What constitutes a ‘trip’? Examining child journey attributes using GPS and self-report

Active travel is associated with improved health and development outcomes in children. Accurate detection of children's travel behaviors and routes, however, is problematic. Travel diaries are often used to collect information on children's travel behaviors, yet no evidence for the accuracy of this methodology exists. This study investigated the validity of children's self-reported trips (origin, destination) compared with an objective criterion (global positioning systems units; GPS). Children (n = 10, 9–11 y) wore the GPS units for seven consecutive days between March and June 2011 and completed travel diaries daily with researcher assistance. Affinity group interviews were conducted in December 2011 with 30 children from two schools to garner perspectives on trip definition, neighborhood perceptions, and to illuminate GPS and travel diary findings. GPS journeys were manually compared with travel diary journeys for destination sequencing, start times, and travel mode. Accuracy in trip sequencing was compared by day type, and journey type using percentage differences and the chi-square (χ²) statistic. Of the 380 trips captured, 54.5% of journey sequences were fully or partially matched, 22.4% were GPS only trips and 23.2% travel diary only. Greater accuracy (full/partial match) was observed for weekdays than for weekend days and for the journey to or from school than for other journeys. Travel mode agreement existed for 99% of matched trips. Although children's travel diaries may confer contextual journey information, they may not provide completely accurate information on journey sequencing. Thematic analysis of affinity group data revealed that reasons for this are multifaceted, including differing concepts of what constitutes a ‘trip’. A combined approach of GPS and travel diary is recommended to gather a comprehensive understanding of children's journey characteristics.     

Introduction: Feminist Theories and Archaeology

This journal issue developed out of a desire to increase the use of feminist theory in archaeology, leading me to ask Laurajane Smith of York University to co-organize a symposium on the topic for the World Archaeological Congress in Dublin in July 2008. The impacts of major feminist theories on constructions of the past and archaeological thinking are discussed, emphasizing how they implicitly or explicitly influenced other articles in this journal issue.     

Tending and drive hunting: A density-mediated attrition model can explain age profiles of white-tailed deer at Iroquoian village sites

In a 1993 paper, Noble and Crerar suggested, based on the age and sex distribution of white-tailed deer (Odocoileus virginianus) longbones from four Attawandaron Iroquoian sites around the western end of Lake Ontario, that the contact-period Attawandaron were managing local deer populations, in response to the aboriginal trade in hides. Having observed similar patterns of differential preservation of elements and epiphyseal fusion at nearby Iroquoian sites that are not ascribed to the Attawandaron, and which pre-date the hypothesised trading period, we argue that these patterns may instead relate to bone density and/or vulnerability to taphonomic effects of late-fusing epiphyses. We further support our argument through age profiles based on dental eruption and wear.     

The Paradox of the Earned Income Tax Credit: Appreciating Benefits but not Their Source

The Earned Income Tax Credit (EITC) is widely recognized as the United States’ most effective contemporary policy for reducing poverty, and scholars have found that it elevates recipients’ sense of social inclusion. This raises the question of how it influences recipients’ civic engagement, namely their attitudes about government and political participation. We draw on policy feedback scholarship to consider expectations. Then we use a unique dataset to compare recipients of the EITC, Aid to Families With Dependent Children/Temporary Assistance to Needy Families, and nonrecipients of either policy in order to identify how policy features are related to political attitudes and behaviors. We find that despite the benefits they receive, EITC recipients experience low external political efficacy, but are more likely to be politically active than their peers.

Feminist Theorizing of Patriarchal Colonialism,Power Dynamics,and Social Agency Materialized in Colonial Institutions

In the twenty-first century historical archaeologists have increasingly drawn on post-colonial theory to analyze the European conquest and colonization of the Americas, Australasia, and Africa. However, few have employed feminist theories to gain insights into the patriarchal power dynamics that were fundamental to institutionalized colonial ideologies and practices. This paper provides feminist theorizing of new concepts and a heterarchical model of multiple interacting powers that increase understanding of complex gender and sexual power dynamics between colonizers and colonized.     

Stable isotope dietary analysis of prehistoric populations from the Minusinsk Basin,Southern Siberia,Russia: a new chronological framework for the introduction of millet to the eastern Eurasian steppe

We report the results of stable carbon and nitrogen isotope analysis of 354 human and faunal samples from five archaeological cultures of the Minusinsk Basin, Southern Siberia – Afanasyevo, Okunevo, Andronovo, Karasuk and Tagar (ca. 2700–1 BC) – a key location in Eurasia due to its position on a northern corridor linking China and central Eurasia. The results indicate that the diet of Eneolithic to Middle Bronze Age (Afanasyevo to Andronovo) populations was primarily C₃-based, with C₄ plants only becoming an important component of the diet in the Late Bronze Age Karasuk and Early Iron Age Tagar cultures. Freshwater fish seems to have been an important constituent of the diets in all groups. The findings constitute the earliest concrete evidence for the substantial use of millet in the eastern Eurasian steppe. We propose that it was probably introduced from Northwestern China during the Karasuk culture at the start of the Late Bronze Age, ca. 1500 BC. We conclude with a discussion of the implications for the nature of pastoralist economies on the steppes.     

Restructuring in the forest sector and the re‐shaping of women's work identities

This article explores how women forest workers’ perceptions of restructuring are related to their work identities. Drawing on semi‐structured interviews with 29 women working in subsidiaries of a multinational forest company in northern Saskatchewan, I describe how women workers selectively drew on traditional mill worker and flexible worker identities to legitimize and delegitimize restructuring. Women's understandings of themselves as workers were shaped by their paradoxical relationships to standard forest processing work. Some women with previous experience working in low‐waged service industries adopted worker subjectivities that legitimized restructuring and valued flexibility, individual empowerment, and mobility. Other women delegitimized restructuring, referencing traditional characterizations of forest work that valued community stability, collective resistance, and security. Many women, however, neither consistently legitimized nor delegitimized restructuring throughout their interviews. This last group's ambiguous portrayal of work and restructuring demonstrates the identity dilemmas faced by new entrants to declining industrial sectors. Restructuring interrupted women's narratives of having found a “good job” in forestry and prompted the renegotiation of their understandings of mill work. This article contributes to our understanding of restructuring in resource industries by drawing attention to how worker identities, gender, and industrial change are interrelated.     

“To Put into Complete Practice Those Hallowed Principles”: Edward Coles and the Crafting of Antislavery Nationalism in Early Nineteenth‐Century America

Edward Coles is famous for his decision to liberate his enslaved property and his political activities in Illinois during the 1820s. Few scholars, however, have recognized that this was merely the opening chapter in a life‐long struggle against slavery. His career in Illinois and his subsequent effort to promote emancipation in Virginia are arguably more significant because those struggles led him to construct an antislavery argument that united principle, prejudice, and the recognition of a shared antislavery past. Cast under the banner of antislavery nationalism, Coles’ approach to the problem of slavery was uniquely designed to appeal to Northerners and the Southerners alike.     

Caledogonia,a new smooth trigoniacean bivalve from the Triassic of New Caledonia

Caledogonia globosa gen. et sp. nov. is considered to be a member of the Myophoriidae following the classification of Newell & Boyd (1975). It is a more evolved genus than Agonisca Fleming from the Ladinian of New Zealand. Both are probably the descendants of Neoschizodus of the Andean-West Antarctic region, a dispersal route on the southern Gondwanaland coastline. Caledogonia was probably a rapid burrower in a high energy paleoenvironment. It occurs in a rhythmic sequence of greywackes and conglomeratic shell beds that lie on pre-Triassic basement. Like the associated bivalves, Maoritrigonia and Manticula, Caledogonia is an endemic genus of the Late Triassic Maorian Province.

Caledogonia globosa gen. et sp. nov. est a rapporter aux Myophoriidae, d'après la classification de Newell & Boyd (1975). Plus évolué que le genre Agonisca Fleming du Ladinien de Nouvelle Zélande, il descend probablement, comme celuici de Neoschizodus représenté dans la region Andine et West Antarctique, zone de dispersion faunique de la cote Sud des Terres de Gondwana. Caledogonia, était un fouisseur actif dans un paléoenvironnement de haute énergie et de sédimentation rapide. On le trouve aujourdhui dans une séquence rythmique de grauwackes alternant avec des lumachelles et conglomérats, transgressive sur le substratum antétriasique. Comme les bivalves associés Maoritrigonia et Manticula, Caledogonia est un genre endémique de la province máorie du Trias supérieur.
