Introduction: The ethical constitution of energy dilemmas

Growing anthropological research on energy provides critical explorations into the cross-cultural ways in which people perceive and use this fundamental resource. We argue that two dominant frameworks animate that literature: a critique of corporate and state power, and advocacy for energy transitions to less carbon-intensive futures. These frameworks have narrowed the ethical questions and perspectives that the discipline has considered in relation to energy. This is because they are animated by judgements that can implicitly shape research agendas or sometimes result in strong accusations that obscure how our interlocutors themselves may consider the rightness and wrongness of energy resources and the societal infrastructures of which they form a part. We propose a more capacious approach to studying energy ethics that opens up energy dilemmas to ethnographic inquiry. As such, we show how energy dilemmas constitute important sites for the generation of anthropological knowledge, encouraging more insightful and inclusive discussions of the place of energy in human and more-than-human lives.     

From Mexico to Michigan and back: An international collaboration investigating primate behavior,ecology, and evolution from multiple perspectives

Evolutionary research benefits form the integration of laboratory and field components to determine factors and processes that affect the evolutionary trajectories of species. Our shared interest in understanding hybridization with genetic admixture as a process that may impact social, behavioral, and ecological features of primates, brought us together in a collaborative project aimed at addressing how vocal variation in two species of howler monkeys in Mexico affects and is affected by hybridization. To achieve this goal, we joined our academic expertise in studying primate genetics, ecology, and behavior under different natural and experimental conditions. We took advantage of decades of experience studying and handing wild howler monkeys for translocation projects to safely sample and study wild populations for this project. Here, we describe the history of our collaboration highlighting how our different perspectives, academic realities, and individual strengths built the foundation for our successful collaboration. We also share our perspectives on how this collaboration opened up new academic venues, broadened our individual perspectives on the integration of different research approaches to address a complex topic, and allowed us to recognize the strength of international collaboration.     

A novel computational approach "BP-STOCH" to study ligand binding to finite lattice

We report a novel computational algorithm "BP-STOCH" to be used for studying single-type ligand binding with biopolymers of finite lengths, such as DNA oligonucleotides or oligopeptides. It is based on an idea to represent any type of ligand-biopolymer complex in a form of binary number, where "0" and "1" bits stand for vacant and engaged monomers of the biopolymer, respectively. Cycling over all binary numbers from the lowest 0 up to the highest 2(N) - 1 means a sequential generating of all possible configurations of vacant/engaged monomers, which, after proper filtering, results in a full set of possible types of complexes in solution between the ligand and the N-site lattice. The principal advantage of BP-STOCH algorithm is the possibility to incorporate into this cycle any conditions on computation of the concentrations and observed experimental parameters of the complexes in solution, and programmatic access to each monomer of the biopolymer within each binding site of every binding configuration. The latter is equivalent to unlimited extension of the basic reaction scheme and allows to use BP-STOCH algorithm as an alternative to conventional computational approaches.     

中国履行生物多样性公约的成就和展望

2004年是生物多样性公约实施10周年。中国于1993年1月7日作为第7个国家正式加入“公约”。接着就由国家环境保护总局牵头组建国家履约协调组和许多联络点,下设办公室负责日常工作。可见,国家对生物多样性工作的重视和认真的态度。10年来,中国在履约方面做了大量工作,成绩显著。例如,完成了“中国生物多样性国情研究报告”和“中国生物多样性保护行动计划”等一大批重要文件,建立了“生物多样性委员会”、“生物多样性保护基金会”和相应的科学与教育部门,开展了许多科研项目和讲授相关的课程,出版了系列丛书和“中国生物多样性”学术刊物,重视开展学术交流,建立了生物多样性数据库和相关的管理政策,生物多样性保护实体和产业日益增加和发展等就是明显的事例。履约10年的经验在于下列三个方面(1)保护和发展必须密切结合;(2)“统一协调、分散管理”的方针需要进一步完善;(3)基础性和综合性研究需要加强。展望未来,只有在加强基础和综合研究以及提高管理水平方面下一番功夫,履约工作才能取得更大的成绩。     

A "how to" guide for developing a publishable Scholarship of Teaching project

In order for the efforts of scholarly teaching to be recognized, the work must become public and presented to peers for review. Scholarship of Teaching is not only improving instruction and learning but also methodically assessing whether specific teaching interventions have had the desired effect. In this paper, the author presents a step-by-step guide for how to develop a Scholarship of Teaching project that is well thought out and worthy of publication. Factors to consider before performing such pedagogical research include developing a clear research hypothesis for the classroom, reviewing the background literature, obtaining Institutional Review Board (Human Subjects) approval, and determining which methods of assessment may be used. This "how to" guide discusses how to handle all of these factors and prepare the data for publication and introduces the reader to references related to the Scholarship of Teaching and learning as well as educational research and theory.     

<Emphasis Type="Italic">Phragmites</Emphasis><Emphasis Type="Italic">australis</Emphasis> as a model organism for studying plant invasions

The cosmopolitan reed grass Phragmites australis (Poaceae) is an intensively studied species globally with a substantial focus in the last two decades on its invasive populations. Here we argue that P. australis meets the criteria to serve as a model organism for studying plant invasions. First, as a dominant species in globally important wetland habitats, it has generated significant pre-existing research, demonstrating a high potential for funding. Second, this plant is easy to grow and use in experiments. Third, it grows abundantly in a wide range of ecological systems and plant communities, allowing a broad range of research questions to be addressed. We formalize the designation of P. australis as a model organism for plant invasions in order to encourage and standardize collaborative research on multiple spatial scales that will help to integrate studies on the ecology and evolution of P. australis invasive populations, their response to global environmental change, and implications for biological security. Such an integrative framework can serve as guidance for studying invasive plant species at the population level and global spatial scale.     

Resituating the Place of Educational Discourse in Anthropology

This critical essay examines the place of educational discourse in contemporary anthropology. I address the growing influence of "cultural studies" frameworks in anthropology—especially in research on popular culture, media, and identity—and the corresponding neglect of specifically educational discourses and practices, in and out of schools. To illustrate, I briefly examine recent research by four noted cultural anthropologists who mention the effects of schools at their field sites but pay insufficient attention to complex educational discourses and practices. Then I address the reasons why most contemporary anthropologists outside the subfield of "anthropology of education" ignore or downplay the role of modern schools in structuring identities and power relations, both locally and globally. I end with a programmatic synthesis: to recognize and account for the continuing power of schools in most contemporary ethnographic sites, even as we broaden our vision of "education" and extend our analytic tools well beyond schools. This resituating of educational discourse in anthropology might accomplish two important things. First, it could arrest the trend toward subfield specialization and provide a more unifying research program. Second, it would promote anthropology's renewed engagement with some of the most pressing problems of democracy and public policy, fostering an organic link between our multiple roles as teachers, researchers, and institutional actors, [education, identity, cultural studies, ethnographyJ     

Introducing "Frontiers in Zoology"

As a biological discipline, zoology has one of the longest histories. Today it occasionally appears as though, due to the rapid expansion of life sciences, zoology has been replaced by more or less independent sub-disciplines amongst which exchange is often sparse. However, the recent advance of molecular methodology into "classical" fields of biology, and the development of theories that can explain phenomena on different levels of organisation, has led to a re-integration of zoological disciplines promoting a broader than usual approach to zoological questions. Zoology has re-emerged as an integrative discipline encompassing the most diverse aspects of animal life, from the level of the gene to the level of the ecosystem.The new journal Frontiers in Zoology is the first Open Access journal focussing on zoology as a whole. It aims to represent and re-unite the various disciplines that look at animal life from different perspectives and at providing the basis for a comprehensive understanding of zoological phenomena on all levels of analysis. Frontiers in Zoology provides a unique opportunity to publish high quality research and reviews on zoological issues that will be internationally accessible to any reader at no cost.     

"Decisions and Dispositions": Socializing Spatial Archaeology

Concerns with spatial dimensions and social inference have long histories in archaeology. However, the two histories are not always conjoined. This article considers changing understandings of space in archaeology in the last half century, and the variable nature of what "social" has denoted and connoted during that same span. The review highlights recurring calls for a social archaeology, and the degree to which, in such instances, social inference has been expressed in spatial terms, especially as these have recognized people's "decisions and dispositions" as shaping the archaeological record. Life histories of place receive special attention as ways of discerning the existence and social impact of such decisions and dispositions. These life histories constitute an arena in which archaeologists from diverse theoretical perspectives can offer complementary insights. Moreover, they exemplify ways in which social and spatial inferences in archaeology contribute to wider understanding of human experience.

THE POWER OF THE " A" -" NOT A" METHOD

The " A" - " Not A" method is a rating method with two categories. It is often treated as a discrimination method. Unlike forced choice procedures, the Thurstonian model for this method involves a choice criterion. In statistical tests, it is treated as a comparison of two proportions. In this paper, the power for hypothesis tests involving the monadic and replicated monadic " A" - " Not A" method is discussed. The power functions and the sample sizes needed for 80% power are given based on Thurstone's δ. Designs with equal and unequal allocations for A and A (Not A) samples are considered. The power of the method is also compared with that of four forced choice methods under the assumption that the perceptual variance is identical among methods. The comparison shows that, in general, the power for the five methods ranks from high to low: the 3-AFC, 2-AFC, " A" - " Not A", triangular and duo-trio. The comparison also shows that, based on the same number of panelists and/or the same sample size for the A and A⁻ samples for the methods, if the panelists are not too discrepant and the choice criterion in the " A" - " Not A" method is not too strict or too lax, the power of the " A" - " Not A" method is very close to that of the 2-AFC method.     

The "Old West" in the Middle East: U.S. Military Metaphors in Real and Imagined Indian Country

ABSTRACT  In this article, I examine the role of the "Indian Country" heritage metaphor in U.S. military activities in the Middle East from a critical anthropological perspective. Research has revealed the proliferation of such discourse among soldiers, military strategists, reporters, and World Wide Web users to refer to hostile, unsecured, and dangerous territory in Iraq and Afghanistan. The salience of this symbol in 21st-century U.S. armed conflicts attests to its staying power in national narratives of colonialism at home and abroad. Summoning the "Indian wars" of the 19th century in the U.S. West as malleable symbolic parallels to the current war in Iraq serves to offer combat lessons in guerilla warfare while reinscribing epic stories of U.S. military imperialism and renarrating uncritically the struggles and conflicts of Native Americans, past and present, through the lens of contemporary perspectives on terrorism.     

DNA "fingerprints" and segregation analysis of multiple markers in human pedigrees

Tandem-repetitive DNA hybridization probes based on a putative human recombination signal detect multiple polymorphic minisatellite fragments in human DNA. The genetic complexity of the resulting individual-specific DNA "fingerprints" was investigated by studying a large sibship affected by neurofibromatosis and a more extensive pedigree segregating for two different hemoglobinopathies. The segregation of up to 41 different heterozygous DNA fragments from each parent could be analyzed in a single sibship, using two different repeat probes. Most of these variable DNA fragments could not be paired as alleles, to an extent which suggests that the DNA fingerprints are together derived from approximately 60 heterozygous loci (approximately 120 variable fragments), only a proportion of which can be scored in a given individual. Two or three of the DNA fragments detected by one probe showed tight linkage and may be derived from long minisatellite(s) that are cleaved to produce more than one polymorphic DNA fragment. Excluding allelic and linked DNA fragments, almost all remaining scorable fragments segregated independently, allowing up to 34 unlinked loci to be examined simultaneously. These loci are scattered over most or all of the human autosomes. Minisatellite probes are therefore suitable for rapid marker generation and can be applied to linkage analysis in human pedigrees.

Exploring the importance of institutional contexts for the development of ethnic stereotypes: a comparison of schools in Belgium and England

This article suggests the usefulness of an ecological approach in studying the development of teachers' ethnic stereotypes in schools. It builds on existing research in this area by exploring the importance of nationally specific educational contexts and school characteristics on the development of teachers' stereotypes of Turkish minority students. Observation and interview data from case-study research involving one Flemish (Belgian) and one English secondary, multicultural inner-city school suggest differences between Flemish and English teachers' ethnic stereotypes. These differences can in part be explained by the influence of nationally specific regulations governing teachers' power to evaluate students, a nationally specific policy on ethnic minority cultures and needs, the ethnic and gender composition of the school's student and staff population, and the enforcement of an inclusive school policy by the school's senior management. The conclusions discuss implications for further research on ethnic stereotyping and discrimination in schools.     

Teaching "Species"

A clear understanding of the term "species" is fundamental to the subject of evolution. However, introductory textbooks often fail to address this topic until one of the later chapters, after having used the term species in all preceding chapters. Furthermore, definitions of terms critical to a clear understanding of this subject are often vague or absent in chapters on species concepts. We feel the popular notion of a "species problem" has been unnecessarily inflated by this less-than-effective educational approach. Clearly addressing this essential subject at the beginning of a course on evolution will prepare students to learn the details and complexities of evolution. Here we provide the background for an alternative approach to this foundational topic, followed by an outlined lesson plan. We emphasize early introduction of this subject in texts and courses using unambiguous terminology and including the historical development of species concepts.     

An Efficient Gait-generating Method for Electrical Quadruped Robot Based on Humanoid Power Planning Approach

The research field of legged robots has always relied on the bionic robotic research,especially in locomotion regulating approaches,such as foot trajectory planning,body stability regulating and energy efficiency prompting.Minimizing energy consumption and keeping the stability of body are considered as two main characteristics of human walking.This work devotes to develop an energy-efficient gait control method for electrical quadruped robots with the inspiration of human walking pattern.Based on the mechanical power distribution trend,an efficient humanoid power redistribution approach is established for the electrical quadruped robot.Through studying the walking behavior acted by mankind,such as the foot trajectory and change of mechanical power,we believe that the proposed controller which includes the bionic foot movement trajectory and humanoid power redistribution method can be implemented on the electrical quadruped robot prototype.The stability and energy efficiency of the proposed controller are tested by the simulation and the single-leg prototype experi-ment.The results verify that the humanoid power planning approach can improve the energy efficiency of the electrical quadruped robots.     

Introduction to "Landscapes over Time"

There is a growing recognition that modern environmental problems bear striking resemblance to those faced by past societies and that to understand the environmental present we must consider the total sweep of anthropogenic environmental change on specific landscapes. This "In Focus" assembles five articles encompassing diverse time periods and different global regions to make the case that long-term perspectives on the relationship between people and their environmental contexts are critical for understanding and evaluating contemporary environmental debates, interpretations, and even policies.     

Education and the "new" inequality in Papua New Guinea

Literature has been produced over the last fifteen years in Papua New Guinea (PNG) concerned with the increasing level of socioeconomic differentiation which has accompanied political independence. Consensus exists that postcolonial PNG is experiencing increasing disparities in education, wealth, political power, and the general set of benefits typically associated with development and modernization. This author argues that studies of such growing socioeconomic stratification in the country have ignored or dismissed gender as a source of inequality. She focuses upon educational opportunity as the key to wealth and political power and shows that the most educationally disadvantaged group in PNG is rural women. Data to support her thesis are drawn from national censuses, the author's field work in the area of Madang Province, and literature on stratification. The national census includes data from both lowland and highland populations. Since the authors' field site is culturally and ecologically highland, however, the paper focuses upon the highlands, using data from nonhighland areas primarily for comparative purposes.     

Beyond "the State" and Failed Schemes

In this article, I propose five ways to move beyond the analytical scheme of James Scott's Seeing Like a State (1998). I question the spatial optic that posits an "up there," all-seeing state operating as a preformed repository of power, spread progressively outward to "nonstate" spaces beyond its reach. I highlight the role of parties beyond "the state" that attempt to govern—social reformers, scientists, and the so-called nongovernmental agencies, among others. I look beyond authoritarian high modernism to the more general problematic of "improvement" emerging from a governmental rationality focused on the welfare of populations. I explore the recourse to mētis (contextualized, local knowledge and practice) situated beyond the purview of planning. Finally, I reframe the question posed by Scott—why have certain schemes designed to improve the human condition failed?—to examine the question posed so provocatively by James Ferguson: What do these schemes do? What are their messy, contradictory, conjunctural effects?     

A microbial fuel cell capable of converting glucose to electricity at high rate and efficiency

A microbial fuel cell containing a mixed bacterial culture utilizing glucose as carbon source was enriched to investigate power output in relation to glucose dosage. Electron recovery in terms of electricity up to 89% occurred for glucose feeding rates in the range 0.5–3 g l^–1 d^–1, at powers up to 3.6 W m^–2 of electrode surface, a five fold higher power output than reported thus far. This research indicates that microbial electricity generation offers perspectives for optimization.
