Ethnic identity and psychological adjustment in transracial adoptees: a review of the literature

International adoption is a relatively recent phenomenon and research in this field is emerging, particularly on issues of ethnic identity development and its implications for psychological adjustment and well-being. This article presents a critical review of the literature on ethnic identity in transracial adoptees as it relates to discrimination and psychological well-being. The review results show no clear evidence on the relation between a strong ethnic identity of origin, racial socialization efforts by parents and psychological adjustment in transracial adoptees. Studies investigating the effects of discrimination are too scarce to be conclusive. Results are discussed in light of future research and clinical recommendations.     

Latino racial choices: the effects of skin colour and discrimination on Latinos’ and Latinas’ racial self-identifications

Abstract

Are predictions that Hispanics will make up 25 per cent of the US population in 2050 reliable? The authors of this paper argue that these and other predictions are problematic insofar as they do not account for the volatile nature of Latino racial and ethnic identifications. In this light, the authors propose a theoretical framework that can be used to predict Latinos’ and Latinas’ racial choices. This framework is tested using two distinct datasets – the 1989 Latino National Political Survey and the 2002 National Survey of Latinos. The results from the analyses of both of these surveys lend credence to the authors’ claims that Latinas’ and Latinos’ skin colour and experiences of discrimination affect whether people from Latin America and their descendants who live in the US will choose to identify racially as black, white or Latina/o.     

Negative incorporation,the next generation and involvement in transnational organizations

ABSTRACT

Can the negative aspects of incorporation – discrimination, marginalization, and frustration with life in a country of settlement – help us to understand next generation transnationalism? This question is applied to a small, non-representative sample of next generation individuals involved in Mexican and Salvadoran transnational political and philanthropic organizations operating in California and Washington, DC. The findings suggest that negative incorporation had some explanatory potential for the transnational mobilization of some respondents. However, the study also suggests the multiple trajectories and contexts that give rise to next generation transnationalism. Involvement in cross-border organizations appears not only to be a refuge for those who perceive the country of settlement negatively or a means through which individuals can respond to negative experiences; it can also be pursued by individuals that positively identify with the country of settlement and perceive its values favourably, indicating the need for a more synthetic understanding of this phenomenon.     

Dry land drowning or rip current survival? Haitians without status in the Bahamas

Recent scholarship contends that collective action emerges when human rights are violated. This article investigates why Haitians without status in the Bahamas have yet to mobilize collectively for basic rights and protections, despite discrimination and exploitation. The article examines two analogies to explain their immobilization. The analogy of dry land drowning utilizes Goffman's Stigma (1963) framework to describe how social prejudice hinders the ability of Haitians without status to act, while the analogy of rip current survival explains how institutional drawbacks pull Haitians without status away from movement activity through a political process analysis. The article contends that both interpretations are inadequate when taken alone and provides suggestions for future research into Bahamian-Haitian relations.     

DNase I and Proteinase K eliminate DNA from injured or dead bacteria but not from living bacteria in microbial reference systems and natural drinking water biofilms for subsequent molecular biology analyses

Molecular techniques, such as polymerase chain reaction (PCR) and quantitative PCR (qPCR), are very sensitive, but may detect total DNA present in a sample, including extracellular DNA (eDNA) and DNA coming from live and dead cells. DNase I is an endonuclease that non-specifically cleaves single- and double-stranded DNA. This enzyme was tested in this study to analyze its capacity of digesting DNA coming from dead cells with damaged cell membranes, leaving DNA from living cells with intact cell membranes available for DNA-based methods. For this purpose, an optimized DNase I/Proteinase K (DNase/PK) protocol was developed. Intact Staphylococcus aureus cells, heat-killed Pseudomonas aeruginosa cells, free genomic DNA of Salmonella enterica, and a mixture of these targets were treated according to the developed DNase/PK protocol. In parallel, these samples were treated with propidium monoazide (PMA) as an already described assay for live-dead discrimination. Quantitative PCR and PCR-DGGE of the eubacterial 16S rDNA fragment were used to test the ability of the DNase/PK and PMA treatments to distinguish DNA coming from cells with intact cell membranes in the presence of DNA from dead cells and free genomic DNA. The methods were applied to three months old autochthonous drinking water biofilms from a pilot facility built at a German waterworks. Shifts in the DNA patterns observed after DGGE analysis demonstrated the applicability of DNase/PK as well as of the PMA treatment for natural biofilm investigation. However, the DNase/PK treatment demonstrated some practical advantages in comparison with the PMA treatment for live/dead discrimination of bacterial targets in drinking water systems.     

The ‘other side’ of embedded ness: A case‐study of the interplay of economy and ethnicity

As interest in ethnics and their entrepreneurial activities has grown in recent years, sociologists have come to emphasize the importance of ethnic social structures as the source of actions propelling business growth. In a sign of convergence with the ‘new economic sociology’, recent literature suggests that embeddedness in ethnic networks and communities leads to cooperative, if not conformist, behaviour among ethnic economic actors. This article looks at the ‘other side’ of embeddedness, through a case‐study of African‐American, Caribbean, Korean and white construction contractors in New York City. I argue that, in construction, the embeddedness of economic behaviour in ongoing social relations among a myriad of social actors impedes access to outsiders. Embeddedness contributes to the liabilities of newness that all neophytes encounter, breeding a preference for established players with track records. However, the convergence of economic and ethnic ties has a further baneful effect, since outsiders also fall outside those networks that define the industrial community. While African‐American, Caribbean and Korean outsiders all experience these barriers in similar ways, they differ in the adaptive strategies that they have pursued. African Americans appear to be most disadvantaged, in part because they have been the most exposed to the social closure that results from the mobilization of white ethnics’ social capital. By contrast, Caribbeans and Koreans entered the labour market in societies where racial domination played little or no role in labour market outcomes ‐ a considerable asset since construction skills are transferable from one society to another. The Koreans appear to be the most embedded in ethnic networks, through which they secure jobs and skilled labour, though class factors play a role here as well and even the Koreans must reach out beyond the ethnic community for a clientele. By contrast, ethnic solidarity operates less powerfully among the black contractors, who are tied to a community where intra‐ethnic diversity and internal competition have grown as a result of immigration. In the absence of an ethnic market, black'entrepreneurs turn to the state, whose requirements and dependence on union labour expose black builders to risks from which their Korean counterparts are sheltered.     

Age differences in tactile pattern recognition at the fingertip

Young (21–26 years, n?=?20) and old (55–86 years, n?=?25) participants were tested for their ability to recognize raised letters (6-mm high, 1-mm relief) by touch. Spatial resolution thresholds were also measured with grating domes to derive an index of the degree of afferent innervation at the fingertip. Letter recognition in the young group was very consistent and highly accurate (mean, 86% correct), contrasting with the performance of the old group, which was more variable and comparatively low in accuracy (mean, 53% correct). In both groups, spatial resolution thresholds accounted for a substantial portion of the variance in the performance, suggesting a strong link between age-dependent variations in tactile innervation and recognition accuracy. The patterns of errors in the old group showed that an inability to encode internal elements specific to certain letters was at the source of most confusion among letters. Whether this inability reflected only deficient peripheral encoding mechanisms or some other alterations at the central level is discussed.     

Roma women in Athenian firms: do they face wage bias?

In the current study, we analyse the effect of having a Roma background on women's wages. By utilizing data from sixteen multiethnic municipalities in which Roma live, we estimate that 66.2 per cent of the wage differential between Roma and non-Roma female workers cannot be explained by differences in observed characteristics. Prejudices against Roma women are discussed and appear to explain the wage gap found here. The occupational segregation of the Roma in low-paid jobs and employers' statistical motivations are also found to influence wages earned by Roma. This study concludes that there is a need for better implementation of existing laws, rules and regulations, which would counter the discrimination against minority women in the labour market. In addition, a better means of assessing workers' skills might contribute to the reduction of wage discrimination, and greater educational achievement would significantly boost the economic status of Roma women.     

Exclusive recognition: against reductionism and distortion

This article analyses two dominant discourses of racial politics in Hawai'i and the work they do naturalizing haole (white people or whiteness in Hawai'i) in the islands. The first is the well-worn discourse of racial harmony representing Hawai'i as an idyllic racial paradise with no conflict or inequality. Frequently contrasting the islands with the ‘racist mainland’, this discourse circulates among many communities and is widely referenced. There is also a competing discourse of discrimination against non-locals which contends that haoles and non-local people of colour are disrespected and treated unfairly in Hawai'i. As negative referents for each other, these discourses work to reinforce one another and are historically linked. I suggest that the question of racial politics be reframed towards consideration of the processes of racialization themselves – towards a new way of thinking about racial politics in Hawai'i that breaks free of the not racist/racist dyad.     

Chiral discrimination and interaction mechanism between enantiomers and serum albumins

The chiral discrimination studies of biological system are theoretically and practically significant for the development of chiral drugs and life science. Our work has embarked upon the interaction between serum albumin (SA) (including human SA and bovine SA), R,S‐1‐(4‐methoxyphenyl)ethylamine, and R,S‐1‐(3‐methoxyphenyl)ethylamine. The formation of intermediate transition state, binding sites, and chiral discrimination ability can be investigated by ultraviolet‐visible spectra and fluorescence spectra. Moreover, both the changes of hydrophobic microenvironment and energy transfer can be detected by synchronous fluorescence spectra and fluorescence lifetime. Copyright © 2013 John Wiley & Sons, Ltd.
