Fishborne Trematode Metacercariae in Luang Prabang,Khammouane, and Saravane Province,Lao PDR

Fishborne trematode (FBT) metacercariae were investigated in fish from 3 Provinces of Lao PDR. Total 242 freshwater fish of 40 species were collected in local markets of Luang Prabang (59 fish of 16 species), Khammouane (81 fish of 19 species), and Saravane (97 fish of 14 species), and each of them was examined by artificial digestion method. Four species of metacercariae (Opisthorchis viverrini, Haplorchis taichui, Haplorchis yokogawai, and Centrocestus formosanus) were detected. O. viverrini was detected in 35 fish (14.5%), and their density was 252 per infected fish (Luang Prabang, 88 metacercariae in 5 fish; Khammouane, 187 in 6 fish; Saravane, 303 in 24 fish). H. taichui was found in 102 fish (42.1%), and their density was 485 per infected fish (Luang Prabang, 260 metacercariae in 38 fish; Khammouane, 1,084 in 23 fish; Saravane, 359 in 41 fish). H. yokogawai was detected in 92 fish (38.0%), and their density was 222 per infected fish (Luang Prabang, 362 metacercariae in 17 fish; Khammouane, 126 in 20 fish; Saravane, 214 in 55 fish). Metacercariae of C. formosanus were found in 8 fish (3.3%), and their density was 3 per infected fish. In the present study, it has been confirmed that FBT metacercariae, in particular, H. taichui, H. yokogawai, and O. viverrini, are highly prevalent in fish from Luang Prabang, Khammouane, and Saravane Province, Lao PDR.

Current Status of Human Taeniasis in Lao People's Democratic Republic

Human taeniasis was investigated in Lao People''s Democratic Republic (Lao PDR) between 2000 and 2011 as part of the nation''s helminthiasis survey. A total of 55,038 inhabitants, including 29,846 school children, were examined using the Kato-Katz and scotch-tape anal swab method, and morphological observation of adult worms. Molecular identification of Taenia tapeworms was performed by multiplex PCR or DNA sequence analysis of the mitochondrial cox1 gene. Taenia eggs were present at a rate of 1.5% (845/55,038) in the subject population. Adult tapeworms were identified as T. solium or T. saginata by analyzing the collectable stool specimens (n=126). Three specimens identified as T. solium were found in Luang Prabang, while the remaining 123 specimens, which were T. saginata, were found in Bokeo, Bolikhamxay, Champasak, Houaphan, Khammouane, Luang Namta, Luang Prabang, Oudomxay, Phongsaly, Saysomboune, Saravane, Savannakhet, Xayaboury, Xekong, Xieng Khouang Province, and Vientiane Municipality.     

Equine Gatekeepers,Animal Narratives and Foxhunting Landscapes

Firstly, this paper analyzes the dynamic between horse, rider, and landscape in foxhunting culture. Secondly, it considers nonhuman animals as active elements within the research process. The methodology principally involved extensive, in-depth participation as a rider within mounted foxhound packs, as I originally participated as a rider/ethnographer in order to understand the nexus between foxhunting culture and the landscape. However, the equine focus in my research emerged unexpectedly as my fieldwork drew me into a collaboration with an unanticipated character in this network; the “made hunter,” a horse seasoned for hunting. These animals acted as my equine gatekeepers literally incorporating me into this hunting world. I relied on and respected their experience and capabilities as novice and experienced foxhunters have done for centuries. This paper presents an analysis of the quadripartite synthesis of foxhunting culture, rider, horse, and landscape and involves a corporeal and sensory exploration of the human/nonhuman inter-Hunt dynamic that defines foxhunting. Hunting cultures rely upon the capabilities of animals and have developed an ability to translate animal narratives and semiotics. Thus, they provide us with a platform for developing the multi-species perspective in social science. This paper calls for an ethnographic approach which draws upon these epistemic systems and incorporates the superhuman abilities of animals into our understanding of our relationship with space. Animals, I argue, offer more than potential subjects to study. By incorporating their knowledge, experiences, and perspectives, and by translating their engagements with the world, we have the potential to augment our perception of our shared environment.

END‐OF‐LIFE CARE IN THE 21st CENTURY: ADVANCE DIRECTIVES IN UNIVERSAL RIGHTS DISCOURSE

This article explores universal normative bases that could help to shape a workable legal construct that would facilitate a global use of advance directives. Although I believe that advance directives are of universal character, my primary aim in approaching this issue is to remain realistic. I will make three claims. First, I will argue that the principles of autonomy, dignity and informed consent, embodied in the Oviedo Convention and the UNESCO Declaration on Bioethics and Human Rights, could arguably be regarded as universal bases for the global use of advance directives. Second, I will demonstrate that, despite the apparent consensus of ethical authorities in support of their global use, it is unlikely, for the time being, that such consensus could lead to unqualified legal recognition of advance directives, because of different understandings of the nature of the international rules, meanings of autonomy and dignity which are context‐specific and culture‐specific, and existing imperfections that make advance directives either unworkable or hardly applicable in practice. The third claim suggests that the fact that the concept of the advance directive is not universally shared does not mean that it should not become so, but never as the only option in managing incompetent patients. A way to proceed is to prioritize work on developing higher standards in managing incompetent patients and on progressing towards the realization of universal human rights in the sphere of bioethics, by advocating a universal, legally binding international convention that would outlaw human rights violations in end‐of‐life decision‐making.     

Public Memory and the Search for Power in American Historical Archaeology

How Americans remember the past is often reinforced by landscapes, monuments, commemorative ceremonies, and archaeology. These features and activities often help to create an official public memory that becomes part of a group's heritage. I suggest that public memory can be established by (1) forgetting about or excluding an alternative past, (2) creating and reinforcing patriotism, and/or (3) developing a sense of nostalgia to legitimize a particular heritage. These categories are not mutually exclusive, and the lines that separate these categories may not always be well defined. I show how post–Civil War American landscapes, monuments, and commemorative activities helped to reinforce racist attitudes in the United States that became part of the official memory. African Americans have struggled to revise the official memory of the Civil War, although the power to change this memory has been situational and not always successful, [commemoration, memory, material culture, historical archaeology, landscapes]     

Social Responsibility and the State's Duty to provide Healthcare: An Islamic Ethico‐Legal Perspective

The United Nations Educational, Scientific and Cultural Organization's (UNESCO) Declaration on Bioethics and Human Rights asserts that governments are morally obliged to promote health and to provide access to quality healthcare, essential medicines and adequate nutrition and water to all members of society. According to UNESCO, this obligation is grounded in a moral commitment to promoting fundamental human rights and emerges from the principle of social responsibility. Yet in an era of ethical pluralism and contentions over the universality of human rights conventions, the extent to which the UNESCO Declaration can motivate behaviors and policies rests, at least in part, upon accepting the moral arguments it makes. In this essay I reflect on a state's moral obligation to provide healthcare from the perspective of Islamic moral theology and law. I examine how Islamic ethico‐legal conceptual analogues for human rights and communal responsibility, ?uqūq al‐’ibād and far? al‐kifāyah and other related constructs might be used to advance a moral argument for healthcare provision by the state. Moving from theory to application, I next illustrate how notions of human rights and social responsibility were used by Muslim stakeholders to buttress moral arguments to support American healthcare reform. In this way, the paper advance discourses on a universal bioethics and common morality by bringing into view the concordances and discordances between Islamic ethico‐legal constructs and moral arguments advanced by transnational health policy advocates. It also provides insight into applied Islamic bioethics by demonstrating how Islamic ethico‐legal values might inform the discursive outputs of Muslim organizations.     

Die Buche. Eine Kultur‐ und Wirtschaftsgeschichte

The Beech forests: A cultural and socio‐economic history The German strategy of maintaining biodiversity aims at an establishment of wilderness areas. Mainly beech forests shall serve as UNESCO world heritage. Here we ask, if there are any “natural” beech forests. This tree species is closely linked to human development, and at present this species is less endangered than the accompanying species of Acer, Fraxinus, Quercus and other broad leaved species.     

Sampling phylogenetic tree space with the generalized Gibbs sampler

A recent article published in Cladistics is critical of a number of heuristic methods for phylogenetic inference based on parsimony scores. One of my papers is among those criticized, and I would appreciate the opportunity to make a public response. The specific criticism is that I have re‐invented an algorithm for economizing parsimony calculations on trees that differ by a subtree pruning and regrafting (SPR) rearrangement. This criticism is justified, and I apologize for incorrectly claiming originality for my presentation of this algorithm. However, I would like to clarify the intent of my paper, if I can do so without detracting from the sincerity of my apology. My paper is not about that algorithm, nor even primarily about parsimony. Rather, it is about a novel strategy for Markov chain Monte Carlo (MCMC) sampling in a state space consisting of trees. The sampler involves drawing from conditional distributions over sets of trees: a Gibbs‐like strategy that had not previously been used to sample tree‐space. I would like to see this technique incorporated into MCMC samplers for phylogenetics, as it may have advantages over commonly used Metropolis‐like strategies. I have recently used it to sample phylogenies of a biological invasion, and I am finding many applications for it in agent‐based Bayesian ecological modelling. It is thus my contention that my 2005 paper retains substantial value.     

Discovery of a new open-air Hoabinhian site in Luang Prabang province (Lao PDR). Dating and technological study of the lithic assemblage

The Hoabinhian is a distinctive lithic techno-complex of mainland and Island Southeast Asia. Knowledge of its relationships with key patterns of technological change at a global scale has progressed over the last two decades. However, our understanding of the Hoabinhian as an indicator of evolution during Prehistory can be substantially enhanced by examining its regional and chronological variability. Here, we present the characteristics of original Hoabinhian artefacts found in a new open-air site at Houay Pano, near Lak Sip (Luang Prabang province, Laos). This technological study of such a classic assemblage, including sumatraliths dated to 5.5 ± 0.6 ka, is a major contribution to Laotian prehistory and our understanding of the tempo-spatial variability of the Hoabinhian techno-complex.     

A longing for the natural past: unexplored benefits and impacts of a nostalgic approach toward restoration in ecology

Nostalgia has endured a negative societal perception since its inception, which influences how it is deployed in ecological restoration. However, the emotion has undergone a paradigmatic shift over the past 15 years with new quantitative psychological research providing insight into complex and oftentimes positive effects. In particular, personal nostalgia can increase social connectedness, optimism, self‐esteem, inspiration, openness, creativity, and charitable giving. Here, we view ecological nostalgia, which we define as a desire to return a degraded ecosystem to a past state that complements bittersweet memories of a better ecological period, as an accompanying motivator for applied ecological restoration. However, some restoration ecology circles presently reject the connection with nostalgia, which excludes potential benefits for restoration practices. We provide a survey of recent psychological nostalgia research to critique and reevaluate the stigma surrounding nostalgia in restoration. By doing so, we are optimistic that more informed views of nostalgia will be adopted by the restoration community to cautiously embrace a connection that can help motivate ecological restoration activities.     

Seeing (through) masks: An exploration of masks and mask making

In the form of a collage I juxtapose my experience of mask‐making with various interpretations of the nature and meaning of masks in order to explore the questions of whether masks can have meaning for those outside the culture of origin and whether encountering cultural artifacts like masks can enhance our own self‐understanding. I conclude, with some interpreters of masks, that the answer to these questions is in the affirmative, at least as a possibility.     

Building a science in Japan: The formative decades of Molecular Biology

I am honored to have been invited to participate in this Workshop on Comparative Studies of Building Molecular Biology, with a discussion of Japanese experiences in constructing a science — in this case, the discipline of molecular biology. As I understand it, the construction of a science must be equivalent to building a new culture. My having given this title to my paper suggests that I have enough knowledge about the subject to perhaps even extrapolate its course into the future — which I do not. What I do have is a sincere admiration of my old friends and colleagues, in Japan and elsewhere, who together tried to build a new science of molecular biology in Japan.     

A path to the powerhouse: systems‐to‐structure approaches for studying mitochondrial proteins

The young investigator award from the Protein Society was a special honor for me because, at its essence, the goal of my laboratory is to define what obscure proteins do. Years ago, I stumbled into mitochondria as a venue for this work, and these organelles continue to define the biological theme of my laboratory. Our approaches are fairly broad, reflecting my own somewhat unorthodox training among diverse scientific fields spanning organic synthesis, chemical biology, mechanistic biochemistry, signal transduction, and systems biology. Yet, whatever the theme or the discipline, we aim to understand how proteins work—especially those that hide in the dark corners of mitochondria. Below, I recount my own path into this arena of protein science, and describe how my experiences along the way have shaped our current multi‐disciplinary efforts to define the inner workings of this complex biological system.     

Symbolic ethnicity and symbolic religiosity: Towards a comparison of ethnic and religious acculturation

This article begins with a brief section updating my 1979 Ethnic and Racial Studies article ‘Symbolic ethnicity: the future of ethnic groups and cultures in America’. However, its main aim is to describe and develop the somewhat parallel concept of symbolic religiosity, which I conceive as the consumption of religious symbols apart from regular participation in a religious culture or in religious organizations, for the purpose of expressing feelings of religiosity and religious identification. Since I assume that symbolic religiosity develops mainly among the acculturating descendants of immigrants, I also explore the possibility of separating and then comparing ethnic and religious acculturation. I assume further that among religio‐ethnic groups like the Jews, and ethno‐religious groups such as Russian, Greek and other Orthodox Catholics, ethnic and religious acculturation proceed in divergent ways. This raises a number of interesting empirical questions about the differences between and similarities of ethnicity and religion among these groups and in general. The article concludes with speculations about what might happen to ethnicity and religiosity in the future. Most of my illustrative data in this article are drawn from studies and observations about American Jewry.     

Time at a Standstill: Loss,Accumulation, and the Past Conditional in an East Berlin Neighborhood

This article reconsiders the question of nostalgic consumption in East Germany as embedded not within a national or a regional (post-socialist) politics of time, as much literature has done, but rather within a global post-Fordist reconfiguration of the relation between time, consumption, and politics. Examining an underclass East Berlin neighborhood that has come to epitomize ‘pastness’, I show the salience of material prosperity – or its lack – in shaping the senses of time of its inhabitants. Especially for the younger generation, nostalgic commodities mediate the growing abyss between loss and accumulation, futures and pasts, nostalgic longings and unrealistic aspirations. I argue that the nexus of time, politics, and consumption has been transformed with the fading away of what has been called the future perfect (the political temporality of utopian projects) and its metamorphosis into what I term here the past conditional, the temporality of lost futures, irredeemable opportunities, and vanquished political imaginaries.     

Practical Nostalgia and the Critique of Commodification: On the ‘Death of Hockey’ and the National Hockey League

This paper explores some uses of nostalgia in two accounts of ‘the death of hockey’ in the professional National Hockey League of North America. The two accounts examined offer critiques of the commodification of the game some 26 years apart, in 1972 and in 1998. The argument developed here is that nostalgia can be more than just a longing or a yearning for an unattainable golden era located some unspecified time in the past, when social life was well organised and clearly understood, but rather that nostalgia can also take on a tough critical edge when its practical uses are recognised and exploited. Couched as practical nostalgia, such interpretations of the past provide a vision that can be used as a way of creating a space for the development of a critique of the present and opening up possibilities for the future. In the public culture of hockey practical nostalgia can be used to articulate a theoretical approach for understanding the ongoing commodification of the game.     

Plant tissue culture. Biotechnology. Milestones

Summary The progress in the development of the technologies of plant tissue and cell culture over the past four decades has been remarkable. This article covers my personal reflections on the various topics and is based on my involvement in the field during that period. There are three fundamental technologies which constitute most of what is referred to as plant in vitro technologies or tissue culture. The origin and some of the key persons involved in the development of each of these procedures will be discussed. The technology that is most common is growing plant tissue on gel-solidified nutrient media. That technology is being used in the most vital procedures, namely the regeneration of plants from cultured cells. The culture of plant cells in liquid suspension was developed very shortly after that, and has become a very effective technology for plant regeneration by somatic embryogenesis. The method of meristem culture arose out of a need for developing plants that were virus-free. In many species the technique is now being used to produce virus-free crop plants. Another important technology is the culture of anthers and microspores for producing haploid and homozygous plants. Included with plant tissue culture is the development of the plant protoplast and cell fusion technologies for the production of new plant hybrids. The final aspect of the development concerns the integration of tissue culture with molecular genetics, which has developed into the rapidly expanding field of biotechnology.     

‘Our bones are made of Iron’: the political ecology of Garhwali women's activism

In the Garhwal Himalaya of India's Uttarakhand State, a series of social movements emerged in the late 2000s to contest hydroelectric dams on a tributary of the sacred River Ganga. Within these opposition movements, men often took high‐profile leadership roles whereas women from a range of socio‐economic backgrounds formed the overwhelming base of participation at meetings, assemblies, and rallies. This article draws from event‐based participation and semi‐structured interviews to explore the diverse concerns that women gave to explain their engagements with opposition efforts. I counter essentialist frames and employ a feminist political ecology approach to argue that the gendered dynamics are attributable to historical, cultural, religious, and political‐economic influences. The article contributes to anthropologies of gender, environment, and social movements by taking an approach focused on disparities of practice and power that helps situate Garhwali women's roles in development contestations.
