This paper examines capacity-building measures used by the health sector relevant to natural resource management (NRM) using
the delivery of two programs in Australia through its recently formalized 56 community-based regional NRM Boards as a reference
point. The delivery of NRM outcomes through devolved governance arrangements has been hampered by inadequate capacity in other
countries (e.g., New Zealand, Canada). The inherent complexities of NRM, coupled with professional “comfort zones,” often
limit actors from looking to other sectors confronting similar issues. This paper summarizes findings from ∼70 sources in
health reviewing nine major capacity-building measures. The outcomes of research evaluating the relative benefits and disbenefits
of applying these measures are discussed. The paper identifies several opportunities to trial some of these measures in NRM.

What Happens to Traditional Knowledge and Use of Natural Resources When People Migrate? 总被引:2,自引:2,他引:0
Ingrid Nesheim Shivcharn S. Dhillion Kristi Anne Stølen 《Human ecology: an interdisciplinary journal》2006,34(1):99-131
The study investigates traditional knowledge of forest plants in a community (La Quetzal) inhabited by people who returned
to Guatemala at the end of the civil war, after 10–12 years in exile in Southern Mexico, and now are in the process of constructing
a new community in the Lacandon jungle in the Petén, Guatemala. We ask if the basis of knowledge and the use of natural resources
change when people migrate. The relevance of vascular plant diversity for consumption and other daily needs of the population
is explored. Relatively few species are presently used, with the exception of timber species, where knowledge seems to be
increasing. Traditional knowledge has been maintained in certain areas such as medicine. Nature as such is regarded as important
primarily as potential monetary capital and not for its subsistence capital. We find that the refugee situation has led to
the introduction of global consumption patterns. Still there continues to be a dynamic local intuitive knowledge arising directly
from practical experiences. Two interlinked factors have been the driving forces altering the knowledge and the use of natural
resources by the people in La Quetzal: Change in the natural environment and change in the social and economic environment.

This paper introduces a threshold policy with hysteresis (TPH) for the control of one-predator one-prey models. The models studied are the Lotka–Volterra and Rosenzweig–MacArthur
two species density-dependent predator–prey models and the Arditi–Ginzburg nondimensional ratio-dependent model. The proposed
policy (TPH) changes the dynamics of the system in such a way that a bounded oscillation is achieved confined to a region
that does not allow extinction of either species. The policy can be designed by a suitable choice of so called virtual equilibrium
points in a simple and intuitive manner.

As neoliberalism continues to influence environmental governance, it affects notions about the appropriate level of community
involvement in resource management. Under more recent iterations, hybrid forms of governance are emphasized, including government–civil
society partnerships and approaches geared towards harnessing the strengths of local communities. Here we explore the characteristics
of different resource management rights, strategies, and tools through which communities can find political space to assert
their own agendas within a neoliberalized policy environment. We examine the successful use of some of these approaches by
communities during the initial development of community forests policy and practice in British Columbia, Canada. While we
confirm the complex, contingent and case-specific nature of opportunities for comanagement created through neoliberal policy
elements, we suggest that space does exist for community forest bodies to assert local values, goals and strategies, demonstrating
the creativity, ingenuity and determination of communities to attain a real voice in management.

Debates over adaptationism can be clarified and partially resolved by careful consideration of the ‘grain’ at which evolutionary
processes are described. The framework of ‘adaptive landscapes’ can be used to illustrate and facilitate this investigation.
We argue that natural selection may have special status at an intermediate grain of analysis of evolutionary processes. The
cases of sickle-cell disease and genomic imprinting are used as case studies.

It’s recently been argued that biological fitness can’t change over the course of an organism’s life as a result of organisms’
behaviors. However, some characterizations of biological function and biological altruism tacitly or explicitly assume that
an effect of a trait can change an organism’s fitness. In the first part of the paper, I explain that the core idea of changing
fitness can be understood in terms of conditional probabilities defined over sequences of events in an organism’s life. The
result is a notion of “conditional fitness” which is static but which captures intuitions about apparent behavioral effects
on fitness. The second part of the paper investigates the possibility of providing a systematic foundation for conditional
fitness in terms of spaces of sequences of states of an organism and its environment. I argue that the resulting “organism–environment
history conception” helps unify diverse biological perspectives, and may provide part of a metaphysics of natural selection.

This paper examines the relation between public land management policy, amenity migration, and socioeconomic well-being using
the case of the Northwest Forest Plan—a forest management policy that caused 11.6 million acres of federal land in the US
Pacific Northwest to be reallocated from commodity production to biodiversity services. Our analysis focuses on three propositions
implicit in much of the amenity migration literature in the USA: land management policies that reduce commodity production
and/or increase environmental protection (1) improve the natural amenity values of public lands; (2) increase amenity migration
to communities near public lands; and (3) stimulate economic development and increase socioeconomic well-being in these communities.
Our findings indicate that all three propositions are problematic and demonstrate the importance of community-scale analysis
for understanding the relation between land management policies, amenity migration, and community well-being. We discuss the
implications of our findings for public land management and rural community development.

Anthropologists and psychiatrists traditionally have used the salience of a mind–body dichotomy to distinguish Western from
non-Western ethnopsychologies. However, despite claims of mind–body holism in non-Western cultures, mind–body divisions are
prominent in non-Western groups. In this article, we discuss three issues: the ethnopsychology of mind–body dichotomies in
Nepal, the relationship between mind–body dichotomies and the hierarchy of resort in a medical pluralistic context, and, finally,
the role of mind–body dichotomies in public health interventions (biomedical and psychosocial) aimed toward decreasing the
stigmatization of mental illness. We assert that, by understanding mind–body relations in non-Western settings, their implications,
and ways in which to reconstitute these relations in a less stigmatizing manner, medical anthropologists and mental health
workers can contribute to the reduction of stigma in global mental health care.

Studies on the effects of a variety of exogenous and anthropogenic environmental factors, including endocrine disruptors,
heavy metals, UV light, high temperature, and others, on marine organisms have been presented at the 2nd Bilateral Seminar
Italy–Japan held in November 2006. Reports were discussed in order to reveal the current situation of marine ecosystems, aiming
at evaluation and prediction of environmental risks.

Jablonka and Lamb's claim that evolutionary biology is undergoing a ‘revolution’ is queried. But the very concept of revolutionary
change has uncertain application to a field organized in the manner of contemporary biology. The explanatory primacy of sequence
properties is also discussed.

Skunkworks in the Embers of the Cedar Fire: Enhancing Resilience in the Aftermath of Disaster 总被引:2,自引:0,他引:2
Bruce Evan Goldstein 《Human ecology: an interdisciplinary journal》2008,36(1):15-28
A coalition of environmental activists and professionals created the San Diego Fire Recovery Network (SDFRN) while the largest
wildfire in California history was still burning at the city’s edge in October 2003. Acting quickly while the citizenry questioned
governmental ability to protect their rapidly growing region, SDFRN proposed to reduce fire risk in a way that altered residential
knowledge practices and identity while reshaping governance relationships. While this effort stalled after governmental agencies
restored public confidence through massive fire prevention initiatives, SDFRN’s efforts may not have been in vain. Retained
within collective memory, SDFRN contributed to community resilience by diversifying possible responses to environmental change
and uncertainty. In this way, flexible, informal learning organizations such as SDFRN may serve as “skunkworks,” seizing on
disaster in order to incubate social–ecological relationships that might avert greater tragedies to come.

The results of an analysis of the viewpoints of Celestún community members regarding the Ría Celestún Biosphere Reserve, Mexico,
are used as the basis for recommendation to improve the community/natural protected area (NPA) relationship. Participant observation
was used to record the opinions of 80 people (8–83 years of age) between April and August 2002. Twenty semistructured interviews
were held with local young people randomly selected from the participant observation group and their fathers; one interview
was held with a municipal officer. Results indicate that the informants perceived a lack of communication between community
members and the Reserve concerning its objectives and action areas, minimal community participation in Reserve regulation
development, an absence of alternative productive activities and unjustified restriction of natural resources. These perceived
conditions can potentially generate conflict between the community and the Reserve administration, preventing fulfillment
of the Reserve’s environmental protection mission and negatively affecting community welfare. It is suggested that communication
between the Reserve and the community be mutual and free-flowing, that Reserve objectives be identified in conjunction with
the community, that community members be included in Reserve activities and administration, that interdisciplinary teams be
formed to encourage communication and participation and that alternative productive activities be developed. Particular emphasis
is placed on the need to listen to and address the concerns of young people because they will define the community/Reserve
relationship in the near future.

This paper examines people’s experiences with economic compensation for losses due to human–wildlife conflict (HWC) in Uttarakhand,
India. Employing a combination of qualitative and quantitative approaches, we used a case study approach to investigate (1)
socio-economic characteristics of applicant versus non-applicant households, (2) explanations for why only some households
chose to apply, and (3) perceptions of program effectiveness. We found that despite widespread complaints, the participation
rate was only 37%. Our results broadly support the findings of other studies which have identified inadequate remuneration,
processing delays, and corruption as key problems. However, we also found that non-participation was itself a critical problem.
Our study indicates that participation in the scheme was shaped by factors including wealth, gender, social networks, and
pre-existing expectations. We highlight the need for improved communication about what “compensation” can and should be, advocate
for reconceptualizations of compensation that are more closely based on ground-level realities, and point to the potential
for alternative forms of payment to be more sustainable and socially just.

In Limahuli Stream on the Hawaiian island of Kauai, species assemblage structure was monitored from catchment-to-sea over
a 6-year period to determine how individual species utilized the stream continuum spatiotemporally. A persistent pattern was
identified in which ten fish and macroinvertebrate species (nine native and one alien) were distributed into distinct zones
of highest abundances with overlapping species ranges. Species diversity, as quantified by a dominance measure (Berger–Parker
Index), was highest and least variable at the midpoint of the continuum where upstream–downstream species’ ranges converged.
Reciprocal fluctuations in the population abundances of dominant species limited overall variation in species diversity to
a 22% range which was interpreted as evidence of spatiotemporal persistence of the species assemblage structure. The pattern
was captured in a testable, conceptual model which partitions an idealized Hawaiian stream from catchment-to-sea into five
functional zones (Estuarine, Lower–Middle–Upper Reach, and Headwaters) positioned as percentages of continuum length. This
model may be overlaid upon other Hawaiian streams for testing its applicability as well as to ask a variety of ecological
questions about the manner in which species partition habitat spatiotemporally along biophysical gradients.

In 1998, a decree issued by the Indonesian government enabled communities in Krui, Indonesia, to register for concession rights
over the area of state forest land planted with their agroforests. Registration would provide farmers with the legal right
to manage and benefit from these agroforests. In 2005, we found that even though none of the Krui communities has ever formally
applied for their concession rights, the decree has been instrumental in stopping outsiders’ attempts to appropriate these
agroforests. Farmers within the state forest zone felt secure enough to continue investing in their complex agroforestry systems,
while planting trees reinforced their feeling of security. We conclude that it is not the legal status of tenure, but the
perception of tenure security that is of significance in people’s land-use decisions. These results are considered in the
wider context of state–community conflicts over forest land in the tropics.

Cerebral palsy has been associated with a number of candidate genes. To date, no systematic review has been conducted to synthesise
genetic polymorphism associations with cerebral palsy. We apply the HuGE NET guidelines to search PubMed and EMBASE databases
for publications investigating single nucleotide polymorphisms (SNPs) and cerebral palsy outcome. 22 papers were identified
and are discussed in this review. Candidate genes were grouped as (1) thrombophilic, (2) cytokine, (3) apolipoprotein E or
(4) other SNPs, largely related to cardiovascular physiology/pathophysiology and the functioning of the immune system. Of
the studies identified, cohorts were usually small, without adequate control and ethnically diverse, making direct comparison
between studies difficult. The most promising candidate genes include factor V Leiden, methylenetetrahydrofolate reductase,
lymphotoxin-α, tumour necrosis factor-α, eNOS and mannose binding lectin. Large case–control studies are needed to confirm
these candidates with attention given to cohort ethnicity, cerebral palsy subtype analysis and possible multiple gene and
gene–environment interactions.

This paper focuses on evolution as a unifying theme in biology education. Our aim is to argue that the different topics taught
in secondary school biology classes should be enriched with and linked together by means of accounts of the history of life.
We named this approach a “natural history perspective” on biology education. An essential aspect of the natural history perspective
is the claim that evolutionary history forms the context for the development of an understanding of evolutionary processes.
While there are some indications that a natural history perspective can function as a context for understanding micro-evolutionary
processes, more research is called for.

The paper introduces a novel computational approach to brain dynamics modeling that integrates dynamic gene–protein regulatory
networks with a neural network model. Interaction of genes and proteins in neurons affects the dynamics of the whole neural
network. Through tuning the gene–protein interaction network and the initial gene/protein expression values, different states
of the neural network dynamics can be achieved. A generic computational neurogenetic model is introduced that implements this
approach. It is illustrated by means of a simple neurogenetic model of a spiking neural network of the generation of local
field potential. Our approach allows for investigation of how deleted or mutated genes can alter the dynamics of a model neural
network. We conclude with the proposal how to extend this approach to model cognitive neurodynamics.
