Abstract:

Studies of the peopling of the Americas have focused on the timing and number of initial migrations. Less attention has been paid to the subsequent spread of people within the Americas. We sequenced 15 ancient human genomes spanning from Alaska to Patagonia; six are ≥10,000 years old (up to ~18× coverage). All are most closely related to Native Americans, including those from an Ancient Beringian individual and two morphologically distinct “Paleoamericans.” We found evidence of rapid dispersal and early diversification that included previously unknown groups as people moved south.

Abstract:

Dramatic events in human prehistory, such as the spread of agriculture to Europe from Anatolia and the late Neolithic/Bronze Age migration from the Pontic-Caspian Steppe, can be investigated using patterns of genetic variation among the people who lived in those times. In particular, studies of differing female and male demographic histories on the basis of ancient genomes can provide information about complexities of social structures and cultural interactions in prehistoric populations. We use a mechanistic admixture model to compare the sex-specifically–inherited X chromosome with the autos

However, animals must make compromises to maximize survival and compensate for the risks associated with long-distance movement.

Abstract In the 1980s, over a million Iranian asylum seekers transited through Turkey on their way west, most moving through irregular migration channels. While much has been made of Turkey’s evolving role in more recent refugee crises, this literature neglects the importance of the 1980s Iranian refugee migrations in shaping the global refugee system. By connecting the story of the international human rights movement to the Ankara office of the United Nations High Commissioner for Refugees (UNHCR), this paper emphasizes the role of non-state actors.

This study examines early cultural and civilizational interactions between Libya and the Nile Valley during prehistoric times, emphasizing the role of climatic changes and human migrations. Archaeological evidence indicates that Libya saw significant cultural development from the Paleolithic era, with civilizations like the Aterian and Capsian excelling in stone tool production and pottery. These cultures shared ties with the Nile Valley, as demonstrated by similar artifacts found in both regions. Environmental changes, particularly desertification, drove Libyan migrations toward the Nile Vall

Keywords of Identity, Race, and Human Mobility analyses a selection of terms that were central to the conceptualisation of identity, race, migration, and transculturality in the early modern period. In many cases, the concepts and debates that they embody – or sometimes subsume – came to play crucial roles in the articulation of identity, rights, and power in subseque

Early forecasting of bird migration patterns has important application for example in reducing avian biodiversity loss. An estimated 100 million to 1 billion birds are known to die yearly during migration due to fatal collisions with human made infrastructures such as buildings, high tension lines, wind turbines and aircrafts thus raising a huge concern for conservationists. Building models that can forecast accurate migration patterns is therefore important to enable the optimal management of these critical infrastructures with the sole aim of reducing biodiversity loss.

Abstract:

Recent advances in nanoscience offer great promise for the nanomedicine sector. These advances in the nanotechnology field will undoubtedly increase both human and environmental exposures to engineered nanomaterials. Whether these exposures pose a significant risk remains uncertain. Despite recent collective progress there remain gaps in our understanding of the nanomaterials physiochemical properties that drive or dictate biological compatibility. The development and implementation of rapid relevant and efficient testing strategies to assess these emerging materials prior to large-scale expos

Abstract:

Abstract The standard float mud cap drilling (FMCD) was adapted to the dual gradient mud cap drilling (DGMCD), a fit-for-purpose contingency technique for drilling under the potential of total fluid loss scenario in the Brazilian pre-salt carbonates, which can present vugs and natural fractures. The primary barrier is still the hydrostatic column, achieved by two different fluids in the annular space: a seawater cap and a heavy annular mud (HAM). While the HAM is constantly injected in the annulus to prevent gas migration, keeping the well dynamically dead while drilling, the sacrificial fluid

Abstract:

In 1997, the Mexican government designed the conditional cash transfer program Progresa, which became the worldwide model of a new approach to social programs, simultaneously targeting human capital accumulation and poverty reduction. A large literature has documented the short and medium-term impacts of the Mexican program and its successors in other countries. Using Progresas experimental evaluation design originally rolled out in 1997-2000, and a tracking survey conducted 20 years later, this paper studies the differential long-term impacts of exposure to Progresa. We focus on two cohorts o

Abstract:

As the country witnesses a steady export of its human resources, it becomes imperative to explore not only the immediate impacts of labor migration on the Philippine economy but also its long-term consequences on both the overseas Filipino workers and the families they leave behind. This study examines the various effects of labor migration on OFWs and their families, including the economic benefits and social costs (e.g., family dynamics, child outcomes in terms of labor, health, education) of the diaspora, and what the government has done to assist these modern-day heroes.

Abstract:

This report aims to present findings of the research conducted in Poland within the Work Package 1 of the Welcoming Spaces project, namely “Welcoming spaces” in relation to economic viability, social wellbeing and political stability in shrinking regions. The main aim of the mentioned research was to examine how welcoming initiatives are organised and implemented in the selected shrinking localities in Poland. In particular, the creation of welcoming initiatives concerning social wellbeing, economic viability and political stability was assessed. To accomplish this objective, five localities w
