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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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

AbstractThe purpose of this study was to examine the changes in the metabolic state of quadriceps femoris muscles using transverse relaxation time (T2), measured by muscle functional magnetic resonance (MR) imaging, after inactive or active recovery exercises with different intensities following high-intensity knee-extension exercise. Eight healthy men performed recovery sessions with four different conditions for 20 min after high-intensity knee-extension exercise on separate days. During the recovery session, the participants conducted a light cycle exercise for 20 min using a cycle (50%, 70% and 100% of the lactate threshold (LT), respectively: active recovery), and inactive recovery. The MR images of quadriceps femoris muscles were taken before the trial and after the recovery session every 30 min for 120 min. The percentage changes in T2 for the rectus femoris and vastus medialis muscles after the recovery session in 50%LT and 70%LT were significantly lower than those in either inactive recovery or 100%LT. There were no significant differences in those for vastus lateralis and vastus intermedius muscles among the four trials. The percentage changes in T2 of rectus femoris and vastus medialis muscles after the recovery session in 50%LT and 70%LT decreased to the values before the trial faster than those in either inactive recovery or 100%LT. Those of vastus lateralis and vastus intermedius muscles after the recovery session in 50%LT and 70%LT decreased to the values before the trial faster than those in 100%LT. Although the changes in T2 after active recovery exercises were not uniform in exercised muscles, the results of this study suggest that active recovery exercise with the intensities below LT are more effective to recover the metabolic state of quadriceps femoris muscles after intense exercise than with either intensity at LT or inactive recovery. 相似文献
