Photoelektronen-Spektren von Nichtmetall-Verbindungen und ihre Interpretation durch MO-Modelle†

Abstract: Die Ergebnisse der (Niederenergie-)Photoelektronen-Spektroskopie ermoglichen ein besseres Verstandnis der „Natur der chemischen Bindung”. Die Anwendbarkeit der neuen Mesmethode wird in diesem Beitrag an reprasentativen Verbindungen der Nichtmetalle vorgefuhrt, und es wird die enge Symbiose mit Orbital-Modellen aufgezeigt. Diskutiert werden insbesondere allgemeine Folgerungen betreffend Elektronenmangel, π- und σ-Wechselwirkungen, Elektronenpaardelokalisation und Substituenteneffekte oder geometrische Storungen. Photoelektronen-spektroskopische Ionisierungsenergien erlauben, Energie-Parameter fur bestimmte Molekulgruppierungen abzuschatzen, lassen sich mit zahlreichen weiteren Mesdaten korrelieren und sind auch fur den Unterricht in „Allgemeiner Chemie” didaktisch wertvoll.

Photoelectron Spectra of Nonmetal Compounds and Their Interpretation by MO Models

Abstract: The results of (low energy) photoelectron spectroscopy render possible a better appreciation of the “Nature of the Chemical Bond”. The application of this new experimental method is demonstrated utilizing representative compounds of the nonmetal elements, and a close symbiosis delineated with molecular orbital models. In particular, general consequences are discussed concerning electron deficiency, σ- and π-interactions, electron pair delocalization, and substituent effects or geometric perturbations. Photoelectron spectroscopic ionization energies permit evaluation of parameters for specified molecular groups, allow correlation with numerous other experimental data, and are didactically valuable in the teaching of general chemistry.

Influence of the developmental schedule of puberty on learning and ego functioning.

Abstract: Developmental schedules refer to temporal factors of pubertal processes as they might bear on ego development. The longitudinal research reviewed here from the 30-year archives of the Guidance Study of the Institute of Human Development pertains to the effects of varying lengths of the prepubertal and pubertal period on the short-term and enduring integration of drive states initiated at puberty. The personality correlates of varying lengths of these periods serve as vehicle for establishing properties of these stages as well as of the transition between them. The different ways the sexes respond to the early onset of puberty, as reported here, may provide an important microcosm for understanding normative sex differences in the general regulation of drive states.

An Atmosphere on Ganymede from Its Occultation of SAO 186800 on 7 June 1972.

Abstract: On 7 June 1972 the third, Jovian satellite Ganymede occulted the eighth-magnitude star SAO 186800. Successful photoelectric observations obtained at Lembang, Java (Indonesia), and Kavalur, India, show nonabrupt immersions and emersions, indicating the presence of an atmosphere whose surface pressure is greater than about 10^(-3) millibar. By fitting the two occultation durations as chords to a model disk, the diameter is found to be 5270 (+30, -∼200) kilometers, the major error contribution arising from the uncertain atmospheric thickness below the occultation layer. The derived mean density is 2.0 (-0.03, + ∼0.2) grams per cubic centimeter.

The special child in the regular classroom.

Abstract: Three educable mentally retarded children who had previously been placed in special self contained classrooms were integrated with 22 nonhandicapped children in a third grade classroom during the first year of the North Sacramento Model Program. A similar number were integrated into a fourth grade classroom during the second year of the project. A precision teaching procedure was used with both experimental groups. Control groups of educable mentally retarded and educationally handicapped children in regular classrooms were maintained. Results indicate that the handicapped and nonhandicapped children in the integrated setting improved as much or more than did their controls in academic skills, social behavior, and attitude change.

Nuclear Magnetic Resonance Studies of Ferric Porphyrins

Abstract: During the past five years there has been a great increase in the use of proton magnetic resonance spectroscopy (PMR) in investigating structure and structurefunction relationships in a variety of biological macromolecules containing paramagnetic metal Paramagnetism of the molecule can serve as a very sensitive and specific probe for the environment of the metal ion by causing large perturbations3 on the normal diamagnetic linewidths and chemical shifts of the protons. Since the interactions with the unpaired electrons are relatively short-range, only nuclei in the immediate vicinity of the metal ion are appreciably affected by the paramagnetism. If the exact origin of the proton-electron interaction is understood, considerable information on bonding and molecular configuration can be extracted from the linewidth and shift data. Although a variety of protein systems have been investigated by PMR,4-24 the two systems which have received the most attention and in which the technique has been most successful are the iron-sulfur p r ~ t e i n s ~ ' ~ * ~ such as ferridoxin, and the heme-iron proteins, cytochrome C , ~ I ~ the myoglobins,'3-20 and hemoglobins. 21-2 For the iron-sulfur proteins, PMR has been instrumental in e l u ~ i d a t i n g ~ * ~ ~ the antiferromagnetic coupling between irons in the twoand eight-iron species. For the heme-iron proteins, which are the systems of interest here, PMR data have proved valuable in the investigation of a variety of properties. Among the prominent examples of such studies are the detection of changes in tertiary and quaternary structure of hemoglobins, 21-23 the study of bonding, configuration and electron-transfer properties in cytochrome C , ~ O ' ' the probing of the environments of the iron in a number of myoglobins,13-19 and the location of magnetic axes within the porphyrin plane of myoglobin.20 The characteristic feature of the PMR spectra which facilitated these interpretations is that the paramagnetic (isotropic) shifts for the porphyrin and axial ligand protons are sufficiently large to move the peaks well outside the range of proton shifts commonly observed for analogous diamagnetic proteins,' i.e., 0 to -10 ppm from TMS. Although considerable useful information has been derived from these observed shifts, a clear understand-

Attitudes of children toward their special class placement.

Abstract: be worked on during the 3 month preparation for placement and what placement might be ?ppropriate. Although the psychological examtner also obtained Stanford-Binet Scale, Vineland Social Maturity Scale, and other test data, the examiner reported that the referral rating form provided immediate information which Was used to focus on individual child training programs. The parents' data also provided a qUick method of identifying which behaviors should be discussed with parents and which behaviors can or should be the focus of parent training procedures. Although the data collected thus far suggest the referral rating form has great promise, the true' value of such a tool can only be ?etennined by its broad utility in the field. The Ultent of this article is to make the form public and to encourage its use in a variety of settings for the purposes appropriate to the particular Setting. Further, it is anticipated that although as a general form it may not be appropriate for some setting, if such a tool is needed, it is hoped that the form will be modified accordingly. Although the form has only been Used with retarded populations, it may be of Use in various early child development screening programs. ----------------R.olf A.

Observations on the gametolytic gland in the anaspidean opisthobranchs, Phyllaplysia taylori and Aplysia californica†

Abstract: The wall of the gametolytic gland in Aplysia and Phyllaplysia consists of a muscular layer lined with an epithelium incorporating four distinct cell types, some of which show intense secretory activity. The cytoplasm of these cells, rich in RNA, has a peripheral layer of densely-packed mitochondria in association with a smooth endoplasmic reticulum. Lipid globules, perhaps resulting from absorption of lumen contents by microvilli, appear in the cytoplasm in the course of growth and reproductive activity. A basal band of fibrillar material appears to serve as a cytoplasmic skeleton. The elaboration of cell types, extensive areas of cytoplasmic RNA, and vigorous secretory activity suggest important roles for this organ such as development of food reserves, recycling of sexual materials of high physiological value, and interaction with the bag cells of the nervous system in coordinating ovulation with the availability of capacitated, exogenous sperm.

Adjustment and Value Conflict in Urbanizing Dakota Indians Measured by Q-Sort Technique'

Abstract: As part of a larger study of American Indian migration to the San Francisco Bay Area, a Q-Sort test was devised to discover and measure value conflict Methodological problems in the administration and analysis of the test are discussed. In addition, comparison of the performance of selected individuals with their observed behavior shows that individual behavioral change in acculturation cannot be described in linear acculturation continuum models Some alternative hypotheses are proposed. THERE IS NO ADVANTAGE to be gained by rehashing all the arguments over the relative merits of quantitative testing and ethnographic description in the study of cultural-psychological processes. Others have done this with more interest, energy, and rigor than is appropriate here. This report is an attempt to integrate results of these two investigative methods with results not originally foreseen, and to point out some propositions about value conflict in acculturation that developed from this analysis.

Predicting the Readiness of Elementary School Children to Learn an Effective Dental Flossing Technique

Abstract: Data on age and sex and the results of the Moore Eye-Hand Coordination Test were analyzed to determine the relationships that existed between these variables and the time it took the individual to learn how to manipulate dental floss between all of the teeth and how to clean the teeth effectively with dental floss. An analysis of data on 117 Lebanon, Ore, elementary school children, 8 through 11 years of age, revealed that there were significant relationships between age (or eye-hand coordination) and flossing-manipulation skill and the ability to effectively remove plaque with dental floss. Although sex was not highly correlated with flossing-manipulation skill and flossing effectiveness, there were some significant differences between the boys and girls at certain age levels in either the flossing-manipulation skill or the flossing-effectiveness tests. The analysis revealed that the variables of age, sex, and eye-hand coordination could not precisely predict when particular students were ready to learn an effective dental flossing technique. Finally, data revealed that all 8-, 9,- 10-, and 11-year-old youngsters could learn how to use dental floss effectively within ten, seven, six, and five days, respectively.

Glossolalic speech from a psycholinguistic perspective.

Abstract: This is a psycholinguistic study of glossolalia produced by four speakers in an experimental setting. Acoustical patterns (signal waveform, fundamental frequency, and amplitude changes) were compared. The frequency of occurrence of vowels and consonants was computed for the glossolalic samples and compared with General American English. The results showed that three of the four speakers had substantially higher vowel-to-consonant ratios than are found in English speech. Phonology, morphology, and syntax of the four glossolalic productions were analyzed. This revealed two distinct forms of glossolalia. One form, which we called “formulaic” tends towards stereotypy and repetitiousness. The second form, which we called “innovative” shows more novelty and unpredictability in the chaining of speech-like elements. These contrastive forms of glossolalia may relate to dimensions of linguistic creativity. Precise correlates with personality patterns, educational backgrounds, psychopathology, and other sociolinguistic variables remain to be employed.

Brainstorming in large groups as a facilitator of children's creative responses.

Abstract: Summary Six groups of fourth graders (N = 122) from three private schools seated in formal classroom settings were given an unusual-uses problem, and for a 10-minute period they either brainstormed as a total group or brainstormed individually. In the second phase of the experiment, all groups brainstormed individually for five minutes. In two schools (four groups), those who had engaged in group brainstorming in the first phase made significantly more responses and demonstrated a higher level of creativity than those who had brainstormed individually in both phases. Differences for the third school were not significant. Results for these two schools with their traditional classrooms are consistent with the results of experiments with adults showing that brainstorming in small, informal groups tends to facilitate creativity in subsequent problem-solving sessions. Additional research is needed to determine the extent to which such factors as general arousal, normative effect, imitation, or reinforcement co...

Alcohol ingestion following intracerebral angiotensin administration and water deprivation

Abstract: Rats which drank a significant amount of water when angiotensin was injected into the septum were allowed to choose between 4, 8 and 12% ethanol following angiotensin administration and following 24 hr water deprivation. Ethanol intake was similar under both conditions. The results indicate that drinking following central angiotensin administration has some of the motivational properties of normal thirst.

Individual differences and field dependence in the Pulfrich effect, a re-examination.

Abstract: Many explanations and conflicting data characterize search for understanding the Pulfrich effect. The conventional filter and the episcotister were each used to create the Pulfrich effect. Individual differences in observations by 9 field-dependent and 9 field-independent Ss were measured. Field-independent Ss see a longer minor diameter of the ellipse in the Pulfrich effect than field-dependent Ss. These data support a differential latency in perceptual response.
