What's Next?: The Future of Progressivism as an "Infinite Succession of Presents"
Progressive education, though its meaning be contested, is the basic idea that schools should be agents of democracy. To reform society, we must reform the schools. The converse is also true: Change in schooling is realizable only to the extent that society progresses. Thus, progressive education entails not merely progressive methods for individual learners, but education for a progressive society. Howard Zinn‘s words, which could easily be pinned to progressive ideals, provide a meaningful framework for reading these contributions: "The future is an infinite succession of presents, and to live now as we think humans should live, in defiance of all that is bad around us, is itself a marvelous victory‖ (2004, para. 11). In their own way, and from far-flung diverse places such as Spain, Indonesia, China, the UK, and the US, each piece is simultaneously a story about the past, present and future. Each one is a link in this chain of "infinite successions.published or submitted for publicationis peer reviewe

Toward understanding of differences in current cloud retrievals of ARM ground-based measurements
Accurate observations of cloud microphysical properties are needed for evaluating
and improving the representation of cloud processes in climate models and better estimate
of the Earth radiative budget. However, large differences are found in current cloud
products retrieved from ground-based remote sensing measurements using various retrieval
algorithms. Understanding the differences is an important step to address uncertainties
in the cloud retrievals. In this study, an in-depth analysis of nine existing ground-based
cloud retrievals using ARM remote sensing measurements is carried out. We place
emphasis on boundary layer overcast clouds and high level ice clouds, which are the focus
of many current retrieval development efforts due to their radiative importance and
relatively simple structure. Large systematic discrepancies in cloud microphysical
properties are found in these two types of clouds among the nine cloud retrieval products,
particularly for the cloud liquid and ice particle effective radius. Note that the differences
among some retrieval products are even larger than the prescribed uncertainties reported by
the retrieval algorithm developers. It is shown that most of these large differences have
their roots in the retrieval theoretical bases, assumptions, as well as input and constraint
parameters. This study suggests the need to further validate current retrieval theories and
assumptions and even the development of new retrieval algorithms with more observations
under different cloud regimes
Consensus guidelines for the use and interpretation of angiogenesis assays
The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitations. This article describes in vivo, ex vivo, and in vitro bioassays that are available for the evaluation of angiogenesis and highlights critical aspects that are relevant for their execution and proper interpretation. As such, this collaborative work is the first edition of consensus guidelines on angiogenesis bioassays to serve for current and future reference
The Disappearance of Technology: Toward an Ecological Model of Literacy
We tend to think of technology as a set of tools to perform a specific function. These tools are often portrayed as mechanistic, exterior, autonomous, and concrete devices that accomplish tasks and create products. We do not generally think of them as intimately entwined with social and biological lives. But literacy technologies, such as pen and paper, index cards, computer databases, word processors, networks, e-mail, and hypertext, are also ideological tools; they are designed, accessed, interpreted, and used to further purposes that embody social values. More than mechanistic, they are organic, because they merge with our social, physical, and psychological beings. Thus, we need to look more closely at how technologies are realized in given settings. We may find that technological tools can be so embedded in the living process that their status as technologies disappears.published or submitted for publicationis peer reviewe
Teaching Indigenous methodology and an Iñupiaq example
In any graduate research methods course, one must teach the underlying assumptions of various research paradigms, and the interrelated philosophical principles of epistemology, ontology and axiology. At an Alaskan university, many people do research and work with Alaska Native communities, so a grasp of an Alaska Native epistemology is crucial. This paper explores how and why Author One, Maureen Hogan, teaches epistemology (in general) and Indigenous epistemology (in particular) in her graduate field-based research methods course. Second, she reflects upon why she may or may not be successful in this task. Throughout the article, Sean Topkok, Author Two, a recent doctoral student, shares how he developed his own Iñupiaq research method, Katimarugut, in the class. To date, an Alaska Native research methodology does not exist. Together, we hope to add one useful model for decolonizing the academy
