The Effects of Social Trust and Institutional Trust on Formal Volunteering and Charitable Giving in Japan

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.     

Locally best invariant test for outliers in a gamma type distribution

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.     

Neighborhood Association Participation and Formal Volunteering in Japan

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.     

Dynamics of Spanish-Language Neighborhoods in Chicago and Atlanta: 1990–2000

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.     

Life tables for worker honeybees

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.

Overwintering ecology of two social halictine bees,Lasioglossum duplex andL. problematicum

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%).

An Assessment of Alternative Measures of Time Use

Although time use has received much attention by social scientists as an index of resource allocation and social relations across groups, only a few studies have carefully assessed the relative strengths and weaknesses of the existing methods of measuring time use: time diary (TD), stylized (S) respondent report, and experiential sampling method (ESM). We note the varying degree of biases that arise in part from the extent of detail in the information collected by the three methods. Using findings from our analysis of the structure of these methods, we hypothesize that there are empirical exceptions to previously reported common findings that TD provides less biased information on time use than does S—namely (a) when labor market workers report their time spent on labor market work, and (b) when the historical trend in time, rather than the absolute level, is studied. Empirical results confirm our prediction and show that, among individuals who work regularly, TD and S estimates of labor market work hours reported by the same persons correspond closely to one another. In addition, when assessing historical trends, TD and S values correspond closely to one another, although TDs yield some inexplicable deviations from the trend even when the sample and the codes are carefully standardized. We also provide notes on a strategy of standardization for diary codes that are distinct across historical or national contexts.     

How Changes in Sending Countries Influenced Patterns of Interracial Families Through Intercountry Adoption

The racial characteristics of children adopted from abroad by American parents have fluctuated sharply over time in response to changing legislation and attitudes toward intercountry adoptions in the United States and the sending countries. This study investigates how the likelihood of parents adopting a White versus non-White child varies by the characteristics of the adopted child, the parents, and the household. Our analyses, using the 2008–2012 American Community Survey, show that parents consider the child's age, sex, and health; the presence of adopted and biologically related children in the household; and shifts in the availability of children across major sending countries.
