Variation in strontium isotope ratios of archaeological fauna in the Midwestern United States: a preliminary study

Strontium isotope values (⁸⁷Sr/⁸⁶Sr) in bone and tooth enamel have been used increasingly to identify non-local individuals within prehistoric human populations worldwide. Archaeological research in the Midwestern United States has increasingly highlighted the role of population movement in affecting interregional cultural change. However, the comparatively low level of geologic variation in the Midwestern United States might suggest a corresponding low level of strontium variation, and calls into question the sensitivity of strontium isotopes to identify non-local individuals in this region. Using strontium isotopes of archaeological fauna, we explore the degree of variability in strontium ratios across this region. Our results demonstrate measurable variation in strontium ratios and indicate the potential of strontium analysis for addressing questions of origin and population movement in the Midwestern United States.     

Advocacy coalitions,beliefs, and learning: An analysis of stability,change, and reinforcement

Policy processes are ongoing phenomena without beginning or end. Accordingly, a major focus of research has been on questions of stability and change. This paper continues in this tradition by examining advocacy coalition stability, belief change, and learning. This paper draws on three waves of policy actor surveys that compare panel and non-panel samples. The data were collected in 2013, 2015, and 2017 in the context of oil and gas development in Colorado, USA. The findings mostly confirm that coalitions and beliefs tend to be stable and that learning leans toward reinforcement rather than change in beliefs. However, although rare, some instances of belief change, change in coalition membership, and changing policy positions occur. This paper makes theoretical and empirical contributions to the study of stability, change, and reinforcement of advocacy coalitions and their beliefs and charges policy scholars to look more at the exceptions to the evidence rather than the confirmations.     

Drivers of (in)equity in collaborative environmental governance

Collaborative environmental governance seeks to engage diverse stakeholders to tackle complex challenges efficiently, sustainably, and equitably. However, mixed empirical evidence underscores a need to understand the conditions under which particularly equity is or is not achieved. Here, we use the empirical case of California Sustainable Groundwater Management to quantify the extent to which vulnerable small and rural drinking water users' needs are addressed in collaborative groundwater planning. Drawing on a diverse array of mixed method data, we then employ Boosted Regression and Classification Trees (BRCT) to assess potential driving factors including collaboration, representation, elite capture, stakeholder engagement, and problem severity/salience. We find each to be influential, highlighting their relevance for equitable planning. We also find evidence that these relationships are complex and outcome specific. Nonetheless, the overall effect on the three equity measures is modest at best. More institutional analysis of collaborative governance regimes from diverse contexts is needed to build a comprehensive understanding of how to meaningfully advance social and environmental equity in such decentralized reforms. Based on our results, we suggest the answer, if there is one, may transcend current focal domains such as stakeholder representation and engagement.     

Immigrants riding for justice: Space-time and emotions in the construction of a counterpublic

During the past two decades, a new immigrants’ rights movement in the U.S. has emerged, constructing a counterpublic that challenges hegemonic immigration discourses, policies, and practices. We show how a counterpublic is constructed in practice, using as a case study the Immigrant Workers’ Freedom Ride (IWFR), an event in 2003 that helped further the momentum of immigrant rights activism. We examine how immigrant activists and their allies came together and worked to construct, articulate, and enact a shared political identity that we refer to as an identity-in-alliance. Space-time and emotions were crucial in the development of this identity as ‘Freedom Riders,’ as well as a sense of solidarity. We reflect on the vulnerabilities within the counterpublic and challenges it faced when inserting its discourses on immigration, race, and citizenship into the hegemonic public sphere. Taking the insights gained from these practices, we extend Nancy Fraser’s concept of the counterpublic by demonstrating the centrality of space-time and emotions to its theorization.     

Do Ships Shape the Shore? An Analysis of the Credibility of Ship Archaeological Evidence for Landing Site Morphology in the Baltic Sea

In the context of the development of different kinds of watercraft during prehistory an interdependent line of development for landing sites and harbours is often suggested, and used to argue that it is almost impossible archaeologically to locate small and early landing sites. Although the constructional properties of prehistoric watercraft suggest that landing‐structures were not absolutely necessary, there is nevertheless archaeological evidence of landing‐facilities from the Stone Age, as well as landing‐facilities for smaller boats to consider. This article will discuss to what extent ship archaeological evidence could be seen in a corresponding development to landing sites in its respective periods. © 2012 The Author     

Domestic economies and regional transition: Household multicrafting and lake exploitation in pre-Aztec Central Mexico

This article takes a micro-archaeology approach to investigating household production strategies using data derived from Early to Middle Postclassic (A.D. 900–1350) houses from Xaltocan, Mexico, an island capital in the northern Basin of Mexico. I examine household production strategies by integrating multiple lines of evidence including microartifacts, soil chemistry, and macroartifact remains to document a diversity of household production activities, including the manufacture of goods that are typically invisible archaeologically such as foods and perishable goods. Next, I consider changes in subsistence practices through time in order to understand household scheduling and labor allocation strategies. The results indicate that households in pre-Aztec Xaltocan not only pursued diverse economic strategies, but also engaged in multiple types of production activities, including the manufacture of food products and other utilitarian goods derived from lake resources. I conclude that households were fundamental to economic development in ancient political economies and were enmeshed in broader systems of power and networks of exchange.     

Experts in Their Own Lives: Emphasizing Client-Centeredness in a Homeless Program

This paper presents a case study of a homeless organization in Burlington, Vermont that is dedicated to the principles of client-centeredness. Originated by psychologist Carl Rogers as a therapeutic philosophy, this approach has been applied in numerous social service and organizational settings. For this Vermont agency, client-centered practice entails the promotion of client empowerment and the responsible use of staff authority. Client participation in homeless programming is identified as one tool that may facilitate both client autonomy and a balance of staff-client power. Clients, staff, and administrators of this agency were interviewed to help explain the philosophy and practice of client-centeredness, as well as pitfalls of the client-centered approach. Hypotheses and future questions for research are also suggested.
