What is a Burin? Typology,Technology, and Interregional Comparison

Classification of artifacts has long marked a significant edge between theory and practice in archaeology. While considering classification to be a necessary methodological device, most practitioners also recognize that it carries with it built-in assumptions. This essay approaches the issue by way of a specific stone tool type from Old World sites: the burin. By asking “what is a burin?” the study shows the need to reconsider typologies to reflect changes in research questions and progress in dating methods, especially when working with museum collections and secondary data between regions and across national traditions, and the need to study whole collections from the perspective of technological choices.     

Evolving ecosystems: ecological data from an Iron Age small mammal accumulation at Alorda Park (Catalonia,Spain)

Small mammals are considered to be good indicators of ancient environments. One particular layer in a fortification tower of a Mediterranean Iberian village, Alorda Park (4th century BC), provided a large amount of well-preserved small mammal bones (about 19,200 remains) probably accumulated by barn owls (Tyto alba). Such an accumulation is rarely available from the Iron Age. It provides not only palaeoenvironmental data, but also further information about other studies such as morphometrics, ancient DNA and zoogeography. This article focuses on the ecological data, and attempts to develop an accurate taphonomic study to assess the reliability and statistical significance of this archaeological sample.     

The Politics of Sources Meets the Practices of the Librarian: An Interview with Esther Chen**

[I] want to single out one phenomenon that could be called the ‘politics of sources’. It points to the extent to which the histories that both scientists and historians can write are artifacts of the available sources. The Rockefeller Foundation not only opened its archives very early on for historical work but also invested a lot in making the archives readily available for historical exploration. During the 1980s, many young historians took advantage of this opportunity. Thus, in a relatively early phase of the professional historiography of molecular biology, one could have gained the impression that the development of the new biology as a whole was a bio-politically directed enterprise of the Rockefeller Foundation sustained by the vision that social processes could ultimately be controlled by biological processes.     

Human guinea pigs? The history of the early oral contraceptive clinical trials

Abstract

Today it is estimated that over 100 million women worldwide have taken oral contraceptives since their first clinical trials in 1956. Despite their popularity, however, contraceptive pills have been under constant scrutiny for their safety since the time of their marketing. This paper considers the degree to which the pill was tested before it was introduced on to the market and challenges many assumptions that have been made about the use scientists made of women in its development. Examining the early testing of the pill, the paper makes clear that the success of the pill and its testing depended on the active co‐operation of the women who swallowed the tablet in its experimental stage. Far from being guinea‐pigs, women were thus active participants in the making of the pill.     

First records of Geinitziidae (Insecta: Grylloblattida) from the Upper Triassic of Argentina (Mendoza)

Lara, M.B. & Aristov, D., August 2016. First records of Geinitziidae (Insecta: Grylloblattida) from the Upper Triassic of Argentina (Mendoza). Alcheringa 41, xxx–xxx. ISSN 0311-5518

A new grylloblattid (Permoshurabia argentina sp. nov.: Geinitziidae) is described and illustrated from the Upper Triassic of Argentina. The material represents the first record of this family from Argentina and expands the geographic distribution of this group during the Triassic.

The just city for whom? Re-conceiving active citizenship for lone mothers in Canada

In this article we argue that the ‘just city’ is one that enables individuals to exercise their citizenship, including making choices to participate (or not) in communal existence. However, inequities in resource distribution encountered by lone mothers on income assistance threaten not only individual sustenance and survival, but also the foundational fabric of our society. The implication that an active citizen is one who exercises their rights and responsibilities in a balanced way is problematic, and has the potential to add blame to poverty, justifying exclusion rather than inclusion. Using qualitative data from a longitudinal study of lone mothers in extreme poverty in Vancouver, British Columbia we illustrate how macro-processes within cities (i.e., delivery of affordable housing, food security, childcare, transportation) impinge upon the micro-processes of these women's lives (i.e., impacts on health, economic security, social mobility). Focusing on citizenship as a set of constrained choices challenges the policies and practices of social planning to consider how the scope of citizenship can be expanded by shaping key urban opportunities. Grounding the vision of a just city in the potential for personal agency suggests that policymakers and planners have a key role in shaping citizenship for the most marginalized and oppressed through a combination of providing supports and enabling opportunities in the urban environment.     

A Cross-Cultural Study of Young Children's Mapping Abilities

The mapping abilities of four-year-old children in York, England, Durban, South Africa, Tehran, Iran, Mexico City, Mexico and Evanston, Illinois, USA were investigated, using a methodology involving air-photo identification and simulated navigation on an air photo. The results show that essential mapping abilities (perspective and scale transformations) are well developed by the age of four in these cultures, and provide some evidence in support of the hypothesis that mapping abilities emerge without training in very young children of all cultures.
