Relative growth in some Antarctic Pycnogonida
Work on the systematics of a large collection of Antarctic Pycnogohida has revealed very forcibly the limitations of existing systems of classification of this group. In an attempt to rectify some of these shortcomings for a monograph on the pycnogonid fauna of the Ross Sea area, the author has been led to seek new characters and character states which will be useful in taxonomy.
Virtually nothing is known of pycnogonid behaviour and ecology, and it seems unlikely that additional knowledge in these fields will be forthcoming in the near future. Our knowledge of pycnogonid comparative anatomy and histology is also very slight. However, the Pycnogonida do lend themselves very readily to mensural description of much of their form. It is true that the expressions of some characters are more simply described by the traditional vocabulary of experts in the field (e.g., ovigeral spine shape), but for other characters this self-same vocabulary may be a source of confusion, as, for instance, in the description of proboscis shape.
A morphometric study involving: some 160 specimens of three species revealed that certain simple statistical hypotheses on relative growth can readily be proposed. The values to practical taxonomy and the possible functional interpretation of these hypotheses, in the light of existing information on pycnogonid anatomy, are discussed in the following pages.
The work was supported by National Science Foundation Grants Numbers G 14107, G 19338, and G 17890. Part of the work was carried out at the USARP Biology Laboratory at McMurdo Sound, Antarctica, and the author wishes to acknowledge his gratitude for the assistance and hospitality given to him by Dr. Donald E. Wohlschlag, the Director of the laboratory
Decision Support System for IPM in Potato/Tomato
A Decision Support System (DSS) for the management of potato and tomato late blight is being developed. A draft version is being evaluated by growers in New York. The DSS enables growers to access diverse tools in real time to improve their abilities to manage late blight with decreased fungicide. The tools are: i)ready access to site-specific observed weather; ii) ready access to farm-specific weather forecasts; iii) ready access to late blight disease forecasts; iv) models that enable growers to predict the effects of the various factors that influence late blight development. The goals of this project were to improve the components of the DSS and to make the DSS more user-friendly. The improvements accomplished during the funding period were focused on the user interface of the DSS. The front page was modified to clarify the effects of fungicide, and a risk alert was added. The risk-alert is designed to inform a user of the relative risk posed by late blight in proximity to the user. The algorithms for the risk-alert were calculated and the programming to include this in the DSS was completed. Evaluations of the risk-alert will occur in the future. The availability of the risk alert and the availability of the DSS are designed to eliminate the use of unnecessary (insurance) fungicide applications
Animals who think and love : law, identification and the moral psychology of guilt
How does the human animal who thinks and loves relate to criminal justice? This essay takes up the idea of a moral psychology of guilt promoted by Bernard Williams and Herbert Morris. Against modern liberal society’s ‘peculiar’ legal morality of voluntary responsibility (Williams), it pursues Morris’s ethical account of guilt as involving atonement and identification with others. Thinking of guilt in line with Morris, and linking it with the idea of moral psychology, takes the essay to Freud’s metapsychology in Civilization and Its Discontents. Two conflicting routes to guilt are noted in Freud, one involving internalisation of external anger to suppress destructive instincts, the other loving identification with others in the process of self-formation. This second route is developed through the psychoanalytic thought of Hans Loewald and Jonathan Lear. Following Loewald, the moral psychology of self-formation makes loving identification with others the root of responsibility, guilt and atonement. Following Lear, the moral psychology of guilt developed on these lines renders psychoanalysis part of a broadly understood philosophical project following Aristotelian and Socratic principles. Underlying Morris’s account of guilt is the possibility of ‘prospective identification’, understood as the moral and psychological ground of guilt and reconciliation. This is the rational core of criminal justice, which maintains an uneasy relationship with law’s ‘peculiar’ morality
General Taylor at Monterey
The steel engraving features an image of General Taylor mounted on horseback along with four other military officers (three on horseback). The group looks over a hillside at other soldiers in the distance. The image is engraved in black ink on white paper.https://scholarsjunction.msstate.edu/fvw-prints/1066/thumbnail.jp
