Models of pastoral counselling: An ethnographic study

This study, which seeks a model of pastoral counselling, examines twelve interviews of clergy and lay pastoral counsellors involved in counselling in a hospital, parish or social service agency. From the interviews the counsellors appear to have identified five themes. The first is the variety of psychological therapies and diagnostic tools upon which the counsellors draw. Secondly there is circumstance that organized a client-centred and flexible approach which describes the basic pattern and attitude the counsellors adopt. The third theme is the integration of psychology and theology in counselling. The fourth theme shows the counsellors exclusive use of scripture/theology during counselling. The metaphors, which the counsellors use to describe the pastoral counselling process is the fifth theme. The findings indicate the predominance of the first three themes in pastoral counselling models with theme four as an addition in specific instances. Theme five provides a descriptive guide to the models

THE EFFECT OF INLET GEOMETRY ON THE DEVELOPMENT OF A PLANE WALL JET

A turbulent wall jet, jet Reynolds number of 30 7000, issuing from a rectangular nozzle adjacent to a plane surface is experimentally examined for different thicknesses of the nozzle upper boundary and for different heights of the external co-flow above the jet. The object o f the study is to understand the role o f nozzle lip thickness and external stream height on the downstream development of the flow. Using cross hot-wire anemometry the velocity, shear stress and normal stress profiles of the flow were measured. The role of the external stream height is primarily to truncate the downstream distance for which a wall jet profile can be measured. No trend exists in the measurements due to increasing the lip thickness and it is postulated that the flow converts from a shear flow to a wake flow with increasing lip thickness

Achievement of cardiovascular risk factor targets in young adults with diabetes mellitus

Background: Many patients with diabetes mellitus fail to achieve treatment targets recommended in recognized guidelines. Little data is available in this area relating to young adults

Intraspecific variability modulates interspecific variability in animal organismal stoichiometry.

Interspecific differences in organismal stoichiometry (OS) have been documented in a wide range of animal taxa and are of significant interest for understanding evolutionary patterns in OS. In contrast, intraspecific variation in animal OS has generally been treated as analytical noise or random variation, even though available data suggest intraspecific variability in OS is widespread. Here, we assess how intraspecific variation in OS affects inferences about interspecific OS differences using two co-occurring Neotropical fishes: Poecilia reticulata and Rivulus hartii. A wide range of OS has been observed within both species and has been attributed to environmental differences among stream systems. We assess the contributions of species identity, stream system, and the interactions between stream and species to variability in N:P, C:P, and C:N. Because predation pressure can impact the foraging ecology and life-history traits of fishes, we compare predictors of OS between communities that include predators, and communities where predators are absent. We find that species identity is the strongest predictor of N:P, while stream or the interaction of stream and species contribute more to the overall variation in C:P and C:N. Interspecific differences in N:P, C:P, and C:N are therefore not consistent among streams. The relative contribution of stream or species to OS qualitatively changes between the two predation communities, but these differences do not have appreciable effects in interspecific patterns. We conclude that although species identity is a significant predictor of OS, intraspecific OS is sometimes sufficient to overwhelm or obfuscate interspecific differences in OS

When are fish sources versus sinks of nutrients in lake ecosystems?

Animals can be important in nutrient cycling through a variety of direct and indirect pathways. A high biomass of animals often represents a large pool of nutrients, leading some ecologists to argue that animal assemblages can represent nutrient sinks within ecosystems. The role of animals as sources vs. sinks of nutrients has been debated particularly extensively for freshwater fishes. We argue that a large pool size does not equate to a nutrient sink; rather, animals can be nutrient sinks when their biomass increases, when emigration rates are high, and/or when nutrients in animal carcasses are not remineralized. To further explore these ideas, we use a simple model to evaluate the conditions under which fish are phosphorus (P) sources or sinks at the ecosystem (lake) level, and at the habitat level (benthic and water column habitats). Our simulations suggest that, under most conditions, fish are sinks for benthic P but are net P sources to the water column. However, P source and sink strengths depend on fish feeding habits (proportion of P consumed from the benthos and water column), migration patterns, and especially the fate of carcass P. Of particular importance is the rate at which carcasses are mineralized and the relative importance of benthic vs. pelagic primary producers in taking up mineralized P (and excreted P). Higher proportional uptake of P by benthic primary producers increases the likelihood that fish are sinks for water column P. Carcass bones and scales are relatively recalcitrant and can represent a P sink even if fish biomass does not change over time. Thus, there is a need for better documentation of the fraction of carcass P that is remineralized, and the fate of this P, under natural conditions. We urge a more holistic perspective regarding the role of animals in nutrient cycling, with a focus on quantifying the rates at which animals consume, store, release, and transport nutrients under various conditions

Measuring the public health impact of vaccines: disease burden, vaccine coverage, safety and effectiveness

This thesis has eight chapters describing inter-relationships between work in 66 papers published between 1999 and 2020 relevant to the over-arching topic of public health impact of vaccines: measurement of disease burden, vaccine coverage, safety and effectiveness Chapter 1 outlines the key data sources used: 1. routinely collected administrative data (disease notifications, ICD coded hospitalisations and mortality data) and 2. additional data sources the author had a key role in developing (National Serosurveillance. Paediatric Active Enhanced Surveillance (PAEDS). In chapter 4, development of analysis and reporting of data from the Australian Immunisation Register and in chapter 6 development of platforms for vaccine safety evaluation are described. In Chapter 5, how this work culminated in pilot initiatives to link data sources relevant to public health impact of vaccines in a birth cohort from New South Wales and Western Australia, with the aim of demonstrating the potential for an all-age national capacity, is outlined. Chapter 2 focuses on disease due to Bordetella pertussis and research under the headings of measuring prevalence and severity of pertussis, the effectiveness and impact of pertussis vaccines and clinical trials conducted to evaluate the immunogenicity and safety of acellular pertussis vaccine given within 4 days of birth. Chapter 3 focuses on disease due to Streptococcus pneumoniae and research measuring pneumococcal disease, effectiveness and impact of pneumococcal vaccines and a randomised trial comparing immune responses to pneumococcal conjugate and polysaccharide vaccines in the frail elderly. Chapter 7 includes studies of vaccine impact against Hepatitis B, varicella, meningococcal C disease, mumps and Q fever and Chapter 8 includes four major international reviews of vaccine programs and impact
