Two trends in middle-class birth in the United States

This discussion focuses on two important trends in American childbirth that have emerged in the past 30 years, the demand for a perfect baby and the desire for a perfect birth. These two trends are particularly important in the subgroup of middle-class women who have decided on delayed childbearing. Tremendous technological innovations, such as ultra-sound, prenatal genetic analysis, and fetal monitoring, have promoted the perception that physicians can control the prenatal environment and predict the pregnancy outcome. This expectation may lead to bitterness and anger in the event of an adverse pregnancy outcome. In contrast, women and their families have also come to desire more control over the birth experience. If the parents’ birth plan is not achieved and their expectations not fulfilled, many parents feel they have not performed well. When the physician acts as a guide in the birth process, parents and physicians together may transcend the conflict to achieve a more satisfactory birth experience.     

Estimation of animal intelligence by university students in Japan and the United States

Abstract

Japanese and American university students rated the intelligence of 56 animals relative to that of humans. In general, American students (n=104) rated animal intelligence higher than did Japanese students (n=235), and females rated intelligence higher than did males. In spite of these differences among groups, the general patterns of ratings were almost identical: The correlation coefficients of the male–female comparisons were 0.99 in both countries, and the coefficients of Japan–US comparisons in male and female groups were 0.95 and 0.96, respectively The intelligence ratings generally corresponded to the so-called “phylogenetic scale” from amoeba to chimpanzee, with several exceptions. The implications of these findings for the cross-cultural analysis of perceptions of animal mentality are discussed.     

Social Support in Two Cultures: Everyday Transactions in the U.S. and Empathic Assurance in Japan

We studied received social support using the cross-cultural method of situation sampling. College students from the US and Japan described and rated recent examples of received social support, both everyday support as well as support in response to stress. Middle class, European-American (EuA) students’ situations fit a model in which support is frequent and offered freely in interactions, even for relatively minor issues. Even when it’s unrequested, EuA support makes recipients feel in control, and support-givers are perceived to have acted by free choice. In contrast, results suggest that middle-class Japanese (Jpn) contexts favor support that is empathic and responsive to the recipients’ degree of need. Japanese support was experienced positively when it was emotional support, when it was in more serious situations and when the support was rated as needed by the recipient. In Japan, although problem-based support is most common, it is not particularly positive, apparently because it is less likely to be perceived as needed.     

Comparison of osteoporosis and calcium intake between Japan and the United States.

The number of osteoporotic females in Japan with vertebral bone mineral density measured by dual energy x-ray absorptiometry, defined as less than -3 SD of the peak bone mass, is approximately 10,000,000, corresponding to 8% of the whole population of Japan. While this value approximately corresponds to the prevalence of low bone mineral density in the United States, the incidence of hip fracture appears to be much less in Japan than in the United States, 50,000 per 125,000,000 per year compared with 250,000 for a population twice as large. This seems to be paradoxical because of the lower bone mineral density and lower calcium intake in Japan, with 400-500 mg/day mainly as soybean products, small fish with bones, and vegetables. The difference in hip fracture incidence, however, may not actually be as wide as it seems when the larger number of bedridden elderly subjects in Japan is taken into consideration. In these bedridden subjects with severe immobilization osteoporosis, hip fracture is only prevented by the fact that they are not ambulatory. Life-style difference may also offer an explanation. Sitting on a tatami mattress on completely flexed knees with frequent standing up, along with other household work, in a narrow home space may ensure a marked development of hip musculature and also provide skill in balancing oneself to prevent fails. The difference in fracture incidence should be analyzed from various angles to obtain a firm ground for the future prevention of hip fracture due to osteoporosis. Although osteoporosis universally affects all races and nationalities, conspicuous differences may be encountered in the severity of its manifestations and complications.(ABSTRACT TRUNCATED AT 250 WORDS)

Geomicrobiological Changes in Two Ephemeral Desert Playa Lakes in the Western United States

The geochemistry and microbiology of two ephemeral playa lakes in the Western United States, Surprise Valley Alkali Lake (SVAL) and Eldorado Playa (EP), were examined over one wetting cycle, revealing dramatic temporal changes in suspended mineralogy, aqueous chemistry, and bacterial populations. In SVAL the predominant suspended mineral changed from smectite to vermiculite and clinoptilolite, which led to a depletion of soluble Mg²⁺. Nitrate became depleted in both playas as a result of biological nitrogen demand imparted by unusually dense microbial communities reaching ～1 × 10⁸ cultivable heterotrophs per ml of water. One hundred eighty eight bacterial isolates were obtained, representing sixty phylotypes and four phyla: Actinobacteria, Bacteroidetes, Proteobacteria, and Firmicutes. Phylogenetic analyses suggested that the microbial communities reflected different phases of succession, with SVAL changing from a diverse community with abundant Yonghaparkia to a less diverse late summer community with abundant Bacteroidetes and Proteobacteria such as Loktanella, Rhodobaca, Saccharospirillum, Flexibacter, and phylogenetically novel members of the Flexibacteriaceae. In EP, a diverse assemblage of bacteria often associated with soils was replaced very quickly by a much less even community dominated by Yonghaparkia, Sandarakinorhabdus, and relatives of Belliella baltica. Strikingly, the early summer microbial community from SVAL was not significantly different from the EP community that developed within one week of flooding, even though these playas are almost 1000 km apart, whereas sympatric communities in different phases of succession were different. To our knowledge, this is one of the first geomicrobiological studies of a recharge playa, the dominant playa type worldwide.
