Geology of West Africa and Canary and Cape Verde Islands

Abstract: West Africa consists essentially of a Precambrian granitized craton (radiometric ages of 2700 to 1600 my) covered by a thin sedimentary blanket, the oldest sedimentary rocks being as much as 1000 my old The Precambrian basement has been warped into three major uplifts trending approximately east-northeast (Fig 1): the Leo uplift (Dorsale de Leo, also known as the Liberia-Upper Volta uplift, and Bouclier eburneen); the Reguibat uplift; and the Anti-Atlas uplift Deposition during most of Paleozoic time apparently occurred in epicontinental seas The principal preserved depositional areas are the Taoudeni basin in Mauritania and Mali (Fig 2); the Tindouf basin in Morocco, Algeria, Mauritania, and Spanish Sahara; the Volta basin in Ghana and Upper Volta; and the Bove basin in Guinea and Portuguese Guinea

Lower Turbulent Zones Associated with Mountain Lee Waves.

Abstract: The characteristics of the lower turbulent zone (LTZ) which is associated with mountain lee waves have been investigated through the analysis of aircraft observations made near Boulder, Colo. Numerical filters and statistical analysis techniques have been applied to the data from six cases to yield vertical sections of potential temperature, horizontal wind, and turbulence intensity along the aircraft paths. One case study is presented to illustrate the structure of the LTZ and its changes during a frontal passage. In addition, the main features of all the analyses are summarized in the form of a schematic vertical section. The horizontal dimension of the LTZ varied between 25 and more than 65 km downstream of the first lee wave trough. The vertical dimensions ranged from a few hundred meters AGL at the lee wave troughs to 3 km AGL at the wave crests. Turbulence levels were light, moderate or severe over more than 90% of the total distance flown in the LTZ (nearly 1100 km). Severe turbulence was ...

Styles of community policing

Abstract: Police agencies have distinctive philosophies, or styles, of policing. James Q. Wilson identified three policing styles by analyzing the approach of police in order-maintenance and law enforcement situations Styles can also be developed by considering policing methods in relation to their impact upon the general community. The reactive-procrctive emphasis given to wrious combinations of positive and negative methods, or counselor and enforcer roles, is the basis for the four policing styles discussed.

Middle Paleozoic Off-Shelf Deposits in Southeastern California: Evidence for Proximity of the Antler Orogenic Belt?

Abstract: The middle Paleozoic section in the west-central Inyo Mountains comprises two sequences: a Silurian to Middle Devonian calcareous sequence, which was extensively channeled in a submarine environment during Middle or Late Devonian time, and an Upper Devonian(?) to Mississippian predominantly clastic sequence. Distribution of facies in the lower calcareous units indicates a northwest-inclined paleoslope. The clastic sequence includes enormous quartzite and carbonate clasts that originated near the western North American shelf edge, and smaller chert and mudstone clasts formed during excavation of submarine canyons into slope deposits. Coarse clastic material was emplaced by submarine debris flows and turbidity currents moving down the northwestward-dipping paleoslope. Middle Paleozoic conglomerate in the west-central Inyo Mountains has been interpreted as indicating the proximity of the Antler orogenic belt to the west. However, as the paleoslope dipped northwestward throughout middle Paleozoic time, and the conglomerate was derived from the North American shelf edge and slope to the southeast, the presence of this conglomerate must be dismissed as evidence for extension of the Antler orogenic belt into southeastern California.

The influence of substrate characteristics on the contact angles between liquid gallium and gallium arsenide crystals

Abstract: Parameters influencing the interfacial interaction between liquid gallium and single crystalline gallium arsenide were investigated under vacuum by means of the sessile-drop technique over the temperature range ∼ 30 to 200° C. In addition to their dependence on the anisotropy of the {111} planes, contact angles in the Ga(I)/GaAs(s) system were found to be sensitive to the degree of misorientation and the direction of tilt of these planes. Furthermore, contact angles were found to be dependent on the size of the liquid drop and on the surface roughness of the substrate. In agreement with theoretical expectations the measured angles increased with increasing roughness of the GaAs surfaceS. However, these angles were found to be unaffected by the presence of N2, Ar, and He atmospheres, and by the nature and concentration of charge carriers in the substrate.

Decade Differences in Personality of Junior College and University Freshmen.

Abstract: Random samples of freshmen at a junior college and a university were administered 5 scales from the California Psychological Inventory in 1958–60, and to similarly obtained samples from the same institutions in 1970–71. The Ns were 75 males and 75 females each time at the junior college, and 100 males and 100 females each time at the university. Significant decade differences in mean scores by sex group were obtained for 12 of the 20 comparisons with 1970-71 groups having the lower means. The differences were generally toward a less psychologically mature direction.

Effects of angular acceleration on man: choice reaction time using visual and rotary motion information

Abstract: This experiment was concerned with the effects of rotary acceleration on choice reaction time (RTc) to the motion of a luminous line on a cathode-ray tube. Specifically, it compared the (RTc) to rotary acceleration alone, visual acceleration alone, and simultaneous, double stimulation by both rotary and visual acceleration. Thirteen airline pilots were rotated about an earth-vertical axis in a precision rotation device while they observed a vertical line. The stimuli were 7 rotary and visual accelerations which were matched for rise time. The pilot responded as quickly as possible by displacing a vertical controller to the right or left. The results showed a decreasing (RTc) with increasing acceleration for all conditions, while the (RTc) to rotary motion alone was substantially longer than for all other conditions. The (RTc) to the double stimulation was significantly longer than that for visual acceleration alone.

On the Nature of Marital Relationships: Measurable Differences in Spontaneous Agreement

Abstract: The Spontaneous Agreement (SA) scores on a lengthened form of the Ferreira-Winter Questionnaire of 242 normal and 177 abnormal couples were compared in a cross-sectional study, taking into account the duration of their marriage. For those couples married a short time, SA did not differ for the two groups. The overall SA was higher for normals, and the longer the normal couples were married, the higher their SA. SA did not increase with duration of marriage for abnormal couples. Both groups had higher SA scores than synthetically matched couples.

Choice-reaction time to visual motion with varied levels of simultaneous rotary motion.

Abstract: Twelve airline pilots were studied to determine the effects of whole-body rotation on choice-reaction time to the horizontal motion of a line on a cathode-ray tube. On each trial, one of five levels of visual acceleration and five corresponding proportions of rotary acceleration were presented simultaneously. Reaction time to the visual motion decreased with increasing levels of visual motion and increased with increasing proportions of rotary acceleration. The results conflict with general theories of facilitation during double stimulation but are consistent with neural-clock model of sensory interaction in choice-reaction time.

The Effect of Spurious Angular Accelerations on Tracking in Dynamic Simulation

Abstract: A laboratory study was conducted to investigate the effect of spurious simulator yaw motions on a pilot's control performance. A second objective was to compare the efficiency of static and dynamic simulator tracking in previously unexamined vehicle dynamics. Twelve airline pilots served as subjects in a moving-base flight simulator under congruent-motion, spurious-motion, and no-motion conditions. The results indicated a significant increase in the amount of error with increasing levels of spurious motion during the initially administered series of trials. The influence of spurious motion, however, was absent in a second series of trials. The data suggest that the pilots learned to compensate in their performance for the spurious inputs. It was also found that congruent visual and rotational cueing produced superior performance to that of tracking with visual information alone.

Philosophical Investigations Remark 43 Revisited

Abstract: In the first paragraph of 43 Wittgenstein is saying that in many cases, the term 'meaning', where the concern is with the definition (= explanation) of a word, can be defined as the use of the word in the language. One can say this if one is concerned with definition, if one needs or wants to define the word 'meaning'. There is an ambiguity about whether Wittgenstein is concerned with a large class of cases of meaning or a large class of cases of word meaning. D. Gustafson argues that Wittgenstein is concerned with the former, contrasting a large class of cases of word meaning with another class of cases including the meaning of life ('On Pitcher's Account of Investigations ?43,' Philos. and Phen. Research, I967). I think that the latter reading is more plausible. Wittgenstein is concerned with a large class of cases of word meaning which is explainable by use, contrasting it with a smaller class of cases of word meaning which is not explainable in this way. Wittgenstein is not concerned enough with non-linguistic meaning such as the meaning of life or clouds meaning rain to want to set it aside here. MIore important, this reading fits in nicely with the second paragraph of 43 which most commentators simply ignore. The meaning of some words, namely some names, is explained not by use but by pointing to the bearer of the name. There are at least two reasons why Wittgenstein does not write of all word meaning in 43. First, one of Wittgenstein's main themes in the Investigations is that language is diverse and multiform. There are countless kinds of words and sentences (I I, 23). They are not countless because there is an infinite number of them but rather because there are many different ways of grouping kinds of words (17). Language does not have an essence if an essence is something present in all language which makes us

Peripheral visual response time to colored stimuli imaged on the horizontal meridian

Abstract: Two male observers were administered a binocular visual response time task to small (45 min arc), flashed, photopic stimuli at four dominant wavelengths (632 nm red; 583 nm yellow; 526 nm green; 464 nm blue) imaged across the horizontal retinal meridian. The stimuli were imaged at 10 deg arc intervals from 80 deg left to 90 deg right of fixation. Testing followed either prior light adaptation or prior dark adaptation. Results indicated that mean response time (RT) varies with stimulus color. RT is faster to yellow than to blue and green and slowest to red. In general, mean RT was found to increase from fovea to periphery for all four colors, with the curve for red stimuli exhibiting the most rapid positive acceleration with increasing angular eccentricity from the fovea. The shape of the RT distribution across the retina was also found to depend upon the state of light or dark adaptation. The findings are related to previous RT research and are discussed in terms of optimizing the color and position of colored displays on instrument panels.

Formation and Rigidity of First Impressions as a Function of Perceived Associations

Abstract: The impetus for the study was the familiar experience, upon initial exposure to a person, of feeling that he or she somehow reminds one of someone else. Curiously, although there is a considerable literature on stereotyping of categories or classes of people (e.g., Brigham, 1971; Katz & Braly, 1933; Prothero’& Melikian, 1955), there has been no systematic research into the effects of interpersonal associations with a previously-encountered individual. on evaluative judgments of a very recentlyencountered person.. Along these lines, the present study was designed to investigate the effects of such associations on the formation and modi-

The Campus Ombudsman

Abstract: The ombudsman concept has survived 162 years of operations first in the Scandina ian countries, was later developed with some adaptation in the English speaking nations, and has emerged as a unique, efficient, and inexpensive complaint response mechanism for the facile resolution of an individual citizen's complaint. In the United States, however, the potential conflict be tween elected officials and the ombudsman when both attempt to serve the citizen-voter, and other reasons have deterred development of the ombudsman in the United States. But the ombudsman has uniquely de veloped in colleges and universities. Throughout the country there are now approximately 65 campus om budsmen. California appointed 17 campus ombudsmen within a three-year span beginning in 1968. The move ment has not been devoid of difficulties. Characteristi cally, when administrators, faculty, students, and staff are queried about the office, responses are usually sup portive. But differences emerge, particularly regarding financial support. If the ombudsman role remains undefined, confusion will continue and may lead to an early demise, that is to say, the removal of funds for the ombudsman func tion. This article presents a summary of a doctoral dis sertation which probed deeply into the ombudsman issue. Its central concern was what the role ideally should be as compared with what is currently practiced. Included is a statement of the problem, methodology, findings, conclusions, and recommendations. The findings should provide some insight for students of the idea and guide lines for initiating an ombudsman on a college or uni versity campus. The study sought to determine the extent of con sensus or dissensus on the role behavior of California campus ombudsmen as perceived by four selected groups: ombudsmen, executive-academic administrators, faculty, students. The focus of concern involved four areas: (1) major duties and among whom performed, (2) conflict management procedures, (3) twenty areas of college activity, and (4) institutional and financial support. Confusion as to ombudsman role has come about in part because of lack of a widely agreed upon role model, in-depth experience, and varied function empha sis from campus to campus. Conflict has been inevitable between principal actors and groups served, faculty leaders, key college officials, and student leaders. Om budsmen have been particularly vulnerable. Their leader ship has diminished. Most serious, the normal and pro fessional growth of the office and, thus, its effectiveness, has been endangered. The term "ombudsman," by its multiplicity of uses, has become diffused and thus weak ened. Additional dangers exist. The term itself can be come easy prey for those wishing to exploit its novelty. It may be captured and placed in the vest pocket of ad ministration, faculty, or students. In California univer sity and college environments, ombudsmen must look carefully at their salary and authority source before expressing a strong criticism or recommending a sub stantive change in the college bureaucracy. Data were collected principally by means of a 29 item questionnaire and interviews. Other sources of information were three years on-the-job experience, a survey entitled "Control Variables of an Ombudsman in an Educational Setting," the literature, and personal interaction with other California campus ombudsmen. The 153 subjects polled included all IS existing Cali fornia campus ombudsmen and more than twice that number of high level administrators, faculty, and stu dents. Wherever an ombudsman was operating, the president, chancellor, or other high-level administrators were included. All selected administrators, faculty, and students must have had a working knowledge of the ombudsman as well as negative and positive contacts with the office.

The Use of an Auxiliary Matrix to Count Trees in Bipartite and Complete Graphs

Abstract: Use is made of an auxiliary matrix to count trees of complete bipartite graphs. One form of the auxiliary matrix achieves partial diagonalization of the node admittance matrix and a second form of the same matrix completes the enumeration. Extension of the results is shown to be compatible with a known count for trees of complete graphs.
