ABSTRACT

Culture, by its very nature, is always at risk of change – whether through transformation, destruction or redefinition. So how might culture be said to be particularly at risk in the context of ‘natural’ disasters, and how are disasters ‘naturalised’ or incorporated under the terms of different cultural regimes? An earlier focus on the impacts to built or tangible heritage is increasingly being balanced by a concern for the transformations wrought by disasters in the intangible heritage of communities. Through the recent event of Cyclone Pam in 2015, and a case study of the World Heritage site of Chief Roi Mata’s Domain (CRMD), we explore the ways in which repetitive natural hazards have shaped culture and tangible and intangible forms of heritage in Vanuatu. We focus in particular on the issue of cultural transmission at CRMD and its relationship to natural hazards through the device of a ‘disaster biography’. Risk can also carry with it the prospect of opportunity, and our paper seeks to understand how opportunity might be present in post-disaster reworkings of culture and heritage.  相似文献

ABSTRACT

Oceanic people and places are increasingly labelled as either ‘resilient’ or ‘vulnerable’ to disasters and climate change. Resilience is often described in disaster discourse as a strategy designed to overcome vulnerability by helping communities to ‘bounce back’ in the wake of ‘natural’ disasters. Using ethnographic research conducted with Community Disaster and Climate Change Committees (CDCs) in Vanuatu in the wake of Tropical Cyclone Pam, this paper seeks to problematise disaster responses that see the ‘community’ as a space to be acted upon by outsiders, or where people will respond in a unified way to the challenges of rebuilding after disaster. Using political ecology framings this paper critiques the ideas of resilience that appear entrenched in community-based disaster and climate change adaptation discourse and practice in Oceania. Rather than presupposing resilience or vulnerability, this paper details the dispersal and distribution power and agency amongst individual actors and groups that either supported or manipulated, the distribution of goods by Community Disaster Committees. In this way, it moves beyond the limitations of conceptual framings of resilience in disaster management and climate change into a more considered appraisal of power, by exploring what James Ferguson has termed ‘the politics of distribution’ in the context of disaster.  相似文献

ABSTRACT

The establishment and use of community-based natural resource management (CBNRM) groups is now the established route towards conservation in large parts of the Pacific, especially in Fiji. One of the main strengths of CBNRM that is often mentioned is its adaptability to different contexts and to changing objectives among stakeholders, an aspect thoroughly tested by events such as ‘natural’ disasters. This paper is based on 10 months of fieldwork in Kubulau district in Fiji before, during and after Cyclone Winston. It provides an ethnographic account of how this ‘natural’ disaster affected a community and the local CBNRM group. It looks at how this event was experienced and managed by the group, and how the group’s involvement in disaster assistance shifted its role both within and outside of the community, as well as changing its future agenda during the months that followed. We can see in the aftermath of disaster a shift within the group away from the original primary focus on conservation and towards development. The paper provides an account of how the disaster seemingly strengthened the group and the ‘community’ in terms of organisation, knowledge and motivation, but also how it challenged previous norms and exposed weaknesses that are arguably inherent within CBNRM itself.  相似文献

ABSTRACT

Tongoa was one of the worst-hit islands in Vanuatu when it was struck on 13 March 2015 by Cyclone Pam, the most severe climatic event recorded in the South Pacific for several decades. Nearly all of the buildings on Tongoa were damaged by winds and flooding. However, exceptional this cyclone might have been, such disruptive events are frequent and widespread on Tongoa Island: landslides, volcanic eruptions, cyclones and droughts all contribute to shaping the universe of its inhabitants. This paper seeks to understand the category of disasta or ‘disaster’ and how it is constituted in the context of Tongoa Island, where there is no vernacular word to express the concept of catastrophe. Disasta is a subjective Bislama term, varying with circumstances, the impact of the phenomenon and the cultural and social identity of the group affected. Is there a threshold with which to measure and define disasters? Reflections from the perspective of an anthropology of nature and an anthropology of disaster reveal how considerations around the notion of catastrophe are closely intertwined with the relationships between people and their environment.  相似文献

ABSTRACT

Based on long-term doctoral fieldwork on bush fires in New Caledonia, this paper aims to explore the double assumption that bush fires were shaped as a public issue through specific categorisations of human and natural elements, and that this work resulted in negative outcomes as far as the environment is concerned. This paper will address the question of mediation between human agency (colonial history, population distribution and development choices) and the production of ‘bush fires’ as an event category and as a ‘public problem’ calling for a policy solution. More specifically it will address the validity of the definition of bush fires as a ‘disaster’. While this phenomenon is both a discursive creation rooted in colonial imagination and a consciously forgotten strategy used by administrators and settlers to control land and dominate indigenous people, its growing importance today is related to the emergence of environmental concerns. However, one must not forget other issues obscured by the smoke of bush fires, namely a declining cattle farming sector and its lasting environmental impacts on drought (also considered a ‘natural disaster’ in New Caledonia by inhabitants, local administrations and scientists) and biodiversity loss. Addressing this issue leads to more general questions about the manner in which policy-makers, naturalists and environmentalists conceptualise and morally address environmental (natural and man-made) phenomena through time in a colonial/postcolonial setting.  相似文献

For many good reasons, after natural disasters it is common to work with ‘memory’ as part of a collective catharsis and a globalized humanitarian logic. Long-term anthropological research on the aftermath of the 2001 earthquake in Gujarat, however, also demonstrates the significance of forgetting in local practice. Immediately after the disaster, people vowed to abandon the sites of their loss, leave the ruins as monuments, and rebuild anew on safer ground. In time, though, life returned to the ruins as the terrible proximity of death receded, as memories and new salience were shaped by acts of reconstruction. The article explores some of the political and social factors that make this form of forgetting possible – or even necessary. Evidence of earlier earthquakes in the same region indicates that such ‘forgetting’ has an established history. Together, ethnographic and archival materials combine to cast doubt over the emphasis on ‘remembering’ as the only ‘memory solution’ to suffering.  相似文献

Taking the example of ‘Studies in black and white’, a genre of photographs taken around the end of the nineteenth century by Methodist missionaries in the Pacific, this article seeks to go beyond conventional analyses that scrutinize colonial photography for forms of domination. I argue that these photographs, and the context in which some of them were published, reveal a complex interplay between two contradictory principles: on the one hand, a Christian humanism, articulating a vision of commonality and equality, and on the other, paternalism, articulating a vision of superiority and inequality .   相似文献

ABSTRACT

Providing emergency relief to the victims of natural disasters is a hugely complex process fraught with many challenging aspects: multiple uncertainties, little reliable information, scarcity of resources, a variety of involved entities, and so on. Nowadays there is a lot of information that could be used to improve decision-making in disaster management, but usually it is not available at the right moment, in the right way, or it is partially known or vague. In this article we analyze the decision-making process for disaster management from the general view of intelligent decision-making to the specific characteristics of this context. This specificity deals with a new kind of logistics, and it is shown how this humanitarian logistics, specifically designed with the aim of alleviating suffering of vulnerable people, is a growing new research area to develop new decision aid models for disaster management, identifying new and relevant differences with other types of logistics. To illustrate these claims, two models are introduced, one for assessment of consequences in the earlier stage after a disaster (focused on the unknown, one of the main characteristics in disaster management), and another one for last mile distribution of humanitarian aid (focused on the multicriteria nature of decision-making on disaster management).  相似文献

Abstract

Constructing scientific explanations of natural phenomena is an important aim of science education. Explanation oriented science teaching approaches encourage learners to engage in sense-making discussions and construct the causal accounts of the phenomena under study. This article demonstrates a lesson-design model that guides biology teachers on how to integrate explanation oriented teaching in their everyday practice. The proposed model includes six phases: (1) presenting a hooking activity; (2) formulating a how-why type focus question; (3) constructing the initial causal story; (4) using authentic data, scientific facts, principles, and disciplinary core ideas to revise-refine the causal story; (5) discussing-rewriting the refined causal story; (6) applying the causal-mechanistic knowledge in a new context or problem scenario. An eleventh-grade lesson on the topic ‘protein biosynthesis in cells’ serves an example about how this model can be operationalized to design and implement explanation oriented biology lessons.  相似文献

BackgroundThe most demanding challenge in research on molecular aspects within the flow of biological information is posed by the complex carbohydrates (glycan part of cellular glycoconjugates). How the ‘message’ encoded in carbohydrate ‘letters’ is ‘read’ and ‘translated’ can only be unraveled by interdisciplinary efforts.Scope of reviewThis review provides a didactic step-by-step survey of the concept of the sugar code and the way strategic combination of experimental approaches characterizes structure–function relationships, with resources for teaching.Major conclusionsThe unsurpassed coding capacity of glycans is an ideal platform for generating a broad range of molecular ‘messages’. Structural and functional analyses of complex carbohydrates have been made possible by advances in chemical synthesis, rendering production of oligosaccharides, glycoclusters and neoglycoconjugates possible. This availability facilitates to test the glycans as ligands for natural sugar receptors (lectins). Their interaction is a means to turn sugar-encoded information into cellular effects. Glycan/lectin structures and their spatial modes of presentation underlie the exquisite specificity of the endogenous lectins in counterreceptor selection, that is, to home in on certain cellular glycoproteins or glycolipids.General significanceUnderstanding how sugar-encoded ‘messages’ are ‘read’ and ‘translated’ by lectins provides insights into fundamental mechanisms of life, with potential for medical applications.  相似文献

Wildlife management methods such as culling (lethal control) and fencing can be controversial in some circumstances. Such controversy can be problematic for decision-makers or those managing decision-making processes and can lead to management delays or inertia. Understanding the reasons why people support or oppose specific management methods is therefore an important objective for researchers. Attitudes towards methods are in part based on individual beliefs about those methods, the species of wildlife being managed and other associated phenomena. This paper adopts a qualitative approach to develop understanding of these beliefs. We conducted 17 focus-groups on wild deer management at two locations in Britain, with both ‘professional’ land manager and ‘public’ participants (n?=?103). We identified a number of individual beliefs which are grouped into five categories: naturalness, overabundance, impacts, effectiveness and animal welfare. Our findings suggest that potentially controversial management methods will receive most support where the objective is to maintain a ‘natural’ environment, at sites where impacts are evident, and when using targeted and effective methods.  相似文献

ABSTRACT

International practices of disaster preparedness presume human agency, particularly at the household level, as an important pre-emptive response to anticipated natural hazards. Our analysis of Fijian responses to Tropical Cyclone Winston indicates that preparedness is also regarded as important by cyclone survivors but has a moral dimension that can be used to assign blame to underprepared members of the community. However, Fijian villagers’ experiences of terror and awe during Tropical Cyclone Winston also make them aware of the limits of human agency, prompting them to reflect on God’s role in the cyclone and the need for collective repentance and renewed Christian commitment. The effectiveness of disaster preparedness and climate change adaptation efforts can only be enhanced by a better understanding of the values of affected communities, including religious and spiritual values. We seek to contribute to this knowledge by showing how disaster preparedness both converges with and diverges from Fijian Christian practices.  相似文献

BackgroundMarine algae are rich in some unique biologically active secondary metabolites having diverse pharmacological benefits. Of these, sterols comprise a group of functional lipid compounds that have attracted much attention to natural product scientists.PurposeThis review was aimed to update information on the health effects of algae-derived phytosterols and their molecular interactions in various aspects of human health and diseases and to address some future perspectives that may open up a new dimension of pharmacological potentials of algal sterols.MethodsA literature-based search was carried out to retrieve published research information on the potential health effects of algal phytosterols with their pharmacological mechanisms from accessible online databases, such as Pubmed, Google Scholar, Web of Science, and Scopus, using the key search terms of ‘marine algae sterol’ and ‘health potentials such as antioxidant or anti-inflammatory or anti-Alzheimer's or anti-obesity or cholesterol homeostasis or hepatoprotective, antiproliferative, etc.’ResultsPhytosterols of marine algae, particularly fucosterol, have been investigated for a plethora of health benefits, including anti-diabetes, anti-obesity, anti-Alzheimer's, antiaging, anticancer, and hepatoprotection, among many others, which are attributed to their antioxidant, anti-inflammatory, immunomodulatory and cholesterol-lowering properties, indicating their potentiality as therapeutic leads. These sterols interact with enzymes and various other proteins that are actively participating in different cellular pathways, including antioxidant defense system, apoptosis and cell survival, metabolism, and homeostasis.ConclusionIn this review, we briefly overview the chemistry, pharmacokinetics, and distribution of algal sterols, and provide critical insights into their potential health effects and the underlying pharmacological mechanisms, beyond the well-known cholesterol-lowering paradigm.  相似文献

ABSTRACT

Introduction: Recently, the classification of two ‘novel’ organs, the mesentere and interstitium, was saluted as a scientific breakthrough and disseminated into mainstream media. The novelty of these findings did not pertain to the characterization of some previously unexplored phenomena, rather to the appreciation that well-established tissues may play some hitherto unexplored functions critical to system homeostasis.

Areas covered: Here we provocatively comment on the potential classification of red blood cells – by far the most abundant host cell in the human body (~ 83% of the total cells) – as an organ involved in many functions beyond gas transport. In this perspective article, we describe some of these functions with a special emphasis on the role erythrocytes play with respect to systemic metabolic homeostasis. We thus focus on how these functions modulate the cross talk of red blood cells among each other and with other cell types including immune cells.

Expert commentary: The appreciation of RBCs as an organ impacting systemic metabolic homeostasis and other cell functions while engaging in complex metabolic activity beyond oxygen transport can foster the development of novel therapeutic interventions in pathologic hypoxemia, inflammation, neurodgenerative diseases, aging, and cancer.  相似文献

Introduction: Epigenetic dysregulation drives or supports numerous human cancers. The chromatin landscape in cancer cells is often marked by abnormal histone post-translational modification (PTM) patterns and by aberrant assembly and recruitment of protein complexes to specific genomic loci. Mass spectrometry-based proteomic analyses can support the discovery and characterization of both phenomena.

Areas covered: We broadly divide this literature into two parts: ‘modification-centric’ analyses that link histone PTMs to cancer biology; and ‘complex-centric’ analyses that examine protein–protein interactions that occur de novo as a result of oncogenic mutations. We also discuss proteomic studies of oncohistones. We highlight relevant examples, discuss limitations, and speculate about forthcoming innovations regarding each application.

Expert commentary: ‘Modification-centric’ analyses have been used to further understanding of cancer’s histone code and to identify associated therapeutic vulnerabilities. ‘Complex-centric’ analyses have likewise revealed insights into mechanisms of oncogenesis and suggested potential therapeutic targets, particularly in MLL-associated leukemia. Proteomic experiments have also supported some of the pioneering studies of oncohistone-mediated tumorigenesis. Additional applications of proteomics that may benefit cancer epigenetics research include middle-down and top-down histone PTM analysis, chromatin reader profiling, and genomic locus-specific protein identification. In the coming years, proteomic approaches will remain powerful ways to interrogate the biology of cancer.  相似文献

ABSTRACT

This article explores the notion that peoples speaking Austronesian languages brought the ideology of social hierarchy based on hereditary leadership into the Pacific Islands. This social model contrasts with the strongly egalitarian leadership that likely characterised peoples already residing in New Guinea and nearby islands. While complex interactions between these two groups did occur, particularly in coastal areas, the latter populations rarely adopted hierarchical models of leadership. In contrast, the institution of hereditary leadership burgeoned into elaborate chiefdoms as Austronesian speakers expanded into Remote Oceania. Using linguistic and archaeological evidence, we argue that hereditary leadership, or the institutions to support it, may already have been in place in early Austronesian societies in Taiwan. We further evaluate this correlation by reviewing ethnographic reports of chiefs and reanalysing scholarly appraisals of big-man societies and chiefdoms. We conclude that the ‘Melanesian big-man vs. Polynesian chief’ contrast corresponds largely to the Austronesian and Non-Austronesian language divide; attention to which can clarify the development of hereditary leadership in the Pacific and illuminate historical relations among cultures in Near Oceania.  相似文献

BackgroundIn order to improve the effectiveness and efficiency of humanitarian efforts, minimum standards for humanitarian assistance and key indicators, showing whether a standard has been attained, have been developed. However, many of these standards and indicators are based on a consensus on best practices and experiences in humanitarian response, because relevant evidence on the impact of humanitarian interventions is often lacking.ObjectivesOne important example of a standard in humanitarian aid in a disaster setting is “water quantity.” The accompanying indicator states how many litres of water are needed per person per day in a disaster setting. It was our objective to determine the evidence base behind this indicator, in order to improve health outcomes such as morbidity (e.g., diarrhoea) and mortality.MethodsA systematic review was performed searching The Cochrane Library, Medline and Embase. We included studies performed during disasters and in refugee camps that reported a specific water amount and health-related outcomes related to water shortages, including diarrhoea, cholera, and mortality. We used GRADE to determine the quality of evidence.ResultsOut of 3,630 articles, 111 references relevant to our question were selected. Based on our selection criteria, we finally retained 6 observational studies, including 1 study that was performed during the disaster and 5 studies in a post-disaster phase. From two studies there is conclusive evidence on the relationship between the amount of water received and diarrhoea or mortality rates in refugee camps. However, overall, these studies do not contain enough data with relevance to a specific amount of water, and the level of evidence is very low.ConclusionsMore primary research on water amounts in a disaster setting is necessary, so that the humanitarian sector can further professionalise its water-related standards, indicators and interventions.  相似文献

Summary

This is a review of some problems posed by research on tree biology. First, phase change and in vitro culture are discussed as they affect vegetative propagation of woody plants. Then the breeding of timber trees, with an evident and important trend to clonal propagation is considered. Tropical timber tree breeding has enormous potential but has only just started (on very few species). The trend to making tropical woodlands into planted pure stands, of converting production forestry into, ‘tree farming’, an aspect of agriculture, so to speak, is apparent. ‘Ideotypes’ have fallen out of favour but some important ideas as to biomass and its allocation remain and well-defined economic objectives must become paramount. A broad review of the tropical agricultural context with regard to trees, suggests an acute need for far better understanding of them and for much introduction and breeding to generate new woody food-crops.  相似文献

ABSTRACT

Together, radio and mobile phones have been the object of many political expectations held by development actors in Africa. Stating that they enable ‘participation’ is, however, not enough to understand what is at stake in a given context. It is necessary to describe exactly the kind of participation taking place. Despite development projects inceptors’ intentions, the way people use ICT (information and communication technologies) objects sometimes leads to a rerouting of their political meaning. This article deciphers these sideway uses and what they imply in the Ugandan context. Based on the example of ‘serial callers' (people who intensively call in during radio talk shows), it demonstrates that ICT objects become the site of the elaboration of particular ways of conceiving one's roles, status and duties in the polity, as an ‘educator’ or a ‘representative’, blurring established distinctions between political representation and participation, and offers a nuanced picture of the complexities of patronage politics.  相似文献
