    This paper surveys the development of various approaches to quality that are essentially learning-centred: &bull;In the Schools sector: a brief overview of the Victorian Quality in Schools project; &bull;In Higher Education: work in progress at two Australian universities (Victoria University of Technology and Swinburne Universities of Technology in Melbourne); and &bull;In Vocational Education and Training: work in progress in re-orienting the policy approach to Quality towards a more flexible and learning-centred model.This paper will argue that when looked at from the perspective of the individual learner, there is a strong case for student learning to be placed at the very heart of Quality Systems in all sectors of education, and also therefore in related sectoral Quality Assurance programs and processes. <br /

    There is increase in combined ingestion of alcoholic beverages and energy drinks, but studies on their combined effects on tissue oxidative enzymes are limited. Hence, the present study examined the changes in tissue oxidative enzymes (aldehyde oxidase, AO, EC 1.2.3.1; xanthine oxidase, XO, EC 1.17.3.2; sulphite oxidase, SO, EC 1.8.3.1; and monoamine oxidase, MO, EC 1.4.3.4) in the liver, kidney, heart, brain and testes of rats exposed to red bull energy drink and ethanol. Twenty eight Wistar rats (190±5g) were used for the study. The animals were divided into four groups. Group 1 which was fed with only grower’s mash and water served as control. In addition to the normal dietand water rats in Group 2 receivedRed bull energy drink (3.5ml/kg body weight), while those in Group 3 received Ethanol (1.25g/kg body weight) by intubation. Rats in Group 4 received bothred bull and ethanol as in Groups 2 and 3.Consumption of red bull significantly (P&lt;0.05) decreased liver AO activity as compared to control. The results showed that red bull, ethanol or their combination had variable effects on tissue oxidative enzymes as alteration was observed in the activity of the oxidative enzymes. The effect of a combination of red bull and ethanol was more pronounced in the liver MO, kidney AO, liver XO and liver SO than either red bull or ethanol alone. In conclusion the present study has shown that consumption of red bull, ethanol or their combination may alter the ability of tissue oxidative enzymes to metabolize zenobiotics.Keywords: Oxidative enzymes, Energy drinks, Alcohol, Red Bull, Ra

    Evaluating the Epidemiology and Management of Bovine Congestive Heart Failure

    Get PDF
    A form of congestive heart failure is increasingly reported as a cause of death in feedlot cattle located at moderate altitude (≤ 1524 m.). Significant knowledge gaps exist in the epidemiology and management of this form of bovine congestive heart failure (BCHF) regarding frequency and timing of BCHF cases and ways in which beef cattle producers and veterinarians can mitigate this condition. These knowledge gaps present major barriers to understanding the mechanism of BCHF and mitigating the consequences of BCHF. The purpose of this thesis is to summarize current knowledge about BCHF, define gaps in knowledge for which more research is needed, formulate hypotheses regarding the knowledge gaps, and discuss two studies designed to test those hypotheses related to the emergence of BCHF. The first study presented is designed to estimate the frequency and timing of BCHF case development. The second study was completed to evaluate the effect of moving two bulls affected by pulmonary arterial hypertension from their ranch of origin to lower elevation as a possible management strategy for mitigation of pulmonary arterial hypertension. Results presented in this thesis provide evidence that the frequency of BCHF cases has increased over the course of six years in the feedlot studied and changing the environment of animals affected by pulmonary arterial hypertension by moving them to lower altitude can lead to a decrease in pulmonary arterial pressure. This thesis will interpret the results of both studies to highlight how these data can aid in understanding the underlying mechanism of BCHF. Advisor: Brian L. Vander Le

    Dam Mitigation: Collaboration or Confrontation? Take Your Pick: Clark Fork Projects Hydro Relicensing

    In the United States, privately owned hydroelectric facilities operate under fifty year licenses issued and administered by the Federal Energy Regulatory Commission (FERC). The usual process of license renewal involves consternation, confrontation, and litigation, resulting in delayed environmental mitigation and damaged professional relationships. Faced with the upcoming relicensing of two large hydroelectric facilities in the year 2001, Avista Corporation (formally Washington Water Power Company) knew that there had to be a better way. In February of 1999, Avista Corporation filed a renewal application culminating seven years of environmental studies and consultation with state and federal agencies, tribes, local government, landowners, and special interest groups. The heart of the application is the Clark Fork Settlement Agreement, representing consensus among 27 parties on all environmental and operational issues. The Settlement Agreement, based on the principles of adaptive management, provides for greater local control, allows for early implementation of natural resource enhancements (March 1999), provides for the management of dynamic resources through the new term of the license, and establishes long term, collaborative working relationships. This Clark Fork collaborative is nationally recognized as a model for FERC’s recently adopted alternative approach to relicensing. A better way. Bull trout (Salvelinus confluentus) recovery is a key issue in the relicensing of the Clark Fork projects. Listed as threatened under the Endangered Species Act, bull trout are the subject of a comprehensive restoration plan developed by the collaborative participants. Avista Corp. funding of fisheries programs in northern Idaho and northwestern Montana will benefit all native salmonids, but with a particular emphasis on bull trout

    Objective To investigate the mitigating effects of administration of local or systemic meloxicam on the electroencephalographic (EEG) and cardiovascular responses during surgical castration of Bos indicus bull calves. Study design Prospective, randomized, experimental study. Animals Thirty-six 6–8 month-old Bos indicus bull calves, with a mean ± standard deviation weight of 237 ± 19 kg. Methods Animals were randomly allocated to three groups of 12 (group L, 260 mg of 2% lidocaine subcutaneously and intratesticularly 5 minutes prior to castration; group M, 0.5 mg kg−1 of meloxicam subcutaneously 30 minutes prior to castration; group C, no pre-operative analgesia administered). Anaesthesia was induced and maintained with halothane (0.9–1.1%) in oxygen. Electroencephalogram, heart rate (HR) and mean blood pressure (MAP) were recorded for 300 seconds prior to (baseline, B) and from the start of surgery (first testicle incision, T1). HR and MAP were compared at 10 second intervals for 90 seconds from the start of T1. Median frequency (F50), spectral edge frequency (F95) and total power of the EEG (Ptot) were analysed using area under the curve comparing T1 to B. Results All EEG variables were significantly different between B and T1 (p ≤ 0.0001). No differences in F50 were found between groups during T1 (p = 0.6491). F95 and Ptot were significantly different between group L and groups C and M during T1 (p = 0.0005 and 0.0163, respectively). There were transient significant changes in HR and MAP in groups L and M compared to group C during the 20–50 second periods. Conclusions The EEG changes indicate nociceptive responses in all three groups during surgical castration, greater in group L compared to groups C and M. Both analgesics attenuated the peracute cardiovascular response. Lidocaine and meloxicam administered prior to castration attenuated these responses in Bos indicus bull calves. Clinical relevance These findings provide support for the pre-operative administration of lidocaine and potentially meloxicam for castration in Bos indicus bull calves

    The bovine dilated cardiomyopathy locus maps to a 1.0-Mb interval on chromosome 18

    Cardiomyopathies are myocardial diseases that lead to cardiac dysfunction, heart failure, arrhythmia, and sudden death. In human medicine, cardiomyopathies frequently warrant heart transplantation in children and adults. Bovine dilated cardiomyopathy (BDCMP) is a heart muscle disorder that has been observed during the last 30years in cattle of Holstein-Friesian origin. In Switzerland BDCMP affects Swiss Fleckvieh and Red Holstein breeds. BDCMP is characterized by a cardiac enlargement with ventricular remodeling and chamber dilatation. The common symptoms in affected animals are subacute subcutaneous edema, congestion of the jugular veins, and tachycardia with gallop rhythm. A cardiomegaly with dilatation and hypertrophy of all heart chambers, myocardial degeneration, and fibrosis are typical postmortem findings. It was shown that all BDCMP cases reported worldwide traced back to a red factor-carrying Holstein-Friesian bull, ABC Reflection Sovereign. An autosomal recessive mode of inheritance was proposed for BDCMP. Recently, the disease locus was mapped to a 6.7-Mb interval MSBDCMP06-BMS2785 on bovine Chr 18 (BTA18). In the present study the BDCMP locus was fine mapped by using a combined strategy of homozygosity mapping and association study. A BAC contig of 2.9Mb encompassing the crucial interval was constructed to establish the correct marker order on BTA18. We show that the disease locus is located in a gene-rich interval of 1.0Mb and is flanked by the microsatellite markers DIK3006 and MSBDCMP5
