哈萨克语中汉语借词的层级分析

根据表现形式、借用方法、渗透程度,可以将哈萨克语中的汉语借词由低到高分为四层：低层、半低层、中间层、半高层,不同层级汉语借词之间的联系体现为：上层汉语借词是下层汉语借词的深化。不同层级汉语借词的进入过程反映出汉语、哈萨克语在接触中显性——隐性——异质的跨界,亦即语音——词汇——语法的渗入,汉语对哈萨克语的影响过程为吸收——改造——趋同。     

Investigating direct and indirect globalization-based acculturation

Cultural globalization affects most people around the world in contemporary, modern societies. The resulting intercultural contact have been examined using the theory of globalization-based acculturation. However, little is known about possible differences and similarities in processes underlying the effects of direct (e.g., through contact with immigrants) and indirect (e.g., engagement with cultural elements through media) forms of new cultural exposure. Drawing on the contact hypothesis, social identity theory, and symbolic threat theory, we examined whether perceived intercultural threat and local and global identities would explain whether both forms of contact result in multicultural acquisition or in ethnic protection. In Study 1 (N = 402), indirect, but not direct, intercultural contact was positively associated with multicultural acquisition; and both types of intercultural contact were negatively linked with ethnic protection. Global identity significantly mediated the association of both direct and indirect intercultural contact with both multicultural acquisition and ethnic protection, whereas perceived cultural threat only significantly mediated the associations of direct intercultural contact with multicultural acquisition and ethnic protection. In Study 2 (N = 424), higher levels of ethnic protection, and lower levels of multicultural acquisition, emerged in the experimental group primed with indirect, versus direct, intercultural contact. Furthermore, intercultural threat was negatively, and global identity positively, associated with multicultural acquisition, while intercultural threat was positively, and global identity negatively, associated with ethnic protection. Results are discussed in relation to similarities and differences across direct and indirect intercultural contact, providing a nuanced understanding of contemporary intercultural contact and globalization-based acculturation among majority populations.     

Theaters of war: Tracing the strange careers of Shina No Yoru in the military contact zones of the Pacific, 1937–1954

This article examines the ways in which multiple traditions of camp shows and the overlapping and relational layers of Imperial Japan and U.S. presence in Korea shaped Korean entertainers’ lives after 1945, producing their idiosyncratic performances in response to rapid shifts in Korea’s relations with Japan and the United States in the 1940s–1950s. When the United States sought to reposition Japan at the top of the newly emerging American hegemonic order of Asian countries, Korean entertainers who served the Imperial Japanese Army a few months earlier found themselves performing for American soldiers. The stage of the Korean native camp shows became a “strange and exotic” yet “familiar and even comforting” place where inconsistent logics, such as Imperial Japan’s pan-Asian ideology and American Orientalist fantasy, mingled. Under the complicated legacies of overlapping militarization and colonization in Korea, militarization has constituted a structuring force that enabled Korean women camp show entertainers generating their hybrid performance styles in ironies, contradictions, and complexities. Building on postcolonial theorists’ notion of hybridity, I argue that Korean entertainers’ performances were being shaped or negotiated in contact with different audiences and expectations as well as Korean entertainers attempted to navigate the acceptable ground of performances and womanhood in the constantly changing political and ideological environment.     

Choose your (international) contacts wisely: A multilevel analysis on the impact of intergroup contact while living abroad

A two year longitudinal study examined the influence of social contact abroad on student sojourners’ cultural adjustment and intergroup affect. Social contact was measured with regard to the three people that sojourners (exchange students) spent most time with. Both the quality of the relationship with each contact and the cultural background (host national, co-national) of each contact were measured, that is contact quality and contact source, respectively. The data were analysed through repeated measures multilevel modelling. Results indicate that good quality contact (independent of source) is associated with higher cultural adjustment in sojourners and lower levels of stress. Contact quality however, was not associated with intergroup affect. Source of contact was found to matter, especially over time. Specifically, in the later stages of the sojourn, having more co-national contacts among ones three most frequent contacts, was associated with higher levels of stress, reduced cultural adjustment and higher secondary outgroup derogation. These findings suggest that who sojourners have contact with, matters for both cultural adjustment and intergroup affect.     

Narrations on intercultural experiences in South African contact zones

The study is anchored in Pratt’s theory on ‘contact zones’ (CZ) and explores CZs in Gauteng-Province in Post-Apartheid South Africa, where experiences are influenced by highly diverse and hybrid cultural and language backgrounds. This article presents autoethnographic narrations of experiences of South Africans, addressing the void of emic perspectives in CZs in South Africa.Methodologically, the study follows a qualitative research design and is anchored in the social constructivist research paradigm, using 19 narrations of individuals. Four narrations, which mirror the experience of individuals from South African minority groups (Coloured and Indian) are presented in more depth in this article. Findings are analysed through content analysis. Limitations and ethical considerations are highlighted.Findings show the described experiences in CZs with regard to four categories: intercultural conflict, intercultural identity development, intercultural communication and its barriers, and intercultural non-verbal communication. They mirror predominant themes in South African contemporary society with specific focus on CZ experiences of minority group members, present boundaries created through the experience and narration of difference and possible ways to deal constructively with diversity within selected CZs. Conclusions are drawn and recommendations for future theory and practice are given, not only for the South African context, but also for constructive intercultural relations elsewhere.     

Positive and negative intergroup contact and willingness to engage in intergroup interactions among majority (Han) and minority (Uyghur) group members in China: The moderating role of social dominance orientation

The present study investigated whether the associations of positive and negative intergroup contact with behavioral intentions (intentions to have contact with the outgroup in the future) are moderated by social dominance orientation (SDO), by considering the perspective of both majority and minority group members in China. Participants were 325 Han (majority) and 373 Uyghur (minority) members, who completed a self-report questionnaire. Results indicated that positive contact was associated with more positive behavioral intentions among high-SDO majority group members, whereas SDO did not moderate the association between positive contact and behavioral intentions among minority group members. In addition, negative contact was associated with lower behavioral intentions among high-SDO majority group members, and among low-SDO minority group members. This study suggests that attention should be placed simultaneously on positive and negative contact and on individual difference variables relevant to social ideologies, such as SDO.     

Intercultural Interaction at a Multicultural University: Students' Definitions and Sensemakings of Intercultural Interaction

Abstract

This essay examines how racially or ethnically different students define, make sense of, and evaluate intercultural interaction at the multicultural university. Eighty qualitative in-depth interviews were conducted with university students of varied backgrounds. These interview sessions access students' definitions, sensemakings, and experiences of on-campus intercultural interaction as it has played out in their lives. The findings demonstrate that interviewees equate intercultural interaction with being present in demographically diverse settings. Moreover, this study reveals that definitions and sensemakings of intercultural interaction vary among interviewees primarily based on their racial or ethnic background. Latino/a, Black/African American, White/European American, and Asian American interviewees define and make sense of intercultural interactions in culturally specific ways and in relation to their historical experiences.     

Direct and Mediated Intercultural Contact: Koreans' Attitudes toward U.S. Americans

Abstract

Guided by the intergroup contact hypothesis, this study tested two models examining the associations among Korean young adults' consumption of U.S. dramas, direct contact with a U.S. American person, and their attitudes toward U.S. Americans in general. Results demonstrated that personal contact and mediated contact had a positive effect on intergroup attitudes, but that frequency of personal contact was a negative contributor. Mediated contact had different and stronger influences on participants' intergroup attitudes when they did not have personal contact with U.S. Americans. In addition, intergroup anxiety played a significant role in the contact modes and attitudes links.     

Ingroup norms, intergroup contact and intergroup anxiety as predictors of the outgroup attitudes of majority and minority youth

This study focused on the interplay of perceived parental and peer norms and the quality of intergroup contact in predicting outgroup attitudes among majority and minority youth. In addition, the role of intergroup anxiety on the contact-attitude association was studied simultaneously with the effects of social norms. 225 adolescents (93 Finnish majority and 132 Russian-speaking minority youth) were surveyed. As was hypothesized, the effects of intergroup contact and social norms on the outgroup attitudes were different depending on the group status: perceived norms and the quality of intergroup contact had a joint effect on outgroup attitudes only among minority youth. While perceived norms and contact experiences affected the outgroup attitudes of majority group members independently of each other, minority group members’ negative contact experiences were associated with negative attitudes towards the majority only when the perceived ingroup norms supported the expression of negative attitudes. Surprisingly, intergroup anxiety mediated the contact-attitude association only in minority youth, and the effect of contact quality on outgroup attitudes was stronger among the minority than among the majority. The results are discussed in relation to the specific intergroup context in question. It is suggested that both positive ingroup norms and pleasant personal contact experiences play a crucial role in the formation of positive attitudes among minority as well as majority youth, and in some contexts positive norms may be even more important than positive intergroup contact.
