Using the case of food safety governance reform in Japan between 2001 and 2003, this paper examines the relationship between
science and trust. The paper explains how the discovery of the first BSE positive cow and consequent food safety scandals
in 2001 politicized the role of science in protecting the safety of the food supply. The analysis of the Parliamentary debate
focuses on the contestation among legislators and other participants over three dimensions of risk science, including “knowledge,”
“objects,” and “beneficiaries.” The metaphor of “seven samurai” and the relationally situated roles of “samurai,” “bandits,”
and “beneficiaries” are used to show that in the process of policy making certain moral and ethical expectations on a new
expert institution for food safety were contested and negotiated to frame responsibilities and commitments of social actors for creating the food
system based on trust.

This paper examines the discourses and practices of pedigree livestock breeding, focusing on beef cattle and sheep in the
UK, concentrating on an under-examined aspect of this—the deselection and rejection of some animals from future breeding populations.
In the context of exploring how animals are valued and represented in different ways in relation to particular agricultural
knowledge-practices, it focuses on deselecting particular animals from breeding populations, drawing attention to shifts in
such knowledge-practices related to the emergence of “genetic” techniques in livestock breeding which are arguably displacing
“traditional” visual and experiential knowledge’s of livestock animals. The paper situates this discussion in the analytical
framework provided by Foucault’s conception of “biopower,” exploring how interventions in livestock populations aimed at the
fostering of domestic animal life are necessarily also associated with the imperative that certain animals must die and not
contribute to the future reproduction of their breed. The “geneticization” of livestock breeding produces new articulations
of this process associated with different understandings of animal life and the possibilities of different modes of intervention
in livestock populations. Genetic techniques increasingly quantify and rationalize processes of selection and deselection,
and affect how animals are perceived and valued both as groups and as individuals. The paper concludes by emphasizing that
the valuation of livestock animals is contested, and that the entanglement of “traditional” and “genetic” modes of valuation
means that there are multiple layers of valuation and (de)selection involved in breeding knowledge-practices. 相似文献

This paper contributes to the growing social science scholarship on organic agriculture in the global South. A “boundary”
framework is used to understand how negotiation among socially and geographically disparate social worlds (e.g., non-governmental
organizations (NGOs), foreign donors, agricultural researchers, and small-scale farmers) has resulted in the diffusion of
non-certified organic agriculture in Kenya. National and local NGOs dedicated to organic agriculture promotion, training,
research, and outreach are conceptualized as “boundary organizations.” Situated at the intersection of multiple social worlds,
these NGOs engage in “strategic bridge building” and “strategic boundary-work.” Strategic bridge building involves the creation
and use of “boundary objects” and “hybrid forms” that serve as meeting grounds for otherwise disconnected social worlds. Strategic
boundary-work involves efforts to “scientize,” and thereby legitimize, organic agriculture in the eyes of foreign donors,
potential research collaborators, the Kenyan state, and farmers. Examples of strategic bridge building and boundary-work are
presented in the paper. The Kenyan case illustrates that different social actors can unite around a shared objective – namely,
the promotion and legitimization of organic agriculture as an alternative to the Green Revolution (GR) technological package.

There has been widespread academic and popular debate about the transformative potential of consumption choices, particularly
food shopping. While popular food media is optimistic about “shopping for change,” food scholars are more critical, drawing
attention to fetishist approaches to “local” or “organic,” and suggesting the need for reflexive engagement with food politics.
We argue that reflexivity is central to understanding the potential and limitations of consumer-focused food politics, but
argue that this concept is often relatively unspecified. The first objective of this paper is to operationalize reflexivity
and advance understanding of reflexivity as an important tool for understanding the lived experience of food shopping. Our
second objective is to explore the range of reflexivity observed in a mainstream “shopping for change” market sector. To do
this, we draw from in-depth interviews with shoppers at Whole Foods Market (WFM)—a retail venue with the stated goal of making
consumers “feel good about where [they] shop.” This group is chosen because of our interest in investigating the reflexivity
of consumer engagement with the corporatized arm of ethical consumption—a realm of concern to food scholars as alternative
agricultural initiatives are absorbed (both materially and symbolically) into corporate institutions. Our analysis suggests
that shopping at venues like WFM is primarily motivated by traditional consumer pleasures, even for politicized consumers,
a finding that poses serious limitations for a consumer-regulated food system. 相似文献

Based on fieldwork in northern Senegal, this paper shows how some pastoralists in Ferlo have managed to use market opportunities
as a means to maintain their “pastoral way of life” Increased market involvement has enlarged the field of opportunities for
pastoral activities as well as the vulnerability of these activities. This has given rise to a dialectic process of diversification
and specialization. The paper is concerned with the portfolio of livelihood activities pastoralists use in order to respond
to adverse socio-economic and environmental conditions. Depending on the possibilities and values of a household, a certain
combination of activities is chosen and this may change from one year to another. Hence, the activities are used in a dynamic
way within households. On the basis of pastoral livelihood activities, four ideal types of pastoral livelihood strategies
can be constructed: “agro-pastoralism,” “Tabaski pastoralism,” “commercial pastoralism,” and “non-herding pastoralism.” These
four types illustrate how pastoralists re-invent their livelihoods in order to continue a pastoral way of life.

Formation causes and recovery of the “Black Soil Type” degraded alpine grassland in Qinghai-Tibetan Plateau 总被引:1,自引:0,他引:1
The formation causes and ecological rebuilding of the “Black Soil Type” degraded alpine grassland are summarized. The formation
of the “Black Soil Type” degraded grassland was caused mainly by climate warming, decreasing glaciers, overgrazing, and damage
by rats. The ecological restoration of the “Black Soil Type” degraded alpine grassland relies not only on grassland building,
but also on reasonable management and planning of grassland resources. Guaranty measures for developing the alpine grassland
animal husbandry in a healthy way include intensifying the educational investment in pasture regions, practicing long-term
contracts for grassland, and strengthening the grassland legislation. The authors believe that the Qinghai-Tibetan Plateau
ecosystem has a special characteristic intertia or “inert gases”, which weaken the self-renewing capability of the ecosystem
and makes its structure frail. The inertia characteristic may be the important reason that makes ecological rebuilding so
difficult; in addition, other problems need to be studied deeply to provide scientific bases for the ecological building in
the Qinghai-Tibetan Plateau.

Lack of automatic weed detection tools has hampered the adoption of site-specific weed control in cereals. An initial object-oriented
algorithm for the automatic detection of broad-leaved weeds in cereals developed by SINTEF ICT (Oslo, Norway) was evaluated.
The algorithm (“WeedFinder”) estimates total density and cover of broad-leaved weed seedlings in cereal fields from near-ground red–green–blue images.
The ability of “WeedFinder” to predict ‘spray’/‘no spray’ decisions according to a previously suggested spray decision model for spring cereals was
tested with images from two wheat fields sown with the normal row spacing of the region, 0.125 m. Applying the decision model
as a simple look-up table, “WeedFinder” gave correct spray decisions in 65–85% of the test images. With discriminant analysis, corresponding mean rates were 84–90%.
Future versions of “WeedFinder” must be more accurate and accommodate weed species recognition. 相似文献

Over the course of the 1990s, donor enthusiasm for participation came to be institutionalized in a variety of ways. One particular
methodology—Participatory Rural Appraisal (PRA)—came to enjoy phenomenal popularity. New aid modalities may have shifted donor
and lender concern away from the grassroots towards “policy dialogue.” But “civil society participation,” “social accountability,”
and “empowerment”—some of the issues PRA grapples with—retain a place in the new aid discourse. PRA and its variants also
continue to be used by government agencies, non-governmental, and community-based organizations in local-level assessment,
planning, monitoring, and evaluation, as well as in national-level poverty assessments. It has sometimes been conflated, by
donors and critics alike, with doing participatory development, and has elicited critiques that often go far beyond the bounds
of the methodological. Yet these critics have tended to be academics with little experience as practitioners or facilitators.
In this article, we draw on an action research project with PRA practitioners. We explore, through their critical reflections,
some of the conundrums and contradictions faced by those who were active as PRA practitioners in the early 1990s. We suggest
that the story of PRA’s success and of subsequent concerns about abuse and misuse by mainstream development institutions offers
broader lessons with continued salience for development. 相似文献

Changing land-use patterns and amenity-driven migration have brought agriculture back into people’s lives, but there is a
disconnection between the realities of production agriculture and romantic images attached to farming. To the extent that
“rurality” is attached to farming, people may desire to live in rural places, but they may be unprepared for the realities
of living near a working farm. Greater numbers of communities are facing “either/or” outcomes regarding the conversion of
“open space” land to residential or commercial uses versus landscape preservation. This study explored the perceptions and
preferences of a community regarding the conversion of a hypothetical parcel of open space to a working dairy or to a residential
subdivision. Results suggest that the opportunity costs of foregoing open space for residential development are high, with
implications for valuing the conservation of traditions that are tied to the land versus conversion of land solely for development
purposes. 相似文献
