Hyperalgebraic primitive elements for relational algebraic and topological algebraic models

Using nonstandard methods, we generalize the notion of an algebraic primitive element to that of an hyperalgebraic primitive element, and show that under mild restrictions, such elements can be found infinitesimally close to any given element of a topological field.Presented by Robert Goldblatt     

Panic attacks without fear: An overview*

‘Non-fearful panic disorder’ (NFPD) is a condition that meets DSM III-R criteria for panic disorder but lacks a report of subjective fear or anxiety. Presenting the first comprehensive overview of this issue, the authors describe studies investigating a wide range of apparently overlapping phenomena including NFPD, ‘somatically expressed panic’, ‘non-cognitive panic’, ‘alexithymic panic’, ‘non-clinical panic’, and ‘masked anxiety’. The review shows that such conditions account for from 20 to 40% of the panic disorder found in various medical populations, and that this group resembles conventional panic disorder in cross-sectional comparisons. We emphasize that a ‘triple-response’ model of anxiety is consistent with our conclusion that NFPD should be conceptualized as a panic disorder subtype. Finally, we discuss unresolved issues regarding the construct and predictive diagnostic validity of NFPD.     

Social desirability in the bedroom: Role of approval motivation in sexual relationships

One-hundred and twelve unmarried participants completed a questionnaire that examined the relationship between gender and approval motivation (assessed by the Marlowe—Crowne Social Desirability Scale) and college students' stereotypes of and experiences with power in sexual encounters. Regardless of approval motivation, students described men as using power predominantly to have sex and women as using power predominantly to avoid having sex. However, interactions between need for approval and gender suggested that high-need-approval women might be having more experiences with sex and power in the bedroom than high-need-approval men. These results are discussed in light of Elkind's hypothesis that adolescent behavior conforms to an imaginary audience of peers and the Crowne-Marlowe model of approval motivation.An earlier version of this article was presented in the symposium Gender and Power Strategies: Contrasting Models and Applications, at the meeting of the American Psychological Association, Los Angeles, August 24–28, 1981. The authors wish to express appreciation to J. W. McCormick for his assistance with data analysis and to E. Allgeier for her helpful comments on a previous draft.     

Adolescents' values, sexuality, and contraception in a rural New York county

75 male and 88 female high school students in a rural county of New York completed a questionnaire asking about personal values and sexual experiences. Religiosity was not likely to affect the incidence of intercourse or effectiveness of contraceptive use. Students with more liberal premarital sexual and profeminist standards usually became more sexually intimate with their dates than did conservative students, but these standards did not predict coital frequency or effective contraceptive use. Different groups exhibited remarkably homogeneous sexual and contraceptive behavior. Nonvirgins had coitus sporadically or on the average of only twice a month. In addition, regardless of their values, most nonvirgins were contraceptive risk takers, partly for fear of interfering with pleasure, and partly because sporadic sex was not perceived by the adolescents to be risky. Rejecting the most, reliable methods available (e.g. birth control pills and IUDs), the condom was the most effective contraceptive used by the majority (57%) and 21% of the nonvirgins relied exclusively on such ineffective contraceptives as withdrawal, trusting in luck, and douching. Younger adolescents may be at particular risk, being more impulse motivated and egocentric, and less likely to seek adult-furnished family planning, especially in a rural community where anonymity is more difficult to protect. Given the uniformity of contraceptive behavior among younger adolescents, and the increasing likelihood of contraceptive use with increasing age of 1st coitus, future study will be needed on the impact of cognitive and emotional maturity, as well as that of environment and family planning resources on young adolescents' contraceptive use.     

Prevalence,dynamic risk factors and the efficacy of primary interventions for adolescent dating violence: An international review

Adolescent dating violence is a pressing international issue: yet, there have been few attempts to collate the international evidence regarding this phenomenon. This article reviews contemporary evidence from Europe and North America on prevalence, dynamic risk factors, and the efficacy of intervention programs for adolescent dating violence. Prevalence findings suggest that victimization rates are comparable across Europe and North America. Although individual studies report differing prevalences, the overall hierarchy of violence types – in which psychological/emotional violence is most and sexual violence least prevalent – is consistent across almost all investigations. Four dynamic risk factors for perpetration are identified: peer influence, substance use, psychological adjustment and competencies, and attitudes towards violence. Peer influences and attitudes towards violence appear to be the most extensively evidenced factors in the literature. Nine existing intervention programs are identified, all located within North America. Intervention results are mixed, with some evaluations reporting significant long-term benefits while others report positive intervention effects dissipate throughout follow-up. Tentative analysis suggests that programs focused on behavioral change may elicit sustainable effects more readily. However, this is difficult to ascertain with no data on program repetitions and variations across intervention pedagogy and sample. Concerns with existing research and interventions and possible future directions are discussed.
