Role diversity-operationalized by the number of relevant role senders-job level, subunit size, and company size are examined in this paper as determinants of perceived managerial satisfaction. Perceived need satisfaction, need fulfillment deficiency, need importance, and possibility of need fulfillment serve as the dependent variables. Role diversity and job level are found to be more significantly related to need satisfaction and possibility of need fulfillment than subunit or company size. Results are interpreted in the context of role theory and previous research by Porter. Administrative implications are suggested in the areas of reward system design and managerial motivation.

Ratios of emission line intensities are used to calculate the variation of temperature and the variation of electron density as a function of ion class for differing paths through a coronal enhancement. The data indicate (a) a peak mean electron density of 2.3 × 10 cm, (b) a temperature maximum greater than 2.3 × 10 K, and (c) the non-coincidence of the peak temperature and peak mean electron density. The latter demonstrates the invalidity of the assumption of symmetric models for coronal enhancements. The abundance of Ni was found to be equal to 0.045 that of Fe from the line ratio I(λ 6702)/ / I(λ 7059) and a density model based on the variation of the ratio I(λ 8024)/ I(λ 6702).

The diagnostic method developed in the two preceding papers of this series is applied to coronal forbidden line intensity data obtained at eclipses in 1952, 1961, 1965, 1966, and 1970. The application of the method is limited by the nature of the data but allows a first inference of the relationship between electron density and temperature in the condensations observed at these eclipses, and of the distribution of the electrons within the temperature range samples by the observations effectively 10 to 2.4 × 10 K. We determine the relative abundance of nickel to iron in the corona, finding a value in agreement with latest photospheric determinations and with a similar (factor of two) uncertainty. We are also able to set lower limits to the abundance of iron with respect to hydrogen, again finding values consistent with recent photospheric determinations. [ABSTRACT FROM AUTHOR]

A survey of the infrared coronal spectrum between 1 μ and 3 μ was made from a high altitude aircraft during the 7 March, 1970, solar eclipse. The observations were made with a Fourier transform spectrometer and were confined to the outer chromosphere and inner corona. In addition to well known chromospheric lines of H i and He i, nine additional lines were seen. Evidence is presented for the tentative assignment of these lines to forbidden transitions in highly ionized atoms of magnesium, aluminum, silicon, sulphur, and chromium. [ABSTRACT FROM AUTHOR]

Slit spectrograms of a quiescent prominence and the inner corona ( h⩽2.5 arc min) in the range λλ3400-7000 Å (dispersion 6-10 Å/mm) were obtained. From an analysis of the Stark effect on the Balmer lines (up to number 36) the electron density in the prominence n = (7 ± 3) × 10 cm was deduced. The kinetic temperature T and the non-thermal velocities υ, found from a simultaneous consideration of the Balmer and metal lines, are T ≈ 10 000 K and v≈6 km/s. Also the emission measure of the prominence along the line-of-sight was found: ME = 10 cm. In the coronal spectrum 24 coronal lines were found. Thirteen of these lines were identified and measured photometrically to get their absolute intensities, profiles and halfwidths. For nine lines the intensities as a function of the height were studied and on this basis the coronal lines were divided into a few groups. The line-of-sight and non-thermal velocities are υ ⩽ 10 km/s and υ≈ 25 km/s. The coronal lines originate in at least three types of regions with different temperatures. The emission measure as a function of the ionization temperature was determined. The abundances of four elements of the iron group (V, Cr, Mn, Co) were estimated. The abundances of the other elements of the same group (A, Ca, Fe, Ni), found from EUV-data, are in a good agreement with our observations. The degree of inhomogeneity in the corona was estimated: $$\overline {n_e^2 } /(\overline n _e )^2 \approx 3 - 10$$ . [ABSTRACT FROM AUTHOR]

On the slit spectrogram obtained at the 1970 eclipse in Mexico, the intensities of four coronal lines (Ni xiii λ5116, Fe xiv λ5303, Fe x λ6374, and Ni xv λ6702) and the continuum were measured as a function of distance along the slit. It is found that there exist a lot of fine fluctuations both in the lines and in the continuum intensities superposed on a large scale formation. The correspondence of such fluctuations between the continuum and the lines is good, with the exception of the line λ6374 which shows a peculiar fluctuation. It is shown that the intensities of the three lines λλ5116, 5303, and 6702 seem to be proportional to the square of the continuum intensity while the λ6374 line intensity may be proportional to the fourth power or more.

A series of spectrograms of the inner solar corona were obtained at the total solar eclipse of 30 May 1965 using a fast spectrograph with a circular slit that recorded the spectrum from λ3000 to λ9000 at all position angles around the limb simultaneously. In this paper absolute intensity is given as a function of position angle for the stronger lines and the continuum. In the coronal enhancement or condensation centered at heliocentric position angle 293°, absolute intensity is given for 34 forbidden emission lines and the continuum. [ABSTRACT FROM AUTHOR]

The excitation of the 2s2p ground configuration of Ca xv is calculated for coronal densities and temperatures. The calculations include electron and proton excitation of the forbidden transitions and electron excitation via the first excited (2s2p) configuration. It is shown that measurements of the line intensity ratio I(λ 5694)/ I(λ 5446) are in good agreement with the predictions. The line to continuum observations for limb flares and coronal condensations are discussed. It is suggested that the calcium abundance in condensations is enhanced owing to diffusion processes.

A literature search has been made pertaining to the identifications of coronal visible lines. Of over one hundred lines reported seen at eclipses, about forty identifications are widely quoted. Close scrutiny of the literature, however, reveals that only twenty of these identifications are not disputed by one or more authors. [ABSTRACT FROM AUTHOR]

Observations were made on the movement and distribution of zinc 65 and the distribution of stable zinc in water, sediments, and macrobiota of two estuarine ponds. Pond I was essentially a closed system and Pond II was connected to an adjoining estuary. In Pond I, zinc 65 moved rapidly from the water to other components of the ecosystem so that after 1 day only 66% of zinc 65 remained in the water. In Pond II, approximately 82% of zinc 65 was flushed out within 1 day by tidal exchange of water between the pond and the adjoining estuary; of the zinc 65 remaining, 36% was in bottom sediment, 59% in the water (one-third of the amount in the water was associated with suspended material), and 5% in the macrobiota. After 100 days, the bulk of zinc 65 and stable zinc was in the sediment of each pond. Analysis of specific activity (μμc zinc 65/μg zinc) in components of the ecosystem indicated that the exchange of zinc between sediment and water dominated the cycling of this element and controlled the distribution of zinc 65 in the ponds.

Flow velocity in the ascending aorta and aortic blood pressure were recorded continuously in healthy conscious dogs. Using implanted pneumatic cuffs the effect of bilateral carotid occlusion on heart rate, stroke volume, cardiac output, peak velocity, maximum acceleration, blood pressure, and total peripheral resistance (T.P.R.) was studied in the resting animal. Following carotid occlusion heart rate rose within 3-4 sec by 13 beats/min; during the steady state it exceeded the control by 8 beats/min. Cardiac output closely followed heart rate, since stroke volume decreased slightly (3-4%), mainly because of the elevated aortic pressure. During the first 3-4 sec cardiac output increased by 10-15% reaching a steady state level 8% above control. The initial fast increase of cardiac output caused mean aortic pressure to rise rapidly, while T.P.R. transiently decreased. Subsequently T.P.R. rose, causing a secondary slow increase of pressure. During the steady state blood pressure was elevated by 27 mm Hg (26%), T.P.R. by 12.1 mm Hg×l×min (20%). Maximum acceleration did not change with heart rate and was hardly affected (−1.5%) by the pressure rise. Peak velocity was little influenced by heart rate; it decreased by 7% mainly because of the elevated aortic pressure. β-blockade (0.5 mg/kg propranolol) affected T.P.R. only during control (+18%), but did not modify the time course of the reflex and its steady state changes. α-blockade (5.0 mg/kg phenoxybenzamine) decreased aortic mean pressure (5 mm Hg) and T.P.R. (7%) during control. Following carotid occlusion T.P.R. rose by the same amount, but much more slowly. Starting from the lower control the same pressure level was now obtained by a higher reflex increase of heart rate and cardiac output. It is concluded that the initial pressor response is initiated by an increase of cardiac output mediated by vagal inhibition. The secondary rise of blood pressure is predominantly caused by an increase of T.P.R. due to autoregulation in some vascular beds. The higher stroke work during the reflex is not accomplished by an increased contractility due to sympathetic activation. [ABSTRACT FROM AUTHOR]

A list of emission lines in the spectra of solar flares between 6 Å and 25 Å has been compiled using data obtained with a KAP crystal spectrometer on the OSO-5 satellite. The emission lines have been classified according to their sensitivity to flare activity. This classification provides a method for discriminating between iron in high stages of ionization (Fe xx-Fe xxv) and lower stages (Fe xvii- Fe xix), the lines of which are both present in the same spectral region during flares. Identifications consistent with these classifications are proposed. Anomalous intensities in the spectra of Fe xvii and Fe xx are pointed out, and implications of the observations for models of the X-ray emitting regions are discussed. [ABSTRACT FROM AUTHOR]

Groups of engineering apprentices were tested on the pursuit rotor under conditions of high and low drive, respectively, and with a 6 min. rest pause occurring after 3 and 8 min. massed practice, respectively; a post-rest practice period of 4 min. was given to all the groups. Reminiscence scores were obtained by subtracting scores on the last 10 sec. pre-rest trial from scores on the first 10 sec. post-rest trial. It was predicted that reminiscence scores would be higher for the high drive group than for the low drive group, and it was also predicted that this difference would be greater after 8 min. practice than after 3 min. practice. Differences were also predicted in level of performance, both pre-rest and post-rest. Predictions relating to reminiscence were verified at a high level of statistical significance; those relating to performance were in the predicted direction, but did not support the theory quite as clearly. A model of pursuit rotor performance was constructed on the basis of the data obtained in this experiment, as well as on previously obtained information, which permits quantitative predictions to be made.
