My sister's keeper: Negative effects of social welfare and affirmative action programs on black women

The campaign rhetoric of a former neo-Nazi and Klan grand wizard who won a seat in the Louisiana state legislature in 1989 encapsulated two of this article's key points: that black women on welfare bear the brunt of derision, anger, and calls for their forcible control, and that black women who use affirmative action programs for advancement bear the brunt of derision, anger, and calls for their systematic devaluation. This white backlash is one of the negative effects of social welfare and affirmative action programs described in the article, which focuses on black women because of their particular vulnerability in a sexist and racist society. The article is both a warning to black women of an insidious widening gap between their haves and have-nots, and a plea that they work hard together to close this gap by acknowledging the fundamental similarities of their struggles to survive, and by recognizing that they and their children need each other to effectively continue the struggle.     

Interaction of color and geometric cues in depth perception: When does “red” mean “near”?

Luminance and color are strong and self-sufficient cues to pictorial depth in visual scenes and images. The present study investigates the conditions under which luminance or color either strengthens or overrides geometric depth cues. We investigated how luminance contrast associated with the color red and color contrast interact with relative height in the visual field, partial occlusion, and interposition to determine the probability that a given figure presented in a pair is perceived as nearer than the other. Latencies of near responses were analyzed to test for effects of attentional selection. Figures in a pair were supported by luminance contrast (Experiment 1) or isoluminant color contrast (Experiment 2) and combined with one of the three geometric cues. The results of Experiment 1 show that the luminance contrast of a color (here red), when it does not interact with other colors, produces the same effects as achromatic luminance contrasts. The probability of near increases with the luminance contrast of the color stimulus, the latencies for near responses decrease with increasing luminance contrast. Partial occlusion is found to be a strong enough pictorial cue to support a weaker red luminance contrast. Interposition cues lose out against cues of spatial position and partial occlusion. The results of Experiment 2, with isoluminant displays of varying color contrast, reveal that red color contrast on a light background supported by any of the three geometric cues wins over green or white supported by any of the three geometric cues. On a dark background, red color contrast supported by the interposition cue loses out against green or white color contrast supported by partial occlusion. These findings reveal that color is not an independent depth cue, but is strongly influenced by luminance contrast and stimulus geometry. Systematically shorter response latencies for stronger near percepts demonstrate that selective visual attention reliably detects the most likely depth cue combination in a given configuration.     

Female delinquency in the emancipation era: A review of the literature

By the mid-1970s studies began to indicate that the era of women's emancipation had been accompanied by changes in the volume and character of female lawbreaking. In this paper, I critically review the growing literature that has attempted to measure and explain the alleged changes in female delinquency. I examine whether females have remained traditional in their delinquency patterns, whether the observed changes (if they exist at all) are real or the result of changing societal reactions, and whether female delinquents have been masculinized or in other ways influenced by the women's liberation movement or changing gender roles. I also review explanations of female delinquency that are derived from social control, power-control, strain, and subcultural theories. Finally, I argue that more attention needs to be given to understanding the role strain inherent in females' attempts to negotiate ambiguous or contradictory gender roles, and that the concept of role strain offers a promising explanation of contemporary patterns of female delinquency.Portions of this paper were adapted from R. J. Berger (Ed.), The Sociology of Juvenile Delinquency, Chicago: Nelson-Hall, 1990 forthcoming.     

Perceptual scission of surface-lightness and illumination: An examination of the gelb effect

Summary An attempt was made to examine how the photometric equation: luminance (L)=albedo (A)×illuminance (I) could be solved perceptually when a test field (TF) was not seen as figure, but as ground. A gray disk with two black or white patches was used as the TF. Illuminance of the TF was changed over 2.3 log units and TF albedo was varied from 2.5 to 8.0 in Munsell value. Albedos of the black- and white-appearing patches were 1.5 and 9.5 in Munsell values, respectively. Two types of category judgments for apparent TF lightness (A) and apparent overall illumination (I) were made on the total of 40 TFs (5 illuminances×4 TF-albedos×2 patch-albedos). The results indicated that when the black patches were added to the TF, A was indistinguishable from I and when the white patches were placed on the TF, A and I could be distinguished from each other. The Gelb effect was interpreted as a manifestation of such A–I scission. It was concluded, therefore, that as far as the Gelb effect was observed, the perceptual system could solve the equation, L=A×I, in the sense that for a fixed L, the product of A and I would be constant.     

A Translation of Intuitionistic Predicate Logic into Basic Predicate Logic

Basic Predicate Logic, BQC, is a proper subsystem of Intuitionistic Predicate Logic, IQC. For every formula in the language {, , , , , , }, we associate two sequences of formulas 0,1,... and 0,1,... in the same language. We prove that for every sequent , there are natural numbers m, n, such that IQC , iff BQC n m. Some applications of this translation are mentioned.     

Beholding the beholder: The reception of “Dutch” painting

While a lucid and understandable interpretation can be given for most pictures, typically Dutch paintings (i.e. seventeenth-century genre and still-life pictures) seem to allow for or even demand some measure of freedom for the beholder. The cause of this ambiguity lies in the typically Protestant disregard for works of art and in a concomitant characteristic of these works: they address the viewer in an ethical manner.In memoriam Sixten Ringbom, 1935-1992     

African American Dance - Philosophy,Aesthetics, and ‘Beauty’

This essay considers the recuperation of beauty as a productive critical strategy in discussions of African American dance. I argue that black performance in general, and African American concert dance in particular, seeks to create aesthetic sites that allow black Americans to participate in discourses of recognition and appreciation to include concepts of beauty. In this, I suggest that beauty may indeed produce social change for its attendant audiences. I also propose that interrogating the notion of beauty may allow for social change among audiences that include dance theorists and philosophers. Through a case-study consideration of work by three African American choreographers, Donald Byrd (b. 1949), Ulysses Dove (1947 – 1996), and Abdel Salaam (b. 1949), I ultimately hope to suggest critical possibilities aligning dance performance with particular aesthetic theory relevant to its documentation and interpretation.     

Religion and mental health among blacks

The positive role of religion in the mental health of black Americans is a much neglected theme in the literature. This paper considers religion as one of the important retained black cultural traits, which continues to play a vital role in the mental health and survival strategies of black Americans. The paper examines Grier and Cobbs's appraisal of the religion-mental health connection in black communities and identifies different ways for mental health practitioners to think about religious phenomena and the primal partnership between religion and mental health. The paper concludes with a challenge to keep awareness of the religion-mental health partnership together in the treatment of black Americans.This paper was originally presented at a two-day conference on Some Dynamics and Psychotherapeutic Methods in Rendering Treatment to Blacks, March 15 and 16, 1980, in Oakland, California. This particular paper discussed religion as one of the important retained black cultural trains.     

Mary McLeod bethune and the education of black girls

Traditional definitions of feminism do not hold for some black women like Mary McLeod Bethune who had to overcome the dual burdens of race and sex in order to build a school for black girls in the racially tense South during the early part of the 20th century. Ever a pragmatist, Bethune seized the opportunity offered by the rhetoric of domesticity and certain stereotypical views of blacks in order to advance the higher cause of uplift and self-sufficiency for black women through education.     

Sexual coercion in high school dating

Retrospective data from a survey of Australian undergraduate university students indicated that sexual coercion leading to sex play and sexual intercourse is a feature of dating behavior in high school. Fifty-three percent of 217 females reported that a boy had overestimated the level of sexual intimacydesired, while 45 percent of 72 males reported that a girl had underestimated the level of sexual intimacydesired. While data was not gathered on ethnic origin, the majority of students were Australian born, although family of origin would have been culturally varied. The data illustrate sexual coercion leading to both sex play and intercourse, with a number of factors being implicated in its occurrence, including alcohol and drugs and males saying things they didn't really mean, through to threat and use of force. They support that the existence of sexual coercion among high school students, a population that has received little research attention in this area, is comparable to its existence in the college/university years.     

Discrimination and matching within and between hues measured by reaction times: some implications for categorical perception and levels of information processing

Summary Same-different reaction times (RTs) were obtained for pairs of color samples ranging perceptually from blue to green. In Experiment 1, observers responded with same if both stimuli in a pair were from the same hue category (i.e., blue-blue or green-green) or different if the two stimuli were from different hue categories (i.e., blue-green or green-blue). RT for same responses was faster for pairs of physically identical stimuli (A-A) than for pairs of physically different stimuli (A-a) belonging to the same hue. RT for different responses was faster for larger physical differences across a boundary between hues (A-B 6 step) than for smaller physical differences (A-B 2 step). Experiment 2 replicated and extended these findings: In one phase observers matched pairs of stimuli as same or different by categorical similarity as in Experiment 1, and in a second phase observers matched the same stimulus pairs, this time by physical similarity. Matching by categorical similarity replicated the pattern of results found in Experiment 1. Matching by physical similarity showed that RTs for different responses were equivalently fast independent of the physical difference between A-B pairs, but were faster for A-B than for A-a comparisons. Further, matching identity was faster under categorical match instructions than under physical match instructions. Results of the two experiments support a model of parallel processing of physical and categorical stimulus information in color perception. Further, these reaction-time data and their implications in color perception (for hues) parallel reaction-time data and their implications in speech perception (for phonemes).     

Women and “body-isms” in television beer commercials

Research on women in print advertisements has shown that pictures of women's bodies and body parts (body-isms) appear more often than pictures of men's bodies. Men's faces (face-isms) are photographed more often than their bodies. This present study is the first to confirm this finding for television commercials. Results showed that men appear twice as often as women in beer commercials. The body-isms of women significantly outnumbered the body-isms of men. Women also appeared in swimwear more often than men, thus increasing the photo opportunities for body-isms. This study raises concerns about the dehumanizing influence of these images in beer commercials, and their association with alcohol use and the violence in the televised sporting events during which beer commercials are frequently aired.     

Color preference,arousal, and the theory of psychological reversals

The theory of psychological reversals asserts that there are two levels of preferred felt arousal, one high and one low. Only one of them is preferred at a given time, although discrete switches (reversals) occur from time to time, so that each level is preferred at different times. In order to document such changes in preferred levels of arousal, 75 subjects were asked to make color preference choices at regular intervals during their working day, some for as many as 8 days. The assumption was that different colors are arousing or relaxing, and that color choice indicates arousal preference. The typical patterns of color choices that occurred clearly displayed the expected reversal effect over time and were considerably more consistent with reversal theory than with optimal arousal theory. In a second study, 41 new subjects were asked to respond to a simple mood adjective checklist each time they made their color preference choices. The results strongly supported the association between arousal preference and color preference and also supported the reversal theory thesis that low arousal preference is associated with seriousness and planning orientation (all these characterizing the telic state), and that high arousal preference is associated with playfulness and spontaneity (all these characterizing the paratelic state). Finally, both studies showed that there is a systematic tendency for long-wavelength colors to induce feelings of high arousal and for short-wavelength colors to induce feelings of low arousal.     

Attention and distractibility during reading in hyperactive boys

Nonhyperactive and clinically defined hyperactive boys were administered reading tasks under quiet and distracting conditions. Hyperactive boys were less attentive to task relevant stimuli and more attentive to task irrelevant stimuli than their controls. Our results demonstrate that the previous findings of inattentiveness among hyperactive boys on laboratory tasks can be generalized to more typical school activities such as reading.     

Computer content analysis of sex differences in the language of children

This study presents empirical procedures for the collection and content analysis of the oral language of kindergarten children. The analysis technique used material and machines available to most researchers. The results of the analysis of language samples of 144 randomly selected children from the entire kindergarten class of the Ithaca, New York, school system showed that boys produced significantly more language than did the girls as well as significantly more references to aggression, self, time, space, quantity, fears, good, act of oral communication, negation, and affirmation, and asked more questions of the examiner than did the girls. The girls made significantly more female references than did the boys. Implications for future research are discussed.     

Cooperation,Knowledge, and Time: Alternating-time Temporal Epistemic Logic and its Applications

Branching-time temporal logics have proved to be an extraordinarily successful tool in the formal specification and verification of distributed systems. Much of their success stems from the tractability of the model checking problem for the branching time logic CTL, which has made it possible to implement tools that allow designers to automatically verify that systems satisfy requirements expressed in CTL. Recently, CTL was generalised by Alur, Henzinger, and Kupferman in a logic known as Alternating-time Temporal Logic (ATL). The key insight in ATL is that the path quantifiers of CTL could be replaced by cooperation modalities, of the form , where is a set of agents. The intended interpretation of an ATL formula is that the agents can cooperate to ensure that holds (equivalently, that have a winning strategy for ). In this paper, we extend ATL with knowledge modalities, of the kind made popular in the work of Fagin, Halpern, Moses, Vardi and colleagues. Combining these knowledge modalities with ATL, it becomes possible to express such properties as group can cooperate to bring about iff it is common knowledge in that . The resulting logic — Alternating-time Temporal Epistemic Logic (ATEL) — shares the tractability of model checking with its ATL parent, and is a succinct and expressive language for reasoning about game-like multiagent systems.     

On Ultrafilter Logic and Special Functions

Logics for generally were introduced for handling assertions with vague notions,such as generally, most, several, etc., by generalized quantifiers, ultrafilter logic being an interesting case. Here, we show that ultrafilter logic can be faithfully embedded into a first-order theory of certain functions, called coherent. We also use generic functions (akin to Skolem functions) to enable elimination of the generalized quantifier. These devices permit using methods for classical first-order logic to reason about consequence in ultrafilter logic.Presented by André Fuhrmann     

"Solar love": Nietzsche,Merleau-Ponty and the fortunes of perception

Both Nietzsche and Merleau-Ponty repudiate the mirror view of perception and embrace what Nietzsche refers to as solar love or creative perception. I argue that Merleau-Ponty thinks of this type of perception primarily in terms of convergence and Nietzsche in terms of divergence. I then show how, contrary to their own emphases, Merleau-Ponty's notion of flesh and Nietzsche's idea of chaos suggest that convergence and divergence are abstractions from an ontologically prior realm of hybrid perceptions. In this realm, each perception is shot through with the others, simultaneously inside and outside one another. The creative tension among these perceptions continually produces new perspectives or voices, that is, a realm whose very being is metamorphosis. Moreover, this realm of hybrid perceptions suggests a political principle that might prove attractive for communities in an age of diversity and cultural hybridity.     

Care and the dynamics of social world

The concept of social world is formulated for the purpose of deepening our understanding of the dynamics of inclusion, exclusion, and care in interpersonal interaction. World is defined as an irreducible subject-object polarity.Social world is the extremely fragile environment within which people meet, and is easily destroyed. With special attention to family and church life, the conditions for maintaining or losing this environment are examined. Three levels of social world are defined. On the highest level, mutual care, rather than shared opinion, is seen as the factor that facilitates the preservation of social world in the face of world-threatening issues.
