National Educational Longitudinal Survey

Among Mexican Americans, generational differences in education do not fit with assimilation theory’s predictions of significant improvement from the second to third generation; instead, education for third generation remains similar to the second generation and falls behind that of non-Hispanic whites. Scholars have not examined this educational gap for recent cohorts, nor have they considered a wide range of economic outcomes by generation. Using a nationally representative sample of young adults from the National Educational Longitudinal Survey, we examine various educational and economic outcomes among second- and third-generation Mexican Americans and compare it to whites and blacks. We find that third-generation Mexican Americans have similar outcomes to the second generation and lower education and economic levels than whites and blacks, even when controlling for key factors. Our findings reveal limitations to assimilation theory and suggest that the persistent low status of third-generation Mexican Americans may be largely due to their racialization. These findings coupled with prior research on Mexican Americans point to a consistent pattern of third generation disadvantage, which stands in contrast to second generation advantage.

Divergent gender role attitudes among ethnic groups in Britain are thought to contribute to ethnic disparities in many socio-economic domains. Using nationally representative data (2010–2011), we investigate how ethnic minority gender role attitudes vary across generations and with neighborhood ethnic composition. The results show that while Pakistanis, Bangladeshis, Indians, and Black Africans have more traditional attitudes than Black Caribbeans, the attitudes of the former groups are more traditional in the first than in the second generation. We also find that the gender role attitudes of Pakistanis, Bangladeshis, and Indians become more traditional as the local share of co-ethnic neighbors increases or the share of White British residents decreases. Importantly, these patterns are more pronounced for second-generation Pakistanis and Bangladeshis, whose gender role attitudes are more sensitive to variations in neighborhood ethnic composition than are those of the first generation. Taken together, these findings indicate that migration researchers must conceptualize and study how immigrants’ cultural values are heterogeneous, fluid, and dynamic characteristics that can vary spatially across host societies.

First And Second Generation

This chapter provides a brief overview of wireless systems and standards. The evolution of wireless systems from voice-centric circuit-switched systems to data-centric packet-switched systems is discussed. The first- and second-generation wireless systems were designed primarily for voice service. The data rate supported by these systems is very limited. The 2.5G systems were developed to retrofit second-generation systems to support higher data rate applications. The third-generation systems are designed to meet the demands of the Internet era. A wide range of IP-based services is provided using these systems. IEEE 802.16 standard-based systems, commonly referred to as WiMAX, are being proposed as an alternative to third-generation systems for carrying data traffic. Popular wireless LAN and wireless PAN standards are also discussed.

Adsorption Of N2

The porous structure of second- and third-generation polyphenylene-type dendrimers was investigated by adsorption of N2, Ar, and CO2 gases, scanning electron microscopy and small-angle X-ray spectroscopy. Rigid dendrimers in bulk are microporous and demonstrate a molecular sieve effect. When using CO2 as an adsorbate gas, the pore size varies from 0.6 to 0.9 nm. This is most likely due to the distances between dendrimer macromolecules or branches of neighboring dendrimers, whose packing is mostly realized due to intermolecular interactions, in particular, π–π interactions of aromatic fragments. Intermolecular interactions prevent the manifestation of the porosity potential inherent to the molecular 3D structure of third-generation dendrimers, while for the second generation, much higher porosity is observed. The maximum specific surface area for the second-generation dendrimers was 467 m2/g when measured by CO2 adsorption, indicating that shorter branches of these dendrimers do not provide dense packing. This implies that the possible universal method to create porous materials for all kinds of rigid dendrimers is by a placement of bulky substituents in their outer layer.

Regression Decomposition

High school dropout rates among Mexican Americans decline markedly between the first and second immigrant generations and, consequently, move closer to non-Hispanic white levels. However, the third generation makes little progress in closing the remaining gap with whites despite their parents having more schooling on average than those of the second generation. Utilizing 2007–2013 Current Population Survey data, we examine whether an inter-generational shift away from two-parent families contributes to this educational stagnation. We also consider the effect of changes in sibship size. The analysis involves performing a partial regression decomposition of differences between second- and third-generation Mexican-American adolescents (aged 16–17 years) in the likelihood of having dropped out. We find that Mexican third-generation teens are close to nine percentage points less likely than second-generation peers to live with two parents. The decomposition results suggest that this change in family structure offsets a substantial portion of the negative influence of rising parental education on third-generation dropout risk.

AbstractThis paper compares generations (G1, G1.5, G2, G3) of male Turkish migrants to Europe in their transnational behaviours: contact frequency, visits, remittances, property ownership and voting. We aim to explain differences by generational differences in transnational convoy size and integration into residence countries. Data from 798 members of migrant families were obtained from 2000 Families. Generations differ in visiting, remitting, property ownership and voting, but not in contact frequency. Using regression analysis, the transnational convoy cannot explain transnational behaviours. Structural and socio-cultural integration impact various transnational behaviours within generations. Generally, waning of transnational ties across generations cannot be attributed to differences in transnational ties or integration. We add to knowledge on generational differences in transnational behaviour until the third generation and on determinants of transnational behaviour, but conclude that the field of transnational studies is in need of further refinement of operationalization and theory to understand generational differences in transnational behaviour.

Substrate Proteins

Protein O-mannosyltransferases (Pmts) comprise a group of proteins that add mannoses to substrate proteins at the endoplasmic reticulum. This post-translational modification is important for the faithful transfer of nascent glycoproteins throughout the secretory pathway. Most fungi genomes encode three O-mannosyltransferases, usually named Pmt1, Pmt2, and Pmt4. In pathogenic fungi, Pmts, especially Pmt4, are key factors for virulence. Although the importance of Pmts for fungal pathogenesis is well established in a wide range of pathogens, questions remain regarding certain features of Pmts. For example, why does the single deletion of each pmt gene have an asymmetrical impact on host colonization? Here, we analyse the origin of Pmts in fungi and review the most important phenotypes associated with Pmt mutants in pathogenic fungi. Hence, we highlight the enormous relevance of these glycotransferases for fungal pathogenic development.

This study explored the generation gap in American consumers’ green perceptions and purchase intentions across four generations (Gen Z, Y, X, and Baby Boomers) from the perspectives of consumer socialization and social intelligence. Analyzing a nationally representative sample of adults in the United States ( N = 19,450), the survey results revealed that the American consumer’s green norms and beliefs varied by generation. A series of multiple regression analyses showed that each generation had similar but idiosyncratic beliefs in purchasing products from green companies. Theoretical and practical implications are discussed.
