The ultrastructure of 4 species of the calcareous, siphonaceous alga Halimeda (H. cylindracea Decaisne, H. discoidea Decaisne, H. macroloba Decaisne and H. tuna (Ellis & Solander) Lamour) has been studied, and the observed changes during growth and development are related to changes in the degree of calcification. A distinct gradient in the types and quantities of cell organelles exists in a growing apical filament. As these filaments grow, branch, and eventually develop into a mature segment, changes in the organization of organelles such as mitochondria and chloroplasts are observed. Calcification begins when the chloroplasts reach structural maturity and when the peripheral utricles adhere (fuse). This adhesion of the peripheral utricles isolates the intercellular space (ICS) in which calcification occurs from the external seawater. Calcification begins in the outermost (pilose) cell wall layer of the walls facing into the ICS. The cell walls at the thallus exterior undergo extensive changes after utricular fusion; the pilose layer is lost, the cuticles of adjacent utricles fuse forming a ridge at their junction, and multiple cuticles are formed. The aragonite (CaCO3) crystals which are initially precipitated within the pilose wall layer, rapidly increase in size and number, eventually filling much of the ICS. Only the initial nucleation of aragonite is associated with the pilose wall layer, the later precipitation of aragonite is totally independent of the pilose layer. In older segments secondary deposition of CaCO3 also occurs around existing aragonite needles. Copyright © 1977, Wiley Blackwell. All rights reserved

The recent method of Serfling and Wackerly (1976) for constructing fixed-width confidence intervals for the center of location is extended to include M estimators. The resultant class of procedures is compared to the stopping times of Chow and Robbins (1965), as both the interval length d and intended noncoverage probability 2α converge to zero. Except in certain special cases, the stopping times are found to have different asymptotic distributions. The coverage probability of the Serfling-Wackerly class is found as d converges to zero. © 1977, Taylor & Francis Group, LLC.

The method of approximating a continuous distribution by a discrete distribution is used to approximate certain multidimensional ranking integrals. in the location and scale parameter cases the method results in a simple iterative counting algorithm. a bound on the error term is given. the algorithm is applied to the problem of completely ranking normal means and shown to be quite accurate and fast. applications of the above complete ranking problem are given, and the results are used to compute upper confidence bounds for mean differences in a trend situation. © 1977, Taylor & Francis Group, LLC.

Abstract— In cells of the red alga Griffithsia monilis the action spectrum of photosynthetic oxygen production at low light intensity shows that the phycobilins (including allophycocyanin) are the major light‐harvesting pigments. As the light intensity is increased carotenoids and chlorophyll a contribute proportionately more to the spectrum, since the phycobilin activity becomes light‐saturated. When action spectra are performed against a background light of various monochromatic wavelengths it can be shown that chlorophyll a increases in its light‐harvesting activity. Nevertheless light absorbed at a single wavelength (487 nm) by phycoerythrin (and possibly a carotenoid) still shows the highest photosynthetic activity. Fluorescence measurements at 77K indicate that a chlorophyll a fluorescence is small and that the amount of chlorophyll all (f 693) is very low. A model is proposed in which the phycobilins, in phycobilisomes, pass on absorbed light energy to either photosystem, whereas light absorbed by chlorophyll is passed on mainly to photosystem I.

The toilet training method described by Azrin and Foxx in Toilet Training in Less Than a Day was employed with five children whose mothers were supervised and five children whose mothers were not supervised. All children were between 20 and 26 months of age. Supervised mothers received pretreatment training as well as assistance during training, while nonsupervised mothers trained their children on the basis of their reading of the book. Training was more effective and the number of emotional side effects was less for both mothers and children in the supervised condition. © 1977 Association for Advancement of Behavior Therapy.

This study examined the differential effectiveness of muscular and cognitive relaxation as a function of locus of control. Eighteen internally oriented and 18 externally oriented females were randomly assigned to one or another of the relaxation conditions. As hypothesized, the cognitive relaxation procedure resulted in a greater decrement in heart rate and subjective distress for the internals, while muscular relaxation produced the greater decrement for the externals. Results underscored the utility of the client-treatment interactive model. © 1977.

The efficacy of two induced anxiety procedures on high and low trait-anxious individuals was investigated. Twenty-four males and 24 females were selected by A-Trait scores and randomly assigned to one of the two induced anxiety procedures or to a no-treatment control. Results indicated that the relax-induce-no relax-discuss variant of induced anxiety was superior to the standard procedure of relax-induce-relax-discuss. An extinction model of the effects of induced anxiety was proposed. © 1977 Association for Advancement of Behavior Therapy. All rights reserved.

Für sequentielle Rangauswahlprobleme, bei denen es sich um die Auswahl von m aus n (1 ≦ m ≦ n) sequentiell beobachtbaren Objekten ohne Rückgriffsmöglichkeit mit dem Ziel der Maximierung einer vorgegebenen Ertragsfunktion handelt, wird unter Voraussetzung einer bestehenden Rangfolge für die einzelnen Objekte die allgemeine Lösung angegeben. Davon ausgehend erfolgt die Lösung des speziellen Problems der Maximierung der Wahrscheinlichkeit für die Auswahl genau der m besten Objekte. Abschließend wird das asymptotische Verhalten der dabei gewonnenen optimalen Strategien bezüglich wachsender Objektanzahl n untersucht. Copyright © 1977 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
