A new model of collaborative action research; theorising from inter-professional practice development

The development of pedagogies to meet the needs of diverse communities can be supported through inter-professional practice development. This article explores one such experience, that of speech and language therapists developing a new video-based coaching approach for teachers and teaching assistants in multi-cultural settings with high numbers of children learning English as an additional language. To support them in developing and trialling the coaching approach, the expertise of a teacher-educator and educational researcher was provided through a university business voucher. It is this working relationship that the article has as its practical focus, as it transformed to one of collaborative action research. The action research is described, providing the context for a discussion of the characteristics of collaborative action research and the proposal of a new model. This model offers a way of conceptualising collaborative action research through time, and of recognising the importance of the partners’ zones of proximal, contributory and collaborative activities in sustaining change and knowledge-creation

Patient and Public Involvement and Engagement for PhD Students

This paper aims to provide useful advice regarding the development of skills for patient and public involvement and engagement (PPIE) in research. The authors of this paper comprise experienced PhD supervisors and trainers, researchers leading PPIE activities including in the National Institute for Health and Social Care Research (NIHR) Nottingham Biomedical Research Centre (BRC), and experts in the conduct of PPIE. The paper arose from discussions in preparation for a programme of PPIE training for PhD students in the University of Nottingham, UK. We offer this advice on the basis that it is likely to be of use to others undertaking research training such as undergraduates or research associates moving into health-related research areas. Although the PPIE team of the NIHR Nottingham Biomedical Research Centre prepared this paper, we hope that it is of value across the whole spectrum of health research, not solely to experimental medicine and is of relevance to research more widely than that supported by the UK’s NIHR. The first section introduces PPIE, explains what it is and what it is not, and why it is important. The second section provides specific advice

The Role of Quantitative Pharmacology in an Academic Translational Research Environment

Translational research is generally described as the application of basic science discoveries to the treatment or prevention of disease or injury. Its value is usually determined based on the likelihood that exploratory or developmental research can yield effective therapies. While the pharmaceutical industry has evolved into a highly specialized sector engaged in translational research, the academic medical research community has similarly embraced this paradigm largely through the motivation of the National Institute of Health (NIH) via its Roadmap initiative. The Clinical and Translational Science Award (CTSA) has created opportunities for institutions which can provide the multidisciplinary environment required to engage such research. A key component of the CTSA and an element of both the NIH Roadmap and the FDA Critical Path is the bridging of bench and bedside science via quantitative pharmacologic relationships. The infrastructure of the University of Pennsylvania/Children’s Hospital of Philadelphia CTSA is highlighted relative to both research and educational objectives reliant upon quantitative pharmacology. A case study, NIH-sponsored research program exploring NK1r antagonism for the treatment NeuroAIDS is used to illustrate the application of quantitative pharmacology in a translational research paradigm

Senescence and Sexual Selection in a Pelagic Copepod

The ecology of senescence in marine zooplankton is not well known. Here we demonstrate senescence effects in the marine copepod Oithona davisae and show how sex and sexual selection accelerate the rate of ageing in the males. We show that adult mortality increases and male mating capacity and female fertility decrease with age and that the deterioration in reproductive performance is faster for males. Males have a limited mating capacity because they can fertilize < 2 females day−1 and their reproductive life span is 10 days on average. High female encounter rates in nature (>10 day−1), a rapid age-dependent decline in female fertility, and a high mortality cost of mating in males are conducive to the development of male choosiness. In our experiments males in fact show a preference for mating with young females that are 3 times more fertile than 30-day old females. We argue that this may lead to severe male-male competition for young virgin females and a trade-off that favours investment in mate finding over maintenance. In nature, mate finding leads to a further elevated mortality of males, because these swim rapidly in their search for attractive partners, further relaxing fitness benefits of maintenance investments. We show that females have a short reproductive period compared to their average longevity but virgin females stay fertile for most of their life. We interpret this as an adaptation to a shortage of males, because a long life increases the chance of fertilization and/or of finding a high quality partner. The very long post reproductive life that many females experience is thus a secondary effect of such an adaptation

Genomic Resources for Sea Lice: Analysis of ESTs and Mitochondrial Genomes

Sea lice are common parasites of both farmed and wild salmon. Salmon farming constitutes an important economic market in North America, South America, and Northern Europe. Infections with sea lice can result in significant production losses. A compilation of genomic information on different genera of sea lice is an important resource for understanding their biology as well as for the study of population genetics and control strategies. We report on over 150,000 expressed sequence tags (ESTs) from five different species (Pacific Lepeophtheirus salmonis (49,672 new ESTs in addition to 14,994 previously reported ESTs), Atlantic L. salmonis (57,349 ESTs), Caligus clemensi (14,821 ESTs), Caligus rogercresseyi (32,135 ESTs), and Lernaeocera branchialis (16,441 ESTs)). For each species, ESTs were assembled into complete or partial genes and annotated by comparisons to known proteins in public databases. In addition, whole mitochondrial (mt) genome sequences of C. clemensi (13,440 bp) and C. rogercresseyi (13,468 bp) were determined and compared to L. salmonis. Both nuclear and mtDNA genes show very high levels of sequence divergence between these ectoparastic copepods suggesting that the different species of sea lice have been in existence for 37–113 million years and that parasitic association with salmonids is also quite ancient. Our ESTs and mtDNA data provide a novel resource for the study of sea louse biology, population genetics, and control strategies. This genomic information provides the material basis for the development of a 38K sea louse microarray that can be used in conjunction with our existing 44K salmon microarray to study host–parasite interactions at the molecular level. This report represents the largest genomic resource for any copepod species to date
