Record dynamics in ants (2010)
Journal Article

The success of social animals (including ourselves) can be attributed to efficiencies that arise from a division of labour. Many animal societies have a communal nest which certain individuals must leave to perform external tasks, for example foragin... Read More about Record dynamics in ants.

Emergency networking: famine relief in ant colonies (2010)
Journal Article

Resource distribution is fundamental to social organization, but it poses a dilemma. How to facilitate the spread of useful resources but restrict harmful substances? This dilemma reaches a zenith in famine relief. Survival depends on distributing fo... Read More about Emergency networking: famine relief in ant colonies.

Division of labour in ant colonies in terms of attractive fields (2009)
Journal Article

In nature there exist many mechanisms giving rise to self-regulation. One such mechanism is the division of labour in insect societies. Within this work we propose a mathematical model for the allocation of tasks in ant colonies, where each of the ta...

Symbionts of societies that fission: Mites as guests or parasites of army ants (2009)
Journal Article

Recently, Hughes et al. (Trends in Ecology & Evolution, 23, 672-677, 2008) have theorised that symbionts of large, long-lived, homeostatic, and well defended social insect colonies should mostly be of low virulence. If the symbionts are rare, i.e. fe... Read More about Symbionts of societies that fission: Mites as guests or parasites of army ants.

An alternative test to check the validity of convergence results (2009)
Journal Article

This article presents a simple method for identifying distributional dynamic properties of economies using the ideas of concordance and discordance. It can be employed to examine the strength and validity of the results of other methods. The method h... Read More about An alternative test to check the validity of convergence results.

Objective evidence for the use of polylactic acid implants in HIV-associated facial lipoatrophy using three-dimensional surface laser scanning and psychological assessment (2009)
Journal Article

The advent of highly active antiretroviral therapy (HAART) has dramatically improved the life expectancy of people infected with human immunodeficiency virus (HIV). Although patients often have excellent disease control with these combinations of ant...

A randomized clinical trial of a brief hypnosis intervention to control venepuncture-related pain of paediatric cancer patients (2009)
Journal Article

Venepuncture for blood sampling can be a distressing experience for a considerable number of children. A prospective controlled trial was conducted to compare the efficacy of a local anaesthetic (EMLA) with a combination of EMLA with self-hypnosis in...

Radio tagging reveals the roles of corpulence, experience and social information in ant decision making (2009)
Journal Article

Ant colonies are factories within fortresses (Oster and Wilson 1978). They run on resources foraged from an outside world fraught with danger. On what basis do individual ants decide to leave the safety of the nest? We investigated the relative roles...

The behaviour of ant transporters at the old and new nests during successive colony emigrations (2008)
Journal Article

Colonies of the ant Temnothorax albipennis improve their collective performance over successive emigrations (Langridge et al. Behav Ecol Sociobiol 56:523-529, 2004, Behav Ecol Sociobiol 62:447-456, 2008). Here, by analysing the performance of individ...

Can ant colonies choose a far-and-away better nest over an in-the-way poor one? (2008)
Journal Article

Nest choice in the ant Temnothorax albipennis is a model system for investigating collective decision making. Previous research has demonstrated the sophistication of this decentralized system, yet such studies have focused on binary choices in which...

Individual and collective choice: Parallel prospecting and mining in ants (2008)
Journal Article

Decision making is of crucial importance in the lives of both animals and humans. How decisions of group members scale up to group decisions is of great interest. Accordingly, we gave homeless ant colonies (n=67) in three experiments a choice between... Read More about Individual and collective choice: Parallel prospecting and mining in ants.

How experienced individuals contribute to an improvement in collective performance in ants (2008)
Journal Article

Certain groups of organisms are capable of improving their collective performance with experience. In a recent study, we demonstrated that, over successive emigrations, colonies of the ant Temnothorax albipennis are able to improve their collective p...

Parental pain expectancy as a mediator between child expected and experienced procedure-related pain intensity during painful medical procedures (2007)
Journal Article

OBJECTIVES: The aim of this prospective investigation was to evaluate child and parental expectancies as a predictor of pain perception in pediatric oncology patients undergoing painful medical procedures. METHODS: Forty-five children with leukemia o...

Convergence towards a steady-state distribution (2007)
Journal Article

The convergence literature frequently presupposes some unidentified steady-state distribution. This paper presents a new method to identify the presence and rate of convergence to a steady-state distribution. The method is illustrated with applicatio...

Bristol COPD knowledge questionnaire (BCKQ): Testing what we teach patients about COPD (2006)
Journal Article

Health professionals recommend education of patients about COPD. There is no satisfactory instrument to measure their knowledge and therefore to assess the results of education. A multiple-choice questionnaire (BCKQ) has been designed and tested. Eac... Read More about Bristol COPD knowledge questionnaire (BCKQ): Testing what we teach patients about COPD.
