The social adjustment of Filipino nonmigrants,emigrants, and immigrants to Hawaii     

Jonathan Y Okamura  Richard Coller 《Int J Intercult Relat》1978,2(3):295-308

This study compared the social adjustment of a group of Filipinos who had initiated definite arrangements to emigrate to Hawaii (emigrants) with another group of Filipinos from the same communities as the emigrants who expressed no intention to emigrate (nonmigrants). These two samples were then compared with a group of recent Filipino immigrants to Hawaii. Social adjustment was measured by the Katz Adjustment Scales, relative's rating form, in terms of clusters of symptomatic and social behavior. The results showed that the immigrants in their social adjustment were less emotionally expressive than the emigrants, who were in turn, less expressive than the nonmigrants. However, significant cluster score differences obtained primarily between the Philippine samples and the immigrants, while there was a general lack of significance between the nonmigrants and the emigrants. The overall decline in the level of emotional expression of the immigrants was attributed to their adherence to the paramount Philippine value of social acceptance as their modal means of adjustment to the immigration experience. Thus, the direction and nature of changes in the emotional expression of Filipino immigrants follow from their culture and its integral norms and values rather than being derivative of processes of acculturation.  相似文献   

Surface modification on polydimethylsiloxane-based microchannels with fragmented poly(l-lactic acid) nanosheets     

Lu Yang  Yosuke Okamura  Hiroshi Kimura 《Biomicrofluidics》2015,9(6)

Surface modification is a critical issue in various applications of polydimethylsiloxane (PDMS)-based microfluidic devices. Here, we describe a novel method through which PDMS-based microchannels were successfully modified with fragmented poly(l-lactic acid) (PLLA) nanosheets through a simple patchwork technique that exploited the high level of adhesiveness of PLLA nanosheets. Compared with other surface modification methods, our method required neither complicated chemical modifications nor the use of organic solvents that tend to cause PDMS swelling. The experimental results indicated that the modified PDMS exhibited excellent capacity for preventing the adhesion and activation of platelets. This simple yet efficient method can be used to fabricate the special PDMS microfluidic devices for biological, medical, and even hematological purposes.  相似文献   

Intercultural Encounters as Religious Education: Japanese Students at a Christian University and their Religious Transformation     

Naoki Okamura 《Religious education (Chicago, Ill.)》2013,108(3):289-302

It is commonly acknowledged by many that Japanese teenagers in general hold very negative views of organized religions. However the researcher, as an educator at a Christian University in California, observed every year a great number of Japanese international students becoming persons who paint positive pictures of religion. A study done on those students, utilizing the method of grounded theory, uncovered the following. One, their cross-cultural experiences created crisis situations, which became a catalyst to question their uncritical beliefs about religion. Two, their positive personal encounters with religious people in the United Sates caused them to experience transformation.  相似文献
