The nature of the distinction between primary and secondary processes, as described by Freud, has relevancy for both a cognitive psycholoy and a psychology of motivation. Several issues arising from an examination of the 2 processes are examined. Possible empirical approaches to the basic problems are presented.

This paper assembles literature data, mainly vapor pressures and concentration-cell electromotive forces (emf's), from which
the variation of activity of NaF and A1F3 when a third substance is added to Na3AlF6 can be deduced. The necessary theory is derived. Where there is more than one source of information on a given substance,
the agreement is poor, showing imprecision in the experimental data. Substances are characterized by ∂ In aAlF
3/∂N3, whereN

is the molar fraction of the additive, and a value of -1 is neutral, since it corresponds to a dilution effect. Positive
values show acids; A1F3 itself has a value of +27.9, while NaF has a value of -27.9. BeF2 and MgF2 are strong acids with values of +11, CaF2 is a weak acid with a value of +2, and LiF, SrF2, BaF2, and 1/3(A12O3) are weak bases with values of -2 to -3. 相似文献

To investigate the pathogenesis of acute Mycoplasma pneumoniae infection, BALB/c mice were anesthetized with metofane, and M. pneumoniae was introduced intranasally on days 0, 1, and 2. Mice were sacrificed on days 0-15. A histopathologic scoring system defined inflammatory changes in the lungs on a scale of 0-26 (least to most severe). Broth cultures were positive for all nasal passage and bronchoalveolar lavage (BAL) specimens. Histopathologic scores ranged from 0 to 21. The mean log10 (cfu/mL) were 4.1-6.4 on days 1-10 and >/=1.7 on days 13-15 for nasal passage and BAL specimens. Serum polymerase chain reaction was negative. ELISA for serum IgM and immunoblots for M. pneumoniae antibody were positive in 21 (62%) of 34 and 33 (97%) of 34 infected animals, respectively, at days 8-15. ELISA for IgG antibody was negative. This mouse pneumonia model can be used to study the immunologic and therapeutic responses to acute M. pneumoniae infection. 相似文献

As a consequence of exploration for hydrocarbons, and of research programs conducted by academic and international institutions, substantial progress has been made in recent years in definition of hydrocarbon bearing basins, and those potentially so, in Southeast Asia and the South China Sea. Basins and depositional provinces now recognized include: the Thai Basin, the Malay Basin, West Natuna and Penyu Basins, Saigon (Ho Chi Minh) and Mekong (Vung Tau) Basins, East Natuna area, the Greater Sarawak Basin including Central Luconia and Balingian depositional provinces, the Baram Delta/Brunei-Sabah Basin and the Northwest Palawan Shelf. Where hydrocarbons have been encountered, the deposits are commonly associated with rocks of mid- and Upper Miocene age. Oligocene and Pliocene occurrences are locally significant.With some exceptions, most sedimentary basin-fill was deposited within continental to coastal environments. Such sediments are commonly gas-prone. Where oil-prone, there are suggestions that the oil has been generated under conditions of greater thermal maturity. Stratigraphic correlation depends largely on recognition of cyclic successions by means of integration of information derived from seismic stratigraphy, and paleontological and environmental analysis. Structures are commonly anticlinal and fault-associated; the anticlines are commonly suspected to have diapiric cores. Major transcurrent faults of regional extent may have been instrumental in formation of depositional provinces and anticlinal trends. 相似文献

In this paper the concept of recursive Allen temporal algebra is fully described, along with its relationship to the smart scheduler program and the concept of smart scheduling in general. Flexible manufacturing systems (FMS) are described, and their relationship with smart scheduling is explored. A case study that shows the utility of SSP in an FMS environment is presented in detail. Conclusions about the concept of smart scheduling are presented in closing. 相似文献

Describes the testing of an active-alert induction procedure which sufficiently controlled conditions to permit a comparison between the alterations produced by that procedure and those produced by the traditional relaxation induction technique. Ss were 50 university students. In the active-alert induction the S rode a bicycle ergometer under load, keeping eyes open while exercising and receiving suggestions of alertness. The alternate form, used in random alternation with the same Ss, consisted of the standard eye-fixation and relaxation induction of the Stanford Hypnotic Susceptibility Scale, Form B (SHSS-B). Within each session on 2 days during which each S served, the induction procedure was followed by 8 tests of responses to suggestion, from the SHSS-A and SHSS-B. The mean measured hypnotic responsiveness was independent of the type of induction. The active-alert condition was characterized by an acceleration of the rate of pedaling for the more responsive Ss. Although the subjective alterations differed between the 2 kinds of induction, the highly susceptible reported that in both cases altered states were achieved.

Responds to the paper by T. A. Cleary et al (see record 1976-03505-001) on the use of standardized tests with minorities and notes substantial shortcomings in the article. These include (1) lack of response to the key arguments of many critics of extant testing, (2) lack of recommendations for improving test development, and (3) placement of blame for bad testing on the practitioner.

Methods of revealing grain size in a two-phase α-β titanium alloy have been examined and observations on beta grain growth
in the presence of alpha have been carried out. The technique proposed by Greenfield and Margolin1 for revealing β matrix grain sizes has been shown not to produce grain growth. However, for grain sizes of about 10 μm the
G.M. technique does not reveal all the grains because of the similarity in orientation in neighboring grains. These clusters
of similarly oriented grains are shown to persist as grain growth takes place but the misorientation between grains within
a cluster decreases. Both the beta grain growth and alpha particle coarsening follow the same time dependency from which it
is shown that a linear relationship exists between α particle size and β grain size. It is proposed that α particles must
dissolve from theβ grain edges for β grain growth to occur. The linear dependency between beta grain size,D
β, and alpha particle size,d
α, can be rationalized either on the basis of geometrical or surface tension considerations.
