There have been a number of different assessments of the significance of existentialism within psychotherapy in general and in relationship to psychoanalysis in particular. It has been suggested that ...existential analysis was primarly a vehicle for the introduction of religious consolation into therapy, an attempt to use the phenomenological method to buttress faith by appeal to “experience as given” against reductive reason. Freud thought so, and gently chided Binswanger for his illusions. Boss was militant in his defense of the “numinous” quality of religious experience. A number of his case studies described a therapeutic progression from the liberation of sensuous
The Comet Nucleus Tour (CONTOUR) is a low-cost NASA Discovery mission designed to conduct three close flybys of comet nuclei. Selected configuration tradeoffs conducted to balance science ...requirements with low mission cost are reviewed. The tradeoffs discussed focus on the optical instruments and related spacecraft considerations. Two instruments are under development. The CONTOUR Forward Imager (CFI) is designed to perform optical navigation, moderate resolution nucleus/jet imaging, and imaging of faint molecular emission bands in the coma. The CONTOUR Remote Imager and Spectrometer (CRISP) is designed to obtain high-resolution multispectral images of the nucleus, conduct spectral mapping of the nucleus surface, and provide a backup optical navigation capability.
Tradeoffs discussed are: (1) the impact on the optical instruments of not using reaction wheels on the spacecraft, (2) the improved performance and simplification gained by implementing a dedicated star tracker instead of including this function in CFI, (3) the improved flexibility and robustness of switching to a low frame rate tracker for CRISP, (4) the improved performance and simplification of replacing a visible imaging spectrometer by enhanced multispectral imaging in CRISP, and (5) the impact on spacecraft resources of these and other tradeoffs.
The purpose of the Astrobiological MIP Sensor (AMS) Project is to develop reliable, low-cost, low-mass, low-power consumption detection technologies for
in situ analysis of biochemical markers, and ...other indicators of astrobiological importance. To this end, we are investigating the potential role that molecularly imprinted polymers (MIP) could serve in the recognition of pre-biotic and biotic compounds in planetary, astrobiological and geochemical mission profiles. While MIPs are effective molecular recognition tools, a signal transduction method must be developed so that the recognition of analytes can be realized. In the course of this study, surface plasmon resonance (SPR) will be the detection method of the MIP recognition event. In addition, MIP-coated SPR substrates were subjected to vibration, temperature and radiation testing to demonstrate that they could withstand the rigors of space travel. The methods developed in this study require capture of the biomarkers onto the SPR sensor chip, followed by addition of a MIP. It is the binding of the MIP to the SPR bound analyte that amplifies the SPR signal associated with binding of the low molecular weight analyte. The MIPs, developed in this study are water-soluble processable star polymers while the SPR device used was SensíQ™ by Nomatics. Proof-of-principal experiments were first demonstrated using amino biotin.

The history of resurfacing by tectonism and volcanism on Venus is reconstructed by means of an analysis of Venusian impact crater size-frequency distributions, locations, and preservation states. An ...atmospheric transit model for meteoroids demonstrates that for craters larger than about 30 km, the size-frequency distribution is close to the atmosphere-free case. An age of cessation of rapid resurfacing of about 500 Ma is obtained. It is inferred that a range of surface ages are recorded by the impact crater population; e.g., the Aphrodite zone is relatively young. An end-member model is developed to quantify resurfacing scenarios. It is argued that Venus has been resurfacing at an average rate of about 1 sq km/yr. Numerical simulations of resurfacing showed that there are two solution branches that satisfy the completely spatially random location restraint for Venusian craters: a is less than 0.0003 (4 deg diameter circle) and a is greater than 0.1 (74 deg diameter circle).
In this study, we evaluated the effects of viewing an educational videotape about pediatric anesthesia on measures of parental knowledge of anesthesia and preoperative anxiety using a randomized, ...controlled design.During their routine preoperative visit, 85 parents of children scheduled to undergo ambulatory surgical procedures under general anesthesia were randomized to view either the experimental videotape about pediatric anesthesia or a control videotape with no medical content. Before and immediately after viewing the assigned videotape, parents completed measures of situational anxiety (State-Trait Anxiety Inventory-State), preoperative anxiety and need for information (Amsterdam Preoperative Anxiety and Information Scale), and anesthesia knowledge (Standard Anesthesia Learning Test). Repeated-measures analyses of variance showed that parents who viewed the experimental videotape showed a significant increase in anesthesia knowledge (P < 0.022) and a significant reduction in their state of anxiety (P < 0.031), anesthesia-specific anxiety, and need for information (P < 0.0001) compared with the control group. These results demonstrated that viewing a preoperative educational videotape about pediatric anesthesia can provide immediate educational and anxiolytic benefits for parents of children undergoing ambulatory surgery. The duration of these benefits remains to be determined. ImplicationsIn this study, we demonstrated the benefits of viewing an educational videotape about pediatric anesthesia on measures of parental knowledge of anesthesia and preoperative anxiety using a randomized, controlled design. We found that videotape viewing facilitated preoperative preparation and lessened preoperative anxiety.(Anesth Analg 1999;88:246-50)
Studying major writers and philosophers--Schlegel and Schleiermacher in Germany, Wordsworth in England, and Chateaubriand in France--Gerald Izenberg shows how a combination of political, social, and ...psychological developments resulted in the modern concept of selfhood. More than a study of one national culture influencing another, this work goes to the heart of kindred intellectual processes in three European countries. Izenberg makes two persuasive and related arguments. The first is that the Romantics developed a new idea of the self as characterized by fundamentally opposing impulses: a drive to assert the authority of the self and expand that authority to absorb the universe, and the contradictory impulse to surrender to a greater idealized entity as the condition of the self's infinity. The second argument seeks to explain these paradoxes historically, showing how romantic individuality emerged as a compromise. Izenberg demonstrates how the Romantics retreated, in part, from a preliminary, radically activist ideal of autonomy they had worked out under the impact of the French Revolution. They had begun by seeing the individual self as the sole source of meaning and authority, but the convergence of crises in their personal lives with the crises of the revolution revealed this ideal as dangerously aggressive and self-aggrandizing. In reaction, the Romantics shifted their absolute claims for the self to the realm of creativity and imagination, and made such claims less dangerous by attributing totality to nature, art, lover, or state, which in return gave that totality back to the self.
— High signal‐to‐noise near‐infrared spectrometer (NIS) spectra acquired during the low phase flyby of the near‐Earth asteroid rendezvous (NEAR) mission to 433 Eros are analyzed to determine mineral ...chemistry and proportions of mafic silicates across the asteroid's surface at 2.68 × 5.50 km spatial resolution. Spectral band parameters are derived, and compared with those of laboratory samples of known mineral composition, grain size distribution and terrestrial, meteoritic and lunar pyroxene spectral properties. The NIS derived band parameters are consistent with ordinary chondrite meteorites. We invoke the presence of a clinopyroxene component in the spectra, which is consistent with ordinary chondrite mineralogy and/or some degree of partial melting of ordinary chondritic material. Spectra measured across the surface of Eros can reveal small but real spectral variations. Most relative spectra are uniform to within 1–2%. Some areas suggest compositional variations of a few percent. Spectral slope variations of a few percent are seen indicating a non‐uniform distribution of materials affecting the slope parameter but with no resolved absorption bands. We find no correlation of slope with viewing geometry or compositional variation. The band parameter values do not consistently indicate a specific ordinary chondrite class but Eros is definitely undifferentiated with possible compositional variations of no more than 1–2%.
