We examine the effect of participation in neighborhood association (NHA) activities on volunteering using the 2010 Japanese General Social Survey data. We find that controlling for established predictors of formal volunteering such as demographic and socioeconomic variables, NHA association participation, either operationalized as a dichotomous or interval variable, positively predicts volunteering. Moreover, some of the established predictors of volunteering (e.g., marital status and associational membership) are useful in predicting NHA participation. Our results indicate a complementary relationship between volunteering and NHA participation. We discuss implications of our study for future research on community volunteering in Japan and elsewhere. 相似文献

This study examines and compares how the spatial arrangements of Spanish speakers have changed over time in a traditional immigrant gateway, Chicago, and in an emerging immigrant gateway, Atlanta. Using the 1990 and 2000 U.S. Census data, spatial autocorrelation analysis confirms that Spanish-language neighborhoods continue to be in the city and the suburbs of Chicago. Atlanta’s Spanish-language neighborhoods, on the other hand, are mainly located in the suburbs where major growth took place over the decade. However, Spanish-language neighborhoods in both the city and suburbs of Atlanta and Chicago share similar characteristics: higher percentages of residents who are foreign-born and limited English proficient, and households with low levels of income. While the model of spatial assimilation is still relevant to our understanding of residential patterns among contemporary immigrants and their descendants, the interpretation of findings, including those for new destinations such as Atlanta where large-scale immigration occurred after suburbanization, should place less emphasis on the central city/suburb distinction and suburban homogeneity. The growing diversity in language use among residents necessitates the provision of accessible social services and information. 相似文献

Using an ordered logit model on representative survey data, we study attitudes about who should provide for the livelihood of the elderly in two aging societies—Germany and Japan. We find that in both countries, those with higher income are more inclined toward the private option, whereas age has the opposite effect. Part-time work status negatively (positively) affects the inclination toward a government-based pension system in Japan (Germany). Other significant influences are the pensioner status of the respondents in Japan and specific left-wing party support in the case of Germans. 相似文献

This study is part of the growing literature on the effects on civic engagement of attitudinal predictors, such as trust, along with structural predictors. Drawing data from the 2005 Japanese General Social Survey, it examines the association between trust and the probabilities of formal volunteering and charitable giving. A bivariate probit analysis of the data suggests that trust, institutional trust in particular, matters more to predict giving than volunteering. Although the number of membership affiliations is positively and significantly associated with both types of civic engagement, the association between membership affiliations and formal volunteering is significantly greater. Implications of these and other findings are discussed for future studies linking trust to civic engagement in group-collectivist societies such as Japan. 相似文献

It is shown that the locally best invariant test for the existence of outliers for scale parameters of the gamma distribution is given by Bartholomew's test for exponentiality which is the ratio of the sum of squares of the data to the square of the sample mean. The optimality robustness, including null and nonnull robustness of the test is shown. A small simulation study to compare the power among the other eight competitive tests for testing exponentiality is performed. It is seen that the locally best invariant test is not always best but is reasonably good. It is slightly better than Cochran's test and suffers less from the limiting masking effect. 相似文献

Summary Life tables for worker honeybees covering all life span, and those for adults, were prepared for three seasonal cohorts,June bees, July bees andwintering bees. Survivorship curves forJune andJuly bees show a convex type being exceptional for insects, with relatively high mortality at egg and feeding larval stages and at
later adult stage after most bees became potential foragers. Adult longevity greatly lengthens inWinteriing bees and survivorship curve drops approximately with the same rate. A remarkable similarity of survivorship curves for men and
honeybees was demonstrated, apparently due to highly developed social care in both. Some comments were given on mortality
factors. The importance of life tables for population researches was shown by applying our result to the population growth
curve made byBodenheimer, based upon the data byNolan. At the asymptote of the uncorrected curve, the ratio of total population estimated by uncorrected curve to that by corrected
curve reaches about 3∶2.

Background
Decreased fetal movements are associated with adverse perinatal outcomes, including stillbirth. Delayed maternal visits to a health care provider after perceiving decreased fetal movements are frequently observed in stillbirths. Informing pregnant women of the normal range of fetal movement frequency is essential in their earlier visits in order to prevent stillbirth.Aim
To investigate the fetal movement frequency in late pregnancy and the effects of associated perinatal factors.Methods
This prospective multicenter study was conducted in 20 obstetric facilities in our region of Japan. A total of 2337 pregnant women were asked to record the time it took to perceive 10 fetal movements by the modified ‘count to 10’ method every day from 34 weeks of gestation until delivery.Findings
The 90th percentile of the time for the maternal perception of 10 fetal movements was 18–29 min, with a gradually increasing trend toward the end of pregnancy. The numbers of both pregnant women giving birth after 39 weeks’ gestation and infants with a birth weight exceeding 3000 g were significantly higher in mothers who took ≥30 min to count 10 fetal movements than in those who took <30 min.Conclusion
The maternal perception time of fetal movements shows a gradually increasing trend within 30 min for 10 fetal movements by the modified ‘count to 10’ method. Informing pregnant women of the normal range of the fetal movement count time will help improve the maternal recognition of decreased fetal movements, which might prevent fetal death in late pregnancy. 相似文献9.

Summary Overwintering of two social halictine bees,Lasioglossum duplex (Dalla Torre) andL. problematicum (Blüthgen), was studied. InL. duplex many females stay near the old nests, each female preparing a hibernaculum separated from the natal nest. InL. problematicum most females overwinter communally within the natal nest. This difference in overwintering habits relates to the social structure
in the next spring.L. duplex is nearly always solitary in spring although later becoming eusocial, whereas many nests ofL. problematicum are polygynous, beginning in early spring.L. duplex overwinters much deeper (
) in the soil than doesL. problematicum (
), but both species are safe from drops in soil temperature, which is above 0°C even in midwinter, and the bees' supercooling
points are lower than −6°C. This cold resistance and the storage of sufficient food in the crop are reflected in the winter
survival, which is much higher (79%) than the rate of successful nests in the spring active phase (25%).
