[Sex ratios in Turkey].

"The article [provides] examples of error in the censuses and surveys and questions the reliability of age specific sex ratios in the 1990 Census of Turkey...[and derives] sex ratio at birth from census and survey results as well as from hospital records. Finally the 1990 population is reconstructed by surviving birth cohorts [from] 1900 until 1990 using historical trends of birth rates and cohort, age and time specific survival rates using the East Family of Coale-Demeny Model Life Tables."

[Ethnic structure in Turkey as implied by the analysis of census data on mother tongue].

The authors examine data on language from population censuses conducted in Turkey from 1927 until 1971. "The main objective of this paper is to draw some implications about the ethnic structure of Turkish citizens to the extent permitted by the available 'mother tongue' data. Turkish is the most commonly used language followed by Kurdish and Arabic. Census data carry evidence of differential mortality (as well as fertility) on growth rates of different sub-groups in Turkey. The paper sets 'reasonable' low and high estimates of major groups under different growth rate assumptions in Turkey." (SUMMARY IN ENG)

[Average number of living children of the members of parliament].

"This study compares the average number of living children of the members of the parliament [in Turkey] with the average number of living children of the general public as found in the 1988 Population and Health Survey. The findings indicate that the average number of living children of the members of the parliament [is] substantially lower than that of the general public. Under the light of these findings the members of the parliament are invited not to refrain from speeches promoting family planning in Turkey." (SUMMARY IN ENG)

Transmission delay of phase-locked cells in the medial geniculate body.

Over 4000 single unit recordings were obtained from the medial geniculate body (MGB) of nitrous oxide anaesthetized cats. Out of 1600 cells sensitive to tone bursts below 4 kHz, 10% were responding in a sustained manner. From these, 121 were tested for phase-locked responses. The general characteristics of these units have been described in a previous report. The central tendency of the discharges distribution within the period or mean phase angle was studied for many frequencies in 24 phase-locked units. For each of them, the mean phase angle shifts linearly with the frequency. The slope of these phase versus frequency lines is an accurate measure of the transmission delay from the cochlea to the MGB. This delay is a function of the unit's characteristic frequency and shows that the time spread introduced by the cochlea between the high and low frequency components of an acoustic signal is preserved up to the MGB. Subtracting the cochlear delay from this overall delay, the neural delay from the eighth nerve to the MGB was found to be 6.4 ms for neurons having a CF above 300 Hz; it was greater by 3 ms for cells with a CF below that frequency.

The use of traditional methods of contraception among Turkish couples.

About half the users of contraceptives in Turkey employ traditional methods of family planning, particularly withdrawal. This report presents data from a 1988 national survey to examine Turkish couples' use of and opinions about these methods. Use of traditional methods is widespread across all geographic, demographic, and socioeconomic groups. The principal reasons reported for not using methods generally considered to be highly reliable were fear of health problems and side effects and the opposition of husbands to such methods. Most couples who practice withdrawal also feel that it is as effective as modern methods. These findings imply that a major focus of family planning efforts should be the education of women, of their partners, and of health-care and family planning providers concerning the benefits, risks, and failure rates of both traditional and modern contraceptive methods.
