This paper examines the various ways in which the concept of “diaspora” has important implications for rethinking traditional notions of acculturation in Psychology. In this paper, we argue that the idea of a fixed, invariant, and apolitical notion of acculturation dominates much of Psychology, and as such it needs to be revised and reexamined in light of transnational migration and global movements. Drawing on our previous and current scholarship on acculturation and identity [Bhatia, S., & Ram, A. (2001). Rethinking “acculturation” in relation to diasporic cultures and postcolonial identities. Human Development, 44, 1–17; Bhatia, S., & Ram, A. (2004). Culture, hybridity and the dialogical self: Cases from the South-Asian diaspora. Mind, Culture, and Activity, 11(3), 224–241; Bhatia, S. (2007a). American Karma: Race, culture, and identity and the Indian diaspora. New York, NY: New York University Press; Bhatia, S. (2008). Rethinking culture and identity in psychology: Towards a transnational cultural psychology. Journal of Theoretical and Philosophical Psychology, 28, 301–322], we provide a counterargument to models of acculturation that claim that all immigrants undergo a universal psychological process of acculturation and adaptation. More specifically, we show how members from the Indian diaspora reexamined their acculturation status after the events of 9/11. We use interdisciplinary research to critically examine the role of race in the acculturation process. In addition, we provide a new analytical framework to understand the larger structural forces that shape the acculturation and assimilation process of transnational and diasporic migrants. 相似文献

In previous studies, we have reported first in vivo evidence of copper deposition in the choroid plexus, cognitive impairments, astrocytes swelling (Alzheimer type II cells) and astrogliosis (increase in number of astrocytes), and degenerated neurons coupled with significant increase in the hippocampus copper and zinc content in copper-intoxicated Wistar rats. Nonetheless, hippocampus iron levels were not affected by chronic copper-intoxication. Notwithstanding information on distribution of copper, zinc and iron status in different regions of brain due to chronic copper exposure remains fragmentary. In continuation with our previous study, the aim of this study was to investigate the effects of intraperitoneally injected copper lactate (0.15 mg Cu/100 g body weight) daily for 90 days on copper, zinc and iron levels in different regions of the brain using atomic absorption spectrophotometry. Copper-intoxicated group showed significantly increased cortex, cerebellum and striatum copper content (76, 46.8 and 80.7 % increase, respectively) compared to control group. However, non-significant changes were observed for the zinc and iron content in cortex, cerebellum and striatum due to chronic copper exposure. In conclusion, the current study demonstrates that chronic copper toxicity causes differential copper buildup in cortex, cerebellum and striatum region of central nervous system of male Wistar rats; signifying the critical requirement to discretely evaluate the effect of copper neurotoxicity in different brain regions, and ensuing neuropathological and cognitive dysfunctions. 相似文献

This paper examines perceptions of professional and organizational identity of teacher educators in a ‘new’ University of Technology in South Africa, resulting from several recent mergers of colleges of education and colleges of technology mainly serving formerly disadvantaged students and schools. The findings show that most staff consider teaching and research as dichotomous. Research activities are seen to satisfy the institutional requirements for securing research funding and producing publications. Professional identities could be strengthened by a faculty-wide debate on the specific profile of teacher education in a University of Technology, resulting also in an agreed research ethos. Peer support in collaborative research groups with a focus on own practice is seen as an opportunity to strengthen research expertise. 相似文献

The civic potential of Bollywood based dance flash mobs: on youth participation and digital networks
Kiran Bhatia 《亚洲交流杂志》2013,23(6):483-499
In this paper I argue that artists/activists in India use Bollywood dance and songs to choreograph flash mob performances with the aim of addressing issues of public importance because Bollywood is a common performative site that can be used to mobilize people. In order to understand how Bollywood based dance flash mobs have civic potential for activists-cum-performers, I conducted in-depth interviews with 20 flash mob choreographers in four cities of India. Based on my findings, I suggest that Bollywood based dance flash mobs are identified by the urban youth as inherently political and democratic in nature. These performances are often accompanied with the organizer-generated subgenre of flash mob videos recorded for the online audience. In archiving these performances, organizers also enable a virtual network of connections where individuals who share the same civic aspirations can come together and build solidarity around the cause. 相似文献

Montgomery multiplication over rings 总被引：1，自引：0，他引：1
Montgomery multiplication of two elements a and b of a finite field Fq is defined as abr-1 where r is a fixed field element in . In this paper we define Montgomery multiplication of elements a(x) and b(x) in a polynomial ring modulo the ideal generated by a reducible polynomial f(x). We then show that Montgomery multiplication over a field represented by a polynomial ring modulo an irreducible pentanomial can be performed more efficiently in terms of time delay by embedding the field in a quotient of a polynomial ring modulo a reducible trinomial. The trinomial has a degree that is slightly higher than that of the pentanomial, thereby increasing the number of gates in the multiplier by a small amount. 相似文献

Psoriasis is a common and an inflammatory skin disease. Trace elements play an important role in the skin metabolism such as keratinisation and melanin formation as well as immunological and inflammatory reactions. Henceforth, the present study was aimed to evaluate the essential metals with special reference to Cu and Zn. In this study, 72 psoriatic patients and 50 controls were enrolled. On the basis of PASI score psoriatic group comprising of 48 mild and 24 severe psoriatic patients were grouped. The serum trace elements analysis in the subjects revealed that serum Cu levels and Cu/Zn ratio was significantly higher in the psoriatic patients as compared to controls. Interestingly, severity of the psoriasis was well correlated with the serum Cu levels. Taking together, all these findings suggest that Cu may be a major culprit in the pathogenesis as well as in the severity of the disease. 相似文献

Evidence of the value of constructivist theory in the classroom is especially important for educational practice in areas of poverty and social challenge. Research was undertaken in 2010 into the application of constructivist theory on instructional design. The findings of this research are particularly relevant to the current curricular crisis in South Africa which threatens to side-line constructivist priorities and return learners to rote learning from textbooks. The findings are situated here within the national debate over curricular design and instructional models. Placing instructional design within the larger context of national pedagogical contestation provides important evidence of the central role of Freirean imperatives for South Africa’s educational future. This article indicates that a constructivist framework, when pertinently arranged, provides holistic and sustainable procedures for knowledge creation. The findings from the research project showed that, in an environment conducive to learning, learners become self-motivated and better able to master the next phase of the curriculum. As a result of the constructivist framing, participants grew into strategic and effective learners who took responsibility for their own learning. These findings add weight to the call for reconsideration of constructivist foundations in national curriculum design. 相似文献

The circadian periodicity of plasma lipid peroxide levels and activities of superoxide dismutase (SOD), catalase (CAT) and
glutathione peroxidase (GPx) were studied in 50 clinically, bacteriologically and radiologically proven fresh cases of pulmonary
tuberculosis (age: 21–45 years) and 60 age-matched healthy volunteers with diurnal activity from 06∶00 to about 22∶00 and
nocturnal rest. A marked circadian variation in plasma lipid peroxide level was recorded in healthy subjects and pulmonary
tuberculosis patients with significant amplitude and acrophase around 16∶21 and 17∶12 respectively. The acrophase tended to
be delayed in tuberculosis patients. Furthermore, a statistically significant circadian rhythm was found in SOD, CAT and GPx
activities in normal volunteers and pulmonary tuberculopsis patients. SOD and CAT enzyme activity was noted to be maximum
at 06∶00 and minimum at 00∶00 in tuberculosis patients. The circadian acrophase for GPx activity was recorded at 16∶15 in
normals and around 22∶45 in patients. Moreover, the activity was found to be decreased at all sampling hours during 24-hours
sleep-awake period in patients in comparison to healthy counterparts. The MESOR and circadian amplitude also decreased markedly.
The decreased activity of measured antioxidant enzymes in pulmonary tuberculosis patients could probably be associated with
oxidative stress and/or decreased anti-oxidant defensive mechanism in such patients. 相似文献
