    The energetics of Colpidium campylum Stokes with a note on the vertical distribution of Ciliophera in the mud of Loch Leven, Kinross

    The energetics of, the holotrich ciliate Colpidium campylum fed on the bacterium Moraxella sp. at 10°C, 15°C and 20°C were investigated. The parameter used for ascertaining growth. was the volume of protoplasm produced measured by means of a Coulter Counter with a mean cell volume converter attachment. Growth and consumption were measured in relation to food availability as indicated by the ratio of bacteria: protozoan. Mean cell volume variation and reproduction were also measured in relation to food availability and energy consumed. Protozoan and bacterial material were harvested by centrifugation and freeze-dried for dried weight determinations and calorimetry studies. The energy content of Colpidium and its food source was determined with a Phillipson microbomb calorimeter. Respiration was measured in a Warburg respirometer. Oxygen uptake in relation to population density and cell size was considered as well as the production of information concerning the heat lost during respiration for incorporation into energy budgets. Energy budgets of. two types were constructed: a 24-hour energy budget for an individual and the life-span or generation energy budget for an individual. Gross growth efficiencies, net growth efficiencies and assimilation efficiencies were considered in detail. In addition to laboratory work the vertical distribution of Ciliophora in the mud of Loch Leven, Kinross, Scotland, was also considered; three sites, two shallow and one deep, being sampled with a core sampler over a 12 month period

Specifically, greater medial and posterior trochlear wedging, shallower trochleae and more obliquely oriented groove for the tendon of the flexor hallucis longus muscle on the talus, and a more anteriorly oriented posterior talar facet on the calcaneus, have been hypothesized to reflect a greater emphasis on vertical climbing in anthropoids. This research evaluated these features in extant anthropoids, and compared them between pairs of taxa representing different emphases on climbing in their locomotor repertoires. Although taxa vary in these features, they do not do so in predicted ways. Results suggest that these aspects of talocrural joint functional morphology are not associated with climbing in extant anthropoids, and cannot be used in isolation to predict behavior of fossil taxa. Although this research has evaluated only broad, pairwise contrasts between diverse groups of extant taxa, variation identified here provides justification for a more in depth, detailed analysis of talocrural functional morphology in anthropoids.Includes bibliographical references

    Investigating the use of behavioural, accelerometer and heart rate measurements to predict calving in dairy cows

    Get PDF
    Calving is an essential event in dairy production, as lactation only begins after calving and cows must give birth at regular intervals in order to maintain milk production. Careful management is important during the weeks around calving as this is when dairy cows most frequently experience health problems. Experienced stockmen use judgements based on physical and behavioural changes in order to recognise when cows may be about to calve, and subsequently be available to offer assistance when required. With increasing herd sizes and large numbers of cows per stockman, individual attention is often difficult. An automated system that monitors behavioural or physiological changes before calving could potentially be used to predict the time of calving, and help improve supervision by farm staff. Data comprising two years of records from Langhill Farm were used to identify any variables which could be used for calving prediction or as risk factors for various calving problems. Records kept by stockmen detailing the signs of calving and time of observation were compared with quantitative behavioural data. Observations from video recordings were used to identify any consistent behavioural changes occurring the day before calving that could be used to predict the onset of calving. The frequencies of lying and tail raises proved to be the most useful indicators, as they showed consistent changes in the final six hours before calving. Differences between heifers and cows, and between those experiencing calving difficulties and those which did not, were also investigated. Differences between heifers and cows were shown which should be taken into account when predicting calving times. However, no early-warning signs of difficulties were identified for cows and heifers assisted with a calving jack. Cows were also fitted with collars containing accelerometers to investigate if features in tri-axial accelerometer data could be shown to correspond to specific behaviours. Some success was achieved in identifying eating behaviour and postural changes, demonstrating that there is potential for monitoring behaviour using this method. Weekly heart rate recordings were also taken to establish if there was a change in the heart rate or heart rate variability during the final six weeks of gestation. Changes were found but, although they were statistically significant, they were considered too subtle for any practical application. Consistent changes in behaviour were observed in the six hours before calving, some of which could be measured using accelerometers. These changes have the potential to be used as the basis of an automated monitoring system to predict calving

    Justice and the good life : an analysis and defense of a communicative theory of ethics

    Thesis (Ph. D.)--Boston University, 1990.The central question of this dissertation 1s whether Habermas's discourse ethics can successfully take account of the kinds of criticisms of Kantian formalism, first raised by Hegel, without at the same time abdicating the universalism of the Kantian conception of justice. Specifically, it considers whether the universality of moral principles can be maintained while recognizing the particularity of our experiences and values. This question is pursued in the context of a discussion raised by contemporary Anglo-American ethicists. Communitarians such as Michael Sandel and Alasdair MacIntyre argue that . our notions of the right and the good are derived from a notion of the good life which defines the character of any given community. This would seem to undercut the force of Habermas's quasi-deontological position, which asserts that norms are only legitimated by universally valid criteria. This dissertation maintains that Habermas's theory of moral character accounts for both our historical rootedness and our ability to adopt a universalistic standpoint from which to question and assess our culturally mediated beliefs. When Habermas's position is considered in light of the arguments of critics such as Carol Gilligan, Martha Nussbaum, and Larry Blum, who criticize neo-Kantian tendencies to characterize morality as moral argument and the consequent failure to develop concepts of moral character, moral perception, moral emotion, and moral judgment, it becomes clear that Habermas needs a general moral theory that extends to the private sphere. It is posssible to reformulate Habermas's ethical theory so that the distinction between norms and values issues from an ideally regulated discourse that at the same time defines the boundary between public and private. The gap between norms and values also can be bridged by incorporating the notion of symmetrical reciprocity as a meta-norm of discourse, which would ground both principles of justice and a notion of the good without privileging any historically specific vision of the good life

    Self-neglect: a case study and implications for clinical practice

    Get PDF
    Self-neglect is a worldwide and serious public health issue that can have serious adverse outcomes and is more common in older people. Cases can vary in presentation but typically present as poor self-care, poor care of the environment and service refusal. Community nurses frequently encounter self-neglect cases and health and social care professionals play a key role in the identification, management and prevention of self-neglect. Self-neglect cases can give rise to ethical, personal and professional challenges. The aim of this article is to create a greater understanding of the concept of self-neglect among community nurses
