Evaluating the Impact of a National AIDS Prevention Radio Campaign in St. Vincent and the Grenadines1

Based on extensive formative research in the three Eastern Caribbean countries of St. Lucia, St. Vincent and the Grenadines, and Grenada (Fishbein, Middlestadt, & Trafimow, 1993; Fishbein, Trafimow, et al., 1993), a three-nation, mass media, condom use campaign was developed. In order to assess the impact of the campaign, a follow-up survey was conducted in St. Vincent and the Grenadines. This paper examines the effectiveness of the campaign by comparing responses on this survey by respondents who were or were not exposed to the campaign. A statistically significant impact of exposure to the campaign was obtained, indicating that a well-designed, empirically based, mass media campaign can be an effective tool in the battle to prevent the spread of AIDS.     

Defiant spirituality: Care traditions in the black churches

Conclusion I have tried to demonstrate that black church defiant spirituality is a complex, multi-dimensional phenomenon. In essence it represents the quest of exiled African peoples to experience ontological harmony with God and all of creation. In the context of a racist society, it has adapted itself to the exigencies of survival and gradual liberation. Specifically, it has sought to reconstruct reality by religiously affirming God's sovereignty over the just and unjust. Also, it has negated black invisibility, subverted political anemia, and now struggles to resist and conquer an encroaching spiritual despair in post-industrial society.I have identified three basic treasures which the black church may offer to other cultures, namely, that care and discipline are the responsibility of every Christian, that authentic Christian worship nurtures commitments to individual and social transformation and it offers a full sensory experience. I close with words from one of America's greatest twentieth century poets, Langston Hughes (1974)—entitled Mother to Son: Well, son, I'll tell you: Life for me ain't been no crystal stair. It's had tacks in it, And splinters, And boards torn up, And places with no carpet on the floor—Bare. But all the time I'se been a-climbin' on, And reachra' landin's, And turnin' corners, And sometimes goin' in the dark Where there ain't been no light. So boy, don't you turn back. Don't you set down on the steps 'Cause you finds it's kinder hard. Don't you fall now —For I'se still goin', honey, I'se still climbin', And life for me ain't been no crystal stair. (p. 187)     

Internal approach to external sets and universes

A problem which enthusiasts ofIST, Nelson's internal set theory, usually face is how to treat external sets in the internal universe which does not contain them directly. To solve this problem, we considerBST,bounded set theory, a modification ofIST which is, briefly, a theory for the family of thoseIST sets which are members of standard sets.We show thatBST is strong enough to incorporate external sets in the internal universe in a way sufficient to develop the most advanced applications of nonstandard methods. In particular, we define inBST an enlargement of theBST universe which satisfies the axioms ofHST, an external theory close to a theory introduced by Hrbaek. HST includes Replacement and Saturation for all formulas but contradicts the Power Set and Choice axioms (either of them is incompatible with Replacement plus Saturation), therefore to get an external universe which satisfies all ofZFC minus Regularity one has to pay by a restriction of Saturation. We prove thatHST admits a system of subuniverses which modelZFC (minus Regularity but with Power Set and Choice) and Saturation in a form restricted by a fixed but arbitrary standard cardinal.Thus the proposed system of set theoretic foundations for nonstandard mathematics, based on the simple and natural axioms of the internal theoryBST, provides the treatment of external sets sufficient to carry out elaborate external constructions.Partially supported by AMS grants in 1993 and 1994 and DFG grant in 1994.Presented byRobert Goldblatt     

Internal approach to external sets and universes

In this article we show how the universe ofBST,bounded set theory (a modification ofIST which is, briefly, a theory for the family of those sets inIST which are members of standard sets) can be enlarged by definable subclasses of sets (which are not necessarily sest in internal theories likeBST orIST) so that Separation and Replacement are true in the enlargement for all formulas, including those in which the standardness predicate may occur.ThusBST is strong enough to incorporate external sets in the internal universe in a way sufficient to develop topics in nonstandard analysis inaccessible in the framework of a purely internal approach, such as Loeb measures.Presented byRobert Goldblatt

Me,us and them: Political identification and the third-person effect in the 1993 Australian federal election

Three days prior to the 1993 Australian federal election 54 Australian university students who identified with one of the two major political parties were surveyed regarding their perceptions of media campaign impact on self and others. Results provided evidence of a third-person effect (Davison, 1983) wherein respondents judged others us more influenced by the election campaign than themselves. Consistent with predictions derived from social identity theory and self-categorization theory (e.g. Turner, Hogg, Oakes, Reicher and Wetherell, 1987), political ingroup members were also judged as less injuenced by campaign content than political outgroup members. Respondents who identified strongly with their preferred party judged self and ingroup members as less influenced by campaign content than did other respondents, and showed more evidence of positive intergroup differentiation. At the same time, however, these respondents exaggerated self–ingroup differences, challenging the theoretical assumption that intergroup diferentiation is associated with ingroup assimilation. Judgements of media impact on self and other also depended on the direction of the campaign message. Respondents believed ‘voters in general’ were persuaded in line with the intent of campaign content, while outgroup members were seen to be persuaded by material favouring their own side but to be uninfluenced by counter-attitudinal content. Election propaganda, irrespective of direction, was seen to amplify existing party preferences in self and ingroup members. Hence the relative invulnerability of self to media impact was pronounced when respondents judged the impact of pro-outgroup messages. Results suggest that perceptions of self–other differences in media vulnerability are influenced by the subjectively salient social relationship between self and other, and are governed by motivational needs, such as self-esteem, social-identity, and differentiation from others (cf. Brewer, 1991; Hogs and Abrams, 1993).     

Tropic implicature and context in the comprehension of idiomatic phrases

Research concerned with how people understand idiomatic expressions has focused primarily on lexicalization, familiarity or literalness. In contrast, this study examined the extent to which comprehending idiomatic phrases in context depends upon the words which make up such phrases. Using reading time as a dependent measure and by substituting idiomatic expressions with phrases which retain the equivalent semantic meaning in context, the role of familiarity and literalness were again investigated. The results lend support to the importance of familiarity in comprehending idiomatic expressions (Schweigert, 1991); however, they raise questions about the extent to which idiomatic phrases are syntactically frozen. The findings provide a platform for considering contemporary theories of idiomatic comprehension and related theories of meaning.     

Biased attention in childhood Anxiety disorders: A preliminary study

This study provides preliminary tests of two hypotheses: (1) Anxiety-disordered children show an attentional bias toward emotionally threatening stimuli, and (2) normal controls show an attentional bias away from emotionally threatening stimuli. Twelve children, 9 to 14 years of age, with primary diagnoses of anxiety disorder were compared with 12 normal controls matched for age, gender, vocabulary level, and reading ability. Subjects completed a reaction time task that measured visual attention toward threatening versus neutral words. The anxious group showed the predicted attentional bias toward threat words. However, controls did not show the predicted bias away from threat words. These results are the first showing that biased attentional processing occurs among clinically anxious children. The potential role of such an attentional bias in childhood anxiety disorders and future direction for research are discussed.This research was supported by a Seed Grant and a Small Grant to the first author from The Ohio State University. Portions of this paper were presented at the 27th Annual Convention of the Association for the Advancement of Behavior Therapy, Atlanta, November 1993.

Crisis Intervention With Survivors of Natural Disaster: Lessons From Hurricane Andrew

Crisis intervention has typically been conceptualized as seeking a return of clients to a state of equilibrium. Our work with Hurricane Andrew survivors in south Florida, as part of the Disaster Mental Health Services team of the American Red Cross, has led us to appreciate the importance of several further considerations. In our work, we developed a proactive approach, attempting to recognize and extend clients' preexisting strengths. We offer a number of pragmatic interventions, focusing particularly on children's issues and we draw attention to sensitive multicultural issues.
