    Notes: Studies in the early seventies suggested that the traditional work ethic position was changing and that the American worker was expressing new needs for interesting and challenging work. Current management practices in many companies are attempting to meet these new needs of workers for interesting jobs through a movement called human resource development. This suggests the need for research into the beliefs that inform this movement. The following study based on a sample of 366 managers shows that they have an orientation to work based on humanistic beliefs rather than the traditional work ethic position. Thus the new management style exemplified in the HRD movement may not simply be a push for increased performance, but may also be supported by a set of beliefs regarding the nature of work that is consistent with this style. This new orientation, however, does not include any positive beliefs relative to worker participation in decision-making. The latter is rejected very strongly by all the managers surveyed.

    Notes: Abstract We study the set of local fields φ describing the dynamics of a scalar, massless particle. It turns out that these fields are relatively local to the free, massless, scalar fieldA if the massless particle does not interact. This leads to a simple algebraic characterisation of interacting fields in the above framework.

    Description / Table of Contents: Summary Part II. On exposure to vibration the electrical muscular activity of the dorsal extensor increases (ECG-potentials eliminated) when the body-posture is strictly controlled. The higher vibration intensity 11 leads to a greater increase of the activity than the lower 12. The intensity dependence is particularly marked in the range 4 Hz. On exposure at 2 Hz the increase of the muscular activity is smaller than at 4 Hz or 8 Hz. No difference in the muscular response to sinusoidal and stochastic vibration can be shown by means of the mean muscular voltage. The muscular response under exposure to vibration is regarded as a reflex reaction which can produce an active vibration damping with exposure-dependent effectivity. The regulation of the body posture, characterized by the standard deviation (s) of the amplitude-histogram of stabilograms, shows a dependence on the vibration frequency immediately after exposure. After exposure to 2 Hz vibration there is (in contrast to 4 Hz and 8 Hz) a marked increase of s in the sagittal stabilogram, which is interpreted as a symptom of a latent kinetosis. Under the conditions studied it can be said that sinusoidal and stochastic vibrations do not affect the standard deviation differently. The galvanic vestibular excitability is recorded quantitatively as mean body-sway response (b.s.r.). After stochastic vibration the b.s.r. is less marked than after sinusoidal vibration. 15 minutes after the end of the stochastic vibration with the intensity I1 the b.s.r. is still smaller than after exposure to sinusoidal vibration of the same intensity. These results are discussed in relation to a different effect on the otolithes, which is dependent on the mode of vibration.
    Abstract: Summary Part III. Psychically regulated performances are investigated by means of the optical clock-test and an acoustical signal-detection during az-vibrations (2 Hz − 2.4 and 1.2 m/s2; 4 Hz − 1.7 and 2.4 m/s2; 8 Hz − 1.7 and 3.4 m/s2). Already when the “fatigue-decreased proficiency boundary” of ISO 2631 is not exceeded, significant performance-worsenings cannot be excluded. When this intensity is exceeded, marked performance-worsenings are observed. The results indicate that the frequencies 2 Hz and 4 Hz produce a stronger performance-worsening than a vibration of 8 Hz; statistically ensured differences can, however, not be shown. Sinusoidal and stochastic vibrations of the same r.m.s. do not differ with respect to their effects on psychically regulated performance; their subjective assessment is, however, different. From the results described in parts I, II, and III we conclude that: 1. the investigated sinusoidal and stochastic vibrations have nearly the same biological effects; there are some indications of more marked effects of stochastic vibration; 2. the “fatigue-decreased proficiency boundary” of ISO 2631 for the physical conditions investigated is minimum requirement for guaranteeing the entire proficiency; 2. for the frequency 2 Hz a stronger biological effect can be assumed than that fixed at present in ISO 2631. The hypothesis is discussed that a more pronounced effect of stochastic vibration, compared with sinusoidal vibration, can occur with increasing intensity and/or exposure time.
    Notes: Summary Part I. Investigations with sinusoidal and stochastic octave-band-wide az-vibration with the frequencies or mid-band frequencies 2, 4, and 8 Hz, respectively, and the same r.m.s. of the vibration acceleration for both modes of vibration and a 30-minute exposure are reported. In order to assess the effect, measurements of the transmission, vibration-related changes of the electromyogram of the dorsal muscles, the regulation of the body-posture (stabilography), the vestibular galvanic excitability, and psychically regulated performances were used. With a controlled unrestrained body-posture the transmission is lower at the intensities 11 (2 Hz − 2.4 m/s2; 4 Hz − 1.7 m/s2; 8 Hz − 1.7 m/s2) than at the intensities 12 (2 Hz − 1.2 m/s2; 4 Hz − 0.85 m/s2; 8 Hz − 0.85 m/s2). With the resonance frequency 4 Hz this non-linearity is particularly marked. A systematic difference between sinusoidal and stochastic vibration is not observed with regard to the transmission. Only stochastic vibration of 4 Hz − 0.85 m/s2 is more strongly damped than sinusoidal vibration of the same r.m.s.

    Description / Table of Contents: Zusammenfassung An in vitro perfundierten menschlichen Ovarien der Follikelreifungsphase wurden der intrafollikuläre, intraovarielle und arterielle hydrostatische Druck gemessen. Sowohl im Gefäßsystem, als intraovariell sind spontan auftretende Druckänderungen zu registrieren. Unter Adrenalin, Noradrenalin, Prostaglandin F2α und Oxytocin kommt es einmal zu einer zunehmenden Tonisierung des Gefäßsystems, zum anderen zu vermehrt auftretenden Spontankontraktionen, wobei vor allem unter Prostaglandin F2α und Catecholaminen eine Zunahme von Frequenz und Amplitude zu beobachten ist. Jede Druckerhöhung im ovariellen Gefäßsystem und Gewebe bewirkt in allen Follikeln, die sich noch nicht in der direkt präovulatorischen Phase befinden, ebenfalls einen Druckanstieg. Direkt präovulatorisch treten Druckerhöhungen im Follikel nicht mehr auf, die Volumenzunahme des Liquor folliculi geht dann mit einer zunehmenden Dehnbarkeit der Follikelwand parallel. Die Ergebnisse werden im Hinblick auf die biophysikalischen Aspekte der Ovulation besprochen.
    Notes: Summary The intrafollicular, intraovarian and intraarterial hydrostatic pressures were measured in vitro on human ovaries in the follicular ripening phase. It has been established that in the vascular system as well as in the intraovarian tissues pressure variations occur spontaneously. Thus for example under, the influence of epinephrine, norepinephrine, prostaglandine F2α and oxytocine, the tonicity of the vascular system increases and does so the number of spontaneous contractions rather noticeably, particularly under the influence of prostaglandine F2α, and under the various catecholamines an increase of frequency and amplitude has been observed. Any increase of pressure in the intraovarian vascular system and tissues will effect all the follicles not yet in the preovulatorian phase, in which they cause a similar pressure increase. However, follicles imminently preovulatorian have not shown such pressure increase because the increase of the “liquor folliculi” runs parallel to the increasing elasticity of the follicle walls. The findings are discussed in this article with a particular view of the biophysical aspects of ovulation.

    Notes: Summary The lamina ganglionaris of the superposition eye of Cloeon dipterum is composed of separate optic cartridges arranged in a hexagonal pattern. Each optic cartridge consists of one central, radially branched monopolar cell (Li) surrounded by a crown of seven retinula cell terminals and two more unilaterally branched monopolar cells (La1/La2) situated close together outside the cartridge. Projections to neighbouring cartridges have not been observed. In most cases, synaptic contacts could be seen between a presynaptic retinula cell and more than two other postsynaptic profiles, which belong to monopolar cells or sometimes to glial cells. Seven retinula cell fibers of one ommatidium pass in a bundle through the basement membrane, run into their respective cartridges without changing orientation and terminate at approximately equal levels in the lamina. Long visual fibers with endings in the medulla are not visible in the superposition eye lamina, but are present in the lateral apposition eye. The relationship between the behaviour of the animal, optic mechanisms of the superposition eye and the structure of the lamina is discussed.
