent flow data with a single parameter of Reynolds number and comprehensively examine the flow field to support training and testing of nonlinear machine-learning techniques.
Across countries and over time, support for economic globalization is strongest among individuals with the highest levels of education. Yet despite long-lasting debates on the sources of this correlation, reliable evidence that isolates the causal effect of education from the nonrandom selection of individuals into education is lacking. To address this fundamental issue, I exploit compulsory-schooling reforms that increased the minimum school-leaving age in eighteen countries. Employing a fuzzy regression discontinuity design, I find that the reform-induced added years of education substantially and durably increased support for trade liberalization. And using new data on the content of school curricula, I find that the effect of schooling largely stems from instilling tolerance and pluralism in citizens and reducing the perceived cultural threat of globalization. In contrast, there is little evidence that the effect of schooling reflects the distributive consequences of international trade, separating globalization winners and losers.
Daqingshanite in the Kamthai REE deposit (India) occurs as two paragenetic types: primary granular coarse grained crystals coexisting with primary carbocernaite, baryte and bastnäsite; and as aligned micro-ovoid globules within clasts of Sr-bearing calcite. Carbocernaite forming trellis-type lamellae in some of these calcite clasts do not represent exsolution and are considered as replacement textures as they formed subsequent to daqingshanite. The origins of the textural relations of the microglobules of daqingshanite to their host Sr-calcite cannot be unambiguously determined, although an exsolution origin is not considered feasible. The textures are similar to those of ‘chalcopyrite disease’ and as such could be interpreted as replacement features formed in a low temperature carbothermal environment which should facilitate replacement. Given that daqingshanite is an early crystallising phase it is also possible that cotectic crystallisation with Sr-calcite occurred, followed by subsolidus re-equilibration with recrystallisation along specific crystallographic planes in the calcite. The Kamthai REE deposit is best described as a low temperature carbothermalite microbreccia consisting of a wide variety of clasts resulting from the autobrecciation of rocks formed during, and after, the magmatic to carbothermal transition of an undetermined parental calcite carbonatite-forming magma. Many clasts have been replaced by late stage La-enriched carbothermal fluids mixed with exogenous water during the final low-temperature stage of evolution of the deposit.
Evaporation of multicomponent droplets is important, albeit complex, in a wide range of applications, and requires a careful investigation. We investigate experimentally and numerically the evaporation characteristics of spherical, ethanol–water droplets with different initial concentration ratios in the acoustic levitation field. Imaging techniques and infrared thermometry are used for acquiring volume and surface temperature variations of droplets, reflecting their mass and heat transfer characteristics. Numerical simulations are conducted using modified parameters based on a theoretical model to consider the effect of the acoustic field. The calculation results show good agreement with the experimental data. The concentration and temperature distribution within the droplet is further investigated based on the numerical results.
We explore when the silting-discreteness is inherited. As a result, one obtains that taking idempotent truncations and homological epimorphisms of algebras transmit the silting-discreteness. We also study classification of silting-discrete simply-connected tensor algebras and silting-indiscrete self-injective Nakayama algebras. This paper contains two appendices; one states that every derived-discrete algebra is silting-discrete, and the other is about triangulated categories whose silting objects are tilting.
Ausgehend von der kulturwissenschaftlichen Forschung zu Familienalben und deren Gemeinsamkeiten mit dem Neuen Testament lädt dieser Beitrag dazu ein, darüber nachzudenken, was sich verändert, wenn wir die Fragen der Einführung in das Neue Testament durch die Brille der Theorie des sozialen Gedächtnisses betrachten. Aufbauend auf Forschungsergebnissen der Oral History und kulturwissenschaftlichen Gedächtnistheorie wird argumentiert, dass die allgemeine Einleitung in den Bereich des kulturellen Gedächtnisses und die spezielle Einleitung in den Bereich des sozialen/kollektiven Gedächtnisses fällt. Beide sind durch den Floating Gap getrennt, was die vielfach wahrgenommenen Veränderungen in der ersten Hälfte des zweiten Jahrhunderts erklärt. Im nächsten Schritt wird ein Modell, das auf dem Dreigenerationengedächtnis, der Generational Gap (nach einer Generation), der Floating Gap (nach 3-4 Generationen) und den ersten Generationen von Jesus-Anhängern aufbaut, mit Vorschlägen zur Datierung neutestamentlicher Bücher aus der Einleitungswissenschaft ins Gespräch gebracht. Es zeigt sich, dass die vor und nach dem Generational Gap verwendeten Genres je unterschiedliche Eigenschaften haben, die den Erwartungen an Medien des sozialen und kollektiven Gedächtnisses entsprechen. Der Beitrag schließt mit allgemeinen Fragen zu Medien und Medienwandel im Neuen Testament, d.h. Mündlichkeit und Schriftlichkeit, identische Texte und Textkritik, dem Kanon als primärem Kontext, der Ausweitung des Geltungsbereichs sowie fluiden Gattungen, und kommt zu dem Schluss, dass kulturwissenschaftliche Gedächtnistheorie in der Tat neue Perspektiven für die Einleitungswissenschaft bietet.
As a field of practice, international human rights law (IHRL) is in constant motion. The four books under review explore the legal, political, and civic dynamics that continuously shape and reshape this vibrant area of law. In this Essay, I underscore two important trends in contemporary IHRL scholarship that these books highlight. First, these works share a strong emphasis on agency, understood as human action that makes a difference in the world, be it the agency of individuals, domestic civil society organizations, transnational organizations, or courts. Highlighting agency, rather than overarching political, economic, and social structures, in turn shifts the attention from human rights law and doctrine “in the books” to an understanding of human rights law as a purposive and dynamic practice.
