Presents a dialog between an advocate of traditional psychoanalytic psychotherapy and a proponent of some newer therapeutic modalities: encounter groups, behavior modification, and primal (scream) therapy. The 2 speakers begin by agreeing on various important sources of mutual prejudice that might color their discussion. From their respective vantage points, they then raise issues concerning the nature of the relationship between patient and therapist; the techniques employed; the role of abreaction; the importance of diagnosis; and the place of thought and feeling, and of action and experience. They point out that their dialogue, at times, turns into a debate, and they end by agreeing on the need for integration of their different viewpoints.

Some statisticians contend that the experimentwise Type I error rate is the most important attribute of multiple comparison procedures to be used for making all possible pairwise comparisons among treatment means after an analysis of variance. That contention is challenged here. The importance of Type I errors is discussed as well as the occurrence of Type I errors in biological experiments. Also considered is the effect of Type I error protection on power. The two methods of measuring Type I error rate, comparisonwise and experimentwise, are explained, and the reader may decide which kind he wishes to control. Several references cited support Fisher's least significant difference and Duncan's new multiple range test despite their higher-than-nominal experimentwise Type I error rates. These procedures control the comparisonwise Type I error rates and are considerably more powerful in finding differences among treatments than procedures that control the experimentwise Type I error rates. 相似文献

The high-strength, high-modulus Kevlar 49 fiber is widely used today because of its superior properties. In this paper, we discuss the fundamental physicochemical nature of the commercial fiber. It is an extended chain polymer, poly(p-phenylene terephthalamide), which is highly crystalline. Extensive analysis shows that the material composition is quite consistent from lot to lot and is low in impurities. The fiber absorbs water reversibly; the extent of absorption is related to the ash content. The well-known interaction of the fiber with ultraviolet light is illustrated with spectra, and the thermal stability of the fiber is demonstrated with various thermal analysis techniques. 相似文献

A 200-foot pneumatically operated, portable plastic tower has been constructed to permit measurement of radiated signals and also to permit the radiation of r-f signals for overall susceptibility measurements. The electronic package contained at the top of the tower is semiautomated and is controlled from a console on the ground. Cable losses have been eliminated by locating all r-f circuitry at the antennas on top of the tower. This system was designed for making MIL-STD-449 type measurements on operational radars. The system, its operation and the data analysis methods will be discussed. 相似文献

The increase of Mn concentration and the simultaneous depletion of dissolved oxygen in the bottom waters (hypolimnion) of Lake Mendota, Wisconsin were studied in situ. Considerably higher Mn concentrations were found in the hypolimnion compared to Fe, despite a sedimentary Fe/Mn weight ratio of 19 : 1. Laboratory equilibration studies under anoxic conditions indicated that pH was an important parameter involved in the release of Mn from the sediments. This was also implied by the Mn and pH data measured in situ. Possible mechanisms involved in the release of Mn from the sediments including desorption of Mn from oxide substrates, reduction of Mn oxides and dissolution of carbonates and sulfides are discussed. 相似文献

The tracking resolution and vertex finding capabilities of the SLD experiment depend upon a precise knowledge of the location and orientation of the 96 elements of the SLD pixel vertex detector (VXD3) in 3D space. At the heart of the deterministic procedure described here to align the 96 CCDs is the matrix inversion technique of singular value decomposition (SVD). This tool is employed to unfold the detector geometry corrections from the track hit residual data in the VXD3. The algorithm is adapted to perform an optimal χ2 minimization by careful treatment of the errors and correlations in the residual measurements. The general form of the problems that might be solved with this technique is discussed. The tracking resolution obtained with the aligned geometry is compared with the starting point, based on an optical survey of the CCDs, and is shown to achieve the design performance. 相似文献

A simplified method for analysing the elastic stresses in geometrically imperfect cooling tower shells is outlined. The method is based on the replacement of the imperfection by an appropriate additional normal pressure. Illustrations with respect to both axi-symmetric and non axi-symmetric imperfections are presented and the validity of the method is established by comparisons with the direct analysis for the axi-symmetric case. Further simplifications are considered and a possible basis for codefied tolerances on meridional imperfections is developed. Some extensions to the method are suggested, particularly for the case of non axi-symmetric geometric imperfections. 相似文献

The perforatorium of rat spermatozoa was isolated and its protein composition determined. SDS-polyacrylamide gel electrophoresis showed that the organelle is composed of a single polypeptide component with a molecular weight of 13,000. The perforatorium becomes more resistant to solubilization during epididymal transit due to an apparent increase in disulphide bond content. Amino acid analysis of the perforatorium polypeptide revealed a content of 6-5% cysteine. 相似文献

Moderate (0.5–1.5 CIELAB units) color differences in surface colors were scaled visually to obtain color-dif-ference-perceptibility ellipses. The ellipse orientations appeared to be independent of the size of the color differences over the range indicated, and were consistent with literature results obtained with visual colorimeters. In the uivid greenish yellow region, the experimental ellipse orientation agreed with the Munsell spacing but not with the orientation of the CIELAB ellipse. In the deep greenish blue region, the experimental ellipse orientation agreed belter with the results of Wyszecki and Fielder than with the orientation of the MacAdam PGN ellipse. 相似文献

Full-scale room fire economics necessitate a screening test procedure requiring only a small amount of material to quantitatively
assess heat release rate. This test could determine which materials may justify full-scale testing and those which fail early.
Such a procedure is described, sample results are given, and it is suggested that correlation of screening test results with
full-room and bench-scale test methods could improve the evaluation of the pre-flashover fire spread characteristics of materials. 相似文献
