Individual variability of behavioural responses by Wandering Albatrosses (Diomedea exulans) to human disturbance

Sub-Antarctic Marion Island has had a permanent research station for 50 years and the islands Wandering Albatrosses have been intensively studied for 20 years. The reactions of breeding birds to approaches by a human on foot were recorded. Three response variables were calculated: intensity of vocal reaction (IVR), intensity of non-vocal reaction (INR) and overall response index (ORI). At 5 m from the nest, twice as many birds stood and/or vocalised as at 15 m. Nearest neighbour distance, age and gender did not explain individual variability of responses. Study colony birds had higher IVR scores than non-study colony birds; birds at colonies closest to the station had the highest ORI scores. A better breeding record was associated with lower IVR and ORI scores, but a causative relationship remains to be demonstrated. A minimum viewing distance of 25 m is recommended for breeding Wandering Albatrosses.

Hennigian Phylogenetic Systematics and the ‘Groundplan’ vs. ‘Post-Groundplan’ Approaches: A Reply to Kukalová-Peck

The recent contribution by Jarmila Kukalová-Peck on Hennigian phylogenetics and hexapod limb evolution is critically evaluated.

Adaptationism and the adaptive landscape

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.

Negotiating Values: Narrative and Exposition

In this paper I focus on the limits of narrative by asking what kinds of things narratives do, and what kinds of texts do related things in other ways. In particular I focus on how narrative genres organise time in relation to value, drawing on functional linguistic models of temporality and evaluation. From a linguistic perspective, the various narrative genres negotiate different kinds of solidarity with listeners, and so the limits of narrative materialise various possibilities for communing in a culture, alongside the potentialities for construing community through related and other genres of discourse—since in general, the limits/possibilities of our language (and attendant modalities of communication) are the limits/possibilities of our social world.

Community Attachment: The Complexity and Consequence of the Natural Environment Facet

The primary objective of this paper is to examine more closely the complex nature of the natural environment dimension of community attachment using the narratives of local community members. This work seeks to build and elaborate on previous quantitative analyses that demonstrated two distinct dimensions of community attachment––social and natural environment. The findings reveal several distinct facets of the natural environment dimension of community attachment and demonstrate both a discreet perception of the natural environment in terms of community attachment as well as one that is more embedded within the social context of a particular lifestyle. The findings further demonstrate the need to include consideration of the natural environment in the broader assessment of community attachment and bolster previous quantitative research findings.

Heartache of the State,Enemy of the Self: Bipolar Disorder and Cultural Change in Urban China

Past works in anthropology and psychology have described the Chinese orientation toward life as situation-centered with an external locus of control. This model has also been applied to the understanding of affect disorders in China—depressive patients have been found to focus on outside circumstances surrounding dysphoric moods. However, dramatic economic, sociopolitical and cultural changes in post-Mao China may be affecting these cognitive orientations toward emotional distress. This paper focuses on the subjective experiences of individuals diagnosed with bipolar disorder in China. The study is based on semistructured interviews with patients at a Western-style mental health institution in Shenzhen, the first successful Special Economic Zone in China. My data suggest that the location of agency has shifted across generations. Whereas those who grew up in the Maoist era are inclined to use external circumstances to explain the control over and responsibility for their illness, younger patients tend to emphasize self-blame and individual responsibility. I argue that these intergenerational differences in ethnopsychology relate to the multifaceted rise of individualism in post-Mao China. The paper ends with an examination of this observed shift vis-à-vis recent theories of neoliberal discipline in China and a discussion of potential psychological implications.

Navigating Diagnoses: Understanding Mind–Body Relations, Mental Health, and Stigma in Nepal

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.

Grid user requirements—2004: a perspective from the trenches

Pervasive Grid adoption is predicated on the availability of widely deployed usable software and a user community willing to use it. Currently, widespread adoption of Grids, even within technically sophisticated communities, is limited, and determining and eliminating these barriers to adoption are essential in order for Grids to becoming widely capitalized. Through a series of face-to-face interviews conducted during the summer of 2004, we have identified issues relating to job submission, file transfer, usability, and systems management that must be resolved in order to improve the usability of Grid infrastructures. The background to these issues and some possible solutions are described in this paper.

Hierarchical analysis of piecewise affine models of gene regulatory networks

A key point in the analysis of dynamical models of biological systems is to handle systems of relatively high dimensions. In the present paper we propose a method to hierarchically organize a certain type of piecewise affine (PWA) differential systems. This specific class of systems has been extensively studied for the past few years, as it provides a good framework to model gene regulatory networks. The method, shown on several examples, allows a qualitative analysis of the asymptotic behavior of a PWA system, decomposing it into several smaller subsystems. This technique, based on the well-known strongly connected components decomposition, is not new. However, its adaptation to the non-smooth PWA differential equations turns out to be quite relevant because of the strong discrete structure underlying these equations. Its biological relevance is shown on a 7-dimensional PWA system modeling the gene network responsible for the carbon starvation response in Escherichia coli.

Allomaternal Care among the Hadza of Tanzania

Cooperative child care among humans, where individuals other than the biological mother (allomothers) provide care, may increase a mother’s fertility and the survivorship of her children. Although the potential benefits to the mother are clear, the motivations for allomothers to provide care are less clear. Here, we evaluate the kin selection allomothering hypothesis using observations on Hadza hunter-gatherers collected in ten camps over 17 months. Our results indicate that related allomothers spend the largest percentage of time holding children. The higher the degree of relatedness among kin, the more time they spend holding, supporting the hypothesis of nepotism as the strongest motivation for providing allomaternal care. Unrelated helpers of all ages also provide a substantial amount of investment, which may be motivated by learning to mother, reciprocity, or coercion.

Gridcast—a next generation broadcast infrastructure?

Gridcast is an R&D project investigating grid ideas and technologies in the broadcasting technical infrastructure. In this paper I discuss the business and technical issues in building infrastructures to support broadcasters and outline the structure of the Gridcast grid-based service oriented architecture for broadcasting playout support.

Is it a revolution?

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.

Causal Explanation of Indonesian Forest Fires: Concepts, Applications, and Research Priorities

Problems with studies, claims, and assumptions that have been made about the causes of fires in Indonesia's tropical moist forests are identified, and the kinds of concepts, methods, prioritizing, and data needed to resolve the problems are discussed. Separate sections are devoted to studying ignitions, studying fire susceptibility and fire behavior, and using the goal of causal explanation to guide interdisciplinary research.

From Orders to Borders: Toward a Sustainable Co-managed Lobster Fishery in Bonavista Bay, Newfoundland

Over the last two decades, demands by fish harvesters for greater input into policy-making, combined with government cutbacks to fisheries management agencies, have resulted in a proliferation of community-based fisheries comanagement projects in many countries. One such example is found on Newfoundland’s Eastport Peninsula, where a group of lobster harvesters have formed a unique partnership with federal government bureaucrats and university researchers in an effort to protect local lobster stocks from increasing fishing pressure. This paper draws upon interviews with lobster harvesters and others with close ties to the Eastport project in exploring the reasons for the development of this initiative and identifying existing and potential obstacles to its long-term success.

A simple and fast method for cell recovery and DNA content analysis from various mouse tissues by flow cytometry

Cell division in tissues can be investigated in various ways. We present here a method for improving cell recovery and cell cycle analysis for a wide range of mouse tissues. This strategy combines a cell isolation procedure for various mouse tissues based on intracardiac perfusion and subsequent treatment followed by flow cytometry. This easy and reproducible method allows a rapid analysis of nuclear DNA content, providing an estimate of the cell number at different phases of the cell cycle. This combined procedure could also be used for the isolation of specific cell subpopulations from different mouse tissues by fluorescence activated cell sorting.
