日本的中苏大论战研究综述

中苏大论战是国际共产主义运动史上的一个重大事件,这场论战给国际共产主义运动乃至于世界政治格局都带来了深刻影响.与其他各国学者一样,日本学者也对这一历史事件进行了深入的研究.对日本学术界有关中苏论战爆发的原因、论战涉及的理论问题以及论战所带来的历史教训等研究成果进行了梳理和分析,对深化中苏论战的认识有深远的意义.     

Legacy and legitimacy: historical ethnography of a judo dojo in Montréal,Canada

Through fieldwork in a judo dojo (gym) in Montréal, Canada, the author found that assuming the members’ practice as embodiment of identity does not resonate with the actual practice they are producing. Instead of framing the practice as identity politics, this study focuses on the practice itself to highlight agency and practice within the social conditions in transformation. By adapting a historical ethnographic approach, this paper describes how the past is connected to the present as ‘actant’ to produce present practice. The paper discusses that there is little momentum of the people pursuing ‘distinction’, and their emphasis is on the continuity of their practice. Drawing on the pragmatic sociological approach, this study further discusses how legacy and legitimacy are constructed to produce their practice.     

Bile canaliculi formation by aligning rat primary hepatocytes in a microfluidic device

In this study, we propose a microfluidic cell culture device mimicking the microscopic structure in liver tissue called hepatic cords. The cell culture area of the device was designed to align hepatocytes in two lines in a similar way to hepatic cords. Thanks to the structural design together with a cell seeding procedure, rat primary hepatocytes were successfully aligned in two lines and cultured under perfusion condition. It is shown that aligned hepatocytes gradually self-organize and form bile canaliculi along the hepatic cord-like structure. The present technique to culture hepatocytes with functional bile canaliculi could be used as an alternative to animal testing in the field of drug discovery and toxicological studies, and also be beneficial to tissue engineering applications.

Job search motivation of part-time or unemployed Japanese college graduates

We clarify how individuals actively interact with socio-cultural contexts to attain regular employment in Japan. Based on a large sample (N = 3,512) of part-time employed and unemployed college graduates (23–39 years old), we found that: Career decision making self-efficacy predicted job search; a lack of both hope and fulfillment motivated job search, while having hope promoted it; wishing for perfect vocation and being free from both inclination towards personal interests and passivity motivated job search. Clients’ desire for “a perfect vocation,” should not necessarily be considered as a career barrier but, perhaps, rather as an asset for motivating job search. Counselors should seek to better understand the influence of clients’ socio-cultural contexts on their career attitudes.     

R&D portfolios and pharmaceutical licensing

We examine how R&D portfolios of drug pipelines affect pharmaceutical licensing, controlling firm size, diversity, and competition. The data collected comprises 434 license-ins and 329 license-outs closed by 54 Japanese pharmaceutical companies between 1997 and 2007. We pay special attention to stage-specific licensing by dividing the innovation process into early and late stages. Joint estimates of license-in and license-out using seemingly unrelated regressions (SUR) reveal that drug pipelines significantly affect stage-specific licensing, inducing portfolio effect that lead to smoothing drug pipelines across early and late stages.     

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

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.     

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

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.
