The Impact

The reproductive performance of tagged Weddell seals (Leptonychotes weddelli) was monitored at McMurdo Sound, Antarctica, from 1970 to 1984. An age-specific reproductive schedule revealed the major onset of pupping at age 6 years, and a mean age of first birth of 7.1 years. The average asymptotic pupping rate of 0.61 is reached by age 10. The cost of pupping in a given year is reflected in a 0.05 drop in the probability of pupping the following year. This cost is not evident in females over 7 years old, suggesting that postweaning condition affects newly mature females more than those that are fully mature. Annual adult reproductive rates ranged from 0.46 to 0.79, with a possible periodicity of 5 to 6 years. Simulations were conducted to determine the impact on reproductive estimates of sighting biases associated with seals having had at least one pup (Parous) or having pupped that season (With-Pup). Age at first reproduction as deduced from an age-specific pupping schedule is strongly affected by both forms of sighting bias, but bias in sighting Parous females was the more important. Estimates of adult reproduction were affected minimally. Comparisons of reproductive estimates with those of Weddell seals at Signy Island are discussed with regard to the effects of sighting biases.

Care Research

Abstract Patients and the public are involved in health and social care research more than ever before. Much effort has been put into developing patient and public involvement (PPI), and promoting co-production of research with patients and the public. Yet there is little guidance for researchers on how to involve PPI partners in the research process, or how involvement can be judged as meaningful. This presentation has its origins in the attempts of one research team to question and navigate a way of involving PPI in long term care research. In this presentation, we describe our model of collaborative qualitative data analysis with PPI partners, in a study exploring primary care services for older adults living in long-term care facilities in England. Anonymised interview transcript excerpts were presented in written, audio, and role-play format to our PPI partners. PPI partners derived meaning from interview data, identifying, confirming and critiquing emerging themes. Their input at this critical stage of the study deepened our initial analysis and prompted the research team to new and different interpretations of the data. This talk addresses ways of engaging PPI partners in innovative ways during data analysis, and offers other researchers some questions, challenges and potential principles for effective practice. We conclude that in areas such as long term care, with multiple stakeholders and a dynamic environment, effective PPI may be flexible, messy and difficult to define.

Abstract Twelve Lipid-Research Clinic laboratories performed automated cholesterol analyses on four control-serum pools of known cholesterol concentration, using the Liebermann-Burchard reaction. The analyses were done during a two-year period, with the same standards, methodology, and quality-control procedures. Estimates of analytical bias, variability, and short- and long-term trends for each instrument and for the entire group of LRC instruments are presented. High accuracy, precision, and interlaboratory comparability were achieved through the rigorous standardization and control of the entire analytical procedure. The significance of these results for long-term collaborative studies is discussed. Individual laboratory biases averaged from 0.5 to 2.0% below Abell-Kendall reference values. Between-run variability was about equal to within-run variability and inter-laboratory variation was substantially less than intra-laboratory variation. The total standard deviation for all instruments was about 0.04 g/liter. Only 8-15% of this variation was due to differences between instruments. The between-instrument standard deviation ranged from 0.011 to 0.015 g/liter; the between-run, within-instrument standard deviation ranged from 0.023 to 0.030 g/liter; and within-run standard deviation ranged from 0.023 to 0.028 g/liter. The significance of the achieved results for long-term collaborative studies is discussed.

The Brain

The IBSEN model of Imagination in Brain Systems for Episodes and Navigation explores how the architect’s experience is brought to bear in the design of architecture by building on the VISIONS model of understanding a visual scene and the TAM-WGM model of navigation. IBSEN develops the idea that a building provides both views from various viewpoints and places where particular experiences can be felt, and actions can be performed. For this, the design must support a variety of scripts for both practical and contemplative action and the cognitive maps that relate places for them. Nodes from different maps may be combined as scripts are harmonized with respect to a specific embedding of places in three-dimensional space. The chapter examines the role of the hippocampus in episodic memory and imagination, and observes that memory and imagination, episodic or not, are construction processes. During design, long-term working memory links internal and external memory systems, providing priority access to (but not only to) memory fragments that have proved relevant to the current design process. The designer in some sense “inverts” imagined experiences and behaviors of users of the forthcoming building. As the book ends, the author notes that we are only at the beginning of new collaborative studies that take cog/neuroscience out of the lab and into the building and the street.

And Control

Reference materials for water microbiology were prepared by spray-drying milk, artificially contaminated with a known test strain. The resulting highly contaminated milk powder was mixed with sterile milk powder to a contamination level of 2000-3000 cfu/g. Gelatin capsules were filled with the mixture (0.2 g/capsule) to produce the reference materials. Test strains used were: WR1 Escherichia coli, WR3 Enterobacter cloacae, WR63 Enterococcus faecium and WR51 Staphylococcus spec. Optimalization of the mixing procedure and aging of the highly contaminated milk powder resulted in relatively homogeneous and stable reference materials. Short-time challenge tests at “high” temperatures (30 and 37 °C) may be predictive for long-term stability at “low” temperatures (4-6 °C). Reference materials with strain WR3 were stable for one week at 30 °C and for at least 6 months at 4-6 °C. Possible applications of the reference materials are: quality control of routine measurements, comparison of the efficiency of different culturing methods and as a standardized sample in collaborative studies.
