Globalisation and increased patterns of immigration have turned workplace interactions to arenas for intercultural communication entailing negotiation of identity, membership and ‘social capital’. For many newcomer immigrants, this happens in an additional language and culture – English. This paper presents interaction experiences of four non-native English language teachers with other institutional members. It uses a sociocultural perspective of second language to map their approaches to negotiations of professional and institutional identities in and through these interactions. Their discussions highlight the role of language, cultural practices and the emic socio-political factors embedded within institutional interactions in individuals' identity negotiation and integration. 相似文献

Postmodern institutional interactions in Australian universities, among students and staff, entail negotiation of identity, legitimacy, and ‘social capital’. For many international students, this happens in an additional language and culture, in English. The case study presented here profiles four international non-English speaking background Ph.D. students in an Australian university, observes their out-of classroom departmental interactions, and uses a sociocultural perspective of second language in use to map their approaches to the negotiation of institutional identity. Two focus group interviews with the participants illustrated how, despite similarities among the participants in the beginning as newcomers to a Western university, students chose different pathways for integration, engagement in institutional interactions, and identity construction. The discussions highlight the role of agency and intentionality in participation and learning through interaction which leads to a critique of the ‘international student' as a label that underplays student agency. 相似文献

Elevated Apolipoprotein B Apolipoprotein A-I ratio is a risk factor for predicting coronary artery disease (CAD). Paraoxonase
1 (PON1) is a high density lipoprotein (HDL) associated serum enzyme. PON1 protects lowdensity lipoproteins (LDLs) from oxidative
modifications and thus has a protective effect against CAD progression. There are two common polymorphisms, Q192R and L55M,
in PON1 gene. There may be a relationship between these polymorphisms and elevated ApoB/ApoA-I ratios. Therefore, we decided
to evaluate effect of these polymorphisms on individuals with high and normal ApoB/ApoA-I ratios. To evaluate Q192R and L55M
polymorphisms in Iranian case group (n=75) with high ApoB/ApoA-I ratio, and control group (n=75) with normal ApoB/ApoA-I ratio,
we carried out PCR using specific primers. Then, we digested PCR products by RFLP. ApoB and ApoA-I levels were determined
by immunoturbidimetry method. Genotype frequencies for Q192R were determined: 49.3%QQ, 44%QR, 6.7%RR in case group, and 53.3%QQ,
33.3%QR, 13.4%RR in controls (P= 0.236). Genotype frequencies for L55M were determined: 21.3%LL, 68%LM, 10.7%MM in case group
and 42.7%LL, 52%LM, 5.3%MM in controls (P= 0.016). A significant relationship between L55M polymorphism and familial history
of cardiovascular disease was found (P= 0.011). In our study PON1L55M polymorphism was associated with high ApoB/ApoA-I ratios
in case group. Thus, L55M polymorphism may be an independent risk factor for cardiovascular disease. Since L55M polymorphism
was associated with familial history of cardiovascular disease, it is better to evaluate L55M polymorphism in younger ages
even in the absence of high ApoB/ApoA-I ratios. 相似文献

This study is aimed to investigate the nanoliposomal artemisinin preparation, and its implementation on breast cancer cells. Side effects have been one of the common challenges of drug usage, as well as cancer treatment. In order to reduce such effects, nanotechnology has been a great help. Nanoliposomes are provided through reverse phase evaporation. In this method, certain proportions of phosphatidylcholine, cholesterol and artemisinin were mixed together. Besides, the obtained formulation was pegylated by using polyethylene glycol 2000 in order to increase its stability and solubility. The mean diameter of non-pegylated and pegylated liposomal artemisinin was determined by Zeta sizer system. The percent of drug released from liposome was performed by dialysis. The encapsulation efficiency of both formulations was estimated by spectrophotometry method. As a result, encapsulation and drug release of nanoliposomal formulation were more than the pegylation of the same formulation. In addition, this study indicated that cytotoxicity effect of pegylated nanoliposomal artemisinin was more, in comparison with nanoliposomal artemisinin. 相似文献

This case study profiles eight international PhD students and describes the process of the construction and negotiation of their social and institutional identities in an Australian university. Audio-recorded informal conversations of the students highlight the role of social membership, staffroom interactions and language in the construction of institutional identities. The impact of multiple identity transitions experienced by new international students is described. The data analysis uses a sociocultural perspective of second language in use, which reflects the negotiation of power, space and identity in informal multicultural institutional encounters. The article provides insight into the ways transitions are experienced by international postgraduate students. Findings also include a critique of the negatively loaded stereotype of the ‘international student’ in Australian universities and the way it underplays the heterogeneity of student experience. 相似文献
