On the north side of Napatree Beach, short-term changes of the beach-face within the intertidal zone were studied to determine those processes most influential in causing change where nearshore processes are low in magnitude and beach changes are subtle. The data were subjected to multiple linear correlation and stepwise multiple-regression analyses. Tide level accounts for 41% of the explained variation for the relationship between the processes and beach height. Tide level is the only significant element effecting change in the beach profile. Wave height has no influence on changes in beach morphology. Significant results of beach energy associations have been obtained where low-amplitude nearshore processes are present even when beach changes are subtle. © 1975.

While land boundaries have occupied the attention of Israelis since 1948 and even earlier, they have been little concerned with the sea, and the legislation concerning their maritime boundaries is vague and incomplete. In addition, since the Six Day War Israel occupies territory with several different territorial seas, resulting in a quite complex ad hoc situation. The sea is becoming more important to Israel and she is gradually turning her attention more and more to maritime matters. It would be well if an orderly system of maritime boundaries and cooperation in utilizing the resources of the sea could be arranged with her neighbors, but that seems impossible for the forseeable future. It does seem likely, however, that in connection with or shortly after the forthcoming Law of the Sea Conference, Israel will as a minimum extend her territorial sea from six miles to twelve, while stoutly maintaining the right of free transit through international straits. © 1974 Taylor & Francis Group, LLC.

There existed clear demonstrations of nationalism in geography textbooks written by Americans during two significant epochs in the history of the United States. Geographies regarded the environment, people or institutions of the United States either with extreme adulation or subtle pride. They viewed the nation favorably when its strengths and weaknesses were compared to each other or to foreign elements, even when objective evidence did not support such an assessment. And, finally, they reached a host of young and impressionable Americans, and instilled in them a fervor for their country. © 1970 Taylor and Francis Group, LLC.

Beersheba has changed from a small agricultural settlement in pre-Biblical times to a city of importance in modern Israel. The wells and fertile loess soils of the Beersheba Basin have been utilized by all who have occupied the area. From 3300 B.C. to the present, Beersheba has functioned as an oasis, market town, military center, transportation node, and as a traditional gathering place for the Bedouin tribes of the Negev, Israel's southern desert. In 1900, the Ottoman Turks initiated the modern development of Beersheba. After World War I, the British administered the area as part of the Palestine Mandate. With the creation of the state of Israel in 1948, the city began to grow rapidly. In the early 1960′s, Beersheba had a population of over 52,000. It functions as the capital of a region containing over two-thirds of the national area. © 1965, Taylor & Francis Group. All rights reserved.

The aptitudes and abilities required for the position of programmer, within the computer industry, have yet to be fully studied and their inter-relationships known. Although the industry is relatively new, a substantial amount of research in the areas of personnel selection, evaluation and job requirements has been undertaken. Yet these studies have confined themselves primarily to the use of interest scales, aptitude and achievement tests as overall predictors for on-the-job success rather than in the study of the cognitive factors pertinent to the tasks of which programming is composed. In a study by Deutsch and Shea, Inc. (1963), the relationship between the programmer and the computer is seen as analogous to that of the mahout and his elephant. As with the mahout, the programmer uses his intelligence, skills and abilities in the control and guidance of a powerful and flexible, yet non-intelligent, tool in the performance of specific finite operations which contribute to the completion of more complex tasks. It is the programmer who, when presented with a problem from science, engineering or business, must work out a solution. John and Miller (1957) state that all problems have two general parts: the specific components involved (i.e., data, etc.) and the relationships which are the orderings of or changes to the specific components.

The localization ability of 10 normally hearing adults was determined under varying microphone separations and varying sound source azimuths. The stimuli (white noise bursts) were prerecorded, after being transduced through 'body' hearing aids and then played to the subjects over headphones. Results indicated that there was an improvement in localization ability for all azimuth conditions when the microphones were spaced wider than 12.7 cm apart (15.2-30.5 cm). The smaller the separations (5.5-12.7 cm), the poorer the localization. Localization was always poorer at 30° azimuth (the smallest used) than at any of the other azimuths (0° 30° 60° 90° right and left), regardless of microphone spacing. Implications are made about the relation of these findings to the use of binaural body aids on infants and young children. © 1977 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.

This study tested and confirmed the clinical impressions that (a) the novice psychotherapist may focus so much upon the exact words and nonverbal behavior patterns of his client (the process of making “concrete” statements) that he may lose sight of the larger picture that his client may be revealing at any given moment during the interview; (b) the experienced psychotherapist, on the other hand, seems to be responding to the words of the patient at a level of abstraction that attempts to integrate and understand the messages that the patient is trying to convey about himself; and (c) this latter process is reflected in the making of relatively more “abstract” comments than is true of the novice. S s were 24 first-year psychiatric residents and 19 staff psychologists and psychiatrists at a veterans hospital and a medical school. The learning theory implications of these findings is discussed. © 1976 Taylor & Francis Group, LLC.

What would appear to be the simplest of the sulphur-containing pyridine ligands, 2-mercaptopyridine, gives complex, poorly-characterized derivatives with transition metal ions [1, 2]. The conversion of this compound to 2-sulfenamidopyridine and the latter's coordination to divalent metal ions yields complexes in which, in every reported instance, bonding is through the two nitrogen atoms [3]. The Schiff base derivatives of 2-sulphenamidopyridine also give species which conform to the expected mode of complexation[3]. The complexes of 2,6-dimercaptopyridine have also been reported[4]. As with the monosubstituted derivatives, no clearly defined structure has been reported, although these complexes are thought to be highly polymeric species. In this communication, the synthesis and pattern of complexation of 2,6-disulphenamidopyridine and its Schiff-base derivative with 2-pyridinaldehyde are investigated. Particular emphasis is placed on the structures of the nickel(II) analogs. © 1968.

The ED50 of a strain of Serratia marcescens for microinjected instar III and IV gypsy moth larvae was 7.5 and 14.5 viable cells, respectively. Percentage and rate of mortality were found to be highly variable among replicates of the same instar and between instars in free-feeding bioassays. Mortality in second instar larvae occurred before ecdysis, whereas practically no mortality occurred in third and fourth instars until the molting period. Neither Boivin endotoxin preparations nor culture filtrates were toxic to instar III larvae when administered per os or by microinjection. Histological evidence indicated that the microorganism invaded the hemocoel of healthy or predisposed insects through the gut wall. The rapid multiplication of the bacterium in the hemocoel of infected insects, followed by death in the absence of extensive tissue damage, indicated mortality was due to a septicemia. The histological and biological evidence presented indicated that the microorganism would be less than effective if utilized as a conventional microbial insecticide. © 1976.

A gram-negative bacillus, pathogenic for gypsy moth larvae, was characterized culturally, morphologically, and physiologically as a member of the Serratia group of the family Enterobacteriaceae. The microorganism lacked the pigmentation characteristic of the group but was generally distinguished from closely related members of the family by its inability to produce gas from glucose, inositol, glycerol, and cellobiose; its rapid liquefaction of gelatin; and its failure to ferment raffinose or arabinose. The microorganism displayed lecithinase, deoxyribonuclease, and chitinase activity. The percentage of G + C in DNA from this bacterium was within the range reported for known strains of Serratia marcescens. © 1976.

1. 1. The influence of thermal acclimation on cable constants of the median giant axon of earthworms, Lumbricus terrestris L., has been studied using standard intracellular stimulating and recording techniques. 2. 2. Acute cooling of axons from warm-acclimated worms resulted in changes in cable constants, some of which were partially compensated for (reversed) after cold acclimation. 3. 3. Of special interest is the relative behavior of specific axoplasm resistance in response to acute temperature change in warm- and cold-acclimated worms. 4. 4. The results suggest that thermal acclimation alters the properties of the axoplasm and that the resulting changes in cable constants contribute to compensatory adjustments in nerve conduction velocity after acclimation. © 1973.
