Contraceptive use-effectiveness in Mojokerot Regency, Indonesia: a comparison of regular program and special drive acceptors

A follow-up survey of family planning acceptors between April 1971 a nd March 1973 in Mojokerto, the last 4 months of which period marked the initiation of highly productive special acceptor drives in 2/3 of Indonesia, indicates that: 1) IUD acceptors in the regular program and the special drives are highly persistent and successful contraceptors, 2) pill acceptors are less successful than are IUD acceptors, and 3) special drive pill acceptors are significantly less successful than regular program acceptors of the pill. The figures for all-method continuation rates 1 year after acceptance are approximately 90% for IUD acceptors in both regular and special drive programs, 66% for regular program pill acceptors, and 53% for special drive pill acceptors. Pregnancy rates were, conversely, 6% for regular IUD and 8% for special drive IUD acceptors, 16% for regular pill and 25% for special drive pill acceptors. Controlling for demographic factors (number of living children and age at acceptance) and for secular trends did not alter the findings. The differences between regular program and special drive acceptors while not great suggest that special drives recruit acceptors who are more difficult to motivate and might not accept in the regular program. A relatively low percentage of special drive acceptors was lost to follow-up which suggests reported acceptances were in fact real. Sampling was done on a systematic random basis and the Tietze short-form questionnaire was used for data collection. Validity checks were made with indications that response error was low. The performance statistics of IUD acceptors in both types of program compare favorably with median international experience, while regular program pill acceptor performance approximates median international experience, and special program pill acceptance is below the median, though well within the range of international experience.

Some characteristics of the achievement motive in women.

The hypothesis that female Ss would respond to arousal cues with heightened achievement motivation scores and high moitvation performance relationships when the cues were related to a goal that was achievement-relevant to the Ss but not otherwise was advanced to explain hitherto inconsistent experimental results obtained in this area with female Ss. Additional hypotheses stated that both these effects would be greater when female figures were used in the projective measure of motivation except in the case of girls who valued both the goals—intellectual and woman's role—when they were presented with intellectual arousal cues. In this case the effects should be greater when male figures are used. The hypotheses were confirmed except that motivation scores were always higher under intellectual arousal when male figures were used and under woman's role arousal when female figures were used.

SINAMICS—the high efficiency drive technology for rolling mills

In the Metals Industry,interruption-free processes to produce high-quality end products are a prerequisite. The main drives together with the mill stands play a key role in the success of rolling mills.The crucial demands placed on the drive system are:high-dynamic performance of drive and its control system,ability to handle the process related overloads,smooth running,high availability,high efficiency,easy serviceability and ability to integrate seamlessly with the automation systems.With numerous reference installations and many years of experience Siemens VAI has the wider expertise and the portfolio to provide the right drive for every application. This paper examines the latest innovation,SINAMICS drive technology,for both new drive applications as well as for modernizing the existing drives in rolling mill applications like hot strips mills,plate mills,cold rolling mills,and long rolling mills.

Perceptual-cognitive and personality development of Mexican and Anglo-American children as measured by human figure drawings.

Presents longitudinal and cross-sectional human figure drawing data for 394 8.7-17.7 yr old Mexican and American school children. The factors of sex, age, socioeconomic status, culture, and year of repeated testing were investigated in factorial complex analyses of variance for Goodenough-Harris scores in the 1st and 2nd figures drawn and for masculinity-femininity ratings on both sex figures drawn. Percentages of Ss drawing self-sex figures 1st are presented. The importance of cultural variables as determinants of the behaviors involved in performance on these measures was evident from the significant main effects and complex interactions obtained. Cultural differences in rearing practices linked with sex of S were reflected in the poorer degree of sexual differentiation in the drawings of American, as compared with Mexican, Ss. Important methodological and interpretative issues in cross-cultural research and clinical application are discussed (e.g., those involved in employing uniculturally developed instruments with culturally different populations).

Lack of flexibility in visual grouping in patients with schizophrenia.

The study attempted to distinguish automatic grouping processes from top-down processes in a visual perceptual task in 30 patients with schizophrenia and 30 matched controls. Participants decided whether 7 figures were all different or whether 2 adjacent figures were identical. The distance between figures was manipulated to produce 3 separated pairs of figures, the targets belonging to either the same pair (within-group trials) or different pairs (between-groups trials). As controls, patients benefited from proximity for grouping. Top-down processes were explored by manipulating the proportion of within-group and between-groups trials in 3 experimental blocks. In patients, response times (RTs) decreased for within-group trials when within-group trials were more frequent, indicating that performance was correctly adapted to the type of block. Unlike controls, however, this RT decrease was not accompanied by a cost for between-groups trials. Ocular movement recordings revealed that controls were able to focus on between-groups regions selectively when between-groups trials were more frequent, whereas patients were unable to do so. The authors suggest that top-down processes allowing the construction of a selective representation of between-groups regions are impaired in patients with schizophrenia.
