Interannual fluctuations in recruitment and growth of the sardine,Sardinops melanostictus, in the sea of Japan and adjacent waters

Recruitment and growth of the sardineSardinops melanostictus fluctuated markedly in the Sea of Japan and adjacent waters between 1978 and 1993. Stock size was calculated using Virtual Population Analysis and average body length in each age class was determined by the number of annual rings on the scales. There is an inverse correlation between average water temperature at a depth of 50 m in the coastal area of the mainland of Japan in winter (January to March) and recruitmentR defined as the number of individuals at 1 year old. There is also an inverse correlation between spawning stock sizeE and reproductive success in (R/E). A multiple regression model using spawning stock size and water temperature in winter as independent variables can explain 73% of variance in reproductive success. It suggests that both density-dependent and density-independent factors perform important roles determining reproductive success. There is an inverse correlation between body length and stock size and this suggests that there is a density-dependent effect on the growth of the sardine.     

The Persistence of Racial Disadvantage: The Socioeconomic Attainments of Single-Race and Multi-Race Native Americans

Using data from the 2000 U.S. Census, we investigate the schooling and earnings of single-race and multi-race Native Americans. Our analysis distinguishes between Single-Race Native Americans, biracial White Native Americans, biracial Hispanic-White Native Americans, and biracial Black Native Americans. Further differentiating by gender, the results indicate significant variation in socioeconomic attainments across these different Native American groups although almost all of them are in some way disadvantaged relative to non-Hispanic, non-Native American whites. The most disadvantaged group tends to be Single-Race Native Americans who have the lowest levels of schooling as well as lower earnings relative to non-Hispanic, non-Native American whites who are comparable in terms of schooling, age, and other basic demographic characteristics. The results demonstrate notable differentials by the racial/ethnic type of Native American group as well as by gender. In the case of men, all of the Native American groups have clear socioeconomic disadvantages. One contrast is that migration slightly increases the earnings of men but it slightly decreases the earnings of women. We interpret these findings as underscoring how measured socioeconomic differentials between demographic groups are significantly affected by the categorization of race/ethnicity in surveys and by how persons choose to be enumerated in terms of those categories.     

The Socioeconomic Attainments of Non-immigrant Cambodian, Filipino, Hmong, Laotian, Thai, and Vietnamese Americans

Using recent American Community Survey data, this study investigates socioeconomic attainments of six ethnic groups of Southeast Asian Americans. Findings show that the educational attainment of Filipinos, Vietnamese, and Thai is higher than that of whites, while the educational attainment of Cambodians, Hmong, and Laotians is lower than that of whites. Regarding earnings, Southeast Asian American women are generally not disadvantaged relative to white women, but Southeast Asian American men tend to have lower earnings than white men after controlling for education and other demographic factors such as age, metropolitan residence, and region. We conclude that Cambodians, Hmong, and Laotians are the most disadvantaged groups among Southeast Asian Americans and that most Southeast Asian American male groups tend to be at least slightly disadvantaged in the labor market at least after controlling for metropolitan residence and region.     

Difference in Eye Gaze for Floor Apportionment in Native- and Second-Language Conversations

In face-to-face communication, eye gaze is known to play various roles such as managing the attention of interlocutors, expressing intimacy, exercising social control, highlighting particular speech content, and coordinating floor apportionment. For second language (L2) communication, one’s perception of eye gaze is expected to have more importance than for native language (L1) because eye gaze is assumed to partially compensate for the deficiencies of verbal expressions. This paper examines and clarifies the efficiency of the function of eye gaze in the coordination of floor apportionment through quantitative analyses of eye gaze during three-party conversations in L1 and L2. Specifically, the authors conducted ANOVA tests on the eye-gaze statistics of a speaker and two listeners during utterances while focusing on whether floor-switch occurs subsequent to the utterance. The analysis results show that the listener who is gazed at more by the speaker is more likely to be the next speaker with a higher probability in L2 than in L1 conversations. Meanwhile, the listeners gaze more at the speaker in L2 than in L1 conversation for both the utterances just before a floor switch and cases with no floor switch. These results support the observation that the eye gaze of the speaker is efficient for floor apportionment in L2 conversations and suggest that longer listeners’ eye gazes in L2 conversations also function efficiently in smooth floor apportionment.     

Cultural constraints on rising income inequality: A U.S.–Japan comparison

Prior research has identified fundamental cultural and normative concepts—including wa, enryo, giri, and amae—that are typically argued to be integral to Japanese society. We advance this line of research by discussing how these traditional cultural concepts may influence labor market relations and thereby constrain the degree of income inequality in Japan relative to the U.S. Collectivist cultural attitudes are embedded in Japanese work organization, and are naturally inherited social constraints when compared to more unbridled labor market relations of the “New Economy” in the U.S. While studies of rising inequality in the U.S. and Europe consider how governmental policies impinge upon market forces in order to moderate labor market outcomes, our analysis suggests how culture may sometimes directly constrain income inequality without imposing legal regulations or instituting official programs.     

Demographic Factors Associated with Poverty among American Indians and Alaska Natives

Using data from the American Community Survey for the period 2006–2010, this study provides up-to-date demographic information about poverty among American Indians and Alaska Natives. Our analysis investigates both absolute poverty and relative poverty and distinguishes between four racial categories of American Indians and Alaska Natives including single-race American Indian; biracial white and American Indian; biracial black and American Indian; and other multirace American Indian. We also report results for thirty-seven of the largest self-reported tribal affiliations for single-race American Indians. In general, all of the American Indian and Alaska Native groups have higher levels of absolute and relative poverty rates compared to non-Hispanic whites. The problematic character of poverty among American Indian racial groups is underscored by their substantially higher odds of being poor (relative to non-Hispanic whites), even after statistically taking into account age, gender, education, metropolitan status, and region of residence. Significant variation across the thirty-seven tribal groups is evident, however, with single-race American Indians having the highest level of poverty. This variability suggests the need for future research into the various tribal affiliations and tribal economies.
