Back to the future: The advantage of studying key events in human evolution using a new high resolution radiocarbon method
Radiocarbon dating is the most widely applied dating method in archaeology, especially in human evolution studies, where it is used to determine the chronology of key events, such as the replacement of Neanderthals by modern humans in Europe. However, the method does not always provide precise and accurate enough ages to understand the important processes of human evolution. Here we review the newest method developments in radiocarbon dating (‘Radiocarbon 3.0’), which can lead us to much better chronologies and understanding of the major events in recent human evolution. As an example, we apply these new methods to discuss the dating of the important Palaeolithic site of Bacho Kiro (Bulgaria).

Navigating Interracial Borders
\"One of the best books written about interracial relationships to date. . . . Childs offers a sophisticated and insightful analysis of the social and ideological context of black-white interracial relationships.\"-Heather Dalmage, author Tripping on the Color Line
\"A pioneering project that thoroughly analyzes interracial marriage in contemporary America.\"-Eduardo Bonilla-Silva, author of Racism without Racists: Color-Blind Racism and the Persistence of Racial Inequality in the United States
Is love color-blind, or at least becoming increasingly so? Today's popular rhetoric and evidence of more interracial couples than ever might suggest that it is. But is it the idea of racially mixed relationships that we are growing to accept or is it the reality? What is the actual experience of individuals in these partnerships as they navigate their way through public spheres and intermingle in small, close-knit communities?
In Navigating Interracial Borders, Erica Chito Childs explores the social worlds of black-white interracial couples and examines the ways that collective attitudes shape private relationships. Drawing on personal accounts, in-depth interviews, focus group responses, and cultural analysis of media sources, she provides compelling evidence that sizable opposition still exists toward black-white unions. Disapproval is merely being expressed in more subtle, color-blind terms.
Childs reveals that frequently the same individuals who attest in surveys that they approve of interracial dating will also list various reasons why they and their families wouldn't, shouldn't, and couldn't marry someone of another race. Even college students, who are heralded as racially tolerant and open-minded, do not view interracial couples as acceptable when those partnerships move beyond the point of casual dating. Popular films, Internet images, and pornography also continue to reinforce the idea that sexual relations between blacks and whites are deviant.
Well-researched, candidly written, and enriched with personal narratives, Navigating Interracial Borders offers important new insights into the still fraught racial hierarchies of contemporary society in the United States.

Love and intimacy in online cross-cultural relationships : the power of imagination
\"This book challenges assumptions about the motivations that drive women from relatively poor, developing countries to use intermarriage dating sites to find partners from relatively wealthy, developed countries. It is generally assumed that economic deprivation or economic opportunities are the main factors, but this book instead focuses on the work of women's imagination in online cross-cultural relationships, including the role of desire, love and intimacy. The experiences of Thai women are used to explore how they initiate, develop and maintain love and intimacy with Western men across distance and time. The book shows that, in the absence of opportunities to search and meet partners from geographically distant parts of the world, the technology of the internet offers new ways of searching for and managing relationships and has significant consequences for local experiences and expectations of love and partnering. The book will be of interest to scholars and students with an interest in family and intimate life, gender and sexualities, Asian and Thai studies, globalization and nationalism, culture and media, sociology and anthropology.\"--Back cover.

The importance of shell: Redating of the To’aga site (Ofu Island, Manu'a) and a revised chronology for the Lapita to Polynesian Plainware transition in Tonga and Sāmoa
Radiocarbon dating Pacific archaeological sites is fraught with difficulties. Often situated in coastal beach ridges or sand dunes, these sites exhibit horizontal and vertical disturbances, datable materials such as wood charcoal are typically highly degraded, may be derived from old trees or driftwood unless specifically identified to short-lived material, while bone collagen rarely survives in tropical conditions. Shell, therefore, is the most logical material for dating Pacific sites since it is resistant to alteration, can be sampled to ensure only the last few seasons of growth are represented and is often closely tied to human economic activities. However, shell radiocarbon (14C) dating has been plagued by interpretive problems largely due to our limited knowledge of the 14C cycle in nearshore marine and estuarine environments. Consequently, shell dates are typically ignored in regional chronometric evaluations and in recent years shell is often avoided for dating altogether. Recent advances in our understanding of the source of shell 14C as well as the development of the first South Pacific Gyre model of changing marine 14C over time, combined with Bayesian statistical modelling, now provide us with insight into the value of these shell radiocarbon dates. Here we present a revision of the age of the To'aga site on Ofu Island-an early occupation site associated with the initial Polynesian Plainware period in Sāmoa, the earliest use of which we date to between 2785 and 2607 cal BP (68% probability).

39Ar dating of cave ice combined with pollen, cryogenic calcite and radiocarbon analyses reveals late Little Ice Age origin (Leupa Ice Cave, Julian Alps)
High-latitude or high-altitude caves often preserve ice deposits that contain valuable signals of past climate conditions, sometimes even reflecting regional and local atmospheric variability. Phases of aggradation or degradation of underground ice can also provide insights into the temporal evolution of Alpine permafrost. Such data are typically obtained from ice cores, which require a well-constrained chronological framework to be meaningful. In recent years, several dating methods have been developed or refined for glacier and ice sheet cores. However, some of these techniques have not yet been applied to cave ice. In this study, the 39Ar dating technique using Argon Trap Trace Analysis is applied for the first time to an underground ice deposit in the southeastern Alps, specifically in the Canin-Kanin massif (Julian Alps). The results are compared with pollen markers extracted from the ice, with U-Th dating of cryogenic cave carbonates found in situ within the same ice block, and with radiocarbon (14C) dating of the water-insoluble organic carbon fraction embedded in the ice. This integrated approach enabled dating the ice deposit to the end of the Little Ice Age, at the onset of the subsequent warming phase.

Radiocarbon dating of two old African baobabs from India
The article presents the radiocarbon investigation of the baobab of Jhunsi, Allahabad and the Parijaat tree at Kintoor, two old African baobabs from northern India. Several wood samples extracted from these baobabs were analysed by using AMS radiocarbon dating. The radiocarbon date of the oldest samples were 779 ± 41 BP for the baobab of Jhunsi and 793 ± 37 BP for the baobab of Kintoor. The corresponding calibrated ages are 770 ± 25 and 775 ± 25 calendar years. These values indicate that both trees are around 800 years old and become the oldest dated African baobabs outside Africa.
