ABSTRACT

Community-driven development in Indonesia requires the recruitment of volunteers: local residents with the will to develop themselves and others. By revealing the processes of personhood in light of volunteers’ own theories of self, I aim to disrupt simple readings of subjectification in the anthropology of development. Local volunteers understand their recruitment as having the opportunity to occupy a social position that is aligned with their jiwa (nature), and their participation as satisfying their hati (seat of emotion). Rather than assess the success or failure of state actions to regulate or constitute citizens through discursive and affective means, I take seriously this understanding of development as a process of locating and recruiting people predisposed to becoming the subjects of state development. Doing so prompts new lines of enquiry that have been overlooked in understanding processes of subjectification in development: namely the reason why some people are recruited as development subject, while the majority are not.  相似文献

Given near unanimity in the environmental and industrial communities about the need for a new generation of environmental technology, the policy process unfortunately lags behind in moving toward this objective. This article examines causes and remedies for this gap in the context of American environmental policy. U.S. environmental laws continue to be pervaded by structural biases against new technology, and the complexity of their administration exacerbates the problem. Within the last few years, several important reform initiatives have arisen from inside the regulatory community; however, these can only go so far, given the current statutory framework Congress, too long quiescent, needs to become involved. A legislative reform package is proposed consisting of four main elements: a legislative mandate that makes promotion of technological innovation an explicit environmental objective; elimination of structural features in current law that impede innovation; creation of a new framework for standard-setting and enforcement that puts every firm on a trajectory toward environmental and technological improvement; and enlisting regulation as a "demand-pull" for environmentally superior technology.  相似文献

One of the most relevant topics in the biology of invasion concerns the genetic changes that occur subsequent to a species invasion, an issue of particular focus among conservation biologists. Colonizing a novel environment presents a genetic challenge to invading species because such species surely have not experienced the selective pressures presented by the environment. Here we ask, by what mechanisms and processes do alien species genetically naïve to their new environment, become successful invaders? We attempt to resolve this paradox by considering the interplay between an invader’s ability to modify its new environment, and genetic modifications imposed by the new environment. We postulate that epigenetic adaptations, and adaptive mutations are likely play a role in enhancing invasion success.  相似文献

Recent trends in ecological restoration complicate the job of wilderness managers. An emphasis on volunteer participation in restoration designed to foster human/nature relationships often conflicts with the mandate to leave land untrammeled. We frame this conflict as the “participation paradox.” Higgs’ (2003) Nature by Design contains a response to the paradox that includes a strong defense of participatory focal restoration and a related critique of wilderness. After identifying the limitations of Higgs’ arguments, we address the paradox by showing how an appeal to the moral virtues of humility, self‐restraint, and altruism supports a restrictive conception of wilderness and a healing metaphor for wilderness restoration. The virtue‐informed healing metaphor provides an argument for restricting volunteer participation and long‐term restoration projects in wilderness areas. It also identifies the general conditions in which damaged wilderness should be allowed to “heal itself.” The upshot of our approach to the paradox is that some standards for good restoration should be contextualized to land use designations. In particular, the emphasis on participatory restoration is appropriate in humanized landscapes but not in wilderness.  相似文献

This paper focuses on the social media presence of Black Lives Matter (BLM). Specifically, we examine how social media users interact with BLM by using hashtags and thus modify the framing of the movement. We call this decentralized interaction with the movement “distributed framing”. Empirically, we illustrate this idea with an analysis of 66,159 tweets that mention #BlackLivesMatter in 2014, when #BlackLivesMatter becomes prominent on social media. We also tally the other hashtags that appear with #BlackLivesMatter in order to measure how online communities influence the framing of the movement. We find that #BlackLivesMatter is associated with five types of hashtags. These hashtags mention solidarity or approval of the movement, refer to police violence, mention movement tactics, mention Ferguson, or express counter-movement sentiments. The paper concludes with hypotheses about the development of movement framings that can be addressed in future research.  相似文献

A Monte Carlo model of a multi-species community with a single trophic level, with nutrients supplied randomly in space and time, demonstrates an irreducible variability in species number and composition. Competition between closely similar species does not necessarily proceed to the elimination of the less efficient species because the variability in food supply becomes a more important factor in survival than does even a fairly large difference in efficiency.  相似文献

The Factor X Debate: Setting Targets for Eco-Efficiency   总被引:2,自引:0,他引:2  
The quantification and achievement of eco-efficiency or dematerialization in the form of a factor X, with X varying between 4 and 50 is being espoused by a variety of analysts and advocates. Politically, these efforts are mainly confined to some European countries. They reflect a remarkable technological optimism. This article reviews some of the major issues pertinent to the factor X debate. The case is presented for quantifying dematerialization or eco-efficiency goals using a factor X. It is also found that the factor X lacks precision as yet, and that there is only limited interest in the possibilrty that achievable values for X may vary widely among economic activities given technological constraints. There is no agreement whether technological improvement alone will be sufficient to achieve a factor X in practice for economies as a whole. It seems likely, however; that government-driven technology forcing will be necessary to achieve a factor X in practical terms, especially when X is relatively large.  相似文献

Background. The 7th Framework Programme for Research and Technological Development is helping the European Union to prepare for an integrative system for intelligent management of biodiversity knowledge. The infrastructure that is envisaged and that will be further developed within the Programme “Horizon 2020” aims to provide open and free access to taxonomic information to anyone with a requirement for biodiversity data, without the need for individual consent of other persons or institutions. Open and free access to information will foster the re-use and improve the quality of data, will accelerate research, and will promote new types of research. Progress towards the goal of free and open access to content is hampered by numerous technical, economic, sociological, legal, and other factors. The present article addresses barriers to the open exchange of biodiversity knowledge that arise from European laws, in particular European legislation on copyright and database protection rights.We present a legal point of view as to what will be needed to bring distributed information together and facilitate its re-use by data mining, integration into semantic knowledge systems, and similar techniques. We address exceptions and limitations of copyright or database protection within Europe, and we point to the importance of data use agreements. We illustrate how exceptions and limitations have been transformed into national legislations within some European states to create inconsistencies that impede access to biodiversity information.Conclusions. The legal situation within the EU is unsatisfactory because there are inconsistencies among states that hamper the deployment of an open biodiversity knowledge management system. Scientists within the EU who work with copyright protected works or with protected databases have to be aware of regulations that vary from country to country. This is a major stumbling block to international collaboration and is an impediment to the open exchange of biodiversity knowledge. Such differences should be removed by unifying exceptions and limitations for research purposes in a binding, Europe-wide regulation.  相似文献

PurposeThough the number of women scientists is increasing over the years, studies show that they are still under-represented in leadership roles. The purpose of this work is to establish the percentage of women Medical Physicists (wMPs) that have participated in European scientific events and evaluate it as an indication of the current position of women in the field of Medical Physics in Europe and to propose possible ways to encourage their participation.Materials and MethodsData regarding the participants in European scientific events of Medical Physics were collected. The participants were divided into categories according to the program of the events and their gender was identified. The percentage of wMPs in each category was evaluated.ResultsThe participation of wMPs attending courses is greater than 50%. The categories with the greatest participation are “Organizing Committees”, “Chairpersons-Moderators” and “Oral Presentations”. The categories with the lower participation of wMPs are “Scientific Committee”, “Symposiums” and “Invited Speakers”. None of wMPs were represented as “Course Directors”.ConclusionsThe attendance of wMPs in courses is slightly greater than average. However, wMPs do not have an equally important recognition in special invited roles in conferences. They are still under-represented in “Scientific Committees”, “Invited Speakers”, “Symposiums” and “Course directors”. wMPs should be encouraged to participate even more actively in European conferences and the organizing committees should invite more wMPs in special roles. More studies concerning the status of female MPs in each country separately should be encouraged as they will help in understanding the position of wMPS in Europe.  相似文献

The work of a bioethicist carries distinctive responsibilities. Alongside those of any worker, there are responsibilities associated with giving guidance to practitioners, policy makers and the public. In addition, bioethicists are professionally exposed to and required to identify situations of moral trouble, and as a result may find themselves choosing to work as advocates or activists, with responsibilities that are distinct from those generally acknowledged within academia. The requirement for bioethics to make normative judgements entails taking a stance, which means there cannot be a sharp line between ‘academic’ or ‘objective’ bioethics, and advocacy/activism, but a continuum of bioethicists’ engagement and an associated continuum of responsibilities.  相似文献

Alliances are a political opportunity that reinforce the claims made by different players in the political sphere. However, the literature on the political participation of immigrants pays little attention to the formation of alliances and their effects on the interaction between immigrants and institutional actors, especially under circumstances of politicization. This article aims to explain the emergence of alliances between political parties and immigrant organizations when immigration is politicized locally. I argue that the need to legitimize the political parties’ position on the politicization guide their alliances with immigrants. Using qualitative methods, I analyse the emergence of alliances in the anti-Romanian-Roma campaign in Badalona and the burka ban in Lleida, both in Catalonia, Spain. The findings portray these relationships as the outcome of strategic interactions that respond to the balance of power between institutional and non-institutional actors.  相似文献

Paraquat is an herbicide used extensively in agriculture and has also been proposed to be a risk factor for Parkinson's disease. To date, experimental, clinical, and epidemiological data on paraquat neurotoxicity have been equivocal. In this short review, we discuss some technical and biological mechanisms that contribute to inconsistencies regarding paraquat neurotoxicity. We hypothesize that individual genetic variations in susceptibility generate major differences in neurotoxic risk and functional outcome. Identifying these heritable sources of variation in host susceptibility, and their role in complex gene–environment interactions, is crucial to identify risk biomarkers and to devise better prevention and treatment for those exposed to paraquat and other potential neurotoxicants.  相似文献

This study aims to investigate the impact of consumer familiarity with edible insect food products on purchase intentions and expected liking. Based on persuasion and information processing theories, this study examines the roles of media trust and purchase activism as underlying psychological mechanisms. The findings of this study indicate that consumer familiarity contributes to the formation of media trust. It adds credibility to the media information and consumers can be more motivated to exercise their purchase activism as the edible insect food movement is closely related to social causes like sustainability. Activist motivation, then, changes consumers' behavioral outcomes such as purchase intention and expected liking of edible insect food products.  相似文献

The ethnoecology of maize variety management: A case study from Mexico   总被引:3,自引:0,他引:3  
This paper presents a case study of the relationship between farmers' knowledge of maize varieties and their selection and management of these varieties under conditions of technological change. Research for this paper was done among Spanish-speaking small farmers in an ejidoof central Chiapas, Mexico. This ejido is well integrated into the market, and the use of modem technologies is widespread. This research demonstrates that farmers have an extensive and widely shared knowledge of their maize varieties. This knowledge reflects objective maize characteristics. Variation occurs in the farmers' selection and management of maize varieties, but on average the variation deviates from a random pattern in the direction predicted by the farmers' knowledge base. They have incorporated the technological changes brought about by development into their knowledge base. Farmers maintain maize varieties with contrasting traits, and their knowledge base provides important information about which traits and constraints are important to them.  相似文献

Archaeologists have long recognized that increases in political centralization often coincide with the growth of regional settlement hierarchies. Here I develop a theoretical model which explicitly relates certain aspects of political complexity to variation in settlement size. This model applies specifically to hierarchical societies without well-developed market economies—societies which Service would classify as chiefdoms and (perhaps) simple states. Using settlement data from the Formative Period Valley of Mexico, I show how this model is useful in measuring (1) the number of levels in a regional hierarchy, (2) the degree of political centralization, and (3) the relative amount of surplus food mobilized to support the political establishment.  相似文献
