Folic acid and the prevention of neural tube defects: A position paper of the national society of genetic counselors

Considerable scientific evidence demonstrates the reduction in risk for neural tube defects (NTDs) associated with maternal preconceptional folic acid supplementation. The National Society of Genetic Counselors (NSGC) endorses the U.S. Public Health Service recommendations for folic acid supplementation at the 0.4 mg level for women in the general population and at the 4.0 mg level for women at high or increased risk for NTD pregnancies for at least 4 weeks prior to active pursuit of conception. We encourage targeted educational efforts and surveillance to assess results of this dietary supplementation. The NSGC further urges the Food and Drug Administration to fortify staple foodstuffs with folic acid for a population-based approach to minimize the number of NTD births.     

Selective migration— Still a viable hypothesis

Kamin (1980) has contended that arguments presented in Wolff (1979) are too weak to justify “resuscitating the selective migration debate.” Although Kamin's (1980) critique points up the need for closer scrutiny of the cumulative-deficit phenomenon, it fails to refute Wolff's (1979) conclusion that selective migration is partly responsible for the North-South black IQ differential.     

Are there constraints on childhood disfluency?

Analysis of the spontaneous speech of eight stuttering and eight normally fluent children reveals that (a) the location of both stuttering and normal disfluent moments is constrained by sentential constituent structure, and (b) stuttering children experience fluency breakdown with a particular type of constituent (verb phrase) not usually disfluently produced by normals. A view of early stuttering as a sentence planning and integration disorder is present.     

Right-left confusion in the adult: A verbal labeling effect

Directional judgments are typically slower when relative location is described by the words “east” and “west” or “right” and “left” than when described by the words “north” and “south” or “up” and “down.” A series of experiments are reported that disentangle verbal from perceptual encoding explanations for right-left difficulty. Overall, our results support a verbal encoding explanation for right-left confusion in the adult. Experiments 1-3 demonstrate that in a response-differentiation task, it is response to the labels “north,” “east,” “south,” and “west” that is responsible for right-left confusion. In addition, Experiments 4-6 demonstrate that right-left difficulty in a mirror image discrimination task is contingent on the use of directional labels. (The data also suggest that it may be more difficult to deal with “up,” “down,” “left,” and “right” than with “north,” “south,” “east,” and “west”) The data are interpreted as inconsistent with a bilateral symmetry explanation for right-left confusion.     

On the examination of the role of the episcopalian priest in the pastoral ministry

The purpose of the research was to identify empirically and measurably those dimensions considered important by laity in evaluating their priest. The 83-item questionnaire was developed from existing instruments and from an interview survey carried out on laity from a national selection of Episcopal parishes. 221 parishes responded with complete data. A factor analysis was performed on the data yielding eight useable factors: (a) Pastoral sensitivity, (b) Administrative Skills, (c) Scholarship, (d) Personal Integrity, (e) Innovation, (f) Personal Spirituality, (g) Meaningfulness of Services, and (h) Laity Involvement. The results of the research were seen as a beginning insight into what the laity perceived as important aspects of their parish priest's role, and an instrument to measure these dimensions for further research was produced.     

Sexual activity and contraceptive use among low-income urban black adolescent females.

A modified form of Nathanson and Becker's (1983) Health Belief Model Questionnaire and other measures designed to assess cognitive processing were administered to low-income black adolescent female clients of an inner-city comprehensive health care clinic. The purpose of the study was to explore determinants of sexual activity and contraceptive use. Subjects were classified as not sexually active (n = 50), sexually active/noncontracepting (n = 20), or sexually active/contracepting (n = 72). Not sexually active subjects tended to be younger, more career motivated, to have a father at home, to be more influenced by family values, and to have more conservative attitudes regarding adolescent sexuality than did sexually active subjects. Sexually active/noncontracepting subjects tended to report fewer benefits and more barriers to the use of contraception. Level of cognitive processing did not differ among the three groups, but was at a lower-than-expected level for age. Finally, inconsistent contraceptive use was common to both sexually active groups.     

Mental imagery and dyslexia: a deficit in processing multipart visual objects?

Dyslexic and normal control subjects memorized simple line patterns inside a grid and subsequently judged whether an "X" would have fallen on the pattern had it been present in an empty grid. The patterns were letters and novel shapes. The grids were presented to the left visual field, to the right visual field, or in central vision. Dyslexic subjects had difficulty generating images of multipart patterns, but this deficit was limited to letters. The findings suggest that dyslexics may have selective difficulty integrating visual information stored in long-term memory.     

Central issue importance as a function of gender and ethnicity

A recent theoretical model of centrality (Bernstein, 1987; Bernstein, Hofmann, Santiago, & Diebolt, 1989) suggests that the importance attached to certain “central issues” may increase the vulnerability of individuals to distress and depression, and may explain the differential rates of depression among gender, racial, and ethnic groups. The present study was designed to examine the importance of central issues as reported by Anglo, Black, and Hispanic men and women (N=169). Multivariate analyses revealed significant gender, ethnicity, and gender X ethnicity effects. Specifically, women considered Intimacy significantly more important than did men, whereas men attached more importance than women to Affiliation. Anglos rated Achievement significantly higher than did Hispanics and Blacks; Hispanics considered Affiliation more important than the other two groups; and Blacks considered Intimacy the least important among the groups. Moreover, Hispanic men attributed significantly greater importance to Change, Adventure, and Control, whereas Hispanic women attached the least significance among all the groups to Control. The results are discussed in terms of cultural influences on sex role orientation and central issues, and the process by which culture and ethnicity may be related to vulnerability to depression and distress.     

Factorial validity and reliability of the Devereux Elementary School Behavior Rating Scale

The factorial validity and internal consistency reliability of the Devereux Elementary School Behavior Rating Scale was examined using a random sample of elementary-school children in grades I through 6. Teacher ratings of subjects' classroom behaviors on the Devereux approximated ratings obtained by the standardization sample. Internal consistency (coefficient alpha) reliability coefficients of the 11 Devereux subscales were found to be quite adequate, ranging from 80 to 93. Intercorrelations among Devereux subscales were moderate to high. A principal factor analysis of the 11 subscales produced two factors with eigenvalues greater than 1.0, which cumulatively accounted for 70.2% of the total variance. When rotated via an orthogonal (Varimax) solution, the two resultant factors appeared to measure emotional adjustment and academic related dimensions of classroom behavior. Given the problem of multicollinearity that was shown to exist among subscales, the authors suggest caution in the interpretation of Devereux subscales as discrete factors.The authors gratefully acknowledge computer support funding provided by the University of Wisconsin, Graduate School Research Committee Grant 135-1537 to the first author.
