A philosophical justification for the community of inquiry approach to moral education
Creators: name: Sprod, TJ
Publisher: name: University Of Tasmania
Year: 2023

description: Any society requires that its young be brought up both to live well themselves, and to assist and allow others in the society to live well. In a pluralistic and dynamic society, moral persons must be thoughtful; flexible or steadfast when morality requires it. Through moral education, schools help their students develop into moral persons. Given that living morally requires a complex mix of moral beliefs, judgements, dispositions and actions, no single pedagogy will be adequate to the task. This thesis considers one pedagogy - the Community of Inquiry - and develops a philosophical underpinning for its use in moral education. This justification will show that, under a particular characterization of morality and moral development, certain capacities essential to moral personhood are best developed through the classroom use of the community of inquiry. Humans come into the world with genetic predispositions which unfold in transformative interaction with the world: physical and - most importantly - social. Through these, the basis for morality and many other capacities are laid. Chief amongst these is the ability to reason. I argue for a broad based conception of reasonableness, which encompasses five aspects: critical, creative, committed, contextual and embodied. The development of reasoning in social interaction creates persons who can think for themselves through their connection to others. Autonomy is not a cutting off from connection, but an ability to operate competently within intersubjectivity. The teacher's role in cultivating reasonableness and autonomy can be elaborated through consideration of Habermas' theory of communicative action. I develop a notion of pedagogic action that amalgamates the goal directed strategic educational action of the teacher with the essentially communicative and discursive action through which it must be achieved. If education is to produce moral persons, we require an account of morality at which to aim. I consider the strengths of Aristotle's virtue ethics, and show that its account of moral development - through habituation - is more reflexive than is commonly thought. Yet, it lacks a detailed account of reflection, and I turn to Habermas' virtue ethics - flawed as a complete meta-ethical system - to provide this, and to inject a dynamic for moral progress. Finally, I argue that the Community of Inquiry, being a discursive pedagogy, develops the aspects of reasonableness, and builds communicative autonomy in students as they reflectively assess their moral habits and decide in community how to become the sort of person they want to be.

Diagnosis and Therapy of Renal Disease in Dairy Cattle
Creators: name: Divers, T. J.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1982

description: There are a large number of diseases that may primarily affect the kidneys of dairy cattle. 1 The majority of these cattle with renal disease will be first identified by the clinician because of gross abnormalities observed during the cow's urination, abnormal rectal examination findings involving the urinary system or clinical laboratory data suggestive of renal dysfunction. Except for renal toxicities which may involve multiple animals in a herd, the incidence of any o_ne particular renal disease is most likely to be sporadic in a bovine population. The sporadic incidence of many of these diseases may make the diagnostic, therapeutic and prognostic approaches more difficult than more familiar diseases of other systems. It is the intent of this presentation to provide a review and update on the causes, clinical signs, laboratory finding, methods of diagnosis, therapy and prognosis in cattle with renal disease.

Studies concerning the chemistry of rare earth elements in organic environments

Publisher: name: University of British Columbia
Year: 2010

description: The infrared and proton magnetic resonance spectra of a number of compounds containing sites of Lewis basicity change in the presence of selected cyclopentadienyllanthanides, R3Ln. These spectral changes indicate that the lanthanide derivatives can act as Lewis acids towards bases such as bridging and terminal carbonyl ligands, terminal nitrosyl ligands, appropriate transition metals and a carbon-carbon triple bond. Several solid adducts can be isolated and characterized. The preparation of the new compounds R2LnM(_5-Cp)(C0)3 [Ln = Dy, Ho, Er or Yb; M = Mo or W] is described, and evidence for the existence of isocarbonyl linkages in these complexes is presented. As a synthetic route to compounds containing apparent lanthanide-transition element bonds, the direct reaction of elemental metals with transition metal organometal1ics is studied. Finely divided lanthanide and other metals react with substrates such as Mn(C0)5Br, (3-C3H5)Fe(C0)3I, [(5-Cp)Mo(C0)3]2 and (5-Cp)Cr(C0)3HgCl in THF to yield extremely reactive, air- and moisture-sensitive solutions. Some of the chemistry of these solutions and other synthetic approaches to them are outlined. The versatility of these solutions as reactive intermediates during the preparation of organometallic compounds is described.

description: In Deutschland werden jährlich über sieben Millionen gebrauchte Matratzen entsorgt, die überwiegend verbrannt und nur zu einem Bruchteil recycelt werden. Dieser lineare Ansatz belastet die Ressourcen, erhöht die Emissionen und birgt Umweltrisiken. Um diesen Herausforderungen zu begegnen, kann die erweiterte Herstellerverantwortung (Extended Producer Responsibility, EPR) als Instrument zur Umsetzung einer Kreislaufwirtschaft dienen. In dieser Masterarbeit wird daher untersucht, wie ein EPR-System für Matratzen in Deutschland gestaltet sein sollte, um Kreisläufe effizient zu schließen. Gleichzeitig zielt diese Thesis darauf ab, die damit verbundenen Anforderungen und Herausforderungen bei der Umsetzung eines solchen Systems zu identifizieren. 
Zur Beantwortung der Forschungsfragen wurden mithilfe von Expert*innen-Interviews und einer umfassenden Literaturrecherche drei EPR-Modelle entwickelt und anhand von ausgewählten Kriterien bewertet. Die Ergebnisse der Bewertung ergaben, dass ein Modell präferiert werden sollte, in dem eine sogenannte Producer Responsibility Organisation (PRO) gebündelt die Verantwortung der Hersteller übernimmt. Ein solches System würde unter anderem eine angemessene Kontrolle ermöglichen und Anreize für Forschung und Entwicklung im Bereich der Recyclingtechnologien und des zirkulären Designs der Matratzen schaffen. Obwohl die Datenlage über Altmatratzen und deren Verwertung in Deutschland derzeit noch begrenzt sind und die hier präsentierten Ergebnisse von der gewählten Methodik abhängen, dient diese Masterarbeit als erste Grundlage für die weitere Entwicklung eines EPR-Systems für Matratzen in Deutschland.

description: We present observations and analysis of time-series spectroscopy and photometry of the pulsating subdwarf B star PG 1219+534 (KY UMa). Subdwarf B stars are blue horizontal branch stars which have shed most of their hydrogen envelopes. Pulsating subdwarf B stars allow a probe into this interesting phase of evolution. Low resolution spectra were obtained at the Nordic Optical Telescope and Kitt Peak National Observatory, and photometric observations were obtained at MDM and Baker observatories in 2006. We extracted radial velocity and equivalent width variations from several Balmer and He I lines in individual spectra. The pulsation frequencies were separated via phase binning to detect line-profile variations in Balmer and helium lines, which were subsequently matched to atmospheric models to infer effective temperature and gravity changes throughout the pulsation cycle. From the photometry we recovered the four previously observed frequencies and detected a new fifth frequency. From the spectra we directly measured radial velocity and equivalent width variations for the four main frequencies and from atmospheric models we successfully inferred temperature and gravity changes for these four frequencies. We compared amplitude ratios and phase differences of these quantities and searched for outliers which could be identified as high-degree modes. These are the first such measurements for a "normal" amplitude pulsating subdwarf B star, indicating that spectroscopic studies can benefit the majority of pulsating subdwarf B stars.

description: Astroseismology in eclipsing binaries with Delta ($δ$) Scuti components offers a powerful means to derive stellar parameters and probe internal structures. To enable accurate frequency analysis, binary characteristics must be disentangled from the observed light curves. This study utilizes the LC2015 light curve modeling method, followed by the DC2015 differential correction process, integrated into the Wilson-Devinney (WD) eclipsing binary modeling code. The analysis focuses on two $δ$ Scuti binary systems, KIC 8504570 and SX DRACONIS (Dra), using Kepler and TESS photometric data, supplemented by literature-derived initial stellar parameters. The DC2015 process employs the Levenberg-Marquardt algorithm to minimize the difference between observed and modeled light curves. The refined models provide highly accurate stellar parameters, including primary and secondary star temperatures ($T_{eff},1$ and $T_{eff},2$), mass ratio (q), and primary star luminosity (L1) with associated errors. For KIC 8504570: $T_{eff},1$ (7400.9 $\pm$ 1.6) K, $T_{eff},2$ (5450.0 $\pm$ 1.0) K, q (0.5208 $\pm$ 0.0002), and L1 (11.8043 $\pm$ 0.0006)$L_\odot$. For SX Dra: $T_{eff},1$ (7729.7 $\pm$ 1.1) K , $T_{eff},2$ (4927.5 $\pm$ 0.5) K, q (0.4772 $\pm$ 0.0006), and L1 (7.0474 $\pm$ 0.0015)$L_\odot$.

description: We report on the discovery of a planetary system with a close-in transiting hot Jupiter on a near circular orbit and a massive outer planet on a highly eccentric orbit. The inner planet, HAT-P-13b, transits the bright V=10.622 G4 dwarf star GSC 3416-00543 every P = 2.916260 \pm 0.000010 days, with transit epoch Tc = 2454779.92979 \pm 0.00038 (BJD) and duration 0.1345 \pm 0.0017 d. The outer planet, HAT-P-13c orbits the star with P2 = 428.5 \pm 3.0 days and nominal transit center (assuming zero impact parameter) of T2c = 2454870.4 \pm 1.8 (BJD) or time of periastron passage T2,peri= 2454890.05 \pm 0.48 (BJD). Transits of the outer planet have not been observed, and may not be present. The host star has a mass of 1.22 \pm ^0.05_0.10 Msun, radius of 1.56 \pm 0.08 Rsun, effective temperature 5653 \pm 90 K, and is rather metal rich with [Fe=H] = +0.41 \pm 0.08. The inner planetary companion has a mass of 0.853\pm ^0.029_-0.046MJup, and radius of 1.281 \pm 0.079 RJup yielding a mean density of 0.498\pm +0.103_-0.069 gcm^-3. The outer companion has m2 sini2 = 15.2 \pm 1.0 MJup, and orbits on a highly eccentric orbit of e2 = 0.691 \pm 0.018. While we have not detected significant transit timing variations of HAT-P-13b, due to gravitational and light-travel time effects, future observations will constrain the orbital inclination of HAT-P-13c, along with its mutual inclination to HAT-P-13b. The HAT-P-13 (b,c) double-planet system may prove extremely valuable for theoretical studies of the formation and dynamics of planetary systems.

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We discuss carefully the vertices which describe the dipole open strings and closed strings on a D-brane with magnetic flux on a torus. Translation invariance along closed cycles forces surprisingly closed string vertices written in open string formalism to acquire Chan-Paton like matrices. Moreover the one loop amplitudes have a single trace for the part of gauge group with the magnetic flux. These peculiarities are also required by consistency of the action of T-duality in the open string sector. In this way we can show to all orders in perturbation theory the equivalence of the T-dual open string theories, gravitational interactions included. We provide also a new and direct derivation of the bosonic boundary state in presence of constant magnetic and Kalb-Ramond background based on Sciuto-Della Selva-Saito vertex formalism.

description: Using the SEDs of the weak AGNs 35 LINERs presented in a companion paper, we assess whether photoionization by the weak AGN can power the emission-line luminosities measured through the large (few-arcsecond) apertures used in ground-based spectroscopic surveys. Spectra taken through such apertures are used to define LINERs as a class and constrain non-stellar photoionization models for LINERs. Therefore, our energy budget test is a self-consistency check of the idea that the observed emission lines are powered by an AGN. We determine the ionizing luminosities and photon rates by integrating the observed SEDs and by scaling a template SED. Even if all ionizing photons are absorbed by the line-emitting gas, more than half of our LINERs suffer from a deficit of ionizing photons. In 1/3 of LINERs the deficit is severe. If only 10% of the ionizing photons are absorbed by the gas, there is an ionizing photon deficit in 85% of LINERs. We disfavor the possibility that additional electromagnetic power, either obscured or emitted in the unobservable far-UV band, is available from the AGN. We consider other power sources such as mechanical heating by compact jets and photoionization by young or old stars. Photoionization by young stars may be important in a small fraction of cases. Mechanical heating provides enough power in most cases but it is not clear how this power is transferred to the emission-line gas. Photoionization by post-AGB stars is an important power source; it provides more ionizing photons that the AGN in more than half of the LINERs and enough ionizing photons to power the emission lines in 1/3 of the LINERs. It appears likely that the emission-line spectra of LINERs obtained from the ground include the sum of emission from different regions where different power sources dominate.

description: The purpose of this paper is to review some of the diagnostic methods used in physical examination of the thoracic cavity. The focus will be on auscultation since this is the most useful diagnostic procedure every veterinarian can perform. A number of diagnostic tools are available for use in evaluation of diseases of the thoracic cavity. The most important of these tools is the art of auscultation. Knowledge of the origin and mechanism of production of cardiac and lung sounds will allow the practitioner to accurately diagnose the majority of the diseases he sees in the field. A number of other diagnostic procedures such as radiography, aspiration, and percussion are then used to further define or confirm the tentative diagnosis made by auscultation.

Symmetries of Nonrelativistic Phase Space and the Structure of Quark-Lepton Generation

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: According to the Hamiltonian formalism, nonrelativistic phase space may be considered as an arena of physics, with momentum and position treated as independent variables. Invariance of x^2+p^2 constitutes then a natural generalization of ordinary rotational invariance. We consider Dirac-like linearization of this form, with position and momentum satisfying standard commutation relations. This leads to the identification of a quantum-level structure from which some phase space properties might emerge. Genuine rotations and reflections in phase space are tied to the existence of new quantum numbers, unrelated to ordinary 3D space. Their properties allow their identification with the internal quantum numbers characterising the structure of a single quark-lepton generation in the Standard Model. In particular, the algebraic structure of the Harari-Shupe preon model of fundamental particles is reproduced exactly and without invoking any subparticles. Analysis of the Clifford algebra of nonrelativistic phase space singles out an element which might be associated with the concept of lepton mass. This element is transformed into a corresponding element for a single coloured quark, leading to a generalization of the concept of mass and a different starting point for the discussion of quark unobservability.

It is further suggested that measurements of the voltage dependence of tunnel junction switching time in the presence of external easy axis magnetic fields can be used to determine the magnitude and voltage dependence of the field-like torque.

description: The purpose of this paper is to present a brief overview of the major infectious diseases that limit reproduction in dairy cattle. In addition, a more detailed discussion of 4 reproductive diseases causing much concern among dairymen and practitioners will be presented. These 4 reproductive diseases are leptospirosis, ureaplasma, mycoplasma, and chlamydia. Evidence was presented to show that L. hardjo does not lower conception rate. Evaluation of dairymen's records suggests that conception rate drops during the acute phase of urea plasma granular-vulvitis. Controlled trials using experimental inoculation of ureaplasma, mycoplasma, and chlamydia organisms at the time of breeding are needed to more clearly define the role of these organisms on conception rate.

description: Today many of us are apt to think of the dry period , as it relates to mastitis, as a time for effective therapy of the chronic infections present at drying off. Sometimes overlooked is the fact that the dry period is a time of high risk of new infections. Many of the intramammary infections (IMI) that will cause problems in the next lactation, especially the troublesome clinical cases so common just after calving, are due to infections established during the dry period. The emphasis of this presentation is on new infections during the dry period, and it will consider times of high susceptibility in the dry period, the types of infections most likely to occur, factors in susceptibility, dry period therapy as a prophylactic measure, and some management practices that may influence the new infection rate.

description: As part of international agreements, countries must report their greenhouse gas emissions. In associations of states such as the EU, it is desirable that the data used for reporting is also comparable. To date, there have been various methods for collecting data on forest soil, some of which differ so greatly from one another due to historically evolved circumstances that the data obtained cannot be harmonized. In addition, there are countries that have not yet collected any data, as a systematic survey, whether as part of an inventory or long-term monitoring, is time-consuming and cost-intensive. With this guideline, we therefore propose a basis that can be used in future to collect data for greenhouse gas (GHG) reporting in forest soils. The methodology is based on the ICP Forests manual and is limited to the parameters relevant for GHG reporting and their interpretation. It is possible to add individual parameters. With the help of the guideline, forest soil investigations can be linked to existing inventories (e.g. forest inventories) or the existing ICP Forests network can be consolidated with less complex sites.

description: Consider the Cauchy problem for a strictly hyperbolic, $N\times N$ quasilinear system in one space dimension $$ u_t+A(u) u_x=0,\qquad u(0,x)=\bar u(x), \eqno (1) $$ where $u \mapsto A(u)$ is a smooth matrix-valued map, and the initial data $\overline u$ is assumed to have small total variation. We investigate the rate of convergence of approximate solutions of (1) constructed by the Glimm scheme, under the assumption that, letting $λ_k(u)$, $r_k(u)$ denote the $k$-th eigenvalue and a corresponding eigenvector of $A(u)$, respectively, for each $k$-th characteristic family the linearly degenerate manifold $$ \mathcal{M}_k \doteq \big\{u\inΩ: \nablaλ_k(u)\cdot r_k(u)=0\big\} $$ is either the whole space, or it is empty, or it consists of a finite number of smooth, $N-1$-dimensional, connected, manifolds that are transversal to the characteristic vector field $r_k$. We introduce a Glimm type functional which is the sum of the cubic interaction potential defined in \cite{sie}, and of a quadratic term that takes into account interactions of waves of the same family with strength smaller than some fixed threshold parameter. Relying on an adapted wave tracing method, and on the decrease amount of such a functional, we obtain the same type of error estimates valid for Glimm approximate solutions of hyperbolic systems satisfying the classical Lax assumptions of genuine nonlinearity or linear degeneracy of the characteristic families.

description: Optimization of mixed categorical-continuous variables is prevalent in real-world applications of black-box optimization. Recently, CatCMA has been proposed as a method for optimizing such variables and has demonstrated success in hyper-parameter optimization problems. However, it encounters challenges when optimizing categorical variables in the presence of interaction between continuous and categorical variables in the objective function. In this paper, we focus on optimizing mixed binary-continuous variables as a special case and identify two types of variable interactions that make the problem particularly challenging for CatCMA. To address these difficulties, we propose two algorithmic components: a warm-starting strategy and a hyper-representation technique. We analyze their theoretical impact on test problems exhibiting these interaction properties. Empirical results demonstrate that the proposed components effectively address the identified challenges, and CatCMA enhanced with these components, named ICatCMA, outperforms the original CatCMA.

description: We prove using symplectic field theory that if the suspension of a hyperbolic diffeomorphism of the two-torus Lagrangian embeds in a closed uniruled symplectic six-manifold, then its image contains the boundary of a symplectic disc with vanishing Maslov index. This prevents such a Lagrangian submanifold to be monotone, for instance the real locus of a smooth real Fano manifold. It also prevents any Sol manifold to be in the real locus of an orientable real Del Pezzo fibration over a curve, confirming an expectation of J. Kollár. Finally, it constraints Hamiltonian diffeomorphisms of uniruled symplectic four-manifolds.

description: When cattle were confined, they were kept on dirt or on copius amounts of soft bedding. Under such conditions, the dairy farmer's chief complaint about the feet and legs of cattle was that their hooves did not wear properly. We would like to suggest that, while the floor surface must be considered, many other factors contribute significantly to foot and leg disorders and must not be neglected. Recommendations are based on our personal opinions formed from visiting a large number of dairy herds, reviewing the available literature, and many discussions with other researchers in the area.

Nutrition Management Programs for Dairy Herds
Creators: name: Nordlund, Ken
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1982

description: My concept of a dairy herd health program consisted of a well defined reproductive program, a somewhat confused vaccination program, and some rather vague ideas about rearing calves and controlling mastitis. That concept has changed. The best people in our profession have reshaped herd health into something much more capable of dealing with problems limiting dairy production. The emphasis has changed from health toward production with health.

description: We study the scattering of a weak and far-detuned light from a system of ultracold bosons in 1D and 3D optical lattices. We show the connection between angular distributions of the scattered light and statistical properties of a Bose gas in a periodic potential. The angular patterns are determined by the Fourier transform of the second-order correlation function, and thus they can be used to retrieve information on particle number fluctuations and correlations. We consider superfluid and Mott insulator phases of the Bose gas in a lattice, and we analyze in detail how the scattering depends on the system dimensionality, temperature and atom-atom interactions.

Subjects: subject: Cryptography and Security (cs.CR)

description: This paper proposes a visual encryption method to ensure the confidentiality of digital images. The model used is based on an autoencoder using aConvolutional Neural Network (CNN) to ensure the protection of the user data on both the sender side (encryption process) and the receiver side(decryption process)in a symmetric mode. To train and test the model, we used the MNIST and CIFAR-10 datasets. Our focus lies in generating an encrypted dataset by combining the original dataset with a random mask. Then, a convolutional autoencoder in the masked dataset will be designed and trained to learn essential image features in a reduced-dimensional latent space and reconstruct the image from this space. The used mask can be considered as a secret key known in standard cryptographic algorithms which allows the receiver of the masked data to recover the plain data. The implementation of this proposed encryption model demonstrates efficacy in preserving data confidentiality and integrity while reducing the dimensionality (for example we pass from 3072 Bytes to 1024 Bytes for CIFAR-10 images). Experimental results show that the used CNN exhibits a proficient encryption and decryption process on the MNIST dataset, and a proficient encryption and acceptable decryption process on the CIFAR-10 dataset.

Evaluation of factors affecting, and methods for extending, the shelf-life of packaged seafoods
Creators: name: Statham, Jo
Publisher: name: University Of Tasmania
Year: 2023

description: Vacuum packaging of fish results in minimal shelf-life extension due to the influence of the biochemical characteristics of fish muscle, such as the presence of trimethylamine oxide (an electron acceptor), low glycogen reserves and high ultimate pH. It is difficult to inhibit Gram negative spoilage bacteria without the addition of some form of preservative. Potassium sorbate effectively slowed microbial growth in scallops (Pecten fumata) when used in conjunction with vacuum packaging. Shelf-lives of 21-28 days at 4¬¨‚àûc were obtained. Inhibition of spoilage for extended periods and temperature abuse of sorbate treated scallops did not appear to increase the risk of spore germination and toxin production by Clostridium botulinum Types A, B, E and F. Toxin was produced by Type A at 27¬¨‚àûc, but only after the scallops had deteriorated beyond acceptability. No toxin was produced at 4¬¨‚àûc or 10¬¨‚àûc. The effect of K-sorbate on the shelf-life of blue grenadier (Macruronus novaezelandiae) fillets was less dramatic. Inconsistent results could be expected due to the variable properties of the fish flesh. pH is an important factor, as it affects the proportion of sorbic acid present in the undissociated state. Modified atmosphere storage (using 100% co2) at 4¬¨‚àûC resulted in a shelf-life of 16 days for trevalla (Hyperoglyphe porosa) and 22 days for scallops. The effect of co2 was to slow bacterial growth and select a flora dominated by lactic acid bacteria. A combination of potassium sorbate, polyphosphate and 100% co2 was more effective in extending the shelf-life of morwong (Nemadactylus macropterus) than either treatment alone, however the fillets dropped below borderline acceptability after 13 days. Inhibition of bacterial growth or the complete elimination of bacteria showed that the maximum shelf-life of seafoods is restricted by non-microbial factors. The shelf-life of sterile mullet and trumpeter stored at 4¬¨‚àûc was limited by nucleotide degradation and oxidation of fats, and was only marginally longer than for fish spoiling in the presence of bacteria. Antimicrobial activity of weak organic acids is considered to be pH dependent, the effect being reduced with increasing pH. However, potassium sorbate is inhibitory towards Alteromonas putrefaciens (an organism active in the spoilage of proteinaceous foods) at near neutral pH. Electron microscopy and cell lysis studies suggested that the site of action is the outer membrane of the cell.

description: Summary. In the present study, we examined a small sample of lophoproctids from the Balkan Peninsula and its surroundings. The millipede family Lophoproctidae is recorded from Serbia and Croatia for the first time, with Lophoproctus coecus Pocock, 1894 and Lophoproctinus (?) inferus (Silvestri, 1903) being involved, respectively. In addition, L. coecus is recorded for the first time from Bulgaria and the entire Balkan Peninsula. Finally, the genus Lophoproctinus Silvestri, 1948 is new to the Balkan fauna. Some remarks and the habitats of the new records are given, as well as taxonomic notes, variations in some specimens and a map with all records of the family in the Balkans and its surroundings.

A study of the relationship between discipline specific training and the images secondary teacher trainees hold of teaching
Creators: name: Nolan, Betty
Publisher: name: University Of Tasmania
Year: 2023

description: The central purpose of this study is to investigate whether or not the images which secondary teachers hold of teaching are partly determined by their subject discipline. A literature review suggests that there are four kinds of teacher images. These are images of the teacher as teacher, images of the curriculum, significant signposts, and discipline specific images. These various images overlap and are interdependent. In order to gauge how significant the differences in teacher images are between disciplines, final year secondary teacher trainees were asked to give their idea of \a really good teacher''. Using twenty characteristics of good teaching derived from Weinstein's (1989) research the trainees were asked to rank these qualities in order of importance. Responses were contrasted on the basis of discipline structure of training and gender. Results show that the images that secondary trainees hold of the good teacher do differ between disciplines. The differences are more marked when the students are studying a Diploma in Education course. Comparisons with a group of experienced Primary teachers indicate that those students in the final year of an integrated Bachelor of Education course are more child centred than Diploma of Education students in their view of good teaching. Gender does not appear to be a major factor in the images these trainees hold of the good teacher. This study adds to an understanding of image in three ways. It suggests that the way teachers think about teaching is a deeply entrenched way of thinking partly dependent on discipline specialisation. It proposes that a teacher's self image is dependent on a variety of macro and micro influences significant among which is discipline. Finally it suggests that these discipline specific images are generated by institutions in a largely implicit way. These institutions include schools as well as tertiary institutions. The study ends with recommendations for further research into _how a teacher's self teaching experience discipline and teacher training interrelate to produce teacher images."
A Review of Bovine Leukosis

description: Bovine leukosis was first recognized in Europe in the latter part of the 19th century. During the early l 900's, clinical reports of the disease continued to appear in the veterinary literature, not only in Europe but also in the United States. Veterinarians in Germany observed that many epidemiologic features of leukosis suggested it might be infectious, i.e., cases were clustered in certain herds and in limited geographic regions, and the disease was spreading from these herds or areas into previously leukosis-free cattle populations. The remainder of this paper will deal solely with the bovine leukemia virus (BL V), its characteristics, transmission, diagnosis, oncogenicity, and significance to the cattle industry of the United States.
