Interdisciplinary evidence for early domestic horse exploitation in southern Patagonia

The introduction of domestic horses transformed Indigenous societies across the grasslands of Argentina, leading to the emergence of specialized horse cultures across the Southern Cone. However, the dynamics of this introduction are poorly chronicled by historic records. Here, we apply archaeozoological and biomolecular techniques to horse remains from the site of Chorrillo Grande 1 in southern Argentina. Osteological and taphonomic analyses suggest that horses were pastorally managed and used for food by Aónikenk/Tehuelche hunter-gatherers before the onset of permanent European settlement, as early as the mid-17th century. DNA-based sex identifications suggest consumption of both male and female horses, while ceramic residue also shows use of guanaco products. Sequential isotope analyses on horse dentition reveal an origin in southern Patagonia and movement of these animals between the Río Coig and Río Gallegos basins. These results reinforce emerging evidence for rapid Indigenous-mediated dispersal of horses in the Americas and demonstrate that horses catalyzed rapid economic and social transformations.

Social ties and urban settlement intention of rural-to-urban migrants in China: The mediating role of place attachment and the moderating role of spatial pattern

Using nationally representative data from the 2017 China Migrants Dynamic Survey, this study investigated the mediating role of place attachment and the moderating role of spatial pattern in the association between local network ties and urban settlement intentions among rural-to-urban migrants. We found that local ties were positively associated with urban settlement intention measured by permanent settlement intention (PSI) and place attachment served as a mediating mechanism of this relationship. Results from the moderated path analysis showed that spatial pattern of migration positively moderated the linkage between local ties and PSI, indicating that beneficial role of local ties in urban settlement was more pronounced for inter-provincial migrants than for intra-provincial migrants. This study enhances our understanding of the association between social ties and migrant settlement, elucidating the conditions under which these effects are more pronounced in the context of internal migration. We thus call for a more targeted policy design aimed at integrating rural-to-urban migrants into local communities and eliminating the welfare gaps between migrants and local residents through appropriate intervention measures.

Conceptual Architectural Response to Radiation on Mars

Abstract The climatic conditions on Mars are significantly different from those on Earth, which is the main factor affecting the potential architectural solutions on this planet. Above all, high levels of cosmic radiation of solar and extragalactic origin require specific architectural solutions, such as a safe location and sufficient protection, which are determined by a complex set of factors. These factors include the accessibility of building materials on site, the range and predictability of changes in climatic conditions, and human needs. In this article, the significant influence of radiation on architecture, which should be addressed when planning temporary or permanent resilient settlements on Mars, is examined in the case of manned missions to the planet. For this purpose, a comprehensive literature review is conducted, focused on the latest radiation-related discoveries. As the main outcome, two main schematic architectural solutions are proposed as a step toward more advanced projects. In addition, the gaps that need to be filled in the current approach to the design process, related to the insufficiently strong focus on multidisciplinary site analysis with radiation as its main factor (as is necessary for erecting an inhabitable base) are addressed.

The Static and Dynamic Behavior of Steel Storage Tanks over Different Types of Clay Soil

Steel storage tanks are widely used in different fields. Most of these tanks contain hazardous materials, which may lead to disasters and environmental damage for any design errors. There are many reasons which cause the failure of these tanks such as excessive base plate settlement, shear failure of soil, liquid sloshing, and buckling of the tank shell. In this study, five models of above-ground steel storage tanks resting over different types of clay soils (medium-stiff clay, stiff clay, and very stiff clay soils) are analyzed using the finite element program ADINA under the effect of static and dynamic loading. The soil underneath the tank is truly simulated using a 3D solid (porous media) element and the used material model is the Cam-clay soil model. The fluid in the tank is modeled depending on the Navier–Stokes fluid equation. Moreover, the earthquake record used in this analysis is the horizontal component of the Loma Prieta Earthquake. The analyzed tanks are circular steel tanks with the same height (10 m) and different diameters (ranging from 15 m to 40 m). The soil under the tanks has a noticeable effect on the dynamic behavior of the studied tanks. The tanks resting over the medium-stiff clay (the weakest soil) give a lower permanent settlement after the earthquake because of its low elastic modulus which leads to the absorption of the earthquake waves in comparison to the other types of soil. There are 29.6% and 35.6% increases in the peak dynamic stresses under the tanks in the cases of stiff clay and very stiff clay soils, respectively. The maximum values of the dynamic vertical stresses occur at a time around 13.02 s, which is close to the peak ground acceleration of the earthquake.

CARIN' about migrants through news? Linking migrant deservingness to traditional and digital media consumption

AbstractIn recent years, public discourse and political actors have increasingly used a deservingness rhetoric to refer to the arrival and permanent settlement of migrant groups. However, scholars have drawn on the concept of deservingness without developing a clear theoretical framework for it. Following our recent work on the migrant deservingness framework, in the present study we use the CARIN criteria (Control, Attitude, Reciprocity, Identity, Need) to establish the extent to which host nationals in eight nations impose conditions towards accepting permanent settlement among migrants. Specifically, we examine the links of these deservingness perceptions with news media consumption in seven European countries and Colombia using online survey panel data (N = 12,142). Our findings indicate that consuming news via commercial television and in popular newspapers, in particular, is linked to greater conditionality regarding migrant settlement. Consuming public television or quality news sources is only weakly linked to (reduced) conditionality. We discuss these findings using the migrant deservingness framework.

Change and stability of migration intentions. Evidence from Italy

AbstractDue to a lack of relevant data, very few empirical studies have examined the changes in and stability of secondary migration intentions. We aim to fill this gap by analysing return migration intentions among international migrants in Italy. Data are drawn from the cross‐sectional SCIF survey conducted by ISTAT in 2011–2012. Our findings reveal that migration intentions at the beginning of the migratory experience tend to differ from those measured at more advanced migration stages (i.e. at the time of the survey). In particular, intentions to return seem less stable than intentions to stay. When confirming intentions to return or remain, critical factors include financial stability, family situation and ties with the country of origin and destination. Additionally, having an Italian partner, a partner living in Italy, and a positive self‐assessed family financial condition are positively associated with transitioning from a temporary plan to a permanent settlement intention.

A numerical framework for modelling settlements of railway ballast layers

Permanent deformation in ballast layers is a major contributing factor to the railway track geometry deterioration. In spite of a considerable amount of research on understanding and predicting performance of ballast layers, accurately capturing their settlements remains a challenge. In order to contribute to solving this important issue, a new numerical method for predicting ballast settlements is presented in this paper. This method is based on the finite element (FE) method combined with a constitutive model that captures permanent deformation accumulation in unbound materials under cyclic loading. This allows predicting permanent deformations of large structures and at large number of load cycles in a computationally efficient manner.The developed constitutive model is validated based on triaxial test measurements over wide range of loading conditions. Stress state in ballast layers has been examined with a 3D FE model, for several embankment structures and traffic load magnitudes. The determined stress distributions and loading frequencies were used as an input of the constitutive model to evaluate permanent strains and settlements of ballast layer. The influence of embankment structural designs and traffic loading magnitudes on the ballast layers settlements is examined and the results obtained are compared with the existing empirical performance models.

Kabalis / Kabalia Yüksek Yayla Yerleşimlerinde Zeus ve Şimşek Demeti Kabartmaları

The worship of Zeus, the head of the gods of Olympus, is more widespread in rural areas than in urban centers in the Kabalis / Kabalia region. Zeus, who is generally seen in cities for the prosperity and well-being of the city or for amity in treaties, has a different presence in rural areas than the established cult in the cities. Zeus, who is mostly associated with the sky and celestial phenomena, also manifests himself in rural life in agriculture and animal husbandry. In this context, the bust of Zeus and the reliefs, altars and architectural blocks bearing winged or wingless thunderbolt, the attribute of Zeus and recorded in ancient literature, were analyzed on the basis of rural life and especially seasonal migration. In addition to these finds, two altars, one with an inscription, registered in the inventory of the Burdur Archaeological Museum, were also included in the research, and, in relation to rural life and transhumance activities the characteristics related to this deity were investigated. This depiction, which is sometimes seen as a winged thunderbolt and sometimes as a thunderbolt carried by an eagle on the coins of the cities of the Kabalis / Kabalia Region during the Hellenistic Period, appears on rock reliefs, architectural blocks, and altars in the high plateaus, permanent or periodic rural settlements during the Roman Imperial Period. Through the identification of the finds in the region, including those with similar reliefs, a preliminary impression of the epithets with which this deity may have been worshipped has been attempted.

Erosion assessment with Martian dust

Safe and long-lasting extraterrestrial life is based on permanent human settlements on other planets or satellites, which imposes reliable operating life and reduces overhaul and maintenance of systems and structures. The condition for the safety and long life of components is dramatically connected to the environment in which they operate. Temperature, pressure, and contamination by suspended particles represent the most significant safety and continuous operability obstacles. This analysis assesses the erosion behavior of engineering materials, commonly used in components and devices designed for ground and aerial Martian operations, against Martian simulant dust. The erosive detriment generated by Martian dust has been compared to that occurs with the terrestrial soil, assessing the relationship to predict the life's component on the Martian surface.

The developmental migration state

ABSTRACT What drives some states to liberalise immigration policies while others resist doing so? Why do states expand rights for some migrants and not for others? Building on Hollifield’s [(2004). ‘The Emerging Migration State’. International Migration Review 38 (3): 885–912] theory of the migration state, this article explores how the process of political economic development in Japan, South Korea, and Taiwan shaped their citizenship regimes and, later, their immigration policies. We argue that the specific patterns of migration management in East Asian democracies – characterised by partially open borders and discrete institutionalised rights for specific subcategories of migrants – is not a reflection of an incomplete liberal migration state but rather, migration control by (formerly or contemporary) developmental states that have historically prioritised economic development, social stability, and national security over democracy and equality. Based on an analysis of archival, policy, and legal documents collected in Japan, South Korea, and Taiwan from 2010 to 2019, this article analyzes the emergence of the ‘developmental migration state’ that correlates migrants’ access to rights and permanent settlement with their utility towards national developmental goals.

Moving to Mars: The Feasibility and Desirability of Mars Settlements

The on-going space settlement debate has raised questions whether it is possible to settle other planets, and if it was, is it something humans should do. The problem with this space ethical discussion is that it can easily become too vague. To avoid this problem, we suggest a framework for identifying relevant variables that affect the feasibility constraints and desirability factors of establishing space settlements. The variables we focus on include the settlement stage, scale and time frame. Based on the relevant literature, we take mission cost, survival, habitation, water, in situ resources for food, oxygen and fuel energy and dependence on Earth as feasibility constraints that are relevant for the framework. None of them are hard constraints, but rather soft feasibility constraints that make it difficult to establish a permanent human settlement on Mars in the near- to medium-term future. However, in the past, humanity has achieved goals that first seemed infeasible. To justify the costs and effort, the goal must be highly morally desirable. We discuss five different desirability factors that could help justify the effort but as each framework has unique feasibility constraints, not all of these factors are sufficient or necessary to justify this effort. We argue that some of the desirability factors prominent in space ethical literature are not sufficient or necessary in our framework, and thus, we conclude that the normative grounds for establishing a permanent Mars settlement in the foreseeable future are weak.

From circular to permanent: The economic assimilation of migrants during Spain's rural exodus, 1955–73

AbstractCircular migration has played a substantial role in the assimilation process of rural–urban migrants in Spain across the twentieth century. This paper analyses the short‐term impact of the temporariness of this type of migration in the economic assimilation of migrants during the rural exodus, 1955–73. More specifically, I study this process in one key scenario – the Spanish tourism boom. Using a novel micro‐dataset, results show that the temporariness was a key factor that constrained the capacity of migrants to achieve income growth. Thus, the incentives to persist with circular migratory movements and the socio‐economic constraints on permanent settlement had significant adverse consequences. These migrants sorted into lower‐income occupations and had lower incentives and chances to acquire host‐specific human and social capital in comparison with permanent migrants. As a result, circular migrants registered lower occupational attainment leading to a higher income gap with natives and permanent migrants as the years of circular migration increased in number. These results indicate that most migrants had fewer chances than natives of taking advantage of the process of rapid structural change not solely because of lower human and social capital factors but also because of the temporariness of their migration.

An integrated archaeo-palaeoenvironmental approach to the study of human-environment relationships in the Wierzchowo Lake microregion (Northern Poland) during the Mid- to Late Holocene

The area surrounding Wierzchowo Lake, located in the central part of Pomerania (Northern Poland), is of particular interest from the point of view of the development of past settlements. Archaeological data have revealed human activity during various periods, ranging from the Palaeolithic through the Modern Period. This may suggest the relative and long-term attractiveness of this area. Among archaeological sites from this microregion, a monumental, well-preserved hillfort located in the Wierzchowo Lake peninsula stands out. Although limited excavations were carried out and numerous archaeological materials were collected, its origin remains unclear. Unfortunately, this hillfort could not be properly investigated during the excavations, due to the conservation conditions resulting in a high level of administrative protection. Having these limitations in mind, it was decided to conduct a palaeoenvironmental investigation in the vicinity of this hillfort and correlate its results with the extensive archaeological information available for this area. An investigation based on pollen, charcoal, and geochemical analysis of the lake sediments and their juxtaposition with the available archaeological record, a broad insight into the past of this region, and the nature of the relationship between people and the natural environment were revealed. The first traces of permanent settlement have been linked to the Funnel Beaker culture. A strong increase in human impact within the microregion and important changes in local vegetation (e.g., deforestation, the spread of ruderal habitats) have been associated with the activities of Lusatian culture groups at the end of the Late Bronze Age. A significant transformation of the natural environment and modification of farming practices has been recorded during the Roman Period (Wielbark culture communities) and Medieval Times (Slavic culture). Changes in vegetation composition have also been related to climatic fluctuations around 850 BCE, during the Migration Period and Little Ice Age, when temporary settlement regressions were observed.

Axial cyclic performance of a jacked pile in structured clays: A semi-analytical solution approach

Cyclic loads resulting from environmental factors such as wind, waves, trains, and construction activities pose a potential hazard to the stability of piled structures. These loads can cause the performance degradation of piles, including cumulative settlement and weakening of bearing capacity. This paper presents a semi-analytical solution for evaluating the axial cyclic behavior of jacked piles in structured clays. The solution employs enhanced nonlinear load-transfer models that effectively capture the stress-strain hysteresis and interfacial cyclic degradation characteristics. The key factors influencing pile behaviors are incorporated within the analytical approach, encompassing pile installation, subsequent soil equalization, and the static and cyclic loading encountered during service. The validity of the current solution is established through model pile tests conducted in artificially structured clays under static and cyclic loading conditions. Extensive parameter studies are performed using the proven theoretical approach to emphasize the influence of soil structure and cyclic loading on pile behavior. The results demonstrate a favorable agreement between the theoretical and measured values in static and cyclic pile response analyses. Compared with the response of jacked piles in reconstituted clays, the pile response in structured clays with a cement content of Aw = 4%, including penetration resistance, final ultimate bearing capacity, and the convergence speed of permanent settlement, has been substantially improved. The parameter studies indicate that soil structure and cyclic loading patterns significantly influence the axial cyclic performance of jacked piles in natural clays.

Dynamic behaviors of frozen silt under repeated traffic loading

The temperature state of warm permafrost is in the negative temperature near-phase-transition interval and thus is extremely sensitive to small fluctuations of the heat and stress environment. The dynamic load induced by the vehicle operation not only changes its magnitude cyclically, but also its principal stress direction (PSD) consistently changes rotationally. However, the existing conventional dynamic research methods can only simulate the cyclic stress environment with constant PSD, which is very different from the stress environment induced by locomotive operation, and thus the conventional dynamic research results are bound to be difficult to accurately reflect the influence of the stress field induced by vehicle operation on the development law of warm permafrost permanent settlement deformation. Therefore, in this paper, a series of dynamic studies were carried out for the Qinghai-Tibet silt at −2 °C by simulating the cardioid-shaped stress path induced during the operation of a heavy-duty locomotive using a frozen hollow cylinder apparatus. It is found that the rotational effect of the principal stress direction under the conditions of the cardioid-shaped stress path (CSSP) action accelerates the development of vertical permanent deformation in the frozen soil. The main reason that caused the axial strain increases advantage is the rotation of principal stress direction can accelerate the viscous energy dissipation during dynamic loading process. According to the law of axial strain development in the high-temperature frozen soil under the conditions of different CSSP action, an empirical model of permanent deformation development in high-temperature frozen soil considering the PSD rotation effect was established, and it was found by this model calculation that under the general condition of heavy-load locomotive operation, compared with the conventional research method without considering the PSD rotation, the axial cumulated strain in high-temperature frozen soil increased by 33.3% after considering the rotation effect in the PSD.

Settling down in Southwest Asia: the Epipalaeolithic-Neolithic transformation

Permanent settlement began in southwest Asia across the end of the Pleistocene (the Epipalaeolithic) and the beginning of the Holocene (the Neolithic). Aggregation represents a transformation of the cultural niche, involving major social and cultural innovations and profound developments of the strategies of subsistence. At first, the scalar stress of living in large, permanent communities was diffused through corporate effort in the construction and maintenance of monumental communal buildings, a complex material symbolism, and increasing intensity of communal rituals; participation demonstrated commitment and conformity to community norms. As cultivated crops and managed herds of sheep and goat gradually became the predominant source of subsistence, the old sharing ethos was overtaken by the household as the central socio-economic unit; the household became the focus for ritual and symbolism. As population aggregations grew larger, their supra-regional networks of socio-economic sharing and exchange also became more complex, extensive and intensive. The new cultural niche based on networked aggregations produced a marked acceleration in both the rate of cultural accumulation and the rate of demographic growth. At the end of the Neolithic, plow-agriculture began in place of horticulture; there are the first signs of mixed agro-pastoral economies, the marking of private property, new technologies (ceramics and copper metallurgy), and, in southern Iraq, irrigation agriculture. At this time, too, the accelerating expansion of the population of farmers is marked by the appearance of their new settlements in all directions.

Identifying seasonal settlement sites and land use continuity in the prehistoric southern Siberian steppe – Zhelvak 5 (Tuva)

The identification of camp sites of Iron Age cultures on the Eurasian steppes has long been a problem as the traces of seasonal settlements are faint and often destroyed by agricultural activities. Recent research has found increasing evidence for less mobility and a larger role farming played in the mixed and locally adapted economies of peoples on the steppes. Here we present the results of the investigation of a settlement from the Uyuk Valley and contextualize it with data for seasonal camp sites and settlements in Iron Age South Siberia. Contrary to the long-held beliefs that Iron Age herding societies were truly nomadic and did not establish permanent settlements, archaeological research in South Siberia is gradually starting to reveal a different picture. Remote sensing and on-ground surveys uncovered six Scythian-period settlement sites in Tuva occupying southern hill slopes in sheltered topographic settings. Excavations at Zhelvak 5 revealed a stratified site with materials from the Bronze Age to the Late Iron Age and beyond. The archaeological material speaks towards continuity of economic exploitation of this landscape and the establishment of seasonal camp sites in the same place over a prolonged period of time.

Overconsolidated Stress and Strain Condition of Pavement Layers as a Result of Preloading during Construction

The stiffness and resilient behavior of soils are essential input properties when designing pavements. There are many material models that take into account the stress dependency of stiffness. In pavements, horizontal stresses generally differ from conventional soils because of the preloading of the pavement during construction. In this research, standardized pavement cross sections were analyzed using finite element software with advanced soil constitutive models, and equations describing their behavior were calibrated with the back-analysis of in-situ and laboratory measurements. The pavement was modelled as comprising 4 layers: asphalt pavement, well graded crushed stone base course, granular subbase course and fine-medium sandy subgrade. The ratio of horizontal and vertical stresses σ3/σ1 and strains ε3/ε1 were investigated and assessed in the function of depth and loading, and recommendations are given for the description of these functions. The recommendations give useful input data for future practical applications such as simplified calculation methods that are capable of determining the permanent settlement beneath flexible pavements without the use of finite element methods.

Role of Social Ties in Long-Term Settlement of Highly Skilled Migrants in Finland

Highly skilled migrants are often assumed to move from place to place at low thresholds, following the best job offers and easily integrating into new host societies. This study problematizes these as-assumptions and provides empirically based knowledge on the integration of highly skilled migrants working in the ICT sector in Finland, with a particular focus on social relations and plans for long-term or permanent settlement. The study investigates migrants’ social relations in their work environment and free time, taking into account the role of migrant communities as well as families and relatives in Finland and abroad. Finland forms an interesting research context because of its linguistic isolation, remoteness and increasing interest in attracting highly skilled migrants. The investigation adds evidence on the central role of social ties in migration decisions and long-term settlement of highly skilled migrants. 

When the Archaeologists Leave

AbstractThe Hacienda El Progreso functioned as an important Ecuadorian agro-industrial enterprise in the late nineteenth century. Operating out of San Cristóbal Island in the Galápagos archipelago, the plantation exported refined sugar, coffee, cattle products, and other goods to national and international markets. From its beginnings in the 1860s, the plantation established the first permanent human settlement on the island, and long after its demise in the 1930s, it continues to exert an important influence in local culture. Contemporary communities of San Cristóbal are shaping their identities based on the historical importance of the hacienda. The summer of 2018 was our last field season. From its start, the Historical Ecology of the Galápagos Islands project involved close participation with communal authorities and town leaders to investigate the island's human past. In this article, we discuss legacy and services of our project in the contemporary setting of Galápagos. We examine the relevance and contributions of our project to education, heritage policies, and the local economy. We discuss lessons learned from interactions and collaborations between archaeologists and the local community, and we evaluate the consequences of implementing an archaeological project on a remote environmental sanctuary where interest in human history can collide with the agendas of nature conservation and a lucrative ecotourism industry.
